PURPOSE:To efficiently stack containers, by mounting an expansible and contractible unit on a swing arm movable vertically and rotatable horizontally, so that the unit can be moved along the arm and by fitting the expansible and contractible unit with a rotary head having a grasping means. CONSTITUTION:When a container 1 such as a fish box brought by a roller conveyor 2 is grabbed by a grasping means on a rotary head 8, a column 5 is moved up by a vertical drive means 11 including a hydraulic cylinder 25 and is rotated by a horizontal turning means 10 including a motor 19, so that a swing arm 6 is elevated and turned simultaneously. At that time, an expansible and contractible unit 7 is moved along the arm 6 to carry the container 1 to a prescribed position over a pallet 3. The arm 6 is then moved down to put the container 1 on the pallet 3. After that, the grasping means releases the container 1. The swing arm 6 is thereafter elevated and turned again to a position over the conveyor 2 to handle another container 1. |
