Prototipo de un sistema a escala de una maquina trituradora y pesadora de vidrio para reciclaje

Abstract

The objective of this project is the implementation of a prototype glass crushing and weighing machine for recycling. This system is based on a hammer mill with blades, one of the most commonly used classic models for scale prototypes, ideal for learning and understanding the functioning and design of this mechatronic system. Its main objective is to apply a conventional crushing system to prevent glass loss due to common mishandling in manual crushing processes or with very old machines. In this way, modern automated machines that perform sustainable practices could be applied, making a positive impact on global waste management both nationally and internationally. For the execution of this prototype, a start-stop system is employed. When the start button is pressed, the capacitive sensor is activated to detect the first batch of glass bottles. As they fall onto the axis where the hammer mill with blades is rotating, the bottles are crushed. After processing the first batch and when no more glass bottles are detected, the three-phase motor stops, optimizing energy use and preventing the axis from spinning without processing glass bottles. Additionally, the crushed residues pass through a sieve and rest on a scale for weighing, with the weight displayed on a laptop screen in kilograms. An emergency stop button and a buzzer have also been added to alert about potential risks or any anomalies, such as possible blockages during the process.
