Description

Technical Field

[0001] This invention provides a dual-station winding and rewinding machine, belonging to the technical field of textile and yarn winding equipment. Background Technology

[0002] In the processing and production of silk threads, yarns, chemical fibers, and various flexible wires, winding machines are indispensable core supporting equipment. Their main function is to evenly and tightly wind the processed continuous wires onto a drum to form standardized spindles or spools, facilitating subsequent storage, transportation, dyeing, weaving, and other processes. As modern manufacturing moves towards automation, continuous operation, and high efficiency, the wire processing industry has placed increasingly higher demands on the winding efficiency, winding quality, ease of operation, and equipment stability of winding machines. Traditional winding equipment is gradually becoming unable to meet the actual needs of large-scale production, and its numerous shortcomings are becoming increasingly apparent.

[0003] Currently, the winding equipment widely used in the industry is mainly divided into two categories: single-station winding machines and simple multi-station winding machines. Among them, the single-station winding machine is the most basic winding equipment. It has a simple structure and low manufacturing cost, but its core drawback is that it cannot perform roll changing operations without stopping the machine. When a single roll is fully wound, the machine must be stopped to disassemble the full roll of yarn, replace the empty winding spool, and then restart the machine to resume winding. This method of stopping to change rolls not only causes production interruptions and significantly reduces production efficiency, but also, especially in high-speed wire processing scenarios, frequent shutdowns can lead to fluctuations in wire tension, which can easily cause problems such as wire breakage, loose winding, and uneven end faces, affecting product quality. At the same time, frequent manual disassembly and replacement of rolls is labor-intensive, inefficient, and prone to equipment failure or personnel safety hazards due to improper operation.

[0004] To address the shortcomings of single-station winding machines requiring downtime for rewinding, some manufacturers have introduced simplified multi-station winding machines. However, these machines still have many deficiencies and struggle to meet actual production needs. Firstly, simplified multi-station winding machines suffer from low rewinding positioning accuracy, mostly relying on manual or simple mechanical positioning methods. Significant deviations during rewinding can lead to yarn misalignment and winding deviation, affecting winding quality. Secondly, their tensioning and fixing mechanisms are poorly designed, often using bolts or single springs for tightening. This results in cumbersome drum loading and unloading, uneven tension, and potential drum loosening and slippage during winding, leading to loose yarn winding, chaotic yarn arrangement, and even unwinding. Furthermore, simplified multi-station winding machines lack effective anti-unwinding devices and tension stabilization mechanisms, resulting in significant yarn tension fluctuations during winding. When changing from a full roll, the yarn is prone to unwinding. Additionally, the power supply and signal transmission for rotating components often rely on direct wire connections, which can lead to wire wear and tangling over time, causing equipment malfunctions and impacting operational stability and lifespan.

[0005] Furthermore, the existing multi-station winding machines have relatively simple guide mechanisms, mostly using fixed guides or single-stroke guides, which cannot achieve precise guide switching during roll changes. This leads to thread jamming and breakage during roll changes, resulting in roll change failures. Simultaneously, their housing structure lacks effective locking and shock absorption mechanisms, resulting in significant housing vibration during operation. This not only affects winding accuracy but also accelerates wear on equipment components, shortening the equipment's lifespan. In addition, existing winding machines are not very user-friendly, mostly lacking integrated operation control components. Operations such as roll changes, start / stop, and parameter adjustments are cumbersome, hindering operational efficiency and making it difficult to adapt to the trend of large-scale, automated production.

[0006] In summary, current winding equipment on the market generally suffers from drawbacks such as low production efficiency, poor winding quality, inaccurate roll changing positioning, cumbersome operation, high labor intensity, and insufficient operational stability, failing to meet the wire processing industry's demands for continuous, efficient, and high-precision winding operations. Therefore, developing a dual-station roll changing and winding machine that can achieve automatic roll changing without stopping the machine, precise roll changing positioning, convenient roll loading and unloading, stable winding quality, simple operation, and reliable operation, thereby overcoming the shortcomings of existing technologies, has become an urgent technical problem to be solved in the current wire processing equipment field. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a dual-station rewinding machine that is compact in structure, highly efficient in rewinding, precise in positioning, easy to operate, stable in operation, and high in winding quality. This invention solves the technical defects of existing winding equipment, such as low efficiency in rewinding during downtime, inaccurate rewinding positioning, cumbersome loading and unloading of rolls, poor winding quality, and insufficient operational stability. It meets the needs of the wire processing industry for continuous, efficient, and high-precision winding operations.

[0008] To address the aforementioned problems, the present invention proposes the following technical solution: a dual-station roll-changing and winding machine, comprising a main body, on which are mounted an unloading handle, a tension flange, a turntable, an anti-scattering device, a winding drum, tension springs, grippers, guide plates, an outer casing, a casing locking mechanism, sensors, a roll-changing motor, induction plates, a synchronous belt, and conductive slip rings. A cam block is provided at the upper end of the unloading handle, and two tension springs are mounted on the winding shaft. A brush is installed at the bottom of the anti-scattering device; when the fully wound yarn spindle is switched to the unloading position, the brush of the anti-scattering device contacts the surface of the yarn spindle. The device uses a brush to contact the surface of the spindle to prevent the yarn from being thrown off the spindle, and at the same time assists the spindle in slowing down and stopping. The outer cover is a component of the housing assembly. The winding motor is connected to the turntable via a synchronous belt. The sensor cooperates with the sensing plate. The conductive slip ring is installed at the center of the turntable's rotation. The winding motor and its matching encoder are located on the turntable and rotate with it. The device also includes a tension bar, a fixed yarn guide roller, and an arc-shaped rod. After the yarn passes through the roller on the tension bar, the fixed yarn guide roller, and the arc-shaped rod in sequence, it enters the guide groove of the guide plate and reciprocates under the drive of the guide plate.

[0009] Furthermore, when the unloading handle is pulled up, the cam block at its upper end pushes the tension flange, causing the two tension springs on the winding shaft to loosen, thereby disassembling the winding spool; when the unloading handle is reset, the tension springs reset, thereby tightening and fixing the winding spool.

[0010] Furthermore, during the winding process, the winding drum rotates under the drive of the winding motor, and the yarn reciprocates under the drive of the guide plate, evenly distributing the yarn on the winding drum to complete the winding. After the winding station is fully wound, the unloading handle can be pulled to remove the wound spindle, and a new winding drum can be replaced.

[0011] Furthermore, the outer casing is equipped with four operation buttons: a green start button, a red stop button, a yellow casing assembly press-down button, and a blue manual roll change button.

[0012] Furthermore, the roll-changing trigger condition is pressing the blue manual roll-changing button, or the winding length reaches the system-set length. Meeting either condition initiates the roll-changing procedure. Once in the roll-changing procedure, the unwound station begins to rotate. The roll-changing motor drives the turntable to rotate via a synchronous belt, achieving position switching between the fully wound station and the unwound station. When the sensor detects the sensing plate, it determines that the turntable is in position, completing the position positioning for station switching. After the turntable is in position, the guide plate guides the yarn into the roll-changing stroke, bringing the yarn into the jaw position at the take-up shaft end. The normal take-up reciprocating stroke of the guide plate is indicated by the blue double-arrow area, and the roll-changing reciprocating stroke is indicated by the green double-arrow area.

[0013] Furthermore, after the chuck winds and fixes the wire, the guide plate drives the wire back to the blue double-arrow area for normal winding, and resumes reciprocating motion for normal winding; after the guide plate drives the wire back to the normal winding stroke, the wire is broken by the mutual pulling action of the two winding shafts, and the fully wound winding station slowly stops operating.

[0014] Furthermore, the housing locking mechanism is equipped with an electromagnet and a locking plate. Under normal conditions, the housing can only be raised and cannot be pressed down, reducing housing vibration and ensuring a flat winding surface. When the yellow housing assembly pressing button or the blue manual winding button is pressed, the electromagnet in the housing locking mechanism is energized and magnetized, attracting the locking plate and releasing the housing pressing restriction. The housing then automatically presses down under the action of gravity.

[0015] Furthermore, the encoders for the two take-up motors are installed on the rear side of the motors. The take-up motors and encoders rotate with the turntable, and the wires are led out to the outside of the take-up machine through the conductive slip ring at the center of rotation.

[0016] Furthermore, the winding operation steps are as follows: Step 1: Assemble the new take-up spool onto the take-up shaft, lower the unloading handle, and use the cam block to engage with the tensioning flange to reset the tensioning spring, thus completing the tensioning and fixing of the take-up spool. Step 2: The wire is wound around the roller on the tension bar, the wire-fixing roller, and the arc-shaped rod in sequence, and the end of the wire is introduced into the wire guide groove of the wire guide plate and fixed to the take-up drum. Step 3: Press the green start button on the outer casing. The winding motor starts and drives the winding drum to rotate. The guide plate drives the yarn to reciprocate. The yarn is evenly distributed on the winding drum to complete the winding operation.

[0017] Furthermore, the roll changing and unwinding procedures are as follows: Step 1: When the winding length reaches the system set length or the blue manual roll change button is pressed manually, the equipment triggers the roll change program. The unwound station starts to rotate, and the roll change motor drives the turntable to rotate through the synchronous belt, completing the position switch between the full roll station and the empty station, until the sensor detects the sensing sheet and the turntable is positioned in place. Step 2: The guide plate drives the wire into the changing stroke indicated by the green double arrow, and sends the wire to the chuck at the end of the new take-up shaft. After the chuck completes the winding of the wire, the guide plate drives the wire back to the normal take-up stroke indicated by the blue double arrow to resume winding. The wire is pulled and broken by the pull of the two take-up shafts, and the full-wound station slowly stops. Step 3: After the full roll station stops, manually pull the unloading handle. The cam block pushes the tension flange to release the tension spring. Remove the completed yarn spindle, assemble a new take-up spool, and lower the unloading handle to complete the tensioning. Wait for the next take-up or roll change instruction. Step four: During the process of switching the fully rolled spindle to the unloading station, the brush at the bottom of the anti-scattering device automatically contacts the surface of the spindle to prevent the yarn from being thrown out and to assist the spindle in slowing down and stopping.

[0018] Due to the adoption of the above technical solution, the beneficial effects of the dual-station rewinding and changing machine of the present invention are as follows: 1. The dual-station turntable structure, combined with automatic roll changing logic, enables non-stop station switching, completely solving the production interruption problem caused by the shutdown of traditional single-station winding machines for roll changing, significantly improving continuous production efficiency, and is especially suitable for high-speed wire processing scenarios, which can effectively reduce production time loss.

[0019] 2. The combination structure of unloading handle cam block + double tension spring is adopted to realize quick loading and unloading of winding drum. The operation is simple and labor-saving, and the tension is uniform and stable, which can effectively avoid the problem of drum loosening and slipping during winding and ensure winding quality.

[0020] 3. The precise cooperation between the sensor and the sensing plate enables accurate positioning during turntable roll changing with minimal positioning deviation. Combined with the partitioned reciprocating wire guide design of the guide plate, the roll changing process is smooth, effectively preventing wire misalignment, jamming, and breakage, ensuring uniform wire laying and a flat winding end.

[0021] 4. The housing locking mechanism can effectively reduce housing vibration during equipment operation, further improve winding accuracy and equipment operation stability, and extend equipment service life; the brush design of the anti-scattering device can not only prevent the yarn from scattering when changing full rolls of yarn, but also assist the yarn spindle to slow down and stop, improving operational safety.

[0022] 5. A conductive slip ring is installed at the center of the turntable rotation, which effectively solves the power supply and signal transmission problems of rotating components such as the winding motor and encoder. It avoids the wear and entanglement hazards caused by direct connection of traditional wires. The structure is compact and the operation is reliable, which further improves the service life and operational stability of the equipment.

[0023] 6. The outer casing integrates four clearly defined operation buttons, making it convenient to start / stop, change rolls, and adjust the casing, reducing the labor intensity of operators, improving operating efficiency, and adapting to the needs of large-scale and automated production.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The technical background of this application fully explains the problems of the prior art, and there are no overarching or general issues. The following description of the invention and specific embodiments will specifically describe the problems that this application needs to solve, clarify the technical problems that the technical solution needs to solve, and determine that the technical solution of this application has beneficial effects compared with the objective prior art.

[0030] Please see Figure 1-7As shown: This invention provides a dual-station rewinding and winding machine, comprising a main body 1, on which are provided an unloading handle 2, a tension flange 3, a turntable 4, an anti-scattering device 5, a winding drum 6, tension springs 7, claws 8, guide plates 9, an outer casing 10, a casing locking mechanism 11, a sensor 13, a rewinding motor 14, an induction plate 15, a synchronous belt 16, and a conductive slip ring 17. The unloading handle 2 has a cam block at its upper end, and two tension springs 7 are mounted on the winding shaft. A brush is installed at the bottom of the anti-scattering device 5; when the fully wound spindle is switched to the unloading position, the brush of the anti-scattering device 5 contacts the surface of the spindle. 5. A brush contacts the surface of the spindle to prevent the yarn from being thrown off the spindle, and at the same time assists the spindle to slow down and stop. The outer cover 10 is a component of the housing assembly. The winding motor 14 is connected to the turntable 4 through the synchronous belt 16. The sensor 13 cooperates with the sensing plate 15. The conductive slip ring 17 is installed at the rotation center of the turntable. The winding motor and the matching encoder are set on the turntable 4 and rotate with it. It also includes a tension bar, a fixed yarn guide roller, and an arc rod. After the yarn passes through the roller on the tension bar, the fixed yarn guide roller, and the arc rod in sequence, it enters the guide groove of the guide plate 9 and is reciprocated under the drive of the guide plate 9.

[0031] When the unloading handle 2 is pulled up, the cam block at its upper end pushes the tension flange 3, causing the two tension springs 7 on the winding shaft to loosen, thereby disassembling the winding tube 6; when the unloading handle 2 is reset, the tension springs 7 reset, thereby tightening and fixing the winding tube 6.

[0032] During the winding process, the winding drum 6 rotates under the drive of the winding motor, and the yarn reciprocates under the drive of the guide plate 9, so that the yarn is evenly distributed on the winding drum 6 to complete the winding. After the winding station is fully wound, the unloading handle 2 can be pulled to remove the wound yarn spindle, and a new winding drum 6 can be replaced.

[0033] The outer casing 10 is equipped with four operation buttons: a green start button, a red stop button, a yellow casing assembly press-down button, and a blue manual roll change button.

[0034] The roll change is triggered by pressing the blue manual roll change button or by the winding length reaching the system-set length. Meeting either condition initiates the roll change procedure. Once in the roll change procedure, the unwound station begins to rotate. The roll change motor 14 drives the turntable 4 to rotate via the synchronous belt 16, switching the position between the fully wound station and the unwound station. When the sensor 13 detects the sensing plate 15, it determines that the turntable 4 is in position, completing the position positioning for station switching. After the turntable 4 is in position, the guide plate 9 guides the yarn into the roll change stroke, bringing the yarn into the position of the jaw 8 at the end of the take-up shaft. The normal take-up reciprocating stroke of the guide plate 9 is represented by the blue double-arrow area, and the roll change reciprocating stroke is represented by the green double-arrow area.

[0035] After the clamp 8 winds and fixes the wire, the guide plate 9 drives the wire back to the blue double arrow area for normal winding, and resumes reciprocating motion for normal winding. After the guide plate 9 drives the wire back to the normal winding stroke, the wire is pulled apart by the mutual pulling action of the two winding shafts, and the fully wound winding station slowly stops operating.

[0036] The housing locking mechanism 11 is equipped with an electromagnet and a locking plate. Under normal conditions, the housing can only be raised and cannot be pressed down, reducing housing vibration and ensuring a flat winding surface. When the yellow housing assembly pressing button or the blue manual winding button is pressed, the electromagnet in the housing locking mechanism 11 is energized and magnetized, attracting the locking plate and releasing the housing pressing restriction. The housing then automatically presses down under the action of gravity.

[0037] The encoders for the two winding motors are installed on the rear side of the motors. The winding motors and encoders rotate with the turntable 4. The wires are led out to the outside of the winding machine through the conductive slip ring 17 at the center of rotation.

[0038] The winding operation steps are as follows: Step 1: Assemble the new take-up spool 6 onto the take-up shaft, lower the unloading handle 2, and use the cam block to engage with the tensioning flange 3 to reset the tensioning spring 7, thus completing the tensioning and fixing of the take-up spool 6. Step 2: The wire is wound around the roller on the tension bar, the wire-fixing roller, and the arc-shaped rod in sequence, and the end of the wire is introduced into the wire guide groove of the wire guide plate 9 and fixed to the take-up drum 6. Step 3: Press the green start button on the outer casing 10. The winding motor starts and drives the winding drum 6 to rotate. The guide plate 9 drives the yarn to reciprocate. The yarn is evenly distributed on the winding drum 6 to complete the winding operation.

[0039] The steps for changing and unloading rolls are as follows: Step 1: When the winding length reaches the system set length or the blue manual roll change button is pressed manually, the equipment triggers the roll change program. The unwound station starts to rotate, and the roll change motor 14 drives the turntable 4 to rotate through the synchronous belt 16 to complete the position switch between the full roll station and the empty station until the sensor 13 detects the sensing sheet 15 and the turntable 4 is positioned in place. Step 2: The guide plate 9 drives the wire into the changing stroke indicated by the green double arrow, and sends the wire to the chuck 8 at the end of the new take-up shaft. After the chuck 8 completes the winding of the wire, the guide plate 9 drives the wire back to the normal take-up stroke indicated by the blue double arrow to resume winding. The wire is pulled and broken by the pull of the two take-up shafts, and the full-winding station slowly stops. Step 3: After the full roll station stops, manually pull the unloading handle 2. The cam block pushes the tension flange 3 to release the tension spring 7. Remove the completed yarn spindle, assemble the new take-up tube 6, and lower the unloading handle 2 to complete the tensioning. Wait for the next take-up or roll change command. Step four: During the process of switching the fully rolled spindle to the unloading station, the brush at the bottom of the anti-scattering device 5 automatically contacts the surface of the spindle to prevent the yarn from being thrown out and to assist the spindle in slowing down and stopping.

[0040] A cam block is installed at the upper end of the unloading handle 1, and two tension springs 7 are mounted on the take-up shaft. The outer cover 10 is part of the housing assembly. The winding motor 14 is connected to the turntable 4 via a synchronous belt 16. The sensor 13 cooperates with the sensing plate 15. The conductive slip ring 17 is installed at the center of rotation of the turntable. The take-up motor and its matching encoder are located on the turntable 4 and rotate with it. It also includes a tension bar, a fixed wire guide roller, and an arc rod. The wire passes sequentially through the roller on the tension bar, the fixed wire guide roller, and the arc rod before entering the guide groove of the guide plate 9, where it reciprocates under the drive of the guide plate 9.

[0041] When the unloading handle 1 is pulled up, the upper end cam block pushes the tension flange 3, causing the two tension springs 7 on the winding shaft to loosen, thus disassembling the winding tube 6; when the unloading handle 1 is reset, the tension springs 7 reset, thus tightening and fixing the winding tube 6.

[0042] During the winding process, the winding drum 6 rotates under the drive of the winding motor, and the wire reciprocates under the drive of the guide plate 9, so that the wire is evenly distributed on the winding drum 6 to complete the winding.

[0043] The outer casing 10 has four operation buttons: a green start button, a red stop button, a yellow casing assembly press-down button, and a blue manual roll change button.

[0044] The roll change is triggered by pressing the blue manual roll change button or when the winding length reaches the system-set length; once either condition is met, the roll change procedure begins, and the unwound station starts rotating. The roll change motor 14 drives the turntable 4 to rotate via the synchronous belt 16, switching between the fully wound and unwound station positions. When the sensor 13 detects the sensing plate 15, it determines that the turntable 4 is in position, completing the station switching positioning. After the turntable 4 is in position, the guide plate 9 guides the yarn into the roll change stroke, bringing the yarn into the position of the take-up shaft end jaw 8. The normal winding reciprocating stroke of the guide plate 9 is indicated by the blue double arrow area, and the roll change reciprocating stroke is indicated by the green double arrow area.

[0045] After the chuck 8 secures the wire, the guide plate 9 guides the wire back to the blue double-arrow area for normal winding, resuming the reciprocating motion for normal winding. After the guide plate 9 guides the wire back to the normal winding stroke, the wire is broken by the mutual pulling action of the two winding shafts, and the wire slowly stops operating at the fully wound station.

[0046] After the winding has stopped at the station, pull the unloading handle 1 to remove the wound spindle and replace it with a new winding tube 6.

[0047] The housing locking mechanism 11 is equipped with an electromagnet and a locking plate. Under normal conditions, the housing can only be raised and cannot be pressed down, reducing housing vibration and ensuring a flat winding surface. When the yellow housing assembly pressing button or the blue manual winding button is pressed, the electromagnet is energized and magnetized, attracting the locking plate, releasing the housing pressing restriction, and the housing automatically presses down under gravity.

[0048] Two encoders are installed on the rear side of the two winding motors. The winding motors and encoders rotate with the turntable 4. The wires are led out to the outside of the winding machine through the conductive slip ring 17 at the center of rotation.

[0049] The bottom of the anti-scattering device 5 is equipped with a brush; when the fully rolled spindle is switched to the unloading position, the brush of the anti-scattering device 5 contacts the surface of the spindle to prevent the yarn from being thrown out of the spindle, and at the same time assists the spindle to slow down and stop rotating.

[0050] After the equipment starts, the yarn enters the guide plate 9 through the tension and guiding mechanism. The winding drum 6 rotates in conjunction with the reciprocating motion of the guide plate 9 to achieve uniform winding. When a full roll is reached or a manual roll change is triggered, the roll changer motor 14 drives the turntable 4 to rotate. The sensor 13 and the sensing plate 15 work together to achieve precise positioning. The guide plate 9 enters the roll change stroke, guiding the yarn to the clamp 8 for fixation. It then resets and breaks the yarn, completing the automatic roll change. After stopping at the full roll station, the unloading handle 1 quickly unloads the roll and replaces the empty tube, achieving continuous and efficient production.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.

The winding motors and encoders rotate with the turntable (4). The wires are led out to the outside of the winding machine through the conductive slip ring (17) at the center of rotation.

9. The dual-station rewinding machine according to claim 1, wherein the rewinding operation steps are as follows: Step 1: Assemble the new take-up spool (6) onto the take-up shaft, lower the unloading handle (2), and reset the tension spring (7) through the cam block and tension flange (3) to complete the tensioning and fixing of the take-up spool (6); Step 2: The wire is wound around the roller on the tension bar, the wire-fixing roller, and the arc-shaped rod in sequence, and the end of the wire is introduced into the wire guide groove of the wire guide plate (9) and fixed to the take-up drum (6). Step 3: Press the green start button on the outer casing (10). The winding motor starts and drives the winding drum (6) to rotate. The guide plate (9) drives the yarn to reciprocate. The yarn is evenly distributed on the winding drum (6) to complete the winding operation.

10. The method of using a dual-station rewinding and unwinding machine according to claim 1, wherein the rewinding and unwinding operation steps are as follows: Step 1: When the winding length reaches the system set length or the blue manual roll change button is pressed manually, the equipment triggers the roll change program. The unwound station starts to rotate, and the roll change motor (14) drives the turntable (4) to rotate through the synchronous belt (16) to complete the position switch between the full roll station and the empty station until the sensor (13) detects the sensing sheet (15) and the turntable (4) is positioned in place. Step 2: The guide plate (9) drives the wire into the green double arrow rewinding stroke and sends the wire to the chuck (8) at the end of the new take-up shaft. After the chuck (8) completes the wire winding, the guide plate (9) drives the wire back to the blue double arrow normal take-up stroke to resume take-up. The wire is pulled and broken by the pull of the two take-up shafts, and the full-wound station slowly stops. Step 3: After the full roll station stops, manually pull the unloading handle (2), the cam block pushes the tension flange (3) to release the tension spring (7), remove the completed yarn spindle, assemble the new take-up tube (6) and put down the unloading handle (2) to complete the tensioning, and wait for the next take-up or roll change command. Step 4: During the process of switching the fully rolled spindle to the unloading station, the brush at the bottom of the anti-scattering device (5) automatically contacts the surface of the spindle to prevent the yarn from being thrown out and to assist the spindle in slowing down and stopping.
