Abstract

To vary the ink delivery rate, at a printing press, a rotary speed converter (10) is between the drive wheel (7) of the screen roller and the screen roller (1), and between the cogwheel (8) of the transfer roller and the transfer roller (14). The speed converter (10) increases or decreases the rotary speed, as a brake or clutch, part of a control circuit, or a variable gearing.

Description

Die Erfindung betrifft ein Übertragungssystem für Medien, wie Farbe, Lack oder Wasser in Druckmaschinen.The invention relates to a transmission system for media such as paint, varnish or water in printing machines.

Zum Übertragen von Farbe, Lack etc. sind Zufuhrsysteme mit einer, mit einer 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 verbunden und rotiert mit Maschinengeschwindigkeit.
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 Änderung erbringt auf Grund des falsch gewählten Umfangsgeschwindigkeitsverhältnisses in der Praxis keinerlei Effekt und erfordert Getriebe mit großem Stellbereich.
Eine Variation der zu übertragenden Menge an 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.
Bei niedrigen Drehzahlen tritt der Nachteil auf, daß die Übertragungsrate des Mediums (Farbe, Lack etc.) relativ groß ist, es zu einer Überdosierung kommt und damit beispielsweise beim Farbauftrag die Dichtewerte der Druckerzeugnisse negativ beeinflußt werden.For the transfer of paint, lacquer, etc., supply systems are known with an anilox roller which interacts with a chamber 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 and rotates at machine speed.
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 .
This change has no effect in practice due to the incorrectly selected peripheral speed ratio 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 by an anilox roller with a higher or lower scooping volume.
At low speeds, there is the disadvantage that the transfer rate of the medium (ink, varnish, etc.) is relatively high, there is an overdosing and thus, for example, the density values of the printed products are negatively influenced during ink application.

Aufgabe der Erfindung ist die Schaffung eines Systems zur Beeinflussung der Übertragungsrate des von einem Rasterwalze/Kammerrakelsystem bereitgestellten Mediums.The object of the invention is to create a system for influencing the transmission rate of the medium provided by an anilox roller / chambered doctor blade system.

Erfindungsgemäß wird die Aufgabe durch die Kennzeichen der Patentansprüche gelöst, zweckmäßige Ausgestaltungen sind in den Unteransprüchen offenbart.According to the invention the object is solved by the characterizing part of the claims, expedient Refinements are disclosed in the subclaims.

Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher erläutert. The invention is explained in more detail below using an exemplary embodiment.

Transmission system

Unter dem Begriff Übertragungssystem werden unterschiedliche Walzenschemata subsumiert, von denen in den Figuren 1 - 4 einige Walzenschemata beispielhaft beschrieben werden.
Das Walzenschemata gemäß Fig. 1 zeigt eine Rasterwalze 1 mit einem Kammerrakel 2 und einer der Rasterwalze 1 nachgeordneten Walze 3. Die Walze 3 fungiert als mit einem Formzylinder 4 zusammenwirkenden Auftragwalze 5. Sind zwischen der Rasterwalze 1 und Auftragswalze 5 Zwischenwalzen angeordnet, fungiert die der Rasterwalze nachgeordnete Walze 3 als Übertragungswalze 14 (Fig. 2).
In Fig. 3 ist ein Walzenschemata dargestellt, bei dem die der Rasterwalze 1 nachgeordnete Auftragwalze 3 als Auftragzylinder 15, der mit einem Formzylinder 4 in Wirkverbindung steht, ausgebildet ist.
In Fig. 4 ist eine Variante dargestellt, bei der die Rasterwalze 1 direkt mit einem Formzylinder 4 in Wirkverbindung steht.
In Fig. 5 ist das Übertragungssystem gemäß dem in Fig. 1 dargestellten Walzenschema dargestellt. Die Rasterwalze 1 ist im Maschinengestell 6 drehbar gelagert. Die Rasterwalze 1 ist mit einem Antriebsrad 7 verbunden, die als Auftragswalze 5 ausgebildete Walze 3 ist ebenfalls im Maschinengestell 6 drehbar gelagert und weist ein Zahnrad 8 auf. Das Antriebsrad 7 und das Zahnrad 8 sind Teil des Antriebsräderzuges 9 der Druckmaschine. Zwischen dem Antriebsrad 7 der Rasterwalze und der Rasterwalze 1 ist ein die Drehzahl der Rasterwalze und damit deren Umfangsgeschwindigkeit veränderndes Wandlungselement 10 angeordnet. Es ist auch möglich, das Wandlungselement 10 der Übertragungswalze 14 (Fig. 2 ) zuzuordnen. Different roller schemes are subsumed under the term transmission system, of which some roller schemes are exemplarily described in FIGS. 1-4.
1 shows an anilox roller 1 with a chamber doctor blade 2 and a roller 3 arranged downstream of the anilox roller 1. The roller 3 functions as an application roller 5 interacting with a forme cylinder 4. If intermediate rollers 5 are arranged between the anilox roller 1 and application roller 5, the roller acts Anilox roller downstream roller 3 as transfer roller 14 (Fig. 2).
3 shows a roller diagram in which the applicator roller 3 arranged downstream of the anilox roller 1 is designed as an applicator cylinder 15 which is operatively connected to a forme cylinder 4.
4 shows a variant in which the anilox roller 1 is operatively connected directly to a forme cylinder 4.
FIG. 5 shows the transmission system according to the roller diagram shown in FIG. 1. The anilox roller 1 is rotatably mounted in the machine frame 6. The anilox roller 1 is connected to a drive wheel 7, the roller 3 designed as an application roller 5 is also rotatably mounted in the machine frame 6 and has a gear wheel 8. The drive wheel 7 and the gear 8 are part of the drive wheel train 9 of the printing press. Between the drive wheel 7 of the anilox roller and the anilox roller 1 there is a conversion element 10 which changes the speed of the anilox roller and thus its peripheral speed. It is also possible to assign the conversion element 10 to the transfer roller 14 (FIG. 2).

Durch die Veränderung der Drehzahl der Rasterwalze 1 bzw. Übertragungswalze in Relation zu der Auftragwalze 5 wird das Gleichlaufverhalten verändert, damit auch die Übertragungsrate und bei der Übertragung von Farbe auch die Dichtewerte derselben auf den Druckbogen.
Eine Abweichung vom Gleichlaufverhalten in positiver Richtung (Drebzahlerhöhung) oder negativer Richtung (Drebzahlerniedrigung) bringt dabei den gleichen Effekt in der Veränderung der Übertragungsrate. Die prozentuale Umfangsgeschwindigkeitsdifferenz zwischen Rasterwalze oder Übertragungswalze und nachgeordneter Walze liegt dabei im Bereich von 0,970 bis 1,015.By changing the speed of the anilox roller 1 or transfer roller in relation to the applicator roller 5, the synchronism behavior is changed, so that the transfer rate and, when ink is transferred, the density values of the same on the printing sheet.
A deviation from the synchronism behavior in the positive direction (increase in the number of revolutions) or negative direction (decrease in the number of revolutions) brings the same effect in changing the transmission rate. The percentage difference in peripheral speed between anilox roller or transfer roller and downstream roller is in the range from 0.970 to 1.015.

Das Wandlungselement 10 ist als Bremse, Kupplung, Getriebe oder Elektromotor ausgebildet, wobei aus Platzgründen die Verwendung einer Kupplung in der Ausbildung als rheologische Kupplung vorteilhaft ist. Die genannten Elemente sind drehzahlsteuer- und -regelbar. Unter rheologischer Kupplung wird eine Fluid-Kupplung verstanden, bei der über ein steuerbares Magnetfeld die Viskosität des Übertragungsfluids und damit die Drehzahl veränderbar ist.The conversion element 10 is designed as a brake, clutch, gearbox or electric motor, for reasons of space, the use of a coupling in training as a rheological Coupling is advantageous. The elements mentioned can be speed controlled and regulated. Under Rheological coupling is understood to be a fluid coupling in which a controllable magnetic field is used the viscosity of the transmission fluid and thus the speed can be changed.

Zu der gezielten Veränderung der Drehzahl der Rasterwalze in Relation zur Maschinengeschwindigkeit, z. B. Erhöhung oder Absenkung der Drehzahl bei geringer Maschinengeschwindigkeit, ist das Wandlungselement 10 Teil eines Regelkreises, welcher eine, mit ihrem an der Rasterwalze angeordneten ersten Inkrementalgeber 11 und einem mit einem an der Auftragwalze angeordneten zweiten Inkrementalgeber 12 verbundene Regelung 13 enthält. Mit dieser zuletzt beschriebenen Anordnung ist es möglich, mit der Verringerung der Maschinengeschwindigkeit die Drehzahl der Rasterwalze oder Übertragungswalze analog zu verringern und gleichzeitig mittels des Wandlungselementes die Drehzahldifferenz zwischen Rasterwalze und Übertragungswalze und nachgeordneter Walze zu verringern. Damit wird einer Überdosierung bei niedrigen Maschinengeschwindigkeiten entgegengewirkt.
Zur Erhöhung des Bereiches der Veränderung der Übertragungsrate ist es möglich, die Rasterwalze mit höherer Umfangsgeschwindigkeit zu betreiben und durch das Wandlungselement die Umfangsgeschwindigkeit der Rasterwalze zu senken. To specifically change the speed of the anilox roller in relation to the machine speed, e.g. B. Increase or decrease in speed at low machine speed, the conversion element 10 is part of a control loop which contains a control 13 connected to its first incremental encoder 11 arranged on the anilox roller and to a control 13 connected to a second incremental encoder arranged on the applicator roller. With this arrangement described last, it is possible to reduce the speed of the anilox roller or transfer roller analogously with the reduction of the machine speed and at the same time to reduce the speed difference between the anilox roller and transfer roller and downstream roller by means of the conversion element. This counteracts overdosing at low machine speeds.
To increase the range of change in the transmission rate, it is possible to operate the anilox roller at a higher peripheral speed and to reduce the peripheral speed of the anilox roller by means of the conversion element.
