Abstract

The invention relates to the discontinuous wet treatment of a hank of fabric in at least one cycle of the fabric through a treatment compartment. In order to achieve a rapid and reliable wet treatment with a relatively simple construction, the treatment compartment is divided into two treatment chambers which lie parallel adjacent to one another, so that with each circulation of the fabric two sections of fabric running parallel to one another are treated simultaneously in two similar treatment chambers of the same treatment compartment which serve for the same type of treatment.

Description

Die Erfindung betrifft ein Verfahren zur diskontinuierlichen Naßbehandlung einer strangförmigen Warenbahn entsprechend dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung zur diskontinuierlichen Naßbehandlung einer strangförmigen Warenbahn gemäß dem Oberbegriff des Anspruches 3.The invention relates to a method for discontinuous Wet treatment of a strand-like web according to the preamble of claim 1 as well a device for discontinuous wet treatment a strand-shaped web according to the preamble of claim 3.

In einer solchen Naßbehandlung werden textile Wirk- und Webwaren in Strangform in wenigstens einem Umlauf durch ein Behandlungsabteil hindurchtransportiert und dabei vor allem gefärbt, gebleicht oder gewaschen.In such a wet treatment, textile active and Woven goods in strand form in at least one circulation transported a treatment compartment and thereby especially dyed, bleached or washed.

Bei diesem allgemein aus der Praxis bekannten Stand der Technik wird die Ware bzw. Warenbahn wenigstens einmal in ihrer gesamten Länge durch das Behandlungsabteil hindurchgefahren, um mit frischer Flotte, Chemikalien oder auch notwendigen mechanischen Einwirkungen in Kontakt zu kommen und um auf diese Weise den erforderlichen Stoff- bzw. Flottenaustausch herbeizuführen. Man ist dabei bestrebt, mit relativ hohen Umlaufgeschwindigkeiten zu arbeiten.In this generally known from practice Technology is the goods or web at least once in its entire length through the treatment compartment drove through with fresh liquor, chemicals or also necessary mechanical influences in contact to come and in this way the necessary To bring about material or fleet exchange. Man strives to achieve relatively high speeds to work.

Hohe Umlaufgeschwindigkeiten lassen zwar ein relativ geringes Flottenverhältnis (das Verhältnis Warenmenge zu Flottenmenge) zu, wodurch Behandlungszeiten, Flottenverbrauch und Energieeinsatz relativ niedrig gehalten werden können. Hohe Umlaufgeschwindigkeiten haben aber auch erhebliche Nachteile: Es ergibt sich vielfach ein unsicherer Warenbahnlauf (beispielsweise durch Verknotungen oder dgl.); hohe Beschleunigungen der Warenbahn führen vielfach zu unerwünscht großem Längszug; grundsätzliche Transportprobleme treten auch bei extrem leichten und extrem schweren Waren auf; durch Einflüsse von Schaum und Chemikalien kann ein unerwünschter Schlupf beim Warentransport auftreten; ferner erfährt die Oberfläche der Warenbahn vielfach eine unerwünschte mechanische Aufrauhung.High speeds of circulation allow a relative low fleet ratio (the ratio of the quantity of goods to fleet amount), thereby reducing treatment times, fleet consumption and energy consumption kept relatively low can be. Have high circulation speeds but also considerable disadvantages: there are many an unsafe web run (for example due to knots or the like); high acceleration of the web often lead to undesirably large longitudinal pull; basic transportation problems also occur with extreme light and extremely heavy goods; through influences of foam and chemicals can be an undesirable Slip occurs during goods transport; further learns the surface of the web is often an undesirable one mechanical roughening.

Man hat zwar auch bereits versucht, einige der zuvor aufgezeigten Nachteile dadurch zu beheben, daß der Transport der Warenbahn für deren Umlauf durch Einblasen von Luft oder inertem Gas und gleichzeitigem Einspeisen von Behandlungsflotte unterstützt wird. Hierbei wird mit besonders hohen Umlaufgeschwindigkeiten gearbeitet. Der maschinentechnische Aufwand ist jedoch auch besonders hoch.You have already tried some of the previous ones to remedy the disadvantages that the Transport of the material web for its circulation by blowing of air or inert gas and simultaneous feeding is supported by the treatment fleet. Here is used at particularly high speeds. The mechanical engineering effort is also, however especially high.

Aus der EP-A-419 825 ist eine Vorrichtung bekannt, in der eine strangförmige Warenbahn kontinuierlich naßbehandelt werden soll. Die Warenbahn wird dabei durch eine offensichtlich größere Anzahl von Naßbehandlungskammern nacheinander (kontinuierlich) hindurchtransportiert, bei denen es sich in der Regel um deutlich voneinander abgegrenzte einzelne Behandlungsabteile mit im wesentlichen rechteckigem Grundriß handelt. Ein wesentlicher Gedanke dieser bekannten Ausführung ist darin zu sehen, daß die über den Einlaufenden der einzelnen Behandlungskammern angeordneten, rotierend antreibbaren Transportorgane je einen in seiner Antriebsdrehzahl veränderbaren Antriebsmotor besitzen und daß jeder einzelnen Behandlungskammer eine eigene Füllstandsüberchungseinrichtung zugeordnet ist, durch die der momentane Füllungsstand jeder Behandlungskammer überwacht und gesteuert werden kann, d.h. die hintereinandergeschalteten Behandlungskammern sind so ausgestattet, daß beispielsweise unabhängig von der gerade gegebenen Produktionsgeschwindigkeit der Warenbahnen praktisch der gesamte Bereich von 0 bis maximal als Warenbahn-Transportgeschwindigkeit durch jede einzelne Kammer ausgenutzt werden kann. Dementsprechend sollte dort auch dafür gesorgt werden, daß selbst bei stark schwankenden Warenbahnqualitäten vorgewählte Warenfüllungen in den einzelnen Behandlungskammern auch ohne manuellen Eingriff sehr genau eingehalten werden können.From EP-A-419 825 a device is known in which continuously wet-treated a strand-shaped material web shall be. The web is thereby an obviously larger number of wet treatment chambers transported one after the other (continuously), which are usually clearly different from each other delimited individual treatment compartments with in essentially rectangular plan. An essential one The thought of this well-known version is too see that over the inlet ends of the individual treatment chambers arranged, rotatably driven Transport organs each in its drive speed possess changeable drive motor and that each one Treatment chamber its own level monitoring device assigned by which the current The filling level of each treatment chamber is monitored and can be controlled, i.e. the cascaded Treatment chambers are equipped so that for example, regardless of the just given Production speed of the webs practical the entire range from 0 to maximum as the web transport speed through every single chamber can be exploited. Accordingly, there should be also be ensured that even with strongly fluctuating Material qualities of pre-selected goods in the individual treatment chambers even without manual Intervention can be followed very precisely.

Aus der EP-A-0 075 650 (Oberbegriff den unabhängigen Ansprüche 1 und 3) ist ferner eine Vorrichtung zur Naßbehandlung einer strangförmigen Textilgut-Warenbahn bekannt. In dieser Behandlungsvorrichtung ist eine größere Anzahl von Behandlungskammern, d.h. in den beschriebenen Ausführungsbeispielen sind acht Behandlungskammern derart hintereinander bzw. nebeneinander angeordnet, daß sie von einer zu behandelnden Warenbahn insgesamt etwa schraubenlinienförmig durchlaufen werden, was bevorzugt kontinuierlich geschieht, ggf. aber auch diskontinuierlich erfolgen kann, wobei jede Kammer die gleiche oder unterschiedliche Flotte enthalten kann. Falls bei dieser bekannten Ausführung diskontinuierlich gearbeitet wird, werden zunächst nacheinander alle Kammern und dabei die ganze Vorrichtung schraubenlinienförmig einmal durchlaufen, woraufhin dann der Anfang der Warenbahn von der letzten Behandlungskammer, also beispielsweise der achten Behandlungskammer zur ersten Behandlungskammer zurückgeführt wird. Diese bekannte Vorrichtung soll gemäß der dortigen Aufgabenstellung so ausgebildet sein, daß sie sich u.a. auf eine bestimmte Warenfüllung einstellen läßt. Dementsprechend kann jede Kammer Füllstands-Anzeigegeräte für die maximale und minimale Warenfüllung besitzen, so daß die Transporteinrichtungen sowohl bei einer Überfüllung als auch bei einer Unterfüllung zumindest einer Kammer im Sinne der gewünschten Beeinflussung der Warenmenge gesteuert werden kann. Zu diesem Zweck ist dort eine allen Kammern gemeinsame, durchgehende untere Walze vorgesehen, die mit einzelnen, je einer Kammer gesondert zugeordneten oberen Quetschwalzen in der Weise zusammenwirkt, daß in Abhängigkeit von der in der jeweils zugehörigen Behandlungskammer festgestellten Warenfüllung die jeweils zugehörige obere Quetschwalze abgehoben werden kann, wenn der Warenbahntransport aus der Kammer unterbrochen werden soll.From EP-A-0 075 650 (preamble to independent claims 1 and 3) is also a device for Wet treatment of a strand-like textile goods web known. There is a larger one in this treatment device Number of treatment chambers, i.e. in the described Embodiments are eight treatment chambers one after the other or side by side arranged that they are from a web to be treated are traversed approximately helically, which is preferably done continuously, but possibly can also be done discontinuously, with each chamber contain the same or different fleets can. If discontinuous in this known embodiment will be worked one after the other all chambers and the whole device helical go through once, then the beginning the web from the last treatment chamber, for example the eighth treatment chamber first treatment chamber is returned. This well-known Device should according to the task there be designed in such a way that on can set a certain goods filling. Accordingly each chamber can display level indicators for have the maximum and minimum goods filling, so that the transport facilities both in the event of overcrowding as well as underfilling at least one chamber in the sense of influencing the quantity of goods can be controlled. For this purpose there is one continuous, lower roller common to all chambers provided with separate, one chamber each associated upper squeeze rollers cooperates in such a way that depending on the in each associated treatment chamber determined goods filling the respective upper squeeze roller is lifted off can be, if the web transport from the Chamber should be interrupted.

Der Erfindung liegt daher die Aufgabe zugrunde ein Verfahren gemäß dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung nach dem Oberbegriff des Anspruches 3 zu schaffen, durch das bzw. durch die eine strangförmige Warenbahn bei sehr zuverlässigem und relativ einfachem mechanischen Transport in verhältnismäßig kurzer Zeit einer intensiven und schonenden Naßbehandlung unterworfen werden kann.The invention is therefore based on the object of a method according to the preamble of claim 1 and a device according to the preamble of claim 3 to create, through which or through a strand-shaped Goods web with very reliable and relatively simple mechanical transport in a relatively short time Time of an intensive and gentle wet treatment can be subjected.

Diese Aufgabe wird erfindungsgemäß durch die Verfahrensmerkmale im Kennzeichen des Anspruches 1 sowie durch die Vorrichtungsmerkmale im Kennzeichen des Anspruches 3 gelöst.This object is achieved by the method features in the characterizing part of claim 1 as well by the device features in the characterizing part of the claim 3 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of subclaims.

Während bei der zuletzt beschriebenen bekannten Ausführung (EP-A-0 075 650i beispielsweise acht Behandlungskammern schraubenlinienförmig nacheinander von einer zu behandelnden Warenbahn durchlaufen werden (egal ob kontinuierlich oder diskontinuierlich gearbeitet wird), wird nach dem erfindungsgemäßen Verfahren die zu einem endlosen Strang zusammengenähte Warenbahn bei jedem Umlauf durch das in zwei gleiche, parallel nebeneinander liegende Behandlungszonen unterteilte Behandlungsabteil gleichzeitig an zwei Stellen in ein und derselben Behandlungsart behandelt, indem zwei parallel zueinander laufende Abschnitte dieser Warenbahn die beiden Behandlungszonen parallel und gleichzeitig durchlaufen. Demnach kann also die endlos zusammengenähte Warenbahn in ein und demselben Behandlungsabteil an zwei Stellen gleichzeitig mit frischer Flotte, Chemikalien oder auch mit mechanischen Behandlungsmitteln beaufschlagt werden. Vergleicht man diese Verfahrensweise mit den weiter oben geschilderten bekannten Verfahren, dann kann erfindungsgemäß die endlos zusammengenähte Warenbahn gewissermaßen in zwei parallel nebeneinander angeordneten Teil-Kreislaufsystemen naßbehandelt werden, und gegenüber den bekannten Verfahren mit sehr kurzen Umlaufzeiten, die beispielweise mit einer Transportgeschwindigkeit von 400 m/min erreicht werden, genügen bei der erfindungsgemäßen Ausführung Transportgeschwindigkeiten von beispielsweise 200 m/min, da zwei parallellaufende Warenbahnabschnitte die beiden nebeneinander liegenden Behandlungszonen ein und derselben Behandlungsart (in ein und demselben Behandlungsabteil) parallel und gleichzeitig durchlaufen können. Durch das erfindungsgemäße Vorgehen läßt sich somit - im Vergleich zu den bekannten Verfahren - in derselben Umlaufzeit etwa die doppelte Menge an Ware naßbehandeln (färben, bleichen oder dergleichen), oder die gleiche Warenbahnmenge kann etwa in der halben Zeit behandelt werden. Außerdem ist es möglich, bei gleichen Warenmengen und gleichen Behandlungszeiten eine im Vergleich zu den bekannten Ausführungen besonders schonende Behandlung der jeweiligen Warenbahn durchzuführen.While in the known version described last (EP-A-0 075 650i, for example eight treatment chambers helically from one to another be processed through the processing web (regardless of whether continuous or is carried out discontinuously), is according to the inventive method to a endless strand of fabric sewn together with each revolution through that in two of the same, parallel side by side lying treatment zones divided treatment compartment at the same time in two places in one and the same type of treatment treated by two in parallel running sections of this web the two treatment zones run parallel and simultaneously. Accordingly, the endlessly sewn web can in one and the same treatment compartment in two places at the same time with fresh fleet, chemicals or also applied with mechanical treatment agents will. If you compare this procedure with the known methods described above, then according to the invention the endlessly sewn together Goods web in two, so to speak, side by side arranged partial circulatory systems are wet treated, and compared to the known methods with very short turnaround times, for example with a transport speed of 400 m / min are sufficient transport speeds in the embodiment according to the invention of 200 m / min, for example, since two parallel web sections the two next to each other lying treatment zones one and the same Type of treatment (in the same treatment compartment) can run in parallel and simultaneously. By the The procedure according to the invention can thus be compared to the known methods - in the same period wet treat about twice the amount of goods (dye, bleach or the like), or the same Material quantity can be handled in about half the time will. It is also possible for the same amount of goods and same treatment times compared to the known versions particularly gentle treatment the respective web.

Hierbei ist es ferner von Vorteil, wenn die Warenbahn bei mehreren Behandlungsumläufen über Transportwalzen geführt und wenn dabei im Übergang von einer Behandlungszone in die andere wenigstens teilweise Behandlungsflotte aus der Warenbahn abgequetscht wird, wodurch ein besonders rascher Flottenaustausch erreicht werden kann.It is also advantageous if the web with several treatment cycles via transport rollers guided and when doing so in the transition from a treatment zone in the other at least partially treatment fleet is squeezed out of the web, whereby a particularly rapid fleet exchange was achieved can be.

Das Flottenverhältnis bei diesem erfindungsgemäßen Verfahren kann etwa im Bereich von 1 : 2,5 bis 1 : 10 frei gewählt werden.The liquor ratio in this method according to the invention can be free in the range of 1: 2.5 to 1:10 to get voted.

Bei der erfindungsgemäßen Vorrichtung zur diskontinuierlichen Naßbehandlung einer strangförmigen Warenbahn ist in sinnvoller Weise das einzige Behandlungsabteil in zwei derselben Behandlungsart dienende, parallele und gleichzeitig von zwei Abschnitten der endlos zusammengenähten Warenbahn durchlaufene, nebeneinander liegende Behandlungskammern unterteilt, die durch zwei Warenkörbe mit perforierten Wänden gebildet und als Einheit nach Art einer Pendelwaage pendelnd aufgehängt sind. Dabei ist dieser Warenkorbeinheit ein Potentiometer in der Weise zugeordnet, daß bei ungleicher Warenbelastung der beiden Warenkörbe eine Pendelbewegung der Warenkorbeinheit durch das Potentiometer abtastbar und eine Belastungs-Ausgleichssteuerung für die beiden Warenkörbe aktivierbar ist. Auf diese Weise kann ein äußerst sicherer und zuverlässiger Warenbahnumlauf durch eine gleichmäßige Verteilung der beiden Warenkörbe einer Einheit und damit auch eine äußerst gleichmäßige Naßbehandlung gewährleistet werden.In the device for discontinuous Wet treatment of a strand-like web is the only treatment compartment in a sensible way serving in two of the same type of treatment, parallel and simultaneously from two sections of the endlessly sewn together Goods run through, lying side by side Treatment chambers divided by two shopping carts formed with perforated walls and as a unit suspended in the manner of a pendulum scale are. This basket unit is a potentiometer assigned in such a way that in the case of unequal loading of the two shopping baskets a pendulum movement of the Cart unit can be scanned by the potentiometer and a load compensation control for the two shopping baskets can be activated. This way one can be extremely safe and reliable web circulation through an even distribution of the two shopping carts one Unity and therefore an extremely even one Wet treatment can be guaranteed.

Von besonderem Vorteil ist es dabei ferner, wenn die beiden Behandlungskammern in der Weise im zugehörigen Behandlungsabteil angeordnet sind, daß jeweils das Einlaufende der einen Behandlungskammer unmittelbar neben dem Auslaufende der anderen Behandlungskammer liegt und die Verbindung zwischen jedem Auslaufende und dem benachbarten Einlaufende durch eine Transportwalze gebildet ist.It is also of particular advantage if the two treatment chambers in the manner in which Treatment compartment are arranged that the inlet end one treatment chamber right next to it the outlet end of the other treatment chamber and the connection between each outlet end and the neighboring one Inlet end formed by a transport roller is.

Der allgemeine Aufbau der erfindungsgemäßen Vorrichtung (Diskontinue-Naßbehandlungsvorrichtung) sei zunächst anhand der Perspektivansicht in Fig.1 erläutert, in der nur ein Behandlungsabteil 1 veranschaulicht ist, das zur Naßbehandlung (insbesondere färben, bleichen, waschen oder dgl.) einer endlos zusammengenähten strangförmigen Warenbahn 2 dient, die in Richtung der Pfeile 3 in wenigstens einem einmaligen Umlauf durch das Behandlungsabteil 1 mechanisch transportiert wird.The general structure of the device according to the invention (Discontinuous wet treatment device) first explained with the perspective view in Fig.1, in the only one treatment compartment 1 is illustrated, which for wet treatment (especially dyeing, bleaching, wash or the like) one endless sewn together strand-shaped web 2 is used in the direction of arrows 3 in at least one time Circulation through the treatment compartment 1 mechanically is transported.

Das Behandlungsabteil 1 ist in zwei parallel und gleichzeitig von zwei Warenbahnabschnitten 2a, 2b durchlaufene, nebeneinanderliegende Behandlungskammern 4, 5 für ein und dieselbe Behandlungsart unterteilt. Für den mechanischen Transport der Warenbahn 2 sorgen vorzugsweise als Transportwalzen 6, 7 ausgebildete Transportorgane, die in der Verbindung zwischen den beiden Behandlungskammern 4, 5 angeordnet sind.The treatment compartment 1 is parallel and in two simultaneously from two web sections 2a, 2b continuous, adjacent treatment chambers 4, 5 divided for one and the same type of treatment. For the mechanical transport of the web 2 provide preferably designed as transport rollers 6, 7 Transport organs in the connection between the two treatment chambers 4, 5 are arranged.

Wie in Fig.1 zu erkennen ist, besitzt jede Behandlungskammer 4, 5 ein Einlaufende 4a bzw. 5a sowie ein entgegengesetztes Auslaufende 4b bzw. 5b, und diese beiden Behandlungskammern 4, 5 sind dabei im zugehörigen Behandlungsabteil 1 derart zusammengeordnet, daß jeweils das Einlaufende der einen Behandlungskammer unmittelbar neben dem Auslaufende der anderen Behandlungskammer liegt, d.h. das Einlaufende 4a der Behandlungskammer 4 liegt unmittelbar neben dem Auslaufende 5b der Behandlungskammer 5, während das Auslaufende 4b der ersten Kammer 4 unmittelbar neben dem Einlaufende 5a der zweiten Kammer 5 liegt. Die Verbindung zwischen jedem Auslaufende 4b bzw. 5b und dem benachbarten Einlaufende 4a bzw. 5a wird dann durch die jeweils zugehörige Transportwalze 6 bzw. 7 gebildet, die mit ihrer Drehachse 6a bzw. 7a vorzugsweise parallel zu und mit entsprechendem Abstand über den unmittelbar aneinander liegenden Trennwänden 8 bzw. 9 zwischen den beiden Behandlungskammern 4, 5 liegen.As can be seen in Fig. 1, each treatment chamber has 4, 5 an inlet end 4a and 5a and an opposite end Outgoing ends 4b and 5b, and these two Treatment chambers 4, 5 are in the associated treatment compartment 1 arranged so that each the inlet end of a treatment chamber immediately next to the outlet end of the other treatment chamber lies, i.e. the inlet end 4a of the treatment chamber 4 lies immediately next to the outlet end 5b of the treatment chamber 5, while the outlet end 4b of the first Chamber 4 immediately next to the inlet end 5a of the second Chamber 5 is located. The connection between each end of the run 4b or 5b and the adjacent inlet end 4a or 5a is then through the associated transport roller 6 and 7 formed, with their axis of rotation 6a or 7a preferably parallel to and with the corresponding Distance over the immediately adjacent Partitions 8 and 9 between the two treatment chambers 4, 5 lie.

Die beiden Behandlungskammern jedes Behandlungsabteiles 1 sind vorzugsweise durch zwei Warenkörbe 4, 5 mit perforierten Wänden (vgl. bei 10 angedeutete Perforation in Fig.1) gebildet. Diese beiden Warenkörbe 4, 5 sind vorzugsweise als Einheit (Paar) nach Art einer Pendelwaage pendelnd aufgehängt, was in Fig.1 durch eine Art Waagebalken 11 und eine Pendelachse 12 angedeutet ist, um die die Warenkorbeinheit 4, 5 bei ungleicher Warenbelastung in Richtung des Doppelpfeiles 13 drehen bzw. pendeln kann.The two treatment chambers of each treatment compartment 1 are preferably with two baskets 4, 5 with perforated walls (see at 10 indicated perforation in Fig.1) formed. These two shopping carts 4, 5 are preferably as a unit (pair) like a Pendulum scale suspended, what in Fig.1 by a kind of balance beam 11 and a pendulum axis 12 indicated is by which the shopping cart unit 4, 5 at unequal Goods load in the direction of the double arrow 13 can rotate or commute.

Dieser Warenkorbeinheit 4, 5 ist ein Potentiomet-er 14 in der Weise zugeordnet, daß bei ungleicher Warenbelastung der beiden Warenkörbe 4, 5 eine Dreh- bzw. Pendelbewegung der Warenkorbeinheit in Richtung des schwereren bzw. stärker gefüllten Warenkorbes auftritt. Diese Pendelbewegung in der einen oder anderen Richtung des Doppelpfeiles 13 ist durch das Potentiometer 14 abtastbar, wodurch ein entsprechendes Meßsignal an eine nur vereinfacht angedeutete Steuereinrichtung 15 weitergeleitet wird, von der aus ein entsprechendes Steuersignal an eine der beiden Transportwalzen 6 oder 7 in dem Sinne weitergeleitet wird, daß eine Belastungsausgleichssteuerung für die beiden Warenkörbe 4, 5 aktivierbar ist. Letzteres kann auf einfache Weise durch eine entsprechende Änderung der Drehgeschwindigkeit zumindest einer der beiden Transportwalzen 6 oder 7 erreicht werden. Zu diesem Zweck sind die beiden Transportwalzen 6, 7 mit gesonderten Antrieben mit je einem gesonderten Antriebsmotor 16 bzw. 17 (Fig.2) versehen, so daß sie mit gesondert regelbarer Drehgeschwindigkeit in Richtung der Pfeile 6b bzw. 7b angetrieben werden können. Mit diesen Antriebsmotoren steht das Potentiometer 14 über die Steuereinrichtung 15 in Steuerverbindung.This shopping cart unit 4, 5 is a potentiometer 14 assigned in such a way that in the case of unequal loading of the two shopping carts 4, 5 a rotating or pendulum movement the cart unit towards the heavier one or more filled shopping cart occurs. This pendulum movement in one direction or another the double arrow 13 can be scanned by the potentiometer 14, whereby a corresponding measurement signal to a forwarded control device 15 indicated only in a simplified manner from which a corresponding control signal to one of the two transport rollers 6 or 7 in the sense is passed that a load balancing control can be activated for the two shopping baskets 4, 5 is. The latter can be done easily a corresponding change in the rotational speed at least one of the two transport rollers 6 or 7 is reached will. For this purpose, the two transport rollers 6, 7 with separate drives with one each separate drive motor 16 or 17 (Fig.2) provided, so that they can be rotated at a separately adjustable speed are driven in the direction of arrows 6b and 7b can. The potentiometer is located with these drive motors 14 via the control device 15 in control connection.

Aus den Fig.1 und 2 läßt sich ferner entnehmen, daß jeder Transportwalze 6, 7 eine Ausdrückwalze 18 bzw. 19 zugeordnet ist. Jede Ausdrückwalze 18, 19 ist - wie in Fig.2 bei der linken Ausdrückwalze 18 zu erkennen ist - in Schwenkarmen 20 frei drehbar gelagert, und zwar in der Weise, daß jede Ausdrückwalze 18 bzw. 19 wahlweise bzw. im Bedarfsfalle gegen die zugehörige Transportwalze 6 bzw. 7 gedrückt werden kann, wodurch zwischen den beiden hierbei zusammenwirkenden Walzenpaaren 6 und 18 bzw. 7 und 19 ein Quetschspalt ausgebildet wird, durch den die zu behandelnde Warenbahn 2 hindurchtransportiert werden kann, damit im Bedarfsfalle wenigstens ein Teil der mitgeführten Behandlungsflotte aus der Warenbahn 2 abgequetscht werden kann, wobei diese abgequetschte Flotte dann in das darunter liegende Auslaufende 4b bzw. 5b des zugehörigen Warenkorbes 4 bzw. 5 zurückfließen kann.From Figures 1 and 2 it can also be seen that everyone Transport roller 6, 7 a squeezing roller 18 and 19 respectively assigned. Each squeeze roller 18, 19 is - as in 2 can be seen in the left ejection roller 18 - in swivel arms 20 freely rotatable, namely in the way that each squeeze roller 18 or 19 optionally or, if necessary, against the associated transport roller 6 or 7 can be pressed, whereby between the two roller pairs 6 and 18 or 7 and 19 a pinch gap is formed, through which the web 2 to be treated is transported can be, so at least if necessary a part of the treatment fleet carried along from the web 2 can be squeezed, this squeezed Fleet then in the spout below 4b or 5b of the associated shopping cart 4 or 5 can flow back.

Was die Ausbildung der Warenkörbe 4, 5 anbelangt, so können diese in jeder geeigneten Form hergestellt sein, die für die erfindungsgemäße Behandlungsweise geeignet ist. Besonders bevorzugt wird jedoch eine Ausbildung der Warenkörbe 4, 5 jeweils nach Art von gleichgroßen, U-förmigen Kanälen, wie es in den Fig. 1 und 2 veranschaulicht ist.Regarding the design of shopping baskets 4, 5, see above can be made in any suitable form, suitable for the treatment according to the invention is. However, training is particularly preferred the shopping baskets 4, 5 each of the same size, U-shaped channels, as illustrated in FIGS. 1 and 2 is.

Darüber hinaus wird es vorgezogen, die Warenkorbeinheit mit den Körben 4, 5 in einem die Behandlungsflotte 21 enthaltenden gemeinsamen Behandlungsbehälter 22 anzuordnen. Durch eine zweckmäßige Art der weiter oben bereits erwähnten Perforierung der Warenkorbwände dringt zum einen genügend Behandlungsflotte 21 in jeden in die Behandlungsflotte eingetauchten Warenkorb 4, 5 ein, zum andern wird durch diese Perforation 10 der Warenkorbwände gleichzeitig eine äußerst gute Durchmischung der Behandlungsflotte während des Behandlungsvorganges gewahrleistet.In addition, the shopping cart unit is preferred with the baskets 4, 5 in a treatment liquor 21 containing common treatment container 22 to be arranged. By an expedient kind of already above perforation of the cart walls mentioned penetrates on the one hand enough treatment fleet 21 in each in the Treatment liquor immersed in basket 4, 5 to is changed by this perforation 10 of the shopping cart walls at the same time an extremely good mixing of the Treatment fleet guaranteed during the treatment process.

Anhand der Fig.1 und 2 ist ferner veranschaulicht, daß im Bereich des oberen Einlaufendes 4a, bzw. 5a jeder Behandlungskammer bzw. jedes Warenkorbes 4 bzw. 5 sowie unterhalb der zugehörigen Transportwalze 6 bzw. 7 ein von der strangförmigen Warenbahn 2 durchlaufener, düsenförmiger Overflow-Trichter 23 angeordnet ist. Unterhalb jedes Overflow-Trichters 23 ist ferner vorzugsweise noch ein den Warenbahnstrang aufnehmendes und weiterleitendes Prallblech 24 angeordnet. Jeder Overflow-Trichter ist dabei für ein gerichtetes Einführen des Warenbahnstranges in die zugehörige Behandlungskammer bzw. den sie bildenden Warenkorb 4 bzw. 5 ausgebildet, wobei jeder Overflow-Trichter 23 an eine Flottenleitung 25 angeschlossen ist.1 and 2 also illustrate that in the area of the upper inlet end 4a or 5a each Treatment chamber or each basket 4 or 5 as well below the associated transport roller 6 or 7 of the strand-shaped web 2, nozzle-shaped Overflow funnel 23 is arranged. Below each overflow funnel 23 is also preferred another one that takes up the web and forwarding baffle 24 arranged. Any overflow funnel is for directional insertion of the web in the associated treatment chamber or the shopping cart 4 or 5 forming them, each overflow funnel 23 to a fleet line 25 is connected.

Die Ausbildung und Anordnung jedes Overflow-Trichters 23 sowie dessen Zusammenordnung mit dem zugehörigen Prallblech 24 sorgen in optimaler Weise dafür, daß der von der zugehörigen Transportwalze 6 bzw. 7 kommende Abschnitt der strangförmigen Warenbahn 2 sauber und vorzugsweise mit einwandfreier Faltenverlegung in das Einlaufende des zugehörigen Warenkorbes 4 bzw. 5 eingeführt wird. Dabei ist es ausreichend, den Overflow-Trichter 23 und das nachgeschaltete Prallblech 24 in geeigneter Weise fest anzuordnen bzw. zueinander zusammenzuordnen. Es kann jedoch auch von Vorteil sein, wenn der Overflow-Trichter 23 und das Prallblech 24 in geeigneter Weise einstellbar gehaltert sind, so daß im Bedarfsfalle eine nachträgliche Neueinstellung dieser Teile möglich ist.The design and arrangement of each overflow funnel 23 and its arrangement with the associated Baffle plate 24 optimally ensure that the one coming from the associated transport roller 6 or 7 Section of the strand-like web 2 clean and preferably with perfect pleating in the incoming end of the associated shopping basket 4 or 5 is introduced. It is sufficient to use the overflow funnel 23 and the downstream baffle plate 24 to be firmly arranged in a suitable manner or to be arranged together. However, it can also be an advantage if the overflow funnel 23 and the baffle 24 in are suitably supported adjustable, so that in If necessary, a subsequent readjustment of this Parts is possible.

Anhand der vereinfachten Schemadarstellung in Fig.3 läßt sich außerdem erkennen, daß die erfindungsgemäße Diskontinue-Naßbehandlungsvorrichtung, wie sie bisher anhand einer einzigen Warenkorbeinheit mit den Warenkörben 4 und 5 (Fig.1 und 2) erläutert worden ist, auch mit mehreren Warenkorbeinheiten 1a, 1b, 1c in ein und demselben Behandlungsbehälter 22' ausgestattet sein kann, wobei dann diese Warenkorbeinheiten 1a, 1b, 1c baukastenartig nebeneinander in dem gemeinsamen Behandlungsbehälter 22' angeordnet und für den gleichen Behandlungsvorgang mehrerer parallel laufender, jeweils endlos umlaufender Warenbahnen in demselben Flottenbad 21' betreibbar sind. Dies kommt hauptsächlich für größere Anlagen bzw. Vorrichtungen in Frage, wobei dann jede Warenkorbeinheit 1a, 1b, 1c mit einem optimalen Wareninhalt (Warenfüllungsgrad) arbeiten kann. Auch hier besteht jede Warenkorbeinheit wiederum aus zwei Warenkörben 4, 5 mit perforierten Wänden, wie es weiter oben anhand der Fig.1 und 2 im einzelnen erläutert worden ist. Using the simplified schematic representation in Fig. 3 can also be seen that the invention Discontinuous wet treatment device, as previously used a single shopping cart unit with the shopping carts 4 and 5 (Fig.1 and 2) has been explained, too with several shopping cart units 1a, 1b, 1c in one and the same treatment tank 22 ' can, these shopping cart units 1a, 1b, 1c modularly next to each other in the common treatment tank 22 'arranged and for the same treatment process several running in parallel, each endless revolving webs in the same fleet bath 21 'are operable. This comes mainly for larger systems or devices in question, where then each shopping cart unit 1a, 1b, 1c with an optimal one Goods content (degree of filling) can work. Also here each shopping cart unit consists of two Shopping carts 4, 5 with perforated walls as it continues 1 and 2 have been explained in detail above is.

Egal ob die Vorrichtung mit nur einer einzigen Warenkorbeinheit 4, 5 oder mehreren gleichartig aufgebauten und baukastenartig nebeneinanderliegenden Warenkorbeinheiten ausgeführt ist, arbeitet jede dieser Warenkorbeinheiten nach der weiter oben beschriebenen gleichen Verfahrensweise, wonach also bei jedem Warenbahnumlauf zwei parallel zueinander laufende Warenbahnabschnitte 2a, 2b in zwei gleichen, nebeneinanderliegenden und derselben Behandlungsart dienenden Behandlungszonen (Behandlungskammern bzw. Warenkörbe 4, 5) des Behandlungsabteiles 1 gleichzeitig behandelt werden, und zwar in endlos zusammengenähter Strangform bei einer beliebigen Anzahl von Umläufen. Bei diesen Umläufen könnte es dann beispielsweise durch einen Schlupf auf den Tansportwalzen 6, 7 vorkommen, daß unterschiedliche Warenbahn-Füllmengen in den beiden Warenkörben 4, 5 einer Einheit enthalten sind. Dies kann auf einfache Weise durch die pendelnde Aufhängung jeder Warenkorbeinheit und die zugehörige Steuerung über das Potentiometer 14 ausgeglichen werden, wobei jede Warenkorbeinheit nach Art einer Pendelwaage gehaltert bzw. aufgehängt ist. Wenn sich dabei beispielsweise im linken Warenkorb einer Einheit weniger Ware befindet als im rechten, dann kippt diese Warenkorbeinheit in Richtung des rechten Warenkorbes. Diese Dreh- bzw. Pendelbewegung um die Pendelachse 12 wird mit Hilfe des Potentiometers 14 abgetastet, so daß über die Steuereinrichtung 15 der Antrieb für die Auszugsgeschwindigkeit des rechten Warenkorbes nach oben und gegebenenfalls gleichzeitig die Auszugsgeschwindigkeit für die andere Transportwalze am linken Warenkorb nach unten korrigiert wird. No matter whether the device with just a single shopping cart unit 4, 5 or more similarly constructed and modular shopping cart units next to each other is executed, each of these shopping cart units works after the one described above the same procedure, according to which every circulation of goods two parallel web sections 2a, 2b in two identical, side by side and treatment zones serving the same type of treatment (Treatment chambers or shopping baskets 4, 5) of the treatment compartment 1 treated at the same time in endlessly sewn together Strand shape for any number of rounds. It could then, for example, with these cycles occur due to slippage on the transport rollers 6, 7, that different web fill quantities in the two shopping carts 4, 5 of a unit are included. This can be done easily by the swinging suspension each shopping cart unit and the associated one Control can be compensated via the potentiometer 14, each shopping cart unit in the manner of a Pendulum scale is supported or suspended. If for example in the left shopping cart of a unit If there is less goods than in the right one, it tilts Shopping cart unit in the direction of the right shopping cart. This rotary or pendulum movement about the pendulum axis 12 is scanned using the potentiometer 14 so that via the control device 15, the drive for the Pull-out speed of the right shopping cart above and if necessary at the same time Pull-out speed for the other transport roller on left cart is corrected down.

Ein Zahlenbeispiel soll nachfolgend das erfindungsgemäße Verfahren - beispielsweise anhand Fig.1 - nochmals verdeutlichen:A numerical example is the following the inventive Procedure - for example based on Fig.1 - again clarify:

Es sei angenommen, daß sich in einer Warenkorbeinheit Ware (eine Warenbahn) in einer Menge von 150 kg befindet; das Laufmetergewicht beträgt 200 g/m, womit 5 laufende Meter Warenbahn 1 kg wiegen, so daß die 150 kg Ware eine Warenbahnlänge von 750 m bedeuten.It is assumed that there is one shopping cart unit Goods (a web) located in an amount of 150 kg; The running meter weight is 200 g / m, which means 5 running meters of web weigh 1 kg, so that the 150 kg of goods mean a web length of 750 m.

Die angestrebte Umlaufzeit soll maximal 4 Minuten betragen. Würde man die zuvor definierte Warenbahn nach einem der eingangs geschilderten bekannten Verfahren naßbehandeln, so müßte die Transportgeschwindigkeit für den Warenbahnumlauf mindestens 187,5 m/min betragen, damit die gesamte Warenbahnlänge einmal das Flottenbad durchläuft.The target orbital period should be a maximum of 4 minutes. Would you follow the previously defined web one of the known methods described above wet treatment, the transport speed for the web circulation is at least 187.5 m / min, so that the entire length of the web is once the fleet bath goes through.

Da bei dem erfindungsgemäßen Verfahren in der geschilderten Weise jeweils zwei parallel zueinander laufende Warenbahnabschnitte in zwei gleichen, nebeneinanderliegenden Behandlungszonen (Warenkörben 4, 5) desselben Behandlungsabteiles 1 gleichzeitig behandelt werden, braucht die Warenbahn nur mit einer Transportgeschwindigkeit von maximal 93,75 m/min transportiert zu werden, damit die gesamte Warenbahnlänge in den genannten 4 Minuten einmal vollkommen das Flottenbad durchsetzen kann. Wird demgegenüber auch bei dem erfindungsgemäßen Verfahren mit derselben Umlaufgeschwindigkeit wie bei den erwähnten bekannten Verfahren gearbeitet, also mit 187,5 m/min, dann sinkt die Umlaufzeit für einen Umlauf der ganzen Warenbahn (bei erfindungsgemäßer Behandlung) auf 2 Minuten, so daß der Naßbehandlungsvorgang dann in etwa der Hälfte der Zeit stattfinden kann, verglichen mit den bekannten Verfahren.Since in the method according to the invention in the Way two each running parallel to each other Web sections in two identical, side by side Treatment zones (baskets 4, 5) of the same Treatment compartment 1 are treated simultaneously, the web only needs one transport speed to be transported at a maximum of 93.75 m / min, thus the entire length of the web in the mentioned Push the bath completely through for 4 minutes can. In contrast, is also the inventive Travel at the same speed as at worked with the known methods mentioned, that is with 187.5 m / min, then the round trip time for one round decreases the entire web (with treatment according to the invention) to 2 minutes, so that the wet treatment process then in compared to about half the time with the known methods.

Vergleicht man hierzu noch die Möglichkeit, mehrere solcher Warenkorbeinheiten in einem einzigen gemeinsamen Behandlungsbehälter baukastenartig zusammenzuordnen, dann vervielfacht sich die Naßbehandlungsleistung der so erweiterten Vorrichtung um die Anzahl der verwendeten Warenkorbeinheiten.If you compare the possibility of several such shopping cart units in a single common To arrange treatment containers in a modular manner, then the wet treatment performance multiplies the device so expanded by the number of used Shopping cart units.
