Abstract

PURPOSE:The pressurized air sent into the hollow shaft of the inner rotor is lead into the spinning chamber in the tangential direction to peel off the sliver formed on the inner surface of the outer rotor and to make it into a yarn, thus producing good-quality spun yarn with high fiber parallelism. CONSTITUTION:The pressurized air P is sent from the one end of the hollow shaft 11 of the inner rotor 10 and changed its direction by the first turning face 17 in the plag 16 to run through the hole 18 and the guide in the inner rotor 10 into the spinning chamber in the tangential direction to the inner surface. The air is converted into a turbulence X to suck the sliver F2 on the inner surface 8a of the outer rotor 8 just as peeling it off. At the same time, the differential rotation of the inner rotor itself to the outer rotor 8 continues to suck the yarn and spin the yarn.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for spinning high-quality spun yarn. More preferably, a spinning method that belongs to the public funds of open-end spinning and includes the spinning principle of high-quality spun yarn;
and regarding equipment. The conventionally well-known open-end spinning system originally had a high spinning speed, and also had the ability to directly wind the spun yarn into a large package such as cheese or corn to perform the first rewinding process. However, since it was impossible to draft the sliver that could be formed inside the rotor, the sliver could be left as it is without being drafted. As I was pulling it out, it was forming a thread. Therefore, the degree of meandering of each single fiber constituting the yarn is poor, and the tensile strength of the spun yarn is poor.

In addition, drawbacks such as difficulty in spinning fine yarn that exceeds the JOI hand have been pointed out, and with the exception of some applications,
In general, it seems that the situation is still difficult to employ.

In addition, ring spinning, which is currently in practical use,
The system is slow. Although some drawbacks have been pointed out, such as the outer layer of the yarn being damaged by silapella, in comparison with the yarn spun by the open-end spinning system described above, The reality is that it is only being put into practical use.

The inventor of the present application, based on the opinion that the existing Subininda fist system has the above-mentioned actual situation, - with the intention of developing a new spinning method to replace these, #TokenKabuto As a result, in order to produce high-quality spun yarn.

First of all, it is essential to utilize an air vortex with sensitive guiding properties for the fibers. I thought.

The present invention, by utilizing the air vortex,
This not only made it possible to spin high-quality yarn, which was the original goal of Shaochu, but also went further and made it possible to construct an automatic spinning machine. More specifically, it has both an inner and an outer rotor that rotate once in the direction of rotation with a required degree of differential, and the air flow is based on the centrifugal force caused by the rotation of the outer rotor.

The suction force based on the flow separately sucks single fibers from the fiber group, collects and focuses them on the truncated cone-shaped inner wall surface of the outer layer, and carves a sliver. The spinning unit is a spinning unit in which the sliver formed on the inner wall surface is separated from the inner wall surface by the suction force and swirling force of the air vortex flow, and at the same time, the sliver is swirled and formed into a yarn. and a means for supplying a fiber group, such as a sliver produced by a card machine, a drawing machine, etc., or a 7-lease sent out from a drafting device for drafting the sliver, and a spinning method. The principle of spinning high-quality spun yarn can be achieved by installing it between the pulling means for pulling out the yarn and coordinating the respective functions of these means and the spinning machine. We have constructed a spinning method including this method, and an apparatus for carrying out the method.

Next, this spinning method and each element constituting the apparatus will be explained with reference to embodiments shown in the drawings with S. 7th
In the cabinet, 1 and 2 are fiber groups 12, for example, slivers produced by a card-2 drawing machine, or 7 leases sent out from a drafting device for drafting the sliver, or a combing device. The means for supplying the combed fibers taken out from 11 means the above-mentioned spinning et.

That is, this spinning unit U contains the above-mentioned fiber group! The supply means 1 and 2 also automatically suck the fiber group sent out,
This is to be made into a thread form, with a truncated conical inner wall surface 8. The support shaft 9 of the outer a-ta 8 and the hollow support shaft 11 of the inner sorter 1o are combined concentrically, and both support shafts are applied by any means or by the attraction force of the permanent magnet N8 to the stacked steel plate ring 1. As a result, each of the stepped pulleys 6, which has a larger diameter, can be easily pressed against the stepped pulley 6, or between the stepped pulleys B and the pair of stepped pulleys. The wheel body 11' that landed on the shaft and 11
On the other hand, it performs differential rotation based on the difference in diameter.

By the flow of air based on the centrifugal force accompanying the rotation of the outer quarter 8, the fiber group 1 sent out from the fiber group supplying means 1φ2 described above is sucked into the fiber suction tube 7, and the fiber group 1 is sucked into the fiber suction tube 7. It includes a fiber suction means T@) for discharging the fibers as shown in FIG. Air vortex generation means 1 for introducing compressed air P from one end of the hollow support shaft 11 and converting it into an air vortex in the spinning 1 [16] of the inner rotor. It's shaped.

Therefore, at the same time as the outer rotor 8 starts and rotates, a suction force is generated in the fiber suction tube T of the test-spinning et, and the fiber group 1 drawn out from the fiber group supply means 1 and 2 is transported through the delicate suction tube γ. The fibers are sucked into the fiber group by the strong suction force, and the sliver is drawn into the largest diameter part of the fiber group! Note that compressed air P is fed from one end of the hollow support shaft 11 of the inner pipe 10, and the compressed air is Air hole 18 provided in the inner tank 1o. The air then enters the inner wall of the spinning chamber tangentially through the air guide groove 19, where it is converted into an air vortex X to be swirled.

This air vortex X swirls around the outer layer of the inner tube 21 and flows through the tube end 21. Grab the inner and destroy the hollow shaft of the evening 1
10 axis, and generates a suction force in the inner tube 21, and at the same time, due to the suction force, the inner tube is formed on the inner wall surface of the outer quarter from the outward opening end 26 of the inner tube. The sliver R8 that is being spun is sucked in and given a swirl to form a yarn, and this air vortex flow It is the presence of this element that makes it possible to spin such high-quality spun yarn for the first time.

That is, this spinning principle utilizes the above-mentioned sensitive fiber-inducing properties of the air vortex, and the outward opening end 26 of the inner tube 21 is opened against the inner wall surface 1. , and the sliver ν1 that grows on the inner wall surface is sucked so as to be separated by the suction action of the air vortex It should be transformed into a filament.

In other words, there is a sliver on the inner wall surface S1 of the outer rotor! As soon as , is formed, the air vortex X swirls around the outside of the inner tube 21, and the end of the tube.

Due to the suction force on the outward opening end 26 generated based on the vortex flow, the outward entrance end suctions the sliver F2 into the inner pipe as if chasing it, and the pipe end 211 When the thread is exposed from the thread, it must be twisted and transformed into a thread.If it is lightning resistant, the thread spun by an automatic spinning means that incorporates this spinning principle will be , Sliver! The free end of each fiber connected to , is sucked by the air vortex X! 1. Under the influence of the turning force, the posture is corrected in a stretching manner, and the parallelism of each fiber is inevitably improved, and at the same time, the fibers are focused in a narrow squeeze and form a thread while turning. Therefore, the yarn spun by automatic spinning means that incorporates this spinning principle can be said to be a high-quality spun yarn that is superior in both aspects to its texture. The yarn end Y of the spun yarn is further guided by the exhaust of the air vortex, and the yarn end Y of the yarn spun by

From the tip of the child, it passes through the umbrella guide pipe 26 and is molded into the upper and lower plates of the output means $04.

Therefore, this yarn end Y is immediately automatically gripped by both the upper and lower plates and is applied at a predetermined speed*j1 o'clock Lt

The sliver 1□, which can be stretched upward, is drawn.

A predetermined twist is applied based on the rotation of the inner stomach and the yarn, and the yarn is formed into a yarn, which is further wound into any desired bunnage such as cheese or corn to complete the entire process.

In the future, if such automatic spinning means were to be implemented, it would bring about significant labor savings in spinning factories, and at the same time it would solve the problems caused by wage disparities.
