Description

Technical Field

[0001] This invention relates to the technical field of automated logistics transportation, and in particular to an aviation irregular-shaped parcel sorting system and sorting method. Background Technology

[0002] In recent years, with the rapid development of the logistics industry, the development of logistics equipment has been promoted. Regular parcels can be sorted quickly by automated systems. However, due to the irregular size of irregular-shaped parcels, automated sorting equipment cannot be compatible with sorting irregular-shaped parcels. Therefore, manual sorting is used to sort irregular-shaped parcels. Currently, there are sorting systems on the market that can sort irregularly sized packages, such as the sorting system with publication number CN216420221U. Although this structure can transport irregularly shaped packages to the main conveyor for merging via multiple branch conveyors, and then the sorting module belts sort the irregularly shaped packages on the main conveyor onto the corresponding sorting conveyor to achieve automatic sorting of irregularly shaped packages, this sorting method is only suitable for sorting irregularly shaped packages on a single sorting line. It cannot achieve sorting of multiple sorting lines simultaneously, that is, sorting irregularly shaped packages from other sorting lines to the current sorting line, or transporting irregularly shaped packages from the current sorting line to other sorting lines. Therefore, manual transfer of irregularly shaped packages to other sorting lines is still required. In addition, since packages may be stacked during transportation, and the above sorting system cannot separate stacked packages, manual sorting of stacked packages is still required during the sorting process. This not only increases the labor intensity of workers, but also greatly reduces sorting efficiency. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide an air cargo irregular shape parcel sorting system and sorting method, which realizes automatic sorting of irregularly shaped parcels and multi-island joint sorting, greatly improving the sorting efficiency of air cargo parcels, reducing the labor intensity of operators, and saving labor costs.

[0004] To achieve the above objectives, the present invention discloses an aviation irregular package sorting system, including an aviation box conveying unit, an irregular package conveying unit, and an irregular package sorting unit. The aviation box conveying unit is arranged around the irregular package conveying unit and the irregular package sorting unit. The irregular package conveying unit is used to send the irregular packages on the aviation box conveying unit one by one into the irregular package sorting unit for sorting.

[0005] The flight case conveying unit includes several omnidirectional wheels, several unloading platforms, several packing platforms, and aisles. The rectangular array of several omnidirectional wheels is set as a square turnover area. The several unloading platforms are set between the omnidirectional wheels and the regular parcel conveying unit and the irregular parcel conveying unit. The several packing platforms are respectively set between the omnidirectional wheels and the several irregular parcel sorting units. The aisle is set on one side of the several unloading platforms and the several packing platforms.

[0006] The irregular package sorting unit includes a first sorting section, a multi-island conveyor sorting section, a second sorting section, a multiple sorting section, and a modular belt sorting section. The conveyor section is located between the unpacking station and the first sorting section. The second sorting section is located between the first sorting section and the multiple sorting sections. The multi-island conveyor sorting section is located between the first sorting section and the second sorting section. The modular belt sorting sections are located between the packing station and the multiple sorting sections.

[0007] Furthermore, the first sorting section includes a first single-piece separation conveyor, a first central conveyor, a first disc sorter, a first side-mounting machine, a plurality of first rotating roller machines, and a first sorting conveyor line. The first central conveyor is located between the first single-piece separation conveyor and the first disc sorter. The first sorting conveyor line is located between the first disc sorter and the second sorting section. The first side-mounting machine is vertically located on the side of the first disc sorter. The plurality of first rotating roller machines are respectively vertically located on the side of the first side-mounting machine.

[0008] Furthermore, the multi-island conveying and sorting section includes a first lifting conveyor, an input multi-layer conveyor, an elevator, an output multi-layer conveyor, and a second lifting conveyor. The first lifting conveyor is vertically and vertically disposed between the first tilting roller and the input multi-layer conveyor. The elevator is disposed between the input multi-layer conveyor and the output multi-layer conveyor. The second lifting conveyor is vertically and vertically disposed between the output multi-layer conveyor and the second sorting section.

[0009] Furthermore, the second sorting section includes several second rotating roller machines, a first belt conveyor line, a second sorting conveyor line, a second single-piece separation conveyor, and a second centralizing conveyor. The second sorting conveyor line is located at the end of the first sorting section, the second single-piece separation conveyor is located at the end of the second sorting conveyor line, and the second centralizing conveyor is located between the second single-piece separation conveyor and the multiple sorting sections. The first belt conveyor line is vertically arranged on one side of the second sorting conveyor line, and the several second rotating roller machines are respectively vertically arranged on the side of the first belt conveyor line.

[0010] Furthermore, the multiple sorting section includes a second disc sorter, a second belt conveyor, a box-packing waiting conveyor, a queuing waiting line, a return sorting line, a return roller machine, and a parcel collection section. The second disc sorter is located between the second sorting section and the parcel collection section. The second belt conveyor is located on one side of the second disc sorter. The box-packing waiting conveyor is located between the second belt conveyor and the box-packing table. The queuing waiting line and the return sorting line are respectively vertically arranged on one side of the second belt conveyor. The return roller machine is located at the end of the return sorting line.

[0011] Furthermore, the modular belt sorting section includes a modular belt sorter, a boxing conveyor line, and a parcel recycling conveyor line. The modular belt sorter is located at the end of the return sorting line, the boxing conveyor line is vertically arranged on one side of the modular belt sorter, and the parcel recycling conveyor line is located at the end of the modular belt sorter.

[0012] Furthermore, the modular belt sorting machine includes a double-layer modular belt and a lifting mechanism. The double-layer modular belt drives irregularly shaped packages toward the return sorting line, or the double-layer modular belt moves irregularly shaped packages toward the packing conveyor line under the action of the lifting mechanism.

[0013] Furthermore, the packing conveyor line is equipped with a foot-operated conveyor button, which is used to start or stop the packing conveyor line.

[0014] Furthermore, the double-layer modular belt includes an upper inclined ball conveyor belt, a lower ball conveyor belt, and a fixed frame. The upper inclined ball conveyor belt and the lower ball conveyor belt are tensioned on the fixed frame. The balls of the lower ball conveyor belt are in contact with the inclined balls of the upper inclined ball conveyor belt, and the upper inclined ball conveyor belt and the lower ball conveyor belt are conveyed synchronously.

[0015] Furthermore, the lifting mechanism includes a non-powered roller conveyor and a base. The base is fixedly installed within the fixed frame, and the non-powered roller conveyor is vertically and vertically positioned above the base. When the non-powered roller conveyor rises, it contacts the balls of the lower ball conveyor belt. As the upper inclined ball conveyor belt and the lower ball conveyor belt move forward, the balls of the lower ball conveyor belt drive the inclined balls of the upper inclined ball conveyor belt to rotate under the friction of the non-powered roller conveyor, thus feeding the package into the packing conveyor line in a specified direction.

[0016] The present invention also provides a sorting method for an aviation irregularly shaped package sorting system, comprising the following steps:

[0017] S100: Several universal wheels transfer the flight container to the unpacking platform, where staff remove the irregularly shaped packages from the flight container and send them to the irregularly shaped package conveying unit.

[0018] S101, Several conveyor lines of the irregular package conveying unit will merge the irregular packages on the corresponding unpacking platform into the main line, so that the main line will send the irregular packages one by one into the first sorting section.

[0019] S102. The irregularly shaped packages in the stacked state on the main line are mechanically separated by the first single-piece separation conveyor, and the separated irregularly shaped packages are sent one by one to the first disc sorter by the first centering conveyor. The first disc sorter sends the packages to the second sorting or multi-island conveyor sorting section according to the information of the irregularly shaped packages.

[0020] S103. The second sorting conveyor line sends the irregularly shaped packages on the first sorting section into the second single-piece separation conveyor for further separation, and then sends the irregularly shaped packages sent out from the second single-piece separation machine into the multiple sorting section through the second centering conveyor.

[0021] S104. The second disc sorter on the multiple sorting section sends the irregularly shaped packages into the second belt conveyor line, which then sends the irregularly shaped packages one by one into the packing waiting conveyor line. The staff then pack the packages on the packing waiting line into the flight cases on the packing table.

[0022] S105. Packages that fail to be sorted or are abnormal on the second belt conveyor line are returned to the return sorting line and sorted manually.

[0023] S106. When the sorting of irregularly shaped packages on the second belt conveyor line cannot be processed in time, the second belt conveyor will send the corresponding irregularly shaped package to the queuing line 344, so that the queuing line will send the package to the module belt sorting section.

[0024] S107. Irregularly shaped packages that cannot be processed in time are sent to the packing conveyor line by the modular belt sorter, so that the packing conveyor line sends the irregularly shaped packages to the packing table for packing. Packages that fail to be sorted or are abnormal are sent to the package recycling line for return through the modular belt sorter.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] (1) The irregular package sorting system can improve the sorting efficiency of irregular packages and reduce the labor intensity of operators by automating the sorting of sections such as the conveyor section, the first sorting section, the multi-island conveyor sorting section, the second sorting section, the multiple sorting section and the module belt sorting section. (2) The system adopts the method of multi-island joint sorting, sorting packages from other islands through the intelligent tray sorting system, thereby improving the multi-island sorting efficiency.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the following will be combined with... Figures 1-11 The invention will be further described in detail with reference to the accompanying drawings.

[0039] Reference Figure 1 As shown, an air cargo sorting system for irregularly shaped parcels includes an air cargo container conveying unit 1, an irregularly shaped parcel conveying unit 2, and an irregularly shaped parcel sorting unit 3. The air cargo container unit 1 is arranged around the irregularly shaped parcel conveying unit 2 and the irregularly shaped parcel sorting unit 3. The irregularly shaped parcel conveying unit 2 is used to send the irregularly shaped parcels on the air cargo container conveying unit 1 one by one into the irregularly shaped parcel sorting unit 3 for sorting. Then, the irregularly shaped parcel sorting unit 3 sends the sorted parcels onto the air cargo container conveying unit 1 for packing.

[0040] The flight case conveying unit 1 includes several omnidirectional wheel platforms 11, several unpacking platforms 12, several packing platforms 13, and aisles 14. In this embodiment, the several omnidirectional wheel platforms 11 form a square turnover area. The several unpacking platforms 12 are arranged between the omnidirectional wheel platforms 11 and the irregular package conveying unit 2. The several packing platforms 13 are respectively arranged between the omnidirectional wheel platforms 11 and the irregular package sorting unit 3. The aisle 14 is arranged on one side of the several unpacking platforms 12 and packing platforms 13, so that the omnidirectional wheel platforms 11 can send the flight cases into the corresponding unpacking platforms 12 and packing platforms 13, which makes it convenient for the staff to unpack the flight cases on the unpacking platforms 12 or put the sorted packages into the flight cases on the packing platforms 13 on the aisle 14.

[0041] Reference Figure 1 , Figure 2 As shown, the irregular package conveying unit 2 includes several conveyor lines 21, several waiting lines 22, a main line 23, and a guiding device 24. The waiting lines 22 are respectively arranged between the conveyor lines 21 and the main line 23, and the guiding device 24 is arranged on the main line 23. In this embodiment, the conveyor lines, waiting lines, and main line are preferably belt conveyors. The guiding device 24 includes several pairs of first side plates and second side plates. The first and second side plates are respectively fixedly arranged on both sides of the main line 23 along the conveying direction of the package, and the front and rear ends of the first and second side plates are flared to center the irregular packages on the main line under the guidance of the guiding device 24 and to prevent the irregular packages from sliding off the main line. Several package detection modules are respectively arranged above the main line 23 corresponding to the waiting lines 22. In this embodiment, the package detection modules can be infrared sensors, photoelectric sensors, cameras, etc., to detect whether there are packages on the main line 23 and feed back to the waiting lines 22.

[0042] In practice, irregularly shaped packages on the unloading platform 12 are sent to the waiting line 22 via the conveyor line 21. The package detection module detects whether there are packages at the position of the main line 23 corresponding to the waiting line 22. When a package is detected, the waiting line 22 stops conveying. If no package is detected, the waiting line 22 sends the irregularly shaped package to the main line 23 according to the detection status of the package detection module, so that the irregularly shaped packages are sent into the irregularly shaped package sorting unit 3 for sorting in an orderly manner.

[0043] Reference Figure 1 , Figure 3As shown, the irregular package sorting unit 3 includes a first sorting section 31, a multi-island conveyor sorting section 32, a second sorting section 33, a multiple sorting section 34, and a module belt sorting section 35. The main line 23 is located between the unloading platform 12 and the first sorting section 31. The second sorting section 33 is located between the first sorting section 31 and the multiple sorting section 34. The multi-island conveyor sorting section 32 is located between the first sorting section 31 and the second sorting section 33. The module belt sorting section 35 is located between the packing platform 13 and the multiple sorting section 34. Irregular packages in the flight case are manually fed onto the main line 23 so that the main line 23 conveys the irregular packages one by one to the first sorting section 31. The irregular packages are then sent to the multi-island conveyor sorting section 32 or the second sorting section 33 through the first sorting section 31, completing the initial sorting of the irregular packages.

[0044] Combination Figure 3 , Figure 4 As shown, the first sorting section 31 includes a first single-piece separation conveyor 311, a first central conveyor 312, a first disc sorter 313, a first edge-adjusting machine 314, a first rotating roller machine 315, and a first sorting conveyor line 316. The first single-piece separation conveyor 311 is located at the end of the main line 23. The first central conveyor 312 is located between the first single-piece separation conveyor 311 and the first disc sorter 313, and a six-sided scanning device is installed above the first central conveyor 312. The first sorting conveyor line 316 is located between the first disc sorter 313 and the second sorting section 33. The first edge-adjusting machine 314 is located between the first disc sorter 313 and the first rotating roller machine 315. The rotating roller machine provides an access passage for the staff inside.

[0045] In this embodiment, the first single-piece separation conveyor 311, the first centering conveyor 312, the first disc sorter 313, the first edge-adjusting machine 314, the first flipping roller machine 315, the first sorting conveyor line 316, and the six-sided scanning equipment are existing technologies and will not be described again here.

[0046] In practice, irregularly shaped packages on the main line 23 are fed into the first single-piece separation conveyor 311. The first single-piece separation conveyor 311 separates the stacked irregularly shaped packages, ensuring that the packages leave as individual items. The separated packages then enter the first centering conveyor 312, which individually centers and feeds them onto the first disc sorter 313. Simultaneously, a six-sided scanning device scans the barcodes of the irregularly shaped packages on the first centering conveyor to obtain their information, allowing the first disc sorter 313 to... The irregularly shaped packages are sorted according to their information. If the irregularly shaped package is from the island, the first disc sorter sends the irregularly shaped package to the first sorting conveyor line 316, and sends the irregularly shaped package from the island to the second sorting section for secondary sorting. If the irregularly shaped package is from another island, the first disc sorter sends the irregularly shaped package to the first edge-adjusting machine 314, so that the first edge-adjusting machine 314 sends the irregularly shaped package from another island to the first tilting roller machine 315, and then the first tilting roller machine 315 sends the irregularly shaped package from another island to the multi-island conveying and sorting section 32 for sorting.

[0047] Combination Figure 5 , Figure 6 As shown, the multi-island conveyor sorting section 32 includes a first lifting conveyor 321, an input multi-layer conveyor 322, an elevator 323, an output multi-layer conveyor 324, and a second lifting conveyor 325. The first lifting conveyor 321 is vertically and vertically disposed between the first tilting roller machine 315 and the input multi-layer conveyor 322. The elevator 323 is disposed between the input multi-layer conveyor 322 and the output multi-layer conveyor 324. An intelligent sorting system is disposed above the multi-island conveyor sorting section. The elevator 323 is disposed between the input multi-layer conveyor 322 and the output multi-layer conveyor 324. An intelligent sorting system 326 is disposed above the multi-island conveyor sorting section. The second lifting conveyor 325 is vertically and vertically disposed between the output multi-layer conveyor 324 and the second sorting section 33.

[0048] In this embodiment, the input multi-layer conveyor 322 and the output multi-layer conveyor 324 are composed of several conveyors stacked along the height direction, so that the input multi-layer conveyor 322 and the output multi-layer conveyor 324 can hold multiple irregularly shaped packages, while the first and second lifting conveyors 321 and 325 are driven to lift by scissor lifts.

[0049] In specific operation, after the first rotating roller conveyor feeds the package onto the first lifting conveyor 321, the package rises to a level in the input multi-layer conveyor 322 where there are no packages. The first lifting conveyor then feeds the irregularly shaped package onto the corresponding input multi-layer conveyor 322. The input multi-layer conveyor 322 then feeds the irregularly shaped package onto the lifting conveyor 323. The lifting conveyor 323 rises to feed the irregularly shaped package into the intelligent sorting system for sorting. At the same time, it feeds the sorted irregularly shaped packages from other islands onto the lifting conveyor 323. Subsequently, the lifting conveyor 323 descends to a level in the output multi-layer conveyor 324 where there are no packages and feeds the irregularly shaped package onto the output multi-layer conveyor 324. Meanwhile, the second lifting conveyor 325 rises to a designated position on the output multi-layer conveyor 324 to receive the irregularly shaped packages output from the output multi-layer conveyor 324. This allows the second lifting conveyor 325 to feed the irregularly shaped packages from other islands into the second sorting section 33 for secondary sorting.

[0050] Combined Figure 7 As shown, the second sorting section 33 includes a second tilting roller machine 331, a first belt conveyor line 332, a second sorting conveyor line 333, a second single-piece separation conveyor 334, and a second central conveyor 335. The second sorting conveyor line 333 is connected to the first sorting conveyor line 316 at its beginning. The second single-piece separation conveyor 334 is located at the end of the second sorting conveyor line 333. The second central conveyor 335 is located between the second single-piece separation conveyor 334 and the multiple sorting section 34. The first belt conveyor line 332 is vertically arranged on one side of the second sorting conveyor line 333. The second tilting roller machine 331 is located between the first belt conveyor line 332 and the second lifting conveyor 325.

[0051] In practice, after being sorted in the first sorting section, parcels from the island are sent to the second sorting conveyor line 333 via the first sorting conveyor line 316. The second sorting conveyor line 333 then sends the irregularly shaped parcels from the island to the second single-piece separation conveyor 334, which performs a second single-piece separation of the irregularly shaped parcels, ensuring that the irregularly shaped parcels leave in a single piece state. The separated irregularly shaped parcels are then sent to the second centering conveyor 335, which then centers each of the irregularly shaped parcels sent from the second single-piece separation conveyor and sends them one by one to the multi-sorting section for final sorting.

[0052] In addition, packages from other islands are sorted by the multi-island conveyor sorting section 32 and then sent to the second tilting roller machine 331 by the second lifting conveyor 325. When the packages from other islands on the second tilting roller machine 331 are sent to the second sorting conveyor line 333 by the first belt conveyor line 332, the packages are also separated into individual pieces by the second single-piece separation conveyor 334, and then the second centering conveyor 335 sends the individual packages one by one to the multi-sorting section 34.

[0053] In this embodiment, the aforementioned intelligent sorting system is used to transport packages from multiple sorting lines to designated sorting lines. For example, if packages from other islands need to be transported to this island for sorting, the intelligent sorting system transports the packages to the designated multi-island conveying sorting section, which then sends the packages from other islands to multiple sorting sections for sorting. Alternatively, if packages from this island need to be transported to other islands for sorting, the packages are sent to the multi-island conveying sorting section through the first sorting section, which then sends the packages to the intelligent sorting system, which then transports the packages to the designated multi-island conveying sorting section. This embodiment improves multi-island sorting efficiency by using a multi-island joint sorting method to sort packages from other islands through a tray-based intelligent sorting system.

[0054] The multi-stage sorting section 34 includes a second disc sorter 341, a second belt conveyor 342, a box-packing waiting conveyor 343, a queuing waiting line 344, a return sorting line 345, a return roller machine 346, and a parcel collection section 347. The second disc sorter 341 is located between the second central conveyor 335 and the parcel collection section 347. The second belt conveyor 342 is located on one side of the second disc sorter 341. The box-packing waiting conveyor 343 is located between the second belt conveyor 342 and the box-packing table 13. The queuing waiting line 344 and the return sorting line 345 are respectively vertically located on one side of the second belt conveyor 342. The return roller machine 346 is located at the end of the return sorting line 345.

[0055] In practice, after the irregularly shaped packages from the island are sent into the multiple sorting section 34, they are sent to the corresponding second belt conveyor 342 by the second disc sorter. This allows the irregularly shaped packages on the second sorting conveyor to be diverted and processed. The second belt conveyor 342 then sends the irregularly shaped packages one by one to the boxing waiting conveyor 343, where workers pack the packages on the boxing waiting conveyor 343.

[0056] When an irregularly shaped package fails to be sorted or becomes abnormal after being sorted twice in the second sorting section, the high-speed diverter on the second belt conveyor 342 sends the failed or abnormal package to the return sorting line 345 for re-sorting.

[0057] Alternatively, if the parcels on the packing waiting conveyor line 343 cannot be processed in time, the high-speed diverter on the second belt conveyor line 342 will send the corresponding parcels to the queuing waiting line 344, so that the parcels on the queuing waiting line 344 can queue up and enter the module belt sorting section 35 for manual sorting, thereby avoiding sorting errors.

[0058] After the packages from other islands are sent to the second disc sorter 341, the second disc sorter 341 sends the package to the package collection section 347, so that the package collection section 347 collects the packages from other islands, thus facilitating the sorting of the packages from other islands.

[0059] Reference Figure 8 , Figure 9 As shown, the modular belt sorting section 35 includes several modular belt sorters 351, several boxing conveyors 352, and a package recycling conveyor 353. The modular belt sorters 351 are connected end-to-end and located at the end of the return sorting line 345. The boxing conveyors 352 are respectively vertically arranged on one side of each modular belt sorter 351. The package recycling conveyor 353 is located at the end of each modular belt sorter 351. Each modular belt sorter 351 includes a double-layer modular belt 3511 and a lifting mechanism 3512. In this embodiment, the modular belt sorter 351 can be adjusted according to... According to the sorting failure or abnormal package, the double-layer module belt moves the package towards the package recycling conveyor line 353, so that the package recycling conveyor line 353 can collect the package that failed to be sorted or cannot be sorted, thereby avoiding package sorting errors. Alternatively, the module belt sorter 351 can send the irregularly shaped package that cannot be processed in time by the subsequent sorting through the lifting mechanism 3512, so that the double-layer module belt 3511 can send the irregularly shaped package to the designated packing conveyor line 352, so that the packing conveyor line 352 can send the irregularly shaped package to the packing table 13 for manual packing.

[0060] Reference Figure 9 , Figure 10 As shown, specifically, the double-layer modular belt 3511 includes an upper inclined ball conveyor belt 35111, a lower ball conveyor belt 35112, and a fixed frame 35113. The upper inclined ball conveyor belt 35111 and the lower ball conveyor belt 35112 are tensioned on the fixed frame 35113. The balls of the lower ball conveyor belt 35112 are in contact with the inclined balls of the upper inclined ball conveyor belt 35111. The upper inclined ball conveyor belt 35111 and the lower ball conveyor belt 35112 are conveyed synchronously so that the irregularly shaped package moves towards the package recycling conveyor line 353 under the conveying of the double-layer modular belt 3511.

[0061] The lifting mechanism 3512 includes a non-powered roller conveyor 35121 and a base 35122. The base 35122 is fixedly installed inside the fixed frame 35113. The non-powered roller conveyor 35121 is vertically and flexibly installed above the base 35122. A lifting drive device is fixedly installed on the base 35122. In this embodiment, the lifting drive device is preferably a cylinder. When the irregularly shaped package on the double-layer module belt 3511 needs to be packed, the lifting drive device drives the non-powered roller conveyor to rise until the non-powered roller conveyor contacts the balls of the lower ball conveyor belt 35112, so that the upper inclined ball conveyor belt 35111 and the lower ball conveyor belt... When the conveyor belt 35112 moves forward, the balls of the lower ball conveyor belt 35112 drive the inclined balls of the upper inclined ball conveyor belt 35111 to rotate under the friction of the unpowered roller conveyor 35121. The angle between the inclined balls of the upper inclined ball conveyor belt 35111 and the conveying direction of the double-layer module belt 3511 is 30-60°. In this embodiment, 45° is preferred so that the inclined balls of the upper inclined ball conveyor belt 35111 can send the package into the packing conveyor line 352 in the specified direction. This can be used to divert packages that cannot be processed in time in the later stage of sorting, or to return packages that have failed or are abnormal, thereby avoiding sorting errors.

[0062] Reference Figure 8 As shown, to prevent irregularly shaped packages on the packing conveyor line 352 from falling onto the aisle 14, this embodiment is equipped with a foot-operated conveyor button on the packing conveyor line 352. This button is used to start or stop the packing conveyor line 352. When the irregularly shaped package on the packing conveyor line 352 moves to the end, the worker stops the packing conveyor line 352 by stepping on the foot-operated conveyor button. The worker then moves the irregularly shaped package at the end of the packing conveyor line 352 onto the packing table 13. After releasing the foot-operated conveyor button, the packing conveyor line is started again to continue conveying the irregularly shaped package, thereby assisting in manual packing.

[0063] Reference Figures 1-11 As shown, the present invention also provides a sorting method for an aviation irregularly shaped package sorting system, comprising the following steps:

[0064] S100: Several universal wheels transfer the flight container to the unpacking platform, where staff remove the irregularly shaped packages from the flight container and send them to the irregularly shaped package conveying unit.

[0065] S101, Several conveyor lines of the irregular package conveying unit will merge the irregular packages on the corresponding unpacking platform into the main line, so that the main line will send the irregular packages one by one into the first sorting section.

[0066] S102. The first single-piece separation conveyor separates the stacked irregular packages on the main line, and the separated irregular packages are sent one by one to the first disc sorter by the first centering conveyor. The first disc sorter sends the packages to the second sorting or multi-island conveyor sorting section according to the information of the irregular packages.

[0067] S103. The second sorting conveyor line sends the irregularly shaped packages on the first sorting section into the second single-piece separation conveyor for further separation, and then sends the irregularly shaped packages sent out from the second single-piece separation machine into the multiple sorting section through the second centering conveyor.

[0068] S104. The second disc sorter on the multiple sorting section sends the irregularly shaped packages into the second belt conveyor line, which then sends the irregularly shaped packages one by one into the packing waiting conveyor line. The staff then pack the packages on the packing waiting line into the flight cases on the packing table.

[0069] S105. Packages that fail to be sorted or are abnormal on the second belt conveyor line are sent to the return sorting line for return and sorted manually.

[0070] S106. When the sorting of irregularly shaped packages on the second belt conveyor cannot be processed in time, the second belt conveyor will send the corresponding irregularly shaped packages into the queuing line, so that the queuing line will send the packages into the module belt sorting section.

[0071] S107. Irregularly shaped packages that cannot be processed in time are sent to the packing conveyor line by the modular belt sorter, so that the packing conveyor line sends the irregularly shaped packages to the packing table for packing. Packages that fail to be sorted or are abnormal are sent to the package recycling line for return through the modular belt sorter.

[0072] In S102, the present invention identifies information about irregularly shaped packages using a six-sided scanning device. If the irregularly shaped package is from the same island, it is directly sent to the second sorting section for sorting. If the irregularly shaped package is from another island, it is sent to the multi-island conveying sorting section by the first disc sorter. The multi-island conveying sorting section then sends the irregularly shaped package to the intelligent sorting system for sorting. Packages from other islands in the intelligent sorting system need to be sorted on the same island, so the multi-island conveying sorting section sends the irregularly shaped package to the second sorting section for sorting.
