Description

[Detailed Description of the Invention] The present invention relates to an improvement of a balloon control ring for spinning and twisting used for spinning and twisting yarn, tire cord twisting yarn, and the like.

Conventionally, a balloon control ring 1 used in spinning has been formed by welding a cylindrical ring body 2 and a mounting member 3 to a machine stand, as shown in FIGS. 1A and 1B.

The attachment member 3 is provided with an oil supply tank 4, and oil is supplied from the oil supply tank 4 to the inner peripheral surface of the balloon control ring 1 through an oil guide port 6 formed in the cylindrical ring body 2 by an oil guide system 5. was.

Since the above balloon control 1 has a flat top surface, flies floating in the factory accumulate on the top surface, and the collected fly clumps get caught up in the thread as the thread passes, causing slub yarn generation. There is a drawback, and the oil is not present in the oil tank 4 and the mounting member 3.
The problem was that it oozed out from between the parts and stained the area around the machine and the floor.

Furthermore, since the oil guide port is only provided in a part of the ring body, the oil does not flow well to the inner circumferential surface of the ring body.
This caused yarn fluff, melted yarn, and yarn breakage.

The present invention has been made to eliminate the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 2A and 2B, the balloon control ring 7 is composed of a cylindrical ring body 8 and a mounting member 9.

The attachment member 9 is integrally fixed to the cylindrical ring body 8 by welding, adhesive, or other joining means.

The outer circumferential surface of the cylindrical ring body 8 is constituted by a slope 10 that slopes from above toward the outside and below, and an oil storage tank 11 is formed on the slope 10 over substantially the entire circumference thereof.

Also, at the bottom of the oil storage tank 11, an oil retaining substance 1 made of felt, sponge, polyurethane foam, etc.
2 is arranged, and an oil filler port 1 is provided at the opening of the oil storage tank 11.
A lid 14 having one to several locations of 3 is disposed.

Further, the cylindrical ring body 8 is formed using a sintered metal using pure iron powder or alloy steel powder, or a metal such as case hardened steel or carbon tool steel. Oil leakage is prevented by sealing the outer circumferential surface and the lower surface of the ring, excluding the inner circumferential surface where it is necessary (i.e., the part in contact with the thread). A plurality of oil supply holes penetrating toward the inner peripheral surface of the body 8 are provided at approximately equal intervals. Of course, in this case, it is more effective to arrange an oil supply line in the oil supply hole.

Furthermore, the cylindrical ring body 8 has an axis extending from the axis passing through the center of the cylindrical ring body 8 and approximately the center of the attachment part 9 on the right side (in the case of S twist) or the left side (in the case of Z twist) when viewed from the front. At a position where the distance A is 0.35B to 0.45B with respect to the radius B of the outer periphery of the cylindrical ring body 8, the thread intersects with the outer periphery in the sliding direction of the thread (arrow C),
The yarn guiding port 15 is formed so as to be inclined at an angle α of 5° to 15°. (The drawing shows S twist) The yarn guide port 15 is provided at a position substantially opposite to the position where the attachment part 9 is attached, and the interval T is 0.5
3 mm, but 1 mm to 2 mm is preferable in terms of use.

Since the balloon control ring for spinning and twisting of the present invention has the above structure, there is no lubricant seepage or leakage to unnecessary parts, and contamination around the machine stand and on the floor is prevented. Even if fly particles generated after the front roller nip point attach to the top surface of the balloon control ring, they fall off very easily, reducing cleaning man-hours, reducing the generation of slub yarn, and increasing the production of high-quality yarn. It becomes possible.

In addition, it has a large number of oil draining mechanisms on the inner peripheral surface that comes into contact with the thread, and an oil storage tank is formed around the entire circumference.
The oil agent percolates uniformly over the entire inner circumferential surface of the balloon control ring, and the practical effects are great, such as the generation of fluff and molten threads being greatly reduced and the number of thread breakages reduced.
