Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a logistics system including an automatic driving truck and a truck elevation system,

The present invention relates to a logistics system, and more particularly, to a logistics system that uses a self-propelled truck, a truck lift, a truck rotation device, and a truck moving rail on which a truck is placed, The present invention relates to a logistics system including an autonomous traveling bogie and a bogie lifting system capable of effectively storing and dispatching goods.

The logistics warehouse is equipped with a rack (rack) for storing goods. Stacker cranes are used when stacking items loaded in a vans in racks or loading rack-mounted objects in vans. For stacking and shipping goods, the stacker crane must travel between the entrance (entrance and exit) and the rack. Until the stacker crane completes the previous work of the item, the forklift and other logistics equipment must remain on standby for the loading of the next cargo. As a result, it takes much time to load and unload the cargo. In addition, since the logistics equipment is left in the standby state, unnecessary equipment is injected in a double manner.

Once racked, the rack occupied the place until it was shipped, hindering efficient use of the rack. This is because the bottom of the article is not divided into the warehousing, storage and warehousing areas.

When picking up goods from a vans and moving them to a rack, they use forklifts because it is common for freight cars to be unloaded while waiting at the entrance to the warehouse without having to come directly into the warehouse. When the warehouse is on the first floor, it is possible to carry the goods with the freight car standing at the entrance of the warehouse. However, the warehouse is made up of multiple layers and the goods are stored in the other floor There is a disadvantage that the object is picked up from the lorry on the first floor and transported to the elevator, the object is moved to the floor where the rack is located through the elevator, and then transferred to the rack using the forklift.
