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, lacquer or water in Printing presses.

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 is due to the incorrectly selected peripheral speed ratio
no effect in practice and requires gear units with a large adjustment range.
A variation of the amount of medium to be transferred is still only possible by exchanging the anilox roller; ie replacement of 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.

Aus der Druckschrift EP 0 796 733 A1 ist eine Druckmaschine, vorzugsweise Flexodruckmaschine, mit einem in einem Druckmaschinengestell gelagerten Gegendruckzylinder, der mit einem Antrieb versehen ist, und mit mehreren Druckwerken, von denen jedes aus einer angetriebenen, an den Gegendruckzylinder anstellbaren Druckwalze und aus einer an die Druckwalze anstellbaren Farbauftrags- oder Rasterwalze besteht, die mit einem Spülfarbwerk zusammenwirkt, wobei der Gegendruckzylinder, die Druck- und Rasterwalzen jeweils gleichachsig Zahnräder zu ihrem Antrieb tragen und die Rasterwalzen mit besonderen Weiterlaufantrieben versehen sind, bekannt.
Gemäß dieser Druckschrift ist das Druckwalzenzahnrad durch Parallelverschiebung mit dem Gegendruckzylinderzahnrad kuppelbar und die Rasterwalze mit einem eigenen steuerbaren, geschwindigkeitsvariablen und reversierbaren Antrieb versehen und durch ein Zahnrad mit dem Druckwalzenzahnrad kuppelbar.

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 zusammenwirkende 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. 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 acts 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).
FIG. 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.

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.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 with connected to a drive wheel 7, the roller 3 designed as an application roller 5 is also in Machine frame 6 rotatably mounted and has a gear 8. The drive wheel 7 and that 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 is a the speed of the anilox roller and thus their Circumferential speed changing conversion element 10 is arranged. It is also possible, 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 (Drehzahlerhöhung) oder negativer Richtung (Drehzahlerniedrigung) 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 (speed increase) or negative direction (speed reduction) 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, 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 einem an der Rasterwalze angeordneten ersten Inkrementalgeber 11 und 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. For the targeted change in the speed of the anilox roller in relation to the machine speed, z. B. increase or decrease in speed at low machine speed, is the conversion element 10 part of a control loop, which one with a Anilox roller arranged first incremental encoder 11 and with one on the applicator roller arranged second incremental encoder 12 contains connected control 13. With this last described arrangement it is possible with the reduction in machine speed to reduce the speed of the anilox roller or transfer roller analogously and at the same time by means of the conversion element the speed difference between anilox roller and transfer roller and to reduce the downstream roller. This will overdose counteracted low machine speeds.

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 increase the range of change in the transmission rate, it is possible to use the anilox roller to operate at a higher peripheral speed and through the conversion element Reduce the peripheral speed of the anilox roller.
