BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolled strip, a method for manufacturing the same, and an apparatus for manufacturing the same.

0002

[Prior Art] When winding a continuous strip onto a take-up reel that rotates around a horizontal axis, when the take-up diameter is small, it can be wound relatively easily and without loosening, but as the take-up diameter increases, The strip sag downward due to its own weight, causing loosening between the layers of the strip.

[0003] Therefore, normally, a certain tension is applied to the strip using a tension roller or the like that is biased in the direction of the strip, and the strip is wound tightly without loosening.

However, if an unnecessarily large tension is applied to the strip, there is a risk that the strip will be damaged or deformed.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a strip-wound body in which damage and deformation of the strip can be prevented and the strip can be wound without loosening, and a method and apparatus for manufacturing the same.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the strip-wound body of the present invention is formed by winding a continuous strip in multiple layers, and the strip has a portion with a small winding diameter. The structure is characterized in that the degree of adhesion of each layer in the part where the winding diameter is larger is greater than the degree of adhesion of each layer in the area where the winding diameter is larger. When winding around the axis, the tension is small when the winding diameter of the strip is small, and is increased as the winding diameter of the strip becomes large.

[0007] Furthermore, the apparatus for manufacturing a rolled strip body of the present invention includes:
A take-up reel that rotates about a horizontal axis is provided in a post-process of the tension adjustment member, and the tension adjustment member has a non-circular cross section, and the winding diameter of the strip to be wound on the take-up reel is small. has a configuration characterized by having a strip guide surface that applies a small tension to the strip and applies a large tension to the strip as the winding diameter of the strip increases.

[0008]

[Function] When the winding diameter is small and the strip's own weight is small, the tension applied to the strip is reduced to prevent damage to the strip, and the winding diameter increases, causing the strip to go around the take-up reel. When the weight of the band increases, apply strong tension to the band and tighten it without loosening.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an apparatus for manufacturing a wound strip body, which includes a take-up reel 2 and a tension adjustment member 3.
, a strip winding reel 4, a first guide roller 5,
It consists of a second guide roller 6 and a take-up reel drive device 7.

The take-up reel 2, the strip winding reel 4, and the guide rollers 5, 6 are each supported rotatably around a horizontal axis, and the take-up reel 2 is provided below the tension adjusting member 3 in a subsequent process. , a strip 8 made of interlayer paper wound on a strip winding reel 4 is guided by a first guide roller 5 and a tension adjustment member 3, and is supplied from above to a take-up reel 2, and then a strip 8 made of interlayer paper is wound on a strip winding reel 4. A continuous strip member 9 guided by 6 is also fed to the take-up reel 2 from above, and the strip 8 and the strip member 9 are overlapped with each other with the strip 8 facing upward and wound on the take-up reel 2. taken.

The take-up reel 2 is rotated by a take-up reel drive device 7, the first guide roller 5 is installed below the tension adjustment member 3 in the process before the tension adjustment member 3, and the second guide roller 6 is mounted below the tension adjustment member 3. It is attached to the front end of the take-up reel 2.

Further, the winding reel 2 has its winding start position A located directly below the strip contact surface of the tension adjustment device 3, or located slightly on the side opposite to the supply side of the strip 8. , the winding end position B of the take-up reel 2 is located on the supply side of the strip 8 from the strip contact surface of the tension adjustment device 3.

As shown in FIG. 2, the tension adjustment member 3 has a support roller 10, a support rod 11, and a tension roller 12, and the support roller 10 is rotatably or fixedly attached to the upper end of the support rod 11. The tension roller 12 is fixed to the lower end of the support rod 11, and the tension roller 12 is fixed to the lower end of the support rod 11.
is fixed to a supporting member such as a base (not shown), or is rotatably attached around the central axis of the support roller 10.

Therefore, when the support rod 11 is fixedly attached, the tension roller 12 is also fixed in a fixed position, and when the support rod 11 is rotatably supported, the pendulum movement of the tension roller 12 is possible. Become. Further, when the support rod 11 is rotatably attached, the tension roller 12 can be biased in the direction of contacting the strip 8 by a spring (not shown). The support roller 10 and the tension roller 12 have a non-circular cross-section in the direction of movement of the strip 8, and when the strip 8 is small after being wound onto the take-up reel 2, It has a strip guide surface that applies a small tension to the strip 8 and applies a large tension to the strip 8 as the winding diameter of the strip 8 increases.

Next, a method of using this winding body manufacturing apparatus 1 will be explained.

The take-up reel 2 is rotated by the take-up reel drive device 7, the strip 8 is pulled out in the direction of arrow a, and the strip member 9 is pulled out in the direction of arrow a', and the strip 8 and strip member 9 are pulled out at the winding start position A. Polymerizes and starts winding.

At this time, since the strip 8 is pulled out directly below the strip contact surface of the tension adjustment member 3 or toward the side opposite to the strip supply direction, the tension roller 12 of the tension adjustment member 3 is pulled out from the strip contact surface. There is no need to press 8.

As the winding progresses and the winding diameter of the strip wound body 16 increases, the pull-out directions of the strip 8 and the strip member 9 move in the directions of arrows b and b', respectively. The angle between the direction in which the strip 8 is supplied to the tension adjustment member 3 and the direction in which it is pulled out from the tension adjustment member 3 gradually becomes smaller, and the strip 8 is pressed against the outer surface of the tension roller 12 of the tension adjustment member 3. , the tensile force applied to the strip 8 gradually increases.

When the tension adjustment member 3 is attached to make a pendulum movement, its weight presses the strip 8, but when the tension roller 12 is urged downward by the spring as described above, When the winding diameter of the strip wound body 16 increases, the pressing force further increases.

FIGS. 3 and 4 show another embodiment of the tension adjusting member 3, in which the cross section along the traveling direction of the strip 8 is non-circular, and the winding diameter of the strip 8 wound on the take-up reel 2 is When the winding diameter of the strip 8 is small, a small tension is applied to the strip 8, and as the winding diameter of the strip 8 becomes large, a cam-shaped member 14 having a strip guide surface that should apply a large tension to the strip 8 and a cam-shaped member 14 provided near the upper end thereof is used. The upper part of the cam-shaped member 14 is made of a material with a small coefficient of friction, and the lower part is made of a material with a large coefficient of friction. Rotatably or fixedly mounted.

At the beginning of winding or when the winding diameter is small, the strip 8 is pulled out in the direction of the arrow c, and the tensile force applied to the strip 8 is small, but as the winding diameter increases, the pulling direction changes in the direction of the arrow c. Moving from d in the direction of arrow e, the strip 8 is pressed against the outer surface of the cam-shaped member 14, and gradually a larger tensile force is applied.

With the above-described winding body manufacturing apparatus, when winding the strip 8 around the horizontal axis while applying tension, the tension is reduced while the winding diameter of the strip 8 is small;
A method of manufacturing a strip wound body is performed in which the tension increases as the winding diameter of the strip 8 increases, and a continuous strip 8 is wound in multiple layers, and each layer of the strip 8 is wound in a portion where the winding diameter is small. A rolled strip body can be obtained in which the degree of adhesion of each layer in the portion where the winding diameter is larger is greater than the degree of adhesion of .

[0024]

[Effects of the Invention] In the strip-wound body of the present invention, since the degree of adhesion between each layer of the strip is increased in the portion where the winding diameter is large, the strip is wound tightly without loosening. Since the degree of adhesion between each layer is small in the portion where the winding diameter is small, an unnecessarily large tensile force is not applied to the strip, and there is no fear that the strip will be stretched, deformed, or damaged.

Furthermore, according to the method of manufacturing a wound strip body of the present invention, when the winding diameter of the wound strip body is small and the weight of the strip is small, unnecessary tensile force is not applied to the strip. When the winding diameter increases, the weight of the strip increases, and the strip tends to loosen, strong tensile force is applied to the strip, thereby preventing strip winding without loosening. You can get a body.

Furthermore, according to the apparatus for manufacturing a wound strip body of the present invention, by making the strip guide surface of the tension adjusting member have a specific structure, the degree of adhesion between each layer can be improved in the portion where the winding diameter is small. It is possible to very easily obtain a wound strip body which is large and has a high degree of adhesion between each layer in the portion where the winding diameter is large.
