Definitions

  • An actuator of this type is, for example, described in US 4887205 in which the pinion associated with the output shaft of the engine is coupled to a series of gears for reducing the rotation speed of the engine; in particular, then, the last gear engages the links of a chain which is integral with the barrier to be moved.
  • torque motors are also known, that are engines of particular conception which develop a high torque at low rotation speed and which, thanks to these characteristics, would be directly usable in all those applications requiring this type of performance.
  • Another object of the invention is to propose a more compact actuator apparatus.
  • Another object of the invention is to propose an actuator apparatus for actuating a sliding barrier which ensures a mechanical locking of the barrier in any intermediate position between its extreme positions.
  • Another object of the invention is to propose an actuator which is perfectly in line with the safety requirements imposed by the sector legislation.
  • Another object of the invention is to propose an actuator that improves and/or is alternative to traditional ones.
  • Another object of the invention is to propose an actuator apparatus that is simple, quick and inexpensive to install.
  • the actuator apparatus 1 for a sliding barrier comprises an electric motor which is a torque motor 2 configured to cause the rotation of its output motor shaft 10.
  • the torque motor 2 is brushless and synchronous.
  • the maximum rotation speed of the torque motor 2 under normal operating conditions is not higher than 600 revolutions per minute.
  • a pinion 14 is fitted together with the shaft 10, or preferably they are made of a single body, intended to be coupled with a linear gear, preferably a rack 16 (but it could also be a chain), which is applied to the sliding barrier to be moved, not represented.
  • the output of the motor shaft 10 of the motor 2 is provided with a pinion 14 which directly engages - that is, without the interposition of a transmission unit, a gear or other gears - the linear gear 16, preferably a rack, which is integral with the sliding barrier to be moved.
  • the pinion 14 has a number of teeth comprised between eight and seventeen.
  • the pinion 14 has a number of teeth not greater than seventeen, preferably not more than twelve and even more preferably not more than eight.
  • the actuator apparatus 1 also comprises a locking device comprising:
  • the engagement member 26 is mounted on the housing of the torque motor 2.
  • the locking member 22 is mounted on the shaft 10 of said torque motor 2.
  • said locking member 22 comprises a toothed wheel 22 which is mounted in neutral on the shaft 10 of the torque motor 2.
  • said damping mechanism comprises at least one body 18 or 19 which is integral in rotation with the output shaft 10 and which is kept in contact with the locking member 22.
  • the actuator apparatus 1 comprises a further locking member 19 integral with rotation to the output shaft 10 of the torque motor 2 and associated with a further engagement member 25 which is moved by a further electromagnetic actuator 27 which can be operated between one engagement condition of said further locking member 19, when said motor 2 is stationary, and a condition for disengaging said additional locking member 19 when said motor 2 is supplied.
  • the switching of said further electromagnetic actuator 27, being controlled by said control and command unit coincides with the passage of motor 2 from the condition supplied to the unpowered condition and vice versa.
  • said further locking member 19 is constituted by a body of said damping mechanism which is integral in rotation with the output shaft 10 and which is kept in contact with the first locking member 22.
  • said bodies of the damping mechanism comprise an annular jaw 18 and a further toothed wheel 19 which, preferably, acts as a jaw.
  • the annular jaw 18 is coupled to the shaft 10 which is configured to be integral in rotation with the shaft itself and also to perform reciprocal movements parallel to the longitudinal direction of development of the rotation axis of the shaft 10.
  • said further (second) toothed wheel 19 is fitted together with the shaft 10.
  • the first toothed wheel 22 which defines said locking member
  • both the jaw 18 and the further toothed wheel 19 are associated, on the side facing the first toothed wheel 22, with friction rings 20, 20'.
  • the first bolt 26 is associated with a second monostable electromagnet 23; preferably, for this purpose, a spring 28 is provided, which tends to keep said second bolt in the engagement position of the second toothed wheel 22, from which it is removed when its electromagnet 23 is energized by the same supply current of the torque motor 2.
  • both the bolts 25, 26 are provided with a single space engagement tooth delimited by two successive teeth of the respective toothed wheel 19, 22, but an analogous result could also be obtained with two bolts 25', 26' (see Fig. 8 ), having several teeth simultaneously engaged between several spaces delimited by several successive teeth of the two toothed wheels 19, 22 respectively; on the contrary, advantageously, in this case the engagement between bolts and toothed wheels could be easier, safer and more immediate.
  • a gear chain can be associated to the output shaft 10 of the torque motor 2, indicated as a whole with the reference 29, with a revolving gear reduction effect.
  • the operation of the actuator apparatus 1 according to the invention is as follows: in normal operating conditions, when the barrier is closed, the second electromagnet 27 maintains the second bolt 25 engaged with the second toothed wheel 19 and the first electromagnet 23, which is not powered, allows the elastic element (preferably spring-loaded) 28 to maintain the first bolt 26 engaged with the second toothed wheel 22.
  • the overall result is that the two bolts 25, 26 keep the motor 2 blocked, preventing the actuation of the barrier by direct manual thrust on it.
  • the power supply of the motor 2 causes the rotation of its pinion 14 which, by engaging directly with the linear gear 16 (preferably a rack), causes the opening movement of the barrier.
  • the magnet 50 of the shaft 10 determines and also controls the rotation of the magnetic field, which causes rotation of the torque motor 2.
  • the second bolt 25 would remain disengaged from the second toothed wheel 19 while the first bolt 26 would be immediately activated while the barrier continues to move forward due to inertia, with the risk of damaging the first bolt 26 and/or the first toothed wheel 22, from this engaged.
  • the damping coupling, and suitably frictioned, between the shaft 10 of the motor 2 and the first toothed wheel 22, which allows the shaft 10, which is mechanically coupled directly with the linear gear 16 (preferably rack), to continue its rotation by the inertia of the whole moving part, even if the first toothed wheel 22 is locked.
  • Another advantage of the invention consists in the possibility of having a secure mechanical locking of the barrier at both ends as well as in any desired intermediate position.
