Abstract
Description
Die Erfindung betrifft ein Verfahren zum Zuführen von Druckfarbe in Farbkästen von Druckmaschinen, bei dem der Farbbedarf der Farbzonen ermittelt, diese Werte einem Rechner zugeführt werden, dort verarbeitet werden und Steuerbefehle zur zonalen, dem lokalen Farbbedarf entsprechenden Versorgung der einzelnen Farbzonen ausgegeben werden. Weiterhin betrifft die Erfindung eine Einrichtung zum Zuführen von Druckfarbe in Farbkästen von Druckmaschinen, bestehend aus einer ortsfesten, dem Farbkasten zugeordneten Versorgungseinrichtung, die durch einen Rechner ansteuerbar ist , bestehend weiterhin aus einem im Farbkasten angeordneten Farbduktor, der sich über dessen gesamte Breite erstreckt und mit einem in mehrere Farbzonen unterteilten Farbmesser einen Dosierspalt bildet.The invention relates to a method for supplying printing ink in ink fountains of Printing machines, in which the color requirements of the ink zones are determined, these values on a computer are fed, processed there and control commands for zonal, the local color requirement appropriate supply of the individual color zones are output. Farther The invention relates to a device for supplying printing ink in ink fountains of Printing machines, consisting of a stationary supply device assigned to the ink fountain, which can be controlled by a computer, consisting of an im Ink duct arranged ink duct, which extends over its entire width and with forms a metering gap in a color meter divided into several color zones.
Aus der DE 23 24 462 C2 ist eine Einrichtung bekannt, durch die der Pegelstand im Farbkasten einer Druckmaschine auf einem konstanten Niveau gehalten werden kann. Das konstante Niveau wird angestrebt, um die im Farbkasten vorhandene Druckfarbe gering halten zu können. Dazu wird ein Farbrührer eingesetzt, der entlang des Farbduktors bewegt wird. Diese Bewegung erzeugt eine Welle, die von einem oberhalb des Farbrührers mitlaufenden Tasters als Maß für den Pegelstand erfaßt wird. Dabei wird die Farbzufuhr dann gesperrt, wenn der Pegelstand höher als das vorgegebene Niveau ist.From DE 23 24 462 C2 a device is known through which the level in the ink fountain a printing press can be kept at a constant level. The constant Level is sought in order to keep the printing ink in the ink fountain low. For this, a color stirrer is used, which is moved along the color ductor. This Movement creates a wave that comes from a button that moves above the color stirrer is measured as a measure of the water level. The ink supply is then blocked when the Level is higher than the specified level.
Diese Lösung soll bewirken, dass ein gleichmäßig niedriges Farbniveau im Farbkasten gehalten werden kann.This solution is said to cause an evenly low color level in the ink fountain can be held.
Es ist aber nicht möglich, die Farbe so zuzuführen, dass die Zuführung der Farbe in die einzelnen Farbzonen dem Farbbedarf entsprechend erfolgt. Dieses Problem soll mit der DE 195 12 727 A1 gelöst werden. Hier ist eine Farbkartusche verfahrbar auf einen Schlitten angeordnet. In Bewegungsrichtung vor der Farbkartusche ist ein mitfahrender Sensor angeordnet, der den Füllstand zonal detektiert und bei Unterschreitung des erforderlichen Niveaus einen Steuerbefehl ausgibt. Dieser bewirkt, dass die Farbkartusche eine entsprechende Farbmenge an die bedürftige Farbzone abgibt.However, it is not possible to feed the color in such a way that the color is fed into the individual Color zones according to the color requirements. This problem is said with the DE 195 12 727 A1 can be solved. Here a color cartridge can be moved on a sled arranged. A moving sensor is arranged in front of the ink cartridge in the direction of movement, which detects the level zonally and when the level falls below the required level issues a control command. This causes the color cartridge to have an appropriate amount of color to the needy color zone.
Diese Lösung hat den Nachteil, dass die zugeteilte neue Farbe in den einzelnen Zonen auf die vorhandene Farbe aufgesetzt wird und keine Vermischung der neuen mit der alten Farbe erfolgen kann. Das führt dazu, dass Farbe mit wechselnden rheologischen Eigenschaften zur Verarbeitung gelangt.This solution has the disadvantage that the assigned new color in the individual zones on the existing color is put on and there is no mixing of the new with the old color can. This leads to color with changing rheological properties Processing arrived.
Aufgabe der Erfindung ist es daher, ein Verfahren und eine Einrichtung zu entwickeln, durch die eine dem Farbbedarf entsprechende zonale Dosierung erfolgen kann, wobei die im Farbkasten befindliche Farbe mit der neu zudosierten Farbe intensiv vermischt werden soll.The object of the invention is therefore to develop a method and a device by the zonal dosing corresponding to the color requirement can take place, the one in the color box existing color should be mixed intensively with the newly added color.
Diese Aufgabe wird durch die Merkmale des 1. und des 15. Anspruchs gelöst. Die Erfindung erfährt ihre Weiterbildung in den jeweils untergeordneten Ansprüchen.This object is achieved by the features of the 1st and 15th claims. The invention undergoes further training in the respective subordinate claims.
Der Vorteil der erfindungsgemäßen Lösung besteht darin, dass nunmehr Farbe zur Verarbeitung gelangt, die über der gesamte Breite des Farbkasten konstante rheologischen Eigenschaften aufweist. Im Lauf des Druckvorganges wird über die gesamte Breite des Farbkastens ein bedarfsgerechtes Farbprofil aufrecht erhalten. Es wird immer mit einer minimalen Farbmenge im Farbkasten gearbeitet, so dass am Ende des laufenden Auftrags nur eine geringe Farbmenge im Farbkasten verbleibt.The advantage of the solution according to the invention is that now color for processing the rheological properties are constant over the entire width of the ink fountain having. In the course of the printing process, the entire width of the ink fountain maintain a needs-based color profile. It always comes with a minimal amount of paint worked in the color box so that at the end of the current job only a small one Color quantity remains in the ink fountain.

Wie aus der Figur 1 hervorgeht, besteht die erfindungsgemäße Einrichtung aus einem Farbkasten
1, dem ein Farbduktor 2 zugeordnet ist. Der Farbduktor 2 erstreckt sich über die gesamte
Breite des Farbkastens 1. An der dem Farbduktor 2 zugewandten Seite des Farbkastens
1 ist ein Farbmesser 3 angeordnet, dass in mehrere Abschnitte 3.1 ... 3.x unterteilt ist (siehe
hierzu Figur 2). Diese Abschnitte 3.1 ... 3.x realisieren sogenannte Farbzonen. Diesen sind
Farbdosierelemente 4 zugeordnet, die je nach Farbbedarf der entsprechenden Farbzonen den
betreffenden Abschnitt des Farbmesser 3 in einem definierten Abstand zum Farbduktor 2
stellen, so dass über die Länge des Farbduktor 2 zwischen diesem und dem Farbmesser 3 ein
Dosierspalt 5 gebildet wird. As can be seen from FIG. 1, the device according to the invention consists of a
Oberhalb des Farbduktors 2 ist an einer Halterung 6 eine Versorgungseinrichtung bzw. ein
Farbreservoir in Form einer Farbkartusche 7 angeordnet. Bevorzugt ist eine Lage in der Mitte
des Farbduktors, die Anordnung in den Randzonen außerhalb der Farbzonen ist aber auch
möglich. Die Farbkartusche 7 ist mit Auslaßventil 8 versehen, dass durch einen nicht dargestellten
Rechner ansteuerbar ist. Durch nicht dargestellte pneumatische Mittel oder andere
geeignete Mittel wird ein konstanter Druck auf das Innere der Farbkartusche 7 ausgeübt.Above the
Weiterhin ist dem Farbkasten 1 eine Traverse 9 zugeordnet, die sich über dessen gesamte

eine Farbspachtel 11 angeordnet ist. Diese besteht aus einer Aufnahme 12, einer Halterung
13 und einem Streichblatt 14. Das Streichblatt 14 ist beim Farbtransport so gestellt, dass
ein minimaler Spalt zwischen dem Streichblatt 14 und dem Farbduktor 2 und dem Streichblatt
14 und dem Farbkasten 1 gebildet wird. Der Halterung 13 ist in der Aufnahme 12 drehbar.
Weiterhin ist zur Überwachung des Füllstandes des Farbkasten 1 ein Sensor 15 fest an der

Mit dieser oben beschriebenen Einrichtung wird gemäß der Erfindung folgendes Verfahren realisiert:With this device described above, the following method according to the invention realized:
Der Farbbedarf der einzelnen Farbzonen wird ermittelt. Das erfolgt, indem dem Rechner Daten
über den laufenden Auftrag übermittelt werden. Diese Daten werden entweder von einem
Plattenscanner eingelesen oder können auch in Form der für den Auftrag bekannten Vorstufendaten
eingegeben werden. Weiterhin werden veränderliche maschinenbezogenen Daten,
wie zum Beispiel die Drehzahl des Farbduktors 2, permanent ermittelt und dem Rechner zur
Verfügung gestellt bzw. unveränderliche maschinenbezogene im Speicher des Rechners abgelegt.
Diese Daten werden im Rechner verarbeitet und - dem lokalem Farbbedarf entsprechende
- Steuerbefehle zur Versorgung der einzelnen Farbzonen ausgegeben.The color requirement of the individual color zones is determined. This is done by adding data to the calculator

Die zonale Versorgung der Farbzonen erfolgt erfindungsgemäß in Versorgungszyklen. Dabei
umfaßt ein Versorgungszyklus eine auftragsbezogene, durch den Rechner ermittelte Anzahl
Dosiervorgänge zur Versorgung der Farbzonen, wobei in der Regel pro Farbzone unterschiedliche
Mengen von Farbe dosiert werden oder auch einige Farbzonen nicht in jedem
Versorgungszyklus bedient werden. Das heißt, dass in bestimmte Farbzonen z.B. nur in jedem
3. Versorgungszyklus Farbe eingebracht werden muß. Innerhalb eines Versorgungszyklus
wird aber insgesamt so viel Farbe eingebracht, dass im Verlauf des diesem folgenden Versorgungszyklus
die Farbmenge in keiner Farbzone ein definitiv festgelegtes Minimum unterschreitet.
Damit soll verhindert werden, dass der Farbkasten 1 leergefahren wird.The zonal supply of the color zones takes place according to the invention in supply cycles. there
a supply cycle comprises an order-related number determined by the computer
Dosing processes for supplying the ink zones, usually different for each ink zone

This is to prevent the
Der Sensor 15 überwacht den Füllstand des Farbkastens 1 und sorgt dafür, dass sich die
Schwankungen des Farbniveaus im Farbkasten 1 innerhalb der vorgegebenen Werte halten.The
Die Dosierung geschieht nun auf folgende Weise:The dosage is now done in the following way:
Die erforderliche Farbmenge für die Versorgung der Farbzonen wird von der ortsfesten Farbkartusche
7 eingebracht. Dabei erfolgt die Dosierung vorteilhaft auf den Farbduktor 2, vorzugsweise
in dessen Mitte. Die Farbspachtel 11 schiebt dann die eingebrachte Farbmenge in
Richtung der Randzonen des Farbkasten 1 zu der versorgungsbedürftigen Farbzone. Die Farbe
muß also - in Bewegungsrichtung der Farbspachtel 11 gesehen - vor dieser eingebracht
werden. Das heißt, der Rechner ermittelt, welche Farbzone zu versorgen ist und in welchen
Bereich bezüglich der Ausgangslage der Farbspachtel 11 diese Farbzone liegt.The amount of ink required to supply the ink zones is provided by the
In einer anderen Ausführung ist die Versorgungsstelle der ersten oder letzten Farbzone des
Farbkastens zugeordnet ist und die eingebrachte Farbmenge wird durch die Farbspachtel 11
jeweils in Richtung der anderen, gegenüberliegenden Farbzonen verschoben. Dabei muß die
Versorgungsstelle außerhalb dieser Rand-Farbzone, aber noch im Bereich des Farbduktors 2
liegen.In another embodiment, the supply point of the first or last color zone is the
Color box is assigned and the amount of paint introduced is by the paint spatula 11th
each shifted in the direction of the other, opposite color zones. The
Supply point outside this edge color zone, but still in the area of the
Die Versorgung der Farbzonen innerhalb eines Versorgungszyklus erfolgt nach einem festgelegten
Modus, der von der Entfernung der zu versorgenden Farbzone von der Versorgungsstelle
abhängt. Dabei hat die jeweils weiter entfernt liegende versorgungsbedürftige Farbzone
den Vorrang. Das heißt, wenn die Versorgungsstelle in der Mitte des Farbduktors 2 liegt,
werden zuerst die Rand-Farbzonen mit der für den laufenden Versorgungszyklus erforderlichen
Farbmenge versorgt. Liegt die Versorgungsstelle außerhalb des Bereichs der Farbzonen,
so hat die gegenüberliegende Randzone die Priorität. The ink zones are supplied within a supply cycle according to a defined one
Mode that depends on the distance of the ink zone to be supplied from the supply point
depends. The color zone in need of care, which is further away, has
the priority. That means if the supply point is in the middle of the
Für den Dosiervorgang pro Farbzone gibt es zwei Varianten. Einmal kann die für die entsprechende
Versorgung der Farbzone erforderliche Farbmenge in einem Gang eingebracht werden.
Die Farbmenge variiert also, so dass das Auslaßventil 8 über die Zeit gesteuert werden
muß. Dabei wird davon ausgegangen, dass infolge des konstanten Drucks in der Farbkartusche
die ausströmende Menge über die Zeit konstant ist.There are two variants for the dosing process per ink zone. Once the appropriate one
Supply of the ink zone required amount of ink can be introduced in one pass.
The amount of paint thus varies, so that the
Es ist aber auch möglich, das Auslaßventil 8 periodisch zu öffnen, so dass pro Öffnung eine
diskrete Menge an Farbe eingebracht wird. Dieser Vorgang wird dann so oft wiederholt, bis
der für den laufenden Versorgungszyklus erforderliche Farbbedarf der versorgungsbedürftigen
Farbzone gedeckt ist. Die Farbspachtel 11 kann dann jede dieser diskreten Mengen zur
bedürftigen Farbzone verbringen oder auch so lange in der Ausgangsstellung verweilen, bis
die erforderliche Farbmenge zur Versorgung der Farbzone eingebracht ist und dann ihre Routinebewegung
ausführen.But it is also possible to periodically open the
Nachdem die Farbspachtel 11 die Farbe zu der zu versorgenden Farbzone gebracht hat, kehrt
sie zur Versorgungsstelle zurück. Dabei kann das Streichblatt 14 aus seiner Arbeitslage gedreht
werden. Das heißt, das Streichblatt 14 der Farbspachtel 11, das zum Zweck des Farbtransports
im rechten Winkel zur Transportrichtung steht, wird bei der Rückkehrbewegung in
Transportrichtung gedreht, um zu verhindern, dass das sich im Farbkasten 1 aufbauende
Farbprofil bei dieser Bewegung zerstört wird. Die Geschwindigkeit, mit der diese Rückkehrbewegung
erfolgt, beträgt ein Mehrfaches der Geschwindigkeit, die beim Verschieben der
Farbe gewählt wird.After the
In einer anderen Ausgestaltung des Verfahrens wird die Farbspachtel 11 während des Farbtransports
in Rotation versetzt. Dabei wird mit der Transportbewegung auch ein Rühren der
