PCT No. PCT/JP81/00269 Sec. 371 Date Jun. 4, 1982 Sec. 102(e) Date Jun. 4, 1982 PCT Filed Oct. 7, 1981 PCT Pub. No. WO82/01157 PCT Pub. Date Apr. 15, 1982.A double hand applicable to an industrial robot comprises two hand units (2, 3) comprising at least two pairs, one each, of fingers (2-1 and 2-2, 3-1 and 3-2) and plate members (2-3, 3-3) of a pressing unit (4) disposed in parallel along the center axis of the fingers. The hand units (2, 3) are connected through a pressing mechanism (4) to constitute a double hand in a manner that the respective gripping center axis of the two hand units are in alignment, the respective plate members (2-3, 3-3) of the pressing unit are disposed opposite to each other and the opening sides of the respective pairs of fingers of the two hand units are directed in opposite directions to each other. An opening (6) for allowing a workpiece to penetrate through the plate members is provided for each of the plate members (2-3, 3-3) of the pressing unit attached to the hand units (2, 3 ) respectively coaxially with the gripping center axis so that both hand units (2, 3) are allowed to move freely relative to the workpiece gripped by the hand units (2, 3) along the gripping center axis. |
