Abstract

Diplomski rad istražuje mogućnosti sinkronog upravljanja sa servomotorima pomoću PLC-a. Sinkronizacija i ispitivanja su rađena na Flow pack stroju, točnije na eksperimentalnom postavu koji simulira njegov rad. Flow pack je stroj za pakiranje proizvoda, koji na principu protočnog umatanja i pakira proizvode u polipropilensku foliju. Proizvodi koji se ovako pakiraju nemaju uvjet oblika, ali imaju uvjete na dimenzije. Napravljeni eksperimentalni postav simulira rad pravog stroja i ovdje su proizvodi predstavljeni jednodimenzionalno s nacrtanom linijom na pokretnoj papirnoj traci. U radu su korištena tri motora, dok pravi Flow pack može koristiti i više. Sinkronizacija je napravljena tako da jedan od motora 'vodi' druga dva. Preciznije rečeno, na temelju položaja i brzine vodećeg motora, određuju se pozicije i brzine druga dva. U prvom poglavlju je kratak uvod u automatizaciju i temu rada. Drugo poglavlje daje pregled korištene opreme za izradu eksperimentalnog postava. U trećem su obrađeni tipovi komunikacije među komponentama sustava, dok je u četvrtom navedena sva korištena programska podrška i opisan je rad programa. Peto poglavlje opisuje konceptualno rješenje problema zajedno s matematičkom podlogom koja omogućuje rad istog, uz to prikazani su i komentirani dobiveni rezultati. Šesto poglavlje daje pregled grafičkog upravljačkog sučelja s kojim operater zadaje predefinirane parametre upravljanja, pokreće i zaustavlja sustav.

Abstract (english)

This master thesis explores possibilities of synchronous control of servomotors using PLC. For that purpose experimental setup/model was made, which simulates Flow pack machine. Flow pack is a machine which uses flow wrapping to package products. Flow wrapping is process in which product of any shape is wrapped in polypropylene film. Made model of flow pack uses paper strip on which line is drawn that represents the product. Three servomotors used in this setup, of which one is a lead motor. Based on its positioning and speed, positions and speeds of other two are calculated and set. First chapter gives a brief introduction into automation and theme of this thesis. Second chapter describes equipment used in making of the model. Communication types are described in third chapter, while fourth one gives an overview of used software and elaborates how the program functions. Next is the fifth chapter, in which are given mathematical equations and conceptual solution for system control along with test results. Sixth chapter is an overview of graphical user interface. Through which operator can set control parameters, initiate or stop the system.
