DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding control method and a winding control device for a winding strip for winding a strip having two or more slits.

[0002]

2. Description of the Related Art A strip is slit into two or more strips having a predetermined width, and the side edges of the strip are aligned to be wound on a tension reel. At that time, processing such as shape correction, inspection, and application of rust preventive oil may be performed. 2. Description of the Related Art Conventionally, an EPC (edge position control) device as shown in FIGS. 7 and 8 has been known as a take-up control device that winds up a tension reel while aligning side edges of a band plate. In the slitter line shown in FIG. 7, after the strip 1 is discharged from the payoff reel 7, the strip 1 is fed along the pass line formed by the deflector rolls 8 a and 8 b and the slitter 2. It is slit into two strips 1a and 1b and wound up on a tension reel 61 equipped with an EPC device. In the winding control method using the EPC device, the edge sensor 10 detects the edge positions of the strips 1a and 1b on the entry side of the tension reel 61,
The EPC arithmetic and control unit 9 calculates a meandering amount, which is a deviation from a target position with respect to the detection position of the band plate, and operates the hydraulic cylinder 6c based on the meandering amount to provide a mandrel 6a driven by a drive motor 6b. By moving the tension reel 61 in the axial direction, the side edges of the band plate are aligned, and the tension reel 61 is wound around the tension reel 61.

Japanese Patent Application Laid-Open No. 5-31532 discloses that the amount of tilt of a snubber roll that contacts the outer peripheral surface of a coil is controlled based on a deviation from a target position with respect to a detected position of a band plate, so that a side end of the coil is controlled. A method for controlling the winding of a strip that aligns the strips is disclosed. The snubber roll is mounted on an integrated shaft, and the center of the shaft is supported via a pin so as to be tiltable. And, by tilting the snubber roll with a tilting cylinder provided at the end of the shaft, the pressing force on the outer peripheral surface of the coil is changed.

[0004]

However, in the winding control method for winding the strip while moving the tension reel in the axial direction, the tension reel is integrally moved to the drive side or the operation side of the tension reel. .
Therefore, when at least two strips meander in opposite directions (the drive side and the operation side of the tension reel), there is a problem that the side edges of the strips cannot be aligned.

Further, the winding control device described in Japanese Patent Application Laid-Open No. 5-31532 tilts an integrated shaft, so that one coil of a strip strip having two or more slits is used. Only the pressing force of the snubber roll could be applied. Further, since the winding control device is complicated and large, the same number as the number of slit strips cannot be arranged. For this reason, when at least two strips meander in different directions in opposite directions or in the same direction, there is a problem that the side edges of the strips cannot be aligned.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art. Even if at least two slit strips meander in opposite directions to each other, the present invention has been made in view of the above circumstances. It is an object of the present invention to provide a winding control device and a winding control method for a strip which can align the side edges of the belt.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail by taking, as an example, a case in which a coiled end of a two-strip strip is aligned and wound on a tension reel. First, a winding control device according to the present invention will be described. FIG. 1 is a schematic configuration diagram of a slitter line for winding a strip using the winding control device of the present invention, and FIG. 2 is a schematic plan view showing an arrangement of the winding control device of the present invention. 1 and 2, the description of the same symbols as those in FIGS. 7 and 8 will be omitted. 3a, 3b, 3c are meandering adjustment devices, 4 is a meandering operation control device, and 5 is a meandering detector. The tension reel 6 has a mandrel driven by a drive motor, but does not have a hydraulic cylinder. Therefore, the tension reel 6 does not move in the axial direction. Here, the pass line formed by the deflector rolls 8a and 8b and the slitter 2 is horizontal.
The drive side is the drive motor side of the tension reel 6, and the operation side is the side opposite to the drive motor side of the tension reel 6.

The meandering adjusting devices 3a, 3b, 3c have the same configuration. For example, as shown in FIG. 3, one of the meandering adjusting devices 3a has a member 30a having a smooth inclined surface on both sides and an eccentric cam mounted on a rotatable shaft 32a and abutting on the bottom of the member 30a. 31a, a sliding support member 33a slidably supporting the member 30a, and a shaft supporting member rotatably supporting the shaft 32a.
34a. Then, the member 30 of the meandering adjustment device 3a
a can be raised and lowered by rotation of the eccentric cam 31a, and the member 30a
Projecting from the pass line, the slope of the member 30a and the side end of the strip come into contact, and the meandering is corrected. The member 30a of the meandering adjustment device 3a has an angle θ formed by both slopes so that the side end of the strip can be moved in the width direction without greatly sliding up and down.
Is preferably 90 ° or more, and more preferably 120 to 150 °.
It has been. A felt or the like may be provided on the surface of the member 30a so as not to make a flaw even when it comes into contact with the strip.

The meandering adjusting devices 3a, 3b, 3c are arranged such that the slopes of the members provided on the meandering adjusting devices 3a, 3b, 3c can be brought into contact with the side edges of the strips 1a, 1b, respectively. Also,
The meandering adjusting devices 3a, 3b, 3c are arranged below the pass lines of the strips 1a, 1b between the slitter 2 and the deflector roll 8b. Further, the meandering adjusting devices 3a, 3b, 3c are movable in the width direction of the strip, and can cope with strips after slits having different strip widths.

The meandering detector 5 is, for example, a one-dimensional CCD camera, and is disposed on the downstream side of the deflector roll 8b and as close to the tension reel 6 as possible. It detects the side end positions of 1a and 1b. Further, as shown in FIG. 2, the meandering detector 5 has substantially the same length as the mandrel 6a, and can correspond to the maximum width of the slitter line.

As shown in FIG. 4, the meandering arithmetic and control unit 4 controls the deviation (the meandering amount) between the side end positions of the strips 1a and 1b after the slit detected by the meandering detector 5 and the target position. calculates the [Delta] d _i, based on the deviation, determines the presence or absence of occurrence of meandering. Then, the value S based on the meandering amount is calculated.
_{If i} exceeds the allowable value S _Mi , it is determined that meandering has occurred,
And it determines the walk adjustment device operated, the amount of projection of the members provided in the walk adjustment device operating to calculate on the basis of the S _i. The calculated rotation angle of the shaft that becomes the predetermined amount of protrusion is calculated, and the meandering adjustment device is operated so as to have the calculated predetermined rotation angle. Then, the operated member of the meandering adjustment device protrudes by a predetermined amount on the pass line, and by contacting the slope of the member with the side end of the band plate, the meandering is corrected, and the side end of the band plate is aligned. To be wound around the tension reel 6. On the other hand, the value S based on the meandering amount
_{When i} becomes equal to or less than the allowable value S _Mi , it is determined that there is no meandering, and the member is lowered from the pass line to the standby position.

Next, the operation of the winding control device of the present invention when the two strips meander in opposite directions so that the gap between the strips 1a and 1b wound on the tension reel 6 becomes narrower. Will be described with reference to FIGS. That is, the band plate 1a meanders to the drive side, the band plate 1b meanders to the operation side, and the interval between the band plates 1a and 1b is becoming narrower. When the meandering is not occurring, the meandering adjustment devices 3a, 3b and 3c are at the standby position. For example, as shown in FIG. 5, in the meandering adjusting device 3b at the standby position, the distance between the lower end of the member 30b and the upper end of the shaft 32b is the narrowest, and the position of the member 30b is the lowest. And strip
1b is a state where it is not in contact. When the band plate 1a meanders to the drive side and the band plate 1b meanders to the operation side from the state of the standby position, the side of the band plate 1a, 1b after the slit detected by the meander detector 5 is detected. When the value based on the deviation (the meandering amount) between the end position and the target position, for example, a value obtained by multiplying the meandering amount by a constant, increases and exceeds the allowable range, the meandering operation control device 4
It is determined that meandering has occurred in 1a and 1b. Then, the meandering arithmetic control unit 4 determines that the meandering adjustment device to be operated is 3b because the band 1a meanders to the drive side and the band 1b meanders to the operation side, and sets 3a and 3c to the standby positions. Leave it alone. Next, for example, on the basis of a value obtained by multiplying the meandering amount by a constant, the meandering adjustment device 3b
The protruding amount of the member 30b provided from the path line is calculated, the rotation angle of the shaft 32b which is the calculated predetermined protrusion amount is calculated, and the meandering adjustment device is adjusted so that the calculated predetermined rotation angle is obtained. Operate 3b. Then, the member 30b of the operated meandering adjustment device 3b protrudes by a predetermined amount on the pass line, so that the slope of the member 30b is shifted to the driving side end of the band plate 1a and the operation side of the band plate 1b. Since it comes into contact with the end, the strip 1a acts to move to the operation side, and the strip 1b acts to move to the drive side. As a result, as shown in FIG. 6, the interval between the strips 1a and 1b is increased, so that the side edges of the strips 1a and 1b wound on the tension reel 6 are aligned. When the value obtained by multiplying the meandering amount by a constant decreases and falls within the allowable range, it is determined that meandering has not occurred, and the meandering adjustment device 3b is set to the standby position.

Next, a case where the two strips meander in opposite directions so that the gap between the strips 1a and 1b wound on the tension reel 6 is widened will be described. That is, this is a case where the band plate 1a meanders toward the operation side and the band plate 1b meanders toward the drive side. In this case, the meandering operation control device 4
For example, when the value obtained by multiplying the meandering amount of the strips 1a, 1b by a constant increases and exceeds the allowable range, the meandering adjustment device to be operated is 3a,
3c is determined, and 3b remains at the standby position. Then, based on the value obtained by multiplying the meandering amount by a constant, the protrusion amounts of the members provided in the meandering adjustment devices 3a and 3c are respectively calculated, and the calculated rotation angles of the shafts that are the predetermined protrusion amounts are calculated, respectively. The meandering adjustment devices 3a and 3c are respectively operated so as to have the calculated predetermined rotation angle. And the operated meandering adjustment device
When the members provided on 3a and 3c protrude by a predetermined amount on the pass line, the slope of the member 30a provided on the meandering adjusting device 3a comes into contact with the side end on the operation side of the strip 1a, and the meandering The slope of the member provided on the adjusting device 3c comes into contact with the driving-side end of the strip 1b. Therefore, the band plate 1a moves to the drive side, and the band plate 1b acts to move to the operation side, and the band plate 1a,
The gap of 1b becomes narrow, and the side edges of the strips 1a and 1b wound on the tension reel 6 can be aligned. When the value obtained by multiplying the meandering amount by a constant decreases and falls within the allowable range, it is determined that meandering has not occurred, and the meandering adjustment devices 3a and 3c are set to the standby positions.

As described above, even if the two strips 1a and 1b meander in opposite directions, the present invention allows the strips 1a and 1b to be wound on the tension reel 6 with their side edges aligned. It is. By the way, even if one of the two strips 1a, 1b meanders, or both meander in the same direction, in the present invention,
In the following manner, the strips 1a and 1b can be wound on the tension reel 6 with their side edges aligned.

For example, a case of meandering to the operation side will be described. When the strip 1a meanders to the operation side, the meandering arithmetic control unit 4 determines the meandering adjustment device to be operated as 3a,
Leave 3b and 3c in the standby position. Then, by bringing the slope of the member 30a provided in the meandering adjusting device 3a into contact with the side end of the band plate 1a on the operation side, the band plate 1a moves to the driving side, and the band plate 1b has Since the members are not in contact with each other, the band plate wound around the tension reel 6
The side edges of 1a and 1b are aligned.

When the strip 1b meanders to the operation side, the meandering arithmetic and control unit 4 controls the meandering adjustment device to be operated by 3a.
And 3b, and 3c remains at the standby position. Then, by bringing the slope of the member 30b provided in the meandering adjustment device 3b into contact with the side end on the operation side of the band 1b, the band 1b is moved to the drive side, and the members of the meandering adjustment devices 3a and 3b are moved. Are brought into contact with both side edges of the strip 1a to prevent the strip 1a from moving. As a result, the side edges of the strips 1a and 1b wound on the tension reel 6 are aligned.

When the strips 1a and 1b meander to the operating side, the meandering arithmetic control unit 4 operates the meandering adjusting device 3a in the same manner as when the strip 1b meanders to the operating side. By leaving the standby position at 3c, the side edges of the strips 1a and 1b wound on the tension reel 6 can be similarly aligned. The case where the strip is slit into two strips has been described above. However, even with two or more strips, according to the present invention, the side edges of the strip wound on the tension reel can be aligned.

Although the meandering adjustment device used in the present invention has been described as a member having slopes on both sides, the meandering adjustment device may be provided with a member having a slope on one side. By arranging the meandering adjustment device having a member having a slope on one side at the side end of the band plate, it is wound around a tension reel in the same manner as the meandering adjustment device having a member having a slope on both sides described above. The side edges of the two or more strips can be aligned.

The present invention is suitable for a metal strip such as a steel plate, a copper plate, and an aluminum plate.

As described above, according to the winding control method of the present invention, even if at least two strips meander in opposite directions, the side edges of the strips are aligned and wound on the tension reel. Can be taken. Further, the winding control device of the present invention includes:
Since it is compact, it can be arranged below the side edge of the strip, and even if at least two strips meander in opposite directions, the side edges of the strip can be aligned and wound on a tension reel. it can. Furthermore, the present invention provides that even if one of the at least two strips meanders or meanders in the same direction,
The side edges of the strip wound around the tension reel 6 can be aligned.
