Abstract
Description
Die Erfindung betrifft eine Bandagiermaschine zum Umwickeln von langgestreckten Produkten, wie Schläuche, Kabel oder Rohre, 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 gelagerten Wickeltrommel für das bandförmige Material sowie mit einem auf der Wickelscheibe angeordneten Umlenkdorn, wobei zur Umlenkung des bandförmigen Materials in Richtung des zu umwickelnden Produktes die Längsachse des Umlenkdorns einen Winkel α mit der Drehachse der Wickeltrommel einschließt.The invention relates to a bandaging machine for wrapping elongated products, such as hoses, cables or pipes, with a band-shaped material, with a winding disc which can be driven in rotation about an axis of rotation perpendicular to the disc surface and an opening aligned with the axis of rotation for carrying the elongated product in 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 deflecting mandrel arranged on the winding disc, the longitudinal axis of the deflecting mandrel uniting to deflect the band-shaped material in the direction of the product to be wrapped Includes angle α with the axis of rotation of the winding drum.
Bei derartigen Bandagiermaschinen ist durch die parallele Anordnung der Drehachsen der Wickelscheibe und der Wickeltrommel mindestens ein Umlenkdorn erforderlich, der das bandförmige Material aufgrund seiner Ausrichtung (Winkel α zur Drehachse der Wickeltrommel) um einen Winkel 2α in Richtung des zu umwickelnden Produktes umlenkt. Der Umlenkdorn ist hierzu üblicherweise 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 aber 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 Wickelscheibendrehzahlung 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, the parallel arrangement of the axes of rotation of the winding disk and the winding drum requires at least one deflecting mandrel which deflects the band-shaped material by an angle 2α due to its orientation (angle α to the axis of rotation of the winding drum) in the direction of the product to be wrapped. For this purpose, the deflection mandrel is usually designed as a cylindrical pin, which is on the winding disk in the desired position Angle arrangement is rigidly attached so that the band-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, there is 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 achieves a maximum winding speed of 200 revolutions 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.
Eine spezielle Bandagiermaschine der gattungsgemäßen Art ist aus der DE-B-1 013 343 bekannt. Dieses Dokument beschreibt einen "Bandwickler" mit drei zur Drehachse eines Wickelkopfes parallelen Lagerbolzen, auf denen jeweils drei, d.h. folglich insgesamt neun, Bandrollen gelagert sind. Zur Führung und Umlenkung jedes Bandes dienen zylindrische Stifte, wobei das jeweilige Band - ausgehend von der jeweiligen Bandrolle - zunächst durch zwei parallel zur Bandrollenachse liegende Stifte, dann über einen mit der Bandrollenebene einen Winkel von 45° bzw. 135° einschließenden Umlenkstift und schließlich über einen parallel zur Bandrollenebene gerichteten Stift (Abb. 1 bis 6) bzw. über einen parallel zu dem von dem erstgenannten Umlenkstift ablaufenden Bandteil liegenden, zweiten Umlenkstift (Abb. 7 bis 9) geführt ist. Die gegenseitige Anordnung der Stifte ist so, daß der auf den erstgenannten Umlenkstift auflaufende Bandteil und der von diesem ablaufende, umgelenkte Bandteil in zwei zueinander und zur Achse des zu umwickelnden Produktes (Kabels) parallelen Ebenen liegen. Hierdurch soll aber insbesondere ein geringstmöglicher Abstand der Bandrollen von dem zu umwickelnden Produkt (Kabel) erreicht werden. Ferner soll das Anlegen der Bänder an das Kabel erleichtert werden. Da alle bei diesem bekannten Bandwickler vorgesehenen Umlenkstifte zylindrisch ausgebildet sind, treten hier ebenfalls die oben bereits geschilderten Probleme auf.A special bandaging machine of the generic type is known from DE-B-1 013 343. This document describes a "tape winder" with three to the axis of rotation of a winding head parallel bearing bolts, on each of which three, ie consequently a total of nine, belt rolls are mounted. Cylindrical pins are used for guiding and deflecting each band, whereby the respective band - starting from the respective band reel - first through two pins lying parallel to the band reel axis, then via a deflection pin enclosing an angle of 45 ° or 135 ° with the band reel plane and finally over a pin directed parallel to the band reel plane (Figs. 1 to 6) or via a second deflection pin (Fig. 7 to 9) lying parallel to the band part running from the first-mentioned deflection pin. The mutual arrangement of the pins is such that the band part running onto the first-mentioned deflection pin and the part of the band diverted from it run in two planes parallel to one another and to the axis of the product (cable) to be wrapped. In this way, however, the smallest possible distance between the tape rolls and the product to be wrapped (cable) is to be achieved. Furthermore, the application of the tapes to the cable should be made easier. Since all the deflection pins provided in this known tape winder are cylindrical, the problems already described above also occur here.
Bei einer aus der US-A-3 099 190 bekannten "Streifen-Wickelvorrichtung" ist kein Umlenkdorn im Sinne der vorliegenden Erfindung beschrieben, sondern vielmehr eine "Umlenkeinrichtung" (Wickelführung) aus mehreren Rollen, die sich zwischen zwei Scheiben etwa in Längsrichtung des zu umwikkelnden Produktes erstrecken und dabei auf einem das Produkt etwa zur Hälfte umschließenden Halbkreis bzw. Halbzylinder liegend "hintereinanderher" um das Produkt herumgeführt werden. Dabei sind die einzelnen Rollen jeweils derart winklig zueinander angeordnet, daß hier zwischen den einzelnen Rollen und dem bandförmigen Material jeweils Berührungsgeraden gebildet sind, die senkrecht zur Bandlängsachse angeordnet sind. Allerdings bedingt diese spezielle Ausgestaltung der "Umlenkeinrichtung", daß die das bandförmige Material enthaltende Wickeltrommel das Produkt konzentrisch umschließend zusammen mit der Umlenkeinrichtung rotiert, was im Vergleich zu einer "neben" dem zu umwickelnden Produkt um eine parallele Achse drehbar gelagerten Wickeltrommel wesentliche Nachteile bei einem Auswechseln der Trommel verursacht.In a "strip winding device" known from US-A-3 099 190, no deflecting mandrel in the sense of the present invention is described, but rather a "deflecting device" (winding guide) comprising a plurality of rollers, which extend between two disks approximately in the longitudinal direction of the extend around the product and, while lying on a semicircle or half cylinder enclosing the product about half, are guided "one after the other" around the product. The individual roles are each arranged at an angle to each other that here between the individual roles and the band-shaped material are each formed straight lines of contact which are arranged perpendicular to the longitudinal axis of the band. However, this special design of the "deflection device" means that the winding drum containing the band-shaped material rotates the product concentrically around the deflecting device, which compared to a "besides" the product to be wrapped around a parallel axis rotatably mounted winding drum with a significant disadvantage Replacement of the drum caused.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Bandagiermaschine der eingangs beschriebenen, gattungsgemäßen Art derart zu verbessern, daß auch zug- bzw. reißempfindliche Materialien mit hohen Wickelgeschwindigkeiten verarbeitet werden können.The object of the present invention is to improve the bandaging machine of the generic type described at the outset in such a way that materials sensitive to tension 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 diaboloartig doppelkonisch ausgebildet ist, daß bei Umschlingung des Umlenkdorns durch das bandförmige Material sowohl am Anfang als auch am Ende der Umschlingung jeweils eine Berührungsgerade zwischen der Umfangsfläche des Umlenkdornes und dem bandförmigen Material gebildet ist, die ebenso wie alle zu diesen Berührungsgeraden parallel auf der Oberfläche des bandförmigen Materials 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.According to the invention this is achieved in that the deflecting mandrel is designed in a diabolo-like manner depending on the angle α such that when the deflecting mandrel is wrapped through the band-shaped material, a straight line of contact between the circumferential surface of the deflecting mandrel and the band-shaped both at the beginning and at the end of the wrapping Material is formed, which, like all of these straight lines of contact parallel to the surface of the band-shaped material, are arranged perpendicular to the longitudinal axis of the band, the circumferential surface of the deflecting mandrel being drivable such that the relative speed between the circumferential surface and the band-shaped material is zero.
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 wirkende 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.On the one hand, this advantageous embodiment eliminates the friction between the deflecting mandrel and the band-shaped material, so that the winding process is much less Tensile forces 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.
Weitere vorteilhafte Ausgestaltungsdmerkmale sind in den Unteransprüchen enthalten.Further advantageous design features 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
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
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
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
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
Erfindungsgemäß ist nun der Umlenkdorn 12 (Fig. 3 bis 5) derart in Abhängigkeit von dem Winkel α diaboloförmig doppelkonisch 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 double-cone shape depending on the angle α in such a way that when the
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
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
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
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.
