Definitions

  • the invention relates to a method for reducing the in the course of Redirecting one for a passenger conveyor, in particular an escalator or a moving walk, deployable chain occurring polygon effect.
  • the polygon effect is created by the square-shaped support of the chain on the Sprocket. As the angle of rotation increases, the effective radius varies Sprocket, whereby the chain speed between a maximum and a minimum value fluctuates.
  • the circulation effect is a consequence of the angular momentum, the from the sprocket to the chain links and thus to the steps or pallets is transmitted. After expiration of the chain from the sprocket this remains Angular momentum obtained first by the inertia of the system, resulting in the so-called curling the chain leads.
  • the angular momentum is due to friction in the chain or in the presence of a chain guide element by impact dismantled between chain and guide.
  • the aim of the subject invention is a method and a device provide by means of which the polygonal and circulation effects in substantially reduced while maintaining conventional orbital conditions to be able to maintain the smooth running of the passenger conveyor system in this way, in particular the escalator or the moving walkway, to optimize.
  • This goal is achieved on the one hand by a method of reducing the im Course of the chain deflection one for a passenger conveyor, in particular an escalator or a roller chain insertable chain occurring Polygon effect, by over the on the deflection wheel middle or immediately one acting on the rotational speed of the guide wheel different speed is superimposed.
  • This goal is further achieved by means of reduction in the course of the diversion of a for a passenger conveyor, in particular an escalator or a moving walkway, deployable chain occurring Polygon effect, with at least one, possibly with at least one Gear connected electric drive motor, the middle or immediate acting on the deflection wheel, wherein the drive motor with at least one Power supply unit, in particular a frequency converter, is connected, so that the drive motor with a non-constant speed is drivable.
  • AC asynchronous motors are used with the a power supply unit, such as a frequency converter, in Active connection are brought, so that the engine is driven in such a way can be that it rotates at a non-constant speed, which then, possibly with the involvement of a gearbox, in a corresponding manner to the respective deflection wheel acts.
  • the varying chain speeds, the are given at the chain enema are, by the subject invention as far as possible balanced or an adaptation takes place, so that the previously given shocks are compensated in the system.
  • the phase angle of the sprocket and / or the Circulation speed of the chain measured, the measured value or the Measured values are fed to a control device, these in prepared accordingly to the frequency converter.
  • the subject invention is in addition to a reduction of Polygon effect also the smooth running of the passenger conveyor system considerably increased without making any modifications on the mechanical side are.
  • Manufacturing tolerances of the deflecting wheel and / or the chain can by Interpolation of the control device or the power supply unit be stored, with the occurring in the operating state monitoring the phase angle or the chain rotation speed more Intervention options are given, which are particularly positive affect if the transport speed is between 0 and maximum varied.
  • the subject invention is versatile and with regard to the constantly falling in price electric or electronic components conventional mechanical modifications considered cheaper.
  • the subject invention is based on an embodiment in the Drawing and is described as follows.
  • the single figure shows a schematic diagram of an only hinted Passenger conveyor system, such as an escalator 1. Recognizable following components:
  • a guide wheel 2 which is equipped with a plurality of teeth 3, one out several links 4 existing link chain 5 and an electrical Drive motor, if necessary, with a not shown here Gear is in operative connection.
  • the connection between the Drive motor 6 and the deflection wheel 2 is by the drive member. 7 shown.
  • the running direction of the chain 5 or the deflection of the Guide wheel 2 is indicated by arrows.
  • This superposition is brought about by the fact that with the drive motor. 6 a frequency converter 8 is in operative connection, the drive motor. 6 such that it rotates at a non-constant speed and this non-constant speed via the drive member 7 in superimposed Way is transmitted to the guide wheel 2.
  • a control device 9 several control parameters can be stored, the basic pattern already existing escalators or moving walkways, so that at Standard versions to these basic settings can.
  • a Sensor 10 determines the phase angle of the deflection wheel 2 and this of the To make available control device 9.
  • Another parameter can be the Circulation speed of the chain 5, for example, via a another sensor 11 is measured, whereby these measured values of the Control device 9 are provided.
