Abstract

The invention concerns a roller-band system designed for the display of information, etc., the system having two winder rollers (1, 2), disposed substantially parallel to each other a certain distance apart, and a roller band (5). The aim of the invention is to prevent, by simple measures, the roller band (5) from straying from its normal position as it is wound forward or back. This is achieved by mounting at least one of the rollers (1, 2) so that it can be displaced in the longitudinal direction. The displaceable roller is moved by servo drive working in conjunction with remote sensors (17) which detect any excursion of the roller band from its normal position, thus correcting any tendency to stray from this position.

Beschreibungdescription

Die Erfindung bezieht sich auf einen Rollbandapparat zum Darstellen von Informationen od.dgl. mit zwei einander im wesentlichen parallel beabstandet gegenüberliegenden Wickelwalzen und einem Rollband, insbesondere aus einer Kunstoff-Folie, das wahlweise jeweils von einer Wickelwalze ab- und auf die andere Wickelwalze aufgewickelt werden kann, und mit einer Einrichtung zum Verhindern des Auswanderns des Rollbandes aus seiner Normallage.The invention relates to a roller belt apparatus for displaying information or the like. with two mutually substantially parallel spaced winding rollers and a roller conveyor, in particular made of a plastic film, which can optionally be wound from one winding roller and onto the other winding roller, and with a device for preventing the migration of the roller conveyor from its normal position .

Solche Rollbandapparate sind in der Vergangenheit vielfach genutzt worden, um Werbung und Informationen wechselnder Art sichtbar zu machen. Sobald diese Rollbandapparate eine gewisse Größe überschreiten, macht es sich negativ bemerkbar, wenn die Rollbänder seitlich aus ihrer Normalläge auswandern. Ein solches Auswandern führt zu einer besonderen Beanspruchung der Bandkanten des Rollbandes und schließlich zu dessen Zerstörung. Diese Belastung der Bandkanten ist u.a. deswegen ungünstig, da man das Rollband vielfach nur als Trägerband verwenden will, auf dem die einzelnen Informationsträger auswechselbar befestigt werden. Es kommt daher darauf an, daß das Rollband selbst möglichst langlebig ist.Roll tape devices of this type have been used many times in the past to make advertisements and information of different types visible. As soon as these conveyor belts exceed a certain size, it has a negative effect when the conveyor belts move out of their normal position to the side. Such emigration leads to a particular stress on the belt edges of the roller belt and ultimately to its destruction. This load on the belt edges is therefore unfavorable, since you often want to use the roll tape only as a carrier tape, on which the individual information carriers are exchangeably attached. It is therefore important that the roller belt itself is as long-lasting as possible.

Aus der DE-PS 17 86 332 ist ein Apparat zum Antreiben eines endlosen, über Trommeln geführten Bandes bekannt. Um ein Auswandern des Endlosbandes zu verhindern, ist eine der UmleiΛtrommeln aus ihrer senkrechten Achslage kippbar. Zum Steuern der Kippbewegung sind in den Bandkanten Vorsprünge vorgesehen, die mit Tastern und zugehörigen Schaltern zusammenarbeiten. Obgleich man mit dieser Vorrichtung ein Auswandern des Bandes in Grenzen halten kann, werden die Bandkanten nicht geschont. Insbesondere bei der Verwendung dünner Kunstoff-Folien als Rollbänder eignet sich, das bekannte Verfahren nicht mehr.From DE-PS 17 86 332 an apparatus for driving an endless belt guided over drums is known. To prevent the endless belt from migrating, one is the diversion drums can be tilted from their vertical axis position. To control the tilting movement, projections are provided in the band edges, which cooperate with buttons and associated switches. Although it is possible to keep the tape from moving within limits with this device, the tape edges are not spared. The known method is no longer suitable, in particular when using thin plastic films as conveyor belts.

Es ist Aufgabe der vorliegenden Erfindung, einen Rollbandapparat der eingangs genannten Art so weiterzubilden, daß auf konstruktiv einfache Weise ein Auswandern des Rollbandes aus seiner Normallage auch bei großen Abmessungen des Rollbandapparates verhindert werden kann, ohne daß die Bandkanten des Rollbandes einer übermäßigen Beanspruchung ausgesetzt werden.It is an object of the present invention to develop a conveyor belt apparatus of the type mentioned at the outset in such a way that, in a structurally simple manner, migration of the conveyor belt from its normal position can be prevented even with large dimensions of the conveyor belt apparatus without the ribbon edges of the conveyor belt being subjected to excessive stress.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens eine der Wickelwalzen in Achsrichtung verschiebbar gelagert ist, und daß die Einrichtung einen Stellantrieb für das Verschieben der Wickelwalzen, mindestens einen berührungslosen Sensor zum Erfassen von Auswanderungsbewegungen des Rollbandes und eine Regelung umfaßt, die in Abhängigkeit des vom Sensor gelieferten Signals den Stellantrieb der Wickelwalze betätigt.This object is achieved in that at least one of the winding rollers is mounted displaceably in the axial direction, and that the device comprises an actuator for moving the winding rollers, at least one non-contact sensor for detecting emigration movements of the conveyor belt and a control system which depends on the Sensor delivered signal actuated the actuator of the winding roller.

Diese Lösung hat den Vorteil, daß die Wickelwalze je nach Art der Auswanderungsbestrebungen des Rollbandes mehr oder weniger stark seitlich zur Bewegungsrichtung des Rollbandes verschoben wird. Auf diese Weise kann das Auswandern des Rollbandes schonend korrigiert werden, ohne daß die Bandkanten übermäßig beansprucht werden. Ferner ist keine mechanische Führung der Bandkanten erforderlich; der Sensor ist lediglich dafür vorgesehen, um Abweichungen des Bandes aus seiner Normalläge zu erkennen, um diese an die Regelung weiterzumeiden.This solution has the advantage that the winding roller is displaced more or less laterally to the direction of movement of the roller belt depending on the type of migration efforts of the roller belt. In this way, the emigration of the conveyor belt can be gently corrected without the belt edges being excessively stressed. Furthermore, no mechanical guidance of the band edges is required; the sensor is only intended to detect deviations of the tape from its normal position in order to avoid this to the regulation.

Obgleich es ausreicht, wenn eine der beiden Wickelwalzen verschiebbar gelagert ist, können in vorteilhafter Weise auch beide Wickelwalzen verschiebbar gelagert sein, wodurch die Regelung vereinfacht wird.Although it is sufficient if one of the two winding rollers is slidably mounted, advantageously both winding rollers can also be slidably mounted, which simplifies the control.

Als besonders günstig hat es sich herausgestellt, wenn der Sensor ein optischer Sensor, vorzugsweise eine Lichtschranke, ist. In diesem Zusammenhang ist es günstig, wenn der Sensor an einem Gestell im Bereich der Bandkante des Rollbandes vorgesehen ist. Es können bei dieser Ausbildung des Sensors an beiden Bandkanten des Rollbandes Lichtschranken vorgesehen sein. Es ist besonders dann günstig, wenn beide Wickelwalzen mit einem Stellantrieb versehen sind. Bei Änderung der Laufrichtung des Rollbandes braucht die Regelung dann lediglich auf den jeweils anderen Sensor und den jeweils anderen Stellantrieb umzuschalten, wobei die Art der Regelung gleich bleibt.It has turned out to be particularly favorable if the sensor is an optical sensor, preferably a light barrier. In this context, it is advantageous if the sensor is provided on a frame in the area of the belt edge of the roller belt. With this configuration of the sensor, light barriers can be provided on both belt edges of the roller belt. It is particularly advantageous if both winding rollers are provided with an actuator. When changing the running direction of the conveyor belt, the control then only needs to switch to the other sensor and the other actuator, the type of control remaining the same.

Ein Ausfühirungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:An exemplary embodiment of the invention is explained in more detail below with reference to a drawing. Show it:

Fig. 1 in einer schematischen Darstellung die Rückansicht eines erfindungsgemäßen Rollbandapparates bei geöffnetem Gehäuse,1 is a schematic representation of the rear view of a roller belt apparatus according to the invention with the housing open,

Fig. 2 eine Detailansicht einer Verschiebeeinheit.Fig. 2 is a detailed view of a displacement unit.

In Fig. 1 ist schematisch ein Rollbandapparat in einem an der Rückseite aufgeschnittenen Gehäuse dargestellt. Der Rollbandapparat umfaßt eine obere Wickelwalze l und eine dazu parallel und mit Abstand angeordnete untere Wickelwalze 2. Beide Wickelwalzen 1 und 2 sind jeweils über eine Zahnradpaarung 4 bzw. 4' mit einem Antriebsmotor 3 bzw. 3' verbunden. Auf den beiden Wickelwalzen 1 und 2 ist ein Rollband 5 aufgewickelt, von dem in Fig. 1 nur die Rückseite zu sehen ist. Das Rollband kann von der oberen Wickelwalze 1 auf die untere Wickelwalze 2 und umgekehrt aufgewickelt werden.In Fig. 1, a roller conveyor is shown schematically in a cut open housing on the back. The roller belt apparatus comprises an upper winding roller 1 and one to this, parallel and spaced lower winding roller 2. Both winding rollers 1 and 2 are each connected via a gear pair 4 or 4 'to a drive motor 3 or 3'. On the two winding rollers 1 and 2, a roller belt 5 is wound, of which only the back can be seen in FIG. 1. The roller belt can be wound up from the upper winding roller 1 to the lower winding roller 2 and vice versa.

Bei dem hier gezeigten Ausführungsbeispiel sind beide Wickelwalzen 1 und 2 in Richtung ihrer Achse 6 bzw. 6' und damit quer zur Aufwickelrichtung des Rollbandes 5 verschiebbar gelagert. Die Zahnradpaarungen 4 bzw. 4' tragen dieser Verschiebemöglichkeit dadurch Rechnung, daß das Ritzel entsprechend lang ausgebildet ist.In the exemplary embodiment shown here, both winding rollers 1 and 2 are mounted so as to be displaceable in the direction of their axes 6 and 6 'and thus transversely to the winding direction of the roller belt 5. The gear pairs 4 and 4 'take this displacement possibility into account in that the pinion is designed to be correspondingly long.

Der Aufbau einer solchen Verschiebeeinrichtung 7 wird im folgenden näher anhand der Fig. 2 beschrieben. Dort ist erkennbar, daß die Wickelwalze an dem dem Antriebsmotor abgewandten Ende auf einem gehäusefest angebrachten Achsstummel δ in Richtung des Doppelpfeiles S verschiebbar und drehbar gelagert ist. Auf dem Achsstiimmel 8 sitzt in Fortsetzung der Wickelwalze 2 eine an dieser drehfest und auf dem Achsstiimmel verschiebbar und verdrehbar angeordnete Stellhülse 9, auf welcher über ein Kugellager 10 ein Verstellarm 11 verdrehbar, nicht jedoch verschiebbar gelagert ist.The structure of such a displacement device 7 is described in more detail below with reference to FIG. 2. It can be seen there that the winding roller is mounted on the end facing away from the drive motor on a shaft stub δ fixed to the housing in the direction of the double arrow S so that it can be moved and rotated. In continuation of the winding roller 2, an adjusting sleeve 9 is arranged on the axle shaft 8 and is rotatably mounted on the axle shaft and on which an adjusting arm 11 can be rotated, but is not slidably mounted, via a ball bearing 10.

An seinem der Wickelwalze 2 abgewandten Ende besitzt der Verstellarm 11 eine Durchgangsbohrung 12 mit einem Innengewinde, die sich parallel zum Achsstummel 8 erstreckt.At its end facing away from the winding roller 2, the adjusting arm 11 has a through hole 12 with an internal thread, which extends parallel to the stub shaft 8.

Durch die Durchgangsbohrung 12 hindurch erstreckt sich eine in dem Gehäuse drehbar gelagerte Gewindespindel 13, die auf der Welle eines Verstellmotors 14 angebracht ist, welcher selbst wiederum am Gehäuse befestigt ist.A extends through the through hole 12 in the housing rotatably mounted threaded spindle 13, which is mounted on the shaft of a servomotor 14, which in turn is attached to the housing.

Eine ähnliche Verschiebeeinrichtung 7' ist an der oberen Wickelwalze 1 vorgesehen, wie aus Fig. 1 hervorgeht.A similar displacement device 7 'is provided on the upper winding roller 1, as can be seen from FIG. 1.

Die Versteilmotoren 14 bzw. 14' beider Verschiebeeinrichtungen 7 sind an eine Regeleinheit 15 angeschlossen. Ferner sind im Bereich der Bandkanten 16 des Rollbandes 5 optische Sensoren 17 angebracht, die einen seitlichen Versatz der Bandkanten 16 und damit des Rollbandes 5 registrieren. Beide Sensoren 17 sind ebenfalls mit der Regeleinheit 15 verbunden. Schließlich sind auch noch die Antriebsmotoren 3 und 3' der beiden Wickelwalzen 1 und 2 an die Regeleinheit 15 angeschlossen. Der Übersichtlichkeit halber nicht dargestellt ist ein Bedienpult, welches ebenfalls an die Regeleinheit 15 angeschlossen ist.The adjusting motors 14 and 14 'of both displacement devices 7 are connected to a control unit 15. Furthermore, 5 optical sensors 17 are attached in the area of the tape edges 16 of the roll tape 5, which register a lateral offset of the tape edges 16 and thus of the roll tape 5. Both sensors 17 are also connected to the control unit 15. Finally, the drive motors 3 and 3 'of the two winding rollers 1 and 2 are also connected to the control unit 15. A control panel, which is also connected to the control unit 15, is not shown for the sake of clarity.

Im folgenden wird nun die Wirkungs- und Funktionsweise des erfindungsgemäßen Rollbandapparates näher erläutert.The operation and functioning of the roller conveyor apparatus according to the invention will now be explained in more detail below.

Über das nicht näher dargestellte Bedienpult kann der Regeleinheit nun der Befehl gegeben werden, daß sich das Rollband nach oben bewegen soll und somit von der oberen Wickelwalze 1 aufgerollt wird. Nun kann es hierbei aufgrund der Größenabmessungen des Rollbandapparates zum seitlichen Auswandern des Rollbandes 5 kommen. Ein solches seitliches Auswandern des Rollbandes wird durch die Sensoren 17 registriert, woraufhin entsprechend einem vorbestimmten Progrcimm entweder der Verstellmotor 14 für die untere Wickelwalze 2 oder der Verstellmotor 14' für die obere Wickelwalze 1 betätigt wird, um dem Auswandern des Rollbandes entgegenzuwirken. Eine Möglichkeit der Regelung besteht z.B. darin, daß beim Aufwickeln des Rollbandes 5 auf die obere Wickelwalze die untere Wickelwalze 2 seitlich so verschoben wird, daß die Bandkanten 16 des Rollbandes 5 stets in einem bestimmten Soll-Bereich geführt werden, dessen Einhaltung durch die Sensoren 17 überwacht und durch entsprechende Signalgabe der Regeleinheit 15 gewährleistet ist. Eine andere Möglichkeit wäre die, beim Aufwickeln auf die obere Wickelwalze 1 diese in die gleiche Richtung zu verschieben, in der das Rollband 5 auswandert. Aufgrund dieser unterschiedlichen Steuerung-smöglichkeiten ist es auch denkbar, daß lediglich eine der Wickelwalzen verschieblich angeordnet ist, während die andere Wickelwalze starr ist. Hat man jedoch wie bei dem hier gezeigten Ausftϊhrungsbeispiel zwei verschiebbare Wickelwalzen zur Verfügung, kann das Regelungsprog^ε_mm ein acher gestaltet sein. The control unit can now be given the command that the roller conveyor should move upward and thus be rolled up by the upper winding roller 1 via the control panel (not shown in more detail). Now, due to the size dimensions of the roller belt apparatus, the roller belt 5 can migrate sideways. Such lateral migration of the roller belt is registered by the sensors 17, whereupon, according to a predetermined program, either the adjusting motor 14 for the lower winding roller 2 or the adjusting motor 14 'for the upper winding roller 1 is actuated to prevent the migration of the Counteracting the conveyor belt. One possibility of regulation consists, for example, in that when the roller belt 5 is wound onto the upper winding roller, the lower winding roller 2 is laterally displaced in such a way that the belt edges 16 of the roller belt 5 are always guided in a certain desired range, the observance of which by the sensors 17 monitored and guaranteed by appropriate signaling of the control unit 15. Another possibility would be to move the upper winding roller 1 in the same direction in which the roller belt 5 migrates when winding it up. Because of these different control options, it is also conceivable that only one of the winding rollers is arranged displaceably, while the other winding roller is rigid. If, however, as in the embodiment shown here, you have two slidable winding rollers available, the control program ^ ε_mm can also be designed as one.
