AUTOMATED SYSTEM FOR BOTTLE FILLING OF LIQUID MIXTURE USING PLC

Abstract

ABSTRACT Automating the routine tasks in the industries increases the productivity and reduces the probability of error in the system. Traditional methods of bottle filling involved placing bottles manually and filling it. This method is time consuming and expensive. This task needs separate manpower and thus is prone to errors. To automate the control of liquids and mixing two different liquids in defined proportion and finally filling the generated mixer in the bottles automatically and also to reduce human intervention, a PLC based automated bottle filling system is designed. In this bottle filling system, liquids kept in two different reservoir tanks are mixed in a third tank (overhead tank) and mixed liquid is filled in bottles, placed on the conveyor belt. In such process there is no need of labor so there is no human error. Without human error, the quality of product is better and the cost of production would definitely decrease. The implemented automated system has many features such as high level and low level indicators, emergency alarm creations for warning the operator etc. The ON/OFF controls of motors for controlling the liquid level, conveyor belt motor, operation and control of solenoid valve for filling the bottles etc are carried out by PLC programming through ladder logic.
