Definitions
- the invention relates to a device for displaying announcements, in particular prices in numerical form.
- AT-B-388253 is a generic device for displaying announcements, in particular prices in numerical form, previously known.
- a display tape is provided for each digit of a price, which is partially rolled up on two winding rollers arranged parallel to each other and whose surface between the winding rollers forms the display surface.
- Each winding roller is designed as a hollow roller and is connected via an electromagnetic clutch to a drive shaft which is connected to the drive pinion of a central drive motor via chain wheels and chains arranged at the ends thereof.
- four display tapes with four winding rollers each running on one plane and parallel to one another are provided on a display device for four digit positions.
- An adjustment of the numerical display of a display tape is carried out by driving the central drive motor and actuating the electromagnetic clutch of the winding roller on which the respective display tape must be wound in order to change the numerical display.
- a braking bearing is assigned to each winding roller, so that the display tape remains tensioned on a winding roller during winding.
- the invention is therefore based on the object to provide a device for displaying announcements of the generic type, which is structurally simple and in which the wound on the winding rollers and unwound from these display tape is constantly kept under constant belt tension.
- a drive motor is assigned to each winding roller, whereby the technical and constructive outlay of the display device is significantly reduced. Furthermore, the drive motor winding the display tape onto the one winding roller is operated at a higher speed than the drive motor unwinding the display tape from the other winding roller. As a result, a functionally advantageous operating state is achieved, which is characterized in that the faster rotating winding drive motor and the slower rotating unwinding drive motor are forced into a synchronous operation at constant belt tension via the winding or unwinding display tape.
- the unwinding drive motor is operated at a lower speed than the winding motor.
- the winding drive motor thus pulls the unwinding drive motor over the winding roller assigned to it via the winding roller assigned to it and the display tape and thus keeps the display tape in synchronous operation with constant belt tension.
- the two drive motors are switched off simultaneously.
- the display band remains taut because the possible overrun of the two drive motors by the display band is necessarily the same.
- the drive motors are designed as electric motors, the voltage of which is regulated to effect the desired different drive speeds.
- the voltage of the electric motor winding the display tape onto a winding roller is the supply voltage of the operating network and the voltage of the electric motor unwinding the display tape from the other winding roller is lower than the supply voltage of the operating network.
- the two electric motors are DC motors connected in parallel, in particular geared motors, to each of which resistors are connected in series and diodes connected in parallel to them with an opposite blocking direction. By simply reversing the polarity of the supply voltage of the two DC motors, one or the other winding roller can be switched as a winding roller and the other as a winding winding roller.
- the use of geared motors with high gear ratios prevents a return of the winding rollers, whereby a constant sliver tension is achieved at a standstill.
- the electric motors are designed in particular as geared motors built into the winding rollers.
- the device comprises a box-shaped housing 1, in which two groups of three winding units 2 each are mounted on the front side and on the rear side, not shown, each of which is formed from an upper winding roller 3 and a lower winding roller 4 arranged at a distance from this, on which a display tape 5, in particular a plastic tape made of translucent or transparent material, is wound with its two ends or wound up and unwound. Above each group of winding units 2 there are display areas 6 for product names such as "Diesel" and "Super”. The symbols on the individual display tapes, in particular numbers, are not shown.
- the housing 1 comprises between each winding unit 2 or between two winding rollers 3, 3' arranged one behind the other in an axis Side plate 10, on which for each winding roller 3, 3 'a bearing ring 12 with a bronze spring washer 13 interposed, which also serves to protect the supply cable to the motor 8, is flanged.
- the flanges are carried out by screw connection elements 11.
- the peripheral surfaces of the bearing rings 12 are circular and are arranged concentrically to the axis and guide the tubular winding rollers 3, 3 ', which are provided at the front end with flanges 14, which define a lateral limitation for each form wound display tape 5.
- a geared motor 8 is flanged onto a bearing ring 12 by means of a motor plate 9 and several stud bolts 15, so that the geared motor 8 is carried by the side plates 10 of the housing 1.
- a driving disk 17 is placed in a rotationally fixed manner, which exactly fills the inside diameter of the tubular winding roller 3, 3 'with its outer surface.
- the drive plate 17 is positively connected to the tubular winding roller 3, 3 'via stud screws 18.
- the associated tubular winding roller 3, 3 ′ is thus driven via the driving disk 17, which can be rotated on the peripheral surfaces of two bearing rings 12 and is guided on the side plates 10 via the bronze spring washers 13.
- 2 and 3 tension rods 19 and spacer tubes 20 and in the vertical direction variable connecting struts 21 are provided for connecting the individual side plates 10, which can be seen in FIGS. 1, 4 and 5.
- both side plates 10 are at a distance from the axes of the two winding rollers 3, 3 'deflection rollers 22 with lateral guide bushes 23, around which the display tape 5 is guided and between which the display tape 5 is freely visible.
- Each of the display tapes 5 drawn off from the upper side of the winding rollers 3, 4 are provided with lateral perforations 24 which circulate in the area of a tape scan 25 shown on the lower side plate 10 in FIG. 5 and thereby the exact positioning of the Display tape 5 and thus the character located on this is set.
- the plastic display tapes 5 run in a manner not shown behind plexiglass covers held in the housing 1 and are illuminated from the inside via TL tubes 26 attached between the front and rear winding units 2.
- the display tapes 5 of the front and rear winding units 2 are each guided behind the front or rear plexiglass cover.
- the upper and lower winding rollers 3, 4 of the front and rear winding units 2 are each with their axes on a common horizontal plane.
- the axes of the upper and lower winding rollers 3, 4; 3 ′′, 4 ′′ are offset vertically from one another and the display tape 5, of the rear winding unit 2 ′ provided with a larger center distance, is guided forward and extends parallel to and at a short distance in front of the display belt 5 of the front winding unit 2. Additional deflection rollers 22 'are therefore required for the winding belt 5'.
- the front display tape 5 'of the rear winding unit 2' is completely or partially transparent, so that the symbols located on the rear display tape 5 of the front winding unit 2 can be seen through the front display belt 5 '.
- the geared motors 8, 8 ' are DC motors, to which in each case resistors 27, 27 'are connected in series and to them diodes 28, 28' connected in parallel with the reverse blocking direction.
- diode 28 of the geared motor 8 is conductive, whereas the diode 28 'of the geared motor 8' blocks.
- the geared motor 8 is thus operated with the supply voltage of the operating network applied to the connection points 29, 30.
- the geared motor 8 ' is operated only with the supply voltage of the operating network via the resistor 27', ie with a lower voltage, so that the drive speed of the geared motor 8 'is lower than the drive speed of the geared motor 8.
- the geared motor 8, the z. B. is arranged in the upper winding roller 3 of a winding unit 2, winds up the associated display tape 5, whereas the then arranged in the lower winding roller 4 of the same winding unit 2 gear motor 8 'unwinds the display tape 5 at a lower speed, so that the display tape 5 constantly is kept under tension.
- the two geared motors 8,8 ' are operated in opposite directions. After the desired position of the display tape 5 has been reached, both geared motors 8, 8 'are switched off by a manual control device or a microprocessor circuit.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Anzeige von Ankündigungen, insbesondere von Preisen in Ziffernform.The invention relates to a device for displaying announcements, in particular prices in numerical form.
Vor allem bei Tankstellen besteht die Notwendigkeit, den angezeigten Treibstoffpreis leicht ändern zu können. In Zukunft wird dies an einem Tage sogar mehrmals notwendig werden, um z. B. von 06:00 bis 10:00 Uhr Selbstbedienungspreise, von 10:00 bis 16:00 Uhr Bedienungspreise, von 16:00 bis 20:00 Uhr wieder Selbstbedienungspreise und von 20:00 bis 06:00 Uhr Automatenbedienungspreise anzuzeigen. Da alle an der Tankstelle vorhandenen Einrichtungen, wie Zapfsäulen, Kassen, Rechner u.s.w., über solche Preisänderungsmöglichkeiten bereits verfügen, wird es notwendig, um der gesetzlich vorgeschriebenen Preisauszeichnung nachzukommen, auch die Treibstoffpreis-Anzeigevorrichtung in den automatischen Einstellungsvorgang einzubeziehen. Außerdem kann dieser Preisänderungsvorgang gebietsweise von einer zentrale aus vorgenommen werden.Especially at petrol stations, there is a need to be able to change the displayed fuel price easily. In the future, this will even be necessary several times in a day, e.g. B. from 6:00 a.m. to 10:00 a.m. self-service prices, from 10:00 a.m. to 4:00 p.m. service prices, from 4:00 p.m. to 8:00 p.m. self-service prices again and from 8:00 p.m. to 6:00 a.m. machine display prices. Since all facilities at the petrol station, such as petrol pumps, cash registers, computers, etc., already have such price change options, it is necessary to also include the fuel price display device in the automatic setting process in order to comply with the legally required price labeling. In addition, this price change process can be carried out regionally from a central location.
Aus der AT-B-388253 ist eine gattungsgemäße Vorrichtung zur Anzeige von Ankündigungen, insbesondere von Preisen in Ziffernform, vorbekannt. Für jede Ziffernstelle eines Preises ist ein Anzeigeband vorgesehen, das auf zwei parallel zueinander angeordnete Wickelwalzen jeweils teilweise aufgerollt ist und dessen zwischen den Wickelwalzen befindliche Fläche die Anzeigefläche bildet. Jede Wickelwalze ist als Hohlwalze ausgebildet und steht über eine elektromagnetische Kupplung mit einer Antriebswelle in Verbindung, welche über an deren Enden angeordnete Kettenräder und Ketten mit dem Antriebsritzel eines zentralen Antriebsmotors in Verbindungen stehen. Dabei sind für vier Zifferstellen vier in einer Ebene und parallel zueinander verlaufender Anzeigebänder mit jeweils zwei Wickelwalzen an einer Anzeigevorrichtung vorgesehen. Eine Verstellung der Ziffernanzeige eines Anzeigebandes erfolgt dadurch, daß der zentrale Antriebsmotor angetrieben und die elektromagnetische Kupplung derjenigen Wickelwalze betätigt wird, auf welche das jeweilige Anzeigeband aufgewickelt werden muß, um die Ziffernanzeige zu ändern. Um dabei zu verhindern, daß die dem auf die eine Wickelwalze aufgewickelten Anzeigeband zugeordnete weitere Wickelwalze frei mitläuft, ist jeder Wickelwalze ein Bremslager zugeordnet, so daß das Anzeigeband beim Aufwickeln auf eine Wickelwalze gespannt bleibt.AT-B-388253 is a generic device for displaying announcements, in particular prices in numerical form, previously known. A display tape is provided for each digit of a price, which is partially rolled up on two winding rollers arranged parallel to each other and whose surface between the winding rollers forms the display surface. Each winding roller is designed as a hollow roller and is connected via an electromagnetic clutch to a drive shaft which is connected to the drive pinion of a central drive motor via chain wheels and chains arranged at the ends thereof. In this case, four display tapes with four winding rollers each running on one plane and parallel to one another are provided on a display device for four digit positions. An adjustment of the numerical display of a display tape is carried out by driving the central drive motor and actuating the electromagnetic clutch of the winding roller on which the respective display tape must be wound in order to change the numerical display. In order to prevent the further winding roller associated with the display tape wound on the one winding roller from running freely, a braking bearing is assigned to each winding roller, so that the display tape remains tensioned on a winding roller during winding.
Nachteilig bei dieser bekannten Anzeigevorrichtung ist, daß jeder Wickelwalze eine elektromagnetische Kupplung und ein Bremslager zugeordnet sein müssen, daß die Wickelwalzen durchquerende Antriebswellen erforderlich sind und daß schließlich ein relativ viel Raum beanspruchender Kettentrieb notwendig ist, um das Antriebsritzel des zentralen Antriebsmotors mit allen Kettenrädern der Antriebswellen zu verbinden. Schließlich kann es trotz Verwendung der Bremslager dazu kommen, daß die notwendige Bandspannung des Anzeigebandes nicht aufrecht erhalten wird, so daß das Band lose zwischen den beiden Wickelwalzen hängt. Dies hat Nachteile in der Paßgenauigkeit der Ziffernanzeig zur Folge.Disadvantages of this known display device are that an electromagnetic clutch and a brake bearing must be assigned to each winding roller, that drive shafts traversing the winding rollers are required, and that finally a relatively large space-consuming chain drive is necessary in order to drive the drive pinion of the central drive motor with all sprockets of the drive shafts connect to. Finally, despite using the brake bearings, it can happen that the necessary tape tension of the display tape is not maintained, so that the tape hangs loosely between the two winding rollers. This has disadvantages in the accuracy of the numerical display.
Der Erfindung liegt von daher die Aufgabe zugrunde, eine Vorrichtung zur Anzeige von Ankündigungen der gattungsgemäßen Art zu schaffen, welche konstruktiv einfach aufgebaut ist und bei welcher das auf die Wickelwalzen aufgewickelte und von diesen abgewickelte Anzeigeband ständig unter konstanter Bandspannung gehalten ist.The invention is therefore based on the object to provide a device for displaying announcements of the generic type, which is structurally simple and in which the wound on the winding rollers and unwound from these display tape is constantly kept under constant belt tension.
Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1. Erfindungsgemäß ist jeder Wickelwalze ein Antriebsmotor zugeordnet, wodurch bereits der technisch-konstruktive Aufwand der Anzeigevorrichtung wesentlich verringert wird. Ferner wird der das Anzeigeband auf die eine Wickelwalze aufwickelnde Antriebsmotor mit einer höheren Drehzahl betrieben als der das Anzeigeband von der anderen Wickelwalze abwickelnde Antriebsmotor. Dadurch wird ein funktionsmäßig vorteilhafter Betriebszustand erreicht, der sich dadurch auszeichnet, daß der sich schneller drehende aufwickelnde Antriebsmotor und der sich langsamer drehende abwickelnde Antriebsmotor über das auf- bzw. abwickelnde Anzeigeband in einen Synchronlauf bei konstanter Bandspannung gezwungen werden. Durch die Verbindung der beiden von Antriebsmotoren betriebenen Wickelwalzen über das Anzeigeband werden die beiden Wickelwalzen bzw. die diesen zugeordneten Antriebsmotoren zu einer kraftschlüssig verbundenen mechanischen Einheit. Um die gewünschte konstante Bandspannung zu erhalten bzw. einen Synchronlauf der beiden Antriebsmotoren zu gewährleisten, wird der abwickelnde Antriebsmotor mit einer geringeren Drehzahl als der aufwickelnde Motor betrieben. Damit zieht der aufwickelnde Antriebsmotor über die diesem zugeordnete Wickelwalze und das Anzeigeband den abwickelnden Antriebsmotor über die diesem zugeordnete Wickelwalze mit und hält das Anzeigeband damit in einem Synchronlauf bei konstanter Bandspannung. Nach dem Erreichen der gewünschten Position werden die beiden Antriebsmotoren gleichzeitig abgeschaltet. Das Anzeigeband bleibt straff gespannt stehen, da der eventuelle Nachlauf der beiden Antriebsmotoren durch das Anzeigeband gezwungenermaßen gleich ist.The solution to this problem results from the characterizing features of claim 1. According to the invention, a drive motor is assigned to each winding roller, whereby the technical and constructive outlay of the display device is significantly reduced. Furthermore, the drive motor winding the display tape onto the one winding roller is operated at a higher speed than the drive motor unwinding the display tape from the other winding roller. As a result, a functionally advantageous operating state is achieved, which is characterized in that the faster rotating winding drive motor and the slower rotating unwinding drive motor are forced into a synchronous operation at constant belt tension via the winding or unwinding display tape. By connecting the two winding rollers operated by drive motors via the display tape, the two winding rollers or the drive motors assigned to them become a non-positively connected mechanical unit. To get the desired constant belt tension or one To ensure synchronous running of the two drive motors, the unwinding drive motor is operated at a lower speed than the winding motor. The winding drive motor thus pulls the unwinding drive motor over the winding roller assigned to it via the winding roller assigned to it and the display tape and thus keeps the display tape in synchronous operation with constant belt tension. After reaching the desired position, the two drive motors are switched off simultaneously. The display band remains taut because the possible overrun of the two drive motors by the display band is necessarily the same.
In der bevorzugten Ausführungsform sind die Antriebsmotoren als Elektromotoren ausgebildet, deren Spannung zur Bewirkung der gewünschten unterschiedlichen Antriebsdrehzahlen geregelt wird. Dabei ist die Spannung des das Anzeigeband auf eine Wickelwalze aufwickelnden Elektromotors die Speisespannung des Betriebsnetzes und die Spannung des das Anzeigeband von der anderen Wickelwalze abwickelnden Elektromotors geringer als die Speisespannung des Betriebsnetzes. In der ganz besonders bevorzugten Ausführungsform sind die beiden Elektromotoren parallel geschaltete Gleichstrommotoren, insbesondere Getriebemotoren, zu denen jeweils Widerstände in Reihe und zu diesen parallel geschaltete Dioden mit entgegengesetzt gerichteter Sperrichtung vorgeschaltet sind. Durch einfache Umpolung der Speisespannung der beiden Gleichstrommotoren kann jeweils die eine oder die andere Wickelwalze als aufwickelnde und die andere als abwickelnde Wickelwalze geschaltet werden. Die Verwendung von Getriebemotoren mit hoher Übersetzung verhindert einen Rücklauf der Wickelwalzen, wodurch eine konstante Bandspannung im Stillstand erreicht wird. Die Elektromotoren sind insbesondere als in die Wickelwalzen eingebaute Getriebemotoren ausgebildet.In the preferred embodiment, the drive motors are designed as electric motors, the voltage of which is regulated to effect the desired different drive speeds. The voltage of the electric motor winding the display tape onto a winding roller is the supply voltage of the operating network and the voltage of the electric motor unwinding the display tape from the other winding roller is lower than the supply voltage of the operating network. In the very particularly preferred embodiment, the two electric motors are DC motors connected in parallel, in particular geared motors, to each of which resistors are connected in series and diodes connected in parallel to them with an opposite blocking direction. By simply reversing the polarity of the supply voltage of the two DC motors, one or the other winding roller can be switched as a winding roller and the other as a winding winding roller. The use of geared motors with high gear ratios prevents a return of the winding rollers, whereby a constant sliver tension is achieved at a standstill. The electric motors are designed in particular as geared motors built into the winding rollers.

Die Fig. 1 zeigt eine Vorrichtung zur Anzeige von Ankündigungen in Form einer Kraftstoffpreisanzeige in Ziffernform. Die Vorrichtung umfaßt ein kastenförmiges Gehäuse 1, in dem auf der Vorderseite und auf der nicht dargestellten Rückseite je zwei Gruppen aus je drei Wickeleinheiten 2 gelagert sind, die jeweils aus einer oberen Wickelwalze 3 und einer im Abstand zu dieser angeordneten unteren Wickelwalze 4 gebildet sind, auf welche ein Anzeigeband 5, insbesondere Kunststoffband aus lichtdurchlässigem oder klarsichtigem Material, mit seinen beiden Enden aufgewickelt ist bzw. auf- und abgewickelt wird. Oberhalb einer jeden Gruppe von Wickeleinheiten 2 befinden sich Anzeigeflächen 6 für Produktebezeichnungen, wie "Diesel" und "Super". Die auf den einzelnen Anzeigebändern befindlichen Symbole, insbesondere Ziffern, sind nicht dargestellt.1 shows a device for displaying announcements in the form of a fuel price display in numerical form. The device comprises a box-shaped housing 1, in which two groups of three
Die Fig. 2 zeigt die Anordnung je einer Ebene von Wickeleinheiten 2 auf Vorder- und Rückseite der Anzeigevorrichtung. Die Fig. 3 zeigt in vergrößerten Darstellung den genauen Aufbau und die genaue Anordnung der Wickelwalzen 3,3' im Gehäuse 1. Das Gehäuse 1 umfaßt dabei zwischen jeder Wickeleinheit 2 bzw. zwischen zwei in einer Achse hintereinander angeordneten Wickelwalzen 3, 3' je ein Seitenblech 10, auf welches für jede Wickelwalze 3,3' ein Lagerring 12 unter Zwischenlage je einer Bronzefederscheibe 13, die auch dem Schutz des Zuleitungskabels zum Motor 8 dient, angeflanscht ist. Das Anflanschen erfolgt durch Schraubverbindungselemente 11. Die Umfangsflächen der Lagerringe 12 sind kreisförmig ausgebildet und konzentrisch zur Achse angeordnet und führen die rohrförmig ausgebildeten Wickelwalzen 3,3', die am stirnseitigen Ende mit Flanschen 14 versehen sind, welche eine seitliche Begrenzung für das jeweils aufgewickelte Anzeigeband 5 bilden. Innerhalb einer jeden Wickelwalze 3,3' ist ein Getriebemotor 8 mittels eines Motorbleches 9 und mehrerer Stehbolzen 15 auf einen Lagerring 12 aufgeflanscht, so daß der Getriebemotor 8 von den Seitenblechen 10 des Gehäuses 1 getragen ist. Auf den Antriebszapfen 16 des Getriebemotors 8 ist eine Mitnehmerscheibe 17 drehfest aufgesetzt, welche mit ihrer Mantelfläche genau den Innendurchmesser der rohrförmigen Wickelwalze 3,3' ausfüllt. Über Stiftschrauben 18 ist die Mitnehmerscheibe 17 formschlüssig mit der rohrförmigen Wickelwalze 3,3' verbunden. Beim Betrieb eines Getriebemotors 8 wird somit über die Mitnehmerscheibe 17 die zugehörige rohrförmige Wickelwalze 3,3' angetrieben, welche auf den Umfangsflächen zweier Lagerringe 12 drehbar ist und an den Seitenblechen 10 über die Bronzefederscheiben 13 geführt ist. Zur Verbindung der einzelnen Seitenbleche 10 sind in horizontoler Richtung gemäß den Fig. 2 und 3 Spannstangen 19 und Distanzrohre 20 und in vertikaler Richtung variable Verbindungsstreben 21 vorgesehen, die in den Fig. 1, 4 und 5 ersichtlich sind.2 shows the arrangement of one level of
In der Fig. 5 ist die Führung eines Anzeigebandes 5 einer Wickeleinheit 2 zwischen oberer Wickelwalze 3 und unterer Wickelwalze 4 dargestellt. Hierzu tragen beide Seitenbleche 10 in einem Abstand zu den Achsen der beiden Wickelwalzen 3,3' Umlenkwalzen 22 mit seitlichen Führungsbuchsen 23, um welche herum das Anzeigeband 5 geführt und zwischen denen das Anzeigeband 5 frei sichtbar ist. Die jeweils von der oberen Seite der Wickelwalzen 3,4 abgezogenen Anzeigebänder 5 sind mit seitlichen Lochungen 24 versehen, die im Bereich einer in Fig. 5 am unteren Seitenblech 10 dargestellten Bandabtastung 25 umlaufen und wodurch die exakte Positionierung des Anzeigebandes 5 und damit des auf diesem befindlichen Zeichens eingestellt wird. Die Anzeigebänder 5 aus Kunststoff verlaufen in nicht näher dargestellter Weise hinter im Gehäuse 1 gehaltenen Plexiglasabdeckungen und werden von der Innenseite her über zwischen den vorder- und rückseitigen Wickeleinheiten 2 angebrachte TL-Röhren 26 beleuchtet.5, the guidance of an
In der in den Fig. 1 bis 5 dargestellten Ausführungsform sind die Anzeigebänder 5 der vorder- und rückseitigen Wickeleinheiten 2 jeweils hinter der vorderen bzw. rückwärtigen Plexiglasabdeckung geführt. Die oberen und unteren Wickelwalzen 3,4 der vorderen und hinteren Wickeleinheiten 2 befinden sich dabei mit ihren Achsen jeweils auf einer gemeinsamen horizontalen Ebene.In the embodiment shown in FIGS. 1 to 5, the
In der Ausführungsform nach Fig. 6 sind die Achsen der oberen und unteren Wickelwalzen 3,4;3'',4'' vertikal zueinander versetzt und das Anzeigeband 5, der rückwärtigen, in größerem Achsabstand versehenen Wickeleinheit 2' ist nach vorne geführt und verläuft parallel zu und in geringem Abstand vor dem Anzeigeband 5 der vorderen Wickeleinheit 2. Für das Wickelband 5' sind somit zusätzliche Umlenkwalzen 22' erforderlich. Bei dieser Ausführungsform der Anzeigevorrichtung ist das vordere Anzeigeband 5' der rückwärtigen Wickeleinheit 2' ganz oder teilweise durchsichtig, damit durch das vordere Anzeigeband 5' hindurch die auf dem hinteren Anzeigeband 5 der vorderen Wickeleinheit 2 befindlichen Symbole sichtbar werden können.In the embodiment according to FIG. 6, the axes of the upper and lower winding
In der Fig. 7 ist die Schaltungsanordnung der beiden Getriebemotoren 8,8' einer jeden Wickeleinheit 2 dargestellt. Die Getriebemotoren 8,8' sind Gleichstrommotoren, zu denen jeweils Widerstände 27,27' in Reihe und zu diesen parallel geschaltete Dioden 28,28' mit entgegengesetzt gerichteter Sperrichtung geschaltet sind. Bei Anlage der positiven Spannung am oberen Anschlußpunkt 29 ist die Diode 28 des Getriebemotors 8 leitend, wohingegen die Diode 28' des Getriebemotors 8' sperrt. Damit wird der Getriebemotor 8 mit der an die Anschlußpunkte 29,30 angelegten Speisespannung des Betriebsnetzes betrieben. Der Getriebemotor 8' dagegen wird nur mit der über den Widerstand 27' geführten Speisespannung des Betriebsnetzes betrieben, d. h. mit einer geringeren Spannung, so daß die Antriebsdrehzahl des Getriebemotors 8' geringer ist als die Antriebsdrehzahl des Getriebemotors 8. Der Getriebemotor 8, der z. B. in der oberen Wickelwalze 3 einer Wickeleinheit 2 angeordnet ist, wickelt das zugehörige Anzeigeband 5 auf, wohingegen der dann in der unteren Wickelwalze 4 der gleichen Wickeleinheit 2 angeordnete Getriebemotor 8' das Anzeigeband 5 mit geringerer Drehzahl abwickelt, so daß das Anzeigeband 5 ständig unter einer Zugspannung gehalten ist. Die beiden Getriebemotoren 8,8' werden in gegenläufiger Drehrich-tung betrieben.
