Abstract

2.1 The winding reels in question are driven at extremely high speeds during the winding of the winding material. For this purpose, they are slipped onto the winding shafts and firmly clamped on these. Since the inner hubs have not hitherto been gripped by the winding shafts, the dissipation of the forces has taken place solely by way of the cover. It has thus been possible for the covers to come loose from the cylindrical cores, with the result that the winding reels have been flung away from the winding shaft in an uncontrolled manner. 2.2 To increase safety, the winding reel according to the invention is designed so that the inner tube (15) has a smooth inner face, and that the inner tube (15) is firmly connected to the cover (14) and to the inner hub (13). For this purpose, the edge of the cover (14) facing away from the end face of the winding reel (10) engages over an extension of the winding reel (10), the said extension being located outside a limiting flange (12). 2.3 The winding reel according to the invention is suitable especially for the winding of cables and wires of small diameter. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Wickelspule für band- oder fadenförmiges Wickelgut mit einem zylindrischen Wickelkern, zwei stirnseitigen Begrenzungsscheiben, einer konzentrisch zur Mittelachse stehenden rohrförmigen, einem Stirnendbereich zugeordneten Innennabe und einem der Innennabe gegenüberliegenden Deckel. Die in Rede stehende Wickelspule wird beim Aufwickeln des Wickelgutes mit einer extrem hohen Drehzahl angetrieben. Dazu wird Sie auf eine Wickelwelle gesteckt und darauf festgeklemmt. Üblicherweise wird die Wickelspule nicht mit der vollen Breite auf die Wickelwelle gesteckt. Die Innennabe wird dann von der Wickelwelle nicht erfaßt, da sie, bezogen auf die Breite der Wickelspule, relativ kurz ist. Die Abtragung der Kräfte erfolgt dann ausschließlich über den Deckel. Durch die dann auftretende extrem hohe Belastung kann es passieren, daß sich der Deckel von dem zylindrischen Kern der Wickelspule löst. Die Wickelspule bewegt sich dann unkontrolliert von der Wickelwelle weg. Die Gefahr, daß dann Personen verletzt werden ist besonders hoch.The present invention relates to a winding spool for strip or thread-shaped winding material with a cylindrical winding core, two end-side limiting disks, a tubular inner hub which is concentric with the central axis and is assigned to an end region, and a cover opposite the inner hub. The winding reel in question is driven at an extremely high speed when winding the winding material. To do this, it is placed on a winding shaft and clamped onto it. Usually the full width of the winding spool is not placed on the winding shaft. The inner hub is then not gripped by the winding shaft, since it is relatively short in relation to the width of the winding spool. The forces are then only transferred via the cover. Due to the extremely high load then occurring, it can happen that the cover detaches from the cylindrical core of the winding spool. The winding spool then moves away from the winding shaft in an uncontrolled manner. The risk that people will be injured is particularly high.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Sicherheit wesentlich zu erhöhen , auch wenn die Wickelspule nur über einen Teil der Breite auf die Wickelwelle gesteckt wird.The present invention has for its object to significantly increase safety, even if the winding spool is only inserted over part of the width on the winding shaft.

Die gestellte Aufgabe wird durch ein Innenrohr mit glatter Innenfläche gelöst, welches mit dem Deckel und der Innennabe fest verbunden ist.The task is solved by an inner tube with a smooth inner surface, which is firmly connected to the cover and the inner hub.

Das Innenrohr liegt konzentrisch zur Mittellängsachse der Wickelspule bzw. zur Drehachse. Der dem Stirnende abgewandte Rand des Deckels ist normalerweise mittels einer Schweißnaht mit einem außerhalb der Begrenzungsscheibe liegenden zylindrischen Ansatz verbunden. Die Schweißnaht wird üblicherweise durch ein Ultraschallverfahren hergestellt. Selbst wenn bei der erfindungsgemäßen Wickelspule diese Schweißnaht zerstört wird, ist es nicht möglich, daß sich die Wickelspule unkontrolliert bewegt, da das Innenrohr noch mit dem Ansatz verbunden ist. Dabei ist es dann besonders zweckmäßig, wenn der freie Rand des Deckels diesen Ansatz übergreift. Dieser Ansatz liegt fluchtend zum zwischen den Begrenzungsscheiben liegenden Wickelkern. Die Wickelwelle ist mit Klemmelementen ausgerüstet, um die Wickelspule festzusetzen. Dabei wirkt sich das Innenrohr mit glatter Innenfläche besonders vorteilhaft aus, da keine störenden Trennähte die Klemmung erschweren oder an die empfindliche Wickelwelle stoßen. Zweckmäßigerweise erstreckt sich das Innenrohr von einem Stirnende der Wickelspule bis zum anderen Stirnende. Es sind nun auch Wickelspulen bekannt, die an wenigstens einer Seite eine Ausnehmung in Form eines Kegelstumpfes aufweisen. Das Innenrohr erstreckt sich dann entweder von einer Stirnfläche der Wickelspule bis zur kegelstumpfförmigen Ausnehmung oder, sofern an beiden Stirnseiten eine Ausnehmung vorgesehen ist, über den Bereich, der zwischen den Ausnehmungen liegt. Die Konstruktion wird besonders einfach, wenn der Deckel und das Innenrohr als ein einstückiges Formteil ausgebildet sind. Da dann eine Verbindungsnaht entfällt, wird die Sicherheit noch zusätzlich erhöht. Üblicherweise besteht die Wickelspule aus einem Kunststoff. Demzufolge ist auch das Formteil ein einstückiges Kunststofformteil . Die Verbindung des Innenrohres mit der Innennabe erfolgt durch eine Klebeschicht oder sinngemäß durch eine Verschweißung mittels eines Lösemittels. Der Kleber bzw. das Lösemittel können vollflächig oder partiell beispielsweise in Form eines oder mehrerer Punkte aufgetragen werden.The inner tube is concentric to the central longitudinal axis of the winding spool or to the axis of rotation. The edge of the cover facing away from the front end is normally connected by means of a weld seam to a cylindrical extension lying outside the limiting disk. The weld seam is usually produced by an ultrasound process. Even if this weld seam is destroyed in the winding spool according to the invention, it is not possible for the winding spool to move in an uncontrolled manner since the inner tube is still connected to the attachment. It is particularly useful if the free edge of the lid overlaps this approach. This approach is aligned with the winding core lying between the limiting discs. The winding shaft is equipped with clamping elements to fix the winding spool. The inner tube with a smooth inner surface has a particularly advantageous effect, since no disruptive separating seams make clamping difficult or come up against the sensitive winding shaft. The inner tube expediently extends from one end of the winding spool to the other end. Winding coils are now also known which have a recess in the form of a truncated cone on at least one side. The inner tube then extends either from an end face of the winding spool to frustoconical recess or, if a recess is provided on both end faces, over the area that lies between the recesses. The construction becomes particularly simple if the cover and the inner tube are formed as a one-piece molded part. Since a connecting seam is then no longer required, safety is additionally increased. The winding spool usually consists of a plastic. As a result, the molded part is also a one-piece plastic molded part. The inner tube is connected to the inner hub by means of an adhesive layer or, analogously, by welding using a solvent. The adhesive or the solvent can be applied over the entire surface or partially, for example in the form of one or more dots.

Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert.The invention is explained in more detail with reference to the accompanying drawings.

eine bevorzugte Ausführungsform der erfindungsgemäßen Wickelspule in Schnittdarstellung.
It shows:
Figure 1
a preferred embodiment of the winding spool according to the invention in a sectional view.

In der Figur 1 ist eine Bi-Konische Wickelspule 10 dargestellt. Sie besteht im wesentlichen aus einem zylindrischen Kern 11 und zwei stirnseitigen Begrenzungsscheiben 12, die im vorliegendem Ausführungsbeispiel schräg zur Mittellängsachse der Wickelspule 10 stehen. Der Schrägungswinkel beträgt 45°. Wie die Figur 1 zeigt, ist die Schrägstellung so gewählt, daß die Begrenzungsscheiben 12, von der Mittellängsachse aus gesehen divergierend zueinander stehen. Wie die Figur zeigt, erstreckt sich der zylindrische Wickelkern nicht über die gesamte Breite der Wickelspule 10, sondern die in der Darstellung linke Stirnfläche verspringt in Richtung zur gegenüberliegenden Stirnfläche. An der in der Darstellung rechten Seite ist die Wickelspule 10 mit einer rohrförmigen Innennabe 13ausgerüstet, die sich von der rechten Stirnfläche in Richtung zur gegenüberliegenden Stirnfläche der Wickelspule 10 erstreckt. Die Länge der Innennabe 13 ist, bezogen auf die Breite der Wickelspule 10 relativ kurz. Im dargestellten Ausführungsbeispiel ist die Länge der Innennabe 13 ca. 1/5tel der Breite der Wickelspule 10. Die Innennabe 13 liegt konzentrisch zur Mittellängsachse der Wickelspule 10. An der der Innennabe 13 gegenüberliegenden linken Seite ist ein Deckel 14 vorgesehen, der mit einem Innenrohr 15 verbunden ist, welches sich von der linken zur rechten Stirnfläche der Wickelspule 10 erstreckt. Im dargestellten Ausführungsbeispiel ist der Deckel 14 und das Innenrohr 15 als ein einstückiges Kunststofformteil ausgebildet. Dabei kann der äußere Rand des Deckels sinngemäß wie ein Kragen gesehen werden. Der der Stirnfläche abgewandte freie Rand des Deckels 14 übergreift den Rand des zylindrischen Kernes 11. Der übergreifende Rand des Deckels 14 ist durch eine nicht dargestellte Schweißnaht mit dem zylindrischen Kern 11 und somit auch mit der Wickelspule 10 fest verbunden. Das dem Deckel 14 gegenüberliegende Ende des Innenrohres 15 ist mit der Innennabe 13 durch eine nicht dargestellte Klebemittelschicht verbunden. Diese Klebemittelschicht kann rundum und somit vollflächig verlaufen oder auch partiell in Form von einigen Punkten aufgetragen sein. Das Innenrohr 15 hat eine glatte Innenfläche mit besonders hoher Oberflächenqualität. Dadurch ist sichergestellt, daß die Spannelemente einer nicht dargestellten Wickelwelle vollflächig angreifen können, um die Wickelspule 10 sicher aufzunehmen. Aus der Zeichnung ergibt sich ohne weiteres, daß eine axiale Verschiebung der Wickelspule 10 selbst dann unmöglich ist, wenn die den Deckel 14 mit dem zylindrischen Kern 11 verbindende Schweißnaht zerstört wird. Aus der Zeichnung ergibt sich ferner,daß der Stirnfläche abgewandt liegende freie Rand des Deckels nach außen versetzt ist, damit das Ende des zylindrischen Kernes übergriffen wird. Der Deckel 14 ist mit einer Bohrung versehen, um die Wickelwelle in das Innenrohr einzuführen.A bi-conical winding spool 10 is shown in FIG. It essentially consists of a cylindrical core 11 and two end-side limiting disks 12, which in the present exemplary embodiment are inclined to the central longitudinal axis of the winding spool 10. The helix angle is 45 °. As shown in FIG. 1, the inclined position is selected such that the limiting disks 12 are diverging from one another as seen from the central longitudinal axis. As the figure shows, stretches the cylindrical winding core does not protrude over the entire width of the winding spool 10, but the end face on the left in the illustration jumps in the direction of the opposite end face. On the right side in the illustration, the winding spool 10 is equipped with a tubular inner hub 13, which extends from the right end face in the direction of the opposite end face of the winding spool 10. The length of the inner hub 13 is relatively short in relation to the width of the winding spool 10. In the exemplary embodiment shown, the length of the inner hub 13 is approximately 1/5 the width of the winding spool 10. The inner hub 13 is concentric with the central longitudinal axis of the winding spool 10. On the left side opposite the inner hub 13, a cover 14 is provided, which is connected to an inner tube 15 is connected, which extends from the left to the right end face of the winding spool 10. In the illustrated embodiment, the cover 14 and the inner tube 15 are formed as a one-piece molded plastic part. The outer edge of the lid can be seen as a collar. The free edge of the cover 14 facing away from the end face overlaps the edge of the cylindrical core 11. The overlapping edge of the cover 14 is fixedly connected to the cylindrical core 11 and thus also to the winding spool 10 by a weld seam (not shown). The end of the inner tube 15 opposite the cover 14 is connected to the inner hub 13 by an adhesive layer, not shown. This adhesive layer can run all around and thus over the entire surface or can also be partially applied in the form of a few dots. The inner tube 15 has a smooth inner surface with a particularly high surface quality. This ensures that the tensioning elements of a winding shaft, not shown, can engage over the entire area around the winding spool 10 to record safely. It is readily apparent from the drawing that an axial displacement of the winding spool 10 is impossible even if the weld seam connecting the cover 14 to the cylindrical core 11 is destroyed. The drawing also shows that the free edge of the cover facing away from the end face is offset outwards so that the end of the cylindrical core is overlapped. The cover 14 is provided with a bore in order to insert the winding shaft into the inner tube.

In der Figur 1 ist eine Ausführung dargestellt, bei der sich das Innenrohr 15 von einer Stirnseite bis zu anderen, d. h. über die volle Breite der Wickelspule 10 erstreckt. Es sind jedoch auch Spulen bekannt, die an einer oder an beiden Seiten mit einer kegelstumpfförmigen Ausnehmung versehen sind. Bei dieser Ausführung erstreckt sich das Innenrohr über den Bereich zwischen den beiden Ausnehmungen bzw. wenn die Wickelspule 10 nur an einer Seite mit einer Ausnehmung versehen ist von der gegenüberliegenden Stirnseite bis zum kegelstumpfförmigen Ansatz.1 shows an embodiment in which the inner tube 15 extends from one end face to the other, ie. H. extends over the full width of the winding spool 10. However, coils are also known which are provided with a truncated cone-shaped recess on one or both sides. In this embodiment, the inner tube extends over the area between the two recesses or, if the winding spool 10 is provided with a recess on only one side, from the opposite end face to the frustum-shaped shoulder.

Bei der dargestellten Ausführung ist der zum zylindrischen Kern 11 fluchtende, außerhalb der linken Begrenzungsscheibe 12 liegende Ansatz durch das Bezugszeichen 16 gekennzeichnet. Die Festlegung des Deckels 14 am Innenrohr 15 ist fertigungstechnisch vorteilhaft, da das größere Teil, nämlich der Wickelkörper auf einer entsprechend großen Maschine ohne Leistungsminderung gefertigt werden kann, während das kleinere Teil,bestehend aus dem Deckel 14 und dem Innenrohr 15 auf einer kleineren Maschine gefertigt werden kann. Durch die Ausbildung als einstückiges Formteil vermindert sich die Leistung, die sich dann nur bei der kleineren Maschine auswirkt.In the embodiment shown, the lug aligned with the cylindrical core 11 and lying outside the left-hand limiting disk 12 is identified by the reference symbol 16. The fixing of the cover 14 on the inner tube 15 is advantageous in terms of production technology, since the larger part, namely the winding body, can be produced on a correspondingly large machine without a reduction in performance, while the smaller part, consisting of the cover 14 and the inner tube 15, is produced on a smaller machine can be. The design as a one-piece molded part reduces the output, which then only affects the smaller machine.
