Definitions
- the invention relates to a shaft rod for a heald frame according to the preamble of claim 1.
- heald frames made of light metal hollow profiles have been used for heald frames, each consisting of two shaft rods connected to one another by side supports, in which the heddle support rail is integrally formed in each case.
- the weaving machines are supposed to run at ever higher numbers of revolutions and wider and wider weaving machines are being built, the load capacity of the rapidly oscillating heald frames, whose shaft rods made of light metal profiles do not have sufficient flexural strength, is reached. Since the alternating bending strength of steel is significantly better than that of light metal, shaft rods made of steel have also been proposed for wide heald frames in high-speed weaving machines.
- These shaft rods which are designed as a sandwich construction, have very thin-walled sheet metal parts on the broad sides and thicker longitudinal profiles on the narrow sides of a supporting rod which forms a hollow body and which also carries the parallel extending stranded support rail on a metallic connecting part in order to reduce the weight.
- Such a shaft rod known from DE-A-37 02 524 consists of a plurality of, in particular, flat and non-deformed individual parts, which have a corresponding number Weld seams are joined together to form a shaft rod.
- this construction has several disadvantages. Not only are there too many weld seams required, which increases the cost of production, the necessary precision with regard to the straightness of the shaft rod to be produced being difficult to achieve due to the large number of weld seams, but the material thickness of the thicker sheet metal parts forming the narrow sides of the support rod is also not sufficient, to ensure a high bending strength of the construction. Because of the vibrations that occur during operation of the heald frame in the weaving machine, the shaft rod creates sound waves, but the sound-absorbing effect of the foam body contained in the cavity of the support rod is only very slight.
- the object of the present invention was therefore to provide a heald frame for a heald frame which can be produced more cost-effectively and which can also be easily adapted to the individual requirements of the customer in terms of stiffness and weight of the heald frame with simple measures, and which also is much better soundproofed due to its structure.
- the shaft rod has the features according to the patent claims. All metallic parts of the shaft rod are preferably connected to one another by means of laser welding. A high bending strength is achieved with the solid longitudinal bar, which is essentially rectangular in cross-section, on one narrow side of the supporting bar, an advantage of this construction being that the cross-section of this longitudinal bar can be made smaller or larger as required to achieve changes in properties.
- the gauges and auxiliary tools used in the manufacture do not have to be changed in order to produce shaft rods with different properties. It is also possible to have a cross-sectional profile of the longitudinal rod that increases in size towards the longitudinal center in order to produce a significantly stiffer shaft rod without changing its external dimensions.
- the shaft rod shown in Fig. 1 for a heald frame has a support rod 1 designed as a hollow body and then downwards a support part 2, which consists of a multi-angled profile rail and to which the heddle support rail 3 extending parallel to the support rod 1 is fastened.
- the support rod 1 is of a solid cross-section substantially rectangular longitudinal rod 4, which forms one narrow side, and of the parallel extending and the other narrow side forming leg 5 of the multi-angled support part 2 and two thin-walled and over the entire length of Shaft rod extending sheet metal parts 6 and 7 are formed, which are welded to the longitudinal rod 4 and on the carrier part 2 outside.
- the connection is preferably made by means of laser welding.
- the shaft rod is finished with a total of five weld seams.
- the four weld seams on the support rod 1 lie opposite one another in pairs, so that due to this symmetry the warping that otherwise occurs during welding can be avoided, so that a high precision with regard to the straightness of the shaft rod can be achieved. Since the heddle support rail 3 is welded on from its rear, the front remains completely smooth, so that the healds, not shown, can slide freely on the heddle support rail.
- the depth of the bead 9 can be made with different dimensions during manufacture, so that even a welded-on, thinner stranded support rail is in the right place and this way a further weight reduction can be achieved if this involves a certain loss in rigidity is desired.
- the support rod 1 encloses a cavity which is filled with a filler 10. 1 has a honeycomb-shaped structure with a large number of individual cavities 11 which extend transversely therethrough.
- Each of these individual cavities 11 is filled with an elastic, sound-absorbing material.
- This is a soft foam that has good adhesive properties.
- the filler body 10 with the honeycomb structure now has only a very small area on the end faces facing the sheet metal parts 6 and 7, which is suitable for the adhesive connection with the sheet metal parts. Since the sheet metal parts 6 and 7 are only 0.15 mm to 0.25 mm thick, buckling of the thin sheet metal parts must be prevented by additional measures because of the low supporting effect of the honeycomb-shaped filler.
- a material strip 12 is arranged on both sides of the packing 10, which is impregnated with an adhesive, which can only be activated for the gluing process and only then hardens.
- the material strip consists of fabric or non-woven fabric and is commercially available soaked with adhesive under the name "Prepreg".
- the double-sided adhesive material strips 12 have the effect that the very thin-walled sheet metal parts 6 and 7 are connected over the entire surface to the filler body 10 in order to prevent the buckling of these sheet metal parts, which is crucial for the stability of the entire shaft rod.
- a material can be selected for the material strip 12 which retains high elasticity even after the adhesive layer has hardened. It is achieved that the thin sheet metal parts 6 and 7 do not bulge, but are still well soundproofed.
- the filling body 10 can also be a rigid foam 13 with a large number of holes 14 extending transversely therethrough. These individual cavities 14 are then also filled with a sound-absorbing material that remains elastic.
- the described shaft rod has the particular advantages that it can be modified by constructively changing its individual components, such as the cross section of the longitudinal rod 4 or the sheet thickness of the support part 2 for the heddle support rail 3 or the depth of the bead 9 for fastening the heddle support rail and the cross section of this heddle support rail and the selection of the material for the filler body 10 can be adapted to the specific needs of the weaving company with the outer dimensions of the shaft rod unchanged.
- a shaft rod with high rigidity can be produced for very heavy fabrics or for very wide fabrics, which, thanks to the high rigidity, can be used without the frequently disturbing intermediate strut.
- a shaft rod with a relatively low weight can be produced. It is particularly advantageous that modified shaft rods can be produced in the individual components using the same production means, which allows economical production.
Description
Die Erfindung betrifft einen Schaftstab für einen Webschaft gemäss Oberbegriff des Anspruchs 1.The invention relates to a shaft rod for a heald frame according to the preamble of claim 1.
Bisher wurden für Webschäfte, die jeweils aus zwei durch Seitenstützen miteinander verbundenen Schaftstäben bestehen, aus Leichtmetall-Hohlprofilen bestehende Schaftstäbe verwendet, bei denen die Litzentragschiene jeweils einstückig angeformt ist. Weil aber die Webmaschinen heute mit immer höheren Tourenzahlen laufen sollen und auch immer breitere Webmaschinen gebaut werden, gelangt man an Grenzen der Belastbarkeit der sehr schnell oszillierend bewegten Webschäfte, deren aus Leichmetallprofilen bestehende Schaftstäbe keine ausreichende Wechselbiegefestigkeit besitzen. Da die Wechselbiegefestigkeit von Stahl wesentlich besser ist als jene von Leichmetall, sind insbesondere für breite Webschäfte in hochtourig laufenden Webmaschinen inzwischen auch wieder aus Stahl hergestellte Schaftstäbe vorgeschlagen worden. Diese als Sandwichkonstruktion ausgebildeten Schaftstäbe weisen zwecks Reduzierung des Gewichts sehr dünnwandige Blechteile an den Breitseiten und dickere Längsprofile an den Schmalseiten eines einen Hohlkörper bildenden Tragstabs auf, der ferner an einem metallischen Verbindungsteil die sich parallel erstreckende Litzentragschiene trägt.So far, heald frames made of light metal hollow profiles have been used for heald frames, each consisting of two shaft rods connected to one another by side supports, in which the heddle support rail is integrally formed in each case. However, because the weaving machines are supposed to run at ever higher numbers of revolutions and wider and wider weaving machines are being built, the load capacity of the rapidly oscillating heald frames, whose shaft rods made of light metal profiles do not have sufficient flexural strength, is reached. Since the alternating bending strength of steel is significantly better than that of light metal, shaft rods made of steel have also been proposed for wide heald frames in high-speed weaving machines. These shaft rods, which are designed as a sandwich construction, have very thin-walled sheet metal parts on the broad sides and thicker longitudinal profiles on the narrow sides of a supporting rod which forms a hollow body and which also carries the parallel extending stranded support rail on a metallic connecting part in order to reduce the weight.
Ein solcher aus der DE-A-37 02 524 bekannter Schaftstab besteht aus einer Mehrzahl insbesondere flachen und nicht verformten Einzelteilen, die durch entsprechend viele Schweissnähte zu einem Schaftstab zusammengefügt sind. Diese Konstruktion weist jedoch verschiedene Nachteile auf. Es sind nicht nur zuviele Schweissnähte erforderlich, was die Herstellung verteuert, wobei die nötige Präzision bezüglich der Geradheit des herzustellenden Schaftstabs wegen der vielen Schweissnähte nur schwer zu erreichen ist, sondern es reicht auch die Materialstärke der die Schmalseiten des Tragstabs bildenden dickeren Blechteile nicht aus, um eine hohe Biegefestigkeit der Konstruktion zu gewährleisten. Wegen der auftretenden Schwingungen beim Betrieb des Webschaftes in der Webmaschine lässt der Schaftstab Schallwellen entstehen, doch ist die schalldämpfende Wirkung des in dem Hohlraum des Tragstabs enthaltenen Schaumkörpers nur sehr gering.Such a shaft rod known from DE-A-37 02 524 consists of a plurality of, in particular, flat and non-deformed individual parts, which have a corresponding number Weld seams are joined together to form a shaft rod. However, this construction has several disadvantages. Not only are there too many weld seams required, which increases the cost of production, the necessary precision with regard to the straightness of the shaft rod to be produced being difficult to achieve due to the large number of weld seams, but the material thickness of the thicker sheet metal parts forming the narrow sides of the support rod is also not sufficient, to ensure a high bending strength of the construction. Because of the vibrations that occur during operation of the heald frame in the weaving machine, the shaft rod creates sound waves, but the sound-absorbing effect of the foam body contained in the cavity of the support rod is only very slight.
Die Aufgabe der vorliegenden Erfindung bestand daher darin, einen Schaftstab für einen Webschaft zu schaffen, der kostengünstiger herstellbar ist und der sich bei der Herstellung auch den individuellen Anforderungen des Kunden in bezug auf Steifigkeit und Gewicht des Schaftstabs leicht mit einfachen Massnahmen anpassen lässt und der ferner aufgrund seines Aufbaus wesentlich besser schallgedämpft ist.The object of the present invention was therefore to provide a heald frame for a heald frame which can be produced more cost-effectively and which can also be easily adapted to the individual requirements of the customer in terms of stiffness and weight of the heald frame with simple measures, and which also is much better soundproofed due to its structure.
Zur Lösung dieser Aufgabe weist der Schaftstab die Merkmale gemäss den Patentansprüchen auf. In bevorzugter Weise sind alle metallischen Teile des Schaftstabs mittels Laserschweissung miteinander verbunden. Mit dem massiven, im Querschnitt im wesentlichen rechteckförmigen Längsstab an der einen Schmalseite des Tragstabs erzielt man eine hohe Biegefestigkeit, wobei ein Vorteil dieser Konstruktion darin besteht, dass man je nach Bedarf den Querschnitt dieses Längsstabs kleiner oder grösser wählen kann, um dadurch Änderungen der Eigenschaften zu erzielen. Die für die Herstellung verwendeten Lehren und Hilfswerkzeuge müssen nicht geändert werden, um Schaftstäbe mit verschiedenen Eigenschaften herzustellen. Auch ein gegen die Längsmitte grösser werdendes Querschnittsprofil des Längsstabs ist möglich, um einen wesentlich steiferen Schaftstab herzustellen, ohne dass sich dessen Aussenmasse dabei ändern.To achieve this object, the shaft rod has the features according to the patent claims. All metallic parts of the shaft rod are preferably connected to one another by means of laser welding. A high bending strength is achieved with the solid longitudinal bar, which is essentially rectangular in cross-section, on one narrow side of the supporting bar, an advantage of this construction being that the cross-section of this longitudinal bar can be made smaller or larger as required to achieve changes in properties. The gauges and auxiliary tools used in the manufacture do not have to be changed in order to produce shaft rods with different properties. It is also possible to have a cross-sectional profile of the longitudinal rod that increases in size towards the longitudinal center in order to produce a significantly stiffer shaft rod without changing its external dimensions.
Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:
- Fig. 1 in schaubildlicher Darstellung einen Vertikalschnitt durch den Schaftstab, teilweise aufgebrochen dargestellt;
- Fig. 2 eine abgewandelte Ausführungsform des Schaftstabs.
- Figure 1 is a perspective view of a vertical section through the shaft rod, partially broken open.
- Fig. 2 shows a modified embodiment of the shaft rod.
Der in Fig. 1 dargestellte Schaftstab für einen Webschaft weist einen als Hohlkörper ausgebildeten Tragstab 1 auf sowie nach unten anschliessend einen Trägerteil 2, der aus einer mehrfach abgewinkelten Profilschiene besteht und an welchem die parallel zum Tragstab 1 sich erstreckende Litzentragschiene 3 befestigt ist. Der Tragstab 1 ist von einem massiven im Querschnitt im wesentlichen rechteckförmigen Längsstab 4, der die eine Schmalseite bildet, und von dem sich dazu parallel erstreckenden und die andere Schmalseite bildenden Schenkel 5 des mehrfach abgewinkelten Trägerteils 2 sowie von zwei dünnwandigen und über die ganze Länge des Schaftstabs sich erstreckenden Blechteilen 6 und 7 gebildet, die an dem Längsstab 4 und an dem Trägerteil 2 aussen angeschweisst sind. Die Verbindung erfolgt vorzugsweise mittels Laserschweissung.The shaft rod shown in Fig. 1 for a heald frame has a support rod 1 designed as a hollow body and then downwards a support part 2, which consists of a multi-angled profile rail and to which the
Der einstückig ausgebildete und aus Blech mit einer Wandstärke von 0,7 mm bis 1,25 mm bestehende Trägerteil 2, dessen einer Schenkel 5 mit den Blechteilen 6 und 7 verschweisst ist, weist an seinem anderen Schenkel 8 im Abstand vom unteren Rand eine längs verlaufende Sicke 9 auf. An dieser ist aussenseitig die einstückig ausgebildete und vorzugsweise aus gehärtetem Stahl bestehende Litzentragschiene 3 von der Innenseite der Sicke 9 aus angeschweisst. Mit insgesamt fünf Schweissnähten ist der Schaftstab fertig hergestellt. Die vier Schweissnähte am Tragstab 1 liegen paarweise einander gegenüber, sodass aufgrund dieser Symmetrie der beim Schweissen sonst auftretende Verzug vermieden werden kann, sodass eine hohe Präzision in bezug auf die Geradheit des Schaftstabs erreichbar ist. Da die Litzentragschiene 3 von ihrer Rückseite aus angeschweisst ist, bleibt die Vorderseite vollkommen glatt, sodass die nicht dargestellten Weblitzen auf der Litzentragschiene frei gleiten können.The integrally formed and made of sheet metal with a wall thickness of 0.7 mm to 1.25 mm, the support part 2, one leg 5 is welded to the sheet metal parts 6 and 7, has on its other leg 8 at a distance from the lower edge of a longitudinal Bead 9. The one-piece
Die Tiefe der Sicke 9 kann bei der Herstellung je nach Bedarf mit unterschiedlichem Mass hergestellt werden, sodass auch eine angeschweisste dünnere Litzentragschiene sich an der richtigen Stelle befindet und man auf diese Weise eine weitere Gewichtsreduktion erzielen kann, falls dies bei Inkaufnahme einer gewissen Einbusse an Steifigkeit gewünscht ist.The depth of the bead 9 can be made with different dimensions during manufacture, so that even a welded-on, thinner stranded support rail is in the right place and this way a further weight reduction can be achieved if this involves a certain loss in rigidity is desired.
Der Tragstab 1 umschliesst einen Hohlraum, der mit einem Füllkörper 10 ausgefüllt ist. Dieser hat gemäss Fig. 1 eine bienenwabenförmige Struktur mit einer Vielzahl von Einzelhohlräumen 11, die sich quer hindurch erstrecken.The support rod 1 encloses a cavity which is filled with a
Jeder dieser Einzelhohlräume 11 ist mit einem elastisch bleibenden, schalldämmenden Material gefüllt. Hierbei handelt es sich um einen Weichschaum, welcher gute Klebeeigenschaften aufweist. Der Füllkörper 10 mit der bienenwabenförmigen Struktur weist nun an den den Blechteilen 6 und 7 zugekehrten Endflächen nur eine sehr kleine, für die Klebverbindung mit den Blechteilen geeignete, Fläche auf. Da die Blechteile 6 und 7 nur 0,15 mm bis 0,25 mm dick sind, muss wegen der geringen Stützwirkung des bienenwabenförmigen Füllkörpers das Beulen der dünnen Blechteile mit zusätzlichen Massnahmen verhindert werden. Zu diesem Zweck ist auf beiden Seiten des Füllkörpers 10 je ein Materialstreifen 12 angeordnet, welcher mit einem Kleber getränkt ist, welcher erst für den Klebevorgang aktiviert werden kann und dann erst aushärtet. Der Materialstreifen besteht aus Gewebe oder Faservlies und ist mit Kleber getränkt unter der Bezeichnung "Prepreg" im Handel erhältlich. Die beidseitig klebenden Materialstreifen 12 bewirken, dass die sehr dünnwandigen Blechteile 6 und 7 über die ganze Fläche mit dem Füllkörper 10 verbunden sind, um das Beulen dieser Blechteile zu verhindern, was für die Stabilität des ganzen Schaftstabes ausschlaggebend ist. Für den Materialstreifen 12 kann ein Material gewählt werden, welches auch nach dem Aushärten der Klebeschicht eine hohe Elastizität behält. Man erreicht damit, dass die dünnen Blechteile 6 und 7 nicht ausbeulen, aber trotzdem gut schallgedämpft sind.Each of these individual cavities 11 is filled with an elastic, sound-absorbing material. This is a soft foam that has good adhesive properties. The
Der Füllkörper 10 kann anstelle der bienenwabenförmigen Struktur gemäss Fig. 2 auch ein Hartschaum 13 mit einer Vielzahl sich quer hindurch erstreckender Löcher 14 sein. Diese Einzelhohlräume 14 sind dann ebenfalls mit einem elastisch bleibenden schalldämmenden Material gefüllt.Instead of the honeycomb-shaped structure according to FIG. 2, the filling
Mit dieser aus fünf Schichten bestehenden Sandwichkonstruktion, die die beiden äusseren Blechteile 6 und 7, die Materialstreifen 12 und den Füllkörper 10 umfasst, sind sehr gute Ergebnisse bezüglich der Festigkeit des Schaftstabes erzielt worden. Der beschriebene Schaftstab besitzt insbesondere die Vorteile, dass er durch konstruktives Verändern seiner einzelnen Bestandteile, wie beispielsweise des Querschnitts des Längsstabs 4 oder der Blechdicke des Trägerteils 2 für die Litzentragschiene 3 oder der Tiefe der Sicke 9 für die Befestigung der Litzentragschiene sowie des Querschnitts dieser Litzentragschiene und der Auswahl des Materials für den Füllkörper 10 bei unveränderten Aussenabmessungen des Schaftstabs in weiten Bereichen den spezifischen Bedürfnissen des Webereibetriebes angepasst werden kann. Auf diese Weise lässt sich beispielsweise für sehr schwere Gewebe oder für sehr breite Gewebe ein Schaftstab mit hoher Steifigkeit herstellen, mit dem dank der hohen Steifigkeit ohne die häufig störende Zwischenstrebe gearbeitet werden kann. Für sehr schnell laufende Webmaschinen kann andererseits ein Schaftstab mit relativ geringem Gewicht hergestellt werden. Dabei ist von besonderem Vorteil, dass in den einzelnen Bestandteilen abgeänderte Schaftstäbe mit den gleichen Fertigungsmitteln hergestellt werden können, was eine kostengünstige Produktion erlaubt.With this sandwich construction consisting of five layers, which comprises the two outer sheet metal parts 6 and 7, the
