Definitions
- the invention relates to an ink fountain for offset or high-pressure machines with ink metering device which interacts with an ink fountain roller.
- Ink boxes are known in which the side parts are screwed or pinned to the ink box body.
- the purpose of this measure is to prevent the undesired leakage of color in the joining area between the ink knife and the respective ink fountain side part.
- ink fountain side part - which is attached directly to the end of the ink knife and thus directly dependent on it - can no longer prevent the ink from escaping because the necessary adjustment to the Ink fountain roller face, which is required for sealing, is no longer guaranteed due to the too large free space between the ink fountain roller face and the ink fountain side part.
- DE-B 11 62 852 shows a technical teaching in which the end face of the side part facing the ink fountain roller is provided with a recess corresponding to the surface curvature of the ink fountain roller and this end face is placed against the outer surface of the ink fountain roller.
- a sealing material is provided. As long as the side part is in the actual basic position against the roller surface, this prevents the ink from running out.
- the object of the application is to achieve optimization in the areas of adjustability, sealing and manufacturing or assembly costs.
- the advantages that can be achieved with the subject of the application, in addition to increasing the ink fountain seal, are primarily that the manufacturing outlay for the respective individual components is reduced and that the time for completing the ink fountain is also reduced without any restrictions in terms of the sealability.
- Another advantage arises from the almost total negligibility of the heat coefficient, which opens up new perspectives for the material selection.
- the subject of the application allows easy removal of the ink fountain side parts, which is not least important when cleaning the ink fountain.
- Another advantage can be seen in the fact that the adjustment of the ink fountain side part caused by spring force enables the ink fountain to be swiveled slightly to adjust the overall color profile without impairing its function.
- the end face of the ink fountain side part is provided with a recess corresponding to the surface curvature of the ink fountain roller so that the entire end face can be placed against the ink fountain roller, thus preventing the ink from leaking in the entire height region of the ink fountain side part.
- the end face of the ink fountain side part is formed from a lubricant-separating material (plastic) in a further embodiment of the application.
- spring elements are provided in one embodiment of the object of the application, which on the one hand exerts a force directed towards the ink fountain roller - which in particular targets the area below the ink fountain roller axis - and on the other hand exerts a force directed towards the ink fountain knife on the side part and thus preventing the paint from leaking.
- a guide element which has a right angle to the color knife Has guide groove.
- a bolt is embedded in the bottom surface of the guide groove, the ball-shaped head of which is raised to the bottom surface. This ball-shaped bolt end forms the only support point for the ink fountain side part, which also enables the side part to be tilted about this support point.
- the ink fountain roller 1 shown in FIG. 1 is assigned an ink fountain 2 which is arranged such that it can be pivoted away from the ink fountain roller 1 via a pivot point 3.
- the ink fountain 2 is delimited on each of the two end faces by a ink fountain side part 4.
- the end face 12 of the ink fountain side part 4 is provided with a recess corresponding to the surface curvature of the ink fountain roller 1, thereby preventing the ink from leaking in this contacting area.
- the necessary mobility of the ink fountain side part 4 is achieved in that the ink fountain side part 4 is arranged to be movable relative to the ink fountain 2 and the ink fountain roller 1.
- a guide groove 13, which is illustrated in FIG. 2 and is adjacent to the ink knife 11, is provided and serves to receive the ink fountain side part 4.
- the outside of the guide groove 13 forms the guide jaw 5 by two spring elements 10 located at the level of the color knife 11. These spring elements 10 exert a force on the ink fountain side part 4 in such a way that the ink fountain side part 4 is pressed against the ink knife 11.
- the guide groove 13 is wider than the ink fountain side part 4, so that the ink fountain side part has a freedom of movement 15 between the ink knife 11 and guide jaws 5.
- the freedom of movement 15 enables an extended tolerance range in the manufacture of the ink knife 11 and ink fountain side part 4 and ensures the mobility of the ink fountain side part 4 required for tracking the ink fountain 4.
- a bolt 8 is embedded in the bottom surface of the guide groove 13, the end of the bolt being raised to the bottom surface and forming the only support point 9 for the ink fountain side part 4, whereby mobility or tilting of the ink fountain side part 4 around this support point 9 is ensured.
- the ink fountain side part 4 lies securely on the support point 9 in that the force generated by the spring element 6 acts on the region below the axis of the ink fountain roller 1, as a result of which the resulting force is directed onto the support point 9. Furthermore, the existing between the end face 12 of the ink fountain side part 4 and the lateral surface of the ink fountain roller 1 causes an increase in the contact force at the contact point 9.
- a slight pivoting of the ink fountain 2 around the pivot point 3 also causes a pivoting and tracking of the ink fountain side part 4 in the opposite direction around the support point 9, whereby the necessary seal between the end face 12 and the surface of the ink fountain roller 1 is maintained.
- the above-mentioned embodiment represents only one embodiment, in particular it is also possible to provide other types of point supports having the same effect. It would also be conceivable to form the support surface of the ink fountain side part 4 locally as a point support, so that the ink fountain side part 4 only rests on the bottom of the guide groove 13 in this area.
- 6 other adjusting elements can be used instead of the springs, e.g. one or two screws that act on the top of the ink fountain side part 4.
Description
Die Erfindung betrifft einen Farbkasten für Offset- oder Hochdruckmaschinen mit Farbdosiereinrichtung, die mit einer Farbkastenwalze zusammenwirkt.The invention relates to an ink fountain for offset or high-pressure machines with ink metering device which interacts with an ink fountain roller.
Bekannt sind Farbkästen, bei denen die Seitenteile mit dem Farbkastenrumpf verschraubt oder verstiftet sind.Ink boxes are known in which the side parts are screwed or pinned to the ink box body.
Sinn und Zweck dieser Maßnahme ist es, das unerwünschte Austreten von Farbe im Zusammenfügungsbereich zwischen Farbmesser und dem jeweiligen Farbkastenseitenteil zu verhindern.The purpose of this measure is to prevent the undesired leakage of color in the joining area between the ink knife and the respective ink fountain side part.
Das Austreten der Farbe im Zusammenfügungsbereich von Seitenteil und Farbkastenwalze wird in bekannter Weise verhindert, in dem das Seitenteil an die Stirnfläche der Farbkastenwalze angestellt wird.The escape of the ink in the joining area of the side part and the ink fountain roller is prevented in a known manner by placing the side part against the end face of the ink fountain roller.
Wird beispielsweise ein zu langes Farbmesser verwendet, so tritt Farbe im Bereich der Farbkastenwalzenstirnfläche aus, denn das Farbkastenseitenteil - welches unmittelbar am Ende des Farbmessers und damit in unmittelbarer Abhängigkeit von diesem angebracht ist - kann den Farbaustritt nicht mehr verhindern, da die notwendige Anstellung an die Farbkastenwalzenstirnfläche, welche zur Abdichtung erforderlich ist, aufgrund des zu großen Freiraumes zwischen Farbkastenwalzenstirnfläche und Farbkastenseitenteil nicht mehr gewährleistet ist.If, for example, an ink knife that is too long is used, ink will come out in the area of the ink fountain roller end face, because the ink fountain side part - which is attached directly to the end of the ink knife and thus directly dependent on it - can no longer prevent the ink from escaping because the necessary adjustment to the Ink fountain roller face, which is required for sealing, is no longer guaranteed due to the too large free space between the ink fountain roller face and the ink fountain side part.
Im umgekehrten Falle, bei zu kurzem Farbmesser, ist ein Farbaustritt im Bereich des Farbkastenwalzenendes ebenfalls unvermeidlich, da zwischen Farbkastenseitenteil und Farbmesser zwangsläufig ein Spalt entsteht. Zudem kommt noch der Umstand hinzu, daß infolge des zu kurzen Farbmessers das Farbkastenseitenteil zu stark an die Kante von Farbkastenwalzenoberfläche und Farbkastenwalzenstirnfläche gepreßt wird, was zu Beschädigungen (Fressern) führt.In the opposite case, if the ink knife is too short, ink discharge in the area of the ink fountain roller end is also unavoidable, since a gap inevitably arises between the ink fountain side part and the ink knife. In addition, there is the fact that, due to the ink knife being too short, the ink fountain side part comes too close to the edge of Ink fountain roller surface and ink fountain roller end face is pressed, which leads to damage (seizure).
In gleicher weise treten diese Unzulänglichkeiten bei einer Nichtbeachtung der Wärmeausdehnung auf.In the same way, these shortcomings occur when the thermal expansion is not taken into account.
Ferner zeigt beispielsweise die DE-B 11 62 852 eine technische Lehre, bei der die zur Farbkastenwalze gerichtete Stirnfläche des Seitenteiles mit einer, der Oberflachenkrümmung der Farbkastenwalze entsprechenden Ausnehmung versehen und diese Stirnfläche an die Mantelfläche der Farbkastenwalze angestellt ist.Furthermore, DE-B 11 62 852, for example, shows a technical teaching in which the end face of the side part facing the ink fountain roller is provided with a recess corresponding to the surface curvature of the ink fountain roller and this end face is placed against the outer surface of the ink fountain roller.
Um ein Auslaufen der Farbe zwischen dem Seitenteil und der Farbkastenwalzenoberfläche zu verhindern, ist ein Dichtungsmaterial vorgesehen. So lange das Seitenteil in der eigentlichen Grundstellung an die Walzenoberfläche angestellt ist, wird ein Auslaufen der Farbe hierdurch vermieden.In order to prevent the ink from leaking between the side part and the ink fountain roller surface, a sealing material is provided. As long as the side part is in the actual basic position against the roller surface, this prevents the ink from running out.
Bei derartigen Ausgestaltungsformen hat es sich jedoch als nachteilig erwiesen, daß bei einem Abschwenken des Farbkastens auch nur um einen sehr geringen Winkel von der Farbkastenwalze dies zum Farbaustritt an der Kontaktfläche, zwischen der Stirnfläche des Farbkastenseitenteils und der Oberfläche der Farbkastenwalze führt, da das Farbkastenseitenteil, infolge seiner starren Verbindung mit dem Farbkasten, zwangsläufig der Abschwenkbewegung des Farbkastens unterliegt.In such embodiments, however, it has proven to be disadvantageous that when the ink fountain is swiveled away only by a very small angle from the ink fountain roller, this leads to ink leakage at the contact surface between the end face of the ink fountain side part and the surface of the ink fountain roller, since the ink fountain side part, due to its rigid connection to the ink fountain, it is inevitably subject to the swiveling movement of the ink fountain.
Die Möglichkeit der Gesamtverstellung mittels Abschwenken des Farbkastens scheidet demnach aus.The possibility of total adjustment by swiveling the ink fountain is therefore ruled out.
Die bekannten Ausführungsformen erfordern daher
- a) eine hohe Präzision bei der Teilefertigung, d.h. sehr kleine Toleranzvorgaben,
- b) erhöhter Aufwand bei der Materialauswahl, d.h. bei der Farbkastenkonstruktion muß der Wärmeausdehnungskoeffizient der verwendeten Materialien berücksichtigt werden,
- c) erhöhter Aufwand bei der Farbkastenmontage, d.h. Sortierung einzelner Farbkastenkomponenten nach kombinierbaren Toleranzbereichen.
- d) Zugeständnisse an die Verstellmöglichkeiten,d.h. Gesamtfarbverstellung mittels Farbkastenabschwenkung ist nur bei der Ausführung möglich, bei der die Farbkastenseitenteile an der Stirnfläche der Farbkastenwalze anliegen.
- a) high precision in the manufacture of parts, ie very small tolerance specifications,
- b) increased effort in the selection of materials, ie the thermal expansion coefficient of the materials used must be taken into account when designing the ink fountain,
- c) increased effort in the assembly of the ink fountain, ie sorting of individual ink fountain components according to combinable tolerance ranges.
- d) concessions to the adjustment options, ie total ink adjustment by swiveling the ink fountain is only possible in the version in which the ink fountain side parts lie against the end face of the ink fountain roller.
Aufgabe des Anmeldungsgegenstandes ist eine Optimierung in den Bereichen Verstellmöglichkeit, Abdichtung und Herstellungs- bzw. Montagekosten zu erzielen.The object of the application is to achieve optimization in the areas of adjustability, sealing and manufacturing or assembly costs.
Die Aufgabe wird gemäß dem kennzeichnenden Teil des Anspruches 1 gelöst.The object is achieved according to the characterizing part of claim 1.
Die mit dem Anmeldungsgegenstand erzielbaren Vorteile bestehen, neben der Steigerung der Farbkastenabdichtung in erster Linie darin, daß der Fertigungsaufwand für die jeweiligen Einzelkomponenten verringert wird, und daß die Zeit zur Komplettierung des Farbkastens ebenfalls reduziert wird, ohne daß dabei Einschränkungen bei der Abdichtungsfähigkeit entstehen. Ein weiterer Vorteil ergibt sich aus der fast gänzlichen Vernachlässigbarkeit des Wärmekoeffizienten, wodurch sich neue Perspektiven für die Materialauswahl ergeben. Ferner erlaubt der Anmeldungsgegenstand die leichte Demontage der Farbkastenseitenteile, was nicht zuletzt auch bei der Farbkastenreinigung von Bedeutung ist. Ein weiterer Vorteil ist darin zu sehen, daß durch die mit Federkraft bewirkte Anstellung des Farbkastenseitenteiles ein geringes Abschwenken des Farbkastens zur Verstellung des Gesamtfarbprofiles ohne Funktionsbeeinträchtigung ermöglicht wird.The advantages that can be achieved with the subject of the application, in addition to increasing the ink fountain seal, are primarily that the manufacturing outlay for the respective individual components is reduced and that the time for completing the ink fountain is also reduced without any restrictions in terms of the sealability. Another advantage arises from the almost total negligibility of the heat coefficient, which opens up new perspectives for the material selection. Furthermore, the subject of the application allows easy removal of the ink fountain side parts, which is not least important when cleaning the ink fountain. Another advantage can be seen in the fact that the adjustment of the ink fountain side part caused by spring force enables the ink fountain to be swiveled slightly to adjust the overall color profile without impairing its function.
In einer weiteren Ausgestaltung des Anmeldungsgegenstandes ist die Stirnseite des Farbkastenseitenteils mit einer der Oberflächenkrümmung der Farbkastenwalze entsprechenden Ausnehmung versehen, so daß die gesamte Stirnseite an die Farbkastenwalze angestellt werden kann, womit ein Auslaufen der Farbe im ganzen Höhenbereich des Farbkastenseitenteils verhindert wird.In a further embodiment of the object of the application, the end face of the ink fountain side part is provided with a recess corresponding to the surface curvature of the ink fountain roller so that the entire end face can be placed against the ink fountain roller, thus preventing the ink from leaking in the entire height region of the ink fountain side part.
Zur Verminderung des Reibschlußes zwischen der Stirnfläche des Farbkastenseitenteiles und der Mantelfläche der Farbkastenwalze, ist in einer weiteren Ausgestaltung des Anmeldungsgegenstandes die Stirnfläche des Farbkastenseitenteiles aus einem schmierstoffabsondernden Material (Kunststoff) gebildet.In order to reduce the frictional connection between the end face of the ink fountain side part and the outer surface of the ink fountain roller, the end face of the ink fountain side part is formed from a lubricant-separating material (plastic) in a further embodiment of the application.
Zur Aufrechterhaltung der Kontaktierung zwischen Farbkastenseitenteil, Farbmesser und Farbkastenwalze sind in einer Ausbildungsform des Anmeldungsgegenstandes Federelemente vorgesehen, die einerseits eine zur Farbkastenwalze gerichtete Kraft - die insbesondere auf den Bereich unterhalb der Farbkastenwalzenachse zielt - und andererseits eine auf das Farbmesser gerichtete Kraft auf das Seitenteil ausüben und somit das Auslaufen der Farbe verhindern.In order to maintain contact between the ink fountain side part, ink knife and ink fountain roller, spring elements are provided in one embodiment of the object of the application, which on the one hand exerts a force directed towards the ink fountain roller - which in particular targets the area below the ink fountain roller axis - and on the other hand exerts a force directed towards the ink fountain knife on the side part and thus preventing the paint from leaking.
Bei einer weiteren Ausbildungsform des Anmeldungsgegenstandes ist ein Führungselement vorgesehen, welches eine rechtwinklig zum Farbmesser verlaufende Führungsnut aufweist. In der Bodenfläche der Führungsnut ist ein Bolzen eingelassen, dessen ballenförmiger Kopf erhaben zur Bodenfläche ist. Dieses ballenförmige Bolzenende bildet den einzigen Auflagepunkt für das Farbkastenseitenteil, wodurch auch ein Kippen des Seitenteiles um diesen Auflagepunkt ermöglicht wird.In a further embodiment of the subject of the application, a guide element is provided which has a right angle to the color knife Has guide groove. A bolt is embedded in the bottom surface of the guide groove, the ball-shaped head of which is raised to the bottom surface. This ball-shaped bolt end forms the only support point for the ink fountain side part, which also enables the side part to be tilted about this support point.
Ein Ausführungsbeispiel des Anmeldungsgegenstandes ist in der Zeichnung dargestellt und wird mittels Figur 1 und Figur 2 näher beschrieben.An embodiment of the subject of the application is shown in the drawing and is described in more detail by means of Figure 1 and Figure 2.
Der in Figur 1 dargestellten Farbkastenwalze 1 ist ein Farbkasten 2 zugeordnet, der über einen Drehpunkt 3 von der Farbkastenwalze 1 abschwenkbar angeordnet ist.The ink fountain roller 1 shown in FIG. 1 is assigned an
Die Begrenzung des Farbkastens 2 an den beiden Stirnseiten erfolgt durch jeweils ein Farbkastenseitenteil 4.The
Die Stirnfläche 12 des Farbkastenseitenteiles 4 ist mit einer der Oberflächenkrümmung der Farbkastenwalze 1 entsprechenden Ausnehmung versehen, wodurch ein Auslaufen der Farbe in diesem Kontaktierungsbereich verhindert wird.The
Die Feder 6, welche an ihrem einen Ende durch die Schraube 7 mit dem Farbkasten 2 verbunden ist, übt eine auf den Bereich unterhalb der Farbkastenwalzenachse zielende Kraftwirkung auf das Farbkastenseitenteil 4 derart aus, daß dieses Farbkastenseitenteil 4 mit seiner Stirnfläche 12 an die Farbkastenwalze 1 angepreßt wird; wodurch die Abdichtung zwischen der Oberfläche der Farbkastenwalze 1 und der Stirnfläche 12 des Farbkastenseitenteiles 4 erhalten bleibt.The spring 6, which is connected at one end by the
Ein leichtes Abschwenken des Farbkastens 2 um den Drehpunkt 3, zur Gesamtfarbverstellung, beeinträchtigt die Abdichtung im Bereich der Stirnfläche 12 des Seitenteiles 4 und der Oberfläche der Farbkastenwalze 1 nicht, da das Farbkastenseitenteil 4, durch die Kraftwirkung der Feder 6, nachgeführt wird und angestellt bleibt. Die dazu notwendige Beweglichkeit des Farbkastenseitenteiles 4 wird erzielt, indem das Farbkastenseitenteil 4 beweglich zum Farbkasten 2 und zur Farbkastenwalze 1 angeordnet ist. Zur Erzielung dieser Beweglichkeit ist eine in Figur 2 verdeutlichte, an das Farbmesser 11 angrenzende Führungsnut 13 vorgesehen, die der Aufnahme des Farbkastenseitenteiles 4 dient.A slight swiveling of the
Das Farbkastenseitenteil 4 liegt planflächig an seiner zum Farbkasteninneren gerichteten Seite am Farbmesser 11 an, wodurch die Abdichtung des Farbkastens 2 in diesem Stirnbereich des Farbkastens 2 erzielt wird.The ink fountain side part 4 lies flat on its side facing the ink fountain interior against the
Die Außenseite der Führungsnut 13 bildet der Führungsbacken 5, indem zwei in Höhe des Farbmessers 11 befindliche Federelemente 10 angeordnet sind. Diese Federelemente 10 üben eine Kraftwirkung auf das Farbkastenseitenteil 4 derart aus, daß das Farbkastenseitenteil 4 an das Farbmesser 11 angepreßt wird.The outside of the
Die Führungsnut 13 ist breiter als das Farbkastenseitenteil 4, so daß das Farbkastenseitenteil einen Bewegungsfreiraum 15 zwischen Farbmesser 11 und Führungsbacken 5 aufweist. Der Bewegungsfreiraum 15 ermöglicht einen erweiterten Toleranzbereich bei der Fertigung von Farbmesser 11 und Farbkastenseitenteil 4 und gewährleistet die für eine Nachführung des Farbkastens 4 erforderliche Beweglichkeit des Farbkastenseitenteiles 4.The
In der Bodenfläche der Führungsnut 13 ist ein Bolzen 8 eingelassen, wobei das Ende des Bolzens zur Bodenfläche erhaben angeordnet ist und den einzigen Auflagepunkt 9 für das Farbkastenseitenteil 4 bildet, wodurch eine Beweglichkeit bzw. ein Kippen des Farbkastenseitenteils 4 um diesen Auflagepunkt 9 gewährleistet ist.A
Ein sicheres Aufliegen des Farbkastenseitenteiles 4 auf dem Auflagepunkt 9 wird erreicht, indem die vom Federelement 6 erzeugte Kraft auf den Bereich unterhalb der Achse der Farbkastenwalze 1 wirkt, wodurch die daraus resultierende Kraft auf den Auflagepunkt 9 gerichtet wird. Ferner bewirkt der zwischen der Stirnfläche 12 des Farbkastenseitenteiles 4 und der Mantelfläche der Farbkastenwalze 1 bestehende Reibschluß eine Verstärkung der Auflagekraft am Auflagepunkt 9.The ink fountain side part 4 lies securely on the support point 9 in that the force generated by the spring element 6 acts on the region below the axis of the ink fountain roller 1, as a result of which the resulting force is directed onto the support point 9. Furthermore, the existing between the
Ein leichtes Abschwenken des Farbkastens 2 um den Drehpunkt 3 bewirkt gleichzeitig auch ein Abschwenken und Nachführen des Farbkastenseitenteiles 4 in entgegengesetzte Richtung um den Auflagepunkt 9, wodurch die nötige Abdichtung zwichen der Stirnfläche 12 und der Oberfläche der Farbkastenwalze 1 erhalten bleibt.A slight pivoting of the
Das obengenannte Ausführungsbeispiel stellt lediglich eine Ausführungsform dar, insbesondere ist es auch möglich, andere gleichwirkende Arten von Punktauflagen vorzusehen. Denkbar wäre auch die Auflagefläche des Farbkastenseitenteiles 4 örtlich als Punktauflage auszubilden, so daß das Farbkastenseitenteil 4 nur in diesem Bereich auf dem Boden der Führungsnut 13 aufliegt.The above-mentioned embodiment represents only one embodiment, in particular it is also possible to provide other types of point supports having the same effect. It would also be conceivable to form the support surface of the ink fountain side part 4 locally as a point support, so that the ink fountain side part 4 only rests on the bottom of the
Ebenso können statt der Federn 6 andere Anstellelemente zum Einsatz kommen, z.B. eine oder zwei Schrauben die auf die Oberseite des Farbkastenseitenteiles 4 einwirken.Likewise, 6 other adjusting elements can be used instead of the springs, e.g. one or two screws that act on the top of the ink fountain side part 4.
