Description

Die Erfindung betrifft einen Farbkasten für eine Druckmaschine mit einer für diesen die vordere Begrenzung bildenden Farbkastenwalze, einem in Richtung der Achse der Farbkastenwalze (1) verlaufenden Farbmesser und senkrecht zur Achse der Farbkastenwalze stehenden, am Farbmesser anliegenden Seitenwänden, die jeweils aus einem an der Farbkastentraverse befestigten Hauptteil und einem an diesem befestigten mit einer der Krümmung des Farbkastenwalzenmantels angepaßten Stirnfläche an die Farbkastenwalze dichtend anstellbaren vorderen Teil bestehen.The invention relates to an ink fountain for a printing press with an ink fountain roller forming the front boundary for it, an ink knife running in the direction of the axis of the ink fountain roller (1) and perpendicular to the axis of the ink fountain roller, the side walls adjoining the ink knife, each of which consists of a on the ink fountain crossmember attached main part and an attached to this with one of the curvature of the ink fountain roller jacket adapted face to the ink fountain roller adjustable front part.

Durch die DE-B-1 162 852 ist ein Farbkasten für eine Druckmaschine der vorangehend spezifizierten Gattung bekannt geworden, bei der die senkrecht zur Achse der Farbkastenwalze stehenden Seitenwände an den der Farbkastenwalze gegenüberliegenden Kanten jeweils mit einem Lagerschuh ausgestattet sind, der mit einer der Krümmung der Farbkastenwalze angepaßten Fläche elastisch an dieser anliegt, so daß infolge von Erwärmungsvorgängen auftretende Längenänderungen der Farbkastenwalze keinen Einfluß auf die Dichtungsstellen zwischen den genannten Lagerschuhen und der Farbkastenwalze haben. Längenänderungen am Farbmesser jedoch führen bei diesem bekannten Farbkasten zu Dichtungsproblemen zwischen den Enden des Farbmessers und der jeweiligen Seitenwand.From DE-B-1 162 852, an ink fountain for a printing machine of the type specified above has become known, in which the side walls perpendicular to the axis of the ink fountain roller are each equipped with a bearing shoe on the edges opposite the ink fountain roller, which has one of the curvatures the surface of the ink fountain roller rests elastically on it, so that changes in length of the ink fountain roller due to heating processes have no influence on the sealing points between the bearing shoes and the ink fountain roller. However, changes in the length of the ink knife lead to sealing problems in this known ink fountain between the ends of the ink knife and the respective side wall.

Aufgabe der Erfindung ist es, einen Farbkasten mit einer radialen Farbkastenabdichtung auszustatten, bei dem sowohl Längenänderungen der Farbkastenwalze als auch des Farbmessers keine Leckstellen verursachen.The object of the invention is to provide an ink fountain with a radial ink fountain seal in which changes in length of the ink fountain roller and the ink knife do not cause any leaks.

Diese Aufgabe wird dadurch gelöst, daß das plattenförmige sich über die Farbkastentiefe erstreckende Hauptteil im vorderen an das Farbmesser angrenzenden Bereich eine Ausnehmung in einer Ebene parallel zur Stirnseite der Farbkasten walze aufweist, die durch das an seiner Innenseite und an der Farbkastenwalze anliegende plattenförmige vordere Teil überdeckt wird, und daß eine in der dem Farbmesser zugewandten Stirnseite des Hauptteils in einer Nut angeordnete Dichtung mit ihrem vorderen in der Ausnehmung verlaufenden Ende unter Anlage an dem Farbmesser an das vordere Teil preßbar ist. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen.This object is achieved in that the plate-shaped main part extending over the ink fountain depth in the front area adjacent to the ink knife has a recess in a plane parallel to the front side of the ink fountain roller, which is covered by the plate-shaped front part lying against its inside and against the ink fountain roller and that a seal arranged in the face of the main part facing the ink knife in a groove with its front end extending in the recess can be pressed against the front part by contact with the ink knife. Advantageous further developments result from the subclaims and from the description in conjunction with the drawings.

Ein Vorteil der erfindungsgemäßen Farbkastenabdichtung besteht in der einfachen Montage, da keinerlei, Paß-, Meß- oder Dichtarbeiten erforderlich sind. Desweiteren kann durch unterschiedlich angezogene Farbzonenschrauben an den Messerendbereichen das unter Umständen am Ende hoch stehende Messer nicht zu einer Spaltbildung führen, aus dem bei bekannten Vorrichtungen häufig Farbe austritt. Die erfindungsgemäße Abdichtung ist somit unempfindlich gegenüber Längenänderungen von Farbkastenwalze und Farbmesser, die häufig durch Temperaturunterschiede auftreten. Durch die vorteilhafte Verwendung und Führung der Dichtung erfolgt eine optimale seitliche Abdichtung des Farbkastens, da diese Dichtung über ihre gesamte Länge auf dem Farbmesser aufliegt und somit weder das Hauptteil noch das vordere Teil selbst das Farbmesser berührt.An advantage of the ink fountain seal according to the invention is the simple assembly, since no fitting, measuring or sealing work is required. Furthermore, due to differently tightened ink zone screws on the knife end areas, the knife, which may end up at the end, cannot lead to the formation of a gap, from which paint frequently escapes in known devices. The seal according to the invention is thus insensitive to changes in length of ink fountain roller and ink knife, which often occur due to temperature differences. The advantageous use and guidance of the seal results in an optimal lateral sealing of the ink fountain, since this seal rests on the ink knife over its entire length and therefore neither the main part nor the front part itself touches the ink knife.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels beschrieben, wobei auf die beiliegenden Zeichnungen Bezug genommen wird. In diesen zeigen :

  • Figur 1 eine Seitenwand des erfindungsgemäßen Farbkastens ;
  • Figur 2 einen Schnitt entlang der Linie II-II der Darstellung gemäß Fig. 1 ;
  • Figur 3 einen Schnitt durch die Ebene 111-111 der Darstellung gemäß Fig. und
  • Figur 4 einen Schnitt durch die Ebene IV-IV der Darstellung gemäß Fig. 1.
The invention is described below using an exemplary embodiment, reference being made to the accompanying drawings. In these show:
  • 1 shows a side wall of the ink fountain according to the invention;
  • FIG. 2 shows a section along the line II-II of the illustration according to FIG. 1;
  • 3 shows a section through the plane 111-111 of the representation according to FIGS
  • FIG. 4 shows a section through the plane IV-IV of the illustration according to FIG. 1.

Fig. 1 zeigt in der Seitenansicht einen Farbkasten mit einer Farbkastenwalze 1, die dessen vordere Begrenzung bildet. Auf einer Traverse 2 sind beidseitig Seitenwände befestigt, die senkrecht zur Achse der Farbkastenwalze 1 stehen. Jede Seitenwand besteht aus einem Hauptteil 3, der sich über die gesamte Tiefe des Farbkastens erstreckt und einem vorderen Teil 4. Der vordere Teil 4 ist im vorderen, d. h. im farbkastenwalzennahen Bereich auf der Innenseite des Hauptteils 3 parallel zu diesem angeordnet. Der Hauptteil 3 ist an der Farbkastentraverse 2 mittels Schrauben befestigbar, die in die Gewindebohrungen 5 und 6 eingedreht werden. Zur Verschraubung des vorderen Teils 4 am Hauptteil 3 dienen Zylinderschrauben 7, 8, 9 und 10. Zwischen den Seitenwänden des Farbkastens ist in herkömmlicher Weise ein Farbmesser 11 angeordnet, das in seiner Länge so bemessen ist, daß seine Seiten über die vorderen Teil 4 hinausragen (Fig. 3).Fig. 1 shows a side view of an ink fountain with an ink fountain roller 1, which forms its front boundary. On a cross member 2 side walls are attached on both sides, which are perpendicular to the axis of the ink fountain roller 1. Each side wall consists of a main part 3, which extends over the entire depth of the ink fountain and a front part 4. The front part 4 is in the front, i. H. arranged parallel to the ink fountain roller area on the inside of the main part 3. The main part 3 can be fastened to the ink fountain cross member 2 by means of screws which are screwed into the threaded bores 5 and 6. To screw the front part 4 to the main part 3 serve cylinder screws 7, 8, 9 and 10. Between the side walls of the ink fountain a color knife 11 is arranged in a conventional manner, which is dimensioned in length so that its sides protrude beyond the front part 4 (Fig. 3).

Wie Fig. erkennen läßt, ist die untere dem Farbmesser 11 zugewandte Stirnseite des Hauptteils 3 mit einer vorzugsweise schräg verlaufenden Nut 12 versehen. In dieser Nut 12 ist eine Dichtung 13 untergebracht. Diese Dichtung 13 verläuft aus dem Hauptteil 3 im farbkastennahen Bereich heraus, da der Hauptteil 3 mit einer Ausnehmung B versehen ist. Im Bereich dieser Ausnehmung B wird die Dichtung 13 von dem Dichtungsaustritt 14 ab durch ein Klemmstück 15, das in der Ausnehmung B angeordnet ist, gegen den vorderen Teil 4 gedrückt. Für diesen Zweck sind in dem äußeren Abschlußbacken in Durchgangsgewindebohrungen Schrauben 16, 17 vorgesehen, die von Hand vorzugsweise so anziehbar sind, daß ein geringer Widerstand verspürbar ist. Ein zu starkes Anziehen sollte vermieden werden, um die aus Polyamid hergestellten vorderen Teil 4 nicht zu verformen.As can be seen in FIG. 1, the lower end face of the main part 3 facing the color knife 11 is provided with a preferably inclined groove 12. A seal 13 is accommodated in this groove 12. This seal 13 runs out of the main part 3 in the region near the ink fountain, since the main part 3 is provided with a recess B. In the area of this recess B, the seal 13 is pressed from the seal outlet 14 by a clamping piece 15, which is arranged in the recess B, against the front part 4. For this purpose, screws 16, 17 are provided in the outer end jaws in through-threaded bores, which can preferably be tightened by hand so that a slight resistance can be felt. Excessive tightening should be avoided so as not to deform the front part 4 made of polyamide.

Wie Fig. 4 zeigt, ist der Hauptteil 3 von der Stirnseite C der Farbkastenwalze 1 etwa 1,5 mm beabstandet, während der vordere Teil 4 auf dem Mantel der Farbkastenwalze 1 aufsitzt.As shown in FIG. 4, the main part 3 is about 1.5 mm from the front side C of the ink fountain roller 1 spaced while the front part 4 sits on the jacket of the ink fountain roller 1.

Durch die in der Nut 12 angeordnete auf dem Farbmesser 11 aufsitzende Dichtung ist eine exakte seitliche Abdichtung der Teile 3 und 4 möglich. Desweiteren wird durch die Verwendung einer Druckplatte 18, die senkrecht zur Stirnseite C der Farbkastenwalze 1 an der dieser zugekehrten Vorderseite des Hauptteils 3 mittels Schrauben 19, 20 anschraubbar ist, die Dichtung 13 in diesem kritischen Bereich gestaucht, wodurch der Dichtungseffekt zusätzlich verbessert wird.An exact lateral sealing of the parts 3 and 4 is possible due to the seal arranged in the groove 12 on the ink knife 11. Furthermore, by using a pressure plate 18, which can be screwed perpendicularly to the end face C of the ink fountain roller 1 on the front side of the main part 3 facing it by means of screws 19, 20, the seal 13 is compressed in this critical area, which additionally improves the sealing effect.

Die Dichtung 13 ist in ihrer Höhe so bemessen, daß sie durch das Anschrauben des Hauptteils 3 mittels der Schraube 21 über ihre gesamte Länge zusammengepreßt wird und dadurch die seitliche Abdichtung gewährleistet.The height of the seal 13 is such that it is compressed over its entire length by screwing on the main part 3 by means of the screw 21, thereby ensuring the lateral seal.

Wie Fig. 1 am besten zeigt, ist der untere in dem Dreieck zwischen Farbkastenwalze 1 und Farbmesser 11 liegende Bereich des vorderen Teils 4 etwa keilförmig ausgebildet, wobei sein Winkel etwas kleiner als der Farbmesserwinkel ist (Pfeil A). Bei der Montage wird der vordere Teil 4 an den Mantel der Farbkastenwalze 1 gedrückt und nach unten gedreht, bis die Keilspitze das Farbmesser 11 berührt. In diesem Zustand wird der vordere Teil4 an den Hauptteil3 angeschraubt. Da die im Hauptteil 3 eingelegte Dichtung 13 im nahen Farbkastenwalzenbereich freiliegt und gegen den vorderen Teil 4 abdichtet, wird auch der Spalt verschlossen, der durch die unterschiedlichen Winkel entsteht (Keilform des vorderen Teils 4 und des Messerwinkels), was einen weiteren Vorteil bedeutet. Die Berührungsfläche des vorderen Teils4 an der Farbkastenwalze ist vorzugsweise schmal gehalten, um stauungen verdickter Farbe zu vermeiden und um nicht zu sehr von der exakten Winkligkeit der Abschlußteile abhängig zu sein. Im Einlaufbereich des vorderen Teils4 ist die Berührungsfläche stark abgeschrägt, um eine gute Ableitung des von der Farbkastenwalze 1 mitgenommenen Farbfilms zu ermöglichen. Bei dem erfindungsgemäßen Farbkasten ist eine exakte Abdichtung unabhängig von Längenänderungen des Farbmessers 11 und der Farbkastenwalze 1 gewährleistet. Um zu vermeiden, daß sich das Farbmessern infolge der auf dieses senkrecht drückenden Dichtungskraft nicht verbiegt, kann das Farbmesser 11 durch Stützelemente, vorzugsweise in Form von Schrauben abgestützt werden.As best shown in FIG. 1, the lower region of the front part 4, which lies in the triangle between ink fountain roller 1 and ink knife 11, is approximately wedge-shaped, its angle being somewhat smaller than the ink knife angle (arrow A). During assembly, the front part 4 is pressed against the jacket of the ink fountain roller 1 and rotated downward until the wedge tip touches the ink knife 11. In this state, the front part 4 is screwed onto the main part 3. Since the seal 13 inserted in the main part 3 is exposed in the vicinity of the ink fountain roller area and seals against the front part 4, the gap caused by the different angles is also closed (wedge shape of the front part 4 and the knife angle), which means a further advantage. The contact surface of the front part 4 on the ink fountain roller is preferably kept narrow in order to avoid congestion of thickened paint and not to be too dependent on the exact angularity of the end parts. In the inlet area of the front part 4, the contact surface is sharply chamfered in order to allow good removal of the ink film carried along by the ink fountain roller 1. In the ink fountain according to the invention, an exact seal is guaranteed regardless of changes in length of the ink knife 11 and the ink fountain roller 1. In order to avoid that the ink knife does not bend as a result of the sealing force pressing vertically on it, the ink knife 11 can be supported by support elements, preferably in the form of screws.
