Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Überwachung eines Effektgarnes entsprechend dem Oberbegriff des Patentanspruchs.The invention relates to a device for monitoring an effect yarn according to the Generic term of the claim.

Der Anmelderin ist aus der Praxis eine derartige Vorrichtung zur Überwachung eines mehrfädigen Effektgarnes bekannt, das mittels einer Hohlspindel verzwirnt wird, nachdem jede Komponente des Effektgarnes getrennt und unabhängig vom anderen Komponentfaden überwacht wird. Zu diesem Zweck sind auf der Laufbahn jedes dieser Fäden Einrichtungen montiert, die z. B. auf die Zugverminderung des Materials, Materialmangel oder auf ein Zerreißen des Materials anssprechen. Hierbei ist jedoch eine direkte Überwachung des Weges des sich von der Hohlspindel frei abwickelnden Befestigungsfadens schwierig. Es ist daher eine komplizierte und teure Automatik notwendig, die trotz allen Aufwandes keine zufriedenstellenden Ergebnisse zeitigt. From practice, the applicant is such a device for monitoring a multi-thread fancy yarn known, which is twisted by means of a hollow spindle after each component of the fancy yarn has been separated and is monitored independently of the other component thread. To this end are on the runway each of these threads mounted devices which, for. B. on the tension reduction of the material, lack of material or respond to the material tearing. However, direct monitoring of the Difficulty way of the fastening thread unwinding freely from the hollow spindle. It is therefore a complicated one and expensive automation is necessary, which despite all the effort does not produce satisfactory results.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorichtung der beschriebenen Art anzugeben, mit der die Materialzufuhr unterbrochen wird, wenn der sich von der Hohlspindel abwickelnde Befestigungsfaden reißtThe invention has for its object to provide a device of the type described with which the Material feed is interrupted when the unwinding fastening thread from the hollow spindle breaks

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs gelöst According to the invention, this object is achieved by the characterizing features of the patent claim

Die Schlingen des Effektgarnes werden beim Reißen des Befestigungsfadens von einem vor dem Fadenführer angeordneten Häkchen aufgehalten. Unmittelbar vor dem Fadenführer liegt das Kontakt-Tensometer, dessen Abtastarm einen Druck auf das fertige Effektgarn ausübt. The loops of the fancy yarn are held in front of the thread guide when the fastening thread breaks arranged checkmarks held up. Immediately in front of the thread guide is the contact tensometer, whose Sensing arm exerts pressure on the finished fancy yarn.

Die Erfindung wird anhand der Zeichnung näher erläutert. Diese zeigt eine schematische Darstellung einer erfindungsgemäßen Vorrichtung.The invention is explained in more detail with reference to the drawing. This shows a schematic representation of a device according to the invention.

Beim Zerreißen des Befestigungsfadens 6 bildet der Effektfaden 1, der zusammen mit den Grundfaden 2 durch den Fadenführer 3 und ein gegeneinander drükkendes Walzenpaar 4 hindurchläuft, Schlingen, die größer als die normalerweise gebildeten Schlingen sind. Einige dieser Schlingen verhaken sich in dem Häkchen 9, wodurch das Aufwickeln des fertigen Effektgarnes 8 auf die Spule 13 eingestellt wird. Mittels der Andrückwalzen 7 wird die Zufuhr des Grundfadens 2 und des Effektfadens 1 fortgesetzt, so daß in dem von diesen begrenzten Bereich und dem Fadenführer 10 eine Spannungsverminderung auftritt. Der Abtastarm 11 des Kontakt-Tensometers 12 wird ausgelenkt, wodurch eine oder mehrere Arbeitsstellen der Maschine stillgesetztWhen the fastening thread 6 is torn, the effect thread 1, which together with the base thread 2 runs through the thread guide 3 and a pair of rollers 4 pressing against one another, loops that are larger than are the normally formed loops. Some of these loops get caught in the hook 9, whereby the winding of the finished fancy yarn 8 on the bobbin 13 is stopped. By means of the pressure rollers 7, the supply of the base thread 2 and the effect thread 1 is continued, so that in that of these limited area and the thread guide 10 a reduction in tension occurs. The scanning arm 11 of the Contact tensometer 12 is deflected, whereby a or several workplaces on the machine are shut down

Patentanspruch:Claim: Vorrichtung zur Überwachung eines Effektgarnes durch einen Abtastarm (11) eines Kontakt-Tensometers (12), wobei die Schlingen des Effektgarnes mittels eines von einer Hohlspindel (5) abgezogenen Befestigungsfadens (6) befestigt werden, dadurch gekennzeichnet, daß der Abtastarm (11) des Kontakt-Tensometers (12) zur Abtastung des fertigen Effektgarnes hinter der Hohlspindel (5) in einer von Andrückwalzen (7) und einem Fadenführer (10) begrenzten Zone angeordnet ist, und daß vor dem Fadenführer (10) ein Häkchen (9) zum Eingreifen in die Schlingen des Effektgarnes beim Zerreißen des Befestigungsfadens (6) angeordnet istDevice for monitoring a fancy yarn using a scanning arm (11) of a contact tensometer (12), the loops of the fancy yarn being pulled off by means of a hollow spindle (5) Fastening thread (6) are attached, thereby characterized in that the scanning arm (11) of the contact tensometer (12) for scanning the finished Fancy yarn behind the hollow spindle (5) in one of pressure rollers (7) and a thread guide (10) limited zone is arranged, and that in front of the thread guide (10) a hook (9) to engage in the loops of the fancy yarn is arranged when the fastening thread (6) is torn werden. Dieser Vorgang wiederholt sich auch beim Zerreißen des Grundfadens.will. This process is repeated when the basic thread is torn. Das Häkchen 9 ist in einem Abstand von 0,05 mm vor dem Fadenführer 10 angeordnet Das Kontakt-Tensometer 12 befindet sich in der vom Fadenführer 10 und dem Walzenpaar 7 begrenzten Zone, wobei das Walzenpaar 7 hinter der Hohlspindel S angeordnet istThe hook 9 is arranged at a distance of 0.05 mm in front of the thread guide 10. The contact tensometer 12 is located in the zone delimited by the thread guide 10 and the pair of rollers 7, the pair of rollers 7 is arranged behind the hollow spindle S.
