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. 3), the moving table 23 moves to the left in FIG. The elevator device 9 protrudes in a 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 said board | plate material processing machine WM 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 transport means 35 has a function of supplying and carrying a workpiece to the plate material processing machine WM and a function of unloading a product processed by the plate material processing machine WM from the plate material processing machine WM. 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.

  By the way, as shown in FIG. 3, the conveying means 35 is provided on the rear side (right side in FIG. 3) in the work pallet receiving shelf 5A, and before and after the work movement positioning device MH in the plate material processing machine WM. Since the origin position in the direction (Y-axis direction) is on the rear side, when the workpiece W is conveyed (carried in) to the plate material processing machine WM by the conveying means 35, the rear edge of the workpiece W is moved to the conveying means 35. To the transport reference position L / UL (see FIG. 5).

  Therefore, the shelf apparatus 1 includes a workpiece edge detection means 41 (see FIG. 4) for detecting the position of the trailing edge of the workpiece W in the workpiece pallet storage shelf 5A. More specifically, the workpiece edge detecting means 41 positions the pallet P at the pallet reference position in the front-rear direction in the workpiece pallet receiving shelf 5A, and the workpiece W edge detection means 41 is positioned at the workpiece reference position on the pallet P. In the state where the left edge in FIG. 5 is positioned, a set value memory 43 that stores a known dimension value L1 (see FIG. 5B) from the front edge of the workpiece W to the conveyance reference position L / UL. It has.

  Then, the moving table 23 is moved in the front-rear direction from the origin position in the front-rear direction (the position shown in FIG. 5A) where the rear end edge of the moving table 23 is located behind the transport reference position L / UL. Position detecting means 45 for detecting the moving position of the moving table 23 in the front-rear direction when the moving table 23 is moved, and when the work W is placed on the moving table 23 and moved back and forth, Work detection means 47 for detecting the edge of W in the front-rear direction is provided.

  The position detecting means 45 is suitably used, such as a rotary encoder (not shown) provided in the motor 27 for moving the moving table 23 back and forth, or a linear scale for directly detecting the position of the moving table 23 moving back and forth. It is possible to employ a detection device. And as the said work detection means 47, it is also possible to employ | adopt the imaging means which images the said workpiece | work W on the said movement table 23 and the said movement table 23. FIG. However, in this embodiment, in order to simplify the configuration, a configuration in which the stopper member (scraper) 39 is provided with a sensor such as an optical sensor (not shown in FIG. 3) is employed.

  Therefore, when the work W is placed on the moving table 23 and moved back and forth, the position detecting means 45 detects the moving position of the moving table 23 from the home position in the front-rear direction, and the work detecting means 47 The workpiece edge detection means 41 is provided with a width dimension L2 in the front-rear direction of the workpiece W based on the movement position of the moving table 23 when the front edge of the workpiece W is detected and the movement position when the rear edge is detected. It can be calculated by the calculating means 49. Further, the calculation means 49 can calculate the dimension L3 from the rear end edge of the workpiece W on the pallet P to the conveyance reference position L / UL by (L1-L2).

  As already understood, when the work W on the pallet P is picked up by the single picking device 21 and then placed on the moving table 23, as shown in FIG. Then, the moving table 23 is moved forward from the origin position in the front-rear direction by a dimension L3. Then, by returning the moving table 23 to the origin position, the rear end edge of the workpiece W coincides with the transport reference position L / UL of the transport means 35.

  That is, after the pallet P on which the workpiece W is placed at the reference position is positioned at the reference position in the work pallet receiving shelf 5A (see FIG. 5A), the moving table 23 is controlled under the control of the table movement control means 51. Is moved forward from the origin position in the front-rear direction. Then, one piece of the workpiece on the pallet P is picked up by the single picking device 21 (see FIG. 5B). Thereafter, the moving table 23 is returned to the original origin position, and the workpiece W picked up by the single picking device 21 is placed on the moving table 23 (see FIG. 6A).

  Next, when the movement table 23 is moved forward from the origin position under the control of the table movement control means 51 (see FIG. 6B), the position detection means 45 moves the movement table 23 in the front-rear direction. Detect position. Further, based on the movement position when the front end edge of the work W on the moving table 23 is detected by the work detection means 47 and the movement position when the rear end edge is detected, the width dimension L2 in the front-rear direction of the work W is calculated. Calculated by means 49. Further, the calculation means 49 calculates a dimension L3 from the rear end edge of the workpiece W on the pallet P to the conveyance reference position L / UL.

  As described above, after obtaining the width dimension L2 of the workpiece W in the front-rear direction, the moving table 23 is returned to the origin position again (in the imaginary line state in FIG. 6B), and the workpiece W on the moving table 23 is restored. Is picked up again by the single picking device 21. When the workpiece W is in a lifted state, under the control of the table movement control means 51, the movement table 23 is moved and positioned from the origin position in the front-rear direction by the dimension L3 (FIG. 7 ( A)). Then, after the work W is placed on the moving table 23, the moving table 23 is returned to the original position so that the trailing edge of the work W on the moving table 23 matches the transport reference position. (See FIG. 7B).

  Therefore, after that, the work W on the moving table 23 is carried into the plate material processing machine WM by the transport means 35, so that the rear end edge of the work W matches the reference position of the work movement positioning device MH in the plate material processing machine WM. It is carried in in the state that was done. Therefore, relative movement and positioning of the workpiece W with respect to the machining position WP can be smoothly performed by the workpiece movement positioning device MH.

  In the above description, the case where the workpiece W is placed on the moving table 23 and the moving table 23 is moved in the front-rear direction to obtain the width dimension L2 in the front-rear direction of the workpiece W has been described. However, when the width dimension L2 of the workpiece W is measured and input from the input means 53 to the calculation means 49, the operation for obtaining the width dimension L2 of the workpiece W can be omitted to calculate the dimension L3. Is. Accordingly, after the workpiece W is picked up by the single picking device 21, the moving table 23 is immediately moved forward by the dimension L3, and the workpiece W is placed on the moving table 23. Then, the moving table 23 is returned to the original origin position.

  As understood from the above description, after the workpiece W is lifted by the single picking device 21, the moving table 23 is positioned in the front-rear direction, and the workpiece W is placed on the positioned moving table 23. By returning the moving table 23 to the origin position, the rear end edge of the workpiece coincides with the transport reference position L / UL. Therefore, the moving table 23 is a simple configuration that moves between the position where the moving table 23 protrudes toward the front side of the shelf body 3 and the position where it moves into the shelf body 3, and is far behind the transport reference position L / UL. Even if it cannot move in the direction, the rear end edge of the workpiece W can be easily adjusted to the conveyance reference position L / UL.

  As already understood, in some cases, it is possible to place the workpiece W in a state in which the rear end edge of the workpiece W slightly protrudes rearward from the moving table 23. In this case, the origin position in the front-rear direction of the moving table 23 can be set to the front side of the transport reference position L / UL. That is, in the relationship with the transport reference position L / UL, the origin position in the front-rear direction of the moving table 23 can be set to a desired position.
