Patent Abstracts of Japan JP 58-158512 A beschreibt ein Verfahren zur Messung der Dicke eines Films. Bei diesem Verfahren wird per Ultraschallwellen-Laufzeitdifferenz-Messung zuerst die Gesamtdicke des Films zuzüglich eines Trägermaterials bestimmt und danach von der Gesamtdicke die Dicke des Trägermaterials subtrahiert.patent Abstracts of Japan JP 58-158512 A describes a method of measurement the thickness of a film. In this method is by ultrasonic wave transit time difference measurement first determines the total thickness of the film plus a support material and then subtracting the thickness of the substrate from the total thickness.

Ausgehend vom skizzierten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Beschichtungsdicke eines auf einem Beschichtungsträger aufzutragenden Mediums nebenwirkungsfrei zu ermitteln.outgoing from the outlined prior art, the invention is the task underlying the coating thickness of a to be applied to a coating carrier Determine medium without side effects.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 und durch eine Vorrichtung mit den Merkmalen des Anspruchs 11 gelöst.According to the invention Task by a method having the features of claim 1 and solved by a device having the features of claim 11.
Die mit dieser Lösung erzielbaren Vorteile liegen zum einen darin, dass die Einflüsse unterschiedlicher Beschichtungsträger auf die Messung nunmehr eliminiert sind. Die Messung erfolgt innerhalb der Veredelungseinheit, so dass kurze Signallaufzeiten erzielbar sind und schnell korrekte Messergebnisse verfügbar sind. Die unterschiedlichen Laufzeiten der Reflexionssignale erlauben zum anderen eine von der Lage der Auftragswalze unabhängige Messung.The with this solution achievable advantages are, on the one hand, that the influences of different coating substrates now eliminated on the measurement. The measurement is done within the refining unit, so that short signal propagation times can be achieved are and quickly correct measurement results are available. The different ones Maturities of the reflection signals on the other hand allow one of the Position of the applicator roller independent measurement.
In weiteren, den der Erfindung zugrunde liegenden Gedanken weiterführenden Ausgestaltungen ist vorgesehen, einer Auftragswalze in der Veredelungseinheit eine Messeinheit zuzuordnen. Die Messeinheit kann derart gestaltet sein, dass sie sowohl ein Ausgangssignal emittiert, als auch dessen Reflexionssignale empfängt. Vorzugsweise handelt es sich beim Ausgangssignal um ein Ultraschallsignal. Eine andere Konfiguration der Messeinheit ist derart ausgestaltbar, dass diese aus voneinander getrenntem Sende- und Empfangsmodul besteht, welche beispielsweise winklig zueinander versetzt angeordnet sein können. Dies bietet sich beispielsweise zu Kalibrierzwecken an. Die Trennung der Messeinheit in unterschiedliche Module erlaubt außerdem eine leichte Austauschbarkeit dieser Komponenten.In further, continue the invention of the underlying idea Embodiments is provided, an applicator roll in the finishing unit to assign a measuring unit. The measuring unit can be designed in this way be that it emits both an output signal, as well as its reflection signals receives. Preferably, the output signal is an ultrasonic signal. Another configuration of the measuring unit can be configured in such a way that that this consists of a separate transmission and reception module, which, for example, be arranged at an angle to each other offset can. This is useful, for example, for calibration purposes. The separation The measuring unit in different modules also allows one easy interchangeability of these components.
Aus der Differenz der Laufzeiten beider Reflexionssignale ist die Schichtdicke des Mediums bestimmbar, welches mit dem Ausgangssignal beaufschlagt wurde. Anhand einer Zeichnung wird die Erfindung nun detaillierter beschrieben.Out the difference of the transit times of both reflection signals is the layer thickness of the medium can be determined, which acts on the output signal has been. With reference to a drawing, the invention will now be more detailed described.
