Definitions
- Shaft rods for heald frames are known in many designs.
- hollow profile rods extruded from aluminum are often used as the base body for the shaft rod.
- Additional components such as a stranded support rail, guide elements, drive elements, components for connecting a side support and others are usually attached to these aluminum profiles.
- stiffening rods e.g. carbon fiber composite rods and damping strips made of plastic, are known as stops for the strands lined up with play.
- the DE 102 06 130 B4 shows a damping band that is firmly clamped to an aluminum shaft rod or to an additional intermediate profile. There is no stiffening bar.
- the DE 199 62 977 A1 shows damping tapes that are glued on, for example. No stiffening bar is shown in this document.
- the EP 2 669 413 A1 shows a heald frame for high-speed looms which has both a stiffening rod and a damping band.
- the damping band is placed in or around the stiffening rod and held by it with little play by a kind of form fit.
- the in EP 2 669 413 A1 The stiffening rods and / or damping strips shown are very filigree and cannot be produced in a reproducible manner, or cannot be produced sufficiently, with the usual methods due to the small dimensions and narrow radii. In practice, these problems lead, among other things, to failure of the stiffening rod or the damping band. Due to the limited space, no way was found to fix the two partners with a form fit without at least one of the two being at risk of breakage.
- the object of the present invention is to propose a shaft rod in which a stiffening rod and a damping band are integrated into the installation space present on the shaft rod and in which the stiffening rod and the damping band also have sufficient stability.
- a shaft rod for high-speed looms has a base body and a stiffening rod.
- the shaft rod is characterized in that the base body, together with the stiffening rod, forms a receiving space in which a fastening element of a damping band can be held in a form fit as a stop for strands lined up with play.
- An appropriately adapted damping band can be added later or, if necessary, exchanged and replaced with a new one.
- a shaft rod which has a base body, a stiffening rod and a damping band and in which the main body together with the stiffening rod forms a receiving space in which a fastening element of the damping band is accommodated.
- the existing installation space can be used to the best possible extent by means of a receiving space which is delimited together by the base body and the reinforcing rod.
- a stiffening rod in the sense of the present invention applies to bodies fixed on a base body, the primary task of which is to increase the flexural rigidity of the base body.
- the heddle support rail also often noticeably increases the flexural rigidity of the base body, although the main task of the heddle support rail is to hold the strands.
- the stranded support rails are usually made of hardened steel.
- Fastening elements for the heddle support rail are also known from the prior art, which in turn can increase the flexural rigidity of the base body as a side effect. Such elements are also not a stiffening rod in the sense of this invention and are accordingly also formed from materials that differ from the material of the stiffening rod.
- the base body is preferably a hollow profile rod extruded from aluminum or a light metal alloy, which includes various functions.
- the heddle support rail can be attached to a chamberless extension of the base body.
- In the chamber there can be a Be housed connection to a side support. All elements that serve to fulfill such basic functionalities form the basic body - even in the case of a multi-part design.
- a base body which is set up for a shaft rod according to the invention provides the possibility of connecting a stiffening rod increasing its flexural rigidity and, with such a stiffening rod, forms a receiving space for a damping band.
- the stiffening rod is geometrically designed so that it can be easily attached to the base body in a way that is most advantageous for increasing the flexural strength of the base body and, for example, in the EP 2 669 413 A1 is described.
- the stiffening bar has geometric features with the aid of which a receiving space for a damping band is formed, for example a projection as explained in detail later.
- the reinforcing rod also fulfills the function of forming, together with the base body, a receiving space for a damping band.
- the stiffening bar should preferably not serve to fasten the heddle support rail to the base body.
- the damping band is preferably an extruded plastic profile.
- the base body, the stiffening body and preferably also the damping band run over the entire length of the shaft rod.
- the construction space available for the heald frame is limited in the transverse direction by the pitch of the heald frames in the loom, generally to 12 mm per heald frame.
- the main body of the shaft rod therefore usually has a maximum extension of approximately 10 mm or less in this direction.
- the optimal use of the installation space creates a receiving space in which a fastening element of a damping band fits, which can be produced in a stable and reproducible manner.
- the stiffening profile can be made less filigree than in the prior art and is accordingly also sufficiently stable.
- the fastening means is held in the receiving space by a form fit. This means that no additional elements are required to attach the damping profile to the shaft rod.
- the fastening element is advantageously received in the receiving space with play.
- the damping band can simply be drawn into the receiving space from the side in the longitudinal direction.
- the receiving space has an opening through which the fastening element of the damping band can engage in the receiving space. It is also preferred if a clear width of this opening is smaller than the clear width inside the receiving space, wherein according to the invention the slight width of the opening and the clear width of the receiving space are each delimited by the base body on the one hand and the stiffening rod on the other.
- An undercut can thus be formed for the fastening element.
- An undercut is generally a design feature that prevents separation from a second part by means of a protrusion or a widening on one part by the second part enclosing an open chamber or accessible space from which the protrusion or the widening of the first part cannot be destroyed without destruction or deformation can be taken out.
- the fastening element can then work together with the undercut and thus fix the damping band on the shaft rod.
- the fastening element can be angled while approximately maintaining its wall thickness.
- the fastening element widens compared to its simple wall thickness and cannot fall out of the receiving space because the fastening element is wider than the clear width of the opening of the receiving space due to this angled course.
- the undercut can be formed by the design of the stiffening rod or by the shape of the base body or by both.
- a projection can be arranged on the base body through which the clear width of the opening in the Compared to the clear width of the recording room is reduced.
- such a projection will project at least partially in the transverse direction against the course of the base body in the height direction.
- a projection running in this way can also or only be present on the stiffening rod.
- the receiving space can have at least one delimiting surface which is arranged at an acute angle to the vertical direction and to the transverse direction of the base body.
- the boundary surface of the receiving space arranged on the base body can only run in the height direction.
- the base body can be designed to be as weight-saving as possible.
- Figure 1 shows an embodiment of a shaft rod 1 in a sectional view parallel to the longitudinal direction L.
- no components that are insignificant for the invention such as guide elements and the like, are shown.
- Only a heddle support rail is shown.
- Only one gluing gap is shown at the gluing points; further simplifications that do not work directly with the invention have been implemented.
- a stiffening rod 3 and a damping band 4 are attached to the base body 2 in the vicinity of the heddle support rail.
- FIG 2 shows an enlarged section Figure 1 , in particular the stiffening rod 3 and the damping band 4 are clearly visible in this view.
- the stiffening rod 3 is encompassed by the base body 2 on parts of its extension from 3 sides.
- the stiffening rod 3 has a projection in the transverse direction at its lower end.
- the damping band 4 has a hollow body section and, proceeding therefrom, a fastening element 6 which is roughly in the form of the number “7”. As a result, the fastening element 6 expands in the transverse direction Q and is thus held in the receiving space 5 by a form fit.
- the projection of the stiffening rod 3 runs at an acute angle to the height direction H and to the transverse direction Q.
- the fastening element 6 of the damping band 4 rests on the corresponding inclined surface and on the boundary wall that is formed by the base body 2 and extends in the height direction H. It can be clearly seen that in this view there is still a free space in the receiving space 5 above the fastening element 6. The fastening element 6 is thus received in the receiving space 5 with play. It can also be clearly seen that the fastening element 6 is held in the receiving space 5 by a form fit and cannot fall out of the receiving space 5 in this illustration. Because of its curved shape, the fastening element 6 is wider than the clear width Wö of the opening 7 of the receiving space 5.
- the opening 7 of the receiving space 5 and the clear width Wö of the opening 7 and the clear width Wa in the interior of the receiving space 5 can be seen better in FIG.
- the Figure 3 the cutout Figure 2 , in which the damping band 4 is shifted in the height direction H downwards.
- the clear width Wö of the opening 7 and the clear width Wa inside the Recording space 5 are indicated by arrows. It can be clearly seen that the arrow for the clear width Wa in the interior of the receiving space 5 is longer than the arrow for the clear width Wö of the opening 7. This creates an undercut through the projection of the stiffening rod and the base body, whereby the damping band 4 by means of its Fastening element 6 can be set.
- Figure 4 shows a further embodiment of a shaft rod 1 in a view like Figure 1 .
- all of the boundary walls of the receiving space 5 run in the height direction H or transverse direction Q.
- the damping band again has a hollow body section, the fastening element runs at an angle of 90 °.
- the angled section of the fastening element 6 is held in the receiving space 5 by a form fit.

Description
Schaftstäbe für Webschäfte sind in vielen Ausführungen bekannt. Häufig werden heutzutage aus Aluminium stranggepresste Hohlprofilstäbe als Grundkörper für den Schaftstab verwendet. An diese Aluminiumprofile werden zumeist noch zusätzliche Bauteile wie eine Litzentragschiene, Führungselemente, Antriebselemente, Bauteile zur Anbindung einer Seitenstütze und weitere angebracht. Bei Schaftstäben für besonders schnell laufende Webmaschinen sind auch Versteifungsstäbe z.B. Kohlefaserverbundstäbe und Dämpfungsbänder aus Kunststoff als Anschlag für die mit Spiel aufgereihten Litzen bekannt.Shaft rods for heald frames are known in many designs. Nowadays, hollow profile rods extruded from aluminum are often used as the base body for the shaft rod. Additional components such as a stranded support rail, guide elements, drive elements, components for connecting a side support and others are usually attached to these aluminum profiles. In the case of shaft rods for particularly fast-running weaving machines, stiffening rods, e.g. carbon fiber composite rods and damping strips made of plastic, are known as stops for the strands lined up with play.

Es ist die Aufgabe der vorliegenden Erfindung einen Schaftstab vorzuschlagen, bei dem ein Versteifungsstab und ein Dämpfungsband in den am Schaftstab vorhandenen Bauraum integriert sind und bei dem außerdem der Versteifungsstab und das Dämpfungsband ausreichende Stabilität aufweisen.The object of the present invention is to propose a shaft rod in which a stiffening rod and a damping band are integrated into the installation space present on the shaft rod and in which the stiffening rod and the damping band also have sufficient stability.
Ein Schaftstab für schnell laufende Webmaschinen weist einen Grundkörper und einen Versteifungsstab auf. Der Schaftstab ist dadurch gekennzeichnet, dass der Grundkörper zusammen mit dem Versteifungsstab einen Aufnahmeraum bildet, in dem ein Befestigungselement eines Dämpfungsbandes als Anschlag für mit Spiel aufgereihte Litzen in einem Formschluss haltbar ist. Ein entsprechend angepasstes Dämpfungsband kann nachträglich eingebracht oder bei Bedarf auch ausgetauscht und durch ein neues ersetzt werden.A shaft rod for high-speed looms has a base body and a stiffening rod. The shaft rod is characterized in that the base body, together with the stiffening rod, forms a receiving space in which a fastening element of a damping band can be held in a form fit as a stop for strands lined up with play. An appropriately adapted damping band can be added later or, if necessary, exchanged and replaced with a new one.
Gelöst wird die Aufgabe auch durch einen Schaftstab, der einen Grundkörper, einen Versteifungsstab und ein Dämpfungsband aufweist und bei dem der Grundkörper zusammen mit dem Versteifungsstab einen Aufnahmeraum bildet, in dem ein Befestigungselement des Dämpfungsbandes aufgenommen ist. Durch einen Aufnahmeraum, der von dem Grundkörper und von dem Versteifungsstab zusammen begrenzt ist, läßt sich der vorhandene Bauraum bestmöglich ausnutzen. Als Versteifungsstab im Sinne der vorliegenden Erfindung gelten an einem Grundkörper festgelegte Körper, deren vornehmliche Aufgabe es ist, die Biegesteifigkeit des Grundkörpers zu erhöhen. Auch die Litzentragschiene erhöht oft merklich die Biegesteifigkeit des Grundkörpers, allerdings ist die vornehmliche Aufgabe der Litzentragschiene die Litzen zu halten. Deshalb kommen für die Litzentragschiene nur sehr verschleißresistente Materialien in Frage, meistens sind die Litzentragschienen aus gehärtetem Stahl gefertigt. Aus dem Stand der Technik sind zum Beispiel auch Befestigungselemente für die Litzentragschiene bekannt, die wiederum als Nebeneffekt die Biegesteifigkeit des Grundkörpers erhöhen können. Auch solche Elemente sind kein Versteifungsstab im Sinne dieser Erfindung und sind entsprechend auch aus vom Material des Versteifungsstabes abweichenden Materialien gebildet.The object is also achieved by a shaft rod which has a base body, a stiffening rod and a damping band and in which the main body together with the stiffening rod forms a receiving space in which a fastening element of the damping band is accommodated. The existing installation space can be used to the best possible extent by means of a receiving space which is delimited together by the base body and the reinforcing rod. A stiffening rod in the sense of the present invention applies to bodies fixed on a base body, the primary task of which is to increase the flexural rigidity of the base body. The heddle support rail also often noticeably increases the flexural rigidity of the base body, although the main task of the heddle support rail is to hold the strands. For this reason, only very wear-resistant materials can be used for the stranded support rails; the stranded support rails are usually made of hardened steel. Fastening elements for the heddle support rail are also known from the prior art, which in turn can increase the flexural rigidity of the base body as a side effect. Such elements are also not a stiffening rod in the sense of this invention and are accordingly also formed from materials that differ from the material of the stiffening rod.
Bevorzugt ist der Grundkörper ein aus Aluminium bzw. einer Leichtmetalllegierung stranggepresster Hohlprofilstab, der verschiedene Funktionen einschließt. Zum Beispiel kann an einem kammerlosen Fortsatz des Grundkörpers die Litzentragschiene befestigt werden. In der Kammer kann an beiden Enden eine Verbindung zu einer Seitenstütze untergebracht sein. Alle Elemente, die zur Erfüllung solcher Grundfunktionalitäten dienen, bilden - auch bei mehrteiliger Ausführung - den Grundkörper. Ein Grundkörper, der für einen erfindungsgemäßen Schaftstab eingerichtet ist, stellt die Möglichkeit zur Anbindung eines seine Biegesteifigkeit erhöhenden Versteifungsstabes bereit und bildet mit einem solchen Versteifungsstab einen Aufnahmeraum für ein Dämpfungsband.The base body is preferably a hollow profile rod extruded from aluminum or a light metal alloy, which includes various functions. For example, the heddle support rail can be attached to a chamberless extension of the base body. In the chamber there can be a Be housed connection to a side support. All elements that serve to fulfill such basic functionalities form the basic body - even in the case of a multi-part design. A base body which is set up for a shaft rod according to the invention provides the possibility of connecting a stiffening rod increasing its flexural rigidity and, with such a stiffening rod, forms a receiving space for a damping band.
Insofern ist der Versteifungsstab geometrisch so ausgeführt, dass er einfach so an dem Grundkörper befestigt werden kann, wie es für die Erhöhung der Biegesteifigkeit des Grundkörpers am vorteilhaftesten und z.B. in der
Der für den Webschaft zur Verfügung stehende Bauraum ist in Querrichtung durch den Teilungsabstand der Webschäfte in der Webmaschine limitiert, in der Regel auf 12mm pro Webschaft. Der Grundkörper des Schaftstabs weist in dieser Richtung daher zumeist eine maximale Ausdehnung von ungefähr 10mm oder weniger auf. Durch das zumeist stranggepresste Hohlkammerprofil des Grundkörpers sind die Richtungen am Grundkörper und Schaftstab wie folgt definiert: Die Richtung, in der sich der durch eine Pressmatrize erzeugte konstante Querschnitt des Hohlkammerprofils erstreckt, ist die Längsrichtung. Senkrecht hierzu ist in Querrichtung das Profil in seiner Ausdehnung zumeist auf ca. 10mm maximal begrenzt und schließlich ist die zu beiden vorgenannten senkrechte die Höhenrichtung. Durch die optimale Ausnutzung des Bauraums entsteht ein Aufnahmeraum, in den ein Befestigungselement eines Dämpfungsbandes passt, welches stabil und reproduzierbar herstellbar ist. Außerdem kann das Versteifungsprofil weniger filigran als im Stand der Technik ausgeführt werden und ist demzufolge ebenfalls ausreichend stabil.The construction space available for the heald frame is limited in the transverse direction by the pitch of the heald frames in the loom, generally to 12 mm per heald frame. The main body of the shaft rod therefore usually has a maximum extension of approximately 10 mm or less in this direction. Due to the mostly extruded hollow chamber profile of the base body, the directions on the base body and shaft rod are defined as follows: The direction in which the constant cross section of the hollow chamber profile produced by a press die extends is the longitudinal direction. At right angles to this, in the transverse direction, the profile is mostly limited to a maximum of approx. 10 mm and finally the vertical direction to both of the aforementioned is the height direction. The optimal use of the installation space creates a receiving space in which a fastening element of a damping band fits, which can be produced in a stable and reproducible manner. In addition, the stiffening profile can be made less filigree than in the prior art and is accordingly also sufficiently stable.
Das Befestigungsmittel wird durch einen Formschluss im Aufnahmeraum gehalten. Somit sind keine zusätzlichen Elemente zur Befestigung des Dämpfungsprofils am Schaftstab nötig.The fastening means is held in the receiving space by a form fit. This means that no additional elements are required to attach the damping profile to the shaft rod.
Vorteilhafterweise ist das Befestigungselement mit Spiel im Aufnahmeraum aufgenommen. Somit kann das Dämpfungsband zum Beispiel einfach von der Seite in Längsrichtung in den Aufnahmeraum eingezogen werden.The fastening element is advantageously received in the receiving space with play. Thus, for example, the damping band can simply be drawn into the receiving space from the side in the longitudinal direction.
In einer vorteilhaften Ausführung weist der Aufnahmeraum eine Öffnung auf, durch die das Befestigungselement des Dämpfungsbandes in den Aufnahmeraum eingreifen kann. Weiterhin ist bevorzugt, wenn eine lichte Weite dieser Öffnung kleiner ist als die lichte Weite im Inneren des Aufnahmeraums, wobei erfindungsgemäß die leichte Weite der Öffnung und die lichte Weite des Aufnahemraums jeweils durch den Grundkörper einerseits und den Versteifungsstab andererseits eingegrenzt sind. So kann eine Hinterschneidung für das Befestigungselement gebildet werden. Eine Hinterschneidung ist allgemein ein Konstruktionsmerkmal, das über einen Vorsprung oder eine Verbreiterung an einem Teil die Trennung von einem zweiten Teil verhindert, indem das zweite Teil eine offene Kammer oder zugänglichen Raum umschließt, aus dem der Vorsprung oder die Verbreiterung des ersten Teils nicht ohne Zerstörung oder Verformung herausgenommen werden kann. Das Befestigungselement kann dann mit der Hinterschneidung zusammen wirken und somit das Dämpfungsband am Schaftstab festlegen. Zu diesem Zweck kann das Befestigungselement unter ungefährer Beibehaltung seiner Wandstärke abgewinkelt verlaufen. Durch die Abwinkelung verbreitert sich das Befestigungselement im Vergleich zu seiner einfachen Wandstärke und kann so nicht aus dem Aufnahmeraum herausfallen, weil das Befestigungselement durch diesen abgewinkelten Verlauf breiter ist als die lichte Weite der Öffnung des Aufnahmeraums. Die Hinterschneidung kann durch die Ausgestaltung des Versteifungsstabes oder durch die formmäßige Ausgestaltung des Grundkörpers oder durch beide gebildet sein. Zum Beispiel kann ein Vorsprung am Grundkörper angeordnet sein, durch den die lichte Weite der Öffnung im Vergleich zur lichten Weite des Aufnahmeraums reduziert wird. Ein solcher Vorsprung wird hierzu zumindest teilweise in Querrichtung gegen den Verlauf des Grundkörpers in Höhenrichtung vorspringen. Ähnlich kann ein dermaßen verlaufender Vorsprung auch oder nur am Versteifungsstab vorliegen.In an advantageous embodiment, the receiving space has an opening through which the fastening element of the damping band can engage in the receiving space. It is also preferred if a clear width of this opening is smaller than the clear width inside the receiving space, wherein according to the invention the slight width of the opening and the clear width of the receiving space are each delimited by the base body on the one hand and the stiffening rod on the other. An undercut can thus be formed for the fastening element. An undercut is generally a design feature that prevents separation from a second part by means of a protrusion or a widening on one part by the second part enclosing an open chamber or accessible space from which the protrusion or the widening of the first part cannot be destroyed without destruction or deformation can be taken out. The fastening element can then work together with the undercut and thus fix the damping band on the shaft rod. For this purpose, the fastening element can be angled while approximately maintaining its wall thickness. As a result of the angling, the fastening element widens compared to its simple wall thickness and cannot fall out of the receiving space because the fastening element is wider than the clear width of the opening of the receiving space due to this angled course. The undercut can be formed by the design of the stiffening rod or by the shape of the base body or by both. For example, a projection can be arranged on the base body through which the clear width of the opening in the Compared to the clear width of the recording room is reduced. For this purpose, such a projection will project at least partially in the transverse direction against the course of the base body in the height direction. Similarly, a projection running in this way can also or only be present on the stiffening rod.
Der Aufnahmeraum kann mindestens eine Begrenzungsfläche aufweisen, die in einem spitzen Winkel zur Höhenrichtung und zur Querrichtung des Grundkörpers angeordnet ist. Durch eine solche Begrenzungsfläche kann das Dämpfungsband eine bevorzugte Ausrichtung zum Schaftstab erhalten, selbst wenn das Befestigungsmittel mit Spiel im Aufnahmeraum aufgenommen ist.The receiving space can have at least one delimiting surface which is arranged at an acute angle to the vertical direction and to the transverse direction of the base body. By means of such a boundary surface, the damping band can be given a preferred alignment with respect to the shaft rod, even if the fastening means is accommodated in the receiving space with play.
Die am Grundkörper angeordnete Begrenzungsfläche des Aufnahmeraums kann nur in der Höhenrichtung verlaufen. Dadurch kann der Grundkörper maximal gewichtssparend ausgelegt werden.The boundary surface of the receiving space arranged on the base body can only run in the height direction. As a result, the base body can be designed to be as weight-saving as possible.
Der Versteifungsstab kann aus Material mit höherer Biegesteifigkeit als Aluminium oder dessen Legierungen gebildet sein, vorzugsweise wird in einer Matrix gebundenes Fasermaterial, besonders bevorzugt Kohlefasern verwendet. Jegliches Material, das bei vorzugsweise geringerer Dichte eine höhere Biegesteifigkeit als der Grundkörper aufweist und fest mit dem Grundkörper verbunden, z.B. verklebt werden kann, kann vorteilhaft eingesetzt werden. Insbesondere ist der Versteifungsstab kein Zwischenprofil, das nur zum Befestigen der Dämpfung dient aber den vorgenannten Anforderungen an eine Versteifung nicht genügt. Bei diesen Anforderungen ist auch die Art und Weise der Verbindung an den Grundkörper wichtig. Bei den bevorzugten Ausführungsbeispielen kann eine großflächige, mindestens zweiseitige Verklebung in einer Kammer des Grundkörpers vorliegen.
