This final degree project focuses on the design and development of a metal piece detector device, addressing a practical problem in the tire recycling process. Currently, the implementation of modern technology in some stages of tire recycling is very limited. This study focuses on one of the first phases of the process: the conveyor belt that moves tire pieces of dimensions in the order of 10 cm. At this stage, an operator performs visual inspections to ensure that unwanted metal objects, such as screws, rivets, or small iron fragments, are not transported to the next stage, the granulator machine. This machine, equipped with rotating steel blades, can require high maintenance or replacement costs when it accidentally processes these unwanted metallic materials. The solution proposed in this report uses a combination of balanced inductive and detector coils to identify the presence of unwanted metals on the conveyor by detecting the magnetic field alteration caused by metallic elements. More specifically, the system consists of a primary inductive coil and two side detector coils, which operate according to Faraday's law of electromagnetic induction. The magnetic field from the primary coil generates eddy currents in metallic objects, which in turn generate magnetic fields that alter the flux detected by the secondary coils. Regarding the structure of our system, it features rectangular coils, specifically designed to fit the physical limitations of the conveyor belt setup. During the development of the system, various tests and analyses were conducted with the aim of optimizing the detector in the most efficient way, while also ensuring that it appropriately meets the real operational needs of the recycling plant. Finally, the results obtained met the stated objectives, making it possible to significantly reduce human error, increase operational safety, and reduce maintenance and personnel costs at tire recycling plants. Future work will focus on refining the detection algorithms and extending their use to other applications where similar risks exist.
