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 Trennband 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 1044 043 ein Vervielfältigungsgerät beschrieben, bei dem Druckpapierblätter an einer umlaufenden Matrize vorbeigefühlt 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 1044 043 a duplicating machine is described in which sheets of printing paper 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 and tear 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 da- 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 separating tape are only minimal Are subject to wear and tear.
Diese Aufgabe wird erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Mitteingelöst.This object is achieved according to the invention with those specified in the characterizing part of claim 1 Middle redeemed.
Durch das erfindungspemäß 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.The lateral deflection of the separating tape 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 matter of the subclaims.
Die Erfindung wird nachstehend anhand der Beschreibung eines Ausführungsbeispiels unter Bezugnahme
auf die Zeichnung näher erläutert. Es zeigt
F i g. 1 einen Längsschnitt eines Kopiergeräts,The invention is explained in more detail below on the basis of the description of an exemplary embodiment with reference to the drawing. It shows
F i g. 1 shows a longitudinal section of a copier,
to Fig.2 eine perspektivische Ansicht der Trennvorrichtung undto Fig.2 a perspective view of the separating device and
F i g. 3 einen Querschnitt der in F i g. 3 dargestellten Vorrichtung.
Das in F i g. 1 gezeigte Kopiergerät besitzt eine elektrophotographische Trommel 7, die auf ihrem
Umfang ein Aufzeichnungsmaterial 8 als Bildträgermaterial aufweist. Um die sich in der angegebenen
Pfeilrichtung drehende Trommel 7 herum sind ein erster Lader 9, eine Einrichtung 10, mit deren Hilfe gleichzeitig
eine Bildprojektion und eine Entladung durchgeführt werden, eine Totalbelichtungseinrichtung 11, eine
Entwicklungseinrichtung 12, ein dritter Lader 13, eine Bildübertragungseinrichtung 14 und eine Reinigungseinrichtung
15 in der genannten Reihenfolge angeordnet. Mit Hilfe der Einrichtungen 9 bis 11 wird ein dem
Vorlagenbild entsprechendes elektrostatisches Ladungsbild erzeugt, das in der Entwicklungseinrichtung
12 entwickelt und in der Übertragungseinrichtung 14 auf Bildempfangsmaterial, d. h. auf Kopierpapier Pübertragen
wird. Das Kopierpapier P wird von einem Kopierpapierstapel mittels einer Zuführungseinrichtung
aus einer Vereinzelungsrolle 79 und Zuführungsrollenpaaren 81 und 82 zur Bildübertragungseinrichtung 14
gefördert. Nach der Bildübertragung wird das einzelne Kopierpapierblatt mittels einer Trennvorrichtung von
der elektrophotographischen Trommel 7 abgelöst und gelangt in eine Fixiereinrichtung, bevor es aus Hern
Kopiergerät ausgetragen wird.F i g. 3 shows a cross section of the FIG. 3 device shown.
The in Fig. 1 has an electrophotographic drum 7, which has a recording material 8 as an image carrier material on its periphery. Around the drum 7 rotating in the indicated arrow direction are a first charger 9, a device 10 with the aid of which image projection and discharge are carried out simultaneously, a total exposure device 11, a developing device 12, a third charger 13, an image transfer device 14 and a cleaning device 15 arranged in the order mentioned. 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. After the image transfer, the individual copy paper sheet is detached from the electrophotographic drum 7 by means of a separating device and reaches a fixing device before it is discharged from the copier.
Wie in Fig.3 dargestellt ist, ist die elektrophotographische Trommel 7 parallel zur Trommelachse an der Stelle 7| abgeflacht. Beide Enden des blattförmigen Aufzeichnungsmaterials 8 sind durch Halteplatten 8| und 82 festgehalten.As shown in Fig.3, the electrophotographic Drum 7 parallel to the drum axis at point 7 | flattened. Both ends of the leaf-shaped Recording material 8 are held by holding plates 8 | and 82 recorded.
An beiden Stirnseiten der Trommel befinden sich 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.On both front sides of the drum there are coaxially arranged disks 45 and 46, which are rotate independently of each other. Front parts of an image transfer roller 47 roll on the disks 45 and 46, which is slightly longer than the axial dimension of the drum 7. The diameter of the disks 45 and 46 is the same that of the drum 7 with the recorded recording material 8, so that the transfer roller 47 is fixed is pressed 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 separating tape 49 from the guide rollers 50 to 54 out of the path of movement of the copy paper is deflected.
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. Übertragungswalze 47 gelangt und dadurch über seine gesamte Breite vom Aufzeichnungsmaterial 8 abgelöst wird, nachdem das Tonerbild vom Aufzeichnungsmaterial 8 auf das Kopierpapier ρ übertragenThe F i g. 2 and 3 show that one side edge of the copy paper P entering the transfer device passes between the separating belt 49 and the separating or transfer roller 47 and is thereby detached from the recording material 8 over its entire width after the toner image from the recording material 8 onto the Copy paper ρ transferred
wurde. Danach wird das Kopierpapier mit Hilfe eines sich in leichtem Kontakt mit der Trenn- bzw. Übertragungswalze 47 befindenden Trennfingers 83 (Fig. 1) an die Fixiereinrichtung weiterbewegt.became. After that, the copy paper is made with the help of a separating fingers 83 which are in light contact with the separating or transfer roller 47 (Fig. 1) moved on to the fixing device.
Bewegt sich das Aufzeichnungsmaterial 8 auf der Trommel 7 von der Trenn- bzw. Übertragungswalze 47 fort, so bildet sich ein Zwischenraum t zwischen dieser, wie es in F i g. 3 gezeigt ist. Die Scheiben 45 und 46 bleiben jedoch mit der Trenn- bzw. Übertragungswalze 47 in Kontakt, wie dies zuvor beschrieben wurde, so daß die Walze 47 weitergedreht wird und das aufliegende Trennband 49 weilerbewegt wird. Selbst wenn also die Trommel 7 stillgesetzt wird, werden die Walze 47 und das Trennband 49 so weiterbewegt, daß das Kopierpapier P aktiv in die Fixiereinrichtung 55 gefördert und eine örtliche Erhitzung der Walze 47 und des Trennbands 49 durch die Fixiereinri^htung 55 verhindert wird.If the recording material 8 moves on the drum 7 away from the separating or transfer roller 47, a gap t is formed between the latter, as shown in FIG. 3 is shown. The disks 45 and 46, however, remain in contact with the separating or transfer roller 47, as previously described, so that the roller 47 is rotated further and the separating belt 49 lying thereon is moved while. Even if the drum 7 is stopped, the roller 47 and the separating belt 49 are moved further in such a way that the copy paper P is actively conveyed into the fixing device 55 and local heating of the roller 47 and the separating belt 49 by the fixing device 55 is prevented.
