Description

Technical Field

[0001] This invention relates to a passenger baggage loading system and process for the front section of an aircraft cargo warehouse, and more particularly to a processing system and process for transporting passenger baggage from the baggage loading hall to the front section of the aircraft cargo warehouse in an airport baggage handling system, belonging to the field of logistics technology. Background Technology

[0002] In the existing airport baggage handling system, the conventional process for transporting passenger baggage from the terminal sorting hall to the aircraft cargo hold is as follows: staff manually load passenger baggage from the terminal sorting terminal equipment onto baggage carts, install netting or tarpaulins on top of the carts, and then the cart drivers drive the carts across the tarpaulin to the conveyor belt in front of the aircraft cargo hold. Staff then unload the baggage onto the conveyor belt, which transports the baggage inside the cargo hold for stacking. This process is incompatible with the requirements of modern smart airport construction and increases the labor intensity of staff handling passenger baggage. Summary of the Invention

[0003] (a) Technical problems to be solved The purpose of this invention is to address the shortcomings of the prior art by providing a passenger baggage loading system and process method at the front end of the aircraft cargo warehouse, thereby reducing the labor intensity of staff loading passenger baggage from the terminal sorting equipment to the conveyor belt process section in front of the aircraft cargo warehouse.

[0004] (II) Technical Solution To address the aforementioned technical problems, this invention provides a baggage loading system for departing passengers at the front end of an aircraft cargo hold. This system is used to transport hard-packed baggage and soft-packed baggage with baggage frames, sorted by the terminal baggage sorting equipment, to the aircraft cargo hold for loading. The baggage loading system includes a soft-packed baggage conveyor line, a hard-packed baggage conveyor line, an autonomous transfer forklift device, an autonomous transfer and transport device, a conveyor belt, and a scheduling system. Pallets are placed on both the soft-packed and hard-packed baggage conveyor lines. The soft-packed and hard-packed baggage conveyor lines are respectively located at the ends of the terminal baggage sorting equipment, and the conveyor belt is located at the aircraft cargo hold.

[0005] The hard-pack baggage conveyor line and soft-pack baggage conveyor line are used to receive and transport sorted hard-pack baggage and soft-pack baggage with baggage frames, respectively, and transfer the hard-pack baggage and soft-pack baggage in the baggage frames to pallets during the transport process. The autonomous transfer forklift device is used to transfer pallets and also to unload baggage from the pallets. The autonomous transfer and transport device centrally transports the pallets containing baggage to the conveyor belt. The conveyor belt transports the baggage to the aircraft cargo hold. The scheduling system is used to control the operation of the soft-pack baggage conveyor line, the hard-pack baggage conveyor line, the autonomous transfer forklift device, the autonomous transfer and transport device, and the conveyor belt. Through the above system architecture, unmanned and automated handling of passenger baggage is achieved from the terminal's sorting hall to the aircraft cargo hold.

[0006] Furthermore, the soft-pack luggage conveyor line includes a main conveyor line and an auxiliary conveyor line located on one side of the main conveyor line. A tilting device is installed in the middle section of the main conveyor line. The tilting device includes a support assembly, a conveying assembly, a telescopic assembly, and a clamping assembly. The conveying assembly is mounted on the support assembly, and one side of the conveying assembly is hinged to the support assembly. The telescopic assembly is located between the support assembly and the conveying assembly and can drive the conveying assembly to rotate along the hinge. The clamping assembly is mounted on the conveying assembly. The hard-pack luggage conveyor line includes a receiving conveyor line and a loading conveyor line located at its output end. Trays are placed on the auxiliary conveyor line of the soft-pack luggage conveyor line and the loading conveyor line of the hard-pack luggage conveyor line, respectively, for holding soft-pack luggage and hard-pack luggage.

[0007] Furthermore, the autonomous transfer forklift device includes a forklift body and a forklift mechanism mounted on the forklift body. The forklift mechanism includes a lifting assembly, an extension fork assembly, and a lifting assembly. The lifting assembly is mounted on the forklift body, the extension fork assembly is mounted on the lifting assembly, and one side of the extension fork assembly is hinged to the lifting assembly. The lifting assembly is located between the lifting assembly and the extension fork assembly and can drive the extension fork assembly to rotate along the hinge. The extension fork assembly is also provided with a retractable limiting assembly. The pallet is provided with fork holes for receiving the extension fork assembly. Through the above structure, the pallet can be forked and the luggage on it can be tilted. The autonomous transfer and transport device includes a transport vehicle body and a rack and a side sealing mechanism mounted on the transport vehicle body. The rack stores the pallet with luggage, and the side sealing mechanism covers the sides of the rack. On the other hand, the present invention also provides a method for loading departing passenger baggage at the front of an aircraft cargo warehouse, which employs the baggage loading system described above and is performed according to the following steps: S1. The hard baggage and soft baggage with baggage frames output from the terminal baggage sorting equipment are received through the hard baggage conveyor line and the soft baggage conveyor line, respectively. The hard baggage and soft baggage are loaded onto the pallets of the corresponding conveyor lines. Then the autonomous transfer forklift device transfers the pallets containing the baggage to the autonomous transfer transport device. After baggage loading is completed in S2 and S1, the autonomous transfer and transport device moves to the conveyor belt in front of the aircraft cargo hold. S3. The autonomous transfer forklift device removes the pallet containing the luggage from the autonomous transfer and transport device and transfers the luggage on the pallet to the conveyor belt. Then, the conveyor belt transports the luggage to the aircraft cargo hold.

[0008] Through the above processing procedures, passenger baggage can be transported automatically from the terminal's sorting hall to the aircraft cargo area.

[0009] More specifically, in S1, the process of loading the soft-pack luggage into the tray of the soft-pack luggage conveyor line is as follows: Step 001: The dispatching system dispatches the autonomous transfer forklift and autonomous transfer transport devices from their respective parking points to the soft baggage conveyor line; Step 002: The autonomous transfer and transport device opens the side sealing mechanism; Step 003: The autonomous transfer forklift device places the pallets stored on the autonomous transfer conveyor onto the auxiliary conveyor line to await loading; Step 004: Soft-pack luggage with luggage frames coming out of the end of the terminal baggage sorting equipment falls onto the main conveyor line and is transported to the tipping device; Step 005: The tipping device transfers the soft-pack luggage in the luggage frame to the tray on the auxiliary conveyor line.

[0010] Through the above processing steps, soft-pack luggage is automatically loaded into trays on the soft-pack luggage conveyor line.

[0011] More specifically, the operation process of the tilting device is as follows: a. Soft-pack luggage with luggage frames is transported to the tipping device, and the clamping components clamp the luggage frames; b. The telescopic component drives the conveyor component to rotate along the hinge, thereby causing the soft-pack luggage and luggage basket to rotate together, so that the soft-pack luggage automatically detaches from the luggage basket and enters the tray on the auxiliary conveyor line under the action of gravity and inertia. c. The telescopic component drives the conveying component to rotate in the opposite direction along the hinge to reset; d. The clamping assembly releases the luggage frame, which continues to be conveyed downwards out of the main conveyor line.

[0012] Through the above processing steps, soft-pack luggage is separated from luggage frames and the soft-pack luggage in the luggage frames is transferred to the trays on the auxiliary conveyor line.

[0013] More specifically, in S1, the process of loading the hard-pack luggage into the hard-pack luggage conveyor tray is as follows: Step 011: The dispatching system dispatches the autonomous transfer forklift and autonomous transfer transport devices from their respective parking points to the hard-pack luggage conveyor line; Step 012: The autonomous transfer and transport device opens the side sealing mechanism; Step 013: The autonomous transfer forklift device places the pallets stored on the autonomous transfer conveyor onto the loading conveyor line to await loading; Step 014: Hard-pack luggage exiting the terminal baggage sorting equipment falls onto the receiving conveyor line; Step 015: Hard-pack luggage is transported along the receiving conveyor and falls into a pallet on the loading conveyor.

[0014] Through the above processing steps, hard-pack luggage is automatically loaded into trays on the hard-pack luggage conveyor line.

[0015] More specifically, the process of the autonomous transfer forklift device transferring pallets is as follows: a. The lifting assembly drives the extension fork assembly to rise and fall to the height of the corresponding pallet. The forklift vehicle body drives the extension fork assembly to extend into the fork holes of the pallet. Then the lifting assembly drives the extension fork assembly to lift the pallet to complete the pallet lifting operation. b. After the autonomous transfer forklift device transports the pallet to the target position, the lifting component drives the extension fork component to lift the pallet above the placement surface of the target position. Then, the forklift vehicle moves the pallet above the placement surface. The lifting component drives the extension fork component to lower the pallet to the placement surface. The extension fork component continues to descend until it disengages from the inner surface of the pallet's fork hole. The forklift vehicle then drives the extension fork component out of the fork hole, completing the pallet placement operation.

[0016] Through the above processing steps, the autonomous transfer forklift device can automatically pick up and place transfer pallets.

[0017] More specifically, the operation process of S2 is as follows: Step 021: After the autonomous transfer and transportation device has completed loading the luggage, close the side sealing device; Step 022: After the baggage loading is completed, the autonomous transfer and transportation device runs to the working area of ​​the conveyor belt in front of the cargo hold of the corresponding flight according to the route planned by the scheduling system; Step 023: Wait for the autonomous transfer forklift to transfer the soft-pack and hard-pack luggage inside.

[0018] Through the above processing steps, the autonomous transfer and transportation device can autonomously transport luggage after it has been loaded.

[0019] More specifically, in S3, the process of the autonomous transfer forklift device transferring luggage from the pallet to the conveyor belt is as follows: Step 031: Open the side sealing device and use the autonomous transfer forklift to remove the pallet placed on the autonomous transfer conveyor. Step 032: The autonomous transfer forklift device moves with the pallet to the conveyor belt in front of the aircraft cargo hold; Step 033: The lifting assembly drives the extension fork assembly to rotate along the hinge, causing the pallet and the luggage on it to rotate. Under the action of its own weight and inertia, the luggage slides from the pallet onto the conveyor belt. Step 034: The lifting assembly drives the extension fork assembly to rotate in the opposite direction along the hinge to reset, and then unloads the next pallet.

[0020] The above processing steps enable the automatic transfer of luggage from the pallet to the conveyor belt.

[0021] (III) Beneficial Effects The above-described technical solution of the present invention has the following advantages: 1. Improve sorting efficiency and accuracy through automated, intelligent, and unmanned processing. Autonomous transfer forklifts and autonomous transport devices work in tandem to achieve continuous loading and unloading, avoiding the intermittent waiting times of traditional manual handling.

[0022] 2. Reduce labor costs and intensity: Automated loading, unloading, and conveying reduce direct human involvement, especially in high-frequency, heavy-duty operations, alleviating labor shortages. Human labor is only required for final stacking in the aircraft cargo hold, avoiding high-intensity handling throughout the entire process and reducing the risk of occupational injuries.

[0023] 3. To ensure the safety and integrity of luggage, the autonomous transfer forklift device, in conjunction with the pallet, can reduce damage caused by throwing.

[0024] 4. It possesses high flexibility and scalability, allowing for dynamic adjustment of equipment quantity based on flight volume to meet peak-hour demands.

[0025] 5. In line with the trend of smart airport construction, it improves passenger baggage transparency through automated node data collection, providing underlying support for the airport's digital transformation.

[0026] This invention, through classification and automated collaboration, has significant advantages in efficiency, safety, cost, and technological foresight, and represents an important practical direction for smart airport baggage handling systems.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1 like Figure 1-14As shown, an aircraft cargo hold front-end passenger baggage loading system is used to transport hard-pack baggage 7 and soft-pack baggage 1 with baggage frames (these are the two types of baggage sorted by conventional terminal baggage sorting equipment) to the aircraft cargo hold 14 for loading. The system includes a soft-pack baggage conveyor line, a hard-pack baggage conveyor line, an autonomous transfer forklift device 11, an autonomous transfer conveyor device 12, a belt conveyor 13, pallets 15, an industrial control computer (not shown in the figure, conventional existing technology can be used), and a scheduling system (not shown in the figure, conventional existing technology can be used). The soft-pack baggage conveyor line and the hard-pack baggage conveyor line are installed together on a support surface, usually located inside the terminal building. Multiple autonomous transfer forklift devices 11 and autonomous transfer conveyor devices 12 are usually prepared and centrally located in designated areas inside the terminal building or in designated non-open-air areas outside the terminal building. The conveyor belt 13 is located in a designated area on the apron and is scheduled by the terminal control system (or dispatch system) according to flight information. Its function is to transport passenger baggage from ground equipment to the aircraft cargo hold 14 (the aircraft cargo hold 14 is part of the aircraft and provides a storage point for passenger baggage during flight). The conveyor belt 13 can be equipped with an information receiving processor to receive, store, and verify the corresponding flight information, which can be achieved using existing technology.

[0046] The soft-pack luggage conveyor line includes a main conveyor line and an auxiliary conveyor line located on one side of the main conveyor line. The main conveyor line includes a sorting end soft-pack luggage end conveyor 3, a tilting device 4, and a downstream conveyor line 6 for empty soft-pack luggage baskets connected in sequence. The auxiliary conveyor line includes a soft-pack luggage tray platform conveyor 5. The hard-pack luggage conveyor line includes a receiving conveyor line and a loading conveyor line located at its output end. The receiving conveyor line includes a sorting end hard-pack luggage end conveyor 8 and a hard-pack luggage loading conveyor 9 connected in sequence. The loading conveyor line includes a hard-pack luggage tray platform conveyor 10.

[0047] Passenger baggage typically includes soft-pack baggage and hard-pack baggage. Soft-pack baggage is usually handbags, backpacks, and other passenger baggage with a soft outer surface. When passengers check in this type of baggage, it is placed in baggage basket 2 and then sorted and transported at the front of the baggage cart in the terminal.

[0048] The soft-pack baggage end conveyor 3 and the hard-pack baggage end conveyor 8 at the end of the baggage sorting system are conventional belt conveyors 13 of the terminal baggage sorting system equipment, which realize the transportation and stopping of baggage baskets 2 containing soft-pack baggage and hard-pack baggage.

[0049] The tilting device 4 includes a conveying device 41, a fixing device 42 (i.e., a clamping assembly), a tilting device 43, a detection device, and an information transmission device (these two are not shown in the figure and can be based on existing technology). It is used to convey and stop soft-pack luggage and luggage baskets 2, and to cause the soft-pack luggage and luggage baskets 2 to tilt together at a certain angle α, so that the soft-pack luggage automatically detaches from the soft-pack luggage basket 2 under the action of gravity and inertia, realizing the separation of the soft-pack luggage from the luggage basket 2, and simultaneously loading the soft-pack luggage onto a pallet. The conveying device 41 can be a conventional roller conveyor, belt conveyor, etc., and can be controlled by a control system to realize the transportation and stopping of soft-pack luggage, etc. It includes a support assembly 412 and a conveying assembly 411. One end of the conveying assembly 411 is connected to the support assembly 412 by a hinge. The support assembly 412 is installed on a support surface (generally the ground surface). The fixing device 42 is installed on the conveying device 41 and can be a conventional linkage clamping mechanism or a vacuum suction cup mechanism, etc., and the specific structural form is not limited. It can be controlled by the control system to achieve the function of fixing and separating the luggage basket 2 from the conveying device 41. In this embodiment, the linkage mechanism is used as an example for description, including a power device 421 (power source), a linkage device 422, a fixing plate 423, and a detection device (not shown in the figure, conventional existing technology is sufficient, such as proximity switch, RFID or laser identification technology, etc.); more specifically, it can be a lead screw assembly, a gear rack combination, or a telescopic rod, etc., and the clamping or releasing of the luggage basket is achieved by controlling the movement of the fixing plate 423. The flipping device 43 is a conventional flipping mechanism. In this embodiment, it is described as an electric cylinder (or hydraulic rod, i.e., telescopic component 432). It includes an electric cylinder, a hinge 431, and a detection device (not shown in the figure, conventional existing technology is sufficient). It is installed between the conveying component 411 and the support component 412 to provide power for the conveying component 411 to flip along the hinge point at a predetermined angle α, thereby driving the soft bag luggage and the luggage basket 2 to flip together. Under the action of gravity and inertia, the soft bag luggage automatically detaches from the luggage basket 2 and is loaded onto the tray located on the auxiliary conveyor line.

[0050] The soft-pack luggage pallet platform conveyor 5 and the hard-pack luggage pallet platform conveyor 10 can be conventional roller conveyors or belt conveyors, and the transportation and stopping of the pallets can be controlled by a control system. They can also be connected to an upstream pallet conveyor line (not shown in the figure, optional) to achieve pallet transportation docking. The soft-pack luggage pallet platform conveyor 5 is installed next to the tilting device 4 for pallet storage and transportation, enabling the pallets to receive and transport soft-pack luggage (side barriers or other structures can be installed to overcome the inertia or impact of falling luggage, preventing luggage from being thrown out of the soft-pack luggage pallet platform conveyor 5); the hard-pack luggage pallet platform conveyor 10 is installed below the hard-pack luggage loading conveyor 9 for pallet storage and transportation, enabling the pallets to receive and transport hard-pack luggage transported by the hard-pack luggage loading conveyor 9.

[0051] The hard-pack luggage loading conveyor 9 can be a conventional roller conveyor or belt conveyor, which can be controlled by a control system to transport and stop the hard-pack luggage, and is used to transport the hard-pack luggage to the pallet located on the hard-pack luggage pallet platform conveyor 10. The downstream conveyor line 6 for empty soft-pack luggage baskets can be a conventional roller conveyor or belt conveyor, which can be controlled by a control system to transport the luggage baskets 2 after unloading the soft-pack luggage downstream for subsequent processing. The pallet is a conventional cargo pallet, with fork holes 151 on the side for the autonomous transfer forklift device 11 to pick up, and an anti-slip limiting groove 152 structure on the bottom that can contact the shelf 122 to prevent relative movement between the pallet and the shelf 122. It should be noted that this function is not a mandatory configuration item.

[0052] Example 2 This embodiment is a further optimization of the autonomous transfer forklift device 11 and the autonomous transfer transport device 12 based on Embodiment 1. The autonomous transfer forklift device 11 includes a forklift body 111, a forklift mechanism 112, a detection device (not shown in the figure, existing technology can be used, its specific detection function can meet the requirements of the subsequent method use process, and the same applies to other detection mechanisms not shown), an internal controller, and an information transmission device (not shown in the figure, existing technology can be used). It realizes the forklifting and storage of pallets, and can tilt the forked pallet at a certain angle β, so that the passenger baggage on the pallet can be automatically detached from the pallet under the action of gravity and inertia, and unloaded onto the front conveyor belt 13 of the aircraft cargo hold 14. The forklift vehicle body 111 can be a conventional AGV, AMR, etc., and its drive device and running wheels can be controlled by the control system to run to the corresponding position according to the set trajectory. The forklift mechanism 112 is installed on the forklift vehicle body 111, and includes a lifting assembly 1121, an extension fork assembly 1122, a limiting assembly 1123 and a lifting assembly 1124. The lifting assembly 1121 is a conventional hydraulic lifting or chain lifting structure, and the specific form is not limited. Under the action of its power device and control system, it can realize vertical movement and stopping. The fork extension assembly 1122 is a conventional steel fork structure hinged to the lifting assembly 1121, providing support for the pallet being forked. It can tilt at a certain angle β along the hinge point under the action of the lifting assembly 1124. The limiting assembly 1123 is a conventional linear telescopic mechanism, which, under the action of its power device and control system, can achieve axial telescopic movement, thereby achieving contact and separation with the inner surface of the pallet fork hole 151. When it contacts the inner surface of the pallet fork hole 151, it achieves the lateral limiting function between the fork extension assembly 1122 and the pallet. The lifting assembly 1124 is installed between the lifting assembly 1121 and the fork extension assembly 1122. It can be a conventional linkage mechanism, electric cylinder mechanism, hydraulic cylinder mechanism, etc., and the specific structure is not limited. In this embodiment, an electric cylinder mechanism is used for description. Under the control of the control system, the electric cylinder extends, driving the fork extension assembly 1122 to tilt at a certain angle β along the hinge point.

[0053] The autonomous transfer and transport device 12 includes a transport vehicle body 121, a shelf 122 mounted on the transport vehicle body 121, and a side sealing mechanism 123. The shelf 122 stores a tray with luggage, and the side sealing mechanism 123 covers the sides of the shelf 122. The autonomous transfer and transportation device 12 includes a transport vehicle body 121, a shelf 122, a side sealing mechanism 123, a detection device (not shown in the figure, existing technology can be used), an internal controller, and an information transmission device (not shown in the figure, existing technology can be used). Under the control of a control system (or scheduling system), the autonomous transfer and transportation device 12 moves from one position to another along a predetermined trajectory and stops. The transport vehicle body 121 can be a conventional AGV, AMR, or other guided vehicle, and its drive unit and wheels can be controlled by the control system to move to the corresponding position along a set trajectory. The shelf 122 is installed on the transport vehicle body 121, providing storage support for pallets, and moves to the corresponding position along with the transport vehicle body 121. A rainproof layer can be installed on its exterior to protect the internal pallets and luggage. The side sealing mechanism 123 is installed on one opposite side of the shelf 122. It can be a conventional electric roller shutter door, and the specific structural form is not limited. The connection and isolation between the side of the shelf 122 and the outside world can be achieved through control of the control system or manual operation. In this embodiment, an electric roller shutter door is used as an example.

[0054] The autonomous transfer and conveying device 12 has two storage states: one is a fully loaded pallet stored at its storage point awaiting operation, and the other is an empty state without pallets stored at its storage point awaiting operation. When in the first state and operating at the sorting end conveyor station, the autonomous transfer forklift device 11 forks the pallets mounted on its internal shelf 122 and places them onto the corresponding pallet station conveyor. After the luggage is loaded onto the pallet, the autonomous transfer forklift device 11 forks the pallet loaded with luggage and places it back onto the shelf 122 of the autonomous transfer and conveying device 12. When in the second state and operating at the sorting end conveyor station, the pallets on the pallet station conveyor are supplied by the upstream pallet conveyor line. In this embodiment, the autonomous transfer and conveying device 12 is used in the storage state of a fully loaded pallet stored at its storage point awaiting operation.

[0055] It should be noted that, in this invention, the detection devices can be conventional photoelectric switches, proximity switches, limit switches, or other detection devices. Each autonomous transfer and transport device 12 carries passenger baggage from the same flight. Server-side software (such as a scheduling system) is deployed on a server in the baggage system's computer room. The server-side software provides services such as system management, retrieval, and external interfaces.

[0056] Example 3 This embodiment provides a method for using the loading system described in the above embodiment. The process flow is divided into three stages: loading soft-pack luggage into the autonomous transfer and transport device 12; loading hard-pack luggage into the autonomous transfer and transport device 12; transporting luggage from the autonomous transfer and transport device 12 to the front conveyor belt 13 of the aircraft cargo hold 14; and unloading luggage from the autonomous transfer and transport device 12 to the front conveyor belt 13 of the aircraft cargo hold 14. After passing through these stages, passenger luggage is transported by the front conveyor belt 13 of the aircraft cargo hold 14 to the aircraft cargo hold 14 for manual stacking. The implementation steps of each stage are as follows: 1. Steps for loading soft-pack luggage into the autonomous transfer and conveying device (process segment 12): Step 001: The control system (or scheduling system) controls the soft baggage of the corresponding flight to be sorted according to the flight information, and synchronizes the information of the assigned soft baggage end conveyor 3 station with the scheduling system; Step 002: The scheduling system dispatches the autonomous transfer forklift device 11 and the autonomous transfer and transport device 12 from their respective parking points to the corresponding sorting terminal soft baggage loading station for operation; Step 003: The autonomous transfer and conveying device 12 arrives at the soft baggage loading station at the end of the sorting process, opens the side sealing mechanism 123, and transmits the completion signal to the control system; Step 004: After the autonomous transfer forklift device 11 picks up the pallet stored on the shelf 122 inside the autonomous transfer and transport device 12, it is operated by the scheduling system and control system (the control system of the autonomous transfer forklift device 11 itself) to the work station next to the soft baggage pallet platform conveyor 5. The pallet is then placed on the soft baggage pallet platform conveyor 5 at position A (hereinafter referred to as soft baggage pallet platform conveyor 5A, and other words with letters have similar meanings) to wait for the soft baggage to be loaded.

[0057] 1) The pallet forklift operation process is as follows: a) With the cooperation of the control system (or scheduling system), detection device (not shown in the figure), internal controller and information transmission device (not shown in the figure), the autonomous transfer forklift device 11 follows its forklift vehicle 111 to the work area next to the autonomous transfer transport device 12. (b) The forklift mechanism 112 of the autonomous transfer forklift device 11 starts to operate. The lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 to rise and fall to the height of the corresponding pallet. After the detection device detects and verifies, the forklift vehicle 111 drives the extension component of the forklift mechanism 112 to match the relative position of the pallet fork hole 151. After the detection device detects and verifies, the forklift vehicle 111 drives the extension component 1122 of the forklift mechanism 112 into the pallet fork hole 151. After reaching the position, the lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 and the pallet to move upward a certain distance so that the pallet is separated from the contact surface of the internal rack 122 of the autonomous transfer transport device 12. After reaching the position, the forklift vehicle 111 drives the forklift mechanism 112 carrying the pallet to run outside the autonomous transfer transport device 12, completing the pallet forklift operation.

[0058] 2) The pallet placement process is as follows: a) The autonomous transfer forklift device 11 carrying the pallet, with the cooperation of the control system, detection device (not shown in the figure), internal controller and information transmission device (not shown in the figure), follows its forklift vehicle 111 to the work area next to the soft baggage pallet platform conveyor 5. b) The forklift mechanism 112 of the autonomous transfer forklift device 11 starts to work, and the lifting component 1121 of the forklift mechanism 112 drives the extension fork component 1122 to rise to a position higher than the conveying surface of the soft bag luggage pallet platform conveyor 5A. c) The forklift body 111 drives the forklift mechanism 112 and the pallet into the upper part of the soft-pack luggage pallet platform conveyor 5A; d) The lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 to descend to the height where the soft-pack luggage pallet platform conveyor 5A contacts the pallet. After that, it continues to descend a certain distance until the upper surface of the pallet fork hole 151 is separated from the extension component 1122. After the detection device detects and verifies, the forklift vehicle 111 drives the extension component 1122 to move outward so that the extension component 1122 is completely separated from the pallet fork hole 151 area, thus completing the pallet placement operation.

[0059] Step 005: The luggage basket 2 loaded with soft-pack luggage is transported to the tipping device 4 by the sorting end soft-pack luggage end conveyor 3; Step 006: The tipping device 4 begins the tipping operation of soft-pack luggage. The specific operation process is as follows: a) Under the control of its internal structure and control system, the fixing device 42 of the tilting device 4 causes its attached fixing plate 423 to move from the open (open) state to the closed (clamped) state, thereby achieving relative fixation between the luggage basket 2 and the conveying device 41 of the tilting device 4. b) The tilting device 43 of the tilting device 4 starts to operate. Under the cooperation of its power device 421, connecting rod device 422, fixed plate 423 and detection device, the power device electric cylinder extends to cause the conveying component 411 to tilt along the hinge point at a predetermined angle α, thereby driving the soft bag luggage and the luggage basket 2 to tilt together, so that the soft bag luggage automatically detaches from the luggage basket 2 under the action of gravity and inertia and is loaded onto the pallet located on the soft bag luggage pallet platform conveyor 5A. c) When the overturning device 43 of the tilting device 4 retracts its power device electric cylinder, it causes the conveying assembly 411 to flip along the hinge point at a predetermined angle α to its original state. d) Under the control of its internal structure and control system, the fixing device 42 of the tipping device 4 moves its attached fixing plate 423 from the closed state to the open state, thereby releasing the relative fixation between the luggage basket 2 and the conveying component 411 and completing the tipping operation of soft-pack luggage.

[0060] Step 007: The luggage basket 2 after unloading soft-pack luggage is transported by the conveying component 411 of the tipping device 4 to the downstream conveyor line 6 of the empty soft-pack luggage basket for subsequent related operations; Step 008: The pallet loaded with soft-pack luggage is completed under the control of the scheduling system and the control system. It can wait on the soft-pack luggage pallet platform conveyor 5A for the autonomous transfer forklift device 11 to pick it up, or it can be transported from the soft-pack luggage pallet platform conveyor 5A to the soft-pack luggage pallet platform conveyor 5B to wait for the autonomous transfer forklift device 11 to pick it up. Step 009: Under the control of the scheduling system and the control system, the autonomous transfer forklift device 11 runs to the work station next to the soft baggage pallet platform conveyor 5. The autonomous transfer forklift device 11 forks the pallets that have been completed and loaded onto the soft baggage pallet platform conveyor 5 and puts them back on the internal shelf 122 of the autonomous transfer and transport device 12 for storage. This process is the reverse of the operation process of step 004.

[0061] The above operation involves loading a single soft-pack baggage into the autonomous transfer and transport device 12. In practice, multiple sorting end soft-pack baggage end conveyors 3, tilting devices 4, soft-pack baggage pallet platform conveyors 5, sorting end hard-pack baggage end conveyors 8, autonomous transfer forklift devices 11, etc., can work together to complete the process of loading soft-pack baggage from the same flight into the autonomous transfer and transport device 12. Hard-pack baggage and soft-pack baggage from the same flight share the same autonomous transfer and transport device 12.

[0062] 2. Steps for loading hard-pack luggage into the autonomous transfer and conveying device (process segment 12): Step 011: The control system controls the sorting of hard-pack baggage for the corresponding flight based on the flight information, and synchronizes the information of the assigned sorting terminal hard-pack baggage loading platform with the dispatch system; Step 012: The scheduling system dispatches the autonomous transfer forklift device 11 and the autonomous transfer conveyor device 12 from their respective parking points to the corresponding sorting end hard-pack luggage loading station for operation; Step 013: The autonomous transfer and transport device 12 arrives at the sorting end hard-pack luggage end conveyor 8 station, opens the side sealing mechanism 123, and transmits the completion signal to the control system (or scheduling system). Step 014: After the autonomous transfer forklift device 11 picks up the pallet stored on the shelf 122 inside the autonomous transfer and transport device 12, it is operated by the scheduling system and control system to the work station next to the hard-pack luggage pallet platform conveyor 10 (hereinafter referred to as hard-pack luggage pallet platform conveyor 10C) at position C, and then the pallet is placed on the hard-pack luggage pallet platform conveyor 10C to wait for the loading of hard-pack luggage. 1) The pallet forklift operation process is as follows: a) With the cooperation of the control system (or scheduling system), detection device (not shown in the figure), internal controller and information transmission device (not shown in the figure), the autonomous transfer forklift device 11 follows its forklift vehicle 111 to the work area next to the autonomous transfer transport device 12. b) The forklift mechanism 112 of the autonomous transfer forklift device 11 starts to operate. The lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 to rise and fall to the height of the corresponding pallet. After the detection device detects and verifies, the forklift vehicle 111 moves the extension component 1122 of the forklift mechanism 112 to the relative position of the pallet fork hole 151. After the detection device detects and verifies, the forklift vehicle 111 moves the extension component 1122 of the forklift mechanism 112 into the pallet fork hole 151. After it is in place, the lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 and the pallet to move upward a certain distance so that the pallet is separated from the contact surface of the internal rack 122 of the autonomous transfer transport device 12. After it is in place, the forklift vehicle 111 drives the forklift mechanism 112 carrying the pallet to run outside the autonomous transfer transport device 12, completing the pallet forklift operation.

[0063] 2) The pallet placement process is as follows: a) The autonomous transfer forklift device 11 carrying the pallet, with the cooperation of the control system, detection device (not shown in the figure), internal controller and information transmission device (not shown in the figure), follows its forklift vehicle 111 to the work area next to the hard-pack luggage pallet platform conveyor 10. b) The forklift mechanism 112 of the autonomous transfer forklift device 11 starts to operate. The lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 to descend to the height where the hard-pack luggage pallet platform conveyor 10C contacts the pallet. After that, it continues to descend a certain distance until it disengages from the upper surface of the pallet fork hole 151. After the detection device detects and verifies, the forklift vehicle 111 drives the extension component 1122 to move outward so that the extension component 1122 completely disengages from the pallet fork hole 151 area, thus completing the pallet placement operation.

[0064] Step 015: Hard-pack luggage is transported from the sorting end hard-pack luggage end conveyor 8 to the hard-pack luggage loading conveyor 9, and then dropped onto the pallet transported by the lower hard-pack luggage pallet platform conveyor 10D. Step 016: The pallet is transported from the hard-pack luggage pallet platform conveyor 10C to the hard-pack luggage loading conveyor 9D, and the hard-pack luggage transported by the hard-pack luggage loading conveyor 9D above is dropped to complete the loading of hard-pack luggage onto the pallet; Step 016: The pallet loaded with hard-pack luggage is transported from the hard-pack luggage pallet platform conveyor 10D to the hard-pack luggage pallet platform conveyor 10E, waiting to be picked up by the autonomous transfer forklift device 11. Step 017: Under the control of the scheduling system and the control system, after the autonomous transfer forklift device 11 runs to the work station next to the hard-pack luggage loading platform, the autonomous transfer forklift device 11 picks up the hard-pack luggage pallet that has been loaded on the hard-pack luggage pallet platform conveyor 10E and puts it back on the internal shelf 122 of the autonomous transfer and transport device 12 for storage. This process is the reverse of the operation process of step 014.

[0065] The above describes the loading of a single hard-pack baggage into the autonomous transfer and transport device 12. In practice, multiple sorting end hard-pack baggage end conveyors 8, hard-pack baggage loading conveyors 9, hard-pack baggage pallet platform conveyors 10, autonomous transfer forklift devices 11, etc., can work together to complete the process of loading hard-pack baggage from the same flight into the autonomous transfer and transport device 12. Hard-pack baggage and soft-pack baggage from the same flight share the same autonomous transfer and transport device 12.

[0066] 3. Autonomous transfer and conveying device 12 transports baggage to the aircraft cargo hold 14. Front conveyor belt 13. Process steps of the workstation section: Step 021: After the internal shelf 122 of the single autonomous transfer and transport device 12 is filled with soft-pack and hard-pack luggage, the roller shutter door of the side sealing mechanism 123 is closed to protect the soft-pack and hard-pack luggage on the pallet of the shelf 122 during transportation. Step 022: Under the control of the scheduling system and control system, the autonomous transfer and transportation device 12, which is filled with luggage, runs according to the system's planned path to the working area of ​​the conveyor belt 13 in front of the aircraft cargo hold 14 of the corresponding flight aircraft in the designated area of ​​the apron. Step 023: After the internal controller and information transmission device (not shown in the figure) of the autonomous transfer and transport device 12 verify the flight information with the information receiving processor on the front belt conveyor 13 of the aircraft cargo hold 14, wait for the autonomous transfer forklift device 11 to perform forklift operations on the soft and hard baggage carried inside.

[0067] 4. Autonomous transfer and conveyor device 12 unloads baggage to aircraft cargo hold 14. Front conveyor belt 13 process steps: Step 031: The dispatching system dispatches the autonomous transfer forklift device 11 and the autonomous transfer conveyor device 12 from their respective parking points to the working area of ​​the conveyor belt 13 in front of the aircraft cargo hold 14 of the corresponding flight aircraft in the designated area of ​​the apron, and performs information docking and confirmation. Step 032: The autonomous transfer and conveying device 12 opens the roller shutter door of the side sealing mechanism 123, and the autonomous transfer forklift device 11 forks the pallet placed on the shelf 122. Step 033: After the autonomous transfer forklift device 11 picks up the pallets containing soft-pack and hard-pack luggage from the rack 122 inside the autonomous transfer and transport device 12, it moves them to the working area at the front conveyor belt 13 of the aircraft cargo hold 14 under the control of the scheduling system and the control system; the pallet picking operation process is consistent with the pallet picking operation process described in step 004 1).

[0068] Step 034: The autonomous transfer forklift device 11, through the internal structural action of its forklift mechanism 112, drives the pallet to flip, thereby causing the passenger baggage on the pallet to flip as well. After reaching the preset angle β, the passenger baggage slides off the pallet onto the front conveyor belt 13 of the aircraft cargo hold 14 under its own weight and inertia. Subsequently, the passenger baggage is transported by the front conveyor belt 13 of the aircraft cargo hold 14 to the aircraft cargo hold 14 for manual stacking.

[0069] The work process is as follows: a) The lifting component 1121 of the forklift mechanism 112 drives the extension component 1122 with the pallet to adjust up and down, so that the pallet moves to above the lower belt surface of the front conveyor 13 of the aircraft cargo hold 14, and this position meets the space requirements for subsequent tipping. b) The limiting component 1123 of the fork-taking mechanism 112 moves from the retracted state to the extended state, that is, the fork extension component 1122 contacts the inner cavity of the pallet fork hole 151, thereby realizing the relative limiting function between the fork extension component 1122 and the pallet laterally, but this process is not a necessary step. c) The flipping device (lifting assembly 1124) of the forklift mechanism 112, under the action of its electric cylinder extension, causes the fork extension assembly 1122 to flip along the hinge point at a certain angle β, thereby driving the pallet and the passenger baggage carried to flip together along the hinge point at a certain angle β. When the preset angle β is reached, the passenger baggage slides from the pallet onto the front conveyor belt 13 of the aircraft cargo hold 14 under the action of its own weight and inertia. d) The flipping device of the fork-taking mechanism 112, under the action of the retraction of its electric cylinder, causes the fork extension assembly 1122 to flip back to its original state along the hinge point; e) The limiting component 1123 of the fork-taking mechanism 112 moves from the extended state to the retracted state, that is, the fork extension component 1122 disengages from the inner cavity of the pallet fork hole 151, thereby canceling the relative lateral limiting between the fork extension component 1122 and the pallet. However, this process is not a necessary step and exists simultaneously with step b.

[0070] Step 035: The autonomous transfer forklift device 11 places the unloaded empty pallet back onto the shelf 122 of the autonomous transfer conveyor device 12. This step is the complete opposite of the operation process described in step 033. Step 036: After all the luggage on the inner shelf 122 of the autonomous transfer and conveying device 12 is unloaded and all the empty pallets are returned, under the control of the scheduling system and the control system, the autonomous transfer and conveying device 12 runs to the corresponding sorting end luggage loading station for operation, or runs to the storage area of ​​the autonomous transfer and conveying device 12 to wait for subsequent operations.
