Description

Die Erfindung betrifft eine Bandagiermaschine zum Umwickeln von langgestreckten Produkten, wie Schläuche, Kabel, Rohre u .dgl., mit einem bandförmigen Material, mit einer Wickelscheibe, die um eine zur Scheibenfläche senkrechte Drehachse rotierend antreibbar ist und eine mit der Drehachse fluchtende Öffnung zum Durch­führen des langgestreckten Produktes in Richtung der Drehachse aufweist, mit einer auf der Wickelscheibe um eine zu deren Drehachse parallele Achse drehbar gelagerte Wickeltrommel für das bandförmige Material und mit einem auf der Wickelscheibe angeordneten Umlenkdorn, dessen Längsachse zur Umlenkung des bandförmigen Materials in einem Winkelα zur Drehachse der Wickeltrommel angeordnet ist.The invention relates to a bandaging machine for wrapping elongated products, such as hoses, cables, pipes and the like, with a band-shaped material, with a winding disc which can be driven in rotation about an axis of rotation perpendicular to the surface of the disc, and an opening which is aligned with the axis of rotation for passage of the elongated product in the direction of the axis of rotation, with a winding drum rotatably mounted on the winding disc about an axis parallel to its axis of rotation for the band-shaped material and with a deflection mandrel arranged on the winding disc, the longitudinal axis for deflecting the band-shaped material at an angle α to the axis of rotation of the Winding drum is arranged.

Bei derartigen Bandagiermaschinen ist durch die parallele Anordnung der Drehachsen der Wickelscheibe und der Wickeltrommel ein Umlenkdorn erforderlich, der das bandförmige Material aufgrund seiner Ausrichtung in einem Winkel α zur Drehachse der Wickeltrommel um einen Winkel 2 α in Richtung des zu umwickelnden Produktes umlenkt. Der Umlenkdorn ist hierzu als zylindrischer Stift ausgebildet, der auf der Wickel­scheibe in der gewünschten Winkelanordnung starr befestigt ist, so daß das bandförmige Material während des Wickelvorganges reibend über die Oberfläche des Umlenkdorns geführt wird. Bei textilen Bändern funktioniert dies problemlos, da zwischen dem Band und der glatten Umfangsfläche des Umlenkdorns nur eine geringe Reibung entsteht und da textile Bänder relativ hohe Zugkräfte schadlos aufnehmen können. Hierbei können Wickelscheibendrehzahlen von 500 bis 600 Umdrehungen pro Minute erreicht werden. Insbesondere bei der Herstellung von Kabeln oder Schläuchen kommt es jedoch häufig vor, daß die Pro­dukte mit Rohgummistreifen umwickelt werden müssen. Dabei entsteht jedoch zwischen dem stillstehenden Umlenkdorn und dem Rohgummistreifen eine hohe Reibung, so daß es aufgrund der Empfindlichkeit des Gummima­terials und durch die zur Überwindung der Reibung erforderlichen hohen Zugkräfte zu Deformationen oder gar zum Zerreißen des Rohgummibandes kommt. Zur Lösung dieses Problems ist es bekannt, die Ober­fläche des Umlenkdornes mit einer Beschichtung, insbesondere einer Teflonbeschichtung, zu versehen, um die Reibung herabzusetzen. Damit werden jedoch nur Wickelscheibendrehzahlen von maximal 200 Umdrehungen pro Minute erreicht, wodurch die Fertigung sehr teuer wird. Weiterhin wurde versucht, den Umlenkdorn drehbeweglich zu lagern, was jedoch dazu führt, daß das bandförmige Material aufgrund seiner Winkel­anordnung zur Längsachse des Umlenkdornes während des Wickelvorganges in Richtung der Längsachse des Umlenkdorns "wegwandert", was ebenfalls zu seiner Zerstörung führt. Diese Möglichkeit scheidet daher zur Lösung des aufgezeigten Problems von vornherein aus.In such bandaging machines, a parallel mandrel is required due to the parallel arrangement of the axes of rotation of the winding disk and the winding drum, which deflects the band-shaped material due to its orientation at an angle α to the axis of rotation of the winding drum by an angle 2 α in the direction of the product to be wrapped. For this purpose, the deflecting mandrel is designed as a cylindrical pin which is rigidly attached to the winding disk in the desired angular arrangement, so that the strip-shaped material is rubbed over the surface of the deflecting mandrel during the winding process. In the case of textile belts, this works without any problems, since there is only little friction between the belt and the smooth peripheral surface of the deflecting mandrel and since textile belts can absorb relatively high tensile forces without damage. Winding disc speeds of 500 to 600 revolutions per minute can be achieved here. However, especially in the manufacture of cables or hoses, it often happens that the products have to be wrapped with raw rubber strips. However, this creates a high level of friction between the stationary deflection mandrel and the raw rubber strip, so that deformation or even tearing of the raw rubber band occurs due to the sensitivity of the rubber material and the high tensile forces required to overcome the friction. To solve this problem, it is known to provide the surface of the deflecting mandrel with a coating, in particular a Teflon coating, in order to reduce the friction. However, this only results in a maximum winding speed of 200 revolutions reached per minute, which makes production very expensive. Furthermore, attempts have been made to mount the deflecting mandrel in a rotationally movable manner, but this leads to the band-shaped material "migrating" due to its angular arrangement to the longitudinal axis of the deflecting mandrel during the winding process in the direction of the longitudinal axis of the deflecting mandrel, which likewise leads to its destruction. This option is therefore ruled out from the outset to solve the problem shown.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Bandagiermaschine der eingangs beschrie­benen Art derart zu verbessern, daß auch zu bzw. reißempfindliche Materialien mit hohen Wickelgeschwindigkeiten verarbeitet werden können.The present invention is therefore based on the object of improving the bandaging machine of the type described at the outset in such a way that materials sensitive to or tearing can also be processed at high winding speeds.

Erfindungsgemäß wird dies dadurch erreicht, daß der Umlenkdorn derart in Abhängigkeit von dem Winkel α diaboloförmig ausgebildet ist, daß bei Umschlingung des Umlenkdornes durch das bandförmige Material am Anfang der Umschlingung eine Berührungsgerade zwischen der Umfangsfläche des Umlenkdornes und dem bandförmigen Material gebildet ist, die ebenso wie alle zu dieser Berührungsgeraden parallel auf der Bandebene liegenden Berührungsgeraden senkrecht zur Bandlängsachse angeordnet sind, wobei die Umfangs­fläche des Umlenkdornes derart antreibbar ist, daß die Relativgeschwindigkeit zwischen der Umfangsfläche und dem bandförmigen Material gleich Null ist. Durch diese vorteilhafte Ausgestaltung ist einerseits die Reibung zwischen dem Umlenkdorn und dem bandförmigen Material eliminiert, so daß beim Wickelvorgang sehr viel geringere Zugkräfte als bisher auftreten,und andererseits entstehen trotz der Bewegung der Umlenkdorn-Umfangsfläche während des Wickelvorganges auf dem Umlenkdorn keinerlei quer zur Bandlängsachse wirkenden Kraftkomponenten, da alle Berührungsgeraden zwischen dem Umlenkdorn und dem Band senkrecht zur Bandlängsachse angeordnet sind. Hierdurch können auch mit den zugempfindlichsten Bandmaterialien Wickeldrehzahlen von bis zu 600 Umdrehungen pro Minute erreicht werden. Weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung sind in den Unteransprüchen enthalten .According to the invention this is achieved in that the deflecting mandrel is designed in a diaboloidal manner as a function of the angle α such that when the deflecting mandrel is wrapped through the band-shaped material at the beginning of the wrapping a straight line of contact is formed between the circumferential surface of the deflecting mandrel and the band-shaped material all of the straight lines of contact lying parallel to this on the band plane are arranged perpendicular to the longitudinal axis of the band, the peripheral surface of the deflecting mandrel being drivable such that the relative speed between the peripheral surface and the band-shaped material is zero. This advantageous embodiment, on the one hand, eliminates the friction between the deflecting mandrel and the band-shaped material, so that tensile forces are much lower during the winding process occur as before, and on the other hand, despite the movement of the deflecting mandrel peripheral surface during the winding process on the deflecting mandrel no force components acting transversely to the longitudinal axis of the band, since all lines of contact between the deflecting mandrel and the band are arranged perpendicular to the longitudinal axis of the band. As a result, winding speeds of up to 600 revolutions per minute can be achieved even with the most sensitive strip materials. Further advantageous design features of the invention are contained in the subclaims.

Eine erfindungsgemäße Bandagiermaschine 1 weist einen Maschinenrahmen 2 auf, der eine Wickelscheibe 3 trägt, die um eine zur Scheibenfläche senkrechte, vorzugsweise horizontale Drehachse 4 rotierend antreib­bar ist. Die Wickelscheibe 3 weist eine mit der Drehachse 4 fluchtende Öffnung 5 zum Durchführen eines mit einem bandförmigen Material 6 zu umwickeln­den langgestreckten Produktes 7, wie Kabel, Schläuche, Rohre usw., auf, wobei die Drehachse 4 der Wickelscheibe 3 und die Längsachse 9 des zu bandagierenden Produktes 7 zusammenfallen.A bandaging machine 1 according to the invention has a machine frame 2 which carries a winding disk 3 which can be driven in rotation about an axis of rotation 4 which is perpendicular to the disk surface, preferably horizontal. The winding disc 3 has an opening 5 aligned with the axis of rotation 4 for the passage of an elongated product 7 to be wrapped with a band-shaped material 6, such as cables, hoses, pipes, etc., the axis of rotation 4 of the winding disc 3 and the longitudinal axis 9 of the bandaging product 7 coincide.

Die Wickelscheibe 3 trägt eine Wickeltrommel 10 für das Bandmaterial 6, die um eine zur Drehachse 4 der Wickelscheibe 3 parallele Achse 11 drehbar gelagert ist. Bei Rotation der Wickelscheibe 3 wird somit die Wickeltrommel 10 mit dem bandförmigen Material 6 um das langgestreckte Produkt 7 herumgeführt. Zum Umlenken des Bandmaterials 6 in Richtung des zu umwickelnden Produktes 7 ist auf der Wickelscheibe 3 ein Umlenkdorn 12 angeordnet, dessen Längsachse 13 in einem Winkel α zu Drehachse 11 der Wickeltrommel 10 angeordnet ist, wodurch das bandförmige Material 6 um einen Umlenkwinkel 2 α umgelenkt wird (Fig.2).The winding disc 3 carries a winding drum 10 for the strip material 6, which is rotatably mounted about an axis 11 parallel to the axis of rotation 4 of the winding disc 3. When the winding disk 3 rotates, the winding drum 10 with the band-shaped material 6 is thus guided around the elongated product 7. To deflect the strip material 6 in the direction of the product 7 to be wrapped, a deflection mandrel 12 is arranged on the winding disk 3, the longitudinal axis 13 of which is arranged at an angle α to the axis of rotation 11 of the winding drum 10, as a result of which the strip-shaped material 6 is deflected by a deflection angle 2 α (Fig.2).

Zum Bandagieren wird die Wickelscheibe 3 in Richtung des Pfeiles 14 in Fig. 1 in Rotation versetzt und das langgestreckte Produkt 7 mit einer an die Drehzahl der Wickelscheibe 3 angepaßten Vorschubgeschwindigkeit in Richtung des Pfeiles 15 in Fig. 2 durch die Öffnung 5 der Wickelscheibe 3 hindurchgeführt.For bandaging, the winding disk 3 is set in rotation in the direction of the arrow 14 in FIG. 1 and the elongated product 7 is passed through the opening 5 of the winding disk 3 in the direction of arrow 15 in FIG. 2 at a feed rate adapted to the rotational speed of the winding disk 3 .

Darüber hinaus ist es mit der erfindungsgemäßen Bandagiermaschine 1 aber auch möglich, bandagierte Produkte wieder auszuwickeln, indem die Wickelscheibe 3 in Pfeilrichtung 16 gedreht und das langgestreckte Produkt 7 in Pfeilrichtung 17 bewegt wird. In diesem Fall ist ein Antrieb der Wickeltrommel 10 vorgesehen, um das abgewickelte Bandmaterial 6 wieder aufwickeln zu können.In addition, it is also possible with the bandaging machine 1 according to the invention to unwrap bandaged products again by rotating the winding disc 3 in the direction of the arrow 16 and moving the elongated product 7 in the direction of the arrow 17. In this case, a drive of the winding drum 10 is provided in order to be able to rewind the unwound strip material 6.

Während des Wickelns und/oder Abwickelns sorgt eine auf der Wickelscheibe 3 angeordnete Kraftmeßvorrichtung 19 durch Regelung der Bremsung und/oder des Antriebes der Wickeltrommel 10 für eine gleichmäßige Spannung des Bandmaterials 6. Zum Antrieb der Wickeltrommel 10 dient zweckmäßigerweise ein regelbarer Gleichstrom­antrieb.During the winding and / or unwinding, a force measuring device 19 arranged on the winding disk 3 ensures uniform tension of the strip material 6 by regulating the braking and / or the drive of the winding drum 10. A controllable DC drive is expediently used to drive the winding drum 10.

Erfindungsgemäß ist nun der Umlenkdorn 12 (Fig. 3 bis 5) derart in Abhängigkeit von dem Winkel α diaboloförmig ausgebildet, daß bei Umschlingung des Umlenkdornes 12 durch das band­förmige Material 6 am Anfang der Umschlingung eine Berührungsgerade zwischen dem Umlenkdorn 12 und dem bandförmigen Material 6 gebildet ist, die ebenso wie alle zu dieser Berührungsgeraden parallel auf der Bandebene liegenden Berührungsgeraden senkrecht zur Bandlängsachse 21 angeordnet sind. Weiterhin ist die Umfangsfläche des Umlenkdornes 12 erfindungs­gemäß derart antreibbar, daß die zwischen ihr und dem bandförmigen Material 6 auftretende Relativge­schwindigkeit gleich Null ist, wodurch keinerlei Reibung zwischen dem Umlenkdorn 12 und dem band­förmigen Material 6 mehr auftreten kann.According to the invention, the deflecting mandrel 12 (FIGS. 3 to 5) is designed in a diaboloidal manner depending on the angle α such that when the deflecting mandrel 12 is wrapped around by the band-shaped material 6, a straight line of contact between the deflecting mandrel 12 and the band-shaped material 6 is formed at the beginning of the wrapping which, like all of the straight lines of contact lying parallel to this line of contact, are arranged perpendicular to the longitudinal axis 21 of the band. Furthermore, the peripheral surface of the deflection mandrel 12 can be driven according to the invention in such a way that the relative speed occurring between it and the band-shaped material 6 is zero, as a result of which no friction between the deflection mandrel 12 and the band-shaped material 6 can occur anymore.

Im dargestellten Ausführungsbeispiel der Erfindung ist die Umfangsfläche des Umlenkdornes 12 von über den Umfang verteilt angeordneten Stangen 22 gebildet, deren Enden auf zwei bezüglich der Längsachse 13 des Umlenkdornes 12 konzentrischen Kreisen 23 gleichen Durchmessers angeordnet und gleichmäßig voneinander beabstandet sind. Diese Stangen 22 sind in Fig.3 in zueinander paralleler Anordnung dargestellt, wodurch der durch die Umfangsfläche d.h. seine Hüll­fläche, begrenzte Umlenkdorn 12 zylindrisch ist. Durch gemeinsame Drehung der Enden der Stangen 22, d.h. des Kreisbogens 23 um die Achse 13 relativ zu den gegenüberliegenden Stangenenden in Richtung des Doppelpfeiles 24 wird dann die in Fig. 4 darge­stellte Anordnung der Stangen 22 erreicht; der durch die Umfangsfläche, d.h. die Hüllfläche, begrenzte Körper ist hierdurch erfindungsgemäß doppelkonisch und diaboloartig ausgebildet. Die Anpassung der Ausbildung des Umlenkdornes 12 an den Winkel α kann somit vorteilhafterweise durch das Maß der gegenseitigen Verdrehung der gegenüberliegenden Kreise 23 erfolgen.In the illustrated embodiment of the invention, the peripheral surface of the deflecting mandrel 12 is formed by rods 22 arranged distributed over the circumference, the ends of which are arranged on two circles 23 of the same diameter concentric with respect to the longitudinal axis 13 of the deflecting mandrel 12 and are evenly spaced from one another. These rods 22 are shown in a parallel arrangement in FIG. its envelope surface, limited deflection mandrel 12 is cylindrical. By rotating the ends of the rods 22 together, i.e. of the circular arc 23 about the axis 13 relative to the opposite rod ends in the direction of the double arrow 24, the arrangement of the rods 22 shown in FIG. 4 is then achieved; by the peripheral surface, i.e. the envelope surface, limited body is thus designed according to the invention double conical and diabolo. The adaptation of the design of the deflecting mandrel 12 to the angle α can thus advantageously be achieved by the degree of mutual rotation of the opposing circles 23.

Um zu erreichen, daß die Relativgeschwindigkeit zwischen der Umfangsfläche des Umlenkdornes 12 und dem Bandmaterial 6 gleich Null ist, sind erfindungs­gemäß drei Ausbildungen möglich. Erstens kann der ganze Umlenkdorn 12 um seine Längsachse 13 drehbar gelagert sein, zweitens können die Stangen 22 an dem Umlenkdorn 12 drehbar gelagert sein und drittens können die Stangen 22 drehbar gelagerte Hülsen (nicht dargestellt) tragen.In order to ensure that the relative speed between the peripheral surface of the deflection mandrel 12 and the strip material 6 is zero, three configurations are possible according to the invention. First, the entire deflecting mandrel 12 can be rotatably supported about its longitudinal axis 13, secondly the rods 22 can be rotatably supported on the deflecting mandrel 12, and thirdly, the rods 22 can carry sleeves (not shown) which are rotatably mounted.

Es ist vorteilhaft, wenn die Stangen 22 zwischen zwei auf einer zentrischen Achse 25 angeordneten Scheiben 26 befestigt sind, die in Längsrichtung der Achse 25 voneinander beabstandet und parallel zueinander angeordnet sind, wobei die Achse 25 senk­recht zu den Scheiben 26 angeordnet ist.It is advantageous if the rods 22 are fastened between two disks 26 arranged on a central axis 25, which are spaced apart from one another in the longitudinal direction of the axis 25 and are arranged parallel to one another, the axis 25 being arranged perpendicular to the disks 26.

Bei einer bevorzugten Ausführungsform der Erfindung ist die Achse 25 des Umlenkdornes 12 zur Einstellung des Winkels α schwenkbeweglich auf der Wickelscheibe 3 gelagert, da hierdurch auch der Umlenkwinkel 2 α einstellbar ist. Zur erforderlichen Anpassung der Form der Umfangsfläche des Umlenkdornes 12 an den Winkel α ist in diesem Fall erfindungsgemäß zumindest eine der Scheiben 26 auf der Achse 25 verdrehbar gelagert. Die Stangen 22 sind über Gelenkverbindungen an den Scheiben 26 befestigt.In a preferred embodiment of the invention, the axis 25 of the deflection mandrel 12 is pivotally mounted on the winding disk 3 for setting the angle α, since this also allows the deflection angle 2 α to be set. In this case, according to the invention, at least one of the disks 26 is rotatably mounted on the axis 25 in order to adapt the shape of the peripheral surface of the deflection mandrel 12 to the angle α. The rods 22 are fastened to the disks 26 via articulated connections.

Zweckmäßigerweise kann in diesem Fall eine der auf der Achse 25 verdrehbaren Scheiben 26 derart mechanisch mit der Wickelscheibe 3 verbunden sein, daß bei Verschwenken des Umlenkdornes 12 zum Einstellen des Winkels α eine automatische Verdrehung der Scheibe 26 relativ zu der anderen Scheibe 26 erfolgt. Hierdurch wird vorteilhafterweise die Ausbildung des Umlenkdornes 12 selbsttätig an den jeweils ein­gestellten Winkel α angepaßt.In this case, one of the disks 26 rotatable on the axis 25 can expediently be mechanically connected to the winding disk 3 such that when the deflection mandrel 12 is pivoted to adjust the angle α, the disk 26 is automatically rotated relative to the other disk 26. As a result, the design of the deflection mandrel 12 is advantageously adapted automatically to the respectively set angle α.

In Fig. 5 ist das den Umlenkdorn 12 umschlingende bandförmige Material 6 sowie dessen Längsachse 21 durch Strichpunktlinien angedeutet. Hieraus wird deutlich, daß der Winkel 27 zwischen jeder jeweils eine Berührungsgerade darstellenden Stange 22 und der Bandlängsachse 21 90° beträgt, das bandförmige Material 6 aber dennoch um den Winkel 2 α umgelenkt wird.5, the band-shaped material 6 wrapping around the deflecting mandrel 12 and its longitudinal axis 21 are indicated by dash-dot lines. This becomes it is clear that the angle 27 between each rod 22 each representing a line of contact and the longitudinal axis 21 of the strip is 90 °, but the strip-shaped material 6 is nevertheless deflected by the angle 2 α.

Neben der beschriebenen vorteilhaften Ausbildung des Umlenkdornes 12 liegt es im Rahmen der Erfindung, diesen aus einem massiven Vollmaterial oder mit einer vollflächigen Umfangsfläche auszubilden, die dann an einen bestimmten Winkel α angepaßt ist.In addition to the described advantageous embodiment of the deflection mandrel 12, it is within the scope of the invention to form it from a solid solid material or with a full-surface circumferential surface which is then adapted to a certain angle α.
