Beschreibung description
Bei einem bekannten Fadenwächter mit einer Luntensperrvorrichtung für ein Spinnmaschinen-Streckwerk (DE 3 336 215 C2) dient als gemeinsamer Halter eine sich längs der Oberwalzenreihe erstreckende, an der Spinnmaschine befestigte Tragschiene, in der auch das elektrische Kabel zwischen dem Fadenwächter und der Luntensperrvorrichtung verläuft. Durch diese zusätzliche Tragschiene ist der Freiraum zwischen benachbarten Oberwalzenreihen der Streckwerke eingeschränkt. In a known thread monitor with a sliver locking device for a spinning machine drafting system (DE 3 336 215 C2), a mounting rail, which extends along the upper roller row and is fastened to the spinning machine and serves as a common holder, in which the electrical cable between the thread monitor and the sliver locking device also runs. This additional support rail limits the space between adjacent rows of top rollers of the drafting systems.
Der Erfindung liegt die Aufgabe zugrunde, den Fadenwächter und seine Luntensperrvorrichtung platzsparend anzuordnen, um die Bedienungs- und Wartungsmöglichkeiten zu verbessern. The invention is based on the object of arranging the thread monitor and its ratchet locking device in a space-saving manner in order to improve the operating and maintenance options.
Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst. Der Fadenwächter und seine Luntensperrvorrichtung sind am vorhandenen Tragarm gemeinsam so befestigt, dass sie ungehindert arbeiten und auch die Bedien- und Wartungsfreiheit nicht einschränken. Die Verbindungskabel zwischen Fadenwächter und Luntensperrvorrichtung sind im Tragarm geführt. This object is solved by the features of claim 1. The thread monitor and its match lock device are jointly attached to the existing support arm in such a way that they work unhindered and do not restrict freedom from operation and maintenance. The connecting cables between the thread monitor and the ratchet locking device are routed in the support arm.
Die erfindungsgemässe Anordnung von Fadenwächter und Luntensperrvorrichtung gemeinsam am Tragarm ist eine sehr rationelle Befestigung und spart zusätzliche Tragschienen für die Luntensperrvorrichtung und den Fadenwächter ein; die Montagezeit an der Maschine wird reduziert. The arrangement according to the invention of the thread monitor and the ratchet locking device together on the support arm is a very efficient fastening and saves additional support rails for the ratchet locking device and the thread monitor; the assembly time on the machine is reduced.
Nach Anspruch 2 ist ein Adapter zwischen dem Fadenwächtergehäuse und dem Tragarm eingebaut, wodurch die Befestigung des Fadenwächters an unterschiedlichen Tragarmen erleichtert wird. According to claim 2, an adapter is installed between the thread monitor housing and the support arm, whereby the attachment of the thread monitor to different support arms is facilitated.
Ein Ausführungsbeispiel der Erfindung ist für die Befestigung an Tragarmen mit Doppeloberwalzen beschrieben. An embodiment of the invention is described for attachment to support arms with double top rollers.
Die Zeichnung zeigt die Seitenansicht eines Fadenwächters und einer Luntensperrvorrichtung an einem Tragarm. The drawing shows the side view of a thread monitor and a ratchet locking device on a support arm.
Der an einer maschinenfesten Stange 1 befestigte Tragarm 2 trägt eine Luntensperrvorrichtung 3, dies bei ihrer Schaltung durch ein Fadenbruchsignal die einlaufende Lunte 4 auf einem Tisch 5 vor der Eingangsunterwalze 6 mittels einer Stoppklappe 7 klemmt und die Eingangsoberwalze 8 etwas anhebt. Diese Stopplage wird vor dem Wiederanspinnen mittels eines Handhebels 9, durch den die Eingangsobenwalze 8 abgesenkt und die Lunte 4 freigegeben wird, wieder gelöst; die Lunte 4 wird vom Eingangswalzenpaar 6, 8 wieder transportiert. Die Arbeitslage ist in der Zeichnung dargestellt. Vor dem Eingangswalzenpaar 6, 8 ist ein Verdichter angeordnet. The support arm 2 fastened to a machine-fixed rod 1 carries a sliver locking device 3, which when it is switched by a thread break signal clamps the incoming fuse 4 on a table 5 in front of the input lower roller 6 by means of a stop flap 7 and slightly raises the input upper roller 8. This stop position is released again before re-spinning by means of a hand lever 9, by means of which the input top roller 8 is lowered and the fuse 4 is released; the fuse 4 is transported again by the pair of input rollers 6, 8. The working situation is shown in the drawing. A compressor is arranged in front of the pair of input rollers 6, 8.
Am Ende des Tragarmes 2 ist ein Fadenwächter 11 so befestigt, dass sein Sensorgehäuse 12 parallel zu dem aus dem Ausgangswalzenpaar 13, 14 zu einer nicht dargestellten Spindel laufenden Faden 15 angeordnet ist. Der Fadenwächter 11 gibt bei Fadenbruch das Signal, durch das die Stoppklappe 7 in der Luntensperrvorrichtung 3 aus ihrer Betriebslage in die Stopplage geschoben wird. At the end of the support arm 2, a thread monitor 11 is fastened in such a way that its sensor housing 12 is arranged parallel to the thread 15 running from the pair of output rollers 13, 14 to a spindle, not shown. When the thread breaks, the thread monitor 11 gives the signal by which the stop flap 7 in the ratchet locking device 3 is pushed out of its operating position into the stop position.
Zwischen dem Tragarm 2 und dem Fadenwächter 11 ist ein Adapter 16 zur Anpassung an unterschiedliche Tragarme 2 vorgesehen; ausserdem ist zwischen dem Tragarm 2 und dem Fadenwächter 11 noch Platz für die Halterung einer Putzwalze 17. Between the support arm 2 and the thread monitor 11, an adapter 16 is provided for adapting to different support arms 2; there is also space between the support arm 2 and the thread monitor 11 for holding a cleaning roller 17.
Der Sensor im Sensorgehäuse 12 besteht aus einem Geber und einem Empfänger für das Fadenüberwachungssignal. Der Überwachung können Ultraschallsensoren oder andere berührungslose Sensoren, wie optische und kapazitive Sensoren, dienen. The sensor in the sensor housing 12 consists of a transmitter and a receiver for the thread monitoring signal. Ultrasound sensors or other non-contact sensors such as optical and capacitive sensors can be used for monitoring.
