Description

Technical Field

[0001] The present invention relates to the field of warehousing technology, and in particular to a stacked box warehousing system, and a warehousing and unwarehousing method. Background Art

[0002] When the storage system receives a cargo entry instruction, the cargo box is transported to the designated location via conveyor lines, elevators and other conveying devices, and the shuttle car picks up the cargo box and places it in the designated cargo position on the shelf to complete the cargo storage work; when the storage system receives a cargo exit instruction, the shuttle car moves to the designated cargo position to pick up the target cargo box, and transports it to the designated location, and then transports it out of the warehouse via elevators, conveyor lines and other conveying devices. In order to improve the efficiency of cargo box entry and exit, at least two cargo boxes can be stacked together vertically for transportation. However, in the process of stacking at least two cargo boxes together for transportation, it is easy for the cargo boxes to be misaligned or skewed due to inertia when moving on conveyor lines, elevators and shuttle cars, and even the upper cargo box may fall, affecting the stability of subsequent cargo box stacking. Summary of the invention

[0014] In addition, the present invention also provides a storage method for a stacked box storage system, which utilizes the stacked box storage system and includes the following steps:

[0015] S1, multiple cargo boxes enter the conveyor line in sequence;

[0016] S2, stacking at least two cargo boxes vertically and gluing them together;

[0017] S3, transporting at least two stacked and bonded cargo boxes to a storage area.

[0018] The present invention also provides a method for outbound storage of a stacked container storage system, which utilizes the stacked container storage system and includes the following steps:

[0019] S1. Move at least two stacked and bonded cargo boxes to be shipped out from a designated cargo position;

[0020] S2, pulling apart at least two cargo boxes bonded together by means of a warehouse-out unstacking device;
