Abstract

The invention relates to the embossing of a foil material with printing marks and pre-sized cover members for food containers (26), said embossing being partly carried out by means of sensors and by means of the regulated tensile force of embossing drums. Said partially embossed cover members (24) comprise a smooth surface area (24b) in the region of the container flange (27) and they are embossed in the rest of the surface area. The surface side (24') facing the container (26) can comprise a heat-sealable coating (25), preferably in the region of the width of the container flange (27). The heat-sealable coating (25') can also be applied in the embossed area (24'), so that the entire area (24') of the cover member is covered with a heat-sealable varnish. Partial embossing of the inventive cover members makes the food containers easy to use by the consumer and their embossed area (24a) also allows for satisfying stacking of said containers at the time of storage.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von teilweise geprägten Deckelelementen für den Verschluß von Behältern, insbesondere Nahrungsmittelbehältern, eine Vorrichtung zur Durchführung dieses Verfahrens sowie nach diesem Verfahren hergestellte, teilweise geprägte Deckelelemente.The invention relates to a method for the production of partially embossed lid elements for the closure of containers, in particular food containers, a device for Implementation of this procedure and according to this procedure manufactured, partially embossed cover elements.

Stand der TechnikState of the art

Deckelelemente für Behälter, beispielsweise für Joghurtbecher werden u.a. durch Ausstanzen von bedruckten Aluminiumfolien hergestellt. Zum luftdichten Verschließen weisen diese Folien an der nicht bedruckten Seite eine Heißsiegellackschicht auf. Nach dem Ausstanzen in die gewünschte Deckelform werden diese in einem Stapel gelagert. Zu deren Weiterverwendung müssen sie beispielsweise mit Saugnäpfen vom Stapel abgehoben werden. Um zu verhindern, daß beim Abheben mehrere Deckel aneinanderhaften, weil sich zwischen ihnen keine Luftschicht befindet, sind die Deckel mit einer Prägung versehen. Diese Prägung erfolgt zumeist an der bedruckten Folie, bevor die Deckelelemente ausgestanzt werden.Der Prägevorgang hat jedoch den Nachteil, daß das Druckbild verzerrt oder sogar zerstört wird.Lid elements for containers, for example for yoghurt cups are among others produced by punching out printed aluminum foils. These films provide instructions for airtight sealing a heat sealing lacquer layer on the unprinted side. To punching them out into the desired shape of the lid is done in one Stacked. To continue using them, for example be lifted off the stack with suction cups. In order to prevent multiple lids from sticking together when lifting off, because there is no air layer between them, they are Emboss the lid. This is usually done on the printed film before the cover elements are punched out However, the embossing process has the disadvantage that the printed image is distorted or even destroyed.

Gemäß der FR-A-2 731 986 werden daher Deckelelemente vorgeschlagen, welche neben einem geprägten auch einen etwa ungeprägten Oberflächenbereich aufweisen. Dieser etwa ungeprägte Oberflächenbereich weist jenen Aufdruck auf, welcher eine für den Verbraucher wesentliche Information, wie Ablaufdatum oder Lebensmittelinhaltsstoffe, darstellt und daher gut lesbar sein muß.According to FR-A-2 731 986, cover elements are therefore proposed which in addition to an embossed surface area also has an unembossed surface area exhibit. This roughly unembossed surface area has the imprint which is essential for the consumer Information such as expiry date or food ingredients, represents and must therefore be legible.

Diese Deckelelemente werden aus bedruckten und anschließend geprägten Folien hergestellt. Für die Ausbildung des etwa ungeprägten Bereiches werden entsprechend geformte Preßwerkzeuge eingesetzt. Diese werden mit hohem Anpreßdruck an die geprägte Folie gepreßt, sodaß der etwa ungeprägte Oberflächenbereich erzeugt wird. These cover elements are made of printed and then embossed Films made. For the training of the roughly unembossed Correspondingly shaped pressing tools are used in the area. These are applied to the embossed film with high contact pressure pressed so that the roughly unembossed surface area is generated.

Dieses Verfahren ist nun deshalb aufwendig, da die Prägung mit zusätzlichen Werkzeugen rückgängig gemacht werden muß. Dennoch verbleibt eine Restprägung, sodaß der Aufdruck verzerrt und somit die Lesbarkeit weiterhin beschwerlich ist.This process is now complex because the embossing with additional tools must be undone. Yet there remains a residual embossing, so that the print is distorted and legibility is still difficult.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art anzugeben, welches einerseits leicht durchführbar ist und wodurch andererseits teilweise geprägte Deckelelemente in Verbraucher-freundlicher Form erzeugt werden.The object of the invention is therefore a method of the beginning specified type, which on the one hand is easy to carry out and, on the other hand, partially embossed cover elements generated in a consumer-friendly form.

Dieses Verfahren ist erfindungsgemäß dadurch gekennzeichnet, daß ein Folienmaterial, an welchem über Druckmarken die Abstände zwischen den vordimensionierten Deckelementen mittels eines Sensors lesbar sind, zwischen zwei Prägewalzen geführt wird, welche neben einem glatten Oberflächenbereich ebenso einen Prägebereich aufweisen und deren Winkelposition vom Sensor ermittelt wird, daß nach Vergleich der durch die Sensoren ermittelten Werte durch den Regler für den Fall der Identität dieser Werte das teilweise geprägte Folienmaterial hergestellt wird, welches über Umlenkrollen einem Stanzwerkzeug zugeführt wird, an dem die teilweise geprägten Deckeleiemente erzeugt werden.This method is characterized in that a film material on which the distances are printed between the pre-dimensioned deck elements using a Sensor readable between two embossing rollers which is next to a smooth surface area also have an embossing area and their angular position the sensor determines that after comparing the values determined by the sensors by the controller in the case of the identity of these values, the partially coined Foil material is produced, which over pulleys a punch is supplied, on which the partially embossed cover elements are generated.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß bei Nicht-Identität der durch die Sensoren ermittelten Werte diese Diskrepanz vom Regler an den Motor weitergeleitet wird, sodaß das Drehmoment der Abwickelvorrichtung vermindert oder erhöht, die Geschwindigkeit der Prägewalzen jedoch konstant gehalten wird, und daß durch diese erzeugte Zugkraft das Folienmaterial um den an den Druckmarken gemessenen Wert gedehnt wird, sodaß Identität der an den Sensor ermittelten Werte vorliegt und der geprägte bzw. ungeprägte Oberflächenbereich dimensionsgerecht innerhalb der Druckmarken erzeugt wird. Another advantage of the method according to the invention is in that the non-identity of those determined by the sensors Values this discrepancy passed on from the controller to the motor is so that the torque of the unwinder reduces or increases the speed of the embossing rollers however, is kept constant, and that generated by this Traction the film material around the at the print marks measured value is stretched so that the identity of the Values determined by the sensor and the embossed or non-embossed surface area within the dimension Print marks is generated.

Bevorzugt besteht das in das erfindungsgemäße Verfahren eingesetzte Folienmaterial aus Kunststoff oder Aluminium mit einer Zugfestigkeit von 50 bis 200 N/mm2 oder aus einem Verbund mit folgenden Materialkombinationen: Aluminium/Aluminium, Aluminium/Kunststoff, Aluminium/Papier, Aluminium/Papier/Kunststoff, Kunststoff/Kunststoff, Kunststoff/Papier, Aluminium/Papier/Aluminium, Aluminium/Kunststoff/Aluminium.The film material used in the method according to the invention preferably consists of plastic or aluminum with a tensile strength of 50 to 200 N / mm 2 or of a composite with the following material combinations: aluminum / aluminum, aluminum / plastic, aluminum / paper, aluminum / paper / plastic, Plastic / plastic, plastic / paper, aluminum / paper / aluminum, aluminum / plastic / aluminum.

Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung eines Verfahrens zur Herstellung von teilweise geprägten Deckelelementen für den Verschluß von Behältern, wobei diese aus einer durch den Motor angetriebenen Abwickelvorrichtung, dem Sensor für die Ermittlung der Position der Druckmarken des Folienmaterials, der Prägestation, welche aus den teilweise im Oberflächenbereich glatten Prägewalzen gebildet wird, deren Winkelposition vom Sensor ermittelt wird, wobei die Sensoren mit dem Regler geschaltet sind, welcher aufgrund des ermittelten Wertes das Drehmoment des Motors steuert, sowie aus mehreren Umlenkrollen, einem Verschubwalzenpaar und einem Stanzwerkzeug besteht.The invention further relates to a device for performing a process for the production of partially embossed cover elements for the closure of containers, these from a by the motor driven unwinder, the sensor for determining the position of the print marks of the Foil material, the embossing station, which partially from the smooth embossing rollers in the surface area is formed, the angular position of the sensor is determined, the sensors with the controller are switched, which on the basis of the determined value Torque of the motor controls, as well as from several pulleys, a pair of displacement rollers and one Punching tool exists.

Die Erfindung wird nun anhand von Ausführungsbeispielen näher erläutert:The invention will now be described with reference to exemplary embodiments explains:

In einer Ausführungsform weist das Folienmaterial 1 die vordimensionierten Deckelelemente 2 auf. Diese können derart bedruckt sein, daß für den geprägten Bereich der Aufdruck 3 und für den ungeprägten Bereich der Aufdruck 4, beispielsweise in Form einer für den Verbraucher wichtigen Beschriftung, vorgesehen sind. Zur Markierung des Abstandes zwischen den einzelnen Deckelelementabschnitten 2 sind auf dem Folienmaterial 1 die Druckmarken 5 vorgesehen. In one embodiment, the film material 1 has the pre-dimensioned Cover elements 2. These can be printed in this way be that for the embossed area the print 3 and for the non-embossed area of the imprint 4, for example in the form of a important labeling for the consumer are provided. to Marking the distance between the individual cover element sections 2 are the printing marks 5 on the film material 1 intended.

Das Folienmaterial 1 kann beispielsweise Kunststoff oder Aluminium mit einer Zugfestigkeit von 50 bis 130 N/mm2 sein. Es ist jedoch auch möglich, Verbundmaterialien hoher Zugfestigkeit einzusetzen, wobei aus folgenden Materialkombinationen ausgewählt werden kann: Aluminium/Aluminium, Aluminium/Kunststoff, Aluminium/Papier, Aluminium/Papier/Kunststoff, Kunststoff/Kunststoff, Kunststoff/Papier, Aluminium/Papier/Aluminium, Aluminium/Kunststoff/Aluminium.The film material 1 can be, for example, plastic or aluminum with a tensile strength of 50 to 130 N / mm 2 . However, it is also possible to use composite materials with high tensile strength, whereby the following material combinations can be selected: aluminum / aluminum, aluminum / plastic, aluminum / paper, aluminum / paper / plastic, plastic / plastic, plastic / paper, aluminum / paper / aluminum , Aluminum / plastic / aluminum.

Das Folienmaterial 1 wird nun entsprechend der Geschwindigkeit des Motors 7 von der Vorrichtung 6 abgewickelt und passiert den Sensor 8. Dieser ermittelt in Längsrichtung den Abstand Y der Druckmarken 5 (siehe Fig. 2) und gibt diesen Wert an den Regler 9 weiter. Anschließend wird die Folie 1 in die Prägestation 10, geführt, welche aus den Prägewalzen 11 und 12 besteht. Diese weisen an ihrer Oberflächen die Prägebereiche 11a, 12a sowie die glatten Bereiche 11b, 12b, durch welchen der ungeprägte Deckelbereich ausgebildet wird, auf. Die Winkelposition der Prägewalzen 11,12 wird mittels des Sensors 13 festgestellt und ebenso an den Regler 9 weitergeleitet. Der Regler 9 vergleicht die ermittelten Werte. Ergeben diese eine Übereinstimmung, so ist es gewährleistet, daß zwischen zwei Druckmarken 5 entsprechend den Prägewalzenoberflächen 11a und 11b bzw. 12a und 12b ein Deckelelement 14 mit geprägtem bzw. passergenau ungeprägtem Oberflächenbereichen 14a bzw. 14b entsteht.The film material 1 is now in accordance with the speed of the motor 7 unwound from the device 6 and passes the Sensor 8. This determines the distance Y in the longitudinal direction Print marks 5 (see Fig. 2) and gives this value to the controller 9 further. The film 1 is then placed in the embossing station 10, performed, which consists of the embossing rollers 11 and 12. This have on their surfaces the embossed areas 11a, 12a and smooth areas 11b, 12b through which the unembossed Cover area is formed on. The angular position of the Embossing rollers 11, 12 are determined by means of the sensor 13 and also forwarded to the controller 9. The controller 9 compares the determined values. If they match, so it is ensured that between two print marks 5 corresponding to the embossing roller surfaces 11a and 11b or 12a and 12b a cover element 14 with an embossed or register-accurate Unembossed surface areas 14a and 14b are formed.

Sind diese Werte jedoch voneinander abweichend, so wird die Differenz ermittelt und durch den Regler 9 an den Motor 7 weitergegeben. Wird das Drehmoment des Motors 7 entsprechend der ermittelten Differenz reduziert, die Drehgeschwindigkeit der Prägewalzen 11 und 12 jedoch beibehalten, so wird eine Zugkraft auf die Folienbahn 1 ausgeübt und das Material auf den gewünschten Druckmarkenabstand X gedehnt (siehe Fig.2).However, if these values differ, the difference becomes determined and passed on to the motor 7 by the controller 9. The torque of the motor 7 is determined according to the Difference reduced, the speed of rotation of the embossing rollers 11 and 12, however, will maintain a tensile force the film web 1 exercised and the material to the desired Print mark spacing X extended (see Fig. 2).

By the Stamping tool 23, the finished cover elements 14 in the desired shape punched and stacked.

Die endgefertigten Deckelelemente 14 weisen einen geprägten Bereich 14a und den ungeprägten Bereich 14b auf. Eventuelle Beschriftungen, die für den Konsumenten wesentlich sind, sind im ungeprägten Bereich 14b angebracht und weisen eine zufriedenstellende Lesbarkeit auf.The finished cover elements 14 have an embossed area 14a and the unembossed area 14b. Any labels, which are essential for the consumer are in the embossed area 14b attached and have a satisfactory Legibility.

In einer weiteren Ausführungsform werden die teilweise geprägten Deckelelemente 24 erzeugt. Daher weist das Folienmaterial 1 ebenso die vordimensionierten Deckelelemente 2 auf nur mit dem Unterschied, daß eine heißsiegelnde Beschichtung 25, 25' beispielsweise in Form eines Heißsiegellackes vorgesehen ist. Der Aufdruck 4 kann entfallen.In a further embodiment, the partially embossed Cover elements 24 generated. Therefore, the film material 1 likewise the pre-dimensioned cover elements 2 on only with the Difference that a heat-sealing coating 25, 25 ' for example in the form of a heat seal lacquer. The imprint 4 can be omitted.

Ferner werden anstelle der Prägewalzen 11 und 12 die Prägewalzen 11' und 12' in der Prägestation 10 eingesetzt. Diese weisen die glatten Oberflächenbereiche 11'b, 12'b auf, durch welche der glatte Oberflächenbereich 24b erzeugt wird. Durch die Prägebereiche 11'a, 12'a wird der geprägte Bereich 24a erzeugt.Furthermore, instead of the embossing rollers 11 and 12, the embossing rollers 11 'and 12' used in the embossing station 10. These show the smooth surface areas 11'b, 12'b through which the smooth surface area 24b is generated. Through the Embossed areas 11'a, 12'a, the embossed area 24a is produced.

Der glatte Oberflächenbereich 24b kann dabei in seiner Breite dem Flansch 27 des Nahrungsmittelbehälters 26 entsprechen und weist vorzugsweise die heißsiegelnde Beschichtung 25 auf. Es ist jedoch ebenso möglich, die heißsiegelnde Beschichtung 25' zusätzlich im geprägten Bereich aufzutragen, sodaß das Deckelelement insgesamt an seiner Oberfläche 24' mit Heißsiegellack versehen ist.The smooth surface area 24b can have a width correspond to the flange 27 of the food container 26 and preferably has the heat-sealing coating 25. It is however, it is also possible to use the heat-sealing coating 25 ' additionally apply in the embossed area, so that the cover element in total on its surface 24 'with heat sealing lacquer is provided.

Die weitere Verfahrensführung entspricht der vorgenannten Ausführungsform.The further procedure corresponds to the above Embodiment.

Die Deckelelemente 24 sind nun - bedingt durch den stark ausgebildeten geprägten Bereich 24a - leicht entstapelbar. Sie sind jedoch insoferne Verbraucher-freundlich, da sie sich leicht vom Flansch 27 des Nahrungsmittelbehälters 26 abziehen lassen. Dies wird durch die glatte Oberfläche im Bereich 24b, in welchem vorzugsweise die heißsiegelnde Beschichtung 25 vorgesehen ist, bewirkt. The cover elements 24 are now - due to the strong formed embossed area 24a - easy to unstack. she however, are consumer-friendly in that they are easy pull off the flange 27 of the food container 26. This is due to the smooth surface in the area 24b in which preferably the heat-sealing coating 25 is provided, causes.
