The gripper has two clamping jaws (19,21) with the gripping surface for clamping a pile yarn (9). A hinge (32) connects both the clamping jaws with one another in a rotatable manner and determines a rotation axis (33). One clamping jaw has an axial bearing surface (36) for forming the hinge, where a spacer has an attachment surface (39). A holding element (46) rests on the attachment surface and comprises a plate-shaped or disk-shaped head (48). An axial bearing surface (49) is held by the spacer at a distance from the axial bearing surface of the clamping jaw.

Description

Die Erfindung betrifft einen Greifer für eine Axminster-Webmaschine.The invention relates to a gripper for an Axminster loom.

Zur Herstellung von Teppichen und anderen Flortextilien ist das Axminster-Weben bekannt. Die prinzipielle Funktion solcher Webmaschinen ist der Literaturstelle "Carpet Manufacture" (Teppichherstellung Geoffrey H. Crawshaw, WRONZ Developments, Private Bag 4749, Christchurch New Zealand) zu entnehmen. Die Webmaschine arbeitet mit drei Kettfadengruppen, denen entsprechende Webschäfte zugeordnet sind. Mittels auf einer Barre sitzender Greifer werden vorgeschnittene Florfäden zwischen die Kettfäden gereicht und dort mittels Schussfäden verankert.For the production of carpets and other pile textiles the Axminster weaving is known. The principle function of such weaving machines can be found in the reference "Carpet Manufacture" (carpet production Geoffrey H. Crawshaw, WRONZ Developments, Private Bag 4749, Christchurch New Zealand). The weaving machine works with three warp thread groups, which are assigned corresponding healds. By means of a gripper sitting on a bar, pre-cut pile threads are made passed between the warp threads and anchored there by means of weft threads.

Axminster Webmaschinen stellen hohe Anforderungen an die Präzision des Betriebs der Greifer. Die auf einer Barre sitzenden gleichzeitig arbeitenden Greifer müssen die Fäden präzise ergreifen und zwischen die Kettfäden reichen können. Die Greifer müssen dabei relativ schmal ausgebildet werden, damit sie zwischen die Kettfäden passen. Die Greifer werden dabei üblicherweise jeweils von zwei sehr schmalen Klemmbacken gebildet, die durch einen Niet zusammengehalten werden. Der Niet bildet ein Gelenk, das ein Öffnen und Schließen der von den Klemmbacken gebildeten Zange gestattet.Axminster weaving machines place high demands on the precision of the operation of the grippers. The co-operating grippers sitting on a bar must be able to grasp the threads precisely and pass between the warp threads. The grippers must be made relatively narrow so that they fit between the warp threads. The grippers are usually each formed by two very narrow jaws, which are held together by a rivet. The rivet forms a hinge which permits opening and closing of the pliers formed by the jaws.

Ein solcher Greifer ist beispielsweise aus der GB 1 353 153 bekannt. Zur Ausbildung des Niets ist einer der Klemmbacken an einer abgeflachten Stelle mit einem kurzen Rohrfortsatz versehen, der als Hohlniet dient und in eine entsprechende Ausnehmung des anderen Klemmbackens eingebördelt wird.Such a gripper is for example from the GB 1 353 153 known. To form the rivet, one of the jaws is provided at a flattened point with a short tube extension, which serves as a hollow rivet and is crimped into a corresponding recess of the other jaw.

Die Anordnung ist in mehrerlei Hinsicht kritisch, denn der gebördelte Bereich des rohrförmigen Fortsatzes ist zugleich Niet und Lagerung.The arrangement is critical in several respects, because the flanged portion of the tubular extension is at the same time rivet and storage.

Die DE 10 2004 061 166 A1 verbessert die Lagerung in dem der eine mit einer Vertiefung versehene Klemmbacken an der Vertiefung eine ringförmige Rippe erhält, die in eine Ringnut des anderen Klemmbacken greift. Damit werden die Lagerverhältnisse der beiden Klemmbacken aneinander erheblich verbessert. Andererseits stellt diese Lösung hohe Anforderungen an die Fertigungstechnik. Bei der Verbindung der beiden Klemmbacken durch Umformen der einen Kante der zylindrischen Lagerfläche des Rohrfortsatzes muss das gewünschte Spiel zwischen den beiden Klemmbacken definiert eingestellt werden. Die Klemmbacken dürfen nicht zu schwergängig aber auch nicht zu leichtgängig sein.The DE 10 2004 061 166 A1 improves the storage in which receives a recessed jaws on the recess an annular rib which engages in an annular groove of the other jaws. Thus, the storage conditions of the two jaws together are significantly improved. On the other hand, this solution places high demands on the production technology. When connecting the two jaws by forming the one edge of the cylindrical bearing surface of the tube extension, the desired clearance between the two jaws must be set defined. The jaws must not be too stiff but not too smooth.

Aus der US 1,816,938 ist ferner ein Greifer gemäß dem Oberbegriff des Anspruchs 1 bekannt, dessen beide Klemmbacken mit Hilfe eines Halteelements in Form einer flachen Scheibe aneinander gehalten werden. In einer Ausnehmung des ersten Klemmbackens ist ein Abschnitt des zweiten Klemmbackens gelagert und dort zwischen dem ersten Klemmbacken und die Scheibe gehalten. Die Scheibe ist durch Nieten am ersten Klemmbacken befestigt.From the US 1,816,938 Further, a gripper according to the preamble of claim 1 is known, the two jaws are held together by means of a holding element in the form of a flat disc. In a recess of the first jaw, a portion of the second jaw is supported and held there between the first jaw and the disc. The disc is attached by riveting on the first jaw.

Es ist Aufgabe der Erfindung, einen verbesserten Greifer für eine Axminster-Webmaschine anzugeben.It is an object of the invention to provide an improved gripper for an Axminster loom.

Diese Aufgabe wird mit dem Greifer nach Anspruch 1 gelöst:This object is achieved with the gripper according to claim 1:

Der erfindungsgemäße Greifer weist zwei Klemmbacken auf, die durch ein Gelenk miteinander verbunden sind. Den ersten Klemmbacken sind zur Ausbildung des Gelenks zwei Axiallagerflächen zugeordnet, die durch einen Abstandshalter auf Abstand zueinander gehalten sind. Der Abstandshalter kann als separates Bauelement oder als Bestandteil einer der Klemmbacken ausgebildet sein. Vorzugsweise ist zumindest eine der Axiallagerflächen unmittelbar an dem Klemmbacken ausgebildet, während die andere der beiden Axiallagerflächen an einem gesonderten Element ausgebildet ist.The gripper according to the invention has two clamping jaws, which are connected to each other by a hinge. The first jaws are assigned to the formation of the joint, two thrust bearing surfaces, which are held by a spacer at a distance from each other. The spacer may be formed as a separate component or as part of one of the jaws. Preferably, at least one of the thrust bearing surfaces is formed directly on the jaw, while the other of the two thrust bearing surfaces is formed on a separate element.

Durch den Abstandshalter wird das Axialspiel des zweiten Klemmbackens definiert festgelegt. Insbesondere wird dieses Axialspiel nicht von der Verbindungstechnik beeinflusst, mittels derer das Halteelement mit dem ersten Klemmbacken verbunden ist. Beispielsweise können dazu formschlüssige Verbindungen wie z.B. Bördelverbindungen, Nietverbindungen, Schraubverbindungen etc. und/oder Stoffschlüssige Verbindungen wie z.B. Laserschweißverbindungen, Klebeverbindungen und ähnliches dienen.By the spacer is the axial play of the second Jaw defined defines. In particular, this axial play is not influenced by the connection technique, by means of which the holding element is connected to the first clamping jaw. For example, form-fitting connections such as crimp connections, rivet connections, screw connections etc. and / or cohesive connections such as laser welding connections, adhesive connections and the like can serve this purpose.

Der Abstandshalter kann ein ring- oder rohrförmiger Fortsatz des ersten Klemmbackens sein. Dieser weist an seiner Stirnfläche dann eine Auflagefläche auf, an der das Halteelement seine Anlage findet. Das Halteelement erstreckt sich durch eine Öffnung, die von der Auflagefläche umschlossen wird und ist in dieser Öffnung gesichert. Dazu können die oben genannten Verbindungstechniken einzeln oder in Verbindung miteinander dienen.The spacer may be an annular or tubular extension of the first jaw. This then has on its end face on a support surface on which the holding element finds its investment. The holding element extends through an opening which is enclosed by the support surface and is secured in this opening. For this purpose, the above-mentioned joining techniques may be used individually or in conjunction with each other.

Das Halteelement wird von einem vorzugsweise scheibenförmigen Kopf gebildet, der eine Ringfläche aufweist, die auf der Auflagefläche aufliegt und diese in Radialrichtung überragt. Der überragende Teil bildet dann die Axiallagerfläche für den zweiten Klemmbacken. Der Kopf des Halteelements liegt dabei vorzugsweise in einer Ausnehmung des zweiten Klemmbackens, so dass der Greifer im Wesentlichen ebene Seitenflächen ohne Erhebungen aufweist. Der Greifer ist dadurch im Wesentlichen glatt. Das Halteelement schließt mit zumindest einem, vorzugsweise beiden Klemmbacken, insbesondere mit deren Flachseiten, bündig ab. Der Greifer kann dadurch leicht zwischen die Kettfäden greifen, ohne an den Kettfäden hängen zu bleiben und diese zu beschädigen.The holding element is formed by a preferably disc-shaped head, which has an annular surface which rests on the support surface and projects beyond it in the radial direction. The towering part then forms the thrust bearing surface for the second jaw. The head of the retaining element is preferably located in a recess of the second jaw, so that the gripper has substantially flat side surfaces without elevations. The gripper is characterized essentially smooth. The holding element closes flush with at least one, preferably both jaws, in particular with their flat sides. The gripper can thus easily grip between the warp threads, without hanging on the warp threads and damage them.

Der Abstandshalter weist vorzugsweise einen zylindrischen Außenumfang auf, der als Lagerfläche (Radiallagerfläche) für den zweiten Klemmbacken dienen kann. Damit lässt sich eine durchaus ausreichende Lagerung und Präzision erzielen. Es kann jedoch vorteilhaft sein, die Radiallagerung zu unterstützen, indem an einem der Klemmbacken eine Nut oder sonstige Vertiefung angebracht wird, die sich um die Scharnierachse krümmt. Die Nut kann bogenförmig oder ringförmig ausgebildet sein. An dem anderen Klemmbacken können entsprechend ein oder mehrere Vorsprünge vorgesehen sein, die in diese Nut greifen und in dieser gleiten. Der Vorsprung kann als gebogene Rippe oder als geschlossene ringförmige Rippe ausgebildet sein. Die Flanken der bogen- oder ringförmigen Nut und die Flanken der bogen- oder ringförmigen Rippe können eine Radiallagerung bilden.The spacer preferably has a cylindrical outer circumference, which can serve as a bearing surface (radial bearing surface) for the second jaw. This can be a quite sufficient storage and precision. However, it may be advantageous to support the radial bearing by attaching to one of the jaws a groove or other depression that curves around the hinge axis. The groove may be arcuate or annular. On the other jaws can be provided correspondingly one or more projections which engage in this groove and slide in this. The projection may be formed as a curved rib or as a closed annular rib. The flanks of the arcuate or annular groove and the flanks of the arcuate or annular rib can form a radial bearing.

In Fig. 1 ist eine Axminster-Webmaschine 1 stark vereinfacht veranschaulicht. Sie dient zur Herstellung einer Florware. Sie weist mehrere nicht veranschaulichte Kettbäume auf, von denen mehrere Kettfäden 2, 3, 4 herangeführt werden. Mit den Kettfäden 2, 3, 4 werden Fächer gebildet, in die ein oder meist zwei Schussfäden 5 eingetragen werden, wie es Fig. 2 zeigt. Zur Fachbildung dienen Webschäfte 6, 7, 8, die die Kettfäden 2, 3, 4 mittels Litzen führen.In Fig. 1 An Axminster weaving machine 1 is illustrated in a highly simplified manner. It is used to produce a pile fabric. It has a plurality of not illustrated warp beams, of which a plurality of warp threads 2, 3, 4 are introduced. With the warp threads 2, 3, 4 subjects are formed, in which one or usually two weft threads 5 are registered, as it Fig. 2 shows. To shed serve heald shafts 6, 7, 8, which lead the warp threads 2, 3, 4 by means of strands.

Zum Einsetzen vorgeschnittener Florfäden 9 in das Gewebe dient eine Greifereinrichtung 10 mit mehreren Greifern 11. Die Greifereinrichtung 10 mit den Greifern 11 ist zwischen einer Position A, in der sie Florfäden 9 in das Gewebe einsetzt und einer Position B beweglich, in der sie Florfäden von einem Fadenträger 12 abholt. Der Fadenträger 12 kann mehrere Fäden 13, 14 unterschiedlicher Farbe bereithalten und so gesteuert sein, dass jeweils der gewünschte Faden zum Beispiel mit einer Muster abhängig ausgewählten Farbe abgeholt wird. Ein Messerträger 15 weist ein oder mehrere Messer auf, um von dem Florfaden, dessen Ende die Greifereinrichtung hält, ein Stück einer gewünschten Länge abzuschneiden.The gripper device 10 with the grippers 11 is movable between a position A in which it uses pile threads 9 in the fabric and a position B in which they pile yarns of a thread carrier 12 picks up. The thread carrier 12 can hold a plurality of threads 13, 14 of different colors and be controlled so that in each case the desired thread is picked up, for example, with a pattern depending on the selected color. A knife carrier 15 has one or more knives for cutting off a piece of a desired length from the pile yarn, the end of which holds the gripper means.

Die Greifer 11 sind auf einer Barre 16 gehalten, die eine große Zahl weiterer gleich ausgebildeter Greifer trägt. Diese sind in Fig. 1 senkrecht zur Zeichenebene deckungsgleich übereinander angeordnet. Neben der Barre 16 ist eine Steuerwelle 17 zum Öffnen und Schließen der Greifer 11 vorgesehen. Die Barre 16 und die Steuerwelle 17 sind gemeinsam so schwenkbar, dass die Greifer 11 zwischen den Positionen A und B hin und herbewegt werden.The grippers 11 are held on a bar 16, which carries a large number of other identically designed gripper. These are in Fig. 1 arranged congruently one above the other perpendicular to the plane of the drawing. In addition to the bar 16, a control shaft 17 is provided for opening and closing the gripper 11. The bar 16 and the control shaft 17 are pivotable together so that the grippers 11 are reciprocated between the positions A and B.

Zu der Axminster-Webmaschine 1 gehört außerdem noch eine Anschlagbarre mit entsprechenden Lamellen 18, wie sie beispielsweise aus Fig. 2 ersichtlich sind.To the Axminster weaving machine 1 also belongs one more Anschlagbarre with corresponding blades 18, as for example Fig. 2 can be seen.

Der Greifer 11 weist gemäß Fig. 3 zwei Klemmbacken 19, 21 auf. Der mit der Barre 16 zu verbindende Klemmbacken 19 wird häufig als Grundteil bezeichnet. Der an dem Klemmbacken 19 schwenkbar gelagerte Klemmbacken 21 wird häufig als Hebel bezeichnet. Die Klemmbacken 19, 21 sind flache Blechteile mit einer Dicke zwischen einem oder wenigen Millimetern. Sie weisen senkrecht zur Zeichenebene in Fig. 3 eine übereinstimmende Dicke auf, die zwischen den Seitenflächen 43 und 47 festgelegt ist (Figur 5). Ihre Flanken liegen im Wesentlichen in gleichen Ebenen, d.h. die Klemmbacken 19, 20 sind ohne seitlichen Versatz zueinander angeordnet. Der Klemmbacken 19 ist an einem Ende 22 mit einem Befestigungsprofil 23 in Form eines T-Ausschnitts versehen. An seinem anderen Ende 24 läuft er bei gleichbleibender Dicke keilförmig aus. Zum Ergreifen des Fadens kann an dem Ende 24 eine Greiferfläche 25 angebracht sein.The gripper 11 has according to Fig. 3 two jaws 19, 21 on. The to be connected to the Barre 16 jaws 19 is often referred to as a base. The pivotally mounted on the jaws 19 jaws 21 is often referred to as a lever. The jaws 19, 21 are flat sheet metal parts with a thickness between one or a few millimeters. They point perpendicular to the drawing plane in Fig. 3 a matching thickness defined between the side surfaces 43 and 47 ( FIG. 5 ). Their flanks are substantially in the same planes, ie the jaws 19, 20 are arranged without lateral offset to each other. The clamping jaw 19 is provided at one end 22 with a fastening profile 23 in the form of a T-section. At its other end 24, it runs in a wedge shape with the same thickness. To grasp the thread, a gripper surface 25 may be attached to the end 24.

Der Klemmbacken 21 weist für die Steuerwelle 17 an einem Ende 27 ein Kupplungsprofil 26 auf. Das andere Ende 28 des Klemmbackens 21 ist wiederum keilförmig ausgebildet und mit einer Greiferfläche 29 versehen. Die Enden 24, 28 der Klemmbacken 19, 21 bilden einen spitz zulaufenden Schnabel 31. Zur gelenkigen Lagerung der Klemmbacken 19, 21 aneinander dient ein Gelenk 32. Das Gelenk 32 legt eine quer zu den Klemmbacken 19, 21 und somit in Fig. 3 senkrecht zur Zeichenebene stehende Gelenk- bzw. Schwenkachse 33 fest.The jaws 21 has a coupling profile 26 for the control shaft 17 at one end 27. The other end 28 of the jaw 21 is again wedge-shaped and provided with a gripper surface 29. The ends 24, 28 of the jaws 19, 21 form a tapered beak 31. For articulated mounting of the jaws 19, 21 to each other is a hinge 32. The hinge 32 defines a transverse to the jaws 19, 21 and thus in Fig. 3 fixed to the plane of articulation or pivot axis 33 fixed.

Fig. 4 veranschaulicht die beiden Klemmbacken 19, 21 voneinander getrennt. Zu dem Gelenk 32 gehören kreisringförmige abgeflachte Abschnitte 34, 35 an den Klemmbacken 19, 21. Diese Abschnitte weisen ringförmige Planflächen 36, 37 auf, die als Axiallagerflächen dienen. Die ringförmige Planfläche 36 wird innen von einem Rohrfortsatz 38 begrenzt, der an seiner Stirnseite eine ringförmige ebene Auflagefläche 39 aufweist. Dem Rohrfortsatz 38 des Klemmbackens 19 ist eine Öffnung 40 zugeordnet, deren Durchmesser mit dem Durchmesser des Rohrfortsatzes 38 bis auf ein geringes Spiel übereinstimmt. Der Rohrfortsatz 38 kann somit als Radiallager dienen. Zur Unterstützung der Radiallagerwirkung können der Klemmbacken 19 oder 21 mit einer zum Beispiel ringförmigen, zu dem Rohrfortsatz 38 bzw. der Öffnung 40 konzentrischen Ringnut 41 und der entsprechende andere der Klemmbacken 19, 21 mit einer dazu passenden Form, wie beispielsweise einer ringförmigen Rippe 42 versehen sein. Fig. 4 illustrates the two jaws 19, 21 separated from each other. To the joint 32 include annular flattened portions 34, 35 on the jaws 19, 21. These sections have annular planar surfaces 36, 37, which serve as thrust bearing surfaces. The annular planar surface 36 is bounded on the inside by a tubular extension 38, which has an annular planar bearing surface 39 on its end face. The tube extension 38 of the jaw 19 is associated with an opening 40 whose diameter matches the diameter of the tube extension 38 to a small clearance. The tube extension 38 can thus serve as a radial bearing. To assist the radial bearing action, the jaws 19 or 21 may be provided with an annular annular groove 41 concentric with the tube extension 38 and the aperture 40, respectively, and the corresponding other of the jaws 19, 21 with a mating shape such as an annular rib 42 be.

Der weitere Aufbau des Gelenks 32 ergibt sich aus Fig. 5. Wie ersichtlich, ist die Höhe des Rohrfortsatzes 38, die zwischen der Seitenfläche 47 und der Auflagefläche 39 gemessen wird, geringer als der Abstand zwischen den Seitenflächen 43 und 47 des Klemmbackens 19. Die Auflagefläche 39 liegt deshalb gegen die Seitenfläche 43 des Klemmbackens 19 zurückversetzt. Ausgehend von der Seitenfläche 47 überragt die Auflagefläche 39 des Rohrfortsatzes 38 die Planfläche 36 des Abschnitts 34. DieThe further construction of the joint 32 results from Fig. 5 , As can be seen, the height of the tube extension 38, which is measured between the side surface 47 and the support surface 39, is less than the distance between the side surfaces 43 and 47 of the jaw 19. The support surface 39 is therefore set back against the side surface 43 of the jaw 19. Starting from the side surface 47, the support surface 39 of the tube extension 38 projects beyond the plane surface 36 of the section 34

Der Klemmbacken 21 weist an seinem Abschnitt 35 eine außenliegende, beispielsweise kreisringförmige Tasche 44 auf, deren Boden 65 geringfügig unterhalb der Auflagefläche 39 oder auf gleicher Höhe mit derselben liegt. Mit anderen Worten, die Dicke des Abschnitts 35 ist im Bereich der Tasche 44 ungefähr gleich groß wie die Höhe des Rohrfortsatzes 38 oder ganz geringfügig geringer als diese.The jaw 21 has at its portion 35 an outer, for example, annular bag 44, the bottom 65 is slightly below the support surface 39 or at the same level with the same. In other words, the thickness of the portion 35 in the region of the pocket 44 is approximately equal to the height of the tube extension 38 or slightly less than this.

Die Öffnung 40 wird im vorliegenden Ausführungsbeispiel von dem rohrförmigen Schaft 45 eines Hohlniets 46 durchsetzt, dessen vorzugsweise scheibenförmiger flacher Kopf 48 an der der Auflagefläche 39 zugewandten Seite eine ebene Ringfläche aufweist. Diese liegt auf der Auflagefläche 39 und dient soweit selbst als Auflagefläche. Sie steht außerdem radial über die Auflagefläche 39 über und bildet insoweit eine Axiallagerfläche 49 für den Klemmbacken 21. Die vorzugsweise ebene Außenfläche 50 des Kopfes 48 schließt eben mit der Seitenfläche 43 ab.In the present exemplary embodiment, the opening 40 is penetrated by the tubular shaft 45 of a hollow rivet 46, whose preferably disk-shaped flat head 48 has a flat annular surface on the side facing the bearing surface 39. This lies on the support surface 39 and serves as far as itself as a support surface. It also protrudes radially beyond the bearing surface 39 and thus forms an axial bearing surface 49 for the clamping jaw 21. The preferably flat outer surface 50 of the head 48 just ends with the lateral surface 43.

Der Schaft 45 des Hohlniets 46 ist an seinem der Außenfläche 50 gegenüberliegenden Rand in eine entsprechende Ausnehmung des Klemmbackens 19 gebördelt. Eine solche Ausnehmung kann beispielsweise durch eine Kegelfläche 51 gebildet werden, mit der sich die Öffnung 40 nach außen hin erweitert. Anstelle der Kegelfläche 51 können auch andere Flächenformen, wie beispielsweise Stufen oder dergleichen vorgesehen werden.The shank 45 of the hollow rivet 46 is crimped at its edge opposite the outer surface 50 into a corresponding recess of the clamping jaw 19. Such a recess can be formed for example by a conical surface 51, with which the opening 40 widens outwards. Instead of the conical surface 51, other surface shapes, such as steps or the like may be provided.

Wie ersichtlich bildet der Rohrfortsatz 38 einen Abstandshalter, der den Kopf 48 des Hohlniets 46 und somit dessen Axiallagerfläche 49 in definiertem Abstand zu der Axiallagerfläche 36 hält. Der Abstand wird dabei parallel zu der Gelenkachse 33 gemessen. Dieser Abstand ist geringfügig größer als die Dicke des Abschnitts 35 in gleicher Messrichtung und an gleicher Stelle. Der ringförmige Zwischenraum zwischen der Axiallagerfläche 36 und der zu ihr parallel orientierten Axiallagerfläche 49 bildet eine Lagertasche für den Klemmbacken 21.As can be seen, the tube extension 38 forms a spacer, which holds the head 48 of the hollow rivet 46 and thus its thrust bearing surface 49 at a defined distance from the thrust bearing surface 36. The distance is measured parallel to the hinge axis 33. This distance is slightly greater than the thickness of the portion 35 in the same direction and at the same location. The annular space between the thrust bearing surface 36 and the axial bearing surface 49 oriented parallel to it forms a bearing pocket for the clamping jaw 21.

Der Abstandshalter in Gestalt des Rohrfortsatzes 38 ist hier einstückiger Bestandteil des Klemmbackens 19. Er ermöglicht in Verbindung mit dem Hohlniet46 eine effiziente einfache und prozesssichere Herstellung von Greifern 11 in hoher Qualität. Die Klemmbacken 19, 21 können gegeneinander leicht verschwenkt werden. Die Anordnung der Axiallagerflächen 36, 49 sichern dabei das gewünschte geringe Spiel. Die Radiallagerung wird von dem Rohrfortsatz 38 sowie gegebenenfalls ergänzend oder alternativ von der Ringnut 41 und der Rippe 42 übernommen.The spacer in the form of the tubular extension 38 is here an integral part of the jaw 19. It allows in conjunction with the Hohlniet46 efficient simple and reliable production of grippers 11 in high quality. The jaws 19, 21 can be easily pivoted against each other. The arrangement of the thrust bearing surfaces 36, 49 ensure the desired low clearance. The radial bearing is taken over by the tube extension 38 and optionally in addition or alternatively by the annular groove 41 and the rib 42.

Die Erfindung kann auf vielfältige andere Weise verwirklicht werden. Ein Beispiel zeigt Fig. 6, wobei für gleiche bereits eingeführte Teile ohne erneute Erläuterung die gleichen Bezugszeichen genutzt werden. Auf die vorige Beschreibung wird verwiesen.The invention can be implemented in many other ways. An example shows Fig. 6 , wherein the same reference numerals are used for the same parts already introduced without further explanation. Reference is made to the preceding description.

Als Halteelement ist hier anstelle des Hohlniets 46 eine spezielle Schraube 52 vorgesehen, deren Gewinde tragender Schaft 53 in die mit Gewinde versehene Öffnung 40 eingeschraubt ist. Zur Verdrehsicherung kann die Schraube 52 zusätzlich mit dem Klemmbacken 19 verklebt oder an einer Stelle 54 durch plastische Verformung, einen Schweißpunkt oder dergleichen drehfest gesichert sein.As a holding element here a special screw 52 is provided instead of the hollow rivet 46, the threaded bearing shaft 53 is screwed into the threaded opening 40. To prevent rotation, the screw 52 can additionally glued to the jaws 19 or be secured against rotation at a point 54 by plastic deformation, a weld or the like.

Bei dem erfindungsgemäßen Greifer 11 ist ein Hohlniet 46 vorgesehen, der zusammen mit einem Klemmbacken 19 eine Führungstasche für den anderen Klemmbacken 21 bildet. Die Führungstasche ist zwischen zwei Axiallagerflächen 36, 49 festgelegt. Ein Abstandshalter legt dabei den Abstand zwischen den beiden Axiallagerflächen 36, 49 fest. Er weist dazu eine Anlagefläche 39 auf. Dieser liegt vorzugsweise eine konische Fläche 51 gegenüber. Nach dem Zusammenfügen der beiden Klemmbacken 19, 21 und dem Einsetzen des Hohlniets 46 wird dessen Schaft vorzugsweise so umgeformt, dass dieser an der konischen Fläche 51 anliegt.In the gripper 11 according to the invention, a hollow rivet 46 is provided, which forms a guide pocket for the other clamping jaw 21 together with a clamping jaw 19. The guide pocket is defined between two thrust bearing surfaces 36, 49. A spacer defines the distance between the two thrust bearing surfaces 36, 49. He has for this purpose a contact surface 39. This is preferably a conical surface 51 opposite. After joining the two clamping jaws 19, 21 and the insertion of the tubular rivet 46, its shaft is preferably deformed such that it rests against the conical surface 51.

Bei dieser Anordnung ergibt sich das zur leichtgängigen Bewegung des Greifers 11 erforderliche Spiel aus dem Unterschied zwischen dem Abstand der Auflagefläche 39 des Abstandshalters 38 und der Axialfläche 36 des ersten Klemmbackens und der Höhe des Abschnitts 35 des zweiten Klemmbackens, der in der Führungstasche gelagert ist. Es besteht somit keine Gefahr, dass eine zu starke Umformung des Hohlniets zur Greiferschwergängigkeit führen würde.In this arrangement, this results in the smooth movement of the gripper 11 required clearance from the difference between the distance of the support surface 39 of the spacer 38 and the axial surface 36 of the first jaw and the height of the portion 35 of the second jaw, which is mounted in the guide pocket. There is thus no danger that excessive deformation of the tubular rivet would lead to hook binding.
