Diseño y simulación del proceso de empaquetado de papa y tomate mediante un control por una interfaz HMI para el centro de producción agrícola Tunshi.

Abstract

The objective of this project was to design and simulate the potato and tomato packing process by means of a human machine interface (HMI) control for the Tunshi agricultural production center. For this purpose, we investigated the potato and tomato packaging process utilizing the documentary review technique to learn about the components involved in its automation, which are: the conveyor belt, the programmable logic controller (PLC), the HIM screen, the three-phase motor, five types of capacitive sensors and the pneumatic cylinder. We designed the potato and tomato packaging station utilizing SolidWorks and Siemens NX software, where we established measurements, materials and other characteristics of the products and packaging. After that, we simulated the process with Siemens NX, TIA PORTAL, Server EX and NETtoPLCsim software through trial and error. We designed the HIM for the control and visualization of the packaging with TIA PORTAL software. An interactive user interface was created, a production history was managed and the web interface was programmed with Node-Red and TIA PORTAL. As a result, it was possible to record order data and manage process and sensor information, achieving control from different computers. It is concluded that the operation of this station is possible and can be implemented. It is suggested to use components of the same brand in order to ensure and extend the useful life of the station.
