Abstract

A yarn-treatment device comprises a column of chambers connected by yarn-inlet and yarn-outlet channels. The chambers contain a stream treatment chamber (5) with a steam inlet (5.1) and a condensate outlet (5.2), and mixing chambers (4, 6) operating upstream and downstream of the treatment chamber. Each mixing chamber has an air inlet (4.1, 6.1) and a condensate outlet (4.2, 6.2). The yarn inlet and outlet channels of the stream treatment chamber have an opening cross section to make a pneumatic yarn threading-in, and to control the exchange of air and steam between the chambers, such that the steam-air-mixture atmosphere sets in, to close the entrance of air into the steam treatment chamber. The steam-air-mixture atmosphere is controlled by regulation devices that regulate the steam and air supply to the steam treatment chamber or respective mixing chambers. The downstream mixing chamber is connected to a cooling and drying chamber (7), and includes a jet connected with protection plates. The treatment device further comprises yarn delivery rollers (11, 12) at upper and lower ends of the column of chambers.

Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1. Diese Vorrichtung kann insbesondere als Thermofixiereinrichtung dienen, bei der der laufende Faden in einer Dampfbehandlungszone erhitzt und anschließend in einer Kühl- und Trocknungszone so abgekühlt und getrocknet wird, dass er seinen in der Dampfbehandlungszone erreichten Zustand beibehält.The invention relates to a device according to the preamble of claim 1. This device can serve, in particular, as a thermofixing device, in which the running thread is heated in a steam treatment zone and then cooled and dried in a cooling and drying zone so that it reaches its in the steam treatment zone Condition is maintained.

Der Begriff "Dampf" steht stellvertretend auch für andere gasförmige Medien.The term "steam" is representative of other gaseous media.

Ziel einer derartigen Behandlung ist es, durch eine definierte Schrumpfung oder Dehnung das Volumen bzw. die Dichte eines Textilfadens zu beeinflussen und zu steuern, wobei beispielsweise durch eine gezielte Schrumpfung das Volumen des Textilfadens, der sog. Bausch, erhöht werden kann. Wesentlich dabei ist es, die Optimierung und Konservierung der dem Faden in der Dampfbehandlungszone erteilten physikalischen Effekte durch Abkühlung und Trocknung des behandelten Fadens möglichst vollständig aufrechtzuerhalten, und zwar auch bei und nach dem Aufspulen des Fadens zu einer Spule.The aim of such a treatment is to influence and by a defined shrinkage or elongation, the volume or density of a textile thread control, for example, by a targeted shrinkage, the volume of the textile thread, the so-called Bausch, can be increased. It is essential to maintain the optimization and preservation of the physical effects of the thread in the steam treatment zone by cooling and drying of the treated thread as fully as possible, even during and after the winding of the thread into a coil.

Bei einer in der EP 1 348 785 beschrieben Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 schließt an die dem Dampfbehandlungsraum nachgeschaltete Trennkammer eine Kühlstrecke in Form eines relativ engen Fadenlaufkanals an, in den Kühlluft eingeblasen werden kann. Der Nachteil dieser bekannten Vorrichtung besteht darin, dass die Kühllufteinspeisung in einem sehr engen Kanal stattfindet, so dass der Kühl- und Trocknungseffekt nur sehr gering ist.At one in the EP 1 348 785 Device according to the preamble of patent claim 1 connects to the downstream of the steam treatment chamber separation chamber to a cooling section in the form of a relatively narrow yarn path, can be blown into the cooling air. The disadvantage of this known device is that the cooling air supply takes place in a very narrow channel, so that the cooling and drying effect is very low.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der in der EP 1 348 785 A1 beschriebenen Art so zu verbessern, dass der nach der Dampfbehandlung aus der Vorrichtung austretende Faden schnell so weit abgekühlt und getrocknet wird, dass bei und nach dem Aufwickeln zu einer Spule die Fadenqualität verschlechternden Zustandsänderungen weitgehend ausgeschlossen sind.The invention has for its object to provide a device in the EP 1 348 785 A1 described type to be improved so that the exiting the steam treatment from the device thread is quickly cooled and dried so far that during and after winding to a coil, the yarn quality deteriorating state changes are largely excluded.

Diese Aufgabe wird mit einer Vorrichtung gemäß Patentanspruch 1 gelöst.This object is achieved with a device according to claim 1.

Der Gesamtaufbau der Vorrichtung einschließlich ihrer Funktionsweise wird im folgenden anhand der Zeichnung näher beschrieben.

  • Figur 2 ist ein Horizontalschnitt im Bereich der Kühlkammer.
  • Figur 3 ist ein Schemabild der Anbindung einer Fadenbehandlungsstrecke an das Steuer- und Regelsystem einer Vielstellenmaschine.
The overall structure of the device including its operation will be described below with reference to the drawing.
  • FIG. 1 shows an axial section of the device with connected Kondensatableititeinrichtung;
  • FIG. 2 is a horizontal section in the area of the cooling chamber.
  • FIG. 3 is a schematic of the connection of a thread treatment line to the control system of a multi-station machine.

Die erfindungsgemäße Vorrichtung besteht aus mehreren insbesondere vertikal übereinander angeordneten, mit Dampf bzw. Druckluft beaufschlagbaren Kammern, wobei benachbarte Kammern jeweils mittels zentral übereinander angeordneten Fadeneinlauf- und Fadenauslaufkanälen aneinander angeschlossen sind, deren Öffnungsquerschnitte so gestaltet sind, dass einerseits eine pneumatische Fadendurchfädelung durch die Fadeneinlauf- und Fadenauslaufkanäle sämtlicher Kammern möglich ist, während andererseits ein Eindringen von Luft aus den an die Dampfbehandlungskammer angrenzenden Kammern weitgehend ausgeschlossen sein soll.The inventive device consists of several in particular vertically stacked, can be acted upon with steam or compressed air chambers, adjacent chambers are connected to each other by means centrally centrally arranged Fadeneinlauf- and thread outlet channels, whose opening cross-sections are designed so that on the one hand a pneumatic thread through the Fadeneinlauf- and thread outlet channels of all chambers is possible, while on the other hand, penetration of air from the adjoining the steam treatment chamber chambers should be largely excluded.

Die Vorrichtung enthält eine obere Vorkammer 3, in der ein Lieferwerk 11 für den Faden F untergebracht ist. Auf die Vorkammer 3 folgt eine vorzugsweise aus wärmeisolierendem Material, insbesondere Keramikmaterial, bestehende Mischkammer 4, die einen Lufteinlass 4.1 und einen Kondensatauslass 4.2 aufweist. Auf die Mischkammer 4 folgt eine Dampfbehandlungskammer 5, die einen Dampfeinlass 5.1 sowie einen verschließbaren Kondensatauslass 5.2 hat. Auf die Dampfbehandlungskammer 5 folgt eine vorzugsweise aus Keramikmaterial bestehende, relativ großvolumige Kühlkammer 6, die einen Lufteinlass 6.1 für unter Druck stehende Kühlluft sowie einen Kondensatauslass 6.2 hat. In dieser Kühlkammer 6 mit einem Innendurchmesser im Bereich von 70 - 90 mm, vorzugsweise etwa 80 mm, und einer Höhe im Bereich von 25 - 35 mm, vorzugsweise ca. 30 mm, findet eine wesentliche Kondensation des Dampfes und damit auch eine Trocknung des Fadens statt, derart, dass bereits bis zu 90 % und mehr des insgesamt bei der Kühlung anfallenden Kondensats sich an den Kammerwänden niederschlägt und durch den Kondensatauslass 6.2 abgeführt wird. Durch den Lufteinlass 6.1 ist eine in der Nähe des Fadenlaufweges endende Düse 13 hindurchgeführt, an die sich gemäß Figur 2 vorzugsweise seitlich des Fadenlaufweges liegende Abschirmplatten 14 anschließen. Auf die Kühlkammer 6 folgt eine weitere Kühl- und Trocknungskammer 7, in die Kühlluft durch den die beiden Kammern 6 und 7 verbindenden Fadenkanal einströmt und die einen Kondensatauslass 7.2 aufweist. Auf die Kühl- und Trocknungskammer 7 folgt eine Endkammer 8, an deren Ende ein zweites Fadenlieferwerk 12 untergebracht ist.The device includes an upper pre-chamber 3, in which a delivery mechanism 11 is housed for the thread F. On the pre-chamber 3 is followed by a preferably made of heat-insulating material, in particular ceramic material, existing mixing chamber 4, which has an air inlet 4.1 and a condensate outlet 4.2. The mixing chamber 4 is followed by a steam treatment chamber 5, which has a steam inlet 5.1 and a closable condensate outlet 5.2. The steam treatment chamber 5 is followed by a relatively large-volume cooling chamber 6, preferably made of ceramic material, which has an air inlet 6.1 for pressurized cooling air and a condensate outlet 6.2. In this cooling chamber 6 with an inner diameter in the range of 70-90 mm, preferably about 80 mm, and a height in the range of 25-35 mm, preferably about 30 mm, finds a significant condensation of the vapor and thus a drying of the thread instead, such that already up to 90% and more of the total resulting in the cooling condensate precipitates on the chamber walls and is discharged through the condensate outlet 6.2. Through the air inlet 6.1 an ending in the vicinity of the thread running path nozzle 13 is passed to the according to FIG. 2 preferably laterally of the yarn path lying shield plates 14 connect. The cooling chamber 6 is followed by a further cooling and drying chamber 7, into which cooling air flows through the thread channel connecting the two chambers 6 and 7 and which has a condensate outlet 7.2. The cooling and drying chamber 7 is followed by an end chamber 8, at the end of which a second yarn delivery unit 12 is accommodated.

Die beiden Lieferwerke 11 und 12 dienen dem Zweck, den Faden spannungsfrei oder mit möglichst geringer Fadenspannung durch die Vorrichtung laufen zu lassen.The two delivery mechanisms 11 and 12 serve the purpose of running the thread tension-free or with the lowest possible thread tension through the device.

Um ein Einfließen von Kondensat in eine jeweils darunter befindliche Kammer auszuschließen, sind im Bereich der Böden bzw. Fadenauslaufkanälen der Kammern 4, 5, 6 und 7 nach oben vorspringende Rückhaltewehre 4.5, 5.5, 6.5 bzw. 7.5 angeordnet. Der Boden der oberen Vorkammer 3 ist hingegen mit einer den Fadenauslaufkanal umgebenden Einbuchtung 3.1 versehen, um u. U. gebildetes Kondensat aus der Vorkammer ausfließen zu lassen.In order to preclude the inflow of condensate into a respective chamber located underneath, restraining weirs 4.5, 5.5, 6.5 and 7.5, projecting upwards, are arranged in the region of the bottoms or outflow channels of the chambers 4, 5, 6 and 7. The bottom of the upper pre-chamber 3, however, with a the thread outlet channel provided surrounding recess 3.1 to u. U. formed condensate to flow out of the antechamber.

Der Vorkammer 3 ist gemäß Figur 3 die schematisiert dargestellte Fadenschleuse 30 vorgeschaltet, und auf die untere Endkammer 8 folgt ebenfalls eine Fadenschleuse 31. Diese Fadenschleusen 30, 31 bestehen in nicht zur Erfindung gehörender Weise aus länglichen, relativ zueinander beweglichen Fadenführungselementen, die einen Fadenkanal begrenzen, der von dem durchlaufenden Faden so ausgefüll ist, dass der Faden selbst das Dichtungselement bildet, um einen Austritt von Behandlungsmedien aus der Vorrichtung weitgehend zu verhindern.The pre-chamber 3 is according to FIG. 3 The thread sluice 30 shown in schematic form precedes, and the lower end chamber 8 is also followed by a sluice gate 31. These sluice gates 30, 31 consist, in a manner not belonging to the invention, of oblong, relatively movable thread guide elements which delimit a thread channel which is defined by the continuous thread filled is that the thread itself forms the sealing element to prevent leakage of treatment media from the device largely.

Die Vorkammer 3 und die Kühl- und Trocknungskammer 7 sind mit Temperaturfühlern TK ausgerüstet, die an Regelorgane 21a bzw. 21b angeschlossen sind, die die Luftzufuhr in die Kammern 4 und 6 über diesen Kammern 4 und 6 vorgeschaltete Ventile 4.4 bzw. 6.4 steuern.The prechamber 3 and the cooling and drying chamber 7 are equipped with temperature sensors T K , which are connected to control elements 21a and 21b, respectively, which control the supply of air into the chambers 4 and 6 via these chambers 4 and 6 valves 4.4 and 6.4.

Die Dampfbehandlungskammer 5 ist mit Temperaturfühlern TD ausgerüstet, die über ein Regelorgan 22 die Dampfzufuhr in die Dampfbehandlungskammer 5 steuern. Die beiden Regelorgane 21a, 21b sind mit dem Regelorgan 22 verknüpft, um gemeinsam die jeweiligen Druckwerte und damit die Temperaturwerte in den einzelnen Kammern zu regeln bzw. zu steuern.The steam treatment chamber 5 is equipped with temperature sensors T D , which control the steam supply into the steam treatment chamber 5 via a control element 22. The two control elements 21a, 21b are linked to the control element 22 in order to jointly regulate or control the respective pressure values and thus the temperature values in the individual chambers.

In der Kühlkammer 6 ist oberhalb der Düse 13 ein vorzugsweise glockenförmig nach oben gewölbter, bis zur Kammerinnenwand reichender Boden 9 angeordnet, der eine zentrisch liegende Fadenöffnung 9.1 und im Bereich seines unten liegenden, an die Kammerinnenwand angrenzenden Randes mindestens eine Kondensatabflussöffnung 9.2 aufweist. Bei dieser Kammer 6 liegt die Mischzone im wesentlichen oberhalb des Bodens 9, während die Kühlzone unterhalb dieses Bodens liegt. Der glockenförmige Boden 9 führt bereits zu einer weitgehenden Abschottung der unterhalb dieses Bodens befindlichen Kühlzone gegen einen Dampfeintritt, da von dem Faden mitgerissene Dampfpartikel im Bereich der Öffnung 9.1 von dem Faden abgestreift werden. Oberhalb dieses Bodens 9 findet bereits eine erste Kondensatbildung statt, und das dabei gebildete Kondensat fließt durch die Kondensatabflussöffnung 9.2 am Innenwandbereich der Kammer 6 zu dem Kondensatauslass 6.2.In the cooling chamber 6 is above the nozzle 13 a preferably bell-shaped upwardly curved, reaching to the chamber inner wall bottom 9 is arranged, which has a centrally located thread opening 9.1 and at least one condensate drain opening 9.2 in the region of its underlying, adjacent to the chamber inner edge edge. In this chamber 6, the mixing zone is located substantially above the bottom 9, while the cooling zone is below this bottom. The bell-shaped bottom 9 already leads to a large extent foreclosure of the cooling zone located below this bottom against a steam inlet, since entrained by the thread steam particles are stripped in the region of the opening 9.1 of the thread. Above this bottom 9 already takes place a first condensation, and the condensate formed flows through the Condensate drain opening 9.2 on the inner wall region of the chamber 6 to the condensate outlet 6.2.

Die Kühl- und Trocknungskammer 7 enthält mindestens einen vorzugsweise glockenförmig nach oben gewölbten, bis zur Kammerinnenwand reichenden Boden 10, der eine zentrisch angeordnete Fadenöffnung und im Bereich seines unteren, an die Innenwand der Kammer 7 angrenzenden Randes mindestens eine Kondensatabflussöffnung 10.1 hat. Es können vorzugsweise bis zu vier oder mehr dieser glockenförmigen Böden 10 vorgesehen sein.The cooling and drying chamber 7 includes at least one preferably bell-shaped upwardly curved, reaching to the chamber inner wall bottom 10, which has a centrally disposed thread opening and in the region of its lower, adjacent to the inner wall of the chamber 7 edge at least one condensate drain opening 10.1. It may preferably be provided up to four or more of these bell-shaped bottoms 10.

Der Kondensatauslass 5.2 der Dampfbehandlungskammer 5 ist über eine Kondensatleitung 5.3 an einen Kondensatbehälter 15 angeschlossen, dessen Auslass durch ein steuerbares Ventil 16 verschließbar ist, dessen Ventilkörper 16.1 gegen die Kraft einer Feder 17 verstellbar ist.The condensate outlet 5.2 of the steam treatment chamber 5 is connected via a condensate line 5.3 to a condensate tank 15 whose outlet can be closed by a controllable valve 16, the valve body 16.1 against the force of a spring 17 is adjustable.

Die Kondensatauslässe 4.2 bzw. 6.2 bzw. 7.2 der Kammern 4 und 6 sowie der Kühl- und Trockenkammer 7 sind über Leitungen 4.3, 6.3 bzw. 7.3 an Abflusskanäle 18 bzw. 19 bzw. 20 der Kondensatablasseinrichtung 23 angeschlossen, die jeweils Drosseln 18.1 bzw. 19.1 bzw. 20.1 enthalten.The condensate outlets 4.2 and 6.2 or 7.2 of the chambers 4 and 6 and the cooling and drying chamber 7 are connected via lines 4.3, 6.3 and 7.3 to drain channels 18 and 19 and 20 of the condensate drain device 23, the respective throttles 18.1 or 19.1 or 20.1 included.

Die obere Mischkammer 4, der durch den Lufteinlass 4.1 Druckluft zugeführt wird, dient zur Abschottung der Dampfbehandlungskammer 5, um weitgehend zu verhindern, dass Luft in die Dampfbehandlungskammer 5 eindringt, indem sich in dieser Mischkammer 4 durch geeignete Steuerung der in diese Kammer 4 einströmenden Luft eine Dampf-/Luft-/Mischatmosphäre einstellt.The upper mixing chamber 4, which is supplied with compressed air through the air inlet 4.1, serves to seal off the steam treatment chamber 5 in order to largely prevent air from entering the steam treatment chamber 5 by moving in this mixing chamber 4 by suitable control of the air flowing into this chamber 4 sets a steam / air / mixed atmosphere.

Die auf die Dampfbehandlungskammer 5 folgende Kühlkammer 6 dient ebenso wie die obere Mischkammer 4 zum Abschotten der Dampfbehandlungskammer 5 gegen das Eindringen von Luft von unten her. Indem in dieser Kammer 6 die Kühlluft durch das Düsen-/Abschirmplattensystem 13/14 möglichst dicht an den Faden herangeführt wird, erfolgt ein rasches Abkühlen des Fadens, um einen möglichst hohen Thermofixiereffekt zu bewirken. Innerhalb dieser Kammer 6 wird gleichzeitig von dem Faden mitgeführte Feuchte aus dem Faden ausgetrieben, d.h. der Faden wird bereits in einem gewissen Umfang getrocknet. Der oberhalb des Systems 13/14 befindliche glockenförmige Boden 9 führt auch durch "Abstreifen" von Dampf zu einer Dampfabscheidung.The following on the steam treatment chamber 5 cooling chamber 6 is used as well as the upper mixing chamber 4 for Abschotten the steam treatment chamber 5 against the ingress of air from below. By bringing the cooling air through the nozzle / shielding plate system 13/14 as close as possible to the thread in this chamber 6, the thread is rapidly cooled in order to effect the highest possible heat-setting effect. Within this chamber 6 moisture carried along by the thread is driven out of the thread at the same time, ie the thread is already dried to a certain extent. The bell-shaped bottom 9 located above the system 13/14 also leads to a vapor deposition by "stripping" of steam.

Infolge der Verwendung von Keramikmaterial werden die beiden Kammern 4 bzw. 6 gegenüber der Dampfbehanldungskammer 5 thermisch isoliert. Sie werden daher nicht oder nur geringfügig von der anschließenden Dampfbehandlungskammer aufgewärmt, so dass auch nur eine geringe Wärmeenergiemenge diese Kammern 4 bzw. 6 als Energieverlust verlässt. Der Fadendurchlaufkanal zwischen der Dampfbehandlungskammer 5 und der darauf folgenden Kammer 6 ist relativ lang ausgeführt, wodurch eine mechanische Abschottung der Dampfbehandlungskammer 5 bewirkt wird.As a result of the use of ceramic material, the two chambers 4 and 6 are thermally insulated from the Dampfbehanldungskammer 5. They are therefore not or only slightly warmed up by the subsequent steam treatment chamber, so that even a small amount of heat energy leaves these chambers 4 and 6 as energy loss. The yarn passage between the steam treatment chamber 5 and the subsequent chamber 6 is made relatively long, whereby a mechanical partitioning of the steam treatment chamber 5 is effected.

Die Kühlluft wird durch die vorzugsweise aus thermisch isolierendem Material bestehende Düse 13 direkt quer zum frei laufenden Faden in die Kühlkammer 6 eingeblasen. Diese Kühlluft trifft direkt auf den vorbeilaufenden Faden auf, was bei geringen Luftströmungen zu einem größtmöglichen Kühl- und auch Trocknungseffekt führt. Durch die Kühlluft werden Restdampfpartikel zwischen den Faserkapilaren des Fadens weitgehend aus dem Faden ausgetrieben, so dass der Faden getrocknet wird. Die Kühlluftströmung muss durch geeignete Auswahl des Düsenauslasses so eingestellt werden, dass ein Verwirbeln des Fadens vermieden wird.The cooling air is blown through the preferably made of thermally insulating material nozzle 13 directly across the free-running thread in the cooling chamber 6. This cooling air impinges directly on the passing thread, which at low air flows leads to the greatest possible cooling and drying effect. Due to the cooling air, residual vapor particles between the fiber capillaries of the thread are largely expelled from the thread, so that the thread is dried. The cooling air flow must be adjusted by suitable selection of the nozzle outlet so that a swirling of the thread is avoided.

Die anschließende Kühl- und Trocknungskammer 7, in die Kühlluft aus der Kammer 6 durch den diese beiden Kammern verbindende Fadenkanal eintritt, bewirkt ein weiteres Abkühlen und Trocknen. Der von dem Faden noch in diese Kühl- und Trocknungskammer 7 mitgerissene Restdampf wird im Bereich der glockenförmig nach oben gewölbten Böden 10 aus dem Faden ausgetrieben, wobei das Restkondensat durch den Kondensatauslass 7.2 und durch die Leitung 7.3 abgelassen wird.The subsequent cooling and drying chamber 7, enters the cooling air from the chamber 6 through the thread channel connecting these two chambers, causes further cooling and drying. The residual steam entrained by the thread still in this cooling and drying chamber 7 is expelled from the thread in the area of the bell-shaped upwardly curved bottoms 10, the residual condensate being discharged through the condensate outlet 7.2 and through the line 7.3.

Die Kühl- und Trockenkammer 7 ist mittels Rippen geometrisch so ausgeführt, dass eine maximale thermische Abschirmung erfolgt, d.h. diese Kühlkammer 7 wird in geringstmöglichem Umfang durch den von dem Faden mitgerissenen Restdampf erwärmt.The cooling and drying chamber 7 is geometrically designed by means of ribs so that a maximum thermal shielding takes place, ie this cooling chamber 7 is heated to the lowest possible extent by the entrained by the thread residual steam.

Das während des Aufwärmzyklus beim Einströmen des Dampfes in die Behandlungskammer 5 entstehende Kondensat wird in dem Kondensatbehälter 15 aufgefangen und nach Bedarf nach dem Erreichen der Betriebstemperatur TD in der Kammer 5 durch kurzes Öffnen des Ventils 16 abgelassen.The resulting during the warm-up cycle when the steam flows into the treatment chamber 5 condensate is collected in the condensate tank 15 and discharged as needed after reaching the operating temperature T D in the chamber 5 by briefly opening the valve 16.

Bei der Benutzung der Vorrichtung sind innerhalb der Behandlungsstrecke folgende Merkmale zu beachten:

  • spannungsloses Führen des Fadens
  • genaue Temperaturführung
  • exakte Länge des Fadenweges durch die Dampf- oder Gasbehandlungszone;
  • ausreichende und spontane Abkühlung des zum Zwecke der Thermofixierung mit Dampf behandelten Fadens, bevor der Faden wieder mechanisch belastet werden kann;
  • gleichmäßige Einwirkung von Temperatur, Geschwindigkeit und Abkühlung aller Behandlungsstrecken einer Vielstellenmaschine;
  • sichere und kostengünstige Ausführung des Systems;
  • sauberes Anlaufen und Ausscheiden der einzelnen Behandlungsstrecke unter Berücksichtigung der Kondensatableitung bei einer Dampfbehandlung.
When using the device, the following features must be observed within the treatment section:
  • tensionless guiding of the thread
  • accurate temperature control
  • exact length of the thread path through the steam or gas treatment zone;
  • sufficient and spontaneous cooling of the heat-setting treated with steam thread before the thread can be mechanically loaded again;
  • uniform effect of temperature, speed and cooling of all treatment lines of a multi-station machine;
  • safe and cost-effective implementation of the system;
  • clean start-up and elimination of the individual treatment section, taking into account the condensate drainage during a steam treatment.

Es handelt sich dabei um ein "Themofixiervorrichtung" , bei der der Dampfbehandlungskammer 5 Sattdampf mit einer Temperatur von ca. 135°C durch eine Dampfleitung 36 zugeführt wird, die an eine Dampf-Zentralleitung 33 angeschlossen ist, an die gemäß Figur 3 über Einzelanschlussleitungen 36a - 36x weitere Behandlungsstrecken angeschlossen sind.It is a "Themofixiervorrichtung", in which the steam treatment chamber 5 saturated steam is supplied at a temperature of about 135 ° C through a steam line 36 which is connected to a steam central line 33, according to FIG. 3 via individual connection lines 36a - 36x further treatment sections are connected.

In vergleichbarer Weise sind die Kammern 4 und 6 über Einzel-Anschlussleitungen 35 bzw. 37 an Zentralleitungen 32 bzw. 34 angeschlossen. An beide Zentralleitungen 32, 34 sind Einzel-Anschlussleitungen 35a - x bzw 37a - x angeschlossen. Die Druckluftleitungen 35 bzw. 37 sind mit Absperrventilen 4.4 bzw. 6.4 ausgerüstet, die Dampfleitung 36 enthält ein Absperrventil 5.4.In a comparable manner, the chambers 4 and 6 are connected via individual connection lines 35 and 37 to central lines 32 and 34, respectively. To both central lines 32, 34 single connection lines 35a - x or 37a - x are connected. The compressed air lines 35 and 37 are equipped with shut-off valves 4.4 and 6.4, the steam line 36 includes a shut-off valve 5.4.

Man lässt jeden Einzelfaden F im wesentlichen spannungsfrei durch die oben beschriebene Vorrichtung laufen.Each monofilament F is allowed to pass substantially stress-free through the device described above.

Zur Regelung der Dampftemperatur und der Drucklufttemperaturen dienen Dampftemperaturfühler TD im Bereich der Dampfbehandlungskammer 5 und Lufttemperaturfühler TK in einer der oberen Kammer 4 vorgeschalteten Vorkammer 3 und in der Kühl- und Trockenkammer 7. Die ermittelten Temperaturen sind die Regelgrößen für die an die Zentralleitungen 32, 33, 34 angeschlossenen Regelorgane (Zentralregler) 21a, 22 und 21b. Ein Block "Steuerung" ist über nicht dargestellte Leitungen an die Temperaturfühler TK und TD und an die Lieferwerke 11 und 12 angeschlossen. Bei Unter- oder Überschreiten vorgegebener Temperatur-Toleranzbereiche, insbesondere in den Kammern 3 und 7, wird die einzelne Fadenbehandlungsstrecke mittels der Ventile 4.4, 5.4 und 6.4 von den Zentralleitungen 32 abgeschaltet, wobei der Durchlauf des Fadens F durch die Vorrichtung durch Abschalten der Lieferwerke 11, 12 unterbrochen wird. Bei Auslaufen des Fadens oder bei Fadenbruch oder bei Ausfall eines Lieferwerks erfolgt ebenfalls über den Block "Steuerung" das Schließen der Ventile 4.4, 5.4 und 6.4, die mittels Steuerleitungen 4.6, 5.6 bzw. 6.6 an diesen Block angeschlossen sind. Während der Aufwärmphase wird die Dampfbehandlungskammer 5 auf die erforderliche Behandlungstemperatur erwärmt, wobei die Temperatur mittels der Dampftempcraturfühler TD gemessen wird. Während der Aufwärmphase werden die der Kammer 5 vor- und nachgeschalteten Kammern 4 und 6 derart mit Druckluft beaufschlagt, dass nach Aufbau einer bestimmten Luft-Dampf-Mischatmosphäre in diesen Kammern 4 und 6 im wesentlichen kein weiterer Dampf mehr aus der Kammer 5 in diese Kammern eintreten kann. Dabei ist es wesentlich, dass sich in den Kammern 4 und 6 bildenden Kondensat kontinuierlich abgeleitet wird, ebenso wie das sich in der Kammer 5 bildende Kondensat.To control the steam temperature and the compressed air temperatures serve steam temperature sensor T D in the steam treatment chamber 5 and air temperature sensor T K in an upper chamber 4 upstream antechamber 3 and in the cooling and drying chamber 7. The temperatures determined are the control variables for the to the central lines 32nd , 33, 34 connected control elements (central controller) 21a, 22 and 21b. A block "control" is connected via lines, not shown, to the temperature sensors T K and T D and to the delivery mechanisms 11 and 12. When falling below or exceeding predetermined temperature tolerance ranges, in particular in the chambers 3 and 7, the individual thread treatment section is switched off by the valves 4.4, 5.4 and 6.4 of the central lines 32, wherein the passage of the thread F by the device by switching off the delivery mechanisms 11th , 12 is interrupted. When the thread runs out, or if the thread breaks or a delivery system fails, the "Control" block also closes the valves 4.4, 5.4 and 6.4, which are connected to this block via control lines 4.6, 5.6 and 6.6. During the warm-up phase, the steam treatment chamber 5 is heated to the required treatment temperature, the temperature being measured by means of the steam temperature sensors T D. During the warming-up phase, the chambers 4 and 6 upstream and downstream of the chamber 5 are subjected to compressed air in such a way that, after a certain air-steam mixing atmosphere has been built up in these chambers 4 and 6, substantially no further vapor is released from the chamber 5 into these chambers can occur. It is essential that in the chambers 4 and 6 forming condensate is continuously discharged, as well as the forming in the chamber 5 condensate.

Die Regelung der jeweiligen Luft- und Dampfdrücke erfolgt zentral nach folgendem Modus:
Die Temperaturfühler TD in der Kammer 5 zeigen das Erreichen der erwünschten Behandlungtemperatur - z. B. ca. 135° als Sattdampftemperatur - an, die zuvor am Regelorgan (Zentralregler) 22 zentral eingestellt worden ist. Diese Temperatur bildet die Führungsgröße und muss innerhalb eines bestimmten Toleranzbereiches liegen. Eine Vergleichskontrolle erfolgt mittels eines Temperaturfühlers TL in der Dampfleitung 36.The control of the respective air and vapor pressures is done centrally according to the following mode:
The temperature sensor T D in the chamber 5 show the achievement of the desired treatment temperature -. B. about 135 ° as saturated steam temperature - to, previously at the control element (central controller) 22 has been set centrally. This temperature is the reference variable and must be within a certain tolerance range. A comparison check is carried out by means of a temperature sensor T L in the steam line 36.

Mittels des Temperaturfühlers TK in der Kammer 7 wird festgestellt, ob in dieser Kammer eine durch physikalische Effekte bedingte bestimmte Temperatur unterhalb der Dampftemperatur TD herrscht. Überschreitet die Temperatur in der Kammer 7 einen bestimmten Toleranzbereich, z. B. von ca. 50 - 70°C, muss der Luftdruck in der Kammer 7 zentral in kleinen Schritten entsprechend erhöht werden, wodurch der Kühleffekt stärker wird. Dabei darf die Temperatur TD nicht ansteigen.By means of the temperature sensor T K in the chamber 7 it is determined whether in this chamber due to physical effects certain temperature below the steam temperature T D prevails. If the temperature in the chamber 7 exceeds a certain tolerance range, for. B. of about 50 - 70 ° C, the air pressure in the chamber 7 must be increased centrally in small steps accordingly, whereby the cooling effect is stronger. The temperature T D must not rise.

Wird die Temperatur TD in der Behandlungskammer deutlich unterschritten, so liegt ein technischer Defekt vor, zum Beispiel bedingt durch Undichtigkeiten, so dass die einzelne Behandlungsstrecke stillgesetzt werden muss.If the temperature T D in the treatment chamber falls well below, then there is a technical defect, for example due to leaks, so that the individual treatment route must be shut down.

Wird die untere Temperaturgrenze von TK unterschritten, so wird der entsprechende Luftdruck in der Kühlzone zentral und feinstufig abgesenkt, so dass der Dampf in der Mischzone ein größeres Gewicht erhält und die Kühllufttemperatur in der Kammer 7 sich geringfügig erhöht.If the lower temperature limit of T K is exceeded, the corresponding air pressure in the cooling zone is lowered centrally and in a finely graduated manner so that the steam in the mixing zone receives a greater weight and the cooling air temperature in the chamber 7 increases slightly.

Der Kühlluftdruck in den Luftleitungen 35 und 37 und damit in den Kammern 4 und 6 muss unabhängig voneinander mittels der Regler 21 a bzw. 21 b geregelt werden, weil der durch die Kammer 5 laufende Faden das Dampfmedium mit sich reißt und damit die Temperaturzone in Fadenlaufrichtung verschiebt, was in der Kammer 6 zu von der Kammer 4 abweichenden Temperaturen führt.The cooling air pressure in the air lines 35 and 37 and thus in the chambers 4 and 6 must be controlled independently by means of the controller 21 a and 21 b, because the running through the chamber 5 thread tears the vapor medium and thus the temperature zone in the direction of yarn travel shifts, resulting in the chamber 6 to deviate from the chamber 4 temperatures.

Der Vorteil dieser Regelung besteht darin, dass bei großen zentralen Luft- und Dampfleitungen und demgegenüber kleinen Einzel-Anschlussleitungen 35, 36, 37 im Bereich der einzelnen Behandlungsstrecke nur ein einziger handelsüblicher Zentralregler 21a bzw. 21b bzw. 22 erforderlich ist. Die einzelnen Behandlungsstrecken haben damit einen sehr einfachen Aufbau.The advantage of this regulation is that, in the case of large central air and steam lines and, in contrast, small individual connection lines 35, 36, 37 in the region of the individual treatment section, only a single commercially available central controller 21a or 21b or 22 is required. The individual treatment sections thus have a very simple structure.
