Abstract

Numerous supply vessels (V1 to Vn) containing basic dyes can be connected to mixing vessels (MB) via a distributor device (10). The basic dyes are metered via time-controlled valves (V1, V2, V3), the opening times of which are calculated according to the desired mixture ratio. A feedline (13) leads from each mixing vessel (MB) to a dispensing vessel (DB), from which the dye mixture is supplied to the consumer. The volume of the mixing vessel (MB) is not appreciably larger than that of the dispensing vessel (DB), and the preparation of a mixture batch is influenced by a filling-level detector (20) of the dispensing vessel (DB). Small and large textile surfaces can be selectively printed with the same pattern, without colour changes occurring. It is not necessary to provide appropriately large mixture quantities for large surfaces. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Farb­aufbereitung für die Färbung, insbesondere Farb­bemusterung, einer Textilbahn nach dem Oberbegriff des Patentanspruchs 1, insbesondere bei Bedruckungs­vorgängen.The invention relates to a device for color preparation for dyeing, in particular color sampling, a textile web according to the preamble of claim 1, especially in printing processes.

Es ist bekannt, auf Textilbahnen, z.B. auf Stoffe oder Teppichböden, Farbmuster durch Bedrucken aufzubringen. Jede Farbmischung wird der Verbraucherstelle aus einem Ausgabebehälter zugeführt, in dem die Farbmischung bereitgehalten wird. Das Auffüllen des Ausgabebehälters erfolgt aus einem die Farbmischung enthaltenden Reservoir heraus, in welches die betreffende Farb­mischung jeweils nachgefüllt wird. Ein Mischbehälter zur Herstellung der Farbmischung ist über eine Vertei­lervorrichtung an zahlreiche Vorratsbehälter für die Grundfarben anschließbar. Das Zuführen der Grundfarben zum Mischbehälter kann entweder durch gravimetrische Dosierung, also durch Wägen der zugeführten Grund­farbenmengen, erfolgen oder unter volumetrischer Steue­rung, d.h. durch Mengendosierung, beispielsweise mit Verdrängerpumpen. Üblicherweise haben die Mischbehälter ein Volumen, das etwa so groß ist wie dasjenige des Reservoirs, damit das Ansetzen der Farbmischungen in partiebezogenen großen Chargen erfolgen kann. Bei gravimetrischer Dosierung der Grundfarben ist die für das Ansetzen der Mischung benötigte Zeit relativ groß, weil das Abwiegen der Grundfarben nacheinander erfolgen muß und wegen des Einschwingverhaltens der Waage zeit­aufwendig ist. Volumetrische Mengendosierungen sind mit dem Nachteil einer relativ großen Ungenauigkeit be­haftet, so daß die Farbmischungen nicht mit der er­forderlichen Reproduzierbarkeit erzeugt werden.It is known to apply color samples to textile webs, for example to fabrics or carpets, by printing. Each color mixture is fed to the consumer point from an output container in which the color mixture is kept ready. The dispensing container is filled from a reservoir containing the color mixture, into which the respective color mixture is refilled. A mixing container for producing the color mixture can be connected to numerous storage containers for the primary colors via a distributor device. The feeding of the basic colors to the mixing tank can be done either by gravimetric dosing, that is, by weighing the supplied primary color quantities, or under volumetric control, ie by quantity dosing, for example with displacement pumps. The mixing containers usually have a volume that is approximately as large as that of the reservoir, so that the color mixtures can be prepared in batches that are batch-specific. With gravimetric dosing of the primary colors, the time required for preparing the mixture is relatively long because the primary colors have to be weighed one after the other and are time-consuming because of the settling behavior of the balance. Volumetric metering has the disadvantage of a relatively great inaccuracy, so that the color mixtures are not produced with the required reproducibility.

Die bekannten Vorrichtungen, bei denen aus Gründen der Gleichmäßigkeit der Farbmischungen großvolumige Misch­behälter erforderlich sind, haben den Nachteil, daß stets nur große Mengen von Textilbahn mit den gleichen Farbmischungen bedruckt werden können. Wenn das Muster und die hierzu benötigten Farbmischungen wechseln, müssen die Reservoirs entleert werden.The known devices, in which large-volume mixing containers are required for reasons of uniformity of the color mixtures, have the disadvantage that only large quantities of textile web can be printed with the same color mixtures. If the pattern and the required color mixtures change, the reservoirs must be emptied.

Kurzzeitige Änderungen des Farbmusters und der Farb­mischungen sind bei den bekannten Vorrichtungen nicht oder nur schwer möglich, weil dort Farbmischungen stets in sehr großer Menge angesetzt werden. Andererseits erlauben diese Vorrichtungen, falls mit ihnen große Textilbahnen bedruckt werden, nicht die Verwendung kleinvolumiger Mischbehälter, weil bei mehrmaligem Ansetzen der Farbmischungen die geforderte Farbkonstanz mit Sicherheit nicht gewährleistet wäre.Short-term changes in the color pattern and the color mixtures are not possible or are only possible with difficulty in the known devices, because color mixtures are always used in very large quantities. On the other hand, these devices, if they are used to print large textile webs, do not allow the use of small-volume mixing containers, because the required color consistency would not be guaranteed with repeated application of the color mixtures.

Der Erfindung liegt die Aufgabe zugrunde, eine Vor­richtung nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, die sowohl das Bemustern kleiner als auch das Bemustern großer Textilbahnen am Verbrauchsort mit hoher Konstanz der Farbmischungen ermöglicht und die somit eine hohe Flexibilität der Anwendung bietet, ohne Bevorratung großer Fertigfarbmischungen.The invention has for its object to provide a device according to the preamble of claim 1, which enables both the patterning of small and the patterning of large textile webs at the point of use with high consistency of the color mixtures and which thus offers a high degree of flexibility in use, without stocking large Ready-made color mixtures.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 an­gegebenen Merkmalen.This object is achieved according to the invention with the features specified in the characterizing part of patent claim 1.

Nach der Erfindung erfolgt das Ansetzen der Farb­mischungen in kleinen Chargen, so daß wahlweise sowohl kleine als auch große Textilbahnflächen mit demselben Flächenmuster, d.h. unter Verwendung derselben Farb­mischungen, bemustert werden können. Das Ansetzen einer Farbmischung erfolgt in dem Mischbehälter, der zugleich das Reservoir zum Nachfüllen des Ausgabebehälters bildet. Das Volumen dieses Mischbehälters braucht nicht wesentlich größer zu sein als dasjenige des Ausgabe­behälters. Die Steuerung der Füllung der Mischbehälter erfolgt in Abhängigkeit vom Füllstand, bzw. der noch vorhandenen Füllmenge, des jeweils zugehörigen Ausgabe­behälters. Das Ansetzen einer Mischung erfolgt nach der Erfindung auf Anforderung durch den Ausgabebehälter. Jeder Ausgabebehälter bildet zusammen mit dem zu­gehörigen Mischbehälter eine Art Tandemsystem, das in Zyklen betrieben wird. Immer dann, wenn der Füllstand des Ausgabebehälters ein bestimmtes Niveau erreicht hat, wird der Mischbehälter aufgefüllt, und wenn das Niveau des Ausgabebehälters noch weiter abgesunken ist, wird Farbmischung vom Mischbehälter in den Ausgabe­ behälter gefördert, wobei der Mischbehälter im wesent­lichen völlig entleert werden kann. Das Mischbehälter­volumen ist von einer solchen Größenordnung, daß es das im Ausgabebehälter erforderliche Puffervolumen an Farb­mischung bereitstellen kann. Es wird also nur soviel Farbmischung erzeugt, wie in den nächsten Minuten ver­braucht wird. Jedem Nachfüllzyklus des Ausgabebehälters entspricht ein Mischzyklus im Mischbehälter.According to the invention, the color mixtures are applied in small batches, so that both small and large textile web surfaces can be patterned with the same surface pattern, ie using the same color mixtures. Color mixing takes place in the mixing container, which at the same time forms the reservoir for refilling the dispensing container. The volume of this mixing container does not have to be significantly larger than that of the dispensing container. The filling of the mixing containers is controlled depending on the filling level, or the filling quantity still present, of the respectively associated dispensing container. According to the invention, a mixture is prepared on request by the dispensing container. Together with the associated mixing container, each dispensing container forms a type of tandem system that is operated in cycles. Whenever the filling level of the dispensing container has reached a certain level, the mixing container is refilled, and when the level of the dispensing container has dropped even further, color mixing from the mixing container into the dispenser conveyed container, the mixing container can be completely emptied substantially. The mixing container volume is of such an order of magnitude that it can provide the buffer volume of color mixture required in the dispensing container. So only as much color mixture is generated as will be used in the next few minutes. A mixing cycle in the mixing container corresponds to each refilling cycle of the dispensing container.

Mit den Merkmalen des Patentanspruchs 2 wird erreicht, daß die Farbmischungen bei den in kurzen Abständen aufeinanderfolgenden Chargen mit hoher Reproduzier­barkeit erzeugt werden. Während gravimetrische Dosier­verfahren zu langsam und volumentrische Dosierverfahren zu ungenau sind, erfolgt nach der Erfindung das Dosie­ren durch Zeitbemessung des Zustroms der Grundfarben in den Mischbehälter. Die Grundfarben werden in der Verteilervorrichtung unter Druck bereitgehalten, was dadurch erreicht werden kann, daß die Verteiler­vorrichtung an eine Druckquelle angeschlossen ist, oder daß jeder Vorratsbehälter ein Zirkulationssystem auf­weist, in dem die Farbe mit konstantem Pumpendruck um­gewälzt wird. Die Grundfarben können pastenförmige Kon­sistenz haben und werden beim Öffnen der Ventile, die in den zum Mischbehälter führenden Leitungen enthalten sind, durch konstanten Druck dosiert. Durch Bemessung der Öffnungszeiten der Ventile entsprechend dem ge­wünschten Mischungsverhältnis wird erreicht, daß die Grundfarben bei jedem Mischzyklus in genau demselben Mengenverhältnis zueinander in den Mischbehälter ein­gegeben werden.With the features of claim 2 it is achieved that the color mixtures are produced with high reproducibility in the batches which follow one another at short intervals. While gravimetric dosing processes are too slow and volumetric dosing processes are too imprecise, according to the invention the dosing is carried out by time measurement of the flow of the primary colors into the mixing container. The primary colors are kept under pressure in the distributor device, which can be achieved by connecting the distributor device to a pressure source or by providing each storage container with a circulation system in which the color is circulated with constant pump pressure. The basic colors can have a pasty consistency and are dosed by constant pressure when opening the valves contained in the lines leading to the mixing container. By dimensioning the opening times of the valves according to the desired mixing ratio, it is achieved that the basic colors are input into the mixing container in exactly the same proportion to each other during each mixing cycle.

Die zeitgesteuerte Dosierung ermöglicht die Bereit­stellung beliebig wählbarer Mengen an Farbmischung unter exakter Einhaltung des gleichen Mischungs­verhältnisses. Wenn die einzelnen Grundfarben unter­schiedliche Viskositäten haben, so wirken sich die Viskositätsunterschiede bei aufeinanderfolgenden Misch­zyklen jeweils in gleicher Weise aus, so daß das Mischungsverhältnis, selbst wenn es nicht exakt den eingestellten Werten entspricht, jedenfalls immer gleichbleibt.The time-controlled dosing enables the provision of any desired amount of color mixture with exact adherence to the same mixing ratio. If the individual primary colors have different viscosities, the viscosity differences have the same effect in successive mixing cycles, so that the mixing ratio always remains the same, even if it does not correspond exactly to the set values.

Im folgenden wird unter Bezugnahme auf die einzige Figur der Zeichnung ein Ausführungsbeispiel der Er­findung näher erläutert.In the following, an embodiment of the invention is explained in more detail with reference to the single figure of the drawing.

Die Zeichnung zeigt die schematische Darstellung einer Farbbereitstellungsvorrichtung zum Spritzbedrucken.The drawing shows the schematic representation of an ink supply device for spray printing.

Die zum Ansetzen der Farbmischungen benötigten Grund­farben sind in zahlreichen Vorratsbehältern V1 bis Vn enthalten. Sämtlichen Vorratsbehältern wird ein pneu­matischer Druck P zugeführt, um die Farben aus den Vor­ratsbehältern zu treiben. Alle Vorratsbehälter sind zu diesem Zweck an eine gemeinsame Druckluftquelle, deren Druck vorzugsweise auf einen konstanten Wert geregelt ist, angeschlossen.The basic colors required for preparing the color mixtures are contained in numerous storage containers V1 to Vn. Pneumatic pressure P is applied to all storage containers in order to drive the colors out of the storage containers. For this purpose, all storage containers are connected to a common compressed air source, the pressure of which is preferably regulated to a constant value.

Die Vorratsbehälter V1 bis Vn sind an eine Verteiler­vorrichtung 10 angeschlossen, die so ausgebildet ist, daß jeder Vorratsbehälter an jede von mehreren Misch­leitungen ML1, ML2, ML3 angeschlossen werden kann, die sämtlich zu jedem Mischbehälter MB führen. Obwohl die Vorrichtung zahlreiche Mischbehälter enthält, ist aus Gründen der Übersichtlichkeit nur einer dieser Misch­behälter MB mit den zugehörigen Mischleitungen ML1, ML2, ML3 dargestellt. Jede der Mischleitungen enthält ein Ventil V1, V2, V3. Diese Ventile sind von einem Zeitsteuerwerk 11 entsprechend dem gewünschten Mischungsverhältnis gesteuert. In jedem Mischzyklus, der beispielsweise eine Minute dauert, wird jedes der Ventile für eine Zeitspanne geöffnet, die der Mischungskomponente der durch das Ventil zugeführten Grundfarbe entspricht.The storage containers V1 to Vn are connected to a distributor device 10, which is designed such that each storage container can be connected to each of a plurality of mixing lines ML1, ML2, ML3, all of which lead to each mixing container MB. Although the device contains numerous mixing containers, only one of these mixing containers MB with the associated mixing lines ML1, ML2, ML3 is shown for reasons of clarity. Each of the mixing lines contains a valve V1, V2, V3. These valves are controlled by a time control unit 11 in accordance with the desired mixing ratio. In each mixing cycle, which lasts for example one minute, each of the valves is opened for a period of time which corresponds to the mixing component of the basic color supplied by the valve.

Der Mischbehälter MB ist zur Atmosphäre offen, und er enthält ein Rührwerk 12, das von einem (nicht dar­gestellten) Antrieb angetrieben ist. Vom Boden des Mischbehälters MB führt die Speiseleitung 13, die eine Zahnradpumpe 14 enthält, in den Ausgabebehälter DB. Die Zahnradpumpe 14 fördert die Farbmischung in den Aus­gabebehälter DB, der als geschlossener Druckbehälter ausgebildet und an eine Druckluftquelle angeschlossen ist. Vom Boden des Ausgabebehälters DB führt eine flexible Schlauchleitung 15 zu dem Düsenkopf 16, der über der Textilbahn 17 in Querrichtung zu dieser ver­schiebbar angeordnet ist. Der Düsenkopf 16 enthält zahlreiche auf die Textilbahn gerichtete Düsen 18, von denen jeder über die zugehörige Schlauchleitung 15 mit einem Ausgabebehälter DB verbunden ist. Die Düsen 18 sind als Ventile ausgebildet, die von einer Program­miereinrichtung impulsweise geöffnet werden können, um einen Punkt der zugehörigen Farbmischung auf die Textilbahn 17 zu spritzen. Die Steuerung der Düsen 18 durch die Programmiereinrichtung erfolgt in Abhängig­keit von der jeweiligen Position des Düsenkopfes 16 in Querrichtung der Textilbahn 17. Die Textilbahn 17 wird in Längsrichtung bewegt, so daß eine zeilenweise Spritzbedruckung in Form eines Punktrasters erfolgt.The mixing tank MB is open to the atmosphere and contains an agitator 12 which is driven by a drive (not shown). From the bottom of the mixing container MB, the feed line 13, which contains a gear pump 14, leads into the output container DB. The gear pump 14 conveys the color mixture into the output container DB, which is designed as a closed pressure container and is connected to a compressed air source. A flexible hose line 15 leads from the bottom of the dispensing container DB to the nozzle head 16, which is arranged so as to be displaceable in the transverse direction above the textile web 17. The nozzle head 16 contains numerous nozzles 18 directed towards the textile web, each of which is connected to an output container DB via the associated hose line 15. The nozzles 18 are designed as valves which can be opened in pulses by a programming device in order to spray a point of the associated color mixture onto the textile web 17. The control of the nozzles 18 by the programming device takes place as a function of the respective position of the nozzle head 16 in the transverse direction of the textile web 17. The textile web 17 is moved in the longitudinal direction, so that line-by-line spray printing takes place in the form of a dot pattern.

Am Ausgabebehälter DB sind mehrere Füllstandsdetektoren 19,20,21 in unterschiedlichen Höhen angebracht. Der untere Füllstandsdetektor 19 bewirkt, daß die Pumpe 14 eingeschaltet wird, um den Inhalt des Mischbehälters MB in den Ausgabebehälter DB zu fördern, wenn der Inhalt des Ausgabebehälters DB auf ein unteres Niveau ab­gesunken ist. Der Füllstandsdetektor 20 gibt, wenn der Füllstand auf den entsprechenden Pegel abgesunken ist, ein Signal an das Steuerwerk 11 zum Ansetzen einer neuen Mischung im Mischbehälter MB. Der obere Füll­standsdetektor 21 liefert ein Signal, das anzeigt, daß der Ausgabebehälter DB mit Farbmischung voll ist.Several fill level detectors 19, 20, 21 are attached to the dispensing container DB at different heights. The lower level detector 19 causes the pump 14 to be turned on to convey the contents of the mixing container MB into the dispensing container DB when the contents of the dispensing container DB have dropped to a lower level. The fill level detector 20, when the fill level has dropped to the corresponding level, gives a signal to the control unit 11 for preparing a new mixture in the mixing container MB. The upper level detector 21 provides a signal which indicates that the output container DB is full of color mixing.

Jedesmal wenn der Füllstand auf das Niveau des Füll­standsdetektors 20 absinkt, werden Grundfarben in dem eingestellten Mischungsverhältnis in den Mischbehälter MB eingeleitet. Der Mischbehälter weist einen Füll­standsdetektor 22 als Überlaufsicherung auf. Das Füll­ende des Mischbehälters wird durch die Zulaufdauer der am längsten zuzuführenden Mischungskomponente bestimmt. Das Volumen des Mischbehälters MB ist kleiner als das­jenige des Ausgabebehälters DB und entspricht dem Flüs­sigkeitsvolumen zwischen den Füllstandsdetektoren 19 und 21. Das Verhältnis der Volumina von Mischbehälter und Ausgabebehälter sollte im Bereich von 1:10 bis 1:0,8 liegen und vorzugsweise 1:1 betragen. Es muß sichergestellt sein, daß das Ansetzen der Farbmischung im Mischbehälter beendet ist, bevor das Niveau im Aus­gabebehälter DB auf das Niveau des Füllstandsdetektors 19 abgesunken ist und die Pumpe 14 zu fördern beginnt, damit die Mischung von dem Mischwerk 12 vollständig durchgerührt ist, bevor sie den Mischbehälter verläßt. Der Füll- und Mischzyklus des Mischbehälters ist daher kürzer als die kürzeste Entleerungsdauer des Ausgabe­ behälters DB zwischen den Füllstandsdetektoren 20 und 19.Every time the level drops to the level of the level detector 20, primary colors are introduced into the mixing container MB in the set mixing ratio. The mixing container has a fill level detector 22 as an overflow protection. The filling end of the mixing container is determined by the duration of the addition of the mixture component to be supplied longest. The volume of the mixing container MB is smaller than that of the dispensing container DB and corresponds to the liquid volume between the fill level detectors 19 and 21. The ratio of the volumes of the mixing container and dispensing container should be in the range from 1:10 to 1: 0.8 and preferably 1: 1 be. It must be ensured that the preparation of the color mixture in the mixing container has ended before the level in the output container DB has dropped to the level of the fill level detector 19 and the pump 14 has started to be conveyed so that the mixture is completely stirred by the mixer 12 before it leaves the mixing container. The filling and mixing cycle of the mixing container is therefore shorter than the shortest emptying time for the dispenser container DB between the level detectors 20 and 19.

Mit der beschriebenen Vorrichtung können Textilbahnen aller Art bedruckt werden, also auch beispielsweise Teppichböden. Der Begriff Textilbahn schließt auch be­grenzte Bahnelemente, wie beispielsweise Teppichfliesen ein. Die Farbaufbereitungsvorrichtung, die hier für den Spritzdruck beschrieben wurde, kann auch für andere Arten der Farbbemusterung mit Farbgemischen benutzt werden, beispielsweise für Schablonendruck, oder für die Kontinuefärbung.With the device described, textile webs of all kinds can be printed, including carpets, for example. The term textile web also includes limited web elements, such as carpet tiles. The ink preparation device that has been described here for spray printing can also be used for other types of color sampling with color mixtures, for example for stencil printing, or for continuous dyeing.
