Abstract

Film reels are driven be a transmission from a motor connected by an electrical shaft to the drive of the pressing rollers in a plant for coating boards on one side or both with a layer of plastics film e.g. melamine. The value of the control signal is derived by comparison of the actual value and the nominal value of a measurement of the motion of the films running from the reels and through the pressing rollers. The tension on the film is damped by one or more compensating rollers. A further control signal value for the drive is obtained by measuring the sag in the fil, which is transmitted to the control unit. Makes it possible to process brittle melamine films from the reel in a continuously working plant. The film is drawn with the minimum of tension and without jolting. The invention ensures that the variable imbalance, the variable inertia and the variable bearing friction between full and empty reels do not affect the tension on the film.

Description

Einrichtung zum ein- oder beidseitigenFacility for one or both sides

Kaschieren von Platten mit Folien Die Erfindung bezieht sich auf eine Einrichtung zum ei oder beidseitigen Kaschieren von Platten mit Folien, wobei die Folien von Wickel kontinuierlich abgezogen und durch Kaschierwalzen auf die Platten aufgepreßt werden.Laminating panels with Foils The invention relates to a device for laminating sheets on one side or both sides with foils, the foils being continuously withdrawn from the roll and pressed onto the sheets by laminating rollers.

Damit man Folien, insbesondere spröde Melaminfolien, von der Rolle in einer kontinuierlichen Kaschieranlage verarbeiten kann, müssen diese mit geringstem Folienzug und ruckfrei abgewickelt werden.So that foils, especially brittle melamine foils, can be taken off the roll can process in a continuous laminating system, this must be done with the least Film tension and can be handled without jerks.

Bei bekannten Anlagen werden die Folienwickel in Abhängigkeit vom Wickeldurchmesser so gebremst, daß die Folien immer straff gespannt sind. Bedingt durch die lagerreibung der Wickelrolle bzw. des Bremsmoments ergibt dies immer noch einen zu großen Folienzug und damit die Gefahr, daß die Folie einreißt oder sogar durchreißt.In known systems, the film rolls are dependent on The winding diameter is braked so that the foils are always taut. Conditional This still results from the bearing friction of the winding roll or the braking torque too much film tension and thus the risk of the film tearing or even tears through.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, mit der die variable Massenumwucht, die variable Massenträgheit und die variable Lagerreibung zwischen vollem und leerem J?oliernckel nicht auf den Folienzug einwirt.The invention is based on the object of a device of the initially called type to create with which the variable mass imbalance, the variable mass inertia and the variable bearing friction between full and empty J? oliernckel does not arise host the film draw.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß daß die Folienwickel über ein Getriebe von einem ; tor angetrieben werden, der mit dem Antrieb der Kaschierwalzen über eine elektrische Welle verbunden ist, und daß als Regelgröße der Ist- und Sollwertvergleich einer Wegmessung zwischen der von den Folienwickel abgehenden und der durch die Kaschierwalzen durchgehenden Folien dient.This object is achieved according to the invention in that that the film roll via a gearbox from one; tor driven with the Drive of the laminating rollers is connected via an electric shaft, and that as Controlled variable of the actual and setpoint comparison of a distance measurement between the Foil rolls outgoing and the foils passing through the laminating rollers are used.

Damit wird erreicht, daß die Folien immer unter kleinstmöglicher Zugspannung und völlig ruckfrei abgewickelt werden. Um auch einen ruckfreien und weichen Anlauf beim Start der Kaschierlage zu erreichen, besteht eine Weiterbildung der Erfindung darin, daß zwischen den Folienwickel und den Kaschierwalzen Tänzerwalzen eingebaut sind.This ensures that the foils are always subjected to the lowest possible tensile stress and can be handled completely smoothly. To ensure a smooth and smooth run-up To achieve at the start of the liner, there is a further development of the invention in that dancer rollers are installed between the film roll and the lamination rollers are.

Eine vorteilhafte Ausgestaltung besteht ferner darin, daß als weitere Regelgröße für den Antrieb, die Meßwerte einer Folien-Durchhang-Meßvorrichtung in die Steuerung eingegeben werden.An advantageous embodiment is also that as a further Controlled variable for the drive, the measured values of a film sag measuring device in the control can be entered.

In der Zeichnung sind mit 1 die mit den Folien 2 und 3 zu Kaschierenden und zwischen den Kaschierwalzen 6 und 7 hindurchlaufenden Platten 1 bezeichnet, die aus verschiedenen Werkstoffen bestehen können. Vornehmlich werden Spanplatten, Faserpiatten, Sperrholzplatten, Asbestzementplatten, Mineralfo platten und Gipskarton-Platten in der Industrie it Folien beschichtet. ic Folien 2 und 3 werden gemäß der Erfindung von Folienwic:el 4 und 5 nicht nur von den Kaschierwalzen 6 und 7 gezogen, sondern erhalten durch den Weg-Synchron gesteuerten Antrieb der Folienwickel 4 und 5 auch einen Schub, so daß die Zugkraft auf die Folien 2 und 3 nie zu groß wird.In the drawing, 1 denotes the plates 1 to be laminated with the foils 2 and 3 and running between the laminating rollers 6 and 7, which plates can consist of different materials. Mainly chipboard, fiberboard, plywood, asbestos-cement board, mineral foam panels and plasterboard in the industry coated with foils. ic foils 2 and 3 are according to the invention of Folienwic: el 4 and 5 not only pulled by the lamination rollers 6 and 7, but also receive a thrust through the synchronously controlled drive of the foil reels 4 and 5, so that the tensile force on the Slides 2 and 3 never get too big.
