Description

Die Erfindung betrifft eine Farbkastentrennung gemäß dem Oberbegriff von Anspruch 1.The invention relates to a color box separation according to the preamble of claim 1.

Bei Bogenoffsetdruckmaschinen wird die zu verdruckende Farbe von einem Farbkasten auf eine Farbkastenwalze und von dieser auf nachgeordnete Farbwerkwalzen übertragen. Mit der Farbkastenwalze wirken ein Farbmesser bzw. Dosierelemente zusammen, so dass die Druckfarbe entsprechend dem Farbbedarf des Sujets zonal unterschiedlich zugeführt werden kann.In sheet-fed offset printing machines, the ink to be printed is transferred from an ink fountain to an ink fountain roller and from there to downstream ink fountain rollers. With the ink fountain roller a color meter or metering act together, so that the ink can be supplied zonal different according to the color requirements of the subject.

Sollen in einem Farbkasten mehrere Druckfarben nebeneinander verdruckt werden bzw. soll der Farbkasten nicht über die gesamte Formatbreite der Druckmaschine mit Farbe gefüllt werden, so werden Farbkastentrenner verwendet, welche das Volumen des Farbkastens unterteilen.If a plurality of printing inks are to be printed side by side in one ink fountain or if the ink fountain is not to be filled with ink over the entire format width of the printing press, color box separators are used which subdivide the volume of the ink fountain.

Die EP 0 374 092 B1 zeigt einen Farbkastentrenner, welcher aus zwei parallel zueinander angeordneten Metallplatten besteht, zwischen die ein Dichtelement aus Kunststoff gelegt und welches über Schraubelemente sowohl gegen den Farbkastenboden als auch gegen die Farbkastenwalze gedrückt wird. Diese bekannte Vorrichtung baut relativ aufwendig, ferner wird durch die Schraubelemente ein hoher Druck gegenüber der Farbkastenwalze und dem Boden des Farbkastens ausgeübt. Bei Verwendung von mehreren Farbkastentrennern innerhalb eines Farbkastens ist es so möglich, dass die Farbkastenwalze zu stark abgebremst wird, was eine entsprechende Belastung des Antriebes der Farbkastenwalze bedingt. Ferner ist auch nicht auszuschließen, dass durch die hohen Anstellkräfte der Farbkasten und/oder die Farbkastenwalze durchgebogen werden, so dass es zu keiner exakten Farbdosierung mehr kommt.The EP 0 374 092 B1 shows a Farbkastentrenner, which consists of two mutually parallel metal plates between which a sealing element made of plastic and which is pressed via screw both against the ink fountain bottom and against the ink fountain roller. This known device is relatively expensive, also exerted by the screw a high pressure against the ink fountain roller and the bottom of the ink fountain. When using multiple color box separators within a color box, it is possible that the ink fountain roller is braked too much, which causes a corresponding load on the drive of the ink fountain roller. Furthermore, it can not be ruled out that the ink fountain and / or the ink fountain roller are deflected by the high contact forces, so that there is no longer any exact color dosage.

Ein bezüglich der Farbkastenwalze an- und abstellbar gelagerter Farbkasten mit an dessen Unterseite angebrachten, linear beweglichen Farbdosierelementen ist aus der DE 195 04 583 C1 bekannt.An adjustable with respect to the ink fountain roller and adjustable color box mounted on the underside, linearly movable Farbdosierelementen is from the DE 195 04 583 C1 known.

Gemäß der DE 203 12 668 U1 ist vorgesehen, dass die Farbkastentrennung als eine in den Farbkasten einsetzbare, passgenaue zu einem Teilumfang der Farbkastenwalze sowie des Farbkastenbodens geformte Platte ausgebildet ist, welche an ihrem hinteren Ende einen Teil des Farbkastens hintergreift. An den zum Farbkastenboden sowie den Farbdosierelementen zugewandeten Bereichen weist die Platte ein flexibles Dichtelement in Form eines aufgeklebten Gummistreifens auf. Dieser ist vorzugsweise selbstklebend ausgebildet und kann nach Gebrauch bzw. bei Verschleiß in einfacher Weise entfernt und durch einen neuen Streifen ersetzt werden. Die Vorrichtung ist aber schwierig zu handhaben.According to the DE 203 12 668 U1 It is provided that the color box separation is formed as an insertable into the ink fountain, accurately formed to a partial extent of the ink fountain roller and the ink fountain bottom plate, which engages behind a part of the ink fountain at its rear end. At the areas facing the ink fountain floor and the ink metering areas, the plate has a flexible sealing element in the form of a glued rubber strip. This is preferably self-adhesive and can be easily removed after use or wear and replaced by a new strip. The device is difficult to handle.

Die DE 202006011283 U1 zeigt eine Farbkastentrennung bestehend aus einer Platte, die an ihrem hinteren Ende einen Teil des Farbkastens mittels eines Rastelementes hintergreift.The DE 202006011283 U1 shows a color box separation consisting of a plate which engages behind a part of the ink fountain by means of a locking element at its rear end.

Aufgabe der Erfindung ist es, eine Farbkastentrennung gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so dass eine dichte Trennung bei konstruktiv möglichst einfacher Ausführung und einfachster Handhabung erhalten wird.The object of the invention is to expand such a color box separation according to the preamble of claim 1, so that a dense separation with structurally simplest possible design and ease of use is obtained.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further developments of the invention will become apparent from the dependent claims.

In einem Farbkasten (Farbreservoir) einer Druckmaschine wird üblicherweise jeweils nur eine Farbe je Druckwerk geführt. Durch das werkzeuglose Einsetzen (einklinken) entsprechend geformter Trennstege kann der Farbraum in beliebig viele, gegeneinander abgedichtete Einzelräume unterteilt werden, die das Führen mehrerer Farben ermöglichen. Hierbei befindet sich in den einzelnen Trennstegen an ihrer, dem Duktor abgewandten Seite ein in den Steg eingelassenes, federndes Druckstück, welches sowohl die Arretierung des in den angeschwenkten Farbkasten eingesetzten Steges, als auch den für die Dichtflächen erforderlichen Anpressdruck sicherstellt. Die Abstützung erfolgt über eine rückwärtig am Farbkasten angebrachte, entsprechend ausgeführte Leiste.In a color box (ink reservoir) of a printing machine usually only one color per printing unit is performed. Due to the tool-free insertion (latching) correspondingly shaped dividers, the color space can be divided into any number of mutually sealed individual spaces that allow the guiding of multiple colors. Here is located in the individual dividers on their side facing away from the ductor a recessed in the web, resilient pressure piece, which ensures both the locking of the web inserted in the swiveled ink fountain, as well as the contact pressure required for the sealing surfaces. The support is via a rear mounted on the color box, appropriately executed bar.

Eine spezielle Ausgestaltung der am drehenden Farbduktor anliegenden Dichtfläche ermöglicht es, dass die Verreiberwalzen des Farbwerkes mit der für die Erzeugung einer streifenfreien Druckbilderzeugung erforderlichen Mindestverreibung betrieben werden können, ohne dass die dadurch entstehende Vermischung der unterschiedlichen Farben, die bei dieser als Iris-Druck bekannten, besonderen Drucktechnik auf dem Druckprodukt gewünscht ist, als Störung für den Farbkasten zurück übertragen wird und dort die einzelnen Reservoirs verunreinigt.A special embodiment of the sealing surface resting on the rotating ink duct makes it possible for the inking rollers of the inking unit to be operated with the minimum trituration required for producing a streak-free printing image without the resulting mixing of the different colors known as iris printing, special printing technique on the printed product is desired, is transmitted back as a disturbance for the ink fountain and there contaminated the individual reservoirs.

Dies geschieht dergestalt, dass die in Drehrichtung des Duktors gesehen auf den Trennsteg zulaufende und durch den Kontakt mit dem verreibenden Farbwerk mit vermischten Farbbereichen verunreinigte Mantelfläche des Duktors von der sich gegen die Laufrichtung verjüngenden Dichtfläche eines Trennsteges geteilt wird, und die auf dem Mantel befindliche Farbe die sich zur Dosierstelle hin verbreiternde Dichtfläche in ihr Ausgangsreservoir zurückgefördert wird. Hierdurch wird eine gegenseitige Verunreinigung benachbarter Farbreservoirs minimiert.This is done in such a way that seen in the direction of rotation of the ductor tapered onto the divider and contaminated by the contact with the rubbing inking unit with mixed color areas jacket surface of the ductor is divided by the tapered against the direction sealing surface of a divider, and located on the jacket color the sealing surface widening towards the dosing point is fed back into its outlet reservoir. This minimizes mutual contamination of adjacent paint reservoirs.

Die Figuren 1 und 2 zeigen eine Farbkastenwalze 1, welche in Uhrzeigerrichtung angetrieben wird. Bezüglich der Farbkastenwalze 1 ist ein Farbkasten 2 an- und abstellbar gelagert.The Figures 1 and 2 show an ink fountain roller 1, which is driven in the clockwise direction. With respect to the ink fountain roller 1, a color box 2 is mounted on and off adjustable.

An der Unterseite des Farbkastens 2 sind linear beweglich Farbdosierelemente 3 eingelassen, die bei an die Farbkastenwalze 1 angestelltem Farbkasten 2 Druckfarbe in vorgesehenen Farbschichtdicken auf der Farbkastenwalze 1 dosieren.On the underside of the ink fountain 2 linearly metered color metering elements 3 are inserted, which meter when inked to the ink fountain roller 1 ink fountain 2 ink in the intended ink layer thicknesses on the ink fountain roller 1.

Entsprechend der Kontur eines Abschnittes der Farbkastenwalze 1, des Bodens des Farbkastens 2 sowie des Bereiches zwischen Boden und den Farbdosierelementen 3 ist eine Platte 4 geformt, welche bei angestelltem Farbkasten 2 (Figur 1) in den Farbkasten 2 eingelegt und durch Federkraft an die Farbkastenwalze 1 sowie den Boden des Farbkastens 2 gedrückt wird. Im hinteren Ende des Farbkastens 2 ist dazu eine Leiste 6 über die Formatbreite des Farbkastens 2 sich erstreckend angebracht, gegen die die Platte 4 der erfindungsgemäßen Farbwerktrennung eingesetzt wird. Hierzu ist in der von der Farbkastenwalze 1 abgewandten Rückseite der Platte 4 eine mittels einer Feder 7 belastete Klinke 5 (hier als Kugel ausgeführt) vorgesehen. Durch die federnde Klinke 5 wird so die Platte 4 ohne Anstellen des Farbkastens 2 an die Farbkastenwalze 1 mit einem angemessenen Anstelldruck sowohl gegenüber dem Farbkasten 2 als auch der Farbkastenwalze 1 angestellt. Zum leichten Einsetzen weist die Leiste 6 an ihrer Oberseite eine nach unten weisende Einführschräge auf, über die die Klinke 5 leicht eingerastet werden kann. Die Unterseite der Leiste 6 ist als leicht nach oben angeschrägte Rastfläche ausgebildet. Die zwischen Einführschräge und Rastfläche liegende Kante gewährleistet den sicheren Halt der Platte 4 mittels der Klinke 5. Die Abdichtung der Farbkastenteilbereiche ist so sichergestellt.According to the contour of a portion of the ink fountain roller 1, the bottom of the ink fountain 2 and the area between the bottom and the Farbdosierelementen 3, a plate 4 is formed, which when the ink fountain 2 (FIG. FIG. 1 ) is inserted into the ink fountain 2 and pressed by spring force to the ink fountain roller 1 and the bottom of the ink fountain 2. In the rear end of the ink fountain 2 to a bar 6 is mounted extending over the format width of the ink fountain 2, against which the plate 4 of the inking unit according to the invention is used. For this purpose, in the side facing away from the ink fountain roller 1 back of the plate 4 is a loaded by a spring 7 pawl 5 (designed here as a ball) is provided. By the resilient latch 5 so the plate 4 is employed without hiring the ink fountain 2 to the ink fountain roller 1 with an appropriate Anstelldruck both with respect to the ink fountain 2 and the ink fountain roller 1. For easy insertion, the bar 6 has at its top a downwardly facing insertion bevel over which the pawl 5 can be easily engaged. The underside of the bar 6 is formed as a slightly upwardly tapered locking surface. The edge located between the insertion bevel and the latching surface ensures the secure holding of the plate 4 by means of the pawl 5. The sealing of the ink cartridge subregions is thus ensured.

An der Unterseite der Platte 4 zum Farbkasten 2 und an dem Teilabschnitt gegenüber den Farbdosierelementen 3 kann je ein gummielastisches Dichteelement - vorzugsweise als ein selbstklebender Streifen - vorgesehen sein.On the underside of the plate 4 to the ink fountain 2 and on the section opposite the paint metering elements 3 may each have a rubber-elastic sealing element - preferably as a self-adhesive strip - be provided.

Weiterhin ist die Platte 4 im Profil keilförmig sich vom Boden des Farbkastens 2 nach oben verjüngend ausgebildet. Mit der Oberfläche der Farbkastenwalze 1 hat die Platte 4 einen keilförmigen Flächenkontakt, so dass sich bei Drehung der Farbkastenwalze 1 ein Rakeleffekt bezüglich der auf der Oberfläche befindlichen Farbe ergibt. So kann keine Druckfarbe in den Kontaktbereich zwischen Platte 4 und Oberfläche der Farbkastenwalze 1 gelangen.Furthermore, the plate 4 is wedge-shaped in profile tapering from the bottom of the ink fountain 2 upwards. With the surface of the ink fountain roller 1, the plate 4 has a wedge-shaped surface contact, so that upon rotation of the ink fountain roller 1, a doctoring effect with respect to the located on the surface Color results. Thus, no ink can get into the contact area between the plate 4 and surface of the ink fountain roller 1.

Die erfindungsgemäße Lösung ermöglicht eine auf einfachste Weise einstellbare Handhabung der Platte 4 sowohl beim Einsetzen in den Farbkasten 2 ohne diesen an- bzw. abstellen zu müssen. Ebenso ist die Platte 4 sehr leicht im Farbkasten positionierbar und dichtet gleichzeitig die Teilbereich sicher gegeneinander ab.The solution according to the invention makes it possible to operate the plate 4 in an easily adjustable way both when inserting it into the ink fountain 2 without having to turn it on or off. Likewise, the plate 4 is very easily positioned in the ink fountain and at the same time reliably seals the partial area against each other.

In den Figuren 3, 3a, 4 und 4a ist die erfindungsgemäße Einrichtung näher erläutert. Jede Platte 4 ist in diesem Fall mit einer Rasteinrichtung 10 gelenkig koppelbar. Dazu ist die Rasteinrichtung 10 einerseits mit einem Stützelement 11 in der Art einer Achse und auf der gegenüberliegenden Seite mit dem an sich bekannten Druckstück als Rastelement 5 ausgebildet. Die Rasteinrichtung 10 ist in der bevorzugten Ausführungsform von der Platte 4 separiert. So kann die Platte 4 frei positionierbar in den Farbkasten 2 eingesetzt werden. Danach wird die Rasteinrichtung 10 mittels der Stützelemente 11 an der Platte 4 eingesetzt und das Rastelement 5 gegen Federkraft an der Leiste 6 eingerastet. So ist die Platte 4 viel besser positionierbar.
Weiterhin kann die Platte 4 unter Zwischenschaltung der Rasteinrichtung 10 an der Leiste 6 fixiert werden. Die Fixierung erfolgt mittels einer Feststelleinrichtung 20. Die Feststelleinrichtung 20 wird mittels einer Klemmschraube 21 an der Leiste 6 geklemmt. Die Leiste 6 ist zur Ausrichtung mit einer Skala 22 und die Feststelleinrichtung 20 mit einer Peilöffnung 23 versehen.
Die Rasteinrichtung 10 wird zur Fixierung an einem Fortsatz 24 der Feststelleinrichtung 20 eingehakt. Dazu sind im Ausführungsbeispiel zwei Rastelemente 5 an jeder Rasteinrichtung 10 angebracht, zwischen die der Fortsatz 24 der Feststelleinrichtung 20 eingefügt und damit fixiert wird. Für die Bedienung ergibt sich der Vorteil, dass die Justierung der Platten 4 voreingestellt werden kann oder dass eine alte Einstellung wiederholt werden kann oder dass mit Entnahme der Leiste 6 samt aller Klemmeinrichtungen 20 die Bedienung des Farbkastens 2 verbessert und zur Neurüstung für den Irisdruck auf einfachste Weise die Justierung der Platten vorbereitet werden kann.In the FIGS. 3, 3a . 4 and 4a the device according to the invention is explained in more detail. Each plate 4 is articulated in this case with a latching device 10. For this purpose, the locking device 10 is formed on the one hand with a support member 11 in the manner of an axis and on the opposite side with the known pressure piece as a locking element 5. The latching device 10 is separated from the plate 4 in the preferred embodiment. Thus, the plate 4 can be used freely positionable in the ink fountain 2. Thereafter, the locking device 10 is inserted by means of the support members 11 on the plate 4 and the locking element 5 is locked against spring force on the bar 6. So the plate 4 is much better positionable.
Furthermore, the plate 4 can be fixed with the interposition of the locking device 10 on the bar 6. The fixing takes place by means of a locking device 20. The locking device 20 is clamped by means of a clamping screw 21 on the bar 6. The bar 6 is provided for alignment with a scale 22 and the locking device 20 with a Peilöffnung 23.
The latching device 10 is hooked for fixing to an extension 24 of the locking device 20. For this purpose, two locking elements 5 are attached to each locking device 10, between which the extension 24 of the locking device 20 inserted and thus fixed in the embodiment. For the operation, there is the advantage that the adjustment of the plates 4 can be preset or that an old setting can be repeated or that with removal of the bar 6 together with all clamping devices 20, the operation of the ink fountain 2 and improves the desecration for the iris print on the simplest Way the adjustment of the plates can be prepared.
