In the present invention, the cold rolled product produced at the final output stage of the cold rolling process (annealing, peaking, plating) of the steel mill, the paper thread is automatically inserted in order to prevent the occurrence of end mark defects occurring at the innermost side of the coil to be wound. In particular, the present invention relates to a device for minimizing the amount of streaks generated in the width direction of the coil, which is the final product, and automatically inserting a paper seal in a continuous line, and a method of operating the same. will be.

Cold rolled steel sheets produced in steel mills are finally wound on coils using a winding machine. Due to the thickness of the steel sheets, end mark marks or bend marks due to the thickness of the first coil steel sheets are wound on the coil steel sheets wound after the second one. There is a defect that occurs.

Referring to FIG. 1, which shows an end mark occurrence situation occurring in an exit tension reel of a steel mill cold rolling process, the tip portion of the strip 101 is cut in a state where the strip 101 is cut at the strip cutting portion of the cold rolling line. Since it forms a right angle, the strip 101 is wound on the tension reel 104 to be wound in the form of a coil 102.

In the above process, the first winding end of the strip 101 presses the surface of the next winding strip 101 to generate an end mark A having an uneven shape.

In more detail, the present invention as described above, by inserting the paper chamber 202 into the tension reel (104) to prevent the coil defects called end marks that occur when the coil 102 is wound, It is to reduce the step height of the top portion of the strip 101 to prevent the end mark defect.                     

The paper seal 202 is wound up by winding the paper seal 202 up to the outer diameter 2/3 of the tension reel 104 so that the top portion of the strip 101 is wound from the portion where the paper seal 202 is not wound. ) To form a gap between the strip 101 and the strip 101 to reduce the step difference in the top portion of the strip 101.

5 to 7 show the interlocked configuration and operation relationship of the paper mark automatic insertion device for preventing the end mark according to the present invention in detail, and the cross-sectional structure of the paper chamber 202 is shown in FIGS. It is shown in detail so as to know the process of cutting, feeding and winding.

With reference to the attached Figures 11 and 12 described in more detail the paper mark automatic insertion device for preventing the end mark according to the present invention, after the coil 102 wound from the tension reel 104 is drawn out, the re-winding operation For this purpose, preparation, which is a rewinding operation of the tension reel 104, is performed.

After the preparation process by the winding preparation operation is completed, the apparatus according to the present invention receives the information of the next winding material from the host computer by the rewind preparation end signal, and winds up the material having a thickness of 1.0 mm or more, which is the next winding material. The work is wound around the tension reel 104 where the winding preparation is completed, and the paper seal 202 to the outer diameter 2/3 of the tension reel 104.

By the above operation, first, the upper feeding roll 307 is closed in order to wind the paper chamber 202 on the tension reel 104, and in the next operation, the tension reel 104 is closed. At the same time that the driving motor 318 for rotating the lower feeding roll 308 is driven in order to transfer the driving process, the tension reel 104 is also rotated together.

The length that the paper chamber 202 is unwound and supplied is calculated by the PLG 501 and supplies 2/3 of the outer diameter of the tension reel 104.

In general, the standard of the tension reel 104 used to wind the cold rolled coil is, for example, 1900 mm, so that 1260 mm, which is two-thirds of the 1900 mm, is calculated or counted and the knife 324 of the cutter 401 It is cut by the process and is automatically supplied to the tension reel (104).

When the above process proceeds, the tension reel 104 and the upper and lower feeding rolls 307 and 308 stop and the paper chamber 202 is prepared to prevent the end mark, and the atmosphere for winding the strip 101 is completed. It becomes a state.

When the strip 101 as a product is wound or wound by a predetermined length on the tension reel 104 in the above standby state, and when the strip 01 of the predetermined length is wound, the strip 101 is cut by a flying share. The strip 101 is supplied and wound up to the tension reel 104 in the next standby state.

The attached photo sensor 502 of Figure 7 detects the speed of the strip 101 is supplied for winding, and considering the rotational speed of the tension reel 104, the cut top portion of the strip 101 is tension reel The paper mark 202 is wound around the remaining 1/3 of the paper thread 202, which is not wound, so that the end mark or the secondary mark is applied to the strip 101 by the play between the strip 101 and the paper thread 202. Prevent step marks from forming.

In other words, when the outer diameter of the tension reel 104 is 1900 mm, and the distance between the strip 101 top detecting sensor and the tension reel 104 is 1900 mm, when the top part of the strip 101 passes through the sensor, Since the top portion of the strip 101 enters a space where the tension chamber 104 is prepared by one rotation and the paper chamber 202 is not wound, that is, a third point, there is a gap between the strip 101 and the paper chamber 202. It is formed to reduce the step difference of the top portion of the strip 101, and prevents the end mark or the secondary step mark due to the step of the coil 102 wound on the tension reel (104).

The present invention has the effect of not forming an end mark on the coil wound by winding the paper thread formed in a diagonal shape about 2/3 of the outer diameter of the tension reel and start the cut saw portion of the strip to the remaining portion.

In addition, since the paper thread is automatically wound on the tension reel, there is an effect of working quickly and improving the quality of the product.
