PURPOSE:To enable an apparatus to hold a work in a different size to be immediately given a rotary input, by providing a pair of endless belts to be approachably and separably arranged in the point end of an arm and moving opposed belt sides to be transferred mutually in a reverse direction. CONSTITUTION:A work hand apparatus has a pair of supporting frames 2a, 2b, opened and closed by a frame opening and closing mechanism 2, in the point end of a robot arm 1. The both supporting frames 2a, 2b provide endless belts 3a, 3b wound and tensely provided between pulleys 32, 33. After the apparatus holds a work between opposed belt sides 30a, 30b, if a motor 42 is actuated, the apparatus, rotating the wheels 32 in the same direction, moves the opposed sides 30a, 30b of the endless belts 3a, 3b to be transferred mutually in a reverse direction. In this way, the work is given a rotary input. |
