[Industrial applications]

 The present invention relates to a winding device represented by, for example, a double twister for twisting yarn in spinning, and more specifically, to reduce air resistance of a ballooning yarn formed when winding a yarn and to perform stable winding. The present invention relates to a winding device that can be used. In the present specification, the case of a double twister will be described as a representative example, but the application of the present invention can be applied to all yarn winding of natural fibers and synthetic fibers.

[Prior Art]

 FIG. 5 is an explanatory view showing an example of a double twister. This device is composed of a part for applying twist to untwisted yarn and a guide part for winding the twisted yarn on the package 2, and these parts are separated by the snare wire 15 as a boundary. ..

That is, the portion to which the above-mentioned twist is applied is a protective frame 14 for accommodating the untwisted yarn package 1, a flyer 12 which horizontally rotates above the protective frame 14, and a twisted yarn package at the center of the flyer 12. It is composed of a hollow spindle 11 arranged so as to penetrate the bobbin, and a rotor that rotates under the protective frame 14. The untwisted yarn 1a unwound from the untwisted yarn package 1 is introduced through a flyer 12 into a rotating hollow spindle 11 to impart twist, and is guided by a rotating rotor 13 via a lower part of the spindle. It is guided to the snail wire 15 while forming the ballooning portion 1b, and further twisted therein.

In the winding guide portion, the twisting yarn package 2 is provided opposite to the friction roller 16, and a traverse guide movable in the direction of the arrow is arranged downstream of the feed roller 17B. Therefore, the twisted yarn 1c that has passed through the snail wire 15 is regularly wound on the twisted yarn package 2 by the traverse guide 17 via the feed roller 17B.

[Problems to be solved by the device]

 When twisting with the double twister, the yarn forming the ballooning portion 1b is rotated at a high speed, so the air resistance becomes very large, and the loss due to this resistance is a great waste of rotational energy. At the ballooning part, the surrounding air is entrained to generate a turbulent air flow, and the turbulent air flow may adversely affect the yarn rotation.

In order to prevent airflow fluctuations in the ballooning portion 1b of the adjacent double twister, it has been considered to provide a shield plate 20 between the double twisters, but the influence of turbulent airflow generated by itself can be eliminated. However, the effect of suppressing fluctuations in the air flow from the outside was not so great.

Therefore, the present inventor has completed the present invention for the purpose of providing a yarn device such as a double twister capable of reducing air resistance in a rotary yarn forming a ballooning and performing stable twisting yarn.

[0008]

[Means for Solving the Problems]

 The present invention, which has achieved the above object, introduces a yarn into a hollow spindle through a rotating flyer, and further forms a balloon on the outside of a protective frame by a rotor through a hollow spindle to form a yarn. In a winding device for winding a package, an outer frame is arranged along the outer periphery of the ballooning, and a concave portion that forms a resistance against an air flow is formed on a wall surface of the outer frame. It is what you do.

[0009]

[Action and Example]

 FIG. 1 is an explanatory view showing a typical embodiment of the present invention. The basic structure of the double twister is the same as the conventional example shown in FIG. 5, and the characteristic structure of the present invention is that of the ballooning portion 1b. The outer frame body 14B is fixedly provided on the outside so as to surround the ballooning portion 1b. Further, a large number of recesses D are formed on the wall surface of the outer frame body 14B.

That is, by providing the outer frame body 14B, it is possible to prevent turbulent airflow and the like from entering the ballooning portion forming side from the outside, so that the ballooning portion 1b can maintain a stable state. Further, due to the rotation of the yarn forming the ballooning portion 1b, a rotating airflow is formed on the outer side thereof in the same direction as the yarn rotating direction. However, due to the concave portion D on the inner wall surface of the outer frame 14B, This rotating airflow forms a stable air layer C that stops due to resistance, prevents the following airflow from being stably formed in the circumferential direction and prevents turbulent airflow, and the yarn rotates smoothly at high speed to reduce rotation loss. To do.

A concave portion D similar to the outer frame body 14B is formed on the outer wall surface of the protective frame 14A corresponding to the inner portion of the ballooning portion 1b so as not to disturb the rotating airflow formed inside the ballooning portion 1b. It is preferable to keep it like this. Further, it is preferable to form an openable / closable door portion 14B ₁ on the outer frame body 14B through a hinge 18 as shown in FIG. 2, so that the replacement work of the non-twisted yarn package 1 will not be hindered. You can do what you do.

In the illustrated example, the shape of the outer frame body 14B is a vase shape corresponding to the shape of the ballooning portion 1b. However, the present invention is not limited to this, and a penetration type cylindrical shape or a conical shape is used. It may be trapezoidal or the like, and the shape of the concave portion D is not limited to the circular shape shown in FIG. 3 (a) and has an oval or polygonal contour as shown in (b) and (c). Further, the arrangement pattern may be arranged in the circumferential direction, the longitudinal direction or the horizontal direction as shown in FIG. 4 (b), or may be randomly arranged as shown in (c). It may be any combination, and as shown in (a) and (c), those having different contour sizes may be combined, or those having different contour shapes may be combined. The present invention is not limited to the double twister shown in the above example, but can be applied to other spinning machines forming a ballooning portion, such as a ring spinning machine and a cap spinning machine.

[0013]

[Effect of the Invention] Since the present invention is configured as described above, the yarn forming the ballooning portion can perform stable high-speed rotation with little resistance loss, and the winding energy loss is small. It became possible to do.
