Description

Die Erfindung betrifft eine Anordnung nach dem Oberbegriff des Anspruchs 1 bzw. 2, zum positionsgenauen Bedrucken einer markierungsfreien ersten Folie, welche in Abschnitten einer Abschnittslänge Elemente aufweist und mit einer zweiten Folie zusammenfügbar ist, wobei die zweite Folie, Markierungen aufweist, welche einen vorbestimmten Abstand zueinander aufweisen, welcher bis auf eine gegebenenfalls vorhandene Differenz der Abschnittslänge entspricht, wobei die Elemente in Bezug auf die Markierungen der zweiten Folie positionsgenau auf die erste Folie aufbringbar sind, mit einer ersten Vorrichtung, mittels welcher die beiden Folien miteinander verbindbar sind, einer Transportvorrichtung, mittels welcher die beiden Folien um den vorbestimmten Abstand abschnittsweise weiter transportierbar sind, und mit einer zweiten Vorrichtung mit einem Aktivierungseingang, mittels welcher auf die erste Folie immer dann ein Element positionsgenau aufgebracht wird, wenn ein Signal am Aktivierungseingang angelegt wird.The invention relates to an arrangement according to the preamble of claim 1 or 2, for positionally accurate printing of a mark-free first film, which has elements in sections of a section length and can be joined with a second film, wherein the second film, having markings which a predetermined distance to each other, which corresponds to a possibly existing difference in the section length, wherein the elements with respect to the markings of the second film are positionally accurately applied to the first film, with a first device by means of which the two films are connected to each other, a transport device, by means of which the two films are further transportable sections by section by the predetermined distance, and with a second device having an activation input, by means of which an element is applied to the first film in an exact position whenever a signal is applied to the activating ring ng is created.

Mittels einer derartigen Anordnung werden beispielsweise sogenannte Blisterverpackungen hergestellt, mittels welcher beispielsweise Tabletten vertrieben werden. Eine Blisterverpackung besteht im Regelfall aus einer aus Kunststoff oder Papier bestehenden Tiefziehfolie, in welcher als sogenannte Höfe bezeichnete Vertiefungen ausgebildet sind, in der sich die Tabletten befinden, und welche mittels einer Deckfolie versiegelt sind. Auf der Deckfolie befindet sich regelmäßig ein Druckbild, welches üblicherweise Angaben über die Tabletten enthält, wie beispielsweise Daten darüber, wann welche Tabletten einzunehmen sind. Es ist daher entscheidend, daß diese Angaben entsprechend der Position der Tabletten und damit der Höfe positionsgenau auf der Deckfolie angebracht sind.By means of such an arrangement, for example so-called blister packs are produced, by means of which, for example, tablets are sold. As a rule, a blister pack consists of a thermoforming foil consisting of plastic or paper in which cavities designated as so-called cavities are formed, in which the tablets are located, and which are sealed by means of a cover foil. On the cover sheet is regularly a printed image, which usually contains information about the tablets, such as data on when to take which tablets. It is therefore crucial that these statements are placed in exact position on the cover sheet according to the position of the tablets and thus the courtyards.

Wenngleich auch mit den heute bekannten Drucktechniken eine sehr große Maßgenauigkeit erreicht werden kann, so stellt die positionsgenaue Zuordnung des Druckbildes der Deckfolie zu der Tiefziehfolie ein großes Problem dar, da sich vorhandene Abweichungen addieren können. Im Laufe der Zeit würde daher die Position eines Druckbilds von der erforderlichen Position um ein nicht mehr tolerierbares Maß abweichen. Es wurden daher Druckvorrichtungen entwickelt, mittels welcher die Positionsgenauigkeit des Druckbildes auf der Deckfolie wesentlich erhöht wurde. So ist beispielsweise aus der DE 195 25 713 C1 eine Vorrichtung zum positionsgenauen Bedrucken einer markierungsfreien Endlosfolie bekannt, mittels welcher Druckbilder einer ersten vorbestimmten Länge auf eine Metallfolie aufgebracht werden, wobei die Folie nach dem Bedrucken in Abschnitte einer zweiten vorbestimmten Länge mittels einer Trennvorrichtung aufgeteilt wird und die Druckbilder in bezug auf die Trennstellen zwischen den Abschnitten positionsgenau auf die Folie aufgebracht werden müssen.Although a very large dimensional accuracy can be achieved with the printing techniques known today, so the positionally accurate assignment of the printed image of the cover sheet to the thermoforming film is a major problem, since existing deviations can add. Over time, therefore, the position of a printed image would deviate from the required position by an intolerable measure. Therefore, printing devices were developed by means of which the positional accuracy of the printed image on the cover film was substantially increased. For example, from the DE 195 25 713 C1 a device for the positionally accurate printing of a mark-free endless film is known, are applied by means of which printed images of a first predetermined length on a metal foil, the film is divided after printing in sections of a second predetermined length by means of a separating device and the printed images with respect to the separation points between the Sections must be applied exactly positioned on the film.

Bei der bekannten Vorrichtung ist ein Drucker vorhanden, welcher einen Eingang zum Auslösen eines positionsgenauen Druckvorgangs hat. Des weiteren ist ein Sensor vorhanden, welcher immer dann an seinem Ausgang ein Signal abgibt, wenn die Länge der Folie zwischen der Trennvorrichtung und der dem Anfang eines zu bedruckenden Abschnitts entsprechenden Stelle einem vorbestimmten Vielfachen der zweiten vorbestimmten Länge entspricht.In the known device, a printer is provided which has an input for triggering a positionally accurate printing operation. Furthermore, a sensor is present, which always emits a signal at its output when the length of the film between the separator and the Beginning of a section to be printed corresponding to a predetermined multiple of the second predetermined length.

Da der Ausgang des Sensors mit dem Ausgang des Druckers verbunden ist, wird erreicht, daß der Anfang eines zu bedruckenden Abschnitts der Folie stets aufs Neue festgelegt wird. Durch die ständig neue Festlegung des Anfangs eines bedruckenden Abschnitts kann sich ein eventuell vorhandener Fehler nicht addieren. Somit sind selbst relativ große Abweichungen in der Regel unschädlich, da die bei einem Abschnitt vorhandene Abweichung keinen Einfluß auf den Anfang des nächsten zu bedruckenden Abschnitts hat.Since the output of the sensor is connected to the output of the printer, it is achieved that the beginning of a portion of the film to be printed is always set anew. Due to the constant redefinition of the beginning of a printing section, any existing error can not add up. Thus, even relatively large deviations are usually harmless, since the deviation present at one section has no influence on the beginning of the next section to be printed.

Des weiteren ist aus der DE 198 50 275 eine weitere Vorrichtung zum positionsgenauen Bedrucken einer markierungsfreien Endlosfolie bekannt, welche im Ergebnis nach demselben Prinzip arbeitet, wie die zuvor genannte Druckvorrichtung. Der wesentlichste Unterschied zu der zuvor genannten Druckvorrichtung besteht darin, daß bei der zuvor genannten Druckvorrichtung der Transport der Endlosfolie diskontinuierlich erfolgt, wohingegen der Transport bei der weiteren Druckvorrichtung kontinuierlich erfolgt. Die Aktivierung des Druckers erfolgt jedoch ebenfalls immer dann, wenn die Länge der Endlosfolie zwischen der durch die jeweils letzte vorgenommene Aufteilung erzeugten Abschnittsgrenze und der Druckeinrichtung ein vorbestimmtes Vielfaches der zweiten vorbestimmten Länge beträgt.Furthermore, from the DE 198 50 275 another device for positionally accurate printing a mark-free endless film is known, which operates as a result of the same principle as the aforementioned printing device. The most significant difference to the aforementioned printing device is that in the aforementioned printing device, the transport of the endless film takes place discontinuously, whereas the transport takes place continuously in the further printing device. However, the activation of the printer also occurs whenever the length of the continuous film between the section boundary produced by the most recent division and the printing device is a predetermined multiple of the second predetermined length.

Wenngleich mittels der bekannten Vorrichtungen auch hervorragende Ergebnisse erzielt werden, so hat sich dennoch herausgestellt, daß aufgrund äußerer Einflüsse eine Verschiebung des Druckbildes in bezug auf die Höfe erfolgen kann. Insbesondere nach einem Stillstand der Anordnungen sind teilweise nicht mehr tolerierbare Abweichungen vorhanden.Although excellent results are achieved by means of the known devices, it has nevertheless been found that, due to external influences, a displacement of the printed image with respect to the courtyards can take place. In particular, after a stoppage of the arrangements partially unacceptable deviations are present.

Es ist Aufgabe der Erfindung, eine eingangs genannte Anordnung derart auszubilden, daß Positionsverschiebungen der auf der ersten Folie aufgebrachten Elementen zu den auf der zweiten Folie aufgebrachten Markierungen sehr gering sind.It is an object of the invention to form an initially mentioned arrangement such that positional displacements of the applied on the first film Elements to the applied on the second film markers are very low.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des kennzeichnenden Teils des Anspruchs 1 und des Kennzeichnenden Teils des Anspruchs 2. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of this problem arises from the features of the characterizing part of claim 1 and the characterizing part of claim 2. Advantageous developments of the invention will become apparent from the dependent claims.

Gemäß der Erfindung ist eine Anordnung zum positionsgenauen Bedrucken einer markierungsfreien ersten Folie, welche in Abschnitten einer Apschnittslänge Elemente aufweist und mit einer zweiten Folie zusammenfügbar ist, wobei die zweite Folie Markierungen aufweist, welche einen vorbestimmten Abstand zueinander aufweisen, welcher bis auf eine gegebenenfalls vorhandene Differenz der Abschnittslänge entspricht, wobei die Elemente in Bezug auf die Markierungen der zweiten Folie positionsgenau auf die erste Folie aufbringbar sind, mit einer ersten Vorrichtung, mittels welcher die beiden Folien miteinander verbindbar sind, einer Transportvorrichtung, mittels welcher die beiden Folien um den vorbestimmten Abstand abschnittsweise weiter transportiertbar sind, und mit einer zweiten Vorrichtung mit einem Aktivierungseingang, mittels welcher auf die erste Folie immer dann ein Element positionsgenau aufbringbar ist, wenn ein Signal am Aktivierungseingang angelegt wird, dadurch gekennzeichnet, daß ein Sensor vorhanden ist, mittels welchem die Markierungen erfaßbar sind, und welcher bei jeder erfaßten Markierung ein Signal an den Aktivierungseingang der zweiten Vorrichtung anlegt.According to the invention, an arrangement for positionally accurate printing of a mark-free first film which has elements in sections of Apschnittslänge and is joined with a second film, wherein the second film has markings which have a predetermined distance from each other, which except for any difference the section length corresponds, wherein the elements with respect to the markings of the second film are positionally accurately applied to the first film, with a first device by means of which the two films are connected to each other, a transport device by means of which the two films by the predetermined distance sections can be transported, and with a second device with an activation input, by means of which on the first film, an element is always applied positionally accurate when a signal is applied to the activation input, characterized, d a sensor is present, by means of which the markings can be detected, and which applies a signal to the activation input of the second device at each detected mark.

Dadurch, daß ein Sensor vorhanden ist, mittels welchem die Markierungen erfaßbar sind, und welcher bei jeder erfaßten Markierung ein Signal an den Aktivierungseingang der zweiten Vorrichtung anlegt, wird auf einfache Weise eine Synchronisation zwischen den auf die erste Folie aufgebrachten Elementen und den Markierungen erreicht. Das heißt, weist der vorbestimmte Abstand zweier aufeinanderfolgenden Markierungen gegenüber der Abschnittslänge der Abschnitte der ersten Folie eine Differenz auf, wird das Element entsprechend der Differenz versetzt auf die erste Folie aufgebracht. Die Elemente befinden sich somit entsprechend der jeweils aufgetretenen Differenz in Bezug auf die Grenzen zwischen zwei aufeinanderfolgenden Abschnitten verschoben auf der ersten Folie. Es ist somit nicht mehr erforderlich, eine weitere Korrektur vorzunehmen.Characterized in that a sensor is present, by means of which the markings are detectable, and which applies a signal to the activation input of the second device at each detected mark, a synchronization between the elements applied to the first sheet and the markings is achieved in a simple manner. That is, if the predetermined distance between two successive markers and the portion length of the portions of the first foil has a difference, the element is applied offset to the first foil according to the difference. The elements are located Thus, according to the difference that has occurred with respect to the boundaries between two successive sections shifted on the first slide. It is therefore no longer necessary to make a further correction.

Besonders vorteilhaft ist es, die erfindungsgemäße Anordnung zum positionsgenauen Zusammenfügen von einer ein Druckbild aufweisenden Aluminiumfolie und einer sogenannten Höfe aufweisenden Kunststoffolie zu verwenden.It is particularly advantageous to use the arrangement according to the invention for the positionally accurate joining of a plastic foil having a printed image and an aluminum foil having a so-called court.

Als besonders vorteilhaft hat sich eine Ausführungsform der Erfindung herausgestellt, welche eine Offset-Einrichtung aufweist, mittels welcher die Länge der ersten Folie zwischen der ersten Vorrichtung und der zweiten Vorrichtung einstellbar ist. Durch die Offset-Einrichtung läßt sich die Position des Elementes zur Grenze zwischen zwei aufeinanderfolgenden Abschnitten auf einfache Weise verändern. Dies könnte beispielsweise dann erforderlich sein, wenn sich die Länge der ersten Folie zwischen der ersten Vorrichtung und der zweiten Vorrichtung oder die Länge der zweiten Folie zwischen der ersten Vorrichtung und dem Sensor beispielsweise durch Materialdehnung oder -schrumpfung verändert hat. Des weiteren läßt sich die Anordnung durch die Offset-Einrichtung auf einfache Weise bei der Inbetriebnahme einstellen. Die Offset-Einrichtung kann eine mechanische Konstruktion sein oder als elektronische Schaltung ausgebildet sein, mittels welcher ein gegebenenfalls zu korrigierender Offset rechnerisch korrigiert wird.An embodiment of the invention has been found to be particularly advantageous, which has an offset device, by means of which the length of the first film between the first device and the second device is adjustable. By the offset means, the position of the element to the boundary between two successive sections can be changed easily. This could be necessary, for example, if the length of the first film between the first device and the second device or the length of the second film between the first device and the sensor has changed, for example due to material expansion or shrinkage. Furthermore, the arrangement can be adjusted by the offset device in a simple manner during commissioning. The offset device may be a mechanical design or be designed as an electronic circuit, by means of which an optionally correctable offset is computationally corrected.

Des weiteren hat die erfindungsgemäße Anordnung den Vorteil, daß bei einem Formatwechsel, das heißt bei einer Änderung des vorbestimmten Abstands der Markierungen der zweiten Folie beziehungsweise dementsprechend einer Änderung der Abschnittslänge der Abschnitte der ersten Folie keine besonderen Maßnahmen ergriffen werden müssen. Lediglich muß der Sensor entsprechend des neuen Abstands der Markierungen positioniert werden.Furthermore, the arrangement according to the invention has the advantage that in a format change, that is, when changing the predetermined distance of the markings of the second film or, accordingly, a change in the section length of the sections of the first film no special measures must be taken. Only the sensor must be positioned according to the new distance of the markers.

Durch den einfachen Aufbau der erfindungsgemäßen Anordnung wird des weiteren eine höhere Zuverlässigkeit erreicht.Due to the simple structure of the arrangement according to the invention, furthermore, a higher reliability is achieved.

Bei der Ausführungsform der Erfindung nach Anspruch 2 ist vorgesehen, daß in Transportrichtung der ersten Folie vor und hinter der Offset-Vorrichtung jeweils ein Element zum Transport der ersten Folie angeordnet ist. Durch die Transportelemente wird in vorteilhafter Weise erreicht, daß die Länge der sich zwischen den beiden Transportelementen befindlichen Folien variiert werden kann. Dies ist insbesondere bei Wartungsarbeiten oder bei der Inbetriebnahme der Anordnung von Vorteil.In the embodiment of the invention according to claim 2, it is provided that in the transport direction of the first film in front of and behind the offset device in each case an element for transporting the first film is arranged. By the transport elements is achieved in an advantageous manner that the length of the films located between the two transport elements can be varied. This is particularly advantageous during maintenance work or during commissioning of the arrangement.

Bei der letztgenannten Ausführungsform weisen die Transportelemente jeweils einen Geber auf, mittels welcher die Länge des jeweils transportierten Folie erfaßbar ist. Hierdurch läßt sich feststellen, ob die Länge der weitertransportierten ersten Folie in Transportrichtung vor der Offset-Vorrichtung genauso groß ist, wie die Länge der durch das Transportelement weitertransportierten ersten Folie in Transportrichtung der ersten Folie hinter der Offset-Vorrichtung. Stimmen die beiden Längen nicht überein, ergibt sich eine unerwünschte Verschiebung der Position des Elements auf der ersten Folie.In the latter embodiment, the transport elements each have a donor, by means of which the length of each transported film can be detected. This makes it possible to determine whether the length of the further transported first film in the transport direction in front of the offset device is the same size as the length of the further transported by the transport element first film in the transport direction of the first film behind the offset device. If the two lengths do not match, there will be an undesirable shift in the position of the element on the first film.

Bei dieser Ausführungsform der Erfindung ist eine Steuerung vorgesehen, mittels welcher das Aktivierungssignal der zweiten Vorrichtung in Abhängigkeit der Gebersignale verzögerbar ist. Ergibt sich beispielsweise, daß die Länge der von dem in Transportrichtung der ersten Folie vor der Offset-Vorrichtung angeordneten Transportelement transportierten Folie geringer ist, als die Länge der von dem in Transportrichtung hinter der Offset-Vorrichtung angeordneten Transportelement transportierten Folie, wird das vom Sensor ausgegebene Signal um eine entsprechende Zeit verzögert, so daß das an den Aktivierungseingang der zweiten Vorrichtung angelegte Signal derart verzögert ist, daß das Element positionsgenau auf die erste Folie aufgebracht wird.In this embodiment of the invention, a control is provided, by means of which the activation signal of the second device in response to the encoder signals can be delayed. If, for example, it results that the length of the film transported by the transport element arranged in front of the offset device in the direction of transport of the first film is shorter than the length of the film transported by the transport element arranged downstream of the offset device, the film emitted by the sensor becomes Signal delayed by a corresponding time, so that the signal applied to the activation input of the second device signal is delayed such that the element is applied positionally accurate on the first film.

Mittels der erfindungsgemäßen Anordnung ist es möglich, insbesondere nach einem Stillstand einer Blister-Verpackungsmaschine, nach dem sich die Position des Druckbildes bezogen auf die Vertiefungen regelmäßig verschoben hat, in sehr kurzer Zeit wieder die Positionsgenauigkeit des Druckbildes herzustellen.By means of the arrangement according to the invention, it is possible, in particular after a stoppage of a blister packaging machine, after which the position of the printed image has shifted relative to the wells regularly to restore the positional accuracy of the printed image in a very short time.

Weitere Einzelheiten, Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines besonderen Ausführungsbeispiels unter Bezugnahme auf die Zeichnung.Further details, features and advantages of the present invention will become apparent from the following description of a particular embodiment with reference to the drawings.

Es zeigt die einzige Figur eine schematische Darstellung einer erfindungsgemäßen Anordnung.The single figure shows a schematic representation of an arrangement according to the invention.

Wie der Figur entnommen werden kann, wird in erfindungsgemäßer Weise eine als Aluminiumfolie ausgebildete erste Folie 1 in einer als Siegelstation ausgebildeten ersten Vorrichtung 3 mit einer als Kunststoffolie ausgebildeten zweiten Folie 2 verbunden. Die Kunststoffolie 2 weist als sogenannte Höfe 2b bezeichnete Vertiefungen 2b auf. Mehrere Vertiefungen 2b sind jeweils zu einer Gruppe zusammengefaßt, von der die in Transportrichtung gesehen vordere Kante des ersten Hofes 2b eine Markierung 2a darstellt. Die Markierungen 2a befinden sich in einem vorbestimmten Abstand A2 zueinander.As can be seen from the figure, a first film 1 designed as an aluminum foil is connected in a manner according to the invention in a first device 3 designed as a sealing station to a second film 2 designed as a plastic film. The plastic film 2 has recesses 2b referred to as so-called courtyards 2b. Several recesses 2b are each combined to form a group, of which the front edge of the first yard 2b, seen in the direction of transport, represents a marking 2a. The markers 2a are at a predetermined distance A2 to each other.

Die Höfe 2b werden mit einem Prägewerkzeug 15 in die Kunststoffolie 2 geprägt, welche von einer Rolle 14 abgewickelt wird.The yards 2b are embossed with a stamping tool 15 in the plastic film 2, which is unwound from a roll 14.

In einer in der Figur nicht dargestellten Füllstation werden in die Höfe 2b Tabletten eingelegt. Nach dem Einlegen der Tabletten werden die Höfe 2b in der Siegelstation 3 mit der Aluminiumfolie 1 versiegelt. Hierdurch entsteht eine sogenannte Blisterverpackung. Da derartige Blisterverpackungen regelmäßig Informationen enthalten müssen, weist die Aluminiumfolie 1 ein Druckbild B auf.In a filling station, not shown in the figure 2b tablets are inserted into the courtyards. After inserting the tablets, the farms 2b are sealed in the sealing station 3 with the aluminum foil 1. This creates a so-called blister packaging. Since such blister packs must regularly contain information, the aluminum foil 1 has a printed image B.

Es ist zwingend erforderlich, daß das Druckbild B relativ zu den Höfen positionsgenau angeordnet ist.It is imperative that the printed image B is positioned accurately relative to the courts.

Zum Bedrucken der Aluminiumfolie 1, welche von einer Rolle 13 abgewickelt wird, wird diese durch einen Drucker 4 geführt. Zur Auslösung eines positionsgenauen Druckvorgangs besitzt der Drucker 4 einen Eingang 4a.For printing on the aluminum foil 1, which is unwound from a roll 13, this is passed through a printer 4. To trigger a position-accurate printing operation, the printer 4 has an input 4a.

In Transportrichtung der Aluminiumfolie 1 wird diese hinter dem Drucker 4 um eine ein erstes Transportelement bildende erste Umlenkrolle 11 umgelenkt und weitertransportiert. Hinter der ersten Umlenkrolle 11 umschlingt die Aluminiumfolie 1 S-förmig eine Tänzerwalze 10 sowie eine Offsetwalze 6. Die Tänzerwalze 10 sowie die Offsetwalze 6 befinden sich jeweils im Grund von Schlaufen, welche durch den Verlauf der Aluminiumfolie 1 gebildet werden. Hinter der Offsetwalze 6 wird die Aluminiumfolie 1 um eine ein zweites Transportelement bildende zweite Umlenkwalze 12 umgelenkt und weitertransportiert. In Transportrichtung der Aluminiumfolie 1 befindet sich hinter der zweiten Umlenkwalze 12 eine Transportvorrichtung 5, mittels welcher die Aluminiumfolie 1 diskontinuierlich um den vorbestimmten Abstand A2 der Markierungen 2a der Kunststoffolie 2 weiterbewegt wird. Im störungsfreien Fall entspricht die Länge A1 eines Abschnitts, innerhalb welchem das Druckbild B positionsgenau angeordnet sein muß, dem vorbestimmten Abstand A2 der Markierungen 2a der Kunststoffolie 2. Zwischen den Abschnitten befindet sich eine theoretische Trennstelle T.In the transport direction of the aluminum foil 1, this is deflected behind the printer 4 about a first guide roller 11 forming a first transport element and transported further. Behind the first guide roller 11, the aluminum foil 1 wraps around a dancer roller 10 and an offset roller 6 in an S shape. The dancer roller 10 and the offset roller 6 are each located in the bottom of loops which are formed by the course of the aluminum foil 1. Behind the offset roller 6, the aluminum foil 1 is deflected about a second deflection roller 12 forming a second transport element and transported further. In the transport direction of the aluminum foil 1 is behind the second guide roller 12, a transport device 5, by means of which the aluminum foil 1 discontinuously by the predetermined distance A2 of the markers 2a of the plastic film 2 is further moved. In the event of a fault, the length A1 of a section within which the printed image B must be positioned with exact position corresponds to the predetermined distance A2 of the markings 2a of the plastic film 2. Between the sections there is a theoretical separation point T.

Die erste Umlenkrolle 11 ist mit einem Geber 11 a verbunden, mittels welchem die Länge der von der ersten Umlenkrolle 11 transportierte Aluminiumfolie 1 erfaßbar ist. Die zweite Umlenkwalze 12 ist mit einem zweiten Geber 12a verbunden, mittels dem die Länge der von der zweiten Umlenkrolle 12 transportierten Aluminiumfolie 1 erfaßbar ist. Die Umlenkrollen 11, 12 können Antriebe zum Transport der Aluminiumfolie 1 aufweisen.The first guide roller 11 is connected to a transmitter 11 a, by means of which the length of the transported from the first guide roller 11 aluminum foil 1 can be detected. The second deflecting roller 12 is connected to a second encoder 12a, by means of which the length of the aluminum foil 1 transported by the second deflecting roller 12 can be detected. The deflection rollers 11, 12 may have drives for transporting the aluminum foil 1.

Vor der Transportvorrichtung 5 ist die Siegelvorrichtung 3 angeordnet, in der die Aluminiumfolie 1 mit der Kunststoffolie 2 verbunden wird. Mittels der Transportvorrichtung 5 wird somit der aus Kunststoffolie 2 und Aluminiumfolie 1 bestehende Folienverbund weiterbewegt.Before the transport device 5, the sealing device 3 is arranged, in which the aluminum foil 1 is connected to the plastic film 2. By means of the transport device 5, the film composite consisting of plastic film 2 and aluminum foil 1 is thus moved further.

Die beiden Folien 1, 2 werden mittels der Transportvorrichtung 5 jeweils solange vorwärts bewegt, bis sich die durch die Vorderkante einer jeweils ersten Vertiefung gebildete Markierung 2a jeweils an einem Fixpunkt T0 der Siegelstation 3 befindet. Das heißt, die beiden Folien 1, 2 werden jeweils solange weiterbewegt, bis sich die Vorderkante 2a der ersten Vertiefung der nächsten Gruppe von Vertiefungen 2b am Fixpunkt T0 befindet. Da die Vorderkanten 2a sich in einem vorbestimmten Abstand A2 zueinander befinden, werden beide Folien 1, 2 jeweils um den vorbestimmten Abstand A2 weiterbewegt.The two films 1, 2 are each moved forward by means of the transport device 5 until the mark 2a formed by the front edge of a respective first recess is located at a respective fixed point T0 of the sealing station 3. That is, the two sheets 1, 2 are each continued until the leading edge 2a of the first recess of the next group of recesses 2b is at the fixed point T0. Since the leading edges 2a are at a predetermined distance A2 to each other, both films 1, 2 are each moved by the predetermined distance A2.

Die Tänzerwalze 10 und die Offsetwalze 6 sind so angeordnet, daß sie gegeneinander zu - und voneinander weg bewegt werden können. Während die Offsetwalze 6 feststellbar ist und nur mittels Verstelleinheit 6a bewegbar ist, ist die Tänzerwalze 10 frei beweglich.The dancer roller 10 and the offset roller 6 are arranged so that they can be moved towards and away from each other. While the offset roller 6 can be detected and is movable only by means of adjustment unit 6a, the dancer roller 10 is freely movable.

In Transportrichtung der Kunststoffolie 2 ist hinter dem Prägewerkzeug 15 ein Sensor 7 angeordnet, mittels welchem die durch die Vorderkante einer jeweils ersten Vertiefung 2b gebildeten Markierung 2a erfaßbar ist. Erfaßt der Sensor 7 eine Vorderkante 2a der ersten Vertiefung einer Gruppe von Vertiefungen 2b, gibt er ein Signal ab. Der Sensor 7 ist so angeordnet, daß die Länge der zwischen dem Fixpunkt T0 und dem Referenzpunkt des Sensors 7 befindlichen Kunststoffolie 2 einem vorbestimmten Vielfachen des Abstands A2 der Markierungen 2a entspricht.In the transport direction of the plastic film 2, a sensor 7 is arranged behind the embossing tool 15, by means of which the mark 2a formed by the front edge of a respective first recess 2b can be detected. If the sensor 7 detects a front edge 2a of the first recess of a group of depressions 2b, it emits a signal. The sensor 7 is arranged so that the length of the located between the fixed point T0 and the reference point of the sensor 7 plastic film 2 corresponds to a predetermined multiple of the distance A2 of the markers 2a.

Wird der aus den beiden Folien 1, 2 bestehende Folienverbund mittels der Transportvorrichtung 5 weiterbewegt, wird eine entsprechende Länge der Folie 2 durch das Prägewerkzeug 15 transportiert. Des weiteren wird dieselbe Länge der Aluminiumfolie 1 durch den Drucker 4 transportiert. Hierzu wird das erste Transportelement 11 entsprechend dem vom zweiten Geber 12a des zweiten Transportelements 12 abgegebenen Signals angetrieben. Die Bewegung der Aluminiumfolie 1 durch den Drucker 4 erfolgt somit synchron zu der Bewegung der Kunststoffolie 2 durch das Prägewerkzeug 15. Das heißt, bei entsprechender Anordnung des Sensors 7 entspricht die Länge der sich zwischen dem Fix punkt T0 und dem Referenzpunkt T1 des Druckers 4 befindlichen ersten Folie 1 der Länge der sich zwischen dem Fixpunkt T0 und dem Sensor 7 befindlichen zweiten Folie 2.If the film composite consisting of the two films 1, 2 is moved further by means of the transport device 5, a corresponding length of the film 2 is transported by the embossing tool 15. Furthermore, the same length of the aluminum foil 1 is transported by the printer 4. This will be the first Transport element 11 is driven in accordance with the output from the second encoder 12a of the second transport element 12 signal. The movement of the aluminum foil 1 by the printer 4 is thus synchronized with the movement of the plastic film 2 by the embossing tool 15. That is, with a corresponding arrangement of the sensor 7 corresponds to the length of the point fixed between the T0 and the reference point T1 of the printer 4 first film 1 of the length of the second film 2 located between the fixed point T0 and the sensor 7.

Wird vom Sensor 7 eine die Markierung 2a bildende erste Vertiefung einer Gruppe von Vertiefungen 2b der Kunststoffolie 2 detektiert, wird das am Ausgang 7a des Sensors 7 liegende Signal von der Steuerung 16 an den Eingang 4a des Druckers 4 gelegt. Hierdurch druckt der Drucker 4 auf die Aluminiumfolie 1 relativ zur Markierung 2a positionsgenau ein Bild.If the sensor 7 detects a mark 2a forming a first recess of a group of recesses 2b of the plastic film 2, the signal lying at the output 7a of the sensor 7 is applied by the controller 16 to the input 4a of the printer 4. As a result, the printer 4 prints on the aluminum foil 1 relative to the mark 2 a positionally accurate an image.

Verändert sich der Abstand A2 der Markierungen 2a der Kunststoffolie 2 um eine Differenz, wie dies beispielsweise beim Stillstand der Vorrichtung durch Temperatureinwirkung durch eine Dehnung oder Schrumpfung der Kunststoffolie 2 geschehen kann, detektiert der Sensor 7 die Markierung 2a entsprechend später oder früher, so daß auch der Druckvorgang entsprechend später oder früher stattfindet. Hierdurch bleibt die Position des Druckbildes der Aluminiumfolie 1 relativ zu der Position der Vertiefungen 2b der Kunststoffolie 2 erhalten.If the distance A2 of the markings 2a of the plastic film 2 changes by a difference, as may occur, for example, when the device is at standstill due to the effect of temperature due to stretching or shrinking of the plastic film 2, the sensor 7 detects the mark 2a correspondingly later or earlier, so that also the printing process takes place later or earlier. As a result, the position of the printed image of the aluminum foil 1 relative to the position of the depressions 2b of the plastic film 2 is maintained.

Wird mittels der beiden Geber 11a, 12a festgestellt, daß die Länge der durch den Drucker 4 transportierte Aluminiumfolie 1 geringer ist, als die mittels der Transportvorrichtung 3 transportierte Länge, so verzögert die Steuerung 16 das vom Sensor 7 abgegebene Signal solange, bis die Längen übereinstimmen, was bedeutet, daß die Länge der sich zwischen dem Fixpunkt T0 der Siegelstation 3 und dem Drucker 4 befindliche Aluminiumfolie 1 genauso lang ist, wie die sich zwischen dem Fixpunkt T0 der Siegelstation 3 und dem Sensor 7 befindliche Kunststoffolie 2.If it is determined by means of the two encoders 11a, 12a that the length of the aluminum foil 1 transported by the printer 4 is less than the length transported by the transport device 3, the controller 16 delays the signal emitted by the sensor 7 until the lengths match , which means that the length of the aluminum foil 1 located between the fixed point T0 of the sealing station 3 and the printer 4 is the same length as the plastic foil 2 located between the fixed point T0 of the sealing station 3 and the sensor 7.

Wenngleich die Erfindung im wesentlichen auch anhand einer aus der DE 195 25 713 C1 bekannten Druckvorrichtung beschrieben wurde, so sind ihre Einsatzmöglichkeiten nicht auf die Verwendung einer derartigen Druckvorrichtung beschränkt. Sofern es sich bei den beiden Materialsträngen überhaupt um zwei miteinander zu verbindende Folien handelt, bei denen auf eine Folie ein Druckbild aufgebracht wird, kann dieses Druckbild mit jeder beliebigen Druckvorrichtung, insbesondere mit einem sogenannten Plattendrucker, Flexodrucker oder Siebdrucker aufgebracht werden.Although the invention essentially also with reference to one of DE 195 25 713 C1 known printing device has been described, so their uses are not limited to the use of such a printing device. If the two material strands are at all two films to be joined together, in which a printed image is applied to a film, this print image can be applied with any printing device, in particular with a so-called plate printer, flexoprinter or screen printer.

Des weiteren ist es nicht erforderlich, daß der abschnittsweise Weitertransport der beiden Materialstränge diskontinuierlich erfolgt. Die Erfindung läßt sich ebenso bei einer Anordnung verwenden, bei welcher beispielsweise entsprechend der DE 198 50 275 A1 die Materialstränge kontinuierlich weiterbewegt werden.Furthermore, it is not necessary that the section-wise further transport of the two strands of material takes place discontinuously. The invention can also be used in an arrangement in which, for example, according to the DE 198 50 275 A1 the material strands are continuously moved.
