PROCESSING UNIT AND PROCESSING EQUIPMENT

Description

Technical area

[0001] The invention relates to a processing unit for a processing device and a processing device for processing workpieces. State of the art

[0002] Machining units with a so-called turret mechanism, which can accommodate multiple machining tools, are known from the prior art. Machining units with such a turret mechanism typically have only one machining exit in a defined direction, so that to perform a machining operation with a specific machining tool, the corresponding machining tool must be selectively moved to the position of the machining exit. Such a machining unit has complex mechanics and is comparatively cost-intensive.

[0003] A processing unit according to the preamble of claim 1 is disclosed in EP 2 868 431 A2. Description of the invention

[0004] The invention is based on the object of proposing a processing unit which has a simple structure and enables flexible processing of workpieces.

[0005] A processing unit is defined in claim 1. A processing device is defined in claim 5.

[0006] Subclaims relate to specific embodiments.The object is achieved by a processing unit for a processing device, in particular a wood processing device, comprising an aggregate body with a plurality of tool holders, each of which holds a processing tool for carrying out a processing operation on a workpiece, and a connecting device by means of which the aggregate body can be arranged on a drive device or a corresponding connection of the processing device, wherein at least three tool holders are provided, the respective longitudinal central axes of which are not aligned parallel to one another, wherein at least one of the tool holders is aligned with the longitudinal central axis at an angle of greater than + / -0° and less than + / -90° to a central axis of the connecting device or a pivot axis of the aggregate body and a processing output in the respective spatial direction is formed by each tool holder.

[0007] In this way, a very compact machining unit can be designed which enables variable machining of workpieces in different spatial directions. By arranging the at least three tool holders in such a way that their longitudinal center axes do not run parallel to one another, machining of workpieces in different spatial directions is possible. The respective tool holders can accommodate machining tools with different tool parameters or various machining tools, for example drilling tools, milling tools and / or sawing tools or even a measuring device and / or a blow-off nozzle or the like. This allows different machining processes to be carried out flexibly depending on the positioning of the machining unit relative to the workpiece.

[0008] For this purpose, the machining unit can be arranged on an actuating device of the machining device, by means of which an actuating movement, preferably a five-axis actuating movement, i.e., a translational actuating movement along the XYZ axes and a rotary actuating movement about additional axes A and C, can be controlled. The machining unit has a pivoting mechanism by means of which a pivoting movement of the machining tools relative to the connecting device can be controlled. In this way, in conjunction with the actuating device, a six-axis actuating movement, i.e., an additional rotary actuating movement about another axis, of the machining tools can be controlled.

[0009] Further embodiments of the processing unit are defined in the subclaims.

[0010] In addition, the object is achieved by a processing device for processing workpieces, in particular workpieces which are formed at least partially from wood, a wood-based material, plastic, composite material or the like, with a workpiece support for receiving at least one workpiece to be processed and with at least one processing unit for carrying out a processing operation on a workpiece to be processed, which is arranged to be movable relative to the workpiece, wherein the processing unit is designed according to one of the previously described embodiments.

Description of embodiments

[0012] The same reference numerals appearing in different figures indicate identical, corresponding, or functionally similar elements.

[0013] Figure 1 shows an embodiment of a processing device 10 for processing workpieces 11, which is preferably designed as a woodworking device. The processing device 10 is preferably designed as a stationary processing device. In this case, the workpiece 11 to be processed is positioned manually or mechanically on a workpiece support 12. The processing device 10 is preferably designed as a CNC-controlled processing device or as a CNC-controlled machining center.

[0014] The workpieces 11 to be machined are, in particular, those that are at least partially made of wood, wood-based materials, plastic, composite materials, or the like. Such workpieces are used, for example, in the field of furniture and construction element manufacturing. These workpieces can be a wide variety of materials, for example, solid wood or particle boards, lightweight panels, sandwich panels, or the like. However, the present invention is not limited to such workpieces.

[0015] For machining a workpiece 11, the machining device 10 comprises at least one machining unit 13, which is Figure 2according to an exemplary embodiment. To position the machining unit 13 relative to the workpiece 11 to be machined, the latter is arranged on an actuating device (not shown in detail). The actuating device can control a five-axis actuating movement of the machining unit 13, i.e., an actuating movement with five degrees of freedom. The five-axis actuating movement is formed by a translatory actuating movement along the XYZ axes and a rotary actuating movement about the A-axis and the C-axis.

[0016] The processing unit 13 has an aggregate body 14, on which a connection device 15 and several tool holders 16 are provided. By means of the connection device 15, the processing unit 13 can be connected to a corresponding connection of a drive device 17, as shown in Figure 2shown. The drive device 17 provides a drive for the processing tools 18 of the processing unit 13 or for a pivoting movement of the processing unit 13 described later. The drive device 17 can have an electric motor or a pneumatic drive. The drive device 17 is designed in particular as a spindle drive, for example a drilling spindle or milling spindle. The drive device 17 can in turn have a connection which can be attached, for example, to the actuating device of the processing device 10. Alternatively, the processing unit 13 can also be attached directly to a corresponding connection of the processing device 10 via the connection device 15.

[0017] The machining tools 18 are each accommodated in the tool holders 16. The tool holders 16 are arranged on the unit body 14 in a fixed position relative to the unit body 14. The tool holders 16 can be designed in various ways in order to simultaneously accommodate several similar and / or different machining tools 18. The machining tools 18 can be, for example, drilling tools, as in Figure 2 shown to saw tools, as shown in the Figures 8 to 10 shown, and / or milling tools. Likewise, one or more tool holders 16 can be configured to accommodate a measuring device (not shown in detail) and / or a blow-off nozzle. A force or torque transmission device is provided in the unit body 14, by means of which a torque introduced via the connection device 15 is transmitted to the machining tools 18 accommodated in the tool holders 16.

[0018] The aggregate body 14 is designed as a polyhedral body with multiple outer surfaces. The aggregate body 14 is designed as a polyhedron or a facet-shaped body. According to the Figures 2 to 10 In the illustrated embodiment of the processing unit 13, the unit body 14 has seven outer surfaces, on each of which at least one tool holder 16 is provided. The outer surfaces are arranged relative to one another such that the orthogonals of these outer surfaces are each aligned at a different angle to one another. In particular, at least three outer surfaces of the unit body are arranged relative to one another such that their orthogonals are not parallel to one another. The adjacent outer surfaces of the unit body 14 are at least partially aligned at an obtuse angle to one another. The adjacent outer surfaces of the unit body 14 can also be at least partially aligned at an oblique angle to one another.

[0019] In the embodiment of the aggregate body 14 according to Figure 2 an outer surface is formed which is aligned at right angles to a longitudinal axis 20 of the unit body 14 and on which three tool holders 16 are provided, each of which receives a machining tool 18 (drilling tool) axially to the longitudinal axis 20 of the unit body 14. The longitudinal axis 20 of the unit body 14 can be aligned axially to a central axis of the connecting device 15 or coincide with the central axis of the connecting device 15. These tool holders 16 can be arranged next to one another in a row in order to create a row of holes in the workpiece 11 in a simultaneous machining operation. Likewise, two or more than three tool holders 16 can be provided in a row or in a grid.

[0020] In addition, two further tool holders 16 are provided, each of which holds a machining tool 18 at a right angle to the longitudinal axis 20 of the unit body 14, wherein the tool holders 16 are arranged relative to one another in such a way that the respective machining tools 18 are oriented pointing in different spatial directions.

[0021] In addition, three tool holders 16 are provided on the unit body 14, which, compared to the tool holders 16 aligned axially and at right angles to the longitudinal axis 20 of the unit body 14, are aligned at a different angle to the longitudinal axis 20 of the unit body 14. These tool holders 16 are arranged relative to one another in such a way that the longitudinal center axes of the respective machining tools 18 are not parallel and point in different spatial directions.

[0022] The different angles of the tool holders 16 to the longitudinal axis 20 of the unit body 14 can be selected as desired and can be in the range of greater than + / -0° and less than + / -90°, for example at an angle of + / -45°, to the longitudinal axis 20 of the unit body 14. Figure 2 The processing unit 13 shown represents only an exemplary embodiment with seven tool holders 16 and processing tools 18. The processing unit 13 can also have fewer than seven or more than seven tool holders 16, the respective orientation of which can have any angle to the longitudinal axis 20 of the unit body 14.

[0023] A pivoting device 21 is provided on the unit body 14, which enables a pivoting movement of the unit body 14 relative to the connecting device 15. The pivoting movement allows the machining tools 18 to be positioned relative to the workpiece 11. The pivoting device 21 has a pivot axis that can be aligned axially to the central axis of the connecting device 15, axially offset from the central axis of the connecting device 15, or at a different angle to the central axis of the connecting device 15. The pivoting movement, in particular, creates a rotational movement of the machining unit 14 about the Z-axis. In this way, a six-axis actuating movement of the machining unit 14 can be controlled by the actuating device in conjunction with the pivoting device 21.

[0024] A drive can be provided in or on the unit body 14 to control the pivoting movement of the unit body 14. The drive can be pneumatic or electric. The rotational movement can be continuous or provided at defined angles of rotation. The pivoting device 21 and / or the drive can have an interface connected to a controller of the processing device 10 in order to control the actuating movement of the processing unit 13.

[0025] In the following Figures 3 to 10 Various machining processes using the previously described machining unit 13 are shown as examples. The described alignments of the machining unit 13 to the workpiece 11 are achieved by appropriately controlling the adjusting device and / or the swivel device 21.

[0026] Figure 3shows a vertical machining operation with the machining unit 13, wherein a drilling operation is carried out into the workpiece 11 with the three machining tools 18 (drilling tools) aligned axially to the longitudinal axis 20 of the unit body 14. This machining operation allows three drill holes to be drilled vertically into the workpiece 11 simultaneously.

[0027] Figure 4 shows an alternative vertical machining process with the machining unit 13, in which the machining unit 13 is aligned at an angle, for example 45°, to the workpiece 11. The drilling process is carried out by one of the machining tools 18 (drilling tools), which is aligned at a different angle to the longitudinal axis 20 of the unit body 14, for example 45°.

[0028] Figure 5shows another alternative vertical machining process with the machining unit 13, in which the machining unit 13 is aligned parallel to the workpiece 11. The drilling process is carried out by one of the machining tools 18 (drilling tools), which is aligned at a right angle to the longitudinal axis 20 of the unit body 14.

[0029] Figure 6 shows a horizontal machining process with the machining unit 13 in a side view and Figure 7 in a top view, wherein the machining operation is carried out into the workpiece 11 with the three machining tools 18 (drilling tools) arranged axially to the longitudinal axis 20 of the unit body 14. This machining operation allows three drill holes to be drilled horizontally into the workpiece 11 simultaneously.

[0030] Figure 8shows an oblique machining operation with the machining unit 13, in which the machining unit 13 is aligned vertically to the workpiece 11, and the machining operation is carried out by one of the machining tools 18 (drilling tools) that is aligned at a different angle to the longitudinal axis 20 of the unit body 14. In this way, a drill hole can be drilled into the workpiece 11 at this different angle, for example, 45°.

[0031] In the Figures 9 and 10 In addition, a machining tool 18, which is designed as a sawing tool, is provided on one of the tool holders 16. By appropriately aligning the machining unit 14 to the workpiece 11, a sawing or grooving process can be carried out on the workpiece 11 with the sawing tool. Figure 9the processing unit 13 and the sawing tool 18 are aligned vertically to the workpiece 11, so that a vertical longitudinal cut can be made on the workpiece 11. In Figure 10 The processing unit 13 and the sawing tool 18 are arranged at an angle to the workpiece 11, so that the sawing tool 18 can perform an oblique saw cut on the workpiece 11. By appropriately aligning the processing unit 13 to the workpiece 11, any sawing angle can be set.

[0032] It will be apparent to those skilled in the art that individual features described in different embodiments may also be implemented in a single embodiment, provided they are not structurally incompatible. Likewise, various features described in a single embodiment may also be provided in multiple embodiments individually or in any suitable subcombination.
