Bei einem aus der US-PS 5,402,724 bekannten Verfahren dieser Art wird die Förderrichtung der das Lösungsmittel während der Spülphase durch die Farbkammer leitenden Pumpe mehrmals umgekehrt, um durch die dadurch erfolgte Änderung der Strömungsrichtung des Lösungsmittels eine gründliche Spülung der Farbkammer zu erreichen.In a method of this type known from US Pat. No. 5,402,724 becomes the direction of delivery of the solvent during the rinsing phase reversed several times by the pump conducting the ink chamber, in order to change the direction of flow of the Solvent to achieve a thorough rinsing of the ink chamber.
Nach der Beendigung eines Druckauftrages oder bei einem Wechsel der Druckfarbe ist es erforderlich, die Rakelvorrichtungen zu reinigen, wobei es nicht nur notwendig ist, sämtliche Farbreste aus der Farbkammer und von der Rasterwalze zu entfernen, sondern zusätzlich müssen auch die Zu- und Abführungsleitungen für die Farbe gereinigt werden.After finishing a print job or after a change the ink it is necessary to add the squeegee devices clean, it is not only necessary to remove all paint residues remove from the ink chamber and from the anilox roller, but in addition, the supply and discharge lines for the Paint to be cleaned.
Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs angegebenen Art zu schaffen, nach dem sich in einfacher und gründlicher Weise sämtliche Farbreste nicht nur aus der Farbkammer der Rakelvorrichtung, sondern auch aus den Zu- und Abführungsleitungen entfernen lassen.The object of the invention is therefore a method of the beginning specified type to create, after in simple and thoroughly remove all paint residues not only from the ink chamber the doctor blade device, but also from the supply and discharge lines have it removed.
Erfindungsgemäß wird diese Aufgabe bei einem Verfahren der eingangs angegebenen Art dadurch gelöst, daß die Farbe aus der Farbkammer über die Abführungsleitung oder -leitungen zurück in den Farbtank gepumpt wird, daß anschließend aus einem Lösungsmitteltank über die Zuführungsleitung oder -leitungen aus einem Lösungsmitteltank Lösungsmittel in die Farbkammer gepumpt und über die Abführungsleitungen während eines vorbestimmten Zeitraums in den Farbtank geleitet wird, daß anschließend das noch durch Farbe verschmutzte Lösungsmittel während eines vorbestimmten Zeitraums in einen Schmutztank gepumpt wird, daß anschließend die Lösungsmittelzufuhr aus dem Lösungsmitteltank unterbrochen und das Lösungsmittel in den Schmutztank gepumpt wird, daß anschließend frisches Lösungsmittel über die Zuführungsleitung in die Farbkammer gepumpt, die Ansaugleitung zum Lösungsmitteltank geschlossen und das Lösungsmittel über die Zuführungs- und Abführungsleitungen in einem geschlossenen Spülkreislauf für eine bestimmte Zeit gepumpt wird und daß anschließend das im Kreislauf geförderte Lösungsmittel in den Schmutztank geleitet wird.According to the invention, this object is achieved in a method of the beginning specified type solved in that the color from the ink chamber via the discharge line or lines back into the Color tank is pumped that subsequently from a solvent tank via the feed line or lines from a solvent tank Solvent pumped into the paint chamber and over the drain lines in for a predetermined period of time the paint tank is routed, that then by paint contaminated solvents for a predetermined period of time is pumped into a dirt tank that the Solvent supply from the solvent tank is interrupted and the solvent is pumped into the dirt tank that then fresh solvent via the feed line into the Ink chamber pumped, the suction line to the solvent tank closed and the solvent via the supply and discharge lines in a closed rinse cycle for a specific one Time is pumped and then that in the cycle conveyed solvent is fed into the dirt tank.
Die einzelnen Schritte zur Reinigung der Rakelvorrichtung und der zugehörigen Leitungen lassen sich nacheinander durchführen, wobei der Reinigungsprozeß von einem Rechner gesteuert werden kann. Erfindungsgemäß wird während der ersten Reinigungsphase das noch stark mit Farbe angereicherte Lösungsmittel in den Farbtank geleitet, weil die dadurch erfolgte Verdünnung der Farbe onne weiteres in Kauf genommen werden kann und sich überschüssiges Lösungsmittel wieder verflüchtigt. Die weiteren Verfahrensschritte zielen darauf ab, einmal eine gründliche Reinigung der Rakelvorrichtung zu erreichen und zum anderen einen sparsamen Lösungsmittelverbrauch zu gewährleisten, weil das in den Schmutztank geleitete und mit Farbe angereicherte Lösungsmittel besonders entsorgt werden muß.The individual steps for cleaning the doctor device and the associated lines can be carried out one after the other, the cleaning process being controlled by a computer can. According to the invention during the first cleaning phase the solvent, which is still heavily enriched with color, into the paint tank headed because the resulting thinning of the paint one more can be accepted and excess The solvent evaporates again. The further process steps aim at once a thorough cleaning of the To reach doctor blade device and secondly an economical To ensure solvent consumption because that is in the dirt tank directed and color-enriched solvents especially must be disposed of.
Zweckmäßigerweise wird die Farbe der Farbkammer durch eine in deren Mitte befindliche Zuführungsleitung zugeführt und durch seitliche Abführungsleitungen aus dieser wieder abgesaugt.The color of the ink chamber is expediently replaced by an in the middle of the feed line is fed in and through side discharge lines sucked out of this again.
Um auch die Zuführungsleitung für die Farbe vollständig zu reinigen, wird in vorteilhafter Weise während jeder Spülphase zeitweise eine der endseitigen Abführleitungen gesperrt und Lösungsmittel auch durch die Zuführungsleitung abgesaugt.To also completely clean the paint supply line, is advantageous at times during each rinsing phase one of the end discharge lines blocked and solvent also sucked off through the feed line.
Wird der Druckbetrieb mit einer neuen Farbe wieder aufgenommen, wird zweckmäßigerweise bei dem Andruck mit neuer Farbe diese für einen vorbestimmten Zeitraum in den Schmutztank gepumpt. Hierdurch wird sichergestellt, daß die neue Farbe nicht noch zu stark mit Resten von Lösungsmittel verdünnt wird. Die in den Schmutztank strömende Farbe läßt sich beobachten, so daß der Abfluß gestoppt werden kann, wenn die im Kreislauf befindliche Farbe von einwandfreier Qualität ist.If printing is resumed with a new color, will be useful when printing with new ink pumped into the dirt tank for a predetermined period of time. Hereby it ensures that the new color is not yet too is heavily diluted with residues of solvent. The in the Dirt tank pouring paint can be observed, so that the drain can be stopped when the color in circulation is of impeccable quality.
Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß während des Abpumpens der Farbe aus der Farbkammer die Farbauftragswalze mit einer gegenüber dem Druckbetrieb geringeren Weiterlaufdrehzahl angetrieben wird. According to a preferred embodiment of the invention, that while the ink is being pumped out of the ink chamber Ink application roller with a lower one compared to printing Continued speed is driven.
Zur Erhöhung des Reinigungseffekt ist nach einer weiteren vorteilhaften Ausgestaltung der Erfindung vorgesehen, daß während der Spülphasen die Farbauftragswalze mit einer gegenüber dem Druckbetrieb höheren Drehzahl angetrieben wird. Diese höhere Drehzahl verursacht höhere die Reinigung begünstigende Turbolenzen.To increase the cleaning effect, another is advantageous Embodiment of the invention provided that during the rinse phases the inking roller with one opposite Printing operation is driven at higher speed. This higher Speed causes higher turbulences that favor cleaning.
