"Induktive Kanten- oder Mittenabtastuag für metallische Bahnen""Inductive edge or center scanning for metallic tracks"
i-'iir die Kauten- oder Mittcnabtastung metallischer Bahnen ist es bereits bekannt; induktiv wirkende Initiatoren zu verwenden. Die Initiatoren enthalten einen Oszillator, dessen elektromagnetisches. Feld an der aktiven Seite frei austreten kann.i-'iir the Kauten- or Mittcnabtastung metallic traces is already known; to use inductive initiators. The initiators contain an oscillator, its electromagnetic. Field can emerge freely on the active side.

Nähert man der aktiven Fläche ein Metallteil, so wird dem Feld Energie entzogen, was eine Araplitudenänderung des Oszillators zur Folge hat. Die Anordnung der Initiatoren erfolgt üblicherweise derart, daß die iJcßflücho (aktive Fläche) in einem Abstand parallel zur metallischen Bahn verläuft. Tritt nun aus irgendwelchen Gründen eine seitliche Verschiebung der Dahn ein, dann wird von der Bahn entweder mehr oder weniger Meßfläche des Initiators abgedeckt, so daß in Abhängigkeit des seitlichen Abstandes der Bahn sich die Ausgangsgröße des Initiators ändert. Die Ausgangsgröße, als Spannung oder Strom, wird zur Führung oder Korrektur der metallischen Bahn verwendet. Di· Ausgangsgröße des Initiators wird aber auch dadurch mit beeinflußt, daß der Abstand der Höh· zwischen Meßfläche des Initiators und der metallischen Bahn durch Flattern oder Durchhang der Bahn nicht konstant gehalten werden kann. Wie Versuche gezeigt haben, wird durch Ilöhenabstandsänderungen die Ausgangsgröße bis fast zum zweifachen Wert der seitlichen Verschiebung der Bahn beeinflußt, was sich natürlich nachteilig auf die Kanten- oder Mittenregelung der Bahn auswirkt.If a metal part is approached to the active surface, energy is withdrawn from the field, which results in a change in the araplitude of the Oscillator. The arrangement of the initiators usually takes place in such a way that the iJcßflücho (active Surface) runs parallel to the metallic track at a distance. Now, for some reason, kick a side Shifting the Dahn one, then either more or less measuring area of the initiator is covered by the web, so that depending on the lateral distance of the web, the output size of the initiator changes. The output size, as Voltage or current, is used to guide or correct the metallic path. Di · output variable of the initiator but is also influenced by the fact that the distance between the height between the measuring surface of the initiator and the metallic Web cannot be kept constant due to fluttering or sagging of the web. As tests have shown, is through I height distance changes the output size by almost twice The value of the lateral displacement of the web influences, which of course has a detrimental effect on the edge or center control the railway affects.
Die Erfindung hat sich daher die Aufgabe gestellt, eine induktive Kanten- oder Mittenregelung zu schaffen, bei dem IIöhenänderungen der metallischen Bahn auf die Ausgangsgröße dos Initiators nahezu unbeeinflußt bleiben. Diese Aufgabe wird erfindungsgomäß dadurch gelöst, daß die Meßfläche des Initiators und die metallische Bahn senkrocht oder annähernd senkrecht zueinander angeordnet sind.The invention has therefore set itself the task of creating an inductive edge or center control in which the height changes of the metallic path remain almost unaffected on the initial size of the initiator. This task will According to the invention, solved in that the measuring surface of the initiator and the metallic track creeps up or approximately vertically are arranged to each other.

In der Zeichnung ist ein Ausführungsbeiepiel der Erfindung näher erläutert.In the drawing is an exemplary embodiment of the invention explained in more detail.
Mit 1 ist die metallische Bahn bezeichnet, an der seitlich und senkrecht zur Bahn ein Initiator 2 angeordnet ist. Seine wirksame Meßfläche ist mit 3 bezeichnet. Wird beispielsweise die metallische Bahn 1 seitlich nach rechts oder links ausgelenkt ι so verkleinert bzw. vergrößert sich der Abstand der Bahn 1 zur Meßfläche 3 de« Initiators 2, so daß sich die Ausgangsgröße des Initiators 2 entsprechend ändert und die Änderung der Ausgangsgröße zur Korrektur der Bahn 1 herangezogen wird.The metallic track is designated by 1, on which an initiator 2 is arranged to the side and perpendicular to the track. His effective measuring area is denoted by 3. For example the metallic web 1 is deflected laterally to the right or left ι thus reduced or increased the distance between the web 1 to the measuring surface 3 de «initiator 2, so that the output variable of the initiator 2 changes accordingly and the change the output variable is used to correct web 1.
Kommt noch unerwünschterweise ein Flattern der Bahn oder ein Durchhang der Bahn hinzu, so bleiben diese Erscheinungen fast unbeeinflußt auf di· Ausgangsgröße des Initiators, weil keiiiQ oder nur eine kleine, unbedeutende Ausgangsgröße erzeugt wird. Durch die erfindungsgemäße senkrechte Anordnung dee Initiators zur metallischen Bahn ist es auf einfache Art und Weise gelungen, Ausgangsgrößen infolge von Höhenschwankungen der Metallbahn fast gänzlich zu unterdrücken, so daß im wesentlichen nur die seitliche Auslenkung der Bahn die Ausgangsgröße des Initiators beeinflußt.Is there still an undesirable flutter of the web or a If the web slack is added, these phenomena remain almost unaffected on the initial size of the initiator, because no or only a small, insignificant output is generated. Due to the vertical arrangement of the initiator according to the invention For the metallic track, it has been possible in a simple manner to find output variables as a result of fluctuations in the height of the metal track to suppress almost entirely, so that essentially only the lateral deflection of the web influences the output size of the initiator.
