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.
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.
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.

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
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
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
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
Anschließend wird die teilweise geprägte Folie 15 über mehrere
Umlenkwalzen 16, 17, 18, 19 und 20 dem Vorschubwalzenpaar 21
zugeführt, welches durch den Leser 22 gesteuert wird. Durch das
Stanzwerkzeug 23 werden die endgefertigten Deckelelemente 14 in
die gewünschte Form gestanzt und gestapelt. Then the partially embossed
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
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
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
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
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
Die durch das erfindungsgemäße Verfahren hergestellten, teilweise geprägten Deckelelemente sind besonders Verbraucherfreundlich, da sie sich leicht vom Nahrungsmittelbehälter abziehen lassen oder aber für den Verbraucher gut lesbare Beschriftungen aufgrund ihrer Anordnung im ungeprägten Bereich aufweisen. Davon unabhängig sind sie auch gut entstapelbar bedingt durch ihren geprägten Oberflächenbereich, welcher jeweils unmittelbar an den ungeprägten Bereich anschließt.The parts produced by the method according to the invention embossed cover elements are particularly consumer-friendly, because they peel easily from the food container leave or easily legible labels for the consumer due to their arrangement in the unembossed area. Regardless of this, they are also conditionally easy to unstack due to its embossed surface area, which is always direct connects to the unembossed area.
