Description

Die Erfindung betrifft eine Webschaftkupplung und eine Vorrichtung zum simultanen Öffnen und Schließen einer Vielzahl von Webschaftkupplungen in einer Webmaschine.
Jede Webschaftkupplung besteht bekanntermaßen aus einem oder mehreren schaftseitigen Kupplungselementen und aus einem oder mehreren antriebsseitigen Kupplungselementen, die im gekuppelten Zustand formschlüssig ineinander greifen und eine Wirkverbindung zwischen den Webschäften und den zugehörigen Antriebsorganen herstellen.The invention relates to a heald frame coupling and a device for simultaneously opening and closing a plurality of heald frame couplings in a weaving machine.
Each heald frame coupling is known to consist of one or more shaft-side coupling elements and one or more drive-side coupling elements which engage in a form-fitting manner in the coupled state and produce an operative connection between the heald frames and the associated drive elements.

Bekannte Webschaftkupplungen bedingen zum Kuppeln und Entkuppeln der Webschäfte mit bzw. von den Antriebsorganen Betätigungswerkzeuge, mit denen jede einzelne Wirkverbindung zwischen dem Webschaft und dem Antriebsorgan separat aufgehoben wird.
Derartige Schaftkupplungsvorgänge erfordern im Vorfeld des Webprozesses, d.h. beim Webgeschirrwechsel einen erheblichen Zeitaufwand in den Webereien. Zur Reduzierung der beim Webgeschirrwechsel anfallenden zeitaufwendigen Kupplungs- und Entkupplungsvorgänge ist aus der EP 0 407 335 eine Webschaftkupplung in Kombination mit einer Vorrichtung zum simultanen Öffnen und Schließen einer Vielzahl von Webschaftkupplungen bekannt.
Danach können die speziell ausgebildeten Webschaftkupplungen, nachdem die Webschäfte in die sogenannte Schaftgleichstellung gebracht worden sind, von einem maschinenfest angeordneten Betätigungswerkzeug, das einzelne oder die Gesamtheit der Schaftkupplungen umgreift und das nach einer rotatorischen Verstellung eine Spannkraft auf die antriebsseitigen Webschaftkupplungen aufbringt, simultan entkuppelt oder gekuppelt werden.Known heald frame couplings require actuating tools for coupling and uncoupling the heald frames with or from the drive elements with which each individual operative connection between the heald frame and the drive element is released separately.
Such shaft coupling operations require a considerable amount of time in the weaving mills in advance of the weaving process, ie when changing the harness. EP 0 407 335 discloses a heald frame coupling in combination with a device for simultaneous opening and closing of a large number of heald frame couplings to reduce the time-consuming coupling and uncoupling processes involved in changing the harness.
After that, the specially designed heald frame couplings, after the heald frames have been brought into the so-called shaft alignment, can be simultaneously decoupled or coupled by an actuating tool which is fixed to the machine and which engages around individual or all of the shaft couplings and which, after a rotary adjustment, applies a tension force to the drive-side heald frame couplings become.

Derartige Webschaftkupplungen erfordern sowohl für das antriebsseitige als auch für das schaftseitige Kupplungsteil aufgrund der geometrischen Form und der Vielzahl der die Zug- und Stoßkräfte übertragenden Flächen einen relativ hohen Fertigungsaufwand.Such heald frame couplings require a relatively high production outlay both for the drive-side and for the shaft-side coupling part due to the geometric shape and the large number of surfaces that transmit the tensile and impact forces.

Aufgabe der Erfindung ist es, eine Schaftkupplung zu schaffen, deren Kupplungsteile eine einfache geometrische Ausbildung aufweisen und einen geringen Fertigungsaufwand erfordern.
Es ist ferner Aufgabe der Erfindung auf ein einzelnes zusätzliches Sicherungselement, wie es die bekannte Schaftkupplung nach der europäischen Patentanmeldung 0 407 335 erfordert, zu verzichten und vielmehr die Verriegelung der Kupplung in die Gesamtlösung zu integrieren.
Des weiteren ist es Aufgabe der Erfindung, in Kombination mit jeder einzelnen Schaftkupplung eine Vorrichtung zum simultanen Kuppeln und Entkuppeln zu schaffen, die außerhalb des Bewegungsbereichs der Schäfte und ihrer Antriebe angeordnet ist und die im Falle eines Schaftwechsels die Schaftzug- bzw. -schubstange in der für den Kupplungsvorgang erforderlichen Wartestellung hält.The object of the invention is to provide a shaft coupling, the coupling parts of which have a simple geometric design and require little production effort.
It is a further object of the invention to dispense with a single additional securing element, as required by the known shaft coupling according to European patent application 0 407 335, and rather to integrate the locking of the coupling into the overall solution.
Furthermore, it is an object of the invention to provide, in combination with each individual shaft coupling, a device for simultaneous coupling and uncoupling which is arranged outside the range of movement of the shafts and their drives and which, in the event of a shaft change, the shaft pulling or pushing rod in the holding position required for the coupling process.

Die Aufgabenstellungen werden gemäß der Merkmale des Anspruchs 1 und gemäß der Merkmale des unabhängigen Anspruchs 6 gelöst.
Die wesentlichen Vorteile der erfindungsgemäßen Lösung bestehen darin, daß die einzelnen Kupplungsteile eine einfache geometrische Form aufweisen und daher keiner aufwendigen Fertigung bedürfen, daß auf eine separate Sicherungseinrichtung gegen selbstständiges Öffnen der Kupplung verzichtet werden kann und daß die das simultane Kuppeln und Entkuppeln bewerkstelligende Vorrichtung außerhalb des Bewegungsbereichs von Schaft und Schaftzug angeordnet ist und damit dem im Bereich der Webmaschine auftretenden Faserflug nicht direkt ausgesetzt ist.The problems are solved according to the features of claim 1 and according to the features of independent claim 6.
The main advantages of the solution according to the invention are that the individual coupling parts have a simple geometric shape and therefore do not require complex production, that there is no need for a separate securing device to prevent the clutch from opening independently, and that the device which accomplishes the simultaneous coupling and uncoupling is outside the device Movement range of the shaft and shaft pull is arranged and thus is not directly exposed to the fiber fly occurring in the area of the weaving machine.

Wie Figur 1 zeigt, ist ein Träger 1, ähnlich einem Lagerbock ausgebildet, über die symbolhaft dargestellten Schrauben 2 mit dem andeutungsweise dargestellten Webschaft 3 verbunden. Von dem Träger 1 wird das um die Trägerachse 4 drehbeweglich gelagerte schaftseitige Kupplungsteil 5 aufgenommen. Das in Art eines Schließkeils ausgebildete Kupplungsteil 5 besitzt, wie Figur 2 zeigt, zu beiden Seiten seiner Längsachse 6 jeweils eine in horizontaler Ebene verlaufende Stützfläche 7 bzw. 8, die im gekuppelten Zustand mit entsprechenden Gegenstützflächen 9,10 des antriebsseitigen Kupplungsteil 11 in Kontakt stehen. Dadurch ist die vertikale Bewegung der beiden ineinander greifenden Kupplungsteile 5,11 begrenzt.As FIG. 1 shows, a carrier 1, similar to a bearing block, is connected to the heald frame 3, which is indicated by way of illustration, by means of the symbolically represented screws 2. The shaft-side coupling part 5 mounted rotatably about the carrier axis 4 is received by the carrier 1. The coupling part 5 designed in the manner of a locking wedge, as shown in FIG. 2, has on both sides of its longitudinal axis 6 a supporting surface 7 or 8 running in a horizontal plane, which in the coupled state are in contact with corresponding counter-supporting surfaces 9, 10 of the drive-side coupling part 11 . This limits the vertical movement of the two interlocking coupling parts 5, 11.

Während die Stützfläche 8 aus ihrem horizontalen Verlauf in eine parallel zur Längsachse 6 des Kupplungsteils 5 verlaufende rechte Anlagefläche 12 übergeht, geht die Stützfläche 7 in eine zunächst spitzwinklig zur Längsachse 6 des Kupplungsteils 5 verlaufende Anlagefläche 13 über, die im Endbereich des Kupplungsteils 5 eine schräg zur o.g. Längsachse 6 verlaufende Stützfläche 13a für eine Klinke 14 ausbildet.
Das antriebsseitige Kupplungsteil 11 besteht aus einem ersten und einem zweiten mit der Schub-Zugstange 15 verbindbaren Lagerkörper 16,17 mit den vorstehend erwähnten Stützflächen 9 bzw. 10, siehe auch Fig. 3.
Zwischen diesen Lagerkörpern 16,17 sind die mit dem Kupplungsteil 5 zusammenwirkenden antriebsseitigen Kupplungselemente angeordnet, wie ein mit der Anlagefläche 12 des Kupplungsteils 5 zur Anlage kommendes Anlagestück 18 und eine schwenkbar um die Achse 19 gelagerte und mit einem Gelenkmechanismus 20 in Verbindung stehende Klinke 14, deren Stützfläche 14a mit der Stützfläche 13a des Kupplungsteils 5 zur Anlage kommt, sieh auch Fig. 2.While the support surface 8 merges from its horizontal course into a right contact surface 12 running parallel to the longitudinal axis 6 of the coupling part 5, the support surface 7 merges into a contact surface 13 which initially runs at an acute angle to the longitudinal axis 6 of the coupling part 5 and which is inclined in the end region of the coupling part 5 to the above longitudinal axis 6 extending support surface 13a for a pawl 14.
The drive-side coupling part 11 consists of a first and a second bearing body 16, 17 which can be connected to the push-pull rod 15 and has the abovementioned support surfaces 9 and 10, see also FIG. 3.
Arranged between these bearing bodies 16, 17 are the drive-side coupling elements which cooperate with the coupling part 5, such as a contact piece 18 which comes into contact with the contact surface 12 of the coupling part 5 and a pawl 14 which is pivotably mounted about the axis 19 and is connected to a joint mechanism 20, whose support surface 14a comes into contact with the support surface 13a of the coupling part 5, see also FIG. 2.

Durch die Zugfeder 22, die innerhalb des antriebsseitigen Kupplungsteils 11 einerseits an einer Federachse 21 und andererseits an dem Gelenkmechanismus 20 mit Federachse 24 angreift, wird aufgrund einer entsprechenden Festlegung des Schwenkpunktes 23 für den Dreieckhebel 25 des Gelenkmechanismus 20 und für die Federachse 24 der Zugfeder 22 am Gelenkmechanismus 20, ein selbstständiges Lösen der Kupplungsteile 5,11 ausgeschlossen.
Die erfindungsgemäß ausgebildete Schaftkupplung 5,11 verzichtet damit, im Gegensatz zu der bekannten Lösung, auf eine zusätzliche Verriegelungseinrichtung.The tension spring 22, which acts on the one hand on the spring-side coupling part 11 on a spring axis 21 and on the other hand on the joint mechanism 20 with spring axis 24, is due to a corresponding determination of the pivot point 23 for the triangular lever 25 of the joint mechanism 20 and for the spring axis 24 of the tension spring 22 on the joint mechanism 20, an independent loosening of the coupling parts 5, 11 is excluded.
In contrast to the known solution, the shaft coupling 5, 11 designed according to the invention therefore dispenses with an additional locking device.

Der mit der Klinke 14 über den Schwenkpunkt 23 in Verbindung stehende Gelenkmechanismus 20 besteht beispielsweise aus einem Dreieckhebel 25 mit jeweils einem in den Eckbereichen vorhandenen Schwenk- bzw. Anlenkpunkt 23,24,26. Die einzelnen imaginären Verbindungslinien zu dem Schwenkpunkt 23 und zu den Anlenkpunkten 24,26 bilden ein gleichschenkliges Dreieck.The articulated mechanism 20, which is connected to the pawl 14 via the pivot point 23, consists, for example, of a triangular lever 25, each with a pivot or pivot point 23, 24, 26 in the corner regions. The individual imaginary connecting lines to the pivot point 23 and to the articulation points 24, 26 form an isosceles triangle.

Der Schwenkpunkt 23 bildet die drehbewegliche Verbindung zwischen der Klinke 14 und dem Gelenkmechanismus 20, respektive dem Dreieckhebel 25.
Ein zweiter Anlenkpunkt wird von der Federachse 24 gebildet. Den dritten Anlenkpunkt bildet die Achswelle 26a, an welcher der im antriebsseitigen Kupplungsteil 11 um die Achswelle 27 schwenkbare Winkelhebel 28 angreift.
Der Hebelarm 28a des Winkelnebels 28 ist gelenkig über die Achswelle 26a mit dem Dreieckhebel 25 verbunden.
Der Hebelarm 28b trägt an seinem freien Ende z.B. eine von einer Rollenachse 29 getragene Rolle 30, die zum Zwecke des Kuppelns und Entkuppelns mit einer Betätigungsvorrichtung 31 in Wirkverbindung bringbar ist.The pivot point 23 forms the rotatable connection between the pawl 14 and the articulated mechanism 20 or the triangular lever 25.
A second articulation point is formed by the spring axis 24. The third articulation point is formed by the axle shaft 26a, on which the angle lever 28 pivotable about the axle shaft 27 in the drive-side coupling part 11 engages.
The lever arm 28a of the angle fog 28 is articulatedly connected to the triangular lever 25 via the axle shaft 26a.
At its free end, the lever arm 28b carries, for example, a roller 30 carried by a roller axis 29, which roller can be operatively connected to an actuating device 31 for the purpose of coupling and uncoupling.

In Figur 2 ist das schaftseitige Kupplungsteil 5 von dem antriebsseitigen Kupplungsteil 11 getrennt; die Klinke 14 wurde dazu durch Betätigung des Gelenkmechanismus 20 im Sinne eines Spannens der Zugfeder 22 außer Eingriff vom Kupplungsteil 5 gebracht.
Bei Betätigung des Winkelhebels 28 erfolgt mit der erfindungsgemäß ausgebildeten Vorrichtung 31 das simultane Kuppeln bzw. Entkuppeln aller Webschäfte 3 von ihrem antriebsseitigen Kupplungsteil 11, das mit der jeweiligen Schub- bzw. Zugstange 15 verbunden ist.In Figure 2, the shaft-side coupling part 5 is separated from the drive-side coupling part 11; the pawl 14 was brought out of engagement by the coupling part 5 by actuating the joint mechanism 20 in the sense of tensioning the tension spring 22.
When the angle lever 28 is actuated, the device 31 designed according to the invention simultaneously couples or uncouples all heald frames 3 from their drive-side coupling part 11, which is connected to the respective push rod 15.

Die Vorrichtung 31 besteht aus einer drehbar in einem nicht dargestellten Webmaschinenteil gelagerten Stellwelle 31a, mit welcher eine Vielzahl von Betätigungselementen 31b nacheinander drehfest verbunden ist. Jedes der Betätigungselemente 31b ist so ausgelegt, daß bei vollständig entriegeltem Kupplungsteil 5 zwischen dem Betätigungselement 31b und dem Winkelhebel 28 eine formschlüssige Verbindung hergestellt ist. Dazu weist das Betätigungselement 31b eine die Rolle 30 erfassende Kontaktfläche 32 auf, die in eine als Kurve 33 ausgebildete Führung mit Endbegrenzung übergeht.The device 31 consists of an adjusting shaft 31a rotatably mounted in a weaving machine part, not shown, to which a plurality of actuating elements 31b are successively connected in a rotationally fixed manner. Each of the actuating elements 31b is designed in such a way that when the coupling part 5 is completely unlocked, a positive connection is established between the actuating element 31b and the angle lever 28. For this purpose, the actuating element 31b has a contact surface 32 which grips the roller 30 and which merges into a guide designed as a curve 33 with an end limitation.

In dieser Kurve ruht die Rolle 30 im entkuppelten Zustand der Webschaftkupplung z.B. während des Webgeschirrwechsels.
Nach dem Einsetzen des schaftseitigen Kupplungsteil 5 in das antriebsseitige Kupplungsteil 11 wird die formschlüssige Verbindung zwischen dem Betätigungselement 31b und der Rolle 30 durch Zurückschwenken des Betätigungselements 31b in Pfeilrichtung "schließen" aufgehoben; die Klinke 14 wird automatisch unter Wirkung der Zugkraft der Zugfeder 22 in die Ausnehmung des durch das Anlagestück 18 und einem Punkt 14b am Umfang des Klinkenkopfes der Klinke 14 vorzentrierten Kupplungsteils 5 eingeschwenkt, siehe auch Figur 1.
Die Art und Weise des Antriebes der Stellwelle 31a und die Steuerung ihres Antriebs kann dem Fachmann überlassen bleiben.In this curve, the roller 30 rests in the uncoupled state of the heald frame coupling, for example during the change of the harness.
After inserting the shaft-side coupling part 5 into the drive-side coupling part 11, the positive connection between the actuating element 31b and the roller 30 is canceled by pivoting the actuating element 31b back in the direction of the arrow; the pawl 14 is automatically pivoted under the action of the tensile force of the tension spring 22 into the recess of the coupling part 5 precentered by the contact piece 18 and a point 14b on the circumference of the pawl head of the pawl 14, see also FIG. 1.
The manner in which the actuating shaft 31a is driven and the control of its drive can be left to the person skilled in the art.

Figur 3 zeigt die schaftseitigen und antriebsseitigen Kupplungsteile 5 bzw. 11 dicht aneinander liegend in Art eines Paketes ausgebildet.
Die schaftseitigen Kupplungsteile 5 sind hier von den antriebsseitigen Kupplungsteilen 11 getrennt dargestellt.
Die Stellwelle 31a ist als Vielkeilwelle ausgebildet; sie durchdringt die Betätigungselemente 31b, die damit drehfest auf der Stellwelle 31a sitzen.
Durch eine Drehbewegung der Stellwelle 31a in die angegebenen Pfeilrichtungen "Öffnen" bzw. "Schließen" werden die einzelnen Betätigungselemente 31b simultan außer Wirkverbindung oder in Wirkverbindung mit dem jeweiligen Hebel 28 der einzelnen Gelenkmechanismen 20 gebracht, wie in Figur 1 und 2 dargestellt.
Damit können alle Schaftkupplungen entweder gleichzeitig geöffnet oder gleichzeitig geschlossen werden.FIG. 3 shows the shaft-side and drive-side coupling parts 5 and 11, which are arranged close to one another in the manner of a package.
The shaft-side coupling parts 5 are shown here separately from the drive-side coupling parts 11.
The adjusting shaft 31a is designed as a splined shaft; it penetrates the actuating elements 31b, which thus sit on the actuating shaft 31a in a rotationally fixed manner.
By rotating the actuating shaft 31a in the indicated arrow directions “opening” or “closing”, the individual actuating elements 31b are simultaneously brought out of operative connection or in operative connection with the respective lever 28 of the individual joint mechanisms 20, as shown in FIGS. 1 and 2.
This means that all shaft couplings can either be opened simultaneously or closed simultaneously.
