Abstract

A method for producing woven airbags, especially at least partially multi-layered airbags, includes the following steps: the warp threads are prepared in a warping room, warp threads which are suitable as marker threads for machine-readable markings being already placed in the warp; the airbag material is woven, weft threads which are suitable as marker threads for machine-readable markings being interlaced over at least part of the width of the cloth; and the airbag is cut out of the airbag material using a cutting device which is guided by the interlaced machine-readable markings.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen von gewebten, wenigstens teilweise mehrlagigen, Airbags, sowie ein Gewebe, insbesondere für teilweise mehrlagige Airbags.The present invention relates to a method for producing woven, at least partially multi-layered, airbags, as well as a fabric, in particular for partially multi-layered airbags.

JP-2000 15372 offenbart ein Verfahren zum Herstellen von gewebten Airbags, bei dem die Airbags aus dem Airbaggewebe mit einer Schneidvorrichtung ausgeschnitten werden. JP-2000 15372 discloses a method of making woven airbags in which the airbags are cut out of the airbag fabric with a cutting device.

Gewebe, insbesondere für teilweise mehrlagige Airbags, werden in der Regel nach dem Weben auf Zuschneidetischen zugeschnitten. Einstückig auf Webmaschinen gewebte, teilweise mehrlagige Airbags werden "one-piece-woven airbags" oder kurz "OPW" genannt. Die Lage und die Kontur der OPW in der von der Webmaschine kommenden Gewebebahn sollen Vorgabe für eine Zuschneideanlage sein.Fabrics, especially for partially multi-layered airbags, are usually cut to size on cutting tables after weaving. One-piece weave woven, partially multi-ply airbags are called "one-piece woven airbags" or "OPW" for short. The position and the contour of the OPW in the fabric web coming from the weaving machine should be the specification for a cutting machine.

Bei derzeit eingesetzten Airbag-Geweben, insbesondere für OPW, auch mehrlagig konturbezogen gewebten Luftsäcken ist eine Aktion oder Tätigkeit, abgestimmt auf eine jeweils vorliegende Kontur des Luftsackes im Gewebe, nur sehr schwer möglich. Der Einfachheit halber wird in dieser Beschreibung stets von OPW gesprochen, wobei Airbag-Gewebe, gewebte Luftsäcke und OPW gemeint sind. Die gewebte einlagige Kontur hebt sich beispielsweise kaum von gewebten zweilagigen Bereichen ab, so daß diese von automatischen Erfassungssystemen nicht sicher erkannt werden können.In currently used airbag fabrics, in particular for OPW, even multi-layer contour woven airbags, an action or activity, tailored to a particular contour of the airbag in the tissue, is very difficult. For the sake of simplicity, this description always refers to OPW, which means airbag fabric, woven air sacs, and OPW. The woven single-ply contour, for example, hardly stands out from woven two-ply areas, so that they can not be reliably detected by automatic detection systems.

Damit ergibt sich beim Zuschnitt von OPW beispielsweise folgende Problematik: Bei derzeit verwendeten Zuschnittsystemen für Airbag-Gewebe erfolgt der Zuschnitt der Einzelteil- oder Zuschnittsätze wie folgt: Aus den Kundenvorgaben wird über die Dimensionierung der einzelnen Teile manuell oder automatisch zum Beispiel über ein CAD-Programm eine Programmfolge für beispielsweise eine CNC-gesteuerte Schneidanlage erstellt, die beschreibt, wie die einzelnen Teile aus dem Airbag-Gewebe heraus geschnitten werden sollen. Das Schneiden erfolgt unabhängig vom jeweiligen Zustand des Gewebes, d.h. das Schneidelement bewegt sich relativ zu einem Referenzpunkt der Schneidanlage, unabhängig davon, wie und wo das Schneidgut der Anlage tatsächlich vorliegt. Das hat zur Folge, daß Abweichungen des Gewebes, insbesondere der Abmessungen von OPW nicht automatisch berücksichtigt werden können bzw. Anpassungen ein manuelles Eingreifen in die Programmfolge erforderlich machen, was in der Regel mit einem Maschinenstop, mit hohem Zeit- und damit Kostenaufwand für die Anpassung und bei (unter Umständen nicht korrekter) Programmweiterführung mit einem hohen Anteil an Ausschuß verbunden sein kann. Insbesondere bei OPW können deshalb, auch wegen unterschiedlicher maßlicher Abweichungen der jeweiligen Gewebepartien, insbesondere bei Artikeln mit äußerst kritischen Konturen, hohe Ausschußraten durch Konturverletzungen der Webkontur oder Einschnitte in eine Luftsackkammer bzw. Unter- oder Überschreitungen der vorgegebenen Toleranzen von der Schneidkante zu den Webkonturen auftreten.The following problem arises when cutting OPW, for example: In cutting systems for airbag fabrics currently used, the cutting of the individual part or cut-to-size sets is as follows: From the customer specifications, the dimensioning of the individual parts is done manually or automatically, for example via a CAD program created a program sequence for example, a CNC-controlled cutting system that describes how the individual parts of the airbag fabric to be cut out. The cutting takes place independently of the condition of the tissue, i. The cutting element moves relative to a reference point of the cutting system, regardless of how and where the material to be cut of the plant actually exists. This has the consequence that deviations of the fabric, in particular the dimensions of OPW can not be automatically taken into account or adjustments make a manual intervention in the program sequence required, which is usually a machine stop, with a high time and thus cost of adjustment and may be associated with a high proportion of committee in (possibly incorrect) program execution. Especially with OPW can therefore, also because of different dimensional deviations of the respective tissue sections, especially for articles with extremely critical contours, high reject rates due to contour violations of the web contour or cuts in an air bag chamber or undershoots or exceed the predetermined tolerances from the cutting edge to the web contours ,

Bei den in den o. g. Zuschnittsystemen im Einsatz befindlichen Online-Meßsystemen lassen sich Messungen an unausgeschnittenen OPW im Airbag-Gewebe an definierten Stellen nicht sicher durchführen, da die Webkonturen nicht sicher erkannt werden können. Zur Ermittlung der Werte müssen die Messungen, mit erheblichen Personalaufwand manuell durchgeführt werden.In the o. G. Cutting systems in online measuring systems in use can not reliably carry out measurements on uncut OPW in the airbag fabric at defined points, since the web contours can not be reliably detected. To determine the values, the measurements must be carried out manually with considerable personnel expenditure.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen von gewebten, insbesondere wenigstens teilweise mehrlagigen, Airbags, sowie ein Gewebe vorzuschlagen, wobei die aus dem Stand der Technik bekannten Nachteile vermieden oder zumindest stark reduziert werden.The present invention has for its object to provide a method for producing woven, in particular at least partially multi-layered, airbags, as well as a tissue, wherein the disadvantages known from the prior art are avoided or at least greatly reduced.

Die Aufgabe wird zum einen durch ein Verfahren nach Anspruch 1, zum anderen durch ein Gewebe gemäß Anspruch 2 gelöst. Das erfindungsgemäße Verfahren enthält folgende Verfahrenschritte:

  1. a) Vorbereiten der Kettfäden in der Schärerei, wobei als Kennfäden geeignete Kettfäden für maschinenlesbare Markierungen bereits in der Kettschar untergebracht werden,
  2. b) Weben des Airbaggewebes, wobei als Kennfäden geeignete Schußfäden für maschinenlesbare Markierungen über wenigstens einen Teil der Tuchbreite eingewebt werden,
  3. c) Ausschneiden der Airbags aus dem Airbaggewebe mit einer Schneidvorrichtung, wobei die Schneidvorrichtung von den eingewebten maschinenlesbaren Markierungen geführt wird.
The object is achieved on the one hand by a method according to claim 1, on the other hand by a fabric according to claim 2. The process according to the invention contains the following process steps:
  1. a) preparing the warp threads in the warp, whereby warp threads suitable for machine-readable markings are already accommodated as warp threads in the warp,
  2. b) weaving the airbag fabric, weft threads for machine-readable markings being woven over at least part of the width of the fabric as passwords,
  3. c) cutting out the airbags from the airbag fabric with a cutting device, wherein the cutting device is guided by the woven machine-readable markings.

Diese Verfahrensweise hat den großen Vorteil, daß durch die eingebrachten Markierungen sichergestellt wird, daß die dadurch erreichten Fixpunkte im Gewebe von Leseeinrichtungen maschinell gelesen und in nachfolgenden Prozeßschritten stets sicher erreicht werden. Mit diesem Verfahren, das jegliche gewünschte Position und Häufigkeit von Markierungen ermöglicht, ist man in der Lage, sowohl Kontur- als auch Dimensionsabweichungen in und zwischen den einezelnen in der Webbahn befindlichen Airbags beim Zuschnitt auszugleichen und darüberhinaus Fixpunkte nachfolgender Prozeßschritte sicher setzen zu können, und dies unabhängig von der Tatsache, daß ein Textil lebt und jede Airbagvariante andere Anforderungen setzt.This procedure has the great advantage that it is ensured by the introduced markers that the fixed points achieved in the tissue of reading devices are read by machine and always achieved safely in subsequent process steps. With this method, which allows any desired position and frequency of markings, one is able to compensate for both contour and dimensional deviations in and between the individual located in the weaving web airbags when cutting and beyond safe points of subsequent process steps safely set, and this is independent of the fact that a textile lives and every airbag variant sets different requirements.

Das erfindungsgemäße Verfahren, ist gekennzeichnet durch maschinenlesbare Markierungen zur Erkennung bestimmter Gewebepartien. Dabei werden Markierungen, beispielsweise einzelne oder mehrere farblich, durch Struktur, Material oder in sonst einer Weise vom Airbaggewebe sich unterscheidende Fäden, sogenannte Kennfäden, während dem Webprozeß eingewoben. Diese Kennfäden oder Markierungen ermöglichen in vorteilhafter Weise über definierte Soll-Abstände zueinander und die festgelegte Soll-Anordnung, bezogen auf einen OPW, in Verbindung zu den jeweiligen Ist-Abständen und der Ist-Anordnung, einen Rückschluß über die Form und/oder Größe und/oder Ausrichtung und/oder Verzug des zugeschnittenen OPW oder den OPW im ungeschnittenen Airbaggewebe, bzw. bieten Aufschluß über die Form und/oder Größe und/oder Ausrichtung und/oder Verzug des Zuschnitteils nach dem Schneidprozeß in folgenden Verfahrensschritten.The method according to the invention is characterized by machine-readable markings for the recognition of specific tissue parts. In this case, markings, for example, single or multiple color, by structure, material or in any other way from the airbag fabric differing threads, so-called Kennfäden, woven during the weaving process. These cords or markers allow in an advantageous manner over defined desired distances from each other and the specified target arrangement, based on an OPW, in conjunction with the respective actual distances and the actual arrangement, a conclusion about the shape and / or size and / or orientation and or distortion of the cut OPW or the OPW in the uncut airbag fabric, or provide information about the shape and / or size and / or orientation and / or distortion of the blank after the cutting process in the following steps.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further advantages and features of the invention will become apparent from the dependent claims.

Im folgenden wird die Erfindung in beispielhafter Weise anhand eines Herstellungsvorgangs für einen OPW beschrieben.In the following, the invention will be described by way of example with reference to a manufacturing process for an OPW.

Beim Vorbereiten der Kettfäden in der Schärerei, werden als Kennfäden geeignete Kettfäden für maschinenlesbare Markierungen bereits in der Kettschar untergebracht. Beim Weben des Airbaggewebes, werden als Kennfäden geeignete Schußfäden für maschinenlesbare Markierungen über wenigstens einen Teil der Tuchbreite eingewebt. Beim folgenden Ausschneiden der Airbags aus dem Airbaggewebe mit einer Schneidvorrichtung, wird die Schneidvorrichtung von den eingewebten maschinenlesbaren Markierungen geführt.When preparing the warp threads in the warp, suitable warp threads for machine-readable markings are already accommodated in the warp as identifiers. When weaving the airbag fabric, wefts suitable for machine-readable markings are woven over at least part of the width of the fabric as passwords. In the subsequent cutting out of the airbag from the airbag fabric with a cutting device, the cutting device is guided by the woven machine-readable markings.

Vor dem oder während dem Schneiden werden über ein entsprechendes System die Ist-Positionen dieser Fäden oder Markierungen ermittelt und mit den in einer Programmfolge für das Schneiden von OPW- oder Airbagteilen gespeicherten Soll-Positionen verglichen und die Differenzen für eine automatische Anpassung des Schneidprogramms (z.B. Resizing) verwendet.Before or during cutting, the actual positions of these threads or markings are determined via a corresponding system and compared with the desired positions stored in a program sequence for cutting OPW or airbag parts and the differences for an automatic adaptation of the cutting program (eg Resizing) used.

Es sind deshalb keine zeit- und damit kostenaufwendige manuelle Eingriffe mehr erforderlich. Über diese automatische Anpassung können engste maßliche Toleranzen eingehalten und äußerst kritische Konturen gefertigt werden. Maßliche Abweichungen innerhalb eines Webstückes oder zwischen einzelnen Webstücken können vor oder während des Schneidprozesses berücksichtigt werden. Dadurch wird der Anteil nichtverwendbarer Teile aufgrund von Konturverletzungen wesentlich reduziert.There are therefore no time-consuming and therefore costly manual intervention longer required. This automatic adjustment allows tight dimensional tolerances to be met and extremely critical contours to be made. Dimensional deviations within a weave or between individual weaves may be considered before or during the cutting process. As a result, the proportion of non-usable parts due to contour violations is significantly reduced.

Im folgenden wird die Erfindung in beispielhafter Weise anhand einer Maßerfassungsvorgangs für einen OPW beschrieben.The invention will now be described by way of example with reference to a measurement detection process for an OPW.

Die sehr personalintensive Vermessung der OPW, ungeschnitten im Airbag-Gewebe oder während oder nach dem Schneidprozeß, kann automatisch erfolgen. Die sich von dem OPW- bzw. Airbagmaterial abhebenden Kennfäden oder Markierungen können über ein Erfassungssystem erfaßt und der Status des OPW in Bezug auf die Form und/oder Größe und/oder Ausrichtung und/oder Verzug, über die Anordnung der Kennfäden oder Markierungen festgestellt werden. Die ermittelten Daten über die jeweils vorliegende Ware erlauben Rückschlüsse über den jeweiligen Zustand des OPW.The very personnel-intensive measurement of the OPW, uncut in the airbag fabric or during or after the cutting process, can be done automatically. The distinguishing from the OPW or airbag material cues or markers can be detected via a detection system and the status of the OPW with respect to the shape and / or size and / or orientation and / or distortion, on the arrangement of the cords or markers are determined , The data obtained on the goods in each case allow conclusions about the current state of the OPW.

Im folgenden werden zwei Beispiele des Gewebes kurz beschrieben.In the following, two examples of the fabric will be briefly described.

Fig. 1 zeigt schematisch einen Gewebeausschnitt mit aufgedruckten Markierungen der nicht unter die beansprüchte Erfindung fällt. Fig. 1 schematically shows a tissue cutout with printed markings not falling under the claimed invention.

Fig. 2 zeigt schematisch einen Gewebeausschnitt mit eingewebten Markierungen. Fig. 2 schematically shows a tissue section with woven markings.

In den Ausführungsbeispielen sind zwei Varianten von Markierungen gezeigt. Fig. 1 zeigt ein OPW Gewebe 1 mit aufgedruckten Markierungen 2, die auf die gewebte Kontur 4 abgestimmt sind.In the exemplary embodiments, two variants of markings are shown. Fig. 1 shows an OPW fabric 1 with printed markings 2, which are matched to the woven contour 4.

Fig. 2 zeigt ein OPW-Gewebe 1a in dem gegenüber dem Grundmaterial andersartige Kennfäden 2a, vor oder während des Webprozesses, eingebracht wurden, die auf die gewebten Konturen 4a abgestimmt sind. Fig. 2 shows an OPW fabric 1 a in the opposite to the base material different yarns 2 a, before or during the weaving process, were introduced, which are matched to the woven contours 4 a.

Die vor, während oder nach dem Webprozeß auf das Gewebe oder die gewebte Kontur eines OPW abgestimmten auf- oder eingebrachten Markierungen, z.B. durch Aufdruck oder Kennfäden, dienen zur Anpassung nachfolgender Prozesse auf die Webkontur oder das Gewebe als Referenzpunkte, insbesondere zur Erkennung von gewebten Konturen der OPW und die darauf abgestimmte Korrektur der nachfolgenden Prozeßschritte.The applied before, during or after the weaving process on the tissue or the woven contour of an OPW attached or incorporated markers, e.g. by imprint or characteristic threads, are used to adapt subsequent processes to the web contour or the tissue as reference points, in particular for the detection of woven contours of the OPW and the coordinated correction of the subsequent process steps.
