2. Description of the Related Art Conventionally, for example, as shown in FIGS. 5 and 6, a laser processing system 101 as a plate material processing system vertically moves a plurality of shelves 103 for accommodating a pallet P on which a work W is loaded. Multiple storage shelves 1
05 is erected. The side of this storage shelf 105 (FIG. 5,
An elevator 107 for moving the pallet P in and out of the shelf 103 and moving it up and down is provided on the left side in FIG.

A work piece take-up device 109 is disposed adjacent to the storage shelf 105, and the work piece take-up device 10
In FIGS. 5 and 6 of FIG.
One and a plurality of unloading and stacking devices 113 are arranged.
In addition, a guide rail 117 is provided for moving the work piece taking apparatus 109 and the unloading unloader 115 in the horizontal direction in FIG.

With the above configuration, a pallet P selected from the pallets P stored in the plurality of shelves 103 in the storage shelf 105 is pulled out to the elevator 107. Next, the elevator 107 is lowered and stopped at the lowest position of the storage shelf 105. A pallet P loaded with works W from an elevator 107 stopped at the lowest position of the storage shelf 105 is provided with a vertically movable pallet table 119 provided below the work piece take-up device 109.

With the above configuration, the pallet P loaded with the works W stored in the plurality of shelves 7 in the storage shelf 3 is taken out and laser-processed by the laser processing machine 35. The operation up to the integration into 33 will be described.

First, the elevator 25 is moved up and down to be positioned at the required position of the shelf 7. Thereafter, the traverser 25 is moved rightward in FIG. 2 in the Y-axis direction, and the hook 31 is engaged with the pallet P. By moving the traverser 25 to the left in FIG. 2 in this state, the pallet P loaded with the work W is pulled out onto the elevator 25.

Next, the elevator 25 is lowered and stopped at the position of the lowest shelf 7A in the storage shelf 3.
By moving the traverser 29 to the right in FIG. 2 in this state, when the pallet P is temporarily held on the pallet holding frame 19 on the lowermost shelf 7A,
The hook 31 comes off the pallet P and is returned to the original position.

The vertical cylinder 1 of the work piece taking device 9
1 is operated to lower the vacuum pad 17 via the piston rod 13 so that the uppermost work W of the plurality of works W is sucked and raised. The table carriage 21 is moved from the side position of the storage shelf 3 to the position of the lowermost stage 7A while the work W is attracted and lifted upward. Then, when the work W is separated from the vacuum pad 17 of the single workpiece pick-up device 9 and placed on the support frame 23 of the table carriage 21 on the table carriage 21 at the position of the lowermost stage 7A, the table carriage 21 is moved to the lowermost stage. Moved from the shelf 7 to the side of the storage shelf 3 (FIG. 1).
To the right).

In this state, the loader / unloader 43
2 is moved to the right side in FIG. 2 and the up / down cylinder 45 is operated to lower the forks 49 via the piston rods 47. Each of the forks 49 enters between the support frames 23, and the work W is placed on the forks 41. When placed, the fork 49 rises and the table cart 21
Is transferred onto the fork 41 away from the support frame 23.

With the work W transferred to the fork 49, the loader / unloader 43 is guided by the guide rail 41 to the right in FIG. 2 in the Y-axis direction, and moves on the work table 51 of the laser processing machine 35. The work W is clamped by the work clamp 59 while the work W is changed from the work 49. In this state, the drive motors 55 and 65 are driven to rotate the ball screws 53 and 63, so that the carriage 57 moves in the X-axis direction and the laser processing head 67 moves in the Y direction.
The laser processing head 67 is moved in the axial direction.
Laser processing is performed on a desired position of the workpiece W by the laser beam irradiated from the.

During the laser processing, one second work W is taken out in the same manner as described above, and is placed on the table carriage 21 and kept on standby.

When the laser processing of the work W is completed, the work W is again moved by the loader / unloader 43 so that the fork 49 is put under the work W on the work table 51 and is put on the fork 49 to be raised and the work clamp is performed. 59 is unclamped. When the loader / unloader 43 is moved to the left in FIG. 2, the fork 49 passes through the space between the stoppers 37.
The upper work W is stopped by being hit by the stopper 37. When the forks 49 are completely removed from the work W, the work W falls onto the work accumulation means 33 and is accumulated.

The fork 49 of the loader / unloader 43
Picks up the second work W of the table cart 21 which has retreated from the lowermost shelf 7A in the storage shelf 3 and carries it into the laser processing machine 35. The laser processing is performed until there is no more.

When there is no more work W on the pallet P and further laser processing is performed, the operation is performed in the manner described above from the operation of pulling out the pallet P from the shelf 7 of the storage shelf 3 again.

Therefore, as compared with the installation space in the state shown in FIG. 1 and the conventional installation space shown in FIG. 6, the installation area is reduced and unnecessary space can be eliminated. In addition, one side of the laser processing machine 35, that is, the upper side in FIG. 1 is an empty space, and a space for an operator to enter is increased, and workability during offline operation, that is, workability such as manual unloading of a work can be improved. .

As shown in FIG. 4, even if the number of the laser beam machines 35 is increased by one and the number is increased to two, the same operation and effect as in FIG. 1 can be obtained.

The present invention is not limited to the above-described embodiment of the present invention, but can be embodied in other forms by making appropriate changes. Although a laser processing machine has been described as an example of a plate processing machine, other plate processing machines such as a punch press may be used.

[0035]

As will be understood from the above description of the embodiments of the present invention, according to the first aspect of the present invention, a pallet on which a work is loaded is stored on a plurality of shelves of a storage shelf. After the pallets selected from the plurality of shelves are pulled out by the traverser provided in the pallet transfer means, the pallet transfer means is lowered, and the pallets are transferred to the lowest stage in the storage shelf. The transferred pallets are temporarily held by pallet holding means provided at the bottom of the storage shelf.

The work on the pallet temporarily held by the pallet holding means is lifted upward by the work piece picking means, and the work table means is positioned below the work piece picking means from the side of the storage shelf. It is moved to and stopped. Then, when the work is lowered from the work piece taking means and placed on the work table means, the work table means is moved to the side of the storage shelf.

In this state, the work on the work table means is gripped by the work carry-in / out means waiting at the side position of the pallet transfer means, and the work carry-in / out means is moved to the plate material processing machine to transfer the work. The workpiece is placed at a predetermined position on the plate processing machine, and a desired plate processing is performed on the work by the plate processing machine. The processed work is carried out to the work collecting means by the work carrying-in / out means by the plate material processing machine. Since the work accumulating means is provided at this position, the processed work is accumulated.

Thus, it is possible to reduce the installation space and to improve the workability during off-line operation as compared with the related art.
