E-cycle: recyclable selection system

Abstract

The process of selecting recyclable materials involves identifying and classifying materials according to their characteristics and conveying them to their respective containers. To automate this process, a conveyor belt system was designed that, with the presence of sensors, directs the waste to its respective collector. The solution allows this material classification process present in fields focused on sustainability, such as recycling, to be optimized and also for the human work involved in this stage to be more inclusive. As labor is employed, it is a sys tem that is not completely independent. Considering the complete system with all interlocking subnetworks, there is a total of 22 inputs and 11 controlled outputs and the process will be modeled using the Production Flow Schema (PFS) methodology to obtain a Petri net (RdP), presented in the format of an interpreted network, associating input signals with transitions and outputs with places. The control model will be validated by verifying good RdP properties using software as a tool and the behavior of the network in terms of the states reached throughout a simulation. Ladder will be used to program the controller, with the process logic given by the vertical arrangement of rungs, obtained through the conversion of the Petri net by isomorphism. Finally, the behaviors observed in the Petri net and in the Ladder of this system were compared to assess its consistency, and the results were aligned with the expected ones.
