Abstract
Description
Die Erfindung betrifft ein Verfahren zum Zuführen von Druckfarbe in Farbkästen von Druckmaschinen, bei dem die Druckmaschine zur Farbversorgung einen Farbkasten aufweist, dem ein mit Farbdosierelementen zusammenwirkender Farbduktor zugeordnet ist, so dass Farbzonen zur differenzierten Versorgung der Bedruckstoffe gebildet werden, der Farbbedarf der Farbzonen oder von Farbzonengruppen ermittelt wird, diese Werte einem Rechner zugeführt und dort verarbeitet werden, der Rechner dem lokalen Farbbedarf adäquate Steuerbefehle zur Versorgung der einzelnen Farbzonen oder Farbzonengruppen ausgibt und eine parallel zum Farbduktor verfahrbare Farbspendeeinrichtung die farbbedürftigen Farbzonen oder Farbzonengruppen versorgt.The invention relates to a method for supplying printing ink in ink fountains of printing machines, in which the printing machine for ink supply has an ink fountain, the a color guide interacting with ink metering elements is assigned, so that Ink zones for the differentiated supply of printing materials are formed, the ink requirement the color zones or groups of color zones is determined, these values fed to a computer and processed there, the computer commands appropriate to the local color requirements to supply the individual ink zones or ink zone groups and one Paint dispensing device that can be moved parallel to the ink fountain roller or ink zone groups.
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 Taster 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 aimed at to keep the printing ink in the ink fountain low to be able to. For this, a color stirrer is used, which is moved along the color ductor. This movement creates a wave that comes from a moving one above the paint stirrer Button is recorded as a measure of the water level. The ink supply is then blocked, if 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 intended to ensure that a uniformly low color level is kept in the ink fountain can be.
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 einem 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 paint in such a way that the paint 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 the direction of movement in front of the ink cartridge, 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 a corresponding Gives the amount of paint to the color zone in need.
Der Nachteil dieser Lösung besteht darin, dass bei Auftragsende der Farbkasten nicht hinreichend leer gedruckt werden kann. Da bedarfsgerecht zudosiert wird, verbleibt bei Auftragsende ein unebenes Oberflächenprofil mit Bereichen, die infolge ihres geringen Farbbedarfs Farbanhäufungen aufweisen. Diese Farbanhäufungen können nicht mehr verdruckt werden und verbleiben im Farbkasten der Druckmaschine. The disadvantage of this solution is that the ink fountain is not sufficient at the end of the job can be printed blank. Since the dosage is added as required, it remains at the end of the order an uneven surface profile with areas due to their low color requirement Have color clusters. These color clusters can no longer be printed are and remain in the ink fountain of the printing press.
Aus der DE 44 24 591 C1 ist eine Vorrichtung zur Zufuhr von Druckfarbe aus einer Farbspendeeinrichtung bekannt, bei der zum Leeren des Farbkastens am Auftragsende ein auf die zu verdruckende Produktmenge einstellbarer Vorwahlzähler angeordnet ist. Dieser ist schaltungstechnisch mit der Farbspendeeinrichtung verbunden. Dadurch kann vor Auftragssende durch ein Steuersignal in Abhängigkeit von der zu bedruckenden Produktmenge die Farbzufuhr von der Farbspendeeinrichtung gestoppt werden.DE 44 24 591 C1 describes a device for supplying printing ink from an ink dispenser known, when emptying the ink fountain at the end of the order the quantity of adjustable preselect counter to be printed is arranged. This is technically connected to the paint dispenser. This can be done before the order ends by a control signal depending on the amount of product to be printed Ink supply from the ink dispenser can be stopped.
Auch durch diese Einrichtung ist es infolge des unebenen Oberflächenprofils nicht möglich, den Farbkasten rückstandsfrei zu leeren.Due to the uneven surface profile, this device also makes it impossible to empty the ink fountain residue-free.
Aufgabe der Erfindung ist es daher, ein Verfahren und eine Einrichtung zu entwickeln, durch die eine dem Farbbedarf entsprechende zonale Dosierung erfolgen und der Farbkasten bei Auftragsende oder bei Auftragswechsel weitgehend rückstandsfrei leer gefahren werden kann.The object of the invention is therefore to develop a method and a device by the zonal dosing corresponding to the color requirement takes place and the color box at End of order or when changing orders are left largely empty can.
Diese Aufgabe wird durch die Merkmale des 1. Anspruchs gelöst. Die Erfindung erfährt ihre Weiterbildung in den jeweils untergeordneten Ansprüchen.This object is achieved by the features of the first claim. The invention experiences its Further training in the respective subordinate claims.
Der Vorteil der erfindungsgemäßen Lösung besteht darin, dass bei Auftragsende oder bei Auftragswechsel der Farbkasten nahezu leer gefahren ist. Dadurch entfällt neben der Einsparung von Farbe die aufwendige manuelle Entleerung des Farbkastens durch den Drukker.The advantage of the solution according to the invention is that at the end of the order or at Order change the ink fountain is almost empty. In addition to the savings, this also eliminates of color the time-consuming manual emptying of the ink fountain by the printer.

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 (siehe Figur 2). 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 eine Traverse 6 angeordnet, die sich parallel zum Farbduktor
2 erstreckt. Auf der Traverse 6 läuft ein auf dieser verfahrbare Schlitten 7.1, an dem eine
Farbspendeeinrichtung 7, hier in Form einer Farbkartusche 7.2, befestigt ist.A
Die Farbkartusche 7.2 ist mit einem Auslassventil 7.3 versehen, das 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 7.2 ausgeübt.The color cartridge 7.2 is provided with an outlet valve 7.3, which by a not shown Computer can be controlled. By pneumatic means, not shown, or others suitable means, a constant pressure is exerted on the inside of the ink cartridge 7.2.
Zur Überwachung des Füllstandes des Farbkastens 1 ist dem Schlitten 7.1 ein Sensor 8
zugeordnet.To monitor the fill level of the
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 eingegeben 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. werden 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.
Dabei ist es auch möglich, dass mehrere Farbzonen zu einer Farbzonengruppe zusammengefasst
werden, die dann und im Rechner wie eine Farbzone behandelt wird.The color requirement of the individual color zones is determined. This is done by the calculator
Data about the current job can be entered. This data is either from
read a plate scanner or can also in the form of the known for the job
Prepress data can be entered. Furthermore, changing machine-related
Data, such as the speed of the
Die Dosierung geschieht nun auf folgende Weise:The dosage is now done in the following way:
Mit der Farbkartusche 7.2 wird der Sensor 8 auf der ersten Traverse 6 parallel zum
Farbduktor 2 verfahren. Dieser tastet den Füllstand der einzelnen Farbzonen oder Farbzonengruppen
ab. Wird der Füllstand im Farbkasten 1 in der abgetasteten Farbzone oder
Farbzonengruppe unterschritten, dosiert die Farbkartusche 7.2 eine definitiv festgelegte
Menge. Die Dosierung erfolgt dabei auf dem Farbduktor 2.With the color cartridge 7.2, the
Während des Dosiervorganges wird neben der Höhe des Füllstandes gleichzeitig die Position der Farbkartusche 7.2 detektiert und an den Rechner übermittelt.In addition to the level, the position is also displayed during the dosing process the color cartridge 7.2 is detected and transmitted to the computer.
Über eine bekannte, hier nicht dargestellte Zähleinrichtung wird die Produktmenge erfasst. Das heißt, die bedruckten Druckbögen werden gezählt und an den Rechner übermittelt. Gleichzeitig wird der Farbverbrauch ermittelt und ebenfalls dem Rechner zur Verfügung gestellt. Mit diesen Daten ist der Rechner nunmehr in der Lage, den Farbbedarf pro Produkteinheit zu ermitteln. Da die auftragsbezogenen Daten bekannt sind, kann der Rechner unter Einbeziehung der maschinenbezogenen Daten und der insgesamt zu verdruckenden Produktmenge den Zeitpunkt ermitteln, wann für die Farbzone oder Farbzonengruppe mit dem geringsten Farbbedarf keine Farbzufuhr bis zum Auftragsende mehr erforderlich ist. Das heißt, dass in dieser Farbzone oder Farbzonengruppe ausreichend Farbe bis zu Bedrucken des letzten Druckbogens vorhanden ist. Beim Erreichen dieses Zeitpunktes wird ein Restdosiervorgang eingeleitet.The quantity of product is recorded via a known counting device, not shown here. This means that the printed sheets are counted and sent to the computer. At the same time, the color consumption is determined and also made available to the computer. With this data, the computer is now able to determine the color requirement per product unit to investigate. Since the order-related data is known, the computer can including the machine-related data and the total to be printed Product quantity determine the time when for the ink zone or ink zone group with the least amount of paint is no longer required until the end of the job. This means that there is enough color up to printing in this ink zone or ink zone group of the last printed sheet is available. When this time is reached, a Residual dosing started.
Dieser besteht darin, dass jetzt nur noch diejenigen Farbzonen oder Farbzonengruppen bedient werden, die die zugeführte Farbe bis zum vorausberechneten Auftragsende noch verbrauchen können.This consists of the fact that now only those color zones or color zone groups are served who still consume the supplied color up to the pre-calculated order end can.
Dabei kann eine Änderung der Dosierzyklen im Restdosiervorgang erforderlich werden. Das bedeutet, dass die diskrete Menge, die pro Dosiergang in die Farbzone oder Farbzonengruppe eingebracht wird, verringert wird. In Folge davon muss dann die Anzahl der Dosiergänge pro Zeiteinheit erhöht werden, um für die Farbzonen mit hohen Farbbedarf den Verbrauch abzudecken. Die bedürftige Farbzone oder Farbzonengruppe muss häufiger bedient werden, als das beim Hauptdosiervorgang erforderlich war.It may be necessary to change the dosing cycles in the remaining dosing process. The means that the discrete amount per dose in the ink zone or ink zone group is introduced, is reduced. As a result, the number of dosing steps must be followed per unit of time can be increased to consumption for the ink zones with high ink requirements cover. The color zone or ink zone group in need must be served more frequently than was necessary during the main dosing process.
In einer weiteren Ausführung der Erfindung wird vorgeschlagen, beim Restdosiervorgang die Maschinengeschwindigkeit, das heißt also die Drehzahl der Eintourenwelle, abzusenken. Der Druckvorgang erfolgt dann langsamer. Damit kann die Geschwindigkeit der Dosierung mit den geringen diskreten Farbmengen beibehalten werden, da die Farbversorgungseinrichtung nunmehr in der Lage ist, die Farbzonen und Farbzonengruppen mit dem höchsten Farbverbrauch bis zum vorausberechneten Auftragsende mit Farbe zu versorgen. In a further embodiment of the invention, it is proposed that the Reduce machine speed, i.e. the speed of the single-speed shaft. The printing process is then slower. This can speed up the dosage can be maintained with the small discrete amounts of paint since the paint supply device is now able to identify the color zones and color zone groups with the highest To supply color consumption with color up to the pre-calculated order end.
