Description

Die Erfindung betrifft eine Vorrichtung zum Heißfolienprägen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for hot foil stamping according to the preamble of claim 1.

Stand der TechnikState of the art

Zu den bekannten Veredelungsarten in der Druckindustrie gehört unter anderem das sogenannte Heißfolienprägen.One of the known types of finishing in the printing industry is the so-called hot foil stamping.

Spiegelglatte Flächenelemente in Gold, Silber, Kupfer, Aluminium und anderen Metallic-Farben lassen sich im Heißfolienprägedruck auf den Bedruckstoff übertragen. Eine Trägerfolie wird mit der farbgebenden Schicht und einem heißschmelzendem Kleber (Haftschicht) beschichtet. Unter Druck und Wärme kann mit einem beheizten Klischee (Hochdruckform) das Bild übertragen werden. Geeignete Maschinen sind entweder rotative Bearbeitungsstationen in Druckmaschinen oder Flachbettstanz- und/oder -Prägemaschinen. Die Heißfolienprägung wird vorrangig in vielfältigen Bogen- und Rollenprodukten, wie Verpackungen für Kosmetika, Süßwaren und Getränke sowie für hochwertige Broschüren eingesetzt.Mirror-smooth surface elements in gold, silver, copper, aluminum and other metallic colors can be transferred to the substrate in hot foil stamping. A carrier film is coated with the coloring layer and a hot-melt adhesive (adhesive layer). Under pressure and heat, the image can be transferred with a heated cliché (high-pressure mold). Suitable machines are either rotary processing stations in printing machines or flat bed punching and / or embossing machines. Hot foil stamping is primarily used in a wide range of sheetfed and roll products, such as packaging for cosmetics, confectionery and beverages, as well as for high-quality brochures.

In der DE 10 2009 019 590 A1 wird eine rotative Heißfolienprägestation beschrieben und in ihrer Figur 8 dargestellt.In the DE 10 2009 019 590 A1 a rotary hot foil stamping station is described and shown in its FIG.

Nachteilig bei derartigen Vorrichtungen zum Heißfolienprägen ist der hohe Kosten- und Zeitaufwand für die Herstellung der Werkzeuge, das heißt der Prägeklischees für einen jeweiligen Auftrag.A disadvantage of such devices for hot foil stamping is the high cost and time required for the production of tools, that is the embossing dies for a particular order.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Heißfolienprägen zu schaffen, welche die Nachteile des Standes der Technik nicht aufweist und ein Heißfolienprägen in nur einer Bearbeitungsstation ohne teure auftragsindividuelle Prägewerkzeuge ermöglicht.The object of the present invention is therefore to provide a device for hot foil stamping which does not have the disadvantages of the prior art and enables hot foil stamping in only one processing station without expensive, job-specific stamping tools.

Gelöst wird diese Aufgabe durch eine Vorrichtung zum Heißfolienprägen mit den Merkmalen von Anspruch 1. Die erfindungsgemäße Vorrichtung zum Heißfolienprägen auf Bedruckstoffe, wie Bogen oder Bahnen, insbesondere aus Papier, Karton oder Kunststoff, besitzt ein Prägeelement, ein diesem Prägeelement zugeordnetes Gegenprägeelement und eine Einrichtung zur Bereitstellung von Prägefolie. Erfindungsgemäß besitzt die Vorrichtung eine Lasereinheit zum partiellen Erhitzen von Prägefolie im Bereich des Prägeelements, wobei das Prägeelement transparent ausgeführt ist, derart, dass die Laserstrahlen der Lasereinheit das Prägeelement durchdringen und die Prägefolie an den gewünschten Stellen partiell erhitzt wird. Vorteilhaft an dieser Vorrichtung ist, dass keine Werkzeuge auftragsspezifisch erstellt werden müssen. Damit ist ein Motivwechsel der Heißfolienprägung innerhalb kürzester Zeit möglich. Das heißt, ein Motiv kann auch während der laufenden Produktion umgestellt werden. Durch das direkte Erhitzen der Prägefolie wird sichergestellt, dass das heißfoliengeprägte Motiv eine hohe Randschärfe aufweist.This object is achieved by a device for hot foil stamping with the features of claim 1. The inventive device for hot foil stamping on substrates, such as sheets or sheets, in particular of paper, cardboard or plastic, has an embossing element, this embossing element associated counter-embossing element and means for Provision of stamping foil. According to the invention, the device has a laser unit for partially heating embossing foil in the region of the embossing element, wherein the embossing element is transparent, such that the laser beams of the laser unit penetrate the embossing element and the embossing foil is partially heated at the desired locations. An advantage of this device is that no tools must be created job specific. This makes it possible to change the motif of the hot foil stamping within a very short time. This means that a motif can also be changed during production. The direct heating of the embossing foil ensures that the hot foil embossed motif has a high edge definition.

Die erfindungsgemäße Vorrichtung besitzt eine Steuereinheit zumindest zur Ansteuerung der Lasereinheit. Es ist zusätzlich ein mit der Steuereinheit datenübertragungstechnisch verbundener Sensor zur Überwachung des Bedruckstoffes vorgesehen, so dass eine passergenaue Ansteuerung der Lasereinheit erreicht werden kann. So kann die Heißfolienprägung passergenau zu einem bereits vorher gedruckten Druckbild auf den Bedruckstoff aufgebracht werden.The device according to the invention has a control unit at least for controlling the laser unit. In addition, a data transmission technology-related sensor for monitoring the printing material is provided with the control unit, so that accurate register control of the laser unit can be achieved. Thus, the hot foil stamping can be applied to the substrate in register with an already pre-printed print image.

In vorteilhafter Weiterbildung der erfindungsgemäßen Vorrichtung ist das Prägeelement aus Glas. Das Gegenprägeelement kann eine gummierte Oberfläche aufweisen.In an advantageous embodiment of the device according to the invention, the embossing element is made of glass. The counter-embossing element may have a rubberized surface.

In einer ersten Ausführungsvariante sind Prägeelement und Gegenprägeelement jeweils als Zylinder ausgeführt, in einer zweiten Ausführungsvariante sind Prägeelement und Gegenprägeelement jeweils als Platte ausgeführt.In a first embodiment, embossing element and counter-embossing element are each designed as a cylinder, in a second embodiment, embossing element and counter-embossing element are each designed as a plate.

Bei der ersten Ausführungsvariante kann angrenzend an den Prägezylinder eine Kühleinrichtung vorgesehen sein.In the first embodiment, a cooling device may be provided adjacent to the embossing cylinder.

Figur 3 zeigt als Beispiel einer Verarbeitungsmaschine 100 eine Rotationsdruckmaschine zum Bedrucken einer Substratbahn 1. Die Substratbahn 1 wird dabei in Transportrichtung T durch eine Mehrzahl von Bearbeitungswerken hindurch transportiert und dabei bearbeitet. Bei den Bearbeitungswerken handelt es sich um konventionelle Druckwerke 11, ein Digitaldruckwerk 14, ein Prägewerk 12 und ein Stanz- und Rillwerk 13. Angrenzend an den Bahnlauf der Substratbahn 1 kann ein (oder auch mehrere) Inspektionssystem 4 vorgesehen sein, welches beispielsweise als Kamera ausgeführt ist, um kontinuierlich die Substratbahn 1 zu überwachen. FIG. 3 shows as an example of a processing machine 100, a rotary printing press for printing a substrate web 1. The substrate web 1 is thereby in the transport direction T transported through a plurality of processing plants and edited it. The processing units are conventional printing units 11, a digital printing unit 14, an embossing unit 12 and a stamping and creasing unit 13. Adjacent to the web run of the substrate web 1, one (or more) inspection system 4 can be provided, which is designed, for example, as a camera is to continuously monitor the substrate web 1.

Anstelle des konventionellen Prägewerks 12 kann eine Vorrichtung zum Heißfolienprägen 10, wie nachfolgend beschrieben, zum Einsatz gelangen.Instead of the conventional stamping mill 12, a device for hot foil stamping 10, as described below, can be used.

Besonders vorteilhaft ist der Einsatz einer solchen Vorrichtung zum Heißfolienprägen 10 in Bearbeitungsmaschinen 100, welche ausschließlich digitale Bearbeitungsstationen aufweisen.Particularly advantageous is the use of such a device for hot foil stamping 10 in processing machines 100, which have exclusively digital processing stations.

Figur 1 zeigt eine erste Ausführungsvariante der Vorrichtung zum Heißfolienprägen 10, welche als Bearbeitungswerkzeuge Zylinder vorsieht: Die Vorrichtung 10 besitzt einen transparenten Zylinder 21 und einen Gegendruckzylinder 16. Der Gegendruckzylinder 16 kann dabei gummiert ausgeführt sein. Im Druckspalt zwischen dem transparenten Zylinder 21, beispielsweise ausgeführt als Glaszylinder, und dem Gegendruckzylinder 16 wird sowohl eine Substratbahn 1 als auch eine Folie 2 hindurch geführt. Bereitstellung und Führung der Folienbahn 2 erfolgt durch eine nicht näher dargestellte, Transportrollen aufweisende Einrichtung zur Bereitstellung von Prägefolie. Innerhalb des transparenten Zylinders 21 ist eine Lasereinheit 19 angeordnet, welche von einer Steuereinheit 3 (hier nicht dargestellt) angesteuert wird. Die von der Lasereinheit 19 ausgesandten Laserstrahlen 20 durchdringen den transparenten Zylinder 21 und erhitzen gezielt und lokal die Folie 2. An dieser lokal erhitzten Stelle können sodann Metallpartikel von der Trägerfolie 2 auf die Substratbahn 1 übertragen werden und werden aufgrund der Anpresskraft F zwischen transparentem Zylinder 21 und Gegendruckzylinder 16 auf die Substratbahn 1 "aufgebügelt", wodurch die Heißfolienprägung erzeugt wird. FIG. 1 shows a first embodiment of the apparatus for hot foil stamping 10, which provides cylinders as processing tools: The apparatus 10 has a transparent cylinder 21 and a counter-pressure cylinder 16. The impression cylinder 16 may be performed gummed. In the nip between the transparent cylinder 21, for example, designed as a glass cylinder, and the impression cylinder 16, both a substrate web 1 and a film 2 is guided through. Provision and guidance of the film web 2 is effected by a device, not shown, having transport rollers for providing embossing film. Within the transparent cylinder 21, a laser unit 19 is arranged, which is controlled by a control unit 3 (not shown here). The laser beams 20 emitted by the laser unit 19 penetrate the transparent cylinder 21 and heat the film 2 selectively and locally. Metal particles can then be transferred from the carrier film 2 to the substrate web 1 at this locally heated point and become transparent between the transparent cylinder 21 due to the contact force F and impression cylinder 16 "ironed" on the substrate web 1, whereby the hot foil stamping is produced.

In Figur 2 ist eine alternative Ausführungsform der Vorrichtung zum Heißfolienprägen 10 dargestellt. Anstelle der Zylinder werden hierbei Platten verwendet, nämlich eine transparente Platte 22 als Prägeelement, welche ausgeführt sein kann als Glasplatte, und eine Gegendruckplatte 23 als Gegenprägeelement. Auch hier kann die Gegendruckplatte 23 eine gummierte Oberfläche aufweisen.In FIG. 2 an alternative embodiment of the hot foil stamping apparatus 10 is shown. Instead of the cylinder plates are used here, namely a transparent plate 22 as an embossing element, which may be designed as a glass plate, and a counter-pressure plate 23 as a counter-embossing element. Again, the platen 23 may have a rubberized surface.

Während die mit Zylindern 16, 19 versehene Variante gemäß Figur 1 eine kontinuierliche Bearbeitung eines Bedruckstoffs 1 ermöglicht, kann mit der Ausführungsvariante gemäße Figur 2 mit den Platten 22, 23 nur eine diskontinuierliche Bearbeitung des Bedruckstoffs 1 erreicht werden. Das heißt, für jeden Prägeprozess muss der Bedruckstoff 1 kurzzeitig angehalten werden.While provided with cylinders 16, 19 variant according to FIG. 1 enables continuous processing of a printing material 1, can with the embodiment according to FIG. 2 With the plates 22, 23 only a discontinuous processing of the printing material 1 can be achieved. This means that for each embossing process the substrate 1 has to be stopped for a short time.
