Technical Field

The invention relates to a processing device, in particular for plate-shaped and/or rod-shaped wooden workpieces.

Background

Planing devices for wooden workpieces are known from the prior art. Here, a wooden workpiece in a plate or bar shape is usually shaved. Here, the plate-shaped workpiece is a rather flat, elongated workpiece and has a dimension in the width direction which is several times larger than the dimension in the depth or thickness direction. Further, the rod-like workpiece is a relatively long workpiece and has a dimension in width approximately equivalent to a dimension in a depth or thickness direction.

Such a planing device performs planing on a workpiece on at least one side along a feed direction, along which the workpiece is conveyed to the planing device. After planing, the workpiece is usually removed from the planing device by a worker, stored and, if necessary, supplied by the worker to a further production or processing step provided in a further device located downstream. Here, the planed workpiece may be damaged or erroneously fed to another processing device, which may result in defective products and thus increase costs, which is to be avoided.

Disclosure of Invention

The object of the present invention is to provide a processing device which is improved with respect to the prior art but which is simple and inexpensive. The object of the invention is also to provide a method for machining workpieces with a machining device, which method allows simple and cost-effective machining.

The object with regard to the processing device is solved by the features of claim 1.

One exemplary embodiment of the invention relates to a machining device, in particular for plate-shaped or bar-shaped wooden workpieces, having at least one tool for profiling at least one side of the workpiece in a cutting manner, having a conveying device for generating a relative movement between the workpiece and the at least one tool in order to machine the workpiece with the at least one tool, and having a device for applying material to the workpiece, wherein the device for applying material to the workpiece is arranged in particular in the conveying direction of the conveying device downstream of the at least one tool for profiling.

The feature "wooden workpiece" here particularly refers to a workpiece made of solid wood, such as a wooden beam or a wooden board made of solid wood. If desired, wood-like materials can also be used, which at least partially comprise wood, such as plywood, multi-component materials or sandwich materials.

The tool is, for example, a planing tool, a milling tool and/or a grinding tool. Accordingly, the machining device can be a planing device and/or a milling device and/or a grinding device. This also applies in general hereinafter without a corresponding recitation.

The transport device serves to generate a relative movement of the workpiece with respect to the at least one tool. Here, the workpiece can be transported and thereby displaced without the at least one tool being displaced. Alternatively, it is also possible that the at least one tool is transported and thus displaced, while the workpiece is not displaced. Finally, both the workpiece and the at least one tool may be displaced.

In an advantageous embodiment, the workpieces are therefore conveyed, in particular continuously, wherein the workpieces are profiled and subsequently covered with material applied to at least one surface of the workpiece in a workpiece flow.

According to the concept according to the invention, it is advantageous in one embodiment if the conveying device conveys the workpiece in a conveying direction and/or if the conveying device conveys the at least one tool.

It is also advantageous if the conveying device guides the workpiece in the direction of the device for applying material and/or guides the workpiece past the device for applying material in order to apply material to the workpiece.

It is also advantageous if the conveying device has a fastening element for fastening the workpiece during the conveying and/or during the machining of at least one side of the workpiece.

In this case, it is particularly preferred if the workpiece is machined on up to four sides by means of a planing device, a four-sided planing device and/or a milling device and/or a grinding device. Thus, the workpiece may be machined, such as machined, on one side or on more than one side, as desired. Preferably, the workpiece is profiled in a cutting manner on all four sides. For this purpose, the planing device preferably has rotary tools, such as knife shafts, by means of which the workpiece is profiled in a cutting manner. Thus, at least one such cutter shaft can be provided for each side face in order to be able to contour the respective side face in a cutting manner as intended. In this context, planing means the production of smooth, in particular flat, surfaces, and milling means the production of undulating surfaces with elevations and/or depressions, such as grooves.

It is also particularly advantageous if the device for applying material to a workpiece has a strip application device, by means of which at least one strip can be applied to the workpiece. Thus, for example, an adhesive or cover tape or the like can be applied to the workpiece, in particular along the entire length of the workpiece. Here, the adhesive or cover tape or other tape can be self-adhesive or for this purpose an adhesive can be applied before the tape is applied. The adhesive may be sprayed, rolled or otherwise applied, for example.

It is particularly advantageous if the strip is an adhesive strip or a cover strip. By means of the adhesive strip, for example, a sheet, such as a glass sheet, can be adhered to the workpiece, in particular in the case of workpieces which are joined together with other workpieces to form a window frame. The adhesive tape may be, for example, a single-sided or double-sided adhesive tape.

According to a further aspect of the invention, it is also advantageous if the device for applying material has a device by means of which a primer and/or an adhesive or the like can be applied to the workpiece. For this purpose, the primer material to be applied can be applied, for example, by spraying, rolling or otherwise as a first layer or as a base coat or adhesion promoter, and then subsequently another material, such as an adhesive or a tape, is applied.

In one embodiment, it is particularly advantageous to provide optional drying support means, i.e. heating means and/or blowers or the like, by means of which the applied material, such as base coats, primers or the like, can be dried more quickly. The heating device can be an air heating device, an infrared heating device, a heat radiator and/or a heating plate, etc., which dries the material on the workpiece more quickly. For this purpose, a blower may also be provided, which, for example, delivers hot air to the workpiece in order to accelerate the drying.

It is also advantageous if a cleaning device for cleaning the workpiece is provided in the workpiece flow between the planing device and the device for applying material. Thus, the workpiece can be freed from debris, for example, before further processing. Thus, the application quality of the further material can be improved.

It is also particularly advantageous here if the cleaning device has a blowing nozzle, a suction device and/or a brushing device or the like. The blowing nozzle can easily remove very fine particles, while the brushing device can also easily remove larger portions. Instead of the blowing nozzles, suction devices can also advantageously be provided.

It is also advantageous for the strip processing if the strip application device has a shearing device for shearing the strip. The strip can therefore preferably be cut in a length-optimized manner, so that the strip is applied over the length, as required. This eliminates additional subsequent processing and reduces costs.

According to a further concept of the invention, it is advantageous if a workpiece storage device is provided in the workpiece flow between the at least one tool and the device for applying material for storing at least one workpiece or a plurality of workpieces. The storage of the workpieces can thus be carried out, if advantageous, for example in the case of a strip change or a medium change or maintenance or the like, i.e. in particular in the case of a processing plant which is produced more quickly than the downstream devices for applying material.

It is also advantageous if the machining device has a machining width for machining, in particular for planing and/or milling, so that a maximum workpiece width of 450mm and/or a maximum machining thickness of 350mm is possible.

It is also advantageous if the workpieces to be machined are preferably rod-shaped workpieces, their workpiece width being up to 300mm and/or their thickness being up to 150 mm.

The object with regard to the method is solved by the features of claim 15.

An embodiment of the invention relates to a method for machining a workpiece with a machining device, in particular according to one of the preceding claims, in which method the workpiece is profiled by at least one tool on at least one side by cutting and subsequently, in particular in a workpiece flow, material is applied to the workpiece by a material application device.

It is advantageous here to carry out the cleaning after the profiling, in particular before the application of the material to the workpiece. This makes it easy to apply the material in a permanent manner and improves the quality of the fixing.

It is also advantageous if, after the contour machining of the workpieces, the workpieces are stored in a workpiece storage device, wherein, after removal of a workpiece or the workpiece, material is applied to the removed workpiece.

Further advantageous embodiments are described by the following description of the figures and by the dependent claims.

Drawings

The invention is explained in detail below on the basis of at least one embodiment according to the figures of the drawing.

In the drawings:

fig. 1 shows a schematic view of a processing device according to the invention.

Detailed Description

Fig. 1 shows a schematic representation of a machining device 1, in particular for plate-shaped or rod-shaped workpieces 10, in particular made of wood. According to the concept according to the invention, the plate-shaped workpiece 10 is a comparatively flat, elongate workpiece 10 and has a dimension in the width direction which is several times greater than the dimension in the depth or thickness direction. However, it is also possible to machine bar-shaped workpieces 10, for example strips for windows or door frames or the like, which are designed as elongate workpieces 10 and have a dimension in the width direction which corresponds to the dimension in the depth or thickness direction. Generally, the rod-like workpiece 10 is longer in the length direction than in the width direction and/or in the depth direction. The workpiece is preferably made of solid wood or a wood-like material. Here, it is particularly preferred that the workpiece is a rod-shaped workpiece, in particular for window structures. Preferably, these workpieces have a width of up to about 300mm and a thickness of up to about 150 mm.

In one exemplary embodiment, the processing device 1 has a transport device 2 for transporting the workpiece 10, wherein the transport device 2 optionally has fastening elements for fastening the workpiece 10 during transport and/or during processing of at least one side 11 of the workpiece 10. The respective workpiece 10 can therefore be transported by the machining device 1 and advantageously fixed for the cutting process. Replacement of the fastening elements can also be provided for machining all side surfaces 11.

The conveying device 2 advantageously has rollers 18, which convey the workpieces 10 in a conveying direction. The rollers 18 are preferably located above and/or below and preferably act vertically on the workpiece. Advantageously, laterally situated rollers 18 are also provided, which preferably act in the horizontal direction. Instead of or in addition to the rollers 18, other conveying elements, such as conveyor belts or the like, can also be provided.

Alternatively, the conveying device 2 also conveys the at least one tool 3 or both the workpiece 10 and the at least one tool 3.

The conveying device 2 thus effects a relative movement between the workpiece 10 and the at least one tool 3 in order to machine the workpiece 10 with the at least one tool 3.

The machining device 1 accordingly has at least one tool 3 for the contour machining or machining of a workpiece 10 in a cutting manner. The workpiece 10 can be machined on up to four sides, for example, by a planing device, a four-sided planing and/or planing device 4, a milling device and/or a grinding device, which have various different tools 3 for machining the desired side 11 of the workpiece 10.

As can be seen from fig. 1, a device 5 for applying material to a workpiece 10 is provided after the at least one tool 3 for contour machining.

Here, the conveying device 2 or a section of the conveying device 2 for the workpiece 10 in particular also traverses the device 5 for applying material and conveys the workpiece 10 in the direction of the device 5 for applying material and/or passes the workpiece past the device 5 for applying material. Thus, the material to be applied can be applied during the movement of the workpiece 10, resulting in efficient machining. Alternatively, the workpiece 10 may also be placed in a stationary state before it is conveyed further.

The device 5 for applying material to the workpiece 10 can be designed as a strip application device 6 or have such a device. With such a strip application device 6, at least one prefabricated strip 7 can advantageously be applied to the workpiece 10. The strip 7 can be an adhesive or cover strip or another strip. As an adhesive tape, the tape may be single-sided or double-sided adhesive. The strip application device 6 advantageously has a cutting device 16 for cutting the strip 7, so that the strip 7 can be cut to the desired length. The strip may for example be self-adhesive and/or it may also be coated with an adhesive. The adhesive may also be applied independently of the tape or without the tape. The adhesive can be applied by rolling, spraying, etc., particularly in the device 8 prior to attachment.

The device 5 for applying material advantageously optionally has a device 8 by means of which a medium, such as a primer, an adhesive or the like, can be applied to the workpiece 10. The media may be coated by rolling, spraying, etc. The device 8 is optionally arranged in the direction of the workpiece flow 12 upstream of the strip application device 6 or without such a strip application device. In this way, a particularly further medium can be applied before or also without the application of the strip. Alternatively, the bonding surface to which the adhesive or self-adhesive material is to be applied may be treated beforehand with a wood preservative or in another manner.

In one embodiment, it is particularly advantageous if an optional drying support 19 is also provided, which is preferably designed as a heating device and/or a blower or the like, by means of which the material applied by means of the device 8, such as a base coat, a primer or the like, can be dried more quickly. The heating device can be an air heating device, an infrared heating device, a heat radiator and/or a heating plate, etc., which accelerate the drying of the material on the workpiece. For this purpose, a blower may also be provided, which, for example, delivers hot air to the workpiece in order to accelerate the drying.

Fig. 1 also shows that a cleaning device 9 is provided in the workpiece flow between the machining or planing device 13 with the tool 3 and the device 5 for applying material, which cleaning device serves to clean the workpiece 10 after the workpiece 10 has been cut in the machining or planing device 13 and before the workpiece 10 is coated with coating material. Here, the cleaning device 9 has a blowing nozzle 14, a suction device and/or a brushing device 15, etc. The blower nozzles 14 blow air, for example compressed air, onto the workpiece 10 and thus clean the surface of the workpiece 10, in particular remove fine constituents, such as dust or swarf. The brushing arrangement 15 brushes the workpiece and thus cleans it, removing coarse components.

With such a machining device, a method for machining a workpiece 10 can be carried out, in which method the workpiece is profiled in a cutting manner on at least one side 11 in a machining or planing device 13 and subsequently a material is applied to the workpiece 10 in a workpiece flow by means of the device 5 for applying material. This is preferably and optionally carried out in a stream of workpieces with substantially continuous transport of the workpieces 10. Alternatively, a workpiece storage device 17 can also be connected in between, in which the workpieces 10 can be stored in between. The workpiece storage device 17 may be optional. If present, the workpieces 10 can be stored in the workpiece storage device if required, or alternatively can be bypassed if required, so that the finished workpieces 10 can be transported on directly without intermediate storage.

In this method, it is particularly preferred to perform the cleaning after the contour machining of the workpiece 10, in particular before applying the material to the workpiece 10. This improves the quality of the material application and in particular the adhesion of the material on the workpiece 10 over a larger time interval.

The machining or planing device 13, the optional cleaning device 9 and the device 5 for applying material accordingly form an integral unit in which the conveying device 2 conveys the workpiece 10 to be machined and to be coated with material, in particular through the entire machining device. The worker places the workpiece 10 into the processing device 1 on the entry side and performs the profiling first and the covering material is then removed again on the exit side.

But this can in principle also be automated. There is no intervention between the profiling process and the covering material process during normal production.

The application of material, i.e. for example adhesive tape and/or cover tape, can preferably take place in preformed grooves of the workpiece 10.

The conveying device 2 can be designed as a continuous or segmented conveyor, each segment being used for a corresponding conveyance through the processing or shaving device 13, the cleaning device 9, the workpiece storage device and/or the device 5 for applying material. For this purpose, for example, rollers 18 provided can be provided in order to be able to convey the workpiece through the processing device.

The processing device 1 and/or the cleaning device 9 and/or the device 5 for applying material are preferably arranged in a protected space or in a protective housing, if necessary under ambient conditions which lead to a defined, in particular temperature, air humidity, etc.

The adhesive tape according to the invention may be, for example, a Polyethylene (PE) foam adhesive tape and/or an acrylate foam adhesive tape or a PE film adhesive tape.

Preferably, however, and optionally, the workpiece does not have an edge band or other surface coating, which may be understood as a covering layer and forms a durable active surface. The materials applied according to the invention are preferably adhesive tapes, adhesives and base coats/primers or the like, see above.

It is also preferred that the workpiece can optionally be machined on all sides, for example by planing and/or milling and/or that the workpiece can be coated on all sides with the material to be coated. All surfaces here mean in particular the four long side surfaces of the workpiece and preferably not in particular the two opposite end surfaces of the workpiece.
