Description

Die Erfindung betrifft eine Einrichtung zur Betätigung von Antriebselementen einer Personenförderanlage, insbesondere einer Rolltreppe oder eines Rollsteiges, gem. gattungsgemäßem Teil des ersten Patentanspruches.The invention relates to a device for actuating drive elements of a Passenger conveyor system, in particular an escalator or a moving walkway, gem. generic part of the first claim.

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.The switching-on process is generally known in the case of an escalator or a moving walkway of the drive motor by causing a sensor in the area the floor cover is provided, responsive to pressure and via a relay control the drive motor starts as soon as the floor cover loads becomes. The same is led here by a certain way down, which many unpleasant noises and also for the respective user the escalator or the moving walkway to unwanted problems Lowering the floor cover leads.

Außerhalb der Personenförderanlage vorgesehene akustisch oder optisch reagierende Systeme zur Betätigung der jeweiligen Antriebselemente sind - weil leicht zugänglich - vor Vandalismus nicht gefeit.Provided outside the passenger conveyor acoustically or optically responsive Systems for actuating the respective drive elements are - because easy accessible - not immune to vandalism.

Durch die FR-A 2672681 ist eine gattungsgemäße Einrichtung zum Betätigen von Antriebselementen, u.a. einer Personenförderanlage, zu entnehmen. Innerhalb einer im Bereich des Ein-/Ausganges der Personenförderanlage vorgesehenen ganzflächig dort vorgesehener Matte ist ein Lichtwellenleiter, bedarfsweise mäanderförmig geführt, angeordnet, der bei einem bestimmten Druck reagiert, dergestalt, daß der Gefahrenbereich abgeschaltet wird. Eine derartige Anordnung bringt eine Vielzahl von Quadratmetern an einzusetzendem Grundmaterial (Umhüllung) mit sich, innerhalb selbiger der Lichtwellenleiter eingebracht werden muß. Infolge der flächigen Anordnung der Umhüllung bedarf es zusätzlicher Auflageelemente, damit die Umhüllung nicht durchhängt und Meßergebnisse verfälscht werden.By FR-A 2672681 a generic device for actuating Drive elements, u.a. a passenger conveyor system, remove. Within one provided in the area of the input / output of the passenger transport system Over the whole area provided there mat is an optical waveguide, if necessary, meandering guided, which reacts at a certain pressure, in such a way, that the danger area is switched off. Such an arrangement brings a large number of square meters of base material to be used (wrapping) with itself, within the same fiber optic cable must be introduced. As a result the planar arrangement of the envelope requires additional support elements, so that the wrapper does not sag and measurement results are distorted.

Ziel des Erfindungsgegenstandes ist es eine im gattungsbildenden Teil des ersten Patentanspruches beschriebene Einrichtung dergestalt weiterzubilden, daß unerwünschte Absenkungen von Fußbodenbereichen auf ein absolutes Minimum beschränkt werden und der Materialverbrauch reduziert wird, ohne daß Meßergebnisse verfälscht werden.The object of the subject invention is one in the generic part of the first Further develop device described in such a way that unwanted Reductions of floor areas are kept to an absolute minimum and the material consumption is reduced without measuring results be falsified.

Dieses Ziel wird mit den im kennzeichnenden Teil des ersten Patentanspruches aufgeführten Merkmalen erreicht.This object is achieved with the in the characterizing part of the first claim achieved characteristics.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den zugehörigen Unteransprüchen zu entnehmen.Advantageous developments of the subject invention are the associated Subclaims refer.

Der Lichtwellenleiter, respektive die Umhüllung, ist im Fußbodenbereich, insbesondere im Bereich der Grubenabdeckung der Rolltreppe bzw. des Rollsteiges, angeordnet.The optical waveguide, or the cladding, is in the floor area, in particular in the area of the pit cover of the escalator or moving walkway, arranged.

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 particular surrounded by a clad optical fiber can - depending on Application - have a wide variety of contours. So can the optical fiber For example, provided within a strip extending straight be, or when used as a surface element therein meandering approximately be arranged running.

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.For an escalator or a moving walkway, it may be sufficient to use the optical fiber, respectively wrapping the wrapping strip-like and exclusively in the area of the pit cover frame.

Ebenfalls denkbar ist die Anwendung des Lichtwellenleiters als Auslöseelement zur Anforderung eines Aufzuges und zum Öffnen der Aufzugstür.Also conceivable is the use of the optical waveguide as a triggering element to request a lift and to open 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 Uchtwellenleiter 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. However, the particular application is seen in the drive motor an escalator or a moving walk to start or shut down. by putting one on the Uchtwellenleiter or the surrounding surrounding pressure exerted pressure due Change of the light wave propagation the downstream evaluation electronics causes the corresponding contact to start or stop the drive motor trigger.

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 Lichtwellenleiters anzusehen ist. The optical waveguide, in particular the surrounding casing, thus serves as on Pressure-responsive sensor, being used as a response criterion for the evaluation the change in the optical transmission behavior of the respective optical waveguide is to be considered.

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 evaluation electronics can be pre-programmed for a wide variety of basic loads, d. H. be calibrated. This taking into account the circumstance that the optical waveguide, or the strip or area surrounding it Case arranged below materials of different weight can be.

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 Kalibrienrngszustände der Auswerteelektronik 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 inventive Optical waveguide, possibly in conjunction with the surrounding sheath, - im Input and / or output area of a lift z. B. marble slab screed or only a PVC coating is provided. These materials require different types Kalibrierrngszustände the transmitter with regard to the default a defined base load, whereby certain tolerances still have to be considered are, so that the drive element not at the slightest pressure fluctuations already is operated in an approaching or stopping manner.

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 fields of application of the subject invention are diverse in nature; same applies to the formation of the shell or the spatial leadership of the or Optical fiber within the same.

Figur 1 zeigt als Prinzipskizze den Eingangsbereich 1 eines Rollsteiges 2, wobei im wesentlichen folgende Bauteile erkennbar sind:

  • 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 (Pfeilrichtung). 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.
    • 1 shows a schematic diagram of the entrance area 1 of a moving walkway 2, wherein essentially the following components are recognizable:
  • a pit 3 shown open in this sketch, within which a drive motor 4 is arranged, which drives the pallets 5 on the one hand and the handrails 6 of the moving walk 2 via the transmission elements (not shown) on the one hand (arrow direction). The pit 3 is bounded by a merely indicated frame 7, 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 Lichtwellen-Jeiter 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 a shell (not shown) optical waveguide 8, applied in the form of a strip, glued if necessary, so that the Optical fiber in the operating state of the moving walkway 2 between the frame 7 and not shown pit cover is located. Depending on the application It may be useful instead of daylight a separate light source 9 to use to supply the optical waveguide 8 with light. The light wave jade acts at its output 10 via a signal line 11 with an evaluation 12 together, which if needed part of a higher-level central control can be. The transmitter is microprocessor-controlled and is connected via a further line 13 to the drive motor 4 in connection.

    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.By not shown pit cover is on the optical waveguide 8 a Compressive force exerted as a so-called base load in the transmitter 12 is stored. This base load is now superimposed on a tolerance load, so that not at minimum loads of the pit cover with a start the drive motor 4 must be expected. Only with actual person operation is applied via the then on the pit cover a compressive force, by the such a deformation of the optical waveguide 8 and the surrounding him Case exerted that due to the changed optical transmission behavior the transmitter responds and via line 13 the drive motor 4 starts. Technically feasible is also the drive motor via a Frequency converter (not shown) to control, such that the pallets. 5 and the handrails 6 are in the creep mode so that over the transmitter 12 crawl the gear and the 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 Stillsetzen 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 output region of the moving walkway 2, not shown, the process of Start the drive motor in reverse, if necessary, by then the pressure signal acting on the pit cover. Criterion for stopping of the drive motor is. In the daily operation of the moving walkway, the shutdown plays However, the drive motor is not such a big role, as a variety of People use the platform, so that further criteria are taken into account need to ensure meaningful operation of the moving walkway in terms of switching behavior to realize the drive motor. This can be realized in individual cases be that load-dependent via a timer, the drive motor is stopped. This process is the particular used in the corresponding installation in the corresponding Way to adapt.

    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.FIG. 2 shows a partial view of the pit 3 together with the frame 7. The drive motor can be seen 4 and the signal line 10 and the control line 13 and the optical waveguide 8, which in this example meanders on the frame 7, to produce in this way an enlarged printing surface. The optical fiber 8 is surrounded by a sheath 14, so that a strip is formed.

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 Auswerteelektronik 12 erfaßt und den Antriebsmotor 4 startet bzw. aus einem ev.
