PURPOSE:To eliminate controls thus to simplify the control system, smooth the operation and to prevent erroneous operation by engaging a horizontal moving mechanism and a turn drive mechanism through a cam follower then interlocking the turning of arm and horizontal motion. CONSTITUTION:Upon coming of a pallet mounting a work to predetermined position, hydraulic pressure is applied onto ports (a), (d) to move a cylinder 315 toward the end of rod 311 to rotate an arm 330 in accordance to the rotation of pinion 327 caused by lowering of piston 322. Upon turning of arm 330 by 90 deg., the hand will be at such position as to catch the work W and upon reduction of pressure in port (e) to apply onto a port (f'), the arm will move and the hand will catch the work W. While upon application of pressure onto the ports (b), (c), only the rod 321 will lift and upon rotation of arm 330 counterclockwise to the vertical position, groove 326 and cam follower 314 are engaged and the cylinder 315 will push the arm forward of conveyor thus to pass the work W to holding section 724. |
