Definitions

  • the invention relates to a drive for a curtain in the form of a smoke curtain, roller shutter, roller shutters, garage doors, Feuerschutzbehanges, room divider or the like with an emergency power supply for an electronic limit switch according to the preamble of claim. 1
  • a drive has a drive motor for moving the curtain between an open and closed position and a working current brake, which causes a slowing of the curtain when rolling and serves to keep the curtain in a position, the so-called end position.
  • the drive has an electronic limit stop for activating or deactivating the operating current brake and for switching off the drive motor.
  • the electromotive drive itself is usually made of a tubular motor, which is coupled to the electromagnetic Anlagenstrombremse.
  • the operating current brake is activated and thus effective as long as the electric motor is not actuated and holds the curtain in the end position between an open and closed position.
  • the curtain for example due to gravity or braked by a centrifugal brake, is moved into the closed position. After restoration of the operating voltage, it is necessary that the curtain is returned to the original end position.
  • a fire protection drive of the aforementioned type is known, with a drive motor for rolling a curtain, with a working current brake for braking the curtain and with a brake motor connected to the working current brake.
  • the voltage generated by the brake motor is used when unrolling the curtain to activate the working current brake.
  • the brake motor has an output voltage corresponding to the operating voltage of the operating current brake.
  • the working current brake is deactivated.
  • the smoke curtain winds due to gravity, which is rotated via the drive shaft, the transmission and the drive shaft of the DC motor.
  • the brake motor is operated in this case as a generator and generates the operating voltage of the working current brake. The smoke protection curtain is thus lowered in a danger trap braked to the closed position.
  • a braking device for a smoke curtain, curtain or the like which has a means acting by friction brake.
  • This brake responds at a rotational speed above a rated speed of the winding shaft and ensures a controlled lowering of the curtain.
  • uncontrolled shutdown of the curtain may occur. This is prevented by the fact that the brake formed as a centrifugal brake acts from a certain upper speed of the motor shaft.
  • a device for controlling the arrival and withdrawal of a roller door is known.
  • a processing unit is provided, which is supplied with electrical energy via a control circuit, wherein the processing unit controls a motor to a first direction for moving the free end of the roller door to a predetermined retraction position and in a second direction for moving the free end of the roller door to effect a given pull-out position.
  • the processing unit determines the current position information before the motor rotation signals, which is monitored during a movement of the free end of the roller door from one of the predetermined extension and retraction position to a current position, and stores the current position information in a memory, so that the processing unit in is able to control the motor for moving the free end of the roller door from the current position to one of the predetermined extension and retraction positions.
  • the processing unit also controls the motor that moves the roller door.
  • the EP 0 959 222 A2 describes a drive for a fire door and a braking device connected to the drive.
  • the brake can be controlled by means of an electronically controlled, powered by a DC power lowering device.
  • the lowering speed of the door can be controlled or its reduction can be controlledly delayed in the event of an alarm.
  • a fire protection drive in which after the automatic closing of a fire door in case of alarm, the re-commissioning should be facilitated.
  • the system is designed so that when reaching the closed position of the door, either after a fire alarm or after failure of the power supply, this can be made directly operational again by pressing a switch or reconnecting the power.
  • roller shutter drives storage of the position or the end position of the curtain at the time of power failure, in the event that the operating voltage is available again, the curtain to move back to exactly this position.
  • the invention is therefore based on the object to provide a drive with an emergency power supply for an electronic Endabscnies according to the preamble of claim 1, which makes it possible to store the position or the end position of the curtain at the time of power failure.
  • the drive for a curtain comprises a drive motor for moving the curtain between an open and a closed position, a Hästrombremse for braking the curtain during unwinding and holding the curtain in a predetermined position and an electronic limit for activating or deactivating the working current brake and to turn off the drive motor.
  • the drive has an energy storage for energizing the electronic limit in case of failure of the operating voltage.
  • the position of the blind is determined at the time of power failure, so it is stored and retrieved when the operating voltage is restored by the control of the drive to the blind, yes in case of failure the operating voltage has moved into the closed position, to move back to the original position before the power failure.
  • the electronic limit switch-off is an electronic analysis system for determining data, in particular end positions and / or switch-off data of the curtain, and a Data storage for storing this data, wherein the data can be read in a controller.
  • the end positions of the blind are determined by the analysis electronics at the time of power failure by counting the number of revolutions of the winding shaft from the original position to the closed position and stored in the data memory and retrieved by the controller when producing the operating voltage.
  • a mechanical method of hanging, for example by a hand crank, after a power failure back to the original end position is no longer necessary.
  • the electronic limit switch can be supplied by the energy store in the event of a failure of the operating voltage, so that the end position can be determined and stored in the data memory at the time of the power failure by the analysis electronics of the electronic limit switch. So that the number of revolutions of the winding shaft moving downward can be counted and the end position of the blind can be determined from these data, the electronic limit stop can be supplied by the energy store.
  • the electronic limit switch has an output voltage corresponding to the charging voltage of the energy store.
  • the energy store can be charged in a standby mode of the drive, that is to say when the normally closed brake is closed. This ensures that the energy storage is maximally charged when the curtain is in a rest position or end position, that is, the curtain is not moved.
  • the electrical voltage required for the operation of the drive is used to charge the energy storage, other power sources are not necessary, what is also directly affects the manufacturing cost of the drive. Also, no additional space for additional power sources is needed, creating a very compact form of the drive is possible.
  • the energy store is a double-layer capacitor, in particular a so-called "gold cap”.
  • These capacitors fall under the family of supercapacitors, which have very high capacitance values. In addition, they can be quickly loaded and unloaded and survive a high number of switching cycles.
  • the drive has a centrifugal brake.
  • a centrifugal brake As a result, an unintentional rolling or falling-down of a curtain or shutter, especially in the event of a malfunction, is prevented quickly and reliably.
  • Such a brake can be carried out completely mechanically, so that even in the event of a power failure, a controlled unwinding of the curtain is realized.
  • the drive is designed as a tubular drive.
  • Such tubular drives are standardized and are therefore often preferred for drives with special dimensions and special shapes.
  • the compactness of the drive saves storage and transport costs.
  • FIG. 1 is a drive 1, in particular a tubular drive, for a curtain 2 in the form of a smoke curtain, roller shutter, roller shutter, garage doors, Feuerschutzbehanges, room divider, awnings, screens or the like.
  • the drive 1 has a drive motor 3 for rolling up the curtain 2, a planetary gear 10 and a working current brake 4 for braking the curtain 2 for a controlled unwinding.
  • An electronic limit switch 5 activates or deactivates the working current brake 4 and serves to switch the drive motor 3.
  • a centrifugal brake 9 assists the rolling of the curtain 2 during a power failure in the closed position and brakes the downward movement, so that damage to the curtain 2 is prevented by too rapid downward movement and even under the closing curtain 2 people are protected from injury.
  • the effect of the centrifugal brake occurs only at a previously defined speed of the winding shaft when rolling the curtain 2 and brakes the downward movement of the curtain 2 until it finally comes to a stop in the closed position.
  • the centrifugal brake 9 operates independently of external power supply.
  • the respective positions of the blind 2 or the so-called end positions are stored during normal operation.
  • the electronic limit switch 5 is taught by the respective positions or the end positions are stored in a data memory 7 of the electronic Endabscnies 5.
  • the drive 1 is controlled by the stored in the electronic Endabscnies 5 data.
  • the electronic limit switch 5 In the event that there is a power failure of the drive, for example in an emergency or for maintenance purposes, the electronic limit switch 5 is no longer supplied with the operating voltage.
  • an energy storage 6 is provided for supplying the electronic Endabscnies 5 in case of elimination of the operating voltage. This makes it possible to determine the position of the curtain 2 immediately before the elimination of the operating voltage.
  • the necessary electrical energy for operating the analysis electronics is kept ready by the energy store 6, which supplies the electronic limit switch 5 with voltage for the time of counting the revolutions of the winding shaft until these data are evaluated.
  • the electronic limit switch 5 has an output voltage corresponding to the charging voltage of the energy store 6.
  • the energy store 6 is designed as a capacitor, in particular as a double-layer capacitor or as a so-called "gold cap”. This gives a particularly high storage capacity.
  • double-layer capacitors can be charged and discharged quickly and survive a high number of switching cycles.
  • the electronic analysis of the electronic Endabscnies 5 for counting and storing the revolutions in the data memory 7 can be supplied by the energy storage 6 preferably up to 120 seconds with voltage. Even with fire doors 2 with a height of up to 8 m results in a maximum travel of the gate 2 of about 8 m at a speed of about 0.3 m / s, a travel time of the gate of about 30 seconds. The correspondingly dimensioned storage time of the energy store is therefore completely sufficient for counting and storing the revolutions of the winding shaft.
