Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and specifically refers to a textile yarn winding device. Background Art

[0002] In the textile industry, winding refers to the process of transferring and rewinding large-capacity yarn packages from roving frames, draw frames or other line sources onto bobbins for subsequent processes. This process aims to improve the uniformity, tension consistency and processability of the yarn, and provide high-quality yarn for subsequent weaving, knitting or other spinning processes. The typical winding process includes unwinding, yarn guiding, yarn clearing, winding, and bobbin changing. The quality of the winding process directly affects the efficiency of subsequent processes and the quality of the final product. Although modern winding machines have achieved automation and high speed, there are still some defects in actual production.

[0003] When a bobbin of a traditional winding machine is full and needs to be replaced, it usually requires manual operation to cut off the wire source and connect it to a new empty bobbin. The manual operation is slow, resulting in low production efficiency. In a textile factory, it is often necessary to operate multiple winding machines at the same time. The frequency of manual bobbin replacement is high, which consumes a lot of human resources and labor costs. Winding machines are dangerous when running at high speeds, and there are certain safety hazards during manual operation.

[0004] In order to solve this problem, some winding machines are equipped with automatic yarn cutting and joining devices. However, existing automatic yarn cutting and joining devices also have some shortcomings: existing automatic yarn cutting and joining devices often require a series of complex mechanical actions to complete the steps of yarn cutting, yarn suction, positioning, yarn joining, etc., such as the movement of the mechanical arm, the driving of the pneumatic components, etc. These actions result in a long pause time each time the bobbin is changed; at the same time, existing devices usually require the use of complex mechanical structures and sensor systems. For example, multiple motors, sensors, cylinders and other components are used to cooperate to complete the actions of yarn identification, clamping, cutting, conveying, etc., which not only increases the manufacturing cost of the equipment, but also makes the equipment more difficult to maintain and debug.

[0005] During the winding process, the yarn tension needs to be kept stable to ensure the uniformity and density of the yarn package. However, due to the change in the yarn winding radius and the superposition of the "climbing effect", it is difficult to keep the yarn tension constant during the winding process, which will lead to uneven density of the yarn package, tight outside and loose inside, affecting the quality of the final product. According to industry experience, the change of yarn tension during the winding process presents nonlinear dynamic characteristics. Specifically, in the initial stage (when the diameter of the bobbin is small), the yarn winding radius on the bobbin is small, and the yarn tension is mainly affected by the increase in the winding circumference. The tension increases relatively slowly, and the "climbing effect", that is, the additional resistance generated when the yarn climbs on the wound yarn layer, is also small; in the middle stage (when the diameter of the bobbin gradually increases), the tension growth rate accelerates, and the influence of the "climbing effect" gradually appears and becomes more and more significant; in the later stage (when the diameter of the bobbin is close to the maximum value), the tension growth rate tends to be flat. From the above description, although some winding machines are equipped with tension control devices, most of them are not stepless, but use a step-change method to adjust the tension. This method is obviously unable to adapt to the law of the above-mentioned tension change and is difficult to meet the needs of high-quality yarn production. Summary of the invention

[0006] In view of the above situation, the present invention provides a textile yarn winding device, which can realize fully automatic bobbin changing, eliminate manual operation, reduce labor costs, simplify yarn cutting and joining actions, simplify equipment structure, shorten bobbin changing time, improve equipment operation efficiency, adapt to the changing law of tension, and ensure the uniformity and density of yarn package.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a textile yarn winding device, comprising a vertical plate, a first servo motor is fixedly provided on one side of the vertical plate, the output end of the first servo motor is perpendicular to the vertical plate, a mounting plate is fixedly provided on the output end of the first servo motor, a support rod is fixedly provided on the outer edge of the mounting plate vertically and symmetrically, a second servo motor is fixedly provided on the outer side of one of the support rods, a rotating rod is closely provided on the inner side of the support rod, the output end of the second servo motor passes through the adjacent support rod and is fixedly connected to one end of the rotating rod on the inner side of the support rod, the rotating rod is in a horizontal state when the first servo motor is stationary, and the length direction of the rotating rod is parallel to the vertical plate when the second servo motor is stationary, a planetary speed-increasing constant tension winding mechanism is connected to the rotating rod and the support rod, the planetary speed-increasing constant tension winding mechanism is provided with a self-guided splicing mechanism on the upper and lower sides of the other end of the rotating rod, the self-guided splicing mechanism is symmetrically provided with a centrifugal self-locking bobbin driving mechanism on the upper end, a bobbin drop is provided above the centrifugal self-locking bobbin driving mechanism on the upper side, and a storage box is provided below the centrifugal self-locking bobbin driving mechanism on the lower side, and a yarn guide mechanism is fixedly provided on the same side of the vertical plate.

[0008] Furthermore, the planetary speed increaser constant tension winding mechanism includes a through slot, a first rotating shaft, a special-shaped gear and a second rotating shaft, the through slot being opened through the rotating rod, the opening direction of the through slot being perpendicular to the length direction of the rotating rod and parallel to the support rod, the first rotating shaft being vertically rotatable and arranged at a part of the rotating rod close to the support rod, a driving sprocket being coaxially fixed to the first rotating shaft in the through slot, a driven gear being coaxially fixed to the first rotating shaft on the outside of the rotating rod close to the rotating rod, the special-shaped gear being fixed to an edge of one of the support rods, the special-shaped gear and the driven gear being meshed and connected, the second rotating shaft being vertically rotatable and arranged at a part of the rotating rod away from the support rod, a driven sprocket being coaxially fixed to the second rotating shaft in the through slot, and a chain being cooperatively connected to the outside of the driven sprocket and the driving sprocket.

[0009] Furthermore, the self-guided cutting mechanism includes a chassis and a cutter, the chassis is coaxially symmetrically fixed at the upper and lower ends of the second rotating shaft, the chassis edge is fixed with guide spikes in a circular array, the root edges of adjacent guide spikes are connected, the cutter is fixed at the end of the rotating rod away from the support rod, the cutter is perpendicular to the length direction of the rotating rod, the cutter is located between the two chassis and arranged parallel to the chassis, and is used for cutting yarn, the cutter and the guide spikes intersect each other in the projection of the horizontal plane, so that the yarn can be guided to the cutting position by the guide spikes.

[0010] Furthermore, the centrifugal self-locking bobbin drive mechanism includes a positioning shaft, which is coaxially fixed on a side of the chassis facing away from the rotating rod, and a first circular groove is opened in a lateral circular array at one end of the positioning shaft away from the chassis, a first spring is fixedly provided at the bottom of the first circular groove, a first centrifugal shaft is fixedly provided at one end of the first spring, and the first centrifugal shaft is tightly slidably arranged in the first circular groove, a second circular groove is opened in the middle part of the positioning shaft in a lateral circular array, a second spring is fixedly provided at the bottom of the second circular groove, a second centrifugal shaft is fixedly provided at one end of the second spring, and the second centrifugal shaft is tightly slidably arranged in the second circular groove, and the outer ends of the first centrifugal shaft and the second centrifugal shaft are both hemispherically arranged.

[0011] Furthermore, the yarn guiding mechanism includes a bracket, which is symmetrically and vertically fixed on one side of the vertical plate, and a yarn guide roller is rotatably provided between the brackets to guide the yarn to be evenly wound on the bobbin, the yarn guide roller is vertically arranged, and a sliding column is fixed between the brackets, and a slider is tightly slidably provided on the sliding column, and the guide column end of the slider fits tightly with the yarn guide groove on the yarn guide roller, the yarn guide hole on the slider is horizontally arranged and parallel to the vertical plate, and the yarn guide hole on the slider always points to the part of the upper positioning axis close to the vertical plate, so that the yarn is always wound on the bobbin on the side of the bobbin facing the vertical plate.

[0012] Furthermore, each time the second servo motor rotates 180 degrees forward, it stops for the same period of time and then rotates 180 degrees in the opposite direction. The first servo motor rotates 180 degrees in the same direction during the time period each time the second servo motor stops. Each time the first servo motor rotates, it drives the positioning shaft away from the yarn guiding mechanism. The second servo motor realizes a winding of the yarn during this 180-degree forward rotation. Subsequently, during the time when the second servo motor stops, the first servo motor rotates to drive the second servo motor to flip 180 degrees. When the second servo motor is set to rotate in the opposite direction to this time next time, the winding direction driven by the second servo motor after being flipped is still the same as this time.

[0013] Furthermore, when the positioning shaft moves to a position away from the yarn guiding mechanism and is in a stationary state, it is coaxially arranged with the bobbin drop tube and is located directly above the storage box. The bobbin drop tube vertically falls during the time period from when the first servo motor stops to when the second servo motor is about to start, and there is a bobbin for winding, which is used for the next winding.

[0014] Furthermore, the diameter of the positioning shaft is smaller than the inner diameter of the bobbin, so that the bobbin can be sleeved on the positioning shaft after free fall, the diameter of the chassis is larger than the diameter of the positioning shaft, so that the yarn can contact the root edge of the guiding spike, and the diameter of the chassis is smaller than the outer diameter of the bobbin, so that the bobbin can press the yarn stuck at the root edge of the spike.

[0015] Furthermore, when the first spring is in an initial state, the cylindrical part of the first centrifugal shaft is entirely located in the first circular groove; when the first spring is reset, the arc surface on one side of the hemispherical end of the first centrifugal shaft can be tightly attached to the inner edge of the end of the bobbin sleeved on the positioning shaft, so that the hemispherical end of the first centrifugal shaft can press the bobbin to be tightly attached to the chassis; when the second spring is in an initial state, the hemispherical end of the second centrifugal shaft is entirely located in the second circular groove, so that the second centrifugal shaft will not block the falling of the bobbin.

[0016] Furthermore, the number of teeth of the special-shaped gear is greater than the number of teeth of the driven gear, and the diameter of the driving sprocket is greater than the diameter of the driven sprocket, thereby achieving accelerated rotation of the driven sprocket.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows:

[0018] (1) The present invention realizes automatic replacement of bobbins by setting a linkage between the first servo motor and the second servo motor without manual intervention. When the yarn is wound to a predetermined length, the second servo motor stops rotating and the first servo motor starts, driving the rotating rod to flip, flipping the fully loaded bobbin to the bottom and dropping it into the storage box. At the same time, the bobbin drops the new bobbin to the predetermined position, ready to start the next round of winding. This design completely eliminates the manual operation of bobbin replacement, greatly reduces dependence on manual labor, saves labor costs, and at the same time, since no manual intervention is required, it also avoids safety hazards caused by high operation frequency, thereby improving production safety.

[0019] (2) The present invention adopts a self-guided cutting and splicing mechanism, which realizes automatic cutting and positioning of the yarn through the cooperation of the guiding spikes, the cutter and the bobbin. Different from the complex mechanical actions of the traditional device, the present invention only requires a simple flip of the rotating rod to complete the whole process of cutting and splicing the yarn, which greatly simplifies the action process, shortens the bobbin changing time, and improves the equipment operation efficiency. At the same time, the self-guided cutting and splicing mechanism has a simple structure and does not require a complex sensor system and pneumatic components, which reduces the manufacturing cost and maintenance difficulty of the equipment.

[0020] (3) In the present invention, the distance between the bobbin and the yarn guide mechanism changes nonlinearly during the winding process. In the initial stage, the trajectory that is nearly parallel to the yarn guide mechanism causes the distance between the two to decrease slowly. In the middle stage, the trajectory that is nearly perpendicular to the yarn guide mechanism causes the distance between the two to decrease quickly. In the later stage, the trajectory that is nearly parallel to the yarn guide mechanism causes the distance to decrease slowly, thereby perfectly corresponding to the change in tension during the winding process in the opposite direction. Since the shortening of the guide distance can effectively reduce the tension value, it can effectively offset the "climbing effect" and the influence of the nonlinear increase in tension caused by the change in the yarn tube diameter, thereby achieving stable tension control, ensuring the uniformity and density of the yarn winding, and improving the quality of the final product.

When the second servo motor 4 is stationary, the length direction of the rotating rod 5 is parallel to the vertical plate 1. The rotating rod 5 and the support rod 31 are connected with a planetary speed-increasing constant-tension winding mechanism 6. The planetary speed-increasing constant-tension winding mechanism 6 is provided with a self-guided splicing mechanism 7 on the upper and lower sides of the other end of the rotating rod 5. The self-guided splicing mechanism 7 is symmetrically provided with a centrifugal self-locking bobbin drive mechanism 8 on the upper and lower ends. A drop tube 9 is provided above the centrifugal self-locking bobbin drive mechanism 8 on the upper side, and a storage box 11 is provided below the centrifugal self-locking bobbin drive mechanism 8 on the lower side. The vertical plate 1 is fixedly provided with a yarn guiding mechanism 10 on the same side.

[0036] Among them, the planetary speed increaser constant tension winding mechanism 6 includes a through slot 62, a first rotating shaft 63, a special-shaped gear 61 and a second rotating shaft 67. The through slot 62 is opened on the rotating rod 5, and the opening direction of the through slot 62 is perpendicular to the length direction of the rotating rod 5 and parallel to the support rod 31. The first rotating shaft 63 is vertically rotatable and arranged at the part of the rotating rod 5 close to the support rod 31. The first rotating shaft 63 is coaxially fixed with a driving sprocket 64 in the through slot 62. The first rotating shaft 63 is coaxially fixed with a driven gear 65 on the outside of the rotating rod 5, close to the rotating rod 5. The special-shaped gear 61 is fixed at the edge of one of the support rods 31, and the special-shaped gear 61 and the driven gear 65 are meshed and connected. The second rotating shaft 67 is vertically rotatable and arranged at the part of the rotating rod 5 away from the support rod 31. The second rotating shaft 67 is coaxially fixed with a driven sprocket 68 in the through slot 62, and a chain 66 is matched with the outside of the driven sprocket 68 and the driving sprocket 64.

[0037] Among them, the self-guided cutting mechanism 7 includes a chassis 71 and a cutter 73. The chassis 71 is coaxially symmetrically fixed at the upper and lower ends of the second rotating shaft 67. A circular array of guiding ribs 72 is fixed on the edge of the chassis 71. The root edges of adjacent guiding ribs 72 are connected. The cutter 73 is fixed at the end of the rotating rod 5 away from the support rod 31. The cutter 73 is perpendicular to the length direction of the rotating rod 5. The cutter 73 is located between the two chassis 71 and is arranged parallel to the chassis 71. The cutter 73 and the guiding ribs 72 intersect each other in the projection of the horizontal plane.

[0038] Among them, the centrifugal self-locking bobbin drive mechanism 8 includes a positioning shaft 81, which is coaxially fixed on the side of the chassis 71 facing away from the rotating rod 5. The end of the positioning shaft 81 away from the chassis 71 is provided with a first circular groove 83 in a lateral circular array, and a first spring 85 is fixed at the bottom of the first circular groove 83. A first centrifugal shaft 84 is fixed at one end of the first spring 85. The first centrifugal shaft 84 is tightly slidably arranged with the first circular groove 83. A second circular groove 82 is opened in the middle part of the positioning shaft 81 in a lateral circular array, and a second spring 87 is fixed at the bottom of the second circular groove 82. A second centrifugal shaft 86 is fixed at one end of the second spring 87. The second centrifugal shaft 86 is tightly slidably arranged with the second circular groove 82. The outer ends of the first centrifugal shaft 84 and the second centrifugal shaft 86 are both hemispherical.

[0039] Among them, the yarn guiding mechanism 10 includes a bracket 101, which is symmetrically and vertically fixed on one side of the vertical plate 1, a yarn guiding roller 102 is rotatably arranged between the brackets 101, and the yarn guiding roller 102 is vertically arranged, and a sliding column 103 is fixed between the brackets 101, and a slider 104 is tightly slidably arranged on the sliding column 103, and the guide column end of the slider 104 is tightly fitted with the yarn guiding groove on the yarn guiding roller 102, and the yarn guiding hole on the slider 104 is horizontally arranged and parallel to the vertical plate 1, and the yarn guiding hole on the slider 104 always points to the part of the upper positioning shaft 81 close to the vertical plate 1, and the second servo motor 4 stops for the same time after each forward rotation of 180 degrees and then rotates 180 degrees in the opposite direction, and the first servo motor 2 rotates 180 degrees in the same direction during the time period each time the second servo motor 4 stops, and the first servo motor 2 drives the positioning shaft 81 away from the yarn guiding mechanism 10 each time it rotates.

[0040] Among them, when the positioning shaft 81 moves to a position away from the yarn guiding mechanism 10 and is in a stationary state, it is coaxially arranged with the bobbin drop tube 9 and is located directly above the storage box 11. The bobbin drop tube 9 falls vertically in the time period from when the first servo motor 2 stops to when the second servo motor 4 is about to start, and there is a bobbin for winding. The diameter of the positioning shaft 81 is smaller than the inner diameter of the bobbin, the diameter of the chassis 71 is larger than the diameter of the positioning shaft 81, and the diameter of the chassis 71 is smaller than the outer diameter of the bobbin. When the first spring 85 is in the initial state, the cylindrical part of the first centrifugal shaft 84 is completely located in the first circular groove 83. When the first spring 85 is reset, the arc surface on one side of the hemispherical end of the first centrifugal shaft 84 can be tightly attached to the inner edge of the end of the bobbin sleeved on the positioning shaft 81. When the second spring 87 is in the initial state, the hemispherical end of the second centrifugal shaft 86 is completely located in the second circular groove 82. The number of teeth of the special-shaped gear 61 is greater than the number of teeth of the driven gear 65, and the diameter of the driving sprocket 64 is greater than the diameter of the driven sprocket 68.

[0041] When starting to use, the vertical plate 1 is fixed vertically, the first servo motor 2 and the second servo motor 4 are stopped, and the rotating rod 5 is in a horizontal state under the control of the first servo motor 2. The two centrifugal self-locking bobbin drive mechanisms 8 are respectively located on the upper and lower sides of the rotating rod 5. A bobbin ready for winding is already sleeved on the upper positioning shaft 81. The first centrifugal shaft 84 is in a reset state under the action of the first spring 85. There is no bobbin on the lower positioning shaft 81, and the bobbin to be used is placed in the bobbin 9. The yarn guide roller 102 of the yarn guide mechanism 10 guides the yarn into the working area, and the yarn guide hole on the slider 104 is aligned with the side of the upper positioning shaft 81 close to the vertical plate 1. When used for the first time, one end of the yarn is fixed to the bobbin on the side of the bobbin facing the vertical plate 1 for easy winding.

[0042] When winding begins, the second servo motor 4 starts, driving the rotating rod 5 to rotate 180 degrees. The rotation of the rotating rod 5 drives the driven gear 65 to mesh and rotate with the fixed special-shaped gear 61, and then drives the second rotating shaft 67 and the positioning shaft 81 to rotate through the active sprocket 64, the chain 66, and the driven sprocket 68. During the rotation of the positioning shaft 81, the second centrifugal shaft 86 moves outward under the action of centrifugal force, so that its hemispherical end contacts the inner wall of the bobbin and drives the bobbin to rotate together through friction. Since the yarn guide hole on the slider 104 is always aligned with the side of the positioning shaft 81 close to the vertical plate 1, the yarn is wound onto the bobbin. The rotation trajectory of the rotating rod 5 is semicircular, so that the bobbin gradually approaches the yarn guide mechanism 10 during the winding process. The advantages brought by this motion trajectory are: The trajectory of the yarn guiding mechanism 10 is close to being parallel, so that the distance between the two decreases slowly. The trajectory of the yarn guiding mechanism 10 is close to being perpendicular to the yarn guiding mechanism 10 in the middle stage, so that the distance between the two decreases quickly. The trajectory of the yarn guiding mechanism 10 is close to being parallel to the yarn guiding mechanism 10 in the late stage, so that the distance decreases slowly, thereby perfectly corresponding to the change of tension in the winding process in the opposite direction. Since the shortening of the guiding distance can effectively reduce the tension value, it can effectively offset the "climbing effect" described in the background technology and the influence of the nonlinear increase in tension caused by the change in the yarn tube diameter, thereby ensuring the uniformity and density of the yarn winding. The yarn guiding mechanism 10 realizes the up and down reciprocating movement of the slider 104 to guide the uniform winding by slidingly connecting the guide post end of the slider 104 with the guide groove on the guide roller 102. It is the basic structure of a conventional winding device, so its structural principle will not be repeated.

[0043] The sizes of the special-shaped gear 61, the driven gear 65, the driving sprocket 64 and the driven sprocket 68 are reasonably set to realize the accelerated rotation of the positioning shaft 81, so that when the bobbin moves to one end close to the yarn guide mechanism 10, the yarn is just wound to a predetermined length, and the second servo motor 4 stops rotating. At this time, the first servo motor 2 starts, driving the rotating rod 5 to flip 180 degrees, so that the upper and lower positions of the two positioning shafts 81 are interchanged. During the flipping of the rotating rod 5, the fully wound bobbin gradually moves away from the yarn guide mechanism 10 as the positioning shaft 81 flips, and is finally located at the bottom. During the flipping of the fully loaded bobbin, the yarn is guided by the guide spike 72 on the same side. The yarn contacts the cutter 73 and moves to the position where the root edge of the guide spike 72 is connected under the guidance of another guide spike 72. After the bobbin is completely inverted, the yarn is located on the upper side of the upper chassis 71 and stabilized close to the positioning shaft 81 on the side of the positioning shaft 81 facing the vertical plate 1. By reasonably setting the size relationship between the positioning shaft 81 and the chassis 71, the yarn can be stuck in the narrow gap at the root edge of the two guide spikes 72. At this time, since the bobbin below is fully loaded and has a large weight, and its weight directly acts on the hemispherical end of the protruding first centrifugal shaft 84 after it is vertically downward, coupled with the inertia of the rotating rod 5 after it stops, the lower end of the bobbin will The hemispherical end of the first centrifugal shaft 84 is pressed into the first circular groove 83, and after the centrifugal force is lost, the second centrifugal shaft 86 no longer restrains the bobbin, so that the bobbin falls into the storage box 11, and at the moment of falling, the yarn contacting the cutter 73 is pulled down to cut the yarn. At the same time, the upper bobbin 9 freely drops a new bobbin, and the bobbin with a falling speed comes to the corresponding positioning shaft 81, presses the hemispherical end of the first centrifugal shaft 84 in contact into the first circular groove 83 and continues to fall onto the chassis 71. At this time, after the first spring 85 is reset, the arc surface of the hemispherical end of the first centrifugal shaft 84 presses the bobbin down and presses it tightly against the chassis 71, thereby The yarn is compressed, and the dimensions of the chassis 71 and the outer diameter of the bobbin are reasonably set so that the bobbin can ensure that the yarn is compressed. Then the second servo motor 4 is started in reverse. Since the rotating rod 5 has been flipped once, the rotating rod 5 moves in the same direction as the last time after the second servo motor 4 is started in reverse, thereby starting a new round of yarn winding process. One end of the yarn is bound so that it can be smoothly wound on the bobbin. The control of the first servo motor 2 and the second servo motor 4 in the present invention can be achieved by using a PLC control system, which is an existing conventional technical means and can accurately control the rotation angle, speed and time of the first servo motor 2 and the second servo motor 4.
