At the lower end of the elevating body 34, a suction part 36 that rotates by a cylinder unit 35 is engaged. The suction portion 36 is provided with a suction cup 37 that directly suctions the plate glass G.

The operation of the crowding device constructed as described above will be described below.

First, the pallet 5 conveyed on the conveyor 1 is lifted together with the platform 4 by the lifter 6 to the position shown in solid line in FIG. Then, the movable body 13 of the crowding device retreats, rotates the first and second swing arms 16, 17 and the suction part 18 by a predetermined angle, and rotates the main suction cup 22 of the suction part 18.
And the opening board 27 is made to face the plate glass G stacked on the pallet 5.

Thereafter, the small plate 21 of the suction section 18 is advanced toward the glass plate G by the operation of the cylinder unit 20, and the main suction cup 22 suctions the glass plate G from above the interleaf paper 8.

Thereafter, the movable body 13 is moved forward while holding the frontmost sheet glass G on the pallet 5 together with the interleaf sheet 8, and the first and second swinging arms 16° 17 and the suction part 18 are moved at a predetermined angle. Rotate the plate glass G to face the suction cup 37 of the suction unit 36 as shown in FIG.
The suction cup 3 moves forward and presses the plate glass G onto the suction cup 37.
7, the side of the glass plate G where the interleaf paper 8 is not attached is sucked.

Next, the interleaving paper 8 is sucked by the opening plate 27, and the suction by the main suction cup 22 is released. As a result, the plate glass G is delivered to the suction section 36 side, and the interleaf paper 8 remains on the suction section 18 side. Therefore, regarding the plate glass G, the elevating body 34 is lowered by the operation of the cylinder unit 33, the suction part 36 is turned downward by the operation of the cylinder unit 35, and then the suction state is released, so that it is transferred onto the conveyor 2 and then combined. For the paper 8 the first and second swinging arms 1
6.17 is rotated backward by a predetermined angle, and when the suction part 18 is positioned above the paper box 3, the suction state by the opening plate 27 is released, and the paper 8 is dropped into the paper box 3, and a series of plate glasses are placed. The loading means is completed.

(Effects of the Invention) As explained above, according to the present invention, the main suction cup that suctions the sheet glass from above the gold paper and the opening board that suctions only the interleaving paper are provided in the sheet glass gathering device, which makes it possible to replace the conventional one. Thus, the interleaving paper can be reliably peeled off from the glass plate without the need for a special device for peeling it off, and even if thin and weak paper such as low-quality paper is used as the interleaving paper.

Furthermore, the interleaving paper can be dropped into the interleaving paper box during a series of operations for transferring plate glass, which is advantageous in terms of efficiency since there is no waste in the overall operation.
