Description

Technical Field

[0001] This invention relates to the technical field of textile tools, and in particular to a non-rotating automatic shuttle winding device and method for textile use. Background Technology

[0002] In the textile weaving industry, the plate shuttle is the core weft insertion component of a shuttle loom. Before weaving, the weft yarn needs to be evenly and tightly wound onto the plate shuttle. This process is called shuttle winding.

[0003] In related technologies, shuttle winding is usually accomplished manually. However, this method is not only inefficient, but also results in inconsistent shuttle winding quality.

[0004] Therefore, there is an urgent need to provide a non-rotating automatic shuttle device and method for textiles to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a non-rotating automatic shuttle winding device and method for textiles, which can improve both production efficiency and shuttle winding quality.

[0006] In a first aspect, embodiments of the present invention provide a non-rotating automatic shuttle winding device for textiles, comprising a shuttle winding platform, a yarn supply mechanism, and a moving actuator, a yarn guiding and reversing mechanism, a tension compensation mechanism, a clamping and cutting mechanism, and a control mechanism disposed on the shuttle winding platform. The control mechanism is electrically connected to the moving actuator, the yarn guiding and reversing mechanism, and the clamping and cutting mechanism, respectively, wherein: The yarn supply mechanism is used to provide the yarn required for the shuttle winding; The mobile actuator is provided with a plate-shaped shuttle, which is used to drive the plate-shaped shuttle to perform reciprocating linear motion along its axial direction; The yarn guiding mechanism is equipped with a yarn guiding component. The yarn guiding mechanism is used to pull the yarn during the reciprocating linear motion of the plate shuttle, and to drive the yarn guiding component to switch positions when the plate shuttle moves to the end of its stroke, so as to change the yarn drop position on the plate shuttle. The tension compensation mechanism is used to keep the yarn in a constant tension state during the reciprocating linear motion of the plate shuttle, so that the yarn is tightly and stably wound on the plate shuttle. The clamping and cutting mechanism is used to clamp and cut the yarn after the shuttle has reached a preset number of turns, so as to complete the complete shuttle operation. The control mechanism is used to control the actions of the moving actuator, the yarn guiding and reversing mechanism, and the clamping and cutting mechanism.

[0007] Secondly, embodiments of the present invention provide a non-rotating automatic shuttle winding method for textiles, employing the aforementioned apparatus, comprising: Step S1: The yarn is drawn out from the yarn supply mechanism, guided sequentially through the yarn guide net, the tension compensation mechanism and the yarn reversing mechanism, and the yarn end is fixed to one end of the plate shuttle; Step S2: Start the control mechanism and control the servo motor to drive the plate shuttle to move linearly along its axis toward the first stroke end point, so that the yarn forms an oblique arrangement in the first direction on the surface of the plate shuttle; Step S3: When the plate shuttle moves to the end of the first stroke, control the drive to drive the yarn guide to switch positions, so as to change the yarn drop position on the plate shuttle. Step S4: Control the servo motor to drive the plate shuttle to move in the opposite direction along the axial direction to the second stroke end point, so that the yarn forms an oblique arrangement on the surface of the plate shuttle opposite to the first direction; Step S5: Repeat steps S2 to S4 to make the yarn form a continuous alternating S-shaped arrangement track on the surface of the plate shuttle, thereby realizing the automatic shuttle winding of the plate shuttle in a non-rotating state. Step S6: After the shuttle has completed the preset number of turns, control the clamping and cutting mechanism to clamp and cut the yarn to complete the shuttle operation.

[0008] This invention provides a non-rotating automatic shuttle winding device and method for textiles. A movable actuator drives a plate-shaped shuttle to reciprocate linearly along its axis. At the endpoint of the motion, a yarn guiding mechanism drives a yarn guide component to perform a step-by-step position switch, thereby changing the yarn landing point and causing the yarn to form a continuous, alternating S-shaped arrangement trajectory on the surface of the plate-shaped shuttle. This results in uniform shuttle winding, improved winding quality, and automatic shuttle winding of the plate-shaped shuttle in a non-rotating state. Simultaneously, a tension compensation mechanism dynamically compensates for yarn length changes during reversal and acceleration / deceleration phases. After the shuttle has completed a preset number of turns, a control mechanism controls a clamping and cutting mechanism to clamp and cut the yarn, thus completing one full shuttle winding operation. This device can achieve uniform and efficient winding of multiple yarns, and has advantages such as simple structure, high degree of automation, and stable shuttle winding quality. It can significantly improve shuttle winding efficiency and reduce manual operation intensity. Therefore, the above technical solution can improve both production efficiency and shuttle winding quality. Attached Figure Description

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 5 As shown, this embodiment of the invention provides a non-rotating automatic shuttle device for textiles. The device includes a shuttle platform 1, a yarn supply mechanism 2, and a moving actuator 3, a yarn guiding and reversing mechanism 4, a tension compensation mechanism 5, a clamping and cutting mechanism 6, and a control mechanism 7, all mounted on the shuttle platform 1. The control mechanism 7 is electrically connected to the moving actuator 3, the yarn guiding and reversing mechanism 4, and the clamping and cutting mechanism 6, respectively. Yarn supply mechanism 2 is used to provide the yarn required for the shuttle winding; The movable actuator 3 is provided with a plate-shaped shuttle 31, which is used to drive the plate-shaped shuttle 31 to perform reciprocating linear motion along its axis. The yarn guiding mechanism 4 is provided with a yarn guiding component 41. The yarn guiding mechanism 4 is used to pull the yarn during the reciprocating linear motion of the plate shuttle 31, and to drive the yarn guiding component 41 to switch positions when the plate shuttle 31 moves to the end of the stroke, so as to change the drop position of the yarn on the plate shuttle 31. The tension compensation mechanism 5 is used to keep the yarn in a constant tension state during the reciprocating linear motion of the plate shuttle 31, so that the yarn is tightly and stably wound on the plate shuttle 31. The clamping and cutting mechanism 6 is used to clamp and cut the yarn after the shuttle has reached a preset number of turns, so as to complete the complete shuttle operation; The control mechanism 7 is used to control the movement of the moving actuator 3, the yarn guiding and reversing mechanism 4, and the clamping and cutting mechanism 6.

[0014] In this embodiment, the moving actuator 3 drives the plate shuttle 31 to reciprocate linearly along its axis. At the endpoint of the motion, the yarn guiding mechanism 4 drives the yarn guiding component 41 to perform step-by-step position switching, thereby changing the yarn landing point position. This causes the yarn to form a continuous alternating S-shaped arrangement trajectory on the surface of the plate shuttle 31, resulting in uniform yarn winding and improved winding quality. This enables the plate shuttle 31 to automatically wind in a non-rotating state. Simultaneously, a tension compensation mechanism 5 dynamically compensates for yarn length changes during reversal and acceleration / deceleration phases. After the preset number of turns is reached, the control mechanism 7 controls the clamping and cutting mechanism 6 to clamp and cut the yarn, thus completing one complete winding operation. This device can achieve uniform and efficient winding of multiple yarns, and has advantages such as simple structure, high degree of automation, and stable winding quality. It can significantly improve winding efficiency and reduce manual operation intensity. Therefore, the above technical solution can improve both production efficiency and winding quality.

[0015] In one embodiment of the present invention, the shuttle platform 1 is provided with at least two shuttle stations, and each shuttle station is provided with a set of moving actuators 3, a set of yarn guiding and reversing mechanisms 4, a set of tension compensation mechanisms 5 and a set of clamping and cutting mechanisms 6.

[0016] In this embodiment, two shuttle stations are symmetrically arranged along the central axis of the shuttle platform 1 to achieve shuttle operations that run alternately or synchronously, thereby improving shuttle efficiency.

[0017] In one embodiment of the present invention, the yarn supply mechanism 2 includes a frame 21 and a plurality of yarn tubes 22 disposed on the frame 21, wherein the yarn on the yarn tubes 22 is axially exited.

[0018] In one embodiment of the present invention, the clamping and cutting mechanism 6 includes two clamping members 61 and a cutting tool 62 disposed between the two clamping members 61. Both the clamping members 61 and the cutting tool 62 are electrically connected to the control mechanism 7. The two clamping members 61 are used to clamp the yarn, and the cutting tool 62 is used to cut the clamped yarn.

[0019] In one embodiment of the present invention, the tension compensation mechanism 5 is at least two sets. Each set of tension compensation mechanism 5 includes a first fixed frame 51 disposed on the shuttle platform 1, a guide rod 52 rotatably disposed on the first fixed frame 51, a torsion spring 53 sleeved on the guide rod 52, and a fixing member 54 disposed on the guide rod 52 and fixing the short leg of the torsion spring 53. The long leg of the torsion spring 53 is provided with a yarn guide eye, through which the yarn can pass.

[0020] In this embodiment, the tension compensation mechanism 5 is used to tighten and compensate for excess yarn when the yarn becomes slack due to excess length during the reciprocating motion and acceleration / deceleration of the plate shuttle. This ensures the yarn remains at a constant tension and is tightly and stably wound around the plate shuttle. When the yarn experiences length changes or tension fluctuations due to the reciprocating action of the torsion spring's elastic energy storage and release, the yarn length changes are offset in real time (i.e., dynamic compensation for yarn length changes) to maintain constant yarn tension. The two sets of tension compensation mechanisms 5, compared to a single set, can significantly increase the amount of yarn compensation, thus better offsetting yarn length changes.

[0021] In one embodiment of the present invention, a yarn guide net 8 is also provided on the shuttle platform 1. The yarn guide net 8 is a grid structure used to separate, position, guide, and constrain multiple strands of yarn to prevent the yarns from tangling together.

[0022] In one embodiment of the present invention, the mobile actuator 3 includes a mobile slide rail 32 disposed on the shuttle platform 1, a linear module 33 disposed on the mobile slide rail 32, and a servo motor 34 electrically connected to the linear module 33 and the control mechanism 7 respectively. The plate shuttle 31 is disposed on the linear module 33 and is used to realize the reciprocating linear motion of the plate shuttle 31 within a preset stroke range.

[0023] In some embodiments, the plate shuttle 31 is fixed to the linear module 33 by a fixing component that can limit the circumferential rotation of the plate shuttle 31, so that the plate shuttle 31 remains in a non-rotating state during the shuttle process.

[0024] In one embodiment of the present invention, the yarn guiding reversing mechanism 4 includes a second fixed frame 42 disposed on the shuttle platform 1 and a driving member 43 disposed on the second fixed frame 42. The yarn guiding member 41 is disposed at the end of the driving member 43. The driving member 43 is electrically connected to the control mechanism 7. The driving member 43 can drive the yarn guiding member 41 to move back and forth along the direction of movement perpendicular to the plate shuttle 31, so as to realize the position switching of the yarn guiding member 41.

[0025] Furthermore, embodiments of the present invention also provide a non-rotating automatic shuttle winding method for textiles, employing the apparatus mentioned in the above embodiments, the method comprising: Step S1: The yarn is drawn out from the yarn supply mechanism 2 and guided through the yarn guide net 8, tension compensation mechanism 5 and yarn guide reversal mechanism 4 in sequence, and the end of the yarn is fixed to one end of the plate shuttle 31. Step S2: Start the control mechanism 7 and control the servo motor 34 to drive the plate shuttle 31 to move linearly along its axis toward the first stroke end point, so that the yarn forms an oblique arrangement in the first direction on the surface of the plate shuttle 31. Step S3: When the plate shuttle 31 moves to the end of the first stroke, the control drive 43 drives the yarn guide 41 to switch positions, so as to change the yarn drop position on the plate shuttle 31. Step S4: Control the servo motor 34 to drive the plate shuttle 31 to move in the opposite direction along the axial direction to the second stroke end point, so that the yarn forms an oblique arrangement on the surface of the plate shuttle 31 opposite to the first direction; Step S5: Repeat steps S2 to S4 to make the yarn form a continuous alternating S-shaped arrangement track on the surface of the plate shuttle 31, thereby realizing the automatic shuttle winding of the plate shuttle 31 in a non-rotating state. Step S6: After the shuttle has completed the preset number of turns, control the clamping and cutting mechanism 6 to clamp and cut the yarn to complete the shuttle operation.

[0026] It is understood that the non-rotating automatic shuttle method for textiles provided in this embodiment and the non-rotating automatic shuttle device for textiles provided in the above embodiments are based on the same inventive concept, and therefore have the same beneficial effects. The beneficial effects of the non-rotating automatic shuttle method for textiles will not be elaborated here.

[0027] In one embodiment of the present invention, during the shuttle process, the control mechanism 7 sets parameters for the movement speed, acceleration and travel range of the plate shuttle 31 to adjust different shuttle densities and the number of shuttle turns.

[0028] The following is combined Figure 5 This section introduces the shuttle winding principle of an automatic shuttle device.

[0029] During the shuttle-turning stage, the control mechanism 7 is activated, driving the servo motor 34 in the moving actuator 3 to move. This, via the linear module 33, propels the plate shuttle 31 (the wooden shuttle in the diagram) linearly along the axial direction ① towards the first stroke endpoint. During the movement of the plate shuttle 31, the yarn forms an oblique arrangement in the first direction on its surface. When the plate shuttle 31 reaches the first stroke endpoint, the control mechanism 7 controls the drive component 43 in the yarn guiding mechanism 4 to switch positions, moving the yarn guide component 41 along direction ②, thereby changing the yarn's drop position on the plate shuttle 31. Subsequently, the control mechanism 7 drives the moving actuator 3 to move the plate shuttle 31 linearly in the opposite direction ③ towards the second stroke endpoint, causing the yarn to form an oblique arrangement on the surface of the plate shuttle 31 opposite to the first direction. When the plate shuttle 31 reaches the second stroke endpoint, the control mechanism 4 is again controlled to switch the yarn guide position, moving it along direction ④. The plate-shaped shuttle 31 continuously reciprocates linearly between two endpoints, switching the yarn guide position each time it reaches an endpoint, causing the yarn to gradually form a continuous, alternating S-shaped pattern on the surface of the plate-shaped shuttle 31. During the shuttle winding process, when the plate-shaped shuttle 31 is accelerating, decelerating, or changing direction, the torsion spring 53 (i.e., the yarn replenishment spring) in the tension compensation mechanism 5 dynamically compensates for changes in yarn length through torsional deformation, thereby maintaining the relative stability of the yarn tension and allowing the yarn to be tightly and evenly wound on the surface of the plate-shaped shuttle 31.

[0030] In the final stage, after the shuttle has completed the preset number of turns or the preset length, the control mechanism 7 controls the clamping and cutting mechanism 6 to operate. First, two clamping members 61 clamp and fix the yarn, and then the cutting tool 62, located between the two clamping members 61, cuts the yarn, thus completing one complete board shuttle winding operation. When the device adopts a dual-station shuttle winding structure, the control mechanism 7 can control the two shuttle winding stations to operate alternately or synchronously according to production needs. This allows one station to perform shuttle winding operations while the other station can perform shuttle loading or unloading operations, thereby improving the overall operating efficiency and production efficiency of the equipment.

[0031] Through the above implementation method, the present invention can achieve automatic yarn winding without driving the plate shuttle to rotate, through the axial reciprocating motion of the plate shuttle and the coordinated action of the yarn guiding and reversing mechanism, and maintain the stability of yarn tension through the tension compensation mechanism, so that the yarn forms a regular arrangement on the surface of the plate shuttle, thereby realizing the automated and high-efficiency winding operation of the plate shuttle.
