Abstract
Description
Die Erfindung betrifft eine Einrichtung zum automatischen Druckplattenwechsel bei einer Bogendruckmaschine mit einer Plattenwechselvorrichtung, die eine einem Plattenzylinder zuordbare Transportwalze aufweist, wobei das Antreiben der Bogendruckmaschine von mindestens einem Hauptmotor über einen Räderzug erfolgt und den Plattenzylindern eine Schaltkupplung sowie ein separater Antrieb zugeordnet ist.The The invention relates to a device for automatic printing plate change in a sheet-fed press with a plate changing device, which has a transport roller which can be assigned to a plate cylinder, wherein the driving of the sheet-fed printing machine of at least one Main engine over a gear train takes place and the plate cylinders a clutch and a separate drive assigned.
Bei
Bogendruckmaschinen, die von mindestens einem Hauptantrieb über einen
Räderzug
angetrieben werden, ist es allgemein bekannt, jedem Druckwerk eine
Plattenwechselvorrichtung zuzuordnen. Diese Plattenwechselvorrichtungen
weisen eine den Plattenzylindern zuordbare Transportwalze auf. Die
Transportwalze wird beim Aufbringen einer neuen Druckplatte an den
Plattenzylinder angestellt, um eine satte Auflage der Platte auf
der Mantelfläche
des Plattenzylinders realisieren zu können. Beim Abführen einer
abgedruckten Druckplatte wird die Transportrolle beabstandet zum
Plattenzylinder positioniert und dient zum Führen des freien Endes der Druckplatte.
Um ein unkontrolliertes Zurückschnellen
der Druckplatte, wenn das hintere Ende durch die Plattenklemm- und
-spanneinrichtung freigegeben wird, von der gesamten Mantelfläche des
Plattenzylinders zu vermeiden, ist der Gummizylinder zum Fördern der
Druckplatte an den Plattenzylinder angestellt (
Aus
der
Bei einer mit einem derartigen Antrieb ausgerüsteten Bogendruckmaschine ist es möglich, gleichzeitig bzw. phasenversetzt zueinander unterschiedliche Prozesse zu realisieren. So ist es z.B. möglich, dass zur Vorbereitung eines neuen Druckauftrages das Wechseln der Druckplatten gleichzeitig mit Waschvorgängen für die Gummizylinder ausgeführt wird. Dazu werden die den einzelnen Plattenzylindern zugeordneten Schaltkupplungen gelöst, so dass die drehfeste Verbindung zwischen den jeweiligen Plattenzylindern und den zugeordneten Zahnrädern aufgehoben ist. Damit sind die Plattenzylinder durch die jeweils zugeordneten Antriebe frei dreh- und positionierbar gegenüber den Gummizylindern und den anderen Zylindern oder Trommeln, wobei die Gummizylinder von den Plattenzylindern abgestellt sind. Durch die den einzelnen Druckwerken zugeordneten Plattenwechselvorrichtungen kann dann der Plattenwechsel ausgeführt werden.at a sheet-fed printing machine equipped with such a drive it possible, at the same time or phase-shifted to realize different processes to each other. So it is e.g. possible, that for the preparation of a new print job, changing the Printing plates is performed simultaneously with washing operations for the rubber cylinder. These are the individual plate cylinders associated clutches solved, so that the rotationally fixed connection between the respective plate cylinders and the associated gears is canceled. Thus, the plate cylinder by the respective assigned drives freely rotatable and positionable with respect to the Rubber cylinders and the other cylinders or drums, the Cylinder rubber from the plate cylinders are parked. By the the individual printing units associated plate changing devices then the plate change can be performed.
Nachteilig ist, da die Gummizylinder von den Plattenzylindern abgestellt sind, dass beim öffnen der hinteren Klemm- und Spanneinrichtung zum Abführen der abgedruckten Druckplatten diese aufgrund ihrer Eigensteifigkeit zurückfedern, wodurch die Gefahr besteht, dass die Druckplatten oder die Gummitücher beschädigt werden. Um das zu vermeiden, sind zusätzlich den Aufwand erhöhende Führungselemente erforderlich, die außerdem Bauraum beanspruchen, der in diesem Bereich nicht zur Verfügung steht.adversely is because the blanket cylinders are offset from the plate cylinders, that when open the rear clamping and tensioning device for discharging the printed printing plates these spring back due to their inherent rigidity, which increases the risk exists that the printing plates or the blankets are damaged. To avoid that, are additionally increasing the effort guide elements required, as well Take up space that is not available in this area.
Aufgabe der Erfindung ist es, eine gattungsgemäße Einrichtung mit geringem Aufwand so zu verändern, dass ein problemloser Plattenwechsel auch bei einem abgestellten Gummizylinder möglich ist.task The invention is a generic device with low To change the effort so that a trouble-free plate change even with a parked Rubber cylinder is possible.
Erfindungsgemäß wird die Aufgabe durch eine Einrichtung nach den Merkmalen des Anspruchs 1 gelöst.According to the invention Task by a device according to the features of the claim 1 solved.
Durch die erfindungsgemäße Lösung ist es möglich, bei einer Bogendruckmaschine mit einem durch einen zusätzlichen Motor unabhängig vom Hauptantrieb antreibbaren Plattenzylinder ohne zusätzliche Mittel die Druckplatte beim Zu- und Abführen so zu führen, dass ein problemloser Plattenwechsel möglich ist.By the solution according to the invention it is possible in a sheet-fed press with one by an additional Engine independent from the main drive drivable plate cylinder without additional Means to guide the pressure plate during feeding and discharging so that a trouble-free plate change is possible.
Die Erfindung wird an einem Ausführungsbeispiel näher erläutert. In den zugehörigen Zeichnungen zeigenThe Invention is based on an embodiment explained in more detail. In the associated Drawings show
