Description

[Technical field]

[0001] The invention relates to the technical field of spinning machinery, and in particular to an elasticized intelligent yarn mending system and a method thereof. [Background technology]

[0002] In traditional textile production lines, yarn hanging and yarn changing usually rely on manual operations, which is not only inefficient but also prone to human errors. With the rapid development of the textile industry, intelligent production has become an inevitable trend to improve efficiency, reduce costs and optimize 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 automation equipment. However, in practical applications, the flexibility and adaptability of these automation systems still have certain limitations.

[0003] For example, traditional yarn-texturing frames are mostly fixed designs, which make insufficient use of space and require shutdown to replace yarn bobbins, affecting production rhythm; manual operation is cumbersome, increasing labor costs, and cannot adapt to the rapid replacement of various specifications of yarn, limiting the improvement of production efficiency. In recent years, although some improved yarn hanging devices have appeared on the market, they generally have problems such as complex structure and inconvenient operation.

[0004] At present, common solutions include using manual adjustment mechanisms to adjust the yarn hanging position, or adding additional drive devices to achieve automatic yarn change. Although the manual adjustment method is low in cost, it is inefficient and prone to operating errors. Although it can increase the speed of yarn change, it still relies on manual loading and unloading, and has limited ability to adapt to complex production environments. Although the automatic yarn changing device can improve production efficiency, due to its complex mechanical structure, it has high maintenance costs and a high failure rate.

[0005] The current forms of yarn mending 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 unreasonable, and cannot cope with the complex and changing production environment. The system integration is low, and it is difficult to seamlessly connect with other processes to form a closed-loop control. [Summary of the invention]

[0016] Furthermore, the standard wire car is transported to the standard wire car station by a transport trolley, and is driven by the transport trolley to rotate, turn and change position.

[0017] Furthermore, the transport trolley is a jack-up type AGV trolley.

[0018] Furthermore, a rotating table is provided on the standard wire turning station. When the standard wire turning station is used in conjunction with the standard wire turning buffer area, a pair of upper wire guide rails are provided on one side of the rotating table close to the standard wire turning buffer area.

[0019] The second technical problem to be solved by the present invention is to provide an intelligent elastic yarn replenishing method, whose structural system adopts a separate elastic yarn frame and a multi-level buffer area, which can greatly improve the space utilization of the equipment and the efficiency of replacing the yarn bobbin. Its various processes are reasonably arranged, 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 of the above technical problems in this way:

[0021] A method for adding elasticity and intelligent yarn mending, the method for adding elasticity and intelligent yarn mending is realized based on the system for adding elasticity and intelligent yarn mending, and the steps of the method for adding elasticity and intelligent yarn mending 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 the control system matches each yarn car space with each full-thread yarn car monomer in the adjacent first-level full-thread yarn car buffer area, it performs driving route planning, and deploys each transport trolley to send the full-thread yarn car monomer from each of the first-level full-thread yarn car buffer areas into the corresponding yarn car space of the separated type elastic yarn frame. The specific operation is: the transport trolley enters the corresponding first-level full-thread yarn car buffer through the driving route planned by the control system, drills into the bottom of the full-thread yarn car monomer, stops when the corresponding third ground locator is identified, and then identifies the identity code at the bottom of the yarn car monomer;

[0023] When the recognized identity code matches the one assigned by the control system, the transport trolley lifts up the yarn car unit and transports the yarn car unit according to the driving route planned by the control system. When the first ground locator corresponding to the current yarn car unit is recognized, the yarn car unit is sent into the corresponding yarn car space; when the second ground identifier is recognized, the vehicle stops and puts down the yarn car unit; then it returns to the driving route planned by the control system and continues to transport the yarn car unit;

[0024] Step 2, the yarn in the yarn bobbin of the yarn car body passes through the corresponding wire guide rod and enters the false twisting area for false twisting. The control system predicts the use time of the current yarn bobbin according to the wire guide speed in the false twisting area; when the yarn of the separate elastic yarn frame is used up, the control system matches the yarn car body with empty yarn in each yarn car space with the parking point of the adjacent first-level empty yarn car buffer area, and at the same time matches the yarn car body with full yarn in the adjacent first-level full yarn car buffer area with each yarn car space, and then plans the driving route, deploys each transport trolley from each yarn car space, sends the yarn car body with empty yarn into the first-level empty yarn car buffer area, and then sends the yarn car body with full yarn in the adjacent first-level full yarn car buffer area into the corresponding yarn car space of the separate elastic yarn frame;

[0025] Step 3, while the false twisting workshop continues the false twisting work, the control system matches the yarn car monomers of hollow yarn in the first-level empty yarn car buffer area with the parking points of the second-level empty yarn car buffer area, and matches the yarn car monomers of full yarn in the second-level full yarn car buffer area with the parking points of the first-level full yarn car buffer area; then deploy each transport trolley to send the yarn car monomers of hollow yarn in each of the first-level empty yarn car buffer areas into the second-level empty yarn car buffer area, and then send the yarn car monomers of full yarn from the second-level full yarn car buffer area into each of the first-level full yarn car buffer areas; complete the deployment of yarn car monomers in the first and second-level buffer areas;

[0026] Step 4: The control system dispatches a transport trolley to move the empty yarn car body in the secondary empty yarn car buffer area to the yarn loading station in the yarn loading area, and the yarn changing robot removes the empty yarn tubes on both sides of the yarn car body and inserts them into the full yarn tubes neatly arranged in the yarn loading station to realize the replacement of the yarn tubes; when all the yarn tubes on the yarn car body are replaced, the transport trolley will send them to the secondary full yarn car buffer area;

[0027] When the yarn loading station adopts the standard silk car station, it is used in conjunction with the standard silk car, on which fully rolled yarn tubes are hung; when the yarn tubes of the standard silk car on the standard silk car station are taken out, a new fully rolled standard silk car can be pushed out from the standard silk car buffer area for replacement; or a track-based yarn loading structure can be used to directly add fully rolled yarn tubes from the yarn tube buffer rack to the standard silk car.

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

[0029] The advantages of the present invention are:

[0030] The texturizing yarn frame of the present invention is composed of a fixed yarn frame limiting structure and a plurality of separate and movable yarn car monomers. When the yarn on the texturizing yarn frame is used up, another group of full yarn car monomers can be directly replaced, which greatly improves the space utilization rate of the equipment, improves the efficiency of replacing yarn tubes and production efficiency, and reduces the labor intensity.

[0031] At the same time, the yarn car monomer structure of the present invention is reasonably designed, which simplifies the yarn hanging structure, reduces unnecessary complex components, avoids the interference of redundant components, and improves the space utilization rate; the positions of the yarn hanging bracket and the yarn hanging arm are reset, and the space setting is more reasonable, so that when the yarn changing robot is used to replace the yarn tube, it only needs to be located in front of the yarn car monomer to realize the replacement of the four groups of yarn tubes on the left and right, and there is no need to rotate the yarn hanging structure back and forth, saving operating space. One yarn changing robot can simultaneously correspond to the replacement of yarn tubes of multiple yarn car monomers, which can greatly improve the production efficiency. The tail of the yarn hanging arm is slightly tilted upward, which can limit the yarn tube and prevent it from falling when rotating. The bottom is provided with a running wheel for easy manual movement, and a limiter is provided on the running wheel to ensure the stability during the replacement of the yarn tube and production, and improve the product quality.

[0032] The present invention is provided with a first-level full-thread car buffer area, a first-level empty-thread car buffer area, and a second-level full-thread car buffer area and a second-level empty-thread car buffer area. The first-level buffer area is arranged near the false twist area, which is convenient for the rapid replenishment and transfer of the hollow yarn and full-thread yarn car monomers in the separated elastic yarn frame, greatly reducing the yarn replenishment time; when the yarn replenishment is completed, the false twist workshop continues the false twisting work while carrying out the deployment of the empty yarn and full-thread yarn car monomers in the first-level buffer area and the second-level buffer area, which does not occupy the production time and is convenient for the convenience of yarn replenishment again; the second-level buffer area is arranged near the upper yarn area, which can save working time and has strong independence, that is, it does not affect the movement and replacement of the yarn car monomers in the false twist workshop, nor does it affect the deployment route of the yarn car monomers between the first-level buffer area and the second-level buffer area. That is, by setting up multiple levels of buffer areas, the present invention makes the replenishment and deployment of the empty yarn car and the full yarn car more efficient and convenient, greatly shortens the production interruption time caused by changing cars, greatly shortens the time consumption of a single cycle, and improves the overall production efficiency. The reasonable design of the multi-level buffer area not only ensures the normal operation of the false twisting workshop, but also simplifies the allocation routes between the buffer area and the work area, without interfering with each other, thus improving the independence and efficiency of the operation.

[0033] In addition, the present invention adopts the modes of manually assisted yarn feeding and robot assisted yarn feeding, and the man-machine combination can meet the problem of automatic yarn feeding of various forms of whole package products.

[0058] The present invention also relates to an elastic intelligent yarn mending method, which is implemented based on the elastic intelligent yarn mending system. The intelligent yarn mending method has the following steps: numbering the first ground locator 8, the second ground locator 9, the third ground locator (not shown) and the fourth ground locator 10 respectively;

[0059] Step 1: After the control system matches each yarn car space 1211 with each full-thread yarn car monomer 123 in the adjacent first-level full-thread yarn car buffer area 14, it performs driving route planning, and deploys each AGV trolley 3 to send the full-thread yarn car monomer 123 from each of the first-level full-thread yarn car buffer areas 14 into the corresponding yarn car space 1211 of the separated type elastic yarn frame 12. The specific operation is: the AGV trolley 3 enters the corresponding first-level full-thread yarn car buffer area 14 through the driving route planned by the control system, drills into the bottom of the full-thread yarn car monomer 123, stops when the corresponding third ground locator is recognized, and then recognizes the identity identification code 1233 at the bottom of the yarn car monomer 123;

[0060] When the recognized identity code 1233 matches the one assigned by the control system, the AGV trolley 3 lifts up the yarn car monomer 123 and transports the yarn car monomer 123 according to the driving route planned by the control system. When the first ground locator 8 corresponding to the current yarn car monomer 123 is recognized, the yarn car monomer 123 is sent into the corresponding yarn car space 1211; when the second ground identifier 9 is recognized, the AGV trolley 3 stops and puts down the yarn car monomer 123; then it returns to the driving route planned by the control system to continue transporting other yarn car monomers 123;

[0061] Step 2: The yarn in the yarn bobbin 100 of the yarn carrier unit 123 passes through the corresponding wire guide rod 122 and enters the false twisting zone 11 for false twisting. The control system predicts the use time of the current yarn bobbin 100 according to the wire guide speed of the false twisting zone 11 and prompts the operator;

[0062] When the yarn of the separate elastic yarn frame 12 is used up, the control system matches the yarn car monomers 123 with empty yarns in each yarn car space 1211 with the parking point of the adjacent first-level empty yarn car buffer area 15 (i.e., the third ground locator), and at the same time matches the yarn car monomers 123 with full yarns in the adjacent first-level full yarn car buffer area 14 with each yarn car space 1211 that needs to be supplemented with yarn, and then plans the driving route, deploys each AGV trolley 3 to send the yarn car monomers 123 with empty yarns from each yarn car space 1211 into the first-level empty yarn car buffer area 15, and then sends the yarn car monomers 123 with full yarns in the adjacent first-level full yarn car buffer area 14 into the corresponding yarn car space 1211 of the separate elastic yarn frame 12;

[0063] Step 3, while the false twisting workshop 1 continues the false twisting work, the control system matches the yarn car monomer 123 of the hollow yarn in the first-level empty yarn car buffer area 15 with the parking point of the second-level empty yarn car buffer area 22 (i.e., the fourth ground locator 10), and matches the yarn car monomer 123 of the full yarn in the second-level full yarn car buffer area 21 with the parking point of the first-level full yarn car buffer area 14 (i.e., the third ground locator); then deploy each AGV trolley 3 to send the yarn car monomer 123 of the hollow yarn in each of the first-level empty yarn car buffer areas 15 into the second-level empty yarn car buffer area 22, and then send the yarn car monomer 123 of the full yarn from the second-level full yarn car buffer area 21 into each first-level full yarn car buffer area 14; complete the deployment of the yarn car monomer 123 in the first and second-level buffer areas;

[0064] Step 4, the control system deploys the AGV trolley 3 to move the empty yarn car body 123 in the secondary empty yarn car buffer area 22 to the yarn loading station 232 of the yarn loading area 23, and the yarn changing robot 231 removes the empty yarn tubes on both sides of the yarn car body 123 and inserts them into the full-rolled yarn tubes 100 neatly arranged in the yarn loading station 233 to realize the replacement of the yarn tubes 100; when all the yarn tubes 100 on the yarn car body 123 are replaced, the AGV trolley 3 sends them to the secondary full-rolled yarn car buffer area 21;

[0065] When the yarn loading station 233 adopts the standard silk car station, it is used in conjunction with the standard silk car 5, on which the standard silk car 5 is hung with fully rolled yarn tubes 100; when the yarn tubes 100 of the standard silk car 5 on the standard silk car station are taken out, a new fully rolled standard silk car 5 can be pushed out from the standard silk car buffer area 234 for replacement; or a track-based yarn loading structure can be used to directly add fully rolled yarn tubes to the standard silk car 5 from the yarn tube buffer rack 235.

[0066] The working time of each false twist zone 11 is staggered. The yarn filling time of each false twist zone 11 can be staggered to avoid crowded yarn filling, which leads to congestion of the walking route and various abnormal situations, and waiting for way to make way, which leads to a longer yarn filling cycle; staggered yarn filling time and taking turns to fill yarn can also reduce the use of AGV carts and reduce costs.

[0067] In summary, the elastic yarn frame of the present invention is composed of a fixed yarn frame limiting structure and a plurality of separate, movable yarn car units. When the yarn on the elastic yarn frame is used up, another group of full yarn car units can be directly replaced, which greatly improves the space utilization of the equipment, improves the efficiency of replacing yarn tubes and production efficiency, and reduces manual labor intensity.

[0068] At the same time, the yarn car monomer structure of the present invention is reasonably designed, which simplifies the yarn hanging structure, reduces unnecessary complex components, avoids the interference of redundant components, and improves the space utilization rate; the positions of the yarn hanging bracket and the yarn hanging arm are reset, and the space setting is more reasonable, so that when the yarn changing robot is used to replace the yarn tube, it only needs to be located in front of the yarn car monomer to realize the replacement of the four groups of yarn tubes on the left and right, and there is no need to rotate the yarn hanging structure back and forth, saving operating space. One yarn changing robot can simultaneously correspond to the replacement of yarn tubes of multiple yarn car monomers, which can greatly improve the production efficiency. The tail of the yarn hanging arm is slightly tilted upward, which can limit the yarn tube and prevent it from falling when rotating. The bottom is provided with a running wheel for easy manual movement, and a limiter is provided on the running wheel to ensure the stability during the replacement of the yarn tube and production, and improve the product quality.

[0069] The present invention is provided with a first-level full-thread car buffer area, a first-level empty-thread car buffer area, and a second-level full-thread car buffer area and a second-level empty-thread car buffer area. The first-level buffer area is arranged near the false twist area, which is convenient for the rapid replenishment and transfer of the hollow yarn and full-thread yarn car monomers in the separated elastic yarn frame, greatly reducing the yarn replenishment time; when the yarn replenishment is completed, the false twist workshop continues the false twisting work while carrying out the deployment of the empty yarn and full-thread yarn car monomers in the first-level buffer area and the second-level buffer area, which does not occupy the production time and is convenient for the convenience of yarn replenishment again; the second-level buffer area is arranged near the upper yarn area, which can save working time and has strong independence, that is, it does not affect the movement and replacement of the yarn car monomers in the false twist workshop, nor does it affect the deployment route of the yarn car monomers between the first-level buffer area and the second-level buffer area. That is, by setting up multiple levels of buffer areas, the present invention makes the replenishment and deployment of the empty yarn car and the full yarn car more efficient and convenient, greatly shortens the production interruption time caused by changing cars, greatly shortens the time consumption of a single cycle, and improves the overall production efficiency. The reasonable design of the multi-level buffer area not only ensures the normal operation of the false twisting workshop, but also simplifies the allocation routes between the buffer area and the work area, without interfering with each other, thus improving the independence and efficiency of the operation.

[0070] In addition, the present invention adopts the modes of manually assisted yarn feeding and robot assisted yarn feeding, and the man-machine combination can meet the problem of automatic yarn feeding of various forms of whole package products.

[0071] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
