  • a reserve winding is understood to be a winding of the thread on the sleeve, which bridges the distance between a fixing winding arranged outside the coil width and the coil and in which the thread is wound in a thread-like manner onto the sleeve. When the fixing winding is positioned within the coil width, there is no reserve winding.
  • the device is a continuous winder with at least two each driven winding spindles on the sleeves of the thread is wound alternately.
  • the thread is severed so that the end of the preceding thread thus formed is still wound on the circumference of the full bobbin, while the thus formed new beginning of the thread is detected by a capture area of the empty shell and anchored there, and then the winding takes place on this new sleeve.
  • the severing of the thread can be done in any manner, for example by tearing due to increased thread tension or with a cutting device.
  • the invention is also independent of the manner of forming the capture area.
  • the capture area can be realized on the respective sleeve, z. B. within the coil width, but often outside the coil width.
  • the catching area can be made, for example, as one or more incisions arranged distributed over the circumference of the sleeve, or else by arranging a hooked strip strip or the like.
  • the catching area can also be realized on a catching device, which is part of the winding spindle and thus independent of the sleeve.
  • a method and a winding machine of the type described is known from DE 197 43 278 C2 known.

  • the traversing device, the contact roller, the winding spindle and the two yarn guides are provided on one side of the thread in such mutual relative position that the thread is guided by the swiveling arm carrying the yarn guide into the gap both from the surface of the empty sleeve as well as released from the traversing device, while the thread is applied during the return pivoting of the pivot arm using the head thread guide and the first thread guide to the capture area of the empty shell enlarging the wrap angle.
  • the two yarn guides and the associated drives a considerable machine effort is required.
  • a movably controlled thread holder is used to secure the thread in the charging yarn guide and only specifically let emerge from this.
  • the yarn is deflected twice in approximately right angles, which can lead to damage to the thread, especially if it is sensitive Spulgut.
  • the position and the wound thread length of the fixing winding and the reserve winding are fixed and are therefore not variable. They depend on the geometry of the sleeves used, in particular on the arrangement of the catching area on the sleeve.

  • This device also has, in addition to the traversing yarn guide a traversable in traversing yarn guide, which allows the acquisition of the yarn in a certain range of the traverse stroke to form a winding outside the traverse stroke.
  • the winding can be formed at the beginning or at the end of the winding cycle.
  • the first thread guide is also provided here in the region of the traversing device and serves to lift the thread out of the traversing device and to position it relative to the trapping region of the empty tube.
  • the second and the third yarn guide are even provided in duplicate and mounted on a turntable, respectively in the sectors between the two winding spindles.
  • the second thread guide also serves here to apply the end of the running thread on the full bobbin, while the third thread guide cooperates with the first thread guide, in such a way that the thread between these two thread guides perpendicular to the winding spindle direction and thus relative to the capture area of empty sleeve is positioned.
  • the catching area is formed by an incision provided perpendicular to the winding spindle direction on the circumference of the empty shell. The formation of the catch area in another way is not possible. The disadvantages described above occur here increasingly.
  • the US 4,298,171 shows a winder with a turntable and two winding spindles arranged thereon.
  • the winding spindles are used to hold the sleeves and are in Spulspindelutter, ie in the direction of the axes of the winding spindles, movable to temporarily couple the respective winding spindle with the sleeve sitting thereon with a drive which accelerates the winding spindle to the speed of the contact roller, which then takes over the further drive of the winding spindle on the winding cycle.
  • the DE 26 43 421 shows a method and apparatus for winding a continuous filament on a sleeve into a spool. It is used within the traversing a Kehrgewindewelle whose spatial position is axially changed by means of a cylinder by a fixed stroke in Spulspindelraum.
  • the Kehrgewindewelle is driven by a controllable in its speed and reversible in its direction of rotation motor.
  • the Kehrgewindewelle has in addition to the normal laying a stepless groove portion into which the traversing thread guide enters by reversing the direction of rotation of the Kehrgewindewelle.
  • a switch in the pitchless groove portion allows the traversing yarn guide in conjunction with a new direction of rotation reversal to reach the laying groove for the purpose of building the coil on the sleeve. It sleeves are used, which have a catching area.
  • the speed of the Kehrgewindewelle is initially reduced to one for the formation of a fixing winding - there called thread reserve - favorable value and the thread wound at this reduced speed on the full spool on.
  • thread reserve - favorable value the thread wound at this reduced speed on the full spool on.
  • a start-of-take detector is actuated in order to bring the reverse-thread shaft into its starting position.
  • a timer for switching a control device to a forward rotation state is turned on.
  • the disadvantage here is that the method of the traversing thread guide in the stepless groove section a reversal of direction must be done. The drive of the Kehrgewindewelle must therefore be a reversible motor.
  • Another disadvantage is that only sleeves can be used with catching range and with fixed geometric dimensions. A flexible adaptation to sleeves with different dimensions is not possible.
  • the formation of the layers of the fixing winding and the reserve winding are constant. The formation of the thread lengths of the fixing winding and the reserve winding are randomly dependent on the time at which the traversing yarn guide leaves the pitchless groove portion.
  • the pitchless groove portion of this winder can be arranged only outside the laying width of the endless Kehrgewindenut. This means that the fixing winding of the thread can only be arranged at one end region of the sleeve outside the laying width or very large axial displacement paths are required for the traversing device, if the fixing winding, e.g. should be arranged in the middle of the laying width.
  • the invention has for its object to provide a method and a winder and the type described in which position and thread length of the fixing winding or a fixing winding with subsequent reserve winding are variably preselected, namely when using sleeves with and without catching range.
  • the method of the type described above is characterized according to the invention characterized in that the once detected spatial position of the driven traversing yarn guide of the traversing device is stored and used as a reference position in the formation of the fixing winding and the spool, and that from the reference position spatial positions at which the traversing yarn guide the traversing device is just about the winding cycle, determined and tuned to the winding speed.
  • the traversing device is traversed in the winding spindle direction with the traversing yarn guide, thereby controlling the axial movement of the traversing device in relation to the spatial positions of the traversing yarn guide of the traversing device over the winding cycle such that on the sleeve successively the fixing winding, the reserve winding and the coil are determined and formed according to position and thread length.
  • the method requires first of all to know at an arbitrary point in time where the traversing yarn guide of the traversing device is located. This arbitrary time can be selected anew for each winding cycle. But it is also possible to select the arbitrary time after switching on the main switch of the winder under application of the control voltage once and assign a sequence of Spulticianen or Spulreisen. At this arbitrary time, the spatial position of the driven traversing thread guide of the traversing device is detected once. This signal is determined by location and time, is stored and used as a reference position in the formation of the fixing winding, if necessary. Also the reserve winding, and the coil, so over the entire winding cycle.
  • the spatial positions of the traversing yarn guide are determined in their time course over the winding cycle, so that it is known at any time, where is currently the traversing yarn guide. From the knowledge of these spatial positions out, it is then possible, especially at reduced speed of the Kehrgewindewelle targeted to approach individual selected positions in order to take in relation to the drive of the winding spindle or the peripheral speed of the straight wound thread on the sleeve, the various measures , For example, a fixing winding, if necessary. A subsequent reserve winding, and to form a coil, in which each of the local position and the thread length are set repeatable.
  • the fixing winding with subsequent reserve winding is arranged in all cases outside the laying width of the bobbin, it is necessary to move the traversing device in the winding spindle direction to control these positions.
  • This axial movement of the traversing device is controlled in relation to the known spatial positions of the traversing yarn guide over time so that relative to the sleeve on the winding spindle successively the fixing winding, the reserve winding and the spool, each adjustable and repeatable determined by position and thread length are formed.
  • the new method has a number of advantages.
  • the fixing winding, if necessary with subsequent reserve winding, and the bobbin can be reproduced reproducibly according to layers and thread lengths according to the wishes of the user precisely defined and adhered to. It may be important to hold by the bobbin exchange impaired Spulgut with certainty in the fixing winding to form the reserve winding z: B. from unchanged Spulgut, as well as the coil.
  • the arrangement and the corresponding mechanical effort for the drive of a second and third yarn guide from the prior art, which come into contact with the yarn during the bobbin change, is superfluous. Due to the extent reduced number of parts for the thread transfer also results in fewer points of friction for the Spulgut. The Spulgut is deflected gentler.
  • the speed of the Kehrgewindewelle can be regulated or braked to at least approximately zero, that the traversing yarn assumes the selected relative position to the laying width of the winding spindle.
  • This can be used with laying groove trained in the usual way Kehrgewindewellen.
  • the additional arrangement of an unpolluted groove portion and a switch is basically unnecessary.
  • the traversing yarn guide is exactly at the selected location within the laying width, and it is only dependent on the time, with which thread length the fixing winding is applied location accurate.
  • the laying channel in the counter-rotating shaft has deflections which have a comparatively small pitch, these areas can also be used without accurate attainment of the rotational speed 0, at least for fixing windings of short thread length. If the fixing winding is not to be mounted within the laying width or in one of the two end regions of the bobbin, but outside the laying width or the bobbin width, which is predominantly the case, the axial displacement of the traversing device in the winding spindle direction is required. This shift is made variably adjustable or controllable, so that the exact position of the fixing winding relative to the coil on the sleeve selectable and thus different for winding different coils can be fixed. It also eliminates the need to use a reversible motor for driving the Kehrgewindewelle.
  • Any spatial position of the driven traversing yarn guide of the traversing device can be detected with a first sensor, stored and used as a reference position in the formation of the fixing winding, if necessary.
  • the reserve winding, and the coil This determines the beginning of a control process and thus the winding travel.
  • a first sensor can be activated at any time. The sensor monitors and detects the path of the driven traversing yarn guide. He sets simultaneously with the determination of a spatial position of the traversing yarn guide the beginning of a time and thus forms a reference position in order to relate to it during the winding cycle again and again to make a statement where the traversing yarn guide is currently located during the winding cycle.
  • each bobbin change it is also possible after each bobbin change to approach a starting position in which the spatial position of the traversing yarn guide is known or fixed and which then represents the beginning of a winding cycle.
  • a start position can be detected or approached with an absolute encoder or an incremental encoder.
  • the rotational speed of the counter-twisting shaft can advantageously be detected continuously in time with a second sensor.
  • precision winding it is known to change the winding ratio over the winding cycle and thus the speed of the counter-twisting shaft.
  • By detecting the change in the counterbore shaft can be accurately determined, in relation to the reference position, at which point at which time the traversing thread guide is relative to the winding spindle. You can also do without the second sensor. It is then possible to repeatedly use the first sensor and to close its signals with known geometry of the laying channel on the spatial position of the traversing yarn guide over a double stroke. This becomes particularly simple if the speed of the counter-clockwise shaft between two signals is kept constant.
  • subsequent reserve winding, and the coil in particular according to the method of claim 1 or 2, is initially customary per se. It is characterized according to the invention in that the signal of the first sensor or a corresponding element of the once detected spatial position of the driven traversing yarn guide the traversing device supplied to the control device, stored there in temporal association and as a reference position in the formation of the fixing winding, if necessary.

Description

Die Erfindung betrifft ein Verfahren und eine Spulmaschine zum Aufwickeln eines kontinuierlich zulaufenden Fadens auf einer Hülse zu einer Spule, mit den in den Oberbegriffen der unabhängigen Patentansprüche angegebenen Merkmalen. Bei dem Verfahren zum Aufwickeln eines kontinuierlich zulaufenden Fadens zu einer Spule geht es darum, den Faden auf je einer Hülse unter Bildung einer Fixierwicklung, ggfs. einer Reservewicklung, und letztlich der Spule möglichst schonend aufzuwickeln.The invention relates to a method and a winding machine for winding a continuously tapered thread on a sleeve to form a coil, having the features specified in the preambles of the independent claims. In the method for winding a continuously tapered thread to form a bobbin, it is important to wind the thread on each sleeve to form a fixing winding, if necessary. A reserve winding, and ultimately the coil as gently as possible.

Unter einer Fixierwicklung wird eine wulstartige Wicklung des Fadens auf der Hülse verstanden, bei der die Fadenlagen in einem eng begrenzten axialen Bereich der Hülse, und zwar entweder mit Abstand zu der Spule, also außerhalb der Verlegebreite, oder im Bereich der Spulen- oder Verlegebreite übereinander gewickelt werden, um den Anfang des Fadens auf der Hülse zu fixieren. Unter einer Reservewicklung wird eine Wicklung des Fadens auf der Hülse verstanden, die den Abstand zwischen einer außerhalb der Spulenbreite angeordneten Fixierwicklung und der Spule überbrückt und in der der Faden gewindeartig auf der Hülse aufgewickelt wird. Wenn die Fixierwicklung innerhalb der Spulenbreite positioniert ist, gibt es keine Reservewicklung.A fixing winding is understood to mean a bead-like winding of the thread on the sleeve, in which the thread layers overlap one another in a narrow axial region of the sleeve, either at a distance from the coil, ie outside the laying width, or in the region of the coil or laying width be wound to fix the beginning of the thread on the sleeve. A reserve winding is understood to be a winding of the thread on the sleeve, which bridges the distance between a fixing winding arranged outside the coil width and the coil and in which the thread is wound in a thread-like manner onto the sleeve. When the fixing winding is positioned within the coil width, there is no reserve winding.

Hinsichtlich der Vorrichtung geht es um eine kontinuierlich arbeitende Spulmaschine mit mindestens zwei jeweils angetriebenen Spulspindeln, auf deren Hülsen der Faden abwechselnd aufgewickelt wird. In der Wechselposition wird der Faden durchtrennt, so dass das so gebildete Ende des vorauslaufenden Fadens noch auf den Umfang der vollen Spule aufgewickelt wird, während der so gebildete neue Beginn des Fadens von einem Fangbereich der leeren Hülse erfasst und dort verankert wird und anschließend der Aufwickelvorgang auf dieser neuen Hülse stattfindet. Das Durchtrennen des Fadens kann auf beliebige Art und Weise geschehen, beispielsweise durch Durchreißen infolge erhöhter Fadenspannung oder mit einer Schneideinrichtung. Die Erfindung ist auch unabhängig von der Art und Weise der Ausbildung des Fangbereiches. Der Fangbereich kann an der jeweiligen Hülse verwirklicht sein, z. B. innerhalb der Spulenbreite, häufig aber außerhalb der Spulenbreite. Der Fangbereich kann beispielsweise als ein oder mehrere über den Umfang der Hülse verteilt angeordneten Einschnitte oder aber auch durch Anordnung eines Hakenbandstreifens o. dgl. erfolgen. Der Fangbereich kann aber auch an einer Fangeinrichtung verwirklicht sein, die Bestandteil der Spulspindel und damit von der Hülse unabhängig ist.With regard to the device is a continuous winder with at least two each driven winding spindles on the sleeves of the thread is wound alternately. In the change position, the thread is severed so that the end of the preceding thread thus formed is still wound on the circumference of the full bobbin, while the thus formed new beginning of the thread is detected by a capture area of the empty shell and anchored there, and then the winding takes place on this new sleeve. The severing of the thread can be done in any manner, for example by tearing due to increased thread tension or with a cutting device. The invention is also independent of the manner of forming the capture area. The capture area can be realized on the respective sleeve, z. B. within the coil width, but often outside the coil width. The catching area can be made, for example, as one or more incisions arranged distributed over the circumference of the sleeve, or else by arranging a hooked strip strip or the like. The catching area can also be realized on a catching device, which is part of the winding spindle and thus independent of the sleeve.

Ein Verfahren und eine Spulmaschine der beschriebenen Art ist aus der DE 197 43 278 C2 bekannt. Der kontinuierlich zulaufende Faden wird auf einer Hülse zu einer Spule aufgewickelt, indem die Hülse auf einer antreibbaren Spulspindel festgesetzt wird und der Faden über einen ortsfesten Kopffadenführer, eine Changiereinrichtung mit einem insbesondere hin- und hergehend angetriebenen Changierfadenführer und eine Kontaktwalze auf der Hülse und der Spule unter Bildung einer Fixierwicklung, einer Reservewicklung und der Spule verlegt wird. Es kommen Hülsen zum Einsatz, die mit einem Fangbereich ausgestattet sind. Außer dem Chargierfadenführer sind zwei weitere Fadenführer vorgesehen, die auf einem Schwenkarm gelagert sind, der in den Spalt zwischen der Spule und einer leeren Hülse einschwenkbar gelagert ist. Der erste Fadenführer ist in Spulspindelrichtung bewegbar und dient dazu, den Faden relativ zu dem Fangbereich der leeren Hülse zu positionieren. Der zweite Fadenführer leitet das auf die volle Spule auflaufende Ende des Fadens. Die Changiereinrichtung, die Kontaktwalze, die Spulspindel und die beiden Fadenführer sind auf einer Seite des Fadens in einer solchen gegenseitigen Relativlage vorgesehen sind, dass der Faden nach dem Einschwenken des die Fadenführer tragenden Schwenkarms in den Spalt sowohl von der Oberfläche der leeren Hülse frei geführt ist als auch von der Changiereinrichtung freikommt, während der Faden während des Rückschwenkens des Schwenkarms unter Nutzung des Kopffadenführers und des ersten Fadenführers an den Fangbereich der leeren Hülse unter Vergrößerung des Umschlingungswinkels angelegt wird. Zur Realisierung des Schwenkarms, der beiden Fadenführer und der zugehörigen Antriebe ist ein erheblicher maschineller Aufwand erforderlich. Außerdem wird ein bewegbar gesteuerter Fadenhalter eingesetzt, um den Faden in dem Chargierfadenführer zu sichern und erst gezielt aus diesem austreten zu lassen. Beim maschinellen Spulenwechsel wird der Faden in angenähert rechten Winkeln zweimal umgelenkt, was zu Beschädigungen des Fadens führen kann, insbesondere, wenn es sich um empfindliches Spulgut handelt. Die Lage und die aufgewickelte Fadenlänge der Fixierwicklung und der Reservewicklung liegen fest und sind damit nicht variabel. Sie sind von der Geometrie der eingesetzten Hülsen, insbesondere von der Anordnung des Fangbereiches auf der Hülse abhängig.A method and a winding machine of the type described is known from DE 197 43 278 C2 known. The continuously tapered thread is wound on a sleeve into a coil by the sleeve is fixed on a driven winding spindle and the thread via a stationary head thread guide, a traversing device with a particular reciprocally driven traversing yarn guide and a contact roller on the sleeve and the spool is laid to form a fixing winding, a reserve winding and the coil. Sleeves are used, which are equipped with a catch area. In addition to the Chargierfadenführer two more yarn guide are provided which are mounted on a pivot arm which is mounted in the gap between the coil and an empty sleeve swivel. The first thread guide is movable in the winding spindle direction and serves to position the thread relative to the catching area of the empty tube. The second yarn guide directs the end of the yarn running onto the full bobbin. The traversing device, the contact roller, the winding spindle and the two yarn guides are provided on one side of the thread in such mutual relative position that the thread is guided by the swiveling arm carrying the yarn guide into the gap both from the surface of the empty sleeve as well as released from the traversing device, while the thread is applied during the return pivoting of the pivot arm using the head thread guide and the first thread guide to the capture area of the empty shell enlarging the wrap angle. For the realization of the swing arm, the two yarn guides and the associated drives a considerable machine effort is required. In addition, a movably controlled thread holder is used to secure the thread in the charging yarn guide and only specifically let emerge from this. When machine bobbin change the yarn is deflected twice in approximately right angles, which can lead to damage to the thread, especially if it is sensitive Spulgut. The position and the wound thread length of the fixing winding and the reserve winding are fixed and are therefore not variable. They depend on the geometry of the sleeves used, in particular on the arrangement of the catching area on the sleeve.

Aus der DE-A-42 41 290 ist eine Vorrichtung zum Aufwickeln eines Fadens auf einer Hülse zu einer Spule bekannt, bei der der Faden während der Spulreise mit einem Changierfadenführer über die Länge des Changierhubes hin- und hergeführt wird. Auch diese Vorrichtung weist zusätzlich zu dem Changierfadenführer einen in Changierrichtung verfahrbaren Fadenführer auf, der die Übernahme des Fadens in einem bestimmten Bereich des Changierhubes gestattet, um eine Wicklung außerhalb des Changierhubes zu bilden. Die Wicklung kann zu Beginn oder auch am Ende der Spulreise gebildet werden. Entlang der Bewegungsbahn des Changierfadenführers gelegene Lichtschranken werden für eine gewisse Zeit innerhalb der Spulreise aktiviert, um einmal die Bewegungsrichtung und zum anderen die Stellung des Changierfadenführers zu ermitteln und durch Abgabe entsprechender Signale den Fadenführer über seinen Antrieb so zu betätigen, dass er den Faden freigibt.From the DE-A-42 41 290 a device for winding a thread on a sleeve to a bobbin is known, in which the thread during the winding cycle with a traversing yarn guide over the length of the traverse stroke back and forth. This device also has, in addition to the traversing yarn guide a traversable in traversing yarn guide, which allows the acquisition of the yarn in a certain range of the traverse stroke to form a winding outside the traverse stroke. The winding can be formed at the beginning or at the end of the winding cycle. Along the trajectory of the traversing yarn guide located light barriers are activated for a certain time within the winding cycle to determine the direction of movement and on the other hand, the position of the traversing yarn guide and to operate the yarn guide via its drive by issuing appropriate signals so that it releases the thread.

Weiter gibt es Spulmaschinen, die mit sogar drei Fadenführern arbeiten, wodurch sich grundsätzlich der Aufwand für die Ausbildung und den Antrieb dieser drei Fadenführer erhöht. Eine solche Spulmaschine ist beispielsweise aus der DE 29 07 848 C2 bekannt. Der erste Fadenführer ist auch hier im Bereich der Changiereinrichtung vorgesehen und dient dazu, den Faden aus der Changiereinrichtung auszuheben und relativ zum Fangbereich der Leerhülse zu positionieren. Der zweite und der dritte Fadenführer sind sogar in doppelter Ausfertigung vorgesehen und auf einem Drehteller, jeweils in den Sektoren zwischen den beiden Spulspindeln gelagert. Der zweite Fadenführer dient auch hier dazu, das Ende des ablaufenden Fadens auf der vollen Spule anzulegen, während der dritte Fadenführer mit dem ersten Fadenführer zusammenarbeitet, und zwar derart, dass der Faden zwischen diesen beiden Fadenführern senkrecht zur Spulspindelrichtung und damit relativ zu dem Fangbereich der leeren Hülse positioniert wird. Der Fangbereich ist durch einen senkrecht zur Spulspindelrichtung vorgesehenen Einschnitt auf dem Umfang der leeren Hülse gebildet. Die Ausbildung des Fangbereiches in anderer Art und Weise ist nicht möglich. Die oben beschriebenen Nachteile treten hier vermehrt auf.Next there are winding machines that even with three thread guides work, which basically increases the cost of training and the drive of these three thread guides. Such a winder is for example from the DE 29 07 848 C2 known. The first thread guide is also provided here in the region of the traversing device and serves to lift the thread out of the traversing device and to position it relative to the trapping region of the empty tube. The second and the third yarn guide are even provided in duplicate and mounted on a turntable, respectively in the sectors between the two winding spindles. The second thread guide also serves here to apply the end of the running thread on the full bobbin, while the third thread guide cooperates with the first thread guide, in such a way that the thread between these two thread guides perpendicular to the winding spindle direction and thus relative to the capture area of empty sleeve is positioned. The catching area is formed by an incision provided perpendicular to the winding spindle direction on the circumference of the empty shell. The formation of the catch area in another way is not possible. The disadvantages described above occur here increasingly.

Die US 4,298,171 zeigt eine Spulmaschine mit einem Drehteller und zwei darauf angeordneten Spulspindeln. Die Spulspindeln dienen zur Aufnahme der Hülsen und sind in Spulspindelrichtung, also in Richtung der Achsen der Spulspindeln, bewegbar, um die jeweilige Spulspindel mit der darauf sitzenden Hülse temporär mit einem Antrieb zu koppeln, der die Spulspindel auf die Drehzahl der Kontaktwalze beschleunigt, die dann den weiteren Antrieb der Spulspindel über die Spulreise übernimmt.The US 4,298,171 shows a winder with a turntable and two winding spindles arranged thereon. The winding spindles are used to hold the sleeves and are in Spulspindelrichtung, ie in the direction of the axes of the winding spindles, movable to temporarily couple the respective winding spindle with the sleeve sitting thereon with a drive which accelerates the winding spindle to the speed of the contact roller, which then takes over the further drive of the winding spindle on the winding cycle.

Die DE 26 43 421 zeigt ein Verfahren und eine Vorrichtung zum Aufwickeln eines kontinuierlich zulaufenden Fadens auf einer Hülse zu einer Spule. Es wird innerhalb der Changiereinrichtung eine Kehrgewindewelle eingesetzt, deren räumliche Lage axial mittels eines Zylinders um einen festgelegten Hub in Spulspindelrichtung veränderbar ist. Die Kehrgewindewelle wird mit einem in seiner Drehzahl steuerbaren und in seiner Drehrichtung umkehrbaren Motor angetrieben. Die Kehrgewindewelle besitzt neben der normalen Verlegenut einen steigungslosen Nutabschnitt, in die der Changierfadenführer durch Drehrichtungsumkehr der Kehrgewindewelle einläuft. Eine Weiche in dem steigungslosen Nutabschnitt ermöglich es dem Changierfadenführer in Verbindung mit einer erneuten Drehrichtungsumkehr, die Verlegenut zwecks Aufbau der Spule auf der Hülse zu erreichen. Es werden Hülsen eingesetzt, die einen Fangbereich aufweisen. Bei einem automatischen Spulenwechsel wird zunächst die Drehzahl der Kehrgewindewelle auf einen für die Bildung einer Fixierwicklung - dort Fadenreserve genannt - günstigen Wert verringert und der Faden mit dieser verringerten Geschwindigkeit auf der Vollspule weiter aufgewickelt. Durch die nachfolgend eingeleitete Drehrichtungsumkehr wird der Changierfadenführer in den steigungslosen Nutabschnitt überführt. Anschließend erfolgt eine axiale Verschiebung der Kehrgewindewelle um den durch den Zylinder festgelegten Hub, so dass der Faden in den Fangbereich der Leerhülse geiangt. Nach dem Fangen des Fadens im Fangbereich der Leerhülse wird ein Spulbeginn-Detektor betätigt, um die Kehrgewindewelle in ihre Ausgangsstellung zu bringen. Es wird ein Zeitgeber zum Umschalten einer Regelvorrichtung in einen Vorwärtsdrehzustand eingeschaltet. Nachteilig ist dabei, dass zum Verfahren des Changierfadenführers in den steigungslosen Nutabschnitt eine Drehrichtungsumkehr erfolgen muss. Der Antrieb der Kehrgewindewelle muss also ein reversierbarer Motor sein. Weiterhin ist nachteilig, dass nur Hülsen mit Fangbereich und mit festliegenden geometrischen Abmessungen eingesetzt werden können. Eine flexible Anpassung an Hülsen mit unterschiedlichen Abmessungen ist nicht möglich. Die Ausbildung der Lagen der Fixierwicklung und der Reservewicklung sind konstant. Die Ausbildung der Fadenlängen der Fixierwicklung und der Reservewicklung sind zufallsabhängig von dem Zeitpunkt, zu dem der Changierfadenführer den steigungslosen Nutabschnitt verlässt.The DE 26 43 421 shows a method and apparatus for winding a continuous filament on a sleeve into a spool. It is used within the traversing a Kehrgewindewelle whose spatial position is axially changed by means of a cylinder by a fixed stroke in Spulspindelrichtung. The Kehrgewindewelle is driven by a controllable in its speed and reversible in its direction of rotation motor. The Kehrgewindewelle has in addition to the normal laying a stepless groove portion into which the traversing thread guide enters by reversing the direction of rotation of the Kehrgewindewelle. A switch in the pitchless groove portion allows the traversing yarn guide in conjunction with a new direction of rotation reversal to reach the laying groove for the purpose of building the coil on the sleeve. It sleeves are used, which have a catching area. In an automatic bobbin change, the speed of the Kehrgewindewelle is initially reduced to one for the formation of a fixing winding - there called thread reserve - favorable value and the thread wound at this reduced speed on the full spool on. Through the following reversal of direction of rotation of the traversing yarn guide is transferred to the stepless groove section. Subsequently, an axial displacement of the Kehrgewindewelle to the fixed by the cylinder stroke, so that the thread geiangt in the capture range of the empty tube. After catching the thread in the catching area of the empty tube, a start-of-take detector is actuated in order to bring the reverse-thread shaft into its starting position. A timer for switching a control device to a forward rotation state is turned on. The disadvantage here is that the method of the traversing thread guide in the stepless groove section a reversal of direction must be done. The drive of the Kehrgewindewelle must therefore be a reversible motor. Another disadvantage is that only sleeves can be used with catching range and with fixed geometric dimensions. A flexible adaptation to sleeves with different dimensions is not possible. The formation of the layers of the fixing winding and the reserve winding are constant. The formation of the thread lengths of the fixing winding and the reserve winding are randomly dependent on the time at which the traversing yarn guide leaves the pitchless groove portion.

Der steigungslose Nutabschnitt dieser Spulmaschine kann nur außerhalb der Verlegebreite der endlosen Kehrgewindenut angeordnet sein. Das bedeutet, dass die Fixierwicklung des Fadens nur an jeweils einem Endbereich der Hülse außerhalb der Verlegebreite angeordnet werden kann oder aber sehr große axiale Verschiebewege für die Changiereinrichtung nötig sind, wenn die Fixierwicklung z.B. in der Mitte der Verlegebreite angeordnet werden soll.The pitchless groove portion of this winder can be arranged only outside the laying width of the endless Kehrgewindenut. This means that the fixing winding of the thread can only be arranged at one end region of the sleeve outside the laying width or very large axial displacement paths are required for the traversing device, if the fixing winding, e.g. should be arranged in the middle of the laying width.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Spulmaschine und der beschriebenen Art bereitzustellen, bei denen Lage und Fadenlänge der Fixierwicklung oder einer Fixierwicklung mit anschließender Reservewicklung variabel vorwählbar sind, und zwar bei Verwendung von Hülsen mit und ohne Fangbereich.The invention has for its object to provide a method and a winder and the type described in which position and thread length of the fixing winding or a fixing winding with subsequent reserve winding are variably preselected, namely when using sleeves with and without catching range.

Das Verfahren der eingangs beschriebenen Art kennzeichnet sich erfindungsgemäß dadurch, dass die einmalig erfasste räumliche Position des angetriebenen Changierfadenführers der Changiereinrichtung gespeichert und als Referenzposition bei der Bildung der Fixierwicklung und der Spule genutzt wird, und dass aus der Referenzposition räumliche Positionen, an denen sich der Changierfadenführer der Changiereinrichtung über die Spulreise gerade befindet, festgestellt und auf die Spulgeschwindigkeit abgestimmt werden.The method of the type described above is characterized according to the invention characterized in that the once detected spatial position of the driven traversing yarn guide of the traversing device is stored and used as a reference position in the formation of the fixing winding and the spool, and that from the reference position spatial positions at which the traversing yarn guide the traversing device is just about the winding cycle, determined and tuned to the winding speed.

Zur Bildung einer Fixierwicklung, insbesondere mit anschließender Reservewicklung außerhalb der Spulenbreite, wird die Changiereinrichtung mit dem Changierfadenführer in Spulspindelrichtung verfahren, und dabei die axiale Bewegung der Changiereinrichtung in Relation zu den räumlichen Positionen des Changierfadenführers der Changiereinrichtung über die Spulreise so gesteuert, dass auf der Hülse nacheinander die Fixierwicklung, die Reservewicklung und die Spule nach Lage und Fadenlänge festgelegt und gebildet werden.To form a fixing winding, in particular with subsequent reserve winding outside the package width, the traversing device is traversed in the winding spindle direction with the traversing yarn guide, thereby controlling the axial movement of the traversing device in relation to the spatial positions of the traversing yarn guide of the traversing device over the winding cycle such that on the sleeve successively the fixing winding, the reserve winding and the coil are determined and formed according to position and thread length.

Das Verfahren erfordert es, zunächst zu einem beliebig wählbaren Zeitpunkt zu wissen, wo sich der Changierfadenführer der Changiereinrichtung befindet. Dieser beliebig wählbare Zeitpunkt kann bei jeder Spulreise neu gewählt werden. Es ist aber auch möglich, den beliebig wählbaren Zeitpunkt nach dem Einschalten des Hauptschalters der Spulmaschine unter Anlegung der Steuerspannung einmalig zu wählen und einer Folge von Spulbildungen bzw. Spulreisen zuzuordnen. Zu diesem beliebig wählbaren Zeitpunkt wird einmalig die räumliche Position des angetriebenen Changierfadenführers der Changiereinrichtung erfasst. Dieses Signal ist nach Ort und Zeit festgelegt, wird gespeichert und als Referenzposition bei der Bildung der Fixierwicklung, ggfs. auch der Reservewicklung, und der Spule, also über die gesamte Spulreise, genutzt. Aus diesem Signal der Referenzposition werden die räumlichen Positionen des Changierfadenführers in ihrem zeitlichen Verlauf über die Spulreise ermittelt, so dass zu jedem Zeitpunkt bekannt ist, wo sich gerade der Changierfadenführer befindet. Aus der Kenntnis dieser räumlichen Positionen heraus ist es dann möglich, insbesondere bei verminderter Drehzahl der Kehrgewindewelle, gezielt einzelne ausgewählte Positionen anzufahren, um dabei in Relation zu dem Antrieb der Spulspindel bzw. der Umfangsgeschwindigkeit des gerade aufgewickelten Fadens auf der Hülse die verschiedenen Maßnahmen zu ergreifen, beispielsweise eine Fixierwicklung, ggfs. eine anschließende Reservewicklung, und eine Spule zu bilden, bei denen jeweils die örtliche Lage und die Fadenlänge wiederholbar festgelegt sind.The method requires first of all to know at an arbitrary point in time where the traversing yarn guide of the traversing device is located. This arbitrary time can be selected anew for each winding cycle. But it is also possible to select the arbitrary time after switching on the main switch of the winder under application of the control voltage once and assign a sequence of Spulbildungen or Spulreisen. At this arbitrary time, the spatial position of the driven traversing thread guide of the traversing device is detected once. This signal is determined by location and time, is stored and used as a reference position in the formation of the fixing winding, if necessary. Also the reserve winding, and the coil, so over the entire winding cycle. From this signal of the reference position, the spatial positions of the traversing yarn guide are determined in their time course over the winding cycle, so that it is known at any time, where is currently the traversing yarn guide. From the knowledge of these spatial positions out, it is then possible, especially at reduced speed of the Kehrgewindewelle targeted to approach individual selected positions in order to take in relation to the drive of the winding spindle or the peripheral speed of the straight wound thread on the sleeve, the various measures , For example, a fixing winding, if necessary. A subsequent reserve winding, and to form a coil, in which each of the local position and the thread length are set repeatable.

Da die Fixierwicklung mit anschließender Reservewicklung in allen Fällen außerhalb der Verlegebreite der Spule angeordnet wird, ist es erforderlich, die Changiereinrichtung in Spulspindelrichtung zu verfahren, um diese Positionen anzusteuern. Diese axiale Bewegung der Changiereinrichtung wird in Relation zu den bekannten räumlichen Positionen des Changierfadenführers über der Zeit so gesteuert, dass relativ zur Hülse auf der Spulspindel nacheinander die Fixierwicklung, die Reservewicklung und die Spule, jeweils einstellbar und wiederholbar festgelegt nach Lage und Fadenlänge gebildet werden.Since the fixing winding with subsequent reserve winding is arranged in all cases outside the laying width of the bobbin, it is necessary to move the traversing device in the winding spindle direction to control these positions. This axial movement of the traversing device is controlled in relation to the known spatial positions of the traversing yarn guide over time so that relative to the sleeve on the winding spindle successively the fixing winding, the reserve winding and the spool, each adjustable and repeatable determined by position and thread length are formed.

Das neue Verfahren weist eine Reihe von Vorteilen auf. Die Fixierwicklung, ggfs. mit anschließender Reservewicklung, und die Spule können reproduzierbar nach Lagen und Fadenlängen entsprechend den Wünschen der Anwender genau festgelegt und eingehalten werden. Dabei kann es darauf ankommen, durch den Spulenwechsel beeinträchtigtes Spulgut mit Sicherheit in der Fixierwicklung festzuhalten, die Reservewicklung z: B. aus unverändertem Spulgut zu bilden, ebenso wie die Spule. Bei dem neuen Verfahren erübrigt sich die Anordnung und der entsprechende maschinelle Aufwand für den Antrieb eines zweiten und dritten Fadenführers aus dem Stand der Technik, die beim Spulenwechsel mit dem Faden in Berührung kommen. Durch die insoweit reduzierte Anzahl der Teile für den Fadentransfer ergeben sich auch weniger Reibungspunkte für das Spulgut. Das Spulgut wird schonender umgelenkt. Weiterhin entfallen Probleme, die mit dem Austritt und Wiedereintritt des Fadens in den Changierfadenführer beim Stand der Technik vorhanden sind. Vorteilhaft wird auch eine mehrfädige Arbeitsweise möglich, da das Spulgut den Changierfadenführer nicht mehr verlassen muss, auch bei der Bildung der Fixierwicklung und der Reservewicklung.The new method has a number of advantages. The fixing winding, if necessary with subsequent reserve winding, and the bobbin can be reproduced reproducibly according to layers and thread lengths according to the wishes of the user precisely defined and adhered to. It may be important to hold by the bobbin exchange impaired Spulgut with certainty in the fixing winding to form the reserve winding z: B. from unchanged Spulgut, as well as the coil. In the new method, the arrangement and the corresponding mechanical effort for the drive of a second and third yarn guide from the prior art, which come into contact with the yarn during the bobbin change, is superfluous. Due to the extent reduced number of parts for the thread transfer also results in fewer points of friction for the Spulgut. The Spulgut is deflected gentler. Furthermore, eliminates problems that exist with the exit and reentry of the thread in the traversing yarn guide in the prior art. Advantageously, a multi-thread operation is possible because the Spulgut no longer has to leave the traversing yarn guide, even in the formation of the fixing winding and the reserve winding.

Zur einstellbaren Festlegung der Lage und der Fadenlänge der Fixierwicklung kann die Drehzahl der Kehrgewindewelle derart geregelt oder auch auf zumindest angenähert Null abgebremst werden, dass der Changierfadenführer die ausgewählte Relativlage zur Verlegebreite der Spulspindel einnimmt. Damit können in üblicher Weise ausgebildete Kehrgewindewellen mit Verlegenut eingesetzt werden. Die zusätzliche Anordnung eines steigungslosen Nutabschnittes und einer Weiche wird grundsätzlich entbehrlich. Bei einer auf eine Drehzahl Null abgebremsten und festgesetzten Kehrgewindewelle steht der Changierfadenführer genau an der ausgewählten Stelle innerhalb der Verlegebreite, und es ist nur noch von der Zeit abhängig, mit welcher Fadenlänge die Fixierwicklung ortsgenau aufgebracht wird. Da die Verlegenut in der Kehrgewindewelle Umlenkungen aufweist, die eine vergleichsweise geringe Steigung besitzen, können diese Bereiche auch ohne genaues Erreichen der Drehzahl 0 zumindest für Fixierwicklungen geringer Fadenlänge genutzt werden. Wenn die Fixierwicklung nicht innerhalb der Verlegebreite oder in einem der beiden Endbereiche der Spule, sondern außerhalb der Verlegebreite oder der Spulenbreite, angebracht werden soll, was überwiegend der Fall ist, ist die Axialverschiebung der Changiereinrichtung in Spulspindelrichtung erforderlich. Diese Verschiebung wird variabel einstellbar oder steuerbar gestaltet, so dass die genaue Lage der Fixierwicklung relativ zur Spule auf der Hülse auswählbar und damit zur Wicklung unterschiedlicher Spulen unterschiedlich festlegbar ist. Es entfällt auch die Notwendigkeit, einen reversierbaren Motor für den Antrieb der Kehrgewindewelle einzusetzen.For adjustable definition of the position and the thread length of the fixing winding, the speed of the Kehrgewindewelle can be regulated or braked to at least approximately zero, that the traversing yarn assumes the selected relative position to the laying width of the winding spindle. This can be used with laying groove trained in the usual way Kehrgewindewellen. The additional arrangement of an unpolluted groove portion and a switch is basically unnecessary. In a decelerated to a speed zero and fixed Kehrgewindewelle the traversing yarn guide is exactly at the selected location within the laying width, and it is only dependent on the time, with which thread length the fixing winding is applied location accurate. Since the laying channel in the counter-rotating shaft has deflections which have a comparatively small pitch, these areas can also be used without accurate attainment of the rotational speed 0, at least for fixing windings of short thread length. If the fixing winding is not to be mounted within the laying width or in one of the two end regions of the bobbin, but outside the laying width or the bobbin width, which is predominantly the case, the axial displacement of the traversing device in the winding spindle direction is required. This shift is made variably adjustable or controllable, so that the exact position of the fixing winding relative to the coil on the sleeve selectable and thus different for winding different coils can be fixed. It also eliminates the need to use a reversible motor for driving the Kehrgewindewelle.

Eine beliebige räumliche Position des angetriebenen Changierfadenführers der Changiereinrichtung kann mit einem ersten Sensor erfasst, gespeichert und als Referenzposition bei der Bildung der Fixierwicklung, ggfs. der Reservewicklung, und der Spule genutzt werden. Damit wird der Beginn eines Steuer- bzw. Regelablaufs und damit die Spulreise festgelegt. Zu diesem Zweck kann ein erster Sensor zu einem beliebigen Zeitpunkt aktiviert werden. Der Sensor überwacht und erfasst den Weg des angetriebenen Changierfadenführers. Er legt gleichzeitig mit der Feststellung einer Raumposition des Changierfadenführers den Beginn einer Zeit fest und bildet damit eine Referenzposition, um sich im Verlauf der Spulreise immer wieder darauf zu beziehen und so eine Aussage treffen zu können, wo sich während der Spulreise der Changierfadenführer gerade befindet.Any spatial position of the driven traversing yarn guide of the traversing device can be detected with a first sensor, stored and used as a reference position in the formation of the fixing winding, if necessary. The reserve winding, and the coil. This determines the beginning of a control process and thus the winding travel. For this purpose, a first sensor can be activated at any time. The sensor monitors and detects the path of the driven traversing yarn guide. He sets simultaneously with the determination of a spatial position of the traversing yarn guide the beginning of a time and thus forms a reference position in order to relate to it during the winding cycle again and again to make a statement where the traversing yarn guide is currently located during the winding cycle.

Es ist aber auch möglich, nach jedem Spulenwechsel eine Startposition anzufahren, in der die räumliche Lage des Changierfadenführers bekannt bzw. festgelegt ist und die dann den Beginn einer Spulreise darstellt. Eine solche Startposition kann mit einem Absolutwertgeber oder einem Inkrementalgeber detektiert bzw. angefahren werden.But it is also possible after each bobbin change to approach a starting position in which the spatial position of the traversing yarn guide is known or fixed and which then represents the beginning of a winding cycle. Such a start position can be detected or approached with an absolute encoder or an incremental encoder.

Insbesondere bei Präzisionswicklung kann vorteilhaft die Drehzahl der Kehrgewindewelle mit einem zweiten Sensor zeitlich kontinuierlich erfasst werden. Bei Präzisionswicklung ändert sich bekanntlich das Spulverhältnis über die Spulreise und damit die Drehzahl der Kehrgewindewelle. Durch Erfassung der Veränderung der Kehrgewindewelle kann genau festgelegt werden, in Relation zu der Referenzposition, an welcher Stelle sich zu welcher Zeit der Changierfadenführer relativ zur Spulspindel befindet. Man kann auch ohne den zweiten Sensor auskommen. Es ist dann möglich, den ersten Sensor wiederholt zu nutzen und aus dessen Signalen bei bekannter Geometrie der Verlegenut auf die räumliche Lage des Changierfadenführers über einen Doppelhub zu schließen. Besonders einfach wird dies, wenn die Drehzahl der Kehrgewindewelle zwischen zwei Signalen konstant gehalten wird.In particular, in the case of precision winding, the rotational speed of the counter-twisting shaft can advantageously be detected continuously in time with a second sensor. With precision winding, it is known to change the winding ratio over the winding cycle and thus the speed of the counter-twisting shaft. By detecting the change in the counterbore shaft can be accurately determined, in relation to the reference position, at which point at which time the traversing thread guide is relative to the winding spindle. You can also do without the second sensor. It is then possible to repeatedly use the first sensor and to close its signals with known geometry of the laying channel on the spatial position of the traversing yarn guide over a double stroke. This becomes particularly simple if the speed of the counter-clockwise shaft between two signals is kept constant.

Eine Spulmaschine zum Aufwickeln eines kontinuierlich zulaufenden Fadens auf einer Hülse zu einer Spule, unter Bildung einer Fixierwicklung, ggfs. mit anschließender Reservewicklung, und der Spule, insbesondere nach dem Verfahren des Anspruchs 1 oder 2, ist an sich zunächst üblich aufgebaut. Sie kennzeichnet sich erfindungsgemäß dadurch, dass das Signal des ersten Sensors oder eines entsprechenden Elements der einmalig erfassten räumlichen Position des angetriebenen Changierfadenführers der Changiereinrichtung der Regeleinrichtung zugeleitet, dort in zeitlicher Zuordnung gespeichert und als Referenzposition bei der Bildung der Fixierwicklung, ggfs. mit anschließender Reservewicklung, und der Spule genutzt wird, und dass die Regeleinrichtung zur Generierung räumlicher Positionen, an denen sich der Changierfadenführer der Changiereinrichtung über die Spulreise gerade befindet, aus der Referenzposition und zum Abstimmen auf die Spulgeschwindigkeit ausgebildet ist.A winding machine for winding a continuously tapered thread on a sleeve to form a coil, with the formation of a fixing winding, if necessary. With subsequent reserve winding, and the coil, in particular according to the method of claim 1 or 2, is initially customary per se. It is characterized according to the invention in that the signal of the first sensor or a corresponding element of the once detected spatial position of the driven traversing yarn guide the traversing device supplied to the control device, stored there in temporal association and as a reference position in the formation of the fixing winding, if necessary. With subsequent reserve winding, and the coil is used, and that the control device for generating spatial positions at which the traversing yarn guide of the traversing device is just above the winding cycle, formed from the reference position and for tuning to the winding speed.

Wenn eine Fixierwicklung mit anschließender Reservewicklung, also außerhalb der Spulenbreite, gebildet werden sollen, ist ein steuerbarer Antrieb zum zeitlich geregelten Verfahren der Changiereinrichtung mit dem Changierfadenführer in Spulspindelrichtung vorgesehen ist. Die Regeleinrichtung ist so ausgebildet, dass die axiale Bewegung der Changiereinrichtung in Relation zu den räumlichen Positionen des Changierfadenführers der Changiereinrichtung über die Spulreise so geregelt wird, dass auf der Hülse nacheinander die Fixierwicklung, die Reservewicklung und die Spule nach Lage und Fadenlänge festgelegt und gebildet werden.If a fixing winding with subsequent reserve winding, that is to say outside the coil width, are to be formed, a controllable drive is provided for the temporally regulated method of the traversing device with the traversing thread guide in the winding spindle direction. The control device is designed so that the axial movement of the traversing device is controlled in relation to the spatial positions of the traversing thread guide of the traversing over the winding cycle so that on the sleeve successively the fixing winding, the reserve winding and the coil are determined and formed according to location and thread length ,

Wesentlich ist zunächst einmal ein erster Sensor oder ein entsprechendes Element, der in aller Regel im oder am Gehäuse der Changiereinrichtung angeordnet wird, um so den Hub des Changierfadenführers zu überwachen und festzustellen, zu welchem Zeitpunkt der Changierfadenführer eine räumliche Position durchläuft. Zu diesem Zeitpunkt wird ein Signal gebildet. Der Zeitpunkt wird festgehalten und das Signal einer Regeleinrichtung zugeleitet. Damit ist eine Referenzposition festgelegt, die bei der Bildung der Fixierwicklung, ggfs. der Reservewicklung, und der Spule genutzt wird. Die Regeleinrichtung ist nun so ausgestaltet, dass sie in Abhängigkeit von dieser festgelegten Referenzposition zu jedem Zeitpunkt in der Lage ist, eine Aussage über die jeweilige räumliche Position des Changierfadenführers relativ zur Spulspindel zu machen. Es ist damit nicht nur möglich, eine Aussage darüber zu machen, wo sich der Changierfadenführer zu einem bestimmten Zeitpunkt befindet, sondern sogar vorauszuberechnen, wo sich der Changierfadenführer zu einem Zeitpunkt in der Zukunft befinden wird, freilich abgestimmt auf die Drehzahl der Kehrgewindewelle.It is essential first of all a first sensor or a corresponding element, which is usually arranged in or on the housing of the traversing device, so as to monitor the stroke of the traversing yarn guide and determine at which time the traversing yarn guide passes through a spatial position. At this time, a signal is formed. The time is recorded and the signal is sent to a control device. Thus, a reference position is set, which is used in the formation of the fixing winding, possibly the reserve winding, and the coil. The control device is now designed so that it is able to make a statement about the respective spatial position of the traversing yarn guide relative to the winding spindle in response to this fixed reference position at any time. It is thus not only possible to make a statement as to where the traversing yarn guide is at a particular point in time, but even to predict where the traversing yarn guide will be at a time in the future, albeit adapted to the speed of the counter-shaft.

Es ist ein steuerbarer Antrieb zum Verfahren der Changiereinrichtung in Spulspindelrichtung vorgesehen, wobei es darauf ankommt, letztlich den Changierfadenführer in eine bestimmte räumliche Position außerhalb der Verlegebreite zu bringen. Dabei ist es von untergeordneter Bedeutung, ob die gesamte Changiereinrichtung, also einschließlich deren Gehäuse, oder nur die Kehrgewindewelle in dem Gehäuse axial in Spulspindelrichtung bewegt werden. Diese axiale Beweglichkeit der Changiereinrichtung bzw. des Changierfadenführers dient zum Erreichen von Positionen, die an sich außerhalb des durch die Verlegenut abgedeckten Normalbereiches angeordnet sind. So kann insbesondere die Fixierwicklung am einen oder anderen Ende mit Abstand zu der zu platzierenden Spule vorgesehen sein. Oft wird dieser Abstand je nach Anwendungsfall und Art der eingesetzten Hülsen auch veränderlich gewünscht. Entsprechendes gilt dann für die Reservewicklung, die zwar in der Regel den Abstand zwischen der Fixierwicklung und der Spule ausfüllt, aber im Einzelfall auch gesondert und insbesondere mit unterschiedlicher Fadenlänge gebildet werden kann.It is a controllable drive for moving the traversing device provided in Spulspindelrichtung, wherein it is important to ultimately bring the traversing yarn guide in a specific spatial position outside the laying width. It is of minor importance, whether the entire traversing device, including the housing, or only the Kehrgewindewelle be moved axially in the winding spindle direction in the housing. This axial mobility of the traversing device or of the traversing yarn guide serves to reach positions that are arranged on the outside of the normal region covered by the laying groove. Thus, in particular, the fixing winding may be provided at one end or the other at a distance from the coil to be placed. Often this distance is also desired depending on the application and the type of sleeves used. The same applies to the reserve winding, which, although usually fills the distance between the fixing winding and the coil, but in individual cases can be formed separately and in particular with different thread length.

Für die Realisierung einer solchen Spulmaschine kann in wesentlichen Elementen unverändert auf den Stand der Technik zurückgegriffen werden. Dies gilt insbesondere für die Anordnung von zwei Spulspindeln auf einem Drehteller, die Ausbildung der Changiereinrichtung mit Kehrgewindewelle mit Verlegenut und einem oder mehreren Changierfadenführern. Der Changierfadenführer kann für einfädiges oder mehrfädiges Arbeiten ausgebildet sein. Wichtig ist für eine Reservewicklung ein zusätzlicher Antrieb für eine Axialverschiebung des Changierfadenführers in Spulspindelrichtung sowie dessen Steuerung über eine Regeleinrichtung, die die räumliche Zuordnung der Positionen des Changierfadenführers zu der Hülse auf der Spulspindel kennt bzw. regelt.For the realization of such a winding machine can be used in essential elements unchanged on the state of the art. This is especially true for the arrangement of two winding spindles on a turntable, the formation of the traversing device with Kehrgewindewelle with laying groove and one or more traversing yarn guides. The traversing yarn guide can be designed for single-thread or multi-thread work. It is important for a reserve winding an additional drive for an axial displacement of the traversing thread guide in Spulspindelrichtung and its control via a control device that knows or regulates the spatial assignment of the positions of the traversing yarn guide to the sleeve on the winding spindle.

Vorteilhaft ist es, wenn ein zweiter Sensor zur kontinuierlichen Erfassung der Drehzahl der Kehrgewindewelle über die Zeit vorgesehen ist. Auch dieses Signal des zweiten Sensors wird der Regeleinrichtung zugeleitet, so dass in Verbindung mit der Referenzposition zu jedem Zeitpunkt bekannt ist, wo sich der Changierfadenführer relativ zur Spulspindel befindet.It is advantageous if a second sensor is provided for the continuous detection of the speed of the Kehrgewindewelle over time. Also, this signal of the second sensor is supplied to the control device, so that in conjunction with the reference position to It is known at any time where the traversing yarn guide is relative to the winding spindle.

Für die Realisierung des ersten und des zweiten Sensors ergeben sich verschiedene Möglichkeiten.For the realization of the first and the second sensor, there are various possibilities.

Zur einmaligen Erfassung einer räumlichen Position des angetriebenen Changierfadenführers der Changiereinrichtung als erster Sensor kann mindestens eines der folgenden Elemente vorgesehen sein:

  1. a) ein berührungslos arbeitender Näherungssensor,
  2. b) ein Absolutwertgeber,
  3. c) eine Einrichtung zum Einstellen einer vorher festgelegten Referenzposition.
For a single detection of a spatial position of the driven traversing yarn guide of the traversing device as the first sensor, at least one of the following elements can be provided:
  1. a) a non-contact proximity sensor,
  2. b) an absolute encoder,
  3. c) means for setting a predetermined reference position.

Zur Ermittlung des zeitlichen Verlaufs der räumlichen Positionen des Changierfadenführers über die Spulreise als zweiter Sensor kann eines oder mehrere der folgenden Elemente vorgesehen sein:

  1. a) ein Inkrementalgeber, insbesondere auf dem Motor des Antriebes der Kehrgewindewelle,
  2. b) ein Resolver,
  3. c) ein berührungslos arbeitender Näherungssensor,
  4. d) ein Tachometer,
  5. e) eine Zeitmesseinrichtung,
  6. f) ein Absolutwertgeber.
To determine the time course of the spatial positions of the traversing yarn guide over the winding cycle as a second sensor, one or more of the following elements may be provided:
  1. a) an incremental encoder, in particular on the motor of the drive of the counter-rotating shaft,
  2. b) a resolver,
  3. c) a non-contact proximity sensor,
  4. d) a speedometer,
  5. e) a time measuring device,
  6. f) an absolute encoder.

Auf den Spulspindeln können Hülsen eingesetzt werden, die mit einem Fangbereich ausgestattet sind. Es versteht sich, dass der Changierfadenführer in Richtung der Spulspindel so verfahrbar sein muss, dass der Faden zwischen dem Kopffadenführer und dem Fangbereich der Hülse in möglichst gerader, möglichst wenig geknickter Linie so aufgespannt wird, dass beim automatischen Spulenwechsel sich der Faden in dem Fangbereich der Leerhülse verfängt. Sobald dieses Verfangen festgestellt worden ist, kann die Position angefahren werden, in der die Fixierwicklung gebildet werden soll. Die Fixierwicklung kann auch so gelegt werden, dass der Fangbereich überwickelt wird.On the winding spindles sleeves can be used, which are equipped with a catching area. It is understood that the traversing yarn guide in the direction of the winding spindle must be movable so that the thread between the head thread guide and the catching area of the sleeve is stretched in as straight as possible with little kinked line so that the automatic bobbin change the thread in the capture area of the Empty tube caught. Once this snagging has been detected, the position can be approached in which the fixing winding is to be formed. The fixing winding can also be placed so that the catching area is wrapped.

In den Zeichnungen sind nur die für das Verständnis der Erfindung wesentlichen Teile der Spulmaschine angegeben. Die Spulmaschine besitzt einen Rahmen 1, an dem ein Kopffadenführer 2 ortsfest angeordnet ist. Dem Kopffadenführer 2 läuft ein Faden 3 zu, dessen Verlegedreieck 4 strichpunktiert angedeutet ist.In the drawings, only the essential parts for understanding the invention of the winder are given. The winder has a frame 1, on which a head thread guide 2 is arranged stationary. The head thread guide 2 runs to a thread 3, the laying triangle 4 is indicated by dash-dotted lines.

Am Rahmen 1 ist ein Drehteller 5 in bekannter Weise um eine Achse 6 drehbar gelagert. Der Drehteller 5 wird in bekannter Weise beim Spulenwechsel gedreht angetrieben. Auf dem Drehteller 5 sind zwei Spulspindeln 7 und 8 drehbar gelagert und in der Betriebsstellung des Drehtellers 5 jeweils mit einem Antrieb kuppelbar, über den die betreffenden Spulspindeln 7 und/oder 8 angetrieben werden. Die Spulspindel 7 gemäß Fig. 1 befindet sich in der Betriebsposition und wird demgemäß angetrieben. Auf jeder Spulspindel 7, 8 sitzt eine Hülse 9, auf der der Faden 3 zu einer Spule 10 aufgewickelt wird.On the frame 1, a turntable 5 is rotatably mounted about an axis 6 in a known manner. The turntable 5 is driven rotated in a known manner during bobbin change. On the turntable 5, two winding spindles 7 and 8 are rotatably mounted and can be coupled in the operating position of the turntable 5 each with a drive via which the respective winding spindles 7 and / or 8 are driven. The winding spindle 7 according to Fig. 1 is in the operating position and is driven accordingly. On each winding spindle 7, 8 sits a sleeve 9, on which the thread 3 is wound into a coil 10.

An dem Rahmen 1 der Spulmaschine ist eine Changiereinrichtung 11 vorgesehen. Die Changiereinrichtung 11 weist ein Gehäuse 12 auf, welches um eine Achse 13 schwenkbar am Rahmen 1 der Spulmaschine gelagert ist, damit sich die Changiereinrichtung 11 während dem über die Spulreise wachsenden Spulendurchmesser (Fig. 3) anpassen kann. In dem Gehäuse 12 der Changiereinrichtung 11 ist eine Kehrgewindewelle 14 drehbar gelagert, die in üblicher Weise angetrieben wird. Die Kehrgewindewelle 14 weist auch eine übliche endlose Kehrgewindenut auf, mit deren Hilfe ein Changierfadenführer 15 hin- und hergehend angetrieben wird, und zwar über die Changier-, Spulen- oder Verlegebreite, die die Breite der Spule 10 bestimmt. Für den Antrieb der Kehrgewindewelle 14 ist ein Motor 16 vorgesehen, dessen Drehzahl über eine Regeleinrichtung 17 ausgesteuert wird.On the frame 1 of the winder a traversing device 11 is provided. The traversing device 11 has a housing 12, which is mounted pivotably about an axis 13 on the frame 1 of the winding machine, so that the traversing device 11 during the growing over the winding cycle Spulendurchmesser ( Fig. 3 ). In the housing 12 of the traversing device 11 a Kehrgewindewelle 14 is rotatably mounted, which is driven in the usual manner. The Kehrgewindewelle 14 also has a conventional endless Kehrgewindenut, with the help of a traversing yarn 15 is reciprocally driven, via the traversing, coil or laying width, which determines the width of the coil 10. For the drive of the Kehrgewindewelle 14, a motor 16 is provided, whose speed is controlled by a control device 17.

Es ist eine Fangeinrichtung 18 vorgesehen, um zu Beginn eines Spulenaufbaus den Faden 3 zu fangen. Die Fangeinrichtung 18 kann entweder an jeder Spulspindel 7, 8 dauerhaft und damit unabhängig von einer Hülse 9 angebracht sein. Es ist aber auch möglich, als Fangeinrichtung solche Elemente zu nutzen, die an jeder Hülse vorgesehen sind, also eine entsprechende Fangkerbe, Fangvertiefung o. dgl.. Am Gehäuse 12 der Changiereinrichtung 11 ist schließlich noch eine Kontaktwalze 19 (Fig. 3) gelagert, über die der Faden 3 auf der Oberfläche der sich bildenden Spule 10 angelegt wird. Die Kontaktwalze 19 ist in den übrigen Figuren aus Übersichtlichkeitsgründen weggelassen. Die Schnittangabe I-I in Fig. 3 verdeutlicht die Darstellung der Fig. 1.A catching device 18 is provided in order to catch the thread 3 at the beginning of a package construction. The catcher 18 can either permanently on each winding spindle 7, 8 and thus independent of a Sleeve 9 may be attached. But it is also possible to use such elements as catching device, which are provided on each sleeve, so a corresponding catch notch, catch recess o. The like .. At the housing 12 of the traversing device 11 is finally a contact roller 19 ( Fig. 3 ), over which the thread 3 is applied to the surface of the forming coil 10. The contact roller 19 is omitted in the other figures for reasons of clarity. The section II in Fig. 3 clarifies the representation of the Fig. 1 ,

Fig. 1 zeigt die Spulmaschine zu einem Zeitpunkt während der Spulreise, bei der der Durchmesser der Spule 10 auf der Hülse 9 der in Betrieb befindlichen Spulspindel 7 bereits relativ weit angewachsen ist. Es ist auch angedeutet, dass auf der Hülse 9 nach dem Fangen des Fadens 3 zunächst eine Fixierwicklung 20, dann eine Reservewicklung 21 und schließlich die Spule 10 aufgewickelt worden ist. Bei der Fixierwicklung 20 handelt es sich um mehrere dicht nebeneinander und/oder übereinander liegende Wicklungen des Fadens 3. Die Reservewicklung 21 schließt an die Fixierwicklung 20 an und erstreckt sich mit einer gewindeartigen Verlegung des Fadens 3 bis zur Stirnwand der gebildeten Spule 10. Diese Verhältnisse sind anhand der Fig. 10 noch einmal verdeutlicht. Eine solche Fixierwicklung 20 kann unmittelbar benachbart zu der Fangeinrichtung 18 auf der Hülse 9 angeordnet sein, aber auch in jeder sonstigen axial festgelegten Position relativ zur Breite der Hülse 9. Eine Reservewicklung 21 tritt nur dann auf, wenn die Fixierwicklung 20 außerhalb der Verlegebreite der Spule 10 vorgesehen ist. Unter einer Fixierwicklung 20 wird aber auch eine solche Wicklung verstanden, die innerhalb der Verlegebreite der Spule 10 vorgesehen ist. Fig. 1 shows the winder at a time during the winding cycle, in which the diameter of the coil 10 on the sleeve 9 of the winding spindle 7 in operation has already grown relatively far. It is also indicated that on the sleeve 9 after catching the thread 3, first a fixing winding 20, then a reserve winding 21 and finally the coil 10 has been wound. The fixing winding 20 is a plurality of closely juxtaposed and / or superimposed windings of the thread 3. The reserve winding 21 connects to the fixing winding 20 and extends with a thread-like laying of the thread 3 to the end wall of the formed coil 10. These conditions are based on the Fig. 10 once again clarified. Such a fixing winding 20 may be disposed immediately adjacent to the catching device 18 on the sleeve 9, but also in any other axially fixed position relative to the width of the sleeve 9. A reserve winding 21 only occurs when the fixing winding 20 outside the laying width of the coil 10 is provided. However, a fixing winding 20 is also understood as meaning a winding which is provided within the laying width of the coil 10.

Fig. 1 lässt weiterhin erkennen, dass an der Changiereinrichtung 11 ein erster Sensor 22 vorgesehen ist. Dieser erste Sensor 22 dient zum Erfassen der Position des Changierfadenführers 15. Der erste Sensor 22 ist über eine elektrische Leitung 23 mit der Regeleinrichtung 17 verbunden. Über die Leitung 23 werden die Signale des ersten Sensors 22 der Regeleinrichtung 17 zugeführt. Wenn der erste Sensor 22 beispielsweise als berührungsloser Näherungssensor ausgebildet ist, kann mit ihm relativ zu seiner Anordnung am Gehäuse 12 der Changiereinrichtung 11 festgestellt werden, wann der Changierfadenführer 15 z. B. seinen Umkehrpunkt über die Spulreise erreicht. Damit wird eine Referenzposition des Changierfadenführers 15 festgelegt, gebildet und in der Regeleinrichtung 17 abgespeichert. Dies zielt darauf ab, während der Spulreise einen Bezugspunkt zu haben, mit dem in Verbindung mit weiteren Elementen über die gesamte Spulreise feststellbar und festlegbar ist, wo sich gerade der Changierfadenführer 15 befindet. Fig. 1 Furthermore, it can be seen that a first sensor 22 is provided on the traversing device 11. This first sensor 22 is used to detect the position of the traversing yarn guide 15. The first sensor 22 is connected via an electrical line 23 to the control device 17. Via the line 23, the signals of the first sensor 22 of the control device 17 are supplied. If the first sensor 22 is formed, for example, as a non-contact proximity sensor, it can be determined with him relative to its arrangement on the housing 12 of the traversing device 11, when the traversing yarn guide 15 z. B. reaches its reversal point on the winding cycle. Thus, a reference position of the traversing yarn guide 15 is set, formed and stored in the control device 17. This aims to have a reference point during the winding cycle, with which in connection with other elements over the entire winding cycle is detectable and fixable, where just the traversing yarn guide 15 is located.

Das Erfassen der Position des Changierfadenführers 15 kann auch für mehrere Spulreisen vor Beginn der ersten Spulreise und vor der Anlieferung des Fadens nach Anlegen einer Steuerspannung an die Spulmaschine erfolgen. Eine Wiederholung bei jeder Spulreise ist damit nicht erforderlich.The detection of the position of the traversing yarn guide 15 can also be done for several winding cycles before the start of the first winding cycle and before the delivery of the yarn after applying a control voltage to the winder. A repetition at each winding travel is not required.

An der Changiereinrichtung 11 ist weiterhin ein zweiter Sensor 24 angeordnet, von dem ebenfalls eine elektrische Leitung 25 zu der Regeleinrichtung 17 führt. Der zweite Sensor 24 dient zur Überwachung, Ermittlung und Erfassung der Drehzahl der Kehrgewindewelle 14 während der Spulreise. Damit ist die Möglichkeit geschaffen, zu jedem Zeitpunkt der Spulreise festzustellen, an welcher Stelle sich gerade der Changierfadenführer 15 befindet.At the traversing device 11, a second sensor 24 is further arranged, from which also an electrical line 25 leads to the control device 17. The second sensor 24 is used to monitor, detect and detect the speed of the Kehrgewindewelle 14 during the winding cycle. This creates the opportunity to determine at any time of the winding cycle, at which point just the traversing yarn guide 15 is located.

Von der Regeleinrichtung 17 führt eine Steuerleitung 26 zu dem Motor 16, der die Kehrgewindewelle 14 antreibt. Über diese Steuerleitung 26 kann die Drehzahl der Kehrgewindewelle gesteuert verändert werden. Die Drehzahl kann so gezielt vermindert, auf 0 gestellt oder in einer bestimmten Größe eingeregelt werden. Es ist vorstellbar, dass die Fixierwicklung 20 an der gewünschten Stelle relativ zur Spulspindelrichtung 27 auf der Hülse 9 gebildet werden kann. Die Fixierwicklung 20 kann insoweit außerhalb der Verlegebreite der Spule 10 oder auch innerhalb der Verlegebreite 10 angeordnet werden. Die Fig. 1 und 2 zeigen ein Ausführungsbeispiel, bei dem die Fixierwicklung 20 und die Reservewicklung 21 außerhalb der Verlegebreite auf der linken Seite der Hülse 9 vorgesehen sind.From the control device 17, a control line 26 leads to the motor 16, which drives the Kehrgewindewelle 14. About this control line 26, the speed of the Kehrgewindewelle can be changed controlled. The speed can be selectively reduced, set to 0 or adjusted in a certain size. It is conceivable that the fixing winding 20 can be formed on the sleeve 9 at the desired location relative to the winding spindle direction 27. The fixing winding 20 can be arranged so far outside the laying width of the coil 10 or within the laying width 10. The Fig. 1 and 2 show an embodiment in which the fixing winding 20 and the reserve winding 21 are provided outside the laying width on the left side of the sleeve 9.

Wie insbesondere aus einem Vergleich der Fig. 1 und 2 hervorgeht, ist das Gehäuse 12 der Changiereinrichtung 11 nicht nur um die Achse 13 schwenkbar, sondern zusätzlich in Richtung der Achse 13 axialverschiebbar. Dies zielt darauf ab, den Changierfadenführer 15 für eine gewisse Zeit auch außerhalb der Verlegebreite zu positionieren. Zu diesem Zweck ist ein Antrieb 28 vorgesehen, der hier als Kolben/Zylinder-Einheit 29 ausgebildet ist, dessen Kolbenstange mit dem Gehäuse 12 der Changiereinrichtung 11 verbunden ist. Es ist ein Ventil 30 vorgesehen, welches beispielsweise als pneumatisches Schaltventil ausgebildet und mit einer Druckluftversorgung verbunden ist. Das Ventil 30 wird von der Regeleinrichtung 17 über eine elektrische Leitung 31 angesteuert. Von dem Ventil 30 führen pneumatische Leitungen 32 und 33 zu der Kolben/Zylinder-Einheit 29.As in particular from a comparison of Fig. 1 and 2 shows, the housing 12 of the traversing device 11 is not only pivotable about the axis 13, but also axially displaceable in the direction of the axis 13. This aims to position the traversing yarn guide 15 for a certain time outside the laying width. For this purpose, a drive 28 is provided, which is designed here as a piston / cylinder unit 29, whose piston rod is connected to the housing 12 of the traversing device 11. It is a valve 30 is provided, which is formed for example as a pneumatic switching valve and connected to a compressed air supply. The valve 30 is controlled by the control device 17 via an electrical line 31. From the valve 30, pneumatic lines 32 and 33 lead to the piston / cylinder unit 29.

Damit ist es möglich, die Changiereinrichtung 11 und insbesondere den Changierfadenführer 15 axial in Richtung der Achse 13 bzw. in Spulspindelrichtung 27 über die Regeleinrichtung 17 zu einem beliebig wählbaren Zeitpunkt gezielt zu verfahren. Fig. 2 zeigt eine solche eingesteuerte Relativlage, bei der sich der Changierfadenführer 15 in einer solchen Position befindet, dass der Faden 3 von der Fangeinrichtung 18 an der Hülse 9 erfasst werden kann. Sobald der Faden 3 von der Fangeinrichtung 18 erfasst ist, wird über die Regeleinrichtung 17 der Antrieb 28 angesteuert, während der Motor 16 für den Antrieb der Kehrgewindewelle 14 weiterhin beispielsweise abgebremst ist. Die Axialverschiebung der Changiereinrichtung 11 mit dem Changierfadenführer 15 wird dann in einer solchen Stellung in Spulspindelrichtung 27 beendet, an der die Fixierwicklung 20 auf die Hülse 9 aufgebracht werden soll. Dies kann nicht nur bei stillstehender Kehrgewindewelle 14 erfolgen, sondern auch in Abhängigkeit von einer gezielten langsamen Drehung der Kehrgewindewelle 14, da ohnehin der Regeleinrichtung 17 die Position des Changierfadenführers 15 zu jedem Zeitpunkt der Spulreise bekannt ist. Über die Länge der Dauer, in der der Changierfadenführer 15 in Spulspindelrichtung 27 stillsteht, wird die Fadenlänge bestimmt, die auf der sich drehenden Spulspindel 7 mit der Hülse 9 aufgewickelt wird.This makes it possible to move the traversing device 11 and in particular the traversing yarn guide 15 axially in the direction of the axis 13 or in the winding spindle direction 27 via the control device 17 at an arbitrarily selectable time. Fig. 2 shows such a controlled relative position, in which the traversing yarn guide 15 is in a position such that the thread 3 can be detected by the catching device 18 on the sleeve 9. As soon as the thread 3 is detected by the catching device 18, the drive 28 is actuated via the control device 17, while the motor 16 for driving the reverse thread shaft 14 continues to be braked, for example. The axial displacement of the traversing device 11 with the traversing yarn guide 15 is then terminated in such a position in the winding spindle direction 27 at which the fixing winding 20 is to be applied to the sleeve 9. This can be done not only with stationary counterclockwise shaft 14, but also in response to a targeted slow rotation of the reverse-drive shaft 14, since anyway the control device 17, the position of the traversing yarn guide 15 at each time the winding cycle is known. Over the length of the duration in which the traversing yarn guide 15 is stopped in the winding spindle direction 27, the yarn length is determined, which is wound on the rotating winding spindle 7 with the sleeve 9.

Anschließend wird die Reservewicklung 21 gebildet. Hierzu wird der Motor 16 der Kehrgewindewelle 14 über die Regeleinrichtung 17 entsprechend angesteuert. In der Folge bewegt sich der Changierfadenführer 15 über die axiale Länge der Reservewicklung 21, so dass diese in gewindeartiger Form des Fadens 3 auf der Hülse 9 gebildet wird.Subsequently, the reserve winding 21 is formed. For this purpose, the motor 16 of the Kehrgewindewelle 14 is controlled accordingly via the control device 17. As a result, the traversing yarn guide 15 moves over the axial length of the reserve winding 21, so that it is formed in a thread-like shape of the yarn 3 on the sleeve 9.

Nach Beendigung der Reservewicklung beginnt der Aufbau der Spule 10. Hierzu wird der Antrieb der Spulspindel 7 und der Motor 16 auf die vorgesehenen Drehzahlen beschleunigt und gleichzeitig der Antrieb 28 für die Axialverschiebung des Changierfadenführers 15 in seine normale Ausgangslage (Fig. 1) zurückgeführt.After completion of the reserve winding of the structure of the coil 10 begins. For this purpose, the drive of the winding spindle 7 and the motor 16 is accelerated to the intended speeds and at the same time the drive 28 for the axial displacement of the traversing yarn guide 15 in its normal starting position ( Fig. 1 ) returned.

Fig. 3 verdeutlicht die räumliche Anordnung des Kopffadenführers 2, des Drehtellers 5, der Changiereinrichtung 11 und der beiden Spulspindeln 7 und 8 gemäß Fig. 1. Fig. 2 zeigt die Teile nach einem Spulenwechsel, so dass die Spulspindeln 7 und 8 ihre Rolle vertauscht haben und auf der Hülse 9 der nunmehr im Betrieb befindlichen Spulspindel 8 die neue Spulreise durch Fangen des Fadens 3 mit der Fangeinrichtung 18 beginnt. Fig. 3 illustrates the spatial arrangement of the head thread guide 2, the turntable 5, the traversing device 11 and the two winding spindles 7 and 8 according to Fig. 1 , Fig. 2 shows the parts after a bobbin change, so that the winding spindles 7 and 8 have reversed their roles and begins on the sleeve 9 of the now in operation winding spindle 8, the new winding cycle by catching the thread 3 with the catcher 18.

Anhand der Fig. 4 und 5 wird eine weitere Ausführungsform der Spulmaschine verdeutlicht. Diese Ausführungsform baut auf der Ausführungsform der Fig. 1 und 2 auf, weshalb auf die diesbezügliche Beschreibung verwiesen werden kann. Im Gegensatz dazu fehlt hier jedoch der zweite Sensor 24. Stattdessen ist ein Zeitmesser 34 vorgesehen und mit der Regeleinrichtung 17 verbunden oder in diese integriert. Der Zeitmesser 34 gestattet es, basierend auf dem Signal des ersten Sensors zur Bildung einer Referenzposition die jeweilige Position des Changierfadenführers 15 über die Spulreise festzustellen. Der Antrieb 28 für die Axialverschiebung des Gehäuses 12 der Changiereinrichtung 11 mit dem Changierfadenführer 15 ist hier elektrisch ausgebildet. Es ist ein Elektromotor 35 vorgesehen, der eine Stellspindel 36 antreibt, um damit die Axialverschiebung der Changiereinrichtung 11 in Spulspindelrichtung 27 zu bewirken.Based on Fig. 4 and 5 a further embodiment of the winder is illustrated. This embodiment is based on the embodiment of Fig. 1 and 2 why you can refer to the description. In contrast, however, here lacks the second sensor 24. Instead, a timer 34 is provided and connected to the control device 17 or integrated into this. The timer 34 makes it possible to determine the respective position of the traversing yarn guide 15 via the winding cycle based on the signal of the first sensor to form a reference position. The drive 28 for the axial displacement of the housing 12 of the traversing device 11 with the traversing yarn guide 15 is electrically formed here. An electric motor 35 is provided which drives an adjusting spindle 36 in order to effect the axial displacement of the traversing device 11 in the winding spindle direction 27.

Auch die Ausführungsform der Fig. 6 und 7 baut auf den zuvor gezeigten Ausführungsformen auf. Im Unterschied dazu fehlen hier die beiden Sensoren 22 und 24. Stattdessen ist ein Absolutwertgeber 37 in Verbindung mit einem Zeitmesser 34 vorgesehen. Der Absolutwertgeber 37 erfasst die exakte Position des Drehwinkels der Kehrgewindewelle 14 und damit die Stellung des Changierfadenführers 15. Der Antrieb 28 für die Axialverschiebung ist hier nicht zwischen Rahmen 1 und Gehäuse 12 der Changiereinrichtung 11, sondern zwischen dem Gehäuse 12 der Changiereinrichtung und der Kehrgewindewelle 14 vorgesehen. Damit wird, wie ein Vergleich der Fig. 6 und 7 zeigt, die Kehrgewindewelle 14 mit dem Changierfadenführer 15 in Spulspindelrichtung 27 relativ zum stillstehenden Gehäuse 12 der Changiereinrichtung verschoben. Dabei muss freilich die Übertragung des Antriebs über den Motor 16 auf die Kehrgewindewelle 14 entsprechend ausgebildet sein. Es ist weiterhin erkennbar, dass die Fixierwicklung 20 sowie die Reservewicklung 21 hier am rechten Ende der Hülse 9 außerhalb der Verlegebreite der Spule 10 angeordnet sind.Also, the embodiment of Fig. 6 and 7 builds on the previously shown embodiments. In contrast, the two sensors 22 and 24 are missing here. Instead, an absolute value transmitter 37 is provided in conjunction with a timer 34. The absolute value encoder 37 detects the exact position of the angle of rotation of the counter-rotating shaft 14 and thus the position of the traversing yarn guide 15. The drive 28 for the axial displacement is not between frame 1 and housing 12 of the traversing device 11, but between the housing 12 of the traversing device and the Kehrgewindewelle 14th intended. This is how a comparison of Fig. 6 and 7 shows, the Kehrgewindewelle 14 moved with the traversing yarn guide 15 in winding spindle 27 relative to the stationary housing 12 of the traversing device. Of course, the transmission of the drive via the motor 16 must be formed in accordance with the Kehrgewindewelle 14. It can also be seen that the fixing winding 20 and the reserve winding 21 are arranged here at the right end of the sleeve 9 outside the laying width of the coil 10.

Bei der Ausführungsform der Fig. 8 und 9 ist anstelle des Absolutwertgebers 37 ein Inkrementalgeber 38 vorgesehen, und zwar in Verbindung mit einem ersten Sensor 22 und einem Zeitmesser 34. Bei dieser Ausführungsform wird keine Reservewicklung gebildet. Die Fixierwicklung wird in der Mitte der Verlegebreite angeordnet, wobei ein Hakenband 39 auf der Hülse 9 als Fangeinrichtung für den Faden 3 dient. Bei einer solchen Platzierung der Fixierwicklung 20 entfällt die Axialverschieblichkeit des Changierfadenführers 15 in Spulspindelrichtung 27 sowie der zugehörige Antrieb 28.In the embodiment of the Fig. 8 and 9 An incremental encoder 38 is provided in place of the absolute encoder 37, in conjunction with a first sensor 22 and a timer 34. In this embodiment, no reserve winding is formed. The fixing winding is arranged in the middle of the laying width, wherein a hook tape 39 on the sleeve 9 serves as a catching device for the thread 3. With such a placement of the fixing winding 20, the axial displaceability of the traversing thread guide 15 in the winding spindle direction 27 and the associated drive 28 are eliminated.

Fig. 10 verdeutlicht anhand eines Ausführungsbeispiels die Relativlage der Fixierwicklung 20 zu der Reservewicklung 21 und zu der Spule 10 anhand eines Ausführungsbeispiels einer Spulmaschine, wie sie in den Fig. 1 bis 3, aber auch den Fig. 4 und 5 dargestellt und beschrieben ist. Fig. 10 illustrated by an embodiment, the relative position of the fixing winding 20 to the reserve winding 21 and to the coil 10 based on an embodiment of a winding machine, as shown in the Fig. 1 to 3 , but also the Fig. 4 and 5 is shown and described.

Fig. 11 zeigt einen Changierfadenführer 15 mit zwei nebeneinander befindlichen Kerben für je einen Faden 3, also für zweifädige Arbeitsweise. Damit ist leicht vorstellbar, dass die Erfindung auch bei zwei- oder mehrfädiger Arbeitsweise anwendbar ist. Fig. 11 shows a traversing yarn guide 15 with two adjacent notches for each thread 3, so for two-step operation. Thus, it is easy to imagine that the invention is also applicable to two- or multi-thread operation.
