<p>PURPOSE:To prevent misplacement of a work in reversing in a circular work reversing device of the optical element machining device in the caption by providing a pair of holding claws for holding the work on a reversing frame so that the work which is carried in is adsorbed by an adsorbing device, moved to the claw position, held by the claws and reversed. CONSTITUTION:When a circular work 1 which is carried in by a conveyer 2 is stopped at the center of a reversing device, a work adsorbing pad 15 is lowered by cylinders 17 and 20 so as to adsorb the work 1. Then, the work 1 is raised to the center height of a flat claw 11 and a V-shaped claw 12 by the cylinder 20, and both the claws 11 and 12 are closed by cylinders 13 and 13' so as to hold the work 1. then, adsorption is released and the adsorption pad 15 is retrieved and then, a reversing frame 9 is reversed. Then, the work is held by the adsorption pad 15 again to be return to the conveyer 2.</p> |
