Description

Die Erfindung betrifft Farbteiler für ein Flexodruckmaschinen-Farbwerk zwischen zwei verschiedene Farben fördernden Bereichen einer Farbwalze, an die zwei Rakelmesser oberhalb und unterhalb von Farbstauräumen angestellt sind, die durch Farbabteilplatten voneinander getrennt sind.The invention relates to ink dividers for a flexographic printing press inking unit between two different ink-promoting areas of an inking roller, to which two doctor blades are placed above and below ink storage spaces, which are separated from one another by ink compartment plates.

Eine derartige Vorrichtung ist beispielsweise aus der DE-OS 33 20 638 bekannt. Bei diesen Vorrichtungen liegen die Stirnflächen der Farbabteilbleche durch Federkraft zwecks Abdichtung direkt an dem Mantel der Farbwerkswalze an. Die seitliche Abdichtung des Farbstauraumes erfolgt durch die Anlage der Farbabteilbleche an die Stirnflächen der Rakelmesser bzw. der Abstreifmesser. Derartige Vorrichtungen weisen den Nachteil auf, daß zum einen eine ausreichende Abdichtung des Farbstauraumes unter allen Betriebsbedingungen, besonders bei dünnflüssigen Druckfarben, nur schwer möglich sein dürfte und daß zum anderen keine durchgehenden Rakelmesser verwendet werden können, denn diese müssen entsprechend der Anzahl und der Länge der benötigten Farbstauräume dimensioniert sein. Des weiteren besteht die Gefahr, daß die Manteloberfläche durch das Farbabteilblech beschädigt wird. Bei dieser Ausführung verbleibt ein Farbring an der Farbwalze, der bei höheren Drehzahlen zum Abspritzen neigt oder bei längerer Betriebsdauer antrocknet.Such a device is known for example from DE-OS 33 20 638. In the case of these devices, the end faces of the ink compartment plates rest against the jacket of the inking unit roller by spring force for the purpose of sealing. The ink storage space is sealed at the side by the ink compartment sheets bearing against the end faces of the doctor blades or the doctor blades. Such devices have the disadvantage that, on the one hand, adequate sealing of the ink storage space under all operating conditions, especially in the case of low-viscosity printing inks, should only be possible with difficulty and that, on the other hand, no continuous doctor blades can be used, because these must correspond to the number and length of the required color storage spaces must be dimensioned. Furthermore, there is a risk that the surface of the jacket will be damaged by the paint compartment plate. In this version, a color ring remains on the ink roller, which tends to spray off at higher speeds or dries over a longer period of operation.

Aufgabe der Erfindung ist es, eine Farbteilervorrichtung der eingangs definierten Gattung aufzuzeigen, mit der sowohl eine sichere Abdichtung des Farbstauraumes unter allen Betriebsbedingungen und bei einfacher Fertigung der benötigten Teile gewährleistet ist, als auch eine beliebige Aufteilung der Farbstauräume erfolgen kann, die Farbringbildung vermieden wird und daß auch durchgehende Rakelmesser bzw. Abstreifmesser verwendet werden können. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen schematisch:

  • Fig.1 eine Seitenansicht eines erfindungsgemäßen Farbteilers,
  • Fig.2 einen Schnitt entlang der Linie II-II der Darstellung gemäß Fig.1 und
  • Fig.3 eine Draufsicht des Farbteilers gemäß Fig.1 und
  • Fig.4 einen Einschub mit zwei Farbteilerelementen.
The object of the invention is to provide a color divider device of the type defined at the outset, with which both a reliable sealing of the ink storage space is guaranteed under all operating conditions and with simple manufacture of the required parts, and an arbitrary division of the ink storage spaces can take place, the formation of color rings is avoided and that continuous doctor blades or doctor blades can be used. This task is accomplished through the application of the features of the characterizing part of claim 1 solved. Further developments result from the subclaims and from the description in connection with the drawings. These show schematically:
  • 1 shows a side view of a color divider according to the invention,
  • 2 shows a section along the line II-II of the illustration according to FIG. 1 and
  • 3 shows a top view of the color divider according to FIG. 1 and
  • 4 shows an insert with two color divider elements.

Wie aus den Figuren 1 bis 3 hervorgeht, ist an eine Farbwerkswalze (1), beispielsweise eine Aniloxwalze, ein Rakelmesser (2) angestellt, durch das die aus einem Farbstauraum mit einer Farbe aufgebrachte Farbe abgerakelt wird. Um die Farbwerkswalze (1) in beiden Richtungen betreiben zu können, ist vorzugsweise auf der anderen Seite des Farbstauraumes S ein weiteres Rakelmesser (3) angestellt, durch das bei der anderen Drehrichtung die Farbe abgerakelt wird. Falls lediglich ein Betrieb in der einen Richtung erforderlich ist, kann anstelle des zweiten Rakelmessers (3) auch ein Abstreifmesser verwendet werden. Bei der Ausführungsform gemäß Fig.1 kann die Farbwerkswalze (1) entsprechend dem Doppelpfeil (4) in Uhrzeigerrichtung und Gegenuhrzeigerrichtung rotieren.As can be seen from FIGS. 1 to 3, a doctor blade (2) is attached to an inking unit roller (1), for example an anilox roller, by means of which the ink applied from a ink storage space with one ink is doctored off. In order to be able to operate the inking roller (1) in both directions, another doctor blade (3) is preferably placed on the other side of the ink storage space S, by means of which the ink is doctored in the other direction of rotation. If only operation in one direction is required, a doctor blade can also be used instead of the second doctor blade (3). In the embodiment according to FIG. 1, the inking roller (1) can rotate clockwise and counterclockwise in accordance with the double arrow (4).

Um die Farbwerkswalze (1) in Achsrichtung gesehen mit unterschiedlichen Farben einfärben zu können, werden, wie aus Fig.4 ersichtlich, voneinander getrennte Farbmulden (5, 6) benötigt. Da häufig Druckträger auch mit unterschiedlichen Farben bedruckt werden, müssen die Farbmulden hinsichtlich ihrer axialen Ausdehnung entsprechend verändert werden. Bei der erfindungsgemäßen Farbteilervorrichtung ist dies ohne die Verwendung von Einkerbungen bzw. Vertiefungen am Umfang der Farbwerkswalze kontinuierlich möglich, wobei auch durchgehende, d.h. nicht unterteilte Rakelmesser (2, 3), verwendet werden können.In order to be able to dye the inking roller (1) in the axial direction with different colors, separate ink wells (5, 6) are required, as can be seen in FIG. Since printing media are often also printed with different colors, the ink wells must be changed accordingly in terms of their axial extent. In the ink splitter device according to the invention, this is possible continuously without the use of notches or depressions on the circumference of the inking roller, it also being possible to use continuous, ie non-subdivided doctor blades (2, 3).

Erfindungsgemäß wird deshalb die einem Farbstauraum zugewandte Seite einer Farbabteiltrennplatte (9) mit einer Dichtung (7) belegt. Die an der Farbwerkswalze (1) anliegende Dichtung (7) wird über den zugehörigen Mantelabschnitt M mit einem Gleitbelag (8) versehen. Die Farbabteilplatte (9) kann beispielsweise aus einer nichtrostenden Stahlplatte bestehen. Als Material für die Dichtung (7) kommt z.B. Gummi oder Neoprene in Frage. Als Gleitbelag (8) eignet sich z.B. Teflon.According to the invention, the side of an ink compartment separating plate (9) facing an ink storage space is therefore covered with a seal (7). The seal (7) resting on the inking roller (1) is provided with a sliding coating (8) via the associated jacket section M. The color compartment plate (9) can for example consist of a stainless steel plate. The material for the seal (7) is e.g. Rubber or neoprene in question. A suitable sliding surface (8) is e.g. Teflon.

In erfindungsgemäßer Weise ist die Dichtung (7) an der Farbabteilplatte (9) in ihrer Form so festgelegt, daß sie übersteht und zwar so, daß sie mit den überstehenden Bereichen jeweils unterhalb der Rakelmesser (2) und (3) elastisch anliegt, d.h., die Dichtung (7) jeweils in Drehrichtung der Farbwalze (1) gesehen, vor der Rakel (2) bzw. (3) zum Anliegen kommt. Dadurch ergibt sich der Voteil, daß trotz einer unvermeidlichen Durchbiegung der Rakeln (2) bzw. (3) eine exakte Abdichtung erhalten bleibt. Der überstehende, an dem Mantelabschnitt M der Farbwerkswalze liegende Teil, der in seiner Krümmung an die Farbwerkswalze (1) angepaßt ist, ist zwecks Schonung der Farbwerkswalze (1) mit dem Gleitmaterial (8) beschichtet.In the manner according to the invention, the shape of the seal (7) on the ink compartment plate (9) is such that it protrudes and in such a way that it rests elastically with the protruding areas below the doctor blades (2) and (3), ie the seal (7) seen in the direction of rotation of the inking roller (1), before the doctor blade (2) or (3) comes to rest. This results in the advantage that, despite an inevitable deflection of the doctor blades (2) or (3), an exact seal is retained. The protruding part lying on the jacket section M of the inking roller, the curvature of which is adapted to the inking roller (1), is coated with the sliding material (8) in order to protect the inking roller (1).

Durch die erfindungsgemäße Farbabteilplatte (9) mit der Dichtung (7) ergibt sich somit eine zuverlässig abdichtende seitliche Begrenzung eines Farbstauraumes S. Falls trotzdem seitlich etwas Farbe austritt, so wird in vorteilhafter Weise durch auf der anderen Seite der Farbabteilplatte (9) vorgesehene Abflußkanäle bildende Ausnehmungen (10, 11) dafür gesorgt, daß die austretende Farbe nicht antrocknet oder abgeschleudert wird, sondern über diese Ausnehmungen (10, 11) entlang der Farbabteilplatte (9) abgeführt und einer nicht gezeigten Farbauffangvorrichtung zugeleitet wird. Es ist vorteilhaft, die einzelnen Ausnehmungen (10, 11) durch Stege (12, 13) zu unterteilen.The ink compartment plate (9) according to the invention with the seal (7) thus results in a reliably sealing lateral boundary of an ink storage space S. If, nevertheless, some paint escapes laterally, drainage channels provided on the other side of the ink compartment plate (9) are advantageously formed Recesses (10, 11) ensure that the emerging paint is not dried or thrown off, but is removed via these recesses (10, 11) along the ink compartment plate (9) and fed to an ink collecting device, not shown. It is advantageous to subdivide the individual recesses (10, 11) by means of webs (12, 13).

Fig.4 zeigt einen Einschub (19) mit zwei Dichtungen (15, 16), die entsprechend der bereits beschriebenen Dichtung (7) dimensionert und an Farbabteilplatten (21, 22) befestigt, beispielsweise angeklebt sind. Mit dem Einschub (19) kann somit an beliebiger Stelle einer Farbwalze (14) eine Unterteilung, d.h. eine axiale Begrenzung erfolgen. Der Einschub (19) trennt zwei vorzugsweise unterschiedliche Farben aufweisende Mulden (5, 6). Auch bei der Ausführungsform gemäß Fig.4 sind die Dichtungen (15, 16) mit jeweils einem Gleitbelag (17 bzw. 18) versehen und die Farbabteilplatten (21, 22) weisen Ausnehmungen (23, 24) auf, die ggf. ebenfalls durch Stege getrennt bzw. unterteilt werden können.4 shows an insert (19) with two seals (15, 16) which are dimensioned in accordance with the seal (7) already described and attached to color compartment plates (21, 22), for example glued on. A subdivision, ie an axial limitation, can thus take place at any point on an inking roller (14) with the insert (19). The insert (19) separates two troughs (5, 6) which preferably have different colors. In the embodiment according to FIG. 4, the seals (15, 16) are each provided with a sliding coating (17 or 18) and the color compartment plates (21, 22) have recesses (23, 24), which may also be provided by webs can be separated or divided.

Falls seitlich der Farbmulden (5) oder (6) in die mit einer Leiste (20) versehene Trennfuge bzw. in diesen Zwischenraum Farbe austritt, so wird diese jeweils über die Ausnmehmungen (23, 24) abgeleitet und in einen nicht gezeigten Auffangbehälter geführt. Der Einschub (19) kann also entlang der Farbwalze (14) an beliebiger Stelle angesetzt werden, so daß die Ausdehnung und Aufteilung der Farbmulden (5) und (6) in beliebiger Weise erfolgen können. Zur Vermeidung der Farbringbildung auf der Farbwalze (1) bzw. (14) ist es wesentlich, daß das Rakelmesser (2) bzw. (3) seitlich der Farbabteilplatte (9) bzw. (21, 22) übersteht.If paint escapes to the side of the paint troughs (5) or (6) into the separating joint provided with a strip (20) or into this space, this is in each case drained off via the recesses (23, 24) and guided into a collecting container (not shown). The insert (19) can thus be placed anywhere along the inking roller (14), so that the expansion and division of the ink wells (5) and (6) can take place in any manner. In order to avoid the formation of a color ring on the inking roller (1) or (14), it is essential that the doctor blade (2) or (3) laterally protrude from the ink compartment plate (9) or (21, 22).
