BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding material strain / loosening device.

[0002]

2. Description of the Related Art Conventionally, when winding a winding material for an element such as paper, cloth, film, metal foil, etc. in the production of any other wound material such as an electrolytic capacitor element, the wider the width of the material is, Or, as the thickness of the material becomes thinner, the inherent strain and slack in the material occur, and the effect of this causes winding wrinkles and winding disorder during winding, which often causes the problem that the quality of the element remarkably deteriorates. Was done.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winding material strain / slack eliminating device for solving the above problems.

[0004]

As a result of earnest research for achieving the above-mentioned object, the inventor of the present invention absorbs the inherent strain / sag of the material during winding, between the respective guide rollers. Based on this finding, we came up with what we needed, and from a plurality of loosely adjoining rollers supported individually by a single shaft provided on the pedestal and supported by an elastic body from below. The inventors have come up with a device for removing strain / slack of a winding material.

Specifically, the strain of the winding material of the present invention
The slack eliminating device is configured by gently adjoining a plurality of rollers formed by dividing a tubular body that penetrates a hole through which a shaft passes through the center of a metal round bar into a plurality of annular bodies having substantially the same width. In this manner, the device is configured to pass through a single shaft provided on the gantry, individually rotatably supported by the shaft, and supported by an elastic body from below.

Here, "with sufficient play" means that there is a distance between the shaft and the inner diameter of the roller such that the roller can be displaced by the elastic body. Further, “slowly adjacent” means that adjacent rollers are adjacent to each other to the extent that they do not interfere with each other's rotation due to friction or the like.

A winding material strain / slack eliminating device of the present invention will be described with reference to the drawings. As shown in FIG. 1, the pedestal 3
A plurality of rollers 1 are loosely and adjacently passed through a single shaft 4 provided in each roller 1. Each roller 1 is independently and rotatably supported, and each elastic body 2 is independently supported.
Supported from below. Thus, each roller has an independent spring effect.

Therefore, when the device of the present invention is attached to the winding traveling line, a plurality of rollers individually come into close contact with the material according to the distortion / loosening of the material during winding and the distortion / loosening is prevented. Can be absorbed.

The winding / distorting device for winding material according to the present invention can be freely carried and, if necessary, can be used by arbitrarily and appropriately installing it in the winding traveling line. In practice, it was most effective when the contact angle with the material was about 30 degrees.
