Abstract

The ink duct element for a rotary printing machine has a handle (10) on a first longitudinal side (4) of the element (1), a slide (6) on its opposite longitudinal side (5) facing the ductor (15), and an elbow (11) arranged between the handle and the first longitudinal side for hooking the element onto the outside edge (12) of the ink duct (13) of the rotary printing machine. Such an element allows a rapid colour change without the necessity of either cleaning the printing machine or removing parts. Additionally, the element can be used on the machine or its ink duct without change. <IMAGE>

Description

Bei Rotationsdruckmaschinen mit Mehrfarbendruck werden die verschiedenen Farben über Farbkästen auf den Duktor gegeben (siehe z.B. US-A-512 562), wobei in der Regel der der Farbwechselvorgang sehr zeitaufwendig und mühsam ist und erfordert, dass die Farbkästen entweder an der Maschine gereinigt werden oder ausgewechselt werden. Die Wechsel- bzw. Reinigungsverfahren sind nicht nur zeitaufwendig sondern bringen auch die Gefahr mit sich, dass Teile der Rotationsdruckmaschine verschmutzt werden.In rotary printing presses with multi-color printing, the different colors are applied to the ductor via ink fountains (see, for example, US-A-512 562), although the color change process is usually very time-consuming and tedious and requires that the ink fountains are either cleaned on the machine or be replaced. The changing or cleaning processes are not only time-consuming, but also entail the risk that parts of the rotary printing press are contaminated.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung eine Vorrichtung anzugeben, die es erlaubt, rasch und bequem die verschiedenen Farben an den Duktor zu bringen und die es weitgehendst vermeidet, die durch den Farbwechsel bedingte Reinigung der Rotationsdruckmaschine durchführen zu müssen. Die Vorrichtung die diese Aufgabe löst, ist in den Patentansprüchen definiert.It is based on the object of the present invention to provide a device which allows the various colors to be brought to the ductor quickly and conveniently and which largely avoids having to carry out the cleaning of the rotary printing press due to the color change. The device that solves this problem is defined in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.

zeigt in perspektivischer Draufsicht ein erstes Ausführungsbeispiel eines erfindungsgemässen Farbkasten-Einsatzes,
Fig. 2
zeigt den eingehängten Farbkasten-Einsatz gemäss Fig. 1 im Schnitt,
Fig. 3

The invention is explained in more detail below with reference to a drawing of exemplary embodiments.
Fig. 1
shows a perspective top view of a first embodiment of an ink fountain insert according to the invention,
Fig. 2
shows the suspended ink fountain insert according to FIG. 1 in section,
Fig. 3
shows an embodiment of the ink fountain of Fig. 1, and
Fig. 4
shows, partly in section, a second embodiment of an ink fountain insert according to the invention.

Der Einsatz 1 weist einen rechteckigen Grundriss auf, wobei Boden 2 und damit die beiden Querseiten 3, ungefähr diagonal verlaufen, um dem Farbkasten-Einsatz ein trichterförmiges Aussehen zu geben. Dabei verläuft der Boden 3 logischerweise von der griffseitigen Längsseite 4 oben zu der anderen Längsseite 5 unten, an welcher ein Schieber 6 angeordnet ist. Der Schieber 6 ist in Nuten 7 in den Querseiten 3 geführt und entweder so angepasst, dass er selbsthemmend ist oder mittels Federn 8 gebremst wird. Zwecks besserer Handhabung weist der Schieber eine Grifföffnung 9 auf.The insert 1 has a rectangular outline, the bottom 2 and thus the two transverse sides 3 being approximately diagonal in order to give the ink fountain insert a funnel-shaped appearance. The floor 3 logically runs from the handle-side long side 4 above to the other long side 5 below, on which a slide 6 is arranged. The slider 6 is guided in grooves 7 in the transverse sides 3 and either adapted so that it is self-locking or is braked by means of springs 8. For better handling, the slide has a handle opening 9.

An der anderen Längsseite 4 ist, ungefähr parallel zum Schieber, ein Griff 10 angeordnet, der über ein Winkelstück 11 mit der Längsseite 4 verbunden ist. Die Unterseite des Winkelstücks hat gemäss Fig. 2 die Aufgabe, den Rand 12 des Farbkastens 13 zu umfassen, um den Einsatz im Farbkasten zu halten. In Fig. 2 erkennt man ferner das Farbmesser 14 und den Duktor 15.On the other long side 4, a handle 10 is arranged approximately parallel to the slide, which is connected to the long side 4 via an angle piece 11. 2, the underside of the angle piece has the task of enclosing the edge 12 of the ink fountain 13 in order to keep the insert in the ink fountain. The color meter 14 and the ductor 15 can also be seen in FIG. 2.

Aus der Beschreibung geht hervor, dass der Farbkasten-Einsatz gedacht ist, in bestehende Farbkästen eingehängt zu werden, so dass an den Druckmaschinen keinerlei Veränderungen vorgenommen werden müssen. Die einzelnen Farbkästen sind an den Griffen leicht transportierbar und können auf dazu geeigneten Transporteinrichtungen angeordnet werden.The description shows that the ink fountain insert is intended to be attached to existing ink fountains, so that no changes need to be made to the printing press. The individual paint boxes can be easily transported on the handles and can be arranged on suitable transport devices.

In Fig. 3 ist in Seitenansicht eine Ausführungsvariante dargestellt, in welcher ein Deckel 16 an einem Scharnier 17 angelenkt ist, derart, dass der Deckel einerseits den Farbkasten-Einsatz abschliesst und andererseits in der strichpunktiert dargestellten Stellung verhindert, dass Farbe aus dem Einsatz in Teile der Druckmaschine gelangen kann.3 shows a side view of an embodiment variant in which a cover 16 is articulated on a hinge 17 such that the cover on the one hand closes the ink fountain insert and on the other hand in the position shown in broken lines prevents paint from being used in parts the printing press can get.

In Figur 4 ist ein zweites, bevorzugtes Ausführungsbeispiel eines Farbkasten-Einsatzes dargestellt, mit dem noch weniger Farbverluste auftreten können und der dadurch ein noch schnelleres Umrüsten ermöglicht als das erste Ausführungsbeispiel.FIG. 4 shows a second, preferred exemplary embodiment of an ink fountain insert, with which even less color losses can occur and which therefore enables an even faster changeover than the first exemplary embodiment.

Auch der Einsatz 21 gemäss Figur 4 weist einen rechteckigen Grundriss auf, und der Boden 22 sowie die entsprechenden Kanten der beiden Querseiten 23 verlaufen ungefähr diagonal zur Vorderseite 25, an der der Schieber 26 angeordnet ist. Der Schieber läuft in Nuten 27 in den Querseiten und ist entweder wie gezeichnet selbsthemmend konstruiert oder er kann mittels Federn gebremst werden. Zur besseren Handhabung weist der Schieber zwei Oeffnungen 28 auf. Im Unterschied zu der Ausführungsform gemäss Figur 2 ist vor dem Schieber - vom Duktor 15 aus gesehen - eine Vorderwand 43 in den Seitenwänden eingelassen, die bis fast ganz nach unten reicht und einen schmalen Schlitz 44 offen lässt, um die Farbmenge bei offenem Schieber zu verringern. Aus Figur 4 ist ersichtlich, dass die Vorderwand unten die gleiche Krümmung wie die Seitenwände aufweist.The insert 21 according to FIG. 4 also has a rectangular outline, and the base 22 and the corresponding edges of the two transverse sides 23 run approximately diagonally to the front side 25 on which the slide 26 is arranged. The slide runs in grooves 27 in the transverse sides and is either designed as self-locking as shown or it can be braked by means of springs. For better handling, the slide has two openings 28. In contrast to the embodiment according to FIG. 2, a front wall 43 is embedded in the side walls in front of the slide, as seen from the duct 15, which extends almost all the way down and leaves a narrow slot 44 open in order to reduce the amount of paint when the slide is open . It can be seen from FIG. 4 that the front wall has the same curvature as the side walls.

An der anderen Längsseite 24 ist über ein Winkelstück 29 ein Griff 30 angeordnet, wobei das Winkelstück den Rand 31 des Farbkastens 32 umfasst. Das Farbmesser 34 ist mit einem Befestigungsteil 38 am Farbkasten 32 befestigt und wird durch einen Stössel 33 an den Duktor 15 gepresst, wobei der Stössel durch eine Stellschraube 35 eingestellt wird. Ferner weist der Farbkasten 32 einen Griff 36 auf, an dem dieser mitsamt dem Stössel und Einstelleinrichtung um eine Achse 37 nach unten geschwenkt werden kann.A handle 30 is arranged on the other long side 24 via an angle piece 29, the angle piece comprising the edge 31 of the ink fountain 32. The ink knife 34 is fastened to the ink fountain 32 with a fastening part 38 and is pressed against the duct 15 by a plunger 33, the plunger being set by an adjusting screw 35. In addition, the ink fountain 32 has a handle 36, on which it can be pivoted downward about an axis 37 together with the plunger and adjusting device.

Ein Vergleich der Figuren 2 und 4 zeigt, dass ein wesentlicher Unterschied zwischen den beiden Ausführungsbeispielen darin besteht, dass der Boden 22 und die entsprechenden Kanten der Querseiten 23 sowie die Vorderseite 25 zum Duktor hin verlängert sind derart, dass ein sehr kleiner Abstand zwischen dem Duktor und der Vorderseite, bzw. Vorderkante 39 des Bodens entsteht und sich dadurch sehr wenig Farbe in diesem Bereich ansammeln kann. Ausserdem können beim Abnehmen des Einsatzes eventuell verbliebene Farbreste durch diese Vorderkante 39 abgestreift werden.A comparison of Figures 2 and 4 shows that a significant difference between the two embodiments is that the bottom 22 and the corresponding Edges of the transverse sides 23 and the front side 25 are extended towards the ductor in such a way that there is a very small distance between the ductor and the front or front edge 39 of the base and very little color can accumulate in this area. In addition, any remaining paint residues can be wiped off through this front edge 39 when the insert is removed.

Ein weiterer Unterschied zum ersten Ausführungsbeispiel ergibt aus dem Absatz 40 am Knick im Boden resp. in den Seitenwänden, dem ein Absatz 41 in den Seitenwänden 42 des Farbkastens 32 entspricht. Diese Absätze wirken zusammen mit dem Winkelstück 29 am Griff, um eine definierte Lage des Einsatzes gegenüber dem Farbkasten und Farbmesser zu erreichen.Another difference to the first embodiment results from paragraph 40 at the kink in the floor, respectively. in the side walls, which corresponds to a shoulder 41 in the side walls 42 of the ink fountain 32. These paragraphs work together with the angle piece 29 on the handle in order to achieve a defined position of the insert in relation to the ink fountain and ink knife.

Auch dieser Farbkasten weist einen mit Scharnieren angelenkten Deckel 16 auf.This ink fountain also has a hinged lid 16.
