Description

Die Erfindung betrifft eine Wickelspule, bestehend aus einem hohlen Spulenkern und zwei Flanschen, von denen mindestens einer lösbar mit dem Spulenkern mittels eines Bajonettverschlusses verbunden ist, dessen zusammenwirkende Rast- und Halteelemente jeweils an dem betroffenen Spulenkernende und an der Flanschinnenwand vorspringend so auf Lücke angeordnet sind, daß der lösbare Flansch und das Spulenkernende ineinandersetzbar und durch Verdrehen der Bajonettverschluß in durch Anschlag begrenzte Schließlage bringbar ist.The invention relates to a winding coil, consisting of a hollow coil core and two flanges, at least one of which is detachable from the coil core by means of a Bayonet lock is connected, the cooperating locking and holding elements protruding at the respective coil core end and on the inner wall of the flange are arranged so that the detachable flange and the coil core end interlocking and by twisting the bayonet lock in by stop limited closed position can be brought.

Derartige Wickelspulen werden mit Materialien aller Art, insbesondere auch Drähten, Seilen, Kabeln und dergleichen, bewickelt. Sie sind in ihrem Grundaufbau langjährig bekannt. Die lösbare Anbringung mindestens einer der Flansche am Spulenkern bringt in Verbindung mit konischen oder zerlegbaren Spulenkernen Raumvorteile beim Leertransport derartiger Wickelspulen insbesondere beim Rücktransport der Wickelspulen vom Verbraucher des Wickelgutes zurück zum Bewickler. Such winding spools are made with materials of all kinds, in particular also wires, Ropes, cables and the like, wound. In their basic structure they are long standing known. The releasable attachment of at least one of the flanges to the coil core brings in connection with conical or demountable coil cores, space advantages for empty transport such winding coils especially when the winding coils are returned from the consumer of the winding material back to the winder.

Wickelspulen der in Frage stehenden Art sind beispielsweise aus WO 9413569, WO 9413570, EP 0 411 978 oder DE 79 35 978 U1 bekannt.Winding spools of the type in question are known, for example, from WO 9413569, WO 9413570, EP 0 411 978 or DE 79 35 978 U1.

Aus dem DE 298 06 519 U1 ist eine gattungsgemäße Wickelspule bekannt, bei der auf mindestens einem der Bajonettverschlußelemente ein Rastnocken angeformt ist, für den in dem anderen, damit zusammenwirkenden Bajonettverschlußelement eine Rastausnehmung vorgesehen ist.From DE 298 06 519 U1 a generic winding spool is known in which at least one of the bayonet locking elements is formed with a locking cam for the one in the other, interacting bayonet locking element with a locking recess is provided.

Aus DE 91 13 247.9 U1 ist eine Wickelspule bekannt, bei der ein lösbarer Flansch über eine Raststeckverbindung in den hohlen Wickelkern der Spule eingesteckt werden kann. Zur zusätzlichen Verriegelung ist im Überdeckungsbereich zwischen Wikkelkern und Steckvorsprung des Flansches ein Stopfen durch den Wickelkern hindurch einsetzbar. Das Einsetzen erfolgt vor der Bewicklung der Spule. Der Stopfen wird nach der Bewicklung von dieser überdeckt.From DE 91 13 247.9 U1 a winding spool is known in which a detachable flange be inserted into the hollow winding core of the coil via a snap-in connector can. For additional locking is in the overlap area between the winding core and plug-in projection of the flange a plug through the winding core used. It is inserted before the coil is wound. The stopper will covered by this after wrapping.

Da bei bestimmen Anwendungsfällen der Wunsch besteht, insbesondere wenn in der Be- und Abwickelphase plötzliche Beschleunigungen oder Abbremsungen erfolgen müssen, ein Verdrehen von Flansch und Spulenkern in Löserichtung des Bajonettes zusätzlich durch einen Verriegelungsmechanismus zeitweise zu blockieren, sind verschiedene Ausführungsformen bekannt geworden, bei denen im Flansch oder am Wikkelkern Verriegelungselemente integriert sind, die in die Lücke des Bajonettverschlusses, also beispielsweise zwischen zwei Rast- oder zwei Halteelemente eingreifen können und die beim Ineinandersetzen von Flansch- und Spulenkernende federnd zurückgedrängt werden und nach Überführung des Bajonettverschlusses in seine Schließlage wieder in die Lücken zurückfedern und damit den Bajonettverschluß gegen Aufdrehen sichern.Since there is a desire for certain applications, especially if in the Sudden accelerations or decelerations occur during the unwinding and unwinding phases a twisting of the flange and coil core in the release direction of the bayonet to block temporarily by a locking mechanism are different Embodiments have become known in which in the flange or on the winding core Locking elements are integrated, which are in the gap of the bayonet lock, So can intervene, for example, between two locking or two holding elements and which is resiliently pushed back when the flange and coil core ends are nested and after transferring the bayonet lock into its closed position spring back into the gaps and thus the bayonet lock against unscrewing to back up.

Derartige Verriegelungselemente sind kompliziert und teuer sowohl bezüglich ihrer Herstellung wie teilweise auch bezüglich ihrer Montage im Flansch und werden bei zahlreichen Anwendungsfällen für derartige Wickelspulen, bei denen die Sicherung von Flansch und Spulenkern in axialer Richtung der Wickelspule durch den Bejonettverschluß völlig ausreicht, nicht benötigt.Such locking elements are complicated and expensive in terms of both Manufacture as in part also with regard to their assembly in the flange and are at numerous applications for such winding spools, in which the fuse flange and spool core in the axial direction of the winding spool through the Bejonett lock completely sufficient, not needed.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, eine Wickelspule der gattungsgemäßen Art zu schaffen, die bei denkbar einfachem konstruktiven Aufbau universell einsetzbar ist.The present invention is therefore based on the object of a winding spool of the generic type to create that with a very simple structural design is universally applicable.

Die erfindungsgemäße Lösung besteht bei einer Wickelspule der gattungsgemäßen Art im wesentlichen darin, daß zusammenwirkende Rast- und Halteelemente mit in der Schließlage des Bajonettverschlusses fluchtend liegenden Durchbrechungen versehen sind, in die in Achsrichtung der Wickelspule ein Steckzapfen einsteckbar ist. The solution according to the invention consists in a winding spool of the generic type essentially in that cooperating locking and holding elements in the Provide the openings of the bayonet catch in the closed position in alignment are, in which a plug pin can be inserted in the axial direction of the winding spool.

Eine derartige Wickelspule hat einen außerordentlich einfachen konstruktiven Aufbau, da der Steckzapfen ein sehr einfach herzustellendes Bauteil ist und auch das Vorsehen der Bohrungen in den Rast- und Halteelementen problemlos fertigungstechnisch zu bewerkstelligen ist. Die Wickelspule ist universell einsetzbar. Die Steckzapfen zur Sicherung des Bajonettverschlusses gegen unzeitiges Aufdrehen werden nur dann benötigt und eingesteckt, wenn der Anwendungsfall das zweckmäßig erscheinen läßt.Such a winding spool has an extremely simple constructive Construction, because the plug is a very easy to manufacture component and also the provision of the holes in the locking and holding elements easily in terms of production technology is to be accomplished. The winding spool can be used universally. The plug pins to secure the bayonet catch against untimely unscrewing are only needed and plugged in if the application is makes seem appropriate.

Weitere bevorzugte Ausgestaltungen insbesondere bezüglich der Ausgestaltung des Steckzapfens und der Möglichkeiten zu seiner Entnahme ergeben sich aus Unteransprüchen.Further preferred configurations, in particular with regard to the configuration the plug and the possibilities for its removal result from Dependent claims.

Die Wickelspule besteht in ihrem Grundaufbau aus einem Spulenkern 1, auf dem das Wickelgut aufgewickelt wird. Der Spulenkern 1 ist seitlich durch zwei scheibenartige Flansche 2 und 3 begrenzt. Wie in Figur 1 illustriert, ist zumindest einer der Flansche lösbar mit dem entsprechenden Ende des Spulenkernes 1 verbunden. Im dargestellten Ausführungsbeispiel ist der Spulenkern 1, der hohl ausgebildet ist, konisch ausgestaltet. Der Flansch 2 am Spulenkern mit dem größeren Durchmesser ist einstückig mit dem Spulenkern ausgebildet, während der für das im Durchmesser kleinere Spulenkernende vorgesehene Flansch 3 mit diesem Ende lösbar zu verbinden ist. Die Flansche 2, 3 sind in der üblichen Weise durch radial verlaufende Rippen und konzentrisch zum Zentrum verlaufende ringförmige Stege verstärkt.In its basic structure, the winding coil consists of a coil core 1 on which the material to be wound is wound up. The coil core 1 is laterally by two disk-like Flanges 2 and 3 limited. As illustrated in Figure 1, at least one is the flanges releasably connected to the corresponding end of the coil core 1. In the illustrated embodiment, the coil core 1 is hollow is conical. The flange 2 on the coil core with the larger diameter is formed in one piece with the coil core, while for the in Diameter smaller coil core end provided flange 3 with this end is releasably connected. The flanges 2, 3 are radial in the usual way running ribs and annular webs concentric to the center strengthened.

Abweichend vom dargestellten Ausführungsbeispiel können beide Flansche lösbar mit dem Spulenkern verbunden sein. Der Spulenkern kann in bekannter Weise auch zylindrisch sowie auch in der Grundform zylindrisch sowie zerlegbar ausgebildet sein.Deviating from the illustrated embodiment, both flanges can be detached be connected to the coil core. The coil core can in a known manner also cylindrical and also cylindrical in its basic form and can be dismantled his.

Für die lösbare Verbindung zwischen dem lösbaren Flansch 3 und dem betroffenen Ende des Spulenkernes 1 ist ein Bajonettverschluß vorgesehen. Hierfür sind am betroffenen Ende des Spulenkernes 1 abständig am Innenumfang verteilt Halteelemente 4 ausgebildet. Die nach innen in den hohlen Spulenkern 1 vor springenden Halteelemente sind dabei jeweils an ihrem einen Ende über Stege 6 an den betroffenen Endbereichen der Wandung 5 des Spulenkernes angeformt. Im dargestellten Ausführungsbeispiel tragen die Stege 6 einen Ringkörper 7, in den die Halteelemente 4 übergehen. Der im Außendurchmesser gegenüber dem Durchmesser des hier betroffenen Endes des Spulenkernes 1 kleinere Ringkörper definiert mit seinem Innenwandabschnitt eine Aufnahme 8 für die Wickelwelle einer Auf- oder Abwickelvorrichtung, dergestalt, daß über diese zumindest in Teilbereichen konisch ausgebildete Aufnahme 8 die Abwickel- und Aufwickelkräfte direkt zentrisch auf den Spulenkern 1 der Wickelspule aufgebracht werden können, insbesondere also nicht über den lösbaren Flansch 3 und damit den Bejonettverschluß übertragen werden müssen. For the detachable connection between the detachable flange 3 and the affected A bayonet lock is provided at the end of the coil core 1. For this are at the affected end of the coil core 1 spaced apart on the inner circumference holding elements 4 trained. The jumping inwards in the hollow coil core 1 before Holding elements are each at one end via webs 6 to the Affected end regions of the wall 5 of the coil core. In the illustrated Embodiment, the webs 6 carry an annular body 7, in which the Skip holding elements 4. The outside diameter compared to the diameter of the end of the coil core affected here defines 1 smaller ring body with its inner wall section a receptacle 8 for the winding shaft one Winding or unwinding device, such that this at least in some areas conically shaped receptacle 8 the unwinding and winding forces directly can be applied centrally to the coil core 1 of the winding coil, in particular So not on the detachable flange 3 and thus the Bejonett lock must be transferred.

Wie aus den Figuren ersichtlich, bilden die abständigen Halteelemente 4 im Umfangsverlauf gesehen zwischen sich Lücken 9. An dem lösbaren Flansch sind nun am Umfang verteilt ebenfalls untereinander abständige Rastelemente 10 vorgesehen. Diese springen von der Innenwand 11 des scheibenringförmigen Flansches 3 nach innen vor. Im Sinne eines Bajonettverschlusses ist die Anordnung so getroffen, daß für die Montage von lösbarem Flansch und Spulenkern der Flansch mit seinen Rastelementen 10 auf das betroffene Ende des Spulenkernes 1 derart gesetzt werden kann, daß die Rastelemente 10 in die Lücke 9 zwischen den Halteelementen eintreten können, und zwar so weit, daß sie durch Verdrehen des Flansches 3 in Schließrichtung des Bejonettverschlusses unter die Halteelemente 4 treten können, wobei die Stege 6 der Halteelemente 4 dann für die Schließstellungsdrehlage Anschläge bilden und damit die Schließlage des Bajonettverschlusses auch definieren. In der Schließlage sind damit in Achsrichtung der Wickelspule gesehen der Spulenkern 1 und der lösbare Flansch fest miteinander verbunden.As can be seen from the figures, the spaced holding elements 4 form in the circumferential course seen gaps between them 9. Now on the detachable flange spaced locking elements 10 are also distributed around the circumference. These jump from the inner wall 11 of the disk-shaped flange 3 inside in front. In the sense of a bayonet lock, the arrangement is made so that for the assembly of detachable flange and coil core of the flange its locking elements 10 placed on the affected end of the coil core 1 in this way can be that the locking elements 10 in the gap 9 between the holding elements can occur, and so far that they can be twisted by the flange 3 in the closing direction of the Bejonett lock under the holding elements 4 can occur, the webs 6 of the holding elements 4 then for the closed position rotational position Form stops and thus the closed position of the bayonet catch also define. In the closed position are thus in the axial direction of the winding spool seen the coil core 1 and the releasable flange firmly connected.

Um diese für zahlreiche Anwendungsfälle ausreichende Sicherung von Spulenkern und lösbarem Flansch auch für Anwendungsfälle geeignet zu machen, in denen eine zusätzliche Sicherung des Bajonettverschlusses in der Schließlage gegen ein unzeitiges Aufdrehen in Löserichtung eingesetzt werden soll, ist nunmehr vorgesehen, daß zusammenwirkende Rast- und Halteelemente 4, 10 mit Durchbrechungen versehen sind, die in der Schließlage des Bajonettverschlusses fluchtend zueinander liegen und in die in der Schließstellung des Bajobettverschlusses in Achsrichtung der Wickelspule gesehen ein Steckzapfen 12 eingesteckt werden kann. Im dargestellten Ausführungsbeispiel tragen alle Rastelemente 10 des lösbaren Flansches 3 als Durchbrechung eine Bohrung 13. Dies gewährleistet, daß man den Flansch in beliebiger Lage in den Spulenkern einsetzen kann. von der Unterseite des Halteelementes 4 her auf dem Boden einer Einsenkung 15 in der Oberfläche des Halteelementes 4 und bildet einen weiteren Teil der Durchbrechung im Halteelement 4.To ensure that the coil core is adequately secured for numerous applications and detachable flange also suitable for applications in which an additional securing of the bayonet lock in the closed position against untightened unscrewing in the release direction is now provided, that cooperating locking and holding elements 4, 10 with openings are provided, which are in alignment with one another in the closed position of the bayonet catch and in the closed position of the bayonet lock in the axial direction seen the winding spool, a plug 12 can be inserted. in the illustrated embodiment carry all locking elements 10 of the releasable flange 3 a hole 13 as an opening. This ensures that the Can insert flange in any position in the coil core. from the underside of the holding element 4 on the bottom of a depression 15 in the surface of the holding element 4 and forms a further part of the opening in the holding element 4.
