[Work]

Since the device of the present invention is configured as described above, it is opened to the outside of the deposition site during the normal deposition operation (FIG. 3A), as shown in the operating modes in FIGS. 3A to 3D. The intermediate holding bars 5a, 5b that are in contact with each other, before the stacked plate-shaped bodies 3a, 3b are carried out to the outside of the machine, first look at the interval between the stacking operations and the middle holding bars 5b on the front side in the transport direction. Only project into the deposition area (see Figure 3B). In this case, since it is not projected to the center holding bar 5a on the rear side in the transport direction, the rear side in the transport direction of the plate-like body 3 in the dropping process is not affected by any obstacle, and the stacked plate-like bodies 3a on the lower side, Deposited on 3b. Then, slightly behind the operation of the middle holding bar 5b on the front side in the conveying direction, the remaining middle holding bar 5a on the rear side in the conveying direction is projected into the depositing place after a time normally required for landing of about 0.3 seconds (3C
(See the figure), if the subsequent plate-like body 3 is continuously charged in this state, the subsequent plate-like body 3 is sequentially received on the middle holding bars 5a and 5b (see FIG. 3D). Then, the plate-like bodies 3a and 3b, which are filled up in the meantime, are extruded from above the lifting table and carried out of the machine.

Although not shown, when the plate-shaped bodies 3a, 3b that have been fully deposited on the lifting table have been carried out, the lifting table at the deposition location is returned to the uppermost position. Opening the middle holding bars 5a, 5b at once, the middle holding bars 5a, 5b
Since the plate-like body 3 temporarily received above is dropped onto the elevating table and the normal stacking operation is performed as it is, when the apparatus of the present invention is used, a conveyor is used. It is not necessary to temporarily suspend the carrying operation of the plate-like body during the carry-in process for carrying out the fully-loaded plate-like body to the outside of the machine, and as described above, the intermediate holding bar 5a, Since 5b controls the rear side in the transport direction slightly behind the front side in the transport direction so as to project into the deposition place, it is just before being deposited on the lower plate-shaped bodies 3a, 3b. It is possible to safely avoid an unexpected situation in which the rear side of the plate-shaped body 3 in the transport direction and the middle holding bar 5a on the rear side of the transport direction collide with each other.
