The RFID electronic tags are used to mark the number information of the maintenance bracket 303 at the corresponding position. A reader is provided on the outer surface of 2025, and the reader can identify the number information stored in the RFID electronic tag and send it to the control device. The control device determines whether the maintenance bracket 303 corresponding to the number is in a load-bearing state. When the control device determines that the maintenance bracket 303 is not loaded, the control device controls the drive motor 2026 to stop rotating and controls the brake to brake. The control device controls the main cylinder 2035 and / or the auxiliary cylinder 2036 to drive the conveyor belt 203 to move until the pressure sensor 1 sends a corresponding electrical signal to the control device. The control device controls the corresponding conveying motor 2031 to rotate until the pressure sensor 2 sends a corresponding electrical signal to the control device, and the control device starts to time the maintenance time of the window frame.

[0044] Pressure sensor 2, pressure sensor 3 and pressure sensor 4 all send corresponding electrical signals to the control device only after the window frame is fully transported into place and senses the pressure generated by the window frame due to its entire dead weight; each motor in this specific embodiment includes a reducer to increase the torque and improve the transportation capacity; in order to prevent the braking distance of the transport vehicle 202 from being too long, the driving conveyor belt 203 and the driven conveyor belt 304 cannot be accurately docked, before being put into use, the position of the RFID electronic tag and the speed of the driving motor 2026 are tested and adjusted until it is ensured that after the transport vehicle 202 is parked, the driving conveyor belt 203 and the feeding conveyor belt 405 and the driven conveyor belt 304 can be docked to achieve accurate transportation of the window frame. At the same time, setting the bandwidth of the driving conveyor belt 203, the bandwidth of the feeding conveyor belt 405 and the bandwidth of the driven conveyor belt 304 to be the same can also facilitate accurate transportation of the window frame and avoid bumps.

[0045] This specific embodiment also provides a window frame storage method, which uses the above-mentioned intelligent window frame storage system and includes the following steps:

[0046] S01: After the loading device carries the window frame, the pressure sensor sends an electrical signal to the three-way control device, and the lifting cylinder extends to rotate the conveying bracket to a position where the angle with the horizontal direction is b. At the same time, the control device controls the transport vehicle to move to the loading end. After the driving conveyor belt is aligned with the feeding conveyor belt, the control device controls the feeding motor to drive the feeding conveyor belt to transport the window frame to the driving conveyor belt. When the control device receives the electrical signal sent by the pressure sensor four, it controls the lifting cylinder of the loading device to retract, and the conveying bracket returns to a horizontal state, and at the same time controls the driving motor to work;

[0047] S02: The control device controls the transport vehicle to move along the track until it finds a maintenance support in an empty state. During the movement of the transport vehicle, the reader continuously reads the RFID electronic tags on both sides and sends the number information to the control device until the control device determines that the maintenance support corresponding to the number is in an empty state. The control device controls the drive motor to stop and controls the brake to brake at the same time;

[0048] S03: When the corresponding maintenance bracket is identified to be in a non-load-bearing state, the control device controls the auxiliary cylinder and the main cylinder to extend or retract, driving the conveyor belt to move to one side, and the reversing gear on one side of the conveyor belt meshes with the corresponding driven gear. When the control device receives the electrical signal transmitted by the pressure sensor 1, the control device controls the auxiliary cylinder to stop moving and controls the conveying motor to work, driving the conveyor belt to convey the window frame to the driven conveyor belt. When the pressure sensor 2 sends a corresponding electrical signal to the control device, the control device controls the transport vehicle to return to the loading end, and repeats S01 to S03.

[0049] S04: When the pressure sensor 2 sends a corresponding electrical signal to the control device, the control device starts timing the stored window frame until the maintenance time is met;

[0050] S05: When the control device determines that the window frame on the maintenance bracket has reached the maintenance time, the control device controls the corresponding transport vehicle to move to the corresponding maintenance bracket. During the movement of the transport vehicle, the reader continuously reads the RFID electronic tags on both sides and sends the number information to the control device until the control device determines that the number corresponds to the maintenance bracket that needs to be unloaded. The drive conveyor belt moves toward the corresponding maintenance bracket under the action of the main cylinder and / or the auxiliary cylinder until the reversing gear is engaged with the driven gear, and the conveying motor drives the drive conveyor belt to transport the window frame to the drive conveyor belt. When the pressure sensor four-way control device sends an electrical signal, the control device controls the transport vehicle to return to the unloading end and changes the state corresponding to the maintenance bracket with this number to no-load;

[0051] S06: When the driving conveyor belt of the transport vehicle is aligned with the feeding conveyor belt, the control device controls the feeding conveyor belt on the conveying device to start conveying, and the control device controls the driving conveyor belt to convey the window frame to the feeding conveyor belt. When the control device receives the signal transmitted by the pressure sensor 2 on the conveying device, the conveying bracket rotates to a horizontal state, and the control device controls the roller conveyor to convey the window frame away. The conveying bracket rotates to a state where the angle with the horizontal direction is b, and steps S05 to S06 are repeated.

[0052] Among them, in S03, when the maintenance brackets on both sides of the transport vehicle are in a non-load-bearing state, the transport vehicle prioritizes storing the window frames on the right maintenance bracket, controls the main cylinder and the auxiliary cylinder to contract, and drives the conveyor belt to move to the right; in S05, when the transport vehicle receives both loading and unloading transport tasks at the same time, when the transport vehicle prioritizes the unloading transport task, it can ensure that the storage device is fully utilized, and the window frames that have reached the maintenance time are transported away in time, thereby improving the turnover efficiency of the system and the accuracy of controlling the maintenance time.

[0053] From the above specific implementations, it can be seen that the present invention has the following beneficial effects:

[0054] 1. Through the coordination of the feeding device, transportation device, storage device, conveying device and control cabinet, manual handling and timing are replaced, and the maintenance time is accurately controlled with high efficiency;

[0055] 2. The driving conveyor belt and the driven conveyor belt can be conveyed in the same direction through the cooperation of the driving gear, the reversing gear and the driven gear. It has high reliability and low failure rate, and can reliably complete the task of window frame storage;

[0056] 3. The driving conveyor belt can be docked at three positions through the cooperation of the main cylinder and the auxiliary cylinder, so that the transport vehicle can dock with the driven conveyor belts on both sides, thereby improving the working efficiency of the transport vehicle;

[0057] 4. By using I-beams, anti-tilt wheels and guide wheels, the moving direction of the transport vehicle can be ensured, deviation can be reduced, and tipping due to inertia can be prevented when the transport vehicle stops moving;

[0058] 5. The cooperation between the protective bracket and the supporting bracket can prevent the window frame from shaking and protect the window frame during transportation; by setting 70°<a<80°, the window frame can be tilted and leaned on the supporting bracket and the maintenance bracket to improve the stability of the window frame during transportation and storage, and prevent deformation during maintenance;

[0059] 6. Through the coordination of multiple pressure sensors, RFID technology and control devices, the accuracy and automation level of the system operation can be improved, and the efficiency and space utilization can be improved.
