When designing an automated warehouse, the main considerations are inventory, efficiency and cost. However, sometimes there is a high demand for inventory and no efficiency problem; Sometimes efficiency and cost. In addition, consider how applicable it is. The following are the points for attention when designing automated warehouse:
1. Basic data
The design is based on basic data. No matter what design, it is meaningless without basic data, and it is impossible to judge whether the design is good or bad. Many designers do not understand this and draw pictures at the beginning, which cannot solve the problem.
The important items in the basic data are inventory, receipt/shipment quantity, split quantity, working time, SKU quantity, etc. Generally, these data should be referred to historical data or peer data. The more accurate the basic data, the more reasonable the design.
2. Load
Bearing capacity of foundation: it shall be calculated according to the specifications, not determined at will.
Shelf bearing capacity: mechanical analysis is carried out by using the finite element method, in which the seismic load is very important.
3. Storey height
The floor height is very simple, and it is easy for a novice to make mistakes. The floor height includes beam h1, tray h2, cargo h3, access space h4, security space h5, as well as the bottom floor height and top floor height. It is not easy to calculate the floor height without understanding the stacker.
4. Warehouse front area and warehouse rear area
To select the size of the front area and the rear area of the warehouse, it is necessary to understand the structure of the stacker. If you are an inexperienced designer, you can refer to others' designs. Correctly understand the front and rear areas of the warehouse, as well as the requirements of the maintenance area.
5. Efficiency
The efficiency of the stacker can be calculated, and the calculation method is given in the FEM9.851 standard. The efficiency of the stacker is a major factor, but it is not easy to correctly understand how to improve the efficiency. Some designers are inexperienced and tend to focus on one indicator while ignoring other indicators. Sometimes the calculation results are unexpected.
6. Conveying system
As a peripheral supporting facility, the design of conveyor is often more important and complex than that of automated warehouse itself, and its difficulty is also greater. There are many technologies used for conveyors. In addition to traditional conveyors, shuttle cars, circular shuttle cars, AGV, etc. are now widely used. No matter what technology and equipment are used, their application occasions and technical requirements should be understood clearly.
The design of conveyor system should also consider the matching of efficiency. Sometimes, what kind of conveying form and conveying speed is used has a great impact on the efficiency of the conveying system.
7. Fire compartment problems
Fire compartment has a great influence on the design of automated three-dimensional warehouse. For Class III and II materials, the partition area with automatic spraying is 3000 square meters, while an automated warehouse is limited to 12000 square meters. That's why Stereoscopic library One of the reasons why it can't be built very much.
There are many design parameters of automated warehouse. It is important for designers to achieve balance and applicability. Balance refers to each design index, and some indexes should not be too high or too low. Too high indicators will cause waste, and too low indicators will affect the ability of the whole system. Applicability means that the technology used should be appropriate, not applied for application. The designers in the early stage may not understand the adaptive occasions of automated warehouse, and there are many cases of misuse.
