RESUMEN
El moldeo rotacional o roto moldeo es el proceso de transformación del plástico empleado para producir piezas huecas en el que plástico en polvo o líquido se vierte dentro de un molde luego se l e hace girar en dos ejes biaxiales mientras se calienta. En este trabajo se establece un control para mantener estable la temperatura sin importar las perturbaciones y producir con calidad tinacos domésticos de 750 litros basados en esta técnica. En dicho control se utiliza un sensor de temperatura que permite saber en todo momento en que valo r se enc uentra; como actuador se utiliza un prototipo de servo válvula que permite el paso de gas al quemador que produce el calentamiento y finalmente todo esto está asociado a un sistema embebido basado en Arduino que permite cerrar el lazo y mantener el control dinámico de la temperatura.
Palabras Clave: Control, Temperatura, Embebido.
ABSTRACT
The rotational molding or roto molding is the process of plastic transformation used to produce hollow parts in which plastic in powder or liquid form it is poured into a mold that is rotated in two biaxial axes while it is heated. In this investigation, a control is established to keep the temperature stable regardless of the disturbances and produce quality domestic water tanks of 750 liters using this technique. In this control, a temperature sensor is utilized which allows knowing at all times what valu e it is in, as an actuator a servo valve prototype is used that allows the passage of gas to the burner that produces the heating and finally all this is associated to an embedded system based on Arduino that allows to close the loop and maintain the tempe rature control dynamic.
Keywords: Control, Temperature, Embedded.
