Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Zweikammerspule zur Aufnahme strangförmigen Gutes, wie elektrische Kabel oder Leitungen, bestehend aus den Spulenkern seitlich begrenzenden Spulenflanschen und einem den Wickelraum zwischen den Spulenflanschen in die beiden Kammern teilenden Zwischenflansch (Siehe z.B. US 4667896A).The present invention relates to a Two-chamber coil for taking up strand-like goods, such as electrical cables or lines consisting of the Coil flanges and one the winding space between the coil flanges in the intermediate flange dividing both chambers (see e.g. US 4667896A).
Spulen der gattungsgemäßen Art sind seit langem im Einsatz, hierbei kommt es darauf an, das langgestreckte Gut, das endlos bleiben soll, in die beiden Kammern so einzulegen, daß ein Abwickeln der beiden Enden in eine oder entgegengesetzte Richtungen möglich ist. Handelsübliche Zweikammerspulen, beispielsweise aus Stahl hergestellt, weisen zu diesem Zweck im Spulenkern im Bereich der einen Kammer eine Einführungsöffnung und im Bereich der zweiten Kammer eine Ausgangsöffnung für das strangförmige Gut auf. Zur Belegung des jeweiligen Wickelraumes der beiden Kammern muß nun das Kabel oder die Leitung in die Einführungsöffnung eingeführt, durch den Innenraum des Kernes weitergeleitet und durch die Ausgangsöffnung in den Wickelraum der zweiten Kammer geführt werden, bis dort die vorgesehene Kabellänge untergebracht ist. Es leuchtet ein, daß bei diesen Zweikammerspulen, insbesondere wenn es sich um ein Kabel größeren Durchmessers, mit einem erheblichen zeitlichen und personellen Aufwand gerechnet werden muß, bis die Wickelräume der beiden Kammern mit der notwendigen Kabellänge gefüllt sind.Coils of the generic type have long been in the Use, here it depends, the elongated Well, that should remain endless, in the two chambers like this to insert that unwinding of the two ends in one or opposite directions is possible. Commercial two-chamber coils, for example made of steel manufactured, have for this purpose in the coil core in Area of one chamber has an insertion opening and Area of the second chamber an exit opening for the strand-like good. For the assignment of the respective The changing room of the two chambers must now be the cable or inserted the line into the insertion opening forwarded the interior of the core and through the Exit opening into the changing room of the second chamber out until the intended cable length is housed. It is obvious that with these Dual chamber coils, especially if it is a cable larger diameter, with a considerable temporal and personnel expenditure must be expected until the Changing rooms of the two chambers with the necessary Cable length are filled.
Ausgehend von solchen handelsüblichen, gattungsgemäßen Zweikammerspulen liegt der vorliegenden Erfindung die Aufgabe zugrunde, den zeitlichen und personellen Aufwand zum Bewickeln solcher Spulen auf ein Minimum zu beschränken und gleichzeitig die Möglichkeit zu schaffen, daß die in den beiden Kammern untergebrachten Längen an langgestrecktem Gut zur Anpassung an besondere Bedingungen jederzeit veränderbar sind.Based on such commercial, generic The present invention has two-chamber coils Task based on the time and manpower to wind such coils to a minimum restrict and at the same time create the opportunity that the lengths accommodated in the two chambers elongated good for adaptation to special Conditions can be changed at any time.
Gelöst wird diese Aufgabe gemäß der Erfindung dadurch, daß der Spulenkern eine die beiden Kammern miteinander verbindende und von außen zugängliche Führungsbahn für das strangförmige Gut aufweist. Diese von außen zugängliche Führungbahn vermeidet das aufwendige Einfädeln in und das Herausführen aus dem Innern des Spulenkernes, abgesehen von dem insbesondere bei Kabeln größeren Durchmessers aufwendigen Hindurchziehens einer Länge durch den Spulenkern. Eine Veränderung der beiden in den Kammern untergebrachten Kabellängen zur Anpassung an andere Erfordernisse ist jederzeit und problemlos möglich.This object is achieved according to the invention by that the coil core one the two chambers together connecting and externally accessible guideway for has the strand-like good. This from the outside accessible guideway avoids the complex Threading into and out of the inside of the Coil core, apart from that especially with cables larger diameter complex pulling one Length through the coil core. A change in the two Cable lengths housed in the chambers for adjustment to other requirements is always and easily possible.
Als besonders vorteilhaft hat es sich in Durchführung der Erfindung erwiesen, wenn als Führungsbahn eine in die Oberfläche des Spulenkerns eingelassene und der Krümmung des Spulenkerns folgende Ausnehmung vorgesehen ist. Das Füllen der beiden Wickelräume der Zweikammerspule mit den vorgegebenen Kabellängen erfolgt dann in einfacher Weise dadurch, daß nach Auslegen der kürzeren Länge diese an ihrem Ende kreisförmig umgebogen und die so mit der in dem Wickelraum der zweiten Kammer einzuführenden Länge gebildeten Schlaufe in die in den Spulenkern eingelassene Ausnehmung eingehängt und anschließend beide Kabellängen gleichzeitig in die für sie bestimmte Kammer eingewickelt werden.It has proven to be particularly advantageous in carrying out the Invention proved if one in the guideway Surface of the coil core and the curvature the following core of the coil core is provided. The Fill the two winding spaces of the bicameral coil with the predetermined cable lengths are then carried out in a simple manner in that after laying out the shorter length this on bent at the end in a circle and so with the in the length to be inserted into the winding space of the second chamber formed loop into the recessed in the coil core Recess hooked in and then both cable lengths at the same time wrapped in the chamber intended for them will.
Da je nach den benötigten Einzellängen, die bei Bedarf aus den beiden Kammern abzuwickeln sind, unterschiedlich große Wickelräume, die durch den Zwischenflansch bestimmt werden, benötigt werden, hat es sich als vorteilhaft erwiesen, die Führungsbahn im wesentlichen von einem Spulenflansch bis zum anderen reichen zu lassen. Entsprechend einem für das jeweilige Kabel oder für die Leitung günstigen Biegeradius wird dabei die Führungsbahn kreisbogenförmig verlaufen.Since depending on the required individual lengths, which if necessary to be handled from the two chambers are different large changing rooms determined by the intermediate flange be needed, it has proven to be beneficial proven the guideway essentially by one Let the coil flange reach to the other. Corresponding to one for the respective cable or for the The guideway becomes the leader of the favorable bending radius run in a circular arc.
Die im Spulenkern vorgesehene Ausnehmung ist praktisch eine längs der Führungsbahn vorgesehene Öffnung im Kern, in die man beim Einlegen der oben als Schlaufe bezeichneten Kabellänge diese in den Kern hineingleiten läßt. Dies kann zu einer unkontrollierten Bewegung der hineingelegten Kabelschlaufe während des Transportes oder der Verlegung kommen. Aus diesem Grunde ist es besonders zweckmäßig, wenn in Weiterführung der Erfindung die Ausnehmung im Spulenkern in das Kerninnere hinein durch eine oder mehrere längs der Führungsbahn angeordnete Stützelemente für das strangförmige Gut begrenzt ist. Als Stützelement kann vorteilhaft eine durchgehende Auflage unter Bildung einer wannenartigen Führungsbahn für das Kabel oder die Leitung vorgesehen sein. Eine solche wannenartige Führungsbahn bietet sich insbesondere dann an, wenn die Zweikammerspule eine Metallspule, also beispielsweise eine Stahlspule ist, da in solchen Fällen die wannenartige Führungsbahn in die Oberfläche des Spulenkernes hineingeformt werden kann.The recess provided in the coil core is practical an opening provided in the core along the guideway, in which you insert the top as a loop designated cable length this slide into the core leaves. This can lead to an uncontrolled movement of the inserted cable loop during transport or of laying. That is why it is special expedient if in continuation of the invention Recess in the coil core into the core inside one or more arranged along the guideway Support elements for the strand-like material is limited. As Support element can advantageously be a continuous support forming a trough-like guideway for the Cable or line can be provided. Such tub-like guideway is particularly useful when the bicameral coil is a metal coil, so for example a steel coil is there in such cases the trough-like guideway into the surface of the Coil core can be molded into it.
Vorteilhaft ist es auch, wenn nach einem weiteren Erfindungsgedanken längs der Führungsbahn Befestigungsmittel für das strangförmige Gut vorgesehen sind. Solche Befestigungsmittel können beispielsweise Spannelemente sein, etwa eine Lasche mit Bügel, der nach Einlegen des Kabels in die Führungsbahn über das Kabel herüber klappbar und festschraubbar ist.It is also advantageous if after another Invention ideas along the guideway Fasteners are provided for the strand-like material are. Such fasteners can for example Be tensioning elements, such as a tab with bracket, according to Insert the cable into the guideway over the cable can be folded over and screwed down.
Der Zwischenflansch, der entsprechend seiner Stellung zwischen den beiden Spulenflanschen das Wickelvolumen der beiden Kammern bestimmt, ist vorteilhaft in Richtung des Spulenkernes bewegbar angeordnet, so daß unterschiedliche Volumina der Kammern einstellbar sind. Man kann hier beispielsweise so vorgehen, daß vor dem Einlegen der "Kabelschlaufe" in die Führungsbahn des Spulenkernes der Zwischenflansch in Richtung eines der beiden Spulenflansche geschoben, anschließend die Kabelschlaufe eingelegt und schließlich entsprechend dem gewählten Verhältnis des Wickelvolumens der beiden Kammern der Zwischenflansch zurückgeschoben wird. Eine andere, besonders vorteilhafte Variante ist die, daß der Zwischenflansch einen der Breite des aufzunehmenden Gutes entsprechenden radial verlaufenden Schlitz aufweist, dessen dem Spulenkern zugekehrtes Ende im Bereich der Führungsbahn mündet. So können die Wickelräume für die beiden Kammern von vornherein festgelegt und die zum gleichzeitigen Wickeln der beiden Enden gebildete Schlaufe durch den Schlitz im Zwischenflansch hindurchgeführt und in die Führungsbahn eingelegt werden.The intermediate flange, which corresponds to its position between the two coil flanges the winding volume of the determined two chambers, is advantageous in the direction of Coil core arranged movably so that different Volumes of the chambers are adjustable. Here, you can For example, proceed so that before inserting the "Cable loop" in the guideway of the coil core Intermediate flange towards one of the two Spool flanges pushed, then the cable loop inserted and finally according to the selected one Ratio of the winding volume of the two chambers Intermediate flange is pushed back. Another, a particularly advantageous variant is that the Intermediate flange one of the width of the goods to be picked up has a corresponding radially extending slot, whose end facing the coil core in the area of Guideway opens. So the changing rooms for the both chambers determined from the outset and the to simultaneous winding of the two ends formed Loop through the slot in the intermediate flange passed through and inserted into the guideway.
Die Erfindung sei anhand der in Figuren 1 bis 2 dargestellten Ausführungsbeispiele näher erläutert.The invention is based on that in FIGS. 1 to 2 illustrated embodiments explained in more detail.
Die Fig. 1 zeigt in einer Draufsicht eine
erfindungsgemäße Zweikammerspule 1, sie besteht aus den
das Wickelgut 2 aufnehmenden Wickelkern 3, der seitlich
begrenzt ist durch die Spulenflansche 4 und 5. Der
Zwischenflansch ist mit 6 bezeichnet, er trennt den
gesamten Wickelraum in die beiden Kammern 7 und 8. Der
Zwischenflansch 6 kann auch in Längsrichtung des
Spulenkernes verschiebbar ausgebildet sein, so daß
unterschiedliche Wickelvolumina der Kammern 7 und 8
einstellbar sind. In der Mittelachse des Spulenkernes ist
ein Verbindungs- oder Tragrohr 9 angeordnet, dieses ist
so ausgebildet, daß die Spule mit geeigneten
Vorrichtungen aufgenommen und gedreht werden kann.Fig. 1 shows a plan view
bicameral coil 1 according to the invention, it consists of the
the winding
Wie in der Fig. 1 dargestellt, ist in den Wickelräumen 7
und 8 jeweils eine unterschiedliche Menge an Wickelgut 2
untergebracht. Damit dies auf einfache Weise und ohne
großen zeitlichen und personellen Aufwand möglich ist,
wird die für die Kammer 8 vorgesehene kürzere Kabellänge
von einem nicht dargestellten Kabelvorrat abgezogen, der
Übergangsbereich zu der in der Kammer 7 unterzubringenden
Kabellänge halbkreisförmig umgebogen und diese umgebogene
Kabellänge dann in die Führungsbahn 10 eingelegt. Im
dargestellten Ausführungsbeispiel ist diese Führungsbahn
10 eine der Krümmung des Spulenkernes 3 folgende
Ausnehmung oder Öffnung in der Wand des Spulenkernes 3,
so daß die gebildete Schlaufe des Wickelgutes 2 in das
Innere des Spulenkernes 3 hineinführbar ist. Nach einer
solchen Festlegung der Schlaufe des Wickelgutes 2 werden
dann beim Drehen der Zweikammerspule in Umfangsrichtung
die beiden Enden des Wickelgutes, beispielsweise eines
Energiekabels, in die ihnen zugeordneten Kammern 7 und 8
eingeführt.As shown in FIG. 1, there is 7 in the changing rooms
and 8 each have a different amount of winding
Um zu verhindern, daß die in den Spulenkern 3 von oben
hineingelegte Kabellänge des Wickelgutes 2 während der
Umdrehungen der Zweikammerspule unkontrollierbare
Bewegungen ausführt, sind längs der Führungsbahn 10 eine
oder mehrere Klemm- oder Haltevorrichtungen 11
vorgesehen, die beispielsweise am Innern des Spulenkernes
3 befestigt sind. Dies können z. B. Stellen sein, in die
das Wickelgut 2 eingelegt und anschließend mittels eines
Bügels sowie seitlich angebrachter Klemmschrauben in
seiner Lage festgelegt wird. To prevent that in the
Eine andere vorteilhafte Möglichkeit veranschaulicht die
Fig. 2. In den Wickelkern 3, der beispielsweise ebenso
wie die zugehörigen, nicht dargestellten Flansche aus
Stahl besteht, ist eine wannenförmige Führungsbahn 12
eingeformt, in die das Wickelgut 2 von oben her im
Bereich der gebildeten Schlaufe einlegbar ist. Die Tiefe
dieser wannenartigen Führungsbahn 12 ist so gewählt, daß
die Außenfläche des Wickelgutes 2 mit der Oberfläche des
Spulenkernes 3 abschließt, so daß Verdrückungen des
Wickelgutes 2 im Bereich der Schlaufe beim anschließenden
Aufwickeln der weiteren Lage vermieden sind. Als
zweckmäßig hat es sich hierbei erwiesen, wenn zur
Festlegung des Wickelgutes 2 in der wannenförmigen
Führungsbahn 12 das Wickelgut 2 mit einem Klebestreifen
überdeckt wird, bis es durch die aufgebrachte erste Lage
der nachfolgenden Bewicklung sicher in der Führungsbahn
gehalten wird.Another advantageous possibility illustrates the
