Abstract


As China's economy is booming , the demand of industrial brushes in short supply in the state . Volume Brush is the main equipment for the manufacture of industrial brushes , relatively slow development in the country , immature volume Brush manufacturing process , the quality of the production of industrial brushes . Its technology has been hot and difficult industry research . The volume brush machine production line is divided into the front desk to send material and background welding two parts . Microcontroller and programmable controller are two common implementations of discrete control systems . This article uses discrete control technology background welding part , at a critical part of the design and realization . This article works as follows: SCM control technology in-depth analysis and research , automation control requirements of the welded part of the background , select 51 series, for the system to switch the type of input device characteristics and design limit bit switches, photoelectric switches , as well as the magnetic switch input circuit . Analysis and relay type of output device at the same time , the relay output circuit design for the system . This article uses the 8051 volume Brush automated design , and in-depth analysis of the strengths and weaknesses of the design . The programmable controller , programmable controller DC input , AC input , programmable controller transistor output , relay output and the corresponding input / output type internal circuit depth analysis and research on this basis on the combined volume control requirements brush Mitsubishi FX1S-30MR programmable controller ladder design and realization of each control system requirements, and system security , while the design of the solenoid valve gas line connected to the system as well as within the distribution cabinet traces . In order to better real-time monitoring and human-computer interaction , design the COOLMAY touch screen configuration screen . FX1S-30MR programmable controller to achieve automatic control of the welding part of the background of the volume Brush After repeated simulations and site commissioning , the system is stable, reliable , and successfully put into production .
