Description

Die Erfindung bezieht sich auf Seil- und Bandförderungseinrichtungerimit angetriebener Auf- und Abwickeltrommel und für gleichbleibende Auf- bzw. Abwickelgeschwindigkeit; wie sie insbesondere bei Filmsprechmaschinen, Stahlton- und Magnetton-Apparaten gefordert werden muß. Es i§t bereits eine derartige Einrichtung bekannt, die ein gleichmäßig angetriebenes Friktionstreibrad enthält, das ein Magnettonband mit gleichbleibender Geschwindigkeit fördert und gleichzeitig sich gegen das Magnettonband auf der Auf- und Abwickeltrommel legt, die beide frei beweglich sind und durch Druckrollen gegen das Friktionstreibrad gedrückt und von ihm angetrieben werden (vergl. DRP 702345). Diese Einrichtung und die weiteren Einrichtungen älinlicher Art, die in der genannten deutschen Patentschrift als bekannt bezeichnet werden, sind mechanisch schwer herstellbar.The invention relates to rope and belt conveyor devices driven winding and unwinding drum and for constant winding and unwinding speed; as they are especially in the case of film speaking machines, steel sound and magnetic sound devices must be required. Such a device is already known, which is a evenly driven friction drive wheel, which contains a magnetic tape with constant Promotes speed and at the same time rushes against the magnetic tape on the and unwinding drum sets, both of which are freely movable and opposed by pressure rollers the friction drive wheel are pressed and driven by it (see DRP 702345). This facility and the other facilities of the same type mentioned in the above German patent are referred to as known, are mechanically difficult to manufacture.

Eine praktisch elegante und zugleich billige Lösung stellt demgegenüber die Erfindung dar und ist außerdem universeller verwendbar.On the other hand, there is a practically elegant and at the same time cheap solution represents the invention and is also more universally applicable.

Die Seil- und Bandförderungseinrichtung nach der Erfindung ist so gestaltet, daß zwei mit gleicher Drehzahl angetriebene gleich große Reibräder gleichzeitig die Auf- und Abwickeltrommel an deren großer freier Außenfläche antreiben und die Achsen der Reibräder und Trommeln aufeinander senkrecht stehen, daß ferner die Trommeln mit ihren Achsen in Richtung der Reibräderachsen verschiebbar angeordnet sind, daß sich unter der Wirkung eines auf die Trommelachsen ausgeübten Zuges oder Druckes das auf- bzw. ablaufende Seil oder Band (Draht oder Film) auf den Trommeln gegen ortsfest angebrachte Rollen legt und daß die Reibräder in einem solchen radialen Abstand von den Trommelachsen an den Trommelaußenflächen angreifen, in dem sich jeweilig die ortsfesten Rollen von den Trommelachsen befinden.The rope and belt conveyor according to the invention is like this designed that two friction wheels of the same size driven at the same speed simultaneously drive the winding and unwinding drum on their large free outer surface and the Axes of the friction wheels and drums are perpendicular to each other, so that the drums are arranged displaceably with their axes in the direction of the friction wheel axes that under the effect of a pull or pressure exerted on the drum axles against the running rope or tape (wire or film) on the drums fixedly attached rollers and that the friction wheels in such a radial Attack the distance from the drum axes on the outer drum surfaces, in which respectively the stationary rollers are located on the drum axles.

Die neue Einrichtung läßt sich wie erwähnt unter anderem auch für Filmsprechmaschinen verwenden. Ein Ausführungsbeispiel für diese Verwendungsart zeigen die Abb. i und 2 in Aufsicht bzw. Seitenansicht. Darin bedeuten i und 2 die Auf- und Abwickeltrommel, 3 die Druckfederlagerung der Trommeln, die den Tonfilm 4 auf den Trommeln gegen die ortsfesten Andruckrollen 5 gepreßt hält, 6 den Antriebsmotor für die beiden Reibräder 7 und das Kegelräderpaar 8 und 9, von dem das Kegelrad 9 mit der Reibrolle io gekuppelt ist, die den Film 4 über die Leitrolle i i an der Tonlampe 12 und der Photozelle 13 vorbeizieht, 14 die Führungs- und Beruhigungsrollen. Die Wirkungsweise. der in den Abbildungen gezeigten Filmförderungseinrichtung ist derart, daß beim Ablauf des Films von der Filmvorratstrommel i die Druckfedern 3 die Trommel immer weiter nach links verschieben, indem sie diese dauernd gegen die Druckrolle 5 gepreßt halten. Dadurch greift das an der gleichen Stelle bleibende Reibrad 7 an einem immer kleiner werdenden Radius an der Außenwand der Trommel i an und versetzt sie in stetig größer werdende Umlaufgeschwindigkeit. Das Umgekehrte ist der Fall bei der Auf wickeltrommel2, bei der der Filmwickel immer stärker wird, wodurch die Trommel nach links rückt, das ortsfeste Reibrad 7 an einem immer größer werdenden Trommelradius angreift und damit die Umlaufgeschwindigkeit dieser Trommel stetig abnimmt. Die Filmgeschwindigkeit zwischen den beiden Trommeln i und 2 bleibt dadurch konstant. Zur Regulierung, Beruhigung und besseren Filmführung ist noch ein Triebwerk an der Tonlampenapparatur eingefügt, das aus einem Kegelräderpaar 8 und 9, der Mitnehmerreibrolle io, der Umlenkrolle i i und den Andrucktollen 14 besteht.As mentioned, the new facility can also be used for Use movie speaking machines. An embodiment for this type of use Fig. i and 2 show in plan and side view. Here i and 2 mean the Winding and unwinding drum, 3 the compression spring mounting of the drums that hold the sound film 4 on the drums pressed against the stationary pressure rollers 5, 6 holds the drive motor for the two friction gears 7 and the pair of bevel gears 8 and 9, of which the bevel gear 9 is coupled to the friction roller io, which the film 4 on the guide roller i i on the Sound lamp 12 and the photocell 13 passes, 14 the guide and calming roles. The mode of action. of the film conveyor shown in the figures such that when the film runs off the film supply drum i, the compression springs 3 move the drum further and further to the left by constantly pushing it against the Keep pressure roller 5 pressed. As a result, what remains in the same place takes effect Friction wheel 7 at an increasingly smaller radius on the outer wall of the drum i and puts them in a steadily increasing speed of rotation. The reverse is the case with the winding drum2, where the film roll is getting stronger and stronger, whereby the drum moves to the left, the stationary friction wheel 7 on one getting bigger attacking the drum radius and thus the speed of rotation of this drum steadily decreases. The film speed between the two drums i and 2 remains thereby constant. To regulate, calm down and better film guidance is still an engine was added to the sound lamp apparatus, consisting of a pair of bevel gears 8 and 9, the driver friction roller io, the deflection roller i i and the pressure rollers 14 consists.

Durch einfaches Umsteuern der Drehrichtung des Motors 6 kann mit eventuell mehrfach erhöhter Geschwindigkeit das Zurückspulen des Films von Trommel 2 auf Trommel i vor sich gehen.By simply reversing the direction of rotation of the motor 6, with possibly rewinding the film from drum 2 to drum at several times higher speeds i go on.

Außer für Filmsprechmaschinen läßt sich die Erfindung ohne weiteres auch bei Stahldraht- und Magnetton-Apparaten verwenden. Außerdem ist die Einrichtung nach der Erfindung bei allem mit gleichmäßiger Geschwindigkeit ab- und wieder aufwickelbarem, insbesondere empfindlichem Gut, wie Textilfäden und -bändern, Gummifäden und -bändern, Kunstfasern, feinsten Drähten usw., anwendbar.Except for movie speaking machines, the invention can be used without further ado also use with steel wire and magnetic sound devices. Besides, the facility is according to the invention for everything that can be unwound and rewound again at a constant speed, especially sensitive goods, such as textile threads and ribbons, rubber threads and ribbons, Synthetic fibers, the finest wires, etc., can be used.
