Abstract

A yarn to be dyed at intermittent locations is continuously transported at high speed and in stretched condition past a nozzle supplied with dyestuff under pressure, with interposition of one or more rotary shutters such as disks with arrays of apertures of various configurations centered on the axis of rotation. Synchronization between yarn motion and shutter rotation may be achieved by designing the shutter as a grooved pulley or sheave with a frustoconical recess having apertures near the groove bottom through which a yarn entraining the pulley or entrained by it can be sprayed by a nozzle lodged in the recess.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum abschnittweise unterschiedlichen Färben von Garnen, mit mindestens einer über eine Farbflottenzuleitung gespeisten Farbspritzdüse, an der Garn mit hoher Laufgeschwindigkeit in gestrecktem Zustand vorbeizuführen und dabei mit Farbflotte intermittierend zu bespritzen ist, wobei zwischen der Farbspritzdüse und dem daran vorbeilaufenden Garn ein mit Durchtrittsöffnungen versehenes, umlaufendes Zerteilerorgan vorbeiläuft, das den aus der Düse austretenden Farbflottenstrahl zerteilt.The invention relates to a device for dyeing yarns differently in sections, with at least one paint spray nozzle fed via a paint liquor feed line, to pass the yarn in a stretched state at high running speed and to be sprayed intermittently with paint liquor, whereby between the paint spray nozzle and the one running past it Yarn passes a circumferential dividing member provided with through openings, which divides the liquor jet emerging from the nozzle.

Bei durch die DE-A1460349 und die CH-PS 459 bekannten Vorrichtungen obiger Art, die zum farbigen Bemustern weniger von Textilgarn als vielmehr von Textilbahnen, wie Stoffen ud. dgl. dienen, besteht das zwischen der Farbspritzdüse und dem zu färbenden Textilgut vorbeilaufende Zerteilerorgan aus einem mit entsprechend der gewünschten Bemusterung perforierten, endlos umlaufenden Schablonenband oder einer Schablonentrommel, die jeweils um senkrecht zum Farbflottenstrahl verlaufende Achsen verlaufen. Da das Schablonenband oder die -trommel dabei um die gesamte Farbspritzvorrichtung, nämlich um die Farbspritzdüsen, deren Farbflotten- und Blasmediumszuleitungen herumgeführt werden, besitzen sie eine entsprechend große Länge bzw. Größe und damit auch eine entsprechend große Massenträgheit, die nur geringe Umlaufgeschwindigkeiten zuläßt. Dadurch wird aber nicht nur die Produktionsleistung beeinträchtigt, sondern auch der Farbspritzstrahl nur unzureichend zerteilt, so daß die bekannten Vorrichtungen für das Färben von Garnen mit verhältnismäßig kurzen unterschiedlich gefärbten Abschnitten ungeeignet sind.In the devices of the above type known from DE-A1460349 and CH-PS 459, which are less of textile yarn than textile webs, such as fabrics, for colored sampling. Like. Serve, the separating element passing between the paint spray nozzle and the textile material to be dyed consists of an endlessly circulating stencil tape or a stencil drum perforated with the desired pattern, each of which runs around axes perpendicular to the dye liquor jet. Since the stencil ribbon or the drum around the entire paint spraying device, namely around the paint spray nozzles, the paint liquor and blowing medium supply lines are guided around, they have a correspondingly large length or size and thus a correspondingly large mass inertia, which only allows low circulation speeds. This not only affects the production output, but also the paint spray jet is insufficiently divided, so that the known devices for dyeing yarns with relatively short differently colored sections are unsuitable.

Demgegenüber können mit einer durch die DE-OS 25 54 132 bekannten Vorrichtung Garne oder Zwirne mit sogenannter « space »- oder « Multicolor •-Färbung mit großer Produktionsleistung und verhältnismäßig sparsamem Farbflottenverbrauch hergestellt werden, wobei das intermittierende Bespritzen des an der Farbspritzdüse vorbeilaufenden Garns dadurch erfolgt, daß in die Farbflottenzuleitung der Spritzdüse ein Doppel-Ventil mit zwei unmittelbar hintereinander angeordneten Einzetventilen eingebaut ist, die zur Erzeugung kurzzeitiger Farbspritzimpulse gleichzeitig, aber mit gegenseitig einstellbarer Phasenverschiebung zu öffnen und zu schließen sind. Dadurch gelingt es, äußerst kurzzeitige Farbspritzimpulse zu erzeugen, wie sie für die sogenannte « mini-space •-Färbung von Garnen wünschenswert und notwendig sind, insbesondere für den Fall, daß das zu färbende Garn dabei mit hoher, normaler Umspulgeschwindigkeit entsprechender Laufgeschwindigkeit an der Farbspritzdüse bzw. mehreren solcher Düsen vorbeigeführt wird. Das erfordert aber einen verhältnismäßig großen Ventil-, Schaltungs- und Steuerungsaufwand.In contrast, with a device known from DE-OS 25 54 132, yarns or threads with so-called "space" or "multicolor" dyeing can be produced with high production output and relatively economical consumption of paint liquor, the intermittent spraying of the yarn passing the paint spray nozzle thereby is carried out that a double valve is installed in the paint liquor feed line of the spray nozzle with two single valves arranged immediately one behind the other, which can be opened and closed simultaneously to generate short-term paint spray pulses, but with mutually adjustable phase shift. This makes it possible to generate extremely short-term paint spray pulses, as are desirable and necessary for the so-called "mini-space" dyeing of yarns, in particular in the event that the yarn to be dyed at the paint spray nozzle at a high, normal rewinding speed or several such nozzles is passed. But that requires a relatively large valve, circuit and control effort.

Weiterhin ist es zum abschnittweise unterschiedlichen Färben von Garnen durch die DE-OS 23 20 215 bekannt, die Garne in gestrecktem Zustand an Farbspritzdüsen vorbeizuführen, die gegenüber dem Garniauf eine Changier-Bewegung vollführen. Da diese mit nur begrenzter Geschwindigkeit erfolgt und die Öffnungszeiten der Farbspritzdüsen nicht beliebig kurz gehalten werden können, lassen sich damit aber selbst bei verhältnismäßig langsamer Garnlaufgeschwindigkeit nur relativ lange Garnabschnitte unterschiedlich färben, und das auch nur mit vergleichsweise beschränkter Durchsatzleistung.Furthermore, it is known from DE-OS 23 20 215 for the different dyeing of yarns in sections, to guide the yarns in the stretched state past paint spraying nozzles which perform a traversing movement relative to the yarns. Since this takes place at only a limited speed and the opening times of the paint spray nozzles cannot be kept as short as desired, only relatively long yarn sections can be dyed differently even with a relatively slow yarn running speed, and this only with a comparatively limited throughput.

Schließlich ist es beim Färben von Garnen auch bekannt (ITB Färberei/Druckerei/Ausrüstung 3/1975, S. 237), die Farbflotte in kontinuierlichem Strahl auf eine schnell rotierende Scheibe zu spritzen, von der sie unter Einwirkung der Zentrifugalkraft in Form kleiner Tröpfchen auf das an der Scheibe vorbeilaufende Garn aufgespritzt wird. Damit sind aber regelmäßige bzw. reproduzierbare Garnfärbungen nicht zu erhalten. Auch ist der Farbflottenverbrauch dabei unverhältnismäßig hoch.Finally, when dyeing yarns, it is also known (ITB dyeing / printing / equipment 3/1975, p. 237) to spray the dye liquor in a continuous stream onto a rapidly rotating disc, from which it forms small droplets under the action of centrifugal force the yarn running past the disc is sprayed on. However, regular or reproducible yarn dyeings cannot be obtained with this. The color liquor consumption is also disproportionately high.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum abschnittweise unterschiedlichen Färben von Garnen zu schaffen, die von verhältnismäßig einfacher und störunanfälliger Bauart ist sowie große Durchsatzleistungen und selbst dabei noch sehr kurze unterschiedlich gefärbte Garnabschnitte bei sparsamem Flottenverbrauch zu erzielen erlaubt. Diese Aufgabe wird ausgehend von einer Vorrichtung der eingangs erwähnten Gattung erfindungsgemäß dadurch gelöst, daß das umlaufende Zerteilerorgan aus einer scheibenförmigen Rotorblende besteht. Da die umlaufende Rotorblende verhältnismäßig massearm und ihre Masse noch dazu nahe um ihre Antriebswelle herum angeordnet ist, kann sie mit hoher Drehzahl angetrieben werden. Auch die Fadenlaufgeschwindigkeit kann dadurch entsprechend gesteigert werden, so daß damit insgesamt sehr kurze Farbspritzimpulse einfach dadurch erzielt werden können, daß der aus der Düse austretende Farbflottenstrahl entsprechend kurzzeitig zerhackt wird, bevor er auf das hinter der Rotorblende vorbeilaufende Garn gelangt. Dazu werden weder verschmutzungsanfällige Ventile noch größere umlaufende oder hin- und her zu bewegende Massen benötigt. Die von der Rotorblende zurückgehaltenen Farbflottenteile können durch entsprechend hohe Zentrifugalwirkung abgeschleudert und leicht entfernt, z. B. abgesaugt werden, so daß jeweils reproduzierbare Farbspritzbedingungen aufrechterhalten werden können.The invention is therefore based on the object to provide a device for sectionally different dyeing of yarns, which is of relatively simple and failure-prone design and allows high throughputs and even very short differently colored yarn sections to be achieved with economical fleet consumption. Starting from a device of the type mentioned at the outset, this object is achieved according to the invention in that the circumferential dividing member consists of a disk-shaped rotor aperture. Since the rotating rotor orifice is relatively low in mass and its mass is arranged close to its drive shaft, it can be driven at high speed. The thread speed can also be increased accordingly, so that overall very short paint spray pulses can be achieved simply by chopping the paint liquor jet emerging from the nozzle for a short time before it reaches the yarn passing behind the rotor screen. Neither valves susceptible to contamination nor larger circulating or reciprocating masses are required for this. The liquor parts retained by the rotor orifice can be thrown off by a correspondingly high centrifugal effect and easily removed, e.g. B. be sucked off so that reproducible paint spray conditions can be maintained.

Die Rotorblende kann aus einer Flügelscheibe oder aus einer Lochscheibe mit einem aus Rund-und/oder Schlitzlöchern bestehenden, den Farbflottenstrahl zerteilenden Lochkranz bestehen.The rotor diaphragm can consist of a wing disk or of a perforated disk with a perforated ring consisting of round and / or slotted holes and dividing the dye liquor jet.

Noch vorteilhafter ist es für die Praxis, wenn bei einer Vorrichtung der eingangs erwähnten Gattung die Rotorblende erfindungsgemäß aus einem auf einer Welle fliegend gelagerten Lochrad besteht, das an seinem Umfang eine umlaufende Garnführungsnut, an seiner der Welle abgewandten und der Farbspritzdüse zugewandten Seite eine die Düse teilweise umgreifende trichterförmige Aussparung sowie in der Aussparungswandung einen Lochkranz aufweist, dessen Rund- und/oder Schlitzlöcher in den Garnführungsnutboden ausmünden. Auch in diesem Falle kann das vorbeilaufende Garn, wenn auch nicht frei laufend sondern am Garnführungsnutboden vorübergehend anliegend und das Lochrad antreibend, mit kurzzeitigen, durch die Löcher des Lochkranzes hindurchtretenden Farbspritzimpulsen intermittierend beaufschlagt werden, wobei das mit hoher Drehzahl umlaufende Lochrad für seine selbsttätige Reinigung von überschüssiger Farbflotte durch dessen Abschleuderung sorgt.It is even more advantageous in practice if According to the invention, a device of the type mentioned at the outset comprises a perforated wheel which is mounted on a shaft and has a circumferential yarn guide groove on its circumference, a funnel-shaped recess partially encompassing the nozzle on its side facing away from the shaft and facing the paint spray nozzle, and a perforated ring in the recess wall has, the round and / or slot holes open into the yarn guide groove bottom. In this case, too, the passing yarn, if not running freely but temporarily against the bottom of the yarn guide and driving the pinwheel, can be intermittently acted upon by short-term paint spray pulses passing through the holes in the ring of holes, whereby the pinwheel rotating at high speed for its automatic cleaning of excess paint liquor ensures by spinning.

Nach einem weiteren Merkmal der Erfindung können vorteilhaft auch zwei oder mehrere koaxial unmittelbar hintereinanderliegende, mit verschiedenen Drehzahlen zu betreibende und mit Loch- oder Flügelkränzen versehene Rotorblenden vorgesehen sein. Durch das Zusammenwirken ihrer unmittelbar hinter- bzw. übereinander liegenden Loch- oder Flügelkränze und deren unterschiedliche Loch- oder Flügelunterteilung können auf diese Weise gewollt unregelmäßig aufeinander folgende kurzzeitige Farbstoffaufträge auf das Garn erzielt werden, wodurch die andernfalls bei daraus zu konfektionierenden Waren auftretenden Bilderungseffekte vermieden werden können. Insbesondere empfiehlt sich hierfür eine Doppel-Rotorblenden-Anordnung, bei der in der trichterförmigen Aussparung des Lochrades eine entsprechend trichterförmig gestaltete Flügelscheibe angeordnet ist, deren Antriebswelle die hohl ausgebildete Antriebswelle des Lochrades zentral durchsetzt.According to a further feature of the invention, it is also advantageously possible to provide two or more rotor diaphragms which are located directly one behind the other and can be operated at different speeds and are provided with perforated or winged rings. Through the interaction of their perforated or winged rings lying directly behind or on top of each other and their different perforation or wing subdivision, short successive short-term dye applications can be achieved on the yarn in this way, thereby avoiding the formation effects that would otherwise occur in the goods to be assembled therefrom can. In particular, a double rotor orifice arrangement is recommended for this purpose, in which a correspondingly funnel-shaped wing disk is arranged in the funnel-shaped recess of the perforated wheel, the drive shaft of which centrally penetrates the hollow drive shaft of the perforated wheel.

In allen Fällen ist es zweckmäßig, die Antriebswellen der Zerteilerorgane mit dem das Garn fördernden Garnlieferwerk antriebsmäßig synchron zu verbinden. Dadurch wird sichergestellt, daß sich über längere Garnabschnitte das gleiche Garneinfärbungsmuster regelmäßig wiederholt, letzteres also weder zunehmend gedehnt noch verkürzt wird.In all cases, it is expedient to connect the drive shafts of the dividing members in synchronism with the yarn supplying unit that conveys the yarn. This ensures that the same yarn coloring pattern is repeated regularly over longer sections of yarn, so that the latter is neither increasingly stretched nor shortened.

Die einzeln oder auch paarweise vorhandenen Zerteilerorgane sind vorteilhaft in einer die Farbspritzdüse enthaltenden Spritzkammer untergebracht, die mit einer oder mehreren Leitungsanschlüssen zum Ableiten und/oder Absaugen von überschüssiger Farbflotte bzw. Farbflottennebel versehen ist. Dabei ist das Spritzkammergehäuse vorteilhaft mit mehreren bis nahe an den Umfang des Zerteilerorgans heranreichenden Saugkanälen versehen, die in eine gemeinsame ringförmige Farbflottensammelkammer ausmünden. Hierdurch ist es möglich, bei vorgegebener Gesamtabsaugeleistung an den umlaufenden Abschleuderkanten des Zerteilerorgans eine verhältnismäßig starke Saugwirkung zu erzielen, die das Abschleudern und Entfernen überschüssiger Farbflotte wirksam unterstützt.The separator elements, which are present individually or in pairs, are advantageously accommodated in a spray chamber containing the paint spray nozzle, which is provided with one or more line connections for draining and / or suctioning off excess paint liquor or paint liquor mist. In this case, the spray chamber housing is advantageously provided with a plurality of suction channels which extend close to the circumference of the dividing member and which open out into a common annular paint fleet collecting chamber. This makes it possible to achieve a relatively strong suction effect on the circumferential centrifugal edges of the dividing member for a given total suction power, which effectively supports the centrifuging and removal of excess paint liquor.

Um Garne mit « Multicolor ».Effekt, also verschiedenartig eingefärbte Garne herstellen zu können, kann man mehrere mit Zerteilerorganen versehene, vom Garn nacheinander zu durchlaufende Spritzkammern hintereinander anordnen, deren Spritzdüsen dann jeweils mit der entsprechend beschaffenen Farbflotte gespeist werden. Die zu den einzelnen Spritzkammern und deren Düsen führenden Farbflottenzuleitungen zweigen vorteilhaft jeweils von einer in sich geschlossenen Farbflottenversorgungsleitung ab, in der sich eine die Farbflotte unter Druck setzende Umwälzpumpe und hinter dem Farbflottenzuleitungsabzweig ein Druckreduzierventil sowie dahinter ein mit einem Füllstandsschalter ausgerüsteter Farbflotten-Mischbehälter befinden, in den sowohl die von den Spritzkammern kommende Absaugleitung für überschüssige bzw. verbleibende Farbflotte als auch eine von einem Farbflotten-Vorratsbehälter kommende Frischflottenleitung einmünden, in der sich ein vom Füllstandsschalter gesteuertes Absperrventil befindet. Zweckmäßig ist dabei noch in die von den Spritzkammern kommende Absaugleitung für verbleibende Flotte ein mit einem Entlüftungskamin und darin eingebautem Sauggebläse versehener Flottenabscheider eingebaut. Auf diese Weise läßt sich ein geringstmöglicher Farbflottenverbrauch erzielen, .wobei die jeweils verbrauchte Farbflottenmenge durch entsprechende Nachlieferung von frischer Farbflotte ersetzt wird und damit auch eine gleichbleibende Farbflottenbeschaffenheit aufrechterhalten werden kann.In order to be able to produce yarns with a "multicolor" effect, i.e. differently colored yarns, one can arrange several spray chambers with splitter elements, which the yarn has to pass through in succession, the spray nozzles of which are then fed with the appropriately procured paint liquor. The paint liquor supply lines leading to the individual spray chambers and their nozzles advantageously branch off from a self-contained paint liquor supply line in which there is a circulating pump that pressurizes the paint liquor and behind the paint liquor supply branch a pressure reducing valve and behind it a paint liquor mixing container equipped with a level switch which both the suction line coming from the spraying chambers for excess or remaining paint liquor and a fresh liquor line coming from a paint liquor storage container, in which a shut-off valve controlled by the fill level switch is located. A fleet separator provided with a ventilation chimney and suction fan installed therein is also expediently installed in the suction line for remaining liquor coming from the spray chambers. In this way, the lowest possible use of color liquor can be achieved, whereby the amount of color liquor used in each case is replaced by a corresponding subsequent delivery of fresh color liquor, and thus a constant color liquor quality can be maintained.

Die in den Fig. 1 und 2 dargestellte Garnfärbevorrichtung besteht im wesentlichen aus der Farbspritzkammer 1, der darin befindlichen, an der Gehäusewand 2 befestigten Farbspritzdüse 3 und der zwischen letzterer und dem daran vorbeilaufenden Garn 4 vorhandenen, umlaufend anzutreibenden Rotorblende 5, die hier als einfache Lochscheibe 5 ausgebildet ist und durch den angeflanschten Elektromotor 6 über dessen Welle 7 mit regelbarer Drehzahl anzutreiben ist. Die Lochscheibe ist im vorliegenden Falle mit in regelmäßigen Abständen angeordneten Löchern 5' versehen, die einen gemeinsamen Lochkranz bilden, der bei der schnellen Umlaufbewegung der Lochscheibe 5 den aus der Spritzdüse 3 austretenden Farbstoffstrahl 8 entsprechend zerhackt bzw. unterteilt, so daß auf das hinter dem Lochkranz der Lochscheibe 5 mit hoher Geschwindigkeit von beispielsweise 600 bis 1 200 m/Min vorbeilaufende Garn 4 lediglich äußerst kurze Farbspritzimpulse gelangen, die auf dem Garn einen entsprechenden « space-dying »-Effekt ergeben. Die Spritzdüse 3 ist mit einem über die Stromzuleitung 9 gesteuerten elektromagnetischen Absperrventil versehen, das die über die Zuleitung 10 unter entsprechendem Überdruck herangeführte Farbflotte für den Austritt an der Düse 3 freigibt oder aber davon abzusperren erlaubt. Im Spritzkammergehäuse 2 sind mehrere Saugleitungsanschlüsse 11, 12, 13 und 14 vorhanden, von denen erstere überwiegend zum Absaugen bzw. Ableiten überschüssiger Farbflotte dienen, wohingegen die Saugleitungsanschlüsse 13, 14 vornehmlich zum Entfernen des feineren Farbstoffnebels bestimmt sind. Durch die mit Hilfe eines Schiebers 15 mehr oder weniger abzudeckenden Belüftungsöffnungen 16 kann entsprechende Frischluft in die Spritzkammer 1 nachgesaugt werden. Dadurch wird hier insgesamt eine übermäßige Anhäufung von Farbstoffflotte oder -nebel verhindert. Die Saugleitungsanschlüsse 12, 13 und 14 befinden sich vorteilhaft in der durch die umlaufende Lochscheibe 5 verlaufenden Ebene, um die von der Lochscheibe 5 abgeschleuderten Farbstoffreste 17 schnell abfangen und ableiten zu können.The yarn dyeing device shown in FIGS. 1 and 2 consists essentially of the paint spraying chamber 1, the paint spray nozzle 3 located therein, which is attached to the housing wall 2, and the rotor screen 5 which is to be driven and circulates between the latter and the yarn 4 running past it, which here is simple Perforated disc 5 is formed and by the flanged electric motor 6 over it Drive shaft 7 with adjustable speed. The perforated disk is provided in the present case with holes 5 'arranged at regular intervals, which form a common ring of holes which correspondingly chopped or divided the dye jet 8 emerging from the spray nozzle 3 during the rapid orbital movement of the perforated disk 5, so that on the behind Perforated ring of perforated disc 5 at a high speed of, for example, 600 to 1,200 m / min passing yarn 4 only extremely short paint spray pulses arrive, which result in a corresponding "space-dying" effect on the yarn. The spray nozzle 3 is provided with an electromagnetic shut-off valve controlled via the power supply line 9, which releases the paint liquor supplied via the supply line 10 under a corresponding excess pressure for the outlet at the nozzle 3 or allows it to be shut off. In the spray chamber housing 2 there are a plurality of suction line connections 11, 12, 13 and 14, of which the former are mainly used for suctioning or discharging excess paint liquor, whereas the suction line connections 13, 14 are primarily intended for removing the finer dye mist. Corresponding fresh air can be drawn into the spray chamber 1 through the ventilation openings 16, which are more or less covered with the aid of a slide 15. This prevents an excessive build-up of dye liquor or mist. The suction line connections 12, 13 and 14 are advantageously located in the plane running through the peripheral perforated disk 5, in order to be able to quickly intercept and discharge the dye residues 17 thrown off by the perforated disk 5.

Die in den Fig. 3. und 4 dargestellte Garnfärbevorrichtung unterscheidet sich von der vorbeschriebenen im wesentlichen dadurch, daß hier zwei koaxial unmittelbar hintereinanderliegende Lochscheiben 18, 19 vorhanden sind. Sie sind über ihre Antriebswellen 18' bzw. 19' und die darauf sitzenden Antriebsräder 18" bzw. 19" von unterschiedlich großem Durchmesser über die Antriebsriemen 20 bzw. 21 mit den verschieden großen Antriebsrädern 22, 23 auf der Welle 24 eines Garnlieferrades 25 antriebsmäßig verbunden, so daß die beiden Lochscheiben 18, 19 mit verschiedenen Drehzahlen, aber synchron zur Drehzahl des vom Garn 4 umschlungenen Lieferrades 25 umlaufen. Die Lochscheiben 18, 19 sind, wie insbesondere Fig. 3 zeigt, mit deckungsgleich übereinander liegenden Lochkränzen versehen, die jeweils aus unterschiedlich angeordneten und ausgebildeten Rundlöchern 26 sowie Schlitzlöchern 27 bzw. 27' bestehen. Durch das Zusammenwirken der beiden Lochscheiben 18, 19 bzw. ihrer Lochkränze können hier aus dem aus der Spritzdüse 3 kontinuierlich austretenden Farbflottenstrahl unterschiedlich kurze Farbspritzimpulse erzeugt werden, die auf das hinter dem Lochkranz der Scheibe 18 vorbeilaufende Garn gelangen und auf diesem entsprechend unterschiedlich kurze Einfärbungen hervorrufen. Die hier vorhandene synchrone Umlaufbewegung der Lochscheiben 18, 19 gegenüber der Garnlieferrolle 25 und damit auch zur Garnlaufgeschwindigkeit ist u. a. auch deswegen von Vorteil, weil dadurch beim An- und Auslaufen der Lochscheiben bzw. Ein- und Ausschalten des Garnlieferwerks keine Einfärbungsfehler auftreten, die andernfalls zu erheblichem Garnausschuß führen würden.The yarn dyeing device shown in FIGS. 3 and 4 differs from the one described above essentially in that there are two perforated disks 18, 19 lying coaxially one behind the other. They are connected via their drive shafts 18 'or 19' and the drive wheels 18 "or 19" of different sizes with the drive belts 20 or 21 to the drive wheels 22, 23 of different sizes on the shaft 24 of a yarn delivery wheel 25 , so that the two perforated disks 18, 19 rotate at different speeds, but synchronously with the speed of the delivery wheel 25 wrapped in yarn 4. The perforated disks 18, 19 are, as shown in particular in FIG. 3, provided with congruent perforated rings, which each consist of differently arranged and designed round holes 26 and slotted holes 27 and 27 '. Due to the interaction of the two perforated disks 18, 19 or their perforated rings, differently short paint spraying pulses can be generated from the paint liquor jet continuously emerging from the spray nozzle 3, which get onto the yarn passing behind the perforated ring of the disk 18 and cause correspondingly short dyeings thereon . The existing synchronous orbital movement of the perforated disks 18, 19 relative to the yarn delivery roll 25 and thus also to the yarn running speed is u. a. This is also an advantage because when the perforated disks start and stop or the yarn supply unit is switched on and off, there are no coloring errors which would otherwise lead to considerable yarn rejection.

Bei der in den Fig. 5 und 6 dargestellten Garnfärbevorrichtung besteht das umlaufende Zerteilerorgan aus einem auf einer Lagerwelle 28 fliegend gelagerten Lochrad 29, das an seinem Umfang eine umlaufende, V-förmige Garnführungsnut 30, an seiner der Lagerwelle 28 abgewandten und der hier entsprechend schräggestellten Farbspritzdüse 3 zugewandten Seite eine die Düse 3 teilweise umgreifende, trichterförmige Aussparung 31 sowie in der Aussparungswandung 31' einen Lochkranz aufweist, dessen Rund- und/oder Schlitzlöcher 32 in den Boden 30' der Garnführungsnut 30 ausmünden. Das über ein nicht dargestelltes Lieferwerk geförderte Garn 4, das unter entsprechender Umlenkung am Nutboden 30' teilweise anliegt und dadurch das Lochrad 29 mit der Garnlaufgeschwindigkeit entsprechender Drehzahl antreibt bzw. mitnimmt, wird auch hier durch den vom umlaufenden Lochrad 29 zerhackten Farbflottenstrahl 8 mit entsprechend kurzzeitigen Farbspritzimpulsen beaufschlagt und dadurch abschnittweise eingefärbt. Die überschüssige Farbflotte läuft infolge Schleuderwirkung an den V-förmig verlaufenden Nutwandungsflächen nach außen und wird davon schließlich abgeschleudert. Um die überschüssige Farbflotte möglichst wirkungsvoll und schnell aus der Spritzkammer 1 zu entfernen, ist hier das Spritzkammergehäuse 2 mit mehreren, bis nahe an den Umfang des Lochrades 29 heranreichenden Saugkanälen 33 versehen, die in eine gemeinsame ringförmige Farbflottensammelkammer 34 ausmünden, von der die sich hier ansammelnde Farbflotte über den Ableitungsanschluß 35 abgesaugt werden kann.In the yarn dyeing device shown in FIGS. 5 and 6, the circumferential dividing member consists of a perforated wheel 29, which is overhung on a bearing shaft 28 and which has a circumferential, V-shaped yarn guide groove 30 on its circumference, on its side facing away from the bearing shaft 28 and which is accordingly inclined here Paint spray nozzle 3 facing side has a funnel-shaped recess 31 which partially surrounds the nozzle 3 and has a perforated ring in the recess wall 31 ', the round and / or slotted holes 32 of which open into the bottom 30' of the yarn guide groove 30. The yarn 4, which is conveyed via a delivery mechanism (not shown), which partially rests against the groove base 30 'with a corresponding deflection and thereby drives or takes the perforated wheel 29 at the corresponding speed with the yarn running speed, is also here briefly by the liquor jet 8 chopped by the rotating perforated wheel 29 Paint spray pulses applied and thereby colored in sections. The excess liquor runs to the outside due to the centrifugal effect on the V-shaped groove wall surfaces and is finally thrown off. In order to remove the excess paint liquor from the spray chamber 1 as effectively and quickly as possible, here the spray chamber housing 2 is provided with a plurality of suction channels 33 which come close to the periphery of the perforated wheel 29 and which open into a common annular paint fleet collection chamber 34, of which the here accumulating paint liquor can be sucked off through the drain port 35.

Um vor Beginn des Farbspritzens das Garn 4 in die Spritzkammer 1 bequem einführen und in die Umfangsnut 30 am Lochrad 29 einlegen zu können, ist das Spritzkammergehäuse 2, wie Fig.5 zeigt, vorteilhaft mit einem vom Spritzkammergehäuseboden 2' abnehmbaren bzw. dagegen begrenzt ausziehbaren Gehäusedeckel 2" versehen. Im übrigen versteht es sich, daß hier wie auch in allen anderen Fällen die das Zerteilerorgan tragende Antriebs- oder Lagerwelle in entsprechenden Wälzlagern 36 gelagert ist, um eine entsprechende Leichtgängigkeit der Rotorblende zu gewährleisten.In order to be able to conveniently insert the yarn 4 into the spray chamber 1 and to insert it into the circumferential groove 30 on the perforated wheel 29 before the paint spraying begins, the spray chamber housing 2, as shown in FIG. 5, is advantageously provided with a removable or limited pull-out from the spray chamber housing base 2 ' Housing cover 2 "provided. Furthermore, it goes without saying that here, as in all other cases, the drive shaft or bearing shaft carrying the dividing member is mounted in corresponding roller bearings 36 in order to ensure that the rotor diaphragm runs smoothly.

Bei der in den Fig. 7 und 8 dargestellten Ausführungsform ist gleichfalls ein umlaufendes Lochrad 29 vorhanden, wobei jedoch in dessen trichterförmiger Aussparung 31 hier noch zusätzlich eine entsprechend trichterförmig gestaltete Flügelscheibe 37 angeordnet ist, deren Antriebswelle 38 die hohl ausgebildete Antriebswelle 39 des Lochrades 29 zentral durchsetzt. Wie Fig. 7 zeigt, ist die Flügelscheibe 37 vorzugsweise mit ungleichmäßig über ihren Umfang verteilt angeordneten Flügeln 37' versehen, die im Zusammenwirken mit den Rund- und Schlitzlöchern 32 bzw. 32' des Lochrades 29 den aus der auch hier entsprechend schräg gestellten Farbspritzdüse 3 austretenden Farbflottenstrahl 8 entsprechend unregelmäßig zerhacken bzw. zerteilen, so daß das im Boden der Garnführungsnut 30 anliegende bzw. hier vorbeilaufende Garn über abwechselnd verschieden lange bzw. kurze Garnabschnitte eingefärbt wird. Wie aus Fig. ersichtlich, können hier wie auch bei den übrigen Zerteilerorganen durchaus auch zwei oder mehrere Garne parallel laufend gleichzeitig abschnittweise eingefärbt werden. Der Antrieb des Laufrades 29 und seiner Welle 39 erfolgt hier über einen Keilriemen 40 durch einen Motor 41 mit regelbarer Drehzahl, der zugleich auch das Garnlieferwerk antreibt, wohingegen das Flügelrad 37 mit seiner Welle 38 durch den Motor 42 mit gleichfalls regelbarer Drehzahl angetrieben wird. Durch die synchrone Antriebskupplung zwischen dem Lochrad 29 und dem Garnlieferwerk wird jedweder Schlupf zwischen dem Garn 4 und dem Lochrad 29 vermieden, der andernfalls zu entsprechenden Farbverwischungen auf dem Garn 4 führen könnte.In the embodiment shown in FIGS. 7 and 8 there is also a rotating perforated wheel 29, but in the funnel-shaped recess 31 there is also an appropriately funnel-shaped wing disk 37, the drive of which shaft 38 passes through the hollow drive shaft 39 of the perforated wheel 29 centrally. As shown in FIG. 7, the wing disk 37 is preferably provided with wings 37 ′ which are distributed unevenly over its circumference and which, in cooperation with the round and slot holes 32 and 32 'of the perforated wheel 29, from the paint spray nozzle 3, which is also inclined accordingly here Chopping or dividing emerging ink liquor jet 8 accordingly, so that the yarn lying in the bottom of the yarn guide groove 30 or passing by is dyed over alternately different lengths or short yarn sections. As can be seen in FIG. 2, two or more yarns can also be dyed in parallel at the same time in sections, as is the case with the other dividing members. The impeller 29 and its shaft 39 are driven here via a V-belt 40 by a motor 41 with a variable speed, which at the same time also drives the yarn delivery unit, whereas the impeller 37 with its shaft 38 is driven by the motor 42 with a likewise variable speed. The synchronous drive coupling between the perforated wheel 29 and the yarn delivery mechanism avoids any slippage between the yarn 4 and the perforated wheel 29 which could otherwise lead to corresponding color blurring on the yarn 4.

Die vorbeschriebenen Garnfärbevorrichtungen ermöglichen durchweg die Herstellung von « u-ni "-gefärbtem Garn mit verschieden kurzen Einfärbungsabschnitten. Will man dagegen « multicolor •-Garn herstellen, so werden dazu jeweils mehrere, mit den vorbeschriebenen Zerteilerorganen versehene und mit der entsprechenden Farbflotte zu speisende Spritzkammern 1 hintereinander geschaltet, die von dem einzufärbenden Garn 4 nacheinander durchlaufen werden. Auch kann auf diese Weise beispielsweise durch Hintereinander-Anordnung zweier Spritzkammern gemäß der Fig.5 und 6, zwirnimitiertes Garn hergestellt werden, wobei dann aber die beiden Lochräder 29 der beiden Spritzkammern synchron angetrieben werden müssen, so daß dann jeweils in regelmäßigen Abständen auf dem Garn die die Zwirnimitierung ergebende unterschiedliche Einfärbung auftritt.The above-described yarn dyeing devices enable the production of "u-ni " -dyed yarn with differently short dyeing sections. If, on the other hand, one wants to produce "multicolor • yarn, several spray chambers are provided with the above-mentioned dividing organs and to be fed with the corresponding dye liquor 1 connected in series, through which the yarn 4 to be dyed passes one after the other. Also in this way, for example by arranging two spray chambers one behind the other according to FIGS must be driven, so that the threading imitation resulting in different colors then occurs at regular intervals on the yarn.

Ein auch für die Hintereinander-Anordnung mehrerer mit Zerteilerorganen ausgerüsteter Spritzkammern geignetes Farbflotten-Versorgungssystem ist in Fig. 9 dargestellt. Hiernach sind die zu den Spritzkammern bzw. deren Farbspritzdüsen 3 führenden Farbflottenzuleitungen 10, von denen im vorliegenden Falle nur eine dargestellt ist, an eine in sich geschlossene Farbflottenversorgungsleitung 43 angeschlossen, in der sich eine die Farbflotte unter Druck von ca. 1 bis 2,5 atü stellende Umwälzpumpe 44, ein Filter 45, ein Manometer 46, ein hinter den Abzweigstellen 10' der Farbzuleitungen 10 vorhandenes Druckreduzierventil 47 und ein Farbflotten-Mischbehälter 48 befinden. In diesem Mischbehälter 48 mündet eine Zuleitung 49 für zurückfließende bzw. verbleibende Farbflotte ein, die von dem Flottenabscheider 50 abzweigt, der seinerseits über die Saugleitung 51 mit der jeweiligen Spritzkammer verbunden ist, also daraus die überschüssige verbleibende Farbflotte erhält. Der Flottenabscheider 50 ist mit einem Entlüftungskamin 50' und einem darin eingebauten Sauggebläse versehen, das die von der verbleibenden Farbflotte im Abscheider 50 abgetrennte Luft über das Aufsatzrohr 52 daraus entfernt. Somit sammelt sich die über die Leitung 51 zuströmende verbliebene Farbflotte im unteren Teil des Flottenabscheiders 50 an, von wo aus sie über die Leitung 49 in den Mischbehälter 48 gelangt. Dieser steht weiterhin über die Zuleitung 53 und das Absperrventil 54 mit einem Farbflotten-Vorratsbehälter in Verbindung. Das Ventil 54 wird durch einen im Mischgefäß 48 untergebrachten Füllstandsschalter 55, beispielsweise einen Schwimmerschalter, entsprechend gesteuert. Auf diese Weise kann die in den Spritzkammern jeweils verbrauchte Farbflotte durch Öffnen des Schwimmergesteuerten Ventils 54 durch die Nachlieferung frischer Farbflotte aus dem nicht dargestellten Vorratsbehälter ersetzt werden, wodurch zugleich auch eine gleichbleibende Farbflottenbeschaffenheit erzielt wird. Es versteht sich, daß das vorbeschriebene Farbflotten-Versorgungssystem nur für eine bestimmte Farbflotte benutzbar ist, so daß also für eine etwaige Multicolor-Färbung des Garns für jede der aufzutragenden Farben und die daran beteiligten Spritzkammern ein eigenes Farbflotten-Versorgungssystem vorhanden ist.A paint liquor supply system which is also suitable for arranging a plurality of spray chambers equipped with dividing members one behind the other is shown in FIG. 9. According to this, the paint liquor supply lines 10 leading to the spray chambers or their paint spray nozzles 3, of which only one is shown in the present case, are connected to a self-contained paint liquor supply line 43 in which the paint liquor is under pressure of approx. 1 to 2.5 circulating pump 44, a filter 45, a manometer 46, a pressure reducing valve 47 present behind the branch points 10 'of the paint feed lines 10 and a paint liquor mixing container 48. A feed line 49 for the flowing back or remaining paint liquor opens into this mixing container 48, which branches off from the liquor separator 50, which in turn is connected to the respective spray chamber via the suction line 51, that is to say it receives the excess remaining paint liquor therefrom. The liquor separator 50 is provided with a ventilation chimney 50 ′ and a suction blower installed therein, which removes the air separated from the remaining paint liquor in the separator 50 via the attachment pipe 52. The remaining paint liquor flowing in via the line 51 thus collects in the lower part of the liquor separator 50, from where it reaches the mixing container 48 via the line 49. This is also connected via the feed line 53 and the shut-off valve 54 to a liquor of dye liquor. The valve 54 is controlled accordingly by a fill level switch 55, for example a float switch, accommodated in the mixing vessel 48. In this way, the paint liquor used in each of the spraying chambers can be replaced by opening the float-controlled valve 54 by supplying fresh paint liquor from the storage container (not shown), which also results in a constant paint liquor quality. It is understood that the above-described paint liquor supply system can only be used for a specific paint liquor, so that a separate paint liquor supply system is available for any multicolor dyeing of the yarn for each of the colors to be applied and the spray chambers involved.
