Description

Die Erfindung betrifft eine Rotationstampondruckmaschine mit einer Gravurwalze mit vertikal stehender Drehachse, mit einer oder mehreren Tamponwalzen und einem Farbgebersystem zum Einfärben der Gravurwalze.The invention relates to a rotary pad printing machine with a gravure roll with vertical axis of rotation, with one or more pad rollers and a Farbgebersystem for coloring the gravure roll.

Rotationstampondruckmaschinen mit vertikal stehenden Gravurwalzen sind bekannt. Bei diesen Walzen besteht die Schwierigkeit, die Farbe gleichmäßig auf die Gravurwalze aufzubringen, so dass die Gravuren vollständig mit Druckfarbe gefüllt sind. Die US-A-5, 435, 873 zeigt ein Drucksystem mit Walzen mit horizontal liegenden Achsen.Rotary pad printing machines with vertically standing gravure rolls are known. These rollers have the difficulty of applying the ink evenly to the gravure roll so that the engravings are completely filled with ink. The US-A-5, 435, 873 shows a printing system with rollers with horizontal axes.

Aus der US-A-2, 096, 730 ist eine Druckvorrichtung bekannt, bei der die Walzen schräg stehen und die Gravurwalze von einem eine Archimedische Schraube aufweisenden Farbgebersystem eingefärbt wird. Die Farbe wird von der Gravurwalze auf ein Transportband übertragen, welches von einer Presswalze an die Gravurwalze angepresst wird.From the US-A-2, 096, 730 For example, a printing device is known in which the rollers are inclined and the engraved roller is inked by an inking system having an Archimedean screw. The ink is transferred from the gravure roll to a conveyor belt, which is pressed by a press roll to the gravure roll.

Dieses Problem wird erfindungsgemäß mit einer Rotationstampondruckmaschine gelöst, die die Merkmale des Anspruchs 1 aufweist.This problem is solved according to the invention with a rotary pad printing machine, which has the features of claim 1.

Bei der erfindungsgemäßen Rotationstampondruckmaschine wird die Druckfarbe, mit welcher die Gravurwalze eingefärbt wird, mittels einer Archimedischen Schraube aus der Farbauffangwanne gefördert und über die Leiteinrichtung auf die Umfangsfläche der Gravurwalze geleitet und somit die Gravuren eingefärbt. Von Vorteil ist, dass dieses System erfindungsgemäß berührungslos arbeitet im Gegensatz zu Systemen, die Einfärbewalzen verwenden. Außerdem ist dieses System unabhängig von der Höhe der Gravurwalze, da mittels der Archimedischen Schraube im in Rede stehenden Bereich die Druckfarbe auf jede Höhe gefördert werden kann. Durch die Einstellung des Dosierspaltes kann das System an die Eigenschaften der Farbe angepasst werden.In the rotary pad printing machine according to the invention, the printing ink with which the gravure roll is inked, conveyed by means of an Archimedian screw from the paint drip tray and passed over the guide on the peripheral surface of the gravure roll and thus colored the engravings. It is advantageous that this system works according to the invention without contact, in contrast to systems that use inking rollers. In addition, this system is independent of the height of the gravure roll, since by means of the Archimedian screw in the area in question, the ink can be promoted to any height. By adjusting the dosing gap, the system can be adapted to the properties of the paint.

Bei einer Weiterbildung ist vorgesehen, dass die Archimedische Schraube, die Farbauffangwanne und die Leiteinrichtung Teile des Farbgebersystems sind. Dies hat den wesentlichen Vorteil, dass das Farbgebersystem separat handhabbar ist, ohne dass hiervon die Gravurwalze oder die Tamponwalze betroffen sind. Es müssen demnach, insbesondere beim Wechsel der Druckfarbe, keine neuen Positionseinstellungen weder bei der Gravurwalze noch bei der Tamponwalze vorgenommen werden. Auch die Wartung und Reparatur kann einfacher durchgeführt werden, da das gesamte Farbgebersystem ausgetauscht werden kann.In a further development, it is provided that the Archimedean screw, the drip tray and the guide are parts of the Farbgebersystems. This has the significant advantage that the inking system is handled separately, without this, the gravure roll or the pad roller are affected. It must therefore, especially when changing the ink, no new position settings neither in the gravure roll at the pad roller can be made. Also, the maintenance and repair can be carried out easier because the entire color donor system can be replaced.

Die Leiteinrichtung ist vorteilhaft derart ausgebildet, dass sie die Ausgangsöffnung der Archimedischen Schraube umfasst und an die Umfangsfläche der Gravurwalze herangeführt ist. Auf diese Weise kann die Druckfarbe optimal an ihren Bestimmungsort geführt werden.The guide is advantageously designed such that it comprises the outlet opening of the Archimedean screw and is guided to the peripheral surface of the gravure roll. In this way, the ink can be optimally guided to their destination.

Mit Vorzug ist die Archimedische Schraube vertikal angeordnet. Es ist jedoch auch denkbar, dass die Archimedische Schraube geringfügig geneigt, insbesondere in Richtung auf die Gravurwalze geneigt ist.With preference the Archimedean screw is arranged vertically. However, it is also conceivable that the Archimedean screw is slightly inclined, in particular inclined in the direction of the gravure roll.

Um überschüssige Farbe problemlos auffangen zu können, ist unterhalb der Gravurwalze eine Sammeleinrichtung für von der Gravurwalze ablaufende Druckfarbe vorgesehen. Diese Sammeleinrichtung ist nach Art eines Sammelbeckens ausgebildet und besitzt einen geneigten Boden, der in die Farbauffangwanne des Farbgebersystems mündet. Auf diese Weise wird die von der Gravurwalze ablaufende Druckfarbe in das Farbgebersystem zurückgeführt.In order to be able to absorb excess paint easily, a collecting device for printing ink running from the gravure roll is provided below the gravure roll. This collecting device is designed in the manner of a Sammelbeckens and has a sloping bottom, which in the Ink collecting tray of Farbgebersystems opens. In this way, the running of the gravure roller ink is returned to the Farbgebersystem.

Eine besonders bevorzugte Ausführungsform sieht vor, dass die Archimedische Schraube von einem drehzahlregelbaren Antrieb angetrieben ist. Auf diese Weise kann die Fördermenge optimal an den Bedarf bzw. an die Art der Druckfarbe angepasst werden.A particularly preferred embodiment provides that the Archimedean screw is driven by a variable speed drive. In this way, the flow rate can be optimally adapted to the needs or to the type of ink.

Bei einer Weiterbildung ist vorgesehen, dass der Antrieb einen Sensor zur Ermittlung der Leistungsaufnahme aufweist. Mittels dieses Sensors kann die Leistung des Antriebs an sich ändernde Umgebungsbedingungen angepasst werden. Hierfür ist eine Überwachungseinrichtung vorgesehen, die die entsprechenden Regelkreise aufweist. So ist z.B. auch eine Zuführvorrichtung für Verdünner vorgesehen, falls die Farbdicke einen Schwellwert überschreitet.In a further development, it is provided that the drive has a sensor for determining the power consumption. By means of this sensor, the power of the drive can be adapted to changing environmental conditions. For this purpose, a monitoring device is provided which has the corresponding control circuits. For example, e.g. Also provided is a thinner feeder if the color thickness exceeds a threshold.

Vorzugsweise ist die Leiteinrichtung an die Höhe der Gravurwalze anpassbar. Auf diese Weise kann, wie bereits erwähnt, das gleiche Farbgebersystem bei unterschiedlich hohen Gravurwalzen, die z.B. Höhen von 50 mm, 100 mm usw. aufweisen können, verwendet werden.Preferably, the guide is adaptable to the height of the gravure roll. In this way, as already mentioned, the same inking system can be used with differently high gravure rolls, e.g. Heights of 50 mm, 100 mm, etc. may be used.

Um Umweltschutzbedingungen zu genügen und um das Verdunsten von Farbbestandteilen zu minimieren, ist das System im Wesentlichen geschlossen ausgeführt.To meet environmental conditions and to evaporate to minimize color components, the system is designed to be essentially closed.

Um sicher zu stellen, dass die Druckqualität konstant bleibt, ist die Tamponwalze mit einer Restfarbenabholung gekoppelt. Diese Restfarbenabholung, die z.B. als mitlaufende, auf den Tampon aufzupressende Walze ausgebildet ist, trägt an ihrem Umfang eine Farbabholfolie, die bei Bedarf ausgewechselt wird. Selbstverständlich kann auch ein Folienband auf die Umfangswalze der Tamponwalze aufgepresst und dadurch die Restfarbe abgehoben werden.To ensure that the print quality remains constant, the pad roller is coupled with a residual ink pickup. This residual color pickup, e.g. is designed as a revolving, aufzupressende on the tampon roller carries at its periphery a Farbabholfolie, which is replaced if necessary. Of course, a film strip can be pressed onto the peripheral roller of the pad roller and thereby the residual color are lifted.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im Einzelnen beschrieben ist.Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail.

In der Zeichnung zeigen:

In the drawing show:
FIG. 1
a side view of the rotary pad printing machine according to the invention; and
FIG. 2
a top view of the Rotationsstampondruckamschine according to Figure 1.

Die Figur 1 zeigt eine insgesamt mit 10 bezeichnete Rotationstampondruckmaschine in Seitenansicht, wobei mit 12 eine Tamponwalze bezeichnet ist, die an einer vertikal stehenden Drehachse 14 befestigt ist. Die Drehachse 14 wird angetrieben über ein Zahnrad 16, welches mit einem Zahnrad 18 kämmt, das an einer Welle 20 befestigt ist. Die Drehachse 14 ist in Lagern 22 hoch präzise gelagert.FIG. 1 shows a side view of a rotary pad printing machine designated overall by 10, where 12 denotes a pad roller which is fastened to a vertical axis of rotation 14. The axis of rotation 14 is driven by a gear 16, which meshes with a gear 18 which is fixed to a shaft 20. The axis of rotation 14 is mounted in bearings 22 highly accurate.

An der Welle 20, die eine senkrecht stehende Drehachse 24 bildet, ist eine Gravurwalze 26 drehfest befestigt, auf welcher die Tamponwalze 12 abrollt. Auch die Welle 20 ist in entsprechenden Lagern 28 hoch präzise gelagert.On the shaft 20, which forms a vertical axis of rotation 24, a gravure roller 26 is rotatably mounted, on which the pad roller 12 rolls. Also, the shaft 20 is mounted in corresponding bearings 28 highly accurate.

Seitlich neben der Gravurwalze 26 befindet sich ein insgesamt mit 30 bezeichnetes Farbgebersystem, welches eine Farbauffangwanne 32 aufweist, in welcher Druckfarbe gesammelt wird. In diese Farbauffangwanne 32 taucht eine Archimedische Schraube 34 ein, welche senkrecht ausgerichtet ist und an ihrer Oberseite mit einem Antrieb 36 gekoppelt ist. Die Austragsöffnung 38 der Archimedischen Schraube 34 befindet sich ebenfalls an der Oberseite und mündet in eine Leiteinrichtung 40, welche in Richtung auf die Umfangsfläche 42 der Gravurwalze 32 gerichtet ist. Dabei befindet sich die Spenderöffnung 44 der Leiteinrichtung 40 in unmittelbarer Nachbarschaft zur Gravurwalze 26 und ist lediglich über einen Dosierspalt 46 von dieser beabstandet. Die Spenderöffnung 44 ist auch an die Krümmung der Umfangsfläche 42 angepasst, so dass der Dosierspalt 46 sich nicht ändert. Die Höhe der Spenderöffnung 44 entspricht im Wesentlichen der Höhe der Gravurwalze 26, so dass diese über ihren gesamten Umfang eingefärbt wird. Die Leiteinrichtung 40 ist zwischen der Spenderöffnung 44 und der Austragsöffnung 38 der Archimedischen Schraube 34 im Wesentlichen als Kanal 48 ausgeführt und stetig nach unten geneigt. Beim Stillstand der Archimedischen Schraube 34 läuft dieser Kanal 48 somit leer.Located to the side of the gravure roller 26 is a generally designated 30 Farbgebersystem which has a drip tray 32, in which ink is collected. An Archimedean screw 34, which is aligned vertically and is coupled to a drive 36 on its upper side, dives into this ink collecting tray 32. The discharge opening 38 of the Archimedean screw 34 is also located at the top and opens into a guide 40 which is directed towards the peripheral surface 42 of the gravure roll 32. In this case, the dispensing opening 44 of the guide 40 is in the immediate vicinity of the gravure roller 26 and is only spaced by a metering gap 46 of this. The dispensing opening 44 is also adapted to the curvature of the peripheral surface 42 so that the metering gap 46 does not change. The height of the dispenser opening 44 substantially corresponds to the height of the gravure roller 26, so that it is colored over its entire circumference. The guide device 40 is executed between the dispensing opening 44 and the discharge opening 38 of the Archimedean screw 34 substantially as a channel 48 and inclined steadily downwards. When the Archimedean screw 34, this channel 48 thus runs empty.

Unterhalb der Gravurwalze 26 befindet sich eine Sammeleinrichtung 50, in welcher von der Umfangsfläche 42 ablaufende Druckfarbe gesammelt und in Richtung der Farbwanne 32 geleitet wird. Hierfür besitzt die Sammeleinrichtung 50 einen geneigten Boden 52, der oberhalb eines Auffangmundes 54 der Farbwanne 32 in einem schüttenartigen Auslass 56 endet.Below the gravure roll 26 is a collecting device 50, in which ink discharged from the peripheral surface 42 is collected and conducted in the direction of the ink tray 32. For this purpose, the collecting device 50 has a sloping bottom 52, which ends above a collecting mouth 54 of the ink tray 32 in a pour-like outlet 56.

Der Antrieb 36 ist mit einem (nicht dargestellten) Sensor versehen, welcher die Leistungsaufnahme des Antriebs 36 ermittelt und die Information einer Überwachungseinrichtung zuleitet. Überschreitet die Leistungsaufnahme des Antriebs 36 aufgrund eingedickter Druckfarbe einen voreingestellten Wert, wird der Druckfarbe Verdünner zugeführt, so dass die Viskosität wieder abgesenkt wird. Dies kann über einen Regelkreis automatisch erfolgen. Außerdem kann ein Niveausensor in der Farbauffangwanne 32 vorgesehen sein, der einen zu niedrigen Füllstand meldet.The drive 36 is provided with a sensor (not shown), which determines the power consumption of the drive 36 and supplies the information to a monitoring device. Exceeds the power of the drive 36 due to thickened ink a preset value, the ink is supplied thinner, so that the Viscosity is lowered again. This can be done automatically via a control loop. In addition, a level sensor 32 may be provided in the drip pan, which reports a too low level.

Der Einfachheit halber wurde auf die Darstellung einer Rakel und einer Restfarbenabholung verzichtet.For the sake of simplicity, the representation of a squeegee and a residual ink pickup was dispensed with.

Die Figur 2 zeigt eine Draufsicht auf die Rotationstampondruckmaschine 10 und es ist deutlich die Leiteinrichtung 40 zu erkennen, die direkt in den Bereich der Umfangsfläche 42 der Gravurwalze 26 herangeführt ist. Ferner sind noch Zahnräder 58 und 60 dargestellt, welche die beiden Zahnräder 16 und 18 antreiben. Mittels Einstellvorrichtungen 62, 64 und 66 kann die Position der Gravurwalze 26, die Position der Tamponwalze 12, kann der Anpressdruck der Tamponwalze 12 auf die Gravurwalze 26, kann der Anpressdruck der Rakel an die Umfangsfläche 42 der Gravurwalze 26 und können die Höhenlagen der Walzen 12 und 26 eingestellt werden.FIG. 2 shows a plan view of the rotary pad printing machine 10 and it is clearly visible the guide device 40, which is brought directly into the region of the circumferential surface 42 of the gravure roller 26. Furthermore, gears 58 and 60 are still shown, which drive the two gears 16 and 18. By means of adjusting devices 62, 64 and 66, the position of the gravure roll 26, the position of the tampon roll 12, the contact pressure of the tampon roll 12 on the gravure roll 26, the contact pressure of the doctor blade on the peripheral surface 42 of the gravure roll 26 and can the heights of the rollers 12th and 26 are set.

Hervorzuheben ist noch, dass das Farbgebersystem 30 als separat handhabbares Bauteil ausgebildet ist, welches z.B. bei einem Wechsel der Druckfarbe nur ausgetauscht werden muss.It should also be emphasized that the inking system 30 is designed as a component which can be handled separately, which is used e.g. when changing the ink only needs to be replaced.
