After that, when the grasped resin plate R reaches the pallet P, the lateral feed conveyor 8 drives the support table 82 by the opening / closing cylinder 85 in the direction of separating from the pallet P, and also the chuck. The member 86 is oscillated in a direction in which the tip ends thereof are separated, and the resin plates R are stacked on the pallet P. Similarly, the resin plates R are sequentially stacked on the pallet P, and the elevating table 74 descends every time the resin plates R are stacked in accordance with the thickness of the resin plate R to lower the height of the pallet P, that is, The height is controlled so that the upper surface of the resin plate R is constant. Then, when the resin plates R are piled up on the pallet to a specified height, the carry-out conveyor 7 lowers the lifting table 74 to a position where the belt 71 at the starting end portion is continuous at the same height as the belts at other portions, The belt 71 is driven to travel to carry out the pallet P.
