Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Einstellung gleichmäßiger Behandlungsmittelaufträge auf laufenden Warenbahnen, insbesondere auf Gewebe- und Gewirkebahnen.The invention relates to a method and a device for setting uniform treatment agent orders on running webs, in particular on woven and knitted webs.

Die Erfindung geht von der durch Untersuchungen gewonnenen Erkenntnis aus, daß ein Zusammenhang zwischen der Durchströmbarkeit von Geweben, Gewirken oder dergl. für ein bestimmtes Luftvolumen und der Farbtiefe beim Farbflottenauftrag auf diese Gewebe oder Gewirke besteht, d.h. kurz unterschiedliche Durchströmbarkeiten führen auch zu unterschiedlichen Farbtiefen bei der Färbung dieser Gewebe oder Gewirke.The invention is based on the knowledge gained by investigations that there is a connection between the permeability of fabrics, knitted fabrics or the like for a certain air volume and the depth of color when dye liquor is applied to these fabrics or knitted fabrics, i.e. briefly different flow rates also lead to different color depths when dyeing these fabrics or knitted fabrics.

Es ist nun bekannt, die unterschiedlichen Farbtiefen in angefärbten Warenbahnen dadurch zu vergleichmäßigen, daß bei der nachgeschalteten Abquetschung mit Foulards die Quetschdrücke über die Warenbahnbreite unterschiedlich eingestellt werden. Bei einer bekannten Vorrichtung zur Einstellung des Liniendruckes bei Quetschwalzensystemen erfolgt dabei die Einstellung des Liniendruckes in Abhängigkeit von über die Breite der Warenbahn gemessener Feuchtegehalte der Warenbahn (DE-PS 26 46 897).It is now known to equalize the different color depths in the dyed webs in that the squeezing pressures across the web width are set differently in the subsequent squeezing with foulards. In a known device for setting the line pressure in the case of squeeze roller systems, the line pressure is set as a function of the moisture content of the web measured over the width of the web (DE-PS 26 46 897).

Die Schwierigkeiten bei dieser Vorrichtung liegen in der häufig nicht sicheren Ermittlung der die Regelung der Liniendrücke auslösenden Feuchtemeßwerte, weil diese Geräte berührungslos arbeiten müssen, da eine Anlage auf der gefärbten Warenbahn zu Markierungen führen würde. Außerdem sind diese Feuchtemeßgeräte aufwendig und teuer, so daß in der Regel nur ein Meßgerät verwendet wird, welches über die Warenbahnbreite verschoben wird und so nur aufeinanderfolgend Meßwerte über die Warenbahnbreite liefern kann.The difficulties with this device lie in the often unsafe determination of the moisture measurement values which trigger the regulation of the line pressures, because these devices have to work without contact, as a system on the colored web would lead to markings. In addition, these moisture measuring devices are complex and expensive, so that usually only one measuring device is used, which is shifted across the width of the web and can thus only provide successive measurements over the width of the web.

Durch die vorliegende Erfindung sollen diese Nachteile vermieden und die Aufgabe gelöst werden, mit einfachen Mitteln sichere Meßwerte für die Steuerung des Liniendruckes des nachgeschalteten Quetschwerkes über die Warenbahnbreite zu erhalten.These disadvantages are to be avoided by the present invention and the object is to be obtained with simple means reliable measured values for controlling the line pressure of the downstream squeezing mechanism over the width of the web.

Zur Lösung dieser Aufgabe wird dazu erfindungsgemäß ein Verfahren vorgeschlagen, bei dem die trockene Warenbahn vor dem Behandlungsmittelauftrag Durchströmungsmessungen über die Warenbahnbreite verteilt unterworfen wird und die sich dabei egebenden unterschiedlichen Durchströmungswerte zur Einstellung der unterschiedlichen Liniendrücke der Abquetschung des aufgetragenen Behandlungsmittels über die Warenbahnbreite verwendet werden.To achieve this object, a method is proposed according to the invention in which the dry web is subjected to flow measurements over the web width before the treatment agent is applied and the resulting different flow values are used to adjust the different line pressures to squeeze the applied treatment agent over the web width.

Bei einer Vorrichtung zur Durchführung dieses Verfahrens sollen Mittel zur Durchströmung der Warenbahn mit Sensoren für die Messung der Durchströmbarkeit der Warenbahnen verbunden sein.In a device for carrying out this method, means for flowing through the material web are to be connected to sensors for measuring the flow through the material web.

Dabei können die Mittel zur Durchströmung der Warenbahnen mit definiertem und einstellbarem Druck an die Warenbahnen anpreßbare Düsenköpfe zum Aufblasen eines konstanten und definierten Luftstromes auf die laufenden Warenbahnen sein. Zur Einstellung eines definierten Anpreßdruckes an die Warenbahnen sollen dabei mit den Düsenköpfen Gewichte auswechselbar verbunden sein. Als Sensoren sollen vorzugsweise Staudruckmesser verwendet werden.The means for flowing through the material webs with defined and adjustable pressure can be die heads which can be pressed onto the material webs to inflate a constant and defined air flow onto the running material webs. In order to set a defined contact pressure on the material webs, weights should be interchangeably connected to the nozzle heads. Dynamic pressure gauges should preferably be used as sensors.

Die Mittel zur Durchströmungsmessung der Warenbahen können auch als unterhalb der Warenbahnen angeordnete und an diesen anliegende Saugdüsenköpfe mit Drosselblenden und Geschwindigkeitsmessern ausgebildet sein.The means for measuring the flow through the goods webs can also be designed as suction nozzle heads with throttling orifices and speedometers arranged underneath the webs and resting on them.

Weiterhin können die Mittel zur Druchströmung der Warenbahnen als in an Traversen gehaltenen, über die größte Breite der Warenbahnen sich erstreckenden Führungskanälen frei verschiebbare Außenmeßköfpfe ausgebildet sein. Bei einer solchen Ausbildung der erfindungsgemäßen Vorrichtung werden Faltenbildungen in den Warenbahnen, die bei einzelnen getrennten Düsenköpfen gelegentlich auftreten können, sicher vermieden, außerdem ist damit eine leichte Anpassung an unterschiedliche Warenbahnbreiten erreichbar.Furthermore, the means for the through-flow of the material webs can be designed as external measuring heads which are freely displaceable in guide channels which are held on traverses and extend over the greatest width of the material webs. With such a configuration of the device according to the invention, wrinkles in the material webs, which can occasionally occur in the case of individual, separate nozzle heads, are reliably avoided, and moreover an easy adaptation to different web widths can be achieved.

Zweckmäßig können in den Führungskanälen oder/und an den Außenköpfen Gleitführungen für die Außenmeßköpfe vorgesehen werden. Zur einwandfreien Führung der Warenbahnen sollen die Führungskanäle an ihren den Warenebahnen zugewandten Seiten mit Leitblechen für die Warenbahnen versehen sein.Expediently, sliding guides for the external measuring heads can be provided in the guide channels and / or on the outer heads. For the perfect guidance of the material webs Guide channels can be provided on their sides facing the webs with baffles for the webs.

Die Mittel zur Durchströmung der Warenbahnen mit den Sensoren können gegebenenfalls über Regeleinrichtungen mit Mitteln für die Einstellung des Liniendruckes von Quetschwalzen in Verbindung stehen. Dabei können als Mittel zur Einstellung des Liniendruckes der Quetschwalzen beispielsweise in an sich bekannter Weise hydraulische Zylinder dienen, die zum einen mit dem Walzenkern und zum anderen mit dem Mantelrohr einer als Mantelrohwalze ausgebildeten Quetschwalze verbunden sind.The means for the flow through the material webs with the sensors can, if necessary, be connected to means for adjusting the line pressure of squeeze rollers via control devices. Hydraulic cylinders can be used as a means for adjusting the line pressure of the squeeze rolls, for example in a manner known per se, which are connected on the one hand to the roll core and on the other hand to the casing tube of a squeeze roll designed as a casing pipe roll.

In den Fig. 1 und 2 ist mit 10 eine Warenbahn bezeichnet, auf die in einer Flottenauftragvorrichtung 12 beispielsweise eine Farbflotte aufgetragen wird. Hinter der Flottenauftragvorrichtung ist ein Foulard 11 angeordnet, durch den überschüssige Flotte von der Warenbahn abgequetscht und gleichzeitig eine Vergleichmäßigung der Flottenverteilung auf der Warenbahn erreicht wird.In FIGS. 1 and 2, 10 denotes a web onto which, for example, a liquor of paint is applied in a fleet application device 12. Behind the fleet application device a foulard 11 is arranged through which excess liquor is squeezed off the web and at the same time an equalization of the liquor distribution on the web is achieved.

Während bisher die Feuchtigkeit der Warenbahn zur Einstellung des Liniendruckes der Quetschwalzen über die Warenbahnbreite nach der Flottenauftragvorrichtung durch berührungsfreie Feuchtigkeitsmesser mit den eingangs genannten Mängeln gemessen wurde, ist in Fig. 1 vor der Flottenauftragvorrichtung ein Düsenkopf 13 angeordnet, der durch ein Gewicht 14 mit definiertem Druck auf der Warenbahn aufliegt. Durch den Düsenkopf wird ein definierter konstanter Luftstrom auf die Warenbahn aufgeblasen und mittels eines Staudruckmessers 15 der mit wechselnder Druchlässigkeit der Warenbahn sich ändernde Staudruck gemessen. Die Meßwerte werden an einen Microprozessor 19 gegeben, durch den dann der Liniendruck der Abquetschung der Warenbahn über die Warenbahnbreite gesteuert wird.So far, the moisture of the web for setting the line pressure of the squeeze rolls over the web width after the fleet application device was measured by non-contact moisture meters with the above-mentioned defects, in Fig. 1 a nozzle head 13 is arranged in front of the fleet application device, which is defined by a weight 14 with a defined pressure lies on the web. A defined, constant air flow is inflated onto the material web by the nozzle head and the dynamic pressure which changes with changing permeability of the material web is measured by means of a dynamic pressure meter 15. The measured values are sent to a microprocessor 19, which then controls the line pressure of the pinching off of the web over the web width.

In Fig. 2 ist der in Fig. 1 dargestellte Düsenkopf für die Staudruckmessung durch einen Saugdüsenkopf 16 ersetzt, mit dem unterschiedliche Luftströme durch unterschiedliche Durchlässigkeit der trockenen Warenbahn beispielsweise mittels Drosselblenden 17 und Geschwindigkeitsmessern 18 gemessen werden. Die Meßwerte werden auch hier an einen Microprozessor 19 zur Übernahme der Steuerungs- und Regelungsaufgaben für den Liniendruck der Foulardwalzen gegeben.In FIG. 2, the nozzle head shown in FIG. 1 for the dynamic pressure measurement is replaced by a suction nozzle head 16, with which different air flows are measured through different permeability of the dry fabric web, for example by means of throttle orifices 17 and speedometers 18. The measured values are also given here to a microprocessor 19 for taking over the control tasks for the line printing of the paddle rollers.

Bei der in Fig. 3 und 4 dargestellten Vorrichtung sind oberhalb und gegebenenfalls auch noch unterhalb der zu behandelnden noch trockenen Warenbahnen 10, Meßköpfe 29 angeordnet. Die Meßköpfe sind über die Warenbahnbreite verschieblich gelagert, so daß auch bei unterschiedlich breiten Warenbahnen immer eine optimale Lage der Meßköpfe an den Warenbahnen, z.B. ohne daß Faltenbildungen an den Warenbahnen auftreten können, einstellbar ist.In the device shown in FIGS. 3 and 4, measuring heads 29 are arranged above and, if appropriate, also below the still dry webs 10 to be treated. The measuring heads are slidably supported across the width of the web, so that even with webs of different widths, the measuring heads are always optimally positioned on the webs, e.g. can be set without wrinkling on the webs.

Die Meßköpfe, die mit einer flexiblen Luftzufuhr 32 verbunden sein sollen, sind in Führungskanälen 27 auf Gleitführungen 30 verschieblich gelagert. Die Führungskanäle werden durch sich über die Breite der Warenbahnen erstreckende Traversen 28, die an einem Traggestell befestigt sind, gehalten.The measuring heads, which are to be connected to a flexible air supply 32, are displaceably mounted in guide channels 27 on sliding guides 30. The guide channels are held by cross members 28 which extend across the width of the material webs and which are fastened to a supporting frame.

Wie in diesen Figuren angedeutet ist, laufen die Warenbahnen 10, wenn in die Meßköpfe 29 keine Luft eingeführt wird an den Warenleitblechen 21 anliegend an den Meßköpfen vorbei. Bei Luftbeaufschlagung heben sich die Warenbahnen geringfügig ab und laufen am Meßkopf im Abstand Δh vorbei. Der Staudruck eines konstanten und definierten Luftstromes beim Aufblasen auf die Warenbahnen bis zu deren geringfügigem Aufheben von dem Meßköpfen gibt ein Maß für die Luftdurchlässigkeit der Warenbahnen, welches auch bei dieser Vorrichtung zur Einstellung des Liniendruckes von z.B. Foulardwalzen verwendet werden kann.As indicated in these figures, the webs of goods 10 run past the measuring heads, if no air is introduced into the measuring heads 29, past the product guide plates 21. When exposed to air, the material webs rise slightly and run past the measuring head at a distance of Δh. The dynamic pressure of a constant and defined air flow when inflating onto the webs until they are slightly removed from the measuring heads gives a measure of the air permeability of the webs, which can also be used in this device for setting the line pressure of, for example, paddle rollers.

Eine geeignete Ausbildung eines Foulards ist in Fig. 3 dargestellt. Dabei wird die Warenbahn 10 zwischen Walzen 24 und 25 abgequetscht. Die Walzen sind üblicherweise mit einer elastischen Beschichtung 26 versehen. Um die Druckverteilung über die Warenbahnbreite beeinflussen zu können, kann das Mantelrohr 23 der Walze 25 sowohl in der Mitte über die Achse des Walzenkerns 22 durch die äußeren Zylinder 20 als auch an den Enden über die inneren Zylinder 21 belastet werden. Erfolgt die Belastung vorwiegend durch die Zylinder 20, so wird die Bahn stärker in der Mitte als an den Kanten abgequetscht. Wird der Druck in den Zylinderen 21 höher eingestellt, so werden die Kanten stärker abgequetscht. Gesteuert werden die Zylinder über den Microprozessor 19 in Abhängigkeit von den Meßwerten für die Luftdurchlässigkeit der Warenbahn an den Düsenköpfen 13 bzw. 16, wodurch sich beispielsweise beim Färben mit einfachen Mitteln eine Einstellung gleichmäßiger Behandlungsmittelaufträge auf laufenden Warenbahnen erzielen läßt.A suitable design of a foulard is shown in Fig. 3. The web 10 is squeezed between rollers 24 and 25. The rollers are usually provided with an elastic coating 26. In order to be able to influence the pressure distribution over the width of the web, the casing tube 23 of the roller 25 can be loaded both in the middle via the axis of the roller core 22 by the outer cylinders 20 and at the ends by the inner cylinders 21. If the load is predominantly caused by the cylinders 20, the web is squeezed more in the middle than at the edges. If the pressure in the cylinders 21 is set higher, the edges are squeezed more. The cylinders are controlled by the microprocessor 19 as a function of the measured values for the air permeability of the material web at the nozzle heads 13 and 16, which, for example, enables uniform treatment agent orders to be set on running material webs during dyeing.
