Definitions

  • the invention relates to a turnstile, the shaft of which can be locked against rotation in one direction by means of a controllable locking device.
  • Turnstiles of the most diverse types are known, in which a plurality of locking arm holders with these associated locking arms or locking brackets are connected in a rotationally secure manner at the same angular intervals to a shaft of the turnstile which extends perpendicularly or approximately 45 ° downwards. So that the turnstile only allows the passage in one direction, they are equipped with controllable locking devices that have an electromechanical or electromagnetic actuation device and, if necessary, can also be completely deactivated, so that in the event of a catastrophe or the like, the passage provided with the turnstile in both Directions and can be passed without hindrance to people passing through. In the case of an inclined shaft of the turnstile, additional locking devices are used to release the passage, which To release the passage, unlock the locking arm in the locked position so that it can fold down into the vertical position.
  • the person passing through When passing the passage blocked by the turnstile, the person passing through must press the arm or bracket in the locked position in the passage direction by pressing against the locking arm or the locking bracket, whereby a spring force has to be overcome which the respective locking arm or locking bracket in the existing Attempt to keep locked position.
  • This restoring force remains approximately up to half of the necessary angular path between successive locking positions of the turnstile. If half of the angular path is exceeded, the turnstile is accelerated in its movement in the direction of the next blocking position by the action of the spring force and is held in the next blocking position by interaction with detents.
  • an electrically controlled, hydraulically operated turnstile which can be rotated in two directions, but selects a preferred direction at a specific point in time due to a controllable locking device.
  • the turnstile In other turnstiles without spring forces acting on them and without any provided locking positions in the locking position, the turnstile must be equipped with so much locking arms or locking brackets arranged radially on the circumference of the shaft that after a relatively short angular path of the arm or bracket moved out of the locking position through the subsequent passage or arm blocked the passage again becomes. As a result, the freedom of movement of the person passing through the passage in the area of the turnstile is extremely restricted.
  • the invention has for its object to design a turnstile of the type mentioned in such a way that a largely uniform angular movement of the turnstile from one locked position to the next and a secure transfer of the turnstile into the following locked position is guaranteed.
  • the aforementioned formation of the turnstile achieves an intermittent drive of the turnstile, which can be triggered in the simplest manner by a movement impulse in the respective passage direction onto the cross located in the blocking position and the electrical switch which can be actuated in the process.
  • the end of the turnstile movement when the next locking position is reached can also be effected by the switch mentioned.
  • the electrically actuated braking device acting on the motor shaft ensures that the turnstile is reliably stopped in the next following locking position and prevents overrun when the electric motor drive is switched off.
  • the braking device can be designed as an electromagnetic braking device, or else as an electric eddy current brake. If the braking device can be actuated electromagnetically, depending on the switching of the electromagnets, the braking effect can either when the magnets are energized or de-energized, where appropriate additional compression springs can be provided which counteract the electromagnetic forces. Depending on the circuit of the braking device, the circuit of the braking device is opened or closed by the above-mentioned electrical switch which can be actuated by the movement pulse on the cross located in the blocking direction.
  • the electric motor drive of the turnstile can consist of an electric gear motor, or also of a gear separate from the electric motor.
  • turnstiles are known per se, for example from US-A-22 04 897. However, this turnstile can only be rotated in one direction in order to be able to fulfill its task at all. It is a device that blocks a person's passage until they have taken a ticket offered by the machine. Such a device can inevitably only be designed to control a direction of passage.
  • the motor is also connected to a self-locking gear.
  • the braking device can be structurally combined with the electric motor, or else act on the shaft of the electric motor as a brake separate from the electric motor.
  • the circuits for the drive motor can be switched on and / or off via additional switching devices which are actuated by the electrical switch which can be actuated by the movement pulse in the blocking position of the cross.
  • the switch which can be actuated by a movement pulse in the direction of passage onto the cross located in the blocking position is arranged in the region of the turnstile shaft and switch cams which cooperate with this and which rotate with the turnstile shaft are provided. If adjustable switch cams are used, the turnstile can be locked precisely.
  • the switch which can be actuated by the switching cams can serve as an on and off switch both for the circuit of the drive motor and for the braking device.
  • the braking device can only be temporarily actuated and then released when the turnstile is moved into the respective locking position, for example by means of a timing relay, without the risk of the turnstile being pivoted out of the locking position. In this case, it is only necessary to actuate the braking device shortly before reaching the respective blocking position via the electrical switch which can be actuated by a movement impulse of the cross, while the braking device remains in the open position for the rest of the time.
  • the switch which can be actuated by the rotating switching cams can either be designed as a mechanically actuated switch or else as a contactless switch.
  • the movement sequence of the turnstile can be triggered by the fact that a contactless additional electrical switch that can be actuated by approaching the turnstile in the respective direction of passage in parallel with the electrical switch actuated by the movement impulse on the turnstile.
  • the additional electrical switch which can be actuated by approaching the turnstile can be, for example, a switch operating in the manner of a light barrier or else a switch which can be actuated by infrared sensors. With the arrangement described, this switch starts the drive of the turnstile from the respective locked position, while the shutdown takes place via the electrical switch actuated by the movement impulse.
  • a non-contact switch that can be actuated by approaching the turnstile in the respective passage direction or an additional switch that is arranged in the respective passage direction in front of the turnstile with a mechanical or electronic switch that can be actuated in particular by a magnetic card Opening the circuit for the braking device is provided.
  • the electronic lock can be connected to a data processing system, so that it can be determined by corresponding data on the magnetic card when and who has passed the turnstile. If the aforementioned mechanical or electronic lock is arranged both in front of and behind the turnstile, a corresponding check is possible in both directions of passage, and the mechanical or electronic lock can also be used to switch the locking device for the turnstile at the same time, so that it is in the respective one Direction of passage is rotatable and is blocked in the opposite direction.
  • a particularly expedient embodiment is achieved if at least the switch which can be actuated by movement impulse on the turnstile is connected to a frequency converter which is in the circuit of the Drive motor is arranged.
  • the entire sequence of movements of the locking cross can be controlled and adapted to the respective conditions via the frequency converter, for example to take account of the geometry of the turnstile with the axis of rotation inclined to the ground. It is particularly favorable if the circuit of the braking device is also connected to the frequency converter, so that the braking device can be precisely controlled via the frequency converter.
  • the frequency converter can be switched on by additional switches which can be actuated by approaching the turnstile or connected to a mechanical or electronic lock, after the program execution of which the movement of the turnstile is then controlled before reaching the next locked position
  • the frequency converter is switched off via the switch that can be actuated by a movement impulse on the turnstile.
  • the drawing shows a schematic representation of an embodiment of the invention.
  • the drawing shows a partial longitudinal section through a drive housing of a turnstile, the locking arms of which are not shown in the drawing are connected in a rotationally secure manner at the same angular intervals to a shaft which is inclined downward by approximately 45 °.
  • the drawing shows an electric motor 1 which can be driven at the turnstile and which is equipped or coupled with a shaft-mounted, electrically actuable braking device 2, so that the motor 1 and the braking device 2 are enclosed by a common housing.
  • the motor 1 is a drive motor formed, that is, the gearbox, which is denoted overall by 6, is integrally connected to it.
  • the output shaft of the transmission 6 functionally forms part of the turnstile shaft 8, so that it was also designated 8 in the drawing.
  • the turnstile shaft 8 is held on the front wall 16 of the housing by means of a flange stop 18.
  • a torque support 14 is also connected to the transmission, through which a bolt 13 extends, which is firmly connected, preferably welded, to the front wall 16 of the housing via a gusset plate 12.
  • the reversing locking device cooperating with the turnstile shaft 8, which enables the rotation of the locking cross in only one direction and locks in the other direction, is not shown in the drawing, since it is not the subject of the invention.
  • the device for locking the individual locking arms and for unlocking the respective arm in the locking position for completely releasing the passage by folding down this locking arm is not shown in the figure, since this device is also not the subject of the invention.
  • the turnstile shaft 8 is connected in a rotationally secure manner to a switching disk 4 at its end facing the rear wall 16a of the housing.
  • the switching disk is enclosed by a retaining ring 3 which is firmly connected to the housing of the transmission.
  • switching cams 5 On the switching disc 4 towering switching cams 5 are arranged, their number and distribution around the drive shaft 8 of the turnstile corresponds to the arrangement of the locking arms not shown in the drawing on the drive shaft 8 of the turnstile.
  • the switching cams 5 can be designed for adjustment as eccentric cams rotatable about an axis.
  • the switching cams 5 cooperate with an electrical switch 10, which is arranged in a stationary manner on the fastening ring 3 by means of a retaining ring 9.
  • the electrical switch 10 is provided so that it opens and / or closes the circuit for the drive motor 1 and the braking device 2 directly or indirectly by a movement pulse in the respective direction of passage onto the turnstile located in the blocking position.
  • the cross lock In the position shown, the cross lock is in the locked position.
  • One of the switching cams 5 is in alignment with the electrical switch 10, so that it keeps the circuit of the electric motor 10 open in the said position and also the circuit for the electrically actuated braking device 2.
  • the turnstile shaft 8 is pivoted in the direction of arrow 21 by a few angular degrees, so that the switching cam in alignment with the electric switch 10 is disengaged from the electric switch 10 and thereby in the aforementioned electric Circuit arrangement of the circuit for the electric drive motor 1 closed, while the circuit for the electrically actuated braking device remains open and thus the braking device does not act on the shaft of the electric motor 1.
  • the turnstile shaft 8 is thus pivoted further in the direction of arrow 21 by the motor actuation until the next switching cam 5 comes into an aligned position with the electrical switch 10. This happens immediately before the next locking arm reaches its locked position. Due to the action of the switching cam 5 on the electrical switch 10, the circuit for the electric motor 1 is opened and, at the same time, the circuit for the electrically actuable braking device 2 is temporarily closed, so that the locking cross is stopped when the locking position is reached. The electrical braking device 2 can be opened again via a time relay.
  • additional switches 22, 23 can be arranged, for example, on both sides of the turnstile shaft 8 in the front wall 16 of the housing.
  • these additional switches 22 and 23 are designed as switches which can be actuated by magnetic cards and are arranged behind corresponding slots 24 and 25 in the front wall 16.
  • the switches 22 and 23 can serve on the one hand to reverse the locking device for the turnstile and at the same time be provided for opening the circuit for the braking device 2. It can be registered by electronic scanning of the magnetic cards and connection of the switches 22 and 23 with a data recording device when and who has passed the passage equipped with the cross in which direction.
  • the additional switches 22 and 23 can also be designed as simple non-contact switches be, which effect the reversal of the locking device for the turnstile and are also arranged parallel to the electrical switching device 10, so that by this switch when a person approaches the turnstile the circuit for the electric motor 1 is closed and thus the turnstile until the next one is reached Locked position is driven. The turnstile is again stopped in the manner already described by means of the electrical switch 10 by interaction with the next switching cam 5.
  • a frequency converter 11 can be arranged in the housing, to which the circuit of the drive motor 1 and preferably also the circuit of the braking device 2 is connected.
  • the circuit 10 of the drive motor 1 and the braking device 2 are connected to the supplying network via the switches 10 described and any additional switches 22 and 23 which may be provided via the frequency converter 11.
  • the speed of movement of the locking cross and the actuation of the electric brake 2 can be controlled very sensitively and within very wide limits.
  • the direction of rotation of the motor can also be reversed, for example via the additional switches 22 and 23. It also enables extensive electrical braking of the electric motor 1, so that the braking device 2 practically only has to be designed as a short-term holding brake.
