Description

Technical Field

[0001] The invention relates to the technical field of automatic stacking, and in particular to an automatic stacking device for a folding cart. Background Art

[0002] For many years, my country's bank vaults have had extremely strict management systems and operating requirements. Vault operations have always been mainly manual, with very few automated technologies and equipment. The relevant management systems also rarely take into account the needs of vault automation and intelligent equipment. Therefore, the current situation faced by bank vaults is high labor intensity, many risk points, and high management difficulty. With the development of the financial market, the deepening of financial reforms, and the changes in the financial environment in recent years, the above problems have become more and more prominent. The entry and exit of various types of goods managed by the vault are basically completed by "loading and unloading by hand, and moving by walking". Although some links have been partially mechanized and upgraded, such as sorting and moving links, for the entire vault, the various functional modules still need to rely on manual connection, and an effective closed loop has not been formed.

[0003] The existing technical solutions have defects. Unlike the stacking equipment of the present invention, the existing carts are stacked manually, with a small number of stacking layers, high labor intensity and low degree of automation. Summary of the invention
