Abstract

A contactless diameter measuring device continuously measures the core dia. and stores the result in a store. A second dia. measuring device measures the total dia. including twice the insulation or sheath thickness. Test results from the first device pass through the store at the same speed as the wire passes throught eh extruder, so that two correct test values are compared. The difference between the two diameters is the measure for the insulation thickness.

Description

Es ist die Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung zu schaffen, das geeignet ist, die Isolations- oder Mantelwandstärke bei der Herstellung von Einzeladern oder Kabeln in Extruderlinien laufend zu messen und ggf. die Wandstärke selbsttätig zu regeln.It is the object of the invention to provide a method and an apparatus to create that is suitable for the insulation or jacket wall thickness during manufacture to continuously measure single wires or cables in extruder lines and, if necessary, the wall thickness to regulate automatically.

Beschreibung: Unmittelbar vor Einlauf in den Extruder ( 1) mißt das Durchmesserprüfgerät I, bestehend aus Lichtquelle (2) Kamera (3) und Anzeigeeinheit (4) laufend den Kernduchmesser (5) des zu ummantelnden Kaels und leitet die Ergebnisse in einen Speicher (6). Dieser Speicher besteht aus 12 parallelen Schieberegistern, deren Taktimpulsfrequenz der Anlagengeschwindigkeit (7) proportional ist. Während sich das Kabel von der Meßeinrichtung I ( 2), (3), (4) durch den Extruder (1) zu einem weiteren Durchmesserprüfgerät II, bestehend aus Lichtquelle (8), Kamera (9) und Anzeigeeinheit (10) bewegt, wandern die Meßergebnisse (4) mit gleicher 5eschwindigkeit durch den Speicher (6).Description: This is measured immediately before entering the extruder (1) Diameter testing device I, consisting of a light source (2), camera (3) and display unit (4) continuously the core diameter (5) of the keel to be coated and directs the results in a memory (6). This memory consists of 12 parallel shift registers, whose clock pulse frequency is proportional to the system speed (7). While the cable from the measuring device I (2), (3), (4) through the extruder (1) Another diameter testing device II, consisting of a light source (8), camera (9) and the display unit (10) moves, the measurement results (4) travel at the same speed through the memory (6).

Erreicht der vormals ausgemessene Kern (5) des inzwischen ummantelten Kabels den Durchmesserpunkt II (11), dann hat auch das dazugehörige Meßergebnis I des Kernes den Speicher durchlaufen. Die Differenz der beiden Meßwerte aus I und II ist gleich der Durchmesserzunahme bedingt durch die Ummantelung, also gleich der doppelten Mantelwandstärke.If the previously measured core (5) reaches the now encased Cable has the diameter point II (11), then also has the corresponding measurement result I traverse the core's memory. The difference between the two measured values from I and II is equal to the increase in diameter due to the sheathing, i.e. the same twice the jacket wall thickness.

Nach einer Signalaufbereitung erscheint der Meßwert für die Isolationswandstärke in Form von Sieben-Segment-Ziffern im Anzeigegerät (12) und extern im Bedienungspult.After signal processing, the measured value for the insulation wall thickness appears in the form of seven-segment digits in the display device (12) and externally in the control panel.

Wegen des Vergleichs der jeweils zueinander gehörenden Durchmesserwerte, eignet sich da I S 0 W A N D auch zur Messung der Isolationswandstärke bei Rundleitungen und Sektorleitungen und ohne Zusatzeinrichtungen auch bei Isolationswandstärkenmessung bei vordrallierten Sektoren.Because of the comparison of the respective diameter values belonging to one another, I S 0 W A N D is also suitable for measuring the insulation wall thickness of round cables and sector lines and without additional equipment, even with insulation wall thickness measurement in pre-swirled sectors.
