Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Optimierung von Garnen und Geweben aufgrund gemessener Garndaten sowie das zugehörige Optimierungsverfahren.The present invention relates to a device for optimizing yarns and fabrics based on measured yarn data and the associated optimization process.

Die Entwicklung neuer Gewebe erfolgt üblicherweise mit CAD-Systemen. Diese bekannten CAD-Systeme gestatten, neue Gewebe unter Veränderung einer Vielzahl von Parametern zu entwickeln. Grundlage für die Berechnung in CAD-Systemen sind jedoch immer "ideale" Garne, d.h. Garne, deren Durchmesser, Feinheit, Reißfestigkeit über das gesamte Garn konstant ist.New fabrics are usually developed using CAD systems. This known CAD systems allow new tissues by changing a variety of developing parameters. Basis for the calculation in CAD systems however, are always "ideal" yarns, i.e. Yarns whose diameter, Fineness, tensile strength is constant over the entire yarn.

Bei realen Garnen sind jedoch die Garndurchmesser und sonstige Garneigenschaften nicht, wie bei dem "idealen Garn", über die Gamlänge konstant. So weisen reale Garne Dünnstellen, Dickstellen, Nissen etc. auf, die sich natürlich auf die Optik des späteren "Realgewebes" auswirken, aber bei der Gewebeentwicklung auf dem CAD-System nicht berücksichtigt werden. Dies führt dazu, daß häufig das erhaltene reale Gewebe nicht der Vorstellung des Designers entspricht.With real yarns, however, the yarn diameter and other yarn properties are not, as with the "ideal yarn", constant over the thread length. So point real yarn thin spots, thick spots, nits etc., which naturally affect the Effects of the later "real tissue", but in tissue development are not taken into account on the CAD system. This often means that preserved real fabric does not correspond to the designer's idea.

Eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist aus EP-A-0 692 562 bekannt.A device according to the preamble of claim 1 is from EP-A-0 692 562 known.

Die Aufgabe der Erfindung besteht darin, die Systeme zur Entwicklung neuer Gewebe zu verbessern und/oder Maschineneinstellungen bzw. Prozesse bei der Garnherstellung zu optimieren. The object of the invention is to develop new tissue systems to improve and / or machine settings or processes in the Optimize yarn production.

Diese Aufgabe wird dadurch gelöst, daß eine Vorrichtung bereitgestellt wird, die ermöglicht, bei dem Design des Gewebes die realen Werte des jeweiligen Garns zu berücksichtigen und die zugleich eine Anpassung und/oder Veränderung der Bindung bzw. jeder beliebigen Verkreuzungsstelle unter Berücksichtigung des optischen Erscheinungsbildes eines jeden Garnes ermöglicht.This object is achieved in that a device is provided which enables the real values of the respective yarn in the design of the fabric to take into account and at the same time an adjustment and / or change of the Binding or any intersection taking into account the optical Appearance of each yarn.

Mit der erfindungsgemäßen Vorrichtung ist es möglich, durch Veränderungen einer jeden Verkreuzung Dünn-, Dickstellen oder Nissen hervorzuheben oder optisch in den Hintergrund treten zu lassen. In manchen Geweben sind gerade die optischen Effekte, die durch unregelmäßige Garne erzielt werden, gewünscht, und durch die freie Definierbarkeit der Bindung wird ermöglicht, bei gewünschten Unregelmäßigkeiten diese durch die Art der jeweiligen Bindung optisch zu unterstreichen.With the device according to the invention it is possible to change a to highlight any intersection of thin, thick or nits or optically to take a back seat. In some fabrics they are optical effects, which are achieved by irregular yarns, and the free definability of the binding enables the desired irregularities to emphasize this visually by the type of binding.

In der erfindungsgemäßen Vorrichtung wird der Garndurchmesser des jeweiligen individuellen Garns optoelektronisch vermessen. Aufgrund der definierten Art der gewünschten Bindung wird unter Berücksichtigung der individuellen Meßwerte der Garne eine dreidimensionale Darstellung des Realgewebes berechnet und visualisiert. Jede beliebige Verkreuzung kann - vorzugsweise über eine schematisierte Darstellung des Gewebes auf einem Bildschirm und Eingabe mit der Tastatur oder einer Maus - verändert werden. Das reale Gewebe kann wiederum visualisiert und so lange geändert werden, bis das gewünschte Design erhalten ist.In the device according to the invention, the yarn diameter of the respective measure individual yarns optoelectronically. Due to the defined type of desired binding is taken into account taking into account the individual measurements A three-dimensional representation of the real fabric is calculated and visualized. Any crossing can - preferably via a schematic Representation of the fabric on a screen and input using the keyboard or a mouse - be changed. The real tissue can in turn be visualized and be changed until the desired design is obtained.

Durch die dreidimensionale Darstellung des Realgewebes werden auch erhebliche Mengen an Garn, Maschinen, Strom und Arbeitszeit eingespart, da es nicht mehr erforderlich ist, die Webmaschine einzuschalten, um zu sehen, wie das Realgewebe aussieht, um es dann ggf. als Ausschuß zu deklarieren.The three-dimensional representation of the real tissue also becomes significant Amounts of yarn, machinery, electricity and labor saved as it no longer it is necessary to turn on the weaving machine to see how the real fabric looks like, to declare it as a committee if necessary.

Zur Verringerung des Ausschusses trägt auch die Kombination der Bindungseingabevorrichtung mit der freien Wählbarkeit der Webdichte bei.The combination of the binding input device also contributes to reducing the waste with the free choice of weaving density.

Weiterhin ist es in einer besonderen Ausführungsform möglich, in der erfindungsgemäßen Vorrichtung auch die Farben entlang eines Garnes zu messen und in die Auswertevorrichtung zu übermitteln, so daß neben den realen Garndurchmessern auch die realen Farben bei der Berechnung des Realgewebes berücksichtigt werden können. Furthermore, it is possible in a special embodiment in the inventive Device also to measure and in the colors along a yarn to transmit the evaluation device so that in addition to the real yarn diameters the real colors are also taken into account when calculating the real fabric can be.

Die Erfindung wird nun anhand eines Ausführungsbeispiels näher erläutert:

  • Fig. 1 zeigt den Aufbau der erfindungsgemäßen Vorrichtung zur Optimierung von Realgeweben aufgrund gemessener Gamdaten.
    • The invention will now be explained in more detail using an exemplary embodiment:
  • 1 shows the structure of the device according to the invention for optimizing real tissues on the basis of measured gam data.

    • Die Vorrichtung 11 umfaßt ein Meßgerät 12, das zur Messung des Garndurchmessers dient, eine Bindungseingabevorrichtung 13, in der die jeweilige gewünschte Bindung frei definiert und auch geändert werden kann, eine Ansteuerungs- und Auswertevorrichtung 14 und eine Anzeigevorrichtung 16, insbesondere einen Bildschirm.The device 11 comprises a measuring device 12, which is used to measure the yarn diameter serves, a binding input device 13, in which the respective desired Binding freely defined and can also be changed, a control and evaluation device 14 and a display device 16, in particular a screen.

    Die Messung des Garndurchmessers im Meßgerät 12 erfolgt im Meßkopf, der nach dem absolut messenden optischen Prinzip arbeitet. Vorteil der absoluten optoelektronischen Messung ist, daß die Messung unempfindlich gegenüber Lichtquellenalterung, Fremdlicht, Verschmutzung, Temperatur und Feuchtigkeit ist und von Farbe, Leitfähigkeit und Glanz des zu messenden Garnes nicht abhängt. Auch ist bei solch einer Messung keine ständige neue Kalibrierung und Eingabe von Parametern erforderlich.The measurement of the yarn diameter in the measuring device 12 takes place in the measuring head, the works on the absolutely measuring optical principle. Advantage of absolute optoelectronic measurement is that the measurement is insensitive to Light source aging, extraneous light, pollution, temperature and humidity is and does not depend on the color, conductivity and gloss of the yarn to be measured. Also with such a measurement there is no constant new calibration and input of parameters required.

    Im allgemeinen ist es für die Messung von Naturgarnen ausreichend, einen Meßkopf zu verwenden, der in einer Genauigkeit von 0,1 mm mißt. Je nach Art des zu messenden Garnes, beispielsweise bei Chemiefasergarnen oder auch in Einzelfällen bei Naturfasergarnen, werden bevorzugt Meßköpfe in einer Genauigkeit von mindestens 0,01 mm eingesetzt.In general, it is sufficient for the measurement of natural yarns to have a measuring head to be used, which measures with an accuracy of 0.1 mm. Depending on the type of measuring yarns, for example in synthetic yarns or in individual cases in natural fiber yarns, measuring heads with an accuracy of at least 0.01 mm.

    Neben dem Meßkopf umfaßt das Meßgerät 12 eine Garnzuführung und Elektronik.In addition to the measuring head, the measuring device 12 includes a yarn feed and electronics.

    Solche Meßköpfe sind dem Stand der Technik bekannt und werden beispielsweise von BARCO/Belgien vertrieben.Such measuring heads are known in the prior art and are used, for example distributed by BARCO / Belgium.

    Für die erfindungsgemäße Optimierungsvorrichtung ist es erforderlich, daß die Genauigkeit der Garndurchmessermessung wenigstens 1/100 mm beträgt. Die Messung des Durchmessers des Garnes sollte wenigstens alle 2 mm erfolgen.For the optimization device according to the invention, it is necessary that the Accuracy of the yarn diameter measurement is at least 1/100 mm. The The diameter of the yarn should be measured at least every 2 mm.

    Die im Meßgerät 12 ermittelten Meßwerte werden nun in die Auswertevorrichtung 14 über eine parallele Schnittstelle 19 übermittelt. Die Auswertevorrichtung 14 steuert zugleich das Meßgerät 12 über eine serielle Schnittstelle 21. The measured values determined in the measuring device 12 are now in the evaluation device 14 transmitted via a parallel interface 19. The evaluation device 14 controls the measuring device 12 at the same time via a serial interface 21.

    Mit der Vorrichtung 14 ist auch die Vorrichtung 13 zur Eingabe und Änderung frei definierbarer Bindungen verbunden. In der Bindungseingabevorrichtung 13 kann jedwede mögliche Art der Verkreuzung der Fadengruppen definiert werden. Vorzugsweise sind dies Flachgewebebindungen. Über einen Zugriff auf bereits definierte Bindungen ermöglicht diese Vorrichtung eine individuelle Definition jeder gewünschten Bindung und eine Veränderung bereits bestehender Bindungen an beliebig vielen Verkreuzungen. Die Eingabe und Änderung der jeweiligen Bindung erfolgt am einfachsten über einen PC durch Markierung der jeweiligen, auf einem Bildschirm angezeigten Verkreuzungspunkte, beispielsweise mit einer Maus oder über die Tastatur.With the device 14, the device 13 is also free for input and change definable bonds. In the binding input device 13 can any possible way of crossing the thread groups can be defined. Preferably these are flat weaves. By accessing already defined ones This device allows for an individual definition of bindings desired binding and a change to existing bindings any number of crossings. Entering and changing the respective binding The easiest way is via a PC by marking the respective one on a Crossing points displayed on the screen, for example with a mouse or over the keyboard.

    Vorzugsweise ist die Bindungseingabevorrichtung 13 zusammen mit der Steuerund Auswertevorrichtung 14 in einem Computer integriert.Preferably, the binding input device 13 is together with the control and Evaluation device 14 integrated in a computer.

    Nachdem die Messung des jeweiligen Garns in dem Gerät 12 erfolgt und eine Bindung in der Vorrichtung 13 definiert ist, erfolgt in der Vorrichtung 14 die Berechnung der dreidimensionalen Darstellung des Realgewebes aufgrund der frei definierten Bindung und den gemessenen Garndurchmessern. Die Darstellung erfolgt auf einem mit der Auswertevorrichtung 14 verbundenen Bildschirm 16. Wahlweise kann an die Auswertevorrichtung 14 eine Ausgabevorrichtung 17 angeschlossen sein.After the measurement of the respective yarn in the device 12 and a Binding is defined in the device 13, the calculation takes place in the device 14 the three-dimensional representation of the real tissue due to the free defined binding and the measured yarn diameter. The representation takes place on a screen 16 connected to the evaluation device 14. An output device 17 can optionally be connected to the evaluation device 14 his.

    Entlang von Raumkurven werden die gemessenen Daten visualisiert, wobei Helligkeitsverlauf (Schattenwirkung) und Farbe berücksichtigt und eine Verdeckungsrechnung der Fäden durchgeführt wird. Bei der Visualisierung können Lichteinstellungen, Kameraposition und Brennweite verändert werden.The measured data are visualized along room curves, with the brightness curve (Shadow effect) and color and a masking calculation the threads are carried out. In the visualization, light settings, Camera position and focal length can be changed.

    Die Darstellung am Bildschirm erfolgt vorzugsweise durch Parallelprojektion des Objekts mittels einer 3D-Graphikbibliothek. Es sind jedoch auch andere Projektionen möglich.The display on the screen is preferably carried out by parallel projection of the Object using a 3D graphics library. However, there are other projections possible.

    Natürlich müssen für die Berechnung des Realgewebes auch die Parameter der Webmaschine (Gewebegröße) eingegeben sowie Kett- und Schußfäden zugeordnet werden, damit das berechnete Realgewebe auch wirklich dem später gewebten Ergebnis entspricht. Of course, the parameters of the Weaving machine (fabric size) entered and assigned warp and weft threads so that the calculated real fabric is really the one that will be woven later Result corresponds.

    Aufgrund dieser dreidimensionalen Darstellung des Realgewebes können nun einzelne Bindungen verändert werden, um ein individuelles Gewebe herzustellen, bei dem spezifische Dünnstellen, Dickstellen und/oder Nissen durch die individuelle Art der Verkreuzung der Fäden in der Gewebestruktur stärker hervorgehoben werden oder in den Hintergrund treten. Zu Dokumentationszwecken kann die dreidimensionale Darstellung des optimierten Realgewebes dann auf einem Drucker oder Kopierer 17, vorzugsweise in Farbe, ausgegeben werden.Because of this three-dimensional representation of the real tissue can now individual bonds are changed to produce an individual fabric, in the case of the specific thin spots, thick spots and / or nits by the individual The type of crossing of the threads in the fabric structure is more emphasized become or take a back seat. For documentation purposes, the three-dimensional The optimized real fabric is then displayed on a printer or copier 17, preferably in color.

    Falls gewünscht, können die Meßwerte auch statistisch ausgewertet werden. Die statistische Auswertung ermöglicht Aussagen über die Qualität der Game.If desired, the measured values can also be statistically evaluated. The statistical evaluation allows statements about the quality of the game.

    Die Statistikfunktionen sollten neben einer jederzeit möglichen statistischen Auswertung eines einzelnen gemessenen Garns auch statistische Auswertung über Gesamtsummen von Meßreihen einzelner Garne und/oder frei definier- und auswählbare Einzelmessungen von Garnen umfassen und Mittelwerte, Standardabweichungen, Varianzen und sonstige statistische Auswertungen der gemessenen Einzelgarne und/oder Gruppen von Garnen ermöglichen. Auch ist eine zwei und/oder dreidimensionale graphische Darstellung der jeweilig gewünschten Statistikfunktionen vorgesehen.The statistical functions should include a statistical evaluation that is possible at any time of a single measured yarn also statistical evaluation over Totals of measurement series of individual yarns and / or freely definable and selectable Individual measurements of yarns include and mean values, standard deviations, Variances and other statistical evaluations of the measured Allow single yarns and / or groups of yarns. Also one is two and / or three-dimensional graphical representation of the respectively desired statistical functions intended.

    Vorzugsweise erfolgt die Farbauswahl für jedes gewünschte reale und/oder ideale Garn über Eingabe der jeweils gewünschten Rot-Grün-Blau-Werte, so daß frei definier- und wählbare Farben zur Verfügung stehen.The color selection is preferably carried out for any desired real and / or ideal Yarn by entering the desired red-green-blue values so that free definable and selectable colors are available.

    Natürlich besteht die Möglichkeit, Meßparameter, gemessene Garndurchmesser, statistische Auswertung, berechnete Realgewebe, frei definierte Bindungen, Parameter der Webmaschine etc. in einer Datenbank zu speichern und im Bedarfsfall wieder abzurufen. Of course there is the possibility of measuring parameters, measured yarn diameters, statistical evaluation, calculated real tissue, freely defined bindings, parameters save the weaving machine etc. in a database and if necessary retrieve again.
