Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a slit clearance when winding a slit material obtained by continuously dividing a metal strip in the plate width direction into a coil by a winding machine. The present invention relates to a slit material winding device that keeps a proper amount.

[Conventional technology]

Conventionally, in a slit material winding device, for example, when a narrow strip steel is required, a slitter is arranged on the inlet side of the winder, and the strip rolled to a wide width is oriented in the plate width direction (with respect to the rolling direction). It is continuously divided in the (orthogonal direction) and wound into a coil. 9 and 10 are a plan view and a side view of such a conventional device, in which both edges of the steel strip W to be fed are aligned by the side trimmer 101, and the central portion thereof is cut by the slitter 102. , Slit material divided in the plate width direction
_Let W _a , W _D. Then, the slit clearance x is secured by the separator disk 103, and the slit materials W _a and W _D are wound by the single winding machine 105 via the deflector roll 104.

However, in such a device, the variation of the slit clearance x generated by the plate properties of the slit materials W _a and W _D cannot be completely adjusted by the separator disk 103, and the slit clearance x is narrowed to reduce the edge thereof. Deforms when pressed against the separator disk 103, and does not narrow even if the slit clearance x widens. Therefore, it is possible to prevent the slit materials W _a and W _{D from being} rolled up during winding, It is not possible to align both edges of the coil.
For this reason, the line speed cannot be increased, and the problem described above is prevented by operating at a low speed.

In order to solve the above-mentioned drawbacks, recently, an apparatus as shown in FIG. 11 and FIG. 12 is used, and two winding machines 205 _a and 205 _b are provided and each slit material W is provided. The positions of the edges of _a and W _D are respectively detected by the edge position sensors 203 _a and 203 _D and the edge position control devices 204 _a and 204 _D , and the respective winding machines 205 _a and 205 _D are detected according to the moving amount of the edges.
Are moved in the plate width direction to adjust the slit clearance x, which corresponds to the speeding up of the line.

[Problems to be Solved by the Invention]

The conventional winding device described above has the following problems to be solved.

That is, in the conventional device, an expensive winding machine equipped with the plate width direction moving means and its ancillary equipment are required for two units, a vast space is required, and the maintenance management of the device becomes large. There is a problem that a large number of workers and expenses are required.

The present invention has been proposed in order to solve the above problems, and provides a slit clearance control device and a control method thereof for saving space with a single winding machine and for speeding up a line. The purpose is to do.

[Means for solving the problem]

The present invention, as a means for solving the above problems, in a device that winds each slit material on the working side and the drive side, which are obtained by continuously dividing a metal strip in the strip width direction, with a winding machine while maintaining a predetermined clearance, A pair of rollers that are substantially orthogonal to the traveling direction of the slit material when viewed in a plane and that can change the orthogonal angle and press each slit material from above and below, and the appropriateness of each slit material in the direction orthogonal to the traveling direction. An attempt is made to provide a slit material winding device characterized by comprising a control means for detecting a difference between a position and a current position and maintaining the predetermined clearance by changing the orthogonal angle of each of the pair of rollers. It is a thing.

[Action]

Since the present invention is configured as described above, it has the following effects. That is, not only the slit material, but generally, when a certain material is pressed and rotated by rollers (equal diameter), the pressed material has the same tangential velocity due to the rotation of both end surfaces in the direction orthogonal to the roller axis, so that the material at both ends is It is pushed out evenly. That is, the material is extruded in a direction orthogonal to the roller axis. Therefore,
If the slit material or the like is pressed by a pair of rollers from above and below in a direction substantially orthogonal to the traveling direction of the slit material and the orthogonal angle of the rollers is changed, the slit material or the like tends to direct the traveling direction toward the changed angle of the roller. It will be. By utilizing this property, the orientation of the slit material and the like, and hence the gap between the slit materials can be freely controlled by controlling the orthogonal angle of the rollers.

In the present invention, the orthogonal angle of each pair of rollers pressing each slit material divided from the metal strip plate from above and below in a direction substantially orthogonal to the traveling direction is defined as the proper position of each slit material in the orthogonal direction to the traveling direction and the present position. The difference (shift) from the position is detected and the control signal is used to properly adjust by the detection signal, so the clearance between each slit material, which is determined by the orientation of the slit material, can be adjusted freely and the prescribed clearance is maintained accurately. be able to.

To control the clearance amount x of both slit materials W _a and W _D by mode 3 using this device, refer to FIG. 3 and FIG.
As shown, mode 1, mode 2 and likewise both of the work side roll 11 _a, the roll cross angle theta _a drive-side roll 11 _D, preset the theta _D. And both slit materials
While W _a and W _D are being wound by the winder 205, the clearance amount x is detected by the clearance detector 1 and the clearance detection device 2 as in the mode 2, and is input to the feedback control device 3. Then converted to the OP workload Z _a in the comparison operation with the target gap amount S that is input to the gap amount x in advance, the working side
The motor 5 _a is operated by sending only to the AC servo controller 4 _a, only the roll cross angle θ _a of the work side roll 11 _a is adjusted, and the advancing direction of the work side slit material W _a is adjusted. On the other hand, the roll cross angle θ _D of the drive-side roll 11 _D remains at the initial preset position, the edge position sensor 203 detects the position of the outer edge of the slit material W _D on the drive side, and sends it to the edge position control device 204. Then, when the position of this edge fluctuates, the winder 205 is moved in the plate width direction by the amount of fluctuation of the position of the outer edge by the edge position control device 204, and the outer edge of the slit material W _D on the drive side is preset first. Hold in position.

As described above, according to the first and second embodiments, the gap detector 1 or the edge position sensor 20 detects the deviation from the proper position of the slit materials W _a and W _D that are divided and proceed from the strip plate.
If it is necessary to correct it by adjusting the roll cross angles θ _a and θ _D or both sides of the work side roll 11 _a and the drive side roll 11 _D through the feedback control device 3, each slit material is adjusted. There is an advantage that the gap between W _a and W _D can be always maintained properly.

Moreover, the work-side roll 11 _a, the drive-side roll 11 _D and feedback control device 3 such as a very small, since the obtained easily without the need for large space, and in addition to the low cost, maintenance also easy great work It has the advantage of not requiring personnel or expense.
