PURPOSE:To make a product blank possible to be stacked up higher than its receiving position in a frame, on a shifting table, by letting the frame itself in a stacking device receiving the stacked product blanks go up and down. CONSTITUTION:When a stacked blank B is fed into a conveyor 11, a frame lifting device 15 is set in motion, causing a frame 14 to go down to a delivery position L. Next, a nipping cylinder 29 is set in motion, pushing out a supporting lever 28, and the stacked blank B is held up with a supporting pin 30 and a stopper pin 26. When the conveyor 11 goes back by dint of a cylinder 21, the stacked blank B is placed on a pallet 19. The frame 14 therefore goes upward again, then returns to a receiving position M and the supporting lever 28 is also retreated to the receiving position. Likewise, a shifting table 17 moves to the left as far as a distance of width of the stacked blank B and stands ready thereat. Repeating these motions thereafter, when placement of the first stage on the pallet 19 is over, stackings of the second and third stages take place so that blanks can be stacked up higher than the receiving position M. |
