Description
Die vorliegende Erfindung behandelt eine neue Anordnung zur Feststellung des Feuchtigkeitsgehaltes von aus Trocknungsvorrichtungen fortlaufend austretenden Stoffbahnen, z. B. Papierbahnen. Ein sicheres Erkennen des Feuchtigkeitsgehaltes ist für den Güteausfall der Stoffbahn von großem Wert und ermöglicht es allein, eine Trocknungsvorrichtung an der Höchstgrenze ihrer Wirtschaftlichkeit arbeiten zu lassen·. Die bekanntgewordenen Feuchtigkeitsmesser sind für den vorliegenden Zweck ungeeignet,· das gilt besonders von den Meßgeräten, die in der Trocknungsmaschine den Trocknungsgrad der Stoffbahn aus der Luftfeuchtigkeit im Trocknungsraum oder auf Grund der Abnahme der elektrischen Leitfähigkeit der Stoffbahn beim Übergang aus dem nassen in den trockenen Zustand angeben sollen. Der zweckmäßige -Einbau eines Luftfeuchtigkeitsmessers begegnet Schwierigkeiten, während das !elektrische Abtasten der Stoffbahn in der Maschine, abgesehen von der Kurzschlußgefahr, durch die große Luftfeuchtigkeit in unmittelbarer Nähe der Stoffbahn fehlerhaft bleiben muß.The present invention deals with a new arrangement for determining moisture content of continuously emerging from drying devices, z. B. paper webs. A sure recognition the moisture content is of great value for the quality of the fabric and Alone it allows a drying device to be at its maximum economic efficiency to let work ·. The moisture meters that have become known are unsuitable for the present purpose, this is particularly true of the measuring devices that measure the degree of dryness in the drying machine Length of fabric from the humidity in the drying room or due to the decrease the electrical conductivity of the fabric during the transition from wet to dry State should indicate. The practical installation of a humidity meter encounters difficulties while the electrical scanning of the fabric in the machine, apart from the risk of short circuits, due to the high humidity in the immediate vicinity Near the length of fabric must remain faulty.
Beim maschinellen Trocknen vom Stoffbahnen, sei es in Trocknungsmasdhioen, Trocknungskammern oder auf Trommeln, wird infolge der bei der Bewegung der Stoffbahn auftretenden Reibung 'eine statische elektrische Ladung erzeugt. Die Stärke der elektrostatischen Ladung ist dabei allein von dem Feuchtigkeitsgehalt der Stoffbahn abhängig. Auf dieser Erkenntnis beruht die vorliegende Erfindung, nach welcher zwecks Messung der erzeugten statischen Elektrizität geeignete Meßinstrumente, z. B. Elektrometer, in der Nähe der Stoffbahn angeordnet werden. When machine drying of the fabric, be it in drying mashes, Drying chambers, or on drums, is a consequence of the movement of the fabric occurring friction 'generates a static electrical charge. The strength of the electrostatic charge is solely dependent on the moisture content of the fabric. The present invention is based on this finding, in order to measure the static electricity generated suitable measuring instruments, e.g. B. electrometer, are arranged in the vicinity of the web of fabric.
In der Zeichnung ist eine Anordnung nach der Erfindung beispielsweise dargestellt. In der Abb. 1 ist 1 ein bekanntes Elektroskop mit der der Stoffbahn entgegengerichteten Aufnahmeelektrode, die an ihrem Ende Metallblättchen als Zeiger trägt; die seitlich angebrachten Elektroden erden das Gehäuse. Die Zeiger spielen über einer Gradeintet lung 2, die nach Maßgabe der ermittelten Erfahrungswerte in bekannter Weise die Bereiche Naß, Trocken und Übertrocken unterscheidet. Der Arm 3 dient zum Anbau des Elektrometers. Mit bekannten fernwirkenden Mitteln kann man den jeweiligen Zeigerstand nach einem beliebigen Ort hin anzeigen oder zum selbsttätigen Einregem der. Trocknungsvorrichtung verwenden. Andere Elektrometer, auch die aus der Radiotechnik bekannten, können sinngemäß, angewandt werden.In the drawing, an arrangement according to the invention is shown, for example. In In Fig. 1, 1 is a known electroscope with the one facing the web of material Pick-up electrode with metal flakes at its end as a pointer; the side attached electrodes earth the housing. The hands play over a graduation ment 2, the areas according to the determined empirical values in a known manner A distinction is made between wet, dry and excessively dry. The arm 3 is used to attach the electrometer. With known remote operators A means can be used to display the respective pointer position towards any location or for automatic energizing. Use drying device. Other electrometers, those known from radio technology can also be used accordingly.
Die Abb. 2 und 3 zeigen den Anbau des Elektrometers 1 an Trocknungsmaschinen. In der Abb. 2 tritt die Stoffbahn 6 fortlaufend aus einer Trocknungsmas chine 4 aus, nimmt ihren Weg über eine Trocknungstrommel S und gelangt dann zur Ablage. Ein Elektrometer 1 ist zwischen der Trocknungsmaschine 4 und der Trommel 5 und ein weiteres Elektrometer 1 hinter der Trommel 5 angeordnet. Der Leitungsdraht 7 erdet das Elektrometergehäuse. In der Abb. 3 ist 'ein Meßgerät 1 eine Strecke hinter den Stoffauslaß,' aus der Trocknungsmaschine 8 gesetzt. Der geeignete Anbau ist durch die Maschinenart bedingt und kann auch hinter den Nachbehandlungsvorrichtungen bzw. in der Nähe der Stoffbahnablage erfolgen.Figs. 2 and 3 show the attachment of the electrometer 1 to drying machines. In the Fig. 2, the web 6 occurs continuously from a Trocknungsma chine 4, takes their way over a drying drum S and then arrives at the tray. An electrometer 1 is between the drying machine 4 and the drum 5 and another Electrometer 1 arranged behind drum 5. The lead wire 7 grounds that Electrometer housing. In Fig. 3 is' a Measuring device 1 a distance behind the stock outlet, 'from the drying machine 8 set. The appropriate attachment depends on the type of machine and can also be installed behind the aftertreatment devices or in close to the fabric shelf.
