ABSTRACT:
An industrial robot hand for material handling. A fixed frame is connected to an arm of an industrial robot. A movable frame having a rectangular plan shape is horizontally movably supported on the fixed frame. Two guide rods are vertically attached to each of the four sides of the movable frame. A tapered guide extends downwardly from each of the guide rods. Sandwiching plates are provided on two opposite sides of the movable frame. Each sandwiching plate is pivotally attached to the movable frame by a horizontal axis at the central portion of the sandwiching plate. Engaging members project inwardly from the lower inner surface of the sandwiching plates to hold the material to be handled. Rollers and roller guides restrict the movement of the movable frame on the fixed frame. A driving mechanism pivots the sandwiching plates to bring the engaging members into engagement with the material.
