Description

[Detailed description of the invention] Improvement of ring spinning machine The present invention relates to the production of yarn or similar materials, and in particular to the consolidation and binding of the fibers that make up the yarn. The present invention relates to a method and apparatus for producing conventional yarn, in which the main means for producing yarn is twisting. . Yarns can be formed from stable fibers or continuous filaments, In the former case, frictional force is generated between the fibers (the tensile strength of the yarn depends on this frictional force). Twisting is mainly used to make the wires stay together. The threads are two pre-spun threads or The above single yarns are twisted together to form a plied yarn or a cable yarn. It can also be formed by

The most common method of making yarn from stable fibers is generally a ring frame using a ring spinning machine known as Ring spinning method is completely twisted of untwisted or lightly twisted sliver, roving or roving The process of supplying an aggregate of stable fibers such as sliver, rovin The process of drafting the roving or roving in a drafting zone, in which the drawn strand is controlled. This strand is fed at a speed controlled by the rotation of the spindle. The process of twisting and the yarn thus spun into a ring and traveler mechanism The process of winding the yarn onto a yarn storage package mounted on a rotating spindle while guiding the yarn. are carried out at the same time.

In a ring spinning machine, the ring is mounted on a movable plate concentrically with the axis of the spindle. Ru. During the spinning operation, the movable plate is reciprocated parallel to the spindle. That is, movable The plate moves parallel to the spindle in one direction, consisting of a yarn storage package. It forms a thread. The thread runs freely around the ring. It is inserted into the bellow (which by its shape is constrained to the ring). Travel la is tangent to the circle of the ring at a rotational frequency lower than that of the spindle. It runs on the ring due to the tension of the thread, which has a component acting in the direction. Traveler's Its primary function is to guide and control the movement of yarn to the yarn storage package on the spindle. The reciprocating movement of the ring rail allows for regular and convenient packaging. This is what forms the ji.

The rotational speed of the traveler changes continuously during the spinning cycle, and its instantaneous speed is The rotational speed of the thread, the diameter of the yarn storage package at the winding point and the drafted Depends on the feed rate of the strands.

Frictional contact minimizes drag on the traveler and localized heating It is common to lubricate the ring surface with oil or a similar lubricant to minimize It is. Otherwise, prevent overheating and keep the traveler and ring suitable and practical. To obtain longevity, there is a limit to the speed of the traveler on the ring. this reality In the case of travelers formed from steel, the limitations are substantially related to the diameter of the ring. generally linear velocity of 30 meters per second, and the traveler made of nylon In this case, the speed is 37 meters per second. And the speed limit of this traveler is This is the main cause of production rate limitations for

Although ring and traveler mechanisms are generally effective for their intended purpose, they The rubber wears at the point of contact with the ring and the point of contact with the thread and must therefore be replaced regularly. The major disadvantage is that the traveler has to be Since you have to make a selection, if the number changes, you also have to change the traveler. There is also a drawback.

One conventional method to overcome some of these limitations of ring and traveler mechanisms and devices that make the ring itself rotatable by means of bearings or actively drive the traveler to reduce the relative speed of the traveler to the ring, or The absolute speed of the traveler is increased by increasing the rotation speed, and the yarn production speed is increased by that amount. The aim is to increase the However, this type of device is relatively expensive to manufacture. Moreover, power consumption during operation is large, and therefore it is not very desirable from an industrial perspective. This format An example of this technology is the European patents E and P of Marchioro et al. , No. 225660, in which a freely sliding traveler is connected to a fixed Various rotating rings are disclosed that replace the thread guide. This mechanism The diameter of the ring is small, the power consumption is low, and the tension of the thread in the balloon is low, but the thread It also has the disadvantage that insertion and dotting of the full tube package is complicated.

The principle of another way to overcome the drawbacks of ring and traveler mechanisms was first It was proposed in the 1828 British patent by Thorpe, and later by T. Homas and Wood, U.S. Pat. No. 3,172,249. was suggested. According to this proposal, a ring is supported in a geostationary orbit and This allows the ring to rotate and hang freely. This orbit is such that the ring A wall that rotates and rolls in its own plane, and a ring that rotates in its own plane. and a flange for guiding the ring. And the rings and orbits are The dimensions should be such that there is a gap between the outer circumference of the ring and the inner circumference of the raceway for the thread to pass through. It will be done. In operation, the ring is driven by the tension of the thread, causing the thread balloon to rotate. It rolls along the track as it moves. This mechanism does not require a traveler and is It has the advantage that the energy required to drive the motor is also small. However, to The above-mentioned mechanism by Kuss and Wood is particularly useful when stable fibers are spun. Fiber debris, dust, and oily substances or top coats on the threads can accumulate and cause damage to the track. There is a drawback that the build-up is trapped in the canal and the movement of the ring takes until thread breakage occurs. interfere with production.

Other drawbacks of the Tokes and Wood mechanism are that the ring reenters the orbit and that the Frictional drag occurs between the ring and the raceway at the point where the ring exits the raceway. Ru. The instantaneous force exerted on the ring due to the tension of the thread acts at the point of contact between the thread and the ring. can be decomposed into three mutually perpendicular forces. tangential to the ring One component of the force tries to slide the thread around the circumference of the ring and is in the plane of the ring. The second component of the force drives the ring rotationally along the trajectory, perpendicular to the plane of the ring. The third component of the force lifts the ring against the upper flange of the raceway, especially the ring creates a high level of frictional drag between the ring and the raceway at the entry and exit points. let This frictional drag increases as the thread tension increases; As the spindle speed increases, it becomes larger, which ultimately limits the production rate. That will happen.

The object of the invention is to provide a traveler, a rotating ring supported on bearings and a Fiber debris and dust that normally accompany the raw material used in the spinning operation, without relying on the yarn guide. Operates unaffected by dust and other foreign substances and is free from wear during operation. The object of the present invention is to provide a method and device with low frictional force.

Other objects and advantages of the present invention are that storage packs mounted on the spindle during winding are A device for guiding the yarn into the cage, which consumes little energy and It has only a slight effect on the thread tension, making it easy to insert the thread, and the package Provides a means to automatically remove contaminants without interfering with the dotting operation. A method of guiding quantitative systems that provides what has been obtained, To reciprocate vertically parallel to the spindle to wind the storage package Providing made ring and track device, The ring device tracks the major part of the ring circumference. However, in the remaining part of the circumference (m1nor part), the orbit is Dimension the ring device relative to the track device to move away from the road; While the ring rotates on or in the orbit, the rings are spun and wound into packages. The spun yarn is made by running the taken yarn through the gap between the ring device and the track device. is wound into the package and the track is free from the accumulation of fiber debris and other contaminants. A method is provided, characterized in that the method automatically eliminates the

According to a second feature of the invention, a device for guiding the opening of the winding into the storage package. And, a ring dimensioned to rotate and reciprocate relative to the orbit; The trajectory is such that the ring circumference holds the main part or remains of the ring circumference while the ring is moving. The section is sized and oriented to hold the ring so that it is exposed and the spinning machine When used inside, the yarn to be spun and wound into a package is or the gap between the ring and the orbit is substantially obstructed while rotating on the orbit. Provided is a device characterized in that the device runs without any problems.

The track is designed to allow fiber debris and other contaminants to be free and free from interfering with the normal operation of the ring. It may have apertures through which such material may pass through, or it may have a structure without recesses in which such material may accumulate. It can also be made into a structure.

The raceway shall be circular in plan and formed by opposed radially extending flanges. Can be done. and releases fiber debris or other contaminants onto one or both flanges It is possible to provide an aperture for this purpose. Alternatively, the orbit can be formed as a simple ring. Can also be done. A ring is a simple cylinder configured to run in a limited orbit. It can also form as a body, or it can constrain itself to a circular orbit. It can also be formed with a U-shaped cross section. Both the ring and the orbit are shaped as segments of a sphere. It can also be formed as a section of a hollow sphere. The ring is The surface is rotated at an angle to the axis of the spindle and the surface is reciprocated within the surface. A hanging ring and a raceway that rotate by rolling on a raceway in a manner similar to that of the present invention Various configurations can be taken depending on the conditions.

The present invention will be described in detail below with reference to the accompanying drawings, in which FIG. 1 schematically shows, in cross-section, the basic elements of a type of ring spinning machine operating in the mode of operation;

One preferred design of the steering and trajectory is described.

Figure 3 shows the machine shown in Figures 1 and 2 installed on the ring rail of a ring spinning machine. The present invention for removing fiber debris and other contaminants is shown in Figure 1 as part of a The device according to the invention is shown in plan view.

FIG. 4 shows region A shown in FIG. 3 separated and spaced apart.

Figures 5.6, 7.8 and 9 show other alternative preferred designs of rings and tracks. vinegar.

Referring to FIG. 1, the sliver, roving or roving 1 is (not specified) and is drawn by the front drafting roller 3 as a strand 4. The strand 4 is pulled out using a pigtail guide 5, a finger or other balloon breaker. The storage package on the spindle 8 via the breaking device 20 and the ring guidance mechanism 6 This brings us to Ji7. The ring device is supported on the ring rail 9. is vertically reciprocating and gradually moves parallel to the spindle 8 to influence the formation of the package 7. do. The spindle 8 is driven against a pulley 11 forming a part of the spindle arm. The spindle pulley is driven through the spindle rail 13. It is mounted on a bearing 12 carried by the.

With reference to FIGS. 2 and 4, the yarn 4 of the strand goes to the yarn storage package 7. They are guided by a ring 14 that circulates along the way. The ring 14 is connected to the ring rail 9. It runs on a track 14 that is supported oppositely. Trajectory 15 is wall 16, against which The ring 14 is in contact with the flange 17. flange 17 limits the ring 14 to a fixed plane. The ring 14 is attached to the wall 16 of the track 15. The ring 1 has an outer diameter intermediate the distance between the diameter and the inside of the flange 17. 4 clears a small part around the flange 17 and then moves over most of the periphery. It is always confined between the flanges 17. Therefore, between the ring 14 and its orbit 15 A gap is created through which the thread 4 can be threaded without any hindrance. In action, thread The balloon formed at 4 rotates as the spindle 8 moves, but lags behind the movement of the spindle 8. , and slide around the periphery of ring 14. Upstream and below the point of contact with ring 14 The force on the ring 14 due to the tension in the section of the flow thread 4 and the force on the ring 14 The frictional tension of the thread causes the ring 14 to be displaced around the wall 16 in the track 15. Ru.

With reference to FIG. The surfaces are substantially parallel and inclined at an angle φ to the plane of the ring rail.

The angle φ ranges from 06 to 45°. Preferably, ring 14 and track 15 are spherical. , and thus the ring 14 moves around the raceway 15 together with the ball socket. It slides with a smooth motion similar to that of a universal joint or a spherical cross section. Turn around. The ring 14 then rolls in a complex movement within the track 15. that complicated luck The movement is restricted between the flanges 17 while shifting around the raceway wall 16 and the spindle. A plane parallel to the axis of spindle 8 with a plane at a rotation angle φ with respect to the axis of spindle 8. It includes reciprocating motion.

By configuring the ring 14 and the orbit 15 as segments of a sphere, the ring in the orbit can be The frictional tension of ring 1 due to thread tension is substantially reduced. 4 on the ring 14 at the point where it exits the track 15 during operation. This is because the direction is almost parallel to the direction of the moment of movement.

Due to the difference in diameter between the ring 14 and the raceway wall 16, the mass of the ring 14 is on the spindle 8. The speed of rotation of the ring 14 may be observed to rotate in the opposite direction to the direction of rotation. degree is a small fraction of the rotational speed of the spindle 8, while the center of mass of the ring 14 is rotating in the same direction as spindle 8 at the rotational speed of the balloon of thread 4. is observed. Therefore, the ring 14 has two components of rotational energy in motion. , and these energies are in opposite directions and of substantially equal magnitude, a ring The net energy consumption of 4 is thus the sliding friction of ring 4 between flanges 17. and the aerodynamic friction and the frictional tension of the thread 4 against the ring 14. Only the energy required for Therefore, phosphorus can be removed with only a small amount of energy consumption. The engine 14 can run at high speeds and there is almost no heating of the elements, because This is because the sliding speed between the ring 14 and its track 15 is low.

Although the sliding speed of the thread 4 on the ring 14 is high, local heating is ignored. because, This is because of the large contact wear surface of ring 14.

Referring to FIG. 3, the track 15 is in this example concentric with the axis of the spindle 8. It faces from the ring rail 9 which is in a plane perpendicular to . Between the ring 14 and the orbit 15 A slot 18 is cut through the track 15 in order to pass the thread 4 through the gap between the The rods are inclined relative to the plane of the ring 14. And the slot 18 allows the thread to be easily inserted. wide enough to pass through, but not significantly disturbing the smooth movement of ring 14. It's not that wide.

Near the slot 18 and also at other points around the track 15, the flange 17 are opened by recesses 19, which extend over a short arc of each flange 17. and extends to the depth of the wall 16 of the track. The purpose of this recess I9 is within the confines of track 15. The purpose is to provide a means for escaping the collection of fiber debris and other contaminants.

The shifting movement of the ring 14 within the track 15 is caused by the ring 14, the wall 16 and the flange of the track 15. The air pumping action is caused by the air being confined between the rings 17 and pushed in front of the ring 14. give rise to The air is then discharged in the recess 19 in the flange 17 of the raceway 15. The fibers and other contaminants that had entered the track 15 come out together with them. Filthy escape hand that the walls 16 of the track 15 may also be provided with openings for the purpose of providing stages; is obvious. However, this is undesirable, since against the track wall 16 The entire wall 16 may be held in place to ensure a smooth shifting movement of the ring 14. This is because it is preferable.

FIG. 5 shows an alternative preferred ring and track design in FIG. The cross-sectional shapes of the tracks 15 are interchanged. In this design, ring 14 is in orbit Run on 15. The track is within the ring and there is no possibility of dirt accumulation . This is because the fiber pieces that accumulate on the raceway 15 are used for the rolling and sliding motion of the ring 14. The ball is thrown more continuously to clear the working surface of the track 15. On the other hand, inside the ring 14 Fiber debris that accumulates in the slots is caused by centrifugation caused by the high velocity displacement of the ring 14. Continuously discharged by force.

FIG. 6 shows an alternative design of the ring and raceway. As shown in FIG. The inner diameter of the ring 14 is larger than the diameter of the wall 16 of the track 15. Hey. This gives the following advantages in operation: That is, around the wall 16 of the track. In order to roll the ring, the ring 14 is connected to the balloon made by the spindle 8 and the thread 4. rotating in the same direction and reducing the sliding speed of the thread 4 around the ring 14, thereby further to reduce frictional pull. Also in this design, the cross section of the ring 14 and the raceway 15 Figure 7 shows yet another design of the ring and track whose shapes can be interchanged. As shown in Figure 0, the orbit 15 keeps the ring 14 parallel to the axis of the spindle 8. It only serves to suppress it in the opposite direction. The ring 14 is connected to the yarn storage package 7 (A or the center of an empty package at the start of the spinning cycle). . The package has a yarn guide point 21 around the ring 14 that is located at the yarn storage package 8. allowed to remain at a constant distance from the surface, equal to the width of the ring 14, and then A guide point 2 created by a thread passing from a guide point 21 to the surface of the storage package 8 1 to the tangent to the ring 14 throughout the formed package. thus allowing the relationship between thread 4 and ring 14 to remain substantially constant. to maintain a substantially constant level of frictional pull throughout the spinning cycle between In this design, the cross-sectional shapes of the ring 14 and the raceway 15 can be replaced with each other. I want you to understand that it is possible.

Raceway 15 and associated ring 14 are made of stainless steel or other suitable material. It can be made of hard and strong materials. Raceway 15 and ring 14 are made of steel and plastic. They can also be made from different materials such as wood. This minimizes sliding friction force. and reduces the need for lubrication. Similarly, ring 14 is preferably highly polished. It is preferable that the thread 4 is properly connected to the thread 4, and that the thread 4 is suitably ringed to minimize the force of sliding friction between itself and the thread 4. be defined. The raceway 15 is provided with a lubrication system to lubricate the sliding movement between it and the ring 14. It is also possible to incorporate programs. Such lubrication is provided by the yarn 14 itself or by the current ring spinning. This is done by a wicking system similar to that commonly used on aircraft. .

FIG. 8 shows another preferred ring and track design in cross section. As shown in the figure, The cross section of the plug 14 is L-shaped. This ring is U-shaped with a flange 17. The flange 17, running in the track, restrains the ring in its plane of rotation. Rin The ring is formed on the surface 22 of the ring 14 running against one surface 23 of the flange 17. Drive on the road. This gives the following advantages: In other words, the ring operation on the orbit The moving surface is separate from the ring surface on which the thread slides. On the other hand, the thread 4 is the nose 2 of the ring 14. Touches only 5. With this design, the highly polished finish of the nose 25 is applied to the track wall 1. The possibility of injury due to friction against 6 is eliminated.

Figure 9 shows the design of the cylindrical ring and raceway in cross section. The resultant force of the forces exerted on the ring is within the bearing surfaces of ring 14 and raceway 15. It has limited dimensions. The ring 14 is attached to the bearing surface in the raceway against the bearing surface 24. It can be a plain cylinder running and supported. On the other hand, the flange 1 of the raceway The cylinder is restrained during 90. The length β° of the cylindrical ring 14 is due to the thread tension. The result of the force exerted on the ring °R' is the bearing surface 24 spaced apart. The direction is chosen to be restricted to a point in between. Thus, ring 14 above the track at the moment of exit from the track flange 17 and the moment of re-entry. Frictional tension between flange 17 and ring 14 is substantially reduced.

Thus, the present invention eliminates the problems associated with the accumulation of fiber debris and other dirt. A qualitatively free method and apparatus for guiding yarn during winding into storage packages is provided. Ru.

A particular sequence of the invention has been described. and without departing from the scope of the appended claims. Point out that corrections and changes may be made.
