- the invention relates to a guide device for strand-like textile material continuously circulated within a wet treatment container.
- the guiding device consists of a guide ring which radially surrounds the textile strand on a vertical circulation path.
- the center axis of the guide ring affects a horizontally oriented deflection roller arranged above it.
- the guide ring is tangent to a pivot axis arranged parallel to the central axis of the deflecting roller, to which the guide ring is attached.
- the guide ring is arranged in the running direction of the strand-shaped textile material behind a driven deflection roller and immediately in front of an annular nozzle exerting a tensile force on the textile material. If the tensile force of the ring nozzle is not sufficient for proper strand circulation or fails completely, the textile material piles up on the ring and loads it. As a result, the pivotably mounted ring exerts a force on a pulling element holding it in a horizontal position, whereupon the pulling element actuates a switch which interrupts the drive of the deflecting roller.
- the treatment process can only be continued after a manual intervention to remove the accumulation of textile goods.
- strand-like textile goods are circulated exclusively by a treatment liquor or ring nozzle acted upon with gaseous propellant and a non-driven deflecting roller arranged upstream in the strand circulation direction, the strand may come to a standstill in such a way that the tensile force of the ring nozzle is insufficient to dissolve a strand package created in the dwell area of the wet treatment container. Since the device described above is completely unsuitable for starting the strand circulation again with the aid of the pivotable guide ring, it has also already been proposed to set a guide ring in rotation about its diagonal axis and thereby exert an increased tensile force on the strand being wound up in the process.

Description
Die Erfindung betrifft eine Leitvorrichtung für innerhalb eines Naßbehandlungsbehälters kontinuierlich in Umlauf versetztes strangförmiges Textilgut. Die Leitvorrichtung besteht aus einem den Textilstrang auf einer vertikalen Umlaufstrecke radial umschließenden Führungsring. Die Mittelachse des Führungsringes tangiert eine darüber angeordnete, horizontal ausgerichtete Umlenkwalze. Der Führungsring wird von einer zur Mittelachse der Umlenkwalze parallel angeordneten Schwenkachse tangiert, woran der Führungsring befestigt ist.The invention relates to a guide device for strand-like textile material continuously circulated within a wet treatment container. The guiding device consists of a guide ring which radially surrounds the textile strand on a vertical circulation path. The center axis of the guide ring affects a horizontally oriented deflection roller arranged above it. The guide ring is tangent to a pivot axis arranged parallel to the central axis of the deflecting roller, to which the guide ring is attached.
Bei einer derartigen aus der DE-PS 24 52 185 bekannten Vorrichtung ist der Führungsring in Laufrichtung des strangförmigen Textilguts hinter einer angetriebenen Umlenkwalze und unmittelbar vor einer auf das Textilgut eine Zugkraft ausübenden Ringdüse angeordnet. Reicht die Zugkraft der Ringdüse für den ordnungsgemäßen Strangumlauf nicht oder fällt gänzlich aus, häuft sich das Textilgut auf dem Ring und belastet diesen. Dadurch übt der schwenkbar gelagerte Ring an einem ihn an sich in horizontaler Position haltenden Zugorgan eine Kraft aus, worauf das Zugorgan einen den Antrieb der Umlenkwalze unterbrechenden Schalter betätigt. Erst nach einem die Textilgutanhäufung beseitigenden manuellen Eingriff kann der Behandlungsvorgang fortgesetzt werden.In such a device known from DE-PS 24 52 185, the guide ring is arranged in the running direction of the strand-shaped textile material behind a driven deflection roller and immediately in front of an annular nozzle exerting a tensile force on the textile material. If the tensile force of the ring nozzle is not sufficient for proper strand circulation or fails completely, the textile material piles up on the ring and loads it. As a result, the pivotably mounted ring exerts a force on a pulling element holding it in a horizontal position, whereupon the pulling element actuates a switch which interrupts the drive of the deflecting roller. The treatment process can only be continued after a manual intervention to remove the accumulation of textile goods.
Erfolgt der Umlauf von strangförmigem Textilgut ausschließlich durch eine mit Behandlungsflotte oder mit gasförmigem Treibmittel beaufschlagte Ringdüse, der in Strangumlaufrichtung eine nicht angetriebene Umlenkwalze vorgelagert ist, kann es dadurch zu einem Strangstillstand kommen, daß die Zugkraft der Ringdüse nicht ausreicht, ein im Verweilbereich des Naßbehandlungsbehälters entstandenes Strangpaket aufzulösen. Da die zuvor beschriebene Vorrichtung gänzlich ungeeignet ist, mit Hilfe des schwenkbaren Führungsringes den Strangumlauf wieder in Gang zu setzen, wurde auch schon vorgeschlagen, einen Führungsring um seine Diagonalachse in Rotation zu versetzen und dadurch auf den sich dabei aufwickelnden Strang eine erhöhte Zugkraft auszuüben. Abgesehen davon, daß nach Auflösung des Strangpaketes die Drehbewegungen des Führungsringes um exakt den gleichen Gesamtdrehwinkel rückgängig zu machen sind, damit der Führungsring seine eigentliche Funktion wieder übernehmen kann, wird auf den Strang in beiden Richtungen eine erhöhte Zugkraft ausgeübt und dabei auch ein Strangstück auf den Ring aufgewickelt, das der Zugkraft der Ringdüse ausgesetzt ist bzw. diese bereits passiert hat. Dadurch wird dieser Strangteil übermäßig strapaziert, was zu Schädigungen des Textilguts führen kann.If strand-like textile goods are circulated exclusively by a treatment liquor or ring nozzle acted upon with gaseous propellant and a non-driven deflecting roller arranged upstream in the strand circulation direction, the strand may come to a standstill in such a way that the tensile force of the ring nozzle is insufficient to dissolve a strand package created in the dwell area of the wet treatment container. Since the device described above is completely unsuitable for starting the strand circulation again with the aid of the pivotable guide ring, it has also already been proposed to set a guide ring in rotation about its diagonal axis and thereby exert an increased tensile force on the strand being wound up in the process. In addition to the fact that after the strand package has been released, the rotary movements of the guide ring must be reversed by exactly the same total angle of rotation so that the guide ring can take over its actual function again, an increased tensile force is exerted on the strand in both directions and a strand piece on the same Coil wound, which is exposed to the tensile force of the ring nozzle or has already passed. As a result, this strand part is excessively stressed, which can lead to damage to the textile goods.
Der Erfindung liegt die Aufgabe zugrunde, eine Leitvorrichtung der eingangs beschriebenen Art so auszubilden, daß sich damit in schonungsvoller Weise Störungen im Strangumlauf beseitigen lassen.The invention is based on the object of designing a guide device of the type described at the outset in such a way that faults in the line circulation can be eliminated in a gentle manner.
Zur Lösung dieser Aufgabe wird von einer Leitvorrichtung der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die in seinem kennzeichnenden Teil angegebenen Merkmale aufweist.To achieve this object, a guiding device of the generic type mentioned in the preamble of
Durch die auf ca. 270° begrenzte Schwenkbewegung des Führungsringes und des daran befestigten Trägers wird dieser, bis er seine Endstellung erreicht hat, zunehmend vom Textilstrang umschlungen. Da auf dem Schwenkweg die Strangstrecke zwischen der Umlaufwalze und dem Träger konstant bleibt, sich dabei aber von der tiefsten Position des Trägers bis zu seiner höchsten Position im Schwenkbereich zwischen 90 und 270° die Strangstrecke zwischen dem aufzulösenden Strangpaket und dem Träger mindestens um den Schwenkradius des Trägers vergrößert, resultiert aus dieser Verlagerung des Trägers eine im wesentlichen in Umlaufrichtung des Textilstranges gerichtete Zugkraft, um das Strangpaket aufzulösen. Sodann läßt sich der Träger mit dem Führungsring in die Ausgangsposition zurückschwenken und dieser Vorgang - soweit überhaupt erforderlich - wiederholen.Due to the pivoting movement of the guide ring and the carrier attached to it, limited to approximately 270 °, the textile strand increasingly wraps around it until it has reached its end position. Since the strand path between the circulating roller and the carrier remains constant on the swivel path, however, the strand path between the strand package to be dissolved and the carrier is at least about the swivel radius of from the lowest position of the carrier to its highest position in the swivel range between 90 and 270 ° Enlarged carrier, this displacement of the carrier results in a tensile force essentially directed in the circumferential direction of the textile strand to dissolve the strand package. Then the carrier with the guide ring can be pivoted back into the starting position and this process - if necessary at all - repeated.
Nach einer Ausgestaltung der Erfindung besteht der Träger aus einem Längsschenkel eines Rechteckrahmens, der den Führungsring ebenso tangiert wie ein parallel dazu angeordneter, die Schwenkachse bildender Längsschenkel des Rechteckrahmens.According to one embodiment of the invention, the carrier consists of a longitudinal leg of a rectangular frame which touches the guide ring as well as a longitudinal leg of the rectangular frame arranged parallel to it and forming the pivot axis.
Durch diese Ausgestaltung stellt die Leitvorrichtung insgesamt eine verwindungssteife Konstruktion dar, die der ihr abverlangten Zugkraft ohne die Gefahr einer Verformung standhält.As a result of this configuration, the guide device as a whole is a torsionally rigid construction which can withstand the tensile force required of it without the risk of deformation.
Schließlich sieht eine Ausgestaltung der Erfindung noch vor, daß Seitenschenkel des Rechteckrahmens über den den Träger bildenden Längsschenkel vorstehen und diesen U-förmig ergänzen. Durch diese Ausgestaltung ist sichergestellt, daß der Textilstrang auch dann nicht über die Enden des Trägers abgleiten kann, wenn der Textilstrang schräg zum Führungsring aus dem Verweilbereich des Naßbehandlungsbehälters herauszuziehen ist.Finally, an embodiment of the invention provides that side legs of the rectangular frame protrude beyond the longitudinal leg forming the support and complement it in a U-shape. This configuration ensures that the textile strand cannot slide over the ends of the carrier even if the textile strand is to be pulled out of the dwell area of the wet treatment container at an angle to the guide ring.

Die Leitvorrichtung besteht im wesentlichen aus einem in Normalposition horizontal angeordneten Führungsring 1, durch den ein Textilstrang 2 in Pfeilrichtung über eine nicht angetriebene Umlenkwalze 3 von einer Ringdüse 4 in Umlauf gebracht wird.The guiding device essentially consists of a
Die vertikal ausgerichtete Mittelachse des unterhalb der Umlenkwalze 3 angeordneten Führungsringes 1 tangiert den Mantel der Umlenkwalze 3, während eine von einem nicht dargestellten Antrieb betätigte Schwenkachse 5, die parallel zur Umlenkwalze 3 angeordnet ist, den Führungsring 1 tangiert. Auf der der Schwenkachse 5 gegenüberliegenden Seite wird der Führungsring 1 von einem stangenförmigen Träger 6 tangiert. Die Schwenkachse 5 und der Träger 6 bilden die Längsschenkel eines den Ring einschließenden Rechteckrahmens 7, der durch Seitenschenkel 8 vervollständigt wird. Je ein Ende 9 der Seitenschenkel 8 steht über den Träger 6 vor und ergänzt diesen U-förmig, so daß der vom Träger 6 erfaßte Textilstrang 2 nicht abgleiten kann.The vertically aligned central axis of the
Wie Fig. 1 erkennen läßt, kann der Rechteckrahmen 7 um die Schwenkachse 5 auf der in durchgezogenen Linien dargestellten normalen Position a über 270° in die in strichpunktierten Linien dargestellte Position b verschwenkt werden. Dabei umschlingt der Textilstrang 2 zunehmend den Träger 6 und wird von diesem um etwa die Höhe h von einem nicht dargestellten Strangpaket abgezogen, wogegen unterdessen die Strecke des Textilstranges 2 zwischen der Umlenkwalze 3 und dem Träger 6 unverändert bleibt.As can be seen in FIG. 1, the
