Description

Die Erfindung bezieht sich auf eine Trennvorrichtung zum Ablösen eines Bildempfangsmaterials von einem Bildträgermaterial nach der Bildübertragung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a separating device for separating an image receiving material from a Image carrier material after image transfer according to the preamble of claim 1.

Bei einer Trennvorrichtung gemäß einem älteren Vorschlag ist das Trennbänd so über Rollen geführt, daß es sowohl bei seiner Hinbewegung als auch bei seiner Rückbewegung zwischen dem Bildempfangsmaterial und dem Bildträgermaterial verläuft. Dies hat den Nachteil, daß die Innenflächen des Trennbands im Ablösebereich einander berühren und verschleißen. Ebenso ist das Bildträgermaterial dort, wo es von dem Trennband berührt wird, einem Verschleiß unterworfen.In a separating device according to an older proposal, the separating tape is guided over rollers that it both in its forward motion and in its return motion between the image receiving material and the image carrier material. This has the disadvantage that the inner surfaces of the separating tape in the Separation areas touch each other and wear out. Likewise, the image carrier material is where it is from the Separating tape is touched, subject to wear.

Ferner ist in der FR-PS 10 44 043 ein Vervielfältigungsgerät beschrieben, bei dem Druckpapierblätter an einer umlaufenden Matrize vorbeigeführt und mittels einer Walzenanordnung für den Druckvorgang gegen die Matrize gepreßt werden. Das Ablösen der Druckpapierblätter von der Matrize besorgt ein Endlosband, das an einem Rand der umlaufenden endlosen Matrize auf derselben mitumläuft und mittels einer Hebel-Rollenanordnung aus der Matrizenumlaufbahn derart abgehoben ist, daß sich der Seitenrand des Druckpapierblatts nach Durchlaufen der Walzenanordnung von der Matrize löst. Unter dem Einfluß des Eigengewichts löst sich dann das Druckpapier vollständig von der Matrize. Dieses direkte Umlaufen des Endlosbands auf der Matrize begründet einen erheblichen Verschleiß von Endlosband und Matrize.Furthermore, in FR-PS 10 44 043 a duplicating machine is described in which sheets of printing paper passed a rotating die and counteracted by means of a roller arrangement for the printing process the die can be pressed. The peeling of the printing paper sheets from the stencil is a concern Endless belt that rotates along one edge of the circulating endless die on the same and by means of a lever-roller arrangement is lifted from the die orbit in such a way that the side edge of the Separates the printing paper sheet from the die after passing through the roller arrangement. Under the influence of the The printing paper then detaches itself completely from the die under its own weight. This direct circumnavigation of the Endless belts on the die cause considerable wear on the endless belt and die.

Der Erfindung liegt die Aufgabe zugrunde, eine Trennvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 zu schaffen, bei der sowohl das Bildträgermaterial als auch das Trennband nur geringem Verschleiß unterworfen sind.The invention is based on the object of a separating device according to the preamble of the patent claim 1, in which both the image carrier material and the release tape are only slightly Are subject to wear and tear.

Diese Aufgabe wird erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Mitteln gelöst.This object is achieved according to the invention with those specified in the characterizing part of claim 1 Funds resolved.

Durch das erfindungsgemäß vorgesehene seitliche Auslenken des Trennbands aus der Bewegungsbahn des Bildempfangsmaterials gibt es keine Trennbandbereiche, die in gegenseitiger Berührung stehen bzw. auf dem Bildträgermaterial reiben, so daß ein minimaler Bandverschleiß und damit eine hohe Lebensdauer des Trennbands garantiert sind und auch das Bildträgermaterial so wenig wie möglich beansprucht wird.As a result of the lateral deflection of the separating strip from the movement path of the provided according to the invention There are no separating tape areas that are in mutual contact or on the image receiving material Image carrier material rub, so that minimal wear and tear of the tape and thus a long service life of the Partition tape are guaranteed and the image carrier material is stressed as little as possible.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous further developments of the invention are the subject of the subclaims.

With the aid of the devices 9 to 11, an electrostatic charge image corresponding to the original image is generated, which is developed in the developing device 12 and transferred in the transfer device 14 to image receiving material, ie to copy paper P. The copy paper P is conveyed from a copy paper stack by means of a feed device comprising a separating roller 79 and feed roller pairs 81 and 82 to the image transfer device 14.

koaxial angeordnete Scheiben 45 und 46, die sich unabhängig voneinander drehen. Auf den Scheiben 45 und 46 rollen Stirnteile einer Bildübertragungswalze 47, die etwas länger als die axiale Abmessung der Trommel 7 ist. Der Durchmesser der Scheiben 45 und 46 ist gleich dem der Trommel 7 mit dem aufgespannten Aufzeichnungsmaterial 8, so daß die Übertragungswalze 47 fest gegen das Aufzeichnungsmaterial 8 gedrückt wird.coaxially arranged disks 45 and 46 which rotate independently of each other. On the discs 45 and 46 roll end portions of an image transfer roller 47 which are slightly longer than the axial dimension of the drum 7 is. The diameter of the disks 45 and 46 is the same as that of the drum 7 with the recorded recording material 8 so that the transfer roller 47 is pressed firmly against the recording material 8.

Ein das Kopierpapier vom Aufzeichnungsmaterial ablösendes Trennband 49 ist über 180° um die zugleich als Trennwalze dienende Übertragungswalze 47 herumgeschlungen und durch Führungsrollen 50 bis 54 so geführt, daß es zusammen mit der Trenn- bzw. Übertragungswalze 47 bewegt wird. Fig.2 läßt klar erkennen, daß das Trennband 49 von den Führungsrollen 50 bis 54 aus der Bewegungsbahn des Kopierpapiers ausgelenkt wird.A separating tape 49 detaching the copy paper from the recording material is 180 ° around the same Serving as a separating roller transfer roller 47 wrapped around and by guide rollers 50 to 54 so out that it is moved together with the separation or transfer roller 47. Fig.2 makes it clear recognize that the release tape 49 from the guide rollers 50 to 54 is deflected from the path of movement of the copy paper.

Die F i g. 2 und 3 zeigen, daß das in die Übertragungseinrichtung eintretende Kopierpapier P mit seinem einen Seitenrand zwischen das Trennband 49 und die Trenn- bzw.

Then the copy paper is in slight contact with the separator or separator with the help of a sjch. Transfer roller 47 located separating finger 83 (Fig. 1) moved on to the fixing device.

Bewegt sich das Aufzeichnungsmaterial 8 auf der Trommel 7 von der Trenn- bzw.
