Abstract
A multi-level hand apparatus includes a plurality of hands arranged in a vertical direction, and a plurality of clamp members disposed at the plurality of hands, respectively. Each of the clamp members is movable in a forward-rearward direction to clamp and release a workpiece. The apparatus further includes a movable head member extending in the vertical direction. Each clamp member includes a fixed spring receiving member, a movable spring receiving member movable in the forward-rearward direction, and a compression spring member arranged between the fixed spring receiving member and the movable spring receiving member. In each clamp member, the movable spring receiving member, as moving rearward, comes into contact with a front surface of the movable head member in a manner such that the movable spring receiving member is capable of moving in the vertical direction relative to the front surface.
