DEVELOPMENT OF PLC BASED CONTROLLER FOR BOTTLE FILLING MACHINE

The growth in Food industry and Healthcare industry has seen a rapid increase in demands of beverages as well as medicines. Precision while filling these beverage containers is required. Non-precision will not only lead the economic loss in the beverage industry but also a danger to consumer health in healthcare industry. A typical manufacturing facility of this kind will require precision as well as velocity in filling operation, to achieve both manually is tedious task. Also to operate manually in hazardous chemical industries is safety concern to workers. To make automated bottle filling machine to achieve both accuracy and speed in filling, is requirement of the time. This can be achieved by help of PLC programming and PID controller. This paper describes the application of PLC programming and PID controller in the field of bottle filling operation. In this paper PLC is used along with various sensors as input to the system and valves are used as output to the system. This paper describes about logic developed to sense the position of bottle on the conveyor and its condition, that is whether it is filled or not.
