Definitions

  • the invention relates to a turnstile with a housing, a drive shaft, and locking arms protruding from it at an angle, each of which extends in the locked position approximately at right angles to the direction of passage, with a drive motor, which in particular after checking the access authorization of a passing user can be set in motion without contact in order to turn the next locking arm of the turnstile into the locking position and a method for its control.
  • Such a turnstile can be found, for example, in AT-B 389 736.
  • Proximity sensors (not explained in more detail) with a switching distance of approx. 5 cm recognize the presence and speed of the passing person and set the drive motor in motion, so that the turnstile is driven at a speed adapted to the passage speed. Since each locking arm must be equipped with a proximity sensor, and the signals emitted by the respective sensor must be transmitted into the housing via the rotating shaft, the structure is relatively complicated and also prone to failure.
  • a turnstile is known from SU-A 1 476 507, in which a light beam network is formed below the cone described by the blocking arms, which network supplements the turnstile.
  • the turnstile has a brake, by means of which the turnstile can be locked in any position, with no particular locking position having to be determined, since the light beam network recognizes an unauthorized passage in any case.
  • the invention has now set itself the task of achieving a simpler structure and greater functional reliability in the case of a turnstile which intervenes when an authorized passerby approaches.
  • the drive of the turnstile is switched on.
  • the sensor is installed below or above the drive shaft in the housing, so that the signal can be transmitted to the motor control in the usual way via fixed lines.
  • the optoelectronic sensor comprises at least one light scanner which is responsive to changes in reflection of an emitted light beam and which is equipped with an external light and background suppression.
  • the transmitted detection beam is reflected by the passing user.
  • the reflected light strikes a first light receiver, which is the one received
  • a first embodiment of the turnstile provides that the blocking position of the blocking arm lies in the center in the detection area of the optoelectronic sensor.
  • the optoelectronic sensor comprises two light scanners, the detection beams of which are at a small angle on both sides of the blocking arm.
  • turnstile drive is only put into operation when the first light switch in the direction of passage responds; however, if the second light button responds first, a brake can be activated.
  • a turnstile released on the basis of a positive control should be set in rotation by the user as soon as it is ready for passage, so that the subsequent motor drive takes place at the expected moment.
  • the released arm is released after pressure on the locking arm
  • Such a control can also be achieved with the turnstile according to the invention if the turnstile has a stopping position lying at an angle after the blocking position, and if the optoelectronic sensor is arranged in the passage direction behind the blocking arm standing in the blocking position at an angle between the blocking position and the stopping position.
  • a method for controlling the turnstile provides that a positive control result
  • the drive motor is put into operation so that the blocking arm is rotated from the blocking position into the subsequent stopping position, in which the detection beam of the light button can detect the user, and that the blocking arm is rotated further from the stopping position based on a detection signal of the light button until the next blocking arm is in the locked position. Since this means that it is not necessary to apply the locking arm either in the locked position or in the stopping position, the turnstile can also be passed on skis and on slightly rising floors by smaller children as well as adults, without causing difficulties.
  • a DC motor which can be short-circuited in the stopping position, is used in particular to drive the turnstile. Furthermore, it is preferably provided that a worm wheel is arranged on the drive shaft, into which a non-locking worm engages, on the shaft of which a magnetic brake and a direction-of-rotation detection device are provided, and which is driven by the motor via a traction means.
  • the magnetic brake can be activated in particular in the locked position.
  • FIG. 1 shows an oblique view of a first exemplary embodiment of the turnstile
  • FIG. 2 shows a schematic top view of a blocking position
  • FIG. 3 shows a schematic top view of a stopping position
  • FIG. 4 shows a schematic top view of a release position of the user
  • FIG. 5 shows a Oblique view of a second exemplary embodiment of the turnstile
  • FIG. 6 shows a schematic plan view of the blocking position thereof
  • FIG. 7 shows a schematic representation of the gear area.
  • the housing 2 of a turnstile 3 is arranged on a frame 1 so that it can be adjusted in height.
  • the turnstile is assigned to a through lane and has three locking arms, of which the upward locking arm 4 is in a locking position which lies at an angle of approximately 10 ° in front of a center line drawn in broken lines.
  • a worm wheel 11 is fastened on the shaft of the turnstile 3, into which a non-inhibiting worm 12 engages, which is driven by an electric drive motor 16 via a traction means 13.
  • the turnstile 3 is held in the locked position of each locking arm 4 by an electromagnetic brake 8 which engages the shaft of the worm 12.
  • a direction of rotation and angle of rotation detection disk 14, to which a detector 15 is assigned, is also arranged on this shaft.
  • the turnstile is also equipped with an optoelectronic sensor 5 the drive motor 16 is switched, and in the embodiment according to FIGS. 1 to 4 is provided with a control device 7, to which a transceiver unit 8 shielded from the environment, a magnetic card reader 9 with a display 10 and a corresponding control circuit are assigned .
  • FIG. 2 shows the locked position of the turnstile. A user 18 standing in front of the locking arm 4 cannot be detected by the detection beam, since this is behind the locking arm. If the control device 7 assigned to the turnstile 3 grants permission for the passage of the through lane, the brake 17 is released and the drive motor 16 rotates the respective blocking arm 4 from the blocking position into a stopping position in which the motor 16 is stopped again.
  • the turnstile only rotates by a few degrees in order to release the detection beam (FIG. 3).
  • the brake 17 remains released. If the user 18 moves this short way forward, he is, as can be seen from FIG. 4, detected by the detection beam 6, which in turn switches on the motor 16 of the turnstile. The latter rotates the turnstile 3, releasing the passage, until its next blocking arm 4 reaches the blocking position in which the brake 17 is activated again.
  • An exact position of the locking arms 4 in the locking position and in the stopping position is of secondary importance.
  • the blocking position or the stopping position could also be perpendicular to the direction of passage. Of course, intermediate positions are also conceivable.
  • the turnstile is shown without control device 7.
  • Such a turnstile 3 which only knows a blocking position, but no stop position, is often used at the exits of sports facilities to prevent unauthorized access refuse.
  • the turnstile 3 is provided with two opto-electronic sensors 5 in the form of light sensors. Their detection beams 6 extend on both sides of the locking arm 4 located in between. If the user approaches the turnstile from the correct side, the first detection beam 6 first responds to the user, and the turnstile 3 is set in rotation .
  • the motor stops if the second light switch 5 does not respond to the passage of the user in an adjustable time. If, in the given direction of passage, the visitor approaches from the second, ie wrong, side, the second light switch 5 reacts first. Since this is wrong, the motor remains interrupted and the turnstile 3 is locked.
  • the direction of passage can be exchanged in a simple manner, so that the turnstile can be used alternately in both directions.

Abstract

L'invention concerne un tourniquet qui comprend un boîtier (2), un arbre primaire et des bras de blocage (4) en saillie, décalés en angle. Lorsqu'un usager (18) se présente, après vérification de son habilitation à franchir le tourniquet, un moteur d'entraînement se met en marche sans contact pour que le tourniquet passe de la position de blocage d'un bras de blocage (4) à une position d'arrêt suivante se trouvant dans un angle réduit. Afin de faire passer le tourniquet également sans contact dans la position de blocage suivante, un détecteur optoélectronique (5) placé derrière le bras de blocage (4) dans le sens de passage, lorsque ledit bras est en position de blocage, détecte alors le fait que l'usager (18) s'approche du bras de blocage (4) qui se trouve en position d'arrêt.
