Method for controlling filling level of coating liquid in collecting tray under chambered squeegee of printing machine, involves automatically controlling filling level by adaptive control based on principle of model reference control
Method for controlling filling level of coating liquid in collecting tray under chambered squeegee of printing machine, involves automatically controlling filling level by adaptive control based on principle of model reference control
The method involves automatically controlling the filling level (7) by an adaptive control. The adaptive control is based on the principle of model reference control, or controlled adaptation with parallel comparison model. The aging or wear-induced change of a tube of a peristaltic pump or hose pump is compensated by the adaptive control. The viscosity difference between the different kinds or types of the coating liquid is compensated by the adaptive control. An independent claim is included for a device for controlling the filling level of a coating liquid in a collecting tray under a squeegee device or a chambered squeegee of a printing machine.
