Abstract

Proceeding from the inadequacies which occur during the alignment of the heald frame (21) in looms with individual frame guidance in the course of a frame change, there has been provided a device which is bound or not bound to the loom and which consists of a carrier element (14) having prepositioning elements (12) which are arranged over its length in a manner co-ordinated with the division of the heald-frame guides and which can be brought into engagement with each heald frame, at least one of the frame guides (1, 2) being connected to means which cause them to advance to the prepositioned heald frames. <IMAGE>

Description

Bekannt sind Webmaschinen mit an den Seitenwänden vorhandene Schaftführungen, die in das Maschineninnere vor- und zurückverstellbar angeordnet sind, und in denen die einzelnen bis zu 28 Webschäfte in Einzelschaftführungen aufgenommen und in vertikaler Richtung verschiebbar in ihnen geführt sind.
Diese Schaftführungen sind kammähnlich ausgebildet und in horizontaler Ebene vor und zurück auf Achsen verschiebbar. Für den Betreiber einer Webmaschine ist es wünschenswert, insbesondere beim Artikelwechsel, einen schnellen Schaftwechsel durchführen zu können. Das Wiedereinsetzen der Webschäfte in die einzelnen Schaftführungen erweist sich aber immer als besonders arbeitsintensiv. Beim Wiedereinsetzen der Schäfte ist nämlich jeder Einzelschaft auf den jeweiligen Führungssteg der Schaftführung auszurichten und die Schaftführung auf die Schäfte zuzustellen.
Das Ausrichten und Zustellen erfolgt in manueller und zeitaufwendiger Art und Weise.
So ist es nicht ohne weiteres möglich, beim Zustellen der Schaftführungen von Hand, die notwendigerweise zwischen der Schaftführung und dem Schaft einzuhaltende Toleranz mit einem einzigen Zustellvorgang (Heranschieben der Schaftführung) zu realisieren. Hier ist ein Manipulieren in der Art eines mehrmaligen auf den Achsen Hin- und Herbewegens der kammähnlich ausgebildeten Schaftführungen erforderlich, um alle Schäfte in die Schaftführungen zu bringen.
Aufgabe der Erfindung ist es daher, eine Vorpositionier- und Zustellvorrichtung zu schaffen, die auf einfache Weise ein Vorpositionieren der einzelnen Webschäfte in Bezug auf die jeweilige Schaftführung ermöglicht und wobei nach dem Vorpositionieren die Schaftführungen reproduzierbar mit den Einzelschäften in Eingriff bringbar sind.Weaving machines are known with shaft guides present on the side walls, which are arranged such that they can be adjusted forwards and backwards into the interior of the machine, and in which the individual up to 28 heald frames are accommodated in individual shaft guides and are guided in them in the vertical direction.
These shaft guides are comb-like and can be moved back and forth on axes in the horizontal plane. It is desirable for the operator of a weaving machine to be able to carry out a quick shaft change, especially when changing articles. The reinsertion of the heald frames into the individual shaft guides always proves to be particularly labor intensive. When the shafts are reinserted, each individual shaft must be aligned with the respective guide web of the shaft guide and the shaft guide must be positioned on the shafts.
Alignment and delivery are carried out in a manual and time-consuming manner.
For example, when the shaft guides are adjusted by hand, it is not readily possible to achieve the tolerance that must necessarily be maintained between the shaft guide and the shaft with a single infeed process (pushing the shaft guide in). Here, manipulation in the manner of repeated reciprocation on the axes of the comb-like shaft guides is required in order to bring all the shafts into the shaft guides.
The object of the invention is therefore to provide a pre-positioning and delivery device which enables the individual heald frames to be pre-positioned in a simple manner with respect to the respective shaft guide, and after the pre-positioning the shaft guides can be reproducibly brought into engagement with the individual shafts.

Erfindungsgemäß wird die Aufgabe nach dem Hauptanspruch gelöst durch eine maschinengebundene oder maschinenungebundene Vorrichtung, bestehend aus einem Trägerelement, das über seine Länge auf die Teilung "t" der Webschaftführungen abgestimmt angeordnete Vorpositionierelemente aufweist, die mit jedem Webschaft in Eingriff bringbar sind und wobei wenigstens eine der Webschaftführungen mit Mitteln verbunden ist, die ihre Zustellung auf die vorpositionierten Webschäfte bewirken. Weitere Erfindungsmerkmale ergeben sich aus den Unteransprüchen.According to the invention, the object is achieved according to the main claim by a machine-bound or machine-unbound device, consisting of a carrier element which has pre-positioning elements arranged along its length to match the pitch "t" of the heald frame guides, which can be brought into engagement with each heald frame and wherein at least one of the Heald frame guides are connected with means that deliver them to the pre-positioned heald frames. Further features of the invention result from the subclaims.

Hierdurch wird erreicht, daß beim Wechsel von Webschäften mit Einzelschaftführung, insbesondere bei deren Montage, ein schnelles und sicheres Ausrichten der einzelnen Webschäfte auf die jeweilige Webschaftführung ermöglicht wird. Damit kann auf eine "Zweimann-Montage" verzichtet werden. Nach erfolgter Vorpositionierung der Webschäfte kann mittels der erfindungsgemäßen Zustellvorrichtung das Zustellen der Schaftführungen auf die Webschäfte erfolgen. Dies kann sowohl manuell als auch maschinell in reproduzierbarer Weise geschehen. Ein empirisches und zeitaufwendiges Zustellen der Schaftführungen, wie es aus dem Stand der Technik bekannt ist, kann damit vermieden werden.This ensures that when changing heald frames with individual shaft guides, in particular during their assembly, a quick and safe alignment of the individual heald frames to the respective heald frame guide is made possible. This eliminates the need for a "two-man installation". After the heald frames have been pre-positioned, the shaft guides can be fed onto the heald frames by means of the delivery device according to the invention. This can be done both manually and mechanically in a reproducible manner. An empirical and time-consuming delivery of the shaft guides, as is known from the prior art, can thus be avoided.

In Fig. 2 ist eine obere Schaftführung 1 und eine untere Schaftführung 2 dargestellt. Beide Schaftführungen werden gem.
Fig. 1 von den Haltestreben 3 eines ersten und eines zweiten Halters 4,5 aufgenommen. Der massiv ausgebildete Teil des ersten und zweiten Halters 4,5 weist eine als Gleitführung ausgebildete Durchgangsbohrung 6 (Fig. 3) auf. In diesen Gleitführungen ist eine Achse 7 aufgenommen. Beide Achsen 7 verlaufen parallel und sind zueinander vertikal versetzt an den nicht dargestellten Seitenwänden der Webmaschine mit ihrem einen freien Ende verbunden. An dem anderen freien Ende sind die Achsen mit einer Verzahnung 8 versehen, wie Fig. 2 und 3 zeigen. Oberhalb der Durchgangsbohrung 6 jedes Halters 4,5 durchgreift quer ein mit einer Verzahnung 10 ausgerüsteter Abschnitt einer Verstellwelle 9 den massiv ausgebildeten Bereich der Halter 4,5. Die Verzahnung 10 steht mit der Verzahnung 8 der Achsen 7 in Eingriff. An einem Ende ist die Verstellwelle 9 mit einem Innensechskant versehen zum Eingreifen eines die Welle 9 in Drehbewegung setzenden Antriebes. Während die Verstellwelle 9 in Drehbewegung versetzt wird, erfolgt über die in Eingriff stehenden Verzahnungen 8,10 eine Verschiebebewegung der Schaftführungen 1,2 aus der einen Endlage kontinuierlich in Richtung auf die mittels der nachfolgend noch darzustellenden Einrichtung vorpositionierten Einzelwebschäfte.
In Fig. 1 ist an der oberen Haltestrebe 3, im wesentlichen der rückwärtigen Aufnahmefläche der oberen Schaftführung 1 gegenüberliegend und diese vertikal überragend, die maschinengebundene oder maschinenungebundene Vorpositioniervorrichtung 12 angeordnet.
Die Vorpositioniervorrichtung 12 besteht dabei aus einem mittels der Schrauben 13 mit der oberen Halterstrebe 3 verbundenen Trägerelement 14, zwischen dessen Seitenplatten 15 eine Vielzahl von z.B. schwenkbar um eine Achse 18 angeordneten Positionierelementen vorgesehen sind. Die Positionierlemente können dabei aus der strichpunktiert dargestellten Position in Fig. 2 in die nicht strichpunktiert dargestellte Position einzeln oder gruppenweise verschwenkt werden. Diese Positionierlemente bestehen aus einem zweiarmigen Schwenkhebel 16, an dessen einem Ende eine Positionierrolle 17 befestigt ist. Die Schwenkhebel 16 selbst sind um die Achse 18 schwenkbar gelagert.
Ein gruppenweises Verschwenken ist dann gegeben, wenn der die Positionierrolle 17 tragende Hebelarm des Schwenkhebels 16 z.B. in der Art einer mehrzinkigen Gabel ausgebildet ist und jede Zinke z.B. eine Positionierrolle 17 trägt. Damit würde sich die Anzahl der Einzelhebel reduzieren, ohne nachteilige Folgen in der Vorpositionierung hinnehmen zu müssen.2 shows an upper shaft guide 1 and a lower shaft guide 2. Both shaft guides are gem.
Fig. 1 of the struts 3 of a first and a second holder 4,5 is added. The solid part of the first and second holder 4, 5 has a through bore 6 (FIG. 3) which is designed as a sliding guide. An axis 7 is accommodated in these sliding guides. Both axes 7 run parallel and are connected vertically offset to one another on the side walls of the weaving machine, not shown, with one free end. At the other free end, the axes are provided with a toothing 8, as shown in FIGS. 2 and 3. Above the through bore 6 of each holder 4, 5, a section of an adjusting shaft 9 equipped with teeth 10 extends transversely through the solid area of the holder 4, 5. The toothing 10 is in engagement with the toothing 8 of the axes 7. At one end, the adjusting shaft 9 is provided with an internal hexagon for engaging a drive which sets the shaft 9 in rotary motion. While the adjusting shaft 9 is set in rotary motion, a shifting movement of the shaft guides 1, 2 takes place from the one end position continuously in the direction of the individual heald frames pre-positioned by means of the device to be shown below, via the interlocking toothings 8, 10.
In Fig. 1 is on the upper support strut 3, substantially opposite the rear receiving surface of the upper shaft guide 1 and this projecting vertically, the machine-bound or machine-independent prepositioning device 12 is arranged.
The pre-positioning device 12 consists of a carrier element 14 connected to the upper holder strut 3 by means of the screws 13, between the side plates 15 of which a plurality of positioning elements, for example pivotably arranged about an axis 18, are provided. The positioning elements can be pivoted individually or in groups from the position shown in broken lines in FIG. 2 to the position not shown in broken lines. These positioning elements consist of a two-armed pivot lever 16, at one end of which a positioning roller 17 is attached. The pivot levers 16 themselves are pivotally mounted about the axis 18.
A group-wise pivoting is given when the lever arm of the pivot lever 16 carrying the positioning roller 17 is designed, for example, in the manner of a multi-pronged fork and each prong carries, for example, a positioning roller 17. This would reduce the number of individual levers without having to accept adverse consequences in prepositioning.

Die Achse 18 verbindet mit ihren Enden die beiden Seitenplatten 15 des Trägerelementes 14. Jedes der Positionierelemente besteht aus einem um die Achse 18 schwenkbar angeordneten Doppelhebel 16. Einer der Hebelarme ist verlängert ausgebildet und trägt am freien Ende eine Positionierrolle 17. Der verkürzt ausgebildete Hebelarm weist eine Anschlagfläche 19 auf, die - wie Fig. 2 zeigt - mit der Anschlagplatte 20, welche zwischen der Halterstrebe 3 und dem Trägerelement 14 befestigt ist, in Kontakt kommt.The ends of the axis 18 connect the two side plates 15 of the carrier element 14. Each of the positioning elements consists of a double lever 16 which is arranged pivotably about the axis 18. One of the lever arms is of elongated design and carries a positioning roller 17 at the free end a stop surface 19, which - as shown in FIG. 2 - comes into contact with the stop plate 20, which is fastened between the holder strut 3 and the carrier element 14.

Die in den einzelnen Figuren dargestellten Positionierelemente können z.B. auch als das Trägerelement 14 quer zu seiner Längsachse durchdringende Stifte ausgebildet sein, die einzeln oder in Gruppen verschiebbar angeordnet sind. Es liegt also im Ermessen des Fachmannes, die Positionierelemente entsprechend auszubilden.
Wichtig ist, daß die Vorpositionierelemente in dem Trägerelement 14 derart einander beabstandet angeordnet sind, daß ihr Mittenabstand "a" der Teilung "t" entspricht, wie sie zwischen den einzelnen Führungsstegen 24 der Schaftführung 1,2 besteht und daß das Breitenmaß der Positionierrollen 17 geringer ist, als das Breitenmaß der Schaftnut 22 im Webschaft 21.The positioning elements shown in the individual figures can also be designed, for example, as pins which penetrate the carrier element 14 transversely to its longitudinal axis and which are arranged so as to be displaceable individually or in groups. It is therefore at the discretion of the person skilled in the art to design the positioning elements accordingly.
It is important that the prepositioning elements in the carrier element 14 are arranged at a distance from one another, that their center distance "a" corresponds to the pitch "t" as it exists between the individual guide webs 24 of the shaft guide 1, 2 and that the width dimension of the positioning rollers 17 is less than the width dimension of the shaft groove 22 in the heald frame 21.

In den Figuren 2 und 3 ist das Zusammenwirken der Vorpositioniervorrichtung und der Zustellvorrichtung mit einem Webschaft 21 dargestellt.
Der auf die obere und untere Schaftführung 1,2 vorzupositionierende Webschaft 21 weist in seinem außenliegenden vertikalen Schaftstreben 23 eine Schaftnut 22 auf, in die zum Zwecke seiner Führung die Führungsstege 24 der kammähnlich ausgebildeten Schaftführungen 1,2 eingreifen (Fig. 3). Die einzelnen Führungsstege 24 der Schaftführungen 1,2 sind, wie vorstehend bereits aufgeführt und allgemein bekannt, in einem Teilungsabstand "t" zueinander festgelegt (Fig. 4).The interaction of the pre-positioning device and the delivery device with a heald frame 21 is shown in FIGS.
The heald frame 21 to be pre-positioned on the upper and lower shaft guide 1, 2 has a shaft groove 22 in its outer vertical shaft struts 23, into which the guide webs 24 of the comb-like shaft guides 1, 2 engage for the purpose of its guidance (FIG. 3). As already mentioned above and generally known, the individual guide webs 24 of the shaft guides 1, 2 are fixed at a division distance "t" from one another (FIG. 4).

In den Figuren 4 bis 6 wird das Vorpositionieren und das Zustellen der Vorpositioniervorrichtung 12 zusammen mit den Schaftführungen 1,2 nochmals im einzelnen dargestellt. In Fig. 4 sind die Führungsstege 24 der oberen und unteren Schaftführungen 1,2 und die Schaftnut 22 der einzelnen Webschäfte 21 gegenüberliegend angeordnet und befinden sich nicht im gegenseitigen Eingriff, d.h. Schaftführung 1,2 und Vorpositioniervorrichtung 12 befinden sich in der hinteren Endlage auf der Achse 7. Ebenso befinden sich die einzelnen Positionierrollen 17 in ausgeschwenkter Position.In Figures 4 to 6, the pre-positioning and the delivery of the pre-positioning device 12 together with the shaft guides 1, 2 are shown again in detail. In Fig. 4, the guide webs 24 of the upper and lower shaft guides 1, 2 and the shaft groove 22 of the individual heald frames 21 are arranged opposite one another and are not in mutual engagement, i.e. The shaft guide 1, 2 and pre-positioning device 12 are in the rear end position on the axis 7. Likewise, the individual positioning rollers 17 are in the pivoted-out position.

In Fig. 5 befinden sich die Schaftführungen 1,2 und die Vorpositioniervorrichtung 12 weiterhin in der hinteren Endlage auf der Achse 7, jedoch sind die Positionierelemente, d.h. die Schwenkhebel 16 und die Positionierrollen 17 in die Schaftnut 22 des jeweiligen Webschaftes 21 eingeschwenkt.
Damit ist der jeweilige Webschaft 21 auf die Führungsstege 24 der Schaftführungen 1,2 vorpositioniert.
Fig. 6 zeigt im Vergleich zu Fig. 5 das Maß "z" der Zustellung der Schaftführungen 1,2 mit der Vorpositioniervorrichtung 12 in Richtung auf die vorpositionierten Webschäfte 21.
In dieser Darstellung sind die einzelnen Webschäfte 21 in die Schaftführungen 1,2 aufgenommen und hinsichtlich ihrer weiteren Funktion festgelegt. Die Vorpositioniervorrichtung kann nun aus ihren Aufnahmen an der Webmaschine entnommen und als sogenannte maschinenungebundene Einrichtung zur Vorpositionierung an anderen Webmaschinen mit Einzelschaftführung eingesetzt werden.5, the shaft guides 1, 2 and the pre-positioning device 12 are still in the rear end position on the axis 7, but the positioning elements, ie the pivot levers 16 and the positioning rollers 17, are pivoted into the shaft groove 22 of the respective heald frame 21.
The respective heald frame 21 is thus pre-positioned on the guide webs 24 of the shaft guides 1, 2.
6 shows the dimension "z" of the infeed in comparison to FIG. 5 the shaft guides 1, 2 with the pre-positioning device 12 in the direction of the pre-positioned heald frames 21.
In this illustration, the individual heald frames 21 are received in the shaft guides 1, 2 and are defined with regard to their further function. The prepositioning device can now be removed from its receptacles on the weaving machine and used as a so-called machine-independent device for prepositioning on other weaving machines with individual shaft guidance.
