Abstract

The invention relates to a parallel spinning process, especially for filaments, e.g. for textile or technical applications, made of polymers such as PET or PA, using a thread intermingling device (8) arranged between two galettes (2, 3) for each individual thread (1). During the spinning start or application process, said galettes are moved in relation to one another so that each individual thread is automatically threaded into its respective intermingling device (8) assigned thereto, and the wrapping angle during the operating mode ranges from at least 85° to a maximum of 200°, preferably from 175° to 185°.

Spinnanlage hierzuSpinning plant for this
Die Erfindung betrifft ein Parallel-Spinnverfahren und damit ausgestattete Spinnanlagen, insbesondere für Filamente, z.B. für textile oder technische Anwendungen, aus Polymeren wie z.B. Polyester oder Polyamid, mit jeweils einer Fadenverwirbelungsvorrichtung zwischen zwei Galetten.The invention relates to a parallel spinning process and spinning plants equipped therewith, in particular for filaments, e.g. for textile or technical applications, made of polymers such as Polyester or polyamide, each with a thread interlacing device between two godets.
Spinnanlagen für konventionelle POY-Spinnprozesse (POY = partially oriented yarn) sind üblicherweise mit zwei separat angetriebenen und drehzahlgeregelten Galetten, über die mehrere Fäden (vier, sechs oder acht je nach Wickler) in einem S-förmigen Fadenlauf geführt werden, zur Regulierung der Fadenspannung zwischen der Fadenölung und der Aufspulung ausgestattet. Bei diesem Fadenlauf werden die frisch ersponnenen Filamentscharen zunächst parallel neben einander zu den entsprechenden Fadenölern geführt, dort jeweils zu einem Faden geschlossen und danach werden die Fäden eng neben einander zusammengefasst über die oben erwähnten Galetten geführt. Anschließend wird die Fadenschar entsprechend der gewünschten Spulenbreite um 90° gedreht wieder aufgefächert dem Wickler zugeführt. Um einen besseren Fadenschluss zu erreichen, werden häufig pneumatisch betriebene Vorrichtungen zum Fadenverwirbeln, sogenannte Tengeldüsen oder Interlacer, eingesetzt. Dies erfolgt vorteilhafterweise zwischen den Galetten: Einerseits kann man immer noch die Fadenspannung regulieren und andererseits ist das Fadeneinlegen durch den engen Fadenstand erleichtert.Spinning systems for conventional POY spinning processes (POY = partially oriented yarn) are usually with two separately driven and speed-controlled godets, over which several threads (four, six or eight depending on the winder) are guided in an S-shaped thread run to regulate the thread tension between the thread oiling and the winding. In this thread run, the freshly spun filament coulters are first guided in parallel next to each other to the corresponding thread oilers, each closed there to form a thread, and then the threads are guided close together over the godets mentioned above. Then the group of threads is fanned out and fed back to the winder according to the desired bobbin width by 90 °. In order to achieve a better thread closure, pneumatically operated devices for thread swirling, so-called tengel nozzles or interlacers, are often used. This is advantageously done between the godets: on the one hand you can still regulate the thread tension and on the other hand the thread insertion is made easier by the narrow thread stand.
Im Gegensatz zu diesem gekreuzten Fadenlauf (die Ausspinnachse ist zur Wicklerachse um 90° gedreht) ist im Parallel-Spinnprozess, wie z.B. nach US 3 902 853, die Anordnung von Interlacern und Handhabung zwischen Galetten bisher nicht gerade einfach, bzw. grundsätzlich noch nicht gelöst. Modernere Parallel-Spinnprozesse sind bisher hauptsächlich als SHSS- (Super-High- Speed-Spinning, Fa. Lurgi Zimmer) oder HOY-Prozesse (HOY = high oriented yarn) konzipiert, bei denen man direkt, d. h. ohne Galetten zur Fadenspannungsregelung, parallel und senkrecht, aus den Spinndüsen auf den Wickler geht Diese kostengünstige und kompakte Bauweise bietet aber nicht nur Vorteile: Neben den prozesstechnischen Nachteilen bezüglich Fadengleichmässigkeit, Spulenaufbau und eingeschränkter Titerpalette ist das Einfädeln und Anlegen zu Beginn des Spinnprozesses in diesen platzsparenden Kurzspinnanlagen aber sehr zeitaufwendig und höchst unkomfortabel.In contrast to this crossed thread path (the spinning axis is rotated by 90 ° to the winder axis), the arrangement of interlacers and handling between godets in the parallel spinning process, for example according to US Pat , Up to now, more modern parallel spinning processes have mainly been designed as SHSS (Super High Speed Spinning, Lurgi Zimmer) or HOY (HOY = high oriented yarn) processes, in which one can directly, ie without godets for thread tension control, parallel and vertical, from the spinnerets to the winder This inexpensive and compact design does not only offer advantages: In addition to the process-related disadvantages with regard to thread uniformity, bobbin build-up and limited titer range, threading and applying at the beginning of the spinning process in these space-saving short spinning systems is very time-consuming and extremely uncomfortable ,
Für POY-Spinnprozesse werden Parallel-Spiπnanlagen bisher üblicherweise mit zwei sehr teueren Langgaletten ausgerüstet wie z. B. nach WO 96/09425, zwischen denen die Tengeldüsen untergebracht sind. Auch hier ist das Einfädeln und Anlegen langwierig und unbequem, außerdem erfordert das Auflegen, schon aus Sicherheitsgründen, einen gewissen Platzbedarf.For POY spinning processes, parallel spinning systems have hitherto usually been equipped with two very expensive long godets, such as. B. according to WO 96/09425, between which the Tengeldüsen are housed. Here, too, threading and putting on is lengthy and uncomfortable, and also laying on requires a certain amount of space, for safety reasons alone.
Ein weiterer POY-Spinnprozess, bei dem für jeden Faden ein kleines Galettenpaar vorgesehen ist, wurde auf der ITMA im Juni 1999 in Paris von Fa. Barmag vorgestellt. In dieser Konfiguration können keine Interlacer zwischen den kleinen Galetten untergebracht werden. Diese Lösung ist zwar wesentlich preisgünstiger als die Langgaletten-Version, aber weil die Funktion der Fadenspannungsregelung bei dem geringen Umschlingungswinkel von unter 90° in dieser Anordnung der kleinen Galetten nicht ausreichend gegeben ist, wurde konsequeπterweise auch auf separate Antriebe und Drehzahlregelungen verzichtet Den geringen Investmentkosten stehen also erhebliche Verfahrensnachteile gegenüber: Ungenügende Umschlingung, keine Drehzahl- bzw. Fadenspannungsregelung, fehlendes Entangling zwischen den Galetten und erheblicher Platzbedarf bei der Maschinenaufstellung für das zeitaufwendige Einfädeln und Auflegen.A further POY spinning process, in which a small pair of godets is provided for each thread, was presented by the Barmag company at the ITMA in Paris in June 1999. In this configuration, interlacers cannot be placed between the small godets. This solution is much cheaper than the long godet version, but because the function of the thread tension control with the low wrap angle of less than 90 ° in this arrangement of the small godets is not sufficiently given, separate drives and speed controls were consequently dispensed with. The low investment costs are incurred So significant process disadvantages compared to: Inadequate wrap, no speed or thread tension control, lack of entangling between the godets and considerable space requirement when setting up the machine for the time-consuming threading and laying on.
So stellt sich für POY-Spinnprozesse in Parallel-Spinnanlagen die Aufgabe eine bedienungsfreundliche und funktionsfähigere Vorrichtung zur Regelung der Fadenspannung und zur Fadenverwirbelung zu finden.For POY spinning processes in parallel spinning systems, the task is to find a user-friendly and more functional device for regulating the thread tension and for swirling the thread.
Erfindungsgemäß wird die Aufgabe durch das Verfahren und die Vorrichtung nach den Patentansprüchen gelöst. In der erfindungsgemäßen Anordnung von Galetten und Interlacern erreicht man bei überraschend bedienungsfreundlicher Handhabung und vollster Erfüllung der gewünschten Funktionen die Lösung der Aufgabe. Mit dem neuen Konzept werden gravierende Prozess- und Handling-Vorteile erreicht, die die höhere Investition über die Betriebszeit schnell amortisieren: Ein sehr großer Umschlingungswinkel von über 180° ist machbar, ebenso die Fadenverwirbelung zwischen den Galetten und der Einsatz drehzahlgeregelter Antriebe zur Steuerung der Fadenspannung. Ferner die selbsttätige Einfädelung in der Tengeldüsen und über die Galetten, die als überraschende Hanhabungslösung durch verkürzte Anlegezeiten die Effektivität der Anlagen verbessert.According to the invention, the object is achieved by the method and the device according to the patent claims. In the arrangement of godets and interlacers according to the invention, the task is solved with surprisingly user-friendly handling and full fulfillment of the desired functions. The new concept achieves serious process and handling advantages that quickly amortize the higher investment over the operating time: a very large wrap angle of over 180 ° is feasible, as is thread swirling between the godets and the use of speed-controlled drives to control the thread tension , Furthermore, the automatic threading in the tenon nozzle and via the godets, which, as a surprising handling solution, improves the effectiveness of the systems through shorter application times.
In der vorgeschlagenen erfindungsgemäßen Anordnung werden pro Faden (1) je zwei Galetten (2; 3) dergestalt eingesetzt, dass im Betriebszustand der Anlage an den Galetten (2; 3) jeweils eine Umschlingung durch den Faden (1) von mindestens 85° bis maximal 200°; vorzugsweise jedoch von 175° bis 185° entsteht. Die Galetten (2) werden hier in der weiteren Beschreibung als „untere" Galetten, die Galetten (3) als „obere" Galetten bezeichnet.In the proposed arrangement according to the invention, two godets (2; 3) are used per thread (1) in such a way that, in the operating state of the system, the thread (1) wraps around the thread (1) from at least 85 ° to a maximum 200 °; but preferably from 175 ° to 185 °. In the further description, the godets (2) are referred to here as “lower” godets, the godets (3) as “upper” godets.
Während der Anlegephase sind dann alle oberen Galetten (3), die auf einer beweglichen Galetteneinheit (4) gemeinsam zusammengefasst sind und auch gemeinsam angetrieben werden, nach unten gefahren, so dass jeder einzelne Faden (1) zunächst vom oberen Fadenführer (5) kommend an der unteren Galette (2) leicht abgeknickend in den zugehörigen Fadenführer des Changierdreiecks (6) einlegt werden kann (vgl. Fig. 1). Nachdem dies für alle Fäden (1) erfolgt ist, wird die Galetteneinheit (4) mit den oberen Galetten (3), um Kollisionen mit den unteren Galetten (2) zu vermeiden, auf einer Kurven- oder vorzugsweise Kreisabschnittsbahn (7), nach oben gefahren und dabei jeder einzelne Faden (1) jeweils in den zugehörigen Interlacer (8) eingefädelt (vgl. Fig. 3).During the feed phase, all of the upper godets (3), which are combined on a movable godet unit (4) and are also driven together, are moved downward, so that each individual thread (1) first arrives from the upper thread guide (5) the lower godet (2) can be inserted with a slight kink in the associated thread guide of the traversing triangle (6) (cf. FIG. 1). After this has been done for all threads (1), the godet unit (4) with the upper godets (3), in order to avoid collisions with the lower godets (2), on a curved or preferably circular section path (7), upwards driven and each individual thread (1) in each case threaded into the associated interlacer (8) (cf. FIG. 3).
In der Endstellung für den Betriebszustand (vgl. Fig. 3) ergibt sich dann für jeden Faden eine S-förmige Fadenführung mit jeweils über 180° Umschlingung der Galetten (2; 3) und mit Anordnung der Interlacer (8) zwischen den Galetten (2; 3), was eine problemlose Regulierung der Fadenspannung ermöglicht. Die unteren (2) und oberen (3) Galetten sind antriebstechnisch jeweils zu einer Gruppe zusammengefasst. Diese gruppen¬ mäßige Konfiguration der Galetten (2; 3) ermöglicht kostengünstige Antriebe über Zahnriemen (9; 12) und Regelmöglichkeiten über elektronische Drehzahlsteuerung. Die Gesamtanordnung ist dabei in einem Gehäuse (10) mit Schiebetür (11) untergebracht, die nur zum Anlegen geöffnet wird, so dass eine einfache Absaugung der überschüssigen Präparation, die während der Tengelung vom Faden (1) abgeblasen wird, ermöglicht ist.In the end position for the operating state (cf. FIG. 3), an S-shaped thread guide then results for each thread, each with a 180 ° loop around the godets (2; 3) and with the interlacers (8) arranged between the godets (2 ; 3), which allows easy adjustment of the thread tension. The lower (2) and upper (3) godets are each grouped together in terms of drive technology. These groups ¬ moderate configuration of the galettes (2, 3) enables cost drives via Toothed belt (9; 12) and control options via electronic speed control. The overall arrangement is housed in a housing (10) with a sliding door (11) that is only opened for application, so that the excess preparation that is blown off the thread (1) during suction can be easily extracted.
In einer weiteren Ausgestaltung der Erfindung ist daran gedacht den Einfädelvorgang noch weiter zu vereinfachen, in dem man die Changierfadenführer (6) -in einer horizontal beweglichen Fadenführereinheit (nicht dargestellt) zusammengefasst- so verfährt, dass jeder einzelne Faden (1) zunächst jeweils gerade senkrecht eingefädelt wird und dann alle Fäden (1) gemeinsam so verzogen werden, so dass der erste Kontakt mit den unteren Galetten (2) für alle Fäden (1) gleichzeitig erfolgt. Der weitere Vorgang ist dann wie schon vorstehend beschrieben: die oberen Galetten (3) werden nach oben geführt und die Einfädelung in die jeweiligen Interlacer (8) erfolgt automatisch. Das geschieht dadurch, dass die oberen einzelnen Galetten (3), die gruppenmäßig in der Galetteneinheit (14) zusammengefasst sind, mittels eines Parallel-Schwenkgetriebes (14), vorzugsweise bestehend aus mindestens zwei Schwenkhebeln (15) und einem pneumatischen Antrieb auf einer Kurvenbahn (7) verschwenkt werden, wobei diese Kurvenbahn (7) vorzugsweise einem Kreisabschnitt entspricht (vgl. Fig. 1 bis 4).In a further embodiment of the invention, it is intended to simplify the threading process even further by moving the traversing thread guides (6) - combined in a horizontally movable thread guide unit (not shown) - in such a way that each individual thread (1) is initially straight is threaded and then all threads (1) are warped together so that the first contact with the lower godets (2) for all threads (1) takes place simultaneously. The further process is then as already described above: the upper godets (3) are guided upwards and the threading into the respective interlacer (8) takes place automatically. This happens because the upper individual godets (3), which are grouped together in the godet unit (14), by means of a parallel swivel gear (14), preferably consisting of at least two swivel levers (15) and a pneumatic drive on a cam track ( 7) can be pivoted, this curved path (7) preferably corresponding to a segment of a circle (cf. FIGS. 1 to 4).
