Abstract
- Winkelimpulsgeber wird relativ zur Rotorwelle in beliebiger Position fest montiert
- Der Rotor wird mit einem vorgegebenen Stempel visuell unter die Mitte einer Hauptdruckrolle bewegt (Grobposition)
- Der Rotor wird bis zum Auftauchen des Umfangsimpulses gedreht und die Winkelimpulse bis zum Umfangsimpuls werden von einem Maschinenrechner gezählt und ihre Anzahl wird gespeichert
- Der Rechner errechnet die in Winkelimpulsen ausgedrückten Grobpositionen aller Stempel in bezug auf den Umfangsimpuls und erzeugt bei Drehung des Rotors einen Grob-Positionsimpuls pro Stempel
- Im Rechner wird jeder Grobposition ein sich beidseitig der Grobposition erstreckendes Meßfenster zugeordnet
- Im Betrieb der Tablettenpresse wird bei jedem Winkelimpuls im Meßfenster oder über den gesamten Signalverlauf pro Stempel der Preßkraftverlauf abgetastet
- Der Rechner ermittelt die realen Stempelpositionen bei den Preßkraftmaxima oder -Minima und bestimmt die Abweichung (k) der realen Positionen von den Grobpositionen
- Der Rechner ermittelt aus den einzelnen Abweichungen einen Korrekturfaktor zur Bestimmung der Feinpositionen der Stempel.
