Description
Die Erfindung betrifft eine Vorrichtung zum Antrieb linearer Lautschriftträger, wie Filmbänder o. dgl., bei welcher zur Erzielung einer konstanten Ablaufgeschwindigkeit an der Aufzeichnungs- bzw. Wiedergabestelle eine lediglich mit bremsenden Dämpfungsmitteln versehene, vom Lautschriftträger angetriebene Tonrolle und gleichförmige Zugkraft gewährleistende Spannrollen o. dgl. vorgesehen sind. Als Dämpfungsmittel verwendet man in der Regel Wirbelstrombremsen oder in einem mit Flüssigkeit, ζ. Β. ölgefüllten Behälter umlaufende Bremsflächen.The invention relates to a device for driving linear phonetic carriers, such as Film tapes or the like, in which to achieve a constant running speed the recording or playback point only with braking damping means provided sound roll driven by the phonetic carrier and uniform tensile force Ensuring tension rollers o. The like. Are provided. Used as a dampening agent one usually eddy current brakes or in one with liquid, ζ. Β. oil-filled container circumferential braking surfaces.
Gegenüber den bereits bekannten Vorrichtungen dieser Art zeichnet sich die neue Einrichtung insbesondere durch Einfachheit und zuverlässige Wirkungsweise unter Gewährleistung einer in weitgehendem Maße konstanten Ablaufgeschwindigkeit des Lautao schriftträgers an der Aufzeichnungs- bzw. Wiedergabestelle aus, was erfindungsgemäß dadurch erreicht ist, daß die zur Führung des Lautschriftträgers dienende Tonrolleaus einem feststehenden inneren Zylinder und einem über diesem unter Zwischenschaltung einer an sich bekannten, z. B. aus öl bestehenden Dämpfungsflüssigkeit drehbaren äußeren Mantel besteht.Compared to the already known devices of this type, the new device stands out especially through simplicity and reliable operation under guarantee a largely constant running speed of the Lautao script carrier at the recording or playback point from what according to the invention is achieved in that the sound roller serving to guide the phonetic carrier from a fixed inner cylinder and one above this with the interposition of a known per se, e.g. B. consisting of oil damping fluid rotatable outer Coat consists.
Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel, bei welchem der Lautschriftträger von einem Filmband gebildet wird. The drawing illustrates the invention using an exemplary embodiment in which the phonetic transcription carrier is formed by a tape of film.
Abb. ι zeigt schematisch eine Ausführungsform der Antriebsvorrichtung. Abb. 2 ist ein Schnitt durch die zur Führung des Lautschriftträgers dienende Tonrolle. Fig. Ι shows schematically an embodiment of the drive device. Fig. 2 is a section through the sound roll used to guide the phonetic carrier.
Das Filmband 1 bewegt sich über die beiden Rollen 3 und 11, von denen die Rolle 3 mit Zacken versehen ist. Vor der Zackenrolle 3 sind Leitrollen 2 angeordnet, welche eine sichere Führung des Filmbandes 1 über die Zackenrolle gewährleisten. In jeder der beiden zwischen den Rollen 3 und 11 befindliehen Filmstrecken sind in an sich bekannter Weise unter dem Einfluß von Dämpfungsmitteln stehende Spannvorrichtungen vorgesehen. Sie bestehen bei dem gezeichneten Ausführungsbeispiel aus unter der Einwirkung von Federn 5 stehenden Spannrollen 4> die Dämpfungsvorrichtungen aus an den. Lagerarmen 6 der Spannrollen 4 angeordneten Kolben 7, welche in z. B. mit öl 9 gefüllte Behälter 8 eintauchen. ' Um Geschwindigkeitsschwankungen an der durch die Linse 13 in Abb. 1 angedeuteten Aufnahmestelle bzw. an der S teuer stelle auszugleichen und gleichwohl besondere Schwungmassen zu vermeiden, besteht die Tonrolle 11 gemäß der Erfindung aus einem feststehenden inneren Zylinder 10 und einem über letzterem unter Zwischenschaltung einer an sich bekannten Dämpfungsflüssigkeit drehbaren äußeren Mantel 11. Als Dämpfungsflüssigkeit kann z. B. Öl dienen, welches einen zwischen dem Innenzylinder 10 und dem drehbaren äußeren Mantel 11 befindlichen Zwischenraum 12 ausfüllt und bei dem in Aibb. 2 mit konstruktiven Einzelheiten dargestellten Ausführungsbeispiel der Tonrolle durch die verschließbare Öffnung 14 in den Innenraum 12 eingefüllt wird.The film tape 1 moves over the two rollers 3 and 11, of which the roller 3 is serrated. In front of the tooth roller 3 guide rollers 2 are arranged, which ensure safe guidance of the film tape 1 over the zigzag roller. In each of the the two film lines located between the rollers 3 and 11 are known per se Way under the influence of damping means provided clamping devices. In the illustrated embodiment, they consist of under the action from springs 5 standing tension rollers 4> the damping devices from the. Bearing arms 6 of the tensioning rollers 4 arranged piston 7, which in z. B. filled with oil 9 Immerse container 8. 'About speed fluctuations at the recording point indicated by the lens 13 in Fig. 1 or to compensate at the expensive point and nevertheless avoid special centrifugal masses, the clay roller 11 according to the invention consists of a fixed inner one Cylinder 10 and one above the latter with the interposition of a known per se Damping fluid rotatable outer jacket 11. Can be used as damping fluid z. B. serve oil, which one between the inner cylinder 10 and the rotatable outer Sheath 11 located intermediate space 12 fills and the one in Aibb. 2 embodiment shown with structural details the clay roll is filled into the interior space 12 through the closable opening 14 will.
