[0060] S1. Convey the horizontally placed boxed products to the horizontal material turnover machine through the horizontal material conveyor;

[0061] S2. Detect the position of the boxed products through the inductive sensors on the horizontal material turnover machine, and turn over and erect the horizontally placed boxed products through the horizontal material turnover machine, and convey the vertically placed boxed products to the vertical material conveyor;

[0062] S3. Use a vertical material conveyor to transport the boxed products placed vertically to the pushing position, and use two pushing mechanisms to push the boxed products transported to the pushing position into the corresponding material arranging machine for arranging. Detect the working process of the pushing mechanism through the induction sensors on both sides of the pushing mechanism, and detect whether all the boxed products are arranged through the induction sensor on one side of the material arranging machine;

[0063] S4. Use an automatic box opening machine to pull the flat cardboard box into a box shape and transport it to the centering conveyor. Transport the cardboard box under the box feeding mechanism through the centering conveyor, and open the four sides of the cardboard box and keep them open through the box feeding mechanism;

[0064] S5. Use a packing and palletizing robot to grab and transport the boxed products arranged on one of the material arranging machines above the box feeding mechanism for packing. Then, use the packing and palletizing robot to suck and transport the partitions on the partition machine above the boxed products that have been packed to separate the boxed products in the cardboard box. Then, use the packing and palletizing robot to grab and transport the boxed products arranged on the other material arranging machine above the box feeding mechanism for packing to complete the packing;

[0065] Specifically, first move the fixture on the packing and palletizing robot to the first material arranging machine so that the front side plate, rear side plate, left side plate, and right side plate on the fixture respectively correspond to the four sides of the boxed products arranged on the first material arranging machine. Then, drive the front side plate and rear side plate to clamp the front and rear of the boxed products through the front side cylinder and rear side cylinder, drive the left side plate and right side plate to clamp the left and right of the boxed products through the left side cylinder and right side cylinder, and then grab and transport the boxed products above the box feeding mechanism. The front side cylinder and rear side cylinder drive the front side plate and rear side plate to release the boxed products, and the pushing cylinder drives the fixture bottom plate to move downward, that is, drive the left side plate and right side plate to clamp the boxed products and move downward into the box. Then, two pressing cylinders drive two pressing blocks to move downward to press out the boxed products and install the boxed products in the cardboard box. Then, the fixture is lifted upward, and the left side cylinder and right side cylinder drive the left side plate and right side plate to release; then, use the suction cup to suck and transport the partitions on the partition machine above the boxed products that have been packed to separate the boxed products in the cardboard box, and then repeat the above operations to grab and transport the boxed products arranged on the second material arranging machine above the box feeding mechanism for packing to complete the packing;
