Description
Verfahren und Einrichtung zum Dekorieren von flachen Kunststoffplatten Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Dekorieren von mittels einer Breitschlitz- bzw. Profildüse extrudierten flachen Kunststoffplatten, die gegebenenfalls an einer Flachseite sich in einer Richtung erstreckende Versteifungsrippen aufweisen oder die hohl sind und deren Hohl -raum durch sich in einer Richtung erstreckende, zwischen dem oberen und unteren Plattenteil angeordnete Stege in einzelne Zellen unterteilt ist. Method and device for decorating flat plastic sheets The invention relates to a method and a device for decorating means a slot or profile nozzle extruded flat plastic plates, the if necessary stiffening ribs extending in one direction on a flat side have or which are hollow and their hollow space by extending in one direction, between the upper and lower plate part arranged webs in individual cells is divided.
Flache Kunststoffplatten finden yielseitig Verwendung. Anwendungsgebiete finden sich zur Schalldämmung, zum Ausfüllen von Hohlräumen. Insbesondere werden jedoch solche Platten. von der Verpackungsindustrie zur Herstellung von schachtelartigen Verpackungsbehältern benötigt.Flat plastic plates are used on all sides. application areas can be found for sound insulation, for filling cavities. In particular, be however, such plates. from the packaging industry to the manufacture of box-like Packaging containers required.
Die verhältnismässig dünnen, flachen Kunststoffplatten haben, wenn sie die Breitschlitz- bzw. Profildüse verlassen, ein mattfarbenes Aussehen und müssen in vielen Fällen,bevor sie zu Behältern verarbeitet werden, zumindest an ihrer später an der Bebälteraussenseite liegenden Flachseite dekoriert werden, um den Behältern ein gefälliges Aussehen zu geben bzw.The relatively thin, flat plastic plates have if if they leave the slot or profile nozzle, they have a matt-colored appearance and must in many cases before they are made into containers, at least at their later on the flat side lying on the outside of the container can be decorated around the containers to give a pleasing appearance or
den Behälterinhalt anzuzeigen. Es ist naheliegend, dass das Dekorieren der Kunststoffplatten sehr viel Zeit erfordert und sich demgemäss die Herstellung der Behälter entsprechend ver- -teuert.display the contents of the container. It goes without saying that decorating the plastic sheets requires a lot of time and accordingly the production the container is priced accordingly.
Die Erfindung befasst sich nun mit einem Verfahren und mit einer Einrichtung, mit deren Hilfe das Dekorieren von flachen Kunststoffplatten zeit- und kostensparend durchführbar ist.The invention is now concerned with a method and with a device, with the help of which the decoration of flat plastic sheets saves time and money is feasible.
Das erfindungsgemässe Verfahren zeichnet sich dadurch aus, dass auf mindestens einen Teil der Fläche mindestens einer Plattenseite eine auf ihrer einen Seite mit Dekorationsmotiven bedruckte, transparente Kunststoffolie fest aufgebracht wird.The method according to the invention is characterized in that at least part of the surface of at least one side of the plate one on its own Side with printed, transparent plastic film firmly attached will.
Bei diesem Verfahren ist die auf den Kunststoffplatten#vorzusehende Dekorierung bereits auf einem Träger aufgebracht, der sich seinerseits verhältnismassig einfach auf die entsprechende Plattenfläche aufziehen lässt. Die Dekorierung wird damit als Ganzes auf die Kunststoffplatten übertragen und nicht erst auf diesen, beispielsweise im Siebfarbdruck, hergestellt. Darüber hinaus lässt sich durch das Aufbringen der Kunststofffolie eine hochglänzende Oberfläche der Kunststoffplatten erzeugen. Die Erfindung bietet dabei die Möglichkeit eines wirksamen Abriebschutzes des Dekors, sofern die bedruckte Kunststoffolie derart auf die Kunststoffplatten aufgebracht wird, dass die bedruckte Folienseite an der zu dekorierenden Plattenfläche anliegt.With this method, the one on the plastic plates # is to be provided Decoration already applied to a carrier, which in turn is relatively can simply be pulled onto the corresponding plate surface. The decoration will thus transferred as a whole to the plastic plates and not only on them, for example in screen color printing. In addition, the Applying the plastic film a high-gloss surface of the plastic plates produce. The invention offers the possibility of effective abrasion protection of the decor, provided the printed plastic film is applied to the plastic panels is applied that the printed film side on the panel surface to be decorated is present.
Die mit Dekorationsmotiven bedruckte Folie kann auch auf die gesamte Fläche der zu dekorierenden Plattenseite aufgebracht werden, wobei sich die Möglichkeit ergibt, die Dekorationsmotive nur entlang einer oder mehrerer Bahnen vorzusehen, so dass zwar die gesamte Plattenfläche eine hochglänzende Oberfläche aufweist, jedoch nur ein Teil hiervon dekoriert ist.The foil printed with decorative motifs can also be applied to the entire Surface of the board side to be decorated, with the possibility of results in providing the decorative motifs only along one or more tracks, so that although the entire plate surface has a high-gloss surface, however only part of it is decorated.
Die Kunststoffolie kann nach Fertigstellung der Kunststoffplatten auf diese aufgebracht werden. In diesem Falle lässt sich das erfindungsgemässe Verfahren besonders vorteilhaft durchführen, wenn die Kunststoffolie,insbesondere auf ihrer bedruckte ten Seite, mit einem unter Wärmeeinwirkung erweichenden Haftlack beschichtet und die Kunststoffolie beim Zusammenführen mit einer fertigen Kunststoffplatte gegebenenfalls zusammen mit der letzteren erwärmt wird, wodurch eine blasenfreie und schnelle Verbindung von Kunststoffolie und Kunststoffplatte sichergestellt ist. Das Verfahren lässt sich jedoch auch so gestalten, dass unmittelbar bei der Herstellung der Kunststoffplatten auch die Dekorierung auf diese aufgebracht wird, indem unmittelbar nach Austritt der Kunststoffplatten aus der Breitschlitz- bzw. Profildüse die Kunststoffolie auf die Kunststoffplatten aufgebracht wird, wobei dann unter Ausnutzung der Schmelzwärme eine Verschweissung der Folie mit de) Oberfläche der Kunststoffplatten erfolgt.The plastic film can after completion of the plastic plates be applied to this. In this case, the method according to the invention can be used perform particularly advantageous when the plastic film, especially on its printed th side, coated with a heat-softening adhesive varnish and the plastic film when it is brought together with a finished plastic plate, if applicable along with the latter is heated, creating a bubble-free and quick connection is ensured by plastic film and plastic plate. The procedure leaves however, they can also be designed in such a way that directly during the production of the plastic sheets also the decoration is applied to this by immediately after exit the plastic sheets from the slot or profile nozzle on the plastic film the plastic sheets is applied, then taking advantage of the heat of fusion the film is welded to the surface of the plastic plates.
Bei der erfindungsgemässen Dekorierung von Kunststoffplatten lassen sich weiterhin noch dadurch bestimmte Effekte erzielen, dass mindestens zonenweise, vorzugsweise in die gesamte zu de-# korierende Plattenfläche der Kunststoffplatten Vertiefungen eingebracht werden, in welche die dekorierte Kunststoffolie bei Aufbringen auf diese-Plattenfläche mindestens zum Teil eingezogen wird. Eine besonders ansprechendes Dekorationsbild lässt sich hierbei erzielen, wenn die Umfangsform der Vertiefungen dem Umriss der Dekorationsmotive entspricht und wenn beim Zusammenführen von Kunststoffolie und Kunststoffplatten die die Dekoratiossmotive tragenden Folienteile in die Vertiefungen eingezogen werden. Es entsteht so ein farbig angelegtes, plastisches Dekorationsbild, wobei die einzelnen Dekorationsmotive und Vertiefungen klein und/oder grossflächig ausgelegt sein können.In the case of the decoration of plastic panels according to the invention certain effects can still be achieved by at least zone-wise, preferably in the entire plate surface of the plastic plates to be decorated Wells are introduced into which the decorated plastic film when applied is drawn in at least in part on this plate surface. A particularly appealing one Decoration picture leaves can be achieved here if the circumferential shape the depressions correspond to the outline of the decorative motifs and if when they are brought together of plastic film and plastic plates, the film parts carrying the decorative motifs drawn into the indentations. The result is a colored, three-dimensional Decorative image, with the individual decorative motifs and depressions small and / or can be designed over a large area.
Das erfindungsgemässe Verfahren ermöglicht es ohne weiteres, Kunststoffplatten auch auf beiden Flachseiten zu dekorieren, bzw. durch Aufziehen einer Kunststoffolie eine hochglänzende Oberfläche zu #erleihen; in diesem Falle wird man mindestens die Kunststoffolie mit Dekorationsmotiven versehen, die später bei der Herstellung der Verpackungsbehälter an der Aussenseite derselben liegen wird.The method according to the invention makes it possible, without further ado, to produce plastic sheets can also be decorated on both flat sides, or by pulling on a plastic film #lend a high-gloss surface; in this case one will at least the plastic film is provided with decorative motifs, which are later used during manufacture the packaging container will be on the outside of the same.
Die Durchführung des Verfahrens ist nicht auf eine bestimmte Art von Kunststoffplatten beschränkt.Die Kunststoffplatten können beispielsweise massiv sein.The implementation of the procedure is not limited to a specific type of Plastic panels limited. For example, the plastic panels can be solid be.
Sollen Kunststoffplatten dekoriert werden, die im Innern durch Rippen gebildete Zellen aufweisen und die nach dem Extrudieren und unter der Wirkung eines Vacuums in einer Kalibriereinrichtung kalibriert werden, so wird vorgeschlagen, die Kunststofffolie unmittelbar Vor der Vacuum-Kalibrierung der Kunststoffplatten auf diese aufzubringen.Shall be decorated plastic sheets, the inside by ribs have formed cells and which after extrusion and under the action of a Vacuums are calibrated in a calibration device, it is proposed that the plastic film immediately before the vacuum calibration of the plastic plates to apply on this.
Es i-st aber auch möglich, die Kunststoffolie innerhalb der Kalibriereinrichtun& mit den Kunststoffplatten in -Ver6 zu bringen.However, it is also possible to use the plastic film within the calibration device. to bring with the plastic plates in -Ver6.
Die erfindungsgemässe Einrichtung zur Durchführung des Verfahrens weist zweckmässigerweise ausser einer an einem Extruder angeschlossenen Breitschlitz- bzw.
