Description

Technical Field

[0001] This application belongs to the field of sorting production line technology, and in particular relates to a sorting method, electronic equipment and computer-readable storage medium. Background Technology

[0002] Different grades of battery cells have different parameters such as charge storage capacity, internal resistance characteristics, and cycle life. Generally, cells of the same grade need to be assembled to ensure that each assembled battery module has similar performance characteristics and improve the stability of the battery module.

[0003] Currently, unqualified battery cells are typically removed using sorting equipment, and cells of different grades are grouped together. With existing sorting equipment, each grade of battery cell flows into a separate sorting line and is packaged at the corresponding tray assembly station.

[0004] When the incoming materials contain a large number of different grades of battery cells, using a specific grade for each cell grade in the assembly station would result in a bulky, space-consuming, and costly system. Furthermore, the quantity of some grades of battery cells in the incoming materials might be relatively small, leading to underutilization of the capacity of their corresponding assembly stations. Summary of the Invention

[0005] This application provides a sorting method, electronic device, and computer-readable storage medium to solve the technical problems of insufficient capacity of some tray assembly stations due to the large number of tray assembly stations in existing sorting equipment, and the large space occupied and high cost of the entire sorting equipment.

[0006] According to one aspect of this application, a sorting method is provided, comprising:

[0007] According to the preset screening rules, first-class materials and second-class materials are determined from the mixed incoming materials, wherein the proportion of each grade of materials in the first-class materials is greater than the proportion of each grade of materials in the second-class materials.

[0008] Each grade of material in the first category is assigned to the corresponding target sorting channel in the sorting line for sorting. The sorting line includes multiple tray assembly stations, and each tray assembly station is connected to at least one sorting channel.

[0009] Each grade of material in the second category is assigned to a cache station in the cache line for caching.

[0010] In an optional embodiment of this application, according to preset screening rules, first-class materials and second-class materials are determined from the mixed incoming materials, including:

[0011] Obtain the quantity of each grade of material in the mixed incoming material;

[0012] Calculate the proportion of each grade of material in the mixed incoming material based on the quantity of each grade of material in the mixed incoming material;

[0013] According to the preset screening rules, the N grades of materials that account for the largest proportion in the mixed incoming materials are identified as the first grade materials, and the other grades of materials in the mixed incoming materials other than the first grade materials are identified as the second grade materials. The number of tray assembly stations is the same as the number of grades of the first grade materials, and N is a positive integer.

[0014] In an optional scheme of this application, each grade of material in the first category is assigned to the corresponding target sorting channel in the sorting line for sorting, including:

[0015] For any grade of material in the first category, the target palletization efficiency Q of the grade of material is determined based on the percentage of grade material S% and the total palletization efficiency W.

[0016] Based on the preset sorting rules and target tray efficiency, the target sorting channel for graded materials is determined from all sorting channels in the sorting line;

[0017] Materials are sorted according to grade based on each target sorting channel.

[0018] In the optional scheme of this application, all sorting channels in the sorting line include multiple main sorting channels and multiple backup sorting channels. Based on preset sorting rules and target tray efficiency, the target sorting channel for the graded materials is determined from the multiple sorting channels, including:

[0019] According to the first preset sorting rule in the preset sorting rules, the target main sorting channel for graded materials is determined from multiple main sorting channels. The first preset sorting rule includes at least the relationship between the grade of each graded material and the main sorting channel.

[0020] When the tray assembly efficiency Q1 of the target main sorting channel is less than the target tray assembly efficiency Q, the target backup sorting channel for the grade material is determined from multiple backup sorting channels according to the second preset sorting rule in the preset sorting rules, the tray assembly efficiency Q1 of the target main sorting channel, and the target tray assembly efficiency Q. The second preset sorting rule includes at least the positional relationship between the main sorting channel and the backup sorting channel for each grade material.

[0021] In the optional scheme of this application, the target master sorting channels of any two grades of materials in the first category are different.

[0022] In an optional scheme of this application, when the tray assembly efficiency Q1 of the target main sorting channel is less than the target tray assembly efficiency Q, the target backup sorting channel for the graded material is determined from multiple backup sorting channels according to the second preset rule in the preset sorting rules, the tray assembly efficiency Q1 of the target main sorting channel, and the target tray assembly efficiency Q. This includes:

[0023] Based on the tray assembly efficiency Q1 of the target master sorting channel and the target tray assembly efficiency Q, determine the total efficiency Q2 of the spare sorting channel;

[0024] Identify all available backup sorting channels from multiple backup sorting channels;

[0025] Based on the total efficiency Q2 of the spare sorting channels and the tray assembly efficiency (q1, q2, ..., q) of each spare sorting channel in an idle state. n And the second preset sorting rule, determine the target backup sorting channel from the backup sorting channels that are in an idle state, where q1, q2, ..., q n These are the tray assembly efficiencies for a single spare sorting channel when it is in an idle state, where n is a positive integer.

[0026] In the optional scheme of this application, based on the total efficiency Q2 of the spare sorting channels and the tray assembly efficiency (q1, q2, ..., q) of each spare sorting channel in the idle state, n And a second preset rule, determining the target backup sorting channel from the backup sorting channels that are in an idle state, including:

[0027] Calculate the overall efficiency q of all standby sorting channels in idle state. 总 = q1 + q2 + ... + q n ;

[0028] In Q2≤q 总 In the case of [the situation], according to the second preset sorting rule, the target backup sorting channel is determined from the backup sorting channels that are in an idle state;

[0029] In Q2>q 总 In the case of idle status, all spare sorting channels are designated as target spare sorting channels for graded materials, and graded materials exceeding the capacity of all target spare sorting channels are allocated to the buffer station in the buffer line for buffering.

[0030] In the optional schemes of this application, the sorting method also includes:

[0031] Based on the target tray assembly station corresponding to each target sorting channel, graded materials are trayed.

[0032] In the optional scheme of this application, multiple sorting channels at each tray assembly station are used to transport materials of different grades. Based on the target tray assembly station corresponding to each target sorting channel, the graded materials are trayed, including:

[0033] For any target tray assembly station, if it is determined that the target tray assembly station only receives graded materials conveyed by the target sorting channel, the graded materials conveyed by the target sorting channel are trayed with the first tray assembly efficiency.

[0034] If the target tray assembly station receives graded materials from the target sorting channel and other sorting channels, the graded materials transmitted from the target sorting channel are trayed at the second tray assembly efficiency, and the second tray assembly efficiency is less than the first tray assembly efficiency.

[0035] In the optional scheme of this application, each tray assembly station is connected to two sorting channels, one of which is the main sorting channel and the other is the backup sorting channel; or both sorting channels are main sorting channels, one of which is used to transport the grade material with the largest proportion in the first grade material, and the other is used to transport the grade material with the smallest proportion in the first grade material.

[0036] In the optional schemes of this application, the sorting method also includes:

[0037] Calculate the remaining capacity D of all target sorting channels for materials of the current conveying class;

[0038] If the current quantity E of grade material in F consecutive incoming mixed materials is greater than the remaining capacity D, the grade material of quantity ED is sent to the buffer station for buffering, where F < G, and G is the total quantity of material in the mixed incoming materials.

[0039] In an optional embodiment of this application, all sorting channels in the sorting line also include a mixed sorting channel, and the sorting method further includes:

[0040] For any type of material in the cache station, determine whether the quantity of the material of that type meets the preset requirements;

[0041] If the graded materials meet the preset requirements, the graded materials are transported to the mixed sorting channel connected to the buffer station.

[0042] Based on the target traying station corresponding to the mixed sorting channel, graded materials are trayed.

[0043] According to another aspect of this application, an electronic device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the computer program, when executed by the processor, implements the sorting method described above.

[0044] According to another aspect of this application, a computer-readable storage medium is provided that stores a computer program, which, when executed by a processor, implements the sorting method described above.

[0045] In summary, the sorting method, electronic device, and computer-readable storage medium provided in this application have at least the following advantages:

[0046] Beneficial effects:

[0047] This sorting method enables the relatively high proportion of first-grade materials to fully utilize the capacity of each tray assembly station in the sorting line, while the relatively low proportion of second-grade materials can be buffered at the buffer station and assembled when the shared tray assembly station in the sorting line is idle, thereby further utilizing the capacity of the tray assembly station and ensuring sorting efficiency.

[0048] Since this sorting method enables the second-class materials to share a common tray assembly station, it can reduce the number of tray assembly stations and sorting channels, thereby reducing equipment costs and space requirements. Attached Figure Description

[0065] Figure 1 This is a structural block diagram of a sorting device 1000 according to one embodiment of this application. Please refer to... Figure 1The sorting device 1000 includes a buffer line 100, a sorting line 200, and a control system 300.

[0066] The sorting equipment 1000 can be used to sort mixed materials composed of various grades. The materials here can be battery cells, but are not limited to them. For example, they can also be battery modules, solar panels, etc.

[0067] The mixed incoming material can pass through the sorting line 200 and the buffer line 100 to separate materials of various grades within the mixed incoming material. In addition, the control system 300 is used to control the operation of the sorting line 200 and the buffer line 100 to achieve sorting logic control.

[0068] The control system 300 can be a distributed control system, which generally includes a host computer and a controller module. The host computer can be, for example, a personal computer or an industrial computer, which is responsible for monitoring and controlling the entire sorting process. The controller module can be, for example, a programmable logic controller (PLC) or a combination of multiple distributed control units, which is responsible for real-time control and execution logic.

[0069] Figure 2 This is a partial schematic diagram of a sorting device 1000 provided according to one embodiment of this application; Figure 3 This is a partial schematic diagram of a sorting device 1000 according to another embodiment of this application. It should be noted that... Figure 2 and Figure 3 Only the functional components of the sorting equipment used to achieve sorting and tray assembly were shown, and... Figure 2 and Figure 3 The difference lies in the different layout of the sorting channel 230.

[0070] Please see Figure 2 and Figure 3 The sorting equipment 1000 also includes a front sorting disc station 400, and the front sorting disc station 400, the sorting line 200, and the buffer line 100 are connected sequentially in the conveying direction of the mixed material. In other words, the mixed material can pass through the front sorting disc station 400, the sorting line 200, and the buffer line 100 sequentially.

[0071] The sorting line 200 includes multiple pre-selected sorting tray stations 210 and multiple grouping tray stations 220, and the buffer line 100 includes a buffer station 110 and a mixed sorting tray station 120.

[0072] The number of predetermined sorting disc stations 210 is equal to the number of tray assembly stations 220. Multiple predetermined sorting disc stations 210 are connected sequentially in the conveying direction of the mixed incoming material, and multiple tray assembly stations 220 are independent of each other. Each predetermined sorting disc station 210 and each tray assembly station 220 are connected one-to-one through at least one sorting channel 230.

[0073] The mixing and sorting tray station 120 is connected to the downstream predetermined sorting tray station 210 of the sorting line 200, and is connected to the downstream tray assembly station 220 of the sorting line 200 through at least one sorting channel 230. Furthermore, the buffer station 110, together with the mixing and sorting tray station 120, forms a circulation loop, allowing graded materials entering the buffer station 110 to circulate within the loop.

[0074] It should be noted that all grades of materials in the mixed incoming materials are labeled, and different grades of materials correspond to different labels. These labels may include, for example, QR codes, barcodes, electronic tags, and sensors.

[0075] As can be seen from the above, the sorting disc station includes a front sorting disc station 400, a pre-sorting disc station 210, and a mixed sorting disc station 120, all of which are equipped with an identification module. The identification module is used to identify the markings on graded materials.

[0076] In practical applications, the pre-sorting station 400 can identify and sort qualified grade materials to ensure that the various grades of materials conveyed to the sorting line 200 and the buffer line 100 are qualified. The pre-sorting station 210 has been configured with the grade of the materials to be identified and sorted.

[0077] The buffer station 110 is used to buffer the graded materials. Since the various grades of materials in the buffer station 110 will circulate in the loop, they will pass through the mixing and sorting plate station 120. The mixing and sorting plate station 120 is used to identify and sort out the various grades of materials buffered in the buffer station 110.

[0078] Understandably, the graded materials sorted out at the sorting tray station can be transported through the corresponding sorting channel 230 to the corresponding tray assembly station 220 for tray assembly.

[0079] In addition, the sorting station can use a rotary sorting machine, and the rotary sorting machine can use identification modules such as radio frequency identification (RFID), NFC (Near Field Communication), industrial cameras, barcode scanners, etc.

[0080] In one optional embodiment, the sorting disc station also includes a counting module to count the quantity of sorted graded materials. Specifically, the rotary sorter may use, for example, a photoelectric counter or a vibration counter as the counting module.

[0081] In another alternative embodiment, the quantity of graded materials sorted by the sorting disc station can be directly counted by the control system 300.

[0082] The palletizing station 220 can be a palletizing machine, which includes a conveying device and a carrier channel. The carrier channel is used to transport packaging containers for graded materials, and the conveying device is used to transfer the graded materials from the sorting channel 230 into the packaging containers, which can be cartons, etc. Understandably, the capacity of the packaging container is the number of pallets assembled in a single operation.

[0083] In practical applications, the handling device can be, for example, a multi-degree-of-freedom handling robotic arm or a gripper device with multiple degrees of freedom of movement. The carrier channel and sorting channel 230 can be, for example, a belt conveyor or a roller conveyor. The buffer station 110 can be a buffer tower or a conveyor channel of a certain length to accommodate a certain quantity of materials.

[0084] exist Figure 2 and Figure 3 In the illustrated embodiment, there are four predetermined sorting tray stations 210 and four tray assembly stations 220. The three upstream predetermined sorting tray stations 210 and the three upstream tray assembly stations 220 are connected one-to-one by two sorting channels 230. The downstream predetermined sorting tray station 210 and the downstream tray assembly station 220 are connected by one sorting channel 230. The mixing sorting tray station 120 is connected to the downstream tray assembly station 220 via one sorting channel 230.

[0085] It should be noted that the sorting equipment 1000 is not limited to the illustrated embodiment. The predetermined sorting disc station 210, the mixing sorting disc station 120, and the tray assembly station 220 can be adjusted according to the number of grades of materials in the mixed incoming material. Correspondingly, the number of sorting channels 230 can also be adaptively adjusted according to the number of predetermined sorting disc stations 210, the mixing sorting disc station 120, and the tray assembly station 220.

[0086] This application provides a sorting method that can be applied to, for example... Figure 1 , Figure 2 and Figure 3 The sorting equipment shown. Figure 4 This is a schematic flowchart illustrating a sorting method according to one embodiment of this application. Please refer to... Figure 4The sorting method may include, but is not limited to, the following steps:

[0087] S41, according to the preset screening rules, determine the first-class material and the second-class material from the mixed incoming materials, wherein the proportion of each grade of material in the first-class material is greater than the proportion of each grade of material in the second-class material.

[0088] S42, each grade of material in the first category is assigned to the corresponding target sorting channel in the sorting line 200 for sorting. The sorting line 200 includes multiple tray assembly stations 220, and each tray assembly station 220 is connected to at least one sorting channel 230.

[0089] S43, allocate each grade of material in the second category to the cache station 110 in the cache line 100 for caching.

[0090] For S41, the preset screening rule here refers to determining whether a material belongs to Category 1 or Category 2 based on the proportion of its grade. This proportion is the ratio of the quantity of a grade to the total quantity of all grades. The proportion of any grade within Category 1 is greater than the proportion of any grade within Category 2. In other words, the proportion of the least abundant grade within Category 1 is greater than the proportion of the most abundant grade within Category 2.

[0091] For S42, the first grade of material is assigned to sorting line 200 for sorting. It should be understood that, to achieve the sorting objective, the sorting channel 230 corresponding to each grade of material should be different, and the sorting channel 230 corresponding to each grade of material is the target sorting channel.

[0092] Please combine Figure 2 and Figure 3 In the embodiment shown, each predetermined sorting tray station 210 in the sorting line 200 has been pre-configured to sort the corresponding grade materials in the first category of materials. During the process of the mixed incoming materials passing through the sorting line 200, the various grades of materials in the first category of materials are sorted out by the corresponding predetermined sorting tray stations 210 and enter the corresponding sorting channel 230 (target tray assembly channel) to be transported to the corresponding tray assembly station 220 for tray assembly.

[0093] As can be seen, sorting here refers to the allocation of various grades of materials in the first category of materials to the corresponding sorting channels 230 through the predetermined sorting tray station 210. That is, each grade of material is sorted through the corresponding sorting channel 230 and transported to the corresponding tray assembly station 220.

[0094] For S43, the second-grade material is assigned to buffer line 100 to await sorting. Specifically, the second-grade material is first assigned to buffer station 110 for buffering to await sorting.

[0095] Please combine Figure 2 and Figure 3 In the embodiment shown, the buffer line 100 shares the downstream tray assembly station 220 of the sorting line 200. If the quantity of graded materials in the buffer station 110 meets the sorting conditions, the graded materials can be sorted out by the mixing sorting tray station 120 and transported to the downstream tray assembly station 220 via the corresponding sorting channel 230 for tray assembly.

[0096] As can be seen, various grades of materials in the second category can share the tray assembly station 220 in the sorting line 200 through the sorting channel 230. This can greatly reduce the number of sorting channels 230 and the number of tray assembly stations 220, thereby reducing equipment costs and space occupation.

[0097] In practical applications, the first-grade materials, which account for a relatively high proportion, can fully utilize the capacity of each tray assembly station 220 in the sorting line 200, while the second-grade materials, which account for a relatively low proportion, can be cached at the buffer station 110 and assembled when the tray assembly station 220 shared by the sorting line 200 is idle, so as to further utilize the capacity of the tray assembly station 220 and ensure sorting efficiency.

[0098] It should be understood that, since this sorting method enables the second-class materials to share the same tray assembly station 220, the number of tray assembly stations 220 and the number of sorting channels 230 can be reduced accordingly, thereby reducing equipment costs and space requirements.

[0099] In a further optional embodiment, in S41, determining the first-class material and the second-class material from the mixed incoming materials according to a preset screening rule may include:

[0100] Obtain the quantity of each grade of material in the mixed incoming material;

[0101] Calculate the proportion of each grade of material in the mixed incoming material based on the quantity of each grade of material in the mixed incoming material;

[0102] According to the preset screening rules, the N grades of materials that account for the largest proportion in the mixed incoming materials are identified as the first grade materials, and the other grades of materials in the mixed incoming materials other than the first grade materials are identified as the second grade materials. The number of tray assembly stations 220 is consistent with the number of grades of the first grade materials, and N is a positive integer.

[0103] In this embodiment, the control system 300 can count the quantity of each grade of material entering the sorting line 200 and calculate the proportion of each grade of material. Specifically, please refer to... Figure 2 and Figure 3 In the illustrated embodiment, materials of various grades entering the sorting line 200 must first pass through the pre-sorting tray station 400. In specific applications, the control system 300 can acquire and store the identification information obtained by the pre-sorting tray station 400 to count the quantity of materials of various grades entering the sorting line 200, thereby determining the proportion of each grade of material.

[0104] It should be understood that the control system 300 only needs to statistically analyze the stored identification information data to determine the proportion of each grade of material entering the sorting line 200.

[0105] The screening rule here refers to selecting the N grades of materials with the highest proportion from the mixed incoming materials as the first grade materials, and correspondingly, the remaining grades of materials are selected as the second grade materials.

[0106] For example, the mixed incoming materials contain M grades of materials, where M is greater than N and is an integer. N grades are classified as first-class materials, and MN grades are classified as second-class materials. These N grades represent the N grades of materials that constitute the largest proportion of the mixed incoming materials.

[0107] Furthermore, the number of palletizing stations 220 is equal to the number of grades of the first-class material, that is, the number of palletizing stations 220 is N. It should be noted that the number of palletizing stations 220 being equal to the number of grades of the first-class material is a preferred embodiment, thus ensuring that each grade of the first-class material can be palletized using the palletizing efficiency of at least one palletizing station 220.

[0108] In some cases, the grade of material with a high proportion in the mixed incoming materials is concentrated in a relatively large area. This results in the number of grades of the first type of material being less than the number of palletizing stations 220, i.e., N is less than the number of palletizing stations 220. In other words, some grades of material can be palletized using the sum of the palletizing efficiencies of multiple palletizing stations 220. In other words, the number of palletizing stations 220 is not less than the weight of the first type of material.

[0109] In a further optional embodiment, in S42, assigning each grade of material in the first category to the corresponding target sorting channel in the sorting line 200 may include:

[0110] For any grade of material in the first category, the target palletization efficiency Q of the grade of material is determined based on the percentage of grade material S% and the total palletization efficiency W.

[0111] Based on the preset sorting rules and target tray efficiency, the target sorting channel for graded materials is determined from the sorting channel 230 in the sorting line 200.

[0112] Materials are sorted according to grade based on each target sorting channel.

[0113] It should be understood that the overall palletizing efficiency W is the sum of the palletizing efficiencies of all palletizing stations 220, and the target overall palletizing efficiency Q for a given grade of material is the product of the proportion of that grade of material and the overall palletizing efficiency, i.e., Q = S% * W. It should be noted that the palletizing efficiency of palletizing station 220 refers to the rated palletizing efficiency of palletizing station 220, which is known.

[0114] In practical applications, the control system 300 is configured with preset sorting rules. The sorting channel 230 assigned to any grade of material in the first category of materials, i.e. the target sorting channel, is mainly determined by the target tray efficiency and the preset sorting rules.

[0115] After determining each target sorting channel corresponding to the material of that grade, it can be assigned to the target sorting channel through the corresponding predetermined sorting plate station 210, so that the material of that grade can be sorted through the corresponding target sorting channel.

[0116] It should be noted that, in some optional embodiments, all sorting channels 230 in the sorting line 200 include multiple main sorting channels 231 and multiple backup sorting channels 232.

[0117] exist Figure 2 and Figure 3 In the embodiment shown, each tray workstation 220 has two sorting channels 230, one of which can be used as the main sorting channel 231 and the other can be used as a backup sorting channel 232.

[0118] In a further optional embodiment, determining the target sorting channel for graded materials from multiple sorting channels 230 based on preset sorting rules and target tray efficiency may include:

[0119] According to the first preset sorting rule in the preset sorting rules, the target main sorting channel for graded materials is determined from multiple main sorting channels 231. The first preset sorting rule includes at least the relationship between the grade of each graded material and the main sorting channel 231.

[0120] When the tray assembly efficiency Q1 of the target main sorting channel is less than the target tray assembly efficiency Q, the target backup sorting channel for the grade material is determined from multiple backup sorting channels 232 according to the second preset sorting rule in the preset sorting rules, the tray assembly efficiency Q1 of the target main sorting channel, and the target tray assembly efficiency Q. The second preset sorting rule includes at least the positional relationship between the main sorting channel 231 and the backup sorting channel 232 for each grade material.

[0121] In this embodiment, the preset sorting rules include a first preset sorting rule and a second preset sorting rule. The first preset sorting rule is the correspondence between the grade of each grade of material in the first category and each main sorting channel 231.

[0122] In practical applications, the target master sorting channels for any two grades of materials in the first category are different. In other words, for the first category of materials, the master sorting channels 231 corresponding to different grades are different.

[0123] In one optional embodiment, a correspondence scheme of one level to one master sorting channel 231 can be adopted. Figure 2 In the embodiment shown, the sorting line 200 in the sorting equipment 1000 can sort the top four grades of materials with the highest proportion in the mixed incoming materials. Each grade of the top four grades of materials corresponds to a main sorting channel 231 in each tray station 220, that is, one grade is assigned to one main sorting channel 231.

[0124] The second preset sorting rule has the positional relationship between the main sorting channel 231 and the backup sorting channel 232 of any grade of material in the first category. The main sorting channel 231 of the grade material is the target main sorting channel assigned to that grade material.

[0125] It should be understood that, given the known layout of various workstations and sorting channels 230 in the sorting equipment 1000, preset sorting rules can be configured in the control system 300, namely, deploying the first preset sorting rule and the second preset sorting rule.

[0126] As can be seen from the above, by using the first preset sorting rule, the main sorting channel 231 corresponding to any grade of material in the first category of materials can be determined, that is, the target main sorting channel of that grade of material.

[0127] It should be noted that the tray assembly efficiency of each tray assembly station 220 is known, specifically the rated tray assembly efficiency. The tray assembly efficiency of the sorting channel 230 connected to it can be determined by the tray assembly efficiency of each tray assembly station 220, that is, the tray assembly efficiency Q1 of the target master sorting channel that can obtain graded materials.

[0128] When Q1 is less than Q, it is determined that simply opening the target main sorting channel is insufficient to meet the target tray efficiency requirements for this grade of material, thus requiring the opening of an additional backup sorting channel. The determination of the backup sorting channel is primarily based on the second preset sorting rule, the tray efficiency Q1 of the target main sorting channel, and the target tray efficiency Q. It should be understood that the backup sorting channel 232 allocated to any grade of material within the first category is the target backup sorting channel for that grade of material.

[0129] In a further optional embodiment, when the tray assembly efficiency Q1 of the target main sorting channel is less than the target tray assembly efficiency Q, the target backup sorting channel for the graded material is determined from multiple backup sorting channels 232 according to the second preset sorting rule in the preset sorting rules, the tray assembly efficiency Q1 of the target main sorting channel, and the target tray assembly efficiency Q. This may include:

[0130] Based on the tray assembly efficiency Q1 of the target master sorting channel and the target tray assembly efficiency Q, determine the total efficiency Q2 of the spare sorting channel;

[0131] Identify all available backup sorting channels 232 from multiple backup sorting channels;

[0132] Based on the total efficiency Q2 of the spare sorting channels and the tray assembly efficiency (q1, q2, ..., q) of each spare sorting channel 232 in an idle state. n And the second preset rule, determine the target sorting channel from the idle backup sorting channels 232, where q1, q2, ..., q n These are the disk assembly efficiencies of a single spare sorting channel 232 when it is in an idle state, where n is a positive integer.

[0133] In this embodiment, it is determined that it is difficult to meet the target tray efficiency Q when sorting is performed only through the target master sorting channel. Therefore, it is necessary to enable the backup sorting channel, and the total efficiency of the backup sorting channel is Q2, where Q2 = Q - Q1. That is, the total efficiency Q2 of the backup sorting channel is the difference between the target tray efficiency Q and the tray efficiency Q1 of the target master sorting channel.

[0134] It should be understood that the spare sorting channel 232 can only be used when it is idle. In other words, the spare sorting channel 232 in an idle state refers to a spare sorting channel 232 that is not occupied. Specifically, the spare sorting channel 232 is connected to the tray assembly station 220 and the predetermined sorting tray station 210. Whether the spare sorting channel 232 connected to it is idle can be determined according to the operation status of the tray assembly station 220, or according to the operation status of the predetermined sorting tray station 210.

[0135] Understandably, the tray assembly efficiency of each idle standby sorting channel 232 is mainly determined by the tray assembly efficiency of other occupied sorting channels 230 connected to the same tray assembly station 220. Specifically, the idle standby sorting channel 230 is the difference between the tray assembly efficiency of the tray assembly station 220 and the tray assembly efficiency of the occupied sorting channel 230.

[0136] Furthermore, having determined the tray assembly efficiency of each spare sorting channel in the idle state, the required number of idle spare sorting channels can be determined to ensure, as much as possible, the overall efficiency Q2 of the spare sorting channels is met. Moreover, according to the second preset sorting rule, the spare sorting channel 232 that satisfies the positional relationship condition and is in the idle state is the target spare sorting channel.

[0137] In a further optional embodiment, based on the total efficiency Q2 of the spare sorting channels and the tray assembly efficiency (q1, q2, ..., q) of each spare sorting channel 232 in the idle state, n The second preset rule, which determines the target sorting channel from the idle backup sorting channels 232, may include:

[0138] Calculate the overall efficiency q of all standby sorting channels 232 in idle state. 总 = q1 + q2 + ... + q n ;

[0139] In Q2≤q 总 In the case of the second preset sorting rule, the target backup sorting channel is determined from the backup sorting channel 232 that is in an idle state;

[0140] In Q2>q 总 In the case of idle status, all standby sorting channels 232 are identified as target standby sorting channels for the grade of material, and grade materials exceeding the capacity of all target standby sorting channels are allocated to the cache station 110 in the cache line 100 for caching.

[0141] Understandably, the amount of graded materials that sorting channel 230 can hold is fixed, and the sorting channel capacity refers to the amount of graded materials that sorting channel 230 can hold. In practical applications, the amount of graded materials that sorting channel 230 can hold is the capacity of the packaging container, which is the number of trays assembled at one time.

[0142] After confirming that Q2≤q 总Under the condition that the total number of standby sorting channels 232 in the idle state is sufficient to meet the requirement of achieving the total efficiency Q2 of the standby sorting channels, the standby sorting channels 232 that meet the quantity and positional relationship and are in the idle state can be selected as the target standby sorting channels according to the second preset sorting rule.

[0143] After confirming that Q2 > q 总 Under the condition that, it indicates that the total number of spare sorting channels 232 in the idle state is insufficient, so all spare sorting channels 232 are taken as target spare sorting channels in order to get as close as possible to the total efficiency Q2 of spare sorting channels.

[0144] It should be understood that if the total number of spare sorting channels 232 in the idle state is insufficient, it indicates that the total efficiency of the spare sorting channels 232 in the idle state is insufficient to meet the demand, and thus a blockage will occur.

[0145] Furthermore, materials exceeding the capacity of the target sorting channel are transported to the buffer station 110 for buffering to avoid blockage.

[0146] In some optional embodiments, the sorting method may further include:

[0147] Based on the target tray assembly station corresponding to each target sorting channel, graded materials are trayed.

[0148] Based on the above, it can be seen that for the first category of grade materials, the target sorting channel allocated to the grade materials can be the target main sorting channel or the target main sorting channel and the target backup sorting channel.

[0149] Specifically, for the first-class materials, the proportion of one class of materials is relatively low, and the sorting rate requirement can be met by just one sorting channel 230. In this case, the sorting channel 230 is the target main sorting channel, that is, the target sorting channel is the target main sorting channel.

[0150] One type of material has a relatively high proportion, requiring multiple sorting channels 230 to meet the sorting rate requirements. One sorting channel 230 is the target main sorting channel, and the remaining sorting channels 230 are the target backup sorting channels. In other words, the target sorting channels are the target main sorting channel and the target backup sorting channel.

[0151] In a further optional embodiment, the multiple sorting channels 230 of each tray assembly station 220 are used to transport materials of different grades. In other words, each sorting channel 230 connected to the same tray assembly station 220 is assigned to a different grade of material.

[0152] Furthermore, based on the target traying station corresponding to each target sorting channel, the graded materials are trayed, which may include:

[0153] For any target tray assembly station, if it is determined that the target tray assembly station only receives graded materials transmitted by the target sorting channel, the graded materials transmitted by the target sorting channel are trayed with the first tray assembly efficiency.

[0154] If the target tray assembly station receives graded materials from the target sorting channel and other sorting channels, the graded materials transmitted from the target sorting channel are trayed at the second tray assembly efficiency, and the second tray assembly efficiency is less than the first tray assembly efficiency.

[0155] As mentioned above, for any of the first-class materials, once the target sorting channel is determined, the tray assembly station 220 corresponding to the target sorting channel is the target tray assembly station.

[0156] Assuming that the grade of material assigned to each sorting channel 230 on the same tray assembly station 220 is different, and that the target tray assembly station only receives material of the grade conveyed by the target sorting channel (i.e., only one of the multiple sorting channels 230 corresponding to the target tray assembly station is occupied), and that occupied sorting channel 230 is the target sorting channel), then the target tray assembly station is only for one grade of material. Accordingly, the grade of material conveyed by the target sorting channel can be sorted at the first tray assembly efficiency, and the first tray assembly efficiency can even be the tray assembly efficiency of the target tray assembly station.

[0157] When it is determined that the target tray station receives graded materials conveyed by the target sorting channel and other sorting channels, that is, at least two of the sorting channels 230 corresponding to the target tray station are occupied, since the graded materials sorted by the occupied sorting channels 230 are different, it indicates that at least two grades of materials share the target tray station.

[0158] Since the tray assembly efficiency of the target tray assembly station is fixed, and the tray assembly efficiency of the target tray assembly station is occupied by at least two grades of materials, the grade of materials transported in the target sorting channel can only be conveyed at the second tray assembly efficiency, which is less than the efficiency of the first tray assembly.

[0159] Please see Figure 2 Each tray workstation 220 is connected to two sorting channels 230, one of which is the main sorting channel 231 and the other is the backup sorting channel 232.

[0160] In this embodiment, some of the tray assembly stations 220 are connected to two sorting channels 230, one of which is the main sorting channel 231 and the other is a backup sorting channel 232. For example, the target tray assembly station corresponds to two sorting channels 230. Since these two sorting channels 230 can sort materials of different grades, one is the target main sorting channel corresponding to A1 grade materials, and the other is the backup sorting channel corresponding to A2 grade materials.

[0161] In this way, it is possible to control the traying of A1 grade materials with the efficiency of the second tray group, while the traying efficiency of A2 grade materials is the difference between the traying efficiency of the target traying station and the efficiency of the second tray group.

[0162] Please see Figure 3 Both sorting channels 230 are main sorting channels 231. One main sorting channel 231 is used to transport the grade material with the largest proportion of the first grade material, and the other main sorting channel 231 is used to transport the grade material with the smallest proportion of mixed first grade material.

[0163] exist Figure 3 In the embodiment shown, the two sorting channels 230 connected to the upstream tray assembly station 220 are both main sorting channels 231, and the two sorting channels 230 connected to some tray assembly stations 220 are the main sorting channel 231 and the backup sorting channel 232, respectively.

[0164] For the two main sorting channels 231 connected to the upstream tray assembly station 220, the grade material with the largest proportion in the first grade material is sorted through one of the main sorting channels 231, and the grade material with the smallest proportion in the first grade material is sorted through the other main sorting channel 231.

[0165] In this way, the smallest and largest proportions of the first-level materials used for sorting share the same target tray station, which can reduce the risk of congestion and make better use of the capacity of the target tray station.

[0166] In some optional embodiments, the sorting method further includes:

[0167] Calculate the remaining capacity D of all target sorting channels for materials of the current conveying class;

[0168] If the current quantity E of grade material in F consecutive incoming mixed materials is greater than the remaining capacity D, the grade material of quantity ED is sent to the buffer station for buffering, where F < G, and G is the total quantity of material in the mixed incoming materials.

[0169] As mentioned above, the capacity of the sorting channel is known. Therefore, the quantity of graded materials entering the target sorting channel can be counted through the predetermined sorting tray station 210, and the quantity of graded materials that have been trayed can be determined through the target tray assembly station. The difference between the two is the remaining capacity D of the target sorting channel.

[0170] As mentioned above, the identification information of graded materials entering the sorting line 200 can be counted and stored through the pre-sorting plate station 400. This identification information can determine the grade, quantity, and order of entry of the graded materials into the sorting line 200.

[0171] Extract F consecutive grades of material from the mixed incoming materials. Determine if the current quantity E of that grade of material is greater than the remaining capacity D. If so, it indicates that the material of that grade is too concentrated among the F consecutive grades. To avoid congestion, the grade material with a quantity of D can be sent to the buffer station 110 for buffering. It should be understood that the values ​​of F and E can be set according to requirements.

[0172] In a further optional embodiment, all sorting channels 230 in the sorting line 200 also include a hybrid sorting channel 233, and the sorting method further includes:

[0173] For any type of material in the cache station 110, determine whether the quantity of the material of that type meets the preset requirements;

[0174] If the graded material meets the preset requirements, the graded material is conveyed to the mixed sorting channel 233 connected to the buffer station 110;

[0175] Based on the target traying station corresponding to the mixed sorting channel 233, graded materials are trayed.

[0176] It should be noted that the sorting channel 230 between the mixed sorting tray station 120 and the tray assembly station 220 is the mixed sorting channel 233. For all grades of materials in the buffer station 110, as long as the quantity of one grade of material meets the preset requirements, that grade of material needs to be sorted out.

[0177] Specifically, the material of this grade is sorted to the mixing and sorting channel 233 through the mixing and sorting plate station 120. The tray assembly station 220 corresponding to the mixing and sorting channel 233 is the target tray assembly station for this grade of material. The material of this grade is trayed through the target tray assembly station.

[0178] The preset requirement here is that the quantity of graded materials in the buffer station 110 reaches the sorting quantity. Specifically, this preset requirement is an integer multiple of the single pallet assembly quantity, that is, an integer multiple of the packaging container capacity. This can avoid waiting at the pallet assembly station 220 due to insufficient single pallet assembly quantity, thus ensuring pallet assembly efficiency.

[0179] exist Figure 2 and Figure 3 In the embodiment shown, the sorting channel 230 in the entire sorting equipment 1000 adopts a layout of 4 main sorting channels 231, 3 spare sorting channels 232 and 1 mixed sorting channel 233. The mixed sorting channel 233 is connected to the downstream tray assembly station 220 in the sorting line 200. The downstream tray assembly station 220 is the target tray assembly station corresponding to all grades of materials in the buffer station 110.

[0180] In summary, when the sorting method provided in this application is applied to the sorting equipment 1000, the top N grades of materials (first-class materials) with the highest proportion can be sorted and grouped by the sorting line 200. The remaining grade materials after passing through the sorting line 200 can be buffered by the buffer line 100 to wait for sorting.

[0181] The remaining graded materials after passing through sorting line 200 include at least second-grade materials, as well as excess graded materials to avoid clogging in the first-grade materials.

[0182] In this way, materials of certain grades can share the tray assembly station 220, avoiding the need for additional sorting channels 230 and tray assembly stations 220, thus reducing equipment costs and space requirements. Furthermore, the first grade of materials fully utilizes the capacity of each tray assembly station 220 in sorting line 200, while the second grade of materials, which accounts for a relatively small proportion, can wait in the buffer station 110 to be trayed when the tray assembly station 220 corresponding to the buffer line 100 is idle, thereby further utilizing the capacity of the tray assembly station 220.

[0183] Furthermore, materials of each grade in the buffer station 110 will only be sorted if they are an integer multiple of the number of trays to be assembled in a single batch, so as to avoid waiting at the tray assembly station 220 due to the inability to meet the number of trays to be assembled in a single batch.
