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 doctoring chamber for rotary printing machines according to 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 Rakelkammem dieser bekannten Art stellt die stirnseltige Abdichtung ein Problem dar.Such doctor chambers are used primarily in flexographic printing machines. For example, EP 0 822 897 B1 shows such a device. In Rakelkammem this known type, the frontal sealing presents a problem.

Um den im Bereich der stirnseitigen Abdichtungen auftretenden Staudruck, durch welchen die Farbe nach außen gedrückt wird, zu verringert, schlägt die DE 43 02 671 A1 eine an der Walze anliegende, stirnseitige Abdichtung vor, die aus einzelnen, sich in Umfangsrichtung dieser Walze erstreckenden Stegen besteht. Auch die DE 94 05 883 U1 zeigt eine solche Anordnung mehrerer Stege.In order to reduce the dynamic pressure occurring in the region of the end seals, by which the color is pressed to the outside, proposes DE 43 02 671 A1 an applied to the roller, frontal seal before, consisting of individual, extending in the circumferential direction of this roller webs consists. Also DE 94 05 883 U1 shows such an arrangement of a plurality of webs.

In der DE 42 41 792 A1 wird eine stimseitige Abdichtung vorgeschlagen, die einen Dichtungsschuh umfasst, welcher mit mehreren Dichtungsrippen nach Art einer Labyrinthdichtung ausgebildet ist. In einer Ausführungsform verlaufen die Dichtungsrippen parallel zur Umfangsrichtung der Walze, die mit der stirnseitigen Abdichtung in Wirkverbindung steht.In DE 42 41 792 A1 an end seal is proposed which comprises a sealing shoe which is formed with a plurality of sealing ribs in the manner of a labyrinth seal. In one embodiment, the sealing ribs extend parallel to the circumferential direction of the roller, which is in operative connection with the front-side seal.

Bei der erwähnten Verwendung mehrerer Farbkammern bildende Rippen oder Stege multiplizieren sich die 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 said plurality of color chambers forming ribs or webs multiply the transmission probabilities, so that in the first chamber less ink enters than in the second, which is closer to the filled ink reservoir of the ink chamber.

Jedoch auch die erwähnten Verbesserungen der stirnseitigen Dichtigkeit durch die Verwendung mehrerer Stege oder Rippen lässt noch Wünsche offen.However, the aforementioned improvements of the frontal tightness by the use of multiple webs or ribs leaves nothing to be desired.

Daher besteht die Aufgabe der vorliegenden Erfindung darin, eine Rakelkammer vorzuschlagen, bei welcher die stimseitige Abdichtung verbessert ist.Therefore, the object of the present invention is to propose a doctor chamber in which the end 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.

Demnach wird die Verwendung von zumindest einer Zwischenwand in Verbindung mit verkürzten Rakelmessem vorgeschlagen. Die dadurch verbesserte Dichtwirkung ist darauf zurückzuführen, dass im Betrieb bei Rakelkammern des Standes der Technik Farbe oder Farbreste an den Rakelmessem entlang kriechen und auf diese Weise direkt an die stimseitige 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.
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.Accordingly, the use of at least one intermediate wall in connection with shortened doctor blades is proposed. The thus improved sealing effect is due to the fact that in operation in doctoring chambers of the prior art, color or ink residues creep along the doctor blade and in this way reach the end-face seal of the doctor blade chamber directly. A use of doctor blades, which already end between a partition and the seal, helps this problem. The paint or paint residues then drip from the end of the doctor blade and are collected in the chambers and discharged through holes or pipes. However, this measure is only possible if the doctor chamber is not tilted against the shortened doctor blade, since otherwise runs out of ink between the end of the shortened doctor blade and the seal.
It is particularly advantageous in this context to form the closing squeegee in the manner described. This circumstance comes about because the closing squeegee scrapes off excess, partially dried ink from the anilox roller. These paint residues are deposited on the outside of the doctor blade. In particular, these ink residues can significantly affect the function of the face seals of the doctor blade chamber when they fall into the space between the seal and the roller. This possibility does not exist when using shortened closing doctor blades, since the ink residues then pass into the first or second chambers and are discharged from there through the bores or lines assigned to the respective chambers.

Erfindungsgemäße Rakelkammem 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 blade combs according to the invention are suitable both when using an open (atmospheric pressure) and when using a closed (color is under pressure, optionally pumped) Farbzuführungssystems.

Weitere vorteilhafte Ausführungsformen und Ausführungsbeispiele der Erfindung ergeben sich aus den weiteren Ansprüchen, der gegenständlichen Beschreibung und den Zeichnungen.Further advantageous embodiments and embodiments of the invention will become apparent from the other claims, the physical 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.
Die Figuren 2 bis 4 zeigen Ansichten des erwähnten Ausführungsbeispiels, wobei die Rakelmesser und ihre Halteschienen nicht dargestellt sind. 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.
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.
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 Kammern 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.
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.
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 Ausführungsbeispiels bereits erwähnt wurde, befestigt ist.
Bei beiden gezeigten Ausführungsbeispielen wurde lediglich eine zweite Zwischenwand eingefügt. Es ist jedoch auch möglich und erfindungsgemäß weitere Zwischenwände einzuführen.
Zu erwähnen ist auch, dass bei beiden Ausführungsbeispielen Farbzuläufe im zentralen Bereich der Farbkammer 1 vorhanden sind, welche in den Figuren nicht gezeigt wurden.

In this figure, it can be seen clearly that the anilox roller 2, which rotates in operation in the direction of the curved arrow 3 about the axis D, the Ink chamber body 4 and the closing 23 and work doctor blade 24 limit the ink chamber 1. Furthermore, it is shown how the two doctor blades are held by the support rails 16. FIG. 1b shows a plan view of the doctoring chamber 1 with the anilox roller 2 removed. In addition to the elements shown in the other figures, the positions of the cuts NN and MM are to be recognized, as well as the bores 26 for the fastening screws of the doctoring chamber.
Figures 2 to 4 are views of the aforementioned embodiment, wherein the doctor blade and its support rails are not shown. These retaining rails are attached to the doctoring chamber body 4 with the fastening elements 6. The frontal cover of the doctoring chamber is effected by means of the seal 7. This seal is made in the embodiment of a flexible material. The seal 7 has a clamping plate, not shown, as an end stop. This clamping plate is locked with likewise not shown screws which engage in the threaded holes 17 on the doctoring chamber body 4. In this connection, the seal 7 is usually locked between the web of the doctor chamber body 25 and the clamping plate. Between the seal and the inking zone 14 of the anilox roller are the two intermediate walls 11 and 13 which define the first and second chambers 9 and 10.
From this description, it will be understood that by coloration zone 14 are meant those portions of the anilox roller 2 which are intentionally colored. In the illustrated devices, this is the case in the axially central regions of the anilox roller 2, which are located between the two second partitions 13. The possible possible coloring of the anilox roller in the region of the chambers 9, 10 and the seal 7 in the edge regions of the inking roller occurs unintentionally.
For manufacturing reasons, the two partitions 11, 13 in the examples shown part of a one-piece intermediate wall body 22 which is secured by a fastening screw, not shown, on the doctor chamber body 4. This screw is in turn screwed into the threaded hole 21. Paint or paint residues, which get into the two chambers are discharged through the bores 18 and 19, which have the function of an outflow. Of course, such a bore can also be designed so that it simultaneously performs a drainage function for several chambers. This is the case, for example, when an intermediate wall 11 extends centrally over a bore and the bore has a diameter which is greater than the intermediate wall thickness.
Figures 5 to 7 again show the embodiment including the doctor blades and support rails. The closing squeegee 23 ends, as already mentioned, in the first chamber 9. Therefore, the squeegee chamber 1 shown should not be inclined against the closing squeegee.
The difference mentioned several times to those already described in FIGS. 2 to 4 consists in the representation of the support rails for the doctor blades 16 described here. FIG. 7 moreover shows essential features of the invention in section. So here are the drain holes 18, 19, the one-piece partition body 22 and the seal 7 clearly visible. Furthermore, it is shown how the seal 7 between the web 26 of the doctor chamber body 4 and the clamping plate, not shown, which was already mentioned in the description of the first embodiment, is attached.
In both embodiments shown only a second partition was inserted. However, it is also possible and inventively introduce more partitions.
It should also be mentioned that in both embodiments ink feeds are present in the central area of the ink chamber 1, which were not shown in the figures.
