Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a winding machine with a bobbin rotation and replacement function. Background Technology

[0002] In existing automatic winding machines, the process of changing the winding spool still faces an efficiency bottleneck. Although some equipment has achieved automated operation, changing the winding spool still requires first removing the already wound spool from the workstation and then installing a new empty spool at the winding position. This process necessitates stopping the equipment, affecting continuous production. Especially in high-frequency spool changing environments, repeated shutdowns, disassembly, and installation not only reduce production efficiency but may also increase equipment wear due to frequent mechanical movements. Furthermore, traditional automatic spool changing mechanisms typically employ a single-station design, relying on robotic arms or conveyor belts to pick up and place the winding spool. Their spool changing speed is limited by the operating cycle of the robotic arm or conveyor system, making it difficult to meet the demands of high-speed production. Summary of the Invention

[0003] To address the problems of existing technologies, a winding machine with a rotating and interchangeable bobbin function is provided. By integrating a winding station and a loading / unloading station on a rotary table, and configuring interchangeable positioning fixtures at both stations, continuous operation of the winding process is achieved. After the winding station completes the wire winding, the rotary table rotates 180°, exchanging the positions of the empty bobbin at the loading / unloading station with the finished bobbin at the winding station. At this time, the wire remains in a bridging state, and the rotating abutment joint automatically presses and positions the new bobbin while maintaining wire tension. The wire cutting mechanism then cuts the connecting wire between the two stations, and the rotating abutment joint drives the new bobbin to start the winding operation. Meanwhile, the finished bobbin at the loading / unloading station can be unloaded and the new bobbin can be clamped simultaneously. This solves the problem that existing automatic winding machines require the removal of the finished bobbin before the installation of a new bobbin, which would affect continuous production.

[0004] To address the problems of existing technologies, this invention provides a winding machine with a rotating and changing function for the winding drum, comprising: a rotary table with loading / unloading stations and winding stations spaced circumferentially; a rotary positioning assembly including two positioning fixtures symmetrically arranged at the loading / unloading stations and the winding stations, wherein the winding station is provided with an abutting rotating head driven to connect with the winding drum, and the positioning fixture has a clamping part for fixing the inner wall of the winding drum; the rotary table rotates to drive the two positioning fixtures to interchange positions; and a loading / unloading system including a robotic arm located at the loading / unloading station. It is used to perform a combined action of unloading the finished winding drum and loading the new winding drum; the wire cutting mechanism has its cutting edge located on the vertical line of the line connecting the loading / unloading station and the winding station; the working end face of the positioning fixture is provided with a flange that can dock with the end of the winding drum. When the positioning fixture at the winding station rotates to the loading / unloading station, the wire is crossed between the flange and the end of the winding drum. When the abutting rotating head abuts against the other end of the winding drum, the flange and the end of the winding drum clamp the wire and trigger the wire cutting mechanism to cut the wire.

[0005] Preferably, the positioning fixture further includes a rotating seat, rotatably mounted on the rotary table, with one end face forming the flange; a positioning shaft, coaxially fixedly connected to the rotating seat; and an inner abutment assembly, distributed circumferentially along the positioning shaft, for radially abutting the inner wall of the winding drum.

[0006] Preferably, the inner abutment assembly includes an abutment arm, which is arranged parallel to the positioning shaft; and an elastic connector, which is disposed between the abutment arm and the positioning shaft, for making the abutment arm elastically abut against the inner wall of the winding drum.

[0007] Preferably, the positioning shaft has a hollow structure, and the elastic connecting member includes: two transmission connecting rods, which are arranged in parallel between the abutment arm and the positioning shaft, and are respectively hinged to the abutment arm and the positioning shaft at both ends; a sliding block, which is slidably disposed in the positioning shaft along the axial direction; a spring, which is disposed in the positioning shaft and connected to the sliding block; and a guide connecting rod, which is respectively hinged to the sliding block and one of the transmission connecting rods at both ends, forming a linkage mechanism.

[0008] Preferably, the rotating seat is provided with a connecting channel, one end of the positioning shaft extends into the connecting channel, and the elastic connector further includes a connecting rod, which coaxially passes through the connecting channel and one end is fixedly connected to the sliding block; an adjusting cylinder, which is coaxially disposed at the other end of the connecting channel; and a fixing ring, which is coaxially fixedly disposed on the connecting rod, and a spring is sleeved on the connecting rod and located between the adjusting cylinder and the fixing ring.

[0009] Preferably, the connecting channel of the adjusting cylinder is threaded.

[0010] Preferably, the inner abutment assembly further includes a rubber strip disposed on the outside of the abutment arm.

[0011] Preferably, the outer side of the rubber strip is provided with grinding teeth at equal intervals.

[0012] Preferably, it also includes an auxiliary unloading mechanism, which includes a slide cylinder, disposed on the back side of the rotary table loading and unloading station; and a finger cylinder, disposed at the working end of the slide cylinder. One end of the connecting rod at the loading and unloading station extends to the clamping port of the finger cylinder. When the finger cylinder clamps the connecting rod and moves outward, the abutment arm disengages from the winding drum radially.

[0013] Preferably, the rotating seat has a conical structure, with its diameter gradually decreasing from the rotary disk towards the positioning shaft, forming a mating end face that matches the end of the winding drum.

[0014] The advantages of this application compared to the prior art are:

[0015] This application integrates the winding station and the loading / unloading station onto a rotary table and equips them with interchangeable positioning fixtures, enabling continuous operation of the winding process and significantly improving production efficiency. In this design, after the winding station completes the wire winding, the rotary table rotates 180°, exchanging the positions of the empty winding spool and the finished winding spool. At this point, the wire remains in a bridging state, and the rotating abutment joint automatically presses and positions the new winding spool while simultaneously maintaining wire tension. This process avoids the cumbersome steps of disassembling the finished winding spool and installing the new spool required in traditional automatic winding machines, thus preventing intermittent operation and reducing downtime.

[0016] Furthermore, the wire-cutting mechanism quickly cuts off the connecting wire between the two stations, ensuring that new winding operations can begin immediately. Meanwhile, finished winding bobbins at the loading and unloading stations can be unloaded simultaneously, and new bobbins can be clamped. This design not only significantly improves the automation level of the workstation but also solves the production gap problem between the winding and loading / unloading stations, ensuring a continuous production process and avoiding downtime caused by bobbin changes and disassembly in traditional operations. Ultimately, this system optimizes the production process, improves the efficiency of the automated production line, reduces labor costs, and increases output. Attached Figure Description

[0028] 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.

[0029] like Figures 1-5 as well as Figure 7As shown, a winding machine with a rotating and changing function for the winding drum includes a rotary table 1, which has loading / unloading stations and winding stations spaced circumferentially; a rotary positioning assembly, including two positioning fixtures 2 symmetrically arranged at the loading / unloading stations and the winding stations, wherein the winding station is provided with an abutting rotating head that is driven to connect with the winding drum 7, and the positioning fixture 2 has a clamping part that fixes the inner wall of the winding drum 7; the rotary table 1 rotates to drive the two positioning fixtures 2 to interchange positions; and a loading / unloading system, including a robotic arm 5 set at the loading / unloading station for executing finished product loading / unloading. The combined action of unloading the winding drum 7 and loading the new winding drum 7; the cutting mechanism 6, whose blade is located on the vertical line connecting the loading / unloading station and the winding station; the working end face of the positioning fixture 2 is provided with a flange that can dock with the end of the winding drum 7. When the positioning fixture 2 at the winding station rotates to the loading / unloading station, the wire is crossed between the flange and the end of the winding drum 7. When the abutting rotating head abuts against the other end of the winding drum 7, the flange and the end of the winding drum 7 clamp the wire and trigger the cutting mechanism 6 to cut the wire.

[0030] The equipment centers on a rotary table 1, with loading / unloading stations and winding stations spaced circumferentially. Rotational motion facilitates station switching and production rhythm coordination. The winding machine features two symmetrically positioned fixtures 2 at the winding and loading / unloading stations, used to secure the winding drum 7 and ensure its stability during winding and changing processes. Each fixture 2 is equipped with a clamping part to secure the inner wall of the winding drum 7 and a flange structure that approaches the end of the winding drum 7 to provide auxiliary clamping before wire cutting.

[0031] After winding is completed at the winding station, the rotary table 1 rotates 180°, allowing the two stations to interchange. The finished winding spool 7 rotates to the loading / unloading station. While the empty winding spool 7 enters the winding station, the wire remains in a bridging state. The contact rotating head at the winding station automatically aligns with the new winding spool 7 and presses it into position, while maintaining the wire tension to prevent slack. At this time, the wire lies across the end of the new spool and the flange of the positioning fixture 2. After the rotating head completes the pressing, the flange and the spool clamp the wire, triggering the cutting mechanism 6 to precisely cut the wire along the perpendicular bisector of the line connecting the two stations. After the new spool is connected, it enters the next round of winding operations, while the finished winding spool 7 at the loading / unloading station is unloaded simultaneously. The new winding spool 7 can also be clamped and positioned by the robot arm 5 at this station, ready for the next round of operations.

[0032] This structure significantly improves the continuity and automation of the winding process. The rotation mechanism of the rotary table 1 solves the interruption problem that occurs when changing the winding spool 7 in traditional winding machines, avoiding production interruptions and delays caused by manual operation. The introduction of the robotic arm 5 enables automatic unloading of finished winding spools 7 and automatic loading of new spools, reducing manual intervention, improving operational accuracy, and lowering errors or safety hazards caused by human factors. The wire remains taut during station changes, making the winding process more stable and eliminating winding defects caused by loose wire. The wire cutting mechanism 6 is rationally positioned, and the cutting process is rapid and accurate, ensuring neat wire separation and further guaranteeing process continuity and product consistency.

[0033] The rotary table 1 is driven by a rotary motor, enabling it to rotate precisely to a predetermined workstation position. The control system of the rotary motor precisely adjusts the speed and direction of the rotary table 1 to achieve rapid switching between workstations. When the rotary table 1 rotates to the set position, the winding workstation and the loading / unloading workstation are switched, automatically completing the winding operation.

[0034] At the winding station, the rotating head is driven by a rotary motor to ensure continuous movement and smooth winding during the process. The rotary motor adjusts its rotation speed as needed to precisely control the tension and speed of the winding.

[0035] The ball screw slide table ensures a tighter and more stable connection between the rotary motor and the rotary joint, enabling precise axial movement. This design allows the rotary joint to precisely align with the other end of the winding drum 7 during the wire tensioning process at the winding station.

[0036] like Figure 6 , Figures 7-10 As shown, the positioning fixture 2 also includes a rotating seat 21, which is rotatably mounted on the rotary table 1, with one end face forming the flange; a positioning shaft 22, which is coaxially fixedly connected to the rotating seat 21; and an inner abutment component 23, which is distributed circumferentially along the positioning shaft 22 and is used to radially abut against the inner wall of the winding drum 7.

[0037] The rotating seat 21 is rotatably mounted on the rotary table 1 via a bearing, and one end face of the seat forms a flange that can be inserted into the port of the winding drum 7. The outer diameter of the flange is adapted to the inner diameter of the port of the winding drum 7. When the winding drum 7 is installed, the flange is inserted into the port of the winding drum 7, thereby restricting the circumferential rotation of the winding drum 7.

[0038] The positioning shaft 22 is coaxially and fixedly connected to the rotating seat 21, and their axes coincide. The positioning shaft 22 extends along the axial direction of the rotating seat 21. When the winding drum 7 is installed in conjunction with the rotating seat 21 through the flange, the positioning shaft 22 passes into the center hole of the winding drum 7, providing axial support for the winding drum 7.

[0039] The inner abutment assembly 23 is distributed circumferentially along the positioning shaft 22 and includes an abutment block and a drive structure. The abutment block is radially movable along the positioning shaft 22, and the drive structure is connected to the abutment block. When the winding drum 7 is installed in place, the drive structure drives the abutment block to move radially outward until the abutment block abuts against the inner wall of the winding drum 7, thereby achieving radial fixation of the winding drum 7.

[0040] When the rotary table 1 rotates 180° to interchange the positions of the winding drum 7, the rotating seat 21 rotates synchronously with the rotary table 1, and the wire wound on the finished winding drum 7 will be connected across the positioning shaft 22 and located between the flange and the end of the winding drum 7.

[0041] The inner abutment component 23 maintains radial contact with the inner wall of the winding drum 7, ensuring the stability of the winding drum 7 during rotation. When the rotating abutment joint 3 presses against the new winding drum 7, the end of the winding drum 7 mates with the flange and clamps the wire, facilitating the winding of the wire onto the new winding drum 7. The flange and the rotating abutment joint 3 form positioning from both ends of the winding drum 7, and the inner abutment component 23 continues to provide radial contact force, ensuring that the tension of the wire is not affected.

[0042] like Figure 6 , Figures 7-10 As shown, the inner abutting component 23 includes an abutting arm 231, which is arranged parallel to the positioning shaft 22; and an elastic connector, which is disposed between the abutting arm 231 and the positioning shaft 22, for making the abutting arm 231 elastically abut against the inner wall of the winding drum 7.

[0043] The abutment arm 231 is elongated, with its length parallel to the axial direction of the positioning shaft 22. There are at least two abutment arms 231, which are evenly distributed around the circumference of the positioning shaft 22. One end of the abutment arm 231 is hinged to the positioning shaft 22, and the axis of the hinge axis is perpendicular to the axis of the positioning shaft 22, allowing the abutment arm 231 to rotate radially around the hinge axis along the positioning shaft 22. The other end of the abutment arm 231 is a free end, and the outer wall surface of the free end can be set as an arc-shaped surface adapted to the inner wall of the winding drum 7.

[0044] One end of the elastic connector is connected to the middle of the abutment arm 231, and the other end is connected to the outer wall of the positioning shaft 22. In its natural state, the elastic connector is in a pushed-out state, and its thrust drives the free end of the abutment arm 231 to rotate outward along the radial direction of the positioning shaft 22, so that the arc-shaped surface of the abutment arm 231 abuts against the inner wall of the winding drum 7.

[0045] When the winding drum 7 is fitted outside the rotating seat 21 and the positioning shaft 22, the inner wall of the winding drum 7 presses against the free end of the abutment arm 231, causing the abutment arm 231 to rotate against the thrust of the elastic connector towards the axis of the positioning shaft 22 until the winding drum 7 is installed in place. At this time, the thrust of the elastic connector continues to act on the abutment arm 231, so that the arc-shaped surface of the abutment arm 231 always remains in contact with the inner wall of the winding drum 7. When the flange is not mated with the winding drum 7, the abutment force between the abutment arm 231 and the inner wall of the winding drum 7 can limit the axial movement of the winding drum 7 along the positioning shaft 22, preventing the winding drum 7 from detaching from the inner abutment assembly 23.

[0046] like Figure 6 , Figures 7-10 As shown, the positioning shaft 22 has a hollow structure, and the elastic connecting parts include: two transmission connecting rods 2321, which are arranged in parallel between the abutment arm 231 and the positioning shaft 22, and are hinged to the abutment arm 231 and the positioning shaft 22 at both ends respectively; a sliding block 2322, which is slidably disposed in the positioning shaft 22 along the axial direction; a spring 2323, which is disposed in the positioning shaft 22 and connected to the sliding block 2322; and a guide connecting rod 2324, which is hinged to the sliding block 2322 and one of the transmission connecting rods 2321 at both ends respectively, forming a linkage mechanism.

[0047] Two transmission links 2321 are arranged in parallel between the abutment arm 231 and the positioning shaft 22. One end of each link is hinged to the abutment arm 231, and the other end is hinged to the outer wall of the positioning shaft 22. The two transmission links 2321, together with the abutment arm 231 and the positioning shaft 22, form a parallelogram structure. A sliding block 2322 is slidably disposed within the hollow cavity of the positioning shaft 22 along the axial direction of the shaft. The outer wall of the sliding block 2322 is clearance-fitted with the inner wall of the positioning shaft 22. A spring 2323 is disposed within the hollow cavity of the positioning shaft 22. One end of the spring 2323 is fixedly connected to the inner wall of the positioning shaft 22, and the other end is connected to the side of the sliding block 2322 away from the fixed end of the spring 2323. One end of the guide link 2324 is hinged to the sliding block 2322, and the other end is hinged to the middle of one of the transmission links 2321, forming a linkage mechanism.

[0048] When the winding drum 7 is fitted outside the rotating seat 21 and the positioning shaft 22, the inner wall of the winding drum 7 presses against the free end of the abutment arm 231. The abutment arm 231 rotates around its hinge axis with the positioning shaft 22 in the direction of the positioning shaft 22's axis, driving the two transmission connecting rods 2321 to rotate synchronously. This, in turn, pushes the sliding block 2322 along the axial direction of the positioning shaft 22 towards the fixed end of the spring 2323 through the guide connecting rod 2324, compressing the spring 2323. After the winding drum 7 is installed in place, the elastic force of the spring 2323 is transmitted to the abutment arm 231 through the sliding block 2322, the guide connecting rod 2324, and the transmission connecting rod 2321, ensuring that the arc-shaped surface of the abutment arm 231 always remains in contact with the inner wall of the winding drum 7. When the flange is not mated with the winding drum 7, the contact force between the abutting arm 231 and the inner wall of the winding drum 7 can restrict the axial movement of the winding drum 7 along the positioning shaft 22, preventing the winding drum 7 from detaching from the inner abutting assembly 23.

[0049] like Figure 6 , Figures 7-10 As shown, the rotating seat 21 is provided with a connecting channel, one end of the positioning shaft 22 extends into the connecting channel, and the elastic connector also includes a connecting rod 2325, which coaxially passes through the connecting channel and one end of which is fixedly connected to the sliding block 2322; an adjusting cylinder 2326, which is coaxially disposed at the other end of the connecting channel; a fixing ring 2327, which is coaxially fixedly disposed on the connecting rod 2325; and a spring 2323 sleeved on the connecting rod 2325 and located between the adjusting cylinder 2326 and the fixing ring 2327.

[0050] When the winding drum 7 is fitted outside the rotating seat 21 and the positioning shaft 22, the inner wall of the winding drum 7 presses against the free end of the abutment arm 231. The abutment arm 231 rotates around its hinge axis with the positioning shaft 22 in the direction of the axis of the positioning shaft 22, driving the two transmission connecting rods 2321 to rotate synchronously. In turn, the guide connecting rod 2324 pushes the sliding block 2322 to move along the axis of the positioning shaft 22 towards the rotating seat 21. The sliding block 2322 drives the connecting rod 2325 to move synchronously, causing the fixing ring 2327 to compress the spring 2323. After the winding drum 7 is installed in place, the elastic force of the spring 2323 is transmitted to the abutment arm 231 in sequence through the fixing ring 2327, the connecting rod 2325, the sliding block 2322, the guide connecting rod 2324 and the transmission connecting rod 2321, so that the arc-shaped surface of the abutment arm 231 always remains in contact with the inner wall of the winding drum 7.

[0051] like Figure 6 , Figures 7-10 As shown, the connecting channel of the adjusting cylinder 2326 is threaded.

[0052] The adjusting cylinder 2326 can be moved axially along the connecting channel to change the initial compression of the spring 2323, thereby adjusting the abutting force of the abutting arm 231 against the inner wall of the winding drum 7. When the flange is not mated with the winding drum 7, the abutting force between the abutting arm 231 and the inner wall of the winding drum 7 can limit the axial movement of the winding drum 7 along the positioning shaft 22, preventing the winding drum 7 from detaching from the inner abutting assembly 23.

[0053] like Figure 6 , Figures 7-10 As shown, the inner abutment component 23 also includes a rubber strip 233, which is disposed on the outside of the abutment arm 231.

[0054] When the winding drum 7 is sleeved outside the rotating seat 21 and the positioning shaft 22, the inner wall of the winding drum 7 squeezes the part of the rubber strip 233 that protrudes from the arc surface of the abutting arm 231. The rubber strip 233 elastically deforms and fills the gap between itself and the inner wall of the winding drum 7. Under the action of the force transmitted by the rubber strip 233, the abutting arm 231 rotates around the hinge axis with the positioning shaft 22 in the direction of the positioning shaft 22 axis, driving the two transmission connecting rods 2321 to rotate synchronously. Through the guide connecting rod 2324, the sliding block 2322 is pushed to move along the positioning shaft 22 axis towards the rotating seat 21. The sliding block 2322 drives the connecting rod 2325 to move synchronously, so that the fixing ring 2327 compresses the spring 2323.

[0055] After the winding drum 7 is installed in place, the elastic force of the spring 2323 is transmitted to the abutment arm 231 through the fixing ring 2327, connecting rod 2325, sliding block 2322, guide connecting rod 2324 and transmission connecting rod 2321 in sequence, so that the rubber strip 233 always maintains surface contact with the inner wall of the winding drum 7.

[0056] The friction and contact force between the rubber strip 233 and the inner wall of the winding drum 7 work together to restrict the axial movement of the winding drum 7 along the positioning shaft 22 and prevent the winding drum 7 from detaching from the inner contact assembly 23.

[0057] like Figure 6 , Figures 7-10 As shown, the outer side of the rubber strip 233 is provided with grinding teeth 2331 at equal intervals.

[0058] The grinding teeth 2331 are used to prevent the winding drum 7 from detaching from the rubber strip 233 along the axial direction of the positioning shaft 22.

[0059] like Figure 4 As shown, it also includes an auxiliary unloading mechanism, which includes a slide cylinder 81, which is located on the back side of the loading and unloading station of the rotary table 1; and a finger cylinder 82, which is located at the working end of the slide cylinder 81. One end of the connecting rod 2325 at the loading and unloading station extends to the clamping port of the finger cylinder 82. When the finger cylinder 82 clamps the connecting rod 2325 and moves it outward, the abutment arm 231 disengages from the winding drum 7 radially.

[0060] When it is necessary to detach the winding drum 7 from the positioning fixture 2, the finger cylinder 82 is activated, and its clamping port closes to clamp one end of the connecting rod 2325 extending to the clamping port. Then, the working end of the slide cylinder 81 moves outward, driving the finger cylinder 82 and the clamped connecting rod 2325 to move outward synchronously. The connecting rod 2325 drives the sliding block 2322 to move along the positioning shaft 22 towards the rotating seat 21. The sliding block 2322 pulls the transmission connecting rod 2321 to rotate through the guide connecting rod 2324, causing the abutment arm 231 to rotate around the hinge axis with the positioning shaft 22 in the direction of the positioning shaft 22 axis. The rubber strip 233 and the grinding teeth 2331 move synchronously with the abutment arm 231, detaching from the inner wall of the winding drum 7 radially. At this time, the winding drum 7 can be quickly detached from the positioning fixture 2. After unloading is completed, the working end of the slide cylinder 81 is reset, the gripping port of the finger cylinder 82 is opened, and the spring 2323 pushes the fixing ring 2327, the connecting rod 2325 and the sliding block 2322 to reset under its own elastic force, and the abutment arm 231 is simultaneously reset to the initial position.

[0061] like Figure 6 , Figures 7-10 As shown, the rotating seat 21 has a conical structure, and its diameter gradually decreases from the rotary disk 1 towards the positioning shaft 22, forming a mating end face that is compatible with the port of the winding drum 7.

[0062] The rotating seat 21 has a conical structure, and its outer wall surface is a conical surface. The diameter of the conical surface gradually decreases axially from the side of the rotary disk 1 to the side of the positioning shaft 22. The end of the rotating seat 21 away from the rotary disk 1 forms an annular mating end face. The mating end face is perpendicular to the axis of the rotating seat 21, and the outer diameter of the mating end face is adapted to the inner diameter of the winding drum 7 port. The winding drum 7 port can be sleeved on the mating end face to achieve axial positioning.

[0063] 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.
