Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat bobbin winding device for winding a long product.

2. Description of the Related Art Conventionally, in order to wind a long object, it is common sense to wind the cross section into a round shape, and the structure is as shown in FIG. That is, the roll 1 is wound from a round shape to a round bobbin 2, and the long piece running portion between the roll and the winding bobbin wrinkles the long piece 4. In addition, several parallel rollers 3 are fixed and arranged to prevent meandering. 3a is a parallel roller for the final guide.

With such a structure, the long object traveling speed at the point A sent from the original fabric and the original material side rotation speed for keeping the long object traveling speed at the point B wound on the winding bobbin constant, The control of the number of rotations of the winding bobbin is easy because the number of rotations changes gradually due to the change in the winding diameter.

Problems to be Solved by the Invention However, with such a structure, when a long object is wound on a flat bobbin, as shown in FIG. 2, from C to D,
When the flat plate bobbin end is rotationally moved from D to E, the long object traveling speed at point B is repeatedly accelerated and decelerated. Therefore, the long object traveling speed at point A is set to the original revolution speed so that the same traveling speed is obtained. If you try to control by, the long object meanders or wrinkles occur and you can not wind it neatly,
Further, there is a problem in that a long product having a small tensile strength is cut.

Means for Solving the Problems The means of the present invention for solving the above problems is a raw material around which a long material is wound, and a long material which is configured to be rotatable around one point as a fulcrum and is supplied from the raw material. A flat-plate bobbin that winds up an object, a plurality of rollers that are provided in a long-object traveling portion between the original fabric and the flat-plate bobbin to guide the long object and generate tension, and synchronize with the flat-plate bobbin. And a roller connecting rod that is connected to a movable roller of the plurality of rollers that is movably provided and that transmits the displacement of the cam to the movable roller to move the cam. The displacement curve moves the moving roller in accordance with the change in the amount of slack that occurs in the long object traveling portion as the traveling speed of the long object wound by.

Action The action of this means is as follows. That is, when the long object speed on the flat plate bobbin side becomes faster, the roller is raised, and when it becomes slower, the roller is lowered, so that the original material side long object traveling speed is kept constant.

Example Hereinafter, an example of the present invention will be described with reference to FIG.
A long object 14 drawn from a material roll 11 on which a long object is wound
Is passed through the guide parallel rollers 13 and hung on the vertically moving parallel rollers 15, and again passed between the guide parallel rollers 13 and wound on the flat plate bobbin 18. The cam 17 that rotates in synchronization with the flat bobbin 18 via the timing belt is a roller connecting rod.
Vertical movement through 16 Moves the parallel roller 15 up and down.
The vertical movement timing is as follows. That is, when the end of the flat bobbin 18 moves from the position C to the position D,
Since the moving speed of the end of the flat bobbin 18 becomes faster than that of the final guide roller 13a, the vertically moving parallel roller 15 is raised. Further, when the end of the flat plate bobbin 18 moves from the position D to the position E, the moving speed of the end of the flat plate bobbin 18 becomes slower than that of the final guide roller 13a, so that the vertically moving parallel roller 5 is lowered.

EFFECTS OF THE INVENTION As described above, according to the present invention, by mounting the vertically moving parallel rollers, the long object can be wound on the flat plate bobbin without meandering or wrinkling.
