Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent yarn sorting technology, specifically to an intelligent sorting system for wool yarn. Background Technology
[0002] As an important branch of the textile industry, the wool textile industry directly affects the quality and efficiency of downstream knitting, weaving and garment manufacturing. As the final packaged form in the wool textile process, the appearance quality and packaged forming quality of yarn are one of the core quality indicators. Traditional yarn sorting mainly relies on manual labor. Sorting workers judge and classify yarn based on visual observation and touch, such as color difference, shape and defects. This mode has prominent problems such as strong subjectivity of sorting standards, low efficiency, high labor intensity and susceptibility to fatigue leading to misjudgment and omission. With the development of intelligent manufacturing technology, automated sorting equipment using machine vision and sensor technology has emerged in the industry. However, in practical applications, some yarn packages may develop a "protruding edge" condition due to issues with the winding process. As the package diameter continues to increase, the contact pressure between the bobbin and the grooved drum increases accordingly, causing the yarn winding density to gradually increase from the inside out. This uneven winding structure causes the inner layer yarn to continuously bear radial compressive stress from the outer layer yarn. When the internal stress accumulates to exceed the stability critical value between the yarn layers, the relatively weak edge of the bobbin end becomes the breakthrough point for stress release. The inner layer yarn is squeezed outward and bulges, thus deviating from the ideal cylindrical envelope and forming a local or ring-shaped protruding edge defect. This defect is not a simple surface flaw; its harm is multi-layered and severe. For example, during subsequent high-speed unwinding, the protruding part is very likely to rub violently against the yarn guide and tension device, causing yarn fuzzing, strength loss, and even frequent breakage, seriously affecting weaving efficiency and fabric quality. During subsequent conveying and unwinding, the protruding edge yarn is very likely to cause yarn fuzzing, breakage, or even equipment jamming, seriously affecting the continuity of downstream processes and fabric quality. Therefore, we propose an intelligent sorting system for wool yarn packages. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves automated conveying and detection of yarn packages through a convex edge detection unit, a lifting frame, a clamping part, and a servo motor-driven lead screw body. Compared with the traditional manual sorting mode, this system significantly reduces the reliance on manual labor, reduces misjudgments and omissions caused by human fatigue or subjective judgment, greatly improves sorting efficiency and accuracy, and ensures the stability and consistency of yarn package product quality. In addition, the automated sorting process reduces the risk of contamination that may be caused by manual operation, further ensuring the purity and quality of the yarn packages. 2. This invention, through the coordinated operation of the detection roller, trigger rod, and sensing element, can accurately identify convex edge defects on the end face of the yarn package. This detection method is not sensitive to yarn color or reflective properties, ensuring the stability and reliability of the detection results under different lighting conditions and yarn colors. Once a convex edge defect is detected, the system immediately generates an electrical signal, providing an accurate basis for subsequent sorting and processing. Precise convex edge detection effectively avoids problems such as yarn fuzzing, strength loss, and even frequent breakage that may occur during the subsequent high-speed unwinding process of convex edge yarn packages. 3. This invention achieves non-destructive gripping of the inner wall of the yarn package through the ingenious design of the rotating sleeve, N-level magnet, and S-level magnet in the working unit. The principle of magnetic attraction or repulsion allows the clamping part to open or close radially simultaneously, which is both stable and does not damage the yarn package. In addition, through the combined action of hot air softening and hydraulic pressure, the convex edge of the yarn package is flexibly repaired. During the repair process, the rubber pad design of the bottom circular panel and the top circular panel effectively prevents yarn damage and ensures the quality of the repaired yarn package.

[0017] 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.
[0018] Please see Figure 1-14 This invention provides a technical solution: an intelligent sorting system for wool yarn packages. This intelligent yarn sorting system can automatically detect convex edge defects in yarn packages and automatically sort and process qualified and defective products based on the detection results. It effectively solves the problems of low efficiency, inconsistent standards, and the inability to automatically repair defective yarn packages in manual sorting. Combined with the attached... Figure 1 and attached Figure 2As shown, the system includes a first conveying mechanism 1 for conveying normal bobbins 3 and a second conveying mechanism 2 for conveying bobbins 3 with raised edges. The first conveying mechanism 1 and the second conveying mechanism 2 are connected. Multiple detection frames 4 are fixedly installed on the first conveying mechanism 1. The multiple detection frames 4 are installed sequentially along the conveying direction of the first conveying mechanism 1. A servo motor 41 is fixedly installed on the outer wall of one of the detection frames 4. The output end of the servo motor 41 is connected to a horizontal lead screw body 42. That is, the forward and reverse rotation of the servo motor 41 controls the forward and reverse rotation of the lead screw body 42. The lead screw body 42 passes through all the detection frames 4 and is rotatably connected to them through bearings (not shown in the figure). Inside each detection frame 4, a movable slider 43 is provided. The center of the movable slider 43 has an internal thread, which allows it to be threaded onto the lead screw body 42. At the same time, its side is slidably connected to the inner wall of the detection frame 4. When the servo motor 41 drives the lead screw body 42 to rotate, all the movable sliders 43 can move horizontally synchronously and precisely along the lead screw, that is, the forward and reverse rotation of the lead screw body 42 controls the movement direction of the movable sliders 43. Each movable slider 43 has a vertically sliding lifting frame 44 connected to its side wall. A vertical reciprocating screw 45 is rotatably mounted inside the lifting frame 44. A sliding sleeve 46 is threaded onto the reciprocating screw 45. A guide shaft 461 is fixed to the inner wall of the sliding sleeve 46. The guide shaft 461 cooperates with the sliding groove on the inner wall of the reciprocating screw 45, so that the sliding sleeve 46 can move up and down along the axial direction of the reciprocating screw 45 without rotating itself. An extension shaft 47 is fixed to the bottom of the sliding sleeve 46. A horizontal annular disc 48 is installed at the end of the extension shaft 47. Multiple clamping parts 49 are slidably connected to the annular disc 48. The end of the clamping part 49 that contacts the inner wall of the yarn package 3 is provided with a rubber pad for contacting and fixing the inner wall of the yarn package 3.
[0019] An action unit 5 is provided on the outer wall of the sliding sleeve 46. The action unit 5 is used to control the clamping part 49 to fix the inner wall of the yarn package 3. The action unit 5 includes a rotating sleeve 51, which is rotatably sleeved on the outer wall of the sliding sleeve 46 through a bearing (not shown in the figure). One end of the rotating sleeve 51 extends into the annular disc frame 48, and multiple N-level magnets 52 and S-level magnets 53 are alternately fixedly installed at the end. Furthermore, the clamping part 49 is made of magnetic material and the magnetic pole is N-level. When the rotating sleeve 51 rotates and changes the relative magnetic pole position of the magnet and the clamping part 49, the principle of magnetic attraction or repulsion can be used to drive all clamping parts 49 to open or close radially without contact, thereby clamping or releasing the yarn package 3.
[0020] At the bottom of the lifting frame 44, a meshing gear 441 is rotatably installed. Correspondingly, two rack bodies 401 are fixedly installed on the inner wall of the detection frame 4. When the lifting frame 44 moves forward with the movable slider 43, the meshing gear 441 can mesh with the rack body 401. Here, "forward" means the same as the movement direction of the first conveying mechanism 1. It should be noted that the movement speed of the movable slider 43 is the same as the movement speed of the yarn package 3. At the same time, a gear body 451 is fixed at the top of the reciprocating screw 45, and four tooth rows 40 arranged along the movement path are fixed on the inner wall of the detection frame 4. Through the movement of the movable slider 43, the gear body 451 will mesh with different tooth rows 40 in sequence, thereby driving the reciprocating screw 45 to intermittently rotate forward and backward, and finally precisely controlling the sliding sleeve 46 and the clamping part 49 to perform the sequential action of "descending-grabbing-lifting-descending-releasing". To automatically reset after completing the inspection of a workstation, telescopic shafts 442 are fixed on both sides of the lifting frame 44. A special limiting groove 402 is provided on the inner wall of the inspection frame 4 for sliding. The limiting groove 402 consists of a straight area 403, an upward tilting area 404, a return area 405, and a downward tilting area 406. At the connection between the straight area 403 and the upward tilting area 404, a guide panel 407 is provided with one side being an inclined surface and the other side being a right-angled surface. When the telescopic shaft 442 passes the guide panel 407 of the straight area 403, the telescopic shaft 442 will cross the inclined surface and continue to move. However, when moving in the opposite direction, the right-angled surface of the guide panel 407 will guide the telescopic shaft 442 to enter the upward tilting area 404.
[0021] A convex edge detection unit 6 is provided on the side wall of the detection frame 4. The convex edge detection unit 6 includes a positioning sleeve 61 and a detection roller 62 rotatably connected to it via a bearing (not shown in the figure). A torsion spring 65 (preferably a small torque torsion spring 65) is connected between the detection roller 62 and the positioning sleeve 61 to enable it to automatically reset. A trigger rod frame 63 is fixed on the detection roller 62, and a sensing element 64 is installed on the positioning sleeve 61. The sensing element 64 is located on the rotation trajectory of the trigger rod frame 63. When there is a convex edge on the end face of the lifted yarn 3, the convex part will squeeze the detection roller 62, causing it to rotate against the force of the torsion spring 65, thereby driving the trigger rod frame 63 to swing and trigger the sensing element 64. The system determines that there is a convex edge defect in the yarn 3. This contact physical detection method is not sensitive to yarn color and reflective properties, and the detection results are stable and reliable.
[0022] A sorting and pushing unit 7 is provided at the connection between the first conveying mechanism 1 and the second conveying mechanism 2. The sorting and pushing unit 7 conveys the yarn package 3 with protruding edges to the second conveying mechanism 2. The sorting and pushing unit 7 can be a cylinder or an electric push rod. When it receives a protruding edge signal, it will move to push the defective yarn package 3 laterally away from the first conveying mechanism 1, so that it enters the second conveying mechanism 2 or the subsequent processing area, thereby realizing automatic sorting.
[0023] Between the first conveying mechanism 1 and the second conveying mechanism 2, a yarn package repair mechanism 8 is also provided. The yarn package repair mechanism 8 mainly includes a fixed frame 81, a hydraulic cylinder 82, a bottom circular panel 83 driven to rise and fall by the hydraulic cylinder 82, and a top circular panel 84 fixed to the frame. Both the bottom circular panel 83 and the top circular panel 84 have internal hot air channels 85, allowing hot air to be introduced to soften the end face of the yarn package 3. The bottom circular panel 83 has a centrally located annular panel 87 connected by a spring mechanism 86, giving it a certain degree of elasticity and flexibility. Rubber pads are also laid on the surfaces of the bottom circular panel 83 and the top circular panel 84 to prevent over-repair. During the process, the yarn is damaged, and the top circular panel 84 has a circular hole at the top for inserting the end of the yarn package 3. When conveying the convex edge yarn package 3, one end of the bottom of the yarn package 3 will move to the annular panel 87. At this time, the annular panel 87 is flush with the bottom circular panel 83. When repair is needed, hot air is first circulated, and then the hydraulic cylinder 82 is controlled to process it. That is, the hydraulic cylinder 82 controls the bottom circular panel 83 to move upward, and the annular panel 87 moves synchronously with it until the top of the yarn package 3 contacts the surface of the top circular panel 84. Then the hydraulic cylinder 82 continues to rise, and the pressure during the rise can be controlled so that the softened convex edge is repaired under the action of pressure.
[0024] Working principle: The yarn package 3 to be inspected is conveyed forward by the first conveying mechanism 1 in a step-by-step manner. When the yarn package 3 reaches a detection station, the system automatically works according to the following coordinated and orderly process: The servo motor 41 starts, driving the lead screw body 42 to rotate at a uniform speed. Since all the movable sliders 43 are threaded onto the lead screw body 42, they begin to move horizontally along the inner wall of the detection frame 4 synchronously. At this time, the movement speed of the movable sliders 43 is the same as the movement speed of the yarn package 3. Each movable slider 43 drives the lifting frame 44 on its side to move forward together. Initially, the telescopic shafts 442 on both sides of the lifting frame 44 are located in the straight-line area 403 of the limiting groove 402, so that the lifting frame 44 keeps The horizontal movement continues; when the lifting frame 44 moves to the working starting point, the gear body 451 fixed at the top of the reciprocating screw 45 engages with the first tooth row 40 on the inner wall of the detection frame 4. This engagement forces the reciprocating screw 45 to start rotating. Through the cooperation between the guide shaft 461 on the inner wall of the sliding sleeve 46 and the inner groove of the reciprocating screw 45, the rotational motion is converted into the linear downward motion of the sliding sleeve 46. The sliding sleeve 46 drives the annular disc frame 48 and the clamping part 49 in the retracted state to descend as a whole through the extension shaft 47, and smoothly inserts into the inner hole of the paper tube of the yarn package 3. At this time, the clamping part 49 will not contact the inner wall of the inner hole of the paper tube of the yarn package 3 during the descent, that is, it smoothly enters its interior. Immediately afterwards, the gear body 451 disengages from the first tooth row 40 and enters a gap area of a toothless row 40. At the same time, the meshing gear 441 at the bottom of the lifting frame 44 moves to the position where it meshes with the rack body 401 on the inner wall of the detection frame 4. The rotation of the meshing gear 441 causes the rotating sleeve 51 to rotate on the outer wall of the sliding sleeve 46. The N-pole magnets and S-pole magnets arranged alternately at the end of the rotating sleeve 51 rotate accordingly, so that the N-pole magnets are aligned with the clamping part 49 made of N-pole magnetic material to generate a repulsive force, driving all the clamping parts 49 to slide outward radially synchronously on the annular disc frame 48 until the rubber pads at their ends firmly support the inner wall of the yarn 3, completing the non-destructive gripping.
[0025] After the gripping action is completed, the gear body 451 engages with the second gear row 40. This engagement drives the reciprocating screw 45 to rotate, thereby causing the sliding sleeve 46, the extension shaft 47, and the firmly gripped yarn 3 to rise smoothly. This allows the yarn 3 to completely detach from the bearing surface of the first conveying mechanism 1 and be in a suspended detection state. After the yarn 3 is lifted, its upper and lower end faces are aligned with the detection roller 62 set on the side wall of the detection frame 4. If the end face of the yarn 3 is flat, the detection roller 62 remains stationary, and the trigger rod 63 will not trigger the sensing element 64. If the yarn 3 has a convex edge defect, the protruding yarn part will squeeze the detection roller 62, causing it to rotate against the torque of the torsion spring 65. The rotation drives the trigger rod 63 fixed on it to swing. When the rod swings past the sensing element 64, it is detected by the sensing element 64, thereby generating a clear electrical signal of the convex edge defect. After the inspection is completed, regardless of whether the yarn package 3 is qualified, it needs to be returned. The servo motor 41 drives the lead screw body 42 to continue rotating, and the movable slider 43 continues to move forward. At this time, the gear body 451 moves to mesh with the third gear row 40. This meshing again drives the reciprocating lead screw 45 to rotate, causing the sliding sleeve 46 and the clamped yarn package 3 to descend smoothly until the bottom of the yarn package 3 contacts the bearing surface of the first conveying mechanism 1. Subsequently, the gear body 451 disengages from the third gear row 40 and enters the next gap area. In this gap area, the meshing gear 441 at the bottom of the lifting frame 44 moves to mesh with the second rack body 401. The renewed rotation of gear 441 drives the rotating sleeve 51 to rotate, causing the S-pole magnet to align with the clamping part 49 made of N-pole magnetic material. This drives all clamping parts 49 to slide radially inward simultaneously, disengaging from the inner wall of the yarn package 3, thus safely releasing the yarn package 3. After release, the clamping parts 49 return to their retracted state. After releasing the yarn package 3, gear body 451 continues to advance and meshes with the fourth gear row 40. This final meshing drives the reciprocating screw 45 to rotate, lifting the sliding sleeve 46, extension shaft 47, and clamping parts 49, which were already in the retracted state, so that they are fully retracted and returned to their original positions, avoiding interference with the subsequent conveying of the yarn package 3. When the telescopic shafts 442 on both sides of the lifting frame 44 move to the end of the straight-line area 403 near the limiting groove 402, the gear body 451 and the fourth gear row 40 are engaged. The telescopic shafts 442 will then pass over the inclined surface of the guide panel 407. After the detection is complete, the servo motor 41 reverses, and under the action of the lead screw body 42, the movable slider 43 drives the lifting frame 44 to move in the same direction. The telescopic shafts 442 will then move along the guide panel 407. Guided by the corner surface, it enters the inclined upward region 404, thereby driving the entire lifting frame 44 to rise. Subsequently, the telescopic shaft 442 passes through the return region 405 and the inclined downward region 406 in sequence. During this process, neither the gear body 451 nor the meshing gear 441 meshes with any gear row 40 or rack. The mechanism is unloaded and efficiently resets. Finally, the telescopic shaft 442 slides back to the starting end of the straight travel region 403, and the lifting frame 44 also descends to the initial height, preparing for the next work cycle. Upon receiving the convex edge detection signal, the central controller (existing technology, not described in detail) immediately makes a decision; if no convex edge signal is detected, it is judged as a qualified product, and the subsequent mechanism executes the action of lowering and releasing the yarn package 3, which falls back to the first conveyor mechanism 1 and continues to flow to the next process; if a convex edge signal is detected, it is judged as a defective product; when the yarn package 3 moves with the conveyor mechanism to the connection point with the second conveyor mechanism 2, the sorting and pushing part 7, like a cylinder, immediately actuates, and its piston rod quickly extends to push the convex edge yarn package 3 laterally away from the first conveyor mechanism 1, so that it falls into the specially designed yarn package repair mechanism 8, and after processing, it enters the second conveyor mechanism 2; for the convex edge yarn package 3 entering the repair mechanism, firstly, the bottom round Hot air is introduced into the hot air channels 85 inside the shaped panel 83 and the top circular panel 84 to uniformly soften the fibers in the convex areas at both ends of the yarn package 3. Then, the hydraulic cylinder 82 drives the bottom circular panel 83 to slowly rise, and the yarn package 3 is clamped between the bottom and top circular panels 84 until the top of the yarn package 3 contacts the surface of the top circular panel 84. At this time, the bottom circular panel 83 continues to rise, and the annular panel 87 will descend, that is, the bottom yarn of the yarn package 3 is in close contact with the bottom circular panel 83. Under the combined action of hot air and pressure, the raised yarn is reshaped and flattened. After the repair is completed, the bottom circular panel 83 and the top circular panel 84 are reset, and the repaired yarn package 3 is pushed to the second conveying mechanism 2 for transport.
