の全長が長くなる問題があつた。 As shown in Japanese Unexamined Patent Publication No. 55-148164, the air cylinder drive mechanism is rotatably attached to a side plate provided at the end of the winding shaft, and the air cylinder piston is driven by compressed air. It is always returned to its original position by the reaction force of the compression spring provided between the side plate and the winding shaft. The winding outer diameter of the winding shaft changes depending on the amount of winding of the strip, but rollers are provided in contact with the outer periphery of the winding shaft, and the rollers transmit movement to a pin directly connected to the central shaft. One end of the piston of the air cylinder is rotatably connected to an arm of a one-way clutch fitted to the end of a winding shaft passing through the side plate, and the winding shaft is rotated by driving the air cylinder. A U-ring is fixed to the winding shaft adjacent to the one-way clutch via the side plate, and a pin is inserted between the widths of this U-ring. Movement is restricted between the stoppers. Therefore, although the U-ring rotates together with the winding shaft, since it abuts against the pin, the rotation angle is limited by the distance between the two stoppers. In other words, by limiting the rotation angle in accordance with changes in the outer diameter of the strip, the length of the strip to be wound is always limited to a constant value. However, it is necessary to provide a retaining mechanism for the rollers separately from the side frame.
There is a problem in that the number of parts such as rings increases, and the tip of the engaging pin swings as the air cylinder strokes, resulting in an increase in the overall length of the drive mechanism such as the air cylinder.

Thereafter, it is constantly returned to its original position by the tensile force of a tension spring 13 provided between the winding shaft 2 and the side frame 8. A roller 10 is in contact with the outer periphery of the winding shaft 2, and a detection body 6 is directly connected to the center of the shaft. Moves according to changes in outer diameter R up to 1 . The tip of the detection body 6 slidably passes through the side frame 8 and moves while being guided by the side surface B (arc shape) of a pin receiver 7 provided as a through hole in the side frame 8. The middle portion of the detection body 6 is supported by a support lever 11 rotatably supported by the side frame 8, and is supported by a tension spring 9 provided between the support lever 11 and the side frame 8.
