Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Handhabung von Webgeschirrelementen wie zum Beispiel eine Einziehmaschine und ein Verfahren zur Handhabung von Webgeschirrelementen.The present invention relates to a device for handling woven harness elements, such as a drawing-in machine and a method for handling woven harness elements.

Unter einer Einziehmaschine wird eine Maschine zum Einziehen von Fäden oder Kettfäden in Webgeschirrelemente verstanden, die in verschiedene Funktionseinheiten unterteilt werden kann und entsprechende Vorrichtungen und Teilvorrichtungen aufweist. Dies sind zum Beispiel Vorrichtungen zum Bereitstellen von Litzen und Lamellen, in die Fäden eingezogen werden sollen. In diesen Vorrichtungen zum Bereitstellen sind die Webgeschirrelemente, wie generell zum Beispiel auch bei deren Vertrieb oder beim Weben üblich, auf schienenartigen Führungen aneinander angrenzend aufgehängt. Weiterhin ist "eingangsseitig" eine Vorrichtung zum Vorhalten eines Webblatts erforderlich. Als zentrale Vorrichtung weist eine Einziehmaschine eine Einziehvorrichtung auf, die Fäden zum Beispiel durch Webblatt, Litze, Lamelle und durch Bestandteile eines Fadenkreuzes führt. Die eingezogen Lamellen und Litzen müssen "abrüstseitig" aus der Nähe der Einziehvorrichtung abtransportiert werden, um einen Rückstau zu verhindern. In der Einziehvorrichtung werden Litzen und Lamellen vorwiegend schnell über kurze Wegstrecken transportiert, um eine hohe Taktzahl beim Einziehen zu erreichen. Nach erfolgten Einzug müssen die Webgeschirrelemente über vorwiegend lange schienenartige Führungen geschoben werden. Dieser Abtransport erfolgt in überwiegend langsamer Geschwindigkeit, allerdings sind verhältnismäßig große Wegstrecken für die Webgeschirrelemente zurückzulegen. Dies sind typischerweise 2 bis 3 m, teilweise sind aber auch bis zu 6 m erforderlich. Oft sind "abrüstseitig" Lamellen und Litzen parallel in nebeneinander angeordneten Vorrichtungen abzutransportieren. Die vorliegende Erfindung befasst sich schwerpunktmäßig mit dem Transport der Webgeschirrelemente von einer Bereitstellungsvorrichtung über die Einziehvorrichtung bis zu der Aufnahmevorrichtung. Vorteilhafterweise befasst sich die Erfindung mit einem Modul zum Litzentransport, jedoch sind Lamellen nicht ausgenommen.A drawing-in machine is understood to be a machine for drawing in threads or warp threads into woven harness elements, which can be divided into different functional units and has corresponding devices and sub-devices. These are, for example, devices for providing strands and slats into which threads are to be drawn. In these devices for providing, the weaving harness elements are suspended adjacent to one another on rail-like guides, as is generally the case in their distribution or weaving, for example. Furthermore, a device for holding a reed is required on the “input side”. As a central device, a drawing-in machine has a drawing-in device that guides threads, for example, through the reed, heddle, lamella and through components of a crosshair. The slats and strands that have been pulled in must be removed from the "removal side" near the pull-in device in order to prevent a backlog. In the pulling device, strands and slats are transported quickly over short distances in order to achieve a high number of cycles when pulling in. Once the weaving harness elements have been drawn in, they have to be pushed over predominantly long rail-like guides. This removal takes place at a predominantly slow speed, but relatively long distances have to be covered for the weaving harness elements. This is typically 2 to 3 m, but sometimes up to 6 m is required. Often, slats and strands have to be transported away in parallel in devices arranged next to one another on the “removal side”. The present invention is primarily concerned with the transport of the weaving harness elements from a supply device via the drawing-in device to the receiving device. The invention advantageously deals with a module for transporting strands, but slats are not excluded.

Die DE69008100T2 beschreibt eine Einziehmaschine, die Litzen auf bahnförmigen Schienen führt und mittels verschiedener Stößel bzw. Schieber transportiert und positioniert. Mittels einer drehbaren Schiene erfolgt ggf. eine Auswahl für die Transportrichtung zum Abstoßen des Webgeschirrelements auf einen vorbestimmten Webschaft. Mittels aufwändiger Führungen, die einem hohen Verschleiß unterworfen sind, wird ein Stößel entlang der drehbaren Schiene geführt.The DE69008100T2 describes a drawing-in machine that guides strands on web-shaped rails and transports and positions them using various rams or slides. A rotatable rail can be used to select the transport direction for pushing the harness element onto a predetermined heald shaft. A plunger is guided along the rotating rail using complex guides that are subject to high levels of wear.

Die WO9205303A1 offenbart eine Einziehmaschine, bei der zahlreiche Haltemittel für Litzen in regelmäßigen Abständen auf einem Träger montiert sind. Eine Litze verbleibt nach ihrer Separierung auf demselben Haltemittel über das Einziehen bis zum Abstoßen. Durch diese Vorgehensweise soll die Zuverlässigkeit der Einziehmaschine erhöht und ein modularer Aufbau ermöglicht werden. Jeder Schiene, auf die eine Litze abgestoßen werden könnte, ist ein einzeln anzusteuernder Aktuator zum Abstoßen zugeordnet.The WO9205303A1 discloses a drawing-in machine in which numerous holding means for strands are mounted on a support at regular intervals. After being separated, a strand remains on the same holding device until it is pulled in and pushed off. This approach is intended to increase the reliability of the drawing-in machine and enable a modular design. Each rail onto which a strand could be repelled is assigned an individually controlled actuator for repelling.

Die europäische Patenanmeldung mit der Anmeldnummer 19180573.8 beschreibt eine Vorrichtung zur Handhabung von Webgeschirrelementen, bei der sich zwei zyklisch bewegende Halteelemente derart unabhängig voneinander bewegen können, dass ein Halteelement sich bewegt, während das andere sich nicht bewegt. Die Halteelemente sind jeweils an einem Tragkörper, der auch ein Abstoßelement aufweist, angeordnet.The European patent application with application number 19180573.8 describes a device for handling woven harness elements, in which two cyclically moving holding elements can move independently of one another in such a way that one holding element moves while the other does not move. The holding elements are each arranged on a support body, which also has a repelling element.

Ausgehend von dem oben genannten Stand der Technik ist es die Aufgabe der vorliegenden Erfindung eine Vorrichtung zur Handhabung von Webgeschirrelementen und ein Verfahren zur Handhabung von Webgeschirrelementen anzugeben, das eine möglichst hohe Zuverlässigkeit und doch einen einfachen Aufbau bei der Handhabung der Webgeschirrelemente bietet.Based on the above-mentioned prior art, the object of the present invention is to provide a device for handling woven harness elements and a method for handling woven harness elements, which offers the highest possible reliability and yet a simple structure when handling the woven harness elements.

Die erfindungsgemäße Vorrichtung zur Handhabung von Webgeschirrelementen weist ein erstes Halteelement auf. Das erste Halteelement ist dazu eingerichtet, zyklisch zwischen einer Bereitstellungseinrichtung und einer Aufnahmeeinrichtung bewegt zu werden. Das erste Halteelement ist an einer Trägereinrichtung angeordnet. An der Trägereinrichtung ist außerdem ein Abstoßelement zum Abstoßen eines Webgeschirrelements von dem Halteelement auf eine Teileinrichtung der Aufnahmeeinrichtung angeordnet. Das erste Haltelement ist vorzugsweise eingerichtet seine zyklische Bewegung in einer Ebene durchzuführen, auf der eine Achse senkrecht steht.The device according to the invention for handling woven harness elements has a first holding element. The first holding element is designed to be moved cyclically between a provision device and a receiving device. The first holding element is arranged on a carrier device. A repelling element for repelling a weaving harness element from the holding element onto a sub-device of the receiving device is also arranged on the carrier device. The first holding element is preferably set up to carry out its cyclic movement in a plane on which an axis is perpendicular.

Durch die Integration eines Abstoßelements in eine Trägervorrichtung eines Halteelements kann das Abstoßelement ein an dem Halteelement angeordnetes Webgeschirrelement mit hoher Zuverlässigkeit abwerfen. Gleichzeitig ermöglicht die Integration einen einfachen Aufbau der Vorrichtung mit einer geringen Anzahl zu schaltender Aktuatoren.By integrating a repelling element into a carrier device of a holding element, the repelling element can be arranged on the holding element Shedding weave harness element with high reliability. At the same time, the integration enables a simple structure of the device with a small number of actuators to be switched.

Das Halteelement kann stiftförmig oder stabförmig ausgebildet sein. Das Halteelement kann dazu eingerichtet sein, in eine Endöse eines Webgeschirrelements, insbesondere einer Litze, einzugreifen. Das Halteelement kann eine Längserstreckung aufweisen, die zumindest ausreichend ist, eine Webgeschirrelement unter Beachtung aller Toleranzen sicher aufnehmen zu können. Das Halteelement kann aus einem Stahl bestehen, um durch den Kontakt mit den Webgeschirrelementen nicht schnell zu verschleißen.The holding element can be pin-shaped or rod-shaped. The holding element can be designed to engage in an end eyelet of a weaving harness element, in particular a heddle. The holding element can have a longitudinal extent that is at least sufficient to be able to securely hold a weaving harness element while taking into account all tolerances. The holding element can be made of steel in order not to wear out quickly due to contact with the weaving harness elements.

Eine Bereitstellungseinrichtung kann eine oder mehrere schienenartige Teileinrichtungen aufweisen, um Webgeschirrelemente zu deren Einzug bereitzustellen. Die Bereitstellungseinrichtung kann eine oder mehrere Abteileinrichtungen zum Vereinzeln von Webgeschirrelementen aufweisen. Die Bereitstellungseinrichtung kann eine Teileinrichtung eines Litzenmoduls sein.A provision device can have one or more rail-like sub-devices in order to provide weaving harness elements for their collection. The provision device can have one or more compartment devices for separating woven harness elements. The provision device can be a partial device of a stranded module.

Eine Trägereinrichtung kann unter Anderem zum Einleiten der Bewegung des Halteelements dienen, indem die Trägereinrichtung mit einem Aktuator wirkverbunden ist. Vorteilhaft kann die Trägereinrichtung um eine Achse drehbar angeordnet sein. Die Bahnkurve der zyklischen Bewegung des ersten Halteelements kann einer Kreisbahn, die eine Kreisfläche umschließt, folgen und durch die Mittelsenkrechte auf der Kreisfläche eine Achse bestimmt sein. Die Trägereinrichtung kann elektromotorisch angetrieben sein. Jeder Trägereinrichtung kann im Falle mehrerer Trägereinrichtungen ein separater Elektromotor zugeordnet sein.A carrier device can be used, among other things, to initiate the movement of the holding element by the carrier device being operatively connected to an actuator. The carrier device can advantageously be arranged so that it can rotate about an axis. The trajectory of the cyclic movement of the first holding element can follow a circular path that encloses a circular area and an axis can be determined by the bisector on the circular area. The carrier device can be driven by an electric motor. In the case of several carrier devices, each carrier device can be assigned a separate electric motor.

Das Abstoßelement kann durch einen an der Trägereinrichtung angeordneten mechanischen Aktuator bewegbar zu der Trägereinrichtung angeordnet sein. Das Abstoßelement kann ein Vorspannelement umfassen, das derart angeordnet ist, dass das Abstoßelement mittels des Vorspannelements von einem feststehenden Vorrichtungselement in Relation zur Trägereinrichtung in eine zurückgezogene Position verschoben werden kann, wenn die Trägereinrichtung an dem feststehenden Vorrichtungselement vorbei bewegt wird. Durch diese Anordnung wird in dem mechanischen Aktuator eine mechanische Spannung aufgebaut, wenn die Trägereinrichtung an dem feststehenden Vorrichtungselement vorbei bewegt wird. Das Abstoßelement kann einen mechanischen Aktuator umfassen, der durch eine Feder gebildet ist. Die Feder kann zum Beispiel durch die ohnehin notwendigen Bewegungen der Trägereinrichtung relativ zu dem feststehenden Vorrichtungselement vorgespannt werden.The repelling element can be arranged to be movable relative to the carrier device by a mechanical actuator arranged on the carrier device. The push-off element may comprise a biasing element arranged such that the push-off element can be displaced by means of the biasing element from a fixed device element into a retracted position in relation to the carrier device when the carrier device is moved past the fixed device element. This arrangement creates a mechanical tension in the mechanical actuator when the carrier device is moved past the fixed device element. The repelling element may include a mechanical actuator formed by a spring. The spring can, for example, be replaced by the already necessary ones Movements of the carrier device are biased relative to the fixed device element.

Das Abstoßelement kann an der Trägereinrichtung in einer zurückgezogenen Position verriegelbar angeordnet sein. Vorzugsweise wird das Abstoßelement beim Vorspannen automatisch verriegelt, zum Beispiel durch einen mechanischen Formschluß, der eingreift, wenn das Abstoßelement seine rückgezogene Position erreicht. Bei Trägereinrichtungen, die eingerichtet sind, eine Rotationsbewegung durchzuführen, kann das feststehende Vorrichtungselement vorzugsweise eine Kontaktfläche für ein Vorspannelement der Trägereinrichtung, deren Abstand in Bezug auf eine gemeinsame Achse zunimmt oder abnimmt, um das Vorspannelement, wenn es sich vorbei bewegt in radialer Richtung auszulenken und so einen mechanischen Aktuator, vorzugsweise eine Zugfeder oder eine Druckfeder, vorzuspannen. Das Vorspannelement kann einstückig mit dem Abstoßelement ausgeführt oder unbeweglich am Abstoßelement angeordnet sein.The repelling element can be arranged on the carrier device in a lockable manner in a retracted position. Preferably, the repelling element is automatically locked during prestressing, for example by a mechanical positive locking which intervenes when the repelling element reaches its retracted position. In carrier devices that are set up to carry out a rotational movement, the fixed device element can preferably have a contact surface for a biasing element of the carrier device, the distance of which increases or decreases with respect to a common axis in order to deflect the biasing element in the radial direction as it moves past and to preload a mechanical actuator, preferably a tension spring or a compression spring. The biasing element can be made in one piece with the repelling element or can be arranged immovably on the repelling element.

Die Trägereinrichtung kann ein Entriegelungselement aufweisen, das derart eingerichtet ist, dass bei einer Verschiebung des Entriegelungselements relativ zur Trägereinrichtung das Abstoßelement entriegelt wird und eine durch den mechanischen Aktuator getriebene Abstoßbewegung durchführen kann. Vorzugsweise ist das Entriegelungselement durch eine Feder vorgespannt an der Trägereinrichtung angeordnet, um das Abstoßelement mittels Formschluß automatisch zu verriegeln, wenn das Abstoßelement getrieben durch das Vorspannelement in eine rückgezogene Position gelangt.The carrier device can have an unlocking element which is set up in such a way that when the unlocking element is displaced relative to the carrier device, the push-off element is unlocked and can carry out a push-off movement driven by the mechanical actuator. Preferably, the unlocking element is arranged on the carrier device in a preloaded manner by a spring in order to automatically lock the repulsion element by means of positive locking when the repulsion element, driven by the pretensioning element, reaches a retracted position.

Ein Entriegelungsvorrichtungselement kann derart angeordnet sein, dass die Verschiebung des Entriegelungselements der Trägereinrichtung durch das in Richtung der Achse zu der Trägereinrichtung beweglich eingerichtete Entriegelungsvorrichtungselement bereitgestellt werden kann. Das Entriegelungsvorrichtungselement kann weiter derart eingerichtet sein, dass das Entriegelungselement einer Trägereinrichtung, die an einer beliebigen Teileinrichtung der Aufnahmeeinrichtung angeordnet ist, verschoben werden kann. Vorzugsweise wird bei Verschiebung des Entriegelungselements ein beim Vorspannen zustande gekommener Formschluß aufgehoben und das Abstoßelement somit entriegelt und getrieben durch die Spannung im mechanischen Aktuator ausgefahren wird. Das Entriegelungsvorrichtungselement ist vorteilhafterweise für Trägereinrichtungen, die an beliebigen Teileinrichtungen einer Handhabungsvorrichtung wie zum Beispiel der Aufnahmevorrichtung angeordnet sind, gleichzeitig wirksam, was wiederum die Anzahl von Komponenten klein hält und so die Wirtschaftlichkeit und die Zuverlässigkeit fördert. Dies kann bei um eine gemeinsame Achse rotierenden Trägereinrichtungen dergestalt eingerichtet werden, dass das Entriegelungsvorrichtungselement eine Winkelausdehnung in Rotationsrichtung der Trägereinrichtung aufweist, dass ein Entriegelungselement einer Trägereinrichtung an jeder möglichen Winkelstellung der Trägereinrichtung erfasst werden kann. Ein solches Entriegelungsvorrichtungselement kann sich bogenförmig und insbesondere kreisbogenförmig erstrecken. Ein solches Entriegelungsvorrichtungselement kann in Bezug auf eine Achse in einem radialen Abstand wirken, der dem radialen Abstand des Entriegelungselements von einem Drehmittelpunkt der Trägereinrichtung entspricht. Das Entriegelungsvorrichtungselement wirkt vorzugsweise in Richtung parallel zu der Achse. Das Entriegelungsvorrichtungselement wirkt vorzugsweise von der Seite auf die Trägereinrichtung, die der Richtung eines an der Trägereinrichtung gehaltenen Webgeschirrelements entgegengesetzt ist.An unlocking device element can be arranged in such a way that the displacement of the unlocking element of the carrier device can be provided by the unlocking device element which is designed to be movable in the direction of the axis to the carrier device. The unlocking device element can further be set up in such a way that the unlocking element of a carrier device which is arranged on any sub-device of the receiving device can be moved. Preferably, when the unlocking element is displaced, a positive connection that occurred during prestressing is canceled and the repelling element is thus unlocked and driven out by the tension in the mechanical actuator. The unlocking device element is advantageously effective at the same time for carrier devices that are arranged on any sub-devices of a handling device such as the receiving device, which in turn keeps the number of components small and thus promotes economy and reliability. This With carrier devices rotating about a common axis, it can be set up in such a way that the unlocking device element has an angular extent in the direction of rotation of the carrier device, so that an unlocking element of a carrier device can be detected at every possible angular position of the carrier device. Such an unlocking device element can extend in an arc shape and in particular in a circular arc shape. Such an unlocking device element can act with respect to an axis at a radial distance which corresponds to the radial distance of the unlocking element from a center of rotation of the carrier device. The unlocking device element preferably acts in a direction parallel to the axis. The unlocking device element preferably acts on the carrier device from the side, which is opposite to the direction of a weaving harness element held on the carrier device.

An der Trägereinrichtung ist ein Anschlagelement angeordnet, das der Abstoßbewegung des Abstoßelements im Bereich dessen ausgefahrenen Endlage entgegengerichtet ist. Das Anschlagelement ist ferner dazu eingerichtet, das Abstoßelement aus der ausgefahrenen Endlage seiner Abstoßbewegung zurückdrängen zu können. Durch das Anschlagelement kann verhindert werden, dass das Abstoßelement wieder in Kontakt zu bereits abgestoßenen Webgeschirrelementen kommt. So kann die Zuverlässigkeit nochmals erhöht werden. Vorzugsweise kann dem Anschlagelement eine Feder zugeordnet sein, die durch das auftreffende Abstoßelement zusammengedrückt wird und das Abstoßelement durch eine von der Feder getriebene Kraft aus seiner Endlage zurückverlagert. Das Abstoßelement kann durch das Anschlagelement maximal 10% oder 20% seiner Strecke der Abstoßbewegung aus seiner Endlage zurückverlagert werden.A stop element is arranged on the carrier device and is directed in the opposite direction to the push-off movement of the push-off element in the area of its extended end position. The stop element is also designed to be able to push the push-off element back from the extended end position of its push-off movement. The stop element can prevent the repelling element from coming into contact again with woven harness elements that have already been repelled. In this way, reliability can be increased again. Preferably, a spring can be assigned to the stop element, which is compressed by the impacting repelling element and moves the repelling element back from its end position by a force driven by the spring. The push-off element can be moved back from its end position by a maximum of 10% or 20% of the distance of the push-off movement by the stop element.

Dem ersten Halteelement kann ein ergänzendes Halteelement in einem Abstand entlang der Achse zugeordnet sein. Das erste Haltelement und/oder das ergänzende Halteelement kann beweglich an einer Trägereinrichtung angeordnet sein, um ein Webgeschirrelement unter Zugspannung zwischen dem ersten Halteelement und dem ergänzenden Halteelement halten zu können. Damit werden störende Bewegungen des Webgeschirrelements zwischen den Halteelementen zumindest teilweise unterdrückt und die Zuverlässigkeit der Vorrichtung erhöht. Der besagte axiale Abstand ist einstellbar und kann an die Länge eines Webgeschirrelements angepasst werden. Vorzugsweise ist ein bewegliches Halteelement so an einer Trägereinrichtung angeordnet, dass das Webgeschirrelement vorgespannt ist, wenn keine externe Kraft angreift.The first holding element can be assigned a supplementary holding element at a distance along the axis. The first holding element and/or the supplementary holding element can be movably arranged on a support device in order to be able to hold a weaving harness element under tension between the first holding element and the supplementary holding element. This means that disruptive movements of the weaving harness element between the holding elements are at least partially suppressed and the reliability of the device is increased. Said axial distance is adjustable and can be adapted to the length of a weaving harness element. Preferably, a movable holding element is arranged on a support device in such a way that the weaving harness element is prestressed when no external force is applied.

Vorzugsweise kann ein Entspannungsvorrichtungselement an der Vorrichtung angeordnet sein, das ergänzende Halteelement oder ein dem Halteelement zugeordnetes Entspannungsdruckelement mit einer Verschiebung beaufschlagen zu können. Die Verschiebung erfolgt vorzugsweise parallel zu der Richtung der Achse. Ein beweglich an der Trägereinrichtung angeordnetes ergänzendes Halteelement kann um eine Lagerachse des Halteelements schwenkbar an der Trägereinrichtung angeordnet sein. Das Entspannungsvorrichtungselement kann wie das Entriegelungsvorrichtungselement eine Winkelerstreckung aufweisen, so dass ein Halteelement an jeder Teileinrichtung der Aufnahmeeinrichtung mit einer Verschiebung beaufschlagt werden kann. Ein zusätzliches, gleichwirkendes Entspannungsvorrichtungselement kann auch der Bereitstellungsvorrichtung zugeordnet sein. Für die Richtung der Verschiebung des Entspannungsvorrichtungselements gilt dasselbe wie für das Entriegelungsvorrichtungselement. Insbesondere können das Entspannungsvorrichtungselement und das Entriegelungsvorrichtungselement an der Aufnahmevorrichtung einstückig ausgebildet sein, was wiederum die Teilezahl verringert und die Zuverlässigkeit erhöht. Vorzugsweise wirkt jedenfalls das Entspannungsvorrichtungselement zeitlich vor dem Entriegelungsvorrichtungselement.Preferably, a relaxation device element can be arranged on the device so that the additional holding element or a relaxation pressure element assigned to the holding element can be subjected to a displacement. The displacement preferably occurs parallel to the direction of the axis. A supplementary holding element movably arranged on the carrier device can be arranged on the carrier device so as to be pivotable about a bearing axis of the holding element. Like the unlocking device element, the relaxation device element can have an angular extension, so that a holding element on each sub-device of the receiving device can be subjected to a displacement. An additional relaxation device element with the same effect can also be assigned to the provision device. The same applies to the direction of displacement of the relaxation device element as to the unlocking device element. In particular, the relaxation device element and the unlocking device element can be formed in one piece on the receiving device, which in turn reduces the number of parts and increases reliability. In any case, the relaxation device element preferably acts before the unlocking device element.

Die erfindungsgemäße Vorrichtung kann insbesondere ein Modul wie ein Litzenmodul einer modular aufgebauten Einziehmaschine sein. Das Modul kann bevorzugt sowohl mechanisch wie auch elektrisch von der Einziehmaschine getrennt werden, ohne dass die Funktion anderer Module beeinträchtigt wird. Ebenso kann das Modul in einer bevorzugten Ausführungsform seine Funktionen ausführen, wenn andere Module deaktiviert oder gar demontiert sind. Die Bereitstellungseinrichtung des Litzenmoduls kann eine oder mehrere Teileinrichtungen aufweisen, an denen das Haltelement eine Litze aus einem Vorrat übernehmen kann. Das Halteelement kann ein Webgeschirrelement wie eine Litze zu verschiedenen Handhabungseinrichtungen bewegen. Dies können eine Einzugsvorrichtung, eine Messeinrichtung, eine Kennzeichnungseinrichtung, eine Auswurfeinrichtung, eine Aufnahmeeinrichtung oder weitere sein. Eine Einzugsvorrichtung kann dazu dienen ein Garn in ein Fadenauge einer Litze einzuziehen. Mittels einer Messeinrichtung können Litzen nach ihrer Qualität eingestuft und bei Bedarf zum Beispiel entsprechend gekennzeichnet (Kennzeichnungseinrichtung) oder aussortiert (Auswurfeinrichtung) werden. Typischerweise werden Litzen, in die ein Garn eingezogen wurde, auf eine von meist mehreren einzelnen Teileinrichtungen einer Aufnahmeeinrichtung abgestoßen. Diese Teileinrichtungen einer Aufnahmeeinrichtung können Tragschienen von Webschäften oder schienenartige Führungen, die solchen Tragschienen zugeordnet sind, sein. Die Aufnahmeeinrichtung kann eine Teileinrichtung einer Einziehmaschine sein. Die Aufnahmeeinrichtung kann eine Teileinrichtung eines Geschirrwagens sein.The device according to the invention can in particular be a module such as a strand module of a modular drawing-in machine. The module can preferably be separated from the drawing machine both mechanically and electrically without affecting the function of other modules. Likewise, in a preferred embodiment, the module can carry out its functions when other modules are deactivated or even dismantled. The provision device of the strand module can have one or more sub-devices on which the holding element can take a strand from a supply. The holding element can move a weaving harness element such as a strand to various handling devices. This can be a feed device, a measuring device, a marking device, an ejection device, a receiving device or others. A drawing-in device can be used to draw a yarn into a thread eye of a strand. Using a measuring device, strands can be classified according to their quality and, if necessary, marked accordingly (marking device) or sorted out (ejection device). Typically, strands into which a yarn has been drawn are pushed onto one of usually several individual sub-devices of a receiving device. These sub-devices of a receiving device can be support rails of heald frames or rail-like guides, which are assigned to such mounting rails. The receiving device can be a partial device of a drawing-in machine. The receiving device can be a part of a dish trolley.

Bei der Durchführung des erfindungsgemäßen Verfahrens zur Handhabung von Webgeschirrelementen bewegt sich ein erstes Halteelement zyklisch zwischen einer Bereitstellungseinrichtung und einer Aufnahmeeinrichtung. Das erste Haltelement führt seine zyklische Bewegung in einer Ebene durch, auf der eine Achse senkrecht steht. Das erste Halteelement ist an einer Trägereinrichtung angeordnet. Erfindungsgemäß stößt ein an der Trägereinrichtung außerdem angeordnetes Abstoßelement ein Webgeschirrelement, das an dem Halteelement angeordnet ist, auf eine Teileinrichtung der Aufnahmeeinrichtung ab.When carrying out the method according to the invention for handling woven harness elements, a first holding element moves cyclically between a provision device and a receiving device. The first holding element carries out its cyclic movement in a plane on which an axis is perpendicular. The first holding element is arranged on a carrier device. According to the invention, a repelling element, which is also arranged on the carrier device, repels a weaving harness element, which is arranged on the holding element, onto a sub-device of the receiving device.

Durch das simultane Bewegen des Haltelements mit dem Webgeschirrelement und des Abstoßelements wird ein besonders zuverlässiges Abstoßen des Webgeschirrelements mit einem besonders einfachen Aufbau, der wenig zu steuernde Teile umfasst, ermöglicht. Ein Abstoßen kann nicht scheitern, weil das Haltemittel das Webgeschirrelement nicht korrekt vor einem einer Teileinrichtung einer Aufnahmevorrichtung zugeordneten Abstoßelement positioniert oder weil ein entsprechendes Abstoßelement nicht korrekt ausgelöst wird.The simultaneous movement of the holding element with the weaving harness element and the repelling element enables a particularly reliable repelling of the weaving harness element with a particularly simple structure that includes few parts that need to be controlled. A repulsion cannot fail because the holding means does not correctly position the weaving harness element in front of a repulsion element assigned to a sub-device of a receiving device or because a corresponding repulsion element is not triggered correctly.

Das erste Haltelement bewegt sich vorzugsweise auf einer Kreisbahn, die eine Kreisfläche umschließt und durch die Mittelsenkrechte auf der Kreisfläche ist eine Achse bestimmt.The first holding element preferably moves on a circular path that encloses a circular area and an axis is determined by the bisector on the circular area.

Die Trägereinrichtung des ersten Halteelements kann sich an einem feststehenden Vorrichtungselement vorbei bewegen, um das Abstoßelement relativ zu der Trägereinrichtung zu verschieben.The carrier device of the first holding element can move past a fixed device element in order to displace the repelling element relative to the carrier device.

Ein Entriegelungsvorrichtungselement kann sich in Richtung der Achse relativ zu der an einer Teileinrichtung der Aufnahmeeinrichtung angeordneten Trägereinrichtung bewegen und ein an der Trägereinrichtung angeordnetes Entriegelungselements relativ zu der Trägereinrichtung verschieben, so dass das Abstoßelement ein Webgeschirrelement, das an dem Halteelement angeordnet ist, auf eine Teileinrichtung der Aufnahmeeinrichtung abstößt.An unlocking device element can move in the direction of the axis relative to the carrier device arranged on a sub-device of the receiving device and can move an unlocking element arranged on the carrier device relative to the carrier device, so that the repelling element pushes a weaving harness element, which is arranged on the holding element, onto a sub-device of the Recording device repels.

An der Bereitstellungseinrichtung kann das erste Haltelement und/oder das ergänzende Halteelement durch ein Entspannungsvorrichtungselement in Richtung parallel zu der Achse verschoben werden, um ein Webgeschirrelement aufnehmen zu können.

Figur 1 zeigt eine symbolische Schrägansicht wesentlicher Komponenten der erfindungsgemäßen Vorrichtung 1. Längs der Achse 14 ist in einem oberen Bereich der Vorrichtung 1 das Halteelement 2 in 2 unterschiedlichen Positionen dargestellt. In einem unteren Bereich der Vorrichtung 1 ist das ergänzende Halteelement 3 in zwei verschiedenen Positionen dargestellt. Die Halteelemente 2 und 3 sind dazu eingerichtet nicht dargestellte Webgeschirrelemente von einer Bereitstellungsvorrichtung 4 links in der Figur 1 zu einer Aufnahmeeinrichtung 5 rechts in der Figur 1 zu transportieren. Die dargestellte Bereitstellungsvorrichtung 4 umfasst oben zwei Teileinrichtungen 41 und 42, die als Schienen dargestellt sind. Die dargestellte Bereitstellungsvorrichtung 4 umfasst unten zwei Teileinrichtungen bzw. Schienen 43 und 44, auf denen Webgeschirrelemente breitgestellt und von dem Halteelement 3 aufgenommen werden können. Die dargestellte Aufnahmevorrichtung 5 umfasst oben zwei Teileinrichtungen bzw. Schienen 51 und 52 und unten zwei Schienen 53 und 54, auf denen die eingezogenen Webgeschirrelemente angegeben werden können. Sowohl die Bereitstellungsvorrichtung 4 als auch die Aufnahmevorrichtung 5 können jeweils unabhängig voneinander in allen denkbaren Ausführungsbeispielen eine unterschiedliche Zahl an Schienen oder allgemein Teileinrichtungen aufweisen, deren Zahl von 1 bis zum Beispiel bis zu 20 reichen kann. Figure 1 shows a symbolic oblique view of essential components of the device 1 according to the invention. Along the axis 14, the holding element 2 is shown in 2 different positions in an upper region of the device 1. In a lower area of the device 1, the additional holding element 3 is shown in two different positions. The holding elements 2 and 3 are set up for weaving harness elements, not shown, from a provision device 4 on the left in the Figure 1 to a recording device 5 on the right in the Figure 1 to transport. The delivery device 4 shown comprises two sub-devices 41 and 42 at the top, which are shown as rails. The provision device 4 shown comprises two sub-devices or rails 43 and 44 at the bottom, on which weaving harness elements can be spread out and picked up by the holding element 3. The receiving device 5 shown comprises two sub-devices or rails 51 and 52 at the top and two rails 53 and 54 at the bottom, on which the retracted weaving harness elements can be specified. Both the provision device 4 and the receiving device 5 can each have, independently of one another, a different number of rails or generally partial devices in all conceivable exemplary embodiments, the number of which can range from 1 to, for example, up to 20.

Das erste Halteelement 2 ist an einer Trägereinrichtung 6 angeordnet. Das ergänzende Haltelement 3 ist an der Trägereinrichtung 7 angeordnet. Die Trägereinrichtungen 6 und 7 sind drehbar um die Achse 14 angeordnet. Das erste Halteelement 2 und das ergänzende Halteelement 3 können eine Litze an deren Endösen vorgespannt von der Bereitstellungsvorrichtung 4 zu der Aufnahmevorrichtung 5 transportieren. Dazu ist das Halteelement 3 beweglich an der Trägereinrichtungen 7 angebracht, was durch die Lagerachsen 17 angedeutet ist. Um die Vorspannung der Litzen aufzuheben, kann das Halteelement 3 mit den Entspannungsvorrichtungselementen 16 in der Figur 1 nach oben verschoben werden. Das in der Figur 1 rechts dargestellte Entspannungsvorrichtungselement 16 ist einstückig mit einem Entriegelungsvorrichtungselement 12 ausgeführt. So kann eine Litze im spannungsfreien Zustand von dem Abstoßelement 9 der Trägereinrichtungen 6 und 7 auf eine Schiene 52 und 54 der Aufnahmevorrichtung abgegeben werden. Die Abstoßelemente 9 sind entsprechend in ausgefahrenem Zustand gezeigt. Die Abstoßelemente 8 sind im gespanntem Zustand dargestellt. Im dargestellten Ausführungsbeispiel drehen die Trägereinrichtungen 6 und 7 zunächst von den Schienen 52 und 54 weiter zu den Schienen 51 und 53. Dann passieren die Trägereinrichtungen 6 und 7 die feststehenden Vorrichtungselemente 10, die mit den Vorspannelementen 15 in Eingriff gelangen und die Abstoßelemente 9 so aus dem ausgefahrenen Zustand (dargestellt wie Abstoßelemente 9) in den gespannten Zustand (dargestellt wie Abstoßelemente 8) überführen, wie dies bei den Trägereinrichtungen 6 und 7 im linken Teil der Figur 1 dargestellt ist.The first holding element 2 is arranged on a carrier device 6. The additional holding element 3 is arranged on the carrier device 7. The carrier devices 6 and 7 are rotatable about the axis 14. The first holding element 2 and the additional holding element 3 can transport a strand pre-tensioned at its end eyelets from the provision device 4 to the receiving device 5. For this purpose, the holding element 3 is movably attached to the support devices 7, which is achieved by the Bearing axes 17 is indicated. In order to cancel the pre-tension of the strands, the holding element 3 can be connected to the relaxation device elements 16 in the Figure 1 be moved up. That in the Figure 1 Relaxation device element 16 shown on the right is designed in one piece with an unlocking device element 12. In this way, a stranded wire can be released from the repelling element 9 of the carrier devices 6 and 7 onto a rail 52 and 54 of the receiving device in a tension-free state. The repelling elements 9 are accordingly shown in the extended state. The repelling elements 8 are shown in the tensioned state. In the exemplary embodiment shown, the carrier devices 6 and 7 first rotate from the rails 52 and 54 to the rails 51 and 53. Then the carrier devices 6 and 7 pass the fixed device elements 10, which come into engagement with the prestressing elements 15 and the repelling elements 9 in this way from the extended state (shown like repelling elements 9) to the tensioned state (shown like repelling elements 8), as is the case with the carrier devices 6 and 7 in the left part of the Figure 1 is shown.

Die Entriegelungsvorrichtungselemente 12 wirken mit Entriegelungselementen 11 zusammen, um die Abstoßelemente 8 zu entriegeln und so von dem gespannten Zustand (dargestellt wie Abstoßelemente 8) in den ausgefahrenen Zustand (dargestellt wie Abstoßelemente 9) zu überführen. Dazu führen die Entriegelungsvorrichtungselemente 12 eine Bewegung parallel zu der Achse 14 aus. An jeder Trägereinrichtung 6 und 7 sind zwei Entriegelungselemente 11 gezeigt. In anderen Ausführungsbeispielen kann auch nur ein Entriegelungselement 11 an der Trägereinrichtung 6 oder 7 angeordnet sein.The unlocking device elements 12 cooperate with unlocking elements 11 to unlock the push-off elements 8 and thus transfer them from the tensioned state (shown like push-off elements 8) to the extended state (shown like push-off elements 9). For this purpose, the unlocking device elements 12 carry out a movement parallel to the axis 14. Two unlocking elements 11 are shown on each carrier device 6 and 7. In other exemplary embodiments, only one unlocking element 11 can be arranged on the carrier device 6 or 7.

Figur 2 zeigt eine symbolische Darstellung einer alternativen Trägereinrichtung 7 für ein ergänzendes Halteelement 3 in Frontansicht mit teilweiser Anzeige verdeckter Kanten durch gestrichelte Linien und Angabe einer Schnittlinie D:D. Das Abstoßelement 8 ist im gespanntem Zustand gezeigt. Seitlich am Abstoßelement 8 sind zwei Führungsnasen 19 zu erkennen, mit denen eine Längsführung der Abstoßelements 8 bewerkstelligt werden kann. Zusätzlich können die Führungsnasen 19 dazu verwendet werden mit einer umlaufenden Nut 18 des Entriegelungselements 11 bei entsprechender gegenseitiger Anordnung einen Formschluß zum Verriegeln des Abstoßelementes 8 herzustellen. Die Nut 18 des Entriegelungselements 11 ist in Figur 3 zu erkennen. Figure 2 shows a symbolic representation of an alternative support device 7 for a supplementary holding element 3 in a front view with partial display of hidden edges by dashed lines and indication of a cutting line D:D. The repelling element 8 is shown in the tensioned state. On the side of the push-off element 8, two guide lugs 19 can be seen, with which longitudinal guidance of the push-off element 8 can be achieved. In addition, the guide lugs 19 can be used to produce a positive connection with a circumferential groove 18 of the unlocking element 11 with a corresponding mutual arrangement for locking the repelling element 8. The groove 18 of the unlocking element 11 is in Figure 3 to recognize.

Figur 3 zeigt den Schnitt D:D aus Figur 2. der Figur 3 ist die bewegliche Lagerung des Halteelements 3 an der Trägereinrichtung 7 mittels einer Lagerachse 17 zu entnehmen. Das Abstoßelement 8 ist in seiner zurückgezogenen und gespannten Position, in die es mithilfe des Vorspannelements 15 überführt wurde, dargestellt. Ferner zeigt Figur 3 ein Entspannungsdruckelement 13, das am Halteelement 3 angeordnet ist. Das Entriegelungselement 11 kann gegenüber der Trägereinrichtung 7 mit einer nicht dargestellten Feder gespannt sein, so dass beim Zurückziehen des Abstoßelements 8 ein Formschluß mit dem Entriegelungselement 11 automatisch zustande kommen kann. Figure 3 shows the section D:D Figure 2 . the Figure 3 the movable mounting of the holding element 3 on the carrier device 7 can be seen by means of a bearing axle 17. The repelling element 8 is in its retracted and tensioned position, into which it is moved using the Biasing element 15 was transferred, shown. Furthermore shows Figure 3 a relaxation pressure element 13, which is arranged on the holding element 3. The unlocking element 11 can be tensioned relative to the carrier device 7 with a spring, not shown, so that a positive connection with the unlocking element 11 can occur automatically when the repelling element 8 is retracted.

Figur 4 zeigt bis auf die gestrichelten Linien, mit denen in Figur 3 verdeckte Kanten gezeigt sind, dieselben Elemente wie die Figur 2, allerdings sind Schnittlinien B:B dargestellt. Der Schnitt B:B ist in Figur 5 dargestellt. Ausser dem Haltemittel 3 und dem Abstoßelement 8 ist an der Trägereinrichtung 7 eine Bohrung 20 zu erkennen. Zwischen der Bohrung 20 und dem Stift 21, der in Figur 4 zu erkennen ist, kann eine nicht dargestellte Feder angeordnet werden, um das Halteelement in Figur 5 nach unten zu spannen. Damit kann auf ein nicht dargestelltes Webgeschirrelement eine Zugspannung aufgebracht werden, wenn das Webgeschirrelement auch an einem in Figur 5 nicht dargestellten, oberhalb des Haltelements 3 angeordneten Haltelement 2, angeordnet ist. Am Abstoßelement ist ein Durchgang 22 zu erkennen. Am Durchgang 22 kann eine nicht dargestellte Feder befestigt sein, die mit ihrem anderen Ende an einem Befestigungselement 23 befestigt sein kann, um das Abstoßelement 8 zu seiner Abstoßbewegung zu veranlassen. Das Befestigungselement 23 ist fest an der Trägereinrichtung 7 angeordnet. Figure 4 shows except for the dashed lines with which in Figure 3 hidden edges are shown, the same elements as the Figure 2 , but cutting lines B:B are shown. The cut B:B is in Figure 5 shown. In addition to the holding means 3 and the repelling element 8, a hole 20 can be seen on the carrier device 7. Between the hole 20 and the pin 21, which is in Figure 4 can be seen, a spring, not shown, can be arranged to hold the holding element in Figure 5 to tension downwards. This means that a tensile stress can be applied to a weaving harness element, not shown, if the weaving harness element is also attached to an in Figure 5 holding element 2, not shown, arranged above the holding element 3, is arranged. A passage 22 can be seen on the repelling element. A spring, not shown, can be attached to the passage 22, the other end of which can be attached to a fastening element 23 in order to cause the repelling element 8 to move. The fastening element 23 is fixedly arranged on the carrier device 7.

Es wird ausdrücklich darauf hingewiesen, dass die einzelnen gezeigten Merkmale an anderen Ausführungsbeispielen einzeln oder insgesamt unabhängig voneinander abweichend gelöst werden können, solange sich diese Lösungen im Rahmen der Merkmale der der Anmeldung zugrunde liegenden Ansprüche bewegen. So kann ein Formschluß zwischen Abstoßelement 8 und Entriegelungselement 11 unabhängig von Führungsnasen 19 hergestellt werden.
