Description
Die Erfindung betrifft eine Zentrierbüchse zum Zentrieren und Verbinden aufeinanderstehender Wickelhülsen, mit zumindest einem zylindrischen Teil, der zu beiden Seiten einer Mittenebene der Zentrierbüchse verläuft, siehe z.B. US-A-3 759 460.The invention relates to a centering sleeve for centering and connecting stacked cores, with at least one cylindrical part facing too both sides of a center plane of the centering sleeve runs, see e.g. US-A-3 759 460.
Zentrierbüchsen dienen zum Verbinden und Zentrieren der Wickelhülsen von aufeinanderstehenden Wickelrollen, die aus beliebigem Material, wie z.B. Kunststoff-, Metallfolie, Papier, Stoff und dergleichen, gewickelt sind. Bekannte Zentrierbüchsen bestehen aus einem zylindrischen Körper mit einem umlaufenden Ring oder Wulst. Dieser Wulst verhindert, daß die Zentrierbüchsen in der Wickelhülse, in die sie eingesetzt werden, versinken. Nachteilig ist bei dieser Ausführungsform der Zentrierbüchse, daß der Wulst verhindert, daß die Wickelhülsen von übereinander gestapelten Wickelrollen nicht unmittelbar aufeinanderstehen, sondern durch einen Spalt getrennt sind. Bedingt durch diesen Spalt zwischen den Wickelrollen, besteht die Gefahr, daß die obere Wickelrolle teleskopieren kann. Um dies auszuschließen, muß der Spalt durch Auffüllmaterial, wie Wellpappe oder ähnliches Material, geschlossen werden. Dadurch wird auch die Stabilität und die Transportsicherheit der Versandeinheiten aus mehreren Wickelrollen reduziert und darüber hinaus zusätzliches Verpackungsmaterial benötigt, das entsorgt werden muß. Infolge von Verpackungsordnungen in verschiedenen Ländern, die minimale Transportverpackungen vorschreiben, besteht bei den Empfängern von verpacktem Gut, wie beispielsweise verpackten Wickelrollen, die aus Folien schmaler Schnittbreite bestehen, das Bedürfnis, die Transportverpackung so gering wie möglich zu halten.Centering bushes are used for connecting and centering the winding tubes of winding rolls standing on top of each other, made of any material, such as Plastic-, Metal foil, paper, fabric and the like, are wrapped. Known centering sleeves consist of a cylindrical body with a circumferential ring or bead. This bead prevents the centering bushes in the winding tube in which they are inserted will sink. The disadvantage of this Embodiment of the centering sleeve that the bead prevents the winding tubes from being stacked on top of each other Do not stand winding rolls directly on top of each other, but are separated by a gap. Conditionally through this gap between the winding rolls, there is a risk that the upper winding roll will telescope can. To exclude this, the gap through filling material, such as corrugated cardboard or the like Material to be closed. This also makes the Stability and transport security of the shipping units reduced from several winding rolls and additional packaging material required, that has to be disposed of. As a result of packaging regulations in different countries, the minimum Prescribe transport packaging exists at the recipients of packaged goods, such as packaged winding rolls, the narrower of foils Cutting width exist, the need, the transport packaging to keep it as low as possible.
Aufgabe der Erfindung ist es, eine Zentrierbüchse zu schaffen, welche die Stabilität und Transportsicherheit von Versandeinheiten aus aufeinanderstehenden Wickelrollen verbessert und den Einsatz von zusätzlichen Transportverpackungsmitteln überflüssig macht.The object of the invention is to provide a centering sleeve create which the stability and transport security of shipping units from each other Improved winding rolls and the use of additional Makes transport packaging unnecessary.
Diese Aufgabe wird erfindungsgemäß in der Weise gelöst, daß die Zentrierbüchse zu beiden Seiten des zylindrischen Teils konisch geformt ist und daß am Außenumfang des zylindrischen Teils scharfkantige Vorsprünge angeordnet sind, deren Enden abgerundet sind.According to the invention, this object is achieved in such a way that that the centering sleeve on both sides of the cylindrical part is conical and that on Outer circumference of the cylindrical part with sharp edges Projections are arranged, the ends of which are rounded are.
In Ausgestaltung der Erfindung sind der zylindrische Teil und die daran zu beiden Seiten anschließenden konischen Teile hohl und in sich geschlossen ausgebildet, wodurch eine Material- und eine damit einhergehende Gewichtsersparnis erreicht wird.In an embodiment of the invention, the cylindrical Part and the adjoining on both sides conical parts are hollow and self-contained, whereby a material and an accompanying Weight saving is achieved.
In weiterer Ausgestaltung sind zylindrische Teile zu beiden Seiten der Mittenebene angeordnet, gehen die zylindrischen Teile in zur Mittenachse hin konisch geformte Teile über und sind am Außenumfang der Zentrierbüchse in der Mittenebene als Vorsprünge scharfkantige Dornen mit abgerundeten Enden angeordnet.In a further embodiment, cylindrical parts are closed Arranged on both sides of the central plane, the cylindrical parts in conical towards the central axis molded parts over and are on the outer circumference of the centering sleeve sharp-edged in the center plane as projections Thorns arranged with rounded ends.
Zweckmäßigerweise ist der Außendurchmesser der Zentrierbüchse in der Mittenebene gleich dem Innendurchmesser der Wickelhülsen. Dabei liegen die Enden der Dornen auf einem Kreis, dessen Durchmesser größer als der Innendurchmesser der Wickelhülsen ist. The outer diameter of the centering sleeve is expedient in the center plane equal to the inside diameter of the winding tubes. The ends of the Thorns on a circle whose diameter is larger than is the inside diameter of the winding tubes.
Die weitere Ausgestaltung der Erfindung ergibt sich aus den Merkmalen der Ansprüche 6 bis 9.The further embodiment of the invention results from the features of claims 6 to 9.
Für den Versand werden die Wickelrollen im allgemeinen hochkant gestellt, und bei schmalen Formaten bzw. Breiten der augewickelten Folienschnitte werden mehrere Wickelrollen aufeinandergestellt bzw. übereinandergestapelt. Die übereinanderstehenden Wickelhülsen haben gleiche Abmessungen. Sobald eine Wickelrolle hochkant gestellt ist, wird in deren Wickelhülse, die im allgemeinen aus Pappe besteht, eine Zentrierbüchse nach der Erfindung eingepaßt, wobei deren Vorsprünge in der Mittenebene zunächst auf dem oberen Rand der Wickelhülse aufliegen. Wird auf diese Wickelrolle eine weitere Wickelrolle aufgesetzt, dann versinken infolge des Wickelrollengewichts die scharfkantigen Vorsprünge bzw. Dornen in den Wickelhülsen und werden in diese eingepreßt. Bei Wickelhülsen aus hartem Material, z.B. aus Kunststoff oder Metall, werden die Hülsenkanten bzw. -ränder gefast, so daß die Vorsprünge in der Mittenebene der Zentrierbüchse an der Fase anliegen, wodurch die Zentrierbüchse zentriert und die Wickelhülsen gegen Verrutschen gesichert werden.In general, the winding rolls are used for shipping placed upright, and for narrow formats or The width of the unwrapped film cuts becomes several Winding rolls placed on top of one another or stacked on top of each other. The stacking cores have the same dimensions. Once a winding roll is placed upright, in its winding tube, the generally made of cardboard, a centering sleeve fitted according to the invention, the projections of which in the middle plane first on the upper edge of the Fit the winding tube. Will on this winding roll put on another winding roll, then sink due to the weight of the reel the sharp-edged Projections or thorns in the winding tubes and pressed into this. For winding cores made of hard Material, e.g. made of plastic or metal Chamfered edges or edges so that the projections in the center plane of the centering sleeve on the Chamfer fit, which centers the centering sleeve and the winding sleeves are secured against slipping.
Mit der Erfindung werden die Vorteile erzielt, daß die Zentrierbüchse selbstzentrierend ist und daß durch den Preßsitz der Vorsprünge bzw. Dornen in dem Material der Wickelhülsen die Wickelrollen gegen Verrutschen gesichert sind. Als weiterer Vorteil kommt hinzu, daß die beiden Wickelrollen ohne Spalt dicht aufeinander aufsitzen, so daß ein Teleskopieren der oberen Wickelrolle weitgehend vermieden wird, im Gegensatz zu bekannten Zentrierbüchsen, bei denen stets ein Spalt zwischen den aufeinander aufliegenden Wickelrollen besteht, der das Teleskopieren der oberen Wickelrolle begünstigt. Die Zentrierbüchse nach der Erfindung macht zusätzliches Verpackungsmaterial überflüssig, so daß die Packmittelabfälle weitgehend reduziert werden. Von Vorteil ist auch, daß die Zentrierbüchse ein Mehrwegpackmittel ist, d.h. mehrfach wiederverwendbar ist. Durch die Selbstzentrierung und den Preßsitz der Zentrierbüchse ergibt sich eine hohe Stabilität der Versandeinheiten aus Wickelrollen und eine große Transportsicherheit dieser Versandeinheiten.With the invention, the advantages are achieved that the centering sleeve is self-centering and that by the press fit of the projections or thorns in the Material of the winding sleeves to prevent the winding rollers from slipping are secured. Another advantage comes added that the two winding rolls are tight without a gap sit on top of each other, so that the telescoping upper winding roll is largely avoided in Contrary to known centering bushes, where always a gap between the one on top of the other There is winding rolls, which is the telescoping of the top Favored winding roll. The centering rifle after the invention makes additional packaging material superfluous, so that the packaging waste largely be reduced. Another advantage is that the centering sleeve is a reusable packaging, i.e. multiple is reusable. Through self-centering and the press fit of the centering sleeve is high Stability of the shipping units from winding rolls and great transport security for these shipping units.

Figur 1 zeigt in schematischer Schnittansicht zwei
übereinandergestellte Wickelrollen 18 und 19, die jeweils
Wickelhülsen 9 und 10 mit gleichen Abmessungen
aufweisen. Bei den Wickelrollen 18 und 19 handelt es
sich um Rollen, auf denen Material, wie Kunststoff/Metallfolien,
Stoff, Papier oder dergl., aufgewickelt
ist. Die beiden Wickelrollen 18 und 19 bilden
eine sogenannte Versandeinheit für den Transport. Die
beiden Wickelrollen berühren sich entlang einer
Mittenebene 2 und werden durch eine erste Ausführungsform
einer Zentrierbüchse 1 zentriert und gegen
Verrutschen gesichert. Der Innendurchmesser DIW der
Wickelhülsen 9 und 10 ist gleich dem größten Außendurchmesser
D der Zentrierbüchse (vgl. Fig. 2).Figure 1 shows a schematic sectional view of two superposed
Figur 2 zeigt eine Ansicht der Zentrierbüchse 1, die
aus einem zylindrischen Teil 14, dem daran nach oben
anschließenden Teil 15 und dem nach unten sich anschließenden
Teil 16 besteht. Am Außenumfang des
zylindrischen Teils 14 in der Höhe der Mittenebene 2
sind scharfkantige Vorsprünge 8 mit abgerundeten
Enden angeordnet. Der zylindrische Teil 14 erstreckt
sich symmetrisch zu beiden Seiten der Mittenebene 2
der Zentrierbüchse 1. Wie aus der teilweise geschnittenen,
perspektivischen Ansicht der Figur 3 der Zentrierbüchse
1 zu ersehen ist, sind der zylindrische
Teil 14 und die daran zu beiden Seiten anschließenden
konischen Teile 15 und 16 hohl und in sich geschlossen
ausgebildet. Dabei gehen diese Teile 14, 15 und
16 ohne Zwischenwand ineinander über.Figure 2 shows a view of the
Wie aus den Figuren 2 und 3 zu entnehmen ist, weisen
die Vorsprünge 8 scharfe Kanten 11, 12 auf, die senkrecht

the
Anhand von Figur 1 wird kurz erläutert, wie die Zentrierbüchse
1 in die Wickelhülsen 9 und 10 eingesetzt
wird. Die untere Wickelrolle 19 wird hochkant gestellt,
d.h. die Wickelhülse 10 ist senkrecht ausgerichtet.
Die Zentrierbüchse 1 wird dann in die
Wickelhülse 10 im Paßsitz eingefügt, so daß die Vorsprünge
8 auf dem oberen Rand der Wickelhülse 10 aufliegen.
Danach wird die gleichfalls hochkant ausgerichtete
obere Wickelrolle 18 auf die untere Wickelrolle
19 aufgesetzt. Durch das Eigengewicht der
Wickelrolle 18 werden die Vorsprünge 8 in der
Mittenebene 2 in die beiden übereinanderliegenden
Wickelhülsen 10 und 9 eingepreßt. Dadurch wird die
Entstehung eines Luftspaltes in der Mittenebene 2
zwischen den Wickelrollen 18 und 19 vermieden, darüber
hinaus die Zentrierbüchse 1 selbst zentriert,
und durch den Preßsitz werden die beiden Wickelrollen
18 und 19 gegen Verrutschen gesichert. Das Material
der Wickelhülsen 9 und 10 ist im allgemeinen Pappe,
so daß die scharfkantigen Vorsprünge 8 der Zentrierbüchse
1 problemlos in die Wickelhülsen eingepreßt
werden können. Bestehen die Wickelhülsen aus hartem
Material, z.B. aus Kunststoff oder Metall, werden die
Hülsenkanten bzw. -ränder gefast, so daß die Vorsprünge
in der Mittenebene der Zentrierbüchse an der
Fase anliegen, wodurch es zu einer Selbstzentrierung
der Zentrierbüchse und zur Sicherung der Wickelhülsen
gegen Verrutschen kommt.With reference to Figure 1 it is briefly explained how the centering
In Figur 4 ist eine zweite Ausführungsform einer Zentrierbüchse
7 gezeigt, bei der, gegenüber der ersten
Ausführungsform der Zentrierbüchse 1, eine Material- und
Gewichtseinsparung erzielt wird. Bei dieser Zentrierbüchse
7 befinden sich zu beiden Seiten der
Mittenebene 2 mehrere zylindrische Teile 3 und 4, wobei
die oberhalb der Mittenebene liegenden Teile mit
der Bezugszahl 3 und die unterhalb der Mittenebene 2
liegenden Teile mit der Bezugszahl 4 belegt sind. An
die zylindrischen Teile 3 und 4 schließen jeweils zur
Mittenachse 17 der Zentrierbüchse 7 hin konisch geformte
Teile 6 und 7 an. Am Außenumfang der Zentrierbüchse
7 in der Mittenebene 2 sind als Vorsprünge
scharfkantige Dornen 8 angeordnet, deren Anzahl,
ebenso wie bei der ersten Ausführungsform der Zentrierbüchse,
frei wählbar ist und im allgemeinen zwischen
6 und 12, insbesondere 6, beträgt. Die Enden
der Dornen 8 liegen auf einem Kreis, dessen Durchmesser
größer als der Innendurchmesser DIW der Wickelhülsen
ist. Die Enden sind zur Verringerung einer
Verletzungsgefahr abgerundet. Das Anbringen der Zentrierbüchse
7 erfolgt in der gleichen Weise, wie sie
anhand von Fig. 1 für die erste Ausführungsform der
Zentrierbüchse beschrieben ist. Der Außendurchmesser
D der Zentrierbüchse 7 in der Mittenebene 2 ist,
ebenso wie bei der ersten Ausführungsform, gleich dem
Innendurchmesser DIW der Wickelhülsen 9 und 10.FIG. 4 shows a second embodiment of a centering
Wie aus der perspektivischen Ansicht der Figur 5 zu
erkennen ist, sind die zylindrischen Teile 3 und 4
und die damit verbundenen konischen Teile 5 und 6
gleichmäßig über den Umfang der Zentrierbüchse 7 verteilt.
Zwischen je zwei benachbarten Teilen 3 und 5
bzw. 4 und 6 befindet sich eine Lücke 13. Dabei sind
die oberhalb der Mittenebene 2 befindlichen zylindrischen
und die damit verbundenen konischen Teile 3 und
5 gegenüber den unterhalb der Mittenebene 2 befindlichen
zylindrischen und den damit verbundenen Teilen 4
und 6 in der Weise versetzt, daß sich eine Lücke 13
und ein zylindrisches und das damit verbundene konische
Teil 3 und 5 bzw. 4 und 6 abwechselnd gegenüberliegen.
Die zylindrischen Teile und die damit verbundenen
konischen Teile sind hohl ausgebildet, und die
gesamte Zentrierbüchse 7 ist aufgrund der Lücken 13
zwischen den benachbarten Teilen 3 und 5 bzw. 4 und 6
leichter als die erste Ausführungsform der Zentrierbüchse
1. Da die Zentrierbüchse 7 derart geformt ist,
daß sie, im Vergleich zu der Zentrierbüchse 1, nicht
mehr nur aus einem schlanken zylindrischen Körper mit
konisch abgeschrägten Teilen gebildet ist, sondern
horizontale und vertikale Flächen infolge der Lückenbildung
zwischen den miteinander verbundenen Teilen
aufweist, können diese relativ großen horizontalen
und vertikalen Flächen mit optoelektronischen Mitteln
erfaßt werden, so daß die Zentrierbüchse 7 auch für
den automatischen Einsatz mittels Robotern in die
Wickelhülsen besonders geeignet ist.As seen from the perspective view of FIG
can be seen, the cylindrical parts 3 and 4
and the associated
