By providing the flipping and lifting mechanism 39, the bottom of the goods can be flipped and lifted in a timely manner during the lifting and waiting process of the goods, effectively preventing the goods from falling, ensuring the stability during the stacking process of the goods, and reducing the risk of damage to the goods.

[0027] Working principle of the present invention: When the ton bag with a tray at the bottom is transported through the conveyor line 1, it first reaches the shaping machine 2 station. After the ton bag arrives, the left and right shaping mechanisms 5 are started. The left and right shaping plates 24 move from both sides to the middle under the push of the second oil cylinder 25 to press the goods until they cannot be pressed any further, realizing the shaping of the goods in the left and right directions. At the same time, the lifting motor 18 of the front and rear shaping mechanism 4 works, and drives the front and rear shaping mechanism 4 to descend from the top to the bottom along the vertical guide rail 11 through the lifting mechanism 17. Then, the oil cylinder 16 of the front and rear shaping mechanism 4 pushes the shaping pressing plate 15 to move from the front and rear sides to the middle to perform front and rear shaping on the goods until it is in place. Next, the top oil cylinder 31 of the top pressing mechanism 6 pushes the top pressing plate 30 to descend from the middle to press the top of the goods to complete the top shaping. After shaping, the height of the goods can be compressed from 1.9 meters to 1.2 meters. The five-sided shaping function of the shaping machine can perform all-round shaping and adjustment on the goods.

[0028] The palletized goods after shaping continue to be transported through the conveyor line 1 and reach the bag stacking machine 3 station. After the goods arrive, the oil cylinder three 38 of the stacking mechanism 7 pushes the stacking clamping plates 37 to extend from both sides to clamp the goods. Then, the lifting motor of the lifting mechanism works, and the lifting mechanism drives the stacking mechanism 7 to rise along the lifting slide rail 32 to a height above the height of one package. At this time, the tray leaves the conveyor line 1. After the next tray of goods enters and arrives through the conveyor line 1, the first package between the stacking mechanisms 7 descends under the control of the lifting mechanism and is stacked on the second tray of goods to complete the stacking operation of two trays of goods.

[0029] After stacking is completed, the stacking and shaping mechanism 8 and the stacking mechanism 7 work together to perform secondary shaping on the stacked goods, further ensuring the neatness and stability of the stacked goods. During the entire stacking process, after the first pallet of goods is clamped and lifted off the pallet for a period of time, the lifting oil cylinder 41 of the flipping and lifting mechanism 39 at the lower end of the stacking mechanism 7 pushes the pallet 40 to flip, and the guide plate 43 on the pallet 40 moves along the guide groove 13. The pallet 40 flips and lifts the bottom of the goods to prevent the goods from falling during lifting and waiting, ensuring the smooth progress of the goods stacking operation.
