Definitions
- the invention relates to a method for stopping Passenger conveyor according to the preamble of Claim 1.
- the holding brake ideally has none Easing. This means that no friction braking takes place, which leads to an unpredictable operational safety of the Holding brake can lead.
- the invention has for its object a method of to propose the type mentioned above, which the does not have the aforementioned disadvantages and Operational reliability of the holding brake increased.
- the activation of the holding brake shortly before standstill the passenger conveyor means that the holding brake is activated when the passenger conveyor at Delay is still in motion, that is, when the Drive motor is not yet completely stopped.
- the Holding brake is preferably at a speed of about 20% of the normal speed of the Passenger conveyor activated so that a Friction braking takes place. This controlled activation the holding brake increases the operational safety of the Operating system.
- the frequency converter is advantageous only with the The holding brake becomes effective. This has the Advantage that there is no jerk of the engine, which is a uncomfortable acceleration and a disturbing noise for which can be passengers. Such an optimized stopping the passenger conveyor increases driving comfort.
- the holding brake is advantageously activated when the Passenger conveyor a speed of 0.1 m / s has reached in the braking ramp. This has the advantage that the speed of the passenger conveyor constantly is monitored and the holding brake at the correct one Speed slips.
- the invention also has the following advantages: Due to the smooth stopping of the engine, this creates Drive system no unnecessary noise and is wear-free, which increases the life of the component.
- Fig. 1 shows a graphic representation of a load-independent braking of the step pallet belt one Escalator or moving walk.
- Braking There are two types of Braking, namely electric braking and one Holding brake.
- the electric braking system is used for the Service braking is used, with a drive motor 4 over your frequency converter 2 via a set braking ramp 1 is braked. If the electrical braking is interrupted, the brake 3 continues to brake.
- the Holding brake 3 is an electromechanical brake that operates on the motor shaft of the drive motor 4 preferably looks form-fitting. When the holding brake is applied alone 3 are those defined in the applicable standards / guidelines Braking distances maintained.
- the braking can be activated due to an emergency stop or an incorrect response from one Security element take place.
- the speed v is in Function of time t given, with vN the normal Speed of the passenger conveyor is.
- the braking ramp 1 by the frequency converter 2 is activated, defines a predetermined braking distance a predetermined time t.
- the speed v of the Passenger conveyor is therefore defined with a Deceleration brought to the value 0 m / s.
- the braking ramp 1 of the frequency converter 2 is activated and braked with an essentially even deceleration.
- the holding brake 3 is applied to the Time t1, just before the Passenger conveyor.
- Frequency converter 2 is only switched off when if the holding brake has already started to work. The frequency converter 2 is thus switched off when the Engine 4 is already stopped. This leads to significant Advantages for the operation of the engine 4. Switching off the Frequency converter 2 usually does not take place linear. There are jerks that lead to unwanted noise or Damage to the gearbox or malfunction in the network.
- FIG. 2 shows a schematic representation of a Brake system according to an embodiment of the invention.
- the Frequency converter 2 is connected to the motor via switching elements 5 4 connected.
- the energy supply 6 feeds the Frequency converter 2, which with a control unit 7 in Active connection is established.
- the control unit 7 is also with the Switching elements 5 and with a brake magnet 8 in Operatively connected.
- the Monitoring of security elements such as the Security Circle instead.
- Triggering one Security element is detected by the control unit 7 which signals the frequency converter 2, an electrical Braking means controlled, soft Initiate braking.
- the safety circuit is interrupted, the contacts of the switching elements 5 are closed held so that the frequency converter 2 during the electrical braking can always act on the motor 4.
- the speed of the passenger conveyor will constantly measured. This can be done for example by a Speed sensor of the engine 4 take place. Shortly before the Standstill of the passenger conveyor, preferably at at a speed of 0.1 m / s, the holding brake 3 falls on.
