Description
Die Erfindung betrifft ein Verfahren zur Überprüfung des Zustands einer Vorrichtung zur Prüfung von Blattgut, die wenigstens eine Beleuchtungseinrichtung, ein lichtdurchlässiges Meßfenster und einen Detektor aufweist.The invention relates to a method for checking the state of a Device for testing sheet material, the at least one lighting device, has a translucent measuring window and a detector.
Eine Vorrichtung der oben genannten Art ist z.B. aus der WO98/26276 bekannt. Das von einer Beleuchtungseinrichtung emittierte Licht trifft durch ein lichtdurchlässiges Meßfenster auf das zu prüfende Blattgut auf. Das vom Blattgut remittierte Licht wird dann detektiert und ausgewertet.A device of the type mentioned above is e.g. known from WO98 / 26276. The light emitted by a lighting device passes through a translucent measuring window on the sheet material to be tested. That from Light reflected from the sheet is then detected and evaluated.
Bei der bekannten Prüfvorrichtung für Blattgut besteht das Problem, daß das Meßfenster während des Betriebs verschmutzen kann. Wenn das Meßfenster verschmutzt ist, gelangt z.B. weniger Licht der Bestrahlungseinrichtung zum zu prüfenden Blattgut, wodurch das Meßsignal sinkt. Bei der Prüfung des Blattguts kann jedoch nicht festgestellt werden, ob das schwächere Meßsignal auf eine Verschmutzung des Meßfensters oder auf den Zustand des zu prüfenden Blattguts zurückzuführen ist. Dies hat zur Folge, daß es aufgrund der Verschmutzung des Meßfensters zu einer Fehlbeurteilung des zu prüfenden Blattguts kommen kann. Dadurch wird die Zuverlässigkeit bei der Prüfung von Blattgut beeinträchtigt.In the known testing device for sheet material, there is the problem that Measuring window can become dirty during operation. If the measurement window is dirty, e.g. less light from the irradiation device for sheet material to be tested, whereby the measurement signal drops. When examining the However, sheet material cannot be determined whether the weaker measurement signal to contamination of the measuring window or to the condition of the inspecting leaf material. As a result, it is due to the soiling of the measuring window leads to a misjudgment of the test item Leaf crops can come. This will increase the reliability of the Inspection of sheet material impaired.
GB-A-2 109 923 offenbart eine sellsttätige Änderung der elektronischen Verstärkung in einem Banknotenprüfgerät bei Verschmutzung des Geräts.GB-A-2 109 923 discloses an active one Change of electronic amplification in one Banknote checker if the device is dirty.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Überprüfung des Zustandes einer Prüfvorrichtung für Blattgut vorzuschlagen, die mit geringem technischem Aufwand die Feststellung von die Messung beeinträchtigenden Verschmutzungen bei einem Meßfenster der Prüfvorrichtung ermöglicht. Erfindungsgemäß wird die Aufgabe durch die in den unabhängigen Ansprüchen angegebenen Merkmale gelöst. The invention has for its object a method and a device for checking the condition of a testing device for sheet material to propose the finding of with little technical effort contamination affecting the measurement in a measurement window the test device allows. According to the invention the task is accomplished by solved the features specified in the independent claims.
Erfindungsgemäß wird zur Feststellung von Verschmutzungen bei einem Meßfenster dieses von einer Beleuchtungseinrichtung mit UV-Licht bestrahlt, wobei das durch das Meßfenster transmittierte UV-Licht von einem UV-Filter derart gefiltert wird, daß nur ein geringer Anteil den Filter passiert und zu einem Detektor durchgelassen wird. Dieser durch den Filter transmittierte Anteil des UV-Lichts wird detektiert und zur Bestimmung des Verschmutzungsgrades des Meßfensters ausgewertet.According to the invention for the detection of contamination in a Measurement window irradiated with UV light by an illumination device, the UV light transmitted through the measurement window from a UV filter is filtered so that only a small proportion passes the filter and is passed to a detector. This transmitted through the filter The proportion of UV light is detected and used to determine the degree of contamination of the measurement window evaluated.
Vorzugsweise erfolgt die Auswertung derart, daß für ein sauberes Meßfenster ein Beleuchtungsprofil aufgenommen und gespeichert wird, das mit dem jeweils aktuell aus dem detektierten Signal erhaltenen Beleuchtungsprofil verglichen wird. Anhand der Abweichung des aktuell aufgenommenen Beleuchtungsprofils von dem gespeicherten Beleuchtungsprofil kann der Verschmutzungsgrad des Meßfensters bestimmt werden. Anstelle von Beleuchtungsprofilen können jedoch auch die integrierten Meßwerte miteinander verglichen werden. In beiden Fällen weist eine Abweichung auf eine Verschmutzung des Meßfensters hin.The evaluation is preferably carried out in such a way that for a clean measurement window a lighting profile is recorded and saved, which with the illumination profile currently obtained from the detected signal is compared. Based on the deviation of the currently recorded Lighting profile from the saved lighting profile can the degree of contamination of the measuring window can be determined. Instead of However, lighting profiles can also integrate the measured values with each other be compared. In both cases, a deviation points to one Contamination of the measuring window.
Zur Bestimmung des Verschmutzungsgrades wird vorzugsweise die Empfindlichkeit des Detektors beispielsweise durch eine Verlängerung der Integrationszeit oder auch die Leuchtintensität der Beleuchtungseinrichtung oder auch die Signalverstärkung gegenüber dem normalen Betrieb bei der Prüfung des Blattguts erhöht. Weitere Vorteile sowie Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie der nachfolgenden Beschreibung und Ausführungsbeispielen der Erfindung anhand der beigefügten Figuren. The sensitivity is preferably used to determine the degree of contamination of the detector, for example, by extending the integration time or also the light intensity of the lighting device or also the signal amplification compared to normal operation at the Check of sheet material increased. Further advantages as well as further training of the Invention result from the dependent claims and the following Description and embodiments of the invention based on the attached figures.

Figur 1 zeigt beispielhaft in schematischer Darstellung das Funktionsprinzip
zur Feststellung von Verschmutzungen bei einem Meßfenster. Das Meßfenster
2 wird hierbei von einer Beleuchtungseinrichtung z.B. von zwei UV-Lampen
1 mit UV-Licht 5 bestrahlt. Das durch das Meßfenster transmittierte
UV-Licht 5 wird mittels eines UV-Filters 3 derart gefiltert, daß nur ein geringer
Anteil 6 des UV-Lichts 5 zu einem Detektor 4 gelangt. Nur dieser Anteil
des UV-Lichts wird detektiert und zur Bestimmung des Verschmutzungsgrades
des Meßfensters ausgewertet. Dabei wird der aktuelle Meßwert mit
einem gespeicherten Referenzwert verglichen, der bei einem sauberen Meßfenster
erhalten wird. Der Vergleich kann hierbei anhand der integrierten
Meßwerte oder auch anhand der aufgenommenen Beleuchtungsprofile in
bestimmten Zyklen, die von der Betriebsdauer abhängen, erfolgen. Da der
Auswertung nur der UV-Lichtanteil 6, der den Filter 3 passiert, zugrundegelegt
wird und dieser Anteil im Vergleich zu dem von der Beleuchtungseinrichtung
abgestrahlten UV-Licht 5 gering ist, der beispielsweise nur einige
Prozent beträgt, wird vorzugsweise die Empfindlichkeit des Detektors beispielsweise
durch eine Verlängerung der Integrationszeit oder auch die
Leuchtintensität der Beleuchtungseinrichtung oder auch die Signalverstärkung
zur Überprüfung des Zustands des Meßfensters gegenüber dem Betrieb
bei der Prüfung des Blattguts erhöht, wodurch die Auswertung erleichtert
und verbessert wird. Figure 1 shows an example of the principle of operation in a schematic representation
for the detection of contamination in a measuring window. The
Figur 2 zeigt eine Vorrichtung zur Überprüfung von Blattgut, insbesondere
von Banknoten, bei der beispielsweise zwei Meßfenster 2 vorgesehen sind,
die in einem Abstand gegenüber angeordnet sind. Jedem Meßfenster ist
hierbei eine Beleuchtungseinrichtung 1, z.B. in Form zweier UV-Lampen 1
zugeordnet. Die zwischen den Meßfenstern 2 transportierte und hier nicht
dargestellte Banknote wird z.B. bei der Echtheitsprüfung beidseitig mit UV-Licht
angeregt, wobei das auf jeder Seite von der Banknote remittierte Licht
von jeweils einem Detekor 4 erfaßt wird. Beispielsweise emittieren Banknoten
bei Anregung durch UV-Licht, Licht im sichtbaren Wellenlängenbereich,
was unter anderem ein Kriterium für die Echtheit der Banknoten darstellt.
Vor den Detektoren 4 ist jeweils ein UV-Filter 3 angeordnet, durch den das
Meßsignal der Banknote jedoch nicht beeinträchtigt wird, da von den Filtern
3 das von der Banknote im sichtbaren Wellenlängenbereich remittierte Licht
durchgelassen wird. Die Überprüfung des Zustands der Meßfenster erfolgt
vorzugsweise durch beidseitige Bestrahlung der Meßfenster 2 mittels des
von den Beleuchtungseinrichtungen 1 jeweils abgestrahlten UV-Lichts 5. Das
durch die Meßfenster 2 transmittierte UV-Licht 5 wird hierbei von den Filtern
3 derart gefiltert, daß nur ein geringer Anteil 6, der beispielsweise einige
Prozent beträgt, zu den Detektoren 4 durchgelassen wird. Der durch die Filter
3 transmittierte Anteil 6 des UV-Lichts 5 wird detektiert und zur Bestimmung
des Verschmutzungsgrades der Meßfenster ausgewertet. Zur Überprüfung
des Zustandes der Meßfenster 2 können diese auch nur von einer
Seite mit UV-Licht bestrahlt werden, wie dies bereits im Zusammenhang mit
Figur 1 beschrieben worden ist.Figure 2 shows a device for checking sheet material, in particular
banknotes in which, for example, two measuring
