Description

Die Erfindung betrifft eine Wascheinrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a washing device according to the preamble of patent claim 1.

Durch die gattungsgemäße FR-A-15 47 793 ist eine Waschvorrichtung bekannt geworden, bei der eine achsparallele oder spiralförmige Nuten aufweisende harte Waschwalze direkt mit der zu waschenden Oberfläche, z. B. einem Gummituch zusammenwirkt. Hierdurch besteht die Gefahr der Beschädigung der zu waschenden Fläche. Die Reinigungswirkung ist dadurch stark vermindert, daß es nicht möglich ist, den zu waschenden Überzug durch einen Walkvorgang zeitweise zu dehnen und während dieser Dehnphase Druckfarbe mittels der waschwalze "abzuschaben". Mit der Ausführung mit spiralförmigen Nuten ist kein gründliches "Abschaben" möglich, es wird vielmehr immer ein dünner Farbfilm übrigbleiben. Bei der Ausführung mit den parallelen Nuten gilt im allgemeinen das ebengesagte mit dem Zusatz, daß das Waschen feinste Altfarbestreifen auf der zu reinigenden Fläche hinterlassen kann.Through the generic FR-A-15 47 793 a washing device has become known in which an axially parallel or spiral-shaped grooves having a hard washing roller directly with the surface to be washed, for. B. interacts with a rubber blanket. This creates the risk of damaging the surface to be washed. The cleaning effect is greatly reduced in that it is not possible to temporarily stretch the coating to be washed by means of a flexing process and to “scrape off” printing ink by means of the washing roller during this stretching phase. With the design with spiral grooves, thorough "scraping" is not possible, rather a thin film of paint will always remain. In the case of the design with the parallel grooves, what has just been said applies with the addition that washing can leave the finest streaks of old paint on the surface to be cleaned.

Der Erfindung liegt die Aufgabe zugrunde, eine rakellose und weitestgehendst wartungsfreie Wascheinrichtung für Farbwerke bei Druckmaschinen zu schaffen, welche bei hoher Reinigungsfähigkeit die schädlichen Nebenwirkungen der Rakelblätter vermeidet.The invention has for its object to provide a flawless and largely maintenance-free washing device for inking units in printing presses, which have the harmful side effects with high cleanability which avoids squeegee blades.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Patentanspruches 1 gelöst.This object is achieved by the characterizing part of patent claim 1.

Die erzielten Vorteile durch die Erfindung bestehen insbesondere darin, daß auch die letzten Farbreste vollständig von der zu reinigenden Farbwalze entfernt werden, da ein Abrakeln vermieden wird. Durch die Verwendung von rotierenden Teilen werden die schädlichen Wirkungen des Rakelblattes bei einem möglichen Trockenlauf der Einrichtung, wie Riefenbildung, vermieden. Die Wascheinrichtung ist weitestgehendst wartungsfrei, da keine Rakelblätter von anhaftenden Farbresten zu befreien sind. Weiterhin ist die Einrichtung universell an verschiedene getriebene Reibwalzen 3 anbaubar, so wie diese Reibwalzen 3 in Fig. 1 dargestellt sind. Dabei muß die Drehrichtung der Reibwalze nicht berücksichtigt werden, da die angetriebene Gummiwalze der Wascheinrichtung drehrichtungsumkehrbar angetrieben ist.The advantages achieved by the invention are, in particular, that even the last ink residues are completely removed from the ink roller to be cleaned, since doctoring is avoided. The use of rotating parts avoids the harmful effects of the squeegee blade when the device runs dry, such as scoring. The washing facility is as far as possible maintenance-free, since no squeegee blades can be freed from adhering paint residues. Furthermore, the device can be attached universally to various driven friction rollers 3, as shown by these friction rollers 3 in FIG. 1. The direction of rotation of the friction roller does not have to be taken into account, since the driven rubber roller of the washing device is reversibly driven in the direction of rotation.

Gemäß Fig. 1 ist ein Farbwerk einer Druckmaschine dargestellt, welches einen Plattenzylinder 1 aufweist, an welchem vier Auftragswalzen 2 anliegen. Mit zwei Auftragswalzen 2 steht jeweils ein Reibzylinder 3 in Verbindung. Die zwei Reibzylinder 3 sind über zwei Zwischenwalzen 4 mit einem dritten Reibzylinder 3 in Verbindung. Zwei weitere Zwischenwalzen 4 sind mit einem Nacktzylinder 6 verbunden, der wiederum seinerseits über einen Farbheber 7 mit einem Duktor 8 in Verbindung steht. An eine äußere Auftragswalze 2 ist ein Feuchtwerk 9 angeschlossen. Mit einer der beiden mit den Auftragswalzen 2 in Verbindung stehenden Reibzylindern 3 ist die erfindungsgemäße Wascheinrichtung, die insgesamt mit 11 bezeichnet ist, in Kontakt. Die in Fig. 1 dargestellten Zylinder, Walzen und anderen Einrichtungen sind gemäß ihrer Funktion in Lagern oder Halterungen eines nicht dargestellten Maschinengestells befestigt.1, an inking unit of a printing press is shown, which has a plate cylinder 1, on which four application rollers 2 rest. A distribution cylinder 3 is connected to two application rollers 2. The two distribution cylinders 3 are connected to a third distribution cylinder 3 via two intermediate rollers 4. Two further intermediate rollers 4 are connected to a naked cylinder 6, which in turn is connected to a ductor 8 via an ink lifter 7. A dampening unit 9 is connected to an outer application roller 2. With one of the two distribution cylinders 3 connected to the application rollers 2 the washing device according to the invention, which is designated as a whole by 11, is in contact. The cylinders, rollers and other devices shown in Fig. 1 are attached according to their function in bearings or holders of a machine frame, not shown.

Gemäß Fig. 2 ist die vergrößerte Darstellung der erfindungsgemäßen Wascheinrichtung 11 in Ruhestellung gezeigt. In einem Gehäuse 12 mit etwa U-förmigem Querschnitt und seitlicher Öffnung sind zwei Walzen untergebracht, eine Polygonwalze 13 und eine Gummiwalze 14. Beide Walzen 13; 14 sind mit ihren Achsstümpfen im Gehäuse 12 gelagert und so nebeneinander angeordnet, daß die Mantelfläche der Polygonwalze 13 in dem Kontaktbereich A in die Mantelfläche der Gummiwalze 14 eindringt. Die Gummiwalze 14 besitzt einen Gummiüberzug mit einer Härte von max. 15° Shore. Die Polygonwalze 13 ist an ihrer Oberfläche mit einem Kunststoffüberzug versehen. Die Polygonwalze 13 besitzt gemäß der Darstellung nach Fig. 2 an ihrem Umfang eine Vielzahl verteilter Flächen B, welche in axialer Richtung gesehen, einen Drall besitzen, was eine bessere Laufruhe beider Walzen 13; 14 zur Folge hat. Die Gummiwalze 14 ist durch einen nicht dargestellten Motor drehzahlregelbar in Pfeilrichtung C angetrieben. Gleichzeitig wird die Polygonwalze 13 über einen nicht dargestellten Antrieb, beispielsweise einem Zahnriemen mit gleicher Drehzahl, jedoch in entgegengesetzter Richtung gemäß Pfeilrichtung D angetrieben. Der Antrieb kann jedoch so ausgelegt sein, daß die Drehzahl und somit die Umfangsgeschwindigkeit der Polygonwalze 13 kleiner oder größer ist als die Umfangsgeschwindigkeit der Gummiwalze 14. Die Oberfläche der Polygonwalze 13 ist in tangentialer Richtung mittels sich in axialer Richtung erstreckender auf Düsenleisten 16; 17 angeordneten Flachstrahldüsen besprühbar. Die Strahlrichtung der Flachstrahldüsen verläuft gegensinnig. Die Düsenleisten 16; 17 werden durch eine Reinigungsmittelzuführung 18 gespeist. Der Ablauf des Waschmittels, vermischt mit Farbresten u. dgl. erfolgt an der tiefsten Stelle des Gehäuses 12 in einer Waschmittelabführung 19. Zwischen Waschmittelzuführung 18 und Waschmittelabführung 19 ist über nicht dargestellte Leitungen ein Filter, ein Vorratsbehälter und eine Pumpe eingeschaltet. Im Inneren des Gehäuses 12 ist in Höhe der Achse der Polygonwalze 13 eine im Querschnitt dachförmige Spritzwand 21 angeordnet, deren First 22 sich in Höhe der Achsen beider Walzen 13; 14 befindet. Dadurch ergibt sich eine Verringerung des Abstandes E zwischen dem First 22 und der Oberfläche der Polygonwalze 13. Das Gehäuse 12 ist in Pfeilrichtung F auf Führungen 23; 24 beispielsweise durch den Kolben 26 eines Arbeitszylinders verschiebbar, so daß die Wascheinrichtung 11 im Betriebszustand in Wirkverbindung kommt mit dem Reibzylinder 3.2, the enlarged view of the washing device 11 according to the invention is shown in the rest position. In a housing 12 with an approximately U-shaped cross section and a lateral opening, two rollers are accommodated, a polygon roller 13 and a rubber roller 14. Both rollers 13; 14 are mounted with their stub axles in the housing 12 and arranged side by side so that the outer surface of the polygon roller 13 penetrates into the outer surface of the rubber roller 14 in the contact area A. The rubber roller 14 has a rubber coating with a hardness of max. 15 ° shore. The polygon roller 13 is provided on its surface with a plastic coating. According to the representation according to FIG. 2, the polygon roller 13 has a plurality of distributed surfaces B on its circumference, which seen in the axial direction have a swirl, which improves the smooth running of both rollers 13; 14 results. The rubber roller 14 is driven in a speed-adjustable manner in the arrow direction C by a motor, not shown. At the same time, the polygon roller 13 is driven by a drive, not shown, for example a toothed belt at the same speed, but in the opposite direction according to arrow direction D. However, the drive can be designed so that the speed and thus the peripheral speed of the Polygon roller 13 is smaller or greater than the peripheral speed of the rubber roller 14. The surface of the polygon roller 13 is in the tangential direction by means of nozzle bars 16; 17 arranged flat spray nozzles sprayable. The jet direction of the flat jet nozzles runs in opposite directions. The nozzle strips 16; 17 are fed by a cleaning agent supply 18. The drain of the detergent, mixed with paint residues u. The like. At the deepest point of the housing 12 in a detergent discharge 19. Between the detergent supply 18 and detergent discharge 19, a filter, a reservoir and a pump is switched on via lines not shown. Arranged in the interior of the housing 12 at the level of the axis of the polygon roller 13 is a bulkhead 21 which is roof-shaped in cross section, the ridge 22 of which extends at the level of the axes of both rollers 13; 14 is located. This results in a reduction in the distance E between the ridge 22 and the surface of the polygon roller 13. The housing 12 is in the arrow direction F on guides 23; 24 displaceable, for example, by the piston 26 of a working cylinder, so that the washing device 11 comes into operative connection with the distribution cylinder 3 in the operating state.

Fig. 3 zeigt die Einzelheit X nach Fig. 2 in vergrößerter Darstellung. Der angetriebene Reibzylinder 3 nach Fig. 2 läuft in Pfeilrichtung G um, also gegenläufig zur Drehrichtung C der Gummiwalze 14 und transportiert mit seinen Flächen B Reinigungsmittel 28 von den Düsenleisten 17; 16 in den Bereich H der Polygonwalze 13. Im Kontaktbereich A dringen die Flächen und Kanten der Polygonwalze 13 in die Oberfläche der Gummiwalze 14 ein. Die vom Reibzylinder 3 übertragene, und auf der Gummiwalze 14 haftende Farbschicht 27 wird infolge der in Pfeilrichtung C umlaufenden Gummiwalze 14 in den Kontaktbereich A gegen die Kanten der Polygonwalze 13 geschoben. Es kommt zu einer Vermischung der Farbschicht 27 mit dem von der Polygonwalze 13 zugeführten Reinigungsmittel 28. Durch die in koaxialer Richtung auf dem Umfang der Polygonwalze 13 mit einem Drall laufenden Flächen B wird gleichzeitig ein Rühreffekt erzielt, der die Farbschicht 27 im Bereich A weiter löst. Bei weiterer Drehung der Walzen 13; 14 in der angegebenen Drehrichtung C; D kommt eine Fläche B im Bereich A in Kontakt mit der Gummiwalze 14. Dies hat einen Quetscheffekt zur Folge. Bei weiterer Drehung der Walzen 13; 14 kommt es zum Abscheren des nunmehrigen Gemisches aus Teilen der Farbschicht 27 und des Reinigungsmittels 28' und es erfolgt ein Abtransport des genannten Gemisches auf der Polygonwalze 13 in Pfeilrichtung D. Dieses Gemisch 27; 28' wird von der Oberfläche der Polygonwalze 13 durch die Düsenleisten 17; 16 abgesprüht und geht durch die Waschmittelabführung 19 zur Filtration und wird über eine Pumpe wieder den Düsenleisten 16; 17 zugeführt. Zwischengeschaltet ist noch ein Vorratsbehälter, welcher ebenfalls, wie die Pumpe und die Filtration, nicht dargestellt ist.Fig. 3 shows the detail X of FIG. 2 in an enlarged view. The driven distribution cylinder 3 according to FIG. 2 rotates in the direction of the arrow G, that is, in the opposite direction to the direction of rotation C of the rubber roller 14, and with its surfaces B it transports cleaning agents 28 from the Nozzle strips 17; 16 in the area H of the polygon roller 13. In the contact area A, the surfaces and edges of the polygon roller 13 penetrate into the surface of the rubber roller 14. The ink layer 27 transferred from the distribution cylinder 3 and adhering to the rubber roller 14 is pushed into the contact area A against the edges of the polygon roller 13 as a result of the rubber roller 14 rotating in the direction of arrow C. The ink layer 27 is mixed with the cleaning agent 28 supplied by the polygon roller 13. The surfaces B running in the coaxial direction on the circumference of the polygon roller 13 with a swirl simultaneously achieve a stirring effect which further loosens the ink layer 27 in area A. . Upon further rotation of the rollers 13; 14 in the specified direction of rotation C; D, a surface B in area A comes into contact with the rubber roller 14. This results in a squeezing effect. Upon further rotation of the rollers 13; 14 the now mixture of parts of the ink layer 27 and the cleaning agent 28 'is sheared off and the mixture mentioned is transported away on the polygon roller 13 in the direction of the arrow D. This mixture 27; 28 'is from the surface of the polygon roller 13 through the nozzle strips 17; 16 sprayed and passes through the detergent discharge 19 for filtration and the nozzle strips 16; 17 fed. A storage container is also interposed, which, like the pump and the filtration, is also not shown.

Ein Teil des auf der Polygonwalze 13 zugeführten Reinigungsmittels 28 wird gleich auf der gesäuberten Gummiwalze 14 in Pfeilrichtung C als Reinigungsmittel 28'' wieder abgeführt.Part of the fed on the polygon roller 13 Cleaning agent 28 is immediately removed again on the cleaned rubber roller 14 in the direction of arrow C as cleaning agent 28 ″.

Gemäß Fig. 4 ist eine weitere Ausführungsvariante nach Fig. 2 dargestellt. Unter der Polygonwalze 13 und innerhalb des Gehäuses 12 ist eine mit Reinigungsmittel 28 gefüllte Wanne 29 angeordnet, welche an ihrem Boden mit einem Schwingungserzeuger 31 verbunden ist und in welche die Oberfläche der Polygonwalze 13 eintaucht. Der Schwingungserzeuger 31 ruht auf Schwingungsisolatoren 32, die mit dem Boden des Gehäuses 12 verbunden sind. Der Schwingungserzeuger 31 arbeitet im Ultraschallbereich und entfernt die eventuell noch auf der Polygonwalze 13 verbliebenen Farbrückstände. Die Wanne 29 füllt sich selbst mit Reinigungsmittel 28 und Farbrückständen 27, die über die Düsenleisten 16; 17 bzw. über die Polygonwalze 13 zugeführt werden. Die Flüssigkeit in der Wanne 29 läuft dann selbständig über und wird über die Waschmittelabführung 19 wieder dem Reinigungskreislauf zugeführt.4 shows a further embodiment variant according to FIG. 2. Arranged under the polygon roller 13 and inside the housing 12 is a trough 29 filled with cleaning agent 28, which is connected at its bottom to a vibration generator 31 and into which the surface of the polygon roller 13 is immersed. The vibration generator 31 rests on vibration isolators 32 which are connected to the bottom of the housing 12. The vibration generator 31 works in the ultrasound range and removes any color residues still remaining on the polygon roller 13. The tub 29 fills itself with cleaning agent 28 and paint residues 27, which are applied via the nozzle strips 16; 17 or supplied via the polygon roller 13. The liquid in the tub 29 then overflows automatically and is returned to the cleaning circuit via the detergent discharge 19.
