Description

Die Erfindung betrifft eine Vorrichtung zur Versorgung einer Einrichtung zur Aufnahme von hochviskosen Medien mit einem solchen, insbesondere zur Versorgung eines Farbspeichers einer Druckmaschine mit Druckfarbe, mit einem mit dem hochviskosen Medium beaufschlagbaren Befüllkanal, der wenigstens einen, der Aufnahmeeinrichtung zugeordneten Auslaß aufweist.The invention relates to a device for supplying a Device for taking up highly viscous media with a such, in particular for supplying a color memory a printing machine with printing ink, with one with the highly viscous Filling channel that can be acted on, at least an outlet assigned to the receiving device.

Eine Vorrichtung zur Versorgung eines Farbspeichers einer Druckmaschine mit Druckfarbe eingangs erwähnter Art ist aus der DE 199 12 881 C2 bekannt. Bei dieser bekannten Anordnung ist ein über den Farbkasten einer Druckmaschine hinweggehender, an eine Farbzuführleitung angeschlossener Befüllkanal vorgesehen, der mit mehreren, über seine Länge verteilten, als Querbohrungen ausgebildeten, unten offenen Auslässen versehen ist. In der Farbzuführleitung ist ein Absperrventil angeordnet, durch das die Abgabe von Farbe an den Farbkasten kontrollierbar ist. Durch Schließen des Absperrventils soll die Farbzufuhr zum Farbkasten unterbrochen werden. Die Erfahrung zeigt jedoch, dass hinter dem Absperrventil sich befindende Restfarbe nachtropfen kann, wobei die Farbe in der Regel dünne, leicht antrocknende Farbfäden zieht oder ganz austrocknet. Dies beeinträchtigt die Druckqualität und die Funktionssicherheit und ist daher unerwünscht. A device for supplying a color memory Printing machine with printing ink of the type mentioned at the beginning is out known from DE 199 12 881 C2. In this known arrangement is an over the ink fountain of a printing press, filling channel connected to a paint supply line provided with several, distributed over its length, provided as cross holes, open at the bottom outlets is. A shut-off valve is arranged in the paint supply line, by delivering paint to the paint box is controllable. By closing the shut-off valve the ink supply to the ink fountain is interrupted. The experience shows, however, that there is behind the shut-off valve Residual paint can drip, the color in the Usually thin, slightly drying colored threads pull or completely dry out. This affects the print quality and the Reliability and is therefore undesirable.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art unter Vermeidung der geschilderten Nachteile mit einfachen und kostengünstigen Mitteln so zu verbessern, dass ein Nachtropfen weitestgehend vermieden wird.Based on this, it is therefore the task of the present one Invention, a device of the type mentioned avoiding the disadvantages described with simple and inexpensive Means to improve so that dripping as far as possible is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jedem Auslaß ein endseitiges Abdeckelement zugeordnet ist, das wenigstens eine Auslaßöffnung aufweist, die durch wenigstens eine zugeordnete, unter Druck elastisch ausweichende Zunge verschließbar ist.This object is achieved in that everyone Outlet is assigned an end cover element, which at least has an outlet opening through at least an associated tongue that elastically escapes under pressure is lockable.

Mit diesen Maßnahmen werden die eingangs geschilderten Nachteile vollständig vermieden. Die Zunge öffnet selbsttätig, sobald das zugeführte Medium einen vorgegebenen Druck erreicht. Sobald dieser Druck unter die elastische Rückstellkraft der Zunge abfällt, geht diese aufgrund ihrer Federwirkung selbsttätig in ihre Ausgangslage zurück, in der die zugeordnete Auslaßöffnung geschlossen gehalten wird. Versuche haben gezeigt, dass der Farbfaden hier nach kurzer Zeit abreißt und die stromaufwärts des Abdeckelements vorhandene Restfarbe weder austropfen noch austrocknen kann. Die erfindungsgemäßen Maßnahmen ergeben somit eine hohe Funktionssicherheit und gewährleisten gleichzeitig eine hohe Produktionsqualität.These measures are the ones described at the beginning Completely avoided disadvantages. The tongue opens automatically as soon as the supplied medium has a predetermined pressure reached. As soon as this pressure falls below the elastic restoring force the tongue falls off, this goes due to its spring action automatically return to their starting position in which the assigned Exhaust port is kept closed. tries have shown that the color thread here after a short time tears off and the existing upstream of the cover Residual paint can neither drip nor dry out. The invention Measures thus result in a high level of functional reliability and at the same time ensure high production quality.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. So kann das Abdeckelement vorteilhaft als aus gummielastischem Material bestehende Scheibe ausgebildet sein, die mittels einer Überwurfmutter am unteren Ende eines Auslassstutzens angebracht und mit wenigstens eine Zunge begrenzenden Schlitzen versehen ist. Auf diese Weise ergibt sich eine höchst einfache und kompakte Ausführung, die sowohl in der Herstellung als auch in der Montage kostengünstig ist. Ein weiterer Vorteil ist auch in der einfachen Nachrüstbarkeit zu sehen.Advantageous refinements and practical training the overriding measures are specified in the subclaims. For example, the cover element can advantageously be made of rubber-elastic Material existing disc to be formed by means of a union nut at the lower end of an outlet nozzle attached and delimiting with at least one tongue Slits is provided. In this way there is a extremely simple and compact design, both in the Manufacturing and assembly is inexpensive. On Another advantage is the ease of retrofitting see.

Zweckmäßig sind die zur Bildung der Zunge bzw. Zungen vorgesehenen Schlitze als materialausnehmungslose Schnitte ausgebildet. Hierdurch ist sichergestellt, dass die Seitenflanken jeder Zunge auf der ganzen Dicke der das Abdeckelement bildenden Scheibe in dichtende Anlage an einer zugeordneten Gegenfläche kommen, was eine zuverlässige Abdichtung ergibt und gleichzeitig zu einer erwünschten Selbstreinigung der genannten Flächen führt.The ones intended to form the tongue or tongues are expedient Slits formed as cuts without material exceptions. This ensures that the side flanks each tongue over the entire thickness of the cover element Washer in sealing system on an assigned Mating surface come, which results in a reliable seal and at the same time to a desired self-cleaning of the above Surfaces leads.

In weiterer Fortbildung der übergeordneten Maßnahmen kann das Abdeckelement mehrere, aneinander anschließende, ringförmig angeordnete, dreieckförmig zugeschnittene Zungen aufweisen. Auf diese Weise lässt sich ein vergleichsweise großer Querschnitt der zugeordneten Auslaßöffnung erreichen.In further training of the overarching measures, this can Cover element several, adjoining, ring-shaped arranged, triangular cut tongues. In this way, a comparatively large cross section can be created reach the assigned outlet opening.

Eine besonders bevorzugte Ausführung besteht darin, dass bei einem aus Polyurethan bestehenden, scheibenförmigen Abdeckelement mit einem Durchmesser von 22 mm und einer Dicke von 2 mm die Länge der Seitenkanten der Zungen 5 mm beträgt. Mit einer derartigen Anordnung lassen sich, wie Versuche gezeigt haben, bei Vorrichtungen zur Farbversorgung von Druckmaschinen ausgezeichnete Ergebnisse erreichen.A particularly preferred embodiment is that at a disc-shaped cover element made of polyurethane with a diameter of 22 mm and a thickness of 2 mm the length of the side edges of the tongues is 5 mm. With Such an arrangement can, as experiments have shown have in devices for ink supply of printing machines achieve excellent results.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous refinements and practical training the overriding measures are in the rest Subclaims specified and from the following Example description can be taken from the drawing.

Die in Figur 1 angedeutete Druckmaschine 1 enthält eine Duktorwalze 2, der ein durch an der Duktorwalze 2 streifende Farbmesser 3 begrenzter Farbkasten 4 zugeordnet ist. Die Duktorwalze 2 wirkt mit nicht näher dargestellten, weiterführenden Farbwerkswalzen zusammen. Dem Farbkasten 4 wird Farbe zugeführt. Dabei handelt es sich um ein honigzähes, hochviskoses Medium.The printing press 1 indicated in FIG. 1 contains one Duktorwalze 2, the one by grazing on the Duktorwalze 2 Color knife 3 is assigned limited color box 4. The Ductor roller 2 acts with further, not shown Inking rollers together. The color box 4 becomes color fed. It is a honey-viscous, highly viscous Medium.

Die hierzu vorgesehene Versorgungseinrichtung enthält eine in die Druckmaschine eingebaute Befülleinheit 5, die ein über eine Farbzuführleitung 6 mit Farbe beaufschlagbares, über den Farbkasten 4 hinweggehendes Verteilerrohr 7 und ein diesem vorgeordnetes, in der Farbzuführleitung 6 angeordnetes Absperrventil 8 aufweist. Das Verteilerrohr 7 ist mit mehreren, über seiner Länge verteilten Auslaßstutzen 9 versehen.The supply device provided for this contains an in the printing press built-in filling unit 5, which a a paint supply line 6 to which paint can be applied, via which Paint box 4 passing manifold 7 and this one upstream, arranged in the ink supply line 6 Shutoff valve 8 has. The distributor pipe 7 is provided with several provided over its length outlet connector 9.

Das Verteilerrohr 7 kann, wie am besten aus Figur 2 ersichtlich ist, als stirnseitig verschlossene Hohlschiene ausgebildet sein, deren Innenraum über einen Nippel 10 an die Farbzuführleitung 6 anschließbar ist und die im Bereich ihrer Unterseite mit den farbkastenseitig vorspringenden, über seine Länge verteilten Auslaßstutzen 9 versehen ist. Diese enthalten jeweils eine mit dem Innenraum des Verteilerrohrs 7 kommunizierende Bohrung. Das Absperrventil 8 kann zusammen mit der zugeordneten Betätigungseinrichtung in die das Verteilerrohr 7 bildende Hohlschiene integriert sein.The distributor pipe 7 can, as best seen in Figure 2 is designed as a hollow rail closed at the end be, the interior of which via a nipple 10 to the paint feed line 6 is connectable and in the area of its bottom with the color box projecting over his Length distributed outlet connector 9 is provided. These contain one each communicating with the interior of the distributor pipe 7 Drilling. The shut-off valve 8 can be used together with the associated actuator in the manifold 7 forming hollow rail can be integrated.

Die Farbzuführleitung 6 geht von einer Farbquelle ab, die hier aus einem Farbgebinde 11 und einer hieran angeschlossenen Pumpe 12 besteht, so dass die Farbe unter Druck zur Verfügung gestellt wird. In der Regel ist für sämtliche Farbkästen der Druckmaschine 1 eine Farbquelle vorgesehen. Die Pumpe 12 kann daher immer im Betrieb sein. Es wäre aber auch denkbar, die Pumpe 12 gemeinsam mit dem Absperrventil 8 zu aktivieren bzw. zu passivieren.The ink supply line 6 starts from an ink source that here from a paint container 11 and one connected to it Pump 12 is there so that the paint under pressure to Is made available. Usually is for all paint boxes the printing press 1 a color source is provided. The Pump 12 can therefore always be in operation. But it would be too conceivable, the pump 12 together with the shut-off valve 8 activate or passivate.

Zur Betätigung des Absperrventils 8 kann ein dem Farbkasten 4 zugeordneter Füllstandsdetektor vorgesehen sein. Sobald der Füllstand im Farbkasten 4 unter ein vorgegebenes Maß absinkt, wird die dem Absperrventil 8 zugeordnete Betätigungseinrichtung vom Füllstandsdetektor so angesteuert, dass das Absperrventil 8 geöffnet und dementsprechend der Innenraum des Verteilerrohrs 7 mit unter Druck anstehender Farbe beaufschlagt wird, die über die Auslaßstutzen 9 austreten kann. Sobald der Füllstand im Farbkasten 4 einen vorgegebenen Höchststand erreicht hat, wird das Absperrventil 8 in die Schließstellung gebracht.To activate the shut-off valve 8, the ink fountain 4 assigned fill level detector may be provided. Once the Fill level in the ink fountain 4 drops below a predetermined level, becomes the actuating device assigned to the shut-off valve 8 controlled by the level detector so that the shut-off valve 8 opened and accordingly the interior of the manifold 7 pressurized paint is that can exit through the outlet 9. Once the Fill level in the ink fountain 4 reaches a predetermined maximum level has the shut-off valve 8 in the closed position brought.

Um dabei ein Nachtropfen von Farbe zu unterbinden und einen zuverlässigen Verschluss der Auslaßstutzen 9 zu gewährleisten, sind die Auslaßstutzen 9 jeweils, wie aus den Figuren 3 und 4 entnehmbar ist, an ihrem unteren Ende mit einem Abdeckelement 13 versehen, das als unter Druck öffnendes und bei nachlassendem Druck selbsttätig schließendes Organ ausgebildet ist. Das Abdeckelement 13 ist als aus elastischem Material, vorzugsweise gummielastischem Material, wie gummielastischem Kunststoff, beispielsweise in der Form von Polyurethan, bestehende Scheibe ausgebildet, die mittels einer zugeordneten Überwurfmutter 14 am unteren Ende des zugeordneten Auslaßstutzens 9 angebracht ist. Die Überwurfmutter 14 bestitzt einen Freistich, in den das zugeordnete, scheibenförmige Abdeckelement 13 eingelegt ist.To prevent dripping of paint and one reliable closure of the outlet nozzle 9 too ensure the outlet 9 are each, as from the Figures 3 and 4 can be removed with at its lower end provided a cover member 13 which opens as a pressure and automatically closes when the pressure drops Organ is trained. The cover member 13 is made of elastic material, preferably rubber-elastic material, like rubber-elastic plastic, for example in shape of polyurethane, existing disc formed by means of an associated union nut 14 at the lower end of assigned outlet 9 is attached. The cap nut 14 has an undercut into which the assigned disc-shaped cover element 13 is inserted.

Im dargestellten Beispiel sind die Auslaßstutzen 9 mehrteilig ausgebildet, wobei ein oberes, mit dem Verteilerrohr 4 verschraubtes Teilstück und ein unteres, die Überwurfmutter 9 tragendes Teilstück sowie ein Mittelstück vorgesehen sind, das ein in den Figuren 3 und 4 nicht näher dargestelltes Drosselorgan enthalten kann.In the example shown, the outlet ports 9 are in several parts formed, an upper, with the manifold 4th screwed section and a lower one, the union nut 9 load-bearing section and a center piece are provided, the one not shown in Figures 3 and 4 Restrictor can contain.

Die das Abdeckelement 13 bildende Scheibe ist, wie am besten aus Figur 5 erkennbar ist, mit durch in der Scheibenmitte sich kreuzende Schlitze 15 gebildeten, ringförmig angeordneten, dreieckförmigen Zungen 16 versehen, die bei drucklosem Innenraum des Verteilerrohrs 7 koplanar ausgerichtet sind und im Bereich der Schlitze 15 dichtend aneinander anliegen und die, wie in Figur 4 angedeutet ist, unter Druck elastisch nach unten ausweichen können, so dass sich eine in Figur 4 angedeutete Auslaßöffnung 17 ergibt, durch die ein Farbstrang 18 austreten kann. Sobald der Druck im Innenraum des Verteilerrohrs 7 wegfällt, was beim Schließen des Absperrventils 8 eintritt, federn die Zungen 6 von der der Figur 4 zugrunde liegenden Öffnungsstellung in die der Figur 3 zugrunde liegende Schließstellung zurück, wodurch die Auslaßöffnung 17 geschlossen wird und einem Nachtropfen bzw. Austrocknen von Restfarbe wirksam vorgebeugt ist.The disk forming the cover member 13 is as best can be seen from Figure 5, with through in the center of the pane intersecting slots 15 formed, arranged in a ring, triangular tongues 16 provided, when depressurized Interior of the manifold 7 are coplanar and close to each other in the area of the slots 15 and which, as indicated in Figure 4, elastic under pressure can dodge downwards, so that one in FIG indicated outlet opening 17 through which a color strand 18 can emerge. As soon as the pressure inside the manifold 7 is omitted, what happens when the shut-off valve 8 is closed occurs, the tongues 6 spring from that of FIG. 4 lying open position in the figure 3 based lying closed position, whereby the outlet opening 17th is closed and dripping or drying out of Residual color is effectively prevented.

Im dargestellten Beispiel beträgt der in Figur 5 angedeutete Winkel α zwischen den Schlitzen 15 60°, so dass sich über dem ganzen Umfang 6 aneinander anschließende, ringförmig angeordnete Zungen 16 ergeben. Die die Zungen 16 seitlich begrenzenden Schlitze 15 sind zweckmäßig als materialausnehmungslose Schnitte ausgebildet, so dass die Zungen 16 in der der Figur 3 zugrunde liegenden Schließstellung im Bereich der ganzen Dicke des Abdeckelements 13 in gegenseitige, dichtende Anlage kommen. Die in gegenseitige dichtende Anlage kommenden Seitenflanken streifen sich dabei gegenseitig ab, was eine Selbstreinigung ergibt.In the example shown, the one indicated in FIG. 5 is Angle α between the slots 15 60 °, so that over the whole circumference 6 adjoining, arranged in a ring Tongues 16 result. The laterally delimiting the tongues 16 Slots 15 are useful as material-free Incisions formed so that the tongues 16 in the figure 3 underlying closed position in the area of the whole Thickness of the cover element 13 in mutual, sealing contact come. The coming into mutual sealing facility Side flanks brush each other off, which is one Self-cleaning results.

Im dargestellten Beispiel besitzt das scheibenförmige Abdeckelement 13 einen Durchmesser d von 22 mm und eine Dicke von 2 mm, also weniger als ein Zehntel des Durchmessers. Die Länge der in der Mitte sich kreuzenden Schlitze 15 beträgt 10 mm, so dass sich eine Länge 1 der Seitenflanken der Zungen 16 von 5 mm, also weniger als ein Vierteil des Durchmessers d ergibt. Als Ausgangsmaterial zur Herstellung der scheibenförmigen Abdeckelemente 13 kann eine Polyurethan-Folie mit der gewünschten Dicke von 2 mm Verwendung finden.In the example shown, the disc-shaped cover element 13 a diameter d of 22 mm and a thickness of 2 mm, i.e. less than a tenth of the diameter. The The length of the intersecting slots 15 in the middle is 10 mm, so that a length 1 of the side flanks of the tongues 16 of 5 mm, that is less than a quarter of the diameter d results. As the starting material for the production of the disc-shaped Cover elements 13 can be a polyurethane film with the desired thickness of 2 mm can be used.

Vorstehend ist ein bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert, ohne dass jedoch hiermit eine Beschränkung verbunden sein soll. So wäre es anstelle durch Schnitte angeformter Zungen selbstverständlich auch denkbar, angesetzte Zungen vorzusehen und/oder andere Materialien zu verwenden.Above is a preferred embodiment of the invention explained in more detail, but without any limitation should be connected. So it would be instead of cuts molded tongues of course also conceivable, attached Provide tongues and / or use other materials.
