Farbauftragvorrichtung insbesondere für RotationsdruckmaschinenInk application device, in particular for rotary printing machines

Die Neuerung betrifft eine Farbauftragvorrichtung insb. für -Botationsdruckmaschinen, bei welcher die Farbe mittels Pumpen in einen an der Farbübertragwalze anliegenden sog. Farbbalken .gefördert wird, der von der Walze absehwenkbar angeordnet ist.The innovation relates to an ink application device, especially for -botation printing machines, in which the ink is pumped into what is known as an ink bar resting on the ink transfer roller . Is conveyed, which is arranged so that it can be pivoted away from the roller.

Für die gleichmäßige Auftragung der Druckfarbe auf die Farb- - übertragwalze der Farbwerke von Botations-Druckmaschinen werden u.a. auch sogenannte Farbbalken verwendet, in welche zahlreiche taschenartige Vertiefungen eingefräst sind, mittels welcher die durch Pumpen zugeführte Farbe durch sehr schmale Öffnungen geringen Querschnittes auf die Farbübertragw&ize aufgetragen wird. Für eine gleichmäßige Auftragung und Verteilung auf die Farbüberträgwalze muß der Abstand zwischen Balkenauftragfläche und Farbübertragwalze entsprechend klein und mit einem keilartigen Querschnitt gehalten werden. Diese engen Durchgänge werden gedoch häufig von festen Bestandteilen, die sich in der Farbe befinden verstopft. Außerdem setzt sich auch der auf der Papierbahn befindliche Papierstaub auf die Druckplatten ab, wird.von den Auftragwalzen übernommen undwandert entgegen . dem Farbfluß zur Farbübertragwalze. Auch diese Schmutzteilchen verringern verhältnismäßig schnell die Spalte, was Störungen in der Farbgebung und unbrauchbare Druckexemplare zur Folge hat.For the even application of the printing ink to the ink - Transfer rollers of the inking units of Botations printing machines are also used, among other things, so-called color bars, in which numerous pocket-like recesses are milled, by means of which the paint supplied by pumps through very narrow Openings with a small cross-section applied to the ink transfer tool will. For an even application and distribution on the ink transfer roller, the distance between the bar application surface must be and ink transfer roller are kept correspondingly small and with a wedge-like cross-section. These narrow passages are often made up of solid components that are in the paint are clogged. In addition, the Any paper dust on the paper web falls on the printing plates, is taken over by the applicator rollers and moves towards it. the ink flow to the ink transfer roller. These dirt particles also reduce the gaps relatively quickly, which causes problems in the coloring and unusable print copies result.

Bei modernen Schnellaufenden Maschinen erwärmen sich zudem.die Farbwerkwalzen auch erheblich bis zu Temperaturen von etwa 5o bis 6o G. Demzufolge quellen die Walzenbezüge und rufen durch die; größere Walkarbeit eine weitere Temperatursteigerung hervor, welche sich wiederum auf den Farbbalken überträgt und zwar umso mehr als die Farben durch die steigende ErwärmungIn modern high-speed machines, the inking unit rollers also heat up considerably up to temperatures of around 5o to 6o G. As a result, the roller covers swell and call through the ; Greater flexing work results in a further increase in temperature, which in turn is transferred to the color bar, all the more so than the colors due to the increasing warming

Eine weitere Erwärmung tritt zudem durch das Zusetzen der Spalte ein, so daß eine Verformung des Farbbalkens erfolgt und die Gefahr besteht, daß sich der kleine keilartige Querschnitt zwischen Farbbalken und Farbübertragwalze "verändert. Um diesen Mangel zu beheben, muß der Anfall von Wärme am Farbbalken nach- Möglichkeit.verhindert bzw. dieselbe abgeführt werden. Dies kann bei einer Farbauftragvorrichtung, der'eingangs erwähnten Art nach der Feuerung dadurch geschehen, daß in der Nähe der Taschen in den Farbbalken.Hohlräume angeordnet sindj durch welche Kühlflüssigkeit temperaturregelnd geleitet wird.

Further warming also occurs due to the clogging of the gaps a, so that a deformation of the color bar takes place and the There is a risk that the small wedge-like cross-section between the ink bar and the ink transfer roller will change The deficiency must be remedied by the build-up of heat on the color bar as far as possible. prevented or the same can be removed. This can be done in the case of a paint application device, which was mentioned at the beginning Kind of done after firing in that in the vicinity of the pockets in the Farbbalken.Hohlraum are arranged through which cooling liquid is passed to regulate the temperature. This measure eliminates the need to readjust the color bar as a result of its different levels caused by soiling !Temperature. -.

In der Bähe der der Zuführung der Farbe dienenden Taschen des Oberteils Λ und des Unterteils 2 sind vorzugsweise Längsbohrungen 27 zum Durchleiten von Kühlflüssigkeit vorgesehen.

"In the vicinity of the pockets of the upper part Λ and the lower part 2, which are used to supply the paint, longitudinal bores 27 are preferably provided for the passage of cooling liquid. The connection between the individual parts of the upper or lower part of this longitudinal bore can be made by flexible hoses. The cavities 27 are expediently arranged as close as possible to the end face of the bars lying against the ink transfer roller 8. "
