Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to slits for winding two or more slit materials obtained by continuously dividing a metal strip in the width direction into a coil by a winding machine. The present invention relates to a slit material winding device that appropriately maintains a gap.

[Prior Art] Conventionally, in a slit material winding device, when a narrow band is required, a slitter is arranged on the entrance side of the winding machine and a wide band is continuously stretched in the band width direction. Are divided (parallel to the rolling direction) and wound into coils.

For example, after a slitter, a separator is used to secure a gap, and after passing through a deflector roll, each is wound by a single winding machine.

However, in such an apparatus, the variation of the slit gap caused by the band property of the slit material cannot be completely adjusted by the separator, and the slit gap is narrowed and deformed when the slit material edge is pressed against the separator. Moreover, since it is not possible to adjust the slit gap even if it fluctuates, it is not possible to prevent the slit materials from being overlapped with each other or the both edges of the coil from being uneven. For this reason, the line speed is lowered and the coil quality is allowed to be somewhat deteriorated.

Alternatively, a plurality of winders are arranged, the position of the edge of the slit material is detected, and each winder is moved in the band width direction to adjust the slit gap according to the amount of movement of the edge.

[Problems to be Solved by the Invention] The conventional winding device has the following problems to be solved.

That is, the conventional device has various problems such as requiring an expensive winding machine equipped with the band width direction moving means and a plurality of accessory devices thereof.

The present invention has been proposed in order to solve the above problems, and in order to reduce the space required for a single winding machine and maintain the coil quality, it is also possible to speed up the line.
An object of the present invention is to provide a slit material winding device that appropriately maintains a space gap.

[Means for Solving the Problems] As a means for solving the above problems, the present invention relates to an apparatus for winding two or more slit members obtained by continuously dividing a metal band in the band width direction with a winding machine while keeping a gap, When viewed in a plane, two or more rollers that are provided so as to be substantially orthogonal to the traveling direction of each slit material and whose axis can be tilted with respect to the horizontal plane, and that individually press each slit material from above or below, And a control means for detecting a difference between an appropriate position and a current position of each slit member when viewed on a plane and maintaining a predetermined gap by changing an inclination angle of the two or more rollers with respect to a horizontal plane. The present invention aims to provide a slit material winding device.

[Operation] Since the present invention is configured as described above, it has the following operation. That is, when the rotating roller is pressed against the slit material, the pressed slit material moves in the direction of being pressed higher. Utilizing this property, when viewed in a plane,
A roller provided so as to be substantially orthogonal to the direction of travel of the slit material and whose axis can be tilted with respect to the horizontal plane by pressing each slit material individually from above or below to make the slit material larger in the width direction. Control that enables movement to the pressed side, detects the difference between the proper position of each slit material and the current position, and changes the inclination angle of the roller with respect to the horizontal plane based on this difference to maintain a predetermined gap Promptly.

[Embodiment] An embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a side view and FIG. 2 is a plan view. In both figures, 10a is a work side roller that presses the work side slit material Wa, and 10D is a drive side roller that presses the drive side slit material WD. The bearing box (not shown) has an inclination angle of the roller with respect to the horizontal plane. A motor for changing (amount of pressing of each slit material in the width direction), that is, a servomotor or a hydraulic motor 7a, 7D is connected.

1 is a linear sensor type gap (S) detector,
It is arranged on the line center LC on the entry side of the winder 104 and is connected to the gap detection device 2. Reference numeral 5 is a feedback control device, which is a gap detection device 2, an AC servo controller 6a on the working side, and an AC servo controller on the driving side.
The 6D is connected to the respective motors 7a and 7D, and changes the vertical angle of the rollers 10a and 10D.

In this embodiment, it is arranged between the deflector roll 103 that applies a winding tension to the winder 104, and the variation of the gap of the slit material on the deflector roll and the entrance side thereof is changed immediately before the winder. It can be modified. At this time, the pass line of the slit material changes depending on the winding direction. Roll 10 due to changes in this pass line
The gap control cannot be performed due to the excess and deficiency of the a and 10D pressing amounts. That is, the change of the pass line of the slit material usually occurs in parallel to the width direction of the metal strip, but this causes the pressing amount to increase or decrease even when the roller does not contact the slit material. In this way, assuming a case where the gap control cannot be performed due to the change of the pass line, in the embodiment, as a preferable mode,
For this correction, a pass line detector 4 connected to the pass line detector 3 is arranged, and the rollers 10a and 10D are raised and lowered by the AC servo controller 9 via the pass line feedback controller 8.

In this embodiment, the AC servo controller 9 controls the parallel raising and lowering of the rollers, and the AC servo controllers 6a and 6D
The tilt angle of the roller with respect to the horizontal plane is controlled by.

The pass line correction is performed by using the fact that the pass line changes in accordance with the change in the coil diameter on the winding machine 104 in addition to the calculation based on the metal thickness, the line speed, and the operating time, and the pass line feedback control device. When the correction command is given to 8, there is no adverse effect due to the inclination of the slit material and the device is simple when the amount of rise and fall of the rollers 10a and 10D is large.

The control modes of these configurations are roughly classified into three modes. In the first mode, half of the difference in the gap S with respect to the target gap S ₀ is uniformly feedback-controlled.

In the second mode, the gap S is equally divided into two with respect to the line center LC, the target gap S ₀ is set, the edge position of the slit material in the gap S portion is detected, and each edge position is determined. Feedback control is performed to change the angle of each of the rollers 10a and 10D so as to correct the difference from 1 / 2S ₀ with respect to the LC point.

The third mode is a method in which the winding shape of the slit material is more emphasized. The edge position sensor 11 detects the position of the outer edge of the slit material WD on the driving side and transmits it to the edge position control device 12, and the position of this edge is detected. When the change occurs, the edge position control device moves the winder 104 in the plate width direction by the amount of change in the position of the outer edge, and holds the outer edge of the slit material WD on the drive side at the initially preset position. On the other hand, by comparing the target gap S ₀ and the gap S, only the working side roller 10a is feedback-controlled to keep the gap constant, so that the working side slit material also has a good winding shape.

In the embodiment, a gap control device is provided on the exit side of the deflector roll.
Although 13 is arranged, it goes without saying that they may be used on the entrance side.

If there is a long distance between the side trim 101 and the slitter 102 (even if they are coaxial with each other) to the deflector roll 103 or the winder 104, the gap control device 1 is also provided there.
It is preferable to dispose 3.

[Advantages of the Invention] A high-speed operation is possible while maintaining a good winding shape without damaging the edge of the slit material in a space-saving manner.
