Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung der im Oberbegriff des ersten bzw. dritten Anspruchs angegebenen Art.The invention relates to a device in the preamble of the first or third claim specified Art.
Bei der Herstellung von Kunststoff-Ausstattungsteilen für den Kraftfahrzeuginnen raum, beispielsweise Instrumententafeln, Armlehnen etc., wird ein Kunststoff-Träger als Basisteil verwendet, der in einem weiteren Arbeitsgang mit einer Oberflächen haut versehen wird. Gleichzeitig wird eine Schaumschicht zwischen Oberflächen haut und Träger eingespritzt. Hierbei läßt es sich nicht verhindern, daß die Schaum schicht auch auf die Flächen des Trägers gelangt, die an und für sich nicht mit einer Schaumschicht versehen werden sollen, weil sie noch für andere Zwecke benötigt werden. Diese Schaumschicht mußte dann in einem weiteren Arbeitsgang von Hand eventuell mit Hilfe einer geeigneten Einrichtung entfernt werden, wobei zum leichte ren Entfernen vor dem Aufbringen der Schaumschicht ein Trennmittel auf diese Flä chen des Trägers aufgebracht wurde.In the manufacture of plastic fittings for motor vehicles space, for example instrument panels, armrests etc., becomes a plastic carrier used as the base part, which in a further operation with a surface skin is provided. At the same time there is a layer of foam between surfaces Skin and carrier injected. This cannot prevent the foam layer also reaches the surfaces of the carrier, which in and of themselves are not covered by a Foam layer should be provided because it is still needed for other purposes become. This layer of foam then had to be carried out by hand in a further operation possibly removed with the help of a suitable device, whereby for easy Remove a release agent on these surfaces before applying the foam layer Chen the carrier was applied.
Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen und ein Verfah ren und eine Vorrichtung zur Durchführung des Verfahrens bereitzustellen, mit dem die Schaumschicht an den nicht benötigten Flächen des Trägers einfach und schnell entfernt werden kann. The object of the present invention is to remedy this and a procedure Ren and provide an apparatus for performing the method with which the foam layer on the surfaces of the carrier that are not required simply and quickly can be removed.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des ersten bzw. dritten Anspruchs gelöst. Die Erfindung basiert auf der Erkenntnis, daß die überflüssige Schaumschicht an den nicht benötigten Flächen des Trägers sehr leicht entfernt werden kann mit Hilfe eines Flüssigkeitshochdruckstrahles. Mit Hilfe dieses Flüs sigkeitshochdruckstrahles wird der nicht benötigte Schaum abgerissen und zwar ohne daß die Schaumschicht an den benötigten Stellen zerstört wird.This object is achieved by the features of the first and third Claim solved. The invention is based on the knowledge that the superfluous Foam layer on the unnecessary surfaces of the carrier can be removed very easily can be with the help of a high pressure liquid jet. With the help of this river high pressure jet, the foam that is not required is torn off without the foam layer being destroyed at the required points.
Die Arbeitszeit zum Entfernen der nicht benötigten Schaumschicht kann mit dem erfindungsgemäßen Verfahren drastisch verkürzt werden.The working time for removing the unnecessary foam layer can be with the The method according to the invention can be drastically shortened.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens ist es, daß nun kein Trenn mittel mehr aufgetragen werden muß, da der Flüssigkeitshochdruckstrahl in der Lage ist, die Schaumstoffschicht auch ohne die Verwendung eines Trennmittels zu entfernen.Another advantage of the method according to the invention is that there is now no separation medium more must be applied because the liquid high pressure jet in the Is able to close the foam layer without the use of a release agent remove.
Als geeignete Düse hat sich die Schmutzfräserdüse eines Hochdruckreinigers er wiesen. Auch kann die Flüssigkeitshochdruckpumpe Teil eines Hochdruckreinigers sein, der marktüblich ist und mit unbehandeltem Wasser aus dem Wassernetz be trieben werden kann.The dirt cutter nozzle of a high-pressure cleaner has proven to be a suitable nozzle grasslands. The high-pressure liquid pump can also be part of a high-pressure cleaner be that is customary in the market and be with untreated water from the water network can be driven.
Besonders vorteilhaft ist es, daß die Düse von einem Roboter geführt werden kann, so daß die Arbeit nunmehr vollautomatisch ohne Zuhilfenahme eines Werkers durchgeführt werden kann.It is particularly advantageous that the nozzle can be guided by a robot, so that the work is now fully automatic without the help of a worker can be carried out.
Mit der Erfindung ist es somit möglich, punktgenau und vollautomatisch die nicht benötigte Schaumschicht von Trägern zu entfernen, ohne die Schaumschicht oder die Oberflächen haut an anderen Stellen des Trägers zu beschädigen.With the invention, it is therefore possible to pinpoint and not fully automatic to remove the required foam layer from supports without the foam layer or damaging the surface skin on other parts of the wearer.
In der einzigen Figur ist schematisiert ein Ausführungsbeispiel der Erfindung dar gestellt. Mit 1 ist ein Kunststoff-Ausstattungsteil bezeichnet, das aus einem Kunststoff-Träger 2 besteht, der auf seiner Außenseite eine Oberflächenhaut 3 trägt, die mit dem Kunststoff-Träger 2 über eine Schaumschicht 4 verbunden ist.In the single figure, an embodiment of the invention is shown schematically. 1 with a plastic equipment part is referred to, which consists of a plastic carrier 2 , which has on its outside a surface skin 3 , which is connected to the plastic carrier 2 via a foam layer 4 .
In dem Kunststoff-Träger 2 sind Ausnehmungen 5 vorhanden, die zum Befestigen anderer Bauteile dienen.In the plastic carrier 2 there are recesses 5 which are used to fasten other components.
Beim Einführen des Schaumes 4 kann nicht verhindert werden, daß der Schaum 4 durch die Ausnehmungen 5 auf die Rückseite des Kunststoff-Trägers 2 tritt. Der auf den zu reinigenden Flächen 6 des Kunststoff-Trägers 2 sich absetzende Schaum wurde bisher in einem separaten Arbeitsgang von Hand entfernt.When the foam 4 is introduced, it cannot be prevented that the foam 4 passes through the recesses 5 onto the back of the plastic carrier 2 . The foam that settles on the surfaces 6 of the plastic carrier 2 to be cleaned has previously been removed by hand in a separate operation.
Erfindungsgemäß wird dies nun durch einen aus einer Düse 7 austretenden Hoch druckstrahl 8 entfernt. Die Düse 7 ist Teil eines handelsüblichen Hochdruckreinigers. Vorteilhafterweise wird die Schmutzfräserdüse eines Hochdruckreinigers verwendet, bei der der Flüssigkeitsstrahl rotierend aus der Düsenöffnung austritt. Als Flüssigkeit kann unbehandeltes Wasser verwendet werden.According to the invention, this is now removed by a high-pressure jet 8 emerging from a nozzle 7 . The nozzle 7 is part of a commercially available high-pressure cleaner. The dirt-milling nozzle of a high-pressure cleaner is advantageously used, in which the liquid jet emerges rotatingly from the nozzle opening. Untreated water can be used as the liquid.
