Abstract

A two roller transport mechanism is for sheet paper and is for use in such equipment as copiers. The exact slit size between the rollers is precisely adjusted. The rollers are equipped with an elastic outer on a central shaft. The elasticised outer portion of the rollers is contained between end plates of the same dia. as the elasticised section. The end plates are connected to the central shaft and serve to preserve the shape and dia. of the elasticised cover and maintain the accuracy of the slit size between the pair of rollers.

Description

Walzen für den BlattransportRollers for sheet transport

Die Erfindung betrifft die Ausbildung von Walzen für den Blattransport, wo die genaue Einstellung eines Spaltmaßes zwischen zwei Walzen eines Walzenpaares oder einer Walze und einer anderen Fläche erforderlich ist, und findet vorzugsweise bei Kopiergeräten Verwendung, Beim Blattransport in Kopiergeräten mittels Walzen ist eine griffige Oberfläche jeder dieser Walzen erforderlich, die einen durchgehenden Belag aus Gummi oder ähnlichen Material bedingt. Das gestattet jedoch keine einfache Justierung des Walzenspaltes mittels Fühllehren zwischen den Walzen, da die Nachgiebigkeit des Gummis bei Auflage auf den Fühllehren zu hohe Ungenauigkeiten mit sich bringt und das erforderliche Spaltmaß nicht eingehalten werden kann. So hat man für derartige bekannte Geräte ( z. B.The invention relates to the formation of rollers for sheet transport, where the exact setting of a gap between two rollers of a roller pair or a roller and some other surface is required, and preferably takes place in copier use, when sheet transport in copier by means of rollers a non-slip surface is required for each of these rollers, which have a continuous Cover made of rubber or similar material is conditional. However, this does not permit a simple one Adjustment of the roller gap by means of feeler gauges between the rollers, since the flexibility of the rubber when it rests on the feeler gauges leads to excessive inaccuracies and the required gap cannot be maintained. So one has for such known devices (e.g.

PENTAKTA K 100 ) spezielle optische Meßeinrichtungen entwickelt, die zwar eine genaue Spalteinstellung gewährleisten, jedoch sowohl vom Aufbau als auch von der Handhabung her recht kompliziert und aufwendig sind, was vor allem den Geräteservice erschwert.PENTAKTA K 100) developed special optical measuring devices that ensure an exact gap setting, but both in terms of structure and in terms of handling are quite complicated and time-consuming, which is particularly important for device service difficult.

Der Erfindung liegt nun die Aufgabe zugrunde, auf einfache Weise eine genaue Justierung des Walzenspaltes zu gewährleisten.The invention is based on the object in a simple manner to ensure precise adjustment of the roller gap.

Zur erfindungsgemäßen Lösung dieser Aufgabe ist vorgesehen, daß die Walzen so ausgebildet werden, daß in jedem Endbereich der Walzen Oberflächenbereiche vorzugsweise als Stirnplatten aus einem festen Werkstoff, insbesondere Metall, vorgesehen sind, die das gleiche Auß endurchmess ermaß aufweisen wie der elastische Belag, wobei an Walzen eines Walzenpaares diese festen Oberflächenbereiche jeweils gegenüber angeordnet sind.To solve this problem according to the invention it is provided that the Rolls are formed so that in each end region of the rollers surface areas preferably as end plates made of a solid material, in particular Metal, are provided, which have the same outer diameter as the end diameter elastic covering, with these solid surface areas on rollers of a roller pair are each arranged opposite.

In detaillierterer Ausbildung der Erfindung ist bei den Walzen auf einem dünnen festen Walzenkern der elastische Belag in einer dickeren Schicht aufgebracht, wobei die metallischen Stirnplatten als Ringe gleicher Breite, die je mit einem Absatz in eine Ausnehmung des elastischen Belages an jedem von dessen Enden ragen, auf dem Walzenkern befestigt sind.In a more detailed embodiment of the invention is on the rollers the elastic covering is applied in a thick layer to a thin solid roller core, the metallic face plates as rings of equal width, each with a Paragraph protrude into a recess of the elastic covering at each of its ends, are attached to the roller core.

Die Erfindung ist anhand eines Ausführungsbeispieles näher dargestellt und beschrieben. In der Zeichnung ist ein erfindungsgemäß ausgebildetes Walzenpaar gezeigt.The invention is illustrated in more detail using an exemplary embodiment and described. In the drawing is a roller pair designed according to the invention shown.

Wie nicht näher dabei dargestellt, sind die Walzen 1 und 2 in bekannter Weise so gelagert, daß die Walze 1 in ortsfesten Lagern drehbar ist, während die Walze 2 in ihrer Lagerung höhenverschiebbar ausgebildet ist, daß.der Spalt 6 zwischen den Walzen 1 und 2 in der jeweils erforderlichen Weite eingestellt werden kann.As not shown here, the rollers 1 and 2 are known Way mounted so that the roller 1 is rotatable in stationary bearings, while the Roller 2 is designed to be vertically displaceable in its storage, that the gap 6 between the rollers 1 and 2 can be adjusted to the required width.

Nach der Erfindung sind die Walzen 1 und 2 dabei so ausgebildet, daß auf je einem dünnen Walzenkern 5 ein dickerer Belag 4 aus Gummi aufgebracht ist. Dieser Belag 4 weist an den Enden Ausnehmungen auf, in die jeweils Absätze von ringförmigen Stirnplatten 3 greifen.According to the invention, the rollers 1 and 2 are designed so that a thicker covering 4 made of rubber is applied to each thin roller core 5. This covering 4 has recesses at the ends, in each of which shoulders of annular Grasp the front plates 3.

Die Stirnplatten 3 sind an diesen Enden befestigt. Sie weisen außer in den Bereichen des Absatzes das gleiche Außendurchmessermaß auf wie der Belag 4, was sich technologisch beispielsweise so realisieren läßt, indem jede Walze 1 oder 2 auf Belag 6 und Stirnplatten 3 durchgehend überschliffen wird. Die Walze 1 und 2 eines Walzenpaares sind dabei von gleicher Breite, so daß sich die Stirnplatten 3 jeweils genau gegenüber liegen.The face plates 3 are attached to these ends. They show except the same outside diameter as the covering in the areas of the shoulder 4, which can be achieved technologically, for example, by placing each roller 1 or 2 on deck 6 and face plates 3 continuously ground will. The roller 1 and 2 of a roller pair are of the same width, so that the end plates 3 are each exactly opposite.

Damit wird folgende erfindungsgemäße Funktion gewahrleistet: Zur genauen Einstellung des erforderlichen Spaltes 6 zwischen den Walzen 1 und 2 des Walzenpaares genügt es, eine Fühllehre an jedem Spaltende zwischen den Stirnplatten 3 einzulegen und die Walzen dann in ihrer Lagerung auf dieses Spaltmaß in bekannter Weise ( z. B. mittels Schrauben in Langlöchern ) fest einzustellen. Da die Fühllehren zwischen zwei festen Elemerten, den Stirnplatten 3, liegen, ist keine Deformation der Walzenoberfläche mehr möglich, die zu Ungenauigkeiten des Spaltmaßes führen könnte. Damit wird auf einfache Weise eine sichere Spalteinstellung von hoher Genauigkeit gewährleistet.This ensures the following function according to the invention: For precise Adjustment of the required gap 6 between rollers 1 and 2 of the roller pair it is sufficient to insert a feeler gauge between the end plates 3 at each end of the gap and then the rollers in their storage on this gap dimension in a known manner (z. B. by means of screws in elongated holes). Since the feeler gauges between two fixed elements, the face plates 3, are not deformation of the roll surface more possible, which could lead to inaccuracies in the gap. This is on simple way ensures a safe gap setting of high accuracy.
