Description
Einrichtung zur Überwachung rotierender Spinntöpfe auf Fadenbruch Die in der Elektrotechnik benötigten Drähte aus leitendem Werkstoff werden vielfach mit Seide, Baumwolle oder Papier umsponnen. Dieses Spinnverfahren geht mitunter mit hoher Geschwindigkeit vor sich. Tritt hierbei ein Fadenbruch auf, so ergibt sich, insbesondere bei gleichzeitiger mehrlagiger Umspinnung, ein zeitraubender Arbeitsgang, wenn die Störung nicht sofort erkannt wird. Häufig müssen in solchen Fällen sogar größere Drahtmengen ausgemerzt werden, wenn die Isolierung ungenügend geworden ist. Device for monitoring rotating spinning pots for thread breakage The wires made of conductive material required in electrical engineering are often used wound with silk, cotton or paper. This spinning process sometimes works in front of you at high speed. If a thread break occurs here, the result is especially with simultaneous multi-layer wrapping, a time-consuming one Operation if the fault is not recognized immediately. Often need in such In cases where the insulation is inadequate, even larger amounts of wire can be eliminated has become.
Aus diesem Grunde ist es von großer Bedeutung, eine Einrichtung vorzusehen, die einen Fadenbruch sofort erkennen läßt und bei einem solchen so schnell wie möglich die Maschine stillsetzt. Zu diesem Zweck waren bereits Einrichtungen bekannt, bei denen die mit dem Spinner konzentrisch umlaufende Fadenspule durch den Fadenzug gegenüber dem Spinner eine zusätzliche Drehung erhält. Bei diesen Einrichtungen wird ein mechanischer Kontakt betätigt, wenn ein Fadenbruch eintritt. For this reason it is of great importance to provide a facility which allows a thread break to be recognized immediately and as soon as possible in the event of a thread breakage the machine stops. For this purpose facilities were already known at which the thread bobbin rotating concentrically with the spinner through the thread train receives an additional twist compared to the spinner. At these institutions a mechanical contact is activated when a thread break occurs.
Die Erfindung nutzt ebenfalls die vorerwähnte, der Fadenspule erteilte Drehung aus. Um aber Störungen, die bei der Verwendung mechanischer Kontakte unvermeidbar sind, zu vermeiden, wird gemäß der Erfindung die Einrichtung so ausgebildet, daß mit der Fadenspule, deren Drehzahl von der Drehzahl des Spinners abweicht, ein Element starr verbunden ist das mit einem auf dem Spinner angeordneten Element kontaktlos derart zusammenwirkt, daß bei Stillstand der Fadenspule relativ zum Spinner der Stromkreis des Antriebsmotors unterbrochen wird. The invention also makes use of the aforesaid given to the thread spool Rotation off. But to avoid disturbances that are unavoidable when using mechanical contacts are to be avoided, the device is designed according to the invention so that with the thread bobbin, the speed of which differs from the speed of the spinner, an element this is rigidly connected to an element arranged on the spinner without contact cooperates in such a way that when the bobbin is at a standstill relative to the spinner Circuit of the drive motor is interrupted.
Ein bevorzugtes Ausführungsbeispiel des Gegenstandes der Erfindung besteht darin, daß mit der Fadenspule ein Zahnrad aus magnetischem Werkstoff gekuppelt wird, dem ein auf dem Spinner angebrachtes elektromagnetisches System gegenübersteht, in dem nach Art der Zahnradsirene eine Tonfrequenz erzeugt wird. Diese Tonfrequenz wird nach Gleichrichtung über Schleifringe einem Verstärker zugeführt und dient zur Erregung eines Hilfsrelais. A preferred embodiment of the subject matter of the invention consists in that a gear made of magnetic material is coupled to the filament spool facing an electromagnetic system mounted on the spinner, in which a sound frequency is generated in the manner of a gear siren. This tone frequency is fed to an amplifier after rectification via slip rings and is used for exciting an auxiliary relay.
Bei Fadenbruch verringert sich die Umlaufzahl der Spule und nimmt praktisch in einer vernachlässigbar kleinen Zeit die Umlaufzahl des Spinners an. Dadurch bleibt die tonfrequente Spannung aus, das Relais wird stromlos und bewirkt, daß die Maschine stillgesetzt wird. If the thread breaks, the number of revolutions of the bobbin decreases and increases practically in a negligibly small time the number of revolutions of the spinner. As a result, the audio-frequency voltage remains off, the relay is de-energized and causes that the machine is stopped.
Die Abbildung veranschaulicht ein Ausführungsbeispiel des Gegenstandes der Erfindung. Das Zahnrad Z aus magnetischem Werkstoff ist an der nicht dargestellten Fadenspule starr befestigt. Diesem Zahnrad Z steht ein Permanentmagnetsystem P gegenüber, das auf dem ebenfalls nicht dargestellten Spinnteller angeordnet ist. Bei einer Drehzahldifferenz zwischen der Faden spule und dem Spinnteller, d. h. also zwischen dem Zahnrad Z und dem PermanentmagnetsystemP, entstehen in den Spulen Sp Wechselströme, die im allgemeinen im Tonfreqenzbereich liegen. Diese Wechselströme werden mit dem Gleichrichter G gleichgerichtet und über den Verstärker V dem Relais R zugeführt, das den Stromkreis des Antriebsmotors M schaltet. Bei Ausbleiben der Wechselspannung infolge angenähert gleicher Drehzahl des Zahnrades Z und des Dauermagneten P öffnet das Relais R den Kontakt K, wodurch der Motor M abgeschaltet wird. The figure illustrates an embodiment of the object the invention. The gear Z made of magnetic material is on the not shown Filament spool rigidly attached. This gear Z is a permanent magnet system P opposite, which is arranged on the spinning plate, also not shown. At a Speed difference between the thread bobbin and the spinning plate, d. H. so between the gear Z and the permanent magnet system P, alternating currents arise in the coils Sp, which are generally in the Tonfreqenzbereich. These alternating currents are with the Rectifier G rectified and fed to relay R via amplifier V, that switches the circuit of the drive motor M. If there is no AC voltage due to approximately the same speed of the gear Z and the permanent magnet P opens the relay R the contact K, whereby the motor M is switched off.
In dem Ausführungsbeispiel ist ein elektromagnetischer Frequenzerzeuger dargestellt. Selbstverständlich können auch elektrostatische oder lichtelektrische Generatoren, die an sich bekannt sind, für den neuen Zweck eingesetzt werden. In the exemplary embodiment is an electromagnetic frequency generator shown. Of course, electrostatic or photoelectric Generators, which are known per se, can be used for the new purpose.
