Description

Die Erfindung betrifft eine Vorrichtung Zum Kuppeln eines Schaftzuges bzw. einer Schaftmaschine einer Webmaschine mit einem Webschaftrahmen, wobei insbesondere seitliche Führungen für den Webschaftrahmen vorgesehen sind und der Schaftzug über Winkelhebel mit der Schaftmaschine verbunden ist.The invention relates to a device for coupling a heald frame or a loom of a loom with a heald frame, in particular lateral guides for the heald frame are provided and the heald frame is connected to the dobby by angle levers.

Aus der DE-A-3 036 419 ist eine Vorrichtung zum Kuppeln eines Schaftzuges mit einem Webschaftrahmen bekannt, bei der das kuppelnde Ende des Schaftzugs als Haken mit einem Maul zur Aufnahme eines entsprechend geformten Gegenstücks des Webschaftrahmens ausgebildet ist. Der Schaftzughaken ist mit einer an das Maul anschließenden Auflage zum Abstützen des Gegenstücks versehen und in einer ersten Schwenkstellung fixierbar, in welcher das Gegenstück frei auf die Auflage abgesenkt werden kann. Ferner ist jeder der beiden Reihen von Schaftzügen je ein Justier- und ein Verstellorgan zugeordnet. Nachteilig hierbei ist, daß die Vorrichtung einen verhältnismäßig komplizierten Mechanismus besitzt und beim Kupplungsvorgang Manipulationen erforderlich sind, welche zur Automatisierung ungeeignet sind.From DE-A-3 036 419 a device for coupling a heald frame with a heald frame is known, in which the coupling end of the heald frame is designed as a hook with a mouth for receiving a correspondingly shaped counterpart of the heald frame. The shaft pulling hook is provided with a support adjoining the mouth for supporting the counterpart and can be fixed in a first swivel position in which the counterpart can be lowered freely onto the support. Furthermore, each of the two rows of shaft pulls is assigned an adjusting and an adjusting member. The disadvantage here is that the device has a relatively complicated mechanism and manipulations are required during the coupling process, which are unsuitable for automation.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, die nicht nur einfach und betriebssicher, sondern auch für automatisierten Betrieb, insbesondere mit Robotern, geeignet ist.The object of the invention is to provide a device of the type mentioned at the outset, which is not only simple and reliable, but also suitable for automated operation, in particular with robots.

Diese Aufgabe wird gelöst durch eine Kupplungshülse mit einem Hohlraum zur Aufnahme eines Kupplungsglieds, wobei der Hohlraum wenigstens einen zahnartigen Vorsprung aufweist, welcher bei fluchtender Stellung und Vereinigung von Kupplungshülse und Kupplungsglied in eine entsprechende Ausnehmung des Kupplungsglieds einrastet, und ferner der Hohlraum gegenüber dem jeweiligen Vorsprung eine Erweiterung aufweist derart, daß eine relative Verschwenkung von Kupplungshülse und Kupplungsglied zwecks Ausrasten des zahnartigen Vorsprungs und Lösen der Kupplung gewährleistet ist.This object is achieved by a coupling sleeve with a cavity for receiving a coupling member, the cavity having at least one tooth-like projection, which engages in a corresponding recess of the coupling member when the coupling sleeve and coupling member are in alignment and union, and furthermore the cavity opposite the respective projection an extension has such that a relative pivoting of the coupling sleeve and coupling member is ensured in order to disengage the tooth-like projection and release the coupling.

Hierdurch läßt sich erreichen, daß die Kupplung lediglich durch seitliche Verschwenkung z.B. der Schaftzüge in eine Position gebracht werden kann, welche ein Lösen der Kupplung bzw. ein Herausziehen des Webschaftrahmens ermöglicht. Somit kann auf bewegliche Teile wie Riegel, Verstellhaken etc. verzichtet werden. Die eigentliche Kupplung besteht nur noch aus zwei ineinandergreifenden beweglichen Komponenten. Dadurch wird auch auf einfache Weise der Einsatz von Robotern möglich, indem z.B. mit entsprechenden Greifern der Webschaftrahmen bzw. ein ganzes Schaftpaket ausgewechselt werden kann.In this way it can be achieved that the coupling only by lateral pivoting e.g. the shaft pulls can be brought into a position which enables the coupling to be released or the heald frame to be pulled out. Moving parts such as bolts, adjustment hooks etc. can thus be dispensed with. The actual coupling only consists of two interlocking moving components. This also makes the use of robots possible in a simple manner, for example by With appropriate grippers the heald frame or an entire shaft package can be replaced.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention can be found in the following description and the subclaims.

Bei der in Fig. 1 dargestellten Webmaschine 10 sind an den Seitenwänden 11, 12 seitlich verschiebbare Führungen 14, 16 vorgesehen, in denen Webschäfte 18 (nur der vorderste mit Bezugsziffer versehen) in vertikaler Richtung verschiebbar geführt sind. Zum Antrieb der Webschäfte 18 dient eine mit der einen Seitenwand 11 verbundene Schaftmaschine 20. Jede Schaftzwinge 22 der Schaftmaschine 20 ist über einen Antriebshebel 24 und verschiedene, den Schaftzug bildende Winkelhebel 26, 28 und Stoßoder Zugstangen 30 mit Schaftzugstangen 32, 34 verbunden, die in bekannter Weise teleskopartig längsverstellbar sind.In the weaving machine 10 shown in FIG. 1, laterally displaceable guides 14, 16 are provided on the side walls 11, 12, in which heald frames 18 (only the first one provided with the reference number) are guided so as to be displaceable in the vertical direction. A heald frame 20 connected to the one side wall 11 is used to drive the heald frames 18. Each shaft clamp 22 of the heald frame 20 is connected via a drive lever 24 and various angle levers 26, 28 and push or pull rods 30 with shaft pull rods 32, 34, which in FIG are known telescopically longitudinally adjustable.

Gemäß Fig. 2a, 2b ist an jeder Schaftzugstange 32,34 eine Kupplungshülse 36,38 mit im wesentlichen rechteckigen Querschnitt angeordnet, die einen Hohlraum 40 zur Aufnahme eines am Schaftrahmen 42 befestigten Kuppungsglieds 44, 46 aufweist.2a, 2b, a coupling sleeve 36, 38 with an essentially rectangular cross section is arranged on each shaft pull rod 32, 34, which has a cavity 40 for receiving a coupling member 44, 46 fastened to the shaft frame 42.

Darstellungsgemäß weist jeder Schaftrahmen 42 je zwei Kupplungsglieder 44, 46 auf. Dementsprechend sind pro Webschaft 18 je zwei Schaftzugstangen 32, 34 vorgesehen. Selbstverständlich kann die Anzahl der Schaftzugstangen 32, 34 pro Webschaft 18 variieren; bei sehr schmalen Webmaschinen, z.B. Bandwebmaschinen, genügt eine Schaftzustange pro Webschaft 18, bei breiten Webmaschinen können gegebenenfalls drei oder mehr Schaftzugstangen 32, 34 pro Webschaft 18 vorgesehen sein.As shown, each shaft frame 42 has two coupling members 44, 46. Accordingly, two shaft pull rods 32, 34 are provided per heald frame 18. Of course, the number of shaft drawbars 32, 34 per heald frame 18 can vary; with very narrow weaving machines, e.g. Ribbon looms, one shaft feed per heald frame 18 is sufficient; in the case of wide looms, three or more shaft drawbars 32, 34 can be provided per heald frame 18.

Dabei weist der Hohlraum 40 zwei zahnartige Vorsprüngen 48, 50 auf, welche bei fluchtender Stellung und Vereinigung von Kupplungshülse 36 und Kupplungsglied 44 in entsprechende Ausnehmungen 52, 54 des Kupplungsglieds 44 einrasten. Ferner weist der Hohlraum 40 gegenüber dem jeweiligen Vorsprung 48, 50 eine etwa keilförmige Erweiterung 56, 58 auf. Der Boden 60 der Kupplungshülse 36 ist als Gleitbahn mit zylindrischer Mantelfläche ausgebildet, auf der eine entsprechend ausgebildete Gleitfläche 62 des Kupplungsglieds 44 abgestützt ist.The cavity 40 has two tooth-like projections 48, 50 which engage in corresponding recesses 52, 54 of the coupling member 44 when the coupling sleeve 36 and coupling member 44 are in alignment. Furthermore, the cavity 40 has an approximately wedge-shaped extension 56, 58 relative to the respective projection 48, 50. The bottom 60 of the coupling sleeve 36 is designed as a slideway with a cylindrical outer surface on which a correspondingly designed sliding surface 62 of the coupling member 44 is supported.

Beim Betriebsbeispiel nach Fig. 3a bis 3c befinden sich gemäß Fig. 3a die Winkelhebel 28 etwa in einer der mittleren Stellung des Webschaftrahmens entsprechender Position M, wobei sich die Schaftzugstangen 32, 34 in vertikaler Lage befinden. Dabei ist der obere Totpunkt des Winkelhebels 26, 28 mit A, der untere mit 8 bezeichnet. Neben den Schaftzugstangen 32, 34 sind rillenartige Seitenanschläge 64, 66 angeordnet, welche gemäß der vergrößerten Detaildarstellung von Fig. 3b für jede Schaftzugstange eine Rille 68 aufweisen.In the operating example according to FIGS. 3a to 3c, according to FIG. 3a the angle levers 28 are approximately in a position M corresponding to the middle position of the heald frame, the shaft pull rods 32, 34 being in a vertical position. The top dead center of the bell crank 26, 28 is designated A, the bottom 8. In addition to the shaft pull rods 32, 34, groove-like side stops 64, 66 are arranged, which according to the enlarged detailed illustration of FIG. 3b have a groove 68 for each shaft pull rod.

Nun werden die seitlichen Führungen 14, 16 in Richtung des Pfeils 70 nach rechts um den Abstand L verschoben, wobei die Schaftzugstangen 32,34 um den Winkel a (Fig. 3c, 4, 7a, 8) nach rechts verschwenkt und die einzelnen Schaftzugstangen 32,34 in den Rillen 68 abgestützt werden. Wie aus Fig. 4 ersichtlich ist, werden dabei die zahnartigen Vorsprünge 48, 50 aus den Ausnehmungen 52 bzw. 54 ausgerastet, indem das Kupplungsglied 44 gegen die Anschlagflächen der Erweiterungen 56, 58 bewegt wird, wobei die Gleitfläche 62 des Kupplungsglieds 44 entlang dem Boden 60 der Kupplungshülse 36 gleitet. In dieser Lage kann die entsicherte Kupplung gelöst und der Schaftrahmen 42 bzw. das ganze Schaftpaket gemäß Pfeil 72 (Fig. 3c, 4) herausgehoben werden.The lateral guides 14, 16 are now shifted to the right by the distance L in the direction of the arrow 70, the shaft pull rods 32, 34 being pivoted to the right by the angle a (FIGS. 3 c, 4, 7 a, 8) and the individual shaft pull rods 32 , 34 are supported in the grooves 68. 4, the tooth-like projections 48, 50 are disengaged from the recesses 52 and 54, respectively, by moving the coupling member 44 against the abutment surfaces of the extensions 56, 58, the sliding surface 62 of the coupling member 44 along the floor 60 of the coupling sleeve 36 slides. In this position, the unlocked coupling can be released and the shaft frame 42 or the entire shaft package can be lifted out according to arrow 72 (FIGS. 3c, 4).

Der neue Schaftrahmen bzw. das neue Schaftpaket wird gemäß Pfeil 74 wieder eingesetzt und die Kupplung durch Rückverschieben der Führungen 14, 16 nach links bzw. Verschwenken der Schaftzugstangen 32, 34 nach links wieder geschlossen.The new shaft frame or the new shaft package is reinserted according to arrow 74 and the coupling is closed again by moving the guides 14, 16 back to the left or pivoting the shaft pull rods 32, 34 to the left.

Beim Ausführungsbeispiel nach Fig. 6a, 6b werden lediglich die Winkelhebel 26, 28 durch Betätigung der Antriebshebel 24 gemäß Pfeil 76 über ihre obere Totpunktlage A hinaus bis zur Stellung C verschwenkt, wodurch der erforderliche Schwenkwinkel a zur Lösung der Kupplung erzeugt wird, ohne daß die seitlichen Führungen 14, 16 verschoben werden müssen. Hierdurch vereinfacht sich der Betrieb, und die Vorrichtung eignet sich insbesondere für vollautomatischen Schaftpaketwechsel z.B. mit Roboter-Greifern 78, 80, welche durch einen hydraulischen oder pneumatischen Schwenkantrieb 82 betätigt werden. Dieser kann über Signalleitungen 79, 81 und eine Steuereinrichtung 83 mit der Schaftmaschine 20 verbunden sein.In the embodiment of Fig. 6a, 6b only the angle lever 26, 28 are pivoted by actuating the drive lever 24 according to arrow 76 beyond their top dead center position A to position C, whereby the required pivot angle a is generated to release the clutch without the lateral guides 14, 16 must be moved. This simplifies operation and the device is particularly suitable for fully automatic shaft pack changes, e.g. with robot grippers 78, 80, which are actuated by a hydraulic or pneumatic swivel drive 82. This can be connected to the dobby 20 via signal lines 79, 81 and a control device 83.

Bei der Variante nach Fig. 7a ist das Kupplungsglied 44 über einen Flansch 84 mittels Schrauben 86, 88 am Webschaftrahmen 42 angeschraubt. Die obere Erweiterung 56 ist durch ein an der Schraube 86 befestigtes federndes Schließblech 90 verschlossen zwecks Abweisung von Fadenflug, welcher sich sonst in der Erweiterung 56 ansammeln und die Schwenkbewegung zwischen Kupplungsglied 44 und Kupplungshülse 36 behindern könnte. Da das Schließblech 90 federnd ist, behindert es die Schwenkbewegung nicht.In the variant according to FIG. 7 a, the coupling member 44 is screwed onto the heald frame 42 via a flange 84 by means of screws 86, 88. The upper extension 56 is closed by a resilient striking plate 90 fastened to the screw 86 for the purpose of rejecting thread flight, which would otherwise accumulate in the extension 56 and could hinder the pivoting movement between the coupling member 44 and the coupling sleeve 36. Since the striking plate 90 is resilient, it does not hinder the pivoting movement.

Bei der Variante nach Fig. 8 ist das Kupplungsglied 44 über eine an sich bekannte elastische Torsionskupplung 92 mit einer Gummibüchse 94 im Webschaftrahmen 42 befestigt. Hierbei ergibt sich der Vorteil einer leichten Einrastung, ohne daß allzu hohe Toleranzgrenzen in Bezug auf die Achsparallelität von Kupplungshülse 36 und Kupplungsglied 44 eingehalten werden müssen. Wie ferner aus Fig. 8 hervorgeht, ist die Flanke 49 bzw. 51 des jeweiligen zahnartigen Vorsprungs 48 bzw. 50 so gekrümmt, daß beim Einrasten eine keilartige Verspannung gewährleistet ist.In the variant according to FIG. 8, the coupling member 44 is fastened in the heald frame 42 via a known elastic torsion coupling 92 with a rubber bushing 94. This results in the advantage of a slight engagement, without having to maintain excessively high tolerance limits with respect to the parallelism of the coupling sleeve 36 and coupling member 44. As can further be seen from FIG. 8, the flank 49 or 51 of the respective tooth-like projection 48 or 50 is curved in such a way that a wedge-like bracing is ensured when it engages.

Anstatt zwischen Schaftzug 24, 26, 32 und Webschaftrahmen 42 kann die' erfindungsgemäße Kupplungsvorrichtung 36, 44 auch zwischen Schaftmaschine 20 und Schaftzug z.B. am Ort der Schaftschwinge 22 angebracht und in der beschriebenen Weise betätigt werden.Instead between Schaftzug 24, 26, 32 and heald frame 42, the 'coupling device according to the invention 36, 44 and between 20 and Schaftzug dobby for example mounted at the location of the shaft crank 22 and are actuated in the manner described.
