Description

Die Erfindung bezieht sich auf eine Vorrichiung /um Aufbringen einer transparenten, eine Klebstoffschicht tragenden Schutzfolie auf ein blattförmiges Substrat, mit einem ersten Walzenpaar /um Transportieren des Substrates zusammen mit der Schutzfolie, mit einem zwei Walzen aufweisenden /weiten Walzenpaar zum Zusammenpressen des Substrates und der Schutzfolie und mit einer Heizeinrichtung zum Erwärmen der Klebstoffschichl der Schutzfolie vor dem Zusammenpressen mit dem Substrat.The invention relates to a device Applying a transparent protective film carrying an adhesive layer to a sheet-like substrate, with a first pair of rollers / to transport the substrate together with the protective film, with a two rollers / wide roller pair for pressing the substrate and the protective film together and with a heating device for heating the adhesive layer of the protective film before being pressed together with the substrate.

Bei einer aus der USPS 3143 454 bekannten Vorrichtung wird ein blattförmiges Substrat auf beiden Seiten mit einer transparenten Schutzfolie beschichtet, wobei die jeweils den Oberflächen des Substrates zugewandte Oberfläche der Schutzfolie mit einem Klebstoff beschichtet ist, der durch Anwendung Voh Wärme eCWeichbaf ist* Durch Anwendung von Druck und Wärme werden daher Klebstoffschichten zwischen dem Substrat und den Schutzfolien erweicht und eine klebende Verbindung hergestellt. Die Vorrichtung hat zwei Vorratsrollen für die Sehutzfölien, Die Schutzfolie gelangt jeweils von ihrer Vorratsrolle über eine Spannrolle an ein Walzenpaar, in dessen Förderschlitz das zu beschichtende Substrat eingegeben wird. Da über den Unifang der Walzen des Walzenpaares jeweils dieIn one known from USPS 3,143,454 Device is a sheet-shaped substrate coated on both sides with a transparent protective film, wherein each of the surfaces of the substrate facing surface of the protective film with a Adhesive is coated, which is eCWeichbaf by applying heat * By applying pressure and heat, adhesive layers between the substrate and the protective films are therefore softened and a adhesive connection established. The device has two supply rolls for the protective film, the protective film comes from its supply roll via a tensioning roller to a pair of rollers in its conveyor slot the substrate to be coated is entered. Since over the unifang of the rollers of the roller pair each the

Schutzfolien laufen, deren Außenseite mit einem Klebstoff, z. B. Polyäthylen, beschichtet ist, erhält das in den Schlitz des Walzenpaars eingeführte Substrat sowohl an seiner Ober- als auch an seiner Unterseite die mit Klebstoff beschichtete Schutzfolie. Längs desProtective films run, the outside of which is coated with an adhesive, e.g. B. polyethylene, is coated, the in the substrate introduced into the slot of the pair of rollers on both its upper and lower sides protective film coated with adhesive. Along the

ίο Umfanges der beiden Walzen und vor dem Env ichen des Förderschlitzes zwischen dem Walzenpaar sind jeweils Heizeinrichtungen vorgesehen, die die Klebstoffbeschichtung auf den Schutzfolien mit Wärme beaufschlagen. Der Klebstoff wird daher erweicht undίο the circumference of the two rollers and in front of the Env ichen of the conveyor slot between the pair of rollers, heating devices are provided in each case, which apply the adhesive coating apply heat to the protective film. The adhesive is therefore softened and

is erreicht die gewünschte KlebfähigkeiL Da andererseits oie eigentliche Schutzfolie, die die Klebstoffschicht tragt, offenbar unmittelbar auf der Mantelfläche der beiden Walzen aufliegt, wird diese keiner nennenswerten Erwärmung unterzogen.On the other hand, it achieves the desired adhesive strength o the actual protective film that carries the adhesive layer, apparently directly on the outer surface of the when both rollers are in contact, it is not subjected to any appreciable heating.

Aufgabe der Erfindung ist es. eine Vorrichtung der eingangs genannten Art so weiterzubilden, daß bei geringem Energieverbrauch zur Erwärmung der Schutzfolie diese in kürzester Zeit auf die eine ausreichende Klebfähigkeit sicherstellende Temperatur zu erwärmen ist.It is the object of the invention. to develop a device of the type mentioned so that at low energy consumption to heat the protective film to the one in the shortest possible time The temperature must be heated to ensure sufficient adhesion.

Bei einer Vorrichtung der genannten Art ist diese Aufgabe gemäß der Erfindung dadurch gelöst, daß die Heizeinrichtung und die der Schutzfolie zugeordnete Wal/e des /weiten Walzenpaares in einem thermischIn a device of the type mentioned, this object is achieved according to the invention in that the Heating device and the roller (s) of the wide roller pair assigned to the protective film in one thermal

jo isolierien Kasten angeordnet sind, der mit einem mittels einer Antriebseinrichtung verschicDbaren Deckel vor dem Zusammenpressen des Substrates und der Schutzfolie offenbar und danach verschließbar ist.jo isolierien box are arranged with a means a drive device in front of a cover that can be shipped the pressing of the substrate and the protective film is evident and then closable.

Mit Hilfe der neuen Vorrichtung ist es auch bei einem relativ geringen Energieverbrauch möglich, eine thermoplastische Schutzfolie in kürzester Zeit, nämlich beim Hindurchgang durch den Förderschlitz des Wal/enpaares so stark zu erwarmen, daß es eine seine hohe Klebefähigkeit sicherstellende, relativ hohe Temperatur erreicht. Durch das Einschließen der die Wärme übertragenden ersten Wal/e in eii.em thermisch isolierten Kasten wird dabei sichergestellt, daß die erste Wal/e innerhalb des geschlossenen Kastens in ihrer Bereitschafisstellung sehr intensiv von der sich ebenfalls im Kasten befindenden Heizeinrichtung aufgehei/t wird und sie jeweils di'-se an sie übertragene Warme annähernd ohne Abstrahlungsverluste speichert, bis sie bei geöffnetem Kasten in ihre Betriebsstellung gelangt und diese Wärme an die transparente Schutzfolie abgibt Die neue Vorrichtung si hafft daher in relativ einfacher Weise die wichtige Voraussetzung, daß innerhalb kürzester Zeit in wirtschaftlich vertretbarer Weise eine große Wärmemenge an eine als Über/ugsmat«.nal benutzte transparente Schutzfolie abgegeben wird, damit dieses thermoplastische Material eine ausreichend hohe Temperatur erreicht, um die jeweils gewünschte klebende Wirkung in dem erforderlichen Ausmaß auszuüben.With the help of the new device it is possible, even with relatively little energy consumption, to heat a thermoplastic protective film in a very short time, namely when passing through the conveying slot of the pair of whales, so that it reaches a relatively high temperature ensuring its high adhesive properties. By enclosing the heat-transferring first whale / s in a thermally insulated box, it is ensured that the first whale / s inside the closed box in its ready position is heated very intensively by the heating device also located in the box respectively di'-se to them transmitted Warm approximately stores without radiation losses until it gets opened box into its operating position, and this heat to the transparent protective film to write the new Before r ichtung si Hafft therefore important requirement in a relatively simple manner that, within A large amount of heat is released to a transparent protective film used as an overlay in an economically justifiable manner in the shortest possible time, so that this thermoplastic material reaches a sufficiently high temperature to exert the adhesive effect desired in each case to the required extent.

Der Hebel 26 ist um eine Welle 28 drehbar und weist einen in seinem einen Arm angeordneten Schlitz 26a auf. in dem der Mitnahmezapfen 25 gleiten kann. Ein ähnlicher Schlitz 26b ist in dem anderen Arm des Hebels 26 angeordnet und ein an der Exzenterscheibe 18 befestigter Zapfen 30 gleit.'l in dem Schlitz 26ö. Die txzenterscheibe 18 ist an einer Antriebswelle 17. die mittels einer rrcht dargestellten Federkupplung gedreht werden kann, befestigt. Wenn die Heizeinrichtung 22 klein ist kann die Walze 11 mittels einer nicht dargestellten Haspelwalze langsam in die Wartestellung gedreht werden, um ihre gesamte Oberfläche zu erhitzen. Der Kasten 12 besteht aus rostfreiem Stahl und ist mit Asbest ausgekleidet.A curved part 23a of the cover 23 has a driver pin 25 attached thereto. The lever 26 is rotatable about a shaft 28 and has a slot 26a arranged in its one arm. in which the driving pin 25 can slide. A similar slot 26b is arranged in the other arm of the lever 26 and a pin 30 fastened to the eccentric disk 18 slides in the slot 26ö. The eccentric disk 18 is attached to a drive shaft 17. which can be rotated by means of a spring clutch shown in the right.

Beim Betrieb wird die als Substrat 20 dienende Kennkarte durch eine Führungseinrichtung 32 in Richtung auf die Walzen 10 und 11 geführt. Wenn das Substrat 20 eine vorsynchronisierte Position erreicht, wird ein nicht dargestellter Schalter geschlossen, welcher die Aufnahmespule 6 und die Walzen 4 und 5 dreht, so daß sich die Schutzfolie 1 durch die Vorrichtung bewegt. Gleichzeitig wird die Antriebswelle 17 um eine halbe Umdrehung im Uhrzeigersinne gedreht Die Oberfläche der Exzenterscheibe 18 bewegt dadurch die Achse 16 nach links, so daß der Winkelhebel 13 im Uhrzeigersinne gedreht wird und die Walze 11 wird in Aufwärtsrichtung in die Betriebsposition (F i g. 2) bewegt, in der sie aus dem Kasten 12 herausragt und der Walze 10 benachbart ist GIe* '..zeitig wird der Hebe! 26 ebenfalls im Uhrzeigersinne ^v-'d^eht und der Deckel 23 wird nach rechts in die offene Position (Fig.2) bewegt. Das Substrat 20 wird dann im Vorderseitenkontakt mit der Schutzfolie 1 zwischen die Walzen in und 11 eingeführt, die Wärme und Druck darauf ausüben, um die Klebeschicht der Schutzfolie mit dem Substrat 20 zu verbinden. Das Substrat 20 mit der Schutzfolie 1 läuft dann zwischen den Walzen 5 und 8 hindurch und wird auf einen Aufnr hmetisch 34 ausgeführt. An diesem Punkte wird ein anderer, nicht dargestellter Schalter betätigt, um den Transport der Schutzfolie 1 zu stoppen und zu bewirken, daß die Antriebswelle 17 anschließend im Gegenuhrzeigersinne gedreht wird. Dies führt dazu, daß der Winkelhebel 13 und der Hebel 2h sich im Gegenuhrzeigersinne drehen, wodurch die Walze 10 in die Wartestellung gesenkt wird und wodurch der Deckel 23 geschlossen wird, um einen Wärmeverlust aus dem Kasten 12 zu verhindern.During operation, the identification card serving as substrate 20 is guided by a guide device 32 in the direction of rollers 10 and 11. When the substrate 20 reaches a pre-synchronized position, a switch (not shown) is closed, which rotates the take-up reel 6 and the rollers 4 and 5, so that the protective film 1 moves through the device. At the same time, the drive shaft 17 is rotated by half a turn in the clockwise direction.The surface of the eccentric disk 18 thereby moves the axis 16 to the left, so that the angle lever 13 is rotated clockwise and the roller 11 is in the upward direction into the operating position (Fig. 2 ) moved, in which it protrudes from the box 12 and the roller 10 is adjacent GIe * '.. at the same time the lift! 26 also in a clockwise direction and the cover 23 is moved to the right into the open position (FIG. 2). The substrate 20 is then introduced in front-side contact with the protective film 1 between the rollers in FIGS. 11 and 11, which apply heat and pressure to bond the adhesive layer of the protective film to the substrate 20. The substrate 20 with the protective film 1 then runs between the rollers 5 and 8 and is carried out on a take-up table 34. At this point, another switch, not shown, is actuated to stop the transport of the protective film 1 and to cause the drive shaft 17 to then be rotated counterclockwise. This causes the bell crank 13 and the lever 2h to rotate counterclockwise, lowering the roller 10 to the waiting position and closing the lid 23 to prevent heat loss from the box 12.
