Description

Technical Field

[0001] This invention relates to the field of spinning, and particularly to a single-spindle detection system and method for spinning frames. Background Technology

[0002] In recent years, the traditional spinning industry has undergone profound changes, most notably in terms of significant progress in equipment automation, continuous operation, intelligence, high speed and efficiency, and low energy consumption, which has also promoted the shift towards higher quality and more diversified products. Automated spinning equipment is being widely used, and the pace of "machine replacing human labor" is accelerating. Adopting continuous spinning technology to shorten traditional spinning processes is also an important way to achieve "machine replacing human labor" and reduce labor costs. The adoption of intelligent technology is driving traditional spinning production towards online automatic monitoring. With the development of science and technology, especially the promotion and application of intelligent technology and the advancement of key spinning equipment manufacturing technology, favorable conditions have been created for high-speed operation of spinning equipment.

[0003] The spinning process is the final step in yarn production. It involves drafting and twisting the roving several times over to produce fine yarn with a specific count that meets relevant quality standards. The quality of the fine yarn ultimately determines the quality of the finished product. Simultaneously, the spinning process is one of the most crucial steps in a cotton textile mill. The size of a textile mill's production scale is expressed by the total number of spinning spindles. The output per spinning spindle reflects the production level of the textile enterprise. Indicators such as fine yarn quality, raw material and power consumption, and labor productivity reflect the technological and management level of the textile enterprise. The amount of energy consumed in the spinning process determines the cost of spinning, and the breakage rate per thousand spindles is a key performance indicator for enterprises.

[0004] In the spinning process, short-fiber rovings with a certain twist and strength are fed into the drafting system for drafting and thinning. The drafting system outputs short-fiber slivers of the required linear density. The short-fiber slivers are then twisted and wound onto the spinning tube according to certain forming requirements. During this process, the twisted yarn passes over the traveler straddling the ring and winds onto the spinning tube. The spindle rotates, which in turn drives the spinning tube embedded in the spindle to rotate synchronously. The rotation of the spinning tube then drives the traveler to rotate around the ring. Due to the weight of the traveler itself, the rotation speed of the traveler is less than that of the spinning tube. The difference in rotation speed between the two causes the yarn to continuously wind onto the spinning tube. During the winding process, the ring moves up and down along the height of the spinning tube, which in turn drives the traveler to move up and down accordingly. This achieves the control of the winding and forming of the yarn on the spinning tube. Therefore, the control of the ring plate's lifting and lowering directly achieves the control of the yarn forming. During the spinning process, the high-speed rotation of the traveler causes significant and fluctuating tension in the yarn during spinning, making it prone to breakage. Furthermore, the presence of the twisting triangle in ring spinning subjects the edge fibers within this triangle to greater tension, further contributing to breakage. Additionally, the twisting process from bottom to top is hindered, reducing the twist of the spinning section and creating weak-twist segments, ultimately leading to breakage. Therefore, reducing breakage and implementing online detection in ring spinning are currently hot research topics. A ring spinning breakage detection system can achieve online detection of yarn breakage at a specific spindle location. This data can be used for statistical analysis of production status and personnel management at that spindle location, expanding the system's functionality. However, existing detection systems typically use active light emission or magnetic field generation to detect the traveler's movement, making their reliability and stability susceptible to the complex environment of the spinning workshop.

[0020] Preferably, the embedding groove is provided with 3-5 sets of embedding rollers.

[0021] A method for detecting a single spindle of a spinning frame, using the aforementioned single spindle detection system, involves feeding the required short fiber roving into the drafting system during spinning. The short fiber roving is an aggregate with a certain twist, processed from the required short fibers. The fed short fiber roving passes sequentially through the drafting zone between the back drafting roller pair and the middle drafting roller pair, and the front drafting zone between the middle drafting roller pair and the front drafting roller pair within the drafting system to obtain the required short fiber sliver. The drafted short fiber sliver is continuously output after passing through the front nip between the front lower roller and the front upper rubber roller of the front drafting roller pair. The output short fiber sliver is then twisted by the twisting action transmitted from bottom to top to obtain short fiber yarn.

[0022] During the drafting process, the roller shaft of the front lower roller is driven to rotate by the drafting motor, which in turn drives the roller sleeve of the front lower roller to rotate synchronously, and then drives the roller sleeve of the front upper rubber roller, which is in close contact with it, to rotate. The roller shaft of the front lower roller drives the roller shaft of the rear lower roller to rotate through the overall drafting adjustment gear set, which in turn drives the roller sleeve of the rear lower roller to rotate synchronously, and then drives the roller sleeve of the rear upper rubber roller, which is in close contact with it, to rotate. The roller shaft of the rear lower roller drives the roller shaft of the middle lower roller to rotate through the rear drafting adjustment gear set, which in turn drives the roller sleeve of the middle lower roller to rotate synchronously, and then drives the roller sleeve of the middle upper rubber roller, which is in close contact with it, to rotate. Simultaneously, the main motor... The main drive shaft rotates, which in turn drives the spindles to rotate, which in turn drives the winding tube to rotate synchronously. The rotation of the winding tube then drives the staple yarn to rotate, which in turn drives the traveling wires around the track of the ring wires. Due to the weight of the traveling wires themselves, their rotational speed is less than that of the winding tube. This speed difference causes the resulting staple yarn to be continuously wound on the winding tube. The rotation of the traveling wires then drives the staple yarn to rotate synchronously, thus creating twist in the staple yarn. The resulting twist is transmitted from bottom to top along the length of the staple yarn. When it reaches the front nip, it causes the staple fiber sliver output from the drafting system to be twisted, forming the staple yarn.

[0023] Simultaneously, the forming drive motor drives the forming drive shaft to rotate counterclockwise, which in turn drives the forming drive gear to rotate synchronously. At this point, the driving teeth of the forming drive gear mesh with the driving teeth of the forming drive gear, thereby driving the forming drive shaft to rotate clockwise. This causes the suspension rope to continuously wind around the forming drive shaft, thus driving the ring plate to rise. This, in turn, drives the ring plate to rise synchronously, which in turn drives the wire traveler to rise synchronously. This, in turn, drives the short fiber yarn passing through the wire traveler to rise along the height direction of the winding tube, thus realizing the bottom-up winding of the short fiber yarn along the winding tube. As the ring plate rises... During the process, the front and rear insert rollers of the insert roller assembly on the sliding connecting rod rotate along the insert groove, thereby causing the sliding connecting rod to rise along the insert groove. Simultaneously, the lifting rod of the lifting connecting rod slides upward along the insert rod, resulting in a corresponding shortening of the lifting connecting rod. During this shortening process, the lifting spring changes from a stretched state to a naturally extended state and then to a compressed state. After the forming transmission gear has rotated half a circumference, the driving teeth of the forming transmission gear and the smooth part of the forming drive gear come into close contact, thus disconnecting the transmission connection between the forming drive motor and the forming drive shaft. Under the weight of the steel collar plate itself, the forming drive shaft then... The counter-clockwise rotation causes the suspension rope to unwind continuously from the forming shaft, resulting in a downward movement of the ring rail. This, in turn, causes the ring on the ring rail to descend synchronously, leading to a synchronous descent of the wire traveler. This, in turn, causes the short-fiber yarn passing through the wire traveler to descend along the height of the winding tube, thus achieving top-to-bottom winding of the short-fiber yarn along the winding tube. During the descent of the ring rail, the front and rear embedded rollers of the embedded roller assembly on the sliding connecting rod rotate along the embedded groove, thereby achieving a corresponding descent of the sliding connecting rod along the embedded groove. Simultaneously, the lifting rod of the lifting connecting rod slides downward along the embedded rod, thus achieving the lifting connection... The corresponding extension of the connecting rod, and during the extension process, the lifting spring changes from a compressed state to a naturally extended state and then to a stretched state, so that the descent speed of the steel ring plate gradually increases and then gradually decreases, thereby achieving adaptive tube bottom forming control. After the forming transmission gear rotates half a circle, the driving teeth of the forming transmission gear and the driving teeth of the forming drive gear engage with each other. At this time, under the stretching action of the lifting spring in the stretched state, the steel ring plate generates an upward movement tendency, so that the driving teeth of the forming transmission gear and the driving teeth of the forming drive gear engage naturally without rigid collision, thereby effectively reducing damage to the forming transmission gear and the forming drive gear.

[0024] During the spinning process, yarn breakage on a single spindle is monitored in real time. In normal spinning, the traveler rotates around the ring's traveler track, generating friction. This friction causes the triboluminescent coating on the traveler track to emit light, which is received by a light receiver surrounding the ring. The received light signal is amplified, and the amplified signal breaks the circuit of the yarn breakage indicator light, keeping it in a non-alarm state. When a yarn breakage occurs, the traveler stops rotating, eliminating the friction on the triboluminescent coating and causing the corresponding light to disappear. This prevents the light receiver from receiving the light signal, thus breaking the circuit of the yarn breakage indicator light and putting it in an alarm state. This allows the indicator light to display the yarn breakage during spinning.

[0025] Compared with the prior art, the beneficial effects of the technical solution of the present invention are as follows: The present invention sets a coating of triboluminescent material on the track of the ring and sets a light receiving device around the ring on the ring plate, thereby realizing real-time monitoring of the movement state of the wire loop by whether the light receiving device receives a light signal, and then realizing real-time monitoring of yarn breakage, thereby changing the traditional monitoring method that relies on an external active light-emitting device to generate a light source, and effectively improving the durability and reliability of the device.

[0041] refer to Figure 1-2 This invention relates to a single-spindle testing method for a spinning frame. During spinning, the required short fiber roving is fed into the drafting system. The short fiber roving is an aggregate with a certain twist, processed from the required short fibers. The fed short fiber roving passes sequentially through the drafting zone between the rear drafting roller pair 1 and the middle drafting roller pair 2, and the front drafting zone between the middle drafting roller pair 2 and the front drafting roller pair 3 to obtain the required short fiber sliver. The drafted short fiber sliver is continuously output after passing through the front nip between the front lower roller and the front upper rubber roller of the front drafting roller pair 3. The output short fiber sliver is twisted by the twisting action transmitted from bottom to top to obtain short fiber yarn.

[0042] During the drafting process, the roller shaft of the front lower roller is driven to rotate by the drafting motor 4, which in turn drives the roller sleeve of the front lower roller to rotate synchronously, and then drives the roller sleeve of the front upper rubber roller, which is in close contact with it, to rotate. The roller shaft of the front lower roller drives the roller shaft of the rear lower roller to rotate through the overall drafting adjustment gear set 5, which in turn drives the roller sleeve of the rear lower roller to rotate synchronously, and then drives the roller sleeve of the rear upper rubber roller, which is in close contact with it, to rotate. The roller shaft of the rear lower roller drives the roller shaft of the middle lower roller to rotate through the rear drafting adjustment gear set 6, which in turn drives the roller sleeve of the middle lower roller to rotate synchronously, and then drives the roller sleeve of the middle upper rubber roller, which is in close contact with it, to rotate. At the same time, the main motor 15 drives the transmission main shaft 1. The rotation of spindle 6 causes each spindle 14 to rotate, which in turn causes the winding tube 9 to rotate synchronously. The rotation of the winding tube 9 then causes the staple yarn to rotate, which in turn causes the traveling wire 12 to rotate around the traveling wire track of the ring 11. Due to the weight of the traveling wire 12 itself, its rotational speed is less than that of the winding tube 9. This speed difference causes the resulting staple yarn to be continuously wound on the winding tube 9. The rotation of the traveling wire 12 then causes the staple yarn to rotate synchronously, thereby generating twist in the staple yarn. The generated twist is transmitted from bottom to top along the length of the staple yarn. When it reaches the front nip, the staple sliver output by the drafting system is twisted to form staple yarn.

[0043] Simultaneously, the forming drive motor 7 drives the forming drive shaft 19 to rotate counterclockwise, which in turn drives the forming drive gear 20 to rotate synchronously. At this time, the driving teeth of the forming drive gear 20 first engage with the driving teeth of the forming drive gear 22, thereby driving the forming drive shaft 21 to rotate clockwise through the forming drive gear 22. This causes the suspension rope 8 to continuously wind around the forming drive shaft 21, thereby driving the ring plate 10 to move upward, which in turn drives the ring 11 on the ring plate 10 to move upward synchronously, which in turn drives the wire loop 12 to move upward synchronously. This causes the short fiber yarn passing through the wire loop 12 to move upward along the height direction of the winding tube 9, thereby realizing the upward winding of the short fiber yarn along the winding tube 9 from bottom to top. During the upward movement of the steel collar plate 10, the front and rear embedded rollers of the embedded roller assembly 25 on the sliding connecting rod 24 rotate along the embedded groove, thereby achieving the corresponding upward movement of the sliding connecting rod 24 along the embedded groove. Simultaneously, the lifting rod of the lifting connecting rod 26 slides upward along the embedded rod, resulting in the corresponding shortening of the lifting connecting rod 26. During this shortening process, the lifting spring 27 changes from a stretched state to a naturally extended state and then to a compressed state. After the forming transmission gear 20 has rotated half a circumference, the driving teeth of the forming transmission gear 20 and the smooth part of the forming drive gear 22 come into close contact, thereby disconnecting the transmission connection between the forming drive motor 7 and the forming drive shaft 21. This allows the steel collar plate 10 itself to... Under the influence of gravity, the forming drive shaft 21 rotates counterclockwise, causing the suspension rope 8 to continuously unwind from the forming drive shaft 21. This causes the ring plate 10 to descend, which in turn causes the ring 11 on the ring plate 10 to descend synchronously, and the wire loop 12 to descend synchronously. This causes the short fiber yarn passing through the wire loop 12 to descend along the height direction of the winding tube 9, thus achieving the top-to-bottom winding of the short fiber yarn along the winding tube 9. During the descent of the ring plate 10, the front and rear embedded rollers of the embedded roller assembly 25 on the sliding connecting rod 24 rotate along the embedded groove, thereby achieving the corresponding descent of the sliding connecting rod 24 along the embedded groove. At the same time, the lifting connecting rod 26... The lifting rod slides downwards along the embedded rod, thereby extending the lifting connecting rod 26 accordingly. During this extension, the lifting spring 27 changes from a compressed state to a naturally extended state and then to a stretched state. This causes the descending speed of the steel collar plate 10 to gradually increase and then gradually decrease, achieving adaptive tube bottom forming control. After the forming transmission gear 20 has rotated half a circumference, the driving teeth of the forming transmission gear 20 and the driving teeth of the forming transmission gear 22 engage with each other. At this time, under the stretching action of the lifting spring 27, the steel collar plate 10 tends to move upwards, allowing the driving teeth of the forming transmission gear 20 and the driving teeth of the forming transmission gear 22 to engage naturally without rigid collision.This effectively reduces damage to the forming transmission gear 20 and the forming drive gear 22;

[0044] During the spinning process, yarn breakage of a single spindle is monitored in real time. During normal spinning, the traveler 12 rotates around the traveler track of the ring 11, generating friction on the traveler track. This friction causes the triboluminescent coating on the traveler track to emit light, which is received by a light receiver 13 surrounding the ring 11. The light signal received by the light receiver 13 is amplified, and the amplified signal breaks the circuit of the yarn breakage indicator light, thus keeping the indicator light in a non-alarm state. When a yarn breakage occurs, the traveler 12 stops rotating, causing the friction on the triboluminescent coating on the traveler track to disappear, resulting in the disappearance of the corresponding light. Consequently, the light receiver 13 cannot receive the light signal, and the circuit breaking effect on the yarn breakage indicator light disappears, putting the indicator light in an alarm state. This enables the indicator light to display the yarn breakage during spinning.

[0045] In the aforementioned process, the contact surfaces of the steel traveler 12 and the steel ring 11, and the contact surfaces of the steel traveler 12 and the yarn are different. Therefore, it takes a certain amount of time for the heat generated by friction during the high-speed rotation of the steel traveler 12 to be transferred to the yarn. The heat generated by friction will also be dissipated as the steel traveler rotates at high speed. In other words, the heat generated is dissipated into the air before it is transferred to the yarn, so it will not affect the yarn.

[0046] Example 3:

[0047] Based on the aforementioned embodiments, the triboluminescent coating uses Sr2P2O7:Eu,Y, a triboluminescent material with dual luminescent centers developed by the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences. When this material is composited onto a polydimethylsiloxane (PDMS) matrix, it exhibits bright, continuous, and color-tunable triboluminescence under mechanical action. Wear and tear during the service life of the steel collar 11 will not affect the luminescence effect. The steel collar 11 needs to be replaced after a certain period of use, and the coating will be replaced accordingly upon replacement.
