Description

Die vorliegende Erfindung betrifft eine Färbeeinrichtung für Tampondruckmaschinen zum Auftragen von Farbe auf ein Klischee. Bei bisher bekannten Vorrichtungen wird Farbe über den geöffneten Boden eines Hohlkörpers, insbesondere eines Napfes od. dgl., dem Klischee zugeführt. Die Wände des Hohlkörpers sind als Rakel ausgebildet. Sofern der Hohlkörper nicht fest auf dem Klischee aufliegt, verschmiert dieses und man erhält nur völlig unzureichende und verwischte Abdrucke. Um ein dichtes Aufliegen des Hohlkörpers auf dem Klischee zu gewährleisten, wird die Anpresskraft der Färbeeinrichtung auf das Klischee erfindungsgemäß dadurch erreicht bzw. verstärkt, daß im Hohlkörper ein oder mehrere Magnete angeordnet sind.The present invention relates to a dyeing device for pad printing machines for applying ink to a cliché. In previously known devices, ink is supplied to the cliché via the open bottom of a hollow body, in particular a bowl or the like. The walls of the hollow body are designed as a doctor blade. If the hollow body does not lie firmly on the cliché, it smears and you get only completely inadequate and blurred imprints. To ensure that the hollow body fits tightly To ensure on the plate, the pressing force of the dyeing device on the plate is achieved or increased according to the invention in that one or more magnets are arranged in the hollow body.

Zweckmäßigerweise sind die Magnete in taschenförmigen Vertiefungen des Hohlkörpers befestigt, die sie vor dem Farbmedium schützen. Lösbare Befestigungen im Hohlkörper ermöglichen ein Auswechseln der Magnete.The magnets are expediently fastened in pocket-shaped depressions in the hollow body, which protect them from the color medium. Detachable fastenings in the hollow body allow the magnets to be replaced.

Bei einer besonders zweckmäßigen Ausführungsform der Erfindung ist der Hohlkörper quaderförmig und die Innenkammer im Querschnitt als längliches Rechteck ausgebildet. Vorzugsweise sind die taschenförmigen Vertiefungen für die Magnete an den Stirnseiten des quaderförmigen Hohlkörpers angeordnet, um sie vor jeder Berührung mit der Farbe zu schützen.In a particularly expedient embodiment of the invention, the hollow body is cuboid and the inner chamber is designed in cross section as an elongated rectangle. The pocket-shaped depressions for the magnets are preferably arranged on the end faces of the cuboid hollow body in order to protect them from any contact with the paint.

Beim Überstreichen des Klischees mit dem Farbnapf wird eine gewisse Farbmenge vom Napf wieder aufgenommen. Eine abgerakelte Farbrestmenge staut sich an der Außenwand des Napfes auf. Bei Störungen oder Arbeitspausen besteht die Gefahr, daß insbesondere an den Wänden des Napfes die Farbe antrocknet. Es ist dann oft erforderlich, vor Wiederinbetriebnahme der Druckmaschine angetrocknete Farbe zu entfernen.When painting over the cliché with the paint bowl, a certain amount of paint is taken up again by the bowl. A scraped amount of paint residue builds up on the outside wall of the bowl. In the event of malfunctions or breaks, there is a risk that the paint will dry, particularly on the walls of the bowl. It is then often necessary to remove dried ink before restarting the press.

Um diese aufgezeigten Schwierigkeiten zu beseitigen und einen Hohlkörper so auszubilden, daß Farbverfestigungen nicht mehr auftreten, weist der Hohlkörper mindestens zwei nach unten offene, in sich geschlossene Kammern auf, von denen wenigstens eine mit einer Farbzu- und abführung versehen ist. Durch die Aufteilung des Hohlkörpers in zwei Kammern besteht die Möglichkeit, in der Kammer, die sowohl eine Farbzuführung als auch eine -abführung aufweist, einen Farbaustausch stattfinden zu lassen. Hierdurch wird ein Verfestigungsprozeß im Kammerbereich verhindert.To eliminate these difficulties and one To design hollow bodies so that color hardening no longer occurs, the hollow body has at least two downwardly open, self-contained chambers, at least one of which is provided with a paint feed and discharge. By dividing the hollow body into two chambers, there is the possibility of allowing a color exchange to take place in the chamber, which has both a paint feed and a paint drain. This prevents a solidification process in the chamber area.

Das Kammersystem ist zweckmäßigerweise so angelegt, daß eine Innenkammer innerhalb einer von den Wänden des Hohlkörpers gebildeten Außenkammer angeordnet ist. Diese Anordnung ermöglicht eine kompakte Bauweise des Hohlkörpers.The chamber system is expediently designed such that an inner chamber is arranged within an outer chamber formed by the walls of the hollow body. This arrangement enables a compact design of the hollow body.

Die Innenkammer weist dabei vorteilhaft die Farbzu- und - abführung auf, wobei die Außenkammer wenigstens eine Farbabführung besitzt. Die Innenkammer färbt das Klischee ein und nimmt einen Teil abgerakelter Farbe wieder auf. Eine verbleibende Restfarbmenge auf dem Klischee wird durch die Außenkammer aufgenommen.The inner chamber advantageously has the color supply and removal, the outer chamber having at least one color discharge. The inner chamber dyes the cliché and takes up part of the doctored paint. Any remaining amount of ink left on the plate is taken up by the outer chamber.

Die Anordnung einer Farbabführung an der Außenkammer ermöglicht es, auch diese Restfarbmenge abzuleiten, wodurch ein sparsamer Verbrauch der Druckfarbe erreicht wird. Nach einem weiteren Merkmal der Erfindung sind die quer zur Bewegungsrichtung liegenden Kammerwandungen als Rakel ausgebildet. Dadurch ergibt sich eine doppelte Anzahl von Rakelwerkzeugen und infolgedessen auch eine sauberere Bearbeitung des Klischees.The arrangement of an ink discharge on the outer chamber makes it possible to derive this residual ink quantity, as a result of which the ink is used economically. According to a further feature of the invention, the chamber walls lying transversely to the direction of movement are designed as squeegees. This results in a double number of squeegee tools and consequently also a cleaner processing of the cliché.

Der Farbaustausch läßt sich vorzugsweise dadurch erreichen, daß die Farbzu- und -abführungen der Kammern mit einem Farbvorratsbehälter mit Umwälzpumpe verbunden sind. Die Umwälzpumpe bewirkt einen ständigen Umlauf der Farbe zwischen den Kammern und dem Farbvorratsbehälter, so daß ein Antrocknen verhindert wird. Zur Erlangung einer gleichbleibenden Farbkonsistenz ist vorzugsweise der Farbvorratsbehälter mit einem Behälter für ein Farblösungsmittel verbunden und weist eine Mischvorrichtung auf. Dies hat den Vorteil, daß ein ständiger Aufbereitungsprozeß im Farbvorratsbehälter stattfindet. Zweckmäßig ist der Behälter für Farblösungsmittel im Farbvorratsbehälter selbst angeordnet und durch eine Wandung gegenüber dem für die Farbe vorgesehenen Teil im Farbvorratsbehälter getrennt. Eine Trennung des Farbvorratsbehälters in zwei Bereiche erspart zusätzlichen Behälter mit Leitungen für das Farblösungsmittel. Vorteilhaft weist der Behälter für Lösungsmittel einen ringartigen Boden auf, auf dem ein Hohlzylinder als Innenwandung angeordnet ist, wobei die Außenwandung des Lösungsmittelbehälters der Farbvorratsbehälter selbst ist. Die Gestaltung des Behälters für das Farblösungsmittel ermöglicht den Lösungsdämpfen, sich im Farbbereich des Farbvorratsbehälters niederzuschlagen. Der im Zentrum angeordnete Hohlzylinder erlaubt weiterhin, eine Welle od. dgl. durchzuführen, um die Mischvorrichtung und die Umwälzpumpe anzutreiben.The ink exchange can preferably be achieved in that the ink inlets and outlets of the chambers are connected to an ink reservoir with a circulation pump. The circulation pump causes the paint to circulate continuously between the chambers and the ink reservoir so that it does not dry out. In order to achieve a constant color consistency, the ink reservoir is preferably connected to a container for a color solvent and has a mixing device. This has the advantage that a constant preparation process takes place in the ink reservoir. The container for color solvents is expediently arranged in the ink supply container itself and separated by a wall opposite the part intended for the color in the ink supply container. A separation of the ink reservoir into two areas saves additional containers with lines for the color solvent. The container for solvents advantageously has a ring-shaped base on which a hollow cylinder is arranged as the inner wall, the outer wall of the solvent container being the ink reservoir itself. The design of the container for the color solvent enables the solution vapors to be deposited in the color range of the ink reservoir. The hollow cylinder arranged in the center further allows a shaft or the like to be carried out in order to drive the mixing device and the circulation pump.

Vorzugsweise ist die Mischvorrichtung als propellerartiges Rührwerk ausgebildet und wird über einen außerhalb des Farbvorratsbehälters angebrachten Motor angetrieben. Das Rührwerk durchmischt die Lösungsdämpfe mit den Farbmedium und hält außerdem die Farbe in Bewegung. Nach einer besonders zweckmäßigen Art der Erfindung ist die Umwälzpumpe des Farbvorratsbehälters mit dem Antrieb der Mischvorrichtung verbunden. Die im Rührwerksbereich aufbereitete Farbe wird durch das Rührwerk in den Pumpbereich gedrückt. Dadurch wird der darunterliegende Pumpbereich ständig mit frischaufbereiteter Farbe gespeist. Die Umwälzpumpe selbst versorgt die Kammern mit dem frischen Farbmedium. Durch die Verbindung von Rührwerk und Umwälzpumpe mit einer Welle kann ein gemeinsamer Motor verwendet werden.The mixing device is preferably a propeller-type agitator formed and is driven by a motor mounted outside the ink reservoir. The agitator mixes the solution vapors with the color medium and also keeps the color in motion. According to a particularly expedient type of the invention, the circulation pump of the ink reservoir is connected to the drive of the mixing device. The color prepared in the agitator area is pressed into the pump area by the agitator. As a result, the pump area underneath is constantly fed with freshly prepared paint. The circulation pump itself supplies the chambers with the fresh paint medium. By connecting the agitator and the circulation pump to a shaft, a common motor can be used.

Vorzugsweise kann die Antrocknung der Farbe im Innenraum des Hohlkörpers zusätzlich noch dadurch verhindert werden, daß im Hohlkörper ein Rührwerk drehbar angetrieben gelagert ist. Durch die Rotation desselben wird die Farbe fortlaufend umgewälzt, wodurch ein Antrocknen weitgehend verhindert wird.Preferably, the drying of the paint in the interior of the hollow body can also be prevented in that a stirrer is rotatably driven in the hollow body. The color is continuously circulated by the rotation thereof, which largely prevents drying.

Vorzugsweise ist das Rührwerk auf einer durch den Hohlkörperdeckel nach außen geführten und dort mit einem Antrieb verbundenen Welle angeordnet. Damit bleibt der Antrieb von Farbe frei und es wird ein Verkleben desselben verhindert. Nach einem weiteren Merkmal der Erfindung ist der Antrieb als Klinkengetriebe ausgebildet, wobei ein Rastrad mit der Welle verbunden ist und die Klinken auf einem in Verschieberichtung von Hohlkörper bzw. Klischee verschiebbaren Schieber angeordnet sind. Dabei ist der Schieber zweckmäßig mit dem Klischee zur gegenläufigen Verschiebbarkeit verbunden. Vor allem kann der Schieber durch einen pneumatischen Hubzylinder angetrieben werden, welcher seinerseits vom Klischee gesteuert wird.The agitator is preferably arranged on a shaft which is guided outwards through the hollow body cover and is connected there with a drive. This keeps the drive free of paint and prevents it from sticking. According to a further feature of the invention, the drive is designed as a ratchet mechanism, a ratchet wheel being connected to the shaft and the ratchets on a hollow body or cliché in the direction of displacement slidable slide are arranged. The slide is expediently connected to the cliché for opposing displacement. Above all, the slide can be driven by a pneumatic lifting cylinder, which in turn is controlled by the cliché.

Um den Abstand zwischen dem Rührwerk und dem Klischee ändern zu können, weist die Welle nach einem weiteren Merkmal der Erfindung einen Gewindeteil auf, auf welchem eine sich außen am Hohlkörper abstützende Verstellmutter angeordnet ist. Durch Verdrehen der Verstellmutter wird die Welle nach oben bzw. nach unten verschoben, wobei zweckmäßigerweise ein Endanschlag vorgesehen ist, damit das Rührwerk einen Mindestabstand vom Klischee einhält, um ein Verschmieren desselben zu verhindern.In order to be able to change the distance between the agitator and the cliché, according to a further feature of the invention, the shaft has a threaded part on which an adjusting nut which is supported on the outside of the hollow body is arranged. By turning the adjusting nut, the shaft is moved upwards or downwards, an end stop expediently being provided so that the agitator maintains a minimum distance from the cliché in order to prevent the same from smearing.

Bei Verwendung eines Hohlkörpers mit Rührwerk werden zweckmäßig die Magnete in diesem angeordnet, wobei das Rührwerk mit einer oder mehreren nach unten offenen Kammern für die Magnete versehen ist. Ein besonders gleichmäßiger Andruck ergibt sich, wenn man im Rührwerk eine Ringnut vorsieht, in welcher ein Ringmagnet eingebettet ist. Das Rührwerk ist vorzugsweise als Scheibe ausgebildet, an deren Umfang ein oder mehrere Flügel angeordnet sind. Zweckmäßigerweise ist der Hohlkörper mit einer verschließbaren Einfüllöffnung zum Nachfüllen von Farbe oder Verdünnung versehen.If a hollow body with an agitator is used, the magnets are expediently arranged in this, the agitator being provided with one or more chambers for the magnets which are open at the bottom. A particularly even pressure is obtained if an annular groove is provided in the agitator, in which an annular magnet is embedded. The agitator is preferably designed as a disc, on the circumference of which one or more blades are arranged. The hollow body is expediently provided with a closable fill opening for refilling paint or thinner.

Der Hohlkörper 1 hat im wesentlichen eine quaderförmige Gestalt, wobei die Stirnwände 2 und 3 die Längswände 4 und 5 in der Draufsicht ein längliches Rechteck bilden. Er weist zwei nach unten offene, in sich geschlossene und ineinanderliegende Kammern 6 und 7 auf. Die Außenkammer 6 wird durch die Längswände 4 und 5 und die nach innen weisenden Flächen 10 und 11 Stirnwände 2 und 3 des Hohlkörpers 1 begrenzt. Dei Außenkammer 6 weist eine Farbabführung 12 auf. Die Innenkammer 7 ist symmetrisch in der Außenkammer 6 angelegt und wird begrenzt durch die sich jeweils gegenüberliegenden Querwände 13 und 14 und in gleicher Weise durch die Längswände 15 und 16. Die Innenkammer 7 ist ebenfalls als längliches Rechteck angelegt und bildet mit seinen Wänden die Innenwände der Außenkammer 6. Sie ist mit einer Farbzuführung 8 und einer Farbabführung 9 versehen.The hollow body 1 has essentially a cuboid shape, the end walls 2 and 3, the longitudinal walls 4 and 5 forming an elongated rectangle in plan view. It has two chambers 6 and 7 which are open at the bottom, closed and in one another. The outer chamber 6 is delimited by the longitudinal walls 4 and 5 and the inwardly facing surfaces 10 and 11 end walls 2 and 3 of the hollow body 1. The outer chamber 6 has a color drain 12. The inner chamber 7 is symmetrical in the outer chamber 6 and is delimited by the opposite transverse walls 13 and 14 and in the same way by the longitudinal walls 15 and 16.

In diesen sind Magnete, welche in der Zeichnung nicht dargestellt sind, mittels Schrauben eingespannt.From Fig. 2 it can be seen that the ink supply 8 opens into the inner chamber 7 via a channel 17. The ink supply channel 17 has a thread 18 in the upper area into which a line or the like can be screwed. The paint discharge 9 of the inner chamber 7 and the paint discharge 12 of the outer chamber 6 are designed in the same way as the paint feed 8. The longitudinal walls 4, 5 and 15, 16 of the two chambers 6 and 7 lie in the use position on a cliché, not shown in the drawing, and act as a doctor blade. For this purpose, the free ends of the walls 4, 5, 15, 16 are ground. In the two end walls 2 and 3 of the hollow body 1 there are pocket-shaped depressions 21 and 22, the openings of which also point towards the bottom of the hollow body 1. Magnets, which are not shown in the drawing, are clamped in these by means of screws.

Der Farbvorratsbehälter 23 weist eine zylindrische Gestalt auf, wobei der Hohlzylinder 24 am oberen Ende durch einen Deckel 25 und unteren Ende durch einen Boden 26 abgeschlossen ist. Im unteren Bereich des Hohlzylinders 24 ist eine Mischvorrichtung 27 und eine darunterliegende Umwälzpumpe 28 angebracht. Die Mischvorrichtung 27 und die Umwälzpumpe 28 werden über eine gelagerte Welle 29 im Sinne des Pfeils 30 durch einen nicht in der Zeichnung dargestellten Motor angetrieben. Durch eine Öffnung 31 im Deckel 25 wird die Welle 29 geführt. Die Welle 29 ist in einem Lager 32, welches im Deckel 25 angeordnet ist, drehbar gelagert.The ink reservoir 23 has a cylindrical shape, the hollow cylinder 24 being closed at the upper end by a cover 25 and the lower end by a base 26. In the lower region of the hollow cylinder 24, a mixing device 27 and a circulating pump 28 underneath are attached. The mixing device 27 and the circulation pump 28 are driven via a shaft 29 in the direction of arrow 30 by a motor, not shown in the drawing. Through an opening 31 in Cover 25, the shaft 29 is guided. The shaft 29 is rotatably supported in a bearing 32 which is arranged in the cover 25.

Das freie Ende der Welle 29 greift in einen Lagerzapfen 34, welcher im Boden 26 des Farbvorratsbehälters 23 angebracht ist. Im oberen Bereich des Farbvorratsbehälters 23 ist ein Behälter für Lösungsmittel 35 angeordnet. Der Behälter für Lösungsmittel 35, dessen Boden 36 eine ringartige Gestalt aufweist und auf dem ein Hohlzylinder 37 als Innenwandung angeordnet ist, wird mittels O-Ringe 38 im Hohlzylinder 24 des Farbvorratsbehälters 23 gehalten. Durch die kanalartige Öffnung des Hohlzylinders 37 ist der Behälter für Lösungsmittel 35 direkt mit der Mischvorrichtung 27 verbunden.The free end of the shaft 29 engages in a journal 34, which is attached in the bottom 26 of the ink reservoir 23. A container for solvent 35 is arranged in the upper region of the ink reservoir 23. The container for solvent 35, the base 36 of which has an annular shape and on which a hollow cylinder 37 is arranged as the inner wall, is held in the hollow cylinder 24 of the ink reservoir 23 by means of O-rings 38. Through the channel-like opening of the hollow cylinder 37, the container for solvent 35 is connected directly to the mixing device 27.

Die Welle 29 ist zentrisch durch den Kanal 39 des Behälters für Lösungsmittel 35 geführt. Im Bereich der Mischvorrichtung 27 ist auf der Welle 29 ein propellerartiges Rührwerk 40 angeordnet. Die Flügelflächen 41 des propellerartigen Rührwerks 40 durchmischen das in der Zeichnung nicht dargestellte Farbmedium mit den sich aus dem Behälter für Lösungsmittel 35 aufsteigenden und sich dann im Farbbehälter niedergeschlagenden Lösungsdämpfen. Unterhalb der Mischvorrichtung 27 befindet sich die Umwälzpumpe 28, welche ebenfalls über die Welle 29 angetrieben wird. Der Boden 26 des Farbvorratsbehälters 23 weist eine Öffnung 42 auf, welche über ein Gewinde einen Anschluß od. dgl. aufnehmen kann. Im Sinne der Pfeilrichtung 43 ist erkennbar, daß an die Öffnung 42 im Boden 26 des Farbvorratsbehälters 23 über nicht dargestellte Leitungen die Farbzuführung 8 des Hohlkörpers 1 angeschlossen ist. Im Bereich der Unwälzpumpe 28 ist eine weitere seitliche Öffnung 44 in der Wand des Hohlzylinders 24 angeordnet. Im Sinne der Pfeilrichtung 45 ist an der seitlichen Öffnung 44 die Farbabführung 9 der Innenkammer 7 und die Farbabführung 12 der Außenkammer 6 ebenfalls über nicht gezeigte Leitungen verbunden. Die Umwälzpumpe 28 saugt über die Öffnung 44 das Farbmedium wieder an.The shaft 29 is guided centrally through the channel 39 of the container for solvent 35. In the area of the mixing device 27, a propeller-type agitator 40 is arranged on the shaft 29. The wing surfaces 41 of the propeller-type agitator 40 mix the paint medium, not shown in the drawing, with the solution vapors rising from the container for solvent 35 and then being deposited in the paint container. The circulation pump 28, which is also driven by the shaft 29, is located below the mixing device 27. The bottom 26 of the ink reservoir 23 has an opening 42 which can receive a connection or the like via a thread. In the direction of the arrow 43 it can be seen that the opening 42 in the bottom 26 of the ink reservoir 23, the ink supply 8 of the hollow body 1 is connected via lines, not shown. In the area of the circulation pump 28, a further lateral opening 44 is arranged in the wall of the hollow cylinder 24. In the direction of the arrow 45, the paint discharge 9 of the inner chamber 7 and the paint discharge 12 of the outer chamber 6 are likewise connected via lines (not shown) at the lateral opening 44. The circulation pump 28 sucks in the color medium again through the opening 44.

Über die Leitungen zwischen den Kammern 6 und 7 des Hohlkörpers 1 und dem Farbvorratsbehälter 23 findet ein ständiger Farbaustausch statt. Die in der Mischvorrichtung 27 aufbereitete Farbe wird dabei durch die Umwälzpumpe 28 in den Hohlkörper gedrückt. Nicht auf dem Klischee verbleibende abgerakelte Farbe der Kammern 6 und 7 wird dann von der Umwälzpumpe 28 wieder abgesaugt und der Mischvorrichtung 27 zur Aufbereitung zugeführt. Das Rührwerk 40 der Mischvorrichtung 27 hält währenddessen das Farbmedium in Bewegung und durchmischt es mit den Lösungsdämpfen, welche sich aus dem Behälter für Lösungsmittel 35 im Bereich der Mischvorrichtung 27 niederschlagen.A constant color exchange takes place via the lines between the chambers 6 and 7 of the hollow body 1 and the ink reservoir 23. The color prepared in the mixing device 27 is pressed into the hollow body by the circulation pump 28. The doctored paint of the chambers 6 and 7 that does not remain on the cliché is then sucked off again by the circulation pump 28 and fed to the mixing device 27 for processing. The agitator 40 of the mixing device 27 in the meantime keeps the ink medium in motion and mixes it with the solution vapors which are deposited in the container for solvent 35 in the area of the mixing device 27.

Im Ausführungsbeispiel nach den Fign. 4 und 5 ist das Einfärb- und Rakelgerät ebenfalls als bodenloser Hohlkörper 51 gestaltet und liegt mit seiner offenen Seite 52 auf einem Klischee 53 auf. Dieses ist gegenüber dem Hohlkörper 51 in Pfeilrichtung 54 hin und her verschiebbar. Um im Innenraum 55 des Hohlkörpers 51 ein Eintrocknen der nicht dargestellten Farbe zu verhindern, ist ein Rührwerk 56 drehbar auf einer Welle 57 gelagert. Die Welle 57 ist durch den Deckel 58 des Hohlkörpers 51 durchgeführt und an ihrem oberen Ende 59 mit Gewinde 60 versehen. Auf dem Gewinde 60 ist eine Verstellmutter 61 angeordnet, welche sich ihrerseits am Hohlkörper 51 bzw. der Lagerbuchse 62 desselben abstützt. Durch Verdrehen der Verstellmutter 61 kann das Rührwerk 56 nach oben oder unten verschoben werden, wobei ein nicht dargestellter Anschlag dafür sorgt, daß immer ein Mindestabstand zwischen dem Rührwerk 56 und dem Klischee 53 bestehen bleibt.In the exemplary embodiment according to FIGS. 4 and 5, the inking and doctoring device is also designed as a bottomless hollow body 51 and lies with its open side 52 on a cliché 53. This can be moved back and forth relative to the hollow body 51 in the direction of the arrow 54. To in the interior 55 of the hollow body 51 To prevent drying of the paint, not shown, an agitator 56 is rotatably mounted on a shaft 57. The shaft 57 is passed through the cover 58 of the hollow body 51 and provided with thread 60 at its upper end 59. An adjusting nut 61 is arranged on the thread 60, which in turn is supported on the hollow body 51 or the bearing bush 62 thereof. By turning the adjusting nut 61, the agitator 56 can be moved up or down, a stop (not shown) ensuring that there is always a minimum distance between the agitator 56 and the cliché 53.

Ab oberen Ende der Welle 57 ist ein Klinkengetriebe 63 angeordnet, welches (Fig. 5) aus einem Schieber 64 mit den Klinken 65 und einem mit der Welle 57 verbundenen Rastrad 66 besteht. Das Klischee 53 ist in Pfeilrichtung 54 gegenüber dem Hohlkörper hin und her bewegbar und in der gleichen Richtung kann auch der Schieber 64 verschoben werden. Dies erfolgt über einen pneumatischen Hubzylinder 67, welcher vom Klischee 53 so gesteuert wird, daß die Bewegungen im entgegengesetzten Sinne erfolgen. Bei jedem Hub des Zylinders 67 wird das Rührwerk 56 um 120° verdreht. Durch diese Rotation wird die nicht gezeigte Farbe umgewälzt und am Antrocknen gehindert. An Stelle des Klinkengetriebes 63 kann zum Antrieb beispielsweise auch ein nicht dargestellter Elektromotor Verwendung finden.From the upper end of the shaft 57, a pawl gear 63 is arranged, which (FIG. 5) consists of a slide 64 with the pawls 65 and a ratchet wheel 66 connected to the shaft 57. The cliché 53 can be moved back and forth in the direction of the arrow 54 with respect to the hollow body, and the slide 64 can also be moved in the same direction. This is done via a pneumatic lifting cylinder 67, which is controlled by the cliché 53 so that the movements take place in the opposite sense. With each stroke of the cylinder 67, the agitator 56 is rotated by 120 °. This rotation circulates the color, not shown, and prevents it from drying. Instead of the ratchet mechanism 63, an electric motor (not shown) can also be used for the drive, for example.

Das Rührwerk 56 ist als Scheibe 68 ausgebildet und am Außenumfang mit mehreren Mischflügeln 69 versehen. Außerdem ist eine zum Klischee 53 hin offene Ringnut 70 vorgesehen, in welcher ein Ringmagnet 71 angeordnet ist. Dieser dient dazu, die als Rakel ausgebildete Unterkante 72 des Hohlkörpers 51 gleichmäßig an das Klischee 53 anzupressen. Zum Nachfüllen von Farbe oder Verdünnung ist im Hohlkörper 51 noch eine verschließbare Einfüllöffnung 73 angeordnet.The agitator 56 is designed as a disk 68 and on the outer circumference provided with several mixing blades 69. In addition, an annular groove 70, which is open toward the cliché 53, is provided, in which an annular magnet 71 is arranged. This serves to press the lower edge 72 of the hollow body 51, which is designed as a doctor blade, evenly onto the cliché 53. A closable filler opening 73 is also arranged in the hollow body 51 for refilling paint or thinner.
