Description

liegend gelagerter Wickeldorn mit aiaier~Sehulterfläche Die Erfindung betrifft einen fliegend geligertell Wickeldorn mit einer axial gerichteten Schulterfläche und keilwellenähnlich pngeordneten radialen Nocken zur Aufnahme eines mit korrespondierenden Nocken versehenen Wickelkerus..horizontally mounted winding mandrel with normal shoulder surface. The invention relates to a flying geligertell mandrel with an axially directed shoulder surface and radial cams arranged similarly to splines to accommodate a corresponding one Cam provided winding core ..

Dernrtige Wickeldorne dienen beispielsweise der Auf'nPhme von Wickelkernen, wie sie in Tonbandkassetten verwendet werden, zum Aufwickeln von Magnettonbandabschnitten.The winding mandrels are used, for example, to accommodate winding cores, as used in tape cassettes, for winding magnetic tape sections.

Bisher bekannte Wickeldorne haben Nocken, deren Flanken achsparalle verlaufen. Auf diesen Wickeldornen können sich die Wickelkerne in axialer Richtung verschieben und bei fliegend gelagerten Wickeldornen von diesen abgleiten. Selbst geringe nsiale Verschiebungen machen es aber schon unmöglich, kantengleiche Wickel herzustellen. Um axiale Verschiebungen der Wickelkerne oder gar deren Abgleiten von einem Wickeldorn zu unterbinden, ist es bekannt, an dem Wickeldorn zusätzliche Haltemittel vorzusehen, die den Wickelkern an die Schulterfläche anlegen sollen, so daß sich an dieser die Kante oder der Saum eines aufzuwickelnden Bandes ausrichten kann. Diese Ausbildung ist nicht nur konstruktiv recht aufwendig, sondern von gewichtigem Nachteil beim Herstellen großer Zahlen von Wickeln, weil zu jedem Abnehmen eines bewickelten Wickelkernes zwei Hände benutzt werden müssen.Previously known winding mandrels have cams whose flanks are axially parallel get lost. On these mandrels, the winding cores can be in the axial direction move and slide off these with cantilevered mandrels. Self However, slight nsial shifts make it impossible to create coiled wraps to manufacture. About axial displacements of the winding cores or even their sliding off To prevent a winding mandrel, it is known to add additional to the winding mandrel To provide holding means, which should place the winding core on the shoulder surface, so that the edge or the hem of a tape to be wound is aligned with this can. This training is not only very complex in terms of construction, but also weighty Disadvantage when producing large numbers of diapers, because one for each weight loss wound core must be used two hands.

Mit einer Hand muß der Wickel gehalten werden, die andere muß das Ilaltemittel lösen Eine Hand wird aber bereits für andere handgriffe benötigt, so zwn Aus- oder Einschalten des Antriebs des Wickeldornes, zum Trennen des Bandes und sonstigen anderen Bedienungsgriffen.The wrap must be held with one hand, the other must Solving old substances One hand is already required for other hand movements, see above zwn switching off or on the drive of the winding mandrel to separate the belt and other other operating handles.

Der Erfindung liegt die Aufgabe zugrunde, einen fliegend gelagerten Wickeldorn bereitzustellen, der eine möglichst einfurche Bedienung gestattet, zugleich aber auch keinen besonderen konstruktiven Aufwand erfordert. ei einem eingangs beschriebenen Wickeldorn ist diese Aufgabe nuf überraschend einfache Weise gemäß der Erfindung dadurch gelöst, dß die in Drehrichtung weisenden Flanken der Nocken des Wickeldornes in Richtung zu der Schulterfläche hinterschnitten ausgebildet sind. Diese Ausbildung gestattet es, den Wickelkern bei Stillstand des Wickeldornes leicht suf diesen sufsetzen zu können. Sowie aber der Wickeldorn angetrieben wird, bewirken die hinterschnittenen Flanken ein Anpressen des Wickelkernes auf dem Wickeldorn in Richtung auf die axial gerichtete Schulterfläche. Zum Aufstecken des Wickelkernes auf den Wickeldorn und zum Abnehmen des bewickelten Wickelkernes wird somit nur noch eine Hand benötigt. Die andere Hand ist für alle anderen Handgriffe frei, so daß zugleich kürzere Stückzeiten erzielt werden können.The invention is based on the object of a cantilevered Provide winding mandrel that allows an operation that is as furrowed as possible, at the same time but also does not require any special design effort. ei one described at the beginning Winding mandrel this task is in a surprisingly simple manner according to the invention solved by the fact that the flanks of the cams of the winding mandrel pointing in the direction of rotation are formed undercut in the direction of the shoulder surface. This training allows the winding core to be easily sufetzen when the winding mandrel is at a standstill to be able to. But as soon as the winding mandrel is driven, the undercut Flanks a pressing of the winding core on the winding mandrel in the direction of the axial directed shoulder surface. For attaching the winding core to the winding mandrel and only one hand is needed to remove the wound core. The other hand is free for all other hand movements, so that at the same time shorter piece times can be achieved.

In der Zeichnung ist die Erfindung beispielsweise und schematisch dargestellt. Es zeigen: Fig. 1 einen Wickeldorn iii einer Seitenansicht, und Fig. 2 den Wickeldorn in der DrsulW sicht.In the drawing, the invention is exemplified and schematic shown. 1 shows a winding mandrel in a side view, and FIG. 2 the winding mandrel in the DrsulW view.

Nach der Zeichnung ist ein fliegend gelagerter Wickeldorn aus einem eigentlichen Wickeldorn (l) mit keilwellenähnlich angeordneten radialen Nocken (all) mittels einer Schraube (2) zusammengesetzt mit Scheibe (3), die eine r'xial gerichtete Schulterfläche (31) und einen und (32) zeigt.According to the drawing, an overhung winding mandrel is made of one actual winding mandrel (l) with radial cams (all) arranged like a spline assembled by means of a screw (2) with washer (3), which has a r'xially directed Shows shoulder surface (31) and one and (32).

Der Wickeldorn (i) in Verbindung mit der Schulterfläche (31) ist zur Aufnahme eines - in Striohpunktlinie dargestellten -Wickelkernes (4) vorgesehen, der zu den Nocken (11) korrespondierende Nocken (41) aufweist. Der Bund (32) greift in eine Aussparung (42) des Wickelkerns (4).The winding mandrel (i) in connection with the shoulder surface (31) is for Recording of a winding core (4) - shown in a dash-dotted line - provided, the one corresponding to the cam (11) Has cams (41). The collar (32) engages in a recess (42) in the winding core (4).

Auf dem Wickelkern (4) ist in einer Aussparung (43) mittels eines Befestigungselementes (44) ein Magnettonband (5) befestigt.On the winding core (4) is in a recess (43) by means of a Fastening element (44) attached to a magnetic tape (5).

Die in Drehrichtung des Pfeiles (n) weisenden Flanken (12) der Nocken (ii) des Wickeldornes (i) sind in Richtung zu der Schulterfläche (31) hinterschnitten ausgebildet.The flanks (12) of the cams pointing in the direction of rotation of the arrow (n) (ii) of the winding mandrel (i) are undercut in the direction of the shoulder surface (31) educated.

Wird nun der Wickeldorn in Drehrichtung des Pfeiles (n) angetrieben, so werden die Nocken (41) und damit der Wickelkern (4) durch die hinterschnittenen Innen (12) der Nocken (11) an die axiale Schulterfläche (31) angelegt. Diese Wirkung soll anhand des Nockens (41) verdeutlicht werden.If the winding mandrel is now driven in the direction of rotation of the arrow (s), so the cams (41) and thus the winding core (4) are undercut through the Inside (12) of the cam (11) placed on the axial shoulder surface (31). This effect should be clarified using the cam (41).
