Abstract

A changing poster mounting has a number of posters applied onto a strip wound between parallel rollers (13, 16). At least one of the rollers is bent to counteract the self bending forces dues to the weight of the roller and the tension in the poster strip. This ensures both rollers are parallel and that the poster strip is evenly wound without risk of tearing.

Description

Die Erfindung betrifft eine Plakatwechselvorrichtung mit zumindest zwei zueinander im Wesentlichen parallel auf Abstand angeordneten Wickelwalzen, die in Lagervorrichtungen drehbar gelagert sind und zwischen denen ein Plakatband gespannt ist, das wahlweise auf die eine oder die andere Wickelwalze aufwickelbar ist.The invention relates to a poster changing device with at least two substantially parallel to each other at a distance arranged winding rollers in storage devices are rotatably mounted and stretched between which a poster tape is, optionally on one or the other winding roller is windable.

In vielen Fällen wird in seit langem üblicher Weise ein einzelnes Werbeplakat für längere Zeit auf einer Werbefläche angeordnet und beispielsweise aufgeklebt und ist dann ständig sichtbar. Seit einiger Zeit ist es alternativ bekannt, die Werbeflächen insbesondere an Orten, die von vielen Personen besucht werden, beispielsweise Flughäfen, Bahnhöfe etc., mit sogenannten Plakatwechselvorrichtungen auszustatten. Die Plakatwechselvorrichtungen enthalten mehrere unterschiedliche Werbeplakate, die in einer sich ständig wiederholenden Abfolge nacheinander auf einer für umstehende Personen sichtbaren Werbefläche erscheinen.In many cases, it has become commonplace for a long time individual advertising poster for a long time on a billboard arranged and glued example, and then constantly visible. For some time, it has been known alternatively the advertising space especially in places that many People, such as airports, Railway stations, etc., with so-called billboard changing devices equip. The poster changing devices contain several different billboards that are in a constantly changing repeating sequence one after another on one for bystander People visible advertising space appear.

Eine mögliche konstruktive Ausgestaltung einer Plakatwechselvorrichtung umfasst zwei Wickelwalzen, die parallel zueinander auf Bestand angeordnet und jeweils in synchronisierter Weise angetrieben sind. Zwischen den Wickelwalzen erstreckt sich ein bahnartiges Plakatband, auf das die Werbeplakate nebeneinander aufgedruckt sind. Das Plakatband ist jeweils zum Teil auf eine der Wickelwalzen aufgewickelt und der den Zwischenraum zwischen den Wickelwalzen überspannende Abschnitt des Plakatbandes bildet die Werbefläche und ist für umstehende Personen sichtbar.A possible structural design of a poster changing device includes two winding rollers that are parallel to each other arranged on stock and each in sync Are driven way. Between the winding rollers extends a web-like poster volume on which the billboards printed side by side. The poster band is partly wound up on one of the winding rollers and the spanning the space between the winding rollers Section of the poster tape forms the advertising space and is visible to bystanders.

Zur Änderung des sichtbaren Abschnittes des Plakatbandes und somit zum Wechsel des Werbeplakates werden die Wickelwalzen so angetrieben, dass das Plakatband um ein vorbestimmtes Maß auf die eine Wickelwalze aufgewickelt und gleichzeitig von der anderen Wickelwalze abgewickelt wird.To change the visible section of the poster band and thus to the change of the advertising poster, the winding rollers so driven that the poster band by a predetermined Measure wound on the one winding roller and simultaneously unwound from the other winding roller.

Die Wickelwalzen sind zur Vermeidung von Zwängungsspannungen in statisch bestimmter Weise gelagert. Zu diesem Zweck sind an den stirnseitigen Enden der Wickelwalzen jeweils Lagervorrichtungen üblicherweise in Form von Wälzlagern, z.B. Kugellagern vorgesehen. Jede Wickelwalze unterliegt einer Durchbiegung infolge ihres Eigengewichts, infolge des Gewichts des auf ihr aufgewickelten Plakatbandes und infolge der Zugkräfte, die beim Transport des Plakatbandes auf die Wickelwalze einwirken. Es hat sich gezeigt, dass diese Durchbiegung den Lauf des Plakatbandes nachteilig beeinflusst, was im Folgenden anhand der Fig. 1 erläutert wird.The winding rollers are to avoid restraint stresses Stored in a static manner. To this end are at the front ends of the winding rollers respectively Bearing devices usually in the form of rolling bearings, e.g. Ball bearings provided. Each winding roller is subject a deflection due to its own weight, as a result of the Weight of the wrapped on her poster volume and as a result the tensile forces, the transport of the poster tape on act on the winding roller. It has been shown that this Deflection adversely affects the run of the poster tape, which is explained below with reference to FIG. 1.

Fig. 1 zeigt in schematischer Darstellung eine Wickelwalze 1, die an ihren Stirnseiten jeweils axial nach außen hervorstehende Achsstummel 2 bzw. 3 aufweist, die in jeweils einem Wälzlager 4 bzw. 5 drehbar gelagert sind. Auf die Wickelwalze 1 ist ein nur gestrichelt dargestelltes bahnartiges Plakatband 6 aufwickelbar, das an seinem anderen, nicht dargestellten Ende auf eine gleichartige Wickelwalze aufgewickelt ist. Fig. 1 shows a schematic representation of a winding roller 1, which in each case project axially outwards at their end faces Achsstummel 2 and 3, respectively a rolling bearing 4 and 5 are rotatably mounted. On the winding roller 1 is a web-like only shown by dashed lines Poster tape 6 wound, the other at the other, not shown wound on a similar winding roller is.

Wie Fig. 1 zeigt, biegt sich die Wickelwalze 1 infolge ihres Eigengewichts, infolge des auf ihr befindlichen Plakatbandes 6 sowie gegebenenfalls infolge von Zugkräften, die beim Abziehen des Plakatbandes auf die Wickelwalze einwirken, nach unten durch. Zur Verdeutlichun der Problematik ist die Durchbiegung in Fig. 1 bewusst übertrieben dargestellt.As shown in FIG. 1, the winding roller 1 bends due to their Own weight, as a result of the poster tape on it 6 and, where appropriate, as a result of tensile forces, act on the winding roller when removing the poster tape, down through. To clarify the problem the deflection in Fig. 1 is deliberately exaggerated.

Beim Aufwickeln des Plakatbandes 6 werden im Umschlingungsbereich der Wickelwalze 1 Kräfte W1 auf das Plakatband 6 übertragen. Diese Kräfte W1 sind senkrecht zur Mittelachse M der Wickelwalze 1 gerichtet. Aufgrund der Durchbiegung der Wickelwalze 1 ist deren Mittelachse M jedoch gekrümmt, so dass die Kräfte W1 nicht parallel zur gewünschten Wickelrichtung Ww sind, die der Längsrichtung des Plakatbandes 6 entspricht. Auf diese Weise entstehen resultierende Kraftkomponenten WR in Richtung der Mitte der Wickelwalze. Dies führt dazu, dass das Plakatband dazu neigt, in der Mitte der Wickelwalze 1 zusammenzulaufen, was zu einem Übereinanderschieben der zusammengeklebten Plakatkomponenten an den Klebenähten in Längsrichtung oder aber zu Scherbelastungen des Plakatbands 6 führen kann, durch die sich Risse in dem Plakatband entwickelt können.When winding the poster tape 6 forces W 1 are transmitted to the poster belt 6 in the wrap area of the winding roller. These forces W 1 are directed perpendicular to the central axis M of the winding roller 1. Due to the deflection of the winding roller 1 whose central axis M is curved, however, so that the forces W 1 are not parallel to the desired winding direction W w , which corresponds to the longitudinal direction of the poster belt 6. In this way, resulting force components W R arise in the direction of the center of the winding roller. As a result, the poster tape tends to converge in the center of the winding roller 1, which may result in the adhering of the glued poster components to the adhesive seams in the longitudinal direction or to shear stresses on the poster tape 6, which may cause cracks in the poster tape.

Der Erfindung liegt die Aufgabe zugrunde, eine Plakatwechselvorrichtung der genannten Art zu schaffen, bei der ein gleichmäßiges Aufwickeln des Plakatbandes gewährleistet ist.The invention is based on the object, a poster changing device of the kind mentioned above, in which one ensures uniform winding of the poster tape is.

Diese Aufgabe wird bei einer Plakatwechselvorrichtung der genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass in zumindest eine der Wickelwalzen mittels der zugeordneten Lagervorrichtung ein Vorspann-Biegemoment einbringbar ist, das dem Biegemoment der Wickelwalze infolge Eigengewicht und Belastung entgegenwirkt.This task is in a billboard changing the mentioned type with the characterizing features of the claim 1 solved. It is envisaged that in at least one of the winding rollers by means of the associated storage device a biasing bending moment can be introduced that the Bending moment of the winding roller due to its own weight and load counteracts.

Die Grundidee der Erfindung liegt darin, die Durchbiegung der Wickelwalze zu vermeiden oder zu verringern, indem in die Wickelwalze ein gerichtetes Vorspann-Biegemoment eingebracht wird, das das Biegemoment, das infolge des Eigengewichts der Wickelwalze und infolge der Belastung durch das aufgewickelte Plakatband auftritt, zumindest annähernd oder vollständig ausgleicht oder sogar überkorrigiert. Auf diese Weise sind die zur Mitte der Wickelwalze gerichteten Kraftkomponenten WR (siehe Fig. 1) entweder vermieden oder zu den äußeren stirnseitigen Enden der Wickelwalze gerichtet, wodurch das Plakatband in geringem Maße in Querrichtung vorgespannt ist.The basic idea of the invention is to avoid or reduce the deflection of the winding roller by introducing into the winding roller a directed pretensioning bending moment which at least causes the bending moment which occurs as a result of the self-weight of the winding roller and as a result of the loading by the wound-up poster tape approximately or completely compensated or even overcorrected. In this way, directed to the center of the winding roller force components W R (see Fig. 1) are either avoided or directed to the outer end ends of the winding roller, whereby the poster tape is biased to a small extent in the transverse direction.

Die Lagervorrichtungen sind vorzugsweise in an sich bekannter Weise an den stirnseitigen Enden der Wickelwalze angeordnet. Dabei ist in bevorzugter Ausgestaltung der Erfindung vorgesehen, dass jede Lagervorrichtung zwei in Axialrichtung der Wickelwalze beabstandete Lagerteile aufweist, wobei die Lagerteile jeweils ein Wälzlager oder ein Kugellager sein können. Die Wickelwalze ist somit an ihren beiden Enden jeweils über zwei Wälzlager oder zwei Kugellager gelagert. Durch diese überbestimmte Lagerung ist es möglich, dass Vorspann-Biegemoment in die Wickelwalze einzubringen.The storage devices are preferably known per se Way arranged at the front ends of the winding roller. It is in a preferred embodiment of the invention provided that each bearing device two in the axial direction the winding roller has spaced bearing parts, wherein the bearing parts each have a rolling bearing or a ball bearing could be. The winding roller is thus at its two Ends via two roller bearings or two ball bearings stored. This overdetermined storage makes it possible to introduce the pretensioning bending moment into the winding roller.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Größe und/oder die Richtung des Vorspann-Biegemomentes veränderbar ist, was beispielsweise dadurch geschehen kann, das die beiden Lagerteile relativ zueinander verstellbar sind. In a preferred embodiment of the invention is provided that the size and / or the direction of the prestressing bending moment is changeable, which is done by, for example that can be the two bearing parts relative to each other are adjustable.

Die Lagervorrichtungen an den Enden der Wickelwalze können entweder außerhalb oder auch innerhalb der Wickelwalze angeordnet sein. Wenn die Lagervorrichtungen außerhalb der Wickelwalze angeordnet sind, ist vorzugsweise vorgesehen, dass die Wickelwalze an ihren stirnseitigen Enden jeweils einen axialen Achsstummel aufweist, der in der zugeordneten Lagervorrichtung drehbar gelagert ist. Da der Achsstummel die beiden Lagerteile der Lagervorrichtung durchdringt, kann die Neigung des Achsstummels durch gegenseitige Verstellung der Lagerteile verändert und eingestellt werden, so dass der Lagerwalze ein gewünschtes Vorspann-Biegemoment aufgebracht werden kann.The storage devices at the ends of the winding roller can arranged either outside or inside the winding roller be. If the storage devices outside the Winding roller are arranged, is preferably provided that the winding roller at their front ends in each case having an axial stub axle, in the associated Bearing device is rotatably mounted. Since the stub axle penetrates the two bearing parts of the bearing device, can the inclination of the stub axle by mutual adjustment the bearing parts are changed and adjusted, such that the bearing roller has a desired pretensioning bending moment can be applied.

Die genannten Probleme treten insbesondere dann auf, wenn die Wickelwalzen im Wesentlichen horizontal ausgerichtet sind so dass sich die Erfindung auf eine entsprechende Ausgestaltung vorzugsweise bezieht.The problems mentioned occur in particular when the winding rollers are aligned substantially horizontally are so that the invention to a corresponding embodiment preferably relates.

Fig. 2 zeigt eine Plakatwechselvorrichtung 10, die in einem nur angedeuteten Gehäuse 11 aufgenommen ist und zwei horizontal ausgerichtete, in gegenseitigem Abstand angeordnete Wickelwalzen 13 und 16 umfasst, die in beide Drehrichtungen angetrieben sind, wie durch die Doppelpfeile R angedeutet ist. Die parallel verlaufenden Wickelwalzen 13 und 16 besitzen jeweils an ihren stirnseitigen Enden einen axial hervorstehenden, zentrischen Achsstummel 14 bzw. 17, der jeweils in einer Lagervorrichtung 15 bzw. 18 drehbar gelagert ist. Zwischen den Wickelwalzen 13 und 16 erstreckt sich ein bandartiges Plakatband 19, auf dem mehrere nicht dargestellte Werbeplakate angebracht oder aufgedruckt sind. Das Plakatband 19 ist zu einem Teil auf der gemäß Fig. 2 oberen Wickelwalze 13 und zu einem anderen Teil auf der unteren Wickelwalze 16 aufgewickelt. Der den Zwischenraum zwischen den Wickelwalzen 13 und 16 überspannende Abschnitt des Plakatbandes 19 ist durch ein angedeutetes Fenster 12 des Gehäuses 11 sichtbar.Fig. 2 shows a poster changing device 10, which in a only indicated housing 11 is added and two horizontally aligned, spaced apart Winding rollers 13 and 16 includes, in both directions of rotation are driven, as indicated by the double arrows R. is. The parallel winding rollers 13 and 16 have each at its front ends an axial protruding, central stub axle 14 and 17, the each rotatably mounted in a bearing device 15 and 18, respectively is. Between the winding rollers 13 and 16 extends a ribbon-like poster volume 19, on the several not displayed advertising posters are attached or printed. The poster tape 19 is to a part on the according to FIG. 2 upper winding roller 13 and to another part on the lower Winding roller 16 wound. The the gap between the winding rollers 13 and 16 spanning section of the poster band 19 is indicated by an indicated window 12 the housing 11 visible.

Um den sichtbaren Abschnitt des Plakatbandes 19 zu verändern und somit einen Wechsel des im Fenster 12 sichtbaren Werbeplakats herbeizuführen, werden die beiden Wickelwalzen 13 und 16 in synchronisierter Weise so angetrieben, dass das Plakatband 19 um ein vorbestimmtes Maß auf eine der Wickelachsen aufgewickelt und gleichzeitig von der anderen Wickelachse abgewickelt wird.To change the visible portion of the poster band 19 and thus a change of visible in the window 12 Advertising posters bring about the two winding rollers 13 and 16 are driven in a synchronized manner so that the poster tape 19 by a predetermined amount on one of the winding axes wound up and at the same time from the other Winding axle is unwound.

Wie bereits anhand der Fig. 1 erläutert wurde, unterliegen die Wickelwalzen infolge ihres Eigengewichts sowie ihrer Belastung infolge des aufgewickelten Plakatbandes 19 einer Durchbiegung. Diese kann mittels der Lagervorrichtungen 15 und 18 kompensiert werden. Wie Fig. 3 zeigt, in der nur die obere Wickelwalze 13 der Plakatwechselvorrichtung 10 gemäß Fig. 2 dargestellt ist, umfassen die Lagervorrichtungen 15 jeweils zwei axial beabstandete Lagerteile 15a und 15b, die jeweils von einem Wälzlager oder einem Kugellager gebildet sind. Die Achsstummel 14 sind jeweils in beiden Lagerteilen 15a und 15b gelagert. Dabei sind die Lagerteile 15a und 15b relativ zueinander verstellbar, wie durch die Doppelpfeile H und V angedeutet ist. Durch entsprechende Ausrichtung der beiden Lagerteile 15a und 15b relativ zueinander kann die Neigung der Achsstummel 14 festgelegt werden, was wiederum dazu führt, dass der Wickelwalze 13 ein Vorspann-Biegemoment aufgezwängt wird, dass dem Biegemoment der Wickelwalze infolge Eigengewicht und Belastung entgegenwirkt. Auf diese Weise ist es möglich, dass infolge Eigengewicht und Belastung entstehende Biegemoment teilweise oder vollständig auszugleichen oder sogar in der Wickelwalze ein resultierendes Biegemoment zu erzeugen, so dass das Plakatband 19 in geringem Maße in Querrichtung vorgespannt ist, wie bereits im Zusammenhang mit Fig. 1 erläutert wurde.As already explained with reference to FIG. 1, subject the winding rollers due to their own weight as well as their Stress due to the wound-up poster tape 19 a Deflection. This can be done by means of the storage devices 15th and 18 are compensated. As shown in FIG. 3, in which only the upper winding roller 13 of the poster changing device 10 according to 2, the storage devices 15 comprise in each case two axially spaced bearing parts 15a and 15b, the each formed by a rolling bearing or a ball bearing are. The stub axles 14 are each in both bearing parts 15a and 15b stored. In this case, the bearing parts 15a and 15b relative to each other adjustable, as by the double arrows H and V is indicated. By appropriate alignment of two bearing parts 15 a and 15 b relative to each other, the Inclination of the stub axle 14 are fixed, which in turn causes the winding roller 13 a biasing bending moment is squeezed that the bending moment of the winding roller counteracts self-weight and load. In this way it is possible that due to dead weight and load resulting bending moment partially or completely compensate or even in the winding roller a resulting To create bending moment so that the poster tape 19 is biased to a slight extent in the transverse direction, as already explained in connection with FIG. 1.

Die Ausgestaltung gemäß Fig. 4 unterscheidet sich von der Ausgestaltung gemäß Fig. 3 dadurch, dass die Lagerteile 15a und 15b innerhalb der Wickelwalze 13 angeordnet sind und auf einem Achsstummel 20 sitzen, der gestellfest gehalten ist.The embodiment of FIG. 4 differs from the Embodiment according to FIG. 3 in that the bearing parts 15a and 15b are disposed within the winding roller 13 and sit on a stub axle 20, which held the frame is.
