Automatic Liquid Filling to Bottles of Different Height Using Programmable Logic Controller

Filling is a task carried out by a machine that packages liquid products such as cold drinks or water. Traditional methods of bottle filling involved placing bottles onto a conveyor and filling only one bottle at a time. This method is time consuming and expensive. The present work briefs about a machine that used to prepare automatic filling of liquid in to the bottle of different height is fully controlled by the PLC which acts as the heart of the system. The system sequence of operation is designed by ladder diagram and the PLC programming software. Sensor usually plays its vital part as an input signal transmitter for the PLC in the system. During this work sensor has been used to detect the bottle position that move along the conveyor belt at the low speed while the machine operates. The input signal that has been sent from the sensor to the PLC has being made as a reference. Signal in order to determine the output signal that exactly a same with the PLC programming language based on the user requirement. The entire system is more flexible and time saving.
