Abstract
Description
Technical Field
[0001] This application relates to the field of spinning equipment technology, specifically to an automated device for single-spindle spandex 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 spandex core-spun yarn, with ring spinning being the most widely used. Spandex 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 spinning of spandex core-spun yarn is prone to core yarn breakage during production, resulting in hollow yarn, or core yarn breakage leading to core yarn wrapping around the rollers. This severely affects 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 ring spinning machines and lack linkage detection technology for single spindle positions of ring-spun spandex core-spun yarn, and cannot achieve digital control of the operating status of single spindle spandex filaments and rovings; they cannot link and complete a series of actions such as spandex filament breakage, roving breakage and alarm. Summary of the Invention

[0042] 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.
[0043] This application provides an automated device for single-spindle spandex core-spun yarn, which solves the technical problems of the ring spinning machine, such as the lack of linkage detection technology for single-spindle breakage and yarn breakage in ring-spun spandex core-spun yarn, and the inability to achieve digital control of the running status of single-spindle spandex filaments and rovings.
[0044] This application provides a single-spindle automated device for spandex core-spun yarn, which is installed on each spindle of a ring spinning machine 7 and is individually controlled by a central control center 13 installed on the ring spinning machine 7. It shares a speed encoder 1 that is communicatively connected to the central control center 13. The device includes a spandex filament feeding clutch 2 located below the roving 9, a functionalized guide wheel 3 located on the cradle of the ring spinning machine 7, a spandex filament breakage monitoring sensor 4, a yarn breakage monitoring sensor 5, and a roving braking device 6.
[0045] The ring spinning machine 7 includes a front roller 7-1, a rear roller 7-2, and a ring rail 7-3. The roving 9 is fed in sequentially through the roving brake device 6 and the rear roller 7-2. The spandex filament 10 enters the spandex filament breakage monitoring sensor 4 and the functionalized guide wheel 3 sequentially through the spandex filament feeding clutch 2, and is then fed into the front roller 7-1 and twisted into a fine yarn 11. The fine yarn 11 is twisted and wound after passing through the fine yarn breakage monitoring sensor 5 located on the ring rail 7-3.
[0046] Each spindle's speed encoder 1, spandex filament feeding clutch 2, functionalized guide wheel 3, spandex filament breakage monitoring sensor 4, yarn breakage monitoring sensor 5, and roving braking device 6 are all networked and digitally controlled by the central control center 13 of the ring spinning machine 7, located at the rear of the machine. The speed encoder 1 is communicatively connected to the front roller 7-1 of the ring spinning machine 7, monitoring its rotational speed in real time and transmitting the real-time speed data to the central control center 13. After the speed encoder 1 transmits the data to the central control center 13, the central control center 13 can adjust the rotational speed of the special-shaped drive wheel 2-1 of the spandex filament feeding clutch 2 based on the real-time rotational speed of the front roller 7-1, thereby controlling the feeding speed of the spandex filament 10.
[0047] The roving stop device 6 is located inside the ring spinning machine, close to the back roller 7-2. The roving 9 is fed into the back roller 7-2 through the roving stop device 6, where it is fused with the spandex filament 10 and the front roller 7-1. The spun spandex core-spun yarn is twisted and wound after passing through the yarn breakage monitoring sensor 5 located on the ring rail 7-3.
[0048] The spandex filament breakage monitoring sensor 4 includes one of the following types: capacitive, photoelectric, laser, and mechanical. The yarn breakage monitoring sensor 5 includes one of the following types: capacitive, photoelectric, laser, and mechanical.
[0049] An optional embodiment of the automated device for single-spindle spandex core-spun yarn further includes a yarn breakage alarm light 12, wherein the spandex filament yarn breakage monitoring sensor 4 and the yarn yarn breakage monitoring sensor 5 are both connected to the yarn breakage alarm light 12.
[0050] An optional embodiment of the automated device for single-spindle spandex core-spun yarn further includes a reset device 8, which is connected to the central control center 13 via a network communication.
[0051] The spandex filament feeding clutch 2 includes a shaped drive wheel 2-1, a shaped transmission wheel 2-2, a synchronous wheel 2-3, a front guide roller 2-4, a rear guide roller 2-5, a first belt 2-6, a second belt 2-7, a belt tensioning wheel 2-8, a compression spring 2-9, and a force application mechanism. The spandex filament breakage monitoring sensor 4 is located on the front of the spandex filament feeding clutch 2 housing.
[0052] It should be noted that Examples 1 to 4 are four different operating conditions for single-spindle spandex core-spun yarn automation devices. The difference lies in the spandex filament feeding clutch 2 in Examples 1 and 2, and in Examples 3 and 4, specifically in the different force application mechanisms.
[0053] Implementation 1
[0054] like Figure 1 , Figures 3-4 and Figure 8 As shown, the first embodiment is an automated device for single-spindle spandex core-spun yarn under normal spinning conditions. The force application mechanism in this embodiment includes a lifting shaft 2-10, a transverse electromagnetic rod 2-11, and a filament braking device 2-12.
[0055] Normal spinning process:
[0056] like Figure 1 , Figure 3 As shown, spandex filament 10 is placed on the front guide roller 2-4 and the rear guide roller 2-5. During spinning, the shaped drive wheel 2-1 engages with the shaped transmission wheel 2-2. The shaped drive wheel 2-1 drives the shaped transmission wheel 2-2 to rotate. The first belt 2-6 on the shaped transmission wheel 2-2 drives the synchronous wheel 2-3 to rotate. The second belt 2-7 on the synchronous wheel 2-3 drives the front guide roller 2-4 and the rear guide roller 2-5 to rotate. The belt tensioning wheel 2-8 is used to adjust the belt state. Under the drive of the front guide roller 2-4 and the rear guide roller 2-5, the spandex filament 10 actively unwinds and enters the spandex filament breakage monitoring sensor 4. After passing through the functionalized guide roller 3 and generating a sensing signal, it is fed into the front roller 7-1 of the ring spinning machine 7.
[0057] When the spandex filament 10 is in normal feeding state and no breakage occurs, the pressure spring 2-9 of the spandex filament feeding clutch 2 is working normally. Under the action of the pressure spring 2-9, the lifting shaft 2-10 of the force application mechanism is in the lower line position and is engaged and locked with the transverse electromagnetic rod 2-11.
[0058] In this embodiment, the spandex filament breakage monitoring sensor 4 is photoelectric type, and the spandex filament 10 is fed into the front roller 7-1 of the ring spinning machine 7 through the spandex filament breakage monitoring sensor 4.
[0059] Implementation 2
[0060] like Figure 1 , Figures 3-4 and Figure 8 As shown, Embodiment 2 is an automated device for single-spindle spandex core-spun yarn under the condition of spandex filament breakage. The force application mechanism in this embodiment includes a lifting shaft 2-10, a transverse electromagnetic rod 2-11, and a filament braking device 2-12.
[0061] The process in which the spandex filament 10 breaks but the yarn 11 does not break:
[0062] like Figure 1 , Figure 5 As shown, spandex filament 10 is placed on the front guide roller 2-4 and the rear guide roller 2-5. During spinning, the shaped drive wheel 2-1 engages with the shaped transmission wheel 2-2. The shaped drive wheel 2-1 drives the shaped transmission wheel 2-2 to rotate. The first belt 2-6 on the shaped transmission wheel 2-2 drives the synchronous wheel 2-3 to rotate. The second belt 2-7 on the synchronous wheel 2-3 drives the front guide roller 2-4 and the rear guide roller 2-5 to rotate. The belt tensioning wheel 2-8 is used to adjust the belt state. Under the drive of the front guide roller 2-4 and the rear guide roller 2-5, the spandex filament 10 actively unwinds and enters the spandex filament breakage monitoring sensor 4. After passing through the functionalized guide roller 3 and generating a sensing signal, it is fed into the front roller 7-1 of the ring spinning machine 7.
[0063] At this time, the spandex filament breakage monitoring sensor 4 detects the breakage information and immediately sends the filament breakage information to the central control center 13. The central control center 13 stores the information and controls the spandex filament feeding clutch 2 to stop moving, stopping the active feeding of spandex filament 10. At the same time, the roving braking device 6 starts moving, stopping the feeding of roving 9.
[0064] Upon receiving the control command from the central control center 13, a momentary current is applied to the transverse solenoid 2-11 of the spandex filament feeding clutch 2. Under the action of the current, the transverse solenoid 2-11 is momentarily magnetically applied, and is pulled by the magnetic force, releasing the locked state. At this time, the lifting shaft 2-10 is lifted upward by the pressure spring 2-9, changing from the lower wire position to the upper wire position, causing the shaped transmission wheel 2-2 to separate from the shaped drive wheel 2-1, and the spandex filament 10 stops feeding. The shaped transmission wheel 2-2 rises and engages with the filament braking device 2-12, ensuring that the spandex filament 10 no longer moves, preventing phenomena such as the spandex filament 10 getting tangled in the roller. The synchronous wheel 2-3, the front guide roller 2-4, and the rear guide roller 2-5 all stop rotating. The spandex filament 10 has no contact with the functional guide wheel 3, and the functional guide wheel 3 has no sensing, further confirming that the spandex filament 10 has stopped feeding.
[0065] After receiving the control command from the central control center 13, the roving brake device 6, which is linked to the spandex filament feeding clutch 2, starts to move. The roving brake device 6 breaks the roving 9 and stops feeding the roving.
[0066] At the same time, the central control center 13 controls the broken end alarm light 12 to light up and issue a warning, reminding the worker to handle the situation in time.
[0067] Implementation Three
[0068] like Figure 2 , Figure 6 and Figure 8 As shown, Embodiment 3 is an automated device for single-spindle spandex core-spun yarn under the condition of yarn breakage. The force application mechanism in this embodiment includes a filament braking device 2-12, an electromagnet plate 2-13, and a transmission wheel 2-14. At this time, the position of the roving braking device 6 is different from that of the roving braking device 6 in Embodiment 1. The roving braking device 6 is located on the cradle of the ring spinning machine 7 and is connected and close to the back roller 7-2.
[0069] The working process when the spandex filament 10 does not break but the yarn 11 does break:
[0070] like Figure 2 , Figure 6 The spandex filament 10 shown is placed on the front guide roller 2-4 and the rear guide roller 2-5. During spinning, the irregular drive wheel 2-1 engages and locks with the irregular transmission wheel 2-2. The irregular drive wheel 2-1 drives the irregular transmission wheel 2-2 to rotate. The first belt 2-6 on the irregular transmission wheel 2-2 drives the synchronous wheel 2-3 to rotate. The synchronous wheel 2-3 drives the transmission wheel 2-14 to rotate, thereby driving the front guide roller 2-4 and the rear guide roller 2-5 to rotate. At this time, the positive and negative poles of the electromagnet sheet 2-13 are in a non-magnetic state. Under the drive of the front guide roller 2-4 and the rear guide roller 2-5, the spandex filament 10 actively unwinds and enters the spandex filament breakage monitoring sensor 4. After passing through the functionalized guide roller 3 and generating a sensing signal, it is fed into the front roller 7-1 of the ring spinning machine 7.
[0071] At this time, the yarn breakage monitoring sensor 5 detects the yarn breakage information and immediately sends the yarn breakage information to the central control center 13. The central control center 13 stores the information and controls the spandex filament feeding clutch 2 to stop moving, stopping the active feeding of spandex filament 10; the roving braking device 6 starts moving, stopping the feeding of roving 9.
[0072] Upon receiving the control command from the central control center 13, the roving brake device 6 begins to move, breaking the roving 9 and stopping the feeding of roving. Simultaneously, the electromagnet 2-13 of the spandex filament feeding clutch 2, which is linked to the roving brake device 6, is energized with a momentary current. Under the action of the current, the electromagnet 2-13 is momentarily magnetized, and under the action of the magnetic force, the positive and negative poles of the electromagnet 2-13 attract each other, causing the shaped drive wheel 2-2 to separate from the shaped drive wheel 2-1, and the spandex filament 10 stops being fed. The shaped drive wheel 2-2 moves away from the shaped drive wheel 2-1 and engages with the filament brake device 2-12, ensuring that the spandex filament 10 no longer moves and preventing phenomena such as the spandex filament 10 getting tangled in the roller. Synchronous wheel 2-3, front guide roller 2-4, rear guide roller 2-5, and transmission wheel 2-14 all stop rotating. Although the spandex filament 10 is in contact with the functionalized guide roller 3, there is no continuous sensing signal between the spandex filament 10 and the functionalized guide roller 3 because the spandex filament 10 has stopped moving. This further confirms that the spandex filament 10 has stopped feeding.
[0073] At the same time, the central control center 13 controls the broken end alarm light 12 to light up and issue a warning, reminding the worker to handle the situation in time.
[0074] Implementation 4
[0075] like Figures 2 to 8 As shown, Embodiment 4 is an automated device for single-spindle spandex core-spun yarn under the condition of broken end resetting. The force application mechanism in this embodiment includes a transverse electromagnetic rod 2-11, a filament braking device 2-12, an electromagnet 2-15, an upper and lower electromagnetic rod 2-16, and an upper and lower limit device 2-17. In this embodiment, each spindle is equipped with a separate central control center 13.
[0076] When the operator receives the head break alarm, he presses the reset device 8 located on the cover of the spandex filament feeding clutch 2. The reset device 8 is connected to the central control center 13 of the spindle position. After receiving the reset information from the reset device 8, the central control center 13 of the spindle position controls the spandex filament feeding clutch 2 and the roving brake device 6 to reset.
[0077] After receiving the reset command from the central control center 13, the roving brake device 6 returns to its normal working state, and the roving conveyor is normal.
[0078] After receiving a reset command from the central control center 13, the spandex filament feeding clutch 2 is momentarily energized with a current through its transverse solenoid 2-11. Under the influence of this current, the transverse solenoid 2-11 is momentarily magnetically energized and pulled, releasing the lower limit lock. After a fixed interval, the upper and lower solenoids 2-16 are momentarily energized with a current. Under the influence of this current, the upper and lower solenoids 2-16 are momentarily magnetically energized and pulled downwards until the upper limit of the upper and lower limit devices 2-17 locks with the transverse solenoid 2-11. As the yarn changes from the lower to the upper position, the upper and lower electromagnetic rods 2-16 drive the irregularly shaped transmission wheel 2-2 to move downwards, separating from the filament braking device 2-12; it then engages with the irregularly shaped drive wheel 2-1 and is in the set position. The synchronous wheel 2-3, the front guide roller 2-4, and the rear guide roller 2-5 all begin to rotate, and the spandex filament 10 actively unwinds, enters the spandex filament breakage monitoring sensor 4, passes through the functionalized guide roller 3 and generates a sensing signal, and is then fed into the front roller 7-1 of the ring spinning machine 7 to achieve reset.
[0079] In summary, this application establishes an independent, networked detection and control device for each spindle on the ring spinning machine. This enables real-time, networked monitoring and digital control of the spandex filament and yarn status on a single spindle. By installing spandex filament breakage monitoring sensors and yarn breakage monitoring sensors, the device can monitor the breakage status of spandex filament and yarn in real time and collect and integrate breakage information. When a breakage occurs, the device can quickly stop the feeding of spandex filament and promptly break the roving, preventing problems such as entanglement with the roving and spandex filament caused by continued input, and reducing waste yarn generation. Each spindle on the ring spinning machine is equipped with a spandex filament feeding clutch to regulate the spandex filament feeding speed. This clutch, along with the spandex filament breakage monitoring sensors and yarn breakage monitoring sensors, monitors and controls the spandex core-spun yarn structure in real time, preventing defective spandex core-spun yarns such as missing or insufficient filaments, and ensuring the uniformity and consistency of the quality of ring-spun spandex core-spun yarn. By setting up warning lights for spandex filament and yarn breakage, the lights can be activated in a timely manner when spandex filament or yarn breaks, prompting the machine operator to handle the situation promptly, thereby improving worker efficiency and increasing production capacity.
[0080] The above are merely optional embodiments of this application and are not intended to limit this application. 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.
