Abstract

A releasable corner fixing for a weaving beam consists of a pin-shaped projection (2a) on the side support (1) which is secured to the rod (4) of the weaving beam which takes the form of a hollow section by a setscrew (5). The clamped projection (2a) has a flat body (7a) formed in one piece with the side support (1) which forms a frame within which flexible vibration dampers (9a) lying against the frame are supported against a metal disc component (8a) passing through the frame which is riveted to a sheet-metal casing (10a) surrounding the outside of the frame (7a) with some clearance. Into the top of the U-shaped sheet metal casing (10a) is riveted a strip (12) against which the setscrew (5) is pressed. The side support (1) is thus connected to the rod (4) only via the vibration dampers (9a), vibrations between them are damped and the breakage of material prevented especially in fast machine running modes.

Description

Die Erfindung betrifft einen Webschaft mit lösbaren Eckverbindungen zwischen den Seitenstützen und den aus Hohlprofilen bestehenden Schaftstäben, in deren Hohlraum bei jeder Eckverbindung ein mit einer Seitenstütze verbundener Vorsprung zapfenartig eingreift und mittels einer Schraube festgeklemmt ist, und mit elastischem Schwingungsdämpfungsmaterial in den Eckverbindungen für eine Relativbeweglichkeit von Seitenstütze und Schaftstab bei hoher Belastung.The invention relates to a heald frame with releasable corner connections between the side supports and the shaft rods consisting of hollow profiles, in the cavity of which a projection connected to a side support engages in a pin-like manner and clamped by means of a screw, and with elastic vibration damping material in the corner connections for a relative mobility of each corner connection Side support and shaft rod under high loads.

Die immer höheren Tourenzahlen moderner Webmaschinen führen zu einer entsprechend höheren Beanspruchung der Webschäfte, die einem ständigen Lastwechsel ausgesetzt sind, wodurch Materialbrüche an den Seitenstützen der Webschäfte insbesondere unterhalb des jeweils zur Verbindung mit einem Schaftstab dienenden zapfenförmigen Vorsprungs der Seitenstütze auftreten können.The ever increasing number of revolutions of modern weaving machines leads to a correspondingly higher load on the heald frames which are subjected to constant load changes, as a result of which material breaks on the side supports of the heald frames can occur, in particular below the pin-shaped projection of the side support which is used in each case for connection to a shaft rod.

Zur Vermeidung von Materialbrüchen ist es aus der US-A 4,349,052 und US-A 4,741,367 bekannt, Schwingungsdämpfungsmaterial bei den Eckverbindungen zwischen Seitenstütze und Schaftstab einzusetzen. Dabei wird jedoch das Schwingungsdämpfungselement zum Festklemmen des Vorsprungs der Seitenstütze in dem Schaftstab benutzt. Ausserdem sind diese Schwingungsdämpfungselemente nicht gegen ein Verlieren beim Zerlegen des Webrahmens gesichert, sodass ein beim Lösen der Eckverbindungen auftretender Verlust einzelner Dämpfungselemente den Webrahmen zunächst einmal unbrauchbar macht.To avoid material breaks, it is known from US-A 4,349,052 and US-A 4,741,367 to use vibration damping material in the corner connections between the side support and the shaft rod. However, the vibration damping element is used to clamp the projection of the side support in the shaft rod. In addition, these vibration damping elements are not secured against loss when the weaving frame is disassembled, so that a loss of individual damping elements that occurs when the corner connections are loosened initially makes the weaving frame unusable.

Das Schwingungsdämpfungselement ist im Innern des Vorsprungs angeordnet und ist einwärts gegen zwei, den Schaftstab durchdringende Schraubbolzen oder Nietbolzen abgestützt. Zum Zerlegen des Webschaftes muss daher entweder ein separater Vorsprung, der mit Hilfe von zwei sich durch die Seitenstütze hindurch erstreckender Schrauben befestigt ist, durch Lösen dieser Schrauben entfernt werden, oder es sind bei einer anderen Ausführungsform mit einstückig mit der Seitenstütze verbundenem Vorsprung durch diesen und durch den Schaftstab sich hindurch erstreckende und die Form von lösbaren Mieten aufweisende Schraubbolzen mit konischem Kopf und ebensolchen Muttern zu lösen, wobei diese kleinen Spezialschrauben leicht verloren gehen können. Damit das Dämpfungselement zur Wirkung kommen kann und Seitenstütze sowie Schaftstab bei hoher Belastung ihre Stellung zueinander verändern können, muss zwischen dem Vorsprung der Seitenstütze und dem den Vorsprung aufnehmenden Hohlraum im Schaftstab genügend Spielraum vorhanden sein. Darum lässt sich bei dieser Konstruktion nicht eine einfache Klemmschraube zum Festsetzen des Vorpsrungs im Schaftstab verwenden, wie bei den zuerst genannten bekannten Eckverbindungen. Im Webereibetrieb ist es jedoch von vorrangiger Bedeutung, dass der Webschaft schnell und einfach zerlegbar ist.The vibration damping element is arranged in the interior of the projection and is supported inwards against two screw bolts or rivet bolts penetrating the shaft rod. To disassemble the heald frame, either a separate projection, which is fastened with the aid of two screws extending through the side support, must be removed by loosening these screws, or in another embodiment there is a projection connected integrally to the side support and this to loosen bolts with a conical head and nuts, which extend through the shaft rod and have the form of detachable rents, these small special screws being easily lost. So that the damping element can come into effect and the side support and shaft rod can change their position relative to one another under high load, there must be sufficient clearance between the projection of the side support and the cavity in the shaft rod that receives the projection. For this reason, a simple clamping screw cannot be used in this construction for fixing the pre-tension in the shaft rod, as in the known corner connections mentioned first. In weaving operations, however, it is of primary importance that the heald frame can be dismantled quickly and easily.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, für die Eckverbindung zwischen Seitenstütze und Schaftstab eines Webschaftes nur eine Klemmschraube zu verwenden, mit der der Vorsprung der Seitenstütze in der dafür vorgesehenen Ausnehmung im Schaftstab festgeklemmt werden kann. Ferner bestand die Aufgabe darin, die Schwingungsdämpfungselemente selbst nicht zum Festklemmen des Vorsprungs zu verwenden und ferner sollen die Dämpfungselemente unverlierbar angeordnet sein.The present invention was therefore based on the object of using only one clamping screw for the corner connection between the side support and shaft rod of a heald frame, with which the projection of the side support can be clamped in the recess provided in the shaft rod. Furthermore, the task was not to use the vibration damping elements themselves for clamping the projection and furthermore the damping elements should be arranged so that they cannot be lost.

Zur Lösung dieser Aufgabe weist der Webschaft die Merkmale gemäss Anspruch 1 auf. In jedem Fall besteht der Vorsprung aus zwei durch mindestens ein elastisches Schwingungsdämpfungselement voneinander getrennten starren Körpern, von denen der eine mit der Seitenstütze starr verbunden ist. Der andere Teil ist zweiteilig ausgebildet und ein Teil durchsetzt den mit der Seitenstütze starr verbundenen Körper, wobei das Schwingungsdämpfungselement sich dazwischen befindet, und ist mit einem weiteren Teil fest verbunden, z.B. vernietet, welcher Teil den mit der Seitenstütze starr verbundenen Körper mit Spiel aussen umschliesst, beispielsweise als Blechhülle, die quasi die Aussenhaut des Vorsprungs bildet und mittels einer Klemmschraube festgeklemmt werden kann.To achieve this task, the heald frame has the features according to claim 1. In any case, the projection consists of two rigid bodies separated from one another by at least one elastic vibration damping element, one of which is rigidly connected to the side support. The other part is formed in two parts and one part passes through the body rigidly connected to the side support, the vibration damping element being located in between, and is firmly connected to another part, for example riveted, which part encloses the body rigidly connected to the side support with play on the outside , for example as a sheet metal shell, which forms the outer skin of the projection and can be clamped by means of a clamping screw.

Die in Fig. 1 mit ihrem oberen Ende dargestellte Seitenstütze 1 trägt an ihrer einen Schmalseite einen Vorsprung 2, mit dessen Hilfe eine der Eckverbindungen eines Webschaftes hergestellt wird. Bei einer solchen in Fig. 3 dargestellten Eckverbindung ragt der an der Seitenstütze 1 angeordnete Vorsprung in den Hohlraum 3 eines Schaftstabes 4 des Webschaftes hinein und ist mit einer durch den Schaftstab 4 schräg hindurchgeführten Klemmschraube 5 in dem Schaftstab festgeklemmt.The side support 1 shown in FIG. 1 with its upper end has a projection 2 on one narrow side, with the aid of which one of the corner connections of a heald frame is produced. In such a corner connection shown in FIG. 3, the projection arranged on the side support 1 projects into the cavity 3 of a shaft rod 4 of the heald frame and is clamped in the shaft rod with a clamping screw 5 which is passed obliquely through the shaft rod 4.

Die in den Figuren dargestellten Ausführungsbeispiele unterscheiden sich in der Ausgestaltung des Vorsprungs, der gemäss der Erfindung aus zwei durch mindestens ein Schwingungsdämpfungselement voneinander getrennten, starren Körpern besteht, von denen der eine mit der Seitenstütze Starr verbunden ist und der andere zum Festklemmen im als Hohlprofil ausgebildeten Schaftstab dient.The exemplary embodiments shown in the figures differ in the design of the projection, which according to the invention consists of two rigid bodies separated from one another by at least one vibration damping element, one of which is connected to the rigid side support and the other of which is designed as a hollow profile for clamping Shaft rod serves.

Bei der Ausführungsform gemäss Fig. 1 und 2 ist der mit der Seitenstütze 1 starr verbundene Körper 7 ein mit der Seitenstütze einstückig ausgebildeter flacher rechteckförmiger Rahmen und ferner ist der zum Festklemmen des Vorsprungs dienende Teil bei allen Ausführungsformen mehrteilig ausgebildet und besteht bei der Ausführungsform gemäss Fig. 1 und 2 aus einem den Rahmen 7 quer durchsetzenden metallischen Teil 8, welcher von dem Rahmen 7 durch ein den Zwischenraum zwischen diesen ausfüllendes Schwingungsdämpfungselement 9 getrennt ist, und welcher Teil 8 ferner mit einem den Rahmen 7 mit Spiel aussen umschliessenden Teil 10 in Form einer U-förmig gebogenen Blechhülle fest verbunden ist. Diese Verbindung ist bei der Ausführungsform gemäss Fig. 1 und 2 mit Hilfe von drei Mieten 11 ausgeführt, durch die der Teil 8 mit der Blechhülle 10 fest verbunden ist. In die oben offene Blechhülle 10 ist ferner noch eine den oberen Abschluss bildende Leiste 12 eingenietet, um einen insgesamt stabilen Körper zu erhalten, der zum Festklemmen mittels der Klemmschraube 5 geeignet ist. Fig. 1 zeigt einen Schnitt längs der Linie 2-2 in Fig. 2, wobei die zum Einsetzen in die Blechhülle 10 etwas stufig abgesetzte Leiste 12 in ihrem oberen Abschnitt geschnitten ist.In the embodiment according to FIGS. 1 and 2, the body 7 rigidly connected to the side support 1 is a flat rectangular frame which is formed in one piece with the side support, and furthermore the part serving to clamp the projection is constructed in several parts in all embodiments and exists in the embodiment according to FIG 1 and 2 from a metallic part 8 which penetrates the frame 7 transversely and which is separated from the frame 7 by a vibration damping element 9 which fills the space between them, and which part 8 also has a part 10 in the form which surrounds the frame 7 with play a U-shaped sheet metal sleeve is firmly connected. This connection is carried out in the embodiment according to FIGS. 1 and 2 with the aid of three rents 11, through which the part 8 is firmly connected to the sheet metal casing 10. In the sheet metal casing 10, which is open at the top, there is also an upper end forming bar 12 riveted to obtain an overall stable body, which is suitable for clamping by means of the clamping screw 5. Fig. 1 shows a section along the line 2-2 in Fig. 2, wherein the slightly stepped strip 12 for insertion into the sheet metal casing 10 is cut in its upper portion.

Bei einer etwas abgewandelten Ausführungsform gemäss Fig. 1a ist der mit der Seitenstütze 1 starr verbundene Körper 7a nicht als geschlossener Rechteckrahmen, sondern U-förmig ausgebildet, sodass von der der Seitenstütze 1 gegenüberliegenden offenen Seite aus das Schwingungsdämpfungselement 9 in den Körper 7a hineinzuschieben ist. Eine die vierte Rahmenseite bildende Leiste 7b wird sodann mittels Schrauben 7c an dem U-förmigen Körper 7a festgeschraubt. Auf diese Weise kann das Schwingungsdämpfungselement 9 auch vorgespannt werden, um dadurch das Ausmass der Dämpfung zu beeinflussen. Ausserdem bietet diese Ausbildungsvariante die Möglichkeit, das mit der äusseren Blechhülle 10 verbundene Schwingungsdämpfungselement auszutauschen, wenn eine Beschädigung dies notwendig macht, oder wenn man ein Schwingungsdämpfungselement gegen ein anderes mit abweichenden Dämpfungseigenschaften austauschen will.In a somewhat modified embodiment according to FIG. 1a, the body 7a rigidly connected to the side support 1 is not designed as a closed rectangular frame, but rather in a U-shape, so that the vibration damping element 9 can be pushed into the body 7a from the open side opposite the side support 1. A bar 7b forming the fourth side of the frame is then screwed to the U-shaped body 7a by means of screws 7c. In this way, the vibration damping element 9 can also be preloaded in order to influence the extent of the damping. In addition, this design variant offers the possibility of replacing the vibration damping element connected to the outer sheet metal casing 10 if damage necessitates this, or if one wants to replace one vibration damping element with another with different damping properties.

Alle weiteren Ausführungsformen unterscheiden sich nur durch die Anzahl der vorhandenen elastischen Schwingungsdämpfungselemente und durch die daran angepasste Formgebung des mit der Seitenstütze starr verbundenen Körpers und des diesen quer durchsetzenden Teils, der mit der Blechhülle fest verbunden ist und zusammen mit dieser den zum Festklemmen dienenden Körper bildet.All other embodiments differ only in the number of existing elastic vibration damping elements and in the adapted shape of the body rigidly connected to the side support and the part passing through it, which is firmly connected to the sheet metal casing and together with this forms the body serving for clamping .

Bei der in Fig. 3 dargestellten Ausführungsform besteht der Vorsprung 2a aus einem etwas grösseren Rahmen 7a, der mit der Seitenstütze 1 starr verbunden ist, und ferner aus einem den Rahmen 7a quer durchsetzenden und in dem Rahmen über Eck gestellt angeordneten rechteckförmigen Scheibenkörper 8a, der gegen vier jeweils dreieckförmige Schwingungsdämpfungselemente 9a anliegt, welche abgerundete Ecken aufweisen und die jeweils dreieckförmigen Zwischenräume zwischen dem Rahmen 7a und dem Scheibenkörper 8a ausfüllen. Um den Zusammenbau zu erleichtern, umschliesst die Schwingungsdämpfungselemente 9a aussen noch ein schmaler Reifen 14, der bei allen Ausführungsformen vorhanden ist. Wie bei der ersten Ausführungsform gemäss Fig. 1 ist der Scheibenkörper 8a mit einer U-förmig gebogenen Blechhülle 10a vernietet, welche den Rahmen 7a mit Spiel umschliesst und oben eine eingenietete Leiste 12 enthält, um den Vorsprung 2a festklemmen zu können.In the embodiment shown in Fig. 3, the projection 2a consists of a slightly larger frame 7a, which is rigidly connected to the side support 1, and also of a rectangular through the frame 7a and arranged in the frame placed over corners Disk body 8a, which bears against four triangular vibration damping elements 9a, which have rounded corners and fill the triangular spaces between the frame 7a and the disk body 8a. In order to facilitate assembly, the vibration damping elements 9a also enclose a narrow tire 14 on the outside, which is present in all embodiments. As in the first embodiment according to FIG. 1, the disk body 8a is riveted to a U-shaped sheet metal sleeve 10a, which surrounds the frame 7a with play and contains a riveted strip 12 at the top in order to be able to clamp the projection 2a.

Eine weitere abgewandelte Ausführungsform gemäss Fig. 7-13 unterscheidet sich nur dadurch, dass bei diesem Vorsprung 2b der den gleich ausgebildeten Rahmen 7b quer durchsetzende Scheibenkörper 8b sternförmig ausgebildet ist und gegen vier die Zwischenräume in den Rahmenecken ausfüllende kreisscheibenförmige Schwingungsdämpfungselemente 9b anliegt.A further modified embodiment according to FIGS. 7-13 differs only in that, in this projection 2b, the disc body 8b passing through the same frame 7b is star-shaped and is in contact with four circular disc-shaped vibration damping elements 9b which fill the spaces in the corners of the frame.

In Fig. 8 ist nur die Blechhülle 10b allein mit der eingenieteten Leiste 12 dargestellt, die mit der Blechhülle 10a identisch ausgebildet ist. Fig. 9 zeigt die in den Rahmen 7b einzusetzende und aus dem Scheibenkörper 8b und den Schwingungsdämpfungselementen 9b bestehende und aussen mit einem Reifen 14 versehene Einheit, die in Seitenansicht in Fig. 10 dargestellt ist. Fig. 11 zeigt eine Ansicht auf die Schmalseite des an der SeitenStütze 1 angeordneten Vorsprungs 2b. Fig. 12 zeigt eine Draufsicht von oben mit der den Rahmen 7b mit Spiel umschliessenden Blechhülle 10b, während in der Draufsicht von oben gemäss Fig. 13 nur die Seitenstütze 1 mit dem einstückig mit dieser verbundenen Rahmen 7b dargestellt ist.In Fig. 8, only the sheet metal casing 10b is shown alone with the riveted bar 12, which is identical to the sheet metal casing 10a. FIG. 9 shows the unit to be inserted into the frame 7b and consisting of the disk body 8b and the vibration damping elements 9b and provided with a tire 14 on the outside, which is shown in a side view in FIG. 10. 11 shows a view of the narrow side of the projection 2b arranged on the side support 1. 12 shows a top view from above with the sheet metal casing 10b enclosing the frame 7b with play, while in the top view from above according to FIG. 13 only the side support 1 is shown with the frame 7b integrally connected to it.

Zwei weitere Ausführungsformen sind in den Figuren 4, 5 und 6 dargestellt, die sich ebenfalls nur in der Anzahl der vorhandenen Schwingungsdämpfungselemente unterscheiden. Bei der Ausführungsform gemäss Fig. 4 weist der mit der Seitenstütze 1 starr verbundene flache rechteckförmige Körper 7c diesen quer durchsetzende zylindrische Bohrungen 17 auf. Der den Körper 7c quer durchsetzende Teil besteht hier aus einer der Anzahl der vorhandenen Bohrungen entsprechenden Anzahl von im Durchmesser kleineren und konzentrisch in den Bohrungen angeordneten zylindrischen Bolzen 8c, die jeweils gegen den Zwischenraum ausfüllende ringförmige Schwingungsdämpfungselemente 9c anliegen. Bei der Ausführungsform gemäss Fig. 4 sind zwei und bei der Ausführungsform gemäss Fig. 5 sind vier ringförmige Schwingungsdämpfungselemente 9c vorhanden. Die Bolzen 8c sind wiederum mit einer äusseren Blechhülle 10c vernietet, welche den flachen Körper 7c aussen mit Spiel umschliesst. Alle Ausführungsformen erfüllen die eingangs erläuterte Funktion nach dem gleichen Prinzip, bei welchem die Schwingungsdämpfung darauf beruht, dass zwischen einem zum Festklemmen im Schaftstab des Webschaftes dienenden Körper des Vorsprungs und einem mit der Seitenstütze starr verbundenen Körper elastische Schwingungsdämpfungselemente angeordnet sind, und es ist für den Fachmann klar, dass dieses Prinzip auch durch in der Form und Anordnung anders ausgestaltete Ausführungsformen verwirklicht werden kann.Two other embodiments are in the figures 4, 5 and 6 shown, which also differ only in the number of vibration damping elements present. In the embodiment according to FIG. 4, the flat rectangular body 7c rigidly connected to the side support 1 has cylindrical bores 17 passing through it. The part passing through the body 7c here consists of a number corresponding to the number of bores present, of smaller in diameter and concentrically arranged in the bores cylindrical bolts 8c, each of which bears against the intermediate annular vibration damping elements 9c. In the embodiment according to FIG. 4 there are two and in the embodiment according to FIG. 5 there are four ring-shaped vibration damping elements 9c. The bolts 8c are in turn riveted to an outer sheet metal casing 10c, which surrounds the flat body 7c on the outside with play. All embodiments fulfill the function explained at the outset according to the same principle, in which the vibration damping is based on the fact that elastic vibration damping elements are arranged between a body of the projection serving for clamping in the shaft rod of the heald frame and a body rigidly connected to the side support, and it is for the It is clear to a person skilled in the art that this principle can also be realized by embodiments which are configured differently in shape and arrangement.
