Definitions
- the present application relates to a method and apparatus for the opening and filling of flexibly sided containers such as bags having at least one opening therein.
- the present application relates to a device for the treatment of flexible, tubular structures, for example bags, with at least one gripper pair holding the structure and having at least one leading gripper and one trailing gripper, whereby the leading gripper and the trailing gripper are mounted on separate guide trains that can be moved relative to one another, and further whereby the two guide trains are each motor driven independently of one another, and whereby the guide trains are configured so as to be motor-displaceable relative to one another so as to vary a distance between the grippers and/or a distance between the gripper pairs.
- the separate guide trains may be independently moved with one or at least one motor arrangement.
- a motor arrangement may comprise a motor and one or more clutch arrangements, rods, cams, or other devices to effectuate independent movement of the separate guide trains and be within the scope of the present application.
- Some devices to accept different bags of varying bag widths, the distance between the leading gripper and the trailing gripper is modified. This is done by means of a phase adjustment of the associated motors.
- the bags can be produced from flat sheets of wrapping material that is pulled off the roll and cut to form the individual bags.
- the individual bags are sealed at the end opposite the opening by e.g. thermal sealing, ultrasound or bonding or similar processes.
- the device in question can, of course, also be used for the treatment of premade bags or similar flexible, tubular structures.
- the key point is that the structures or bags are forwarded for subsequent processing. This not only includes filling as described above, but also such things as the attachment of spouts, adapters and valves.
- the bags can also be contoured or labels, tags, tabs, etc., can be applied to the bags.
- subsequent processing steps or treatment of the bags can include processes such as flushing with inert gas, sterilization or dust extraction.
- Some horizontal, flat bag machines or bag sealing machines work with an internal double-rod gripper system, which holds the bag in position for processing while itself remaining stationary.
- an external double-rod gripper system which is powered and moves forward and back to grasp the respective bag. The bag is then transported and released, whereby the interaction between the two double-rod gripper systems moves the respective bag forward.
- Some devices therefore turn to a complex solution that requires or desires a plurality of components. Furthermore, replacement of the grippers to retool the device for bags with a different exterior contour and/or different exterior dimensions is difficult and requires or desires time-consuming installation.
- Some devices for the treatment of flexible, tubular structures with at least one opening use a carousel equipped with grippers.
- a plurality of gripper pairs are provided over a relatively small diameter, which grippers hold and handle the bags at the two outer, vertical ends.
- the speed of rotation which results in very high centrifugal forces; these machines are thus limited with respect to transport speed.
- the generally small diameter of each carousel permits metering with at most two different metering devices or filling nozzles.
- An object of the present application is to refine such a device for the treatment of flexible, tubular structures with at least one opening, for example bags, so as to enable simple and fast replacement of the gripper pairs and to provide sufficient space for the attachment of associated metering devices.
- the present application teaches a generic device wherein the leading gripper and the trailing gripper are mounted on separate guide trains that can be moved relative to one another.
- a generic device within the scope of the present application is wherein there is a controller provided that shifts the respective leading gripper by a certain amount in the direction of transport and the respective trailing gripper by the same amount opposite the direction of transport so that the bag middle retains its position even in the event of a bag change.
- the grippers may be moved in relation to one another while both are moving in a direction of transport.
- the leading gripper is that gripper of a gripper pair that leads the gripper pair during the transport of a structure, whereas the trailing gripper follows the leading gripper and thus is the last gripper of the gripper pair relative to the direction of transport or the direction of travel of the grippers.
- the grippers can hold the respective structure or bag in any possible manner; for example, the grippers can be inserted into the opening, spreading the opening per frictional connection until the grippers rest against the walls of the bag.
- the grippers grab the respective bag or structure with clips, by suction, etc., typically with the leading gripper grabbing the front vertical end of the bag relative to the direction of transport or motion and the trailing gripper grabbing the corresponding rear vertical end.
- the two guide trains which are moved relative to one another, are powered by a motor and independently of one another, whereby a separate drive for each guide train is in one possible embodiment to essentially ensure or promote the motion of the guide trains relative to one another described above.
- the two guide trains which are stationary relative to one another, are powered by a motor and independently of one another, whereby a separate drive for each guide train is in one possible embodiment to essentially ensure or promote the motion of the guide trains relative to one another described above.
- the present application essentially ensures or promotes that bags of very different sizes and correspondingly variable openings and/or fill openings and contours can be processed.
- what is required or desired when changing from one type of bag to another is to engage the motors of the guide trains such that the leading gripper and the trailing gripper are moved the same distances, with the leading gripper moving in the direction of transport and the trailing gripper moving opposite the direction of transport.
- both the leading and trailing grippers may be moving in a direction of transport at different speeds and be moved with respect to one another.
- this procedure essentially ensures or promotes that the middle of the bag and thus the plane of symmetry in question remain unchanged during this procedure.
- the present application thus essentially ensures or promotes in this manner that metering devices located relative to the middle of the respective bag continue to meter product into the middle of the bag, including with bags of different dimensions.
- the two guide trains are generally in the form of an endless loop and are also operated as such. Essentially, of course, two independently-driven endless loops are realized, because the two guide trains are laid out separately from one another.
- the guide trains themselves can have one or more conveying devices, such as belts, chains, etc., to which the leading grippers or trailing grippers are mounted separately and independently.
- the leading grippers are mounted on one guide train, the leading gripper train.
- the trailing grippers are likewise mounted on a single guide train, the trailing gripper train.
- both the leading gripper train and the trailing gripper train have their own motor drive and their own conveying devices.
- Both guide trains or gripper trains and their motors are connected to a common controller that is responsible for the motion of the grippers relative to one another.
- a path of motion defined by the two guide trains or gripper trains is linear over at least one segment of defined length. This segment of defined length accounts for the requirements arising from the desire or need to meter different products or components into the structure or the bag.
- the length of the linear segment is defined as a function of the number of metering units, which are generally arranged linearly and in series.
- the path of motion described by the two guide trains or gripper trains is an elongated circle.
- the two grippers are normally on the same side—the processing side—relative to the path of motion described by the guide trains.
- a front and a rear deflector for the grippers or the individual gripper pairs essentially ensure or promote that these continue to circulate around the elongated circular path.
- the distance between the two grippers relative to one another generally corresponds to the width of the bag to be processed or the width of its opening or fill opening.
- the controller also essentially ensures or promotes that the two grippers of each gripper pair are moved apart in a reproducible manner, whereby it is also essentially ensured are promoted that a bag change does not result in a change in the respective bag middles. This essentially ensures or promotes that the bags are reproducibly centered under the corresponding metering unit with the middle of the bag in a fixed position.
- the two guide trains/gripper trains are arranged above one another when viewed from the side. This allows the mounting of the two grippers on mounting plates, from which they extend.
- the mounting plates themselves are mounted on the guide trains or gripper trains arranged one above the other when viewed from the side.
- the guide trains or gripper trains, and with them the leading gripper and the trailing gripper of each gripper pair can be displaced relative to one another, in one possible embodiment by means of a motor, in that the motor of the leading gripper train and that of the trailing gripper train are actuated as specified by the controller for the respective bag.
- a motor in that the motor of the leading gripper train and that of the trailing gripper train are actuated as specified by the controller for the respective bag.
- Both the manual and the motorized displacement of the gripper or guide trains relative to one another does more than make it possible to vary the distance between the grippers.
- the distance between the gripper pairs can also be selectively modified. This distance between the gripper pairs is also called the gripper pair gauge. Motorized and manual displacement can also be combined.
- the present application takes into account requirements saying that a larger bag can and must or should be filled with two instead of four metering devices as was the case previously, for example.
- a larger gripper pair gauge than before is usually used and possibly the speed of the guide trains or gripper trains increased.
- the opposite approach is also plausible.
- the device according to the present application can be easily retooled with other grippers. This further increases the flexibility and enables the device described to be used for almost any application.
- Another option is to divide the leading gripper train, the trailing gripper train or both into segments, which can be assembled into modules. This requires or desires transition stations, e.g., from one leading gripper train to the next leading gripper train, and also synchronization of the motion. That can be accomplished by the common controller.
- inventions or “embodiment of the invention”
- word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”.
- inventions or “embodiment of the invention”
- the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention.
- the Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.

- Processing of the bags 1 means, for example, filling them by means of a metering device 2 .
- this could also mean the application of labels, an overprint, contours, the application or attachment of spouts, adapters, valves, etc.
- the basic configuration of the device comprises at least one gripper pair 3 , 4 , having a leading gripper 3 and a trailing gripper 4 .
- the possible embodiment includes a plurality of leading grippers 3 and trailing grippers 4 .
- Each bag 1 is secured and transported with the help of the associated gripper pair 3 , 4 .
- the gripper pair 3 , 4 holds the bag 1 in question at its opening or fill opening.
- leading gripper or grippers 3 and the trailing gripper or grippers 4 are mounted on different guide trains or gripper trains 5 , 6 , which can be moved relative to one another. In fact, all are most of the leading grippers 3 are mounted on a leading gripper train 5 , whereas, by way of exception, the trailing grippers 4 are mounted on a trailing gripper train 6 for the two guide trains or gripper trains 5 , 6 .
- the leading grippers 3 in the direction of transport or direction of motion R of each gripper pair 3 , 4 assumes a leading position
- the trailing grippers 4 as the name suggests—trail.
- the guide trains 5 , 6 are equipped with separate motorized drives 7 , 8 , which can be impinged independently of one another and are suggested in the figures.
- the motorized drive 7 is a leading gripper train drive 7 , which acts on the leading gripper train 5
- motorized drive 8 is configured as a trailing gripper train drive 8 and impinges the trailing gripper train 6 .
- Both the leading gripper train drive 7 and the trailing gripper train drive 8 are realized in the embodiment as, but are not restricted to, electronic servomotors and are connected to a common controller 9 .
- Both guide trains 5 , 6 are in the form of an endless loop, which in the possible embodiment has the form of an elongated circle.
- the path of motion in direction R defined in this manner by the two guide trains or gripper trains 5 , 6 is linear over at least one segment T of defined length L. Indeed, this segment T of the defined length L allows for the number of metering devices 2 in this example, each of which is arranged in a fixed location.
- the metering devices 2 and the associated processing points can fill the bags 1 without problems, it must or should be essentially ensured or promoted that the middle M of each bag or the center plane of the bag is positioned exactly or virtually exactly or generally below or above the metering devices 2 arranged along the path of motion as the bags circulate.
- the bag 1 in this example can be processed or filled without problems even if bags 1 of different sizes, variable shapes or which otherwise differ from one another are to be treated.
- metering device 2 comprises an upper material holding portion 35 , having a funnel configuration in the embodiment shown, and a lower exiting portion 28 depending downward from material holding portion 35 .
- Bags 1 are disposed with grippers 3 and 4 with the middle M of the opening in bag 1 substantially below exiting portion 28 .
- the materials being metered into bag 1 may flow through exit portion 29 by gravity into middle M of bag 1 as shown by material flow 29 .
- the two guide trains or gripper trains 5 , 6 are arranged or run one above the other when viewed from the side and define the path of motion in question.
- the two guide trains 5 , 6 can include one or more conveying devices such as belts, chains, etc., which are not expressly shown and can also be used in combination.
- the leading grippers 3 and the trailing grippers 4 are mounted separately and independently on the said conveying devices; in one possible embodiment, the leading grippers 3 on the conveying device of the leading gripper train 5 and the trailing grippers 4 on the respective conveying device of the trailing gripper train 6 .
- the distance A between the two grippers 3 , 4 can be varied, e.g. in that the leading gripper train drive 7 impinges the leading gripper train 5 while the trailing gripper train 6 remains stationary. It is also possible to vary a distance B between the gripper pairs 3 , 4 . This distance B between the gripper pairs 3 , 4 is also called the gripper pair gauge.
- the controller can vary both the distance A between the grippers 3 , 4 and the distance B between the gripper pairs 3 , 4 , or the gripper gauge, as a function of the size of the bag 1 to be processed in the example and the number of components desired, and thus the number of metering devices 2 for filling the bag 1 .
- the controller 9 essentially ensures or promotes that the respective leading gripper 3 is shifted by a defined amount C in the direction of transport R, for example, and the corresponding trailing grippers 4 are moved by the same amount C in the direction opposite the direction of transport R.
- the middle M of the bag retains its same position even in the event of a bag change, as is clearly illustrated in FIG. 3 for different bags 1 or for the case of a bag change.
- a bag change is performed more or less at the push of a button, in that the corresponding processing distances A and/or B for the respective bag 1 are queried in the controller and result in a corresponding actuation of the motors or drives 7 , 8 .
- distances A and/or B may be changed with one or at least one motor arrangement.
- a motor arrangement may comprise a motor and one or more clutch arrangements, rods, cams, or other devices to change distances A and/or B.
- the gripper pair gauge can also be modified by the insertion of corresponding spacers. This means that the distances A and/or B can be adjusted both by motor and manually. This accounts for bags 1 of different shapes in the event of a bag change, and also essentially ensures or promotes that the position of the middles M of the bags relative to the guide trains 5 , 6 and thus to the metering devices 2 remains unchanged.
- the grippers 3 , 4 are mounted on mounting plates 11 , 12 , which are best seen in FIG. 1 .

- the inside jaw 102 is fixed to the arm 106 while the outside jaw 104 is movable with respect thereto.
- the outside jaw 104 Upon proper actuation of the first follower 110, the outside jaw 104 is urged away from the inside jaw 102 against the action of the spring clip 108 such that the jaws 102, 104 are opened to a pick position as shown in FIG. 16 to receive an edge of a pouch therein.
- the pick position is utilized at the pick station 34 (FIGS.
- the first follower 110 is released to allow the spring clip 108 to close the jaws 102, 104 and pinch the pouch edge therebetween. At this point the pouch is closed.
- the second follower 112 is actuated against the action of the coil spring 114 which pushes the arm 106 and the pair of jaws 102, 104 forward toward the leading clamp 60 as shown in FIG. 17.

Description
- This application is a Continuation-In-Part application of International Patent Application No. PCT/EP2007/005399, filed on Jun. 20, 2007, which claims priority from Federal Republic of Germany Patent Application No. 10 2006 028 796.7, filed on Jun. 23, 2006. International Patent Application No. PCT/EP2007/005399 was pending as of the filing date of this application. The United States was an elected state in International Patent Application No. PCT/EP2007/005399.
- 1. Technical Field
- The present application relates to a method and apparatus for the opening and filling of flexibly sided containers such as bags having at least one opening therein.
- 2. Background Information
- Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
- The present application relates to a device for the treatment of flexible, tubular structures, for example bags, with at least one gripper pair holding the structure and having at least one leading gripper and one trailing gripper, whereby the leading gripper and the trailing gripper are mounted on separate guide trains that can be moved relative to one another, and further whereby the two guide trains are each motor driven independently of one another, and whereby the guide trains are configured so as to be motor-displaceable relative to one another so as to vary a distance between the grippers and/or a distance between the gripper pairs. It is to be understood that the separate guide trains may be independently moved with one or at least one motor arrangement. A motor arrangement may comprise a motor and one or more clutch arrangements, rods, cams, or other devices to effectuate independent movement of the separate guide trains and be within the scope of the present application.
- Some devices, to accept different bags of varying bag widths, the distance between the leading gripper and the trailing gripper is modified. This is done by means of a phase adjustment of the associated motors.
- Furthermore, some devices for the treatment of flexible, tubular structures take a similar approach. Such machines are used to transfer bags to a processing station, for example, where these bags are filled in most cases with liquid or dry products.
- To this end, the bags can be produced from flat sheets of wrapping material that is pulled off the roll and cut to form the individual bags. The individual bags are sealed at the end opposite the opening by e.g. thermal sealing, ultrasound or bonding or similar processes.
- The device in question can, of course, also be used for the treatment of premade bags or similar flexible, tubular structures. The key point is that the structures or bags are forwarded for subsequent processing. This not only includes filling as described above, but also such things as the attachment of spouts, adapters and valves. The bags can also be contoured or labels, tags, tabs, etc., can be applied to the bags. Finally, subsequent processing steps or treatment of the bags can include processes such as flushing with inert gas, sterilization or dust extraction.
- Some horizontal, flat bag machines or bag sealing machines work with an internal double-rod gripper system, which holds the bag in position for processing while itself remaining stationary. In addition to this internal double-rod gripper system, there is also an external double-rod gripper system, which is powered and moves forward and back to grasp the respective bag. The bag is then transported and released, whereby the interaction between the two double-rod gripper systems moves the respective bag forward.
- Some devices therefore turn to a complex solution that requires or desires a plurality of components. Furthermore, replacement of the grippers to retool the device for bags with a different exterior contour and/or different exterior dimensions is difficult and requires or desires time-consuming installation.
- Added to this is that with the double-rod gripper systems described above, the individual bags must or should be repeatedly released and regrasped. When processing liquid products and the filled bags, this can result in the filled product splashing outward. A potential consequence of this is that the gripper no longer holds the bag securely and the bag drops off under its own weight.
- But problems with the filling of such bags are not limited to liquid products; they also occur with dry products such as powders. This is generally due to the flexibility of the tubular bag and/or wrapping material, which results in imprecisions during grasping and the falling off of the bag.
- With small bags with tight tolerances or larger bags with small fill openings, the mode of operation described above with the two double-rod gripper systems can even result in the bags no longer being properly centered relative to the respective filling nozzles. This results in metering errors because the filling nozzles miss the middle of the bag and meter product beside the respective bag.
- Some devices for the treatment of flexible, tubular structures with at least one opening use a carousel equipped with grippers. A plurality of gripper pairs are provided over a relatively small diameter, which grippers hold and handle the bags at the two outer, vertical ends. As the radius of such machines increases, so does the speed of rotation, which results in very high centrifugal forces; these machines are thus limited with respect to transport speed. In addition, the generally small diameter of each carousel permits metering with at most two different metering devices or filling nozzles.
- In practice, however, there is an increasing demand for more than two feeds, and thus a plurality of metering devices or filling nozzles is desired. Instant soups in bags, for example, desire at least three, if not even four or more, metering devices that fill noodles, dried vegetables, croutons and the actual soup powder into each bag to make an instant soup. Consistent or optimum quality with the desired proportions of the respective components can be essentially ensured or promoted by means of the individual feeds described above. In this example, this presumes at least four metering devices are provided at or above the device in question for the treatment of flexible, tubular structures with at least one opening, which is not possible with these devices with a gripper-equipped carousel. The present application seeks to alleviate these issues.
- These devices therefore turn to a complex solution that requires or desires a plurality of components. Furthermore, replacement of the grippers to retool the device for different bags is difficult and requires or desires time-consuming installation.
- An object of the present application is to refine such a device for the treatment of flexible, tubular structures with at least one opening, for example bags, so as to enable simple and fast replacement of the gripper pairs and to provide sufficient space for the attachment of associated metering devices.
- To achieve this technical objective, the present application teaches a generic device wherein the leading gripper and the trailing gripper are mounted on separate guide trains that can be moved relative to one another.
- In addition and in accordance with at least one possible embodiment according to the present application, to achieve this technical objective, a generic device within the scope of the present application is wherein there is a controller provided that shifts the respective leading gripper by a certain amount in the direction of transport and the respective trailing gripper by the same amount opposite the direction of transport so that the bag middle retains its position even in the event of a bag change. In at least one embodiment, the grippers may be moved in relation to one another while both are moving in a direction of transport.
- According to the present application, the leading gripper is that gripper of a gripper pair that leads the gripper pair during the transport of a structure, whereas the trailing gripper follows the leading gripper and thus is the last gripper of the gripper pair relative to the direction of transport or the direction of travel of the grippers. The grippers can hold the respective structure or bag in any possible manner; for example, the grippers can be inserted into the opening, spreading the opening per frictional connection until the grippers rest against the walls of the bag. Of course, it is likewise within the scope of the present application if the grippers grab the respective bag or structure with clips, by suction, etc., typically with the leading gripper grabbing the front vertical end of the bag relative to the direction of transport or motion and the trailing gripper grabbing the corresponding rear vertical end.
- Also covered by the present application is the case in which the bags are gripped by their side edges rather than at the opening as shown in this possible embodiment.
- In detail, the two guide trains, which are moved relative to one another, are powered by a motor and independently of one another, whereby a separate drive for each guide train is in one possible embodiment to essentially ensure or promote the motion of the guide trains relative to one another described above.
- In addition, in detail, the two guide trains, which are stationary relative to one another, are powered by a motor and independently of one another, whereby a separate drive for each guide train is in one possible embodiment to essentially ensure or promote the motion of the guide trains relative to one another described above. By means of this motion relative to one another, the present application essentially ensures or promotes that bags of very different sizes and correspondingly variable openings and/or fill openings and contours can be processed. According to the present application, what is required or desired when changing from one type of bag to another is to engage the motors of the guide trains such that the leading gripper and the trailing gripper are moved the same distances, with the leading gripper moving in the direction of transport and the trailing gripper moving opposite the direction of transport. However, it is to be understood that both the leading and trailing grippers may be moving in a direction of transport at different speeds and be moved with respect to one another. Presuming that the bags are mirror-symmetric relative to a plane passing through the middle of the bag, this procedure essentially ensures or promotes that the middle of the bag and thus the plane of symmetry in question remain unchanged during this procedure. The present application thus essentially ensures or promotes in this manner that metering devices located relative to the middle of the respective bag continue to meter product into the middle of the bag, including with bags of different dimensions.
- The two guide trains are generally in the form of an endless loop and are also operated as such. Essentially, of course, two independently-driven endless loops are realized, because the two guide trains are laid out separately from one another. The guide trains themselves can have one or more conveying devices, such as belts, chains, etc., to which the leading grippers or trailing grippers are mounted separately and independently. In other words, the leading grippers are mounted on one guide train, the leading gripper train. The trailing grippers are likewise mounted on a single guide train, the trailing gripper train. As previously elucidated, both the leading gripper train and the trailing gripper train have their own motor drive and their own conveying devices.
- Both guide trains or gripper trains and their motors are connected to a common controller that is responsible for the motion of the grippers relative to one another. A path of motion defined by the two guide trains or gripper trains is linear over at least one segment of defined length. This segment of defined length accounts for the requirements arising from the desire or need to meter different products or components into the structure or the bag. The length of the linear segment is defined as a function of the number of metering units, which are generally arranged linearly and in series.
- Overall, the path of motion described by the two guide trains or gripper trains is an elongated circle. The two grippers are normally on the same side—the processing side—relative to the path of motion described by the guide trains. A front and a rear deflector for the grippers or the individual gripper pairs essentially ensure or promote that these continue to circulate around the elongated circular path.
- As previously elucidated, the distance between the two grippers relative to one another generally corresponds to the width of the bag to be processed or the width of its opening or fill opening. Once a gripper pair has secured the bag to be processed, the bag is not released until it has been completely processed, e.g., is filled to the required or desired level, has a label applied to it and possibly subjected to a dust extraction process. It is understood that the distance in question is stored in the aforementioned controller and can be called up when processing the bag in question. Other processing distances for the respective grippers are also stored in the controller.
- As soon as a bag change is performed, for example, this corresponds to a different processing distance between the grippers or between two gripper pairs, which is queried in the controller. The controller also essentially ensures or promotes that the two grippers of each gripper pair are moved apart in a reproducible manner, whereby it is also essentially ensured are promoted that a bag change does not result in a change in the respective bag middles. This essentially ensures or promotes that the bags are reproducibly centered under the corresponding metering unit with the middle of the bag in a fixed position. This enables the device to be retooled more or less by the push of a button in the event of a bag change, in that the processing distances corresponding to the new bags are queried in the controller and the controller also initiates the required or desired relative movement of the grippers of each gripper pair.
- In at least one possible embodiment according to the present application, the two guide trains/gripper trains are arranged above one another when viewed from the side. This allows the mounting of the two grippers on mounting plates, from which they extend. The mounting plates themselves are mounted on the guide trains or gripper trains arranged one above the other when viewed from the side.
- As described previously, the guide trains or gripper trains, and with them the leading gripper and the trailing gripper of each gripper pair, can be displaced relative to one another, in one possible embodiment by means of a motor, in that the motor of the leading gripper train and that of the trailing gripper train are actuated as specified by the controller for the respective bag. Of course, it is also possible and within the scope of the present application to manually adjust the guide trains or the gripper trains to adjust for a bag change. Both the manual and the motorized displacement of the gripper or guide trains relative to one another does more than make it possible to vary the distance between the grippers. The distance between the gripper pairs can also be selectively modified. This distance between the gripper pairs is also called the gripper pair gauge. Motorized and manual displacement can also be combined.
- With the ability to adjust the gripper pair gauge, the present application takes into account requirements saying that a larger bag can and must or should be filled with two instead of four metering devices as was the case previously, for example. In such a case, a larger gripper pair gauge than before is usually used and possibly the speed of the guide trains or gripper trains increased. Naturally, the opposite approach is also plausible.
- Because the grippers are in one possible embodiment non-permanently mounted on the guide trains or are non-permanently mounted on their corresponding mounting plates, the device according to the present application can be easily retooled with other grippers. This further increases the flexibility and enables the device described to be used for almost any application. Another option is to divide the leading gripper train, the trailing gripper train or both into segments, which can be assembled into modules. This requires or desires transition stations, e.g., from one leading gripper train to the next leading gripper train, and also synchronization of the motion. That can be accomplished by the common controller.
- The result is the provision of a device for the treatment of flexible, tubular structures with at least one opening, in one possible embodiment bags, with heretofore unknown flexibility. Indeed, very different bags or structures with varying openings or fill openings can be processed without the need or desire for any mechanical manipulation. Instead, the device is retooled essentially automatically in the event of a bag change by calling up the corresponding processing program in the controller. Finally, the grippers are simple to replace, thus easily facilitating various gripping applications.
- The above-discussed embodiments of the present invention will be described further herein below. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
- One possible embodiment of the present application is described in greater detail below illustrated with the accompanying drawings, in which:
-
FIG. 1 shows as perspective view of one section of the device according to the present application; -
FIG. 1A shows detail references of the perspective view of the section of the device shown inFIG. 1 ; -
FIG. 2 shows a side view of the device, partly in detail; -
FIG. 3 shows a side view during a bag change; and -
FIG. 4 is a block diagram showing a device according to the present application. - The figures show a device for the treatment of flexible, tubular structures with at least one opening that in this embodiment is suitable for the treatment of
bags 1, but is not restricted thereto. Processing of thebags 1 means, for example, filling them by means of ametering device 2. Alternatively or in addition, this could also mean the application of labels, an overprint, contours, the application or attachment of spouts, adapters, valves, etc. - The basic configuration of the device comprises at least one
gripper pair 3, 4, having a leadinggripper 3 and a trailing gripper 4. One sees that the possible embodiment includes a plurality of leadinggrippers 3 and trailing grippers 4. Eachbag 1 is secured and transported with the help of the associatedgripper pair 3, 4. Thegripper pair 3, 4 holds thebag 1 in question at its opening or fill opening. - In one possible embodiment according to the present application, the leading gripper or
grippers 3 and the trailing gripper or grippers 4 are mounted on different guide trains orgripper trains grippers 3 are mounted on a leadinggripper train 5, whereas, by way of exception, the trailing grippers 4 are mounted on a trailinggripper train 6 for the two guide trains orgripper trains - One sees that the leading
grippers 3 in the direction of transport or direction of motion R of eachgripper pair 3, 4 assumes a leading position, whereas the trailing grippers 4—as the name suggests—trail. So that the twoguide trains gripper train 5 on the one hand and the trailinggripper train 6 on the other. - The motorized drive 7 is a leading gripper train drive 7, which acts on the leading
gripper train 5, whereas motorized drive 8 is configured as a trailing gripper train drive 8 and impinges the trailinggripper train 6. Both the leading gripper train drive 7 and the trailing gripper train drive 8 are realized in the embodiment as, but are not restricted to, electronic servomotors and are connected to a common controller 9. - Both guide trains 5, 6, are in the form of an endless loop, which in the possible embodiment has the form of an elongated circle. The path of motion in direction R defined in this manner by the two guide trains or
gripper trains metering devices 2 in this example, each of which is arranged in a fixed location. - So that the
metering devices 2 and the associated processing points can fill thebags 1 without problems, it must or should be essentially ensured or promoted that the middle M of each bag or the center plane of the bag is positioned exactly or virtually exactly or generally below or above themetering devices 2 arranged along the path of motion as the bags circulate. By doing so, thebag 1 in this example can be processed or filled without problems even ifbags 1 of different sizes, variable shapes or which otherwise differ from one another are to be treated. - As shown in
FIG. 1A ,metering device 2 comprises an upper material holding portion 35, having a funnel configuration in the embodiment shown, and a lower exitingportion 28 depending downward from material holding portion 35.Bags 1 are disposed withgrippers 3 and 4 with the middle M of the opening inbag 1 substantially below exitingportion 28. The materials being metered intobag 1 may flow throughexit portion 29 by gravity into middle M ofbag 1 as shown bymaterial flow 29. - One sees that the two guide trains or
gripper trains guide trains grippers 3 and the trailing grippers 4 are mounted separately and independently on the said conveying devices; in one possible embodiment, the leadinggrippers 3 on the conveying device of the leadinggripper train 5 and the trailing grippers 4 on the respective conveying device of the trailinggripper train 6. - With the help of the controller 9, the distance A between the two
grippers 3, 4 can be varied, e.g. in that the leading gripper train drive 7 impinges the leadinggripper train 5 while the trailinggripper train 6 remains stationary. It is also possible to vary a distance B between the gripper pairs 3, 4. This distance B between the gripper pairs 3, 4 is also called the gripper pair gauge. By impinging the leading gripper train drive 7 on the one hand and the trailing gripper train drive 8 on the other, the controller can vary both the distance A between thegrippers 3, 4 and the distance B between the gripper pairs 3, 4, or the gripper gauge, as a function of the size of thebag 1 to be processed in the example and the number of components desired, and thus the number ofmetering devices 2 for filling thebag 1. - In the event of a bag change, as long as the
bags 1 are mirror-symmetric relative to a plane of symmetry running through the middle M of the bag (which is often the case), the controller 9 essentially ensures or promotes that the respectiveleading gripper 3 is shifted by a defined amount C in the direction of transport R, for example, and the corresponding trailing grippers 4 are moved by the same amount C in the direction opposite the direction of transport R. By means of this quasi symmetrical shift by the same amount C, the middle M of the bag retains its same position even in the event of a bag change, as is clearly illustrated inFIG. 3 fordifferent bags 1 or for the case of a bag change. - Thus a bag change is performed more or less at the push of a button, in that the corresponding processing distances A and/or B for the
respective bag 1 are queried in the controller and result in a corresponding actuation of the motors or drives 7, 8. In an embodiment, distances A and/or B may be changed with one or at least one motor arrangement. A motor arrangement may comprise a motor and one or more clutch arrangements, rods, cams, or other devices to change distances A and/or B. As is suggested inFIG. 2 , the gripper pair gauge can also be modified by the insertion of corresponding spacers. This means that the distances A and/or B can be adjusted both by motor and manually. This accounts forbags 1 of different shapes in the event of a bag change, and also essentially ensures or promotes that the position of the middles M of the bags relative to the guide trains 5, 6 and thus to themetering devices 2 remains unchanged. - The
grippers 3, 4 are mounted on mountingplates FIG. 1 . The leading mountingplates 11 holding the leadinggrippers 2 are logically mounted on the leadinggripper train 5. On the other hand, the trailing mountingplates 12 are mounted on the trailinggripper train 6. This can be done by bolting, riveting, etc. Thegrippers 3, 4 themselves are non-permanently attached to, and in this example suspended from, the respective guide trains orgripper trains plates - The leading
grippers 3 are mounted on conveyingdevice 5 and the trailing grippers 4 are mounted separately and independently on conveyingdevice 6 as shown inFIG. 1A . Specifically,grippers 3 are comprised of a leadingjaw 24 and a trailingjaw 23 depending from abase 25. Grippers 4 are comprised of a leadingjaw 44 and a trailingjaw 43 depending from abase 45.Base 25 is connected togripper train 6 with mountingplate 12.Base 45 is connected togripper train 5 such thatbases plate 11 is connected togripper train 5 and extends horizontally therefrom. Downwardly extendingarm 46 connects horizontally extendingarm 47 to mountingplate 11.Base 45 extends from extendingarm 47 towardbase 25. - Leading
jaw 24 and/or trailingjaw 23 may be movable with respect to one another such that gripper 4 operates to gripbag 1 proximate trailingupper edge 32. The jaw(s) 23 and/or 24 may be moved with an electro mechanical motor or electronic servomotor and may be controlled with controller 9.Grippers 3 and 4 may be electromagnetic and/or may have one or more cams to effectuate gripping. Leadingjaw 44 and/or trailingjaw 43 may be movable with respect to one another such thatgripper 3 operates to gripbag 1 proximate leadingupper edge 31. The jaw(s) 43 and/or 44 may be moved with an electro mechanical motor and may be controlled with controller 9. However, leadingjaw 24 and trailingjaw 23 may be biased toward one another wherein trailingside wall 34 ofbag 1 may haveupper edge 32 inserted therebetween. In a like manner, leadingjaw 44 and trailingjaw 43 may be biased toward one another wherein leadingside wall 33 ofbag 1 may haveupper edge 31 inserted therebetween. Such biasing may eliminate a need for a motor to gripbags 1.Jaws bag 1 to incorporate a tolerance in the position ofedge 32 andjaws gripper 3 may have a throw or distance therebetween when separated to receive a portion ofbag 1 to incorporate a tolerance in the position ofedge 31. It is to be understood thatgrippers 3 and 4 may be configured to gripedges FIG. 1A , and may also be configured to gripbag 1proximate seams bag 1 may not haveseams - For example, in an embodiment,
grippers 3 and 4 such as those disclosed FIG. 6 of U.S. Pat. No. 4,108,300, incorporated herein by reference in its entirety, may be incorporated into embodiments of the present application. As shown in FIG. 6 therein, “thebag gripping claws 11 are composed of parts 11a to 11g. A movable claw 11a moves about a pin 11d against a resilient force of a compression spring 11c, and a fixed claw 11b is fixedly mounted on a slide block 11f together with a roller 11g by means of a bolt 11e. The slide block 11f is slidably supported on a rod-shapedattachment 13 of thechain conveyor 12. Theempty bag 1 is gripped between the movable claw 11a and the fixed claw 11b by the resilient force of the compression spring 11c. Reference numerals 14 and 15 designate rails for guiding thechain conveyors 12, and numerals 16 and 17 designate guide rails for guiding the roller 11g. A pusher device 18 moves the grippingclaws 11 in accordance with the geometrical decrease of the size W of the bag in FIG. 2 which occurs when the top mouth of theempty bag 1 is opened. The pusher device 18 moves the grippingclaws 11 by moving the roller 11g and is integrally formed with a regulating table 19 which is integral with the rail 15. The piston rod of the pusher device 18 is adapted to be guided by the rail 15.” U.S. Pat. No. 4,108,300,column 2, lines 35 through 54. -
Gripper 3 may be mounted to abase 25 and may comprise a leadingjaw 23 and a trailingjaw 24. Gripper 4 may be mounted to abase 45 and may comprise a leadingjaw 44 and a trailingjaw 43. One or both of the leading and trailing jaws may be biased toward each other. - In a possible embodiment,
grippers 3 and 4 may have a configuration as disclosed U.S. Pat. No. 6,276,117, incorporated herein in its entirety. “Referring in greater detail to the clamps 60, 62 of the preferred embodiment with reference to FIGS. 13 through 15 illustrating an exemplary trailing clamp, it is seen that the trailing clamp includes a base 100 that mounts to the posts 94. The base 100 carries a pair of jaws 102, 104 which are pivotable relative to the base 100, via an arm 106. The jaws 102, 104 are pivotable relative to each other and biased towards each other by a spring clip 108 surrounding the jaws 102, 104. The movement of the jaws 102, 104 is controlled by two followers 110, 112 which are adapted to engage surfaces for actuating and controlling the position of the jaws 102, 104. A coil spring 114 biases the arm 106 towards a rest position. The inside jaw 102 is fixed to the arm 106 while the outside jaw 104 is movable with respect thereto. Upon proper actuation of the first follower 110, the outside jaw 104 is urged away from the inside jaw 102 against the action of the spring clip 108 such that the jaws 102, 104 are opened to a pick position as shown in FIG. 16 to receive an edge of a pouch therein. The pick position is utilized at the pick station 34 (FIGS. 5 through 9) to pick new unfilled pouches from a pouch supply. Once the edge of the pouch is between the opened jaws 102, 104, the first follower 110 is released to allow the spring clip 108 to close the jaws 102, 104 and pinch the pouch edge therebetween. At this point the pouch is closed. To assist in opening the pouch by providing slack in the pouch, the second follower 112 is actuated against the action of the coil spring 114 which pushes the arm 106 and the pair of jaws 102, 104 forward toward the leading clamp 60 as shown in FIG. 17. This shortens the distance between leading and trailing clamps 60, 62 and provides sufficient slack in the pouch such that the pouch remains open for filling operations (see reference number 36 in FIG. 5). Turning to further details of the leading clamp 60, it includes a base member 120 mounted to the mounting posts 94. The base member 120 projects beyond the periphery of the chain guides 76, 78 to support an upright arm 122 which projects vertically to the elevation at which the jaws 102, 104 of the trailing clamp 62 are located. Near the top end of the arm 122 at a similar elevation as the jaws 102 104, resilient clips 124 are provided which are adapted to be opened to receive an edge of a pouch and closed to pinch the pouch in order to hold the edge of the pouch. The leading clamp 60 works cooperatively with the trailing clamp 62 to support a pouch.” U.S. Pat. No. 6,276,117, column 7,lines 6 through 49. - Comparing
FIG. 1 andFIG. 3 , one recognizes that the twogrippers 3, 4 are on the same side, theprocessing side 13, relative to the path of motion defined by the guide trains orgripper trains metering devices 2 can be arranged linearly and in series one behind the other above the path of motion on thisprocessing side 13, and the guide trains 5, 6 are largely protected against any fouling during metering. The linear course of the path of motion in the affected segment T also facilitates this arrangement. In fact, themetering devices 2 and the guide trains 5, 6 are aligned and in parallel or are aligned virtually parallel to one another, at least in this segment T. - Finally,
FIG. 2 suggests that the two guide trains orgripper trains gripper trains bags 1 can be processed simultaneously or substantially simultaneously. Of course, it also lies within the scope of the present application to place additional guide trains withcorresponding grippers 3, 4 either above or below the twoguide trains -
Bag 1 may haveseams panels panels Bag 1 may be tubular and may be without seams.Bag 1 may have only one seam or may have any plurality of seams.Bag 1 has an open top and at least substantially closed sides and bottom.Bag 1 may be comprised of a clear, see through, or opaque plastic material, a metallized material, or other materials as are known in the art for containing fill materials such as bulk goods. - Prior to
bag 1 being gripped withgrippers 3 and 4, whether being grippedproximate seams seams bag 1,bag 1 needs to be opened.Bag 1 is opened with an apparatus configured to open bags as in known by one of ordinary skill in the art. For example, in one embodiment,bags 1 may be opened with an apparatus similar to that disclosed in FIG. 4 of U.S. Pat. No. 4,108,300. “Reference numerals bag 1 for purpose of charging thebag 1 with the contents. The vacuum suction cups are mounted on levers 21, 21, which are in turn rockable about a fulcrum on a support shaft 22 in accordance with the opening state of thebag 1. The support shaft 22 is supported from the main body 8 in a vertically slidable manner, and thevacuum suction cups 20 are so composed that the vertical movement and the bag opening operation may be effected thereby. The grippingclaws 11 are mounted on the rod-shapedattachment 13 of thechain conveyor 12 at a fixed pitch, and thechain conveyor 12 is conveyed by adrive sprocket 23 in the direction of advance as indicated by an arrow in FIG. 3, the conveying distance (one pitch being equal to P (FIG. 3)). The movement of thechain conveyors 12 is intermittent, and in the illustrated positions they are stopped. Thedrive sprocket 23 is rotated through ashaft 25 by anindexing device 24, while the input shaft of theindexing device 24 is connected via coupling means 27 to a power source such as a motor 26 or the like supported from the main body frame. U.S. Pat. No. 4,108,300,column 2,line 55 throughcolumn 3, line 8. - In an embodiment, the opening of
bag 1 may be processed with a device similar to that disclosed in U.S. Pat. No. 6,276,117. “FIGS. 5 through 6 schematically illustrating the preferred embodiment, theendless carrier 28 generally picks up newly formed or otherwise supplied pouches at apick station 34, opens the pouches at an opening station 35 (which includes a clamp distance shortening station 36 and a wedge forming station 37), fills the pouches with the desired material at a fill station 38, seals or otherwise closes the pouches at a closing station 39, seals the pouches at a seal station 40 and drops off the sealed and filled pouches at a drop station 42.” U.S. Pat. No. 6,276,117, column 4,lines 33 through 42. “To also maintain high rates of production, the sequence or configuration of the stations may also be changed. For example, vacuum machinery which pulls the sides of the pouches at the filling station 38 may be removed and replaced with a wedge opening station 37 located upstream of the filling station. A partly schematic illustration of the machinery used at the wedge opening station 37 is shown in FIG. 20. The machinery includes a bracket 156 which mounts on the support frame 26 that carries a wedge carriage 158 which includes a wedge 160 for forming a pocket in the pouch 22 prior to filling as schematically indicated by reference numeral 37 in FIG. 5. The carriage 158 is slidable and linearly translatable on guide rods 162 to move into and out of pouches. The carriage 158 is driven by thecycle shaft 33 in a conventional cycle such that the wedge 160 is driven into the pouch during the dwell time to form an opening or pocket therein. By eliminating the vacuuming step at the fill station 38, the minimum required dwell time is reduced thereby allowing for an increase in packaging production.” U.S. Pat. No. 6,276,117, column 9,lines 3 through 21. - An embodiment of an apparatus for filling bags as disclosed herein may comprise a
first guide train 5 and asecond guide train 6, each having a portion movable in a substantially parallel orientation. Afirst gripper 3 is disposed with thefirst guide train 5 and a second gripper 4 is disposed with thesecond guide train 6. Prior tobags 1 being gripped withgrippers 3 and 4, they are opened and disposed for gripping. For example, a continuous roll ofbags 1 may be unrolled, cut to separate intoindividual bags 1, opened, and placed with a portion between each pair jaws ofgrippers 3 and 4. The bags may be opened by any means as is known in the art. For example, in an embodiment whereinbags 1 haveseams bags 1 may be grippedproximate seams bag 1, using vacuum grippers on the sides ofbag 1, or by inserting a wedge intobag 1. In an embodiment whereinbags 1 do not have seams, opening may be effectuated with vacuum, for example. Theopen bags 1 may then be positioned withingrippers 3 and 4 for gripping with an arrangement configured to positionbags 1 for gripping withgrippers 3 and 4. - In an embodiment,
jaws jaws gripper 5 are separated by a sufficient throw or distance to incorporate tolerances in the positions of portions ofbags 1 to be gripped. For example,jaw 23 of gripper 4 andjaw 43 ofgripper 3 may both be extended by an amountsuch jaws bag 1. At the same time,jaw 24 of gripper 4 andjaw 44 ofgripper 3 are moved in a direction away from the middle of the opening M ofbag 1. - An embodiment having an arrangement configured to position
bags 1 may be incorporated withguide trains bags 1 and position a portion betweenjaws jaws bags 1 betweenjaws jaws Bags 1 may be positioned withingrippers 3 and 4 having an opening orthogonal, parallel, or oblique with the direction R ofguide trains - The positioning of the portions of
bag 1 to be gripped withgrippers 3 and 4, whether the portions beseams upper edges panels bags 1, the positioning of portions ofbag 1, the gripping ofbags 1, and/or positioning of the middle M with respect tometering device 2 ofbags 1. The data gathered by the optical sensors may be relayed to controller 9. Controller 9 may then relay commands to change positioning ofbag 1, discardbag 1, suspend metering and/or change other or different processing parameters. -
FIG. 4 shows a block diagram of at least one embodiment of the present application. Flexibly sided containers are fed at 50 to anarrangement 51 configured to open and dispose flexibly sided containers.Arrangement 51 may have grippers or may have vacuum or suction apparatuses, or may use other means as are known in the art to open and dispose flexibly sided containers for gripping.Arrangement 51 may be a part of fillingapparatus 53 or may be a separate apparatus. Flexibly sided containers are fed at 52 to a fillingstation 53. Fillingstation 53 is configured to fill flexibly sided containers by first gripping and then disposing the flexibly sided containers under a filling apparatus.Gripping arrangements 54 are opened and closed to grip portions of flexibly sided containers with an activatingdevice 55 configured to open and close thegripping arrangements 54. Activatingdevice 55 may comprise one or more electromagnetic motors, cams, rods, or other devices as are known in the art to move the jaws of the grippers ofgripping arrangements 54 together for gripping and apart for releasing portions of flexibly sided containers. For example, each jaw of a gripper, each gripper, each pair of grippers, or a plurality of pairs of grippers may have an electromagnetic motor in communication therewith to effectuate gripping and releasing of flexibly sided bags withgripping arrangements 54, The flexibly sided containers are gripped and opened withgripping arrangements 54 and moved under a filling apparatus where they are filled with filling materials. The filling materials may include food items such as candies, for example gummy bears or jelly beans, snack items, for example pretzels or potato chips, or other food items. However, the flexibly sided containers may be filled with any liquid or solid materials such as bulk goods. The flexibly sided containers may be moved with one or more conveying arrangements. The conveying arrangements may be linear or in a loop configuration. The conveying arrangements may be moved with one ormore motor arrangements 59. After filling, the flexibly sided containers are moved from fillingstation 53 at 56 where they may be further processed, for example closed, labeled, etc., atprocessing station 57. For example, the flexibly sided containers may be reclosable bags that are closed with the application of pressure to each side of the closing structure atprocessing station 57. In an embodiment, the flexibly sided bags may be welded shut with the application of heat or otherwise thermally sealed, ultrasonically bonded, or otherwise closed by other means as is known in the art. For example, flexibly sided containers may be closed with an apparatus such as the device disclosed in United States Patent Application No. 2007/0101684, incorporated herein by reference in its entirety. Filled flexible containers exit the arrangement at 58. - An object of the present application is a device for the treatment of flexible, tubular structures with at least one opening, for
