That is, a guide rail 7 is provided at the lower portion of the shelf body 3, and the work pallet housing shelf 5 </ b> A is configured above the guide rail 7. A single sheet picking device 21 for picking up a single piece of the plate-like work W loaded on the work pallet P is provided at the upper part of the work pallet storage shelf 5A so as to be movable up and down. . In addition, since the structure of this kind of single picking apparatus 21 is known, description about the single picking apparatus 21 is abbreviate | omitted.

  In order to support the workpiece W picked up by the single picking device 21, a movable table capable of reciprocating between the vertically moving region of the elevator device 9 and the raised lower position of the single picking device 21. 23 is provided. More specifically, at a position higher than the work pallet P housed in the work pallet housing shelf 5A, the work pallet housing shelf 5A is provided with a slider 25 that supports the moving table 23 on the upper part so as to be movable back and forth. It has been. Further, a reciprocating device for reciprocating the slider 25 in the front-rear direction is provided.

  The slider 25 is movable to a front and rear guide member (not shown) horizontally provided on the left and right sides of the work pallet housing shelf 5A, and the elevator device 9 moves up and down from the work pallet housing shelf 5A. (Region) is supported so as to protrude freely. In other words, the moving table 23 is provided so as to protrude from the work pallet receiving shelf 5A to the front side of the shelf body 3. As the configuration of the reciprocating device, for example, a fluid pressure cylinder such as an air cylinder can be adopted. However, in the present embodiment, the configuration is as follows.

  That is, drive sprockets 29 that are rotated forward and backward by the motor 27 are rotatably provided on both the left and right sides of the rear side of the work pallet storage shelf 5A. A driven sprocket 31 corresponding to the drive sprocket 29 is rotatably provided on both the left and right sides of the front side in the work pallet storage shelf 5A. An endless member 33 is hung around. The endless member 33 and the rear end of the slider 25 are appropriately connected.

  Therefore, when the motor 27 is driven and the endless member 33 is rotated forward (counterclockwise in FIG. 1), the moving table 23 moves to the left in FIG. The elevator device 9 protrudes in the region where the elevator device 9 moves up and down, that is, the front side of the shelf body 3. Then, by rotating the endless member 33 in the reverse direction, the moving table 23 protruding into the vertical movement region of the elevator apparatus 9 is moved downward from the single-sheet taking apparatus 21 in the raised state, and the work pallet storage shelf 5A. It can be pulled in.

  As already understood, when the single picking device 21 picks up the workpiece W on the work pallet P in the work pallet receiving shelf 5A, the moving table 23 is moved up and down by the elevator device 9. Projecting to the area (front side of the shelf body 3), the upper side of the work pallet P is open. Therefore, the single picking device 21 can pick up a single piece of the work W on the work pallet P without interfering with the moving table 23.

  As described above, when the single picking device 21 picks up the workpiece W and moves up, the moving table 23 is drawn to a position below the single picking device 21 that picked up the single piece, and the moving table 23 is placed on the moving table 23. The workpiece W is placed. The workpiece W placed on the moving table 23 is transported so as to be movable in the left-right direction (X-axis direction) in the work pallet receiving shelf 5A at substantially the same height as the single-sheet pick-up device 21. It is conveyed by the means 35 to the board | plate material processing machine (illustration omitted) arrange | positioned adjacent to the left-right direction, and is processed by the said board | plate material processing machine.

  Since the structure of the conveying means 35 is well known, the detailed description of the conveying means 35 is omitted. The conveying means 35 has a function of feeding and carrying a workpiece to and from the plate material processing machine and a function of carrying out a product processed by the plate material processing machine from the plate material processing machine. Therefore, the transport means 35 constitutes a work carry-in means when supplying and carrying in a work, and constitutes a product transport means when carrying out a product.

  As described above, when the work carried into the plate material processing machine is processed by the transport unit 35, the processed product is transported onto the moving table 23 by the transport unit 35. In order to load the processed product on a pallet (product pallet), an empty product pallet P taken out from an appropriate storage shelf 5 of the shelf body 3 is placed on the elevator device 9. In order to load the product on the moving table 23 on the product pallet P, the elevator device 9 is in a state of being lowered to a position lower than the height position at which the moving table 23 protrudes.

  When the elevator device 9 is lowered to a low position, the moving table 23 on which the product is placed protrudes from the work pallet housing shelf 5A to a position above the elevator device 9. Thereafter, product transfer means for transferring the product on the moving table 23 onto the product pallet P when the moving table 23 is pulled into the work pallet storage shelf 5A is provided.

  As the product transfer means, it is also possible to adopt a configuration such as a transfer robot that holds the product on the moving table 23 and transfers it onto the product pallet P. However, in the present embodiment, a configuration is adopted in which the product on the moving table 23 is prevented from returning integrally when the protruding moving table 23 returns to the work pallet receiving shelf 5A. That is, a vertical operation device 37 such as a fluid pressure cylinder is provided on the upper side of the moving table 23 and in front of the work pallet storage shelf 5A. A lifting member such as a scraper is provided with a stopper member 39 such as a scraper.

  Therefore, when the moving table 23 on which the product is placed protrudes above the product pallet P placed on the elevator device 9, the moving table 23 moves in a state where the stopper member 39 is lowered to prevent the product from returning. By returning the table 23 into the work pallet storage shelf 5 </ b> A, the product on the moving table 23 is dropped and loaded on the product pallet P on the elevator apparatus 9.

  The work W on the work pallet P in the work pallet storage shelf 5A is supplied and loaded into the plate material processing machine, the processed product is unloaded and loaded on the product pallet P on the elevator device 9 repeatedly. When there is no work on the work pallet P and the processing is completed, the elevator apparatus 9 is raised, and the product pallet P loaded with products is stored in an empty storage shelf 5. Thereafter, the elevator device 9 descends, and an empty work pallet P in the work pallet storage shelf 5A is taken out onto the elevator device 9, and this work pallet P is stored in a separate empty storage shelf 5.

  Next, the elevator device 9 is positioned at a position corresponding to the storage shelf 5 in which the work pallet P loaded with the workpiece to be processed next is stored (stored), and the work pallet P is moved onto the elevator device 9. . Then, the work pallet P is stored in the work pallet storage shelf 5A, the next work is supplied to the plate material processing machine, and the processing of the next work is started. As described above, when the processing of the next workpiece is started, the elevator apparatus 9 takes out the above-mentioned empty workpiece pallet P and uses this workpiece pallet P as a product pallet P for loading the next product. is there.

  As understood from the above description, since the product pallet P is placed on the elevator device 9 and the elevator device 9 is used as a product accumulation position, the occupied area of the shelf device 1 is the shelf body 3 and the elevator device. 9 is an area occupied by two elements of the vertically moving space, so that the overall configuration can be saved.

  Further, the work pallet storage shelf 5A is provided with the single picking device 21 and the conveying means 35, and the single picking device 21 and the conveying means 35 are provided with substantially the same height. The height dimension of the work pallet storage shelf 5A can be suppressed, and the overall height of the shelf device 1 can be suppressed.

  Further, there is no need for a lifter or the like for moving the work pallet P up and down in the work pallet receiving shelf 5A, and the configuration can be simplified.

  In addition, this invention is not restricted only to embodiment mentioned above, It can implement with another form by making an appropriate change. That is, in the above description, it has been described that the pallets P loaded with workpieces and the pallets P loaded with products are stored in the respective storage shelves 5 of the shelf body 3 in the shelf device 1. However, it is also possible to use the shelf device 1 as a configuration in which the shelf device 1 that supplies workpieces is arranged on one side of the plate material processing machine and the shelf device 1 that stores products is arranged on the other side of the plate material processing machine. Is possible. In this case, in the shelf device used as a shelf device for storing products, the single-sheet pick-up device can be omitted.
