Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Arbeitsstelle einer Spinn- und/oder Spulmaschine, die über eine Spinnvorrichtung zur Produktion eines Fadens oder einen Kops zur Zulieferung eines Fadens sowie über eine Spulvorrichtung zur Herstellung einer Kreuzspule auf einer Hülse verfügt, wobei die Spulvorrichtung einen schwenkbar gelagerten Spulenhalter mit Spulenteller zur Aufnahme der Hülse und zum Fangen des Fadens, eine angetriebene Spulwalze zum Drehen der Hülse bzw. der Spule sowie eine Fadenchangiereinrichtung aufweist und die Arbeitsstelle mit einer ersten, auf den Spulenumfang gerichteten Saugdüse und weiterhin mit einer zweiten, auf der von der Kreuzspule abgewandten Seite des Spulentellers angeordneten und im Wesentlichen entgegen der ersten Saugdüse gerichteten und von dieser beabstandeten Saugdüse ausgestattet ist und eine entsprechende Arbeitsstelle einer Spinn- und/oder Spulmaschine.The invention relates to a method for operating a workstation of a spinning and / or winding machine, which has a spinning device for producing a thread or a cop for supplying a thread and a winding device for producing a cross-wound bobbin on a sleeve, wherein the winding device a pivotable Having mounted coil holder with reel plate for receiving the sleeve and for catching the thread, a driven winding roller for rotating the sleeve or the spool and a Fadenchangiereinrichtung and the job with a first, directed towards the circumference of the suction nozzle and further with a second on the of arranged opposite the cross-coil side of the reel disc and substantially directed against the first suction nozzle and spaced therefrom suction nozzle is equipped and a corresponding job of a spinning and / or winding machine.

Aus der DE 10 2012 008 691 A1 ist ein Verfahren zum Betreiben von Arbeitsstellen einer Offenend-Rotorspinnmaschine und eine entsprechende Arbeitsstelle zur Durchführung des Verfahrens bekannt, bei welchen eine erste, schwenkbar gelagerte Saugdüse und eine zweite, beweglich gelagerte Saugdüse vorhanden sind. Die erste, schwenkbar gelagerte Saugdüse nimmt einen Faden von einer Kreuzspule auf und übergibt den Faden im Bereich der Spinnvorrichtung an die Arbeitsstelle. Beim Erreichen eines vorgebbaren Durchmessers der Kreuzspule wird der Wickelprozess unterbrochenen und ein Kreuzspulen-/Hülsenwechsel eingeleitet. Dabei wird der produzierte Faden durch die bedarfsgerecht positionierbare zweite Saugdüse entsorgt. Die beweglich gelagerte zweite Saugdüse wird bei der Übergabe des einlaufenden Fadens an eine leere Hülse so positioniert, dass der Faden in der geeigneten Position gehalten werden kann. Nachteilig hierbei ist es, dass zwei beweglich gelagerte Saugdüsen benötigt werden. Der dafür erforderliche konstruktive Aufwand der Lagerung der Saugdüsen ist dabei aufwändig und erfordert einen hohen Steuerungsaufwand. Darüber hinaus ist die Bewegung der Saugdüsen zeitintensiv und geht zu Lasten der Produktivität der Arbeitsstelle.From the DE 10 2012 008 691 A1 a method for operating jobs of an open-end rotor spinning machine and a corresponding job for performing the method is known in which a first, pivotally mounted suction nozzle and a second, movably mounted suction nozzle are present. The first, pivotally mounted suction nozzle picks up a thread from a cross-wound bobbin and transfers the thread in the area of the spinning device to the workstation. Upon reaching a predetermined diameter of the cheese, the winding process is interrupted and initiated a cheese / sleeve change. The produced thread is disposed of by the second suction nozzle which can be positioned as required. The movably mounted second suction nozzle is positioned at the transfer of the incoming thread to an empty sleeve so that the thread can be held in the appropriate position. The disadvantage here is that two movably mounted suction nozzles are needed. The required design effort for the storage of the suction nozzles is complex and requires a lot of control. In addition, the movement of the suction nozzles is time-consuming and at the expense of the productivity of the job.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Vorrichtung zu schaffen, mit welchen ein Faden auf eine leere Hülse einer Spinn-und/oder Spulmaschine schnell und konstruktiv einfach angelegt werden kann.Object of the present invention is to provide a method and an apparatus with which a thread can be applied to an empty shell of a spinning and / or winding machine quickly and structurally simple.

Die Aufgabe wird gelöst mit einem Verfahren und einer Arbeitsstelle gemäß den Merkmalen der unabhängigen Patentansprüche.The object is achieved with a method and a workstation according to the features of the independent claims.

Das erfindungsgemäße Verfahren zum Betreiben einer Arbeitsstelle einer Spinn- und/oder Spulmaschine, dient zum Anlegen eines Fadens an eine leere Hülse. Eine geeignete Spinnmaschine kann eine Offenend-Rotorspinnmaschine oder eine Luftspinnmaschine sein. Auch eine Spulmaschine, welche anstelle einer Spinnvorrichtung zur Produktion eines Fadens einen Kops aufweist, von welchem Faden geliefert wird und auf eine Kreuzspule aufgespult wird, ist zur Anwendung des erfindungsgemäßen Verfahrens geeignet. Die Arbeitsstelle verfügt über eine Spinnvorrichtung zur Produktion eines Fadens oder einen Kops zur Zulieferung eines Fadens sowie über eine Spulvorrichtung zur Herstellung einer Kreuzspule auf einer Hülse. Die Spulvorrichtung weist einen schwenkbar gelagerten Spulenhalter mit Spulenteller zur Aufnahme der Hülse und zum Fangen des Fadens, eine angetriebene Spulwalze zum Drehen der Hülse bzw. der Spule sowie eine Fadenchangiereinrichtung auf. Die Arbeitsstelle ist mit einer ersten, auf den Spulenumfang gerichteten Saugdüse und weiterhin mit einer zweiten, auf der von der Kreuzspule abgewandten Seite des Spulentellers angeordneten und im Wesentlichen entgegen der ersten Saugdüse gerichteten und von dieser beabstandeten Saugdüse ausgestattet.The inventive method for operating a job of a spinning and / or winding machine, is used for applying a thread to an empty sleeve. A suitable spinning machine may be an open-end rotor spinning machine or an air-spinning machine. Also, a winding machine, which instead of a spinning device for producing a thread has a cop from which yarn is supplied and is wound on a cross-wound bobbin, is suitable for the application of the method according to the invention. The work station has a spinning device for producing a thread or a cop for supplying a thread and a winding device for producing a cross-wound bobbin on a sleeve. The winding device has a pivotally mounted reel holder with reel disc for receiving the sleeve and for catching the thread, a driven winding roller for rotating the sleeve or the reel, and a thread-changing device. The workstation is arranged with a first, directed onto the coil circumference suction nozzle and further with a second, arranged on the side facing away from the cross-wound side of the reel disc and substantially directed against the first suction nozzle and spaced therefrom suction nozzle.

Erfindungsgemäß wird der Faden zum Anlegen an eine leere Hülse in den beiden Saugdüsen angeordnet und dazwischen insbesondere mittels Unterdruck in zumindest der zweiten Saugdüse aufgespannt. Das andere Ende des Fadens kann durch die erste Saugdüse verlaufen und ebenfalls mittels Unterdruck oder mittels einer Klemmeinrichtung, beispielsweise zwischen Klemmwalzen, gehalten werden. Anstelle des Unterdrucks kann die Aufspannung des Fadens auch beidseitig mittels einer Klemmeinrichtung erfolgen, die beispielsweise in den oder im Bereich der Saugdüsen angeordnet ist. Außerdem ist es möglich, dass der Faden durch die beiden Saugdüsen hindurch in Bewegung ist, insbesondere wenn die Spinnvorrichtung während der Anwendung des Verfahrens weiter produziert und der Faden durch die zweite Saugdüse abgesaugt wird.According to the invention, the thread is arranged for application to an empty sleeve in the two suction nozzles and clamped therebetween in particular by means of negative pressure in at least the second suction nozzle. The other end of the thread can pass through the first suction nozzle and also be held by means of vacuum or by means of a clamping device, for example between pinch rollers. Instead of the negative pressure, the clamping of the thread can also be done on both sides by means of a clamping device, which is arranged for example in or in the region of the suction nozzles. In addition, it is possible that the thread through the two suction nozzles is in motion, especially if the spinning device continues to produce during the application of the method and the thread is sucked through the second suction nozzle.

Der zwischen den beiden Saugdüsen aufgespannte Faden wird von einer Fangeinrichtung erfasst, um den Faden zu fangen und anschließend auf die Hülse aufzuspulen. Die Fangeinrichtung greift in den gespannten Faden ein und bewegt ihn in Richtung auf die Hülse, sobald sich der Spulenteller dreht. Durch die beiden feststehenden Saugdüsen kann der Faden auf sehr einfache Art und Weise aufgespannt werden. Wird der Faden sodann mit der Spulstelle gekreuzt, so fängt die Fangeinrichtung den Faden und kann ihn anschließend derart auf der Hülse fixieren, dass der Faden auf die Hülse gewickelt wird. Der Ablauf kann sehr schnell erfolgen, da nur wenige Bewegungen erforderlich sind. Die Produktivität der Arbeitsstelle kann damit im Vergleich zu entsprechenden Verfahren aus dem Stand der Technik deutlich gesteigert werden.The spanned between the two suction nozzles thread is detected by a catching device to catch the thread and then wind on the sleeve. The catcher engages the tensioned thread and moves it toward the sleeve as soon as the spool plate rotates. Through the two fixed suction nozzles, the thread can be clamped in a very simple manner. If the thread is then crossed with the winding unit, the catching device intercepts the thread and can then fix it on the sleeve in such a way that the thread is wound onto the sleeve. The process can be very fast, since only a few movements are required. The productivity of the job can thus be significantly increased compared to corresponding methods of the prior art.

Wird zumindest die zweite Saugdüse beim Aufspulen und Anlegen des Fadens an die leere Hülse nicht bewegt, so ist eine deutliche Vereinfachung der Vorrichtung und insbesondere ein noch schnelleres Handhaben und Aufwickeln des Fadens auf die leere Hülse möglich. In einer besonders bevorzugten Ausführung der Erfindung sind beide Saugdüsen nicht bewegt, d. h. fest und stationär an der Arbeitsstelle angeordnet. Damit ist eine noch schnellere Fixierung des Fadens auf der leeren Hülse möglich. Der Verfahrensablauf ist hierdurch vereinfacht und schneller durchzuführen als beim Stand der TechnikIf at least the second suction nozzle is not moved when winding and applying the thread to the empty tube, then a significant simplification of the device and in particular an even faster handling and winding of the thread on the empty tube is possible. In a particularly preferred embodiment of the invention, both suction nozzles are not moved, that is, fixedly and stationarily arranged at the work site. This is an even faster Fixation of the thread on the empty sleeve possible. The procedure is thereby simplified and faster to carry out than in the prior art

In einer bevorzugten Ausführung der Erfindung sind der Spulenteller und/oder die Hülse zumindest ein Teil der Fangeinrichtung. Dabei wird der aufgespannte Faden mit dem Spulenteller und/oder der Hülse gekreuzt, um den Faden zu fangen und anschließend auf die Hülse aufzuspulen. Indem der Spulenteller und/oder die Hülse und der Faden einander kreuzen, kann der Spulenteller und/oder die Hülse den Faden ergreifen und dafür sorgen, dass der Faden anschließend auf die Hülse aufgewickelt wird. Hierfür kann der Spulenteller verschiedene, bekannte Merkmale aufweisen. Geeignet ist beispielsweise eine hakenförmige Ausbildung an dem Spulenteller, wobei der entsprechende Haken in den gespannten Faden eingreifen kann und ihn in Richtung auf die Hülse bewegt, sobald sich der Spulenteller dreht. Wird der Faden sodann mit der Spulstelle gekreuzt, so fängt der Haken den Faden und kann ihn anschließend derart auf der Hülse fixieren, dass der Faden auf die Hülse gewickelt wird. Alternativ kann der Faden auch mit der Hülse gekreuzt werden. Dabei wird er entweder bei entsprechend vorbereiteten, beispielsweise geschlitzten oder aufgerauten, Hülsen, auf dieser oder wiederum alternativ zwischen der Hülse und dem Spulenteller geklemmt und dabei gefangen.In a preferred embodiment of the invention, the reel plate and / or the sleeve are at least part of the catching device. In this case, the spanned thread is crossed with the reel plate and / or the sleeve to catch the thread and then wind on the sleeve. By the coil plate and / or the sleeve and the thread crossing each other, the coil plate and / or the sleeve can take the thread and ensure that the thread is then wound onto the sleeve. For this purpose, the reel plate may have various known features. It is suitable, for example, a hook-shaped design on the reel disc, wherein the corresponding hook can engage in the tensioned thread and moves it in the direction of the sleeve as soon as the reel disc rotates. If the thread is then crossed with the winding unit, the hook catches the thread and can then fix it on the sleeve in such a way that the thread is wound onto the sleeve. Alternatively, the thread can also be crossed with the sleeve. He is either clamped in appropriately prepared, for example, slotted or roughened sleeves, clamped on this or again alternatively between the sleeve and the coil plate and thereby caught.

Wird der Faden zwischen den beiden Saugdüsen mittels einer Führungseinrichtung geführt, so kann er in geeigneter Weise aufgespannt werden, um von dem Spulenteller sicher und einfach erfasst zu werden. Die Führungseinrichtung kann auch dafür vorgesehen sein, dass der Faden ausreichend gespannt ist, um ein Ergreifen des Fadens durch den Spulenteller sicher zu gewährleisten.If the thread is guided between the two suction nozzles by means of a guide device, then it can be clamped in a suitable manner in order to be reliably and easily grasped by the coil plate. The guide device can also be provided that the thread is sufficiently tensioned to ensure a secure gripping of the thread through the reel plate.

Wird der Faden mittels der Führungseinrichtung im Wesentlichen quer zum Spulenteller aufgespannt, so kann der Spulenteller, insbesondere wenn er am Umfang Haken aufweist, den Faden einfach und sicher erfassen.If the thread is clamped substantially transversely to the reel disc by means of the guide device, the reel disc, in particular if it has hooks on the circumference, can grasp the thread easily and securely.

Wird der Spulenteller in Richtung auf die Spulwalze abgesenkt oder die Führungseinrichtung in radialer Richtung auf den Spulenteller zu bewegt, damit der mittels der Führungseinrichtung unter einem Winkel, insbesondere im Wesentlichen quer zum Spulenteller aufgespannte Faden zwischen den beiden Saugdüsen mit dem Spulenteller gekreuzt wird, so ist ebenfalls ein schnelles und sicheres Erfassen des Fadens durch den Spulenteller und ein anschließendes Aufspulen des Fadens auf der Hülse gewährleistet. Besonders wenn der Spulenhalter abgesenkt wird, kann die Führungseinrichtung sehr einfach ausgebildet werden. In diesem Fall ist eine Beweglichkeit der Führungseinrichtung zum Zuführen des Fadens an den Spulenteller nicht erforderlich. Der Spulenteller bewegt sich mit dem Absenken der Hülse auf eine Spulwalze zum Antrieb der Hülse gleichzeitig auch auf die Führungseinrichtung und damit auf den darin gespannten Faden zu und ergreift diesen. Hierdurch ist es möglich, dass sowohl die beiden Saugdüsen als auch die Führungseinrichtung stationär ausgeführt werden können oder zumindest die Führungseinrichtung nach der Übergabe des Fadens lediglich geringfügig aus dem Bereich des Spulentellers heraus bewegt werden muss.If the reel plate is lowered in the direction of the winding roller or the guide device is moved in the radial direction toward the reel plate, so that the thread spanned by the guide device at an angle, in particular substantially transversely to the reel spool, is crossed between the two suction nozzles with the reel plate also ensures a fast and secure capture of the thread through the bobbin plate and a subsequent winding of the thread on the sleeve. Especially when the bobbin holder is lowered, the guide means can be formed very easily. In this case, a mobility of the guide means for supplying the thread to the bobbin plate is not required. The coil plate moves with the lowering of the sleeve on a winding roller for driving the sleeve at the same time also on the guide means and thus on the thread tensioned therein and seizes this. This makes it possible that both the two suction nozzles and the guide device can be performed stationary or at least the guide device after the transfer of the thread only slightly out of the range of the coil plate has to be moved out.

Wird die Führungseinrichtung nach dem Anlegen des Fadens auf die leere Hülse von den Spulenteller weg bewegt, so wird sichergestellt, dass die Führungseinrichtung beim Aufspulen des Fadens auf die Hülse bzw. die Bildung der Kreuzspule nicht behindert. Diese Bewegung erfolgt allerdings nach der Übergabe des Fadens an den Spulenteller und kann nach Beginn der Produktion des Fadens bzw. des Umspulens des Fadens erfolgen und führt somit zu keiner Verlängerung des Arbeitszyklus.If the guide device is moved away from the reel plate after the thread has been applied to the empty tube, it is ensured that the guide device does not hinder the winding of the thread on the sleeve or the formation of the cross-wound bobbin. However, this movement takes place after the transfer of the thread to the reel plate and can be done after the beginning of the production of the thread or the rewinding of the thread and thus does not lead to an extension of the duty cycle.

In einer vorteilhaften Ausführung der Erfindung wird der Faden von einer Hilfsspule einer Wartungseinrichtung oder von der zuvor an dieser Arbeitsstelle fertig gestellten Kreuzspule oder von der Spinnvorrichtung kommend zwischen die beiden Saugdüsen gebracht und von den beiden Saugdüsen eingesaugt. Damit befindet sich der Faden in den beiden Saugdüsen und kann in dem Abstand zwischen den beiden Saugdüsen entsprechend aufgespannt werden. Insbesondere wenn der Faden von der Spinnvorrichtung kommt und weiter produziert wird, kann dabei ein fliegender Wechsel der vollen Spule gegen eine leere Hülse erfolgen.In an advantageous embodiment of the invention, the thread from an auxiliary coil of a maintenance facility or from the previously at this workstation finished cross-wound bobbin or brought by the spinning device between the two suction nozzles and sucked by the two suction nozzles. Thus, the thread is in the two suction nozzles and can be clamped in accordance with the distance between the two suction nozzles. In particular, when the thread comes from the spinning device and is further produced, it can be done a flying change of the full bobbin against an empty sleeve.

Wird der Faden erst von der ersten Saugdüse und dann von der zweiten Saugdüse eingesaugt, so kann er mit vorbestimmten Längen in der jeweiligen Saugdüse positioniert werden.If the thread is first sucked in by the first suction nozzle and then by the second suction nozzle, then it can be positioned with predetermined lengths in the respective suction nozzle.

Bei der Verwendung des Fadens von einer Hilfsspule der Wartungseinrichtung ist es möglich ein Ansetzen des Fadens durchzuführen, auch wenn an der entsprechenden Arbeitsstelle kein Faden zur Verfügung steht. Dieses Verfahren ist somit sehr flexibel. Andererseits, wenn der Faden von der zuvor an dieser Arbeitsstelle fertig gestellten Kreuzspule kommend verwendet wird, ist die Arbeitsstelle in der Lage einen Wechsel der Spule auf eine leere Hülse durchzuführen, ohne dass eine entsprechende Wartungseinrichtung erforderlich wäre. Die Arbeitsstelle kann somit selbstständig, ohne auf eine Wartungseinrichtung angewiesen zu sein, das Spulen auf eine neue Hülse beginnen. Dabei wird der Faden von der fertig gestellten Kreuzspule abgenommen und in die erste und zweite Saugdüse, oder wenn er sich bereits in der ersten Saugdüse befindet nur in die zweite Saugdüse eingeführt. Nach dem Trennen des Fadens wird die volle Spule mit einer leeren Hülse ausgetauscht. Das in den beiden Saugdüsen befindliche Fadenstück kann sodann zum wieder Anspinnen bzw. zum Verbinden mit einem Faden eines zugeführten Kops und zum Anlegen auf die Hülse verwendet werden.When using the thread from an auxiliary coil of the maintenance device, it is possible to carry out a setting of the thread, even if at the corresponding job no thread is available. This method is thus very flexible. On the other hand, when the yarn is used coming from the previously completed at this work cross chuck, the job is able to perform a change of the coil to an empty shell, without a corresponding maintenance device would be required. The job can thus independently, without relying on a maintenance facility, start the coils on a new sleeve. In this case, the thread is removed from the finished cross-wound bobbin and inserted into the first and second suction nozzle, or if it is already in the first suction nozzle only in the second suction nozzle. After separating the thread, the full bobbin is replaced with an empty tube. The piece of thread located in the two suction nozzles can then be used for re-spinning or for connecting to a thread of a supplied cop and for applying to the sleeve.

Wird der Faden von der Wartungseinrichtung in die beiden Saugdüsen eingelegt, so wird der konstruktive Aufwand der einzelnen Arbeitsstellen der Maschine reduziert. Dieser relativ seltene Eingriff kann von der Wartungseinrichtung durchgeführt werden, welche alle erforderlichen Handhabungseinrichtungen aufweist, ohne dass diese an jeder Arbeitsstelle stets vorhanden sein müssen. Wird der Faden von einer Wartungseinrichtung in die beiden Saugdüsen eingelegt, so kann ein gezieltes Zuführen des Fadens von der Hilfsspule oder von der zuvor an dieser Arbeitsstelle fertig gestellten Kreuzspule an die Führungseinrichtung erfolgen, um das ordnungsgemäße Ergreifen durch die Fangeinrichtung sicherzustellen.If the thread is inserted by the maintenance device in the two suction nozzles, the design complexity of the individual jobs of the machine is reduced. This relatively rare intervention can be made by the service facility be carried out, which has all the necessary handling facilities, without having to always be present at each workstation. If the thread is inserted into the two suction nozzles by a maintenance device, a targeted feeding of the thread from the auxiliary coil or from the cheese previously completed at this point of operation to the guide device can take place in order to ensure proper gripping by the catching device.

Nachdem der Faden auf die leere Hülse angelegt wurde, wird der Faden getrennt und das in die zweite Saugdüse ragende Fadenende abgesaugt. Der Faden wird sodann auf die Hülse aufgewickelt. Damit wird sichergestellt, dass kein Fadenende über die Spule hinaus ragt und hierdurch zu Beschädigungen der Spule führen könnte. In einer bevorzugten Ausführung wird der Faden während des Aufspulens auf die Kreuzspule durch die erste Saugdüse hindurch geführt.After the thread has been applied to the empty sleeve, the thread is separated and sucked the projecting into the second suction nozzle end of the thread. The thread is then wound onto the sleeve. This ensures that no thread end protrudes beyond the bobbin, which could damage the bobbin. In a preferred embodiment, the thread is guided through the first suction nozzle during winding onto the cross-wound bobbin.

Wird der Faden nach dem Anlegen auf die leere Hülse mittels der Führungseinrichtung changiert oder an eine Changiereinrichtung übergeben, so kann anschließend die normale Bewicklung der Spule erfolgen. Wird der Faden mittels der Führungseinrichtung changiert, d. h. die Führungseinrichtung ist Teil der Changiereinrichtung, so führt dies zu einer baulich sehr einfachen Ausführung der Erfindung. Eine Übergabe der Führungseinrichtung an die Changiereinrichtung ist dadurch nicht erforderlich. Dies kann beispielsweise so erfolgen, dass die Führungs- bzw. Changiereinrichtung in der Lage ist über den normalen Changierweg, der für die Bewicklung der Spule nötig ist, hinaus bewegt zu werden, um den Faden zwischen den beiden Saugdüsen zu spannen. Sobald die normale Bewicklung der Spule erfolgt, bewegt sich der Changierfadenführer innerhalb des Changierweges der Kreuzspule.If the thread is changed after application to the empty shell by means of the guide device or transferred to a traversing device, the normal winding of the coil can subsequently take place. If the thread is oscillated by means of the guide device, d. H. the guide device is part of the traversing device, this leads to a structurally very simple embodiment of the invention. A transfer of the guide device to the traversing device is not required. This can be done, for example, so that the guiding or traversing device is able to be moved beyond the normal traversing path, which is necessary for the winding of the coil, to stretch the thread between the two suction nozzles. Once the normal winding of the bobbin, the traversing yarn guide moves within the traverse path of the cheese.

Alternativ ist es auch möglich, dass die Führungseinrichtung und die Changiereinrichtung separate Bauteile sind. Hierdurch ist eine Übergabe des Fadens von der Führungseinrichtung auf die Changiereinrichtung erforderlich.Alternatively, it is also possible that the guide device and the traversing device are separate components. As a result, a transfer of the thread from the guide device to the traversing device is required.

Dies kann durch eine entsprechende Geometrie der Führungseinrichtung erfolgen, d. h. dass der Faden aus der Führungseinrichtung herausfällt, sobald er getrennt wurde. Alternativ kann durch eine entsprechende Bewegung der Führungseinrichtung der Faden auf die Changiereinrichtung abgeworfen werden.This can be done by a corresponding geometry of the guide means, d. H. that the thread falls out of the guide device as soon as it has been separated. Alternatively it can be dropped onto the traversing device by a corresponding movement of the guide means of the thread.

Eine erfindungsgemäße Arbeitsstelle einer Spinn- und/oder Spulmaschine verfügt über eine Spinnvorrichtung zur Produktion eines Fadens bzw. einen Kops zur Zulieferung eines Fadens sowie eine Spulvorrichtung zur Herstellung einer Kreuzspule auf einer Hülse. Die Spulvorrichtung weist einen schwenkbar gelagerten Spulenhalter mit Spulenteller zur Aufnahme der Hülse und zum Fangen des Fadens, eine angetriebene Spulwalze zum Drehen der Hülse bzw. der Spule sowie eine Fadenchangiereinrichtung auf. Die Arbeitsstelle ist mit einer ersten, auf den Spulenumfang gerichteten Saugdüse und weiterhin mit einer zweiten, auf der von der Spule Kreuzspule abgewandten Seite des Spulentellers angeordneten und im Wesentlichen entgegen der ersten Saugdüse gerichtet und von dieser beabstandeten Saugdüse ausgestattet. Erfindungsgemäß sind die beiden Saugdüsen derart zueinander angeordnet, dass der in den beiden Saugdüsen befindliche Faden zum Anlegen an eine leere Hülse zwischen den beiden Saugdüsen mittels Unterdruck in zumindest der zweiten Saugdüse so aufgespannt werden kann, dass er von einer Fangeinrichtung erfasst werden kann. Hierdurch kann der Faden gefangen und anschließend auf die Hülse aufgespult werden.A workstation according to the invention of a spinning and / or winding machine has a spinning device for producing a thread or a cop for supplying a thread and a winding device for producing a cross-wound bobbin on a sleeve. The winding device has a pivotally mounted reel holder with reel disc for receiving the sleeve and for catching the thread, a driven winding roller for rotating the sleeve or the reel, and a thread-changing device. The work station is arranged with a first, directed onto the coil circumference suction nozzle and further with a second, on the side facing away from the spool cheese from the side of the reel disc and directed substantially opposite to the first suction nozzle and spaced from this suction nozzle. According to the invention, the two suction nozzles are arranged relative to each other such that the thread located in the two suction nozzles can be clamped for application to an empty sleeve between the two suction nozzles by means of negative pressure in at least the second suction nozzle so that it can be detected by a catching device. As a result, the thread can be caught and then wound on the sleeve.

Durch die erfindungsgemäßen Anordnungen der Saugdüsen wird der Faden zwischen den Saugdüsen gespannt. Die beiden Saugdüsen saugen in entgegengesetzter Richtung den Faden an, so dass dieser zwischen den beiden Saugdüsen gespannt ist. Alternativ ist es auch möglich, dass der Faden im Bereich der ersten Saugdüse geklemmt ist und durch die zweite Saugdüse angesaugt wird, oder umgekehrt auch in den oder im Bereich der beiden Saugdüsen geklemmt ist. Auch hierdurch entsteht eine Spannung auf dem Faden. Durch die Fangeinrichtung wird der Faden ergriffen und kann auf die Hülse aufgewickelt werden.The inventive arrangements of the suction nozzles, the thread between the suction nozzles is tensioned. The two suction nozzles suck in the opposite direction to the thread, so that it is stretched between the two suction nozzles. Alternatively, it is also possible that the thread is clamped in the region of the first suction nozzle and is sucked in by the second suction nozzle, or vice versa is clamped in or in the region of the two suction nozzles. This also creates a tension on the Thread. By catching the thread is gripped and can be wound up on the sleeve.

Ganz besonders vorteilhaft ist es, wenn zumindest die zweite Saugdüse vorzugsweise beide Saugdüsen unbeweglich angeordnet sind. Die beiden stationär angeordneten Saugdüsen sorgen dabei für eine sehr einfache Ausführung der erfindungsgemäßen Arbeitsstelle. Einrichtungen zum Bewegen und zum Führen der Saugdüsen sind nicht erforderlich. Beide Saugdüsen können an der Arbeitsstelle fixiert sein und der Faden wird durch die beiden Saugdüsen hindurch geführt. Selbstverständlich ist es aber auch möglich, dass eine oder beide Saugdüsen beweglich, bspw. verschwenkbar oder verschiebbar ausgebildet sind.It is particularly particularly advantageous if at least the second suction nozzle, preferably both suction nozzles, are arranged immovably. The two stationary suction nozzles provide for a very simple execution of the job according to the invention. Facilities for moving and guiding the suction nozzles are not required. Both suction nozzles can be fixed at the workplace and the thread is passed through the two suction nozzles. Of course, it is also possible that one or both suction nozzles are designed to be movable, for example pivotable or displaceable.

In einer bevorzugten Ausführung der Erfindung wird das zwischen den beiden Saugdüsen befindliche Fadenstück mit dem Spulenteller und/oder der Hülse gekreuzt. Der Spulenteller und/oder die Hülse sind dabei zumindest ein Teil der Fangeinrichtung und der aufgespannte Faden kann so gefangen und anschließend auf die Hülse aufgespult werden. Dadurch kann der Faden gezielt in den Bereich des Spulentellers oder der Hülse oder umgekehrt der Spulenteller oder die Hülse in dem Bereich des gespannten Fadens gebracht werden. Der Faden kann hierdurch erfasst und auf die Hülse aufgewickelt werden.In a preferred embodiment of the invention, the piece of thread located between the two suction nozzles is crossed with the reel plate and / or the sleeve. The reel disc and / or the sleeve are at least part of the catching device and the spanned thread can be caught and then wound onto the sleeve. As a result, the thread can be selectively brought into the region of the reel plate or the sleeve or, conversely, the reel plate or the sleeve in the region of the tensioned thread. The thread can thereby be detected and wound up on the sleeve.

Ist zwischen den beiden Saugdüsen eine Führungseinrichtung zum Führen des Fadens vorgesehen, so kann der Faden im Wesentlichen quer zum Spulenteller angeordnet werden. Die Führungseinrichtung sorgt dafür, dass der Kreuzungswinkel zwischen der Fangeinrichtung, beispielsweise dem Spulenteller, und dem aufgespannten Faden so ist, dass entsprechend der Fangeinrichtung der Faden ideal positioniert ist. Vorzugsweise hat der Spulenteller einen gezahnten Umfang, wobei die Zähne in den aufgespannten Faden eingreifen können und diesen zur Hülse hin bringen. Alternativ zu solchen Zähnen kann auch eine längs orientierte Vertiefung an dem Spulenteller, der Hülse oder zwischen der Hülse und dem Spulenteller vorgesehen sein, in welcher der Faden geklemmt wird. In diesem Falle ist es vorteilhaft, wenn der Faden weitgehend parallel zum Spulenteller ausgerichtet ist. Der Kreuzungswinkel ist in diesem Falle sehr gering.If a guide device for guiding the thread is provided between the two suction nozzles, then the thread can be arranged essentially transversely to the reel plate. The guide device ensures that the crossing angle between the catching device, for example the reel plate, and the opened thread is such that, according to the catching device, the thread is ideally positioned. Preferably, the bobbin plate has a toothed circumference, wherein the teeth can engage in the tensioned thread and bring this towards the sleeve. As an alternative to such teeth can also be a longitudinally oriented recess on the reel disc, the Sleeve or be provided between the sleeve and the reel disc, in which the thread is clamped. In this case, it is advantageous if the thread is aligned substantially parallel to the reel plate. The crossing angle is very low in this case.

In einer bevorzugten Ausführung der Erfindung ist die Führungseinrichtung in radialer Richtung auf den Spulenteller zu und/oder von diesem weg bewegbar angeordnet. Die Führungseinrichtung kann damit den aufgespannten Faden entweder in Richtung auf den Spulenteller hin bewegen oder nach dem Ergreifen des Fadens aus dem Bereich des Spulentellers heraus bewegt werden, um dem späteren Aufspulen des Fadens auf der Kreuzspule nicht hinderlich zu sein.In a preferred embodiment of the invention, the guide device is arranged in the radial direction on the reel disc and / or movable away therefrom. The guide device can thus move the clamped thread either in the direction of the reel plate or moved out of the region of the reel disc after gripping the thread so as not to hinder the subsequent winding of the thread on the cross-wound bobbin.

Besonders vorteilhaft ist es, wenn die Führungseinrichtung an der ersten Saugdüse bzw. dessen Gehäuse angeordnet ist. Die Führungseinrichtung kann in diesem Falle exakt in Bezug auf die Kreuzspule, auf deren Spulenumfang die erste Saugdüse gerichtet ist, angeordnet sein.It is particularly advantageous if the guide device is arranged on the first suction nozzle or its housing. The guide device can be arranged in this case exactly with respect to the cross-wound bobbin, on the coil circumference of which the first suction nozzle is directed.

Ist die Führungseinrichtung Teil einer bewegbaren Mündung der ersten Saugdüse, so kann die Zuführung des Fadens zu der Fangeinrichtung bzw. das Wegbewegen der Führungseinrichtung nach der Übergabe des Fadens an die Fangeinrichtung sehr einfach realisiert werden.If the guide device is part of a movable mouth of the first suction nozzle, then the feeding of the thread to the catching device or the moving away of the guide device after the transfer of the thread to the catching device can be realized very easily.

Ist die Führungseinrichtung hakenförmig ausgebildet, so kann der Faden auf sehr einfache Weise um den oder die Haken der Führungseinrichtung gelegt werden und von zumindest der zweiten Saugeinrichtung angesaugt und dadurch gespannt werden.If the guide device is hook-shaped, then the thread can be placed in a very simple manner around the hook or hooks of the guide device and can be sucked in by at least the second suction device and thereby tightened.

Um eine besonders einfache Ausführung der Erfindung zu schaffen, ist es vorteilhaft, wenn die Führungseinrichtung gleichzeitig ein Changierfadenführer ist. In diesem Falle wird der Changierfadenführer aus dem Changierweg für die Kreuzspule heraus geführt und dient dort als Führungseinrichtung für den Faden.In order to provide a particularly simple embodiment of the invention, it is advantageous if the guide device is at the same time a traversing yarn guide. In this case, the traversing yarn guide is from the traverse path led out for the cheese out and serves as a guide device for the thread.

Ist eine Wartungseinrichtung vorgesehen, die zum Einlegen des Fadens in die beiden Saugdüsen dient, so kann beispielsweise auch von einer Hilfsspule ein Faden zugeführt werden, welche sich auf der Wartungseinrichtung befindet. Das Anspinnen und Ansetzen des Fadens kann dadurch erfolgen, ohne dass sich ein entsprechend benötigtes Fadenende an der Arbeitsstelle befindet. Die Wartungseinrichtung, welche entlang einer Vielzahl von Arbeitsstellen patrouilliert, führt dieses Fadenende von der mitgeführten Hilfsspule der Arbeitsstelle bzw. den Saugdüsen zu.If a maintenance device is provided which serves to insert the thread into the two suction nozzles, it is also possible, for example, to supply a thread from an auxiliary coil which is located on the maintenance device. The piecing and setting of the thread can be done without a correspondingly required thread end is located at the workplace. The maintenance device, which patrols along a plurality of jobs, leads this thread end of the entrained auxiliary coil of the job or the suction nozzles.

Ist an der Arbeitsstelle eine Trennvorrichtung angeordnet, um den Faden nach dem Anlegen auf die leere Hülse zu trennen, so kann das abgetrennte Fadenende durch die zweite Saugdüse abgesaugt werden. An der Kreuzspule befindet sich kein überhängendes Fadenende, welches zur Beschädigung der Kreuzspule führen könnte.If a separating device is arranged at the work station in order to separate the thread after it has been applied to the empty sleeve, then the severed thread end can be sucked out through the second suction nozzle. There is no overhanging thread end on the cross-wound bobbin, which could damage the cross-wound bobbin.

In den Figuren 1a bis 1c ist eine Seitenansicht einer skizzierten Arbeitsstelle einer Spinn-/Spulmaschine, beispielsweise eine Rotorspinnmaschine oder eine Luftspinnmaschine, dargestellt, bei welcher zwei Saugdüsen im Schnitt gezeigt sind. Die folgenden Ausführungsbeispiele beziehen sich jeweils auf eine Fangeinrichtung, die mittels eines gezahnten Spulentellers ausgestattet ist. Eine Fangeinrichtung, die sich auf der Hülse oder zwischen der Hülse und dem Spulenteller befindet, arbeitet analog zu der folgenden Beschreibung. Die Positionierung des Fadens in Bezug auf die Fangeinrichtung kann dabei so abgeändert sein, dass die entsprechende Fangeinrichtung den Faden gut und zuverlässig erfassen kann.In the FIGS. 1a to 1c is a side view of a sketched job of a spinning / winding machine, such as a rotor spinning machine or an air-spinning machine, shown, in which two suction nozzles are shown in section. The following embodiments each relate to a catching device, which is equipped by means of a toothed coil plate. An interceptor located on the sleeve or between the sleeve and the reel disc operates analogously to the following description. The positioning of the thread with respect to the catching device can be modified so that the corresponding catching device can detect the thread well and reliably.

In Figur 1a ist die Spinn-/Spulmaschine während der Produktion gezeigt. In einer Spinnvorrichtung 1 wird ein Faden 2 produziert und mittels angetriebener Abzugswalzen 3 aus der Spinnvorrichtung 1 abgezogen. Der Faden 2 läuft durch eine Öffnung 4 einer ersten Saugdüse 5 durch diese erste Saugdüse 5 hindurch und gelangt zu einer Spulvorrichtung 6. Die Spulvorrichtung 6 weist eine Spule 7 auf, auf welche der Faden 2 aufgewickelt wird. Die Spule 7 ist in einem Spulenhalter 8 gehalten. Der Spulenhalter 8 ist schwenkbar gemäß Doppelpfeilrichtung gelagert und passt sich dem aktuellen Durchmesser der Spule 7 an. Außerdem ist er in der Lage die Spule 7 bzw. die in folgenden Figuren dargestellte Hülse 18 bei Bedarf anzuheben oder abzusenken. An dem Spulenhalter 8, welcher beidseitig die Spule 7 bzw. Hülse 18 umgreift, ist ein Spulenteller 9 angeordnet, welcher Zähne 10 aufweist. Die Zähne 10 dienen zum Fangen des Fadens 2, wie später noch ausführlich beschrieben wird. Zur Drehung der Spule 7 in Pfeilrichtung liegt diese auf einer Spulwalze 11 auf, welche angetrieben ist. Der Faden 2 befindet sich in einem Fadenführer 11, welcher vor der Spule 7 hin und her changiert und den Faden 2 kreuzweise auf die Spule 7 aufwickelt.In FIG. 1a the spinning / winding machine is shown during production. In a spinning device 1, a yarn 2 is produced and withdrawn from the spinning device 1 by means of driven take-off rolls 3. The yarn 2 passes through an opening 4 of a first suction nozzle 5 through this first suction nozzle 5 and passes to a winding device 6. The winding device 6 has a coil 7, on which the yarn 2 is wound. The coil 7 is held in a coil holder 8. The coil holder 8 is pivotally mounted according to the double arrow direction and adapts to the current diameter of the coil 7. In addition, he is able to raise or lower the coil 7 or the sleeve 18 shown in the following figures as needed. On the coil holder 8, which surrounds the coil 7 or sleeve 18 on both sides, a coil plate 9 is arranged, which has teeth 10. The teeth 10 serve to catch the thread 2, as will be described in detail later. For rotation of the spool 7 in the direction of the arrow, it rests on a winding roller 11, which is driven. The thread 2 is located in a yarn guide 11, which oscillates back and forth in front of the bobbin 7 and winds the yarn 2 crosswise on the bobbin 7.

Seitlich der Spule 7 ist eine zweite Saugdüse 12 angeordnet, welche der ersten Saugdüse 5 entgegen gerichtet ist. Die beiden Mündungen der erste Saugdüse 5 und der zweite Saugdüse 12 stehen einander im Wesentlichen gegenüber, auch wenn sie bei Blickrichtung auf die Wickelfläche der Spule 7 seitlich zueinander versetzt sein können. Wie später noch beschrieben wird, wird entsprechend dem erfindungsgemäßen Verfahren der Faden 2 zwischen den beiden Mündungen aufgespannt.The side of the coil 7, a second suction nozzle 12 is arranged, which is directed opposite to the first suction nozzle 5. The two mouths of the first suction nozzle 5 and the second suction nozzle 12 are substantially opposite each other, even if they can be laterally offset from each other when viewed on the winding surface of the coil 7. As will be described later, according to the inventive method, the thread 2 is clamped between the two mouths.

Im Bereich der Abzugswalzen 3 ist ein Halter 13 vorgesehen, welcher drehbar gelagert ist. An dem Halter 13 sind eine Abdichtung 14 und eine Öse 15 angeordnet. Die Abdichtung 14 ist dafür vorgesehen die Öffnung 4 der ersten Saugdüse 5 abzudichten, während sich die Öse 15 innerhalb der ersten Saugdüse 5 befindet bzw. wenn die erste Saugdüse 5 an der Mündung eine Saugkraft zum Anziehen oder Halten des Fadens 2 aufweisen soll.In the area of take-off rolls 3, a holder 13 is provided, which is rotatably mounted. On the holder 13, a seal 14 and an eyelet 15 are arranged. The seal 14 is intended to seal the opening 4 of the first suction nozzle 5, while the eyelet 15 is within the first suction nozzle 5 or when the first suction nozzle 5 at the mouth should have a suction force for attracting or holding the thread 2.

Die erste Saugdüse 5 ist an eine erste Absaugung A1 und die zweite Saugdüse 12 an eine zweite Absaugung A2 angeschlossen. Beide Absaugungen A1 und A2 können unabhängig voneinander ein- und ausgeschaltet werden. In der Darstellung der Figur 1a sind die beiden Absaugungen abgeschaltet, da der Faden 2 direkt von der Spinnvorrichtung 1 durch die Öffnung 4 und den oberen Teil der ersten Saugdüse 5 zur Spulvorrichtung 6 verläuft und dort auf die Spule 7 aufgewickelt wird. Eine Saugkraft der ersten Saugdüse 5 auf den Faden 2 ist in diesem Zustand nicht erforderlich.The first suction nozzle 5 is connected to a first suction A1 and the second suction nozzle 12 to a second suction A2. Both aspirators A1 and A2 can be switched on and off independently of each other. In the presentation of the FIG. 1a the two suction devices are switched off, since the yarn 2 runs directly from the spinning device 1 through the opening 4 and the upper part of the first suction nozzle 5 to the winding device 6 and is wound there on the spool 7. A suction force of the first suction nozzle 5 on the yarn 2 is not required in this state.

In der Darstellung der Figur 1b ist im Vergleich zu Figur 1 a der Halter 13 nach oben geschwenkt und verschließt mit der Abdichtung 14 die Öffnung 4. Beide Absaugungen A1 und A2 sind eingeschaltet. Der Faden 2 befindet sich mit einem Ende in der ersten Saugdüse 5 und mit dem anderen Ende in der zweiten Saugdüse 12. Der Faden 2 verläuft dabei durch die Öse 15 des Halters 13. Der Faden 2 in Figur 1b stammt dabei beispielsweise von einer Hilfsspule, welche von einem nicht dargestellten Wartungswagen an die entsprechende Arbeitsstelle gebracht wurde. Der Wartungswagen hat sodann mittels entsprechender Handhabungselemente ein Fadenstück in die beiden Saugdüsen 5 und 12 eingeführt. Der Faden 2 befindet sich dabei nicht mehr in dem Fadenführer 16 und wird somit nicht mehr changiert. Das Einlegen des Fadens 2 in die beiden Saugdüsen 5 und 12 kann alternativ auch von Hand erfolgen.In the presentation of the FIG. 1b is compared to FIG. 1 a, the holder 13 is pivoted upward and closes with the seal 14, the opening 4. Both suction A1 and A2 are turned on. The thread 2 is located with one end in the first suction nozzle 5 and with the other end in the second suction nozzle 12. The thread 2 extends through the eye 15 of the holder 13. The thread 2 in FIG. 1b originates, for example, from an auxiliary coil, which was brought by a maintenance car, not shown, to the appropriate job. The maintenance trolley has then introduced by means of appropriate handling elements a piece of thread in the two suction nozzles 5 and 12. The thread 2 is no longer in the yarn guide 16 and is therefore no longer shades. The insertion of the thread 2 in the two suction nozzles 5 and 12 may alternatively be done by hand.

In Figur 1c ist der Halter 13 wieder nach unten geschwenkt und hat das eine Fadenende, welches sich zuvor in der ersten Saugdüse 5 befunden hatte, durch die Öffnung 4 hindurch gezogen und zwischen die beiden Abzugswalzen 3 eingelegt. Der Faden 2 ist somit durch die Abzugswalzen 3 fixiert. Durch eine Drehung der Abzugswalzen 3 kann der Faden 2 in seiner Längsrichtung bewegt werden. Das andere Ende des Fadens 2 befindet sich weiterhin in der zweiten Absaugung 12 und wird durch die Saugkraft in dieser Saugdüse 12 gehalten.In Figure 1c the holder 13 is pivoted back down and has the one thread end, which had previously been in the first suction nozzle 5, pulled through the opening 4 and inserted between the two take-off rolls 3. The thread 2 is thus fixed by the take-off rolls 3. By a rotation of the take-off rolls 3, the thread 2 can be moved in its longitudinal direction. The other end of the thread 2 is still in the second suction 12 and is held by the suction force in this suction nozzle 12.

Die Spule 7 kann bereits in dem Verfahrensschritt gemäß Figur 1b oder auch erst in oder nach dem Verfahrensschritt gemäß Figur 1c gegen eine leere Hülse 18 gewechselt werden.The coil 7 can already in the method step according to FIG. 1b or only in or after the method step according to Figure 1c be changed against an empty sleeve 18.

In der weiteren Beschreibung wird das erfindungsgemäße Verfahren näher beschrieben. Die Figuren 2a bis 2f sowie 3a bis 3h zeigen eine Draufsicht auf die Spulvorrichtung 6.In the further description of the inventive method will be described in more detail. The FIGS. 2a to 2f and FIGS. 3 a to 3 h show a plan view of the winding device 6.

Die Darstellung der Figur 2a entspricht im Wesentlichen der Situation, wie sie in Figur 1b dargestellt ist. Die beiden Absaugungen A1 und A2 sind eingeschaltet und der Faden 2 befindet sich mit zwei Enden sowohl in der ersten Saugdüse 5 als auch in der zweite Saugdüse 12.The presentation of the FIG. 2a is essentially the same as the situation in FIG. 1b is shown. The two suction A1 and A2 are turned on and the thread 2 is located with two ends in both the first suction nozzle 5 and in the second suction nozzle 12th

Eine Hülse 18 ist zwischen zwei Spulentellern 9 gehalten. Der Spulenteller 9 weist am Umfang Zähne 10 auf, mit welchen der Faden 2 gefangen werden kann. Der gegenüberliegende Spulenteller 9' weist dagegen keine Zähne 10 auf, da an dieser Stelle der Faden 2 nicht gefangen werden muss. Die Hülse 18 ist von der ersten Saugdüse 5 so weit entfernt, dass der Spulenteller 9 nicht in einen Bereich eingreift, in welchem der Faden 2 verläuft. Hierzu ist die Hülse 18 mit dem hier aus Gründen der besseren Übersichtlichkeit nicht dargestellten Spulenhalter 8 von der Spulwalze 11 abgehoben.A sleeve 18 is held between two coil plates 9. The reel plate 9 has on the circumference of teeth 10, with which the thread 2 can be caught. The opposite reel disc 9 ', however, has no teeth 10, since at this point the thread 2 does not have to be caught. The sleeve 18 is so far away from the first suction nozzle 5 that the reel plate 9 does not engage in a region in which the yarn 2 extends. For this purpose, the sleeve 18 is lifted from the winding roller 11 with the coil holder 8, not shown here for reasons of clarity.

Der Faden 2 verläuft durch die erste Saugdüse 5 über einen ersten Haken 19 zu einem zweiten Haken 20 in die zweite Saugdüse 12 hinein. Er ist nicht in dem Fadenführer 16 (Figur 1a) geführt. Der erste Haken 19 und der zweite Haken 20 sind Teil einer Führungseinrichtung 22, welche den Faden 2 zum wieder Anlegen an die Hülse 18 führt. Die beiden Haken 19 und 20 sind an einer Seite einer Platte 23 befestigt, welche sich wiederum in diesem Ausführungsbeispiel an dem Gehäuse der ersten Saugdüse 5 befindet. Die Platte 23 kann eine Art Mündungsstück der ersten Saugdüse 5 sein, welche weitere Funktionen, wie beispielsweise das Ansaugen eines Fadenendes auf einer Spule 7 oder das Abheben des Fadens 2 aus dem Fadenführer 16 haben kann.The thread 2 passes through the first suction nozzle 5 via a first hook 19 to a second hook 20 in the second suction nozzle 12 into it. He is not in the thread guide 16 ( FIG. 1a ) guided. The first hook 19 and the second hook 20 are part of a guide device 22, which guides the thread 2 for reapplication to the sleeve 18. The two hooks 19 and 20 are attached to one side of a plate 23, which in turn is in this embodiment on the housing of the first suction nozzle 5. The plate 23 may be a kind of mouthpiece of the first suction nozzle 5, which may have other functions, such as the suction of a thread end on a spool 7 or the lifting of the thread 2 from the yarn guide 16.

Der Faden 2 ist wie bereits oben beschrieben zwischen den beiden Haken 19 und 20 aufgespannt. Der erste Haken 19 ist dabei weniger gebogen als der zweite Haken 20. Die Begründung hierfür ist, dass der Faden 2 zu einem späteren Zeitpunkt des Verfahrensablaufes über den ersten Haken 19 abrutschen soll, um in den Fadenführer 16 eingeführt werden zu können. Der zweite Haken 20 hingegen ist stärker gebogen, um sicherzustellen, dass der Faden 2 in die Mündung der zweiten Saugdüse 12 eingeführt werden kann. Selbstverständlich sind auch andere Ausführungen der Haken 19 und 20 möglich, je nach den Gegebenheiten an den einzelnen Spulvorrichtungen 6. Der erste Haken 19 und der zweite Haken 20 sind so weit voneinander beabstandet, dass der Spulenteller 9 zwischen die beiden Haken 19 und 20 eingreifen kann und dort den Faden 2 ergreifen kann.The thread 2 is spanned as already described above between the two hooks 19 and 20. The first hook 19 is less curved than the second hook 20. The reason for this is that the thread 2 should slip off at a later time of the procedure over the first hook 19 in order to be introduced into the thread guide 16 can. The second hook 20, however, is bent more to ensure that the thread 2 can be inserted into the mouth of the second suction nozzle 12. Of course, other embodiments of the hooks 19 and 20 are possible, depending on the circumstances of the individual winding devices 6. The first hook 19 and the second hook 20 are so far apart from each other, that the reel disc 9 can engage between the two hooks 19 and 20 and can take the thread 2 there.

Das Ergreifen des Fadens 2 durch die Zähne 10 des Spulentellers 9 ist in Figur 2b dargestellt. Hier wird die Hülse 18 auf die Spulwalze 11 aus Figur 1 a abgesenkt und beginnt sich zu drehen. Die Zähne 10 des Spulentellers 9 befinden sich im Bereich zwischen den beiden Haken 19 und 20 und erfassen den dazwischen aufgespannten Faden 2. Der Faden 2 ist dabei weiterhin in der zweiten Saugdüse 12 angesaugt. Das andere Ende des Fadens 2 befindet sich mittlerweile zwischen den beiden Abzugswalzen 3 gemäß Figur 1 c. Alternativ wäre es auch möglich durch eine weiterhin eingeschaltete Absaugung A1 der ersten Saugdüse 5 den Faden 2 an diesem Ende gespannt zu halten.The gripping of the thread 2 by the teeth 10 of the reel disc 9 is shown in FIG. 2b. Here, the sleeve 18 on the winding roller 11 FIG. 1 a lowered and starts to turn. The teeth 10 of the reel disc 9 are in the area between the two hooks 19 and 20 and detect the thread 2 clamped therebetween. The thread 2 is still sucked into the second suction nozzle 12. The other end of the thread 2 is meanwhile between the two take-off rolls 3 according to FIG. 1 c. Alternatively, it would also be possible to keep the thread 2 stretched at this end by means of a continued suction A1 of the first suction nozzle 5.

Figur 2c zeigt den Faden 2, wie er von den Zähnen 10 des Spulentellers 9 erfasst wurde, auf die Hülse 18 gezogen und dort zwischen der Hülse 18 und dem Spulenteller 9 geklemmt wird. Der Faden 2 läuft dabei immer noch über die beiden Haken 19 und 20. Wenn er am unteren Ende in den Abzugswalzen 3 fixiert ist, wird das andere Fadenende aus der zweite Absaugung 12 entgegen der Absaugkraft der Absaugung A2 herausgezogen und stellt die zur Klemmung an der Hülse 18 erforderliche Länge zur Verfügung. Alternativ kann der erforderliche Faden 2 auch durch die Lieferung aus den Abzugswalzen 3 zur Verfügung gestellt werden. Figure 2c shows the thread 2, as it was detected by the teeth 10 of the reel plate 9, pulled onto the sleeve 18 and clamped there between the sleeve 18 and the reel plate 9. The thread 2 is still running over the two hooks 19 and 20. If it is fixed at the lower end in the take-off rollers 3, the other end of the thread is pulled out of the second suction 12 against the suction force of the suction A2 and provides for clamping to the Sleeve 18 required length available. Alternatively, the required thread 2 can also be made available by the delivery from the take-off rolls 3.

Gemäß Figur 2d wird das Fadenende, welches nicht zum Klemmen an der Hülse 18 erforderlich ist mittels einer Trenneinrichtung 24, welche hier symbolisch als Schere dargestellt ist, getrennt. Das überschüssige Fadenende wird durch die Absaugung A2 der zweiten Saugdüse 12 abgesaugt. Der Faden 2 läuft nunmehr nur noch über den ersten Haken 19 auf die Hülse 18.According to Figure 2d the thread end, which is not required for clamping on the sleeve 18 by means of a separator 24, which is symbolically shown here as a scissors, separated. The excess thread end is sucked through the suction A2 of the second suction nozzle 12. The thread 2 now runs only on the first hook 19 on the sleeve 18th

Wie aus Figur 2e ersichtlich ist, wird sodann der Faden 2 an den Fadenführer 16, welcher vor der Hülse 18 hin und her changiert, übergeben. Der Fadenführer 16 war bislang außerhalb des Eingriffsbereichs des Fadens 2 positioniert, um die vorherigen Arbeitsschritte nicht zu behindern. Bei der Übergabe rutscht der Faden 2 von dem Haken 19 herunter. Die Übergabe kann beispielsweise durch eine Bewegung der Platte 23 erfolgen, wodurch der Faden 2 von dem Haken 19 herunterrutscht oder aber auch durch die Bewegung des Fadenführers 16, welcher in den Verlauf des Fadens 2 gefahren wird und dort höhere Mitnahmekräfte auf den Faden 2 ausübt als der Haken 19 Rückhaltekräfte aufweist.How out FIG. 2e it can be seen, then the thread 2 to the yarn guide 16, which oscillates back and forth before the sleeve 18, passed. The thread guide 16 was previously positioned outside the engagement area of the thread 2, so as not to hinder the previous steps. When passing the thread 2 slips down from the hook 19. The transfer can be done for example by a movement of the plate 23, whereby the thread 2 slips down from the hook 19 or by the movement of the thread guide 16, which is driven in the course of the thread 2 and there higher driving forces on the thread 2 exerts the hook 19 has retaining forces.

Der Faden 2 beginnt nun auf der Hülse 18 hin und her zu changieren, wie aus Figur 2f ersichtlich ist. Um den weiteren Spulenaufbau nicht zu behindern wird die Platte 23 mit den Haken 19 und 20 von der Hülse 18 weg bewegt. Hierfür bietet es sich an, dass das Gehäuse der ersten Saugdüse 5 als Führung dient.The thread 2 now begins to oscillate on the sleeve 18 back and forth, as from FIG. 2f is apparent. In order not to hinder the further coil construction, the plate 23 with the hooks 19 and 20 is moved away from the sleeve 18. For this purpose, it makes sense that the housing of the first suction nozzle 5 serves as a guide.

Das Wiederansetzen des Fadens in der Spinnvorrichtung 1 geschieht vorzugsweise während des Verfahrensschrittes 2d. Nach dem Wiederansetzen des Fadens 2 in der Spinnvorrichtung 1 wird wieder Faden 2 produziert, welcher gemäß den Darstellungen der Figuren 2e und 2f auf die Hülse 18 aufgewickelt wird.The re-starting of the thread in the spinning device 1 is preferably carried out during the process step 2d. After restarting the thread 2 in the spinning device 1 again thread 2 is produced, which according to the representations of FIGS. 2e and 2f is wound on the sleeve 18.

In den Figuren 3a bis 3h ist ein gegenüber den Figuren 2a bis 2f abgewandeltes Verfahren dargestellt. Ein wesentlicher Unterschied besteht darin, dass das zum Wiederanlegen des Fadens 2 an eine neue Hülse 18 verwendete Fadenende von einer an dieser Arbeitsstelle fertiggestellten Spule 7 genommen wird.In the FIGS. 3a to 3h is one opposite the FIGS. 2a to 2f modified method shown. An essential difference is that the thread end used to re-apply the thread 2 to a new sleeve 18 is taken from a coil 7 completed at this work site.

Die Führungseinrichtung 22 weist hierfür einen Schneidblock 21 und ein bewegliches Führungselement 25 auf. Schneidblock 21 und Führungselement 25 sind an der Platte 23 angeordnet, welche sich an dem Gehäuse der ersten Saugdüse 5 befindet. Das Führungselement 25 weist eine Schneide 26 und eine Führungsnut 27 auf. Die Schneide 26 ist V-förmig ausgebildet und kann damit den Faden 2 erfassen und Richtung Schneidblock 21 bewegen. Während dieser Bewegung wird Faden 2 zwischen der Spule 7 und der Mündung der erste Saugdüse 5 ausgelenkt und, sobald der Schneidblock 21 erreicht wird, geschnitten. Dies ist in Figur 3b dargestellt.For this purpose, the guide device 22 has a cutting block 21 and a movable guide element 25. Cutting block 21 and guide element 25 are arranged on the plate 23, which is located on the housing of the first suction nozzle 5. The guide element 25 has a cutting edge 26 and a guide groove 27. The cutting edge 26 is V-shaped and can thus detect the thread 2 and move the cutting block 21. During this movement, thread 2 is deflected between the spool 7 and the mouth of the first suction nozzle 5 and, as soon as the cutting block 21 is reached, cut. This is in FIG. 3b shown.

In dieser Figur ist auch angedeutet, dass die Absaugung A1 durch die erste Saugdüse 5 eingeschaltet ist. Dies ist beispielsweise dann erforderlich, wenn der Faden auf der fertiggestellten Spule 7 gesucht, gefunden und von der Spule 7 abgezogen werden soll. In diesem Fall wird das gefundene Fadenende in die Absaugung A1 eingesaugt und anschließend, wie in den Figuren 1b und 1c dargestellt und beschrieben, in den Eingriff der Abzugswalzen 3 gebracht.In this figure, it is also indicated that the suction A1 is turned on by the first suction nozzle 5. This is necessary, for example, when the thread on the finished coil 7 sought, found and deducted from the coil 7. In this case, the thread end found is sucked into the suction A1 and then, as in the Figures 1b and 1c shown and described, brought into engagement of the take-off rolls 3.

In einem anderen Fall kann ein fliegender Spulenwechsel erfolgen, bei dem der Faden 2 weiter produziert wird. Dabei wird der Faden 2 durch die Abzugswalzen 3 in die Absaugung A2 gefördert. Die Absaugung A1 ist in diesem Fall anders als in Figur 3b dargestellt, ausgeschaltet. Der Faden 2 wird entweder fortlaufend in die Absaugung 12 hinein gefördert und dort entsorgt. Alternativ ist es möglich, dass der Faden 2 gestoppt wird und anschließend wieder neu in der Spinnvorrichtung 1 angesetzt werden muss.In another case, a flying bobbin change take place in which the thread 2 is further produced. In this case, the thread 2 is conveyed through the take-off rolls 3 into the suction A2. The suction A1 is different in this case than in FIG. 3b shown, switched off. The thread 2 is either continuously fed into the suction 12 and disposed of there. Alternatively, it is possible that the thread 2 is stopped and then re-set in the spinning device 1 again.

Gemäß Figur 3c wird der Faden 2 durch die Abzugswalzen 3 gehalten oder gefördert. Der Faden 2 befindet sich nunmehr in der zweiten Saugdüse 12, deren Absaugung A2 eingeschaltet ist. Das andere, zur Spule 7 hin verlaufende, abgetrennte Fadenende wird auf die Spule 7 aufgewickelt. Die Spule 7 kann sodann aus der Spulvorrichtung 6 entnommen werden.According to Figure 3c the yarn 2 is held or conveyed by the take-off rolls 3. The thread 2 is now in the second suction nozzle 12, the suction A2 is turned on. The other, the coil 7 towards extending, separated thread end is wound onto the bobbin 7. The coil 7 can then be removed from the winding device 6.

Nachdem die Spule 7 gegen eine leere Hülse 18 gemäß Figur 3d ausgetauscht wurde, bewegt sich das Führungselement 25 in entgegengesetzter Richtung und führt mithilfe der Führungsnut 27 den Faden 2 von dem Schneidblock 21 weg. Der Faden 2 ist nunmehr aufgespannt zwischen der Führungsnut 27 und der Mündung der zweiten Saugdüse 12 und gegenüber dem Spulenteller 9 mit den Zähnen 10.After the coil 7 against an empty sleeve 18 according to 3d figure has been exchanged, the guide member 25 moves in the opposite direction and leads using the guide groove 27, the thread 2 away from the cutting block 21. The thread 2 is now stretched between the Guide groove 27 and the mouth of the second suction nozzle 12 and with respect to the reel plate 9 with the teeth 10th

Ebenso wie bei Figur 2b senkt sich nunmehr gemäß Figur 3e der Spulenhalter 8 mit der Hülse 18 und den beiden Spulentellern 9 und 9' auf die Spulwalze 11 (Figur 1) ab, beginnt zu drehen und die Zähne 10 des Spulentellers 9 greifen in den aufgespannten Faden 2 zwischen dem Führungselement 25 und der zweiten Saugdüse 12 ein. Der Faden 2 wird von den Zähnen 10 erfasst und auf die Hülse 18 gezogen und dort zwischen der Hülse 18 und dem Spulenteller 9 gemäß Figur 3f fixiert. Das überstehende Fadenende, welches noch in die zweite Saugdüse 12 hineinragt, wird mittels der Trenneinrichtung 24 abgeschnitten und über die zweite Absaugung A2 entsorgt.As with FIG. 2b now lowers accordingly FIG. 3e the bobbin holder 8 with the sleeve 18 and the two bobbin plates 9 and 9 'on the winding roller 11 ( FIG. 1 ), begins to rotate and the teeth 10 of the reel disc 9 engage in the tensioned thread 2 between the guide member 25 and the second suction nozzle 12 a. The thread 2 is detected by the teeth 10 and pulled on the sleeve 18 and there between the sleeve 18 and the reel disc 9 according to FIG. 3f fixed. The projecting thread end, which still protrudes into the second suction nozzle 12 is cut off by means of the separator 24 and disposed of via the second suction A2.

Der in der Führungsnut 27 liegende Faden 2 wird nun an den Fadenführer 16 übergeben, welcher vor der Hülse 18 hin und her changiert (Figur 3g). Die Übergabe kann beispielsweise wieder durch eine Bewegung der Platte 23 erfolgen, wodurch der Faden 2 aus der Führungsnut 27 herausrutscht oder aber auch durch die Bewegung des Fadenführers 16, welcher in den Verlauf des Fadens 2 gefahren wird und dort höhere Mitnahmekräfte auf den Faden 2 ausübt als die Führungsnut 27.The yarn 2 lying in the guide groove 27 is now transferred to the yarn guide 16, which oscillates back and forth in front of the sleeve 18 ( FIG. 3g ). The transfer can for example be done by a movement of the plate 23, whereby the thread 2 slips out of the guide groove 27 or by the movement of the thread guide 16, which is driven in the course of the thread 2 and there exerts higher driving forces on the thread 2 as the guide groove 27.

Anschließend wird gemäß Figur 3h die Platte 23 mit dem Führungselement 25 und dem Schneidblock 21 in eine Position verschoben, welche von der Spule 7 weiter entfernt ist, um das Aufwickeln des Fadens 2 nicht zu behindern.Subsequently, according to FIG. 3h the plate 23 is moved with the guide member 25 and the cutting block 21 in a position which is further away from the coil 7, so as not to hinder the winding of the thread 2.

In Figur 4 ist ein alternatives Führungselement 25 dargestellt. Die Führungsnut 27 ist dabei so angeordnet, dass der Faden 2 vor der Hülse 18 hin und her changiert werden kann. Die Führungsnut 27 hat somit zusätzlich die Funktion des Fadenführers 16. Dementsprechend bleibt das Führungselement 25 auch im Bereich unmittelbar vor der Spule 7 und wird nicht entsprechend Figur 3h aus diesem Bereich zurück geschoben. Vorteilhaft bei dieser Ausführung ist es, dass keine Übergabe von dem Führungselement 25 zu dem Fadenführer 16 erfolgen muss.In FIG. 4 an alternative guide element 25 is shown. The guide groove 27 is arranged so that the thread 2 before the sleeve 18 can be alternated back and forth. The guide groove 27 thus has the additional function of the thread guide 16. Accordingly, the guide member 25 also remains in the area immediately in front of the coil 7 and is not corresponding FIG. 3h pushed back from this area. Advantageous in this Embodiment is that no transfer of the guide member 25 must be made to the yarn guide 16.

In Figur 5 ist eine weitere alternative Ausführung der Führungseinrichtung 22 dargestellt. Das Führungselement 25 weist lediglich eine Schneide 26 auf. Es ist drehbar in Bezug auf den Schneidblock 21 gelagert. Sobald der Faden 2 in den Bereich zwischen der Schneide 26 und dem Schneidblock 21 gelangt, wird die Schneide 26 in Richtung auf den Schneidblock 21 gedreht und durchtrennt den Faden 2. Diese Ausführung kann wegen des geringeren Platzbedarfs vorteilhaft sein.In FIG. 5 a further alternative embodiment of the guide device 22 is shown. The guide element 25 has only one cutting edge 26. It is rotatably supported with respect to the cutting block 21. As soon as the thread 2 reaches the area between the cutting edge 26 and the cutting block 21, the cutting edge 26 is rotated in the direction of the cutting block 21 and cuts through the thread 2. This embodiment can be advantageous because of the smaller space requirement.

Die vorliegende Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt. Insbesondere ist zu beachten, dass die dargestellten Bauteile lediglich skizziert sind und bei einer konkreten Ausgestaltung anders aussehen können. Insbesondere können der Spulenteller 9 und dessen Zähne 10 anders gestaltet sein. So kann beispielsweise eine Klemmung des Fadens 2 durch eine parallel zum Spulenteller 9 verlaufende, enge Nut erfolgen, in welcher sich der Faden 2 verfängt. In diesem Fall ist das Aufspannen des Fadens 2 derart durchzuführen, dass der Faden 2 in dieser Nut zu liegen kommt, wenn der Spulenhalter 8 die Hülse 18 in den gespannten Faden 2 absenkt. Weitere Abwandlungen im Rahmen der Patentansprüche sind ebenso möglich wie eine Kombination der Merkmale, auch wenn diese in unterschiedlichen Ausführungsbeispielen dargestellt und beschrieben sind.The present invention is not limited to the illustrated and described embodiments. In particular, it should be noted that the components shown are merely outlined and may look different in a specific embodiment. In particular, the coil plate 9 and its teeth 10 can be designed differently. Thus, for example, a clamping of the thread 2 by a parallel to the reel disc 9 extending, narrow groove, in which the thread 2 catches. In this case, the tensioning of the thread 2 is to be carried out in such a way that the thread 2 comes to lie in this groove when the bobbin holder 8 lowers the sleeve 18 into the tensioned thread 2. Further modifications within the scope of the claims are possible as well as a combination of features, even if they are shown and described in different embodiments.
