Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Auftragen von Avivagen auf einen laufenden textilen Faden oder ein laufendes textiles Garn auf einer ein Maschinenterminal aufweisenden Textilmaschine, mit einem Behälter für die Avivage, einem durch eine Applikationsdüse gebildeten Applikationsorgan für deren Auftrag, und mit einem Dosiersystem für die gesteuerte Förderung des aufzutragenden Mediums.The present invention relates to a device for applying Avivagen on a running textile thread or a running textile yarn on a machine terminal having a textile machine, with a container for the lubricant, an application nozzle formed by an application member for the order, and with a metering system for the Controlled promotion of the medium to be applied.

Unter Avivage versteht man Textilhilfsmittel wie beispielsweise Emulsionen von Pflanzen und Mineralölen, die das Verhalten von Fäden bei der Weiterverarbeitung verbessern. Die Behandlung der Fäden mit Avivage bezeichnet man als avivieren. Bekannte Einrichtungen zum Auftragen von Avivagen, wie sie beispielsweise zur Herstellung von Nähzwirn verwendet werden, bestehen aus einem Badbehälter und einer rotierend angetriebenen Abgabewalze welche teilweise in ein Avivagebad im Badbehälter eintauchen. Der Faden tangiert die Abgabewalze auf einem Teilbereich ihres nach oben gerichteten Umfangs ohne in das Avivagebad einzutauchen und ist so geführt, dass er die Abgabewalze in einem Winkel tangiert, der um einige Grad von der Senkrechten zur Rotationsachse der Abgabewalze abweicht. Durch diese Anordnung ist gewährleistet, dass sich der Faden auf der Oberfläche der Abgabewalze geringfügig abwälzt und an seinem ganzen Umfang vom Avivagemittel benetzt wird.Auxiliaries are textile auxiliaries such as, for example, emulsions of plants and mineral oils, which improve the behavior of threads during further processing. The treatment of the threads with Avivage is called avivage. Known devices for applying finishing agents, as used for example for the production of sewing thread, consist of a bath container and a rotating driven discharge roller which partially immerse in a bath in the bath tank. The yarn tangles the dispensing roll on a portion of its upwardly directed periphery without dipping into the bath and is guided so as to tangent the dispensing roll at an angle that deviates by a few degrees from the normal to the axis of rotation of the dispensing roll. By this arrangement it is ensured that the thread on the surface of the delivery roller rolls slightly and is wetted on its entire circumference by the lubricant.

Bei dieser in der DE-A-35 30 936 beschriebenen Einrichtung besteht praktisch keine Möglichkeit, die Menge der aufzutragenden Avivage ohne umfangreiche Eingriffe in die Maschine zu beeinflussen, so dass in der Regel zu viel Avivage auf den Faden aufgetragen wird, was zu einer verstärkten Verschmutzung der betreffenden Maschine führt. Ausserdem führt der direkte Auftrag durch die Abgabewalze zu einer Verschmutzung der Umgebung.In this device described in DE-A-35 30 936, there is virtually no possibility to influence the amount of lubricant to be applied without extensive intervention in the machine, so that usually too much brushing is applied to the thread, resulting in a reinforced Contamination of the machine concerned. In addition, direct application by the delivery roller leads to pollution of the environment.

Bei einer in der DE-A-198 17 418 beschriebenen Einrichtung für die Avivierung eines Faserstranges wird der Druck der die Avivage auftragenden Düse(n) in Abhängigkeit von der Geschwindigkeit des Faserstrangs gesteuert, wobei die Steuerung des Durchsatzes an Avivage von der Geschwindigkeit des Faserstrangs erfolgt.In a device for the refinement of a fiber strand described in DE-A-198 17 418, the pressure of the brushing nozzle (s) is controlled as a function of the speed of the fiber strand, wherein the control of the throughput of the fiber strand speed he follows.

Durch die Erfindung soll nun eine Einrichtung der eingangs genannten Art angegeben werden, welche eine Berechnung der gewünschten Auftragsmenge und eine Beeinflussung der aufzutragenden Avivage-Menge ohne Eingriff in die Maschine ermöglicht, bei der es nur zu geringen Maschinen- und Umweltverschmutzungen kommt, undThe invention will now be a device of the type mentioned above, which allows a calculation of the desired order quantity and influencing the amount of lubricant to be applied without intervention in the machine, in which there are only minor machine and environmental pollution, and

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Dosiersystem eine an einen Geber für die Garngeschwindigkeit angeschlossene Steuereinheit aufweist, und dass im Maschinenterminal oder in der Steuereinheit die gewünschte Auftragsmenge für die einzelnen Fadenmaterialien auf Grund der in das Maschinenterminal eingegebenen Werte für Material und die Spulgeschwindigkeit berechnet wird.This object is achieved according to the invention in that the dosing system has a control unit connected to a yarn speed sensor and that the desired application quantity for the individual yarn materials is calculated in the machine terminal or in the control unit on the basis of the values for material and the winding speed entered into the machine terminal becomes.

In der DE-C-43 33 716 ist ein Verfahren und eine Vorrichtung zum Aufbringen von Avivagen (Präparationen) auf Garne oder Fäden beschrieben, mit welcher ein bei Raumtemperatur fliessfähiges Präparationsmittel unmittelbar vor dem Auftrag erhitzt und direkt appliziert wird. Das wesentliche Merkmal der in der DE-C-43 33 716 beschriebenen Erfindung besteht in der Erhitzung des bei Raumtemperatur fliessfähigen Präparationsmittels, wodurch ein schädliches Separieren und damit eine Änderung der Zusammensetzung von im heissen Zustand nicht mischbaren Bestandteilen des Präparationsmittels ausgeschlossen werden soll. Zum Auftrag selbst heisst es in dieser Patentschrift zwar, dass das Präparationsmittel in der erforderlichen Menge appliziert wird, und dass die Vorrichtung zum Aufbringen der Präparation eine Dosiervorrichtung zum Einstellen der zugeführten Menge des Präparationsmittel aufweist, es fehlt aber jede Offenbarung, wie die erforderliche Menge eingestellt wird. Es ist daher davon aus zu gehen, dass die Dosiervorrichtung eventuell auf eine gewünschte Fördermenge einstellbar ist, dass aber jede Möglichkeit der Beeinflussung oder Steuerung der einmal eingestellten Fördermenge während des Aufbringens des Präparationsmittels fehlt. Die erfindungsgemässe Einrichtung eröffnet diese Möglichkeit und stellt somit sowohl in ökonomischer als auch in ökologischer Hinsicht eine wesentliche Verbesserung dar.DE-C-43 33 716 describes a method and a device for applying coatings (preparations) to yarns or threads, with which a preparation which is flowable at room temperature is heated immediately before the application and applied directly. The essential feature of the invention described in DE-C-43 33 716 is the heating of the flowable at room temperature preparation, whereby a harmful separation and thus a change in the composition of immiscible in the hot state components of the preparation should be excluded. For the order itself, although it is stated in this patent specification that the spin finish is applied in the required amount, and that the device for applying the preparation has a dosing device for adjusting the amount of spin finish supplied, but there is no disclosure of how to adjust the required amount becomes. It is therefore to be assumed that the metering device may be adjustable to a desired flow rate, but that there is no possibility of influencing or controlling the once set flow rate during the application of the spin finish. The device according to the invention opens up this possibility and thus represents a significant improvement in terms of both economy and ecology.

Gemäss einer ersten bevorzugten Ausführungsform ist der genannte Geber durch ein Maschinenterminal oder einen Sensor für die Garngeschwindigkeit gebildet.According to a first preferred embodiment, said encoder is formed by a machine terminal or yarn speed sensor.

Die erfindungsgemässe Lösung ermöglicht eine von der Garngeschwindigkeit abhängige Dosierung des aufzutragenden Mediums, so dass auch bei Geschwindigkeitsänderungen ein konstanter Auftrag auf den Faden garantiert ist. Die Information über die Garngeschwindigkeit erhält die Steuereinheit des Dosiersystems von der Maschinensteuerung, oder falls von dieser die gewünschte Information nicht erhältlich ist, von einem Sensor für die Garngeschwindigkeit.The solution according to the invention enables a metering of the medium to be applied, which depends on the yarn speed, so that a constant application to the yarn is guaranteed even with changes in speed. The yarn speed information is provided to the dosing system control unit by the machine control or, if the desired information is not available, from a yarn speed sensor.

Eine zweite bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass eine Heizeinrichtung für die Ermöglichung des Auftrags von zähflüssiger Avivage vorgesehen ist.A second preferred embodiment is characterized in that a heating device is provided for facilitating the application of viscous finishing agent.

Eine dritte bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass das Dosiersystem eine von einem Schrittmotor antreibbare Pumpe aufweist.A third preferred embodiment is characterized in that the dosing system comprises a pump drivable by a stepper motor.

Eine vierte bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass die Applikationsdüse durch eine vom Faden durchlaufene, ringförmige Düse gebildet ist.A fourth preferred embodiment is characterized in that the application nozzle is formed by an annular nozzle passed through by the thread.

Die Erfindung betrifft weiter eine Verwendung der genannten Einrichtung zum Auftragen von Avivagen auf einer ein Maschinenterminal aufweisenden Spulmaschine.The invention further relates to a use of said device for applying avivages on a machine terminal having a winding machine.

Eine bevorzugte Ausführungsform dieser Verwendung ist dadurch gekennzeichnet, dass der Steuereinheit des Dosiersystems der momentane Durchmesser der auf der Spulmaschine hergestellten Spule zugeführt und dass die Fördermenge des aufzutragenden Mediums vom Spulendurchmesser beeinflusst ist.A preferred embodiment of this use is characterized in that the control unit of the dosing fed to the instantaneous diameter of the bobbin produced on the winder and that the delivery rate of the medium to be applied is influenced by the bobbin diameter.

Diese Verwendung hat den Vorteil, dass auf dem Faden ein vom Durchmesser der Spule abhängiges Auftragsprofil erstellt werden kann, also mit einem nicht konstanten Avivage-Auftrag gearbeitet wird, was für bestimmte Anwendungsfälle vorteilhaft ist.This use has the advantage that on the thread a dependent of the diameter of the coil order profile can be created, that is, working with a non-constant finishing order, which is advantageous for certain applications.

Im Folgenden wird die Erfindung an Hand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert; es zeigt:

Fig. 1
eine schematische Darstellung einer mit einer erfindungsgemässen Einrichtung zur Auftragen von Avivagen ausgerüsteten Spulstation einer Spulmaschine; und

In the following the invention will be explained in more detail with reference to an embodiment shown in the drawings; it shows:
Fig. 1
a schematic representation of an equipped with a device according to the invention for applying coatings Avivagen winding station of a winding machine; and
Fig. 2
a block diagram of the device for applying Avivagen.

Die in Fig. 1 dargestellte Spulstation besteht im wesentlichen aus einer Aufsteckung 1 zur Aufnahme einer Vorlagespule 2 mit einem Faden 3, einer Avivageeinrichtung 4 zum Auftragen von Avivagen, einer Fadenbremse 5, einem Maschinenterminal 6 und aus einem Spulaggregat 7. Das Maschinenterminal 6 enthält die verschiedenen Spulprogramme und dient einerseits zur Eingabe der für den Spulprozess relevanten Daten, wie beispielsweise Spulmaterial (Stapel-, Filamentgarn, texturiertes Garn), Spulgeschwindigkeit, usw.) und andererseits zur Steuerung der angeschlossenen Komponenten der Spulstation.The winding station shown in Fig. 1 consists essentially of a Aufsteckung 1 for receiving a feed bobbin 2 with a thread 3, a lubrication device 4 for applying Avivagen, a yarn brake 5, a machine terminal 6 and a winding unit 7. The machine terminal 6 contains the different spooling programs and serves on the one hand to enter the relevant data for the winding process, such as winding material (staple, filament yarn, textured yarn), winding speed, etc.) and on the other hand to control the connected components of the winding station.

Das Spulaggregat 7 besteht aus einer durch einen Motor 8 antreibbaren Spindel 9 zur Aufnahme und Halterung einer Spulenhülse 10, auf die eine Spule 11 aufgewickelt wird, einer nicht dargestellten Einrichtung zur Verlegung des Fadens 3 auf der Spule 11 und einer frei drehbaren Walze 12, an der die Spule 11 anliegt. Die Walze 12 ist auf einem geeigneten Trägerteil 13 der Spulmaschine montiert. Bezüglich der Einrichtung zur Verlegung des Fadens 3 wird beispielsweise auf die EP-A-1 125 878 und die EP-A-1 210 423 verwiesen.The winding unit 7 consists of a drivable by a motor 8 spindle 9 for receiving and holding a bobbin 10, on which a coil 11 is wound, a device, not shown, for laying the thread 3 on the spool 11 and a freely rotatable roller 12 at the coil 11 is applied. The roller 12 is mounted on a suitable support part 13 of the winding machine. With regard to the device for laying the thread 3, reference is made, for example, to EP-A-1 125 878 and EP-A-1 210 423.

Die Spulstation enthält ausserdem noch eine Steuereinheit 14 für die Avivageeinrichtung 4 sowie einen in Fadenlaufrichtung vor der Fadenbremse 5 angeordneten Einlaufteil und einen nach der Fadenbremse angeordneten Auslaufteil. Da die letzteren Elemente bekannt sind und auch nicht Gegenstand der vorliegenden Erfindung bilden, sind sie nicht dargestellt.The winding station also contains a control unit 14 for the lubrication device 4 and arranged in the direction of yarn travel before the yarn brake 5 inlet part and arranged after the yarn brake outlet part. Since the latter elements are known and do not form the subject of the present invention, they are not shown.

Die in Fig. 2 dargestellte Avivage-Einrichtung 4 besteht aus einer Applikationsdüse 15 für das Auftragen von Avivage auf den Faden 3, einem einen Schrittmotor 16 und eine Zahnradpumpe 17 enthaltenden Dosiersystem für die gesteuerte Förderung der Avivage aus einem Vorratsbehälter 18 zur Applikationsdüse 15, und aus einem Heizelement 19. Der Schrittmotor 16 und das Heizelement 19 sind an die Steuereinheit 14 angeschlossen und von dieser gesteuert. Im Bereich der Applikationsdüse 2 ist ein mit der Steuereinheit 14 verbundener Temperatursensor 20 für die Messung der Temperatur der der Applikationsdüse 15 zugeführten Avivage vorgesehen. Die Applikationsdüse 15 kann seitlich neben dem Faden angeordnet sein und die Avivage unter einem rechten oder einem spitzen Winkel auf den Faden applizieren, oder sie kann als Ringdüse ausgebildet und vom Faden F durchlaufen sein. Letzteres ermöglicht einen allseitigen und gleichmässigen Auftrag von Avivage.The lubrication device 4 shown in FIG. 2 consists of an application nozzle 15 for applying lubricant to the yarn 3, a metering system containing a stepper motor 16 and a gear pump 17 for the controlled delivery of the lubricant from a reservoir 18 to the application nozzle 15, and from a heating element 19. The stepper motor 16 and the heating element 19 are connected to the control unit 14 and controlled by this. In the area of the application nozzle 2, a temperature sensor 20 connected to the control unit 14 for measuring the temperature of the application nozzle 15 supplied with the lubricant is provided. The application nozzle 15 can be arranged laterally next to the thread and apply the finish to the thread at a right angle or at an acute angle, or it can be designed as an annular die and run through by the thread F. The latter allows an all-round and even order from Avivage.

Die Geschwindigkeit des Fadens F wird im Maschinenterminal 6 oder in einem mit diesem verbundenen Rechner aus Drehzahl und Durchmesser der Spule 11 berechnet und der Steuereinheit 14 zugeführt. Diese steuert den Schrittmotor 16 so, dass auf den Faden 3, unabhängig von dessen Geschwindigkeit, die gleiche einstellbare Menge an Avivage aufgetragen wird. Die Auftragsmenge an Avivage wird also geschwindigkeitsabhängig dosiert und es wird auch bei Änderungen der Fadengeschwindigkeit (z.B. anderes Spulrezept, Rampen, und dergleichen) ein konstanter Auftrag auf den Faden garantiert. Die gewünschte Auftragsmenge ist für die einzelnen Fadenmaterialien für eine bestimmte Geschwindigkeit bekannt und wird im Maschinenterminal oder in der Steuereinheit auf Grund der in das Maschinenterminal 6 eingegebenen Werte für das Material und die Spulgeschwindigkeit berechnet. Am Maschinenterminal 6 können beliebige Geschwindigkeits- und Fördermengenprofile spul- oder prozessabhängig zentral für alle Spulpositionen eingegeben werden. Die Auftragsmenge wird üblicherweise in Prozent angegeben, wobei sich die Prozentangabe auf das Gewicht des gespulten Garns bezieht. Wenn man beispielsweise von einer Avivage-Auftragsmenge von 10% spricht, dann bedeutet das, dass auf 100 g gespultes aviviertes Garn 10 g Avivage aufgetragen sind. Übliche Auftragsmengen von Avivage liegen zwischen 1.5% und 12%.The speed of the thread F is calculated in the machine terminal 6 or in a computer connected thereto from the speed and diameter of the coil 11 and fed to the control unit 14. This controls the stepper motor 16 so that on the thread 3, regardless of its speed, the same adjustable amount of lubricant is applied. The application amount of lubricant is thus dose-dependent, and a constant application to the yarn is guaranteed even with changes in the yarn speed (for example, other winding recipe, ramps, and the like). The desired application quantity is known for the individual thread materials for a certain speed and is calculated in the machine terminal or in the control unit on the basis of the values entered for the material and the winding speed in the machine terminal 6. At the machine terminal 6, any speed and delivery rate profiles can be entered centrally for all winding positions, depending on the spooling or process. The order quantity is usually stated in percent, the percentage being based on the weight of the spooled yarn. For example, if we talk about a 10% application rate, then this means that 10 g of Avivage are applied to 100 g of co-processed, twisted yarn. Usual order volumes of Avivage are between 1.5% and 12%.

Da die Steuereinheit 14 mit dem Maschinenterminal M verbunden ist, kann mit der Avivage-Einrichtung 4 auch ein vom Durchmesser der Spule 11 abhängiges Avivage-Auftragsprofil realisiert werden. Das Maschinenterminal 6 "kennt" den aktuellen Spulendurchmesser, entweder durch Messung mit einem Sensor oder durch Berechnung, und führt diesen Wert der Steuereinheit 14 zu, die das Dosiersystem 16, 17 entsprechend zum gewünschten Auftragsprofil steuert.Since the control unit 14 is connected to the machine terminal M, can be realized with the lubrication device 4 also dependent on the diameter of the coil 11 Avivage job profile. The machine terminal 6 "knows" the current bobbin diameter, either by measurement with a sensor or by calculation, and supplies this value to the control unit 14, which controls the dosing system 16, 17 corresponding to the desired order profile.

Durch das Heizelement 19 ist es möglich, zähflüssige Avivagen zu verflüssigen und heiss aufzutragen. Das Heizelement 19 wird von der Steuereinheit 14 entsprechend angesteuert, wobei der Temperatursensor 20 die Temperatur der Avivage misst und an die Steuereinheit 14 meldet. Bei einem Stopp der Spulstation wird über die Steuereinheit 14 auch die Avivage-einrichtung 4 gestoppt und das Dosiersystem 16, 17 und das Heizelement werden abgestellt.By the heating element 19, it is possible to liquefy viscous lubricants and apply hot. The heating element 19 is controlled accordingly by the control unit 14, wherein the temperature sensor 20 measures the temperature of the lubricant and reports it to the control unit 14. When the winding station stops, the lubricating device 4 is also stopped by the control unit 14 and the metering system 16, 17 and the heating element are switched off.

Die Verwendung der Avivage-Einrichtung an einer Spulmaschine ist nur als beispielhaft und nicht als einschränkend zu verstehen. Die Avivage-Einrichtung 4 kann an jeder beliebigen Garnherstellungs-, Garnverarbeitungs- oder Garnveredelungsmaschine eingesetzt werden.The use of the lubrication device on a winder is to be understood as illustrative only and not as limiting. The finishing device 4 can be used on any yarn making, yarn processing or yarn finishing machine.

Die besonderen Vorteile der Avivage-Einrichtung 4 mit dem Dosiersystem 16, 17 bestehen darin, dass Variable, wie Spulgeschwindigkeit und unterschiedliche Garnmaterialien kompensiert werden können und stets die gewünschte, gleichbleibende Avivagemenge aufgetragen wird. Das eröffnet die Möglichkeit, nur so viel Avivage aufzutragen, wie erforderlich ist, was zu einer deutlichen Reduktion der Verschmutzung der Maschine führt.The particular advantages of the lubrication device 4 with the dosing system 16, 17 are that variable, such as winding speed and different yarn materials can be compensated and always the desired, consistent Avivagemenge is applied. This opens up the possibility of applying only as much finish as required, which leads to a significant reduction in the contamination of the machine.

Ein weiterer Vorteil liegt in der Applikationsdüse 15. Da diese die Avivage direkt auf den die Düse durchlaufenden Faden 3 aufträgt, wird auch die Verschmutzung der Umgebung sehr stark reduziert. Ein zusätzlicher Vorteil der Avivage-Einrichtung 14 besteht in der Möglichkeit der Realisierung eines vom Durchmesser der Spule abhängigen Avivage-Auftragsprofils, was für bestimmte Anwendungsfälle erwünscht ist.Another advantage lies in the application nozzle 15. Since this applies the lubricant directly to the thread passing through the nozzle 3, the pollution of the environment is greatly reduced. An additional advantage of the lubrication device 14 is the possibility of realizing a coil diameter dependent application profile, which is desirable for certain applications.
