The design steps for an AutomaticStorage & Retrieval System are generally divided into the following steps:
1. Collect and study user's original data, clarify the goals that the user wants to achieve, including:
(1). Clarify the process of connecting automated three-dimensionalwarehouses with upstream and downstream;
(2). Logistics requirements: The maximum amount of inbound goods entering the warehouse upstream, the maximum amount of outbound goods transferred to downstream, and the required storagecapacity;;
(3). Material specificationparameters: number of material varieties, packaging form, outer packaging size, weight, storage method, and other characteristics of other materials;
(4). The on-site conditions and environmental requirements of the three-dimensionalwarehouse;
(5). User's functionalrequirements for warehousemanagement system;
(6). Other relevant information and special requirements.
2. Determine the main forms and related parameters of automated three-dimensionalwarehouses
After collecting all the original data, the relevantparameters required for the design can be calculated based on these first-hand data, including:
① Requirements for the total amount of incoming and outgoing goods in the entire warehouse area, i.e. the flowrequirements of the warehouse;
② The externaldimensions and weight of the cargo unit;
③ The number of storage spaces in the warehousestorage area (shelf area);
④ Based on the above three points, determine the number of rows, columns, and tunnels of the shelves in the storage area (shelf factory) and other related technicalparameters.
3. Reasonably arrange the overalllayout and logistics diagram of the automated three-dimensionalwarehouse
Generally speaking, automated three-dimensionalwarehouses include: inbound temporary storage area, inspection area, palletizing area, storage area, outbound temporary storage area, pallet temporary storage area, unqualified product temporary storage area, and miscellaneous area. When planning, it is not necessary to include every area mentioned above in the three-dimensionalwarehouse. It is possible to reasonably divide each area and add or remove areas according to the user's process characteristics and requirements. At the same time, it is necessary to consider the material flow process reasonably, so that the flow of materials is unobstructed, which will directly affect the ability and efficiency of the automated three-dimensionalwarehouse.

(6). Other relevant information and special requirements.
4. Select the type of mechanical equipment and related parameters
(1). Shelf
The design of shelves is an important aspect of three-dimensionalwarehouse design, which directly affects the utilization of warehouse area and space.
① Shelf form: There are many forms of shelves, and the shelves used in automated three-dimensionalwarehouses generally include: beam shelves, cow leg shelves, mobile shelves, etc. When designing, reasonable selection can be made based on the externaldimensions, weight, and other relevantfactors of the cargo unit.
② The size of the cargocompartment: The size of the cargocompartment depends on the gap size between the cargo unit and the shelf column, crossbeam (cow leg), and is also influenced to some extent by the shelf structure type and other factors.
(2). Stacker crane
Stacker crane is the core equipment of the entire automated three-dimensional warehouse, which can transport goods from one place to another through fully automated operation. It consists of a frame, a horizontal walking mechanism, a lifting mechanism, a cargo platform, forks, and an electrical control system.
① Determination of stacker crane form: There are various forms of stacker cranes, including single track aisle stacker cranes, double track aisle stacker cranes, transfer aisle stacker cranes, single column stacker cranes, double column stacker cranes, and so on.
② Determination of stacker crane speed: Based on the flow requirements of the warehouse, calculate the horizontal speed, lifting speed, and fork speed of the stacker crane.
③ Other parameters and configurations: Select the positioning and communication methods of the stacker crane based on the warehouse site conditions and user requirements. The configuration of the stacker crane can be high or low, depending on the specific situation.
(3). Conveyor system
According to the logistics diagram, choose the appropriate type of conveyor, including roller conveyor, chain conveyor, belt conveyor, lifting and transferring machine, elevator, etc. At the same time, the speed of the conveying system should be reasonably determined based on the instantaneous flow of the warehouse.
(4). Other auxiliary equipment
According to the warehouse process flow and some special requirements of users, some auxiliary equipment can be added appropriately, including handheld terminals, forklifts, balance cranes, etc.
4. Preliminary design of various functionalmodules for the control system and warehousemanagement system (WMS)
Design a reasonable control system and warehousemanagement system (WMS) based on the warehouse's process flow and user requirements. The control system and warehousemanagement system generally adoptmodular design, which is easy to upgrade and maintain.
5. Simulate the entire system
Simulating the entire system can provide a more intuitive description of the storage and transportation work in the three-dimensionalwarehouse, identify some problems and deficiencies, and make corresponding corrections to optimize the entire AS/RS system.
Detailed design of equipment and control management system
Lilan will comprehensively consider various factors such as warehouse layout and operational efficiency, fully utilize the vertical space of the warehouse, and deploy an automated warehousing system with stacker cranes as the core based on the actual height of the warehouse. The product flow in the warehouse area of the factory is achieved through the conveyor line at the front end of the shelves, while cross regionallinkage is achieved between different factories through reciprocating elevators. This design not only significantly improves circulationefficiency, but also maintainsdynamic balance of materials in different factories and warehouses, ensuring the flexibleadaptability and timelyresponsecapability of the warehousing system to various demands.
In addition, high-precision 3D models of warehouses can be created to provide a three-dimensionalvisual effect, helping users monitor and manage automated equipment in all aspects. When equipment malfunctions, it can help customers quickly locate the problem and provide accurate fault information, thereby reducing downtime and improving the overallefficiency and reliability of warehousing operations.
