Description

Betätigungseinrichtung für Antriebselemente einer PersonenförderanlageActuating device for drive elements of a passenger conveyor system
Die Erfindung betrifft eine Einrichtung zur Betätigung von Antriebselementen einer Personenförderanlage, insbesondere einer Rolltreppe oder eines Rollsteiges.The invention relates to a device for actuating drive elements of a passenger conveyor system, in particular an escalator or an escalator.
Allgemein bekannt ist bei einer Rolltreppe oder einem Rollsteig den Einschaltvorgang des Antriebsmotors dadurch herbeizuführen daß ein Sensor, der im Bereich der Fußbodenabdeckung vorgesehen ist, auf Druck anspricht und über eine Relaissteuerung den Antriebsmotor startet, sobald die Fußbodenabdeckung belastet wird. Selbige wird hierbei um einen bestimmten Weg nach unten geführt, was vielfach unangenehme Geräusche mit sich bringt und auch für den jeweiligen Benutzer der Rolltreppe bzw. des Rollsteiges zu ungewollten Problemen bezüglich des Absenkens der Fußbodenabdeckung führt.In an escalator or a moving walkway, it is generally known to bring about the switching-on of the drive motor in that a sensor, which is provided in the area of the floor cover, responds to pressure and starts the drive motor via a relay control as soon as the floor cover is loaded. The same is led down a certain way, which often brings with it unpleasant noises and also leads to unwanted problems with regard to the lowering of the floor covering for the respective user of the escalator or the escalator.
Außerhalb der Personenförderanlage vorgesehene akustisch oder optisch reagierende Systeme zur Betätigung der jeweiligen Antriebselemente sind - weil leicht zugänglich - vor Vandalismus nicht gefeit.Acoustically or optically reacting systems for actuating the respective drive elements provided outside the passenger conveyor system are - because they are easily accessible - not immune to vandalism.
Ziel des Erfindungsgegenstandes ist es eine Einrichtung zur Betätigung von Antriebselementen einer Personenförderanlage dergestalt zu konzipieren, daß einerseits Vandalismus ausgeschlossen und andererseits die unerwünschte Absenkung von Fußbodenbereichen auf ein absolutes Minimum beschränkt werden kannThe aim of the subject matter of the invention is to design a device for actuating drive elements of a passenger conveyor system in such a way that on the one hand vandalism is excluded and on the other hand the undesired lowering of floor areas can be kept to an absolute minimum
Dieses Ziel wird erreicht mit einer Einrichtung zum Betätigen von Antriebselementen einer Personenförderanlage, insbesondere einer Rolltreppe oder eines Rollsteiges, indem im Bereich des Ein- und / oder Ausganges der Personenförderanlage mindestens ein mit mindestens einer Auswerteelektronik in Wirkverbindung stehender verdeckt angeordneter auf Druck reagierender Lichtwellenleiter angeordnet ist.This goal is achieved with a device for actuating drive elements of a passenger conveyor system, in particular an escalator or a moving walkway, in that at least one concealed pressure-sensitive optical waveguide which is operatively connected to at least one evaluation electronics is arranged in the area of the entrance and / or exit of the passenger conveyor system .
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den zugehörigen Unteransprüchen zu entnehmen. Vorgeschlagen wird auch die Verwendung eines aus mindestens einem Lichtwellenleiter gebildeten, insbesondere innerhalb einer Umhüllung angeordneten Kontaktelementes in Wirkverbindung mit mindestens einer Auswerteelektronik als Schaltelement mindestens eines Antriebes einer Personenförderanlage, insbesondere einer Rolltreppe oder eines Rollsteiges.Advantageous developments of the subject matter of the invention can be found in the associated subclaims. It is also proposed to use a contact element formed from at least one optical waveguide, in particular arranged within an envelope, in operative connection with at least one evaluation electronics as switching element of at least one drive of a passenger conveyor system, in particular an escalator or an escalator.
Der Lichtwellenleiter, respektive die Umhüllung, ist hierbei vorzugsweise im Fußbodenbereich, insbesondere im Bereich der Grubenabdeckung der Rolltreppe bzw. des Rollsteiges, angeordnet.The optical waveguide, or the covering, is preferably arranged in the floor area, in particular in the area of the pit cover of the escalator or moving walk.
Der insbesondere von einer Umhüllung umgebene Lichtwellenleiter kann - je nach Anwendungsfall - unterschiedlichste Konturen aufweisen. So kann der Lichtwellenleiter beispielsweise innerhalb eines Streifens geradlinig verlaufend vorgesehen werden, oder aber bei Verwendung als Flächenelement darin etwa mäanderförmig verlaufend angeordnet werden.The optical waveguide, in particular surrounded by a sheath, can have a wide variety of contours, depending on the application. For example, the optical waveguide can be provided in a straight line within a strip, or, when used as a surface element, can be arranged in an approximately meandering manner therein.
Bei einer Rolltreppe oder einem Rollsteig kann es ausreichend sein, den Lichtwellenleiter, respektive die Umhüllung streifenartig auszubilden und ausschließlich im Bereich des Rahmens der Grubenabdeckung vorzusehen.In the case of an escalator or a moving walkway, it may be sufficient to form the optical waveguide or the covering in the form of a strip and to provide it only in the area of the frame of the pit cover.
Ebenfalls denkbar ist die Anwendung des Lichtwellenleiters als Auslöseelement zur Anforderung eines Aufzuges und zum Öffnen der Aufzugstür.It is also conceivable to use the optical waveguide as a trigger element for requesting an elevator and for opening the elevator door.
Der besondere Anwendungsfall wird jedoch darin gesehen, den Antriebsmotor einer Rolltreppe bzw. eines Rollsteiges zu starten oder stillzusetzen, indem ein auf den Lichtwellenleiter oder die ihn umgebende Umhüllung ausgeübter Druck infolge Veränderung der Lichtwellenausbreitung die nachgeschaltete Auswerteelektronik veranlaßt, den entsprechenden Kontakt zum Anfahren oder Stillsetzen des Antriebsmotors auszulösen.The special application is seen, however, in starting or stopping the drive motor of an escalator or moving walkway, as a result of a pressure exerted on the optical waveguide or the envelope surrounding it, as a result of changes in the lightwave propagation, causing the downstream evaluation electronics, the corresponding contact for starting or stopping the Trigger drive motor.
Der Lichtwellenleiter, insbesondere die ihn umgebende Hülle, dient somit als auf Druck reagierender Sensor, wobei als Ansprechkriterium für die Auswerteelektronik die Veränderung des optischen Übertragungsverhaltens des jeweiligen Lichtweilenleiters anzusehen ist. Die Auswerteelektronik kann hierbei auf unterschiedlichste Grundlasten vorprogrammiert, d. h. kalibriert werden. Dies unter Berücksichtigung des Umstandes, daß der Lichtwellenleiter, bzw. die ihn umgebende streifen- oder flächenartig ausgebildete Hülle unterhalb von Materialien unterschiedlichsten Gewichtes angeordnet werden kann.The optical waveguide, in particular the sheath surrounding it, thus serves as a sensor reacting to pressure, the change in the optical transmission behavior of the respective optical fiber being regarded as the response criterion for the evaluation electronics. The evaluation electronics can be preprogrammed, ie calibrated, for a wide variety of basic loads. This takes into account the fact that the optical waveguide, or the surrounding strip-shaped or sheet-like casing can be arranged below materials of different weights.
So kann es beispielsweise geschehen, daß - bei Verwendung des erfindungsgemäßen Lichtwellenleiters, ggf. in Verbindung mit der ihn umgebenden Hülle, - im Ein- und / oder Ausgangsbereich eines Aufzuges z. B. Marmorplatten Estrich oder lediglich ein PVC- Belag vorgesehen ist. Diese Materialien bedingen andersartige Kalibrierungszustände der Auswerteeiektronik im Hinblick auf die Voreinstellung einer definierten Grundlast, wobei noch gewisse Toleranzen zu berücksichtigen sind, damit das Antriebselement nicht bei geringsten Druckschwankungen bereits in anfahrender bzw. stillsetzender Weise betätigt wird.So it can happen, for example, that - when using the optical waveguide according to the invention, possibly in conjunction with the envelope surrounding it - in the entrance and / or exit area of an elevator, for. B. marble slabs screed or only a PVC covering is provided. These materials require different calibration states of the evaluation electronics with regard to the presetting of a defined base load, certain tolerances still having to be taken into account so that the drive element is not actuated in the starting or stopping manner with the slightest pressure fluctuations.
Die Anwendungsgebiete des Erfindungsgegenstandes sind vielfältigster Art; gleiches gilt für die Ausbildung der Hülle bzw. die räumliche Führung des bzw. der Lichtwellenleiter innerhalb derselben.The areas of application of the subject matter of the invention are very diverse; the same applies to the formation of the sheath or the spatial guidance of the optical waveguide (s) within it.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:The subject matter of the invention is illustrated in the drawing using an exemplary embodiment and is described as follows. Show it:

Figur 1 zeigt als Prinzipskizze den Eingangsbereich 1 eines Rollsteiges 2, wobei im wesentlichen folgende Bauteile erkennbar sind:FIG. 1 shows a schematic diagram of the entrance area 1 of a moving walkway 2, the following components being essentially recognizable:
eine in dieser Skizze offen dargestellte Grube 3, innerhalb derer ein Antriebsmotor 4 angeordnet ist, der über nicht weiter dargestellte Getriebeelemente einerseits die Paletten 5 und andererseits die Handläufe 6 des Rollsteiges 2 antreibt (Pfeil- richtung). Die Grube 3 wird von einem lediglich angedeuteten Rahmen 7 begrenzt, auf welchen eine in dieser Figur nicht dargestellte Grubenabdeckung auflegbar und dort festlegbar ist.a pit 3 shown openly in this sketch, within which a drive motor 4 is arranged, which on the one hand drives the pallets 5 and, on the other hand, the handrails 6 of the moving walk 2 via gear elements (not shown) direction). The pit 3 is delimited by a frame 7, only indicated, on which a pit cover (not shown in this figure) can be placed and fixed there.
Auf dem Rahmen 7 wird ein von einer Hülle (nicht dargestellt) umgebener Lichtwellenleiter 8, in Form eines Streifens aufgebracht, bei Bedarf geklebt, so daß der Lichtwellenleiter sich im Betriebszustand des Rollsteiges 2 zwischen dem Rahmen 7 und der nicht weiter dargestellten Grubenabdeckung befindet. Je nach Anwendungsfall kann es sinnvoll sein anstelle von Tageslicht eine separate Lichtquelle 9 zu verwenden, um den Lichtwellenleiter 8 mit Licht zu versorgen. Der Lichtwellenleiter wirkt an seinem Ausgang 10 über eine Signalleitung 11 mit einer Auswerteelektronik 12 zusammen, die bei Bedarf Bestandteil einer übergeordneten Zentralsteuerung sein kann. Die Auswerteelektronik ist mikroprozessorgesteuert und steht über eine weitere Leitung 13 mit dem Antriebsmotor 4 in Verbindung.On the frame 7 is surrounded by an envelope (not shown) optical fiber 8, applied in the form of a strip, glued if necessary, so that the optical fiber is in the operating state of the moving walk 2 between the frame 7 and the pit cover, not shown. Depending on the application, it may be useful to use a separate light source 9 instead of daylight in order to supply the optical waveguide 8 with light. At its output 10, the optical waveguide interacts with evaluation electronics 12 via a signal line 11, which can be part of a higher-level central control if required. The evaluation electronics is microprocessor-controlled and is connected to the drive motor 4 via a further line 13.
Durch die nicht dargestellte Grubenabdeckung wird auf den Lichtwellenleiter 8 eine Druckkraft ausgeübt, die als sogenannte Grundlast in der Auswerteelektronik 12 abgespeichert wird. Dieser Grundlast wird nun eine Toleranzlast überlagert, so daß nicht bei geringsten Belastungen der Grubenabdeckung mit einem Starten des Antriebsmotors 4 gerechnet werden muß. Erst bei tatsächlichem Personenbetrieb wird über die dann auf die Grubenabdeckung eine Druckkraft ausgeübt, durch die eine derartige Verformung des Lichtwellenleiters 8 bzw. die ihn umgebende Hülle ausgeübt, daß infolge der veränderten optischen Übertragungsverhaltens die Auswerteelektronik anspricht und über die Leitung 13 den Antriebsmotor 4 startet. Technisch realisierbar ist ebenfalls, den Antriebsmotor über einen Frequenzumrichter (nicht dargestellt) anzusteuern, dergestalt, daß die Paletten 5 und die Handläufe 6 sich im Modus eines Schleichganges befinden, so daß über die Auswerteelektronik 12 der Schleichgang beendet und die Fahrgeschwindigkeit erzeugt werden kann.The pit cover, not shown, exerts a compressive force on the optical waveguide 8, which is stored as a so-called base load in the evaluation electronics 12. A tolerance load is now superimposed on this base load, so that the drive motor 4 does not have to be started at the slightest loads on the pit cover. Only when people are actually operating is a compressive force exerted on the pit cover, by which such a deformation of the optical waveguide 8 or the sheath surrounding it is exerted that the evaluation electronics respond due to the changed optical transmission behavior and the drive motor 4 starts via the line 13. It is also technically feasible to control the drive motor via a frequency converter (not shown) in such a way that the pallets 5 and the handrails 6 are in the crawl mode, so that the crawl speed can be ended via the evaluation electronics 12 and the driving speed can be generated.
Im nicht dargestellten Ausgangsbereich des Rollsteiges 2 kann der Vorgang des Startens des Antriebsmotors bei Bedarf in umgekehrter Weise ablaufen, indem dann das Drucksignal, das auf die Grubenabdeckung einwirkt Kriterium zum Still- setzen des Antriebsmotors ist. Im täglichen Betrieb des Rollsteiges spielt das Stillsetzen des Antriebsmotors jedoch nicht so eine große Rolle, da eine Vielzahl von Personen den Rollsteig benutzen, so daß weitere Kriterien berücksichtigt werden müssen, um einen sinnvollen Betrieb des Rollsteiges bezüglich des Schaltverhaltens des Antriebsmotors zu realisieren. Dies kann im Einzelfall dadurch realisiert werden, daß lastabhängig über ein Zeitglied der Antriebsmotor stillgesetzt wird. Dieser Vorgang ist der jeweils zum Einsatz gelangenden Anlage in entsprechender Weise anzupassen.In the exit area of the moving walkway 2, which is not shown, the process of starting the drive motor can, if necessary, take place in a reversed manner, in that the pressure signal acting on the pit cover then acts as a criterion for stopping. drive motor. Stopping the drive motor does not play such a major role in the daily operation of the moving walk, since a large number of people use the moving walk, so that further criteria must be taken into account in order to implement sensible operation of the moving walk with regard to the switching behavior of the drive motor. In individual cases, this can be achieved in that the drive motor is stopped depending on the load via a timer. This process must be adapted accordingly to the system used.
Figur 2 zeigt als Teilansicht die Grube 3 samt Rahmen 7. Erkennbar sind der Antriebsmotor 4 sowie die Signalleitung 10 und die Steuerleitung 13 sowie der Lichtwellenleiter 8, der in diesem Beispiel mäanderförmig auf dem Rahmen 7 verläuft, um auf diese Art und Weise eine vergrößerte Druckfläche zu erzeugen. Der Lichtwellenleiter 8 ist von einer Hülle 14 umgeben, so daß einen Streifen gebildet wird.Figure 2 shows a partial view of the pit 3 together with the frame 7. The drive motor 4 as well as the signal line 10 and the control line 13 as well as the optical waveguide 8 can be seen, which in this example runs in a meandering manner on the frame 7 in order to enlarge the printing area in this way to create. The optical fiber 8 is surrounded by a sheath 14 so that a strip is formed.
Figur 3 zeigt einen Schnitt gem. Linie A - A der Figur 2, wobei hier jedoch auch die Grubenabdeckung 15, die sogenannte Fußbodenabdeckung, dargestellt ist. Erkennbar ist der Rahmen 7, der Lichtwellenleiter 8, die Lichtquelle 9, die Auswerteelektronik 12 sowie der Antriebsmotor 4. Der Lichtwellenleiter 8 ist innerhalb der Hülle 14 eingebracht, die anwendungsbedingt aus unterschiedlichsten Materialien, hier aus Kunststoff, bestehen kann. Die Hülle 14 kann durch Kleben auf der Rahmenoberfläche 16 fixiert sein, andere Befestigungs- bzw. Führungsmöglichkeiten sind jedoch ebenfalls denkbar. Über die Lichtquelle 9 wird mit einem vorgebbaren optischen Verhalten in den Lichtwellenleiter 8 eingespeist und dieses Signal der Auswerteelektronik 12 zur Verfügung gestellt. Das auf der Hülle 14, bzw. dem Lichtwellenleiter 8 ruhende Gewicht der Grubenabdeckung 15 wird als Grundlast in der Auswerteelektronik 12 abgespeichert, wobei eine weitere Toleranzschwelle vorgesehen ist, die ein ungewolltes Starten des Antriebsmotors 4 verhindert. Erst bei Überschreiten diese Toleranzwertes, z. B. sobald eine Person die Grubenabdeckung 14 betritt, wird ein derartiger Druck p auf dieselbe ausgeübt, daß die optischen Eigenschaften des als Glasfaser ausgebildeten Lichtwellenleiters 8 verändert werden. Dies wiederum bewirkt eine Signaländerung, die die Auswerteelek- tronik 12 erfaßt und den Antriebsmotor 4 startet bzw. aus einem ev. Schleichgang auf volle Antriebsleistung bringt. Figure 3 shows a section acc. Line A - A of Figure 2, but here also the pit cover 15, the so-called floor cover, is shown. The frame 7, the optical waveguide 8, the light source 9, the evaluation electronics 12 and the drive motor 4 can be seen. The optical waveguide 8 is introduced inside the casing 14, which can be made of different materials, here plastic, depending on the application. The sleeve 14 can be fixed to the frame surface 16 by gluing, but other fastening or guiding options are also conceivable. Via the light source 9, a predefinable optical behavior is fed into the optical waveguide 8 and this signal is made available to the evaluation electronics 12. The weight of the pit cover 15 resting on the sheath 14 or the optical waveguide 8 is stored as a basic load in the evaluation electronics 12, a further tolerance threshold being provided which prevents the drive motor 4 from starting unintentionally. Only when this tolerance value is exceeded, e.g. B. as soon as a person enters the pit cover 14, such a pressure p is exerted thereon that the optical properties of the optical waveguide 8 designed as an optical fiber are changed. This in turn causes a signal change that the evaluation elec- tronic 12 detected and the drive motor 4 starts or brings from a possible creep speed to full drive power.
