Abstract

The invention relates to a device for the helical taping of circular tubes (4) with smooth, uncorrugated tape (8), which is drawn off from a tape roll (7) by the rotating tube (4) and deformed by a rolling process immediately before it is applied to the tube (4). The rolling process is brought about by a rolling ring (12), driven synchronously with the tube (4) by the tube's (4) rotary drive unit and surrounding the tube (4), and a frictionally driven rolling plate (13), whose circumferential surface can be adjusted about an axis lying at a transverse angle to the tube's longitudinal axis (4a) and fed in to the rolling ring (12). The rolling ring (12) and the rolling plate (13) with its adjusting device are located on a rotary table (10) which, according to the particular inclination of the tape (8) being wound can be rotated about an axis (17) intersecting the longitudinal axis (4a) of the tube at right angles as an extension of the lead point (16) of the tape (8) onto the tube (4). Also located on the rotary table (10) is a slotting tool (20) whose cutting edge (20a) engages on the tube (4) roughly 90<o> in front of the lead point (16) of the tape (8) onto the tube (4). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum wendelförmigen Bewickeln von Rohren kreisförmigen Querschnitts mit glattem, ungewellten Band, welches durch das sich drehende Rohr von einer Bandrolle abgezogen und unmittelbar vor dem Aufbringen auf das Rohr durch einen Walzvorgang verformt wird, der durch einen synchron mit dem Rohr vom Drehantrieb des Rohres angetriebenen, das Rohr umgebenden Walzring und einen reibschlüssig mitlaufenden Walzteller bewirkt wird, dessen Umfangsfläche um eine quer zur Rohrlängsachse liegende Achse anstellbar und gegenüber dem Walzring zustellbar gelagert ist.The invention relates to a device for helically winding pipes of circular cross-section with smooth, non-corrugated tape, which is drawn off by the rotating tube from a roll of tape and is deformed immediately before application to the tube by a rolling process, which by a synchronous with the tube from Rotary drive of the tube driven, surrounding the tube ring and a frictionally co-rotating roller plate is effected, the circumferential surface of which is adjustable about an axis lying transversely to the longitudinal axis of the tube and is supported such that it can be delivered relative to the roller ring.

Eine Vorrichtung der voranstehend beschriebenen Art ist aus der DE-A-31 31 473 bekannt. Bei dieser Vorrichtung ist die Walzfläche des Walzringes in einer rechtwinklig zur Rohrlängsachse verlaufenden Ebene angeordnet, weil der Walzring das Rohr konzentrisch umgibt. Hierdurch ergibt sich zwar eine einfache Ableitung des Walzringantriebes vom Drehantrieb des Rohres. Das zwischen dem Walzring und dem Walzteller durch einen Walzvorgang verformte Band wird jedoch unabhängig von der jeweiligen Steigung der auf dem Rohr anzubringenden Bandwendel rechtwinklig zur Rohrlängsachse aufgebracht, so daß es anschließend durch entsprechende Führungen in die mit der jeweiligen Steigung übereinstimmende Lage auf dem Rohr gebracht werden muß.A device of the type described above is known from DE-A-31 31 473. In this device, the rolling surface of the rolling ring is arranged in a plane running at right angles to the longitudinal axis of the pipe, because the rolling ring concentrically surrounds the pipe. This does indeed result in a simple derivation of the rolling ring drive from the rotary drive of the tube. The strip deformed by a rolling process between the rolling ring and the rolling plate is, however, applied at right angles to the longitudinal axis of the tube, regardless of the respective pitch of the coil to be attached to the tube, so that it is then brought into the position on the tube corresponding to the respective pitch by appropriate guides got to.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zum wendelförmigen Bewickeln von Rohren kreisförmigen Querschnitts mit glattem, ungewellten Band derart weiterzubilden, daß das auf das Rohr aufzubringende Band in Übereinstimmung mit dem jeweiligen Steigungswinkel dem Rohr zugeführt und hierbei einem Walzvorgang zwischen Walzring und Walzteller unterworfen wird, so daß nachträgliche Verlagerungen oder Verformungen des aufgewickelten Bandes vermieden werden, die nicht nur eine zusätzliche Verformungsenergie benötigen, sondern auch zusätzliche Belastungen des Bandes darstellen und zu einer Begrenzung der Wickelgeschwindigkeit führen.The invention has for its object to develop a device of the type described above for helically winding pipes of circular cross-section with a smooth, non-corrugated band such that the band to be applied to the pipe is fed to the pipe in accordance with the respective pitch angle and thereby a rolling process between the rolling ring and roller plate is subjected, so that subsequent displacements or deformations of the wound tape are avoided, which not only require additional deformation energy, but also represent additional loads on the tape and lead to a limitation of the winding speed.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß der Walzring und der Walzteller mit seiner Verstelleinrichtung auf einem Drehtisch angeordnet sind, der entsprechend der jeweiligen Steigung des aufzuwickelnden Bandes um eine die Rohrlängsachse in Verlängerung des Auflaufpunktes des Bandes auf das Rohr rechtwinklig schneidende Achse verdrehbar ist.The solution to this problem by the invention is characterized in that the roller ring and the roller plate with its adjusting device are arranged on a rotary table which, according to the respective pitch of the strip to be wound, about an axis which cuts the pipe longitudinal axis in the extension of the point of impact of the strip onto the pipe at right angles is rotatable.

Mit dieser erfindungsgemäßen Weiterbildung wird erreicht, daß das Band bereits unter demjenigen Winkel auf die Rohroberfläche aufgezogen und zugleich einem Walzvorgang unterworfen wird, der dem jeweiligen Steigungswinkel entspricht. Hierdurch entfallen nachträgliche Verformungen bzw. Lageveränderungen des Bandes auf der Rohroberfläche, die neben einer zusätzlichen Belastung insbesondere zu einer Begrenzung der Wickelgeschwindigkeit geführt haben. Der Aufwickelvorgang wird somit sowohl hinsichtlich der Belastung der Führungseinrichtungen für das Band als auch hinsichtlich der Belastungen des Bandes derart verbessert, daß geringerwertiges Band mit höherer Wickelgeschwindigkeit aufgebracht werden kann und der Verschleiß der Führungseinrichtungen herabgesetzt wird.With this development according to the invention it is achieved that the strip is already drawn onto the pipe surface at that angle and at the same time subjected to a rolling process which corresponds to the respective pitch angle. This eliminates subsequent deformations or changes in position of the strip on the pipe surface, which in addition to an additional load have in particular limited the winding speed. The winding process is thus improved both with regard to the load on the guide devices for the tape and with regard to the loads on the tape in such a way that low-quality tape can be applied at a higher winding speed and the wear on the guide devices is reduced.

Die erfindungsgemäße Weiterbildung der bekannten Vorrichtung schafft darüber hinaus die Möglichkeit, daß gemäß einem weiteren Merkmal der Erfindung am Drehtisch ein Nutwerkzeug angeordnet werden kann, dessen Schneide im Bereich von etwa 90° vor dem Auflaufpunkt des Bandes auf das Rohr am Rohr angreift. Durch diese erfindungsgemäße Ausrichtung des Nutwerkzeuges entsprechend der jeweiligen Steigung des Bandes und durch das Entstehen der Nut kurz vor dem Auflaufpunkt des Bandes wird erreicht, daß das Band zuverlässig in die kurz zuvor hergestellte Nut in der Oberfläche des Rohres einläuft, und zwar unabhängig von in der Praxis unvermeidbaren Gleichlaufschwankungen sowohl hinsichtlich des Drehantriebes als auch hinsichtlich des Rohrvorschubes.The development of the known device according to the invention also creates the possibility that, according to a further feature of the invention, a grooving tool can be arranged on the rotary table, the cutting edge of which engages the tube on the tube in the region of approximately 90 ° before the point of impact of the strip. This orientation of the grooving tool according to the invention in accordance with the respective slope of the band and by the formation of the groove shortly before the point of impact of the band ensures that the band reliably runs into the groove previously produced in the surface of the tube, independently of in the Practice unavoidable synchronism fluctuations both with regard to the rotary drive and with regard to the pipe feed.

Mit der Erfindung wird schließlich vorgeschlagen, dem Nutwerkzeug einen Nutzudrücker- und eine Rippenrichtführung nachzuschalten, wobei der Nutzudrücker innerhalb einer halben Umdrehung des Rohres nach dem Auflaufpunkt des Bandes angeordnet ist, so daß mit der erfindungsgemäßen Vorrichtung ein einwandfreier und fester Sitz des Bandes im genuteten Rohr garantiert werden kann.Finally, with the invention it is proposed to connect the utility tool with a utility lever and a fin directional guide, the utility lever being arranged within half a revolution of the tube after the point of impact of the tape, so that with the device according to the invention the tape is properly and firmly seated in the grooved tube can be guaranteed.

Auf der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung dargestellt, und zwar zeigen:

  • Fig. 1 eine Draufsicht auf eine schematische Gesamtdarstellung der Vorrichtung,
  • Fig. 2 eine Draufsicht auf den Drehtisch,
  • Fig. 3 eine Stirnansicht des Drehtisches,
  • Fig. 4 eine Seitenansicht des Drehtisches und
  • Fig. 5 eine perspektivische Ansicht des Aufwikkelbereiches.
An exemplary embodiment of the device according to the invention is shown in the drawing, namely:
  • 1 is a plan view of an overall schematic representation of the device,
  • 2 is a plan view of the turntable,
  • 3 is an end view of the turntable,
  • Fig. 4 is a side view of the turntable and
  • Fig. 5 is a perspective view of the winding area.

Die Draufsicht in Fig. 1 zeigt ein Maschinenbett 1, auf dem ein Dreh- und Vorschubantrieb 2 mit einer Mitnahmevorrichtung 3 für das Rohr 4 angeordnet ist. Das zu bewickelnde Rohr 4 wird somit drehend und mit einem der Steigung des aufzuwickelnden Bandes entsprechenden Vortrieb angetrieben. Auf einer Lagerplatte 5 ist weiterhin eine Lünette 6 zur Abstützung des bewickelten Rohres 4 angeordnet. Außerdem zeigt die Fig. 1 eine Bandrolle 7, von der das aufzuwickelnde Band 8 durch das sich drehende Rohr 4 abgezogen wird.The top view in FIG. 1 shows a machine bed 1, on which a rotary and feed drive 2 with a driving device 3 for the tube 4 is arranged. The pipe 4 to be wound is thus driven in rotation and with a propulsion corresponding to the pitch of the band to be wound. A steady rest 6 for supporting the wound tube 4 is also arranged on a bearing plate 5. 1 also shows a tape reel 7, from which the tape 8 to be wound is drawn off by the rotating tube 4.

Dieses Band 8 wird über eine Umlenkrolle 9 einer Aufwickelvorrichtung zugeführt, die in Fig. 1 nur in einer schematischen Draufsicht und in den Figuren 2 bis 5 anhand eines Ausführungsbeispiels dargestellt ist. Diese Aufwickelvorrichtung umfaßt einen Drehtisch 10, der um eine senkrechte Achse gegenüber dem Maschinenbett 1 verdrehbar ist, wie dies übertrieben in Fig. 1 gezeichnet wurde. Dieser Drehtisch 10 trägt einen Lagerbock 11 für einen Walzring 12, der das zu bewickelnde Rohr 4 umgibt und mit dem ein Walzteller 13 zusammenwirkt. Während der Walzring 12 synchron mit dem Rohr 4 vom Dreh- und Vorschubantrieb 2 angetrieben ist, wird der Walzteller 13 kraftschlüssig vom Walzring 12 mitgenommen. Um den zwischen Walzring und Walzteller stattfindenden Walzvorgang für das aufzuwickelnde Band 8 einstellen zu können, ist der Walzteller 13 um eine waagerechte Achse anstellbar und gegenüber dem Walzring zustellbar auf dem Drehtisch 10 gelagert. Der jeweilige Anstellwinkel des Drehtisches 10 gegenüber der Längsachse des Rohres 4, der der jeweiligen Steigung des auf das Rohr 4 aufzuwickelnden Bandes 8 entspricht, ist an einem Skalenring 14 am Drehtisch 10 ablesbar.This belt 8 is fed via a deflecting roller 9 to a winding device, which is shown in FIG. 1 only in a schematic plan view and in FIGS. 2 to 5 using an exemplary embodiment. This winding device comprises a turntable 10 which can be rotated about a vertical axis relative to the machine bed 1, as exaggerated in FIG. 1 was drawn. This turntable 10 carries a bearing block 11 for a rolling ring 12 which surrounds the tube 4 to be wound and with which a roller plate 13 cooperates. While the rolling ring 12 is driven synchronously with the tube 4 by the rotary and feed drive 2, the rolling plate 13 is frictionally carried along by the rolling ring 12. In order to be able to set the rolling process for the strip 8 to be wound between the rolling ring and the rolling plate, the rolling plate 13 can be adjusted about a horizontal axis and is supported on the turntable 10 so that it can be delivered relative to the rolling ring. The respective angle of attack of the rotary table 10 with respect to the longitudinal axis of the tube 4, which corresponds to the respective slope of the band 8 to be wound onto the tube 4, can be read off on a scale ring 14 on the rotary table 10.

Der Drehtisch 10 und die auf ihm angeordneten Bauteile sind in den Figuren 2 bis 5 im einzelnen dargestellt. Diese detaillierteren Darstellungen zeigen eine Bandführung 15 für das dem drehenden Rohr 4 zuzuführende Band 8, die entsprechend dem eingestellten Winkel des Drehtisches 10 zur Längsachse des Rohres 4 ausgerichtet ist. Mit Hilfe dieser Bandführung 15 wird das Band 8 beim dargestellten Ausführungsbeispiel der Unterseite des Rohres 4 zugeführt, und zwar entsprechend dem jeweiligen Steigungswinkel des Bandes 8 auf der Oberfläche des Rohres 4. Der Auflaufpunkt 16 des Bandes 8 auf das Rohr 4 ist in den Figuren 2 bis 5 eingezeichnet. Durch diesen Auflaufpunkt 16 verläuft die Achse 17 des Drehtisches 10 gegenüber dem Maschinenbett 1, die beim Ausführungsbeispiel durch einen Lagerbolzen 18 gebildet wird und die senkrecht verlaufend die Längsachse des Rohres 4 in Verlängerung des Auflaufpunktes 16 schneidet. Hierdurch wird sichergestellt, daß der vom Walzring 12 und Walzteller 13 auf das Band ausgeübte Walzvorgang exakt im Auflaufpunkt 16 stattfindet, und zwar unabhängig vom jeweils eingestellten Winkel des Drehtisches 10 gegenüber dem Maschinenbett 1 und unabhängig vom Anstellwinkel des Walztellers 13 gegenüber dem Walzring 12, der durch Verschwenken des Walztellers 13 um die in Fig. 4 eingezeichnete Schwenkachse 19 stattfindet.The turntable 10 and the components arranged on it are shown in detail in FIGS. 2 to 5. These more detailed representations show a band guide 15 for the band 8 to be fed to the rotating tube 4, which is aligned according to the set angle of the rotary table 10 to the longitudinal axis of the tube 4. With the aid of this band guide 15, the band 8 in the illustrated embodiment is fed to the underside of the tube 4, in accordance with the respective pitch angle of the band 8 on the surface of the tube 4. The point of contact 16 of the band 8 on the tube 4 is shown in FIGS. 2 drawn to 5. The axis 17 of the turntable 10 runs through this run-up point 16 with respect to the machine bed 1, which in the exemplary embodiment is formed by a bearing pin 18 and which intersects the longitudinal axis of the tube 4 in an extension of the run-up point 16. This ensures that the rolling process exerted by the rolling ring 12 and rolling plate 13 on the strip takes place exactly at the run-up point 16, regardless of the angle of the turntable 10 relative to the machine bed 1 and regardless of the angle of attack of the rolling plate 13 relative to the rolling ring 12 by pivoting the roller plate 13 about the pivot axis 19 shown in FIG. 4.

Aufgrund der voranstehend beschriebenen Einstellmöglichkeit wird sichergestellt, daß das Band 8 mittels der Bandführung 15 stets unter demjenigen Winkel der Oberfläche des Rohres 4 zugeführt wird, der dem jeweiligen Steigungswinkel des Bandes 8 auf dem Rohr 4 entspricht. Außerdem ermöglicht diese Einstellmöglichkeit ein Nuten der Rohroberfläche und ein zuverlässiges Einführen des aufzuwickelnden Bandes 8 in diese Nut, um einerseits einen zuverlässigen Sitz des aufgewickelten Bandes 8 auf dem Rohr 4 zu garantieren und andererseits einen guten Wärmeübergang zwischen aufgewickeltem Band 8 und Rohr 4 zu erzeugen.The setting option described above ensures that the band 8 is always fed by means of the band guide 15 at the angle of the surface of the tube 4 which corresponds to the respective pitch angle of the band 8 on the tube 4. In addition, this setting option enables the pipe surface to be grooved and the band 8 to be wound up to be reliably introduced into this groove, on the one hand to guarantee a reliable fit of the coiled band 8 on the pipe 4 and on the other hand to produce good heat transfer between the wound band 8 and the pipe 4.

Das Nuten des Rohres 4 erfolgt mit Hilfe eines Nutwerkzeuges 20, das ausricht- und zustellbar am Lagerbock 11 des Walzringes 12 angeordnet ist und dessen Schneide 20a im Bereich von etwa 90° vor dem Auflaufpunkt 16 am Rohr 4 angreift. Das sich in Fig. 3 entgegengesetzt zum Uhrzeigersinn drehende Rohr 4 wird demzufolge etwa 1/4 Umdrehung vor dem Auflaufpunkt 16 durch die Schneide 20a des Nutwerkzeugs 20 mit der wendelförmig verlaufenden Nut versehen, so daß auch bei Gleichlaufschwankungen hinsichtlich des Drehantriebes und des Vorschubes des Rohres 4 gewährleistet ist, daß das Band 8 stets zuverlässig in die zuvor hergestellte Nut einläuft.The pipe 4 is grooved with the aid of a grooving tool 20 which is arranged on the bearing block 11 of the rolling ring 12 in an alignable and deliverable manner and whose cutting edge 20a engages the pipe 4 in the region of approximately 90 ° before the point of impact 16. The tube 4 rotating counterclockwise in FIG. 3 is consequently provided with the helical groove about 1/4 turn before the run-up point 16 by the cutting edge 20a of the grooving tool 20, so that even in the event of synchronous fluctuations with regard to the rotary drive and the feed of the tube 4 ensures that the band 8 always reliably runs into the previously prepared groove.

Zusätzlich zum Nutwerkzeug 20 ist am Lagerbock 11 ein Nutzudrücker 21 angeordnet, der auf die ungenutete Oberfläche des Rohres 4 wirkt und eine Art Verstemmung des in die Nut eingezogenen Bandfußes bewirkt. Außerdem zeigen die Figuren 4 bis 5 eine Rippenrichtführung 22, die evenuell auftretende Verformungen der auf dem Rohr 4 befindlichen Rippen korrigiert. Der besseren Übersichtlichkeit wegen sind Nutwerkzeug 20, Nutzudrücker 21 und Rippenrichtführung 22 in der Draufsicht in Fig. 2 weggelassen worden.In addition to the grooving tool 20, a useful lever 21 is arranged on the bearing block 11, which acts on the non-grooved surface of the tube 4 and causes a kind of caulking of the band foot drawn into the groove. FIGS. 4 to 5 also show a fin guide 22 which corrects any deformations of the fins on the tube 4. For the sake of clarity, grooving tool 20, utility lever 21 and rib direction guide 22 have been omitted from the top view in FIG. 2.

Die perspektivische Darstellung in Fig. 5 zeigt nochmals das Zusammenwirken der einzelnen Teile beim Nuten und Aufwickeln des Bandes 8 auf dem Rohr 4. Das im Auflaufpunkt 16 dem Rohr 4 an der Unterseite durch die Bandführung 15 zugeführte Band 8 läuft an diesem Auflaufpunkt 16 in die Nut ein, die etwa eine halbe Umdrehung vor dem Auflaufpunkt 16 durch die Schneide 20a des Nutwerkzeugs 20 erzeugt worden ist. Der besseren Übersichtlichkeit wegen sind die bereits aufgewickelten Windungen des Bandes 8 auf der Zeichnung in Fig. 5 nicht dargestellt. Hierdurch ist der auf die ungenutete Oberfläche des Rohres 4 wirkende Nutzudrücker 21 zu erkennen, des leichen die Rippenrichtführung 22, die vorzugsweise an der oberen Hälfte der aufgewickelten Rippe angreift. Außerdem zeigt die Perspektive das Zusammenwirken zwischen Walzring 12 und Umfangsfläche des Walztellers 13 sowie den Winkel 23 zwischen der Längsachse 4a des Rohres 4 und der Längsachse 10a des gegenüber dem Maschinenbett 1 verdrehten Drehtellers 10.The perspective view in FIG. 5 again shows the interaction of the individual parts when grooving and winding the tape 8 on the tube 4. The tape 8 fed to the tube 4 on the underside through the tape guide 15 at the run-up point 16 runs into the run-up point 16 in the run-up point 16 Groove that has been created about half a turn before the point of impact 16 by the cutting edge 20a of the grooving tool 20. For the sake of clarity, the windings of the band 8 that have already been wound are not shown in the drawing in FIG. 5. In this way, the usable pusher 21 acting on the non-grooved surface of the tube 4 can be seen, the corpus guide 22, which preferably engages the upper half of the wound rib. In addition, the perspective shows the interaction between the rolling ring 12 and the circumferential surface of the rolling plate 13 and the angle 23 between the longitudinal axis 4a of the tube 4 and the longitudinal axis 10a of the turntable 10 rotated relative to the machine bed 1.

Claims (3)

1. A device whereby tubes of circular cross- section are helically wrapped in a helix with smooth uncorrugated tape (8) which is drawn from a roll (7) by the rotating tube (4) and immediately before being wound on the tube, is deformed by rolling by a collar (12) which surrounds the tube (4) and is driven by the tube- rotating drive in synchronism with the tube, and also by a plate (13) which rotates in frictional engagement with the collar and the peripheral surface of which is mounted so as to be adjustable relative to the collar (12) and around an axis (17) transversely to the longitudinal axis (4a) of the tube,
characterised in that the collar (12), the plate (13) and the means for adjusting it are disposed on a turntable (10) which, corresponding to the pitch of the tape (8) for wrapping, is rotatable around an axis (17) which intersects the longitudinal axis (4a) of the tube at right angles and is in line with the place (16) where the tape (8) runs on to the tube (4).
2. A device according to claim 1, characterised in that a slotting tool (20) is disposed on the turntable (10) and has a blade (20a) which engages the tube (4) at about 90° before the place (16) where the tape (8) runs onto the tube (4).
3. A device according to claims 1 and 2, characterised in that the slotting tool (20) is followed by a slot compressor (21) and a rib guide (22).
