Abstract
Description
Die Erfindung betrifft eine Lagerung von Walzen und/oder Zylindern in Druckwerken von Rotationsdruckmaschinen, die zum Bedrucken eines Bedruckstoffes geeignet sind, wobei die Lagerung der Walzen bzw. der Zylinder über ihre Wellenzapfen erfolgt und Mittel zum Ändern des Achsabstandes zwischen mindestens zwei Walzen bzw. Zylindern vorgesehen sind.The The invention relates to a storage of rollers and / or cylinders in Printing units of rotary printing machines used for printing a Printing material are suitable, the storage of the rollers or the cylinder over its shaft journal takes place and means for changing the axial distance between at least two rollers or cylinders are provided.
Aus
der
Die Farbauftragwalze ist in einem Doppelexzenter mit jeweils einer Verstelleinrichtung für eine innere und äußere Exzenterbuchse gelagert. Dadurch ist die Farbauftragwalze im Abstand zum Plattenzylinder und zur Rasterwalze zur Regulierung des Farbtransports verstellbar.The Ink applicator roller is in a double eccentric, each with an adjustment for one inner and outer eccentric bush stored. As a result, the inking roller is at a distance from the plate cylinder and adjustable to the anilox roller for regulating the color transport.
Ein für den Farbtransport stehender Parameter wird durch ein thermoempfindliches Messelement erfasst. Dieser Parameter wird mit einer Sollwertkennlinie, welche die Farbdichte in Abhängigkeit mit diesem Parameter repräsentiert, verglichen. Daraus wird die Differenz zwischen dem Soll-Farbdichtewert und dem Ist-Wert ermittelt und ein Signalverstärker angesteuert, der, der jeweils Steuerwerte für die Verstelleinrichtungen der inneren und äußeren Exzenterbuchse zur voneinander unabhängigen Verdrehung beider ausgibt. Dadurch ist der Achsabstand zwischen der Rasterwalze und der Farbauftragwalze einstellbar und somit die Farbdichte regulierbar.One for the Color transport standing parameter is determined by a thermosensitive Detected measuring element. This parameter comes with a setpoint characteristic curve, which the color density in dependence represented with this parameter, compared. From this, the difference between the target color density value and the actual value is determined and a signal amplifier driven, the, each control values for the adjustment of the inner and outer eccentric bush to each other independent Twist both outputs. As a result, the axial distance between the anilox roller and the inking roller adjustable and thus the Color density adjustable.
Nachteilig ist, dass beim Einsatz von Farbauftragwalzen mit einem größeren Durchmesser das Bedürfnis besteht, wechselbare Bespannungen für die Farbauftragwalzen vorzusehen. Diese werden dann in einem Spannkanal befestigt. Die Oberflächen der Rasterwalze und des Plattenzylinders rollen auf der Oberfläche der Farbauftragwalze ab und durchlaufen auch den Spannkanal. Dadurch kommt es insbesondere bei höheren Geschwindigkeiten zu dynamischen Belastungen des Druckwerkes. Das heißt, es werden Schwingungen generiert, die sich negativ auf die Druckqualität auswirken.adversely is that when using inking rollers with a larger diameter the need consists of providing changeable coverings for the inking rollers. These are then fastened in a clamping channel. The surfaces of the Anilox roller and plate cylinder roll on the surface of the Paint roller off and also go through the clamping channel. Thereby it happens especially at higher levels Speeds to dynamic loads of the printing unit. That is, it will be Generates vibrations that negatively impact print quality.
Zur Vermeidung dieser Schwingungen ist es im Druckmaschinenbau üblich, sogenannte Schmitzringe einzusetzen. Schmitzringe sind als Laufringe ausgebildete Stützele mente, die auf den Zapfen von Zylindern angeordnet sind und die beiden Enden eines Zylinders abstützen, um unerwünschte Zylinderschwingungen zu reduzieren und damit trotz Kanalschlägen einen sauberen Druck zu ermöglichen. Der Durchmesser der Schmitzringe ist so bemessen, dass die an zusammenwirkenden, benachbarten Zylindern angebrachten Schmitzringe aufeinander abrollen. Mit einer Schmitzringanordnung wird somit auch ein definierter Achsenabstand zwischen zwei Druckwerkszylindern eines Rotationsdruckwerkes erzielt.to Avoiding these vibrations, it is common in printing press, so-called Use bearer rings. Bearer rings are designed as races Supporting elements, which are arranged on the pins of cylinders and the two Support the ends of a cylinder, around unwanted To reduce cylinder vibrations and thus despite channel strikes one to allow clean pressure. The diameter of the bearer rings is such that the co-operating, Roll off the bearer rings attached to adjacent cylinders. With a Schmitzringanordnung thus also a defined axis distance achieved between two printing cylinders of a rotary printing unit.
Derartige
Schmitzringe sind zum Beispiel aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lagerung von Walzen und/oder Zylindern in Druckwerken von Rotationsdruckmaschinen zu entwickeln, durch die bei der Veränderung der Lage der Achsen der Walzen und/oder der Zylinder die Laufruhe der betreffenden Walze bzw. des Zylinders aufrecht erhalten und Schwingungen unterdrückt werden.Of the The invention is therefore based on the object, a storage of rollers and / or cylinders in printing units of rotary printing presses develop by which when changing the position of the axes the rollers and / or the cylinder smooth running of the respective roller or the cylinder maintained and vibrations are suppressed.
Erfindungsgemäß wird die Aufgabe durch Lagerung von Walzen in Druckwerken von Rotationsdruckmaschinen mit den Merkmalen des 1. Anspruchs gelöst.According to the invention Task by storage of rolls in printing units of rotary printing machines solved with the features of the first claim.
Die Erfindung hat den Vorteil, dass nunmehr auch bei Walzen und Zylindern, die einen Spannkanal aufweisen, die Nachführung der Druckpressung möglich ist, ohne dass auf eine Stabilisierung des Laufs verzichtet werden muss. Die erfindungsgemäße Lösung stellt einen vollwertigen Ersatz von Schmitzringen bei derartigen Anwendungsfällen dar.The Invention has the advantage that now also with rollers and cylinders, have a clamping channel, the tracking of the pressure is possible, without having to forego a stabilization of the barrel. The solution according to the invention provides a full replacement of Schmitzringen in such applications.
