Filmen Beschreibung Gegenstand der Erfindung ist ein Verfahren und eine zu dessen Ausführung dienende Vorrichtung zum berührungslosen Abtasten mit Infrarot-Licht von laufenden Bändern z.B. Filmen, um mechanische Beschädigungen an denselben festzustellen, zu lokalisieren, zu registrieren oder zu zählen. Counting mechanical damage to moving belts, e.g. Films Description The invention relates to a method and a method for the same Design serving device for contactless scanning with infrared light of moving tapes, e.g. films, to determine mechanical damage to them, to locate, register or count.
Zu den mechanischen Beschädigungen, die mit Hilfe des beschriebenen Verfahrens ermittelt, aufgezeichnet oder gezählt werden können, gehören: Perforationsschäden, Längs-, Quer- und Schrägschrammen, durch die Zähne der Transportrollen beschädigte, geräderte, sowie stark deformierte Bilnder/Filme.To the mechanical damage that is described with the help of the Procedures that can be determined, recorded or counted include: perforation damage, Longitudinal, cross and diagonal scratches damaged by the teeth of the transport rollers, whacked, as well as badly deformed pictures / films.
Filme zum Beispiel sind bei der Bearbeitung und bei der Projektion stets der Gefahr ausgesetzt, durch mechanische Einflüsse so stark beschädigt zu werden, daß eine Weiterverarbeitung oder Weiterverwendung ausgeschlossen ist. Um derartige Schäden zu erkennen, sind dem Anmelder zur Zeit drei Verfahren bekannt.Films, for example, are in the process of being edited and projected always exposed to the risk of being so badly damaged by mechanical influences that further processing or further use is excluded. Around To detect such damage, the applicant is currently aware of three methods.
Die visuelle Kontrolle, Nachteile: sie ist zeitaufwendig und das Protokoll über den mechanischen Zustand des Films subjektiv.The visual control, disadvantages: it is time consuming and the protocol subjective about the mechanical condition of the film.
Die mechanische Abtastung des Films mittels saphirbestückter Fühler, Nachteile: durch die mechanische Abtastung ist die Gefahr einer zusätzlichen Beschädigung groß. Über die Art der Zählung oder Registrierung der Beschädigungen liegen dem Anmelder keine Erkenntnisse vor.The mechanical scanning of the film by means of sapphire-tipped sensors, Disadvantages: the mechanical scanning creates the risk of additional damage great.

Die berührungslose Abtastung mit Hilfe eines optischen Systems, welches den Film, mechanisch angetrieben, zeilenförmig abtastet. Beschrieben in nBild und Ton, Heft 7/1975 VEB Fotokinoverlag Leipzig, DDR WP 86 512.The contactless scanning with the help of an optical system, which the film, mechanically driven, scans in lines. Described in picture and Ton, issue 7/1975 VEB Fotokinoverlag Leipzig, GDR WP 86 512.
Nachteile: Aufwendige Mechanik. Der Inhalt des fotografischen Bildes auf dem Film verfälscht das Meßergebnis, geringe Durchlaufgeschwindigkeit des zu kontrollierenden Filmmaterials. Es wird mit elektromechanischen Zählern nur die Anzahl der Beschädigungen erfaßt, nicht aber ihre Position auf dem Film.Disadvantages: complex mechanics. The content of the photographic image on the film falsifies the measurement result, low throughput speed of the too controlling Footage. With electromechanical counters it is only the number of damages captured, but not their position on the film.
Der Erfindung liegt die Aufgabe zugrunde, die vorgenannten Nachteile zu vermeiden, durch berührungslose Abtastung den zu kontrollierenden Film zu schonen und mittels eines an die Vorrichtung angeschlossenen Linienschreibers ein Protokoll zu erstellen, welches jederzeit reproduzierbar ist. Ferner gestattet es, die Lage der Beschädigung in vertikaler sowie ihre Ausdehnung in horizontaler Richtung abzulesen. Dazu kommt ein schnellerer Durchlauf des zu kontrollierenden Films, als bei den bisher bekannten Methoden sowie durch Vergleich der aufgezeichneten Diagramme, die Erkenntnis über neu hinzugekommene Beschädigungen.The invention is based on the aforementioned disadvantages to avoid sparing the film to be checked through contactless scanning and a log by means of a line recorder connected to the device to create, which can be reproduced at any time. It also allows the location the damage in the vertical direction and its extent in the horizontal direction. In addition, the film to be checked runs faster than with the previously known methods as well as by comparing the recorded diagrams that Knowledge of newly added damage.
Das Verfahren nach der Erfindung beruht darauf, daß mehrere, von der einschlägigen Industrie hergestellte Reflexionsfühler 1 (Reflective Objekt Sensor) über- oder versetzt nebeneinander angebracht werden. Der durch Zahnrollen 2 angetriebene und an den Rändern über Gleitschienen 3 geführte Film wird in einem definierten Abstand, vor einem mattschwarzen Schirm 4 kontinuierlich an den Reflektionsfühlern vorbeigeführt. Ein vor diesen befestigtes, mit Durchbrüchen für den Strahlengang versehenes Stahlblech, schützt die Vorderseite des Reflexionsfüblers vor Beschädigungen beim Einlegen des Films. Der Reflexionsfühler besteht aus einer Leuchtdiode, die zusammen mit einem Fototransistor in einem gemeinsamen Gehäuse untergebracht ist. Ein-und Austrittsöffnung sind mit einem infrarot-durchlässigen Filter abgedeckt, so daß weder die Raumbeleuchtung noch der Inhalt des fotografischen Bildes auf dem Film einen Einfluß auf das Ergebnis der Messung haben. Da der unbeschädigte Film ein anderes Reflexionsvermögen hat als der beschädigte, entsteht am Ausgang des Reflexionsfühlers eine Spannungsdifferenz. Nach erfolgter Verstärkung wird das Signal der Anordnung der Reflexionsfühler entsprechend den Kanälen eines Vielbereichsschreibers zugeführt. Der Papiervorschub wird im Idealfall vom Antrieb der Umrollvorrichtung mitangetrieben, so daß die Durchlaufgeschwindigkeit des Films zum Papiervorschub proportional ist. Bei Schreibern mit eingebautem Antrieb ist dieser mit dem Schalter der Umrollvorrichtung zu koppeln. Auf diese Weise ist es möglich, die Lage der Beschädigung in der Vertikalen sowie ihre Ausdehnung in der Horizontalen genau zu lokalisieren.The method according to the invention is based on the fact that several of the Relevant industry-made reflection sensor 1 (reflective object sensor) be mounted one above the other or offset next to one another. The driven by toothed rollers 2 and at the edges over slide rails 3 guided film is in a defined Distance, in front of a matt black screen 4, continuously on the reflection sensors passed by. One attached in front of these, with openings for the beam path steel sheet, protects the front of the reflective filler from damage when loading the film. The reflection sensor consists of a light-emitting diode that is housed together with a phototransistor in a common housing. Inlet and outlet openings are covered with an infrared-permeable filter, so that neither the room lighting nor the content of the photographic image on the Film have an influence on the result of the measurement. Because the undamaged film has a different reflectivity than the damaged one, arises at the exit of the Reflection sensor a voltage difference. Once amplified, the signal becomes the arrangement of the reflection sensors according to the channels of a multi-range recorder fed. Ideally, the paper feed is provided by the drive of the rewinding device driven so that the speed of the film to advance the paper is proportional. In the case of recorders with a built-in drive, this is with the switch to couple the rewinding device. In this way it is possible to locate the damage precisely to localize in the vertical as well as their extent in the horizontal.
Die Tatsache, daß mechanische Beschädigungen an Bändern/Filmen in horizontaler Richtung stets eine Ausdehnung von mehreren Längeneinheiten haben, erlaubt die Konstruktion einer vereinfachten Ausführung mit einkanaligem Linienschreiber. Ein zusätzlich angebrachter Reflexionsfühler tastet die Perforation des vorbeilaufenden films ab. Die so erhaltenen und aufbe reiteten Impulse dienen zur Steuerung eines elektronischen Umschalters.The fact that mechanical damage to tapes / films in always have an extension of several units of length in the horizontal direction, allows the construction of a simplified version with a single-channel line recorder. An additionally attached reflection sensor scans the perforation of the passing film. The pulses thus obtained and prepared are used to control an electronic switch.
Dieser legt in vorwählbaren Zeitabständen die Ausgänge der den Film abtastenden Reflexionsfübler nacheinander an den Eingang des Linienschreibers. Die von den einzelnen Reflexionsfühlern abgegebene Information ist einer Gleichspannung unterschiedlicher Höhe überlagert, so daß die Lage und die Ausdehnung der Beschädigung am Registrierstreifen einwandfrei erkennbar wiedergegeben werden.This sets the outputs of the film at preselectable time intervals scanning reflection filler one after the other to the input of the recorder. the The information given by the individual reflection sensors is a direct voltage different heights superimposed, so that the location and extent of the damage can be clearly reproduced on the registration strip.
Als weiteres läßt sich mit einer Kombination von Abtastvorrichtung und Digitalzähler die Summe der Beschädigungen pro Längeneinheit erfassen.As a further can with a combination of scanning device and digital counters record the sum of the damage per unit of length.
Der so erhaltene Zahlenwert erlaubt eine Aussage über die mechanische Qualität des Films.The numerical value obtained in this way allows a statement to be made about the mechanical Quality of the film.
Eine Anordnung mehrerer übereinander montierter ReflexionsfÜhler, in Verbindung mit einem Verstärker, einem Relais und einem Summer können als Warneinrichtung dienen. An mehreren Stellen im Filmlauf einer Filmentwicklungsmaschine, oder, da durch die im Infrarotgebiet liegende Strahlung der Reflexionsfühler keine Belichtung des Rohfilms eintritt, auch an Kopiermaschinen installiert, bietet die Vorrichtung Schutz. Sie warnt beim Vorbeilauf beschädigter Filme, so daß die Maschine stillgesetzt und der Fehler behoben werden kann, bevor größere Mengen Filmmaterials beschädigt wurden.An arrangement of several reflection sensors mounted on top of each other, in connection with an amplifier, a relay and a buzzer can act as a warning device to serve. At several points in the film run of a film developing machine, or there No exposure due to the radiation from the reflection sensor in the infrared area of the raw film, also installed on copying machines, is provided by the device Protection. It warns when damaged films are passing, so that the machine is shut down and the error can be corrected before large amounts of footage are damaged became.
