Abstract
Description
Technical Field
[0001] This invention relates to the field of textile production technology, and more specifically to a method and system for collectively changing combed and parallel sliver cans. Background Technology
[0002] Carding and drawing are important production processes in the spinning process. The current connection between these two processes in the workshop is as follows: the sliver produced by the carding machine is coiled and loaded into sliver cans. After a certain amount is stored, it falls into the can, forming a full can. The full can is transported manually to the full can preparation area of the drawing frame for spinning. If there is an empty can among the 12 sliver cans being spun in the drawing frame, the worker pushes the full can from the full can preparation area into the working position to replace the empty can, and pulls the sliver from the full can into the drawing frame to continue production. Finally, the empty can is pulled back to the empty can stacking point of the carding machine.
[0003] During the production process, we discovered the following problems: 1. The replacement time of the 12 sliver cans on the drawing frame is uncertain, requiring workers to increase patrols and perform frequent can replacement operations, resulting in high labor intensity. 2. Manual handling is labor-intensive, time-consuming, and prone to errors during can-pulling, causing quality loss.
[0004] Therefore, proposing a method for collective barrel replacement in combing and merging is an innovative improvement on existing barrel replacement methods and transportation methods, which significantly improves production efficiency and realizes intelligent production in the combing and merging process. This is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, the present invention provides a method and system for collective barrel changing in a combing and merging process, which innovatively improves existing barrel changing methods and transportation methods, significantly increases production efficiency, and realizes an intelligent production process in the combing and merging process. To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A method for collectively changing comb-and-connect bar bins includes:
[0007] The AGV receives the full-bottle discharge position of the carding machine and outputs a full-bottle signal to transport the full-bottle to the full-bottle preparation area of the drawing frame;
[0008] When the AGV receives the preset empty can signal from the drawing frame in the spinning area, it pushes the full cans from the full can preparation area of the drawing frame to all working areas in the spinning area, and at the same time, all the cans in the working area of the drawing frame are pushed to the empty can storage area of the drawing frame; or manually, all the full cans from the full can preparation area of the drawing frame are pushed to the spinning area of the drawing frame, and at the same time, all the empty cans in the spinning area of the drawing frame are pushed to the empty can storage area of the drawing frame.
[0009] The AGV receives the empty can signal from the empty can storage area of the drawing frame and moves the empty cans from the empty can storage area of the drawing frame to the empty can placement area of the carding machine.
[0010] Optionally, the drawing frame receives an empty can output signal in the working area of the spinning zone, and stops the working process in the spinning zone when at least one working area outputs an empty can signal.
[0011] Optionally, this includes ensuring the consistency of sliver length across all sliver cans by controlling the sliver length of the carding machine and correcting for tension differences in the sliver cans at the drawing frame position.
[0012] Optionally, the AGV's handling rules are as follows: when there is an empty space in the full barrel preparation area of the drawing frame, the AGV automatically transports the full barrels from the carding machine's discharge position to the full barrel preparation area. If there are no empty spaces in the full barrel preparation areas of all drawing frames, the AGV will automatically transport the full barrels from the carding machine's discharge position to the full barrel temporary storage area until there are no empty spaces in both the full barrel preparation area and the full barrel temporary storage area.
[0013] Optionally, the arrangement rule of the full barrel preparation area of the drawing machine is to arrange the pieces sequentially from the inside out.
[0014] Optionally, a comb-and-connect bar-and-bar collective bar-changing system includes:
[0015] Barrel Signal Monitoring Module: Monitors the internal condition of the barrels using infrared sensors and outputs a signal indicating whether the barrel is empty or full.
[0016] Full barrel handling module: The AGV receives the full barrel discharge position of the carding machine, outputs a full barrel signal, and transports the full barrel to the full barrel preparation area of the drawing frame;
[0017] Empty barrel handling module: The AGV receives the empty barrel signal from the empty barrel temporary storage area of the drawing frame and transports the empty barrels from the empty barrel temporary storage area of the drawing frame to the empty barrel placement area of the carding machine;
[0018] Collective can changing module: When the drawing frame outputs a preset empty can signal in the spinning area, the full cans in the full can preparation area of the drawing frame are pushed to all working areas in the spinning area. At the same time, all the cans in the working areas of the drawing frame are pushed to the empty can temporary storage area of the drawing frame.
[0019] Optionally, a computer-readable storage medium stores a computer program that, when executed by a processor, implements a method for collectively changing bins in a comb-and-connection system.
[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a method and system for collective barrel replacement of comb-and-connected strip barrels, which has the following beneficial effects:
[0021] This invention reduces the workload of workers and improves labor efficiency by replacing frequent, piecemeal canister changes with collective canister changes; collective canister changes can reduce equipment downtime and improve equipment operating efficiency; collective canister changes can remove splice yarns, improving product quality; intelligent canister handling and changing reduces the error rate of manual canister pulling and avoids quality loss; the canister changing method of this invention realizes the automation, continuity and intelligence of the combing and merging process.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] This invention discloses a method for collective barrel replacement in comb-and-connected stripe barrels, comprising:
[0033] The AGV receives the full can discharge position signal from the carding machine and outputs a full can signal to transport the full can to the full can preparation area of the drawing frame. When the AGV receives the preset empty can signal from the drawing frame in the spinning area, it pushes the full cans in the full can preparation area of the drawing frame to all working areas in the spinning area, and at the same time, all sliver cans in the working areas of the drawing frame are pushed to the empty can storage area of the drawing frame. Alternatively, the full cans in the full can preparation area of the drawing frame can be manually pushed to the spinning area of the drawing frame, and at the same time, all empty cans in the spinning area of the drawing frame are pushed to the empty can storage area of the drawing frame. The AGV receives the empty can signal from the empty can storage area of the drawing frame and transports the empty cans in the empty can storage area of the drawing frame to the empty can placement area of the carding machine.
[0034] In Example 1, a method for collectively changing comb-and-connected bar bins includes:
[0035] The carding machine outputs a full-bottle signal at the full-bottle discharge position. The AGV receives the full-bottle signal and transports the full-bottle to the full-bottle preparation area of the drawing frame. When the drawing frame outputs a preset empty-bottle signal in the spinning area, all full-bottles in the full-bottle preparation area of the drawing frame are pushed to the spinning area of the drawing frame. At the same time, all empty-bottles in the spinning area of the drawing frame are pushed to the empty-bottle temporary storage area of the drawing frame. The empty-bottle temporary storage area of the drawing frame outputs an empty-bottle signal. The AGV receives the empty-bottle signal and transports the empty-bottles in the empty-bottle temporary storage area of the drawing frame to the empty-bottle placement area of the carding machine.
[0036] Furthermore, the full can preparation area of the drawing frame includes 12 full can placement positions; the empty can temporary storage area of the drawing frame includes 12 empty can placement positions; and the drawing frame in the spinning area includes 12 working areas.
[0037] Furthermore, the specific steps for pushing all full cans to the spinning area of the drawing frame when the drawing frame outputs a preset empty can signal are as follows: Obtain the empty can output signal of the working area of the drawing frame in the spinning area; when at least one working area outputs an empty can signal, stop the working process of all working areas in the spinning area. This also includes ensuring the consistency of sliver length across all cans by controlling the sliver length of the carding machine and correcting for tension differences in the position of the sliver cans at the drawing frame. The specific steps for pushing all full cans from the full can preparation area of the drawing frame to the spinning area of the drawing frame, while simultaneously pushing all empty cans from the spinning area of the drawing frame to the empty can storage area of the drawing frame, include: pushing 12 full cans from the full can preparation area of the drawing frame to the working area of the spinning area, while simultaneously pushing 12 sliver cans from the spinning area of the drawing frame to the empty can storage area of the drawing frame.
[0038] Furthermore, the AGV's handling rules are as follows: When there is an empty space in the full-can preparation area of the drawing frame, the AGV automatically transports the full cans from the carding machine's discharge position to the full-can preparation area. If there are no empty spaces in any of the drawing frame's full-can preparation areas, the AGV will automatically transport the full cans from the carding machine's discharge position to the full-can temporary storage area, until both the full-can preparation area and the full-can temporary storage area are completely full. This includes the fact that the full-can preparation areas of the drawing frame are arranged sequentially from the inside out.
[0039] In Example 2, a comb-and-connect bar-and-bar collective bar-changing system includes:
[0040] Barrel Signal Monitoring Module: Monitors the internal condition of the barrels using infrared sensors and outputs a signal indicating whether the barrel is empty or full.
[0041] Full barrel handling module: The AGV receives the full barrel discharge position of the carding machine, outputs a full barrel signal, and transports the full barrel to the full barrel preparation area of the drawing frame;
[0042] Empty barrel handling module: The AGV receives the empty barrel signal from the empty barrel temporary storage area of the drawing frame and transports the empty barrels from the empty barrel temporary storage area of the drawing frame to the empty barrel placement area of the carding machine;
[0043] Collective can changing module: When the drawing frame outputs a preset empty can signal in the spinning area, the full cans in the full can preparation area of the drawing frame are pushed to all working areas in the spinning area. At the same time, all the cans in the working areas of the drawing frame are pushed to the empty can temporary storage area of the drawing frame.
[0044] In Embodiment 3, a computer-readable storage medium stores a computer program that, when executed by a processor, implements the aforementioned method for collective barrel swapping in a comb-and-connection system.
[0045] In implementation 4, a method for collectively replacing barn strips is used, such as... Figure 1 As shown, it includes:
[0046] The automated guided vehicle (AGV) process replaces manual can handling: Full cans produced by the carding machine are discharged to the carding machine's discharge position. Upon receiving the full can signal, the AGV automatically transports the can to a designated location in the full can preparation area of the drawing frame. Subsequently, empty cans from the drawing frame's empty can storage area are transported to their designated empty can placement positions within the carding machine. This reciprocating automatic operation achieves continuous, unmanned transport of full and empty cans.
[0047] Collective can replacement process: When the sliver cans in the spinning area of the drawing frame are used up, the 12 full cans on the full can preparation area side of the drawing frame are pushed to the spinning area. At the same time, the 12 empty cans in the spinning area are pushed to the empty can storage area, and the full and empty can replacement operation of the 12 sliver cans is completed in one go.
[0048] In Example 5, an AGV unmanned handling and collective bucket changing method is described, such as... Figure 2 - Figure 6 As shown, it includes:
[0049] S1: The last 12 barrels of the drawing frame are spinning;
[0050] S2: AGVs deliver full buckets directly to the "full bucket preparation area" in sequence;
[0051] S3: The AGV sequentially delivers the full buckets to the "full bucket preparation area" until all 12 buckets are full;
[0052] S4: When a drum needs to be replaced, replace all 12 drums at once. Push the drum into the spinning position from the full drum side and push the empty drum out to the empty drum storage area.
[0053] S5: The AGV sequentially transports the empty buckets from the "empty bucket temporary storage area" to the carding machine, while simultaneously placing the full buckets from the carding machine sequentially into the "full bucket preparation area".
[0054] S6: Cycle through S3-S5, the AGV works according to the set rules.
[0055] like Figure 7 As shown, during this cycle, the system automatically identifies in real time that if there are no empty spaces in all full bin preparation areas, the AGV will still automatically transport the full bins discharged from the carding machine to the full bin temporary storage area until there are no empty spaces in both the full bin preparation area and the full bin temporary storage area. During this period, regardless of how many full bins are in the full bin temporary storage area, once a replacement is made, the full bins in the full bin temporary storage area must be pushed to the innermost position of the full bin preparation area and then outwards.

Similar or identical parts between embodiments can be referred to interchangeably.
