Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to an automatic doffing device for a texturing machine. Background Technology

[0002] In the continuous development of textile technology, texturing machines have become indispensable key equipment on textile production lines, thanks to their ability to transform untwisted yarns such as nylon, polyester (POY), and polypropylene into elastic yarns with medium to low elasticity through false twisting. With the increasing trend towards large-scale and automated production in the textile industry, the production efficiency and automation level of texturing machines have become important factors restricting enterprise development, and the yarn winding process, in particular, has a direct impact on overall production efficiency.

[0003] Currently, most traditional texturing machines on the market still widely rely on manual operation for yarn bobbin winding. Operators must manually and precisely place empty yarn bobbins onto the winding device before starting the machine. Once the set winding amount is reached, the full bobbin must be manually removed from the winding device before a new empty bobbin is placed to continue production. This traditional manual operation method has multiple drawbacks. From an operational perspective, manually loading and unloading yarn bobbins is cumbersome and requires operators to maintain high concentration and precise technique for extended periods. Repetitive mechanical movements easily lead to operator fatigue, significantly increasing labor intensity. In terms of production efficiency, manual operation is much slower than automated equipment. Frequent manual intervention compresses the effective working time of the texturing machine, significantly extending the production cycle and making it difficult to meet the large-scale, continuous production needs of modern textile enterprises. From a safety perspective, manual operation poses significant safety hazards. Under prolonged high-intensity operation, operator errors can not only damage equipment but also threaten personal safety. Furthermore, the manual operation mode has led to high labor costs, which, with labor costs rising year by year, further squeezes the profit margins of enterprises. Therefore, developing an automatic bobbin unloading device suitable for texturing machines to automate the loading and unloading of yarn bobbins is of great practical significance for improving the production efficiency of texturing machines, reducing labor intensity, ensuring production safety, and saving production costs for enterprises. Utility Model Content

[0004] In view of this, this utility model proposes an automatic bobbin dropping device for a texturing machine. This device is equipped with a bobbin storage mechanism that can simultaneously hold two empty bobbins, each undertaking a different task. One empty bobbin is in standby mode as a backup; the other empty bobbin is ready to be fed into the winding device for winding operations. When the texturing machine completes a winding cycle and the worker removes the fully wound bobbin, the automatic bobbin dropping device responds quickly, automatically and precisely delivering the prepared empty bobbin to the winding position without manual intervention, immediately initiating a new round of winding. This design significantly reduces manual operation, substantially improves the working efficiency of the texturing machine, and optimizes the entire production process.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An automatic bobbin dropping device for a texturing machine includes a bobbin storage mechanism, a guide rail, a swing arm, a rotating shaft, a cylinder, and a wall plate. The guide rail is fixed to the wall plate, and the bobbin storage mechanism is slidably mounted on the guide rail, allowing it to move freely on the guide rail. The swing arm is rotatably fixed to the wall plate via the rotating shaft, and its end is movably connected to the bobbin storage mechanism. The cylinder is fixed to the wall plate, and its actuating end is connected to the swing arm. By pushing and retracting the cylinder, the bobbin storage mechanism is pushed out or reset. Specifically, when bobbin dropping is required, the cylinder on the automatic bobbin dropping device actuates, thereby driving the swing arm to rotate around the fixed rotating shaft, causing the bobbin storage mechanism to move towards the bobbin holder. After the movement is complete and the bobbin is removed, the cylinder actuates again, driving the swing arm to reset it.

[0007] In a structure that optimizes the aforementioned solution, a return spring is also included. One end of the return spring is fixed to the wall panel, and the other end is connected to the swing arm. During the operation of the automatic drum lowering device, after the cylinder drives the swing arm to complete the drum lowering action, it needs to reset in order to perform the next operation. The return spring can provide an elastic force to assist the swing arm in resetting, which on the one hand accelerates the resetting speed of the swing arm, reduces waiting time, and improves the working efficiency of the device; on the other hand, it shares part of the load of the cylinder, reduces the pressure on the cylinder due to frequent extension and retraction, extends the service life of the cylinder, and enhances the stability of the swing arm resetting process, ensuring that each resetting is accurate and ensuring the continuity of the automatic drum lowering device operation.

[0008] In a structure that optimizes the aforementioned solution, a stop rod is also included. This stop rod is fixed to the wall panel and engages with the yarn bobbin storage mechanism. When the yarn bobbin storage mechanism moves on the guide rail, it needs to accurately stop at the position where it connects with the bobbin holder to ensure that the yarn bobbins can be smoothly grasped and placed. The stop rod, acting as a limiting component, interacts with the yarn bobbin storage mechanism when it moves to the predetermined position, preventing further movement and achieving precise positioning. This avoids the problem of inaccurate yarn bobbin handover due to excessive or insufficient movement of the yarn bobbin storage mechanism, improving the accuracy and reliability of the bobbin dropping operation and ensuring the smooth operation of the texturing machine's winding process.

[0009] In a structure that optimizes the aforementioned solution, the connection point between the cylinder's actuating end and the swing arm is located below the rotating shaft. Specifically, when the yarn bobbin needs to be lowered, the cylinder retracts, driving the yarn bobbin storage mechanism towards the bobbin holder; once the movement is complete and the yarn bobbin is removed, the cylinder extends, driving the swing arm to reset. By placing the connection point between the cylinder and the swing arm below the rotating shaft, a highly efficient mechanical transmission structure is constructed using the lever principle. When the cylinder retracts or extends, a relatively small driving force can be used to achieve a large-scale movement of the yarn bobbin storage mechanism through the rotation of the swing arm around the rotating shaft. This design not only improves power transmission efficiency and reduces energy consumption, but also allows for more precise control of the movement distance and speed of the yarn bobbin storage mechanism, ensuring a smooth and accurate lowering process, while also enabling the reset action to be completed quickly and stably, guaranteeing the high efficiency and stability of the automatic lowering device.

[0010] In a structure that optimizes the aforementioned solution, the yarn bobbin storage mechanism includes a housing, rollers, and a gripping unit. The housing can simultaneously hold at least two empty yarn bobbins. Two sets of rollers are respectively arranged on both sides of the housing. The first set of rollers is slidably connected to a guide rail, and the second set of rollers is slidably embedded in a long groove at the end of a swing arm. The gripping unit is located at the front of the housing. The yarn bobbin storage mechanism is the core component of the automatic bobbin dropping device for storing and conveying yarn bobbins. The housing accommodates at least two empty yarn bobbins, meeting the storage needs of spare and unwound yarn bobbins, ensuring continuous production of the texturing machine. The design of the two sets of rollers allows the yarn bobbin storage mechanism to slide smoothly on the guide rail, achieving docking with the bobbin holder, and also allows for linkage when the swing arm is driven by a cylinder through the cooperation of the second set of rollers with the long groove at the end of the swing arm, ensuring the accuracy and stability of movement. The gripping unit at the front is responsible for firmly clamping the yarn bobbin to be retrieved, preventing the yarn bobbin from falling or shifting during movement, ensuring the safety and reliability of the yarn bobbin during the handover process.

[0011] In a structure that optimizes the aforementioned solution, the housing includes an upper housing and a lower housing, which are connected by a connecting piece. Two sets of rollers are mounted on the lower housing. Spare yarn bobbins are stored within the housing space formed by the lower and upper housings. This structure provides a stable and enclosed storage space for the yarn bobbins, protecting them from external factors. After a yarn bobbin to be retrieved is taken, a worker needs to place a spare yarn bobbin. At this time, the spare yarn bobbin is pushed forward to become the new yarn bobbin to be retrieved.

[0012] In a structure that optimizes the aforementioned solution, the gripping unit includes grippers and clamping plates. Two clamping plates are installed at the front end of the upper housing, and two grippers are installed at the front end of the lower housing. The grippers are fixed to the lower housing via a base. The yarn bobbin to be retrieved at the front end is clamped by the grippers and clamping plates from both the top and bottom. The gripping unit uses a gripping method where the grippers and clamping plates work together vertically, which can apply a stable clamping force to the yarn bobbin from both vertical directions, ensuring that the yarn bobbin to be retrieved will not loosen, fall, or shift position during the movement of the yarn bobbin storage mechanism. This symmetrical clamping design provides a uniform and reliable clamping effect, enabling the yarn bobbin to maintain an accurate position when it intersects with the bobbin holder, avoiding winding errors caused by yarn bobbin shaking or shifting, thereby improving the reliability and stability of the texturing machine's bobbin dropping operation and ensuring the product quality produced by the texturing machine.

[0013] In a structure that optimizes the aforementioned solution, the gripper can rotate around its base, on which a torsion spring is mounted. Since yarn bobbins of different specifications may differ in shape and size, the gripper's rotation around the base, combined with the torsion spring design, allows for adaptive adjustment based on the actual condition of the yarn bobbin. When gripping a yarn bobbin, the gripper can flexibly conform to the bobbin surface, ensuring stable gripping of yarn bobbins of different specifications. After the yarn bobbin is removed by the bobbin holder, the elastic force of the torsion spring causes the gripper to automatically reset, preparing for the next yarn bobbin gripping. This design improves the versatility and adaptability of the gripping unit, reduces the probability of operational failures due to differences in yarn bobbin specifications, and enhances the applicability of the automatic bobbin dropping device to different production needs.

[0014] In a structure that optimizes the aforementioned solution, side stops are also included, which are movably disposed on both sides of the front end of the housing. Specifically, one end of the side stop is rotatably fixed, and the other end is fixed through an arc-shaped groove, allowing the side stop to rotate within a certain range around the fixed point. The two side stops then block the yarn bobbin to be retrieved from the side, fixing it in the correct position. When the yarn bobbin storage mechanism is pushed to the position of the bobbin holder, the side stops are pushed open by the clamping plates on the bobbin holder, allowing the bobbin holder to smoothly clamp the yarn bobbin to be retrieved.

[0015] Specifically, the side stop is installed between the lower and upper housings, with one end fixed and the other end fixed by an arc-shaped groove.

[0016] The side stop blocks limit the movement of the yarn bobbin from the side, forming a comprehensive fixation with the grippers and clamps in all directions, further improving the stability of the yarn bobbin during movement and effectively preventing lateral shifting or wobbling, ensuring that the yarn bobbin is always in the accurate position. Simultaneously, the movable design of the side stop blocks allows them to be smoothly pushed aside by the clamping plates on the bobbin rack when the yarn bobbin storage mechanism is docked with the bobbin rack, without affecting the bobbin rack's gripping of the yarn bobbin. This ensures the smoothness and efficiency of the bobbin dropping operation, making the yarn bobbin handover process more stable and reliable.

[0017] In a structure that optimizes the aforementioned solution, a backstop block is also included, which is installed on the lower part of the upper housing.

[0018] Specifically, four anti-reverse blocks are distributed in the lower part of the upper shell, arranged in pairs in the middle and rear of the upper shell. The two rows of anti-reverse blocks on the upper shell can only rotate in the direction of yarn bobbin pushing. When the yarn bobbin moves in the opposite direction, it will be blocked by the anti-reverse blocks, thus preventing the yarn bobbin to be retrieved and the spare yarn bobbin from being pushed out of the yarn bobbin storage mechanism due to inertia when the yarn bobbin storage mechanism moves and stops.

[0019] During the movement and stopping of the yarn bobbin storage mechanism, the yarn bobbin may tend to move backward due to inertia, causing it to exit the housing or become misaligned. The anti-reverse block effectively prevents the yarn bobbin from moving in the opposite direction. Its unidirectional rotation allows the yarn bobbin to move normally in the pushing direction, while forming a blockage in the reverse direction, ensuring stable storage of the yarn bobbin within the housing. This ensures that each yarn bobbin is accurately positioned in the gripping unit's working position, preventing abnormal yarn bobbin positioning from affecting the bobbin dropping operation, improving the reliability and stability of the automatic bobbin dropping device, and guaranteeing the continuity and accuracy of the texturing machine's production.

[0020] Compared to existing technologies, the automatic bobbin feeding device for texturing machines described in this utility model is fully automated, with all components working together to achieve automatic conveying and precise delivery of empty yarn bobbins, thereby improving production efficiency. Specific beneficial effects are as follows:

[0021] The automatic bobbin dropping device for the texturing machine described in this utility model achieves automatic conveying and precise delivery of empty bobbins through the coordinated operation of components such as cylinders, swing arms, guide rails, and bobbin storage mechanisms. This replaces traditional manual loading and unloading, reduces operational steps, seamlessly connects to winding operations, significantly improves production efficiency, and meets the needs of large-scale continuous production. Automated bobbin dropping reduces the labor intensity of operators, reduces manpower input, alleviates labor cost pressure, and lowers operating costs. It avoids equipment failures and safety accidents caused by manual operation, ensuring personnel safety and equipment stability. Precise positioning of the stop rod, assisted reset by the return spring, and the lever-based connection between the cylinder and swing arm ensure stable and controllable action. The gripping unit, side stops, and anti-reverse blocks fix the bobbin in all directions, ensuring accurate and stable handover, improving bobbin dropping reliability and product quality. The rotatable grippers, combined with torsion springs, allow the gripping unit to adapt to different bobbin specifications, reducing the probability of failure and enhancing the device's adaptability. A reasonable shell structure, roller arrangement, and return spring design optimize the overall structure, lower the center of gravity, extend cylinder life, ensure long-term stable operation of the device, and reduce maintenance costs.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] The core structure of the automatic yarn bobbin dropping device for the texturing machine described in this utility model includes a yarn bobbin storage mechanism 1, a guide rail 2, a swing arm 3, a rotating shaft 4, a cylinder 5, and optimized components such as a reset spring 6 and a stop rod 8. The guide rail 2 is horizontally fixed to the wall plate 7. The yarn bobbin storage mechanism 1 is slidably connected to the guide rail 2 via a first set of rollers 103 on both sides of the lower housing 101, allowing it to move freely along the guide rail. The swing arm 3 is hinged to the wall plate 7 via the rotating shaft 4, and its end has a long groove, forming a linkage structure with the second set of rollers 103 of the yarn bobbin storage mechanism 1. The cylinder 5 is fixed to the wall plate 7, and the connection point between its actuating end and the swing arm 3 is located below the rotating shaft 4. It utilizes the lever principle to drive the swing arm to swing, thereby realizing the pushing out and resetting of the yarn bobbin storage mechanism 1. The yarn bobbin storage mechanism 1 is composed of an upper housing 102 and a lower housing 101 connected by a connecting piece 104, and its interior can accommodate the yarn bobbin awaiting loading. Two empty yarn tubes, yarn tube 901 and rear spare yarn tube 902, are taken. The front gripping unit includes two clamping plates 108 of the upper housing 102 and two grippers 105 of the lower housing 101, which are mounted on a torsion spring base and can rotate around the base to adapt to yarn tubes of different specifications. Side stops 107 are provided on both sides of the front end of the housing, with one end fixed to the housing and the other end movably connected through an arc-shaped long groove to form a lateral limit. The lower part of the upper housing 102 is provided with two rows of stop blocks 106, one in the middle and one in the rear, which only allow the yarn tube to move in the pushing direction and prevent the yarn tube from exiting the housing in the reverse direction. In the auxiliary optimization structure, one end of the return spring 6 is fixed to the wall plate 7 and the other end is connected to the swing arm 3 to provide auxiliary elastic force for the swing arm to return. The stop rod 8 is vertically fixed to the wall plate 7 and cooperates with the limiting part of the yarn tube storage mechanism 1 to ensure that it stops accurately when it moves to the docking position of the bobbin rack.

[0036] The automatic bobbin unloading process of this utility model achieves full automation through the coordinated action of various components. Specifically, in the initial state, the bobbin storage mechanism 1 is in the reset position. The front "bobbin to be retrieved" is held vertically by the gripper 105 and clamping plate 108, and laterally fixed by the side stop block 107. The rear spare bobbin 902 is limited by the anti-reverse block 106 and awaits winding. When a full bobbin is retrieved, the cylinder 5 retracts, pulling the swing arm 3 downwards around the rotation axis 4. This, along with the second set of rollers 103, drives the bobbin storage mechanism 1 to move along the guide rail 2 towards the bobbin rack. When it reaches the predetermined position, the stop rod 8 contacts the limiting part for precise positioning. When the bobbin rack's clamping plate contacts the bobbin, it pushes open the side stop block 107. Simultaneously, the gripper 105 rotates around the base under force, releasing the bobbin from the clamping plate 108. The bobbin rack then grabs the bobbin to be retrieved 902. 01. The yarn bobbin is fed into the winding device. After the yarn bobbin handover is completed, the cylinder 5 extends to push the swing arm 3 to rotate upward and reset. The reset spring 6 assists in accelerating the reset and stabilizing the swing arm position. The rear spare yarn bobbin 902 moves forward under the action of manual replenishment. The anti-reverse block 106 allows it to move along the pushing direction and be repositioned as a new yarn bobbin 901 to be picked up. During the process, the torsion spring design of the gripper 105 fits the yarn bobbins of different diameters to ensure stable clamping. The arc-shaped long groove of the side stop block 107 is passively pushed open during docking and restricts lateral displacement during movement. The one-way blocking of the anti-reverse block 106 prevents the yarn bobbin from moving backward due to inertia. Through the coordination of the above structure and action, the device realizes the full-process automation of "full bobbin removal → automatic conveying of empty yarn bobbins → precise docking → reset and replenishment", which significantly improves the production efficiency and stability of the texturing machine.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
