Description

Die Erfindung betrifft einen Spulenkörper, insbesondere eine Bobine für die Aufnahme wenigstens eines auf- bzw. von dieser abwickelbaren Längselementes, mit einer Trommel und beidseitig je einem Wandungselement.The invention relates to a coil former, in particular a bobbin for receiving at least one longitudinal element that can be wound up or unwound from the latter, with a drum and a wall element on each side.

Solche Spulenkörper und insbesondere Bobinen sind allgemein bekannt. Diese eignen sich für das Aufwickeln allem voran von schweren Seilen und Elektrokabeln und sind daher beispielsweise mit einem Trommeldurchmesser von 2.6 Metern und aussen bei den runden Wandungselementen mit einem solchen von 4.6 Metern dimensioniert. Damit können diese Bobinen ein Eigengewicht von mehr als 4'000 kg aufweisen. Wenn die Seile bzw. Elektrokabel nach dem Verlegen von diesen Bobinen abgewickelt sind, werden letztere zum Beispiel von dem Verlegeort wieder zurück zum Herstellungsort transportiert und dort wird folglich wieder ein gefertigtes Seil oder Kabel aufgewickelt. Auch beim Transportieren dieser Bobinen im Leerzustand müssen sie aufgrund ihrer Dimensionen bzw. ihres Gewichtes als separate Fracht auf Schiffen oder Lastkraftfahrzeugen geladen werden, was die Transportkosten nicht unerheblich verteuert.Such bobbins and in particular bobbins are well known. These are particularly suitable for winding up heavy ropes and electric cables and are therefore dimensioned, for example, with a drum diameter of 2.6 meters and on the outside with a diameter of 4.6 meters for the round wall elements. This means that these bobbins can weigh more than 4,000 kg. When the ropes or electric cables are unwound from these bobbins after being laid, the latter are transported, for example, from the laying location back to the place of manufacture, and a finished rope or cable is consequently wound up there again. Even when transporting these bobbins when empty, they must be loaded as separate cargo on ships or trucks due to their dimensions and weight, which increases the transport costs not insignificantly.

In der Druckschrift US 1,905,488 ist eine Trommel mit einem Ring und beidseitig zu diesem je eine Wand aus je 8 Sektionen offenbart, die jeweils aus einem Rahmen und einem verstärkenden Profil mit je radialen Öffnungen zusammengesetzt sind. Diese Rahmen sind zudem aussenseitig mit Öffnungen für das Befestigen von Streben als Verschalung versehen. Diese verstärkenden Profile werden innerhalb der Rahmen eingesetzt bzw. von diesen im gelösten Zustand weggenommen. Diese mehreren Komponenten, namentlich der Ring, der Flansch, diese Profile und die Rahmen müssen genau aufeinander abgestimmt sein, damit diese zusammengeschraubt werden können. Zudem werden aussenseitig bei den Rahmen diese die Verschalung bildenden Streben befestigt.In the pamphlet U.S. 1,905,488 discloses a drum with a ring and, on both sides of this, a wall each consisting of 8 sections, each of which is composed of a frame and a reinforcing profile, each with radial openings. These frames also have openings on the outside for attaching struts as cladding. These reinforcing profiles are inserted inside the frames or removed from them in the released state. These several components, namely the ring, the flange, these profiles and the frames must be precisely matched so that they can be screwed together. In addition, these struts forming the formwork are fastened to the outside of the frame.

Gemäss der Druckschrift WO 2005/047156 ist eine Spulenvorrichtung offenbart, bei der zylindrische Segmente mit Endscheiben verbunden werden. Die Segmente sind dabei durch schwalbenschwanzförmige Verbindungsmittel aneinander befestigt, währenddem sie mit den seitlichen Endscheiben durch Haken und Verschlüsse verbunden sind. Es sind ausserdem separierte Komponenten als Scheibensegmente und dreieckförmige Scheibenelemente vorgesehen. Zudem sind ausserhalb der Endscheiben radförmig angeordnete, sich radial erstreckende Streben mit einem innen- und aussenseitigen Ring vorhanden, wobei letzterer auf Rädern abgestützt ist und auf diesen ein Drehen der Spule erfolgen kann.According to the pamphlet WO 2005/047156 a coil device is disclosed in which cylindrical segments are connected to end discs. The segments are connected by dovetail-shaped connecting means attached to each other while being connected to the side end plates by hooks and clasps. Separate components are also provided as disc segments and triangular disc elements. In addition, outside of the end disks there are radially extending struts arranged in the shape of a wheel with an inner and outer ring, the latter being supported on wheels and on which the spool can be rotated.

Der Erfindung liegt die Aufgabe zugrunde, einen Spulenkörper nach der eingangs erwähnten Gattung zu schaffen, durch welchen der Leertransport vereinfacht und somit kostengünstiger ausgeführt werden kann.The invention is based on the object of creating a bobbin of the type mentioned at the outset, through which empty transport can be simplified and thus carried out more cost-effectively.

Diese Aufgabe ist erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the features of claim 1 .

Die Trommel und die beiden Wandungselemente des Spulenkörpers jeweils aus mehreren zusammengesetzten Segmenten auszubilden, ermöglicht, dass der Spulenkörper insbesondere für den Leertransport zerlegt und beim Herstellungsort der Längselemente wieder einfach zusammenmontiert und für die nächste Beladung vorbereitet werden kann. Damit können die Aufwendungen und die Kosten den Transportgegebenheiten angepasst bzw. optimiert werden.Forming the drum and the two wall elements of the bobbin each from several assembled segments allows the bobbin to be dismantled, in particular for empty transport, and easily reassembled at the production site of the longitudinal elements and prepared for the next loading. In this way, the expenses and costs can be adapted or optimized to the transport conditions.

Es sind bei den Verbindungsstellen der Segmente jeweils ein oder mehrere Auflager zugeordnet, bei denen die Segmente durch Befestigungsmittel aneinander lösbar befestigt werden können und ausserdem gegenseitig lagepositioniert sind, wodurch der Zusammenbau zu einer einsatzbereiten Bobine schnell und rationell erfolgen kann.At the connection points of the segments, one or more supports are assigned, in which the segments can be releasably attached to one another by fastening means and are also mutually positioned, whereby assembly into a ready-to-use bobbin can be carried out quickly and efficiently.

Solche erfindungsgemässe Spulenkörper eignen sich besonders für das Aufwickeln von Stahlseilen, Elektrokabeln, Hanfseilen oder dergleichen, bei denen der Aussendurchmesser der Wandungselemente mehrere Meter betragen.Such bobbins according to the invention are particularly suitable for winding up steel cables, electric cables, hemp cables or the like, in which the outer diameter of the wall elements is several meters.

Zweckmässigerweise sind die Trommel und auch die Wandungselemente jeweils in vier bis acht Segmente unterteilt, welche dabei derart dimensioniert sind, dass sie den Abmessungen eines normierten Frachtcontainers angepasst sind, wobei Segmente von mehreren Spulenkörpern in einen Frachtcontainer ladbar sind.The drum and also the wall elements are expediently divided into four to eight segments, which are dimensioned in such a way that they are adapted to the dimensions of a standardized freight container, with segments from a number of coil formers being loadable into a freight container.

Fig. 1 zeigt einen Spulenkörper im demontierten und Fig. 2 denselben im montierten Zustand, bei dem es sich insbesondere um eine Bobine 10 für die Aufnahme wenigstens eines auf- bzw. abwickelbaren Längselementes handelt, das nicht näher dargestellt ist. Auf eine solche Bobine 10 kann wenigstens ein Stahlseil, ein Elektrokabel jeglicher Art, ein Hanfseil oder dergleichen aufgewickelt, transportiert und an einem Verlegeort wieder abgewickelt werden. Diese Bobine 10 ist üblicherweise mit Dimensionen von zwei bis sechs Metern Aussendurchmesser und einer Breite von einem bis sechs Metern versehen. 1 shows a bobbin in disassembled and 2 the same in the assembled state, which is, in particular, a bobbin 10 for receiving at least one longitudinal element that can be wound up or unwound, which is not shown in detail. On such a bobbin 10 At least one steel cable, an electric cable of any kind, a hemp cable or the like can be wound up, transported and unwound again at a laying location. This bobbin 10 is usually provided with dimensions of two to six meters outside diameter and a width of one to six meters.

Die Bobine 10 besteht aus einer Trommel 15 und beidseitig je einem abschliessenden Wandungselement 11, 12. Im Prinzip könnte im Mittenbereich der Trommel 15 auch wenigstens ein drittes Wandungselement vorgesehen sein, wenn zum Beispiel zwei verschiedene Längselemente aufgewickelt werden sollen. Diese Wandungselemente 11, 12 sind scheibenförmig ausgebildet und gestatten damit ein Rollen der Bobine.The bobbin 10 consists of a drum 15 and a closing wall element 11, 12 on each side. In principle, at least a third wall element could also be provided in the central area of the drum 15 if, for example, two different longitudinal elements are to be wound up. These wall elements 11, 12 are disk-shaped and thus allow the bobbin to roll.

Ausserdem ist in der Trommel 15 eine durchgehende zentrale Achse 14 enthalten, welche zumindest an beiden Enden in je einer Nabe 18 eines vorzugsweise radförmigen Kranzes 17 gelagert ist. Zweckmässigerweise ist diese Achse 14 hohl ausgebildet, damit durch diese eine Welle einführbar ist, welche beidseitig auf einem Lagerbock oder dergleichen stellbar ist, damit die Bobine für das Auf- bzw. Abwickeln des Längselementes darauf gedreht werden kann.In addition, the drum 15 contains a continuous central axle 14 which is mounted at least at both ends in a respective hub 18 of a preferably wheel-shaped rim 17 . This axle 14 is expediently hollow, so that a shaft can be inserted through it, which can be adjusted on both sides on a bearing block or the like, so that the bobbin can be rotated on it for winding or unwinding the longitudinal element.

Erfindungsgemäss ist die Trommel 15 aus mehreren aneinander verbindbaren teilzylinderförmigen Segmenten 15' und die beiden Wandungselemente 11, 12 jeweils aus mehreren aneinander befestigbaren Segmenten 11', 12' zusammengesetzt, wobei letztere ähnlich einem Trapez gebildet sind und im montierten Zustand diese Scheibenform bilden.According to the invention, the drum 15 is composed of several partially cylindrical segments 15' that can be connected to one another and the two wall elements 11, 12 are each composed of several segments 11', 12' that can be fastened to one another, the latter being formed like a trapezoid and forming this disc shape when assembled.

Beim Ausführungsbeispiel dieser Bobine 10 sind je sechs Segmente 15`, 11', 12' bei der Trommel 15 bzw. den jeweiligen Wandungselementen 11, 12 vorgesehen. Selbstverständlich könnte je nach Grösse des Spulenkörpers und den vorhandenen Bedürfnissen auch eine andere Anzahl von diesen Segmenten gewählt werden, vorzugsweise sind aber zwischen vier bis acht vorteilhaft.In the exemplary embodiment of this bobbin 10, six segments 15', 11', 12' are provided for the drum 15 and the respective wall elements 11, 12 provided. A different number of these segments could of course also be selected depending on the size of the coil body and the existing requirements, but preferably between four and eight are advantageous.

Den Segmenten 15' der Trommel 15 sind bei den Verbindungsstellen jeweils mehrere Auflager 18, 19 zugeordnet, durch welche dieselben mit den benachbarten Segmenten 15' durch Befestigungsmittel aneinander lösbar befestigt und gegenseitig lagepositioniert sind. Es sind einerseits mehrere über die Länge des jeweiligen Segmentes 15' verteilt vorstehende Auflager 18 und andererseits auf der gegenüberliegenden Längsseite mehrere korrespondierende innenseitige Auflager 19 angeordnet. Die Auflager 18 bilden dabei eine Auflagefläche für das anschliessende Segment, so dass diese nach dem Verbinden gegenseitig ausgerichtet sind und ihre Stosskanten 15" aneinanderliegen.The segments 15' of the drum 15 are each assigned a plurality of supports 18, 19 at the connection points, by means of which they are detachably fastened to one another with the adjacent segments 15' by means of fastening means and are mutually positioned. On the one hand there are several protruding supports 18 distributed over the length of the respective segment 15 ′ and on the other hand several corresponding inner supports 19 are arranged on the opposite longitudinal side. The supports 18 form a support surface for the adjoining segment, so that they are mutually aligned after the connection and their abutting edges 15" are in contact with one another.

Als Befestigungsmittel werden vorteilhaft Schrauben 20 verwendet, welche von innen in diese Auflager 18, 19 einschraubbar sind. Die innenseitigen Auflager 19 sind mit Sacklöchern versehen, so dass die Segmente 15' aussenseitig keine Löcher aufweisen und spielfrei aneinanderstossen, wie gemäss Fig. 2 ersichtlich ist. Damit liegen die Längselemente, zum Beispiel Elektrokabel, nach dem Aufwickeln auf stossfreien Flächen auf, nicht dass Eindrücke bei der Aussenisolation der Kabel entstehen könnten.Screws 20, which can be screwed into these supports 18, 19 from the inside, are advantageously used as fastening means. The supports 19 on the inside are provided with blind holes, so that the segments 15' have no holes on the outside and abut one another without play, as shown in FIG 2 is evident. This means that the longitudinal elements, for example electric cables, lie on smooth surfaces after they have been wound up, preventing impressions from forming on the outer insulation of the cables.

Bei der Montage der Trommel 15 können diese Segmente 15' mit Vorteil aufgestellt und spielfrei aneinander geschoben und anschliessend zusammengeschraubt werden, wobei die Schrauben maschinell eingeschraubt werden können, so dass dies speditiv ausgeführt werden kann.When assembling the drum 15, these segments 15' can advantageously be set up and pushed against one another without play and then screwed together, the screws being able to be screwed in by machine so that this can be carried out expeditiously.

Bei den Verbindungsstellen der Wandungselemente 11, 12 sind den Segmenten 11', 12' jeweils ein längliches Auflager 21, 22 zugeordnet, welches mit einem Auflager 23, 24 als Auflagefläche aussenseitig bei den Segmenten 11', 12' korrespondiert. Durch Befestigungsmittel sind die Segmente bei den Auflagern aneinander befestigbar, so dass sie nach dem Verbinden gegenseitig ausgerichtet sind und ihre Stosskanten 11", 12" ebenso innenseitig spielfrei aneinanderliegen. Die Schrauben 20 sind in diese Auflager 21, 22 einschraubbar, wobei die innenseitigen Auflager ebenfalls mit Sacklöchern ausgebildet sind, so dass die Segmente innenseitig keine Löcher aufweisen und spielfrei aneinanderstossen, wie dies in Fig. 2 veranschaulicht ist.At the connection points of the wall elements 11, 12, the segments 11', 12' are each assigned an elongated support 21, 22, which corresponds to a bearing 23, 24 as a bearing surface on the outside of the segments 11', 12'. The segments can be fastened to one another at the supports by means of fastening means, so that after connection they are mutually aligned and their abutting edges 11", 12" also lie against one another on the inside without play. The screws 20 can be screwed into these supports 21, 22, with the supports on the inside also being designed with blind holes, so that the segments have no holes on the inside and abut without play, as is shown in 2 is illustrated.

Zusätzlich weisen die Segmente 11', 12' innen je wenigstens ein Auflager 24, 25 auf, welches mit einem korrespondierenden Auflager 27, 28 am Aussenumfang eines jeweiligen Segmentes 15' der Trommel 15 durch Befestigungsmittel verbindbar ist. Es ist dabei vorgesehen, dass die beiden die Achse 14 lagernden Kränze 17 gleichsam mit denselben Schrauben 20 innenseitig der Trommel 15 befestigt wird.In addition, the segments 11′, 12′ each have at least one support 24, 25 on the inside, which can be connected to a corresponding support 27, 28 on the outer circumference of a respective segment 15′ of the drum 15 by fastening means. It is provided that the two rims 17 supporting the axle 14 are fastened with the same screws 20 on the inside of the drum 15 .
