Abstract
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 as well as the associated one 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. These well-known CAD systems allow new fabrics to be modified by changing a variety of To develop parameters. However, the basis for the calculation in CAD systems are always "ideal" yarn, i.e. Yarns, their diameter, fineness, tear resistance is constant over the entire yarn.
Bei realen Garnen sind jedoch die Garndurchmesser und sonstige Garneigenschaften nicht, wie bei dem "idealen Garn", über die Garnlänge 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 yarn length. So show real yarns Thin spots, thick spots, nits etc., which naturally affect the appearance of the later "Real tissue" impact, but in the tissue development on the CAD system are not taken into account. This often results in the obtained real tissue does not correspond to the designer's idea.
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 yarn production to optimize.
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 to take into account the real values of the respective yarn when designing the fabric and at the same time an adaptation and / or change in the bond or everyone any intersection taking into account the visual appearance of every 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 by changing each Crossing to highlight thin, thick or nits or optically in the Let the background kick. In some fabrics the optical effects are which are achieved by irregular yarns, and by being freely definable the binding is made possible, if irregularities are desired underlined optically 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 individual Measure yarns optoelectronically. Due to the defined nature of the desired Tying becomes a taking into account the individual measured values of the yarn three-dimensional representation of the real tissue calculated and visualized. Any one Crossing can - preferably via a schematic representation of the tissue on a screen and input with the keyboard or a mouse - changed will. The real tissue can in turn be visualized and changed as long as 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 is no longer required is to turn on the loom to see what the real fabric looks like to then 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 the colors along a yarn and into the evaluation device to be transmitted so that, in addition to the real yarn diameters, the real colors can be taken into account when calculating the real fabric.
Die Erfindung wird nun anhand eines Ausführungsbeispiels näher erläutert:
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
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
Neben dem Meßkopf umfaßt das Meßgerät 12 eine Garnzuführung und Elektronik.In addition to the measuring head, the
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, for example, from BARCO / Belgium distributed.
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 the yarn diameter measurement is at least 1/100 mm. The measurement of the diameter of the yarn should be 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
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
Vorzugsweise ist die Bindungseingabevorrichtung 13 zusammen mit der Steuer- und
Auswertevorrichtung 14 in einem Computer integriert.Preferably, the
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
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 are taken into account and a masking calculation of the Threads is carried out. When visualizing, 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 must also be used to calculate the real fabric (Fabric size) entered and warp and weft threads assigned, so that the calculated real fabric actually corresponds to the result woven later 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, individual ones can now
