Abstract
Verfahren zum Vermeiden von Schwingungen in Bogendruckmaschinen mit einem Gegendruckzylinder, dem zur Übertragung eines Druckbildes auf einen Bogen mindestens ein Gummizylinder zugeordnet ist, der mit dem Gegendruckzylinder einen Druckspalt bildet, wobei der Achsabstand zwischen dem Gegendruckzylinder und dem Gummizylinder zur Anpassung an die zur Verarbeitung gelangende Materialdicke durch eine Druckbeistellung veränderbar ausgeführt ist, dadurch gekennzeichnet, dass nach dem Aufbringen des Druckbildes auf den Bogen (24) der Achsabstand vergrößert und nachdem ein Bogenende (24.1) des Bogens (24) den Druckspalt (22) verlassen hat, der Achsabstand auf den ursprüngliche Achsabstand zurückgestellt wird.A method for avoiding vibrations in sheet-fed presses with a counter-pressure cylinder, which is assigned to transmit a printed image on a sheet at least one blanket cylinder which forms a pressure nip with the impression cylinder, wherein the center distance between the impression cylinder and the blanket cylinder to adapt to the material thickness to be processed executed by a Druckbeistellung changeable, characterized in that after the application of the printed image on the sheet (24) increases the axial distance and after one end of the sheet (24.1) of the sheet (24) has left the printing nip (22), the axial distance to the original Axle distance is reset.
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Vermeiden von Schwingungen in Bogendruckmaschinen mit einem Gegendruckzylinder, dem zur Übertragung eines Druckbildes auf einen Bogen mindestens ein Gummizylinder zugeordnet ist, der mit dem Gegendruckzylinder einen Druckspalt bildet, wobei der Achsabstand zwischen dem Gegendruckzylinder und dem Gummizylinder zur Anpassung an die zur Verarbeitung gelangende Materialdicke durch eine Druckbeistellung veränderbar ausgeführt ist.The invention relates to a method and a device for avoiding vibrations in sheet-fed presses with an impression cylinder, which is assigned to transfer a printed image on a sheet at least one blanket cylinder, which forms a pressure gap with the impression cylinder, wherein the center distance between the impression cylinder and the blanket cylinder Adaptation to the processing material thickness is made changeable by a Druckbeistellung.
Eine Einrichtung zum Einstellen des Achsabstandes zwischen einem Gegendruckzylinder und einem Gummizylinder sowie zwischen dem Gummizylinder und einem Plattenzylinder ist aus der
Aufgabe der Erfindung ist es, ein Verfahren und eine Einrichtung zu entwickeln, mit denen eine qualitätsgerechte Verarbeitung unabhängig von der eingestellten Druckpressung möglich ist.The object of the invention is to develop a method and a device with which a quality-appropriate processing is possible regardless of the set pressure pressure.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach den Merkmalen des Anspruchs 1 und eine Einrichtung nach den Merkmalen des Anspruchs 3 gelöst.According to the invention the object is achieved by a method according to the features of claim 1 and a device according to the features of
Durch die erfindungsgemäße Lösung ist es möglich, die zum Übertragen des Druckbildes erforderliche Druckpressung zwischen den zu bedruckenden Bogen und dem Gummizylinder nach der Übertragung des Druckbildes zu reduzieren und damit den beim Herauslaufen des Bogenendes aus dem Druckspalt auftretenden Stoß zu minimieren. Damit werden Schwingungen des Gummizylinders und so Störungen bei der Farbübernahme vom Plattenzylinder vermieden.By the solution according to the invention, it is possible to reduce the pressure required for transferring the print image between the sheet to be printed and the blanket cylinder after the transfer of the printed image and thus minimize the impact occurring when the sheet end emerges from the printing nip. This avoids vibrations of the blanket cylinder and thus disturbances in the ink transfer from the plate cylinder.
