Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes the rotational force of the ring Δ-1 to perform the anti-seating action. This is related to the improvement of

For spinning rings, dust prevention and exclusion agricultural mechanisms are essential to prevent the rotation of the ring from being hindered by wind dust, which is unique to spinning factories. (In order to avoid the complex structure and cost increase due to the use of 0i, a passive rotating ring with a relatively simple dust-exhaust mechanism was proposed earlier in the Japanese Patent Publication No. 54-15.
There were no other publications other than Publication No. 984. However, the structure of the one published in this publication was somewhat complicated and required many parts with high precision, making it expensive and requiring mass production of one unit.Therefore, it was limited by the application, and it was difficult to use cotton and short fiber mixtures, etc. It lacked versatility for low-cost applications. Furthermore, in the above-mentioned publication, a triangular annular protrusion with a triangular cross-section was inserted into a tapered groove with a triangular cross-section recessed on the same surface to form a sliding shaft bearing. Bulky cotton dust is discharged to the upper and lower end openings of the larger diameter ring by the taper on the outer periphery of the ring rotating body and the dust exhaust mechanism of the diagonal groove, but it is generated from fine short fibers, oil, etc. With fine particles of dust,
Items that are not bulkier than this taper part gap are not subjected to the squeezing friction due to the taper between the outer circumference of the ring rotating body and the inner surface of the holder, and are warped due to the centrifugal action, causing triangular sliding i< and slight movement. The particles gathered in the gap at the tip of the large-diameter triangular groove and were partially deposited and compressed in the triangular concave groove, forming a felt-like noisy frictional resistor, which caused IMI damage to the rotation of the ring. In addition, in the rotating ring of the above-mentioned publication, the triangular sliding shaft bearing part is located at the center of the inner peripheral surface of the holder, and the gap from the triangular sliding joint to the upper dust exhaust opening is long and has a steep angle. Because there were two bends, dust could easily get in. - The fluff dust in the gap between the L parts was piled up on the bends and was pressurized, turning into felt, which was one of the causes of cotton clogging during dust removal. Furthermore, since it is a rotating body whose fulcrum is the contact point of the traveler on the ring flange of the rotating body and the point of force (~, 111II bearing triangular sliding contact point), the distance between the fulcrum and the point of force is long.
There were also cases in which the rotating body slumped and twisted, causing the outer periphery of the lower end of the ring rotating body to come into contact with the inner periphery of the F end of the holder, producing sparks and sparks.

The present invention improves and compensates for the various defects in coffin construction discovered from actual use, and makes it possible to improve the structure of the coffin. It is designed to simplify the width and achieve wide versatility due to the cost I/down.The explanation is as follows: (1) In the support structure, the inner diameter is 4 mm, the outer diameter is Φ, and the thickness is The triangular bearing part, which was unsuitable for mass production due to the crystal precision price, was removed because it required contact or proper play on the surface of the ring, and the ring rotating body and the holder fixed to the ring rail were directly rotated. By freely aligning the loose parts, the structure was simplified, and the number of parts was reduced to reduce costs. That is, in Fig. 2, the bearing part A
IJ consists of the flange rotor 1a and the lower rotor 1b.
k, a cross section of 1-shaped chi in the center of the outer periphery of the ring rotating body 1.
・A --shaped triangular groove is provided, and the groove is cooled from the center to the upper and lower ends to make it larger in diameter, and the formed triangular grooves are moved relative to each other with minute gaps a1 and a2. The ring rotating body 1 is rotatably engaged and supported by the curved/V-shaped taper annular triangular mark on the inner circumferential surface of the holder 2, and receives torque from the centrifugal force flowing to the traveler 10. The ring rotating body 1 was designed to be able to smoothly rotate I+]1. The sliding flange of the above-mentioned publication had a triangular shape protruding toward the side 1, but this dome bearing part reversed the unevenness and turned upward toward the outer diameter.
Since it has a V-shaped tapered shaft bearing that opens downward, even fine dust can be extracted toward both ends of the bottom by the taper f + 9 structure, so Asahi cotton dust accumulates in the triangular bearing. No harm will occur due to ring rotation.

Furthermore, the removal of the sliding flange 7 reduces the number of locations where xbV\i+ occurs, and on the other hand, the shaft bearing part of the above publication was located at the center of the holder, but in the present invention, it is located on the inner peripheral surface of the holder 2. The one-character taper annular triangular coin protruding from the top of the holder 2 was placed (~meu1) because the fulcrum of the bearing was brought close to the force point of the traveler contact flange, so that the ring rotating body 1 would not be affected by spinning tension or rotational speed changes. Even when the vector changes in the diametrical direction of the lower pump, it does not wobble or oscillate, and the holder 2 is free-5- oil with a low friction coefficient. Since it is made of dipolyamide-imide or filler-containing tetrafluoride resin, etc., it has a structure that allows the ring rotating body to rotate smoothly 10 times even when subjected to minute torque.

(2) In the dust removal mechanism of the present invention, a protrusion value 5 with a gentle slope is formed from the bearing part A to the upper part of the flange rotor 1a, and the outer periphery of the lower rotor 1b is gradually increased in diameter from the bearing part to the lower end circumference. The ring rotating body 1 has a tapered structure that opens vertically toward the diameter from the center of the V-shaped bearing groove in the middle part of the outer periphery to both the upper and lower ends. The inner circumferential surface of the holder 2, which is opposed to the ring rotating body 1, is connected between the upper protruding rear surface of the flange rotor 1a and the tapered outer circumferential direction of the lower rotor 1b. Engage with the ring rotating body 1 with a gap wider than that of the actual shaft bearing to rotatably support it, and create a sharp bending point from the center of the bearing to the gap at the neck of the opening at both upper and lower ends. 6. In other words, the distance 1) from the shaft bearing part to the upper opening O, where air dust easily enters and is easily discharged, causing air dust clogging, has been shortened and smoothed. A large number of oblique grooves C1 are carved on the entire oblique circumference of the rear surface of the four protruding parts of the flange rotor 1a according to the rotational direction of the ring, so that the structure has a sufficient dust removal effect even when the ring rotates at a low speed of 1c1.1. is. In addition, the lower gap b2, which has good dust removal efficiency, has a gentle taper shape with an 11th large diameter from the bearing part toward the lower end, and follows the ring rotation direction along the entire tapered outer circumference ff1 of the lower rotor 1b. A spiral groove C2 is carved to increase the effect of natural dust fall, taper squeezing effect, and physical friction caused by the spiral groove 02 to discharge dust from the internal gap to the circumferential opening.

As described above, the improvement of the dust removal mechanism is that -F
-F toward the outer diameter of all the air gaps at the openings at both lower ends
By eliminating the downwardly-opening taper shape and steeply bent part, the dust that has entered the nitrogen gap is compressed and rotated by the two inner and outer tapers, resulting in a larger diameter due to the centrifugal action. - While the dust is being moved and discharged to the upper and both end peripheries, there is no place for dust to accumulate or accumulate as in the above-mentioned publication, and the dust can be removed more completely.

The dust ejected from the opening part of the father part is caused by the air flow ejected to the outer periphery due to the ring rotation of the diagonal grooves 3' carved on the inner wall of the dust cover 3 attached to the upper outer periphery of the flange rotor 1a. At the same time, it is discharged and removed from the ring by physical centrifugal action.

Also, this dust cover 3 covers the flange rotor la and the upper opening of the holder 2, and is slightly attached to the edge of the upper outer plate of the flange rotor 1a, so that it cannot be used with a snail wire or traveler 10.・The role of the dust cover is to prevent fine particles such as short fibers and oil agents that fall from the spun yarn 11 from entering the space inside the ring 1, and when the machine is stopped, the outer periphery of the soft elastic thin-walled dust cover protects the holder 2. This dust cover has a braking effect of 1, which also acts as a brake that comes into contact with the upper edge circumference and stops the rotation of the ring rotating body 1 before the spindle stops rotating. In order to increase the rotation speed of the dust cover 3, a large number of oblique blades 5 are provided at equal intervals on the outer periphery 1 of the dust cover 3, and by utilizing the air resistance caused by the rotation of the ring, a walking force is generated. As the downward force increases due to divinization, the ring rotating body 1 is pulled down to apply friction pressure to the bearing part, and the tip periphery of the dust cover 3 is lowered to contact friction with the outer periphery of the boulder 2 to perform a braking action. A metal ring 7 is inserted into the inner connecting part of a soft elastic (for example, synthetic rubber or synthetic resin) ring body surrounded by a ring body on the side, and the rigidity of this metal ring press-fits and fixes it to the lower peripheral edge of the lower rotor 1b, and the ring rotating body 1 and The end rope of the integrated L-shaped brake ring 6 is a brake embedded plate 6b that opens slightly outward and downward from the part temporarily attached to the ring rotating body 1.
Tonanashi, when ring rotating body 1 is rotating at low and medium speeds, holder 2
When the lower end of the brake plate 6b is brought into contact with the lower end of the holder 2 with an appropriate gap, and gradually rotates at a high speed, the circumference of the tip of the brake buried plate 6b becomes long enough due to the action of centrifugal force, and it comes into contact with the lower end of the holder 2. Initially, when the rotation becomes faster and exceeds a certain limit (approximately 5.00 ORPM in the experiment), the tip periphery of the brake effect 6b rises horizontally like a valve and applies strong frictional pressure to the lower end of the holder 2. In addition, it acts to lower the ring rotating body 1, provides contact friction to the bearing part, and acts as a brake to control the speeding up of the rotor, and serves to prevent the temporary occurrence of snarl (when several units are stopped). .

In addition, a large number of diagonal grooves 6' are carved on the inner surface of the brake buried plate 6bVCn according to the rotational direction of the ring, and as the ring rotating body 1 rotates at the Nakajima speed, the large number of diagonal grooves 6' cause the grooves to flow out of the ring. Generate air flow to create ring gaps a2, b2
It functions to release dust discharged from the bottom end of the ring to the outside of the ring.

As explained above, the present invention simplifies the structure by reducing the number of parts for the bearing and dust evacuation mechanism, and also solves the problems of the bearing/exhaust function. 1
(2) Does not cause high vibration or oscillation in any rotation at low or high speeds, (8) Rotates smoothly even at low ε torque (low PV value), ( 4) It has a simple structure, excellent mass production, low cost, and is highly versatile.
It can be applied to all types of cotton and blended staple fibers, and can improve productivity, yarn quality, labor saving, and energy saving effects for a wide range of products from fine count to thick yarn count.
