Description

Die Erfindung betrifft eine Hebelitze einer Dreherbindungsvorrichtung mit einer Klemmvorrichtung zur Bereitstellung einer Klemmverbindung als lösbare Verbindung von einer Harnischschnur mit der Hebelitze gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lifting heald of a leno binding device with a clamping device for providing a clamping connection as a detachable connection between a harness cord and the lifting heald according to the preamble of claim 1.

Die DE 199 15 815 C1 beschreibt eine Hebelitze zur Bildung einer Dreherkante. Die Hebelitze weist endseitig jeweils einen Einhängehaken zur Aufnahme durch die Litzentragschiene auf. Der Einhängehaken ist verschwenkbar an der Hebelitze angeordnet, wobei Sicherungsmittel zur Fixierung des Einhängehakens in an der Litzentragschiene eingehängten Position vorgesehen sind.The DE 199 15 815 C1 describes a lifting heald to form a leno edge. Each end of the lifting heald has a hanging hook for receiving it by the heald support rail. The suspension hook is pivotably arranged on the lifting heald, with securing means for Fixing of the suspension hook in the suspended position on the heddle support rail are provided.

Eine Dreherbindungsvorrichtung ist aus dem Stand der Technik auch für Jacquard-Maschinen hinlänglich bekannt. So ist beispielsweise in der EP 2 236 655 eine solche Dreherbindungsvorrichtung für eine Jacquard-Maschine beschrieben, die zwei Hebelitzen umfasst, sowie eine wechselweise von diesen Hebelitzen mitgenommenen Halblitze. Aus dieser Literaturstelle ist auch eine Befestigung der Harnischschnüre an den Hebelitzen erkennbar, nämlich der Gestalt, dass die Hebelitzen am oberen Ende eine Öse aufweisen, wobei die Harnischschnüre mit der Öse durch einen üblichen Weberknoten verbunden sind.A leno binding device is well known from the prior art for jacquard machines. For example, in the EP 2 236 655 such a leno tying device for a jacquard machine is described, which comprises two lifting healds and a half heald alternately carried along by these lifting healds. From this reference, an attachment of the harness cords to the lifting healds can also be seen, namely in the form that the lifting healds have an eyelet at the upper end, the harness cords being connected to the eyelet by a conventional weaver knot.

Aus der EP 0 915 195 B1 ist eine Klemmvorrichtung der eingangs genannten Art bekannt, bei der die Harnischschnur in Form einer Schlaufe durch eine obere Klemmöffnung eines elastischen Kuppelgliedes geführt ist, wobei das Kuppelglied Teil der Hebelitze ist. Die beiden Enden mit der Schlaufe der Harnischschnur werden durch eine Metallhülse gefädelt, welche über das Kuppelglied zur Aufrechterhaltung einer Klemmverbindung geschoben wird. Die Regulierung der Länge der Harnischschnur erfolgt durch Lösen der durch die Metallhülse bewirkten Klemmverbindung auf das Kuppelglied.From the EP 0 915 195 B1 a clamping device of the type mentioned is known in which the harness cord is guided in the form of a loop through an upper clamping opening of an elastic coupling element, the coupling element being part of the lifting heald. The two ends with the loop of the harness cord are threaded through a metal sleeve which is pushed over the coupling element to maintain a clamp connection. The length of the harness cord is regulated by loosening the clamping connection on the coupling element caused by the metal sleeve.

Die Montage der Harnischschnur beim Stand der Technik, wie oben dargestellt, gestaltet sich aufgrund der Führung des schlaufenförmigen Endes der Harnischschnur etwas aufwendig, was die Montagezeit erhöht.The assembly of the harness cord in the prior art, as shown above, is somewhat complex due to the guidance of the loop-shaped end of the harness cord, which increases the assembly time.

Die der Erfindung zugrunde liegende Aufgabe besteht demzufolge darin, diesbzgl. Abhilfe zu schaffen.The object on which the invention is based is therefore to To remedy the situation.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass die Keilaufnahmeeinrichtung den Klemmkeil in Längsrichtung der Hebelitze verschieblich aufnimmt, wobei die Harnischschnur zwischen Keilaufnahmeeinrichtung und Klemmkeil klemmend erfasst ist, wobei Mittel zur Festlegung des Klemmkeils in der Keilaufnahmeeinrichtung vorgesehen sind.To solve the problem, the invention proposes that the wedge receiving device receives the clamping wedge displaceably in the longitudinal direction of the lifting heald, the harness cord being clamped between the wedge receiving device and the clamping wedge, means for fixing the clamping wedge in the wedge receiving device being provided.

Hieraus wird deutlich, dass zwischen dem Klemmkeil einerseits und der Keilaufnahmeeinrichtung andererseits in Abhängigkeit von der Stellung des Klemmkeils in der Keilaufnahmeeinrichtung ein Abstand zwischen dem Klemmkeil einerseits und der Keilaufnahmeeinrichtung andererseits gebildet wird, in dem die Harnischschnur verläuft. Durch Verschieben des Klemmkeils relativ zur Keilaufnahmeeinrichtung kann nun die Harnischschnur klemmend zwischen Klemmkeil einerseits und Keilaufnahmeeinrichtung andererseits erfasst werden. Um zu gewährleisten, dass die Klemmverbindung aufrechterhalten wird, sind Mittel vorgesehen, die den Klemmkeil in der Keilaufnahmeeinrichtung in der Klemmstellung fixieren.From this it becomes clear that between the clamping wedge on the one hand and the wedge receiving device on the other hand, depending on the position of the clamping wedge in the wedge receiving device, a distance is formed between the clamping wedge on the one hand and the wedge receiving device on the other hand, in which the harness cord runs. By moving the clamping wedge relative to the wedge receiving device, the harness cord can now be grasped in a clamping manner between the clamping wedge on the one hand and the wedge receiving device on the other hand. In order to ensure that the clamping connection is maintained, means are provided which fix the clamping wedge in the wedge receiving device in the clamping position.

Vorteilhafte Merkmale und Ausgestaltungen zu der Erfindung ergeben sich aus den Unteransprüchen.Advantageous features and embodiments of the invention emerge from the subclaims.

So ist insbesondere vorgesehen, dass der Klemmkeil eine erste Anlagefläche für die Harnischschnur aufweist, die vorteilhaft verzahnt ist. Die erste Anlagefläche für die Harnischschnur verläuft vorteilhaft in einem Winkel α, beispielsweise zwischen 10° und 20° zur Senkrechten, dass heißt, zur Längsachse der Dreherbindungsvorrichtung. Korrespondierend hierzu weist die Keilaufnahmeeinrichtung in etwa parallel zu der ersten Anlagefläche verlaufend eine zweite Anlagefläche auf, sodass bei Verschieben des Klemmkeils unter Verjüngung des Abstands zwischen der ersten und der zweiten Anlagefläche die Harnischschnur klemmend erfasst wird.In particular, it is provided that the clamping wedge has a first contact surface for the harness cord, which is advantageously toothed. The first contact surface for the harness cord advantageously extends at an angle α, for example between 10 ° and 20 ° to the vertical, that is to say to the longitudinal axis of the leno tying device. Corresponding to this, the wedge receiving device has a second contact surface running approximately parallel to the first contact surface, so that when the clamping wedge is displaced, the distance between the two is tapered the harness cord is grasped in a clamping manner on the first and second contact surfaces.

Bereits an anderer Stelle wurde dargelegt, dass Mittel zur Festlegung des Klemmkeils in der Keilaufnahmeeinrichtung vorgesehen sind. Vorteilhaft umfassen die Mittel eine Feder, die auf den Klemmkeil wirkt. Das heißt, dass der Klemmkeil unter der Last einer Feder steht. Somit wirkt die Kraft der Feder in Längsrichtung der Hebelitze auf den Klemmkeil derart, dass die Klemmverbindung für die Harnischschnur aufrechterhalten bleibt. Das heißt aber auch, dass die Kraft der Feder maßgeblich für die Klemmkraft ist. Hierbei kann nach einem weiteren Merkmal der Erfindung die Feder als Druckfeder ausgebildet sein, und besonders vorteilhaft als Spiralfeder. Tatsächlich tritt aber auch in Bezug auf die Harnischschnur Selbsthemmung ein; dies dann, wenn die Harnischschnur an der ersten und der zweiten Anlagefläche einliegt und die Harnischschnur auf Zug in Richtung nach oben beansprucht wird.It has already been explained elsewhere that means are provided for fixing the clamping wedge in the wedge receiving device. The means advantageously comprise a spring which acts on the clamping wedge. This means that the clamping wedge is under the load of a spring. The force of the spring thus acts on the clamping wedge in the longitudinal direction of the lifting heald in such a way that the clamping connection for the harness cord is maintained. But this also means that the force of the spring is decisive for the clamping force. According to a further feature of the invention, the spring can be designed as a compression spring, and particularly advantageously as a spiral spring. In fact, self-locking also occurs with regard to the harness cord; this when the harness cord rests on the first and second contact surfaces and the harness cord is subjected to tensile stress in the upward direction.

Denkbar ist zur Festlegung des Klemmkeils in der Keilaufnahmeeinrichtung allerdings auch, den Klemmkeil mit einer Reihe von übereinander angeordneten Bohrungen zu versehen, um nach Spannen des Klemmkeiles in der Keilaufnahmeeinrichtung zur Fixierung der Harnischschnur durch die letzte sichtbare Bohrung einen Stift zu führen, um so eine mechanische Fixierung der Stellung des Klemmkeiles relativ zur Keilaufnahmeeinrichtung zu bewirken.To fix the clamping wedge in the wedge receiving device, however, it is also conceivable to provide the clamping wedge with a series of holes arranged one above the other in order to guide a pin through the last visible hole after tensioning the clamping wedge in the wedge receiving device to fix the harness cord, in order to create a mechanical one To effect fixing of the position of the clamping wedge relative to the wedge receiving device.

Die Keilaufnahmeeinrichtung umfasst ein Bein, dass der Verbindung mit der Hebelitze dient. Das Bein weist eine Führung für die Feder auf, wobei die Führung vorteilhaft als Führungsbohrung ausgebildet ist. DieThe wedge receiving device comprises a leg that is used to connect to the lifting heald. The leg has a guide for the spring, the guide advantageously being designed as a guide bore. The

Führungsbohrung weist vorteilhaft ein längsverlaufendes Fenster auf, durch das die Feder zugänglich ist, um die Feder beim Einsetzen des Klemmkeils zusammendrücken zu können. Das Bein kann ein gesondertes Bauteil sein, das mit der Hebelitze, z. B. durch Kleben, verbunden ist; es kann aber auch zusammen mit der Hebelitze einteilig hergestellt sein.Guide bore advantageously has a longitudinal window through which the spring is accessible in order to be able to compress the spring when the clamping wedge is inserted. The leg can be a separate component that is connected to the lifting heald, e.g. B. by gluing, connected; but it can also be made in one piece together with the lifting heald.

Gegenstand der Erfindung ist auch eine Jacquard-Maschine mit einer Vorrichtung gemäß einem oder mehrerer der Ansprüche 1 bis 12.The invention also relates to a jacquard machine with a device according to one or more of claims 1 to 12.

Anhand der Zeichnungen wird die Erfindung beispielhaft näher erläutert.

Die Dreherbindungsvorrichtung 1 umfasst die beiden Hebelitzen 3 und 5, die jeweils wechselweise die Halblitze 7 zur Bildung einer Dreherbindung mitnehmen. Das Prinzip ist bekannt, wobei diesbzgl. beispielsweise auf die EP 2 236 655 B1 verwiesen wird. Gegenstand der Erfindung ist nun, die Verbindung der Harnischschnur 10 mit der jeweiligen Hebelitze 3, 5. Hierzu ist die Klemmvorrichtung 20 vorgesehen, wobei die Klemmvorrichtung 20 die Keilaufnahmeeinrichtung 22 und den durch die Keilaufnahmeeinrichtung 22 aufgenommenen Klemmkeil 24 umfasst.The leno binding device 1 comprises the two lifting healds 3 and 5, which alternately take along the half heald 7 to form a leno binding. The principle is known. for example on the EP 2 236 655 B1 is referred. The subject of the invention is the connection of the harness cord 10 to the respective lifting heald 3, 5. The clamping device 20 is provided for this purpose, the clamping device 20 comprising the wedge receiving device 22 and the clamping wedge 24 received by the wedge receiving device 22.

Fig. 2 zeigt die Klemmvorrichtung in vergrößerter Darstellung; hierbei ist bereits erkennbar, dass der Klemmkeil eine erste Anlagefläche 28 aufweist, die eine Verzahnung 29 zeigt. Erkennbar ist auch, dass die Harnischschnur 10 an der ersten Anlagefläche 28 anliegt. Aus den Figuren 3 bis 7 ergibt sich nunmehr die Ausbildung der Klemmvorrichtung 20 im Detail. So ist insbesondere aus Fig. 4 erkennbar, dass korrespondierend zu der ersten Anlagefläche 28 des Klemmkeils 24, die vorteilhaft in einem Winkel von etwa 10° bis 20° zur Senkrechten verläuft, die Keilaufnahmeeinrichtung 22 eine korrespondierende zweite Anlagefläche 30 aufweist, wobei zwischen der ersten Anlagefläche 28 und der zweiten Anlagefläche 30 ein Abstand besteht, in welchem die Harnischschnur 10 verläuft. Erkennbar ist ebenfalls das Bein 26 als Teil der Klemmvorrichtung 20. Das Bein 26 weist eine Führungsbohrung 34 zur Aufnahme der Druckfeder 32 auf. Die Druckfeder 32 in dem Bein 26 wirkt in der figürlichen Darstellung von unten auf den Klemmkeil, sodass der Klemmkeil 24 unter der Last der Feder 32 das Bestreben hat, den Abstand zwischen der ersten und der zweiten Anlagefläche 28, 30 zu minimieren, um so die Klemmverbindung für die Harnischschnur 10 bereitzustellen. Die Führungsbohrung 34 weist ein längliches Fenster 35 auf, durch das die Feder 32 für einen spitzen Gegenstand zugänglich ist. Dies, um bei der Montage die Feder 32 zusammendrücken zu können. Fig. 2 shows the clamping device in an enlarged view; It can already be seen here that the clamping wedge has a first contact surface 28 which shows a toothing 29. It can also be seen that the harness cord 10 rests on the first contact surface 28. From the Figures 3 to 7 The formation of the clamping device 20 now results in detail. So in particular is off Fig. 4 It can be seen that corresponding to the first contact surface 28 of the clamping wedge 24, which advantageously runs at an angle of approximately 10 ° to 20 ° to the vertical, the wedge receiving device 22 has a corresponding second contact surface 30, with between the first contact surface 28 and the second contact surface 30 there is a distance in which the harness cord 10 runs. The leg 26 can also be seen as part of the clamping device 20. The leg 26 has a guide bore 34 for receiving the compression spring 32. The compression spring 32 in the leg 26 acts in the figurative representation from below on the clamping wedge, so that the clamping wedge 24, under the load of the spring 32, tends to minimize the distance between the first and the second contact surface 28, 30 in order to To provide a clamping connection for the harness cord 10. The guide bore 34 has an elongated window 35 through which the spring 32 for a pointed Subject is accessible. This in order to be able to compress the spring 32 during assembly.

Fig. 6 zeigt im Einzelnen die Stellung des Klemmkeiles 24 in der Keilaufnahmeeinrichtung 22 zum Einfädeln der Harnischschnur entsprechend dem Pfeil 42. Das heißt, dass in diesem Fall die Feder 32 in der Führungsbohrung 34 des Beines 26 komprimiert ist. Fig. 7 zeigt eine Ansicht von oben auf die Klemmvorrichtung 20 gemäß Fig. 6; hierbei ist erkennbar, dass der Klemmkeil 24 durch eine Führungseinrichtung 36 in der Keilaufnahmeeinrichtung 22 geführt ist. Die Führungseinrichtung 36 umfasst im Einzelnen eine zu beiden Seiten des Klemmkeils angeordnete leistenförmige Nase 38, die in eine entsprechende Nut 40 in der Keilaufnahmeeinrichtung 22 läuft. Erkennbar ist ebenfalls die Führungsbohrung 34 für die Feder 32 in dem Bein 26. Ebenfalls erkennbar ist die verzahnte erste Anlagefläche 28 des Klemmkeils 24. Fig. 6 shows in detail the position of the clamping wedge 24 in the wedge receiving device 22 for threading the harness cord according to the arrow 42. This means that in this case the spring 32 is compressed in the guide bore 34 of the leg 26. Fig. 7 FIG. 11 shows a view from above of the clamping device 20 according to FIG Fig. 6 ; It can be seen here that the clamping wedge 24 is guided by a guide device 36 in the wedge receiving device 22. The guide device 36 specifically comprises a strip-shaped nose 38 which is arranged on both sides of the clamping wedge and which runs into a corresponding groove 40 in the wedge receiving device 22. The guide bore 34 for the spring 32 in the leg 26 can also be seen. The toothed first contact surface 28 of the clamping wedge 24 can also be seen.

Fig. 8 zeigt in einer explosionsartigen Darstellung die Klemmvorrichtung 20; hierbei ist insbesondere noch einmal das Bein der Klemmvorrichtung 20 erkennbar, das am unteren Ende mit der jeweiligen Hebelitze 3, 5, beispielsweise durch Kleben, verbunden ist. Fig. 8 shows the clamping device 20 in an exploded view; in particular, the leg of the clamping device 20 can be seen again, which is connected at the lower end to the respective lifting heald 3, 5, for example by gluing.

Die Montage der Klemmvorrichtung 20 ist nun derart, dass der Klemmkeil 24 von unten in die Keilaufnahmeeinrichtung 22 eingeschoben wird, wobei zuvor die Feder in die Führungsbohrung 34 eingeführt ist. Die Führungsbohrung 34 weist das Fenster 35 auf, wobei durch das Fenster 35, beispielsweise mittels eines Schraubendrehers, die Feder während des Einführens des Klemmkeiles zusammengedrückt werden kann. Zum Einfädeln der Harnischschnur 10 wird nun der Klemmkeil 24 in der Keilaufnahmeeinrichtung 22 soweit nach unten geschoben, bis etwa die Oberseite des Klemmkeils 24 etwa mit der Oberseite der Keilaufnahmeeinrichtung 22 abschließt. Alsdann wird die Harnischschnur entsprechend dem Pfeil 42 gemäß Fig. 6 von oben eingefädelt. Wird der Klemmkeil von der von oben aufgebrachten Kraft entlastet, schnellt er aufgrund der Kraft der Feder 32 nach oben, und bewirkt insofern die Klemmverbindung für die Harnischschnur 10.The assembly of the clamping device 20 is now such that the clamping wedge 24 is pushed from below into the wedge receiving device 22, the spring having previously been inserted into the guide bore 34. The guide bore 34 has the window 35, the spring being able to be compressed through the window 35, for example by means of a screwdriver, during the introduction of the clamping wedge. To thread the harness cord 10, the clamping wedge 24 in the wedge receiving device 22 is now pushed down until approximately the top of the clamping wedge 24 is approximately flush with the top of the wedge receiving device 22. Then the harness cord according to arrow 42 according to Fig. 6 threaded from above. If the clamping wedge is relieved of the force applied from above, it snaps upwards due to the force of the spring 32, and in this respect causes the clamping connection for the harness cord 10.
