Definitions
- the invention relates to a device for spinning man-made fibers according to the preamble of claim 1.
- This spinning device is known from DE-A 19 14 556.
- it has the advantage that the fiber bundle, which consists of a large number of individual filaments, is subjected to an air flow over its entire circumference.
- uneven thread properties arise. This unevenness may be due to the fact that the chemical fibers running at very high speed and at the same time very high thread tension only become uniform over their length if the running smoothness is very great.
- air turbulence in the spinning chamber which leads to pressure fluctuations on the outer jacket of the cooling tube, also results in an uneveness of the filaments or threads produced. This is especially true when the spinning device is operated at a very high winding speed. Because this creates very strong air movements.
- EP 0 117 215 B1 and EP 0 118 375 B1 disclose spinning devices whose winding machine, with which the chemical fibers are wound into bobbins, are arranged at a short distance below the spinneret. This is made possible by the fact that Chemical fibers at a very high speed of more than 6000 m / min. be wound up. This results in a very intensive cooling of the threads, so that a very short cooling zone of about 2 m is sufficient, while cooling zones of more than 4 m are required in conventional spinning systems. As a result of the high speed, there is very strong air friction, so that the chemical fibers are wound up more or less completely stretched.
- the man-made fibers can be drawn off from the spinneret directly by pulling the take-up spool.
- a delivery mechanism can also be provided between the spinneret and the winding device, in particular a slip conveyor mechanism according to DE-A 41 35 350 (1-1951).
- porous or perforated cooling tubes have hitherto been used, which are the subject of DE-A 34 06 347 (Bag. 1326) and DE-A 34 24 253.8-26 (Bag. 1419) ) are. Reference can also be made to DE-A 37 41 135 (Bag. 1558) and DE-A 39 23 067 (Bag. 1648).
- the cooling air is supplied in a defined manner by a blower, so that the air flow supplied to the cooling pipe can be largely homogenized in terms of space and time.
- a disadvantage of this latter blowing technology is that complex apparatus and procedural measures are required in order to ensure a temporal and very uniform length, i.e. to achieve swirl-free air flow on the chemical fiber bundle.
- the object of the invention is to design the known spinning device so that a simple the chemical fibers run smoothly and chemical fibers with great longitudinal uniformity are produced.
- the radial air flow is generated in that the chemical fibers running at high speed create a negative pressure in the tube.
- the invention enables good flow and cooling conditions to be set with little effort.
- the measure according to claim 3 is also used. These measures not only prevent the air vortices entrained by the fiber bundle from flowing back into the area of the cooling tube and leading to an uneven application of atmospheric air to the cooling tube. It will rather, it also prevents pressure fluctuations and pressure waves from propagating into the intake area of the cooling tube.
- the proposed air box is connected to the atmosphere.
- the air box is designed so that there is essentially atmospheric pressure or vacuum.
- defined openings can be provided at one or more points.
- An intermediate wall can be used to prevent the inflowing air from acting directly on the outer circumference of the cooling tube.
- the air box can be penetrated by a plurality of cooling tubes, each of which is assigned to a spinneret. This makes it possible to produce the same cooling conditions for the majority of the cooling tubes and in this way to one another to produce the same and uniform chemical fibers.
- the air box is not connected to a blower with which an air pressure, albeit low, is generated in the air box. Rather, the fact that a pressure gradient arises which is directed from the spinning chamber into the air box and from there into the cooling tube is used for the air supply.
- Measures can be provided to direct the air currents drawn into the cooling tube from the outside in. This can be done in particular by guide rings which are attached to the inner wall of the cooling tube in one or more normal planes and are directed essentially radially inwards. Of course, these guide rings leave a passage opening for the chemical fiber bundle in the center of the cooling tube.
- a vacuum is also created on the underside of the guide rings, which leads to pre-suction of the outside air.
- the filaments are initially in the open state, ie. H. in front of the thread guide 7, are passed through a cooling tube 5.
- the cooling tube 5 connects directly to the spinneret 3.
- the cooling tube 5 is porous. It has a length of 0.5 to 2.0 meters.
- a shielding plate 6 is applied at the outlet end of the cooling tube 5.
- the shielding plate 6 has a passage opening for the filament bundle, the width of which is equal to or less than the inside width of the cooling tube 5.
- the porosity of the cooling tube 5 increases in the direction of the thread.
- the porosity is essentially proportional, but at least depends on the thread running speed.
- the porosity can also be adapted to the temperature profile that the filaments have over their length. In both of the cases described, the porosity increases in the thread running direction, ie the air permeability increases.
- the embodiment of Figure 1 has the peculiarity that a plurality of baffle plates 17 are arranged in the cooling tube.
- the baffle plates 17 are annular plates. These annular sheets are fastened with their outer circumference to the cooling tube 5 and point with their inner edge in the thread running direction, that is to say they are inclined downwards. These baffle plates 17 guide the sucked-in air currents downward, but also cause a negative pressure to develop beneath them, so that this results in a suction effect.
- the thread speed is more than 6000 m / min.
Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Spinnen von Chemiefasern nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for spinning man-made fibers according to the preamble of claim 1.
Diese Spinnvorrichtung ist bekannt durch die DE-A 19 14 556. Bei dieser Ausführung hat man zwar einerseits den Vorteil, daß das Faserbündel, das aus einer Vielzahl von einzelnen Filamenten besteht, auf seinem ganzen Umfang mit einer Luftströmung beaufschlagt wird. Es hat sich jedoch herausgestellt, daß ungleichmäßige Fadeneigenschaften entstehen. Diese Ungleichmäßigkeit dürfte darauf zurückzuführen sein, daß die mit sehr hoher Geschwindigkeit und gleichzeitig sehr hoher Fadenspannung laufenden Chemiefasern nur bei sehr großer Laufruhe über ihre Länge gleichmäßig werden. Weiter ergibt sich als Nachteil, daß Luftturbulenzen des Spinnraumes, die zu Druckschwankungen auf dem Außenmantel des Kühlrohres führen, auch eine Ungleichmäßigkeit der erzeugten Filamente bzw. Fäden zur Folge haben. Das gilt insbesondere dann, wenn die Spinnvorrichtung mit sehr hoher Aufspulgeschwindigkeit betrieben wird. Denn dadurch entstehen zum einen sehr starke Luftbewegungen. Zum anderen ist lediglich eine sehr kurze Kühlzone erforderlich, so daß Druckschwankungen der als Kühlluft angesaugten atmosphärischen Luft mit entsprechender Verstärkung zu Qualitätsschwankungen des Fadens führen. So sind z.B. durch die EP 0 117 215 B1 und EP 0 118 375 B1 Spinnvorrichtungen bekannt, deren Aufwickelmaschine, mit welcher die Chemiefasern zu Spulen aufgespult werden, in geringem Abstand unter der Spinndüse angeordnet sind. Das wird dadurch ermöglicht, daß die Chemiefasern mit sehr hoher Geschwindigkeit von mehr als 6000 m/min. aufgewickelt werden. Dadurch ergibt sich zwar eine sehr intensive Kühlung der Fäden, so daß man mit einer sehr kurzen Kühlzone von ca. 2 m auskommt, während in konventionellen Spinnanlagen Kühlzonen von mehr als 4 m erforderlich sind. Infolge der hohen Geschwindigkeit ergibt sich eine sehr starke Luftreibung, so daß die Chemiefasern mehr oder weniger vollständig verstreckt aufgespult werden.This spinning device is known from DE-A 19 14 556. In this embodiment, on the one hand, it has the advantage that the fiber bundle, which consists of a large number of individual filaments, is subjected to an air flow over its entire circumference. However, it has been found that uneven thread properties arise. This unevenness may be due to the fact that the chemical fibers running at very high speed and at the same time very high thread tension only become uniform over their length if the running smoothness is very great. Another disadvantage is that air turbulence in the spinning chamber, which leads to pressure fluctuations on the outer jacket of the cooling tube, also results in an uneveness of the filaments or threads produced. This is especially true when the spinning device is operated at a very high winding speed. Because this creates very strong air movements. On the other hand, only a very short cooling zone is required, so that pressure fluctuations in the atmospheric air drawn in as cooling air, with corresponding reinforcement, lead to fluctuations in the quality of the thread. For example, EP 0 117 215 B1 and EP 0 118 375 B1 disclose spinning devices whose winding machine, with which the chemical fibers are wound into bobbins, are arranged at a short distance below the spinneret. This is made possible by the fact that Chemical fibers at a very high speed of more than 6000 m / min. be wound up. This results in a very intensive cooling of the threads, so that a very short cooling zone of about 2 m is sufficient, while cooling zones of more than 4 m are required in conventional spinning systems. As a result of the high speed, there is very strong air friction, so that the chemical fibers are wound up more or less completely stretched.
Die Chemiefasern können unmittelbar durch Zugkraft der Aufwickelspule von der Spinndüse abgezogen werden. Es kann jedoch auch zwischen die Spinndüse und Aufspuleinrichtung ein Lieferwerk vorgesehen sein, insbesondere ein Schlupflieferwerk nach der DE-A 41 35 350 (1-1951).The man-made fibers can be drawn off from the spinneret directly by pulling the take-up spool. However, a delivery mechanism can also be provided between the spinneret and the winding device, in particular a slip conveyor mechanism according to DE-A 41 35 350 (1-1951).
Man hat zur Vermeidung von Qualitätsschwankungen bei der Abkühlung der Fäden unterhalb der Spinndüsen bisher poröse oder perforierte Kühlrohre verwandt, die beispielsweise Gegenstand der DE-A 34 06 347 (Bag. 1326) und der DE-A 34 24 253.8-26 (Bag. 1419) sind. Ebenso kann auf die DE-A 37 41 135 (Bag. 1558) sowie die DE-A 39 23 067 (Bag. 1648) Bezug genommen werden. Hierbei wird die Kühlluft jedoch definiert durch ein Gebläse zugeführt, so daß eine weitgehende Vergleichmäßigung des dem Kühlrohr zugeführten Luftstromes in räumlicher und zeitlicher Hinsicht möglich ist. Nachteilig ist bei dieser letztgenannten Anblastechnologie, daß aufwendige apparative und verfahrensmäßige Maßnahmen erforderlich sind, um eine zeitliche und über die Länge sehr gleichmäßigen, d.h. wirbelfreien Luftstrom auf das Chemiefaserbündel zu erzielen.In order to avoid quality fluctuations in the cooling of the threads below the spinnerets, porous or perforated cooling tubes have hitherto been used, which are the subject of DE-A 34 06 347 (Bag. 1326) and DE-A 34 24 253.8-26 (Bag. 1419) ) are. Reference can also be made to DE-A 37 41 135 (Bag. 1558) and DE-A 39 23 067 (Bag. 1648). Here, however, the cooling air is supplied in a defined manner by a blower, so that the air flow supplied to the cooling pipe can be largely homogenized in terms of space and time. A disadvantage of this latter blowing technology is that complex apparatus and procedural measures are required in order to ensure a temporal and very uniform length, i.e. to achieve swirl-free air flow on the chemical fiber bundle.
Die Aufgabe der Erfindung besteht darin, die bekannte Spinnvorrichtung so auszugestalten, daß mit einfachen Mitteln eine gute Laufruhe der Chemiefasern erzielt und Chemiefasern großer Längs-Gleichmäßigkeit erzeugt werden.The object of the invention is to design the known spinning device so that a simple the chemical fibers run smoothly and chemical fibers with great longitudinal uniformity are produced.
Die Lösung ergibt sich aus dem Kennzeichen des Anspruches 1.The solution results from the characterizing part of claim 1.
Bei der bekannten Vorrichtung wird der radiale Luftstrom dadurch erzeugt, daß die mit hoher Geschwindigkeit laufenden Chemiefasern einen Unterdruck in dem Rohr erzeugen. Die Erfindung ermöglicht demgegenüber die Einstellung guter Strömungs- und Kühlungsverhältnisse mit geringem Aufwand.In the known device, the radial air flow is generated in that the chemical fibers running at high speed create a negative pressure in the tube. In contrast, the invention enables good flow and cooling conditions to be set with little effort.
Zur Gewährleistung gleichmäßiger Strömungsverhältnisse in dem Kühlrohr dient zusätzlich die Maßnahme nach Anspruch 3. Durch diese Maßnahmen wird nicht nur verhindert, daß die von dem Faserbündel mitgeschleppten Luftwirbel zurückströmen in den Bereich des Kühlrohres und zu einer ungleichmäßigen Beaufschlagung des Kühlrohrs mit atmosphärischer Luft führen.Es wird vielmehr auch verhindert, daß Druckschwankungen und Druckwellen sich in den Einzugsbereich des Kühlrohres fortpflanzen.To ensure uniform flow conditions in the cooling tube, the measure according to
Der vorgeschlagene Luftkasten ist mit der Atmosphäre verbunden. Man kann sich auch den Anschluß an ein vorgekühltes Medium vorstellen. Jedenfalls ist der Luftkasten so ausgestaltet, daß in ihm im wesentlichen atmosphärischer Druck oder Unterdruck herrscht. Hierzu können an einer oder mehreren Stellen definierte Öffnungen vorgesehen sein. Durch eine Zwischenwand kann verhindert werden, daß die einströmende Luft unmittelbar den Außenumfang des Kühlrohres beaufschlagt. Der Luftkasten kann von einer Mehrzahl von Kühlrohren, die jeweils einer Spinndüse zugeordnet sind, durchdrungen werden. Hierdurch gelingt es, führ die Mehrzahl der Kühlrohre gleiche Kühlbedingungen herzustellen und auf diese Weise untereinander gleiche und gleichmäßige Chemiefasern zu erzeugen. Es sei noch einmal hervorgehoben, daß in allen diesen Fällen der Luftkasten nicht an ein Gebläse angeschlossen wird, mit dem in dem Luftkasten ein - wenn auch geringer - Luftüberdruck erzeugt wird. Vielmehr wird zur Luftzufuhr die Tatsache genutzt, daß ein Druckgradient entsteht, der aus dem Spinnraum in den Luftkasten und von dort in das Kühlrohr gerichtet ist.The proposed air box is connected to the atmosphere. One can also imagine the connection to a pre-cooled medium. In any case, the air box is designed so that there is essentially atmospheric pressure or vacuum. For this purpose, defined openings can be provided at one or more points. An intermediate wall can be used to prevent the inflowing air from acting directly on the outer circumference of the cooling tube. The air box can be penetrated by a plurality of cooling tubes, each of which is assigned to a spinneret. This makes it possible to produce the same cooling conditions for the majority of the cooling tubes and in this way to one another to produce the same and uniform chemical fibers. It should be emphasized once again that in all these cases the air box is not connected to a blower with which an air pressure, albeit low, is generated in the air box. Rather, the fact that a pressure gradient arises which is directed from the spinning chamber into the air box and from there into the cooling tube is used for the air supply.
Es können Maßnahmen vorgesehen werden, um die von außen nach innen in das Kühlrohr eingesogenen Luftströmungen zu dirigieren. Dies kann insbesondere durch Leitringe geschehen, die an der Innenwand des Kühlrohres in einer oder mehreren Normalebenen angebracht und im wesentlichen radial nach innen gerichtet sind. Selbstverständlich lassen diese Leitringe im Zentrum des Kühlrohres eine Durchtrittsöffnung für das Chemiefaserbündel frei. Bei der Ausgestaltung nach Anspruch 4 erreicht man neben der zweckmäßigen Umlenkung des Luftstromes auch, daß auf der Unterseite der Leitringe ein Unterdruck entsteht, der zur Vor-Ansaugung der Außenluft führt. Im folgenden wird die Erfindung anhand von Ausführungsbeispielen beschrieben:
Durch die Ausgestaltung nach Anspruch 5 kann man in dem Luftkasten einen definierten Unterdruck erzeugen und dadurch die dem Faden zugeführte Luftmenge steuern. Hierdurch läßt sich die Kühlwirkung dem Bedarf und den technologischen Notwendigkeiten anpassen.Measures can be provided to direct the air currents drawn into the cooling tube from the outside in. This can be done in particular by guide rings which are attached to the inner wall of the cooling tube in one or more normal planes and are directed essentially radially inwards. Of course, these guide rings leave a passage opening for the chemical fiber bundle in the center of the cooling tube. In the embodiment according to claim 4, in addition to the appropriate deflection of the air flow, a vacuum is also created on the underside of the guide rings, which leads to pre-suction of the outside air. The invention is described below using exemplary embodiments:
Due to the configuration according to claim 5, a defined negative pressure can be generated in the air box and thereby the amount of air supplied to the thread can be controlled. As a result, the cooling effect can be adapted to the needs and technological needs.

Allen Ausführungsbeispielen ist gemeinsam, daß die Filamente zunächst im offenen Zustand, d. h. vor dem Fadenführer 7, durch ein Kühlrohr 5 geleitet werden. Das Kühlrohr 5 schließt sich unmittelbar an die Spinndüse 3 an. Das Kühlrohr 5 ist porös. Es hat eine Länge von 0,5 bis 2,0 Metern. An das Austrittsende des Kühlrohres 5 legt sich ein Abschirmblech 6 an. Das Abschirmblech 6 weist eine Durchtrittsöffnung für das Filamentbündel auf, dessen Weite gleich oder kleiner als die lichte Weite des Kühlrohres 5 ist.All of the exemplary embodiments have in common that the filaments are initially in the open state, ie. H. in front of the
In allen Ausführungsbeispielen ist dargestellt, daß die Porosität des Kühlrohres 5 in Fadenlaufrichtung zunimmt. Erfindungsgemäß ist die Porosität im wesentlichen proportional, zumindest aber abhängig von der Fadenlaufgeschwindigkeit. Die Fadenlaufgeschwindigkeit - oder richtiger gesagt: die Laufgeschwindigkeit der Filamente - ist sehr charakteristisch und zeichnet sich dadurch aus, daß sie zunächst verhältnismäßig niedrig ist und sodann sehr stark zunimmt (Diagramm). Die Porosität kann auch dem Temperaturverlauf angepaßt sein, den die Filamente über ihre Länge haben. In beiden geschilderten Fällen nimmt die Porosität in Fadenlaufrichtung zu, d. h. die Luftdurchlässigkeit wird größer.In all exemplary embodiments it is shown that the porosity of the cooling tube 5 increases in the direction of the thread. According to the invention, the porosity is essentially proportional, but at least depends on the thread running speed. The Thread speed - or more correctly: the speed of the filaments - is very characteristic and is characterized by the fact that it is initially relatively low and then increases very much (diagram). The porosity can also be adapted to the temperature profile that the filaments have over their length. In both of the cases described, the porosity increases in the thread running direction, ie the air permeability increases.
Das Ausführungsbeispiel nach Figur 1 weist die Besonderheit auf, daß eine Vielzahl von Schikaneblechen 17 in dem Kühlrohr angeordnet sind. Die Schikanebleche 17 sind ringförmige Bleche. Diese ringförmigen Bleche werden mit ihrem Außenumfang an dem Kühlrohr 5 befestigt und weisen mit ihrer inneren Kante in Fadenlaufrichtung, sind also nach unten geneigt. Diese Schikanebleche 17 leiten die eingesaugten Luftströmungen nach unten, bewirken aber auch, daß unter ihnen ein Unterdruck entsteht, so daß sich hierdurch eine Ansaugwirkung ergibt.The embodiment of Figure 1 has the peculiarity that a plurality of
