Diseño e implementación de un sistema automatizado para una embutidora de cárnicos de la Facultad de Ciencias Pecuarias.

Abstract

The objective of the present research work was to implement an automatized system for a vacuum filler for meat processing of the Faculty of Animal Science, this machine was installed at the Meat Production Center of the “Escuela Superior Politécnica de Chimborazo” in order to facilitate its operation and to guarantee the physical integrity of students and teachers. With the aim of carrying out its elaboration, it was used the modeling of systems through the determination of its components, as well as the verfication and correction of functioning errors. This automatized system deals with the substitution of an Oleo hydraulic automatic System over the manual hydraulic mechanisms. Afterwards, it controls the linear speed of the hydraulic cylinder and the system pressure through a programming on the platform of control Arduino which receives signals of the ultrasonic and pressure sensors. The programming also sends information to every one of the actuators: the stepper motor whose main function is the opening or closing of the pressure regulation valve, and the coils of the directional solenoid valve; for the control of the thrust and return of the cylinder. For the opening or closing of the valve, it was implented a Fuzzy controller that allows to maintain the pressure in an established range according to the type of cold meat to be processed, and to maintain stable the linear speed of the cylinder, controlled and monitored in a HMI display. As a conclusion, there was an increment of 33,33% in the machine performance, optmizing time and avoiding forced stops in the machine. It is recommended to analyze in detail the process before the automation, and to perform preventive and/or corrective maintenance in the machine once the project is finished.
