Resumen
La propuesta consiste en desarrollar e implementar una lógica de Programación basado en detectar fugas y microporosidades en los envases PET (Tereftalato de Polietileno) después que salgan de la máquina de elaboración. Con el motivo de entregar un buen servicio de calidad a los proveedores que venden este tipo de envases.
La finalidad de la propuesta es realizar mediciones de presión al envase, a través del método diferencial de presión, donde se realiza una comparación entre la presión que se inyecta a la entrada del envase y la presión que estará en el interior del envase. Para esto se propone elaborar un tablero maqueta de Electricidad & Control, para las pruebas que se realicen al sistema, en donde tendremos los componentes que utilizaremos de una forma ordenada y contribuyendo a la identificación de los voltajes de alimentación que se utilizaran en la propuesta.
Para obtener las señales de presión se requieren dos sensores de Presión con señal de salida análoga, que después será procesada por un PLC (Controlador Lógico Programable), a través de un módulo de entrada analógica. En la lógica de programación se realizará el escalamiento de estas señales, luego de establecer los escalamientos se obtendrá la presión necesaria de trabajo para el envase, de acuerdo a ese procedimiento de prueba y error para el umbral de trabajo. En la lógica de programación se pasará a realizar las comparaciones de las señales del sistema para determinar las condiciones de estanqueidad del Envase.
The proposal consists of developing and implementing a programming logic based on detecting leaks and microporosities in PET (Polyethylene Terephthalate) containers after they leave the processing machine. With the purpose of delivering a good quality service to suppliers that sell this type of packaging. The purpose of the proposal is to make pressure measurements to the container, through the differential pressure method, where a comparison is made between the pressure that is injected at the entrance of the container and the pressure that will be inside the container. For this purpose it is proposed to make a mock-up of Electricity & Control, for the tests that are carried out in the system, where we will have the components that we will use in an orderly way and contributing to the identification of the power voltages that will be used in the proposal. To obtain the pressure signals, two pressure sensors with analog output signal are required, which will then be processed by a PLC (Programmable Logic Controller), through an analog input module. In the logic of programming will be made the scaling of these signals, after establishing the escalations will obtain the necessary pressure of work for the container, according to that procedure of trial and error for the threshold of work. In the programming logic, the comparisons of the signals of the system will be carried out to determine the sealing conditions of the container.
