Description
Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Für die Herstellung von lang- bzw. endlosfaserverstärkten Faser-Kunststoff- Verbundwerkstoffen (FKV) werden Lagenpakete, bestehend aus flächigen, z. T. textilen, Verstärkungshalbzeugen aufeinander gestapelt. Für die Fertigung von endkonturgenauen Bauteilen müssen diese Pakete dabei bereits auf Endmaß gearbeitet vorliegen.For the production of long or continuous fiber reinforced fiber-plastic Composite materials (FKV) are layer packages consisting of flat, e.g. T. textile, Reinforced semi-finished products stacked on top of each other. For the production of precise final contours Components must have these packages already worked to their final dimensions.
Bauteile mit beliebigen Faser-Orientierungen (innerhalb der gegebenen textilen Faser- Halbzeugen) werden aus mehreren Einzellagen so aufgebaut, daß der gewünschte Lagen aufbau entsteht. Dies geschieht bekannterweise im Prepregverfahren. Für Harzinjektions verfahren werden solche Lagenaufbauten auch mit trockenen Faser-Halbzeugen realisiert. Im Falle der Harzinjektionsverfahren wird, aufgrund der Ausfransproblematik mit Über maß gearbeitet. Es entsteht Verschnitt zum einen durch die an den Prozeß anschließende mech. Bearbeitung und zweitens durch die nur schwer zu realisierende Weiterverwendung der unmittelbar an den Ausbruch angrenzenden Flächen des textilen Halbzeugs. Die Ver wendung sogenannter Faser-Preforms, die in verschiedenen Technologien (Offenlegungs schrift DE 196 24 912 A1, Hörsting, K.-H.; Offenlegungsschrift DE 197 16 666 A1, Feltin, D.; Offenlegungsschrift, DE 196 28 388 A1, Gliesche, K.) hergestellt werden können, re duziert die Zahl der Einzellagenzuschnitte und ermöglicht eine endkonturgenaue Fertigung einzelner Kanten.Components with any fiber orientation (within the given textile fiber Semi-finished products) are constructed from several individual layers so that the desired layers construction arises. This is known to take place in the prepreg process. For resin injection Such layer structures are also implemented with dry semi-finished fiber products. In the case of resin injection processes, due to the fraying problem with over made to measure. On the one hand, waste is created by the one that follows the process mech. Processing and secondly due to the difficult to implement further use the areas of the semi-finished textile immediately adjacent to the outbreak. The Ver Use of so-called fiber preforms that are used in various technologies (disclosure document DE 196 24 912 A1, Hörsting, K.-H .; Laid-open specification DE 197 16 666 A1, Feltin, D .; Offenlegungsschrift, DE 196 28 388 A1, Gliesche, K.) can be produced, right reduces the number of single-layer cuts and enables final contour-accurate production single edges.
Die zur Herstellung von solchen Lagenpaketen benötigten Einzellagen-Zuchnitte sind kaum handhabbar. Abhängig von der Art des textilen Halbzeugs verliert ein solcher Zu schnitt ein Großteil seiner äußeren Verstärkungsfäden. Die Festigkeit in den Kanten eines Bauteils ist somit nicht vorhersagbar. In der Fläche, aus der der Einzelzuschnitt entnom men wurde, entsteht die gleiche Problematik, so daß eine Verschnittsoptimierung beim Zuschneiden nur bedingt umgesetzt werden kann. Durch die Notwendigkeit verschiedener textiler, flächiger Halbzeuge (1/1-Leinwand-Gewebe, ±45°-Gelege, ±30°-Gelege, . . .) ist die Kennzeichnung jeder einzelnen Lage vorzunehmen. Die Automatisierung einer solcher Fertigung ist somit nicht zu realisieren. Neue Preformtechnologien mittels Binder, Näh- oder sonstigen Textiltechniken haben die Herstellung von bauteilgerechten Faser- Vorformlingen zum Ziel. Diese Verfahren konzentrieren sich auf die Herstellung der Bau teil-Kontur (z. B. Profile L-Z) jedoch nicht der Begrenzungskanten. Durch die somit not wendige mechanische Nachbearbeitung werden Fehlstellen, z. B. durch die dynamische Belastung beim Fräsen, in das Laminat eingebracht. Solche bearbeiteten Kanten sind nicht geschlossen, was die Chemikalienbeständigkeit beeinträchtigt. Sind solche "Bezugskanten" nicht mit einer geringen Toleranz vorhanden, ist es unmöglich Funktionselemente, wie z. B. Krafteinleitungselemente exakt auf der trockenen Struktur zu positionieren.The individual ply cuts required for the production of such ply packages are hardly manageable. Depending on the type of semi-finished textile, such a looses cut most of its outer reinforcement threads. The strength in the edges of a The component is therefore unpredictable. In the area from which the single cut is taken men, the same problem arises, so that a blending optimization when Cropping can only be implemented to a limited extent. Because of the need for different textile, flat semifinished products (1/1 canvas fabric, ± 45 ° scrim, ± 30 ° scrim,...) is the To mark each individual layer. The automation of such Manufacturing is therefore not possible. New preform technologies using binders, sewing or other textile technologies have the production of component-specific fiber Preforms to the target. These processes focus on the manufacture of the construction partial contour (e.g. profiles L-Z) but not the boundary edges. Through the thus not Agile mechanical post-processing will have defects, e.g. B. by the dynamic Load during milling, introduced into the laminate. Such machined edges are not closed, which affects the chemical resistance. Are such "reference edges" not available with a small tolerance, it is impossible functional elements, such as B. Position force application elements exactly on the dry structure.
Verschnittsoptimale Zuschnitte in der Textil- oder Bekleidungsbranche sind Stand der Technik, jedoch werden hier schiebefeste und nicht ausfransende textile Halbzeuge verar beitet.Cutting blanks in the textile or clothing industry are state of the art Technology, however, non-slip and non-fraying semi-finished textile products are processed here works.
Aufgabe der Erfindung ist die Vorbereitung von trockenen textilen Verstärkungsstrukturen zur paßgenauen Weiterverarbeitung der Einzelteile zu Lagenaufbauten mit beliebig ein stellbarer Faser-Orientierung und sehr genauer Maßgenauigkeit. Weiterhin soll das Verfah ren die eingesetzten textilen Halbzeuge ohne Verschnitt für folgende Preform- Operationen vorbereiten, d. h. eine Kantenstabilität soll gewährleistet sein. Das Verfahren soll verschnittsoptimierte Zuschnitte aus flächigen Halbzeugen erzeugen und somit die Effizienz des Preformings erhöhen. Aufnahmen zur Integration weiterer Elemente in die Preform können vorgesehen werden.The object of the invention is the preparation of dry textile reinforcement structures for precisely fitting further processing of the individual parts to layer structures with any adjustable fiber orientation and very precise dimensional accuracy. Furthermore, the procedure the textile semi-finished products used without waste for the following preform Prepare operations, d. H. edge stability should be guaranteed. The procedure should produce cut-optimized blanks from flat semi-finished products and thus the Increase the efficiency of preforming. Recordings for the integration of further elements in the Preforms can be provided.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a method having the features of claim 1.
Mittels einer Kombination aus 2 parallelen Nähten auf der textilen Verstärkungsstruktur und einem Zuschneidesystem, daß zwischen den beiden Nähten den Ausschnitt erzeugt (in Reihe oder einem folgenden Prozeß), entstehen exakte nicht ausfransende Einzelteile. Gleichzeitig kann das Halbzeug durch die Vermeidung des Ausfransens verschnittsopti miert genutzt werden. Die Nähte schaffen exakte Randbedingungen und bieten die nötige Schiebefestigkeit die zum Schneiden notwendig ist. Durch den drehbaren Nähkopf können auch Ausbrüche (z. B. Löcher) in der textilen Struktur erzeugt werden.Using a combination of 2 parallel seams on the textile reinforcement structure and a trimming system that creates the cutout between the two seams (in Series or a subsequent process), exact non-fraying individual parts arise. At the same time, the semi-finished product can be cut by avoiding fraying used. The seams create exact boundary conditions and provide the necessary ones Slip resistance necessary for cutting. Thanks to the rotating sewing head breakouts (e.g. holes) can also be generated in the textile structure.
Bauteilgeometrien können aus dem textilen Halbzeug ausgeschnitten werden, ohne Entste hung weiteren Verschnitts durch anschließende Verarbeitungsprozesse am Zuschnitt. Da durch wird ein komplett maßgenauer Faser-Vormformling für FKV Bauteile möglich. Fa serorientierungen können durch die Verwendung mehrerer textiler Halbzeugtypen gezielt eingestellt, und somit das Leichtbaupotential dieser Werkstoffe in einem hohen Maße ge nutzt, werden. Der Einsatz von Handling-Systemen wird durch die definierten Maße und die Randfixierung möglich. Inserts können dementsprechend positionsgenau fixiert wer den. Ebenso ist es möglich mittels einer Endvernähung exakt lokale Funktionen in die Pre form einzubringen (z. B. Zonen hoher Impactbelastung oder Fließkanäle zur Steuerung der Fließfront bei der Harzinjektion).Component geometries can be cut out of the semi-finished textile, without creating anything further cutting through subsequent processing on the cut. There This enables a completely accurate fiber preform for FKV components. Company Orientations can be targeted by using several types of textile semi-finished products set, and thus the lightweight potential of these materials to a high degree uses, will. The use of handling systems is determined by the defined dimensions and the edge fixation possible. Accordingly, inserts can be fixed in position the. It is also possible by means of a final sewing to precisely local functions in the pre form (e.g. zones with high impact loads or flow channels to control the Flow front with resin injection).
Variierte Nähparameter ermöglichen eine Einstellbarkeit der Kantensteifigkeit. Diese kön nen jeweils den Anforderungen des Folgeprozesses angepaßt werden. Varying sewing parameters enable the edge stiffness to be adjusted. These can can be adapted to the requirements of the subsequent process.

Zur Herstellung einer Schwinge aus Faser-Kunststoff-Verbundwerkstoff (FKV) im Har zinjektionsverfahren wird ein spezieller Lagenaufbau benötigt. Dieser setzt sich aus ver schiedenen in der Ebene Orthogonale Lagen eines textilen Halbzeugs zusammen (Fig. 1). In der Ebene des textilen Halbzeugs (1) wird die Kontur mit einer Doppel-Naht (2) abge näht, dabei können die Faser-Orientierungen im Rahmen der Orthogonalität des textilen Halbzeugs beliebig eingestellt werden. ±45°-Grad-Lagen (3) und 0/90-Grad-Lagen (4) werden verschnittsoptimiert auf die Ebene projiziert. Weiterhin werden die zur Aufnahmen von Krafteinleitungselementen vorgesehenen Ausbrüche im Halbzeug (5) vorgesehen. Der auf Lochleibung beanspruchte Teil des Bauteils wird mit einer Z-Verstärkung versehen. Aufdoppler (6) zur Verstärkung des Augenbereichs werden im gleichen Verfahren herge stellt.A special layer structure is required to manufacture a swing arm made of fiber-plastic composite (FKV) using the resin injection process. This is composed of different orthogonal layers of a semi-finished textile ( Fig. 1). In the plane of the semi-finished textile ( 1 ) the contour is sewn off with a double seam ( 2 ), the fiber orientations can be set as desired within the orthogonality of the semi-finished textile. ± 45 ° degrees ( 3 ) and 0/90 degrees ( 4 ) are projected onto the plane in a blend-optimized manner. Furthermore, the outbreaks provided for receiving force introduction elements are provided in the semi-finished product ( 5 ). The part of the component that is exposed to the reveal is provided with a Z-reinforcement. Duplicators ( 6 ) for strengthening the eye area are produced in the same process.
Mittels der in Fig. 2 beschriebenen Anlage werden die benötigten Einzellagen endkontur genau hergestellt, indem mittels eines 2-Nadel-Nähkopfes (7) die Kontur der Schwinge (8) exakt auf jedem benötigten Faser-Halbzeug (9) und mit jeder benötigten Faser- Orientierung abgenäht wird, und eine Schneidvorrichtung (10) entlang der Doppelnaht, zwischen den beiden Nähten die Kontur ausschneidet. Ein Handling-System (11) greift diese Zuschnitte und legt sie am Bestimmungsort, dem Preform-Träger (12), ab. Dort kön nen die Pakete u. U. nochmals zu einem handhabbaren Preform-Paket vernäht werden. Es kann sowohl ein komplizierter Lagenaufbau abgelegt werden, als auch das Einzelteil einer maßgenauen Endmontage zur 3D-Preform zugeführt werden. Bei der Ablage mehrerer Einzelteile in eine Form, werden an die Naht keine größeren Anforderungen gestellt. Folgt, wie bereits erwähnt, eine Montage der verschiedenen Einzelteile, so muß die Kantenstabilität hoch sein, um so eine exakte 3D-Preform mit geringen Toleranzen zu erhalten. Lokale Aufdoppler (13), z. B. zur Verstärkung der Augenbereiche einer Schwinge, werden im glei chen Verfahren hergestellt, hier wird der Fixiergrad der Kanten durch variierte Nähpara meter erhöht.By means of the system described in FIG. 2, the required individual layers of final contour are precisely produced by using a 2-needle sewing head ( 7 ) to precisely contour the rocker ( 8 ) on each required semi-finished fiber product ( 9 ) and with each required fiber Orientation is sewn off, and a cutting device ( 10 ) along the double seam cuts out the contour between the two seams. A handling system ( 11 ) grips these blanks and places them at the destination, the preform carrier ( 12 ). There the packages u. U. sewn again to a manageable preform package. A complicated layer structure can be stored, as well as the individual part can be fed to a dimensionally accurate final assembly for 3D preform. When storing several individual parts in one form, no major requirements are placed on the seam. If, as already mentioned, the various individual parts are assembled, the edge stability must be high in order to obtain an exact 3D preform with small tolerances. Local doublers ( 13 ), e.g. B. to reinforce the eye areas of a rocker are manufactured in the same process, here the degree of fixation of the edges is increased by varying sewing parameters.
In Fig. 3 ist das System des Abnähens und des Zuschneidens in der Ebene zu erkennen. Der 2-Nadel-Nähkopf ist drehbar gelagert (14), Nährichtung und Nahtbilder sind frei pro grammierbar. Die gleiche Bahn fährt, im Anschluß an den Nähkopf, auch ein Zuschneide kopf (15) ab. Die eingesetzten textilen Halbzeuge (16) sind Standard-Halbzeuge, wie z. B. Bi-Axial, Tri-Axial, Quadraxial-Gelege, oder Gewebe. Ist eine solche Doppel-Naht nicht zum Erreichen der notwendigen Kantenstabilität ausreichend, können auch 4- oder Mehr- Nadel-Maschinen eingesetzt werden. The system of sewing and cutting in the plane can be seen in FIG . The 2-needle sewing head is rotatably supported ( 14 ), sewing direction and seam patterns are freely programmable. The same path runs, following the sewing head, also a trimming head ( 15 ). The textile semi-finished products ( 16 ) are standard semi-finished products, such as. B. Bi-Axial, Tri-Axial, Quadraxial-scrims, or fabric. If such a double seam is not sufficient to achieve the necessary edge stability, 4 or more needle machines can also be used.
Es entstehen Einzelteile, die dem Endmaß des Bauteils entsprechen (Fig. 4) (17) und zur komplexen Preform weiterverarbeitet werden können. Das Ausfransen ist durch eine Naht (18) im Randbereich des Einzelteils verhindert. Der Grad der Fixierung dieser Kante hängt von den Nähparametern ab. Zur Aufnahme von Krafteinleitungsbuchsen wird ein Aus bruch (19) erzeugt, der mit einer Doppel- (20) oder Mehrfach-Naht (21) erzeugt, geschnit ten und gesichert ist.Individual parts are produced which correspond to the final dimension of the component ( Fig. 4) ( 17 ) and can be further processed to form a complex preform. Fraying is prevented by a seam ( 18 ) in the edge area of the individual part. The degree of fixation of this edge depends on the sewing parameters. To accommodate force transmission bushings, an outbreak ( 19 ) is generated, which is produced, cut and secured with a double ( 20 ) or multiple seam ( 21 ).
Die flächigen, textilen Halbzeuge werden nach der Entnahme der Einzelteile verschnitts optimiert, d. h. Minimierung des Verschnitts, weiterverwendet. Fig. 5 zeigt das textile Halbzeug nach der Entnahme eines Einzelteils. Die Naht (22) fixiert das Gelege und ver hindert das Ausfransen. Die freien Flächen in der Umgebung des Ausschnittes (23) stehen für nachfolgende Einzelteile komplett zur Verfügung.The flat, semi-finished textile products are optimized after the individual parts have been removed, ie the waste is minimized. Fig. 5 shows the semi-finished textile after removal of an item. The seam ( 22 ) fixes the fabric and prevents fraying. The free areas in the vicinity of the cutout ( 23 ) are completely available for subsequent individual parts.
Der Vorgang wird solange wiederholt bis die komplette Preform fertiggestellt ist. Der Vorgang kann vollautomatisiert erfolgen.The process is repeated until the complete preform is completed. The The process can be fully automated.
Zur Weiterverarbeitung der so hergestellten Einzelteile können verschiedene Preforming- Prozesse (Offenlegungsschrift DE 196 08 127 A1, Drechsler, K.) eingesetzt werden.Various preforming Processes (published application DE 196 08 127 A1, Drechsler, K.) are used.
