Abstract
Description
Die Erfindung liegt auf dem Gebiet der Offenend-Spinnmaschinen (nachfolgend als OE-Spinnmaschinen
bezeichnet). Diese weisen eine Vielzahl von Arbeitsstellen auf, welche im unteren
Geschwindigkeitsbereich Fadengeschwindigkeiten bis rund 250 m/min (OE-Rotorspinnmaschinen)
und im oberen Geschwindigkeitsbereich Fadengeschwindigkeiten bis rund 500 m/min (OE-Luftspinn-
und OE-Friktionsspinnmaschinen) aufweisen. Die OE-Spinnmaschinen sind als sogenannte
Längsteilmaschinen mit einem zentralen Antrieb und Antriebsstangen für die Arbeitsstellen
ausgebildet. Jede Arbeitsstelle ist jeweils mit einer Spinneinheit und einer Spuleinrichtung
ausgerüstet. In den Spinneinheiten wird das in Spinnkannen vorgelegte Faserband zu Garn gesponnen,
welches auf den Spuleinrichtungen zu Kreuzspulen aufgewickelt wird.
Im Verlauf der Herstellung der Kreuzspulen muss zweimal, vor und nach dem Wickeln, an einer
definierten Stelle relativ zur Spulenachse eine Anzahl von Fadenwicklungen erstellt werden.
Diese Fadenwicklungen werden als Fadenreserve und als Endwicklung bezeichnet, wobei für
die Endwicklung auch die Bezeichnung Endwulst gebräuchlich ist. Sowohl die Fadenreserve als
auch die Endwicklung dienen dazu, auf Gattern oder ähnlichen Aufsteckeinrichtungen hintereinander
liegende Spulen miteinander zu verbinden, so dass die Spulen kontinuierlich hintereinander
ablaufen können.
Die Fadenreserve, die dazu dient, auf einer vollen Spule den Fadenanfang sicher zu finden,
wird vor dem Wickeln des Wickelkörpers auf der Hülse der Spule durch Wickeln einer geringen
Anzahl von Garnwindungen an einem Hülsenende hergestellt, wobei das zuerst auf die Hülse
aufgebrachte Fadenstück durch Windungen der Fadenreserve überdeckt und fixiert wird. Die
Endwicklung, die dazu dient, auf einer vollen Spule das Fadenende sicher zu finden, wird einige
Windungen vor Erreichen der vorgesehenen Spulenlänge beispielsweise auf der Spulenhülse
platziert.
Da die OE-Spinnmaschinen nach dem Stand der Technik als Längsteilmaschinen ausgeführt
sind, bei denen alle Verlegeeinrichtungen die gleiche Hubbewegung ausführen und nicht individuell
steuerbar sind, sind für die Herstellung der Fadenreserve und der Endwicklung zusätzliche
mechanische Mittel erforderlich, welche die betreffende Maschine verteuern. Für die Erstellung
der Endwicklung sind Mittel bekannt, welche die Endwicklung auf der Spulenhülse platzieren,
was in einem separaten Arbeitsgang und an einem speziellen Arbeitsort erfolgt, so dass die
betreffende Spule nicht an ihrer Arbeitsposition fertiggestellt werden kann. The invention is in the field of open-end spinning machines (hereinafter referred to as OE spinning machines). These have a large number of workstations, which have thread speeds of up to around 250 m / min (OE rotor spinning machines) in the lower speed range and thread speeds of up to around 500 m / min (OE air spinning and OE friction spinning machines) in the upper speed range. The OE spinning machines are designed as so-called slitting machines with a central drive and drive rods for the work stations. Each work station is equipped with a spinning unit and a winding device. In the spinning units, the sliver placed in spinning cans is spun into yarn, which is wound up into cross-wound bobbins on the winding devices.
In the course of the production of the packages, a number of thread windings must be created twice, before and after winding, at a defined location relative to the bobbin axis. These thread windings are referred to as the thread reserve and as the end winding, the term end bead also being used for the end winding. Both the thread reserve and the end winding serve to connect coils lying one behind the other on gates or similar plug-on devices, so that the coils can run continuously one behind the other.
The thread reserve, which is used to reliably find the beginning of the thread on a full bobbin, is produced before the winding body is wound on the bobbin tube by winding a small number of thread turns at one end of the tube, with the thread piece first applied to the tube by turns the thread reserve is covered and fixed. The end winding, which is used to reliably find the end of the thread on a full bobbin, is placed a few turns on the bobbin tube, for example, before the intended bobbin length is reached.
Since the OE spinning machines according to the prior art are designed as slitting machines, in which all laying devices carry out the same lifting movement and cannot be controlled individually, additional mechanical means are required for the production of the thread reserve and the end winding, which make the machine in question more expensive. Means are known for the creation of the end winding, which place the end winding on the spool sleeve, which takes place in a separate operation and at a special work location, so that the spool in question cannot be finished at its working position.
Bei einer in der DE-A-42 11 749 beschriebenen Vorrichtung zur Erstellung einer Fadenreserve
wird der Faden zunächst durch eine in den Hülsenteller integrierte Fangnase mitgenommen und
auf die Hülse aufgewickelt, wobei der Faden im Moment des Ergreifens durch die Fangnase
von einer Klemmschere freigegeben wird. Der Faden wird durch die Fangnase mitgenommen,
gerät in einen Fangschlitz und wird zwischen der Stirnseite der Hülse und dem Hülsenteller eingeklemmt.
Dann wird der Faden an einen speziellen Fadenheber übergeben, welcher die Fadenreserve
herstellt. Dabei findet eine Bewegung statt, welche verhindert, dass sich die Fadenreserve
an der fertigen Spule ohne Eingriff von aussen lösen kann. Das Garnstück zwischen
Hülsenteller und der ersten Windung der Fadenreserve wird durch ein scherenartiges Werkzeug
abgeschnitten. Mit dieser Vorrichtung kann zwar eine Fadenreserve einer definierten Länge
und mit sicherer Fixierung auf dem Hülsenende gebildet werden, es wird aber ein separater
Fadenführer für die Bildung der Fadenreserve benötigt.
Durch die Erfindung soll nun eine Vorrichtung zur Erstellung einer Fadenreserve und/oder einer
Endwicklung auf einer eine Fadenverlegung aufweisenden Aufwickelvorrichtung einer OE-Spinnmaschine
angegeben werden, welche zur Erstellung der Fadenreserve beziehungsweise
der Endwicklung keine zusätzlichen mechanischen Mittel erfordert.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass an der Spinnstelle ein frei positionierbarer
und unabhängig von anderen Arbeitspositionen bewegbarer Fadenführer vorgesehen
ist, welcher Teil der Fadenverlegung bildet und für die Erstellung einer Fadenreserve und/oder
einer Endwicklung für eine einstellbare Zeit an der dafür vorgesehenen Stelle positionierbar ist.
Die erfindungsgemässe Lösung hat den Vorteil, dass zur Erstellung der Fadenreserve und/
oder der Endwicklung der ohnehin vorhandene Fadenführer der Fadenverlegung verwendet
wird und somit keinerlei Zusatzaufwand erforderlich ist.
Eine erste bevorzugte Ausführungsform der erfindungsgemässen Vorrichtung ist dadurch gekennzeichnet,
dass der Fadenführer für die Erstellung einer Fadenreserve so positioniert wird,
dass der Faden ausserhalb des normalen Wickelbereichs aufgewickelt wird.
Eine zweite bevorzugte Ausführungsform der erfindungsgemässen Vorrichtung ist dadurch gekennzeichnet,
dass die Anzahl der Windungen der Fadenreserve einstellbar ist.
Eine dritte bevorzugte Ausführungsform der erfindungsgemässen Vorrichtung ist dadurch gekennzeichnet,
dass der Fadenführer für die Erstellung der Endwicklung so positioniert wird,
dass der Faden innerhalb des normalen Wickelbereichs aufgewickelt wird.
Eine vierte bevorzugte Ausführungsform der erfindungsgemässen Vorrichtung ist dadurch gekennzeichnet,
dass der Fadenführer für die Erstellung der Endwicklung so positioniert wird,
dass der Faden ausserhalb des normalen Wickelbereichs aufgewickelt wird. In a device for creating a thread reserve described in DE-A-42 11 749, the thread is first taken along by a catch nose integrated in the sleeve plate and wound onto the sleeve, the thread being released by a pair of scissors at the moment of being caught by the catch nose . The thread is carried by the catch nose, gets into a catch slot and is clamped between the face of the sleeve and the sleeve plate. Then the thread is transferred to a special thread lifter, which creates the thread reserve. There is a movement that prevents the thread reserve on the finished bobbin from being released without outside intervention. The piece of yarn between the core plate and the first turn of the thread reserve is cut off by a scissor-like tool. With this device, a thread reserve of a defined length and with secure fixation on the sleeve end can be formed, but a separate thread guide is required for the formation of the thread reserve.
The invention is now intended to provide a device for creating a thread reserve and / or an end winding on a winding device of an OE spinning machine which has thread laying and which does not require any additional mechanical means for creating the thread reserve or the end winding.
This object is achieved according to the invention in that a freely positionable thread guide which can be moved independently of other working positions is provided at the spinning station, which forms part of the thread laying and can be positioned for an adjustable time at the location provided for the creation of a thread reserve and / or an end winding is.
The solution according to the invention has the advantage that the thread guide of the thread laying, which is present anyway, is used to create the thread reserve and / or the end winding and therefore no additional effort is required.
A first preferred embodiment of the device according to the invention is characterized in that the thread guide for the creation of a thread reserve is positioned such that the thread is wound outside the normal winding area.
A second preferred embodiment of the device according to the invention is characterized in that the number of turns of the thread reserve is adjustable.
A third preferred embodiment of the device according to the invention is characterized in that the thread guide for the creation of the end winding is positioned such that the thread is wound within the normal winding range.
A fourth preferred embodiment of the device according to the invention is characterized in that the thread guide for the creation of the end winding is positioned in such a way that the thread is wound outside the normal winding area.
Wenn der Fadenführer für die Erstellung der Endwicklung so positioniert wird, dass sich der Faden
innerhalb des normalen Wickelbereichs befindet, wird die Endwicklung auf dem Spulenkörper
erstellt. In diesem Fall ist zu beachten, dass die Erstellung der Endwicklung bei verminderter
Aufwickelspannung erfolgt, damit in der Spule keine Einschnürungen entstehen. Vorzugsweise
weist die Endwicklung einen von der Normalwicklung abweichenden, kleineren Kreuzungswinkel
auf.
Wenn der Fadenführer für die Erstellung der Endwicklung so positioniert wird, dass sich der Faden
ausserhalb des normalen Wickelbereichs befindet, wird die Endwicklung auf der Spulenhülse
erstellt. Da dann die Aufwickelgeschwindigkeit nicht mehr der Oberflächengeschwindigkeit
der Spule entspricht, wird die Drehzahl der Spule entsprechend dem jeweiligen Leerhülsendurchmesser
erhöht. In diesem Fall ist es vorteilhaft, die Endwicklung am gleichen Ende der
Spulenhülse zu platzieren wie die Fadenreserve, damit bei der Weiterverarbeitung in einem
Spulengatter der Zugriff zu Endwicklung und Fadenreserve von einer Seite der Spule möglich
ist.
Im folgenden wird die Erfindung anhand von Ausführungsbeispielen und der Zeichnungen näher
erläutert; es zeigt:

Mit ein Grund für die Möglichkeit, das System im Open-Loop-Modus betreiben zu können, ist die beschriebene Reduktion des auf die Motorwelle wirkenden Trägheitsmoments. Denn diese Reduktion hat zur Folge, dass die Fadenverlegung rein mechanisch sehr robust ist, so dass in der Regel die programmierten Hublängen auch eingehalten werden und keine Abweichungen auftreten. Erst bei Aggregaten für höhere und höchste Geschwindigkeiten empfiehlt es sich, das System als rückgekoppeltes Regelsystem auszuführen. In diesem Fall ist es vorteilhaft, auf der Motorwelle des Motors des Verlegeantriebs 4 einen Winkelsensor vorzusehen, um anhand der Winkelposition der Motorwelle die Hubposition des Fadenverlegehebels 5 zu bestimmen und bei Abweichungen zwischen Ist- und Sollwert den Motor entsprechend nachzuregeln. Für noch höhere Geschwindigkeiten können Energiespeicher zur Beeinflussung der Verzögerung und Beschleu-nigung des Fadenverlegehebels 5 bei seiner Bewegungsumkehr vorgesehen sein. Bezüglich derartiger Energiespeicher wird auf die EP-A-0 838 422 verwiesen.

Der Verlegeantrieb 4 kann auch ausserhalb des staubdichten Gehäuses angeordnet sein. Zu diesem Zweck würde die Welle des
If the thread guide for creating the end winding is positioned so that the thread is outside the normal winding area, the end winding is created on the bobbin tube. Since the winding speed then no longer corresponds to the surface speed of the coil, the speed of the coil is increased in accordance with the respective empty tube diameter. In this case, it is advantageous to place the end winding at the same end of the bobbin tube as the thread reserve so that the end winding and thread reserve can be accessed from one side of the bobbin during further processing in a creel.
The invention is explained in more detail below with the aid of exemplary embodiments and the drawings; it shows:

One of the reasons for the possibility of being able to operate the system in open loop mode is the described reduction in the moment of inertia acting on the motor shaft. Because this reduction means that the thread laying is mechanically very robust, so that the programmed stroke lengths are generally adhered to and no deviations occur. Only for units for higher and highest speeds is it advisable to design the system as a feedback control system. In this case, it is advantageous to provide an angle sensor on the motor shaft of the motor of the laying drive 4 in order to determine the stroke position of the

Der Einsatz des beschriebenen Spulkopfmoduls mit der elektronisch gesteuerten Fadenverlegung und einer Reibwalze, wobei Fadenverlegung und Reibwalze individuell angetrieben sind, ermöglicht unter anderem:
- Alle bekannten Wickelgesetze, wie wilde Wicklung mit Bildverhütung, Präzisionswicklung und Stufenpräzisionswicklung.
- Eine höhere Spulendichte infolge von Präzisionswicklung (geschlossenes Windungsverhältnis) oder Stufenpräzisionswicklung (geschlossenes Windungsverhältnis).
- Eine konstantere Spulendichte für Färbespulen durch Präzisionswicklung (offenes Windungsverhältnis) oder Stufenpräzisionswicklung (offenes Windungsverhältnis).
- Einen in Grenzen frei wählbaren Spulenhub, insbesondere frei wählbare Spulenhöhe, Hubvariation (Reduzierung der Spulenkantenhärte), Hubverkürzung (Reduzierung von Fallfäden), Hubverlegung (Reduzierung der Spulenkantenhärte).
- Eine frei wählbare Spulengeometrie (zylindrische, konische, bikonische Spulen).
- Bildung einer Fadenreservewicklung.
- Freie Positionierung einer Endwulstwicklung am Aussendurchmesser der Spule.
- Exakte Fadenlängenmessung.
- Kompensation der Schlepplänge.
Bei der Herstellung von Spulen muss zweimal, vor und nach dem Wickeln der eigentlichen Spule, an einer definierten Stelle relativ zur Achse der Spule 7 oder der Spulenhülse 19 eine Anzahl von Fadenwicklungen erstellt werden. Die vor dem
Die Fadenreserve wird vor dem Wickeln des Wickelkörpers auf der Hülse der Spule durch Wikkeln einer geringen Anzahl von Garnwindungen an einem Hülsenende hergestellt, wobei das zuerst auf die Hülse aufgebrachte Fadenstück durch Windungen der Fadenreserve überdeckt und fixiert wird. Die Endwicklung wird einige Windungen vor Erreichen der vorgesehenen Spulenlänge beispielsweise auf der Spulenhülse platziert.
Fig. 2 zeigt eine leere Spulenhülse 19 mit einer ausserhalb des normalen Wickelbereichs erstellten Fadenreserve F. Der normale Wickelbereich ist durch eine strichpunktierte Spule 7 angedeutet. Für die Erstellung der Fadenreserve wird der Fadenverlegehebel 5 so positioniert, dass der Faden ausserhalb des normalen Wickelbereichs (aber selbstverständlich im Bereich der Spulenhülse 19) aufgewickelt wird. An dieser Position wird er für die gewählte Windungszahl der Fadenreserve belassen und beginnt anschliessend mit der normalen Verlegebewegung zur Herstellung des Spulenkörpers. Während der Erstellung der Fadenreserve führt der Fadenverlegehebel 5 eine leichte Changierbewegung aus, damit die einzelnen Fadenlagen nicht offen auf der Spulenhülse 19 liegen.
Gemäss Fig. 4 wird die Endwicklung E auf der Spulenhülse 19 platziert, wobei zwischen der Endwicklung E und dem Spulenkörper ein Verbindungsfaden V gebildet ist. Die Endwicklung E kann vorzugsweise auf das gleiche Ende der
