Among them, the three-dimensional warehouse based on PLC is one of the important equipment in automation control. This paper discusses in detail the modern large-scale enterprise in the universal use of automated warehouse design. First of all, from the column design and the structure design of several main mechanism, the operation mechanism of the crane is analyzed. The from stacking machine and the structure, stress analysis of the column is then deduced from the column of the bending moment and deflection relationship, and then gives the design of data check ultimately designed to meet under load and tall, thin column; focus on the design of the structure design of fork telescoping mechanism. First of all, through the analysis of fork diagram, bending deflection formula is deduced, shipment external structure and dimension of the fork, then design and check the parts inside the fork with size, final design to meet the requirements, a flexible, simple and convenient fork structure. And remove the appropriate motor and reducer; calculation of stacker crane lifting mechanism and the walking mechanism design is introduced in this paper, and to determine the size and motor, reducer selection; then, a small volume, high sensitivity, reliable action, the design scheme of the cranessafe organization of flexible device. This design through the use of appropriate PLC, and design the corresponding control system programming, running, debugging, and ultimately meet the design requirements.
