Diseño e implementación de una estación de posicionamiento en tres ejes con probetas de distintos materiales y tamaños con PLC para el laboratorio de control y automatización de procesos industriales de la Facultad de Mecánica de la ESPOCH

Abstract

A positioning station was designed in three axes with samples of different materials and sizes with PLC for laboratory of the Industrial Process Automation and Control of the Mechanical Engineering Faculty at the ESPOCH, as a teaching station will provide an important means for students learning, because this equipment is costly to purchase. The station was built using three motion axes with aluminum worm gears, using 24V motors. For the structure were used the aluminum profiles. The design of the control was made with 1 mm metallic sheet, will be placed within in the S7-1200 PLC, HMI, switch, power supply and input and output card, besides the power switch and the fuse. DB-25 cables were used to interconnect the devices. In addition, a wireless controller for handling station was performed. It was programmed in the TIA Portal software in order to make the three movements by placing the sampling tubes in specified positions for the process. An operating manual was developed which will allow us not only giving a good management of the station, but also a controlled maintenance. We recommend to program by knowing the spatial location so that there is no structural or electrical equipment damage by an unexpected movement. This station will help to students in their professional development.
