Definitions
- the invention relates to a device for providing edge bands according to the preamble of claim 1 and an edging system with such a device with the features of claim 15.
- the invention also relates to a method for changing an edging roll or edging cassette with the features of claim 21 and a use of the device or the edging system according to the features of claim 23.
- Boards made of wood or wood substitutes for the furniture industry usually have at least one at least partially coated top surface before they are processed.
- the types of these coatings range from lacquer finishes to paneling with layers of real wood veneer or plastic.
- the surfaces coated in this way have increased resistance to mechanical influences and liquids.
- the narrow edges of these panels are usually only coated afterwards, for example after they have been cut to size.
- edging a suitable edge band is attached to the narrow sides of the panel, at least in sections. Their bond with the panel is usually based on adhesion or a micro form fit through local melting
- the edging of wood-based panels is carried out by an edging system in which the edge bands are attached with at least one edging machine.
- edgebands are usually in rolled-up form as edge rolls in order to be able to safely transport and store even large lengths in the most compact manner possible. For the simplest possible handling, these can also be arranged within a cassette and can be unwound from this if necessary. Due to the variety of colors and decors as well as thicknesses (thickness) of the boards to be edged, the then also different edge bands often have to be exchanged for the appropriate variant.
- EP 1 346 805 A2 discloses a device for preparing edging strips, which includes a tower-like storage unit.
- the storage unit has individual storage locations that are designed for at least indirect fitting with edge bands.
- the storage locations are located one above the other in relation to a vertical.
- a storage place of the storage unit serves as a fixed changing place position, which corresponds to a storage table which is arranged on the outside of the storage unit and is at the same height.
- a cassette fitted with an edge roller can be inserted into the changing position in a dog-like manner.
- This cassette is then sorted into another storage location within the storage unit by a handling device arranged on the opposite side of the storage unit.
- a cassette to be exchanged is first pulled out of its storage location within the storage unit by means of the handling device and transferred to the exchange location position, from where it can be removed again like a dog and, for example, to the inserting a new edging roll is placed on the storage table.
- An edging machine is supplied with edging tapes via the handling device of the device, which removes the cassette required for this purpose from the storage unit and transfers it to the edging machine.
- the present invention is therefore based on the object of further developing a generic device and an edging system equipped therewith such that the provision of edging strips can take place more economically overall.
- this object is achieved in a device for providing edgebands with the features of claim 1. Furthermore, this object is achieved by an edging system with the features of claim 15 and a method according to claim 21 solved.

- the device according to the invention can stand on a base via its base frame and/or be attached to another component, while the storage unit designed to accommodate edge bands is arranged so that it can be displaced linearly relative to the base frame. According to the invention, this is done in such a way that a selected edging roll can be shifted into a working position in which the edging tape located on the edging roll can be taken over by an edging feed of an edging machine.
- At least one cutting arrangement is arranged, preferably on the device or the edging machine or on a stand arranged in particular between the device and the edging machine, by means of which a section of an edge band, in particular unwound from an edge roll, can be separated at a cutting position in the region of the working position is.
- the configuration according to the invention does not require any rearrangement of edge bands or cassettes within the storage unit, since the edge band required in each case can be shifted into the required level relative to an edging machine, regardless of its arrangement in one of the storage locations, simply because of the linear mobility of the storage unit. In this way, the handling device required for the previously necessary distribution of edge bands within the storage unit can be omitted. Moreover, there is no longer a compelling need for one Transfer of an entire roll of edging tape to an edging machine, since this can now be fed directly from the storage unit, in that the storage space containing the required edging tape can be positioned beforehand, for example opposite an edging feed of the edging machine.
- At least one storage location of the storage unit can be designed in such a way that it can accommodate at least one edge band.
- this storage location can be designed in such a way that a loose edge band, in particular in its form at least partially wound up to form an edge roll, can be arranged or stored in it.
- at least one of the storage locations can be designed to accommodate a cassette that at least partially contains the edging strip.
- the storage unit has two opposite sides, and the design of its storage locations can advantageously be adapted to the shape of the edge bands to be accommodated.

- an adaptation to edge bands having different widths or heights of their cassettes can be undertaken in this way.
- the respective storage location can be adjusted with as little play as possible in relation to the edge band to be picked up. It is also conceivable to adjust the number of storage locations in this way, which can be increased by one or even more locations, for example by adapting them to correspondingly narrow edge bands.
- the device in particular the base frame and/or the storage unit and/or each storage location of the storage unit and/or a manipulator that can move an edge roller and/or an edge cassette and/or a storage arrangement, which can accommodate one or a plurality of edge rollers, and/or at a storage location of the storage arrangement, be equipped with at least one reading module.
- this can be a so-called contactless reading module, which can then correspondingly wirelessly receive transmitted data.
- the reading module is set up to correspond with at least one transmission module of an edge band or a cassette containing the edge band.
- an RFID chip can be arranged in or on an edge band or its cassette, which has a corresponding external excitation in it transfers stored data to the reading module.
- required information about the edgeband to be arranged in one of the storage locations can be transmitted to the device, which can then be used to control the storage unit in particular.

- the device and/or a controller activating it to know more or less about the edge bands kept in the storage unit and their respective storage location, in order to provide the requested or required edge band in each case be able.
- the reading module itself or an additional component contains a transmission unit, which in turn can transmit information to the transmission module of the respective edge band, which can then be written to, for example.
- information about the remaining length of the edge band can be stored in its transmission module, so that edge bands that have a remaining length required for the forthcoming edging can always be used.
- the device has a drive, by means of which the storage unit can be correspondingly and automatically displaced with respect to the base frame.
- the storage unit it is also possible for the storage unit to be moved manually relative to the base frame of the device.
- a device that is rather simple in its expansion stage can thus require the manual relocation of its storage unit, while its higher expansion stage provides for a correspondingly controlled drive.
- a device equipped with such a drive can device to enable their storage unit to be moved manually, in order to facilitate maintenance work and/or to be able to guarantee the usability of the device through manual handling even in the event of a defect in the drive, for example.
- the device according to the invention can have an interface which can be coupled to at least one other component or machine.
- the interface can enable a mechanical and/or data-transmitting coupling. This allows, for example, simple integration into existing system structures and their operational processes, since signals available from the existing system or its controller can be transmitted to the device via the interface and/or signals can be transmitted from the device to the existing system or whose control can be passed on.
- the device can have at least one drive unit, via which an edge band can be actively driven at least in sections.
- an edge band can be actively driven at least in sections.
- the drive unit can at least transfer the edgeband from its storage location to an edging machine.
- the tracking of the edgeband into the edging machine can also take place entirely via the drive unit or at least be supported by it.
- an active rotation of the wound edge band and/or at least one friction wheel would be conceivable for this purpose, which has peripheral contact with the edge band or a component that interacts with the edge band and this drives at least in sections by a rotation or from reels.
- the drive unit can interact with an edge band that is at least partially arranged within a cassette or with an edge band that is present without such a cassette.
- the device can preferably have at least one brake unit, via which an edge band can be braked and/or fixed with respect to its mobility.
- Both its controlled drive and its uncontrolled movement behavior are considered to be mobility of the edgeband, which can be attributed in particular to stresses within its material, which can/can result from the rolled-up state and/or temperature fluctuations. Of course, this also includes all other influences causing movement of the edgeband, such as vibrations.
- the brake unit is designed in such a way that it at least brakes the movement of the same, which occurs, for example, by pulling on a section of the edge band.
- the braking unit can preferably fix the edgeband in such a way that its free end can always be checked.

- the cutting arrangement according to the invention can be arranged in different ways. According to an advantageous embodiment it is provided that the or at least one cutting arrangement on the base frame and/or on the storage unit and/or on an edge feed and/or on the Edging machine and / or is arranged on a separate stand, which can be arranged between the device and the edging machine. For example, only one edgeband section can be transferred to an edging machine, the length of which, cut off by the cutting arrangement, corresponds to the length to be processed.
- the cutting arrangement can interact with an edge band that is arranged at least partially within a cassette or with an edge band that is present without such a cassette.
- the device can extend either vertically or horizontally in its intended arrangement.
- its storage unit can be correspondingly linearly displaceable parallel to a vertical line or parallel to a horizontal line in relation to the base frame.
- this results in advantageous options for using the available installation space.
- the storage unit it is possible for the storage unit to be displaceable at an angle of between 45° and 90°, preferably between 75° and 90°, to the horizontal relative to the base frame.
- Such an arrangement can be realized in particular in such a way that the orientation then not only has a directional component in the vertical direction, but also has a second directional component in or counter to the direction of feed of the workpieces to be coated with the edging strip.
- the height of the edging supply on an edging machine limits the maximum possible height of the storage unit for direct unwinding of an edging strip from its storage location, since its uppermost storage space must be in the level of the edging supply for this purpose.
- the maximum number of possible storage locations results from the space available below this level. Any indentations in the subsoil naturally permit greater heights for the storage unit, since in its maximally lowered position it would then be displaceable, at least in sections, into such an indentation.
- edge bands held in this device can generally run into an edging machine without rotating about their longitudinal axis.
- the decisive factor here is their orientation in relation to their cross section, which runs parallel to the wood-based panels that are usually processed lying flat.
- a horizontal orientation of the device requires a 90° rotation of an edge band about its longitudinal axis in order to align this edge band lying within the storage unit with respect to its cross section parallel to the narrow edge sides of a wood-based panel.
- the twisting of an edge band in its longitudinal direction can stress its structure and negatively affect the process reliability of the edge band feed.
- the horizontal orientation of the pro- direction a greater length of its storage unit, so that it provides correspondingly more storage space for edge bands.
- the more advantageous orientation of the device is to be selected on the basis of the criteria mentioned by the person skilled in the art in each individual case.

- the manipulator is arranged and set up in such a way that it can reach every storage location in the storage unit.
- the manipulator can be used to load and empty the storage locations with edge bands by removing the edge bands from the storage locations or pushing them into the storage locations as required.
- this is independent of whether the respective edge bands are present as such or are at least partially arranged within a cassette.
- the manipulator enables further automation of the device.
- the device according to the invention can also have a storage arrangement.
- the storage arrangement is used for the local provision of edge bands or cassettes containing edge bands. With the help of the manipulator, these can then be removed individually or at least in pairs from the storage arrangement and transferred to the storage device of the device. In this way, the storage locations of the storage unit can be equipped individually with edge bands from the storage arrangement.
- the storage arrangement is used for the local provision of edging tapes or cassettes containing edging tapes, which are processed by the mani- pulator can be removed individually or at least in pairs from the storage device, in order to then be transferred to the memory arrangement.
- the combination of storage arrangement and manipulator allows the number of edge bands that can be kept locally to be increased accordingly, which enables shorter reaction times and/or a greater selection of edge bands that differ from one another.
- a transfer device can also be provided, through which additional edge bands stored in a nearby machine store can be accessed. Edge bands located in the machine storage can be removed individually or at least in pairs by the transfer device and transferred to the manipulator, which can then be transferred to the storage arrangement and/or the storage unit. Conversely, edge bands located in the storage arrangement and/or the storage unit can be removed individually or at least in pairs by the manipulator and passed on to the transfer device, from where they can be transferred back to the machine store.
- the device according to the invention makes it possible overall to provide edgebands in an extremely economical manner.
- the linear relocatability of the storage unit that can be fitted with edge bands makes a decisive contribution to storing an edge band in one of the free storage locations in a quasi-disordered manner. If necessary, this can be achieved by simply moving the entire storage unit to the required level, ie the working position, opposite an edging machine. be brought in order to be able to access the edging tape inside. A previous, in particular mechanical, sorting of the edge bands is no longer necessary.
- edge bands held available in the storage unit This is based on the knowledge of data about the edge bands held available in the storage unit, which results from the communication that is possible at least in one direction between the device and the respective edge band or the cassette containing the edge band.
- the currently required edging tape can always be positioned at the edging feed level of the edging machine via a corresponding control in order to enter the edging machine.

- the device 1 can be aligned in such a way that its storage unit 3 - as in Fig. 1 can be seen - parallel to a vertical Z relative to the base frame 2 is linearly displaceable.
- the device 1 can of course also be used in an orientation rotated by 90°, so that its storage unit 3 can be linearly displaced parallel to a horizontal line X with respect to the base frame 2 .
- Fig. 2 shows the top view of an edging system 8, which includes an edging machine 9 and the device 1 explained in more detail above.
- the device 1 is located directly in front of the edging machine 9 in relation to a distance direction Y running at right angles to the horizontal X and the vertical Z.
- the device 1 is arranged in the area of the edging machine 8 in such a way that one of the edge bands 4 arranged in the device 1 is led directly out of the storage unit 3 of the device 1 into the edging machine 9 .
- the position of the device 1 is chosen so that the edgeband 4 runs directly into an edge feed 9a of the edging machine 9, by which it is used in a manner not shown for edging panels, in particular wood-based panels.
- the storage location 7 of the device 1 stocked with the desired edging strip 4 was arranged in the plane of the edging supply 9a, in that its storage unit 3 was linearly displaced by a movement running parallel to the vertical Z in the present case.
- the edging system 8 can be designed in such a way that the device 1 can be displaced relative to the edging machine 9, which in relation to the illustration in FIG Distance direction Y means.
- the device can be displaceable relative to the device 1 in a parallel direction running opposite to the distance direction Y, in order to be able to carry out any maintenance work.
- free access to the edge feed 9a is made possible.
- this displaceability can also be used to move the device 1, for example, between two edging machines 9 spaced parallel to one another, as required, in order to be able to provide the required edging tape 4 on one or the other edging machine 9.
- Fig. 3 to Fig. 7 each show expanded stages of development
- FIG. 3 shows a first, expanded stage of development, in which the device 1 is combined with a manipulator 10 .
- An exemplary embodiment of the manipulator 10 is shown here as a storage and retrieval device (RBG) which has a linear displaceability running parallel to the lifting direction of the device 1 .
- the manipulator 10 specifically has a lifting unit 10b which is mounted in a linearly movable manner in a frame 10a and which can accommodate at least one edging strip 4 or a cassette 4a equipped with an edging strip 4 .
- the manipulator 10 is used to equip the Device 1 with edge bands 4 or with cassettes 4a each containing an edge band 4 and the emptying of 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.
- 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 memory arrangement 11 .
- the storage arrangement 11 is in the present case like a shelving system with lateral support elements 11a in the form of rails, as already explained above for device 1, which have a large number of superimposed slots 11b for edge bands 4 or cassettes 4a each containing an edge band 4.
- edge bands 4 that can be kept available in the storage arrangement 11 can now be removed individually or at least in pairs from this and transferred to the device 1, with the storage locations 7 of the storage unit 3 being stocked accordingly.
- the linearly displaceable lifting unit 10b of the manipulator 10 is moved into the required level of the storage arrangement 11, where it removes an edge band 4 or the cassette 4a containing the edge band 4 from the respective slot 11b. Then, if necessary, the lifting unit 10b of the manipulator 10 moves to another level in order to transfer the edging strip 4 or the cassette 4a to a free storage location 7 of the storage unit 3 of the device 1 . Of course, this can also be done in the opposite way, in order to feed edge bands 4 or cassettes 4a out of the device 1 to the storage arrangement 11.
- Fig. 5 illustrates the structure of a further expansion stage, which also includes a transfer device 12.
- the transfer device 12 is arranged on the device 1 in the present case, where it corresponds to a machine bearing 13 .
- the machine storage 13 is located above or directly on the edging machine 9 in a way that is not shown in detail.
- the storage arrangement 11 serves as a buffer for edging strips 4 or cassettes 4a, while the transfer device 12 preferably supplies new edging strips 4 or Feeds and takes out cassettes 4a.
- edge bands 4 or cassettes 4a that can be kept available in the machine storage 13 provided here, for example, close to the machine, can be transferred individually or at least in pairs to the manipulator 10.
- edge bands 4 or cassettes 4a arranged in the storage unit 3 and/or the storage arrangement 11 can be transferred individually or at least in pairs by the manipulator 10 to the transfer device 12 .
- FIG. 6 shows an expansion stage that includes a doubling of the structure already shown in FIG. 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 respective manipulator 10 .
- This structure allows the two devices 1 to work alternately, which means that correspondingly high cycle rates can be achieved.
- the edging machine 9 has two edge feeds 9a (not shown in detail here) in order to be able to process the edge bands 4 of the respective device 1.
- FIG. 7 shows a final possible expansion stage, which includes a doubling of the structure already shown in FIG.
- two devices 1 are also provided here, each with its own manipulator 10 and a storage arrangement 11 located on the respective manipulator 10 and a transfer device 12 and a machine bearing 13, in particular close to the machine.
- the two devices 1 can work alternately in order to achieve a high cycle output for the edging of panels.
- the device 1 of all expansion stages can be equipped with at least one reading module, which is not shown in detail.
- the reading module can be arranged in the area of the storage unit 3 . It is also conceivable that each storage location 7 of the storage unit 3 is equipped with such a reading module.
- a reading module can also be arranged at other locations, for example on the base frame 2 or the storage arrangement 11 or one or a plurality of their storage locations.
- the goal is the automated transmission of information about the respective edge bands 4 or cassettes 4a that are currently located in the storage unit 3 or have been removed from it or have just been added.
- the edge bands 4 or cassettes 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 be designed as such.
- the reading module or the reading modules are set up to correspond with the transmission modules. This can be done in one direction or in both directions, which means the mere reading of data or a combination of reading and writing of data by the read module to a transmitter module.
- the device 1 according to the invention can advantageously include at least one interface, which is not shown in detail here. This interface is then designed to be coupled to at least one other component or machine, in particular mechanically and/or in terms of data transmission. the. In this way, all the components or machines of an edging system 8 can be controlled via a corresponding controller.
- FIGS. 8 and 9 show the device 1 shown in FIG. 1 and shown only as an example in the other FIGS. In order to avoid repetition and for better clarity, only some of the reference numbers can be seen here, since the same parts correspond to the parts already shown in FIGS. 1 to 7.
- the main difference between the variants shown in FIGS. 8 and 9 lies in the different shape of the base frame 2 carrying the storage unit 3.
- the frames 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 parallel to the horizontal X.
- the base frame 2 shown in FIGS. 1 and 3 to 7 has a total of four rectangular tubes connecting each of its two frames located on one side 2a, 2b, which are located there between the opposite corners of said frames parallel to the horizontal X.
- those rectangular tubes connecting the frames lie one above the other in relation to the vertical Z, so that the base frame 2 is essentially U-shaped in its top view, which is not shown in detail here.
- Fig. 9 shows an embodiment variant, the view of the base frame 2 is to be designated as L-shaped.
- the base frame 2 comes with a 2a on only one side located frame, while the opposite side 2b is virtually frameless.
- the lower area of the base frame 2 made up of rectangular tubes is closed.
- the two rectangular tubes running parallel to the horizontal X each extend away from a lower corner of the frame located on side 2a, these being connected to one another at the end by a rectangular tube running parallel to the spacing direction Y.
- a closed, essentially rectangular shape results.
- the profiles referred to as rectangular tubes in the context of the description can also—unlike what can be seen in FIGS. 1 to 9—have 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.
- FIGS. 10 and 11 A detail from an edging system according to the invention is shown in FIGS in which the device 1 according to the invention is arranged 3 in vertical direction direction Z at the height of the edging feed 9a, so that the edging tape 4 is drawn in from the edging roller or from the edging cassette 4a via the edging feed 9a into an edging feed line 15 by a suitable feed mechanism (not shown) and in the direction of a pressure unit 16, which is usually has at least one pressure roller 16a, is transported in order to be pressed there against the narrow side of a workpiece 17. As shown in Fig. 10, the edge roller or edge cassette 4a is in the working position.
- a cutting arrangement 14 is arranged on the edging machine 9 in the example in FIG.
- the cutting arrangement is preferably in the immediate vicinity of the edging roller or edging cassette 4a. Immediate proximity means that the cutting arrangement 14 should be arranged at least in the region of the end of the feed path 15 remote from the pressing device 16 . As in the example in FIG. 10 , this can be achieved in that the cutting arrangement 14 is arranged at or in the area of the end of the feed path 15 facing the device 1 .
- a cutting arrangement 14' or 14" can also be arranged on the device 1 itself, so that the cutting arrangement 14' or 14'' can then be located in the area of the edge feed 9a on the section of the device 1 or of the base frame 2 or the storage unit 3.
- the cutting arrangement 14' or 14'' is arranged in the area of the device 1 in such a way that when the edging roller is designed as an edging cassette 4a in the Is able to separate the edging tape 4 at a point that is still within the edging cassette 4a—this cutting position is denoted by P2 in FIG. 11—or outside of the edging cassette 4a. This cutting position is denoted by P2 in FIG. 11 as an example.
- the alternative or supplementary The final arrangement of the cutting assembly 14 on the edging machine 9 or a stand (not shown) between the edging machine 9 and the device 1 separates the edge band 4 at a cutting position P1. Basically applies to each of the cutting arrangements 14, 14 ', 14 "that these as
- Knife can be formed, which can be displaced into the transport path of the edging strip 14 in order to cut through the edging strip at position P1 or P2, in order to separate a severed edging strip to be attached to a workpiece 17 from the rest of the edging roll.
- the advantage of arranging the cutting arrangement in the area of the working position of the edging roll or edging cassette 4a is that the edging tape does not have to be pulled back over the entire feed path 15 before changing to another edging roll or another edging cassette 4a, i.e. onto the roll has to be wound up or pulled back into the edge cassette 4a, but is already cut off in such a way that the step of pulling back or rolling up again can be saved. This saves time and it is possible to switch to a different edgeband.
- the cutting arrangement can already cut off the edging tape 4 within an edging cassette 4a, as is indicated, for example, by the positions of the cutting arrangements 14' and 14'', since the associated edging cassette 4a then turns off immediately after cutting the working position can be brought into a storage position and by moving the storage unit 3 another edging cassette can be brought into the working position.
