Description

Die Erfindung betrifft eine Musterkettenschärmaschine mit einer Schärtrommel, mindestens einem um den Umfang der Schärtrommel bewegbaren Fadenführer und einem Drehgatter mit mehreren Spulenaufsteckungen, wobei dem Drehgatter benachbart eine Bestückungseinrichtung angeordnet ist, die eine Handhabe aufweist, die bis zu mindestens einer Spulenaufsteckung bewegbar ist.The invention relates to a sample warping machine with a warping drum, at least one thread guide movable about the circumference of the warping drum and a rotary gate with a plurality of Spulenaufsteckungen, wherein the rotary gate adjacent a loading device is arranged, which has a handle which is movable up to at least one Spulenaufsteckung.

Eine derartige Musterkettenschärmaschine ist beispielsweise aus EP 1 136 602 A1 bekannt. Dort ist eine Musterkettenschärmaschine offenbart, die eine Schärtrommel mit bewegbaren Fadenführern und ein Drehgatter mit mehreren Spulenhalterungen aufweist. Neben dem Drehgatter ist ein Spulenmagazin angeordnet, wobei mit Hilfe einer nicht näher dargestellten Bestückungseinrichtung, die eine Roboterhand aufweisen kann, Spulen vom Spulenmagazin in das Drehgatter überführt werden können.Such a sample warper is for example out EP 1 136 602 A1 known. There is disclosed a pattern warping machine comprising a warping drum with movable yarn guides and a rotary creel having a plurality of bobbin supports. In addition to the rotary gate, a reel magazine is arranged, with the aid of an insertion device, not shown, which may have a robot hand, coils can be transferred from the reel magazine into the rotary creel.

Eine Musterkettenschärmaschine dient dazu, eine Musterkette oder eine kurze Produktionskette herzustellen. Zur Herstellung steht die Schärtrommel in der Regel still. Der oder die Fadenführer rotieren dabei um den Umfang der Schärtrommel und legen dabei Fäden auf Transportbändern ab, die sich von den Fadenführern weg bewegen. Die Fäden werden dabei von Spulen abgezogen, die in den Spulenaufsteckungen am Drehgatter angeordnet sind.A pattern warper serves to produce a pattern string or a short production chain. For production, the warping drum is usually quiet. The one or more yarn guides rotate around the circumference of the warping drum and thereby lay threads on conveyor belts, which move away from the yarn guides. The threads are deducted from coils which are arranged in the Spulenaufsteckungen on the rotary gate.

Mit einem Drehgatter ist es möglich, mehrere Fäden gleichzeitig für die Produktion der Kette zu verwenden. Da die Anzahl der Spulenaufsteckungen auf dem Drehgatter aber begrenzt ist, sind die Gestaltungsmöglichkeiten bei der Kette begrenzt. Man kann lediglich so viele unterschiedliche Fäden verwenden, wie Spulenaufsteckungen im Drehgatter zur Verfügung stehen. Wenn man eine größere Musterungsvielfalt erreichen möchte, muss im Verlaufe der Herstellung der Kette die Musterkettenschärmaschine still gesetzt und eine Spule ausgetauscht werden, um den gewünschten Faden mit in die Kette einbauen zu können. Dies setzt die Produktivität herab. Ähnliche Probleme ergeben sich dann, wenn die auf einer Spule vorhandene Fadenmenge für die Länge dieses Fadens in der Kette nicht ausreicht. Auch in diesem Fall ergeben sich Unterbrechungen der Produktion, was zu einer geringen Produktivität führt.With a rotary gate, it is possible to use several threads simultaneously for the production of the chain. However, since the number of Spulenaufsteckungen on the rotary gate is limited, the design options in the chain are limited. You can only have so many use different threads, such as Spulenaufsteckungen in the rotary gate are available. If you want to achieve a greater variety of patterning, the sample warping machine must be set in the course of the production of the chain and a spool to be replaced in order to install the desired thread in the chain can. This lowers productivity. Similar problems arise when the amount of thread present on a bobbin is insufficient for the length of this thread in the chain. Also in this case, there are interruptions of production, resulting in low productivity.

Der Erfindung liegt die Aufgabe zugrunde, eine Musterkettenschärmaschine mit einer hohen Produktivität bereitzustellen.The invention has for its object to provide a pattern warping machine with a high productivity.

Diese Aufgabe wird bei einer Musterkettenschärmaschine der eingangs genannten Art dadurch gelöst, dass die Handhabe zwei Spulenhalter aufweist.This object is achieved in a sample warping machine of the type mentioned above in that the handle has two coil holder.

Mit der Bestückungseinrichtung, mit anderen Worten einem Bestückungsroboter, ist es nun möglich, die Zeiten, die zum Wechseln einer Spule notwendig sind, ganz erheblich zu vermindern. Die Bestückungseinrichtung kann nämlich unmittelbar nach dem Stopp der Musterkettenschärmaschine in Betrieb genommen werden, ohne dass man warten muss, bis eine Bedienungsperson die Musterkettenschärmaschine erreicht und den Spulenwechsel vornimmt. Die im Drehgatter angeordneten Spulen haben teilweise eine erhebliche Masse von in der Regel weit über 10 kg. Durch die Verwendung einer Bestückungseinrichtung entlastet man die Bedienungsperson. Dementsprechend ist das Risiko von Fehlern vermindert. Bei jedem Fehler müsste die Musterkettenschärmaschine erneut gestoppt werden. Wenn man Fehler vermeidet, werden die Stillstandszeiten vermindert und dadurch die Produktivität erhöht. Da die Handhabe zwei Spulenhalter aufweist, kann man eine Handhabe dafür verwenden, eine leere oder nicht mehr benötigte Spule aus dem Drehgatter zu entnehmen, und die andere Handhabe, um die volle oder neue Spule in die Spulenaufsteckung des Drehgatters einzusetzen. Dies hält Handhabungszeiten kurz, weil die Handhabe im Grunde pro Spulenwechsel nur einmal in Richtung auf die Wechselposition verfahren werden muss.With the placement device, in other words a placement robot, it is now possible to significantly reduce the times that are necessary to change a coil. Namely, the loading device can be put into operation immediately after the stop of the pattern warping machine without having to wait for an operator to reach the pattern warping machine and make the bobbin change. The arranged in the rotary creel some have a considerable mass of usually far over 10 kg. By using a loading device relieves the operator. Accordingly, the risk of errors is reduced. For every error, the sample warping machine would have to be stopped again. Avoiding mistakes reduces downtime and increases productivity. Since the handle has two spool holders, one can use a handle to remove an empty or unneeded spool from the spool, and the other handle to insert the full or new spool into the spool slot of the spool. This keeps handling times short because the handle basically only has to be moved once per bobbin change in the direction of the change position.

Vorzugsweise sind das Drehgatter und die Bestückungseinrichtung mit einer gemeinsamen Steuereinrichtung verbunden, wobei die Steuereinrichtung das Drehgatter zu einem Spulenwechsel in Abhängigkeit von einer neu zu bestückenden Spulenaufsteckung positioniert. Die Steuereinrichtung bekommt also eine Information darüber, welche Spulenaufsteckung mit einer neuen oder anderen Spule versorgt werden muss und steuert in Abhängigkeit von dieser Information die Bestückungseinrichtung. Die Information darüber, welche Spulenaufsteckung neu oder anders bestückt werden muss, gewinnt die Steuereinrichtung aus dem Programm, das die zu erfolgende Kette definiert. Dementsprechend ist für die Bedienung der Bestückungseinrichtung nur wenig zusätzliche Information notwendig, die von einem Bediener leicht in die Steuereinrichtung eingegeben werden kann.Preferably, the rotary gate and the loading device are connected to a common control device, wherein the control device positions the rotary gate to a bobbin change as a function of a re-stocking Spulenstecksteckung. The controller thus receives information about which Spulenaufsteckung must be supplied with a new or different coil and controls in dependence on this information, the placement device. The information about which bobbin insertion needs to be re-stocked or otherwise, wins the controller from the program that defines the chain to be made. Accordingly, little additional information is necessary for the operation of the loading device, which can be easily entered by an operator in the control device.

Hierbei ist bevorzugt, dass das Drehgatter eine für alle Spulenaufsteckungen einer Gruppe gemeinsame Wechselposition aufweist. Mit dieser Ausgestaltung lässt sich der Aufbau der Bestückungseinrichtung stark vereinfachen. Die Bestückungseinrichtung muss nur in der Lage sein, diese Wechselposition zu erreichen und die dort befindliche Spule zu entnehmen und die entsprechende Spulenaufsteckung mit einer anderen Spule zu versehen. Wenn eine andere Spulenaufsteckung für den Spulenwechsel ansteht, dann dreht die Steuereinrichtung das Drehgatter einfach so, dass diese Spulenaufsteckung sich in der Wechselposition befindet. Die Bestückungseinrichtung muss dann wiederum nur diese Wechselposition erreichen, um auch für die andere Spulenaufsteckung den Spulenwechsel vornehmen zu können.In this case, it is preferred that the rotary gate has a common change position for all the coil suspensions of a group. With this configuration, the structure of the loading device can be greatly simplified. The loading device must only be able to reach this change position and to remove the coil located there and to provide the corresponding Spulenaufsteckung with another coil. If there is another bobbin slip for bobbin change, then the controller simply rotates the rotary creel so that this bobbin slip is in the change position. In turn, the placement device only has to reach this change position in order to be able to carry out the bobbin change also for the other bobbin attachment.

Hierbei ist besonders bevorzugt, dass die Spulenhalter abwechselnd in dieselbe Position verlagerbar sind. Dies lässt sich beispielsweise dadurch realisieren, dass die beiden Spulenhalter an den Enden eines zweiarmigen Hebels angeordnet sind, der um eine in der Mitte angeordnete Achse verschwenkt werden kann. In diesem Fall ist nur eine Bewegung der Handhabe in die Wechselposition notwendig. Ein Spulenhalter kann dann die auszutauschende Spule in der Spulenaufsteckung ergreifen. Wenn die Handhabe dann gedreht wird, wird die eine Spule gegen die andere Spule ausgetauscht, ohne dass eine weitere Verlagerung der Handhabe erforderlich ist.It is particularly preferred that the bobbin holders are alternately displaceable in the same position. This can be realized, for example, in that the two coil holders are arranged at the ends of a two-armed lever, which can be pivoted about an axis arranged in the middle. In this case, only one movement of the handle in the change position is necessary. A bobbin holder can then grasp the coil to be replaced in the Spulenstecksteckung. When the handle is then rotated, one spool is replaced with the other spool, without the need for further dislocation of the handle.

Vorzugsweise weist die Bestückungseinrichtung einen ersten Antrieb, mit dem die Handhabe in eine erste Richtung parallel zu einer Rotationsachse des Drehgatters bewegbar ist, und einen zweiten Antrieb auf, mit dem die Handhabe senkrecht zur ersten Richtung bewegbar ist. Man kommt also mit zwei Antrieben aus, um die Handhabe in die gewünschte Position zum Wechseln der Spulen zu verlagern. Dies hält den Aufwand klein, den man für den Aufbau der Bestückungseinrichtung treiben muss. Auch die Steuerung wird relativ einfach, weil man lineare Bewegungen mit geringem Aufwand steuern kann.Preferably, the loading device has a first drive, with which the handle in a first direction parallel to a rotation axis of the rotary gate is movable, and a second drive, with which the handle is movable perpendicular to the first direction. So you come with two drives to move the handle in the desired position to change the coils. This keeps the effort small that you have to drive for the construction of the equipment. Also, the control is relatively simple, because you can control linear movements with little effort.

Vorzugsweise ist ein Spulenmagazin an einer der Schärtrommel abgewandten Stirnseite des Drehgatters angeordnet. Wenn das Spulenmagazin sozusagen in der Verlängerung der Drehachse des Drehgatters angeordnet ist, dann reicht es aus, die Handhabe der Bestückungseinrichtung in diese Richtung zu verfahren, um eine neue Spule aus dem Spulenmagazin abholen bzw. eine alte oder gebrauchte Spule dort ablegen zu können. Auch diese Ausgestaltung vereinfacht den Aufbau der Bestückungseinrichtung.Preferably, a reel magazine is arranged on a side facing away from the warping drum of the rotary gate. If the reel magazine is arranged so to speak in the extension of the axis of rotation of the rotary gate, then it is sufficient to move the handle of the mounting device in this direction to pick up a new coil from the reel magazine or to put down an old or used coil there. This embodiment also simplifies the structure of the equipping device.

Hierbei ist bevorzugt, dass im Spulenmagazin Spulen mit der gleichen Achsausrichtung wie im Drehgatter angeordnet sind. Die Spulen können dann ohne Änderung ihrer Ausrichtung im Raum oder gegebenenfalls mit einer einfachen Drehung um 180° zwischen dem Spulenmagazin und dem Drehgatter transportiert werden. Auch dies hält den Steuerungsaufwand klein.It is preferred that in the reel magazine coils are arranged with the same axis alignment as in the rotary creel. The coils can then be transported without changing their orientation in space or optionally with a simple rotation through 180 ° between the reel magazine and the rotary gate. This also keeps the control effort small.

Vorzugsweise weist das Spulenmagazin eine Spulenfördereinrichtung auf. Die Spulenfördereinrichtung ist beispielsweise so vorgesehen, dass sie im Magazin befindliche Spulen in eine Richtung quer zur Rotationsachse des Drehgatters verlagern kann. In diesem Fall muss die Handhabe praktisch nur parallel zur Drehachse verfahrbar sein, um die Spulen aus dem Spulenmagazin entnehmen zu können. Wenn das Spulenmagazin mehrere übereinander angeordnete "Etagen" oder Spulengruppen aufweist, dann ist allenfalls noch eine Verlagerung der Handhabe in vertikaler Richtung erforderlich. Im Übrigen reicht aber die Bewegungsmöglichkeit der Handhabe senkrecht zur ersten Richtung aus, um sämtliche Spulen ergreifen zu können, die im Spulenmagazin angeordnet sind.The reel magazine preferably has a reel conveyor device. The bobbin conveying device is provided, for example, so that it can displace coils located in the magazine in a direction transverse to the axis of rotation of the rotary creel. In this case the handle must be practically movable only parallel to the axis of rotation to remove the coils from the reel magazine can. If the reel magazine has a plurality of "bumps" or groups of bobbins arranged one above the other, then at most a displacement of the handle in the vertical direction is required. Incidentally, however, the possibility of movement of the handle is sufficient perpendicular to the first direction to take all the coils can, which are arranged in the reel magazine.

Vorzugsweise weist die Bestückungseinrichtung einen Fadenknoter auf. Die Bestückungseinrichtung ist also nicht nur in der Lage, einen Spulenwechsel durch Austausch der Spulen vorzunehmen, sondern sie ist auch in der Lage, den auf der neuen Spule befindlichen Faden an den von der alten Spule abgetrennten Faden anzuknoten. Den Fadenknoter kann man auch verwenden, um bei einem Fadenbruch einzugreifen.The placement device preferably has a threadknot. The loading device is therefore not only able to make a bobbin change by replacing the coil, but it is also able to knot the thread located on the new coil to the separated from the old bobbin thread. The threadknot can also be used to intervene in a yarn breakage.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigt die

einzige Figur:
eine schematische Draufsicht auf einen Ausschnitt einer Musterkettenschärma- schine.
The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Herein shows the
only figure
a schematic plan view of a section of a Musterkettenschärma- machine.

Eine Musterkettenschärmaschine 1 weist eine nur zum Teil dargestellte Schärtrommel 2 auf, die beim Erzeugen der Musterkette still steht. Vor einer Stirnseite der Schärtrommel 2 ist ein Drehgatter 3 angeordnet, in dem mehrere Spulen 4 in zwei Gruppen entlang einer Rotationsachse 5 des Drehgatters 3 hintereinander angeordnet sind. Ein Antrieb 6 dient dazu, das Drehgatter 3 im Betrieb um die Achse 5 zu drehen.A sample warping machine 1 has a warping drum 2 which is only partially shown and stands still when the pattern chain is produced. Before a front side of the warping drum 2, a rotary gate 3 is arranged, in which a plurality of coils 4 in two groups along an axis of rotation 5 of the rotary gate 3 are arranged one behind the other. A drive 6 serves to rotate the rotary gate 3 in operation about the axis 5.

Zwischen dem Drehgatter 3 und der Schärtrommel 2 sind Fadenführer 7 angeordnet, wobei jeder Spule 4 ein Fadenführer 7 zugeordnet ist. Die Fadenführer 7 sind drehfest mit dem Drehgatter 3 verbunden und rotieren synchron mit dem Drehgatter 3. Jeder Fadenführer 7 zieht einen Faden 8 von der entsprechenden Spule 4 ab und legt ihn bei der Rotation um die Achse 5 um den Umfang der Schärtrommel 2 ab. Mit nicht näher dargestellten, aber an sich bekannten Förderbändern werden die einzelnen Windungen der Fäden 8 dann vom Drehgatter 3 weg transportiert.Between the rotary gate 3 and the warping drum 2 yarn guide 7 are arranged, each coil 4 is associated with a yarn guide 7. The yarn guides 7 are rotatably connected to the rotary gate 3 and rotate synchronously with the rotary gate 3. Each yarn guide 7 pulls a thread 8 from the corresponding coil 4 and places it in the rotation about the axis 5 around the circumference of the warping drum 2 from. With not shown, but known conveyor belts, the individual turns of the threads 8 are then transported away from the rotary gate 3.

Eine Spule 4 kann nur eine begrenzte Länge eines Fadens 8 aufnehmen. Wenn während eines Schärauftrags, d. h. während der Produktion einer Kette, der auf einer Spule 4 aufgewickelte Fadenvorrat verbraucht ist, dann muss die leere Spule 4 gegen eine volle Spule 4 ersetzt werden. Ein derartiger Ersatz einer Spule 4 ist auch dann erforderlich, wenn die im Drehgatter vorgesehene Anzahl von Spulen nicht ausreicht, um die für ein Muster in der Kette benötigte Anzahl von Fäden zur Verfügung zu stellen.A coil 4 can only take a limited length of a thread 8. If during a damage order, i. H. during the production of a chain, which is consumed on a spool 4 wound yarn supply, then the empty spool 4 must be replaced by a full spool 4. Such replacement of a spool 4 is required even if the number of spools provided in the spool gate is insufficient to provide the number of spools required for a pattern in the sprocket.

Um diesen Austausch von Spulen 4 vornehmen zu können, ist eine Bestückungseinrichtung 9 vorgesehen. Die Bestückungseinrichtung 9 weist eine Handhabe 10 mit zwei Armen 11, 12 auf, die um eine Achse 13 in Richtung eines Pfeiles 24 verschwenkbar ist. An jedem Arm 11, 12 kann eine Spule 4a, 4b befestigt werden.In order to make this exchange of coils 4, a loading device 9 is provided. The loading device 9 has a handle 10 with two arms 11, 12, which is pivotable about an axis 13 in the direction of an arrow 24. On each arm 11, 12 a coil 4a, 4b can be attached.

Die Bestückungseinrichtung 9 weist eine erste Bahn 14 auf, auf der die Handhabe 10 parallel zur Achse 5 in eine erste Richtung verlagerbar ist. Ein für die Verlagerung notwendiger Antrieb ist vorhanden, aber aus Gründen der Übersicht nicht dargestellt. So kann die Handhabe beispielsweise aus der mit durchgezogenen Linien dargestellten Position in eine mit gestrichelten Linien dargestellte Position verfahren werden, in der sie sich neben dem Drehgatter 3 befindet.The loading device 9 has a first path 14, on which the handle 10 is displaceable parallel to the axis 5 in a first direction. A necessary for the displacement drive is available, but not shown for reasons of clarity. Thus, the handle can be moved, for example, from the position shown by solid lines in a position shown by dashed lines, in which it is located next to the rotary gate 3.

Die Handhabe 10 ist allerdings nicht direkt auf der ersten Bahn 14 angeordnet, sondern über eine zweite Bahn 15, die senkrecht zur Richtung der Fahrbahn 14 verlagerbar ist. Dadurch ist es möglich, die Handhabe 10 aus einem Bereich außerhalb des Drehgatters 3 in einen Bereich innerhalb des Drehgatters 3 zu verlagern, so dass die Spulen 4a, 4b zu einer Spulenaufnahme 16 innerhalb des Drehgatters 3 verlagert werden kann.However, the handle 10 is not arranged directly on the first web 14, but via a second web 15 which is displaceable perpendicular to the direction of the roadway 14. This makes it possible to displace the handle 10 from an area outside the rotary gate 3 into a region within the rotary gate 3, so that the coils 4a, 4b can be displaced to form a coil seat 16 within the rotary gate 3.

Zum Austausch einer Spule 4 wird das Drehgatter 3 zunächst so gedreht, dass sich die entsprechende Spulenaufsteckung, auf der die auszuwechselnde Spule 4 angeordnet ist, neben der Bestückungseinrichtung 9, genauer gesagt neben der ersten Bahn 14 befindet. Dies kann durch eine nicht näher dargestellte Steuereinrichtung eingestellt werden, die sowohl das Drehgatter 3 als auch die Bestückungseinrichtung 9 steuert. Die Handhabe 10 fährt dann auf der ersten Bahn 14 bis zu der entsprechenden Spulenaufsteckung und dann mit Hilfe der zweiten Bahn 15 so, dass der eine Arm 11 die auszutauschende Spule 4a ergreifen kann. Wenn er sie ergriffen hat, dann wird die Handhabe um die Achse 13 gedreht, so dass die volle Spule 4b in die Spulenaufsteckung 16 eingesetzt werden kann.To replace a coil 4, the rotary gate 3 is first rotated so that the corresponding Spulenaufsteckung on which the coil 4 to be replaced is arranged, next to the placement device 9, more precisely next to the first web 14 is located. This can be adjusted by a control device, not shown, which controls both the rotary gate 3 and the loading device 9. The handle 10 then moves on the first track 14 to the corresponding Spulenstecksteckung and then with the aid of the second path 15 so that the one arm 11 can seize the coil to be replaced 4a. If he has grabbed them, then the handle is rotated about the axis 13, so that the full bobbin 4b can be inserted into the bobbin attachment 16.

In Verlängerung der Achse 5, d. h. gegenüber der Stirnseite des Drehgatters 3, die der Schärtrommel 2 abgewandt ist, ist ein Spulenmagazin 17 angeordnet, in dem sich mehrere Spulen 4c befinden. Das Spulenmagazin 17 weist eine Spulenfördereinrichtung 18 auf, die eine Spule 4c aus dem Spulenmagazin 17 ergreift und in eine Position 4d verlagern kann, in der sie von der Handhabe 10 der Bestückungseinrichtung 9 ergriffen werden kann. In dieser Position 4d kann auch eine verbrauchte Spule abgelegt werden, die aus dem Spulengatter 3 entnommen worden ist.In extension of the axis 5, d. H. opposite the end face of the rotary gate 3, which faces away from the warping drum 2, a reel magazine 17 is arranged, in which a plurality of reels 4c are located. The bobbin magazine 17 has a bobbin conveying device 18, which grips a bobbin 4c from the bobbin magazine 17 and can displace it into a position 4d in which it can be gripped by the handle 10 of the mounting device 9. In this position 4 d, a spent coil can be stored, which has been removed from the creel 3.

Vor dem Austausch einer Spule fährt also die Handhabe 10 an das der Position 4d benachbarte Ende der ersten Bahn 14 und nimmt dort eine frische Spule auf. Danach kann der oben geschilderte Spulenwechsel erfolgen.Before the replacement of a coil so the handle 10 moves to the position 4d adjacent the end of the first web 14 and takes there a fresh coil. Thereafter, the above-described bobbin change can take place.

Die Bestückungseinrichtung 9 weist auch einen Fadenknoter 19 auf, mit dem der Faden 8 der in der Spulenaufsteckung 16 ausgetauschten Spule mit dem Anfang des Fadens einer neuen Spule verknotet werden kann. Der Fadenknoter 19 kann auch bei einem Fadenbruch oder dergleichen verwendet werden.The loading device 9 also has a thread card 19, with which the thread 8 of the exchanged in the Spulenaufsteckung 16 coil can be knotted with the beginning of the thread of a new coil. The threadknotter 19 can also be used in a yarn breakage or the like.
