Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics, in particular to a cargo sorting method and system, an electronic device and a readable storage medium. BACKGROUND

[0002] With the development of Internet technology, more and more e-commerce platforms have emerged. With the increase of e-commerce platforms, the logistics industry has also developed rapidly. For the airside site of a large logistics hub, an "island" is often used as the most basic regional unit, including a cargo packing and loading island, a cargo unpacking and unloading island, and a loading and unloading integrated island (both packing and unpacking functions). The airside site of a large logistics hub often has multiple such islands. How to improve the sorting capacity within the islands and between the islands is a challenge to process design.

[0003] At present, the sorting system design of a large logistics hub site is generally complex. The cargo generally goes through unloading, pre-sorting, final sorting, and loading. Usually, the cargo is unloaded in each island, then transported to the pre-sorting machine, pre-sorted by the pre-sorting machine, and then transported to the final sorting machine in the corresponding island for loading. Since the cargo unloaded in each island is transported to the pre-sorting machine for sorting, it often leads to congestion of the pre-sorting machine, and increases the complexity of the sorting process and the sorting time.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0059] As described in the background, the sorting system design of large logistics hub sites is generally complex, and the goods usually go through unloading, pre-sorting, final sorting, loading, etc. Usually, the goods are unloaded in each island, then transported to the pre-sorting machine, pre-sorted by the pre-sorting machine, and then transported to the final sorting machine in the corresponding island for loading. Since the goods unloaded in each island are transported to the pre-sorting machine for sorting, it often leads to congestion of the pre-sorting machine, and increases the complexity of the sorting process and the sorting time.

[0060] Based on the above research, the embodiments of the present application provide a goods sorting method, system, electronic device and readable storage medium. The destination information of the goods to be sorted is obtained, and a first loading and unloading area for loading and unloading the goods to be sorted is determined. It is detected whether the destination information of the goods to be sorted belongs to the first loading and unloading area. If it belongs to the first loading and unloading area, the goods to be sorted are controlled to be transported to the final sorting equipment of the first loading and unloading area. If it does not belong to the first loading and unloading area, the goods to be sorted are controlled to be transported to the pre-sorting equipment. The goods to be sorted are sorted by the pre-sorting equipment. In this way, by determining the destination information of the goods to be sorted, the goods to be sorted belonging to the first loading and unloading area are directly transported to the final sorting equipment of the first loading and unloading area without pre-sorting by the pre-sorting equipment, effectively reducing the probability of congestion of the pre-sorting machine, simplifying the sorting process and improving the sorting efficiency.

[0061] Please refer to Figure 1 , Figure 1 A structural schematic diagram of the goods sorting system provided by the present embodiment, the goods sorting system provided by the present embodiment can be used in airports, stations and other logistics hubs. The goods sorting system provided by the present embodiment comprises a control device 10, a pre-sorting equipment 40 and at least one final sorting equipment 30 and a loading and unloading equipment 20.

[0062] Since the destinations of the goods sorted in the logistics hub site are usually different, i.e. transported to different places, in order to sort and load and unload the goods with different destinations, the logistics hub site usually sets up multiple loading and unloading areas (i.e. loading and unloading islands), each of which corresponds to a destination. In order to facilitate the transportation of goods with different destinations to the corresponding loading and unloading area, the goods sorting system provided by the present embodiment sets up at least one final sorting equipment 30 and loading and unloading equipment 20 in each loading and unloading area, i.e. each loading and unloading area sets up a final sorting equipment 30 and loading and unloading equipment 20, and the loading and unloading equipment 20 of each loading and unloading area is provided with a pre-sorting transportation line 50 between the pre-sorting equipment 40 and the loading and unloading equipment 20, so as to transport the goods between the pre-sorting equipment 40 and the loading and unloading equipment 20 through the pre-sorting transportation line 50.

[0063] Each loading and unloading area is provided with a loading and unloading device 20 at the unloading end and the loading end. The loading and unloading device 20 at the unloading end is used for unloading the goods to be sorted, and the loading and unloading device 20 at the loading end is used for packing and loading the goods. The loading and unloading device 20 can be composed of a swing wheel and a mechanical arm, wherein the swing wheel is used for controlling the transportation direction of the unloaded goods, and the mechanical arm is used for unloading or packing the goods.

[0064] Optionally, the goods to be sorted can be unloaded by the loading and unloading device 20 at the unloading end of the loading and unloading area and swung to the pre-sorting transportation line 50, transported to the pre-sorting sorting device 40 through the pre-sorting transportation line 50, sorted by the pre-sorting sorting device 40 according to the destination information of the goods to be sorted, and transported to the corresponding loading and unloading area through the sorting transportation line 60, finally sorted by the final sorting device 30 of the loading and unloading area, and then packed and loaded by the loading and unloading device 20 at the loading end to be transported to the next link. Since the goods unloaded by each loading and unloading area are transported to the pre-sorting sorting device 40 for pre-sorting, the pre-sorting sorting device 40 is congested, the sorting process is complex, and the sorting time is increased. In order to reduce the sorting time, improve the processing capacity of the goods sorting system, and simplify the sorting process of the system, a first transportation line 70 is arranged between the final sorting device 30 and the loading and unloading device 20 in each loading and unloading area in the embodiment, and the goods are transported between the final sorting device 30 and the loading and unloading device 20 through the first transportation line 70.

[0065] When the destination of the unloaded goods is the loading and unloading area where the goods are unloaded, the goods can be directly transported to the final sorting device 30 of the loading and unloading area through the first transportation line 70 for sorting, and then packed and loaded by the loading and unloading device 20 at the loading end of the loading and unloading area to be directly transported to the next link. If the destination of the unloaded goods is not the loading and unloading area, the goods can be transported to the pre-sorting sorting device 40 through the pre-sorting transportation line 50, sorted by the pre-sorting sorting device 40 according to the destination information of the unloaded goods, and transported to the corresponding loading and unloading area through the sorting transportation line 60, finally sorted and packed by the final sorting device 30 of the corresponding loading and unloading area to be transported to the next link.

[0066] Based on this, in the embodiment, the control device 10 is used to acquire the destination information of the goods to be sorted, determine a first loading and unloading area for unloading the goods to be sorted, and detect whether the destination information of the goods to be sorted belongs to the first loading and unloading area. The loading and unloading device 20 is used to transport the goods to be sorted to the final sorting device 30 of the first loading and unloading area through the first transportation line 70 or to the pre-sorting sorting device 40 through the pre-sorting transportation line 50 according to the destination information of the goods to be sorted, and sort the goods to be sorted by the pre-sorting sorting device 40.

[0067] The goods to be sorted can be single goods or batch goods (i.e., including multiple goods). If the batch goods, the destination of each goods in the batch goods can be the same or different.

[0068] In the embodiment, the goods to be sorted are provided with an identification code, and the destination information of the goods to be sorted is recorded in the identification code. The embodiment can be provided with a scanning device, which can be electrically connected or communicatively connected with the control device 10. The scanning device can scan the identification code on the goods to be sorted to obtain the destination information of the goods to be sorted. After obtaining the destination information of the goods to be sorted, the scanning device can transmit the destination information of the goods to be sorted to the control device 10, and the control device 10 can obtain the destination information of the goods to be sorted. The destination information of the goods to be sorted represents the final sorting destination of the goods to be sorted, i.e., the final sorting destination.

[0069] In order to improve the sorting efficiency, in the embodiment, the proportion of goods flowing to each destination can be determined according to the destination information of the goods to be sorted, and then the first loading and unloading area can be determined according to the destination corresponding to the maximum proportion of goods.

[0070] For example, in the goods to be sorted, 50% of the goods go to the A destination, 20% of the goods go to the B destination, 10% of the goods go to the C destination, 10% of the goods go to the D destination, 5% of the goods go to the E destination, and 5% of the goods go to the F destination. Among them, the proportion of goods to the A destination is the largest, and the loading and unloading area corresponding to the A destination is set as the first loading and unloading area. The batch of goods to be sorted is transported to the loading and unloading area corresponding to the A destination, and unloaded by the loading and unloading device 20 of the unloading end of the loading and unloading area.

[0071] After the first loading and unloading area for unloading the goods to be sorted is determined, the goods to be sorted can be transported to the first loading and unloading area, and the goods to be sorted can be unloaded by the loading and unloading device 20 at the unloading end of the first loading and unloading area.

[0072] After the goods to be sorted are unloaded, for each goods to be sorted, the destination information of the goods to be sorted is obtained, and then it is detected whether the destination information of the goods to be sorted belongs to the first loading and unloading area, i.e., whether the destination of the goods to be sorted is the first loading and unloading area. If the destination information of the goods to be sorted belongs to the first loading and unloading area, it indicates that the goods to be sorted are finally sorted in the first loading and unloading area. If the destination information of the goods to be sorted does not belong to the first loading and unloading area, it indicates that the goods to be sorted are not finally sorted in the first loading and unloading area.

[0073] In the embodiment, if the destination information of the to-be-sorted goods indicates that the to-be-sorted goods are to be finally sorted in the first loading and unloading area, the loading and unloading device 20 directly transports the to-be-sorted goods to the final sorting device 30 of the first loading and unloading area through the first transport line 70; if the destination information of the to-be-sorted goods indicates that the to-be-sorted goods are not to be finally sorted in the first loading and unloading area, the loading and unloading device 20 transports the to-be-sorted goods to the pre-sorting device 40 through the pre-sorting transport line 50.

[0074] Optionally, when the to-be-sorted goods are to be finally sorted in the first loading and unloading area, the control device 10 can issue a first control instruction to the loading and unloading device 20 of the first loading and unloading area, and the loading and unloading device 20, after receiving the first control instruction, responds to the first control instruction to swing the to-be-sorted goods to the first transport line 70, i.e., to sort the to-be-sorted goods to the first transport line 70, directly transports the to-be-sorted goods to the final sorting device 30 of the first loading and unloading area through the first transport line 70, and directly sorts the to-be-sorted goods by the final sorting device 30 of the first loading and unloading area.

[0075] When the to-be-sorted goods are not to be finally sorted in the first loading and unloading area, the control device 10 can issue a second control instruction to the loading and unloading device 20 of the first loading and unloading area, and the loading and unloading device 20, after receiving the second control instruction, responds to the second control instruction to swing the to-be-sorted goods to the pre-sorting transport line 50, transports the to-be-sorted goods to the pre-sorting device 40 through the pre-sorting transport line 50, and sorts the to-be-sorted goods by the pre-sorting device 40.

[0076] When the pre-sorting device 40 sorts the to-be-sorted goods, the to-be-sorted goods are sorted to the sorting transport line 60 of the corresponding loading and unloading area according to the destination of the to-be-sorted goods, and then the to-be-sorted goods are transported to the corresponding loading and unloading area for final sorting by the final sorting device 30 of the corresponding loading and unloading area. For example, if the destination of the to-be-sorted goods is C, the pre-sorting device sorts the to-be-sorted goods to the sorting transport line of the loading and unloading area corresponding to the C destination, thereby transporting the to-be-sorted goods to the loading and unloading area corresponding to the C destination for final sorting by the final sorting device of the loading and unloading area corresponding to the C destination.

[0077] The goods sorting system provided by the embodiment is characterized in that a first conveying line is arranged between the final sorting device and the loading and unloading device in each loading and unloading area; after the destination information of the goods to be sorted is obtained and the first loading and unloading area where the goods to be sorted are unloaded is determined, it is detected whether the destination information of the goods to be sorted belongs to the first loading and unloading area; if the destination information belongs to the first loading and unloading area, the goods to be sorted are directly conveyed to the final sorting device in the first loading and unloading area through the loading and unloading device in the first loading and unloading area; if the destination information does not belong to the first loading and unloading area, the goods to be sorted are conveyed to the pre-sorting device through the loading and unloading device in the first loading and unloading area, and the pre-sorting device sorts the goods to be sorted. In this way, by determining the destination information of the goods to be sorted, the goods to be sorted belonging to the first loading and unloading area are directly conveyed to the final sorting device in the first loading and unloading area without pre-sorting through the pre-sorting device, thereby effectively reducing the probability of pre-sorting machine congestion, simplifying the sorting process and improving the sorting efficiency.

[0078] In optional embodiments, a conveying line can also be arranged between the loading and unloading device in each loading and unloading area and the final sorting device in other loading and unloading areas. In this way, when the goods are unloaded in any loading and unloading area, each goods to be sorted can be directly conveyed to the loading and unloading area corresponding to the destination of the sorting goods without secondary sorting through the pre-sorting device. However, in actual applications, a plurality of loading and unloading areas are arranged in a logistics hub site. If a conveying line is arranged between the loading and unloading device in each loading and unloading area and the final sorting device in other loading and unloading areas, the conveying line arrangement will be complex and the cost will be increased.

[0079] In order to further improve the efficiency of goods sorting, simplify the sorting process and reduce the sorting cost, as shown in FIG. Figure 2 In the embodiment, a second conveying line 80 is arranged between the loading and unloading device 20 in each loading and unloading area and the final sorting device 30 in the loading and unloading area closest to the loading and unloading device 20. Based on this, the control device 10 of the embodiment can also be used to determine the second loading and unloading area closest to the first loading and unloading area and detect whether the destination information of the goods to be sorted belongs to the second loading and unloading area.

[0080] The loading and unloading device 20 is used to convey the goods to be sorted to the final sorting device 30 in the second loading and unloading area through the second conveying line 80 or convey the goods to be sorted to the pre-sorting device 40 through the pre-sorting line 50 according to the destination information of the goods to be sorted.

[0081] In the embodiment, the control device 10 can pre-obtain the position information of each loading and unloading area, determine the target loading and unloading area closest to each loading and unloading area according to the position information of the loading and unloading area and the position information of other loading and unloading areas, and then establish the position relationship between each loading and unloading area and the target loading and unloading area closest to the loading and unloading area to obtain the position relationship data.

[0082] For example, there are loading and unloading areas A, B, C, D, E and F, wherein the loading and unloading area A is closest to the loading and unloading area B, the loading and unloading area B is closest to the loading and unloading area A, the loading and unloading area C is closest to the loading and unloading area D, the loading and unloading area D is closest to the loading and unloading area E, the loading and unloading area E is closest to the loading and unloading area F, and the loading and unloading area F is closest to the loading and unloading area E. Then, the second transport line is arranged between the loading and unloading area A and the loading and unloading area B to establish the positional relationship between the loading and unloading area A and the loading and unloading area B; the second transport line is arranged between the loading and unloading area C and the loading and unloading area D to establish the positional relationship between the loading and unloading area C and the loading and unloading area D; the second transport line is arranged between the loading and unloading area D and the loading and unloading area E to establish the positional relationship between the loading and unloading area D and the loading and unloading area E; and the second transport line is arranged between the loading and unloading area E and the loading and unloading area F to establish the positional relationship between the loading and unloading area E and the loading and unloading area F.

[0083] After obtaining the positional relationship of each loading and unloading area, the positional relationship data can be obtained according to the positional relationship of each loading and unloading area. After obtaining the positional relationship data, the second loading and unloading area closest to the first loading and unloading area can be obtained according to the positional relationship data.

[0084] After determining the second loading and unloading area closest to the first loading and unloading area, for the to-be-picked goods, if the destination of the to-be-picked goods does not belong to the first loading and unloading area, it is detected whether the destination information of the to-be-picked goods belongs to the second loading and unloading area. If the destination information belongs to the second loading and unloading area, it is indicated that the to-be-picked goods is finally picked in the second loading and unloading area. If the destination information of the to-be-picked goods does not belong to the second loading and unloading area, it is indicated that the to-be-picked goods is not finally picked in the second loading and unloading area.

[0085] In this embodiment, if the destination information of the to-be-picked goods indicates that the to-be-picked goods is finally picked in the second loading and unloading area, the loading and unloading device 20 directly transports the to-be-picked goods to the final picking device 30 of the second loading and unloading area through the second transport line 80. If the destination information of the to-be-picked goods indicates that the to-be-picked goods is not finally picked in the second loading and unloading area, the loading and unloading device 20 transports the to-be-picked goods to the pre-picking device 40 through the pre-picking transport line 50.

[0086] Optionally, when the to-be-sorted goods are subjected to final sorting at the second loading and unloading area, the control device 10 can issue a third control instruction to the loading and unloading device 20 of the first loading and unloading area, and the loading and unloading device 20, after receiving the third control instruction, responds to the third control instruction to swing the to-be-sorted goods to the second transport line 80, i.e., to sort the to-be-sorted goods to the second transport line 80, and directly transport the to-be-sorted goods to the final sorting device 30 of the second loading and unloading area through the second transport line 80 for sorting by the final sorting device 30 of the second loading and unloading area.

[0087] When the to-be-sorted goods are not subjected to final sorting at the first loading and unloading area and are not subjected to final sorting at the second loading and unloading area, the control device 10 can issue a second control instruction to the loading and unloading device 20 of the first loading and unloading area, and the loading and unloading device 20, after receiving the second control instruction, responds to the second control instruction to swing the to-be-sorted goods to the pre-sorting transport line 50, and transport the to-be-sorted goods to the pre-sorting sorting device 40 through the pre-sorting transport line 50 for sorting by the pre-sorting sorting device 40.

[0088] The goods sorting system provided in the embodiment sets the first transport line between the final sorting device and the loading and unloading device of each loading and unloading area, and sets the second transport line between the loading and unloading device of each loading and unloading area and the final sorting device of the nearest loading and unloading area, so that, for the to-be-sorted goods belonging to the local loading and unloading area and the nearest adjacent loading and unloading area, the to-be-sorted goods can be directly transported to the final sorting device of the nearest adjacent loading and unloading area without being transported to the pre-sorting sorting device for pre-sorting, thereby improving the sorting efficiency, simplifying the sorting process, and reducing the probability of pre-sorting sorting device blockage.

[0089] Since the second transport line 80 is set between the loading and unloading device 20 of each loading and unloading area and the final sorting device 30 of the nearest loading and unloading area, and the pre-sorting transport line 50 is set between the loading and unloading device 20 of each loading and unloading area and the pre-sorting sorting device 40, each loading and unloading area will receive the to-be-sorted goods transported from the nearest loading and unloading area and the to-be-sorted goods transported from the pre-sorting sorting device.

[0090] In order to facilitate sorting of the to-be-sorted goods transported from the nearest loading and unloading area and the to-be-sorted goods transported from the pre-sorting sorting device, in the embodiment, the first transport line of each loading and unloading area is provided with a first merging point and a second merging point, the first transport line 70 of each loading and unloading area is connected to the second transport line 80 of the loading and unloading area taking the loading and unloading area as the second loading and unloading area through the first merging point, and is connected to the sorting transport line 60 of the pre-sorting sorting device 40 through the second merging point.

[0091] The control device 10 controls the first conveying line 70 to convey the to-be-sorted goods to the first merging point, so as to merge with the to-be-sorted goods conveyed from the adjacent loading and unloading area to the first merging point, and obtain the first merged goods.

[0092] The control device 10 controls the first conveying line 70 to convey the first goods to the second merging point of the first loading and unloading area, so as to merge with the to-be-sorted goods conveyed from the pre-sorting and sorting device 40 to the second merging point, and obtain the second merged goods, and then the control device 10 controls the first conveying line 70 to convey the second merged goods to the final sorting and sorting device 30 in the first loading and unloading area, and the first conveying line 70 in the first loading and unloading area is connected to the sorting conveying line 60 of the pre-sorting and sorting device through the second merging point.

[0093] After the to-be-sorted goods in the first loading and unloading area are swung to the first conveying line 70 by the loading and unloading device 20, the control device 10 controls the first conveying line 70 to convey the to-be-sorted goods to the first merging point of the first conveying line 70. Since the first merging point is connected to the second conveying line 80 of the adjacent loading and unloading area, the to-be-sorted goods whose destination is the first loading and unloading area are also conveyed to the first merging point by the loading and unloading device 20 in the adjacent loading and unloading area through the second conveying line 80 of the adjacent loading and unloading area. Then, the to-be-sorted goods conveyed to the first merging point through the second conveying line 80 of the adjacent loading and unloading area are merged with the to-be-sorted goods conveyed to the first merging point through the first conveying line 70 in the first loading and unloading area, and the first merged goods are obtained.

[0094] After the to-be-sorted goods conveyed to the first merging point through the first conveying line 70 in the first loading and unloading area are merged with the to-be-sorted goods conveyed to the first merging point through the second conveying line 80 in the adjacent loading and unloading area, the first merged goods are obtained. Then, the control device 10 controls the first conveying line to convey the first merged goods to the final sorting and sorting device 30 in the first loading and unloading area. When the first merged goods are conveyed to the second merging point of the first conveying line 70, since the second merging point is connected to the sorting conveying line 60 of the pre-sorting and sorting device 40, the to-be-sorted goods whose destination is the first loading and unloading area are also conveyed to the second merging point by the pre-sorting and sorting device 40 through the sorting conveying line 60. Then, the to-be-sorted goods conveyed to the second merging point through the sorting conveying line 60 of the pre-sorting and sorting device 40 are merged with the to-be-sorted goods conveyed to the second merging point through the first conveying line 70 in the first loading and unloading area, and the second merged goods are obtained. The second merged goods are then conveyed to the final sorting and sorting device 30 in the first loading and unloading area.

[0095] In the embodiment, the final sorting device includes a sorting loop and a sorting machine arranged on the sorting loop. The process of sorting goods by the goods sorting system provided in the embodiment is exemplified below with two loading and unloading areas. As shown in the figure, the loading and unloading area A is set as the closest loading and unloading area to the loading and unloading area B, and the loading and unloading area B is also set as the closest loading and unloading area to the loading and unloading area A. The loading and unloading device at the unloading end of the loading and unloading area A transports the goods to be sorted to the sorting loop through the first transport line a, and transports the goods to be sorted to the sorting area through the sorting machine. The loading and unloading device at the unloading end of the loading and unloading area A is connected with the pre-sorting device through the pre-sorting transport line, and transports the goods to be sorted to the pre-sorting device through the pre-sorting transport line. The loading and unloading device at the unloading end of the loading and unloading area B transports the goods to be sorted to the sorting loop through the first transport line c, and transports the goods to be sorted to the sorting area through the sorting machine. The loading and unloading device at the unloading end of the loading and unloading area B is connected with the pre-sorting device through the pre-sorting transport line, and transports the goods to be sorted to the pre-sorting device through the pre-sorting transport line. The loading and unloading device at the unloading end of the loading and unloading area A transports the goods to be sorted to the loading and unloading area B through the second transport line a. Correspondingly, the loading and unloading device at the unloading end of the loading and unloading area B transports the goods to be sorted to the loading and unloading area A through the second transport line c. Figure 3

[0096] The first transport line a in the loading and unloading area A is connected with the second transport line c in the loading and unloading area B at the first merging point I1, and is connected with the sorting transport line at the second merging point M1. Correspondingly, the first transport line c in the loading and unloading area B is connected with the second transport line a in the loading and unloading area A at the first merging point I3, and is connected with the sorting transport line at the second merging point M3.

[0097] For the goods to be sorted unloaded at the loading and unloading area A, if the destination is the sorting area of the loading and unloading area A, the loading and unloading device of the loading and unloading area A swings the goods to be sorted to the first transport line a, and transports the goods to the sorting area of the loading and unloading area A through the first transport line a. If the destination is the sorting area of the loading and unloading area B, the loading and unloading device of the loading and unloading area A swings the goods to be sorted to the second transport line a, and transports the goods to the sorting area of the loading and unloading area B through the second transport line a. If the destination is other loading and unloading areas (loading and unloading areas other than the loading and unloading area A and the loading and unloading area B), the loading and unloading device of the loading and unloading area A swings the goods to be sorted to the pre-sorting transport line, and transports the goods to the pre-sorting device through the pre-sorting transport line. The pre-sorting device sorts the goods to be sorted, and transports the goods to the corresponding loading and unloading area.

[0098] ​For the to-be-sorted goods unloaded at the loading and unloading area B, if the destination is the sorting area of the loading and unloading area B, the loading and unloading device of the loading and unloading area B swings the to-be-sorted goods to the first transport line c and transports the to-be-sorted goods to the sorting area of the loading and unloading area B through the first transport line c. If the destination is the sorting area of the loading and unloading area A, the loading and unloading device of the loading and unloading area B swings the to-be-sorted goods to the second transport line c and transports the to-be-sorted goods to the sorting area of the loading and unloading area A through the second transport line c. If the destination is another loading and unloading area (a loading and unloading area other than the loading and unloading area A and the loading and unloading area B), the loading and unloading device of the loading and unloading area B swings the to-be-sorted goods to the pre-sorting transport line, transports the to-be-sorted goods to the pre-sorting device through the pre-sorting transport line, and sorts the to-be-sorted goods through the pre-sorting device to be transported to the corresponding loading and unloading area.

[0099] For the to-be-sorted goods whose destination is the sorting area of the loading and unloading area A, when transported to the first merging point I1 when transported to the sorting area of the loading and unloading area A through the first transport line a, the to-be-sorted goods are merged with the to-be-sorted goods transported to the sorting area 1 through the second transport line c in the loading and unloading area B. The merged goods continue to be transported to the sorting area, and when transported to the second merging point M1, the to-be-sorted goods are merged again with the to-be-sorted goods transported to the sorting area through the sorting transport line by the pre-sorting device. The to-be-sorted goods merged again continue to be transported until transported to the sorting area of the loading and unloading area A.

[0100] Correspondingly, the same process is used for the first transport line c in the loading and unloading area B, and details are not repeated here.

[0101] In order to improve the sorting capacity and maximize the sorting capacity of the final sorting device, the goods sorting system provided in the embodiment is provided with a plurality of guide-in areas and a plurality of sorting areas on the sorting loop of each loading and unloading area, and each guide-in area corresponds to a sorting area. For each sorting area, the to-be-sorted goods transported to the sorting area are first transported to the guide-in area corresponding to the sorting area, and then the to-be-sorted goods are guided into the guide-in area by the sorting trolley of the final sorting device and transported to the sorting area for sorting. In this way, when the sorting device reaches the next guide-in area, the sorting trolley is empty, the to-be-sorted goods in the next guide-in area can be guided in with the maximum guide-in capacity, and transported to the sorting area corresponding to the next guide-in area for sorting, so that the capacity of the final sorting device is maximized.

[0102] For example, as shown in FIG. 1, the goods sorting system provided in the embodiment is provided with a plurality of loading and unloading areas A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, and Z, and each loading and unloading area is provided with a sorting loop. Figure 4As shown, the sorting ring line of the loading and unloading area A is provided with a sorting area 1 and a sorting area 2, the corresponding guide-in area of the sorting area 1 is the guide-in area 1, the corresponding guide-in area of the sorting area 2 is the guide-in area 2, the loading and unloading equipment at the unloading end of the loading and unloading area A transports the to-be-sorted goods to the guide-in area 1 through the first transport line a, and then transports the to-be-sorted goods to the sorting area 1 through the sorting machine; the loading and unloading equipment at the unloading end of the loading and unloading area A transports the to-be-sorted goods to the guide-in area 2 through the first transport line b, and then transports the to-be-sorted goods to the sorting area 2 through the sorting machine.

[0103] The sorting ring line of the loading and unloading area B is provided with a sorting area 3 and a sorting area 4, the corresponding guide-in area of the sorting area 3 is the guide-in area 3, the corresponding guide-in area of the sorting area 4 is the guide-in area 4, the loading and unloading equipment at the unloading end of the loading and unloading area B transports the to-be-sorted goods to the guide-in area 3 through the first transport line c, and then transports the to-be-sorted goods to the sorting area 3 through the sorting machine; the loading and unloading equipment at the unloading end of the loading and unloading area B transports the to-be-sorted goods to the guide-in area 4 through the first transport line d, and then transports the to-be-sorted goods to the sorting area 4 through the sorting machine.

[0104] The loading and unloading equipment at the unloading end of the loading and unloading area A transports the to-be-sorted goods to the guide-in area 3 through the second transport line a, and then transports the to-be-sorted goods to the sorting area 3 through the sorting machine; the loading and unloading equipment at the unloading end of the loading and unloading area A transports the to-be-sorted goods to the guide-in area 4 through the second transport line b, and then transports the to-be-sorted goods to the sorting area 4 through the sorting machine. Correspondingly, the loading and unloading equipment at the unloading end of the loading and unloading area B transports the to-be-sorted goods to the guide-in area 1 through the second transport line c, and then transports the to-be-sorted goods to the sorting area 1 through the sorting machine; the loading and unloading equipment at the unloading end of the loading and unloading area B transports the to-be-sorted goods to the guide-in area 2 through the second transport line d, and then transports the to-be-sorted goods to the sorting area 2 through the sorting machine.

[0105] The first transport line a in the loading and unloading area A is connected with the second transport line c in the loading and unloading area B at the first confluence point I1, and is connected with the sorting transport line at the second confluence point M1; the first transport line b in the loading and unloading area A is connected with the second transport line d in the loading and unloading area B at the first confluence point I2, and is connected with the sorting transport line at the second confluence point M2. Correspondingly, the first transport line c in the loading and unloading area B is connected with the second transport line a in the loading and unloading area A at the first confluence point I3, and is connected with the sorting transport line at the second confluence point M3; the first transport line d in the loading and unloading area B is connected with the second transport line b in the loading and unloading area A at the first confluence point I4, and is connected with the sorting transport line at the second confluence point M4.

[0106] For the to-be-sorted goods unloaded in the loading and unloading area A and the destination is the sorting area 1 of the loading and unloading area A, the loading and unloading equipment of the loading and unloading area A swings the to-be-sorted goods to the first transport line a and transports the to-be-sorted goods to the sorting area 1 through the first transport line a. If the destination is the sorting area 2 of the loading and unloading area A, the loading and unloading equipment of the loading and unloading area A swings the to-be-sorted goods to the first transport line b and transports the to-be-sorted goods to the sorting area 2 through the first transport line b. If the destination is the sorting area 3 of the loading and unloading area B, the loading and unloading equipment of the loading and unloading area A swings the to-be-sorted goods to the second transport line a and transports the to-be-sorted goods to the sorting area 3 through the second transport line a. If the destination is the sorting area 4 of the loading and unloading area B, the loading and unloading equipment of the loading and unloading area A swings the to-be-sorted goods to the second transport line b and transports the to-be-sorted goods to the sorting area 4 through the second transport line b. If the destination is other loading and unloading area (loading and unloading area other than the loading and unloading area A and the loading and unloading area B), the loading and unloading equipment of the loading and unloading area A swings the to-be-sorted goods to the pre-sorting transport line and transports the to-be-sorted goods to the pre-sorting sorting equipment through the pre-sorting transport line, and the to-be-sorted goods are pre-sorted by the pre-sorting sorting equipment and transported to the corresponding loading and unloading area.

[0107] For the to-be-sorted goods whose destination is the sorting area 1 of the loading and unloading area A and are transported to the sorting area 1 through the first transport line a, the to-be-sorted goods are merged with the to-be-sorted goods transported to the sorting area 1 through the second transport line c in the loading and unloading area B when transported to the first merging point I1. The merged goods continue to be transported to the sorting area 1, and are merged again with the to-be-sorted goods transported to the sorting area 1 through the sorting transport line by the pre-sorting sorting equipment when transported to the second merging point M1. The to-be-sorted goods continue to be transported until transported to the introduction area 1. For the to-be-sorted goods whose destination is the sorting area 2 of the loading and unloading area A, the to-be-sorted goods are transported to the introduction area 2 through the corresponding process. When the to-be-sorted goods are transported to the introduction area, the sorting machine can first introduce the to-be-sorted goods to the introduction area 1, then transport the to-be-sorted goods to the sorting area 1, sort all the introduced to-be-sorted goods in the sorting area 1, then reach the introduction area 2 in an empty state, introduce the to-be-sorted goods in the introduction area 2, and transport the to-be-sorted goods to the sorting area 2. All the introduced to-be-sorted goods in the sorting area 1 are sorted, and the sorting machine continues to reach the introduction area 1 in an empty state, introduces the to-be-sorted goods, and so on, until all the to-be-sorted goods are sorted. In this way, the sorting equipment can be in an empty state when reaching each introduction area, can introduce goods with maximum capacity, and can improve the sorting capacity.

[0108] It can be understood that the to-be-sorted goods in other loading and unloading areas are sorted through the same process, which will not be described in detail here.

[0109] To prevent the pre-sorting equipment from blocking the goods transported to the second confluence point via the sorting transport line after being transported to the second confluence point, in this embodiment, the goods sorting system includes a first separation device and a second separation device. The first separation device is located between the pre-sorting equipment and the second confluence point, and the second separation device is located between the second confluence point and the final sorting equipment.

[0110] The first separation device is used to separate the goods to be sorted from the pre-sorting device to the first separation device into goods to be merged and goods to be introduced, transport the goods to be merged to the second merging point for merging, and transport the goods to be introduced to the final sorting device in the sorting area of ​​the first loading and unloading area.

[0111] The second separation device is used to divide the second goods after merging at the second confluence point into multiple routes for final sorting in the sorting area of ​​the first loading and unloading area.

[0112] The first and second separation devices can be swing wheels. The first separation device is set before the second merging point, that is, between the pre-sorting device and the second merging point, and is used to separate the goods to be sorted that have not merged. The second separation device is set after the second merging point, that is, between the second merging point and the final sorting device, and is used to separate the goods to be sorted after merging.

[0113] like Figure 5 As shown, for loading and unloading area A, when goods to be sorted are transported by the pre-sorting equipment via the sorting transport line to the first separation equipment, the first separation equipment can separate the goods to be sorted from the pre-sorting equipment into goods to be merged and goods to be introduced. The goods to be introduced are directly transported to the introduction area, while the goods to be merged are further transported to the second merging point, where they merge with the goods to be sorted transported to the second merging point via the first transport line to obtain the second goods. The merged second goods continue to be transported to the introduction area via the first transport line. When transported to the second separation equipment, the second separation equipment can divide the merged second goods into multiple routes, which are then transported to the introduction area in multiple routes. Correspondingly, the same sorting process applies to other loading and unloading areas, and will not be elaborated further here.

[0114] This embodiment sets up a first separation device before the second merging point and a second separation device after the second merging point. The first separation device separates the goods to be sorted from the pre-sorting equipment, reducing the flow of the sorting transport line and avoiding blockage. The second separation device separates the goods after merging, avoiding blockage on the transport line to the inlet area and improving sorting capacity.

[0115] In an optional embodiment, the first separating device and the second separating device can separate the goods to be sorted according to the transport sequence of the goods, for example, for the first separating device, the first goods on the sorting transport line can be separated to the transport line directly transporting to the introduction area first, then the next goods can be separated to the second merging point, and the next goods can be separated to the transport line directly transporting to the introduction area, and so on. Correspondingly, for the second separating device, the same separation mode can also be adopted, which will not be described herein.

[0116] In an optional embodiment, the first separating device and the second separating device can also separate the goods to be sorted according to a set time period, for example, for the first separating device, the goods to be sorted on the sorting transport line can be separated to the transport line directly transporting to the introduction area in the first set time period, then the goods to be sorted on the sorting transport line can be separated to the second merging point in the second set time period, and the goods to be sorted on the sorting transport line can be separated to the transport line directly transporting to the introduction area in the third set time period, and so on. Correspondingly, for the second separating device, the same separation mode can also be adopted, which will not be described herein.

[0117] In this embodiment, after the goods to be sorted are merged at the second merging point, the obtained goods are bulk flow, and therefore, the single-piece separator can be arranged in the introduction area to separate the merged goods into single-piece flow, and then the single-piece flow is transported to the introduction area.

[0118] The goods sorting system provided in this embodiment can separate the goods to be sorted according to the local unloading area and the nearest adjacent unloading area by arranging the first transport line between the final sorting device and the unloading device in each unloading area, and arranging the second transport line between the unloading device in each unloading area and the final sorting device in the nearest adjacent unloading area. For the goods to be sorted belonging to the local unloading area and the nearest adjacent unloading area, the goods can be sorted without being transported to the pre-sorting device for pre-sorting, thereby improving the sorting efficiency of the local unloading area and the nearest adjacent unloading area, simplifying the sorting process, reducing the probability of pre-sorting device blockage, and improving the overall efficiency of the goods sorting system. Meanwhile, the pre-sorting capacity of the goods sorting system is increased, and the increased pre-sorting capacity is equal to the amount of goods placed in the local unloading area and the nearest adjacent unloading area.

[0119] For example, there are N unloading areas (N is generally greater than or equal to 4 and is an even number), and the destination flow of the goods is completely randomly distributed in the N unloading areas. The goods with the destination flow in the “local unloading area” and the “nearest adjacent unloading area” can be sorted to the corresponding destination through the shortcut line such as the first transport line and the second transport line, and therefore, there are:

[0120] The increased pre-sorting capacity of the first transport line or the second transport line provided by the N loading and unloading areas = (1 / N) × the capacity of a single final-sorting sorting device × N.

[0121] The increased pre-sorting capacity of the first transport line and the second transport line provided by the N loading and unloading areas simultaneously = 2 ×

[0122] (1 / N) × the capacity of a single final-sorting sorting device × N.

[0123] Taking the processing capacity of 20,000 pieces / hour of the universal sorting machine 2 as an example, the first transport line or the second transport line is provided alone, and theoretically the system pre-sorting capacity can be improved by 20,000 pieces / hour; the first transport line and the second transport line are provided simultaneously, and the system pre-sorting capacity can be improved by 40,000 pieces / hour.

[0124] Based on the same inventive concept, the embodiment also provides a goods sorting method. The goods sorting method provided by the embodiment is applied to the control device in the goods sorting system as shown in the Figure 1 As shown in the Figure 6 As shown in the Figure 6 The control device 10 includes a goods sorting apparatus 101, a memory 102, a processor 103, and a communication unit 104. The memory 102, the processor 103, and the communication unit 104 are electrically connected to each other directly or indirectly to realize the transmission or interaction of signals. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines.

[0125] In the embodiment, the goods sorting apparatus 101 includes at least one software function module that can be stored in the memory 102 in the form of software or firmware. The processor 103 is configured to execute the executable modules (for example, the software function modules or computer programs included in the goods sorting apparatus 101) stored in the memory 102. When the control device 10 is running, the processor 103 and the memory 102 communicate through a bus. The processor 103 executes the executable modules or computer programs to realize the goods sorting method described in the embodiment.

[0126] The communication unit 104 is configured to establish a communication connection between the control device 10 and other devices through a network, and is configured to transmit and receive data through the network.

[0127] In the embodiment, the control device 10 can be a notebook computer, an ultra-mobile personal computer (UMPC), a physical server, or the like. The embodiment does not limit the specific type of the control device.

[0128] It can be understood that Figure 6 The structure shown in the The control device 10 can also have more or fewer elements than those shown in theFigure 6 more or less components, or with different configurations of the components Figure 6 shown. Figure 6 The components shown can be implemented in hardware, software, or a combination thereof.

[0129] Based on Figures 1 to 6 The implementation architecture shown, the embodiment provides a cargo sorting method, which is executed by a control device. The steps of the cargo sorting method provided by the embodiment are described in detail below. Please refer to Figure 7 The cargo sorting method provided by the embodiment includes steps S101 to S104.

[0130] Step S101: Obtain destination information of the cargo to be sorted, and determine a first loading and unloading area for unloading the cargo to be sorted.

[0131] The cargo to be sorted is provided with an identification code, and the identification code records the destination information of the cargo to be sorted. The embodiment can be provided with a scanning device, which can be electrically connected or communicatively connected to the control device. The scanning device can scan the identification code on the cargo to be sorted to obtain the destination information of the cargo to be sorted. After obtaining the destination information of the cargo to be sorted, the scanning device can transmit the destination information of the cargo to be sorted to the control device, and the control device can obtain the destination information of the cargo to be sorted.

[0132] In an optional embodiment, when determining the first loading and unloading area for unloading the cargo to be sorted, an arbitrary loading and unloading area can be designated as the first loading and unloading area for unloading the cargo to be sorted.

[0133] In order to improve the sorting efficiency, in the embodiment, the step of determining the first loading and unloading area for loading and unloading the cargo to be sorted can include:

[0134] According to the destination information of the cargo to be sorted, determine the proportion of the cargo flowing to each destination, and determine the first loading and unloading area according to the destination corresponding to the maximum proportion of the cargo.

[0135] For example, in the cargo to be sorted, 50% of the cargo goes to destination A, 20% to destination B, 10% to destination C, 10% to destination D, 5% to destination E, and 5% to destination F, wherein the proportion of the cargo to destination A is the largest, and the loading and unloading area corresponding to destination A is set as the first loading and unloading area, and the batch of cargo to be sorted is transported to the loading and unloading area corresponding to destination A, and unloaded by the loading and unloading module of the loading and unloading area corresponding to destination A.

[0136] After determining the first loading and unloading area for unloading the cargo to be sorted, the cargo to be sorted can be transported to the first loading and unloading area, and the loading and unloading device at the unloading end of the first loading and unloading area can unload the cargo to be sorted.

[0137] Step S102: detecting whether the destination information of the to-be-sorted goods belongs to the first loading and unloading area. If it belongs to the first loading and unloading area, step S103 is executed, and if it does not belong to the first loading and unloading area, step S104 is executed.

[0138] After the to-be-sorted goods are transported to the first loading and unloading area for unloading, for each to-be-sorted goods, it is detected whether the destination information of the to-be-sorted goods belongs to the first loading and unloading area, that is, whether the destination of the to-be-sorted goods is the first loading and unloading area. If the destination information of the to-be-sorted goods belongs to the first loading and unloading area, it indicates that the to-be-sorted goods are finally sorted in the first loading and unloading area, and step S103 is executed. If the destination information of the to-be-sorted goods does not belong to the first loading and unloading area, it indicates that the to-be-sorted goods are not finally sorted in the first loading and unloading area, and step S104 is executed.

[0139] Step S103: controlling the to-be-sorted goods to be transported to the final sorting device of the first loading and unloading area.

[0140] When the to-be-sorted goods are finally sorted in the first loading and unloading area, the control device can issue a first control instruction to the loading and unloading device of the first loading and unloading area. After receiving the first control instruction, the loading and unloading device responds to the first control instruction and swings the to-be-sorted goods to the first transport line, that is, sorts the to-be-sorted goods to the first transport line, directly transports the to-be-sorted goods to the final sorting device of the first loading and unloading area through the first transport line, and directly sorts the to-be-sorted goods by the final sorting device of the first loading and unloading area.

[0141] Step S104: controlling the to-be-sorted goods to be transported to the pre-sorting device, and sorting the to-be-sorted goods by the pre-sorting device.

[0142] When the to-be-sorted goods are not finally sorted in the first loading and unloading area, the control device can issue a second control instruction to the loading and unloading device of the first loading and unloading area. After receiving the second control instruction, the loading and unloading device responds to the second control instruction and swings the to-be-sorted goods to the pre-sorting transport line, transports the to-be-sorted goods to the pre-sorting device through the pre-sorting transport line, and sorts the to-be-sorted goods by the pre-sorting device.

[0143] The goods sorting method provided by the embodiment comprises the following steps: a first conveying line is arranged between a terminal sorting device and a loading and unloading device in each loading and unloading area; after destination information of a to-be-sorted goods is obtained and a first loading and unloading area where the to-be-sorted goods is unloaded is determined, it is detected whether the destination information of the to-be-sorted goods belongs to the first loading and unloading area; if the destination information belongs to the first loading and unloading area, the to-be-sorted goods is directly conveyed to the terminal sorting device of the first loading and unloading area through the loading and unloading device of the first loading and unloading area; if the destination information does not belong to the first loading and unloading area, the to-be-sorted goods is conveyed to a pre-sorting device through the loading and unloading device of the first loading and unloading area, and the to-be-sorted goods is sorted by the pre-sorting device. In this way, by determining the destination information of the to-be-sorted goods, the to-be-sorted goods belonging to the first loading and unloading area is directly conveyed to the terminal sorting device of the first loading and unloading area without pre-sorting by the pre-sorting device, so that the probability of pre-sorting device congestion is effectively reduced, the sorting process is simplified, and the sorting efficiency is improved.

[0144] In order to further improve the efficiency of goods sorting, simplify the sorting process and reduce the sorting cost, a second conveying line is arranged between the loading and unloading device of each loading and unloading area and the terminal sorting device of the loading and unloading area closest to the loading and unloading area. Based on this, if the destination information does not belong to the first loading and unloading area, the step of conveying the to-be-sorted goods to the pre-sorting device can further comprise the following steps:

[0145] determining a second loading and unloading area closest to the first loading and unloading area, and detecting whether the destination information of the to-be-sorted goods belongs to the second loading and unloading area.

[0146] if the destination information belongs to the second loading and unloading area, conveying the to-be-sorted goods to the terminal sorting device of the second loading and unloading area.

[0147] if the destination information does not belong to the second loading and unloading area, conveying the to-be-sorted goods to the pre-sorting device.

[0148] The control device can pre-acquire position information of each loading and unloading area, for each loading and unloading area, determine a target loading and unloading area closest to the loading and unloading area according to the position information of the loading and unloading area and the position information of other loading and unloading areas, and then establish a position relationship between each loading and unloading area and the target loading and unloading area closest to the loading and unloading area, so as to obtain position relationship data according to the position relationship of each loading and unloading area. After obtaining the position relationship data, the second loading and unloading area closest to the first loading and unloading area can be determined according to the position relationship data.

[0149] Optionally, in the position relationship data, the first loading and unloading area is found, and the second loading and unloading area closest to the first loading and unloading area is determined according to the position relationship of the first loading and unloading area.

[0150] After determining the second loading and unloading area closest to the first loading and unloading area, for the to-be-sorted goods, if the destination of the to-be-sorted goods does not belong to the first loading and unloading area, it is detected whether the destination information of the to-be-sorted goods belongs to the second loading and unloading area, if the destination information of the to-be-sorted goods belongs to the second loading and unloading area, it is indicated that the to-be-sorted goods is subjected to final sorting in the second loading and unloading area, and if the destination information of the to-be-sorted goods does not belong to the second loading and unloading area, it is indicated that the to-be-sorted goods is not subjected to final sorting in the second loading and unloading area.

[0151] Optionally, when the to-be-sorted goods is subjected to final sorting in the second loading and unloading area, the control device can issue a third control instruction to the loading and unloading device of the first loading and unloading area, and the loading and unloading device, after receiving the third control instruction, swings the to-be-sorted goods to the second transport line in response to the third control instruction, that is, the to-be-sorted goods is sorted to the first transport line, and the to-be-sorted goods is directly transported to the final sorting device of the second loading and unloading area through the second transport line, and the to-be-sorted goods is directly sorted by the final sorting device of the second loading and unloading area.

[0152] When the to-be-sorted goods is not subjected to final sorting in the first loading and unloading area and is not subjected to final sorting in the second loading and unloading area, the control device can issue a second control instruction to the loading and unloading device of the first loading and unloading area, and the loading and unloading device, after receiving the second control instruction, swings the to-be-sorted goods to the pre-sorting transport line in response to the second control instruction, and the to-be-sorted goods is transported to the pre-sorting device through the pre-sorting transport line, and the to-be-sorted goods is sorted by the pre-sorting device.

[0153] In order to facilitate sorting of the to-be-sorted goods transported from the closest loading and unloading area and the to-be-sorted goods transported from the pre-sorting device, in the embodiment, the first transport line of each loading and unloading area is provided with a first merging point and a second merging point, the first transport line of each loading and unloading area is connected with the second transport line of the loading and unloading area taking the loading and unloading area as the second loading and unloading area through the first merging point, and is connected with the sorting transport line of the pre-sorting device through the second merging point.

[0154] Based on this, in the embodiment, the step of controlling the to-be-sorted goods to be transported to the final sorting device of the first loading and unloading area can include:

[0155] The to-be-sorted goods is controlled to be transported to the first merging point of the first loading and unloading area to merge with the to-be-sorted goods transported from the adjacent loading and unloading area to the first merging point, to obtain the first goods after merging; the adjacent loading and unloading area represents the loading and unloading area taking the first loading and unloading area as the second loading and unloading area.

[0156] The first goods is controlled to be transported to the second merging point of the first loading and unloading area to merge with the to-be-sorted goods transported from the pre-sorting device to the second merging point, to obtain the second goods after merging.

[0157] control the second goods to be transported to the terminal sorting device of the first unloading area.

[0158] Wherein, after the control device controls the unloading device to transport the goods to be sorted through the first transport line to the first unloading area, the first merging point is connected with the second transport line of the adjacent unloading area, so that the goods to be sorted with the destination of the first unloading area are also transported by the unloading device of the adjacent unloading area through the second transport line of the adjacent unloading area to the first merging point, and then the goods to be sorted transported through the second transport line of the adjacent unloading area to the first merging point are merged with the goods to be sorted transported through the first transport line of the first unloading area to the first merging point, to obtain the first merged goods.

[0159] After obtaining the first merged goods, the control device continues to control the first transport line to transport the first merged goods to the terminal sorting device of the first unloading area, and when transported to the second merging point of the first transport line, the second merging point is connected with the sorting transport line of the pre-sorting device, so that the goods to be sorted with the destination of the first unloading area are also transported by the pre-sorting device through the sorting transport line to the second merging point, and then the goods to be sorted transported through the sorting transport line of the pre-sorting device to the second merging point are merged with the goods to be sorted transported through the first transport line of the first unloading area to the second merging point, to obtain the second merged goods, and the second merged goods are continuously transported to the terminal sorting device in the first unloading area. For details, refer to the sorting process of the goods sorting system, which will not be described here.

[0160] In view of the fact that the sorting capacity of each sorting device has an upper limit in actual application, in order to reduce congestion when sorting in the unloading area, in this embodiment, the step of controlling the goods to be sorted to be transported to the terminal sorting device of the first unloading area can further include:

[0161] detecting whether the carrying capacity of the terminal sorting device of the first unloading area reaches a set carrying threshold.

[0162] If the set carrying threshold is reached, detecting whether the goods to be sorted have an urgent identifier.

[0163] If the goods to be sorted have an urgent identifier, the goods to be sorted are controlled to be transported to the terminal sorting device of the first unloading area.

[0164] If the goods to be sorted do not have an urgent identifier, the goods to be sorted are controlled to be transported to the pre-sorting device.

[0165] The control device can detect whether the carrying capacity of the final sorting device in the first loading and unloading area reaches a set carrying threshold, i.e., whether the sorting capacity of the final sorting device in the first loading and unloading area is greater than the set carrying threshold, before controlling the to-be-sorted goods to be transported to the final sorting device in the first loading and unloading area.

[0166] Optionally, in this embodiment, the set carrying threshold can be 80% of the maximum sorting capacity of the final sorting device or other set proportion. When the carrying capacity of the final sorting device reaches the set carrying threshold, it indicates that the sorting capacity of the final sorting device is about to reach the maximum. At this time, if a large amount of to-be-sorted goods is directly transported to the final sorting device, congestion of the final sorting device can occur. When the carrying capacity of the final sorting device does not reach the set carrying threshold, it indicates that the sorting capacity of the final sorting device has a surplus, and the to-be-sorted goods can be directly transported to the final sorting device.

[0167] Based on this, in this embodiment, when the carrying capacity of the final sorting device reaches the set carrying threshold, it can be detected whether the to-be-sorted goods have an urgent identifier. If the to-be-sorted goods have the urgent identifier, it indicates that the to-be-sorted goods are urgently needed to be sorted, and therefore, the to-be-sorted goods can be controlled to be directly transported to the final sorting device in the first loading and unloading area through the first transport line, reducing the process of going to the pre-sorting device and reducing the sorting time. When the to-be-sorted goods do not have the urgent identifier, the to-be-sorted goods can be controlled to be transported to the pre-sorting device through the pre-sorting transport line, and the pre-sorting device can transport the to-be-sorted goods to the final sorting device in the first loading and unloading area. In this way, by increasing the process of going to the pre-sorting device and reducing the flow of goods directly transported to the final sorting device, congestion during sorting in the loading and unloading area is reduced.

[0168] It can be understood that when the carrying capacity of the final sorting device does not reach the set carrying threshold, whether the to-be-sorted goods have the urgent identifier or not, the to-be-sorted goods can be directly transported to the final sorting device through the first transport line.

[0169] The goods sorting method provided by the embodiment, by setting the first transport line between the final sorting device and the loading and unloading device in each loading and unloading area, and setting the second transport line between the loading and unloading device in each loading and unloading area and the final sorting device in the nearest loading and unloading area, thus, by setting the fast transport line between the local loading and unloading area and the nearest adjacent loading and unloading area, for the goods to be sorted belonging to the local loading and unloading area and the adjacent loading and unloading area, the goods can be sorted without being transported to the pre-sorting device for pre-sorting, the sorting efficiency of the goods in the local loading and unloading area and the adjacent loading and unloading area is improved, the sorting process is simplified, the probability of pre-sorting device blockage is reduced, and the overall efficiency of the goods sorting system is improved. Meanwhile, the pre-sorting capacity of the goods sorting system is also increased, and the increased pre-sorting capacity is equal to the amount of goods placed in the local loading and unloading area and the adjacent loading and unloading area.
