Abstract

The different coloured ink are each supplied in a cartridge (4) which is loaded into a cylindrical holder (12). The holder has a pressure cap with seals (18) to seal the cartridge holding cylinder. A pneumatic piston (11) sits on top of the cartridge and is pressed onto the cartridge by compressed air admitted via a control valve (21) in the cover. The ink is dispensed through an exit duct (16) in the bottom of the dispenser. The outside of the holder is fitted with a profiled grip which is used to mount the holder into the printing machine. A typical mounting has the holder fitted on a rail to dispense ink over the length of a dosing roller.

Description

Die Erfindung betrifft eine Vorrichtung zur Versorgung eines Druckmaschinenfarbwerks mit Farbe.The invention relates to a device for supplying a printing press ink with ink.

Bei der Herstellung von farbigen Drucken kommt es vielfach vor, daß einzelne Farben in nur sehr kleiner Menge benötigt werden. Derartige Farben werden bisher in der Regel in Dosen bereitgehalten und manuell mittels einer Spachtel in den Farbkasten des Farbwerks eingebracht. Dies erweist sich als sehr umständlich und aufwendig.In the production of colored prints, it often happens that individual colors are only required in very small quantities. Up to now, such colors have generally been kept in cans and manually introduced into the ink fountain of the inking unit using a spatula. This proves to be very cumbersome and complex.

Es sind auch schon Farbkartuschen in Verwendung, die mittels eines geeigneten Auspreßaggregats ausgepreßt werden können. Die zur Verfügung stehenden Auspreßaggregate sind jedoch als Handhebelpressen ausgebildet, die nur unter hohem Kraftauwand bedienbar sind. Dies ist sehr ermüdend und kann dazu führen, daß die Kartuschen nicht vollständig entleert werden, was die Materialkosten erhöht. Außerdem ist es praktisch nicht möglich, derartige Anordnungen in ein Druckmaschinenfarbwerk zu integrieren.Color cartridges are already in use and can be pressed out by means of a suitable squeezing unit. However, the available squeezing units are designed as hand lever presses, which can only be operated with a high level of force. This is very tiring and can lead to the cartridges not being completely emptied, which increases the material costs. In addition, it is practically not possible to integrate such arrangements in a printing press inking unit.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, unter Vermeidung der Nachteile der bekannten Anordnungen eine Vorrichtung für den eingangs genannten Zweck zu schaffen, welche die Verwendung von Farbkartuschen ermöglicht und dennoch eine hohe Bedienungsfreundlichkeit gewährleistet.Proceeding from this, it is therefore the object of the present invention, while avoiding the disadvantages of the known arrangements to provide a device for the purpose mentioned, which enables the use of color cartridges and still ensures high ease of use.

Diese Aufgabe wird durch den Anspruch 1 gelöst.This object is solved by claim 1.

Die erfindungsgemäßen Maßnahmen ergeben in vorteilhafter Weise eine kompakte Anordnung, die ohne nennenswerten Kraftaufwand bedienbar ist. Gleichzeitig ist sichergestellt, daß die Farbkartuschen einfach gewechselt werden können. Die Verwendung von Druckluft zum Auspressen der Farbkartuschen ergibt aber nicht nur eine hohe Bedienungsfreundlichkeit, sondern ermöglicht auch eine einfache Integration der erfindungsgemäßen Anordnung in ein Farbwerk.The measures according to the invention advantageously result in a compact arrangement that can be operated without any significant effort. At the same time, it is ensured that the color cartridges can be easily replaced. The use of compressed air for pressing out the color cartridges not only results in a high level of user-friendliness, but also enables the arrangement according to the invention to be easily integrated into an inking unit.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. So kann das Auspreßaggregat ein Zylindergehäuse aufweisen, auf das die Deckelkappe aufschraubbar ist. Diese Maßnahmen ergeben eine hohe Festigkeit. Das Zylindergehäuse kann dabei die hierin einsetzbare Kartusche umfangsseitig stützen. Zweckmäßig ist das Zylindergehäuse daher im Bereich seines der Kartusche zugeordneten Aufnahmekanals mit nach innen vorspringenden Stützrippen versehen. Hierbei ergibt sich lediglich eine linienförmige Anlage an der Kartusche, was das Ein- und Ausführen einer Kartusche beim Kartuschenwechsel erleichtert.Advantageous refinements and appropriate further training of the higher-level measures are specified in the subclaims. For example, the squeezing unit can have a cylinder housing onto which the cover cap can be screwed. These measures result in high strength. The cylinder housing can support the cartridge that can be used here on the circumferential side. The cylinder housing is therefore expediently provided with inwardly projecting support ribs in the region of its receiving channel assigned to the cartridge. This only results in a linear contact with the cartridge, which makes it easier to insert and remove a cartridge when changing the cartridge.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, daß die Deckelkappe mit einem Anschlußstutzen für eine Druckluftleitung versehen ist. Dies ermöglicht in vorteilhafter Weise einen Anschluß an jede zur Verfügung stehende Druckluftquelle, beispielsweise ein Druckluftnetz mittels eines geeigneten Schlauchs.Another expedient measure can consist in that the cover cap is provided with a connecting piece for a compressed air line. This advantageously enables a connection to any available compressed air source, for example a compressed air network, using a suitable hose.

Vorteilhaft kann die Deckelkappe einen den Anschlußstutzen umfassenden Kragen aufweisen, auf dem ein Ventil zum Absperren des den Anschlußstutzen durchsetzenden Strömungswegs angeordnet ist. Der genannte Kragen ergibt eine hohe Stabilität.The cover cap can advantageously have a collar which surrounds the connection piece and on which a valve for blocking the flow path passing through the connection piece is arranged. The collar mentioned gives high stability.

In weiterer Fortbildung der übergeordneten Maßnahmen kann das Zylindergehäuse wenigstens einen umfangsseitig vorgesehenen Halter aufweisen. Dieser kann zweckmäßig als Griff und/oder als Anbauorgan ausgebildet sein, das einen Anbau an einen maschinenseitigen Träger, beispielsweise an einen auf einer Traverse verschiebbar aufgenommenen Schlitten, ermöglicht.In a further development of the higher-level measures, the cylinder housing can have at least one holder provided on the circumference. This can expediently be designed as a handle and / or as an add-on element which enables attachment to a machine-side support, for example to a slide which is displaceably received on a crossmember.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung entnehmbar.Further advantageous refinements and expedient further developments of the superordinate measures are specified in the remaining subclaims and can be found in the following description of the examples with reference to the drawing.

In the drawing described below:
Figure 1
2 shows a schematic view of an inking unit provided with a device according to the invention,
Figure 2
a section through the device according to the invention and
Figure 3
an external view of the device according to the invention.

Das der Figur 1 zugrunde liegende Farbwerk enthält einen zwischen einer Walze 1 und hiermit zusammenwirkenden Farbmessern 2 einstellbaren Farbspalt, dem ein Farbkasten 3 vorgeordnet ist. Durch die Walze 1 wird eine durch die Farbmesser 2 dosierbare Farbmenge abtransportiert. Zur Versorgung des Farbkastens 3 mit Farbe ist eine die Farbe enthaltene Kartusche 4 vorgesehen, die in ein oberhalb des Farbkastens 3 angeordnetes Auspreßaggregat 5 eingesetzt ist. Dieses ist hier an einem Schlitten 6 befestigt, der auf einer zur Walze 1 parallelen Traverse 7 verschiebbar im Farbwerksgestell aufgenommen ist, wodurch eine Verteilung der aus der Kartusche 4 ausgepreßten Farbe über die Länge der Walze 1 bzw. einer jeweils zu versorgenden Farbzone möglich ist.The inking unit on which FIG. 1 is based contains an ink gap which can be set between a roller 1 and ink knives 2 interacting therewith and to which an ink fountain 3 is arranged. A quantity of ink which can be metered by the ink knife 2 is removed by the roller 1. To supply the ink fountain 3 with ink, a cartridge 4 containing the ink is provided, which is inserted into an extrusion unit 5 arranged above the ink fountain 3. This is attached to a carriage 6, which on a Roller 1 parallel traverse 7 is slidably received in the inking unit frame, whereby a distribution of the ink squeezed out of the cartridge 4 over the length of the roller 1 or a respective ink zone to be supplied is possible.

Die Kartusche 4 enthält, wie am besten aus Figur 2 erkennbar ist, einen rohrförmigen, als Farbspeicher fungierenden Zylinder 8. Dieser ist vorne mit einer angesetzten Kappe 9 versehen, die einen Austragstutzen 10 aufweist, der mit einem abnehmbaren Steck-oder Schraubverschluß oder einfach mit einer abschneidbaren Spitze versehen sein kann. Der rückwärtige Verschluß des Zylinders 8 wird durch einen kolbenartig ausgebildeten und im Zylinder 8 angeordneten Boden 11 gebildet.The cartridge 4 contains, as can best be seen from FIG. 2, a tubular cylinder 8 that functions as an ink reservoir. This cylinder is provided at the front with an attached cap 9 which has a discharge nozzle 10 which can be fitted with a removable plug-in or screw closure or simply with can be provided with a tip that can be cut off. The rear closure of the cylinder 8 is formed by a piston-like base 11 arranged in the cylinder 8.

Das Auspreßaggregat 5 enthält ein Zylindergehäuse 12, in welches die Kartusche 4 einsetzbar ist. Das Zylindergehäuse 12, das als aus Kunststoff bestehender Spritzgußformling ausgebildet sein kann, ist hierzu mit einem der Kartusche 4 zugeordneten Aufnahmekanal 13 versehen. Die vordere Stirnwand des Zylindergehäuses 12 ist als Kartuschenanschlag 14 ausgebildet, der eine zentrale Öffnung aufweist, die so ausgebildet ist, daß nur der Ausbringstutzen 10 der Kartusche 4 in geöffnetem Zustand hindurchpaßt. Im dargestellten Beispiel ist die vordere Stirnwand des Zylindergehäuses 12 mit einem die zentrale Öffnung umfaßenden Kragen 15 versehen, der an seinem Ende einen äußeren Bund aufweist. Auf den Kragen 15 kann eine Gummitülle 16 aufgesteckt werden. Diese ist im dargestellten Beispiel als Winkeltülle ausgebildet, was eine Umlenkung des austretenden Farbstrangs ermöglicht. Dies kann bei horizontaler Anordnung der erfindungsgemäßen Vorrichtung von Vorteil sein.The squeezing unit 5 contains a cylinder housing 12 in which the cartridge 4 can be inserted. For this purpose, the cylinder housing 12, which can be designed as an injection molding made of plastic, is provided with a receiving channel 13 assigned to the cartridge 4. The front end wall of the cylinder housing 12 is designed as a cartridge stop 14 which has a central opening which is designed such that only the dispensing nozzle 10 of the cartridge 4 fits through in the open state. In the example shown, the front end wall of the cylinder housing 12 is provided with a collar 15 which surrounds the central opening and which has an outer collar at its end. A rubber grommet 16 can be attached to the collar 15. In the example shown, this is designed as an angle grommet, which allows the emerging color strand to be deflected. This can be advantageous when the device according to the invention is arranged horizontally.

Am hinteren Rand des Zylindergehäuses 12 ist dieses mit einem Gewinde versehen, auf das eine mit einem Gegengewinde versehene Deckelkappe 17 aufschraubbar ist. Die Deckelkappe 17, die ebenfalls als aus Kunststoff bestehender Spritzgußformling ausgebildet sein kann, besitzt eine hier durch einen umlaufenden Steg gebildete Nut, in die ein Dichtring 18 eingelegt ist. Dieser ist so angeordnet, daß er bei in Stellung gebrachter Deckelkappe 17 auf die hintere Stirnseite des Zylinders 8 der Kartusche 4 drückt und somit eine dichte Verbindung zwischen der Deckelkappe 17 und dem Zylinder 8 bewirkt.At the rear edge of the cylinder housing 12, this is provided with a thread onto which a cover cap 17 provided with a counter thread can be screwed. The lid cap 17, which is also made of plastic existing injection molding can be formed, has a groove formed here by a circumferential web, in which a sealing ring 18 is inserted. This is arranged such that it presses on the rear end face of the cylinder 8 of the cartridge 4 when the cover cap 17 is in position and thus causes a tight connection between the cover cap 17 and the cylinder 8.

Die Deckelkappe 17 ist rückwärtig mit einem Anschlußstutzen 19 versehen, der eine in den vom Dichtring 18 nach außen abgedichteten Raum mündende Bohrung enthält und auf den ein zu einer Druckluftquelle führender Druckluftschlauch aufsteckbar ist. Als Druckluftquelle kann das praktisch in jedem Druckereibetrieb vorhandene Druckluftnetz Verwendung finden. Der Anschlußstutzen 19 ist von einem Kragen 20 der Deckelkappe 17 umfaßt, auf dem ein Ventil 21 aufgenommen ist, durch das der den Anschlußstutzen 19 durchsetzende Strömungsweg auf- und absteuerbar ist. Das Ventil 21 ist mit einem Schaltknopf 22 für manuelle Betätigung versehen.The cover cap 17 is provided at the rear with a connecting piece 19 which contains a bore opening into the space sealed off from the sealing ring 18 and onto which a compressed air hose leading to a compressed air source can be plugged. The compressed air network available in practically every printing company can be used as a compressed air source. The connecting piece 19 is surrounded by a collar 20 of the cover cap 17, on which a valve 21 is received, through which the flow path passing through the connecting piece 19 can be opened and closed. The valve 21 is provided with a switch button 22 for manual actuation.

Durch Öffnen des Ventils wird der hinterhalb des kolbenförmigen Bodens 11 sich befindende, mittels des Dichtrings 18 nach außen abgedichtete Raum mit Druckluft beaufschlagt. Diese bewirkt eine Verschiebung des Kolbens nach vorne, das heißt in Auspreßrichtung, wodurch eine entsprechende Farbmenge über den Austragstutzen 10 ausgepreßt wird. Der Auspreßdruck wirkt nur auf die Kartusche 4 und die dichtend hiermit zusammenwirkende Deckelkappe 17. Das Zylindergehäuse 12 wird hiervon nicht beanssprucht. Dieses kann daher den kartuschenseitigen Zylinder 8 umfangsseitig stützen. Hierzu kann das Zylindergehäuse 12 im Bereich seines Innenumfangs mit nach innen vorspringenden, an den Enden zweckmäßig abgeschrägten Stützrippen 23 versehen sein. An diesen liegt der Zylinder 8 linienförmig an, was den Ein- und Ausfahrvorgang erleichtet.By opening the valve, the space located behind the piston-shaped base 11 and sealed to the outside by means of the sealing ring 18 is acted upon by compressed air. This causes the piston to move forward, that is, in the squeezing direction, whereby a corresponding amount of paint is squeezed out through the discharge nozzle 10. The squeezing pressure acts only on the cartridge 4 and the cover cap 17, which cooperates in a sealing manner therewith. The cylinder housing 12 is not subjected to this. This can therefore support the cartridge-side cylinder 8 on the circumferential side. For this purpose, the cylinder housing 12 can be provided in the region of its inner circumference with inwardly projecting support ribs 23 which are advantageously bevelled at the ends. The cylinder 8 is in linear contact with this, which facilitates the retraction and extension process.

Das Zylindergehäuse 12 ist, wie Figur 3 zeigt, außen mit zwei einander gegenüberliegenden, bügelförmigen Haltern 24 versehen. Diese können als Handgriff und/oder als Anbauteil dienen, mit dem eine Befestigung an einem Träger möglich ist. Bei dem der Figur 1 zugrunde liegenden Beispiel ist das Zylindergehäuse 12, wie oben schon angedeutet wurde, über einen der Halter 24 am Schlitten 6 befestigt. Der andere Halter 24 kann als Griff zum manuellen Verschieben der vorliegenden Anordnung entlang der Traverse 7 benutzt werden, wodurch eine Verteilung des von der Kartusche abgegebenen Farbstrangs auf eine größere Länge möglich ist. Bei der der Figur 1 zugrunde liegenden Vorrichtung ist die Anordnung so gewählt, daß der aus der Kartusche 4 ausgepreßte Farbstrang direkt auf den Umfang der Walze 1 gelangt und so durch diese zuverlässig zum Farbspalt zwischen der Walze 1 und dem Farbmesser 2 transportiert wird, was einen besonders sparsamen Farbverbrauch gewährleistet.As shown in FIG. 3, the cylinder housing 12 is provided on the outside with two bow-shaped holders 24 lying opposite one another. These can serve as a handle and / or as an attachment, with which attachment to a carrier is possible. In the example on which FIG. 1 is based, the cylinder housing 12 is, as has already been indicated above, fastened to the carriage 6 via one of the holders 24. The other holder 24 can be used as a handle for manually moving the present arrangement along the crossmember 7, as a result of which it is possible to distribute the ink strand discharged from the cartridge over a greater length. In the device on which FIG. 1 is based, the arrangement is selected such that the ink strand squeezed out of the cartridge 4 reaches the circumference of the roller 1 and is thus reliably transported to the ink gap between the roller 1 and the ink knife 2, which is a problem particularly economical ink consumption guaranteed.
