PURPOSE:To deliver a load between conveyers by a fixed inner cylinder having a pin fixed on the outer surface and a cylinder inside thereof and an outer cylinder having a load supporting arm and a pin guide groove on the side thereof, which is secured to the end of the cylinder. CONSTITUTION:When a cylinder 3 is operated, an outer cylinder 1 rises, and a load supporting arm rises herewith to lift up a load from a conveyer supporting arm. The outer cylinder 1 is rotated along a guide groove 7 by a pin 8 of an inner cylinder 2 when it rises. The guide groove 7 is V-shaped, and when the pin 8 goes toward a hollow portion, it pushes a second coupling lever 11. Whereupon, a guide lever 14 is turned to keep the pin 8 from moving backward in the guide groove, whereby the pin is guided from the hollow portion of the V-shaped groove in the correct direction. |
