Description

[0001] The present application claims the benefits of and priorities to Chinese patent application No. 202410611959.2 and Titled as "sorting device", and Chinese patent application No. 202410611992.5 and Titled as "sorting device" filed with China National Intellectual Property Administration on May 16, 2024, the content of the aforementioned applications is incorporated herein by references in their entireties.TECHNICAL FIELD

[0002] Embodiments of the present application relate to, but are not limited to, a sorting device.BACKGROUND

[0003] Battery cells of different grades have different parameters such as charge storage capacity, internal resistance characteristics, and cycle life. Generally, battery 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.

[0004] Defective battery cells are removed and battery cells of different grades are grouped through a sorting device. Each grade of battery cells flows into a corresponding palletizing station through an object conveying channel, and palletizing is realized in the palletizing station.

[0005] It can be understood that the proportion of each grade of battery cells in the incoming battery cells is different, and the production capacity of each palletizing station is fixed. The quantity of a certain grade of battery cells with a high proportion exceeds the rated production capacity of the corresponding palletizing station; and the quantity of a certain grade of battery cells with a low proportion may be much lower than the rated production capacity of the corresponding palletizing station.

[0006] As a result, the production capacity of some palletizing machines is not fully utilized, leading to low production efficiency and resource waste.TECHNICAL SOLUTIONS

[0035] A sorting device for sorting battery cells includes sorting stations and palletizing stations, and each sorting station generally corresponds to one palletizing station to realize sorting and palletizing of one grade of battery cells.

The preset palletizing quantity here can be the capacity of the packaging container, i.e., the quantity for a single palletizing.

[0037] In this way, some graded objects that do not meet the quantity for a single palletizing share the shared sorting line, so as to reduce the number of sorting lines, lower the device cost and reduce the space occupied by the device. Moreover, the waiting phenomenon of palletizing stations due to not meeting the quantity for a single palletizing can be avoided, thereby making full use of the production capacity of the palletizing stations.

[0038] Other aspects can be understood after reading and understanding the drawings and detailed description.BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present application.

[0041] Fig. 1 is a structural block diagram of the first embodiment of the sorting device provided by the present application. Please refer to Fig. 1. The sorting device 1000 includes a shared sorting line module assembly 1100 and a hierarchical sorting line module assembly 1200, and the shared sorting line module assembly 1100 is connected with the hierarchical sorting line module assembly 1200.

[0042] The hierarchical sorting line module assembly 1200 is configured to receive upstream mixed incoming objects and can sort out at most N grades of graded objects from the mixed incoming objects, where the mixed incoming objects include M grades of graded objects, M is an integer and not less than N+2, and N is an integer not less than 1.

[0043] The shared sorting line module assembly 1100 is configured to receive and buffer various grades of graded objects, and can sort out any grade of graded objects with a buffered quantity reaching a preset palletizing quantity.

[0044] It should be noted that the mixed incoming objects here may include battery cells of different grades, but are not limited thereto. For example, the mixed incoming objects may also include battery modules of different grades, solar panels of different grades, etc. In other words, the sorting device 1000 is not limited to be configured to sort battery cells.

[0045] In addition, the preset palletizing quantity here may refer to the capacity of the packaging container used for loading graded objects. The capacity of the packaging container refers to the quantity of graded objects that can be accommodated, and also refers to the quantity for a single palletizing. The packaging container here may be a carton. The upstream and downstream relationships mentioned in this application are described with reference to the conveying direction of graded objects.

[0046] In the present embodiment, the sorting device 1000 at least includes a shared sorting line module assembly 1100 and a hierarchical sorting line module assembly 1200 connected to each other. Both the shared sorting line module assembly 1100 and the hierarchical sorting line module assembly 1200 are configured to sort mixed incoming objects, and the number of grades of graded objects in the mixed incoming objects is not less than 3. In other words, the sorting device 1000 can sort mixed incoming objects including at least 3 grades of graded objects.

[0047] It should be noted that the sorting device 1000 further includes a control system 1400. The control system 1400 here may be a distributed control system, specifically including a host computer and a controller module. The controller module here may be, for example, a Programmable Logic Controller (PLC), a combination of multiple decentralized control units, etc.

[0048] It can be understood that the host computer may be an industrial computer or a computer, etc., responsible for monitoring and controlling the entire sorting process, and the controller module is configured for real-time control and execution of logic. The host computer in the control system 1400 can obtain and store identification information of various grades of graded objects, and can also count the identification information to determine quantities of various grades of graded objects, thereby determining the proportion of each grade of graded objects in the mixed incoming objects.

[0049] It should be noted that various grades of graded objects are pre-configured with identifiers, and different graded objects have different identifiers. The identifiers here may refer to two-dimensional codes, bar codes, electronic tags, inductive elements, etc. set on the graded objects.

[0050] It should be understood that the sorting process is a dynamic process, and quantities of various grades of graded objects are constantly changing. Correspondingly, the identification information stored in the control system 1400 is constantly updated, so that the proportion of each grade of graded objects in the mixed incoming objects can be determined in real time.

[0051] The hierarchical sorting line module assembly 1200 can sort out at most N grades of graded objects from the mixed incoming objects. In specific applications, the hierarchical sorting line module assembly 1200 is configured to sort out the top N grades of graded objects with the highest proportions in the mixed incoming objects, and the remaining M-N grades of graded objects with relatively low proportions are conveyed to the shared sorting line module assembly 1100.

[0052] It should be noted that quantities of various grades of graded objects in the mixed incoming objects are random. It can be understood that the quantity of some graded objects may be relatively large, and the quantity of the remaining graded objects may be relatively small. In some application scenarios, the distribution of various grades of graded objects conforms to a normal distribution. The sum of the proportions of the top N grades of graded objects with the highest proportions can reach more than 90%, and the quantity of each grade of graded objects in the remaining M-N grades of graded objects may even be difficult to reach the preset palletizing quantity.

[0053] It can be understood that in the process of sorting and palletizing for any grade of graded objects among the top N grades of graded objects with the highest proportions, there will inevitably be a remainder, where the remainder is less than the preset palletizing quantity. Therefore, the graded objects with the remainder quantity can be conveyed to the shared sorting line module assembly 1100.

[0054] In this way, for all grades of graded objects in the mixed incoming objects, in the condition that the quantity of any grade of graded objects does not reach the preset palletizing quantity, the graded objects will be conveyed to the shared sorting line module assembly 1100.

[0055] It should be noted that the shared sorting line module assembly 1100 has the function of buffering graded objects. As the continuous sorting of mixed incoming objects proceeds, quantities of various grades of graded objects buffered in the shared sorting line module assembly 1100 increase. When the quantity of any grade of graded objects in the shared sorting line module assembly 1100 reaches the preset palletizing quantity, the grade of graded objects will be sorted and palletized.

[0056] It can be known from the above that the sorting device 1000 is provided with a shared sorting line module assembly 1100 for buffering various grades of graded objects that are difficult to reach the preset palletizing quantity (quantity for a single palletizing) until the quantity of any grade of graded objects in the shared sorting line module assembly 1100 reaches the preset palletizing quantity, and then the grade of graded objects is sorted and grouped.

[0057] In this way, the top N grades of graded objects with high proportions can be sorted and palletized through the hierarchical sorting line module assembly 1200, thereby making full use of the production capacity of the hierarchical sorting line module assembly 1200. The remaining graded objects after passing through the hierarchical sorting line module assembly 1200 can be buffered in the shared sorting line module assembly 1100. Some graded objects in the shared sorting line module assembly 1100 that do not reach the preset palletizing quantity wait for sorting therein, so as to avoid the situation that the production capacity of the sorting device 1000 is difficult to be fully utilized due to failure to meet the quantity for a single palletizing.

[0058] Fig. 2 is a schematic structural framework diagram of the first embodiment of the shared sorting line module assembly provided by the present application. Please refer to Fig. 2. In a further optional embodiment, the shared sorting line module assembly 1100 includes a shared buffer module 1120 and at least one shared sorting module 1110.

[0059] The shared buffer module 1120 is configured to receive various grades of graded objects. The shared sorting module 1110 can sort out any grade of graded objects in the shared buffer module 1120 with a buffered quantity reaching the preset palletizing quantity.

[0060] In the present embodiment, the shared sorting line module assembly 1100 includes a shared buffer module 1120 and a shared sorting module 1110, where the number of shared sorting modules 1110 can be determined according to the number of grades of graded objects in the mixed incoming objects. The shared sorting module 1110 has the function of sorting graded objects, and the shared buffer module 1120 has the function of buffering graded objects.

[0061] The shared sorting module 1110 generally includes an identification function unit, and the identification function unit in the shared sorting module 1110 can collect and identify the identification information of graded objects passing through the shared sorting module 1110. In specific applications, the information obtained by the shared sorting module 1110 can be sent to the control system 1400, and the control system 1400 can control the shared sorting module 1110 to perform sorting according to the obtained information.

[0062] Fig. 3 is a schematic structural framework diagram of the first embodiment of the hierarchical sorting line module assembly provided by the present application. Please refer to Fig. 3. The hierarchical sorting line module assembly 1200 includes at least one sorting and palletizing sub-module assembly 1210, and the sorting and palletizing sub-module assembly 1210 includes a hierarchical sorting module 1211 and a hierarchical palletizing module 1212.

[0063] The hierarchical palletizing module 1212 is connected with the hierarchical sorting module 1211. The hierarchical sorting module 1211 is configured to sort out at least one grade of graded objects, and the hierarchical palletizing module 1212 can palletize the graded objects conveyed by the hierarchical sorting module 1211.

[0064] In the present embodiment, the hierarchical sorting line module assembly 1200 includes sorting and palletizing sub-module assemblies 1210, and the number of sorting and palletizing sub-module assemblies 1210 can be determined according to the number of grades of graded objects in the mixed incoming objects.

[0065] The sorting and palletizing sub-module assembly 1210 mainly includes a hierarchical sorting module 1211 and a hierarchical palletizing module 1212 connected to each other. The hierarchical sorting module 1211 is configured to sort graded objects, and the hierarchical palletizing module 1212 is configured to palletize graded objects and is located downstream of the hierarchical sorting module 1211, so as to receive the graded objects sorted by the upstream hierarchical sorting module 1211 and palletize the sorted graded objects.

[0066] The hierarchical sorting module 1211 generally includes an identification function unit, and the identification function unit in the hierarchical sorting module 1211 can collect the identification information of graded objects entering the hierarchical sorting module 1211. In specific applications, the information obtained by each module in the sorting and palletizing sub-module assembly 1210 can be sent to the control system 1400, and the control system 1400 can control each module in the sorting and palletizing sub-module assembly 1210 to cooperate according to the information to realize the sorting of corresponding graded objects.

[0067] Fig. 4 is a simplified schematic structural framework diagram of the second embodiment of the sorting device provided by the present application. Please refer to Fig. 4. In some optional embodiments, the sorting device 1000 further includes a pre-posed sorting line module assembly 1300, and the shared sorting line module assembly 1100 is connected with the pre-posed sorting line module assembly 1300.

[0068] The pre-posed sorting line module assembly 1300 is configured to sort out qualified graded objects to be conveyed to the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100.

[0069] In the present embodiment, the sorting device 1000 further includes a pre-posed sorting line module assembly 1300 arranged upstream of the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100. The pre-posed sorting line module assembly 1300 can sort out qualified graded objects, so that the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100 are only configured to sort qualified graded objects.

[0070] In specific applications, the pre-posed sorting line module assembly 1300 can obtain the identification information of graded objects entering therein and send the identification information to the control system 1400 to determine qualified graded objects.

[0071] It should be noted that in the case that the sorting device 1000 is applied to battery cell sorting, each battery cell generally corresponds to a cup placed on a conveying channel to assist in transportation and avoid damage caused by friction between battery cells. However, due to some reasons (for example, the battery cell on the cup is removed in advance due to failure in quality inspection), there is no battery cell on the cup, that is, an empty cup occurs. The pre-posed sorting line module assembly 1300 also needs to prevent empty cups from being conveyed to the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100. In other words, the pre-posed sorting line module assembly 1300 classifies empty cups and unqualified battery cells as one category and classifies qualified battery cells as another category, and conveys the two categories in different directions respectively.

[0072] Fig. 5 is a structural block diagram of the first embodiment of the pre-posed sorting line module assembly provided by the present application. Please refer to Fig. 5. In a further optional embodiment, the pre-posed sorting line module assembly 1300 includes a pre-posed sorting module 1310, and the pre-posed sorting module 1310 is configured to sort out qualified graded objects.

[0073] In the present embodiment, the pre-posed sorting module 1310 has the function of collecting identification information, and the control system 1400 can obtain the identification information collected by the pre-posed sorting module 1310 and control the pre-posed sorting module 1310 in the pre-posed sorting line module assembly 1300 to sort out qualified graded objects.

[0074] In specific applications, the pre-posed sorting module 1310 generally includes an identification function unit, and the identification function unit in the pre-posed sorting module 1310 can collect the identifiers of graded objects entering the pre-posed sorting module 1310. Of course, the control system 1400 can obtain and store the identification information collected by the pre-posed sorting module 1310 to count the quantities and proportions of various grades of graded objects entering the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100.

[0075] It should be noted that the above-mentioned shared sorting module 1110, hierarchical sorting module 1211 and pre-posed sorting module 1310 are all sorting devices, and all the three can adopt the same or different sorting devices. In specific applications, all the three can adopt rotary sorters, and the rotary sorter can adopt, for example, a Radio Frequency Identification (RFID) module, an NFC (Near Field Communication) module, an industrial camera, a code scanner, etc. as the identification function unit.

[0076] In some optional embodiments, the sorting module further includes a counting function unit. In specific applications, the rotary sorter can adopt a counter as the counting function unit, and the counter here can adopt, for example, a photoelectric counter, a vibration counter, etc. In other optional embodiments, the control system 1400 has a counting function unit, and the quantity of corresponding graded objects sorted out by the sorting module is counted by the control system 1400.

[0077] In an optional embodiment, the shared sorting line module assembly 1100 further includes a shared palletizing module 1130, and any grade of graded objects sorted out by the shared sorting module 1110 is conveyed to the shared palletizing module 1130 for palletizing.

[0078] In the present embodiment, the shared palletizing module 1130 is configured to palletize graded objects with the preset palletizing quantity. The shared sorting module 1110 is located upstream of the shared palletizing module 1130, and the sorted graded objects can be conveyed to the shared palletizing module 1130. In other words, the shared sorting line module assembly 1100 in the present embodiment is provided with the shared palletizing module 1130 to realize palletizing on graded objects with the preset palletizing quantity sorted out by the shared sorting module 1110.

[0079] In another optional embodiment, any grade of graded objects sorted out by the shared sorting module 1110 is conveyed to a hierarchical palletizing module 1212 in the hierarchical sorting line module assembly 1200 for palletizing.

[0080] In the present embodiment, the shared sorting line module assembly 1100 is not provided with the shared palletizing module 1130, and the shared sorting line module assembly 1100 shares one hierarchical palletizing module 1212 in the hierarchical sorting line module assembly 1200, so as to further reduce the use of palletizing modules, lower costs and reduce the space occupied by the device.

[0081] In an optional embodiment, any grade of graded objects sorted out by the shared sorting module 1110 can be conveyed to either the hierarchical palletizing module 1212 or the shared palletizing module 1130 for palletizing.

[0082] In other words, the shared sorting line module assembly 1100 in the present embodiment is not only provided with the shared palletizing module 1130, but also shares one hierarchical palletizing module 1212 with the hierarchical sorting line module assembly 1200. This situation is applicable when the shared sorting line module assembly 1100 contains more grades of graded objects.

[0083] In specific applications, the sorting modules and the palletizing modules are connected through object conveying channels. The sorting modules here include the shared sorting module 1110, the hierarchical sorting module 1211 and the pre-posed sorting module 1310, and the palletizing modules include the shared palletizing module 1130 and the hierarchical palletizing module 1212.

[0084] It should be noted that the palletizing module refers to a palletizing machine and generally includes a carrier conveying channel and a handling unit. The carrier conveying channel is configured to convey packaging containers for loading graded objects, and the handling unit is configured to handle the graded objects on the object conveying channel into the packaging containers on the packaging conveying line.

[0085] The handling unit here may include, for example, a robotic arm with multiple degrees of freedom, or a gripper device with multiple degrees of freedom, etc. The object conveying channel and the carrier conveying channel here may adopt conveying channels formed by, for example, conveying belts, conveying rollers, etc.

[0086] Please refer to Fig. 2. In an optional embodiment, the number of the shared sorting modules 1110 is 1, and the shared buffer module 1120 cooperates with the shared sorting module 1110 to form an object circulation loop.

[0087] In the present embodiment, the number of the shared sorting modules 1110 is 1, and the shared sorting modules 1110 is provided with one feed inlet and at least two discharge outlets. The shared buffer module 1120 can be connected with the feed inlet and one discharge outlet of the shared sorting module 1110 through an object conveying channel, and other discharge outlets of the shared sorting module 1110 are connected to corresponding palletizing modules through object conveying channels to allow sorted graded objects to pass through, so as to cooperate with the shared sorting module 1110 to form an object circulation loop. In this way, in the case that the quantity of graded objects does not reach the preset palletizing quantity, the graded objects circulate in the object circulation loop.

[0088] Fig. 6 is a structural block diagram of the second embodiment of the shared sorting line module assembly provided by the present application. Please refer to Fig. 6. In an optional embodiment, the number of the shared sorting modules 1110 is not less than 2, and a plurality of shared sorting modules 1110 are sequentially connected and cooperate with the shared buffer module 1120 to form an object circulation loop.

[0089] In the present embodiment, the number of the shared sorting modules 1110 is plural, and each shared sorting module 1110 is provided with one feed inlet and at least two discharge outlets. For two shared sorting modules 1110 adjacent in the upstream and downstream direction, one discharge outlet of an upstream shared sorting module 1110 is communicated with the feed inlet of a downstream shared sorting module 1110 through an object conveying channel, so as to realize the connection of the plurality of shared sorting modules 1110.

[0090] Both ends of the shared buffer module 1120 are respectively connected to the feed inlet of the most upstream shared sorting module 1110 and one discharge outlet of the most downstream shared sorting module 1110, thus forming an object circulation loop. Further, in the case that the quantity of graded objects does not reach the preset palletizing quantity, the graded objects circulate in the circulation loop.

[0091] Please refer to Fig. 3. In an optional embodiment, the number of the sorting and palletizing sub-module assemblies 1210 is not less than 2, and the hierarchical sorting modules 1211 in a plurality of sorting and palletizing sub-module assemblies 1210 are sequentially connected.

[0092] In the present embodiment, the number of the sorting and palletizing sub-module assemblies 1210 is plural, and the hierarchical sorting modules 1211 in the plurality of sorting and palletizing sub-module assemblies 1210 are sequentially connected to realize the sequential connection of the plurality of sorting and palletizing sub-module assemblies 1210. The hierarchical palletizing modules 1212 in the plurality of sorting and palletizing sub-module assemblies 1210 are independent of each other, so that each hierarchical palletizing module 1212 can only receive graded objects sorted out by the hierarchical sorting module 1211 connected with the hierarchical palletizing module 1212.

[0093] In specific applications, the hierarchical sorting module 1211 is provided with one feed inlet and at least two discharge outlets. For two hierarchical sorting modules 1211 adjacent in the upstream and downstream direction, one discharge outlet of an upstream hierarchical sorting module 1211 is connected to the feed inlet of a downstream hierarchical sorting module 1211, so as to realize the sequential connection of the plurality of hierarchical sorting modules 1211.

[0094] In a further optional embodiment, the shared sorting line module assembly 1100 is connected to the most downstream sorting and palletizing sub-module assembly 1210.

[0095] In the present embodiment, when the shared sorting line module assembly 1100 is provided with only one shared sorting module 1110, the feed inlet of the shared sorting module 1110 in the shared sorting line module assembly 1100 is connected to one discharge outlet of the hierarchical sorting module 1211 in the most downstream sorting and palletizing sub-module assembly 1210.

[0096] In the case that the shared sorting line module assembly 1100 is provided with a plurality of shared sorting modules 1110, the feed inlet of the most upstream shared sorting module 1110 in the shared sorting line module assembly 1100 is connected to one discharge outlet of the hierarchical sorting module 1211 in the most downstream sorting and palletizing sub-module assembly 1210.

[0097] In the case that the shared sorting line module assembly 1100 shares one hierarchical palletizing module 1212 in a plurality of hierarchical sorting line assemblies 1200, the shared sorting module 1110 in the shared sorting line module assembly 1100 is connected to the hierarchical palletizing module 1212 in the most downstream hierarchical sorting line module assembly 1200.

[0098] This arrangement allows the top N grades of graded objects with higher proportions to be sorted by the hierarchical sorting line module assembly 1200 first, and the latter M-N grades of graded objects with lower proportions to be sorted by the shared sorting line module assembly 1100 later, so as to be more conducive to the realization of sorting logic.

[0099] Please refer to Fig. 5. In some optional embodiments, the pre-posed sorting line module assembly 1300 further includes a pre-posed buffer module 1320, and the pre-posed buffer module 1320 is connected between the pre-posed sorting module 1310 and the hierarchical sorting line module assembly 1200. The pre-posed buffer module 1320 is configured to buffer qualified graded objects sorted out by the pre-posed sorting module 1310.

[0100] In the present embodiment, in addition to the pre-posed sorting module 1310, the pre-posed sorting line module assembly 1300 is additionally provided with the pre-posed buffer module 1320. The pre-posed buffer module 1320 is located downstream of the pre-posed sorting module 1310 and upstream of the hierarchical sorting line module assembly 1200, and the hierarchical sorting line module assembly 1200 is generally located upstream of the shared sorting line module assembly 1100.

[0101] The pre-posed buffer module 1320 has the function of buffering graded objects. Through the pre-posed buffer module 1320, part of qualified graded objects can be buffered, reducing the risk of congestion in the hierarchical sorting line module assembly 1200 and the shared sorting line module assembly 1100, and ensuring the accuracy of statistical samples and improving allocation efficiency.

[0102] It should be noted that the above-mentioned shared buffer module 1120 and pre-posed buffer module 1320 can be buffer towers, buffer channels, etc. for buffering graded objects, and can be selected according to design requirements.

[0103] Fig. 7 is a simplified partial schematic diagram of the third embodiment of the sorting device provided by the present application. Fig. 7 only shows the main components for realizing sorting. In the embodiment shown in Fig. 7, in the sorting device 1000, the number of the sorting and palletizing sub-module assemblies 1210 in the hierarchical sorting line module assembly 1200 is 4, the number of the shared sorting modules 1110 and the number of the shared buffer modules 1120 in the shared sorting line module assembly 1100 are each 1, and the shared sorting line module assembly 1100 is shared with the hierarchical palletizing module 1212 in the most downstream sorting and palletizing sub-module assembly 1210.

[0104] In addition, the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 in each sorting and palletizing sub-module assembly 1210 are connected through only one object conveying channel, and the maximum number of graded objects that can be sorted by the hierarchical sorting line module assembly 1200 is determined by the total number of object conveying channels between the hierarchical sorting module 1211 and the hierarchical palletizing module 1212. Moreover, the pre-posed sorting line module assembly 1300 in the sorting device 1000 is only provided with the pre-posed sorting module 1310.

[0105] In specific applications, the sorting device 1000 shown in Fig. 7 can be applied to sort mixed incoming objects with 12 grades of battery cells, i.e., M=12, where the hierarchical sorting line module assembly 1200 can sort out the top 4 grades of battery cells with the highest proportions, and the remaining 8 grades of battery cells are all sorted by the shared sorting line module assembly 1100. In addition, in the case that there is a remainder (less than the preset palletizing quantity) after sorting the top 4 grades of battery cells with the highest proportions, the battery cells with the remainder quantity can be conveyed to the shared sorting line module assembly 1100 to wait for sorting.

[0106] Fig. 8 is a simplified partial schematic diagram of the fourth embodiment of the sorting device provided by the present application. Fig. 8 only shows the main components for realizing sorting. In the embodiment shown in Fig. 8, in the sorting device 1000, the number of the sorting and palletizing sub-module assemblies 1210 in the hierarchical sorting line module assembly 1200 is 4, the number of the shared sorting modules 1110 in the shared sorting line module assembly 1100 is 2, the number of the shared buffer modules 1120 is 1, the upstream shared sorting module 1110 is connected to the hierarchical palletizing module 1212 in the most downstream sorting and palletizing sub-module assembly 1210, and the downstream shared sorting module 1110 is connected to the shared palletizing module 1130.

[0107] In addition, the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 in the upstream three sorting and palletizing sub-module assemblies 1210 are connected through two object conveying channels, the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 in the most downstream one sorting and palletizing sub-module assembly 1210 are connected through one object conveying channel, and the total number of object conveying channels between the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 is 7. Moreover, the pre-posed sorting line module assembly 1300 in the sorting device 1000 is only provided with the pre-posed sorting module 1310.

[0108] The sorting device 1000 shown in Fig. 8 can be applied to sort mixed incoming objects with 12 grades of battery cells, i.e., M=12, where the hierarchical sorting line module assembly 1200 can sort out the top 7 grades of battery cells with the highest proportions, and the remaining 5 grades of battery cells are all sorted by the shared sorting line module assembly 1100. In addition, in the case that there is a remainder (less than the preset palletizing quantity) after sorting the top 7 grades of battery cells with the highest proportions, the battery cells with the remainder quantity can be conveyed to the shared sorting line module assembly 1100 to wait for sorting.

[0109] In practice, the top 4 grades of battery cells with the highest proportions already account for 90% of the total quantity, so the hierarchical sorting line module assembly 1200 is still configured to sort the top 4 grades of graded objects with the highest proportions. Some object conveying channels in the hierarchical sorting line module assembly 1200 are classified into main channels and standby channels, and the main channels and standby channels are reasonably allocated according to the top 4 grades of graded objects with the highest proportions.

[0110] Fig. 9 is a simplified partial schematic diagram of the fifth embodiment of the sorting device provided by the present application. Fig. 9 only shows the main components for realizing sorting. In the embodiment shown in Fig. 9, in the sorting device 1000, the number of the sorting and palletizing sub-module assemblies 1210 in the hierarchical sorting line module assembly 1200 is 3, the number of the shared sorting modules 1110 in the shared sorting line module assembly 1100 is 2, the number of the shared buffer modules 1120 is 1, and both two shared sorting modules 1110 are connected to the shared palletizing module 1130.

[0111] In addition, the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 in the sorting and palletizing sub-module assembly 1210 are connected through two object conveying channels, and the total number of object conveying channels between the hierarchical sorting module 1211 and the hierarchical palletizing module 1212 is 6. Moreover, the pre-posed sorting line module assembly 1300 in the sorting device 1000 is provided with the pre-posed sorting module 1310 and the pre-posed buffer module 1320.

[0112] Fig. 9 shows that the sorting device 1000 can be applied to sort mixed incoming objects with 12 grades of battery cells, i.e., M=12, where the hierarchical sorting line module assembly 1200 is configured to dynamically sort battery cells with relative high proportions through six object conveying channels between the hierarchical sorting module 1211 and the hierarchical palletizing module 1212, and the remaining battery cells with lower proportions are sorted through the shared sorting line module assembly 1100.

[0113] The dynamic sorting here means that the higher the proportion, the more object conveying channels are occupied, i.e., the number of object conveying channels is allocated according to the proportion. In this case, there may be more grades of remaining battery cells with low proportions, so two shared sorting modules 1110 are configured to ensure sorting efficiency.

[0114] Of course, since the pre-posed buffer module 1320 can buffer mixed incoming objects, thereby ensuring the accuracy of statistical samples and avoids congestion.

[0115] It can be seen from the above that in the case that twelve grades of battery cells are needed to be sorted, only 4 palletizing modules may be used. Thus, the sorting device 1000 with the above modules can not only make full use of the production capacity of each palletizing module, but also reduce the use of palletizing modules, reduce the space occupied by the sorting device 1000, and lower the cost.

[0116] Fig. 10 is a simplified schematic diagram of the sixth embodiment of the sorting device provided by the present application. Fig. 11 is a simplified schematic diagram of the seventh embodiment of the sorting device provided by the present application. Fig. 12 is a simplified schematic diagram of the eighth embodiment of the sorting device provided by the present application. Fig. 13 is a simplified schematic diagram of the ninth embodiment of the sorting device provided by the present application.

[0117] It should be noted that Fig. 10 to Fig. 13 only show the relevant functional components of the sorting device 1000 for sorting and palletizing. The upstream and downstream relationships mentioned in this application are judged based on the conveying direction of graded objects. The "......" between the most upstream single-stage sorting line 2200 and the most downstream single-stage sorting line 2200 in Fig. 10 to Fig. 13 indicates that part of the single-stage sorting line 2200 is omitted.

[0118] Please refer to Fig. 10 to Fig. 13. The sorting device 1000 includes a shared sorting line 2100 and at least one single-stage sorting line 2200, and the shared sorting line 2100 is connected with one single-stage sorting line 2200.

[0119] The shared sorting line 2100 includes a shared buffer channel 2110 and at least one shared sorting station 2120. The shared buffer channel 2110 cooperates with the shared sorting station 2120 to form a circulation loop for buffering a plurality of grades of graded objects, and the shared sorting station 2120 can sort out any grade of graded objects from the circulation loop.

[0120] In the present embodiment, the sorting device 1000 can be used for sorting a variety of grades of battery cells. In other words, the graded objects here refer to graded battery cells, but are not limited thereto. For example, the objects can also refer to battery modules, solar cells, etc.

[0121] The single-stage sorting line 2200 is configured to sort out at least one grade of graded objects and perform palletizing, the shared sorting line 2100 forms a circulation loop, and the circulation loop is formed by the cooperation of the shared buffer channel 2110 and the shared sorting station 2120.

[0122] In specific applications, some graded objects that do not meet the sorting conditions can enter the circulation loop for circulation, so as to buffer part of the graded objects. When the graded objects in the circulation loop meet the sorting conditions, the shared sorting station 2120 sorts out the graded objects that meet the sorting conditions from the circulation loop for palletizing.

[0123] The palletizing here refers to loading graded objects that meet the preset palletizing quantity into a packaging container. The preset palletizing quantity is the capacity of the packaging container, i.e., the quantity for a single palletizing, and the packaging container can be a carton, etc. The sorting condition refers to whether the quantity of graded objects meets the quantity for a single palletizing.

[0124] It can be understood that quantities of various grades of graded objects entering the sorting device 1000 are different, and even the quantity of some graded objects cannot reach the quantity for a single palletizing. Therefore, the part of graded objects that cannot meet the quantity for a single palletizing can be conveyed to the shared sorting line 2100 for buffering, and this part of graded objects is mainly located in the shared buffer channel 2110 in the circulation loop.

[0125] As graded objects continue to enter the sorting device 1000, quantities of various grades of graded objects in the shared buffer channel 2110 will increase accordingly. Any grade of graded objects may reach the quantity for a single palletizing, and the shared sorting station 2120 can sort out the graded objects that reach the quantity for a single palletizing for the downstream palletizing process.

[0126] It can be seen that when sorting different grades of graded objects by the sorting device 1000 provided by the present application, part of the graded objects that do not meet the quantity for a single palletizing can be conveyed to the shared sorting line 2100 and circulate in the circulation loop. In the case that the quantity of any grade of graded objects in the circulation loop meets the quantity for a single palletizing, the graded objects can be sorted out by the shared sorting station 2120 for downstream palletizing.

[0127] In this way, part of the graded objects shares the shared sorting line 2100, thereby reducing the number of sorting lines, lower the device cost, and reduce the space occupied by the device. Moreover, the waiting phenomenon of palletizing stations due to not meeting the quantity for a single palletizing can be avoided, thereby making full use of the production capacity of the palletizing stations.

[0128] In an optional embodiment, the number of the single-stage sorting lines 2200 is 1, and the shared sorting line 2100 is connected with the single-stage sorting line 2200 and located downstream of the single-stage sorting line 2200.

[0129] In the present embodiment, the number of the single-stage sorting lines 2200 is only 1, which is suitable for the case where the number of grades of graded objects is relatively small.

[0130] In another optional embodiment, the number of the single-stage sorting lines 2200 is not less than 2, a plurality of single-stage sorting lines 2200 are sequentially connected, and the shared sorting line 2100 is connected with the most downstream single-stage sorting line 2200.

[0131] In the present embodiment, the number of the single-stage sorting lines 2200 is plural, and a plurality of single-stage sorting lines 2200 are sequentially connected to form a multi-stage sorting line, which is suitable for the case where the number of grades of graded objects is relatively large. It should be understood that the number of the single-stage sorting lines 2200 can be reasonably designed according to the number of grades of graded objects to be sorted.

[0132] In the above two optional embodiments, the shared sorting line 2100 is located at the most downstream, that is, graded objects first pass through the single-stage sorting line 2200 and then enter the shared sorting line 2100. In specific applications, the single-stage sorting line 2200 can be used for sorting graded objects with a large quantity, and the shared sorting line 2100 can buffer graded objects that do not meet the quantity for a single palletizing until the corresponding graded objects meet the quantity for a single palletizing and are sorted out.

[0133] It can be understood that in the case that the number of grades of graded objects is large, the number of grades of graded objects exceeding the quantity for a single palletizing will increase accordingly, and the number of the single-stage sorting lines 2200 should also be increased to ensure sufficient production capacity for sorting and palletizing.

[0134] In a further optional embodiment, the sorting device 1000 further includes a pre-posed sorting line 2300. In the case that the number of the single-stage sorting lines 2200 is 1, the pre-posed sorting line 2300 is connected with the single-stage sorting line 2200 and located upstream of the single-stage sorting line 2200.

[0135] In the case that the number of the single-stage sorting lines 2200 is not less than 2, the pre-posed sorting line 2300 is connected with the most upstream single-stage sorting line 2200.

[0136] In the present embodiment, the pre-posed sorting line 2300 is configured to sort out qualified graded objects, the pre-posed sorting line 2300 is located upstream of the single-stage sorting line 2200, and the shared sorting line 2100 is located at the most downstream, so that the graded objects entering the single-stage sorting line 2200 and the shared sorting line 2100 are all qualified graded objects.

[0137] It should be noted that arranging the shared sorting line 2100 at the most downstream facilitates the realization of the sorting logic of sorting graded objects with a large quantity first and then sorting graded objects with a small quantity. Of course, the shared sorting line 2100 is not limited to being arranged at the most downstream, and the shared sorting line 2100 can be connected to any single-stage sorting line 2200 or connected between two adjacent single-stage sorting lines 2200.

[0138] In the embodiment shown in Fig. 13, the shared sorting line 2100 is connected with the pre-posed sorting line 2300. Thus, in the case that the number of the single-stage sorting lines 2200 is 1, the shared sorting line 2100 and the single-stage sorting line 2200 are in a parallel relationship. In the case that the number of the single-stage sorting lines 2200 is not less than 2, the shared sorting line 2100 is in a parallel relationship with a multi-stage sorting line including a plurality of single-stage sorting lines 2200.

[0139] In the sorting device 1000 shown in Fig. 13, the pre-posed sorting line 2300 not only needs to determine qualified graded objects, but also distinguishes graded objects with a large quantity from graded objects with a small quantity, so as to convey different graded objects to different sorting lines.

[0140] It should be understood that it is difficult to ensure that the quantity of graded objects flowing to the single-stage sorting line 2200 is exactly an integer times the quantity for a single palletizing, and there is a remainder generally, where the remainder is less than the quantity for a single palletizing.

[0141] In the case that the shared sorting line 2100 is not located at the most downstream, there may be graded objects with a remainder quantity in the single-stage sorting line 2200 that are difficult to be palletized, causing the single-stage sorting line 2200 to be in a state of waiting for graded objects, which affects the palletizing efficiency.

[0142] In the case that the shared sorting line 2100 is located at the most downstream, the single-stage sorting line 2200 can first palletized the graded objects that meet the quantity for a single palletizing, and the graded objects with the remainder quantity finally flow into the shared sorting line 2100 and wait to be sorted out after meeting the quantity for a single palletizing. Obviously, arranging the shared sorting line 2100 at the most downstream can match better sorting logic and improve the palletizing efficiency.

[0143] In some optional embodiments, the single-stage sorting line 2200 includes a target sorting station 2210, a target palletizing station 2220, and a target palletizing channel 2230.

[0144] The target sorting station 2210 is connected with the target palletizing station 2220 through at least one target palletizing channel 2230. In the case that the number of the single-stage sorting lines 2200 is 1, both the pre-posed sorting line 2300 and the shared sorting line 2100 are connected with the target sorting station 2210.

[0145] In the case that the number of the single-stage sorting lines 2200 is 2, a plurality of target sorting stations 2210 are sequentially connected, the pre-posed sorting line 2300 is connected with the most upstream target sorting station 2210, and the shared sorting line 2100 is connected with the most downstream target sorting station 2210.

[0146] In the present embodiment, the single-stage sorting line 2200 mainly includes a target sorting station 2210, a target palletizing station 2220, and a target palletizing channel 2230.

[0147] In the case that the number of the single-stage sorting lines 2200 is 1, both the pre-posed sorting line 2300 and the shared sorting line 2100 are connected with the target sorting station 2210, and it is ensured that the pre-posed sorting line 2300 is located upstream of the target sorting station 2210 and the shared sorting line 2100 is located downstream of the target sorting station 2210.

[0148] In the case that the number of the single-stage sorting lines 2200 is plural, the target sorting stations 2210 in each single-stage sorting line 2200 are sequentially connected to realize the sequential connection of the single-stage sorting lines 2200, thereby forming a multi-stage sorting line. The pre-posed sorting line 2300 and the shared sorting line 2100 are respectively connected to the most upstream target sorting station 2210 and the most downstream target sorting station 2210 in the multi-stage sorting line.

[0149] Fig. 14 is a simplified schematic diagram of the shared sorting line 2100 in Fig. 10. Fig. 15 is a simplified schematic diagram of the shared sorting line 2100 in Fig. 11. Fig. 16 is a simplified schematic diagram of the shared sorting line 2100 in Fig. 12. In some optional embodiments, the shared sorting station 2120 includes a shared feed inlet 2121, a shared circulation discharge outlet 2122, and at least one shared sorting discharge outlet 2123.

[0150] Please refer to Fig. 14. In an optional embodiment, the number of the shared sorting stations 2120 is 1, and both ends of the shared buffer channel 2110 are connected with the shared sorting station 2120 to form a circulation loop.

[0151] In specific applications, both ends of the shared buffer channel 2110 are respectively connected with the shared feed inlet 2121 and the shared circulation discharge outlet 2122, so as to form a circulation loop in cooperation with the shared sorting station 2120.

[0152] It should be noted that the shared feed inlet 2121 can introduce graded objects flowing in from the shared buffer channel 2110 and graded objects flowing in from the upstream single-stage sorting line 2200. The graded objects flowing in from the upstream single-stage sorting line 2200 are new graded objects. In the case that the quantity of graded objects does not meet the quantity for a single palletizing, the graded objects can flow out from the shared circulation discharge outlet 2122 to enter the shared buffer channel 2110, thereby realizing circulation in the circulation loop.

[0153] Please refer to Fig. 15. In another optional embodiment, the number of the shared sorting stations 2120 is not less than 2, a plurality of shared sorting stations 2120 are sequentially connected, and both ends of the shared buffer channel 2110 are respectively connected with the most upstream shared sorting station 2120 and the most downstream shared sorting station 2120 to form a circulation loop.

[0154] In specific applications, both ends of the shared buffer channel 2110 are respectively connected with the shared feed inlet 2121 of the most upstream shared sorting station 2120 and the shared circulation discharge outlet 2122 of the most downstream shared sorting station 2120, so as to form a circulation loop in cooperation with a plurality of shared sorting stations 2120.

[0155] Of course, the shared feed inlet 2121 of the most upstream shared sorting station 2120 can introduce graded objects flowing in from the shared buffer channel 2110 and graded objects flowing in from the upstream single-stage sorting line 2200. In that case that the quantity of graded objects does not meet the quantity for a single palletizing, the graded objects can pass through a plurality of shared sorting stations 2120 in sequence and flow out from the shared circulation discharge outlet 2122 of the most downstream shared sorting station 2120 to enter the shared buffer channel 2110.

[0156] Please refer to Fig. 11 and Fig. 15. In an optional embodiment, the shared sorting line 2100 further includes a shared palletizing channel 2130 and at least one shared palletizing station 2140, and the shared sorting station 2120 is connected with the shared palletizing station 2140 through the shared palletizing channel 2130.

[0157] In the present embodiment, the shared sorting line 2100 is provided with a shared palletizing station 2140, and the shared palletizing station 2140 can receive graded objects sorted out from the shared sorting station 2120 and perform palletizing. Graded objects are conveyed between the shared palletizing station 2140 and the shared sorting station 2120 through the shared palletizing channel 2130. Specifically, the shared sorting discharge outlet 2123 in the shared sorting station 2120 is connected with the shared palletizing station 2140 through the shared palletizing channel 2130.

[0158] Please refer to Fig. 10 and Fig. 14. In another optional embodiment, the shared sorting station 2120 is connected with the target palletizing station 2220 in the single-stage sorting line 2200 through the shared palletizing channel 2130.

[0159] In the present embodiment, the shared sorting line 2100 is not provided with the shared palletizing station 2140, and the shared sorting line 2100 shares one target palletizing station 2220 in the single-stage sorting line 2200. In specific applications, the shared sorting line 2100 shares the target palletizing station 2220 in the most downstream single-stage sorting line 2200. Specifically, the shared sorting discharge outlet 2123 in the shared sorting station 2120 is connected with the target palletizing station 2220 in the most downstream single-stage sorting line 2200 through the shared palletizing channel 2130.

[0160] In comparison, the case where the shared sorting line 2100 is provided with the shared palletizing station 2140 is more suitable for the situation where there are many grades of graded objects, and can be adapted to the application of a plurality of shared sorting stations 2120 to improve sorting efficiency.

[0161] The case where the shared sorting line 2100 is not provided with the shared palletizing station 2140 is more suitable for the situation where there are not many grades of graded objects, which can reduce the application of palletizing stations and further reduce costs and the space occupied by the device.

[0162] Please refer to Fig. 12 and Fig. 16. In yet another optional embodiment, the shared sorting station 2120 is connected with the shared palletizing station 2140 through the shared palletizing channel 2130, and the shared sorting station 2120 is connected with the target palletizing station 2220 in the single-stage sorting line 2200 through the shared palletizing channel 2130.

[0163] In the present embodiment, the shared sorting line 2100 is provided with the shared palletizing station 2140 and also shares one target palletizing station 2220 in the single-stage sorting line 2200. In specific applications, the shared target palletizing station 2220 is the target palletizing station 2220 in the most downstream single-stage sorting line 2200.

[0164] In the illustrated embodiment, the number of shared sorting discharge outlets 2123 in the shared sorting station 2120 is 2, and the shared sorting discharge outlets 2123 are respectively connected with the shared palletizing station 2140 and the target palletizing station 2220 in the most downstream single-stage sorting line 2200 through one shared palletizing channel 2130.

[0165] It can be known from the above that the shared sorting discharge outlet 2123 in the shared sorting station 2120 is connected with the palletizing station through the shared palletizing channel 2130, where the palletizing station here includes the shared palletizing station 2140 and the target palletizing station 2220.

[0166] It should be noted that in an application scenario, the multi-stage sorting line formed by the single-stage sorting line 2200 can sort out the top several grades of graded objects with the largest quantities among multiple grades of graded objects, and the most downstream single-stage sorting line 2200 correspondingly sorts out one grade of graded objects with the smallest quantity among the top several grades of graded objects with the largest quantities. Therefore, the probability that the most downstream target palletizing station 2220 is in an idle state is relatively high, so that the production capacity of the palletizing station can be fully utilized to improve efficiency.

[0167] Fig. 17 is a simplified schematic diagram of the single-stage sorting line 2200 in Fig. 10. Please refer to Fig. 17 and combine with Fig. 10 to Fig. 12.

[0168] In an optional embodiment, in the case that the number of the single-stage sorting lines 2200 is 1, the pre-posed sorting line 2300 is connected with the target feed inlet 2211, the shared sorting line 2100 is connected with the target sorting discharge outlet 2212, and the target palletizing discharge outlet 2213 is connected with the target palletizing station 2220 through the target palletizing channel 2230.

[0169] In the present embodiment, the pre-posed sorting line 2300 and the shared sorting line 2100 are respectively connected with the target feed inlet 2211 and the target palletizing discharge outlet 2213 of the single-stage sorting line 2200, so as to be respectively located upstream and downstream of the single-stage sorting line 2200. In addition, the target palletizing discharge outlet 2213 is connected with the target palletizing station 2220 through the target palletizing channel 2230.

[0170] In another optional embodiment, in the case that the number of the single-stage sorting lines 2200 is not less than 2, the pre-posed sorting line 2300 is connected with the target feed inlet 2211 of the most upstream target sorting station 2210, and the shared sorting line 2100 is connected with the target sorting discharge outlet 2212 of the most downstream target sorting station 2210.

[0171] For two adjacent single-stage sorting lines 2200, the target sorting discharge outlet 2212 of the upstream target sorting station 2210 is connected to the target feed inlet 2211 of the downstream target sorting station 2210.

[0172] The target palletizing discharge outlet 2213 of each target sorting station 2210 is connected to the corresponding target palletizing station 2220 through the corresponding target palletizing channel 2230.

[0173] In the present embodiment, the adjacent relationship here refers to being adjacent in the upstream and downstream direction. In the case that the number of the single-stage sorting lines 2200 is plural, the target sorting discharge outlet 2212 in the upstream one of the two adjacent single-stage sorting lines 2200 is connected to the target feed inlet 2211 in the downstream one of the single-stage sorting lines 2200, so as to realize the sequential connection of the multiple single-stage sorting lines 2200 to form a multi-stage sorting line.

[0174] In addition, the pre-posed sorting line 2300 and the shared sorting line 2100 are respectively connected to the target feed inlet 2211 of the most upstream target sorting station 2210 and the target sorting discharge outlet 2212 of the most downstream target sorting station 2210, so as to arrange the pre-posed sorting line 2300 and the shared sorting line 2100 upstream and downstream of the multi-stage sorting line.

[0175] In addition, the target palletizing discharge outlet 2213 of each target sorting station 2210 corresponds to a target palletizing channel 2230 so as to be connected with the target palletizing station 2220. Of course, part of the target palletizing discharge outlets 2213 in the target sorting station 2210 that are not matched with the target palletizing channels 2230 can be used as standby palletizing discharge outlets.

[0176] In an optional embodiment, the pre-posed sorting line 2300 includes a pre-posed sorting station 2310, and the pre-posed sorting station 2310 is connected to the single-stage sorting line 2200.

[0177] In the present embodiment, the pre-posed sorting line 2300 only includes the pre-posed sorting station 2310, and qualified graded objects are sorted out through the pre-posed sorting station 2310 and flow into the corresponding single-stage sorting line 2200.

[0178] In a further optional embodiment, the pre-posed sorting line 2300 further includes a pre-posed buffer channel 2320, and the pre-posed buffer channel 2320 is connected between the pre-posed sorting station 2310 and the single-stage sorting line 2200.

[0179] In the present embodiment, the pre-posed sorting line 2300 is additionally provided with the pre-posed buffer channel 2320, and the pre-posed buffer channel 2320 is configured to buffer graded objects. The pre-posed buffer channel 2320 is located downstream of the pre-posed sorting station 2310 and upstream of the single-stage sorting line 2200. It can be seen that the pre-posed buffer channel 2320 buffers qualified graded objects to be flowed into the single-stage sorting line 2200. Through the pre-posed buffer channel 2320, congestion can be avoided, which is beneficial to improving sorting accuracy.

[0180] In a further optional embodiment, the pre-posed buffer channel 2320 is configured to be able to accommodate graded objects that are integer times the preset palletizing quantity. In other words, the pre-posed buffer channel 2320 can accommodate graded objects that are integer times the quantity for a single palletizing.

[0181] Preferably, the quantity of graded objects that the pre-posed buffer channel 2320 can accommodate is not less than a multiple of half the total number of grades of graded objects times the preset palletizing quantity. For example, the total number of grades of graded objects is 12, and the pre-posed buffer channel 2320 can accommodate graded objects with a quantity not less than 6 times the preset palletizing quantity.

[0182] In a further optional embodiment, the shared buffer channel 2110 is configured to be able to accommodate graded objects that are integer times the preset palletizing quantity.

[0183] Preferably, the shared buffer channel 2110 is configured to be able to accommodate graded objects with a quantity not less than a multiple of the number of palletizing channels times the preset palletizing quantity. In other words, the capacity of the shared buffer channel 2110 is determined by the number of palletizing channels, where the palletizing channels include the target palletizing channel 2230 and the shared palletizing channel 2130. For example, in the case that the number of the target palletizing channels 2230 and the shared palletizing channels 2130 is 8, the capacity of the shared buffer channel 2110 is not less than 8 times the preset palletizing quantity.

[0184] It should be noted that the palletizing channel is an object conveying channel, which can adopt, for example, a belt conveying channel, a roller conveying channel, etc. In specific applications, the capacity of the palletizing channel is not less than 1 time the preset palletizing quantity.

[0185] In specific applications, various grades of graded objects are pre-configured with identifiers, and different graded objects are provided with different identifiers. By obtaining the identification information, the quantity of various objects can be counted, and then the proportion of various objects in the incoming objects can be determined. The identifiers here include, for example, bar codes, two-dimensional codes, electronic tags, inductive elements, etc. Of course, in the case that the pre-posed buffer channel 2320 is not provided, the identification information of various grades of graded objects passing through the pre-posed sorting station 2310 is directly obtained through the pre-posed sorting station 2310, and then the quantities and proportions of various grades of graded objects are determined. In the case that the pre-posed buffer channel 2320 is provided, the quantity of various grades of graded objects in the pre-posed buffer channel 2320 can also be determined through the pre-posed sorting station 2310.

[0187] The identification device here can adopt, for example, an RFID (Radio Frequency Identification) identification module, an NFC (Near Field Communication) module, an industrial camera, a code scanner, etc. The counting device can adopt, for example, a photoelectric counter, a vibration counter, etc.

[0188] In specific applications, the sorting station can adopt a rotary sorter, which is provided with an RFID identification module and can identify bar codes on graded objects, and the rotary sorter is also provided with a photoelectric counter to count the quantity of graded objects flowing into the corresponding palletizing station.

[0189] It can be known from the above that the palletizing stations include the shared palletizing station 2140 and the target palletizing station 2220, and the palletizing stations are configured to palletize graded objects. The palletizing station includes a handling device and a carrier channel, where the carrier channel is configured to convey packaging containers for palletizing of graded objects, and the handling device is configured to handle the graded objects on the palletizing channel into the packaging containers.

[0190] In specific applications, the carrier channel can adopt a roller conveying channel, and the handling device can adopt, for example, a multi-degree-of-freedom robotic arm, a gripper device with multiple degrees of freedom, etc.

[0191] It can be known from the above that the buffer channels include the shared buffer channel 2110 and the pre-posed buffer channel 2320. In specific applications, the buffer channel can adopt, for example, a buffer tower, an object conveying channel with a certain capacity, etc.
