It identifies the relief profile of the pattern to give the repeat length through repetitive characteristics (16) together with the fabric movement speed. Also claimed is an operation where the gap (A) between a marked relief section (16) of a pattern (11) and the same marked relief section (16) of the next pattern (11), along the line (2) of fabric (1) travel, is measured by the optical yarn counter (12) in relation to the fabric (1) travel speed.

Description

Die Erfindung betrifft eine Einrichtung bzw. ein Verfahren gemäß Oberbegriff der unabhängigen Ansprüche. Dabei geht es um das Messen der Rapportlänge eines flachreliefartigen Musters einer kontinuierlich weiterbewegten textilen Stoffbahn, insbesondere in einem Spannrahmen oder dergleichen Maschine zum Trocknen und/oder Fixieren einer Stoffbahn.The invention relates to a device or a method according to Preamble of the independent claims. It's about measuring the repeat length of a bas relief pattern a continuously moving textile web, in particular in a stenter or similar machine for Drying and / or fixing a fabric web.

Spannrahmen sind Textilmaschinen, in denen eine Stoffbahn gehalten an den Längsrändern, kontinuierlich weitertransportiert und von oben und/oder von unten aus einer Vielzahl von Düsen mit Luft, bevorzugt mit erhitzter Luft, beaufschlagt wird. Dabei kann die Stoffbahn getrocknet und/oder in ihrer Farbe oder Form fixiert werden. In den meisten Spannrahmen wird die Stoffbahn an den Längskanten auf Nadeln gehalten, die mit Hilfe von Ketten kontinuierlich durch den Behandlungsraum der Maschine laufen. Je nachdem, ob die Stoffbahn beim Festlegen auf den Nadeln, also beim Einnadeln, schneller oder langsamer als die Kette läuft spricht man von einem Einnadeln mit Vor- oder Nacheilung. - Es gibt auch Spannrahmen mit anderen Haltemitteln als Nadeln, z.B. mit Klemm-Mitteln, sogenannte Kluppen. Die vorliegende Erfindung betrifft alle diese Haltemittel, lediglich der einfacheren Beschreibung wegen wird zum Teil nur von einem Einnadeln gesprochen.Tenter frames are textile machines in which a fabric web is held on the longitudinal edges, continuously transported and from above and / or from below a plurality of nozzles air, preferably heated air, is applied. Here the fabric can be dried and / or in its color or Shape to be fixed. In most stenter frames the Fabric web held on the longitudinal edges on needles with the help of chains continuously through the treatment room of the machine to run. Depending on whether the fabric when setting on the needles, i.e. when needling, faster or slower than the chain runs one speaks of a needling with pre or Pursuit. - There are also stenter frames with other holding devices as needles, e.g. with clamping means, so-called clips. The present invention relates to all of these retention means, only for the sake of simpler description, in part only spoken of a needling.

Wenn eine Stoffbahn, beispielsweise ein Gardinenstoff oder eine Stickerei, behandelt werden soll, die ein Muster mit einem Rapport aufweist, ist im allgemeinen darauf zu achten, daß eine vorgegebene Rapportlänge während der gesamten Behandlung möglichst exakt eingehalten wird. Die Länge des Rapports soll im allgemeinen nicht nur beim Anlaufen der Maschine bzw. beim Einfädeln der Stoffbahn, sondern auch während des Betriebs überwacht werden. Wenn die gemessene Rapportlänge nicht den vom Fabrikanten vorgegebenen Wert hat, soll die Einführung - auf dem Spannrahmen, z.B. das Aufnadeln der Bahn - mit entsprechender Vor- oder Nacheilung erfolgen.If a fabric, for example a curtain fabric or Embroidery that is to be treated using a pattern with a In general, it is important to ensure that a repeat predefined repeat length during the entire treatment is adhered to as precisely as possible. The length of the repeat should be generally not only when starting the machine or when Threading the fabric, but also during operation be monitored. If the measured repeat length does not match the value specified by the manufacturer, the introduction - on the stenter, e.g. the needling of the web - with appropriate Pre- or post-hurry.

Zumindest in den Fällen, in denen die Rapportlänge des flachreliefartigen Musters in der beschriebenen Weise zu überwachen ist, erfolgen diese Kontrollen und die entsprechenden Regelungen bisher unmittelbar durch das Maschinenpersonal, also durch manuelle Messung der Rapportlänge mit dem Metermaß und durch manuelle Nachstellung der Maschine.At least in the cases where the repeat length of the bas-relief Monitor patterns in the manner described these controls and the corresponding regulations are carried out hitherto directly by the machine personnel, i.e. by manual measurement of the repeat length with the meter and through manual adjustment of the machine.

Es gibt im Handel optische Fadenzähler, die unter anderem dazu dienen, Fäden einer gewebten Stoffbahn oder Maschen eines Gewirkes zu zählen. Die Geräte zählen jeden einzelnen Faden einer vorbeilaufenden Stoffbahn und zeigen die Fadendichte an. Durch Anpassung der Längsspannung läßt sich auf diese Weise eine Stoffbahn vorgegebener Fadendichte erzeugen.There are optical thread counters in the trade, among other things serve, threads of a woven fabric or stitches of a knitted fabric to count. The devices count every single thread passing fabric and show the thread density. By adjusting the longitudinal tension can be in this way generate a fabric web of predetermined thread density.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum berührungslosen Messen der Rapportlänge eines flachreliefartigen Musters bei laufender Warenbahn zu schaffen, die es ermöglicht, plastische Muster, wie Wirkereien oder Stickereien in einem Gardinenstoff, rapportmäßig zu erfassen und dadurch die manuelle Messung mit Metermaß zu ersetzen.The invention has for its object a device for non-contact measurement of the repeat length of a bas-relief type Creating patterns while the web is running, which enables plastic patterns, such as knitting or embroidery in a curtain fabric, to be reported and thus the to replace manual measurement with meter measure.

Die erfindungsgemäße Lösung wird in den Kennzeichen der unabhängigen Ansprüche angegeben. Verbesserungen und weitere Ausgestaltungen der Erfindung werden in den Unteransprüchen angegeben. In den Ansprüchen und in dieser Beschreibung wird oft nur kurz von einem Fadenzähler auch dann gesprochen, wenn zugleich ähnlich arbeitende Geräte, wie Nahtmelder, gemeint sind. Das geschieht gegebenenfalls der Vereinfachung halber. The solution according to the invention is in the characteristics of the independent Claims specified. Improvements and further refinements the invention are specified in the subclaims. In the claims and in this description is often only spoken briefly of a thread counter even if at the same time similar devices, such as seam detectors, are meant are. This is done for the sake of simplicity.

In der Regel umfaßt der Begriff "optischer Fadenzähler" im vorliegenden Zusammenhang alle Geräte, die ähnlich wie der Fadenzähler in der Lage sind, auf Stoffbahnen Reliefprofile zu erkennen und zu unterscheiden.As a rule, the term "optical thread counter" in the present context all devices similar to the thread counter are able to create relief profiles on fabric panels recognize and distinguish.

Grundsätzlich wird erfindungsgemäß bei einer Einrichtung eingangs genannter Art zum Messen der Rapportlänge der Stoffbahn ein optischer Fadenzähler zugeordnet, welcher das Reliefprofil des zu erfassenden Musters erkennt und dergestalt ausgewertet, daß der anhand von charakteristischen wiederkehrenden Merkmalen dieses Reliefprofils unter Einbeziehung der Bahntransportgeschwindigkeit die Rapportlänge ermitteln kann. Die charakteristischen, wiederkehrenden Merkmale des Reliefprofils können auch mit dem Begriff "Rhythmus" des Reliefprofils umschrieben werden.Basically, according to the invention, the beginning of a device mentioned type for measuring the repeat length of the fabric an optical thread counter assigned to the relief profile recognizes the pattern to be recorded and evaluates it in this way, that based on characteristic recurring features this relief profile including the rail transport speed can determine the repeat length. The characteristic recurring features of the relief profile also described with the term "rhythm" of the relief profile will.

Durch die Erfindung wird erreicht, daß ein Oberflächenprofil mit Hilfe eines optischen Fadenzählers oder dergleichen Tastgerät berührungslos auszumessen und dabei die Rapportlänge zu erkennen ist. Hierzu genügt - wie gesagt - im Prinzip ein Meßgerät, das im Prinzip wie ein optischer Fadenzähler arbeitet, also insbesondere die vorbeilaufende Bahn auf einer Linie (in Transportrichtung) abtastet.It is achieved by the invention that a surface profile with the help of an optical thread counter or similar touch device measure contactlessly and increase the repeat length is recognizable. As already mentioned, a measuring device is sufficient for this, which basically works like an optical thread counter, in particular the passing train on a line (in Direction of transport).

Die Erfindung sieht die Verwendung mindestens eines optischen Fadenzählers zum berührungslosen Messen der Rapportlänge einer Stoffbahn. In den Fadenzähler soll der Rapport des zu prüfenden Reliefs längs der Stoffbahn in Transportrichtung einzuprogrammieren und mit der gemessenen Wirklichkeit zu vergleichen sein. Der Fadenzähler soll den Rhythmus des Reliefprofils unter Einbeziehung der Warentransportgeschwindigkeit erfassen, das heißt die Wiederkehr wenigstens einer Reliefspitze (also einer prägnanten Höhe oder Tiefe im Muster) der vorbeilaufenden Stoffbahn wiedererkennen können. Alternativ oder zusätzlich kann auch ein Mittelwert von Reliefhöhen eines Rapports gemessen, programmiert und mit dem Fadenzähler wiedererkannt werden. The invention provides the use of at least one optical Thread counter for non-contact measurement of the repeat length of one Fabric panel. The repeat of the item to be checked should be in the thread counter Programming reliefs along the fabric in the direction of transport and compare it with the measured reality be. The thread counter is supposed to underline the rhythm of the relief profile Include the speed of goods transport, that is, the return of at least one relief peak (i.e. a concise height or depth in the pattern) of the passing Recognize the fabric. Alternatively or additionally can also be an average of relief heights of a repeat measured, programmed and recognized with the thread counter will.

In einer einfachsten Ausbildung der erfindungsgemäßen Einrichtung wird die von dem Fadenzähler erfaßte Rapportlänge angezeigt. Der Maschinenführer kann dann die Maschine so nachstellen, daß eine vorgegebene Rapportlänge erhalten wird. In einer weiteren Ausgestaltung der Einrichtung werden die Meßergebnisse des Fadenzählers unmittelbar der Maschinenregelung vorgegeben, so daß die Rapportlänge automatisch auf den vom Fabrikanten gewünschten Wert eingestellt wird. In a simplest embodiment of the device according to the invention the repeat length recorded by the thread counter is displayed. The machine operator can then adjust the machine that a predetermined repeat length is obtained. In a Further design of the device are the measurement results the thread counter is given directly to the machine control, so that the repeat length automatically matches that of the manufacturer desired value is set.

Anhand der schematischen Darstellung eines Ausführungsbeispiels werden Einzelheiten der Erfindung erläutert.Based on the schematic representation of an embodiment details of the invention are explained.

In der beiliegenden Figur wird die Draufsicht auf einen FlachSpannrahmen im Prinzip gezeigt. Eine Stoffbahn 1 wird in Transportrichtung 2 bewegt. Die Stoffbahnlängsränder 3 und 4 werden, z.B. in Nadeln 5, von Spannrahmenketten 6 so gehalten, daß die Stoffbahn in der Querrichtung 7 gespannt ist. Die Ketten 6 laufen endlos über Kettenräder 8, denen je ein Antrieb 9 zugeordnet wird. Die Stoffbahn 1 wird den Nadeln 5 der Ketten 6 über eine Zuführwalze 10 vorgelegt und im Anschluß an die Zuführwalze 10, z.B. mit Hilfe von (nicht gezeichneten) Aufnadelrädern, auf die Nadeln 5 aufgenadelt.The attached figure shows the top view of a flat clamping frame shown in principle. A fabric 1 is in Transport direction 2 moves. Longitudinal fabric edges 3 and 4 e.g. in needles 5, held by stenter chains 6 so that the fabric is stretched in the transverse direction 7. The chains 6 run endlessly over sprockets 8, each of which has a drive 9 is assigned. The fabric 1 becomes the needles 5 of the chains 6 submitted via a feed roller 10 and following the Feed roller 10, e.g. with the help of pinwheels (not shown), needled onto the needles 5.

Erfindungsgemäß wird einem zu prüfenden Stoffbahn-Reliefmuster mit Rapporten 11 ein optischer Fadenzähler 12 zugeordnet, der über einen Lichtstrahl 13 und einen Reflexstrahl 14 die charakteristischen Merkmale bzw. den Rhythmus des Rapports 11 längs einer Linie 15 der Stoffbahn 1 mißt. Wenn der Fadenzähler 12 die Wiederkehr einer, zu jedem der Rapporte 11 gehörenden, bestimmten Profilspitze 16 wiedererkennen kann, läßt sich der Abstand A von Profilspitze zu Profilspitze 16 erfassen und damit die Rapportlänge L messen.According to the invention, a fabric relief pattern to be tested is used with repeats 11 assigned an optical thread counter 12, the the characteristic via a light beam 13 and a reflection beam 14 Characteristics and rhythm of the repeat 11 measures along a line 15 of the fabric web 1. If the thread counter 12 the return of one belonging to each of the reports 11 can recognize certain profile tip 16, can the distance A from profile tip to profile tip 16 and measure the repeat length L.

Die Werte A und L, die gleich groß sind, können dem Maschinenführer optisch angezeigt werden. Zeigt der Fadenzähler 12 eine "falsche" Rapportlänge an, so soll korrigierend eingegriffen werden. Der Maschinenführer soll die Voreilung oder die Geschwindigkeit der am Stoffbahnrand 3 angreifenden Ketten 6 ändern, bis die vorgegebene Rapportlänge L erreicht ist.The values A and L, which are the same size, can be used by the machine operator be visually displayed. The thread counter 12 shows one "Incorrect" repeat length on, so corrective action should be taken will. The machine operator should lead or Speed of the chains 6 attacking the fabric edge 3 change until the specified repeat length L is reached.

Es liegt aber auch im Rahmen der Erfindung, daß nicht nur die Messung, sondern auch die Einstellung der Rapportlänge 9 automatisch erfolgt. In diesem Fall werden die Meßergebnisse des optischen Fadenzählers 12 beispielsweise einem Vergleicher 19 über eine Leitung 20 zugeführt. Der Vergleicher 19 kann, wenn sich eine Norm-Abweichung der Meßergebnisse des optischen Fadenzählers 12 ergibt, die Differenzgeschwindigkeit zwischen Zuführwalze 10 und Ketten 6, z.B. über Leitungen 22, 23 so verstellen, daß die Rapportlänge schließlich exakt den gewünschten Wert erhält.But it is also within the scope of the invention that not only Measurement, but also the setting of the repeat length 9 automatically he follows. In this case, the measurement results of the optical thread counter 12, for example a comparator 19 supplied via a line 20. The comparator 19 can if there is a standard deviation of the measurement results of the optical thread counter 12 gives the difference in speed between Feed roller 10 and chains 6, e.g. over lines 22, 23 so adjust that the repeat length finally exactly the desired Receives value.
