Definitions
- the invention relates to a knotting device for a thread bundle according to the preamble of claim 1.
- the invention relates to a gate with at least one warp beam storage and a gate exit, on which such a knotting device is arranged.
- DE 24 39 361 B1 shows a corresponding Knot issued with a mandrel which is hollow and has a suction opening which communicates with a suction device.
- the threads to be knotted are gathered together and wrapped around the perimeter of the mandrel. A loose end of the threads is then sucked into the mandrel and the threads are stripped off the mandrel, forming a knot.
- JP S31 1629 B1 discloses a refluxknot vibration.
- first bundles of filaments from the end of the bundle of threads wound on the warp beam and forming a plurality of second bundles of filaments from the beginning of the newly introduced bundle of threads.
- Each first bundle of fibers is then knotted with a second bundle of filaments.
- knotting for an operator is relatively tedious and exhausting.
- the invention has for its object to simplify the work for an operator at the output of a gate.
- the two filament bundles In such a knotting device, it is only necessary to arrange the two filament bundles according to the web paths. In the first path this is relatively easy, because the bundle of fibers must be arranged only in front of the suction opening. For example, if the first bundle of threads hangs down in the direction of gravity, then in many cases it is automatically positioned correctly.
- the second bundle of fibers merely has to be placed around the mandrel and thereby forms a loop or similar.
- the suction opening can be sucked by means of the suction device. If the suction opening is evacuated, so here a negative pressure is generated, then the first bundle of fibers is sucked into the suction opening and thus passes through the loop or loop, which forms the second bundle of filaments in the second path.
- the mandrel which is displaceable relative to the first web path, can then be displaced so that the first bundle of filaments is engaged with the loop or loop of the second bundle of filaments.
- the loop then only has to be tightened in order to connect the two bundles of fibers sufficiently firmly together.
- the mandrel is displaceable relative to a stripping device.
- the stripping means may strip the second bundle of filaments from the mandrel so that the loop formed by the second bundle of filaments may slip over the first bundle of filaments so that the two bundles of filaments are reliably engaged with each other.
- a throw-over device Adjacent to the mandrel, a throw-over device is arranged.
- the throw-over device can be used to push the loop formed by the second bundle of filaments over the first bundle of filaments, namely in the direction of the longitudinal extension of the first bundle of filaments in the region of the forming node, so that a cross-knot results.
- the second track path passes through a slider that is displaceable along a portion of the second track path.
- a slider which forms part of the throw-over device, the node can be tightened, so to speak.
- the end of the second bundle of filaments is folded over once, so that it is returned a distance parallel to the rest of the second bundle of filaments.
- This double bunching becomes then once pulled through the U-shaped end of the double bundle course and thus forms a loop.
- This loop is arranged in the second path.
- the slider can push the tip of the "U" over the loop, thereby creating a cross knot.
- Such a cross knot connects the two bundles of fibers with sufficient strength, so that with such a node, the second bundle of filaments can be pulled by a subsequent processing machine with the aid of the first bundle of filaments.
- the throw-over device can also have a holding bar, around which the second track path runs and which is movable relative to the first track path.
- This support bar is used to hold the loop formed by the second bundle of filaments when the second bundle of filaments is stripped off the mandrel.
- the support rod can then be guided in a direction from which the first bundle of threads tapers and thus push the loop formed by the second bundle of filaments over the first bundle of filaments. Even with this, a cross knot can be reliably obtained.
- the invention also relates to a gate with such a knotting device at the gate output.
- the operator must bring in such a gate, only the yarn bundles of the expiring yarn sheet in the correct position in front of the suction and previously arrange the filament bundles from the incoming yarn sheet in the second path.
- This activity is relatively simple and physically not exhausting.
- the knotter need only be set in operation by the suction sucks and then, when the first bundle of filaments has entered each of the suction opening, the mandrel is moved relative to the first path. It then forms on all pairings first and second thread bundle the corresponding nodes. This process is also relatively fast, so that not too much time is wasted for the change.
- a yarn sheet path is arranged between the warp beam storage and the knotting device and a fiber bundle generating device is provided, which is at least partially movable relative to the yarn sheet path.
- the thread bundle generating device With the thread bundle generating device, the activity is further simplified.
- the thread bundle generating device generates a number of bundles of filaments from the incoming bundle of threads, wherein the number of bundles of filaments expediently corresponds to the number of available knotting devices. Since the fiber bundle generating device is at least partially movable relative to the yarn sheet path, it can dive into the yarn sheet path and there bundle the yarns into bundles of filaments.
- the thread bundle generating device has a carrier, on which a plurality of protrusions projecting from the carrier in the direction of the yarn bundle are arranged, wherein each protuberance is assigned a gripper.
- the projections can then enter the group of threads and subdivide the group of threads in the width direction into as many sections as node directions are present. These sections are then pushed together by the gripper so that a bundle of threads is formed.
- the projections have a tip and are movable into the yarn sheet.
- the tip facilitates the introduction of the projections in the yarn sheet. The risk that the threads of the yarn sheet are damaged, is relatively low.
- a second filament-forming device is arranged in a direction from the warp beam storage to the knotting device behind the knotting device.
- the second thread bundle generating device may be configured in the same way as the first thread bundle generating device described above. With the second filament bundle generating device, a corresponding number of filament bundles can be generated from the outgoing filament bundle which are then arranged in the first path of the web.
- each gap between a projection and a gripper is associated with a knotting device. This ensures in a simple manner a match between the number of Knot drivenen and the number of resulting filament bundles.
- the gripper and a projection, which is adjacent to the gripper associated projection can be brought into overlap. This ensures that the gripper does not interfere with the separation of the threads into individual groups, from which the bundles of fibers are later formed. He rather disappears in or behind the lead.
- the gripper and the projection are each formed from a plurality of layers, wherein intermediate spaces are formed between the layers and the layers of the gripper enter into intermediate spaces of the projection.
- Fig. 9 It is first referred to the highly schematic representation of a gate 1, as in Fig. 9 is shown.
- the gate 1 has two Kettbaumlagerened 2, 3, wherein in each Kettbaumlagerung 2, 3 a partial warp beam 4, 5 is arranged. From each partial warp beam 4, 5 a Partfadenschar 6, 7 is subtracted. The sub-thread coulters 6, 7 are guided over guide rollers 8, 9 and united behind the last guide roller 9 to a yarn sheet 10. This group of threads 10 is then fed in the direction of an arrow 11 to an assembling device (or other processing device). The assembling device can also be preceded by a device for introducing a size.
- Kettbaumlagerache 2, 3 may be provided so that more than two Operakettbäume 4, 5 can be included in the gate 1.
- a first filament bundle generating device 14 generates a number of filament bundles from the incoming filament bundle B. These filament bundles are then severed in front of the traction device 12, that is to say between the traction device 12 and the knotter device 13, and, as described below, fed to the knotter device 13.
- a second filament bundling device 15 For the expiring yarn sheet A, a second filament bundling device 15 is provided.
- the second thread bundle generating device 15 also generates a number of bundles of filaments, wherein the number of bundles of threads of the expiring thread sheet A and the number of thread bundles of the tapering thread group B are equal. Expediently, the running thread group A and the tapering thread group B still overlap.
- the filament bundles of the expiring yarn sheet A are referred to as the "first filament bundle” and the filament bundles of the incoming filament bundle B as "second filament bundle".
- the suction opening may be formed by a V-shaped notch 19 in the end face of the mandrel 17, wherein the base of the "V" is aligned parallel to the first filament bundle 16.
- the first thread bundle 16 extends in the direction of gravity, ie vertically. Accordingly, the base of the V-shaped notch 19 is also aligned in the direction of gravity.
- the suction opening 18 communicates with a suction device 20 in connection, so that the suction opening can be acted upon by a negative pressure.
- a suction device 20 By this vacuum, the first thread bundle, as shown in Fig. 2 is shown sucked into the mandrel 17.
- the first bundle of fibers 16 lies in a first web path, which in Fig. 1 is shown.
- This track path extends in front of the suction opening 18.
- the circumference of the spike forms a second track path 21.
- the second thread bundle 22 is now arranged in the second track path 21, that is placed around the circumference of the mandrel 17 to form a loop. This is for the sake of clarity in the Fig. 1 and 2 Not shown.
- the second bundle of filaments 22 is handled as follows: one end 23 of the second filament bundle 22 is deflected by 180 ° and, as it were, guided parallel to the incoming second filament bundle 22. Thus, a portion 24 of the filament bundle 22 and the end 23 of the second filament bundle 22 is parallel to each other and forms a kind of "U", which opens downwards. A base 25 of the U is then returned via the end 23 and the portion 24, so that a loop 26 is formed on the mandrel 17th can be deferred. This is a relatively easy operation. As stated above, first the second bundle of fibers 22 is guided through the second web path 21 and then the first bundle of fibers 16 is guided in the first web path.
- the mandrel 17 can be moved relative to the second bundle of filaments 22.
- a stripping device 27 is provided, so that the loop 26 can be stripped off the mandrel 17. The first bundle of fibers 16 then passes through the loop 26.
- the mandrel can then be moved farther away from the first web path and thus from the first bundle of fibers 16, so that the first bundle of fibers 16 is completely released from the mandrel 17.
- the second bundle of fibers 22 is guided with its portion 24 and its end 23 by a slider 28 which is displaceable parallel to the second bundle of filaments 22.
- the slider has two pins 29, 30. When the slider 28 is moved up to the second bundle of filaments 22, then push the two pins 29, 30, the base 25 of the U, ie a portion of the loop 26, over the loop 26 away, so that a in Fig. 5 illustrated cross-knot 31 results, which reliably connects the first bundle of threads 16 and the second bundle of threads 22 together.
- a holding rod is arranged approximately parallel to the mandrel 17, which has two portions extending parallel to the mandrel, which are connected by an angled portion.
- a Knotvorgangs is a parallel section next to the thorn.
- the second track path extends around the outside of the support rod, that the support rod is wrapped by the second thread bundle 22, ie, the base 25 of the U is located on the outside of the support rod and the two of the base 25 adjacent portion are arranged on both sides of the support rod, that is, a portion between the mandrel 17 and a portion outside.
- the mandrel 17 is then withdrawn together with the support rod so that the base 25 hinsteigerert the angled portion and passes to the other parallel portion of the support rod. Thereafter, at least the support rod is moved in the direction from which the first bundle of fibers 16 comes, so that the base 25 of the U is pulled in the direction of the first bundle of fibers 16 and thus forms a cross knot.
- filament-generating means 14, 15 are provided.
- the first thread bundle generating device 14 is based on Fig. 6 to 8 explained in more detail.
- the second filament-generating means 15 is constructed in the same way.
- the filament-generating device 14 has a carrier 32 which extends transversely to the yarn sheet 10 and is oriented substantially horizontally.
- the yarn sheet 10 is arranged in a yarn sheet path.
- the projections 33 are approximately triangular in plan view and have a tip 34, the tip 34 is directed to the yarn sheet 10 out. Furthermore, the projections 33 have a recess 35.
- Each projection 33 is associated with a gripper 36 which is displaceable parallel to the longitudinal extent of the carrier 32.
- a drive 37 is provided to move the gripper 36.
- each projection 33 is constructed of several layers 38, wherein intermediate spaces 39 are provided between the layers.
- the gripper 36 has a plurality of layers 40, between which intermediate spaces 41 are arranged.
- the layers 40 of the gripper 36 may enter the spaces 39 of the protrusion 33 and the layers 38 of the protrusion 33 may enter the spaces 41 of the gripper. This makes it possible to bring the projections and the grippers into coincidence with each other, as in Fig. 8 is shown.
- the carrier 32 is movable in the direction of an arrow 42 on the yarn sheet 10 in such a way that the projections 33 enter the yarn sheet 10 and form there several groups 43 of threads. Then, when the grippers 36 are moved, the threads of a group 43 are combined into a bundle and received in the recess 35.
- the filament bundles thus formed can be severed individually and in connection with Fig. 1 to 5 described procedure are placed around the mandrel 17 around.

Description
Die Erfindung betrifft eine Knoteinrichtung für ein Fadenbündel nach dem Oberbegriff des Anspruchs 1.The invention relates to a knotting device for a thread bundle according to the preamble of claim 1.
Ferner betrifft die Erfindung ein Gatter mit mindestens einer Kettbaumlagerung und einem Gatterausgang, an dem eine derartige Knoteinrichtung angeordnet ist.Furthermore, the invention relates to a gate with at least one warp beam storage and a gate exit, on which such a knotting device is arranged.
Die Erfindung wird im Folgenden anhand einer Assembliervorrichtung beschrieben, ohne jedoch darauf beschränkt zu sein.The invention will be described below with reference to an assembly device, but without being limited thereto.
Bei einer Assembliereinrichtung werden Fadenscharen, die von mehreren Teilkettbäumen abgezogen werden, zu einem Kettbaum vereinigt. Falls erforderlich, können die Fadenscharen oder die vereinigte Fadenschar, die auf den Kettbaum aufgewickelt wird, noch einer weiteren Behandlung unterworfen werden, beispielsweise kann eine Schlichte aufgetragen werden. Wenn die zugeführten Fadenscharen gewechselt werden müssen, beispielsweise weil ein oder mehrere Teilkettbäume leer gelaufen sind oder weil ein Kettbaum mit anderen Fäden erzeugt werden soll, ist es üblich, das Ende der aufgewickelten Fadenscharen mit dem Anfang der neu zugeführten Fadenscharen zu verbinden, so dass die neu zugeführten Fadenscharen auf dem gleichen Weg durch die Vorrichtung geführt werden können, wie die bisher aufgewickelten Fadenscharen.In an assembler yarn bundles, which are subtracted from several Teilkettbäumen, combined into a warp beam. If necessary, the yarn bundles or the combined yarn sheet, the is wound on the warp beam, are subjected to a further treatment, for example, a sizing can be applied. If the supplied yarn sheets must be changed, for example, because one or more warp beams have run empty or because a warp beam to be produced with other threads, it is common to connect the end of the wound yarn sheets with the beginning of the newly fed yarn sheets, so that the newly fed yarn sheets can be performed in the same way through the device, as the previously wound yarn sheets.
Hierzu geht man üblicherweise so vor, dass man aus dem Ende der auf den Kettbaum aufgewickelten Fadenschar mehrere erste Fadenbündel bildet und aus dem Anfang der neu zugeführten Fadenschar mehrere zweite Fadenbündel bildet. Jedes erste Fadenbündel wird dann mit einem zweiten Fadenbündel verknotet. Allerdings ist das Verknoten für eine Bedienungsperson relativ mühsam und anstrengend.For this purpose, one usually proceeds by forming a plurality of first bundles of filaments from the end of the bundle of threads wound on the warp beam and forming a plurality of second bundles of filaments from the beginning of the newly introduced bundle of threads. Each first bundle of fibers is then knotted with a second bundle of filaments. However, knotting for an operator is relatively tedious and exhausting.
Der Erfindung liegt die Aufgabe zugrunde, für eine Bedienungsperson die Arbeit am Ausgang eines Gatters zu vereinfachen.The invention has for its object to simplify the work for an operator at the output of a gate.
Diese Aufgabe wird bei einer Knoteinrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved in a knotting device with the features of claim 1.
Bei einer derartigen Knoteinrichtung ist es lediglich erforderlich, die beiden Fadenbündel entsprechend den Bahnpfaden anzuordnen. Beim ersten Bahnpfad ist dies relativ einfach, weil das Fadenbündel nur vor der Saugöffnung angeordnet werden muss. Wenn das erste Fadenbündel beispielsweise in Schwerkraftrichtung nach unten hängt, dann ist es in vielen Fällen automatisch richtig positioniert. Das zweite Fadenbündel muss lediglich um den Dorn herum gelegt werden und bildet dadurch eine Schlaufe oder dergleichen. Die Saugöffnung kann mit Hilfe der Saugeinrichtung besaugt werden. Wenn die Saugöffnung besaugt wird, also hier ein Unterdruck erzeugt wird, dann wird das erste Fadenbündel in die Saugöffnung hineingesaugt und tritt damit durch die Masche oder Schlaufe hindurch, die das zweite Fadenbündel im zweiten Bahnpfad bildet. Der Dorn, der relativ zum ersten Bahnpfad verlagerbar ist, kann dann verlagert werden, so dass das erste Fadenbündel mit der Masche oder Schlaufe des zweiten Fadenbündels in Eingriff steht. Die Schlaufe muss dann lediglich noch zugezogen werden, um die beiden Fadenbündel ausreichend fest miteinander zu verbinden.In such a knotting device, it is only necessary to arrange the two filament bundles according to the web paths. In the first path this is relatively easy, because the bundle of fibers must be arranged only in front of the suction opening. For example, if the first bundle of threads hangs down in the direction of gravity, then in many cases it is automatically positioned correctly. The second bundle of fibers merely has to be placed around the mandrel and thereby forms a loop or similar. The suction opening can be sucked by means of the suction device. If the suction opening is evacuated, so here a negative pressure is generated, then the first bundle of fibers is sucked into the suction opening and thus passes through the loop or loop, which forms the second bundle of filaments in the second path. The mandrel, which is displaceable relative to the first web path, can then be displaced so that the first bundle of filaments is engaged with the loop or loop of the second bundle of filaments. The loop then only has to be tightened in order to connect the two bundles of fibers sufficiently firmly together.
Der Dorn ist relativ zu einer Abstreifeinrichtung verlagerbar. Wenn der Dorn verlagert wird, dann kann die Abstreifeinrichtung das zweite Fadenbündel vom Dorn abstreifen, so dass die vom zweiten Fadenbündel gebildete Schlaufe über das erste Fadenbündel rutschen kann, so dass die beiden Fadenbündel zuverlässig miteinander in Eingriff stehen.The mandrel is displaceable relative to a stripping device. When the mandrel is displaced, the stripping means may strip the second bundle of filaments from the mandrel so that the loop formed by the second bundle of filaments may slip over the first bundle of filaments so that the two bundles of filaments are reliably engaged with each other.
Zum Dorn benachbart ist eine Überwurfeinrichtung angeordnet. Die Überwurfeinrichtung kann verwendet werden, die vom zweiten Fadenbündel gebildete Schlaufe über das erste Fadenbündel zu schieben und zwar in Richtung der Längserstreckung des ersten Fadenbündels im Bereich des sich bildenden Knotens, so dass sich ein Kreuzknoten ergibt.Adjacent to the mandrel, a throw-over device is arranged. The throw-over device can be used to push the loop formed by the second bundle of filaments over the first bundle of filaments, namely in the direction of the longitudinal extension of the first bundle of filaments in the region of the forming node, so that a cross-knot results.
Vorzugsweise verläuft der zweite Bahnpfad durch einen Schieber hindurch, der entlang eines Teils des zweiten Bahnpfades verlagerbar ist. Mit Hilfe eines derartigen Schiebers, der einen Teil der Überwurfeinrichtung bildet, kann der Knoten sozusagen festgezogen werden. In einer besonders bevorzugten Ausführungsform wird das Ende des zweiten Fadenbündels einmal umgeklappt, so dass es parallel zum Rest des zweiten Fadenbündels eine Strecke wieder zurückgeführt wird. Dieser doppelte Bündelverlauf wird dann einmal durch das U-förmige Ende des doppelten Bündelverlaufs gezogen und bildet somit eine Schlaufe. Diese Schlaufe wird im zweiten Bahnpfad angeordnet. Der Schieber kann dann, wenn die Schlaufe auf das erste Fadenbündel aufgeschoben worden ist, die Spitze des "U" über die Schlaufe hinweg schieben, so dass dadurch ein Kreuzknoten entsteht. Ein derartiger Kreuzknoten verbindet die beiden Fadenbündel mit ausreichender Festigkeit, so dass mit einem derartigen Knoten das zweite Fadenbündel mit Hilfe des ersten Fadenbündels durch eine nachfolgende Verarbeitungsmaschine gezogen werden kann.Preferably, the second track path passes through a slider that is displaceable along a portion of the second track path. With the help of such a slider, which forms part of the throw-over device, the node can be tightened, so to speak. In a particularly preferred embodiment, the end of the second bundle of filaments is folded over once, so that it is returned a distance parallel to the rest of the second bundle of filaments. This double bunching becomes then once pulled through the U-shaped end of the double bundle course and thus forms a loop. This loop is arranged in the second path. When the loop has been pushed onto the first bundle of threads, the slider can push the tip of the "U" over the loop, thereby creating a cross knot. Such a cross knot connects the two bundles of fibers with sufficient strength, so that with such a node, the second bundle of filaments can be pulled by a subsequent processing machine with the aid of the first bundle of filaments.
In einer weiteren Alternative kann die Überwurfeinrichtung auch eine Haltestange aufweisen, um die herum der zweite Bahnpfad verläuft und die relativ zum ersten Bahnpfad beweglich ist. Diese Haltestange wird verwendet, um die vom zweiten Fadenbündel gebildete Schlaufe festzuhalten, wenn das zweite Fadenbündel vom Dorn abgestreift wird. Die Haltestange kann dann in eine Richtung geführt werden, aus der das erste Fadenbündel zuläuft und damit die vom zweiten Fadenbündel gebildete Schlaufe über das erste Fadenbündel schieben. Auch damit lässt sich zuverlässig ein Kreuzknoten erhalten.In a further alternative, the throw-over device can also have a holding bar, around which the second track path runs and which is movable relative to the first track path. This support bar is used to hold the loop formed by the second bundle of filaments when the second bundle of filaments is stripped off the mandrel. The support rod can then be guided in a direction from which the first bundle of threads tapers and thus push the loop formed by the second bundle of filaments over the first bundle of filaments. Even with this, a cross knot can be reliably obtained.
Die Erfindung betrifft auch ein Gatter mit einer derartigen Knoteinrichtung am Gatterausgang.The invention also relates to a gate with such a knotting device at the gate output.
Der Bediener muss bei einem derartigen Gatter lediglich die Fadenbündel der ablaufenden Fadenschar in die richtige Position vor den Saugöffnungen bringen und zuvor die Fadenbündel aus der zulaufenden Fadenschar im zweiten Bahnpfad anordnen. Diese Tätigkeit ist relativ einfach und körperlich nicht anstrengend. Danach muss die Knoteinrichtung lediglich in Funktion gesetzt werden, indem die Saugeinrichtung saugt und dann, wenn das erste Fadenbündel jeweils in die Saugöffnung eingetreten ist, der Dorn relativ zum ersten Bahnpfad bewegt wird. Es bilden sich dann bei allen Paarungen aus erstem und zweitem Fadenbündel die entsprechenden Knoten. Dieser Vorgang geht auch relativ schnell, so dass für den Wechsel nicht allzu viel Zeit verschwendet wird.The operator must bring in such a gate, only the yarn bundles of the expiring yarn sheet in the correct position in front of the suction and previously arrange the filament bundles from the incoming yarn sheet in the second path. This activity is relatively simple and physically not exhausting. Thereafter, the knotter need only be set in operation by the suction sucks and then, when the first bundle of filaments has entered each of the suction opening, the mandrel is moved relative to the first path. It then forms on all pairings first and second thread bundle the corresponding nodes. This process is also relatively fast, so that not too much time is wasted for the change.
Vorzugsweise ist zwischen der Kettbaumlagerung und der Knoteinrichtung ein Fadenscharpfad angeordnet und eine Fadenbündelerzeugungseinrichtung ist vorgesehen, die zumindest teilweise relativ zum Fadenscharpfad bewegbar ist. Mit der Fadenbündelerzeugungseinrichtung wird die Tätigkeit weiter vereinfacht. Die Fadenbündelerzeugungseinrichtung erzeugt aus der zulaufenden Fadenschar eine Anzahl von Fadenbündeln, wobei die Anzahl der Fadenbündel zweckmäßigerweise der Anzahl der zur Verfügung stehenden Knoteinrichtungen entspricht. Da die Fadenbündelerzeugungseinrichtung zumindest teilweise relativ zum Fadenscharpfad bewegbar ist, kann sie in den Fadenscharpfad eintauchen und dort die Fäden bündelweise zu Fadenbündeln zusammenfassen.Preferably, a yarn sheet path is arranged between the warp beam storage and the knotting device and a fiber bundle generating device is provided, which is at least partially movable relative to the yarn sheet path. With the thread bundle generating device, the activity is further simplified. The thread bundle generating device generates a number of bundles of filaments from the incoming bundle of threads, wherein the number of bundles of filaments expediently corresponds to the number of available knotting devices. Since the fiber bundle generating device is at least partially movable relative to the yarn sheet path, it can dive into the yarn sheet path and there bundle the yarns into bundles of filaments.
Hierbei ist bevorzugt, dass die Fadenbündelerzeugungseinrichtung einen Träger aufweist, an dem mehrere vom Träger in Richtung auf die Fadenschar vorstehende Vorsprünge angeordnet sind, wobei jedem Vorsprung ein Greifer zugeordnet ist. Die Vorsprünge können dann in die Fadenschar eintreten und die Fadenschar in Breitenrichtung in so viele Abschnitte unterteilen, wie Knotenrichtungen vorhanden sind. Diese Abschnitte werden dann durch den Greifer zusammengeschoben, so dass ein Fadenbündel entsteht.In this case, it is preferred that the thread bundle generating device has a carrier, on which a plurality of protrusions projecting from the carrier in the direction of the yarn bundle are arranged, wherein each protuberance is assigned a gripper. The projections can then enter the group of threads and subdivide the group of threads in the width direction into as many sections as node directions are present. These sections are then pushed together by the gripper so that a bundle of threads is formed.
Hierbei ist bevorzugt, dass die Vorsprünge eine Spitze aufweisen und in die Fadenschar hinein bewegbar sind. Die Spitze erleichtert das Einbringen der Vorsprünge in die Fadenschar. Die Gefahr, dass die Fäden der Fadenschar beschädigt werden, ist relativ gering.It is preferred that the projections have a tip and are movable into the yarn sheet. The tip facilitates the introduction of the projections in the yarn sheet. The risk that the threads of the yarn sheet are damaged, is relatively low.
Vorzugsweise ist in eine Richtung von der Kettbaumlagerung zur Knoteinrichtung hinter der Knoteinrichtung eine zweite Fadenbündelerzeugungseinrichtung angeordnet. Die zweite Fadenbündelerzeugungseinrichtung kann genauso ausgebildet sein, wie die zuvor beschriebene erste Fadenbündelerzeugungseinrichtung. Mit der zweiten Fadenbündelerzeugungseinrichtung lässt sich aus der ablaufenden Fadenschar eine entsprechende Anzahl von Fadenbündeln erzeugen, die dann im ersten Bahnpfad angeordnet sind.Preferably, a second filament-forming device is arranged in a direction from the warp beam storage to the knotting device behind the knotting device. The second thread bundle generating device may be configured in the same way as the first thread bundle generating device described above. With the second filament bundle generating device, a corresponding number of filament bundles can be generated from the outgoing filament bundle which are then arranged in the first path of the web.
Vorzugsweise ist jedem Zwischenraum zwischen einem Vorsprung und einem Greifer eine Knoteinrichtung zugeordnet. Damit wird auf einfache Weise eine Übereinstimmung zwischen der Anzahl der Knoteinrichtungen und der Anzahl der entstehenden Fadenbündel gewährleistet.Preferably, each gap between a projection and a gripper is associated with a knotting device. This ensures in a simple manner a match between the number of Knoteinrichtungen and the number of resulting filament bundles.
Vorzugsweise sind der Greifer und ein Vorsprung, der dem dem Greifer zugeordneten Vorsprung benachbart ist, in Überdeckung bringbar. Damit ist sichergestellt, dass der Greifer beim Separieren der Fäden zu einzelnen Gruppen, aus denen später die Fadenbündel gebildet werden, nicht stört. Er verschwindet vielmehr im oder hinter dem Vorsprung.Preferably, the gripper and a projection, which is adjacent to the gripper associated projection, can be brought into overlap. This ensures that the gripper does not interfere with the separation of the threads into individual groups, from which the bundles of fibers are later formed. He rather disappears in or behind the lead.
Hierbei ist bevorzugt, dass der Greifer und der Vorsprung jeweils aus mehreren Schichten gebildet sind, wobei zwischen den Schichten Zwischenräume ausgebildet sind und die Schichten des Greifers in Zwischenräume des Vorsprungs eintreten.In this case, it is preferred that the gripper and the projection are each formed from a plurality of layers, wherein intermediate spaces are formed between the layers and the layers of the gripper enter into intermediate spaces of the projection.

Es wird zunächst auf die stark schematisierte Darstellung eines Gatters 1 verwiesen, wie es in
Das Gatter 1 weist zwei Kettbaumlagerungen 2, 3 auf, wobei in jeder Kettbaumlagerung 2, 3 ein Teilkettbaum 4, 5 angeordnet ist. Von jedem Teilkettbaum 4, 5 wird eine Teilfadenschar 6, 7 abgezogen. Die Teilfadenscharen 6, 7 werden über Umlenkrollen 8, 9 geleitet und hinter der letzten Umlenkrolle 9 zu einer Fadenschar 10 vereinigt. Diese Fadenschar 10 wird dann in Richtung eines Pfeils 11 einer Assembliervorrichtung (oder einer anderen Verarbeitungseinrichtung) zugeführt. Der Assembliervorrichtung kann noch eine Vorrichtung zum Eintragen einer Schlichte vorgeschaltet sein.The gate 1 has two
Natürlich können auch mehr als die beiden dargestellten Kettbaumlagerungen 2, 3 vorgesehen sein, so dass auch mehr als zwei Teilkettbäume 4, 5 im Gatter 1 aufgenommen werden können.Of course, more than the two shown
Wenn ein Wechsel der Teilkettbäume 4, 5 erforderlich ist, weil beispielsweise die Teilkettbäume 4, 5 leer gelaufen sind oder eine andere Fadenschar 10 weiterbehandelt werden soll, geht man wie folgt vor, wobei zur leichteren Unterscheidung die alte Fadenschar, also die ablaufende Fadenschar, mit "A" und die neue Fadenschar, also die zulaufende Fadenschar, mit "B" bezeichnet wird.If a change of the
Die zulaufende Fadenschar B wird von den (neuen) Teilkettbäumen 4, 5 abgezogen und bis hinter eine Knoteinrichtung 13 gezogen, die in
Für die ablaufende Fadenschar A ist eine zweite Fadenbündelerzeugungseinrichtung 15 vorgesehen. Die zweite Fadenbündelerzeugungseinrichtung 15 erzeugt ebenfalls eine Anzahl von Fadenbündeln, wobei die Anzahl der Fadenbündel der ablaufenden Fadenschar A und die Anzahl der Fadenbündel der zulaufenden Fadenschar B gleich groß sind. Zweckmäßigerweise überlappen sich dabei die ablaufende Fadenschar A und die zulaufende Fadenschar B noch. Um die nachfolgende Beschreibung zu vereinfachen, werden die Fadenbündel der ablaufenden Fadenschar A als "erste Fadenbündel" und die Fadenbündel der zulaufenden Fadenschar B als "zweite Fadenbündel" bezeichnet.For the expiring yarn sheet A, a second
Wie in den
Die Saugöffnung 18 steht mit einer Saugeinrichtung 20 in Verbindung, so dass die Saugöffnung mit einem Unterdruck beaufschlagt werden kann. Durch diesen Unterdruck wird das erste Fadenbündel, wie dies in
Das erste Fadenbündel 16 liegt in einem ersten Bahnpfad, der in
In einer besonders vorteilhaften Ausgestaltung wird hierzu das zweite Fadenbündel 22 wie folgt gehandhabt: ein Ende 23 des zweiten Fadenbündels 22 wird um 180° umgelenkt und sozusagen parallel mit dem zulaufenden zweiten Fadenbündel 22 geführt. Damit liegt ein Abschnitt 24 des Fadenbündels 22 und das Ende 23 des zweiten Fadenbündels 22 parallel zueinander und bildet eine Art "U", das sich nach unten öffnet. Eine Basis 25 des U wird dann über das Ende 23 und den Abschnitt 24 zurückgeführt, so dass sich eine Schlaufe 26 bildet, die auf den Dorn 17 aufgeschoben werden kann. Dies ist eine relativ einfache Handhabung. Wie oben ausgeführt, wird zunächst das zweite Fadenbündel 22 durch den zweiten Bahnpfad 21 geführt und dann das erste Fadenbündel 16 in den ersten Bahnpfad geführt. Sobald das erste Fadenbündel 16 in den Dorn hineingesaugt worden ist, kann der Dorn 17 relativ zum zweiten Fadenbündel 22 bewegt werden. Zweckmäßigerweise ist eine Abstreifeinrichtung 27 vorgesehen, so dass die Schlaufe 26 vom Dorn 17 abgestreift werden kann. Das erste Fadenbündel 16 verläuft dann durch die Schlaufe 26 hindurch.In a particularly advantageous embodiment, the second bundle of
Der Dorn kann dann weiter weg bewegt werden vom ersten Bahnpfad und damit vom ersten Fadenbündel 16, so dass das erste Fadenbündel 16 vollständig vom Dorn 17 frei kommt.The mandrel can then be moved farther away from the first web path and thus from the first bundle of
Das zweite Fadenbündel 22 ist mit seinem Abschnitt 24 und seinem Ende 23 durch einen Schieber 28 hindurch geführt, der parallel zum zweiten Fadenbündel 22 verlagerbar ist. Der Schieber weist zwei Stifte 29, 30 auf. Wenn der Schieber 28 auf das zweite Fadenbündel 22 hinauf bewegt wird, dann schieben die beiden Stifte 29, 30 die Basis 25 des U, also einen Teil der Schlaufe 26, über die Schlaufe 26 hinweg, so dass sich ein in
Anstelle einer Überwurfeinrichtung, die den Schieber 28 aufweist, kann in nicht näher dargestellter Weise auch eine andere Ausbildung einer Überwurfeinrichtung verwendet werden. Hierzu ist etwa parallel zum Dorn 17 eine Haltestange angeordnet, die zwei parallel zum Dorn verlaufende Abschnitte aufweist, die durch einen abgewinkelten Abschnitt verbunden sind. Zu Beginn eines Knotvorgangs befindet sich ein paralleler Abschnitt neben dem Dorn. Der zweite Bahnpfad verläuft außen so um die Haltestange herum, dass die Haltestange vom zweiten Fadenbündel 22 umschlungen wird, d.h. die Basis 25 des U befindet sich außen an der Haltestange und die zwei der Basis 25 benachbarten Abschnitt sind auf beiden Seiten der Haltestange angeordnet, also ein Abschnitt zwischen dem Dorn 17 und ein Abschnitt außerhalb.Instead of a throw-over device which has the
Der Dorn 17 wird dann gemeinsam mit der Haltestange zurückgezogen, so dass die Basis 25 den abgewinkelten Abschnitt hinaufwandert und zum anderen parallelen Abschnitt der Haltestange gelangt. Danach wird zumindest die Haltestange in die Richtung bewegt, aus der das erste Fadenbündel 16 kommt, so dass die Basis 25 des U in Richtung auf das erste Fadenbündel 16 gezogen wird und sich somit ein Kreuzknoten bildet.The
Um die Fadenbündel zu erzeugen, sind, wie dies oben bereits erläutert worden ist, Fadenbündelerzeugungseinrichtungen 14, 15 vorgesehen. Die erste Fadenbündelerzeugungseinrichtung 14 wird anhand von
Die Fadenbündelerzeugungseinrichtung 14 weist einen Träger 32 auf, der sich quer zur Fadenschar 10 erstreckt und im Wesentlichen horizontal ausgerichtet ist. Die Fadenschar 10 ist in einem Fadenscharpfad angeordnet.The filament-generating
Am Träger 32 ist eine größere Anzahl von Vorsprüngen 33 angeordnet. Die Vorsprünge 33 sind in der Draufsicht etwa dreieckförmig ausgebildet und weisen eine Spitze 34 auf, wobei die Spitze 34 zur Fadenschar 10 hin gerichtet ist. Ferner weisen die Vorsprünge 33 eine Ausnehmung 35 auf.On the
Jedem Vorsprung 33 ist ein Greifer 36 zugeordnet, der parallel zur Längserstreckung des Trägers 32 verlagerbar ist. Zur Bewegung der Greifer 36 ist ein Antrieb 37 vorgesehen.Each
Wie man insbesondere in
Auch der Greifer 36 weist mehrere Schichten 40 auf, zwischen denen Zwischenräume 41 angeordnet sind. Die Schichten 40 des Greifers 36 können in die Zwischenräume 39 des Vorsprungs 33 eintreten und die Schichten 38 des Vorsprungs 33 können in die Zwischenräume 41 des Greifers eintreten. Damit ist es möglich, die Vorsprünge und die Greifer miteinander in Überdeckung zu bringen, wie dies in
