PURPOSE:To certainly recover a dropping object without providing a recovering container at a dropping point by providing a hopper for receiving a dropping object on an output shaft of an oscillating cylinder of a receiving device for the dropping object such as a comparatively big chip and the like. CONSTITUTION:When fluid pressure is supplied from an intake port 73 of a cylinder 11, a reed screw bush 21 united in one body with a piston 19 moves along a pin 27 and a reed screw 25 is rotated within a predetermined stroke. Rotation of the reed screw 25 is transmitted to an output shaft 43 to rotate a hopper arm 41. With this rotation, a hopper 45 is rotated to move from a leaving position O1 to a receiving position O2 and is stopped at a position right under a core 3. When the core 3 is dropped, it drops into a hopper 45' and is received by means of a receiving board 49'. When the fluid pressure is supplied from an intake port of the underside of the cylinder 11, the hopper is rotated in the reverse direction to return to the former position and drops the core 3. |
