Liquid Level and Photoelectric Sensors Based Automatic Liquid Mixing and Filling Machine System using PLC

Today the application of PLC is more widely used in the digital world. There are many applications of PLC especially in the industrial. Normally, the PLCs that have been used at the industrial field are usually to control the machine or heavy machine in order to create an efficient production process. In this paper, a discussion about PLC application will be explained in more details and specified. A machine that uses to prepare automatic liquid mixing and filling machine system is controlled by Delta PLC which is also the heart of the entire system. The DVP 14SS2 from the Delta PLC types is used and WPL soft is used to write the ladder logic. The PLC can control many other electronic devices such as pump motor, level sensors, photoelectric sensor, conveyor belt, gear motor, solenoid valve, push buttons, relays and other devices. The main aim of the paper is to develop and test the real time implementation of PLC based liquid mixing and filling machine system. Firstly, start button is pushed. The liquids juice and water are mixed in the mixer tank by using valves. The level sensors know limited liquid levels and mixer motor starts stirring. The mixer motor is ON by timer. When the stirring process stops, the conveyor belt starts moving. When the cup passes photoelectric sensor, conveyor belt stops and then the pump motor fills the liquid mixture in the cup by timer. When the cup completes filling process, the pump motor closes and conveyor belt runs continuously. When another cup passes the photoelectric sensor, conveyor belt stops. Filling process operates again and again.
