Abstract
Description
Die Erfindung betrifft einen flanschlosen stapelbaren Wickel kern für aufgewickelte bandförmige Informationsträger, wo bei die Breite der Wickelfläche des Wickelkerns gleich oder geringfügig größer ist als die Breite des aufzuwickelnden Informationsträgers und wobei der Wickelkern eine zentri sche Bohrung enthält und aus mehreren konzentrischen Zonen besteht, welche durch elastisch verformbare in radialer und in Umfangsrichtung verlaufende Zwischenelemente mitein ander verbunden sind, gemäß der deutschen Anmeldung P 41 05 604.The invention relates to a flangeless stackable winding core for wound, band-shaped information carriers, where with the width of the winding area of the winding core equal to or is slightly larger than the width of the rewind Information carrier and where the winding core is a centri contains and from several concentric zones exists, which by elastically deformable in radial and circumferential intermediate elements are connected in accordance with the German application P 41 05 604.
In dieser Anmeldung ist in Fig. 3 ein Wickelkern beschrie ben, dessen äußerer Ring ein Doppel-T-Profil besitzt und dessen elastische Zwischenelemente gleichmäßig in Umfangs richtung verteilt sind und eine kreisringförmige Struktur haben, wobei die elastischen Zwischenelemente in radialer und in Umfangsrichtung verlaufende S-förmige Stege sind.In this application, a winding core is described in Fig. 3 ben, the outer ring has a double-T profile and the elastic intermediate elements are evenly distributed in the circumferential direction and have an annular structure, the elastic intermediate elements in the radial and circumferential direction S -shaped webs are.
Der Vorteil dieser Anordnung liegt darin, daß beim Bewickeln des erfindungsgemäßen Kerns der Wickeldruck sich gleichmäßig auf die Zwischenelemente verteilt, ohne daß sich der äußere Ring gegen den inneren Ring verdreht und daß sich dabei der Durchmesser Di der inneren Bohrung weniger ändert als beim Stand der Technik. Dabei kann auf die sonst übliche Verstärkung des Kunststoff-Materials des Wickelkerns durch Glasfaser oder ähnliches verzichtet werden.The advantage of this arrangement is that when the core according to the invention is wound, the winding pressure is distributed evenly over the intermediate elements without the outer ring rotating against the inner ring and that the diameter D i of the inner bore changes less than in the state of the Technology. The usual reinforcement of the plastic material of the winding core by glass fiber or the like can be dispensed with.
Bei der Weiterarbeit an dieser Erfindung wurde nun gefunden, daß sich beim Bewickeln eines Kerns der oben genannten Art eine besonders niedrige Kompression des inneren Durchmessers Di sowie eine besonders gleichmäßige Kompression des äuße ren Ringes, also eine gleichmäßige Änderung ΔDa entlang des Umfangs ergibt, falls entwederIn the further work on this invention, it has now been found that when a core of the type mentioned above is wound, there is a particularly low compression of the inner diameter D i and a particularly uniform compression of the outer ring, that is to say a uniform change ΔD a along the circumference, if either
- a) der mittlere in Umfangsrichtung verlaufende Teil der S-förmigen Stege gegen den Radiusstrahl jeweils nicht senkrecht, sondern um den gleichen Betrag α, α′ alter nierend angeordnet sind, wobei α, α′ im Bereich von α= 90°-Δα beziehungsweise α′ = 90° + Δα liegt (0°<Δα<90°, bevorzugt 5°Δα15°),a) the middle part of the circumferential direction S-shaped bars against the radius beam are not vertically, but by the same amount α, α ′ age are arranged nierend, wherein α, α 'in the range of α = 90 ° -Δα or α ′ = 90 ° + Δα is (0 ° <Δα <90 °, preferably 5 ° Δα15 °),
- b) die S-förmigen Stege am Außenring beziehungsweise Innen ring so verankert sind, daß an beiden Ringen jeweils zwei Verankerungsstellen zweier benachbarter Stege auf einander folgen.b) the S-shaped webs on the outer ring or inside ring are anchored so that on each ring two anchoring points on two adjacent bars follow each other.
Im Folgenden wird die Erfindung anhand der Zeichnungen näher erläutert und zwar zeigtIn the following, the invention will be explained in more detail with reference to the drawings explained and shows
Fig. 1 den oben dargestellten Fall a), Fig. 1 shows the case shown above a),
Fig. 2 den oben dargestellten Fall b). Fig. 2 shows the case b) above.
Gemäß Fig. 1 ist der mittlere Teil (3, 3′) der S-förmigen Stege (7) , welche den äußeren Ring (1) mit dem inneren Ring (2) des Wickelkerns verbinden, gegen den Radiusstrahl (6) um den Winkel α,α′ geneigt, wobei der Winkel in Umfangs richtung jeweils alternierend um den gleichen Betrag wech selt. Beispielsweise beträgt der Winkel α,α′ jeweils 75°, 105°, 75°, 105° und so weiter. Vorzugsweise liegt die Ab weichung gegen die Senkrechte zwischen 5° und 15°.Referring to FIG. 1, the central part (3, 3 ') of the S-shaped webs (7) connecting the outer ring (1) with the inner ring (2) of the winding core against the radial line (6) by the angle α, α 'inclined, the angle alternating in the circumferential direction alternating by the same amount. For example, the angle α, α 'is 75 °, 105 °, 75 °, 105 ° and so on. The deviation from the vertical is preferably between 5 ° and 15 °.
Eine andere erfindungsgemäße Weiterentwicklung stellt die Fig. 2 dar. Dabei ist im Gegensatz zur Anordnung nach Fig. 1 der mittlere in Umfangsrichtung verlaufende Teil 3 der S-förmigen Stege (7, 7′) zwar immer senkrecht zum Radius strahl angeordnet, jedoch sind die radial verlaufenden Ver bindungsstücke (4, 4′) der Stege (7, 7′), welche mit dem äußeren Ring (1) verbunden sind sowie die entsprechenden Verbindungsstücke (5, 5′), welche mit dem inneren Ring (2) verbunden sind, so angeordnet, daß in Umfangsrichtung je weils zwei Verbindungsstellen am gleichen Ring aufeinander folgen oder mit anderen Worten, daß jeweils zwei S-förmige elastische Stege (7, 7′) spiegelbildlich gegeneinander ver setzt aufeinanderfolgen.Another development according to the invention is shown in FIG. 2. In contrast to the arrangement according to FIG. 1, the middle part 3 of the S-shaped webs ( 7 , 7 ') running in the circumferential direction is always arranged perpendicularly to the radius, but they are radial Ver Ver connecting pieces ( 4 , 4 ') of the webs ( 7 , 7 ') which are connected to the outer ring ( 1 ) and the corresponding connecting pieces ( 5 , 5 ') which are connected to the inner ring ( 2 ) , arranged so that in the circumferential direction each two connection points on the same ring follow one another or in other words that two S-shaped elastic webs ( 7 , 7 ') are mirror images of each other in succession.
Voraussetzung für die beiden dargestellten Anordnungen ist, daß jeweils eine geradzahlige Anzahl von S-förmigen Zwi schenstegen in dem erfindungsgemäßen Wickelkern vorhanden ist.The prerequisite for the two arrangements shown is that each an even number of S-shaped Zwi ribs present in the winding core according to the invention is.
