Description

  The present invention relates to a side surface irregularity correction device for correcting side surface unevenness of a metal strip coil such as a steel strip coil manufactured by hot rolling, for example.

  For example, a hot rolled steel strip manufactured in a hot rolling line of a steel mill is wound up in a roll shape by a winder. In this specification, the steel strip wound up in a roll shape is referred to as a “steel strip coil”. Since the starting end portion of the steel strip is not fixed until it reaches the winder, the winding of this portion is not stable, and as shown in FIG. An uneven shape (winding deviation) TI may occur. Moreover, since the end portion of the steel strip is wound in an unfixed state, the winding is not stable even in this portion, and the telescope shape irregularity (winding deviation) also occurs in the outer diameter portion of the side surface of the steel strip coil. There is.

  If the irregularities on the side surfaces of these steel strip coils are left unattended, the irregular portions may be bent in the subsequent steps and cause quality defects. For this reason, it is preferable to correct the unevenness and align the side surfaces of the steel strip coil. In the present specification, a state where the axial direction of the metal strip coil is along the vertical direction is referred to as “up end”, and a state where the metal band coil is along the horizontal direction is referred to as “down end”.

  2. Description of the Related Art A correction device that corrects uneven side surfaces of a metal band coil such as a steel band coil is known. Patent Document 1 describes a technique for correcting unevenness of a side surface by pressing a side surface of a metal band coil installed at a down end with a plate. Patent Documents 2 and 3 describe a technique for correcting unevenness of the side surface by applying a load to the side surface of the metal strip coil installed at the up end with a smoothing plate positioned above the side surface.

  Hereinafter, embodiments of the metal band coil side surface unevenness correcting device of the present invention will be described.

  A steel band coil side surface irregularity correction device 100 (hereinafter simply referred to as “correction device”), which is an example of a metal band coil, will be described with reference to FIGS. With reference to FIG. 1, the correction device 100 of the present embodiment includes mounting members 10 </ b> A and 10 </ b> B, a first support member 20, and a second support member 30.

  The mounting member 10A and the mounting member 10B are rectangular parallelepiped members of the same size for mounting the steel strip coil on the down end, and are positioned at a predetermined interval so that their longitudinal directions are parallel to each other. Referring also to FIG. 2, the mounting surface 12A and the mounting surface 12B have the same vertical height, and the mounting members 10A and 10B are positioned so that both ends in the longitudinal direction are aligned. 2 and 4, steel strip coil M is mounted on the mounting members 10A and 10B on the down end so that the axial direction thereof is parallel to the longitudinal direction of mounting members 10A and 10B. . Therefore, although the mounting surfaces 12A and 12B support the steel strip coil M at their end sides, the steel strip coil M does not contact the entire surface.

  1 and 4, the second support member 30 is a U-shaped member having second support surfaces 32A, 32B, and 32C that can support the outer diameter portion of one side surface of the steel strip coil M. is there. The second support surfaces 32A and 32B are perpendicular to the placement surfaces 12A and 12B, respectively. The second support surfaces 32A, 32B, and 32C form the same surface. In this embodiment, the 2nd support member 30 and mounting member 10A, 10B are integrated, and it is a L-shaped member by side view.

  1 and 2, first support member 20 has a first support surface 22 that can support an inner diameter portion of one side surface of steel strip coil M. The first support member 20 is a substantially rectangular parallelepiped member, and only a portion of the first support surface 22 protrudes slightly. The first support member 20 is located in a space surrounded by the second support member 30.

  The first support member 20 has a shaft hole 26 (see FIG. 2) at the lower portion in the vertical direction, and the second support member 30 has shaft holes 38A and 38B at the lower portion in the vertical direction. The rotating shaft 42 passes through these shaft holes 38A, 26, 28B and the base protrusion 40. Therefore, the first support member 20 and the second support member 20 can rotate around the rotation shaft 42.

  Next, a connection mechanism that connects the first support member 20 and the second support member 30 will be described. In the present embodiment, the connection mechanism is inserted into the connection holes 24 provided in the first support member 20, the first connection holes 34 and the second connection holes 36 provided in the second support member 34, and these holes. And a connecting pin (not shown).

  First, referring to FIG. 1 and FIG. 2, the connection hole 24 of the first support member and the first connection hole 34 of the second support member are aligned, and the connection pin is passed through these two holes. In this case, the first support member 20 and the second support member 30 are connected and fixed in a first state in which the first support surface 22 protrudes to the steel strip coil M side from the second support surfaces 32A, 32B, and 32C. The

  Next, referring to FIG. 4, the connection hole 24 of the first support member and the second connection hole 36 of the second support member are aligned, and the connection pin is passed through the two holes. In this case, the first support member 20 and the second support member 30 are connected and fixed in a second state in which the second support surfaces 32A, 32B, and 32C protrude from the first support surface 22 toward the steel strip coil M side. The In other words, the second state is a state in which the first support surface 22 is retracted to a position farther from the steel strip coil M than the second support surfaces 32A, 32B, and 32C in a side view of the correction device 100.

  As described above, since the first support member 20 is rotatable about the rotation shaft 42, the first support member 20 and the first state can be switched between the first state and the second state by the above-described coupling mechanism. The second support member 30 can be connected and fixed.

  The positions of the connecting hole 24, the first connecting hole 34, and the second connecting hole 36 are not limited to the positions shown in FIGS. 1 to 5 as long as the first state and the second state can be realized. In the present embodiment, a configuration in which one connection hole is provided in the first support member 20 and two connection holes are provided in the second support member 30 is shown. However, two connection holes may be provided in the first support member 20 and one connection hole may be provided in the second support member 20 to similarly realize the first state and the second state.

  Next, description of the tilt mechanism that tilts the first support member 20, the second support member 30, and the mounting members 10 </ b> A and 10 </ b> B together with the correction method for unevenness of the side surface of the steel strip coil M will be described. . In the present embodiment, referring to FIG. 2, the tilt mechanism includes a rotating shaft 42 provided on the base projecting portion 40, a rotating shaft 46 provided on the base projecting portion 44, and a back surface (first surface) of the first support member 20. 1, a rotary shaft 52 provided on a surface opposite to the support surface 22, and a cylinder 48 and a piston 50 provided between the rotary shafts 46 and 52.

  The base projecting portion 44 is provided at a position farther from the steel strip coil M than the base projecting portion 40 and at a position lower than the base projecting portion 40 in the vertical direction. As the piston 50 expands and contracts, the cylinder 48 is rotatable about the rotation shaft 46, and the piston 50 is rotatable about the rotation shaft 52.

  First, with reference to FIG. 2 and FIG. 3, when the irregular TI exists in the inner diameter part of the side surface of the steel strip coil M, the correction method will be described. As shown in FIG. 2, the steel strip coil M is mounted on the mounting members 10A and 10B so that the irregular TI on the side protruding from the side surface of the steel strip coil M is on the first support surface 22 side. . And the 1st support member 20 and the 2nd support member 30 are connected and fixed in the 1st state where the 1st support surface 22 protruded to the steel strip coil M side rather than the 2nd support surfaces 32A, 32B, and 32C. In this state, by contracting the piston 50, the first support member 20, the second support member 30, and the placement members 10A and 10B are integrally rotated and inclined about the rotation shaft 42, and the steel strip coil Take M up-end.

  FIG. 3 shows a state after the inclination at an inclination angle of 90 degrees. In this process, the first support surface 22 supports the inner diameter portion of the steel strip coil M, and the uneven TI can be corrected by the weight of the steel strip coil M. At this time, the outer diameter portion of the steel strip coil M is not in contact with the second support surfaces 32A, 32B, 32C. Therefore, since the weight of the steel strip coil M is locally applied to the uneven TI, the unevenness can be corrected. In addition, in the process of the steel strip coil M going from the down end to the up end, the uneven weight TI is gradually subjected to the weight of the steel strip coil M, so that the bending of the uneven TI is also suppressed.

  Next, with reference to FIG. 4 and FIG. 5, when the irregular TO exists in the outer-diameter part of the side surface of the steel strip coil M, the correction method is demonstrated. As shown in FIG. 4, the steel strip coil M is placed on the mounting members 10A and 10B so that the uneven TO on the side protruding from the side surface of the steel strip coil M is on the second support surfaces 32A, 32B, and 32C side. Placed on. Then, the first support member 20 and the second support member 30 are connected and fixed in the second state in which the second support surfaces 32A, 32B, and 32C protrude from the first support surface 22 toward the steel strip coil M side. In this state, by contracting the piston 50, the first support member 20, the second support member 30, and the placement members 10A and 10B are integrally rotated and inclined about the rotation shaft 42, and the steel strip coil Take M up-end.

  FIG. 5 shows a state after an inclination of 90 degrees. In this process, the second support surfaces 32A, 32B, and 32C support the outer diameter portion of the steel strip coil M, and the uneven TO can be corrected by the weight of the steel strip coil M. At this time, the inner diameter portion of the steel strip coil M is not in contact with the first support surface 22. Therefore, since the weight of the steel strip coil M is locally applied to the uneven TO, the unevenness can be corrected. In addition, in the process of the steel strip coil M going from the down end to the up end, the uneven weight TO is gradually subjected to the own weight of the steel strip coil M, so that the uneven TO bending is also suppressed.

  After correcting the unevenness of the side surface, the correction device 100 is returned to the state shown in FIG. 2 or 4, the steel strip coil M is returned to the down end, and then transferred to the next step.

  Thus, the correction apparatus 100 of this embodiment does not need to apply force from the outside to the steel strip coil M, and has a simple device configuration that can correct the unevenness of the side surface by the weight of the steel strip coil M. Moreover, it is possible to individually cope with the irregularity of the inner diameter portion and the irregularity of the outer diameter portion of the side surface of the steel strip coil M.

  The aspect of inclination is not limited to 90 degrees as shown in FIGS. Whether or not the unevenness of the steel strip coil M has been corrected can be determined by observing the side surface of the steel strip coil M on the side where the dead weight is not applied. Therefore, even if the inclination angle is less than 90 degrees, the inclination may be stopped when it is determined that the unevenness has been corrected, and the steel strip coil M may be returned to the down-end state. It is also possible to grasp in advance the relationship between the degree of unevenness and the inclination angle necessary to correct the unevenness, and store the information on the relationship in the storage unit. The degree of unevenness of the steel strip coil to be corrected is measured, the inclination angle corresponding to the measured degree of unevenness is read from the storage unit, and the piston 50 is controlled so as to be the inclination angle.

  When both the inner diameter portion and the outer diameter portion of the side surface of the steel strip coil M are uneven, the unevenness of the inner diameter portion is corrected by the method of FIGS. 2 to 3, and then the correction device 100 is returned to the state of FIG. Thereafter, the unevenness of the outer diameter portion may be corrected by the method shown in FIGS. 4 to 5, or vice versa.

  Further, in any steel strip coil, irregularities do not necessarily protrude from the side surface on the same side. Therefore, a device for reversing the direction of the steel strip coil (for example, a coil turner) is disposed near the straightening device 100, and as shown in FIG. 2 and FIG. Then, the steel strip coil M can be placed on the correction device 100. Alternatively, the correction device having the same configuration as the correction device 100 is arranged so as to be bilaterally symmetric (the first indication surface 20 faces each other) in FIGS. 2 to 5, and the unevenness is corrected using an appropriate correction device. You may do it.

  The dimensions of the straightening device 100 may be appropriately set in consideration of the normal dimensions of the steel strip coil M. For example, referring to FIG. 1, the width of the first support surface 22 can be about 100 cm. Further, the width of the second support member 30 at the position of the second support surface 32C can be set to 250 to 300 cm. The material of each member of the correction device 100 is not particularly limited as long as it has strength to support the steel strip coil M, and iron or the like can be used.

  The present invention can be applied to various metal band coils such as non-ferrous metal coils such as aluminum, titanium, and copper, which can cause unevenness of the side surface, in addition to the steel band coils.

  The metal band coil side irregularity correction apparatus of the present invention can correct the side band irregularity of the metal band coil and has a simple apparatus configuration.
