Description

BAND SEPARATION REMOVAL DEVICE OF COIL

The present invention relates to a device for separating and removing a wrapping band of a coil, and more particularly, when a strip is mailed for processing of a hot rolled stainless coil, that is, rewinding, side trimming, annealing, grinding, and cold rolling. The present invention relates to a wrapping band separating and removing device of a coil used to recover a wrapping band for preventing loosening of a coil bound to an outer winding of the coil.

In general, when the strip is mailed, as shown in FIG. 1, the outer peripheral portion of the coil 24 is pressed with the hold down roll 27 to prevent the coil 24 from loosening when the wrapping band 28 is cut. The cutting band of the tip portion (A) of the cutting edge) is cut, and the band 28 ends at the end of the deflecting pinch roll 30 and the leveler rolls 31 and 32 with the band 28 overlapping the strip B. When passing through, the operator directly recovers the band 28. At this time, since the length of the band is too long to be processed, the center portion of the band is folded once and then put into a scrap box.

In addition, since stainless steel is several times more expensive than ordinary carbon steel, reducing defects or scrap generated in each production process is effective in reducing costs and improving productivity, but conventional techniques do not solve these problems.

That is, in the related art, since the outer winding portion of the coil 24 does not come into close contact with the center of the coil when the band 28 is cut, a flaw is formed in one portion of the outer winding portion of the coil 24 by the knife 35, and the strip ( B) The deflect pinch roll 30 and the leveler roll 31 and 32 pass between the deflect pinch rolls 30 and the leveler rolls 31 and 32 with the band 28 superimposed thereon. The replacement cycle is shortened and repair costs are increased.

In addition, if the band marks remain vividly as long as the band length on the surface of the strip (B), the marks remain frequently, and since the remaining portions have to be scraped, the error rate is lowered, which leads to an increase in cost and a decrease in production. There was a problem that a safety accident occurred due to the sharp part of the band during recovery.

Therefore, the present invention has been proposed to solve the above problems, and an object of the present invention is to automatically separate the waste wrapping bands from the strips and to recover them when the strip is mailed, and to recover the coils when cutting the wrapping bands. The present invention provides a coil band removing device for close contact with a center.
