Definitions
- the present invention relates to a method for controlling a closing movement of a door of an elevator car in the event of a power failure, a corresponding device, a method for retrofitting a door of an elevator car, a door for an elevator car and an elevator system.
- the door can be equipped with a friction brake. This component, which is not used in regular operation, causes additional costs.
- a drive motor of the door can be used as a dynamic brake in the event of a power failure by permanently wiring the drive motor as a generator during the power failure. This requires a special design of the drive motor.
- US 2021/292129 Al describes a control device for an elevator door.
- an elevator system with at least one door according to the fourth aspect of the invention is presented.
- An elevator system can be a passenger transport system.
- the elevator system can have at least one elevator car with at least one door.
- the door can in particular be a sliding door.
- the door can be opened and closed motorically using a door drive. As long as the door drive is supplied with electrical energy, the door drive can exert force on the door and open, close or hold the door. In the event of a power failure, the de-energized door drive can no longer hold or move the door.
- the resulting unbraked door can be closed using a locking mechanism.
- the locking mechanism can have a mechanical energy storage.
- the energy storage can be, for example, a preloaded spring and/or a wound weight.
- the spring can be at one opening movement of the door.
- the weight can be pulled upwards during the opening movement.
- the energy stored in the energy storage drives a one-time closing movement of the door. After the closing movement, the amount of energy stored in the energy storage is essentially used up.
- the door drive is operated by a control device.
- the control unit is supplied with electrical energy from a power supply.
- the power supply provides a supply voltage.
- the supply voltage can in particular be a low voltage, such as 24 volts DC.
- the control unit energizes the door drive using the supply voltage to operate the door.
- the supply voltage for the control device is buffered in an electrical energy storage of an intermediate device according to the second aspect of the invention.
- the electrical energy storage can be, for example, a battery and/or a capacity. If the power fails and consequently the supply voltage fails, the buffered electrical energy is released in a controlled manner by the device's control electronics.
- the buffered energy can be provided as replacement energy for the control unit's supply voltage. This means that the control unit can continue to supply power to the door drive and the door drive can control the closing movement driven by the locking mechanism.
- the delay period can depend on the design of the door, the locking mechanism and/or the door drive. For example, the delay period can be shorter than 5s, shorter than 2s, shorter than 1s or shorter than 0.5s.
- the delay period can be parameterized, for example, when the elevator system is commissioned or when the device is retrofitted.
- Deployment can be paused after a predefined deployment period.
- the door can be slowed down to a desired target speed by the door drive.
- the door can also be braked to a standstill.
- the door can be accelerated again using the locking mechanism.
- the provision time may depend on the control device.
- the provision time can depend on the duration of a boot process of the control device.
- the control unit can short-circuit door drive coils during the boot process.
- the closing movement can be slowed down by short-circuiting.
- the deployment time can also depend on the mass of the door.
- the provision time can be parameterized, for example, when the elevator system is commissioned or when the device is retrofitted.
- the approach presented here causes the door to slowly close if a power failure occurs while the door is open.
- a device is looped into the power supply of the door drive. If the power supply is intact, this simply forwards the 24 V DC to the door drive and at the same time charges a capacity or a battery.
