Description

Die Erfindung bezieht sich auf eine Vorrichtung zum gleichmäßigen Auftragen einer minimalen Menge eines Behandlungs- wie Veredelungsfluids auf eine vorbeilaufende, eine gewisse Breite aufweisende textile Warenbahn mit einem quer zur Warenbahn ausgerichteten Auftragsbalken, welcher einen sich über die Breite der Warenbahn erstreckenden, gegen die Warenbahn gerichteten offenen Schlitz aufweist, dem das Fluid gleichmäßig über die Arbeitsbreite der Warenbahn zugeführt ist, und mit einer dem Schlitz auf der anderen Seite der Warenbahn gegenüberliegenden Abstützung für die Warenbahn.The invention relates to a device for uniformly applying a minimal amount of a treatment and finishing fluid to a passing textile web having a certain width, with an order bar oriented transversely to the web, which extends across the width of the web and is directed towards the web has an open slot, to which the fluid is fed uniformly over the working width of the web, and with a support for the web opposite the slot on the other side of the web.

Eine Vorrichtung dieser Art ist durch die DE 33 15 770 A1 bekannt. Die Abstützung besteht aus einem elastisch nachgiebigen, geschlossenen Kissen, das den Schlitz und einen größeren Bereich seitlich neben dem Schlitz abdeckt, um die aus dem Schlitz austretende Flüssigkeit ohne Verlust in die Warenbahn zu bringen.A device of this type is known from DE 33 15 770 A1. The support consists of an elastically flexible, closed cushion that covers the slot and a larger area to the side of the slot in order to bring the liquid emerging from the slot into the web without loss.

Neben dieser Art von Auftragsvorrichtung sind außer den Aufgießvorrichtungen nur noch die Siebdruckvorrichtungen bekannt, bei denen die Abstützung aus einem horizontalen Sieb- ggf. mit Absaugung oder einem dichten Endlosband, aber auch aus einer Walze bestehen kann, die die Warenbahn am Schlitz vorbei trägt. Hier ist beispielsweise die DE 34 19 367 A1 zu nennen. Wesentlich bei Siebdruckmaschinen ist aber, daß der Schlitz von einem sich drehenden Siebzylinder umgeben ist, durch dessen Perforation die Flüssigkeit zur Herstellung eines Musters gedrückt werden soll. Um solche Vorrichtungen geht es beim Anmeldungsgegenstand aber nicht, vielmehr soll eine Vorrichtung gefunden werden, mit der eine Minimalmenge der Flüssigkeit gleichmäßig über die Arbeitsbreite auf die Warenbahn aufgetragen und optimal in die Oberfläche wie Flor eingedrückt werden kann, um gerade nur die Warenbahnoberfläche vollständig zu tränken.In addition to this type of application device, in addition to the pouring devices, only the screen printing devices are known in which the support can consist of a horizontal screen, possibly with suction or a dense endless belt, but also of a roller which carries the web past the slot. For example, DE 34 19 367 A1 should be mentioned here. It is essential in screen printing machines, however, that the slot is surrounded by a rotating screen cylinder, through the perforation of which the liquid is to be pressed to produce a pattern. Such devices are not the subject of the application, but rather a device is to be found with which a minimal amount of the liquid can be applied uniformly over the working width to the web and optimally pressed into the surface like pile to just completely soak the web surface .

Ausgehend von der Vorrichtung anfangs genannter Art besteht die Aufgabe der Erfindung darin, eine Vorrichtung zu finden, mit der die zur ausreichenden Netzung minimal notwendige Flüssigkeitsmenge nicht nur gleichmäßig über die Arbeitsbreite verteilt, sondern auch in die Faseroberfläche der Warenbahn wie in den Flor od. dgl. penetriert wird.Starting from the device initially mentioned, the object of the invention is to find a device with which the minimum amount of liquid required for sufficient wetting is not only distributed evenly over the working width, but also in the fiber surface of the web as in the pile or the like is penetrated.

Zur Lösung der gestellten Aufgabe sieht die Erfindung vor, daß die Abstützung als parallel zum Auftragsbalken ausgerichtete Druckwalze ausgebildet ist, die - über die dazwischen vorbeilaufende Warenbahn - gegen die beiden den Schlitz begrenzenden Längskanten gedrückt ist. Der Grund für diese Konstruktion ist die wünschenswerte Erholung des Flors nach der Komprimierung durch den Druck der Walze, damit die Fasern auch die notwendige Flüssigkeitsmenge wurzeltief aufnehmen, gleich anschließend soll aber die Warenbahn zur Reduzierung auf die nur minimal notwendige Flüssigkeitsmenge wieder abgequetscht werden. Diese drei Vorgänge: Komprimierung, Aufatmung und wieder Komprimierung des Flors sind bei der Vorrichtung nach der Erfindung unmittelbar hintereinander geschaltet, so daß der gewünschte sparsame Fluidminimalauftrag bez. -verbrauch gewährleistet ist.To achieve the object, the invention provides that the support is designed as a pressure roller which is aligned parallel to the application bar and is pressed against the two longitudinal edges delimiting the slot, via the web of material passing therebetween. The reason for this construction is the desirable recovery of the pile after the compression by the pressure of the roller so that the fibers also absorb the necessary amount of liquid down to the roots, but immediately afterwards the web is to be squeezed off again to reduce it to the minimally necessary amount of liquid. These three processes: compression, respiration and again compression of the pile are connected in series in the device according to the invention, so that the desired economical fluid minimum order. -consumption is guaranteed.

Der Abstand der Längskanten des Schlitzes hängt von der Art und dem Volumen der zu behandelnden Ware ab. Jedenfalls soll die an der Walze zusammengedrückte Oberfläche der Warenbahn sich wieder aufrichten, aufatmen, dabei die Flüssigkeit aufsaugen können und dann wieder zusammengequetscht werden, damit nur die wirklich notwendige Flüssigkeitsmenge im Flor verbleibt. Es ist daran gedacht, den Abstand der Längskanten des Schlitzes in der Größenordnung der doppelten Länge des jeweiligen Flors der Warenbahn zu bemessen. Der Schlitz kann aber auch breiter sein.The distance between the longitudinal edges of the slot depends on the type and volume of the goods to be treated. In any case, the surface of the web pressed together on the roller should straighten up again, breathe freely, be able to absorb the liquid and then be squeezed together so that only the really necessary amount of liquid remains in the pile. It is contemplated to measure the distance between the longitudinal edges of the slot in the order of twice the length of the respective pile of the web. The slot can also be wider.

Wesentlich ist auch die gleichmäßige Zuführung des Behandlungsfluids in und über die Breite des Schlitzes. Für diese Aufgabe gibt es eine gute Lösung nach der DE 40 26 198 A1. Deshalb wird auch bei der Vorrichtung nach der Erfindung vorgeschlagen, daß der Schlitz mit einer Flüssigkeitsverteileinrichtung verbunden ist, bei der die Verteilung der Flüssigkeit von einer Zuflußleitung bis zu einer Vielzahl von Ausflußöffnungen schrittweise derart vorgesehen ist, daß die Zuflußöffnung beidseitig in Arbeitsbreitenrichtung mit einer gleich langen ersten Verzweigleitung verbunden ist, an deren jeweiligem Ende eine Zwischenausflußöffnung vorgesehen ist, an die sich in gleicher Weise beidseitig in Arbeitsbreitenrichtung eine jedoch um die Hälfte der ersten Verzweigleitung kürzere und im Querschnitt verkleinerte zweite Verzweigleitung anschließt, sich die Flüssigkeitsverteilung in dieser Flüssigkeitsverteileinrichtung also stammbaumähnlich mehrfach verzweigt, und daß somit die fein über die Arbeitsbreite verteilten Ausflußöffnungen in den sich über die Arbeitsbreite der Warenbahn erstreckenden Schlitz münden.It is also essential that the treatment fluid is fed uniformly into and across the width of the slot. There is a good solution for this task according to DE 40 26 198 A1. Therefore, it is also proposed in the device according to the invention that the slot is connected to a liquid distribution device, in which the distribution of the liquid is gradually provided from an inflow line to a plurality of outflow openings such that the inflow opening is of equal length on both sides in the working width direction is connected first branch line, at the respective end of which an intermediate outflow opening is provided, to which the same A second branch pipe, shorter by half of the first branch pipe and reduced in cross-section, connects on both sides in the working width direction, so that the liquid distribution in this liquid distribution device is branched several times like a family tree, and thus that the outflow openings, which are finely distributed over the working width, enter the working width of the web extending slot open.

Die Fluidauftragsvorrichtung nach Fig. 1 besteht aus einem Rahmen 1, an dem eine Reihe von Umlenkwalzen 3 - 11 zur Führung der Warenbahn 2 in die jeweilige Behandlungsstation drehbar gelagert sind. Die Laufrichtung der Warenbahn ist mit dem Pfeil 12 angedeutet. Von der oben im Rahmen 1 gelagerten Umlenkwalze 5 verläuft die Warenbahn 2 schräg rückwärts abwärts zur Umlenkwalze 6. Die mit dem Flor in der Fig. 1 nach rechts gerichtete Warenbahn hat also eine Neigung nach unten, worauf weiter unten eingegangen wird. Etwa in der Mitte zwischen den Walzen 5 und 6 ist die Auftragsvorrichtung 13 angeordnet. Sie besteht - auch gemäß Fig 2 - aus einem auf der Florseite der Warenbahn 2 angeordneten Auftragsbalken 14, mit der in Fig. 3 dargestellten Flüssigkeitsverteileinrichtung 15, und aus einer auf der Rückseite der Warenbahn 2 angeordneten Druckwalze 16, die dem Auftragsbalken 14 zentrisch zugeordnet ist. Der Auftragsbalken 14 mit der Druckwalze 16 sind mit ihrer Wirkungsachse 17 senkrecht zur Warenbahn 2 ausgerichtet, also ebenfalls rückwärts geneigt.The fluid application device according to FIG. 1 consists of a frame 1, on which a row of deflecting rollers 3-11 are rotatably mounted for guiding the material web 2 into the respective treatment station. The direction of travel of the web is indicated by arrow 12. From the deflection roller 5 mounted above in the frame 1, the web 2 runs obliquely backwards downwards to the deflection roller 6. The web that is directed to the right in FIG. 1 thus has a downward slope, which will be discussed further below. The application device 13 is arranged approximately in the middle between the rollers 5 and 6. It consists - also according to FIG. 2 - of an order bar 14 arranged on the pile side of the web 2, with the liquid distribution device 15 shown in FIG. 3, and of a pressure roller 16 arranged on the back of the web 2, which is centrally assigned to the order bar 14 . The application bar 14 with the pressure roller 16 are aligned with their axis of action 17 perpendicular to the web 2, that is also inclined backwards.

Der Auftragsbalken 14 weist an der der Warenbahn zugeordneten Seite einen Schlitz 18 auf, durch den die Auftragsflüssigkeit auf die Warenbahn 2 gedrückt wird. Der Schlitz hat an der Auftrittsseite zwei Längskanten 19, 20, die sich über die Arbeitsbreite des Auftragsbalkens 14 erstrecken. Die Höhe des Schlitzes 18 ergibt sich gemäß Ausführungsbeispiel aus der im Querschnitt halbkreisförmigen Gestaltung. Die auf der anderen Seite der Warenbahn 2 zentrisch zum Schlitz 18 angeordnete Druckwalze 16 liegt - über die Warenbahn 2 - an den Längskanten 19, 20 des Schlitzes 18 an. Auf diese Weise wird der Flor 2' der Warenbahn 2 beim Durchlauf durch die Auftragsvorrichtung 13 zunächst an der Längskante 19 komprimiert, entlüftet, dann im Schlitz 18 nach dem oder beim Aufrichten mit der jeweiligen Auftragsflüssigkeit genetzt und dann wieder an der Längskante 20 komprimiert, damit nur die minimal erforderliche Flüssigkeit in dem Flor 2' verbleibt.The order bar 14 has a slot 18 on the side assigned to the web, through which the application liquid is pressed onto the web 2. The slot has two longitudinal edges 19, 20 on the tread side, which extend over the working width of the application bar 14. According to the exemplary embodiment, the height of the slot 18 results from the semicircular design in cross section. The on the other side of the web 2 centrally arranged to the slot 18 pressure roller 16 is - on the web 2 - on the longitudinal edges 19, 20 of the slot 18. In this way, the pile 2 'of the web 2 is first compressed on the longitudinal edge 19 when passing through the application device 13, vented, then wetted in the slot 18 after or during erection with the respective application liquid and then compressed again on the longitudinal edge 20, so that only the minimally required liquid remains in the pile 2 '.

Damit die auf die Warenbahn 2 aufzutragende Flüssigkeit gleichmäßig über die Arbeitsbreite im Schlitz 18 verteilt geliefert wird, ist im Auftragsbalken 14 eine Verteilvorrichtung 15 vorgesehen, die aus Fig. 3 hervorgeht. Die Verteilung der Flüssigkeit erfolgt von einer Zuflußleitung 21, die jeweils mit einem Schlauch 21' für die Zufuhr der Flüssigkeit verbunden ist, bis zu einer Vielzahl von Ausflußöffnungen 22 schrittweise derart, daß die Zuflußöffnung 21 beidseitig in Arbeitsbreitenrichtung mit einer gleich langen ersten Verzweigleitung 23, 24 verbunden ist, an deren jeweiligem Ende eine Zwischenausflußöffnung 25, 26 vorgesehen ist, an die sich in gleicher Weise beidseitig in Arbeitsbreitenrichtung eine jedoch um die Hälfte der ersten Verzweigleitung 23, 24 kürzere und im Querschnitt verkleinerte zweite Verzweigleitung 27, 28 anschließt. Die Flüssigkeitsverteilung verzweigt sich folglich in dieser Flüssigkeitsverteileinrichtung 15 stammbaumähnlich. Die damit fein über die Arbeitsbreite verteilten Ausflußöffnungen 22 münden in den sich über die Arbeitsbreite der Warenbahn 2 erstreckenden Schlitz 18. Die einzelnen Leitungen und Öffnungen 21 - 28 in der Verteileinrichtung 15 sind in Blechen 29 gebildet, die zur Abdichtung der Leitungen lediglich aufeinandergepreßt sind.So that the liquid to be applied to the material web 2 is supplied evenly distributed over the working width in the slot 18, a distribution device 15 is provided in the order bar 14, which is shown in FIG. 3. The liquid is distributed from an inflow line 21, which is in each case connected to a hose 21 ′ for supplying the liquid, to a multiplicity of outflow openings 22 in such a way that the inflow opening 21 has an equally long first branch line 23 on both sides in the working width direction. 24 is connected, at the respective end of which an intermediate outflow opening 25, 26 is provided, which is followed in the same way on both sides in the working width direction by a second branch line 23, 24 which is shorter by half of the first branch line 23, 24 and has a reduced cross section. The liquid distribution consequently branches out in this liquid distribution device 15 like a family tree. The outflow openings 22, which are thus finely distributed over the working width, open into the slot 18 which extends over the working width of the web 2. The individual lines and openings 21 - 28 in the distribution device 15 are formed in metal sheets 29 which are only pressed together to seal the lines.

Der Auftragsbalken 14 ist um die Achse 30 mittels der am Rahmen 1 befestigten Druckzylindereinheit 31 in Richtung des Pfeiles verschwenkbar, so daß der Schlitz 18 nach unten ausgerichtet und z. B. gereinigt werden kann. Auch dazu ist die Druckwalze 16 von dem Auftragsbalken 14 weg verschwenkbar in der Halterung 32 mit dem Druckzylinder 33 im Rahmen 1 gelagert. Über diese Vorrichtung ist die Druckwalze 16 auch in ihrer Lage zum Schlitz 18 justierbar. Gleichfalls ist der Auftragsbalken 14 im Abstand zur Warenbahn 2 z. B. mittels der Vorrichtung 34 justierbar. Unterhalb der Auftragsvorrichtung 13 ertreckt sich im Bereich des Rahmens 1 eine Flüssigkeitsauffangwanne 35, die die Umlenkwalze 6 umgibt und dort die abtropfende oder abgestreifte Flüssigkeit auffängt und in den Nutzungskreislauf zurückführt.The order bar 14 is pivotable about the axis 30 by means of the pressure cylinder unit 31 attached to the frame 1 in the direction of the arrow, so that the slot 18 is oriented downwards and z. B. can be cleaned. For this purpose too, the printing roller 16 is pivotably mounted away from the application bar 14 in the holder 32 with the printing cylinder 33 in the frame 1. The pressure roller 16 can also be adjusted in its position relative to the slot 18 by means of this device. Likewise, the order bar 14 is at a distance from the web 2 z. B. adjustable by means of the device 34. Below the application device 13, in the area of the frame 1, extends a liquid collecting trough 35 which surrounds the deflecting roller 6 and there collects the dripping or stripped liquid and returns it to the cycle of use.
