DOLLAR A Bei der erfindungsgemäßen Vorrichtung sowie dem Verfahren für die Prüfung von Wertpapieren, insbesondere Banknoten, auf das Vorhandensein von Fremdmaterial, insbesondere Klebestreifen, werden zu prüfende Banknoten mit polarisiertem Licht beleuchtet, von den zu prüfenden Banknoten reflektiertes Licht wird untersucht, wobei die Menge des von den zu prüfenden Banknoten reflektierten Lichts mit einer von der Polarisierung des beleuchtenden Lichts abweichenden Polarisierung ermittelt wird, und in Abhängigkeit von der ermittelten Menge reflektierten Lichts wird auf das Vorhandensein von Fremdmaterial geschlossen.The invention relates to a device and a method for checking securities, in particular bank notes, for the presence of foreign material, in particular adhesive strips. DOLLAR A In the device according to the invention and the method for checking securities, especially banknotes, for the presence of foreign material, especially adhesive strips, banknotes to be checked are illuminated with polarized light, light reflected from the banknotes to be checked is examined, the amount of light reflected by the bank notes to be checked is determined with a polarization differing from the polarization of the illuminating light, and depending on the determined amount of reflected light, the presence of foreign material is concluded.
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren für die Prüfung von Wertpapieren, insbesondere Banknoten, auf das Vorhandensein von Fremdmaterial, insbesondere Klebestreifen.The The invention relates to an apparatus and a method for the testing of Securities, in particular banknotes, for the presence of foreign material, in particular adhesive strips.
Banknoten liegen häufig in veränderter Form vor, beispielsweise können die Banknoten Fremdmaterialien aufweisen, insbesondere Klebestreifen, die auf die Banknoten aufgeklebt sind, und die Banknoten für eine weitere Benutzung unbrauchbar machen.banknotes are common in changed Form before, for example, can the banknotes have foreign materials, in particular adhesive strips, which are stuck on the banknotes, and the banknotes for another Make use unusable.
Zur Erkennung derartig veränderter Banknoten ist bekannt, die Banknoten zu beleuchten und das von den Banknoten reflektierte Licht zu überprüfen. Bereiche der Banknoten, die Fremdmaterial wie Klebestreifen aufweisen, reflektieren in der Regel mehr Licht als Bereiche ohne derartiges Fremdmaterial, wodurch das Fremdmaterial erkannt werden kann.to Detection of such changed Banknotes are known to illuminate the banknotes and that of the Banknotes reflected light to check. areas Banknotes that have foreign material such as adhesive tape, reflect usually more light than areas without such foreign material, thereby the foreign material can be detected.
Die bekannte Erkennung des Fremdmaterials weist jedoch den Nachteil auf, daß die Erkennung des Fremdmaterials nicht für alle Fälle sichergestellt ist. Weisen die Banknoten beispielsweise Sicherheitselemente wie Hologramme oder andere Elemente auf, die Kunststoffolien und/oder metallisierte Bereiche aufweisen, kann das Vorliegen von Fremdmaterial nicht mehr ohne weiteres erkannt werden, da auch durch die Sicherheitselemente eine größere Menge Licht reflektiert wird, als von anderen Bereichen der Banknoten.The However, known recognition of the foreign material has the disadvantage on that the Detection of foreign material is not ensured in all cases. Point the banknotes for example security elements such as holograms or other elements, the plastic films and / or metallized areas exhibit, the presence of foreign material can no longer without be recognized, as well as by the security elements a bigger amount Light is reflected, as from other areas of banknotes.
Andere bekannte Vorrichtungen und Verfahren zur Erkennung von Fremdmaterial sehen eine Dickenmessung der Banknoten vor, um auf den Banknoten befindliches Fremdmaterial ermitteln zu können. Die Dickenmessung kann dabei mechanisch, optisch oder akustisch erfolgen.Other known devices and methods for detecting foreign material provide a thickness measurement of the banknotes in front of the banknotes to be able to determine foreign material. The thickness measurement can doing this mechanically, visually or acoustically.
Jedoch kommt es auch bei diesen Vorrichtungen und Verfahren zur Erkennung von Fremdmaterial zu Problemen in Bereichen der Banknoten, die Sicherheitselemente aufweisen, die auf die Banknoten aufgebracht sind. Diese Probleme entstehen dadurch, daß in diesen Bereichen bereits durch die Sicherheitselemente eine Modulation der Dicke bewirkt wird, wodurch die Erkennung der durch das Fremdmaterial verursachten Dickenänderung erschwert wird.however It also comes with these devices and methods for detection from foreign material to problems in areas of banknotes, the security elements have, which are applied to the banknotes. These problems arise from the fact that in these areas already by the security elements a modulation the thickness is effected, thereby preventing the detection by the foreign material caused thickness change is difficult.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine Vorrichtung und ein Verfahren für die Prüfung von Wertpapieren, insbesondere Banknoten, anzugeben, welche es erlauben zuverlässig festzustellen, ob die Banknoten unzulässig durch Fremdmaterial, wie aufgeklebte Klebestreifen, verändert wurden.task Therefore, it is the object of the present invention to provide a device and a procedure for the exam of securities, in particular banknotes, which allow it reliable determine whether the banknotes are inadmissible by foreign material, such as pasted adhesive strips, were changed.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung und ein Verfahren mit den Merkmalen der Ansprüche 1 bzw. 5 gelöst.These The object is achieved by a Device and a method with the features of claims 1 or 5 solved.
Bei der erfindungsgemäßen Vorrichtung und dem Verfahren für die Prüfung von Wertpapieren, insbesondere Banknoten, auf das Vorhandensein von Fremdmaterial, insbesondere Klebestreifen, werden zu prüfende Banknoten mit polarisiertem Licht beleuchtet, von den zu prüfenden Banknoten reflektiertes Licht wird untersucht, wobei die Menge des von den zu prüfenden Banknoten reflektierten Lichts mit einer von der Polarisierung des beleuchtenden Lichts abweichenden Polarisierung ermittelt wird, und in Abhängigkeit von der ermittelten Menge reflektierten Lichts wird auf das Vorhandensein von Fremdmaterial geschlossen.at the device according to the invention and the method for the exam of securities, in particular banknotes, on the presence Foreign material, in particular adhesive strips, become banknotes to be checked illuminated with polarized light, from the banknotes to be tested reflected light is examined, with the amount of that of the to be tested Banknotes reflected light with one of the polarization of the illuminating light deviating polarization is determined, and depending from the determined amount of reflected light is based on the presence closed by foreign material.
Die erfindungsgemäße Vorrichtung und das Verfahren für die Prüfung von Banknoten weisen den Vorteil auf, daß auf Banknoten aufgebrachtes Fremdmaterial, welches die Polarisation von Licht verändert, wie Kunststoffmaterial bzw. Klebestreifen, sicher erkannt werden kann. Dies ist selbst für den Fall möglich, daß sich das Fremdmaterial in Bereichen der Banknoten befindet, die Sicherheitselemente aufweisen, welche selbst Kunststoffolien und/oder metallisierte Bereiche aufweisen.The inventive device and the method for the exam of banknotes have the advantage that foreign material applied to banknotes, which changes the polarization of light, such as plastic material or adhesive strips, can be reliably detected. This is itself for the Case possible, that yourself the foreign material is located in areas of the banknotes, the security elements which have themselves plastic films and / or metallized Have areas.
