Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Zwirns in einem integrierten Spinn-Zwirnprozeß nach dem Doppeldrahtprinzip mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens mit den Merkmalen gemäß dem Oberbegriff des Patentanspruchs 5.The invention relates to a method for producing a Thread in an integrated spin-twist process after Double-wire principle with the features from the generic term of claim 1 and a device for performing of the method with the features according to the preamble of claim 5.
Ein derartiges Verfahren und die entsprechende Vorrichtung sind in DE 44 27 875 C1 beschrieben. Such a method and the corresponding device are described in DE 44 27 875 C1.
Bei dem aus der oben genannten Druckschrift bekannten Verfahren und der bekannten Vorrichtung wird das aufgelöste Fasermaterial zunächst über einen Faserkanal einem Ringraum zugeführt, der koaxial zur Spindelachse angeordnet ist. Durch diesen Ringraum wird der den Fadenballon bildende Faden geführt und zwar derart, daß er den Ringraum in einer Art Säule oder Speiche durchquert, die Teil eines rotieren den Bauteiles ist, so daß der den Fadenballon bildende Faden nicht in direkten Kontakt mit dem zugeführten Fasermaterial kommt. Bei dieser Konstruktion ging man von dem Grundgedanken aus, daß Faserstrom und durchlaufender Faden sich möglichst wenig gegenseitig stören sollen. Die Speiche oder Säule, durch welche der Faden geführt ist, konnte dabei so ausgestaltet sein, daß sich daran keine Fasern anlegen können. Bei einer Vorrichtung zur Durchführung dieses bekannten Verfahrens ist das rotierende Bauteil, welches das Fadenleitelement enthält, mittels dessen der Faden im Fadenballon geführt ist, als mit dem Spindelrotor fest verbundener Topf ausgebildet, an dessen oberem Ende zwei in axialer Richtung einander gegenüberliegende ringförmige Bauteile angeordnet sind, die zwischen sich den Ringraum begrenzen. Die beiden ringförmigen Teile sind durch speichenartige Verbindungselemente, die den Ringraum durchsetzen, miteinander verbunden, wobei das Fadenleitelement in einem der Verbindungselemente angeordnet ist.In the method known from the above-mentioned document and the known device is the resolved Fiber material first through a fiber channel to an annulus supplied, which is arranged coaxially to the spindle axis. By the thread forming the thread balloon is guided in this annular space in such a way that the ring space is in a kind of column or spoke crosses that part of a rotating component is so that the thread forming the thread balloon is not comes into direct contact with the supplied fiber material. With this construction, the basic idea was assumed that fiber flow and thread running through as little as possible should interfere with each other. The spoke or column, through which the thread is guided could be designed in this way be that no fibers can attach to it. At a Device for performing this known method is the rotating component, which contains the thread guide element, by means of which the thread is guided in the thread balloon, as pot firmly connected to the spindle rotor, at the top two in the axial direction to each other opposed annular components are arranged, that limit the annulus between them. The two ring-shaped Parts are through spoke-like connecting elements, that penetrate the annulus, connected to each other, the thread guide element in one of the connecting elements is arranged.
An sich würde ein das Fadenleitelement enthaltende Verbindungselement auf dem Umfang des Topfes zur Führung des Fadens durch den Ringraum ausreichen. Dies ist aber maschinenbautechnisch wegen der auftretenden Unwucht ungünstig. Besser ist es, wenn mindestens zwei, vorzugsweise drei derartige speichenartige Verbindungselemente auf dem Umfang vorhanden sind. Dies hat aber zur Folge, daß der Faserstrom pro Spindelumlauf eine dreifache Störung erleidet. Da die Verbindungselemente aus konstruktiven Gründen eine bestimmte Mindestbreite in Umfangsrichtung besitzen müssen, kommt es auch bei einem strömungstechnisch guten Profil der Verbindungselemente zum Herausschleudern von Einzelfasern aus dem Faserstrom und damit zu einer Faserdesorientierung.As such, a connecting element containing the thread guide element would on the circumference of the pot to guide the Sufficient thread through the annulus. But this is mechanical engineering unfavorable because of the imbalance that occurs. It is better if at least two, preferably three such spoke-like connecting elements on the circumference available. However, this has the consequence that the fiber stream triple malfunction per spindle revolution. Since the Fasteners a certain for design reasons It must have a minimum width in the circumferential direction even with a good fluidic profile of the connecting elements for ejecting single fibers from the Fiber flow and thus to fiber disorientation.
Weiterhin hat sich gezeigt, daß die zwischen den ringförmigen Teilen des Topfes angeordneten Verbindungselemente eine Quelle hoher Geräuschemission sind. Sie wirken trotz günstigem Strömungsprofil wie eine Sirene, deren Ton trotz einer gekapselten Ausführung in unannehmbarer Stärke nach außen hervortritt.It has also been shown that the between the annular Parts of the pot arranged fasteners Source of high noise emissions. They work despite the cheap Flow profile like a siren, whose sound despite one encapsulated version in unacceptable strength to the outside emerges.
Der Erfindung Liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 bzw. 5 so auszugestalten, daß bei der Zuführung des Fasermaterials eine minimale Faserdesorientierung auftritt und die Geräuschbildung erheblich herabgesetzt wird.The invention has for its object a method and a device with the features from the preamble of Claim 1 or 5 so that the feed minimal fiber disorientation of the fiber material occurs and the noise is significantly reduced.
Die Lösung dieser Aufgabe erfolgt verfahrensmäßig mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1 und bezüglich der Vorrichtung mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 5.This task is solved procedurally with the Features from the characterizing part of the claim 1 and with respect to the device with the features from characterizing part of claim 5.
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.Advantageous developments of the invention are in the dependent Described claims.
Der Grundgedanke der Erfindung besteht darin, den den Fadenballon bildenden Faden frei, also ohne Führung durch ein geschlossenes Fadenleitelement durch den Ringraum zu führen. Quer zum Ringraum wird nach wie vor der aufgelöste Faserstrom zugeführt. Im Gegensatz zu dem bekannten Verfahren quert der Fadenballon bzw. der den Fadenballon bildende Faden den Faserstrom völlig ungeschützt. The basic idea of the invention is the thread balloon free thread, that is, without guidance through a closed Guide the thread guide through the annulus. The dissolved fiber flow is still transverse to the annulus fed. In contrast to the known method, the Thread balloon or the thread forming the thread balloon the fiber stream completely unprotected.
Es hat sich überraschenderweise gezeigt, daß diese ungeschützte Führung des Fadens durch den Ringraum nicht nur möglich ist, sondern sogar zu einer wesentlich geringeren Störung des Faserstroms führt. Es ergibt sich ein wesentlich besseres textiltechnologisches Ergebnis im Endprodukt Zwirn, und die Fasersubstanzausnutzung ist erheblich höher. Weiterhin ist die Geräuschbildung ebenfalls erheblich herabgesetzt. Als zusätzlicher Vorteil hat sich herausgestellt, daß eine nach dem erfindungsgemäßen Verfahren arbeitende Vorrichtung mit einer gegenüber der bekannten Vorrichtung geringeren Bauhöhe auskommt. Dies ist darauf zurückzuführen, daß die sich in axialer Richtung erstreckenden, den Ringraum begrenzenden, ringförmigen Teile nicht vorhanden sind. Der Faden kann direkt durch einen den Ringraum an der Fadenabführungsseite begrenzenden Ringspalt mit einer Breite von ca. 4 mm aus dem Ringraum herausgeführt und zum Zentrierpunkt geführt werden.It has surprisingly been found that this is unprotected Not only guiding the thread through the annulus is possible, but even to a much lower one Disruption of the fiber flow leads. There is an essential better textile technology result in the end product Thread, and the fiber utilization is significantly higher. Furthermore, the noise level is also significantly reduced. It turned out to be an additional advantage that a working according to the inventive method Device with a compared to the known device needs less height. This is due to, that the axially extending, the annulus limiting annular parts are not present. The Thread can go directly through the ring space on the thread removal side limiting annular gap with a width of approx. 4 mm out of the annulus and to the centering point be performed.
Die Erfindung eröffnet noch eine weitere Möglichkeit, die
Faserdesorientierung bei der Zuführung des Fasermaterials
herabzusetzen. Zur Zuführung des Fasermaterials wird der
Ringraum mit Unterdruck beaufschlagt. Der Unterdruckfluß
kann nun vom Ringraum aus einerseits in die Fasermaterialzuführungskanäle
eingeführt werden und andererseits durch
den an der Fadenaustrittsseite des Ringraums liegenden
Ringspalt in einen abgeschlossenen Raum zwischen der Oberseite
des Innengehäuses und dem die Zentrieröffnung aufweisenden
Deckel des Außengehäuses. Hierdurch entsteht ein Luftstrom
aus diesem Raum durch den Ringspalt in den Ringraum
hinein, der die Tendenz hat, desorientierte Fasern, die in
diesen Raum oder in den Ringspalt eingedrungen sind, in den
Ringraum zurückzufördern, so daß eine hohe Wahrscheinlichkeit
einer Neuorientierung dieser desorientierten Fasern auftritt.
Um eine bessere Kontrollmöglichkeit dieses Luftstroms zu erhalten,
ist es zweckmäßig, wenn der Unterdruckfluß von der
an die Spindelhohlachse angeschlossenen Unterdruckquelle aus
ohne einen in den Außenraum geführten Bypass zum Ringraum
geführt ist (vergleiche Ansprüche 4, 7, 8 und 10). Eine Abdichtung
des Ringraumes im Hinblick auf den Unterdruck braucht
nur noch zur Fadenzuführungsseite, also nach unten aufrecht
erhalten zu werden.The invention opens up yet another possibility that
Fiber disorientation when feeding the fiber material
belittling. To feed the fiber material, the
Pressurized annulus. The vacuum flow
can now on the one hand into the fiber material feed channels from the annular space
be introduced and on the other hand by
the one on the thread exit side of the annular space
Annular gap in a closed space between the top
of the inner housing and the one with the centering opening
Cover of the outer housing. This creates an air flow
from this room through the annular gap into the annular space
that tends to disorient fibers that are in
have penetrated this space or into the annular gap into the
Promote annulus back, making it highly likely
a reorientation of these disoriented fibers occurs.
To get a better control over this airflow,
it is useful if the vacuum flow from the
vacuum source connected to the spindle hollow axis
without a bypass leading to the annulus
is performed (see
Es wird damit insgesamt eine bessere Aufteilung der unter Unterdruck stehenden gegenüber den unter höherem Druck stehenden Innenräumen der Zwirnspindel erreicht, was zur Folge hat, daß der für den Fasertransport wichtige negative Druckgradient besser dosierbar ist. Der Unterdruckfluß ist im Gegensatz zum bekannten Verfahren aus dem Ringraum nicht nur durch den Faserzustromkanal geführt, sondern durch den Ringspalt und auch durch die öffnung am Zentrierpunkt des Fadenballons. Eine gewünschte Dosierung des Unterdruckstromes kann dann von dieser Stelle aus einfach, z.B. durch Drosselwirkung vorgenommen werden.It will make a better overall breakdown of the Negative pressure compared to those under higher pressure standing interiors of the twisting spindle, which leads to The consequence is that the negative for fiber transport important Pressure gradient can be metered better. The vacuum flow is in contrast to the known method from the annulus only through the fiber inflow channel, but through the Annular gap and also through the opening at the centering point of the Thread balloons. A desired dosage of the vacuum flow can then be done easily from this point, e.g. by throttling be made.
