Implementación de un sistema de control mediante varidores de frecuencia y encoders para una máquina empaquetadora de galletas de la empresa Corporación Superior S.A.

Abstract

The execution of this project responds to the need to increase the production capacity of a cookie packing machine of Corporación Superior S.A., for which a new Control System will be installed, together with a human-machine interface. In the implementation of the project, two frequency inverters (VFDs), encoders, a Programmable Logic Controller (PLC), control elements, indicating elements, protection devices, sensors and actuators are considered. The synchronization of the packets is performed by the variable frequency drives and their Electronic Line Shaft (ELS) function, where a closed loop of PI control is implemented, in order to regulate the speed of the motors to synchronize them. Control algorithms were developed as well as a human-machine interface (HMI), in order to command the machine, in addition to allow the visualization and monitoring of the packaging process.
