Abstract

The spinning bobbin is mounted on a cylindrical inner-electrode for determining the capacity by means of a measuring bridge. The sleeve-shaped outer electrode is placed around the bobbin, and has a variable diameter. The arrangement pref. applies to core-formers for high-polymer, melt- or solution-spun yarns, according to the DK-method.

H. on bobbins melt or solution-spun threads of high polymers, according to dor DK-Methole.

B@im Aufwickelprozeß passieren die Fäden eine Befeuchtungseinrichtung, in der sie mit einem Feuchtefilm benetzt werden, um besondere, technologisch notwendige Verarbeitungseigenschaften zu erzielen.B @ in the winding process, the threads pass a moistening device, in which they are moistened with a film of moisture to produce special, technologically necessary To achieve processing properties.

Dieser Feuchteauftrag hängt von mehreren Parametern ab, wie Leispielsweise von der Abzugsgeschwindigkeit und dem Raumklima, so daß der Zustand der Spinnwickel laufend zerstörungsfrei iiberpriift werJen muß.This application of moisture depends on several parameters, such as, for example of the take-off speed and the room climate, so that the condition of the spinning package Must be continuously checked non-destructively.

Ändert sich der Feuchteauftrag durch außere Einflüsse in unkontrollierter Weise, ergeben sich lür die nachfolgenden Technologien Verarbeitungsschwierigkeiten und Qualitätsmängel.If the moisture application changes due to external influences in an uncontrolled manner In this way, processing difficulties arise for the following technologies and quality defects.

Es ist bekannt, die Überprüfung durch Probeentnahme und Trocknung vorzunehmen.It is known to check by sampling and drying to undertake.

Dieser Verfahren, den Feuchteverlust der Prebe bei der Trecknung festzustellen und auf den Zustand nach dem Spinnprozeß zu schließen, ist aufwendig und ergibt keine für den Feuchtegehalt des gesamten Wickelkörpers repräsentative Werte.This method to determine the moisture loss of the Prebe during the trek and to infer the state after the spinning process is complex and yields no values representative of the moisture content of the entire wound package.

Es ist bereits bekannt, den Feuchtegehalt von flüssigen eder festen Substanzen aufgrund des hohen Dielektrizitätswertes des wassers mittels DK-Messungen zu bestimmen.It is already known the moisture content of liquid or solid Substances due to the high dielectric value of the water by means of DK measurements to determine.

Fine z@rstörungsfreie und genaue Feuchtemessung an Probekörpern mit spezieller Geemetrie erfordert jedoch sperielle, dem Meßproblem angepaßte Kendensatorkonstruktionen.Fine, undisturbed and accurate moisture measurement on test specimens with Special Geemetrie requires special, the measuring problem adapted end sensor constructions.

Der Erfindung ltgt die Aufgabe zugrunde, eine Vorrichtung zu entwiekeln,mit der eine zerstörungsfreie Feuchtebestimmung in Spinnspulen nach der DK-Meßmethode durchgeführt werden kann. Dabei s@llen die Meßergebnisse bei unterschiedlichen Bewicklungsdurchmessern reproduzierbar sein.The invention is based on the object of developing a device with the non-destructive moisture determination in spinning bobbins according to the DK measuring method can be carried out. The measurement results should be obtained with different winding diameters be reproducible.

Erfindungsgemäß wird auf einer zylinderförmigen Innenelektrode die Spinnspuls aufgesetzt. Um den Wickelkörper wird eine manschettenförmige Anßenelektrode gelegt, die durch ihre besondere Form verschiedenen Außendurchmessern angepaßt werden kann.According to the invention, the Spin pulse applied. A sleeve-shaped face electrode is placed around the winding body placed, which can be adapted to different outer diameters due to their special shape can.

Mit einer Meßbrüche wird die Kapazität des aus Innenelektrode, Spinnspule als Dielektrikum und Außenelektrode bestehenden Kondensatoraufbaus bestimmt.The capacitance of the inner electrode, spinning bobbin intended as a dielectric and outer electrode existing capacitor structure.

Der Innenelektrode werden zylinderförmige Schutzelektroden zugeordnet. Dadurch wird eine Feldbomogenisierung erreicht und damit die wesentliche Voraussetzung für die Reproduzierarbeit der Meßergebnisse bei unterschiedlichen Bewicklungsdurchmessern geschaffen.Cylindrical protective electrodes are assigned to the inner electrode. This achieves a field homogenization and thus the essential prerequisite for reproducing the measurement results with different winding diameters created.

In das Meßergebnis gcht als wesentlicher Farameter der Feuohtegehalt des Wickelz ein.The essential farameter in the measurement result is the fire content of the wrap.

Die übrigen Parameter sind bekannt und können r@@hnerisch eliminiert werden.The other parameters are known and can be eliminated r @@ hnerisch will.

Mit dem Ergebnis kann sofort in die Steuerung der Befeuchtungsanlage der Aufwiokelmeschine nach technologischer Notwendigkeit eingegriffen werden. Damit ist die Voraussetzung für eine optimale Qualität die sich aus diesem Parameter begründet, gegeben.The result can be used immediately in the control of the humidification system the winder machine can be intervened according to technological necessity. In order to is the prerequisite for optimal quality based on this parameter, given.

Die Erfindung sell an einem Aasführungsbeispiel näher erläutert werden.The invention can be explained in more detail using an example.

Die zugehörige Zeichnung z@igt die erfindungsgemäße Vorrichtung schematisch dargestellt.The associated drawing shows the device according to the invention schematically shown.

Die Spinnspule 2 sitzt auf der Innenelektrode 1, der Schutzelektroden1 a zugeordnet sind, und wird von der Außenelektrode 3 umschlossen.The spinning bobbin 2 sits on the inner electrode 1, the protective electrodes 1 a, and is enclosed by the outer electrode 3.

Dieser Kendensatoraufbau liegt an einer C-Meßbrücke 4, die vom Generater 6 gespeist und deren Ausgangsspannung dem selektiven Verstärker 5 zugeführt wird.This Kendensatoraufbau is on a C-measuring bridge 4, from the generator 6 and the output voltage of which is fed to the selective amplifier 5.

Mittels des C-Abgleichs 4 a wird die Meßbrücke so abgeglichen, daß der Indikater 5 a ein Minimum zeigt.By means of the C adjustment 4 a, the measuring bridge is adjusted so that the indicator 5 a shows a minimum.

Der as C-Abgleich 4 a abgelesen. Wert entspricht dann der Kapazität des Spulenkondensators Mit dem Meßergebnis kann über ein Nemogramm der Feuchtegehalt der Spinnspule bestimmt werden.Read off the as C adjustment 4 a. The value then corresponds to the capacity of the coil capacitor With the measurement result, the moisture content can be determined via a nemogram the bobbin can be determined.
