Design of Automatic Control System in Filling Machine for Liquid Soy Sauce Based on Mitsubishi Plc And Hmi

Abstract

A filling machine is a machine used to fill liquid products into packaging. This machine is an important component in the food and beverage processing industry, pharmaceuticals, cosmetics and other industries that require filling products into packaging quickly and efficiently. Based on general observations in the field, entrepreneurs in the field of packaging liquid product filling are still carried outconventionally with human labor in the filling process. So, in the end manually filling soy sauce products can cause a decrease in filling volume, consistency, speed and cleanliness which can affect the quality of the final product. In designing the control system for filling machines, three working modes are created, namely Manual Mode, Semi-Manual Mode and Automatic Mode. Manual and semi- manual work modes, the function is used if the automatic work system has an error or system damage, then the manual and semi-manual work mode functions will be activated. This HMI is also used as a control system for each machine working mode, and also for monitoring. Monitoring via HMI can be seen on the indicators of each component, making it easier to identify damage or errors in each component. In testing this filling machine, it is carried out by comparing the liquids to be filled, namely by using air and soy sauce into packaging bottles because there are differences in the viscosity of the liquids.
