  A pallet lifter 67 is provided below the standby shelf 21 in the shelf body 3 so as to freely move up and down to support the processing pallet 7 loaded into and unloaded from the plate material processing machine in two stages. As the pallet lifter 67, the two-stage lifter described in Patent Document 1 can be adopted. However, the two-stage lifter is configured to carry the pallet in and out in one direction. Therefore, the arrangement position of the plate material processing machine is limited to one in the carrying-in / out direction of the pallet, and the degree of freedom of arrangement of the plate material processing machine becomes small.

  Therefore, the pallet lifter 67 according to the present embodiment is configured such that the pallet can be carried in and out in both the X and Y axis directions. That is, the pallet lifter 67 is configured as shown in FIGS.

  More specifically, the pallet lifter 67 operates a link 79 by an appropriate actuator 77 such as an air cylinder, and a pallet support frame 75 in which square portions of a rectangular upper frame 69 and a lower frame 71 are connected by a column 73. Is configured to move up and down. Then, the endless chain 82 for carrying in and out of the pallet is hung around the sprocket 81 rotatably provided at the left and right end portions (X-axis direction) of the upper frame 69 and the lower frame 71. Accordingly, the pallets are individually moved in the X-axis direction with respect to the upper and lower frames 69 and 71 in the pallet support frame 75 by individually rotating and driving each motor (not shown) provided in conjunction with the upper and lower sprockets 81.

An endless chain 91 for loading and unloading the pallet in the Y-axis direction is hung on a sprocket 89 that is rotatably provided near the end in the Y-axis direction of each lifting frame 83.

  Therefore, when the elevating frame 83 is in the lowered state, the pallet can be carried in and out of the upper and lower frames 69 and 71 in the pallet support frame 75 in the X axis direction (left and right direction). In the state where the lift frame 83 is raised, the pallet is supported by the lift frame 83. Therefore, by rotating the sprocket 89 forward and backward via a motor (not shown), the pallet support frame 75 The pallets on the upper and lower frames 69 and 71 can be carried in and out in the Y-axis direction (front-rear direction).

  As already understood, by moving the pallet support frame 75 in the pallet lifter 67 up and down, the upper and lower frames 69 and 71 in the pallet support frame 75 are moved to a processing table in a plate processing machine such as a laser processing machine. It can be positioned up and down corresponding to the height position (pass line height position), and the pallets supported by the upper and lower frames 69 and 71 can be carried in and out of the plate material processing machine. is there. At this time, since the pallets on the upper and lower frames 69 and 71 can be carried in and out in a desired direction in the X-axis direction or the Y-axis direction, they are adjacent to the shelf body 3 in the X-axis direction or the Y-axis direction. A plate material processing machine can be arranged.

  And when the plate material processing machine is disposed adjacent to the shelf body 3 in the Y-axis direction, a separate elevator device 93 can be provided on the side surface opposite to the elevator device 11 so as to be movable up and down. The pallets 5 and 7 can be carried in and out of the shelf portion 9 regardless of the single-sheet taking device 19. Therefore, for example, when there is no work W on the material pallet 5, the material pallet 5 is taken out on the elevator device 93 regardless of the operation state of the one elevator device 11 or the single picking device 19, and a forklift or the like is used. Thus, the next new workpiece can be replenished onto the material pallet 5 and the efficiency can be improved.

  Now, in the configuration as described above, when the single picking device 19 is pulled into the standby shelf 21, the material pallet 5 loaded with the workpiece W is lowered on the elevator device 11 in a state where it is lowered by a conveying device such as a forklift. , The elevator device 11 is raised to a height position corresponding to the uppermost shelf 9, and the material pallet 5 is sent to the shelf 9, so that as shown in FIG. A material pallet 5 is stored in the shelf 9.

  And in the state where the empty process pallet 7 is stored in the other shelf part 9, in order to place the workpiece | work W on each process pallet 7, it is performed as follows. That is, when the single sheet pick-up device 19 is pulled into the standby shelf 21, the material pallet 5 is pulled out by the elevator device 11, and the material pallet 5 is placed on the movable lifter 95 positioned at the lower position. To do. And the pallet support slider with which the elevator apparatus 11 was equipped is pulled in from the lower side of the said material pallet 5, and the support of the material pallet 5 is cancelled | released.

  As described above, the material pallet 5 is placed on the lifter 95 and the elevator apparatus 11 is raised, and the empty processing pallet 7 is pulled out and placed on the elevator apparatus 11. After the elevator apparatus 11 is lifted as described above, the single workpiece picking device 19 picks up the workpiece W on the material pallet 5 and positions the single picking device 19 in the standby shelf 21 again. In this way, when the single picking device 19 holding the workpiece W is located in the standby shelf 21, the elevator device 11 is positioned at a height position corresponding to the standby shelf 21.

  And after carrying the empty processing pallet 7 in the standby shelf 21 and placing the workpiece W taken on the empty processing pallet 7, the processing pallet 7 is returned to the original shelf 9, The next empty processing pallet 7 is pulled out and placed on the elevator apparatus 11. As described above, when the elevator apparatus 11 pulls out the next processing pallet 7, the single picking device 19 picks up the next workpiece W on the material pallet 5 and returns to the standby shelf 21 again.

  As described above, when the single picking device 19 holds the next workpiece W, the next processing pallet 7 is carried into the standby shelf 21 and the next workpiece W is placed on the next processing pallet 7. Place and return to the original shelf 9. That is, by repeating the operation as described above, the workpieces W can be placed on all the processing pallets 7 stored in the plurality of shelves 9 in the shelf main body 3 or the required number of processing pallets 7. As described above, after the workpieces W are placed on all or the required number of processing pallets 7, the material pallet 5 is returned to the original shelf 9 by the elevator device 11.

  As described above, after the workpieces W are placed on all or the required number of machining pallets 7, the machining pallet 7 on which the workpieces W are placed is pulled out on the elevator apparatus 11, and the drawn machining pallet 7 is placed on the pallet. The lifter 67 is placed on the upper frame 69 or the lower frame 71, and is carried into the plate material processing machine via the pallet lifter 67. Then, when processing the workpiece W in the plate material processing machine (laser processing machine) 1, the next processing pallet 7 is placed in a standby state where it is placed on the upper frame 69 or the lower frame 71 of the pallet lifter 67.

  Thereafter, the processing pallet 7 on which the workpiece W (hereinafter referred to as a product) processed by the plate material processing machine is placed is returned to the pallet lifter 67, and the next processing pallet 7 in the standby state is processed into the pallet lifter 67 by plate processing. Carry in to the machine and start machining the next workpiece W. As described above, when the next workpiece W is being processed, the processing pallet 7 on which the product is placed is returned to the original shelf 9, and the next processing pallet 7 is carried into the pallet lifter 67. By setting the standby state, the processing pallets 7 on which the workpieces W are previously placed can be successively carried into the plate material processing machine and the workpieces W can be continuously processed.

  Product sorting after finishing the work W is performed as follows. That is, the processing pallet 7 on which the product is placed is pulled out by the elevator device 11 and placed on the lifter 95. Next, after the elevator device 11 is raised to a position above the horizontal guide rail 17, the single picking device 19 is lowered so as to approach the processing pallet 7 on the lifter 95, and should be sucked on the processing pallet 7. An appropriate number of work holding means 65 are positioned so as to correspond to the shape and dimensions of the product.

  Then, the product is lifted by the work holding means 65 corresponding to the product, and is transported and placed at a preset position on the product pallet on the product lifter 97 arranged in advance adjacent to the lifter 95 in the X-axis direction. That is, the product is repeatedly conveyed from the processing pallet 7 on the lifter 95 to the product pallet on the product lifter 97 by the single sheet picking device 19. At this time, products having the same directionality and the same shape and size are stacked in the same place.

  Note that the skeleton can be placed and stacked at an appropriate position on the product pallet by being cut and separated into small dimensions in advance in a plate material processing machine.

  As described above, when the processing pallet 7 on the lifter 95 becomes an empty processing pallet 7 by repeatedly carrying and stacking the products on the product pallet from the processing pallet 7 placed on the lifter 95, the one piece is removed. The device 19 enters the standby shelf 21. Then, the elevator apparatus 11 returns the empty processing pallet 7 to the original shelf 9, places the next processing pallet 7 on the lifter 95, and repeats the operation as described above. The required number of products on the processing pallet 7 can be sorted and loaded on the product pallet.

  By the way, in the above description, it has been described that the workpieces W are placed on all or the required number of processing pallets 7 in advance, and the products are sorted after the processing of all the workpieces W on the respective processing pallets 7 is completed. . However, when the next workpiece W is being processed by the plate material processing machine, it is also possible to sort the workpiece (product) that has been processed.

  That is, as described above, the processing pallet 7 on which a workpiece (product) that has been processed in the plate material processing machine is placed is unloaded onto the pallet lifter 67, and the processing pallet 7 that is in a standby state in advance is placed on the pallet lifter 67. After carrying in to a board | plate material processing machine, after the processing pallet 7 which loaded the said product is pulled out and mounted on the lifter 95 with the elevator apparatus 11, only the elevator apparatus 11 is raised. In this state, as described above, products are sorted on the product pallet by the single picking device 19, and the empty processing pallet 7 is returned to the original shelf 9. Then, the next processing pallet 7 is taken out from the next shelf 9 and loaded into the pallet lifter 67 to be in a standby state.

  As another method, as described above, after the processing pallet 7 that has been emptied by sorting the products is returned to the original shelf 9, the material pallet 5 is transferred onto the lifter 95, One piece of work W is picked up by the picking device 19. Then, the material pallet 5 is immediately returned to the original shelf 9 and an empty processing pallet 7 is carried into the standby shelf 21. Alternatively, when the empty processing pallet 7 is lowered while being supported by the elevator device 11 and becomes the same height as the standby shelf 21, the single picking device 19 is moved to the processing pallet 7 on the elevator device 11. It is also possible to place the next workpiece W on the processing pallet 7 by positioning it upward.

  Then, the processing pallet 7 on which the workpiece W is placed can be carried into the pallet lifter 67 and put in a standby state.

  That is, according to the said structure, since the side surface in which the pick-up apparatus 19 puts in / out with respect to the shelf main body 3 and the side surface in which the elevator apparatus 11 moves up and down is a common side surface, space saving can be achieved. It is. In addition, since the single sheet pick-up device also serves as a product sorting device, the product sorting area after processing is within the operation area of the single pick-up device 19, and space can be saved in this respect as well. is there.
