<p>A vacuum suction hand, and a composite hand mechanism, for attachment to an arm or the like of an industrial robot. In the va cuum suction hand a sponge material (8) is attached to the outer surface of a porous plate (7) which covers vacuum chamber (2), thereby preventing the holes in the porous plate from being closed by a film with which a workpiece is packaged. The composite hand mechanism of the invention has gripping mechanisms (140) in addition to a suction mechanism. The gripping mechanisms have gripping frames (150) whose gripping width and gripping force can be adjusted, and gripping plates (170) which are moveable in the vertical direction. Thus, even if a force in the horizontal direction acts on a workpiece (M), the workpiece can still be safely held.</p> |
