Description

  The present invention provides a slit material winding device for winding a slit material obtained by dividing a metal strip into a coil shape, and a slit material obtained by winding a slit material from a metal coil wound with a metal strip. The present invention relates to a slitter line for obtaining a coil.

  In a conventional slitter line, a metal strip S supplied from an uncoiler to which a metal coil is attached is divided in the width direction by a slitter to form a plurality of slit members, which are wound by a slit member winding device. It was.

  In addition, the conventional slit material winding device is located on the upstream side and the downstream side of the separator disk in the conveying direction of the separator disk and the separator disk positioned between the plurality of slit materials. A drive roll such as a pinch roll or a bridle that transports in the longitudinal direction and a recoiler that winds the slit material on the most downstream side in the transport direction of the slit material.

However, when the tensile strength of the metal strip is higher than the tensile strength (270 MPa (28 kg / mm ² )) of a normal steel plate, such as high-tensile steel (tensile strength: 440 MPa (45 kg / mm ² )), the driving is performed. Since the slit material that has obtained the driving force from the roll generates a large drag against the driving force due to its strong tensile strength, the slit material will swing more than expected in the front and back direction and the width direction (hereinafter referred to as the above-mentioned “ The “sliding movement of the slit material” is called “fluttering of the slit material”). And if the amount of flutter of the slit material exceeds the radius of the separator disk, the slit material rides on the separator disk, and the width edge of the slit material makes strong contact with the separator disk.

  (1) In the slit material winding device 2 of the present embodiment, a flutter prevention roll 9 is disposed in the vicinity of the upstream side of the separator disk 16. Thereby, even if the tensile strength of the metal strip B is high, the slit material S can be prevented from riding on the separator disk 16. As a result, it is possible to set the driving force applied to the slit material S from the driving rolls provided on the pinch rolls 6 </ b> A to 6 </ b> E to be higher than that in the past, so that the winding speed when applying a low driving force ( 14t / h), the winding speed of the slit material S can be greatly increased (24 t / h (about 1.7 times) in this embodiment).

  (2) Further, in the slit material winding device 2 of the present embodiment, the two anti-fluttering rolls 9 are positioned so as to face both the front surface side and the back surface side of the slit material S through the slit material S. To do. Thereby, since the fluttering of the slit material S can be pressed from both the front surface side and the back surface side of the slit material S, the winding speed of the slit material S can be further increased.

  (3) In addition, in the winding device 2 for the slit material of the present embodiment, when the separator roll 15 is positioned as a driving roll or a driven roll on one of the front surface side or the back surface side of the slit material S, the anti-fluttering roll 9 is At least the other side of the front side or the back side of the slit material S may be positioned. Thereby, the separator roll 15 suppresses the slit material S from one of the front surface side or the back surface side of the slit material S, and the flutter prevention roll 9 suppresses the slit material S from the other of the front surface side or the back surface side of the slit material S. Therefore, fluttering of the slit material S can be effectively prevented while minimizing the number of rolls that may form defects such as scratches on the front and back of the slit material S.

  (4) Moreover, in the winding device 2 of the slit material of this embodiment, it is preferable that the holder 17 hold | maintains the flutter prevention roll 9 so that attachment or detachment is possible. Thereby, when the metal steel plate used as the material of the slit material S is an ordinary steel plate having a weaker tensile strength than the high-strength steel, the anti-flutter roll 9 is removed, and the anti-flutter roll 9 abuts against the slit material S. The possibility that defects such as scratches are generated on the surface of the slit material S can be completely eliminated.

  (5) Moreover, in the winding device 2 of the slit material of this embodiment, it is preferable that the anti-fluttering roll 9 is a driven roll having a diameter of 0.1 m or less in which a buffer rubber is attached to the roll surface.

The possibility can be reduced.

  Further, in the slit material winding device 2 of the present embodiment, the flutter prevention roll 9 is preferably positioned upstream of the separator disk 16 by 0.3 m or less. As a result, even when the slit material S fluctuates greatly between the anti-fluttering roll 9 and the separator disk 16, the slit material S has only a slight gap between the anti-fluttering roll 9 and the separator disk 16. Riding on the separator disk 16 can be effectively prevented.

  (6) Moreover, in the winding apparatus 2 of the slit material of this embodiment, it is preferable that the metal strip B is a high-tensile steel plate formed in a strip shape. Thereby, even if the high-strength steel plate having a strong tensile strength is the metal strip B, the slit material S can be prevented from riding on the separator disk 16.

  (7) Moreover, in the winding device 2 of the slit material of this embodiment, it is preferable that the holder 17 holds the anti-flutter roll 9 so as to be movable by a predetermined amount in the front and back direction of the slit material S. Thereby, even when the slit material S flutters in the front and back direction, the flutter prevention roll 9 moves in the front and back direction of the slit material S corresponding to the flutter, so that the surface or the like of the slit material S is damaged. The possibility of the occurrence of defects can be reduced.

  (8) Further, in the slit material winding device 2 of the present embodiment, it is preferable that the holder 17 holds the flutter prevention roll 9 so as to be movable by a predetermined amount in the transport direction FD of the slit material S. . Thereby, even when the slit material S flutters in the transport direction FD, the flutter prevention roll 9 moves in the transport direction FD of the slit material S corresponding to the flutter, so that the surface of the slit material S or the like The possibility that defects such as scratches will occur can be reduced.

  (9) Moreover, the winding device 2 for the slit material of the present embodiment further includes an urging unit 20 that urges the anti-fluttering roll 9 in the direction opposite to the movement direction of the anti-fluttering roll 9. preferable. Thereby, when the flutter prevention roll 9 moves corresponding to the flutter of the slit material S, the flutter prevention roll 9 itself can be prevented from fluttering.

  (10) Further, the slitter line 1 of the present embodiment includes the above-described slit material winding device 2. Thereby, even if it is a case where the tensile strength of the metal strip B is high, there exists an effect of said (1)-(9) that the slit material S can be prevented from riding on the separator disk 16, etc. it can.

  That is, according to the winding device 2 of the slit material of the present embodiment, it is possible to prevent the slit material S from riding on the separator disk 16 even when the tensile strength of the metal strip B is high. Play.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.
