Definitions
- the present invention relates to a passenger transport device according to the preamble of patent claim 1.
- Conveying devices for transporting people, in particular escalators, moving walks or conveyor belts, in various designs are known from the prior art.
- Such devices are used for example for transporting people between levels of a building (escalators) or along a level path (moving walks).
- an escalator includes a plurality of steps or a belt on which people to be conveyed are to be carried from one location to another.
- a handrail is usually provided, which runs over a balustrade and provides a surface on which carried people can hold for example.
- Such a handrail typically has two handrail bands each having a flat surface which is aligned parallel to the floor or to the direction of movement of the conveyor.
- a segmented belt or pallet belt is conventionally driven by means of a drive.
- the handrail must in this case be driven in such a way that it moves uniformly with the pallet band.
- the drive of the pallet belt via appropriate transmission, such as chain drive also drives the handrail.
- the movement of the handrail is rigidly coupled to the movement of the pallet belt.
- this rigid coupling of the handrail or the handrail with the pallet band is associated with a number of disadvantages in terms of energy consumption and wear.
- the energy consumption of a typical escalator with no load about 400 W, of which about 80% fall on the drive of the handrail. Only the remaining 20% fall on the drive of the pallet belt.
- the life of a handrail is substantially determined by the number of its turns, and thus can be increased if the number of turns can be reduced.
- the aim is to provide a passenger transportation device which can be operated in an energy-efficient and user-friendly manner at the same time.
- the present invention proposes a passenger transport device with the features of claim 1.
- the drive of a segmented belt or pallet belt can be coupled in a simple manner with a mechanism for moving the handrail, or decoupled from this. It is according to the invention only a single drive for driving the segmented belt and the pallet belt needed. According to the invention, the operation of a passenger transport device is possible in a particularly energy-saving manner, since the handrail is not necessarily moved during a movement of the segmented belt. At the same time, a passenger approaching the passenger transport device can easily be signaled by the movement of the segmented belt that the passenger transport device is in operation. Conveniently, the handrail is coupled with the belt drive of the segmented belt only when an actual need exists, so for example, a passenger enters the passenger transport device.
- the coupling device comprises a continuously variable transmission for stepless adjustment of the speed of the handrail relative to the speed of the segmented belt.
- control the coupling device by means of a control device, in particular as a function of a detected presence of at least one passenger in the surroundings or on the passenger transport device.
- a suitable sensor system for example a light barrier, can be provided, by means of which a signal can be given to a control device, which is expedient for its coupling of the handrail to the segmented band.
- the coupling device is designed as an electromagnetic, hydraulic, pneumatic or mechanical coupling. Such couplings require little space, work very quietly and prove to be robust and reliable in practice.
- magnetorheological or electrorheological couplings can be precisely and quickly controlled by appropriate application of a suitable magnetic or electric field in a simple manner, working very quietly.
- a magnetorheological or electrorheological fluid used in this case alters its consistency, for example from liquid to gel, to solid under the influence of the magnetic field or the electric field.
- These liquids can be sealed in a very good way to the outside, wherein they have a low internal friction in the separated state. Further, they have a better heat dissipation, whereby operation in a slip state over long periods can be easily maintained.
- the formation of the coupling device as a multi-plate clutch.
- two handrail bands of a handrail can be coupled independently of one another by the segmented band.
- This measure can be achieved, for example, that only a handrail, conveniently the handrail on which a user or passenger is supported, is moved with the segmented band.
- the second handrail can in this case remain in its decoupled with respect to the segmented band state and thus stand still.
- the energy consumption of a Wegbelieseinreichtung invention is further optimized.
- the passenger transport device is designed as an escalator, moving walk or as a conveyor belt.
- FIG. 1 shows the drive of a trained example as an escalator passenger transport device according to the prior art in a schematic representation.
- the escalator has a drive unit 102, a main drive chain 104, a main drive sprocket 106, two drive wheels 108 (left) and 108 '(right) for a segmented belt, in the case of an escalator so a step belt (not shown), a main drive shaft 110, a drive pinion 112 for a handrail having two handrail bands (not shown), a handrail drive chain 114, a sprocket 116, a handrail drive shaft 118, and a handrail 120, 120 'for the handrail bands of the handrail, respectively.
- the drive unit 102 drives the main drive chain, which drives the two drive wheels 108, 108 'connected to the main drive shaft 110 for the step belt.
- the step belt is driven by and supported by the drive wheels 108, 108 '.
- the main drive shaft 110 also drives the drive pinion 112.
- the rotation of the drive pinion 112 is transmitted via the drive chain 114 and the sprocket 116, to the drive shaft 118 of the handrail.
- FIG. 2 is a first preferred embodiment of the invention (for example, also designed as an escalator) passenger transport device according to the invention shown in a corresponding representation purely schematically. Same or similar components, as in FIG. 1 have been described are provided with the same reference numerals.
- the escalator here designated 200, has two clutches 222, 222 'for the two handrail straps of the handrail, a handrail control unit 224 and a main control unit 226 for the escalator as a whole.
- the couplings 222, 222 ' are detachably formed. This makes it possible to jointly drive the step belt and the handrail by means of the drive unit 102 in a first, coupled operating state. In a second, decoupled operating state However, it is also possible to decouple the handrail from the step band, and so for example to let the handrail stand still while the step band is kept in motion. This is a particularly energy-efficient operation of escalators realized.
- the clutches 222, 222 ' are individually and independently controllable by the control unit 224.
- the speed of the handrail can be adjusted differently from the speed of the step belt.
- the main control unit 226 is adapted to control the movement of the escalator in response to a desired speed as well as, for example, a carried load, ie, in particular, the entirety of the passengers being carried.
- the handrail control unit 224 communicates with the main control unit via a suitable communication channel, and is particularly designed to control the clutches 222, 222 '.
- FIG. 3 is a further embodiment of the passenger transport device according to the invention (hereby designated by 300) shown in a corresponding representation. Again, components already described are provided with the same reference numerals.
- the embodiment according to FIG. 3 is different from the one of FIG. 2 in that the coupling elements of the coupling 316 can only be actuated together, a movement of the handrail bands 120, 120 'independently of one another is therefore not possible. This control is characterized by a particular simplicity, and is suitable for a variety of applications or situations.
- coupling device of a passenger transport device 400 is formed as a viscous coupling and 422, 422 'designated.
- a viscous coupling the rotational movement of the shaft 118 (input side) is transmitted to a first disc or lamella 423, which transmits it to a fluid provided between this disc and a further disc 424, which in turn the second disc 424 (output side) drives.
- the viscous coupling is designed as a magnetorheological or electrorheological coupling.
- FIG. 5 is shown as passenger transport means an escalator 500 schematically, in which the movement of the handrail is coupled via a continuously variable transmission or CVT gear 502 to the movement of the step band.
- the CVT transmission 502 Continuous Variable Transmission
- the CVT transmission 502 has on the drive side a wedge disk pair 518 and on the output side a wedge disk pair 520.
- Drive side and output side of the CVT 502 are interconnected via a V-belt 502.
- the distance between both wedge disk pairs 518, 520 is changeable.
- the distance of the output-side wedge disks 520 is regulated by a spring 522.
- the V-belt 502 is circular at both ends.

Description
Die vorliegende Erfindung betrifft eine Personenbeförderungseinrichtung nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a passenger transport device according to the preamble of patent claim 1.
Aus dem Stand der Technik sind Fördereinrichtungen zum Befördern von Personen, insbesondere Fahrtreppen, Fahrsteige oder Förderbänder, in vielfältigen Ausführungen bekannt.Conveying devices for transporting people, in particular escalators, moving walks or conveyor belts, in various designs are known from the prior art.
Derartige Einrichtungen werden beispielsweise zum Befördern von Personen zwischen Ebenen eines Gebäudes (Fahrtreppen) oder entlang eines ebenen Weges (Fahrsteige) verwendet.Such devices are used for example for transporting people between levels of a building (escalators) or along a level path (moving walks).
Eine Fahrtreppe umfasst beispielsweise eine Mehrzahl von Stufen oder ein Band bzw. einen Gurt, auf dem zu fördernde Personen stehen, um von einer Stelle zu einer anderen befördert zu werden. Zusätzlich ist in der Regel ein Handlauf vorgesehen, der über eine Balustrade läuft und eine Oberfläche bereitstellt, an der sich beförderte Personen beispielsweise festhalten können.For example, an escalator includes a plurality of steps or a belt on which people to be conveyed are to be carried from one location to another. In addition, a handrail is usually provided, which runs over a balustrade and provides a surface on which carried people can hold for example.
Ein derartiger Handlauf weist typischerweise zwei Handlaufbänder mit jeweils einer ebenen Oberfläche auf, die parallel zum Boden oder zu der Bewegungsrichtung der Beförderungseinrichtung ausgerichtet ist. Ein segmentiertes Band bzw. Palettenband wird herkömmlicherweise mittels eines Antriebs angetrieben. Der Handlauf muss hierbei derart angetrieben werden, dass er sich gleichförmig mit dem Palettenband bewegt. Herkömmlicherweise treibt der Antrieb des Palettenbandes über entsprechende Getriebe, beispielsweise Kettengetriebe, auch den Handlauf an.Such a handrail typically has two handrail bands each having a flat surface which is aligned parallel to the floor or to the direction of movement of the conveyor. A segmented belt or pallet belt is conventionally driven by means of a drive. The handrail must in this case be driven in such a way that it moves uniformly with the pallet band. Conventionally, the drive of the pallet belt via appropriate transmission, such as chain drive, also drives the handrail.
Hierbei ist die Bewegung des Handlaufs starr an die Bewegung des Palettenbandes gekoppelt.Here, the movement of the handrail is rigidly coupled to the movement of the pallet belt.
Diese starre Kopplung des Handlaufs bzw. der Handlaufbänder mit dem Palettenband ist jedoch mit einer Reihe von Nachteilen hinsichtlich des Energieverbrauchs und des Verschleißes verbunden. Beispielsweise beträgt der Energieverbrauch einer typischen Fahrtreppe ohne Last etwa 400 W, wovon ca. 80 % auf den Antrieb der Handlaufbänder fallen. Lediglich die verbleibenden 20 % fallen auf den Antrieb des Palettenbandes. Des Weiteren wird die Lebensdauer eines Handlaufbandes im Wesentlichen von der Anzahl seiner Umläufe bestimmt, und kann somit erhöht werden, wenn die Anzahl der Umläufe verringert werden kann.However, this rigid coupling of the handrail or the handrail with the pallet band is associated with a number of disadvantages in terms of energy consumption and wear. For example, the energy consumption of a typical escalator with no load about 400 W, of which about 80% fall on the drive of the handrail. Only the remaining 20% fall on the drive of the pallet belt. Furthermore, the life of a handrail is substantially determined by the number of its turns, and thus can be increased if the number of turns can be reduced.
Es ist bekannt, Personenbeförderungseinrichtungen verlangsamt anzutreiben, wenn gerade kein Benutzer transportiert wird. Bei derartigen Langsamfahrten werden beispielsweise Geschwindigkeiten von 0,1 m/s eingestellt, wobei eine typische Normalfahrt mit Geschwindigkeiten von etwa 0,5 m/s arbeitet. Auch hier kommt es, wenn gleich im verminderten Umfang, zu den oben beschriebenen Problemen bezüglich Energieverbrauch und Lebensdauer des Handlaufbandes.It is known to drive passenger vehicles slower when no user is being transported. In such low speeds, for example, speeds of 0.1 m / s are set, with a typical normal travel operating at speeds of about 0.5 m / s. Again, albeit to a lesser extent, there are the above-described problems in terms of energy consumption and life of the handrail.
Um Energie einzusparen, ist es auch bekannt, Personenbeförderungseinrichtungen lediglich dann anzutreiben, wenn die Einrichtung gerade von einem Benutzer verwendet wird. Typischerweise setzt sich die Einrichtung in Bewegung, kurz bevor eine Person sie betritt. Als nachteilig wird jedoch angesehen, dass es für eine Person, die sich der Einrichtung nähert, zunächst nicht möglich ist, zu erkennen, ob diese aktuell betriebsbereit ist oder nicht, wenn das Palettenband nicht in Bewegung ist. Hierdurch ist die Benutzerfreundlichkeit insgesamt beeinträchtigt.In order to save energy, it is also known to drive passenger transport equipment only when the equipment is being used by a user. Typically, the device sets in motion just before a person enters it. A disadvantage, however, considered that it is initially not possible for a person approaching the device to recognize whether this is currently operational or not, if the pallet belt is not in motion. As a result, the overall user experience is impaired.

Vor diesem Hintergrund wird angestrebt, eine Personenbeförderungseinrichtung zur Verfügung zu stellen, welche energieeffizient und gleichzeitig bedienerfreundlich betrieben werden kann.Against this background, the aim is to provide a passenger transportation device which can be operated in an energy-efficient and user-friendly manner at the same time.
Ausgehend von dem dargestellten Stand der Technik schlägt die vorliegende Erfindung eine Personenbeförderungseinrichtung mit den Merkmalen des Patentanspruchs 1 vor.Starting from the illustrated prior art, the present invention proposes a passenger transport device with the features of claim 1.
Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung.Advantageous embodiments are the subject of the dependent claims and the following description.
Erfindungsgemäß ist der Antrieb eines segmentierten Bandes bzw. Palettenbandes in einfacher Weise mit einem Mechanismus zum Bewegen des Handlaufs koppelbar, bzw. von diesem entkoppelbar. Es wird erfindungsgemäß lediglich ein einziger Antrieb zum Antreiben des segmentierten Bandes und des Palettenbandes benötigt. Erfindungsgemäß ist der Betrieb einer Personbeförderungseinrichtung in besonders energiesparender Weise möglich, da der Handlauf bei einer Bewegung des segmentierten Bandes nicht notwendigerweise mitbewegt wird. Gleichzeitig kann einem Passagier, der sich der Personbeförderungseinrichtung nähert, durch die Bewegung des segmentierten Bandes in einfacher Weise signalisiert werden, dass die Personbeförderungseinrichtung in Betrieb ist. Zweckmäßigerweise wird der Handlauf erst dann mit dem Bandantrieb des segmentierten Bandes gekoppelt, wenn ein tatsächlicher Bedarf besteht, also beispielsweise ein Passagier die Personbeförderungseinrichtung betritt.According to the invention, the drive of a segmented belt or pallet belt can be coupled in a simple manner with a mechanism for moving the handrail, or decoupled from this. It is according to the invention only a single drive for driving the segmented belt and the pallet belt needed. According to the invention, the operation of a passenger transport device is possible in a particularly energy-saving manner, since the handrail is not necessarily moved during a movement of the segmented belt. At the same time, a passenger approaching the passenger transport device can easily be signaled by the movement of the segmented belt that the passenger transport device is in operation. Conveniently, the handrail is coupled with the belt drive of the segmented belt only when an actual need exists, so for example, a passenger enters the passenger transport device.
Zweckmäßigerweise weist die Kopplungseinrichtung ein stufenloses Getriebe zur stufenlosen Einstellung der Geschwindigkeit des Handlaufs relativ zur Geschwindigkeit des segmentierten Bandes auf.Conveniently, the coupling device comprises a continuously variable transmission for stepless adjustment of the speed of the handrail relative to the speed of the segmented belt.
Besonders bevorzugt ist, mittels einer Steuereinrichtung die Kopplungseinrichtung insbesondere in Abhängigkeit von einer erfassten Anwesenheit wenigstens eines Passagiers in der Umgebung oder auf der Personenbeförderungseinrichtung zu steuern. Insbesondere kann eine geeignete Sensorik, beispielsweise eine Lichtschranke, vorgesehen sein, mittels der einer Steuerungseinrichtung ein Signal gegeben werden kann, das seine Kopplung des Handlaufs mit dem segmentierten Band zweckmäßig ist.It is particularly preferred to control the coupling device by means of a control device, in particular as a function of a detected presence of at least one passenger in the surroundings or on the passenger transport device. In particular, a suitable sensor system, for example a light barrier, can be provided, by means of which a signal can be given to a control device, which is expedient for its coupling of the handrail to the segmented band.
Besonders bevorzugt ist, dass die Kopplungseinrichtung als elektromagnetische, hydraulische, pneumatische oder mechanische Kupplung ausgebildet ist. Derartige Kupplungen benötigen wenig Bauraum, arbeiten sehr leise und erweisen sich in der Praxis als robust und zuverlässig.It is particularly preferred that the coupling device is designed as an electromagnetic, hydraulic, pneumatic or mechanical coupling. Such couplings require little space, work very quietly and prove to be robust and reliable in practice.
Besonders bevorzugt ist der Einsatz von magnetorheologischen oder elektrorheologischen Kupplungen. Derartige Kupplungen sind durch entsprechendes Anlegen eines geeigneten magnetischen oder elektrischen Feldes in einfacher Weise präzise und schnell steuerbar, wobei sie besonders leise arbeiten. Eine hierbei eingesetzte magnetorheologische oder elektrorheologische Flüssigkeit verändert unter Einfluss des Magnetfeldes bzw. des elektrischen Feldes ihre Konsistenz beispielsweise von flüssig über gelförmig zu fest. Diese Flüssigkeiten lassen sich in sehr guter Weise nach außen abdichten, wobei sie im getrennten Zustand eine geringe innere Reibung aufweisen. Ferner weisen sie eine bessere Wärmeableitung auf, wodurch ein Betrieb in einem Schlupfzustand über längere Zeiten problemlos aufrechterhalten werden kann.Particularly preferred is the use of magnetorheological or electrorheological couplings. Such couplings can be precisely and quickly controlled by appropriate application of a suitable magnetic or electric field in a simple manner, working very quietly. A magnetorheological or electrorheological fluid used in this case alters its consistency, for example from liquid to gel, to solid under the influence of the magnetic field or the electric field. These liquids can be sealed in a very good way to the outside, wherein they have a low internal friction in the separated state. Further, they have a better heat dissipation, whereby operation in a slip state over long periods can be easily maintained.
Besonders bevorzugt ist auch die Ausbildung der Kopplungseinrichtung als Lamellenkupplung.Particularly preferred is the formation of the coupling device as a multi-plate clutch.
Gemäß einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Personenbeförderungseinrichtung sind zwei Handlaufbänder eines Handlaufs unabhängig von einander von dem segmentierten Band koppelbar. Mit dieser Maßnahme kann beispielsweise erreicht werden, dass lediglich ein Handlaufband, zweckmäßigerweise das Handlaufband, auf dem sich ein Benutzer bzw. Passagier abstützt, mit dem segmentierten Band bewegt wird. Das zweite Handlaufband kann hierbei in seinem bezüglich des segmentierten Bandes entkoppelten Zustand bleiben und somit stillstehen. Hiermit ist der Energieverbrauch einer erfindungsgemäßen Personenbeförderungseinreichtung weiter optimierbar.According to a particularly preferred embodiment of the passenger transport device according to the invention, two handrail bands of a handrail can be coupled independently of one another by the segmented band. This measure can be achieved, for example, that only a handrail, conveniently the handrail on which a user or passenger is supported, is moved with the segmented band. The second handrail can in this case remain in its decoupled with respect to the segmented band state and thus stand still. Hereby, the energy consumption of a Personenbeförderungseinreichtung invention is further optimized.
Zweckmäßigerweise ist die Personenbeförderungseinrichtung als Fahrtreppe, Fahrsteig oder als Förderband ausgebildet.Conveniently, the passenger transport device is designed as an escalator, moving walk or as a conveyor belt.
