Abstract

Ovaj rad opisuje postupak recikliranja otpadnog materijala i položaj shredder-a u njemu. Prikazana je metoda upravljanja brzinom vrtnje shredder motora te sigurnosne mjere koje su poduzete za osiguravanje sigurnog rada osoblja u blizini stroja. Pomoću PLC-a komuniciramo s frekvencijskim regulatorom te mu šaljemo informacije za paljenje/gašenje motora i željenu brzinu, a od njega dobivamo trenutnu brzinu očitanu iz senzora. Drugi dio rada se je sastojao od izrade samog softvera u ljestvičastom dijagramu te njegovim povezivanjem s HMI uređajem koji služi za vizualizaciju. Operater preko grafičkog sučelja može upravljati i nadgledati kompletan sustav, od brzine motora do svih alarma te mijenjati načine rada.<br />This paper describes the process of recycling and the purpose of the shredder in it. The motor speed control method is show together with all the safety precautions and systems that ensure workers can safely operate in the machines' vicinity. With help from a PLC, we established a communication with the frequency regulator to which start/stop commands are sent, together with the desired speed and in return we get the actual motor speed acquired from a sensor. The second part of this paper consisted of creating the automation software and connecting it to an HMI device used for visualization. Through the graphical interface, the operator can control and monitor the entire system and change the operating modes
