Abstract
Description
Die Erfindung betrifft eine Tintenstrahldruckvorrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to an ink jet printing apparatus according to the preamble of claim 1.
Es sind Tintenstrahldruckvorrichtungen bekannt, die in eine Bogenoffsetdruckmaschine integriert sind, wobei Bogen mit Greifern transportiert werden, die mit Bogentransporttrommeln baulich vereinigt sind. Die Düsen der Tintenstrahldruckvorrichtungen sind auf einen Bogen gerichtet, der auf der Oberfläche einer Bogentransporttrommel gehalten ist. Die Düsen besitzen einen geringen Abstand zum Bogen bzw. zur Mantelfläche der Bogentransporttrommel. Wenn Düsen gereinigt oder sonst wie gewartet werden sollen, wird die Zufuhr von Bogen zur Bogenoffsetdruckmaschine eingestellt und werden die Tintenstrahldruckköpfe von einer Druckposition in eine Reinigungs- bzw. Wartungsposition verfahren oder abgeschwenkt. Derartig ausgebildete Tintenstrahldruckvorrichtungen sind voluminös. Das Verfahren oder Verschwenken in die Reinigungs- oder Wartungsposition und zurück in die Druckposition ist zeitaufwändig. Weil unbenutzte Düsen durch Eintrocknen der Tinte zum Verstopfen neigen, müssen Reinigungsvorgänge regelmäßig durchgeführt werden, um eine hohe Verfügbarkeit der Tintenstrahldruckvorrichtung zu gewährleisten.It are inkjet printing devices known in a sheetfed offset press are integrated, whereby sheets are transported by grippers, which are structurally associated with sheet transport drums. The nozzles of the Inkjet printing devices are directed to a sheet that on the surface a sheet transport drum is held. The nozzles have a small Distance to the bow or to the lateral surface of the sheet transport drum. If nozzles cleaned or otherwise to be maintained, is the supply from sheet to sheetfed offset press set and become the Inkjet printheads from a print position to a cleaning or maintenance position moved or swung. Such formed inkjet printing devices are voluminous. The process or pivoting into the cleaning or maintenance position and back in the printing position is time consuming. Because unused nozzles through Drying of the ink tends to clogging, cleaning operations must be carried out regularly, for a high availability to ensure the inkjet printing device.
Aus
der
Aufgabe der Erfindung ist es, eine Tintenstrahldruckvorrichtung zu entwickeln, die einen geringen Bauraum benötigt und eine hohe Zuverlässigkeit aufweist.task the invention is to develop an ink jet printing apparatus which requires a small space and has high reliability.
Die Aufgabe wird mit einer Tintenstrahldruckvorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object is achieved with an ink jet printing apparatus which having the features of claim 1. Advantageous embodiments emerge from the dependent claims.
Gemäß der Erfindung wird eine Reinigungsvorrichtung für Düsen einer Tintenstrahldruckvorrichtung auf einem Zylinder angeordnet, mit dem zu bedruckende Bogen gefördert werden. Die Reinigungsvorrichtung wird vorzugsweise in einem Kanal des Zylinders angeordnet, in dem zusätzlich ein den Bogen haltendes Greifersystem angeordnet ist.According to the invention is a cleaning device for nozzles of an inkjet printing device arranged on a cylinder, are promoted with the sheet to be printed. The cleaning device is preferably in a channel of the cylinder arranged in addition to a bow holding gripper system is arranged.
Für einen Reinigungsvorgang wird ein Tintenstrahldruckkopf auf die Reinigungsvorrichtung abgesenkt oder die Reinigungsvorrichtung wird aus dem Zylinder ausgefahren. Während dem Reinigen wird der Raum zwischen Tintenstrahldruckkopf und Reinigungsvorrichtung mit einer umlaufenden Dichtung abgedichtet. Die Reinigung des Tintenstrahldruckkopfes kann mit einer Rakel, einer Gummilippe oder einem Vliesoptional mit einer Reinigungsflüssigkeit durchgeführt werden. Überschüssige Tinte kann mittels einer Saugluftquelle abgeführt werden. Bei Nichtgebrauch kann die Reinigungsvorrichtung mit einem Verschluss abgedeckt werden, so dass ein unkontrolliertes Wegschleudern der Tinte verhindert ist.For one Cleaning process is an inkjet printhead on the cleaning device lowered or the cleaning device is extended out of the cylinder. While the cleaning is the space between the inkjet printhead and cleaning device sealed with a circumferential seal. The cleaning of the inkjet printhead Can be with a squeegee, a rubber lip or a fleece optional with a cleaning fluid carried out become. Excess ink can be removed by means of a suction air source. When not in use the cleaning device can be covered with a closure, so that an uncontrolled ejection of the ink prevented is.
Wenn die Reinigungsvorrichtung an einen Gegendruckzylinder einer Offsetdruckmaschine angeordnet ist, kann zum Anfahren der Reinigungsposition der Gegendruckzylinder mit einem Eigenantrieb gekoppelt werden, wobei der Gegendruckzylinder mit einer Kupplung aus dem Antriebsstrang der Offsetdruckmaschine getrennt ist.If the cleaning device to a counter-pressure cylinder of an offset printing machine is arranged, can for approaching the cleaning position of the impression cylinder be coupled with a self-propelled, wherein the impression cylinder with a clutch from the drive train of the offset printing machine is disconnected.
Die Erfindung soll nachstehend anhand eines Ausführungsbeispieles noch näher erläutert werden, es zeigen:The Invention will be explained below with reference to an embodiment in more detail, show it:
