The sliding rod slides in the opposite direction to drive the blocking rod to open the bottom of the material lifting frame; S8, the lifting drive motor drives the lifting frame to move upward. During the rising process, the material in the lifting frame loses the blocking effect of the blocking rod and is placed on the material conveying rack, completing the unloading process from the lifting frame to the material conveying rack. The lifting frame rises to the initial position of the lifting stroke and triggers the proximity switch at that position before stopping; S9, the material moving mechanism drives the material lifting frame to move to the material frame separation position, triggers the proximity switch at this position and stops, the material lifting drive motor drives the material lifting frame to move downward until the bottom of the material lifting frame contacts the top of the transport material frame, triggers the proximity switch at the end position of the lifting stroke of the material lifting frame and stops, and the locking device starts to lock the material lifting frame and the transport material frame; S10, the material lifting driving motor drives the material lifting frame to move upward, and at the same time drives the transport material frame to lift upward, the material lifting frame rises to the initial position of the lifting stroke and triggers the proximity switch at that position and stops, the material moving mechanism drives the material lifting frame and the transport material frame to return to the first material picking position and triggers the proximity switch at that position and stops; S11, the lifting drive motor drives the lifting frame to move downward, and when the bottom of the transport frame contacts the top of the material car, the proximity switch at the end position of the lifting frame lifting stroke is triggered and the lifting frame stops, the locking device is unlocked, and the lifting drive motor drives the lifting frame to move upward, completing the separation of the lifting frame and the transport frame, and stops after being lifted to the initial position of the lifting stroke of the lifting frame and triggering the proximity switch at that position, completing the unloading action of the first material picking position; S12, the material moving mechanism drives the material lifting frame to move to the second material taking position, triggers the proximity switch at the position and stops, and repeats S3-S11 to complete the unloading action at the second material taking position; S13, the mechanical limit device of the first stop position releases the restriction, the trolley continues to move forward to the second stop position and triggers the mechanical limit device at the position and then stops, and the trolley adjustment mechanism adjusts the stop position of the trolley; S14, repeat S2-S12, complete the unloading action of the transport material frame in the rear half of the material cart, the mechanical limit device of the second stop position releases the restriction on the material cart to continue to move forward and leave, and completes the unloading action of all the transport material frames on the material cart.
