Next, the operation of the transfer conveying device 3 having such a configuration will be described. Further, the transfer conveyance device 3 controls the operation by a control device (not shown). Therefore, the main body of the operation of the transfer conveyor 3 described below is a control device (not shown).

In the transfer conveyance device 3, for example, when the jaws are brought close to the workpiece or the jaws are moved away from the workpiece, the feed lever 5 is moved in the clamp direction (Y direction). At this time, the clamp unit 7 moves the slide gantry unit 8 in the clamp direction (Y direction). More specifically, when the clamp motor 7a of the clamp unit 7 is driven and the shaft 7a1 is rotationally driven, the rotary power is transmitted to the ball screws 7c on both sides through the gear case 7b. In this way, the screw shaft 7c1 of the ball screw 7c is rotated, and the nut 7c2 is moved in the clamp direction (Y direction). Here, the winding directions of the screw grooves formed in the screw shafts 7c1 disposed on both sides of the gear case 7b are opposite to each other, so that the nuts 7c2 screwed to the respective screw shafts 7c1 move in opposite directions to each other. . As a result, the slide gantry unit 8 fixed to the nut 7c2 moves in the opposite direction. For example, when the slide gantry unit 8a disposed on the left side of the clamp motor 7a is moved toward the clamp motor 7a, the slide gantry unit 8b disposed on the right side of the clamp motor 7a also approaches the clamp motor 7a. Move in the direction. Further, when the slide gantry unit 8a disposed on the left side of the clamp motor 7a is moved away from the clamp motor 7a, the slide gantry unit 8b disposed on the right side of the clamp motor 7a is also moved from the clamp motor 7a toward Move away from it. In this way, the sliding gantry unit 8 is made Moving in the clamp direction, the feed lever 5 connected to the slide gantry unit 8 is moved in the clamp direction (Y direction).

Further, in the transfer conveyance device 3, for example, when the workpiece is raised or lowered, the feed lever 5 is moved in the lifting direction (Z direction). At this time, the lifting unit 12 moves the sub-skid gantry 11 in the lifting direction (Z direction) with respect to the main sliding gantry 10. More specifically, when the lift motor 12a is driven and the shaft center 12a1 is rotationally driven, the rotary power is transmitted to the ball screw 12b. In this way, the screw shaft 12b1 of the ball screw 12b is rotated, and the nut 12b2 is moved in the lifting direction (Z direction). In this manner, the sub-sliding gantry 11 is moved in the lifting direction (Z direction) with respect to the main sliding gantry 10, so that the feeding lever 5 connected to the sub-skid gantry 11 is moved in the lifting direction (Z direction). Further, when the feed lever 5 is moved in the lifting direction (Z direction), the lever of the cylinder 14 is engaged with the lifting and lowering of the sub-slide gantry 11 to expand and contract, and the sub-slide gantry 11 is constantly supported by the cylinder 14. And the weight of the feed rod 5 supported by the sub-slide gantry 11.

Further, in the transfer conveyance device 3, for example, when the workpiece is moved in the feed direction (X direction), the feed lever 5 is moved in the feed direction (X direction). At this time, the feeding unit 13 moves the feeding lever 5 in the feeding direction (X direction). More specifically, when the feed motor 13a is driven and the shaft center 13a1 is rotationally driven, the rotational power is transmitted to the pinion gear 13b and the pinion gear 13b is rotated. When the pinion gear 13b rotates, the rack 22 that is engaged with the pinion gear 13b is moved in the feed direction (X direction), and the feed lever 5 is moved in the feed direction (X direction).

Thus, the transfer conveying device 3 by transferring the unit 4 The clamp unit 7, the lift unit 12, and the feed unit 13 are driven to move the feed lever 5 in the clamp direction (Y direction), the lift direction (Z direction), and the feed direction (X direction). Then, by combining the above-described three-direction movements, the feed lever 5 moves in three dimensions and moves the material to be processed.

Further, when the slide gantry unit 8 moves beyond the range of the normal movement (the range within the assumption) with respect to the main frame 6, and moves to the abnormal range (the range outside the assumption), the slip can be detected by the overrunning device 7e. The movement of the gantry unit 8 and the movement of the sliding gantry unit 8 are restricted. Further, when the sub-slide gantry 11 moves beyond the general range of movement with respect to the main slide gantry 10 and moves to an abnormal range, the movement of the sub-slide gantry 11 can be detected by the over-limit moving device 12c, and the sub-restriction is restricted. The movement of the sliding gantry 11. Further, when the feed lever 5 exceeds the general range of movement with respect to the sub-slide gantry 11 and moves to an abnormal range, the movement of the feed lever 5 can be detected by the over-limit stopper 23, and the feed is restricted. The movement of the rod 5.

Next, the effect of the transfer conveyance device 3 will be described. According to the transfer conveyance device 3, the transfer conveyance device 3 is provided as the transfer unit 4 such that the clamp unit 7, the elevation unit 12, and the feed unit 13 are integrated. Therefore, with the transfer unit 4, the feed lever 5 can be moved in the feed direction (X direction), the clamp direction (Y direction), and the lift direction (Z direction) in three directions, and the feed lever can be made in three dimensions. 5 move.

Furthermore, in the transfer unit 4, the main slide stage 10 is supported by the main frame 6 in such a manner as to be movable in the direction of the clamp, and the sub slide table The frame 11 is supported by the main sliding stage 10 so as to be movable in the lifting direction (Z direction). Further, the clamp unit 7 that moves the main slide gantry 10 together with the sub slide gantry 11 and the feed lever 5 in the clamp direction (Y direction) is mounted on the main frame 6. Further, the elevating unit 12 that moves the main slide gantry 10 together with the feed lever 5 in the lifting direction (Z direction) is mounted on the main slide gantry 10. Further, the feeding unit 13 that moves the feed lever 5 in the feeding direction (X direction) is mounted on the main slide gantry 10. In the transfer unit 4 having such a configuration, the main slide gantry 10 and the clamp unit 7 are directly mounted on the main frame 6, and the sub slide gantry 11 is mounted on the main frame 6 through the main slide gantry 10, and is transmitted through The main slide gantry 10 mounts the sub slide gantry 11 on the main frame 6, and the elevation unit 12 is mounted on the main frame 6 through the main slide gantry 10, and is fed through the sub slide gantry 11 and the main slide gantry 10. The unit 13 is mounted on the main frame 6. In summary, the clamp unit 7, the lifting unit 12, the feeding unit 13, the main sliding gantry 10, and the sub-sliding gantry 11 are concentrated on the main frame 6. In this way, the feed bar 5 can be moved in three dimensions. As described above, according to the transfer conveyance device 3, all the means for moving the feed lever 5 are concentrated on the main frame 6, and the transfer unit 4 can be miniaturized.

Therefore, according to the transfer conveyance device 3, it is possible to move the feed lever 5 in a three-dimensional manner only by the transfer unit 4 without separately providing a mechanism for moving the feed lever 5 in addition to the transfer unit 4. Therefore, it is not necessary to provide a feeding mechanism and a holder for placing the feeding mechanism as in the conventional conveying apparatus, and the size of the apparatus for moving the feeding rod 5 in a three-dimensional manner can be reduced. Further, a device scale of the transfer press device 1 that transfers the material to be processed using the transfer conveyance device 3 Inch is miniaturized.

Further, in the transfer conveyance device 3, two transfer units 4 are connected to the feed lever 5. Therefore, the feed lever 5 can be stably supported. Further, in a transfer press device having a plurality of slide rails, there is a case where a long feed lever is required. However, by providing three or more transfer units and supporting the feed rods in a plurality of places, the bending of the feed rod can be suppressed.

Further, the transfer conveyance device 3 includes an air cylinder 14 that is mounted on the main slide gantry 10 and hangs the support sub-slide gantry 11 , and a gas tank 15 that is mounted on the main slide gantry 10 and stored and supplied thereto. Compressed air of the cylinder 14. As described above, by mounting the gas cylinder 15 and the cylinder 14 in the same main sliding gantry 10, the gas tank 15 and the cylinder 14 can be disposed in the vicinity, and the piping between the gas tank 15 and the cylinder 14 can be shortened. For example, it is also conceivable to dispose the large-capacity gas tank outside the slide gantry unit 8 without providing the gas tank 15, and supply compressed air from the large-capacity gas tank to the cylinder 14. However, in this case, the distance from the gas tank to the cylinder 14 becomes long, and the pipe connecting the large diameter of the gas tank and the cylinder 14 becomes long.

Further, when the large-capacity gas tank is installed outside the slide gantry unit 8 as described above, the movement of the slide gantry unit 8 causes the pipe connecting the large diameter of the gas cylinder and the cylinder 14 to swing. Therefore, it is necessary to make such a pipe flexible. Further, it is also necessary to arrange such a pipe so that the movement of the slide gantry unit 8 is not hindered. In the transfer conveyance device 3, since the gas tank 15 is mounted on the slide gantry unit 8, the large-diameter pipe is not shaken by the movement of the slide gantry unit 8, and the pipe can be shortened, so that the complexity of the device can be prevented.
