Abstract

Ink chamber for a rotary print machine has an additional intermediate wall between the input ink zone of the ink roller and the first intermediate wall so that a further chamber is generated between the two intermediate walls.

Description

Die Erfindung betrifft eine Rakelkammer für Rotationsdruckmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a doctor blade chamber for rotary printing presses the preamble of claim 1.

Solche Rakelkammern finden vor allem in Flexodruckmaschinen Verwendung. So zeigt zum Beispiel die EP 0 822 897 B1 eine solche Vorrichtung. Bei Rakelkammern dieser bekannten Art stellt die stirnseitige Abdichtung ein Problem dar.Doctor blade chambers of this type are used primarily in flexographic printing presses. For example, EP 0 822 897 B1 shows such a device. at Squeegee chambers of this known type set the end seal Problem.

Daher besteht die Aufgabe der vorliegenden Erfindung darin, eine Rakelkammer vorzuschlagen, bei welcher die stirnseitige Abdichtung verbessert ist.Therefore, the object of the present invention is a Propose doctor blade chamber, in which the front seal is improved.

Die Aufgabe wird durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The object is solved by the characterizing part of claim 1.

Bei der erwähnten Verwendung mehrerer Zwischenwände multiplizieren sich ihre Durchlasswahrscheinlichkeiten, so dass in die erste Kammer weniger Farbe eintritt als in die zweite, welche näher an dem gefüllten Farbreservoir der Farbkammer liegt.When using several partition walls mentioned multiply their passage probabilities, so less in the first chamber Color occurs than in the second, which is closer to the filled color reservoir of the Ink chamber lies.

Als vorteilhaft hat sich die Verwendung der zumindest einen Zwischenwand in Verbindung mit verkürzten Rakelmessern erwiesen. Dieser Umstand ist darauf zurückzuführen, dass im Betrieb bei Rakelkammern des Standes der Technik Farbe oder Farbreste an den Rakelmessern entlang kriechen und auf diese Weise direkt an die stirnseitige Dichtung der Rakelkammer gelangen. Eine Verwendung von Rakelmessern, welche bereits zwischen einer Zwischenwand und der Dichtung enden, hilft diesem Problem ab. Die Farbe oder Farbreste tropfen dann vom Ende der Rakelmesser ab und werden in den Kammern gesammelt und durch Bohrungen beziehungsweise Leitungen abgeführt. Diese Maßnahme ist allerdings nur dann Möglich, wenn die Rakelkammer nicht gegen die verkürzte Rakel geneigt wird, da sonst Farbe zwischen dem Ende des verkürzten Rakelmessers und der Dichtung herausläuft.The use of the at least one partition in FIG Proven connection with shortened doctor blades. This is due to it attributed to that in operation with prior art doctor blade chambers Paint or paint residues crawl along the doctor blades and onto them Way directly to the front seal of the doctor chamber. A Use of doctor blades, which are already between a partition and the seal ends up remedying this problem. The paint or paint residue Then drip off the end of the doctor blade and become in the chambers collected and discharged through holes or lines. This However, action is only possible if the doctor chamber is not is inclined against the shortened squeegee, otherwise color between the end of the shortened doctor blade and the seal runs out.

Es ist in diesem Zusammenhang besonders vorteilhaft, die Schließrakel in der beschriebenen Weise auszubilden. Dieser Umstand kommt dadurch zustande, dass die Schließrakel überschüssige, teilweise angetrocknete Farbe von der Rasterwalze abrakelt. Diese Farbreste lagern sich auf der Außenseite des Rakelmessers. Besonders diese Farbreste können die stirnseitigen Dichtungen der Rakelkammer in ihrer Funktion wesentlich beeinflussen, wenn sie in den Raum zwischen der Dichtung und der Walze geraten. Diese Möglichkeit besteht bei der Verwendung verkürzter Schließrakeln nicht, da die Farbreste dann in die ersten oder zweiten Kammern gelangen und von dort aus durch die den jeweiligen Kammern zugeordneten Bohrungen beziehungsweise Leitungen abgeführt werden.In this context, it is particularly advantageous to use the closing squeegee in the training described way. This happens because that the closing squeegee excess, partially dried paint from the Anilox roller scrapes off. These paint residues are stored on the outside of the Doctor blade. These residues of paint in particular can be used on the face seals influence the function of the doctor blade chamber significantly when it is in the Space between the seal and the roller. This possibility does not exist when using shortened closing squeegees, because the ink remains then get into the first or second chambers and from there through the bores or lines assigned to the respective chambers be dissipated.

Erfindungsgemäße Rakelkammern eignen sich sowohl bei der Verwendung eines offenen (Atmosphärendruck) als auch bei der Verwendung eines geschlossenen (Farbe steht unter Druck, wird gegebenenfalls gepumpt) Farbzuführungssystems.Doctor chambers according to the invention are suitable both for use an open (atmospheric pressure) as well as when using a closed (paint is under pressure, may be pumped) Ink delivery system.

Weitere vorteilhafte Ausführungsformen und Ausführungsbeispiele der Erfindung ergeben sich aus den weiteren Ansprüchen, der gegenständlichen Beschreibung und den Zeichnungen.Further advantageous embodiments and exemplary embodiments of the Invention result from the further claims, the objective Description and the drawings.

Figur 1a zeigt einen Schnitt durch ein Ausführungsbeispiel der Erfindung. In dieser Figur ist deutlich zu erkennen, dass die Rasterwalze 2, welche sich im Betrieb in Richtung des gekrümmten Pfeils 3 um die Achse D dreht, der Farbkammerkörper 4 sowie die Schließ- 23 und Arbeitsrakel 24 die Farbkammer 1 begrenzen. Des weiteren ist gezeigt, in welcher Weise die beiden Rakeln von den Halteschienen 16 gehalten werden. Figur 1b zeigt eine Aufsicht auf die Rakelkammer 1 bei abgerückter Rasterwalze 2. Neben den in den anderen Figuren gezeigten Elementen sind die Lagen der Schnitte N-N und M-M zu sowie die Bohrungen 26 für die Befestigungsschrauben der Rakelkammer zu erkennen.Figure 1a shows a section through an embodiment of the invention. In This figure clearly shows that the anilox roller 2, which is in the Operation in the direction of the curved arrow 3 rotates about the axis D, the Ink chamber body 4 and the closing 23 and squeegee 24 die Limit ink chamber 1. It also shows how the two doctor blades are held by the holding rails 16. Figure 1b shows one Supervision of the doctor blade chamber 1 with the anilox roller 2. In addition to the in The elements shown in the other figures are the locations of the cuts N-N and M-M and the holes 26 for the fastening screws of the Recognize doctor chamber.

Die Figuren 2 bis 4 zeigen Ansichten des erwähnten Ausführungsbeipiels, wobei die Rakelmessern und ihre Halteschienen nicht dargestellt sind. werden. Diese Halteschienen werden mit den Befestigungselementen 6 an dem Rakelkammerkörper 4 angebracht. Die stirnseitige Abdeckung der Rakelkammer erfolgt mit Hilfe der Dichtung 7. Diese Dichtung ist in dem Ausführungsbeispiel aus einem flexiblen Material gefertigt. Die Dichtung 7 besitzt ein nicht dargestelltes Klemmblech als stirnseitigen Anschlag. Dieses Klemmblech wird mit ebenfalls nicht dargestellten Schrauben, welche in die Gewindebohrungen 17 greifen, am Rakelkammerkörper 4 arretiert. In diesem Zusammenhang wird die Dichtung 7 in der Regel zwischen dem Steg des Rakelkammerkörpers 25 und dem Klemmblech arretiert. Zwischen der Dichtung und der Einfärbezone 14 der Rasterwalze befinden sich die beiden Zwischenwände 11 und 13, welche die ersten und zweiten Kammern 9 und 10 definieren.FIGS. 2 to 4 show views of the exemplary embodiment mentioned, the doctor blades and their holding rails are not shown. become. These holding rails are fastened to the fastening elements 6 on the Doctor chamber body 4 attached. The front cover of the Doctor chamber is done with the help of seal 7. This seal is in the Embodiment made of a flexible material. The seal 7 has a clamping plate, not shown, as an end stop. This Clamping plate is also with screws, not shown, which in the Grip threaded holes 17, locked on the doctor blade chamber 4. In this Context, the seal 7 is usually between the web of the Squeegee chamber body 25 and the clamping plate locked. Between the Seal and the inking zone 14 of the anilox roller are the two Partitions 11 and 13, which the first and second chambers 9 and 10th define.

Aus dieser Beschreibung wird klar, dass unter Einfärbezone 14 diejenigen Abschnitte der Rasterwalze 2 zu verstehen sind, die willentlich eingefärbt werden. In den dargestellten Vorrichtungen ist das in den in axialer Richtung zentralen Bereichen der Rasterwalze 2 der Fall, welche zwischen den beiden zweiten Zwischenwänden 13 befindlich sind. Die durchaus mögliche Einfärbung der Rasterwalze im Bereich der Kammern 9, 10 und der Dichtung 7 in den Randbereichen der Farbwalze erfolgt ungewollt.From this description it is clear that 14 ink zones are those Sections of the anilox roller 2 are to be understood, which are colored at will become. In the devices shown this is in the axial direction central areas of the anilox roller 2, which is between the two second partitions 13 are located. The most possible Coloring of the anilox roller in the area of the chambers 9, 10 and the seal 7 unwanted in the edge areas of the ink roller.

Aus fertigungstechnischen Gründen sind die beiden Zwischenwände 11, 13 in den gezeigten Beispielen Teil eines einstückigen Zwischenwandkörpers 22, welcher mit einer nicht dargestellten Befestigungsschraube am Rakelkammerkörper 4 befestigt ist. Diese Schraube wird ihrerseits in die Gewindebohrung 21 geschraubt. Farbe oder Farbreste, welche in die beiden Kammer gelangen, werden durch die Bohrungen 18 und 19 abgeführt, welche die Funktion eines Abflusses haben. Eine solche Bohrung kann natürlich auch so ausgestaltet sein, dass sie für mehrere Kammern zugleich eine Abflussfunktion wahrnimmt. Das ist zum Beispiel dann der Fall, wenn eine Zwischenwand 11 zentral über einer Bohrung verläuft und die Bohrung einen Durchmesser hat welcher größer ist als die Zwischenwandstärke.For manufacturing reasons, the two partitions 11, 13 are in the examples shown part of a one-piece partition wall body 22, which with a fastening screw, not shown, on Doctor chamber body 4 is attached. This screw is in turn in the Threaded hole 21 screwed. Paint or paint residues, which in the two Arrive chamber, are discharged through the holes 18 and 19, which have the function of a drain. Such a hole can of course also be designed so that they have one for several chambers at the same time Discharge function. This is the case, for example, if one Partition 11 runs centrally over a hole and the hole one The diameter is larger than the partition wall thickness.

Die Figuren 5 bis 7 zeigen wiederum das Ausführungsbeispiel einschließlich der Rakelmesser und Halteschienen. Die Schließrakel 23 endet wie erwähnt bereits in der ersten Kammer 9. Daher sollte die gezeigte Rakelkammer 1 nicht gegen das Schließrakel geneigt werden.Figures 5 to 7 again show the embodiment including the doctor knife and holding rails. The closing squeegee 23 ends as mentioned already in the first chamber 9. Therefore, the doctor chamber 1 shown should not be inclined against the closing squeegee.

Der mehrfach erwähnte Unterschied zu den bereits beschrieben Figuren 2 bis 4 besteht in der hier vorgenommenen Darstellung der Halteschienen für die Rakelmesser 16. Figur 7 zeigt überdies wesentliche Merkmale der Erfindung im Schnitt. So sind hier die Abflussbohrungen 18, 19, der einstückige Zwischenwandkörper 22 und die Dichtung 7 deutlich zu sehen. Des weiteren wird gezeigt, in welcher Weise die Dichtung 7 zwischen dem Steg 26 des Rakelkammerkörpers 4 und dem nicht dargestellten Klemmblech, welches bei der Beschreibung des ersten Ausführungsbeipiels bereits erwähnt wurde, befestigt ist.The difference mentioned several times to the already described Figures 2 to 4 consists in the representation made here of the holding rails for the Doctor knife 16. Figure 7 also shows essential features of the invention in Cut. So here are the drain holes 18, 19, the one-piece Intermediate wall body 22 and the seal 7 can be seen clearly. Furthermore shows how the seal 7 between the web 26 of the Doctor blade chamber body 4 and the clamping plate, not shown, which at the description of the first exemplary embodiment has already been mentioned, is attached.

Bei beiden gezeigten Ausführungsbeispielen wurde lediglich eine zweite Zwischenwand eingefügt. Es ist jedoch auch möglich und erfindungsgemäß weitere Zwischenwände einzuführen.In the two exemplary embodiments shown, only a second one was used Partition inserted. However, it is also possible and according to the invention to introduce further partitions.

Zu erwähnen ist auch, dass bei beiden Ausführungsbeispielen Farbzuläufe im zentralen Bereich der Farbkammer 1 vorhanden sind, welche in den Figuren nicht gezeigt wurden.
