Summary: | The device (1) has a control and regulating unit (4) for controlling pressure and velocity of injection screw (2). A pressure estimator (5) is provided for estimating pressure of injection screw. A load estimator (6) is provided for estimating counteracting load of injection screw. The control and regulating unit is provided to report the estimated counteracting load of injection screw. An independent claim is included for method for controlling and regulating injection screw of injection molding machine.
Steuer- und/oder Regeleinrichtung (1) zur Steuerung und/oder Regelung einer Einspritzschnecke (2) einer Spritzgießmaschine (3), zumindest umfassend eine Steuer-und/oder Regeleinheit (4) zur Steuerung und/oder Regelung des Drucks (p) und/oder der Geschwindigkeit (q) der Einspritzschnecke (2), und einen Druckschätzer (5) zum Schätzen eines Drucks (p') der Einspritzschnecke (2), wobei ein Lastschätzer (6) zum Schätzen einer der Einspritzschnecke entgegenwirkenden Last (k') vorgesehen ist, wobei durch den Lastschätzer (6) die geschätzte Last (k') zumindest an die Steuer-und/oder Regeleinheit (4) meldbar ist. |
