Abstract

Przedmiotem zgłoszenia są sposoby i układy sterowania kątem natarcia wrębiarki. Sterownik otrzymuje sygnał czujnika wskazujący kąt natarcia wrębiarki oraz odbiera profil docelowego kąta natarcia (610) wyznaczający wiele docelowych kątów natarcia dla różnych sekcji przodka minerału. Sterownik określa różnicę kąta natarcia między kątem natarcia a docelowym kątem natarcia wrębiarki, wyznacza poprawkę wysokościową kąta natarcia odpowiadającą nowej wysokości dla wrębnika przyspągowego wrębiarki w oparciu o różnicę kąta natarcia oraz zmienia wysokość wrębnika przyspągowego w oparciu o poprawkę wysokościową kąta natarcia.
