Description

Technical Field

[0001] This invention relates to the field of yarn tube conveying, and more specifically to a high-speed winding machine yarn tube conveying device. Background Technology

[0002] In high-speed automatic winding machine systems, bobbins, i.e., yarn tubes wound with yarn, are typically transported from the yarn storage area or yarn supply platform to each unwinding spindle position via a suspended conveyor. This conveying method generally uses a hanging rail, chain, or trolley to clamp the upper end of the bobbin, making it run along the track in an inverted or upright state to achieve continuous and efficient automatic yarn feeding.

[0003] However, in existing technologies, suspension mechanisms mostly use simple hooks, elastic clips, or open slots to position the yarn tubes, lacking an effective posture constraint mechanism. During high-speed conveying, start-stop, or turning, the yarn tubes are prone to swaying or even axial displacement, resulting in incorrect positioning, angular deviation, or yarn end disorder when they reach the unwinding station. This affects the accurate docking of the subsequent automatic yarn insertion mechanism, reduces the success rate of yarn insertion, and impacts unwinding.

[0004] Therefore, there is a need for a high-speed winding machine yarn conveying device to effectively suppress the shaking and deviation of the yarn during the conveying process, improve its posture stability and positioning accuracy, thereby ensuring that the yarn accurately and reliably connects to the unwinding spindle seat, and improve the success rate of automatic yarn insertion and the overall machine operating efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, a high-speed winding machine yarn conveying device is provided. By coordinating the upper and lower limit ring and the elastic clamp, a two-way constraint of axial buffering and limiting and radial elastic support is formed, which effectively suppresses the movement, rotation and swaying of the yarn during high-speed conveying and ensures stable and reliable posture.

[0006] To address the problems of existing technologies, this invention provides a high-speed winding machine bobbin conveying device, comprising a frame and a suspended conveyor chain mounted on the frame. A plurality of hangers are evenly spaced along the conveying direction on the suspended conveyor chain. Each hanger includes a connector, fixedly mounted on the suspended conveyor chain, and has a horizontally extending outward support plate, a vertically positioned rod, the upper end of which is fixedly connected to the support plate, and the lower end extending vertically downward. An elastic clamp is detachably mounted on the lower end of the rod. The lower end of the rod has an external thread section. A threaded sleeve is provided that mates with the external threaded section. The threaded sleeve is circumferentially distributed with a plurality of strip-shaped buckles integrally formed therewith. The strip-shaped buckles extend axially along the threaded sleeve. Each strip-shaped buckle is elastic at its connection with the threaded sleeve. A limiting top ring is fixedly disposed on the upper half of the suspension rod. The lower end of the limiting top ring has a contact surface that matches the yarn tube port. When the yarn tube is inserted upward to its upper port and fits against the contact surface of the limiting top ring, the strip-shaped buckles are in a radially expanding internal support state under the constraint of the inner wall of the yarn tube.

[0007] Preferably, the outer surface of each of the strip buckles is provided as a guide slope that slopes inward from top to bottom.

[0008] Preferably, a spherical groove is provided on the guide slope, and a ball bearing that rolls with it is embedded in the spherical groove.

[0009] Preferably, a pressing block is provided at the lower end of the boom and inside the elastic clamp. The pressing block can move along the axial direction of the boom. The upper half of each strip buckle is provided with an inwardly protruding pressing part. When the pressing block moves downward and abuts against each of the pressing parts, the strip buckle is in a radially rigid locking state.

[0010] Preferably, the pressing part is a wedge block, which is fixedly connected to the corresponding strip buckle by bolts. The pressing block has a ring structure and its outer periphery is provided with a conical surface that matches the inclined surface of each wedge block.

[0011] Preferably, a gap is left between the pressing block and each of the strip buckles to provide space for the strip buckles to freely deform inward elastically.

[0012] Preferably, the boom is a hollow cylinder that runs vertically through the shaft. Inside the boom is an axially movable rod. The lower end of the movable rod is fixedly connected to a pressing block, and the upper end is provided with an anti-detachment ring. A compression spring is provided between the anti-detachment ring and the boom, and is sleeved on the movable rod. One end of the compression spring is fixedly connected to the anti-detachment ring, and the other end is fixedly connected to the boom.

[0013] Preferably, the frame is provided with a fixed plate above the movable rod along the conveying direction of the suspended conveyor chain. The fixed plate is horizontally arranged and has a guide slope at the starting position of the bobbin feeding. When the hoist passes the fixed plate, the movable rod is in a downward pressing state, so that the pressing block abuts against each pressing part.

[0014] Preferably, the frame is provided with limiting guide rails located on the upper and lower sides of the support plate along the conveying direction of the suspended conveyor chain, and the upper and lower ends of the support plate are respectively provided with rollers that roll in contact with the corresponding limiting guide rails.

[0015] Preferably, the limiting top ring is made of rubber and forms an elastic contact surface with buffering and anti-slip functions when it contacts the upper end of the yarn tube.

[0016] The advantages of this application compared to the prior art are:

[0017] 1. This invention utilizes a limiting top ring located on the upper half of the boom. When the upper end of the yarn tube contacts the limiting top ring, an elastic contact surface with buffering and high friction characteristics is formed, effectively suppressing axial movement and circumferential rotation of the yarn tube during transport. As the yarn tube is fitted onto the elastic clamp from bottom to top, the elastic clamp radially tightens the inner hole of the yarn tube through its circumferentially distributed strip-shaped buckles, providing a stable and reliable clamping force. The combined action of the limiting top ring and the elastic clamp creates bidirectional constraint, ensuring the yarn tube maintains stable posture during high-speed operation, start-stop, and turning conditions, thus improving the smoothness and reliability of the suspended transport.

[0018] 2. This invention achieves automatic switching of the yarn clamping state by incorporating a movable rod reset by a compression spring and a connecting pressure block within the suspension rod, in conjunction with the pressure part inside the strip-shaped buckle. During feeding, the pressure block is in a high position, allowing the strip-shaped buckle to deform freely, facilitating smooth insertion of the yarn tube. After entering the conveying zone, the fixed plate presses down the movable rod, causing the pressure block to descend and engage with the pressure part, mechanically locking the strip-shaped buckle in a radially rigid, tensioned state. This effectively suppresses the loosening of the elastic buckle due to vibration, sudden stops, or turns during high-speed operation, improving the stability of the yarn tube suspension and the reliability of conveying, ensuring accurate unwinding.

[0019] 3. This invention constructs a bidirectional rolling constraint structure by setting rollers at the upper and lower ends of the support plate and forming a rolling engagement with the corresponding upper and lower limit guide rails on the frame. When the hanger moves with the suspended conveyor chain, the rollers roll smoothly along the limit guide rails, effectively suppressing the vertical jump and horizontal sway of the support plate, avoiding swaying and deflection caused by vibration, acceleration, deceleration, or turning of the suspended conveyor chain. This ensures that the hanger and the suspended yarn tube always maintain a stable posture, providing reliable mechanical guidance for high-speed, high-precision automatic yarn feeding and unwinding.

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1 to 8 As shown, a high-speed winding machine yarn conveying device includes a frame 1 and a suspended conveyor chain 2 mounted on the frame 1. A plurality of hangers 3 are evenly spaced along the conveying direction on the suspended conveyor chain 2. Each hanger 3 includes a connector 31, fixedly mounted on the suspended conveyor chain 2, and has a horizontally extending support plate 311. A vertically positioned rod 32 is fixedly connected to the support plate 311 at its upper end and extends vertically downward at its lower end. An elastic clip 33 is detachably mounted at the lower end of the rod 32. The lower end of the rod 32 has an external threaded section. The elastic clip 33 has a threaded sleeve 331 that threadedly engages with the external threaded section. The threaded sleeve 331 is circumferentially distributed with a plurality of integrally formed strip-shaped buckles 332. The strip-shaped buckles 332 extend axially along the threaded sleeve 331, and each strip-shaped buckle 332 is elastic at its connection with the threaded sleeve 331. The limiting top ring 34 is fixedly installed on the upper half of the hanging rod 32. The lower end of the limiting top ring 34 has a contact surface that matches the port of the yarn tube 6. When the yarn tube 6 is inserted upward to its upper port and fits against the contact surface of the limiting top ring 34, the strip buckle 332 is in a radially expanding inner support state under the constraint of the inner wall of the yarn tube 6.

[0035] Before the yarn tube 6 conveying operation begins, the lifting device 3 moves to the loading area along with the suspended conveyor chain 2. At this time, the lifting device 3 is in its initial state: the lifting rod 32 is vertically suspended below the support plate 311, and its lower end is fitted with an elastic clamp 33 via a threaded connection. The threaded sleeve 331 of the elastic clamp 33 has multiple axially extending strip-shaped buckles 332 evenly distributed around its circumference. Each strip-shaped buckle 332 is elastic at its root and is in a natural state. At the same time, the limiting top ring 34 located on the upper half of the lifting rod 32 is stationary at a preset height, with its lower end facing downwards and not in contact with any object.

[0036] After the yarn feeding mechanism pushes a tube of yarn 6 wrapped with yarn directly below the lifting device 3, the lifting platform or yarn insertion actuator pushes the tube of yarn 6 upward along the axis of the lifting rod 32. The tube of yarn 6 first approaches the elastic clip 33, and the edge of its inner orifice contacts the strip-shaped clip 332. As the tube of yarn 6 continues to rise, the inner wall of the orifice applies radial inward pressure to the strip-shaped clip 332, forcing each strip-shaped clip 332 to overcome its own elastic deformation capacity and synchronously retract towards the center, reducing the overall outer contour and thus smoothly sliding into the internal cavity of the tube of yarn 6. During this process, the strip-shaped clips 332 undergo temporary compression due to the elasticity of the material, but no plastic damage occurs.

[0037] When the yarn tube 6 continues to move upward until its top end face is completely in contact with the lower end of the limiting top ring 34, the upward movement stops. At this point, the axial position of the yarn tube 6 is precisely limited by the limiting top ring 34, preventing it from continuing to move upward. Simultaneously, since the inner wall of the yarn tube 6 no longer exerts inward pressure on the strip-shaped buckles 332, each strip-shaped buckle 332 quickly rebounds outward under the action of the elastic restoring force at its root, and its outer surface tightly adheres to the inner wall of the yarn tube 6, forming a uniformly distributed radial tension force. This tension force is sufficient to resist inertial disturbances caused by acceleration, turning, or vibration during subsequent conveying, ensuring that the yarn tube 6 will not loosen.

[0038] At this point, the yarn tube 6 is securely suspended on the hanger 3: axial positioning is provided above by the limiting top ring 34 to prevent it from moving up and down. Radial clamping is provided below by the elastic clamp 33 to prevent it from swinging or rotating. Subsequently, the suspended conveyor chain 2 starts, driving the entire row of hangers 3 forward along the track on the frame 1. Throughout the conveying process, the yarn tube 6 maintains a stable posture, with its axis coinciding with the hanger 32, without significant swaying or skew.

[0039] When the lifting device 3 arrives at the unwinding station, the yarn insertion mechanism supports the bottom of the yarn tube 6 from below and clamps the yarn tube 6 to make it disengage downwards from the elastic clamp 33. During this process, the inner hole of the yarn tube 6 presses the strip buckle 332 again to make it close up, completing the unwinding and fully meeting the stringent requirements of the high-speed winding machine for the conveying accuracy and efficiency of the yarn tube 6.

[0040] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, the outer surface of each of the strip buckles 332 is provided as a guide slope 3321 that slopes inward from top to bottom.

[0041] As the yarn tube 6 is inserted upward into the lifting device 3, its inner hole first contacts the strip-shaped buckle 332 of the elastic clip 33. Since the outer surface of each strip-shaped buckle 332 is designed as a guide slope 3321 that slopes inward from top to bottom, when the edge of the yarn tube 6 end contacts the guide slope 3321, the guide slope 3321 converts part of the axial thrust applied by the yarn tube 6 into a radial component, guiding the strip-shaped buckle 332 to smoothly converge towards the center.

[0042] As the yarn tube 6 continues to rise, a continuous sliding fit is formed between the guide slope 3321 and the inner wall of the yarn tube 6, ensuring that the strip buckle 332 deforms evenly and with low resistance during the compression process, thus avoiding sudden jamming or local stress concentration. This not only reduces the thrust required for insertion but also ensures that yarn tubes 6 of different sizes or with minor tolerances can be smoothly fitted in, improving the compatibility and reliability of the feeding process.

[0043] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, a spherical groove is provided on the guide slope 3321, and a ball bearing 3322 is embedded in the spherical groove to roll and cooperate with it.

[0044] During the upward insertion of the yarn tube 6 into the elastic clip 33, the inner wall of the yarn tube 6 comes into contact with the ball bearing 3322 protruding from the surface of the spherical groove. Under the thrust of the yarn tube 6, the ball bearing 3322 rotates freely along the spherical groove, converting the original sliding friction into rolling friction and reducing insertion resistance. This process allows the yarn tube 6 to be fitted onto the clip more smoothly and stably, avoiding jamming, misalignment, or damage to the yarn tube 6 caused by excessive friction.

[0045] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, a pressing block 321 is provided at the lower end of the boom 32 and inside the elastic clip 33. The pressing block 321 can move along the axial direction of the boom 32. The upper half of each strip buckle 332 is provided with an inwardly protruding pressing part 322. When the pressing block 321 moves downward and abuts against each of the pressing parts 322, the strip buckle 332 is in a radially rigid locking state.

[0046] After the yarn tube 6 is inserted and initially clamped by the elastic clip 33, the lifting device 3 enters the stable conveying section along the suspended conveyor chain 2. At this time, the pressure block 321 located at the lower end of the lifting rod 32 and inside the elastic clip 33 begins to function. The pressure block 321 can move freely along the axial direction of the lifting rod 32. As the pressure block 321 descends, its working surface gradually approaches the inwardly protruding pressure part 322 of each strip-shaped buckle 332.

[0047] As the pressing block 321 continues to move downward and fully abuts against all the pressing parts 322, an inward restraining force is applied to each strip buckle 332, preventing its root from elastically bending inward or unexpectedly retracting due to vibration, impact, or inertia. At this time, the strip buckles 332, which originally relied on their own elasticity, are mechanically limited, and the whole enters a radially rigid locking state. That is, although they still maintain the tension force on the inner hole of the yarn tube 6, they have lost the ability to deform further. Thus, they maintain suspension stability under dynamic conditions such as high-speed conveying, emergency stop, or turning, effectively preventing the yarn tube 6 from loosening, shifting, or falling off, and ensuring accurate docking in the subsequent unwinding process.

[0048] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, the pressing part 322 is specifically a wedge block, which is fixedly connected to the corresponding strip buckle 332 by bolt 3221. The pressing block 321 has a ring structure, and its outer periphery is provided with a conical surface that matches the inclined surface of each wedge block.

[0049] As the pressing block 321 moves downward along the lifting rod 32, its outer conical surface begins to contact the inclined surface of the wedge on each strip-shaped buckle 332. Since each pressing part 322 is an independent wedge and is rigidly connected to the inner side of the corresponding strip-shaped buckle 332 by bolts 3221, the inclined surface of the wedge faces the center and the angle precisely matches the conical surface of the pressing block 321.

[0050] Because the conical surface perfectly fits the multiple wedges, the force is evenly distributed during the pressing process, avoiding single-point uneven loading and ensuring that all strip buckles 332 synchronously enter a stable locking state. This not only improves clamping rigidity but also enhances the ability of the yarn tube 6 to resist vibration and impact during high-speed transport.

[0051] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, there is a gap between the pressing block 321 and each of the strip buckles 332 to provide space for the strip buckles 332 to freely deform inward.

[0052] In the initial stage of yarn feeding 6, the pressure block 321 is located at the upper limit of its stroke. At this time, a certain distance is maintained between the outer peripheral conical surface of the pressure block 321 and the wedge-shaped inclined surface on the inner side of each strip buckle 332. More importantly, a radial gap is reserved between the pressure block 321 and the body of each strip buckle 332.

[0053] When the yarn tube 6 is inserted into the elastic clip 33 from bottom to top, the inner wall of the clip applies inward pressure to the outer side of the strip clip 332, forcing the strip clip 332 to elastically bend around its root and converge towards the center. Due to the existence of this gap, the strip clip 332 is not interfered with or blocked by the pressure block 321 during the compression deformation process, and can freely and smoothly complete the inward elastic deformation, thereby allowing the yarn tube 6 to be smoothly inserted into the predetermined position.

[0054] See Figure 6 , Figure 9 , Figure 10 and Figure 12 As shown, the lifting rod 32 is a hollow cylinder that runs vertically through the shaft. Inside the lifting rod 32, there is an axially movable rod 323. The lower end of the movable rod 323 is fixedly connected to the pressing block 321, and the upper end is provided with an anti-detachment ring 3231. Between the anti-detachment ring 3231 and the lifting rod 32, there is a compression spring 3232 sleeved on the movable rod 323. One end of the compression spring 3232 is fixedly connected to the anti-detachment ring 3231, and the other end is fixedly connected to the lifting rod 32.

[0055] When the lifting device 3 is in the loading preparation state, the movable rod 323 is located at the upper limit position in the cavity of the lifting rod 32. At this time, the compression spring 3232 sleeved on the outer periphery of the movable rod 323 is in a free state. Since the lower end of the movable rod 323 is rigidly connected to the pressing block 321, the pressing block 321 is raised to a high position, so that its conical surface is away from the wedges on the inner side of each strip buckle 332, thereby forming a sufficient gap between the pressing block 321 and the strip buckle 332, allowing the strip buckle 332 to freely deform inward elastically when the yarn tube 6 is inserted.

[0056] When the anti-detachment ring 3231 overcomes the compression spring 3232, it forces the movable rod 323 to move axially downward along the inner cavity of the lifting rod 32. The movable rod 323 drives the pressing block 321 to move downward synchronously, so that its conical surface gradually contacts and presses against the inclined surfaces of each wedge block, and finally locks the strip buckle 332 in a radially rigid locking state.

[0057] See Figures 7 to 12 As shown, a fixed plate 4 is provided on the frame 1 along the conveying direction of the suspended conveyor chain 2, located above the movable rod 323. The fixed plate 4 is horizontally arranged, and a guide slope is provided at the starting position of the yarn tube 6. When the hoist 3 passes the fixed plate 4, the movable rod 323 is in a downward state, so that the pressing block 321 abuts against each pressing part 322.

[0058] At the initial feeding position, the lifting device 3 has not yet contacted the fixed strip 4. The movable rod 323 is in the upper position under the action of the compression spring 3232. The pressing block 321 is disengaged from the pressing part 322, and the strip buckle 332 can freely and elastically deform, making it easy for the yarn tube 6 to be put into the elastic clip 33 from bottom to top.

[0059] When the lifting device 3 moves with the suspended conveyor chain 2 to the guide slope of the fixed strip plate 4, the top of the movable rod 323 is gradually pressed down by the slope of the guide slope. After entering the straight section of the fixed strip plate 4, the movable rod 323 remains pressed down, so that the pressing block 321 presses tightly against each wedge-shaped pressing part 322, locking the strip buckle 332 in the radially tightened position, ensuring that the tube yarn 6 is stable and does not shake during the conveying process.

[0060] After reaching the unloading endpoint, the lifting device 3 detaches from the fixed strip 4, and the movable rod 323 rises back under the restoring force of the compression spring 3232, releasing the lock and preparing for the next round of loading.

[0061] See Figures 9 to 12 As shown, the frame 1 is provided with limiting guide rails 5 located on the upper and lower sides of the support plate 311 along the conveying direction of the suspended conveyor chain 2. The upper and lower ends of the support plate 311 are respectively provided with rollers 51 that roll in contact with the corresponding limiting guide rails 5.

[0062] When the suspended conveyor chain 2 drives the lifting device 3 along the frame 1, the connecting piece 31 fixed on the suspended conveyor chain 2 moves forward accordingly, and its horizontally extending support plate 311 moves synchronously. At this time, the rollers 51 installed at the upper and lower ends of the support plate 311 keep in contact with the corresponding limit guide rails 5 set on the frame 1.

[0063] As the suspended conveyor chain 2 operates continuously, the rollers 51 roll along the surfaces of the corresponding upper and lower limit guide rails 5, forming a two-way rolling constraint. This effectively limits the vertical jump and horizontal sway of the support plate 311, preventing the hanger 3 from swaying or deflecting due to the inertial force generated by the vibration, acceleration, deceleration, or turning of the suspended conveyor chain 2. At the same time, it maintains the stability of the posture of the hanger rod 32 and the suspended yarn tube 6, providing a reliable mechanical guiding foundation for high-precision automatic yarn feeding and unwinding.

[0064] See Figure 9 and Figure 10 As shown, the limiting top ring 34 is made of rubber and forms an elastic contact surface with buffering and anti-slip functions by contacting the upper end of the yarn tube 6.

[0065] As the yarn tube 6 is inserted into the lifting device 3 from bottom to top and nears its final position, the top surface of the yarn tube 6 lightly touches the lower surface of the limiting top ring 34. Because the limiting top ring 34 is made of rubber, it has good elasticity and a high coefficient of friction. Upon contact, the rubber material undergoes localized compression deformation under the pressure of the yarn tube 6's end face, forming a tightly fitting elastic contact surface. This process effectively absorbs the impact energy from the upward-moving end of the yarn tube 6, preventing damage or positioning misalignment caused by rigid collisions.

[0066] Meanwhile, the static friction between the rubber surface and the end face of the yarn tube 6 enhances the axial and circumferential constraint capabilities, preventing the yarn tube 6 from undergoing slight axial movement or rotation around the axis due to vibration or acceleration changes during subsequent high-speed transport.

[0067] This invention utilizes a rubber limiting top ring 34 on the upper half of the rod 32 to form an elastic contact surface with the upper end of the yarn tube 6, providing buffering and high friction characteristics, effectively suppressing axial movement and circumferential rotation during transport. Simultaneously, the strip-shaped buckle 332 of the elastic clamp 33 can freely deform inwards when the yarn tube 6 is inserted, radially tightening the inner hole of the yarn tube 6 to provide clamping force. Upon entering the transport section, the fixed plate 4 presses down the movable rod 323, causing the pressure block 321 to descend, so that its conical surface fits against the inclined surface of the wedge block inside the strip-shaped buckle 332, mechanically locking the strip-shaped buckle 332 in a rigidly tightened state, preventing loosening due to vibration, sudden stops, or turns.

[0068] In addition, rollers 51 are provided at the upper and lower ends of the support plate 311, which roll in cooperation with the corresponding upper and lower limit guide rails 5 on the frame 1. During the conveying process, the vertical jump and horizontal swing of the support plate 311 are restrained, ensuring the stability of the hanging rod 32 and the yarn tube 6. This ensures that the yarn tube 6 is accurately positioned and reliably suspended during high-speed operation, meeting the stringent requirements of automatic yarn feeding and unwinding.

[0069] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
