ABSTRACT:
There are provided carrying device and method capable of high-speed pick-up and travelling operation of a carrier. The carrier is provided with a holder bracket movable back and forth, in which claw members for grasping a material are held, and a driver mechanism for stroking g the holder bracket and a driver mechanism for opening and closing the claw members are attached to the carrier body. A movable portion in the carrier can be made lighter in weight. An electric wiring cord to be connected to the movable portion can be eliminated or made thin and light enough. This allows the carrier to move at a high speed. The carrier is held at the intersection of a pair of crossing moving bars and moved to a target position by moving both the moving bars. No motor needs to be provided in the carrier for driving the carrier, so that the movable portion moving together with the carrier can be made lighter in weight, thereby speeding up the movement of the carrier. The exchange of control signals between the carrier and carrying controller is made by serial communication, preferably, wireless or optical communication. Also provided is a control method for stopping the carrying operation by detecting a material which projects from the shelves.
