Description

Technical Field

[0001] This application relates to the field of spinning equipment technology, specifically to an automated device for single-spindle filament core-spun yarn. Background Technology

[0002] With the improvement of living standards, people have put forward various requirements for textiles, such as personalization, diversification, and functionality, and have also placed higher demands on the diversity of yarn varieties. Currently, a large number of new textile raw materials are emerging, and various new textile technologies are constantly being developed. Multi-component composite yarns are one of the most promising new textile products. The emergence of composite spinning technology is not only conducive to improving spinning technology and equipment levels, but also provides new ways to change the structure, style, and quality of yarns and their fabrics.

[0003] There are many methods for producing filament core-spun yarn, with ring spinning being the most widely used. Core-spun yarn can be spun simply by installing a core-spun yarn device and tension control device on a ring spinning frame. However, ring-spun filament core-spun yarn is prone to core breakage during production, resulting in hollow yarn or yarn breakage, leading to core yarn wrapping around the rollers. This severely impacts production efficiency, reduces product quality, and wastes raw materials.

[0004] Currently, most spandex core-spun yarn breakage detection devices only have detection functions and no cutting functions, such as Chinese patent CN 2647879Y, Chinese patent CN206147899U, and Chinese patent CN205775033U.

[0005] Chinese patent CN205775033U discloses a composite yarn spinning device with a broken yarn detection function. When this device is working, the light emitted by the light source emitter is received by the light source receiver, the controller is in the open circuit state, and the alarm sounds. The filament or outer fiber is passed through a freely placed light-shielding tube in the broken yarn detector and then sequentially wound onto the guide wheel and roller. Adjusting the tension of the filament or outer fiber causes the light-shielding tube to move up and down, eventually bringing the center of the light-shielding tube to the same horizontal position as the light source emitter and maintaining stability. The light emitted by the light source emitter is blocked by the light-shielding tube, and the light source receiver cannot receive the light signal. At this time, the controller is in the open circuit state, and the alarm stops sounding. When the filament or outer fiber breaks or the tension is too low during operation, the light-shielding tube moves down along the outlet hole due to its own gravity. At this time, the light source receiver can receive the light emitted by the light source emitter, the controller is in the open circuit state, and the alarm sounds, alerting the operator. Ultimately, this achieves timely detection of broken filaments or outer fibers during operation.

[0006] Chinese patent CN210237893U discloses a roving braking device for a spinning frame. When a yarn breakage occurs in the spinning frame, an external single-spindle detection system detects the yarn breakage signal and sends a command to the roving braking device. The electromagnet inside the device is energized, forming a magnetic field and generating a suction force, which pulls down the iron plate that was originally raised. The iron plate releases the restriction on the pull rod, and the pull rod moves backward under the action of the spring. The pull rod pulls the roller retainer to swing forward, so that the roller retainer inserts into the gap between the rear roller and the driven roller. This prevents the rear roller from driving the driven roller to rotate, and the roving is stuck between the driven roller and the roller retainer and stops moving. The roving after passing through the roller continues to be conveyed outward due to the rotation of the middle roller, thus breaking the roving. It is also convenient to manually reset after stopping and can form a closed-loop automatic yarn conveying control with a yarn breakage detection device.

[0007] The aforementioned existing technologies mainly target the ring spinning machine as a whole, lacking linkage detection technology for single spindle positions of ring-spun filament core-spun yarn breakage and yarn breakage, and cannot achieve digital control of the running status of filament and roving; it cannot link a series of actions such as filament breakage, roving breakage and alarm to complete the process. Summary of the Invention

[0008] This application aims to address the technical deficiencies of the existing technology by providing a single-spindle automated device for filament core-spun yarn. This device enables real-time, networked monitoring and digital control of the status of each filament and yarn at each spindle position on a ring spinning machine. It effectively monitors filament and yarn breakage and collects and integrates breakage information, ensuring the uniformity and consistency of the quality of ring-spun filament core-spun yarn. The technical solution is as follows: An automated device for single-spindle filament core-spun yarn is installed at each spindle position of a ring spinning machine and is individually controlled by a central control center located on the ring spinning machine. It shares a speed encoder that is connected to the central control center. The device includes a filament yarn creel, a filament feeding clutch located below the roving, a functional guide wheel located on the cradle of the ring spinning machine, a filament breakage monitoring sensor, a yarn breakage monitoring sensor, and a roving braking device. The ring spinning machine includes a front roller, a rear roller, and a ring rail. The roving is fed in through the roving brake device and the rear roller. The filament is placed on the filament creel and fed in through the filament feeding clutch. After passing through the filament breakage monitoring sensor and the functionalized guide wheel, it is fed into the front roller and twisted into fine yarn. The fine yarn is twisted and wound after passing through the fine yarn breakage monitoring sensor on the ring rail. The filament feeding clutch, the functionalized guide wheel, the filament breakage monitoring sensor, the yarn breakage monitoring sensor, and the roving braking device are all connected to the central control center via network communication. The front roller is communicatively connected to the speed encoder, which transmits the real-time rotational speed of the front roller to the central control center. The central control center adjusts the filament feeding speed in real time based on the real-time rotational speed of the front roller. The functionalized guide wheel is located on the cradle of the ring spinning machine and has a sensing function. When the filament is continuously fed in, the filament contacts the functionalized guide wheel to generate a sensing signal. The functionalized guide wheel continues to rotate and generates a continuous sensing signal. The filament feeding clutch includes a shaped drive wheel, a shaped transmission wheel, a synchronous wheel, a front guide roller, a fixed roller, and a force application mechanism. The force application mechanism includes a first belt, a second belt, a first positioning hook, a second positioning hook, a leather roller, and scissors. During normal spinning, the shaped drive wheel of the filament feeding clutch engages and locks with the shaped transmission wheel. The shaped drive wheel drives the shaped transmission wheel to rotate, which in turn drives the front guide roller to rotate via the synchronous wheel, causing the filament to actively unwind and be fed in. When the filament breakage monitoring sensor or the yarn breakage monitoring sensor detects a breakage, the central control center controls the shaped transmission wheel of the filament feeding clutch to separate from the shaped drive wheel. The synchronous wheel and the front guide roller stop rotating, and the shears cut the filament located between the positioning hook and the rubber roller, stopping the filament feeding.

[0009] In a further technical solution, the roving braking device is located close to the rear roller, and the roving is fed into the rear roller through the roving braking device. The yarn breakage monitoring sensor is located on the ring rail.

[0010] Further technical solutions include filament breakage monitoring sensors that are one of capacitive, photoelectric, laser, or mechanical types, and yarn breakage monitoring sensors that are one of capacitive, photoelectric, laser, or mechanical types.

[0011] A further technical solution also includes a yarn breakage alarm light and a reset device. The filament breakage monitoring sensor and the yarn breakage monitoring sensor are both connected to the yarn breakage alarm light, and the reset device is connected to the central control center via a network communication connection.

[0012] Further technical solutions include an external filament yarn frame or an internal channel filament yarn frame.

[0013] A further technical solution for the filament feeding clutch also includes a pressure spring and a lifting shaft and electromagnetic rod for the force application mechanism.

[0014] Further technical solutions include an electromagnet plate and a transmission wheel as the force-applying mechanism.

[0015] The beneficial effects of the technical solution provided in this application include at least the following: (1) Each spindle of the ring spinning machine is equipped with an independent networked detection and control device to realize real-time networked monitoring and digital control of the status of filament and yarn on a single spindle.

[0016] (2) By setting up filament breakage monitoring sensors and yarn breakage monitoring sensors, the breakage of filament and yarn can be monitored in real time, and breakage information can be collected and integrated; ensuring the uniformity of the quality of ring-spun filament core-spun yarn; when a breakage occurs, the filament feeding clutch and the roving braking device operate in conjunction, which can quickly cut and stop the filament feeding and timely pull the roving, avoiding the occurrence of problems such as roving and filament continuing to be input, and reducing the generation of waste yarn.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] This application provides an automated single-spindle filament core-spun yarn device, which solves the technical problems in the prior art of being unable to achieve digital control of the running status of filaments and rovings, and being unable to link a series of actions such as filament breakage, roving breakage, and alarms. An independent networked detection and control device is set up at each spindle of the ring spinning machine to achieve real-time networked monitoring and digital control of the filament and yarn status. By setting up filament breakage monitoring sensors and yarn breakage monitoring sensors, the device can monitor the breakage status of filaments and yarns in real time and collect and integrate breakage information, ensuring the uniformity of the quality of ring-spun filament core-spun yarn.

[0021] The automated single-spindle filament core-spun yarn device is installed at each spindle position of the ring spinning machine 8 and is individually controlled by the central control center 14 located on the ring spinning machine 8. They share a speed encoder 1 that is communicatively connected to the central control center 14. Each single-spindle filament core-spun yarn automated device includes a filament yarn frame 2, a filament feeding clutch 4 located below the roving 10, a functional guide wheel 3 located on the cradle of the ring spinning machine 8, a filament breakage monitoring sensor 5, a yarn breakage monitoring sensor 6, and a roving braking device 7. The filament feeding clutch 2, the functional guide wheel 3, the speed encoder 1, the functional guide wheel 3, the filament feeding clutch 4, the filament breakage monitoring sensor 5, the yarn breakage monitoring sensor 6, and the roving braking device 7 are all networked and their movement is digitally controlled by the central control center 14 of the ring spinning machine.

[0022] The ring spinning machine 8 includes a front roller 8-1, a rear roller 8-2, and a ring rail 8-3. The functional guide roller 3 is located on the cradle of the ring spinning machine 8. The functional guide roller 3 has a sensing function. When the filament 11 comes into contact with the functional guide roller 3, a sensing signal is generated. When the filament 11 is continuously fed, the functional guide roller 3 rotates continuously, generating a continuous sensing signal.

[0023] Roving 10 is fed in via roving brake device 7 and rear roller 8-2. Filament 11 is placed on filament yarn holder 2, enters the roller 4-13 and scissors 4-14 via positioning hook 4-11 of filament feeding clutch 4, and then enters filament breakage monitoring sensor 5. After passing through functionalized guide roller 3, it is fed into front roller 8-1 of ring spinning machine 8 and twisted into yarn 12. Yarn 12 is then twisted and wound after passing through yarn breakage monitoring sensor 6 on ring rail 8-3. Speed ​​encoder 1 is connected to front roller 8-1 of ring spinning machine 8 to monitor the rotational speed of front roller 8-1 in real time and transmits the real-time speed to central control center 14. After the speed encoder 1 transmits the data to central control center 14, central control center 14 can adjust the rotational speed of the special-shaped drive wheel 4-1 of filament feeding clutch 4 in real time according to the real-time rotational speed of front roller 8-1, thereby controlling the feeding speed of filament 11.

[0024] The filament feeding clutch 4, the functionalized guide roller 3, the filament breakage monitoring sensor 5, the yarn breakage monitoring sensor 6, and the roving braking device 7 are all connected to the central control center 14 via network communication. The roving braking device 7 is located close to the rear roller 8-2, and the roving 10 is fed into the rear roller 8-2 through the roving braking device 7. The yarn breakage monitoring sensor 6 is located on the ring rail 8-3.

[0025] The filament breakage monitoring sensor 5 can be selected from one of the following types: capacitive, photoelectric, laser, or mechanical. The yarn breakage monitoring sensor 6 can be selected from one of the following types: capacitive, photoelectric, laser, or mechanical.

[0026] The single-spindle filament core-spun yarn automation device also includes a yarn breakage alarm light 13 and a reset device 9. The filament breakage monitoring sensor 5 and the yarn breakage monitoring sensor 6 are both connected to the yarn breakage alarm light 13, and the reset device 9 is connected to the central control center 14 via a network communication.

[0027] The filament yarn frame 2 can be selected as an external filament yarn frame or an internal channel filament yarn frame according to actual needs.

[0028] Implementation 1 and Implementation 2 employ an external filament yarn frame, which is a single-spindle filament core-spun yarn automation device for both normal spinning and filament breakage conditions.

[0029] Examples 3 and 4 employ an internal channel type filament yarn frame, which are automated single-spindle filament core-spun yarn devices for two working conditions: yarn breakage and breakage reset.

[0030] Implementation 1: Normal spinning conditions like Figure 1 , Figure 3 and Figure 5 , Figure 7 As shown, the automated single-spindle filament core-spun yarn device in this embodiment of the application adopts an external filament yarn frame. The external filament yarn frame includes a yarn frame body 2-1, a filament fixing device 2-2, a packaged filament 2-3, and a tension wheel 2-4.

[0031] The filament feeding clutch 4 is located below the roving 10. The filament feeding clutch 4 includes a special-shaped drive wheel 4-1, a special-shaped transmission wheel 4-2, a synchronous wheel 4-3, a front guide roller 4-4, a fixed roller 4-5, a compression spring 4-6, a lifting shaft of the force application mechanism 4-7, an electromagnetic rod 4-8, belts 4-9 and 4-10, positioning hooks 4-11 and 4-12, a leather roller 4-13, and a shear 4-14.

[0032] According to actual needs, the filament 11 is fixed on the fixing device 2-2 on the external filament yarn frame 2. The filament 11 is drawn out from the filament yarn frame 2, passes through the tension wheel 2-4, enters the positioning hook 4-11 of the filament feeding clutch, then enters the leather roller 4-13, and then enters the shear 4-14.

[0033] The specific working process under normal spinning conditions: During normal spinning, the spring 4-6 of the filament feeding clutch 4 works normally. Under the action of the spring 4-6, the lifting shaft 4-7 of the force application mechanism is in the lower position and is engaged and locked with the transverse electromagnetic rod 4-8. The irregular drive wheel 4-1 is engaged and locked with the irregular transmission wheel 4-2. The irregular drive wheel 4-1 drives the irregular transmission wheel 4-2 to rotate. The belt 4-9 on the irregular transmission wheel 4-2 drives the synchronous wheel 4-3 to rotate. The belt 4-10 on the synchronous wheel 4-3 drives the front guide roller 4-4 to rotate. Under the drive of the front guide roller 4-4, the filament 11 located between the rubber roller 4-13 and the front guide roller 4-4 is actively unwound. After passing through the scissors 4-14, it enters the filament breakage monitoring sensor 5. After passing through the functionalized guide roller 3 and generating a sensing signal, it is fed into the front roller 8-1 of the ring spinning machine 8.

[0034] At this time, the filament 11 is fed in normally without breaking. At this time, the pressure spring 4-6 of the filament feeding clutch 4 is working normally. Under the action of the pressure spring 4-6, the lifting shaft 4-7 of the force application mechanism is in the lower line position and is engaged and locked with the transverse electromagnetic rod 4-8.

[0035] The filament breakage monitoring sensor 5 is located on the cover of the filament feeding clutch 4. The filament breakage monitoring sensor 5 is photoelectric. The filament 11 is fed into the front roller 8-1 of the ring spinning machine 8 after passing through the filament breakage monitoring sensor 5.

[0036] The roving stop device 7 is located close to the rear roller 8-2 of the ring spinning machine 8. The roving 10 is fed into the rear roller 8-2 of the ring spinning machine 8 through the roving stop device 7, and condenses with the filament 11 and the front roller 8-1.

[0037] The spun filament core-spun yarn 12 is twisted and wound after passing through the yarn breakage monitoring sensor 6 located on the ring rail 8-3 of the ring spinning machine 8.

[0038] Implementation 2: Filament Breakage Case like Figure 1 , Figure 3 and Figure 5 , Figure 7 As shown, the automated single-spindle filament core-spun yarn device in this embodiment of the application adopts an external filament yarn frame. The external filament yarn frame includes a yarn frame body 2-1, a filament fixing device 2-2, a packaged filament 2-3, and a tension wheel 2-4.

[0039] The filament feeding clutch 4 is located below the roving 10; the filament feeding clutch 4 includes a special-shaped drive wheel 4-1, a special-shaped transmission wheel 4-2, a synchronous wheel 4-3, a front guide roller 4-4, a fixed roller 4-5, a compression spring 4-6, a lifting shaft of the force application mechanism 4-7, an electromagnetic rod 4-8, belts 4-9 and 4-10, positioning hooks 4-11 and 4-12, a leather roller 4-13, and a shear 4-14.

[0040] According to actual needs, the filament 11 is fixed on the fixing device 2-2 on the external filament yarn frame 2. The filament 11 is drawn out from the filament yarn frame 2, passes through the tension wheel 2-4, enters the positioning hook 4-11 of the filament feeding clutch, then enters the leather roller 4-13, and then enters the shear 4-14.

[0041] The filament breakage monitoring sensor 5 is located on the cover of the filament feeding clutch 4. The filament breakage monitoring sensor 5 is photoelectric. The filament 11 is fed into the front roller 8-1 of the ring spinning machine 8 through the filament breakage monitoring sensor 5 and the functionalized guide roller 3.

[0042] The roving stop device 7 is located close to the rear roller 8-2 of the ring spinning machine 8. The roving 10 is fed into the rear roller 8-2 of the ring spinning machine 8 through the roving stop device 7, and condenses with the filament 11 and the front roller 8-1.

[0043] The spun filament core-spun yarn is twisted and wound after passing through the yarn breakage monitoring sensor 6 located on the ring rail 8-3 of the ring spinning machine 8.

[0044] The specific working process under the condition of filament breakage: When a break occurs in the filament 11, the yarn 12 does not break. At this time, the filament breakage monitoring sensor 5 detects the breakage information and immediately sends the filament breakage information to the central control center 14. The central control center 14 stores the information and controls the filament feeding clutch 4 to stop moving and the roving braking device 7 to start moving.

[0045] Upon receiving the control command from the central control center 14, a momentary current is applied to the transverse solenoid 4-8 of the filament feeding clutch 4. Under the action of the current, the transverse solenoid 4-8 is momentarily magnetically applied, and the transverse solenoid 4-8 is pulled under the action of the magnetic force, releasing the locked state. At this time, the lifting shaft 4-7 of the force application mechanism is lifted upward under the action of the compression spring 4-6, changing from the lower wire position to the upper wire position, causing the irregular transmission wheel 4-2 to separate from the irregular drive wheel 4-1. The synchronous wheel 4-3 and the front guide roller 4-4 stop rotating, and the scissors 4-14 cut the filament located between the positioning hook 4-11 and the leather roller 4-13. The filament 11 stops feeding, and the filament 11 has no contact with the functional guide wheel 3. The functional guide wheel 3 has no sensing, further confirming that the filament 11 has stopped feeding.

[0046] After receiving the control command from the central control center 14, the roving brake device 7, which is linked to the filament feeding clutch 4, starts to move. The roving brake device 7 breaks the roving 10 and stops feeding the roving.

[0047] At the same time, the central control center 14 controls the broken end alarm light 13 to light up and issue a warning, reminding the worker to handle the situation in time.

[0048] Example 3: Yarn breakage case like Figure 2 , Figure 4 and Figures 6 to 7 As shown, the automated single-spindle filament core-spun yarn device in this embodiment of the application adopts an internal channel filament yarn frame. The internal channel filament yarn frame includes a yarn frame body 2-1, a filament fixing device 2-2, a packaged filament 2-3, and a transparent guide tube 2-5.

[0049] The filament feeding clutch 4 is located below the roving 10; the filament feeding clutch 4 includes a special-shaped drive wheel 4-1, a special-shaped transmission wheel 4-2, a synchronous wheel 4-3, a front guide roller 4-4, a fixed roller 4-5, belts 4-9 and 4-10, positioning hooks 4-11 and 4-12, a leather roller 4-13, a shear 4-14, an electromagnet plate 4-15, and a transmission wheel 4-16.

[0050] According to actual needs, the long filament 11 is fixed on the fixing device 2-2 on the inner channel type long filament yarn frame 2, and the long filament 11 is drawn out from the long filament yarn frame 2, fed into the transparent guide tube 2-5, enters the long filament feeding clutch 4 positioning hook 4-11, then enters the leather roller 4-13, and enters the shear 4-14.

[0051] The filament breakage monitoring sensor 5 is located on the cover of the filament feeding clutch 4. The filament breakage monitoring sensor 5 is photoelectric. The filament passes through the filament breakage monitoring sensor 5 and the functionalized guide wheel 3 in sequence before being fed into the front roller 8-1 of the ring spinning machine 8.

[0052] The roving stop device 7 is located close to the rear roller 8-2 of the ring spinning machine 8. The roving 10 is fed into the rear roller 8-2 of the ring spinning machine 8 through the roving stop device 7, and condenses with the filament 11 and the front roller 8-1.

[0053] The spun filament core-spun yarn is twisted and wound after passing through the yarn breakage monitoring sensor 6 located on the ring rail 8-3 of the ring spinning machine 8.

[0054] The specific working process under the condition of yarn breakage: When the filament 11 does not break but the yarn 12 does, the yarn breakage monitoring sensor 6 detects the yarn breakage information and immediately sends the information to the central control center 14. The central control center 14 stores the information and controls the filament feeding clutch 4 to stop moving and the roving braking device 7 to start moving.

[0055] Upon receiving the control command from the central control center 14, the roving brake device 7 begins to move, breaking the roving 10 and stopping the feeding of roving. Simultaneously, the electromagnet 4-15 of the filament feeding clutch 4, which is linked to the roving brake device 7, is energized with a momentary current. Under the action of the current, the electromagnet 4-15 is momentarily magnetized, and under the action of the magnetic force, the positive and negative poles of the electromagnet 4-15 attract each other, causing the shaped drive wheel 4-2 to separate from the shaped drive wheel 4-1. The synchronous wheel 4-3, the front guide roller 4-4, and the drive wheel 4-16 all stop rotating. However, under the action of the front roller 8-1 of the ring spinning machine 8, the filament 11 continues to be fed. At this time, the shears 4-14 cuts the filament, and the filament 11 has no contact with the functional guide wheel 3. The functional guide wheel 3 has no sensing, further confirming that the filament 11 has stopped being fed.

[0056] At the same time, the central control center 14 controls the broken end alarm light 13 to light up and issue a warning, reminding the worker to handle the situation in time.

[0057] Example 4: Severed head repositioning condition like Figure 2 , Figure 4 and Figures 6 to 7 As shown, the automated single-spindle filament core-spun yarn device in this embodiment of the application adopts an internal channel filament yarn frame. The internal channel filament yarn frame includes a yarn frame body 2-1, a filament fixing device 2-2, a packaged filament 2-3, and a transparent guide tube 2-5.

[0058] The filament feeding clutch 4 is located below the roving 10; the filament feeding clutch 4 includes a special-shaped drive wheel 4-1, a special-shaped transmission wheel 4-2, a synchronous wheel 4-3, a front guide roller 4-4, a fixed roller 4-5, belts 4-9 and 4-10, positioning hooks 4-11 and 4-12, a leather roller 4-13, a shear 4-14, an electromagnet plate 4-15, and a transmission wheel 4-16.

[0059] According to actual needs, the long filament 11 is fixed on the fixing device 2-2 on the inner channel type long filament yarn frame 2, and the long filament 11 is drawn out from the long filament yarn frame 2, fed into the transparent guide tube 2-5, enters the long filament feeding clutch 4 positioning hook 4-11, then enters the leather roller 4-13, and enters the shear 4-14.

[0060] The roving stop device 7 is located close to the rear roller 8-2 of the ring spinning machine 8. The roving 10 is fed into the rear roller 8-2 of the ring spinning machine 8 through the roving stop device 7, and condenses with the filament 11 and the front roller 8-1.

[0061] The spun filament core-spun yarn is twisted and wound after passing through the yarn breakage monitoring sensor 6 located on the ring rail 8-3 of the ring spinning machine 8.

[0062] The specific working process under the condition of resetting a severed head: When the filament 11 does not break but the yarn 12 does, the yarn breakage monitoring sensor 6 detects the yarn breakage information and immediately sends the information to the central control center 14. The central control center 14 stores the information and controls the filament feeding clutch 4 to stop moving and the roving braking device 7 to start moving.

[0063] Upon receiving the control command from the central control center 14, the roving brake device 7 begins to move, breaking the roving 10 and stopping the feeding of roving. Simultaneously, an instantaneous current is applied to the electromagnet 4-15 of the filament feeding clutch 4, which is linked to the roving brake device 7. Under the action of the current, the electromagnet 4-15 is momentarily magnetically charged. Under the action of the magnetic force, the positive and negative poles of the electromagnet 4-15 attract each other, causing the irregularly shaped transmission wheel 4-2 to separate from the irregularly shaped drive wheel 4-1. The synchronous wheel 4-3, the front guide roller 4-4, the rear guide roller 4-5, and the transmission wheel 4-15 all stop rotating. At this time, the scissors 4-14 cuts the filament. The filament 11 is not in contact with the functionalized guide wheel 3, and the functionalized guide wheel 3 has no sensing signal, further confirming that the filament 11 has stopped being fed.

[0064] At the same time, the central control center 14 controls the broken end alarm light 13 to light up and issue a warning, reminding the worker to handle the situation in time.

[0065] When the machine operator is in contact with the machine, press the reset device 9 located on the housing of the filament feeding clutch 4. The reset device 9 is connected to the central control center 14. After receiving the reset information from the reset device 9, the central control center 14 will control the filament feeding clutch 4 and the roving brake device 7 to reset.

[0066] After receiving the reset command from the central control center 14, the roving brake device 7 returns to its normal working state, and the roving conveyor is normal.

[0067] After receiving a reset command from the central control center 14, the filament feeding clutch 4 loses current, the electromagnet 4-15 loses magnetism, and the irregular drive wheel 4-1 engages and locks with the irregular transmission wheel 4-2. The irregular drive wheel 4-1 drives the irregular transmission wheel 4-2 to rotate, the belt 4-9 on the irregular transmission wheel 4-2 drives the synchronous wheel 4-3 to rotate, the synchronous wheel 4-3 drives the transmission wheel 4-16 to rotate, thereby driving the front guide roller 4-4 to rotate. Under the drive of the front guide roller 4-4, the filament 11 located between the rubber roller 4-13 and the front guide wheel 4-4 actively unwinds, passes through the scissors 4-14 and enters the filament breakage monitoring sensor 5. After passing through the functionalized guide wheel 3 and generating a sensing signal, the filament fed into the front roller 8-1 of the ring spinning machine 8 actively unwinds, passes through the front guide roller 4-4 and enters the filament breakage monitoring sensor 5, thus achieving a reset.

[0068] In summary, each spindle of the ring-spun filament core-spun yarn machine includes an independently networked detection and control device, enabling real-time monitoring and digital control of the filament and yarn status on a single spindle. By installing filament breakage monitoring sensors and yarn breakage monitoring sensors, the machine can monitor filament and yarn breakage in real time and collect and integrate breakage information, ensuring the uniformity of the quality of the ring-spun filament core-spun yarn. When a breakage occurs, the filament feeding clutch and roving braking device operate in tandem, quickly cutting and stopping the filament feeding and promptly breaking the roving. This prevents the roving and spandex filament from continuing to be fed in, avoiding problems such as entanglement with the rollers and reducing waste yarn generation. Each spindle on the ring spinning machine is equipped with a filament feeding clutch to regulate the filament feeding speed. This, combined with the filament and yarn breakage monitoring sensors, monitors and controls the filament core-spun yarn structure in real time, preventing defective filament core-spun yarn such as missing or insufficient filaments, thus ensuring the uniformity of the quality of the ring-spun filament core-spun yarn. By setting up warning lights for filament and yarn breakage, the lights can be activated in time to alert the machine operator when filament or yarn breaks, thus improving worker efficiency and increasing production capacity.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
