Abstract

Et system og en fremgangsmåte for automatisk innretting av gjengene av en ledeskrue med gjengene av en skruedrivmekanisme, hvor skruedrivmekanismen virker til å omforme rotasjonsbevegelsen av ledeskmen til lineær bevegelse for å drive ut innholdet av en montert sprøyte. Systemet omfatter en driverposisjonssensor for bestemmelse av posisjonen til skruedrivmekanismen langs ledeskmen og en prosessor for mottaking av posisjonssignaler fra driverposisjonssensoren, for bestemmelse av en påkrevet rotasjon av ledeskmen for å sørge for innretting av de to sett av gjenger, og for effektuering av den påkrevde rotasjon av ledeskmen for å oppnå denne innretting. Det er inkludert en automatisk kalibreringsmtine som sjekker etter forandringer i kalibreringen av systemet, og hvis de finnes, oppdaterer en konverteringsfaktor for å gjenopprette nøyaktighet. Forskjellige sensorer brukes til å overvåke operasjonen av komponenter.
