Definitions

  • the invention relates to the field of installations of motorized rolling elements. It relates more particularly to a method for automated adjustment of an installation comprising a motorized screen, or motorized rolling shutter, configured to be moved between a lower position and an upper position, the motorized screen comprising an apron provided with a free end or lower slat, the installation being provided with a blocking or anchoring mechanism, cooperating with the lower slat, to block the movement of the latter during movement towards the upper position.
  • Screen installations or known motorized roll-up elements generally comprise a screen, such as an apron formed of articulated and stackable blades, or else an assembly comprising a canvas and a weighted load bar, the apron being rollable around 'a winding tube located in the upper part of the installation, thanks to motorized drive means or actuator.
  • the final slat, or lower slat located at the lower free end of the apron or canvas load bar is guided by rails located on either side of an opening to be masked. This lower slat can be moved between a lower extreme position, for example in contact with a threshold of the opening and an upper extreme position, for example at the level of a box in which the screen is rolled up.
  • These installations may also include blocking mechanisms, such as locking means making it possible to maintain the lower slat or the load bar of the screen in a determined position while preventing it from being lifted by breaking or slamming under the actions of the wind.
  • blocking mechanisms such as locking means making it possible to maintain the lower slat or the load bar of the screen in a determined position while preventing it from being lifted by breaking or slamming under the actions of the wind.
  • Such installations are used in particular for shutters offering a secure ventilation position, the slats being spaced apart from each other and being spaced apart from the threshold of the opening.
  • Other blocking mechanisms allow orientation of adjustable slats of a roller shutter, as described in the application EP2226462 or even a projection of the deck in a secant plane to their main unwinding plane, as described in the requests FR2962759 , EP2783063 Where FR2941996 .
  • the blocking mechanisms of such installations are configured so that when moving the motorized screen in a first direction, for example during unwinding, the final slat of the screen, that is to say the slat bottom of the hinged slatted shutter or the load bar of a fabric, enters the blocking mechanism, then, following a reverse movement, in a second direction, blocks in the blocking mechanism.
  • An actuator is generally placed in the winding tube and responds to commands emanating from a user via a control interface such as a remote control or a wall interface.
  • the actuator comprises a motor and a reduction gear as well as an electronic control unit comprising electric or electronic means for managing the movement of the motorized screen according to the orders received and according to events detected.
  • These electrical or electronic means may, to do this, comprise position, torque or travel time detectors or sensors.
  • a first position corresponds to the upper end of travel of the motorized screen
  • a second position corresponds to the so-called locking position
  • a third position corresponds to the position in which the movement of the motorized screen must be reversed so as to activate the locking means
  • a fourth position corresponds to the so-called unlocking position below which it is necessary to move to unlock the motorized screen.
  • the installer proceeds to the recording of the value of an angular position of the winding tube chosen, called recorded position of inversion of rotation. This position is located, in the unwinding direction of the motorized screen, at or beyond the third position (rotation inversion position).
  • the user must place the blade bottom of the shutter or the load bar of the fabric in an area identified by markings on the guide rails or the locking means.
  • the object of the invention is to remedy these drawbacks by proposing a method for adjusting an installation of a motorized screen according to claim 1.
  • an entry position in the locking mechanism is automatically determined which can be used as an inversion position. of rotation candidate for automatic learning of the rotation reversal position. This prevents the user from having to place the lower slat of the shutter or the load bar of the canvas in an area marked by markings on the guide rails or the blocking mechanism.
  • the steps of analyzing the variations of the parameter and of determining the input position are implemented by the actuator.
  • the entry position into the blocking mechanism is obtained from the determination of a reference position, the reference position being associated with the detection of a local maximum value of the parameter or with the detection of a local maximum variation value of the parameter.
  • the adjustment method can be carried out entirely automatically, without the intervention of an installer or a user to define the reference position associated with the locking mechanism.
  • the entry position in the blocking mechanism is obtained by an offset of a predetermined value from the position of reference.
  • This offset can in particular be linked to geometric considerations of the blocking mechanism or of its location in the installation.
  • the entry position of the blocking mechanism can be defined from the reference position identified automatically.
  • the parameter is the torque exerted by the actuator moving the deck in the second direction of movement.
  • the torque is in fact a parameter whose variations can be detected reliably and simply.
  • the torque is determined from a measurement of the current flowing through an electric motor of the actuator.
  • the direction inversion position recorded be sufficiently far from the stop position in the blocking mechanism to prevent the lower slat of the shutter from being prematurely in abutment in the blocking mechanism while the actuator is in operation, the torque detection not yet being active or operational, and to prevent the actuator from thus exerting significant forces on the locking mechanism which could damage it.
  • the locking mechanism in fact comprises flexible or mobile parts which are fragile if they are subjected to significant and/or repeated mechanical stresses.
  • the joints connecting the slats of the apron can relax. Therefore, if the direction inversion position recorded by the user is too close to the exit position of the locking mechanism, part or all of the lower blade could end up coming out of the locking mechanism. It is therefore also desirable to ensure that the inversion position direction is chosen so that it is sufficiently far from the release position of the locking mechanism.
  • the installation position and/or the dimensions of the blocking mechanism may vary and the activation times of the torque detections may also differ from one actuator to another. It is therefore necessary to be able to fine-tune the settings for each installation.
  • each candidate rotation reversal position is recorded in a memory of a control unit of the motorized screen installation.
  • the distances between the candidate rotation reversal positions and the blocked position are stored in memory. These distances can be respectively associated with the blocked position and with these candidate rotation inversion positions. It is thus possible, on the basis of these stored data, to easily determine an optimum rotation reversal position.
  • each candidate rotation inversion position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate rotation reversal position.
  • the interruption of the iteration of the sequence a)-b) is decided by detection of an absence of obstacle during the winding of the motorized screen at the level of the locked position or for a predetermined time from the start of the winding.
  • the angular position value of the winding tube corresponding to the locked position is determined using a detector or position sensor of the winding tube or using a time counter.
  • the locked position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the locked position.
  • the angular position value of the winding tube corresponding to the output position is measured using a driving torque sensor of the apron.

  • the installation further comprises a device for activating a displacement function of the controlled apron by an activation element intended to be actuated by a user, for example an activation button, in which the actuation of the activation element also allows the triggering of the steps of analysis of the variations of the parameter and of determination of the entry position in the blocking mechanism.

  • the sequence a), b) is then repeated until the free end of the apron 2, namely the lower slat 5 of the apron 2, passes the exit position P4, beyond which the locking of the motorized screen 1 is no longer activated when motorized screen 1 is driven in the winding direction.
  • the apron 2 is driven in the unwinding direction to a third candidate rotation reversal position PM3 located beyond the first rotation reversal position PM1 in the unwinding direction of the apron 2.
  • the third position d candidate rotation inversion PM3 is located at a distance d from the previous candidate reversal position PM2, that is to say at a distance 2d from the first candidate reversal position PM1.
  • step b) is also reproduced: the winding of the apron 2 is carried out until the lower blade 5 finds itself in the position P2 .
  • step 110 the iteration of the sequence a)-b) continues.
  • the decision to interrupt the sequence a)-b) can be taken after a predetermined time has elapsed from the start of the winding.
  • the interruption of the iteration sequence a)-b) after one or more iterations makes it possible to validate the configuration of the device.
  • the angular position value D4 of the winding tube corresponding to the position P4 is then automatically defined from the last rotation reversal position, in the example above the position PM4 before the interruption of the sequence a )-b).
  • the value of the optimal position retained is used in the mode of use of the motorized screen installation 1. Indeed, when the user sends to the motorized screen installation 1, in the open position, an order to positioning in secure ventilation, the motorized screen installation 1 first performs a rotation action of the winding tube 4 in the direction of the unwinding of the apron 2. Then, when the position sensor 10 detects that the tube winding 4 has reached the optimum position corresponding to the fact that the lower slat 5 is in the optimum position, the motorized screen installation 1 performs an action of stopping the rotational movement of the winding tube 4.
  • the installation motorized screen 1 then immediately executes an action of rotation of the winding tube 4 in the winding direction until position D2 is reached, meaning that the lower slat 5 is locked in position P2 and therefore that the apron reached nt the requested safe ventilation position.
