DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0057] FIG. 1 shows a device 1 according to the invention in a perspectival representation. The device 1 comprises a base frame 2, which in the present case has frame structures with rectangular tubes connected to one another essentially at right angles. The design shown here is exemplary and represents only one possible embodiment of the base frame 2. A storing unit 3 which serves to accommodate edge bands 4 is arranged between two sides 2a, 2b of the base frame 2, which have frame structures spaced apart from one another. In the present case, the construction of the storing unit 3 is the same as that of the base frame 2, since it also has a frame structure with rectangular tubes connected to one another essentially at right angles.

[0058] Due to the correspondingly smaller design of the storing unit 3 compared to the base frame 2, the storing unit 3 in the embodiment shown here by way of example is located within the internal dimensions of the base frame 2, wherein the storing unit 3 is guided so as to be linearly movable with its opposite sides 3a, 3b on the sides 2a, 2b of the base frame 2. In contrast, the length of the storing unit 3 extending parallel to its sides 3a, 3b is shorter than the base frame 2, so that it is movable within the base frame 2 with a corresponding stroke length a relative to the base frame. For this purpose, rails 5 are arranged in a suitable manner on the base frame 2. As can be seen by way of example in FIG. 1, one of these rails 5 can be arranged on one of the opposing inner surfaces of the frame structures extending between the two sides 2a, 2b of the base frame 2, so that each of the sides 2a, 2b has two such rails 5. Regions of the storing unit 3 that correspond to these rails 5 (and are not shown in greater detail here) ultimately facilitate its linear mobility with respect to the base frame 2. The linear movement of the storing unit 3 is preferably carried out by a drive which cannot be seen here; however, it can of course take place manually as an alternative or in addition to this.

[0059] Looking at the storing unit 3, it becomes clear that it has a large number of support elements 6a, 6b arranged on its two sides 3a, 3b. In the present case, the support elements 6a, 6b are designed like rails, which each extend perpendicular to the length of the storing unit 3 on the two sides 2a, 2b of the base frame 2. The support elements 6a, 6b can be seen here on the inner surfaces of the rectangular tubes, located on each side 3a, 3b of the storing unit 3, of the frame structures. The support elements 6a, 6b can be mounted on the sides 3a, 3b of the storing unit 3 so as to be linearly movable in relation to their lateral spacing from one another, in a manner that is not shown in detail.

[0060] The support elements 6a, 6b subdivide the interior of the storing unit 3 into individual storage places 7, wherein two support elements 6a, 6b lying opposite one another in relation to the two sides 3a, 3b of the storing unit 3 define a storage place 7. The storage places 7 defined in this way serve to accommodate the edge bands 4, which in the present case are each arranged at least partially rolled up to form an edge roller within a cartridge 4a. The cartridges 4a have side surfaces which correspond to the support elements 6a, 6b and enable them to be pushed into and pulled out of the storing unit 3 accordingly. Alternatively, and not shown in more detail, the individual storage places 7 can also be defined by floor elements which then extend at least partially between the sides 3a, 3b of the storing unit 3.

[0061] The floor elements can be connected to the storing unit 3 in a fixed or movable manner, so that they enable it to be pulled out of the storing unit 3 in the manner of a drawer. In contrast to the loading of the storing unit 3 with cartridges 4a containing edge bands 4, the floor elements enable edge bands 4 to be accommodated directlyfor example, by placing them on the floor elements. Of course, the floor elements can also be combined with the support elements 6a, 6b which accommodate the cartridges 4a. It is also conceivable that the support elements 6a, 6b serve to support floor elements, so that, in this way, edge bands 4 can also be arranged directly in the storing unit 3. Furthermore, what has been said above with regard to the support elements 6a, 6b can also apply to these floor elements, with regard to their possible change in spacing from one another by a movable connection to the storing unit 3.

[0062] The device 1 or the storing unit 3 can have a drive unit, not shown in detail, via which at least portions of an edge band 4 can be actively driven if required. The drive unit can interact either directly with the relevant edge band 4 or with a cartridge 4a containing the edge band 4. Furthermore, the device 1 or the storing unit 3 can have a brake unit, likewise not shown in detail, by means of which an edge band 4 can be braked and/or fixed with respect to its mobility. The brake unit can interact either directly with the relevant edge band 4 or with a cartridge 4a containing the edge band 4. The device 1 or the storing unit 3 can also have a cutting arrangement, also not shown in detail, by means of which a portion of an edge band 4 can be cut off. The cutting arrangement can interact either directly with the relevant edge band 4 or with a cartridge 4a containing the edge band 4. Depending upon the design, the drive unit or brake unit or cutting arrangement can also be at least part of a cartridge 4, which can be controlled via a corresponding control of the device 1 or of the storing unit 3. A division into two would also be conceivable in that the cartridges 4a comprise the corresponding mechanical parts of the drive unit or brake unit or cutting arrangement, while the device 1 or the storing unit 3 have the corresponding drive for this, which can then be coupled to them.

[0063] In principle, the device 1 can be aligned in such a way that its storing unit 3as can be seen in FIG. 1is linearly movable parallel to a vertical Z relative to the base frame 2. In contrast, the device 1 can of course also be used in an orientation rotated by 90?, so that its storing unit 3 is linearly movable parallel to a horizontal X relative to the base frame 2.

[0064] FIG. 2 shows the top view of an edge banding system 8, which comprises an edge banding machine 9 and the device 1 explained in more detail above. It can be seen that the device 1 is located directly in front of the edge banding machine 9 in relation to a spacing direction Y running at right angles to the horizontal X and to the vertical Z. As a result, the device 1 is arranged in the region of the edge banding machine 8 in such a way that one of the edge bands 4 arranged in the device 1 is guided directly from the storing unit 3 of the device 1 into the edge banding machine 9. The position of the device 1 is chosen so that the edge band 4 runs directly into an edge feed 9a of the edge banding machine 9, through which it is used, in a manner not shown, for edge banding panels, and in particular wood-based panels. Previously, the storage place 7 of the device 1 loaded with the desired edge band 4 was arranged in the plane of the edge feed 9a, in that its storing unit 3 was moved linearly by a movement running parallel to the vertical Z in the present case.

[0065] Due to the almost direct entry of an edge band 4 into the edge feed 9a of the edge banding machine 9, the otherwise exposed portion of an edge band 4 between the device 1 and the edge banding machine 9 is reduced to a minimum, which leads to significantly reduced stresses within the course of the edge band 4. In addition, the direct feeding of the edge band 4 into the edge banding machine 9 eliminates any threading effort and the adjustment work required here.

[0066] Depending upon the requirements, the edge banding system 8 can be designed in such a way that the device 1 can be moved relative to the edge banding machine 9, which, with regard to the representation of FIG. 2, means the displacement in and counter to directions parallel to the horizontal X and/or to the spacing direction Y. For example, the device can be movable relative to the device 1 in a direction running parallel counter to the spacing direction Y, in order to be able to carry out any maintenance work. Here, for example, free access to the edge feed 9a is made possible. Of course, this displaceability can also be used to move the device 1, for example, if necessary, between two edge banding machines 9 spaced parallel to one another, in order to be able to provide the edge band 4 required in each case on one or the other edge banding machine 9.

[0067] FIGS. 3 through 7 each show extended expansion stages of the device 1, by means of which the performance of the device can be increased with regard to the provision of edge bands 4.

[0068] FIG. 3 shows a first extended expansion stage in which the device 1 is combined with a manipulator 10. In the present case, an embodiment of the manipulator 10 as a storage and retrieval machine (SRM) is shown, which is linearly movable parallel to the lifting direction of the device 1. Specifically, for this purpose, the manipulator 10 has a lifting unit 10b mounted so as to be linearly movable in a frame 10a, which can accommodate at least one edge band 4 or a cartridge 4a loaded with an edge band 4. The manipulator 10 serves to load the device 1 with edge bands 4 or with cartridges 4a each containing an edge band 4, and to empty the device 1. In this expansion stage, the manipulator 10 can be loaded manually. The manipulator 10 can be moved synchronously with the device 1 by means of a corresponding coupling. This coupling can take place mechanically and/or by means of control technology. A corresponding control of the manipulator 10 enables the device 1 to be loaded and unloaded even during operation.

[0069] FIG. 4 shows a further expansion stage of the device 1 which, compared to the expansion stage from FIG. 3, is now additionally combined with a storage arrangement 11. In the present case, the storage arrangement 11 is designed like a shelf system withas already explained above with regard to the device 1lateral support elements 11a in the form of rails that have a plurality of slots 11b arranged one above the other for edge bands 4 or for cartridges 4a each containing one edge band 4. With the help of the manipulator 10, edge bands 4 that can be stored in the storage arrangement 11 can now be removed therefrom individually or at least in pairs and can be transferred to the device 1, wherein the storage places 7 of their storing unit 3 are correspondingly loaded. For this purpose, the linearly movable lifting unit 10b of the manipulator 10 is moved into the required plane of the storage arrangement 11, where it removes an edge band 4 or the cartridge 4a containing the edge band 4 from the related slot 11b. Then, if necessary, the lifting unit 10b of the manipulator 10 moves into another plane in order to transfer the edge band 4 or the cartridge 4a to a free storage place 7 of the storing unit 3 of the device 1. Of course, this can also be done the other way around, in order to feed edge bands 4 or cartridges 4a out of the device 1 to the storage arrangement 11.

[0070] FIG. 5 illustrates the structure of a further expansion stage which additionally includes a transfer device 12. It can be seen that in the present case the transfer device 12 is arranged on the device 1, where it corresponds to a machine store 13. The machine store 13 is located above or directly on the edge banding machine 9 in a manner not shown in greater detail. In this arrangement, the storage arrangement 11 serves as a buffer for edge bands 4 or cartridges 4a, while the transfer device 12 feeds and removes new edge bands 4 or cartridges 4apreferably, fully automatically. In other words, edge bands 4 or cartridges 4a, which can be stored in the machine store 13 provided here by way of example near the machine, can be transferred to the manipulator 10 individually or at least in pairs. In contrast, edge bands 4 or cartridges 4a arranged in the storing unit 3 and/or the storage arrangement 11 can be transferred individually or at least in pairs to the transfer device 12 by the manipulator 10.

[0071] FIG. 6 shows an expansion stage which comprises a duplication of the structure already shown in FIG. 4. Specifically, two devices 1 are provided here, each of which is combined with its own manipulator 10 and a storage arrangement 11 located on the relevant manipulator 10. As a result of this structure, the two devices 1 can work alternately, so that correspondingly high cycle rates can be achieved. For this embodiment, the edge banding machine 9 has two edge feeds 9a, not shown here, in order to be able to process the edge bands 4 of the relevant device 1.

[0072] FIG. 7 shows a last possible expansion stage, which comprises a duplication of the structure already shown in FIG. 5. Specifically, two devices 1 are also provided, each of which is combined with its own manipulator 10 and a storage arrangement 11 located on the relevant manipulator 10, as well as a transfer device 12 and a machine store 13in particular, near the machine. Here, too, the two devices 1 can work alternately in order to achieve a high cycle rate for the edge banding of panels.

[0073] In principle, the device 1 of all expansion stages can be equipped with at least one reading module (not shown in detail). Specifically, the reading module can be arranged in the region of the storing unit 3. It is also conceivable that each storage place 7 of the storing unit 3 be equipped with such a reading module. A reading module can be arranged also at other locationsfor example, on the base frame 2 or the storage arrangement 11 or on one or a plurality of its storage places. The aim is the automated transmission of information about the respective edge bands 4 or cartridges 4a, which are currently in the storing unit 3 or which are removed from it or are just being fed in. Thus, the edge bands 4 or cartridges 4a can be equipped with a corresponding transmission module on which the required information is stored. Such a transmission module can preferably contain at least one RFID chip or can be designed as such a chip. The reading module or the reading modules are set up to communicate with the transmission modules. This can take place in one direction or in both directions, which means the mere reading out of data or a combination of reading out and writing of data by the reading module on a transmission module.

[0074] In an advantageous manner, the device 1 according to the invention can comprise at least one interface (not shown in greater detail here). This interface is then designed to be coupled to at least one further component or machinein particular, mechanically and/or in a data-transferring manner. In this way, all components or machines of an edge banding system 8 can be controlled via a corresponding controller.

[0075] The device 1 shown in FIG. 1, and also shown only by way of example in the other FIGS. 3 through 7, is shown in FIGS. 8 and 9 in alternative embodimentsin each case in a perspectival representation. To avoid repetition and for better clarity, only some of the reference signs can be recognized here, since identical parts correspond to the parts already shown in FIGS. 1 through 7. The essential difference between the variants shown in FIGS. 8 and 9 lies in the different shape of the base frame 2 carrying the storing unit 3.

[0076] It can be seen from FIG. 8 that, in this variant of an embodiment, the frame structures each located on one of the two sides 2a, 2b of the base frame 2 are connected to one another via two rectangular tubes extending between them and parallel to the horizontal X. In contrast, the base frame 2 shown in FIGS. 1 and 3 through 7 has a total of four rectangular tubes connecting its two frame structures, each located on one side 2a, 2b, which tubes extend there between the opposite corners of said frame structures and parallel to the horizontal X. In the variant shown in FIG. 8, the rectangular tubes connecting the frame structures lie one above the other in relation to the vertical Z, so that the base frame 2 is essentially U-shaped in a top view, which is not shown in detail here.

[0077] FIG. 9 shows a variant of an embodiment, in which the view of the base frame 2 may be designated as L-shaped. It can be seen that the base frame 2 has a frame structure located on only one side 2a, while the opposite side 2b is more or less frameless. As already shown in FIGS. 1 through 7, the lower region of the base frame 2, which is composed of rectangular tubes, is designed to be closed. Specifically, the two rectangular tubes running parallel to the horizontal X each extend away from a lower corner of the frame structure located on the side 2a, and they are connected to one another at the end via a rectangular tube running parallel to the spacing direction Y. With the inclusion of the frame structure located on the side 2a, a closed, essentially rectangular shape is produced.

[0078] Further variants, not shown in detail here, for the base frame 2 are also conceivablefor example, in the form of a central lifting column below the storing unit 3.

[0079] Of course, the profiles referred to as rectangular tubes in the context of the description can alsounlike in FIGS. 1 through 9have a different cross-sectional shape, such as a U-, C-, or L-shape. A design as a round tube is also conceivable here. Combinations of the above are also possible, as well as variants thereof within a base frame 2.

[0080] The function of the cutting arrangement 14, 14, 14 according to the invention is explained in more detail with reference to FIGS. 10 and 11. FIGS. 10 and 11 show a detail of an edge banding system according to the invention in the region of an edge banding machine 9, adjacent to which the device 1 according to the invention is arranged. In the device 1 according to the invention, an edge roller or edge cartridge 4a is in the working position in the example shown. Working position means that the edge roller or edge cartridge 4a is located in the storing unit 3 in the vertical direction Z at level with the edge feed 9a, so that the edge band 4 is pulled in from the edge roller or from the edge cartridge 4a via the edge feed 9a into an edge feed line 15 by means of a suitable pull-in mechanism (not shown) and is transported in the direction of a pressure unit 16, which generally has at least one pressure roller 16a, in order to be pressed there against the narrow side of a workpiece 17. As shown in FIG. 10, the edge roller or edge cartridge 4a is in the working position. In the example of FIG. 10, a cutting arrangement 14 is arranged on the edge banding machine 9 in the region of the working position. The cutting arrangement is preferably located in the immediate vicinity of the edge roller or edge cartridge 4a. Immediate vicinity means that the cutting arrangement 14 should be arranged at least in the region of the end, remote from the pressure device 16, of the feed line 15. As in the example of FIG. 10, this can be achieved in that the cutting arrangement 14 is arranged on or in the region of the end, facing the device 1, of the feed line 15.

[0081] Alternatively or additionally, a cutting arrangement 14 or 14 can also be arranged on the device 1 itself, so that the cutting arrangement 14 or 14 is then arranged in the region of the edge feed 9a on the portion, facing the feed line 15, of the device 1 or base frame 2 or storing unit 3. It can advantageously be provided for the cutting arrangement 14 or 14 to be arranged in the region of the device 1 such that, if the edge roller is designed as an edge cartridge 4a, it is able to cut off the edge band 4 at a point which is still located inside the edge cartridge 4a (this cutting position is denoted by P2 in FIG. 11), or is outside the edge cartridge 4a. By way of example, this cutting position is denoted by P2 in FIG. 11. The alternative or additional arrangement of the cutting arrangement 14 on the edge banding machine 9 or a stand (not shown) between the edge banding machine 9 and the device 1 cuts off the edge band 4 at a cutting position P1. In principle, it applies to each of the cutting arrangements 14, 14, 14 that they can be designed as a knife which can be displaced into the transport path of the edge band 14 in order to cut through the edge band at position P1 or P2, in order to separate a cut-off edge band to be attached to a workpiece 17 from the rest of the edge roller.

[0082] The advantage of arranging the cutting arrangement in the region of the working position of the edge roller or edge cartridge 4a is that, before switching to another edge roller or edge cartridge 4a, the edge band does not have to be retracted again over the entire feed line 15, i.e., it does not have to be wound onto the roller or retracted into the edge cartridge 4a, but is cut off already, such that the step of retracting or reeling can be saved upon. This saves time, and one can switch to a different edge band. This is particularly advantageous if the cutting arrangement can cut off the edge band 4 already within an edge cartridge 4a, as indicated, for example, by the positions of the cutting arrangements 14 or 14, since the associated edge cartridge 4a is then immediately moved from the working position into a storage position after cutting, and a different edge cartridge can be brought into the working position by moving the storing unit 3.
