Die einzige Zeichnungsfigur zeigt eine Prinzipskizze der erfindungsgemäßen Anlage zur Herstellung von faserverstärkten Kunststoffteilen, insbesondere für Kraftfahrzeuge.The only drawing figure shows a schematic diagram of the system according to the invention for the production of fiber-reinforced plastic parts, in particular for motor vehicles.
Nähere Einzelheiten dieser Anlage werden in dem zuvor erwähnten Dokument FR-A-2 734 199 beschrieben.Further details of this system are described in the previously mentioned document FR-A-2 734 199.
Generell umfaßt diese Anlage eine Maschine 1 zur kontinuierlichen Herstellung einer Paste aus einem Gemisch aus faserverstärktem thermoplastischen Material. Diese Maschine weist beispielsweise einen thermisch geregelten Extruder oder Plastifizierer 2 auf, der einem ersten Einlaß 3 das thermoplastische Material und an einem zweiten Einlaß 5 die Verstärkungsfasem 6 aufnimmt.In general, this system comprises a machine 1 for the continuous production of a paste from a mixture of fiber-reinforced thermoplastic material. This machine has, for example, a thermally controlled extruder or plasticizer 2, which receives the thermoplastic material at a first inlet 3 and the reinforcing fibers 6 at a second inlet 5.
Diese Maschine gestattet es somit, aus dem thermoplastischen Material einerseits und den Verstärkungsfasern andererseits kontinuierlich eine Paste aus einem Gemisch aus dem thermoplastischen Material und den Verstärkungsfasern herzustellen.This machine therefore makes it possible to continuously produce a paste made from a mixture of the thermoplastic material and the reinforcing fibers, on the one hand, and the reinforcing fibers, on the other.
Diese Paste tritt dann beispielsweise aus einer Düse 7 der Maschine 1 aus und gelangt in der Form eines Stranges in eine Speichereinrichtung 8 zum vorübergehenden Sammeln und Speichern der Paste.This paste then exits, for example, from a nozzle 7 of the machine 1 and enters a storage device 8 in the form of a strand for temporary collection and storage of the paste.
Ein Ausführungsbeispiel für eine solche Speichereinrichtung wird ebenfalls in dem vorgenannten Dokument beschrieben.An embodiment of such a storage device is also described in the aforementioned document.
Der Auslaß der Speichereinrichtung 8 weist einen Verschluß 9 auf, der für das Ankuppeln einer Entnahmeeinrichtung 10 ausgebildet ist, mit der die Paste aus der Speichereinrichtung entnommen und in eine Form zur Herstellung des Bauteils überführt wird.The outlet of the storage device 8 has a closure 9 which is designed for the coupling of a removal device 10 with which the paste is removed from the storage device and transferred into a mold for producing the component.
Wie in dem vorgenannten Dokument beschrieben wird, weist die Entnahmeeinrichtung 10 beispielsweise eine thermisch geregelte Einrichtung in der Form ei-As described in the aforementioned document, the removal device 10 comprises, for example, a thermally controlled device in the form of a

ner Spritze 11 auf, die durch eine Handhabungseinrichtung 12 gehalten ist und mit Hilfe dieser Handhabungseinrichtung in eine Ladeposition bewegt werden kann, in der eine Lade/Entladeöffnung 13 der Spritze 11 dem Auslaß der Speichereinrichtung 8 zugewandt ist, so daJ3 Paste aus der Speichereinrichtung in die Spritze überführt werden kann. Aus dieser Ladeposition ist die Spritze in eine Ausgabeposition überführbar.a syringe 11 which is held by a handling device 12 and can be moved with the aid of this handling device into a loading position in which a loading/unloading opening 13 of the syringe 11 faces the outlet of the storage device 8, so that paste can be transferred from the storage device into the syringe. From this loading position, the syringe can be moved into a dispensing position.
In der Ausgabeposition ist die Spritze 11 dazu ausgebildet, die Paste in eine Aufnahmeeinrichtung 14 abzugeben, die einer Form 15 zur Herstellung des Bauteils zugeordnet ist und dazu ausgebildet ist, die Paste in die Form einzugeben.In the dispensing position, the syringe 11 is designed to dispense the paste into a receiving device 14, which is assigned to a mold 15 for producing the component and is designed to introduce the paste into the mold.
Die Aufnahmeeinrichtung 14 hat beispielsweise die Form einer Injektionspresse mit einem Zylinder 16 zur Aufnahme und zum Injizieren von Paste. Der Zylinder 15 weist eine Ladeöffnung 17 auf, durch die die aus der Spritze 11 abgegebene Paste in den Zylinder 16 gelangt. Diese Ladeöffnung 17 ist beispielsweise mit einer Führungseinrichtung für die Paste verbunden, die beispielsweise durch einen Trichter 18 gebildet wird.The receiving device 14 has, for example, the form of an injection press with a cylinder 16 for receiving and injecting paste. The cylinder 15 has a loading opening 17 through which the paste dispensed from the syringe 11 enters the cylinder 16. This loading opening 17 is, for example, connected to a guide device for the paste, which is formed, for example, by a funnel 18.
Der Zylinder 16 hat außerdem eine Abgabeöffnung 19, die dazu ausgebildet ist, die Paste beispielsweise durch eine in der Form 15 ausgebildete Leitung 20 in den Formhohlraum zu injizieren.The cylinder 16 also has a discharge opening 19 which is designed to inject the paste into the mold cavity, for example through a line 20 formed in the mold 15.
Zu diesem Zweck ist ein Kolben 21 beispielsweise in dem Zylinder 16 angeordnet und so verschiebbar, daß beispielsweise eine bestimmte Menge an Paste in die Form injiziert wird. Die Bewegung des Kolbens 21 wird durch eine Steuereinrichtung 22 gesteuert, die irgendwelche geeigneten Stellglieder aufweist.For this purpose, a piston 21 is arranged, for example, in the cylinder 16 and is displaceable so that, for example, a certain amount of paste is injected into the mold. The movement of the piston 21 is controlled by a control device 22 which has any suitable actuators.
Es versteht sich, daß verschiedene Ausführungsformen der Aufnahmeeinrichtung 14 sowie der Form 15 und ihrer Leitung 20 vorgesehen sein können, beispielsweise um eine Injektion der Paste an der Stelle der Teilungsfläche der Form oder eine Mehrpunkt-Einspritzung und dergleichen zu erreichen.It is understood that different embodiments of the receiving device 14 as well as the mold 15 and its line 20 can be provided, for example to achieve an injection of the paste at the location of the parting surface of the mold or a multi-point injection and the like.
Die Zufuhr der Paste in die Form erfolgt mit Hilfe der Aufnahmeeinrichtung 14, so daß die Spritze 11 nicht mit dieser Aufgabe belastet wird. Folglich kann der Takt beschleunigt werden, in dem die Kunststoffteile hergestellt werden, da die Handhabungseinrichtung 12 die Spritze schon während der Zeit wieder in die Ladeposition bringen kann, während der die Paste in die Form injiziert wird, daThe paste is fed into the mold using the receiving device 14, so that the syringe 11 is not burdened with this task. Consequently, the cycle at which the plastic parts are produced can be accelerated, since the handling device 12 can bring the syringe back into the loading position during the time during which the paste is injected into the mold, since
