Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Aufbringen von Farbmustern auf mindestens einen Dochtstrang aus lose zusammengefügten oder garnartig miteinander versponnenen Haaren und/oder Fasern und/oder Textilien mit einer Färbungsvorrichtung und einer Transportvorrichtung zum Bewegen des Dochtstranges relativ zur Färbungsvorrichtung, wobei die Einrichtung eine Verzögerungsvorrichtung aufweist, welche den von der Transportvorrichtung bewegten Dochtstrang unter Zugspannung versetzt. Eine gattungsgemäße Einrichtung zum Aufbringen von Farbmustern wird in dem Dokument WO 2004/038086 A1 offenbart.The present invention relates to a device for applying color patterns to at least one wick strand of loosely assembled or yarn-spun hairs and / or fibers and / or textiles with a dyeing device and a transport device for moving the wick strand relative to the dyeing device, the device having a retarding device which puts the wick strand moved by the transport device under tension. A generic device for applying color samples is in the document WO 2004/038086 A1 disclosed.

Dochtstränge aus lose zusammengefügten Haaren wie zum Beispiel Schafhaaren werden beim Stand der Technik mit der so genannten Vigoureux Bemusterungstechnik gefärbt. Es geht dabei um das Aufbringen von jeweils mehreren Querstreifen bzw. Anfärbungen auf jedes Haar. Der Streifenabstand und die Streifenbreiten bestimmen dabei die Farbintensität des später gezwirnten Fadens bzw. des fertigen Tuches. Durch das partielle Bedrucken wird eine Melange in der Struktur des fertigen Tuches erreicht. Die Dichte und damit die Anzahl der Anfärbungen pro Haar ist der Schlüssel für die spätere Qualitätsstufe des fertigen Tuches. Beim Stand der Vigoureux Technik werden für den Druckprozess Reliefdruckwalzen verwendet, die das Muster auf den Dochtstrang amboßieren. Die bisher bekannten Druckverfahren haben zwei wesentliche Nachteile. Zum einen ist eine häufige Reinigung der Druckeinrichtung erforderlich, um den Qualitätsstandart erhalten zu können. Zum anderen stößt man bei dem Wunsch der Erhöhung der Zahl der Anfärbungen pro Haar an technologische Grenzen.Wick strands of loosely assembled hair such as sheep hair are dyed in the prior art with the so-called Vigoureux sampling technique. It is about the application of each of several horizontal stripes or staining on each hair. The strip spacing and the strip widths determine the color intensity of the later twisted thread or of the finished cloth. Due to the partial printing a mélange is achieved in the structure of the finished cloth. The density and thus the number of stains per hair is the key to the later quality level of the finished cloth. At the booth of the Vigoureux technique, relief printing rollers are used for the printing process, which anvil the pattern on the wick strand. The previously known printing processes have two major disadvantages. On the one hand, frequent cleaning of the printing device is required in order to maintain the quality standard. On the other hand, the desire to increase the number of stains per hair meets technological limits.

Aufgabe der Erfindung ist es, eine gattungsgemäße Einrichtung dahingehend zu verbessern, dass möglichst viele Anfärbungen pro Haar möglich sind.The object of the invention is to improve a generic device to the effect that as many staining per hair are possible.

Dies wird erfindungsgemäß dadurch gekennzeichnet, dass die Transportvorrichtung ein, vorzugsweise von einer Antriebsvorrichtung angetriebenes, Transportrad mit einer an seinem Umfang, vorzugsweise durch Seitenführungsstege seitlich begrenzten, Führungsbahn für den Dochtstrang aufweist und dass die Färbungsvorrichtung im Bereich der Führungsbahn des Transportrades angeordnet ist und die Farbe auf den in der Führungsbahn des Transportrades gebogen bzw. gekrümmt geführten Dochtstrang aufbringt.This is inventively characterized in that the transport device has a, preferably driven by a drive device, transport wheel with a laterally limited at its periphery, preferably by side guide webs, guide path for the wick strand and that the dyeing device is arranged in the region of the guide rail of the transport wheel and the color on the in the guide rail of the transport wheel bent or curved guided wick strand applies.

Durch die mittels der Verzögerungsvorrichtung erreichte Zugspannung bzw. Vorspannung des Dochtstranges kommt es zu einer satten Auflage des Dochtstranges auf der Transportvorrichtung, wodurch eine gewisse Festigkeit in der Applikationszone, in der die Färbungsvorrichtung das Muster aufbringt, erreicht wird. Darüber hinaus werden eine geringfügige Streckung und ein Flachziehen des Dochtstranges in der Applikationszone erreicht, wodurch die Musterauftragung mit der Färbungsvorrichtung besonders präzise vorgenommen werden kann. Hierdurch ist es möglich, die Anzahl der Anfärbungen pro Haar zu erhöhen.The tensile stress or pretensioning of the wick strand achieved by means of the retarding device results in a rich support of the wick strand on the transport device, whereby a certain strength in the application zone in which the dyeing device applies the pattern is achieved. In addition, a slight stretching and a flat drawing of the Wick strand in the application zone is achieved, whereby the pattern application can be made very precisely with the coloring device. This makes it possible to increase the number of stains per hair.

Mit der erfindungsgemäßen Einrichtung können nicht nur lose zusammengefügte Haare und/oder Fasern und/oder Textilien angefärbt werden. Das gleiche ist auch für Dochtstränge aus garnartig miteinander versponnenen Haaren und/oder Fasern und/oder Textilien möglich. Insbesondere bei der Verwendung der erfindungsgemäßen Einrichtung zum so genannten Space-Dye-Prozess können mehrere bereits versponnene Garne des Dochtstranges so eng aneinander anliegend auf der Transportvorrichtung geführt werden, dass sie beim Applikationsprozess, also beim Einfärben, als Fläche erscheinen. Hierdurch wird die applizierte Farbe von den Garnen voll adsorbiert, wodurch keine Farbverluste entstehen.With the device according to the invention not only loosely assembled hair and / or fibers and / or textiles can be dyed. The same is also possible for wick strands of yarn-like spun together hair and / or fibers and / or textiles. In particular when using the device according to the invention for the so-called space-dye process, several already spun yarns of the wick strand can be guided so close to one another on the transport device that they appear as a surface during the application process, ie during inking. As a result, the applied color is fully adsorbed by the yarns, resulting in no color loss.

Um die beim Stand der Technik störende oben genannte Notwendigkeit der häufigen Reinigung der Färbungsvorrichtung zu beseitigen bzw. abzuschwächen, sieht ein weiterer Aspekt der Erfindung vor, dass die Färbungsvorrichtung zum Aufbringen, vorzugsweise Aufspritzen, von Farbe auf und/oder in den Dochtstrang ausgebildet ist, ohne dass hierzu ein physischer Kontakt zwischen Dochtstrang und Färbungsvorrichtung vorgesehen ist. Hierdurch wird eine kontaktlose Applikation der Farbe möglich, wodurch die beim Stand der Technik auftretenden Probleme mit der Reinigung der dort verwendeten Reliefdruckwalzen entfallen.In order to eliminate or mitigate the above-mentioned need for frequent cleaning of the dyeing device, which is objectionable in the prior art, a further aspect of the invention provides that the dyeing device is designed to apply, preferably spray-on, paint on and / or into the wicking strand, without this physical contact between the wick and dyeing device is provided. As a result, a contactless application of the ink is possible, which eliminates the problems occurring in the prior art with the cleaning of the relief printing rollers used there.

Um eine satte Auflage des Dochtstranges auf der Transportvorrichtung im Bereich der Applikationszone der Färbungsvorrichtung zu erreichen, ist es generell günstig, wenn die Transportvorrichtung eine, vorzugsweise im Bereich der Färbungsvorrichtung, gewölbte und/oder kanalförmig ausgebildete Führungsbahn für den Dochtstrang aufweist. Im in Fig. 1 gezeigten Ausführungsbeispiel wird dies erreicht, indem die Führungsvorrichtung und die Verzögerungsvorrichtung so ausgebildet sind, dass der Dochtsrang 1 auf einer im Wesentlichen omegaförmigen Bahn geführt ist. Die Transportvorrichtung weist ein, vorzugsweise von einer Antriebsvorrichtung angetriebenes, Transportrad 3 mit einer an seinem Umfang 10 durch Seitenführungsstege 5 seitlich begrenzten Führungsbahn 6 für den Dochtstrang 1 auf. Die Verzögerungsvorrichtung ist in diesem Ausführungsbeispiel ein, vorzugsweise vom Transportrad 3 angetriebenes, Einzugsrad 4. Dieses weist ebenfalls an seinem Umfang 10' eine durch Seitenführungsstege 5' begrenzte Führungsbahn 6' für den Dochtstrang 1 auf. Die gewünschte Zugspannung auf den Dochtstrang 1 wird erreicht, indem im Betrieb der Einrichtung die Umfangsgeschwindigkeit der Führungsbahn 6 des Transportrades 3 größer ist als die Umfangsgeschwindigkeit der Führungsbahn 6' des Einzugsrades 4. Vor ihrem Einzug mittels des Einzugsrades 4 liegen die Dochte frei in an sich bekannten Kardenkannen. Mehrere Dochte, beispielsweise zehn, werden bei ihrem Transport zum Einzugsrad 4 in einer hier nicht dargestellten aber an sich bekannten Ringführung zum Dochtstrang 1 vereint. Nach der Übergabe vom Einzugsrad 4 auf das Transportrad 3 wird der Dochtstrang 1 der durch die Färbungsvorrichtungen 2 definierten Applikationszone im leicht vorgespannten Zustand zugeführt. Hier erfolgt der Färbungsprozess. Anschließend übernimmt das Abnahmerad 8 den eingefärbten Dochtstrang 1 und übergibt ihn einem Förderband 9 zur weiteren Verarbeitung des Dochtstranges 1. Das Abnahmerad 8 ist günstigerweise frei laufend ausgebildet und weist einen eigenen Antrieb auf. Dadurch ist es möglich, die Transportgeschwindigkeit, mit der das Abnahmerad 8 den Dochtstrang 1 dem Förderband 9 zuführt, geringfügig höher oder gleich der Transportgeschwindigkeit des Transportrades 3 einzustellen. Zur Führung des Dochtstranges 1 weisen günstigerweise sowohl das Einzugsrad 4 als auch das Transportrad 3 als auch das Abnahmerad 8 an ihrem Umfang kanalförmige Ausnehmungen auf, wie sie in den Fig. 2 und 3 für das Einzugsrad 4 und Transportrad 3 dargestellt sind. Der Kanal wird dabei von den Führungsbahnen 6 und 6' sowie von den Seitenführungsstegen 5 und 5' gebildet. Die Drehrichtungen der drei genannten Räder sind in Fig. 1 durch die entsprechenden Pfeile veranschaulicht.In order to achieve a full coverage of the wicking strand on the transport device in the region of the application zone of the dyeing device, it is generally advantageous if the transporting device has an arched and / or channel-shaped guide path for the wicking strand, preferably in the region of the dyeing device. Im in Fig. 1 In the embodiment shown, this is achieved by designing the guiding device and the retarding device so that the wicking member 1 is guided on a substantially omega-shaped path. The transport device has a, preferably driven by a drive device, transport wheel 3 with a laterally limited on its circumference 10 by side guide webs 5 track 6 for the wick strand 1. The delay device is in this embodiment a, preferably driven by the transport wheel 3, feed wheel 4. This also has at its periphery 10 'by a side guide webs 5' limited guide track 6 'for the wick strand 1 on. The desired tension on the wick strand 1 is achieved by the peripheral speed of the guide track 6 of the transport wheel 3 is greater than the peripheral speed of the guide rail 6 'of the feed wheel 4 in the operation of the device. Before their introduction by means of the feed wheel 4, the wicks are free in itself known Karders. Several wicks, for example, ten, are united in their transport to the feed wheel 4 in a not shown here but known ring guide to the wick strand 1. After the transfer from the feed wheel 4 to the transport wheel 3, the wick strand 1 is fed to the application zone defined by the coloring devices 2 in the slightly prestressed state. Here the coloring process takes place. Subsequently, the take-off wheel 8 takes over the dyed wick strand 1 and transfers it to a conveyor belt 9 for further processing of the wick strand 1. The take-off wheel 8 is conveniently designed to run freely and has its own drive. This makes it possible the transport speed at which the take-off wheel 8 supplies the wick strand 1 to the conveyor belt 9 to set slightly higher or equal to the transport speed of the transport wheel 3. To guide the Wick strand 1 conveniently have both the feed wheel 4 and the transport wheel 3 and the take-off 8 at its periphery channel-shaped recesses, as in the FIGS. 2 and 3 for the feed wheel 4 and the transport wheel 3 are shown. The channel is thereby formed by the guideways 6 and 6 'and by the side guide webs 5 and 5'. The directions of rotation of the three wheels are in Fig. 1 illustrated by the corresponding arrows.

Um die über die Laufgeschwindigkeiten des Einzugsrades 4 und des Transportrades 3 vorgegebene Vorspannung an verschiedene Dicken und Festigkeiten des Dochtstranges 1 anpassen zu können, ist bevorzugt vorgesehen, dass die Drehgeschwindigkeiten dieser beiden Räder möglichst fein reguliert und aufeinander abgestimmt werden können. Für diese Geschwindigkeitsfeinregulierung gibt es sowohl mechanische als elektronische Lösungen.To be able to adapt to the predetermined speeds of the feed wheel 4 and the transport wheel 3 bias to different thicknesses and strengths of the wick strand 1, it is preferably provided that the rotational speeds of these two wheels as finely regulated and can be matched. There are both mechanical and electronic solutions for this fine-tuning of the speed.

Bei einer mechanischen Lösungsvariante ist vorgesehen, dass das Einzugsrad 4 mit dem Transportrad 3, vorzugsweise schlupffrei, zwangsgekoppelt ist. Hierzu kann eine nicht dargestellte aber einfach technisch realisierbare Anpressvorrichtung vorgesehen sein, welche das Transportrad 3 und das Einzugsrad 4 an ihren jeweiligen Umfangsflächen 10, 10' - hier mit den jeweiligen Seitenstegen 5, 5' - aneinander presst. In diesem schlupffreien Fall ergibt sich eine geringere Transportgeschwindigkeit des Einzugsrades 4 gegenüber der Transportgeschwindigkeit des Transportrades 3 und damit der gewünschte Verzögerungseffekt, wenn das Produkt des Radius r1 der Umfangsfläche 10' des Einzugsrades 4 mit dem Radius r3 der Führungsbahn des Transportrades 2 größer ist als das Produkt des Radius r2 der Führungsbahn 6' des Einzugsrades 4 mit dem Radius r4 der Umfangsfläche 10 des Transportrades 3. Verwendet man nun ein Einzugsrad 4, welches, insbesondere im Bereich der Seitenführungsstege 5', elastisch verformbares Material - wie zum Beispiel Gummi - aufweist, so lässt sich durch unterschiedlich starkes Anpressen des Einzugsrades 4 an das Transportrad 3 der Radius r1 vergrößern und verringern. Hierdurch wird automatisch das Verhältnis der Transportgeschwindigkeiten von Einzugsrad 4 und Transportrad 3 verändert. Dies ist eine einfache aber sehr gut funktionierende Form der Feinregulierung der Transportgeschwindigkeiten und damit der auf den Dochtstrang 1 aufgebrachten Zugspannung.In a mechanical solution variant is provided that the feed wheel 4 with the transport wheel 3, preferably slip-free, is positively coupled. For this purpose, a not shown but simply technically feasible pressing device may be provided, which presses the transport wheel 3 and the feed wheel 4 at their respective peripheral surfaces 10, 10 '- here with the respective side bars 5, 5' - to each other. In this slip-free case results in a lower transport speed of the feed wheel 4 with respect to the transport speed of the transport wheel 3 and thus the desired delay effect when the product of the radius r1 of the peripheral surface 10 'of the feed wheel 4 with the radius r3 of the guide rail of the transport wheel 2 is greater than that Product of the radius r2 of the guide track 6 'of the feed wheel 4 with the radius r4 of the circumferential surface 10 of the transport wheel 3. If now a feed wheel 4 is used, which, in particular in the area of the side guide webs 5', has elastically deformable material, such as rubber. so can increase and decrease by varying degrees of pressing the feed wheel 4 to the transport wheel 3, the radius r1. As a result, the ratio of the transport speeds of the feed wheel 4 and the transport wheel 3 is changed automatically. This is a simple but very well functioning form the fine regulation of the transport speeds and thus the tension applied to the wick strand 1.

Alternativ zu der geschilderten mechanischen Lösung kann die gewünschte Vorspannung auch durch eine, vorzugsweise elektronische, Regelung der Drehgeschwindigkeit eines nicht an das Transportrad 3 angepressten Einzugsrades 4 erfolgen. In diesem Fall sollte dann das Einzugsrad 4 einen eigenen Antrieb aufweisen, der in der gewünschten Weise eine Geschwindigkeitsfeinregulierung in Abhängigkeit der Drehgeschwindigkeit des Transportrades 3 ermöglicht. Darüber hinaus ist es natürlich auch möglich, verschiedenste Arten von an sich bekannten Getrieben zwischen Transportrad 3 und Einzugsrad 4 zu installieren, um den gewünschten Vorspannungseffekt zu erreichen.As an alternative to the described mechanical solution, the desired preload can also be effected by a preferably electronic control of the rotational speed of a feed wheel 4 which is not pressed against the transport wheel 3. In this case, then the feed wheel 4 should have its own drive, which allows in the desired manner a fine speed regulation as a function of the rotational speed of the transport wheel 3. In addition, it is of course also possible to install various types of transmissions known per se between the transport wheel 3 and feed wheel 4 in order to achieve the desired bias effect.

Fig. 2 zeigt die Übergabe des Dochtstranges 1 zwischen Einzugsrad 4 und Transportrad 3 im Bereich A der Fig. 1. Fig. 3 zeigt wie in der Applikationszone, also im Bereich der Färbungsvorrichtungen 2 mittels der Zugspannung eine satte Auflage des Dochtstranges 1 auf die Führungsbahn 6 des Transportrades 3 erreicht wird. Der Dochtstrang 1 füllt dabei den gesamten durch die Seitenführungsstege 5 und die Führungsbahn 6 begrenzten Kanal aus, wodurch eine besonders qualitativ hochwertige Applikation der Farbe möglich wird. Fig. 2 shows the transfer of the wick strand 1 between feed wheel 4 and transport wheel 3 in the area A of Fig. 1. Fig. 3 shows how in the application zone, ie in the field of coloring devices 2 by means of the tension a full circulation of the wick strand 1 on the guide track 6 of the transport wheel 3 is achieved. The wick strand 1 fills the entire limited by the side guide webs 5 and the guideway 6 channel, whereby a particularly high-quality application of the color is possible.

Gemäß dem zweiten Aspekt der Erfindung erfolgt im gezeigten Ausführungsbeispiel der Fig. 1 eine kontaktlose Applikation der Farbe. Hierfür sind in dieser Ausführungsvariante vier benachbarte Düsenpakete 2 zum Aufspritzen von Farbe auf den Dochtstrang 1 vorgesehen. Grundsätzlich würde auch ein Düsenpaket 2 ausreichen. In einer besonders bevorzugten Variante ist aber vorgesehen, verschiedene Farben, wie zum Beispiel rot und blau und gelb und schwarz, auf den Dochtstrang 1 aufzubringen, wofür im gezeigten Ausführungsbeispiel die vier Düsenpakete 2 für jeweils eine Farbe vorgesehen sind. Jedes dieser Düsenpakete 2 trägt - wie in Fig. 4 gezeigt - auf seiner zur Applikationszone gerichteten Seite eine Vielzahl von Düsen 7 zum Aufspritzen der Farbe. Bevorzugt ist dabei vorgesehen, dass die Düsen 7 zumindest teilweise einzeln und/oder in Gruppen ansteuerbar - insbesondere zu öffnen und zu schließen - sind. Um die besten Voraussetzungen für die Musteraufbringung zu gewährleisten, kann darüber hinaus der Abstand der Düsen 7 bzw. der Düsenpakete 2 zum Dochtstrang 1 bzw. zum Transportrad 3 einstellbar sein. Die Applikationsbreite kann an die Dochtstrangbreite durch Zu- oder Abschalten der randlich gelegenen Düsen 7 angepasst werden. Wie in Fig. 4 dargestellt, ist es darüber hinaus günstig, die Düsen 7 des Düsenpaketes 2, bezogen auf die Transportrichtung 11 des Dochtstranges 1, seitlich versetzt zueinander anzuordnen, damit bei vollständiger Öffnung aller Düsen 7 die Farbe in einer geschlossenen Fläche aufgebracht wird. Sämtliche Einstellmöglichkeiten der Düsenpakete 2 sind vorzugsweise programmierbar. Hierdurch wird es möglich, beliebige Muster in sehr hoher Qualität und mehrfarbig - zum Beispiel mit trichromatischem Effekt - auf den Dochtstrang 1 aufzubringen.According to the second aspect of the invention takes place in the illustrated embodiment of the Fig. 1 a contactless application of color. For this purpose, four adjacent nozzle packages 2 are provided for spraying paint on the wick strand 1 in this embodiment. In principle, a nozzle package 2 would be sufficient. In a particularly preferred variant, however, it is provided to apply different colors, such as red and blue and yellow and black, to the wick strand 1, for which, in the exemplary embodiment shown, the four nozzle packages 2 are provided for one color each. Each of these nozzle packages 2 carries - as in Fig. 4 shown on its side facing the application zone a plurality of nozzles 7 for spraying the paint. It is preferably provided that the nozzles 7 at least partially individually and / or controlled in groups - in particular to open and close - are. In addition, to ensure the best conditions for the pattern application, the distance between the nozzles 7 or the nozzle packages 2 to the wick strand 1 and the transport wheel 3 be adjustable. The application width can be adapted to the wick strand width by connecting or disconnecting the nozzles 7 located at the edge. As in Fig. 4 illustrated, it is also favorable, the nozzles 7 of the nozzle assembly 2, based on the transport direction 11 of the wick strand 1, laterally offset from each other to order so that upon complete opening of all nozzles 7, the color is applied in a closed area. All settings of the nozzle packages 2 are preferably programmable. This makes it possible to apply any pattern in very high quality and multi-color - for example, with trichromatic effect - on the wick strand 1.
