Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a yarn separation method for processing yarn bonding and a warp drawing-in machine. Background Art

[0002] As a new type of highly automated warp drawing-in equipment, automatic warp drawing-in machines offer significant advantages in speed and quality over traditional manual drawing-in. This significantly reduces drawing-in costs and improves both quality and efficiency, leading to their widespread adoption within the industry. However, with the continuous advancement of textile technology, the industry is placing higher demands on the applicability and quality of these machines.

[0003] Yarn sticking is an unavoidable problem during the warp drawing-in process. When the warp drawing-in machine draws yarn, there's a chance that multiple yarns will be drawn. Because of this sticking, the yarn identification device can't always accurately determine whether a single yarn is present, resulting in double warps and reduced drawing-in quality. Currently, the industry generally uses various types of brushes to brush the yarn curtain in an attempt to separate the yarns, or to increase the tension of the yarn to be drawn to reduce the probability of multiple yarns being drawn. However, these methods have not completely resolved the problem.

[0004] The existing technology has obvious deficiencies in the quality of yarn separation and cannot guarantee that the yarn can be accurately separated into single strands every time, which seriously affects the accuracy and efficiency of warp drawing. Summary of the Invention

An embodiment of the second aspect of the present invention provides a warp drawing-in machine, which adopts any of the above-mentioned yarn separation methods for processing yarn adhesion, and the warp drawing-in machine includes: A yarn taking structure, used for obtaining a target yarn, wherein the target yarn comprises one or more yarns; The line moving structure includes a yarn splitting member and a transfer member, or the line moving structure includes a yarn splitting member and a yarn splitting member moving device, the yarn splitting member is recessed with a limiting area suitable for accommodating only one yarn, the limiting area is suitable for obtaining the yarn obtained by the line taking structure, the transfer member is movably connected to the yarn splitting member, the transfer member is configured to have a first position and a second position, when the transfer member is switched from the first position to the second position, the transfer member is suitable for driving the yarn to move so that the limiting area only accommodates one yarn, and the yarn located in the limiting area is separated from other yarns; or the yarn splitting member is configured to have a first position and a second position, when the yarn splitting member is switched from the first position to the second position, the yarn in the limiting area is driven to separate from other yarns; The detection structure is used to detect the amount of yarn obtained by the yarn taking structure. The detection structure is configured to have a first state. In the first state, the transfer member is in the second position, or the yarn dividing member is in the second state.

[0011] In some embodiments, the detection structure is further configured to have a second state, in which the transfer element is in the first position.

[0012] In some embodiments, the yarn separating member includes a guide structure connected to the limiting area, and the transfer member is suitable for driving the yarn to move along the guide structure to the limiting area.

[0013] In some embodiments, the yarn separating member includes a yarn separating plate, the yarn separating plate is concavely provided with a first groove, and the first groove is configured as a limiting area; The yarn dividing plate has a first edge, the first edge is connected to the first groove, and the first edge is configured as a guide structure.

[0014] In some embodiments, the yarn separating member includes a yarn separating plate, the yarn separating plate includes a protruding hook, the hook and the edge of the yarn separating member form a second groove, and the second groove is configured as a limiting area; The yarn dividing plate has a second edge, the second edge is connected to the second groove, and the second edge is configured as a guide structure.

[0015] According to the above embodiments, the beneficial effects of the present invention are: The present invention provides a yarn separation method and a warp drawing-in machine for processing yarn adhesion. The yarn separation method for processing yarn adhesion includes: S101: Acquire target yarn, wherein the yarn includes one or more yarns; S103: making the target yarn enter the limiting area and making the target yarn move relative to the limiting area; S105: photographing a preset position of the target yarn to obtain information; S107: Determine whether the number of the target yarn is one according to the information.

[0016] Regarding "obtaining a target yarn, wherein the target yarn includes yarns," first, the method of the present invention obtains the target yarn through a thread-taking structure, wherein the target yarn includes one or more yarns. The thread-taking structure serves to fix a node of the yarn for subsequent operations. Regarding "limiting the yarn of the target yarn and driving the target yarn to move," specifically, one of the target yarns is limited by a yarn-splitting member and a transfer member in the thread-shifting structure. The yarn-splitting member is provided with a limiting area suitable for accommodating only one yarn, and the transfer member is movably connected to the yarn-splitting member. When the transfer member switches from a first position to a second position, it drives the yarn to move, separating the limited yarn from the other yarns. Excess yarn is moved out of the limiting area by the transfer member. Regarding "photographing the preset position of the target yarn to obtain first information," specifically, after the yarns are separated, the preset position of the target yarn is photographed again to obtain the first information. The first information is used to determine the number of yarns in the target yarn. Regarding "whether the number of yarns in the target yarn is one based on the first information", specifically, when obtaining the first information, the sticky yarns have been separated, so the first information obtained in this application is more accurate, and through the first information, it is more accurate to judge whether the number of yarns in the target yarn is one.

[0017] The yarn separation method for addressing yarn adhesion limits the position of one of the target yarns, separates the limited yarn from the other yarns under the action of a transfer member, and then detects and obtains the first information.

[0018] In addition, a second test can be added after obtaining the target yarn, that is, obtaining the second information. If the second information shows that there are two or more yarns in the harness, the judgment result is obtained directly, thereby eliminating the need for subsequent yarn separation operations, thereby improving efficiency.

[0027] Reference below Figures 1 to 8 The yarn separation method and the warp drawing-in machine for processing yarn bonding according to the embodiments of the present invention will be described.

[0028] Reference Figure 1In some embodiments, a yarn separation method for treating yarn bonding includes: S101: Obtain target yarn, wherein the yarn includes one or more yarns 410; S103: making the target yarn enter the limiting area and making the target yarn move relative to the limiting area; S105: photographing a preset position of the target yarn to obtain information; S107: Determine based on the information whether the number of the target yarn 410 is one.

[0029] Regarding "obtaining the target yarn, wherein the target yarn includes yarn 410", first, the method of the present invention obtains the target yarn through the thread-taking structure 100, and the target yarn includes one or more yarns 410. The function of the thread-taking structure 100 is to fix a node of the yarn 410 for subsequent operations. Regarding "limiting one of the target yarns 410 and driving the target yarn to move so that the limited yarn 410 is separated from the other yarns 410", specifically, one of the target yarns 410 is limited by the yarn dividing member 210 and the transfer member 220 in the thread-shifting structure 200. The yarn dividing member 210 is provided with a limiting area 213 that is only suitable for accommodating one yarn 410, and the transfer member 220 is movably connected to the yarn dividing member 210. When the transfer member 220 switches from the first position to the second position, the yarn 410 is driven to move so that the limited yarn 410 is separated from the other yarns 410. Excess yarn 410 is moved out of restricted area 213 by transfer member 220. Regarding "photographing the preset position of the target yarn to obtain first information," specifically, after yarn 410 is separated, the preset position of the target yarn is photographed again to obtain first information. This first information is used to further determine the number of yarns 410 in the target yarn. Regarding "determining whether the number of yarns 410 in the target yarn is one based on the first information," specifically, when obtaining the first information, the adhering yarns 410 have already been separated. Therefore, the first information obtained in this application is more accurate, and the determination of whether the number of yarns 410 in the target yarn is one is more accurate based on this first information.

[0030] Furthermore, after the step of obtaining the target yarn, wherein the target yarn includes the yarn 410, the method further includes: The preset position of the target yarn is photographed to obtain second information.

[0031] After obtaining the target yarn, a detection is also added to obtain the second information. If the second information shows that there are two or more yarns 410 in the harness, the judgment result is directly obtained, thereby eliminating the need for subsequent yarn separation operations, thereby improving efficiency.

[0032] Furthermore, in some embodiments, the step of photographing the preset position of the target yarn to obtain the second information includes: Determining whether the number of yarn 410 in the second information feedback is one; If the number of yarns 410 fed back by the second information is greater than one, the target yarn is retrieved again.

[0033] When it is initially determined that there are multiple yarns 410, they are re-acquired to improve efficiency; when it is initially determined that there is one yarn 410, further judgment is made later to ensure the detection quality.

[0034] Furthermore, in some embodiments, the step of photographing a preset position of the target yarn to obtain the first information includes: Determining whether the number of yarn 410 in the first information feedback is one; If the number of yarns 410 fed back by the first information is greater than one, the target yarn is retrieved again.

[0035] Through the above steps, the double judgment results are compared to ensure the accuracy of the detection.

[0036] Furthermore, in some embodiments, the yarn separation method for processing yarn bonding further includes: Determining whether the number of yarn 410 in the second information feedback is one; Determining whether the number of yarn 410 in the first information feedback is one; If the number of yarns 410 fed back by the second information and the first information is both one, it is determined that the number of yarns 410 of the target yarn is one. If the number of yarns 410 fed back by at least one of the second information or the first information is multiple, it is determined that the number of yarns 410 of the target yarn is multiple.

[0037] When implementing the yarn separation method for addressing yarn adhesion, the target yarn, comprising one or more yarns 410, is first obtained by the yarn extraction structure 100. The yarn extraction structure 100 secures a node of the yarn 410 for subsequent operations. Next, a predetermined position of the target yarn is photographed to obtain second information. This photographing step is performed while the target yarn is still intact, to provide a preliminary estimate of the number of yarns 410 in the target yarn. Next, one of the target yarns 410 is positioned, driving the target yarn to move, separating the restricted yarn 410 from the other yarns 410. The yarn separation member 210 and the transfer member 220 in the yarn transfer structure 200 are configured. The yarn separation member 210 is provided with a restricted area 213 suitable for accommodating only one yarn 410, and the transfer member 220 is movably connected to the yarn separation member 210. When the transfer member 220 switches from the first position to the second position, the yarn 410 is driven to move, separating the restricted yarn 410 from the other yarns 410. The excess yarn 410 is moved out of the limiting area 213 by the transfer member 220. After the yarn 410 is separated, the preset position of the target yarn is photographed again to obtain the first information. The first information is used to further determine the number of yarns 410 in the target yarn.

[0038] Next, the second information and the first information are judged separately: Determine whether the number of the yarn 410 fed back in the second information is one: If the second information shows that the number of the yarn 410 is one, it means that the target yarns in the unseparated state only include one yarn 410.

[0039] Determine whether the number of the yarn 410 fed back in the first information is one: If the first information shows that the number of the yarn 410 is one, it means that the target yarns in the separated state only include one yarn 410.

[0040] Combining the two determination results: If both the second information and the first information indicate that the number of yarns 410 is one, it is determined that the target yarn contains only one yarn 410. If at least one of the second information or the first information indicates that the number of yarns 410 is multiple, it is determined that the target yarn contains multiple yarns 410 and the target yarn needs to be retrieved again.

[0041] Through the above steps, the yarn separation method for treating yarn adhesion of the present invention can effectively ensure that the target yarn contains only one yarn 410, thereby improving the yarn separation quality of the warp drawing machine. This method combines information from both the unseparated and separated states through two-step imaging and judgment, ensuring the accuracy and reliability of the detection.

[0042] Reference Figures 2 to 8, an embodiment of the second aspect of the present invention proposes a warp drawing machine, which adopts the yarn separation method for processing yarn bonding according to any of the above embodiments. The warp drawing machine of the present invention includes a thread taking structure 100, a thread moving structure 200 and a detection structure 300. The thread taking structure 100 is used to obtain the yarn 410, and the thread moving structure 200 includes a yarn separation component 210 and a transfer component 220. The yarn separation component 210 is provided with a limiting area 213 suitable for accommodating only one yarn 410, and the limiting area 213 is suitable for obtaining the yarn 410 obtained by the thread taking structure 100. It can be understood that the thread taking structure 100 fixes one node of the yarn 410, and the limiting area 213 fixes another node of the yarn 410. The transfer component 220 is movably connected to the yarn separation component 210, referring to Figure 4 and Figure 5 The transfer member 220 is configured to be a first position and a second position. When the transfer member 220 switches from the first position to the second position, the transfer member 220 can drive the yarn 410 to move. Since the limiting area 213 can only accommodate one yarn 410, the excess yarn 410 will be moved out of the limiting area 213 by the transfer member 220.

[0043] Reference Figures 2 to 4 The detection structure 300 is used to monitor the number of yarns 410 connected to the line-taking structure 100. The detection structure 300 is configured to have a second state and a first state. Figure 4 and Figure 5 In the second state, the transfer member 220 is in the first position, that is, the transfer member 220 has not yet driven the yarn 410 to move, and the yarn 410 obtained by the thread-taking structure 100 has not yet been associated with the receiving groove; in the first state, the transfer member 220 is in the second position, that is, the transfer member 220 has driven the yarn 410 to move, and there is only one yarn 410 in the receiving groove at this time. If there is extra yarn 410, it will be separated from the yarn 410 positioned in the receiving groove under the drive of the transfer member 220. This separation situation is easier for the detection structure 300 to judge.

[0044] It can be seen that the detection structure 300 of the present application obtains two judgment results in the second state and the first state, and combines the two to determine whether the line-taking structure 100 has only obtained a single yarn 410. Specifically, in the second state, the line-taking structure 100 obtains the yarn 410. At this time, if the yarns 410 block each other, it is easy to mistakenly conclude that the line-taking structure 100 has actually only obtained one yarn 410. The yarn 410 obtained by the line-taking structure 100 is separated by the line-moving structure 200, thereby avoiding the influence of blockage, etc., and the separated yarn 410 is easier to detect. In other words, the first state further ensures the accuracy of the detection structure 300. Of course, in the second state, that is, when it is detected that the line-taking structure 100 has not obtained a yarn 410, the line-taking structure 100 can obtain the yarn 410 again.

[0045] In summary, by combining the two states of detection, the accuracy of each detection is ensured, which greatly improves the yarn separation quality of the warp drawing machine. Moreover, the detection of the second state can quickly determine that the yarn taking structure 100 has not obtained a yarn 410. This application not only has accurate detection, but also high efficiency.

[0046] In some embodiments, the yarn retrieval structure 100 utilizes a vacuum suction principle, using a suction head with suction holes to grasp the yarn 410. A vacuum pump is internally connected to the suction head, which uses negative pressure to absorb the yarn 410. The suction force can be adjusted based on the material and diameter of the yarn 410. The suction head surface is designed with a flexible material to avoid damage to the yarn 410. A fiber optic sensor is also integrated within the suction head to detect whether the yarn 410 is properly absorbed, ensuring the reliability of the yarn retrieval process.

[0047] In some embodiments, the yarn-taking structure 100 is designed as a mechanical clamping device that grasps the yarn 410 through a pair of resilient jaws that can be opened and closed. The jaws are made of a flexible material (such as rubber or silicone) to reduce damage to the yarn 410, and the opening and closing action is achieved by pneumatic or electric drive.

[0048] In some embodiments, the yarn-grabbing mechanism 100 is designed as a multi-point contact device, simultaneously grasping the yarn 410 through multiple small grippers or suction points. This multi-point contact design disperses the gripping force, reducing damage to the yarn 410 while improving grip stability. The force and position of each contact point can be independently adjusted to ensure uniform gripping of the yarn 410. Furthermore, the contact points are surface-coated with antistatic material to prevent entanglement or adhesion of the yarn 410 due to static electricity.

[0049] Regarding the detection structure 300, it is understood that in some embodiments, the detection mechanism is a visual system that detects the number of yarns 410 through camera imaging and a specific program. Visual system detection methods are well-established in the art and will not be discussed in detail here. This application focuses on reducing detection errors through the rational design of the mechanism, rather than the design of the internal software and hardware of the detection structure 300.

[0050] It is understandable that in some embodiments, in order to further enhance the flexibility of the warp drawing machine, the thread taking structure 100 can be made of a flexible material, which not only improves the compatibility with yarns 410 of different materials, but also reduces damage to the yarns 410. For example, the thread taking structure 100 can be made of a soft and elastic synthetic fiber, which can provide sufficient friction to stably grasp the yarn 410 and can easily release the yarn 410 when not needed. In addition, the design of the transfer member 220 can also be improved, such as changing the movement mode of the transfer member 220 from a simple rotation to a complex trajectory including a certain angle of deflection, so that the movement path of the yarn 410 can be more accurately controlled to ensure that each yarn 410 can smoothly enter the limiting area 213.

[0051] It is understandable that the transfer member 220 is movably connected to the yarn splitting member 210 only for the purpose of separating the excess yarn 410 in the target yarn from the yarn 410 located in the limited area through the operation of the transfer member 220. Therefore, the connection form of the transfer member 220 and the yarn splitting member 210 is not limited, and can be rotation or translation, etc., and the relative position of the transfer member 220 and the yarn splitting member 210 is not limited. The transfer member 220 can be arranged above the yarn splitting member 210 or below the yarn splitting member 210, and it only needs to drive the yarn 410 to move to separate the excess yarn 410 in the wire harness. In addition, the connection and unloading structure of the transfer member 220 is also not limited, and can be in various forms such as a push rod and a suction head. The design of the transfer member 220 that meets the purpose of this application is within the protection scope of this application.

[0052] It will be appreciated that in some embodiments, the drawing-in machine may also incorporate intelligent sensing technology, enabling the detection structure 300 to not only identify the number of yarns 410 but also analyze the condition of the yarns 410 (e.g., breakage or entanglement). For example, by installing a small optical sensor near the yarn take-up structure 100, the flow of the yarns 410 can be directly monitored and real-time feedback provided to the control system. Upon detecting an abnormal condition, the system immediately responds, such as stopping the yarn supply or adjusting the position of the transfer element 220. This design not only increases the degree of automation of the entire yarn separation process but also significantly reduces the risk of production interruptions due to problems with the yarns 410.

[0053] Reference Figures 6 to 8In some embodiments, the yarn splitting member 210 includes a guide structure 212, and the guide structure 212 is connected to the limiting area 213, so that the transfer member 220 can drive the yarn 410 to move along the guide structure 212 to the limiting area 213. The design of the guide structure 212 takes into account the physical properties of the yarn 410 and the requirements of the moving path. It is usually a smooth groove or channel, which can not only guide the yarn 410 to transition smoothly, but also prevent the yarn 410 from getting stuck or entangled during the movement. In this way, the yarn 410 can be smoothly transferred from the line taking structure 100 to the limiting area 213, ensuring the smoothness and efficiency of the entire yarn splitting process. In addition, the provision of the guide structure 212 also enhances the reliability of the warp drawing machine because it reduces the possibility of the yarn 410 deviating from the predetermined path during the transfer process.

[0054] It will be appreciated that, in some embodiments, the guide structure 212 can be designed to be adjustable, allowing the user to adjust its width or shape according to actual needs. For example, the guide structure 212 can be designed to be composed of two relatively movable metal sheets, and the distance between the two metal sheets can be adjusted according to the diameter of the yarn 410 being used. In this way, whether processing thicker or thinner yarns 410, the yarn 410 can be ensured to move smoothly along the guide structure 212, and operation failures due to being too tight or too loose can be avoided. In addition, the surface of the guide structure 212 can also be covered with a low-friction coating to further reduce the resistance of the yarn 410 during movement, ensuring smooth operation.

[0055] It will be appreciated that in some embodiments, the guide structure 212 may also incorporate magnetic materials or electromagnetic fields to assist in the directional movement of the yarn 410. For example, a set of tiny magnets or electromagnetic coils may be mounted at the bottom of the guide structure 212, leveraging the magnetic field to guide the magnetic yarn 410 along a predetermined path. This approach is particularly suitable for specialized yarns 410 containing metal components or other magnetizable materials. This approach not only enables more precise guidance of the yarn 410 but also enhances the system's intelligence, enabling it to automatically adjust the optimal guidance scheme for each type of yarn 410.

[0056] Reference Figure 7In some embodiments, the yarn splitter 210 includes a yarn splitter plate 211 with a first recessed groove 2111, which serves as a retaining area 213 and is designed to accommodate only a single yarn 410. Due to the strict size of the first recessed groove 2111, only a single yarn 410 can enter and remain within it. If multiple yarns 410 attempt to enter simultaneously, the additional yarns 410 are blocked from passing through the narrow entrance of the first recessed groove 2111. Furthermore, the yarn splitter plate 211 has a first edge that connects to the first recessed groove 2111 and is configured as a guide structure 212. When the yarn 410 is transferred from the thread take-up structure 100, it first contacts the guide structure 212 and then smoothly moves along the guide structure 212 to the first recessed groove 2111. This structure not only facilitates a smooth transition of the yarn 410 but also prevents jamming or tangling during movement, thereby improving the efficiency and accuracy of the entire yarn splitting process.

[0057] It will be appreciated that in some embodiments, the width of the first groove 2111 can be designed to be adjustable to accommodate yarns 410 of varying thicknesses. For example, a fine-tuning device can be installed to allow the user to adjust the opening size of the first groove 2111 according to actual needs. This ensures that both thicker and thinner yarns 410 are properly inserted into the first groove 2111 without clogging or leakage. Furthermore, the first edge of the guide structure 212 can also be interchangeable, providing edge modules with varying angles and curvatures to meet the needs of various application scenarios.

[0058] Reference Figure 8 In some embodiments, the yarn splitter 210 includes a yarn splitter plate 211 with a protruding barbed hook. The barbed hook and the edge of the yarn splitter plate 211 together form a second groove 2112, which serves as a positioning area 213. The second groove 2112 is designed to accommodate only one yarn 410. The yarn splitter plate 211 has a second edge that connects to the second groove 2112 and is configured as a guide structure 212. In this design, the yarn 410 is first guided by the guide structure 212 (second edge) and then moves along a path to the second groove 2112. The barbed hook design increases the complexity of the structure, but also provides better positioning of the yarn 410, ensuring that each yarn 410 accurately enters the predetermined position. Specifically, the presence of the barbed hook narrows the entrance to the second groove 2112, effectively preventing multiple yarns 410 from entering simultaneously.

[0059] It is understood that in some embodiments, the design of the barb can be optimized to provide a certain degree of elasticity. For example, the barb can be made of a highly elastic metal material. This allows the barb to securely hold the yarn 410 when necessary, while also allowing it to bend appropriately when subjected to significant external forces, thus preventing damage to the yarn 410. Furthermore, the bottom of the second groove 2112 can be designed to be slightly inclined to facilitate the natural sliding of the yarn 410 to the deepest position, thereby reducing the occurrence of jamming.

[0060] Reference Figure 5 and Figure 6 In some embodiments, the transfer member 220 is rotatably connected to the yarn splitting member 210. Specifically, the transfer member 220 is connected to the yarn splitting member 210 via a rotating axis, so that the transfer member 220 can rotate relative to the yarn splitting member 210 around this axis. This design allows the transfer member 220 to switch between a first position and a second position. When the transfer member 220 is in the first position, it does not directly interact with the yarn 410, and at this time, the yarn 410 has no direct contact with the limiting area 213. When it is necessary to adjust the position of the yarn 410 or to ensure that there is only one yarn 410 in the limiting area 213, the transfer member 220 will rotate from the first position to the second position. During this process, the transfer member 220 will contact and push the yarn 410, causing it to move along the guide structure 212 until only one yarn 410 remains in the limiting area 213.

[0061] It will be appreciated that in some embodiments, a damping device or spring mechanism may be positioned near the rotation axis to increase the flexibility of the transfer member 220. For example, a small hydraulic damper may be used to adjust the rotational speed of the transfer member 220. This allows its movement rate to be adjusted according to actual needs, preventing damage to the yarn 410 caused by excessively rapid operation. Furthermore, the spring mechanism can provide additional elastic force, helping the transfer member 220 better adapt to yarns 410 of varying thicknesses and ensuring that it remains firmly in contact with the surface of the yarn 410, thereby improving separation accuracy.

[0062] Reference Figure 5 and Figure 6In some embodiments, the transfer member 220 includes a disc body 221 and a hook 222. The disc body 221 serves as the primary support component, possessing a certain degree of rigidity and strength to withstand various stresses during operation. The hook 222 is fixed to one side of the disc body 221, with its end spaced apart from the disc body 221, forming a third receiving groove extending circumferentially around the disc body 221. This structural design enables the third receiving groove to effectively capture and store all yarns 410 retrieved from the thread-taking structure 100. When the transfer member 220 is in the first position, the third receiving groove is separated from the yarns 410, undisturbed. When the transfer member 220 is rotated to the second position, the third receiving groove precisely encloses all yarns 410. Due to the influence of the limiting area 213, the thread-taking structure 100 serving as a positioning point, and the third groove 223 serving as a positioning point, the yarns 410 split at the yarn-dividing member 210, facilitating detection by the detection structure 300.

[0063] Further, refer to Figure 5 and Figure 6 In some embodiments, when the transfer member 220 is in the first position, the third receiving groove is separated from the yarn 410. At this time, the yarn 410 is not affected by the thread-taking structure 100, the limiting area 213, and the third groove 223, and the yarn 410 is not forcibly bifurcated due to external forces. When the transfer member 220 rotates to the second position, the third receiving groove can accommodate all the yarns 410 obtained by the thread-taking structure 100. One node of the yarn 410 is fixed by the thread-taking structure 100, and one node is fixed by the third groove 223. The two nodes are restricted by the limiting area 213. Under the drive of the transfer member 220, the yarn 410 originally adhered to the yarn 410 trapped in the limiting area 213 will bifurcate with the yarn 410 that later trapped in the limiting area 213, thereby facilitating the detection of the inspection structure.

[0064] In some embodiments, the drawing-in machine can also incorporate an automatic correction function. For example, if the detection mechanism 300 detects an anomaly (e.g., the number of yarns 410 does not match the expected number), the system automatically triggers a correction mechanism, readjusting the position of the transfer element 220 until the problem is resolved. This not only improves the system's fault tolerance but also reduces manual intervention, further enhancing production efficiency.

[0065] It is understood that in some embodiments, the drawing-in machine can be equipped with an intelligent control system to monitor and optimize its operating status in real time. For example, a sensor network can be installed to collect data on the movement of the yarn 410 and the position of the transfer element 220, and data analysis techniques can be used to predict potential failure points. Based on this information, the system can take preventive measures in advance to avoid downtime or reduce maintenance costs. This intelligent design not only improves equipment performance but also enhances the user experience.

[0066] Below, reference Figures 1 to 8 , the system exemplifies the yarn separation method and the warp drawing machine for processing yarn adhesion of the present invention. The warp drawing machine of the present invention includes a thread taking structure 100, a thread moving structure 200 and a detection structure 300. The thread taking structure 100 is used to obtain the yarn 410 in the thread curtain. Specifically, a plurality of yarns 410 are fixed by an upper clamping strip 420 and a lower clamping strip 430 to form a thread curtain. The thread taking structure 100 can be a suction nozzle, and the suction nozzle is provided with a U-shaped opening for accommodating the yarn 410. The thread taking structure 100 takes out the frontmost yarn 410 in the thread curtain and then transfers it to the position of the thread moving structure 200. At this time, the yarn 410 is about to come into contact with the thread moving structure 200, but the limiting area 213 cannot affect the state of the yarn 410 in the thread taking structure 100. Before the yarn 410 and the thread moving mechanism 200 occur, the detection mechanism 300 first detects the yarn 410 of the thread taking mechanism 100 to determine whether it is a single yarn 410. If it is a single yarn 410, the subsequent action is performed. If it is multiple yarns 410, the thread taking mechanism 100 abandons this group of yarns 410 and takes a new thread. The second state is a preliminary judgment. The preliminary judgment method can improve efficiency and promptly discard the situation where the number of yarns 410 does not meet the requirements.

[0067] Regarding the detection structure 300, the detection structure 300 can be a visual system equipped with a camera, so when detecting the number of yarns 410, it is necessary to ensure that all detected yarns 410 are within the visual range of the camera.

[0068] After the yarn taking structure 100 establishes a relationship between the yarn 410 and the line structure, the yarn 410 will be bifurcated under the influence of the limiting area 213 of the yarn splitting member 210 under the drive of the transfer member 220. Specifically, the yarn splitting member 210 can be a yarn splitting plate 211, which has a groove, which can be a first groove 2111 that is self-concave, or a second groove 2112 with an inverted hook design. The groove is configured as a limiting area 213, and the limiting area 213 can only accommodate one yarn 410. The transfer member 220 includes a disc body 221 and a hook 222. A third groove 223 is formed between the hook 222 and the disc body 221, and the third groove 223 is used to accommodate the yarn 410. When the disc body 221 rotates, the yarn 410 will enter the limiting area 213 along the edge of the yarn splitting plate 211. The edge of the yarn splitting plate 211 is configured as a guide structure 212. Although the restricted area 213 can only accommodate one yarn 410, due to the adhesion of the yarns 410, the remaining yarns 410 will be adsorbed on the yarn 410 located in the restricted area 213. At this time, the transfer member 220 continues to push the yarn 410 to move. The yarn 410 located in the restricted area 213 is affected by the groove edge or the hook and cannot move out of the restricted area 213 along the driving direction of the transfer member 220. The other yarns 410 will continue to be pushed by the transfer member 220, thereby separating from the yarn 410 contained in the restricted area 213. It can be understood that at this time, the thread-taking structure 100 serves as a fixed point for the yarn 410, the third groove 223 serves as a fixed point for the yarn 410, and the transfer member 220 continuously drives the yarn 410 to move. The edge of the restricted area 213 restricts the movement of one of the yarns 410. Therefore, if there are multiple yarns 410, the multiple yarns 410 will fork at the restricted area 213. The bifurcation situation can avoid erroneous detection due to factors such as obstruction by the yarn 410, thereby improving the detection quality.

[0069] In summary, if the detection structure 300 detects a single yarn 410 in both the second state and the first state, it is determined that the thread-retrieving structure 100 has only retrieved a single yarn 410. If multiple yarns are detected in either state, it is determined that the thread-retrieving structure 100 has retrieved more than one yarn 410. Therefore, the detection quality of this application is better and the efficiency is high.
