Abstract

An ink fountain for a printing press has a temperature-responsive element for compensating the adjustment of the spacing between the blade and the fountain roller to keep the thickness of the ink film fed by the blade substantially constant even under extreme temperature variations. The sub-frame of the ink fountain is pivotally mounted to the main frame of the printing press about a pivot axis generally parallel to the axis of the fountain roller, and the pivot angle is a function of the thermal expansion of the temperature-responsive element. In one preferred embodiment, the temperature-responsive element is elongated, received in a guide fixed to the sub-frame, and has a free end bearing against the bearing bushing of the fountain roller. In another embodiment, the temperature-responsive element is a side wall of the ink trough or is a plate parallel to the side wall of the ink trough, and rollers are journaled to the temperature-responsive element and bear against the surface of the fountain roller. In either embodiment, the temperature-responsive element is pre-stressed by a pull rod tending to pivot the sub-frame so that the temperature-responsive element bears against the sub-frame and the main frame.

Description

Die Erfindung betrifft einen Farbkasten für Druckmaschinen, mit verstellbaren Dosierelementen, der gegenüber einem Farbduktor einstellbar verschwenkbar auf einer Achse gelagert ist, wobei dieser an Druckmaschinenseitenteilen gehaltert ist.The invention relates to an ink fountain for printing machines, with adjustable metering elements, which is mounted such that it can be pivoted relative to a ink fountain roller on an axis, the latter being held on parts of the printing machine.

Es sind die unterschiedlichsten Vorrichtungen zum genauen Einstellen des Farbkastens bzw. der Farbmesser oder Farbschieber bekannt geworden. Je genauer die Einstellung bzw. die Justierung zum Farbduktor ist, desto präziser kann die gewünschte Farbdicke eingehalten werden, dies ist für einen Druckvorgang wesentlich.A wide variety of devices for precisely adjusting the ink fountain or the color knife or color slide have become known. The more precise the adjustment or adjustment to the ink duct, the more precisely the desired ink thickness can be maintained, which is essential for a printing process.

Die DE-AS 1 942 732 zeigt hierzu einen Farbkasten für Druckmaschinen mit Farbmessern und Zonenschrauben, der gegenüber einem Farbduktor einstellbar verschwenkbar von einer Achse getragen wird. Der Schwerpunkt des Farbkastens ist so gewählt, daß dieser gegen einen Anschlag des Maschinengestells anliegt.DE-AS 1 942 732 shows an ink fountain for printing presses with ink knives and zone screws, which is pivotably supported by an axis relative to a ink fountain pen. The focus of the ink fountain is chosen so that it rests against a stop on the machine frame.

Durch diese Anordnung wird die Aufgabe gelöst, eine Einstellmöglichkeit für das Farbprofil, Farbspalt und Anstellwinkel eines Farbkastens unter Beibehaltung der Stützlinie zwischen Farbmessern und Farbprofilhebeln zu schaffen.With this arrangement, the object is achieved to create a setting option for the color profile, color gap and angle of attack of a color box while maintaining the support line between color knives and color profile levers.

In der Druckereipraxis hat sich nun aber gezeigt, daß, je genauer die obengenannte Justiermöglichkeit ist, die Temperaturschwankungen an Druckmaschinen während einer oder mehrerer Betriebsschichten dazu führt. daß die Farbschichtdicke auf dem Farbduktor unterschiedlich ist.In printing practice, however, it has now been shown that the more precise the above-mentioned adjustment option is, the temperature fluctuations on printing presses during one or more operating shifts lead to this. that the ink layer thickness on the ink roller is different.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Farbschichtdicke auf dem Farbduktor auch bei extremen Temperaturänderungen der Druckmaschine konstant zu halten.Starting from this prior art, the invention is based on the object of keeping the ink layer thickness on the ink ductor constant even in the event of extreme temperature changes in the printing press.

Die Lösung der gestellten Aufgabe wird bei einem Farbkasten für Druckmaschinen der Eingangs genannten Art dadurch erreicht, daß am Farbkasten verstellbar geführte Distanzausgleichselemente befestigt sind, welche einen Ausdehnungskoeffizienten größer als Stahl aufweisen, daß die Distanzausgleichselemente mittels gefederten Zugstangen, die an Druckmaschinenseitenteilen abgestützt und am Farbkasten gehaltert sind, unter konstanter Kraft gegen eine zylindrische Oberfläche in seitlichen Endbereichen des Farbduktors anpreßbar sind, und daß die Zugstangen im Bereich von Tellerfedern mittels Gewindebolzen verriegelbar sind.The solution to the problem is achieved in an ink fountain for printing presses of the type mentioned in that adjustably guided distance compensation elements are attached to the ink fountain, which have an expansion coefficient greater than steel, that the distance compensation elements are supported by spring-loaded tie rods, which are supported on the press side and held on the ink fountain are, can be pressed under constant force against a cylindrical surface in lateral end areas of the ink ductor, and that the tie rods can be locked in the area of disc springs by means of threaded bolts.

Am Farbkasten sind verstellbar geführte Distanzausgleichselemente befestigt, die einen Ausgleichskoeffizienten größer als Stahl aufweisen. Als Distanzausgleichselemente bieten sich unterschiedliche Ausführungen an, je nach dem für welche der Druckmaschinen das Distanzausgleichselement verwendet werden soll..Adjustable distance compensation elements are attached to the ink fountain, which have a compensation coefficient greater than steel. Different versions are available as distance compensation elements, depending on which of the printing presses the distance compensation element is to be used for.

Die Distansausgleichselemente gleichen durch ihre Aus-, dehnung Temperaturunterschiede der Druckmaschine aus. Einmal eingestellte Dosierelemente behalten so über längere Betriebszeiten eine konstante Entfernung zum Farbduktor.The distance compensating elements compensate for temperature differences of the printing press due to their expansion. Once the dosing elements have been set, they remain at a constant distance from the ink ductor over longer operating times.

Die Ausdehnung bzw. Schrumpfung der Distanzausgleichselemente richtet sich nach den Temperaturschwankungen.The expansion or contraction of the distance compensation elements depends on the temperature fluctuations.

Um den Spalt auch bei den unterschiedlichen Werkstoffen der umliegenden Bauteile der Druckmaschine, sowie deren unterschiedlichen Temperaturen, konstant zu halten haben sich Messing und Aluminium besonders gut bewährt.In order to keep the gap constant even with the different materials of the surrounding components of the printing press and their different temperatures, brass and aluminum have proven particularly effective.

Die Distanzausgleichselemente sind mittels gefederten Zugstangen, die an Druckmaschinenseitenteilen abgestützt und am Farbkasten gelagert sind, unter konstanter Kraft gegen eine zylindrische Oberfläche in seitlichen Endbereichen des Farbduktors anpreßbar. Die Tellerfedern werden mittels eines Drehmomentenschlüssels über einen Sterngriff bei der Montage oder Reparatur jeweils auf einen vorgegebenen Wert eingestellt. Nach der genauen Einstellung der Vorspannung der Federkräfte, wird der Gewindebolzen als mechanischer Anschlag justiert.The distance compensation elements can be pressed under constant force against a cylindrical surface in lateral end areas of the ink ductor by means of spring-loaded tie rods, which are supported on the printing machine side parts and are mounted on the ink fountain. The plate springs are set to a specified value using a torque wrench and a star grip during assembly or repair. After the exact setting of the preload of the spring forces, the threaded bolt is adjusted as a mechanical stop.

Je dichter die Distanzausgleichselemente an beiden Seiten der Farbmesser vorgesehen sind, desto kleiner ist die Durchbiegung am Farbduktor. Dies führt aber dazu, daß Rollen zur Abstützung der Vorspannkraft am Farbduktor vorzusehen sind.The closer the distance compensation elements are on both sides of the ink knife, the smaller the deflection at the ink duct. However, this means that rollers must be provided to support the pre-tensioning force on the ink duct.

In besonders vorteilhafterweise werden die Farbkastenseitenwände selbst als Distanzausgleichselemente verwendet. Es können aber auch zusätzlich auf die Farbkastenseitenwände eine gleich große Platte mit einem Ausdehnungskoeffizienten größer als Stahl aufgeschraubt werden, an denen Anschlagrollen befestigt sind.In a particularly advantageous manner, the ink fountain side walls themselves are used as distance compensation elements. However, an equally large plate with an expansion coefficient greater than steel can also be screwed onto the ink fountain side walls, to which stop rollers are attached.

Eine weitere Ausführung vermeidet Reibungskräfte, in dem sie die Distanzausgleichselemente gegen die zylindrischen Lagerschalen des Farbduktors abstützen.Another version avoids frictional forces by supporting the distance compensation elements against the cylindrical bearing shells of the ink ductor.

Die Zugstangen sind im Bereich von Tellerfedern mittels Gewindebolzen verriegelbar. In besonders vorteilhafterweise bleibt damit die mittels des Drehmomentenschlüssels eingestellte Vorspannung mit den Distanzausgleichselementen konstant erhalten.The tie rods can be locked in the area of disc springs using threaded bolts. In a particularly advantageous manner, the pretension set by means of the torque wrench with the distance compensation elements is thus maintained constant.

An den Distanzausgleichselementen ist, in dem Farbduktor überdeckenden Bereich, eine abdichtende und temperaturausgleichende Filzeinlage befestigt.A sealing and temperature-compensating felt insert is attached to the distance compensation elements in the area covering the ink duct.

Die Praxis hat gezeigt, daß selbst über die Länge des Farbduktors Temperaturunterschiede auftreten können. Um diese zu vermeiden bzw. auszugleichen, sind bei der Ausführung "Abstützung am Farbduktor" in besonders einfacherweise Filzeinlagen vorgesehen. Diese Filzeinlagen übernehmen neben der vorteilhaften Temperaturvergleichmäßigung zugleich eine Abdichtfunktion am Farbduktor.Practice has shown that temperature differences can occur even over the length of the color duct. In order to avoid or compensate for this, felt inserts are provided in a particularly simple manner in the "support on the ink duct" version. In addition to the advantageous temperature equalization, these felt inserts also perform a sealing function on the ink duct.

Die Figur 1 zeigt einen Teilbereich einer Druckmaschine 1 mit einem Farbkasten 2 und darauf befindlichen Dosierelementen 3 im Bereich eines Farbduktors 4 in der Seitenansicht. Der Farbkasten 2 ist schwenkbar auf einer Achse 5 gelagert. In Farbschieberebene 3.1 ist ein Distanzausgleichselement 9, das in Form einer Stange 17 ausgeführt ist, in einer Führung 18 verstellbar angeordnet. Die Führung 18 ist mit Schrauben 9.2, 9.3 über eine spezielle Halterung 2.1 am Farbkasten 2 befestigt. Die Halterung 2.1 ist seitlich am Farbkasten 2 ebenfalls um die Achse 5 drehbar angeordnet.1 shows a partial area of a printing press 1 with an ink fountain 2 and metering elements 3 located thereon in the area of an ink ductor 4 in a side view. The ink fountain 2 is pivotally mounted on an axis 5. In the color slide plane 3.1, a distance compensation element 9, which is designed in the form of a rod 17, is adjustably arranged in a guide 18. The guide 18 is fastened to the ink fountain 2 with screws 9.2, 9.3 via a special holder 2.1. The holder 2.1 is also arranged laterally on the ink fountain 2 so as to be rotatable about the axis 5.

Die Stange 17 ist in der Führung 18 durch leichtes Verdrehen um kleinste Differenzbeträge verstellbar. Beim Justiervorgang schwenkt der ganze Farbkasten 2 um die Achse 5 und verändert damit den Spalt zum Farbduktor 4.The rod 17 is adjustable in the guide 18 by slight twisting by the smallest difference. During the adjustment process, the entire ink fountain 2 swivels about the axis 5 and thus changes the gap to the ink duct 4.

Nach dem Justiervorgang wird die Stange 17 mit einer Schraube 9.1 in der Führung 18 fixiert.After the adjustment process, the rod 17 is fixed in the guide 18 with a screw 9.1.

Am Farbkasten 2 greift eine Zugstange 10 in einer kleinen Entfernung zur Achse 5 an. Die Zugstange 10 ist über einer Anlagefläche 10.1 an nicht dargestellten Druckmaschinenseitenteilen 6 über Tellerfedern 13 abgestützt. Die Tellerfedern 13 sind in Federhaltern 20 geführt. Am frei liegenden Ende der Zugstange 10 ist ein Sterngriff 10.3 im Bereich der Tellerfedern 13 angeordnet, der einen Gewindebolzen 14 aufweist. Der Gewindebolzen 14 wirkt bei Einstellung als Endanschlag der Zugstange 10.A drawbar 10 engages the ink fountain 2 at a short distance from the axis 5. The pull rod 10 is supported over a contact surface 10.1 on printing machine side parts 6, not shown, via plate springs 13. The plate springs 13 are guided in spring holders 20. At the exposed end of the pull rod 10, a star grip 10.3 is arranged in the area of the plate springs 13, which has a threaded bolt 14. When set, the threaded bolt 14 acts as an end stop of the pull rod 10.

Nachdem mit einem Drehmomentenschlüssel die Vorspannung über die Stange 17 auf die Lagerschale 4.1 eingestellt ist, wird mittels des Gewindebolzens 14 die Zugstange 10 verriegelt.After the pretension has been set on the bearing shell 4.1 via the rod 17 using a torque wrench, the pull rod 10 is locked by means of the threaded bolt 14.

Die Figur 2 zeigt in der Draufsicht den gleichen Ausschnitt der Druckmaschine 1 wie die Figur 1.FIG. 2 shows a top view of the same section of the printing press 1 as FIG. 1.

Die Lagerschale 4.1 des Farbduktors 4 ist wie die Anlagefläche 10.1 an einem Druckmaschinenseitenteil 6 gehaltert. Bei dieser Ausführung des Distanzausgleichselementes 9 ist besonders gut in der Draufsicht zu erkennen, daß die Wirkrichtung der Zugstange 10 nur leicht versetzt zur Wirkrichtung des Distanzausgleichselementes 9. ist. Es können somit keine großen Momente bei der Vorspannung der Stange 17 entstehen. Wiederum können, da keine Reibungskräfte zwischen der Stange 17 und der Oberfläche 11 der Lagerschale 4.1 auftreten, große Kräfte zur Vorspannung übertragen werden.The bearing shell 4.1 of the ink ductor 4, like the contact surface 10.1, is held on a printing machine side part 6. In this embodiment of the distance compensation element 9 it can be seen particularly well in the plan view that the direction of action of the pull rod 10 is only slightly offset from the direction of action of the distance compensation element 9. Thus, no large moments can arise during the pretensioning of the rod 17. Again, since there are no frictional forces between the rod 17 and the surface 11 of the bearing shell 4.1, large forces can be transmitted for pretensioning.

Die Tellerfedern 13 im Bereich der Anlagefläche 10.1 sorgen nach einmaliger Einstellung mit dem Drehmomentenschlüssel für die oben genannte konstante Vorspannung der Stange 17.The disc springs 13 in the area of the contact surface 10.1 After a single adjustment with the torque wrench, ensure the above-mentioned constant preloading of the rod 17.

Figur 3 zeigt eine Seitenansicht ähnlich der Figur 1 mit einer anderen Ausführung des Distanzausgleichselementes 7. Das Distanzausgleichselement 7 ist die seitlich am Farbkasten 2 vorhandene Farbkastenseitenwand 15. Um eine seitliche Anlage auf dem Farbduktor 4 zu erreichen sind zwei Anschlagrollen 16 an den Farbkastenseitenwänden 15 befestigt.FIG. 3 shows a side view similar to FIG. 1 with a different embodiment of the distance compensation element 7. The distance compensation element 7 is the ink fountain side wall 15 on the side of the ink fountain 2. Two stop rollers 16 are attached to the ink fountain side walls 15 in order to make lateral contact on the ink fountain 4.

Die Zugstange 10 ist besonders günstig mittig zwischen den beiden Anschlagrollen 16 in Druckrichtung der Farbkastenseitenwand 15 angeordnet. Die Anlagefläche 10.2 ist am Farbkasten 2 verschraubt. Die Vorspannung über die Zugstange 10 wird ähnlich der ersten Version mittels Tellerfedern 13 in Federhaltern 20 konstant gehalten, genau wie die Verriegelung der Zugstange 10 mittels des Gewindebolzens 14. Im Berührungsbereich zwischen Farbduktor 4 und Farbkastenseitenwand 15 ist zum Abdichten eine Filzeinlage 19 befestigt.The pull rod 10 is particularly advantageously arranged centrally between the two stop rollers 16 in the pressure direction of the ink fountain side wall 15. The contact surface 10.2 is screwed to the ink fountain 2. The pretensioning via the pull rod 10 is kept constant, similar to the first version, by means of plate springs 13 in spring holders 20, just like the locking of the pull rod 10 by means of the threaded bolt 14. In the area of contact between the ink duct 4 and the ink box side wall 15, a felt insert 19 is fastened for sealing.

Figur 4 zeigt die Draufsicht der Figur 3. Der Farbkasten 2 ist auf der Achse 5 in dem Druckmaschinenseitenteil 6 gelagert.FIG. 4 shows the top view of FIG. 3. The ink fountain 2 is mounted on the axis 5 in the printing machine side part 6.

Die Anlagefläche 10.2 ist am Farbkasten 2 verschraubt. Das Ende der Zugstange 10 ist an dem Druckmaschinenseitenteil 6 gelagert. Die Zugstange 10 kann somit ähnlich der ersten Ausführung den Spalt zum Farbduktor 4 einstellen. Eine dritte sehr einfache Ausführungsform besteht darin, daß die Distanzausgleichselemente 8 in Form der Farbkastenseitenwände 15 aus einem Messing-oder Aluminiummaterial gefertigt werden und parallel zu der Farbkastenseitenwand 15 auf diese aufgeschraubt werden. In diesem Falle sind die Anschlagrollen 16 an den Distanzausgleichselementen 8 befestigt.The contact surface 10.2 is screwed to the ink fountain 2. The end of the pull rod 10 is mounted on the printing machine side part 6. The pull rod 10 can thus set the gap to the ink duct 4 similar to the first embodiment. A third very simple embodiment consists in that the distance compensation elements 8 in The shape of the ink fountain side walls 15 are made of a brass or aluminum material and are screwed onto the ink fountain side wall 15 parallel to the latter.
