Abstract
A new parts handling apparatus is provided which can shorten the index time and increase working ability without increasing the number of components and can restrict the rise of manufacturing cost. X driving member to be moved rightward and leftward in correlation to the rotation of a ball screw by a servomotor is provided with a pair of right and left movable members mounted movably in the Z direction. Two contact hands are attached to each movable member through aligning mechanisms respectively. Each movable member is provided with a Z driving member mounted slidably in the X direction. The Z driving member is engaged with a ball screw , and the ball screw is connected to a servomotor . When the ball screw is rotated by the servomotor , the Z driving member moves vertically in the figure, thereby also moving the movable member vertically.
