Hierzu kann der Farbkasten mit entsprechenden Lagerböcken 25 versehen sein. Auf diese Weise ergibt ein durch die Multifunktionsschiene 11 mit Verbreiterungsansatz 24 gebildeter Schwenkdeckel, der in der normalen, der Figur 1 zugrundeliegenden Betriebsstellung den Farbkasten 1 nach oben verschließt und der zur Bewerkstelligung einer guten Zugänglichkeit zum Innenraum des Farbkastens 1 und zum Duktor 2 hochschwenkbar ist, wie in Figur 4 bei 26 angedeutet ist. Anstelle einer Abschwenkbarkeit könnte auch eine Verschiebbarkeit etc. vorgesehen sein.The multifunction rail 11 is in the example shown, as in FIGS. 1 and 4 can be removed, provided with a widening extension 24, so that overall gives a width covering the ink fountain 1. The Widening approach 24 can be integrally formed. In the example shown is Widening approach 24 as attachable to the multi-function rail 11 Widening bar formed. The hollow chamber profile 15 and the cover 13, 14 are accordingly provided with suitable connection surfaces. The Multifunction rail 11 is suitably pivoted. For this, the Color box with corresponding bearing blocks 25 may be provided. In this way results in a formed by the multifunction rail 11 with a widening approach 24 Swing cover, in the normal operating position on which FIG. 1 is based closes the ink fountain 1 upwards and the one to accomplish a good one Accessibility to the interior of the ink fountain 1 and to the ductor 2 is pivoted up, as indicated in Figure 4 at 26. Instead of one Swiveling could also be provided, etc.

Die Multifunktionsschiene 11 ist so oberhalb des Farbkastens 1 plaziert, dass sie sich mit ihrem die Auslassöffnungen 4 enthaltenden Bereich oberhalb des Duktors 2 befindet. Die aus den Auslassöffnungen 4 austretende Farbe wird daher durch den rotierenden Duktor 2 in den Spalt zwischen Duktoroberfläche und Farbkastenboden hineintransportiert. Der im Einschubkanal 16 aufgenommene Füllstandssensor 9 befindet sich dabei sehr nahe beim Duktor 2 und dementsprechend oberhalb des untersten Bereichs des Farbkastens 1, so dass die Sensorstrahlen 27 auch noch einen sehr niedrigen Füllstand erfassen. Hierdurch ist sichergestellt, dass mit einem vergleichsweise geringen Farbvorrat 3 gearbeitet werden kann. Auf diese Weise lässt sich der im Falle eines Farbwechsels nicht vermeidbare Farbverlust sehr klein halten.The multi-function rail 11 is placed above the ink fountain 1 so that it is with its area containing the outlet openings 4 above the ductor 2 located. The color emerging from the outlet openings 4 is therefore by the rotating duct 2 in the gap between the duct surface and the ink fountain floor into transports. The fill level sensor 9 received in the insertion channel 16 is very close to Duktor 2 and accordingly above the lowest area of the ink fountain 1, so that the sensor beams 27 also detect a very low level. This ensures that with a comparatively low color stock 3 can be worked. In this way the loss of color that is unavoidable in the event of a color change can be very small hold.

Im Falle eines ungeteilten Farbkastens erstreckt sich die Multifunktionsschiene 11, wie oben schon angedeutet wurde, über die ganze Farbkastenlänge. Im Falle eines unterteilten Farbkastens sind, wie aus Figur 5 erkennbar ist, mehrere nebeneinander angeordnete Multifunktionsschienen 11 vorgesehen, die sich jeweils über das zugeordnete Abteil erstrecken. Bei dem der Figur 5 zugrundeliegenden Beispiel sind vier Multifunktionsschienen 11 vorgesehen, die paarweise symmetrisch zur Mittellängsebene angeordnet sind und zwar so, dass ihre in die Farbzuführleitung einbezogenen Deckel 14 der jeweils benachbarten Maschinenseitenwand 27 zugewandt sind. Die Maschinenseitenwände 27 sind mit Durchbrechungen 28 versehen, durch welche die zu den Deckeln 14 führenden Schläuche 6a der Farbzuführleitung durchführbar sind. In jeder Maschinenseitenwand 27 ist eine Farbleitung 29 verlegt, an welche die Schläuche 6a anschließbar sind und die in an sich bekannter Weise mit Hauptabsperreinrichtungen versehen ist. In the case of an undivided ink fountain, the multifunction rail 11 extends as already indicated above, over the entire length of the ink fountain. in case of a divided color box are, as can be seen from Figure 5, several side by side arranged multi-function rails 11 are provided, each of which extend assigned compartment. In the example on which FIG. 5 is based Four multifunction rails 11 are provided, which are symmetrical in pairs Are arranged in the central longitudinal plane and in such a way that their in the paint supply line included cover 14 of the respective adjacent machine side wall 27 are facing. The machine side walls 27 have openings 28 provided through which the leading to the covers 14 hoses 6a Ink supply line can be carried out. There is one in each machine side wall 27 Color line 29 laid, to which the hoses 6a can be connected and which in is known to be provided with main shut-off devices.

Im dargestellten, besonders bevorzugten Ausführungsbeispiel enthält jede Multifuktionsschiene 11 eine dezentrale Steuereinrichtung 10. Alternativ wäre es natürlich auch denkbar, die Signale der Füllstandssensoren 9 über eine Datenleitung zu einer zentralen Steuereinrichtung, beispielsweise zum Hauptrechner der Druckmaschine zu führen und die Betätigungseinrichtungen 8 durch die zentrale Steuereinrichtung anzusteuern. Ebenso wäre es denkbar, mehrere, verschiedenen Farben zuordenbare Versorgungskanäle vorzusehen, die von einem gemeinsamen, mehrere Ventilanordnungen enthaltenden Deckel oder von einander gegenüberliegenden Decklen aus versorgbar sind.In the particularly preferred embodiment shown, each contains Multifunction rail 11 a decentralized control device 10. Alternatively, it would be naturally also conceivable, the signals of the level sensors 9 via a data line to a central control device, for example to the main computer of the To guide printing machine and the actuators 8 through the central Control device. It would also be conceivable to have several different ones Provide color-assignable supply channels that are shared by a common multiple valve assemblies containing lids or from each other opposite lids are available from.
