Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn winding device for winding a yarn around a bobbin while traversing it with a guide device.

Conventionally, a tape-like yarn having a flat cross-sectional shape obtained by gathering a plurality of fibers in a bundle, as typified by carbon fiber, has been known. Various winding devices for winding are known (see, for example, Patent Documents 1 and 2).

These winding devices are provided with a guide support portion that reciprocates along the axial direction of the bobbin, and a plurality of guide rollers arranged side by side on the guide support portion in a manner that intersects the running direction. It is traversed by the reciprocating movement of the supporting portion, and is wound up on a bobbin by being sent out while being guided by each guide roller in sequence.

In order to obtain a high-quality package (yarn wound on a bobbin) with a uniform end surface shape and no twist in the wound fiber, the guide roller provided in the guide device is extremely important. In particular, the stabilization of the running position of the yarn in the guide device is directly linked to the shape of the end surface of the package.

At this time, if guide rolls that are gently curved on both sides in the axial direction are used, the running position of the yarn can be stabilized. large-diameter portion) may come into contact with each other and may be twisted.

In recent years, in order to improve the quality of packages, it is demanded that even carbon fibers of 3K or less called small tow be wound in a flat state without being twisted. It is effective to increase the number of guide rollers along the running direction in order to stably run such a thin yarn such as carbon fiber, which has a small contact area with the guide rollers, on the guide device.

However, if the number of guide rollers in the guide device is increased as described above, the running of the yarn in the guide device is stabilized. There was a problem that it took a long time and the work efficiency decreased.

Specifically, as shown in FIG. 7, first, second and third guide rollers 141′ to 143′ are arranged in parallel from the upstream side to the downstream side in the running direction on the guide support portion. In the case of such a device, first, the yarn is gripped with one hand F, and while it is hung on the rear peripheral surface of the first guide roller 141 ′, it is pulled between the first guide roller 141 ′ and the second guide roller 142 ′. After passing through, it is passed between the second guide roller 142' and the third guide roller 143' while hanging on the front side peripheral surface of the second guide roller 142', and finally behind the third guide roller 143'. Threading work is completed by hooking on the side peripheral surface. When passing between the second guide roller 142' and the third guide roller 143' in the second half of this threading operation, the yarn gripped with one hand F was pulled out to the vicinity of the tip of the second guide roller 142'. After that, the yarn is inserted between the second guide roller 142' and the third guide roller 143', but at this time the yarn slips especially from the tip of the second guide roller 142'. there was a case.

Needless to say, when the thread is passed between the second guide roller 142' and the third guide roller 143', the thread is prevented from slipping down from the tip of the second guide roller 142'. It is conceivable to use one hand F to hold down the thread that is hung on the front peripheral surface of the second guide roller 142', but the threading operation using both hands is troublesome and the thread may be inadvertently touched. As a result, unnecessary twists, wrinkles, stains, and breakage may occur.

In particular, since a large number of yarn winding devices are installed at a yarn winding site, a decrease in yarn threading work efficiency greatly affects the yield of products, resulting in a decrease in package production efficiency.
