Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Erzeugen von sortenreinem Schussfadenabfall bei der Gewebeherstellung auf Webmaschinen und zur wahlweisen Wiederverwendung des Kettmaterials aus einer mit einem Rotations-Kantendreher hergestellten Fangleiste, wobei der die Dreherfäden führende Rotationskörper des Rotations-Kantendrehers in seiner Drehrichtung vorzugsweise umkehrbar ist.The invention relates to a method and an apparatus for producing single-variety Weft thread waste in the manufacture of fabrics on weaving machines and optionally Reuse the warp material from one with a rotary edge driver produced catch strip, the rotating body of the rotary edge driver guiding the leno threads is preferably reversible in its direction of rotation.

Bekannt ist aus der EP 0 127 719 A1 eine Vorrichtung zum Abziehen der von einem auf Webmaschinen hergestellten Gewebe abgetrennten Hilfskante, die gelegentlich als Gewebeleiste oder Fangleiste bezeichnet wird.
Die nahe der Warenabzugswalze einer Webmaschine angeordnete Vorrichtung besitzt einen mit einer Injektordüse ausgestatteten Hilfskanten-Abziehkanal.
Die aus Kette und Schuss bestehende Hilfskante wird pneumatisch mittels der Vorrichtung einem Abfallbehälter zugeführt, ohne dass die Kettfäden und Schussfäden zwecks Erhalt eines sortenreinen Abfalls in irgendeiner Weise ab Webmaschine sortiert würden.Known from EP 0 127 719 A1 is a device for pulling off the auxiliary edge separated from a fabric produced on weaving machines, which is sometimes referred to as a fabric strip or catch strip.
The device arranged near the goods take-off roller of a weaving machine has an auxiliary edge pull-off channel equipped with an injector nozzle.
The auxiliary edge consisting of warp and weft is pneumatically fed to a waste container by means of the device, without the warp threads and weft threads being sorted in any way from the weaving machine in order to obtain a sorted waste.

Ferner ist aus der EP 0 681 044 A1 ein Verfahren zum Abziehen von Abfallkanten und eine Abzugseinrichtung zum Durchführen des Verfahrens bekannt, wonach die beim Weben auf einer Webmaschine gebildete Abfallkante zwischen zwei angetriebenen Abzugswalzen, die eine Klemmstelle für die Abfallkante bilden, hindurch in einen Abfallbehälter geleitet wird. Die aus Kette und Schuss bestehende Abfallkante wird hier also mit mechanischen Mittel dem Abfall zugführt, ohne dass ein Trennprozess zwecks Erhalt eines sortenreinen Schussmaterialabfalls und eines sortenreinen Kettmaterialabfalls ab Webmaschine erfolgen würde.Furthermore, EP 0 681 044 A1 describes a method for removing waste edges and one Draw-off device for carrying out the method is known, after which the weaving on a loom formed between two driven take-off rollers, the form a clamping point for the waste edge, is passed through into a waste container. The waste edge consisting of warp and weft is here with mechanical means fed to the waste without a separation process to obtain a single-variety Weft material waste and pure warp material waste are carried out from the weaving machine would.

Schließlich ist aus der DE 297 08 758 U1 eine Webmaschine bekannt, auf der die Kanten eines herzustellenden Gewebes und die Fangleisten durch sogenannte Rotations-Kantendreher realisiert werden.
Im Gegensatz zu dem zuvor genannten bekannten technischen Lehren werden hier die Schussfäden zum Ausbilden der Fangleiste durch lediglich zwei Dreherfäden mittels des Rotations-Kantendrehers abgebunden, um so die Fangleiste bzw. die Abfallkante zu bilden. Über die weitere Behandlung oder Verwendung der von der Gewebekante abgetrennten Fangleiste gibt diese Druckschrift keine Auskunft.Finally, a weaving machine is known from DE 297 08 758 U1, on which the edges of a fabric to be produced and the catch strips are realized by so-called rotary edge rotators.
In contrast to the known technical teachings mentioned above, the weft threads for forming the catch strip are tied here by means of only two leno threads by means of the rotary edge rotator, so as to form the catch strip or the waste edge. This publication does not provide any information about the further treatment or use of the catch strip separated from the fabric edge.

Ein sortenreiner Schussfadenabfall kann nicht in jedem Fall mit diesem Rotations-Kantendreher erzielt werden, da gerade bei reißkraftarmen Garnen, wie z.B. Kaschmirgarnen, kein Kaschmirgarn für den Dreherfaden verwendet werden kann, weil dieses Garn in seiner Struktur zu schwach ist. Dreherfadenbrüche wären die Folge, die dann zu Webmaschinenstillständen führen.
Um diese Unzulänglichkeit zu beseitigen, wird bis gegenwärtig als Dreherfaden ein Wollzwirn verwendet, der in seiner Qualität den Beanspruchungen in dem Rotations-Kantendreher standhält. Ein solcher Wollzwirn trägt aber u.U. nicht zur Sortenreinheit der Fangleiste bei. Ein solcher Abfall ist daher weniger wertvoll und bezüglich seiner Wiederverwendung in einer Spinnerei ungeeignet.A pure weft thread waste cannot always be achieved with this rotary edging screwdriver, because especially with low tensile strength yarns, such as cashmere yarns, cashmere yarn cannot be used for the leno thread, because this yarn is too weak in its structure. This would result in leno thread breaks, which would then lead to loom downtimes.
In order to remedy this inadequacy, a wool thread is used as the leno thread, which withstands the stresses in the rotary edging machine in its quality. Such a thread of wool may not contribute to the purity of the safety catch. Such waste is therefore less valuable and unsuitable for reuse in a spinning mill.

Ein Verfahren und eine Vorrichtung zur Bildung einer zeitweilig vorhandenen Fangleiste an einem auf schützenlosen Webmaschinen herzustellenden Gewebe ist aus dem Dokument DE 30 25 744 A1 bekannt.A method and an apparatus for forming a temporary catch rail A fabric to be produced on defenseless weaving machines is known from document DE 30 25 744 A1 known.

Der Gegenstand des vorbekannten Dokuments stellt u.a. darauf ab, den mit dem Ausbilden eine Fangleiste einhergehenden Garnabfall zu reduzieren. Dies soll dadurch erfolgen, dass einer Vorrichtung zum Abbinden der Schussfäden in der Fangleiste eine ähnliche oder gleiche Vorrichtung nachgeordnet wird, die bindungsgleich die zuvor erfolgten Abbindungen wieder auflöst und daraufhin die Schussfadenenden mittels einer geeigneten Vorrichtung aus der Fangleiste entfernt werden.The subject of the previously known document provides, inter alia, depends on the one with training one Catch strip to reduce accompanying yarn waste. This should be done by one Device for tying the weft threads in the catch strip a similar or the same Subordinate device that binds the previously made ties again dissolves and then the weft ends by means of a suitable device from the Catch bar can be removed.

Die von den Verkreuzungen befreiten Dreherfäden sind Endlosfäden, die der fangleistenbildenden Vorrichtung wieder zugeführt werden.The leno threads freed from the crossings are continuous threads, which the catch bar forming device are fed again.

Beim Auflösen der Fangleiste werden die Schussfadenenden durch einen oder mehrere Saugdüsen erfasst und dem Abfall zugeführt. Ein sortenreiner Abfall wird dann nicht realisiert, wenn Schussfadenmaterial verschiedener Qualität verarbeitet wird.When the catch strip is released, the weft ends are replaced by one or more Suction nozzles recorded and fed to the waste. Pure waste is then not realized, when weft material of different quality is processed.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, womit erstens ein absolut sortenreiner Schussfadenabfall aus Fangleisten im Webprozess erzielt werden kann, der 100 %ig wiederverwendbar ist und wonach zweitens die zur Fangleistenbildung verwendeten Dreherfäden als solche wahlweise erneut als Dreherfäden verwendet werden können.The invention is therefore based on the object of a method and a device create, with which, firstly, an absolutely pure weft waste from catch strips in the Weaving process can be achieved that is 100% reusable and secondly the leno threads used to form the catch strips as such optionally again as Leno threads can be used.

Erfindungsgemäß wird die Aufgabe durch die Merkmale der Ansprüche 1 und 8 gelöst.
Danach werden nach dem Trennen der Fangleiste vom Gewebe diese einem Rotationskörper zugeführt, der wenigstens im Hinblick auf seine Ansteuerung mit dem Antrieb des Rotations-Kantendrehers gleichgeschaltet ist und dadurch ein Aufzwirnen bzw. Aufdrehen der Volldreherbindung der Fangleiste erfolgt.
Durch den synchronen bzw. asynchronen Lauf zwischen dem die Fangleiste aufzwirnenden Rotationskörper und dem Rotations-Kantendreher wird es erstmals möglich, die mittels eines Rotations-Kantendrehers hergestellte Volldreherbindung einer Fangleiste aufzudrehen und die darin fest eingebundenen Schussfadenenden wieder aus der Bindung zu lösen und so die Schussfadenenden sortenrein, vor dem aufzwirnenden Rotationskörper, als Abfall aufzunehmen.
Dieser dann sortenreine Schussfadenabfall kann durch weitere Aufbereitung in der Spinnerei wieder verwendet werden. In gleicher Weise ist dies zutreffend für den Fall, dass es sich um synthetische Schussfäden oder synthetische Dreherfäden handelt, die dann durch Einschmelzen zu einem sortenreinen Ausgangsmaterial geführt werden können.According to the invention the object is solved by the features of claims 1 and 8.
Thereafter, after the safety catch is separated from the fabric, the latter is fed to a rotary body which, at least in terms of its control, is connected to the drive of the rotary edge rotator, thereby twisting or unscrewing the full-twist binding of the safety catch.
Due to the synchronous or asynchronous running between the rotating body to be twisted on the catch strip and the rotary edge-turning device, it is possible for the first time to untwist the full-turn binding of a catch strip made by means of a rotary edge-turning device and to loosen the weft thread ends firmly integrated in the binding and thus the weft thread ends sorted by type, in front of the rotating body to be twisted as waste.
This weft thread waste, which is then sorted, can be reused by further processing in the spinning mill. In the same way, this applies to the case that synthetic weft threads or synthetic leno threads are involved, which can then be melted down to produce a pure starting material.

Je nach Verwendung von Schuss- und Dreherfadenmaterial kann eine erhebliche Kosteneinsparung pro Webmaschine und Jahr erzielt werden. Des weiteren entfällt dadurch die kostenaufwendige Entsorgung des Abfalls, was sich als ein erheblicher Beitrag zur positiven Umweltbeeinflussung darstellt.Depending on the use of weft and leno thread material, a significant one Cost savings can be achieved per weaving machine and year. Furthermore, this does not apply the costly disposal of the waste, which can make a significant contribution to represents positive environmental impact.

Die Erfindung soll nachstehenden anhand eines Ausführungsbeispieles näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment become.

Die Figur zeigt eine schematische Darstellung der erfindungsgemäßen Vorrichtung zum Erzeugen eines sortenreinen Schussfadenabfalls bei Verwendung von Spulen als Dreherfadenlieferer.The figure shows a schematic representation of the device according to the invention Generation of pure weft waste when using bobbins as Dreher yarn feeders.

In der Figur ist die linksseitig eines hergestellten Gewebes 2 vorhandene Vorrichtung zum Erzeugen von sortenreinem Schussfadenabfall aus Fangleisten 1 auf einer Webmaschine dargestellt. Die Webmaschine selbst ist hier nicht gezeigt, lediglich ansatzweise ist das auf der Webmaschine hergestellte und aus Schussfäden 3 und Kettfäden 10 bestehende Gewebe 2 zu sehen.
Wie an sich bekannt, werden auf schnell laufenden Webmaschinen zum Herstellen von festem und vom visuellen Eindruck her gediegenen Gewebekanten und zum Ausbilden von sogenannten Fangleisten 1 Rotations-Kantendreher 18 verwendet, wie sie unter anderem aus der vorgenannten DE 297 08 758 U1 bekannt sind. In the figure, the device on the left-hand side of a fabric 2 that has been produced for producing sorted weft thread waste from catch strips 1 is shown on a loom. The weaving machine itself is not shown here, only the fabric 2, which is produced on the weaving machine and consists of weft threads 3 and warp threads 10, can be seen.
As is known per se, on rotary weaving machines for the manufacture of firm and visually appealing fabric edges and for the formation of so-called catch strips 1 rotary edge rotators 18 are used, as are known, inter alia, from the aforementioned DE 297 08 758 U1.

Die erfindungsgemäße Lösung stellt nun darauf ab, dass die von Dreherfadenspulen 12 abgezogenen und zum Bilden einer eine Volldreherbindung aufweisende Fangleiste 1 verwendeten Dreherfäden 4 nach dem Abtrennen der Fangleiste 1 von dem Gewebe 2 mittels einer Schere 9 durch eine Aufdrehvorrichtung 5 derart bewegt werden, dass sich die Volldreherbindungen 1a auflösen und die dabei frei werdenden Enden 3a der Schussfäden 3 von einer aus einem Saugrohr 6a und aus wenigstens einem Sammelbehälter 6b bestehenden Abführeinrichtung 6 aufgenommen werden.
Wenn das Abführen oder das Sammeln der Schussfadenenden 3a in Abhängigkeit von einem dem Webprozess in der Webmaschinensteuerung zugrunde liegenden Schussfadenwahlprogramm vorgenommen wird, ist in weiterer Ausgestaltung der Erfindung die Abführeinrichtung 6 mit z.B. einem drehangetriebenen, mehrere Sammelbehälter 6b tragenden Drehteller ausgerüstet, der mittels eines elektromotorischen Antriebs 6c gemäß dem Schussfadenwahlprogramm den jeweiligen Sammelbehälter 6b der als Saugeinrichtung ausgebildeten Vorkehrung 6a zuordnet. Dies kann insbesondere beim Weben mehrfarbiger Gewebe mit verhältnismäßig breitem einfarbigen Schussfadenabschnitten von Vorteil sein. Zu diesem Zweck steht der Antrieb 6c über eine Steuerleitung 17 mit der Webmaschinensteuerung 8, in der das Schussfadenwahlprogramm abgelegt ist, signalübertragend in Verbindung.The solution according to the invention is now based on the fact that the leno threads 4 drawn from the leno thread bobbins 12 and used to form a catch strip 1 having a full-turn binding are moved after the catch strip 1 has been separated from the fabric 2 by means of a pair of scissors 9 by a twisting device 5 such that they move dissolve the full twist bindings 1a and the free ends 3a of the weft threads 3 are picked up by a discharge device 6 consisting of a suction pipe 6a and at least one collecting container 6b.
If the removal or collection of the weft thread ends 3a is carried out as a function of a weft thread selection program on which the weaving process is based in the weaving machine control system, in a further embodiment of the invention the discharge device 6 is equipped with, for example, a rotary table, which carries a plurality of collection containers 6b and which is operated by means of an electromotive drive 6c, according to the weft selection program, assigns the respective collecting container 6b to the arrangement 6a designed as a suction device. This can be of particular advantage when weaving multicolored fabrics with relatively wide single-colored weft sections. For this purpose, the drive 6c is connected via a control line 17 to the weaving machine control 8, in which the weft selection program is stored, in a signal-transmitting manner.

In weitere Ausgestaltung der Erfindung werden insbesondere die Verfahrensschritte Ausbilden einer Fangleisten-Volldreherbindung 1a, Abtrennen der Fangleiste 1 von dem Gewebe 2 mittels der Schere 9 und das Aufdrehen der Volldreherbindung 1a mittels der Aufdrehvorrichtung 5 durch die Ablaufsteuerung 8 elektrisch gesteuert ausgeführt.In a further embodiment of the invention, the method steps in particular Form a safety catch full-turn binding 1a, detach the safety catch 1 from the Fabric 2 using the scissors 9 and unscrewing the full twist binding 1a using the Unscrewing device 5 is electrically controlled by the sequence control 8.

Dabei kann das Aufdrehen der Volldreherbindungen 1 a synchron oder asynchron zu deren Herstellung durch den Rotations-Kantendreher 18 erfolgen. Wichtig ist dabei, dass bei asynchroner Betriebsweise und bei einer Betriebsweise mit Drehrichtungsumkehr die Anzahl der Vor- und Rückwärtsdrehungen der Rotationskörper 5a und 18a gleich groß ist. Dadurch ist sichergestellt, dass die Volldreherbindungen 1a immer im Bereich des Soges der Abführeinrichtung 6 aufgelöst werden.
Wenn also das Ausbilden der Volldreherbindungen 1a durch z.B. eine abwechselnde Drehrichtungsumkehr des in seiner Drehrichtung umkehrbaren Rotationskörpers 18a des Rotations-Kantendrehers 18 erfolgt, dann muss auch das Aufdrehen der Volldreherbindungen 1a zwangsläufig durch gesteuertes Umkehren der Drehrichtung des Rotationskörpers 5a der Aufdrehvorrichtung 5 erfolgen.
Die entsprechenden Steuerbefehle werden von der Ablaufsteuerung 8 über die Leitungen 15 und 16 signalübertragend dem Rotations-Kantendreher 18 bzw. der Aufdrehvorrichtung 5 erteilt.The full-turn bindings 1 a can be screwed on synchronously or asynchronously to their manufacture by the rotary edge driver 18. It is important that the number of forward and backward rotations of the rotary bodies 5a and 18a is the same in asynchronous mode of operation and in an operating mode with reversal of the direction of rotation. This ensures that the full-turn bindings 1a are always released in the area of the suction of the discharge device 6.
If the full-twist bindings 1a are thus formed by, for example, an alternating reversal of the direction of rotation of the rotational body 18a of the rotary edge rotator 18 which is reversible in its direction of rotation, then the full-twist bindings 1a must also be unscrewed by controlled reversal of the direction of rotation of the rotational body 5a of the unscrewing device 5.
The corresponding control commands are issued by the sequence control 8 via lines 15 and 16 in a signal-transmitting manner to the rotary edge rotator 18 or the unscrewing device 5.

Nach einem weiteren Verfahrensmerkmal werden die zum Ausbilden der Volldreherkante 1a verwendeten Dreherfäden 4 nach dem Auflösen der Volldreherbindungen 1a über eine Abziehvorrichtung 7 zu einem Sammelbehälter 14 geleitet.
Anstelle der als drehangetriebene Walze 7a und als Anpresswalze 7b dargestellten Abziehvorrichtung 7 und des Sammelbehälters 14 können die Dreherfäden 4 auf ein Paar von auf einem drehangetriebenen Spulenträger angeordneten drehangetriebenen Spulenkörper aufgespult und gegebenenfalls erneut als Dreherfäden verwendet werden.According to a further feature of the method, the leno threads 4 used to form the full leno selvedge 1a are passed to a collecting container 14 via a pulling device 7 after the loosening of the leno bindings 1a.
Instead of the pull-off device 7 and the collecting container 14, which is shown as a rotary roller 7a and a pressure roller 7b, the leno threads 4 can be wound onto a pair of rotary-driven bobbins arranged on a rotary bobbin and, if necessary, used again as leno threads.

Die erfindungsgemäße Vorrichtung zur Verfahrensdurchführung besteht aus der zuvor erwähnten Ablaufsteuerung 8, die einen an sich bekannten Rotations-Kantendreher 18 mit Rotationskörper 18a über die Steuerleitung 15 zum Ausbilden einer eine Volldreherkante 1a aufweisenden Fangleiste 1 ansteuert.
Der Rotationskörper 18a besitzt, wie an sich bekannt, Ösen 18b, durch die jeweils ein Dreherfaden 4 zu der zu bildenden Fangleiste 1 geführt ist. Der Rotationskörper 18a selbst muss in seiner Drehrichtung umkehrbar sein, weil die Dreherfäden 4 von ortsfest angeordneten Dreherfadenspulen 12 abgezogen werden.The device according to the invention for carrying out the method consists of the previously mentioned sequence control 8, which controls a known rotary edge rotator 18 with a rotating body 18a via the control line 15 to form a catch strip 1 having a full-turn edge 1a.
As is known per se, the rotating body 18a has eyelets 18b through which a leno thread 4 is guided to the catch bar 1 to be formed. The rotational body 18a itself must be reversible in its direction of rotation because the leno threads 4 are withdrawn from the leno bobbins 12 arranged in a stationary manner.

Ferner besteht die Vorrichtung aus einer in linearer Fortsetzung der Fangleiste 1 vorhandenen Vorrichtung 5 zum Aufdrehen der Volldreherbindung 1a, wobei der Antrieb 5b der Vorrichtung 5 über eine Steuerleitung 16 von der Steuerung 8 angesteuert wird.Furthermore, the device consists of an existing in linear continuation of the catch strip 1 Device 5 for unscrewing the full-turn binding 1a, the drive 5b being the Device 5 is controlled by the controller 8 via a control line 16.

Die Aufdrehvorrichtung 5 besitzt einen drehangetriebenen Rotationskörper 5a, der Ösen zum Hindurchführen der Dreherfäden 4 aufweist. The unscrewing device 5 has a rotationally driven rotating body 5a, the eyelets for Passing the leno threads 4.

Im vorliegenden Ausführungsbeispiel steht der Rotationskörper 5a mit dem Antrieb 5b über eine biegsame Welle 5c in Wirkverbindung.
Zwischen dem Rotations-Kantendreher 18 und der Aufdrehvorrichtung 5 ist nach der Fangleiste 1, die von dem Gewebe 2 mittels der Schere 14 abgetrennt ist, die Abführeinrichtung 6 für die Schussfadenenden 3a derart eingeordnet, dass eine Vorkehrung 6a in Gestalt eines Saugrohres die Schussfadenenden 3a nach dem Auflösen der Volldreherbindung 1a absaugt und in wenigstens einen als Mittel 6b ausgebildeten Sammelbehälter fördert.In the present exemplary embodiment, the rotating body 5a is operatively connected to the drive 5b via a flexible shaft 5c.
Between the rotary edge-turning device 18 and the unscrewing device 5, after the catch bar 1, which is separated from the fabric 2 by means of the scissors 14, the removal device 6 for the weft thread ends 3a is arranged in such a way that a provision 6a in the form of a suction pipe follows the weft thread ends 3a the dissolving of the full-twist binding sucks off and conveys into at least one collecting container designed as means 6b.

Die Abführeinrichtung 6 besitzt mehrere auf einem drehangetriebenen Drehteller montierte Sammelbehälter 6b, wobei wie im Verfahrensablauf bereits dargelegt, das sortenreine Sammeln der Schussfadenenden 3a steuerungstechnisch in Abhängigkeit von einem dem Webprozess in der hier nicht gesondert dargestellten Webmaschinensteuerung zugrunde liegenden Schussfadenwahlprogramm vorgenommen wird.
Mit anderen Worten ausgedrückt, ein erster Sammelbehälter wird alle Schussfadenenden einer ersten Schussfarbe aufnehmen, ein zweiter Sammelbehälter wird als Schussfadenenden einer zweiten Schussfarbe aufnehmen und ein dritter Sammelbehälter wird alle Schussfadenenden einer dritten Schussfarbe aufnehmen.
Entsprechend der durch das Schussfadenwahlprogramm in ein Webfach einzutragenden Schussfarben wird der Drehantrieb 6c über die Leitung 17 von der Ablaufsteuerung 8 dementsprechend angesteuert.The discharge device 6 has a plurality of collecting containers 6b mounted on a rotary-driven turntable, whereby, as already explained in the process sequence, the sorted collection of the weft thread ends 3a is carried out in terms of control technology as a function of a weft selection program on which the weaving process control is based, which is not shown separately here.
In other words, a first collecting container will hold all weft ends of a first weft color, a second collecting container will hold all weft ends of a third weft color and a third collecting container will hold all weft ends of a third weft color.
Corresponding to the weft colors to be entered into a shed by the weft selection program, the rotary drive 6c is controlled accordingly by the sequence control 8 via the line 17.

Mit der erfindungsgemäßen technischen Lehre ist es erstmals möglich, die in einer Volldreherkante fest eingebundenen Schussfäden einer Fangleiste bindungsmäßig wieder zu lösen und diese sortenrein nach dem Aufdrehen als sortenreinen Abfall zu sammeln. Die Dreherfäden können entweder als sortenreiner Abfall gesammelt oder durch auf einem drehangetriebenen Spulenträger angeordnete Spulenkörper aufgewickelt und erneut als Dreherfäden verwendet werden. With the technical teaching according to the invention, it is possible for the first time in a The fully twisted edge of firmly integrated weft threads binds back to a catch strip solve and collect them sorted after sorting as sorted waste. The Turner threads can either be collected as sorted waste or through on one rotatably driven bobbin arranged wound bobbin and again as Leno threads are used.
