Description

Die Erfindung betrifft eine Einrichtung zum wahlweisen Reinigen mehrerer Zylinder des Druckwerks einer Bogendruckmaschine, die vorzugsweise in Dreizylinderbauweise ausgeführt ist, bestehend aus einer durch Verschieben entlang einer Führungsbahn wahlweise an jeweils einen Zylinder anstellbaren Reinigungsvorrichtung.The invention relates to a device for the optional cleaning of several cylinders the printing unit of a sheet-fed printing press, preferably in a three-cylinder design is made up of one by moving along one Guideway optionally on a cylinder adjustable cleaning device.

Aus der DE 195 12 241 C2 ist eine derartige Einrichtung bekannt. Die Reinigungsvorrichtung wird beidseitig in einer Führungsbahn, welche in den den Zylinderoberflächen zugeordneten Abschnitten äquidistant oder nahezu äquidistant zu diesen verlaufen, verschoben und so den zu reinigenden Oberflächen angenähert. Dem Verlauf der Führungsbahnen folgend ist diesen eine Verzahnung zugeordnet, in welche in der Reinigungsvorrichtung gelagerte Antriebsräder eingreifen. Die Antriebsräder werden mittels eines der Reinigungsvorrichtung zugeordneten Antriebs angetrieben und so die Reinigungsvorrichtung dem jeweils zu reinigenden Zylinder zugeordnet. Nachteilig bei dieser Einrichtung sind der zur Realisierung erforderliche hohe Fertigungsaufwand, der hohe Verschleiß sowie Ungenauigkeiten in der Positionierung der Reinigungsvorrichtung an den Zylindern.Such a device is known from DE 195 12 241 C2. The cleaning device is on both sides in a guideway, which in the cylinder surfaces assigned sections equidistant or almost equidistant run to these, shifted and thus approximated to the surfaces to be cleaned. Following the course of the guideways, a toothing is assigned to them, into which drive wheels mounted in the cleaning device engage. The drive wheels are assigned to the cleaning device by means of one Drive driven and so the cleaning device to be cleaned Assigned cylinder. A disadvantage of this device is the high manufacturing effort required to implement it, the high wear and inaccuracies in positioning the cleaning device on the cylinders.

Aus der DE 42 09 642 A1 ist weiterhin eine Reinigungseinrichtung bekannt, bei der eine an sich bekannte Reinigungsvorrichtung nach dem Tuchtyp um eine Längsachse, die parallel zu den Zylindern verläuft und nahezu gleiche Abstände zu diesen aufweist, drehbar angeordnet ist und durch Verdrehen wahlweise einem Druck- oder Gummituchzylinder zugeordnet werden kann. Durch Beaufschlagen eines elastischen Andrückelementes mittels Druckluft wird das Reinigungstuch in Kontakt mit der zu reinigenden Zylinderoberfläche gebracht. In der einen Druckwerkwand ist der Antrieb für das Verdrehen der Reinigungsvorrichtung vorgesehen, während in der anderen Druckwerkwand die Arbeitsmittel für den Tuchvorschub angeordnet sind.
Diese Reinigungseinrichtung kann lediglich zum Reinigen von zwei Zylindern in Druckwerken nach der Dreizylinderbauweise Verwendung finden. Nachteilig ist außerdem, dass die Reinigungsvorrichtung durch ihre Anordnung auf einer zentralen Schwenkwelle die Zugänglichkeit zu den Zylindern behindert. From DE 42 09 642 A1 a cleaning device is also known, in which a cleaning device known per se according to the type of cloth is arranged to be rotatable about a longitudinal axis, which runs parallel to the cylinders and has almost the same distances from them, and optionally by rotating a pressure - or blanket cylinder can be assigned. By applying pressure to an elastic pressure element, the cleaning cloth is brought into contact with the cylinder surface to be cleaned. The drive for rotating the cleaning device is provided in one printing unit wall, while the working means for the cloth feed are arranged in the other printing unit wall.
This cleaning device can only be used for cleaning two cylinders in printing units based on the three-cylinder design. Another disadvantage is that the cleaning device, because of its arrangement on a central pivot shaft, impedes access to the cylinders.
