Abstract

In order to be able to monitor the flow of the filling compound (12) for a longitudinally waterproof cable for gas bubbles (14), a capacitive proximity switch (21) is arranged in a filling tube (11) whose wall (22) is made of plastic. <IMAGE>

Description

Vorrichtung zur Uberwachunq einer viskosen FüllmasseDevice for monitoring a viscous filling compound

Die Erfindung bezieht sich auf eine Vorrichtung zur Überwachung eines Stromes einer viskosen Füllmasse (mindestens 1 x 10 .2 Poise) auf Gasbeimischungen.The invention relates to a device for monitoring a Stream of a viscous filler (at least 1 x 10 .2 poise) to gas admixtures.

In verschiedenen Fällen sind bei Fertigungsvorgängen Ströme von viskosen Medien zu überwachen, so z.B. beim Füllen von elektrischen und/oder optischen Kabeln mit einer Masse, die die Ausbreitung von in das Kabel eingedrungenem Wasser verhindern soll. Da es gerade bei dem erwähnten Beispiel auf eine vollständige Füllung ankommt, um in jedem Falle die Bildung von Kanälen zu vermeiden, längs denen sich eingedrungenes Wasser im Kabel ausbreiten kann, muß der Füllmassestrom auf eventuell beigemischte Gaseinschlüsse überwacht werden.In various cases, in manufacturing operations, currents are viscous Monitor media, e.g. when filling electrical and / or optical cables with a mass that will prevent the spread of water that has entered the cable target. Since a complete filling is important in the example mentioned, in order to avoid in any case the formation of channels along which something penetrated If water can spread in the cable, the filling compound flow must possibly be mixed in Gas inclusions are monitored.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß in einem aus Kunststoff bestehendem Förderrohr ein kapazitiver Näherungsschalter angeordnet ist. Dabei wird davon ausgegangen, daß die Anwesenheit von Gas in der Füllmasse deutlich erfaßbare Kapazitätsänderungen bedingt, die in dem Schalter zur Verstimmung eines RC-Schwingkreises führt. Hierbei genügt die Empfindlichkeit der Vorrichtung, um Gasbeimischungen von einigen Kubikzentimetern erfassen zu können.To solve this problem it is proposed according to the invention, that in a conveyor pipe made of plastic a capacitive proximity switch is arranged. It is assumed that the presence of gas in the Filling mass clearly detectable capacitance changes caused in the switch for Leads to detuning of an RC resonant circuit. The sensitivity of the is sufficient here Device to be able to detect gas admixtures of a few cubic centimeters.

Die Erfindung wird anhand eines in der Zeichnung dargestellten und nachfolgend beschriebenen Ausführungsbeispieles im einzelnen erläutert. In der Zeichnung zeigt : Fig. 1 einen senkrechten Schnitt durch einen Teil eines Förderrohres, Fig. 2 ein Schaltschema des kapazitiven Näherungsschalters.The invention is based on one shown in the drawing and the embodiment described below explained in detail. In the drawing shows: FIG. 1 a vertical section through part of a conveyor pipe, FIG. 2 a circuit diagram of the capacitive proximity switch.

In einem Förderrohr 11 wird Füllmasse 12 in Richtung des Pfeiles 13 transportiert. In der aus Kunststoff bestehenden Wand 15 des Förderrohres 11 ist eine metallische Führungsbuchse 22 zur Aufnahme eines kapazitiven Näherungsschalters 21 vorgesehen, dessen Schaltung in Fig. 2 dargestellt ist. Die Führungsbuchse stellt dabei die zweite Elektrode gegenüber der Elektrode des Schalters 21 dar.In a conveying pipe 11, filling compound 12 is displaced in the direction of arrow 13 transported. In the plastic wall 15 of the conveyor pipe 11 is a metallic guide bushing 22 for receiving a capacitive proximity switch 21 is provided, the circuit of which is shown in FIG. The guide bush represents represents the second electrode opposite the electrode of the switch 21.

Wenn in der Füllmasse 12 Gaseinschlüsse 14 vorhanden sind, verändert sich wegen der unterschiedlichen Dielektrizitätszahlen von Gasen und der Füllmasse ( f r Luft = 1, r Füllmasse = 1t4) die Kapazität, die eine Verstimmung eines RC-Schwingkreises bewirkt. Die entsprechende Spannung wird in einem Verstärker 23 verstärkt und die so gewonnene Meßspannung UNeB kann der weiteren Auswertung zugeführt werden.If gas inclusions 14 are present in the filling compound 12, changes because of the different dielectric constants of gases and the filling compound (for air = 1, r filling mass = 1t4) is the capacity that detuning an RC resonant circuit causes. The corresponding voltage is amplified in an amplifier 23 and the The measurement voltage UNeB obtained in this way can be fed to further evaluation.
