Description

Technical Field

[0001] The invention relates to a machining unit having at least one workpiece track, which has a workpiece supply area of ​​a workpiece supply device and a workpiece table of a machine tool, wherein the machine tool has at least two machining robots and wherein the workpiece table comprises at least one block-shaped suction nozzle group. Background Art

[0002] A machining unit is known from DE 10 2017 104 246 A1, in which workpiece machining is performed with the aid of two machining robots during one workpiece clamping. Summary of the invention

[0003] The technical problem to be solved by the present invention is to increase the productivity of a processing unit and to expand its processing possibilities.

[0004] The technical problem is solved by means of the features of the independent claim. To this end, the machining unit has a second workpiece track extending in the longitudinal direction of the machining unit and parallel to the first workpiece track, which has a second workpiece table including at least one block nozzle group. In addition, each block nozzle group can be moved in the longitudinal direction of the machining unit.

[0005] The processing unit enables the processing of a large number of workpieces with different geometric structures and different arrangements of processing areas and workpiece cuts. The arrangement of the block nozzle group with respect to the longitudinal direction of the processing unit for the workpiece makes it possible to avoid damage to the block nozzle group during the processing of the cut workpiece. In addition, the provision of the next workpiece and its transportation to the workpiece table can already take place during the processing of the first workpiece. As a result, a high utilization rate of the processing unit can also be achieved in mass production.

[0006] Further details of the invention emerge from the dependent claims and from the following description of the exemplary embodiments shown by way of example. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figures 1 to 7 A machining unit (10) and some components of the machining unit (10) are shown. The machining unit (10) comprises a workpiece supply device (21) and a machine tool (61) connected to the workpiece supply device (21). In the workpiece supply device (21), a workpiece (1; 2) is oriented, for example, by means of a manipulation device or manually loaded, and is taken over by a conveying device (111) of the machining unit (10). The workpiece (1; 2) is then conveyed from the workpiece supply device (21) to the machine tool (61) by means of the conveying device (111) and after machining is conveyed to a workpiece extraction station. In this embodiment, the workpiece extraction is carried out in the workpiece supply device (21) after machining. However, it is also conceivable to arrange the corresponding workpiece extraction station spatially separated from the workpiece supply device (21). The transport of the workpiece (1; 2) from the workpiece supply device (21) to the machine tool (61) is carried out in a first conveying direction (112). For removal, the workpiece (1; 2) is transported in the illustrated embodiment along a second transport direction (113) that is opposite to the first transport direction (112). The transport directions (112, 113) are oriented along the longitudinal direction (5) of the machining unit (10). It is also conceivable that the machined workpiece (1; 2) is transported further along the transport direction (112). For example, the workpiece removal station or a further machining station of the chain production is then located on the side of the machine tool (61) facing away from the workpiece supply device (21).

[0015] The machining unit (10) has two workpiece rails (11, 12) oriented side by side and parallel to each other in a longitudinal direction (5). In a workpiece supply device (21), each of these workpiece rails (11; 12) has a workpiece supply area (22; 23). In addition, each workpiece rail (11; 12) has a working area (62; 63) and a workpiece table (65; 165) in the machine tool (61). The respective working area (62; 63) is a spatial area in which the respective workpiece (1; 2) cooperates with the tool unit (92; 102) of the respective machining.

[0016] See also Figure 2In this embodiment, the workpiece supply device (21) includes a bed (24) which carries two supporting roller rails (25, 26) arranged side by side, a traverse device (41) and two stop devices (52, 53) which are seated, for example, on a common stop strip (51). The bed (24) has an external workpiece trolley guide rail (28) and a conductor rail (29). The workpiece trolley guide rail (28) and the conductor rail (29) extend on a machine bed (64) of a machine tool (61). Along the workpiece trolley guide rail (28), a workpiece trolley (114-117) of a conveying device (111) can travel. In this embodiment, the conveying device (111) includes two workpiece trolleys (114, 115; 116, 117) per workpiece rail (11; 12). The energy supply and control of the self-propelled workpiece trolleys (114-117) are carried out by means of the conductor rail (29).

[0017] Each support roller track (25; 26) comprises a plurality of support rollers (27) which are transverse to the conveying direction (112) and parallel to one another. They can be rigidly designed or can be arranged, for example, in a rolling bearing arrangement on a rigid shaft. In this embodiment, all support rollers (27) are designed to be identical to one another. The width of each support roller (27) is usually greater than or equal to the maximum width of the workpiece (1; 2) to be processed in the transverse direction (6). The support rollers (27) extend in the height direction (7) beyond support roller carriers (31) which are oriented laterally in the longitudinal direction (5).

[0018] exist Figure 3, a transverse device (41) is shown. In this embodiment, it has a rake (42) that can be moved in a transverse direction (6). The transverse device (41) has two transverse guides (32) anchored in the bed (24), each of which carries a transverse slide (43) that can be moved relative to it. The stroke of the transverse slide (43) in the transverse direction (6) is, for example, 40% greater than the width of the support roller track (25; 26) in this direction. The two transverse slides (43) are driven, for example, synchronously with each other. A lifting device (44) is placed on each transverse slide (43), which acts on a tooth carrier (45) oriented in the longitudinal direction (5) and can be adjusted in height of the rake (42). The two lifting devices (44), which are hydraulically operated, are coupled here so that the tooth carrier (45) is always horizontal. The teeth (46) protrude upward from the tooth carrier (45). The teeth (46) are cylindrical bolts in this embodiment. After the rake (42) has been mounted and raised, the teeth (46) are located, for example, between two supporting rollers (27) of the supporting roller track (25; 26). The lifting device (44) is designed so that when the teeth (46) are moved out, they extend 70% of the stroke relative to the supporting plane of the supporting roller track (25; 26). After the lifting device (44) has been lowered, the teeth (46) sink below the supporting plane of the supporting roller track (25; 26). The supporting plane of the supporting roller track (25; 26) tangential to the upper side of the supporting roller track (25; 26) is also referred to as the conveying plane of the processing unit (10) hereinafter. Instead of the rake (42), the traverse device (41) can also have a pivot lever, a sliding key or the like.

[0019] Figure 4 A stop bar (51) is shown. It is oriented in the transverse direction (6) and is arranged at the end of the workpiece supply device (21) facing the machine tool (61). The stop bar (51) has a bolt carrier (54) which carries two stop devices (52, 53) each having two stop bolts (55; 56). Each stop bolt (55; 56) can be adjusted between an inward and outward position by means of a double-acting cylinder (57). In the outward position shown, the stop bolts (55, 56) extend out of the conveying plane by a height of 85% of their vertical stroke. In the inward position, the stop bolts (55, 56) are located below the conveying plane. The stroke adjustment of the hydraulic cylinder (57) is carried out, for example, in groups for each stop device (52; 53).

[0020] exist Figure 51 and 12. The machining unit (10) shown in the exemplary embodiment has four similar workpiece carts (114-117). Two of these workpiece carts (114, 115) are guided along the right side of the machining unit (10) as viewed in the conveying direction (112), and the other two workpiece carts (116, 117) are guided along the left side. A greater or lesser number of workpiece carts (114-117) than shown can also be used. For example, a single workpiece cart (114; 115; 116; 117) can be used for each workpiece track (11; 12).

[0021] Each workpiece carriage (114; 115; 116; 117) has a guide unit (121), a drive unit (125) and a clamping unit (131). The units (121, 125, 131) are integrated in a housing (118). A docking clutch (141) is arranged on the outer side of the housing (118) in this embodiment.

[0022] The guide unit (121) comprises a ball circulation sleeve (122) which, when the workpiece cart (114; 115; 116; 117) is installed, surrounds a workpiece cart guide rail (28) of a workpiece supply device (21) and / or a workpiece cart guide rail (67) of a machine tool (61). The workpiece cart guide rails (28, 67) are fixed to a bed (24) of the workpiece supply device (21) or to a machine bed (64) of the machine tool (61) in a oriented manner in a longitudinal direction (5).

[0023] The drive unit (125) has an energy and signal supply (126). When the workpiece carriage (114; 115; 116; 117) is installed, it rests on a conductor rail (29) of a bed (24) or a machine bed (64) in a spring-loaded manner. A drive motor arranged in the workpiece carriage (114; 115; 116; 117) drives a drive wheel (127), which, when the workpiece carriage (114; 115; 116; 117) is installed, meshes with a rack (33) laterally fixed to the bed (24) or the machine bed (64).

[0024] The clamping unit (131) is arranged above the guide unit (121). It comprises a parallel clamping device (132) having two clamping jaws (133, 134) that can be moved relative to each other. In this embodiment, the two clamping jaws (133, 134) can be moved relative to a housing (118) of a workpiece vehicle (114; 115; 116; 117). The opening and closing directions of the parallel clamping device (132) are oriented in the height direction (7). It is also conceivable to adjust the height of the entire clamping unit (131) relative to the guide unit (121). Here, the two clamping jaws (133, 134) can also be driven separately to be adjusted in height.

[0025] The clamping unit (131) can also be designed asymmetrically. Thus, for example, the lower clamping jaw (134) can have a smaller stroke than the upper clamping jaw (133).

[0026] The docking clutch (141) has, for example, a removable tappet (142) and a plug (143). The plug (143) can be used to transmit electrical energy, data and / or media, such as compressed air for pneumatic functions. In this embodiment, a block suction nozzle group (71; 171) of a machine tool (61) can be coupled to the docking clutch (141). The individual workpiece carriages (114; 115; 116; 117) can also be constructed without a docking clutch (141).

[0027] Figure 6 A machine tool (61) of a processing unit (10) is shown without a processing robot (91, 101). Two workpiece tables (65, 165) are arranged side by side in a machine bed (64). Each of the workpiece tables (65; 165) corresponds to one of the workpiece rails (11; 12). The separation seam of the two workpiece tables (65, 165) extends in a vertical middle longitudinal plane of the machine bed (64). Each of the workpiece tables (65; 165) includes at least one block suction nozzle group (71; 171). In this embodiment, each workpiece table (65; 165) includes a plurality of block suction nozzle groups (71; 171). Each block suction nozzle group (71; 171) can be guided in the machine bed (64) in a movable manner in a longitudinal direction (5). For this purpose, the machine bed (64) has a block suction nozzle guide rail (66) oriented in the longitudinal direction (5). In addition, a chip removal device can be arranged in the machine bed (64).

[0028] exist Figure 7 A block suction nozzle group (71; 171) is shown in the figure. All block suction nozzle groups (71; 171) are constructed as similar, for example. Here, the block suction nozzle group (71) of the first workpiece track (11) is constructed in a mirror-symmetrical manner with the block suction nozzle group (171) of the second workpiece track (12). Each block suction nozzle group (71; 171) has a support rod (72) with two guide groups (73) for guiding along the machine bed (64). Each guide group (73) has two guide sleeves (74) spaced apart from each other in the longitudinal direction (5), between which a clamping device (75) that can be loosened hydraulically or pneumatically is placed. The clamping device (75), which is closed, for example, by spring loading, fixes the position of the block suction nozzle group (71; 171) relative to the machine bed (64) in the longitudinal direction (5).

[0029] The support rod (72) is oriented in the transverse direction (6). It carries, for example, three suction elements (76) placed side by side. These suction elements have a nearly rectangular suction surface (77) with four suction cups (78). The suction elements (76) are designed to be adjustable in height in this embodiment. However, they can also be rigidly designed. Each suction element (76) and / or each suction cup (78) can be operated with negative pressure.

[0030] A support device (81) is arranged on the support rod (72). The support device (81) has a lifting device (82) with a central lifting cylinder (83) and two guide cylinders (84). The lifting device (82) carries a transversely arranged support roller (85). The support roller (85) is rotatably supported, for example, in a U-shaped support carrier (86). A rigid arrangement of the individual support rollers (85) is also conceivable. The lifting device (82) is designed so that a support plane parallel to the conveying plane and tangential to the upper envelope of the support roller (85) can be adjusted from a preparation position below the suction surface (77) to a support position above the suction surface (77).

[0031] A support rod clutch (79) is arranged on the end face of the support rod (72), which is designed to be complementary to a docking clutch (141) of a workpiece carriage (114-117), for example.

[0032] A processing robot (91; 101) is arranged on each side of the machine tool (61). Each of these processing robots (91; 101) carries a tool unit (92; 102). The processing robot (91) located on the right side along the conveying direction (112) is located on the left side. Figure 1 In the illustration of the machine tool (61), a drilling and milling device (92) is carried as a tool unit (92). The tool (94) of the drilling and milling device (92) is, for example, a drilling tool (94). The processing robot (101) located on the left in the conveying direction (112) is equipped with a glue application device (102) for joining a coating of a workpiece, for example, in this embodiment. It is also conceivable to use more than two processing robots (91; 101) in the machine tool (61).

[0033] Each of the processing robots (91; 101) shown can process workpieces (1, 2) on two workpiece paths (11, 12). For this purpose, each processing robot (91; 101) can have a multi-telescopic arm. It is also conceivable that each processing robot (91; 101) can be moved relative to the machine bed (64) in the longitudinal direction (5) and / or in the transverse direction (6).

[0034] In this embodiment, each processing robot (91; 101) has at least one vertical pivot axis oriented in the height direction (7) and at least one horizontal pivot axis oriented parallel to the workpiece table (65; 165). In addition, the corresponding tool unit (92; 102) has a multi-axis swivel head (93; 103). Other configurations of the Cartesian axis box and / or the pivot axis of the processing robot (91; 101) are also conceivable.

[0035] Furthermore, an edge glue applicator (104) is arranged on the machine tool (61), by means of which the edges of the workpiece (1; 2) can be coated.

[0036] In a processing unit (10), for example, no workpieces (1; 2) are initially provided in a workpiece supply device (21). At least two workpiece carts (114, 115; 116, 117) are located on one side in the area of ​​the workpiece supply device (21). The clamping units (131) of these workpiece carts (114, 115; 116, 117) are open. The rake (42) of the transverse device (41) is lowered. The first workpiece (1; 2) is placed in the workpiece supply device (21), for example, by means of a factory conveyor. The first workpiece (1; 2) is, for example, plate-shaped. It is made, for example, of wood, plastic, aluminum, steel, composite material, etc. The placed workpiece (1; 2) is, for example, only roughly oriented when placed. For example, the longitudinal direction of the workpiece can deviate by 30 degrees from the longitudinal direction (5) of the processing unit (10).

[0037] After the first workpiece (1; 2) has been placed, the rake (42) is moved in the transverse direction (6) to such an extent that it is located on the side of the workpiece (1; 2) facing away from the workpiece carriage (114, 115; 116, 117). Subsequently, the lifting device (44) raises the tooth carrier (45) and the tooth (46) until the tooth (46) projects out of the transport plane. The rake (42) can now move the first workpiece (1; 2) in the direction of the clamping unit (131) of the workpiece carriage (114, 115; 116, 117) until the workpiece (1; 2) is located between the clamping jaws (133, 134). In this case, the workpiece (1; 2) is oriented such that the longitudinal side (3) of the workpiece accommodated in the clamping unit (131) is oriented in the longitudinal direction (5) of the machining unit (10).

[0038] Manual delivery and / or orientation of the workpiece (1; 2) is also conceivable. Here, the workpiece (1; 2) placed on the support rollers (27) is pushed by the operator to the workpiece carriage (114, 115; 116, 117) of the workpiece track (11; 12) for processing.

[0039] After the clamping unit (131) is closed, the workpiece trolley (114, 115; 116, 117) pulls the workpiece (1; 2) along the support rollers (27) in the conveying direction (112) until the workpiece (1; 2) abuts against at least one stop bolt (55; 56) of the workpiece rail (11; 12). It is also conceivable that when the clamping unit (131) is closed, the workpiece (1; 2) is lifted a small distance, for example less than five millimeters, from the support roller rail (25; 26). For example, it is then parallel to the conveying plane. The position of the workpiece (1; 2) relative to the workpiece trolley (114, 115; 116, 117) is known from the workpiece position at the stop device (52; 53) and the position of the workpiece trolley (114, 115; 116, 117) relative to the bed (24) in the longitudinal direction (5).

[0040] In a machine tool (61), the position of a block suction nozzle group (71; 171) along a longitudinal direction (5) is adjusted, for example, by means of a spare workpiece cart (114, 115; 116, 117) or by means of an adjustment cart. When an adjustment cart is used, it is constructed, for example, like a workpiece cart (114-117), but does not have a clamping unit (131). In order to adjust each block suction nozzle group (71; 171), the workpiece cart (114; 115; 116; 117) is coupled to the block suction nozzle group (71; 171) by means of a docking clutch (141). The clamping of the block suction nozzle group (71; 171) on the block suction nozzle guide rail (66) is released, and the workpiece cart (114; 115; 116; 117) moves the block suction nozzle group (71; 171) to the desired position relative to the workpiece. Furthermore, the suction element (76) located in the area of ​​the workpiece (1; 2) to be processed is lowered. Thus, for example, damage to the block suction nozzle group (71; 171) is prevented during cutting processing of the workpiece (1; 2). Subsequently, the workpiece trolley (114; 115; 116; 117) is decoupled from the block suction nozzle group (71; 171) and the clamping device (75) of the block suction nozzle group (71; 171) on the machine bed (64) is activated.

[0041] The block suction nozzle groups (71; 171) can also be adjusted with the help of workpiece carts (114, 115; 116, 117) that transport the workpieces (1; 2). For this purpose, for example, after the workpiece (1; 2) has been placed on the support rollers (85), the clamping unit (131) of one workpiece cart (114; 115; 116; 117) is opened, while at least one other workpiece cart (115; 114; 117; 116) holds the workpiece (1; 2). Now, one or more of the block suction nozzle groups (71; 171) can be adjusted with the help of the free workpiece cart (114; 115; 116; 117). After the workpiece (1; 2) has been re-clamped with the help of this workpiece cart (114; 115; 116; 117), another workpiece cart (115; 114; 117; 116) can be used to adjust another block suction nozzle group (71; 171).

[0042] The block nozzle groups (71; 171) can also be moved individually relative to the machine bed (64). For this purpose, for example, each block nozzle group (71; 171) has a drive unit, which rolls, for example, on a rack on the side of the machine bed. In this design, the docking clutch (141) of the workpiece carriage (114; 115; 116; 117) and the support rod clutch (79) of the block nozzle group (71; 171) can be omitted. For example, the adjustment of the block nozzle group (71; 171) along the longitudinal direction (5) is carried out during the workpiece to be processed (1; 2) in the oriented workpiece providing device (21).

[0043] After the stop bolt (55; 56) of the first workpiece rail (11; 12) has been lowered, the workpiece carriage (114, 115; 116, 117) moves the first workpiece (1; 2) further in the conveying direction (112) toward the machine tool (61). The workpiece carriage (114, 115; 116, 117) stops so that the workpiece (1; 2) is located on the support roller (85) at a predetermined position in the corresponding working area (62; 63) of the machine tool (61). Subsequently, for example, a predetermined suction element (76) is raised and / or the support roller (85) is lowered until the workpiece (1; 2) is placed on the predetermined suction element (76). The support roller (85) is lowered further until it is located below the working area (62; 63) of the tool unit (91; 101).

[0044] It is also conceivable that after the workpiece carriage (114, 115; 116, 117) has been positioned, the support roller (85) is raised so that after the clamping element (131) has been opened, the corresponding workpiece (1; 2) is placed on the support roller (85). Subsequently, the support roller (85) is lowered by means of the support roller lifting device (82) until it is located below the support surface. Here, the workpiece (1; 2) is placed on the suction element (76). Here, for example, a height-adjustable clamping unit (131) can continue to hold the workpiece (1; 2).

[0045] A first workpiece (1; 2) is fixed in a processing position by means of a vacuum pump acting on a suction cup (78) covered by the workpiece (1; 2) and resting on the workpiece (1; 2). In this case, for example, the lifting device of the clamping unit (131) is lowered by means of an increased negative pressure. After the workpiece (1; 2) has been fixed by means of the suction element (76), the clamping unit (131) can be released from the workpiece (1; 2) if necessary. The workpiece (1; 2) can now be processed by means of a tool unit (92, 102) and an edge glue applicator (104). In this case, for example, all tool units (92; 102) and edge glue applicators (104) arranged on the processing robot (91, 101) can be used to process the workpiece (1; 2). For example, it is conceivable to completely process the workpiece (1; 2) in one clamping.

[0046] During the processing of the first workpiece (1; 2), the second workpiece (2; 1) can be provided. For this purpose, a workpiece carriage (116, 117; 114, 115) of the second workpiece track (12; 11) is used. The provision of the second workpiece (2; 1) is carried out as described above in conjunction with the first workpiece (1; 2). The second workpiece (2; 1) can already be moved into the working area (63; 62) during the processing of the first workpiece (1; 2). Other workpiece (1; 2) provision and processing sequences are also conceivable.

[0047] After machining the first workpiece (1; 2), the vacuum pump is switched off, for example, and the pressure on the suction surface (77) is raised to ambient pressure. The clamping element (131) clamps the workpiece (1; 2) or continues to hold the clamped workpiece (1; 2). The support roller (85) is raised and / or the suction element (76) is lowered until the support surface is above the suction element (76). The workpiece carriage (114, 115; 116, 117) moves the machined workpiece (1; 2), for example, in the second conveying direction (113) for workpiece removal, which in the present embodiment takes place in the workpiece supply area (22; 23). It is also conceivable to convey the machined workpiece (1; 2) further in the first conveying direction (112), for example to another machining unit.

[0048] When arranging the machining units (10) in chain production, it can be taken into account that the clamping unit (131) remains on the workpiece (1; 2) during the entire machining process. This makes it possible to avoid repositioning the workpiece in the next machining unit (10).

[0049] The first workpiece (1) and the second workpiece (2) can also be processed in parallel with each other. For example, in the same process, the processing robots (91, 101) can have tool units (92, 92; 102, 102) with the same structure. In this embodiment, two workpieces (1, 2) located on workpiece tracks (11, 12) adjacent to each other can be processed in different processes in time parallel with each other.

[0050] The workpiece (1; 2) to be processed can also be wider than a single workpiece path (11; 12). For example, it can then extend into another workpiece path (12; 11). The processing of such a workpiece (1; 2) is carried out as described above. In this case, the following workpiece (2; 1) is not moved into the working area (62; 63) until the preceding workpiece (1; 2) has left both working areas (62; 63).
