Description

Technical area

The present invention relates to a machine system for applying band-shaped, preferably in the form of coils present edge band material to workpieces, which preferably at least partially made of wood, wood materials, plastic or the like.

State of the art

Machine systems of the type mentioned are increasingly geared to be able to use different edgeband material for different workpieces in addition to a quick feeding of the edge strip material to the workpiece and applying the edge strip material to the workpiece. In addition, a high degree of flexibility is required for a high throughput.

In existing machine systems, edge band magazines are provided on the machine system for this purpose, which can store and provide a plurality of different edge band materials. For example, the edge band materials are wound up and stored as roll-shaped coils. The wraps are widely distributed in cassettes so that they have increased stability and handleability. The cassettes have, for example, an axis on which the edge band material is wound up. Via a plurality of edge band channels in the edge band magazine, the individual edge band materials are fed to a coating unit for applying and pressing the edge band material to the workpiece.

A disadvantage of the known machine systems that the edge band magazines take up a lot of space due to the numerous edge band channels, sometimes over 70 edge band channels. Furthermore, the device and adjustment of such edge band magazine due to the numerous edge band channels is time consuming and expensive. However, this contradicts the desire of the production system using the machine system for a compact machine system with a small space requirement that can be used and configured quickly.

Presentation of the invention

It is therefore an object of the present invention to provide a machine system for attaching band-shaped present edgeband material to workpieces that preferably at least partially made of wood, wood materials, plastic or the like, to provide that is spatially compact and easy to set up.

According to the invention, this object is achieved by a machine system and a method having the features of the independent claims. Preferred embodiments are given in the dependent claims.

According to the invention, a machine system for attaching band-shaped, preferably in the form of winding present edgeband material, for example, plate-shaped workpieces, which preferably at least partially made of wood, wood materials, plastic or the like, a coating unit for applying and pressing the edge strip material to the plate-shaped workpiece. The coating unit leads, for example before the pressing of the edge material adhesive to the workpiece or edge material. It is also possible that the coating unit, the edge material or the Preheated workpiece before or during pressing, to bond the edge material with the workpiece adhesive.

On the coating unit, a magazine unit is arranged to transport or buffer the edge band material. The edge material is preferably fed to an edge channel in the magazine unit. As a result, the magazine unit can be made simple and spatially compact on the coating unit. However, it is also possible to provide a plurality of edge channels for simultaneously receiving a plurality of edge bands, which allows greater manufacturing flexibility with regard to the use of different edge bands.

A feeder is provided for feeding the edge strip material to the magazine unit. The feeder is arranged to take over the edge strip material from a transport device which feeds the edge strip material from a store for edge strip material and to transfer it to the magazine unit. The transport device thus has the function to promote the edge band material from the memory to the feeder.

The memory is designed such that several edge band materials can be stored. In this case, the edge strip materials can be provided as a strip (eg stacked), as a roll or in any other arrangement. For example, several reels may be arranged substantially horizontally next to each other in a vertical orientation. The orientations horizontally and vertically relate to orientations when the machine system is arranged ready for operation. The rolls are then oriented vertically when the axis of rotational symmetry of an assumed cylindrical winding core, on which the edge strip material is wound, extends substantially horizontally. Preferably, the winding are arranged vertically analog Drawers arranged parallel to each other. This results in a particularly compact arrangement of the winding. These can then be removed in a drawer-like manner, one by one, individually from the row of coils without having to change the position of the coils which are not required. Furthermore, in this arrangement, the winding material can be unwound simultaneously from a plurality of windings and removed in a straight line without crossing the directions of the webs of material stored.

According to one embodiment, the rolls are arranged in cassettes. As a result, the handling and accurate positioning of the edge strip material is facilitated as a winding. Regardless of the type of edge material and the amount of edge material present on the reel, the cassettes can be provided with standardized dimensions or handling geometries. An automated or mechanical insertion or replacement of the cassettes with the coils arranged therein is thus facilitated.

According to one embodiment, the transport device has a capping unit for separating edge band material. The capping unit allows edge banding material that has been removed from the storage to be used for coating workpieces to be selectively severed. The capping unit has, for example, a scissors tool, a laser-beam cutting tool or the like for separating the edge band material.

According to a further embodiment, the transport device has at least one circulating belt for entrainment of the edge strip material. The entrainment can be done for example by frictional engagement between the belt and the edge band material, but also by other mechanisms we force, magnets or the like. The belt makes it possible to promote the edge band material, for example by pressing this against the belt becomes. The resulting friction between the belt and the edge band material, this can be moved along a conveyor line. The course of the belt, which determines the conveyor line, can thereby be easily changed by the arrangement of guide rollers which guide or drive the belt. In this way it is technically easy to realize the transport route.

Preferably, the transport means comprises pressure means, preferably (e.g., bent) spring plates for pressing the edge band material against the circulating belt. The edge band material is guided between the belt and the pressure means, which press the edge band material to the belt. For curved or rounded pressure means (such as spring plates), these preferably lie with a rounding on the belt or on the edge strip material, whereby their load and wear is kept low. Further, the rounding or bending allows easy insertion of the edgeband material between the belts and the pressure means without the edgeband material getting caught on the pressure means. The result is a tapered gap into which the edge band material is introduced.

According to one embodiment, the transport device has a transport element for a loose end of the edge strip material in order to introduce it into the transport device. The transport element pushes or pulls the loose end, for example, to the belt of the transport device, so that the loose end comes to rest on the belt. As a result, a manual "threading" of a loose end of a roll arranged in the storage in the transport device by an operator is not required, which increases the reliability and reliability of the system. The transport element has, for example, a gripper or a vacuum suction element for holding the loose End on, which can be moved pivotally or linearly in the direction of the belt.

The memory can be designed in the context of the invention in different ways, sometimes also multi-level, in particular two-storey, so that several edge band materials can be stored one above the other. This allows more edge band materials to be arranged per base area of the memory than if the edge band materials are arranged side by side only in the plane. As a result, the overall machine system can be made more compact, which reduces its space requirement.

According to one aspect, the transport device or else the store can be moved vertically in order to align the required edge band material in the store in the height relative to the transport device. Particularly in multi-storey trained memory height adjustment between the transport device and arranged in the memory edge strip materials is advantageous to position the edge strip material regardless of its vertical position in the memory always equal to the transport device. As a result, the transfer of edge strip material to the transport device can be kept simple.

According to a further aspect, the transport device has a plurality of feed channels for simultaneously receiving a plurality of edge strip materials arranged in the store. Several edge bands can be picked up at the same time. The transport device then preferably also has a plurality of belts for transporting the edge material strips. As a result, a plurality of edge material strips can be fed simultaneously to the coating unit. This allows processing different edge material bands simultaneously or in rapid succession.

In accordance with a further aspect, the transport device or else the store is movable horizontally in order to position the edge band materials relative to the transport device for pick-up by the transport device. The transfer of Kantenmaterialbändern to the transport device can be particularly easily performed when it takes place at a certain point on the transport device. However, since the edge band materials are preferably arranged side by side, forming a row, this can be realized by positioning a defined receiving location for edge band materials on the transport means on the coil from which edge band material is to be picked up. The horizontal displaceability of transport device or storage is realized for example by means of a guide system, rail system or by rollers.

According to a further aspect, an additional magazine for storing and supplying edge band material to the magazine unit is provided. For example, this additional magazine can store frequently needed edge band material. As a result, this can be made available very quickly for a coating process.

Detailed description of preferred embodiments

The invention will be explained in more detail below with reference to embodiments with reference to the accompanying figures of the drawings. In the figures, the same reference numerals designate the same or functionally identical components, unless indicated otherwise.

Fig. 1 shows a schematic representation of a machine system 1 according to the invention according to a first embodiment. Workpieces 2 (in particular plate-shaped workpieces) are shown spaced apart from each other at the top right in the image. In this exemplary embodiment, these are fed from the right to the machine system 1, in order in particular to coat their narrow workpiece surfaces with edge strip material 5. The edge band material 5 can be wound up, ie provided in the form of so-called windings 6 on the machine system 1 and unwound from the windings 6 for the coating process. However, it is also possible, the edge band material 5 in the form of / if necessary. prefabricated) strips, for example can be stacked.

In the present embodiment, the coils 6 are arranged in cassettes 7. As a result, the handling and accurate positioning of the edge strip material 5 as a winding 6 is facilitated. The reels 6 are arranged vertically in this embodiment. Standing here means that when the edge band material 5 is wound around a cylindrical core, the coils 6 could roll on a horizontal plane. Several reels 6 are arranged side by side in a memory 40 for winding 6. That If the edge band material 5 of the winding 6 is wound onto a cylindrical core, then the rotational symmetry axes of the cylinders run substantially parallel to one another.

A transport device 30 is arranged next to the storage 40 in order to transport away edge band material 5 unwound from one or more windings 6 and to transfer them to a feed device 20. It should be noted that feeder 20 and transport device 30 may also be formed by a common unit. The transport device 30 has in this embodiment, a plurality of feed channels 39 for simultaneously receiving edge strip material 5 of a plurality of coils 6, which are arranged in the memory 40 on. The transport device 30 has in this embodiment, a circulating belt 34 which forms a transport path for the edge strip material 5. In this embodiment, spring plates 36 are provided for pressing the edge band material 5 on the circulating belt 34. As a result, the edge band material 5 can be taken along by friction with the belt 34 and thus transported. Of course, the edge band material 5 can also be pressed against the belt 34 in other ways, for example by means of rollers. Likewise, the belt itself may be resiliently formed or stored.

The machine system 1 further has a coating unit 12 for applying and pressing the edge strip material 5 to the plate-shaped workpiece 2. On the coating unit 12, a magazine unit 10 for buffering and transporting the edge strip material is arranged. The coating unit 12 receives the edge band material 5 to be processed from the magazine unit 10. The magazine unit 10 in this exemplary embodiment has a single-channel structure. Thus, a strand of edge strip material 5 is fed into a feed channel. This simple structure is made possible by the rapid delivery of a wide variety of edge banding materials 5 from the storage 40 via the transport device 30. Of course, the magazine unit 10 can also be multi-channeled and thus allow the feeding of a plurality of edge strip material strands 5 at the same time, which can help to reduce the non-productive times when changing workpieces. The feed device 20 is set up to supply the edge band material 5 to the magazine unit 10.

Fig. 2 shows a schematic representation of a machine system 1 according to the invention according to a second embodiment. Much of the machine system elements are already in the description of FIG. 1 Therefore, to the description of which reference is made. In the embodiment according to FIG. 2 the transport device 30 additionally has a transport element 38 for a loose end 8 of the edgeband material 5 arranged as a winding 6 in order to introduce it into the transport device 30. The transport element 38 pushes or pulls the loose end 8, for example, to the belt 34 of the transport device 30, so that the loose end 8 comes to rest on the belt 34. As a result, manual "threading" of the loose end 8 of a roll 6 arranged in the storage 40 into the transport device 30 by an operator is not required. The transport element 38 has, for example a gripper or a vacuum suction element for holding the loose end 8, which can be moved pivotally or linearly movable in the direction of the belt 34.

Furthermore, in this exemplary embodiment, the transport device 30 has a capping unit 32 for separating edge strip material 5 from a winding 6. The capping unit 32 enables the edge banding material 5 unwound from a reel 6 in the storage 40 to be used for coating workpieces 2 to be separated reliably and accurately. The capping unit 32 is designed as a scissors tool in this embodiment.

Further, in this embodiment, an additional magazine 50 for storing and supplying edge band material 5 to the magazine unit 10 is provided. This additional magazine 50 can store, for example, frequently required edge band material 5 and provide this particularly quickly to the magazine unit. As a result, the high variant flexibility can be combined by the many edge bands 5 provided in the memory with a high throughput through the particularly rapid provision of frequently required edge bands 5.

Fig. 3 shows a schematic representation of a machine system 1 according to the invention according to a third embodiment. Much of the machine system elements are already in the description of FIG. 1 Therefore, to the description of which reference is made. According to the embodiment FIG. 3 the memory 40 is horizontally movable to position the reels 6 relative to the transport 30 for pick-up by the transport 30.

The transfer of Kantenmaterialbändern 5 to the transport device 30 can be particularly easily performed when they are at a certain point on the Transport device takes place. However, since the reels 6 are preferably arranged side by side, forming a row, this can be realized by positioning a defined receiving point for reel 6 on the transport device 30 on the reel, from which edge material tape 5 is to be received. The horizontal displaceability of the memory 40 is realized for example by means of a guide system, rail system or by rollers. It is also within the meaning of the present invention, the transport device 30 relative to the memory 40 to arrange displaced to achieve the stated effect of positioning of the coils 6 relative to the transport device 30.

Although the present invention has been described in terms of preferred embodiments herein, it is not limited thereto, but modifiable in a variety of ways.
