Description

[Detailed description of the invention]

The present invention relates to a ring twisting yarn winding method, and more particularly to a ring twisting yarn winding method that utilizes a ring and a traveler and improves the traveler used to impart twist by rotating a spindle. Traditionally, travelers installed in the twisting section of ring-type draw-twisting machines, twisting machines, spinning machines, etc. have been used to receive the tension of the yarn, so they have an appropriate weight depending on the tension of the yarn. As the yarn to be wound becomes thicker, the tension increases, so it is necessary to increase the weight of the traveler used. However, as the weight of the traveler increases, the friction between the traveler and the ring increases, making the traveler's running unstable.Also, due to the straining by the traveler, single yarn breaks, loops, etc. cause fuzz. The problem arises of increasing As a result of intensive research to solve this problem, the present inventors installed a plurality of travelers in place of the conventional one traveler with an appropriate weight, and installed threads on all of these travelers. If the yarn is wound in such a way that the yarn is wound in a row, the force that the traveler receives from the yarn is dispersed and the weight of each traveler can be reduced. It has been discovered that the total weight can be made substantially equal to the appropriate weight, and the present invention has been achieved. That is, the present invention provides a traveler that slides on the inner surface of the ring when twisting and winding the yarn onto a bobbin using a ring twisting machine, and uses approximately 1/n (where n is an integer of 2 or more) of the appropriate weight of the traveler. This ring-twisting yarn winding method is characterized in that n travelers each having a weight of The present invention will be described below with reference to the drawings. FIG. 1 is a partial perspective view of the vicinity of a traveler in an embodiment of the present invention, and FIG. 2 is a front view of the portion shown in FIG. 1. In these drawings, 1 is a ring, and the ring 1 has two travelers 2, 2'.
is installed. The shape and dimensions of the travelers 2, 2' are similar to conventional travelers with equal weight to each traveler 2, 2'. The weight of each of the travelers 2, 2' is conventionally determined relative to the thickness of the yarn Y that passes through the travelers 2, 2' and is wound up (when one traveler is installed).
The weight is now 1/2 of the appropriate weight. During winding, the yarn Y passes through the yarn passing portions 3, 3' of the travelers 2, 2' in the direction shown, is wound onto a bobbin (not shown), and is wound onto a bobbin (not shown).
rotates in the four directions of arrows. At this time, Traveler 2,
2' is inclined by θ degrees with respect to the normal line, and the upper ring contact parts 5, 5' and the lower ring contact parts 6, 6' are in contact with the upper and lower parts of the ring 1, respectively, while the travelers 2, 2' are substantially It rotates so as to slide integrally on the inner surface of the ring 1. At the same time, the central portions of the travelers 2, 2' come into contact with the inner circumferential surface of the ring 1 due to the centrifugal force of the traveler rotation. By winding the yarn in this manner, the tension of the yarn Y is distributed and received by the two travelers 2, 2'. Therefore, travelers 2, 2'
can withstand even if the weight of
Since the friction between each traveler 2 or 2' and the ring 11 is reduced, the travel of the travelers 2 or 2' is stabilized, and as a result, the occurrence of yarn fuzz loops is significantly reduced. 250 denier of polyethylene terephthalate/
Table 1 shows the results of a comparison between winding the yarn according to this example and the conventional method when producing a drawn yarn of 48 filaments. Table 2 shows the results of a comparison between winding the yarn according to this example and the conventional method during production.

[Table] From the above results, it can be seen that when the method of the present invention is adopted, the occurrence of fuzz and loops can be significantly reduced. FIG. 3 is a partial perspective view of the vicinity of the traveler in another embodiment of the present invention, and FIG. 4 is a front view of the portion shown in FIG. 3. In this embodiment, three travelers 2, 2', 2'' are installed in the ring 1. The weight of each traveler 2, 2', 2'' passes through the traveler 2, 2', 2''. The weight is 1/3 of the conventional weight (when one traveler is installed) for the thickness of the yarn Y to be wound. The dimensions are similar to those of a conventional traveler, which has the same weight as each of the travelers 2, 2', 2''. During winding, the yarn Y passes through the yarn passing portions 3, 3 of the travelers 2, 2', 2''. 3', 3'' in the direction shown in the figure and is wound onto a bobbin (not shown), and the travelers 2, 2', 2'' rotate in the direction of arrow 4. At this time, the travelers 2, 2', 2'' are inclined by θ degrees with respect to the normal line, and the upper ring contact portions 5, 5', 5'' and the lower ring contact portions 6, 6', 6'' are the upper part of the ring 1, respectively. and the lower part of the traveler 2, 2',
2'' rotates so as to slide substantially integrally on the inner surface of the ring 1, and at this time, the center portions of the travelers 2, 2', and 2'' move against the ring 1 due to the centrifugal force of the traveler rotation.
makes contact with the inner circumferential surface of the By winding the yarn in this manner, the tension of the yarn Y is distributed and received by the three travelers 2, 2', 2'', and therefore the tension of the yarn Y is distributed even more than in the case of the first embodiment. 2, 2', 2'', and the friction between each traveler 2, 2' or 2'' and the ring 1 is reduced.
2', 2'' is stabilized, and the occurrence of fuzz on the yarn is further significantly reduced. It goes without saying that the rotation direction etc. are not limited to those shown in the above embodiments.In the present invention, the thicker the yarn to be wound, the more remarkable the effect can be obtained. If the ring is 150 denier or larger, it is significantly advantageous to have two or more travelers in the ring.You can increase the number of travelers to three or more if necessary, but the number of travelers cannot be increased too much. If this occurs, problems such as difficulty in threading occur, so it is usually preferable to limit the number of travelers to about 2 to 3. As detailed above, in the present invention, a plurality of travelers are installed, and Since the weight of each traveler is reduced, the friction between the traveler and the ring is reduced, the traveling of the traveler becomes stable, and the occurrence of fuzz on the yarn can be significantly reduced.
