Verfahren und Vorrichtung zum Beschichten von Folienmaterial Method and device for coating film material

Lie Erfindung bezieht sich auf ein Verfahren und auf eine Vorrichtung zum Beschichten von Folienmaterial beliebiger Gestalt mit einer spritz- und preßbaren, das Folienmaterial stabilisierenden Masse.The invention relates to a method and an apparatus for coating film material of any desired type Shape with a sprayable and compressible, the film material stabilizing mass.

Derartiges im allgemeinen aus Kunststoff bestehendes Folienmaterial wird heute für viele Anwendungsfälle zur Abdeckung bzw. Verkleidung verwendet. Insbesondere in der Autoindustrie wird dieses Folienmaterial zur Verkleidung der Armaturenbretter, der in den Innenraum hineinragenden Radkasten oder anderer flächen eingesetzt. Die sichtbare Oberfläche des Folienrnaterials ist dabei aus ästhetischen Gesichtspunkten mit dekorativen Wustern versehen, während auf der verdeckten Seite des ein- oder mehrschichtigen Folienmaterials eine stabilisierende Masse angebracht ist, die auch der Geräuschdämmung dienen kann. Da das Folienmaterial im allgemeinen sehr dünn ausgebildet ist, bestehen große Schwierigkeiten, die stabilisierende Masse mit wirtschaftlich vertretbarem Aufwand auf das Folienmaterial aufzubringen, ohne daß dasselbe dabei zerstört wird.Such sheet material generally consisting of plastic is used today for many applications for covering or cladding. Especially in the auto industry this film material is used to clad the dashboards, the wheel arches protruding into the interior or others surfaces used. The visible surface of the film material is provided with decorative clusters from an aesthetic point of view, while on the hidden one Side of the single or multi-layer film material a stabilizing mass is attached, which also the noise insulation can serve. Since the sheet material is made very thin in general, there are great difficulties stabilizing mass with economically justifiable effort to apply to the sheet material without the same is destroyed in the process.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Beschichten von Folienmaterial anzugeben, mit dem bei wirtschaftlicher Fertigung eine zerstörungsfreie Aufbringung der Beschichtungsmasse, unabhängig von der Gestalt des Folienmaterials sichergestellt ist.The invention is based on the object of specifying a method for coating film material with which the more economical Manufacture of a non-destructive application of the coating compound, regardless of the shape of the film material is ensured.

Diese Aufgabe wird mit einem Verfahren der eingangs geschilderten Art gemäß der Erfindung dadurch gelöst, daß dasThis object is achieved with a method of the type described above according to the invention in that the

zunächst ebene, erwärmte Folienmaterial mittels eines Niederhalters an den beweglichen, eine der späteren Gestalt des Folienmaterials angepaßte Oberfläche aufweisenden Formteil einer Spritzgießform angedrückt wird, daß das Folienmaterial danach durch Unterdruck auf die Oberfläche des beweglichen Formteils gezogen wird, daß anschließend bei an den feststehenden Formteil der Spritzgießvorrichtung herangefahrenem beweglichen Formteil, in den zwischen Folienmaterial und feststehendem Formteil verbleibenden Spalt die Masse langsam eingespritzt wird, und daß diese Masse schließlich durch weiteres Zusammenfahren der beiden Formteile in der erforderlichen Dicke ausgepreßt und auf das Folienmaterial verteilt wird.initially flat, heated film material by means of a hold-down device on the movable, one of the later shape of the film material adapted surface having molded part an injection mold is pressed that the film material is then drawn by negative pressure on the surface of the movable mold part, that then at the fixed Molded part of the injection molding device moved up movable molded part, in the between the film material and the stationary Molded part remaining gap the mass is slowly injected, and that this mass finally by further Bringing the two molded parts together is pressed out to the required thickness and distributed on the sheet material.

Ein Vorteil dieses Verfahrens besteht darin, daß das Folienmaterial durch den Einsatz des Unterdrucks in einem Arbeitsgang in die gewünschte Form gebracht und gleichzeitig mit der Masse beschichtet wird. Da die Beschichtung nicht nur durch Spritzen erfolgt, sondern durch ein kombiniertes Spritzen und Pressen, kann die mit niedriger Geschwindigkeit in den Spritzraum eingebrachte Masse das Folienmaterial nicht zerstören. Bei dem abschließenden Auspressen wird die Masse ebenfalls relativ langsam auf dem Folienmaterial verteilt, so daß auch dabei die Gefahr einer Beschädigung nicht besteht. Durch den Einsatz des Niederhalters ist außerdem ein einfacher Aufbau der für die Durchführung des Verfahrens eingesetzten Sprxtzgießvorrxchtung gegeben, da dieser Niederhalter im Zusammenwirken mit dem Folienmaterial die für die Erzeugung des Unterdrucks erforderliche Abdichtung herstellt.An advantage of this method is that the sheet material brought into the desired shape in one operation by using the negative pressure and simultaneously with the Mass is coated. Since the coating is not just done by spraying, but by a combined spraying and pressing, the low speed can be in the The mass introduced into the injection chamber does not destroy the film material. During the final pressing out, the mass is also distributed relatively slowly on the film material, so that there is also no risk of damage. By the use of the hold-down device is also a simple structure of the one used for carrying out the method Sprxtzgießvorrxchtung given, since this hold-down in cooperation with the film material for the generation of the Produces the required vacuum seal.

Das Verfahren nach der Erfindung wird im folgenden anhand der Zeichnungen beispielsweise erläutert.The method according to the invention is explained below with reference to the drawings, for example.

Mit 1 ist der bewegliche Formteil einer Spritzgießvorrichtung bezeichnet, deren feststehender Teil 2 einen beispielsweise ringförmig ausgebildeten Niederhalter 3 trägt, der im Formteil 2 federnd gelagert ist. Über der Spritzgießvorrichtung ist ein Transportband 4 angeordnet, an dem das zu bearbeitende Folienmaterial 5 derart befestigt ist, daß es in dem Zwischenraum zwischen den beiden Formteilen 1 und 2 hängt. Der Aufbau des Folienmaterials ist dabei beliebig, und es kann dementsprechend ein oder mehrschichtig ausgeführt sein. Es wird in zunächst ebenem Zustand in die Spritzgießvorrichtung eingebracht. In beiden Formteilen 1 und 2 sind Bohrungen angebracht, in die zur Kühlung bzw. Beheizung der Formteile ein entsprechendes Medium eingebracht werden kann.1 with the movable mold part of an injection molding device is referred to, the fixed part 2, for example carries ring-shaped hold-down device 3, which is resiliently mounted in the molded part 2. Above the injection molding machine a conveyor belt 4 is arranged on which the film material 5 to be processed is attached in such a way that it is in the space between the two mold parts 1 and 2 depends. The structure of the film material is arbitrary, and it can accordingly be designed in one or more layers. It is initially in a flat state in the injection molding device brought in. In both molded parts 1 and 2 there are holes in which to cool or heat the molded parts an appropriate medium can be introduced.

Der bewegliche Formteil 1 ist so gestaltet, daß seine Oberfläche der herzustellenden Gestalt des beschichteten Folien materials entspricht. Im dargestellten Fall ergibt sich eine konkave Form des Hohlraums 8 des beweglichen Formteils. In der Oberfläche dieses Hohlraums 8 liegen Öffnungen eines Kanals 7» an welchen eine der Einfachheit halber nicht dargestellte Einrichtung zur Erzeugung von Unterdruck angeschlossen ist. Die Oberfläche des feststehenden Formteils 2 ist der Oberfläche des Formteils 1 angepaßt.The movable mold part 1 is designed so that its surface of the shape to be produced of the coated film material is equivalent to. In the case shown, there is a concave shape of the cavity 8 of the movable molded part. In the surface of this cavity 8 are openings of a channel 7 'on which one is not shown for the sake of simplicity Device for generating negative pressure is connected. The surface of the fixed molding 2 is the Surface of the molded part 1 adapted.

Nach dem Einbringen des erwärmten Folienmaterials 5 in die Spritzgießvorrichtung wird der Formteil 1 auf den Formteil 2 zubewegt, bis der Niederhalter 3 das Folienmaterial 5 fest an den Formteil 1 andrückt. Danach wird durch Erzeugung des Unterdrücke das Folienmaterial in den Hohlraum 8 bis zur Anlage an der Oberfläche hineingezogen, so daß sich die aus Fig. J ersichtliche Lage ergibt. Anschließend wird die für die Be-After the heated film material 5 has been introduced into the In the injection molding device, the molded part 1 is moved towards the molded part 2 until the hold-down device 3 firmly attaches the film material 5 the molded part 1 presses. Thereafter, by generating the negative pressure, the film material is in the cavity 8 up to the plant drawn in at the surface so that the position shown in FIG. J results. Then the

schichtung vorgesehene Masse 9 durch die zentrale Bohrung des Formteils 2 in den Spalt 10 zwischen Folienmaterial und Formteil 2 mit geringer Geschwindigkeit und niedrigem Druck eingespritzt, so daß sich entsprechend Fig. 2 zunächst zentral eine Beschichtung größerer Wandstärke ergibt.layering provided mass 9 through the central bore of the molded part 2 into the gap 10 between the film material and the molded part 2 at low speed and low pressure injected, so that, as shown in FIG. 2, there is initially a coating of greater wall thickness in the center.

Nachdem eine ausreichende Menge der Masse 9 eingespritzt ist, wird die Bohrung im Formteil 2 verschlossen und die Masse 9 wird durch ein weiteres Zusammenfahren der Formteile 1 und 2 bis zur Erreichung der gewünschten Wandstärke ausgepreßt, wobei sie sich langsam über die gesamte am Spalt 10 vorhandene Oberfläche des Folienmaterials verteilt.After a sufficient amount of the mass 9 has been injected, the bore in the molded part 2 is closed and the mass 9 is pressed out by moving the molded parts 1 and 2 together further until the desired wall thickness is reached, with it is slowly distributed over the entire surface of the film material present at the gap 10.

Um das Aufziehen des Fölienmaterials 5 auf die Oberfläche des Formteils 1 zu ermöglichen, wird das Folienmaterial vorher erwärmt, was kontinuierlich mittels einer Heizvorrichtung 11 erfolgen kann, an der das Folienmaterial mittels des Transportbandes 4 vorbeigeführt wird. Die Heizvorrichtung kann beispielsweise mit Infrarotstrahlern ausgerüstet sein.In order to pull the film material 5 onto the surface of the To enable molded part 1, the film material is previously heated, which is done continuously by means of a heating device 11 can, on which the film material is passed by means of the conveyor belt 4. The heating device can, for example be equipped with infrared heaters.

Die Oberfläche des Formteils 1 wird zweckmäßig von vornherein gekühlt, indem ein Kühlmedium durch die Bohrungen 6 geleitet wird. Hierdurch wird das Folienmaterial 5 nach der Anlage an der Oberfläche des Formteils 1 sofort gekühlt und auch der Prozeß der festen Haftung zwischen Folienmaterial 5 und Masse wird beschleunigt. Der Formteil 2 wird in seinen Bohrungen 6 mit einem erwärmten bzw. aufgeheizten Medium beaufschlagt, um die Masse 9 fließfähig zu halten.The surface of the molded part 1 is expediently cooled from the outset in that a cooling medium is passed through the bores 6. As a result, the film material 5 is cooled immediately after it has been in contact with the surface of the molded part 1, and the process of firm adhesion between the film material 5 and the mass is also accelerated. The molded part 2 is acted upon in its bores 6 with a heated or heated medium in order to keep the mass 9 flowable.

Um ein nachträgliches Beschneiden des beschichteten Folienmaterials zu vermeiden, kann der den Spritzraum begrenzende Niederhalter 3 auch mit einer Abquetschkante ausgerüstet werden, so daß nach dem Auspressen der Masse 9 und ausreichender Abkühlung das fertige, beschichtete Formteil aus der Spritzgießvorrichtung herausgenommen werden kann, ohne daß noch eine Nacharbeit erforderlich ist.A subsequent trimming of the coated film material To avoid this, the hold-down device 3 delimiting the injection chamber can also be equipped with a pinch-off edge, so that after the mass 9 has been pressed out and has cooled sufficiently, the finished, coated molded part from the injection molding device can be removed without reworking is required.
