Abstract
A disk ( ) is horizontally rotated a half-turn by a motor ( ) in a rotational direction and, then, is rotated a half-turn in an opposite rotational direction. Two servomotors ( ) are symmetrically disposed, on an upper surface of the disk ( ), with respect to a rotating shaft of the disk ( ). Driving shafts ( ), driven by the two servomotors ( ), downwardly extend through the disk ( ), and move hanging members (K, M), respectively, in upward-and-downward directions. Two hanging members (K, M) are provided, at their lower ends, with clampers ( ), respectively. The clampers ( ) are each provided, at their bottom surfaces, with a suction pad ( ), and are provided, at their upper surfaces, with pneumatic cylinders ( ). The pressure of the compressed air supplied to the pneumatic cylinder is adjusted by a pressure regulating device ( ).
