Scraper stripping device on strip surface

The present invention relates to a device for removing bark pieces attached to a surface of a strip, and more particularly to a device for removing bark pieces on a surface of a strip which is more effective for removing bark pieces that have not been removed from the surface of the strip by bellows- will be.

In general, when a strip, particularly a thin stainless steel sheet, is coiled, a sheet of paper, which is a thin paper, is inserted between the strips, which is to prevent the surface of the strip from contacting each other and causing scratches and the like.

The separator is detached from the surface of the strip as required, for example, at the inlet side of the alkali degreasing facility (a facility for removing the oil such as rolling oil adhered to the strip) before the strip enters the annealing furnace, Fig. 1 schematically shows the separating method.

That is, the paper prills 120 and the paper winder 130 are mounted on the inlet side of the degreasing apparatus 110, and the strips 141 and the separators 142 are wound on the paper prills 120 The separator 142 separated from the strip 141 while the strip 141 is moved to the degreasing apparatus 110 side by operating the paper prill 120 in this state, 130 in the form of a coil.

However, when separating the separator 142 from the strip 141, the separator 144 is still present on the surface of the strip 141, which is torn off from the separator 142 by crimping or the like, It is necessary to manually remove the separator 144 by an operator at the entrance of the degreasing facility 110 after the operation of the facility has been stopped in order to remove the separator 144, The strip 141 is passed through the degreasing unit 110 to remove the degreasing piece 144 from the strip 141 together with the rolling oil by the alkali solution injected from the degreasing unit 110.

However, in the above-described conventional method, when the separator 144 is manually removed from the entrance of the degreasing facility 110 after stopping the operation of the facility, the productivity is deteriorated due to the operation stoppage of the facility, When the degreasing apparatus 110 is passed through without removing the separator 144, the separator 144 separated from the strip 141 may cause clogging of the pump and the filter of the degreasing apparatus But also has a problem of causing the alkaline solution in the alkali solution tank to be contaminated to lower the life of the alkaline solution.

The present invention is intended to solve such a conventional problem, and it is possible to automatically remove the slip pieces not separated from the strip surface on-line before entering the degreasing facility, The present invention has been made in view of the above problems.
