Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to cold rolling lines, steel strip shearing lines,
The present invention relates to a metal strip winding device suitable for use in steel strip rewinding lines and the like.

[Prior Art] In steel strip shearing lines and the like, bridle rolls are provided before and after the looper in order to release the tension acting on the steel strip. The frictional force that the bridle roll applies to the steel strip increases as the winding contact angle of the steel strip to the bridle roll increases. Therefore, in some cases, the center axes of a plurality of bridle rolls are arranged at different levels from each other, and the contact angle is set to about 200 degrees. However, when trying to thread a steel strip through bridle rolls with different levels, the rigidity of the steel strip impairs the threading workability. Therefore, a winding device consisting of a fixed bridle roll 1 and an elevating bridle roll 2 as shown in FIG. 7 is used. This winding device disposes an elevating bridle roll 2 immediately in front of a winding reel 3, moves the bearing box of the bridle roll 2 with respect to the frame, and sets the bridle roll 2 to a retracted position shown by a two-dot chain line. The steel strip 4 is set in the steel strip grip portion of the take-up reel 3 under the conditions of Thus, tension is applied to the steel strip 4. θ1 and θ2 indicate contact angles.

On the other hand, in conventional winding devices, the winding reel 3
The winding of the steel strip 4 is carried out as indicated by the one-dot chain line in FIG. 6, or as a trade-in as indicated by the two-dot chain line in FIG. Therefore, the conventional winding device is equipped with a guide table 6 that is moved up and down by a cylinder device 5, and is configured to guide the leading end of the steel strip 4 to the clip portion of the winding reel 3 corresponding to take-up or trade-in. In addition, the guide table 6 can be set to the take-up position shown by the one-dot chain line in FIG. 6 or the trade-in position shown by the two-dot chain line in FIG.
