Description
Vorrichtung zum Anzeigen von Fadenbrüehen und anderen Unregelmäßigkeiten an Textilmaschinen, insbesondere an Ringspinn- und Ringzwirnmaschinen (Fadenwächter) Device for displaying thread stocks and other irregularities on textile machines, in particular on ring spinning and ring twisting machines (thread monitor)
Die Erfindung betrifft eine Vorrichtung zum Anzeigen von Fadenbrüchen und anderen Unregelmäßigkeiten des Fadenlaufes an Textilmaschinen, insbesondere an Ringspinn- und Ringzwirnmaschinen. Solche Vorrichtungen werden kurz fadenwächter genannt. ~The invention relates to a device for indicating thread breaks and other irregularities in the thread run on textile machines, in particular on ring spinning and ring twisting machines. Such devices are called thread monitors for short. ~
Elektrisch arbeitende Vorrichtungen zu diesem Zwecke sind bekannt. Es ist z.B. vorgeschlagen worden, den Fadenführer als Fühlglied zu verwenden, wobei bei fehlender Fadenspannung der Fadenführer nach der Seite umkippt und einen elektrischen Eontakt bewirkt. Es ist auch bekannt, zusätzliche Falldrähte oder Fühler anzuordnen, die auf dem laufenden Faden aufliegen oder von diesem geführt werden.Electrically operating devices for this purpose are known. For example, it has been proposed to use the thread guide to be used as a feeler, if there is no thread tension the thread guide tips over to the side and creates an electrical contact. It is also known to have additional drop wires or to arrange sensors that lie on the running thread or be guided by it.
Ferner ist bekannt, den Ringläufer als Kontaktorgan zu verwenden. Diese Vorrichtungen haben jedoch durchwegs den Fachteil, daß sie den Zwirn- oder Spinnprozess nachteilig beeinflussen, und daß die Eontakte infolge Flugansammlung unsicher arbeiten.It is also known to use the ring traveler as a contact member. However, these devices consistently have the specialist part that they adversely affect the twisting or spinning process, and that the contacts are unsafe as a result of flight accumulation work.
Die Erfindung geht davon aus, daß der Faden, sofern er sich in Bewegung befindet, eine Fadenführung zu mechanischen Schwingungen anregt. Das Vorhandensein dieser Schwingungen ist also ein charakteristisches Merkmal für die Fadenbewegung. Von diesen Schwingungen kann also ein Signal abgeleitet werden, welches kontrolliert, ob sich der Faden in Bewegung befindetThe invention assumes that the thread, if it is in motion, a thread guide to mechanical Stimulates vibrations. The presence of these vibrations is therefore a characteristic feature of the thread movement. A signal can be derived from these vibrations, which checks whether the thread is in motion

oder aber stillsteht, bzw. gerissen ist. Dieses Signal kann zur Auslösung eines Schaltvorganges benützt werden, z.B. ein Kontrollzeichen betätigen, ein Antriebsorgan abstellen usw. Auf diese Weise wird die Überwachung der Maschine erleichtert oder automatisiert.or stands still, or is torn. This signal can can be used to initiate a switching process, e.g. actuate a control sign, switch off a drive unit, etc. In this way, the monitoring of the machine is facilitated or automated.
Die Zeichnung gibt eine söhematische Darstellung der Erfindung, wobei in diesem Falle die Schwingungen des Fadenführers die Induktivität einer Spule beeinflussen und die Auswertung des Signals elektronisch erfolgt.The drawing gives a söhematic representation of the invention, in this case, the oscillations of the thread guide influence the inductance of a coil and the evaluation of the signal is done electronically.

Der Fadenführer (1) ist nach hinten verlängert über den Befestigungspunkt (2) hinaus und taucht in eine Induktionsspule (3). Läuft nun ein Faden (4) durch die Öse (5) des Fadenführers, so beginnt das hintere Ende des Fadenführers (1) zu schwingen und verändert so die Induktivität der Induktionsspule (3). Diese Änderung wird durch einen Diskriminator (6) geprüft und betätigt eine Signallampe (7) in dem Sinne, daß die Lampe leuchtet, wenn' keine Schwingungen vorhanden sind, weil der Faden ruht oder gerissen ist. Die Lampe verlöscht, sobald der Faden durch die öse läuft und durch den Fadendurchlauf Schwingungen im Fadenführer (1) entstehen.The thread guide (1) is extended to the rear over the fastening point (2) and immersed in an induction coil (3). A thread (4) now runs through the eyelet (5) of the Thread guide, the rear end of the thread guide begins (1) to oscillate and thus changes the inductance of the induction coil (3). This change is checked by a discriminator (6) and activates a signal lamp (7) in the sense that the lamp lights up when there are no vibrations are present because the thread is dormant or broken. The lamp goes out as soon as the thread runs through the eyelet and vibrations occur in the thread guide (1) as the thread passes through.
Die Auswertung des Signals kann auch auf andere Weise erfolgen, z.B. optisch oder pneumatisch.The signal can also be evaluated in other ways, e.g. optically or pneumatically.
