[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 6 The intelligent express delivery storage and retrieval system for universities includes: a main conveyor belt 4, on which an inlet scanner 1 for scanning express packages is installed, the inlet scanner 1 being positioned near the inlet of the main conveyor belt 4; a shelf 5 is located above the main conveyor belt 4, with the main conveyor belt 4 passing underneath the shelf 5; a robotic arm 6 for retrieving express packages is installed at one end of the shelf 5, and a storage belt 7 for temporarily storing express packages is installed on the shelf 5; multiple cursors 8 are rotatably connected to the side of the storage belt 7, and multiple micro motors for driving the cursors 8 are installed on the side of the storage belt 7; the shelf 5... An electric push rod 9 is provided on the side, and a drive mechanism for adjusting the position of the electric push rod 9 is installed on the shelf 5; the electric push rod 9 is arranged perpendicular to the length direction of the shelf 5, and a push plate is fixedly connected to the output end of the electric push rod 9; a branch conveyor belt 10 is connected to the shelf 5, and the branch conveyor belt 10 is located on one side of the shelf 5, with both ends of the branch conveyor belt 10 being close to both ends of the shelf 5; a shipping port scanner 11 is connected to the main conveyor belt 4, and the shipping port scanner 11 is located close to the shipping port of the main conveyor belt 4.

[0023] Note: When the device is in use, when the delivery vehicle arrives at the campus express station, all express packages are first poured into the system's inbound warehouse. All express packages will then enter the main conveyor belt 4 for conveying. When an express package passes the inbound scanner 1, the scanner 1 scans the tracking number. If the tracking number is facing up, the scan is successful, and the system provides a storage location (which container number, which floor, which position). The main conveyor belt 4 continues forward. When it reaches the storage container, the robotic arm 6 grabs the goods and moves them to the leftmost side of the corresponding floor. After the goods reach the leftmost side, the cursor 8 leaves the line, and the storage belt 7 of this floor begins to convey the goods to the right until the goods can no longer be moved, thus achieving the effect of aligning to the right and organizing the space.

[0024] It should also be noted that when a person scans the QR code at the pickup window to pick up the package, the system receives the pickup signal and provides the address of the corresponding goods. The vernier 8 at both ends of the goods (the vernier 8 of the goods and the vernier 8 of the adjacent goods) calculate the distance, and the electric push rod 9 at the bottom gently pushes the goods onto the branch conveyor belt 10 in front of the shelf 5. After sensing the gravity, the front branch conveyor belt 10 begins to move to the left until it reaches the far left. The robotic arm 6 takes out the goods and places them on the main conveyor belt 4. The goods pass through the main conveyor belt 4 and arrive at the pickup point.

[0025] It should also be noted that the outbound scanner 11 determines whether the current shipment and the previously scanned shipment belong to the same recipient. The outbound scanner 11 also has a signature function. When scanning the express code, it uses the front-facing camera to capture the recipient's face and updates the background information, thus playing a protective role in preventing disputes caused by misdelivery.

[0026] In summary, whenever goods enter the warehouse, a cursor 8 follows the goods into the warehouse. When goods leave the warehouse, the midpoint is calculated based on the addresses of the two cursors 8, and the goods are pushed onto the conveyor belt by an electric push rod 9 to complete the shipment. After shipment, the cursor 8 is retrieved by a micro motor. The remaining goods in the shelf 5 are compressed and their addresses are updated according to the algorithm. When inventory space is reclaimed, if the goods are scattered in different positions on the same layer of the shelf 5, the cursor 8 is moved directly to arrange all the goods in the area farthest from the exit of the shelf 5 for space reorganization, thereby improving the utilization rate of inventory space and saving storage and retrieval time.

[0027] refer to Figure 1 , Figure 3 and Figure 6 As shown, the drive mechanism includes a threaded rod 14. The shelf 5 is equipped with a threaded rod 14 that is parallel to its length direction. The shelf 5 is also equipped with a drive motor 15 for driving the threaded rod 14 to rotate, which is slidably connected to a mounting plate 13. The threaded rod 14 passes through the mounting plate 13 and is threadedly connected to the mounting plate 13. The electric push rod 9 is mounted on the mounting plate 13.

[0028] It should be noted that by driving the motor 15 to work, the threaded rod 14 is rotated, causing the mounting plate 13 to move along the threaded rod 14. This allows the mounting plate 13 and the electric push rod 9 to be adjusted so that the electric push rod 9 can move to the side of the goods (express delivery) that need to be pushed.

[0029] refer to Figure 1 and Figure 3 As shown, there are multiple storage bands 7, which are arranged in layers in the vertical direction.

[0030] Note: The multi-layer storage belt 7 enables layered storage of goods (express delivery), which is beneficial for the placement of goods and improves the utilization of space.

[0031] refer to Figure 1 As shown, a gate 2 is installed on the main conveyor belt 4, and a flipping component 3 for flipping express packages is also installed on the main conveyor belt 4.

[0032] It should be noted that: Gate 2 can be opened and closed. When Gate 2 is closed, the goods on the main conveyor belt 4 cannot pass through Gate 2, so the goods cannot enter the shelf 5. When Gate 2 is open, the goods on the main conveyor belt 4 can pass through Gate 2, so the goods can enter the shelf 5. The flipping component 3 can flip the goods so that the label side of the goods is facing up, that is, to ensure that the label on the goods can be recognized by the inlet scanner 1.

[0033] refer to Figure 1 and Figure 2 As shown, the flipping assembly 3 includes an arc-shaped flipping plate 31 and a hydraulic cylinder 32. The hydraulic cylinder 32 is installed on the main conveyor belt 4 and is inclined upward. The output end of the hydraulic cylinder 32 is fixedly connected to the arc-shaped flipping plate 31. The arc-shaped flipping plate 31 is set through the gap between two adjacent conveyor rollers in the main conveyor belt 4.

[0034] It should be noted that the hydraulic cylinder 32 can drive the arc-shaped flip plate 31 to move, so that the arc-shaped flip plate 31 slides out from the gap between two adjacent conveyor rollers in the main conveyor belt 4 and then contacts the goods on the main conveyor belt 4. The arc-shaped flip plate 31 flips the goods on the main conveyor belt 4, thereby adjusting the direction of the goods and ensuring that the labels on the goods can be recognized by the inlet scanner 1.

[0035] It should also be noted that if the inlet scanner 1 fails to scan the tracking number this time, the system will provide a flip scanning route and close checkpoint 2, allowing the package to go around once and enter the flip area. The flip component 3 will then flip the package over and allow it to re-enter the inlet scanner 1 until it succeeds.

[0036] refer to Figure 1 and Figure 5 As shown, the main conveyor belt 4 has multiple shipping conveyors installed at its outlet, and the outlet scanner 11 is installed on the shipping conveyor belt.

[0037] It should be noted that multiple shipping conveyors enable simultaneous multi-point shipping, improving shipping efficiency. Furthermore, multiple conveyors increase the shipping range and area, thus avoiding crowding at shipping points and improving the user experience.

[0038] refer to Figure 1 and Figure 5 As shown, the shipping conveyor belt is equipped with a baffle 12, which is positioned near the shipping port scanner 11.

[0039] Note: The outgoing port scanner 11 determines whether the current goods and the previously scanned goods belong to the same recipient. If they are not the same recipient, the baffle 12 is raised until the previous goods are taken by the recipient. Then the baffle 12 is opened again, and the recipient completes the pickup.

[0040] When in use, this invention incorporates the following movement algorithm for goods replacement and updates.

[0041] For a buffer zone consisting of n items (assuming the entire shelf has only 3 layers), the movement can be carried out in three steps, and the minimum number of moves required for each step is denoted as . :

[0042] (1) The minimum number of moves required to move n-1 items from the first floor to the second floor (using the third floor as a reference) is: ;

[0043] (2) Move the remaining goods on the first floor to the third floor. The minimum number of moves required is 1.

[0044] (3) The minimum number of moves required to move n-1 items from the 2nd floor to the 3rd floor (using the 1st floor as a reference) is: .

[0045] From the above steps, we can derive the formula for the minimum number of moves T(n) for n goods:

[0046]

[0047] Right now

[0048] make Therefore, we have:

[0049]

[0050] From the recurrence relation, we can obtain:

[0051] then

[0052] Therefore, based on the derivation above, we can conclude that the minimum number of steps required to build a shelf with n goods is... The next move will move all the goods to another layer of goods.

[0053] Through the three steps above, it is easy to see that this is a recursive process, but it is not the only method.

[0054] The same problem can be solved using a non-recursive approach. Non-recursion is not more complex than recursion. One iterative method is to divide the number of moves into odd and even moves. In odd moves, the smallest loop always moves in a fixed direction, such as clockwise (first layer → second layer → third layer → first layer) or counterclockwise (first layer → third layer → second layer → first layer). When the number of moves is even, only one move that conforms to the rule can be performed.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
