Abstract

There is described a method and a device for the production of a wire jointed-band of alternately clockwise and counterclockwise, respectively, wound spirals of metal wire or artificial resin wire, wherein the spirals are guided to a narrow pass such that the windings providing the spirals open themselves in the area of the narrow pass and in this the parallel spirals partly are pushed into each other such that in each case one of the windings of one spiral is placed between adjacent windings of the adjacent spiral whereby the spirals thus fitted into each other are connected with each other by inserting a coupling wire into the space provided by the overlapping windings and whereby in each case several of the pairs of spirals fitted into each other are guided to the narrow space in which area the spirals are driven in the transporting direction. This is resulting in a high production speed and broad wire jointed-bands.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines Drahtgliederbandes aus abwechselnd rechtsgängig bzw. linksgängig gewickelten Wendeln aus Metalldraht oder Kunststoffdraht. Das erfindungsgemäße Verfahren geht hierbei von Verfahrensschritten aus, wonach man die Wendeln einer Engstelle zuführt derart, daß die die Wendeln ausbildenden Windungen sich im Bereich der Engstelle öffnen und die nebeneinander befindlichen Wendeln hierbei teilweise ineinander geschoben werden derart, daß sich jeweils eine der Windungen der einen Wendel zwischen benachbarten Windungen der benachbarten Wendel befindet, und wobei man die derart ineinander gesteckten Wendeln durch Einführen eines Kupplungsdrahtes in den durch die sich überlappenden Windungen ausgebildeten Raum miteinander verbindet.The invention relates to a method and a device for producing a wire link belt from alternately right-handed or left-handed coils made of metal wire or plastic wire. The method according to the invention is based on process steps, according to which the coils are fed to a constriction in such a way that the coils forming the coils open in the region of the constriction and the coils located next to one another are partially pushed into one another in such a way that one of the coils of the one is in each case Coil is located between adjacent turns of the adjacent coil, and wherein the coils thus inserted into one another are connected to one another by inserting a coupling wire into the space formed by the overlapping turns.

Ein solches Verfahren beschreibt die DE-A-30 17 378 bzw. die parallele EP-A-39 850. Die Engstelle ist dort nach Art eines Reißverschlußschiebers ausgebildet und es werden jeweils wenigstens drei der Wendeln mit einer zugfedermäßigen Vorspannung der Engstelle zugeführt. In einem bestimmten Abstand hinter der Engstelle befindet sich ein angetriebenes Walzenpaar, das auf der Oberseite und Unterseite des derart gebildeten Drahtgliederbandes aufliegt und dadurch den Transport der Wendeln sowie des anschließend gebildeten Drahtgliederbandes durch die Engstelle bewirkt. Dort ist bereits erwähnt, daß die mittlere Wendel der Engstelle auch von oberhalb zugeführt werden kann.Such a method is described in DE-A-30 17 378 and in parallel EP-A-39 850. The constriction is designed there in the manner of a zipper slide and at least three of the coils are each fed to the constriction with a tension-like preload. At a certain distance behind the constriction is a driven pair of rollers, which rests on the top and bottom of the wire link belt formed in this way and thereby causes the transport of the coils and the subsequently formed wire link belt through the constriction. It is already mentioned there that the central helix of the constriction can also be fed from above.

Das bekannte Verfahren ist jedoch mit mehreren Nachteilen behaftet. Weil drei der jeweils abwechselnd rechtsgängig bzw. linksgängig gewickelten Wendeln der Engstelle zugeführt werden, ist eine dieser Wendeln notwendigerweise lose geführt, d.h. sie hat kein Gegenstück. Nach diesem Verfahren können breite Drahtgliederbänder also nur schwierig hergestellt werden, zumindest nicht mit einigermaßen hoher Produktionsgeschwindigkeit und ohne wesentliche Fehlstellen. Dadurch bedingt, daß man auf das bereits fertig gebildete Drahtgliederband in Transportrichtung hinter der Engstelle einen Zug ausübt, öffnen sich die mit der zugfedermäßigen Vorspannung aneinander anliegenden Windungen der Wendeln im Bereich der Engstelle gegebenenfalls unterschiedlich, wobei dies insbesondere bei einem Vergleich der jeweils mittleren Wendel mit den beiden benachbarten Wendeln der Fall ist. Die seitlichen Wendeln werden durch die Engstelle etwas präziser geöffnet als die mittlere Wendel, die ihre gerade Ausrichtung nicht verläßt. Insgesamt kann also gesagt werden, daß die frei der Engstelle zugeführten Wendeln ihre Windungen dort nicht so präzise öffnen, daß auch bei höheren Produktionsgeschwindigkeiten mit Sicherheit genau eine Windung der Wendel jeweils zwischen zwei benachbarten Windungen der benachbarten Wendel gelegt wird. Vielmehr kann es vorkommen, daß beispielsweise auch zwei Windungen derselben Wendel sich in einem der Zwischenräume zwischen den Windungen der benachbarten Wendel einlegt, was natürlich zu einer Fehlstelle und damit zu Ausschuß in dem nach diesem Verfahren hergestellten Drahtgliederband führt.However, the known method has several disadvantages afflicted. Because three of the alternately right-handed or left-handed coils are fed to the narrow point, one of these coils is necessarily guided loosely, ie it has no counterpart. According to this process, wide wire link belts can only be produced with difficulty, at least not with a reasonably high production speed and without significant defects. Due to the fact that a pull is exerted on the already formed wire link belt in the transport direction behind the constriction, the turns of the coils which are in contact with one another with the tension spring pretensioning may open differently in the region of the constriction, this in particular when comparing the middle coils in each case the two adjacent coils is the case. The narrow helix opens the side coils a little more precisely than the central one, which does not leave its straight alignment. All in all, it can be said that the coils that are fed freely to the narrow point do not open their coils there so precisely that even at higher production speeds, exactly one coil of the coil is certainly placed between two adjacent coils of the adjacent coil. Rather, it can happen that, for example, two turns of the same coil are inserted in one of the spaces between the turns of the adjacent coil, which naturally leads to a defect and thus to rejects in the wire link belt produced by this method.

Die Erfindung vermeidet diese Nachteile. Ihr liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art vorzuschlagen, mit dem die Wendeln zur Herstellung des Drahtgliederbandes im Bereich der Engstelle stets in einwandfreier Weise ineinander geschoben werden, auch bei höherern Produktionsgeschwindigkeiten, und wobei sich besonders breite Drahtgliederbänder herstellen lassen.The invention avoids these disadvantages. It is based on the object of proposing a method and a device of the type mentioned at the outset with which the coils for producing the wire link belt in the area of Narrowing can always be pushed into each other in a flawless manner, even at higher production speeds, and particularly wide wire link belts can be produced.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß man jeweils mehrere ineinander gesteckte Paare der Wendeln der Engstelle zuführt, in deren Bereich man die Wendeln in der Transportrichtung antreibt.To achieve this object, the invention is characterized in that in each case a plurality of pairs of helices inserted into one another are fed to the constriction, in the area of which the spirals are driven in the transport direction.

Man vermeidet somit den nachteiligen Zug auf das bereits fertiggestellte Drahtgliederband in der Transportrichtung hinter der Engstelle; vielmehr treibt man die Wendeln selbst im Bereich der Engstelle an. Außerdem führt man der Engstelle nicht jeweils einzelne, freie Wendeln zu,sondern Wendeln, die in einem vorhergehenden Arbeitsgang bereits zu mehreren Paaren ineinander gesteckt wurden. Dadurch sind die einzelnen Windungen der Wendeln zueinander schon in den vorbestimmten Abstand gebracht und dort fixiert, weil sie eine ausreichende Vorspannung haben, damit sie in dieser Lage verbleiben. Die gewissermaßen in ihren Abständen fixierten Windungen der Wendelpaare werden demnach erfindungsgemäß der Engstelle zugeführt, wo sie problemlos ineinandergesteckt werden.This avoids the disadvantageous pull on the already finished wire link belt in the direction of transport behind the constriction; rather, you drive the coils yourself in the area of the constriction. In addition, the narrow point is not supplied with individual, free coils, but coils that were already inserted into several pairs in a previous work step. As a result, the individual turns of the coils are already spaced apart from one another and fixed there because they have sufficient pretension so that they remain in this position. The turns of the spiral pairs, which are fixed at their intervals, are accordingly fed to the narrow point where they can be inserted into one another without problems.

Weil man schon im Bereich der Engstelle selbst die Kraft für den Transport des Gebildes auf dieses ausübt, ergeben sich keine unterschiedlich starke Längungen auf die einzelnen Wendeln mit ihren Windungen, die zu den vorstehend beschriebenen Fehlstellen geführt haben. Nach diesem Verfahren lassen sich also stabile und besonders breite Drahtgliederbänder in einem Arbeitsgang herstellen. Bevorzugt wird es, wenn man die Wendelpaare der Engstelle aus unterschiedlichen Richtungen von oben bzw. von unten zuführt, weil dann das Aufbiegen der Wendeln im Bereich der Engstelle erleichtert wird.Because one already exerts the force for the transport of the structure in the area of the constriction, there are no elongations of different strengths on the individual coils with their turns, which have led to the defects described above. With this method, stable and particularly wide wire link belts can be produced in one operation. It is preferred if the helical pairs of the constriction are fed from different directions from above or from below, because then the bending of the helices in the region of the constriction is facilitated.

Fernerhin wird es bevorzugt, wenn das die Verengung der Engstelle ausbildende Bauteil die Transportkraft auf die Wendeln ausübt. Dadurch wird die Transportkraft genau an der richtigen Stelle lokalisiert, nämlich im Bereich der Engstelle selbst.Furthermore, it is preferred if the component forming the narrowing of the constriction exerts the transport force on the coils. As a result, the transport force is localized in the right place, namely in the area of the narrow point itself.

Außerdem wird es bevorzugt, wenn man auf die Wendelpaare in der Engstelle einen Druck ausübt, der im wesentlichen senkrecht zu der Ebene des dort hergestellten Drahtgliederbandes verläuft. Nachdem die Engstelle in aller Regel als Spalt ausgebildet ist, erreicht man dies also durch eine Verengung des freien Querschnitts des Spaltes in seiner Höhe bzw. Tiefe, unterschiedlich zu der bevorzugten Lehre der eingangs erwähnten DE-PS, wo die Engstelle nach Art eines Reißverschlußschiebers, d.h. an den Seitenwänden des Spalts ausgebildet wird.In addition, it is preferred if pressure is exerted on the spiral pairs in the constriction, which is essentially perpendicular to the plane of the wire link strip produced there. Since the constriction is generally designed as a gap, this is achieved by narrowing the free cross section of the gap in its height or depth, in contrast to the preferred teaching of the aforementioned DE-PS, where the constriction is in the manner of a zipper slide, ie is formed on the side walls of the gap.

Man stellt auf besonders einfache Weise ein breites Drahtgliederband her, wenn man der Engstelle mehrere seitlich zueinander versetzte Gebilde von ineinander gesteckten Spiralen abwechselnd von oben bzw. unten zuführt.A wide wire link belt is produced in a particularly simple manner if one feeds several constructions of mutually staggered spirals, which are offset laterally to one another, from the top and bottom alternately to the narrow point.

Die erfindungsgemäße Vorrichtung zur Durchführung dieses Verfahrens geht aus von einer Führungsplatte, an der eine Querschnittsverengung vorgesehen ist, die eine Engstelle für ein bandförmiges Gebilde der dort im wesentlichen nebeneinander befindlichen Wendeln ausbildet. Diese Vorrichtung beschreibt die bereits erwähnte DE-PS 30 17 378. Die Führungsplatte ist dort, wie ebenfalls bereits erwähnt, nach Art eines Reißverschlusses ausgebildet. Die Querschnittsverengung erstreckt sich dort somit in Richtung der Breite des durch die ineinander gesteckten Wendeln ausgebildeten, bandförmigen Gebildes, verbunden mit den eingangs geschilderten Nachteilen.The device according to the invention for carrying out this method is based on a guide plate on which a cross-sectional constriction is provided, which forms a constriction for a band-shaped structure of the helixes located essentially next to one another there. This before direction describes the already mentioned DE-PS 30 17 378. The guide plate is there, as also mentioned, designed like a zipper. The cross-sectional constriction thus extends there in the direction of the width of the band-shaped structure formed by the nested helices, combined with the disadvantages described at the outset.

Zur Lösung der Erfindungsaufgabe ist die erfindungsgemäße Vorrichtung daher dadurch gekennzeichnet, daß die Querschnittsverengung in Richtung der Höhe des bandförmigen Gebildes vorgesehen ist und durch einen Teil der Führungsplatte sowie durch den Umfang einer auf Drehung angetriebenen Walze ausgebildet ist.To achieve the object of the invention, the device according to the invention is therefore characterized in that the cross-sectional constriction is provided in the direction of the height of the band-shaped structure and is formed by part of the guide plate and by the circumference of a roller driven to rotate.

Die bereits paarweise ineinander gesteckten Wendeln werden der Führungsplatte mit ihrer Querschnittsverengung alternierend von oben und unten zugeführt, und zwar jeweils ein oder mehrere Paare. Um dies zu erreichen, ist die Erfindung weiterhin dadurch gekennzeichnet, daß in Transportrichtung des bandförmigen Gebildes vor der Querschnittsverengung und oberhalb und unterhalb der Ebene der Führungsplatte jeweils wenigstens eine obere bzw. eine untere Führung für die ineinander gesteckten Wendeln vorgesehen ist.The coils, which are already inserted into one another in pairs, are fed to the guide plate with their cross-sectional constriction alternately from above and below, in each case one or more pairs. In order to achieve this, the invention is further characterized in that at least one upper and one lower guide is provided for the nested coils in the transport direction of the band-shaped structure before the cross-sectional constriction and above and below the plane of the guide plate.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben. Es zeigt:

  • Fig. 1 - eine Draufsicht auf die Führungsplatte;
  • Fig. 2 - einen Schnitt längs der Linie II-II von Fig. 1 mit weiteren Bauteilen der erfindungsgemäßen Vorrichtung, wobei auch die Führung der paarweise ineinander gesteckten Wendeln und ihre Vereinigung miteinander angedeutet ist.
The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result. It shows:
  • F ig. 1 - a top view of the guide plate;
  • Fig. 2 - a section along the line II-II of Fig. 1 with further components of the device according to the invention, wherein the guidance of the coils inserted into each other in pairs and their union with each other is indicated.

In einer in den Figuren gezeigten Führungsplatte 1 sind nebeneinander und parallel zueinander mehrere Schlitze 2 angelegt. Beim Ausführungsbeispiel sind sechs derartiger Schlitze vorgesehen. Die Schlitze haben vorzugsweise eine geneigte rückwärtige Kante 3. Die Anzahl und Breite der Schlitze richtet sich nach den jeweiligen Gegebenheiten. Bevorzugt wird eine geradzahlige Anzahl der Schlitze, da sich die Gebilde dann gegenseitig besser stützen.In a guide plate 1 shown in the figures, several slots 2 are created next to one another and parallel to one another. In the exemplary embodiment, six such slots are provided. The slots preferably have an inclined rear edge 3. The number and width of the slots depend on the particular circumstances. An even number of slots is preferred since the structures then support one another better.

Jedem Schlitz 2 wird von unterhalb der Führungsplatte 1 jeweils wenigstens ein Gebilde 4, 5 von bereits paarweise ineinander gesteckten Wendeln in Richtung der Pfeile 6 zugeführt. (Zur Verdeutlichung ist in Fig. 2 nur eine einzelne Wendel 4 bzw. 5 gezeigt, die in Wirklichkeit aber jeweils ein Wendelpaar ist.)Each slot 2 is fed from below the guide plate 1 in each case at least one structure 4, 5 of helices already inserted into one another in pairs in the direction of the arrows 6. (For the sake of clarity, only a single helix 4 or 5 is shown in FIG. 2, which, however, is actually a helix pair in each case.)

Direkt über den Schlitzen 2 befindet sich eine in Richtung des Pfeiles 7 auf Drehung angetriebene Walze 8. Zusammen mit der Kante 3 bildet die Mantelfläche 9 der Walze 8 somit eine Engstelle bzw. Querschnittsverengung für das bandförmige Gebilde der vereinigten Paare 4, 5 aus. Diese Engstelle erstreckt sich also in der Höhe dieses bandförmigen Gebildes 10, d.h. in Richtung des Doppelpfeils 11. Durch die Ausbildung dieser Engstelle werden die Paare oder Gebilde 4, 5 der bereits ineinander gesteckten Wendeln in Richtung der Höhe einseitig auseinander gebogen, so daß sich die oberen Wendeln 4 nach unten öffnen und die unteren Wendeln 5 nach oben. Dadurch werden die Wendeln einwandfrei ineinander gesteckt und zu dem bandförmigen Gebilde, bestehend aus einer Reihe von mehreren, ineinander gesteckten Wendelpaaren geformt. Jeweils in ein Paar der ineinander gesteckten Wendeln wird dann von der offenen Vorderseite her noch ein Steckdraht 12 eingesteckt, der ebenfalls in Fig. 2 angedeutet ist. Bei dem gezeigten Ausführungsbeispiel besteht das nach diesem Verfahren hergestellte Drahtgliederband aus insgesamt sechsunddreißig Wendeln. Diese Anzahl kann natürlich vergrößert oder verkleinert werden, je nach den gewünschten Verhältnissen. Das fertige Drahtgliederband verläßt dann die Vorrichtung in Richtung des Pfeiles 13.Directly above the slots 2 there is a roller 8 driven to rotate in the direction of the arrow 7. Together with the edge 3, the lateral surface 9 of the roller 8 thus forms a constriction or cross-sectional constriction for the band-shaped structure of the combined pairs 4, 5. This constriction thus extends at the height of this band-shaped structure 10, ie in the direction of the double arrow 11. Due to the formation of this constriction, the pairs or structures 4, 5 of the helices already inserted into one another are bent apart on one side in the direction of the height, so that the open the upper coils 4 downwards and the lower coils 5 upwards. This will make the coils perfectly inserted into each other and formed into a band-shaped structure consisting of a series of several, inserted pairs of helices. A plug wire 12, which is also indicated in FIG. 2, is then inserted into the pair of helices inserted into one another from the open front side. In the exemplary embodiment shown, the wire link belt produced by this method consists of a total of thirty-six coils. This number can of course be increased or decreased depending on the desired conditions. The finished wire link belt then leaves the device in the direction of arrow 13.

Die Mantelfläche 9 besteht vorzugsweise aus einem geeigneten gummielastischen Material, um im Bereich der Engstelle auch die notwendige Vortriebskraft in Förderrichtung 13 auf das bandförmige Gebilde bzw. die das bandförmige Gebilde ausbildenden Wendeln auszuüben. Außerdem ist der Abstand in Richtung des Doppelpfeiles 11 zwischen der Führungsplatte 1 und der Walze 8 einstellbar in Anpassung an unterschiedlich große Wendeln. Die Platte 1 ist gegen ein andere Platte mit einer anderen Anzahl und/oder einer anderen Breite der Schlitze 2 austauschbar in Anpassung an die Breite des jeweils herzustellenden Drahtgliederbandes.The lateral surface 9 is preferably made of a suitable rubber-elastic material in order to exert the necessary propulsive force in the conveying direction 13 on the band-shaped structure or the spirals forming the band-shaped structure in the region of the constriction. In addition, the distance in the direction of the double arrow 11 between the guide plate 1 and the roller 8 can be adjusted to adapt to coils of different sizes. The plate 1 is interchangeable with another plate with a different number and / or a different width of the slots 2 in adaptation to the width of the wire link strip to be produced.

Für die Führung der Wendelpaare sorgen obere bzw. untere Führungsrollen 14,15 oder andere Führungsmittel, über die die oberen bzw. unteren Wendelpaare 4 bzw. 5 geführt sind. Beabstandet voneinander stecken auf den Führungsrollen Führungsscheiben 16, die zwischen sich jeweils einenFührungsraum für eines der Paare 4 bzw.5 ausbilden. Dadurch werden die Wendelpaare 4, 5 auch in axialer Richtung der Führungsrollen geführt.Upper and lower guide rollers 14, 15 or other guide means, via which the upper and lower pairs of spirals 4 and 5 are guided, provide guidance for the pairs of spirals. At a distance from each other, there are guide disks 16 on the guide rollers, each of which forms a guide space for one of the pairs 4 and 5, respectively. As a result, the spiral pairs 4, 5 are also guided in the axial direction of the guide rollers.

Der Antrieb für die Walze 8 kann innerhalb eines bestimmten Geschwindigkeitsbereiches feineingestellt werden. Dieser Antrieb ist zur Vereinfachung nicht dargestellt.The drive for the roller 8 can be finely adjusted within a certain speed range. This drive is not shown for simplification.

Die vorstehend erwähnten Wendelgebilde 4, 5 bestehen jeweils aus einem Wendelpaar. Bevorzugt wird es allerdings, wenn jedem Schlitz 2 mehrere der Wendelpaare zugeführt werden. Dies ist in Fig. 2 mit zusätzlichen Wendelpaaren 4a, 5a angedeutet, die der Engstelle in der Ebene der Wendelpaare 4 bzw. 5 zugeführt werden.The spiral structures 4, 5 mentioned above each consist of a spiral pair. However, it is preferred if several of the spiral pairs are fed to each slot 2. This is indicated in FIG. 2 with additional spiral pairs 4a, 5a, which are fed to the narrow point in the plane of the spiral pairs 4 and 5, respectively.

Die Paare 4, 4a sowie 5, 5a werden vor der Engstelle ebenfalls miteinander vereinigt, so daß bei diesem Beispiel jedem Schlitz vier Wendeln zugeführt werden.The pairs 4, 4a and 5, 5a are also combined with one another before the constriction, so that four coils are fed to each slot in this example.

Hat die Platte 1 z.B. sechs Schlitze 2, so führt man bei diesem Beispiel 6 x 4 = 24 Spiralen von unten zu. Die von oben zugeführten Spiralpaare, die nicht durch die Schlitze laufen, erhöhen dann die Gesamtzahl der zu dem Drahtgliederband verarbeiteten Spiralen auf 44.If the plate 1 has e.g. six slots 2, in this example 6 x 4 = 24 spirals are introduced from below. The spiral pairs fed from above, which do not run through the slots, then increase the total number of spirals processed to form the wire link belt to 44.

Führt man der Platte - bei entsprechender Verbreiterung ihrer Schlitze -eine größere Anzahl von Doppelspiralen, etwa Viererspiralen, zu, so wird das in einem Arbeitsgang gebildete Drahtgliederband wesentlich breiter und die Produktionsgeschwindigkeit erhöht. Man kann durch entsprechende Anordnung die Produktionsgeschwindigkeit beispielsweise verdoppeln.If a larger number of double spirals, for example four spirals, is fed to the plate - with corresponding widening of its slots - the wire link belt formed in one work step becomes considerably wider and the production speed increases. A suitable arrangement can double the production speed, for example.

Man kann jedem Schlitz auch noch mehr der Wendelpaare zuführen, die aber jeweils schon vor der Engstelle miteinander vereinigt sind, zumindest soweit sie der Engstelle aus einer Richtung zugeführt werden (Gebilde 4, 4a bzw. 5, 5a).It is also possible to feed even more of the spiral pairs to each slot, but these are already combined with one another before the constriction, at least insofar as they are fed to the constriction from one direction (structures 4, 4a and 5, 5a).

Wichtig ist - wegen der gegenseitigen Führung der Wendeln - auch die jeweils geradzahlige Anzahl der vor der Engstelle vereinigten Wendeln zu den Wendelpaaren, Viererwendeln, Sechserwendeln u.s.f.It is important - because of the mutual guidance of the helixes - that the even number of helixes combined in front of the constriction to the helix pairs, four-helixes, six-helixes etc. is also important.
