Description

Die Erfindung betrifft eine Abdeckklappe für den Papiereinlauf einer Büromaschine, insbesondere eines Aktenvernichters.The invention relates to a cover flap for the paper inlet an office machine, especially a document shredder.

Es ist bereits bekannt, an Büromaschinen Abdeckklappen vorzuse­ hen, um eine Geräuschminderung zu erreichen. Derartige Abdeck­ klappen sind beispielsweise auch bereits bekannt bei Druckern für Endlospapiere. Diese Abdeckungen weisen für den Einlauf des Endlospapiers einen Spalt auf. Dieser Spalt ist erforderlich, da der Einzug des Endlospapiers aufgrund der in diesen Geräten zur Verfügung stehenden geringen Antriebskräfte für den Papier­ vorschub in keiner Weise abgebremst werden darf. Aus dem Spalt ergibt sich jedoch der Nachteil, daß eine optimale Geräuschmin­ derung nicht zu erzielen ist.It is already known to cover flaps on office machines hen to achieve noise reduction. Such cover flaps are also known, for example, from printers for continuous forms. These covers point for the inlet of the A gap. This gap is required because the feeding of the continuous forms due to the in these devices available low driving forces for the paper feed must not be slowed down in any way. From the gap However, there is the disadvantage that an optimal noise level cannot be achieved.

Der Erfindung liegt die Aufgabe zugrunde, eine Abdeckklappe zu schaffen, die eine optimale Geräuschminderung sicherstellt und außerdem den Einlauf von Endlospapier, insbesondere in Aktenver­ nichtern verbessert.The invention has for its object to a cover flap create that ensures optimal noise reduction and also the infeed of continuous paper, especially in file ver not improved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Bereich der Unterseite der Abdeckklappe auf dem in die Büromaschine ein­ laufenden Papier aufliegt. Zweckmäßigerweise ist das Papier zwi­ schen dem Bereich an der Unterseite der Abdeckklappe und dem Ge­ häuseoberteil der Büromaschine hindurchgeführt. Vorteilhaft ist es, wenn die Abdeckklappe an ihrer der Papierlaufrichtung ent­ gegengesetzten Kante an der Unterseite eine Abschrägung aufweist. This object is achieved in that an area the bottom of the cover flap on the in the office machine running paper. The paper is expediently between the area on the underside of the cover flap and the Ge passed through the upper part of the office machine. It is advantageous it when the cover flap is in the direction of paper travel opposite edge has a bevel on the underside.  

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß beispielsweise bei Aktenvernichtern die Abdeckklappe den Raum oberhalb des Schneidwerkes völlig abschließt und daß somit eine optimale Geräuschminderung erzielt werden kann. Über­ raschenderweise hat es sich gezeigt, daß die Papiereinzugskräfte bei Aktenvernichtern groß genug sind, um das Endlospapier unter der Abdeckklappe hindurch einzuziehen und daß die Abdeckklappe aufgrund ihres Eigengewichts das Papier glättet und ein Schief­ laufen verhindert. Aufgrund der erfindungsgemäßen Anordnung ei­ ner Abdeckklappe ist es gelungen, auch unter ungünstigen Bedin­ gungen den Einlauf von Endlospapier absolut störungsfrei zu ge­ stalten.The advantages that can be achieved with the invention are in particular in the fact that the cover flap, for example, for document shredders completely closes the space above the cutting unit and that thus an optimal noise reduction can be achieved. About Surprisingly, it has been shown that the paper feed forces for shredders are large enough to hold the continuous paper underneath the cover flap to pull in and that the cover flap due to its own weight the paper smoothes and a skew prevents running. Due to the arrangement according to the invention A cover flap has succeeded, even under unfavorable conditions the entry of continuous paper was absolutely trouble-free design.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dar­ gestellt und wird im folgenden näher beschrieben. Es zeigenAn embodiment of the invention is shown in the drawing and is described in more detail below. Show it

Fig. 1 einen Querschnitt durch einen Aktenvernichter für Endlosformulare, Fig. 1 shows a cross section through a shredder for continuous forms,

Fig. 2 eine vergrößerte Darstellung der auf dem Endlospapier aufliegenden Abdeckklappe. Fig. 2 is an enlarged view of the cover flap resting on the continuous paper.

In der Zeichnung ist mit 1 ein Aktenvernichter bezeichnet. Der Aktenvernichter 1 weist ein aus zwei Schneidwalzen 2 und 3 be­ stehendes Schneidwerk auf, das unterhalb eines Zuführschachtes 4 angeordnet ist. Beidseitig des Aktenvernichters 1 sind Anlage­ tische 5 und 6 für Endlospapierstapel 7 und 8 angeordnet. Von den Endlospapierstapeln 7 und 8 sind Papierbahnen 7 a und 8 a über das Gehäuseoberteil 9 des Aktenvernichters 1 in den Zuführ­ schacht 4 und weiter an das Schneidwerk mit den Schneidwalzen 2 und 3 geführt. Im Schneidwerk wird das Papier zerkleinert.In the drawing, 1 denotes a document shredder. The document shredder 1 has a cutting mechanism consisting of two cutting rollers 2 and 3 , which is arranged below a feed shaft 4 . On both sides of the shredder 1 , system tables 5 and 6 for continuous paper stack 7 and 8 are arranged. Of the continuous paper stacks 7 and 8 paper webs 7 a and 8 a via the upper housing part 9 of the document shredder 1 in the feed shaft 4 and further to the cutting unit with the cutting rollers 2 and 3 . The paper is shredded in the cutter.

Oberhalb des Zuführschachtes 4 sind zwei Abdeckklappen 10 und 11 angeordnet. Ein am Gehäuse befestigtes Scharnier ermöglicht ein Verschwenken der Abdeckklappen 10 und 11 in die in der Fig. 1 der Zeichnung gestrichelt dargestellte Position. Hierdurch wird es ermöglicht, in den Zuführschacht, d. h. in das Schneidwerk das Papier einzuführen. Die Abdeckklappen 10 und 11 liegen in der in Fig. 1 der Zeichnung dargestellten Position auf dem Ge­ häuseoberteil 9 bzw. auf den Papierbahnen 7 a und 8 a auf. Die vergrößerte Darstellung in Fig. 2 der Zeichnung zeigt die auf der Endlospapierbahn 8 aufliegende Abdeckklappe 11. Außerdem ist hier die an den Abdeckklappen 10 und 11 vorgesehene Abschrä­ gung 13 an den der Papierlaufrichtung entgegengerichteten Kan­ ten 14 dargestellt. Die Abschrägung 13 unterstützt die vorteil­ hafte Wirkung der auf dem Papier aufliegenden Abdeckklappen 10 und 11 für den Papierlauf.Two cover flaps 10 and 11 are arranged above the feed shaft 4 . A hinge attached to the housing enables the cover flaps 10 and 11 to be pivoted into the position shown in dashed lines in FIG. 1 of the drawing. This makes it possible to insert the paper into the feed chute, ie into the cutting unit. The cover flaps 10 and 11 are in the position shown in Fig. 1 of the drawing on the Ge housing upper part 9 and on the paper webs 7 a and 8 a . The enlarged illustration in FIG. 2 of the drawing shows the cover flap 11 resting on the continuous paper web 8 . In addition, here the provided on the flaps 10 and 11 bevel 13 on the opposite direction of the paper th 14 shown. The bevel 13 supports the advantageous effect of the cover flaps 10 and 11 resting on the paper for the paper run.

Wie aus der Zeichnung ersichtlich ist, verschließen die Abdeck­ klappen 10 und 11 den Zuführschacht 4 und damit das Schneidwerk völlig, so daß eine optimale Geräuschminderung erreicht wird. Selbstverständlich ist es möglich, anstelle der in dem Ausfüh­ rungsbeispiel dargestellten zwei Abeckklappen 10 und 11 bei an­ deren Gerätetypen gegebenenfalls auch nur eine einzige Abdeck­ klappe anzuordnen. Wesentlich ist, daß die Abdeckklappe während des Papiereinzuges auf dem Papier aufliegt und den Zuführschacht, d.h. den Raum oberhalb des Schneidwerkes völlig abschließt. Die Abdeckklappe ist vorteilhafterweise transparent ausgebildet und liegt mit ihrem Eigengewicht auf dem Papier auf. Die Auflage­ kraft auf dem Papier kann mittels des Eigengewichts der Abdeck­ klappe an die Erfordernisse angepaßt werden. Gegebenenfalls ist eine Beaufschlagung mit einer Federkraft denkbar.As can be seen from the drawing, the cover flaps 10 and 11 close the feed chute 4 and thus the cutting mechanism completely, so that optimum noise reduction is achieved. Of course, it is possible, instead of the two flaps 10 and 11 shown in the embodiment, to arrange, if necessary, only a single flap on their device types. It is essential that the cover flap rests on the paper during the paper feed and completely closes off the feed shaft, ie the space above the cutting unit. The cover flap is advantageously transparent and lies on the paper with its own weight. The force on the paper can be adapted to the requirements by means of the dead weight of the cover flap. If necessary, a spring force can be applied.
