Abstract

Method for producing a self-supporting bundle from strand-like material, this strand-like material being wound in a plurality of layers onto an essentially conical winding reel. The layers are inclined relative to the longitudinal axis of the winding reel. The first layer contains N1 turns, whilst the next layer, wound in the same direction as the first layer, contains N1 + DELTA N turns. The number of turns in each winding layer wound in the same direction is increased in the same way, until the total number of possible turns at the selected winding pitch is reached. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines spulenlosen Gebindes aus strangförmigem Gut, wie beispielsweise Draht, isolierten oder nichtisolierten Litzen, Glasfasern und dergleichen, sowie eine Vorrichtung zur Durchführung des Verfahrens.The present invention relates to a method for producing a bobbinless package from strand-like material, such as wire, insulated or non-insulated strands, glass fibers and the like, and an apparatus for carrying out the method.

Bei der Verarbeitung von strangförmigem Gut, wie z. B. bei Draht, entsteht in der Regel das Problem, daß die Weiterverarbeitung des Drahtes nicht an der Stelle und oft auch nicht in dem Betrieb erfolgt, in dem der Draht selbst hergestellt worden ist. Das strangförmige Gut muß dann in geeigneter Weise für den Transport bereitgemacht und zur Verarbeitungsstelle gebracht werden.When processing strand-like material, such as. B. with wire, there is usually the problem that the further processing of the wire does not take place at the point and often not in the operation in which the wire itself was produced. The strand-like material must then be suitably prepared for transport and brought to the processing point.

Dies geschieht üblicherweise, indem das Wickelgut auf Spulen gewickelt wird, die dann gemeinsam mit dem Wickelgut transportiert werden. In den entsprechenden Betrieben muß deshalb eine große Anzahl von Spulen vorgehalten werden, was einen beträchtlichen Investitionsaufwand erfordert. Weiterhin müssen die leeren Spulen von der Verarbeitungsstelle zum Produktionsbetrieb zurücktransportiert werden, wodurch erhebliche Kosten entstehen. Schließlich erhöhen die Spulen auch das Transportgewicht des Wickelgutes, was ebenfalls eine Erhöhung der Transportkosten mit sich bringt.This is usually done by winding the material to be wound on spools, which are then transported together with the material to be wound. A large number of coils must therefore be kept in the corresponding factories, which requires a considerable investment. Furthermore, the empty bobbins have to be transported back from the processing point to the production plant, which results in considerable costs. Finally, the coils also increase the transport weight of the winding material, which also entails an increase in the transport costs.

Es ist deshalb ein Wunsch der entsprechenden Industrie, daß strangförmiges Gut, wie z. B. Draht, nicht auf Spulen aufgewickelt, sondern als Gebinde transportiert und geliefert wird, welches im wesentlichen nur aus dem eigentlichen strangförmigen Gut selbst besteht. Diese Art von Gebinden wird üblicherweise als einweg-verpacktes Gebinde bezeichnet.It is therefore a desire of the industry concerned that strand-like material such. B. wire, not wound on spools, but is transported and delivered as a bundle, which essentially consists only of the actual strand-like good itself. This type of packaging is usually referred to as a single-use packaging.

Mit der DE-OS 35 20 195 ist ein Verfahren zur Herstellung eines einwegverpackten Gebindes bekannt geworden.DE-OS 35 20 195 a method for producing a disposable pack has become known.

Bei diesem bekannten Verfahren wird eine kegelförmige Wikkelspule verwendet. Das strangförmige Gut wird dann in einzelnen, zueinander parallelen Lagen auf diese kegelförmige Wickelspule gewickelt, wobei ein Haftmittel vorgesehen wird, das die einzelnen Windungen und Lagen klebend miteinander verbindet. Bei der Weiterverarbeitung wird dann der Draht von innen abgezogen.In this known method, a conical winding coil is used. The strand-like material is then wound in individual, parallel layers on this conical winding spool, an adhesive being provided which adhesively connects the individual turns and layers. The wire is then removed from the inside during further processing.

Dieses bekannte Verfahren und das dadurch entstehende Gebinde haben eine Reihe von erheblichen Nachteilen.This known method and the resulting container have a number of significant disadvantages.

Nachteilig ist zunächst die Tatsache, daß zur Herstellung des Gebindes ein Haftmittel benötigt wird, was das Verfahren kompliziert und teuer macht. Weiterhin kann dieses Haftmittel zu einer Störung des Weiterverarbeitungsprozesses führen und muß deshalb u. U. zuerst entfernt werden.The first disadvantage is the fact that an adhesive is required to produce the container, which makes the process complicated and expensive. Furthermore, this adhesive can lead to a disruption of the processing process and must therefore u. May be removed first.

Außerdem kann es trotz Haftmittels zu einem Verheddern der Drahtlagen führen, wenn nämlich gegen Ende des Abzugsvorganges, zwischen einzelnen Lagen die Haftkräfte überschritten werden, so daß mehrere Windungen auf einmal nach unten fallen.In addition, in spite of the adhesive, the wire layers can get tangled, namely when the adhesive forces between individual layers are exceeded towards the end of the removal process, so that several turns fall down at once.

Ein Verfahren gemäß dem Oberbegriff des Anspruches 1 ist mit der EP-A-0 241 964 bekannt geworden. Die 3. Figur dieser Druckschrift zeigt eine Wickelspule, die einen konischen Wickelkern und zwei konisch gestaltete Flansche aufweist. Die Bewicklung beginnt an dem Flansch, der am größeren Durchmesser des konischen Wickelkernes liegt und wird mit zunehmend ansteigender Windungszahl durchgeführt. Dabei entsteht ein Wicklungsaufbau, bei dem sich die einzelnen Windungen gegen den konischen Kern des Wickelkernes abstützen. Im Unterschied zum Verfahren gemäß der vorliegenden Erfindung dient dieser Wicklungsaufbau allerdings nicht zum Herstellen eines spulenlosen Gebindes. Die gesamte Wickelspule und das darauf gewickelte Gut wird vielmehr als eine Einheit transportiert, wozu der untere Teil der Wickelspule unmittelbar palettenähnlich ausgestaltet ist. Weiterhin sind die Flansche deshalb konisch gestaltet, damit beim Abzug des Wickelgutes über den Flansch hohe Spannungen und Reibungswerte, die zum Bruch des Wickelgutes führen können, vermieden werden.A method according to the preamble of claim 1 is known from EP-A-0 241 964. The third figure of this document shows a winding spool which has a conical winding core and two conically shaped flanges. The winding begins on the flange, which is due to the larger diameter of the conical winding core, and is carried out with an increasing number of turns. This creates a winding structure in which the individual turns are supported against the conical core of the winding core. In contrast to the method according to the present invention, however, this winding structure is not used to produce a package without a coil. The entire winding bobbin and the material wound thereon are rather transported as a unit, for which purpose the lower part of the winding bobbin is designed directly like a pallet. Furthermore, the flanges are designed conical so that high tensions and friction values, which can lead to breakage of the winding material, are avoided when the winding material is drawn off via the flange.

Die vorliegende Erfindung stellt sich die Aufgabe, ein Verfahren zur Herstellung eines spulenlosen Gebindes zur Verfügung zu stellen, welches einfach und kostengünstig durchzuführen ist und welches zu einem stabilen, ohne Probleme transportierbaren und verarbeitbaren Gebinde führt. Ferner soll eine Vorrichtung zur Durchführung dieses Verfahrens angegeben werden.The object of the present invention is to provide a method for producing a package without a coil, which is simple and inexpensive to carry out and which leads to a stable, easily transportable and processable package. Furthermore, an apparatus for performing this method is to be specified.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruchs 1 gelöst. Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens ist Gegenstand des Anspruch 20. Das durch das Verfahren erzeugte Gebinde ist Gegenstand des Anspruchs 12. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved according to the invention by the subject matter of claim 1. The device according to the invention for carrying out the method is the subject of claim 20. The container produced by the method is the subject of claim 12. Advantageous further developments are the subject of the subclaims.

Mit dem erfindungsgemäßen Verfahren wird eine Möglichkeit zur Herstellung von einwegverpackten Gebinden aus strangförmigem Gut zur Verfügung gestellt, welche gegenüber den im Stand der Technik bekannten Verfahren erhebliche Vorteile aufweist. Durch die besondere Steuerung der Wicklung wird es möglich, Gebinde zu schaffen, welche in der Art eines Doppelkegels gebildet sind, so daß sich die einzelnen Windungen gegeneinander abstützen können. Dadurch wird der Aufbau des Gebindes für den Transport wesentlich stabiler, ohne daß es dazu eines Haftmittels bedürfte.With the method according to the invention, a possibility is provided for the production of single-use packs from strand-like material, which has considerable advantages over the methods known in the prior art. The special control of the winding makes it possible to create containers which are formed in the manner of a double cone, so that the individual turns can be supported against one another. This makes the structure of the container much more stable for transportation without the need for an adhesive.

Das erfindungsgemäße Verfahren führt weiterhin dazu, daß das fertiggestellte Gebinde auf besonders einfache und sichere Weise abgewickelt werden kann. So ist es prinzipiell möglich, das Gebinde sowohl von innen als auch von außen abzuziehen. Beim Innenabzug wird das Gebinde üblicherweise so angeordnet, daß die Längsachse des Gebindes senkrecht ist und sich der größere Innendurchmesser des Gebindes unten befindet. Wird dieser Draht dann von innen abgezogen, wird aufgrund der durch die kegelförmige Wickelspule gegebene Neigung jede Drahtwindung von der darunterliegenden Drahtwindung gestützt, so daß die Drahtwindungen nicht nach unten fallen können.The method according to the invention also means that the finished container can be handled in a particularly simple and safe manner. In principle, it is possible to remove the container from both the inside and the outside. In the case of internal extraction, the container is usually arranged in such a way that the longitudinal axis of the container is vertical and the larger inner diameter of the container is at the bottom. If this wire is then withdrawn from the inside, each wire winding is supported by the underlying wire winding due to the inclination given by the conical winding coil, so that the wire windings cannot fall down.

Besonders vorteilhaft kann aber hier auch eine Außenabzugsmethode angewendet werden, die mit den im Stand der Technik bekannten Gebinden nicht durchgeführt werden kann. Bei dieser Methode wird das Gebinde ebenfalls mit seiner Längsachse in senkrechter Richtung angeordnet und zwar so, daß sich der kleinere Innendurchmesser des Gebindes unten befindet. Anschließend wird auf das Gebinde eine Abzugsscheibe aufgelegt, deren Durchmesser gleich groß oder größer ist, als der Außendurchmesser des Gebindes, und die sich vorzugsweise drehen kann. Das strangförmige Gut, d. h. z. B. der Draht, wird dann "über Kopf" abgezogen, d. h. er wird an dieser Scheibe vorbeigeführt. Auch bei dieser Abzugsform wird das Gebinde so abgezogen, daß die Windungen sich gegenseitig abstützen, so daß jede Windung von einer weiter unten liegenden Windung gestützt wird, deren Wickeldurchmesser größer ist, als der Durchmesser der vorausgehenden Windung. Dadurch kann die obere Windung nicht nach unten rutschen.However, it is also particularly advantageous here to use an external extraction method which cannot be carried out with the containers known in the prior art. In this method, the container is also arranged with its longitudinal axis in the vertical direction, in such a way that the smaller inside diameter of the container is at the bottom. A pull-off disk is then placed on the container, the diameter of which is equal to or larger than the outer diameter of the container, and which preferably rotate can. The strand-like material, ie the wire, for example, is then pulled off "overhead", ie it is guided past this disk. In this form of withdrawal, too, the container is drawn off in such a way that the turns support one another, so that each turn is supported by a turn lying further down, the winding diameter of which is larger than the diameter of the preceding turn. This prevents the upper turn from sliding down.

Das Gebinde bleibt also auch beim Außenabzug in einem sehr stabilen Zustand, was es ermöglicht, den Abzugsvorgang beliebig zu unterbrechen und wieder aufzunehmen, ohne daß befürchtet werden muß, daß während des Stillstandes Windungen verrutschen und sich das strangförmige Gut dadurch verheddert.The container thus remains in a very stable condition even when the outer trigger is removed, which makes it possible to interrupt the take-off process as desired and to resume it without fear that windings will slip during standstill and the strand-like material will get tangled as a result.

Die hohe Stabilität des Gebindes erleichtert auch den Transport wesentlich.The high stability of the container also makes transportation much easier.

Das erfindungsgemäße Verfahren kann mit sehr unterschiedlichem strangförmigen Gut durchgeführt werden. Erwähnt ist schon das Aufwickeln von Draht, für das sich dieses Verfahren besonders eignet. Weiterhin, wurde eine hohe Eignung des Verfahrens für das gleichzeitige Aufwickeln von mehreren, verdrillten oder unverdrillten Drähten festgestellt. Das Erfüllen dieser Anforderung ist ein besonderer Vorteil dieses Verfahrens, da das gleichzeitige Aufwickeln von mehreren Drähten, die anschließend wieder abgewickelt und getrennt werden müssen, bei der Drahtfertigung heute eine wichtige Rolle spielt.The method according to the invention can be carried out with very different strand-like material. The winding of wire for which this method is particularly suitable is mentioned. Furthermore, a high suitability of the method for the simultaneous winding of several, twisted or untwisted wires was found. The fulfillment of this requirement is a particular advantage of this method, since the simultaneous winding of several wires, which then have to be unwound and separated, plays an important role in wire production today.

Weiterhin ist es möglich, mit diesem Verfahren auch bereits fertige Litzen, und auch isolierte Litzen und dergleichen Kabel aufzuwickeln. Außerdem können auch Glasfasern auf diese Art aufgewickelt werden.It is also possible with this method to wind up already finished strands and also insulated strands and similar cables. Glass fibers can also be wound up in this way.

In einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens, kann sich die Wickelspule während des Wickelvorgangs drehen. In diesem Fall wird dann eine sich auf- und abwärts bewegende Verlegerolle verwendet, die das strangförmige Gut in der jeweils gewünschten Höhe zur Spule führt. Infolge der Drehung der Wickelspule, wird ein drallfreies Aufwickeln des Wickelgutes ermöglicht. Es soll darauf hingewiesen werden, daß sich bei dieser Ausführungsform die Drehzahl der Wickelspule mit der Veränderung der Lage der Verlegeeinrichtung ändern muß, um sicherzustellen, daß bei konstanter Drahtzuführungsgeschwindigkeit jeder Durchmesser der Wickelspule die gleiche Umfangsgeschwindigkeit aufweist.In an advantageous development of the method according to the invention, the winding spool can rotate during the winding process. In this case, an up and down moving laying roller is used, which leads the strand-like material to the coil at the desired height. As a result rotation of the winding spool, a twist-free winding of the winding material is made possible. It should be noted that in this embodiment, the speed of the winding spool must change with the change in the position of the laying device to ensure that at constant wire feed speed, each diameter of the winding spool has the same peripheral speed.

Gemäß einer weiteren zu bevorzugenden Ausführungsform steht die Wickelspule während des Wickelvorgangs still. In diesem Fall bewegt sich die Verlegeeinrichtung um die Spule herum und legt den Draht entsprechend den Merkmalen des erfindungsgemäßen Verfahrens um die Wickelspule. Das strangförmige Gut weist dann im allgemeinen einen Drall auf, da das Gut bei jeder Windung um 360° gedreht wird. Dieser Drall kann beim Abwickeln der Spule wieder entfernt werden, indem das Abwikkeln oder das Abflyern in der entsprechend entgegengesetzten Richtung erfolgt. Falls der Drall für die Weiterverarbeitung erwünscht ist, z. B. bei der Herstellung von Litzen, kann der Drall beim Abziehen um eine weitere Umdrehung pro Windung verstärkt werden.According to a further preferred embodiment, the winding spool is stationary during the winding process. In this case, the laying device moves around the spool and places the wire around the winding spool in accordance with the features of the method according to the invention. The strand-like material then generally has a twist, since the material is rotated through 360 ° with each turn. This twist can be removed when the spool is being unwound by unwinding or flaying in the opposite direction. If the twist is desired for further processing, e.g. B. in the manufacture of strands, the twist can be increased by a further revolution per turn when pulling.

Gemäß einer weiteren zu bevorzugenden Ausführungsform des Verfahrens werden nach Erreichung der Maximalwindungszahl Nmax, d. h. sobald die erste Lage den dem Anfangsflansch gegenüberliegenden Flansch der Wicklungsspule erreicht hat, Wickellagen aufgebracht, die zu dieser letzten Lage parallel sind. Dadurch wird die vorteilhafte, geneigte Form der Wicklung beibehalten.According to a further preferred embodiment of the method, after reaching the maximum number of turns N max , ie as soon as the first layer has reached the flange of the winding coil opposite the starting flange, winding layers are applied which are parallel to this last layer. This maintains the advantageous, inclined shape of the winding.

Gemäß einer weiteren zu bevorzugenden Ausführungsform, wird, sobald ein Teil der Wickellage den maximalen Durchmesser des Spulenflansches auf der einen Seite erreicht, die Wicklung so weitergeführt, daß letztlich ein zylindrisches Gebilde entsteht. Zu diesem Zweck wird die Verlegeeinrichtung praktisch in der gleichen Weise gesteuert wie bei Beginn der Verlegung, nur mit dem Unterschied, daß nun die Windungszahlen entsprechend abnehmen. Diese Ausführungsform des Verfahrens hat den Vorteil, daß das Volumen des Gebindes besser ausgenutzt wird.According to a further preferred embodiment, as soon as a part of the winding layer reaches the maximum diameter of the coil flange on one side, the winding is continued in such a way that a cylindrical structure ultimately results. For this purpose, the laying device is controlled practically in the same way as at the beginning of the laying, with the difference that the number of turns decreases now accordingly. This embodiment of the The method has the advantage that the volume of the container is better used.

Wie in Anspruch 1 erläutert, wird das Verfahren so durchgeführt, daß zunächst eine Lage L1a mit der Wicklungszahl N₁ gewickelt wird. Sobald die Zahl N₁ erreicht ist, wird die Bewegungsrichtung der Verlegerolle umgekehrt und es wird eine Lage L1b zum Ausgangspunkt der ersten Lage L1a zurückgewickelt, die im wesentlichen ebenfalls die Windungszahl N₁ aufweist. Die nächste Lage L2a, die in die gleiche Richtung gewickelt wird, wie die Lage L1a, weist eine Anzahl N₂ > N₁ Windungen auf, wobei die Differenz zwischen der Anzahl N₂ und der Anzahl N₁ dem Wickelfaktor Δ N entspricht. Dieser Wickelfaktor wird im wesentlichen bei allen darauffolgenden Wicklungen beibehalten, so daß sich, wie gewünscht, der zu bevorzugende kegelförmige Aufbau der Windungen ergibt. D. h. also, daß die Windungszahl N₃ der Lagen L3a und L3b wiederum um den Wickelfaktor Δ N erhöht wird usw.As explained in claim 1, the method is carried out so that first a layer L 1a is wound with the number of windings N₁. As soon as the number N 1 is reached, the direction of movement of the laying roller is reversed and a layer L 1 b is wound back to the starting point of the first layer L 1 a , which also essentially has the number of turns N 1. The next layer L 2a , which is wound in the same direction as the layer L 1a , has a number of N₂> N₁ turns, the difference between the number N₂ and the number N₁ corresponds to the winding factor Δ N. This winding factor is essentially maintained in all subsequent windings, so that, as desired, the preferred conical structure of the turns results. That is, so that the number of turns N₃ of the layers L 3a and L 3b is again increased by the winding factor Δ N etc.

Gemäß einer zu bevorzugenden Ausführungsform, liegt der Wikkelfaktor zwichen 2 und 6, vorzugsweise zwischen 3 und 5. Für diesen Wickelfaktor wird ein Kegelöffnungswinkel zwischen 12 und 16°, vorzugsweise zwischen 13 und 15° bevorzugt. Unter Kegelöffnungswinkel wird hier der Gesamtöffnungswinkel der Wickelspule während des Wickelvorganges verstanden. D. h. also, daß bei einem Kegelöffnungswinkel von z. B. 16°, die Mantellinie des Kegels im Achsschnitt um 8° zur Längsachse der Wickelspule geneigt ist.According to a preferred embodiment, the winding factor is between 2 and 6, preferably between 3 and 5. For this winding factor, a cone opening angle between 12 and 16 °, preferably between 13 and 15 °, is preferred. The cone opening angle here means the total opening angle of the winding spool during the winding process. I.e. So that at a cone opening angle of z. B. 16 °, the generatrix of the cone in the axial section is inclined by 8 ° to the longitudinal axis of the winding spool.

Gemäß einer weiteren, zu bevorzugenden, Ausführungsform, liegt der Wickelfaktor zwischen 6 und 12, vorzugsweise zwischen 7 und 11. Bei diesem Wickelfaktor wird vorzugsweise ein Öffnungswinkel des Kegels verwendet, der zwischen nahe 0° und 12° liegt.According to a further preferred embodiment, the winding factor is between 6 and 12, preferably between 7 and 11. In this winding factor, an opening angle of the cone is preferably used which is between close to 0 ° and 12 °.

Das erfindungsgemäße Verfahren kann mit unterschiedlicher Wickelsteigung, das ist der Abstand zweier benachbarter Windungen zueinander, bezogen auf den Durchmesser des Wickelgutes, durchgeführt werden. Zu bevorzugen ist eine Wickelsteigung von 1,5 bis 3. Diese Wickelsteigung hat den Vorteil, daß kleinere Abweichungen der Drahthöhe beim Verlegen und beim Abziehen die Stabilität des Gebindes nicht beeinträchtigen können.The method according to the invention can be carried out with a different winding pitch, that is to say the distance between two adjacent windings from one another, based on the diameter of the material to be wound. A winding pitch is preferred from 1.5 to 3. This winding pitch has the advantage that minor deviations in the wire height when laying and pulling off cannot impair the stability of the container.

Die Durchführung des erfindungsgemäßen Verfahrens und der Aufbau der erfindungsgemäßen Vorrichtung wird beispielhaft anhand der Figuren 1 - 4 beschrieben, wobei hier die Ausführungsform mit einer drehenden Wickelspule vorgesehen ist. Die Vorrichtung besteht aus dem eigentlichen Wickelkern 1, der konisch gestaltet ist und einen Kegelöffnungswinkel aufweist, der schematisch mit 2 bezeichnet ist. Die Wickelspule weist ferner einen ersten Flansch 3 und einen zweiten Flansch 4 auf, wobei beide Flansche senkrecht zur Längsachse 5 der Wickelspule angeordnet sind. Die beiden Flansche sind scheibenförmig gestaltet und haben keine kegeligen Flächen. Der zweite Flansch 4 ist abnehmbar, so daß die Wickelspule aus dem fertigen Gebinde entfernt werden kann. Weiterhin ist die Wickelspule vorzugsweise teilbar gestaltet, um das Herausführen der Wickelspule zu vereinfachen.The implementation of the method according to the invention and the construction of the device according to the invention is described by way of example with reference to FIGS. 1-4, the embodiment with a rotating winding spool being provided here. The device consists of the actual winding core 1, which is conical and has a cone opening angle, which is denoted schematically by 2. The The winding bobbin also has a first flange 3 and a second flange 4, both flanges being arranged perpendicular to the longitudinal axis 5 of the winding bobbin. The two flanges are disc-shaped and have no conical surfaces. The second flange 4 is removable so that the winding spool can be removed from the finished container. Furthermore, the winding spool is preferably designed to be divisible in order to simplify the removal of the winding spool.

Auf die Wickelspule wird eine dünne Hülle 10 aufgebracht, welche der Kontur der Wickelspule angepaßt ist, und welche z. B. aus Papier bestehen kann. Diese dünne Hülle 10 verbleibt nach der Fertigstellung des Gebindes und erhöht dessen Festigkeit beim Transport, bzw. beim Außenabzug.On the winding spool a thin sleeve 10 is applied, which is adapted to the contour of the winding spool, and which z. B. can consist of paper. This thin casing 10 remains after the completion of the container and increases its strength during transport or when the external trigger is removed.

Die Verlegung des strangförmigen Gutes, im vorliegenden Fall ein Draht, beginnt an dem Flansch der Wickelspule, der an dem Teil der Wickelspule angeordnet ist, welches den kleinsten Durchmesser aufweist. Der Draht 12 wird aus Gründen, die nachfolgend näher beschrieben werden, zunächst lose über den zweiten Flansch 4 geführt, die Verlegung beginnt dann mit der Drahtwindung 20, die die erste an die Wickelspule geführte Wicklung darstellt. nie Verlegung erfolgt mit einer Verlegerolle 21, die gesteuert auf- und abwärts bewegt wird, und die den im wesentlichen mit konstanter Geschwindigkeit ankommenden Draht 13 der rotierenden Wickelspule zuführt. Die Steuerung der Verlegerolle 21 läßt sich am besten an Bild 2 erkennen. Die Verlegung beginnt mit der Verlegung der Lage L1a, wobei im vorliegenden Fall 4 Windungen in Richtung des Pfeiles 22 gewickelt werden. Anschließend kehrt die Verlegerolle ihre Bewegungsrichtung um und wickelt 4 Windungen zurück, welche die Lage L1b bilden. Die Wicklungszahl N₁ der Lage 1 ist damit 4. Anschließend wird die Lage L₂ gewickelt, wobei sich die Anzahl N₂ der Windungen aus der Gleichung: N x = N x - 1 + Δ N

Figure imgb0001
errechnet. Im vorliegenden Fall ist Δ N = 4, d. h., zufälligerweise gleich der Anzahl N₁ der ersten Lage L₁. Die Lage L2a enthält deshalb 8 Wicklungen, die in Richtung des Pfeils 22 gewickelt werden, die Lage L2b enthält dann ebenfalls 8 Wicklungen, die in Richtung des Pfeiles 23 gewickelt werden. Die nächste Lage L3a hat dann N₂ + Δ N = 8 + 4 = 12 Wicklungen, die nicht dargestellte Lage L4a hätte dann 16, die Lage L5a dann 20 usw.. Die Anzahl der Wicklungen wird also bei jeder neuen, in der gleichen Richtung gewickelten Lage, um einen konstanten Betrag erhöht. Selbstverständlich könnte man diesen Betrag auch variieren, wenn dies zum Aufbau des Gebindes vorteilhafter ist.The laying of the strand-like material, in the present case a wire, begins at the flange of the winding spool, which is arranged on the part of the winding spool which has the smallest diameter. For reasons that will be described in more detail below, the wire 12 is first loosely guided over the second flange 4, the laying then begins with the wire winding 20, which represents the first winding led to the winding spool. never laying is carried out with a laying roller 21, which is moved up and down in a controlled manner and which feeds the wire 13 arriving at a substantially constant speed to the rotating winding spool. The control of the laying roller 21 can best be seen in Figure 2. The laying begins with the laying of the layer L 1a , 4 windings being wound in the direction of the arrow 22 in the present case. Then the laying roller reverses its direction of movement and winds back 4 turns, which form the layer L 1b . The number of windings N 1 of the layer 1 is 4. Then the layer L 2 is wound, the number N 2 of the turns being derived from the equation: N x = N x - 1 + Δ N
Figure imgb0001
 calculated. In the present case, Δ N = 4, ie, coincidentally equal to the number N 1 of the first layer L 1. The layer L 2a therefore contains 8 windings which are wound in the direction of the arrow 22, the layer L 2b then likewise contains 8 windings which are wound in the direction of the arrow 23. The next layer L 3a then has N₂ + Δ N = 8 + 4 = 12 windings, the layer L 4a not shown would then have 16, the layer L 5a then 20, etc. The number of windings is therefore with each new one in the same direction wound position, increased by a constant amount. Of course, one could also vary this amount if this is more advantageous for the assembly of the container.

Die Fortführung des Wickelvorganges wird am besten anhand der Bilder 3 und 4 deutlich. Der Verlegevorgang wird in der beschriebenen Weise weitergeführt, bis schließlich die Anzahl der Windungen so hoch ist, daß der gegenüberliegende erste Flansch 3 mit den Windungen erreicht wird. Sobald dieser Punkt erreicht ist, werden die folgenden Lagen mit der gleichen Wicklungszahl gewickelt, wodurch sich parallel verlaufende Lagen von Draht ergeben. Dieser Verlauf der Wicklungen ist schematisch durch parallel verlaufende gestrichelte Linien 25 in Bild 3 dargestellt.The continuation of the winding process is best seen in Figures 3 and 4. The laying process is continued in the manner described until finally the number of turns is so high that the opposite first flange 3 with the turns is reached. As soon as this point is reached, the following layers are wound with the same number of turns, which results in parallel layers of wire. This course of the windings is shown schematically by dashed lines 25 running parallel in Figure 3.

Das Wickeln der parallelen Lagen wird solange fortgesetzt, bis der äußerste Rand des zweiten Spulenflansches 4 erreicht ist. Anschließend kann der Wickelvorgang entweder beendet werden, oder er kann fortgesetzt werden, in dem nun eine jeweils verminderte Anzahl von Windungen, praktisch umgekehrt wie am Anfang, aufgebracht werden, so daß das Gebinde eine nach außen zylindrische Form erhält. Das Ende des Drahtes 26 wird dann in wenigen Windungen 49 mit großer Steigung zum Ausgangspunkt des Wickelvorgangs zurückgeführt und liegt dann neben dem Anfang des Drahtes 12.The winding of the parallel layers is continued until the outermost edge of the second coil flange 4 is reached. The winding process can then either be ended or it can be continued by applying a reduced number of turns in each case, practically in reverse to the beginning, so that the container is given an externally cylindrical shape. The end of the wire 26 is then returned in a few turns 49 with a large slope to the starting point of the winding process and then lies next to the start of the wire 12.

Der schematische Aufbaus der Drahtwicklung wird am besten aus Bild 4 ersichtlich. Das Drahtgebinde besteht aus einem inneren Teil 40, welches doppelkonisch geformt ist, d. h., daß es sich nach innen kegelig verengt und nach außen kegelig erweitert. Diese doppelkonische Form bringt den wesentlichen Vorteil mit sich, daß beim Abwickeln, wenn der Draht die inneren, beim Abwickelvorgang immer kritischen Lagen erreicht, sich der Durchmesser der Wicklungen, im aufrechten Zustand des Gebindes, nach unten hin erweitert, gleichgültig, ob nun von innen oder außen abgezogen wird. Auf diese Art und Weise ist es z. B. möglich, Gebinde als Handelsware zu schaffen, die nicht auf die spezifischen Voraussetzungen beim Kunden, ob dort nämlich ein Innen- oder Außenabzug stattfindet, Rücksicht zu nehmen brauchen.The schematic structure of the wire winding is best seen in Figure 4. The wire container consists of an inner part 40, which is double-conical in shape, that is to say it narrows conically inwards and outwards expanded conically. This double-conical shape has the essential advantage that when unwinding, when the wire reaches the inner layers, which are always critical during the unwinding process, the diameter of the windings, when the container is upright, widens downwards, regardless of whether from the inside or is subtracted from the outside. In this way it is e.g. B. possible to create containers as merchandise that do not have to take into account the specific requirements of the customer, whether there is an internal or external deduction.

Neben diesem doppelkonischen Teil 40 ist bei dem dargestellten Ausführungsbeispiel ein parallelverlaufender Teil 42 vorhanden, dessen Durchmesser sich nach unten hin ebenfalls vergrößert. Es wird darauf hingewiesen, daß dieser parallele Teil 42 selbstverständlich auch entfallen kann, es ist ohne weiteres möglich, das Gebinde nur aus dem doppelkonischen Teil aufzubauen.In addition to this double-conical part 40, a parallel part 42 is present in the exemplary embodiment shown, the diameter of which also increases towards the bottom. It is pointed out that this parallel part 42 can of course also be omitted, it is readily possible to assemble the container only from the double-conical part.

An den parallelen Bereichen 42 schließt sich dann der Bereich 43 an, in dem die Lagen so angeordnet sind, daß sich eine zylindrische Außenform der Gebindes ergibt, dieses kann z. B. erreicht werden, in dem der Wickelvorgang, der zur Herstellung des ersten Teiles der Wicklung führte, genau umgedreht wird. Auch dieser Teil der Wicklung kann selbstverständlich entfallen.At the parallel areas 42, the area 43 then follows, in which the layers are arranged in such a way that a cylindrical outer shape of the container results. B. can be achieved in which the winding process that led to the production of the first part of the winding is exactly reversed. This part of the winding can of course also be omitted.

In Bild 5 ist ein versandfertiges Gebinde, welches nach dem erfindungsgemäßen Verfahren erhalten worden ist, dargestellt. Das Gebinde weist eine Papphülle 10 auf, die ihm zusätzliche Stabilität nach innen verleiht. Weiterhin ist eine äußere Hülle 50, z. B. eine Kunststoffolie vorgesehen, die das Gebinde während des Transportes vor Schmutz schützt. Eine zusätzliche Stabilität für den Transport wird durch Umreifungen 51 erzielt, die um das Gebinde herumgelegt sind, wie dies Bild 5 zeigt. Um das Aufbringen dieser Umreifungen zu erleichtern, sind bereits in der Wickelspule entsprechende Kanäle vorgesehen. Weiterhin sind in Umfangsrichtung verlaufende Kunststoffoder Stahlbänder 52 vorgesehen, welche dem Gebinde weiterhin Stabilität verleihen.Figure 5 shows a container ready for dispatch, which has been obtained by the method according to the invention. The container has a cardboard cover 10, which gives it additional stability on the inside. Furthermore, an outer shell 50, for. B. provided a plastic film that protects the container from dirt during transport. Additional stability for transport is achieved by strapping 51, which are placed around the container, as shown in Figure 5. In order to facilitate the application of these strapping, corresponding channels are already provided in the winding spool. Furthermore, are plastic or in the circumferential direction Steel strips 52 are provided, which continue to give the container stability.

Fig. 6 zeigt, wie das Wickelgut von dem Gebinde ohne Verwendung einer Vorrichtung abgezogen werden kann. Dies geschieht, indem das Gebinde aufrecht positioniert wird, so daß der kleinere Durchmesser des Gebindes nach unten weist. Der Draht 56 wird dann, vorzugsweise durch eine hier nicht dargestellte Öse, nach oben abgezogen.Fig. 6 shows how the material to be wound can be removed from the package without using a device. This is done by positioning the container upright so that the smaller diameter of the container points downwards. The wire 56 is then pulled up, preferably through an eyelet, not shown here.

In gleicher Weise ist es auch möglich, das fertige Gebinde innen abzuziehen. Beim Innenabzug wird jedoch, um den Effekt des Doppelkegels richtig auzunutzen, das Gebinde so aufgestellt, daß das Teil mit dem größeren Druchmesser des Gebindes nach unten weist. Es ist also gegenüber der Darstellung in der Fig. 6 um 180° gedreht. Ein solcher Innenabzug ist in Figur 10 gezeigt, wobei hier der Draht 95 aus der Mitte 96 abgezogen wird.In the same way, it is also possible to pull off the finished container on the inside. With the internal trigger, however, in order to take full advantage of the double cone effect, the container is set up so that the part with the larger diameter of the container points downwards. It is rotated by 180 ° compared to the illustration in FIG. 6. Such an internal trigger is shown in FIG. 10, the wire 95 being pulled off the center 96 here.

In Fig. 7 ist dargestellt, wie das Gebinde gemäß Fig. 5 unter Verwendung einer Vorrichtung abgezogen wird. In den Pappkem 10 des Gebindes wird eine Abzungsvorrichtung 60 eingelegt, die aus einem Kern 61 und einer drehbaren Scheibe 62 besteht, welche an ihrem äußeren Umfang eine kreisförmige Leiste 63 trägt. Die Abzugsscheibe 62 ist vorzugsweise drehbar gestaltet. Der Abzug erfolgt dann über diese Scheibe, in dem das strangförmige Gut durch ein in der Achse des Gebindes angeordnete Öse 65, die auf hier nicht dargestellte Weise mit der Abzugsvorrichtung verbunden ist, gezogen wird.FIG. 7 shows how the container according to FIG. 5 is removed using a device. In the cardboard core 10 of the container, a pull-off device 60 is inserted, which consists of a core 61 and a rotatable disk 62, which has a circular strip 63 on its outer circumference. The trigger plate 62 is preferably designed to be rotatable. The take-off then takes place via this disc, in which the strand-like material is drawn through an eyelet 65 arranged in the axis of the container, which is connected to the take-off device in a manner not shown here.

Wie aus Fig. 7 ersichtlich ist, werden die einzelnen Windungen nacheinander abgezogen, wobei jede darauf folgende Windung in diesem Bereich des Gebindes einen größeren Durchmesser aufweist, als die darunterliegende Windung. Dadurch wird ein Verrutschen der Windungen nach unten vermieden, und es kann während des Abzuges, insbesondere bei einem Stillstand des Abzugsvorgangs, nicht zum Verheddern des strangförmigen Gutes kommen.As can be seen from FIG. 7, the individual turns are drawn off one after the other, with each subsequent turn in this area of the container having a larger diameter than the turn underneath. This prevents the windings from slipping downward, and the strand-like material cannot get tangled during the withdrawal, in particular when the withdrawal process is at a standstill.

Es soll nochmal betont werden, daß der Außenabzug des Gebindes die zu bevorzugende Abzugsform bei den nach dem erfindungsgemäßen Verfahren Gebinden ist, es ist selbstverständlich jedoch auch möglich, und liegt ebenfalls im Rahmen der vorliegenden Erfindung, den Draht nach den Bedürfnissen des Kunden von innen abzuziehen.It should be emphasized again that the external withdrawal of the container is the preferred form of withdrawal for the containers according to the method according to the invention, but it is of course also possible and is also within the scope of the present invention to remove the wire from the inside according to the needs of the customer .

In Fig. 8 ist dargestellt, wie zwei nach dem erfindungsgemäßen Verfahren hergestellte Gebinde miteinander verbunden werden, um einen ohne Zeitverlust erfolgenden Übergang von einem ersten Gebinde 70 zu einem zweiten Gebinde 71 zu haben.FIG. 8 shows how two containers produced by the method according to the invention are connected to one another in order to have a transition from a first container 70 to a second container 71 without loss of time.

In Fig. 9 wird gezeigt, wie mehrere der nach dem erfindungsgemäßen Verfahren hergestellten Gebinde für den Transport bereitgestellt werden. Wie ersichtlich, können die Gebinde 90 ohne weitere Hilfsmittel auf einer Palette 91 zum Transport bereitgestellt werden. Um dem Gebinde eine ausreichende Stabilität zu verleihen, sind wiederum, wie bereits beschrieben, Umreifungen 92 vorgesehen.FIG. 9 shows how several of the containers produced by the method according to the invention are made available for transport. As can be seen, the containers 90 can be provided on a pallet 91 for transport without any further aids. In order to give the container sufficient stability, strapping 92 is again provided, as already described.

Bei dieser Methode wird, wie in Fig. 8 gezeigt, das nach außen geführte Ende des Drahtes 12, mit dem ebenfalls nach außen geführten Ende des Drahtes 26 verbunden. Sobald die erste Spule 70 abgewickelt ist, geht der Abwickelvorgang mit dem zweiten Gebinde 71 weiter. In gleicher Weise kann auch ein drittes oder viertes Gebinde angeschlossen werden.In this method, as shown in FIG. 8, the outward end of the wire 12 is connected to the outward end of the wire 26. As soon as the first spool 70 has been unwound, the unwinding process continues with the second container 71. A third or fourth container can also be connected in the same way.

Apparatus for carrying out the method according to at least one of Claims 1 to 11, with a conical winding core (1) provided with flanges, on which a first and a second flange (3,4) are located and a laying device (21), which moves approximately parallel to the axial direction, this laying device being controlled so that at least one first winding layer with a predetermined quantity N₁ of turns is applied to the winding bobbin, which is smaller than the total number Nmax of the quantity of turns to be applied at maximum to the winding bobbin with a given winding pitch, whereupon the laying device is reversed in its direction of movement and the continuous material is wound back to the starting point of the winding process and whereupon further winding layers are applied, which have a quantity of Nx turns, which is respectively greater than the quantity of turns Nx-1 of the preceding layer wound in the same direction, until the maximum number of turns Nmax is reached, characterised in that at the beginning of the winding process, the laying device (21) is located on the side of the winding core (1) with the smallest diameter, that counting devices are provided, which count the quantity of turns Nx , which are wound within one layer on the winding core (1), that a comparator is provided, which produces an output signal, as soon as a predetermined quantity Nx of turns is reached, this signal having the effect that the direction of movement of the laying device is reversed, that an adder is provided, which, as long as the maximum number of turns Nmax is not reached, whenever the laying device (21) reaches its initial position at the smallest diameter of the winding core, adds a constant winding factor Δ N to the last selected quantity of turns Nx and thus fixes the new initial value Nx+1 for the next winding layer.
  21. Apparatus according to Claim 20, characterised in that the counting devices are constructed as pulse counting devices, which receive a predetermined number of pulses at the time of each rotation of the winding bobbin or of the laying device.
  22. Apparatus according to Claim 20 or 21, characterised in that provided in the winding core (1) are channels which are partly open towards the winding, which channels are distributed in the peripheral direction and extend parallel to the surface line of the winding core (1).
  23. Apparatus according to at least one of Claims 20 to 22, characterised in that the axis of the winding core (1) is arranged vertically during the winding process.
  24. Apparatus according to at least one of Claims 20 to 22, characterised in that the axis of the winding core (1) is arranged horizontally during the winding process.
