The present invention relates to a device for removing the slip paper flowing into the degreasing tank, and more particularly, to prevent friction defects caused by friction between the coil and the coil during winding the rolled coil in the rolling process. It relates to a device for removing the positioning sheet before the degreasing process.

In general, in the rolling process, the steel sheet is pressed and processed, and the length of the steel sheet is lengthened by the number of rolling and the reduction ratio. Therefore, in the cold rolling process, the steel sheet is wound in the form of a coil to be rolled or stored.

In the process of rolling or storing the steel sheet in the form of a coil, when the coil is unwound or the coil is wound, friction is generated between the rolled sheet, which causes damage to the surface of the sheet.                         

In this case, if the rolled sheet material is an intermediate product, the friction groove on the surface can be removed in the post-rolling process, but in the case of the coil of the finished product that does not require the post-rolling process, the product will be seriously damaged.

Therefore, in such a case, in the process of winding the friction flaw generated by the friction between the surface of the sheet with a coil, a method of preventing frictional flaw due to friction by preventing direct friction between the sheet between the rolled sheet and the sheet is used.

These sheets should be removed prior to the degreasing process to remove the rolled oil or foreign matter on the plate, which is an annealing or annealing process.

In general, the rolled sheet is an annealing process as a means to relieve the stress during the rolling process, and is a degreasing process that removes oil or foreign matter that volatilizes or oxidizes at high temperature during annealing to adversely affect the sheet during annealing. The work is done.

Therefore, decoiled annealing is also performed on the coil with a slip sheet, and the slip sheet is wound and removed in the process of releasing the rolled coil for degreasing.

However, the process of removing the slip sheet is to remove only the sheet attached to the rolled sheet by using a roll to remove the sheet, and the sheet is broken according to the change of tension between the rolled sheet and the sheet, and the tension of the roll depends on the coil unwinding speed. Some attachment occurs.

In such a case, it is necessary to remove the sheet of paper before the sheet is loaded into the degreasing process, and the method of removing the previously broken sheet of paper before the degreasing process is observed by the naked eye and the broken sheet of paper with the sheet is degreased. If incoming, it was removed by hand.

However, this method has a very fast moving speed of 14m / min, and it is difficult for the worker to remove the kanji by hand while the thickness is about 1mm and there is a risk of safety accident.

If it is not possible to remove the sheet of paper (A) due to this difficulty in the degreasing process as shown in Figure 1, the sheet of paper (A) is dissolved in the alkaline solution to contaminate the alkaline solution storage tank 120 and pump the alkaline solution (130) When spraying to the coil 100 by using a) to close the injection nozzle, or to contaminate the coil and the contaminated coil surface when the coil passes through the squeeze roll 121, contaminants are pressed to the surface causing surface defects, There was a problem that the alkaline solution contaminated by the ice sheets had to be replaced.

Accordingly, a technical problem to be solved by the present invention is to provide an apparatus for removing sebum so that the sebum is not introduced into the alkaline solution tank by removing the sebum attached to the coil before the degreasing process so as to solve the above-described problem.

The present invention for achieving the above-described technical problem is coupled to the frame rotatable and the inner space is formed inside the cover to cover the coil to proceed, and the rotating roll fixed to the cover and a plurality of air flow holes in the belt Is formed in the rotating belt, coupled to the cover and the air blocking plate to prevent the air flow by blocking between the upper belt and the lower belt of the rotating belt, and is coupled in communication with the lower space between the air blocking plate and the lower belt Air intake means, the air discharge means coupled to the upper space portion between the air blocking plate and the upper belt, the discharge port formed in the upper cover, the lifting and lowering means coupled to the frame and the sensing bar is coupled to the end And a detection sensor for transmitting a signal by detecting a rising and falling of the detection bar, and a rotation belt and air suction by receiving a signal from the detection sensor. It consists of a controller that controls the operation of the inlet means and the air outlet means.

Hereinafter will be described in detail with the drawings according to an embodiment of the present invention.
