With the rapid growth of your business volume in recent years, the material flow volume has also increased significantly, and relying entirely on the leasing of external storage resources can not meet the needs of business development. In order to solve the problems of scattered storage sites and low efficiency of delivery and delivery, you decided to invest in the construction of automatic warehouse in Langfang, Hebei Province as a distribution center for the northern market, introduce modern logistics technology and advanced equipment, and improve the level of logistics management and operation. The project has advanced design and efficient operation, which provides a strong logistics support for the rapid development of Liangyou.

I. Library layout and system composition
The Langfang automatic warehouse planned by you is mainly divided into four areas: storage area, storage area, sorting area and exit area. The specific logistics system is as follows:

automated warehousing technology, the main operation process of the automatic warehouse is as follows:
 1. Project highlights and effect
As a FMCG enterprise, Liangyou's demand for the logistics system is mainly reflected in two aspects: fast forward and fast exit, big progress and big out. First of all, fast entry and fast exit, FMCG products pay great attention to freshness management, and the produced products need to be sent to the sales terminal as soon as possible, so it puts forward high requirements for the warehousing efficiency of the logistics system, fast entry and fast exit. In addition, as the distribution center of the north, the average shipment of Liangyou Langfang Automation Warehouse is 200,000 boxes per day.
 In this regard, the system design of Liangyou Langfang automatic three-dimensional warehouse also has some unique aspects. For example, in order to ensure the storage efficiency and the reasonable utilization of equipment ability, the WMS system realizes the uniform distribution of various goods in the storage area according to the pre-set rules. At the same time, the unique design of the sorting area also has quite highlights, specifically shown in:

 1) The sorting area has two functions of picking and replenishment, and the forklift is responsible for sending the selected goods to the conveyor and replenishment;
 2) The sorting operation is completed manually. In order to avoid the interaction between forklift and staff operation, there are 4 channels set up in the sorting area, and the middle two are manual picking channels, and both sides are used for forklift handling, which improves the safety of the on-site operation environment.
