Description

Die Efindung betrifft ein Verfahren und eine Vorrichtung zum kontinuierlichen Behandeln von bahnförmigem Textilgut, das in vertikalen Schlaufen mittels Querstäbe horizontal durch eine Behandlungsflüssigkeit, insbesondere heiße Flotte, transportiert wird und die Bildung der Schlaufen durch eine vertikale Strömung erfolgt, wobei die Schlaufenbildung, die Erhaltung der gebildeten Schlaufe, deren Formstabilität sowie deren horizontale Bewegung durch in der unteren Schlaufenkrümmung liegende Querstäbe, die sich in Nähe des Behälterbodens von der Textilbahneintrittsseite zur-ausgangsseite bewegen, und durch die zwischen den Querstäben aufwärts gerichtete Strömung erfolgt.The invention relates to a method and a device for the continuous treatment of web-like textile material, which is transported in vertical loops by means of cross bars horizontally through a treatment liquid, in particular hot liquor, and the formation of the loops takes place by a vertical flow, the loop formation, the preservation of the formed loop, its dimensional stability and its horizontal movement by transverse bars located in the lower loop curvature, which move in the vicinity of the container bottom from the textile web entry side to the exit side, and by the upward flow between the cross bars.

Durch die deutsche Fachzeitschrift "Melliand-Textilberichte, 2/1978, S. 143-146" ist eine Vorrichtung der eingangs genannten Art bekannt, bei der die Schlaufen um im oberen Abschnitt des Behandlungsbehälters horizontal geführte Rollen oder Stege geschlungen sind. Die Bildung der Schlaufen und die Erhaltung der Formstabilität erfolgt hierbei durch eine gegen den natürlichen Auftrieb der Textilschlaufen in der Flüssigkeit gerichtete Flüssigkeitsströmung, wobei die Flüssigkeit über die Breite und Länge des Bodens des Behandlungsbehälters abgesogen wird. Die horizontale Querbewegung der Schlaufen erfolgt durch die Rollen und Stege. Um senkrechte Schlaufen beim Ziehen derselben mittels der Rollen oder Stege im oberen Behälterabschnitt zu erreichen, muß eine stark abwärts gerichtete Strömung benutzt werden.The German trade magazine "Melliand-Textilberichte, 2/1978, pp. 143-146" discloses a device of the type mentioned in the introduction, in which the loops are looped around rollers or webs which are guided horizontally in the upper section of the treatment container. The formation of the loops and the maintenance of the dimensional stability is carried out here by a liquid flow directed against the natural buoyancy of the textile loops in the liquid, the liquid being drawn off over the width and length of the bottom of the treatment container. The horizontal transverse movement of the loops takes place through the rollers and webs. In order to achieve vertical loops when pulling them by means of the rollers or webs in the upper container section, a strongly downward flow must be used.

Die US-A-2 261 770, die den Gattungsbegriff des Hauptanspruches bestimmt, zeigt und beschreibt ein endloses Kettenpaar mit Querstäben, die den Transport der Schlaufen durch die Behandlungsflüssigkeit bewirken. Hierbei können die Schlaufen nur kurz sein; die Geschwindigkeit, mit der die Schlaufen durch die Behandlungsflüssigkeit bewegt werden, ist mit zunehmender Schlaufenlänge geringer zu wählen.US-A-2 261 770, which defines the preamble of the main claim, shows and describes an endless pair of chains with crossbars which effect the transport of the loops through the treatment liquid. The loops can only be short; the speed at which the loops are moved through the treatment liquid should be chosen to be lower with increasing loop length.

Der Erfindung liegt daher die Aufgabe zugrunde, mit möglichst geringem Energiebedarf eine hohe behandlungsgeschwindigkeit zu erreichen und dabei eine hohe Schlaufenlänge sowie knick- und faltenfreie, weitgehend senkrechte Schlaufen zu erzielen. Insgesamt soll hierbei die zur Anwendung gelangende Vorrichtung einen Einfachen Aufbau besitzen.The invention is therefore based on the object of achieving a high treatment speed with the lowest possible energy requirement and at the same time achieving a long loop length and kink-free and wrinkle-free, largely vertical loops. Overall, the device used here should have a simple structure.

Zur lösung dieser Aufgabe sieht die Erfindung ein Verfahren der eingangs genannten Gattung vor, bei dem zur Unterstützung der horizontalen Bewegung und der Erhaltung der vertikalen Stellung der Schlaufen eine horizontale Querströmung der Behandlungsflüssigkeit erzeugt wird.To achieve this object, the invention provides a method of the type mentioned, in which a horizontal transverse flow of the treatment liquid is generated to support the horizontal movement and to maintain the vertical position of the loops.

Vorzugsweise kann die horizontale Strömung durch im Kreislauf mit einer Pumpe umgewältze Behandlungsflüssigkeit erzeugt werden, wie auch die horizontale Strömung über annähernd die Höhe und Breite der Schlaufen erzeugt wird. Die Unteransprüche 4 und 6 bis 10 beinhalten vorteilhafte Merkmale zur Durchführung des Verfahrens und zur Ausbildung der Vorrichtung.Preferably, the horizontal flow can be generated by treatment liquid circulated in the circuit with a pump, as can the horizontal flow over approximately the height and width of the loops. The sub-claims 4 and 6 to 10 contain advantageous features for performing the method and for forming the device.

Der Vorteil des Verfahrens und der Vorrichtung nach der Erfindung offenbart sich nicht nur darin, daß die Schlaufen selbst bei großer Länge keine Schrägstellung erfahren und damit Gefahr laufen, sich aufeinander zu legen, wenn die Querstäbe im unteren Behälterabschnitt von der Eingangs- aur Ausgangsseite bewegt werden. Während der Fußabschnitt der Schlaufen durch die Querstäbe der endlosen Doppelkette durch die Flüssigkeit zur Ausgangsseite gebracht wird, wird der mittlere und obere Schlaufenabschnitt durch die zusätzliche horizontale Querströmung bewegt, die vorzugsweise variierbar ist, so daß es in der Tat gelingt, die Schlaufen senkrecht und formstabil durch die Behandlungsflüssigkeit zu bewegen. - Die horizontale Querbewegung der Schlaufen gestaltet sich einfach und energiesparend, wenn die Aufwärtsströmung, wie aus der DE-OS 2 207 964, S. 3, Abs. 1, bekannt, eine Luft, oder Dampfströmung ist, die zur Bildung der Schlaufen selbst weiterhin außer einer Mammutpumpenwirkung auf die Flüssigkeit noch eine Luft- oder Gasblase in der oberen Schlaufenkrümmung entstehen läßt, die das horizontale Bewegen der Schlaufen erleichtert. Die Querströmung saugt oder drückt das Luft- oder Dampfpolster in den Oberen Krümmungen der Schlaufe mit diesen zur Ausgangsseite.The advantage of the method and the device according to the invention is not only evident in the fact that the loops are not inclined, even at great lengths, and thus run the risk of lying on top of one another if the cross bars in the lower container section are moved from the entrance to the exit side . While the foot section of the loops is brought through the liquid to the exit side by the cross bars of the endless double chain, the middle and upper loop sections are moved by the additional horizontal cross flow, which is preferably variable, so that the loops can indeed be vertical and dimensionally stable to move through the treatment liquid. - The horizontal transverse movement of the loops is simple and energy-saving if the upward flow, as known from DE-OS 2 207 964, p. 3, paragraph 1, is an air or steam flow that continues to form the loops themselves In addition to a mammoth pump effect on the liquid, an air or gas bubble can be created in the upper loop curvature, which facilitates the horizontal movement of the loops. The cross flow sucks or pushes the air or steam cushion in the upper curvatures of the loop with these towards the exit side.

Die bei dem erfindungsgemäßen Verfahren zur Anwendung gelangende Vorrichtung weist eine Behälter G auf, der dampfdicht geschlossen ist und mit einer Behandlungsflüssigkeit B gefüllt ist, deren Spiegel S bis in Nähe des oberen Behälterrandes reicht. Der Behälter G weist an seiner Vorderwand V ein Wasserchloß 1 auf, dem an der Rückwand R des Behälters ein Kaltwasserschloß 2 gegenüberliegt. Die zu behandelnde Textilbahn T wird durch das Zugwalzenpaar 3 in die Behandlungsflüssigkeit B eingezogen und einer Schlaufenbildungsdüse 4 zugeführt, deren Strahl senkrecht oder annähernd senkrecht nach oben gerichtet ist.The device used in the method according to the invention has a container G which is closed in a vapor-tight manner and is filled with a treatment liquid B, the level S of which extends to near the upper edge of the container. The container G has on its front wall V a water lock 1, which is opposite a cold water lock 2 on the rear wall R of the container. The to be acting textile web T is drawn into the treatment liquid B by the pair of pull rollers 3 and fed to a loop formation nozzle 4, the jet of which is directed vertically or approximately vertically upwards.

In der Nähe der Vorderwand V, der Rückwand R sowie im unteren Abschnitt des Behälters sowie in Nähe des Spiegels S der Behandlungsflüssigkeit ist eine Rollenkette 5 geführt, die aus im Abstand voneinander gelegenen Einzelketten und zwischen diesen sich erstreckenden Stegen oder Transportrollen 6 besteht. Die Kette 5 ist um Umlenkrollen 7-7e etwa auf einer Rechteckbahn geführt, wobei die beiden Einzelketten der Rollenkette 5 einen größeren Abstand als die Breite der Textilbahn aufweisen. - Die Anordnung und Führung der Rollenkette 5 ist derart, dass die sich entgegen dem Uhrzeigersinn bewegende Kette in Bewegungsrichtung hinter der Schlaufenbildungsdüse 4 den Abstand der Transportstangen auf 1/10 verringert, d.h. z.B. den Abstand der Transportstange von 500 mm auf 50 mm reduziert. Hierdurch werden nach unten durchhängende Schleifenabschnitte oder Kettenschlaufen 11 gebildet, deren Länge etwa der Hälfte des Abstandes der Kettenstege oder Transportrollen 6 entspricht, d.h. in oben gegebenem Beispiel ist die Länge der Kettenschlaufen 11 bei einem Abstand der Stege oder Transportrollen von 500 mm = 250 mm. - Die Kette 5 wird durch die Umlenkkettenräder 7b und 7d angetrieben. Die Schlaufenhöhe, die dem Wärmeinheit des Behälters wiedergibt, kann durch ein stufenloses Regelgetriebe zwischen dem Zugwalzenpaar 3 und den Kettenrädern 7b und 7d verändert werden.In the vicinity of the front wall V, the rear wall R and in the lower section of the container and in the vicinity of the level S of the treatment liquid, a roller chain 5 is guided, which consists of individual chains spaced apart from one another and webs or transport rollers 6 extending between them. The chain 5 is guided around deflection rollers 7-7e approximately on a rectangular path, the two individual chains of the roller chain 5 being at a greater distance than the width of the textile path. The arrangement and guidance of the roller chain 5 is such that the counterclockwise chain in the direction of movement behind the loop formation nozzle 4 reduces the distance of the transport rods to 1/10, i.e. e.g. reduced the distance of the transport bar from 500 mm to 50 mm. As a result, loop sections or chain loops 11 sagging downward are formed, the length of which corresponds to approximately half the distance between the chain stays or transport rollers 6, i.e. In the example given above, the length of the chain loops 11 is at a spacing of the webs or transport rollers of 500 mm = 250 mm. - The chain 5 is driven by the deflection sprockets 7b and 7d. The loop height, which represents the heating unit of the container, can be changed by means of a continuously variable control gear between the pair of pull rollers 3 and the chain wheels 7b and 7d.

Oberhalb des Bodens GB des Behälters G ist ein Rost oder eine aus zwei im Abstand voneinander gehaltenen Schienen gebildete Auflage 9 angeordnet, auf denen die querschnittsrunden Stege oder Transportrollen abgleiten oder abrollen. Hierzu ist die durch den Rost oder die Doppelschiene gebildete Stangenauflage von der Einlaufseite der Textilbahn zur Auslaufseite hin geneigt. Durch diese Neigung wird, wie untenstehend noch näher beschrieben wird, die horizontale Bewegung des Textilbahnschlaufenpaketes P in Fig. 1 von der links nach rechts, d.h. von der Wareneinlaß- zur Warenauslaßseite, bewirke.Arranged above the bottom GB of the container G is a grate or a support 9 formed from two spaced-apart rails on which the cross-sectional webs or transport rollers slide or roll off. For this purpose, the bar support formed by the grate or the double rail is inclined from the inlet side of the textile web to the outlet side. This inclination, as will be described in more detail below, causes the horizontal movement of the textile web loop package P in Fig. 1 from left to right, i.e. from the goods inlet to the goods outlet side.

Während die Schlaufenbildungsdüse 4 für das Aufschwimmen der Textilbahn und die Bildung der Schlaufen 10 sorgt, werden die in ihrer vollen Höhe entstandenen Schlaufen 12, die das Schlaufenpaket P entstehen lassen, in ihrer Lage und formstabil dadurch gehalten, dass einerseits das untere Ende der Schlaufen durch die Stege oder Transportrollen gehalten wird, andererseits zwischen den Stegen oder Transportrollen eine Auftriebsunterstützung in Form einer aero- und/oder hydrodynamischen Strömung vorgesehen ist. Diese besteht aus mehreren im Abstand voneinander an einer schrägen Traverse L angeordneten Mänteln 14, deren Seitenwände einen Düsenschlitz 15 bilden, der überdie Breite des Behälters G reicht. An der Traverse L sind in Vorschubrichtung des Schlaufenpaketes P zwischen den Düsenschlitzen 15 mit Düsen oder Öffnungen versehene Rohre 16 angebracht, aus denen Luft oder Dampf senkrecht nach oben austritt.While the loop formation nozzle 4 provides for the floating of the textile web and the formation of the loops 10, the loops 12, which are created in their full height and allow the loop package P to be created, are held in their position and are dimensionally stable in that, on the one hand, the lower end of the loops passes through the webs or transport rollers are held, on the other hand, buoyancy support in the form of an aero- and / or hydrodynamic flow is provided between the webs or transport rollers. This consists of a plurality of jackets 14 arranged at a distance from one another on an inclined cross member L, the side walls of which form a nozzle slot 15 which extends across the width of the container G. Tubes 16 with nozzles or openings are provided on the crossbar L in the feed direction of the loop package P between the nozzle slots 15, from which air or steam emerges vertically upwards.

In den Mänteln 14, die eine nach unten offene untere Kammer 30 bilden, ist eine Rohr 31 mit Austrittsdüsen 33 angeordnet, aus denen Luft, Dampf, oder ein Gas austreten kann und die somit zwischen den Wänden 35 den Mäntel 14 einen Ejektor 34 bilden. Hierdurch wird zwischen den Transportstagen 6 eine aufwärsgerichtete Strömung, wie sie in Fig. 3 mit der Bezugsziffer 32 wiedergegeben ist, erzeugt, Hierbei 'steigen Blasen 32a in die Schlaufen 12 auf, an deren oberen Ende ein formstabiler Schlaufenkopf 29 gebildet wird.In the jackets 14, which form a lower chamber 30 which is open at the bottom, a tube 31 is arranged with outlet nozzles 33, from which air, steam or a gas can escape and which thus form an ejector 34 between the walls 35 of the jackets 14. As a result, a warm-up flow, as shown in FIG. 3 with the reference number 32, is generated between the transport days 6. Here, bubbles 32a rise into the loops 12, at the upper end of which a dimensionally stable loop head 29 is formed.

Der Transport des Schlaufenpaketes P wird durch eine horizontale Strömung des Behandlungsflüssigkeit unterstützt, die durch aus der Wand 18 eines Verteilerkastens K an der Eintrittsseite des Behälters G austretende Flotte entsteht. Die Flotte tritt horizontal reihen- oder flächenmäßig aus den Öffnungen 18a der Wand 18 aus und schiebt das Schlaufenpaket P vor sich her bis an das Austrittsende des Behälters, wo eine gleichgeartete Wande 17 eines Kastens K1 vorgesehen ist, durch deren Eintrittsöffnungen 17a die Flotte abgesogen wird, die im Kreislauf über eine Pumpe gegebenenfalls auch über einen Wärmeaustauscher wieder dem Kasten K zugeführt wird. Am Austrittsende der Textilbahn aus dem Paket P ist eine Pendelführer 13 angeordnet, der die Geschwindigkeit eines Abzugswerkes oder eines Quetschwerkes am Gehäuseauslaß regelt.The transport of the loop packet P is supported by a horizontal flow of the treatment liquid, which is created by the liquor emerging from the wall 18 of a distribution box K on the inlet side of the container G. The liquor emerges horizontally in rows or areas from the openings 18a of the wall 18 and pushes the loop package P in front of it to the outlet end of the container, where a similar wall 17 of a box K 1 is provided, through the inlet openings 17a of which the liquor is drawn off is, which is supplied to the box K in the circuit via a pump, possibly also via a heat exchanger. At the exit end of the textile web from the package P, a shuttle guide 13 is arranged, which regulates the speed of a take-off unit or a squeezing unit at the housing outlet.

Damit die Luft- oder Dampfblasen zwischen den Stegen oder Transportrollen 6 in die Schlaufen 12 gelangen können, werden die Stege oder Rollen 6 durch nicht dargestellte Abstandscheiben an den Steg- oder Rollenenden auf Abstand gehalten, während sie auf der Auflage 9 schräg abwärts gleiten oder rollen.So that the air or steam bubbles between the webs or transport rollers 6 can get into the loops 12, the webs or rollers 6 are kept at a distance by spacer disks (not shown) at the web or roller ends while they slide or roll obliquely downwards on the support 9 .

Der Behälter G weist an seinem oberen Abschnitt Sichtfenster 20 auf, durch die das Schlaufenpaket im Inneren des Gehäuses beobachtet werden kann. Ein Schwimmerventil und der Überlauf 21 sorgen für ein gleichbleibendes Flottenniveau. - Der einstellbare Druckwächter 22 mit Abzugskamin 23 garantiert eine konstante Flottentemperatur in dem Behälter. Die Deckenplatten 24 liegen in einem Wasserring 25, der als Dampfsperre dient.At its upper section, the container G has viewing windows 20 through which the loop package in the interior of the housing can be observed. A float valve and the overflow 21 ensure a constant fleet level. - The adjustable pressure switch 22 with chimney 23 guarantees a constant liquor temperature in the container. The ceiling panels 24 lie in a water ring 25, which serves as a vapor barrier.

Wie Fig. 1, erkennen läßt, laufen die Stege oder Rollen 6 mit ihren seitlichen gall'schen Ketten in Bewegungsrichtung hinter dem Umlenkrad 7b gegen die Textilbahn und nehmen diese unter Bildung der ersten Schlaufe durch die Düse 4 mit. Danach reihen sich die Stege oder Rollen unter Einhaltung des Abstandes X (Fig. 3) auf der Auflage 9 hintereinander, so dass die jeweiligen unteren Kettenschlaufen 11 1 gebildet werden, die am Ende der Auflage 9 wieder aufgelöst werden.As can be seen in FIG. 1, the webs or rollers 6 run with their lateral Gall chains in the direction of movement behind the deflection wheel 7b against the textile web and take it through the nozzle 4 to form the first loop. The webs or rollers then line up on the support 9 while maintaining the distance X (FIG. 3), so that the respective lower chain loops 11 1 are formed, which at the end of the support 9 to be dissolved again.

Aus Vorstehendem ist erkennbar, dass die Stege oder Rollen 6 mit den jeweils an ihnen befestigten Kettenschlaufen 11 spezifisch so schwer sind, dass die Stege oder Rollen in der Flüssigkeit auch gegen die Auftriebsströmung absinken, d.h. auf der Auflage 9 abrollen oder abgleiten und dabei in der unteren Krümmung der Schlaufe SCH liegen.From the above it can be seen that the webs or rollers 6 with the chain loops 11 attached to them are specifically so heavy that the webs or rollers in the liquid also sink against the buoyancy flow, i.e. roll or slide on the pad 9 and lie in the lower curvature of the loop SCH.

Bei der Ausführungsform nach Fig. 6 ist dies auch der Fall. Hier rollen oder gleiten die Rollen 50 wiederum auf einer unteren geneigten Auflage 51 von der Eintrittsseite zur Austrittsseite des Behälters mit der Badflüssigkeit B. Am Ende der Auflage 51 ist ein senkrechtes Hebewerk 52 mit Mitnehmern 53 angeordnet, durch das die die Auflage 51 verlassenden Rollen 50 nach oben mitgenommen und auf eine Auflage 54 aufgegeben werden, die entgegengesetzt zur Auflage 51 geneigt ist und auf der die Rollen 50 in Fig. 6 nach links abrollen. Am vorderen Ende 54a fällt in bestimmtem Takt eine Rolle 50a auf den der Umlenkrolle 55 benachbarten Abschnitt 56 der Textilbahn. Da am Anfang 51 a der Auflage 51 durch die Düse 57 eine starke Aufwärtsströmung erzeugt wird, kann die Rolle 50a in der Flüssigkeit bis auf die Auflage 51 absinken und dort abwärts rollen, während die gebildete Schlaufe erhalten bleibt und wie bei der Ausführungsform nach Fig. 1 nach rechts bewegt wird. Die Textilgutbahn T verläßt wie auch in Fig. 1 den Behandlungsbehälter über die Rollen 58, 59, 60, wobei die letzte Schlaufe Sch' durch die Rolle 61 eingesogen wird.In the embodiment according to FIG. 6, this is also the case. Here the rollers 50 in turn roll or slide on a lower inclined support 51 from the entry side to the exit side of the container with the bath liquid B. At the end of the support 51 there is a vertical elevator 52 with drivers 53 through which the rollers 50 leaving the support 51 taken up and placed on a support 54 which is inclined opposite to the support 51 and on which the rollers 50 roll to the left in Fig. 6. At the front end 54a, a roller 50a falls on the section 56 of the textile web adjacent to the deflection roller 55 in a defined cycle. Since at the beginning 51 a of the pad 51 a strong upward flow is generated by the nozzle 57, the roller 50 a in the liquid can sink to the pad 51 and roll down there, while the loop formed is retained and, as in the embodiment according to FIG. 1 is moved to the right. As in FIG. 1, the textile material web T leaves the treatment container via the rollers 58, 59, 60, the last loop Sch 'being drawn in by the roller 61.
