Referring to fig. 4, the delivery end of the container conveyor 400 of the present invention is provided with a palletizing mechanism 100. The container conveying belt 400 continuously conveys the containers to the stacking mechanism 100, and the containers are stacked into the container rows with the preset specification in the stacking mechanism 100, so that the automatic operation of unstacking and stacking of the containers is realized, a large number of manual posts are replaced, the stacking of the containers is standard, the operation efficiency is high, and the operation amount in unit time is increased.

Referring to fig. 5, the stacking mechanism of the invention comprises a row assembly 1 and a box receiving assembly 2;

referring to fig. 6, the row assembly 1 has a conveying roller group 4 for conveying containers, and the conveying end of the conveying roller group 4 is provided with a baffle plate 41; the box baffle 41 blocks the containers, and a plurality of containers are aligned in a row. The side surface of the conveying roller group 4 is provided with a box pushing plate 42; a number of containers arranged in a predetermined length are pushed to the container receiving assembly 2. The push plate 42 can be pushed by an air cylinder. The conveyor roller set 4 is connected to the container conveyor 400.

A row assembly 1 for aligning a plurality of containers in a predetermined length column; the length of the cargo box column does not exceed a certain preset value; the predetermined value of the present invention may be the inner width of the container, the width of two opposing walls of the storage warehouse, or the entrance width of a certain enclosed storage space. The number of containers in the row of containers is determined based on the predetermined value and the specification of the containers (e.g., the length or width of the containers), and the length of the row of containers is usually slightly less than the predetermined value for smooth loading.

Due to the different specifications of the containers, the situation that the preset value cannot be divided by the length or the width of the container exists; if one less container is placed, the clearance between the container column and the walls (or walls) is too large, and the container risks toppling.

Therefore, in order to avoid the gap from being too large, the orientation of some containers needs to be adjusted, for example, in a container row arranged in the width direction, the orientation of a certain container needs to be adjusted to the length direction, so that the gap is effectively reduced, and the containers are prevented from falling in the transportation or storage process. A lifting plate 44 is arranged above the conveying roller group 4, a direction adjusting sucker 43 is arranged on the lifting plate 44, and according to the preset adjusting mode of the specification of a container, the direction adjusting sucker 43 sucks up a certain container, rotates 90 degrees and then puts down the container to complete the adjustment of the direction.

The direction-adjusting suckers 43 can be arranged in one group, two groups, three groups or more groups according to actual needs.

Furthermore, a stop member 45 is arranged at a preset position of the conveying roller group 4, and when the number of the containers passing through reaches the requirement of the container row, the stop member 45 extends out to stop the containers which are continuously conveyed; after the previous column of containers is pushed out, the dam 45 is retracted and the new column is formed. The dam 45 may be extended or retracted in a manner known in the art, such as by a pneumatic cylinder, electric cylinder, or lead screw drive.

Referring to fig. 7, the drop box assembly 2 has a box pallet 51 that moves in the vertical direction; the box pallet 51 receives the rows of containers pushed out from the row unit 1 and lowers slightly more than the height of the rows of containers until a predetermined number of rows of containers are received to form a row of containers.

After each row of containers has been formed, the whole is removed by means of a trolley 3 and fed into the container.

The height of the container row is set according to the specification of a specific container and the height of the container; such as 1, 2 or 3 rows of containers depending on the height of the container.

The box receiving assembly 2 comprises a conveying chain 5 which rotates circularly in the vertical direction, and the box supporting plate 51 is fixed on the conveying chain 5; further, the junction box assembly 2 further comprises a buffer plate 52; when the container receiving assembly 2 pushes out the container row, the buffer plate 52 extends out and slowly retreats along with the pushing-out stroke of the container row until the container row is stably placed on the box supporting plate 51.

The box supporting plate 51 and the buffer plate 52 are provided with supporting strips arranged at equal intervals; when the box supporting plate 51 and the buffer plate 52 meet, the supporting strips of the box supporting plate 51 and the buffer plate 52 pass through the supporting strip gaps of the other supporting plate, and the non-contact passing of the box supporting plate 51 to the buffer plate 52 is realized.
