Abstract

Device for fastening web-, plate- and/or profile-type components to a solid substructure. A strip-shaped backing element (5) is supplied from a supply magazine (4) through a guide element (6) to the lower side of the device. The strip-shaped backing element (5) therefore already lies below the screw axis so that the screws (9), which are also supplied from a magazine, can be screwed with the screwing device through the backing element into a solid substructure. The strip-shaped backing element (5) is wound onto a roll (166) from which it is wound off as the work proceeds.

Description

Device for fastening sheet, slat and / or profile-like components to a solid substructure

The invention relates to a device for fastening sheet, plate and / or profile-like components to a solid substructure with an arrangement for feeding and setting fasteners in an at least approximately perpendicular to the surface of the components to be fastened screw or setting axis.

Such devices have already become known in various versions. In such a known device for fastening panels made of insulating material (DE-A-2631841), channels are provided for the individual feeding of washers and screws. The washers and screws can be fed into the necessary position aligned with the screw axis via these channels. The handling with such an individual feeder is very cumbersome and therefore time-consuming.

In another known embodiment (EP-B-3004) there is also a feed shaft for the screws and an insertion path for the washers, but the screws are held in a supply strip or magazine and the washers are stacked in a magazine . Depending on the displacement movement of the screwing device, washers and screws are provided in the screwing axis by appropriate slides, slides, levers, grippers or the like. As only individual washers, stacked parts can be used in a ^• such a configuration.

The object of the present invention is to create a device of the type mentioned at the outset, with which a wide variety of shapes and configurations of support elements can be processed. Erfindungsge AESS this is achieved in that the bottom ar de ^v - -r "- direction of the axis or set of adjacent bereic 'egg t-EADERSHIP bzi- element of the screw for feeding a streifenför strength Unterlegelementer .. with a Unterlegelementen equipped strip provided where: a. guide element is formed from webs encompassing the edge region of the strip-shaped underlay element or band on at least part of its length, and that a storage magazine for the rolled-up or folded recording of an endless, strip-shaped bottom element or A band or a plurality of strip-shaped underlay elements or benches stacked one above the other or layered next to one another is provided.

By means of these measures according to the invention, only individual washers, but also strip-shaped washers, can be fed to the device for processing. Such strip-shaped Unte ^"- legelemente then run similarly to a continuous seam screwed on to be¬-setting portion, at certain intervals einge¬ fastening means or to be set. In the manner according to the invention, however, it is also possible to arrange individual washers on a belt for the purpose of pre-magazination, which can then be fed to the underside of the device for processing. However, precisely these measures according to the invention have also made it possible to connect individual washers in one piece in succession during production via individual webs or by means of band-like webs, in which case the individual washers can then be separated from one another if necessary.

Due to the inventive measures is achieved that a relatively large area can be covered in mounting of components with a unique ^r magazining the device before turn eir reloading with fasteners and Unterlegelementen becomes necessary.

It is advantageous in this case that the feeding of the strip-shaped underlay element or the band equipped with underlay elements can be changed depending on the work involved or takes place in a certain direction from the outset. It is therefore envisaged that the freely emitting range of the guide element in the displacement or Fe ^ direction de * device or at an acute angle or at right angles to this is aj- ^ri z * - tet.

For trouble-free feeding of the strip-shaped underlay elements? To ensure or band, it is proposed that the guide element is guided from the area adjacent to the screw or setting axis on the underside of the device into the area of the supply magazine.

In order to keep the risk of contamination of the guideways as low as possible on the rather rough construction site operation, provision is made. that the guide element is designed at least over part of its length as a closed channel which is approximately matched to the cross section of the strip-shaped underlay element or the band fitted with underlay elements.

If the storage magazine is designed as a rotatably mounted roll on which the endless, strip-shaped underlay element or tape is wound, then an optimal solution can be achieved with a very simple design, for example, only the entire rolls need to be replaced. It is thus possible to deliver rolled-up, strip-shaped underlay elements or rolled-up tapes equipped with underlay elements to the construction site.

Furthermore, it is provided that the storage magazine for the strip-shaped underlay element or band is arranged in front of the screwing or setting axis when viewed in the direction of displacement or travel of the device. This makes it possible, on the one hand, to continuously monitor the storage magazine and, on the other hand, makes continuous unwinding and application to the surface of the components to be fastened possible in the case of endless, strip-shaped support elements.

For most types of fastening for fastening sheet, plate and / or profile-like components to a solid substructure, it is mandatory to set fasteners at certain intervals, in this case it is advantageous if the strip-shaped fault-laying element is provided with prefabricated holes which are -oabg & r- at a certain grid spacing.

The strip-shaped underlay element can, however, also be made from individual, large-area washers made of plastic or metal, which are connected to one another via ^v -strip or cord-like supporting parts. It is therefore also possible in a simple manner to store such large-area washers in a rolled-up form with the device according to the invention.

In this context, it is also advantageous if the strip-shaped band is equipped with large-area washers made of plastic or metal which follow one another at a constant distance. It is also possible to provide the possibility of arranging the washers on the belt at the spacing provided for the fastening spacing or ^, however, in relatively close succession, the belt then being cut off between two successive washers.

To further improve the device according to the invention, it is expedient if a cutting device for severing the strip-shaped underlay element or band is assigned to the end region of the guide element. The strip-shaped washer element can then be separated at the required point, or individual successive sections of strip-shaped washer elements can be formed or individual consecutive washers can be separated from one another.

If a strip-shaped underlay element is placed continuously on the component to be fastened, then the advance is already given by the movement of the device. However, if the strip-shaped underlay element has to be separated for single or multiple attachments, then it is advantageous if a mechanical feed device for the strip-shaped underlay element is provided in the region of the guide element. In order to achieve optimum automation in the device according to the invention, with which the fastening means are also automatically fed, it is particularly advantageous if the feed device and or the cutting device are dependent on the travel movement of the device and / or the lifting movement of the screw or Is set operable.

Further features according to the invention and special advantages are explained in more detail in the following description with reference to the drawings. Show it:

6 to 9 different design variants of strip-shaped underlay elements or tapes equipped with underlay elements.

In Fig. 1 the device is shown in a known structure with the additional device according to the invention. It can be seen that the device consists of a housing 1 accommodating the entire movement unit, the structure 2, the mobile base 3, a storage magazine 4 for a strip-shaped base element 5 and a guide element 6. A screwdriver 7, for example, serves as the drive for the screwing device. The feed is held by a control rod 8, which at the same time assumes a management function. To feed screws 9 which are held in a supply strip 10, levers or the like which are not apparent from this FIG. 1 and which can be actuated as a function of the displacement movement of the screw device are used. The screws 9 are stored together with the magazine belt 10 in a pot-shaped storage container 11 and can be pre-stored there in roll form. Of course it is all-ed * - other magazine storage of screws is possible. In the known device, a storage magazine 12 is also provided for large flat washers, which are kept stacked one above the other and are fed into the area below the screw axis by slides or slides, which can be moved depending on the displacement movement of the screwing device become. The supply magazine 4 for the strip-shaped support element 5 and the guide element 5 can be attached to an existing screwing device as an additional device, or such a supply magazine 4 is permanently mounted on the device. In the first case, a device according to the invention can be used both in the conventional manner with the stacking of washers 12 and with a strip-shaped washer element supplied.

A device was explained with reference to FIG. 1, which can be used for screwing in screws together with washers or with strip-shaped washer elements. However, the measures according to the invention can also be used if, instead of screws, other fastening means are used which are anchored in any form by screwing in or driving in the fixed substructure.

The guide element 6 is provided on the underside of the device and is used to feed a strip-shaped underlay element 5 or a band equipped with underlay elements into the area below the screw or setting axis. On the storage magazine 4, the endless, strip-shaped underlay element is prepared in a rolled-up form for processing. In the context of the invention it is also possible to provide the strip-shaped underlay element in the storage magazine 4 instead of in a rolled-up form in a folded arrangement. However, it is also possible to arrange a plurality of strip-shaped underlay elements stacked on top of one another or layered next to one another in a corresponding storage magazine 4. The same applies to strip-shaped strips which are formed from individual, successive sub-elements or are fitted with sub-elements. The freely opening area 13 of the guide element 6 is appropriately aligned in the displacement or travel direction 14 of the device. Depending on the area of application or depending on the type of support elements used, the freely opening area can also be oriented at an acute angle or at right angles to the displacement or travel direction 14 of the device.

The guide element 6 is expediently guided from the area adjacent to the screw or setting axis on the underside of the device into the area of the storage magazine 4. At the end region facing the storage magazine 4, the guide element 6 is equipped with a bent-away insertion skid 15. The Führungseieme-nt ^'6 is zumin¬ least over part of its length as a closed, approximately to the cross section of the strip-shaped Unterlegelementes out 5 adapted aus¬ channel, but can be also open on one side over a portion of its length, in which case only on both sides webs encompassing the edge region of the strip-shaped underlay element 5 are provided.

As already stated, the storage magazine 4 in the exemplary embodiment shown is designed as a rotatably mounted roller 16 on which the endless, strip-shaped base element 5 is wound. In this way, a very simple construction is possible, and besides ^, a rapid replacement of the prepared underlay elements is possible. The storage magazine 4 is held in a structurally simple manner via two mounting rails 17 and 18, one end of which can be attached to the top of the housing 1. However, another fastening variant is also conceivable. For reasons of space and also for easy observation of the storage magazine 4, it is advantageous if the storage magazine 4 is arranged in front of the screwing or setting axis, as seen in the displacement or travel direction 14 of the device.

It can be seen from FIGS. 4 and 5 how the fastening of sheet-like components made of an insulating material to a solid substructure takes place. Thus, sheet-like or plate-like components 20 made of an insulating material are placed on a solid substructure 19, which is formed here from a profiled sheet, these components 20 then being made by a sealing film 21 are covered. In FIG. 4 is the fastening an edge portion of such a film 21 ar shown and IR Fig. The foils 21 be c "i ^c Befe¬ stigung somewhere in the region of the closed film 21 of the shock overlaps Ar, wherein initially the fastening of the lower edge area of the film 21. The strip-shaped underlay element 5 lies here on the film 21 and screws 9 are screwed in at certain, prescribed intervals. The edge area of the film 21 lying above then becomes the edge area of the other film 21 and the strip-shaped underlay element and the screws 9 are glued so as to overlap in the same way in the example according to Fig. 5, with a strip-shaped film section 22 being glued over the fastening seam, thereby ensuring a secure seal, particularly in the case of a roofing membrane achieve.

The strip-shaped shim 5 is expediently made ^'a biegsa- men, however, formed in the screwing process and in the subsequent bracket suitably resistant plastic tape. If fastenings are prescribed at certain intervals, then the strip-shaped underlay element 5 can be provided with prefabricated holes 23 which follow one another at a certain grid spacing. It is also possible to carry out this strip-shaped underlay element with a transverse and / or longitudinal profiling, depending on the intended use, the profiling being able to be more pronounced when stacking or folding pre-stacking than when rolling pre-stacking.

Instead of a function of a Unterlegelementes engaging, strip-fenförmigen ^{Unterlegelementes'} 5 can with the inventive Vorrich¬ tung a belt 24 to be processed, which carries successive equally spaced following grossflachige washers 25th The band 24 can then be cut off in the area between two large-area washers 25. However, it is also possible to leave the respective band section below a washer 25 and to use this as an additional sealing film for the screw connection, or else to remove the corresponding band section before the screw connection by appropriate measures. As can be seen from FIGS. 7 and 8, such a strip-like band 24 can be used to store and store large washers of the most varied dimensions and designs, it being irrelevant whether these washers are made of plastic or metal .

As can be seen from FIG. 9, the strip-shaped washer element 5 can also be produced from individual, large-area washers 25 made of plastic or metal, which are connected to one another via strip-like or cord-like support parts 26. It is possible to form these strip-shaped underlay elements in one piece, in which case the respective intermediate support members 26 are separated as required.

In the case of an arrangement of the individual washers 25 in relatively close succession, the strips 24 or supporting parts 26 are each cut off or torn off along a dividing line 27.

In this context, it is advantageous to assign a cutting device to the end region of the guide element 6 for severing the strip-shaped underlay element 5 or the band carrying the washers 25. Such a cutting device can be constructed in a wide variety of ways and is therefore based on known design measures.

If a continuous, endless, strip-shaped underlay element 5 is used, then the question of the advance is not a problem, since the strip-shaped underlay element is already continuously processed by the storage magazine 4 by the movement of the device. If, however, the feed is to take place in each case around individual washers 25 applied to a belt 24 or when a feed of an embodiment of the washer element 5 according to FIG. 9 is carried out, then it is expedient if in the region of the guide element 6 a mechanical feed device for the strip-shaped washer element or band is provided.

To improve the automation even when processing strip-shaped support elements 5 or corresponding strips 4, it is appropriate when the feed device and / or the cutting device can be actuated as a function of the travel movement of the device and / or the lifting movement of the screwing or setting device. Then the device, in which the supply of screws and washers has already been effected as a function of the displacement movement of the screwing device, can also be used for the automatic feed of a strip-shaped base element or a corresponding bale of the used.

The device according to the invention has made it possible to use both endless, strip-shaped underlay elements or to magazine individual washers in a simple manner. However, it has also been possible to provide so-called long support elements, each of which extends over two or more screwing points.

The invention can be used not only in the fastening of insulating sheets or panels to a solid substructure, but wherever web-like, plate-like and / or profile-like components are somehow attached to a solid substructure by means of fastening means with the use of underlay elements should be. When fastening profile-like components to a fixed substructure, for example, a strip-shaped underlay element can simultaneously act as a sealing element below the screw head, in order to seal the screw connection.
