Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ausrüstung, insbesondere der chemischen Ausrüstung, einer Warenbahn.The invention relates to a method and a device for equipment, in particular the chemical equipment, a web.
Unter "Warenbahn" sollen im vorliegenden Fall Flächengebilde verstanden werden, die Fasern oder Fäden umfassen, wie beispielsweise Papier, Textil oder Vlies umfassende Flächengebilde.In the present case, "web" is to be understood as meaning webs comprising fibers or threads, such as, for example, paper, textile or nonwoven fabrics.
Chemische Ausrüstungsverfahren sind beispielsweise: Färben, Drucken, flammhemmende, bleichende, waschmaschinenfeste Ausrüstung, Nanoausrüstung, Fleckenschutzausrüstung, UV-Blocker-Ausrüstung, Antistatik-Ausrüstung, antibakterielle Ausrüstung, Bügelfrei-Ausrüstung, Ausbrenner-Ausrüstung, Repellent-Ausrüstung oder Insektizid-Ausrüstung. Die Ausrüstung einer Warenbahn umfasst u.a. den Auftrag der im Allgemeinen flüssigen Chemikalie, der sogenannten Flotte, auf die Warenbahn. Die Menge dieser Chemikalie, die am Ende des Ausrüstungsprozesses tatsächlich auf der Warenbahn, insbesondere auf den Fasern oder Fäden nach dem Trocknen vorhanden sein muss, um die gewünschte Funktonalität des Produkts zu gewährleisten, wird als Fadenauflage bezeichnet.Chemical finishing processes include, for example: dyeing, printing, flame retardant, bleaching, machine-washable equipment, nano-equipment, stain-resistant equipment, UV blocking equipment, antistatic equipment, antibacterial equipment, iron-free equipment, burn-out equipment, repellent equipment, or insecticide equipment. The equipment of a web includes u.a. the order of the generally liquid chemical, the so-called fleet, on the web. The amount of this chemical which, at the end of the finishing process, must actually be present on the web, in particular on the fibers or filaments after drying, in order to ensure the desired functionality of the product, is referred to as a thread rest.
Es ist bekannt, zum Flottenauftrag Auftragswerke einzusetzen, bei denen mittels einer Antragswalze Flotte aus einem Flottenreservoir auf die Warenbahn aufgetragen wird. Hierzu kann die Antragswalze in einem die Flotte enthaltenden Flottenbecken rotieren, wobei die Walzenoberfläche durch die Flotte benetzt wird. Die Flotte wird auf die Warenbahn, die an der Walzenoberfläche außerhalb des Flottenbeckens entlang befördert wird, durch Kontaktberührung übertragen.It is known to use commissions for liquor order, in which by means of a request roller fleet from a fleet reservoir is applied to the web. For this purpose, the application roller in a liquor basin containing the fleet rotate, wherein the roll surface is wetted by the liquor. The liquor is transferred to the web, which is conveyed along the roll surface outside the liquor basin, by contact contact.
Die Menge an Flotte, die pro Volumeneinheit auf die Warenbahn aufgetragen wird, wird auch kurz mit "Flottenauftrag" bezeichnet.The amount of liquor applied to the web per unit volume is also referred to as "fleet order" for short.
Der Flottenauftrag hängt von einer Vielzahl von Parametern ab, beispielsweise von der Viskosität der Flotte, von dem Umschlingungswinkel, über den die Warenbahn an der Antragswalze anliegt, von der Vorlaufgeschwindigkeit der Warenbahn und von der Rotationsgeschwindigkeit der Antragswalze.Fleet application depends on a large number of parameters, for example on the viscosity of the liquor, on the wrap angle over which the fabric web is applied to the applicator roll, on the advance speed of the fabric web and on the rotational speed of the applicator roll.
Um eine über die Länge der Warenbahn konstante Funktionalität der Warenbahn zu erhalten, muss die Fadenauflage möglichst konstant gehalten werden. Hierzu ist es nicht ausreichend, den Flottenauftrag konstant zu halten, da die Fadenauflage auch bei konstant gehaltenem Flottenauftrag variieren kann, beispielsweise bei Änderung der Konzentration der Ausrüstungschemikalie in der Flotte, Änderung des Ausrüstungsverhaltens der Ausrüstungschemikalie und/oder der Warenbahn bei Prozesstemperaturschwankungen etc.In order to obtain a constant over the length of the web functionality of the web, the thread support must be kept as constant as possible. For this purpose, it is not sufficient to keep the fleet order constant, since the thread support can vary even with constantly maintained fleet order, for example, when changing the concentration of the chemical equipment in the fleet, change the equipment behavior of the equipment chemical and / or the web in process temperature fluctuations, etc.
Zur Konstanthaltung der Eigenschaften der Warenbahn werden daher sämtliche Parameter in Abhängigkeit der auszurüstenden Warenqualität aufeinander, meist empirisch, abgestimmt und während des Prozesses möglichst konstant gehalten. Eine Überwachung der Eigenschaften der Warenbahn ist nur durch Stichproben und zumeist nur in zeitaufwendigen Analyseverfahren im Labor möglich. Da die Ergebnisse der Analysen nur zeitversetzt vorliegen, kommt es zu in jeder Hinsicht nachteiligen Unterbrechungen des Verfahrens sowie zur Produktion von Ausschuss in nicht unerheblichem Ausmaß. Eine lückenlose Qualitätssicherung ist mit den bekannten Verfahren gar nicht zu erreichen.To keep constant the properties of the web, therefore, all parameters depending on the quality of goods to be matched, usually empirically, coordinated and kept as constant as possible during the process. A monitoring of the properties of the web is possible only by random sampling and usually only in time-consuming analysis methods in the laboratory. Since the results of the analyzes are only delayed, adverse disruption of the process in every respect and production of rejects occur to a not inconsiderable extent. A complete quality assurance can not be achieved with the known methods.

Der Erfindung liegt daher die Aufgabe zugrunde, ein die obigen Nachteile vermeidendes und damit verbessertes Verfahren zur Ausrüstung einer Warenbahn sowie eine zugehörige Vorrichtung bereitzustellen.The invention is therefore based on the object to provide a the above disadvantages avoiding and thus improved method for equipping a web and an associated device.
Diese Aufgabe wird durch das in Anspruch 1 wiedergegebene Verfahren sowie die Vorrichtung zur Anwendung des Verfahrens nach Anspruch 6 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by the reproduced in claim 1 method and the apparatus for applying the method according to
Bei dem erfindungsgemäßen Verfahren zur Ausrüstung einer Warenbahn wird die Warenbahn an einer rotierenden, mit einer Flotte benetzten Auftragswalze vorbeitransportiert, um die Flotte auf die Warenbahn aufzutragen und um so eine Ausrüstung der textilen Warenbahn zu erreichen. Ausrüstungsverfahren im Sinne der Erfindung sind beispielsweise: Färben, Drucken, flammhemmende, bleichende, waschmaschinenfeste Ausrüstung, Nanoausrüstung, Fleckenschutzausrüstung, UV-Blocker-Ausrüstung, Antistatik-Ausrüstung, antibakterielle Ausrüstung, Bügelfrei-Ausrüstung, Ausbrenner-Ausrüstung, Repellent-Ausrüstung oder Insektizid-Ausrüstung. Bei der Warenbahn kann es sich um ein beliebiges, Fasern oder Fäden aufweisendes Flächengebilde handeln, beispielsweise um Papier, Textil oder Vlies.In the method according to the invention for finishing a material web, the web is conveyed past a rotating application roller wetted with a liquor in order to apply the liquor to the web and thus to achieve finishing of the textile web. Finishing methods according to the invention are, for example: dyeing, printing, flame-retardant, bleaching, machine-washable equipment, nano-equipment, stain-proofing equipment, UV blocking equipment, antistatic equipment, antibacterial equipment, ironless equipment, burnout equipment, repellent equipment or insecticidal equipment. Equipment. The web may be any fabric having fibers or threads, for example paper, textile or nonwoven.
Erfindungsgemäß wird an der weitertransportierten Warenbahn nach dem Trocknen die Fadenauflage fortlaufend gemessen und nachfolgend beispielsweise durch eine Auswerteinheit, ausgewertet. In Abhängigkeit des Messergebnisses, beispielsweise durch Vergleich mit einem empirisch bestimmten Sollwert, wird gegebenenfalls und beispielsweise mittels einer Steuereinheit die Rotationsgeschwindigkeit der Walze geregelt.According to the invention, the thread support is continuously measured on the further transported fabric after drying and subsequently evaluated, for example, by an evaluation unit. Depending on the measurement result, for example by comparison with an empirically determined desired value, the rotational speed of the roller is optionally controlled, for example, by means of a control unit.
Bisher wurde die Ansicht vertreten, dass eine Konstanthaltung der Fadenauflage nur dann zu gewährleisten ist, wenn sämtliche die Fadenauflage beeinflussenden Parameter strengstens überwacht und auf konstantem Niveau gehalten werden. Es bestand ferner bisher die Ansicht, dass insbesondere beim Minimalauftrag Abweichungen in einem der Parameter nicht und schon gar nicht fortlaufend während des Ausrüstvorgangs durch Variation eines anderen Parameters zu kompensieren ist.So far, the view has been taken that a constant maintenance of the thread support is only to be ensured if all the thread support influencing parameters are strictly monitored and maintained at a constant level. Furthermore, it has previously been the opinion that deviations in one of the parameters should not be compensated, and certainly not continuously during the finishing process, by variation of another parameter, in particular in the case of minimal application.
Ein dieser Ansicht zuwiderlaufender Grundgedanke der Erfindung besteht daher darin, eine Variation der Rotationsgeschwindigkeit der auftragenden Walze zur Kompensation von Abweichungen anderer Parameter, wie Flottenkonzentration, - Viskosität, Warenbahngeschwindigkeit und Umschlingungswinkel, die zu Änderungen der Fadenauflage führen, zu verwenden. In mehreren Versuchen hat sich überraschend gezeigt, dass eine Regulierung der Rotationsgeschwindigkeit der auftragenden Walze nicht nur aufgrund des großen Regulierbereichs Abweichungen der Fadenauflage von einem Sollwert und insbesondere beim Minimalauftrag zu kompensieren vermag. Eine Anpassung und genaue Überwachung der anderen Parameter, die zumeist mit Unterbrechungen des Auftragsverfahrens verbunden sind, können so vorteilhaft entfallen.A basic idea of the invention, contrary to this view, is therefore to use a variation of the rotational speed of the applying roller to compensate for deviations of other parameters, such as liquor concentration, viscosity, web speed and wrap angle, which lead to changes in the thread support. In several attempts has been surprising shown that a regulation of the rotational speed of the applying roller not only due to the large Regulierbereichs can compensate for deviations of the thread support from a target value and in particular the minimum order. An adaptation and close monitoring of the other parameters, which are usually associated with interruptions of the order process, can be advantageously eliminated.
Eine weitere, wesentliche Idee der Erfindung ist es, die Messung und eine damit gegebenenfalls verbundene Anpassung des betroffenen Parameters fortlaufend durchzuführen. Dadurch können Ausschussmengen, die Mengen an Waren 2. Wahl und allgemein die Produktionskosten gesenkt werden, da die Abweichung bei kontinuierlicher Durchführung des Verfahrens in einem kleinen, zeitlichen Toleranzfenster gehalten werden kann.Another essential idea of the invention is to continuously carry out the measurement and, if appropriate, associated adaptation of the relevant parameter. This can reduce rejects, the amount of second-choice goods and, more generally, the production costs, since the deviation can be kept within a small tolerance window when the process is carried out continuously.
Es hat sich ferner überraschend gezeigt, dass eine Anpassung mittels der Rotationsgeschwindigkeit der Antragswalze sich auch besonders eignet, da die Rotationsgeschwindigkeit besonders einfach und vor Allem mit hoher Regelgeschwindigkeit und - genauigkeit einzustellen ist, ohne den Herstellungsprozess unterbrechen zu müssen.It has also surprisingly been found that an adaptation by means of the rotational speed of the application roller is also particularly suitable since the rotational speed can be set particularly easily and above all with high control speed and accuracy without having to interrupt the production process.
In einer vorteilhaften Ausführungsform der Erfindung werden elektrische Eigenschaften der Warenbahn gemessen und ausgewertet, um eine zuverlässige Bestimmung der Fadenauflage zu erreichen.In an advantageous embodiment of the invention, electrical properties of the web are measured and evaluated in order to achieve a reliable determination of the thread support.
In einer weiteren vorteilhaften Ausführungsform umfasst der Sensor einen Plattenkondensator. Die Warenbahn durchläuft das Feld des Plattenkondensators beim Transport. Die Fadenauflage kann mittels eines Verfahrens gemessen werden, wie es für sich genommen bereits aus der
Ein derartiges Verfahren zeichnet sich durch die vergleichsweise schnelle Ermittlung der Änderung der Fadenauflage aus. Durch dieses Verfahren kann die Messung und Auswertung der Fadenauflage bzw. deren Änderung in besonders kleinen Zeitintervallen, nahezu kontinuierlich und besonders zeitnah durchgeführt werden. Ausschuss kann besonders verringert oder gar verhindert werden.Such a method is characterized by the comparatively rapid determination of the change of the thread support. By this method, the measurement and evaluation of the thread support or its change in particularly small time intervals, can be carried out almost continuously and especially promptly. Scrap can be particularly reduced or even prevented.
Bevorzugt wird bei einer Verringerung der Fadenauflage gegenüber einem Sollwert die Rotationsgeschwindigkeit der auftragenden Walze erhöht und bei einer Vergrößerung der Dicke der Fadenauflage gegenüber einem Sollwert die Rotationsgeschwindigkeit verringert. Der Sollwert kann beispielsweise empirisch für eine vorgegebene Textilqualität bestimmt sein.Preferably, when the thread support is reduced relative to a desired value, the rotational speed of the applying roller is increased and the rotational speed is reduced when the thickness of the thread support increases compared to a desired value. The desired value can be determined, for example, empirically for a given textile quality.
Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung der Verfahren gemäß einer der vorher beschriebenen Ausführungsformen. Diese umfasst eine Walzenanordnung, bei der eine Warenbahn an einer rotierenden, mit einer Flotte benetzten Antragswalze vorbeitransportiert wird, um die Flotte auf die Warenbahn aufzutragen. Die Vorrichtung zeichnet sich dadurch aus, dass in Transportrichtung der Warenbahn dem Auftrag nachfolgend ein Sensor angeordnet ist, um die Fadenauflage oder deren Änderung nach Trocknung der Warenbahn zu messen. Ferner ist eine Auswerte- und Steuereinheit vorgesehen, um in Abhängigkeit des Messergebnisses, beispielsweise durch Vergleich mit einem Sollwert, die Rotationsgeschwindigkeit der Antragswalze zu regeln, d.h. anzupassen. Wie schon zuvor ausgeführt, hat sich überraschend und in einer Vorurteile überwindenden Weise herausgestellt, dass durch die Messung der Fadenauflage in Abhängigkeit dieser Messung erfolgender und einer Regulierung der Rotationsgeschwindigkeit der Antragswalze nicht nur eine fortlaufende und damit eine Ausschuss verringernde Qualitätssicherung bewirkt werden kann, sondern auch andere Parameter weniger genau überwacht werden müssen oder deren Schwankungen ohne zusätzlichen Eingriff in das Verfahren kompensiert werden können.The invention further relates to an apparatus for carrying out the method according to one of the previously described embodiments. This comprises a roller arrangement in which a material web is transported past a rotating application roller wetted with a liquor in order to apply the liquor to the material web. The device is characterized in that in the transport direction of the web following the order, a sensor is arranged to measure the thread support or its change after drying of the web. Furthermore, an evaluation and control unit is provided in order to regulate the rotational speed of the application roller in dependence on the measurement result, for example by comparison with a desired value, i. adapt. As stated previously, surprisingly and in a prejudice-overcoming manner has been found that by measuring the thread support depending on this measurement successful and a regulation of the rotational speed of the applicator roll not only a continuous and thus a committee reducing quality assurance can be effected, but also other parameters need to be monitored less accurately or their fluctuations compensated without additional intervention in the process.
In einer Ausgestaltung umfasst der Sensor einen Plattenkondensator, wobei die Warenbahn durch das von dem Plattenkondensator erzeugte elektrische Feld transportiert wird. Dadurch kann die Messung vorteilhaft berührungslos erfolgen.In one embodiment, the sensor comprises a plate capacitor, wherein the web is transported by the electric field generated by the plate capacitor. As a result, the measurement can advantageously be carried out without contact.
Die Walzenanordnung umfasst vorzugsweise eine Antragswalze, mittels welcher Flotte aus einem Reservoir auf die Warenbahn aufgebracht wird. Hierzu kann die Antragswalze in einen Flottenbehälter teilweise eingetaucht sein.The roller arrangement preferably comprises an application roller, by means of which liquor from a reservoir is applied to the material web. For this purpose, the application roller may be partially immersed in a fleet container.
