[0002] Aramid core-spun yarn is a special composite yarn with aramid fiber as the outer layer and high-performance filament as the core. With its excellent properties such as high strength, wear resistance, high temperature resistance, flame retardancy and impact resistance, it is widely used in high-end fields such as protective clothing, industrial conveyor belts, aerospace, fire-fighting equipment, and special cables. It is an indispensable basic textile material for modern industry and security industry. Currently, in the production process of aramid core-spun yarn, the core yarn conveying process still relies on manual carrying for replacement. Under the traditional production model, the overall operation mode is extensive and has multiple drawbacks. On the one hand, manual handling is labor-intensive and costly. Moreover, the textile workshop has many workstations that are scattered and the equipment is long.

[0014] The multi-station synchronous aramid core-spun yarn suspension conveying mechanism proposed in this invention has the following advantages: 1. The overall layout adopts a ceiling-mounted design, with all mechanisms suspended from the workshop ceiling, without occupying the ground production area. It can be directly adapted to the existing workstation layout of textile workshops without requiring large-scale modifications to the ground production line. The track and support structure adopt a modular splicing design. The number of sections of the second track and series pipe can be flexibly increased or decreased through connecting rods. The line length and layout can be freely adjusted according to the number of workshop workstations and the conveying distance, adapting to different scale production scenarios. The on-site installation and expansion costs are low.

[0015] 2. Relying on the first electric slide rail and the movable lifting frame of the line changing component, the precise docking and reversal of the stacking station track and the main conveyor track can be completed automatically. The drive structure can flexibly switch between different workstation lines without manual intervention, opening up the conveying path between multiple workstations. With the help of multiple sets of pickup components arranged at equal intervals at the bottom of the drive box, multiple rolls of core yarn can be carried simultaneously at one time, and the material replenishment of multiple production workstations can be completed at one time. This effectively solves the problem of scattered workstations in the workshop and the time-consuming manual back-and-forth transfer, and avoids the disconnection of process and the congestion of the production line.

[0016] 3. The stacking platform is equipped with detachable limit rods, which can flexibly adjust the installation position and spacing according to the specifications and dimensions of the core yarn rolls, forming a separation and positioning for the core yarn rolls. This effectively avoids material displacement and scattering during the stacking process, providing a regular and stable material station for automated picking. Combined with the multi-directional displacement adjustment of the cross-shaped slide rail on the top of the drive structure, the lifting adjustment of the hydraulic cylinder, and the real-time positioning of the liftable visual monitoring component, the precise alignment of the picking structure and the core yarn roll can be achieved, resulting in high accuracy in material picking and reducing the risk of material falling.

[0017] 4. The drive structure adopts two sets of symmetrical drive units driving in opposite directions. Each set of drive units achieves synchronous transmission of dual drive rollers through pulleys arranged in an isosceles triangle and drive belt. The whole machine moves along the track by friction, and the overall force is balanced. At the same time, it integrates remote control and voice control modes. Operators can plan the conveying path remotely through the remote control or complete the operation locally through voice commands. With the real-time visual monitoring function, the status of the workstation and the material status can be monitored simultaneously. The degree of automation is high, which effectively reduces the labor intensity and operation difficulty of personnel.

[0018] 5. The pickup assembly adopts an adjustable-spacing elastic locking structure. Through the sliding cooperation between the moving arm and the adjusting groove, the locking spacing can be flexibly adjusted to adapt to core yarn rolls with different inner diameter specifications. Relying on the elastic clamping structure composed of springs and top caps, the core yarn rolls in the set are flexibly locked, which can not only ensure the stability of the conveying process, but also avoid damage to the yarn surface by hard clamping and squeezing. In addition, the pickup assembly adopts a detachable installation form with threaded connection, and the quantity can be flexibly increased or decreased according to the conveying needs.

[0019] In summary, this invention achieves fully automated operation of aramid core-spun yarn from material storage and track changing to automatic transfer, significantly reducing the labor cost and intensity of manual handling, improving the connection efficiency and conveying continuity of multi-station production, while having a high degree of modularity, wide applicability to various scenarios, and low operation and maintenance costs.

The bottom sidewalls of track 112 are all perforated with first connecting grooves 41. One end of a pair of first lifting rods 113 is fixedly installed on the lower wall of one end of the first track 112. One end of a pair of stacking platforms 114 is respectively installed on the other end of the first lifting rods 113, and the stacking platforms 114 are located below the first track 112. Several threaded holes are symmetrically arranged on each stacking platform 114.

[0031] As a further embodiment of the present invention, the drive unit 21 includes a pair of roller frames 211, a pair of drive rollers 212, a motor 213, three pulleys 214, and a drive belt 215. The pair of roller frames 211 are both F-shaped structures, with one end of each frame fixedly mounted on the lower walls of the left and right ends of the drive housing 20, and located in front of the slide groove 51. The pair of drive rollers 212 are movably mounted on the roller frames 211 via roller shafts, with the top ends of the roller shafts corresponding to the drive openings 54. The motor 213 is fixedly mounted on the lower wall of the partition 52, and located in front of the roller frames 211. The motor 213 and the pair of roller frames 211 are arranged in an isosceles triangle. The three pulleys 214 are respectively fixedly mounted on the roller shafts of the pair of drive rollers 212 and on the drive end of the motor 213. The drive belt 215 is respectively... The active set is mounted on three pulleys 214, and the drive belt 215 is extended in a triangular shape through the pulleys 214. The roller frame 211 is fixed to the lower walls of the left and right ends of the drive box 20 and is located in front of the slide groove 51. The drive roller 212 is mounted on the roller frame 211 by means of the roller shaft. The upper end of the roller shaft corresponds to the drive port 54 on the side wall of the drive box 20, ensuring that the drive roller 212 can effectively contact the track. The motor 213 is fixed to the lower wall of the partition 52 inside the drive box 20. The whole is arranged in an isosceles triangle with the two sets of roller frames 211. The three pulleys 214 are respectively mounted on the roller shafts of the two drive rollers 212 and the drive end of the motor 213. The drive belt 215 is then wrapped around the outside of the three pulleys 214, so that the drive belt 215 is in a triangular tensioned state. When the equipment is running, the motor 213 outputs torque to drive the corresponding pulley 214 to rotate. The drive belt 215 synchronously drives the other two pulleys 214 and two drive rollers 212 to rotate together. The rotating drive rollers 212 are in close contact with the side wall of the track to generate friction. Relying on this friction, the drive box 20 is driven to move forward and backward along the first track 112 and the second track 122, thereby realizing the walking and conveying of the whole machine. The drive box 20 can move along the second track 122 by rotating the drive rollers 212 in the drive unit 21, and the drive box 20 can move onto the first track 112.

[0032] More specifically, the transmission structure of the triangularly arranged pulleys 214 has a simple transmission path, good tension effect, stable power transmission and is not easy to slip; the isosceles triangular layout makes the overall force uniform, and the two sets of symmetrically arranged drive units 21 further improve the stability of walking; the F-shaped roller frame 211 has high structural strength and can stably support the operation of the drive roller 212. The whole set of components is easy to assemble, has a low failure rate and is easy to maintain. It can continuously provide reliable power for the movement of the device and effectively ensure that the equipment can run smoothly and reciprocatingly on the track for a long time.

[0033] As a further embodiment of the present invention, the pickup structure 3 includes a pickup frame 31, a third electric slide rail 32, a clamping arm 33, and several pickup components 34. The pickup frame 31 is L-shaped, with one end fixedly mounted on the telescopic end of the hydraulic cylinder body 24 and located on the left side of the drive box 20.

The clamping arm 33 can correspond to the limiting rod 115. Several pickup components 34 are detachably mounted on the lower walls of the front and rear ends of the drive box 20 and are arranged at equal intervals. The pickup frame 31 is fixed to the hydraulic cylinder body 24 at one end. The telescopic end of 4 is arranged on the left side of the drive box 20, and its other end extends to the working area below the drive box 20; the third electric slide rail 32 is installed on the pickup frame 31, and the clamping arm 33 is fixed on the third electric slide rail 32 and parallel and symmetrical to the vertical section of the pickup frame 31. The third electric slide rail 32 can drive the clamping arm 33 to move linearly, so that the clamping arm 33 and the pickup frame 31 cooperate to complete the opening and closing clamping action, accurately aligning with the limit rod 115 on the stacking platform 114 and the core yarn roll, realizing the clamping and detachment of the core yarn roll from the limit rod 115; multiple sets of pickup components 34 are detachably installed on the lower walls of the front and rear ends of the drive box 20 in an equidistant manner. After the clamping arm 33 removes the core yarn roll from the limit rod 115, the core yarn roll can be transferred and placed on the pickup component 34, which completes the bearing and fixing, and then follows the drive structure 2 to complete the transfer operation.

[0034] More specifically, by integrating clamping and carrying functions, the hydraulic cylinder finally lifts the core yarn rolls, and the third electric slide rail 32 enables multi-directional movement adjustment, ensuring precise clamping and positioning, and stably completing the picking and placing of core yarn rolls. The picking component 34 adopts a detachable and equidistant arrangement, which is flexible in disassembly and assembly and can carry multiple core yarn rolls at the same time, realizing the synchronous conveying of multiple pieces, effectively improving the conveying efficiency. The overall structure works well together and the actions are smooth, adapting to the picking conditions of the stacking platform 114 limit rod 115, greatly improving practicality and work efficiency.

[0035] As a further embodiment of the present invention, the pickup assembly 34 includes an adjusting frame 341, a mounting nut 342, a fixed shaft rod 343, a top cap 344, a spring 345, a moving arm 346, and a third bolt 347. The adjusting frame 341 is L-shaped, and a screw is provided in the middle of one end of the adjusting frame 341. One end of the adjusting frame 341 is screwed to the lower wall of the drive box 20 via the screw, and an adjusting groove 6 is provided in the middle of the other end of the adjusting frame 341. The mounting nut 342 is screwed onto the screw at one end of the adjusting frame 341, and the mounting nut 342 fits against the lower wall of the drive box 20 for stable installation. One end of the fixed shaft rod 343 is fixedly disposed on the lower wall of the other end of the adjusting frame 341, and the fixed shaft rod 345 is fixed to the lower wall of the other end of the adjusting frame 341. The other end of the shaft 343 is provided with a telescopic cavity. The top cap 344 is movably fitted into the telescopic cavity of the fixed shaft 343, and one end of the top cap 344 movably passes through the right side wall of the fixed shaft 343. The top cap 344 is a convex round rod structure. One end of the spring 345 is fixedly set on the left side wall of the telescopic cavity of the fixed shaft 343, and the other end of the spring 345 is fixedly connected to the top cap 344. The movable arm 346 has a Z-shaped structure. One end of the movable arm 346 is movably set on the adjusting bracket 341, and the other end of the movable arm 346 can fit against the other end of the fixed shaft 343. One end of the third bolt 347 movably passes through the adjusting groove 6, and the third bolt 347 is screwed onto the movable arm 346. The end is used for fixing; the adjusting bracket 341 is screwed onto the lower wall of the drive box 20 by the end screw, and then the mounting nut 342 is tightened on the screw and attached to the bottom surface of the drive box 20 to lock and fix the adjusting bracket 341 to prevent loosening and displacement during operation; the adjusting bracket 341 has an adjusting groove 6 at the bottom, and the Z-shaped moving arm 346 is movably assembled on the adjusting bracket 341. The third bolt 347 passes through the adjusting groove 6 and is screwed into the moving arm 346. Loosening the third bolt 347 allows the moving arm 346 to slide along the adjusting groove 6, thereby adjusting the distance between the moving arm 346 and the fixed shaft rod 343. After adjusting to the appropriate position, tighten the third bolt 347 to complete the locking; the fixed shaft rod 34 3. Fixed at the lower end of the adjusting frame 341, which has a telescopic cavity inside. A convex cylindrical top cap 344 is movably fitted inside the telescopic cavity. The outer end of the top cap 344 extends out of the side wall of the fixed shaft rod 343. A spring 345 is connected between the left side wall inside the telescopic cavity and the top cap 344. When the core yarn roll is put into the fixed shaft rod 343 and the moving arm 346, the inner wall of the core yarn roll squeezes the top cap 344, causing it to retract into the telescopic cavity. The spring 345 is compressed. After the core yarn roll is fully put in, the spring 345 rebounds and pushes the top cap 344 outward. The top cap 344 is used to lock the core yarn roll in place, and together with the moving arm 346, it completes the stable support and fixation of the core yarn roll.

[0036] More specifically, the device features flexible adjustment of the clamping spacing based on the inner diameter of the core yarn rolls, offering strong versatility. The elastic locking structure formed by spring 345 and top cap 344 ensures convenient and secure loading and unloading of materials, preventing the core yarn rolls from slipping or shaking during transport. The device is easy to assemble, disassemble, and adjust, with a compact and durable structure. Multiple components working together can simultaneously transport multiple core yarns, effectively improving overall transport efficiency. The elastic contact method prevents hard compression from damaging the yarn, ensuring product quality.

[0037] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0038] The device consists of three main modules: hoisting structure 1, drive structure 2, and picking structure 3. All of them are hoisted on the ceiling of the workshop. Relying on the coordinated operation of each component, it completes the entire process of stacking, track reversing, moving and shifting, and picking and transferring aramid core-spun yarn. The basic support of the entire device is the hoisting structure 1, which is divided into two main parts: the material stacking assembly 11 and the line changing assembly 12. In the material stacking assembly 11, two sets of concave first hangers 111 are symmetrically fixed to the ceiling, and two parallel first tracks 112 are mounted below. The bottom side wall of the first track 112 is provided with a first docking groove 41 for track docking. The first hanger 113 is vertically connected to the lower wall of the first track 112, and the bottom end of the material stacking platform 114 is suspended as the core yarn stacking station. Multiple limiting rods 115 can be detachably screwed onto the material stacking platform 114. The core yarn rolls are sequentially sleeved on the limiting rods 115 to complete the neat storage. The line-changing assembly 12 and the stacking assembly 11 are connected to achieve track reversal. The second hanger 121, which has the same structure as the first hanger 111, is fixed to the ceiling and aligned with the first hanger 111. Multiple sections of the second track 122 with the same specifications as the first track 112 are arranged in sequence. The ends of adjacent second tracks 122 are connected in series by connecting rods 123. The first bolts 124 are then tightened to tighten the connecting rods 123, thus achieving track splicing and locking. A Z-shaped third hanger 125 is fixed to the lower side of the right second track 122, with a second connecting groove 42 at its end. Multiple series pipes 126 are also connected in series by connecting rods 123 and first bolts 124. The two ends of the series pipes 126 are respectively connected to the stacking platform 114 and the third hanger 125, which serve as overall support. A support 127 is fixed on the series pipe 126 between the first track 112 and the second track 122. A first electric slide rail 128 is horizontally installed on the support 127. A lifting frame 129 is fixed on the electric slide table of the first electric slide rail 128. A second track 122 is installed at both ends of the lifting frame 129. During operation, the first electric slide rail 128 drives the lifting frame 129 to move back and forth, so that the second track 122 on the lifting frame 129 is respectively connected to the second track 122 on the first track 112 and the second hanger 121, thus completing the line switching. Drive structure 2 is the core of the device's movement, control, and adjustment. The rectangular drive box 20 is slidably mounted on the first track 112 and the second track 122 via the bottom slide groove 51. The box has a partition 52 to achieve spatial division, and drive ports 54 are opened on the left and right side walls. Two sets of drive units 21 are symmetrically installed on the front and rear sides of the slide groove 51. Each set of drive units 21 includes two F-shaped roller frames 211, drive rollers 212, motors 213, three pulleys 214, and a drive belt 215. The roller frames 211 are fixed to the lower wall of the drive box 20, and the drive rollers 212 are mounted on the roller frames 211 via roller shafts. The top of the upper roller shaft corresponds to the drive port 54. The motor 213 is fixed below the partition plate 52. The motor 213 and the two sets of roller frames 211 are arranged in an isosceles triangle. Three pulleys 214 are respectively installed on the output end of the motor 213 and the roller shaft of the two drive rollers 212. The drive belt 215 is in a triangular tensioned sleeve on the outside of the pulleys 214. When the motor 213 runs, it drives the drive rollers 212 to rotate through the pulleys 214 and the drive belt 215. The drive rollers 212 generate power by friction with the side wall of the track. The two sets of drive units 21 rotate in opposite directions, driving the drive box 20 to move smoothly along the track. A cross-shaped slide rail 22 is fixed to the top of the drive box 20. The cylinder arm 23 is mounted on the cross-shaped slide rail 22, enabling forward and backward and left and right movement. The hydraulic cylinder body 24 is fixed through the cylinder arm 23 and adjusts its position synchronously with the cylinder arm 23. The controller body 25 is embedded in the front side wall of the drive box 20, and a sound receiver 26 is installed on the right side wall. The external remote control body 27 can communicate with the controller body 25 to achieve integrated remote control and voice control. A camera frame 28 is movably installed on the rear side wall of the drive box 20. The camera frame 28 has a lifting groove 53 in the middle. The second bolt 29 passes through the lifting groove 53 and is screwed onto the drive box 20. Loosening the second bolt 29 can adjust the height of the camera frame 28 up and down. Locking it completes the positioning. A camera 291 is installed at the end of the camera frame 28 to collect on-site images in real time, identify personnel and workstation positions, and cooperate with the control system to complete positioning, transportation and safety monitoring, or detect the core yarn status of the equipment and stop it directly at the broken yarn location. The picking structure 3 is a material gripping and carrying actuator. One end of the L-shaped picking frame 31 is fixed to the telescopic end of the hydraulic cylinder body 24, and the whole is located on the left side of the drive box 20. The other end extends to the working area below the drive box 20. A third electric slide rail 32 is installed on the picking frame 31. The clamping arm 33 is fixed on the third electric slide rail 32 and is parallel and symmetrical to the picking frame 31. The third electric slide rail 32 drives the clamping arm 33 to move, and cooperates with the picking frame 31 to form a clamping structure, accurately aligning with the limiting rod 115 on the stacking platform 114, and clamping and detaching the core yarn roll from the limiting rod 115. Multiple pickup components 34 are equidistantly and detachably installed on the lower walls of the front and rear ends of the drive housing 20. Each pickup component 34 consists of an adjusting frame 341, a mounting nut 342, a fixed shaft rod 343, a top cap 344, a spring 345, a moving arm 346, and a third bolt 347. The L-shaped adjusting frame 341 is screwed to the lower wall of the drive housing 20 by an end screw, and is locked in place by tightening the mounting nut 342. An adjusting groove 6 is provided at the lower part of the adjusting frame 341, and the Z-shaped moving arm 346 is movably installed on the adjusting frame 341. The third bolt... 347 passes through the adjustment slot 6 and screws into the movable arm 346. Loosening the third bolt 347 allows the movable arm 346 to slide, adjusting its distance from the fixed shaft rod 343 to accommodate core yarn rolls with different inner diameters. After adjustment, tighten the third bolt 347 to lock it in place. The fixed shaft rod 343 is fixed at the lower end of the adjustment frame 341 and has a telescopic cavity inside. The top cap 344 with a convex round rod structure is movably embedded in the telescopic cavity. The outer end of the top cap 344 extends out of the fixed shaft rod 343. The two ends of the spring 345 inside the telescopic cavity are connected to the inner wall of the telescopic cavity and the top cap 344, respectively. After the clamping arm 33 removes the core yarn roll, the hydraulic cylinder body 24 and the cross-shaped slide rail 22 work together to adjust the position and put the core yarn roll onto the fixed shaft rod 343 and the moving arm 346 of the picking component 34. The inner wall of the core yarn roll squeezes the top cap 344, causing its compression spring 345 to retract inward. After the core yarn roll is fully fitted into place, the spring 345 rebounds and pushes the top cap 344 outward to tighten, thus locking the core yarn roll in an elastic lock. Finally, the drive structure 2 drives all the picking components 34 and the core yarn roll to move to the target station along the first track 112, through the changing component 12 to complete the track switching, and complete the multi-station synchronous core yarn conveying operation.
