Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device according to the preamble of patent claim 1.

Eine Reinigungseinrichtung für einen Zwischenbildträger bei einem nach dem elektrofotografischen Prinzip arbeitenden Druck- oder Kopiergerät ist z.B. aus der DE-PS 27 06 599 bekannt. Die Reinigungseinrichtung besteht dabei aus einer Bürste, einer Abzughaube und einer Abstreifkammer und in einem in der Abstreifkammer laufenden Schieber. Der Schieber ist dabei an einem Seil befestigt. Dieses Seil läuft mit einem Abschnitt in der Abstreifkammer und tritt jeweils an den Breitseiten der Abstreifkammer abgedichtet durch Dichtungen, aus dieser aus. Außerhalb der Abstreifkammer sind zwei Rollen angeordnet, über die das Seil läuft. Der andere Aschnitt des Seiles verläuft außerhalb der Abstreifkammer. Eine das Seil aufnehmende Seilscheibe wird von einem Motor angetrieben.A cleaning device for an intermediate image carrier in a printing or copying device working according to the electrophotographic principle is e.g. known from DE-PS 27 06 599. The cleaning device consists of a brush, an extractor hood and a stripping chamber and in a slide running in the stripping chamber. The slider is attached to a rope. This rope runs with a section in the stripping chamber and exits from the broad sides of the stripping chamber, sealed by seals. Outside the stripping chamber there are two rollers over which the rope runs. The other cut of the rope runs outside the stripping chamber. A rope sheave that receives the rope is driven by a motor.

Ähnliche Reinigungseinrichtungen zum Reinigen eines Koronadrahtes in einem Koronagenerator sind z.B. auch in der DE-OS 24 24 835 beschrieben.Similar cleaning devices for cleaning a corona wire in a corona generator are e.g. also described in DE-OS 24 24 835.

Ein wesentliches Problem bei derartigen Reinigungsvorrichtungen besteht in der Abdichtung des Toner enthaltenden Bereiches, wobei die Gefahr besteht, das Toner an dem Zugseil des Betätigungselementes haften bleibt und somit nach außen dringt. Um diese Gefahr zu verringern werden bei derartigen Einrichtungen im allgemeinen glatte und runde Zugseile verwendet, die ein leichteres Abdichten der Toner enthaltenden Bereiche ermöglichen. Derartige runde und glatte Seile rutschen nun auf Seilrollen leicht durch, was widerum die Positioniergenauigkeit des durch das Seil bewegten Betätigungselementes in dem abgedichteten Bereichen negativ beeinflußt.A major problem with such cleaning devices is the sealing of the area containing the toner, with the risk that the toner will stick to the pulling cable of the actuating element and thus penetrate to the outside. In order to reduce this danger, smooth and round traction cables are generally used in such devices, which enable the areas containing toner to be sealed more easily. Such round and smooth ropes now slip easily on rope pulleys, which in turn negatively affects the positioning accuracy of the actuating element moved by the rope in the sealed areas.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so auszugestalten, daß einerseits das Betätigungselement sicher positioniert werden kann, andererseits das Zugseil lecksicher durch die abgedichteten Bereiche führbar ist.The object of the invention is to design a device of the type mentioned in such a way that, on the one hand, the actuating element can be positioned securely, and on the other hand, the traction rope can be guided leak-proof through the sealed areas.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art gemäß dem kennziechnenden Teil des ersten Patentanspruches gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.This object is achieved in a device of the type mentioned at the outset in accordance with the characterizing part of the first claim. Advantageous embodiments of the invention are characterized in the dependent claims.

Erfindungsgemäß weist die Seilrolle auf ihrer Mantelfläche Führungsrillen für das Zugseil auf, die in mehreren Gängen links- oder rechtsgängig verlaufen. Die Seilrolle ist über ein Gewinde auf einer ortsfesten Drehachse angeordnet, wobei das Gewinde auf der Drehachse die gleiche Charakteristik nach Richtung Steigung hat, wie die Führungsrollen. Dadurch wird während der Bewegung der Seilrolle das Zugseil durch die Dichtungen des abgedichteten Bereiches in einem konstanten Winkel geradlinig geführt. Während des Auf- und Abroll-Vorganges des Zugseiles auf der Seilrolle kann es zu keinem Versatz des Seiles an den Verdichtungen kommen, wodurch das Seil lecksicher durch die Dichtungen geführt werden kann. Das mehrfache Umschlingen der Mantelfläche verhindert ein Durchrutschen des Seiles auf der Mantelfläche. Es ist außerdem auch möglich, das Seil auf der Mantelfläche der Seilrolle mit Hilfe einer Klemmeinrichtung zu fixieren.According to the invention, the rope pulley has guide grooves for the traction rope on its outer surface, which run left or right in several gears. The rope pulley is arranged on a thread on a fixed axis of rotation, the thread on the axis of rotation having the same characteristic in the direction of slope as the guide rollers. As a result, the traction cable is guided in a straight line through the seals of the sealed area at a constant angle during the movement of the pulley. During the winding and unwinding process of the traction rope on the rope pulley, there can be no displacement of the rope at the compressions, which means that the rope can be safely guided through the seals. The multiple looping of the outer surface prevents the rope from slipping on the outer surface. It is also possible to fix the rope on the outer surface of the pulley with the aid of a clamping device.

Die Führungsrollen auf der Mantelfläche der Seilrolle führen das Zugseil derart, daß beim Auf und Abwickeln des Seiles auf der Seilrolle, das Zugseil in den Führungsrillen verbleibt und sich nicht in Windungen übereinander legt. Damit wird das mit dem Zugseil verbundene Betätigungselement sicher und wiederholbar positioniert.The guide rollers on the outer surface of the rope pulley guide the pull rope in such a way that when the rope is wound up and unwound on the rope pulley, the pull rope remains in the guide grooves and does not overlap in turns. The actuating element connected to the pull rope is thus positioned safely and repeatably.

Die Verwendung von einem Kunststoff unmantelten Stahlseil ermöglicht eine besonders lecksichere Durchführung des Seiles durch die Dichtungen. Die Seilrolle selbst läßt sich aus thermoplastischen Kunststoff herstellen.The use of a steel cable with a plastic coating enables the rope to be run through the seals in a particularly leak-proof manner. The pulley itself can be made from thermoplastic.

Zur Erhöhung der Aufnahmekapazität der Seilrolle kann die Seilrolle im Winkel schräg zur Bewegungsrichtung des Zugseiles angeordnet sein.To increase the capacity of the rope pulley, the rope pulley can be arranged at an angle to the direction of movement of the pull rope.

Wird die Vorrichtung in einer Reinigungsstation in Druck- oder Kopiergeräten verwendet, bei dem sich in den abgedichteten Bereichen Tonerstaub befindet, so können zur Selbstreinigung der Seilrolle in die Führungsrillen der Seilrolle eingreifende Schaberelemente vorgesehen sein. Die Schaberelemente halten die Führungsrillen der Seilrolle frei von eventuell an dem Seil haftenden Tonerstaub. Damit wird eine Veränderung des Durchmessers der Mantelfläche infolge des Tonerstaubes verhindert.If the device is used in a cleaning station in printing or copying devices in which there is toner dust in the sealed areas, scraper elements engaging in the guide grooves of the rope pulley can be provided for self-cleaning of the rope pulley. The scraper elements keep the guide grooves of the rope pulley free of any toner dust adhering to the rope. This prevents a change in the diameter of the lateral surface due to the toner dust.

Eine Ausführungsform der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden beispielsweise näher beschrieben. Es zeigt

  • Fig. 1 eine schematische Darstellung einer Reinigungseinrichtung für einen Zwischenbildträger bei einem nichtmechanischen Druckgerät mit entsprechender Antriebsvorrichtung und
  • Fig. 2 eine schematische Darstellung der Seilrolle teilweise in Schnittdarstellung.
An embodiment of the invention is shown in the drawings and is described in more detail below, for example. It shows
  • Fig. 1 is a schematic representation of a cleaning device for an intermediate image carrier in a non-mechanical printing device with a corresponding drive device and
  • Fig. 2 is a schematic representation of the pulley partially in section.

Eine Reinigungseinrichtung für einen Zwischenbildträger bei einem nach dem elektrostatischen Prinzip arbeitenden Druck- oder Kopiergerät wie es z.B. im Prinzip nach der DE-PS 27 06 599 beschrieben ist, enthält eine einseitig offene Abstreifkammer AK in deren offene Seite eine hier nicht dargestellte Reinigungsbürste für eine Fotoleitertrommel des Druckgerätes ragt. Die Reinigungsbürste dient dazu, von der Fotoleitertrommel des Druckers den Toner zu entfernen und in der Abstreifkammer AK abzulagern. Zu diesem Zwecke befindet sich in der Abstreifkammer AK ein Schieber SH der über ein Seil S hin- und herbewegt werden kann und der die in der Abstreifkammer AK abgelagerten Tonerreste Absaugöffnungen OF zuführt. Die Abstreifkammer AK muß dabei absolut tonerdicht abgeschlossen sein, so daß in den umgebenden Antriebsbereich kein Tonerstaub dringen kann. Zu diesem Zwecke sind die Durchgangsöffnungen Do des Seiles S im Bereich der Abstreifkammer AK mit doppelten Dichtungen D versehen, die das kunststoffummantelte Stahlseil S nahezu staubdicht umschließen. Das Seil S ist dabei auf die Mantelfläche einer motorisch angetriebenen Seilrolle SR aufgewickelt. Als Gegenhalterung dient eine Umlenkrolle U, die das aus der Abstreifkammer AK austretende Seil umlenkt und hinter der Abstreifkammer wieder der Mantelfläche der Seilrolle SR zuführt. An diesem außerhalb der Abstreifkammer AK verlaufenden Teil des Seiles S befindet sich ein Fühlelement F, das z.B. aus einem Magneten besteht und das hier nicht dargestellte Schalter für einen Antriebsmotor M steuert. Die Funktion derartiger Schalter in Verbindung mit dem Antriebsmotor wird in der DE-PS 27 06 599 im Detail beschrieben. Der Antriebsmotor M greift über ein Getriebe G über einen Stift ST in die Seilrolle SR ein. Die Seilrolle ist drehbar auf einem Gewindebolzen B angeordnet, wobei der Gewindebolzen B fest auf einer Lasche des Druckergestelles befestigt ist.A cleaning device for an intermediate image carrier in a printing or copying machine working according to the electrostatic principle, as described, for example, in principle according to DE-PS 27 06 599, contains a stripping chamber AK which is open on one side and a cleaning brush (not shown here) for a photoconductor drum in the open side thereof of the pressure device protrudes. The cleaning brush is used to remove the toner from the photoconductor drum of the printer and to deposit it in the stripping chamber AK. For this purpose there is a slide SH in the stripping chamber AK which can be moved back and forth over a rope S and which feeds the toner residues OF which are deposited in the stripping chamber AK. The wiping chamber AK must be sealed absolutely toner-tight, so that no toner dust can penetrate into the surrounding drive area. For this purpose, the through openings Do of the rope S in the area of the stripping chamber AK are provided with double seals D, which enclose the plastic-coated steel rope S almost dust-tight. The rope S is wound on the outer surface of a motor-driven pulley SR. A deflection roller U serves as a counter-holder, which is the Scraper chamber AK deflects emerging rope and feeds back to the outer surface of the rope pulley SR behind the stripping chamber. On this part of the rope S which extends outside the stripping chamber AK there is a sensing element F which, for example, consists of a magnet and controls the switch (not shown here) for a drive motor M. The function of such switches in connection with the drive motor is described in DE-PS 27 06 599 in detail. The drive motor M engages the pulley SR via a gear G via a pin ST. The rope pulley is rotatably arranged on a threaded bolt B, the threaded bolt B being fixedly attached to a tab of the printer frame.

Die Seilrolle weist zur Aufnahme des Seiles S Führungsrillen FR auf, die in dem dargestellten Beispiel linksgängig verlaufen. Die gleiche Charakteristik nach Richtung und Steigung wie die Führungsrillen hat das Gewinde des Gewindebolzens B bzw. das mit dem Gewindebolzen B zusammenarbeitende Innengewinde IG der Seilrolle SR. Das Seil selbst ist an einer Stelle über ein Klemmstück K fest mit der aus thermoplastischen Kunststoff bestehenden Seilrolle SR fest aber lösbar verbunden.The rope pulley has guide grooves FR for receiving the rope S, which run left-handed in the example shown. The same characteristics in terms of direction and pitch as the guide grooves have the thread of the threaded bolt B or the internal thread IG of the rope pulley SR that cooperates with the threaded bolt B. The rope itself is firmly connected at one point via a clamping piece K to the rope pulley SR, which is made of thermoplastic, but is releasable.

Bei Betätigung des Motors M, um den Schieber z.B. aus der dargestellten Position nach links zu bewegen, wickelt sich der eine Seilabschnitt SA, der mit dem Fühlelement F verbunden ist, von der Seilrolle SR ab und der andere Seilabschnitt SB, der mit dem Schieber SH verbunden ist, auf die Seilrolle auf und zwar exakt in den Führungsrillen FR. Durch diese Bewegung wird beim Aufwickeln des Seilabschnittes SB in Folge des Innengewindes IG des Gewindebolzens B die Seilrolle SR nach oben wegbewegt, wobei die Gewindeneigung und der Umfang der Seilrolle SR so abgestimmt ist, daß das Seil S durch die Durchgangsöffnung Do der Abstreifkammer AK immer geradelinig verläuft. Dadurch kann es zu keinem winkeligen Versatz des Seiles zwischen der Seilrolle SR und der Durchgangsöffnung Do des Seilabschnittes SB kommen. Daraus resultiert ist ein vollständig dichter Abschluß der Abstreifkammer AK durch die Dichtung D. Weiters kann durch die Führungsrillen FR das Seil und damit der Schieber SH sehr exakt positioniert werden. Eventuell doch an dem Seil anhaftender Toner der sich in den Führungsrillen ablagern könnte, wird mit Hilfe von zwei Abschabkanten AS entfernt, die mit ihren Spitzen ASK in die Führungsrillen eingreifen. Eine derartige Abschabekante AS entfernt befindet sich auch im Bereich der Umlenkrolle U. Die Hin-und Herbewegung wird in hier nicht im einzelnen dargestellter Weise dadurch gesteuert, daß das Fühlelement F zwischen zwei die Anschlagposition des Schiebers SH definierenden Schaltern, die mit dem Motor M verbunden sind aktiviert. Um das Seil gespannt zu halten, ist zwischen dem Fühlelement F und dem einen Abschnitt des Seiles S ein Federelement FE angeordnet.When the motor M is actuated to move the slide e.g. To move to the left from the position shown, the one cable section SA, which is connected to the sensing element F, unwinds from the cable pulley SR and the other cable section SB, which is connected to the slider SH, on the cable pulley exactly in the guide grooves FR. As a result of this movement, the cable reel SR is moved upwards when the cable section SB is wound up as a result of the internal thread IG of the threaded bolt B, the thread inclination and the circumference of the cable reel SR being matched such that the cable S is always straight through the through opening Do of the stripping chamber AK runs. As a result, there can be no angular misalignment of the rope between the rope pulley SR and the through opening Do of the rope section SB. This results in a completely tight closure of the stripping chamber AK by the seal D. Furthermore, the rope and thus the slider SH can be positioned very precisely by the guide grooves FR. Any toner sticking to the rope that could be deposited in the guide grooves is removed with the help of two scraping edges AS, which engage with their tips ASK in the guide grooves. Such a scraping edge AS is also located in the region of the deflection roller U. The back and forth movement is not controlled in the manner shown here in detail in that the sensing element F is connected between two switches which define the stop position of the slider SH and which are connected to the motor M. are activated. In order to keep the rope taut, a spring element FE is arranged between the sensing element F and the one section of the rope S.
