Description

Die Erfindung betrifft einen Foulard mit einer Umschlingungswalze für eine zu behandelnde textile Warenbahn mit einem Trog zur Aufnahme einer Flotte, die aus dem Trog dosiert an die an der Umschlingungswalze anliegende Warenbahn abgegeben wird, wobei eine Rakel durch Magnetkraft an der Umschlingungswalze anliegend gehalten ist und ggf. Leitwalzen für die Warenbahn vorgesehen sind.The invention relates to a foulard with a wrapping roller for a textile web to be treated with a trough for receiving a liquor, which is metered from the trough to the web lying against the wrapping roller, a doctor blade being held against the wrapping roller by magnetic force and possibly Guide rollers are provided for the web.

Einen solchen Foulard beschreibt die AT-A-360 485. Dort taucht die drehbar gelagerte Rakel mit ihrem unteren Teil in die in dem Trog befindliche Flotte ein. Ihr oberer Teil liegt an der Warenbahn an, die in diesem Bereich wiederum über Leitwalzen längs einer vorgegebenen Strecke an der Umschlingungswalze anliegend gehalten wird. Die Flotte wird dort also aus dem Trog über die Rakel auf die Außenfläche der Warenbahn übertragen. Dadurch bedingt, daß die Rakel mit Magnetkraft an der Umschlingungswalze anliegend gehalten wird, ergibt sich ein über die Länge der Rakel konstant schmaler Spalt für den Flottenauftrag. Für viele Anwendungsfälle ist dieser Flottenauftrag aber immer noch unnötig hoch.Such a foulard is described in AT-A-360 485. There, the rotatably mounted doctor blade dips with its lower part into the fleet located in the trough. Its upper part rests on the web, which in this area is in turn held against the wrapping roller over guide rollers along a predetermined distance. The fleet is therefore transferred from the trough via the doctor blade to the outer surface of the web. Due to the fact that the doctor blade is held in contact with the wrapping roller with magnetic force, there is a gap for the fleet application which is constant over the length of the doctor blade. For many applications, however, this fleet order is still unnecessarily high.

In vielen Fällen, wie z. B. beim Fixieren von Farbstoffen nach Zweiphasen-Verfahren, ist es wichtig, zur Erzielung eines scharfen Standes der Konturen sowie zur Vermeidung von Abflekkungen auf den Weißfond nur geringe Flottenmengen auf das bedruckte Material, beispielsweise textile Gewebe und Gewirke, aufzutragen. Damit die Drucke beim Fixierprozeß nicht fließen, werden den Fixierflotten hohe Mengen an anorganischen Salzen, die die Löslichkeit der Farbstoffe herabsetzen, zugesetzt. Die wirklich zur Farbstoffixierung notwendige Flüssigkeitsmenge ist aber erheblich niedriger als die mit den üblichen Methoden, z. B. mit einem Foulard aufgebrachte Gesamtflüssigkeit. Die Möglichkeit, nur die benötigten geringen Flüssigkeitsmengen aufzutragen, würde somit nicht nur eine Ersparnis an eingesetzten Chemikalien bedeuten, sondern darüber hinaus eine erhebliche Verringerung der Abwasserbelastung durch die überschüssige Flotte.In many cases, such as B. when fixing dyes by two-phase processes, it is important to apply only small amounts of liquor to the printed material, for example textile fabrics and knitted fabrics, to achieve a sharp state of the contours and to avoid reflections on the white background. So that the prints do not flow during the fixing process, large amounts of inorganic salts are added to the fixing liquors, which reduce the solubility of the dyes. The amount of liquid really necessary for dye fixation is considerably lower than that with the usual methods, e.g. B. applied with a foulard total liquid. The option of applying only the small amounts of liquid required would not only mean a saving in the chemicals used, but also a significant reduction in the wastewater pollution caused by the excess liquor.

Auch bei anderen Arbeitsprozessen, beispielsweise bei der Warenvorbehandlung oder bei Appreturprozessen, ist es günstig, nur geringe Flottenmengen aufzutragen, da man in den nachfolgenden Trocknungsschritten wesentlich weniger Wasser verdampfen muß und damit den Energieverbrauch erheblich senken kann bzw. bei den folgenden Waschvorgängen eine erhebliche Reduzierung der Abwasserbelastung erreicht.Also in other work processes, for example in the pretreatment of goods or finishing processes, it is advantageous to apply only small amounts of liquor, since in the subsequent drying steps, much less water has to be evaporated and thus the energy consumption can be reduced considerably, or in the subsequent washing processes a significant reduction in Waste water pollution reached.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Foulard vorzuschlagen, mit dem eine einstellbare und möglichst geringe Menge an Flotte gleichmäßig auf die im Foulard zu behandelnde Warenbahn dosiert aufgetragen werden kann.The invention is therefore based on the object of proposing a foulard with which an adjustable and as small a quantity of liquor as possible can be applied in a metered manner to the web to be treated in the foulard.

Ausgehend von einem Foulard der eingangs genannten Art gelingt dies gemäß der Erfindung dadurch, daß die Flottenübertragung vom Trog auf die Umschlingungswalze und von dieser auf die Warenbahn erfolgt, daß die Rakel unmittelbar am Umfang der Umschlingungswalze anliegt, und zwar in Transportrichtung der Flotte vor derjenigen Stelle, an der die Warenbahn die Umschlingungswalze berührt, und daß an der an der Umschlingungswalze anliegenden Berührungsfläche der Rakel eine Vielzahl von nebeneinander liegenden Aussparungen angebracht ist.Starting from a foulard of the type mentioned, this is achieved according to the invention in that the liquor is transferred from the trough to the wrapping roller and from this to the web, that the doctor blade is in direct contact with the circumference of the wrapping roller, in the transport direction of the fleet in front of that point , on which the web touches the wrapping roller, and in that a plurality of adjacent recesses is provided on the contact surface of the doctor blade which is in contact with the wrapping roller.

Die Flotte hat somit ausreichend Zeit, sich nach ihrem Übertrag vom Trog auf die Umschlingungswalze auf der Oberfläche der Umschlingungswalze gleichmäßig zu verteilen. Vor dem Auftrag der Flotte vom Umfang der Umschlingungswalze auf die Warenbahn wird der am Umfang der Umschlingungswalze anhaftende Flottenfilm durch die dort anliegende Rakel mit ihren Aussparungen fein dosiert. Die Aussparungen wirken als Durchlässe für die Flotte, während die Flotte im Bereich zwischen den Aussparungen praktisch nicht durchgelassen wird, und zwar über die ganze Länge der Rakel bzw. der Umschlingungswalze. Für die Aussparungen genügt im allgemeinen eine Tiefe von einigen Hundertstel Millimetern. Die Tiefe und die Breite der Aussparungen werden entsprechend dem jeweiligen Verwendungszweck gewählt, so daß für jeden Verwendungszweck eine optimal angepaßte Rakel zur Verfügung steht. Über die zwischen den Rakel und der Auftreffstelle der Warenbahn an der Umschlingungswalze kann sich der Flottenfilm auf der Umschlingungswalze abermals vergleichmäßigen.The fleet thus has sufficient time to be distributed evenly on the surface of the wrapping roller after it has been transferred from the trough to the wrapping roller. Before the fleet is applied from the circumference of the wrapping roller to the web, the liquor film adhering to the circumference of the wrapping roller is finely metered by the doctor blade with its recesses there. The cutouts act as passages for the liquor, while the liquor is practically not let through in the area between the cutouts, specifically over the entire length of the doctor blade or the wrapping roller. A depth of a few hundredths of a millimeter is generally sufficient for the cutouts. The depth and the width of the recesses are selected in accordance with the respective intended use, so that an optimally adapted doctor blade is available for each intended use. The liquor film on the wrapping roller can be evened out again via the between the doctor blade and the point of impact of the material web on the wrapping roller.

Zur Erzielung der magnetischen Anziehungskraft zwischen der Rakel und der Umschlingungswalze ist ein Magnet in der Umschlingungswalze unter deren Oberfläche im Bereich der Rakel vorgesehen, der sich über die Länge der Rakel erstreckt. Der Magnet kann ein Permanentmagnet sein oder ein Elektromagnet. Wird ein Elektromagnet verwendet, so hat dieser vorzugsweise eine einstellbare Magnetkraft. Auch die Magnetkraft eines Permanentmagneten kann eingestellt werden, beispielsweise durch Verändern des Abstandes des betreffenden Poles des Permanentmagneten von der Rakel.To achieve the magnetic attraction between the doctor blade and the wrapping roller, a magnet is provided in the wrapping roller below its surface in the area of the doctor blade, which extends over the length of the doctor blade. The magnet can be a permanent magnet or an electromagnet. If an electromagnet is used, it preferably has an adjustable magnetic force. The magnetic force of a permanent magnet can also be adjusted, for example by changing the distance of the relevant pole of the permanent magnet from the doctor blade.

Zu diesem Zweck wird es bevorzugt, wenn der Magnet in Umfangsrichtung der Umschlingungswalze einstellbar ist, wodurch dann die Magnetkraft bei ortsfester Rakel ebenfalls eingestellt wird.For this purpose, it is preferred if the magnet can be adjusted in the circumferential direction of the wrapping roller, as a result of which the magnetic force is then also set in the case of a fixed doctor blade.

Falls ein Flachrakel verwendet wird, soll diese mit einer kammartig profilierten Berührungsfläche ausgebildet sein.If a flat doctor blade is used, it should be designed with a comb-like profiled contact surface.

Im Fall einer Rundrakel soll diese eine gewindeförmige Profilierung haben, weil diese leichter herzustellen ist als eine auch mögliche Profilierung mit tangential verlaufenden Nuten.In the case of a circular doctor blade, this should have a thread-like profile because it is easier to manufacture than a possible profile with tangential grooves.

Es fördert die Lösung der Erfindungsaufgabe, wenn an der Umschlingungswalze wenigstens eine Auflagewalze mit einstellbarem Anpreßdruck anliegt. Die Auflagewalze ist vorzugsweise in Umfangsrichtung der Umschlingungswalze einstellbar. Sie kann leicht an die Saugfähigkeit des Textilguts angepaßt werden. Dadurch ist eine weitere Beeinflussung der übertragenen Flüssigkeitsmenge möglich, indem nach einer mehr oder weniger langen Verweilstrecke nach der Rakel, auf der sich der Flüssigkeitsfilm vergleichmäßigen kann, die Auflagewalze vorgesehen ist, an der das Textilgut die aufgebrachte Flüssigkeitsmenge in einem gewünschten Ausmaß, also mehr oder weniger vollständig, aufnimmt.It promotes the solution of the invention task, if at least one support roller with adjustable contact pressure is applied to the wrapping roller. The support roller is preferably adjustable in the circumferential direction of the wrapping roller. It can easily be adapted to the absorbency of the textile. This makes it possible to further influence the amount of liquid transferred by providing the support roller on which the textile material has the amount of liquid applied to a desired extent, i.e. more or after a more or less long dwell after the doctor blade, on which the liquid film can even out less complete, absorbs.

Auch die Auflagewalze kann mit Magnetkraft an der Umschlingungswalze gehalten sein.The support roller can also be held on the wrapping roller with magnetic force.

Der Anpreßdruck der Auflagewalze kann durch ein an ihr angreifendes Pneumatiksystem einstellbar sein.The contact pressure of the support roller can be set by a pneumatic system acting on it.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen näher erläutert, aus denen sich weitere wichtige Merkmale ergeben. Es zeigt

The invention is explained in more detail below on the basis of exemplary embodiments, from which further important features result. It shows
  • Figure 1 is a view of a flat doctor blade according to the invention.
  • Figure 2 is a view of a circular doctor blade according to the invention.
  • Fig. 3 shows schematically a side view of a foulard according to the invention.

Zunächst sei der grundsätzliche Aufbau des neuartigen Foulards anhand von Fig. 3 beschrieben.First, the basic structure of the novel foulard is described with reference to FIG. 3.

Über eine Leitwalze 1 wird eine textile Warenbahn 2 einer Umschlingungswalze 3 zugeführt. Die Umschlingungswalze 3 taucht in einen Trog 6 mit stufenlos regelbarem Flottenniveau ein. Durch eine Rakel 4 nach Fig. 1 oder 2 wird die mitgenommene, überschüssige Flotte abgenommen. Je nach Ausführung der Rakel verbleibt eine definierte Menge an Flotte auf der Umschlingungswalze 3, welche auf die textile Warenbahn übertragen wird.A textile fabric web 2 is fed to a wrapping roller 3 via a guide roller 1. The wrapping roller 3 dips into a trough 6 with a continuously adjustable fleet level. The excess liquor taken along is removed by a doctor 4 according to FIG. 1 or 2. Depending on the design of the doctor blade, a defined amount of liquor remains on the wrapping roller 3, which is transferred to the textile web.

Die Rakel 4 wird durch einen Magneten 5 an die Umschlingungswalze 3 angepreßt. Der Magnet ist ein Permanentmagnet oder ein Elektromagnet. Die Rakel besteht daher aus einer Eisenlegierung.The doctor blade 4 is pressed against the wrap roller 3 by a magnet 5. The magnet is a permanent magnet or an electromagnet. The doctor blade is therefore made of an iron alloy.

Durch Auflagewalzen 7 wird die textile Warenbahn an die Umschlingungswalze 3 gedrückt, wobei der Auflagedruck der Auflagewalzen ebenfalls durch einen Magneten 8 oder durch ein Pneumatiksystem erzeugt wird.The textile fabric web is pressed against the wrapping roller 3 by support rollers 7, the support pressure of the support rollers also being generated by a magnet 8 or by a pneumatic system.

Über eine Leitwalze 9 wird die textile Warenbahn von der Umschlingungswalze 3 abgenommen.The textile material web is removed from the wrapping roller 3 via a guide roller 9.

Wie in Fig. 3 gezeigt, wird die textile Warenbahn 2 über die Leitwalze 1 der im Gegenuhrzeigersinn drehenden Umschlingungswalze 3 zugeführt, wobei die durch die Umschlingungswalze mitgenommene überschüssige Flottenmenge durch die Rakel 4 nach Fig. 1 oder 2 abgestreift wird. Die Anpreßwalzen 7 sowie die Rakel 4 werden durch die Magnete 8, 5 an die Umschlingungswalze 3 gepreßt.As shown in Fig. 3, the textile web 2 is fed via the guide roller 1 to the counterclockwise wrap roller 3, the excess liquor entrained by the wrap roller being wiped off by the doctor blade 4 according to Fig. 1 or 2. The pressure rollers 7 and the squeegee 4 are pressed by the magnets 8, 5 to the wrapping roller 3.

Es besteht die Möglichkeit, den Anpreßdruck der Aufliegewalzen 7 bzw. der Rakel 4 zu verändern durch Verschwenken der Magnete 5, 8 dergestalt, daß der magnetische Zenit des betreffenden Magneten zu den Walzen bzw. Rakeln versetzt wird. Das Verschwenken der Magnete geschieht mittels einer besonderen Verstellvorrichtung in Richtung und im Winkelbereich der Pfeile 12.It is possible to change the contact pressure of the support rollers 7 or the doctor blade 4 by pivoting the magnets 5, 8 in such a way that the magnetic zenith of the magnet in question is displaced to the rollers or doctor blades. The magnets are pivoted by means of a special adjusting device in the direction and in the angular region of the arrows 12.

Der Anpreßdruck der Aufliegewalzen 7 läßt sich zudem durch Veränderung der angebrachten Walzenzahl variieren. Weiterhin können die Aufliegewalzen verschwenkt werden, um ein früheres oder späteres Anpressen der Ware an die Umschlingungswalze 3 zu erreichen.The contact pressure of the support rollers 7 can also be varied by changing the number of rollers attached. Furthermore, the lay-on rollers can be pivoted in order to achieve an earlier or later pressing of the goods onto the wrapping roller 3.

Es besteht auch die Möglichkeit, die Umschlingung der Walze 3 zu variieren durch Verändern der Positionen der Leitwalzen 1 und 9, wodurch sich ebenfalls eine Einstellung in der aufgenommenen Flottenmenge erreichen läßt.There is also the possibility of varying the wrapping of the roller 3 by changing the positions of the guide rollers 1 and 9, which can also achieve an adjustment in the amount of liquor taken up.

Die Magnete sind zum Beispiel Permanentmagnete oder Elektromagnete, um die Anpreßkräfte der Rakel bzw. Aufliegewalzen an die Umschlingungswalze einstellen zu können.The magnets are, for example, permanent magnets or electromagnets, in order to be able to adjust the contact pressure of the doctor blade or lay-on roller to the wrapping roller.

Es kann eine Reinigungsvorrichtung 10 für die Umschlingungswalze vorgesehen sein, die kontinuierlich die Verunreinigungen der Umschlingungswalze hinter der Leitwalze 9 entfernt.A cleaning device 10 for the wrapping roller can be provided, which continuously removes the impurities from the wrapping roller behind the guide roller 9.

Dem beschriebenen Foulard kann z. B. ein Dämpfer, ein Trockengerät oder eine andere Nachfolgemaschine nachgeschaltet werden.The foulard described can, for. B. a damper, a dryer or another successor can be connected.

Die kammartigen Einschnitte der Flachrakel nach Fig. 1 sind einige hundertstel Millimeter tief. Durch die Variationsmöglichkeiten der Spalttiefe sowie des Verhältnisses der Breite der Stege zur Spaltbreite kann hierbei die Flottenmenge dosiert werden. Dasselbe gilt für die Einschnitte der Rundrakel nach Fig. 2.The comb-like incisions of the flat doctor blade according to FIG. 1 are a few hundredths of a millimeter deep. The amount of liquor can be metered through the variation possibilities of the gap depth and the ratio of the width of the webs to the gap width. The same applies to the incisions of the circular doctor blade according to FIG. 2.

Im Falle einer Rundrakel nach Fig. 2 kann eine Walze mit eingeschnittenem Gewinde oder einem aufgewickelten Draht Verwendung finden, wobei der Draht zweckmäßig in Form einer Schraubenlinie angeordnet ist. Es kann auch eine entsprechend gravierte Walze eingesetzt werden. Es ist weiterhin möglich, auf eine Walze Ringe aufzuschieben, die zweckmäßig schräg angeordnet sind, damit ein gleichmäßiger Flüssigkeitsauftrag erfolgf. Auch hier sind Variationsmöglichkeiten gegeben durch Ausgestaltung von Ganghöhe und Gangtiefe des Gewindes sowie bei der Ausgestaltung des Gewindes als Trapezgewinde durch die Ausdehnung der oberen Begrenzungslinie des trapezförmigen Querschnitts. Fig. 2 zeigt eine schematische Ansicht einer solchen Rundrakel mit eingeschnittenem Gewinde.In the case of a circular doctor blade according to FIG. 2, a roller with a cut thread or a wound wire can be used, the wire being expediently arranged in the form of a helical line. An appropriately engraved roller can also be used. It is also possible to slide rings onto a roller, which are suitably arranged obliquely so that a uniform application of liquid takes place. Here, too, there are possibilities for variation by designing the pitch and depth of the thread and, in the case of the thread being designed as a trapezoidal thread, by extending the upper boundary line of the trapezoidal cross section. Fig. 2 shows a schematic view of such a circular doctor blade with a cut thread.

Die Flachrakel nach Fig. 1 kann stationär angebracht sein oder - zur gleichmäßigen Übertragung des Feuchtigkeitsfilms - hin- und herbewegt werden.The flat doctor blade according to FIG. 1 can be attached stationary or can be moved back and forth for the uniform transfer of the moisture film.

/ Die Rundrakel gemäß Fig. 2 kann von der Umschlingungswalze mitgenommen oder selbständig angetrieben werden. Im letzteren Fall kann die Umfangsgeschwindigkeit der Rundrakel etwa derjenigen der Umschlingungswalze entsprechen oder davon verschieden sein, also langsamer oder schneller laufen. Auch ein gegenläufiger Antrieb der Rundrakel ist möglich. / The circular doctor blade according to FIG. 2 can be carried along by the wrapping roller or driven independently. In the latter case, the circumferential speed of the circular doctor blade can be about that of the wrapping roller speak or be different, i.e. run slower or faster. Reverse drive of the circular doctor blade is also possible.
