Abstract

Ein zur Aufnahme des Wickels (20) dienender, ringförmi­ger Wickelkern (l9) ist mit seiner zylinderischen Innen­seite (l9a) reibschlüssig auf antreibbare Tragräder (28, 29) auflegbar und von diesen abhebbar. Auf die Innensei­te (l9a) des aufgelegten Wickelkernes (l9) ist unterhalb der Tragräder (28, 29) ein im wesentlichen frei drehba­res Führungsrad (30) zur Einwirkung bringbar, welches ein Abheben des Wickelkernes (l9) von den Tragrädern (28, 29) verhindert und den dazwischen vorhandenen Reib­schluss erhöhen kann. Um Wickelkerne (l9) mit einer rein zylindrischen,glatten Innenfläche benützen zu können und dennoch bei der Drehung deren exakte Positionierung in Achsrichtung zu gewährleisten, ist das Führungsrad (30) in seiner Wirklage um eine bezüglich des aufgelegten Wickelkernes (l9) radial gerichtete Lenkachse (59) aus­lenkbar, was dem drehenden Wickelkern (l9) eine axiale Bewegungskomponente vermittelt, wobei eine Anschlagan­ordnung (62) zur Begrenzung dieser Axialbewegung vorge­sehen ist.

A ring-shaped winding core (l9) serving to receive the winding (20) can be placed with its cylindrical inside (l9a) frictionally on drivable carrying wheels (28, 29) and lifted off from these. An essentially freely rotatable guide wheel (30) can be brought into effect on the inside (l9a) of the wound winding core (l9) below the carrying wheels (28, 29), said guide wheel (30) lifting the winding core (l9) off the carrying wheels (28, 29). prevented and can increase the existing friction between. In order to be able to use winding cores (l9) with a purely cylindrical, smooth inner surface and still ensure their exact positioning in the axial direction during rotation, the guide wheel (30) is in its operative position around a steering axis which is radially oriented with respect to the winding core (l9) placed on it. 59) can be deflected, which imparts an axial movement component to the rotating winding core (l9), a stop arrangement (62) being provided to limit this axial movement.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Auf- oder Abwickeln von kontinuierlich, insbesondere ge­schuppt anfallenden, biegsamen Flächengebilden, vorzugs­weise Druckprodukten zu bezw. ab einem Wickel gemäss dem Oberbegriff des Patentanspruches l.The present invention relates to a device for winding or unwinding continuous, in particular flaking, flexible sheet-like structures, preferably printed products. from a roll according to the preamble of claim l.

Eine solche Vorrichtung ist aus der am 2l. November l985 unter der Nr. 0 l6l 569 veröffentlichten europäischen Patentanmeldung bekannt.Such a device is from the 2l. European patent application published on November 1885 under No. 0 1661 569.

Bei dieser vorbekannten Vorrichtung ist der ringförmige Wickelkern, im Falle, dass er angetrieben wird, der an­getriebene Teil eines Reibradgetriebes und die als Lage­rung dienenden Tragräder, auf denen der Wickelkern mit seiner Innenseite aufliegt, sind zugleich das an­treibende Teil des Reibradgetriebes.In this known device, the ring-shaped winding core, in the case that it is driven, is the driven part of a friction gear and the supporting wheels serving as bearings, on which the inside of the winding core rests, are at the same time the driving part of the friction gear.

Damit der Wickelkern während seiner Drehung nicht in axialer Richtung abwandert, oder auch nur seine axiale Lage verändern kann, (was zu einem konischen Wickel füh­ren würde) weist der Wickelkern der bekannten Vorrich­tung nach innen ragende Seitenflansche auf, die gewis­sermassen als Spurkranz mit den Stirnflächen der Trag­räder, aber auch des Führungsrades zusammenwirken.So that the winding core does not migrate in the axial direction during its rotation, or can even only change its axial position (which would lead to a conical winding), the winding core of the known device has inwardly projecting side flanges, which are to a certain extent a flange with the end faces of the Support wheels, but also the guide wheel interact.

Dies zieht verschiedene Nachteile mit sich: Der Wickel­ kern und insbesondere der Abstand dessen Seitenflansche voneinander sind der Dicke der Tragräder und des Füh­rungsrades anzupassen, die ihrerseits nicht als Walzen ausgebildet werden können. Die Dicke der Tragräder und jene des Führungsrades müssen sich entsprechen und darü­ber hinaus müssen die Stirnflächen aller Räder je in einer Ebene liegen, sollen sie Seitenflansche des Wickelkernes ihrer Rolle als Spurkränze gerecht werden. Darüber hinaus muss bei der vorbekannten Einrichtung zum Abheben des Wickelkernes von den Tragrädern dieser zunächst zumindest um das radiale Mass der Seitenflan­sche lotrecht angehoben werden, bevor der Wickelkern in axialer Richtung entfernt werden kann. Dieses lotrechte Anheben bedarf insbesondere bei voll bewickeltem Wickel­kern eines erheblichen Kraftaufwandes. Letztlich ist bei der bekannten Einrichtung bei der Bemessung des Wickel­kernes stets ein Kompromiss zu schliessen. Einerseits muss dieser bezüglich seiner Seitenflansche - wie er­wähnt - der Dicke der Räder angepasst sein, und anderer­seits sollte dessen äussere Aussenfläche einigermassen dem Format der aufzuwickelnden Flächengebilde angepasst sein, damit diese möglichst auf dem grössten Teil ihrer Breite direkt oder indirekt auf der äusseren Mantelflä­che des Wickelkernes abgestütz sind.This has several disadvantages: the wrap core and in particular the distance between its side flanges from each other are to be adapted to the thickness of the support wheels and the guide wheel, which in turn cannot be designed as rollers. The thickness of the supporting wheels and that of the guide wheel must correspond and, moreover, the end faces of all wheels must each lie in one plane if they are to meet the side flanges of the winding core in their role as wheel flanges. In addition, in the known device for lifting the winding core from the carrying wheels, the winding core must first be lifted perpendicularly at least by the radial dimension of the side flanges before the winding core can be removed in the axial direction. This vertical lifting requires considerable effort, in particular when the winding core is fully wound. Ultimately, a compromise must always be made in the known device when dimensioning the winding core. On the one hand, the side flanges - as mentioned - have to be adapted to the thickness of the wheels, and on the other hand, the outer surface of the wheels should be adapted to the format of the flat material to be wound up so that it is as direct or indirect as possible over the largest part of its width on the outer surface of the winding core are supported.

Bei diesem Stand der Technik ist es als ein Zweck der Erfindung anzusehen, eine Vorrichtung der eingangs ge­nannten Gattung zu schaffen, bei der der Wickelkern rein hohlzylindrisch, also etwa die Form eines flanschlosen Rohrabschnittes aufweisen kann, was die Entfernung des Wickelkernes erleichtert und dessen bessere Anpassung an die Breite der Flächengebilde ermöglicht. Ausserdem sol­len weder die Tragräder noch das Führungsrad - abgesehen von ihrem Zusammenwirken mit der Innenseite des Wickel­kernes - unabhängig von der Ausbildung des Wickelkernes bemessen werden können, wobei die gleichbleibende axiale Lage des Wickelkernes bei seiner Drehung dennoch gewähr­leistet bleibt.In this prior art, it is to be regarded as a purpose of the invention to provide a device of the type mentioned in the introduction, in which the winding core can be purely hollow-cylindrical, that is to say approximately in the form of a flangeless pipe section, which means that the removal of the Winding core facilitated and its better adaptation to the width of the fabric enables. In addition, neither the idler wheels nor the guide wheel - apart from their interaction with the inside of the winding core - should be able to be dimensioned independently of the design of the winding core, the constant axial position of the winding core still being guaranteed during its rotation.

Zu diesem Zweck weist die vorgeschlagene Einrichtung die im Kennzeichen des Patentanspruches l angegebenen Merk­male auf.For this purpose, the proposed device has the features specified in the characterizing part of patent claim 1.

Wenn nun dem Führungsrad ein Lenkausschlag gegeben wird, das heisst, wenn seine Drehachse nicht mehr genau paral­lel zu den Drehachsen der Tragräder ist, erfährt der Wickelkern bei seiner Drehung zusätzlich eine axiale Be­wegungskomponente, die je nach Drehrichtung des Wickel­kernes und nach der Seite des Lenkausschlages den Wickelkern entweder zur Anschlaganordrung drängt, womit seine axiale Lage festgelegt ist, oder aber die den Wickelkern von der Anschlaganordnung entfernt, was die Entfernung des Wickelkernes bedeutend vereinfacht. Für den Lenkausschlag des Führungsrades sind einige wenige Winkelgrade ausreichend.If the steering wheel is now given a steering deflection, i.e. if its axis of rotation is no longer exactly parallel to the axes of rotation of the idler wheels, the winding core also experiences an axial movement component during its rotation, which, depending on the direction of rotation of the winding core and on the side of the steering deflection The winding core either urges the stop arrangement, which fixes its axial position, or it removes the winding core from the stop arrangement, which considerably simplifies the removal of the winding core. A few degrees of angle are sufficient for the steering deflection of the guide wheel.

  • Fig. 5 shows an embodiment variant in a similar representation as Fig. 2, but on an even larger scale.

Es sei nun - auch im Sinne einer Erläuterung des Oberbe­griffes des Patentanspruches l - zunächst auf Fig. l Be­zug genommen.It is now - also in the sense of an explanation of the preamble of claim 1 - first referred to Fig. 1.

Bei der in Fig. l dargestellten Vorrichtung l0 treibt ein Motor ll über eine Kette l2, ein Vorgelege l3, über ein Getriebe l4 sowie über eine weitere Kette l5 eine Umlenkrolle l6 eines Bändchenförderers l7 an. Der Bänd­chenförderer l7 ist von einem nicht dargestellten, wip­penartigen Rahmen getragen, der um die Drehachse der Um­lenkrolle l6 schwenkbar ist und mittels einer Gasfeder l8 stets an den Aussenumfang eines Wickelkernes l9, bezw. eines darauf in Bildung begriffenen Wickels 20 drängt. Der Bändchenförderer l7 führt dem Wickel die nicht dargestellten, biegsamen Flächengebilde zu, bezw. fördert solche Flächengebilde beim Abwickeln des Wickels ab. Ueber eine weitere, vom Getriebe l4 ausgehende Kette 2l ist eine Vorratsrolle 22 für ein Wickelband 23 ange­trieben, das seinerseits den Bändchenförderer l7 im Be­reich dessen Berührungsstelle am Wickelkern l9, bezw. am Wickel 20 durchsetzt und im Zuge des Aufwickelns der vom Bändchenförderer angelieferten Flächengebilde (nicht dargestellt) mit aufgewickelt wird, bezw. beim Abwickeln des Wickels 20 wieder auf die Vorratsrolle 22 aufgespult wird.In the device l0 shown in FIG. 1, a motor 11 drives a deflection roller l6 of a ribbon conveyor l7 via a chain l2, a countershaft l3, via a transmission l4 and via a further chain l5. The ribbon conveyor l7 is carried by a rocker-type frame, not shown, which can be pivoted about the axis of rotation of the deflection roller l6 and by means of a gas spring l8 always on the outer circumference of a winding core l9, resp. of a winding 20 being formed thereon urges. The ribbon conveyor l7 leads to the winding, not shown, flexible fabrics, respectively. promotes such fabrics when unwinding the roll. A supply roll 22 for a winding belt 23 is driven via a further chain 2l starting from the transmission l4, which, in turn, feeds the ribbon conveyor l7 in the area of its contact point on the winding core l9. interspersed on the winding 20 and in the course of the winding up of the fabric (not shown) supplied by the ribbon conveyor is also wound up, respectively. is wound back onto the supply roll 22 when the roll 20 is unwound.

Vom Vorgelege l3 führt eine weitere Kette 24 zu einem Wickelgetriebe 25 mit selbsttätig stufenlos verändebaren Uebersetzungsverhältnis. Vom Wickelgetriebe 25 führt eine weitere Kette 26 zu zwei über nochmals eine Kette 27 zu gleichsinniger Drehung miteinander verbundenen Tragrädern 28, 29, auf denen der Wickelkern l9 gelagert ist und die - falls angetrieben - den Wickelkern l9 reibschlüssig in demselben Drehsinn antreiben. Ergänzt wird die Lagerung des Wickelkernes l9 durch ein im we­sentlichen frei drehbares Führungsrad 30, das heb- und senkbar ist und in abgesenkter Stellung ebenfalls mit der Innenseite des Wickelkernes l9 zusammenwirkt und dann nicht nur ein ungewolltes Abheben des Wickelkernes l9 von einem der Tragräder 28, 29 verhindert, sondern auch zur Erhöhung des Reibschlusses zwischen diesen und der Innenseite l9a des Wickelkernes l9 beitragen kann. Durch die Räder 28, 29 und 30 ist damit auf alle Fälle eine zentrische Lage des Wickelkernes l9 gewährleistet.A further chain 24 leads from the intermediate gear l3 to a winding gear 25 with an automatically infinitely variable transmission ratio. From the winding gear 25, a further chain 26 leads to two support wheels 28, 29, which are connected to one another via a chain 27 and rotate in the same direction, on which the winding core l9 is mounted and which - if driven - drive the winding core l9 frictionally in the same direction of rotation. The support of the winding core l9 is supplemented by an essentially freely rotatable guide wheel 30 which can be raised and lowered and, in the lowered position, also interacts with the inside of the winding core l9 and then not only an unwanted lifting of the winding core l9 from one of the carrying wheels 28, 29 prevented, but also to increase the frictional engagement between these and the inside l9a of the winding core l9 can contribute. The wheels 28, 29 and 30 thus ensure a central position of the winding core 19 in all cases.

Es sei nun auf die Fig. 2-4 Bezug genommen. Man erkennt in Fig. 2 das Tragrad 28 sowie das Führungsrad 30, das mit ausgezogenen Linien in der Eingriffslage mit der glatten Innenseite l9a des Wickelkernes dargestellt ist. Ein Teil des Umrisses des Wickels 20 ist strich­punktiert dargestellt. Das Tragrad 28 ist auf einer Wel­le 3l aufgekeilt, die ihrerseits in zwei Wälzlagern 32, 33 drehbar in einem Lagergehäuse 34 gelagert ist. Das Lagergehäuse 34 ist fest an der einen Seite einer lot­rechten Seitenwand 35 des Maschinenrahmens angeflanscht, wobei das vom Tragrad 28 entfernte Ende der Welle diese Wand 35 durchsetzt und die die Ketten 26 und 27 aufneh­menden Kettenräder 36, bezw. 37 aufgekeilt hat. Die La­gerung und Anordnung des Tragrades 29 entspricht jener des Tragrades 28.Referring now to Figs. 2-4. 2 shows the support wheel 28 and the guide wheel 30, which is shown in solid lines in the engagement position with the smooth inside l9a of the winding core. Part of the outline of the winding 20 is shown in dash-dot lines. The carrying wheel 28 is wedged on a shaft 3l, which in turn is rotatably supported in two bearing 32, 33 in a bearing housing 34. The bearing housing 34 is flanged firmly to one side of a vertical side wall 35 of the machine frame, the end of the shaft remote from the support wheel 28 passing through this wall 35 and the chain wheels 36 receiving the chains 26 and 27, respectively. 37 has wedged. The bearing and arrangement of the carrying wheel 29 corresponds to that of the carrying wheel 28.

Das Führungsrad 30 ist ebenfalls auf einer Welle 38 aufgekeilt, die zunächst über ein Pendelwälzlager 39 in einem Lagergehäuse 40 drehbar gelagert ist. Das Lager­gehäuse 40 ist auf einer ringförmigen Platte 4l ange­flanscht, die ihrerseits (Vgl. Fig. 3 und 4) an einem Schlitten 42 verankert ist. Dieser in Fig. 3 durch eine dicke Umrandung hervorgehobene Schlitten 42 ist über Ku­gelbüchsen 43 (Fig. 2) verschiebbar auf zwei parallelen Säulen 44 und 45 geführt, sodass die Lenkachse des La­gergehäuses 40 damit bezüglich des Wickelkernes l9 ra­dial verschiebbar ist, und zwar in einer in der Seiten­wand 35 vorhandenen Aussparung 44ʹ. Zum Heben und zum Senken des Lagergehäuses 40 dient ein Fluidikaggregat 45ʹ, dessen Kolbenstange 46 über ein Kreuzgelenk 47 (Fig. 2) in der Mitte des Schlittens 42 angelenkt ist.The guide wheel 30 is also keyed on a shaft 38, which is first rotatably supported in a bearing housing 40 via a spherical roller bearing 39. The bearing housing 40 is flanged onto an annular plate 4l, which in turn (see FIGS. 3 and 4) is anchored to a carriage 42. This carriage 42, which is highlighted in FIG. 3 by a thick border, can be displaced on two parallel ones via ball bushings 43 (FIG. 2) Columns 44 and 45 guided so that the steering axis of the bearing housing 40 can thus be displaced radially with respect to the winding core 19, specifically in a recess 44ʹ in the side wall 35. A fluidic unit 45 Lag is used to raise and lower the bearing housing 40, the piston rod 46 of which is articulated in the middle of the slide 42 via a universal joint 47 (FIG. 2).

Aus Fig. 3 geht hervor, dass der Schlitten 42 im wesent­lichen U-förmig ist. Er umgreift eine Lagerplatte 48, die ihrerseits durch an gegenüberliegenden Seiten nach­giebige Stifte 49, 50 (Fig. 4) so zwischen den Schenkeln des Schlittens 42 gehalten ist, dass sie sich in Bezug auf den Schlitten 42 nicht in einer zu den Säulen 44, 45 parallelen Richtung bewegen kann, sondern nur rechtwink­lig dazu. Zu diesem Zweck ist an der Platte 48 bei 5l die Kolbenstange 52 eines weiteren Fluidikaggregates 53 angelenkt, dessen Zylinder bei 55 am Ende eines vom Schlitten 42 seitlich abstehenden Auslegers 54 angelenkt ist. Um die Lagerplatte 48 auch gegen ein Verkippen zu sichern, ist an ihrer dem Anlenkpunkt 5l gegenüberlie­genden Seite ein Stift 56 verankert, der in ein am Schlitten 42 befestigtes Führungsstück 57 eingreift.3 that the carriage 42 is substantially U-shaped. It encompasses a bearing plate 48, which in turn is held between the legs of the carriage 42 by pins 49, 50 (FIG. 4) which are flexible on opposite sides so that they do not line up with the columns 44, 45 with respect to the carriage 42 parallel direction, but only at right angles to it. For this purpose, the piston rod 52 of a further fluidic unit 53 is articulated on the plate 48 at 5l, the cylinder of which is articulated at 55 at the end of an arm 54 projecting laterally from the carriage 42. In order to also secure the bearing plate 48 against tilting, a pin 56 is anchored on its side opposite the articulation point 51, which engages in a guide piece 57 fastened to the slide 42.

In der Lagerplatte 48 ist ein weiteres Pendelwälzlager 58 montiert, in dem das vom Führungsrad 30 entfernte Ende der Welle 38 gelagert ist. Da sich die Lagerplatte 48 und damit auch das Pendelwälzlager 58 quer zur Rich­tung der Säulen 44, 45 verschieben lässt, kann die Welle 38 in einem beschränkten Winkelbereich um die Mitte des Pendenwälzlagers 39 verschwenkt werden, oder, mit ande­ren Worten entspricht diese Mitte einer Lenkachse 59, um die das Führungsrad 30 auslenkbar ist. In Fig. 4 ist ausgezogen der Umriss des unausgelenkten Führungsrades 30 dargestellt, strichpunktiert dagegen der Umriss in den beiden möglichen Endlagen der Auslenkung.Another spherical roller bearing 58 is mounted in the bearing plate 48, in which the end of the shaft 38 remote from the guide wheel 30 is mounted. Since the bearing plate 48 and thus also the self-aligning roller bearing 58 can be moved transversely to the direction of the columns 44, 45, the shaft can 38 can be pivoted in a limited angular range around the center of the pivot roller bearing 39, or, in other words, this center corresponds to a steering axis 59 about which the guide wheel 30 can be deflected. 4, the outline of the undeflected guide wheel 30 is shown in full line, whereas the outline is dash-dotted in the two possible end positions of the deflection.

Es sei nun angenommen, dass der Wickelkern l9 so auf die Tragräder 28, 29 aufgesetzt werde, dass die Stirnsei­ten des Wickelkernes l9 die in Fig. 4 mit l9ʹ strich­punktiert angegebene Lage einnehmen. Der Wickelkern l9 sei sodann durch die Tragräder 28, 29 so in Drehung ver­setzt, dass die Innenseite des Wickelkernes, auf die das Führungsrad 30 einwirkt, sich in Richtung des Pfeiles 60 bewege. In axialer Richtung ist der Wickelkern l9 nun noch nicht genau positioniert. Es genügt nun, die Lager­platte 48 in Fig. 4 nach oben zu verschieben, so dass die strichpunktiert angegebene Drehachse des Führungs­rades 30 um wenige Grade im Gegenuhrzeigersinn um die Lenkachse 59 verschwenkt wird, wobei das Führungsrad 30 einen entsprechenden Lenkausschlag erhält. Durch diesen Lenkausschlag erteilt nun das Führungsrad 30 dem Wickel­kern l9 eine Bewegungskomponente in Richtung des Pfeiles 6l in Fig. 4. Der Wickelkern l9 wandert somit während der Drehung in Richtung auf die Seitenwand 35 zu, das heisst auf seine richtige Axiallage.It is now assumed that the winding core l9 is placed on the carrying wheels 28, 29 in such a way that the end faces of the winding core l9 assume the position indicated by dash-dotted lines in FIG. 4 with l9ʹ. The winding core 19 is then set in rotation by the support wheels 28, 29 such that the inside of the winding core, on which the guide wheel 30 acts, moves in the direction of the arrow 60. The winding core 19 is not yet exactly positioned in the axial direction. It is now sufficient to move the bearing plate 48 upward in FIG. 4 so that the axis of rotation of the guide wheel 30 indicated by dash-dotted lines is pivoted counterclockwise by a few degrees about the steering axis 59, the guide wheel 30 receiving a corresponding steering deflection. By means of this steering deflection, the guide wheel 30 now gives the winding core l9 a movement component in the direction of the arrow 6l in FIG. 4. The winding core l9 thus moves toward the side wall 35 during rotation, that is to say to its correct axial position.

Die richtige Axiallage wird nun durch eine kreisbogen­förmige Anschlagschiene 62 bestimmt, die (Siehe Fig. 2) am Lagergehäuse 40 der Welle 38 befestigt und daher mit diesem heb- und senkbar ist, wobei die Anschlagschiene konzentrisch zum aufgelegten Wickelkern ist. Um die Vor­richtung auch für Wickelkerne verschiedener axialer Längen benützen zu können, kann die Anschlagschiene 62 auch längs des Lagergehäuses 40 verschiebbar und fest­stellbar angeordnet werden. Andererseits können anstelle der Anschlagschiene 62 auch frei drehbare Anschlagrollen vorgesehen sein, deren Drehachsen radial zum aufgelegten Wickelkern gerichtet sind.The correct axial position is now determined by an arcuate stop rail 62 which (see FIG. 2) is fastened to the bearing housing 40 of the shaft 38 and can therefore be raised and lowered with it, the stop rail being concentric with the winding core placed thereon. In order to be able to use the device also for winding cores of different axial lengths, the stop rail 62 can also be arranged displaceably and fixably along the bearing housing 40. On the other hand, instead of the stop rail 62, freely rotatable stop rollers can also be provided, the axes of rotation of which are directed radially to the wound core.

Würde die Lagerplatte 48 in Fig. 4 nach unten verscho­ben, das heisst die Drehachse des Führungsrades 30 im Uhrzeigersinn um die Lenkachse 59 verschwenkt, ergäbe sich bei gleichbleibender Bewegungsrichtung (Pfeil 60) des Wickelkernes l9 eine den Pfeil 6l entgegengesetzte Bewegungskomponente, die ihrerseits die Entfernung des Wickelkernes l9 erleichtert.If the bearing plate 48 in FIG. 4 were shifted downwards, that is to say the axis of rotation of the guide wheel 30 was pivoted clockwise about the steering axis 59, this would result in a movement component (arrow 60) of the winding core l9 having the opposite movement component, which in turn the distance of the winding core l9 relieved.

Wenn der Wickelkern l9 seine richtige Axiallage erreicht hat, kann der Lenkausschlag des Führungsrades 30 aufge­hoben werden, sodass die Drehachse des Führungsrades wieder exakt parallel zu jenen der Tragräder 28, 29 ist. Damit unterbleibt die Bewegungskomponente des Pfeiles 6l und auch ein allfälliger Reibungsverlust an der An­schlagschiene 62.When the winding core 19 has reached its correct axial position, the steering deflection of the guide wheel 30 can be canceled so that the axis of rotation of the guide wheel is again exactly parallel to that of the support wheels 28, 29. This prevents the movement component of the arrow 6l and also any loss of friction on the stop rail 62.

Während bei der anhand der Fig. 2-4 gezeigten Ausfüh­rungsform das Führungsrad 30 mit seiner Welle 38 stets frei drehbar ist und der Lenkausschlag des Führungsra­des 30 durch Beaufschlagung des Aggregates 43 erzielt wird, kann der Umstand, dass die Lenkachse 59 ausser­halb der Mittenebene des Führungsrades 30 liegt, dazu ausgenützt werden, dessen Lenkausschlag auch auf andere Weise zu bewirken. Eine solche Ausführungsform ist in Fig. 5 skizziert.While in the embodiment shown in FIGS. 2-4, the guide wheel 30 with its shaft 38 is always freely rotatable and the steering deflection of the guide wheel 30 is achieved by acting on the unit 43, the fact that the steering axis 59 is outside the center plane of the guide wheel 30 lies, are used to effect its steering deflection in other ways. Such an embodiment is outlined in FIG. 5.

Das die Seitenwand 35 durchsetzende Ende der Welle 38 ist hier über ein Wälzlager 63 in einer ähnlich wie die Lagerplatte in bezug auf den Schlitten 42 quer zu den Säulen 44, 45 verschiebbaren Lagerhülse 64 gelagert. Die Welle 38 ist über das Wälzlager 63 verlängert und trägt über ein Kugellager 65 den einen Teil 66 einer elektro­magnetischen Bremse 67, welcher Teil durch einen den Schlitten 42 übergreifenden Führungsbügel 68 gegen Ver­drehung gesichert ist, ohne an einer Querverschiebung gehindert zu sein. Auf dem freien Ende der Welle 38 (rechts in Fig. 5) ist der andere Teil 69 der Bremse 67 aufgekeilt.The end of the shaft 38 passing through the side wall 35 is mounted here via a roller bearing 63 in a bearing sleeve 64 which can be displaced transversely to the columns 44, 45 in a manner similar to the bearing plate with respect to the slide 42. The shaft 38 is extended via the roller bearing 63 and carries a part 66 of an electromagnetic brake 67 via a ball bearing 65, which part is secured against rotation by a guide bracket 68 overlapping the slide 42, without being prevented from being displaced transversely. The other part 69 of the brake 67 is wedged on the free end of the shaft 38 (on the right in FIG. 5).

Solange die Bremse 67 gelüftet ist, bleibt die Welle 38 durch die Wirkung der Stifte 49, 50 achsparallel zu den Drehachsen der Tragräder 28, 29, und dem Wickelkern l9 wird keine axiale Bewegungskomponente vermittelt. Wird aber die Bremse 67 betätigt, bewirkt die Bremsung des Führungsrades 30, dass dieses der Bewegungsrichtung 60 drehenden Wickelkernes l9 folgt und somit den Lenkaus­schlag um die Lenkachse 59 bewirkt. Dabei ist allerdings zu beachten, dass die Bremskraft so zu bemessen ist, dass das Führungsrad 30 nicht an einer Drehung verhin­dert, sondern nur gehemmt wird. Sobald die Bremse wieder gelüftet wird, stellt sich das Führungsrad 30 wieder achsparallel zu den Tragrädern 28, 29.As long as the brake 67 is released, the shaft 38 remains axially parallel to the axes of rotation of the support wheels 28, 29 by the action of the pins 49, 50, and the winding core 19 is not imparted any axial movement component. However, if the brake 67 is actuated, the braking of the guide wheel 30 causes it to move in the direction of movement 60 rotating winding core l9 follows and thus causes the steering deflection about the steering axis 59. It should be noted, however, that the braking force is to be dimensioned such that the guide wheel 30 is not prevented from rotating, but is only inhibited. As soon as the brake is released again, the guide wheel 30 is again axially parallel to the support wheels 28, 29.
