Definitions

  • the invention relates to a device for pivoting a reciprocating flat can on a textile machine delivering sliver during filling with sliver.
  • the flat can In the reversal points of a traversing path, the flat can is pivoted about a pivot axis by a pivoting device. The pivoting takes place transversely to the traversing path, the flat can being pivoted in a transverse direction and being pivoted in this pivoted position.

  • the German application P 43 24 951.5 shows a swiveling device in cooperation with a traversing device, the flat can being given a swiveling force in the lower can area by the swiveling device.
  • the traversing device according to P 43 24 951.5 has a transport path on which a flat can can be traversed.
  • the transport path is designed so that it can also ensure the pivoting movement of the flat can.
  • Sliding bars are arranged on both sides of the transport track. When traversing are the sliding bars with their roles on the flat can.
  • the sliding beams are controlled so that they exert a thrust across the traversing path in the reversal points of the traversing path.
  • the flat can is moved laterally to the next reversal point and then laterally again in the opposite direction. This pushing device is complex due to the sliding bar and expensive.
  • the object of the invention is to arrange a device for pivoting a flat can, which requires considerably less effort and is less expensive.
  • a swivel device is arranged in relation to the flat can at the level of the upper can area.
  • the can area is an area that lies between the upper edge of the can and a gripper plate that grips the flat can by means of a gripper device.

If the flat can reaches a reversal point of its traversing path, then both swivel encoders pivot the flat can transversely to the traversing path. The Flat can is thus pivoted about its pivot axis at a fixed angle. In this position the flat jug oscillates back to the other turning point. When the other reversal point is reached, the swivel encoders swivel the flat can over the traversing path in the opposite transverse direction. This process is repeated until the jug is full and a jug change is indicated.
  • the swivel encoders are preferably designed as rollers which have an eccentric axis.

Description

Die Erfindung betrifft eine Vorrichtung zum Hin- und Zurückschwenken einer changierenden Flachkanne an einer Faserband abliefernden Textilmaschine während des Befüllens mit Faserband. In den Umkehrpunkten eines Changierweges wird die Flachkanne durch eine Schwenkvorrichtung jeweils um eine Schwenkachse geschwenkt. Das Schwenken erfolgt quer zum Changierweg, wobei die Flachkanne in einer Querrichtung hin geschwenkt wird und in dieser geschwenkten Stellung changiert wird. Im Umkehrpunkt des Changierweges wird die Flachkanne in Überquerung des Changierweges in die entgegengesetzte Querrichtung zurückgeschwenkt und nun in dieser Lage changiert.The invention relates to a device for pivoting a reciprocating flat can on a textile machine delivering sliver during filling with sliver. In the reversal points of a traversing path, the flat can is pivoted about a pivot axis by a pivoting device. The pivoting takes place transversely to the traversing path, the flat can being pivoted in a transverse direction and being pivoted in this pivoted position. At the reversal point of the traversing path, the flat can is swung back in the opposite transverse direction while crossing the traversing path and is now oscillated in this position.

Die deutsche Anmeldung P 43 24 951.5 zeigt eine Schwenkvorrichtung im Zusammenwirken mit einer Changiervorrichtung, wobei die Flachkanne durch die Schwenkvorrichtung eine Schwenkkraft im unteren Kannenbereich erhält. Die Changiervorrichtung nach P 43 24 951.5 hat eine Transportbahn auf der eine Flachkanne changierbar ist. Die Transportbahn ist so gestaltet, daß sie auch die Schwenkbewegung der Flachkanne gewährleisten kann. Zur Transportbahn sind beidseitig Schiebebalken angeordnet. Beim Changieren liegen die Schiebebalken mit ihren Rollen an der Flachkanne an. Die Schiebebalken werden so gesteuert, daß sie in den Umkehrpunkten des Changierweges einen Schub quer zum Changierweg ausüben. Die Flachkanne wird quer verschoben bis zum nächsten Umkehrpunkt und dann in entgegengesetzter Richtung erneut quer verschoben. Diese Schubvorrichtung ist infolge der Schiebebalken aufwendig im Aufbau und kostenintensiv.The German application P 43 24 951.5 shows a swiveling device in cooperation with a traversing device, the flat can being given a swiveling force in the lower can area by the swiveling device. The traversing device according to P 43 24 951.5 has a transport path on which a flat can can be traversed. The transport path is designed so that it can also ensure the pivoting movement of the flat can. Sliding bars are arranged on both sides of the transport track. When traversing are the sliding bars with their roles on the flat can. The sliding beams are controlled so that they exert a thrust across the traversing path in the reversal points of the traversing path. The flat can is moved laterally to the next reversal point and then laterally again in the opposite direction. This pushing device is complex due to the sliding bar and expensive.

Aufgabe der Erfindung ist es in Verbindung mit einer Changiervorrichtung für eine Flachkanne an einer Faserband abliefernden Textilmaschine, eine Vorrichtung zum Schwenken einer Flachkanne anzuordnen, die wesentlich weniger Aufwand erfordert und kostengünstiger ist.In connection with a traversing device for a flat can on a textile machine delivering a sliver, the object of the invention is to arrange a device for pivoting a flat can, which requires considerably less effort and is less expensive.

Die Aufgabe wird dadurch gelöst, daß eine Schwenkvorrichtung im Bezug auf die Flachkanne in Höhe des oberen Kannenbereiches angeordnet ist. Dabei ist der Kannenbereich ein Bereich der zwischen dem oberen Kannenrand und einer die Flachkanne mittels Greifervorrichtung greifenden Greiferplatten liegt. In diesem Bereich wirkt die Schwenkvorrichtung und dort ist sie vorzugsweise angeordnet. Die Schwenkvorrichtung hat als Arbeitsmittel zwei Schwenkgeber. Die Schwenkgeber sind jeweils in Nähe des oberen Kannenbereiches beidseitig der Flachkanne angeordnet. Sie sind in einer vorteilhaften Ausführung am unteren Maschinentisch einander gegenüberliegend bezüglich eines Drehtellers angeordnet. Die Schwenkgeber geben der Flachkanne im oberen Kannenbereich nicht nur die Schwenkbewegung, sondern gleichzeitig eine Führung während des Changierens. Erreicht die Flachkanne einen Umkehrpunkt ihres Changierweges, dann schwenken beide Schwenkgeber die Flachkanne um einen festgelegten Betrag quer zum Changierweg. Die Flachkanne wird somit um ihre Schwenkachse in einem festgelegten Winkel geschwenkt. In dieser Stellung changiert die Flachkanne zurück zu dem anderen Umkehrpunkt. Mit Erreichen des anderen Umkehrpunktes schwenken die Schwenkgeber die Flachkanne über den Changierweg hinweg in die entgegengesetzte Querrichtung. Dieser Vorgang wiederholt sich bis die Kanne gefüllt ist und ein Kannenwechsel angezeigt ist.The object is achieved in that a swivel device is arranged in relation to the flat can at the level of the upper can area. The can area is an area that lies between the upper edge of the can and a gripper plate that grips the flat can by means of a gripper device. The pivoting device acts in this area and is preferably arranged there. The swivel device has two swivel encoders as work equipment. The swivel sensors are arranged in the vicinity of the upper can area on both sides of the flat can. In an advantageous embodiment, they are arranged on the lower machine table opposite one another with respect to a turntable. The swivel encoders not only give the flat can in the upper can area the swiveling movement, but at the same time guide it during traversing. If the flat can reaches a reversal point of its traversing path, then both swivel encoders pivot the flat can transversely to the traversing path. The Flat can is thus pivoted about its pivot axis at a fixed angle. In this position the flat jug oscillates back to the other turning point. When the other reversal point is reached, the swivel encoders swivel the flat can over the traversing path in the opposite transverse direction. This process is repeated until the jug is full and a jug change is indicated.

Die Schwenkgeber sind vorzugsweise als Rollen ausgebildet, die eine exzentrische Achse besitzen. Die Rollen sind mit ihrer Achse in einer vorteilhaften Ausführungsform an der Unterseite des Maschinentisches einander gegenüberliegend bezüglich eines Drehtellers angeordnet. Durch zeitgleiches Verdrehen beider Rollen mit ihrer exzentrischen Achse entsprechend einem festgelegten Winkel wird ein Schwenken der Flachkanne um ihre Schwenkachse erzielt. Die Drehbewegung einer Rolle wird durch einen steuerbaren Zylinder erreicht, der im Eingriff mit einem Verstellhebel für die Rolle ist. Die Steuerung ermöglicht einen Hub oder Zug der Kolbenstange eines Zylinders, so daß die Rolle um einen notwendigen Winkel mit ihrer exentrischen Achse gedreht werden kann. Die Mantelfläche einer Rolle ist gegenüber dem Grundkörper der Rolle drehbar. Da die Rolle an der Kannenwandung anliegt, wird durch Verdrehen der Rolle die Flachkanne quer zum Changierweg geschwenkt. Die Ausbildung der Schwenkgeber als Rollen ist besonders vorteilhaft, weil ein äußerst geringer baulicher Aufwand zum Erzeugen einer Schwenkbewegung besteht und durch die Rollen zugleich eine vorteilhafte Führung der Flachkanne während des Changierens gewährleistet wird. Diese Art der Führung ist in vorteilhafter Weise reibungsarm. Als ein weiterer Vorteil zeigt sich, daß beispielsweise bei einer Changierung der Flachkanne auf einer Transportbahn, die am Boden befindliche Transportbahn freigemacht ist von einer Schwenkvorrichtung und somit eine bessere Zugänglichkeit für ein Transportsystem beim Kannenwechsel existiert.The swivel encoders are preferably designed as rollers which have an eccentric axis. In an advantageous embodiment, the rollers are arranged opposite one another with respect to a turntable on the underside of the machine table. By simultaneously rotating both rollers with their eccentric axis according to a defined angle, the flat can is pivoted about its pivot axis. The rotational movement of a roller is achieved by a controllable cylinder which is in engagement with an adjusting lever for the roller. The control enables a stroke or pull of the piston rod of a cylinder, so that the roller can be rotated through a necessary angle with its eccentric axis. The outer surface of a roller is rotatable relative to the base body of the roller. Since the roller lies against the can wall, the flat can is pivoted transversely to the traversing path by rotating the roller. The design of the swivel transmitter as rollers is particularly advantageous because there is an extremely low structural outlay for generating a swivel movement and, at the same time, the rollers ensure an advantageous guidance of the flat can during traversing. This type of guidance is advantageously low-friction. Another advantage is that, for example, when the flat can is moved on a Transport path, the transport path located on the ground is clear of a swivel device and thus there is better accessibility for a transport system when changing the can.

Figur 1 zeigt die Ablagevorrichtung 1 einer Strecke der Textilindustrie. Es ist aber auch eine Ablagevorrichtung einer Karde zutreffend, wobei nachfolgend Wesentliches anhand der Strecke beschrieben wird. Beides sind Faserband abliefernde Textilmaschinen. Im Maschinentisch 4 ist drehbar ein Drehteller 2 mit Bandführungskanal 3 angeordnet. Oberhalb des Bandführungskanals 3 befindet sich ein Kalanderwalzenpaar 10, 10'. Das Kalanderwalzenpaar 10, 10' fördert beim Befüllen einer Flachkanne Faserband FB in den Bandführungskanal 3 eines Drehtellers 2, der dieses Faserband zykloidenförmig in einer Flachkanne 5 ablegt. Während der Ablage des Faserbandes FB wird die Flachkanne 5 auf dem Changierweg A B changiert. Dabei wird die Kanne von einer Greifvorrichtung erfaßt. Die Kanne ist deshalb zwischen den Greiferplatten 6, 8 angeordnet, die Teil einer Greifvorrichtung sind. Die Greiferplatte 6 ist mit der Achse 17 drehbar in einem Greiferarm 7 gelagert. Die Greiferplatte 8 ist mit der Achse 17' drehbar in dem Greiferarm 9 gelagert. Greiferarme 7, 9 mit Greiferplatten 6, 8 changieren die Flachkanne 5 entlang einer Schiene 12 mit Anschlag. Der Anschlag der Schiene 12 entspricht jeweils den Umkehrpunkten A bzw. B des Changierweges A B. Die Flachkanne 5 kann frei hängend changiert werden oder sie kann auf einer Transportbahn stehend changiert werden.Figure 1 shows the storage device 1 of a stretch of the textile industry. However, a carding device is also applicable, the essentials of which are described below with reference to the route. Both are textile machines that deliver sliver. In the machine table 4, a turntable 2 with a band guide channel is rotatable 3 arranged. A pair of calender rolls 10, 10 'is located above the belt guide channel 3. The pair of calender rolls 10, 10 ', when filling a flat can, feeds sliver FB into the sliver guide channel 3 of a turntable 2, which deposits this sliver in a cycloidal shape in a flat can 5. While the sliver FB is being deposited, the flat can 5 is oscillated on the traversing path AB. The jug is gripped by a gripping device. The jug is therefore arranged between the gripper plates 6, 8, which are part of a gripping device. The gripper plate 6 is rotatably mounted with the axis 17 in a gripper arm 7. The gripper plate 8 is rotatably mounted in the gripper arm 9 with the axis 17 '. Gripper arms 7, 9 with gripper plates 6, 8 oscillate the flat can 5 along a rail 12 with a stop. The stop of the rail 12 corresponds in each case to the reversal points A or B of the traversing path A B. The flat can 5 can be traversed freely hanging or it can be traversed standing on a transport path.

Figur 2 zeigt eine Seitenansicht zu Figur 1, wobei sichtbar wird, daß die Changiervorrichtung 11 einen Changierwagen 16 hat, der auf der Schiene 12 verfahrbar angeordnet ist. Der Changierwagen 16 besitzt Greiferarme. Dargestellt ist in der Seitenansicht ein Greiferarm 9 mit Greiferplatte 8. Im oberen Kannenbereich ist eine Schwenkvorrichtung 15 angeordnet. Die Schwenkvorrichtung 15 besitzt als Arbeitsmittel Schwenkgeber 13, 14. Die Schwenkgeber sind beidseitig im oberen Kannenbereich angeordnet. Um die Anzahl notwendiger Schwenkgeber gering zu halten, werden bezüglich einer Anordnung von 2 Schwenkgebern im oberen Kannenbereich, diese bezüglich ihrer Anordnung an der Unterseite des Maschinentisches vorteilhafterweise in Nähe des Drehtellers angeordnet. Den oberen Kannenbereich erläutert Figur 3. Der obere Kannenbereich 19 ist begrenzt durch den oberen Kannenrand 18 und die die Flachkanne haltenden Greiferplatten 6, 8. In diesem oberen Kannenbereich 19 wird wahlweise die Schwenkvorrichtung 15 mit den Schwenkgebern 13, 14 angeordnet werden. Generell ist auch eine Anordnung der Schwenkvorrichtung in einem unteren Kannenbereich möglich. Ein unterer Kannenbereich wäre analog dem oberen zu definieren. Das ist jedoch weniger vorteilhaft.FIG. 2 shows a side view of FIG. 1, it becoming apparent that the traversing device 11 has a traversing carriage 16 which is arranged to be movable on the rail 12.

A lower can area should be defined in the same way as the upper one. However, this is less advantageous.

Eine Anordnung im oberen Kannenbereich 19 ist vorteilhafter, weil eine Behinderung mit einem im unteren Kannenbereich operierenden Transportsystem für die Kanne vermieden wird. Dieses Transportsystem ist aus Gründen der Übersichtlichkeit nicht dargestellt.An arrangement in the upper can region 19 is more advantageous because obstruction with a transport system for the can operating in the lower can region is avoided. This transport system is not shown for reasons of clarity.

Die Schwenkgeber 13, 14 können vorteilhaferweise an der Unterseite des Maschinentisches 4 angeordnet sein. Die Schwenkgeber werden durch eine Steuervorrichtung 100 geführt. Die Steuervorrichtung 100 veranlaßt durch ihr Programm, daß im Umkehrpunkt des Changierweges beide Schwenkgeber zeitgleich in eine gemeinsame Richtung quer zum Changierweg schwenken. So wird die Flachkanne geschwenkt. Das Erreichen eines Umkehrpunktes A oder B wird der Steuervorrichtung 100 durch Sensoren 101, 102 gemeldet, die jeweils im Umkehrpunkt A bzw. B. angeordnet sind. Erreicht die Kanne ihren anderen Umkehrpunkt, schwenken die Schwenkgeber die Flachkanne um die Schwenkachse 17, 17' in die entgegengesetzte Richtung quer zum Changierweg. Zu diesem Zweck ist jeder einzelne Schwenkgeber mit einem steuerbaren Antrieb ausgerüstet. Die Arbeitsweise dieser Schwenkgeber ist schematisch in Figur 4 bis 4b dargestellt. Die Darstellungen zeigen eine Draufsicht auf die Flachkanne 5, von der Unterseite des Maschinentisches 4 aus betrachtet. Schematisch ist in Figur 4 der Drehteller in Strichlinie dargestellt, der im Maschinentisch 4 angeordnet ist. Figur 4 zeigt eine Grundstellung der Flachkanne 5. So ist beispielsweise eine vom Transportsystem zugeführte Leerkanne positioniert bevor der Füllvorgang beginnt. Analog betrifft es auch die gefüllte Kanne, die an ein Transportsystem zu übergeben ist. Die Schwenkachse 22 liegt symmetrisch zu den Seitenwandungen der Flachkanne 5. Die Schwenkvorrichtung 15 ist im oberen Kannenbereich 19 angeordnet. Die Draufsicht zeigt, daß beidseitig der Kannenwandung Schwenkgeber 13, 14 angeordnet sind. Die Schwenkgeber sind in vorteilhafter Ausführung Rollen, die jeweils mit einer exzentrisch gelagerten Achse 20, 21 verbunden sind. Es können auch andere, äquivalente Mittel zur Rolle genutzt werden. Diese Drehachsen 20, 21 können beispielsweise an der Unterseite des Maschinentisches 4 befestigt sein und ragen somit senkrecht in die Bildebene von Figur 4 hinein. Wie weiterhin erkennbar ist, ist der Drehteller 2 im Maschinentisch 4 zwischen den Schwenkgebern 13, 14 angeordnet, aber in einer Ebene mit dem Maschinentisch. Aus Gründen der Übersichtlichkeit ist der Drehteller 2 in Figur 4a, 4b nicht dargestellt.The pivot sensors 13, 14 can advantageously be arranged on the underside of the machine table 4. The swivel encoders are guided by a control device 100. The control device 100 causes through its program that at the reversal point of the traversing path both swivel encoders simultaneously pivot in a common direction transverse to the traversing path. This is how the flat jug is swiveled. Reaching a reversal point A or B is reported to the control device 100 by sensors 101, 102, which are each arranged at the reversal point A or B. When the can reaches its other point of reversal, the swivel sensors pivot the flat can about the pivot axis 17, 17 'in the opposite direction transverse to the traversing path. For this purpose, each individual swivel encoder is equipped with a controllable drive. The operation of this swivel encoder is shown schematically in Figures 4 to 4b. The illustrations show a top view of the flat can 5, viewed from the underside of the machine table 4. The turntable, which is arranged in the machine table 4, is shown schematically in FIG. FIG. 4 shows a basic position of the flat can 5. For example, an empty can supplied by the transport system is positioned before the filling process begins. The same applies to the filled jug, which is to be transferred to a transport system. The pivot axis 22 is symmetrical to the side walls of the flat can 5. The pivot device 15 is arranged in the upper can region 19. The top view shows that swivel sensors 13, 14 are arranged on both sides of the can wall. In an advantageous embodiment, the swivel encoders are rollers which are each connected to an eccentrically mounted axis 20, 21. Other equivalent means of role can also be used. These axes of rotation 20, 21 can, for example, be fastened to the underside of the machine table 4 and thus project perpendicularly into the image plane of FIG. 4. As can also be seen, the turntable 2 is arranged in the machine table 4 between the swivel encoders 13, 14, but in one plane with the machine table. For reasons of clarity, the turntable 2 is not shown in FIGS. 4a, 4b.

Figur 4a zeigt ein Schwenken der Flachkanne 5 nachdem die Flachkanne einen Umkehrpunkt (nicht dargestellt) erreicht hat. Die einem Umkehrpunkt abgewandte Stirnseite mit teilweiser Seitenwandung ist dargestellt. Im vorliegenden Beispiel wird die Flachkanne 5 durch Drehung der als Rollen ausgebildeten Schwenkgeber 13, 14 um die Achsen 20, 21 nach rechts R geschwenkt.Figure 4a shows a pivoting of the flat can 5 after the flat can has reached a turning point (not shown). The end face facing away from a turning point with partial side wall is shown. In the present example, the flat can 5 is pivoted to the right R about the axes 20, 21 by rotating the swivel sensors 13, 14 designed as rollers.

Figur 4b zeigt den Vorgang beim Erreichen des anderen Umkehrpunktes. Die Schwenkgeber 13, 14, die als Rollen ausgebildet sind, drehen in die andere Richtung im Vergleich zu Fig. 4a. Dadurch wird die Flachkanne 5 um die Schwenkachse 22 nach links L geschwenkt. Die Schwenkachse 22 aus den Figuren 4 bis 4b entspricht der Schwenkachse 17, 17' nach den Figuren 1 und 2.Figure 4b shows the process when the other reversal point is reached. The swivel encoders 13, 14, which are designed as rollers, rotate in the other direction compared to Fig. 4a. As a result, the flat can 5 is pivoted about the pivot axis 22 to the left L. The pivot axis 22 from FIGS. 4 to 4b corresponds to the pivot axis 17, 17 'according to FIGS. 1 and 2.

Figur 5 zeigt eine mögliche Ausführungsform eines Schwenkgebers. Ein Schwenkgeber 13, 14 kann beispielsweise als Rolle 23 ausgebildet sein. Die Rolle 23 besitzt eine exzentrisch angeordnete Achse 27. In dieser Achse ist ein Verstellhebel 24 drehbar angeordnet. Der Verstellhebel 24 befindet sich mittels der Achse 25 im Eingriff mit einer Verstellvorrichtung, die beispielsweise ein Pneumatikzylinder 26 sein kann. Die Rolle 23 ist so gestaltet, daß bei Schub oder Zug der Kolbenstange 30 des Zylinders 26 der Verstellhebel 24 die Rolle 23 zwischen ihrer dargestellten Position und der Position Rolle 23' verstellen kann. Schub oder Zug der Kolbenstange 30 wird durch die Steuervorrichtung 100 veranlaßt, die über Verbindungsleitungen 103, 104 verbunden ist. Die Mantelfläche der Rolle 23 ist gegenüber dem Grundkörper der Rolle drehbar. Der Grundkörper ist mit der Achse verbunden.Figure 5 shows a possible embodiment of a swivel encoder. A pivot encoder 13, 14 can be designed, for example, as a roller 23. The roller 23 has an eccentrically arranged axis 27. An adjusting lever 24 is rotatably arranged in this axis. The adjusting lever 24 is engaged by means of the axis 25 with an adjusting device, which can be a pneumatic cylinder 26, for example. The roller 23 is designed so that when the piston rod 30 of the cylinder 26 is pushed or pulled, the adjusting lever 24 can adjust the roller 23 between its position shown and the roller 23 'position. Thrust or pull of the piston rod 30 is caused by the control device 100, which is connected via connecting lines 103, 104. The outer surface of the roller 23 is rotatable relative to the base body of the roller. The base body is connected to the axis.

Je ein Zylinder 26 wird von der Steuervorrichtung 100 betätigt, die ihr Signal wiederum von einem der Sensoren 101, 102 erhält, die die Ankunft der Kanne im Umkehrpunkt A bzw. B melden.Each cylinder 26 is actuated by the control device 100, which in turn receives its signal from one of the sensors 101, 102, which report the arrival of the can at the reversal point A or B.

Figur 6 zeigt schematisch den Aufbau einer einzelnen Rolle 23. Der Blick ist auf die Rolle 23 gerichtet in Richtung Unterseite des Maschinentisches 4.FIG. 6 schematically shows the structure of an individual roller 23. The view is directed towards the roller 23 towards the underside of the machine table 4.

Die Rolle 23 hat eine Mantelfläche 230, die von einem Ring 232 gebildet wird. Der Ring 232 ist mittels Kugellager 108 gegenüber dem Grundkörper 231 drehbar. Der Grundkörper 232 wird gebildet durch Nabe 233 mit Langloch 106 und entsprechender Abdeckplatte 105, die ebenfalls das Langloch 106 nicht verdeckt. Die Abdeckplatte 105 ist mittels Verschraubung 107 an der Nabe 233 befestigt. Dieser beschriebene Grundkörper 231 ist in der Achse 27 gangeordnet. Der Grundkörper 231 ist mittels Verschraubung 234 im Langloch 106 entsprechend der Meßskala 109 verschiebbar und fixierbar. Somit ist der Grad der Exzentrizität der Rolle 23 gegenüber der Achse 27 einstellbar.The roller 23 has an outer surface 230, which is formed by a ring 232. The ring 232 is opposed by means of ball bearings 108 the base body 231 rotatable. The base body 232 is formed by a hub 233 with an elongated hole 106 and a corresponding cover plate 105, which likewise does not cover the elongated hole 106. The cover plate 105 is fastened to the hub 233 by means of screw connection 107. This basic body 231 described is arranged in the axis 27. The base body 231 can be displaced and fixed in the elongated hole 106 by means of screw connection 234 in accordance with the measuring scale 109. The degree of eccentricity of the roller 23 with respect to the axis 27 can thus be adjusted.

Figur 7 zeigt insbesondere die Rolle 23 nach Schnitt A-B aus der Figur 6. Dabei wird erkennbar die Einstellbarkeit der Exzentrizität der Rolle 23 durch Verschiebung der Rolle im Langloch 106. Es ist weiterhin erkennbar die Drehbarkeit der Mantelfläche 230 des Ringes 232 gegenüber dem feststehenden Grundkörper 231. Die vom Verstellhebel 24 ausgehende Drehung wird auf die Achse 27 übertragen und letztlich auf die Rolle 23 übertragen. Somit wird ein Schwenken der Rolle 23 um einen gewünschten Winkel möglich.FIG. 7 shows, in particular, the roller 23 according to section AB from FIG. 6. The adjustability of the eccentricity of the roller 23 by shifting the roller in the elongated hole 106 can be seen. The rotatability of the outer surface 230 of the ring 232 relative to the fixed base body 231 can also be seen The rotation emanating from the adjusting lever 24 is transmitted to the axle 27 and ultimately to the roller 23. This enables the roller 23 to be pivoted through a desired angle.
