Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Zur Nassbehandlung (wie Färben, Waschen, Spülen) von strangförmigem Textilgut sind bereits verschiedene Vorrichtungen bekannt, die mittels Düsen Luft auf bzw. in den Strang blasen, um ihn zu öffnen und zu verlegen. Bei einer bekannten Vorrichtung dieser Art (FR-A-1 583 849) wird die im strangförmigen Textilgut durch Einblasen eines Luftstrahles erzeugte Luftblase durch zwei Walzen zurückgehalten, von denen die eine ortsfest angeordnet und die andere beweglich gelagert ist. Je nach der Grösse der Luftblase wird die beweglich gelagerte Walze mehr oder weniger ausgelenkt, betätigt hierbei eine Steuerschaltung und beeinflusst damit den in das Textilgut eingeblasenen Luftstrahl.Various devices are already known for wet treatment (such as dyeing, washing, rinsing) of strand-like textile material, which blow air onto or into the strand by means of nozzles in order to open and lay it. In a known device of this type (FR-A-1 583 849), the air bubble produced in the strand-like textile material by blowing in an air jet is retained by two rollers, one of which is arranged in a stationary manner and the other of which is movably mounted. Depending on the size of the air bubble, the movably mounted roller is more or less deflected, actuates a control circuit and thus influences the air jet blown into the textile material.

Der Betrieb einer solchen Ausführung ist jedoch nicht zufriedenstellend. Da die eine der beiden Walzen beweglich sein muss, um ihre Abtastfunktion zu erfüllen, können die beiden Walzen die gebildete Luftblase nicht unter allen betrieblichen Verhältnissen einwandfrei zurückhalten. Es kommt vielmehr vor, dass die Luftblase durch einen plötzlichen Druckluftstoss schlagartig eine solche Grösse annimmt und die bewegliche Walze hierdurch momentan so stark auslenkt, dass ein Teil der Luftblase zwischen den beiden Walzen hindurchschiesst. Ein Beheben dieser Störung macht dann u.U. ein kurzzeitiges Abschalten der Luftzufuhr erforderlich.However, the operation of such an embodiment is unsatisfactory. Since one of the two rollers has to be movable in order to fulfill its scanning function, the two rollers cannot properly hold back the air bubble formed under all operating conditions. Rather, it happens that the air bubble suddenly takes on such a size due to a sudden blast of compressed air and, as a result, momentarily deflects the movable roller so much that part of the air bubble shoots through between the two rollers. Correcting this malfunction may a brief shutdown of the air supply is required.

Es ist weiterhin eine Vorrichtung zur Nassbehandlung von strangförmigem Gut bekannt (FR-A-2 193 333), bei der vor den beiden zum Zurückhalten der Luftblase dienenden Walzen ein gesondertes Fühlerelement zum Abtasten der Luftblase vorgesehen ist. Dieses Fühlerelement ist ebenso wie die Düse auf der unteren Seite des etwa horizontal geführten strangförmigen Gutes angeordnet und dient dazu, durch Steuerung der Luftzufuhr die Grösse der Luftblase zu begrenzen. Das strangförmige Gut ist dabei im Bereich der Abtastung frei geführt und steht lediglich auf der einen, unteren Seite mit dem Fühlerelement in Kontakt. Die Düse ist hierbei in Abstand zum strangförmigen Gut angeordnet und muss auch wegen der mangelnden Führung der Luftblase einen Abstand vom Gut aufweisen, um Beschädigungen des Textilgutes an der Düse zu vermeiden.A device for wet treatment of strand-like material is also known (FR-A-2 193 333), in which a separate sensor element for scanning the air bubble is provided in front of the two rollers used to retain the air bubble. This sensor element, like the nozzle, is arranged on the lower side of the approximately horizontally guided strand-shaped material and serves to limit the size of the air bubble by controlling the air supply. The strand-like material is guided freely in the area of the scanning and is only in contact with the sensor element on one lower side. The nozzle is arranged at a distance from the strand-like material and must also be at a distance from the material due to the lack of guidance of the air bubble in order to avoid damage to the textile material on the nozzle.

Ein wesentlicher Nachteil dieser bekannten Vorrichtung besteht darin, dass das Fühlerelement gegenüber Änderungen der Grösse der Luftblase sehr unempfindlich ist, so dass kritische Betriebsverhältnisse u.U. nicht schnell genug erfasst und durch Änderung der Luftzufuhr korrigiert werden. Nachteilig ist weiterhin der grosse Luftverbrauch, der sich durch den notwendigen Abstand der Düse vom Strangförmigen Textilgut ergibt.A major disadvantage of this known device is that the sensor element is very insensitive to changes in the size of the air bubble, so that critical operating conditions may occur. cannot be detected quickly enough and corrected by changing the air supply. Another disadvantage is the large air consumption, which results from the necessary distance of the nozzle from the strand-like textile material.

Der Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung dieser Mängel der bekannten Ausführungen eine Vorrichtung der im Oberbegriff des Anspruches 1 genannten Art so auszubilden, dass mit einfachen konstruktiven Mitteln eine feinfühlige Überwachung der Luftblase und damit ein absolut zuverlässiger, störungsfreier Betrieb gewährleistet und zugleich der Luftverbrauch verringert wird.The invention is therefore based on the object, while avoiding these deficiencies of the known designs, to design a device of the type mentioned in the preamble of claim 1 in such a way that, using simple constructional means, sensitive monitoring of the air bubble and thus absolutely reliable, trouble-free operation is ensured and at the same time the Air consumption is reduced.

Diese Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.

Durch die Anordnung der Düsenöffnung in einer das Textilgut dicht an der Düsenöffnung vorbeiführenden Führungsfläche ergibt sich ein minimaler Abstand zwischen der Düsenöffnung und dem Textilgut und damit eine wesentliche Verringerung des Luftverbrauches.The arrangement of the nozzle opening in a guide surface leading the textile material close to the nozzle opening results in a minimal distance between the nozzle opening and the textile material and thus a substantial reduction in air consumption.

Indem das Fühlerelement an der der Düsenöffnung abgewandten Seite der Luftblase anliegt und die Luftblase an wenigstens einer weiteren Aussenseite durch ein seitliches Führungselement begrenzt wird, ist die Lage der Luftblase im Bereich des Fühlerelementes eindeutig definiert, so dass Änderungen der Grösse der Luftblase sehr genau und ohne Verzögerung durch das Fühlerelement festgestellt werden.Since the sensor element rests on the side of the air bubble facing away from the nozzle opening and the air bubble is delimited on at least one other outer side by a lateral guide element, the position of the air bubble in the area of the sensor element is clearly defined, so that changes in the size of the air bubble are very precise and without Delay can be determined by the sensor element.

Da das Fühlerelement vor der die Luftblase zurückhaltenden Umlenkwalze angeordnet ist und keine Zurückhaltefunktion bezüglich der Luftblase ausüben muss, kann das Fühlerelement sehr feinfühlig ausgebildet werden. Man erreicht auf diese Weise mit einfachen konstruktiven Mitteln einen absolut zuverlässigen, störungsfreien Betrieb der Vorrichtung.Since the sensor element is arranged in front of the deflecting roller that retains the air bubble and does not have to perform a restraining function with respect to the air bubble, the sensor element can be designed to be very sensitive. In this way, absolutely reliable, trouble-free operation of the device is achieved with simple constructional means.

Bei allen Ausführungsbeispielen wird in der nur jeweils zum Teil dargestellten Nassbehandlungsvorrichtung insbesondere strangförmiges Textilgut 1 nassbehandelt, z. B. gespült oder gewaschen, und dabei in Richtung der Pfeile 2 transportiert.In all of the exemplary embodiments, strand-like textile material 1 in particular is wet-treated in the wet treatment device, which is only partially shown, e.g. B. rinsed or washed, and transported in the direction of arrows 2.

Beim Ausführungsbeispiel gemäss den Fig. 1 und 2 ist in dem hier besonders interessierenden Teil der Nassbehandlungsvorrichtung wenigstens eine Düse 3 für die Zuführung eines Luftstromes (Pfeile 4) vorgesehen. Während Fig. 1 nur eine Düse 3 mit den ihr zugeordneten Teilen zeigt, können je nach Textilgutbreite bzw. je nach Anzahl der nebeneinanderlaufenden Textilgutstränge auch mehrere solcher - gleichartiger - Düsen vorgesehen sein, die dann - senkrecht zur Zeichenebene der Fig. 1 gesehen - hintereinanderliegen.In the exemplary embodiment according to FIGS. 1 and 2, at least one nozzle 3 for supplying an air flow (arrows 4) is provided in the part of the wet treatment device which is of particular interest here. 1 shows only one nozzle 3 with the parts assigned to it, depending on the width of the textile material or the number of adjacent textile material strands, several such - similar - nozzles can also be provided, which - as seen perpendicular to the plane of the drawing in FIG. 1 - lie one behind the other .

Die Düse 3 ist mit einem sich nach aussen erweiternden Mundstück 5 versehen, das das Textilgut 1 dicht an der Düsenöffnung 6 vorbeiführt. Dieses Mundstück wird - wie sich vor allem auch aus Fig. 2 ergibt - im wesentlichen von zwei V-förmig zueinander angeordneten Leitplatten 5a, 5b gebildet, die auf ihren Innenseiten Leitflächen für das Textilgut 1 bilden und von der Düsenöffnung 6 in Richtung des aus der Düse austretenden Luftstromes (Pfeile 4) divergieren. Die Leitplatten können dabei im wesentlichen eben ausgebildet (vgl. Fig. 2) und beispielsweise aus Blech oder geeigneten Kunststoffplatten hergestellt sein. Das Mundstück 5 ist in geeigneter Weise im Bereich der Düsenöffnung 6 so an der Düse 3 befestigt, dass der zu beblasende Textilgutstrang in jedem Falle an der Düsenöffnung 6 (im Bereich der engsten Stelle der V-Form) zwischen den beiden Leitplatten 5a, 5b vorbeigeleitet wird. Zur Grösse der Leitplatten 5a, 5b des Mundstückes 5 sei gesagt, dass diese einerseits ausreichend breit sein sollen, um das Textilgut 1 vor und hinter der Düsenöffnung 6 genügend führen zu können, und anderseits eine ausreichende Länge (in Richtung des aus der Düse 3 austretenden Luftstromes gemäss Pfeil 4 gesehen) aufweisen sollen, damit sie auch bei besonders gross aufgeblähtem Textilgutstrang diesen noch stets seitlich erfassen können. Zweckmässig sind die der Textilgut-Transportrichtung (Pfeil 2) entgegengerichteten Kanten der Leitplatten 5a, 5b abgerundet oder umgebördelt, damit ein schonendes Einführen des Textilgutes 1 in das Mundstück 5 gewährleistet ist. Der die Leitplatten 5a, 5b verbindende Teil des Mundstückes 5, in dem die Düsenöffnung 6 vorgesehen ist, bildet eine Führungsfläche 5c für das Textilgut.The nozzle 3 is provided with an outwardly widening mouthpiece 5 which guides the textile material 1 close to the nozzle opening 6. This mouthpiece is - as can be seen above all from FIG. 2 - essentially formed by two V-shaped guide plates 5a, 5b which form guide surfaces for the textile material 1 on their inner sides and from the nozzle opening 6 in the direction of the The nozzle of the emerging air flow (arrows 4) diverge. The guide plates can be essentially flat (see FIG. 2) and can be made of sheet metal or suitable plastic plates, for example. The mouthpiece 5 is fastened in a suitable manner in the area of the nozzle opening 6 to the nozzle 3 in such a way that the textile material strand to be blown bypasses the nozzle opening 6 (in the area of the narrowest point of the V-shape) between the two guide plates 5a, 5b becomes. Regarding the size of the guide plates 5a, 5b of the mouthpiece 5, it should be said that on the one hand these should be sufficiently wide to be able to guide the textile material 1 in front of and behind the nozzle opening 6 sufficiently, and on the other hand a sufficient length (in the direction of the one emerging from the nozzle 3 Air flow according to arrow 4) should have, so that they can always grasp this laterally even with particularly large inflated textile material strand. The edges of the guide plates 5a, 5b opposite the textile material transport direction (arrow 2) are rounded or flanged so that a gentle insertion of the textile material 1 into the mouthpiece 5 is ensured. The part of the mouthpiece 5 connecting the guide plates 5a, 5b, in which the nozzle opening 6 is provided, forms a guide surface 5c for the textile material.

Für die Wirksamkeit der Düse 3 ist es ferner von Bedeutung, dass sich im Bereich der Düsenöffnung 6 eine Umlenkung für das Textilgut 1 ergibt. Zu diesem Zweck ist bei dem Ausführungsbeispiel gemäss Fig. 1 die Düse 3 schräg nach oben blasend angeordnet, während das strangförmige Textilgut 1 aus einem nicht näher veranschaulichten, darunter liegenden Nassbehandlungsbad etwa senkrecht oder annähernd senkrecht nach oben transportiert wird (Pfeil 2), und zwar in der Weise, dass das Textilgut 1 durch sein Eigengewicht stets auf der Düsenöffnung 6 aufliegt.For the effectiveness of the nozzle 3, it is also important that there is a deflection for the textile material 1 in the region of the nozzle opening 6. For this purpose, in the exemplary embodiment according to FIG. 1, the nozzle 3 is arranged to blow obliquely upwards, while the strand-like textile material 1 is transported approximately vertically or approximately vertically upwards from a wet treatment bath (not shown) (arrow 2) in such a way that the textile material 1 always rests on the nozzle opening 6 due to its own weight.

Bei dieser Führung wird das Textilgut 1 nach Passieren der Düsenöffnung 6 und des Mundstükkes 5 schräg nach oben laufend weitertransportiert. Hierbei ist es wichtig, dass in Bewegungsrichtung des Textilgutes 1 hinter der Düse 3 eine Einrichtung zum Zurückhalten einersich im Textilgut bildenden Luftblase 10 vorgesehen ist. Bei dieser Vorrichtung wird die genannte Zurückhalteeinrichtung durch zwei Umlenkwalzen 8, 9 gebildet, die in diesem Falle etwa schräg hintereinander angeordnet sind und nacheinander von dem in Richtung des Pfeiles 2 transportierten Textilgut 1 passiert werden. Wie sich aus Fig. 1 deutlich entnehmen lässt, sorgt vor allem die zuerst vom Textilgut 1 passierte Umlenkwalze 8 dafür, dass das auf sie auflaufende Textilgut 1 durch die erste Umlenkung so zusammengedrückt wird, dass die im Bereich zwischen dieser Umlenkwalze 8 und Mundstück 5 bzw. Düse 3 vorhandene Luftblase 10 nicht über diese Umlenkwalzen hinauswandern kann.With this guidance, the textile material 1 is conveyed continuously upwards after passing through the nozzle opening 6 and the mouthpiece 5. It is important here that, in the direction of movement of the textile material 1, a device is provided behind the nozzle 3 for holding back an air bubble 10 which forms in the textile material. In this device, the above-mentioned restraint device is formed by two deflecting rollers 8, 9, which in this case are arranged approximately obliquely one behind the other and are successively passed by the textile material 1 transported in the direction of arrow 2. As can be clearly seen from FIG. 1, the deflecting roller 8 first passed through the textile material 1 ensures that the textile material 1 running onto it is compressed by the first deflection such that the area between this deflecting roller 8 and mouthpiece 5 or Nozzle 3 existing air bubble 10 cannot migrate beyond these deflecting rollers.

In vielen Fällen, beispielsweise bei der Behandlung von Schlauchware oder dgl., ist es wichtig, die Luftzufuhr zum Textilgut 1 zu steuern. Zu diesem Zweck ist innerhalb der Düse 3 eine als Steuerorgan vorgesehene Drosselklappe 11 eingebaut, die zwischen einer vollkommen geöffneten und einer vollkommen geschlossenen Stellung eingestellt werden kann. Diese Drosselklappe 11 wird in diesem Ausführungsbeispiel in Abhängigkeit von der Schwenklage eines Steuerbügels 12 eingestellt, der auf der der Düsenöffnung 6 gegenüberliegenden Seite des Textilgutstranges gelenkig angeordnet ist und von der Textilgut 1 gebildeten Luftblase 10 geschwenkt werden kann. Im veranschaulichten Ausführungsbeispiel wird der Einfachheit halber angenommen, dass dieser Steuerbügel 12 an seinem in Transportrichtung (Pfeil 2) des Textilgutes 1 weisenden Ende über eine Gelenkachse 13 vom Mundstück 5 getragen wird. Der Steuerhebel 12 kann dann um seine Gelenkachse 13 in Richtung des Doppelpfeiles 14 geschwenkt werden, indem er stets auf der genannten Seite des Textilgutes 1 aufliegt und dadurch die Grösse der Luftblase 10 abtastet. Der Steuerbügel 12 ist über eine Gelenkstelle 15 und ein Verbindungsgestänge 16 mit der Drosselklappe 11, insbesondere mit deren Schwenkachse 11a, verbunden (vgl. Fig. 1).In many cases, for example in the treatment of tubular goods or the like, it is important to control the air supply to the textile material 1. For this purpose, a throttle valve 11, which is provided as a control element, is installed inside the nozzle 3 and can be adjusted between a fully open and a completely closed position. In this exemplary embodiment, this throttle valve 11 is set as a function of the swivel position of a control bracket 12 which is articulated on the side of the textile material strand opposite the nozzle opening 6 and can be pivoted by the air bubble 10 formed by the textile material 1. In the illustrated exemplary embodiment, for the sake of simplicity, it is assumed that this control bracket 12 is carried by the mouthpiece 5 at its end pointing in the transport direction (arrow 2) of the textile material 1 via an articulated axis 13. The control lever 12 can then be pivoted about its hinge axis 13 in the direction of the double arrow 14 by always resting on the said side of the textile material 1 and thereby scanning the size of the air bubble 10. The control bracket 12 is connected to the throttle valve 11, in particular to its pivot axis 11a, via a hinge point 15 and a connecting linkage 16 (cf. FIG. 1).

Diese Verbindung zwischen der Drosselklappe 11 und Steuerbügel 12 sollte eine Steuerung in der Weise gestatten, dass dieser Steuerbügel 12 schon bei einer geringen Auslenkung ein Schliessen der Drosselklappe 11 bewirken kann, wobei jedoch gleichzeitig sichergestellt werden muss, dass eine weitergehende Auslenkung des Steuerbügels 12 durch einen Freihub dieses Bügels möglich ist, damit dieser Steuerbügel 12 die Transportbewegung des Strangförmigen Textilgutes 1 in keiner Weise behindert.This connection between the throttle valve 11 and the control bracket 12 should permit control in such a way that this control bracket 12 can cause the throttle valve 11 to close even with a slight deflection, but at the same time it must be ensured that a further deflection of the control bracket 12 by a Free stroke of this bracket is possible so that this control bracket 12 in no way hinders the transport movement of the strand-like textile material 1.

Was die Zufuhr der Luft anbelangt, so wird es vorgezogen, diese aus dem Innenraum des Nassbehandlungsbehälters, z.B. des Kufeninnenraumes, der Düse 3 zuzuführen. Zu diesem Zweck ist die Düse 3 an dem einen Ende eines Luftzuleitungsrohres 17 angebaut, in dem ein beispielsweise als Axialventilator ausgeführter Ventilator 18 angeordnet ist, der den Luftstrom 4 für das Beblasen des Textilgutes 1 erzeugt.As for the supply of air, it is preferred to remove it from the interior of the wet treatment tank, e.g. of the interior of the runner to feed the nozzle 3. For this purpose, the nozzle 3 is attached to one end of an air supply pipe 17, in which a fan 18, for example an axial fan, is arranged, which generates the air flow 4 for blowing the textile material 1.

Versuche haben ergeben, dass eine besonders günstige Beblasung des strangförmigen Textilgutes 1 erzielt werden kann, wenn der Ventilator 18 für die Erzeugung eines Luftstromes 4 mit einem Druck von etwa 2500 mm WS ausgelegt ist; dabei kann eine Düse gewählt werden, deren Düsenöffnung 6 einen Durchmesser von etwa 3 mm besitzt.Trials have shown that a particular one Favorable blowing of the strand-like textile material 1 can be achieved if the fan 18 is designed for generating an air flow 4 with a pressure of approximately 2500 mm water column; a nozzle can be selected, the nozzle opening 6 of which has a diameter of approximately 3 mm.

Während bei diesem anhand der Fig. 1 und 2 geschilderten ersten Ausführungsbeispiel die Abtasteinrichtung für die Luftblase einen Steuerbügel 12 enthält, der über ein Verbindungsgestänge 16 mit der Luftzufuhr-Drosselklappe 11 in Steuerverbindung steht, kann die Abtasteinrichtung mit den zugehörigen Steuerelementen auch anders ausgebildet sein, wie die folgenden Ausführungsbeispiele zeigen.While in this first exemplary embodiment described with reference to FIGS. 1 and 2, the scanning device for the air bubble contains a control bracket 12 which is in control connection with the air supply throttle valve 11 via a connecting rod 16, the scanning device with the associated control elements can also be designed differently, as the following examples show.

Auch beim zweiten Ausführungsbeispiel gemäss den Fig. 3 bis 5 wird das strangförmige Textilgut 1 wiederum von unten nach oben in Richtung der Pfeile 2 transportiert und über wenigstens eine Umlenkwalze 8 so umgelenkt, dass eine sich durch Luftbeblasung innerhalb des Textilgutstranges bildende Luftblase 10 zurückgehalten wird, wie es bereits anhand des ersten Ausführungsbeispieles (Fig. 1 und 2) geschildert worden ist.3 to 5, the strand-like textile material 1 is again transported from bottom to top in the direction of the arrows 2 and deflected via at least one deflecting roller 8 in such a way that an air bubble 10 formed by air blowing within the textile material strand is retained. as has already been described with the aid of the first exemplary embodiment (FIGS. 1 and 2).

Bei diesem zweiten Ausführungsbeispiel enthält die gesonderte Abtasteinrichtung 20 ein Fühlerelement in Form eines geschlossenen Steuerbügels 21, der an der dem Düsenrohr 22 mit der Düsenöffnung 22a abgewandten Seite der Luftblase 10 anliegt. Wie sich aus den Querschnittsdarstellungen der Fig. 3 und 4 deutlich erkennen lässt, wird der Steuerbügel 21 von einem rohrförmigen Steuerkörper 23 getragen, mit dem er drehfest verbunden ist. Dieser rohrförmige Steuerkörper 23 umschliesst ein Luftzuleitungsrohr 24 relativ eng, jedoch drehbeweglich auf einem kurzen Längsabschnitt des Luftzuleitungsrohres 24 (vgl. Fig. 5). Der Steuerkörper 23 ist durch ein ihn umfassendes, bogenförmiges Rohranschlusselement 25 in seiner axialen Lage festgelegt, wobei das Rohranschlusselement 25 auf das Luftzuleitungsrohr 24 aufgeschweisst ist. Die Drehbeweglichkeitdes Steuerkörpers 23 in Richtung des Doppelpfeiles 26 wird begrenzt durch einen im Luftzuleitungsrohr 24 vorgesehenen Führungsschlitz 27, in den ein drehfest mit dem Steuerkörper 23 verbundener Anschlagzapfen 28 eingreift. Gegenüber dem Führungsschlitz 27 in Umfangsrichtung versetzt ist eine Öffnung 29 im Luftzuleitungsrohr 24 vorgesehen, die einer gleichgrossen Öffnung 30 im Rohranschlusselement 25 gegenüberliegt, an das ein Verbindungsrohr 31 zum Düsenrohr 22 angeschlossen ist. In dem Steuerkörper 23 ist nun eine weitere Durchgangsöffnung 32 vorgesehen, die die gleiche Grösse besitzt wie die Öffnungen 29 und 30 und die so angeordnet ist, dass sie in der einen Drehendstellung des Steuerkörpers 23 eine Luftströmung aus dem Luftzuleitungsrohr 24 in das Verbindungsrohr 31 bzw. durch die Öffnungen 29, 30 hindurch verhindert (=geschlossene Stellung gemäss Fig. 3) und die in der anderen Drehendstellung des Steuerkörpers 23 genau zu den Öffnungen 29 und 30 ausgerichtet ist, so dass sie - gemäss Fig. 4 - eine vollkommen offene Verbindung zwischen dem Luftzuleitungsrohr 24 und dem Verbindungsrohr 31 bzw. zwischen den Öffnungen 29 und 30 herstellt. Es ergibt sich auf diese Weise ein Luft-Steuerventil, das in Abhängigkeit von der Stellung des Steuerbügels 21 und somit in Abhängigkeit von der Grösse der Luftblase 10 im Textilgut 1 die Luftzufuhr vom Luftzuleitungsrohr 24 über das Verbindungsrohr 31 zur Düsenöffnung 22a steuert. Wie ein Vergleich zwischen den Fig. 3 und 4 zeigt, wird die Luftzufuhr durch den Steuerkörper 23 unterbrochen, wenn die Luftblase 10 im Textilgut 1 zu gross wird, und vollkommen geöffnet, wenn die Luftblase 10 im Textilgut 1 zu klein bzw. praktisch gar keine Luft im Textilgut 1 ist; es können auf diese Weise selbstverständlich auch Zwischenstellungen geregelt werden.In this second exemplary embodiment, the separate scanning device 20 contains a sensor element in the form of a closed control bracket 21, which rests on the side of the air bubble 10 facing away from the nozzle tube 22 with the nozzle opening 22a. As can be clearly seen from the cross-sectional representations of FIGS. 3 and 4, the control bracket 21 is carried by a tubular control body 23 to which it is connected in a rotationally fixed manner. This tubular control body 23 surrounds an air supply pipe 24 relatively closely, but rotatably on a short longitudinal section of the air supply pipe 24 (cf. FIG. 5). The control body 23 is fixed in its axial position by an arcuate pipe connection element 25 which surrounds it, the pipe connection element 25 being welded onto the air supply pipe 24. The rotational mobility of the control body 23 in the direction of the double arrow 26 is limited by a guide slot 27 provided in the air supply pipe 24, into which a stop pin 28 engages in a rotationally fixed manner with the control body 23. An opening 29 is provided in the air supply pipe 24 opposite the guide slot 27 in the circumferential direction and is opposite an opening 30 of the same size in the pipe connection element 25, to which a connecting pipe 31 to the nozzle pipe 22 is connected. A further through-opening 32 is now provided in the control body 23, which has the same size as the openings 29 and 30 and which is arranged in such a way that in the one rotational end position of the control body 23 an air flow from the air supply pipe 24 into the connecting pipe 31 or prevented through the openings 29, 30 (= closed position according to FIG. 3) and which in the other rotary end position of the control body 23 is aligned precisely with the openings 29 and 30, so that - according to FIG. 4 - they are a completely open connection between the air supply pipe 24 and the connecting pipe 31 or between the openings 29 and 30. This results in an air control valve which controls the air supply from the air supply pipe 24 via the connecting pipe 31 to the nozzle opening 22a as a function of the position of the control bracket 21 and thus as a function of the size of the air bubble 10 in the textile material 1. As a comparison between FIGS. 3 and 4 shows, the air supply through the control body 23 is interrupted when the air bubble 10 in the textile material 1 becomes too large, and completely opened when the air bubble 10 in the textile material 1 is too small or practically none Air in textile material 1; it is of course also possible to regulate intermediate positions in this way.

Den Fig. 3 und 4 lässt sich ferner entnehmen, dass die Schwenkachse des Steuerbügels 21, die in diesem Falle mit der Rohrlängsachse 33 des Luftzuleitungsrohres 24 zusammenfällt, tiefer liegt als der zur Anlage an das Textilgut 1 kommende Teil 21a des Steuerbügels; diese Anordnung und Ausbildung bewirkt, dass der Steuerbügel 21 durch sein Eigengewicht am Textilgut 1, und zwar an der der Düsenöffnung 22a abgewandten Seite, anliegt. In diesem Ausführungsbeispiel befindet sich auch das Luftzuleitungsrohr 24 mit dem darauf angeordneten Steuerkörper 23 auf der der Düsenöffnung 22a abgewandten Seite des Textilgutes 1; das Verbindungsrohr 31 zwischen Luftzuleitungsrohr 24 und Düsenrohr 22 muss daher so geführt sein, dass es die Bewegung des Textilgutstranges nicht behindert.3 and 4 can also be seen that the pivot axis of the control bracket 21, which in this case coincides with the longitudinal axis 33 of the air supply pipe 24, is lower than the part 21a of the control bracket which comes into contact with the textile material 1; this arrangement and design has the effect that the control bracket 21 lies against the textile material 1 by its own weight, namely on the side facing away from the nozzle opening 22a. In this exemplary embodiment, the air supply pipe 24 with the control body 23 arranged thereon is also located on the side of the textile material 1 facing away from the nozzle opening 22a; the connecting pipe 31 between the air supply pipe 24 and the nozzle pipe 22 must therefore be guided so that it does not hinder the movement of the textile material strand.

Das Düsenrohr 22 kann über seine Länge mit einer Anzahl von einzelnen Düsenöffnungen 22a versehen sein oder auch einen durchgehenden Düsenschlitz aufweisen. Das Düsenrohr 22 bildet jedenfalls eine Führungsfläche, die das Textilgut dicht an der Düsenöffnung 22a vorbeiführt.The nozzle tube 22 can be provided with a number of individual nozzle openings 22a along its length or can also have a continuous nozzle slot. In any case, the nozzle tube 22 forms a guide surface, which guides the textile material close to the nozzle opening 22a.

Die Breite des Steuerbügels 21 (gesehen in Richtung der Arbeitsbreite, parallel zum Düsenrohr 22) wird sich im allgemeinen nach der Grösse bzw. Breite des zu behandelnden Textilgutes 1 richten. Bei der in Fig. 5 - in der Aufsicht - dargestellten Ausführungsform der Abtasteinrichtung 20 ist der Steuerbügel 21 für verhältnismässig schmale Textilgutstränge entsprechend schmal ausgeführt.The width of the control bracket 21 (viewed in the direction of the working width, parallel to the nozzle tube 22) will generally depend on the size or width of the textile material 1 to be treated. In the embodiment of the scanning device 20 shown in FIG. 5, the control bracket 21 is designed to be correspondingly narrow for relatively narrow strands of textile material.

Fig. 6 zeigt dagegen eine Ausführungsvariante, bei der die Abtasteinrichtung 20' für verhältnismässig breites Textilgut bzw. verhältnismässig breite Textilgutstränge bestimmt ist. Der Steuerbügel 21' besitzt daher auch eine verhältnismässig grosse Breite, und auf dem Luftzuleitungsrohr 24 sind daher auch zwei Steuerkörper 23' mit entsprechendem axialen Abstand jeweils in der gleichen Weise angeordnet, wie es anhand der Fig. 3 und 4 beschrieben und veranschaulicht ist. Der Steuerbügel 21' ist in diesem Falle mit beiden Steuerkörpern 23' drehfest auf derselben Luftzuführleitung 24 schwenkbar angeordnet. Im Bereich beider Steuerkörper 23' ist je ein Verbindungsrohr 31' in der gleichen Weise wie im Falle der Fig. 3 und 4 an dasselbe Luftzuleitungsrohr 24 angeschlossen, wobei beide Verbindungsrohre 31' etwa die gleiche Länge - zwischen Luftzuleitungsrohr 24 und Düsenrohr 22'- aufweisen. Diese beiden Verbindungsrohre 31' sind dabei dann zu beiden Seiten des Strangquerschnittes des Textilgutes zum Düsenrohr 22' geführt.FIG. 6, on the other hand, shows an embodiment variant in which the scanning device 20 'is intended for relatively wide textile goods or relatively wide textile material strands. The control bracket 21 'therefore also has a relatively large width, and therefore two control bodies 23' with a corresponding axial distance are each arranged in the same manner on the air supply pipe 24, as is described and illustrated with reference to FIGS. 3 and 4. The control bracket 21 'is in this case rotatably arranged with two control bodies 23' on the same air supply line 24. In the area of both control bodies 23 ', a connecting pipe 31' is connected in the same way as in the case of FIGS. 3 and 4 to the same air supply pipe 24, both connecting pipes 31 'have approximately the same length - between the air supply pipe 24 and the nozzle pipe 22'. These two connecting tubes 31 'are then guided to the nozzle tube 22' on both sides of the strand cross section of the textile material.

Eine weitere Modifikation der anhand der Fig. 5 und 6 geschilderten Ausführungsvarianten der gesonderten Abtasteinrichtung lässt sich noch dadurch erzielen, dass bei der Verwendung von zwei Steuerkörpern mit diesen beiden Steuerkörpern entweder ein gemeinsames breites Fühlerelement (entsprechend Fig. 6) oder je ein schmales Fühlerelement (beispielsweise entsprechend Fig.5) verbindbar ist, so dass die Nassbehandlungsvorrichtung für eine alternative Behandlung von breit oder schmal geführtem strangförmigen Textilgut verwendet werden kann.A further modification of the embodiment variants of the separate scanning device described with reference to FIGS. 5 and 6 can also be achieved in that when using two control bodies with these two control bodies either a common wide sensor element (corresponding to FIG. 6) or a narrow sensor element ( 5) can be connected, for example, so that the wet treatment device can be used for an alternative treatment of broadly or narrowly guided strand-like textile material.

Eine baulich besonders einfache Ausführungsform bedeutet das in den Fig. 7 bis 9 veranschaulichte dritte Ausführungsbeispiel der Vorrichtung.A structurally particularly simple embodiment means the third exemplary embodiment of the device illustrated in FIGS. 7 to 9.

Das vorzugsweise strangförmige Textilgut 1 wird jeweils zunächst wieder in ähnlicher Weise wie bei den vorhergehenden Ausführungsbeispielen - in Richtung der Pfeile 2 - von unten nach oben transportiert und dabei über wenigstens eine Umlenkwalze 8 herumgeführt, die zum Zurückhalten einer im Textilgut 1 zu bildenden Luftblase 10 bestimmt ist.The preferably strand-like textile material 1 is first transported in a manner similar to that in the previous exemplary embodiments - in the direction of the arrows 2 - from the bottom upwards and is guided around at least one deflecting roller 8 which is intended to retain an air bubble 10 to be formed in the textile material 1 is.

Im Bereich unterhalb bzw. - in Bewegungsrichtung (Pfeile 2) des Textilgutes 1 gesehen -vor der Umlenkwalze 8 ist ein die Luft zuführendes Düsenrohr 35 angeordnet. Das Düsenrohr 35 reicht - senkrecht zur Zeichenebene der Fig. 7 und 8 - etwa über die ganze Arbeitsbreite der Nassbehandlungsvorrichtung und kann eine oder mehrere Durchgangsöffnungen 36 (ggfs. ist jedoch auch wenigstens ein Durchgangsschlitz möglich).In the area below or - seen in the direction of movement (arrows 2) of the textile material 1 - in front of the deflecting roller 8, a nozzle tube 35 which supplies the air is arranged. The nozzle tube 35 extends - perpendicular to the plane of the drawing in FIGS. 7 and 8 - approximately over the entire working width of the wet treatment device and can have one or more through openings 36 (if necessary, however, at least one through slot is also possible).

Die auch in diesem Falle gesondert angeordnete Abtasteinrichtung 37 für die Luftblase 10 bzw. das Textilgut 1 enthält auch hier ein schwenkbares Fühlerelement in Form eines Steuerbügels 38, der- in ähnlicher Weise wie beim zweiten Ausführungsbeispiel gemäss Fig. 3 bis 6 - mit wenigstens einem die Luftzufuhr zur Düse bestimmenden Düsenkörper 39 drehfest verbunden ist. Bei diesem Ausführungsbeispiel ist die wiederum mit der Rohrlängsachse 40 des Düsenrohres 35 zusammenfallende Schwenkachse des Steuerbügels 38 auf derselben Seite des strangförmigen Textilgutes 1 wie die Düse bzw. das Düsenrohr 35 angeordnet. Der das Textilgut 1 bzw. dessen Luftblase 10 abtastende Teil des Steuerbügels 38 befindet sich dagegen auf der dem Düsenrohr 35 abgewandten Seite des Textilgutes und wird reibschlüssig vom Teil 38b strangförmigen Textilgut 1 mitgenommen. Der Steuerbügel 38 umschliesst das strangförmige Textilgut 1 wenigstens mit drei Seiten. Wie in Fig. 9 dargestellt ist, kann dieser Steuerbügel 38 jedoch vorzugsweise in Form eines vollkommen geschlossenen Bügels ausgebildetsein und dabei einen den Strangquerschnitt 1a auf der einen (vierten) Seite begrenzenden, verstellbaren Steg 42 aufweisen, der über die ganze Breite des Steuerbügels 38 reicht und-wie gestrichelt angedeutet ist-in verschiedenen Stellungen eingeschoben werden kann (beispielsweise durch gegenüberliegende Bohrungen in den Seitenstreben 38a des Steuerbügels 38).The separately arranged scanning device 37 for the air bubble 10 or the textile material 1 also contains a pivotable sensor element in the form of a control bracket 38, which - in a similar manner to the second exemplary embodiment according to FIGS. 3 to 6 - with at least one Air supply to the nozzle-determining nozzle body 39 is rotatably connected. In this exemplary embodiment, the pivot axis of the control bracket 38, which in turn coincides with the tube longitudinal axis 40 of the nozzle tube 35, is arranged on the same side of the strand-like textile material 1 as the nozzle or the nozzle tube 35. The part of the control bracket 38 which scans the textile material 1 or its air bubble 10, on the other hand, is located on the side of the textile material facing away from the nozzle pipe 35 and is frictionally carried along by the part 38b of strand-like textile material 1. The control bracket 38 encloses the strand-like textile material 1 at least on three sides. As shown in FIG. 9, however, this control bracket 38 can preferably be designed in the form of a completely closed bracket and in this case have an adjustable web 42 which delimits the strand cross section 1a on one (fourth) side and extends over the entire width of the control bracket 38 and — as indicated by dashed lines — can be inserted in different positions (for example through opposite bores in the side struts 38a of the control bracket 38).

Für einen Steuerbügel 38 genügt in diesem Falle ein einziger Steuerkörper 39, der sich etwa über die Breite eines Textilgutstranges (vgl. Fig. 9) erstrecken kann. Der Steuerkörper 39 ist dabei wiederum rohrförmig ausgebildet und umfasst das Düsenrohr 35 relativ eng, wobei er jedoch in Richtung des Doppelpfeiles 41 begrenzt drehbeweglich ist und an seinen Enden durch nicht näher veranschaulichte Begrenzungsstücke - ähnlich wie beim zweiten Ausführungsbeispiel gemäss den Fig. 3 bis 6 - in seiner axialen Lage festgelegt ist. Zweckmässigerweise ist an dem Steuerkörper 39 - wie in den Fig. 7 und 8 dargestellt - noch ein Gegengewicht 43 für den Steuerbügel 38 so angeordnet, dass letzterer- neben seiner reibschlüssigen Mitnahme durch das Textilgut 1 zusätzlich noch gegen die dem Düsenrohr 35 abgewandte Seite des Textilgutes gehalten werden kann. Dieses Gegengewicht kann ggfs. auch in seiner Kraftwirkung einstellbar sein.In this case, a single control body 39 is sufficient for a control bracket 38, which can extend approximately over the width of a strand of textile material (cf. FIG. 9). The control body 39 is again tubular and encompasses the nozzle tube 35 relatively narrowly, although it can be rotated to a limited extent in the direction of the double arrow 41 and at its ends by limit pieces (not illustrated in more detail) - similar to the second exemplary embodiment according to FIGS. 3 to 6. is fixed in its axial position. A counterweight 43 for the control bracket 38 is expediently arranged on the control body 39, as shown in FIGS. 7 and 8, in such a way that the latter, in addition to its frictional entrainment by the textile material 1, also against the side of the textile material facing away from the nozzle tube 35 can be held. This counterweight may also be adjustable in its force effect.

Zu beachten ist bei der Ausbildung des Steuerkörpers 39, dass er in seinem mit der einen Seite des Textilgutes 1 in Berührung stehenden Umfangsbereich wenigstens eine Düsenöffnung 44 aufweist, die je nach Schwenkstellung des Steuerbügels 38 und somit des Steuerkörpers 39 (Schwenkrichtung gemäss Doppel pfeil 41) mit den entsprechenden Durchgangsöffnungen 36 im Düsenrohr 35 zur Deckung gebracht oder dagegen vollkommen verschoben werden kann. Auf diese Weise kann die Luftzufuhr durch das Düsenrohr 35 und dessen Durchgangsöffnungen 36 freigegeben bzw. vollkommen versperrt werden, wobei selbstverständlich ebenfalls Zwischenstellungen möglich sind. Die Schwenkendstellungen von Steuerbügel 38 und Steuerkörper 39 gegenüber dem feststehenden Düsenrohr 35 können durch einen Anschlagzapfen 45 begrenzt werden, der mit einem entsprechend langen Führungsschlitz 46 in Eingriff steht, wobei der Anschlagzapfen 45 im festen Düsenrohr befestigt und der Führungsschlitz 46 im Steuerkörper 39 angeordnet ist (eine umgekehrte Anordnung ist jedoch ebenfalls denkbar). Der die Düsenöffnung 44 enthaltende Steuerkörper 39 bildet eine Führungsfläche, die das Textilgut 1 dicht an der Düsenöffnung 44 vorbeiführt. Ganz allgemein kann eine Nassbehandlungsvorrichtung, wie sie zuvor anhand der verschiedenen Ausführungsbeispiele geschildert worden ist, so aufgebaut sein, dass sie für die Nassbehandlung eines einzigen, ringförmig und endlos zusammengenähten Textilgutstranges bestimmt ist, oder sie kann auch für mehrere parallel nebeneinander laufende, endlos gemachte Textilgutstränge oder auch für einen endlos zusammengenähten und spiralförmig mehrmals durch das Behandlungsbad geführten Textilgutstrang konstruiert sein. Im letzteren Falle kann dann eine der Anzahl der nebeneinander laufenden Strangabschnitte ent- sprechende Anzahl gesonderter Abtasteinrichtungen mit Düsen mit entsprechendem Abstand nebeneinander angeordnet sein. In jedem Falle kann die Nassbehandlungsvorrichtung sowohl für eine kontinuierliche als auch für eine diskontinuierliche Behandlung verwendet werden.When designing the control body 39, it should be noted that it has at least one nozzle opening 44 in its circumferential area which is in contact with one side of the textile material 1 and which, depending on the swivel position of the control bracket 38 and thus of the control body 39 (swivel direction according to double arrow 41) can be made to coincide with the corresponding through openings 36 in the nozzle tube 35 or, on the other hand, can be completely displaced. In this way, the air supply through the nozzle pipe 35 and its through openings 36 can be released or completely blocked, intermediate positions also being possible, of course. The pivoting end positions of control bracket 38 and control body 39 with respect to the fixed nozzle tube 35 can be limited by a stop pin 45 which engages with a correspondingly long guide slot 46, the stop pin 45 being fastened in the fixed nozzle tube and the guide slot 46 being arranged in the control body 39 ( a reverse arrangement is also conceivable). The control body 39 containing the nozzle opening 44 forms a guide surface which guides the textile material 1 close to the nozzle opening 44. In very general terms, a wet treatment device, as has been described above with the aid of the various exemplary embodiments, can be constructed in such a way that it is intended for the wet treatment of a single strand of textile material which is sewn together in an annular and endless manner, or it can also be used for a plurality of endlessly made textile material strands running parallel to one another or can also be constructed for an endlessly sewn together and spirally passed textile strand several times through the treatment bath. In the latter case, the number can then ent of the adjacent running line sections - speaking number of separate sensing devices with nozzles with corresponding spacing next to one another be disposed. In any case the wet treatment device can be used for both continuous and discontinuous treatment.
