Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method of winding a work such as a very narrow tape or film on a tapered bobbin whose inner wall surface of a flange is expanded outward.
[0002]
[Prior art]
Conventionally, a thin ultra-thin tape, film and the like have been wound on a bobbin with a flange. However, there are problems such as collapse of the roll and work dropping into the inner layer on the flange surface, and only a small amount can be wound. In addition, as a method of winding a tape, a very thin tape or a film which is easy to stretch on a taper bobbin, there is a bobbin drive winding which drives the taper bobbin itself by a general winding method and winds it with a guide traverse, but only the bobbin drive. In the case of winding, there has been no good method for the work to be stretched by the winding tension, wrinkles to be generated in the inner layer due to tightening of the winding, or to generate a streak-like hump called a so-called bone in the winding shape. .
Also, when winding a work on a flanged bobbin with a parallel flange or a bobbin without a flange, winding by the surface roller method, in which the bobbin is brought into contact with the surface of the driven roller, is wound without stress on the work Although a result can be obtained, this type of bobbin has a disadvantage that it is difficult to unwind the work.
There has been a demand for a method of winding the tape on a tapered bobbin having a good work unwinding property.
If a roller that expands and contracts can be wound on a tapered bobbin as a surface roller, ideal winding can be performed, and unwinding can be performed without any trouble in use in a subsequent process.
[0003]
[Problems to be solved by the invention]
However, if a surface roller type winding is to be performed on a tapered bobbin whose inner wall surface is expanded outward, a roller whose length gradually changes as the work is rolled up is required. Was. In view of the above, the present invention provides a method for solving the problem by traversing the roller within the range of the inner width of the collar so that the roller length gradually changes in accordance with the winding of the work so as to perform an equivalent function. In recent years, for ultra-thin films and tapes, highly accurate and highly efficient (high yield) products have been strongly demanded because of the demands for extremely high precision and compactness of precision electronic devices and economical reasons. The wound product can be used only when there is a winding that is easy to unwind. Therefore, the present invention has been made to solve these problems.
[0004]
[Means for Solving the Problems]
That is, the present invention is an active drive roller having a mechanism capable of varying the traverse width, and while traversing according to the flange width of the tapered bobbin, and driving and winding the bobbin, always has an effective length that is full of the flange width. The present invention provides a winding method capable of winding up a surface roller, which can be wound up like a surface roller winding having a taper bobbin.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The tape or film continuously coming out of the preceding process is wound up by a surface roller method on a tapered bobbin which is rotated by a roller which is actively driven. Since the distance between the flanges increases with the winding, the roller is traversed by the width less than the roller width, so that the surface roller length always has the function of matching the flange width. .
[0006]
Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited thereto.
Further, in the present embodiment, the case where the rollers are traversed is described, but it is a relative viewpoint, and the same effect can be obtained by the method of traversing the bobbin.
FIG. 1 shows the relationship between two rollers at the beginning of winding and one taper bobbin, and FIG. 2 shows the relationship between two rollers and one taper bobbin during winding.
At the beginning of the winding, the two rollers are not traversed because the width of the two rollers and the inner width of the bottom of the one taper bobbin are the same. Since the two rollers are driven, the one taper bobbin in contact therewith takes up three workpieces. At this time, an appropriate system including a guide traverse system can be considered for the traverse of the three works, but there is no particular restriction. The two rollers are traversed in the direction of the arrow according to the winding thickness. The traverse width is gradually increased from the winding start state to the winding state in FIG. 2 so that two rollers always traverse the inner width of the bobbin flange. The unevenness of the hardness of the wound layer that occurs when the two rollers are wound up to full winding while being fixed is also made uniform by the two rollers traversing.

【The invention's effect】
As described above, according to the present invention, it is possible to provide a method capable of winding an ultra-thin tape or film, which has been impossible until now, on a tapered bobbin in which the inner wall surface of the flange is expanded outward. .
