Automatic three-dimensional warehouse is a new concept in logistics warehousing.Using high-level warehouse rationalization, access automation and easy operation; automation is a high technical level.The main body of the automatic stereo warehouse consists of shelves, roadway stacking crane, in (out) library workbench and automatic transport in (out) and operating control system.Shelves are steel structure or steel concrete structure building or structure, the shelves are standard size space space, roadway stacking crane through the roadway between the shelves, complete the work of storage and pickup of goods.Computer and barcode technology are used in the management.With the rapid development of warehousing and logistics industry, automation stereo library is more and more favored by the enterprise users, but we need to consider multiple elements before custom automatic automation library, because automation stereo warehouse cost is relatively large, once built to change is more complex, it is not only to waste more cost, but also very time-consuming.The following strong summary of several elements about the automatic three-dimensional warehouse needs to be fully considered before the three-

dimensional warehouse construction:
I. Existing scale and structure of the warehouse.The scale and structure of the warehouse is the element that must be considered in the establishment of an automatic three-dimensional warehouse. The available height, width, length and pillars and other fixed facilities of the existing warehouse will affect the design of the three-dimensional warehouse. Of course, the larger the warehouse space, the more conducive to the advantages of the three-dimensional warehouse.However, some enterprises have begun to consider establishing an automatic three-dimensional warehouse before the warehouse was built, such as this situation is relatively easy for the design of the automatic three-dimensional warehouse.
II. Characteristics of the goods.The material, specification, weight and height of the goods pallet affect the determination of the tray specification, and the characteristics of the goods jointly determine the size of the automatic stereo tray space.

III. Design of goods warehousing and delivery.The quantity and location of goods entrances and exits are determined, and the nature of exit and warehousing (e. g.: whole plate, pick and out of storage).It is also necessary to determine the use characteristics of the tray, whether in-library turnover or in-factory turnover.
The working time and working efficiency of the automatic three-dimensional warehouse are also the elements that cannot be ignored.For example: Is 8 hours, 12 hours or 24 hours a day?The average daily warehousing volume and warehousing volume must be clear at the peak must also be clear.
V. Determine the library capacity (including the cache area)

Library capacity is the number of cargo units that can hold at the same time, which is a very important parameter for automated stereoscopic warehouses.Since the inventory cycle will be affected by many unexpected factors, the wave peak of the inventory can sometimes greatly exceed the actual library capacity of the automated stereoscopic warehouse.In addition, some automated three-dimensional warehouses only consider the capacity of the shelf area, and ignore the area of the cache area. As a result, the area of the cache area is insufficient, so that the goods in the shelf area can not come out, and the goods outside the warehouse can not enter.
In general, automation library is a complex project. Before construction, we must consider many factors comprehensively, and the more comprehensive we understand, the better, which is more helpful to the construction behind.
