Description

Die Erfindung betrifft eine Vorrichtung zum Abwickeln einer Materialbahn von einer Rolle mit zwei quer zur Bahn in Abstand voneinander hochschwenkbar gelagerten Tragarmen, die Mittel zum Aufnehmen und drehbaren Halten der Rolle aufweisen.The invention relates to a device for unwinding a web of material from a roll with two support arms which are mounted so that they can be swiveled up at a distance from one another transversely to the web and which have means for receiving and rotatably holding the roll.

Vorrichtungen dieser Art dienen insbesondere zum Abrollen von Papierbahnen in der papierverarbeitenden Industrie.Devices of this type are used in particular for unrolling paper webs in the paper processing industry.

Die abzuwickelnde Papierrolle wird zwischen den Tragarmen eingehängt und zum Abwickeln angehoben. Beim achslosen Abwickeln einer auf eine Hülse aufgewickelten Papierbahn werden dazu zwei an den Tragarmen drehbar befestigte Spannköpfe in die beiden seitlichen Öffnungen der Wickelhülse eingefahren. Derartige Abwickelvorrichtungen sind z.B. in dem DE-GM 85 11 986 und in der DE-OS 29 51 336 beschrieben.The paper roll to be unwound is suspended between the support arms and raised for unwinding. When unwinding a paper web wound onto a tube, two clamping heads rotatably fastened to the support arms are inserted into the two lateral openings of the winding tube. Such unwinding devices are described for example in DE-GM 85 11 986 and in DE-OS 29 51 336.

Üblicherweise erfolgt die Zufuhr einer neuen Rolle zum Rollenwechsel auf Unterflurförderern, die die Rolle in den Aufnahmebereich der Spannköpfe fördern, die zur Aufnahme einer Rolle auseinander und nach unten gefahren werden können. Bei mehreren, in Bahnlaufrichtung hintereinander angeordneten Abrollungen ist es für einen schnellen Rollenwechsel vorteilhaft, die neuen Rollen von der Seite, quer zur Bahnlaufrichtung zuzuführen. Bei Vorrichtungen mit in seitlichen Ständern befestigten Tragarmen muß dazu zwischen den Abrollstationen Platz gelassen werden, da die Ständer einer seitlichen Beschickung im Wege stehen, und es ist eine zusätzliche Förderung in Bahnlaufrichtung erforderlich, der die Rolle in die Aufnahmeposition der Spannköpfe bringt.Usually, a new roll for changing rolls is fed on underfloor conveyors which convey the roll into the receiving area of the clamping heads, which can be moved apart and down to receive a roll. If there are several unwinds arranged one behind the other in the web running direction, it is advantageous for a quick roll change to feed the new rolls from the side, transversely to the web running direction. In devices with support arms attached in side stands, space must be left between the unwinding stations because the stands stand in the way of a side loading, and an additional conveying in the direction of web travel is required, which brings the roll into the receiving position of the clamping heads.

Um diesen zusätzliche Förderung zu vermeiden und um einen platzsparenderen Aufbau zu erreichen, sind in der gattungsgemäßen Vorrichtung nach dem DE-GM 85 11 986 die in einem Gestell aufgehängten Tragbalken an der Beschickungsseite zum Einfahren einer neuen Rolle hochschwenkbar. Die Tragbalken schwenken zur Aufnahme einer neuen Rolle in eine vertikale Stellung, anschließend wird durch Verkürzung der Tragarme die Rolle angehoben. An dieser Vorrichtung ist nachteilig, daß alle Kräfte von horizontalen Trägern des Gestells übertragen werden, das daher aus Stabilitätsgründen sehr schwer ausgeführt sein muß.In order to avoid this additional funding and to achieve a more space-saving structure, the supporting beams suspended in a frame in the generic device according to DE-GM 85 11 986 can be swiveled up on the loading side for insertion of a new roll. The support beams swivel into a vertical position to accommodate a new roll, then the roll is raised by shortening the support arms. A disadvantage of this device is that all forces are transmitted by horizontal supports of the frame, which must therefore be made very difficult for reasons of stability.

Es sind auch bereits Vorrichtungen bekannt, bei denen die Tragarme an Ständern vertikal beweglich befestigt sind und zusätzlich zum Einfahren einer neuen Rolle hochgeschwenkt werden können. Zum Anheben in die Abwickelposition werden die in etwa waagerecht abstehenden Tragarme vertikal in den Ständern verfahren. Dies verlangt eine aufwendige senkrechte Führung der Tragarme in den seitlichen Ständern.Devices are also already known in which the support arms are fastened to stands in a vertically movable manner and can additionally be swiveled up in order to retract a new roll. To lift it into the unwinding position, the approximately horizontally projecting support arms are moved vertically in the stands. This requires complex vertical guidance of the support arms in the side stands.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, die konstruktiv einfach und platzsparend aufbaubar ist.The invention has for its object to provide a generic device that is structurally simple and space-saving.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Nach der Erfindung läßt sich das Hochheben der Rolle in die Abwickelposition durch eine Schwenkbewegung bewerkstelligen, so daß eine aufwendige vertikale Führung überflüssig ist. Gleichzeitig lassen sich die Rollenaufnahmeeinrichtungen an den Enden der Tragarme in horizontaler Richtung bewegen, so daß beim Rollenwechsel die neue Rolle nicht quer zu ihrer Achse positioniert werden muß. Dieses Prinzip ermöglicht so sowohl einen platzsparenden Aufbau, als auch eine vereinfachte Konstruktion, da die Tragarme beim Hochschwenken am Boden abgestützt werden können.According to the invention, the lifting of the roll into the unwinding position can be accomplished by a pivoting movement, so that an expensive vertical guide is unnecessary. At the same time, the roll receiving devices can be moved at the ends of the support arms in a horizontal direction, so that the new roll does not have to be positioned transversely to its axis when changing rolls. This principle enables both a space-saving structure and a simplified construction, since the support arms can be supported on the ground when swiveling up.

Als weiterer Vorteil tritt hinzu, daß sich die Tragarme in Abwickelposition in etwa senkrecht stellen lassen und so die an den Schwenkachsen wirkenden Drehmomente wesentlich verringert werden können. Bei einer nachträglichen axialen Korrektur der Abwickelposition werden so die Elemente, die ein Schwenken der Tragarme verhindern, erheblich weniger belastet.Another advantage is that the support arms can be set approximately vertically in the unwinding position and the torques acting on the swivel axes can be significantly reduced. In the event of a subsequent axial correction of the unwinding position, the elements which prevent the support arms from pivoting are thus subjected to considerably less stress.

Die Unteransprüche enthalten konstruktiv vorteilhafte Ausführungsformen der Erfindung.The subclaims contain constructively advantageous embodiments of the invention.

Während bei den Vorrichtungen nach den Ansprüchen 2 bis 6 die Horizontalbewegung der Schwenklager dadurch ermöglicht wird, daß die Tragarme hochschwenkbar in einer am Boden verfahrbaren Konstruktion gelagert sind, enthält der Patentanspruch 7 eine Ausführungsform, bei der die Tragarme an feststehenden Ständern über Hebel angelenkt sind.While in the devices according to claims 2 to 6, the horizontal movement of the pivot bearing is made possible by the fact that the support arms are pivotally mounted in a construction that can be moved on the ground, claim 7 contains an embodiment in which the support arms are articulated on fixed stands via levers.

Die in den Figuren 1 und 2 beschriebene erfindungsgemäße Vorrichtung ist auf zwei horizontalen Grundplatten 1, 2, die in einem Abstand größer als die maximale Rollenbreite voneinander angeordnet sind, quer zur Achse der abzuwickelnden Rolle 3 horizontal verfahrbar abgestützt, in Figur 2 von links nach rechts und umgekehrt.The device according to the invention described in Figures 1 and 2 is supported on two horizontal base plates 1, 2, which are arranged at a distance greater than the maximum roll width from each other, horizontally movable transversely to the axis of the roll 3 to be unwound, in Figure 2 from left to right and vice versa.

Sie weist zwei Tragarme 4, 5 mit einander zugewandten Spannköpfen 6, 7 zur Aufnahme einer Papierrolle 3 auf, wobei die Tragarme 4, 5 auf einer Welle 8 verschiebbar und durch eine Paßfeder 9 drehfest befestigt sind. Die Welle 8 weist an beiden Enden freilaufende Rollen 10, 11 auf, mit denen sie auf den Grundplatten 1, 2 hin- ­und hergefahren werden kann. Die Lager 12 der Welle 8 in den Rollen 10,11 sind zugleich die Schwenklager für die Schwenkbewegung der Tragarme 4,5. Der Antrieb für diese Bewegung befindet sich an einer Seite (in Fig. 1 rechts) auf der Grundplatte 2.It has two support arms 4, 5 with mutually facing clamping heads 6, 7 for receiving a paper roll 3, the support arms 4, 5 being displaceable on a shaft 8 and fixed in a rotationally fixed manner by a feather key 9. The shaft 8 has free-running rollers 10, 11 at both ends, with which it can be moved back and forth on the base plates 1, 2. The bearings 12 of the shaft 8 in the rollers 10, 11 are also the pivot bearings for the pivoting movement of the support arms 4, 5. The drive for this movement is located on one side (on the right in FIG. 1) on the base plate 2.

Er besteht aus einer Kolben-Zylinder-Einheit 13, die einerseits an der Grundplatte 2, andererseits an einem fahrbaren Wagen befestigt ist. Der Wagen baut sich aus zwei parallelen Seitenteilen 14, 15 auf, durch die an einem Ende die Welle 8 parallel zur Achse der Rolle 3 und frei drehbar geführt ist, so daß der Wagen auf der Welle 8 abgestützt ist. Das andere Ende des Wagens ist auf einer Rolle 16 abgestützt, die auf einer Welle 17 zwischen den beiden Seitenteilen 14, 15 sitzt und zwischen einer Führungsschiene 18 und der Grundplatte 2 läuft. Anstelle der Kolben-Zylinder-Einheit 13 kann als Antrieb ebenso ein Elektromotor mit Kette eingesetzt werden.It consists of a piston-cylinder unit 13 which is fastened on the one hand to the base plate 2 and on the other hand to a mobile carriage. The carriage is constructed from two parallel side parts 14, 15, through which the shaft 8 is guided at one end parallel to the axis of the roller 3 and freely rotatable, so that the carriage is supported on the shaft 8. The other end of the carriage is supported on a roller 16 which sits on a shaft 17 between the two side parts 14, 15 and runs between a guide rail 18 and the base plate 2. Instead of the piston-cylinder unit 13, an electric motor with a chain can also be used as the drive.

Damit die Vorrichtung auf beiden Seiten exakt gleich verfahren wird, enthält sie eine Gleichlaufvorrichtung. Diese besteht aus einer sich quer über die Arbeitsbreite erstreckenden Synchronwelle 19, die auf der Antriebsseite in dem Seitenteil 14 und auf der anderen Seite in einer am Ende der Welle 8 eingehängten Verbindungsplatte 20 drehbar gelagert ist. Auf beiden Enden der Synchronwelle 19 sind Ritzel 21, 22 befestigt, die jeweils in einer mit der jeweiligen Grundplatte 1, 2 verbundenen Zahnstange 23, 24 laufen. Am äußersten Ende der Synchronwelle 9 hinter der Verbindungsplatte 20 ist ein Rad 25 befestigt, das in einer Führungsschiene 26 mit U-förmigem Querschnitt läuft, um jederzeit den Eingriff des Ritzels 21 in die Zahnstange 23 sicherzustellen. Alternativ zu den Zahnstangen 23,24 können auch Triebstöcke oder Ketten eingesetzt werden.So that the device is moved exactly the same on both sides, it contains a synchronizing device. This consists of a synchronous shaft 19 extending across the working width, which is rotatably mounted on the drive side in the side part 14 and on the other side in a connecting plate 20 suspended at the end of the shaft 8. Pinions 21, 22 are fastened on both ends of the synchronous shaft 19 and each run in a toothed rack 23, 24 connected to the respective base plate 1, 2. At the extreme end of the synchronizing shaft 9 behind the connecting plate 20, a wheel 25 is fastened, which runs in a guide rail 26 with a U-shaped cross section in order to ensure the engagement of the pinion 21 in the rack 23 at all times. As an alternative to the toothed racks 23, 24, drive sticks or chains can also be used.

Anstelle nur eines Fahrantriebs mit einer Gleichlaufvorrichtung ist der Einsatz von zwei getrennten Antrieben an beiden Seiten möglich, wobei die Bewegung der beiden Antriebe aufeinander abgestimmt ist.Instead of only one travel drive with a synchronizing device, the use of two separate drives on both sides is possible, the movement of the two drives being coordinated with one another.

Zum Hoch- und Niederschwenken der Tragarme 4, 5 ist auf der Welle 8 im Bereich zwischen den beiden Seitenteilen 14, 15 ein Schwenkhebel 27 befestigt und mit einer Paßfeder 28 gegen Verdrehung gesichert. Am anderen Ende des Schwenkhebels 27 ist in einer Gabel eine Spindelmutter 29 um eine zur Welle 8 parallele Achse drehbar gelagert.For pivoting the support arms 4, 5 up and down, a pivot lever 27 is fastened on the shaft 8 in the area between the two side parts 14, 15 and secured against rotation with a feather key 28. At the other end of the pivot lever 27, a spindle nut 29 is rotatably mounted in a fork about an axis parallel to the shaft 8.

Durch die Spindelmutter 29 ist eine Gewindespindel 30 geführt, die von einem Getriebemotor 31 angetrieben wird, der an den Seitenteilen 14, 15 oberhalb der Rolle 16 drehbar befestigt ist. Mit dem Getriebemotor 31 läßt sich so der Hebel 27 schwenken, dadurch wird die Welle 8 gedreht, und die auf diesem befestigten Tragarme 4, 5 werden mitgeschwenkt. Anstelle des Spindelwerks 29,30 mit Getriebemotor 31 ist auch der Einsatz einer hydraulischen Kolben-Zylinder-Einheit möglich.A threaded spindle 30 is guided through the spindle nut 29 and is driven by a geared motor 31 which is rotatably fastened to the side parts 14, 15 above the roller 16. With the geared motor 31, the lever 27 can thus be pivoted, as a result of which the shaft 8 is rotated and the support arms 4, 5 fastened on it are also pivoted. Instead of the spindle mechanism 29, 30 with a gear motor 31, it is also possible to use a hydraulic piston-cylinder unit.

Der Abstand der Spannköpfe 6, 7 voneinander ist zur Aufnahme einer neuen Rolle 3 und zur Anpassung an verscheidene Rollenbreiten verstellbar. Dazu ist in jedem Tragarm 4, 5 eine Spindelmutter 32, 33 befestigt, durch die jeweils eine Gewindespindel 34, 35 Parallel zur Welle 8 nach außen führt. Die Gewindespindel 34 des Tragarms 4 ist außen in einem auf der Welle 8 befestigten Hebel 36 gelagert, an dem ein Getriebemotor 37 als Antrieb befestigt ist. Die Gewindespindel 35 des Tragarms 5 ist an der Außenseite in dem Schwenkhebel 27 gelagert und wird von einem an diesem befestigten Getriebemotor 38 angetrieben.The distance between the clamping heads 6, 7 from one another can be adjusted to accommodate a new roll 3 and to adapt to different roll widths. For this purpose, a spindle nut 32, 33 is fastened in each support arm 4, 5, through which a threaded spindle 34, 35 leads parallel to the shaft 8 to the outside. The threaded spindle 34 of the support arm 4 is mounted on the outside in a lever 36 fastened on the shaft 8, to which a geared motor 37 is fastened as a drive. The threaded spindle 35 of the support arm 5 is mounted on the outside in the pivot lever 27 and is driven by a geared motor 38 fastened thereon.

Im folgenden wird die Arbeitsweise der erfindungsgemäßen Abrollvorrichtung anhand der Figuren 3 - 6 beschrieben:The mode of operation of the rolling device according to the invention is described below with reference to FIGS. 3 to 6:

Fig. 3 zeigt die Abrollvorrichtung in Abwickelposition. Die Papierrolle 3 ist an ihrer Wickelhülse zwischen den Spannköpfen 6, 7 eingespannt und wird in angehobener Position von den Tragarmen 4, 5 freilaufend gehalten. Aus Stabilitätsgründen befindet sich die Drehachse der Rolle 3 nicht exakt vertikal oberhalb der Welle 8, sondern in einer horizontalen Position b, die etwas in Richtung des Schwenkantriebs 31 versetzt ist. In Abwickelposition befindet sich die Welle 8 in minimalem Abstand von einem sich quer zur Bahn erstreckenden Unterflurförderer 39. Die Papierbahn 40 wird oben von der Rolle 3 annähernd waagerecht in Richtung des eingezeichneten Pfeils abgezogen.Fig. 3 shows the unwinding device in the unwinding position. The paper roll 3 is clamped on its winding sleeve between the clamping heads 6, 7 and is held freely in the raised position by the support arms 4, 5. For reasons of stability, the axis of rotation of the roller 3 is not exactly vertically above the shaft 8, but in a horizontal position b, which is offset somewhat in the direction of the swivel drive 31. In the unwinding position, the shaft 8 is at a minimal distance from an underfloor conveyor 39 which extends transversely to the web. The paper web 40 is drawn off from the roll 3 approximately horizontally in the direction of the arrow shown.

Die Beschickung mit einer neuen Rolle 3 wird in den Figuren 4 - 6 gezeigt. Nachdem eine Rolle abgewickelt ist, fährt die Vorrichtung von dem Unterflurförderer 39 weg - in den Figuren 4 - 6 nach rechts - und schafft so Platz für die Zufuhr einer neuen vollen Rolle 3 durch den Förderer 39. Die Drehachse der Spannköpfe 6, 7 befindet sich nun in Position c. Die Zufuhr der neuen Rolle 3 erfolgt in axialer Richrung von der dem Hebeantrieb 29 - 31 entgegengesetzten Seite her. Die Gewindespindel 30 stört nicht, da sie an der Antriebsseite außerhalb der Arbeitsbreite angeordnet ist.(Figur 4)The loading with a new roll 3 is shown in Figures 4-6. After a roll has been unwound, the device moves away from the underfloor conveyor 39 - to the right in FIGS. 4-6 and thus creates space for the feed of a new full roll 3 by the conveyor 39. The axis of rotation of the clamping heads 6, 7 is located now in position c. The new roller 3 is fed in the axial direction from the side opposite the lifting drive 29 - 31. The threaded spindle 30 does not interfere, since it is arranged outside the working width on the drive side (FIG. 4).

Zur Aufnahme einer neuen Rolle werden die Spannköpfe 6, 7 auf einen Abstand größer als die Rollenbreite auseinander gefahren und die leere Wickelhülse wird entfernt. Dies kann während der Zufuhr der neuen Rolle 3 in die Aufnahmeposition erfolgen. Da die Vorrichtung auf der der Rollenzufuhr entgegengesetzten Seite (in Fig. 4 rechts) frei zugänglich ist, kann die leere Wickelhülse an dieser Seite entnommen werden.To take up a new roll, the clamping heads 6, 7 are moved apart a distance larger than the roll width and the empty winding tube is removed. This can be done while the new roll 3 is being fed into the take-up position. Since the device is freely accessible on the side opposite the roll feed (right in FIG. 4), the empty winding tube can be removed on this side.

Der Unterflurförderer 39 führt die Rolle ausschließlich in eine Richtung quer zur Bahn 40 in die Aufnahmeposition. Ein Transport der Rolle quer zu dieser Richtung ist nicht erforderlich.The underfloor conveyor 39 guides the roller only in one direction transverse to the web 40 into the receiving position. It is not necessary to transport the roll transversely to this direction.

Nachdem die neue Rolle 3 ihre axiale Position zwischen den Tragarme 4, 5 erreicht hat, werden die Spannköpfe 6, 7 in eine zur Rollenachse koaxiale Position gebracht (Fig. 5). Diese Positionierung erfolgt durch die Kombination einer Horizontalbewegung der Vorrichtung in Richtung auf den Unterflurförderer 39 mit einer Schwenkbewegung der Tragarme 4, 5.After the new roller 3 has reached its axial position between the support arms 4, 5, the clamping heads 6, 7 are brought into a position coaxial to the roller axis (FIG. 5). This positioning is carried out by combining a horizontal movement of the device in the direction of the underfloor conveyor 39 with a pivoting movement of the support arms 4, 5.

Durch diese kombinierte Horizontal- und Schwenkbewegung der Tragarme 4, 5 ist es möglich, mit den Spannköpfen 6, 7 jede mögliche Position der Rollenachse, die sich in Abhängigkeit vom Rollendurchmesser entlang der vertikalen Linie a verschiebt, exakt anzufahren. In Fig. 6 ist die Aufnahmeposition der Spannköpfe 6, 7 bei einem kleinen Rollendurchmesser gezeigt.Through this combined horizontal and pivoting movement of the support arms 4, 5, it is possible to precisely approach any possible position of the roller axis, which moves along the vertical line a depending on the roller diameter, with the clamping heads 6, 7. 6 shows the receiving position of the clamping heads 6, 7 with a small roller diameter.

Nachdem die Spannköpfe 6, 7 ihre Position koaxial zur Rollenachse erreicht haben, werden sie durch Zusammenfahren der Tragarme 4, 5 in die Wickelhülse eingefahren und spannen so die Rolle 3 ein. Anschließend wird die eingespannte Rolle 3 durch Hochschwenken der Tragarme 4, 5 in die vertikale Abwickelposition angehoben und durch Bewegung der Vorrichtung in horizontaler Richtung in die horizontale Abwickelposition b gebracht. Die Abrollvorrichtung mit eingespannter Rolle befindet sich dann wieder in der in Fig. 3 gezeigten Stellung.After the clamping heads 6, 7 have reached their position coaxially to the roll axis, they are moved into the winding tube by moving the support arms 4, 5 together and thus clamp the roll 3. Subsequently, the clamped roller 3 is raised into the vertical unwinding position by pivoting the support arms 4, 5 and brought into the horizontal unwinding position b by moving the device in the horizontal direction. The unwinding device with the roller clamped is then again in the position shown in FIG. 3.

In den Figuren 7 und 8 wird das Prinzip einer anderen Ausführungsform der Erfindung gezeigt, bei der die horizontale Bewegung der Schwenklager 41 nicht durch Verfahren der gesamten Abrollvorrichtung, sondern mit einer Doppellenkeraufhängung der Tragarme bewirkt wird.FIGS. 7 and 8 show the principle of another embodiment of the invention, in which the horizontal movement of the pivot bearings 41 is not effected by moving the entire rolling device, but with a double-link suspension of the support arms.

Die dort gezeigte Vorrichtung weist feststehende Stander 42 an beiden Seiten quer zur Papierbahn auf, an denen jeweils ein Hebel 43 angelenkt ist. An den nicht am Ständer 42 angelenkten Enden der Hebel 43 ist jeweils ein Tragarme 44 über eine Welle hochschwenkbar befestigt. Durch nicht dargestellte Antriebe sind die Hebel 43 an den Ständern 42 um die Anlenkachse 45 und die Tragarme 44 an den Hebel 43 im Schwenklager 41 unabhängig voneinander schwenkbar.The device shown there has fixed stands 42 on both sides transverse to the paper web, on each of which a lever 43 is articulated. At the ends of the levers 43 which are not articulated on the stand 42, a support arm 44 is fastened so as to be pivotable upward via a shaft. By means of drives, not shown, the levers 43 on the stands 42 can be pivoted independently of one another about the articulation axis 45 and the support arms 44 on the levers 43 in the pivot bearing 41.

Die Horizontalbewegung der Schwenklager 41 in Richtung des Unterflurförderers 39 zum Positionieren der Spannköpfe in die horizontalen Aufnahmestellung a wird durch Verschwenken der Hebel 43 bewirkt (Figur 8). Die vertikale Positionierung der Spannköpfe entlang der Linie a erfolgt durch die vertikalen Komponenten der beiden Schwenkbewegungen.The horizontal movement of the pivot bearings 41 in the direction of the underfloor conveyor 39 for positioning the clamping heads in the horizontal receiving position a is effected by pivoting the levers 43 (FIG. 8). The vertical positioning of the clamping heads along the line a takes place through the vertical components of the two pivoting movements.

Das Anheben der Rolle 3 und ihre Bewegung in die horizontale Abwickelposition b -Figur7- wird ebenfalls durch die Kombination der Hochschwenkbewegung der Tragarme 44 und der Schwenkbewegung der Hebel 43 durchgeführt.The lifting of the roll 3 and its movement into the horizontal unwinding position b -Figur7- is also carried out by the combination of the pivoting movement of the support arms 44 and the pivoting movement of the lever 43.

In dieser Ausführungsform bewegen sich die Schwenklager 41 der Tragarme 45 nicht exakt horizontal, sondern auf einem Kreisbogen mit einer horizontalen Komponente.In this embodiment, the pivot bearings 41 of the support arms 45 do not move exactly horizontally, but on an arc with a horizontal component.
