Definitions

  • the invention relates to a method for controlling the brake (s) one Escalator or an escalator according to the generic part of the first Claim.
  • a disadvantage of the known brake is that the braking partly depending on the load, no equal braking distances - because depending on the load - are observable and that with certain constructive Circumstances of this size (e.g. excess length of moving walkways) it is necessary that technical limits for accommodation are reached here become.
  • the brake pads must wear more be calculated, which is a continuous for security reasons Adjustment of the mechanical brakes results.
  • DE- ⁇ -35 09 207 are a method and a device for braking of passenger conveyors, for example an escalator, at which the movement of the escalator is essentially independent of the Load and the direction of movement of the escalator in a controlled manner is braked.
  • the slowdown event is continuous with a Signal monitored and controlled, which is a speed converter, for example, a tachometer generator.
  • the windings one as DC motor is used to drive the AC motor, the electrodynamic braking effect generated in the engine in the Movement of the escalator a predetermined slowdown behavior causes.
  • the windings of the drive motor are used when braking preferably a pulsating DC voltage supplied by means of a Thyristor circuit is shaped and controlled by electronic Components controlled for the escalator on the basis of one Speed converter, e.g. a speedometer, delivered speed the escalator forms a reference speed value.
  • a Speed converter e.g. a speedometer
  • frequency converters used which may be mechanical brakes as service brakes make it largely dispensable.
  • the frequency converters provide however, components that are associated with an increased cost and may therefore not be desired by the customer.
  • a brake control device for Passenger conveying systems such as escalators or moving walks, are described.
  • the Device affects a sensor that measures the speed of the Passenger conveyor system measures (actual value) and a current speed signal generated in analog form. Furthermore, an analog control signal (Setpoint) generated. In the area of a downstream control device a comparison of the analog setpoints and actual values instead.
  • the controller generates an Control signal on the brake magnet of a brake device in retarding form, such that a gentle gradual Deceleration is made possible, the actual value being close to the setpoint should remain. With this device, the brake should be gradually, i.e. in in a quasi-analog form.
  • Another one High-frequency signal is provided as a control criterion for the brake gradually between 100% and 0 within a predefinable time interval % and between 0% and 100%, so that a gradual, i.e. non-linear braking of the passenger conveyor system is given.
  • Fluctuation of this high frequency signal in the specified form is the load actually given on the passenger conveyor system (number of people) no real account taken, so that with gradual braking the Personal system this from the users u. U. perceived as uncomfortable becomes.
  • the object of the invention is to provide a method for regulating the To further develop the brake (es) of an escalator or an escalator, that a control scheme independent of frequency converters is formed, the regardless of the given load on the escalator or the Rollshausen can optionally also be integrated into existing systems, without special assembly and cost expenditure.
  • a braking device operating according to the method according to the invention can, in analogy to US Pat. No. 4,664,247, at least one, in particular spring-loaded brake, e.g. a shoe brake, which include at least one brake magnet can be controlled, which, from this level Technology differs, however, from a discontinuous comparison of target and actual values performing controller is controllable.
  • at least one, in particular spring-loaded brake e.g. a shoe brake, which include at least one brake magnet
  • the subject of the invention thus enables one, possibly also in the case of existing ones Systems that can be retrofitted, preferably a closed control loop, without larger costs and assembly costs on the one hand in new and on the other hand in existing systems can be integrated.
  • Braking device can thus the speed of the escalator or Moving sidewalks defined with essentially constant deceleration except for the value 0 m / s.
  • a braking ramp is activated, whereby can be decelerated uniformly and linearly, namely under Compliance with the braking distance required in the relevant guidelines.
  • the Controller contains as setpoint (s) delay values that are discontinuous preferably with speed values of the drive motor of the escalator or the Moving sidewalks.
  • the brake magnet controlled independently of the power supply of the drive motor become. This does require a bit more effort, since one independent power supply must be provided; for special Use cases, especially from a safety perspective however, this area of application is regarded as a further alternative to the To further develop the subject of the invention in a meaningful manner.
  • the subject of the invention is applicable to all types of escalators and escalators using brakes. However, it is preferred are applied to spring-loaded brake levers Chocks.
  • Figure 1 shows the partial representation of the brake 1 of a not shown Escalator.
  • a brake drum 2, a brake lever 3, can be seen Spring assembly 4, a bracket 5 and a brake magnet 6 in this Example is operated with direct current.
  • FIG. 1 shows the same components as already described. Furthermore the following components can also be seen: the housing 7 of the Drive motor 8 and sensors 9 (e.g. proximity switch initiators) for Tapping the speed of the drive motor 8.
  • sensors 9 e.g. proximity switch initiators
  • the overspeed and underspeed of the drive 8 designed as an electric motor is detected via the initiators 9 and not shown Motor guard provided.
  • the escalator In the normal state of the escalator is the on the brake lever 3 arranged shoe brake 10 released, d. H. does not lie on the drive motor 8 designed as a brake drum.
  • the spring 4 When switched off the drive, the spring 4, the brake lever 3 on the drive motor Press the 8 forming brake drum and generate a braking torque.
  • the Brake lever 3 is pressed onto the brake drum and brings that Step belt to a standstill.
  • Such mechanically acting braking devices 1 belong to the state of the Technology, including any other, possibly non-mechanical, brake can be used.
  • FIG. 3 shows a schematic diagram of a control scheme for the braking device 1 according to Figures 1 and 2.
  • Reference numeral 11 is the power supply addressed.
  • Reference numeral 12 relates to a controller and that Reference numeral 13 a brake magnet.
  • the electric motor 8 is also indicated how the brake lever 3 and the speed sensors 9.
  • the controller 12 are preferably several setpoint specifications with regard to possible Deceleration ramps filed. This example uses a discontinuous Determination of the respective speed of the drive motor 8 via the Speed sensors 9 causes and available to the controller 12 as an actual value posed.
  • the controller 12 is a discontinuous target-actual comparison made, the results of the brake magnet 13 as control values Be made available so that this in turn regulates the Brake lever 3 can act.
