Embodiments of the present invention will be described below with reference to the drawings. 1 is a schematic perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view of a moving table. In FIG. 1, reference numeral 15 denotes a square (or rectangular) processing table provided on a processing machine, and reference pins 16 similar to the conventional one are vertically fixed to four corners of the upper surface of the processing table 15. A pedestal 17 having substantially the same shape as the processing table 15 is arranged on the right side of the processing table 15. The pedestal 17 is formed by stacking the processed plate materials W1 on top of each other, and includes a lift motor 18
The screw shaft 19 rotated by is sequentially moved downward in accordance with the stacking amount of the plate materials W1, and the level of the uppermost plate material W1 is always kept substantially constant.

Reference numeral 20 denotes a square (or rectangular) moving table, which is used as the processing table 15 and the pedestal 17.
Is arranged above the crossbar 21 so as to be slidable in the left-right direction, and is screwed to the screw shaft 23 that is normally and reversely driven by the moving motor 22 so that the worktable 15 can be moved in the left-right direction.
The drive is controlled to an upper position of the pedestal and an upper position of the receiving table 17. The moving table 20 has a flat mounting surface 2 on its upper surface.
0a, and at the same time, the reference pins 24 of the same pitch as the reference pins 16 of the processing table 15 are fixed to the four corners of the mounting surface 20a. Unprocessed plate materials W are stacked on the upper surface of the placing surface 20a, and reference holes (reference numerals are omitted) opened at four corners of the plate material W are used as the reference pins 24.
To position it.

A first suction device 25 is provided below the moving table 20. As shown in FIG. 2, the first adsorbing device 25 has a hollow chamber 25a formed therein, and a large number of suction ports 25b formed in the lower wall of the hollow chamber 25a, and the hollow chamber 25a is provided with a side wall thereof. An air suction hose 25c is connected. The air suction hose 25c makes the hollow chamber 25a a negative pressure to suck the outside air from the suction port 25b, and the suction force holds and holds the processed plate material W1 on the processing table 15. .

A lifting device 2 is provided behind the processing table 20.
6, a lifting table 27 is connected to the lifting device 26.
The lifting table 27 is arranged above the processing table 15,
The second adsorption device 28 is provided on the lower surface. This suction device 28 has suction ports 2 at four locations corresponding to the four corners of the processing table 15.
8a is formed, and an air suction hose (both not shown) is connected through a hollow chamber formed in the lift table 27. The air suction hose makes the hollow chamber a negative pressure and sucks outside air from the suction port 28a. Then, this suction force sucks and holds the uppermost unprocessed plate material W stacked on the mounting surface 20a of the moving table 20.

Next, the operation mode of the above embodiment will be described. When the screw shaft 23 is normally rotated by the moving motor 22, the moving table 20 is moved forward (moved leftward) to be positioned above the working table 15, and the first suction device 25 of the moving table 20 is operated, The plate material placed on the table 15, that is, the processed plate material W1 is adsorbed to the lower surface of the moving table 20. In this state, the elevating device 27 is lowered by the elevating device 26, and the second suction device 28 of the elevating table 27 is operated, so that the uppermost unprocessed plate material W loaded on the moving table 20 is moved to the elevating table. It is adsorbed on the lower surface of 27. Next, after raising and lowering the lifting platform 27 to raise the uppermost plate material W, the screw shaft 2 is moved by the moving motor 22.
Reverse 3 and move the moving table 20 backward (moving to the right)
The first suction device 25.
When the operation of (1) is released, the processed plate material W1 adsorbed on the lower surface of the moving table 20 is placed on the pedestal 17.

When the lifting table 27 is lowered when the moving table 20 is retracted and the operation of the second suction device 28 is released, the unprocessed plate material W sucked on the lower surface of the lifting table 27 is transferred to the working table 15. While being placed, the reference holes formed at the four corners of the plate material W are fitted to the reference pins 16 fixed upright on the processing table 15 and positioned at predetermined positions. Then, the elevating table 27 is raised and a processing machine (not shown) is operated to process the plate material on the processing table 15. After this processing is completed, the moving table 2
0, the first suction device 25, the lifting table 27, and the second suction device 28 are again operated in the same manner as described above to supply and remove the plate material (W, W1) to and from the processing table 15. Each time the processed plate material W1 is supplied from the moving table 20 to the pedestal 17, the lift motor 18 is operated, and the pedestal 17 is sequentially moved downward via the screw shaft 19 in accordance with the stacking amount of the plate materials W1. Then, the level of the uppermost plate W1 is always kept substantially constant. The movement of the moving table 20 in the left-right direction may be performed by a cylinder mechanism.
