Description

BRIEF DESCRIPTION OF THE FIGURES OF THE DRAWING

[0030] The invention, based on at least one exemplary embodiment, will be explained in more detail hereunder by means of the FIGURES of the drawing in which:

[0031] FIG. 1 shows a schematic view of a machining device according to the invention.

PREFERRED EMBODIMENT OF THE INVENTION

[0032] FIG. 1 in a schematic illustration shows a machining device 1, in particular for board-shaped or bar-shaped workpieces 10, in particular from lumber. According to the concept according to the invention, board-shaped workpieces 10 tend to be flat elongate workpieces 10 having an extent in the width direction which is larger by a multiple than the extent in the depth or thickness direction, respectively. Workpieces 10 that tend to be bar-shaped can also be processed, such as strips for windows or door frames, etc., for example, which tend be configured as elongate workpieces 10 having an extent in the width direction which corresponds approximately to an extent in the depth or thickness direction, respectively. The bar-shaped workpieces 10 in the longitudinal direction are typically longer than in the width direction and/or in the depth direction. The workpieces are preferably made from solid lumber or from a lumber-like material. It is particularly preferable herein when the workpieces are bar-shaped workpieces in particular for the construction of windows. The workpieces are preferably approximately up to 300 mm in width and approximately up to 150 mm in thickness.

[0033] The machining installation 1 in one exemplary embodiment is equipped with a transport installation 2 for transporting workpieces 10, wherein the transport installation 2 optionally has holding means for holding the workpiece 10 during the transportation and/or during machining of at least one of the lateral faces 11 of the workpiece 10. On account thereof, the respective workpiece 10 can be transported through the machining device 1 and advantageously held for the subtractive machining. For machining all lateral faces 11, a changeover of the holding means can also be provided.

[0034] The transport installation 2 advantageously has rolls 18 which transport a workpiece 10 in the transporting direction. Said rolls 18 preferably lie above and/or below and preferably act vertically on a workpiece. Laterally disposed rolls 18 which preferably act horizontally are also advantageously provided. Alternatively or additionally to the rolls 18, other transport means such as a transport belt, etc., can also be provided.

[0035] Alternatively, the transport installation 2 can also transport the at least one tool 3, or both the workpiece 10 as well as at least one tool 3, respectively.

[0036] On account thereof, the transport installation 2 causes a relative movement between the workpiece 10 and the at least one tool to 3 be generated for machining the workpiece 10 by way of the at least one tool 3.

[0037] The machining device 1 accordingly has at least one tool 3 for subtractively contouring or machining, respectively, the workpiece 10. The machining of the workpiece 10 herein can take place on up to four lateral faces 11, for example by means of a planing installation, a four-side molder and/or trenching installation 4, a routing installation and/or a sanding installation, which have/has various tools 3 for machining the desired lateral faces 11 of the workpiece 10.

[0038] It can be seen in FIG. 1 that an installation 5 for applying material to the workpiece 10 is disposed downstream of the at least one tool 3 for contouring.

[0039] The transport installation 2, or a segment of the transport installation 2 for the workpiece 10, herein traverses in particular also the installation 5 for applying material, and transports the workpiece 10 toward the installation 5 for applying material and/or past the installation 5 for applying material. On account thereof, the material to be applied can be applied during the movement of the workpiece 10 such that efficient processing can take place. Alternatively, the workpiece 10 can also be brought to a standstill before said workpiece 10 is transported onward.

[0040] The installation 5 for applying material to the workpiece 10 can be configured as a tape application installation 6, or comprise such a tape application installation 6. At least one prefabricated tape 7 can advantageously be applied to the workpiece 10 by way of such a tape application installation 6. The tape 7 herein can be an adhesive tape or a masking tape or another tape. Said tape as an adhesive tape can be adhesive on one side or both sides. The tape application installation 6 advantageously has a cross-cut installation 16 for cross-cutting the tape 7 so as to be able to cut the tape 7 to the required length. The tape can be self-adhesive, for example, and/or an adhesive can also be applied. An adhesive can also be applied independently of a tape or else without a tape. Said adhesive can be applied by rollers, rolls, sprays, etc., in particular in an upstream installation 8.

[0041] Advantageously, the installation 5 for applying material optionally has the installation 8 by means of which a medium such as, for example, a primer, an adhesive, etc., is capable of being applied to the workpiece 10. The medium can be applied by rollers, rolls, sprays, etc. Said installation 8 is optionally disposed upstream of the tape application installation 6 in the direction 12 of the workpiece flow, or else can be provided without such a tape application installation. On account thereof, an in particular further medium can be applied, in particular pre-applied, prior to the application of a tape, or else without the application of a tape. An adhesive bonding face to which an adhesive or a self-adhesive material is applied can optionally be pre-treated with a wood protection agent or in another manner.

[0042] In the case of an exemplary embodiment it is particularly advantageous when an optional drying facilitation installation 19 which is preferably configured as a heater and/or a fan, etc., and by means of which the applied material such as, for example a base coat, a primer, etc., can be more rapidly dried by means of the installation 8, is also provided. The heater herein can be an air heater, an infrared heater, a heating radiator and/or a hotplate, etc., which accelerate/accelerates the drying of the material on the workpiece. To this end, a fan which transports, for example, hot air to the workpiece in order for the drying to be accelerated, can furthermore also be provided.

[0043] FIG. 1 furthermore shows that a cleaning installation 9 for cleaning the workpiece 10 after said workpiece 10 has been subtractively machined in the machining installation or planing installation 13 and before said workpiece 10 is provided with material, is disposed in the workpiece flow between the machining installation or planing installation 13 having the tools 3 and the installation 5 for applying material. The cleaning installation 9 herein can have a blower nozzle 14, suction installation, and/or a brush installation 15, etc. For example, the blower nozzle 14 blows air such as, for example, compressed air, onto the workpiece 10 and thus cleans the surface of the workpiece 10 in particular in terms of fine elements such as dust or shavings. The brush installation 15 brushes the workpiece and thus cleans the latter, in particular in terms of comparatively coarse elements.

[0044] By way of such a machining device it is possible for a method for machining a workpiece 10 to be carried out in which a workpiece is subtractively contoured in a machining installation or a planing installation 13 on at least one lateral face 11 and subsequently in the workpiece flow a material is applied to the workpiece 10 by means of an installation 5 for applying material on the workpiece 10. This is preferably and optionally performed in workpiece flow at a substantially continuous transportation of the workpiece 10. Alternatively, a workpiece store 17 in which workpieces 10 can be temporarily stored can be interposed. Said workpiece store 17 can be optional. If said workpiece store 17 is present, workpieces 10 can be stored therein on demand; alternatively, said workpiece store 17 can also be bypassed on demand such that the machined workpieces 10 are conveyed onward directly without any intermediate storage.

[0045] In the case of the method it is particularly preferable when cleaning is performed after the contouring of the workpiece 10, in particular before material is applied to the workpiece 10. This enhances the quality of the application of material, in particular the adhesive capability of the material on the workpiece 10 over a comparatively long period of time.

[0046] The machining installation or the planing installation 13, the optional cleaning installation 9, and the installation 5 for applying material accordingly form a unit in which the transport installation 2 transports the workpiece 10 to be machined and to be provided with material in particular through the entire machining device. An operative places the workpiece 10 into the machining device 1 at the infeed side and retrieves said workpiece 10 again at the outfeed side, said workpiece 10 first having been contoured and provided with material. However, in principle this can also be performed in an automated manner. No intervention in the normal production process takes place between the contouring and the provision with material.

[0047] The application of material, thus of adhesive tapes and/or of masking tapes, for example, can preferably take place in pre-cut rabbets of the workpiece 10.

[0048] The transport installation 2 can be embodied so as to be contiguous or in segments for the respective transportation through the machining installation or planing installation 13, the cleaning installation 9, the workpiece store and/or the installation 5 for applying material. To this end, the provided rolls 18 can be disposed in a corresponding manner so as to be able to transport a workpiece 10 through the machining device, for example.

[0049] The machining device 1 and/or the cleaning installation and/or the installation 5 for applying material are/is preferably disposed in a protected room or in a protective housing, optionally while generating defined ambient conditions, in particular in terms of temperature, air humidity, etc.

[0050] An adhesive tape according to the invention can be, for example, a polyethylene (PE) foam adhesive tape and/or an acrylate foam adhesive tape or a PE film adhesive tape.

[0051] However, the workpieces are preferably and optionally not provided with an edge tape or any other surface coating which is understood to be a lamination and configures a permanent usable surface. The material applied according to the invention is preferably an adhesive tape, an adhesive, and a base coat/primer, or similar, see above.

[0052] It is also preferable when the workpiece can optionally be machined such as planed and/or routed on all sides, and/or the workpiece can be provided with the material to be applied on all sides. All sides herein means in particular the four long sides of the workpiece and preferably in particular not the two mutually opposite end sides of the workpiece.
