- the present invention relates to a clamping device for a flat thread layer with a clamping rail running transversely to the threads of the thread layer.
- Such clamping devices are used for example in warp threading machines and in warp knitting machines for clamping the warp threads. They usually consist of a clamping rail extending over the entire width of the chain and of a rod-shaped clamping comb held in or on the clamping rail, which is pressed into the clamping rail from above and then locked with it. When disassembling after the knotting operation, the clamping rail or comb must be pulled out to the side after loosening the clamping.
- this clamping device is to be used when changing the warp on the weaving machine, then the lateral removal of the clamping comb and / or the clamping rail is very cumbersome for reasons of space alone.
- the clamping rail would also have to be provided in a suitable manner at the clamping point, for which purpose either a lateral insertion before clamping or a permanent arrangement on the weaving machine would be required.
- the former has the disadvantages already mentioned with the clamping comb and the permanent arrangement on the weaving machine would lead to intolerable contamination and dusting of the clamping rail.
- the constant arrangement of the clamping rail on the weaving machine would not incur significant additional costs.
- a clamping device for a flat thread layer is known with a clamping rail running transversely to the threads of the thread layer.
- the clamping rail runs transversely to the threads of the thread layer on one side of the thread layer.
- a cylindrical clamping rod on the other side of the thread layer is pressed against the thread layer and the clamping rail so that the thread layer partially surrounds the clamping rod and is clamped between clamping jaws in the clamping rail and the clamping rod. It is disadvantageous that here too the thread layer has to be inserted between the clamping rail and the clamping rod, or that the clamping rod has to be extended laterally.
- the invention is now to provide a clamping device of the type mentioned, the handling of which is considerably simpler and also more automation-friendly than in the known devices mentioned.
- the clamping member consists of a plurality of clamping elements arranged next to one another, one between an immersion position and a clamping position in or for the Thread layer pivotally adjustable bow or wing-like clamping part.
- the invention thus proposes a one-sided clamping device, so to speak, that is one in which only one side of the thread layer has to be accessible.
- This one-sided clamping device contains, on the one hand, a fixed clamping rail and, on the other hand, clamping elements mounted on it, which are adjustable between two pivot positions.
- the clamping elements can dip into the thread layer from one side. If they are pivoted into the clamping position after passing through the thread layer, then they grip around the thread layer from the other side and, together with the clamping rail, form a clamping gap which is closed when the clamping elements move back to the clamping rail.
- the invention further relates to the use of said clamping device for clamping a warp thread layer.
- FIG. 1 and 2 show a front and a side view of a clamping device according to the invention, which according to the illustration is formed by a clamping rail 1 and by a clamping element Kl to Kn arranged next to one another Clamping element exists.
- the clamping device is used to clamp flat thread layers FS, in particular warp threads and the like.
- the individual threads forming the thread layer FS run perpendicular to the drawing plane in FIG. 1 and horizontally, that is to say transversely across the drawing sheet, in FIG. 2, and they are generally arranged closely next to one another.
- the clamping device according to the invention is a "one-sided", in which the material to be clamped, that is to say the thread layer FS, only needs to be accessible on one side.
- This page is based on FIGS. 1 and 2 the upper side of the thread layer FS; However, depending on the spatial conditions, it can also be the lower side or, in the case of a vertical layer of thread, the left or the right or the rear or the front side.
- the clamping device is positioned on this one side of the thread layer FS, as a result of which the position of the clamping rail 1 is fixed on this one side. Now the clamping elements movable relative to the clamping rail 1 have to be brought to the other side of the thread layer FS to form a clamping gap and finally the clamping gap has to be closed.
- the clamping elements Kl to Kn essentially consist of a bolt 2 which is mounted on the clamping rail 1 in a stroke-displaceable manner and which protrudes from the clamping rail 1 at one end and a wing-like one at this end Clamping part 3 carries.
- This is formed by a relatively thin lamella, tapered towards its free end, both in length and in thickness, which has approximately the shape of an isosceles triangle carried by the bolt 2 at its base. The length of this base is greater than the distance between adjacent bolts 2.
- the clamping parts 3 are aligned such that they run parallel to the threads forming the thread layer FS; they are thus rotated by 90 ° with respect to the position shown in FIGS. 1 and 2. In this position, the clamping parts 3 can easily penetrate the thread layer FS. They are then pivoted back by 90 ° and assume the position shown in the figures, in which they form a coherent clamping member and, together with the clamping rail 1, limit a clamping gap that extends over the width of the thread layer FS.
- the individual bolts 2 are firmly connected in the area of their central part to a support ring or a support slat 4, with which they are supported on a holding member 5 carried by the clamping rail 1.
- the cross-section of the clamping rail 1 has a corresponding shape, for example a C-shaped profile with a bottom 6, a top wall 7 and a rear wall 8. Between the support rings 4 and the top wall 7 act compression springs 9 which press the support ring 4 against the holding member 5 and thus the clamping elements Kl to Kn down.
- FIG. 3 which shows a detailed view in the direction of arrow III of FIG. 1, the bolts 2 and the clamping part 3 are rotated or pivoted by a rod-like slide 10 that extends over the length of the clamping rail 1 , which is articulated with the adjustment arms 11 attached to the individual bolts 2.
- the adjustment path of the slide 10 is limited by stop elements 12 arranged in the clamping rail 1 in such a way that the clamping parts 3 are pivoted parallel and perpendicular to the threads between the two positions.
- the clamping position of the clamping elements Kl to Kn and the adjustment arms 11 is full and the immersion position is shown in dashed lines.
- the clamping parts 3 Since, as already mentioned, the length of the clamping parts 3 at their base is greater than the pitch of the bolts 2, the clamping parts 3 overlap one another by a few millimeters in their clamping position. So that the clamping member formed by the clamping parts 3 of the individual elements Kl to Kn has the smoothest possible surface without laterally protruding edges or corners, the clamping parts are correspondingly graduated in their overlapping area.
- the gradations labeled A are particularly evident from FIG. 3.
- the holding member 5 is formed by two parallel pairs of racks arranged on both sides along the bolts 2 and each containing a first and a second rack 13 or 14.
- the first racks 13, which serve as a support for the support rings 4 and thus for the clamping elements Kl or Kn, are flat on their support edge for the support rings 4 and have teeth on their lower edge.
- they are arranged in the clamping rail 1 so that they can only perform a vertical movement.
- the second racks 14 also have a straight edge and a toothed edge.
- the straight edge serves as a contact surface on the bottom 6 of the clamping rail 1, and the toothing on the other edge is in engagement with the toothing of the first toothed racks 13.
- the second toothed racks 14 are arranged in the clamping rail 1 such that they can only carry out a horizontal adjustment movement in the longitudinal direction of the clamping rail 1. This adjustment is carried out by suitable means, for example by a screw 15 acting between the clamping rail 1 and the second toothed racks 14 (FIG. 1) or by an eccentric, a toggle lever, by hydraulic means or by compressed air.
- the clamping rail 1 is provided on its supporting surface for the thread layer FS which forms the clamping gap with an elastic support 16 made of a suitable material, for example rubber.
- an elastic support 16 made of a suitable material, for example rubber.
- a thread deflection can take place at the clamping point, for which purpose the clamping rail 1 can have a groove 17 along the clamping line (FIG. 2).
- the pad 16 could be omitted.
- a another variant would be to make this groove wider and deeper and to provide it with an elastic insert.
- the described one-sided clamping device can be used especially in the so-called warp preparation, that is when pulling in and tying in warps, and is superior to the conventional two-sided clamping devices, especially when space is limited, such as when used on the weaving machine.
Abstract
Description
Die vorliegende Erfindung betrifft eine Klemmvorrichtung für eine flächige Fadenschicht mit einer quer zu den Fäden der Fadenschicht verlaufenden Klemmschiene.The present invention relates to a clamping device for a flat thread layer with a clamping rail running transversely to the threads of the thread layer.
Derartige Klemmvorrichtungen werden beispielsweise bei Kettfadeneinziehmaschinen und bei Webkettenknüpfmaschinen für das Klemmen der Kettfäden verwendet. Sie bestehen in der Regel aus einer über die gesamte Breite der Kette reichenden Klemmschiene und aus einem in der Klemmschiene oder an dieser gehaltenen, stangenförmigen Klemmkamm, welcher von oben in die Klemmschiene hineingedrückt und dann mit dieser verriegelt wird. Beim Abrüstvorgang nach der Knüpfoperation muss die Klemmschiene oder der Klemmkamm nach dem Lösen der Klemmung seitlich herausgezogen werden.Such clamping devices are used for example in warp threading machines and in warp knitting machines for clamping the warp threads. They usually consist of a clamping rail extending over the entire width of the chain and of a rod-shaped clamping comb held in or on the clamping rail, which is pressed into the clamping rail from above and then locked with it. When disassembling after the knotting operation, the clamping rail or comb must be pulled out to the side after loosening the clamping.
Wenn diese Klemmvorrichtung beim Kettwechsel an der Webmaschine eingesetzt werden soll, dann gestaltet sich das seitliche Herausfahren des Klemmkamms und /oder der Klemmschiene alleine schon aus Platzgründen sehr umständlich. Ausserdem wäre auch die Klemmschiene in geeigneter Art an der Klemmstelle vorzusehen, wofür entweder ein seitliches Einschieben vor dem Klemmen oder eine ständige Anordnung an der Webmaschine erforderlich wären. Ersteres hat die schon beim Klemmkamm erwähnten Nachteile und die permanente Anordnung an der Webmaschine würde zu einer untolerierbaren Verschmutzung und Verstaubung der Klemmschiene führen. Ausserdem würde die ständige Anordnung der Klemmschiene an der Webmaschine nicht unbeträchtliche zusätzliche Kosten mit sich bringen.If this clamping device is to be used when changing the warp on the weaving machine, then the lateral removal of the clamping comb and / or the clamping rail is very cumbersome for reasons of space alone. In addition, the clamping rail would also have to be provided in a suitable manner at the clamping point, for which purpose either a lateral insertion before clamping or a permanent arrangement on the weaving machine would be required. The former has the disadvantages already mentioned with the clamping comb and the permanent arrangement on the weaving machine would lead to intolerable contamination and dusting of the clamping rail. In addition, the constant arrangement of the clamping rail on the weaving machine would not incur significant additional costs.
Aus der US-A-3,696,477 ist eine Klemmvorrichtung für eine flächige Fadenschicht mit einer quer zu den Fäden der Fadenschicht verlaufenden Klemmschiene bekannt. Dabei verläuft die Klemmschiene auf einer Seite der Fadenschicht quer zu den Fäden der Fadenschicht. Für die Klemmung wird eine zylindrische Klemmstange auf der anderen Seite der Fadenschicht so gegen die Fadenschicht und die Klemmschiene gedrückt, dass die Fadenschicht die Klemmstange teilweise umschliesst und zwischen Klemmbacken in der Klemmschiene und der Klemmstange eingeklemmt wird. Nachteilig ist, dass auch hier die Fadenschicht zwischen der Klemmschiene und der Klemmstange eingeführt werden muss, oder dass die Klemmstange seitlich ausgefahren werden muss.From US-A-3,696,477 a clamping device for a flat thread layer is known with a clamping rail running transversely to the threads of the thread layer. The clamping rail runs transversely to the threads of the thread layer on one side of the thread layer. For the clamping, a cylindrical clamping rod on the other side of the thread layer is pressed against the thread layer and the clamping rail so that the thread layer partially surrounds the clamping rod and is clamped between clamping jaws in the clamping rail and the clamping rod. It is disadvantageous that here too the thread layer has to be inserted between the clamping rail and the clamping rod, or that the clamping rod has to be extended laterally.
Wenn man nun gedanklich einen Schritt weitergeht und sich vorstellt, den Kettwechsel auf irgendeine Art und Weise zu automatisieren oder wenigstens in Richtung Automation weiterzuentwickeln, dann wird klar, dass eine derartige Entwicklung durch die bekannten Klemmvorrichtungen sehr stark behindert wäre, indem nämlich das seitliche Ein- oder Ausfahren von Klemmschiene beziehungsweise Klemmkamm ausserordentlich automatisierungsfeindlich ist.If you now go a step further and imagine automating the chain change in some way or at least further developing it in the direction of automation, then it becomes clear that such a development is due to the known clamping devices would be severely hampered, namely that the lateral retraction or extension of the clamping rail or clamping comb is extremely hostile to automation.
Durch die Erfindung soll nun eine Klemmvorrichtung der eingangs genannten Art angegeben werden, deren Handhabung wesentlich einfacher und auch automatisierungsfreundlicher ist als bei den erwähnten bekannten Vorrichtungen.The invention is now to provide a clamping device of the type mentioned, the handling of which is considerably simpler and also more automation-friendly than in the known devices mentioned.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Klemmorgan aus einer Mehrzahl von nebeneinander angeordneten Klemmelementen besteht, welche einen zwischen einer Eintauchstellung und einer Klemmstellung in beziehungsweise für die Fadenschicht schwenkverstellbaren bügel- oder flügelartigen Klemmteil aufweisen.This object is achieved according to the invention in that the clamping member consists of a plurality of clamping elements arranged next to one another, one between an immersion position and a clamping position in or for the Thread layer pivotally adjustable bow or wing-like clamping part.
Die Erfindung schlägt also eine sozusagen einseitige Klemmvorrichtung vor, das ist eine solche, bei der nur eine Seite der Fadenschicht zugänglich sein muss. Dies im Unterschied zu den bekannten Klemmvorrichtungen, bei denen Klemmschiene und Klemmkamm in ihrer Ausgangsposition zu beiden Seiten der Fadenschicht angeordnet sind. Diese einseitige Klemmvorrichtung enthält einerseits eine feste Klemmschiene und andererseits an dieser gelagerte Klemmelemente, die zwischen zwei Schwenkstellungen verstellbar sind.The invention thus proposes a one-sided clamping device, so to speak, that is one in which only one side of the thread layer has to be accessible. This differs from the known clamping devices, in which the clamping rail and clamping comb are arranged on both sides of the thread layer in their starting position. This one-sided clamping device contains, on the one hand, a fixed clamping rail and, on the other hand, clamping elements mounted on it, which are adjustable between two pivot positions.
In der sogenannten Eintauchstellung können die Klemmelemente von einer Seite in die Fadenschicht eintauchen. Werden sie nach dem Durchtritt durch die Fadenschicht in die Klemmstellung geschwenkt, dann umgreifen sie die Fadenschicht von der anderen Seite und bilden zusammen mit der Klemmschiene einen Klemmspalt, der bei Rückbewegung der Klemmelemente zur Klemmschiene geschlossen wird.In the so-called immersion position, the clamping elements can dip into the thread layer from one side. If they are pivoted into the clamping position after passing through the thread layer, then they grip around the thread layer from the other side and, together with the clamping rail, form a clamping gap which is closed when the clamping elements move back to the clamping rail.
Da bei der erfindungsgemässen Klemmvorrichtung nur ein einziges Organ relativ zur Fadenschicht bewegt werden muss, welches ausserdem relativ einfach mit den für den Klemmvorgang erforderlichen Antriebsmitteln ausgerüstet werden kann, ergibt sich eine einfachere Handhabung und eine grössere Automatisierungsfreundlichkeit als bei den bekannten Klemmvorrrichtungen.Since in the clamping device according to the invention only a single organ has to be moved relative to the thread layer, which can also be equipped relatively easily with the drive means required for the clamping process, this results in easier handling and greater automation friendliness than in the known clamping devices.
Die Erfindung betrifft weiter eine Verwendung der genannten Klemmvorrichtung zum Klemmen einer Kettfadenschicht.The invention further relates to the use of said clamping device for clamping a warp thread layer.
Diese Verwendung ist gekennzeichnet durch folgende Massnahmen:
- a. Positionierung der Klemmvorrichtung an einer Seite, ober- oder unterhalb, der Fadenschicht;
- b. Bewegung der Klemmvorrichtung mit den Klemmelementen des Klemmorgans in Eintauchstellung gegen die Fadenschicht bis zum Durchtritt der Klemmelemente durch diese;
- c. Verstellung der Klemmelemente in ihre Klemmstellung und' Rückbewegung gegen die Klemmschiene zur Schliessung des zwischen Klemmelementen und Klemmschiene gebildeten, die Fadenschicht zu beiden Seiten umfassenden Klemmspalts.
- a. Positioning of the clamping device on one side, above or below the thread layer;
- b. Movement of the clamping device with the clamping elements of the clamping member in the immersion position against the thread layer until the clamping elements pass through it;
- c. Adjustment of the clamping elements in their clamping position and 'return movement against the clamping rail to close the clamping gap formed between the clamping elements and the clamping rail and comprising the thread layer on both sides.
Die Erfindung ist in den Ansprüchen 1-12 dargelegt.The invention is set out in claims 1-12.

Die Fig. 1 und 2 zeigen eine Vorder- und eine Seitenansicht einer erfindungsgemässen Klemmvorrichtung, welche darstellungsgemäss aus einer Klemmschiene 1 und aus einem durch nebeneinander angeordnete Klemmelemente Kl bis Kn gebildeten Klemmorgan besteht. Die Klemmvorrichtung dient zum Klemmen von flächigen Fadenschichten FS, insbesondere von Kettfäden und dergleichen. Die einzelnen die Fadenschicht FS bildenden Fäden verlaufen in Fig. 1 senkrecht zur Zeichenebene und in Fig. 2 horizontal, also quer über das Zeichenblatt, und sie sind in der Regel dicht nebeneinander angeordnet.1 and 2 show a front and a side view of a clamping device according to the invention, which according to the illustration is formed by a clamping rail 1 and by a clamping element Kl to Kn arranged next to one another Clamping element exists. The clamping device is used to clamp flat thread layers FS, in particular warp threads and the like. The individual threads forming the thread layer FS run perpendicular to the drawing plane in FIG. 1 and horizontally, that is to say transversely across the drawing sheet, in FIG. 2, and they are generally arranged closely next to one another.
Wie schon eingangs erwähnt wurde, ist die erfindungsgemässe Klemmvorrichtung eine "einseitige", bei der das zu klemmende Gut, also die Fadenschicht FS nur an einer Seite zugänglich zu sein braucht. Diese Seite ist bezogen auf die Fig. 1 und 2 die obere Seite der Fadenschicht FS; es kann aber je nach den räumlichen Gegebenheiten auch die untere, oder bei einer vertikalen Fadenschicht die linke oder die rechte oder die hintere oder die vordere Seite sein. Wesentlich ist, dass die Klemmvorrichtung an dieser einen Seite der Fadenschicht FS positioniert wird, wodurch die Lage der Klemmschiene 1 an dieser einen Seite festgelegt ist. Nun müssen die relativ zur Klemmschiene 1 beweglichen Klemmelemente zur Bildung eines Klemmspalts an die andere Seite der Fadenschicht FS gebracht und schliesslich muss der Klemmspalt geschlossen werden.As already mentioned at the beginning, the clamping device according to the invention is a "one-sided", in which the material to be clamped, that is to say the thread layer FS, only needs to be accessible on one side. This page is based on FIGS. 1 and 2 the upper side of the thread layer FS; However, depending on the spatial conditions, it can also be the lower side or, in the case of a vertical layer of thread, the left or the right or the rear or the front side. It is essential that the clamping device is positioned on this one side of the thread layer FS, as a result of which the position of the clamping rail 1 is fixed on this one side. Now the clamping elements movable relative to the clamping rail 1 have to be brought to the other side of the thread layer FS to form a clamping gap and finally the clamping gap has to be closed.
Darstellungsgemäss bestehen die Klemmelemente Kl bis Kn im wesentlichen aus einem an der Klemmschiene 1 hubverschiebbar gelagerten Bolzen 2, welcher mit seinem einen Ende aus der Klemmschiene 1 ragt und an diesem Ende einen flügelartigen Klemmteil 3 trägt. Dieser ist durch eine relativ dünne, gegen ihr freies Ende sowohl in der Länge als auch in der Dicke zugespitzte Lamelle gebildet, welche annähernd die Form eines gleichschenkeligen, an seiner Basis vom Bolzen 2 getragenen Dreiecks aufweist. Die Länge dieser Basis ist grösser als der Abstand benachbarter Bolzen 2.According to the illustration, the clamping elements Kl to Kn essentially consist of a
Wenn nun die Klemmvorrichtung an der einen Seite der Fadenschicht FS positioniert ist und eine Klemmung erfolgen soll, werden die Klemmteile 3 so ausgerichtet, dass sie parallel zu den die Fadenschicht FS bildenden Fäden verlaufen; sie werden also gegenüber der in den Fig. 1 und 2 dargestellten Lage um 90° verdreht. In dieser Lage können die Klemmteile 3 die Fadenschicht FS problemlos durchstossen. Anschliessend werden sie um 90° zurückgeschwenkt und nehmen die in den Figuren dargestellte Lage ein, in der sie ein zusammenhängendes Klemmorgan bilden und zusammen mit der Klemmschiene 1 einen über die Breite der Fadenschicht FS reichenden Klemmspalt begrenzen.If the clamping device is now positioned on one side of the thread layer FS and is to be clamped, the
Die einzelnen Bolzen 2 sind im Bereich ihres Mittelteils mit einem Auflagering oder einer Auflagelatte 4 fest verbunden, mit welcher sie auf einem von der Klemmschiene 1 getragenen Halteorgan 5 abgestützt sind. Die Klemmschiene 1 weist in ihrem Querschnitt eine entsprechende Formgebung, beispielsweise ein C-förmiges Profil mit einem Boden 6, einer Deckwand 7 und einer Rückwand 8, auf. Zwischen den Auflageringen 4 und der Deckwand 7 wirken Druckfedern 9, die den Auflagering 4 gegen das Halteorgan 5 und damit die Klemmelemente Kl bis Kn nach unten drücken.The
Wie insbesondere Fig. 3, welche eine Detailansicht in Richtung des Pfeiles III von Fig. 1 zeigt, zu entnehmen ist, erfolgt die Verdrehung oder Verschwenkung der Bolzen 2 und der Klemmteil 3 durch einen sich über die Länge der Klemmschiene 1 erstreckenden, stangenartigen Schieber 10, welcher mit an den einzelnen Bolzen 2 befestigten Verstellarmen 11 gelenkig verbunden ist. Durch in der Klemmschiene 1 angeordnete Anschlagelemente 12 ist der Verstellweg des Schiebers 10 so begrenzt, dass die Klemmteile 3 zwischen den beiden Positionen parallel und senkrecht zu den Fäden verschwenkt werden. In Fig. 3 ist die Klemmstellung der Klemmelemente Kl bis Kn und der Verstellarme 11 voll und die Eintauchstellung gestrichelt eingezeichnet.As can be seen in particular from FIG. 3, which shows a detailed view in the direction of arrow III of FIG. 1, the
Selbstverständlich ist die beschriebene Lösung des Schwenkantriebs der Bolzen 2 mittels Schieber 10 und Verstellarmen 11 nur ein Ausführungsbeispiel. Eine andere Möglichkeit besteht darin, die Auflageringe 4 an ihrem Umfang mit einer Verzahnung zu versehen und den Schieber 10 durch eine mit dieser Verzahnung in Eingriff stehende Zahnstange zu ersetzen. Auch die Ausbildung der Klemmteile 3 ist als beispielhaft zu verstehen.Of course, the described solution of the swivel drive of the
Diese könnten auch durch einen Bügel aus gebogenem Draht oder dergleichen gebildet sein.These could also be formed by a bow made of bent wire or the like.
Da, wie schon erwähnt, die Länge der Klemmteile 3 an ihrer Basis grösser ist als die Teilung der Bolzen 2, überlappen die Klemmteile 3 einander in ihrer Klemmstellung um einige Millimeter. Damit das durch die Klemmteile 3 der einzelnen Elemente Kl bis Kn gebildete Klemmorgan eine möglichst glatte Oberfläche ohne seitlich vorstehende Kanten oder Ecken aufweist, sind die Klemmteile in ihrem Ueberlappungsbereich entsprechend abgestuft ausgebildet. Die mit A bezeichneten Abstufungen sind besonders aus Fig. 3 ersichtlich.Since, as already mentioned, the length of the
Das Halteorgan 5 ist durch je zwei parallele, zu beiden Seiten entlang der Bolzen 2 angeordnete und je eine erste und eine zweite Zahnstange 13 bzw. 14 enthaltende Zanhstangenpaare gebildet. Die ersten Zahnstangen 13, welche als Auflage für die Auflageringe 4 und damit für die Klemmelemente Kl bzw Kn dienen, sind an ihrer Auflagekante für die Auflageringe 4 eben und weisen an ihrer unteren Kante eine Verzahnung auf. Ausserdem sind sie in der Klemmschiene 1 so angeordnet, dass sie nur eine Vertikalbewegung durchführen können.The holding
Die zweiten Zahnstangen 14 weisen ebenfalls eine gerade und eine mit einer Verzahnung versehene Kante auf. Die gerade Kante dient als Auflagefläche auf dem Boden 6 der Klemmschiene 1, und die Verzahnung an der anderen Kante steht in Eingriff mit der Verzahnung der ersten Zahnstangen 13. Die zweiten Zahnstangen 14 sind in der Klemmschiene 1 so angeordnet, dass sie nur eine horizontale Verstellbewegung in Längsrichtung der Klemmschiene 1 durchführen können. Diese Verstellung erfolgt durch geeignete Mittel, beispielsweise durch eine zwischen der Klemmschiene 1 und den zweiten Zahnstangen 14 wirkende Schraube 15 (Fig. 1) oder durch einen Exzenter, einen Kniehebel, durch hydraulische Mittel oder durch Pressluft.The second racks 14 also have a straight edge and a toothed edge. The straight edge serves as a contact surface on the
Bei dem in Fig. 1 dargestellten Zustand ist der Klemmspalt geöffnet und die Klemmteile 3 haben maximalen Abstand von der Klemmschiene 1. Zur Schliessung des Klemmspalts und zum Festklemmen der Fadenschicht FS wird nun die Schraube 15 so gedreht, dass sich die zweiten Zahnstangen 14 nach links bewegen. Dadurch werden die ersten Zahnstangen 13 und damit über die Auflageringe 4 auch die Klemmelemente Kl bis Kn gegen die Kraft der Federn 9 angehoben.In the state shown in FIG. 1, the clamping gap is open and the
Die Klemmschine 1 ist an ihrer den Klemmspalt mitbildenden Auflagefläche für die Fadenschicht FS mit einer elastischen Auflage 16 aus geeignetem Material, beispielsweise aus Gummi, versehen. Zur Erhöhung der Klemmwirkung kann an der Klemmstelle eine Fadenumlenkung erfolgen, wozu die Klemmschiene 1 entlang der Klemmlinie eine Nut 17 (Fig. 2) aufweisen kann. In diesem Fall könnte die Auflage 16 weggelassen werden. Eine weitere Variante würde darin bestehen, diese Nut breiter und tiefer auszuführen und mit einer elastischen Einlage zu versehen.The clamping rail 1 is provided on its supporting surface for the thread layer FS which forms the clamping gap with an
Die beschriebene einseitige Klemmvorrichtung ist besonders bei der sogenannten Kettvorbereitung, das ist beim Einziehen und beim Anknüpfen von Webketten, einsetzbar und zeigt sich den konventionellen zweiseitigen Klemmvorrichtungen speziell bei beengten Platzverhältnissen, wie sie beispielsweise beim Einsatz an der Webmaschine vorliegen, überlegen.The described one-sided clamping device can be used especially in the so-called warp preparation, that is when pulling in and tying in warps, and is superior to the conventional two-sided clamping devices, especially when space is limited, such as when used on the weaving machine.
Wie die Beschreibung der Klemmvorrichtung zeigt, erfordert ihr Einsatz und Betrieb nur wenige Manipulationen, und zwar:
- Positionierung an der betreffenden Fadenschicht FS
- Betätigung des
Schiebers 10 Betätigung der Schraube 15.
- Positioning on the relevant thread layer FS
- Actuation of the
slide 10 - Actuation of
screw 15.
Diese Maniuplationen können einfach automatisiert werden, so dass also die erfindungsgemässe Klemmvorrichtung einen wesentlichen Schritt in Richtung Rationalisierung und Automatisierung beim Einziehen und Anknüpfen von Webketten ermöglicht.These manipulations can be easily automated, so that the clamping device according to the invention enables an essential step in the direction of rationalization and automation in the drawing in and weaving of warps.
