Repotenciación y automatización del sistema de control eléctrico para una máquina sopladora de plástico marca Putián de dos estaciones en Pika (Plásticos Industriales).

Abstract

In this project, the repowering and automation of the electrical system of a Putián blowing machine is carried out for the company Pika plasticos industriales, which is stopped in its production due to damage to its electrical part, automation system and HMI screen. In the degree work project, the plastic blowing process and the machines that carry out this procedure are investigated, especially the two-station blowing machine found in the Pika company. We present theory, operation and important features that helped implement the design for automation and repowering. The location of the blowing machine was specified and a technical survey was carried out that helped reinforce the problem. With the help of AutoCAD software we were able to design the electrical control and force plans, detailed results after repowering and optimization. The new HMI screen interface was programmed with the Tía Portal software, which helped us create a practical and simple interface where the operation areas and movements are displayed. Finally, in chapter 4 we have conclusions and recommendations.
