[0003]

The work of stacking containers on a trolley must be carried out to the height of a human from the viewpoint of loading efficiency. , But average 15
The burden of lifting and stacking kilotonous containers could not be neglected, especially when stacking on the upper stage, which was a very heavy labor with back pain.

[0004] In view of the above, the present invention provides a container stacking system capable of automatically stacking containers conveyed on a conveyor containing finished products of loose picking using a height difference without using human labor. It is intended to provide a device.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a container stacking apparatus for automatically stacking a container conveyed by a conveyer moving upward to a predetermined height on a carriage on an elevating platform from above. The container stacking device includes container holding means for holding the container on the transport conveyor from both sides in a direction orthogonal to the transport direction, container lifting means for lifting the held container, and a container for placing the lifted container on a trolley. Mounting means, elevating means which lowers the elevating platform by the height of one container each time the container is placed on the trolley, and lowers the elevating platform to below the floor when the container reaches a predetermined height,
It has a pressing means for pushing the bogie lowered on the floor to the side of the hoist, the hoist being removably engaged with the bogie, and a positioning means for stopping the bogie at a predetermined position of the hoist. It is characterized by having.

In the present invention having the above structure, the cart is placed on the floor, stopped at a predetermined position by the positioning means of the elevator, and the elevator stopped below the floor is raised by the elevator and placed on the floor. The carriage is placed on the elevator and raised to the level of the upper conveyor. The container on the conveyor is clamped at the end of the conveyor by container clamping means in a direction perpendicular to the conveying direction of the conveyor, and the clamped container is lifted by container lifting means, and the container is trolleyed by the container mounting means. Placed on top.

When a container is placed on the trolley, the lifting platform is lowered by the height of one container by the lifting means to prepare for the next stacking of containers. Then, the containers are sequentially and repeatedly stacked, and when the container reaches a predetermined height, the elevator descends, leaving the truck on the floor, and the elevator stops below the floor. Then, the engagement of the positioning means of the truck is released. When the elevator is stopped under the floor and the positioning means is disengaged, the truck on which the containers are stacked is pushed out to the side of the elevator by the pressing means provided on the floor, and a series of operations is completed.
