Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a soft strip-shaped material that can be used when a soft strip-shaped material such as a steel breaker used in a tire manufacturing process is wound around a winding drum. And a winding device.

[0002]

2. Description of the Related Art In a tire manufacturing process, carcass members, sidewalls, and other tire constituent materials are successively attached to a rotatably formed molding drum to assemble a tubular green case which is the original shape of the tire. To do so. Most of these tire components have long strips that are manufactured in a separate process in advance, but if the manufacturing efficiency is considerably faster than the work efficiency of assembling the green case (for example, steel breaker It is necessary to stock in some form at the end of the manufacturing process.

By the way, since this kind of tire constituent material is manufactured in a strip-like long shape as described above, and is soft and adhesive (hereinafter referred to as "soft strip material"), As a stocking method, for example, it is preferable to wind the bobbin-like winding drum around the outer periphery while rotating the winding drum, and at the time of winding, to prevent mutual adhesion between the windings, a soft strip material is used. At the same time, a stripping film made of resin (a sheet made of poly sheet is generally called "liner") is wound together.

[0004]

When it is attempted to start winding the soft band-shaped material around the winding drum, the separation film is wound around the winding drum by a predetermined length prior to this. The separation film is wound up when the winding drum is rotated. Then, after that, the soft band-shaped material is started to be wound along the separation film. Therefore, it is necessary to wrap the separation film around the take-up drum for at least a few turns and strongly tighten it at the very beginning, if this is not done, the take-up drum will not rotate. Even if it was done, the separation film could not be wound up.

On the other hand, after the soft strip has been wound up to a predetermined length, the soft strip is cut, and the tail end formed by this cutting is wound on a winding drum. Also, the winding drum is further rotated so that the separation film is wound around the winding drum several times. After that, the diverging film is cut, but at this time, it is necessary to fit a large rubber band on the outer periphery of the diverging film so that the tail end of the diverging film does not come apart.

The operation of winding and tightening the deviation film at the start of winding for a few turns and the operation of fitting the rubber band to the deviation film at the end of winding are extremely complicated. Since automation has been difficult or impossible, conventionally, the winding operation of the soft band-shaped material has been performed almost entirely by hand. Therefore, the work efficiency is inferior, and it has been a major obstacle to improving the production efficiency of the soft strip material and the tire. In addition, it has been an obstacle to reducing the manufacturing cost.

The present invention has been made in view of the above circumstances, and aims at automating a series of operations for winding a soft strip-shaped material on a winding drum, thereby improving the work efficiency and not only the soft strip-shaped material but also the related material. An object of the present invention is to provide a winding method and a winding device for a soft band-shaped material that can improve the production efficiency of products (tires and the like) and reduce the manufacturing cost.

It is characterized in that the separating film is wound up by a predetermined length, and then the soft strip-shaped material is supplied to the winding drum along the separating film.

When the separation film is attached to the take-up drum, the tip of the adhesive tape is attached to the outer peripheral surface of the take-up drum in advance, and the adhesive tape is specified before, after, or in parallel with this. Cut it to length and make the other end of the adhesive tape hang down from the winding drum.Insert the tip of the separation film between the outer peripheral surface of the winding drum and the adhesive adhesive surface of the adhesive tape, The non-adhesive surface of the tape may be pressed against the winding drum.

In the winding method of the present invention according to claim 3, the stripping film and the soft strip-shaped material are wound in a state in which the winding drum is rotated while the strip-shaped separation film and the soft strip-shaped material are overlapped, After the winding length of the soft strip material reaches a predetermined value, only the soft strip material is cut, and the deviation film is wound up by a predetermined length by rotating the winding drum several times, and then,
It is characterized in that the diverging film is cut, and the tail end portion produced by the cutting is attached to the outer peripheral surface of the diverging film wound on a winding drum with an adhesive tape.

Therefore, the separation film can be easily and surely wound around the winding drum. Also, by adopting such a method, automation becomes possible. Therefore, the work efficiency can be improved, the production efficiency of the related products (tires and the like) as well as the soft strip-shaped material can be improved, and the manufacturing cost can be reduced.

On the other hand, at the end of winding, since the tail end of the diverging film is attached to the outer peripheral surface of the diverging film with an adhesive tape, the diverging film is sure to be separated. Will be able to prevent. Further, by adopting this method, automation becomes possible. Therefore, the work efficiency can be improved, the production efficiency of the related products (tires and the like) as well as the soft strip-shaped material can be improved, and the manufacturing cost can be reduced.
