[0063] A coil spring is arranged between the rotating disc 204d and the supporting disc 204c, which is used for resetting the rotating disc 204d, and the coil spring is a prior art and will not be described here. The end of the pulling rope 204h is fixed in the wire disc 204f, the end of the driving arm 204e is connected with the sliding rod 204a through a rotating shaft, the rotating shaft at the end of the driving arm 204e is slid in the sliding groove of the sliding rod 204a. When the pulling rope 204h is pulled, the wire disc 204f is driven to rotate, so that the wire disc 204f drives the rotating disc 204d to rotate, the rotating disc 204d drives the driving arm 204e to swing, so that the driving arm 204e is slid in the sliding groove of the sliding rod 204a through the rotating shaft, thereby driving the sliding rod 204a to move, so that the sliding rod 204a drives the pushing block 204b to move, and the pushing block 204b pushes the logistics box 104 on the top of the lifting plate 201f away.

[0064] Specifically, the unloading piece 204 further comprises a positioning block 204i, a direction-changing column 204j, a sliding frame 204k, a clamping block 204l, a fourth spring 204m and a reset plug 204n, the positioning block 204i is fixed on the bottom of the lifting plate 201f, the direction-changing column 204j is fixed on the bottom of the lifting plate 201f, the sliding frame 204k is slid on the surface of the lifting plate 201f, the clamping block 204l is slid in the sliding frame 204k, the fourth spring 204m has two ends respectively fixed on one side of the sliding frame 204k and one side of the clamping block 204l, and the reset plug 204n is fixed on one side of the lifting plate 201f.

[0065] The limit block is arranged on one side of the sliding frame 204k and is fixed to the surface of the lifting plate 201f. The end of the cable 204h is fixed to one side of the sliding frame 204k. The number of the positioning blocks 204i is more than one, which are used for supporting and positioning the cable 204h. The direction-changing column 204j is used for supporting the cable 204h, so that the cable 204h can change direction. When the moving frame 202d moves, the second shifting rod 202h can drive the clamping block 204l, so that the clamping block 204l drives the sliding frame 204k to move, and the sliding frame 204k drives the cable 204h on one side to move. When the cable 204h is pulled, the wire reel 204f can be driven to rotate, so that the wire reel 204f drives the rotating disc 204d to rotate. The rotating disc 204d can drive the driving arm 204e to swing, so that the driving arm 204e slides in the sliding groove of the sliding rod 204a through the rotating shaft, thereby driving the sliding rod 204a to move, so that the sliding rod 204a drives the shifting block 204b to move, and the shifting block 204b pushes away the logistics box 104 on the top of the lifting plate 201f. With the movement of the sliding frame 204k, the sliding frame 204k approaches the reset plug block 204n, so that the reset plug block 204n is inserted on one side of the clamping block 204l. One side of the clamping block 204l is provided with an inclined slot. When the reset plug block 204n is inserted into the inclined slot, the clamping block 204l is retracted into the moving frame 202d. At this time, the second shifting rod 202h cannot drive the clamping block 204l. Under the action of the coil spring arranged in the supporting disc 204c, the rotating disc 204d can be reset to rotate, so that the sliding rod 204a drives the shifting block 204b to reset.

The number of the blocking block 205b is two, which are used for blocking the logistics box 104 below the removed logistics box 104, so as to prevent the logistics box 104 below from deviating.

[0068] When any one logistics box 104 needs to be taken out, the driving motor 201d is started to drive the four first threaded shafts 201b to rotate, so that the lifting column 201e drives the lifting plate 201f to move, so that the lifting plate 201f moves to the side of the logistics box 104 to be taken out. At this time, the moving motor 202b is started to drive the second threaded shaft 202a to move, and with the movement of the moving frame 202d, the first lever 202e is deflected under the extrusion of the logistics box 104 to be taken out, and the first spring 202f is stretched. With the movement of the moving frame 202d, the second lever 202h drives the push plate 203i close to the moving motor 202b to be pushed, so that the push plate 203i drives the insertion rod 203f to insert into the driving plate 203c, and the driving plate 203c drives the support plate 203d to slide out of the support frame 203b, thereby supporting the fixed strip 203j. At this time, the driving motor 201d drives the first threaded shaft 201b to rotate, so that the lifting plate 201f drives the support plate 203d to rise, so that the support plate 203d drives the fixed strip 203j to rise, so that the fixed strip 203j drives one of the logistics boxes on the top of the logistics box 104 to be taken out to move upward, thereby separating the two logistics boxes. With the movement of the moving frame 202d, the first lever 202e moves to the side of the logistics box 104 to be taken out. At this time, the logistics box 104 to be taken out is no longer extruded by the first lever 202e, and under the restoring force of the first spring 202f, the first lever 202e is deflected. Under the limiting action of the first limiting block 202g, the first lever 202e stops deflection. At this time, the moving motor 202b drives the second threaded shaft 202a to reverse, so that the moving frame 202d moves reversely. Through the reverse movement of the two moving frames 202d, the two first levers 202e push the logistics box 104 to be taken out to the platform of the lifting plate 201f.

[0069] At this time, the driving motor 201d can drive the four first threaded shafts 201b to rotate, so that the lifting plate 201f is lowered, and the vertical plate 203a and the support frame 203b on the top of the lifting plate 201f are lowered together until the support plate 203d drives the suspended logistics box 104 to fall on the bottom logistics box 104 or the support table 103. At this time, the support plate 203d and the fixed bar 203j are separated, the second threaded shaft 202a is reversed again under the action of the moving motor 202b, so that the moving frame 202d drives the second lever 202h to extrude the positioning plate 203g on the insertion rod 203f away from the moving motor 202b, so that the insertion rod 203f is inserted into the driving plate 203c, thereby driving the driving plate 203c to reset. The support plate 203d is retracted into the support frame 203b driven by the driving plate 203c, so that when the support frame 203b moves up and down, the support plate 203d will not hit the fixed bar 203j. At this time, the driving motor 201d can drive the four first threaded shafts 201b to rotate, so that the lifting plate 201f falls above the fixed plate 102. At this time, the moving motor 202b drives the moving frame 202d to move. When the moving frame 202d moves, it can drive the second lever 202h to drive the clamping block 204l, so that the clamping block 204l drives the carriage 204k to move, and the carriage 204k drives the side of the cable 204h to move. When the cable 204h is pulled, the reel 204f can be rotated, so that the reel 204f drives the rotating disc 204d to rotate, and the rotating disc 204d can drive the driving arm 204e to swing in the sliding groove of the sliding rod 204a, so as to drive the sliding rod 204a to move, thereby driving the sliding rod 204a to move, so that the sliding rod 204a drives the lever 204b to move, and the lever 204b pushes the logistics box 104 on the top of the lifting plate 201f away. The logistics box 104 pushed away will fall on the transmission belt arranged on the trolley body 101. The transmission belt can transport the logistics box 104 pushed down to the work station.

[0070] With the movement of the carriage 204k, the carriage 204k approaches the reset insertion block 204n, so that the reset insertion block 204n is inserted on one side of the clamping block 204l. The clamping block 204l is provided with an inclined slot. When the reset insertion block 204n is inserted into the inclined slot, the clamping block 204l is retracted into the moving frame 202d. At this time, the second lever 202h cannot drive the clamping block 204l. Under the action of the coil spring arranged in the support disc 204c, the rotating disc 204d can be reset to rotate, so that the sliding rod 204a drives the lever 204b to reset, thereby pushing the next logistics box 104.

[0071] The driving motor 201d and the moving motor 202b are controlled by the control system in the trolley body 101.
