[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The basic implementation examples are as follows: Figure 1-2 The diagram illustrates an automated transfer control system for packaging carts 12. This system controls the operation of a transfer mechanism 1, which transfers packaging carts 12 onto or off the production line 7. The transfer control system includes a transfer control module 2 and a communication module 3. The transfer control module 2 connects to the transfer mechanism 1, AGV control module 5, WES system 4, and production line PLC 6 via the communication module 3, enabling data exchange. The production line PLC 6 controls the operation of the production line 7. The WES system 4 monitors the status of the cart doors in real time and sends the monitoring information to the transfer control module 2. The AGV control module 5 controls the AGV carts 8. The AGV carts 8 transport packaging carts 12 to the loading position or transport packaging carts 12 from the unloading position to the loading position.

[0020] Both the online and offline waiting positions include a trolley mechanism 14 and a guide rail 13. The trolley mechanism 14 is connected to the transfer control module 2 via a communication module 3. The guide rail 13 guides the transport path of the packing cart 12. The trolley mechanism 14 pushes the packing cart 12 in the online waiting position to the transfer waiting position and pushes the packing cart 12 in the offline waiting position to the transfer waiting position. A first detector 9 is provided at the transfer waiting position to detect whether a packing cart 12 is present and sends a detection signal to the transfer control module 2. A second detector 10 is provided in the online waiting position to detect whether a packing cart 12 is present and sends a detection signal to the transfer control module 2. A third detector 11 is provided at the transfer waiting position. The third detector 11 is used to detect whether there is a packing vehicle at the transfer waiting position and send the detection signal to the transfer control module 2. A fourth detector 15 is provided at the loading end of the off-line waiting position. The fourth detector 15 is used to detect whether there is a packing vehicle at the loading end of the off-line waiting position and send the detection signal to the transfer control module 2.

[0021] The transfer control module 2 sends control signals to the trolley mechanism 14 and the transfer mechanism 1, and sends a first notification signal to the AGV control module 5, based on the detection signals from the first detector 9, the second detector 10, the third detector 11, and the fourth detector 15. The AGV control module 5 controls the AGV trolley 8 according to the first notification signal. The transfer control module 2 sends a second notification signal to the line PLC 6 based on the operating status of the transfer mechanism 1. The line PLC 6 controls the opening and closing of the line 7 according to the second notification signal. A blocking mechanism is provided at the end of the line 7 to block the packing cart 12 at the end of the line 7. The blocking mechanism can be a blocking plate and a position sensor. The position sensor is connected to the transfer control module 2 and is installed on the blocking plate. The position sensor is used to detect whether the packing cart 12 is in position.

[0022] The online waiting area has m packing cart storage positions. A second detector 10 connected to the transfer control module 2 is located at the second-to-last packing cart storage position. The transfer waiting area is located at the end of the online waiting area (i.e., the last packing cart storage position). The push mechanism 14 of the online waiting area is located near the transfer waiting area. The push mechanism 14 is used to push the packing cart 12 in the second-to-last packing cart storage position towards the transfer waiting area. The transfer mechanism 14 is used to transfer the packing cart 12 from the transfer waiting area to the line body 7. The transfer control module 2 activates and deactivates the corresponding push mechanism 14 and sends a first notification signal to the AGV control module 5 to control the AGV trolley 8 based on the detection signal from the second detector 10.

[0023] The offline waiting area has n packing cart placement positions. A third detector 11, connected to the transfer control module 2, is located at the last packing cart placement position. The third detector 11 detects whether a packing cart 12 is present at the last placement position. A trolley pushing mechanism 14 is located at the initial end of the offline waiting area, and a transfer waiting area is located at the end of the offline waiting area, which is the last packing cart placement position. The trolley pushing mechanism 14 transports the packing cart 12 from the initial end to the second packing cart placement position. The transfer mechanism 14 transfers the packing cart 12 from the line 7 to the initial end of the offline waiting area. The transfer control module 2 activates and deactivates the corresponding trolley pushing mechanism 14 and sends a third notification signal to the AGV control module 5 to control the AGV trolley 8 based on the detection signal from the third detector 11.

[0024] The packaging cart 12 has a first connector and a second connector on its front and rear sides, respectively, and the first connector and the second connector can be connected. When the trolley mechanism 14 pushes the material, it will cause two adjacent packaging carts 12 to connect head-to-head. The first connector and the second connector can adopt the hook release device in CN223086889U.

[0025] The specific implementation process is as follows:

[0026] (I) Go-live operation:

[0027] The transfer control system first performs an initialization operation. After initialization, it checks whether the transfer mechanism 1 is in the initial state. If the transfer mechanism 1 is not in the initial state, it needs to return to the initial state; if the transfer mechanism 1 is in the initial state, the start operation can be performed.

[0028] The first detector 9 checks if there is a packing cart 12 at the transfer waiting position and sends a detection signal to the transfer control module 2. If a packing cart 12 is present, the transfer control module 2 sends a picking signal to the transfer mechanism 1, which then transfers the packing cart 12 from the waiting position. If there is no packing cart 12 at the waiting position, the second detector 10 checks if there is a packing cart 12 in the packing cart storage position. If there is, the transfer control module 2 activates the pusher mechanism 14 to push the packing cart 12 in the second-to-last storage position, and the subsequent packing carts 12 will follow suit. When the second detector 10 detects that there is no packing cart 12 in the storage position, the transfer control module 2 sends a notification signal to the AGV control module 5. The AGV control module 5 then controls the AGV trolley 8 to transport m packing carts 12 to the packing cart 12 storage position. After the transport is completed, the AGV trolley 8 departs.

[0029] WES system 4 controls the door gripper to reach the detection position. Sensors inside the door gripper detect the presence of a door and send the detection data to WES system 4. If a door is present, WES system 4 sends a door presence signal to transfer control module 2. Transfer control module 2 then controls transfer mechanism 1 to transfer the packing cart 12 and sends a second notification signal to line PLC 6, which stops line 7. After transfer mechanism 1 transfers the packing cart 12 onto line 7, it returns to the waiting position, and line 7 resumes operation.

[0030] (a) Logout Operation:

[0031] The transfer control system first performs an initialization operation. After initialization, it checks whether the transfer mechanism 1 is in the initial state. If the transfer mechanism 1 is not in the initial state, it needs to return to the initial state; if the transfer mechanism 1 is in the initial state, the start operation can be performed.

[0032] The blocking mechanism blocks and detects the packing cart 12. When the positioning sensor detects that the packing cart 12 has arrived, it sends a positioning signal to the transfer control module 2. The transfer control module 2 then activates the transfer mechanism 1 to transfer the packing cart 12. The fourth detector 15 checks if there is a cart at the first packing cart placement position. If there is no cart at the first placement position, the transfer mechanism 1 transfers the packing cart 12 to the first placement position and then returns to its original position. If there is a cart at the first placement position, the third detector 11 checks if there is a cart at the last placement position. If the third detector 11 detects no cart, the transfer control module 2 activates the pusher mechanism 14 to push the cart. If the third detector 11 detects a cart (indicating that there are carts at all n placement positions), the transfer control module 2 sends a third notification signal to the AGV control module 5. The AGV control module 5 sends a control signal to the AGV trolley 8, causing the AGV trolley 8 to reach the transfer waiting position and transfer the n packing carts 12.
