Claims

[Scope of utility model registration request]

A swing arm with a workpiece gripping claw at the lower end that can be opened and closed is rotatably supported at the tip of the swing arm, and this swing arm is always maintained in a constant posture to move in an arc between the carry-in position and the carry-out position. At the position where the reciprocating swing motion is made along the locus, the crank mechanism converts it into a constant reciprocating motion via the rack and pinion, and the swing arm and swing arm are transported to the positions corresponding to the top dead center and bottom dead center of the Kuralev mechanism. , a rotating arm drive device consisting of a rotary motor that stops after one rotation of the crank is provided, with the crank mechanism set at a point other than the top dead center and bottom dead center as the home position, corresponding to the input position and the unloading position, and The opening/closing operation is achieved by installing a cam coaxially with the crank mechanism, and the rotation of this cam displaces the cam follower near the top dead center and bottom dead center of the crank mechanism, and the displacement of the cam follower is transferred to the top of the swinger via a link mechanism. A swing arm type loading/unloading device characterized by having a mechanism that opens and closes by transmitting information to the gripping claws of the swing arm.
