What are the three-dimensional warehouse design planning? In the planning of active three-dimensional warehouse, the first consideration is inventory, power and cost.But sometimes the demand for inventory is high, and there is no power problem; sometimes it is power and cost.In addition, we should consider its applicability.The following points should be paid attention to when planning stereoscopic warehouse:
1. Basic data
Planning is based on basic data.No matter what kind of planning, it is meaningless to separate from the basic data, and it is impossible to judge whether the planning is good or bad.Many planners don’t understand this point and draw pictures as soon as they come up, which can’t solve the problem.
In the basic data, the important ones are inventory, delivery and receipt quantity, dismantling quantity, working time, SKU quantity, etc.Generally, these data should be referred to as historical data or peer data.The more accurate the basic data, the more reasonable the planning.
2. Load
Foundation: accounting should be carried out according to standards, rather than random selection.
Shelf bearing capacity: the use of finite element method for mechanical analysis, in which the seismic load is very important.
3. Storey height
The story height is very simple, for a novice, mistakes often occur.Floor height includes beam H1, pallet H2, goods H3, access space H4, security space H5, in addition to the bottom height and top height.Assuming that there is no understanding of the stacker, it is not a simple matter to calculate the storey height.
4. Front area and back area
It is necessary to know the structure of the stacker to select the standard of the front area and the back area.Suppose you are an inexperienced planner who can look at other people’s plans.Correctly understand the front area and back area of the warehouse, but also understand the requirements of the repair area.
5. Power
The power of stacker in automatic storage system can be calculated, and the calculation method is given in fem9.851 standard.The power of the stacker is a primary factor, but it is not simple to correctly understand how to move the power.Some planners are inexperienced and tend to focus only on one policy and ignore others.Sometimes the role of accounting is often unexpected.
6. Transportation system
As a peripheral supporting equipment, the planning of transporter is often more important and messy than the active three-dimensional warehouse itself, which is also more difficult.There are many skills for the selection of transporters. In addition to the traditional transporters, the more widely used ones are the tandem vehicle, circular tandem vehicle, AGV, etc.No matter what skills and equipment you choose, you should have a clear understanding of their application occasions and skill requirements.
Power matching should be considered in the planning of carrier system.Sometimes, the choice of transportation method and transportation speed has a great influence on the power of the transportation system.
7. Fire protection zoning
Fire zoning has a great influence on the planning of the active warehouse.For class C and II materials, the partition area with active spray is 3000 square meters, while the limit for an active three-dimensional warehouse is 12000 square meters.This is one of the reasons why stereoscopic libraries can’t be built very large.
There are many planning parameters for automated warehousing system.It is important for planners to achieve balance and applicability.Balance means that all planning policies should not be too high or too low.Too high a policy will constitute a waste, too low a policy will affect the talent of the whole system.Application means that the skills selected should be appropriate and not used for the purpose of application.
