Ring, Downey, Calif., assignor to The Coca- Coia Company, Atlanta, 62., a corporation of Delaware Filed Aug. 25, 1966, Ser. No. 575,118 13 Claims. (Cl. 198-31) ABSTRACT OF THE DISCLOSURE The container separator guides a predetermined number of containers from a row onto retractable rails, detects the presence of each container of the number in a respective position, and retracts the rails to dispense the number of containers simultaneously under gravity. Maintenance of the correct number of containers in successive rows is assured for proper packaging.
This invention relates to an automatic container separator. More particularly, this invention relates to an automatic container separator for separating a single row of delivered containers into a plurality of aligned rows of dispensed containers. Still more particularly, this invention relates to an automatic container separator for separating a single row of containers into a plurality of aligned rows in preparation for case packing.
Generally, in packaging content filled containers, the containers are automatically conveyed in a single continuous row into a separating device for segregating successive containers into different runways. The runways are aligned with each other to guide the segregated containers in aligned rows into case packing units wherein the aligned rows of containers are placed in suitable cases for shipment.
Heretofore, container separating devices have been used which direct each container of a delivered row of containers into a different runway from the next successive container. In some instances, these separating devices have utilized a rotary wheel provided with circumferential container receiving pockets and releasable container locks in each pocket which sequentially lock a received container in place and release the container after a predetermined rotation of the wheel for depositing successive containers into differently spaced runways. In other instances, the separating devices have utilized a pair of tangentially disposed rotors in the path of the containers which have ditferent sized container receiving peripheral pockets. The rotors have coacted together to segregate successive containers into disparate runways having particularly shaped entrances.
However, the heretofore used separating devices have not been generally successful in that the containers have not always been delivered into the proper runways. That is, the topmost runways have had more containers than the runways below, and in some instances, the lowermost runway has been void of any containers. This has caused an uneven distribution of the containers per row to be introduced into the case packing units and thereby has caused malfunctioning of the case packing units and coincident delays in output. Further, the separating devices have had frequent malfunctions in dispensing the containers into the runways which have caused jams and production down time. Additionally, especially where spring tensioned mechanisms have been used, the general method of operating the separatingdevioes has made adjustments very difi'icult.
Generally, the invention provides an automatic container separator which separates a single row of delivered containers into a plurality of runways by intermittently segregating a predetermined number of containers from "ice the delivered row of containers and depositing the segregated containers into the runways simultaneously. The automatic containers separator is positioned in the path of a row of moving containers at the entrance to a con veyor ramp having a plurality of runways. The separator includes a housing having a guide means for positioning a row of containers in the separator and a pair of oppositely mounted retractable rails mounted over the run-" ways for receiving the containers, a stop for abutting the foremost container, means for detecting the presence of a predetermined number of containers on the retractable rails and means for actuating the retractable rails to retract and close. In addition, the separator has a means positioned adjacent the runways for determining the passage of a predetermined number of containers from the retractable rails in order to reset the rail actuating means and container detecting means.
When the means for detecting the presenc of a predetermined number of containers on the retractable rails over the runways is actuated, the rails are retracted to allow the containers to fall simultaneously under gravity into the respective runways. Upon passing the means adjacent the runways for determining the passage of the segregated containers, the falling containers actuate the means to close the rails and to reset the means for detecting the presence of containers thereon.
In order to prevent the movement of succeeding containers into the separator, a stop arm is provided in the path of the single row of containers which is actuated simultaneously with the retractable rails.
The invention provides a method of separating a single row of containers into a plurality of aligned rows which includes the steps of moving the row of containers in a downwardly sloped direction, arresting movement of the containers, segregating a predetermined number of the foremost containers and dispensing the segregated containers simultaneously under gravity in aligned rows. The several steps are repeated in sequential manner so that the aligned rows of dispensed containers contain an even distribution of containers.
Accordingly, it is an object of the invention to provide an automatic container separator and method of separating a row of containers which segregates a plurality of containers from the row and delivers the segregated containers simultaneously into a plurality of runways for case packaging.
It is another object of this invention to provide an automatic container separator and method of separating a single row of containers which intermittently segregates a predetermined number of containers from the row and delivers the segregated containers simultaneously into a plurality of runways for case packaging.
It is another object of the invention to provide an automatic container separator which operates in response to the presence of a predetermined number of containers therein.
It is another object of the invention to provide an automatic container separator which is cycled by the passage of a predetermined number of segregated containers therethrough.
It is another object of the invention to provide an automatic container separator which operates in an efficient consistent accurate manner to intermittently deliver a plurality of containers into respective runways for a case packing unit.
It is another object of the invention to provide an automatic container separator which is easily adjusted and repaired.
It is another object of the invention to provide an automatic container separator with a sensing means for detecting any interruption in the delivery of containers.
It is another object of the invention to provide an automatic container. separator which avoids jamming of the containers with a resultant efficiency in running time.
These and other objects and advantages of the invention will become more apparent from the following detailed description and appended claims taken in conjunction with the accompanying drawings in which:

The containers 13 are initially fed into the supply ramp 11 in a continuously moving manner and are generally of a cylindrical shape. The supply ramp 11 is sloped downwardly so that the containers 13 roll substantially under gravity into the container separator 10. Similarly, the case packer runways 12 are sloped downwardly so that the containers 13, 13", 13" roll under gravity.
The automatic container separator 10 includes a pair of spaced opposed side walls 14 positioned astride the path of the single row of containers 13 contiguous to the respective ends of the ramps 11 and runways 12.

That is, each side wall 14 has a fixed lower rail 15 and a fixed upper rail 16 directed in a sloped downward direction in alignment with the supply ramp 11 for. guiding the containers 13 into the separator 10 and maintaining the guided containers against upward movement relative to the rails 15, 16. In addition, each side wall 14 has a retractable lower rail 17 in alignment with the fixed lower rail 15 below a forward portion of the upper rail 16. The forward end of the upper rail 16 is provided with a stop lug 18 which projects into the separator for arresting movement of the containers 13 down the rails 15, 17. The respective rails 15, 16, 17 of each side wall 14 are in horizontal alignment with each other so as to define a continuous passage with the supply ramp 11 for the single row of containers 13.
The lower rails 15, 17 are sized relative to each other so that a predetermined number of the containers 13 within the separator 10, for example, three, are supported on the retractable rails 17.
Further, the automatic container separator 10 includes a plurality of arcuate rails 19 mounted on opposed side walls 14 below the retractable rails 17 to form a plurality of arcuate chutes conforming to the number of containers positionable on the retractable rails 17. Each pair of horizontally opposed arcuate rails 19 is positioned relative to the retractable rails 17 and the runways 12 of the case packer to define a continuous arcuate passageway for a container 13 in passing from the separator 10 into the runways 12.
The container separator 10 is secured to the supply ramp 11 by a bracket 20 which passes under the supply ramp 11 and which is mounted on a rod 21 passing through and secured to the side walls 14. Also, the container separator 10 is secured to the case packer runways 12 through brackets 22 which are disposed across the undersidcs of the runways 12 and secured to angle irons 23 on the exterior surfaces of the side walls 14. Additionally, a lower adjustable framework 24 which is a part of a total conveyor machine structure supports the container separator 10.
Referring to FIGS. 1, 2 and 5, each retractable rail 17 is sized to project into the space between the side walls 14 a distance which is only sufiicient to adequately support the ends of the containers 13 without interfering with the downward movement of the containers upon retraction of the rails 17. Since the retractable rails 17 are actuated by identical assemblies only one of such assemblies will be described below in detail while the other assembly will be designated by primed reference characters in the drawings. Each retractable rail 17 passes through a slot 24 in the respective side wall 14 and is secured outside of the side wall 14 to the ends ofa pair ofspaced rods 25, as by welding. The rods 25 are each fixed to a shaft 26 which is rotatably mounted within a pair of spaced bearing blocks 27, 27'. The shaft 26 is rotated within the bearing blocks 27, 27 through an arm 28 which is fixedly secured at one end to the shaft 26 intermediately of the bearing blocks and pivotally secured at the other end to a piston rod 29 which passes through an aperture in the side wall 14 into an air cylinder 30. The air cylinder 30 is pivotally mounted on a pin support 31 secured to the side wall 14 opposite the side wall through which the piston rod 29 passes.
Referring to FIGS. 1 and 5, the air cylinders 30' for the two retractable rails 17 are operatively connected to a common airsupply source (not shown) for reciprocal,
movement of the respective piston rods 29. The air supply source delivers air in a conventional manner through an oiler 31a, a pressure regulator 32, and air filter 33 and a solenoid valve 34. The solenoid valve 34 (FIG. 5) is connected by a single air feed tube 35 having branches 35a and 35b to the respective forward ends of the cylinders 30, 30 for passing air into the cylinders 30, 30' to move the piston arms 29, 29" into the cylinders. Also, the solenoid valve 34 is connected by a single air feed tube 36 having branches 36a and 36b to the respective rear ends of the cylinders 30, 30' for passing air thereinto to move the piston arms 29, 29 out of'the cylinders.
Referring to FIGS. 1, 2 and 6, a container stop assembly 37 is mounted in the container separator 10 to prevent movement of the single row of containers from the fixed lower rails 15 towards the retractable rails 17 until the retractablerails 17 are within the confines of the side walls 14 and positioned to support containers thereon. The container stop assembly 37 includes a stop arm 38 pivotally mounted on a shaft 39 mounted between the side walls 14. The stop arm 38 is formed with a depending lug 40 at the shaft 39 which is engaged by a tension spring 41 mounted on the bracket rod 21 to constantly urge the stop arm in a downward direction into the path of the single row of containers 13. The stop arm 38 is formed with a bracket 42 intermediately on the top surface which secures one end of a flexible connection, such as a chain 43, therein. The opposite end of the chain is secured to a lever arm 44 transverse to the stop arm 38 which passes through one of the side walls 14 and which is fixedly mounted to shaft 26'. The connection of the lever arm 44 to the shaft 26' is such that the movement of the lever arm 44 is synchronized to the movement of the retractable rails so that upon rotation of the shaft 26 in a counterclockwise direction as viewed in FIG. 6, the stop arm 38 is pivotedagainst the force of the spring 41 out of the plane of the single row of containers 13 and the retractable rails 17 are pivoted into the confines of the sidewalls 14. This permits passage of the single row of containers onto the retractable rails 17. Conversely, upon rotation of the shaft 26' in a clockwise direction, the retractable rails 17 are moved out of the side walls 14 and the stop arm is moved under the force of the spring 41 into the plane of the single row of containers to prevent further movement onto the retractable rails 17 Referring to FIGS. 2 and 3, a container sensing assembly 45 is positioned in the container separator to detect the presence of a predetermined number of segregated containers on the retractable rails 17 and to determine the passage of the segregated containers through the chutes formed by the arcuate rails 19. The container sensing assembly 45 includes a purality of microswitches 46 corresponding to the number of containers to be positioned on the retractable steps 17, for example, three, which are secured along one of the upper rails 16 (FIG. 5) as by brackets 47. Each microswitch 46 has a finger 48 which projects into the path of the containers 13. The fingers 48 are each arranged to contact a container positioned over a chute defined by the rails 19 and thus actuate the respective microswitches upon the presence of a container. Additionally, the container sensing assembly 45 includes a microswitch 49 positioned adjacent one of the outer arcuate rails 19 having a finger 50 which project into the path formed by that rail and the next arcuate rail 19. The finger 50 is sized to contact one of the segregated containers to activate the microswitch 49 upon passage of the segragated containers through the chutes formed by the arcuate rails 19.
Referring to FIGS. 3 and 4, in operation, a single row of containers 13 are fed at a substantially constant rate into and down the supply ramp 11. The containers pass into the aligned passage of the automatic container separator 10 formed by the rails 15, 16, 17. With the retractable rails in a closed position (FIG. 3), the foremost con tainer 13' on the retractable rails 17 comes into abutting contact with the stop lugs 18 over the chute between the first pair of arcuate rails 19 and at the same time contacts the foremost microswitch finger 48 to actuate the microswitch. Subsequently, the succeeding containers on the retractable rails 17 come into mutual contact with each other over the chutes between the remaining arcuate rails 19 while simultaneously actuating the remaining microswitches 46 through contact with the finger 48. After three containers have come onto the retractable rails 17 and have actuated the three microswitches 46 simultaneously, a circuit is completed that actuates the solenoid valve 34 (FIG. 1) to introduce air through the air feed tube 35 into the air cylinders 30, 30' so as to move the piston arms 29, 29' into the cylinders. Upon movement of the piston arms 29, 29 (FIG. 5), the shafts 26, 26' rotate respectively to retract the retractable rails 17 from within the side walls 14 and to simultaneously drop the stop arm 38 into the path of the containers between the third container 13 and the next succeeding container to segregate the forward three containers.
The foremost three containers 13', 13", 13", because the lower support rails 17 are removed, drop into the chutes between the arcuate rails 19 under gravity. Since the stop arm 38 is in abutment with the foremost container of the containers remaining in the single row, there is no further movement of the containers from the lower fixed rails towards the retractable rails 17 As the segregated containers 13', 13", 13" continue through the chutes formed by the rails 19, one of the containers triggers the microswitch finger 50 to actuate the microswitch 48. This completes a circuit which recycles the microswitches 47 and reverses the solenoid valve 34 so that air is introduced through the air feed tube 36 into the air cylinders 39, 30' so as to move the piston arms 29, 29' out of the cylinders. The shafts 26, 26' are thus rotated to return the retractable rails 17 inside the side walls and to simultaneously lift the stop arm 38 from the path of the single row of containers. The next succeeding three containers roll into the retractable rails 17 to repeat the above operation.
When the segregated containers 13', 13", 13" reach the end of the arcuate rail chutes they are dispensed into the respective separated runways 12. The segregated containers then proceed to roll down the runways 12 in substantial alignment with each other to a conventional casepacker unit (not shown).
Should one or more containers fail to be positioned on the retractable rails 17 over the chutes formed by the arcuate rails 19, the microswitches 46 at those stations will not be actuated. Thus, the circuit for actuating the air cylinders to retract the rails 17 will not be completed. Accordingly, none of the containers will be allowed to drop through the arcuate rail chutes to the runways 12 of the case packer. The automatic container separator 10 operates to segregate and dispense the containers 13 only when a full complement of containers are positioned on the retractable rails 17 over the arcuate r-ail chutes.
Referring to FIGS. 1 and 7, an electrical circuit for coordinating the operation of the sensing assembly 45 and solenoid valve 34 includes a transformer 51 which is operatively connected to a relay 52 to transform a relatively high voltage e.g. volts, to a relatively low voltage, e.g. 24 volts. The relay 52 is operatively connected through lines 53, 54 to the microswitches 46 which are normally open. The microswitches 46 are connected in series through a line 55 to the microswitches 49 which is normally closed. The microswitch 49 is connected through a line 56 to a coil 57 of the relay 52. The coil 57 is operatively connected to the solenoid valve 34 through lines 58, 59. Thus, when the microswitches close, the circuit to the solenoid valve 34 is closed to direct air into the air cylinders 30 to retract the retractable rails 17. Upon opening of the microswitch 49, the circuit to the solenoid valve 34 is opened to redirect air into the air cylinders 30 to close the rails 17 and open the microswitches 46.
In order to provide for manual operation of the container separator 10, a push button release 60 is interposed in the circuit. The push button release 60 which is normally open is connected to the relay through lines 61, 62 and to the limit switch 49 through a line 63 from the relay 52. Upon closing of the button 60, a circuit is completed to the solenoid valve 34 to direct air into the air cylinders 30 to retract the retractable rails 17.
The transformer 51 and relay 52 as well as other suitable electrical components are housed within a box 64 mounted on one of the side walls 14 of the separator 10 (FIG. 1).
It is noted that the container separator may be readily modified to dispense any suitable number of rows of dispensed containers by adding or removing microswitches 46 and rails 19 with concurrent changes in the proportions of the separator components especially the retractable rails.
It is further noted that the containers while described above as being filled and of a cylindrical shape may also be unfilled and be of any size or volume as used in the conventional canning industry. Further, the containers may be made of glass, plastic, metal or any conventional canning material.
It is also noted that While the segregated containers are dispensed in intermittent fashion from the container separator the operation of the container separator is rapid and continuous so that delivery of the constant supply of the single row of containers is not significantly disrupted.
The invention provides a simple, efiicient conta'ner separator which automatically segregates a single row of moving containers into a plurality of aligned rows of containers and dispenses the segregated containers simultaneously into aligned case packer ramps. The container separator operates only upon the presence of a predetermined number of segregated containers over the respective ramps so that the containers are dispensed uniformly and evenly into the respective ramps of the case packer unit. Additionally, the container separator is constructed to be capable of rapid adjustments and repairs.
7 The container separator automatically segregates and dispenses containers at a high output rate with a substantial reduction in production down time.
Having thus described the invention, it is not intended that it be so limited as changes may be readily made therein without departing from the scope of the invention. Accordingly, it is intended that the subject matter described above and shown in the drawings be interpreted as illustrative and not in a limiting sense.
