  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 conceptually and schematically show a material shelf device and a plate material processing system according to an embodiment of the present invention. It is explanatory drawing and a plane explanatory drawing.

  In the same manner as in a normal material shelf device, the material shelf device 1 has a plurality of storage shelves 3 in which a pallet P on which plate-like workpieces W are stacked (stacked) can freely enter and exit in a plurality of stages and in the left and right directions (in FIG. The shelf frame 5 is provided in a plurality of rows in a direction perpendicular to the vertical direction. On the front side (right side in FIG. 1) of the shelf frame 5, a stacker crane 7 for entering and exiting the pallet P with respect to each storage shelf 3 is provided.

  The stacker crane 7 is guided by a guide rail 9 that is long in the left-right direction and can move (run) in the left-right direction, and can be positioned to a position corresponding to the row of the storage shelves 3 provided in the shelf frame 5. (Running) A gantry 11 is provided. The traveling (moving) pedestal 11 is provided with an elevating pedestal 13 that can be moved to a height position corresponding to each of the storage shelves 3, like the general stacker crane 7. The elevator 13 is provided with a traverser 15 for moving the pallet P in and out of the storage shelves 3 of the shelf frame 5 so as to be movable back and forth.

  Further, on the lifting platform 13, a single picking means 17 for picking up the workpiece W loaded on the pallet P drawn from the storage shelf 3 onto the lifting platform 13 by the traverser 15. Is provided. More specifically, a telescopic mechanism 23 that can be expanded and contracted in the front-rear direction is provided on the lower surface of an elevating member 21 that is moved up and down by an elevating actuator 19 such as a fluid pressure cylinder provided on the left and right sides of the elevating platform 13. In the telescopic mechanism 23, a plurality of work holding means 27 such as a vacuum pad and a magnet that can hold the plate-like work W are provided on the lower surface of the longitudinally moving member 25 that moves in the front-rear direction.

  With the above configuration, for example, under the control of a control device such as a CNC device, the traveling platform 11 is moved in the left-right direction and the lifting platform 13 is moved up and down to move up and down to a position corresponding to the storage shelf 3 at a desired position. Position the gantry 13. Thereafter, the pallet P is pulled out from the storage shelf 3 to the lifting platform 13 by a traverser 15 provided on the lifting platform 13 so as to be movable back and forth.

  Then, the lifting / lowering member 21 in the one-sheet picking means 17 is lowered by operating the lifting / lowering actuator 19 and the work holding means 27 holds the uppermost work W loaded on the pallet P. As a result, the workpiece W on the pallet P can be picked up. Thereafter, by returning the pallet P into the original storage shelf 3, only one workpiece W can be taken out by the single picking means 17.

  As already understood, the pallet P is pulled out from the storage shelf 3 in the shelf frame 5 onto the lifting platform 13 of the stacker crane 7, and the workpiece loaded on the pallet P by the single picking means 17 provided in the lifting platform 13. Since it is for taking a single piece of W, it is not necessary to put the holding means 27 etc. in the single piece picking means 17 into the storage shelf 3, and the work W is placed at the height of the storage shelf 3 relative to the pallet P. Can be stacked (stacked). Therefore, the storage rate of the work W with respect to the storage shelf 3 can be increased.

  Further, since the lifting platform 13 is provided with the single picking means 17, when the pallet P is pulled out from the storage shelf 3 onto the lifting rack 13 and the lifting rack 13 is moved up and down to a predetermined position, the single picking means 17. Thus, the workpiece W can be picked up and preparations for supplying the workpiece W to the plate material processing machine in the next process can be performed, and the work efficiency can be improved.

  In order to process the workpiece W picked up by the single picking means 17, an appropriate area such as a turret punch press or a laser processing device is provided in front of the horizontal movement area of the stacker crane 7. A plate material processing machine 29 is arranged, and a workpiece carry-in device for transferring the workpiece W transferred from the material shelf device 1 into the plate material processing machine 29 between the material shelf device 1 and the plate material processing device 29. 31 is arranged.

  The work loading device 31 includes a work direction changing means 33 for changing the direction of the work W transferred by the single picking means 17 and carrying it into the plate material processing machine 29. More specifically, a guide portion 37 (see FIG. 2) in the front-rear direction is provided on one side in the left-right direction of the gantry 35 that supports the workpiece W in the workpiece carry-in device 31, and the guide portion 37 includes a slider. 39 is supported movably back and forth.

  On the slider 39, a swivel base 41 is provided so as to freely move up and down and horizontally. A horizontal swivel arm 43 is integrally attached to the swivel base 41, and a work clamp capable of holding the work W transferred by the single picking means 17 on the stand 35 on the swivel arm 43. , An appropriate work holding means 45 such as a vacuum pad and a magnet is provided.

  With the above configuration, as described above, after the workpiece W is picked up by the single picking means 17, the longitudinally moving member 25 in the telescopic mechanism 23 is moved back and forth to move onto the gantry 35 in the workpiece loading device 31. By moving, the workpiece W can be transferred onto the gantry 35 of the workpiece loading device 31. After the work W on the gantry 35 is held by the work holding means 45 in the work carry-in device 31, the slider 39 moves back and forth along the guide portion 37, and the swivel base 41 turns horizontally. The direction of the workpiece W is changed and carried into the plate material processing machine 29.

  By the way, in a plate material processing machine 29 such as a punch press or a laser processing machine, for example, the workpiece W is clamped on one side edge in the longitudinal direction of the workpiece W of a standard material by a work clamp 29C provided in the plate material processing machine 29. It is common to perform this processing. Further, when storing the workpiece W of the standard material in the storage shelf 3 in the material shelf apparatus 1, the workpiece W is usually stored so that the longitudinal direction of the workpiece W is the left-right direction.

  Therefore, when the work W taken out by the single picking means 17 is carried into the plate material processing machine 29 without changing its direction, the work W transferred from the single picking means 17 to the work carry-in device 31 is shifted left and right. The workpiece W is loaded into the plate material processing machine 29 arranged in the left-right direction of the workpiece loading device 31 from the left-right direction. In other words, the plate material processing machine 29 is arranged in the left-right direction of the workpiece carry-in device 31 and is long in the left-right direction. Therefore, when an appropriate number of plate material processing machines 29 and workpiece carry-in devices 31 are to be arranged on the front side of the material shelf device 1, the right and left position dimensions of the appropriate plate material processing machines 29 and workpiece carry-in devices 31 are the materials. It may be larger than the dimension in the left-right direction of the shelf device 1.

  However, according to the present embodiment, the workpiece carry-in device 31 carries out the direction change (for example, 90 ° direction change) of the workpiece W transferred by the single piece picking means 17 and carries it into the plate material processing machine 29. Therefore, the plate material processing machine 29 can be arranged on the front side of the work loading device 31. Therefore, the arrangement relationship of the material shelf device 1, the workpiece carry-in device 31, and the plate material processing machine 29 becomes the arrangement relationship in the front-rear direction, and the occupation area in the factory can be reduced.

  By the way, the present invention is not limited to the embodiments as described above, and can be implemented in other forms by making appropriate changes. For example, when the storage shelf 3 in the material shelf device 1 is one row, the guide rail 9 is not necessary, and the traveling rack 11 is fixed to the front side of the material shelf device 1. it can.

  Further, when the height of the workpiece W loaded on the pallet P becomes low and the longitudinal movement member 25 in the single picking means 17 can enter the storage shelf 3, the pallet P is pulled out on the lifting rack 13. It is also possible to allow the workpiece W to be picked up from the pallet P in the storage shelf 3 by allowing the forward / backward movement member 25 to enter the storage shelf 3.

  As can be understood from the above description, since the stacker crane 7 in the material shelf device 1 is configured to include the one-piece picking means 17 on the lifting platform 13 that can move up and down, as described above, the material shelf device 1. The storage rate of the work W with respect to the storage shelf 3 can be improved. Further, when a plurality of plate material processing machines 29 are arranged in the left-right direction, the stacker crane 7 is moved in the left-right direction along the guide rail 9 without moving up and down the lifting platform 13, One workpiece W is picked up from the pallet P, and the workpiece W can be supplied to the plate material processing machine 29 one after another. Therefore, when the workpieces W on the same pallet P are successively processed, the workpiece W can be efficiently supplied to the plate material processing machine 29.
