Diseño, simulación y desarrollo de un prototipo académico del proceso de fabricación de papel ecológico mediante PLC y HMI

Abstract

This project develops an automated system for training and training analysis, the production process of ecological paper using recycled materials. The system incorporates industrial control tools through a Siemens S7-1500 PLC, physical variable sensors (such as temperature and humidity), a variable frequency drive and an HMI for live monitoring. The control logic is designed in stages, incorporating PID loops to optimize parameters such as humidity in the drying phase. The simulated prototype represents, in a controlled environment, the complete recycled paper production cycle, allowing the system performance to be adjusted through parameters such as process efficiency and the amount of raw material available. This model provides a useful platform for industrial automation practices, sustainability and performance evaluation under different operating conditions, and is scalable to pilot plants or technical training systems. From a didactic approach, the project strengthens hands-on learning in controller programming, device implementation, HMI monitoring and the creation of sustainable processes. It thus links theoretical concepts with concrete applications within the framework of Industry 4.0 and complements current trends in interdisciplinary technical training in sustainability and automation. In a laboratory, the experimental prototype represents the overall production cycle, providing a useful tool for automation practices, sustainability and performance evaluation. In addition, it can be scaled up to pilot areas or advanced technical training systems
