Abstract

A heald singularizing system includes a selecting member (21) for the healds (LI) fed in the form of a stack (LS). The selecting member (21) separates the front-most heald (LI1) from the stack and makes it available for the drawing-in of the warp threads. The selecting member (21) is formed by a piston which can perform a stroke essentially transversely to the heald stack (LS), during which the heald (LI1) is displaced from the heald stack (LS) into an intermediate position (ZP). Transfer means (24) transfers the respective heald (LI1) from its intermediate position (ZP) to a transport unit (25) for taking it to its drawing-in position. All types of healds can be selected from the heald stack, and neither a special preparation of the healds nor the use of a special type of heald is necessary. The heald separation and the further removal are completely uncoupled, to permit the use of means optimally adapted to the individual functions and also to simplify considerably the rectification of faults.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Vereinzeln von Litzen für Kettfadeneinziehmaschinen, mit einem Abteilorgan für die in Form eines Stapels zugeführten Litzen, welches die vorderste Litze vom Stapel trennt und für den Kettfadeneinzug bereitstellt.The present invention relates to a device for separating strands for warp threading machines, with a dividing element for the strands fed in the form of a stack, which separates the foremost strand from the stack and provides it for the warp thread pulling in.

Bei bisher bekannten Vorrichtungen dieser Art ist das Abteilorgan durch eine Nadel gebildet, welche unmittelbar nach der vordersten Litze des Litzenstapels in diesen hineinsticht und anschliessend die vorderste Litze in Längsrichtung des Litzenstapels, also in Zuführrichtung, an die Einzugsposition verschiebt. Die verwendeten Litzen sind entweder an ihren Schmalkanten an der Abteilstelle mit einer Zuspitzung versehen, oder sie müssen ein sogenanntes Schlüsselloch aufweisen. Dies bedeutet, dass Litzen ohne zugespitzte Schmalkanten oder Schlüsselloch bisher nicht automatisch eingezogen werden konnten.In previously known devices of this type, the compartment member is formed by a needle which sticks directly into the foremost strand of the strand stack and subsequently shifts the foremost strand in the longitudinal direction of the strand stack, that is to say in the feed direction, to the retracted position. The strands used are either tapered at their narrow edges at the compartment location, or they must have a so-called keyhole. This means that healds without tapered narrow edges or keyholes have so far not been able to be drawn in automatically.

Eine solche Vorrichtung für Litzen mit Zugespitzten Schmalkanten ist aus der US 3,121,936 bekannt. Bei dieser Vorrichtung werden die Litzen mit einem keilförmigen, seitlich ansetzenden Abteilorgan in Längsrichtung des Litzenstapels abgetrennt und weiterbewegt. Eine weitere Vorrichtung, bei der die Litzen ebenfalls direkt aus dem Litzenstapel und in seiner Längsrichtung abgeteilt und weiterbewegt werden, ist aus der JP-A-1 280 051 bekannt. Hier sind die Litzen bezüglich ihrer Dicke genau auf ein Abteilorgan abgestimmt, das an den Endflächen der Litzen ansetzt.Such a device for strands with tapered narrow edges is known from US 3,121,936. In this device, the strands are separated with a wedge-shaped, laterally attached compartment member in the longitudinal direction of the strand stack and moved on. A further device, in which the strands are also divided and moved directly out of the strand stack and in its longitudinal direction, is known from JP-A-1 280 051. Here, the strands are precisely matched in terms of their thickness to a compartment organ that attaches to the end faces of the strands.

Durch die Erfindung soll nun eine universell einsetzbare Vorrichtung zum Vereinzeln von Litzen angegeben werden, welche das Abarbeiten aller Arten von Litzen ermöglicht.The invention is now intended to provide a universally usable device for separating strands, which enables all types of strands to be processed.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Abteilorgan durch einen quer zum Litzenstapel hubbewegbaren Kolben gebildet ist, bei dessen Arbeitshub die vorderste Litze seitwärts aus dem Litzenstapel formschlüssig in eine Zwischenposition transportiert wird.This object is achieved according to the invention in that the compartment member is formed by a piston which can be moved transversely to the stack of strands, during its working stroke the foremost strand is positively transported sideways out of the strand stack into an intermediate position.

Bei der erfindungsgemässen Vorichtung wird also die vorderste Litze beim Abteilen nicht so wie bisher in Zuführrichtung weitergeschoben, sondern seitlich aus dem Litzenstapel herausbewegt. Dies bedeutet eine Entkopplung zwischen dem eigentlichen Vereinzelungsvorgang und der folgenden Abarbeitung, welche es gestattet, für die nun entkoppelten Vorgänge optimal angepasste Mittel zu verwenden. Der hubbewegliche Kolben ist in der Lage, alle Arten von Litzen vom Litzenstapel abzuteilen, so dass die Litzen nicht speziell präpariert zu werden brauchen. Da das Abteilen formschlüssig erfolgt, sind die Litzen jederzeit voll unter Kontrolle.In the device according to the invention, the foremost strand is not pushed further in the feed direction as before, but is moved laterally out of the strand stack. This means a decoupling between the actual separating process and the subsequent processing, which makes it possible to use optimally adapted means for the now decoupled processes. The lifting piston is able to separate all types of strands from the strand stack, so that the strands do not need to be specially prepared. Since the compartments are form-fitting, the strands are fully under control at all times.

Eine bevorzugte Weiterbildung der erfindungsgemässen Vorrichtung ist dadurch gekennzeichnet, dass in der genannten Zwischenposition ein Uebergabemittel zur Uebergabe der jeweiligen Litze an eine Transporteinheit für den Transport der Litze an ihre Einzugsposition vorgesehen ist.A preferred further development of the device according to the invention is characterized in that a transfer means is provided in the intermediate position mentioned for transferring the respective strand to a transport unit for transporting the strand to its retracted position.

Dieses Uebergabemittel stellt eine Schnittstelle zwischen der eigentlichen Abteilvorrichtung und der Transporteinheit dar und eröffnet bei geeigneter Ausbildung die Möglichkeit, bei Bedarf, beispielsweise bei Störungen, die Verbindung zwischen Abteilvorrichtung und Transporteinheit unterbrechen zu können.This transfer means represents an interface between the actual compartment device and the transport unit and, with a suitable training, opens up the possibility of being able to interrupt the connection between the compartment device and the transport unit if necessary, for example in the event of faults.

Gemäss Fig. 1 besteht die Einziehmaschine aus einem Grundgestell 1 und aus verschiedenen in diesem angeordneten Baugruppen, welche jede ein Funktionsmodul darstellen. 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 Rahmens 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 Rahmen 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 Rahmen 5 wird von der Hebevorrichtung 4 nach oben gehoben und nimmt dann die dargestellte Lage ein.1, the drawing-in machine consists of a base frame 1 and of various assemblies arranged in it, each of which represents 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 frame 5 on which the warp threads KF are stretched. This clamping takes place before the actual pulling-in and at a location separate from the drawing-in machine, the frame 5 being positioned at the lower end of the lifting device 4 in the immediate vicinity of the warp beam 3. The warp beam carriage 2 with warp beam 3 and lifting device 4 is used for pulling in moved to the so-called upgrade side of the drawing machine and the frame 5 is lifted up by the lifting device 4 and then assumes the position shown.

Der Rahmen 5 und der Kettbaum 3 werden in Längsrichtung des Grundgestells 1 verschoben. Bei dieser Verschiebung werden die Kettfäden KF an einer 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 (USTER - eingetragenes Warenzeichen der Zellweger Uster AG) verwendete Abteileinrichtung eingesetzt werden.The frame 5 and the warp beam 3 are moved in the longitudinal direction of the base frame 1. With this shifting, the warp threads KF are guided past a thread separation group 6 and 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. The sectioning device used in the USTER TOPMATIC warp knitting machine (USTER - registered trademark of Zellweger Uster AG), for example, can be used for dividing the warp threads.

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. This control box contains the control computer for each so-called Main module is a module computer, 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 1 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 Rahmen 5 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 separating group 6, which presents the warp threads KF to be drawn in to the pull-in needle 7, and the movement path 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 1, which supports the already mentioned upgrade side separates from 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, lamellae and sheets) with the drawn-in warp threads can be removed on the tear-down side. During the pulling-in, the frame 5 with the warp threads KF and the warp beam carriage 2 with the warp beam 3 are moved past the thread separation group 6 to the right, the pull-in needle 7 successively taking out the warp threads KF stretched on the frame 5.

Wenn alle Kettfäden KF eingezogen sind und der Rahmen 5 leer ist, befindet sich der letztere zusammen mit dem Kettbaumwagen 2, dem Kettbaum 3 und der Hebevorrichtung 4 auf der Abrüstseite.When all the warp threads KF have been drawn in and the 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.

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 aufgestapelt, 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 die 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 lamellae LA arrive on lamella 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 Webschäfte 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 Webschäften 14 ist ein Teil des Webblatts WB zu erkennen. Diese 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 healds LI are individually brought into their retracted position and, after they have been drawn in, distributed to the corresponding heald frames 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 it has been drawn in, the sheet is also on the dismantling side. To the right of the heald frames 14 is a part of the reed WB. 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, Webschäften 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 crockery trolley 15 is provided on the dismantling side. This is inserted together with the slat support rails 12, heald frames 14 and a holder for the reed into the base frame 1 in the position shown and carries the dishes with the drawn-in warp threads KF after being drawn in. At this time, the warp beam carriage 2 with the warp beam 3 is located directly in front of the dishwashing carriage 15. Now, using the lifting device 4, the dishes are reloaded from the dishwashing carriage 15 onto the warp beam carriage 2, which then carries the warp beam 3 and the pulled-in dishes and to the weaving machine in question or can be moved to an interim storage facility.

Die Funktionsweise der einzelnen Baugruppen ist nicht Gegenstand der Erfindung und soll daher hier nicht weiter erläutert werden. Wesentlich ist, dass die Funktionen auf mehrere Module verteilt sind, und dass diese Module praktisch autonome Maschinen darstellen, welche von einem 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. Wenn man die Struktur der beschriebenen Einziehmaschine betrachtet, dann erhält das System Einziehmaschine Einzugsdaten, Steuerdaten, Geschirr und Garn sowie Energie und liefert aufbereitete Betriebsdaten, Zustandsinformationen und das eingezogene Geschirr.The mode of operation of the individual assemblies is not the subject of the invention and is therefore not to be explained further here. It is essential that the functions are distributed over several modules and that these modules are practically autonomous machines that are controlled by a 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. If you look at the structure of the feeding machine described, the feeding machine system receives feed data, control data, tableware and yarn as well as energy and supplies prepared operating data, status information and the tableware being pulled in.

In den Fig. 2 bis 4 ist die mit SP bezeichnete Separierstufe für die Litzen LI dargestellt. Fig. 2 zeigt eine nicht maßstab- und auch nicht proportionsgetreue Perspektivdarstellung, welche einer übersichtlichen Erklärung des Separierprinzips dienen soll, die Fig. 3 und 4 zeigen je eine Ansicht im Maßstab von 1:1.2 to 4, the separation stage labeled SP for the strands LI is shown. 2 shows a perspective representation which is not true to scale and also not true to proportion, which is intended to provide a clear explanation of the separation principle; FIGS. 3 and 4 each show a view on a scale of 1: 1.

Wie schon bei der Beschreibung von Fig. 1 erwähnt wurde, werden die Litzen LI auf Schienen 13 aufgereiht und auf diesen automatisch oder manuell zur Separierstufe SP verschoben. Die Verschiebungsrichtung ist in Fig. 2 mit einem Pfeil A bezeichnet, die Verschiebung erfolgt vorzugsweise automatisch. Zu diesem Zweck liegt der Litzenstapel LS an der einen Schmalkante der Litzen LI an einer Führungsschiene 16 an, entlang welcher die Verschiebung erfolgt. An der anderen, in der Figur vorderen Schmalkante der Litzen ist ein Transportmittel angeordnet, welches den Litzenstapel LS in Richtung des Pfeiles A verschiebt. Dieses Transportmittel ist darstellungsgemäss durch eine bürstenartige Rolle 17 gebildet, welche an der vorderen Schmalkante der Litzen LI angreift und an ihrem Mantel einen für die Mitnahme der Litzen geeigneten bürsten- oder plüschartigen oder elastischen Belag aufweist. Bei Rotation der Rolle 17 in der mit einem Pfeil B bezeichneten Drehrichtung, werden die Litzen LI in Richtung des Pfeiles A geschoben. Anstatt der Rolle 17 oder in Kombination mit dieser, kann auch ein über zwei Rollen gespanntes Transportband verwendet werden, welches entweder mit einem geeigneten Belag oder mit einzelnen, vorzugsweise bürstenartigen, Mitnahmeelementen versehen ist.As already mentioned in the description of FIG. 1, the strands LI are lined up on rails 13 and are automatically or manually shifted to the separating stage SP. The direction of displacement is designated by an arrow A in FIG. 2, the displacement preferably takes place automatically. For this purpose, the strand stack LS lies on the one narrow edge of the strand LI on a guide rail 16, along which the displacement takes place. On the other narrow edge of the strands, which is the front in the figure, a transport means is arranged which displaces the strand stack LS in the direction of arrow A. As shown, this means of transport is formed by a brush-like roller 17 which engages on the front narrow edge of the strands LI and has a brush-like or plush-like or elastic covering which is suitable for carrying the strands on its jacket. When the roller 17 rotates in the direction of rotation indicated by an arrow B, the strands LI are pushed in the direction of the arrow A. Instead of the roller 17 or in combination with this, a conveyor belt stretched over two rollers can also be used be, which is either provided with a suitable covering or with individual, preferably brush-like, driving elements.

Unmittelbar vor der Separierstufe SP ist auch im Bereich der vorderen Schmalkante der Litzen LI eine Führungsschiene 18 angeordnet, welche eine schräge, trichterartige Einlaufpartie aufweist, so dass die Litzen LI der Separierstufe in einem durch die beiden Führungsschienen 16 und 18 gebildeten Führungskanal geordnet zugeführt werden. In der Separierstufe wird nun jeweils die vorderste Litze LI1 des Litzenstapels LS von diesem separiert oder abgeteilt und an eine Transporteinheit übergeben, welche die einzelnen Litzen nacheinander zur Einziehposition bringt, in welcher der Kettfadeneinzug erfolgt.Immediately in front of the separation stage SP, a guide rail 18 is also arranged in the region of the front narrow edge of the strands LI, which has an oblique, funnel-like inlet section, so that the strands LI are supplied to the separation stage in an orderly manner in a guide channel formed by the two guide rails 16 and 18. In the separating stage, the foremost heald LI1 of the heald stack LS is separated or separated from this and transferred to a transport unit, which brings the individual healds one after the other to the pull-in position in which the warp thread is drawn in.

Es sind zwei Separierstufen SP vorgesehen, von denen die eine im Bereich des oberen und die andere im Bereich des unteren Endes der Litzen LI auf diese einwirkt (siehe Fig. 3). Beide Separierstufen sind synchron angetrieben.Two separation stages SP are provided, one of which acts on the strands LI in the region of the upper end and the other in the region of the lower end (see FIG. 3). Both separation stages are driven synchronously.

Anhand von Fig. 2, in welcher die Hauptteile der im Bereich des oberen Litzenendes angeordneten Separierstufe SP dargestellt sind, soll nun das Funktionsprinzip der Litzenseparierung erläutert werden: Unmittelbar vor dem Entnahmeende des durch die Führungsschienen 16 und 18 gebildeten Führungskanals ist ein quer zu diesem verlaufenden Anschlagelement angeordnet, welches durch eine von einem im wesentlichen prismatischen Führungskörper 19 abstehende Rippe 20 gebildet ist. Deren Abstand vom Entnahmeende des Führungskanals ist so gewählt, dass sich die an der Rippe 20 anliegende vorderste Litze LI1 vollständig ausserhalb des Führungskanals befindet. Der Abstand zwischen Rippe 20 und Führungskanal ist einstellbar; die Einstellung erfolgt vorzugsweise durch Auswechslung des Führungskörpers 19, wobei verschiedene Führungskörper 19 zur Verfügung stehen, bei denen die Anschlagfläche der Rippen 20 von der entsprechenden Basisfläche des Führungskörpers 19 jeweils verschieden stark abgestuft ist. In der Praxis sind drei bis vier derartige Führungskörper 19 ausreichend, mit denen der ganze Bereich der vorkommenden Litzenstärken abgedeckt werden kann.2, in which the main parts of the separation stage SP arranged in the area of the upper strand end are shown, the functional principle of the strand separation is now to be explained: Immediately before the end of the removal of the guide channel formed by the guide rails 16 and 18 a stop element running transversely to this is arranged, which is formed by a rib 20 projecting from an essentially prismatic guide body 19. The distance from the removal end of the guide channel is selected such that the foremost strand LI1 resting on the rib 20 is located completely outside the guide channel. The distance between rib 20 and guide channel is adjustable; the setting is preferably carried out by replacing the guide body 19, various guide bodies 19 being available in which the stop surface of the ribs 20 is graduated to different degrees from the corresponding base surface of the guide body 19. In practice, three to four guide bodies 19 of this type are sufficient, with which the entire range of the strand thicknesses that occur can be covered.

Die vorderste Litze LI1 liegt also im Bereich der Rippe 20 ausserhalb des Führungskanals, ist aber mit ihren Endösen immer noch auf den Schienen 13 gehalten. Nun erfolgt die Separierung, also die Trennung der vordersten Litze LI1 vom Litzenstapel LS, zu welchem Zweck der zwischen den Endösen liegende Mittelteil der vordersten Litze LI1 seitlich aus dem Litzenstapel herausgeschoben wird. Dieses Herausschieben erfolgt durch ein kolbenartiges Abteilorgan 21, welches im Führungskörper 19 quer zur Längsrichtung der Litzen LI und quer zu deren Führungsrichtung A hubverstellbar gelagert ist und bei seinem Arbeitshub in Richtung des Pfeiles C den Mittelteil der vordersten Litze LI1 vom Litzenstapel LS weg formschlüssig in die gestrichelt eingezeichnete Zwischenposition ZP schiebt. Bei dieser Verschiebung gleitet der genannte Mittelteil entlang einer Führungsebene 22 bis er an einem Anschlag 23 zum Stillstand kommt. In der Zwischenposition ZP ist die Litze an ihren Endösen von den Schienen 13 und im Bereich ihres Mittelteils zwischen dem Anschlag 23 und der Vorderkante des Abteilorgans 21 gehalten.The foremost strand LI1 is therefore in the region of the rib 20 outside the guide channel, but its end loops are still held on the rails 13. Now the separation, that is, the separation of the foremost strand LI1 from the strand stack LS takes place, for which purpose the middle part of the foremost strand LI1 lying between the end loops is pushed laterally out of the strand stack. This pushing out takes place by a piston-like compartment member 21, which is mounted in the guide body 19 transversely to the longitudinal direction of the strands LI and transversely to their guide direction A and During its working stroke in the direction of arrow C, the middle part of the foremost strand LI1 is positively pushed away from the strand stack LS into the intermediate position ZP shown in broken lines. During this displacement, the mentioned middle part slides along a guide plane 22 until it comes to a stop at a stop 23. In the intermediate position ZP, the braid is held at its end loops by the rails 13 and in the region of its middle part between the stop 23 and the front edge of the compartment member 21.

Unterhalb der Führungsebene 22 ist ein in Richtung des Pfeils D verschiebbarer Stössel 24 angeordnet, dessen Stirnfläche gegenüber der Führungsebene 22 entgegen der Richtung des Pfeils D leicht zurückversetzt ist. Der Stössel 24 wird nun in Pfeilrichtung D bewegt und verschiebt den Mittelteil der Litze LI1 von der Zwischenposition ZP auf einer schrägen Bahn parallel zur schrägen Stirnfläche der Rippe 20 bis in eine strichpunktierte eingezeichnete Uebergabeposition UP. Bei dieser Verschiebung durch den Stössel 24 entspannt sich der bei der Separierung gebogene Mittelteil der Litze wieder und nimmt in der Uebergabeposition UP wieder seine gerade Lage ein. Wenn man die Uebergabeposition UP mit der Ausgangsposition vor der Separierung vergleicht, dann hat zwischen diesen beiden Positionen, über den Umweg der Zwischenposition ZP nur eine Verschiebung in der Transportrichtung A stattgefunden, wobei die Litze während der ganzen Verschiebung formschlüssig geführt ist. In der Uebergabeposition UP ist die Litze mit ihren Endösen nicht mehr von den Schienen 13 gehalten, sondern auf nadelartige Haltemittel 25 gesteckt, welche Teil einer Transporteinheit zum Transport der Litze an die Einziehposition bilden. Dann wird der Stössel 24 in seine Ausgangsposition zurückbewegt und das schon während des Transporthubs des Stössels 24 entgegen der Richtung des Pfeils C in seine Ausgangslage zurückbewegte Abteilorgan 21 kann einen neuerlichen Arbeitshub durchführen und dabei die nächste Litze LI vom Litzenstapel LS separieren.Arranged below the guide plane 22 is a plunger 24 which can be displaced in the direction of the arrow D and the end face of which is slightly set back in relation to the guide plane 22 against the direction of the arrow D. The plunger 24 is now moved in the direction of arrow D and shifts the central part of the strand LI1 from the intermediate position ZP on an inclined path parallel to the inclined end face of the rib 20 to a transfer position UP shown in broken lines. During this displacement by the plunger 24, the middle part of the strand bent during the separation relaxes again and returns to its straight position in the transfer position UP. If one compares the transfer position UP with the starting position before the separation, then only a shift in the transport direction A has taken place between these two positions, via the detour of the intermediate position ZP, the braid being positively guided during the entire shift is. In the transfer position UP, the heald with its end loops is no longer held by the rails 13, but instead is placed on needle-like holding means 25, which form part of a transport unit for transporting the heald to the retracted position. Then the plunger 24 is moved back into its starting position and the compartment member 21, which has already moved back to its starting position against the direction of the arrow C during the transport stroke of the plunger 24, can carry out a new working stroke and thereby separate the next strand LI from the strand stack LS.

Die Figuren 3 und 4 zeigen, teilweise im Schnitt, eine maßstabgetreue Darstellung der beiden Separierstufen SP und von deren Anordnung. Jede der Separierstufen SP ist auf einem Träger 26 befestigt, von denen in der Figur nur derjenige für die obere Separierstufe eingezeichnet ist. Man erkennt an der in Fig. 3 rechten Seite der Litze LI das Abteilorgan 21, welches von einem pneumatisch antreibbaren Kolben 27 getragen ist. Der Kolben 27 ist in einem mit Druckluftanschlüssen versehenen Gehäuse 28 gelagert. Das Abteilorgan 21 ist im Führungskörper 19 geführt und ist von einem Anschlagbolzen 29 zur Begrenzung seines Hubes durchsetzt. Im Bereich seines vorderen, die Litze LI separierenden Teils, ist das Abteilorgan U-förmig ausgebildet und umgreift die Rippe 20.Figures 3 and 4 show, partly in section, a scale representation of the two separation stages SP and their arrangement. Each of the separation stages SP is attached to a carrier 26, of which only that for the upper separation stage is shown in the figure. The compartment member 21, which is carried by a pneumatically drivable piston 27, can be seen on the right side of the strand LI in FIG. 3. The piston 27 is mounted in a housing 28 provided with compressed air connections. The compartment member 21 is guided in the guide body 19 and is penetrated by a stop pin 29 to limit its stroke. In the area of its front part, which separates the strand LI, the compartment organ is U-shaped and engages around the rib 20.

An der in Fig. 3 linken Seite der Litze LI sind ein erster Bauteil 30, bestehend aus einem auf dem Träger 26 befestigten Grundkörper 31 und aus einem auf diesem befestigten Sensor 32 mit einer Kontaktfeder 33 (siehe Fig. 4), ein zweiter, ebenfalls auf dem Träger 26 befestigter Bauteil 34 mit Führungsebene 22 und Anschlag 23, sowie die Führungsschiene 16 zu erkennen. Der Sensor 32 dient zur Detektion der Litzenseparierung, indem die Kontaktfeder 33 durch die Litze LI bei deren Verschiebung in die Zwischenposition ZP gegen den Sensor 32 gedrückt wird. Generell ist zu sagen, dass auch die Bewegung des Abteilorgans 21 und die Bewegung des Stössels 24 durch Sensoren überwacht wird. Wenn einer dieser Sensoren nicht anspricht, dann wird die betreffende Funktion repetiert.On the left side of the stranded wire LI in FIG. 3, a first component 30, consisting of a base body 31 fastened on the carrier 26 and a sensor 32 fastened thereon with a contact spring 33 (see FIG. 4), is also a second one component 34 fastened on the carrier 26 with guide plane 22 and stop 23, and the guide rail 16. The sensor 32 is used to detect the strand separation, in that the contact spring 33 is pressed against the sensor 32 by the strand LI when it is displaced into the intermediate position ZP. In general, it can be said that the movement of the compartment member 21 and the movement of the ram 24 are monitored by sensors. If one of these sensors does not respond, the function in question is repeated.

Wie in Fig. 3 weiter zu entnehmen ist, ist am Träger 26 ein weiteres Kolbengehäuse 35 befestigt, in welchem ein pneumatisch antreibbarer Kolben 36 gelagert ist. Dieser Kolben ist mit einem messerartigen Schwenkhebel 37 gelenkig verbunden, welche bei Betätigung des Kolbens 36 in die Ebene der Litzen LI geschwenkt wird, um eventuell an den Litzenaugen LA aneinander haftende Litzen mechanisch voneinander zu trennen. Der Verstellweg des Schwenkhebels 37 ist durch einen Anschlag 38 begrenzt, dessen Lage auf die Maximallänge der verwendeten Litzen LI ausgelegt ist. Wenn so, wie in Fig. 3 angedeutet, kürzere Litzen abgearbeitet werden sollen, wird auf dem Träger 26 ein zusätzlicher, strichpunktiert eingezeichneter Anschlagbolzen 39 montiert, um den Verstellweg des Schwenkhebels 37 auf die obere der beiden ebenfalls strichpunktiert eingezeichneten Endlagen zu begrenzen.As can also be seen in FIG. 3, a further piston housing 35 is fastened to the carrier 26, in which a pneumatically drivable piston 36 is mounted. This piston is connected in an articulated manner to a knife-like pivot lever 37, which is pivoted into the plane of the strands LI when the piston 36 is actuated, in order to mechanically separate strands adhering to each other from the strand eyes LA. The adjustment path of the pivot lever 37 is limited by a stop 38, the position of which is designed for the maximum length of the strands LI used. If, as indicated in FIG. 3, shorter strands are to be processed, an additional stop bolt, shown in dash-dot lines, is placed on the carrier 26 39 mounted in order to limit the adjustment path of the pivot lever 37 to the upper of the two end positions, which are also shown in broken lines.

Aus Fig. 4 ist die Anordnung des ebenfalls pneumatisch betätigbaren Stössel 24 ersichtlich, welcher in Fig. 3 der Uebersichtlichkeit halber nicht eingezeichnet ist. Der Stössel 24 ist jeweils an der Innenseite der beiden Separierstufen angeordnet, also unterhalb der oberen und oberhalb der unteren Separierstufe SP. Darstellungsgemäss liegt die Längsachse des im wesentlichen prismatischen Stössels 24 schräg zur Zuführrichtung A der Litzen LI und seine die Litzen LI kontaktierende Stirnfläche verläuft entsprechend schräg zur Längsachse, oder mit anderen Worten, parallel zur Längsachse des Abteilorgans 21 (Pfeil C). Der Stössel 24 weist einen Längsschlitz 40 auf, welcher einen zur Führung bei seiner Hubbewegung dienenden Bolzen 41 umgreift. Zum Antreiben des Stössels 24 dient ein in einem Kolbengehäuse 42 gelagerter, pneumatisch antreibbarer Kolben 43.4 shows the arrangement of the likewise pneumatically operable plunger 24, which is not shown in FIG. 3 for the sake of clarity. The plunger 24 is arranged on the inside of the two separation stages, that is, below the upper and above the lower separation stage SP. According to the illustration, the longitudinal axis of the essentially prismatic plunger 24 lies obliquely to the feed direction A of the strands LI and its end face contacting the strands LI runs accordingly obliquely to the longitudinal axis, or in other words, parallel to the longitudinal axis of the compartment member 21 (arrow C). The plunger 24 has a longitudinal slot 40 which engages around a bolt 41 which serves to guide it during its lifting movement. A piston 43, which is pneumatically driven and is mounted in a piston housing 42, is used to drive the plunger 24.

Die beschriebene Vorrichtung zum Vereinzeln der Litzen ist vorzugsweise so ausgebildet, dass die gesamte Einrichtung, das heisst, die Separierstufe mitsamt den Litzentragschienen und dem Transportmittel für die Zuführung der Litzen auf einen gemeinsamen Grundgestell montiert ist. Dieses Grundgestell ist fahrbar ausgeführt und kann somit auf einfache Weise in die Kettfadeneinziehmaschine hineingefahren werden. Zwischen der Vorrichtung zum Vereinzeln der Litzen und der nachfolgenden Transporteinheit für den Transport der Litzen an ihre Einziehposition besteht eine lösbare Verbindung, in Form einer Rastkupplung. Die verschiedenen Funktionen der einzelnen Teile wie Abteilorgan 21, Stössel 24, Schwenkhebel 37 sind getrennt gesteuert, die Synchronisierung der verschiedenen Funktionsabläufe erfolgt über den Modulrechner des Litzenmoduls.The device described for separating the strands is preferably designed such that the entire device, that is to say the separating step, together with the strand support rails and the transport means for feeding the strands, is mounted on a common base frame. This base frame is designed to be mobile and can therefore be easily inserted into the Warp threading machine can be driven in. There is a releasable connection, in the form of a locking coupling, between the device for separating the strands and the subsequent transport unit for transporting the strands to their retracted position. The various functions of the individual parts such as compartment member 21, plunger 24, swivel lever 37 are controlled separately, the various functional sequences are synchronized via the module computer of the stranded module.
