Description

Die Erfindung betrifft eine Vorrichtung zum Waschen langer Bahnen, insbesondere textiler Bahnen.The invention relates to a device for washing long webs, in particular textile webs.

Textile Bahnen müssen nach dem Färben und/oder Ausrüsten gewaschen werden. Dazu werden die Bahnen in an sich bekannten Trommelwaschmaschinen mit einer Siebtrommel eingebracht und dort gewaschen. Derartige Trommelwaschmaschinen sind verhältnismäßig teuer, das Einbringen und Ausbringen der zu waschendenden Bahn in die Trommelwaschmaschine sowie der Waschvorgang benötigt verhältnismäßig viel Zeit und die gewaschene Bahn muß anschließend wieder geglättet sowie ggf. zu einem Wickel oder Ballen gerollt werden. Das alles ist aufwendig.Textile webs must be washed after dyeing and / or finishing. For this purpose, the webs are introduced and washed there in drum washing machines known per se with a sieve drum. Such drum washing machines are relatively expensive, the introduction and removal of the web to be washed in the drum washing machine and the washing process takes a relatively long time and the washed web must then be smoothed again and possibly rolled into a wrap or bale. All of this is expensive.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Waschen langer Bahnen, insbesondere textiler Bahnen anzugeben, die weniger Aufwand für die Handhabung der Bahnen erfordert und in der die Bahnen in kürzerer Zeit gewaschen werden.The object of the invention is to provide a device for washing long webs, in particular textile webs, which requires less effort for the handling of the webs and in which the webs are washed in a shorter time.

Diese Aufgabe wird gelöst mit einer Vorrichtung zum Waschen langer Bahnen, insbesondere textiler Bahnen, die gekennzeichnet ist durch ein sich im wesentlichen vertikal erstreckendes, für den Durchlauf der Bahn eingerichtetes Gehäuse mit einem Wasserzulauf im Bereich des oberen Endes, welches Sammelflächen für das ablaufende Waschwasser und an den Rändern der Sammelflächen Führungskanten für die zu waschende Bahn aufweist.This object is achieved with a device for Washing long webs, in particular textile webs, which is characterized by a substantially vertically extending housing which is set up for the passage of the web and has a water inlet in the region of the upper end, which has collecting surfaces for the washing water running off and leading edges for the edges of the collecting surfaces has to be washed web.

Bei dieser Vorrichtung wird die zu waschende Bahn nicht in eine Trommel oder Kammer eingebracht und dort pulsierend hin- und herbewegt, sondern an den Führungskanten der Sammelflächen vorbeigeführt, wobei die Bahn und das Waschwasser gleichsam im Gegenstrom geführt werden, so daß die Vorwäsche mit bereits weitgehend verschmutztem Waschwasser beginnt und die darüber angeordneten Wasch- stufen an den Führungskanten der Sammelflächen jeweils weniger verschmutztes Wasser erhalten, während die letzte Waschstufe frisches Waschwasser erhält. Die Waschwirkung beruht im wesentlichen darauf, daß das ablaufende Waschwasser im Bereich der Führungskanten Wirbel bildet, die in erheblichem Maße zur Waschwirkung beitragen, woraus auch eine erhebliche Verkürzung der Waschzeit resultiert. Die Führungskanten streifen gleichzeitig überschüssiges Wasser ab bzw. sie verhindern, daß die Bahn überschüssiges Wasser mit transportiert. Deswegen ist die Restfeuchte der Bahn nach dem Verlassen der Vorrichtung vergleichsweise gering.In this device, the web to be washed is not introduced into a drum or chamber and pulsed back and forth there, but is guided past the leading edges of the collecting surfaces, the web and the wash water being guided in countercurrent as it were, so that the prewashing is already largely complete soiled wash water begins and the overlying wash - stages each receive less polluted water on the guide edges of the collection surfaces, while the last washing stage receives fresh wash water. The washing effect is essentially based on the fact that the washing water running off forms vortices in the area of the leading edges, which contribute to the washing effect to a considerable extent, which also results in a considerable reduction in the washing time. The leading edges simultaneously wipe off excess water or prevent the web from carrying excess water with it. Therefore, the residual moisture of the web is comparatively low after leaving the device.

Die zu waschende Bahn kann, sofern sie auf einem Wickel oder Ballen aufgerollt ist, von diesem Wickel oder Ballen abgezogen, durch die Vorrichtung geführt und anschließend, ggf. nach einem Trocknungsvorgang wieder aufgerollt werden.The web to be washed, if it is rolled up on a wrap or bale, can be pulled off this wrap or bale, passed through the device and then, if necessary after a drying process, rolled up again.

Zweckmäßig werden die Führungskanten der Sammelflächen so angeordnet, daß sie einen zickzackförmigen Weg für die Bahn definieren. Die über einer Eintrittsöffnung des Gehäuses in die Vorrichtung eingeführte und über eine Austrittsöffnung des Gehäuses aus der Vorrichtung herausgezogene Bahn wird dann innerhalb des Gehäuse auf einem mehr oder weniger zickzackförmigen Weg geführt, wobei sie sich wechselweise an die Führungskanten anlegt und zwischen benachbarten Führungskanten vergleichsweise glatt gespannt ist, so daß"jede Führungskante wegen der sich daran ausbildenden Wirbel nicht nur einen Vorwäscher sondern gleichzeitig auch einen Abstreifer bildet. Es versteht sich, daß die Führungskanten so ausgebildet und abgerundet sind, daß eine mechanische Beanspruchung der Bahn weitgehend vermieden wird.The leading edges of the collecting surfaces are expediently arranged such that they define a zigzag path for the web. The web that is introduced into the device via an inlet opening of the housing and pulled out of the device via an outlet opening of the housing is then guided within the housing in a more or less zigzag-shaped way, alternately resting against the guide edges and tensioned comparatively smoothly between adjacent guide edges is so that "each leading edge not only forms a pre-washer but also a scraper at the same time because of the vortices formed on it. It goes without saying that the leading edges are designed and rounded in such a way that mechanical stress on the web is largely avoided.

Der Wasserzulauf ist grundsätzlich beliebig. Es kann genügen, Waschwasser einfach von oben in das Gehäuse einlaufen zu lassen. Nach bevorzugter Ausführungsform der Erfindung können aber als Wasserzulauf wenigstens zwei aufunterschiedlichen Seiten eines Führungsweges der zu waschenden Bahn und in Bewegungsrichtung der Bahn mit gegenseitigem Abstand angebrachte Waschdüsenanordnungen vorgesehen sein. Die Waschdüsen dieser Waschdüsenanordnungen können jeweils auf den Führungsweg gerichtet sein. Dabei sollte jede Waschdüsenanordnung wenigstens die Breite des Führungsweges und eine Breitschlitzdüse oder eine Reihe von einzelnen Waschdüsen aufweisen. Vorteilhaft ist eine Ausführungsform, bei der jede Waschdüsenanordnung aus einem rohrförmigen oder kastenförmigen Körper besteht, der auf seiner dem Führungsweg, d.h. der Bahn zugewandten Seiten als Waschdüsen dienende Öffnungen aufweist. Besonders günstig werden die Verhältnisse dann, wenn die dem Führungsweg zugewandte Seite jeder Waschdüsenanordnung von Wandungen gebildet ist, die unter einem Winkel zu einander angeordnet sind und eine Ausnehmung auf dieser Seite definieren, wobei die Wandungen an sich quer zur Bewegungsrichtung der Bahn erstreckenden Kanten enden und dort an weiterführende Wandungen angeschlossen sind. Dann können nämlich die Kanten ihrerseits als Führungskanten für die zu waschende Bahn ausgebildet sein. Da das aus den Düsen gegen die Bahn gespritzte Wasser sich innerhalb der so gebildeten Ausnehmung verteilt, bilden sich insbesondere in den Eckbereichen,d.h.im Bereich der Kanten starke Wirbel aus, die in erheblichem Maße zur Waschwirkung beitragen und die ähnlich wirken, wie die Führungskanten der Sammelflächen.The water inlet is basically arbitrary. It can be sufficient to simply let wash water run into the housing from above. According to a preferred embodiment of the invention, however, at least two washing nozzle arrangements arranged on different sides of a guide path of the web to be washed and in the direction of movement of the web with mutual spacing can be provided as the water inlet. The washing nozzles of these washing nozzle arrangements can each be directed towards the guide path. Each wash nozzle arrangement should have at least the width of the guide path and a slot die or a row of individual wash nozzles. An embodiment is advantageous in which each washing nozzle arrangement consists of a tubular or box-shaped body which has openings serving as washing nozzles on its sides facing the guide path, ie the web. The conditions are particularly favorable when the route facing side of each washing nozzle arrangement is formed by walls which are arranged at an angle to one another and define a recess on this side, the walls ending at edges which extend transversely to the direction of movement of the web and are connected there to further walls. Then the edges can in turn be designed as leading edges for the web to be washed. Since the water sprayed from the nozzles against the web is distributed within the recess formed in this way, strong vortices form in particular in the corner regions, that is to say in the region of the edges, which contribute significantly to the washing effect and which have a similar effect to the leading edges of the collecting surfaces .

Bei einer bevorzugten Ausführungsform der Erfindung sind die Waschdüsenanordnungen vertikal übereinander angeordnet. Sie sind von einem Gehäuse umgeben, welches die Sammelflächen für das ablaufende Wasser aufweist. Die Sammelflächen sind zur Horizontalen vorzugsweise unter einem Winkel von 45 Grad geneigt und führen das ablaufende Wasser in den Bereich der Führungskanten, wo sich die eingangs erwähnten starken Wirbel bilden.In a preferred embodiment of the invention, the washing nozzle arrangements are arranged vertically one above the other. They are surrounded by a housing, which has the collecting areas for the running water. The collecting surfaces are preferably inclined at an angle of 45 degrees to the horizontal and guide the running water into the area of the leading edges, where the strong vortices mentioned at the beginning form.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigt die einzige Figur in schematischer Darstellung eine Vorrichtung zum Waschen langer textiler Bahnen. bzw. vorbehandeltIn the following an embodiment of the invention shown in the drawing is explained; it shows the only figure in a schematic representation of a device for washing long textile webs. or pretreated

Eine textile Bahn 1, die gefärbt und ausgerüstet/worden ist, wird über eine Umlenkrolle 2 und eine untere Eintrittsöffnung 3 in die Vorrichtung eingeführt, auf einem im wesentlichen vertikalen Weg durch die Vorrichtung geführt, dort gewaschen und anschließend durch eine obere Austrittsöffnung 4 und eine Umlenkrolle 5 aus der Wirbelbildung im Bereich der Führungskanten. wasser von den Sammelflächen 17 abläuft, reinigt es die an den Führungskanten18 vorbeigeführte Bahn 1.A textile web 1, which has been dyed and finished / is introduced into the device via a deflection roller 2 and a lower inlet opening 3, is guided through the device in a substantially vertical path, washed there and then through an upper outlet opening 4 and one Deflection roller 5 from the Vortex formation in the area of the leading edges. water drains from the collecting surfaces 17, it cleans the web 1 guided past the leading edges 18.

Die durch die Einführungsöffnung 3 zugeführte Bahn 1 wird mit weitgehend verbrauchtem Waschwasser beaufschlagt, das über die unterste Sammelfläche 17 abläuft und im Bereich der zugeordneten Führungskanten einen starken Wirbel bildet, der an der Bahn 1 haftende Schmutzteile zumindest löst, und teilweise aber auch mitnimmt. Wenn die zwischen den Führungskanten 18 im wesentlichen glattgespannte Bahn in den Bereich der nächsten Führungskante gelangt, wird sie bereits mit weniger verschmutztem Waschwasser gewaschen. Das setzt sich auf dem vertikalen Weg der Bahn 1 durch die Vorrichtung weiter fort, wobei jeweils im Bereich der Führungskanten 18 starke Wirbel entstehen, die die Wäsche wirksam unterstützen. Schließlich gelangt die Bahn 1 in den Bereich der Waschdüsenanordnungen 6,7 und wird dort mit reinem Waschwasser beaufschlagt. Die Waschwirkung beruht einerseits auf der Wirkung der aus den Düsen 12 austretenden Strahlen und andererseits auf der Wirbelbildung im Bereich der Führungskanten 13, 14 dieser Waschdüsenanordnungen. Danach ist die Bahn weitgehend gereinigt, so daß sie an Abstreifern 23, 24, die die obere Austrittsöffnung 4 begrenzen, aus der Vorrichtung herausgeführt werden kann. Es hat sich gezeigt, daß bei einer Gesamthöhe von ca. 0,6 Meter der Vorrichtung hohe Bahngeschwindigkeiten möglich sind, ohne daß die Waschwirkung beeinträchtigt wird. Es hat sich herausgestellt, daß die Waschwirkung mit wachsender Bahngeschwindigkeit verbessert wird. Das beruht möglicherweise auf dem Einfluß der Bahn auf die stellung der Figur zwei Gehäusewandungen 15,16 aufweist, die im wesentlichen spiegelbildlich ausgeführt sind. Im oberen, die Waschdüsenanordnungen 6,7 umschließenden Gehäuseabschnitte besitzen die Wandungen etwa trapezförmigen Querschnitt. Die unteren Trapezflächen definieren Sammelflächen 17, die an Führungskanten 18 im Bereich des Weges der Bahn 1 enden. An die Führungskanten 18 schließen jeweils im wesentlichen horizontale Wandungsabschnitte 19 an, von denen wiederum zur Horizontalen, vorzugsweise unter einem Winkel von 45 Grad geneigte Sammelflächen 17 mit anschließenden Führungskanten 18 ausgehen. Im Ergebnis entsteht die in der Figur dargestellte sägezahnförmigeAusbildung, bei der die Sammelflächen 17 und die Führungskanten 18 der beiden Gehäusewandungen 15,16 in vertikaler Richtung zueinander versetzt sind. Die Anordnung im einzelnen ist so, daß die Führungskanten 18 der Sammelflächen 17 ebenso wie die Kanten 13,14 der Waschdüsenanordnungen 6, 7 einen zickzackförmigen-Weg für die zu waschende Bahn 1 definieren. Es versteht sich, daß die Führungskanten abgerundet und so ausgebildet sind, daß die mechanische Beanspruchung der Bahn 1 gering bleibt.The web 1 fed through the insertion opening 3 is subjected to largely used washing water which runs over the lowest collecting surface 17 and forms a strong vortex in the area of the associated guide edges, which at least loosens dirt particles adhering to the web 1, but also partially takes them along. When the web, which is essentially smoothly stretched between the leading edges 18, reaches the area of the next leading edge, it is already washed with less soiled washing water. This continues on the vertical path of the web 1 through the device, whereby strong vortices arise in the area of the leading edges 18, which effectively support the laundry. Finally, the web 1 passes into the region of the W aschdüsenanordnungen 6.7 and is loaded there with pure washing water. The washing action is based on the one hand on the action of the jets emerging from the nozzles 12 and on the other hand on the formation of eddies in the area of the guide edges 13, 14 of these washing nozzle arrangements. Thereafter, the web is largely cleaned so that it can be guided out of the device on wipers 23, 24, which delimit the upper outlet opening 4. It has been shown that at a total height of approximately 0.6 meters of the device, high web speeds are possible without the washing effect being impaired. It has been found that the washing effect is improved with increasing web speed. This may be due to the influence of the web on the Position of the figure has two housing walls 15, 16, which are essentially mirror images. In the upper housing sections enclosing the washing nozzle arrangements 6, 7, the walls have an approximately trapezoidal cross section. The lower trapezoidal surfaces define collecting surfaces 17, which end at guide edges 18 in the region of the path of the web 1. Essentially horizontal wall sections 19 adjoin the guide edges 18, from which, in turn, collecting surfaces 17 with subsequent guide edges 18 are inclined to the horizontal, preferably at an angle of 45 degrees. The result is the sawtooth-shaped configuration shown in the figure, in which the collecting surfaces 17 and the guide edges 18 of the two housing walls 15, 16 are offset from one another in the vertical direction. The arrangement in detail is such that the leading edges 18 of the collecting surfaces 17 as well as the edges 13, 14 of the washing nozzle arrangements 6, 7 define a zigzag path for the web 1 to be washed. It is understood that the guide edges are rounded and designed so that the mechanical stress on the web 1 remains low.

Am unteren Ende bilden die Gehäusewandungen 15, 16 Sammelbehälter 20 mit jeweils einem nicht dargestellten Wasserabfluß. Jeder Sammelbehälter 20 weist ein schräggestelltes Bodenblech 21 auf, das an einem die Eintrittsöffnung 3 begrenzenden und an der entsprechenden Seite der Bahn 1 anliegenden Abstreifer 22 endet.At the lower end, the housing walls 15, 16 form collecting containers 20, each with a water drain, not shown. Each collecting container 20 has an inclined bottom plate 21, which ends at a scraper 22 which delimits the inlet opening 3 and lies against the corresponding side of the web 1.

Man erkennt, daß das aus den Waschdüsenanordnungen 6,7 austretende Waschwasser kaskadenartig über die einzelnen Sammelflächen 17 bis in die Sammelbehälter 20 läuft, aus denen es dann abgeführt wird. Während das Wasch-Zum besseren Verständnis der Funktionsweise wird zunächst der obere Teil der Vorrichtung mit der letzten Waschstufe beschrieben. Im oberen Teil der Vorrichtung befinden sich zwei Waschdüsenanordnungen 6,7 die an eine oder mehrere nicht dargestellte Pumpen angeschlossen sind, die Waschdüsenanordnungen 6,7 sind auf unterschiedlichen Seiten der Bahn 1 angeordnet und bestehen jeweils aus kastenförmigen Körpern 8,9, deren Länge wenigstens der Breite der zu waschenden Bahn 1 entspricht. Auf der der Bahn 1 zugewandten Seite werden die Körper 8 von jeweils zwei Wandungen 9,10 begrenzt, die unter einem Winkel zueinander angeordnet sind und auf dieser Seite eine Ausnehmung 11 mit im wesentlichen dreieckförmigen Querschnitt difinieren. Dort, wo die beiden Wandungen 9,10 im Tiefsten der Ausnehmung 11 aneinander stoßen, sind Düsen 12 ausgebildet, aus denen das zugeführte Wasser in Richtung auf die zu waschende Bahn 1 austreten kann. Bei den Düsen 12 kann es sich um eine Breitschlitzdüse handeln, die sich über die gesamte Länge des Körpers 8 erstreckt, es kann sich aber auch um eine Reihe von einzelnen Düsen handeln.It can be seen that the washing water emerging from the washing nozzle arrangements 6, 7 runs in a cascade manner over the individual collecting surfaces 17 into the collecting container 20, from which it is then discharged. While the washing To better understand the mode of operation, the upper part of the device with the last washing stage is described first. In the upper part of the device there are two washing nozzle arrangements 6, 7 which are connected to one or more pumps, not shown, the washing nozzle arrangements 6, 7 are arranged on different sides of the web 1 and each consist of box-shaped bodies 8, 9, the length of which is at least that Width of the web 1 to be washed corresponds.
