Abstract

In an ink baffle in an ink reservoir of a rotary printing machine, a profile body is arranged within an ink distribution channel to prevent turbulence within the ink. To alter the ink pressure between the profile body and the screen roller, the profile body is arranged to be able to pivot or to rotate, depending on its design.

Description

Die Erfindung betrifft eine Farbauftragsleiste für ein Spülfarbwerk einer Rotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an ink application bar for a rinse inking unit of a rotary printing press according to the preamble of claim 1.

Die DE-OS 31 35 711 zeigt ein Spülfarbwerk für eine Rotationsdruckmaschine. Das Spülfarbwerk besteht aus einer Farbauftragsleiste und zwei davon ober- und unterschlächtig angeordneten Rakelmessern, die zusammen mit einer Rasterwalze eine Farbverteilungsrinne bilden. Der Querschnitt dieser Farbverteilungsrinne ist rechteckförmig und weist im Bereich der Rakelmesser jeweils eine zusätzliche Kante auf. Diese Ecken und Kanten führen zum Aufbau von Turbulenzen und Vibrationen innerhalb der Farbe. Hierbei kommt es insbesondere bei hohen Umfangsgeschwindigkeiten der Rasterwalze zu Blasenbildung und damit zu ungleichmäßigem Einfärben der Rasterwalze, bzw. schlechter Füllung der Näpfchen.DE-OS 31 35 711 shows a flushing inking unit for a rotary printing press. The flushing inking unit consists of an ink application bar and two doctor blades arranged above and below it, which together with an anilox roller form an ink distribution channel. The cross section of this ink distribution channel is rectangular and each has an additional edge in the area of the doctor blade. These corners and edges lead to the build-up of turbulence and vibrations within the color. Here, especially at high peripheral speeds of the anilox roller, blistering occurs and thus uneven inking of the anilox roller or poor filling of the cells.

Die US-PS 41 58 333 zeigt ein Spülfarbwerk, das ebenfalls an eine Näpfchen aufweisende Rasterwalze angestellt ist. Das Spülfarbwerk weist ein unterschlächtig angeordnetes Rakelmesser und eine Anzahl senkrechter Wände auf, die mit Durchbrüchen versehen sind.The US-PS 41 58 333 shows a flushing inking unit, which is also employed on an anilox roller having cups. The flushing inking unit has a doctor blade arranged underneath and a number of vertical walls which are provided with openings.

Nachteilig an der durch die US-PS 41 58 333 gezeigten Vorrichtung ist die Eignung des Spülfarbwerkes für nur eine Drehrichtung der Rasterwalze. Außerdem vermag die Farbführung durch stationäre Wände und Durchbrüche nichts zur Druckänderung der Farbe auf die Rasterwalze beizutragen. Hierzu kommt ein außerordentlich großer Platzbedarf des Spülfarbwerkes, der ein vielfaches größer ist, als bei einer herkömmlichen Farbauftragsleiste.A disadvantage of the one shown by the US-PS 41 58 333 The device is the suitability of the flushing inking unit for only one direction of rotation of the anilox roller. In addition, the ink flow through stationary walls and openings does nothing to change the pressure of the ink on the anilox roller. In addition, there is an extraordinarily large space requirement for the flushing inking unit, which is many times larger than in the case of a conventional ink application bar.

Der Erfindung liegt die Aufgabe zugrunde, eine Farbauftragsleiste für ein Spülfarbwerk einer Rotationsdruckmaschine zu schaffen, das die Strömung der Farbe in der Farbkammer begünstigt.The invention has for its object to provide an ink application bar for a rinse inking unit of a rotary printing press, which favors the flow of ink in the ink chamber.

Die Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Anspruches 1 gelöst.The object is achieved by the characterizing part of claim 1.

Die Vorteile der Erfindung liegen insbesondere darin, daß durch den Aufbau einer gleichmäßigen Farbströmung ohne Turbulenzen ein gleichmäßiger Farbkontakt mit der Farbauftragswalze auch bei hohen Umfangsgeschwindigkeiten möglich ist und ein Farbflüssigkeitsdruck zur besseren Füllung der Näpfchen der Farbauftragswalze regelbar ist.The advantages of the invention are, in particular, that by building up a uniform ink flow without turbulence, even ink contact with the inking roller is possible even at high peripheral speeds, and ink liquid pressure can be regulated to better fill the cells of the inking roller.

Zwei Auführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Farbauftragsleiste im Schnitt mit erfindungsgemäßem Farbkammerprofil,
  • Fig. 2 eine Seitenansicht der Farbauftragsleiste mit Profilkörper-Verstellvorrichtung,
  • Fig. 3 einen Schnitt III - III in Fig. 2,
  • Fig. 4 eine zweite Ausführungsform mit rotierbarem Profilkörper,
  • Fig. 5 einen Profilkörperquerschnitt,
  • Fig. 6 einen Profilkörperquerschnitt,
  • Fig. 7 einen Profilkörperquerschnitt.
Two exemplary embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • 1 is a paint application bar in section with an ink chamber profile according to the invention,
  • 2 is a side view of the paint application bar with profile body adjustment device,
  • 3 shows a section III - III in FIG. 2,
  • 4 shows a second embodiment with a rotatable profile body,
  • 5 shows a profile body cross section,
  • 6 a profile body cross section,
  • Fig. 7 shows a profile cross section.

Eine als Rasterwalze 1 ausgebildete Einfärbwalze ist in Farbwerksböcken (nicht dargestellt) drehbar gelagert. Die Rasterwalze 1 bildet mit einer parallel zu ihrer Drehachse angeordneten Farbauftragsleiste 2, einem oberen Rakelmesser 3 und einem unteren Abstreifmesser 4 eine walzenlange Farbverteilungskammer 6. Die Farbverteilungskammer 6 weist glatte, gerundete Innenwände 7 auf. In der Mitte der Farbverteilungskammer 6 ist eine Bohrung 9 für die Farbzufuhr vorgesehen, die an eine nicht dargestellte Farbzuführvorrichtung anschließbar ist. Das Farbmesser 3 ist von außen an eine obere Schräge 11, das Abstreifmesser 4 von außen an eine untere Schräge 12 der Farbauftragsleiste 2 angeschraubt. Die Farbverteilungskammer 6 ist an ihren Stirnseiten mittels Seitenblechen 14, 15 abgedeckt, die z. T. die Stirnflächen 8, 13 der Rasterwalze 1 überragen. In der Farbverteilungskammer 6 ist ein Profilkörper 16 mittels, an seinen Stirnseiten 17, 18 angebrachten, Wellenzapfen 19, 21 frei umströmbar in Seitenschildern 23, 28 schwenkbar gelagert. Die Seitenschilder 23, 28 sind jeweils seitlich an die Farbauftragsleiste 2 angeschraubt, so daß die Seitenbleche 14, 15 jeweils zwischen der Farbauftragsleiste 2 und den Seitenschildern 23; 28 angeordnet sind.A inking roller designed as anilox roller 1 is rotatably mounted in inking units (not shown). The anilox roller 1 forms, with an ink application bar 2 arranged parallel to its axis of rotation, an upper doctor blade 3 and a lower doctor blade 4, a roller-long ink distribution chamber 6. The ink distribution chamber 6 has smooth, rounded inner walls 7. In the middle of the ink distribution chamber 6 there is a hole 9 for the ink supply, which can be connected to an ink supply device, not shown. The paint knife 3 is screwed from the outside to an upper slope 11, the doctor blade 4 from the outside to a lower slope 12 of the paint application bar 2. The color distribution chamber 6 is covered on its end faces by means of side plates 14, 15 which, for. T. protrude the end faces 8, 13 of the anilox roller 1. In the color distribution chamber 6, a profile body 16 is pivotally mounted in side plates 23, 28 by means of shaft journals 19, 21 attached to its end faces 17, 18. The side plates 23, 28 are each screwed to the side of the paint application bar 2, so that the side plates 14, 15 each between the paint application bar 2 and the side plates 23; 28 are arranged.

Der Profilkörper 16 ist in Achsrichtung gesehen nahezu genauso lang wie eine Breite b der Rasterwalze 1. Der Profilkörper 16 ist im Querschnitt ellipsenförmig.Viewed in the axial direction, the profile body 16 is almost as long as a width b of the anilox roller 1. The profile body 16 is elliptical in cross section.

Ein Verschwenken des Profilkörpers 16 um seine Drehachse 22 hat somit eine Änderung einer kleinsten Spaltweite SO zur Folge. Der Spalt S wird von der Rasterwalze 1 und der der Rasterwalze 1 zugewandten Mantelfläche 24 des Profilkörpers 16 gebildet. Eine Kraft F der Farbe im Spalt S ist, in Drehrichtung der Rasterwalze 1 gesehen, kurz vor der kleinsten Spaltweite SO am größten. Die Tragfähigkeit f/b der Druckfarbe und damit die Kraft der Farbe auf die Näpfchen 28 der Rasterwalze 1 kann nach folgender Formel berechnet werden:

Figure imgb0001
(siehe auch VDI-Forschungsheft 391, Seite 82 - 85)A pivoting of the profile body 16 about its axis of rotation 22 thus results in a change in the smallest gap width S O. The gap S is formed by the anilox roller 1 and the lateral surface 24 of the profile body 16 facing the anilox roller 1. A force F of the ink in the gap S is greatest just before the smallest gap width S O , as seen in the direction of rotation of the anilox roller 1. The load capacity f / b of the printing ink and thus the force of the ink on the cups 28 of the anilox roller 1 can be calculated using the following formula:
Figure imgb0001
 (see also VDI research booklet 391, pages 82 - 85)

Hierbei ist η = Zähigkeit der Farbe, r₁= Radius der Rasterwalze 1, r₂ = Radius der, der Rasterwalze 1 zugewandten, Mantelfläche 24, v₁ = Umfangsgeschwindigkeit der Rasterwalze 1, V₂ = Umfangsgeschwindigkeit des Profilkörpers (z.B. = 0), da der Profilkörper 16 stationär angeordnet ist und b = Länge des Profilkörpers 16. Eine Veränderung der kleinsten Spaltweite So hat somit eine unmittelbare Kraftänderung der Farbe auf die Rasterwalze 1 zur Folge.Here, η = toughness of the color, r₁ = radius of the anilox roller 1, r₂ = radius of the outer surface 24 facing the anilox roller 1, v₁ = peripheral speed of the anilox roller 1, V₂ = peripheral speed of the profile body (e.g. = 0), since the profile body 16th is stationary and b = length of the profile body 16. A change in the smallest gap width S o thus has an immediate change in the force of the color on the Anilox roller 1 result.

Eine Verschwenkung des Profilkörpers 16 erfolgt durch jeweils außen an den Seitenschildern 23, 28 angebrachten Stellvorrichtungen 31, 32. Die Stellvorrichtungen 31, 32 bestehen jeweils aus einer Stellspindel 33, 34, die durch ein Gewindedurchgangsloch 38; 39 einer am Seitenschild 23; 28 befestigten Halterung 36; 37 hindurchgeschraubt ist. Jeweils an ihrem Ende 41; 42 weist die Stellspindel 33; 34 eine Kugel 43; 44 auf, die in eine senkrechte Führungsnut 46; 47 eines Hebels 48; 49 eingreift. Der Hebel 48; 49 ist auf dem durch das Seitenblech 14; 15 und das Seitenschild 23; 28 hindurchragenden Wellenzapfen 19; 21 drehfest angeordnet. Die Stellspindel 33; 34 weist zu ihrer Betätigung einen Stellkopf 51; 52 auf, der z. B. gerändelt sein kann, damit er von Hand leicht zu bedienen ist. Selbstverständlich ist es auch möglich dort zum Zwecke einer möglichen Fernverstellung einen Stellmotor anzuordnen.The profile body 16 is pivoted by adjusting devices 31, 32 attached to the outside of the side plates 23, 28 in each case. The adjusting devices 31, 32 each consist of an adjusting spindle 33, 34 which is passed through a threaded through hole 38; 39 one on the side plate 23; 28 attached bracket 36; 37 is screwed through. At each end 41; 42 has the adjusting spindle 33; 34 a ball 43; 44, which in a vertical guide groove 46; 47 a lever 48; 49 engages. The lever 48; 49 is on the through the side plate 14; 15 and the side plate 23; 28 protruding shaft journal 19; 21 rotatably arranged. The adjusting spindle 33; 34 has an adjusting head 51; 52 on the z. B. can be knurled so that it is easy to use by hand. Of course, it is also possible to arrange a servomotor there for the purpose of remote adjustment.

Der Profilkörper 16 ist mittels der Stellvorrichtungen 31, 32 aus einer, in Fig. 2 gestrichelt dargestellten Mittelstellung, je nach Drehrichtung der Rasterwalze 1 und erforderlicher Kraft F der Farbe auf die Rasterwalze 1 um einen Winkel φ z. B. ± 20° ausschwenkbar. Hierzu zeigt Fig. 1 mit durchgezogenener Linie eine Schwenkstellung des Profilkörpers 16 für eine Rasterwalzendrehrichtung im Uhrzeigersinn. Die strichpunktierte Linie kennzeichnet eine mögliche Stellung des Profilkörpers 16 für eine Drehrichtung der Rasterwalze 1 entgegen dem Uhrzeigersinn.The profile body 16 is by means of the adjusting devices 31, 32 from a central position shown in dashed lines in FIG. 2, depending on the direction of rotation of the anilox roller 1 and the required force F of the ink on the anilox roller 1 by an angle φ z. B. can be swung out ± 20 °. For this purpose, FIG. 1 shows with a solid line a pivoting position of the profile body 16 for an anilox roller rotation direction in the clockwise direction. The dash-dotted line indicates a possible position of the profile body 16 for a direction of rotation of the anilox roller 1 counterclockwise.

Der Erfindungsgedanke soll sich nicht allein auf das gezeigte Ausführungsbeispiel beschränken, so ist es auch möglich, andere Profilkörper (53, 54, 55) vorzusehen. Hierzu zeigt Fig. 5 einen Querschnitt des Profilkörpers 53 der auf einer der Rasterwalze 1 zugewandten Seite eine konvexe Form und auf einer Farbrückstromseite eine konkave Form aufweist. Die Enden des Profilkörpers 53 sind abgerundet, wobei eine Rundung einen größeren Radius aufweist als die andere (Flügelprofil).The idea of the invention should not be limited to the exemplary embodiment shown, it is also possible to provide other profile bodies (53, 54, 55). 5 shows a cross section of the profile body 53 which has a convex shape on a side facing the anilox roller 1 and a concave shape on a color backflow side. The ends of the profile body 53 are rounded, one rounding having a larger radius than the other (wing profile).

Der Profilkörper 54 in Fig. 6 entspricht im wesentlichen dem Profilkörper 53, jedoch mit gleichen Endradien.The profile body 54 in FIG. 6 essentially corresponds to the profile body 53, but with the same end radii.

Der Profilkörper 56 in Fig. 7 weist zwei konkav ausgeführte Mantelflächen auf.The profile body 56 in FIG. 7 has two concave outer surfaces.

Bei einem zweiten Ausführungsbeispiel (Fig. 4) ist innerhalb einer kreisförmig ausgeführten Farbverteilungskammer 58 ein zylindrischer Profilkörper 57 angeordnet. Der Profilkörper 57 ist in den Seitenschildern 23, 28 drehbar gelagert und ist an die Rasterwalze 1 angestellt. Der Profilkörper 57 wird durch Reibung von der Rasterwalze 1 angetrieben. Selbstverständlich ist es auch möglich den Profilkörper 57 mit Hilfsmitteln anzutreiben. Es ist auch möglich, Mittel (z.B. Lagerung des Profilkörpers 57 in Exzenterbuchsen) zum Ändern des Achsabstandes von Profilkörper 57 und Rasterwalze 1 vorzusehen, wodurch ein größerer Schlupf zwischen Rasterwalze 1 und Profilkörper 57 entsteht. Dies führt zu einer Verminderung der Umfangsgeschwindigkeit (V₂) des Profilkörpers 57 und gleichzeitig zu einer Erweiterung der kleinsten Spaltbreite S₀, so daß der Druck der Farbe auf die Rasterwalze 1 sinkt. Zur Reduzierung jeglicher Strömungsstörungen oder Verwirbelungen der Druckfarbe ist es von Vorteil, wenn die Oberflächen der Profilkörper 16, 53, 56, 57 glatt sind.In a second exemplary embodiment (FIG. 4), a cylindrical profile body 57 is arranged within a circular color distribution chamber 58. The profile body 57 is rotatably mounted in the side plates 23, 28 and is set against the anilox roller 1. The profile body 57 is driven by the anilox roller 1 by friction. Of course, it is also possible to drive the profile body 57 with aids. It is also possible to provide means (for example, mounting the profile body 57 in eccentric bushes) for changing the center distance of the profile body 57 and anilox roller 1, as a result of which there is greater slippage between the anilox roller 1 and the profile body 57. This leads to a reduction in the peripheral speed (V₂) of the profile body 57 and at the same time to an expansion the smallest gap width S₀, so that the pressure of the ink on the anilox roller 1 drops. To reduce any flow disturbances or turbulence in the printing ink, it is advantageous if the surfaces of the profile bodies 16, 53, 56, 57 are smooth.
