Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a sleeve from being attached to a drum shaft of a winder used for winding a steel strip coil or the like.

[0002]

2. Description of the Related Art When a steel strip is wound into a coil, the steel strip is wound around a drum shaft equipped with an expansion / contraction mechanism. A push defect occurs due to the end of the member to be pressed. Therefore, in order to prevent this or to cope with a change in the inner diameter of the steel strip coil, a rubber sleeve corresponding to the inner diameter of the steel strip coil is mounted on the expanding and contracting drum shaft. However, when the wound steel strip coil is pulled out from the drum shaft, the mounted sleeve comes out together with the steel strip coil. Therefore, for example, as shown in Japanese Utility Model Publication 5-19131, Sleeve stoppers have been proposed. The sleeve stopper of this winder is shown in FIG. 4. A sleeve 61 is attached to the expanding / contracting drum shaft 60, and a cam 63 is provided at the end of the expanding / contracting wedge 62 of the drum shaft 60. A driven stopper 64 is attached to the tip of the drum shaft 60 to prevent the sleeve from coming off while the stopper 64 is in operation when the steel strip coil is pulled out. In addition, 65 is a segment, 66 is a nut, 67 is a roller, 68 is a spring, and 69, 70

However, in the sleeve stopper of the winder described in the above publication, the height of the stopper 64 is set in order to prevent the sleeve 61 from being dragged by the steel strip coil and attempting to come out. It is necessary to raise it to a certain degree, and in this case, there is a problem that when the thickness of the sleeve 61 is thin, it becomes an obstacle when extracting the steel strip coil. Furthermore, since the conventional sleeve 61 has a cylindrical shape with no change in thickness, it is difficult to mount the sleeve 61. Especially, in the case of a thin sleeve, it is difficult to perform the work without deforming the circular shape, and automation is also difficult. There was a problem. The present invention has been made in view of such circumstances, and the sleeve can be easily attached and detached and does not come off when the steel strip coil is pulled out. The purpose is to provide a stop device.
