Abstract
Description
Die vorliegende Erfindung betrifft eine Abdeck- und Reinigungsvorrichtung für einen Druckkopf einer Tintenstrahldruckeinheit gemäß dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Abdeckung und Reinigung eines Druckkopfes.The present invention relates to a capping and cleaning device for a printhead of an ink jet printing unit according to the preamble of claim 1 and to a method for capping and cleaning a printhead.
Tintenstrahldrucker weisen einen Druckkopf auf, der mit einer oder mehreren Düsen ausgestattet ist, durch die zum Bedrucken eines Gegenstands winzige Tropfen einer farbigen Tinte austreten. An dem Druckkopf kommt es nach einiger Zeit zur Anlagerung von Schmutzpartikeln und eingetrockneter Druckfarbe, was zu einer Verstopfung der Düsenöffnungen führen kann. Außerdem beeinträchtigen diese Ablagerungen die Druckqualität der Druckeinheit. Zur Aufrechterhaltung der Funktionsfähigkeit der Druckereinheit sowie einer guten Druckqualität muss die Oberfläche des Druckkopfes daher in regelmäßigen Abständen gereinigt werden.Ink jet printers include a printhead equipped with one or more nozzles through which minute drops of colored ink emerge to print an article. After some time, the print head causes the accumulation of dirt particles and dried ink, which can lead to blockage of the nozzle openings. In addition, these deposits affect the print quality of the printing unit. To maintain the integrity of the printer unit and print quality, the surface of the printhead must be cleaned at regular intervals.
Zur Reinigung des Druckkopfes werden beispielsweise Wischeinrichtungen mit einer Wischlippe verwendet, welche über den Druckkopf bewegt wird. Die sich nach einem solchen Abwischvorgang an der Wischlippe angesammelte Tinte wird über eine Absaugvorrichtung o. ä. von der Wischlippe abgesaugt.For cleaning the print head, for example, wiping devices with a wiper lip are used, which is moved over the print head. The accumulated at such a wiping operation on the wiper lip ink is sucked through a suction device o. Ä. From the wiper lip.
Aufgabe der vorliegenden Erfindung ist es, eine Abdeck- und Reinigungsvorrichtung für einen Druckkopf einer Tintenstrahldruckeinheit bereitzustellen, mit der in einfacher Weise auch ohne Absaugvorrichtung ein störungsfreier Druckbetrieb gewährleistet wird.The object of the present invention is to provide a covering and cleaning device for a print head of an inkjet printing unit, with which a trouble-free printing operation is ensured in a simple manner even without a suction device.
Diese Aufgabe wird durch eine Abdeck- und Reinigungsvorrichtung mit den Merkmalen des Anspruchs 1, sowie durch ein Verfahren zur Abdeckung und Reinigung eines Druckkopfes mit den Merkmalen des Anspruchs 10 gelöst.This object is achieved by a covering and cleaning device with the features of claim 1, and by a method for covering and cleaning a printhead having the features of
Erfindungsgemäß ist die Wischlippe der Abdeck- und Reinigungsvorrichtung über eine Führungsmechanik der Antriebseinheit derart montiert, dass die Wischlippe beim Überfahren des Druckkopfes in einer Reinigungsrichtung den Druckkopf berührt und beim Überfahren des Druckkopfes in einer der Reinigungsrichtung entgegengesetzten Richtung den Druckkopf nicht berührt. Dadurch ist gewährleistet, dass die Wischlippe nur in einer Richtung über den Druckkopf wischt, so dass beispielsweise eine Verschmierung von angetrockneter Tinte durch die Wischlippe verhindert wird.According to the invention, the wiper lip of the covering and cleaning device is mounted via a guide mechanism of the drive unit such that the wiper lip touches the print head when it passes over the print head in a cleaning direction and does not touch the print head when the print head is moved over in a direction opposite to the cleaning direction. This ensures that the wiper lip only wipes over the print head in one direction, so that, for example, smearing of dried-on ink by the wiper lip is prevented.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the dependent claims.
Gemäß einer bevorzugten Ausführungsvariante ist die Wischlippe an einem Bolzen festgelegt, der an einem von der Wischlippe beabstandeten Ende entlang einer Kurvenbahn geführt ist. Dadurch ist eine exakte Führung der Wischlippe entlang ihres Verfahrweges ermöglicht.According to a preferred embodiment, the wiper lip is fixed to a bolt, which is guided at an end remote from the wiper lip along a curved path. This allows an exact guidance of the wiper lip along its travel path.
Gemäß einer weiteren Ausführungsvariante ist in Reinigungsrichtung vor dem Druckkopf eine Abstreifkante vorgesehen, an die die Wischlippe vor dem Überfahren des Druckkopfes abstreifbar ist. Diese Abstreifkante ist gemäß einer bevorzugten Ausführungsvariante schräg zur Reinigungsrichtung und zur Längsachse der Wischlippe ausgerichtet. Dadurch ist die Gegenkraft, die der Verschwenkung der Reinigungseinheit in Reinigungsrichtung entgegenwirkt, im Vergleich zum vollflächigen Auftreffen der Wischlippe gering. Dadurch wird eine kontinuierliche Bewegung über die gesamte Kantenlänge der Abstreifkante gewährleistet, so dass im Bewegungsablauf keine Blockade auftreten kann. Eine schräge Abstreifkante bewirkt außerdem eine Toleranzunabhängigkeit in Bezug auf den Auftreffpunkt der Wischlippe auf der Abstreifkante, was sich kostengünstig in der Herstellung und der Montage einer Einheit auswirkt.According to a further embodiment variant, a wiping edge is provided in the cleaning direction in front of the print head, to which the wiper lip can be wiped before passing over the print head. This wiper edge is oriented obliquely to the cleaning direction and to the longitudinal axis of the wiper lip according to a preferred embodiment variant. As a result, the counterforce, which counteracts the pivoting of the cleaning unit in the cleaning direction, in comparison to the full-surface impact of the wiper lip low. As a result, a continuous movement over the entire edge length of the wiper edge is ensured so that no blockage can occur in the course of movement. An oblique wiper edge also causes a tolerance independence with respect to the point of impact of the wiper lip on the wiper edge, which has a cost effective in the manufacture and assembly of a unit.
