Description
Die Erfindung betrifft ein Gerät zur Herstellung von Lichtpausen oder ähnlichen Vervielfältigungen. Gemäß der Erfindung werden die zu belichtenden Papiere u. dgl. durch eine kontinuierliche Transportvorrichtung unmittelbar über die Unter- und Oberseite einer Leuchtstofflampenreihe hinwegbewegt. Entsprechend der Eigenschaft des kalten Bandlichtes der Leuchtstofflampen in Verbindung mit der Anordnung .des Papiertransportes können verhältnismäßig kleine Dimensionen Jies Gerätes erreicht werden.The invention relates to a device for producing blueprints or similar reproductions. According to the invention, the papers to be exposed are and the like by a continuous transport device directly over the lower and top of a row of fluorescent lamps moved away. According to the property of the cold band light of the fluorescent lamps in connection with the arrangement .des Paper transport can reach relatively small dimensions Jies device will.
Die Abbildungen zeigen ein Ausführungsschema des Erfindungsgegenstandes: Eine Montageplatte i i trägt die Fassungen i° der nebeneinanderliegenden Leuchtstofflampen i mit ihren Glimmzündern, deren Zuleitungen innerhalb der Montageplatte liegen. Um diese Leuchtstofflampen und zwei als Begrenzung dienende nicht drehbare Walzen 2 ist ein strahlendurchlässiges Band 3 gelegt, das durch eine Spannvorrichtung straff gehalten wird. Zwei U-förmige Eisenbleche auf jeder Seite der Montageplatte nehmen die Lager auf für drei drehbare Walzen, wovon eine, 6, vertikal verschiebbar ist zum Straffen des endlosen Transportbandes 9 und eine, 7, durch einen Elektromotor 8 angetrieben ist. Über diese drei Walzen 5, 6, 7 läuft das endlose, Transportband 9. Neben dem Elektromotor, dessen Drehzahl regulierbar ist und auf die Antriebswalze 7 übersetzt wird, sind die zu jeder Leuchtstofflampe gehörigen Drosselspulen mit Entstörkondensatoren io aufmontiert.The figures show an embodiment of the subject matter of the invention: A mounting plate i i carries the sockets i ° of the adjacent fluorescent lamps i with their glow starters, the leads of which are inside the mounting plate. Around these fluorescent lamps and two limiting non-rotating rollers 2, a radiolucent tape 3 is placed, which is taut by a tensioning device is held. Take two U-shaped iron sheets on each side of the mounting plate the bearings for three rotatable rollers, one of which, 6, can be moved vertically for tightening the endless conveyor belt 9 and one, 7, by an electric motor 8 is driven. The endless conveyor belt runs over these three rollers 5, 6, 7 9. Next to the electric motor, the speed of which can be regulated, and on the drive roller 7 is translated, the choke coils belonging to each fluorescent lamp are included Interference suppression capacitors installed on top.
Bei dem Arbeitsvorgang des Gerätes wird nach Einschalten des Motors und Aufleuchten aller Leuchtstofflampen die Kopiervorlage mit _dem zu belichtenden Papier zwischen das laufende, . endlose Transportband 9 und das strahlendurchlässige Band 3 gebracht. Das Transportband führt die Papiere zunächst über die Unter-, dann über die Oberseite der von dem strahlendurchlässigen Band umschlossenen Leuchtstoff lampen.During the operation of the device, after switching on the motor and all fluorescent lamps light up the master copy with the one to be exposed Paper between the running,. endless conveyor belt 9 and the radiolucent Volume 3 brought. The conveyor belt guides the papers first over the lower, then over the top of the phosphor enclosed by the radiolucent tape lamps.
Die Belichtungszeit ist regulierbar durch Drehzahleinstellung des Elektromotors und damit der Geschwindigkeit des Transportes. Sie richtet sich nach Erfahrungswerten für die verschiedenen Papiere und nach der Anzahl der Leuchtstofflampen.The exposure time can be regulated by adjusting the speed of the Electric motor and thus the speed of the transport. She conforms to Empirical values for the different papers and according to the number of fluorescent lamps.
