Implementación de un módulo de clasificación por materiales y tamaños con el PLC y pantalla táctil para el laboratorio de control y automatización de procesos industriales de la Escuela de Ingeniería Mecánica de la ESPOCH.

Abstract

In accordance with the need to update and improve the Automation of Industrial Processes laboratory in the School of Mechanical Engineering, Faculty of Mechanical Engineering, the following thesis was completed. The thesis is part of the completion of a degree to obtain the title of Mechanical Engineer and the thesis is as follows: ‘IMPLEMENTING A CLASSIFICATION MODULE FOR MATERIALS AND SIZES WITH A PLC AND TOUCH SCREEN FOR THE LABORATORY CONTROL AND AUTOMATION OF INDUSTRIAL PROCESSES FOR THE SCHOOL OF MECHANICAL ENGINEERING, ESPOCH ". The module allows future generations of students to approach the broad field of automation in a practical way by means of a PLC SIMATIC S7 - 1200 (Programmable Logic Controller) a conveyor belt with a 110 V CA motor, two double effect cylinders that act based on a signal sent by two monostable electro-valves 5/2, two optical sensors and an inductive sensor. A KTP600 Basic touch screen was used for the HMI (Human Machine Interface), allowing us to simulate the process of classification by materials and size, a process that was displayed on said touch screen. It should be emphasized that the connection between the PLC and the touch screen was performed via profinet through a profinet cable. The classification process can be performed in various ways by programming carried out via the program TIA Portal V13 (Totally Integrated Automation). The process of classification of cylinders with different kind of materials by size was performed using optical sensors positioned at different heights at the beginning of the conveyor belt. In order to perform the classification by material type, the inductive sensor is activated and detects the material and thus sends it to a different ramp. The application of automation and control in these process will allow the Faculty of Mechanical Engineering students to have a better understanding of how a HMI and PLC operator panel function, thereby determining the variables to be controlled through the correct use of optical, capacitive and inductive sensors, for later connection and programming, highlighting the student's ability to solve problems in the field of industrial production. For proper handling and maintenance in the module, the corresponding instructions based on criteria and recommendations from the manufacturer were produced. Practice guides were also created so that, with the supervision and support of the overseeing professor, the students will become familiar with and learn in a practical way the programming and simulation of the automation of various industrial processes that may present to them in their working life.
