Description

[Technical Field]

[0001] This invention relates to the field of spinning machinery technology, specifically to an intelligent texturing and yarn replenishment system and method. [Background Technology]

[0002] In traditional textile production lines, yarn hanging and changing typically rely on manual operation, which is not only inefficient but also prone to human error. With the rapid development of the textile industry, intelligent manufacturing has become an inevitable trend for improving efficiency, reducing costs, and optimizing quality. In recent years, with the rise of the concept of intelligent manufacturing, more and more companies have begun to explore how to improve production efficiency and product quality, and reduce labor costs, by introducing robotics and automated equipment. However, in practical applications, the flexibility and adaptability of these automated systems still have certain limitations.

[0003] For example, traditional texturing yarn racks are mostly fixed designs, which result in insufficient space utilization. Changing yarn bobbins requires machine downtime, affecting production rhythm; manual operation is cumbersome, increasing labor costs, and cannot adapt to the need for rapid changes in various yarn specifications, thus limiting the improvement of production efficiency. In recent years, although some improved yarn hanging devices have appeared on the market, they generally suffer from problems such as complex structure and inconvenient operation.

[0004] Currently, common solutions include using manual adjustment mechanisms to adjust the yarn hanging position, or adding additional drive devices to achieve automatic yarn changing. Although manual adjustment is lower in cost, it is inefficient and prone to operational errors. While it can increase yarn changing speed, it still relies on manual loading and unloading and has limited adaptability to complex production environments. On the other hand, automatic yarn changing devices can improve production efficiency, but due to their complex mechanical structure, they have high maintenance costs and a high failure rate.

[0005] The current yarn repair methods on the market have the following problems: First, the low positioning accuracy leads to a low success rate; second, the structural design and functional areas are not reasonable, which makes it unable to cope with complex and ever-changing production environments, and the system integration is low, making it difficult to seamlessly connect with other processes to form a closed-loop control. [Summary of the Invention]

[0006] One of the technical problems to be solved by this invention is to provide an intelligent texturing yarn replenishment system, which adopts a separate texturing yarn rack and a multi-level buffer area, which can greatly improve the space utilization of the equipment, improve the efficiency of yarn bobbin replacement, and make the replenishment and allocation of empty yarn cars and full yarn cars more efficient and convenient, significantly shortening the time consumption of a single cycle and improving the overall production efficiency.

[0007] The present invention achieves one of the above-mentioned technical problems in the following way:

[0008] An intelligent texturing and yarn replenishment system includes a false twist workshop, a yarn changing workshop, a transport trolley, a travel route, and a control system. The false twist workshop includes multiple false twist zones, separate texturing frames, a control cabinet, a primary full-yarn buffer zone, and a primary empty-yarn buffer zone. Separate texturing frames are installed on both sides of each false twist zone, and a control cabinet is installed at the end of each separate texturing frame. Each false twist zone has a corresponding primary full-yarn buffer zone and a primary empty-yarn buffer zone at its end, and the primary full-yarn buffer zones and primary empty-yarn buffer zones are arranged adjacent to each other.

[0009] The detachable texturing frame includes a frame limiting structure, multiple guide rods, and multiple individual yarn carriages. The frame limiting structure divides the space into multiple yarn carriage spaces for precise positioning of the individual yarn carriages. A limiting rod is provided between adjacent yarn carriage spaces, and each guide rod is fixed to its corresponding limiting rod. Each individual yarn carriage is positioned within its respective space. Each individual yarn carriage includes a carriage base, two yarn hanging brackets, an identification code, and wheels. The two yarn hanging brackets are vertically positioned at the center of the front and rear sides of the carriage base, and the height of each yarn hanging bracket is lower than the frame limiting structure. The identification code is located below the individual yarn carriage, and the wheels are arranged around the bottom of the carriage base. Fixed rods are provided on both sides of each yarn hanging bracket, and multiple yarn hanging arms are evenly spaced from bottom to top on each fixed rod. Each yarn hanging arm faces left and right, and the angle between it and the horizontal center line is 10° to 60°. The tail of each yarn hanging arm is slightly upturned.

[0010] The yarn changing workshop includes multiple secondary full yarn car buffer areas, secondary empty yarn car buffer areas, and a yarn loading area. The secondary full yarn car buffer areas and secondary empty yarn car buffer areas are located near the false twist workshop. The yarn loading area includes a yarn changing robot, multiple yarn loading stations, and yarn loading stations. Each yarn loading station and yarn loading station is located adjacent to the corresponding yarn changing robot.

[0011] The yarn loading station is at least one of a manual yarn loading station and a standard yarn loading station. When the manual yarn loading station is used, the packaged yarn bobbins are unpacked manually and neatly stacked on the manual yarn loading station. When the standard yarn loading station is used, it is used in conjunction with a standard yarn loading machine, which holds a full roll of yarn bobbins. A standard yarn loading machine buffer area is provided on one side of the standard yarn loading station, and a full roll of standard yarn loading machine is placed in the buffer area. Alternatively, a yarn bobbin buffer rack is provided on one side of the standard yarn loading station, and a full roll of yarn bobbins is hung on the buffer rack. A rail-mounted yarn loading structure is provided above the standard yarn loading station and the yarn bobbin buffer rack, and a mobile bobbin unloading machine or a robotic arm is installed on the rail-mounted yarn loading structure.

[0012] The primary and secondary full-yarn trolley buffer areas are used to park single yarn trolleys filled with yarn, while the primary and secondary empty-yarn trolley buffer areas are used to park single yarn trolleys filled with empty yarn. Each yarn trolley works in conjunction with a transport trolley. An identification code is located below the trolley's base. The false twist workshop and yarn changing workshop have routes for the transport trolleys. First ground locators are installed at the routes directly opposite each yarn trolley space, the primary full-yarn trolley buffer area, the primary empty-yarn trolley buffer area, the secondary full-yarn trolley buffer area, and the secondary empty-yarn trolley buffer area. A second ground locator is installed in the center of the ground corresponding to each yarn trolley space. A third ground locator is installed at the parking point within each primary full-yarn trolley buffer area and the primary empty-yarn trolley buffer area. A fourth ground locator is installed at the parking point within each secondary full-yarn trolley buffer area and the secondary empty-yarn trolley buffer area.

[0013] The control system is connected to the transport trolley, control cabinet, yarn changing robot, and robotic arm.

[0014] Furthermore, at least one of the walking wheels is provided with a limiter; the identification code is set at the base of the trolley.

[0015] Furthermore, the angle between each of the yarn-hanging arms and the horizontal center line is 45±5°.

[0016] Furthermore, the standard yarn carriage is transported to the standard yarn carriage station by a transport trolley, and is rotated and repositioned by the transport trolley.

[0017] Furthermore, the transport trolley is a lifting AGV trolley.

[0018] Furthermore, a rotary table is provided on the standard yarn car station. When the standard yarn car station is used in conjunction with the standard yarn car buffer area, a pair of upper guide rails are provided on the side of the rotary table near the standard yarn car buffer area.

[0019] The second technical problem to be solved by this invention is to provide an intelligent texturing yarn replenishment method. Its structural system adopts a separate texturing yarn rack and a multi-level buffer zone, which can greatly improve the space utilization of the equipment and the efficiency of yarn bobbin replacement. Its process settings are reasonable, making the replenishment and allocation of empty yarn cars and full yarn cars more efficient and convenient, greatly shortening the time consumption of a single cycle and improving the overall production efficiency.

[0020] The present invention achieves the second technical problem mentioned above in the following way:

[0021] A texturing intelligent yarn repair method is provided, which is based on the aforementioned texturing intelligent yarn repair system. The steps of the intelligent yarn repair method are as follows: numbering the first ground locator, the second ground locator, the third ground locator, and the fourth ground locator respectively.

[0022] Step 1: After matching each yarn car space with each full yarn car unit in the adjacent first-level full yarn car buffer area, the control system plans the driving route and dispatches each transport trolley from each of the first-level full yarn car buffer areas to send the full yarn car unit into the corresponding yarn car space of the separate texturing frame. Specifically, the transport trolley enters the corresponding first-level full yarn car buffer area through the driving route planned by the control system, crawls into the bottom of the full yarn car unit, stops when the corresponding third ground locator is identified, and then identifies the identification code at the bottom of the yarn car unit.

[0023] When the identified identification code matches the one assigned by the control system, the transport trolley lifts the yarn cart unit and transports it along the route planned by the control system. When the first ground locator corresponding to the current yarn cart unit is identified, the yarn cart unit is sent into the corresponding yarn cart space. When the second ground locator is identified, the trolley stops and lowers the yarn cart unit. Then it returns and continues to transport the yarn cart unit along the route planned by the control system.

[0024] Step 2: The yarn in the yarn bobbin of the yarn cart is threaded through the corresponding guide rod and enters the false twist zone for false twisting. The control system predicts the current usage time of the yarn bobbin based on the guide speed in the false twist zone. When the yarn in the separate texturing frame is used up, the control system matches the empty yarn bobbin in each yarn cart space with the parking point of the adjacent first-level empty yarn cart buffer area. At the same time, it matches the full yarn bobbin in the adjacent first-level full yarn cart buffer area with each yarn cart space, performs the driving route planning, and dispatches each transport trolley to send the empty yarn bobbin from each yarn cart space into the first-level empty yarn cart buffer area, and then sends the full yarn bobbin in the adjacent first-level full yarn cart buffer area into the corresponding yarn cart space of the separate texturing frame.

[0025] Step 3: While the false twisting workshop continues the false twisting operation, the control system matches the empty yarn cart units in the primary empty yarn cart buffer area with the parking points in the secondary empty yarn cart buffer area, and matches the full yarn cart units in the secondary full yarn cart buffer area with the parking points in the primary full yarn cart buffer area. Then, the transport trolleys are dispatched to send the empty yarn cart units from the primary empty yarn cart buffer area to the secondary empty yarn cart buffer area, and then the full yarn cart units from the secondary full yarn cart buffer area are sent to the primary full yarn cart buffer area. This completes the allocation of yarn cart units between the primary and secondary buffer areas.

[0026] Step 4: The control system dispatches the transport trolley to move the empty yarn carts in the secondary empty yarn cart buffer area to the yarn loading station in the yarn loading area. The yarn changing robot removes the empty yarn bobbins on both sides of the yarn cart and puts them into the neatly arranged full rolls of yarn bobbins in the yarn loading station to replace the yarn bobbins. After all the yarn bobbins on the yarn cart have been replaced, the transport trolley then sends it into the secondary full yarn cart buffer area.

[0027] When the yarn loading station uses a standard yarn cart station, it is used in conjunction with a standard yarn cart, which is loaded with a full roll of yarn. When the yarn rolls on the standard yarn cart station are depleted, a new full standard yarn cart can be pushed out from the standard yarn cart buffer area to replace it; or a track-mounted yarn loading structure can be used to directly replenish the full roll of yarn onto the standard yarn cart from the yarn cart buffer rack.

[0028] Furthermore, the working hours of each false twisting zone are staggered.

[0029] The advantages of this invention are:

[0030] The texturing frame of the present invention consists of a fixed yarn frame limiting structure and multiple separate, movable yarn cart units. When the yarn on the texturing frame is used up, another set of full yarn cart units can be directly replaced, which greatly improves the space utilization of the equipment, increases the efficiency of yarn bobbin replacement and production efficiency, and reduces the intensity of manual labor.

[0031] Meanwhile, the yarn cart unit structure of this invention is rationally designed, simplifying the yarn hanging structure, reducing unnecessary complex parts, avoiding interference from redundant parts, and improving space utilization. The positions of the yarn hanging bracket and the yarn hanging arm have been repositioned, resulting in a more rational space arrangement. When using a yarn changing robot to replace yarn bobbins, the robot only needs to be positioned in front of the yarn cart unit to replace the four sets of yarn bobbins on the left and right sides, eliminating the need to rotate the yarn hanging structure back and forth, saving operating space. One yarn changing robot can simultaneously handle the yarn bobbin replacement of multiple yarn cart units, significantly improving production efficiency. The tail of the yarn hanging arm is slightly upturned, which can limit the yarn bobbin and prevent it from falling during rotation. The bottom is equipped with wheels for easy manual movement, and limiters on the wheels ensure stability during yarn bobbin replacement and production, improving product quality.

[0032] This invention features a primary buffer zone for full-yarn yarn, a primary buffer zone for empty-yarn yarn, and secondary buffer zones for both full-yarn and empty-yarn yarn. The primary buffer zone is located near the false twisting area, facilitating the rapid replenishment and transfer of empty and full-yarn yarn units from the separate texturing frame, significantly reducing replenishment time. After replenishment, the false twisting workshop continues its false twisting work while simultaneously adjusting the allocation of empty and full-yarn yarn units from the primary and secondary buffer zones. This approach avoids interrupting production time and facilitates future replenishment. The secondary buffer zone is located near the yarn loading area, saving working time and offering strong independence. It does not affect the movement and replacement of yarn units within the false twisting workshop, nor does it interfere with the allocation routes between the primary and secondary buffer zones. In short, by establishing multiple buffer zones, this invention makes the replenishment and allocation of empty and full-yarn yarn units more efficient and convenient, significantly reducing production interruption time caused by yarn changes, substantially shortening the time consumed per cycle, and improving overall production efficiency. The rational design of the multi-level buffer zone not only ensures the normal operation of the false twist workshop, but also simplifies the allocation route between the buffer zone and the working area, preventing mutual interference and improving the independence and efficiency of the operation.

[0033] In addition, the present invention adopts a combination of manual and robotic yarn feeding, and the human-machine combination can meet the automated yarn feeding problem of various types of packaged products. [Attached Image Description]

[0048] See appendix Figure 1-7This invention relates to an intelligent yarn replenishment system, comprising a false twist workshop 1, a yarn changing workshop 2, a lifting AGV trolley 3, a travel route 4, and a control system; the false twist workshop 1 includes multiple false twist zones 11, separate texturing yarn racks 12, a control cabinet 13, a primary full yarn buffer zone 14, and a primary empty yarn buffer zone 15. Separate texturing yarn racks 12 are respectively arranged on both sides of each false twist zone 11, and a control cabinet 13 is arranged at the end of each separate texturing yarn rack 12; each false twist zone 11 has a corresponding primary full yarn buffer zone 14 and a primary empty yarn buffer zone 15 at its end, and the primary full yarn buffer zone 14 and the primary empty yarn buffer zone 15 are arranged adjacent to each other. The false twist zones 11 can be arranged in multiple rows and columns according to actual conditions.

[0049] The split texturing yarn frame 12 includes a yarn frame limiting structure 121, multiple guide rods 122, and multiple yarn carriage units 123. The yarn frame limiting structure 121 divides the yarn carriage into multiple yarn carriage spaces 1211 for precise positioning of the yarn carriage units 123. A limiting rod 1212 is provided between adjacent yarn carriage spaces 1211, and each guide rod 122 is fixed to a corresponding limiting rod 1212. Each yarn carriage unit 123 is disposed within the yarn carriage space 1211. Each yarn carriage unit 123 includes a carriage base 1231, two yarn hanging brackets 1232, an identification code 1233, and wheels 1234. 2. The yarn hanging brackets 1232 are vertically arranged at the center of the front and rear sides of the trolley base 1231, and the height of each yarn hanging bracket 1232 is lower than the yarn frame limiting structure 121. The identification code 1233 is set at the trolley base 1231, and the traveling wheels 1234 are arranged around the bottom of the trolley base 1231. The two sides of the yarn hanging bracket 1232 are provided with fixing rods 1235, and each fixing rod 1235 is provided with multiple yarn hanging arms 1236 at equal intervals from bottom to top. Each yarn hanging arm 1236 is arranged facing the left and right sides, and the angle α with the horizontal center line is 40° to 50°. The tail of each yarn hanging arm 1236 is slightly curved upward.

[0050] The yarn changing workshop 2 includes multiple secondary full yarn car buffer areas 21, secondary empty yarn car buffer areas 22, and yarn loading area 23. The secondary full yarn car buffer areas 21 and secondary empty yarn car buffer areas 22 are located near the false twist workshop 1. The yarn loading area 23 includes a yarn changing robot 231, multiple yarn loading stations 232, and yarn loading stations 233. Each yarn loading station 232 and yarn loading station 233 is located adjacent to the corresponding yarn changing robot 231.

[0051] The yarn loading station 233 is at least one of a manual yarn loading station and a standard yarn loading station. When the manual yarn loading station is used, the packaged yarn bobbins 100 are unpacked manually and neatly stacked on the manual yarn loading station. When the standard yarn loading station is used, it is used in conjunction with a standard yarn loading machine 5, on which a full roll of yarn bobbins 100 is hung. A standard yarn loading machine buffer area 234 is provided on one side of the standard yarn loading station, and a full roll of standard yarn loading machine 5 is placed in the standard yarn loading machine buffer area 234. Alternatively, a yarn bobbin buffer rack 235 is provided on one side of the standard yarn loading station, on which a full roll of yarn bobbins 100 is hung. A rail-mounted yarn loading structure 6 is provided above the standard yarn loading station and the yarn bobbin buffer rack 235, and a mobile yarn loading machine or a robotic arm 7 is installed on the rail-mounted yarn loading structure 6.

[0052] The primary full-yarn carriage buffer area 14 and the secondary full-yarn carriage buffer area 21 are used to park full-yarn carriage units 123, and the primary empty-yarn carriage buffer area 15 and the secondary empty-yarn carriage buffer area 22 are used to park empty-yarn carriage units 123. The yarn carriage unit 123 cooperates with the AGV trolley 3, and the identification code 1233 is set below the trolley base 1231. The false twist workshop 1 and the yarn changing workshop 2 are equipped with AGV trolley travel routes 4, which are located in each of the yarn carriage spaces 1211 and the primary full-yarn carriage buffer area 14. A first ground locator 8 is installed at each of the following locations on the driving route 4, directly opposite the first-level empty yarn car buffer area 15, the second-level full yarn car buffer area 21, and the second-level empty yarn car buffer area 22: a second ground locator 9 is installed at the center of the ground corresponding to each of the yarn car spaces 1211; a third ground locator is installed at each parking point in each of the first-level full yarn car buffer area 14 and the first-level empty yarn car buffer area 15; and a fourth ground locator 10 is installed at each parking point in each of the second-level full yarn car buffer area 21 and the second-level empty yarn car buffer area 22.

[0053] The control system is electrically connected to the AGV trolley 3, control cabinet 13, yarn changing robot 231, and robotic arm 7.

[0054] In a preferred embodiment, at least one of the walking wheels 1234 is provided with a limiter.

[0055] In a preferred embodiment, the angle α between each of the yarn hanging arms 1236 and the horizontal center line is 45°.

[0056] In a preferred embodiment, the standard wire car 5 is delivered to the standard wire car station by the AGV trolley 3, and is rotated and repositioned by the AGV trolley 3.

[0057] In a preferred embodiment, the standard yarn carriage station is equipped with a rotary table 2331. When the standard yarn carriage station is used in conjunction with the standard yarn carriage buffer area 234, a pair of upper guide rails 2332 are provided on the side of the rotary table 2331 closest to the standard yarn carriage buffer area 234. The upper guide rails 2332 are used to assist the standard yarn carriage 5 in moving up and down the rotary table 2331. The rotary table 2331 is used to drive the standard yarn carriage 5 to rotate to the other side, making it easier for the yarn changing robot 231 to grab the yarn bobbin on the other side.

[0058] The present invention also relates to an intelligent yarn replenishment method, which is based on the aforementioned intelligent yarn replenishment system. The steps of the intelligent yarn replenishment method are as follows: the first ground locator 8, the second ground locator 9, the third ground locator (not shown) and the fourth ground locator 10 are numbered respectively.

[0059] Step 1: After matching each yarn carriage space 1211 with each full yarn carriage unit 123 in the adjacent first-level full yarn carriage buffer area 14, the control system performs driving route planning and dispatches each AGV trolley 3 to send the full yarn carriage unit 123 from each of the first-level full yarn carriage buffer areas 14 into the corresponding yarn carriage space 1211 of the separate texturing frame 12. Specifically, the AGV trolley 3 enters the corresponding first-level full yarn carriage buffer 14 through the driving route planned by the control system, crawls into the bottom of the full yarn carriage unit 123, stops when the corresponding third ground locator is identified, and then identifies the identification code 1233 at the bottom of the yarn carriage unit 123.

[0060] When the identified identification code 1233 matches the one assigned by the control system, the AGV trolley 3 lifts the yarn cart unit 123 and transports the yarn cart unit 123 according to the driving route planned by the control system. When the first ground locator 8 corresponding to the current yarn cart unit 123 is identified, the yarn cart unit 123 is sent into the corresponding yarn cart space 1211. When the second ground locator 9 is identified, the AGV stops and the yarn cart unit 123 is lowered. Then it returns to the driving route planned by the control system to continue transporting other yarn cart units 123.

[0061] Step 2: The yarn in the yarn bobbin 100 of the yarn machine unit 123 is threaded into the corresponding guide rod 122 and enters the false twist zone 11 for false twisting. The control system predicts the current usage time of the yarn bobbin 100 based on the guide speed of the false twist zone 11 and prompts the operator.

[0062] When the yarn in the separate texturing frame 12 is used up, the control system matches the empty yarn cart unit 123 in each yarn cart space 1211 with the parking point (i.e., the third ground locator) of the adjacent first-level empty yarn cart buffer area 15. At the same time, it matches the full yarn cart unit 123 in the adjacent first-level full yarn cart buffer area 14 with each yarn cart space 1211 that needs to replenish yarn. Then, it plans the driving route and dispatches each AGV trolley 3 to send the empty yarn cart unit 123 from each yarn cart space 1211 into the first-level empty yarn cart buffer area 15, and then send the full yarn cart unit 123 in the adjacent first-level full yarn cart buffer area 14 into the corresponding yarn cart space 1211 of the separate texturing frame 12.

[0063] Step 3: While the false twisting workshop 1 continues the false twisting operation, the control system matches the empty yarn cart units 123 in the primary empty yarn cart buffer area 15 with the parking point (i.e., the fourth ground locator 10) in the secondary empty yarn cart buffer area 22, and matches the full yarn cart units 123 in the secondary full yarn cart buffer area 21 with the parking point (i.e., the third ground locator) in the primary full yarn cart buffer area 14. Then, each AGV trolley 3 is dispatched to send the empty yarn cart units 123 in each of the primary empty yarn cart buffer areas 15 into the secondary empty yarn cart buffer area 22, and then send the full yarn cart units 123 from the secondary full yarn cart buffer area 21 into each of the primary full yarn cart buffer areas 14; thus completing the dispatching of the yarn cart units 123 in the primary and secondary buffer areas.

[0064] Step 4: The control system dispatches the AGV trolley 3 to move the empty yarn cart unit 123 in the secondary empty yarn cart buffer area 22 to the yarn loading station 232 in the yarn loading area 23. The yarn changing robot 231 removes the empty yarn bobbins on both sides of the yarn cart unit 123 and puts them into the neatly arranged full rolls of yarn bobbins 100 in the yarn loading station 233 to replace the yarn bobbins 100. After all the yarn bobbins 100 on the yarn cart unit 123 have been replaced, the AGV trolley 3 then sends it into the secondary full yarn cart buffer area 21.

[0065] When the yarn loading station 233 uses a standard yarn loading station, it is used in conjunction with a standard yarn loading 5, which is equipped with a full roll of yarn bobbin 100. When the yarn bobbin 100 of the standard yarn loading 5 at the standard yarn loading station is depleted, a new full standard yarn loading 5 can be pushed out from the standard yarn loading buffer area 234 to replace it; or a track-mounted yarn loading structure can be used to directly replenish the full roll of yarn bobbin to the standard yarn loading 5 from the yarn bobbin buffer rack 235.

[0066] The working times of each false twist zone 11 are staggered. This allows the yarn replenishment time of each false twist zone 11 to be staggered, avoiding congestion of the walking route caused by clustered yarn replenishment, which could lead to various abnormal situations, as well as waiting for the yarn to be cleared, which would lengthen the yarn replenishment cycle. The staggered yarn replenishment time also reduces the number of AGV carts used, thus reducing costs.

[0067] In summary, the texturing frame of the present invention consists of a fixed yarn frame limiting structure and multiple separate, movable yarn cart units. When the yarn on the texturing frame is used up, another set of full yarn cart units can be directly replaced, which greatly improves the space utilization of the equipment, increases the efficiency of yarn bobbin replacement and production efficiency, and reduces the intensity of manual labor.

[0068] Meanwhile, the yarn cart unit structure of this invention is rationally designed, simplifying the yarn hanging structure, reducing unnecessary complex parts, avoiding interference from redundant parts, and improving space utilization. The positions of the yarn hanging bracket and the yarn hanging arm have been repositioned, resulting in a more rational space arrangement. When using a yarn changing robot to replace yarn bobbins, the robot only needs to be positioned in front of the yarn cart unit to replace the four sets of yarn bobbins on the left and right sides, eliminating the need to rotate the yarn hanging structure back and forth, saving operating space. One yarn changing robot can simultaneously handle the yarn bobbin replacement of multiple yarn cart units, significantly improving production efficiency. The tail of the yarn hanging arm is slightly upturned, which can limit the yarn bobbin and prevent it from falling during rotation. The bottom is equipped with wheels for easy manual movement, and limiters on the wheels ensure stability during yarn bobbin replacement and production, improving product quality.

[0069] This invention features a primary buffer zone for full-yarn yarn, a primary buffer zone for empty-yarn yarn, and secondary buffer zones for both full-yarn and empty-yarn yarn. The primary buffer zone is located near the false twisting area, facilitating the rapid replenishment and transfer of empty and full-yarn yarn units from the separate texturing frame, significantly reducing replenishment time. After replenishment, the false twisting workshop continues its false twisting work while simultaneously adjusting the allocation of empty and full-yarn yarn units from the primary and secondary buffer zones. This approach avoids interrupting production time and facilitates future replenishment. The secondary buffer zone is located near the yarn loading area, saving working time and offering strong independence. It does not affect the movement and replacement of yarn units within the false twisting workshop, nor does it interfere with the allocation routes between the primary and secondary buffer zones. In short, by establishing multiple buffer zones, this invention makes the replenishment and allocation of empty and full-yarn yarn units more efficient and convenient, significantly reducing production interruption time caused by yarn changes, substantially shortening the time consumed per cycle, and improving overall production efficiency. The rational design of the multi-level buffer zone not only ensures the normal operation of the false twist workshop, but also simplifies the allocation route between the buffer zone and the working area, preventing mutual interference and improving the independence and efficiency of the operation.

[0070] In addition, the present invention adopts a combination of manual and robotic yarn feeding, and the human-machine combination can meet the automated yarn feeding problem of various types of packaged products.

7. A method for intelligent texturing and yarn replenishment, characterized in that: The intelligent yarn repair method is implemented based on an intelligent yarn repair system for texturing as described in any one of claims 1-6. The steps of the intelligent yarn repair method are as follows: number the first ground locator, the second ground locator, the third ground locator and the fourth ground locator respectively. Step 1: After matching each yarn car space with each full yarn car unit in the adjacent first-level full yarn car buffer area, the control system plans the driving route and dispatches each transport trolley from each of the first-level full yarn car buffer areas to send the full yarn car unit into the corresponding yarn car space of the separate texturing frame. Specifically, the transport trolley enters the corresponding first-level full yarn car buffer area through the driving route planned by the control system, crawls into the bottom of the full yarn car unit, stops when the corresponding third ground locator is identified, and then identifies the identification code at the bottom of the yarn car unit. When the identified identification code matches the one assigned by the control system, the transport trolley lifts the yarn cart unit and transports it along the route planned by the control system. When the first ground locator corresponding to the current yarn cart unit is identified, the yarn cart unit is sent into the corresponding yarn cart space. When the second ground locator is identified, the trolley stops and lowers the yarn cart unit. Then it returns and continues to transport the yarn cart unit along the route planned by the control system. Step 2: The yarn in the yarn bobbin of the yarn cart is threaded through the corresponding guide rod and enters the false twist zone for false twisting. The control system predicts the current usage time of the yarn bobbin based on the guide speed in the false twist zone. When the yarn in the separate texturing frame is used up, the control system matches the empty yarn bobbin in each yarn cart space with the parking point of the adjacent first-level empty yarn cart buffer area. At the same time, it matches the full yarn bobbin in the adjacent first-level full yarn cart buffer area with each yarn cart space, performs the driving route planning, and dispatches each transport trolley to send the empty yarn bobbin from each yarn cart space into the first-level empty yarn cart buffer area, and then sends the full yarn bobbin in the adjacent first-level full yarn cart buffer area into the corresponding yarn cart space of the separate texturing frame. Step 3: While the false twisting workshop continues the false twisting operation, the control system matches the single empty yarn cart in the primary empty yarn cart buffer area with the stopping point in the secondary empty yarn cart buffer area, and matches the single full yarn cart in the secondary full yarn cart buffer area with the stopping point in the primary full yarn cart buffer area. Then, each transport trolley is dispatched to send the empty yarn single units from the first-level empty yarn car buffer area to the second-level empty yarn car buffer area, and then the full yarn single units from the second-level full yarn car buffer area are sent to the first-level full yarn car buffer area; thus completing the dispatching of yarn single units in the first-level and second-level buffer areas. Step 4: The control system dispatches the transport trolley to move the empty yarn carts in the secondary empty yarn cart buffer area to the yarn loading station in the yarn loading area. The yarn changing robot removes the empty yarn bobbins on both sides of the yarn cart and puts them into the neatly arranged full rolls of yarn bobbins in the yarn loading station to replace the yarn bobbins. After all the yarn bobbins on the yarn cart have been replaced, the transport trolley then sends it into the secondary full yarn cart buffer area. When the yarn loading station uses a standard yarn cart station, it is used in conjunction with a standard yarn cart, which is loaded with a full roll of yarn. When the yarn rolls on the standard yarn cart station are depleted, a new full standard yarn cart can be pushed out from the standard yarn cart buffer area to replace it; or a track-mounted yarn loading structure can be used to directly replenish the full roll of yarn onto the standard yarn cart from the yarn cart buffer rack.

8. The intelligent texturing and patching method as described in claim 7, characterized in that: The working hours of each false twist zone are staggered.
