Diseño e implementación de un sistema de control con conexión IoT y aplicación móvil para una máquina de inyección de plástico marca Battenfeld

Abstract

In Colombia today the plastics industry has taken a lot of strength due to the daily use of products made of plastic, a large part of these products are manufactured by small and medium-sized companies where most of the machinery used in the process is operating with obsolete technology and little innovation. In supervision, these companies generally do not have access to quality automation due to the high cost of elements and labor, for this reason it is necessary to develop and implement innovation in low-cost technology in order to optimize resources and have better supervision. of process. The automation and start-up of a Battenfeld brand plastic injection machine for the company Mecaniplast located in Kennedy is presented, for its technological update it develops an App to carry out the supervision of units produced and operation time in real time of the process, thus optimizing the production process. Among the devices installed for technological adaptation there is a PLC, an HMI screen, an IOT microcontroller which interacts with the machine's PLC through the ModBus RTU industrial protocol and communicates over the internet with an app for monitoring the production. On the other hand, a PID position control system was designed and implemented for the closure of the mold, since it is required that it advance as quickly as possible but that it has a deceleration before reaching its end of travel so that it does not there is a sudden collision with the parts. As a result of the development of this project, it is possible to start up the plastic injection machine with a PID control system for the closure of the mold that provides greater performance and less wear of the mechanical parts. On the other hand, you get an application to monitor the production of the machine through the internet, which gives you a connection with the concept of the fourth industrial revolution.
