Description
Die Erfindung bezieht sich auf ein Verfahren der dem Oberbegriff des Anspruchs 1 entsprechenden Art sowie eine Anlage gemäß dem Oberbegriff des Anspruchs 7.The invention relates to a method of the preamble of Claim 1 corresponding type and an investment according to the preamble of claim 7.
Aus der DE 195 27 110 C1 geht eine Anlage hervor, die einen Jigger mit zwei Wickelwalzen umfaßt, zwischen die zwei Tauchbecken geringen Inhalts eingeschaltet sind, durch die die Warenbahn beim Umwickeln oder beim Auskaulen hindurchläuft. Beim Auskaulen passiert die Warenbahn einen Saugschlitz, der am Wickelarm kurz vor der Andrückrolle angeordnet ist, die gegen die auf einem Kaulenwagen außerhalb des Jiggers sich bildende Kaule anliegt. Derartige Jigger dienen meist zum Färben von textilen Warenbahnen. Die Auftragsmenge an Flotte ist durch das Flottentragevermögen der Warenbahn begrenzt. Manchmal ergibt sich das Problem, daß diese Grenze zumindest teilweise überschritten ist und sich Flotte innerhalb der Kaule im Bereich des unteren Scheitels ansammelt, um dort abzutropfen. Dies führt zu einer ungleichmäßigen Flottenverteilung in der Kaule mit entsprechendem Einfluß auf die Gleichmäßigkeit der Behandlung. Es versteht sich, daß derartige einen "Wassersack" aufweisende Kaulen beim Abwickeln Probleme machen, denen man in manchen Fällen auf aufwendige Weise durch ständiges Drehen der Kaule während der Verweilzeit zu begegnen versucht hat.DE 195 27 110 C1 shows a system that a jigger with two winding rollers, between the two plunge pools Contents are switched on, through which the web when wrapping or runs through when chewing. The web passes one when it is chewed out Suction slot, which is arranged on the winding arm just before the pressure roller, the against the pillar forming on a wagon outside the jigger is applied. Such jiggers are mostly used for dyeing textile webs. The order quantity of fleet is due to the fleet carrying capacity of Goods web limited.

Ein gattungsgemäßes Verfahren und eine solche Anlage gehen aus der WO 96/05349 hervor. In der WO 96/05349 ist eine Kleinveredlungsanlage in der Art eines erweiterten Jiggers wiedergegeben, bei dem alle Aggregate in einem dampfdichten Gehäuse angeordnet sind. Auch hier erfolgen ein Abquetschen nach einer ersten Naßbehandlung, eine weitere Naßbehandlung mit einer hohen Auftragsmenge. und ein Verweilen vor dem Aufkaulen. Allerdings steht die Kleinveredlungsanlage unter dem Aspekt der Dampfatmosphäre und fehlt es insbesondere an dem wichtigen Schritt der Penetrierung vor dem Verweilen.A generic method and such a system go out of the WO 96/05349. In WO 96/05349 a small finishing plant is in the kind of an extended jigger, in which all aggregates in a vapor-tight housing are arranged. This is also done here Squeezing after a first wet treatment, another wet treatment with a high order volume. and linger before chewing. However, the small finishing plant is under the aspect of Steam atmosphere and lacks in particular the important step of Penetration before lingering.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der dem Oberbegriff des Anspruchs 1 zugrundeliegenden Art und eine entsprechende Anlage dahingehend weiterzuentwickeln, daß die Penetration der Warenbahn durch die Flotte verbessert und die Bildung von Wassersäcken vermieden ist.The invention has for its object a method of Preamble of claim 1 underlying type and a corresponding System to further develop that the penetration of the web is improved by the fleet and the formation of water bags is avoided.
Diese Aufgabe wird verfahrensmäßig durch die in Anspruch 1 wiedergegebene Erfindung gelöst.This task is procedurally by the in claim 1 reproduced invention solved.
Nach der ersten Naßbehandlung wird die Warenbahn gleichmäßig entfeuchtet, z.B. durch Hindurchleiten durch ein Quetschwerk. Die Warenbahn wird hierdurch auf einer Restfeuchte von beispielsweise 60% bis 80% gebracht und ist danach aufnahmebereit für das Antragen weiterer Flotte, welches in einer hohen Auftragsmenge durch Tränken in einem Behälter mit verhältnismäßig geringem Flottenvolumen geschieht, so daß ein reine Addition ohne wesentlichen Flottenaustausch gegeben ist.After the first wet treatment, the web becomes even dehumidified, e.g. by passing through a crushing machine. The web is a residual moisture of 60% to 80%, for example and is then ready to accept further fleets, which is used in a large amount by soaking in a container relatively small fleet volume happens, so that a pure addition without significant fleet exchange.
Die stark mit Flotte, insbesondere mit außen anhaftender Flotte beladene Warenbahn wird nun in einem separaten Schritt, also nicht nur durch bloßes Einwirkenlassen auf einer gewissen Laufstrecke der Warenbahn, einer Penetrierung unterzogen, indem die Flotte von den Außenbereichen der Warenbahn in deren Inneres hineingedrückt oder hineingezogen wird.The strongly with fleet, especially with externally adhering fleet loaded web is now in a separate step, not just through just allowing it to act on a certain length of the web, one Penetrated by the fleet from the outside areas of the Material web is pressed or pulled inside.
In der Verweilphase vor dem Aufkaulen findet die Flotte Gelegenheit, sich in der Warenbahn zu verteilen, so daß beim anschließenden Aufkaulen die Neigung, von der Oberfläche der Warenbahn abzulaufen und sich im unteren Bereich der Kaule anzusammeln, wesentlich verringert ist.In the dwell phase before chewing, the fleet finds the opportunity to be distributed in the web so that when it is subsequently chewed up the tendency to run off the surface of the web and to accumulate lower area of the lobe is significantly reduced.
Bei der bevorzugten Ausführungsform des Verfahrens soll bei der zweiten Naßbehandlung eine Flottenmenge von mehr als 100%, bezogen auf das Flächengewicht der trockenen Warenbahn, aufgetragen werden (Anspruch 2), so daß insgesamt eine Flottenmenge von mehr als 160% oder 180% auf die Warenbahn aufgetragen worden sind und trotz der beim Penetrieren auftretenden Flottenverluste die Chemikalien einer hohen Flottenmenge auf der Warenbahn zur Wirkung kommen.In the preferred embodiment of the method, the second wet treatment a liquor amount of more than 100%, based on the weight per unit area of the dry web (Claim 2), so that a total of a fleet of more than 160% or 180% have been applied to the web and despite the Fleet losses that occur penetrate the chemicals of a high Fleet quantity on the web come into effect.
Wie bereits erwähnt, soll der Auftrag bei der zweiten Naßbehandlung im Additionsverfahrens ohne wesentlichen Flottenaustauch erfolgen (Anspruch 3).As already mentioned, the order for the second wet treatment in Addition process without substantial fleet replacement (claim 3).
Die Penetrierung soll bei der bevorzugten Ausführungsform durch Saugen vorgenommen werden (Anspruch 4).The penetration in the preferred embodiment is said to be through Sucking can be made (claim 4).
Ein wichtiges Merkmal ist die besondere Verweilbehandlung nach Anspruch 5, durch die die Flotte in der Warenbahn senkrecht zu ihrer Fläche hin- und hergetrieben wird und die Fasern der Warenbahn gut und gleichmäßig erreicht.An important feature is the special indwelling treatment after Claim 5, through which the fleet in the web perpendicular to its surface is driven back and forth and the fibers of the web well and achieved evenly.
Ein besonderes Anwendungsfeld des erfindungsgemäßen Verfahrens ist die KKV-Bleiche, bei welcher Baumwolle enthaltende oder aus Baumwolle bestehende Warenbahnen mit der Bleichflotte versehen und dann auf der Kaule viele Stunden verweilen gelassen werden, was die besondere Notwendigkeit der.Vermeidung Wassersäcken auf der Kaule sinnfällig werden läßt. Bei der ersten Naßbehandlung wird die Warenbahn mit Bleichflotte oder verdünnter Bleichflotte versehen, worauf bei der zweiten Naßbehandlung die Addition weiterer Bleichflotte erfolgt.A particular field of application of the method according to the invention is the KKV bleach, in which cotton contains or from cotton Provide existing webs with the bleaching liquor and then on the Cheek can be left for many hours, what is special The need to avoid water bags on the hoof become obvious leaves. During the first wet treatment, the web is bleached or dilute bleaching liquor, whereupon the second wet treatment Additional bleaching liquors are added.
In den Ansprüchen 7 und 8 sind die vorrichtungsmäßigen Aspekte der
Erfindung wiedergegeben.In
In der Zeichnung ist ein Ausführungseispiel der Erfindung schematisch dargestellt.In the drawing, an exemplary embodiment of the invention is schematic shown.
Die Rollenanordnung in der turmartigen Verweilzone nach Anspruch 10
ist für sich genommen aus der EP 517 713 B1 bekannt, wo sie allerdings in
einer anderen Funktion, nämlich im Eingangsbereich eines Dämpfers
vorgesehen ist.
Die in Fig. 1 als Ganzes mit 100 bezeichnete Anlage dient zur
Ausführung einer KKV-Bleiche und wird von einer Baumwolle enthaltenden
oder aus Baumwolle bestehenden Warenbahn 10 im Pfeilsinne von rechts
nach links durchlaufen. Rechts außerhalb der Darstellung der Fig. 1 erfährt die
Warenbahn 10 eine erste Naßbehandlung mit einer Bleichflotte. Die
Warenbahn 10 wird sodann in einem Quetschwerk 1 gleichmäßig auf eine
Restfeuchte von etwa 60% bis 80% entfeuchtet. Nach dem Passieren eines
Kompensators 2 gelangt die Warenbahn 10 in ein Aggregat 3, in welchem
eine zweite Naßbehandlung mit Bleichflotte stattfindet. Das Aggregat 3 umfaßt
einen Trog 4 für die Bleichflotte 5, in welchem eine horizontale Umlenkrolle 6
angeordnet ist. Die Warenbahn 10 passiert nach dem Kompensator 2 eine mit
Abstand oberhalb des Troges 4 angeordnete Umlenkrolle 7, läuft von dieser
etwa vertikal nach unten über die Umlenkrolle 6 und dann wieder vertikal nach
oben über eine in
gleicher Höhe neben der Umlenkrolle 7 angeordnete Umlenkrolle
8.1 designated as a whole in Fig. 1 is used for
Execution of a KKV bleach and is made of a cotton containing
or made of
Das Volumen des Troges 4 ist bewußt kleingehalten.
Der Trog 4 umschließt die Warenbahn 10 und die Umlenkrolle
6 so dicht, wie es konstruktiv durchführbar ist. Auch ist
die Füllstandshöhe der Bleichflotte 5 gering, so daß ihr
Spiegel nur etwa um den Durchmesser der Umlenkrolle 6 über
deren oberen Scheitel steht. Die Warenbahn 10 soll in dem
Trog 4 lediglich an der Oberfläche eine Flottenaddition
erfahren, ohne daß in dem Trog 4 nennenswerte Austauschreaktionen
zwischen der Warenbahn 10 und der Bleichflotte 5
stattfinden.The volume of the trough 4 is deliberately kept small.
The trough 4 encloses the
Nach dem Passieren der Umlenkrolle 8 legt die Warenbahn
10 zwischen den Umlenkrollen 8 und 8' einen etwa
horizontalen Abschnitt 10' zurück und läuft dabei über
eine Sauge 9 mit einem Saugschlitz 11, der sich über die
Breite der Warenbahn 10 erstreckt und an welchem die oberflächlich
vorhandene Bleichflotte aus den Trog 4 in das
Innere der Warenbahn 10 hineingesaugt wird.After passing the
Das von der Sauge 9 abgesaugte Gemisch aus Bleichflotte
und Luft gelangt über die Leitung 12 in einen Separator
13, an den über eine Leitung 14 eine Vakuumpumpe 15
angeschlossen ist, die die Saugwirkung erzeugt. Die in dem
Separator 13 abgetrennte Bleichflotte wird von einer Pumpe
16 über eine Leitung 17 wieder in den Trog 4 zurückgeführt.
Die Zuleitung 18 mit dem steuerbaren Ventil 19
dient dem Nachsetzen von Bleichflotte, um in den Trog 4
ein konstantes Niveau aufrechtzuerhalten.The mixture of bleach liquor sucked off by the suction 9
and air passes through line 12 into a
Nach dem Verlassen der horizontalen Strecke 10' passiert
die Warenbahn 10 eine turmartige Verweilstrecke 20,
in die die Warenbahn 10 von unten einläuft. Die Verweilstrecke
umfaßt zwei Gruppen 27,28 von untereinander gleichen,
einander parallelen, horizontalen, vertikal übereinander
angeordneten Umlenkrollen 29, über die die Warenbahn
10 im Zickzack in im wesentlichen horizontalen Schleifen
40 von unten nach oben geführt ist. Unmittelbar übereinander
gelegene Umlenkrollen 29 bilden keinen Quetschspalt,
sondern lassen die Warenbahn 10 quetschfrei hindurch. Der
vertikale Abstand d (Fig. 2) zweier vertikal übereinander
angeordneter Umlenkrollen 29 ist kleiner als der Durchmesser
D einer Umlenkrolle. Außerdem sind die Achsen der
Umlenkrollen 29 in einer Gruppe, z.B. 28, in der Höhe
mittig zu den Achsen der Umlenkrollen 29 der jeweils anderen
Gruppe, z.B. 27, angeordnet. Dadurch ergibt sich die
in Fig. 2 dargestellte Warenbahnführung bei der die geraden
Warenbahnabschnitte 10" zwischen den Umlenkrollen 29
ein leichtes Gefälle aufweisen, welches in Fig. 2 durch
den Winkel 31 angedeutet ist, der in dem dargestellten
Ausführungsbeispiel 7° beträgt und etwa 5° bis 10° betragen
kann. Vor den Umlenkrollen 29, auf die die Warenbahnabschnitte
10" zulaufen, bilden sich kleine Wülste 32 an
Behandlungsflotte (Fig. 2), die beim Umlauf um die dortige
Umlenkrolle 29 in die Warenbahn 10 hineingedrückt werden,
wodurch eine Penetrierung der ganzen Warenbahn 10 mit der
in dem Aggregat 3 außen angetragenen Behandlungsflotte 5
stattfindet. Diese Penetrierung wird dadurch gefördert,
daß die Zentrifugalkraft an den Umlenkrollen 29 die
Bleichflotte bei der Gruppe 27 in der entgegengesetzten
Richtung, senkrecht zur Fläche der Warenbahn 10 gesehen,
durch diese zu treiben sucht wie bei der Gruppe 28, so daß
also die Bleichflotte beim Passieren der turmartigen Verweilzone
20 in der Warenbahn 10 hin- und herverlagert
wird, so daß es zu einer wirkungsvollen Umströmung der
Fasern der Warenbahn 10 mit Bleichflotte kommt.After leaving the horizontal route 10 'happens
the web 10 a tower-
Durch die im wesentlichen horizontale Warenbahnführung
in der Verweilzone 20 werden ein Herablaufen der
Flotte an der Warenbahn 10 und Tropferscheinungen vermieden,
die sonst zu Ungleichmäßigkeiten des Behandlungsausfalls
führen könnte.Due to the essentially horizontal web guidance
in the
Nach dem Verlassen der Verweilzone 20 bzw. der obersten
Umlenkrolle 29' der Gruppe 27 passiert die Warenbahn
10 die tiefer gelegene Umlenkrolle 21 einer als Ganzes mit
30 bezeichneten Wickeleinrichtung. Die Wickeleinrichtung
30 besitzt zu beiden Seiten der Warenbahn Wickelarme 22,
zwischen denen die Umlenkrolle 21 an einem Ende der Wikkelarme
22 in der Nähe der dortigen Schwenkachse 23 derselben
gelagert ist. Die Warenbahn 10 verläuft entlang der
Wickelarme 22 bis zu einer am freien Ende der Wickelarme
22 angeordneten angetriebenen Andrückwalze 24, von der die
Warenbahn 10 auf eine Kaule 25 übergeht, die auf einem
Kaulenwagen 26 am Ende der Anlage aufgewickelt wird.After leaving the
Durch das Absaugen der Warenbahn 10 nach dem Passieren
des Troges 4 und das Verweilen in der Verweilzone 20
