Propuesta de automatización de una máquina Granalladora de cilindros para envasado de Gas Licuado de Petróleo a través de LOGO V8.

Abstract

The present degree work proposes the automation of a cylinder shot blasting machine used for the packaging of liquefied petroleum gas, which works with a set of electric motors that require a sequential ignition to protect the internal components and ensure efficient operation. The design of the automation of the shot blasting machine consists first in identifying all the components that intervene in its operation; In this way, the electrical conductors of the main connection, its electrical protection system, the type of soft starter for high-power motors and the Logo 8 programmable logic controller together with its man-machine interface are dimensioned. For the elaboration of the electrical diagram, the Logo Soft Comfort V8 software is used, where the motors of the components and the turbines of the Shot Blasting Machine are controlled sequentially together with the configuration of the Logo TDE screen, which is responsible for executing the running commands, stop, state of the motors and identification of faults produced by activations of motor protectors. With this automation proposal, the shot blasting process is optimized by reducing electrical failures caused by faulty electrical elements and errors in the motor ignition sequence; therefore, the production indicators show compliance with the established goal.
