Claims

[Scope of Claim for Utility Model Registration] (1) The tip of a workpiece receiving shoe is placed between two rolls disposed above and below, and a workpiece stopper is provided opposite to the shoe and can be approached and separated from the shoe. A gap is provided along the circumferential surface of the lower roll between the and the tip of the shoe, into which two workpieces fit, and when the workpieces are fitted into the gap, the center of the workpiece that comes into contact with the work stopper is placed at the top of the lower roll. The pusher is set to be more biased toward the workpiece stopper side, and a locking part in which the workpiece fits is provided between the top of the lower roll and the tip of the shoe, and a pusher is moved on the shoe to push the workpiece into the gap. A device for carrying in and discharging an annular workpiece, characterized in that the workpiece stopper is connected to a drive machine that moves the workpiece toward and away from the shoe. (2) Provide a position detector that detects changes in the position of the workpiece stopper when the workpiece is fitted into the gap,
2. The annular workpiece loading/unloading device according to claim 1, wherein the detection signal of the detector is used as a machine abnormality signal.
