Therefore, other examples of the exemplary embodiments may have different values.

[0050] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0051] In the description and claims of the present invention, features related to the terms "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0052] First, the feeding system in the present invention will be introduced below. As Figure 1 shown, it includes a raw material warehouse and multiple production lines. The raw material warehouse includes multiple rows of shelves with a certain height. The shelves are divided into multiple layers in the height direction, and raw materials can be placed on any layer of the shelves. The shelves on both sides are single-row shelves, and the middle shelves are double-row shelves. Multiple stackers are arranged between the shelves on both sides and the middle shelves. The stacker can take out raw materials from any layer of the shelves on both sides of the stacker. As Figure 1 shown, the stacker 1 between shelf A1 and shelf A2 can take out raw materials from shelf A1 or shelf A2, and the stacker 2 between shelf B1 and shelf B2 can take out raw materials from shelf B or shelf B

[0053] The raw material warehouse can be divided into multiple warehouses, and each warehouse includes a stacker and the shelves on both sides of the stacker. As Figure 1 shown, the raw material warehouse includes shelf A1, shelf A2, shelf B1, shelf B2, shelf C1, shelf C2, shelf D1, shelf D2 and four stackers. Among them, stacker 1, shelf A1 and shelf A2 form warehouse A, stacker 2, shelf B1 and shelf B2 form warehouse B, stacker 3, shelf C1 and shelf C2 form warehouse C, and stacker 4, shelf D1 and shelf D2 form warehouse D.

[0054] As Figure 1 shown, a circular conveyor belt 1 is arranged around the shelves. The conveyor belt 1 runs in a specified direction, Figure 1 and the direction indicated by the dashed arrow in

[0055] The raw materials include a raw material barrel and a wire harness wound around the outer periphery of the raw material barrel. The production line processes the wire harness to produce a specified product. After processing, the wire harness around the raw material barrel may be used up, leaving only an empty raw material barrel. At this time, the empty raw material barrel is transported to conveyor belt 1 by the production line conveyor belt, and then the empty raw material barrel is transported to conveyor belt 3 by conveyor belt 1, and the empty raw material barrel is transported to the warehouse entrance and exit by conveyor belt 3, and finally the empty raw material barrel is taken out.

[0056] In addition, after processing, there may also be some wire harness remaining around the raw material barrel. At this time, the raw material barrel with the remaining wire harness is transported to conveyor belt 1 by the production line conveyor belt, and then the stacker removes the raw material barrel with the remaining wire harness on conveyor belt 1 and places the raw material barrel with the remaining wire harness on the shelf through the stacker.

[0057] As Figure 2 shown, this embodiment introduces a method for controlling the return of materials in an automotive wire harness production line, and the method includes steps 1100-1600.

[0058] Step 1100: After the target raw materials are used up on the target production line, place the target raw materials on the conveyor belt of the target production line.

[0059] According to the material requirements of the target production line, raw materials can be taken out from the warehouse and provided to the target production line. The raw materials include a raw material barrel and a wire harness wound outside the raw material barrel, and the target production line processes the wire harness. During the processing, the target production line may only use part of the wire harness, and there is still remaining wire harness on the raw material barrel. Since the processing requirements of the target production line have changed and other types of wire harness need to be processed, at this time, the previously remaining raw materials need to be removed from the target production line and the remaining raw materials are placed on the conveyor belt of the target production line.

[0060] Step 1200: Transport the target raw materials to the dock area of the target production line through the conveyor belt of the target production line. The dock area of the target production line is at the connection position between the conveyor belt of the target production line and the first conveyor belt.

[0061] As Figure 1 shown, the first conveyor belt is the Figure 1 conveyor belt 1 in Figure 1 , and conveyor belt 1 runs in the direction shown by the dotted line in

[0062] Step 1300: Weigh the target raw materials in the dock area of the target production line to determine the weight of the target raw materials.

[0063] The raw materials can be weighed in the dock area. For example, weighing sensors are set in the dock area to determine the weight of the raw materials through the weighing sensors.

[0064] Step 1400: Determine the target shelf and the target layer of the target shelf according to the weight of the target raw material and the harness type of the target raw material.

[0065] Since the target raw material is the raw material used by the target production line and its weight has changed, if it is directly stored in the original position, the stability of the shelf may be reduced. For example, if the target raw material was originally stored in the lower layer of the shelf and its weight decreases after being used by the target production line, if it is still stored in the lower layer of the shelf, it will cause the situation of the upper part being heavy and the lower part being light of the shelf, making the shelf unstable.

[0066] In addition, during the process of the target production line using the target raw material, it is also possible that the original position of the target raw material is occupied by new raw materials. Therefore, it cannot be directly stored in the original position and the storage position of the target raw material in the shelf needs to be determined again.

[0067] Specifically, step 1400 includes steps 1410-1420.

[0068] Step 1410: Determine the target shelf according to the harness type of the target raw material.

[0069] The weight of the target raw material can represent the amount of the remaining harness. Since the raw material warehouse in the present invention includes multiple shelves and the types of raw materials stored in each shelf are not exactly the same. There may be a situation where some types of raw materials are only stored in some shelves, or there may be a situation where the same type of raw materials are stored in all shelves.

[0070] For example, if the harness type of the target raw material is type A and the harnesses of type A are all stored in shelves A1, A2, B1, and B2, then the target shelf is determined from shelves A1, A2, B1, and B2 and can be any one of them.

[0071] Step 1420: Determine the target layer of the target shelf according to the weight of the target raw material, where the greater the weight of the target raw material, the lower the target layer of the target shelf.

[0072] The target layer where the target raw material is stored in the target shelf is determined by the weight of the target raw material. The greater the weight, the lower the layer. Store the raw materials with greater weight in the lower layer of the shelf and the light ones in the upper layer of the shelf to improve the stability of the shelf.

[0073] In addition, the storage location of the target raw material can be determined in combination with the current storage situation of the shelves. For example, according to the wire harness type, it can be determined that the target raw material can be stored in multiple target shelves, and then the target layer is determined according to the weight of the target raw material. Then, according to whether there is available storage space in the target layers of the multiple target shelves, the target shelf where the target raw material needs to be stored is determined. If there are still multiple target shelves that can store the raw material, then it is further determined according to the distance between the multiple target shelves and the target production line, and the nearest target shelf is selected for storage.

[0074] Step 1500: Transport the target raw material to the target shelf through the first conveyor belt.

[0075] Step 1600: Remove the target raw material from the first conveyor belt through the stacker corresponding to the target shelf and store it in the target layer of the target shelf.

[0076] After determining the storage location of the target raw material, the target raw material is transported through the first conveyor belt to the target shelf. Then, the target raw material is removed from the first conveyor belt by the stacker of the target shelf and stored in the target layer of the target shelf. Each layer of the shelf is divided into multiple spaces for storing raw materials, and the target raw material can be stored in any space.

[0077] The beneficial effects of the present invention are as follows: By determining the target shelf and the target layer of the target shelf according to the weight of the target raw material and the wire harness type of the target raw material, the present invention finds a suitable storage location for the reuse of the target raw material, thereby improving efficiency.

[0078] In this embodiment, the method further includes steps 2100-2200.

[0079] Step 2100: When it is detected that there is a raw material barrel removed from the target production line in the dock area of the target production line, control the first area of the first conveyor belt corresponding to the dock area of the target production line to stop running, and the first area is the reverse area along the running direction of the first conveyor belt at the connection position between the target production line and the first conveyor belt.

[0080] Step 2200: After emptying the dock area of the target production line, control the first area of the first conveyor belt to continue running.

[0081] During the process of re-storing the target raw material that has been used on the target production line into the shelf, the target raw material will pass through the dock area of the target production line and be weighed in the dock area. When there is raw material in the dock area, it is necessary to prioritize clearing the dock area. On the one hand, it ensures timely feeding of the production line, and on the other hand, it ensures that the raw materials used on the production line can be removed from the production line in a timely manner to avoid congestion.

[0082] In order to empty the dock area of the target production line, when there is raw material in the dock area of the target production line, the first area of the first conveyor belt corresponding to the dock area of the target production line is stopped from running. After the first area stops running, the raw materials being transported on the first conveyor belt cannot reach the connection position between the target production line and the first conveyor belt, which can ensure that when emptying the dock area of the target production line, the raw materials in the dock area of the target production line will not be blocked by other raw materials and can be quickly emptied.

[0083] The conveyor belt in the present invention is a conveyor belt in the form of guide rails, which is composed of multiple guide rails arranged. Each guide rail rotates around its own axis in place to drive the raw materials to run. The control system can control any guide rail to stop running.

[0084] The size of the first area can be determined according to the distribution of raw materials on the first conveyor belt. If the number of raw materials on the first conveyor belt is small, then only a small number of guide rails need to be controlled to stop, and the first area is small. If the number of raw materials on the first conveyor belt is large, in order to avoid a large amount of raw materials concentrating in a small area, at this time, the number of guide rails that stop running can be appropriately increased, and the first area is large.

[0085] As Figure 1 shown, taking production line 2 as an example for illustration below, the first conveyor belt runs in the direction shown by the dotted line in Figure 1 . The part of the first conveyor belt close to the production line runs in the direction from top to bottom. Here, top and bottom are not the actual directions, but the directions in Figure 1 . The first area of the first conveyor belt corresponding to the dock area of production line 2 is the area of the first conveyor belt above the dock area of production line 2 in Figure 1 .

[0086] In this embodiment, a third conveyor belt is provided at the position of the first conveyor belt close to the warehouse entrance and exit. The method further includes: when there is a new raw material placed on the third conveyor belt, determining the warehouse corresponding to the new raw material according to the wire harness type of the new raw material; transporting the new raw material to the first conveyor belt through the third conveyor belt, and transporting the new raw material to the warehouse corresponding to the new raw material for storage through the first conveyor belt.

[0087] As Figure 1 shown, a conveyor belt 3 is provided at the entrance and exit position of the raw material warehouse. When external raw materials need to be stored in the warehouse, the external raw materials can be placed on conveyor belt 3, transported to conveyor belt 2 through conveyor belt 3, then picked up by the stacker, and then the raw materials are put into the shelf by the stacker.

[0088] The new raw materials are transported to conveyor belt 1 via conveyor belt 3, and then transported to the corresponding warehouse via conveyor belt 1. The new raw materials will not be directly supplied to the production line. Even if the production line has a material requirement during the process of the new raw materials being stored in the warehouse, the new raw materials need to be stored in the warehouse before being supplied to the production line. By this means, the usage of all raw materials can be recorded to avoid omission and facilitate the management of the feeding system.

[0089] In this embodiment, determining the warehouse corresponding to the new raw materials according to the harness type of the new raw materials includes: determining the usage frequency according to the harness type of the new raw materials; determining the warehouse corresponding to the new raw materials according to the usage frequency, wherein the higher the usage frequency, the closer the warehouse corresponding to the new raw materials is to the production line.

[0090] Automobile harness manufacturers will produce various types of automobile harnesses, and the harness types of the raw materials required for producing different types of automobile harnesses are different, and the usage frequencies of the raw materials of different harness types are also different. For the raw materials with high usage frequency, they are placed in the warehouse close to the production line, and for the raw materials with low usage frequency, they are placed in the warehouse far from the production line. By this means, the overall transportation time of the raw materials can be reduced and the efficiency can be improved.

[0091] In this embodiment, a second conveyor belt is provided at the middle position of the first conveyor belt. After determining the target shelf and the target layer of the target shelf, the method further includes steps 3100 - 3200.

[0092] Step 3100: Determine the transportation route of the target raw materials according to the position of the dock area of the target production line and the position of the target shelf.

[0093] Step 3200: Transport the target raw materials to the target shelf according to the transportation route of the target raw materials.

[0094] As Figure 1 shown, the second conveyor belt is conveyor belt 2. Conveyor belt 1 is a circular conveyor belt arranged around the raw material warehouse, and conveyor belt 2 is provided in the middle of conveyor belt 1. Then there can be multiple routes for raw material transportation during the raw material transportation process.

[0095] For example, if it is necessary to transport the raw materials in the dock area of production line 1 to shelf A1, the raw materials can be transported to the area above shelf A1 via conveyor belt 1, and then the raw materials are taken from conveyor belt 1 by stacker 1 and stored in shelf A1. It is also possible to transport the raw materials to the intersection position of conveyor belt 1 and conveyor belt 2 in the lower left of shelf A1 via conveyor belt 1, and then transport the raw materials to the area below shelf A1 via conveyor belt 2, and then take the raw materials from conveyor belt 2 by stacker 1 and store them in shelf A1.

[0096] Different transportation routes will result in different transportation durations, which affect production efficiency. Select the transportation route with the shortest transportation duration based on the location of the dock area of the target production line and the location of the target shelf to improve production efficiency.

[0097] In this embodiment, step 3100 includes steps 3110 - 3130.

[0098] Step 3110: Calculate the first length of the first transportation route for transporting the target raw material to the target shelf through the first conveyor belt.

[0099] Step 3120: Calculate the second length of the second transportation route for transporting the target raw material to the target shelf through the first conveyor belt and the second conveyor belt.

[0100] Step 3130: Determine the transportation route of the target raw material according to the first length and the second length.

[0101] First, determine the first transportation route and the second transportation route according to the location of the dock area of the target production line and the location of the target shelf. The first transportation route is the transportation route that only includes the first conveyor belt. The second transportation route is the transportation route that includes both the first conveyor belt and the second conveyor belt.

[0102] Then calculate the first length of the first transportation route and the second length of the second transportation route. If the first length is greater than the second length, then use the second transportation route as the transportation route for transporting the target raw material. If the first length is less than the second length, then use the first transportation route as the transportation route for transporting the target raw material.

[0103] In this embodiment, when the transportation route of the target raw material includes the first conveyor belt and the second conveyor belt, the method further includes:

[0104] When the target raw material reaches the intersection position of the first conveyor belt and the second conveyor belt, obtain the congestion situation of the first conveyor belt and the congestion situation of the second conveyor belt;

[0105] When the congestion situation of the first conveyor belt is more serious, control the target raw material to be transported along the second conveyor belt;

[0106] When the congestion situation of the second conveyor belt is more serious, control the target raw material to be transported along the first conveyor belt. [[ID=3)2]]

[0107] The conveyor belt in this application is composed of multiple guide rails arranged in a row. The two ends of the guide rails are fixed along the axial direction and can rotate around the axis. The axial direction of the guide rails is perpendicular to the running direction of the conveyor belt. The rotation of the guide rails drives the raw materials on the conveyor belt to move. Since it is possible to control some of the guide rails in the conveyor belt to stop while allowing the guide rails in other areas to operate, congestion may occur on the conveyor belt.

[0108] If the second transportation route is selected as the transportation route for the target raw materials, then during transportation, it will pass through the intersection position of the first conveyor belt and the second conveyor belt. When the raw materials are transported to the intersection position of the two conveyor belts, the transportation route is further selected according to the congestion situation to avoid causing greater congestion.

[0109] This embodiment introduces a device applying the method for controlling the return of materials in an automotive wire harness production line according to any one of the embodiments of the present invention, including:

[0110] A first control module, configured to place the target raw materials on the conveyor belt of the target production line after the target raw materials are used up in the target production line;
