"Packmittel" sind im Sinne der Erfindung Verpackungen oder Behältnisse, die im Lebensmittelbereich und dabei speziell auch im Getränkebereich üblicherweise verwendet werden, und zwar insbesondere Behälter, wie z. B. Flaschen, Dosen, auch Weichverpackungen, beispielsweise solche hergestellt aus Karton und/oder Kunststofffolie und/oder Metallfolie."Packaging" in the context of the invention, packaging or containers that are common in the food industry and especially in the beverage sector be used, and in particular containers such. As bottles, cans, soft packaging, such as those made of cardboard and / or plastic film and / or metal foil.
Unter "Puck" ist im Sinne der Erfindung eine Halte-, Zentrier- und Ausrichteinheit für die Packmittel zu verstehen, an der das jeweilige Packmittel gehalten von dem Packmitteleinlauf an den Packmittelauslauf durch eine Packmittel-Transportstrecke des Transportsystems bewegt wird und welches hierbei bevorzugt auch eine gesteuerte Orientierung des jeweiligen Packmittels für dessen Behandlung bewirkt.For the purposes of the invention, the term "puck" is to be understood as meaning a holding, centering and aligning unit for the packaging means, at which the respective packaging material is moved from the package inlet to the package outlet through a package transport path of the transport system and which preferably also has one controlled orientation of the respective packaging material causes for its treatment.
"Transportmäßig an einander anschließenden Transportelemente" bedeutet im Sinne der Erfindung Transportelemente oder Transport- und Behandlungselemente, die so ausgebildet und angeordnet sind, dass sie an Übergabebereichen die Pucks von einem benachbarten in einer Transportrichtung vorausgehenden Transportelement aufnehmen, halten und an ein in Transportrichtung folgendes Transportelement weiterleiten."Transport moderately to each other adjacent transport elements" means in the context of the invention transport elements or transport and treatment elements that are designed and arranged so that they receive at transfer areas, the pucks of an adjacent in a transport direction preceding transport element, hold and to a following in the transport direction transport element hand off.
Der Ausdruck "im Wesentlichen" bzw. "etwa" bedeutet im Sinne der Erfindung Abweichungen vom jeweils exakten Wert um +/- 10%, bevorzugt um +/- 5% und/oder Abweichungen in Form von für die Funktion unbedeutenden Änderungen.The expression "essentially" or "approximately" in the sense of the invention means deviations from the exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes that are insignificant for the function.
Weiterbildungen, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung von Ausführungsbeispielen und aus den Figuren.Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures.
Insbesondere wird eine Halte- und Zentriereinheit offenbart und beansprucht, bei der das Sekundärteil, in dem das Packmittel, die Flasche oder der Behälter gehalten wird, um eine vertikale Achse drehbar und antreibbar an oder in einem Primärteil gelagert ist, und weiterhin motorisch antreibbar ist. Hierbei kann in eine Ausführungsform, der bevorzugten, vorgesehen werden, dass das Sekundärteil den Rotor eines elektromagnetischen Direktantriebes bildet, und so das gesteuerte Ausrichten und/oder Drehen des jeweiligen Packmittels erfolgt. Hierfür wird vorzugsweise das Sekundärteil mit einer Permanentmagnetanordnung versehen, die mit einem Stator des elektromagnetischen Direktrehantriebes oder mit einer diesen Stator bildenden Elektromagnetanordnung zusammenwirkt.In particular, a holding and centering unit is disclosed and claimed in which the secondary part in which the packaging material, the bottle or the container is held, about a vertical axis rotatably and drivably mounted on or in a primary part, and is further driven by a motor. Here, in an embodiment, the preferred, be provided that the secondary part forms the rotor of an electromagnetic direct drive, and so the controlled alignment and / or rotation of the respective packaging takes place. For this purpose, the secondary part is preferably provided with a permanent magnet arrangement which cooperates with a stator of the electromagnetic direct rotary drive or with a stator assembly forming this electromagnet arrangement.
Alternativ hierzu kann das Sekundärteil auch einen stufenlos regel- und steuerbarer elektrischer Motor, insbesondere einen Servomotor umfassen oder in einer Hauptkomponente aus einem solchen Motor bestehen. In diesem Fall umfasst das Primärteil in einer Hauptkomponente das Motorgehäuse bzw. besteht im Wesentlichen aus dem Motorgehäuse eines stufenlos regel- und steuerbaren Motors. Da zu jedem Zeitpunkt die Winkelstellung des Rotors respektive des Packmittels sein muss, ist idealerweise am Sekundärteil, ggf. auch am Primärteil, wenigstens eine Kodierung für die Drehwinkellage vorgesehen, welche mit einem geeigneten Sensor oder Leseeinheit, insbesondere einem oder mehreren Inkremental-Sensoren an der jeweiligen Arbeitsposition zusammenwirkt. Weiterhin kann alternativ oder ergänzende das Primärteil relativ zur jeweiligen Behandlungspositionen in seiner Drehwinkellage immer eindeutig bestimmt oder bestimmbar ausgeführt sein, indem eine formschlüssige Aufnahme, Zentriereinheit oder ein Kupplungselement vorgesehen ist, so dass nur die relative Drehwinkellage des Sekundärteils zum Primärteil durch einen Sensor, eine Leseeinheit etc. erfassbar gestaltet sein muss. Die Lage relativ zum Drucksegment bzw. dem Druckkopf kann dann hieraus abgeleitet werden.Alternatively, the secondary part may also comprise a continuously variable and controllable electric motor, in particular a servomotor, or consist of such a motor in a main component. In this case, the primary part in a main component comprises the motor housing or consists essentially of the motor housing of a continuously variable and controllable motor. Since the angular position of the rotor or the packaging must be at any time, at least one coding for the rotational angle position is ideally provided on the secondary part, possibly also on the primary part, which with a suitable sensor or reading unit, in particular one or more incremental sensors on the cooperates with each work position. Furthermore, alternatively or in addition, the primary part relative to the respective treatment positions in its angular position can always be clearly determined or determinable executed by a positive receptacle, centering or coupling element is provided so that only the relative angular position of the secondary part to the primary part by a sensor, a reading unit etc. must be designed detectable. The position relative to the printing segment or the print head can then be derived therefrom.
Bei der Bedruckung von leeren Packmitteln, insb. PET-, PEN-, PE- oder PP-Leerflaschen, was den Normalfall darstellt, sollte vorteilhafterweise das Packmittel unter leichten Überdruck stehen. Hierzu wird an der Halte- und Zentriereinheit ein Konter- oder Gegenstück zu einem maschinen- oder drucksegmentseitigen Kupplungselement vorgesehen, das insbesondere in der Art einer Schnellkupplung ausgebildet ist. Hierüber kann ein dampf- oder gasförmigen Medium, z.B. Druckluft, durch eine innere Leitung, hier der hohle Innerraum des Pucks, in das Packmittel geleitet werden. Der untere Auslass dieser inneren Leitung bildet im idealerweise ein zentrales Zentrierelement/-konus. Hierfür ist mindestens ein Transport- und Behandlungseinheit, idealerweise die erste, mit einer Dampf- oder Gasquelle verbunden oder umfasst einen geeigneten Kompressor.When printing on empty packaging, in particular PET, PEN, PE or PP empty bottles, which is the normal case, the packaging should advantageously be under slight overpressure. For this purpose, a counterpart or counterpart to a machine or pressure segment-side coupling element is provided on the holding and centering unit, which is designed in particular in the manner of a quick coupling. Over this, a vapor or gaseous medium, e.g. Compressed air, through an inner pipe, here the hollow inner space of the puck, into which packaging material is directed. The lower outlet of this inner conduit ideally forms a central centering element / cone. For this purpose, at least one transport and treatment unit, ideally the first, is connected to a steam or gas source or comprises a suitable compressor.
Vorteilhafterweise wird das Konterelement der Kupplung als Rückschlagventil ausgebildet oder ein Rückschlagventil ist in der inneren Leitung vorgesehen. Hierdurch kann nach dem Vorspannen mit einem dampf- und/oder gasförmigen Medium, z.B. Druckluft, dieser Druck über die gesamte Packmitteltransport- bzw. Druckstrecke im Packmittel erhalten werden.Advantageously, the counter element of the coupling is designed as a check valve or a check valve is provided in the inner pipe. As a result, after being prestressed with a vaporous and / or gaseous medium, for example compressed air, this pressure can be obtained over the entire package transport or pressure section in the packaging.

Zum Bedrucken werden die Packmittel 2 der Vorrichtung 1 bzw. deren Packmitteleinlauf 1.1 über einen äußeren Transporteur aufrecht stehend in einer Transportrichtung A zugeführt, bewegen sich dann innerhalb der Vorrichtung 1 auf einer mehrfach bogenförmig umgelenkten Transportstrecke. Nach dem Bedrucken werden die Packmittel 2 weiterhin aufrecht stehend an einem Packmittelauslauf 1.2 über einen äußeren Transporteur einer weiteren Verwendung zugeführt. Der Transportweg der Packmittel 2 beim Zuführen, beim Bewegen durch die Vorrichtung 1 sowie beim Wegführen aus der Vorrichtung 1 ist in der
Im Einzelnen besteht die Vorrichtung 1 aus mehreren in Transportrichtung A unmittelbar aneinander anschließenden Modulen 4.1 - 4.n, und zwar bei der dargestellten Ausführungsform aus insgesamt acht Modulen 4.1 - 4.8, wobei sämtliche Module 4.1 - 4.8 jeweils von einer identischen Grundeinheit 5 gebildet sind, die mit den für die spezielle Aufgabe des jeweiligen Moduls 4.1 - 4.8 notwendigen Funktionselementen ausgestattet ist.In detail, the
Jede Grundeinheit 5 umfasst u.a. eine in einem Modulgehäuse 6 untergebrachte Antriebs- und Steuereinheit und ein an der Oberseite des Modulgehäuses 6 angeordnetes und durch die Antriebs- und Steuereinheit u.a. um eine vertikale Maschinenachse des jeweiligen Moduls 4.1 - 4.8 umlaufend antreibbares Transport- und Behandlungselement 7, 7a mit einer Vielzahl von Aufnahmen 8, die am Umfang des Transport- und Behandlungselementes 7 bzw. 7a in gleichmäßigen Winkelabständen vereilt vorgesehen sind und von denen jede Aufnahme 8 zum gesicherten Aufnehmen jeweils eines Packmittels 2 ausgebildet ist.Each
Die Transport- und Behandlungselemente 7, 7a der einzelnen Module 4.1 - 8.1 sind unmittelbar bzw. transportmäßig an einander anschließend angeordnet und gegenläufig, aber synchron derart angetrieben, dass diese Transport- und Behandlungselemente 7, 7a in ihrer Gesamtheit eine Transporteinrichtung bilden, mit der die Packmittel 2 innerhalb der Vorrichtung 1 auf dem in der
Bei der Darstellung der
Bei der in den Figuren dargestellten Ausführungsform sind die einzelnen Module 4.1 - 4.8 weiterhin derart aufeinander folgend vorgesehen, dass die vertikalen Maschinenachsen sämtlicher Module 4.1 - 4.8 in einer gemeinsamen vertikalen Ebene liegen, in der sich auch die Übergabebereiche befinden, an denen die Packmittel 2 von dem Transport- und Behandlungselement 7a bzw. 7 eines Moduls 4.1 - 4.7 an das Transport- und Behandlungselement 7 bzw. 7a des in Transportrichtung A folgenden Moduls 4.2 - 4.8 weitergeleitet werden.In the embodiment shown in the figures, the individual modules 4.1 - 4.8 continue to be provided in such succession that the vertical machine axes of all modules 4.1 - 4.8 lie in a common vertical plane, in which the transfer areas are located, where the packaging means 2 of the transport and
Die prinzipielle und auch bekannte Funktion der einzelnen Module 4.1 - 4.8 ist beispielsweise folgende:
- Das Modul 4.1 bildet u.a. das Einlaufmodul bzw. den Packmitteleinlauf 1.1
der Vorrichtung 1. Im Modul 4.1 erfolgt vorzugsweise aber auch eine Vorbehandlung der Packmittel 2 zumindest an dem zu bedruckenden Packmittelbereich, beispielsweise eine Plasma- oder Koronabehandlung, die insbesondere dann zweckmäßig ist, wenn das Aufbringen des Mehrfachdrucks in den nachfolgenden Modulen unter Verwendung von dortigen Druckstationen oder Druckköpfen erfolgt, die nach dem bekannten Tintenstrahldruckkopfprinzip oder nach dem sogenannten Tonjet-Prinzip arbeiten. Weiterhin wir vorteilhafterweise im Modul 4.1 die Druckbeaufschlagung im Packmittel (2) erfolgen. - Die an das Modul 4.1 anschließenden Module 4.2 - 4.5 bildend die eigentlichen Druckmodule, in denen der Mehrfachdruck erfolgt, und zwar vorzugsweise als Farbdruck in der Form, dass an jedem Modul 4.2 - 4.5 jeweils ein Farbsatz des Farbdrucks gedruckt wird, beispielsweise in Gelb, Magenta, Zyan und Schwarz.
Die dortigen Aufnahmen 8 bilden also Behandlungs- oder Druckpositionen. - Das in Transportrichtung A dann anschließende Modul 4.6 ist z.B. als Trocknungsmodul ausgebildet, in welchem der jeweilige zuvor erzeugte Mehrfachdruck in geeigneter Weise, beispielsweise durch Energieeintrag z.B. durch Wärme und/oder durch UV-Strahlung endgültig getrocknet wird.
- Das Modul 4.7 ist als Inspektionsmodul ausgebildet, an welches jedes Packmittel 2 nach dem Trocknen des Mehrfachdrucks gelangt und in welchem der jeweilige Mehrfachdruck auf eventuelle Fehler überprüft wird, sodass fehlerhaft bedruckte Packmittel 2 an dem Modul 4.7 oder aber später auf dem weiteren Transportweg ausgeschleust werden können.
- Das Modul 4.8 bildet schließlich das Auslaufmodul bzw. den Packmittelauslauf 1.1
der Vorrichtung 1, an dem die fertig bedruckten Packmittel 2die Vorrichtung 1 verlassen. Das Modul 4.8 ist vorzugsweise zusätzlich auch noch als Trocknungsmodul ausgeführt.
- The module 4.1 forms, inter alia, the inlet module or the package inlet 1.1 of the
device 1. In the module 4.1 but preferably also a pretreatment of thepackaging 2 at least on the printed packaging area, for example a plasma or corona treatment, which is particularly useful if the Applying the multiple printing in the subsequent modules using local printing stations or printheads is done, which operate on the well-known inkjet printhead principle or the so-called Tonjet principle. Furthermore, we advantageously in the module 4.1, the pressurization in the packaging (2). - The modules 4.2 - 4.5 following the module 4.1 form the actual printing modules in which the multiple printing takes place, preferably as color printing in the form that a color set of the color print is printed on each module 4.2 - 4.5, for example in yellow, magenta , Cyan and black. The
local recordings 8 thus form treatment or printing positions. - The then in the transport direction A then module 4.6 is formed, for example, as a drying module, in which the respective previously generated Multiple printing in a suitable manner, for example by energy input, for example, by heat and / or by UV radiation is finally dried.
- The module 4.7 is designed as an inspection module to which each
packaging 2 passes after drying the multiple pressure and in which the respective multiple print is checked for any errors, so that incorrectly printedpackaging 2 can be discharged to the module 4.7 or later on the further transport , - Finally, the module 4.8 forms the outlet module or the package outlet 1.1 of the
device 1, on which the finished printedpackaging 2 leaves thedevice 1. The module 4.8 is preferably also additionally designed as a drying module.
Wie insbesondere die
Mehr im Detail bestehen die Module 4.1 - 4.n, zumindest aber die zum Bedrucken der Packmittel 2 dienenden Module 4.2 - 4.7 bzw. deren umlaufende Transport- und Behandlungselement 7 aus mehreren Drucksegmenten 11, die jeweils als komplette funktionsfähige Baueinheiten an einem um die jeweilige vertikale Maschinenachse MA umlaufend angetriebenen Rotor 12 austauschbar montiert sind, welch letzterer an dem jeweiligen Modulgehäuse 6 bzw. an einer zentralen Tragsäule 13 um die vertikale Maschinenachse MA drehbar gelagert ist. Die am Umfang des Rotors 12 vorgesehenen und in Umfangsrichtung des Rotors 12 aneinander anschließenden und in Draufsicht keilartig ausgebildeten Drucksegmenten 11 bilden innen liegend, d.h. im Bereich der Maschinenachse MA einen von den Drucksegmenten 11 umschlossenen Raum, in welchem verschiedene Funktionselemente, so z.B. u.a. auch elektronische Steuerelemente oder Rechner 14 (
Die Drucksegmente 11 bilden an ihrer bezogen auf die Maschinenachse MA radial außen liegenden Seite jeweils eine Ausnehmung 15, siehe auch
Die Halte- und Zentriereinheiten 16 sind ihrerseits jeweils an einem Träger 17 gehalten, der in der zugehörigen seitlichen Nuten 18 befestigt ist. Optional kann der Träger 17 schlittenartig in den Nuten 18 verfahren oder verschoben werden, ggf. motorisch angetrieben (
Die Funktion des Sekundärteils 20 besteht u.a. darin, das jeweilige Packmittel 2 hängend zu halten. Das Sekundärteil 20 ist hierfür greiferartig ausgebildet, beispielsweise als mechanischer und/oder pneumatisch betätigter Greifer und/oder als Vakuumgreifer. Idealerweise wird in dem jeweiligen Drucksegment 11 die erforderliche Haltekraft auf das Primärteil 19 passiv aufgebracht und aktiv weggenommen bzw. gelöst, um die Sicherheit bei Strom- bzw. Medienlosigkeit zu erhöhen, zum Beispiel durch einen oder mehrere Permanentmagnete.The function of the
Das Sekundärteil 20 umfasst die aktiven Komponenten, d.h. insbesondere sämtliche für das Ausrichten und gesteuerte Drehen bzw. Schwenken der Packmittel 2 während der Behandlung notwendigen Komponenten, so u.a. Elemente, die zum Ausrichten und/oder Drehen der Packmittel beim Bedrucken erforderlich sind. und/oder die Elemente zum Zuführen von Druckluft und/oder Vakuum usw.The
So bildet das in dem Primärteil 19 um die Drucksegmentachse DA dreh- oder schwenkbar gelagerte Sekundärteil 20 bei der dargestellten Ausführungsform den Rotor eines elektrischen Stell- oder Winkelantriebs für das Ausrichten und gesteuerte Drehen bzw. Schwenken der Packmittel 2 während der Behandlung. Das Sekundärteil 20 ist hierfür u.a. mit einer Permanentmagnetanordnung 21 versehen, die eine Vielzahl von Permanentmagneten aufweist. Die Permanentmagnetanordnung 21, die in einer Umfangsrichtung abwechselnd magnetische Nord- und Südpole aufweist, wirkt hierfür mit einer am Träger 17 vorgesehenen Elektromagnetanordnung 22 zusammen, die den Stator des Stellantriebes bzw. des elektromagnetischen Direktantriebes bildet.Thus, in the illustrated embodiment, the
Am Primärteil 19 ist eine Kodierung 23 vorgesehen, die im Zusammenwirken mit einem am Träger 17 vorgesehenen Inkrementalsensor 24 ein Encoder-System bildet, mit dem die jeweilige zufällige Orientierung des Primärteils 19 und damit der Halte- und Zentriereinheit 16 erfasst wird. Das Ausrichten und/oder gesteuerte Drehen der Packmittel 2 beim Drucken erfolgt dann unter Berücksichtigung dieser vom Encoder-System festgestellten Orientierung und der aus der Konstruktion bekannten oder festgelegten Zuordnung zwischen Primärteil 19 und Drehstellung des Sekundärteils 20, und zwar ausschließlich durch Drehen des Sekundärteils 20 bei nicht drehendem Primärteil 19. Der Inkrementalsensor 24 ist relativ zum Rotor 12 bzw. der Tragsäule 13 ortsfest und läuft mit diesen um. Das Ausrichten und gesteuerte Drehen der Packmittel 2 um die Achse DA erfolgt jeweils in Bezug auf das jeweilige Drucksegment 11 bzw. in Bezug auf dortige, für die Behandlung dienende Funktionselemente, insbesondere Druckköpfe.On the
Die
In dem Sekundärteil 20 ist ein Zentrier- und Halteelement 28 bezogen auf die Achse DA axial verschiebbar angeordnet. Das Zentrier- und Halteelement 28 besteht bei der dargestellten Ausführungsform aus einem äußeren Hülsenkörper 29, der mittels einer Druckfeder 30 in eine untere Stellung vorgespannt ist, in der der Hülsenkörper 29 mit seiner unteren Stirnfläche gegen die Tragplatte 26 und bei an der Halte- und Zentriereinheit 16 gehaltenem Packmittel 2 in Form einer Flasche gegen die der Tragplatte 26 abgewandte Oberseite des Packmittels 2 bzw. gegen den dortigen Mündungsrand 2.2 des Packmittels 2 anliegt, sodass dieses durch die Kraft der Druckfeder 30 zwischen dem Hülsenkörper 29 und der Tragplatte 26 fest, insbesondere auch verdrehungssicher eingespannt ist. In dem Hülsenkörper 29 ist eine ebenfalls achsgleich mit der Achse DA angeordnete Zentrierhülse 31 axial beweglich vorgesehen. Letztere ist durch eine Druckfeder 32 ebenfalls in eine untere Stellung vorgespannt.In the
Zum Aufnehmen eines Packmittels 2 bzw. einer Flasche wird das von dem Hülsenkörper 29, der Druckfeder 30, der Zentrierhülse 31 und der Druckfeder 32 gebildetes Zentrier- und Halteelement 29 gegen die Wirkung insbesondere der Druckfeder 30 angehoben (Schritt 1), und zwar durch ein einen Bund oder eine Ringnut 33 des Hülsenkörpers 29 hintergreifendes Hubelement, welches zumindest am Packmitteleinlauf 1.1 und am Packmittelauslauf 1.2 vorgesehen ist, wie in
Bei alternativen nicht dargestellten Ausführungsformen sind natürlich andere Antriebe für das Einspannen der Packmittel denkbar, wie zum Beispiel pneumatisch oder elektrische angetriebene Greif- und/oder Spannelemente.In alternative embodiments, not shown, of course, other drives for clamping the packaging conceivable, such as pneumatic or electric driven gripping and / or clamping elements.
Die Packmittel 2 sind mit ihrem Mündungsbereich zwischen dem Mündungsflansch 2.1 und dem Mündungsrand 2.2 in dem Innenraum 25.1 der Hülse 25 geschützt aufgenommen. Insbesondere bei einer sehr hygienischen Ausführung ist es vorteilhaft, die Halte- und Zentriereinheiten 16, bzw. deren Sekundärteile 20 so auszubilden, dass der Mündungsbereich und ein dortiges Gewinde die Mündung 2.2 eines jeden Packmittels 2 während des Bedruckungsvorgang vor Verschmutzung, insbesondere Tintennebel, geschützt sind.The packaging means 2 are taken protected with their mouth region between the mouth flange 2.1 and the mouth edge 2.2 in the interior 25.1 of the
Zur Stabilisierung der noch leeren Packmittel 2 ist es dabei zweckmäßig, diese beim oder nach dem Fixieren an der jeweiligen Halte- und Zentriereinheit 16 mit einem unter Druck stehenden gas- und/oder dampfförmigen Medium, beispielsweise mit Druckluft zu beaufschlagen. Wie in
Bevorzugt ist das Sekundärteil 20 so ausgebildet, dass das formatabhängige Aufnahme- und Fußteil 20.1 lösbar mit dem Sekundärteil 20 verbunden ist, sodass zur Verarbeitung von Packmitteln 2 unterschiedlicher Art und/oder Form und/oder Größe die Aufnahme- und Fußteile 20.1 an den Halte- und Zentriereinheiten 16 gegen jeweils passende ausgetauscht werden können. Die an die Art und/oder Form und/oder Größe der zu behandelnden Packmittel 2 angepassten Aufnahme- und Fußteile 20.1 sind dann verdrehungssicher, beispielsweise mit Hilfe eines Schnellwechselmechanismus oder einer Schnellkupplung oder einer herkömmlichen Schraub- und/oder Klemmbefestigung mit dem Sekundärteil 20 verbunden.The
Die
Die Halte- und Zentriereinheiten 16 und dabei bevorzugt die Sekundärteile 20 dieser Einheiten sind weiterhin mit einer eindeutigen Identifikationsmöglichkeit, vorzugsweise mit einer mit einer RFID-Kennung versehen, die die Identifizierung der jeweiligen Halte- und Zentriereinheit 16, und dabei insbesondere eine Information über die Art dieser Einheit und/oder des Sekundärteils 20 enthält. Die entsprechenden Informationen können dann von wenigstens einer Leseeinheit der Vorrichtung 1 und/oder des jeweiligen Druckmoduls 4.1 - 4.n ausgelesen werden, beispielsweise für Überwachungs- oder Kontrollzwecke.The holding and centering

Die Drucksegmente 11a sind wieder an einander anschließend auf dem Rotor 12 vorgesehen, der seinerseits um die vertikale Maschinenachse MA drehbar und antreibbar an der Tragsäule 13 der Grundeinheit 5entsprechenden Grundeinheit 5a gelagert ist.The
Jedes Drucksegment 11a weist wiederum im Inneren seines segmentartigen Gehäuses 11a.1 die zum Bedrucken der Packmittel 2 notwendigen Funktionselemente auf, so u.a. wenigstens einen Druckkopf 35, der beispielsweise ein nach dem Ink-Jet-Verfahren arbeitender Druckkopf ist, welcher u.a. elektronisch steuerbaren Austrittsdüsen für Druckfarbe oder -tinte sowie sonstige Medien aufweist, die in wenigstens einer Reihe parallel zur Achse DA angeordnet sind. Jedem Druckkopf 35 ist eine Einrichtung 36 zum sofortigen Trocknen der auf das Packmittel 2 ausgebrachten Druckfarbe bzw. des entsprechenden Druckbildes zugeordnet. Bei der dargestellten Ausführungsform ist die Einrichtung 36 ein Infrarot- und/oder ein UV-Strahler zur Abgabe einer bandförmigen UV- und/oder Infrarot-Strahlung 37, die zumindest das gesamte, mit dem Druckkopf 35 aufgebrachte Druckbild erfasst. Die Einrichtung 36 ist gegenüber dem Druckkopf 35 bezogen auf die Achse DA um einen Winkelbetrag versetzt vorgesehen. Beim Bedrucken des Packmittels 2 wird dieses um die Achse DA derart gesteuert gedreht, dass die mit dem Druckkopf 35 ausgebrachte Druckfarbe unmittelbar nach dem Ausbringen mit der UV- und/oder Infrarot-Strahlung 37 getrocknet oder zumindest weitestgehend getrocknet wird.Each
In nicht näher dargestellter Weise wird die Einrichtung 36 gekühlt, beispielsweise unter Verwendung von Luft- und/oder Wasser als Kühlmedium.In a manner not shown, the
Der Druckkopf 35, die Einrichtung 36 sowie auch eine zumindest als Treiberstufe für den Druckkopf 35 ausgebildete Elektronik 38 sind an einem gemeinsamen Schlitten 39 vorgesehen, der an einer Tragsäule 40 mittels eines Stellantriebs 41 in Richtung der Achse DA verstellbar geführt ist.
