Abstract

The applicator system to transfer ink or varnish or water to the forme cylinder of a printing press has a direct or indirect action, with at least one applicator roller (7) and a screen roller (5, 8, 10), working with a transfer roller (16). The screen roller (5, 8, 10) has a drive (12) with a variable speed. During normal working, the surface speed of the screen roller (5, 8, 10) differs from the speeds of the following rollers (7, 16) operating at the machine speed. To increase the flow rate of the transferred medium, the difference is reduced between the screen roller (5, 8, 10) surface speeds and the speeds of the following rollers (7,16).

Description

Zum Auftragen von Medien, wie Farbe, Lack, Wasser etc. werden neben konventionellen Mehrwalzensystemen auch sogenannte Kurzauftragwerke mit wenig Walzen verwendet (DE 43 44 084 C1).
Die Kurzauftragwerke enthalten zum Auftragen der Medien auf einen Formzylinder eine Rasterwalze mit Kammerrakel, wobei die Rasterwalze entweder direkt oder indirekt auf eine Auftragwalze bzw. über eine Auftragwalze unter Zwischenschaltung mindestens einer Übertragungswalze mit dem Formzylinder in Wirkverbindung steht.
Zur Veränderung der optischen Dichte auf dem Druckbogen ist es bekannt (US 44 45 433), 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 Umfangsgeschwindigkeistverhältnisses in der Praxis keinerlei Effekt und erfordert Getriebe mit großem Stellbereich.
Eine Variation der zu übertragenden Medienmenge ist damit weiterhin nur über einen Austausch der Rasterwalze möglich, d.h. Ersatz der verwendeten Rasterwalze durch eine Rasterwalze mit höherem oder niedrigerem Schöpfvolumen.In addition to conventional multi-roller systems, so-called short application units with few rollers are used to apply media, such as paint, lacquer, water, etc. (DE 43 44 084 C1).
The short applicator units contain an anilox roller with a chambered doctor blade for applying the media to a forme cylinder, the anilox roller being operatively connected to the forme cylinder either directly or indirectly on an applicator roller or via an applicator roller with the interposition of at least one transfer roller.
To change the optical density on the printed sheet, it is known (US Pat. No. 4,445,433) that the peripheral speed ratio between an anilox roller and an application roller is from 1: 1 to 3: 1 or 1: 3, preferably to 2: 1 or 1: 2 to change.
This change has no effect in practice due to the incorrectly selected circumferential speed ratio and requires gear units with a large adjustment range.
A variation of the amount of media 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.

In Fig. 1 ist das Walzenschemata eines Kurzauftragwerkes (Aniloxtechnik) einer Bogendruckmaschine dargestellt. Das Walzenschemata zeigt einen Druckzylinder 1 mit Greifersystemen 2, einen Offsetzylinder 3 und einen Formzylinder 4. In Fig. 1 is the roll diagrams of a short application unit (anilox technique) of a sheet printing machine shown. The roller diagram shows a pressure cylinder 1 with gripper systems 2, an offset cylinder 3 and a forme cylinder 4.

Dem Formzylinder 4 ist nach einer ersten Variante eine dritte Rasterwalze 5 mit einer dritten Kammerrakel 6 zugeordnet (gestrichelte Darstellung). Der dritten Rasterwalze 5 ist dabei ein drehzahlvariabler Antrieb 12 zugeordnet.According to a first variant, the forme cylinder 4 is a third anilox roller 5 with a third Chamber doctor blade 6 assigned (dashed line). The third anilox roller 5 is one Variable-speed drive 12 assigned.

Nach einer zweiten Variante (ausgezogene Darstellung) ist dem Formzylinder 4 indirekt über eine Auftragswalze 7 zum Farbauftrag eine erste Rasterwalze 8 mit einer ersten Kammerrakel 9 und zum Feuchtmittelauftrag eine zweite Rasterwalze 10 mit einer zweiten Kammerrakel 11 zugeordnet. Dabei ist den Rasterwalzen 8; 10 jeweils ein drehzahlvariabler Antrieb 12 zugeordnet.
Zwischen der Auftragwalze 7 und den Rasterwalzen 8; 10 kann jeweils eine Übertragungswalze 16 angeordnet werden. In diesem Fall ist entweder den Rasterwalzen 8; 10 oder den Übertragungswalzen 16 ein drehzahlvariabler Antrieb 12 zugeordnet (Fig. 3).According to a second variant (solid representation), the forme cylinder 4 is indirectly assigned a first anilox roller 8 with a first chamber doctor blade 9 via an application roller 7 and a second anilox roller 10 with a second chamber doctor blade 11 for dampening solution application. The anilox rollers 8; 10 each assigned a variable-speed drive 12.
Between the application roller 7 and the anilox rollers 8; 10, a transfer roller 16 can be arranged in each case. In this case, either the anilox rollers 8; 10 or the transfer rollers 16 assigned a variable-speed drive 12 (Fig. 3).

Der drehzahlvariable Antrieb 12 ist als Eigenantrieb, beispielsweise als Motor ausgebildet Der Antrieb kann auch (Fig. 3) durch Eingliederung des Antriebszahnrades 13 der Rasterwalze 5; 8; 10 oder Übertragungswalze 16 in den Antriebsräderzug 14 der Druckmaschine und Zwischenschaltung eines drehzahlsteuernden Wandlungselementes 15 zwischen Antriebszahnrad 13 und Rasterwalze 5; 8; 10 bzw. Übertragungswalze 16 erfolgen. Als Wandlungselement 15 sind Bremsen, Kupplungen, Getriebe etc. anwendbar.The variable-speed drive 12 is designed as a self-drive, for example as a motor The drive can also (Fig. 3) by incorporating the drive gear 13 of the anilox roller 5; 8th; 10 or transfer roller 16 in the drive wheel train 14 of the printing press and interposition of a speed-controlling conversion element 15 between the drive gear 13 and anilox roller 5; 8th; 10 or transfer roller 16 take place. As a change element 15 brakes, clutches, gears, etc. can be used.

Die Rasterwalze 5; 8; 10 kann im Drehrichtungs-Gleichlaufbetrieb (durch Drehrichtungspfeil in Fig. 1 angedeutet) arbeiten, d.h. die Rasterwalze und die nachgeordnete Walze haben im Berührungspunkt gleiche Drehrichtung.
Nach einer Variante arbeitet die Rasterwalze 5; 8; 10 im Reversebetrieb (durch Doppelpfeil in Fig. 1 angedeutet); d.h. die Rasterwalze und die nachgeordnete Walze haben im Berührungspunkt unterschiedliche Drehrichtung.The anilox roller 5; 8th; 10 can work in the direction of rotation synchronous operation (indicated by the direction of rotation arrow in FIG. 1), ie the anilox roller and the downstream roller have the same direction of rotation at the point of contact.
According to a variant, the anilox roller 5 works; 8th; 10 in reverse operation (indicated by double arrow in Fig. 1); ie the anilox roller and the downstream roller have different directions of rotation at the point of contact.

Die Menge des zu übertragenden Mediums (Übertragungsrate v0) wird durch die Umfangsgeschwindigkeitsdifferenz vdiff der Rasterwalze bzw. Übertragungswalze in Relation zu der 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 peripheral speed difference v diff of the anilox roller or transfer roller in relation to the downstream roller.
The transfer diagram for the medium is shown in FIG. 2. The diagram shows the transfer 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 der Erfindung wird das Kurzauftragwerk im Normalbetrieb im auf- oder absteigenden Kurvenbereich betrieben (in Fig. 2 durch starke Linien gekennzeichnet), d.h. es ist eine positive oder negative Umfangsgeschwindigkeitsdifferenz zwischen Rasterwalze oder Übertragungswalze und nachgeordneter Walze vorhanden.
Soll die Übertragungsrate v0 erhöht werden, wird die Umfangsgeschwindigkeitsdifferenz verringert, die Verringerung der Umfangsgeschwindigkeitsdifferenz erfolgt maximal bis zum Wert Eins.
Die Übertragungsrate v0 zwischen Rasterwalze und nachgeordneter Walze, d.h. Auftragwalze, Formzylinder oder Übertragungswalze wird durch eine nur geringfügige Veränderung der Umfangsgeschwindigkeit der Rasterwalze bzw. Übertragungswalze zur nachgeordneten Walze und damit Schaffung einer minimalen prozentualen Umfangsgeschwindigkeitsdifferenz vdiff verändert. 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 der optischen Dichte auf dem Druckbogen möglich. According to the invention, the short application unit is operated in normal operation in the ascending or descending curve area (indicated by thick lines in FIG. 2), ie there is a positive or negative circumferential speed difference between the anilox roller or transfer roller and the downstream roller.
If the transmission rate v 0 is to be increased, the circumferential speed difference is reduced and the circumferential speed difference is reduced to a maximum of one.
The transmission 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 percentage difference in peripheral speed 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 the optical density on the printed sheet is only possible in this minimum range.
