Description

[0001] The invention relates to a processing station for processing plate- and / or board-like workpieces.

[0002] Linear automatic machining centers are used as processing stations in industries such as furniture manufacturing. These are typically relatively short transfer lines in which the workpiece-carrying transport system is surrounded by several closely spaced processing machines in the central section.

[0003] From DE 10 2013 221 725 A1, a method and a device for machining workpieces are known. The workpieces are moved and supported on horizontally aligned conveyor rollers on the machine bed. The machine bed and the conveyor rollers are bridged by a portal on which the machining unit with its tools is movably arranged.

[0004] EP 2 796 257 A1 discloses a vertical machining center in which the workpiece is moved in the X direction and a machining head in the Y direction. The machining units mounted on the machining head are movable in the Y and Z directions for machining the workpiece. During machining, the workpiece is pressed onto support rollers of a support wall, which can cause damage to the workpiece.

[0005] According to US 4,955,119 A, a stationary workpiece held on a freestanding workpiece stand is machined from the front and the back using a master unit and a slave unit.

[0006] The present invention is based on the problem of developing a processing station in which various tools can be moved freely in three-dimensional space, either individually or in groups, in order to separate and / or join and / or handle plate- and / or board-like workpieces.

[0007] This problem is solved by the features of the main claim. The machining station has an elongated workpiece support gate against which the workpieces rest, allowing for movement on one side. A support device is integrated into the workpiece support gate, which supports and / or fixes the workpieces during machining. The machining station has a transport system for the workpieces, which at least carries, guides, and moves them along the workpiece support gate. It has at least one handling device, which is an automatically controlled, freely programmable, multi-purpose manipulator movable in three or more axes. Each handling device carries and guides a multifunctional unit, which has at least two different tools. For machining the stationary or moving workpiece via the handling device, at least one tool can be brought into engagement with the workpiece.The movable support device is arranged in a recess of a workpiece support frame mounted on a machine bed, with an upstream workpiece transport system and workpiece carriages for plate- and / or board-like workpieces. The workpiece support frame has a support surface for leaning against the workpieces, which is inclined at an angle of between 75 and 90 degrees to a horizontal plane. The support device has at least two support blocks that can be moved transversely to the direction of travel of the workpiece carriages from a position behind the plane of the support surface to a position in the plane of the support surface by means of an external drive.

[0008] The machining station is a universal machine for machining, both with and without machining, e.g., furniture components. The typically large furniture parts are fed to the machine's core area via a dedicated transport system, where they are machined with holes, recesses, countersinks, grooves, notches, chamfers, and the like. Simultaneously, the machine can, for example, insert dowels and handle and mount fittings. The workpieces, i.e., furniture components or their semi-finished products, can also be inspected or measured before and / or after machining, e.g., with regard to their geometry.

[0009] The machining station is designed to process a wide variety of workpieces sequentially without retooling. For this purpose, the plate- and / or board-like workpieces are transported along an elongated, e.g., straight, workpiece support gate to a robot or group of robots. Each robot carries a multifunctional unit. Each multifunctional unit is a carrier for a multitude of driven tools, some of which extend from the machining side of the unit. To machine the workpieces, the robot(s) move their multifunctional units toward the respective workpiece and then swivel them away again after machining. If several robots are operating simultaneously, the tools of multiple multifunctional units machine the workpiece, with the multifunctional units moving independently of each other.The processing station is therefore a robot cell.

[0010] If wear is detected on a single tool during the machining process, the robot swivels the multifunction unit carrying that tool out of the machining zone. There, either an operator replaces the defective tool, or the multifunction unit is automatically replaced with an identically equipped unit. Both the multifunction units and the robots are equipped with adapters for a corresponding quick-change coupling.

[0011] In addition to hold-down devices, pressure stamps, and pressure bars, extendable grippers may also be integrated into the multifunctional unit as joining tools. These grippers can, for example, press wooden dowels into corresponding holes in the workpieces. The multifunctional unit uses the gripper(s) to pick up one or more wooden dowels at special transfer points.

[0012] Further details of the invention will become apparent from the dependent claims and the following description of at least one schematically illustrated embodiment.

[0013] The Fig. Figure 1 shows a machining station for processing plate- and / or board-like workpieces (9). For this purpose, the machining station has, for example, a straight, elongated machine bed (1) on which a workpiece support frame (10) is mounted. A workpiece transport system (2) is arranged along the workpiece support frame (10). The latter consists, among other things, of two, for example, parallel transport rails (3), each ending in front of rotary tables (4, 5). Self-propelled workpiece carriages (6), possibly grouped together, move on the rails (3) located in front of the workpiece support frame (10), transporting the workpieces (9) forward along the workpiece support frame (10). The workpiece carriages (6) return on a transport rail located behind, above, or below the workpiece support frame (10).

[0014] The workpiece support gate (10) serves to position the plate- or board-shaped workpieces, which are made, for example, of materials such as wood, particleboard, plasterboard, fiber cement, or the like. These materials also include composite materials and aluminum alloys.

[0015] Opposite the workpiece support gate (10) and beyond the workpiece (9), for example, two handling devices (7) are arranged, each carrying and guiding a multifunctional unit (8). The handling devices (7) are, for example, articulated robots with so-called RRR kinematics.

[0016] The Fig. Figure 18 shows a handling device (7) designed as a multi-jointed articulated robot (80) with so-called RRR kinematics. The serial kinematic structure of the articulated robot (80) has three main rotational axes and three secondary rotational axes. The main axes are the A-axis (82), the B-axis (84), and the C-axis (86). The A-axis (82) is a rotary table (83) with a vertical axis of rotation, which is mounted on the base plate (81) of the handling device (7). The rotary table (83) supports, as the first link in the kinematic chain, a foot lever (85) that can pivot about the horizontal B-axis (84) – for example, by 210 degrees. At the free end of the foot lever (85), the C-axis (86) is mounted as a joint with a similarly horizontal pivot axis and carries the toggle lever (87). The knee lever (87) can be pivoted relative to the foot lever (85) by, for example, 270 degrees.

[0017] The first secondary axis, the D-axis (88), is a rotational axis. It consists of a support arm (89) rotatable about its longitudinal axis, which is mounted at the free end of the toggle lever (87). The second secondary axis is the E-axis (91), about which the hand lever (92) is pivotally mounted, for example, by 270 degrees. The hand lever (92) carries a rotary table (94) that can be pivoted by 360 degrees and is rotatably mounted about the F-axis (93). The rotary table is the last link in the kinematic chain. The robot flange (121) of the tool interface system (100), which supports the multifunction unit (8), is attached to it (see figure). Fig. 5 and Fig. 6, adapted.

[0018] By appropriately coordinating the control of the individual axes (82, 84, 86, 88, 91, 93), virtually any straight path or curved trajectory within the workspace of the articulated robot (80) can be traversed. This can also be achieved with handling devices (7) based on a Cartesian, cylindrical, or polar robot. These robots then have TTT, RTT, or RRT kinematics, respectively. Here, "T" stands for translational and "R" for rotational main axes or guides.

[0019] Each multifunctional unit (8), carried and guided by the articulated robot (80), has a variety of identical and / or different tools with which holes, recesses, slots, and the like can be machined into the respective workpiece (9). For this purpose, the tools required for a machining step, e.g., a group of four drills, are pneumatically extended from the multifunctional unit (8), locked in place, and set into rotation. With the drills rotating, the multifunctional unit (8) is then positioned in a preselected position in front of the workpiece (9) and from there moved in a straight line against the workpiece (9) by means of the handling device (7) to produce the required row of holes. At the end of the drilling process, the multifunctional unit (8) is retracted. At the same time, the active drills are retracted, and their rotation is switched off.

[0020] The Fig. 2 and Fig. Figure 3 shows an external view of a multifunctional unit. The multifunctional unit (8) has a base body (20) that is essentially in the shape of an elongated cuboid with two long parallel side walls and two considerably smaller end faces. The side walls and end faces enclose a front face, which is a so-called tool-carrying tool side (21). On the rear of the multifunctional unit (8) is an adapter side (22) parallel to the tool side. In the central area of ​​the base body (20), an electric drive motor, e.g., a servo motor, is located under a cover (28). Fig. Figure 3 shows that the left end face has a vertical groove, while the right end face is partially recessed. Valve blocks (41) are arranged in the groove and in the recessed area. The respective depths of the groove and the recessed area correspond to the height of the valve blocks (41).

[0021] The servomotor (30), which may have a cooling system (46-47), is installed in the base body (20) such that its drive shaft (35) points downwards. In the lower part of the base body (20), a main drive gear (32) mounted on the drive shaft (35) of the servomotor (30) meshes with a gearbox consisting of a plurality of spur gears (32-36), cf. Fig. 4 and Fig. 7. The Fig. Figure 4 shows a section through the base body (20) or the gear train, which is aligned parallel to the adapter side (22). The drive gear (32) meshes with three larger distributor gears (33), which are connected via further distributor gears (33) to a larger number of output gears (36). The output gears (36), whose center lines are 32 mm apart in the exemplary embodiment, belong to pneumatically extendable spindles or quills (61).

[0022] In Fig. Figure 7, which shows a cross-section of the multifunctional unit, depicts the drive motor (30) in longitudinal section. The drive motor (30), e.g., a servo motor, has a stator (44) surrounded by a liquid-cooled cooling housing (43). The cooling housing (43) is a tubular cooling jacket (46) whose inner wall seals against the outer wall (45) of the stator (44). The cooling jacket (46) has two circumferential grooves (48) at the front and rear, in which sealing rings (49) are arranged. A helical groove (47) is machined into the cooling jacket (46) between the front and rear sections. In the exemplary embodiment, the groove cross-section has a depth of 6 mm and a width of 12 mm. The inwardly open groove (47) becomes a closed, flow-through channel through the outer wall (45) of the stator (44), thus forming a heat exchanger.A liquid coolant, e.g., a water-glycol mixture, is introduced into one end of the groove (47) via the base body (20) and is then discharged again at the other end of the groove (47) via the base body (20). Sealing agents are arranged around the inlet and outlet points.

[0023] The heat exchanger provides a cooling capacity of approximately 1 kW per drive motor (30). It is typically located in a cooling circuit together with a circulation pump arranged in the base body (20). An active cooling unit may also be integrated into the cooling circuit.

[0024] Each quill (61), see. Fig. 7, ends in the area of ​​the tool side (21) in a spindle carrying a tool holder (62), in order to accommodate, for example, drills or milling cutters as tools. At least some of the spindles have an extension stroke of, for example, 60 mm. The extendable tools are located in their rest position in a recessed parking position (75), cf. Fig. 2. To machine a workpiece (9), they are extended from there to a working position (76) individually or in groups. Regardless of the parking or working position (75, 76), all gears (32 - 36) remain permanently engaged.

[0025] Within the main body, all gears (32-36) are arranged in a single plane. Each gear is located in a cylindrical recess in the main body, which is, for example, 1 to 2 mm larger than the respective pitch circle diameter of the gear (32-36) located therein. This results in a narrow gap (38) around the gears. At the same time, the end faces of the gears have a clearance of only 0.2-0.4 mm on each side from the main body. Several externally accessible lubricant supply points open into the continuous gap (38) within the main body. The gap (38) is partially filled with grease via these points. During operation, the lubricant is continuously conveyed along the gear train by the gears (32-36).

[0026] After the Fig. 2 and Fig. 3. On the tool side (21), along the rear side walls, for example, 16 quills (61) with extendable spindles are arranged. Each spindle carries, for example, a drill (52). The drills alternately rotate clockwise and counterclockwise. In the embodiment according to Fig. In the central area, four drills are grouped together by software. They are shown here, for example, extended. In the area of ​​the opposite side walls, a group of eight quills with clamped twist drills (52) is shown. All twist drills (52) described so far are aligned perpendicular to the tool side (21). A saw disc (58) for producing the recesses for Clamex connectors is shown between the twist drills of the eight-hole group and the rear end face. An extendable single-angle head (63) is arranged between the twist drills of the eight-hole group and the row of 16 quills (61). This head supports a large saw disc (54) whose plane is aligned parallel to the long side walls.Between the cover (28) and the front end face (23), a double-angle head (65) is recessed in the base body (20). This head carries a saw disc (57) on one side and a twist drill on each side. The axes of rotation of the saw disc and the twist drills run parallel to the tool side (21) and to the long side walls (25).

[0027] Between the cover (28) and the front long side wall (25) are two small, parallel double-angle heads (66). Both double-angle heads (66) are in the working position (76). Each double-angle head (66) carries a twist drill on each side, which is also aligned parallel to the tool side (21) and the long side walls (25). At the corner between the front side wall (25) and the front end face (23) are two further double-angle heads (66) arranged one behind the other. These, however, are in the parked position (75).

[0028] Between the double-angle head (65) and the front face (23), a joining tool (70) is recessed into the tool side (21). This tool is a pneumatically extendable pressure ram (71), which, for example during a drilling operation, presses the plate-shaped workpiece (9) against the workpiece support gate (10) or another support device. The pressing action and subsequent release occur without damaging the workpiece (9).

[0029] In Fig. Figure 8 shows several pressure bars (72) in addition to the pressure rams (71). The pressure bars (72), which act as hold-downs, are, for example, long bars that are mounted and guided in the multi-function unit and can be extended and retracted. These pressure bars (72), e.g., rigid, ribbed, and weight-optimized beams, are used as sliding hold-downs. They are used when the workpiece (9) is to be provided with a groove, a notch, or another elongated recess whose longitudinal extent lies in the workpiece transport direction. These recesses are created by drawing the workpiece (9) between the stationary multi-function unit and the stationary workpiece support frame (10) – e.g., with a rotating saw disc (54) – in the workpiece transport direction using the workpiece carriages (6).To prevent the workpiece (9) from lifting off the workpiece support frame (10) during the sawing or milling process, the pressure bars (72), which are arranged here, for example, on both sides of the saw disc (54), are pneumatically extended in the direction of the workpiece support frame (10).

[0030] For this purpose, the pressure strips (72) are oriented parallel to the workpiece transport direction. In the exemplary embodiment, they are also aligned in the direction of the maximum longitudinal extension of the multifunction unit. In order to be able to slide along the workpiece (9) with low friction and without damage, the pressure strips (72) are equipped with a corresponding sliding coating (73), cf. Fig. 7 and Fig. 8. The front pressure bar (72), mounted on the large side wall, is attached to two guide rails (77) that rest perpendicularly against it from below. Each guide rail (77) is guided in at least one ball bearing shoe (78) arranged on the base body (20). Two pneumatic cylinders (79) are arranged on the base body (20) parallel to the guide direction of the ball bearing shoes (78). The piston rods of these cylinders are articulated to the pressure bar (72). The pressure bars (72) are extended in a controlled manner as required. After completion of the sawing or milling operation, they are retracted back into their parked position.

[0031] Independently of the machining and / or joining tools, a 1D or 3D multi-coordinate probe or the like can also be arranged on the base body (20). The probes, which can be extended or folded out from the base body, for example, serve to align the multi-function unit relative to the workpiece support frame or the machine bed. For this purpose, corresponding reference geometry is arranged on the workpiece support frame or the machine bed, which can be approached by the probes to measure the measuring instruments.

[0032] An electronic spirit level and, if necessary, an acceleration sensor are arranged in or on the base body in order to be able to redundantly control the position in three-dimensional space independently of the control data of the controls responsible for the handling devices and the multifunctional units carried by them.

[0033] The Fig. 5 and Fig. Figure 6 shows a tool interface system with a base-side adapter (101), a so-called tool flange, and a mating adapter (121), a so-called robot flange, which is attached, for example, to a handling device (7). The adapter (101) has a flange plate (102) screwed onto the adapter side (22) of the base body.

[0034] A flange ring (104) is integrally formed on the flange plate (102). A centering bore (103) extends through the combination of the flange plate and flange ring. The inner wall of this bore features a locking ring groove (105). Outside the flange ring (104), the flange plate (102) carries two widely spaced centering sleeves. Six frustoconical rotary locking recesses (111) are arranged equidistantly in the free end face of the flange ring (104).

[0035] The complementary counterpart to the adapter (101) is a counter-adapter (121) arranged on the handling device (7). After Fig. 5 has a centering collar (123) on the back of its flange plate (122), by which it is centered on the handling device. On its side facing the adapter (101), compare Fig. 6. A large cylindrical flange pin (124) rises on the flange plate, surrounded in its lower region by a cylindrical centering collar (123). The flange pin (124) has, for example, six movable locking bolts (126) projecting radially around its circumference. The locking bolts (126) can be seen into the flange pin (124), for example, pneumatically. The locking bolts (126) are engaged in the flange pin, for example, by means of air pressure and / or spring force.

[0036] In order to pre-center the tool flange on the robot flange during cranking, two additional centering bolts (127) are arranged on the flange plate (122) - in the area of ​​the outer edge.

[0037] On the free end face of the centering center collar (123), which is recessed relative to the centering bolts, there are, for example, six conical rotary locking pins (131). The rotary locking pins are arranged offset from the centering bolts.

[0038] When the adapter is coupled to the mating adapter, the centering pins (127) are first engaged in the centering bores (107) of the centering sleeves (106), thus pre-centering. Almost simultaneously, the flange pin (124) engages in the centering bore (103). The locking pins (126) then engage in the locking ring groove (105) of the adapter, pulling and locking the multifunction unit against the last element of the respective handling device (7). Additionally, the conical locking pins (131) engage in the locking recesses (111) during coupling. These recesses prevent the adapter from rotating relative to the mating adapter. The locking pins are dimensioned in terms of their number and cross-section to withstand the large load moments occurring around the centerline of the tool interface.

[0039] Each flange (101, 121) has, for example, six external recesses (115, 135) in each of which a transmission module (141-146) can be arranged. Two transmission modules (141, 142; 145, 146) facing each other within the tool interface system (100) form a pluggable transmission module pair. The in Fig. Five front-mounted transmission modules (141, 142) have two adjacent 19-pin connectors on their respective end faces. The tool-side transmission module (142) carries the plugs, while the robot-side transmission module (141) has the corresponding sockets. The two other transmission modules per flange (101, 121) each have six connections for compressed air transmission.

[0040] The adapter (101) has an adapter area opposite the adapter side (22) that is considerably smaller than the total area of ​​the adapter side (22). The size of the adapter area is 20 to 30 percent of the total area of ​​the adapter side (22).

[0041] After Fig. 1 The tool interface system (100) of the right-hand handling device (7) has a spacer flange (137) which is arranged either between the adapter side (22) of the multifunction unit (8) and the adapter (101) or between the last element of the handling device (7) and the mating adapter (121). The spacer flange (137) has a length that is, for example, on the order of the height of the multifunction unit.

[0042] Furthermore, after Fig. 1. Next to each handling device (7) is a unit storage location (15). The multifunctional units are placed on the unit storage locations by the handling devices so that they are freely accessible for maintenance, replacement or tool changes.

[0043] The workpiece transport system (2), see below. Fig. Figure 1 provides, in the exemplary embodiment, a rail system surrounding the workpiece support gate (10) for transporting the workpieces (9), with self-propelled workpiece carriages (6) mounted on or along the rail system. The rail system consists of two parallel transport rails (221, 222), each terminating at its end in front of turntables (4, 5). The self-propelled workpiece carriages (6), which may be grouped together, move on the transport rail (221) located in front of the workpiece support gate (10), transporting the workpieces (9) along the workpiece support gate (10).

[0044] The Fig. Figure 9 shows the front end view of the workpiece transport system (2). It is mounted on the machine bed (1). Transport rails (221, 222) are attached to the front and rear of the machine bed. Each rail consists of a rigid support bracket (223), a support rail (227), and a rack (231). The support rail (227) sits on the support bracket (223), while the rack (231) is attached to the lower part of the support bracket (223). A multi-conductor power and signal rail (235) is mounted on the machine bed below the rack (231). The upper part of the rail is covered by a busbar cover (237). Along the machine bed (1), the support bracket (223), the transport rail (221, 222), the rack (231), and the multi-conductor power and signal rail (235) can be assembled from multiple individual components on each side.

[0045] Naturally, the workpiece trolleys (6) can be operated using onboard energy storage devices. These can be, for example, a battery, a high-capacity capacitor, or a combination of both.

[0046] In addition to or instead of using a battery, the workpiece carriage (6) can be equipped with a receiver, e.g., in the form of a coupling coil, which forms part of a wireless power transmission system. Coupling coils serving as transmitters for a power supply unit are installed in a battery charging area along or parallel to the transport rails (221, 222), e.g., also on a siding or storage track. The workpiece carriage (6) with its receiver is positioned over these coils for a specific charging time. The two closely spaced coupling coils are inductively coupled, with the magnetic flux generated by the transmitter inducing an alternating voltage in the receiver-side coupling coil. The alternating voltage is rectified and fed to a charging controller on the workpiece carriage, which in turn charges the energy storage device.

[0047] In the exemplary embodiment, both transport rails (221) and (222) are of the same length and oriented parallel to each other. Their upper edges also lie in a common horizontal plane. At each end of the machine bed, two transport rail ends (225, 226) terminate at the same height. There, according to Fig. 1 each a turntable (4, 5).

[0048] In Fig. 10 is the next Fig. Figure 1 shows the front turntable (4, 5). It has a support plate (255) at the level of the support brackets (223), which serves as a rotatable tabletop. A turntable support rail (241, 242) is attached to each of two opposite edges of the support plate (255). The two turntable support rails (241, 242) are spaced exactly as close together as the support rails (227) of the straight transport rails (221, 222). Below the support plate (255), the turntable rack, the multi-conductor power and signal rail (245), and the power rail cover (247) are arranged in the same manner as on the straight transport rails (221, 222).

[0049] The support plate (255) rests on a pipe flange (254) on the roller-bearing rotary table (257) of a bearing housing (253). The bearing housing, in turn, is screwed onto the machine bed (1), cf. Fig. 1. The bearing housing contains, for example, a bevel gear that drives the rotary table, which is connected, for example, via an external traction gear (252) to an electrically driven rotary disc motor (251) attached to the bearing housing (253).

[0050] On the underside of the support plate (255), in the area below the turntable support rails (241, 242), there is an angled rack support rail (256) to which the turntable rack (243) is attached. Behind each rack support rail, two rail supports (258) are arranged, projecting downwards. The multi-conductor power and signal rails (245) and the conductor rail covers (247) are attached to each pair of rail supports (258).

[0051] To enable the workpiece carriages (6) to be transferred smoothly from one transport rail (221, 222) to the other transport rail (222, 221), the turntable support rails (241, 242), the turntable racks (243), and the multi-conductor power and signal rails (235) of the transfer unit (240) are also chamfered at their ends such that the free end faces of these components are curved in a cylindrical shape, with the center line to the surface portion of the cylindrical shell being the pivot axis (259) of the turntable (4, 5). The support rails (227), the racks (231), and the multi-conductor power and signal rails (235) of the transport rails (221, 222) have correspondingly concave end faces. The gap between the opposing end faces has a gap width of 0.1–0.3 mm.

[0052] The diameter of the imaginary cylindrical shell on which the end faces of the support rails (241, 242) and the racks (243) lie, whose center line lies on the pivot axis (259), is larger than the shortest distance between the support rails (227).

[0053] To move a workpiece carriage (6), for example, from the rear transport rail (222) to the front transport rail (221), the workpiece carriage (6) moves to Fig. 1. The workpiece carriage (6) moves onto the rear turntable support rail (242). The turntable then rotates 180 degrees around its pivot axis (259). From there, the workpiece carriage (6) moves onto the transport rail (221). Once the workpiece carriage (6) has passed through the machining station and reached the rear end of the transport rail (221), it moves onto the turntable support rail (242) of the rear turntable (240) to be transferred to the rear transport rail (222).

[0054] Accordingly, each workpiece carriage (6) travels in a circle within the workpiece transport system (2). When the angular velocity of the turntable (4, 5) is set to the travel speed of the individual workpiece carriage (6) – i.e., when the peripheral speed of the turntable at the level of the support rail (241, 242) corresponds to the travel speed of the workpiece carriage (6) – the workpiece carriage (6) completes the transport path of the monorail transport system (2) without any noticeable interruption of speed due to the turntables (4, 5).

[0055] The Fig. 11 and Fig. Figure 12 shows a workpiece carriage (6) from the front and the back. The central component of the workpiece carriage (6) is the angled base body (261). A guide carriage (262) is arranged below the overhang of the base body (261). The guide carriage (262) is a ball bearing that engages the support rails (227, 241, 242) in the vertical and lateral directions. Fig. 12. Below the guide carriage (262) is a countershaft (271) which carries the helical gear (273). The countershaft (271), which is mounted in a bearing block (267) with rolling bearings, has a drive gear (272) – shown with dashed lines – which is enclosed on the outside by a gearbox housing (266) formed on the base body (261). Below the gearbox housing (266) is a flange plate (265) to which a drive unit (263) is adapted. The latter is, for example, a downward-projecting servo motor (264) with an optionally integrated gearbox. On the shaft of the servo motor (264) is a spur gear – not shown here – which meshes with the drive gear (272) of the countershaft (271).

[0056] On the underside of the base body (261), next to the drive unit (263), a downward-projecting pickup arm (285), a sheet metal component, is arranged. The current and signal pickups (286) are spring-mounted to this arm. In this case, seven pickups (286) are used. The uppermost one is connected to ground, for example. The next two current pickups (286) carry +48 V and -48 V at, for example, 10 A. The fourth and fifth pickups are each current pickups (286) for +24 V and -24 V at 5 A. The two lower pickups (286) are signal pickups for the CAN bus used, for example, here.

[0057] After Fig. In the 12 embodiment, a so-called lubrication wheel (282) is arranged several millimeters away from the output gear (273). The lubrication wheel (282), which does not mesh with the output gear (273), is mounted on the bearing block (267) via a lubrication wheel axle (281). In the exemplary embodiment, it is a felt wheel that is externally lubricated with lubricating oil at one or more points in the area of ​​the racks (231, 243) by means of a small quantity lubricant lubricator. The felt wheel (282) continuously rolls against the racks (231, 243) and thus distributes lubricant onto the helical racks (231, 243).

[0058] Instead of the felt wheel (282), a sintered or at least partially porous metal, ceramic, or plastic wheel can also be used, which is supplied with pressurized oil via the lubrication wheel axle (281) extending from the base body (261) of the workpiece carriage (6), e.g., at regular intervals. In this variant, the pressurized oil emerges in the central region of the tooth flanks of the lubrication wheel (282) so that it can be transferred to the tooth flanks of the racks as it rolls. The oil pressure of the lubricant tank embedded in the base body (261) can be generated by a small pump driven by the rotation of the lubrication wheel (282).

[0059] According to the Fig. 11 and Fig. 12. A collet chuck (290), which can be actuated electromechanically, is mounted on the base body (261) of the workpiece carriage (6). A slide with two cam recesses is arranged in the chuck housing (291). The slide – not shown here – is moved by an electrically driven cam drive to open and close the collet chuck (290). Each cam recess has a different pitch.

[0060] Above the slide, two carriages (293, 294) are positioned one behind the other in the gripper housing (291), transverse to the guide carriage (262). Each carriage is connected to one of the slide's cam recesses via a pin. Furthermore, each carriage carries a gripping element (295, 296) on its upper surface. The in Fig. 12 front gripping element (296) lies down after Fig. 9 on the rear of the plate-shaped workpiece (9) via only a short stroke. For this purpose, the cam recess located under the slide (294) has only a slight incline. The after Fig. The front gripping element (295), which is attached to the slide (293), has the task not only of gripping a workpiece (9) placed on the workpiece carriage (6), but also of pulling it against the workpiece support gate (10) and the gripping element (296). A large stroke is required for this. Therefore, the cam recess in the slide has a steep pitch.

[0061] The collet (290) has a bearing block (310) below each of the lateral projections of the gripping elements. Each bearing block (310) has, according to Fig. 11 two adjacent rollers (311). These rollers (311), which are mounted in the respective bearing block (310) by means of rolling or sliding bearings, bear the workpiece load.

[0062] After Fig. 9 The weight load of the workpiece (9) is introduced to the right of the center of the guide carriage (262). This creates a torque around the support rail (227) acting in a clockwise direction, which presses the workpiece carriage (6) with its output wheel (273) and its current and signal pickups (286) against the transport rail (221) in a stabilizing manner.

[0063] After Fig. For example, workpiece support gate (10) has a recess (14) in the center, in which a special support device (430) is mounted on the machine bed (1). The recess (14) is located opposite the two handling devices (7).

[0064] The Fig. 13 and Fig. Figure 14 shows the support device (430) from two different directions. The in Fig. The support structure (430) shown in Figure 13 faces forward. The support structure (430) consists of two nested support blocks (450, 470). Each support block (450, 470) is a type of tower, essentially consisting of four larger components. These are, for example, two identical side plates (455, 475), a support plate (451, 471), and a stiffening plate (456, 476). The side plates (455, 475), which are arranged parallel to each other, are held apart by the support plate (451, 471) and the stiffening plate (456, 476). The side cheeks (455, 475) of both support blocks (450, 470) each have front edges that form an angle of, for example, 80 degrees with the respective support plate (451, 471). The workpiece support gate (10) is also inclined at this angle with its support surface (465, 475) to a horizontal plane.

[0065] The rear edges of the side cheeks (455, 475) form an angle of, for example, 72 degrees with a horizontal plane. On each support bracket (450, 470), the respective stiffening plate (456, 476) is located in the upper region of the side cheeks (455, 475), parallel to the rear edges. Each stiffening plate (456, 476) is rectangular with four recesses. The recesses each have a triangular contour, so that two diagonal ribs remain between the four corners of the respective stiffening plate (456, 476).

[0066] Each suction cup side cheek (455) carries on its outer surface a plurality of, for example, identical suction cup carriers (457), each of which has a constant distance from the others. On each of the suction cup carriers (457) arranged one above the other, there is, for example, a suction element (458) which is designed as a vacuum suction cup.

[0067] Longer suction cup carriers (457) are arranged in the area of ​​the lower end of the suction cup side walls (455), each having two suction elements (458) positioned side by side. Using these superimposed suction elements (458), whose suction or contact plane forms an imaginary support surface (465), large, plate-like workpieces (9) are typically suctioned against the suction cup support block (450) to hold the workpieces (9) firmly against the workpiece support frame (10), for example, during drilling or milling, against the tool pull-out forces. The four suction elements (458) located at the bottom are used, for example, to fix narrow, board-like workpieces to the workpiece support frame (10).

[0068] After Fig. In section 15, the suction cup support block (450) is slidably mounted on a base plate (435). The base plate (435), which is rectangular, for example, sits on a substructure (431). The substructure (431) consists of a base plate (433) that is screwed directly onto the machine bed (1), a base table plate (432) on which the base plate (435) is mounted, and several vertically oriented support plates that maintain the two parallel base plates and table plates (433, 432) at a structurally defined distance. The height of the substructure (431) is chosen so that the lowest suction elements (458) of the suction cup support block (450) are located a few millimeters above the workpiece carriages (6) or their clamping jaws.

[0069] Two parallel guide rails (436) are screwed onto the base plate (435) along the long side edges of the base plate (435), cf. Fig. 14. Four guide carriages (452) are mounted on each of the guide rails (436). The guide carriages (452) located on the outside of each guide rail (436) support the suction support plate (451), see Figure 1. Fig. 15.

[0070] The suction cup support plate (451) has, for example, two openings above each guide rail (436) through which guide carriage spacers (473) are attached, resting on the two inner guide carriages (472). The sliding support plate (471) is mounted on these spacers. The sliding side plates (475) are attached laterally to the sliding support plate (471). The outer surfaces of the sliding side plates (475) are, for example, only 27 mm away from the inner surfaces of the suction cup side plates (455). In the so-called zero position of the support brackets (450, 470), as described in Fig. As shown in Figure 15, the trailing edge of the sliding support plate (471) ends, for example, 11 mm behind the suction support plate (451). In this way, the sliding support block (470) is located completely within the installation space of the suction support block (450).

[0071] Alternatively, the support blocks (450, 470) can also be arranged side by side on the machine bed (1). It is also possible to nest both support blocks (450, 470) within each other in such a way that, for example, one slider side plate (475) is arranged in the suction cup support block (450), while the other lies outside the suction cup support block (450).

[0072] The slider support block (470) has a continuous slide rail (478) on each of the front end faces of the slider side cheeks (475), cf. Fig. 14. Both guide rails (478) clamp a support surface (485) with their front contact surfaces. During the machining of the workpieces (9), for example when sawing or milling a horizontal longitudinal groove, the workpiece (9), guided by the workpiece carriages (6), slides along the workpiece support frame (10). In doing so, it slides over the projecting guide rails (478), against which it is pressed due to the machining forces.

[0073] Instead of the continuous slide rails (478), other sliding elements such as sliding cams, sliding blocks, or rollers can also be used. In the latter case, the axes of the rollers are oriented parallel to the leading edges of the slider side plates (475).

[0074] Within the enclosed space of the slider support block (470), a sensor carrier (444) is arranged approximately in the center. The sensor carrier (444) consists of a sensor carrier plate (445) and two carrier plate feet (446) arranged parallel to each other. The sensor carrier plate (445), for example, is rectangular (see figure). Fig. 13 is oriented parallel to the support surface (16). It has a distance of 15 mm from the support surface (16). Its Fig. Fourteen perforated support plate feet (446) are rigidly mounted on the base plate (435). Both support plates (451, 471) have corresponding recesses to prevent the support plate feet (446) from colliding during operation. The sensor carrier (444) serves, for example, to hold various sensors by which the workpieces (9) can be identified, counted, and / or measured for inspection, possibly via barcodes.

[0075] Furthermore, one or more multi-coordinate probes or the like can be arranged on the sensor carrier (444) to measure the zero position of a multifunction unit (8) positioned relative to the sensor carrier plate (445) – during machining breaks – relative to the workpiece support gate (10). Additionally, probe elements such as cylindrical cones or cubes can be mounted on the sensor carrier (444) and approached for measuring purposes by probes extendable from the multifunction unit (8).

[0076] In Fig. Figure 15 shows the adjustment mechanism (500), which allows the suction cup support block (450) and the slider support block (470) to be slidably mounted relative to the base plate (435), in a section in a neutral position. In the neutral position, the support blocks (450, 470) are positioned relative to the workpiece support gate (10) such that their support surfaces (465, 485) are only a few millimeters behind the support surface (16) of the workpiece support gate.

[0077] A downwardly projecting motor flange (441) and an eccentric shaft bearing flange (442) located above it are arranged in a recess on the base plate (435). The drive (490) is located in the downwardly oriented centering of the motor flange (441), cf. Fig. 14, centrally flanged. The drive (490) directly drives an eccentric shaft (501) of the adjustment gear (500) via a torsionally rigid coupling (491). The eccentric shaft (501) is supported in the eccentric shaft bearing flange (442) via its shaft center section (503) in the eccentric shaft bearings (505) and is fixed axially and radially. The eccentric shaft (501) has an eccentric (502, 504) above and below the shaft center section (503).

[0078] In Fig. Figure 16 shows a section of the adjustment mechanism (500) in a position where the suction cup support block (450) is positioned with its support surface (465) in or in front of the support surface (16) of the workpiece support gate (10). The support surface (465) is in front of the support surface (16) when it is offset towards the workpiece (9). The amount of the offset is, for example, between 0.1 mm and 2 mm. Fig. 16 is the eccentric shaft (501), opposite its position from Fig. Figure 15 shows the suction cup eccentric (502) rotated 90 degrees counterclockwise. This shifts its centerline to the left. The suction cup eccentric (502) is coupled to a suction cup drive shaft (514) via a suction cup connecting rod (510). The suction cup drive shaft (514) is attached to the suction cup support plate (451) via a bridge-like suction cup spacer (515).

[0079] The suction connecting rod (510) is, for example, a cuboid-shaped rod with rounded end faces. At both its front and rear ends, the suction connecting rod (510) has a large transverse bore. Both transverse bores are connected to each other via a central slot (511). A clamping screw (512) is located in a threaded bore in the center of the central slot (511). Two suction connecting rod bearings (513) are located in each of the two transverse bores, and their outer rings are clamped by means of the clamping screw (512). Two inner rings of each of the four suction connecting rod bearings (513) are axially fixed on the eccentric (502) and on the suction drive shaft (514). The eccentric (502), the suction connecting rod (510), and the suction drive shaft (514), which is fixed to the suction support plate (451), together form a push-pull drive mechanism.

[0080] In order to adjust the position of the suction drive shaft (514) relative to the suction support plate (451), according to Fig. 16. An adjusting screw (519) is screwed into the suction cup spacer (515) on the left. Its head rests in a groove in the suction cup support plate (451). The suction cup spacer (115) is attached to the suction cup support plate (451) by its fastening screws via elongated holes on the suction cup support plate side.

[0081] The Fig. Figure 17 shows a section of the adjustment mechanism (500) in the position in which the slider support block (470) has moved forward. In this case, the support surface (485) of the slider support block (470) lies in or in front of the support surface (16) of the workpiece support gate (10). Here, the servo motor (490) has the eccentric shaft (501) relative to the one in Fig. The initial position shown in Figure 15 has been rotated by 90 degrees clockwise. The center line of the slider eccentric (504) has moved forward relative to the center line of the shaft center section (503). Fig.17 to the left, shifted. As a result, the sliding connecting rod (520), which is identical in construction to the naturally aspirated connecting rod (510), has pulled the sliding support plate (471) and with it the sliding support bracket (470) forward. In order to couple the sliding support plate (471) with the sliding connecting rod (520), a sliding drive shaft (524) is screwed to it. The sliding drive shaft (524) can also be moved slightly relative to the sliding support plate (471) by means of an adjusting screw (529).
