Description

Die vorliegende Erfindung betrifft eine Vorrichtung sowie ein Verfahren zur multifunktionalen Folienprägung. Insbesondere betrifft die vorliegende Erfindung eine Vorrichtung sowie ein Verfahren zur multifunktionalen Prägung von Versiegelungsfolien für Verpackungen.The present invention relates to a device and a method for multifunctional foil stamping. In particular, the present invention relates to a device and a method for the multifunctional embossing of sealing films for packaging.

Versiegelungsfolien werden in der Verpackungsindustrie für eine Vielzahl unterschiedlicher Produkte verwendet, beispielsweise als Verschluss für entsprechende Verpackungsbehälter wie Becher oder Boxen. Dabei werden die Versiegelungsfolien oftmals durch Ausstanzen entsprechender Formen aus einem bandförmigen Material erhalten. Bei dem dabei verwendeten Material kann es sich beispielsweise um Aluminiumfolie, Kunststofffolie, oder Verbundmaterialien aus Kunststoff und Aluminium handeln. Oftmals ist das Material dabei zumindest einseitig oder beidseitig bedruckt. Zum Verschluss von Verpackungsbehältern werden die Versiegelungsfolien auf die Behälter aufgeklebt oder aufgeschweißt. Hierzu können die Folien auf der dem Verpackungsbehälter zugewandten Seite beispielsweise eine Heißsiegellackschicht aufweisen.Sealing foils are used in the packaging industry for a large number of different products, for example as a closure for corresponding packaging containers such as cups or boxes. The sealing films are often obtained by punching out corresponding shapes from a strip-shaped material. The material used here can be, for example, aluminum foil, plastic foil, or composite materials made of plastic and aluminum. Often the material is printed on at least one or both sides. In order to close packaging containers, the sealing films are glued or welded onto the container. For this purpose, the foils can have, for example, a heat-sealing lacquer layer on the side facing the packaging container.

Nach dem Ausstanzen einer der zu verschließenden Öffnung des Verpackungsbehälter entsprechenden Form aus dem Bandmaterial werden die erhaltenen Formstücke in der Regel gestapelt. Zum Verschießen der Verpackungsbehälter werden die z.B. als Deckel vorgesehenen Formstücke dem Stapel mit geeigneten Greifsystemen, wie beispielsweise Vakuumgreifern, entnommen und auf der zu verschließenden Öffnung des Verpackungsbehälters angeordnet. In Abhängigkeit des benutzten Klebesystems, wie z.B. Heißsiegellack, werden die als Deckel vorgesehenen Formstücke dann unter Einwirkung von Druck und/oder Wärme mit dem Verpackungsbehälter verbunden.After a shape corresponding to the opening of the packaging container to be closed has been punched out of the strip material, the molded pieces obtained are usually stacked. To close the packaging containers, the shaped pieces, for example, provided as lids, are removed from the stack with suitable gripping systems, such as vacuum grippers, and placed on the opening of the packaging container to be closed. Depending on the adhesive system used, such as heat seal lacquer, the molded pieces provided as lids are then connected to the packaging container under the action of pressure and / or heat.

Zur Vermeidung, dass beim Abheben der Formstücke vom Stapel mehrere Formstücke aneinanderhaften ist es aus dem Stand der Technik bekannt, die Formstücke im Randbereich mit einer Prägung zu versehen, durch welche ein Aneinanderhaften der einzelnen Formstücke vermieden wird. Weitere Zwecke erfüllt eine solche Prägung nicht.In order to avoid a number of fittings sticking together when the fittings are lifted from the stack, it is known from the prior art to place the fittings in the edge area to be provided with an embossing, which prevents the individual fittings from sticking to one another. Such imprinting does not serve any other purposes.

Vorrichtungen und Verfahren zur Prägung von Versiegelungsfolien sind aus dem Stand der Technik bekannt. So offenbart beispielsweise die EP 0 960 024 B2 ein Verfahren zur Herstellung von teilweise geprägten Deckelelementen für den Verschluss von Behältern, insbesondere Nahrungsmittelbehältern sowie eine Vorrichtung zur Durchführung dieses Verfahrens.Devices and methods for embossing sealing films are known from the prior art. For example, the EP 0 960 024 B2 a method for the production of partially embossed cover elements for the closure of containers, in particular food containers, and a device for carrying out this method.

Ebenso offenbart die EP 1 790 470 B1 ein Verfahren zur Herstellung von partiell mit Prägungen versehenen und zusätzlich bedruckten aufsiegelbaren Verpackungsdeckeln oder Etiketten.Likewise reveals the EP 1 790 470 B1 a process for the production of partially embossed and additionally printed sealable packaging lids or labels.

WO 2016/118990 A1 offenbart eine Prägevorrichtung gemäß dem Oberbegriff von Anspruch 1. WO 2016/118990 A1 discloses an embossing device according to the preamble of claim 1.

DE 10 2009 003 493 A1 offenbart einen Artikelstempel mit einem Gehäuse, wenigstens einem in das Gehäuse eingesetzten auswechselbaren Buchstaben, einem Riegel, mittels welchem der Buchstabe formschlüssig in dem Gehäuse verriegelt ist, wobei der mittels wenigstens einer Feder in seiner den Buchstaben verriegelnden Position gehaltene Riegel gegen die Kraft der Feder in eine den Buchstaben freigebende Position bewegt werden kann. DE 10 2009 003 493 A1 discloses an article stamp with a housing, at least one replaceable letter inserted into the housing, a bolt by means of which the letter is positively locked in the housing, the bolt held by at least one spring in its position locking the letter against the force of the spring a position releasing the letter can be moved.

EP 2 857 187 A1 offenbart ein Verfahren gemäß dem Oberbegriff von Anspruch 4. EP 2 857 187 A1 discloses a method according to the preamble of claim 4.

Ein Nachteil der aus dem Stand der Technik bekannten Verfahren und Vorrichtungen ist es, dass eine zur Trennung der Formstücke (Deckel) eingesetzte Prägung sich bei Verkleben und/oder Verschweißen gegebenenfalls nachteilig auf die Haftung zwischen Verpackungsbehälter und Formstück auswirkt.A disadvantage of the methods and devices known from the prior art is that an embossing used to separate the molded pieces (cover) may have a detrimental effect on the adhesion between the packaging container and the molded piece during gluing and / or welding.

Ein weiterer Nachteil der aus dem Stand der Technik bekannten Systeme ist es, dass es zum Wechsel des Prägemusters notwendig ist, dass gesamte Prägewerkzeug, bei dem es sich üblicher Weise um eine Prägematrize ggf. in Kombination mit einer Prägepatrize handelt, ausgetauscht werden muss, was einerseits mit einem erhöhten Zeitaufwand, andererseits mit einem erhöhten Kostenaufwand einhergeht.Another disadvantage of the systems known from the prior art is that to change the embossing pattern it is necessary that the entire embossing tool, which is usually an embossing die, possibly in combination with an embossing die, has to be replaced on the one hand with an increased expenditure of time, on the other hand with an increased expenditure.

Vor diesem Hintergrund ist es die Aufgabe der vorliegenden Erfindung eine Vorrichtung sowie ein Verfahren anzugeben, mit welchen in einfacher Weise eine multifunktionale Folienprägung ermöglicht wird.Against this background, the object of the present invention is to specify a device and a method with which multifunctional foil stamping is made possible in a simple manner.

Gelöst wird diese Aufgabe durch eine Vorrichtung gemäß Anspruch 1 sowie ein Verfahren gemäß unabhängigen Anspruch 4.This object is achieved by a device according to claim 1 and a method according to independent claim 4.

Mit der Erfindung wird Vorrichtung zur multifunktionalen Prägung von Folien vorgeschlagen, welche ein Grundprägeelement, eine Aufnahmebereich, sowie ein innerhalb des Aufnahmebereichs lösbar angeordnetes Wechselprägeelement aufweist, wobei das lösbar angeordneten Wechselprägeelemente ein eine haptisch wahrnehmbare Information vermittelndes Prägebild aufweist.The invention proposes a device for the multifunctional embossing of foils which has a basic embossing element, a receiving area, and an alternating embossing element which is detachably arranged within the receiving area, this being detachable arranged alternating embossing elements has a haptically perceptible information conveying embossed image.

Durch das vorsehen eines Prägebildes mit einer haptisch wahrnehmbaren Information wird die so erzeugte Prägung in vorteilhafter Weise multifunktionalisiert, so dass die erzeugte Prägung zum einer zur Informationswahrnehmung zum anderen zur Vereinzelung bei der Abstapelung von gestanzten Versiegelungsfolien dient. Hierdurch kann beispielsweise auf das vorsehen eines Prägemusters im Bereich des Versiegelungsrandes des Versiegelungsfolie verzichtet werden, um so eine optimierte Versiegelung beim aufbringen des Versiegelungsfolie auf die Verpackung sicherzustellen.By providing an embossed image with haptically perceptible information, the embossing produced in this way is advantageously multifunctional, so that the embossing produced is used on the one hand for information perception and on the other hand for separation when stacking stamped sealing foils. In this way, for example, the provision of an embossed pattern in the area of the sealing edge of the sealing film can be dispensed with in order to ensure an optimized seal when the sealing film is applied to the packaging.

Insbesondere kann durch die so vorgesehene multifunktionalisierte Prägung eine Versiegelungsfolie für Verpackungen bereitgestellt werden, welche es sehbeeinträchtigten Personen ermöglicht, in vereinfachter Weise Informationen über den Inhalt des in der Verpackung befindlichen Produktes zu erhalten. Solche Informationen wurden bisher nur auf Umverpackungskartonagen, wie beispielsweise Arzneimittelumverpackungen bereitgestellt. Der Verlust der Umverpackung führt dabei jedoch auch zum Verlust der haptisch wahrnehmbaren Informationen.In particular, the multifunctional embossing provided in this way can provide a sealing film for packaging which enables visually impaired people to obtain information about the content of the product in the packaging in a simplified manner. Until now, such information has only been provided on outer packaging cardboard, such as pharmaceutical outer packaging. However, the loss of the outer packaging also leads to the loss of the haptically perceptible information.

Gemäß der Erfindung weist die Vorrichtung Fixiermittel zur lösbaren Festlegung des Wechselprägeelementes aufweist. Hierdurch ist ein einfacher Wechsel des Wechselprägeelementes und somit ein einfacher Austausch der mit dem Wechselprägeelement bereitgestellten haptisch Wahrnehmbaren Information möglich. Als Fixiermittel sind dabei insbesondere solche Elemente geeignet, welche eine kraftschlüssige und/oder formschlüssige Festlegung des Wechselprägeelementes am Grundprägeelement ermöglichen, wie beispielsweise Schraubklemmelemente oder Verschraubungen.According to the invention, the device has fixing means for releasably fixing the exchangeable embossing element. As a result, a simple change of the exchangeable embossing element and thus a simple exchange of the haptically perceptible information provided with the exchangeable embossing element is possible. Particularly suitable as fixing means are those elements which enable a non-positive and / or positive fixing of the interchangeable embossed element on the basic embossed element, such as screw clamping elements or screw connections.

Gemäß der Erfindung weist die Vorrichtung einen Aufnahmebereich auf, welcher zur Aufnahme eine Mehrzahl von Wechselprägeelementen ausgelegt ist. Hierdurch können beispielsweise mehrere Braille-Zeichen oder Piktogramme in Wahrnehmungsrichtung hintereinander angeordnet werden, wodurch der vermittelte Informationsgehalt erhöht werden kann.According to the invention, the device has a receiving area which is designed to receive a plurality of alternating embossing elements. This allows, for example, several Braille characters or pictograms in the direction of perception be arranged one behind the other, whereby the conveyed information content can be increased.

Insbesondere weist das Grundprägeelement mehrere Aufnahmebereiche für Wechselprägeelemente auf.In particular, the basic embossed element has several receiving areas for alternate embossed elements.

Gemäß der Erfindung sind das Grundprägeelement und das Wechselprägeelement als Matrize ausgebildet und die Vorrichtung weist eine hinsichtlich des Prägebildes des Grundprägeelementes invertierte Grundpatrize auf, welche einen Aufnahmebereich sowie ein innerhalb eines Aufnahmebereichs lösbar angeordnetes Wechselpatrizenelement aufweist. Das Wechselpatrzienelement weist dabei ein hinsichtlich des Prägebildes des Wechselprägeelementes invertiertes Prägebild auf. Bevorzugt sind dabei Grundprägeelement und die Grundpatrize zueinander ausrichtbar angeordnet.According to the invention, the base embossing element and the interchangeable embossing element are designed as a die and the device has a base male which is inverted with regard to the embossing pattern of the base embossing element and which has a receiving area and an interchangeable male element detachably arranged within a receiving area. The interchangeable cartridge element has an embossed image that is inverted with respect to the embossed pattern of the interchangeable embossed element. The base embossing element and the base male are preferably arranged so that they can be aligned with one another.

Gemäß der Erfindung weist diese eine Prägeplatte auf, welche eine Mehrzahl von Grundprägeelementen umfasst. Sofern eine Patrize vorgesehen ist weist die Vorrichtung dem entsprechend eine Patrizenplatte auf, welche eine Mehrzahl von Grundpatrizen (210) umfasst. Hierdurch ist es möglich, in einem Prägezug eine Mehrzahl Deckelfolie zu prägen.According to the invention, this has an embossing plate which comprises a plurality of basic embossing elements. If a male mold is provided, the device accordingly has a male mold plate which comprises a plurality of base male parts (210). This makes it possible to emboss a plurality of cover sheets in one embossing train.

Gemäß der Erfindung ist es vorgesehen, dass die Wechselprägeelemente und/oder Wechselpatrizenelemente derart ausgebildet und/oder derart in dem Grundprägeelement/Grundpatrizenelement angeordnet sind, dass das mit einem ersten Grundprägeelement/Grundpatrizenelement erhaltene Prägebild zu dem mit einem weiteren Grundprägeelement/Grundpatrizenelement erhaltenem Prägebild nicht identisch ist. Hierdurch wird in vorteilhafter Weise eine weitere Funktionalität der Prägung bzw. des Prägebildes erreicht, wobei im Fall der Abstapelung aufeinanderzuliegen kommende Folien mit unterschiedlichem Prägebild durch die Unterschiede im Prägebild einen hinreichenden Abstand zu einander haben, um beim Aufnehmen eine Vereinzelung der Folien zu erreichen. Nicht identische Prägebilder im Sinne dieser Erfindung sind dabei beispielsweise Prägebilder die sich in ihrer jeweiligen Relativausrichtung zum Druckbild oder im Prägemuster voneinander unterscheiden. Hinsichtlich der Relativausrichtung kann dabei im Sinne der Erfindung bereits ein Unterschied von ≥0,1 mm, vorzugsweise ≥0,2 mm, insbesondere ≥0,3 mm ausreichend sein.According to the invention, it is provided that the interchangeable embossing elements and / or interchangeable male elements are designed and / or arranged in the basic embossing element / basic male element in such a way that the embossed image obtained with a first basic embossed element / basic male element is not identical to the embossed image obtained with a further basic embossed element / basic male element is. In this way, a further functionality of the embossing or the embossed image is achieved in an advantageous manner, whereby in the case of stacking foils with a different embossed image due to the differences in the embossed image have a sufficient distance from one another to achieve a separation of the foils when picked up. Embossed images that are not identical in the sense of this invention are, for example, embossed images which are in their respective relative orientation to the printed image or in the embossed pattern differ from each other. With regard to the relative alignment, a difference of 0.1 mm, preferably 0.2 mm, in particular 0.3 mm, can be sufficient for the purposes of the invention.

Gemäß einer weiteren Ausgestaltung der Erfindung kann es vorgesehen sein, dass Vorrichtung in einem System angeordnet ist, welches eine Materialzuführung, eine Prägeeinrichtung, sowie eine Stanzeinrichtung umfasst, wobei diese derart zueinander angeordnet sind, dass von der Materialzuführung zugeführtes Folienmaterial zunächst mittels der Prägeeinrichtung geprägt und anschließend mittels der Stanzeinrichtung gestanzt wird. Hierdurch ist in einem integrierten System die Bereitstellung von geprägten Folienelementen, wie z.B. Foliendeckel für Verpackungszwecke möglich.According to a further embodiment of the invention, it can be provided that the device is arranged in a system which comprises a material feed, an embossing device and a punching device, these being arranged with respect to one another in such a way that film material supplied from the material feed is initially embossed and is then punched by means of the punching device. This enables the provision of embossed film elements, such as film lids for packaging purposes, in an integrated system.

Mit dem erfindungsgemäßen Verfahren wird es in vorteilhafter Weise ermöglicht Versiegelungsfolien, wie z.B. Deckel für Verpackungen beispielsweise für Lebensmittel, mit einer multifunktionalen Prägung zu versehen, welche neben der Funktion der Sicherstellung einer hinreichenden Vereinzelbarkeit der Folien bei der Aufnahme von einem Stapel die weitere Funktion eine haptisch wahrnehmbaren Information auf dem Foliendeckel, wie beispielsweise ein Piktogramm oder eine Braille-Markierung bereitzustellen. Hierdurch können beispielsweise hinsichtlich ihrer optischen Wahrnehmung eingeschränkte Personen Informationen über das in der Verpackung befindliche Produkt erhalten. Ebenso ist es möglich, Bildelemente eines auf der Folie aufgebrachten Aufdrucks dreidimensional zu unterstützen.With the method according to the invention it is advantageously made possible to provide sealing foils, such as lids for packaging, for example for food, with a multifunctional embossing which, in addition to ensuring that the foils can be sufficiently separated when they are picked up from a stack, has a further haptic function to provide perceptible information on the foil cover, such as a pictogram or a Braille marking. In this way, for example, people who are restricted in terms of their visual perception can receive information about the product in the packaging. It is also possible to support three-dimensional image elements of an imprint applied to the film.

Gemäß einer Ausgestaltung des erfindungsgemäßen Verfahrens umfasst das mittels der Wechselprägeelemente als haptisch wahrnehmbares Prägebild eine Braille-Markierung und/oder eine Piktogramm.According to one embodiment of the method according to the invention, the embossed image which can be perceived haptically by means of the alternating embossing elements comprises a Braille marking and / or a pictogram.

Fig. 1 zeigt eine Folie (900), welche ein haptisch wahrnehmbares Prägebild (130) aufweist. Die dargestellte Folie (900) kann dabei beispielsweise als Versiegelungsfolie zur Verschließung einer Lebensmittelverpackung, wie beispielsweise ein Joghurtbecher oder dergleichen, dienen. Bei dem haptisch wahrnehmbaren Prägebild (130) kann es sich wie in der gezeigten Ausführungsform gezeigt beispielsweise um Braille-Markierungen handeln, mit deren Hilfe in ihrer optischen Wahrnehmungsfähigkeit eingeschränkten Personen Informationen über den Inhalt der Lebensmittelverpackung vermittelt werden. In der dargestellten Ausführung wird beispielsweise als haptische wahrnehmbare Informationen der Name des Herstellers und die Geschmacksrichtung (Erdbeere) angegeben. Fig. 1 shows a film (900) which has a haptically perceptible embossed image (130). The film (900) shown can be used, for example, as a sealing film for closing a food package, such as a yoghurt pot or the like. As shown in the embodiment shown, the haptically perceptible embossed image (130) can be, for example, Braille markings, with the aid of which information about the contents of the food packaging can be conveyed to persons with restricted optical perception. In the illustrated embodiment, for example, the name of the manufacturer and the flavor (strawberry) are indicated as haptic perceptible information.

Fig. 2 zeigt eine Ausgestaltung einer Vorrichtung (100) zur multifunktionalen Prägung von Folien. Die Vorrichtung weist dabei ein Grundprägeelement (110) mit einem Aufnahmebereich (111), sowie ein innerhalb des Aufnahmebereichs (111) lösbar angeordnete Wechselprägeelemente (120, 121, 122, 123) auf. Die lösbar angeordneten Wechselprägeelemente (120, 121, 122, 123) sind dazu geeignet, beim Prägen der Folie ein eine haptisch wahrnehmbare Information vermittelndes Prägebild zu erzeugen. In der gezeigten Ausführungsform erzeugen beispielsweise die Wechselprägeelement 120, 122 und 123 ein Prägebild der Braille-Markierung für den Buchstaben "e" und das Wechselprägeelement 121 ein Prägebild der Braille-Markierung für den Buchstaben "r". Fig. 2 shows an embodiment of a device (100) for the multifunctional embossing of foils. The device has a base embossing element (110) with a receiving area (111) and an alternating embossing element (120, 121, 122, 123) detachably arranged within the receiving area (111). The detachably arranged alternating embossing elements (120, 121, 122, 123) are suitable for generating an embossed image that provides haptically perceptible information when the film is embossed. In the embodiment shown, for example, the alternating embossing elements 120, 122 and 123 generate an embossed image of the Braille marking for the letter “e” and the alternating embossing element 121 an embossed image of the Braille marking for the letter “r”.

Fig. 3 zeigt eine Prägeplatte (101), welche eine Mehrzahl von Grundprägeelementen (110) aufweist. Jedes der Grundprägeelemente (110) weist dabei wiederum einen Aufnahmebereich zur Aufnahme einer Mehrzahl von Wechselprägeelementen auf. Dabei sind die Wechselprägeelemente derart ausgebildet und/oder derart in dem Grundprägeelement angeordnet, dass das mit einem ersten Grundprägeelement (110) erhaltene Prägebild zu dem mit einem weiteren Grundprägeelement erhaltenem Prägebild nicht identisch ist. Hierdurch wird erreicht, dass bei der Abstapelung von geprägten Folien ein Verhaken der Folien ineinander vermieden werden kann und eine Vereinzelung der Folien bei einer Wiederaufnahme erreicht wird. Fig. 3 shows an embossing plate (101) which has a plurality of basic embossing elements (110). Each of the basic embossing elements (110) in turn has a receiving area for receiving a plurality of alternating embossing elements. The alternating embossing elements are designed and / or arranged in the basic embossing element in such a way that the embossed image obtained with a first basic embossing element (110) is not identical to the embossed image obtained with a further basic embossing element. What is achieved by this is that when the embossed foils are stacked, the foils can be prevented from getting caught in one another and the foils can be separated when they are picked up again.

Fig. 4 zeigt ein System (150), mit welchem aus einem bahnförmigen Folienmaterial, wie beispielsweise einer Aluminiumfolie oder einer Aluminium/Kunststoff-Kompositfolie geprägte Versiegelungsdeckel und ausgestanzt werden können. Das System (150) weist dazu eine Materialzuführung (151) auf, welche ein bahnförmiges Folienmaterial (900) zunächst einer Prägeeinrichtung (152) zuführt. Die Prägeeinrichtung (150) weist dabei eine Prägeplatte mit einer Mehrzahl von Grundprägeelementen auf, welche wiederum jeweils eine Mehrzahl von Wechselprägeelementen aufweisen. Die mittels der Prägeeinrichtung (150) geprägte Folienbahn wird einer Stanzeinrichtung (153) zugeführt, mittels welcher geprägte Folienelemente ausgestanzt werden. Die geprägten und ausgestanzten Folienelemente werden in einem Stapel (154) abgestapelt. Durch das Vorsehen von Grundprägeelementen bzw. Wechselprägeelementen die nicht identische Prägebilder erzeugen wird eine Vereinzelung der in dem Stapel (154) abgestapelten Folienelemente bei eine späteren Wiederaufnahme vereinfacht. Fig. 4 shows a system (150) with which sealing lids can be stamped and stamped out of a sheet material, such as an aluminum foil or an aluminum / plastic composite foil. For this purpose, the system (150) has a material feed (151) which first feeds a web-shaped film material (900) to an embossing device (152). The embossing device (150) has an embossing plate with a plurality of basic embossing elements, which in turn each have a plurality of alternating embossing elements. The film web embossed by means of the embossing device (150) is fed to a punching device (153), by means of which embossed film elements are punched out. The embossed and punched-out film elements are stacked in a stack (154). By providing basic embossing elements or alternating embossing elements which do not generate identical embossed images, separation of the film elements stacked in the stack (154) when they are picked up again is simplified.
