Abstract

To vary the flow rate of a transferred medium at a printing press, such as ink or varnish or water, a controlled speed is applied to vary the relative rotating surface speeds between the screen roller (5) or transfer roller between it and the applicator roller (7). The variation in the percentage surface speed ratio is 0.970-1.015. The variation can be in a positive or a negative direction.

Description

Die Erfindung betrifft ein an Druckmaschinen anwendbares Verfahren zur Beeinflussung der Übertragungsrate von Medien, wie Farbe, Wasser oder Lack.The invention relates to a method applicable to printing machines for influencing the Transfer rate of media such as paint, water or paint.

Zum Übertragen von Farbe, Lack etc. sind Zufuhrsysteme mit einer mit einem Kammerrakel zusammenwirkenden Rasterwalze und mindestens einer mit der Rasterwalze und einem Formzylinder zusammenwirkenden Übertragungswalze bekannt (DE 4344084 C1).
Die Rasterwalze ist dabei mit dem Antriebsräderzug der Druckmaschine verbunden und rotiert mit der nachgeordneten Walze mit gleicher Umfangsgeschwindigkeit.
For the transfer of paint, lacquer, etc., supply systems are known with an anilox roller which interacts with a chambered doctor blade and at least one transfer roller which interacts with the anilox roller and a forme cylinder (DE 4344084 C1).
The anilox roller is connected to the drive wheel train of the printing press and rotates with the downstream roller at the same peripheral speed.

Zur Veränderung der optischen Dichte auf dem Druckbogen ist es bekannt ( US 4445433 ), das Umfangsgeschwindigkeitsverhältnis zwischen einer Aniloxwalze und einer Auftragwalze von 1:1 auf 3:1 bzw 1:3, vorzugsweise auf 2:1 bzw.1:2 zu ändern.
Diese Anderung erbringt auf Grund des falsch gewählten Umfangsgeschwindigkeitsverhältnisses in der Praxis keinerlei Effekt und erfordert Getriebe mit großem Stellbereich.
Eine Variation der zu übertragenden Menge von Medium ist damit weiterhin nur über einen Austausch der Rasterwalze möglich, d. h. Ersatz der verwendeten Rasterwalze durch eine Rasterwalze mit höherem oder niedrigerem Schöpfvolumen.
Des Weiteren tritt bei niedrigen Maschinendrehzahlen der Nachteil auf, dass die Übertragungsrate des Mediums (Farbe, Lack etc.) relativ groß ist, es zu einer Überdosierung kommt und damit beim Farbauftrag die Dichtewerte der Druckerzeugnisse negativ beeinflußt werden.
To change the optical density on the printed sheet, it is known (US 4445433) to change the peripheral speed ratio between an anilox roller and an application roller from 1: 1 to 3: 1 or 1: 3, preferably to 2: 1 or 1: 2.
Due to the incorrectly selected peripheral speed ratio, this change has no effect in practice and requires gear units with a large adjustment range.
A variation of the amount of medium to be transferred is therefore still only possible by exchanging the anilox roller, ie replacing the anilox roller used with an anilox roller with a higher or lower scooping volume.
Furthermore, at low machine speeds, there is the disadvantage that the transfer rate of the medium (ink, varnish, etc.) is relatively high, there is an overdosing and thus the density values of the printed products are negatively influenced during ink application.

Aufgabe der Erfindung ist die Schaffung eines Verfahrens zur wirksamen Beeinflussung der Übertragungsrate des von einem Kammerrakelsystem - Rasterwalze / Kammerrakel - bereitgestellten Mediums ohne großen Aufwand.The object of the invention is to provide a method for effectively influencing the Transfer rate of that provided by a chambered doctor blade system - anilox roller / chambered doctor blade Medium without much effort.

Erfindungsgemäß wird die Aufgabe durch den ersten Patentanspruch gelöst, zweckmäßige Ausgestaltungen sind in den Unteransprüchen offenbart. According to the invention the object is achieved by the first claim, expedient embodiments are disclosed in the subclaims.

Nachfolgend wird das erfindundgemäße Verfahren an einem Ausführungsbeispiel näher erläutert.The method according to the invention is explained in more detail below using an exemplary embodiment.

Die Menge des zu übertragenden Mediums (Übertragungsrate v0) wird durch die Umfangsgeschwindigkeitsdifferenz vdiff einer Rasterwalze bzw. einer Übertragungswalze in Relation zu einer nachgeordneten Walze bestimmt.
Das Übertragungsdiagramm für das Medium ist in Fig. 2 dargestellt. Das Diagramm zeigt die Übertragungsrate in Bezug auf die prozentuale Umfangsgeschwindigkeitsdifferenz vdiff, wobei eine prozentuale Umfangsgeschwindigkeitsdifferenz Eins gleiche Umfangsgeschwindigkeit zwischen Rasterwalze und nachgeordneter Walze bedeutet.
The amount of the medium to be transferred (transfer rate v 0 ) is determined by the circumferential speed difference v diff of an anilox roller or a transfer roller in relation to a downstream roller.
The transmission diagram for the medium is shown in Fig. 2. The diagram shows the transmission rate in relation to the percentage circumferential speed difference v diff , wherein a percentage circumferential speed difference one means the same circumferential speed between the anilox roller and the downstream roller.

Gemäß dem Verfahren wird die Übertragungsrate v0 zwischen Rasterwalze und nachgeordneter Walze, d.h. Auftragwalze, Formzylinder oder Übertragungswalze durch eine nur geringfügige Veränderung der Umfangsgeschwindigkeit der Rasterwalze bzw. Übertragungswalze zur nachgeordneten Walze und damit Schaffüng einer minimalen Umfangsgeschwindigkeitsdifferenz vdiff verandert. Der Bereich der prozentualen Umfangsgeschwindigkeitsänderung zwischen Rasterwalze oder Übertragungswalze und nachgeordneter Walze reicht von 0,970 bis 1,015. Nur in diesem Minimalbereich ist eine wirksame Änderung der Übertragungsrate und damit breispielsweisebei der Farbübertragung der optischen Dichte auf dem Druckbogen möglich.
Die Umfangsgeschwindigkeitsänderung kann in positiver oder negativer Richtung, d. h. als Umfangsgeschwindigkeitsverringerung oder als Umfangsgeschwindigkeitserhöhung erfolgen.
Damit sind mehrere Betriebsvarianten möglich. Nach einer ersten Variante wird vom ersten Betriebspunkt B1 - Umfangsgeschwindigkeitsdifferenz Eins, d. h. Gleichlauf - die Übertragungsrate v0 durch Schaffung einer Umfangsgeschwindigkeitsdifferenz verringert.
According to the method, the transfer rate v 0 between anilox roller and downstream roller, ie applicator roller, forme cylinder or transfer roller is changed by only a slight change in the peripheral speed of the anilox roller or transfer roller to the downstream roller and thus creating a minimal peripheral speed difference v diff . The range of percentage change in peripheral speed between anilox roller or transfer roller and downstream roller ranges from 0.970 to 1.015. An effective change in the transmission rate and thus, for example, in the color transmission of the optical density on the printed sheet is only possible in this minimal range.
The change in peripheral speed can take place in a positive or negative direction, ie as a reduction in peripheral speed or as an increase in peripheral speed.
This means that several operating options are possible. According to a first variant, the transmission rate v 0 is reduced from the first operating point B 1 - circumferential speed difference one, ie synchronism - by creating a circumferential speed difference.

Diese Variante läßt sich auch in einen Regelkreis einbeziehen. Bei einer Verringerung bzw. geringen Maschinendrehzahl wird die Umfangsgeschwindigkeitsdifferenz vdiff vergrößert und damit, um ein Überangebot an Farbe zu vermeiden, die Übertragungsrate v0 verringert.This variant can also be included in a control loop. With a reduction or low engine speed, the circumferential speed difference v diff is increased and, in order to avoid an oversupply of color, the transmission rate v 0 is reduced.

Nach einer zweiten Variante wird die Druckmaschine im Normalfall im zweiten Betriebspunkt B2, der auf dem an- oder absteigenden Ast der Kurve (Fig. 2) liegt, betrieben. Eine Verringerung der Umfangsgeschwindigkeitsdifferenz vdiff in Richtung Eins, d. h. Gleichlauf, erbringt eine Erhöhung der Übertragungsrate v0.According to a second variant, the printing press is normally operated at the second operating point B 2 , which lies on the ascending or descending branch of the curve (FIG. 2). A reduction in the circumferential speed difference v diff in the direction of one, ie synchronous operation, results in an increase in the transmission rate v 0 .

In Fig. 1 ist das Walzenschemata eines Kurzauftragwerkes (Aniloxtechnik) einer Bogendruckmaschine dargestellt. Das erfindungsgemäße Verfahren ist an diesem Kurzauftragwerk anwendbar. Das Walzenschemata zeigt einen Druckzylinder 1 mit Greifersystemen 2, einen Offsetzylinder 3 und einen Formzylinder 4. Dem Formzylinder 4 ist indirekt über eine Auftragwalze 7 zum Farbauftrag eine Rasterwalze 5 mit einem Kammerrakel 6 zugeordnet. Dabei ist der Rasterwalze 5 ein drehzahlvariabler Antrieb 8 zugeordnet.
Zwischen der Auftragwalze 7 und der Rasterwalze 5 kann eine Übertragungswalze angeordnet werden. In diesem Fall ist entweder der Rasterwalze 5 oder der Übertragungswalze der drehzahlvariable Antrieb 8 zugeordnet.
In Fig. 1, the roller diagrams of a short application unit (anilox technique) of a sheet-fed printing machine is shown. The method according to the invention can be applied to this short application. The roller diagram shows a printing cylinder 1 with gripper systems 2, an offset cylinder 3 and a forme cylinder 4. The anilox roller 5 with a chambered doctor blade 6 is indirectly assigned to the forme cylinder 4 via an application roller 7 for ink application. The anilox roller 5 is assigned a variable-speed drive 8.
A transfer roller can be arranged between the application roller 7 and the anilox roller 5. In this case, either the anilox roller 5 or the transfer roller of the variable-speed drive 8 is assigned.

Der drehzahlvariable Antrieb 8 ist als Eigenantrieb, beispielsweise als Motor ausgebildet. Der Antrieb kann auch durch Eingliederung des Antriebszahnrades der Rasterwalze 5 oder der Übertragungswalze in den Antriebsräderzug der Druckmaschine und Zwischenschaltung eines drehzahlsteuernden Wandlungselementes zwischen Antriebszahnrad und Rasterwalze 5 bzw. Übertragungswalze erfolgen. Als Wandlungselement für die minimal zu realisierende Umfangsgeschwindigkeitsdifferenz sind sogar Bremsen, Kupplungen etc. anwendbar. The variable-speed drive 8 is designed as a self-drive, for example as a motor. The Drive can also by incorporating the drive gear of the anilox roller 5 or the transfer roller in the drive wheel train of the printing press and the interposition of a speed-controlling Conversion element between the drive gear and anilox roller 5 or transfer roller respectively. As a conversion element for the minimal circumferential speed difference to be realized brakes, clutches, etc. can even be used.

Die Rasterwalze 5 kann im Drehrichtungs-Gleichlaufbetrieb (durch Drehrichtungspfeil in Fig. 1 angedeutet) arbeiten, d. h. die Rasterwalze und die nachgeordnete Walze haben im Berührungspunkt gleiche Drehrichtung.The anilox roller 5 can in the direction of rotation synchronous operation (by direction arrow in Fig. 1st indicated) work, d. H. the anilox roller and the downstream roller have at the point of contact same direction of rotation.

Nach einer Variante arbeitet die Rasterwalze 5 im Reversebetrieb (durch Doppelpfeil in Fig. 1 angedeutet); d. h. die Rasterwalze und die nachgeordnete Walze haben im Berührungspunkt unterschiedliche Drehrichtung. According to a variant, the anilox roller 5 works in reverse mode (by double arrow in FIG. 1 indicated); d. H. the anilox roller and the downstream roller have different points of contact Direction of rotation.
