Description

Die vorliegende Erfindung betrifft eine Litzensepariervorrichtung für Kettfadeneinziehmaschinen, mit Tragschienen zum Speichern der Litzen in Form eines Stapels, mit einem Abteilorgan zum seitlichen Herausschieben der jeweils vordersten Litze aus dem Stapel in eine Zwischenposition und mit einem ersten Uebergabemittel zum Transport der Litzen von der Zwischenposition in Richtung auf einen Litzenträger für den Transport der Litzen an ihre Einzugsposition.The present invention relates to a heald separating device for warp threading machines, with support rails for storing the healds in the form of a stack, with a compartment member for laterally pushing the foremost heald from the stack into an intermediate position and with a first transfer means for transporting the healds from the intermediate position in the direction on a heald carrier for transporting the healds to their retracted position.

Bei einer in der EP-A-0 448 957 (= US-A-5,184,380) beschriebenen Vorrichtung dieser Art für die Separierung von Litzen mit offenen Endösen sind die Tragschienen seitlich an Tragarmen befestigt, wobei die Verbindung zwischen den Tragschienen und Tragarmen im Bereich des offenen Teils der Endösen erfolgt, so dass die Verschiebung der Sitzen auf den Tragschienen durch die Tragarme nicht behindert ist. Da zur Ermöglichung einer störungsfreien Uebergabe der separierten Litzen an den Litzenträger die Tragschienen möglichst nahe am Litzenträger fixiert sein müssen, ist klar, dass diese bekannte Vorrichtung für die Separierung von Litzen mit geschlossenen Endösen nicht geeignet ist. Denn die die Tragschienen allseitig umfassenden geschlossenen Endösen könnten die die Tragschienen fixierenden Tragarme nicht passieren.In a device of this type described in EP-A-0 448 957 (= US-A-5,184,380) for the separation of strands with open end loops, the mounting rails are attached laterally to mounting arms, the connection between the mounting rails and mounting arms in the area of open part of the end eyelets, so that the displacement of the seats on the mounting rails is not hindered by the mounting arms. Since the carrier rails must be fixed as close as possible to the heald carrier in order to enable the separated healds to be transferred to the heald carrier without interference, it is clear that this known device is not suitable for separating healds with closed end loops. Because the closed end loops encompassing the mounting rails on all sides could not pass through the mounting arms fixing the mounting rails.

Eine für die Separierung von Litzen mit geschlossenen Endösen geeignete Vorrichtung ist von der Einziehanlage USTER EMU (USTER - eingetragenes Warenzeichen der Zellweger Uster AG) her bekannt. Bei dieser Vorrichtung sind die Tragschienen nur an einem Ende eingespannt und ragen mit ihrem freien Ende bis zu einer Uebergabestation, an der die Uebergabe an die Litzentragschienen der Webschäfte erfolgt. Hier werden spezielle Litzen verwendet, die eine den Eingriff eines Separiermessers ermöglichende Prägung aufweisen. Die separierten Litzen werden dann von einem Transportorgan über die freien Enden der Tragschienen in die Uebergabestation geschoben.A suitable device for the separation of strands with closed end loops is the USTER EMU (USTER - Registered trademark of Zellweger Uster AG). In this device, the support rails are clamped at only one end and project with their free end to a transfer station, at which the transfer to the heddle support rails of the heald frames takes place. Special strands are used here, which have an embossing that enables the intervention of a separating knife. The separated strands are then pushed by a transport element over the free ends of the mounting rails into the transfer station.

Diese Vorrichtung verwendet Tragschienen von sehr geringer Länge und ist daher für automatische Einziehmaschinen nicht geeignet. Denn es muss in sehr kurzen Abständen eine leere gegen eine volle Tragschiene gewechselt werden, was immer einen unerwünschten Stop der Einziehmaschine bedeutet. Ausserdem stellen die nur einseitig eingespannten Tragschienen eine erhebliche potentielle Störungsquelle dar, insbesondere bei höheren Separierfrequenzen, wie sie heute von einer automatischen Einziehmaschine verlangt werden.This device uses mounting rails of very short length and is therefore not suitable for automatic drawing machines. Because an empty carrier rail must be exchanged for a full carrier rail at very short intervals, which always means an unwanted stop of the drawing-in machine. In addition, the mounting rails, which are only clamped on one side, represent a considerable potential source of interference, especially at higher separation frequencies, as are required today by an automatic drawing-in machine.

Durch die Erfindung soll nun eine Separiervorrichtung der eingangs genannten Art angegeben werden, die eine störungsfreie Separierung von Litzen mit geschlossenen Endösen ermöglicht.The invention is now to provide a separating device of the type mentioned at the outset which enables trouble-free separation of strands with closed end loops.

Gemäss Fig. 1 besteht die Einziehmaschine aus einem Grundgestell 1 und aus verschiedenen in diesem angeordneten Baugruppen, welche jede ein Funktionsmodul bilden. Vor dem Grundgestell 1 ist ein Kettbaumwagen 2 mit einem auf diesem angeordneten Kettbaum 3 zu erkennen. Der Kettbaumwagen 2 enthält ausserdem eine Hebevorrichtung 4 zur Halterung eines Fadenrahmens 5, auf welchem die Kettfäden KF aufgespannt sind. Dieses Aufspannen erfolgt vor dem eigentlichen Einziehen und an einem von der Einziehmaschine getrennten Ort, wobei der Fadenrahmen 5 am unteren Ende der Hebevorrichtung 4 in unmittelbarer Nähe zum Kettbaum 3 positioniert ist. Für das Einziehen wird der Kettbaumwagen 2 mit Kettbaum 3 und Hebevorrichtung 4 an die sogenannte Aufrüstseite der Einziehmaschine gefahren und der Fadenrahmen 5 wird von der Hebevorrichtung 4 nach oben gehoben und in das Grundgestell 1 eingehängt, wo er dann die dargestellte Lage einnimmt.1, the drawing-in machine consists of a base frame 1 and of various assemblies arranged in it, each of which forms a functional module. In front of the base frame 1, a warp beam carriage 2 with a warp beam 3 arranged on it can be seen. The warp beam carriage 2 also contains a lifting device 4 for holding a thread frame 5 on which the warp threads KF are stretched. This tensioning takes place before the actual pulling-in and at a location separate from the drawing-in machine, the thread frame 5 being positioned at the lower end of the lifting device 4 in the immediate vicinity of the warp beam 3. For pulling in, the warp beam carriage 2 with the warp beam 3 and lifting device 4 is moved to the so-called upgrade side of the pulling-in machine and the thread frame 5 is lifted up by the lifting device 4 and suspended in the base frame 1, where it then assumes the position shown.

Der Fadenrahmen 5 ist durch einen nicht dargestellten Antrieb in Längsrichtung des Grundgestells 1 verschiebbar. Bei dieser Verschiebung werden die Kettfäden KF an einer Teil eines sogenannten Garnmoduls bildenden Fadentrenngruppe 6 vorbeigeführt und dabei separiert und abgeteilt. Nach dem Abteilen werden die Kettfäden KF abgeschnitten und einer Einziehnadel 7 präsentiert, welche Bestandteil des sogenannten Einzugsmoduls bildet. Für das Abteilen der Kettfäden kann beispielsweise die in der Webkettenknüpfmaschine USTER TOPMATIC verwendete Abteileinrichtung eingesetzt werden.The thread frame 5 is displaceable in the longitudinal direction of the base frame 1 by a drive, not shown. With this shifting, the warp threads KF are guided past a thread separation group 6 forming part of a so-called yarn module, and are separated and divided in the process. After division, the warp threads KF are cut off and presented to a pull-in needle 7, which forms part of the so-called pull-in module. For the division of the warp threads, for example, that in the warp knitting machine USTER TOPMATIC used compartment equipment can be used.

Neben der Einziehnadel 7 ist ein Bildschirmgerät 8 zu erkennen, welches zu einer Bedienungsstation gehört und zur Anzeige von Maschinenfunktionen und Maschinenfehlfunktionen und zur Dateneingabe dient. Die Bedienungsstation, die Teil eines sogenannten Programmiermoduls bildet, enthält auch eine Eingabestufe für die manuelle Eingabe gewisser Funktionen, wie beispielsweise Kriechgang, Start/Stop, Repetition von Vorgängen, und dergleichen. Die Steuerung der Einziehmaschine erfolgt durch ein einen Steuerrechner enthaltendes Steuermodul, welches in einem Steuerkasten 9 angeordnet ist. Dieser Steuerkasten enthält neben dem Steuerrechner für jedes sogenannte Hauptmodul einen Modulrechner, wobei die einzelnen Modulrechner vom Steuerrechner gesteuert und überwacht sind. Die Hauptmodule der Einziehmaschine sind neben den schon erwähnten Modulen Einzugsmodul, Garnmodul, Steuermodul und Programmiermodul, noch das Litzen-, das Lamellen- und das Blattmodul.In addition to the pull-in needle 7, a monitor 8 can be seen, which belongs to an operating station and is used to display machine functions and machine malfunctions and for data input. The operating station, which forms part of a so-called programming module, also contains an input stage for the manual input of certain functions, such as, for example, crawl gear, start / stop, repetition of operations, and the like. The drawing-in machine is controlled by a control module containing a control computer, which is arranged in a control box 9. In addition to the control computer, this control box contains a module computer for each so-called main module, the individual module computers being controlled and monitored by the control computer. The main modules of the drawing machine are, in addition to the modules already mentioned, drawing module, yarn module, control module and programming module, the strand, the lamella and the sheet module.

Die Fadentrenngruppe 6, welche der Einziehnadel 7 die einzuziehenden Kettfäden KF präsentiert, und die Bewegungsbahn der Einziehnadel 7, welche vertikal zur Ebene der aufgespannten Kettfäden KF verläuft, bestimmen eine Ebene im Bereich einer Teil des Grundgestells bildenden Stütze 10, welche die schon erwähnte Aufrüstseite von der sogenannten Abrüstseite der Einziehmaschine trennt. An der Aufrüstseite werden die Kettfäden und die einzelnen Elemente, in welche die Kettfäden einzuziehen sind, zugeführt, und an der Abrüstseite kann das sogenannte Geschirr (Litzen, Lamellen und Blatt) mit den eingezogenen Kettfäden entnommen werden. Während des Einziehens werden der Fadenrahmen 5 mit mit den Kettfäden KF und der Kettbaumwagen 2 mit dem Kettbaum 3 an der Fadentrenngruppe 6 vorbei nach rechts bewegt, wobei die Einziehnadel 7 dem Rahmen 5 nacheinander die auf diesem aufgespannten Kettfäden KF entnimmt.The thread separation group 6, which presents the warp threads KF to be drawn in to the pull-in needle 7, and the path of movement of the pull-in needle 7, which runs vertically to the plane of the stretched warp threads KF, determine a plane in the region of a support 10 forming part of the base frame, which supports the already mentioned upgrade side of the so-called disassembly side of the drawing machine. The warp threads and the individual elements into which the warp threads are to be fed are fed in on the upgrade side, and the so-called dishes (strands, Slats and leaf) can be removed with the warp threads drawn in. During the pulling-in, the thread frame 5 with the warp threads KF and the warp beam carriage 2 with the warp beam 3 are moved past the thread separating group 6 to the right, the pull-in needle 7 successively removing the warp threads KF stretched on the frame 5.

Wenn alle Kettfäden KF eingezogen sind und der Fadenrahmen 5 leer ist, befindet sich der letztere zusammen mit dem Kettbaumwagen 2, dem Kettbaum 3 und der Hebevorrichtung 4 auf der Abrüstseite und kann vom Grundgestell 1 abgenommen werden.When all the warp threads KF have been drawn in and the thread frame 5 is empty, the latter is together with the warp beam carriage 2, the warp beam 3 and the lifting device 4 on the dismantling side and can be removed from the base frame 1.

Unmittelbar hinter der Ebene der Kettfäden KF sind die Kettfadenwächterlamellen LA angeordnet, hinter diesen die Weblitzen LI und noch weiter hinten das Webblatt. Die Lamellen LA werden in Handmagazinen gestapelt, und die vollen Handmagazine werden in geneigt angeordnete Zuführschienen 11 gehängt, auf denen sie nach rechts, zur Einziehnadel 7 hin, transportiert werden. Dort werden sie separiert und in die Einzugsposition gebracht. Nach erfolgtem Einzug gelangen die Lamellen LA auf Lamellentragschienen 12 auf der Abrüstseite.Immediately behind the plane of the warp threads KF are the warp thread guard slats LA, behind them the healds LI and even further behind the reed. The lamellae LA are stacked in hand magazines, and the full hand magazines are hung in inclined feed rails 11, on which they are transported to the right, towards the pull-in needle 7. There they are separated and brought into the feed position. After pulling in, the slats LA arrive on slat support rails 12 on the dismantling side.

Die Litzen LI werden auf Schienen 13 aufgereiht und auf diesen manuell oder automatisch zu einer Separierstufe verschoben. Dann werden die Litzen LI einzeln in ihre Einziehposition gebracht und nach erfolgtem Einzug auf die entsprechenden Tragschienen 14 auf der Abrüstseite verteilt. Das Webblatt wird ebenfalls schrittweise an der Einziehnadel 7 vorbeibewegt, wobei die entsprechende Blattlücke für den Einzug geöffnet wird. Nach dem Einzug befindet sich das Blatt ebenfalls auf der Abrüstseite. Rechts neben den Tragschienen 14 ist ein Teil des Webblatt WB zu erkennen. Dieses Darstellung ist rein illustrativ zu verstehen, weil sich das Webblatt bei der dargestellten Position des Rahmens 5 selbstverständlich auf der Aufrüstseite befindet.The strands LI are lined up on rails 13 and manually or automatically shifted to a separation stage on them. Then the strands LI are individually brought into their retracted position and, after they have been drawn in, distributed to the corresponding mounting rails 14 on the dismantling side. The reed is also moved past the pull-in needle 7 step by step, the corresponding sheet gap being opened for the feed. After this The sheet is also on the disassembly side. A part of the reed WB can be seen to the right of the mounting rails 14. This illustration is to be understood purely for illustrative purposes, since the reed is of course located on the upgrade page in the position of the frame 5 shown.

Wie der Figur weiter entnommen werden kann, ist auf der Abrüstseite ein sogenannter Geschirrwagen 15 vorgesehen. Dieser wird zusammen mit den darauf befestigten Lamellentragschienen 12, den Tragschienen 14 und einer Halterung für das Webblatt in das Grundgestell 1 in die dargestellte Position eingeschoben und trägt nach dem Einziehen das Geschirr mit den eingezogenen Kettfäden KF. Zu diesem Zeitpunkt befindet sich der Kettbaumwagen 2 mit dem Kettbaum 3 unmittelbar vor dem Geschirrwagen 15. Nun wird mittels der Hebevorrichtung 4 das Geschirr vom Geschirrwagen 15 auf den Kettbaumwagen 2 umgeladen, der dann den Kettbaum 3 und das eingezogene Geschirr trägt und an die betreffende Webmaschine oder in ein Zwischenlager gefahren werden kann.As can be seen from the figure, a so-called table wagon 15 is provided on the dismantling side. This is inserted together with the slat support rails 12 fastened thereon, the support rails 14 and a holder for the reed into the base frame 1 in the position shown and, after being pulled in, carries the dishes with the warp threads KF drawn in. At this point in time, the warp beam carriage 2 with the warp beam 3 is located directly in front of the dishwashing carriage 15. Now the dishes are reloaded from the dishwashing carriage 15 onto the warp beam carriage 2 by means of the lifting device 4, which then carries the warp beam 3 and the drawn-in dishes and to the relevant weaving machine or can be moved to an interim storage facility.

Die beschriebenen Funktionen sind auf mehrere Module verteilt, welche praktisch autonome Maschinen darstellen, die vom gemeinsamen Steuerrechner gesteuert sind. Die Querverbindungen zwischen den einzelnen Modulen laufen über diesen übergeordneten Steuerrechner und es existieren keine direkten Querverbindungen zwischen den einzelnen Modulen. Die schon genannten Hauptmodule der Einziehmaschine sind selbst wieder modular aufgebaut und bestehen in der Regel aus Teilmodulen.The functions described are distributed over several modules, which represent practically autonomous machines that are controlled by the common control computer. The cross-connections between the individual modules run via this higher-level control computer and there are no direct cross-connections between the individual modules. The main modules of the drawing-in machine which have already been mentioned are themselves modular again and generally consist of sub-modules.

Dieser modulare Aufbau, der in der CH-A-579 871 beschrieben ist, ist aus der Darstellung von Fig. 2 besonders gut ersichtlich. Man erkennt in Fig. 2 das Grundgestell 1, den Kettbaumwagen 2 mit dem Kettbaum 3, die Hebevorrichtung 4 und den Fadenrahmen 5, die mit dem Kettbaumwagen 2 zusammengekoppelt sind, das Garnmodul, das Lamellenmodul, das Litzenmodul, das Blattmodul, die Bedienungsstation mit dem Bildschirm 8, das Einzugsmodul, den Steuerkasten 9, das Teilmodul Litzenmagazinierung, das Teilmodul Lamellenmagazinierung, und den Geschirrwagen 15 mit den Lamellentragschienen 12 und den Tragschienen 14.This modular structure, which is described in CH-A-579 871, can be seen particularly well from the illustration in FIG. 2. 2 shows the base frame 1, the warp beam carriage 2 with the warp beam 3, the lifting device 4 and the thread frame 5, which are coupled together with the warp beam carriage 2, the yarn module, the slat module, the heddle module, the sheet module, the operating station with the Screen 8, the feed module, the control box 9, the sub-module stranded wire magazine, the sub-module lamellaed magazine, and the crockery trolley 15 with the lamellar support rails 12 and the support rails 14.

Wie der schon genannten CH-A-679 871 zu entnehmen ist, besteht das Litzenmodul, das die Litzen LI vom Magazinstapel bis zu der einen eingezogenen Kettfaden tragenden Litze auf einer Tragschiene 14 abarbeitet, aus folgenden Teilmodulen:

  • Litzenmagazin: Entgegennahme der Litzen vom Anwender ab Stapel, Weitergabe der Litzenstapel an das Teilmodul "Litzenseparierung".
  • Litzenseparierung: Aufnahme der Litzenstapel, Separierung der Litzen vom Stapel, Weitergabe der separierten Litzen an das Teilmodul "Litzenpositionierung".
  • Litzenpositionierung: Uebernahme der Litzen vom Teilmodul "Litzenseparierung", Transport der Litzen zur Einzugsposition, seitliche und vertikale Positionierung der Litzen, Transport der Litzen mit dem eingezogenen Kettfaden zur vorbestimmten Tragschienenposition, Uebergabe der Litzen an die jeweilige Tragschiene.
  • Litzenförderung: Förderung der Litzen mit den eingezogenen Kettfäden entlang der Tragschienen von der Auffüllseite an das andere Ende.
As can be seen from the already mentioned CH-A-679 871, the strand module, which processes the strands LI from the magazine stack to the strand carrying a drawn-in warp thread on a mounting rail 14, consists of the following sub-modules:
  • Strand magazine: acceptance of the strands by the user from the stack, transfer of the strand stacks to the sub-module "strand separation".
  • Strand separation: picking up the strand stacks, separating the strands from the stack, passing on the separated strands to the sub-module "strand positioning".
  • Strand positioning: transfer of the strands from the "strand separation" sub-module, transport of the strands to the retracted position, lateral and vertical positioning of the strands, transport of the strands with the drawn-in warp thread to the predetermined mounting rail position, transfer of the strands to the respective mounting rail.
  • Strand conveying: conveying the strands with the drawn-in warp threads along the mounting rails from the filling side to the other end.

Das Teilmodul "Litzenseparierung" für die Abarbeitung von Litzen mit offenen Endösen ist in der US-A-5,184,380 beschrieben, das Teilmodul "Litzenpositionierung" in der EP-A-0 500 848 (= WO-A-92/05303). Nachfolgend soll nun zuerst das Teilmodul "Litzenmagazin" und anschliessend das Teilmodul "Litzenseparierung" beschrieben werden, und zwar jeweils für die Abarbeitung von Litzen mit geschlossenen Endösen.The sub-module "strand separation" for the processing of strands with open end loops is described in US-A-5,184,380, the sub-module "strand positioning" in EP-A-0 500 848 (= WO-A-92/05303). In the following, the sub-module "strand magazine" and then the sub-module "strand separation" will now be described, in each case for the processing of strands with closed end loops.

Wie Fig. 3 zu entnehmen ist, besteht das Litzenmagazin im wesentlichen aus einer unteren und einer oberen Profilschiene 16 bzw. 17, in der die Litzentragschienen 13 und Mittel für die Förderung der auf den Tragschienen aufgereihten Litzen zur Separierstation gelagert sind. Die in der Figur mit ST bezeichnete Separierstation schliesst unmittelbar an die Litzentragschienen 13 an, wobei die Separierstation ST pro Litzentragschiene 13 jeweils eine obere und eine untere Separierstufe mit einem quer zum Litzenstapel bewegbaren Separiermesser 18 und einen oder zwei Uebergeber 19 aufweist. Ausserdem ist für beide Separierstufen ein gemeinsamer Trennfinger 20 vorgesehen. Alle diese Organe sind in der US-A-5,184,380, auf deren Offenbarung hiermit ausdrücklich Bezug genommen wird, ausführlich beschrieben.As can be seen in FIG. 3, the heddle magazine essentially consists of a lower and an upper profile rail 16 or 17, in which the heddle support rails 13 and means for conveying the strands lined up on the support rails are stored to the separation station. The separating station designated ST in the figure connects directly to the heddle support rails 13, the separating station ST having an upper and a lower separation stage for each heddle support rail 13, with a separating knife 18 which can be moved transversely to the strand stack and one or two transmitters 19. In addition, a common separation finger 20 is provided for both separation stages. All of these organs are described in detail in US-A-5,184,380, the disclosure of which is incorporated herein by reference.

Darstellungsgemäss ist das Litzenmagazin zweipfadig ausgebildet und enthält zwei Paare von Litzentragschienen 13 und von Separierstufen. An der separierstufenseitigen Stirnseite der Profilschienen 16 und 17 ist je eine massive Platte 21 befestigt, die zwei stirnseitig wegragende Zapfen 22 trägt. Diese Zapfen dienen als Schnittstelle zum Teilmodul "Litzenpositionierung" und sind zum Eingriff und zur Fixierung in entsprechenden Ausnehmungen dieses Teilmoduls vorgesehen.According to the illustration, the heddle magazine is configured in two paths and contains two pairs of heddle support rails 13 and of separation stages. On the separator side of the profile rails 16 and 17, a solid plate 21 is attached, which carries two pins 22 projecting at the end. These pins serve as an interface to the sub-module "strand positioning" and are provided for engagement and fixing in corresponding recesses of this sub-module.

Die beiden Profilschienen 16 und 17 sind auf einem auf einem schienengeführten Verschiebewagen 23 montierten Träger 24 höhenverstellbar befestigt. Mit einer Kurbel 25 ist die Distanz der Endösen der Litzen einstellbar; der Versatz der Fadenaugen ist ebenfalls einstellbar. Mit dem Bezugszeichen 26 ist ein Gehäuse mit der Elektrik und Elektronik bezeichnet und mit dem Bezugszeichen 27 ein Gehäuse für die Pneumatiksteuerung. Beide Gehäuse sind über entsprechende Leitungen mit dem Verschiebewagen 23 verbunden, der seinerseits an entsprechende Versorgungs- und Datenleitungen der Einziehmaschine angeschlossen und dadurch insbesondere auch mit dem Steuermodul im Steuerkasten 9 (Fig. 1, 2) verbunden ist.The two profile rails 16 and 17 are fastened in a height-adjustable manner on a support 24 mounted on a rail-guided sliding carriage 23. The distance between the end loops of the strands is adjustable with a crank 25; the offset of the thread eyes is also adjustable. Reference number 26 denotes a housing with the electrics and electronics and reference number 27 denotes a housing for the pneumatic control. Both housings are connected via corresponding lines to the sliding carriage 23, which in turn is connected to the corresponding supply and data lines of the drawing-in machine and is therefore in particular also connected to the control module in the control box 9 (FIGS. 1, 2).

Auf jeder Profilschiene 16, 17 sind zwei Litzentragschienen 13 gehalten, die sich von dem in Fig. 3 rechten Ende der Profilschienen, das ist die Beschickungsseite des Litzenmagazins, bis zur Separierstation ST erstrecken und die eine Länge von über zwei Metern aufweisen. Die zu magazinierenden Litzen werden auf sogenannte Transferschienen (nicht dargestellt) aufgereiht, das ist ein Paar von Schienen, die an ihrem einen Ende durch einen Steg miteinander verbunden sind und von diesem Steg frei nach vorne ragen. Der Steg dient nicht nur als Träger der Transferschienen, sondern ist auch eine Art von Griff zu deren Handhabung. Zur Füllung des Litzenmagazins werden die Transferschienen mit den darauf befindlichen Litzen mittels Klemmen an die beschickungsseitigen Enden der Litzentragschienen 13 angedockt und auf die Litzentragschienen geschoben.On each profile rail 16, 17, two heald support rails 13 are held, which extend from the right end of the profile rails in FIG. 3, that is the loading side of the heald magazine, to the separating station ST and which have a length of over two meters. The strands to be stacked are lined up on so-called transfer rails (not shown), that is a pair of rails which are connected to one another by a web at one end and project freely from this web. The web not only serves as a carrier for the transfer rails, but is also a type of handle for handling them. To fill the heald magazine, the transfer rails with the healds located thereon are docked onto the ends of the heald support rails 13 on the loading side and pushed onto the heald support rails.

Nach einer relativ kurzen Verschiebung von Hand gelangen die Litzen in den Wirkungsbereich eines Transportmittels, welches die Litzen in Richtung des Pfeiles A gegen die Separierstation ST fördert. Dieses Transportmittel ist durch einen mit seitlich abstehenden, die Litzen kontaktierenden Bürsten 28 bestückten Förderriemen 29 gebildet, wobei entlang jeder Litzentragschiene 13 ein derartiger Förderriemen 29 angeordnet ist. Jedes einem Pfad des Litzenmagazins zugeordnete Paar von Förderriemen 29 ist durch einen eigenen Motor 30 angetrieben. Kurz vor der Separierstation ST ist seitlich neben jeder Litzentragschiene 13 eine motorisch angetriebene Anpressbürste 31 angeordnet, die die Litzen gegen die jeweilige Separierstufe fördert und für einen konstanten Staudruck in der Separierstation ST sorgt.After a relatively short shift by hand, the strands come into the effective range of a means of transport which conveys the strands in the direction of arrow A against the separating station ST. This means of transport is formed by a conveyor belt 29 equipped with laterally projecting brushes 28 contacting the strands, such a conveyor belt 29 being arranged along each strand support rail 13. Each pair of conveyor belts 29 assigned to a path of the heddle magazine is driven by its own motor 30. Shortly before the separation station ST, a motor-driven pressure brush 31 is arranged on the side next to each heald support rail 13, which presses the healds against the respective separation stage and ensures a constant dynamic pressure in the separation station ST.

Das in Fig. 3 dargestellte Litzenmagazin ist universell verwendbar und für die Magazinierung von Litzen mit offenen und von solchen mit geschlossenen Endösen geeignet. Litzen mit offenen Endösen können problemlos magaziniert werden, weil sie hakenartige Endösen haben und daher ohne Mühe auf den Tragschienen verschoben werden können, wenn nur die die Tragschienen haltenden Träger im Bereich des offenen Teils der Endösen, das ist das Maul des Hakens, liegen. Litzen mit geschlossenen Endösen hingegen können nur auf rundum freien Tragschienen verschoben werden, was aber bei Tragschienen mit einer Länge von mehr als einem halben Meter nicht realisiert werden kann. Beim dargestellten Litzenmagazin wird die Verschiebbarkeit von Litzen mit geschlossenen Endösen auf den Litzentragschienen 13 dadurch ermöglicht, dass jede Litzentragschiene 13 durch mehrere gesteuerte Klemmen K₁ bis K₆ gehalten und dadurch der Transportweg der Litzen auf den Tragschienen in mehrere Sektionen zur Aufnahme je eines Litzenpakets unterteilt ist. Der Transport der Litzen erfolgt paketweise von Sektion zu Sektion, wobei bei der Verschiebung von einer Sektion zur nächsten jeweils die zwischen diesen Sektionen liegende Klemme geöffnet ist.The heddle magazine shown in FIG. 3 can be used universally and is suitable for the storage of heddles with open and those with closed end loops. Stranded wires with open end loops can be easily stored because they have hook-like end loops and can therefore be easily moved on the mounting rails if only the carriers holding the mounting rails lie in the area of the open part of the end loops, i.e. the mouth of the hook. Stranded wires with closed end loops, on the other hand, can only be moved on all-round free mounting rails, but this is the case with mounting rails with a length of more than one half a meter cannot be realized. In the illustrated heald magazine, the displaceability of healds with closed end eyelets on the heald support rails 13 is made possible by the fact that each heald support rail 13 is held by several controlled clamps K₁ to K₆ and the transport path of the healds on the support rails is divided into several sections for receiving a strand package in each case. The strands are transported in packages from section to section, whereby the clamp between these sections is opened when moving from one section to the next.

Das Oeffnen und Schliessen der Klemmen K₁ bis K₆ ist so gesteuert, dass zwei nebeneinander liegende Klemmen niemals gleichzeitig geöffnet sein können. Zur Steuerung der Klemmen sind in deren unmittelbarer Nachbarschaft Detektoren 32 (Fig. 7a, 7b) für den Durchgang von Litzen angeordnet. Wenn das Litzenmagazin leer ist und der erste Litzenstapel von den Transferschienen auf die Litzentragschienen 13 geschoben wird, stellt der an der ersten Klemme K₁ angeordnete Detektor 32 das Vorhandensein dieses Litzenstapels an der ersten Klemme fest und öffnet diese. Der Litzenstapel kann somit die erste Klemme passieren, gelangt in den Wirkungsbereich des mit den Bürsten 28 bestückten Förderriemens 29 und wird von diesem automatisch zur zweiten Klemme K₂ geschoben.The opening and closing of the terminals K₁ to K₆ is controlled so that two adjacent terminals can never be open at the same time. To control the terminals, detectors 32 (FIGS. 7a, 7b) for the passage of strands are arranged in their immediate vicinity. When the heald magazine is empty and the first heald stack is pushed from the transfer rails onto the heald support rails 13, the detector 32 arranged on the first clamp K 1 detects the presence of this heald stack on the first clamp and opens it. The strand of strands can thus pass the first clamp, comes into the effective range of the conveyor belt 29 equipped with the brushes 28 and is automatically pushed by this to the second clamp K₂.

Nach einer bestimmten, einstellbaren Zeitspanne von beispielsweise 9 Sekunden wird die erste Klemme K₁ geschlossen und es beginnt der automatische Transport des Litzenstapels zur Separierstation ST, der schrittweise von Klemme zu Klemme erfolgt. Sobald die Klemme K₁ wieder geschlossen ist und der Detektor 32 an der Klemme K₂ das Vorhandensein von Litzen feststellt, wird die Klemme K₂ geöffnet und zwar so lange, bis deren Detektor keine Litzen mehr detektiert. Dann wird die Klemme K₃ geöffnet, und so weiter. Sobald die Sektion zwischen den Klemmen K₁ und K₂ leer und die Klemme K₂ wieder geschlossen ist, kann ein neuer Litzenstapel von den Transferschienen übergeben werden. Beim Transport eines Litzenstapels durch das nicht vollständig leere sondern mindestens teilweise gefüllte Litzenmagazin ist das Oeffnen einer Klemme von einem weiteren Kriterium abhängig, und zwar davon, ob die an die zu öffnende Klemme anschliessende Sektion leer ist. Ob dieses Kriterium erfüllt ist, wird anhand des Signals des Detektors an der die genannte Sektion in Transportrichtung A abschliessenden Klemme festgestellt: Hat dieser Detektor das vollständige Passieren des vorherigen Litzenstapels registriert, dann ist die betreffende Sektion leer. Die Signale der einzelnen Detektoren werden in einer gemeinsamen Steuerung im Gehäuse 26 verarbeitet, wobei die Steuerung aufgrund des paketweisen Transports der Litzenstapel von Sektion zu Sektion immer "weiss", in welcher Sektion sich ein bestimmter Litzenstapel gerade befindet und welche Sektionen leer und welche voll sind. Auf diese Weise sind Stauungen in den Sektionen oder eine Ueberfüllung von diesen ausgeschlossen.After a certain, adjustable period of time, for example 9 seconds, the first clamp K 1 is closed and the automatic transport of the strand stack to the separation station ST begins, which takes place step by step from clamp to clamp. As soon as the clamp K 1 is closed again and the detector 32 detects the presence of strands at the clamp K 2, the clamp K 2 is opened until the detector no longer detects strands. Then the clamp K₃ is opened, and so on. As soon as the section between the terminals K₁ and K₂ is empty and the terminal K₂ is closed again, a new strand of strands can be transferred from the transfer rails. When a strand stack is transported through the strand magazine, which is not completely empty but at least partially filled, the opening of a clamp is dependent on a further criterion, namely whether the section adjoining the clamp to be opened is empty. Whether this criterion is met is determined on the basis of the signal from the detector at the terminal terminating the section mentioned in transport direction A: If this detector has registered the complete passage of the previous strand stack, the section in question is empty. The signals of the individual detectors are processed in a common control in the housing 26, the control always "knowing" in which section a particular strand stack is currently located and which sections are empty and which are full due to the package-wise transport of the strand stacks from section to section . In this way, congestion in the sections or overfilling are excluded from them.

Weitere Einzelheiten des Teilmoduls "Litzenmagazin", insbesondere die Klemmen K₁ bis K₆ und die Detektoren 32 sind in unserer gleichzeitig eingereichten Patentanmeldung "Vorrichtung zur Hanhabung von Litzen für Kettfadeneinziehmaschinen" (Referenz: 5TX/253) beschrieben.Further details of the sub-module "heald magazine", in particular the clamps K₁ to K₆ and the detectors 32 are described in our simultaneously filed patent application "Device for handling healds for warp threading machines" (reference: 5TX / 253).

Nachfolgend soll nun die Separierstation ST beschrieben werden, wobei, wie schon erwähnt, auf die Offenbarung der eine Separierstation für Lamellen mit offenen Endösen beschreibenden US-A-5,184,380 Bezug genommen wird. Etwas vereinfacht kann gesagt werden, dass die Litzenseparierung als solche und die Mittel für deren Durchführung bei Litzen mit geschlossenen Endösen die gleichen sind wie bei solchen mit offenen Endösen, und dass der Unterschied bei der Uebergabe der separierten Litzen an den für den Transport der Litzen an ihre Einzugsposition vorgesehenen Litzenträger besteht.The separating station ST will now be described below, reference being made, as already mentioned, to the disclosure of US Pat. No. 5,184,380, which describes a separating station for lamellae with open end loops. To put it simply, it can be said that the strand separation as such and the means for carrying it out with strands with closed end loops are the same as those with open end loops, and that the difference in the transfer of the separated strands to those for the transport of the strands their stranded position is provided.

Der Litzenträger, der in der WO-A-92/05303 beschrieben ist, umfasst unter anderem zwei vertikal beabstandete Transportebenen, in deren jeder ein endloses Transportmittel in der Art eines Riemens oder einer Kette geführt ist. Die Transportmittel sind mit stiftartigen Litzenhaltern versehen, in die die Litzen mit ihren Endösen eingehängt werden. Die Mittel zur Uebergabe der separierten Litzen an den Litzenträger haben also die Funktion, die separierten Litzen auf ihren Tragschienen in Richtung zum Litzenträger zu verschieben und sie den Litzenhaltern zu übergeben.The heald carrier, which is described in WO-A-92/05303, comprises, inter alia, two vertically spaced transport planes, in each of which an endless transport means in the manner of a belt or a chain is guided. The means of transport are provided with pin-like strand holders, into which the strands are hung with their end loops. The means for transferring the separated strands to the strand holder therefore have the function of shifting the separated strands on their support rails in the direction of the strand holder and transferring them to the strand holders.

Zu diesem Zweck weisen die Tragschienen an ihrem den Litzenhaltern zugewandten Ende eine U- oder halbkreisförmige Ausnehmung auf, die im Niveau der Bewegungsbahn der Litzenhalter liegt und deren freies Ende umgreift. Dadurch überlappen sich die Enden der Tragschienen und der Litzenhalter, so dass eine sichere Litzenübergabe an die Litzenhalter gewährleistet ist.For this purpose, the support rails have at their end facing the strand holders a U-shaped or semicircular recess which lies in the level of the path of movement of the strand holders and engages around their free end. As a result, the ends of the mounting rails and the strand holder overlap, so that a reliable strand transfer to the strand holder is ensured.

Fig. 4 zeigt eine Ansicht der unteren Separierstufe der Separierstation ST in Richtung des Pfeiles IV von Fig. 3, also von der Litzenträger her gesehen, und Fig. 5 zeigt eine Draufsicht auf die untere Separierstufe in Richtung des Pfeiles V von Fig. 4. Wie in der schon mehrfach erwähnten US-A-5,184,380 beschrieben ist, ist in der Separierstufe ein Führungskanal 32 für einen Stapel von Litzen gebildet, der durch die Förderriemen 29 und die Anpressbürste 31 (Fig. 3) nach vorne gegen das in Fig. 5 rechte separierseitige Ende des Führungskanals 32 gedrückt wird. An diesem Ende ist vor dem Führungskanal 32 ein Anschlag 33 angeordnet, der an eine Führungsplatte 34 angearbeitet ist.FIG. 4 shows a view of the lower separation stage of the separation station ST in the direction of arrow IV of FIG. 3, that is to say seen from the heddle holder, and FIG. 5 shows a plan view of the lower separation stage in the direction of arrow V of FIG. 4. As described in the already mentioned US-A-5,184,380, a guide channel 32 is formed in the separating stage for a stack of strands, which through the conveyor belts 29 and the pressure brush 31 (FIG. 3) forward against the one in FIG. 5 right-hand end of the guide channel 32 is pressed. At this end, a stop 33 is arranged in front of the guide channel 32, which is worked on a guide plate 34.

Die vorderste Litze LI liegt ausserhalb des Führungskanals 32 und wird durch das pneumatisch angetriebene Separiermesser 18 seitlich aus dem Litzenstapel in eine Zwischenposition geschoben. Dabei wird durch die Litze LI ein einem Sensor 35 zugeordneter fingerartige Geber 36 (Fig. 6a) gegen den Sensor 35 bewegt, wodurch ein die Separierung bestätigendes Sensorsignal erzeugt wird. Dieses Sensorsignal löst einen Arbeitshub des ersten Uebergebers 19 aus, der die Litze entlang einer Führungskante der Führungsplatte 34 vom Litzenstapel weg gegen den in Fig. 6a bis 6d mit dem Bezugszeichen 37 bezeichneten Litzenhalter verschiebt.The foremost strand LI lies outside the guide channel 32 and is pushed laterally out of the strand stack into an intermediate position by the pneumatically driven separating knife 18. In this case, a finger-like transmitter 36 (FIG. 6a) assigned to a sensor 35 is moved against the sensor 35 by the wire LI, as a result of which a sensor signal confirming the separation is generated. This sensor signal triggers a working stroke of the first transmitter 19, which shifts the strand along a leading edge of the guide plate 34 away from the strand stack against the strand holder designated by reference number 37 in FIGS. 6a to 6d.

Wenn Litzen mit geschlossenen Endösen abgearbeitet werden, dann ragen im Bereich der Separierstation die Tragschienen 13 von der Klemme K₆ (Fig. 3) weg frei nach vorne zu den Litzenhaltern, und zwar über eine Länge von rund 25 cm. Es hat sich gezeigt, dass die freien Enden der Tragschienen 13 im Betrieb zu Vibrationen neigen, was sowohl die Separierung der Litzen als auch deren Uebergabe an die Litzenhalter störend beeinflussen kann. Zur Verhinderung derartiger Störungen und zur Ermöglichung einer sicheren Separierung und Uebergabe ist an den freien Enden der Tragschienen 13 im Bereich der Separierstation eine gesteuerte Schleuse vorgesehen, die im Normalzustand geschlossen ist und die Tragschiene fixiert, und die jeweils für einen Litzendurchgang kurzzeitig geöffnet wird.If strands are processed with closed end loops, then in the area of the separating station, the support rails 13 protrude freely away from the clamp K Fig (FIG. 3) to the strand holders, namely over a length of around 25 cm. It has been shown that the free ends of the mounting rails 13 vibrate during operation tend, which can interfere with both the separation of the strands and their transfer to the strand holder. To prevent such faults and to enable safe separation and transfer, a controlled lock is provided at the free ends of the support rails 13 in the area of the separation station, which is closed in the normal state and fixes the support rail, and which is briefly opened in each case for a strand passage.

Darstellungsgemäss ist die gesteuerte Schleuse durch ein Paar von Klemmen 38 und 39 gebildet, die je aus zwei Klemmbacken bestehen. Eine der beiden Klemmbacken trägt jeweils einen vorspringenden Kegel 40, der zum Eindringen in eine entsprechende Bohrung der Tragschiene 13 vorgesehen ist. Die beiden Kegel 40 des Klemmenpaares sind zu verschiedenen Seiten der Tragschiene 13 angeordnet, so dass der Kegel 40 der einen Klemme von der einen und der Kegel 40 der anderen Klemme von der andren Seite in die Tragschiene einfährt.As shown, the controlled lock is formed by a pair of clamps 38 and 39, each consisting of two jaws. One of the two clamping jaws each carries a projecting cone 40, which is provided for penetration into a corresponding bore in the mounting rail 13. The two cones 40 of the pair of clamps are arranged on different sides of the mounting rail 13, so that the cone 40 of the one clamp moves into the mounting rail from the one side and the cone 40 of the other clamp from the other side.

Der Antrieb der Klemme 38, 39 erfolgt durch eine von einem Pneumatikstössel 41 angetriebene Kulisse 42, welche auf entsprechend ausgebildete Enden der Klemmbacken wirkt und diese formschlüssig antreibt. Dadurch ist die Verstellung der Klemmen 38, 39 jederzeit voll unter Kontrolle.The clamp 38, 39 is driven by a link 42 driven by a pneumatic tappet 41, which acts on appropriately designed ends of the clamping jaws and drives them in a form-fitting manner. As a result, the adjustment of the terminals 38, 39 is fully under control at all times.

Die Klemmen 38, 39 weisen einen gegenseitigen Abstand von einigen Millimetern auf. Die Litzenübergabe geht so vor sich, dass die separierte Litze LI zuerst in einem ersten Schritt vom ersten Uebergeber 19 durch die geöffnete erste Klemme 38 bis an die geschlossene zweite Klemme 39 (die Position der Litze LI nach diesem ersten Schritt ist in Fig. 4 dargestellt) und anschliessend, bei geschlossener erster Klemme 38, durch die offene zweite Klemme 39 zum Litzenhalter 37 transportiert und in diesen eingehängt wird. Der zweite Transportschritt von der zweiten Klemme 39 zum Litzenhalter 37 erfolgt durch einen zweiten Uebergeber 43.The terminals 38, 39 are spaced a few millimeters apart. The strand transfer takes place in such a way that the separated strand LI begins in a first step from the first transmitter 19 through the opened first terminal 38 to the closed second clamp 39 (the position of the strand LI after this first step is shown in FIG. 4) and then, with the first clamp 38 closed, transported through the open second clamp 39 to the strand holder 37 and hooked into it. The second transport step from the second clamp 39 to the strand holder 37 is carried out by a second transmitter 43.

In den Figuren 6a bis 6d ist der Funktionsablauf bei der Litzenseparierung und -übergabe schematisch dargestellt. Die in den einzelnen Figuren eingezeichneten Pfeile symbolisieren jeweils eine Bewegung und deren Richtung, die unmittelbar vor dem in der betreffenden Figur dargestellten Momentanzustand erfolgt ist.FIGS. 6a to 6d schematically show the functional sequence for strand separation and transfer. The arrows drawn in the individual figures each symbolize a movement and its direction, which occurred immediately before the instantaneous state shown in the figure in question.

Fig. 6a zeigt den Momentanzustand unmittelbar nach der Separierung. Die vorderste Litze LI ist mit dem Separiermesse 18 seitlich aus dem Litzenstapel herausgeschoben oder herausgebogen worden, wobei die Litzenendösen weiterhin an den Tragschienen 13 geführt sind. Die Litze LI hat bei ihrer seitlichen Verschiebung den Geber 36 gegen den Sensor 35 bewegt, der unmittelbar nach erfolgter Separierung ein Separiersignal erzeugt. Zu diesem Zeitpunkt ist die erste Klemme 38 der Schleuse gerade geöffnet worden und die zweite Klemme 39 ist geschlossen.6a shows the instantaneous state immediately after the separation. The foremost strand LI has been pushed or bent sideways out of the strand stack with the separating measurement 18, the strand end loops still being guided on the mounting rails 13. During its lateral displacement, the stranded wire LI has moved the transmitter 36 against the sensor 35, which generates a separation signal immediately after the separation has taken place. At this time, the first clamp 38 of the lock has just been opened and the second clamp 39 is closed.

Fig. 6b zeigt den ersten Schritt der Litzenübergabe; dieser Zustand ist auch in Fig. 4 dargestellt. Das durch die vollständig separierte Litze ausgelöste Separiersignal des Sensors 35 hat einen Arbeitshub des ersten Uebergebers 19 ausgelöst, wodurch die separierte Litze LI von der in Fig. 6a dargestellten Zwischenposition durch die offene erste Klemme 38 an die geschlossene zweite Klemme 39 transportiert wird. Am Ende dieser Transportbewegung tritt der Abtrennfinger 20 in Aktion und trennt durch eine Schwenkbewegung quer zur Tragschiene 13 die eventuell im Bereich des Fadenauges mit der nächsten Litze verkeilte separierte Litze LI vollständig vom Litzenstapel.6b shows the first step of the strand transfer; this state is also shown in FIG. 4. The separation signal of the sensor 35 triggered by the completely separated strand has triggered a working stroke of the first transmitter 19, whereby the separated strand LI from that shown in FIG. 6a The intermediate position is transported through the open first clamp 38 to the closed second clamp 39. At the end of this transport movement, the separating finger 20 comes into action and completely separates the separated strand LI, possibly wedged in the area of the thread eye with the next strand, by a pivoting movement transverse to the support rail 13 from the strand stack.

Sobald der erste Uebergeber 10 vollständig ausgefahren ist und die separierte Litze LI die zweite Klemme 39 erreicht hat, erfolgt der in Fig. 6c dargestellte Funktionsschritt, der die durch die beiden Klemmen 38 und 39 gebildete Schleuse betrifft. Und zwar wird nun die Schleuse für die Uebergabe der Litze LI an den Litzenhalter 37 vorbereitet. Dazu wird zuerst die erste Klemme 38 geschlossen und anschliessend die zweite Klemme 39 geöffnet, womit der in Fig. 6c dargestellte Zustand erreicht ist.As soon as the first transmitter 10 is fully extended and the separated strand LI has reached the second terminal 39, the functional step shown in FIG. 6c takes place, which relates to the lock formed by the two terminals 38 and 39. The lock is now being prepared for the transfer of the strand LI to the strand holder 37. For this purpose, the first terminal 38 is first closed and then the second terminal 39 is opened, which means that the state shown in FIG. 6c is reached.

Fig. 6d zeigt den Zweiten und letzten Schritt der Litzenübergabe von der zweiten Klemme 39 auf den Litzenhalter 37. Nach dem Oeffnen der zweiten Klemme 39 wird der zweite Uebergeber 43 aus seiner in den Figuren 6a bis 6c gezeigten Ruhelage ausgefahren und trifft auf die vor der jetzt offenen zweiten Klemme 39 positionierte Litze LI. Die Litze wird durch den zweiten Uebergeber 43 auf der Tragschiene 13 weiter verschoben und wird schliesslich auf den nadelförmigen Litzenhalter 37 gehängt. Während dieser Zeit hat sich der erste Uebergeber 19 in seine Ruhestellung zurückbewegt, womit der in Fig. 6d dargestellte Zustand erreicht ist.6d shows the second and last step of the strand transfer from the second clamp 39 to the strand holder 37. After the second clamp 39 has been opened, the second transmitter 43 is extended from its rest position shown in FIGS. 6a to 6c and meets the position before now open second terminal 39 positioned wire LI. The strand is shifted further by the second transmitter 43 on the mounting rail 13 and is finally hung on the needle-shaped strand holder 37. During this time, the first transmitter 19 has moved back into its rest position, which means that the state shown in FIG. 6d is reached.

Nachdem ein entsprechender Sensor die Uebernahme der Litze durch die Litzenhalter 37 detektiert hat (siehe dazu WO-A-92/05303, Fig. 3) wird auch der zweite Uebergeber 43 in seine Ruhelage zurückbewegt und die zweite Klemme 39 wird geschlossen. Dann wird die erste Klemme 38 geöffnet und das Separiermesser 18 wird in seine Ausgangslage seitlich neben dem Führungskanal 32 zurückbewegt. Damit kann die vorderste Litze des Litzenstapels aus dem Führungskanal 32 heraustreten und durch eine entsprechende Querbewegung des Separiermesser 18 separiert werden, womit dann wieder der in Fig. 6a dargestellte Momentanzustand erreicht ist.After a corresponding sensor has detected the takeover of the wire by the wire holder 37 (see WO-A-92/05303, FIG. 3), the second transmitter 43 is also moved back into its rest position and the second terminal 39 is closed. Then the first clamp 38 is opened and the separating knife 18 is moved back to its starting position laterally next to the guide channel 32. The foremost strand of the strand stack can thus emerge from the guide channel 32 and be separated by a corresponding transverse movement of the separating knife 18, with which the instantaneous state shown in FIG. 6a is reached again.

In den Figuren 4 und 5 ist die auf der unteren Profilschiene 16 montierte untere Stufe der Separierstation ST (Fig. 3) dargestellt; die obere Stufe ist spiegelbildlich dazu an der oberen Profilschiene 17 montiert, wobei der Abtrennfinger 20 Bestandteil der oberen Stufe bildet. Der Abtrennfinger 20 kann als sogenannter Zwillings- oder Tandemfinger ausgebildet sein und eine stimmgabelförmige Gestalt aufweisen. Dieser Tandemfinger wird bei der Separierung von Litzen mit offenen Endösen verwendet.FIGS. 4 and 5 show the lower stage of the separation station ST (FIG. 3) mounted on the lower profile rail 16; the upper step is mirrored to the upper profile rail 17, the separating finger 20 forming part of the upper step. The separating finger 20 can be designed as a so-called twin or tandem finger and have a tuning fork shape. This tandem finger is used when separating strands with open end loops.

Die dargestellte und beschriebene Separierstation für Litzen mit geschlossenen Endösen eignet sich selbstverständlich auch für die Separierung von Litzen mit offenen Endösen, sie ist aber aufwendiger und teuerer als die in der US-A-5,184,380 beschriebene Separierstation für Litzen mit offenen Endösen.The illustrated and described separation station for strands with closed end loops is of course also suitable for the separation of strands with open end loops, but it is more complex and expensive than the separation station for strands with open end loops described in US Pat. No. 5,184,380.
