Description

Die Erfindung betrifft eine Vorrichtung zum Spinnen von Fäden nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Heizen einer Vorrichtung zum Spinnen von Fäden nach dem Oberbegriff des Anspruchs 13.The invention relates to a device for spinning threads according to the preamble of claim 1 and a method for heating a device for spinning threads according to the preamble of claim 13.

Es sind Vorrichtungen zum Spinnen von Fäden bekannt, die zumindest eine Schmelzzuführeinrichtung und zumindest ein Düsenpaket mit zumindest einer Spinndüse zum Spinnen der Fäden aufweisen. Das Düsenpaket und somit die Spinndüse werden beheizt. Um gute Fadeneigenschaften zu erhalten, ist es wichtig, dass die Temperatur des Düsenpakets und die Temperaturverteilung innerhalb der Spinndüse in möglichst engen Grenzen gehalten wird. Es ist aus dem Stand der Technik gem. EP0828017 und WO2008/101863 bekannt, dass um das Düsenpaket ein erstes Gehäuse mit einer ersten Gehäusewand angeordnet ist. Um das erste Gehäuse kann ein zweites Gehäuse mit einer zweiten Gehäusewand angeordnet sein. Zwischen dem ersten und dem zweiten Gehäuse ist ein mit einem gasförmigen Heizmedium gefüllter Heizraum angeordnet, wobei die erste und die zweite Gehäusewand den Heizraum begrenzen. Auf diese Weise kann das Düsenpaket und somit die Spinndüse beheizt werden.Devices are known for spinning threads, which have at least one melt feed device and at least one nozzle package with at least one spinneret for spinning the threads. The nozzle package and thus the spinneret are heated. In order to obtain good thread properties, it is important that the temperature of the nozzle package and the temperature distribution within the spinneret are kept within the narrowest possible limits. It is according to the state of the art. EP0828017 and WO2008 / 101863 It is known that a first housing with a first housing wall is arranged around the nozzle package. A second housing with a second housing wall can be arranged around the first housing. Between the first and the second housing a filled with a gaseous heating medium heating chamber is arranged, wherein the first and the second housing wall define the boiler room. In this way, the nozzle package and thus the spinneret can be heated.

Aus der DE 102007021433 ist eine weitere Schmelzspinnvorrichtung zum Schmelzspinnen synthetischer Filamente mit mehreren im Wesentlichen kreisförmig um ein Zentrum angeordneten Spinnpaketen. Die mittels eines Wärmeträgermediums beheizte Schmelzspinnvorrichtung weist eine Vertiefung auf, in der sich kondensiertes Wärmeträgermedium sammelt und mittels einer Heizung wieder verdampft wird.From the DE 102007021433 is another melt spinning apparatus for melt spinning synthetic filaments having a plurality of spin packs substantially circular about a center. The melt spinning device heated by means of a heat transfer medium has a depression in which condensed heat transfer medium collects and is vaporized again by means of a heater.

Aus der WO95/07378 ist ein Spinnbalken zum Schmelzspinnen von Filamenten bekannt, wobei die Wärmeübertragung vom Heizkasten eines Spinnbalkens auf das darin getragene Düsenpaket wird dadurch verbessert, dass die Halterung für das Paket mit Wärmeaufnahmeelementen versehen ist. Diese Elemente sind in Betrieb Sattdampf ausgesetzt und sind mit Kondensationsflocken versehen, um Wärme vom Sattdampf aufzunehmen. Die aufgenommene Wärme wird über mindestens eine Wärmebrücke an das Paket übertragen.From the WO95 / 07378 For example, a spinneret for melt-spinning filaments is known in which the heat transfer from the heating box of a spinner to the nozzle package carried therein is improved by providing the package support with heat-absorbing elements. These elements are exposed to saturated steam during operation and are provided with condensation flocks to absorb heat from the saturated steam. The heat absorbed is transferred to the package via at least one thermal bridge.

Ein weiterer Spinnbalken ist aus der EP0163248 bekannt, bei dem der Heizmantel des Spinnbalkens in einem Gehäuse untergebracht und von einer Wärmeisolierung umgeben ist.Another spinning beam is out of the EP0163248 known, in which the heating jacket of the spinner is housed in a housing and surrounded by a thermal insulation.

Innerhalb des Heizraumes kommt es zur Kondensatbildung des gasförmigen Heizmediums. Wenn zu viel Kondensat im Heizraum vorhanden ist, kann es zu einer ungleichmäßigen Temperaturverteilung kommen.Within the boiler room, condensation of the gaseous heating medium occurs. If there is too much condensate in the boiler room, the temperature distribution may be uneven.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zu schaffen, bei der bzw. bei dem das Düsenpaket und somit die Spinndüse gleichmäßig beheizt werden kann.The present invention is therefore based on the object to provide an apparatus and a method in which or in which the nozzle package and thus the spinneret can be heated uniformly.

Zur Lösung dieser Aufgabe dienen die Merkmale der Ansprüche 1 und 13.To achieve this object, the features of claims 1 and 13 serve.

Die Erfindung sieht in vorteilhafter Weise vor, dass der Heizraum durch einen Gehäuseboden begrenzt ist, der von der ersten Gehäusewand in Richtung der zweiten Gehäusewand schräg abfallend ausgebildet ist, so dass am Gehäuseboden angesammeltes Kondensat in Richtung der zweiten Gehäusewand abläuft.The invention advantageously provides that the heating space is delimited by a housing bottom, which is formed sloping obliquely from the first housing wall in the direction of the second housing wall, so that condensate accumulated on the housing bottom expires in the direction of the second housing wall.

Dies hat den Vorteil, dass das Kondensat sich nicht im Bereich der ersten Gehäusewand ansammelt, wo es dazu führen kann, dass die Temperatur des Düsenpakets nachteilig beeinflusst wird.This has the advantage that the condensate does not accumulate in the region of the first housing wall, where it can lead to the temperature of the nozzle package being adversely affected.

Die erste Gehäusewand kann über ein den Gehäuseboden aufweisendes Bodenelement mit der zweiten Gehäusewand verbunden sein.The first housing wall can be connected to the second housing wall via a floor element having the housing bottom.

Es kann eine Auslassöffnung in der zweiten Gehäusewand vorgesehen sein, an der eine Kondensatabführleitung angeschlossen ist, wobei das in dem Heizraum anfallende und am Gehäuseboden angesammelte Kondensat aufgrund der Kontur des Gehäusebodens zu der Auslassöffnung leitbar ist.An outlet opening can be provided in the second housing wall, to which a condensate discharge line is connected, wherein the condensate accumulating in the heating space and accumulated on the housing bottom can be conducted to the outlet opening due to the contour of the housing bottom.

Dies hat den Vorteil, dass das Kondensat besonders effektiv abgeführt werden kann und es nicht zu einer Ansammlung des Kondensats im Heizraum kommt. Dies trägt wiederum zu einer Vergleichmäßigung der Temperatur im Düsenpaket bei.This has the advantage that the condensate can be removed particularly effectively and there is no accumulation of condensate in the boiler room. This in turn contributes to a homogenization of the temperature in the nozzle package.

Die Auslassöffnung kann derart angeordnet sein, dass zumindest ein Teil der Auslassöffnung tiefer ist als die tiefste Stelle des Gehäusebodens. Auf diese Weise kann das Kondensat besonders effektiv und schnell abgeführt werden.The outlet opening may be arranged such that at least a part of the outlet opening is deeper than the lowest point of the housing bottom. In this way, the condensate can be removed particularly effectively and quickly.

Zumindest die tiefste Stelle des Gehäusebodens nahe der zweiten Gehäusewand kann tiefer angeordnet sein als der Boden des in dem ersten Gehäuse angeordneten Düsenpakets.At least the lowest point of the housing bottom near the second housing wall can be arranged lower than the bottom of the nozzle package arranged in the first housing.

Dies bedeutet, dass das gesamte Düsenpaket effektiv beheizt werden kann, da es in dem Bereich der Beheizung nicht zu einer Ansammlung des Kondensats kommt.This means that the entire nozzle package can be heated effectively, since there is no accumulation of condensate in the area of heating.

Auch die höchste Stelle des Gehäusebodens nahe der ersten Gehäusewand kann tiefer angeordnet sein als der Boden des in dem ersten Gehäuse angeordneten Düsenpakets.Also, the highest point of the housing bottom near the first housing wall can be arranged lower than the bottom of the nozzle package arranged in the first housing.

Das erste und das zweite Gehäuse können zylinderförmig, insbesondere kreiszylinderförmig, ausgebildet sein. Dies bedeutet, dass der Wärmeverlust nach außen hin besonders gering ist. Auf diese Weise kann Energie zum Heizen eingespart werden. Ferner ist es einfacher die Temperatur konstant zu halten.The first and the second housing may be cylindrical, in particular circular cylindrical, formed. This means that the heat loss to the outside is particularly low. In this way energy can be saved for heating. Furthermore, it is easier to keep the temperature constant.

Das von dem Heizraum umgebene erste Gehäuse weist einen Gehäusedeckel auf, der eine umlaufende Nut aufweist.The first housing surrounded by the heating chamber has a housing cover, which has a circumferential groove.

Dies hat den Vorteil, dass die Wärmeübertragungsfläche vergrößert wird. Auf diese Weise wird auch die Beheizung des oberen Teils des ersten Gehäuses verbessert.This has the advantage that the heat transfer surface is increased. In this way, the heating of the upper part of the first housing is improved.

Die Schmelzzuführeinrichtung kann eine Dosiereinrichtung aufweisen, wobei die Dosiereinrichtung innerhalb des Heizraums angeordnet ist. Die Dosiereinrichtung ist vorzugsweise oberhalb des ersten Gehäuses angeordnet.The melt supply device can have a metering device, wherein the metering device is arranged within the heating chamber. The metering device is preferably arranged above the first housing.

Das gasförmige Heizmedium kann über eine Heizzuführleitung dem Heizraum zuführbar sein.The gaseous heating medium can be fed to the boiler room via a Heizzuführleitung.

Innerhalb der Heizzuführleitung kann eine Schmelzzuführleitung angeordnet sein, die die Schmelze zu der Dosiereinrichtung führt.Within the Heizzuführleitung a Schmelzzuführleitung may be arranged, which leads the melt to the metering device.

Dies hat den Vorteil, dass auch die Schmelzzuführleitung beheizt ist.This has the advantage that the melt supply line is heated.

Die Heizzuführleitung kann eine zweite Kondensatabführleitung aufweisen. Auf diese Weise wird verhindert, dass das Kondensat, das sich in der Heizzuführleitung bildet, in den Heizraum eingeführt wird.The Heizzuführleitung may have a second Kondensatabführleitung. In this way it is prevented that the condensate that forms in the Heizzuführleitung is introduced into the boiler room.

Die zweite Kondensatabführleitung kann nahe des Eintritts der ersten Heizzuführleitung in den Heizraum angeordnet sein.The second Kondensatabführleitung may be arranged near the entrance of the first Heizzuführleitung in the boiler room.

Das erste Gehäuse kann nach unten offen sein, so dass das Düsenpaket in das erste Gehäuse einführbar ist.The first housing may be downwardly open so that the nozzle package is insertable into the first housing.

Die Erfindung sieht ferner ein Verfahren zum Heizen einer Vorrichtung zum Spinnen von Fäden vor, das die folgenden Schritte aufweist:

  • Einführen eines Heizmediums in einen durch mindestens eine erste und eine zweite Gehäusewand und einen Gehäuseboden begrenzten Heizraum,
  • wobei innerhalb des Heizraums eine zu beheizende Dosiereinrichtung und ein zu beheizendes Düsenpaket mit mindestens einer Spinndüse angeordnet sind.
The invention further provides a method for heating a device for spinning threads, comprising the following steps:
  • Introducing a heating medium into a heating space bounded by at least a first and a second housing wall and a housing bottom,
  • wherein a metering device to be heated and a nozzle package to be heated with at least one spinneret are arranged within the heating chamber.

Es wird in vorteilhafter Weise vorgesehen, dass in dem Heizraum anfallendes Kondensat in dem Bereich des Gehäusebodens abgeführt wird.It is advantageously provided that condensate accumulating in the heating space is removed in the region of the housing bottom.

Aufgrund der Kontur des Gehäusebodens kann das Kondensat in die Kondensatabführleitung geleitet werden.Due to the contour of the housing bottom, the condensate can be directed into the Kondensatabführleitung.

Dies hat den Vorteil, dass das Kondensat besonders effektiv abgeführt werden kann.This has the advantage that the condensate can be removed particularly effectively.

Das Düsenpaket 4 mit zumindest einer Spinndüse ist in einem ersten Gehäuse 8 angeordnet. Das Düsenpaket 4 ist jedoch nur schematisch dargestellt. Es ist lediglich die äußere Begrenzung des Düsenpakets dargestellt, um zu verdeutlichen, wo das Düsenpaket 4 angeordnet ist. Um das erste Gehäuse 8 ist ein zweites Gehäuse 10 angeordnet, wobei zwischen dem ersten und dem zweiten Gehäuse 8, 10 ein mit einem gasförmigen Heizmedium gefüllter Heizraum 14 angeordnet ist.In Fig. 2 a part of the device 1 for spinning threads is shown in more detail. The melting device 2 is not shown and also the injection shaft 27 is not shown. The nozzle package 4 with at least one spinneret is arranged in a first housing 8.

Das dem oberen Ende entgegengesetzte untere Ende der ersten Gehäusewand 3 ist mit dem dem oberen Ende entgegengesetzten unteren Ende der zweiten Gehäusewand 6 über ein einen Gehäuseboden 28 aufweisendes Bodenelement 25 verbunden. Der Gehäuseboden 28 ist der Gehäuseboden 28 des Heizraums 14 und begrenzt diesen nach unten. Der Gehäuseboden 28 ist die dem Heizraum 14 zugewandte Seite des Bodenelements 25. Das erste Gehäuse 8 ist nach unten hin offen, damit das Düsenpaket 4 in das erste Gehäuse einführbar ist. An dem Bodenelement 25 kann eine nicht dargestellte Anschlusseinrichtung für den nicht dargestellten Anblasschacht 27 befestigt werden.The second housing 10 has a second housing wall 6 and a housing cover 29 arranged at the upper end of the second housing wall 6. The first housing 8 arranged in the second housing 10 has a first housing wall 3 and a housing cover 16 arranged at the upper end of the first housing wall 3.

Die Schmelzzuführleitung 20 ist außerhalb des Heizraums 14 in einer Heizzuführleitung 22 angeordnet. Auf diese Weise wird die Schmelzzuführleitung 20 beheizt. Die Heizzuführleitung 22 führt das gasförmige Heizmedium dem Heizraum 14 zu.The melt is now guided by the melting device 2 via the melt supply line 20 to the metering device 12.

An der Schmelzzuführleitung 20 ist eine Schmelzhalteeinrichtung 24 angeordnet, die durch Druckaufbau den Querschnitt der Schmelzzuführleitung 20 verringern kann und somit die Zuführung der Schmelze zu der Dosiereinrichtung 12 zumindest vorübergehend unterbrechen kann.At the melt supply line 20, a melt holding device 24 is arranged, which can reduce the cross section of the melt supply line 20 by pressure build-up and thus can interrupt the supply of the melt to the metering device 12 at least temporarily.

Das erste Gehäuse 8 und/oder das zweite Gehäuse 10 sind vorzugsweise kreiszylinderförmig ausgeführt. Dies hat den Vorteil, dass es zu geringeren Wärmeverlusten kommt. Auf diese Weise kann Energie eingespart werden. Das erste Gehäuse 8 und/oder das zweite Gehäuse 10 können alternativ auch eine andere Form aufweisen. Sie können beispielsweise auch quaderförmig ausgebildet sein. In diesem Fall würde das erste Gehäuse vier erste Gehäusewände aufweisen und das zweite Gehäuse würde vier zweite Gehäusewände aufweisen.The first housing 8 and / or the second housing 10 are preferably circular cylindrical. This has the advantage that it comes to lower heat losses. In this way energy can be saved. The first housing 8 and / or the second housing 10 may alternatively have a different shape. They can for example also be cuboid. In this case, the first housing would have four first housing walls and the second housing would have four second housing walls.

In Fig. 2 ist ferner eine Hülse 70 für den Anschluss eines Temperaturfühlers dagestellt.In Fig. 2 Furthermore, a sleeve 70 for the connection of a temperature sensor is dagestellt.

Der Gehäuseboden 28, der in Fig. 3 im Detail dargestellt ist, ist von der ersten Gehäusewand in Richtung der zweiten Gehäusewand 6 schräg abfallend ausgebildet, so dass ein am Gehäuseboden 28 angesammeltes Kondensat in Richtung der zweiten Gehäusewand 6 abläuft. Das Kondensat, das sich im Heizraum 14 bildet, sammelt sich am Gehäuseboden 28 an. Aufgrund der Kontur des Gehäusebodens 28 läuft das Kondensat jedoch Richtung zweite Gehäusewand 6 ab. Auf diese Weise sammelt sich das Kondensat nicht an der ersten Gehäusewand 3 an. Dies hat den Vorteil, dass die Temperatur insbesondere in dem Düsenpaket 4 konstant gehalten werden kann.The housing bottom 28, the in Fig. 3 is shown in detail, is formed sloping from the first housing wall in the direction of the second housing wall 6, so that a condensate accumulated on the housing bottom 28 in the direction of the second housing wall 6 expires. The condensate that forms in the heating chamber 14 accumulates at the housing bottom 28. Due to the contour of the housing bottom 28, the condensate, however, runs in the direction of the second housing wall 6. In this way, the condensate does not accumulate on the first housing wall 3. This has the advantage that the temperature can be kept constant, in particular in the nozzle package 4.

An der zweiten Gehäusewand 6 ist eine Auslassöffnung 32 angeordnet. An diese Auslassöffnung 32 ist eine Kondensatabführleitung 30 angeschlossen. Das in dem Heizraum anfallende und am Gehäuseboden angesammelte Kondensat kann aufgrund der Kontur des Gehäusebodens 28 zu der Auslassöffnung 32 geleitet werden und dort durch die Kondensatabführleitung 30 abgeführt werden.On the second housing wall 6, an outlet opening 32 is arranged. At this outlet opening 32 a Kondensatabführleitung 30 is connected. The accumulated in the boiler room and accumulated at the bottom of the housing condensate can be passed to the outlet opening 32 due to the contour of the housing bottom 28 and discharged there through the Kondensatabführleitung 30.

Wie auch Fig. 3 zu entnehmen ist, ist die Kondensatabführleitung 30 vorzugsweise derart angeordnet, dass zumindest ein Teil der Kondensatabführleitung 30 tiefer ist als die tiefste Stelle 40 des Gehäusebodens 28.As well as Fig. 3 it can be seen, the Kondensatabführleitung 30 is preferably arranged such that at least a portion of the Kondensatabführleitung 30 is deeper than the lowest point 40 of the housing bottom 28th

Es sei noch erwähnt, dass in der vorliegenden Anmeldung unten und oben derart verstanden wird, dass der Gehäusedeckel 16 des ersten Gehäuses 8 und der Gehäusedeckel 29 des zweiten Gehäuses 10 oben angeordnet ist und das Bodenelement 25 mit dem Gehäuseboden 28 unten angeordnet ist. Tiefer bedeutet in der vorliegenden Erfindung, dass etwas weiter unten angeordnet ist. Außerdem läuft das Kondensat aufgrund der Erdanziehungskraft stets nach unten.It should be noted that in the present application is understood below and above such that the housing cover 16 of the first housing 8 and the housing cover 29 of the second housing 10 is disposed at the top and the bottom member 25 is arranged with the housing bottom 28 below. Lower means in the present invention that is located slightly lower. In addition, the condensate always runs down due to the gravitational force.

Wie aus Fig. 3 zu entnehmen ist, ist die tiefste Stelle 40 des Gehäusebodens 28 nahe der zweiten Gehäusewand 6 angeordnet. Die tiefste Stelle 40 des Gehäusebodens 28 ist tiefer angeordnet als der Boden 42 des in dem ersten Gehäuse 8 angeordneten Düsenpakets 4. Dies hat den Vorteil, dass das Kondensat sich nicht in dem Bereich ansammelt, in dem das Düsenpaket 4 angeordnet ist. Somit kann das Düsenpaket 4 gleichmäßig beheizt werden. Auch in Fign. 3 und 4 ist das Düsenpaket 4 nur schematisch dargestellt. Es ist lediglich die äußere Begrenzung des Düsenpakets dargestellt, um zu verdeutlichen, wo das Düsenpaket 4 angeordnet ist.How out Fig. 3 can be seen, the lowest point 40 of the housing bottom 28 is disposed near the second housing wall 6. The lowest point 40 of the housing bottom 28 is arranged lower than the bottom 42 of the nozzle package 4 arranged in the first housing 8. This has the advantage that the condensate does not accumulate in the region in which the nozzle package 4 is arranged. Thus, the nozzle package 4 can be heated evenly. Also in FIGS. 3 and 4 the nozzle package 4 is shown only schematically. Only the outer boundary of the nozzle package is shown in order to illustrate where the nozzle package 4 is arranged.

In Fig. 2 ist ferner eine zweite Kondensatabführleitung 44 dargestellt. Die zweite Kondensatabführleitung 44 ist mit der Heizzufuhrleitung 22 verbunden. Die zweite Kondensatabführleitung 44 kann nahe dem Eintritt der Heizzufuhrleitung 22 in dem Heizraum 14 mit der Heizzuführleitung 22 verbunden sein. Mittels dieser zweiten Kondensatabführleitung 44 kann das in der Heizzuführleitung 22 angesammelte Kondensat abgeführt werden. Auf diese Weise wird das Kondensat, das sich bereits in der Heizzuführleitung 22 bildet, nicht in den Heizraum 14 eingeleitet. Somit ist sichergestellt, dass das Kondensat, das sich in der Heizzuführleitung bildet vor Einführung in den Heizraum 14 abgeführt wird.In Fig. 2 Furthermore, a second Kondensatabführleitung 44 is shown. The second Kondensatabführleitung 44 is connected to the Heizzufuhrleitung 22. The second Kondensatabführleitung 44 may be connected near the entrance of the Heizzufuhrleitung 22 in the heating chamber 14 with the Heizzuführleitung 22. By means of this second Kondensatabführleitung 44, the accumulated in the Heizzuführleitung 22 condensate can be removed. In this way, the condensate that already forms in the Heizzuführleitung 22, not introduced into the heating chamber 14. This ensures that the condensate which forms in the Heizzuführleitung is discharged before introduction into the heating chamber 14.

In Fig. 4 ist der Gehäusedeckel 16 des ersten Gehäuses 8 näher dargestellt. Der Gehäusedeckel 16 weist eine umlaufende Nut 18 auf. Durch die umlaufende Nut 18 wird die Wärmeübertragungsfläche erhöht und somit die Beheizung des ersten Gehäuses insbesondere in dem Bereich des Gehäusedeckels 16 verbessert.In Fig. 4 the housing cover 16 of the first housing 8 is shown in more detail. The housing cover 16 has a circumferential groove 18. By the circumferential groove 18, the heat transfer surface is increased and thus improves the heating of the first housing, in particular in the region of the housing cover 16.
