Abstract

PURPOSE: To equalize the collecting tension of each fiber by collectively arranging dancers for controlling the tension of an optical fiber of each bobbin in a position just before the final guide wheel before an assembly point. CONSTITUTION: The center line from a center line rotating supply 21 is controlled with a rotating type dancer device 25 for the center line supply 21 to introduce each optical fiber from rotating type supplies 22 for the optical fiber into a rotating type dancer device 26 for controlling the tension for the optical fiber supply and collected in an assembly point 32. Dancer wheels, guide wheels for twisting back and the final guide wheel before the assembly point 32 are arranged in the dancer device 26.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in tension control for collective winding of optical fibers.

[Conventional technology]

2. Description of the Related Art Conventionally, examples of rotary collecting machines that collect filamentary bodies such as optical fibers and wind them onto bobbins are shown in FIGS. 1 and 2. This rotary winder has an unwinding device including a centerline rotating supply 1 and a centerline and optical fibers fed out from an optical fiber rotating supply 2. The optical fibers from the optical fiber rotating supply 2 are collected from the optical fiber supply bobbin 3 at the collection point 9 from the branch guide section 8 via the dancer wheel 5 and the guide wheel 6.7 by the feeding motor 4. A tape is wound on the filament body by taping a10, and a thread is further wound by a thread winder 11 and wound as a cable by a rotary winder 12.

By the way, such a winding machine uses a control dancer to control the tension of the optical fiber after it leaves the supply bobbin, but the distance from the dancer position to the gathering point is different at each supply position. It's different. For this reason, for those close to the supply position and the gathering point, the tension at the gathering point becomes the tension controlled by the dancer. Next, the tension of the supply far from the gathering point may change after it leaves the dancer due to the weight of the optical fiber, which is proportional to the distance to the gathering point, and the rotational resistance of the wheel.

However, even if the tension of the fiber changes significantly, external factors that occur between the dancer and the assembly point (for example, the fiber may come off the guide wheel) will cause the fiber to break, unless the fiber itself breaks. The striatum of the fibers will continue to aggregate. These fibers are combined to untwist the fibers, but fibers that are far from the gathering point have a defect in that the untwisting is difficult to transmit.

[Problem that the invention seeks to solve]

When using this rotary collecting machine, the tension of the optical fiber is controlled using a control dancer after it leaves each supply bobbin. In addition, the distance from each control dancer to the gathering point differs depending on the dancer position, and as a result, the weight of the optical fiber and the wheel weight are proportional to the distance from the dancer to the gathering point. Tension may change due to rotational resistance.

The present invention solves the above-mentioned problems of the conventional system, and by arranging and positioning the tension control dancers of each bobbin of optical fibers immediately in front of the collection point, the rotation supply can be controlled. It is intended to provide tension control.

[Means to Solve the Problems] In view of the above-mentioned points, the present invention has the following configuration. That is, in the tension control of the rotating supply according to the present invention, the center line from the center rotating supply is connected to the center line supply rotating dancer device, and the optical fibers from the plurality of optical fiber rotating supplies are connected to the optical fiber supply rotating dancer device. The device is used to control the center line and the tension of each optical fiber in the vicinity of the gathering point of both dancer devices, and perform taping and collective winding through the gathering point.

[Effect]

In the present invention, since the center line and the optical fiber are twisted by the rotating dancer device for each rotating supply near the assembly point, the optical fiber can be untwisted with low tension, and
It is designed to perform uniform collective winding with constant tension.

〔Example〕

The present invention will be explained below based on an embodiment shown in FIGS. 3 and 4.

In the tension control of the rotary supply of the optical fiber winding rotary type assembly machine according to the present invention, the unwinding device includes the centerline and optical fibers sent out from the centerline rotary supply 21 and the optical fiber rotary supply 22. The optical fiber from the optical fiber rotating supply 22 is almost the same as the conventional one until it is fed out from the optical fiber supply bobbin 23 by the feeding motor 24.

First, the centerline from the centerline rotation supply 21 is controlled by a centerline supply rotary dancer device 25.

Then, each optical fiber from the optical fiber rotating supply 22 is connected to the optical fiber supply rotating tension control dancer device a! Enter 26, dancer wheel 27
, and is untwisted through the guide wheels 28, 29, 30, and the final guide wheel 31 before the gathering point and the gathering point 32.
will be gathered at. By the way, such tension control is carried out by combining the tension control dancers of the optical fibers of each bobbin.
It is placed at the location of the device 26 immediately in front of the final guide wheel 31 before the assembly point, and the tension control of each fiber is made equal distance, and the optical fibers are assembled stably without straining. It is a rotary type collecting machine that winds up with a take-up machine 35.

〔Effect of the invention〕

As is clear from the above explanation, this invention allows optical fibers to be connected at low tension, and the tension between the supply and the dancer is necessarily low due to the aggregated tension, so there is no strain on the fiber and no external factors are applied to the fiber. If there is a change in the tension of the dancer, it can be easily detected by the movement of the dancer. or,
In this collecting machine, the dancers for controlling the tension of the fibers of each bobbin are placed all together right in front of the collecting point, so that the length of each fiber is the same distance and the collective tension can be made equal. Furthermore, since the fibers are twisted uniformly in both the supply bobbin part and the part of the dancer, it is possible to completely untwist the fibers with a stable, low and constant tension.
