Description

Technical Field

[0001] This invention relates to the field of textile yarn technology, and more particularly to a smart splicing device for yarn-dyed warp yarns. Background Technology

[0002] Yarn-dyed fabric is a weaving technique that uses yarns of multiple colors interwoven to create a multi-colored fabric. Yarn-dyed fabrics can exhibit a rich variety of textures and patterns through various weaving methods and pattern designs, resulting in unique artistic effects. The main difference between yarn-dyed fabric and other manufacturing methods lies in the use of multiple colored yarns to create this vibrant effect. Other weaving methods typically produce monochrome fabrics or use yarn materials without involving the interweaving of multiple colors. Therefore, yarn-dyed fabrics often have a greater visual impact and artistic appeal.

[0003] A warp splice is a special treatment used to connect two warp yarns during weaving on a loom. On a loom, warp yarns are yarns that pass laterally through the weft yarns; they need to remain continuous during weaving to ensure the integrity and quality of the fabric. The purpose of a warp splice is to prevent breaks or gaps during weaving, thereby ensuring the uniformity and quality of the fabric.

[0004] The prior art CN113699626A discloses an automatic yarn splicing device and method, which uses components such as a lifting unit, a suction unit, and a drafting unit to splice the two ends of the yarn by moving the drafting roller. However, after splicing, the fiber fineness and color at the break point cannot be determined. Since the yarn-dyed yarn has already undergone a dyeing process before weaving, and skips the dyeing process after weaving, the fiber fineness and color at the splicing point of the yarn-dyed warp yarn cannot be determined after the break point is spliced, which seriously affects the yarn-dyed effect.

[0005] Therefore, it is necessary to improve the existing yarn-dyed warp splicing device to solve the above problems. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides an intelligent splicing device for yarn-dyed warp yarns, aiming to solve the defect in the prior art that the fiber fineness and color at the break joint of yarn-dyed warp yarns cannot be determined.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an inductive unit, an adjustment unit fixedly connected to the inductive unit, a plurality of clamping units disposed on the inductive unit and the adjustment unit, and a processing unit disposed on the inductive unit, the adjustment unit and the clamping unit respectively.

[0008] The clamping units are used to clamp the warp yarn breakage, and enable the two ends of the breakage to move and rotate while being clamped, so that the two ends can move and rotate for twisting in the induction unit and the adjustment unit. The clamping units are coaxially arranged, and the clamping units can rotate forward and reverse respectively.

[0009] The inductive unit is used to blow air onto the two broken ends, causing the yarn strands on the two broken ends to spread out after they are charged with the same type of charge. The inductive unit is connected to the processing unit and can output positive and negative charges respectively.

[0010] The adjustment unit is equipped with a visual detection unit, which can detect the color and thickness of the yarn and the broken ends after they are joined together, and send the detection data to the processing unit. The processing unit controls the clamping unit to rotate and move based on the detection data until the thickness and color of the joined ends match the yarn.

[0011] In a preferred embodiment of the present invention, the clamping unit includes a moving unit and a rotating unit. The moving unit is used to drive the broken end to move horizontally, and the rotating unit is used to drive the broken end to rotate. Both the moving unit and the rotating unit are fixedly connected to the yarn.

[0012] In a preferred embodiment of the present invention, each end of the broken piece is provided with at least one of the rotating units and one of the moving units.

[0013] In a preferred embodiment of the present invention, the rotating unit on each severed end is disposed between the moving unit and the severed end, and the moving unit is disposed on one side of the rotating unit.

[0014] In a preferred embodiment of the present invention, the inductive unit is provided with a plurality of air sources and blows air in opposite directions, with the two ends located between adjacent air sources.

[0015] In a preferred embodiment of the present invention, each yarn with a broken end is provided with a charge detection unit, which is used to detect the charge value on the yarn.

[0016] To achieve the above objectives, the second technical solution adopted by the present invention is: a method for using the intelligent splicing device for yarn-dyed warp yarns, which includes the following steps:

[0017] S1: The two severed ends are clamped by the clamping unit, and the clamping device sends the two severed ends to the inductive unit;

[0018] S2: The inductive unit blows air onto both ends of the broken ends and causes both ends to carry the same charge. The multiple strands of wire on the broken ends spread out. The clamping unit moves the two ends of the broken ends closer together so that there is an overlapping part between the two ends of the broken ends.

[0019] S3: The inductive unit blows air onto the two broken ends. The air-blown charge is opposite to the charge in S2. When the multiple strands of wire at the ends are aggregated, the clamping unit rotates the two broken ends relative to each other, and the two broken ends are joined together. The joint is then sent to the adjustment unit.

[0020] S4: The adjustment unit detects the fiber fineness and color at the joint of the broken ends. After the processing unit calculates the detection results, it controls the clamping unit to rotate in the opposite direction to the rotation in S3 and moves the broken ends. After the rotation is completed, it rotates in the same direction as S2 so that the two ends of the joint are rejoined.

[0021] S5: The adjustment unit re-detects the fiber fineness and color, and repeats step S4 until the fiber fineness and color at the break joint are consistent with the yarn.

[0022] In a preferred embodiment of the present invention, the blowing method in S2 is counter-current blowing, and the two ends are located at the convection point of the counter-current blowing.

[0023] In a preferred embodiment of the present invention, the direction of the broken end rotation in S3 is consistent with the yarn twist direction, and the number of twists at the broken end joint is consistent with the number of yarn twists.

[0024] In a preferred embodiment of the present invention, the direction and degree of movement in S4 are related to the fineness of the joint. If the fiber fineness at the joint is too large, the two broken ends will move in opposite directions; if the fiber fineness at the joint is too small, the two broken ends will move in opposite directions.

[0025] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0026] (1) The present invention provides a smart splicing device for yarn-dyed warp yarns. By using components such as a clamping unit, an induction unit, an adjustment unit and a processing unit, the yarn-dyed warp yarn ends are first induction and then repeatedly adjusted in terms of thickness and color, so that the fineness and color of the yarn-dyed warp yarn ends are consistent with the fineness and color of the warp yarns. Compared with the existing warp yarn ends splicing device, it can improve the consistency between the ends and the yarn fibers, and has adjustability and applicability. It solves the defect of the existing yarn-dyed warp yarn splicing device that cannot determine the fiber fineness and color of the ends.

[0027] (2) In this invention, the inductive unit enables the yarn ends at both ends to be blown and charged simultaneously. Under the blowing and charging steps, the multiple strands of yarn on the yarn ends are dispersed, and static electricity is removed after the ends overlap. The strands can be tightly attached. Compared with the prior art, it can improve the overlap rate of yarn ends and increase the winding ability between yarns. When the yarn ends are joined, they can have a tighter bonding ability, which improves the firmness and bonding efficiency of the yarn ends.

[0028] (3) In this invention, the rotating unit and the moving unit cooperate with each other to enable the broken ends to move and rotate simultaneously. When the yarn broken ends are joined, the fineness can be adjusted. The rotating unit is located between the moving unit and the broken end, which can avoid the rotating unit from affecting the twist of the yarn when rotating the joint. Compared with the prior art, it can improve the accuracy of the yarn adjustment process and maintain the twist of the yarn, thus improving the stability of the yarn performance.

[0029] (4) In this invention, the visual detection on the adjustment unit detects the fineness and color of the joint of the broken ends, and the yarn is moved and rotated by the clamping unit to repeatedly untwist and twist the joint of the broken ends, so that the fineness and color of the joint of the broken ends are consistent with the fineness and color of the yarn. Compared with the prior art, the fineness and color of the joint can be adjusted during the repeated untwist and twist process, which improves the consistency between the joint of the broken ends and the yarn, and can increase the friction between the yarns at the joint, thereby enhancing the strength of the broken ends joint.

[0030] (5) In this invention, the inductive unit causes the two ends of the broken wire to carry the same charge. After the broken wire at each end is unfolded, the two ends of the broken wire are evenly staggered and aligned under the repulsion of the same charge when they are joined. When they are joined, the two ends of the broken wire can be evenly wrapped. Compared with the prior art, it can improve the uniformity of the unfolding of the wire when the broken wire is joined, improve the strength of the broken wire joint, and avoid the broken wire joint from breaking again in subsequent processing.

Obviously, the drawings described below are only some embodiments recorded in the present invention.

[0037] 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 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.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1 As shown, the intelligent splicing device for yarn-dyed warp includes: an induction unit 310, an adjustment unit 320 fixedly connected to the induction unit 310, a plurality of clamping units 200 disposed on the induction unit 310 and the adjustment unit 320, and a processing unit disposed on the induction unit 310, the adjustment unit 320 and the clamping units 200 respectively.

[0040] Several clamping units 200 are used to clamp the warp yarn ends, allowing both ends to move and rotate while being clamped. This enables the ends to move and rotate within the induction unit 310 and adjustment unit 320 for twisting. The clamping units 200 are coaxially arranged and can rotate clockwise and counterclockwise respectively. The clamping units 200 align the ends, ensuring coaxial alignment and improving yarn alignment efficiency.

[0041] The induction unit 310 is used to blow air onto the two broken ends, causing the yarn strands on the broken ends to spread out under the same charge. The induction unit 310 is connected to the processing unit and can output positive and negative charges respectively. When blowing air, it can disperse the yarn wrapped around the broken ends and make the yarn spread out evenly under the action of charge.

[0042] The induction unit 310 enables the yarn ends at both ends to be blown and charged simultaneously. During the blowing and charging process, the multiple strands of yarn on the yarn ends separate and remove static electricity after the ends overlap. The strands can be tightly bonded, which can improve the overlap rate of the yarn ends and increase the entanglement ability between the yarns. When the yarn ends are joined, they can have a tighter bonding ability, which improves the firmness and efficiency of the yarn end bonding.

[0043] The adjustment unit 320 is equipped with a visual inspection unit, which can detect the color and thickness of the yarn and the joined ends separately, and send the detection data to the processing unit. The processing unit controls the clamping unit 200 to rotate and move according to the detection data until the thickness and color of the joined ends match the yarn. The adjustment unit 320 can adjust the fineness and color of the joined ends to match the fineness and color of the yarn, ensuring the consistency of the colored yarn color. In the prior art, when the joined ends are re-dyed, the color will be different due to the difference in fineness, which will still result in poor color effect of the colored yarn fabric. The visual inspection unit can detect the fiber fineness using a fully automatic fiber fineness meter and the fiber color using a spectrophotometer. The fully automatic fiber fineness meter and the spectrophotometer do not interfere with each other during use.

[0044] The clamping unit 200 includes a moving unit 220 and a rotating unit 230. The moving unit 220 is used to drive the broken yarn to move horizontally, and the rotating unit 230 is used to drive the broken yarn to rotate. Both the moving unit 220 and the rotating unit 230 are fixedly connected to the yarn, and the moving unit 220 and the rotating unit 230 operate separately. The moving unit 220 can be a drafting device to draft the yarn and move it; the rotating unit 230 can be a twisting roller or a twisting wheel, which fixes the yarn and drives the yarn to rotate to complete twisting or untwisting.

[0045] The rotating unit 230 at each end of the broken yarn is positioned between the moving unit 220 and the broken yarn, with the moving unit 220 located on one side of the rotating unit 230. Each end of the broken yarn has at least one rotating unit 230 and one moving unit 220. Through the cooperation of the rotating unit 230 and the moving unit 220, the broken yarn can move and rotate simultaneously, allowing for fineness adjustment during yarn breakage. Furthermore, the rotating unit 230's position between the moving unit 220 and the broken yarn prevents it from affecting the yarn twist when rotating the joint, improving the accuracy of yarn adjustment and maintaining yarn twist, thus enhancing yarn performance stability.

[0046] The inductive unit 310 is equipped with several air sources that blow air in opposite directions, with the two broken ends located between adjacent air sources. The opposing airflow causes the two air streams to collide and generate a backflow. The backflow direction is opposite to the direction of the broken ends, and the backflow continuously acts on the broken ends to ensure that the broken threads unravel.

[0047] Each broken end of the yarn is equipped with a charge detection unit, which measures the amount of charge on the yarn. This unit ensures that the charge at both ends remains consistent and eliminates the charge on the yarn after static electricity is neutralized, preventing excessive static electricity from affecting subsequent processing. The charge detection unit functions as a fabric charge tester; the yarn can be briefly grounded before testing.

[0048] like Figure 2 As shown, to achieve the above objectives, the second technical solution adopted by the present invention is: a method for using the intelligent splicing device for yarn-dyed warp yarns, which includes the following steps based on the intelligent splicing device for yarn-dyed warp yarns:

[0049] S1: Clamp both ends of the broken piece using clamping unit 200, and the clamping device sends both ends of the broken piece to inductive unit 310;

[0050] S2: The induction unit 310 blows air onto the two broken ends and causes the two ends to carry the same charge. The multiple strands of wire on the broken ends spread out, and the clamping unit 200 moves the two broken ends closer together so that the two broken ends overlap.

[0051] The inductive unit 310 causes the two ends of the broken wire to carry the same charge. After the broken wire is unfurled at each end, the two ends of the broken wire are evenly staggered and aligned under the repulsion of the same charge when they are joined. This allows the two ends of the broken wire to be evenly wrapped during the joining process, which can improve the uniformity of the unfurling of the wire and increase the strength of the joint. This prevents the joint from breaking again during subsequent processing.

[0052] S3: The induction unit 310 blows air onto the two broken ends. The air-blown charge is opposite to the charge in S2. When the multiple strands of wire at the ends are aggregated, the clamping unit 200 rotates the two broken ends relative to each other, and the two broken ends are joined together. The joint is then sent to the adjustment unit 320.

[0053] S4: The adjustment unit 320 detects the fiber fineness and color at the joint of the broken ends. After the processing unit calculates the detection results, it controls the clamping unit 200 to rotate in the opposite direction to the rotation in S3 and moves the broken ends. After the rotation is completed, it rotates in the same direction as S2 so that the two ends of the joint are rejoined.

[0054] S5: The adjustment unit 320 re-detects the fiber fineness and color, and repeats step S4 until the fiber fineness and color at the break joint are consistent with the yarn.

[0055] The visual inspection unit 320 detects the fineness and color of the joint at the broken ends, and adjusts the yarn by moving and rotating it through the clamping unit 200. The joint at the broken ends is repeatedly untwisted and twisted, so that the fineness and color of the joint at the broken ends are consistent with the fineness and color of the yarn. The fineness and color of the joint can be adjusted during the repeated untwisting and twisting process, which improves the consistency between the joint at the broken ends and the yarn, and increases the friction between the yarns at the joint, thereby enhancing the strength of the broken ends.

[0056] The air blowing method in S2 is counter-current blowing, with the two ends located at the convection points of the counter-current blowing. The airflow can be direct or spiral, with the spiral airflow direction opposite to the yarn twist direction. The blowing device used can be an ion fan.

[0057] In S3, the direction of the broken end rotation is consistent with the yarn twist direction, and the number of twists at the broken end joint is consistent with the number of twists in the yarn. Maintaining consistency in the number of twists and the twist direction ensures that the broken end, after being joined, has a consistent appearance with the yarn, guaranteeing the consistency of the yarn-dyed warp yarns.

[0058] The direction and degree of movement in S4 are related to the fineness of the joint. If the fiber fineness at the joint is too large, the two broken ends will move away from each other; if the fiber fineness at the joint is too small, the two broken ends will move towards each other. The separate operation of the moving unit 220 and the rotating unit 230 ensures the precision of the adjustment.

[0059] Example 1

[0060] like Figure 3 and Figure 4 As shown, a smart splice structure for yarn-dyed warp yarns includes: a frame 100, and a plurality of clamping units 200 disposed on the frame 100.

[0061] The frame 100 is provided with a fiber cavity for fiber passage. Several guide rails are provided on the inner wall of the fiber cavity, and these guide rails are fixedly connected to clamping units 200. A moving motor is mounted on each guide rail, driving the clamping units 200 to move along the guide rails. All guide rails are horizontally arranged and located on the same horizontal plane, and the clamping units 200 are coaxially arranged with the fiber cavity.

[0062] An inductive unit 310 and an adjustment unit 320 are fixedly mounted on the fiber cavity, respectively, and are located on both sides of the fiber cavity. Each clamping unit 200 includes a clamping base 210, and a moving unit 220 and a rotating unit 230 respectively mounted on the clamping base 210. The moving unit 220 is fixedly mounted on the clamping base 210 and has a fiber clamp for fixing the fiber. A rotating ring is mounted on the clamping base 210, and a rotating motor is fixedly mounted on the rotating ring. The rotating motor drives the rotating ring to rotate, and the rotation axis of the rotating ring coincides with the axis of the fiber cavity. A rotating fiber clamp is fixedly mounted on the rotating ring for clamping the fiber.

[0063] Adjacent clamping units 200 are symmetrically distributed with a plane perpendicular to the fiber cavity as the axis of symmetry. On adjacent clamping units 200, adjacent rotating rings are located between adjacent moving units 220.

[0064] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept.
