[Abstract]:Flexible automatic production technology is referred to as flexible manufacturing technology. It takes process planning as the guide and numerical control technology as the core. It automates the process, manufacture, assembly and inspection of various kinds and batches of enterprises. Advanced production technology for sorting and other processes. Because of its high efficiency, flexibility and short production preparation time, flexible automatic production technology has become the basis of advanced manufacturing systems such as agile manufacturing, concurrent engineering, lean production and intelligent manufacturing. Flexible automatic production technology is the main means for the machinery manufacturing industry to adapt to the dynamic demand of the market and the rapid updating of the products. It is also the basic technology of the advanced manufacturing technology. Based on the design of production automation production line of Huzhou Sunshine Automation equipment Co., Ltd., and flexible automation production line technology as carrier, this paper designs a set of production automation production line based on PLC control. Automatic production of different colors and materials (metal and non-metal) objects flexible control automatic sorting system. The research object includes the detection unit and sorting unit in the field control, which can transport the processed objects, sort out and classify the different materials and colors, and realize the independent and on-line operation of each unit. The system adopts PLC (Programmable Logic Controller) technology, sensor detection technology (including inductance sensor, capacitance sensor, color sensor, etc.), output actuator (including cylinder, solenoid valve, etc.) Related technologies such as indicator lamp, transmission system (DC deceleration motor, network on-line control system, man-machine interface, etc.) Finally, the whole process control and process monitoring of automatic sorting system is realized. (1) the whole design method and train of thought of automatic sorting system are studied. (2) PLC is adopted as the core controller of automatic sorting system. The control system is the core part of the flexible automation production line. In order to meet the control requirements, the design takes PLC as the control core. The automatic sorting control process is realized by a program written by PLC. The functions of data storage and archiving in WinCC configuration software are studied. The functions of alarm recording and recording, and real-time observation of dynamic working picture are studied. The system uses PROFIBUS-DP network communication, upper computer S7-300 as master station and two S7-200 slave stations to realize real-time communication between upper computer and lower computer.
