Abstract

In order to obtain a higher laying performance in the production of carbon fibre non-woven fabrics or similar synthetic resin-impregnated materials in web form, a number of individually activatable laying heads is disposed in such a manner that a plurality of webs can be laid out adjacently at the same time. The start of laying and the end of laying of each individual web are determined by the control signals so that flat forms of any desired type can be produced in a material-saving manner.

Description

BESCHREIBUNG DESCRIPTION

MEHRBAND - LEGEMASCHINE Die Erfindung betrifft eine Maschine zum Legen von mehreren mit Kunststoff vorimprägnierten Kohlefaserbändern (im folgenden CFK- Bänder genannt) oder ähnlichen Werkstoffen in Bandform auf eine ebene Unterlage, dadurch gekennzeichnet, daß durch eine Mehrzahl, in zwei Reihen und zueinander versetzt angeordnet, über Signale einzeln ansteuerbarer Bandabroll- und Schneidevorrichtungen jede beliebige Flächenform in materialsparender Weise belegt werden kann. Die etwas klebrige CFK- Bänder werden parallel und nahezu spaltfrei auf eine Kunststoffolie aufgebracht, welche die Funktion eines Transportträgers übernimmt.MULTI-BELT LAYING MACHINE The invention relates to a machine for laying of several carbon fiber tapes pre-impregnated with plastic (hereinafter CFRP Called tapes) or similar materials in tape form on a flat surface, characterized in that by a plurality, in two rows and offset from one another arranged, individually controllable tape unwinding and cutting devices via signals any surface shape can be covered in a material-saving manner. The something sticky CFRP tapes are parallel and almost gap-free on a plastic film applied, which takes on the function of a transport carrier.

Die einzelnen CFK- Lagen werden anschließend in einer ganz bestimmten Reihenfolge, Lagenzahl und Lagenrichtung übereinandergelegt und unter Druck und Temperatur ausgehärtet. Auf diese Weise werden Werkstücke aus diesem leichten und hochfestem Verbundwerkstoff hergestellt.The individual CFRP layers are then in a very specific Order, number of layers and direction of layers superimposed and under pressure and Temperature cured. In this way, workpieces are made from this lightweight and made of high-strength composite material.

Bekannt sind Legemaschinen, welche mit nur einem, meist NC-gesteuerten Legekopf (beinhaltet Bandabroll- und Schneidevorrichtung) ebene oder gekrümmte Flächen mit CFK- Bändern belegen, wobei nacheinander ein Band neben das andere auf die Unterlage mittels einer Andrückrolle aufgebracht wird.Spreading machines are known which have only one, mostly NC-controlled Laying head (includes tape unwinding and cutting device) flat or curved surfaces Cover with CFRP tapes, one tape after the other on the base is applied by means of a pressure roller.

Für besondere Fälle sind Legeköpfe in Entwicklung, welche NC- gesteuert mit Einzelfaden- oder Schmalbandablage arbeiten. Auch hier wird durch das Aufbringen eines Fadens neben dem andern die gewünschte Fläche mit CFK- Material belegt.For special cases, laying heads are under development, which are NC-controlled work with single-thread or narrow tape filing. Again, by applying one thread next to the other covers the desired area with CFRP material.

Bei geringer Verarbeitung werden die Bänder auch manuell auf die vorgegebene Fläche aufgelegt und mit Handrolle angedrückt, wobei der Arbeitsablauf dem der oben erwähnten Maschine entspricht.If there is little processing, the tapes are also manually set to the specified Surface and pressed down with hand roller, being the workflow corresponds to that of the machine mentioned above.

Alle bekannten Legemaschinen arbeiten sehr materialsparend, zeigen jedoch gemessen an ihrem Aufwand eine geringe legeleistung, da das Auslegen der Bänder nacheinander mit einem Legekopf sehr zeitintensiv ist, und der NC- gesteuerte, bewegliche Legekopf mit seiner Masse und den an den Umsteuerpunkten entstehenden Massenkräften einer Erhöhung der Legegeschwindigkeit Grenzen setzt.All known planting machines work very economically, show However, compared to their effort, a low laying performance, as the laying out of the Tapes one after the other with a laying head is very time-consuming, and the NC-controlled, movable laying head with its mass and the resulting at the reversing points Mass forces of an increase in the laying speed sets limits.

Der Erfindung liegt die Aufgabe zugrunde, die Legeleistung bei gleichbleibendem Materialspareffekt durch Verringerung der bewegten Massen zu erhöhen.The invention is based on the object of keeping the laying performance constant To increase the material saving effect by reducing the moving masses.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mehrere in bestimmter Anordnung installierte, jedoch schnellauswechselbare Legeköpfe gleichzeitig die einzelnen Bänder nebeneinander auf eine mit gleichförmiger Geschwindigkeit bewegte Folienunterlage legen. Die bewegten Massen sind gering. Durch die Einzelansteuerung bleibt der Materialeinspareffekt erhalten.This object is achieved according to the invention in that several in installed in a certain arrangement, but quickly replaceable laying heads at the same time moving the individual belts side by side on one at a constant speed Place a foil underlay. The moving masses are low. Through the individual control the material saving effect is retained.

Das Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden beschrieben. FIG.1 zeigt die Draufsicht der Maschine, aus der die zwei hintereinander und versetzt angeordneten Legekopfreihen zu erkennen sind.The embodiment of the invention is shown in the drawings and is described below. FIG.1 shows the top view of the machine from to recognize the two rows of laying heads arranged one behind the other and offset are.

Die Versetzung der einzelnen Legeköpfe (1) ist so ausgeführt, daß die einzelnen CFK- Bänder spaltlos nebeneinander zu liegen kommen. Während sich die von einer Rolle mit bestimmter Geschwindigkeit ablaufenden Legefolie (2) unter den Legeköpfen hindurchbewegt, wird dadurch, daß Legebeginn und Legeende der einzelnen Legeköpfe ansteuerbar ist, jede beliebige Flächenform mit CFK- Material belegt. Das CFK- Gelege (3) ist somit mit geringstem Materialverlust gelegt.The displacement of the individual laying heads (1) is designed so that the individual CFRP strips come to lie next to one another without any gaps. While underneath the laying film (2) running off a roll at a certain speed the laying heads moved through it is that the laying beginning and laying end of the individual Laying heads can be controlled, any surface shape is covered with CFRP material. The CFRP scrim (3) is thus laid with the lowest possible loss of material.

FIG.2 zeigt den Längsschnitt der Maschine und die Arbeitsweise der einzelnen Legeköpfe. Das auf Rollen (4) beziehbare, beiderseitig mit Schutzfolien versehene Bandmaterial wird durch das Ab zug srollenpaar (5) über eine Ausgleichsschwinge (6) mit der Geschwindigkeit des Transportbandes (7) und der mitlaufenden Legefolie (2) von der Rolle (4) abgezogen.FIG.2 shows the longitudinal section of the machine and the operation of the individual laying heads. The one available on rolls (4), with protective films on both sides provided tape material is by pulling the pair of rollers (5) over a compensating rocker (6) at the speed of the conveyor belt (7) and the accompanying sheet (2) pulled off the roll (4).

Der Antrieb erfolgt durch die Antriebswelle (8) über einen Zahnriemen. Eine Schaltkupplung (9) setzt bei einem Schaltsignal den Abroll- bzw. Legevorgang in Gang. Die beiden Schutzfolien werden durch die Rollenpaare (10) in Quertransportkanile (11) umgelenkt und seitlich abgeführt. Das vom Abrollwalzenpaar weitertransportierte CFK- Band wird von der Andrückrolle (12) erfaßt und auf die gleichlaufende Legefo lie (2) aufgerollt. Bei Signalende wird das Abrollwalzenpaar ausgekuppelt und der Legevorgang beendet. Gleichzeitig schneiden 3 Messer (13) das CFK- Band und die zwei Schutzfolien ab. Die Signaldauer ist ein Maß der ausgelegten Bandlänge. Darauf beruht die Wirkungsweise der dargestellten Erfindung.It is driven by the drive shaft (8) via a toothed belt. A clutch (9) sets the unrolling or laying process when a switching signal is received in progress. The two protective films are placed in transverse transport channels by the pairs of rollers (10) (11) deflected and discharged to the side. The one transported on by the pair of unwinding rollers CFRP tape is picked up by the pressure roller (12) and placed on the parallel laying sheet lie (2) rolled up. At the end of the signal, the pair of unwinding rollers is disengaged and the Laying finished. At the same time, 3 knives (13) cut the CFRP tape and the two protective films. The signal duration is a measure of the length of the tape. Thereon is based on the mode of operation of the invention shown.
