摘要

PURPOSE: A rotary vacuum-griper is provided to make rotation of a vacuum cup easy by balancing the rotation with a simpler configuration. CONSTITUTION: A rotary vacuum-griper(10) comprises a fixed body(11), a connection part(17), a vacuum cup(13), and an elastic balancing member. The fixed body comprises a ball joint(12) and a path(14) with open top and bottom. The connection part fastens an upper superstructure(18) and a lower structure(19) to a ball part(12b). The vacuum cup comprises a pad(20) which is being fixed to the connection part with internal space connected to the lower side of a through hole(16). The elastic balancing member comprises either a balance spring(25) or a balancing bellows pipe(26).
