[0002] On the traditional textile production line, hanging and changing yarn usually rely on manual operation, which is not only inefficient, but also prone to human error. 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 Industry 4.0 and intelligent manufacturing, more and more enterprises have begun to explore how to introduce robot technology and automation equipment to improve production efficiency and product quality, and reduce labor costs. However, in practical application, the flexibility and adaptability of these automation systems still have certain limitations.

[0048] The working process of the elasticized intelligent yarn supplementing system is as follows:
[0049] The first ground positioner 8, the second ground positioner 9, the third ground positioner (not shown in the figure) and the fourth ground positioner 10 are numbered respectively.
[0050] Step 1, after the control system matches each yarn car space 1211 and each full yarn car unit 123 in the first full yarn car buffer area 14 adjacent thereto, it plans a driving route and allocates each AGV car 3 to send the full yarn car unit 123 from each first full yarn car buffer area 14 into the corresponding yarn car space 1211 of the separated elastic yarn rack 12. Specifically, the AGV car 3 enters the corresponding first full yarn car buffer area 14 through the driving route planned by the control system, penetrates into the bottom of the full yarn car unit 123, stops when the corresponding third ground locator is recognized, and then recognizes the identity code 1233 at the bottom of the yarn car unit 123;
[0051] When the recognized identity code 1233 matches the allocation of the control system, the AGV car 3 lifts the yarn car unit 123 and transports it according to the driving route planned by the control system. When the first ground locator 8 corresponding to the current yarn car unit 123 is recognized, the yarn car unit 123 is sent into the corresponding yarn car space 1211. When the second ground locator 9 is recognized, the car stops and the yarn car unit 123 is lowered. Then it returns to continue transporting other yarn car units 123 according to the driving route planned by the control system;
[0052] Step 2, the yarn in the yarn drum 100 of the yarn car 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 use time of the current yarn drum 100 according to the guide speed of the false twist zone 11 and prompts the operator;
[0053] When the yarn in the separated elastic yarn rack 12 is used up, the control system matches each empty yarn car unit 123 in each yarn car space 1211 with the parking point (i.e. the third ground locator) of the first empty yarn car buffer area 15 adjacent thereto, and at the same time matches the full yarn car unit 123 in the adjacent first full yarn car buffer area 14 with each yarn car space 1211 that needs to be replenished with yarn. Then it plans a driving route and allocates each AGV car 3 to send the empty yarn car unit 123 from each yarn car space 1211 into the first empty yarn car buffer area 15, and then sends the full yarn car unit 123 in the adjacent first full yarn car buffer area 14 into the corresponding yarn car space 1211 of the separated elastic yarn rack 12;
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] In summary, the texturing yarn frame of this utility model consists of a fixed yarn frame limiting structure and multiple separate, movable yarn cart units. When the yarn on the texturing yarn 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.
[0059] Meanwhile, the yarn frame single body structure is reasonable in design, the yarn hanging structure is simplified, unnecessary complex components are reduced, interference of the redundant components is avoided, and space utilization is improved; the positions of the yarn hanging support and the yarn hanging support arm are re-set, space setting is more reasonable, when the yarn changing robot is used to change the yarn bobbins, only the front of the yarn frame single body is needed to be located, left and right four groups of the bobbins can be changed, the yarn hanging structure does not need to be rotated back and forth, operation space is saved, one yarn changing robot can correspond to the bobbins of multiple yarn frame single bodies to change, and production efficiency can be greatly improved.
[0060] The utility model sets up first full silk car buffer area, first empty silk car buffer area and second full silk car buffer area, second empty silk car buffer area, first buffer area is close to false twist zone setting, convenient for quick replenishment transfer of empty silk, full silk yarn frame single body in separation type elastic yarn frame, greatly reduce the time of replenishing yarn, when replenishing yarn is completed, false twist car room is in the false twist work at the same time, carry out the allocation of empty silk, full silk yarn frame single body of first buffer area, second buffer area, neither occupy production time, nor facilitate the convenience of replenishing yarn again, second buffer area is close to setting of the yarn area, can save working hours, and independence is strong, namely, do not affect the yarn frame single body movement replacement in false twist car room, also do not affect the allocation route of yarn frame single body between first buffer area, second buffer area. That is, the utility model discloses through setting multistage buffer area, the replenishment and allocation of empty silk car and full silk car are more efficient and convenient, greatly shorten the production interruption time caused by changing car, greatly shorten the time consumption of single cycle, improve the overall production efficiency. The reasonable design of multistage buffer area not only guarantees the normal operation in false twist car room, simplifies the allocation route between buffer area and work area, does not interfere with each other, improves the independence and efficiency of operation.
[0061] In addition, the utility model adopts the mode of manual auxiliary yarn feeding and mechanical hand auxiliary yarn feeding, and the man-machine combination can meet the automatic yarn feeding problem of various forms of whole package products.
