Claims

[Scope of utility model registration request]

A stopper cylinder whose upper end portion protrudes upward from between the pair of belt conveyors and can freely come into contact with the front end of the work in the conveyance direction, which is conveyed with both sides placed on the pair of belt conveyors, at a predetermined position; A clamp cylinder is provided behind the stopper cylinder and below the belt conveyor, and the front end of the rod that extends and contracts in the work conveyance direction of the clamp cylinder is provided with a clamp member located below the belt conveyor. The clamp member is rotatably supported from a horizontal position buried in the belt conveyor to an upright position protruding above the belt conveyor, and an elastic member is provided for biasing the clamp member in the upright direction, and the rod of the clamp cylinder is in the shortest position. a stopper that presses the clamp member downwards on the belt conveyor against the biasing force of the elastic member to hold it in a horizontal position; With the front end in contact with the stopper, the rod is stroked to a position where the clamp member, which stands upright after being released from the stopper, contacts the rear end of the workpiece, and presses the rear end of the workpiece with a predetermined pressure. A clamping device for a workpiece, comprising a clamping position control means for clamping the workpiece.
