Description

Druckanlagepressure system
Die Erfindung betrifft eine Druckanlage gemäß dem Oberbegriff des Anspruchs 1 .The invention relates to a printing system according to the preamble of claim 1.
Die Innenflächen von Verschlüssen, insbesondere Schraubverschlüssen, für Behäl- ter, insbesondere Flaschen, werden immer häufiger zu Werbezwecken verwendet.The inner surfaces of closures, in particular screw closures, for containers, in particular bottles, are increasingly being used for advertising purposes.
Zur Darstellung von Bildern und/oder Texten auf solchen Innenflächen sind schon Dichtungsscheiben aus Kunststoff eingesetzt worden, die getrennt vom Verschluss bedruckt und dann in den Verschluss eingepresst wurden. Bei Verschlüssen, die nicht mit einer getrennten Dichtungsscheibe arbeiten, sondern bei denen die Innenfläche des Verschlusses bereits mit dem Dichtungsmäterial beschichtet ist, oder bei Verschlüssen ohne Dichtungseinlage ist die genannte Methode zur An- bringung von Werbung auf der Innenseite des Verschlusses nicht anwendbar.Plastic sealing washers have already been used to display images and / or texts on such inner surfaces, which have been printed separately from the closure and then pressed into the closure. For closures that do not work with a separate sealing washer, but for which the inner surface of the closure is already coated with the sealing material, or for closures without a sealing insert, the method mentioned for applying advertising on the inside of the closure cannot be used.
Bekannt ist auch, beispielsweise durch die US-A-6244172 und die WO-A- 99/14334, die Innenflächen von Verschlüssen mit üblichen Tampondruckmaschinen zu bedrucken, indem mehrere Einzeltampons vorgesehen werden, die in die Verschlüsse eingeführt werden und dann die mitgeführte Druckfarbe an den Innenflächen der Verschlüsse absetzen. Dadurch lassen sich zwar farbige Abdrucke, auch weiße Abdrucke, erzeugen, aber eine solche Tampondruckmaschine ist nur für verhältnismäßig kleine Stückzahlen geeignet und kann nur als eigenständige Druckmaschine eingesetzt werden, die einen verhältnismäßig hohen Personalaufwand und Platzbedarf erfordert.It is also known, for example from US-A-6244172 and WO-A-99/14334, to print the inner surfaces of closures with conventional pad printing machines by providing several individual tampons which are inserted into the closures and then the ink carried along the inner surfaces of the closures. Although colored impressions, including white impressions, can be produced in this way, such a tampon printing machine is only suitable for relatively small quantities and can only be used as an independent printing press, which requires a relatively large amount of personnel and space.
BESTÄT.GUMGSKOPIE Durch die JP-A-58124653 ist eine Tampondruckmaschine bekannt, die zwei rotierende Trommeln aufweist, von denen die eine auf ihrem Umfang verteilte Tampons und die andere auf ihrem Umfang verteilte Halter für zu bedruckende, unebene Gegenstände aufweist, wobei die Halter zum Trommelzentrum hier beweglich sind. Die bekannte Druckmaschine betrifft nur den Außendruck; der Innendruck von Verschlusskappen wird nicht berührt.BESTÄT.GUMGSKOPIE JP-A-58124653 discloses a tampon printing machine which has two rotating drums, one of which has tampons distributed over its circumference and the other has holders for uneven objects to be printed, distributed over its circumference, the holders being movable here towards the drum center are. The known printing press only affects the outside pressure; the internal pressure of the caps is not affected.
Ferner kommen für die Darstellung von Werbeaussagen auf den Innenflächen von Verschlüssen Laserbeschriftungsanlagen in Frage, die für höhere Leistungen und verhältnismäßig hohe Stückzahlen mit Mehrfachlaserköpfen ausgestattet werden können. Solche Laserbeschriftungsanlagen können jedoch nur auf hellen Verschlüssen eine dunkle Beschriftung erzeugen. Auf dunklen Verschlüssen ist die eingebrannte Gravur nur sehr schwer zu erkennen. Diese Laserbeschriftungsanlagen sind ebenfalls nur als eigenständige Anlagen möglich, die einen entsprechend hohen Platzbedarf und Personalaufwand erfordern und mit sehr hohen Anschaffungskosten verbunden sind.Furthermore, laser marking systems can be used for the display of advertising messages on the inner surfaces of closures, which can be equipped with multiple laser heads for higher outputs and relatively large numbers. However, such laser marking systems can only produce dark lettering on light closures. The burned-in engraving is very difficult to recognize on dark closures. These laser marking systems are also only possible as independent systems that require a correspondingly large amount of space and personnel and are associated with very high acquisition costs.
Die Aufgabe der Erfindung besteht darin, eine Druckanlage der im Oberbegriff desThe object of the invention is a printing system in the preamble of
Anspruchs 1 genannten Art zu schaffen, die einen niedrigen Platzbedarf und einen geringen Personalaufwand hat und deren Anschaffungskosten gering sind.To create claim 1 type mentioned, which has a low space requirement and a low personnel expenditure and the acquisition costs are low.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Die Druckanlage gemäß der Erfindung hat den Vorteil, dass keine zusätzliche, eigenständige Druckmaschine notwendig ist, und den weiteren Vorteil dass bekannte und bestehende Druckmaschinen weiterverwendet werden können und nur ergänzt zu werden brauchen. Gemäß einer weiteren Ausbildung der Erfindung trägt der Stößel an seinem Außenende eine in den Dorn versenkt angeordnete Platte zur Anbringung des Tampons. Der Tampon liegt daher geschützt im Dorn.The printing system according to the invention has the advantage that no additional, independent printing press is necessary, and the further advantage that known and existing printing presses can continue to be used and only need to be supplemented. According to a further embodiment of the invention, the plunger carries at its outer end a plate sunk into the mandrel for attaching the tampon. The tampon is therefore protected in the mandrel.
Gemäß einer zweckmäßigen, weiteren Ausbildung der Erfindung ist der Tampon eine Silikonscheibe, die nach außen gewölbt sein kann.According to an expedient, further development of the invention, the tampon is a silicone disk which can be curved outwards.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung trägt jeder Stößel an seinem Innenende ein Laufrad, das über feststehende oder steuerbare Nocken zur Farbaufnahme und -abgäbe gesteuert wird.According to a simple, further embodiment of the invention, each tappet carries an impeller at its inner end, which is controlled by fixed or controllable cams for ink absorption and release.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung erfolgt die Farbauf- nähme von einer Klischeewalze.According to a simple, further embodiment of the invention, the ink is picked up by a plate roller.
Gemäß einer einfachen, weiteren Ausbildung der Erfindung ist zur Farbabgabe eine auf die Außenfläche des Verschlusses wirkendes Andruckmittel vorgesehen.According to a simple, further embodiment of the invention, a pressure means acting on the outer surface of the closure is provided for ink delivery.
Die Erfindung wird nun anhand von Ausführungsbeispielen näher erläutert. Es zeigen:The invention will now be explained in more detail on the basis of exemplary embodiments. Show it:

Fig. 4 einen Schnitt durch einen alternativen Dorn gemäß der Erfindung.Fig. 4 shows a section through an alternative mandrel according to the invention.
In Fig. 1 ist eine Druckanlage gemäß der Erfindung im Prinzip dargestellt. Die Druckanlage besteht im Wesentlichen aus einem Gehäuse 1 , einem darin eingebauten Rotationsträger in Form eines an sich bekannten Rotationsgroßrades 2, vier im Gehäuse 1 eingebauten Druckwerken 3 - 6 für vier verschiedene Farben für den Außendruck und einem Druckwerk 7 für den Innendruck von Verschlüssen, wie den Verschlüssen 8. Das Gehäuse 1 weist ferner eine Steuertafel 9 zur Steuerung des Rotationsgroßrades 2 und der Druckwerke 3 - 7 auf. Das Rotationsgroßrad 2 wird im Betrieb entgegen dem Uhrzeigersinn angetrieben. Die Druckwerke 3 - 6 arbeiten jeweils mit einer Zwischenwalze, wie der Zwischenwalze 10. Auf dem Umfang des Rotationsgroßrades 2 sind eine Vielzahl von Dornen, wie die Dorne, 1 1 , befestigt, die in besonderer Weise ausgebildet sind, wie noch näher erläutert wird. Diese Dornen fahren an einer Klischeewalze 12 des Druckwerkes 7 vorbei.In Fig. 1, a printing system according to the invention is shown in principle. The printing system essentially consists of a housing 1, a rotary support built into it in the form of a known large rotating wheel 2, four printing units 3 - 6 installed in the housing 1 for four different colors for external printing and a printing unit 7 for the internal printing of closures, such as the closures 8. The housing 1 also has a control panel 9 for controlling the large rotating wheel 2 and the printing units 3-7. The large rotating wheel 2 is driven counterclockwise during operation. The printing units 3-6 each work with an intermediate roller, such as the intermediate roller 10. On the circumference of the large rotating wheel 2, a plurality of spikes, such as the spikes, 1 1, are fastened, which are designed in a special way, as will be explained in more detail. These thorns pass a cliché roller 12 of the printing unit 7.
In Fig. 2 sind dieser Vorgang und die Dorne näher dargestellt. Ausschnittsweise sind fünf Dorne 1 1 , - 1 15 gezeigt, die am Rotationsrad 2 befestigt sind. Diese Dorne sind alle gleich ausgebildet, so dass die Beschreibung eines Dorns, beispielsweise des Dorns 1 13, genügt.2, this process and the mandrels are shown in more detail. A section of five mandrels 1 1, - 1 1 5 are shown, which are attached to the rotary wheel 2. These mandrels are all of the same design, so that the description of a mandrel, for example the mandrel 1 1 3 , is sufficient.
Der Dorn 1 13 weist einen runden Dornkörper 13 auf, der in das RotationsgroßradThe mandrel 1 1 3 has a round mandrel body 13 which is in the large rotating wheel
2 eingeschraubt ist. Der Dornkörper 13 ist mit einem in seiner Längsrichtung verlaufenden, zentralen Kanal 14 versehen, in dem ein unter Federdruck stehender Stößel 15 längsbewegbar geführt ist. An seinem Außenende trägt der Stößel 15 einen Tampon 1 6, vorzugsweise in Form einer runden Silikonscheibe mit einer Außenwölbung. An seinem Innenende ist der Stößel 15 mit einem Laufrad 17 versehen.2 is screwed in. The mandrel body 13 is provided with a central channel 14 running in its longitudinal direction, in which a plunger 15 under spring pressure is guided so as to be longitudinally movable. The plunger 15 bears at its outer end a tampon 1 6, preferably in the form of a round silicone disc with an outer curvature. The plunger 15 is provided with an impeller 17 at its inner end.
Bei der Bewegung des Rotationsgroßrades 2 gelangen die Dorne' 1 1 , - 1 1 5 nacheinander zur Klischeewalze 1 2. Dabei werden die Stößel in Richtung auf die Klischeewalze 1 2 mittels eines feststehenden Nockens 1 8 ausgelenkt. Gezeigt ist, dass der Stößel 1 5 gerade durch den Nocken 1 8 ausgestoßen wird, wobei sich die mit Farbe benetzte Klischeewalze 1 2 am Tampon 1 6 abwälzt und die Farbe auf diesen Tampon überträgt. Der Nocken 1 8 könnte auch steuerbar sein, um so durch sein Wegschwenken die Abnahme von Farbe von der Klischeewalze 1 2 zu unterbrechen und damit die Anzahl der von innen bedruckten Verschlüsse 8 steuern zu können.During the movement of the large rotating wheel 2, the mandrels ' 1 1, - 1 1 5 successively reach the cliché roller 1 2. The rams are deflected in the direction of the cliché roller 1 2 by means of a fixed cam 1 8. It is shown that the plunger 1 5 is just ejected through the cam 1 8, the cliché roller 1 2 wetted with paint rolling on the tampon 1 6 and transferring the color to this tampon. The cam 1 8 could also be controllable so as to interrupt the removal of ink from the printing plate roller 1 2 by pivoting it away and thus to be able to control the number of closures 8 printed from the inside.
Den Dornen 1 1 mit den auf diese Weise mit Druckbildern versehenen Tampons wird nun nach Fig. 1 aus einem Magazin 1 9 ein Band 20 mit hintereinander angeordneten Verschlüssen, wie den Verschlüssen 21 , zugeführt, wobei sich die Dorne 1 1 in die Verschlüsse 21 setzen. Dieser Vorgang ist näher in Fig. 3 dargestellt.According to FIG. 1, the mandrels 11 with the tampons provided with printed images in this way are now fed a tape 20 with closures, such as the closures 21, arranged one behind the other, the mandrels 11 being placed in the closures 21 , This process is shown in more detail in Fig. 3.
In Fig. 3 sind vier Dorne gezeigt, deren Tampons mit Farbe versehen sind. Den Dornen werden die Verschlüsse 21 über eine Gleitführung 22 derart zugeführt, dass die Dorne mit den Tampons allmählich in die Verschlüsse 21 tauchen. In Fig.In Fig. 3 four mandrels are shown, the tampons are provided with color. The closures 21 are fed to the mandrels via a slide guide 22 such that the mandrels with the tampons gradually dip into the closures 21. In Fig.
3 ist dargestellt, dass der Verschluss 21 gerade in eine Fassung 23 des Dorns 1 13 aufgenommen ist und der zugehörige Stößel 1 5 des Dorns 1 13 gerade mittels eines weiteren feststehenden Nockens 24 in Richtung auf den Verschluss 21 ausgestoßen wird. Dabei überträgt der zugehörige Tampon 1 6 das Druckbild auf die Innen- seite des Verschlusses 21 . Eine Andruckwalze 25 dient dabei als Widerlager. Anstelle einer Andruckwalze kann auch eine Andruckplatte oder Andruckkurve eingesetzt werden.3 shows that the closure 21 is just received in a socket 23 of the mandrel 1 1 3 and the associated plunger 15 of the mandrel 1 1 3 is just ejected in the direction of the closure 21 by means of a further fixed cam 24. The associated tampon 1 6 transfers the printed image to the inside of the closure 21. A pressure roller 25 serves as an abutment. Instead of a pressure roller, a pressure plate or pressure curve can also be used.
In Fig. 1 werden in der Folge die innen bedruckten Verschlüsse 21 an einer Vorbehandlungsvorrichtung 26 vorbei an den Druckwerken 3 - 6 zugeführt, durch die sie einen Vierfarbaußendruck erhalten, ehe sie über eine Weiche 27 die Druckanlage verlassen. Die Vorbehandlungseinrichtung 26 bereitet die Außenflächen der Verschlüsse 21 für den Druck mit den Druckwerken 3 - 6 vor.In Fig. 1, the internally printed closures 21 are fed past a pretreatment device 26 past the printing units 3-6, through which they receive a four-color outer print before they leave the printing system via a switch 27. The pretreatment device 26 prepares the outer surfaces of the closures 21 for printing with the printing units 3-6.
In Fig. 4 ist ein alternativer Dorn 1 1 ' gezeigt, dessen Dornkörper 13' an seinem Außenende abweichend von den vorhergehenden Figuren mit einer Ausnehmung 28 versehen ist. Das Außenende des Stößels 15 trägt ferner eine vorzugsweise runde Platte 29, auf der der Tampon 16 befestigt ist. Platte 29 und Tampon 16 werden in der Ausnehmung 28 geschützt aufgenommen.4 shows an alternative mandrel 11 ', the mandrel body 13' of which is provided with a recess 28 at its outer end, in a departure from the previous figures. The outer end of the plunger 15 also carries a preferably round plate 29 on which the tampon 16 is attached. Plate 29 and tampon 16 are received in a protected manner in the recess 28.
Das Rotationsgroßrad 2 kann, wie nicht dargestellt ist, mit mehr als einem Ring , aus Dornen bestückt sein, wobei die zusätzlichen Ringe auf dem Außenumfang nebeneinander angeordnet sind. Dadurch kann die Effektivität der Druckanlage noch wesentlich gesteigert werden. Entgegen der Darstellung in den Figuren kann die Druckanlage auch mit einer geringeren Anzahl von Außendruckwerken, einem Innendruckwerk und mit einem Rotationsflachband statt eines Rotationsgroßrades betrieben werden. The large rotating wheel 2 can, as is not shown, be equipped with more than one ring made of thorns, the additional rings being arranged next to one another on the outer circumference. This can significantly increase the effectiveness of the printing system. Contrary to the representation in the figures, the printing system can also be operated with a smaller number of external printing units, an internal printing unit and with a flat rotating belt instead of a large rotating wheel.
