DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for controlling meandering of a laminated substrate such as a film (sheet).

[0002]

2. Description of the Related Art As a method of controlling meandering of a film or the like, a method of inclining a feed roll of a traveling system, a method of using a taper roll in the traveling system, and the like have been proposed.
Various methods for sorting the film after slitting into a plurality of strips have been proposed.

On the other hand, as a method of laminating a film on a steel plate or the like, the film is slit into a plurality of strips in advance, and a predetermined interval (dry laminating portion) is provided between the slit products on a single or multi-axis unwinding shaft. Set
There is a method in which each slit product is unwound and bonded to a steel plate or the like on a laminating roll.

[0004]

By the way, in the above-mentioned laminating method, it is necessary to separately provide a step of slitting the film before performing the laminating treatment. Also,
When the unwound slit product (film) is guided to a laminating roll, flare may be generated and the film may meander. Therefore, laminating the film accurately at a predetermined position such as a steel plate, that is, the dry laminating part may be precisely laminated. It is difficult to make well.

As a method of accurately forming a dry laminated portion, there is a method of laminating a film over the entire surface of a steel plate or the like, and then cutting and peeling off a portion corresponding to the dry laminated portion. There is a problem of loss.

The present invention has been made in view of such circumstances, and in a process of laminating a laminated substrate such as a film on a surface of a steel plate or the like using a laminating roll, displacement of the laminated substrate sent to the laminating roll. It is an object of the present invention to provide a method of controlling meandering of a laminate substrate, which can eliminate the problem.

[0007]

In order to achieve the above object, a meandering control method for a laminated base material according to the present invention is characterized in that a plurality of rotatable small-diameter rolls are provided on a predetermined circumference between side plates facing each other. And both ends of each small-diameter roll are movably supported by side plates, respectively,
A meandering adjustment roll, in which at least one of the side plates is configured to be rotatable around the center of the circumference, is arranged at the preceding stage of the laminating roll, and runs while the laminating base material is in contact with the small-diameter roll of the meandering adjusting roll. Then, the meandering is controlled by rotating the side plate of the meandering adjusting roll according to the meandering amount of the laminate substrate.

As described above, in the meandering adjusting roll used in the meandering control method of the present invention, at least one of the side plates is rotatable, and both ends of each small-diameter roll are movably supported by the side plates. As illustrated in FIG. 1 and FIG. 6, when the side plates 11 and 12 are rotated, the small-diameter rolls 10.
The whole of 10 is in a twisted state, and each small-diameter roll 10 is inclined. When the small-diameter roll 10 is tilted in this manner, the film F (laminate base material) passing through the meandering adjustment roll 1
Is moved to the right or left in the film width direction. Therefore, by disposing such a meandering adjustment roll in front of the laminating roll, detecting the edge position of the film toward the laminating roll, and adjusting the rotation amount of the meandering adjusting roll based on the detection result, the meandering of the film is achieved. Can be eliminated.

Here, the meandering control method of the present invention is a method of unwinding a single-width film, slitting the film into a plurality of strips, distributing each slit product at a predetermined interval, and forming a dry laminated portion on a steel sheet or the like. It can also be applied to the lamination process.

More specifically, as shown in FIGS. 1 and 2, a plurality of small-diameter rolls 10 are arranged (two rows) along the width direction of a single-width film F to be unwound. The meandering adjusting roll 1 is
5 and the slit product Fs slit in the preceding stage of the meandering adjustment roll 1 is placed in the small-diameter roll 1 in each row.
Assign it to 0. Then, a gap between the divided slit products Fs is detected (edge position detection), and based on the detection result, the side plate 11 of the meandering adjustment roll 1 is
A method of controlling the gap D between the slit products Fs (see FIG. 8) by adjusting the rotation amount of the slit 12 is exemplified.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the meandering control method of the present invention will be described below with reference to the drawings.

First, as shown in FIGS. 1 and 2, the equipment for implementing the control method of the present invention includes an unwinding shaft 101 for setting a film F for lamination in a roll state, a feed roll 102, and a slit for slits. Roll 103 and score blade 1
04, a laminating roll 105 and the like are arranged,
The film F unwound from the unwinding shaft 101 is attached to the score blade 10
4, the slit product Fs is branched into two slit products Fs, and the slit products Fs are supplied together with the steel sheet S to the laminating roll 105 in a state where the slit products Fs are distributed at a predetermined interval. As shown in FIG. Film F in place
Are laminated while forming a dry laminating section A having a predetermined width.

In the present embodiment, two meandering adjusting rolls 1 are arranged on the film running between the slit roll 103 and the laminating roll 105 to sort and meander two slit products Fs. There is a characteristic in the control.

As shown in FIGS. 3 to 6, the meandering adjusting roll 1 has two movable side plates 11, 12 connected to each other by a spline shaft 20, and is located at an intermediate position between the two movable side plates 11, 12. The fixed side plate 13 is provided.

Two movable side plates 11, 12 and fixed side plate 1
Numerals 3 are circular plates having the same diameter, and are arranged so as to face each other. One of the movable side plate 11 and the fixed side plate 13, and the other movable side plate 12 and the fixed side plate 13
, Each has a plurality of small-diameter rolls 10... 10
Is arranged. Note that both ends of the spline shaft 20 are supported by bearings (not shown).

The small-diameter rolls 10,...
They are arranged along a circumference (on a semicircular arc) centered on the zero rotation center. As shown in FIG. 6, each end of the small-diameter roll 10 is provided with a pin 14 provided perpendicular to the fixed side plate 13.
And is rotatably (self-rotating) supported via a movable bearing portion 15. The movable bearing 15 has a structure in which a spherical concave surface and a spherical convex surface are combined, and the support angle of the small-diameter roll 10 with respect to the fixed side plate 13 can be changed within a certain range. Although not shown, the other end of the small-diameter roll 10 is supported by movable side plates 11 and 12. Each supporting portion is also provided with a pin 14 and a movable bearing portion 15 having the same structure as described above, and a small-diameter roll 10 on the movable plates 11 and 12 is provided.
Is also movable.

An actuator 2 is connected to the meandering adjustment roll 1. As shown in FIGS. 3 and 5, the actuator 2 includes one movable side plate 1 of the meandering adjustment roll 1.
1, a spur gear 22 meshing with the spur gear 21, a control motor 23 for rotating the spur gear 22, and the like. The control motor 23 drives the meandering adjustment roll 1. As one of the movable plates 11 rotates, this rotational force is transmitted to the spline shaft 20 via the movable side plate 11 and the boss member 24, and the other movable side plate 12 also rotates in the same direction. Note that the fixed side plate 13 of the meandering adjustment roll 1 is not connected to the spline shaft 20, and the fixed state is always maintained regardless of the rotation of the spline shaft 20.

In the meandering adjusting roll 1 having the above structure,
When the two movable side plates 11 and 12 at both ends are rotated, the group of two small-diameter rolls 10 is twisted as a whole, and each small-diameter roll 10 is tilted. Two slit products F passing through the adjustment roll 1
The edge position in the width direction of s can be moved to the right or left in the width direction. The amount of movement of the edge position of the slit product Fs is arbitrarily controlled within a certain range by adjusting the amount of rotation of the movable side plates 11 and 12 (hereinafter referred to as the torsion angle of the meandering adjustment roll 1). can do.

In this embodiment, as shown in FIGS. 2 and 7, an edge sensor 4 for detecting the edge position of the slit product Fs is provided between the meandering adjusting roll 1 and the laminating roll 105. The output of the edge sensor 4 is fed back to the controller 5.
In this example, a gap D (see FIG. 8) between the edges of the two slit products Fs sent to the laminating roll 105 is detected by the edge sensor 4.

The controller 5 has two slit products F
The target value of the gap D of s, that is, the width dimension (target value) of the dry laminate portion A is input, and the target value is compared with the value detected by the edge sensor 4, and the meandering is performed so that there is no difference between the two. The drive of the actuator 2 of the adjustment roll 1 is controlled.

Specifically, when the value detected by the edge sensor 4 (actual gap D) is smaller than the target value, the twist angle of the meandering adjustment roll 1 is increased, and
By increasing the inclination angle of 0, the gap D between the edges of the two slit products Fs approaches the target value, and
When the value detected by the edge sensor 4 is larger than the target value, the twist angle of the meandering adjustment roll 1 is reduced, and the inclination angle of each small-diameter roll 10 is reduced.
Control is performed such that the gap D between the edges approaches the target value. And by performing such control,
The two slit products Fs can be sent to the laminating roll 105 without meandering, and as a result, the slit products Fs, that is, the slit films F, can be accurately laminated on predetermined positions of the steel sheet S, and can be dried. The dimensional accuracy of the lamination part A (see FIG. 9) can be improved.

Here, in the above embodiment, a case where a single-width film is slit into two strips and the slit product is distributed to two meandering adjusting rolls to control the meandering has been described. The invention is not limited to this, and a plurality of meandering adjusting rolls in which three or more small-diameter roll groups are arranged are arranged in front of a laminating roll, and are slit into multiple strips while unwinding a single-width film. It is also possible to control the meandering by allocating the slit products to small-diameter rolls in each row of meandering adjusting rolls.

In addition to the laminating method of forming a dry laminating part by performing slitting and sorting as described above,
Unwound single width film as it is (Article 1)
The meandering control method of the present invention can also be applied to a method of laminating a film at a predetermined position on a steel sheet by feeding the film to a laminating roll. In this case, the meandering adjustment roll is 1
It goes without saying that it is a ream.

The meandering adjusting roll used in the above embodiment has a structure in which only one of the two side plates supporting both ends of the small-diameter roll (the movable side plates 11 and 12) is rotated. However, the present invention is not limited to this, and the present invention can be implemented even if a meandering adjustment roll having a structure that rotates both of two side plates supporting both ends of the small-diameter roll is used.

[0025]

As described above, by adopting the meandering control method of the present invention, a laminated substrate such as a film (sheet) can always be accurately laminated on a target position such as a steel plate. In addition, lamination defects can be reduced.

Further, if the meandering control method of the present invention is applied to a process in which a single-width film is unwound and slit into a plurality of strips, and the slit products are distributed at predetermined intervals and laminated on a steel plate or the like, The dimensional accuracy of the dry laminate portion can be increased without causing a loss of the base material.

Moreover, according to the meandering control method of the present invention,
Since it is only necessary to add a meandering adjustment roll and its control system to the existing laminating equipment, the above-described excellent effects can be achieved with a simple and compact equipment.
