Implementación de un sistema automático de envasado de líquidos para la Planta de Lácteos Tunshi.

Abstract

It was implemented an Automatic Packing System for Liquids, for the Dairy Plant “Tunshi”, it was selected the needed instrumentation for the construction of the machine for the Packing Process Liquids, optimizing resources. The mechanic, electrical, electronical, and pneumatic components, were dimensioned, for the automation of the system. The machine was built in Stainless Steel 304, Controlled by the Arduino microcontroller, and by a Programmable Logic Controller (PLC), which receive the data of the proximity sensors, presence and weight, of pushbuttons, which are processed and allow to control the actuators of the system through the use of the relay bank, power circuit and solid state relays. For the opening and closing of the filling valve, a Proportional Integral Derivative (PID) control was implemented, which allows to maintain the process pressure. The system is able to fill up to 210 packings of one liter in one hour, is controlled by a Man Machine Interface (HMI), designed in the Android open source operating system, with the Google tool, for developing of this kind of applications. The user interface communicates with the system through Bluetooth wireless technology and allows a fully automatic control of the packing process by optimizing the production times and resources in the Tunshi Dairy Board. It is recommended to verify the level of the reservoir tank in order not to have problems of filling.
