Abstract

The material (B) which is moved to a vertical position is fixed by clamping between two conveying means, at least one of which is constructed as a continuously circulating flat belt (F). The second conveying means is formed by a smooth-faced, curved guide fence (LZ), along whose outwardly arched face the flat belt runs. The coefficient of friction between the flat belt (F) and material (B) in comparison with the coefficient of friction between the material and the guide fence (LZ) and also the contact pressure of the flat belt (F) against the material (B) or the guide fence (LZ) are selected to be of such a magnitude that the material follows the conveying movement of the flat belt. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Transportvorrichtung für blatt- oder folienförmiges Transportgut nach dem Oberbegriff des Anspruchs 1.The invention relates to a transport device for sheet or film-shaped transport goods according to the preamble of claim 1.

Bei Belegverarbeitungseinrichtungen durchlaufen die einzelnen Belege zwischen Eingabefach und den meist mehrfach vorhandenen Ablagefächern je nach Größe der Einrichtung eine mehr oder weniger lange Wegstrecke. Die dafür notwendigen Transportmittel sind längs der gesamten Strecke. meist nicht gleichartig, sondern in Anpassung an die verschiedenen Funktionsbausteine längs der Wegstrecke - z.B. Lesestation,Stempelstation, Mikrofilmeinrichtung, Ablagefachbereich - unter Berücksichtigung bestimmter Forderungen entsprechend verschiedenartig ausgebildet. Die Belege können beispielsweise zwischen paarweise aneinanderlaufenden Rollen, zwischen zwei aneinanderlaufenden Flachriemen mit zugehörigen Spann- und Umlenkrollen oder zwischen Rollen und Flachriemen transportiert und geführt werden. Für jedes dieser Transportmittel gilt die Bedingung, daß der Abstand zwischen zwei längs der Strecke aufeinanderfolgenden Rollen kürzer als die minimale Beleglänge ist, damit der Beleg stets von wenigstens einer Rolle bzw. einem Rollenpaar erfaßt wird. Derartige Transportmittel sind deshalb wegen der Vielzahl der Rollen konstruktiv aufwendig und dementsprechend teuer.In the case of document processing devices, the individual documents between the input compartment and the storage compartments, which are usually present multiple times, travel a more or less long distance depending on the size of the device. The means of transport required for this are along the entire route. mostly not of the same type, but in adaptation to the various function blocks along the route - e.g. Reading station, stamping station, microfilm device, storage compartment area - designed in different ways, taking certain requirements into account. The documents can be transported and guided, for example, between rollers running in pairs, between two flat belts running together with associated tensioning and deflecting rollers, or between rollers and flat belts. The condition for each of these means of transport is that the distance between two rolls in succession along the route is shorter than the minimum document length, so that the document is always recorded by at least one roll or a pair of rolls. Such means of transport are therefore structurally complex due to the large number of roles and accordingly expensive.

Der vorliegenden Erfindung lag deshalb die Aufgabe zugrunde, für eine Transporteinrichtung für blatt- oder folienförmiges Transportgut einen konstruktiv einfachen und damit kostengünstigen Weg aufzuzeigen.The present invention was therefore the object reasons, for a transport device for sheet or film-shaped transport goods to show a structurally simple and therefore inexpensive way.

Die Lösung dieser Aufgabe ergibt sich erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben. Der Vorteil einer derart ausgebildeten Transportvorrichtung ergibt sich vor allem durch den aus konstruktiver Sicht sehr einfachen mechanischen Aufbau, der sich insbesondere bei größeren Wegstrecken äußerst kostengünstig auswirkt.This object is achieved according to the invention by the characterizing features of patent claim 1. Advantageous further developments are specified in the subclaims. The advantage of a transport device designed in this way results above all from the very simple mechanical construction from a structural point of view, which has an extremely cost-effective effect, particularly over long distances.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Dabei zeigen

  • FIG 1 einen Ausschnitt aus einer Beleglaufstrecke unter Verwendung erfindungsgemäß ausgebildeter Transportvorrichtungen,
  • FIG 2,3 das Prinzip einer-Transportvorrichtung in einer Beleglaufstrecke gemäß FIG 1 in Vorder-und Draufsicht.
An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. Show
  • 1 shows a section of a document path using transport devices designed according to the invention,
  • 2, 3 the principle of a transport device in a document path according to FIG. 1 in front and top view.

Die FIG 1 zeigt einen Ausschnitt aus einer Beleglaufstrecke mit einem über mehrere Umlenk- und Spannrollen R geführten endlosen Flachriemen F, bei der in zwei längeren Wegstrecken jeweils ein sogenannter Leitzaun LZ1, 2 vorgesehen ist. Dieser Leitzaun LZ1, 2 besteht aus einem gekrümmten Streifen aus Blech oder einem ähnlich geeignetem Material, dessen nach außen gewölbte Fläche vom Flachriemen F umspannt ist, wobei ein dazwischen transportierter Beleg relativ gleichmäßig gegen den Blechstreifen gedrückt wird. Aufgrund des höheren Reibungskoeffizienten zwischen Flachriemen F und dem vorzugsweise aus Papier bestehenden Beleg im Vergleich zum Reibungskoeffizienten zwischen Beleg und Leitzaun haftet der Beleg am Flachriemen und wird von diesem in Transportrichtung mitgezogen. Die Lage des Beleges während des Transports ist weitgehend nur vom Flachriemen F bestimmt und durch die große Flächenberührung dementsprechend gut fixiert.1 shows a section of a document path with an endless flat belt F guided over several deflection and tensioning rollers R, in which a so-called guide fence LZ1, 2 is provided in each of two longer distances. This guide fence LZ1, 2 consists of a curved strip of sheet metal or a similarly suitable material, the outwardly curved surface of which is encompassed by the flat belt F, a document transported between them being pressed relatively evenly against the sheet metal strip. Due to the higher coefficient of friction between flat belt F and the preferably paper document in the In comparison to the coefficient of friction between the slip and guide fence, the slip adheres to the flat belt and is pulled along by it in the transport direction. The position of the document during transport is largely determined only by the flat belt F and accordingly well fixed due to the large surface contact.

Das Prinzip dieser Transportvorrichtung wird im folgenden anhand der Figuren 2 und 3 näher erläutert. Diese Figuren 2, 3 zeigen in Vorder- und Draufsicht einen Leitzaun LZ und einen endlosen, zwischen zwei Umlenkrollen R geführten Flachriemen F, der sich längs des Leitzauns LZ an dessen nach außen gekrümmter Fläche anschmiegt. Zwischen Leitzaun LZ und Flachriemen F befinden sich zwei Belege B, die durch den Flachriemen F gegen den Leitzaun LZ gedrückt werden. Anpreßdruck und der aufgrund unterschiedlicher Materialien für Leitzaun LZ und Flachriemen F größere Reibungskoeffizient zwischen Flachriemen und Beleg im Vergleich zum Reibungskoeffizienten zwischen Beleg und Leitzaun sorgen dafür, daß der Beleg am Flachriemen haftet und von diesem mitgezogen wird. Je nach Papiersorte ergeben sich für die Reibung zwischen Flachriemen und Papier durchschnittliche Reibwerte zwischen 0,6 und 0,8, während die entsprechenden Reibwerte für die Reibung zwischen Papier und Leitzaun zwischen 0,2 und 0,25 schwanken. Die Krümmung des Leitzauns LZ ist zweckmäßig so gewählt, daß sich längs des Leitzauns ein gleichmäßiger Anpreßdruck durch den Flachriemen F ergibt. Der ideale Krümmungsverlauf - unter Vernachlässigung des Umschlingungseinflusses seitens des Flachriemens - würde durch die Nachbildung der sogenannten Seilkurve oder der sogenannten elastischen Linie er-' reicht. Im dynamischen Betrieb muß deshalb der Einfluß der Umschlingung entsprechend berücksichtigt werden. Der Krümmungsradius muß jedenfalls einen genügend großen Sicherheitsabstand gegenüber einem Krümmungsradius gegen unendlich haben, damit das Verhältnis von Riemenspannkraft zu resultierender Andruckkraft nicht zu groß wird.The principle of this transport device is explained in more detail below with reference to FIGS. 2 and 3. These FIGS. 2, 3 show a front and top view of a guide fence LZ and an endless flat belt F, which is guided between two deflecting rollers R and which nestles along the guide fence LZ on its outwardly curved surface. There are two documents B between the guide fence LZ and the flat belt F, which are pressed against the guide fence LZ by the flat belt F. Contact pressure and the greater coefficient of friction between the flat belt and the slip due to different materials for the guide fence LZ and flat belt F compared to the coefficient of friction between the slip and guide fence ensure that the slip adheres to the flat belt and is pulled by it. Depending on the type of paper, average friction values for the friction between flat belt and paper are between 0.6 and 0.8, while the corresponding friction values for the friction between paper and guide fence fluctuate between 0.2 and 0.25. The curvature of the guide fence LZ is expediently chosen so that there is a uniform contact pressure through the flat belt F along the guide fence. The ideal curvature - neglecting the Umschlingungseinflusses part of the flat belt - would replaced by a replica of the so-called catenary curve, or the so-called elastic line ranges'. In dynamic operation, the influence of the belt must therefore be taken into account accordingly the. In any case, the radius of curvature must have a sufficiently large safety margin with respect to a radius of curvature that is infinite so that the ratio of belt tensioning force to resulting pressure force does not become too great.
