The pushing cylinder 111 drives the pushing rod 103 to push the rows of the packing boxes 5 to the top plate 305 which is flush with the upper flat plate 101, the slider 110 close to the left triggers the travel switch on the limiting block 109, and the push rod of the pushing cylinder 111 resets rightwards to trigger the magnetic switch at the bottom dead center of the pushing cylinder 111. The vertical moving cylinder 105 pushes the upper flat plate 101 to reset upwards, and triggers the top dead center magnetic switch of the vertical moving cylinder 105 to perform the next pushing and arranging operation.

5. When the stacking mechanism 3 is in an initial state, the push rod of the jacking cylinder 308 is located at the bottom dead center, and the upper surface of the box pushing rod 309 is flush with the top surface of the top plate 305 at the moment. When the row of packing boxes 5 is pushed to the top plate 5 by the pushing and arranging mechanism, the photoelectric switch on the top plate 5 is triggered. Subsequently, the rod of the lift cylinder 211 of the lift mechanism 2 is pushed out, and the top plate 305 reaches the lowest point. The jack-up cylinder 308 is then actuated to jack the box-pushing rod 309 upward and above the top plate 5.

6. After the top rod of the jacking cylinder 308 reaches the top dead center, the magnetic switch of the top dead center is triggered, and the box pushing rod driving motor 311 drives the screw nut 307, the jacking cylinder 308 and the box pushing rod 309 to move leftwards together, so that the packing box 5 on the top plate 305 is pushed out into the boxcar.

7. After the packing box 5 is pushed out of the top plate 305, the screw nut 307 triggers the position switch at the left end of the slide bar 312, the box pushing bar driving motor 311 drives the box pushing bar 309 to move rightwards, and triggers the position switch at the right end of the slide bar 312, and the box pushing bar driving motor 311 stops running. The jacking cylinder 308 acts to drive the box pushing rod 309 to downwards touch the bottom dead center magnetic switch of the jacking cylinder 308. The lifting mechanism 2 then drives the palletizing mechanism 3 upwards to its initial position in preparation for the next palletizing operation.

8. The height of the conveyor 4 can be increased along with the number of stacked layers, so that the packing boxes 5 can be sequentially stacked to different heights in the boxcar.
