Description
Die Erfindung betrifft ein Kurzauftragwerk zum Auftragen von Medien auf einen Formzylinder von Druckmaschinen mit einer dem Formzylinder direkt oder indirekt über mindestens eine Auftragwalze zugeordneten Rasterwalze mit Kammerrakel, wobei der Rasterwalze ein drehzahlvariabler Antrieb zugeordnet ist.The invention relates to a short application unit for applying media to a forme cylinder of printing presses with a forme cylinder directly or indirectly via at least an anilox roller associated with a doctor blade, the anilox roller a variable speed drive is assigned.
Zum Auftragen von Medien, wie Farbe, Lack, Wasser etc. werden neben konventionellen Mehrwalzensystemen auch sogenannte Kurzauftragwerke mit wenig Walzen verwendet (DE 4344084 C1).In addition to conventional ones, media such as paint, varnish, water etc. are applied Multi-roller systems also use so-called short-coating units with few rollers (DE 4344084 C1).
Die Kurzauftragwerke enthalten zum Auftragen der Medien auf einen Formzylinder eine Rasterwalze mit Kammerrakel, wobei die Rasterwalze entweder direkt oder indirekt über eine Auftragwalze bzw. über eine Auftragwalze unter Zwischenschaltung mindestens einer Übertragungswalze mit dem Formzylinder in Wirkverbindung steht.The short application units contain an anilox roller to apply the media to a forme cylinder with chambered doctor blade, the anilox roller either directly or indirectly via an applicator roller or via an application roller with the interposition of at least one transfer roller is in operative connection with the forme cylinder.
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.To change the optical density on the printed sheet, it is known (US 4445433) that Circumferential speed ratio between an anilox roll and an application roll of Change 1: 1 to 3: 1 or 1: 3, preferably to 2: 1 or 1: 2. This change brings about In practice, no effect due to the incorrectly selected peripheral speed ratio and requires gear units with a large adjustment range.
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.A variation in the amount of media to be transferred is still only possible through an exchange the anilox roller possible, i.e. Replacement of the anilox roller used by an anilox roller with higher or lower scooping volume.
Aus EP 0796 733 A3 ist eine Flexodruckmaschine mit einem Kammerrakel/Rasterwalzen-System bekannt. Diese Einrichtung wird im Normalbetrieb so gefahren, dass die Geschwindigkeit der Rasterwalze mit der Geschwindigkeit der nachgeordneten Druckwalze gleich ist.EP 0796 733 A3 describes a flexographic printing machine with a chambered doctor blade / anilox roller system known. This device is operated in normal operation so that the speed the anilox roller at the speed of the downstream printing roller is equal to.
In der US 5 113 761 wird ein Farbauftragwerk mit einer Tauchwalze und einer Übertragungswalze beschrieben. Diese Einrichtung weist kein Kammerrakel/Rasterwalzen-System auf. Aus dieser Druckschrift ist entnehmbar, dass bei Erhöhung der Geschwindigkeif der Übertragungswalze die Relativbewegung zur Oberfläche der Tauchwalze steigt und somit die Menge der zu übertragenden Farbe eine Tendenz zum Steigen hat.In US 5 113 761 an inking unit with an immersion roller and a transfer roller described. This device does not have a chambered doctor blade / anilox roller system on. From this document it can be seen that when the speed increases the transfer roller increases the relative movement to the surface of the dip roller and thus the amount of color to be transferred has a tendency to increase.

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.The
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.According to a variant, the
Die Menge des zu übertragenden Medium (Übertragungsrate v0) wird durch die Umfangsgeschwindigkeitsdifferenz vdiff der Rasterwalze bzw. Übertragungswalze in Relation zu der nachgeordneten Walze bestimmt.The amount of the medium to be transferred (transfer rate v 0 ) is determined by the circumferential speed difference v diff of the anilox roller or transfer roller in relation to the downstream roller.
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 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 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.According to the invention, the short application unit is in ascending or descending normal operation Curve area operated (indicated by strong lines in Fig. 2), d. H. it is a positive one or negative peripheral speed difference between anilox roller or transfer roller and downstream roller available.
Soll die Übertragungsrate v0 erhöht werden, wird die Umfangsgeschwindigkeitsdifferenz verringert, die Verringerung der Umfangsgeschwindigkeitsdifferenz erfolgt maximal bis zum Wert eins. 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.
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. 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 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.
