2) when the control device predicts that the sorting trolley 1 moves to the target outlet of the package, namely the control device predicts that the order information of the package on the tray 12 is the same as the position information of the next outlet, the control device controls the driving end of the driving piece 62 in the unloading mechanism 6 to descend so that the package dropping roller 63 and the supporting piece 131 of the locking mechanism 13 on the sorting trolley 1 are positioned at the same height;

3) when the sorting trolley 1 moves to a target outlet, the package falling roller 63 of the unloading mechanism 6 is abutted against the supporting piece 131 of the locking mechanism 13, the sorting trolley 1 continues to move, the supporting piece 131 rotates under the action of the package falling roller 63, the other end of the supporting piece 131 releases the tray 12, and the tray 12 rotates downwards to drop materials under the action of gravity;

4) the sorting trolley 1 continues to move to the reset track 4, the curled edge 122 on the tray 12 abuts against the upper surface of the reset track 4, under the action of the ascending section 41 of the reset track 4, the tray 12 rotates upwards to reset and pushes away the supporting roller 133 through the inclined push block 121, so that the supporting piece 131 rotates until the sorting trolley 1 moves to the horizontal section 42 of the reset track 4, the tray 12 returns to a material bearing state, and at the moment, the supporting piece 131 returns to an initial position under the action of the reset elastic piece 132 to support the tray 12. This completes a sort cycle.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
