First, Introduction of Automated Stereoscopic Warehouse
Automated three-dimensional warehouse is a new concept in logistics warehousing. The use of stereoscopic warehouse equipment can realize the rationalization of high-level warehouse, automation of access, and simplification of operation. Automated stereoscopic warehouse is a form of high technology level at present. The main body of the automated warehouse is composed of shelves, roadway stacking cranes, workbenches in (out) warehouses, automatic transportation in (out) and operation control systems. The rack is a building or structure of steel or reinforced concrete structure. The rack is a space of standard size. The roadway stacking crane travels through the roadway between the racks to complete the work of stock and pick-up. Computer and bar code technology are used in management.

Second, Components of Automated Stereo Warehouse
1. Shelf: Steel structure for storing goods. There are mainly two basic forms: welded shelf and combined shelf.
2. Pallets (containers): Appliances used to carry goods, also known as station appliances.
3. Roadway stacker: equipment for automatic access to goods. According to the structure form, it can be divided into two basic forms: single column and double column; according to the service mode, it can be divided into three basic forms: straight road, bend road and transfer vehicle.
4. Conveyor system: the main peripheral equipment of the three-dimensional storehouse, responsible for transporting goods to or from the stacker to remove goods. There are many kinds of conveyors, such as roller conveyor, chain conveyor, elevator, distributor, elevator, belt conveyor and so on.
5. AGV system: auto-steering car. According to its guiding mode, it can be divided into inductive guiding car and laser guiding car.
6. Automatic control system: the automatic control system that drives the equipment of the automatic stereo library system. Fieldbus is the main mode of control.
7. Storage information management system: also known as central computer management system. It is the core of the fully automated three-dimensional library system. Typical automated three-dimensional database systems use large database systems (such as ORACLE, SYBASE, etc.) to build a typical client/server system, which can be networked or integrated with other systems (such as ERP systems).

Third, Components of Automated Stereo Warehouse

1. Shelf
The design of shelves is an important part of the design of three-dimensional warehouse, which directly affects the area and space utilization of the three-dimensional warehouse.
(1) Shelf form: There are many forms of shelves, and the shelves used in automated warehouses are generally: beam shelves, bracket shelves, mobile shelves, etc. When designing, it can be reasonably selected according to the shape size, weight and other relevant factors of the cargo unit.
(2) Shelf size: Shelf size depends on the clearance between the cargo unit and the shelf column, cross beam (bracket). The same pair, to a certain extent, is also affected by the shelf structure and other factors.

2. Stacker
Stacker is the core equipment of the whole automated warehouse. It can carry goods from one place to another by manual operation, semi-automatic operation or full-automatic operation. It consists of frame (upper beam, lower beam, column), horizontal walking mechanism, lifting mechanism, cargo platform, fork and electrical control system.
(1) Determining the form of stacker: There are various types of stacker, including single-track roadway stacker, double-track roadway stacker, rotary roadway stacker, single-column stacker, double-column stacker and so on.
(2) The determination of stacker speed: According to the flow requirement of the warehouse, the horizontal speed, lifting speed and fork speed of the stacker are calculated.
(3) Other parameters and configurations: according to the warehouse site situation and user requirements, the positioning mode and communication mode of the stacker are selected. The configuration of the stacker can be high or low, depending on the specific situation.

Fourth, Advantages of Automated Stereo Warehouse System
1. Save the area of the warehouse and make full use of the space of the warehouse. Because the automated warehouse uses adopt the assembly of large warehouse shelves and the automated management technology make the goods easy to find, the construction of automated warehouses occupies less space than traditional warehouses, but the space utilization rate is large. In developed countries, improving the utilization rate of space has become an important assessment index for the rationality and advancement of the system. In today's advocacy of energy conservation and environmental protection, automated three-dimensional warehouse has a good effect in saving occupied land resources, but also will make the future development of warehousing a major trend.
2. Automation management improves the management level of warehouse. Automated warehouse uses use uses computer to manage goods information accurately and correctly, which reduces the errors that may occur in the storage of goods and improves work efficiency. At the same time, the three-dimensional automated warehouse realizes the motorization in the delivery of goods into and out of the warehouse, and the handling work is safe and reliable, which reduces the damage rate of goods. It can also make some goods with special requirements for the environment have a good preservation environment through special design, such as toxic and explosive goods, and also reduces the harm that people may suffer when handling goods.
3. Automated three-dimensional warehouse can form an advanced production chain and promote the progress of productivity. Professionals pointed out that, due to the high efficiency of storage, the automated warehouse can effectively connect the production links outside the warehouse and form an automated logistics system in the storage, thus forming a planned and arranged production chain, which greatly improves the production capacity.
