Definitions
- the invention relates to a warp knitting machine with at least one pattern guide having a plurality of thread guides, which are reciprocated in the offset direction by a drive, wherein the drive acts on the thread guide via a tension element loaded only on train.
- Such a warp knitting machine is made DE 41 14 012 C2 known.
- the thread guides are connected via pull cables with a drive motor.
- the thread guides are hinged to a bar carrier. The movement of the traction cable therefore translates into a pivoting movement of the thread guide.
- stops are provided which limit the pivoting angle of the end of the yarn guide on which the guide eye is arranged. If this end abuts against the stop, then the second lever of the thread guide can deform.
- US Pat. No. 3,303,670 A shows a part of a warp knitting machine, in which a plurality of yarn guide against knitting needles are movable.
- Each yarn guide is designed as a perforated needle, which has a shaft and a right angle bent portion. The bent portion is inserted into a needle holder which is attached to a rod.
- the rod is movable over a pattern chain and a plunger assembly. The rod is driven only at one end and is not held at the other end.
- the thread guides are held in grooves in the needle holder. The grooves are covered by a plate.
- DE 24 36 452 B1 shows a warp knitting machine with weft device, are set in the yarn guide, which are designed as hollow needles in mutually displaceable strips. If the strips are shifted against each other, then groups of thread guides are shifted against each other.
- the invention has for its object to provide a reliable motion control of the yarn guide with a simple structure.
- each yarn guide is T-shaped and has a substantially extending in the offset direction holding part, which is arranged substantially perpendicular to a shaft and rigidly connected to the shaft, wherein the holding part is determined over a length on the tension element.
- the thread guides are T-shaped, ie they have a shank, at the lower end of which the thread guide eyelet is arranged is.
- the upper end of the shaft is rigidly connected to a holding part. This rigid connection means that even with rapid movements of the thread guide basically no articulated movements between the shaft and the holding part occur. The movement of the holding part is thus transmitted directly to the movement of the yarn guide eyelet.
- the holding part Since the holding part has a certain extent in the offset direction, the holding part is supported over a certain length on the tension element, ie by the connection of the holding part with the tension element, it is possible torques that can be initiated via the forces acting on the shaft, in certain To take limits. This results in an extremely stable attachment of the thread guide on the tension element. This in turn has the consequence that, as stated above, the tension element can be dimensioned with relatively low weight. Since this reduces the moving masses, the working speed of the warp knitting machine can be increased.
- the tension element is designed as a wire or rope.
- a wire or rope can transmit substantial tensile forces while compressive forces are virtually non-transferable. While it is necessary for this purpose to hold the wire or rope at both ends or to apply forces.
- a motion control in which elements can be pulled from both sides is known per se. You can either use restoring devices at one end or return the wire or rope via a pulley to the drive.
- a great advantage of using a wire or a rope is that such a tension element a has small weight and takes up little space, so that you can arrange a plurality of tension elements side by side and thus can control a corresponding plurality of yarn guides in different ways.
- the shaft has a cross section which is smaller than the cross section of the holding part.
- the thread guide is stabilized, which turns out to be advantageous especially at higher speeds.
- the assignment between the tension element and the thread guide is maintained due to the larger cross-section of the holding part with high reliability and especially against moments that act on the thread guide.
- the length of the shaft is smaller than twice the length of the holding part. This leaves moments on the holding part within a reasonable range.
- the holding part has a clamping device with which the thread guide is clamped attached to the tension element.
- This embodiment has advantages especially if you want to change the position of the thread guide on the tension element, for example, to set a new repeat or a new pattern. For this purpose, it is only necessary to release the clamping device and to move the tension member and the holding member relative to each other. Then, when the clamping device is fixed again, the thread guide is fixed in the desired position.
- the holding part and the tension element are glued together.
- the element and the holding part are virtually inseparable connected to each other, so that changes in the position of the holding part on the tension element after bonding practically can not be effected. If a change in the position of the holding part on the tension element is required, for example by changing the repeat, then you may have to use a new tension element and new thread guide.
- the design has the advantage that the production of the yarn guide is very easy. It is not necessary to take constructive measures in order to fasten the clamping element, for example a screw.
- the holding part has a recess in which the tension element is inserted, wherein the recess is at least partially filled with a fixing compound.
- a fixing compound for example, it is possible to insert the tension element into the recess, which can be in the form of an open groove, then to inject an adhesive and cure it, for example by using UV radiation.
- the recess can therefore be open, which saves material on the holding part.
- the plastic used for bonding can be relatively light.
- a plurality of yarn guides are provided, the holding parts are arranged parallel to each other and in the direction of their shafts one above the other, wherein the shafts have different lengths. Due to the different lengths of the shafts, it is possible that the guide eyelets of all yarn guides can be arranged on an imaginary line. Nevertheless, it is possible that individual thread guides can be controlled individually within certain limits.
- longer shanks widen at the end connected to the support member. This means that the same rigidity can be achieved with the longer thread guides as with the shorter thread guides. Although the broadening can lead to the need for more space in the attachment of the longer thread guide to the tension element. However, this is not critical, because one can leave the widenings, if necessary, triangular over the group of yarn guides.
- the holding part is arranged in a groove in a billet carrier.
- the groove in which the yarn guides are held with very little play, additionally serves to stabilize the movement of the yarn guides.
- a movement is basically only possible parallel to the extension of the groove. This is another measure to catch moments that could be exerted on the shaft via the shaft. Due to the rigid connection between the shaft and the holding part, which can be achieved for example by welding or soldering the shaft to the holding part or by a one-piece design of these two parts, it is achieved that the shaft is moved with the same kinematics, as the holding part.
- the holding part is guided with the interposition of sliding shoes in the groove.
- the thread guide or its holding part has no direct contact with the surfaces of the groove. This contact can be made via the sliders, which produce a small distance between the holding part and the groove and can be formed from a material which interacts with the material of the billet carrier with as little friction as possible. Well suited to this are usually plastics.
- the shoes are also designed as wearing parts, so that you can achieve a long life of the thread guide and the associated barre by replacing the shoes.
- the shoes are attached to the tension element.
- This training has two advantages. On the one hand results in a support of the holding part in the groove in the largest possible distance. On the other hand it is also prevented that the tension element rubs against the walls of the groove.
- the sliding shoes are U-shaped and clipped onto the tension element and / or glued.
- the positioning of the shoes is then, as I said, close to the two ends of the holding part.
- the clipping is a connection that solved quickly can be.
- additional stabilization can result from a permanent bond such as sticking.
- the billet carrier on a cover.
- the cover covers the groove and beyond an area in which the shaft of the thread guide extends.
- the cover thus leads to an increase in the transverse stability.
- the cover may be made of or coated with sliding material.
- two bar carriers abut each other with the interposition of the cover with their sides having the groove.
- a relatively thin intermediate plate with good sliding property is sufficient because the thread guides support each other, so not only do not hinder their movement, but even increase the stability.
- the tension member is provided at at least one end with a thread engageable with a drive member.
- the tension elements ie wires or ropes
- the tension elements at their ends must not have thick points or eyes that no longer fit through the groove. It is therefore possible to provide the tension elements with threads on at least one side.
- the thread allows a solid and space-saving connection with the drive of the tension element (or with a corresponding clamping device on the other side). But it allows after removing the drive or the tensioning device that the tension element out of the groove is pulled out.
- Fig. 1 shows a Musterlegebarre 1 with several groups 2, 3 of yarn guides 4. Mutually corresponding yarn guide 4 of each group 2, 3, ie each of the first, second, third, etc. yarn guide 4 of each group 2, 3, are driven together, ie can be moved relative to a bar carrier 5 in an offset direction 6, which is characterized by a double arrow, with means not shown are provided with which the bar carrier 5 is also movable in the offset direction 6.
- tension elements 7 are provided, which are designed as wire or wire rope, so have a relatively small cross-section.
- the tension elements 7 are what, with reference to the following Fig. 2 and 4 will be explained in more detail, arranged transversely to the offset direction 6 one above the other.
- Each tension element 7 is connected via a drive belt 8 with a drive motor 9 in connection, wherein the drive belt 8 is fixed at its other end in a clamping element 10, which is designed as a single-acting pneumatic cylinder.
- the clamping element 10 is acted upon via a pressure source P with pressure.
- the other end of the tension element 7 is connected to a tension band 11, which is guided over a deflection roller 12 and is likewise fixed in a tensioning element 13.
- the tensioning element 13, which is also considered simple acting compressed air cylinder is supplied from a pressure source P1 with compressed air.
- the pressures of the pressure sources P, P1 and the effective pressure application surfaces of the clamping elements 10, 13 are coordinated so that the same force is exerted on both ends of the tension element 7.
- the drive motor 9 therefore only has to apply forces which are required for the movement of the tension element 7. However, he does not have to apply forces that are required to tension a spring or other tensioning device.
- Fig. 2 It now shows the closer structure of the pattern guide 1. It can be seen that in a yarn guide group 2, 3 eight yarn guides 4 are arranged. The yarn guides 4 are arranged in the offset direction 6 side by side and are driven by tension elements 7, which are arranged transversely to the offset direction 6 one above the other. A yarn guide 4 will now be related to Fig. 3 described.
- the yarn guide 4 has a shaft 14, at the lower end of a yarn guide eye 15 is arranged, which is located in a hole needle 16 which is fixed in the shaft 14.
- the upper part of the shaft 14 is fixedly connected to a holding part 17, so welded or soldered or the shaft 14 is formed integrally with the holding part 17.
- the holding part 17 has a longitudinal bore through which the tension element 7 is guided.
- a clamping screw 18 in the holding part 17 serves to clamp the holding part 17 on the tension element 7. If you solve the clamping screw 18, you can hold the holding part on the Move tension element 7 in the offset direction 6 and set at another position by tightening the clamping screw 18 again.
- the sliding shoes 19, 20 are arranged at the two ends of the holding part 17 .
- the sliding shoes 19, 20 have a U-shaped cross section. They are clipped onto the tension element 7 and may optionally be fixed there with an adhesive, the adhesive mainly having the task of causing the sliding shoes 19, 20 to be fixed at the ends of the holding part 17 during operation. If a shift of the thread guide 4 on the tension element 7 is required, then you can by simply bending the sliding blocks 19, 20 a release of the shoes 19, 20 reach from the tension member 7, so that the yarn guide 4 can be moved to a new position.
- the holding parts 17 are arranged in grooves 21 and that with a relatively small clearance.
- the sliding blocks 19, 20 are adapted to the grooves 21, that a contact between the holding part 17 and the billet carrier 5 basically does not take place. At the same time prevent the shoes 19, 20 also that the tension element 7 gets in contact with the billet carrier and rubs against it.
- the side of the billet carrier 5, in which the grooves 21 open, is covered by a cover 22.
- the cover 22 is preferred so far in the direction of the thread guide eye 15 that it also covers a relatively large part of the shaft 14 with.
- the cover 22 may be secured, for example by means of a screw 23 on the bar support 5, so that the cover 22 can be removed when individual yarn guide 4 to be serviced, replaced, removed or supplemented.
- Fig. 5 shows a modified embodiment in which two bar carriers 5a, 5b are provided. Both bar carriers 5 a, 5 b lie with the interposition of the cover 22 together with the side into which the grooves 21 open.
- the cover 22 is relatively flexible, ie it can be relatively thin. This allows the individual yarn guides 4 on the two bar carriers 5a, 5b in the transverse direction 24 stabilize each other, even if they are moved in the direction of offset 6 relative to each other. The cover 22 then ensures that yarn guides of the billet carrier 5a can not collide with yarn guides of the billet carrier 5b.
- the cover 22 may be made of a sliding material, such as a plastic, or be coated with such. In the case ofReglegebarre after Fig. 4 for example, the cover 22 should have some mechanical stability to provide transverse stability.
- the tension elements 7 must have no thick spots or loops at their ends.
- the tension elements 7 are therefore provided at least at one end with an external thread 25 to which a drawbar eye 26 can be screwed, in which the drive belt 8 or the tension band 11 can be hung.
- Fig. 7 now shows a situation in which all yarn guides 4 abut each other in the offset direction 6. It can be seen that the yarn guides 4a, whose holding part 17a is arranged in the lowermost groove, have a shorter shaft 14a than the yarn guides 4b, whose holding parts 17b are arranged in the uppermost groove. The shaft 14b of such a thread guide is much longer.
- this widening 27 requires slightly more installation space in the offset direction. However, this is not critical, because the widening 27 may also be angled relative to the shank 14b, so that the widenings 27 overall may have the shape of a triangle.
- the length of the shaft H should be at most twice the length of the holding part 17. It is also advantageous if the cross section of the shank 14 outside the reinforcement 27 is smaller than the cross section of the holding part 17.
- the clamping elements 10, 13 may be formed as a glass tube with graphite piston.
- the graphite pistons run in glass at least approximately wear-free. The glass bulbs do not blow up and have a relatively small loss of air.
- the biasing properties are not length-dependent, as would be the case, for example, if one would use a spring as a tensioning device. Accordingly, the drive motor 9 need only apply the force required to drive the yarn guides 4, but not the force required to tension a return device.
- the elements used to drive the thread guide namely the tension element 7, the drive belt 8, the tension band 11 and the sliding blocks 19, 20 are of relatively low mass, so that you can achieve relatively high accelerations and thus operating frequencies with the illustrated construction.
- Fig. 8 shows an alternative embodiment of a yarn guide, in which parts corresponding to those of Fig. 3 are provided with reference numbers increased by 100.
- the holding part 117 now has a groove 29 extending in the offset direction 6, which groove is open on one side. How out Fig. 8a can be seen, the tension element 7 is inserted into this groove 29 and fixed by means of a fixing compound 28, such as an adhesive.
- a fixing compound 28 such as an adhesive.
- the attachment of the holding part 117 on the tension element is thus accomplished simply by inserting the tension element 7 in the groove 29, injects the fixing compound 28 and then allowed to cure, for example, using UV radiation. It is not necessary that the fixing compound 28 fills the entire groove 29. It is also possible to limit the adhesive bond between the tension element 7 and the holding part 117 to certain lengths.
- the remaining parts for example, the sliding blocks 19, 20, can also in the in Fig. 8 used thread guide can be used.
- FIG. 3 illustrates the working area 37 of a warp knitting machine, to which knitting needles 38 with sliders 39, a piercing comb 40 and a teetering comb 41 belong.
- the product is removed via a take-off roller 42.
- the guide bar 43 leads to basic threads, the guide bar 44 picot threads.
- This is followed by six bar supports 45, 46, 47, 48, 49, 50, each of four to twelve pattern laying bars in the form of associated with the Fig. 1 to 4 described construction included.
- This is followed by two Jaquard guide bars 51, 52 and another guide bar 53 for staple threads.
- the bar carriers of the guide bars 45 - 50 are arranged in pairs and lie with their sides together, in which the grooves 21 are arranged.

Description
Die Erfindung betrifft eine Kettenwirkmaschine mit mindestens einer Musterlegebarre, die mehrere Fadenführer aufweist, die in Versatzrichtung durch einen Antrieb hin- und herbewegbar sind, wobei der Antrieb über ein lediglich auf Zug belastetes Zugelement auf die Fadenführer wirkt.The invention relates to a warp knitting machine with at least one pattern guide having a plurality of thread guides, which are reciprocated in the offset direction by a drive, wherein the drive acts on the thread guide via a tension element loaded only on train.
Eine derartige Kettenwirkmaschine ist aus
Während im letzten Fall eine relativ zuverlässige Bewegungssteuerung der Fadenführer möglich ist, dies aber mit einer relativ schwerfälligen Konstruktion erkauft wird, ist im ersten Fall eine Schwingungsneigung der Fadenführer zu beobachten.While in the latter case, a relatively reliable motion control of the yarn guide is possible, but this is paid for with a relatively heavy construction, in the first case a tendency to oscillation of the yarn guide is observed.
Der Erfindung liegt die Aufgabe zugrunde, bei einem einfachen Aufbau eine zuverlässige Bewegungssteuerung der Fadenführer zu ermöglichen.The invention has for its object to provide a reliable motion control of the yarn guide with a simple structure.
Diese Aufgabe wird bei einer Kettenwirkmaschine der eingangs genannten Art dadurch gelöst, daß jeder Fadenführer T-förmig ausgebildet ist und ein im wesentlichen in Versatzrichtung verlaufendes Halteteil aufweist, das im wesentlichen senkrecht zu einem Schaft angeordnet und mit dem Schaft starr verbunden ist, wobei das Halteteil über eine Länge am Zugelement festgelegt ist.This object is achieved in a warp knitting machine of the type mentioned above in that each yarn guide is T-shaped and has a substantially extending in the offset direction holding part, which is arranged substantially perpendicular to a shaft and rigidly connected to the shaft, wherein the holding part is determined over a length on the tension element.
Mit dieser Ausgestaltung ist es möglich, Zugelemente zu verwenden, die einen relativ kleinen Querschnitt haben. Diese Zugelemente werden lediglich auf Zug belastet und müssen keine Druckkräfte aushalten. Um damit die Bewegung der Fadenführer, genauer gesagt der Führungsösen der Fadenführer, steuern zu können, sind die Fadenführer T-förmig ausgebildet, d.h. sie weisen einen Schaft auf, an dessen unterem Ende die Fadenführungsöse angeordnet ist. Das obere Ende des Schaftes ist starr mit einem Halteteil verbunden. Diese starre Verbindung bedeutet, daß auch bei schnellen Bewegungen des Fadenführers im Grunde keine gelenkigen Bewegungen zwischen dem Schaft und dem Halteteil auftreten. Die Bewegung des Halteteils wird also direkt auf die Bewegung der Fadenführungsöse übertragen. Da das Halteteil eine gewisse Erstreckung in Versatzrichtung aufweist, ist das Halteteil über eine gewisse Länge an dem Zugelement abgestützt, d.h. durch die Verbindung des Halteteils mit dem Zugelement ist es möglich, Drehmomente, die über die am Schaft angreifenden Kräfte eingeleitet werden können, in gewissen Grenzen aufzunehmen. Es ergibt sich also eine außerordentlich stabile Befestigung der Fadenführer am Zugelement. Dies wiederum hat zur Folge, daß, wie oben ausgeführt, das Zugelement mit relativ geringem Gewicht dimensioniert werden kann. Da sich damit die bewegten Massen verringern, läßt sich die Arbeitsgeschwindigkeit der Kettenwirkmaschine erhöhen.With this configuration, it is possible to use tension elements that have a relatively small cross-section. These tension elements are loaded only on train and must not bear pressure forces. In order to be able to control the movement of the thread guides, more precisely the guide eyes of the thread guides, the thread guides are T-shaped, ie they have a shank, at the lower end of which the thread guide eyelet is arranged is. The upper end of the shaft is rigidly connected to a holding part. This rigid connection means that even with rapid movements of the thread guide basically no articulated movements between the shaft and the holding part occur. The movement of the holding part is thus transmitted directly to the movement of the yarn guide eyelet. Since the holding part has a certain extent in the offset direction, the holding part is supported over a certain length on the tension element, ie by the connection of the holding part with the tension element, it is possible torques that can be initiated via the forces acting on the shaft, in certain To take limits. This results in an extremely stable attachment of the thread guide on the tension element. This in turn has the consequence that, as stated above, the tension element can be dimensioned with relatively low weight. Since this reduces the moving masses, the working speed of the warp knitting machine can be increased.
Vorzugsweise ist das Zugelement als Draht oder Seil ausgebildet. Ein Draht oder ein Seil kann im wesentlichen Zugkräfte übertragen, während Druckkräfte praktisch nicht übertragbar sind. Es ist zu diesem Zweck zwar erforderlich, den Draht oder das Seil an beiden Enden zu halten bzw. mit Kräften zu beaufschlagen. Eine Bewegungssteuerung, bei der Elemente von beiden Seiten aus gezogen werden können, ist an sich aber bekannt. Man kann hierzu entweder Rückstelleinrichtungen an einem Ende verwenden oder den Draht oder das Seil über eine Umlenkrolle zum Antrieb zurückführen. Ein großer Vorteil bei der Verwendung eines Drahtes oder eines Seiles liegt darin, daß ein derartiges Zugelement ein kleines Gewicht hat und nur wenig Platz beansprucht, so daß man eine Mehrzahl von Zugelementen nebeneinander anordnen und damit eine entsprechende Vielzahl von Fadenführern auf unterschiedliche Weise steuern kann.Preferably, the tension element is designed as a wire or rope. A wire or rope can transmit substantial tensile forces while compressive forces are virtually non-transferable. While it is necessary for this purpose to hold the wire or rope at both ends or to apply forces. A motion control in which elements can be pulled from both sides is known per se. You can either use restoring devices at one end or return the wire or rope via a pulley to the drive. A great advantage of using a wire or a rope is that such a tension element a has small weight and takes up little space, so that you can arrange a plurality of tension elements side by side and thus can control a corresponding plurality of yarn guides in different ways.
Bevorzugterweise weist der Schaft einen Querschnitt auf, der kleiner ist als der Querschnitt des Halteteils. Damit wird der Fadenführer stabilisiert, was sich insbesondere bei höheren Bewegungsgeschwindigkeiten als vorteilhaft herausstellt. Die Zuordnung zwischen dem Zugelement und dem Fadenführer wird aufgrund des größeren Querschnitts des Halteteils mit hoher Zuverlässigkeit beibehalten und zwar vor allem auch gegen Momente, die auf den Fadenführer wirken.Preferably, the shaft has a cross section which is smaller than the cross section of the holding part. Thus, the thread guide is stabilized, which turns out to be advantageous especially at higher speeds. The assignment between the tension element and the thread guide is maintained due to the larger cross-section of the holding part with high reliability and especially against moments that act on the thread guide.
Auch ist es günstig, wenn die Länge des Schaftes kleiner ist als das Doppelte der Länge des Halteteils. Damit bleiben Momente auf das Halteteil in einem vertretbaren Bereich.It is also advantageous if the length of the shaft is smaller than twice the length of the holding part. This leaves moments on the holding part within a reasonable range.
Vorzugsweise weist das Halteteil eine Klemmeinrichtung auf, mit der der Fadenführer klemmend am Zugelement befestigt ist. Diese Ausgestaltung hat vor allem dann Vorteile, wenn man die Position des Fadenführers auf dem Zugelement ändern möchte, beispielsweise um einen neuen Rapport oder ein neues Muster einzustellen. Hierzu ist es lediglich erforderlich, die Klemmeinrichtung zu lösen und das Zugelement und das Halteteil relativ zueinander zu verschieben. Wenn dann die Klemmeinrichtung wieder festgelegt wird, ist der Fadenführer in der gewünschten Position befestigt.Preferably, the holding part has a clamping device with which the thread guide is clamped attached to the tension element. This embodiment has advantages especially if you want to change the position of the thread guide on the tension element, for example, to set a new repeat or a new pattern. For this purpose, it is only necessary to release the clamping device and to move the tension member and the holding member relative to each other. Then, when the clamping device is fixed again, the thread guide is fixed in the desired position.
In einer bevorzugten Ausführungsform ist vorgesehen, daß das Halteteil und das Zugelement miteinander verklebt sind. Damit sind zwar das Element und das Halteteil quasi unlösbar miteinander verbunden, so daß Änderungen der Position des Halteteils am Zugelement nach dem Verkleben praktisch nicht mehr bewirkt werden können. Wenn eine Änderung der Position des Halteteils am Zugelement erforderlich ist, beispielsweise durch Wechsel des Rapports, dann muß man unter Umständen ein neues Zugelement und neue Fadenführer verwenden. Die Ausgestaltung hat aber den Vorteil, daß die Fertigung der Fadenführer sehr einfach wird. Man muß keine konstruktiven Maßnahmen treffen, um das Klemmelement, beispielsweise eine Schraube, befestigen zu können. Darüber hinaus ist es möglich, Gewicht einzusparen, so daß die Arbeitsgeschwindigkeit der Kettenwirkmaschine erhöht oder die Beanspruchung der Steuerungsglieder vermindert werden kann.In a preferred embodiment it is provided that the holding part and the tension element are glued together. Thus, although the element and the holding part are virtually inseparable connected to each other, so that changes in the position of the holding part on the tension element after bonding practically can not be effected. If a change in the position of the holding part on the tension element is required, for example by changing the repeat, then you may have to use a new tension element and new thread guide. However, the design has the advantage that the production of the yarn guide is very easy. It is not necessary to take constructive measures in order to fasten the clamping element, for example a screw. In addition, it is possible to save weight, so that the operating speed of the warp knitting machine can be increased or the load of the control members can be reduced.
Hierbei ist besonders bevorzugt, daß das Halteteil eine Ausnehmung aufweist, in der das Zugelement eingelegt ist, wobei die Ausnehmung zumindest teilweise mit einer Fixiermasse gefüllt ist. Man kann beispielsweise das Zugelement in die Ausnehmung, die als offene Nut ausgebildet sein kann, einlegen, danach einen Klebstoff einspritzen und diesen aushärten, beispielsweise unter der Verwendung von UV-Strahlung. Die Ausnehmung kann daher offen sein, was Material am Halteteil einspart. Der Kunststoff, der zum Kleben verwendet wird, kann relativ leicht sein. Mit "Kleben" sollen hierbei alle Verbindungsarten verstanden werden, durch die eine dauerhafte Verbindung zwischen dem Halteteil und dem Zugelement geschaffen wird. Diese Verbindung kann mit oder ohne Hilfsstoffe erzeugt werden.It is particularly preferred that the holding part has a recess in which the tension element is inserted, wherein the recess is at least partially filled with a fixing compound. For example, it is possible to insert the tension element into the recess, which can be in the form of an open groove, then to inject an adhesive and cure it, for example by using UV radiation. The recess can therefore be open, which saves material on the holding part. The plastic used for bonding can be relatively light. By "gluing" in this case all types of connection should be understood, by a permanent connection between the holding part and the tension element is created. This compound can be generated with or without auxiliaries.
Vorzugsweise sind mehrere Fadenführer vorgesehen, deren Halteteile parallel zueinander und in Richtung ihrer Schäfte übereinander angeordnet sind, wobei die Schäfte unterschiedliche Längen aufweisen. Durch die unterschiedlichen Längen der Schäfte ist es möglich, daß die Führungsösen aller Fadenführer auf einer gedachten Linie angeordnet werden können. Dennoch ist es möglich, daß einzelne Fadenführer in gewissen Grenzen individuell angesteuert werden können.Preferably, a plurality of yarn guides are provided, the holding parts are arranged parallel to each other and in the direction of their shafts one above the other, wherein the shafts have different lengths. Due to the different lengths of the shafts, it is possible that the guide eyelets of all yarn guides can be arranged on an imaginary line. Nevertheless, it is possible that individual thread guides can be controlled individually within certain limits.
Vorzugsweise verbreitern sich längere Schäfte an dem Ende, das mit dem Halteteil verbunden ist. Damit ist bei den längeren Fadenführern die gleiche Steifigkeit erzielbar wie bei den kürzeren Fadenführern. Die Verbreiterung kann zwar dazu führen, daß man bei der Befestigung der längeren Fadenführer an dem Zugelement mehr Platz benötigt. Dies ist jedoch unkritisch, weil man die Verbreiterungen, falls erforderlich, dreieckförmig über die Gruppe von Fadenführern hinausstehen lassen kann.Preferably, longer shanks widen at the end connected to the support member. This means that the same rigidity can be achieved with the longer thread guides as with the shorter thread guides. Although the broadening can lead to the need for more space in the attachment of the longer thread guide to the tension element. However, this is not critical, because one can leave the widenings, if necessary, triangular over the group of yarn guides.
Vorzugsweise ist das Halteteil in einer Nut in einem Barrenträger angeordnet. Die Nut, 'in der die Fadenführer mit sehr geringem Spiel gehalten sind, dient zusätzlich zur Stabilisierung bei der Bewegung der Fadenführer. Eine Bewegung ist im Grunde genommen nur parallel zur Erstreckung der Nut möglich. Dies ist eine weitere Maßnahme, um Momente aufzufangen, die über den Schaft auf das Halteteil ausgeübt werden könnten. Aufgrund der starren Verbindung zwischen dem Schaft und dem Halteteil, die beispielsweise durch Verschweißen oder Verlöten des Schaftes mit dem Halteteil oder durch eine einstückige Ausbildung dieser beiden Teile erreicht werden kann, wird erreicht, daß der Schaft mit der gleichen Kinematik bewegt wird, wie das Halteteil.Preferably, the holding part is arranged in a groove in a billet carrier. The groove, in which the yarn guides are held with very little play, additionally serves to stabilize the movement of the yarn guides. A movement is basically only possible parallel to the extension of the groove. This is another measure to catch moments that could be exerted on the shaft via the shaft. Due to the rigid connection between the shaft and the holding part, which can be achieved for example by welding or soldering the shaft to the holding part or by a one-piece design of these two parts, it is achieved that the shaft is moved with the same kinematics, as the holding part.
Vorzugsweise ist das Halteteil unter Zwischenlage von Gleitschuhen in der Nut geführt. Um die Gleiteigenschaften zu verbessern, ist es vorteilhaft, wenn der Fadenführer oder sein Halteteil keinen direkten Kontakt mit dem Flächen der Nut hat. Dieser Kontakt kann über die Gleitstücke hergestellt werden, die einen kleinen Abstand zwischen dem Halteteil und der Nut erzeugen und aus einem Werkstoff gebildet sein können, der mit dem Material des Barrenträgers möglichst reibungsarm zusammenwirkt. Gut geeignet hierzu sind in der Regel Kunststoffe. Die Gleitschuhe sind darüber hinaus als Verschleißteile ausgebildet, so daß man durch Auswechseln der Gleitschuhe eine hohe Lebensdauer der Fadenführer und der dazugehörigen Barre erreichen kann.Preferably, the holding part is guided with the interposition of sliding shoes in the groove. In order to improve the sliding properties, it is advantageous if the thread guide or its holding part has no direct contact with the surfaces of the groove. This contact can be made via the sliders, which produce a small distance between the holding part and the groove and can be formed from a material which interacts with the material of the billet carrier with as little friction as possible. Well suited to this are usually plastics. The shoes are also designed as wearing parts, so that you can achieve a long life of the thread guide and the associated barre by replacing the shoes.
Vorzugsweise sind die Gleitschuhe am Zugelement befestigt. Diese Ausbildung hat zwei Vorteile. Zum einen ergibt sich eine Abstützung des Halteteils in der Nut im größtmöglichen Abstand. Zum anderen wird auch verhindert, daß das Zugelement an den Wänden der Nut reibt.Preferably, the shoes are attached to the tension element. This training has two advantages. On the one hand results in a support of the holding part in the groove in the largest possible distance. On the other hand it is also prevented that the tension element rubs against the walls of the groove.
Günstig ist, wenn die Gleitschuhe U-förmig ausgebildet und auf das Zugelement aufgeklipst und/oder aufgeklebt sind. Die Positionierung der Gleitschuhe erfolgt dann, wie gesagt, dicht an den beiden Enden des Halteteils. Das Aufklipsen ist eine Verbindung, die schnell gelöst werden kann. Eine zusätzliche Stabilisierung kann sich aber durch eine dauerhafte Verbindung, wie Kleben, ergeben.It is advantageous if the sliding shoes are U-shaped and clipped onto the tension element and / or glued. The positioning of the shoes is then, as I said, close to the two ends of the holding part. The clipping is a connection that solved quickly can be. However, additional stabilization can result from a permanent bond such as sticking.
Bevorzugterweise weist der Barrenträger eine Abdeckung auf. Die Abdeckung deckt die Nut ab und darüber hinaus einen Bereich, in dem sich der Schaft der Fadenführer erstreckt. Die Abdeckung führt also zu einer Erhöhung der Querstabilität. Die Abdeckung kann aus Gleitmaterial bestehen oder mit solchem beschichtet sein.Preferably, the billet carrier on a cover. The cover covers the groove and beyond an area in which the shaft of the thread guide extends. The cover thus leads to an increase in the transverse stability. The cover may be made of or coated with sliding material.
Hierbei ist besonders bevorzugt, daß zwei Barrenträger unter Zwischenlage der Abdeckung mit ihren die Nut aufweisenden Seiten aneinander anliegen. Hier reicht dann eine relativ dünne Zwischenplatte mit guter Gleiteigenschaft aus, weil sich die Fadenführer gegenseitig abstützen, also in ihrer Bewegung nicht nur nicht behindern, sondern die Querstabilität sogar erhöhen.In this case, it is particularly preferred that two bar carriers abut each other with the interposition of the cover with their sides having the groove. Here then a relatively thin intermediate plate with good sliding property is sufficient because the thread guides support each other, so not only do not hinder their movement, but even increase the stability.
Vorzugsweise ist das Zugelement an mindestens einem Ende mit einem Gewinde versehen, das mit einem Antriebselement in Eingriff bringbar ist. Damit bei der Rapportverstellung neue Fadenführer zugeführt oder überflüssige abgenommen werden können, dürfen die Zugelemente, d.h. Drähte oder Seile, an ihren Enden keine Dickstellen oder Ösen aufweisen, die nicht mehr durch die Nut hindurchpassen. Man kann daher die Zugelemente mit Gewinden an mindestens einer Seite versehen. Das Gewinde ermöglicht eine feste und platzsparende Verbindung mit dem Antrieb des Zugelementes (oder mit einer entsprechenden Spanneinrichtung auf der anderen Seite). Es ermöglicht aber nach dem Entfernen des Antriebs oder der Spanneinrichtung, daß das Zugelement aus der Nut herausgezogen wird. Natürlich kann man anstelle eines Gewindes auch eine andere Befestigungsgeometrie verwenden, die ebenfalls nicht oder nicht wesentlich zu einer Vergrößerung der Querschnittsfläche des Zugelements beitragen. Denkbar ist beispielsweise eine Art Bajonettverschluß.Preferably, the tension member is provided at at least one end with a thread engageable with a drive member. So that during the repeat adjustment new thread guides supplied or unnecessary can be removed, the tension elements, ie wires or ropes, at their ends must not have thick points or eyes that no longer fit through the groove. It is therefore possible to provide the tension elements with threads on at least one side. The thread allows a solid and space-saving connection with the drive of the tension element (or with a corresponding clamping device on the other side). But it allows after removing the drive or the tensioning device that the tension element out of the groove is pulled out. Of course, you can also use a different mounting geometry instead of a thread, which also do not or not significantly contribute to an increase in the cross-sectional area of the tension member. It is conceivable, for example, a kind of bayonet lock.

Zum Antrieb der Fadenführer 4 sind Zugelemente 7 vorgesehen, die als Draht oder Drahtseil ausgebildet sind, also einen relativ kleinen Querschnitt aufweisen. Die Zugelemente 7 sind, was anhand der nachfolgenden
Das andere Ende des Zugelements 7 ist mit einem Spannband 11 verbunden, das über eine Umlenkrolle 12 geführt ist und ebenfalls in einem Spannelement 13 festgelegt ist. Das Spannelement 13, das ebenfalls als einfach wirkender Druckluftzylinder ausgebildet ist, wird von einer Druckquelle P1 mit Druckluft versorgt. Die Drücke der Druckquellen P, P1 und die wirksamen Druckangriffsflächen der Spannelemente 10, 13 sind so aufeinander abgestimmt, daß auf beide Ende des Zugelements 7 die gleiche Kraft ausgeübt wird. Der Antriebsmotor 9 muß daher lediglich Kräfte aufbringen, die zur Bewegung des Zugelements 7 erforderlich sind. Er muß jedoch keine Kräfte aufbringen, die zum Spannen einer Feder oder einer anderen Spanneinrichtung erforderlich sind.The other end of the
Der Fadenführer 4 weist einen Schaft 14 auf, an dessen unterem Ende eine Fadenführeröse 15 angeordnet ist, die sich in einer Lochnadel 16 befindet, die im Schaft 14 befestigt ist.The
Das obere Teil des Schaftes 14 ist mit einem Halteteil 17 fest verbunden, also verschweißt oder verlötet oder der Schaft 14 ist einstückig mit dem Halteteil 17 ausgebildet. Der Halteteil 17 weist eine Längsbohrung auf, durch die das Zugelement 7 geführt ist. Eine Klemmschraube 18 im Halteteil 17 dient dazu, das Halteteil 17 auf dem Zugelement 7 festzuklemmen. Wenn man die Klemmschraube 18 löst, kann man das Halteteil auf dem Zugelement 7 in Versatzrichtung 6 verschieben und an einer anderen Position durch Festziehen der Klemmschraube 18 wieder festlegen.The upper part of the
An den beiden Enden des Halteteils 17 sind Gleitschuhe 19, 20 angeordnet. Die Gleitschuhe 19, 20 haben einen U-förmigen Querschnitt. Sie sind auf das Zugelement 7 aufgeklipst und können gegebenenfalls dort mit einem Klebstoff festgelegt sein, wobei der Klebstoff hauptsächlich die Aufgabe hat, ein Fixieren der Gleitschuhe 19, 20 an den Enden des Halteteiles 17 im Betrieb zu bewirken. Wenn eine Verschiebung des Fadenführers 4 auf dem Zugelement 7 erforderlich ist, dann kann man durch einfaches Aufbiegen der Gleitschuhe 19, 20 ein Lösen der Gleitschuhe 19, 20 vom Zugelement 7 erreichen, so daß der Fadenführer 4 an eine neue Position verbracht werden kann.At the two ends of the holding

Da mehrere Nuten 21 parallel zueinander in dem Barrenträger 5 vorhanden sind, kann man auch eine entsprechend große Anzahl von Fadenführern 4 pro Gruppe 2, 3 unterbringen. Dargestellt sind acht Fadenführer 4. Versuche haben ergeben, daß man bei einer derartigen Barre bis zu zwölf Fadenführer pro Gruppe unterbringen kann.Since a plurality of
Die Seite des Barrenträgers 5, in die sich die Nuten 21 öffnen, ist von einer Abdeckung 22 abgedeckt. Die Abdeckung 22 ist dabei so weit in Richtung auf die Fadenführeröse 15 vorgezogen, daß sie auch einen relativ großen Teil des Schaftes 14 mit abdeckt. Die Abdeckung 22 kann beispielsweise mit Hilfe einer Schraube 23 am Barrenträger 5 befestigt sein, so daß die Abdeckung 22 abgenommen werden kann, wenn einzelne Fadenführer 4 gewartet, ausgetauscht, entfernt oder ergänzt werden sollen.The side of the
Die Abdeckung 22 kann aus Gleitmaterial, beispielsweise einem Kunststoff, bestehen oder mit einem solchen beschichtet sein. Im Fall der Einfachlegebarre nach
Damit man bei einer Rapportverstellung neue Fadenführer zuführen oder überflüssige abnehmen kann, dürfen die Zugelemente 7 an ihren Enden keine Dickstellen oder Ösen aufweisen. Die Zugelemente 7 sind daher an mindestens einem Ende mit einem Außengewinde 25 versehen, auf das eine Zugöse 26 aufgeschraubt werden kann, in die das Antriebsband 8 oder das Spannband 11 eingehängt werden kann.So that you can feed new thread guides or remove superfluous in a repeat adjustment, the
Um bei einem Fadenführer 4b mit einem längeren Schaft 14b die gleiche mechanische Stabilität zu erzielen wie bei einem Fadenführer 4a mit kürzerem Schaft 14a ist vorgesehen, daß sich bei den längeren Schäften 14b in Richtung auf das Halteteil 17b eine Verbreiterung 27 des Schaftes 14b ergibt.In order to achieve the same mechanical stability with a
Diese Verbreiterung 27 benötigt zwar in Versatzrichtung etwas mehr Bauraum. Dies ist aber unkritisch, weil die Verbreiterung 27 gegenüber dem Schaft 14b auch abgewinkelt sein kann, so daß die Verbreiterungen 27 insgesamt die Form eines Dreiecks aufweisen können.Although this widening 27 requires slightly more installation space in the offset direction. However, this is not critical, because the widening 27 may also be angled relative to the
Durch die Befestigung des Fadenführers 4 über das Halteteil 17 am Zugelement 7 und die Abstützung des Halteteils 7 sowohl am Zugelement 7 als auch über die Gleitschuhe 19, 20 in der Nut 21 wird eine sehr stabile Positionierung des Fadenführers 4 am Barrenträger 5 erreicht, d.h. Momente, die durch Kräfte im Bereich der Fadenführeröse 15 auf den Fadenführer 4 aufgebracht werden, werden durch die relativ große Breite des Halteteils 7 aufgenommen.By attaching the
Hierbei sind einige Dimensionierungen von Vorteil. So sollte die Länge des Schaftes H höchstens das Doppelte der Länge des Halteteils 17 betragen. Auch ist von Vorteil, wenn der Querschnitt des Schaftes 14 außerhalb der Verstärkung 27 kleiner ist als der Querschnitt des Halteteils 17.Here are some dimensions of advantage. Thus, the length of the shaft H should be at most twice the length of the holding
Als Antriebsband 8 und als Spannband 11 können Zahnriemen oder Flachriemen verwendet werden, die mit dem Antriebsmotor 9 oder der Umlenkrolle 12 einen guten Eingriff ermöglichen. Die Spannelemente 10, 13 können als Glasröhrchen mit Graphitkolben ausgebildet sein. Die Graphitkolben laufen in Glas zumindest annähernd verschleißfrei. Die Glaskolben blasen sich nicht auf und haben einen relativ kleinen Luftverlust. Mit einer Ausbildung der Spannelemente 10, 13 als einfach wirkende Druckluftzylinder läßt sich erreichen, daß die Vorspanneigenschaften nicht längenabhängig sind, wie dies beispielsweise dann der Fall wäre, wenn man als Spanneinrichtung eine Feder verwenden würde. Dementsprechend muß der Antriebsmotor 9 lediglich die Kraft aufbringen, die zum Antrieb der Fadenführer 4 erforderlich ist, nicht jedoch die Kraft, die zum Spannen einer Rückstelleinrichtung erforderlich wäre.As a drive belt 8 and as a clamping
Die zum Antrieb der Fadenführer verwendeten Elemente, nämlich das Zugelement 7, das Antriebsband 8, das Spannband 11 und die Gleitschuhe 19, 20 sind von relativ geringer Masse, so daß man mit der dargestellten Konstruktion relativ hohe Beschleunigungen und damit Betriebsfrequenzen erreichen kann.The elements used to drive the thread guide, namely the
Das Halteteil 117 weist nun eine in Versatzrichtung 6 verlaufende Nut 29 auf, die einseitig offen ist. Wie aus
Bei dieser Ausgestaltung ist eine Änderung der Position des Fadenführers am Zugelement 7 zwar nicht mehr ohne weiteres möglich. Für eine neue Position des Fadenführers am Zugelement wird man daher zweckmäßigerweise ein neues Zugelement verwenden. Die Herstellung ist jedoch außerordentlich einfach. Auch weist ein derartiger Fadenführer in der Regel nur ein geringeres Gewicht auf.In this embodiment, a change in the position of the thread guide on the
