Definitions

  • the present invention relates to an apparatus and a method for coating an optically readable data carrier, and to an optically readable data carrier.
  • Optical media such as B. CD's, as well as methods and devices for producing the same are well known in the art.
  • Such data carriers generally have a data-carrying surface which must be protected against environmental conditions.
  • a hardening lacquer was used, which was applied in a central area to the rapidly rotating data carrier in order to flow outwards by the centrifugal force and to form an essentially uniform layer on the CD.
  • the data carrier must be rotated at a high speed in order to generate sufficient centrifugal forces for an even distribution of the lacquer on the surface to be protected. This process involves the risk of damage to the data carrier.
  • excess paint is thrown off the data carrier in this method, which subsequently has to be disposed of in a complex manner.
  • EP-A-0 855 703 also discloses a method for gluing two essentially identical disk-shaped substrates of a data carrier with a double-sided adhesive film.
  • the present invention is based on the object of providing a simplified and inexpensive method for coating an optically readable data carrier and a data carrier produced in this way.
  • This object is achieved in a method for coating an optically readable data carrier in that a one-sided adhesive, transparent adhesive film is applied to a surface of the data carrier to be protected.
  • the use of an adhesive film has the advantage that the above-mentioned centrifuging process for coating the data carrier with a lacquer is omitted and no lacquer residues which have to be disposed of in a complex manner are thrown off.
  • the adhesive film also provides a simple and inexpensive solution for coating a data carrier.
  • the adhesive film is removed from a carrier film during or after being applied to the data carrier.
  • the backing film has the advantage that the film is protected from being applied to the data carrier and gives the adhesive film sufficient stability for transport.
  • a protective film is preferably removed from the adhesive film before the adhesive film is applied to the data carrier and protects the one-sided adhesive surface of the adhesive film from contamination and damage prior to the application process.
  • the shape and size of the adhesive film corresponds to the surface of the data medium to be protected, in order to cover it completely.
  • sections of the adhesive film corresponding to the shape and size of the data carrier are advantageously punched out on the carrier film.
  • the adhesive film is preferably applied centered on the surface of the data carrier to be protected, in order to ensure a uniform coating of all areas of the data carrier.
  • the adhesive film and the data carrier are preferably aligned with one another before application.
  • the adhesive film is applied to the data carrier by means of a rotating pressure roller during the application pressed, which ensures a secure contact between the adhesive film and the data carrier.
  • the contact pressure of the pressure roller is preferably controlled in order to achieve an optimal adhesive effect on the surface of the data carrier.
  • the adhesive film is preferably held at a predetermined angle to the surface of the data carrier before being pressed on by the pressure roller, in order to keep the adhesive film at a distance from the data carrier and to ensure controlled pressing only in the area of the pressure roller. This ensures that air pockets between the adhesive film and the surface of the data carrier are avoided.
  • the data carrier and the pressure roller are moved relative to one another in order to enable the adhesive film to be applied progressively to the surface of the data carrier.
  • the data carrier is moved linearly past the pressure roller, and the pressure roller is advantageously rotated synchronously with the movement of the data carrier in order to continuously press the adhesive film onto the data carrier.
  • the adhesive film is cured after being applied to the optical data carrier in order to provide increased strength and thus improved protection of the optical data carrier.
  • the adhesive film is preferably cured by thermal treatment and / or pressure and / or time.
  • the adhesive film is advantageously cured by UV radiation.
  • a transparent protective layer in particular a so-called PC tape, is preferably applied to the side of the adhesive film that is not glued to the data carrier.
  • the object on which the invention is based is also achieved by a device for coating an optically readable data carrier with a lamina. Removal station for applying a one-sided adhesive, transparent adhesive film to a surface of the data medium to be protected.
  • an optically readable data carrier with a transparent protective layer in which the protective layer is a one-sided adhesive film.
  • the protective layer is a one-sided adhesive film.
  • the data carrier is arranged in a protective housing which surrounds the data carrier.
  • Figure 1 is a schematic representation of an apparatus for producing optical data carriers according to the invention.
  • Fig. 2 is a schematic view of parts of a laminating station according to the present invention.
  • FIG. 3 is a side view of an alternative embodiment of a laminating station according to the invention.
  • Fig. 4 is a schematic side view of an alternative adhesive film.
  • FIG. 1 shows a device 1 for producing an optical data carrier with at least one surface to be protected.
  • the device has a feed unit 3 for feeding an optical data carrier, such as a CD or a DVR.
  • an optical data carrier such as a CD or a DVR.
  • the data carrier 6 is conveyed to a laminating station 7, which is described in greater detail with reference to FIGS. 2 and 3.
  • a pressure-sensitive adhesive tape or film which is adhesive on one side and is known as PSA tape, is applied to the surface of the optical data carrier 6 to be protected.
  • the term adhesive tape or film is to be understood as a layer made of an adhesive without a carrier material.
  • the optical properties of an adhesive layer can usually be controlled more precisely and better than that of a coated carrier material.
  • the adhesive film has different adhesion properties depending on the pressure applied to it.

Description

Vorrichtung und Verfahren zum Beschichten eines optisch lesbaren Datenträgers Device and method for coating an optically readable data carrier
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zum Beschichten eines optisch lesbaren Datenträgers, sowie auf einen optisch lesbaren Datenträger.The present invention relates to an apparatus and a method for coating an optically readable data carrier, and to an optically readable data carrier.
Optische Datenträger, wie z. B. CD's, sowie Verfahren und Vorrichtungen zur Herstellung desselben sind in der Technik zahlreich bekannt. Derartige Da- tenträger besitzen in der Regel eine Daten tragende Oberfläche, welche gegenüber Umweltbedingungen geschützt werden muß. Um die Oberfläche zu schützen, wurde in der Vergangenheit ein aushärtender Lack verwendet, der in einem Mittelbereich auf den sich rasch drehenden Datenträger aufgebracht wurde, um durch die Zentrifugalkraft nach außen zu fließen und eine im we- sentlichen gleichmäßige Schicht auf der CD zu bilden. Dabei muß der Datenträger jedoch mit einer hohen Geschwindigkeit gedreht werden, um ausreichende Zentrifugalkräfte für einen gleichmäßige Verteilung des Lacks auf der zu schützenden Oberfläche zu erzeugen. Dieser Vorgang birgt die Gefahr einer Beschädigung des Datenträgers in sich. Darüber hinaus wird bei diesem Verfahren überschüssiger Lack von dem Datenträger abgeschleudert, der nachfolgend aufwendig entsorgt werden muß.Optical media, such as B. CD's, as well as methods and devices for producing the same are well known in the art. Such data carriers generally have a data-carrying surface which must be protected against environmental conditions. In the past, to protect the surface, a hardening lacquer was used, which was applied in a central area to the rapidly rotating data carrier in order to flow outwards by the centrifugal force and to form an essentially uniform layer on the CD. However, the data carrier must be rotated at a high speed in order to generate sufficient centrifugal forces for an even distribution of the lacquer on the surface to be protected. This process involves the risk of damage to the data carrier. In addition, excess paint is thrown off the data carrier in this method, which subsequently has to be disposed of in a complex manner.
Aus der EP-A-0 855 703 ist ferner ein Verfahren zum Verkleben von zwei im wesentlichen gleichen scheibenförmigen Substraten eines Datenträgers mit einer zweiseitig klebenden Klebefolie bekannt.EP-A-0 855 703 also discloses a method for gluing two essentially identical disk-shaped substrates of a data carrier with a double-sided adhesive film.
Ausgehend von diesem Verfahren liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein vereinfachtes und kostengünstiges Verfahren zum Beschichten eines optisch lesbaren Datenträgers sowie einen derart hergestell- ten Datenträger vorzusehen. Diese Aufgabe wird erfindungsgemäß bei einem Verfahren zum Beschichten eines optisch lesbaren Datenträgers dadurch gelöst, daß eine einseitig klebende, transparente Klebefolie auf eine zu schützende Oberfläche des Datenträgers aufgebracht wird. Die Verwendung einer Klebefolie besitzt den Vorteil, daß der oben genannte Schleudervorgang zum Beschichten des Datenträgers mit einem Lack entfällt und keine abgeschleuderten Lackreste, die aufwendig entsorgt werden müssen, entstehen. Die Klebefolie sieht ferner eine einfache und kostengünstige Lösung für die Beschichtung eines Datenträgers vor.Based on this method, the present invention is based on the object of providing a simplified and inexpensive method for coating an optically readable data carrier and a data carrier produced in this way. This object is achieved in a method for coating an optically readable data carrier in that a one-sided adhesive, transparent adhesive film is applied to a surface of the data carrier to be protected. The use of an adhesive film has the advantage that the above-mentioned centrifuging process for coating the data carrier with a lacquer is omitted and no lacquer residues which have to be disposed of in a complex manner are thrown off. The adhesive film also provides a simple and inexpensive solution for coating a data carrier.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird die Klebefolie während oder nach dem Aufbringen auf dem Datenträger von einer Trägerfolie abgezogen. Die Trägerfolie besitzt den Vorteil, daß die Folie vor ihrem Aufbringen auf den Datenträger geschützt ist und der Klebefolie eine ausrei- chende Stabilität für einen Transport gibt. Zusätzlich wird vorzugsweise vor dem Aufbringen der Klebefolie auf dem Datenträger eine Schutzfolie von der Klebefolie abgezogen, welche vor dem Aufbringvorgang die einseitig klebende Oberfläche der Klebefolie vor Verunreinigungen sowie Beschädigungen schützt.According to a preferred embodiment of the invention, the adhesive film is removed from a carrier film during or after being applied to the data carrier. The backing film has the advantage that the film is protected from being applied to the data carrier and gives the adhesive film sufficient stability for transport. In addition, a protective film is preferably removed from the adhesive film before the adhesive film is applied to the data carrier and protects the one-sided adhesive surface of the adhesive film from contamination and damage prior to the application process.
Vorteilhafterweise entspricht die Form und Größe der Klebefolie der zu schützenden Oberfläche des Datenträgers, um diesen vollständig abzudecken. Dabei sind vorteilhafterweise der Form und Größe des Datenträgers entsprechende Abschnitte der Klebefolie auf der Trägerfolie ausgestanzt.Advantageously, the shape and size of the adhesive film corresponds to the surface of the data medium to be protected, in order to cover it completely. In this case, sections of the adhesive film corresponding to the shape and size of the data carrier are advantageously punched out on the carrier film.
Vorzugsweise wird die Klebefolie zentriert auf die zu schützende Oberfläche des Datenträgers aufgebracht, um eine gleichmäßige Beschichtung aller Bereiche des Datenträgers sicherzustellen. Hierzu werden die Klebefolie und der Datenträger vorzugsweise vor dem Aufbringen zueinander ausgerichtet.The adhesive film is preferably applied centered on the surface of the data carrier to be protected, in order to ensure a uniform coating of all areas of the data carrier. For this purpose, the adhesive film and the data carrier are preferably aligned with one another before application.
Bei einer weiteren Ausführungsform der Erfindung wird die Klebefolie während des Aufbringens über eine sich drehende Andrückrolle auf den Datenträger gedrückt, die einen sicheren Kontakt zwischen der Klebefolie und dem Datenträger sicherstellt. Dabei wird der Anpreßdruck der Andrückrolle vorzugsweise gesteuert, um eine optimale Klebewirkung auf der Oberfläche des Datenträgers zu erreichen.In a further embodiment of the invention, the adhesive film is applied to the data carrier by means of a rotating pressure roller during the application pressed, which ensures a secure contact between the adhesive film and the data carrier. The contact pressure of the pressure roller is preferably controlled in order to achieve an optimal adhesive effect on the surface of the data carrier.
Vorzugsweise wird die Klebefolie vor dem Andrücken durch die Andrückrolle unter einem vorgegebenen Winkel zur Oberfläche des Datenträgers gehalten, um die Klebefolie beabstandet vom Datenträger zu halten, und ein kontrolliertes Andrücken ausschließlich im Bereich der Andrückrolle sicherzustellen. Hierdurch wird erreicht, daß Lufteinschlüsse zwischen der Klebefolie und der Oberfläche des Datenträgers vermieden werden.The adhesive film is preferably held at a predetermined angle to the surface of the data carrier before being pressed on by the pressure roller, in order to keep the adhesive film at a distance from the data carrier and to ensure controlled pressing only in the area of the pressure roller. This ensures that air pockets between the adhesive film and the surface of the data carrier are avoided.
Gemäß einer bevorzugten Ausführungsform der Erfindung werden der Datenträger und die Andrückrolle relativ zueinander bewegt, um ein fortschreitendes Aufbringen der Klebefolie auf der Oberfläche des Datenträgers zu ermöglichen. Vorteilhafterweise wird dabei der Datenträger linear an der Andrückrolle vorbeibewegt, und die Andrückrolle wird vorteilhafterweise synchron mit der Bewegung des Datenträgers gedreht, um die Klebefolie fortlaufend auf den Datenträger zu drücken.According to a preferred embodiment of the invention, the data carrier and the pressure roller are moved relative to one another in order to enable the adhesive film to be applied progressively to the surface of the data carrier. Advantageously, the data carrier is moved linearly past the pressure roller, and the pressure roller is advantageously rotated synchronously with the movement of the data carrier in order to continuously press the adhesive film onto the data carrier.
Gemäß einer Ausführungsform der Erfindung wird die Klebefolie nach dem Aufbringen auf den optischen Datenträger ausgehärtet, um eine erhöhte Festigkeit und somit einen verbesserten Schutz des optischen Datenträgers vorzusehen. Dabei wird die Klebefolie vorzugsweise durch thermische Behand- lung und/oder Druck und/oder Zeit ausgehärtet. Bei einer alternativen Ausführungsform der Erfindung wird die Klebefolie vorteilhafterweise durch UV- Strahlung ausgehärtet.According to one embodiment of the invention, the adhesive film is cured after being applied to the optical data carrier in order to provide increased strength and thus improved protection of the optical data carrier. The adhesive film is preferably cured by thermal treatment and / or pressure and / or time. In an alternative embodiment of the invention, the adhesive film is advantageously cured by UV radiation.
Vorzugsweise ist eine transparente Schutzschicht, insbesondere ein soge- nanntes PC-Tape, auf der nicht mit dem Datenträger verklebten Seite der Klebefolie aufgebracht.A transparent protective layer, in particular a so-called PC tape, is preferably applied to the side of the adhesive film that is not glued to the data carrier.
Die der Erfindung zugrundeliegende Aufgabe wird auch durch eine Vorrichtung zum Beschichten eines optisch lesbaren Datenträgers mit einer Lami- nierstation zum Aufbringen einer einseitig klebenden, transparenten Klebefolie auf eine zu schützende Oberfläche des Datenträgers gelöst. Bei einer derartigen Vorrichtung werden die oben bezüglich des Verfahrens genannten Vorteile erreicht. Insbesondere entfällt bei einer derartigen Vorrichtung die Gefahr der Beschädigung des Datenträgers durch den Schleudervorgang, und ferner entfällt die aufwendige Aufbearbeitung und Entsorgung von abgeschleuderten Lackresten.The object on which the invention is based is also achieved by a device for coating an optically readable data carrier with a lamina. Removal station for applying a one-sided adhesive, transparent adhesive film to a surface of the data medium to be protected. With such a device, the advantages mentioned above with regard to the method are achieved. In particular, in the case of such a device, there is no risk of damage to the data carrier by the centrifuging process, and there is also no need for the time-consuming processing and disposal of spilled lacquer residues.
Die Aufgabe wird ferner durch einen optisch lesbaren Datenträger mit einer transparenten Schutzschicht gelöst, bei der die Schutzschicht eine einseitig klebende Klebefolie ist. Die Verwendung einer einseitig klebenden, transparenten Klebefolie als Schutzschicht führt zu den schon oben genannten Vorteilen. Gemäß einer derzeitig bevorzugten Ausführungsform der Erfindung ist der Datenträger in einem Schutzgehäuse angeordnet, welches den Datenträ- ger umgibt. Durch die Verwendung eines Schutzgehäuses werden die Anforderungen an die Schutzschicht stark verringert, da diese keine stärkeren Belastungen abhalten muß, sondern hauptsächlich als Schutzschicht gegen Verschmutzungen und chemikalische Einflüsse dient.The object is further achieved by an optically readable data carrier with a transparent protective layer, in which the protective layer is a one-sided adhesive film. The use of a one-sided adhesive, transparent adhesive film as a protective layer leads to the advantages already mentioned above. According to a currently preferred embodiment of the invention, the data carrier is arranged in a protective housing which surrounds the data carrier. By using a protective housing, the requirements for the protective layer are greatly reduced, since this does not have to withstand heavy loads, but mainly serves as a protective layer against dirt and chemical influences.

Figur 1 zeigt eine Vorrichtung 1 zur Herstellung eines optischen Datenträgers mit wenigstens einer zu schützenden Oberfläche. Die Vorrichtung weist eine Zuführeinheit 3 für die Zuführung eines optischen Datenträgers, wie beispielsweise einer CD oder einer DVR, auf. Aus der ersten Zuführeinheit 3 wird der Datenträger 6 zu einer Laminierstation 7 befördert, welche in größerer Einzelheit unter Bezugnahme auf die Figuren 2 und 3 beschrieben wird. In der Laminierstation wird ein einseitig klebendes, druckempfindliches Klebeband bzw. eine -folie, die als PSA-Tape bekannt ist, auf die zu schützende Oberfläche des optischen Datenträgers 6 aufgebracht. Dabei ist unter dem Begriff Klebeband bzw. -folie eine Schicht aus einem Kleber ohne ein Trägermaterial zu verstehen. Die optischen Eigenschaften einer Kle- beschicht lassen sich in der Regel genauer und besser kontrollieren, als die eines beschichteten Trägermaterials. Die Klebefolie weist abhängig von dem daran angelegten Druck unterschiedliche Adhäsionseigenschaften auf. Anschließend wird der Datenträger auf einem Rundtisch 8 mit einer Zentrier- und Halteeinrichtung abgelegtFIG. 1 shows a device 1 for producing an optical data carrier with at least one surface to be protected. The device has a feed unit 3 for feeding an optical data carrier, such as a CD or a DVR. From the first feed unit 3, the data carrier 6 is conveyed to a laminating station 7, which is described in greater detail with reference to FIGS. 2 and 3. In the laminating station, a pressure-sensitive adhesive tape or film, which is adhesive on one side and is known as PSA tape, is applied to the surface of the optical data carrier 6 to be protected. The term adhesive tape or film is to be understood as a layer made of an adhesive without a carrier material. The optical properties of an adhesive layer can usually be controlled more precisely and better than that of a coated carrier material. The adhesive film has different adhesion properties depending on the pressure applied to it. The data carrier is then placed on a rotary table 8 with a centering and holding device
Anschließend wird der Rundtisch weiter gedreht, bis er in einer Prozeßstation 11 angeordnet ist, in der die auf dem Datenträger befindliche Klebefolie ausgehärtet wird. Dann wird der Rundtisch zu einer Entladeposition gedreht, wo der optische Datenträger entnommen wird.The rotary table is then rotated further until it is arranged in a process station 11 in which the adhesive film on the data carrier is cured. The rotary table is then rotated to an unloading position, where the optical data carrier is removed.
Die Vorrichtung 1 ist in einem Reinraum angeordnet, in dem die jeweiligen Arbeitsschritte unter Reinstraumbedingungen durchgeführt werden können.The device 1 is arranged in a clean room in which the respective work steps can be carried out under clean room conditions.
Die Figuren 2 und 3 zeigen schematische Darstellungen einer Laminierstation 7 gemäß der vorliegenden Erfindung, wobei die in Figur 2 und 3 gezeigten Laminierstationen 7 zum Teil unterschiedliche Anordnungen der jeweiligen Bauteile aufweisen. In der folgenden Beschreibung der Laminierstationen gemäß den Figuren 2 und 3 werden jedoch dieselben Bezugszeichen verwendet, soweit identische bzw. gleichartige Bauteile betroffen sind.FIGS. 2 and 3 show schematic representations of a laminating station 7 according to the present invention, the laminating stations 7 shown in FIGS. 2 and 3 partly having different arrangements of the respective components. In the following description of the laminating stations according to FIGS. 2 and 3, however, the same reference numerals are used insofar as identical or similar components are concerned.
Die Laminierstation 7 weist eine Zuführrolle 22 auf, auf die eine bandförmige Laminierfolie 23 aufgerollt ist. Die Laminierfolie 23 besteht aus insgesamt drei Folien, nämlich einer Schutzfolie 24, einer einseitig klebenden Klebefolie 25 und einer Trägerfolie 26, wie am besten in dem vergrößerten Kreisausschnitt in Figur 2 zu erkennen ist. Die Klebefolie 25 weist Abschnitte 27 auf, die entsprechend der Größe und Form einer zu beschichtenden Oberseite des Datenträgers 6 ausgestanzt sind.The laminating station 7 has a feed roller 22 on which a band-shaped laminating film 23 is rolled up. The laminating film 23 consists of a total of three films, namely a protective film 24, an adhesive film 25 that is adhesive on one side and a carrier film 26, as can best be seen in the enlarged circular section in FIG. 2. The adhesive film 25 has sections 27 which are punched out in accordance with the size and shape of an upper side of the data carrier 6 to be coated.
Die Laminierstation weist ferner eine Aufnahmerolle 28 auf, auf die Reste der Laminierfolie 23 nach einem Laminiervorgang aufgenommen werden. Zwischen der Zuführrolle 22 und der Aufnahmerolle 28 ist die Laminierfolie 23 um eine Vielzahl von Rollen 30 bis 38 geführt, um einen definierten Bewegungs- pfad der bandförmigen Laminierfolie 23 zwischen den Rollen 22 und 28 vorzusehen. Die jeweiligen Rollen 30 bis 38 sind um ihre jeweilige Drehachse drehbar, und die Rollen 31 und 37 sind als sogenannte Tänzerrollen ausgebildet, welche in Horizontalrichtung beweglich gelagert sind, um einen Längenausgleich der Laminierfolie 23 zwischen den Rollen 22 und 28 zu ermögli- chen. Hierdurch können die Rollen 22 und 28 trotz diskontinuierlicher Lami- nierzyklen, wie nachfolgend beschrieben wird, mit konstanter Geschwindigkeit gedreht werden. Die nicht benötigten Teile der Klebefolie 25 können vorab, d. h. vor dem Einführen der Laminierfolie in die Laminierstation, z. B. bei der Herstellung der Laminierfolie, entfernt werden, oder sie können an der Folie verbleiben, um eine gleichmäßige Dicke der Folie 23 über die gesamte Breite und Länge derselben, zumindest vor einem Laminiervorgang, sicherzustellen.The laminating station also has a take-up roll 28, on which remnants of the laminating film 23 are picked up after a laminating process. The laminating film 23 is guided around a multiplicity of rolls 30 to 38 between the feed roll 22 and the take-up roll 28 in order to provide a defined path of movement of the band-shaped laminating film 23 between the rolls 22 and 28. The respective rollers 30 to 38 can be rotated about their respective axes of rotation, and the rollers 31 and 37 are designed as so-called dancer rollers, which are movably mounted in the horizontal direction in order to enable a length compensation of the laminating film 23 between the rollers 22 and 28. As a result, the rollers 22 and 28 can be rotated at a constant speed despite discontinuous laminating cycles, as will be described below. The parts of the adhesive film 25 that are not required can be pre-d. H. before inserting the laminating film into the laminating station, e.g. B. in the manufacture of the laminating film, or they can remain on the film to ensure a uniform thickness of the film 23 over the entire width and length thereof, at least before a lamination process.
Die Laminierfolie 23 ist um ein keilförmiges Rakel 40 geführt, an dem die Laminierfolie 23 scharf umgelenkt wird, um ein Abziehen der Schutzfolie 24 von der Laminierfolie 23 zu ermöglichen, so daß die klebende Seite der Klebefolie 25 zum Verkleben mit dem optischen Datenträger 6 freigelegt wird. Das Abziehen der Schutzfolie 24 ist am besten in Figur 3 zu erkennen. Die Schutzfolie 24 wird nach dem Abziehen auf eine nicht näher dargestellten Rolle aufgerollt. Anstelle des keilförmigen Rakels kann auch eine alternative Form einer Folien-Abzieheinrichtung verwendet werden.The laminating film 23 is guided around a wedge-shaped squeegee 40 on which the laminating film 23 is deflected sharply in order to enable the protective film 24 to be pulled off the laminating film 23, so that the adhesive side of the adhesive film 25 is exposed for gluing to the optical data carrier 6 . The removal of the protective film 24 can best be seen in FIG. 3. The protective film 24 is rolled up on a roll, not shown, after removal. Instead of the wedge-shaped doctor blade, an alternative form of a film pulling device can also be used.
Nachdem die Laminierfolie 23 um das Rakel 40 geführt ist, wird es unter einem Winkel bezüglich einer Horizontalen um die tiefer liegende Rolle 33 ge- führt, welche als Andrückrolle ausgebildet ist. Nach der Rolle 33 wird die Laminierfolie 23 um die Welle 34 geführt, welche über einen Motor 42 angetrieben wird.After the laminating film 23 has been guided around the doctor blade 40, it is wrapped around the lower lying roller 33 at an angle with respect to a horizontal leads, which is designed as a pressure roller. After the roll 33, the laminating film 23 is guided around the shaft 34, which is driven by a motor 42.
Dabei bewirkt eine Drehung der angetriebenen Rolle 34 eine entsprechende Drehung der Andrückrolle 33 sowie einer nachgeordneten Rolle 35, die als reine Führungsrolle ausgebildet ist.A rotation of the driven roller 34 causes a corresponding rotation of the pressure roller 33 and a downstream roller 35, which is designed as a pure guide roller.
Die Laminierstation 7 weist einen ersten Sensor 45 auf, der mit der angetrie- benen Rolle 34 assoziiert ist und in der Lage ist, Konturen der ausgestanzten Abschnitte 27 der Klebefolie 25 zu detektieren. Die Laminierfolie 23 wird über die angetriebene Rolle 34 in Längsrichtung hin und her gefahren, bis der Sensor 45 eine bestimmte Kontur des ausgestanzten Abschnitts 27, wie z. B. ein ausgestanztes Mittelloch, erkennt. Wenn der Sensor 45 das Mittelloch er- kennt, wird er durch Bewegung der Folie direkt über einer Kante des Mittellochs positioniert, wodurch eine genaue Ausrichtung des Abschnitts 27 bezüglich der Rolle 34 und insbesondere der Andrückrolle 33 in Längsrichtung der Laminierfolie 23 erreicht wird.The laminating station 7 has a first sensor 45, which is associated with the driven roller 34 and is able to detect contours of the punched-out sections 27 of the adhesive film 25. The laminating film 23 is moved back and forth in the longitudinal direction via the driven roller 34 until the sensor 45 has a specific contour of the punched-out section 27, such as, for example, B. recognizes a punched center hole. When the sensor 45 detects the center hole, it is positioned by moving the film directly over an edge of the center hole, as a result of which the section 27 is precisely aligned with respect to the roller 34 and in particular the pressure roller 33 in the longitudinal direction of the laminating film 23.
Die Laminierstation 7 weist ferner eine Auflage- und Transporteinheit 47 für den zu laminierenden Datenträger 6 auf. Die Auflage- und Transporteinheit 47 bildet eine horizontale Auflage für den Datenträger 6 und ist über geeignete, nicht näher dargestellte Bewegungsvorrichtungen in alle Richtungen bewegbar. Über einen versenkbaren Zentrierstift 48 wird eine genaue Ausrichtung des Datenträgers 6 auf der Auflage- und Transporteinheit 47 sichergestellt. Der Stift 48 ist während des Laminiervorgangs versenkbar, um ihn nicht zu beeinträchtigen. Dies wird dadurch erreicht, daß er durch eine Feder mit relativ geringer Federkraft nach oben in die in Figur 3 gezeigte Position gedrückt wird. Bei einem Druck von oben auf den Stift wird er entgegen der Federkraft nach unten gedrückt. Alternativ kann der Stift auch über einen Zylinder oder einen Motor bewegt werden.The laminating station 7 also has a support and transport unit 47 for the data carrier 6 to be laminated. The support and transport unit 47 forms a horizontal support for the data carrier 6 and can be moved in all directions by means of suitable movement devices, not shown. A retractable centering pin 48 ensures precise alignment of the data carrier 6 on the support and transport unit 47. The pin 48 is retractable during the lamination process in order not to interfere with it. This is achieved in that it is pressed upwards into the position shown in FIG. 3 by a spring with a relatively low spring force. When the pen is pressed from above, it is pressed down against the spring force. Alternatively, the pin can also be moved via a cylinder or a motor.
Vor dem Laminieren des Datenträgers 6 wird die Transport- und Auflageeinheit 47 in X-Richtung, welche der Längsrichtung der Laminierfolie 23 ent- spricht, gegen einen Anschlag gefahren. Hierdurch wird sichergestellt, daß der Datenträger 6 und der zuvor in Längsrichtung ausgerichtete Abschnitt 27 der Klebefolie 25 zueinander ausgerichtet sind. Anschließend wird die Transport- und Auflageeinheit 47 in Z-Richtung, die quer zur Längsrichtung der Laminierfolie 23 verläuft, hin und her gefahren. Über ein der Transport- und Auflageeinheit 47 zugeordnetes Sensorpaar 50 wird eine Kontur, wie beispielsweise die Kontur eines Mittellochs, des ausgestanzten Abschnitts 27 der Klebefolie 25 detektiert, was eine seitliche Ausrichtung des Datenträgers 6 bezüglich des Abschnitts 27 ermöglicht.Before the data carrier 6 is laminated, the transport and support unit 47 is moved in the X direction, which corresponds to the longitudinal direction of the laminating film 23. speaks, driven against an attack. This ensures that the data carrier 6 and the section 27 of the adhesive film 25 previously aligned in the longitudinal direction are aligned with one another. The transport and support unit 47 is then moved back and forth in the Z direction, which runs transversely to the longitudinal direction of the laminating film 23. A contour, such as the contour of a center hole, of the punched-out section 27 of the adhesive film 25 is detected via a pair of sensors 50 assigned to the transport and support unit 47, which enables the data carrier 6 to be aligned laterally with respect to the section 27.
Nachdem der Datenträger 6 in obiger Weise sowohl in X-Richtung als auch in Z-Richtung bezüglich des Abschnitts 27 der Klebefolie 25 ausgerichtet ist, wird die Transport- und Auflageeinheit 47 in Y-Richtung hochgefahren. Nun wird die Rolle 34 über den Motor 42 angetrieben, was bewirkt, daß sich die Laminierfolie 23 in X-Richtung bewegt. Gleichzeitig und synchronisiert mit der Drehung wird die Transport- und Auflageeinheit 47 in X-Richtung bewegt. Dabei kommt der Abschnitt 27 mit der zu schützenden Oberfläche des Datenträgers 6 in Kontakt und wird durch die Andrückrolle 33 so dagegen gepreßt, daß sie an dem Datenträger 6 anhaftet und sich von der Trägerfolie 26 löst. Durch die synchronisierte Bewegung der Antriebsrolle 34 mit der Transport- und Auflageeinheit 47 wird ein Abschnitt 27 der Klebefolie 25 zentriert auf den Datenträger 6 aufgebracht, so daß der Abschnitt 27 der Folie 25 die zu schützende Seite des Datenträgers 6 vollständig abdeckt und nicht über den Rand vorsteht. Der Anpreßdruck der Andrückrolle wird über die Position der Trans- port- und Auflageeinheit 47 in Y-Richtung gesteuert, um die Adhäsionseigenschaften der druckempfindlichen Klebefolie einzustellen. Alternativ kann natürlich auch die Andrückrolle 33 in Richtung der Transport- und Auflageeinheit bewegt werden. Für eine gute Einstellung bzw. einen guten Ausgleich des Anpreßdrucks kann ein gefedertes Aufhängungssystem vorgesehen werden. Die Aufhängung kann über eine Feder oder einen Druckluftzylinder erfolgen.After the data carrier 6 has been aligned in the above manner both in the X direction and in the Z direction with respect to the section 27 of the adhesive film 25, the transport and support unit 47 is raised in the Y direction. Now the roller 34 is driven by the motor 42, which causes the laminating film 23 to move in the X direction. Simultaneously and synchronized with the rotation, the transport and support unit 47 is moved in the X direction. The section 27 comes into contact with the surface of the data carrier 6 to be protected and is pressed against it by the pressure roller 33 in such a way that it adheres to the data carrier 6 and detaches from the carrier film 26. Due to the synchronized movement of the drive roller 34 with the transport and support unit 47, a section 27 of the adhesive film 25 is applied centered on the data carrier 6, so that the section 27 of the film 25 completely covers the side of the data carrier 6 to be protected and not over the edge protrudes. The contact pressure of the pressure roller is controlled via the position of the transport and support unit 47 in the Y direction in order to adjust the adhesive properties of the pressure-sensitive adhesive film. Alternatively, of course, the pressure roller 33 can also be moved in the direction of the transport and support unit. A spring-loaded suspension system can be provided for a good setting or a good compensation of the contact pressure. It can be suspended using a spring or a compressed air cylinder.
Anschließend wird der so mit dem Abschnitt 27 der Klebefolie 25 versehene Datenträger 6 über eine geeignete Handhabungsvorrichtung 52, wie bei- spielsweise einen Innenlochgreifer, von der Transport- und Auflageeinheit 47 entnommen und zu dem Rundtisch 8 gemäß Figur 1 transportiert.Subsequently, the data carrier 6 thus provided with the section 27 of the adhesive film 25 is moved via a suitable handling device 52, such as an inner hole gripper, for example, removed from the transport and support unit 47 and transported to the rotary table 8 according to FIG. 1.
Ein neuer Datenträger 6 wird auf die Transport- und Auflageeinheit 47 geladen, und der Vorgang wird wiederholt. Wie schon oben erwähnt, drehen sich die Rollen 22 und 28 kontinuierlich während des ganzen Vorgangs, obwohl der Klebevorgang diskontinuierlich abläuft. Der daher erforderliche Längenausgleich der Laminierfolie 23 wird, wie schon erwähnt, über eine Horizontalbewegung der Tänzerrollen 31 und 37 erreicht.A new data carrier 6 is loaded onto the transport and support unit 47 and the process is repeated. As mentioned above, the rollers 22 and 28 rotate continuously throughout the process, although the gluing process is discontinuous. The necessary length compensation of the laminating film 23 is, as already mentioned, achieved by a horizontal movement of the dancer rolls 31 and 37.
Obwohl die Laminierfolie gemäß obiger Beschreibung drei Schichten, nämlich eine Schutzfolie 24, eine Klebefolie 25 und eine Trägerfolie 26, aufweist, sei bemerkt, daß eine Schutzfolie 24 nicht zwingend notwendig ist. Falls jedoch keine Schutzfolie 24 verwendet wird, sollten wenigstens die Rollen 30 und 32 speziell beschichtet sein, um ein Verkleben der dann freiliegenden Klebefolie 25 an diesen Rollen zu verhindern.Although the laminating film has three layers, namely a protective film 24, an adhesive film 25 and a carrier film 26, as described above, it should be noted that a protective film 24 is not absolutely necessary. If, however, no protective film 24 is used, at least the rolls 30 and 32 should be specially coated in order to prevent the then exposed adhesive film 25 from sticking to these rolls.
Alternativ könnten auch die Führungsrollen, bis auf die Rolle 33, weggelassen werden, wobei in diesem Fall die Rollen 22 und 28 derart gesteuert werden müssen, daß eine Ausrichtung der Abschnitte 27 sowie eine mit der Transport- und Auflageeinheit 47 synchronisierte Bewegung der Laminierfolie 23 erreicht wird.Alternatively, the guide rollers, apart from the roller 33, could also be omitted, in which case the rollers 22 and 28 must be controlled such that an alignment of the sections 27 and a movement of the laminating film 23 synchronized with the transport and support unit 47 are achieved becomes.
Anstelle der Sensoren 45 und 50 könnte auch ein einzelner Sensor, wie bei- spielsweise eine Kamera, für die obigen Ausrichtungsvorgänge verwendet werden.Instead of sensors 45 and 50, a single sensor, such as a camera, could also be used for the above alignment processes.
Über den Rundtisch 8 wird der Datenträger 6, wie oben beschrieben, in die Prozeßstation 11 transportiert, in der die Klebefolie ausgehärtet wird.As described above, the data carrier 6 is transported via the rotary table 8 into the process station 11, in which the adhesive film is cured.
Figur 4 zeigt eine alternative Ausführungsform einer bandförmigen Laminierfolie, die in der oben genannten Laminierstation eingesetzt werden kann. In Figur 4 werden dieselben Bezugszeichen verwendet, sofern dieselben oder ähnliche Elemente bezeichnet werden. Die Laminierfolie 23 besteht wiederum aus drei Folien, nämlich einer Schutzfolie 24 einer einseitig klebenden Klebefolie 25 und einer Trägerfolie 26. Im Gegensatz zu dem zuvor beschriebenen Ausführungsbeispiel besteht die Klebefolie nicht aus einer einzigen Schicht eines Klebermaterials. Vielmehr ist die einseitig klebende Klebefolie 25 aus einer Kleberschicht 60 und einer Schutzschicht 62 wie beispielsweise einem PC-Tape aufgebaut. Durch das PC-Tape erhält die Klebefolie zusätzliche Stabilität und ferner weist das PC-Tape besondere optische Eigenschaften auf, die insbesondere bei einer DVR von Vorteil sind. Die Klebefolie 25 weist wie zuvor beschrieben Abschnitte auf, die entsprechend der Größe und Form einer zu verklebenden Oberseite des Datenträgers ausgestanzt sind. Bei dieser Art der Klebefolie kann die Prozeßstation 11 entfallen, da ein Aushärten der Klebefolie nicht notwendig ist.FIG. 4 shows an alternative embodiment of a band-shaped laminating film which can be used in the above-mentioned laminating station. The same reference numerals are used in FIG. 4 if they are the same or similar elements are referred to. The laminating film 23 in turn consists of three films, namely a protective film 24 of a single-sided adhesive film 25 and a carrier film 26. In contrast to the exemplary embodiment described above, the adhesive film does not consist of a single layer of an adhesive material. Rather, the one-sided adhesive film 25 is made up of an adhesive layer 60 and a protective layer 62 such as a PC tape. The adhesive tape is given additional stability by the PC tape and the PC tape also has special optical properties which are particularly advantageous in the case of a DVR. As described above, the adhesive film 25 has sections which are punched out in accordance with the size and shape of an upper side of the data carrier to be bonded. With this type of adhesive film, the process station 11 can be omitted since curing of the adhesive film is not necessary.
Die Erfindung wurde zuvor anhand bevorzugter Ausführungsbeispiele der Erfindung beschrieben, ohne jedoch auf die speziellen Ausführungsbeispiele beschränkt zu sein. Der Datenträger kann beispielsweise nach Art einer Diskette innerhalb eines ihn umgebenden Gehäuse angeordnet sein, was die mechanischen Anforderungen an die Beschichtung stark verringert. In diesem Fall könnte die Prozeßstation 11 entfallen, da nach dem Auflaminieren der Klebefolie (Kleberschicht) kein weiterer Prozeßschritt notwendig wäre. Das Aushärten der Kleberschicht kann durch Druck und/oder Zeit und/oder durch eine Bestrahlung, wie beispielsweise mit UV-Licht oder durch eine thermische Behandlung erfolgen. The invention has been described above on the basis of preferred exemplary embodiments of the invention, but without being restricted to the specific exemplary embodiments. The data carrier can be arranged, for example, in the manner of a floppy disk within a housing surrounding it, which greatly reduces the mechanical requirements on the coating. In this case, the process station 11 could be omitted, since no further process step would be necessary after the adhesive film (adhesive layer) had been laminated on. The adhesive layer can be cured by pressure and / or time and / or by irradiation, for example with UV light, or by a thermal treatment.
