の構造に関するものである。Description: BACKGROUND OF THE INVENTION (Industrial application field) The present invention relates to a structure of a yarn drawing section in a rotor type open-end spinning machine, and more particularly, to a twist stop for accelerating twisting of a yarn being drawn from inside a rotor. The present invention relates to a structure of a thread drawer provided with a piece.

されるに至っている。(Conventional technology) In a rotor-type open-end spinning machine, in order to continuously spin yarn while forming yarn from a rotor rotating at high speed, it is necessary to separate the yarn taken off the inner peripheral surface of the rotor. It is necessary that a certain amount of twist is applied. If the number of twists is too small, yarn breakage is likely to occur, and continuous spinning of yarn cannot be expected. Therefore, in order to propagate the twist to the yarn being drawn (hereinafter simply referred to as a yarn end) in the rotor, a yarn drawing tube as disclosed in Japanese Utility Model Laid-Open No. 50-24825 or Japanese Patent Laid-Open No. 51-38551, for example. The method of promoting the rolling of the yarn at the entrance of the yarn and causing the twist to spread to the yarn end side by the false twisting action by the rolling has been adopted.

以上にも達している近年の超高速オープンエンド精紡機
においては所期の撚効果を期待することができない。However, the twisting action by the above-mentioned rolling of the yarn is such that as the rotation speed of the rotor and the drawing speed of the yarn increase, the rolling efficiency of the yarn decreases, and the rotational speed of the rotor becomes 80,000 / rpm.
In the recent ultra-high-speed open-end spinning machines that have reached the above, the desired twisting effect cannot be expected.

伝播を促進する手段が採られている。For this reason, in the ultra-high-speed open-end spinning machine as described above, as shown in Japanese Patent Application Laid-Open No. 62-76031, two turning parts are arranged in a yarn drawing pipe and the turning part is provided at the turning part. Means to prevent the axial rotation of the yarn and promote the propagation of true twist at the yarn end.

立ちが著しく多くなる。(Problems to be solved by the invention) However, according to the twist propagation means to the yarn end by the device described in the above-mentioned Japanese Patent Application Laid-Open No. 62-276031, the rotation of the rotor is caused by the two turning portions in the drawer tube. The true twist is prevented from directly spreading to the pull-out roller side, and since the turning portion performs a kind of twisting action, it is possible to transmit a lot of twists toward the yarn end. Since the two turning portions are formed by the projections, the yarn passing through the turning portions is subjected to strong friction, and the fluff on the yarn surface is significantly increased.

提供するものである。SUMMARY OF THE INVENTION The present invention provides a structure of a yarn pull-out section in an open-end spinning machine having a twisting piece that promotes twisting of a yarn being drawn in a rotor without causing fluff on the spun yarn. .

る。(Means for Solving the Problems) As shown in FIG. 1, the structure of the yarn pull-out portion in the present invention is an inlet of a yarn pull-out tube (3) for extracting a yarn (2) from the inside of a rotor (1). A twisting piece (6) provided with a drill-shaped spiral guide groove (5) as shown in FIG. 2 is provided in the cylindrical portion of the navel tube (4) provided in the above.

チの0.5〜1.2倍である。The outer diameter of the twisting piece (6) to be applied is slightly larger than the inner diameter of the opening (11) at the entrance (7) of the navel tube (4), and the spiral pitch of the guide groove (5) is 12 to 18 mm. The twist angle (θ) is about 20 ° to 50 °. This torsion angle (θ) is 20
゜ In the cases below, the frictional resistance given to the yarn becomes small and the twisting effect decreases, and when it is more than 650, the frictional resistance given to the yarn becomes too large and the yarn breaks easily. The length of the spiral guide groove (5) is 0.5 to 1.2 times the spiral pitch of the groove.

せる。(Operation) The yarn (2) drawn from the rotor (1) is twisted along the guide groove (5) in the twisting piece (6) provided in the cylindrical portion of the navel tube (4) and travels. Then, the yarn is pressed against the surface of the guide groove (5) by the yarn pulling tension, thereby increasing the running resistance of the yarn, preventing the yarn from rolling on the surface of the guide groove (5), and moving toward the pull-out roller. This prevents the propagation of twist and promotes the twisting of the yarn (2) being drawn from the twisting piece (6) to the fiber collecting groove (8) of the rotor (1).
