- the canvas B is preferably still rolled up with one dead turn or several dead turns around the winding tube 5.
- the deployed and visible canvas 3 is not the part of the canvas directly in contact with the roller tube 5, which could be more marked by the surface imperfections of the roller tube 5 or by the line of junction between the fabric 3 and the roller tube 5.
- the fact of providing one or more dead turns in the calculation of the size of the fabric before its installation makes it possible not to show the winding tube 5 bare, unsightly, when the fabric 3 is in its low position PI.
- the method for adjusting the installation 1 makes it possible to control the movement of the load bar 7 of the canvas 3 into a single position P3, the so-called canvas replacement position, which it is necessary to 'achieve when the user wishes to replace the canvas 3 (and the load bar 7) with another canvas (and another load bar).
- the canvas replacement position P3 is located beyond the position P2 in the direction of unwinding of the canvas 3, that is to say it is located lower than the position P2.
- the canvas replacement position P3 corresponds to a position in which the canvas 3 is completely unrolled, without dead turn, unlike the low position P2 where one seeks to preserve the presence of the dead turn or turns on the tube winding 5.
- the difference between the positions P2 and P3 is therefore equal to the length of fabric 3 rolled up on the winding tube 5 used to make the dead turn(s).
- the method according to the invention comprises a step in which the means for locating the position of the windable element locates the unique position P3 of replacement of the canvas 3, whereby the canvas 3 is completely unrolled with respect to the winding tube 5.
- the adjustment method according to the invention can be implemented for example by an operator in the factory, when setting up the installation 1.
- an operator detects manually, for example visually, the replacement position P3 of the fabric 3, in which the fabric 3 is completely unrolled relative to the winding tube 5 by varying the position of the screen up to this position P3.
- the locating means locates the successive positions taken by the screen and the position P3 indicated by the installer.
- the electronic control unit is equipped with a memory means, allowing the storage of the replacement position P3 of the identified fabric 3, so that this position can be recalled later by a user when the fabric must be changed.
- the method according to the invention can be initiated via the control interface 11.
- the control interface 11 comprises for example two keys which allow a user to respectively control a movement of the fabric 3 in its winding direction or in its unwinding direction.
- a combination of keys or a specific key also makes it possible to move the motorized screen to its canvas replacement position P3 and to locate the latter.
- the tracking can also take place in the absence of movement for a predefined period during a step of searching for the canvas replacement position.
- the control interface 11 is a mobile terminal, a previously installed control application controls the triggering of the adjustment method of the invention.
- the command interface 11 sends a corresponding command to the operating actuator, which will move the fabric 3 so as to locate the fabric replacement position P3.
- the parameter analyzed can be, according to a first variant, the parameter representative of the position, in particular the position taken by a free end of the fabric 3 or, according to a second variant, the parameter representative of the torque provided by the engine.
- the electric motor of the canvas maneuvering actuator 3 is driven in rotation in its first direction of rotation, according to which the canvas 3 is moved in a position of conventional operation in the direction of unwinding D, towards the bottom of the installation (phase A represented in FIG. 4).
- the variations in torque of the electric motor are analyzed, in particular by monitoring the variations in current when the electric motor is of the direct current and brush and collector or direct current and electronically commutated type, or by monitoring voltage variations when the electric motor is an asynchronous motor.
- the unwinding of the canvas 3 is continued by continuing to rotate the motor in its first direction of rotation.
- the load bar 7 of the fabric 3 exceeds the low position P2 until the fabric 3 is completely unrolled, that is to say that the dead turn(s) are completely unrolled.
- the unwinding of the canvas 3 relative to the winding tube 5 modifies on the last dead turn the position of the junction between the canvas 3 and the winding tube 5, relative to the axis 17 of the winding tube 5 In the position illustrated in phase B of figure 4, the fabric 3 is completely unrolled and aligned with the axis 17 of the roller tube 5.
- This position corresponds to the canvas replacement position P3 to be reached.
- the torque that the electric motor must supply is minimal.
- the electronic control unit 9 determines, from the torque analysis which has just been carried out, the minimum value of the torque, representative of the fabric replacement position P3.
- This value is identifiable when the torque monitoring means of the electronic control unit 9 detects, during the step in which the electric motor is rotated in its first direction of rotation, a reduction in the torque of the motor followed by an increase in torque. In particular, this value is identifiable when it is observed over a range of positions situated beyond the low position in the direction of unwinding.
- step E10 the position of the windable element when the minimum torque value is reached is identified, said value being representative of a windable element replacement position.
- step E4 the electric motor is driven in rotation until the minimum torque value identified during step E10 is reached.
- the identification of the canvas replacement position P3 can occur during the displacement of the canvas, the position being able to be exceeded.
- the electric motor is initially driven in rotation in its second direction of rotation, in which the fabric 3 is moved in the conventional operating situation in the winding direction E.
- the fabric 3 being rolled up, in part, on the winding tube 5 in the opposite direction after having passed the position P3, the fabric 3 begins an unwinding phase.
- the electronic control unit 9 monitors the torque supplied by the electric motor during the unwinding phase of step E4, corresponding to rotation of the motor in its second direction of rotation. This monitoring can make it possible to refine the identification of the minimum torque position. Alternatively or in addition, the electronic control unit monitors the position of the windable element.
- step E5 when the canvas 3 reaches the canvas replacement position P3 following the unwinding phase of step E4, the electronic control unit 9 stops the rotation of the electric motor, in the canvas replacement position P3 .
- the stoppage in position P3 for replacement of fabric can be carried out after one or more iterations of movement between the bottom end-of-travel positions reached by a downward movement and the bottom end-of-travel position reached by an upward movement. Multiple iterations during step E4 make it possible to refine the position of minimum torque and thus to present the most appropriate position to the user who wishes to change his fabric.
- the adjustment method which has just been described applies when the monitored parameter is representative of the position of the fabric 3 instead of the torque.
- the electronic control unit 9 determines the minimum value taken by the free end of the fabric 3, that is to say the lowest position reached in the direction of the unwinding of the fabric 3. This step is carried out consecutively to step E2 at the end of which the method has analyzed the variations in the positions taken by the fabric 3, in particular the positions taken by the free end of the fabric 3.
- the lowest position reached by the canvas is obtained for example when an optical sensor has detected that the canvas 3 is no longer rolled up at least in part on the winding tube 5, that is to say when the optical sensor is pointing at the tube of bare winding, or through an analysis of the direction of movement of an accelerometer mounted on or in the load bar.
- the load bar 7 rests against this rim when the position low P2 is reached or at least slightly exceeded in the direction of unwinding.
- the load bar 7 comes into abutment against the rim and the electric motor continues its rotation in its first direction of rotation, the load bar 7 is then no longer suspended relative to the winding tube 5: the torque that must be provided by the electric motor or the position of the free end of the canvas no longer changes significantly until the load bar is again shifted from this edge.
- the range of positions corresponding to the minimum torque or to the lowest position is then greater than in the case where the canvas 3 and the load bar 7 are suspended from the winding tube 5.
- the adjustment method according to the invention comprises a step aimed at identifying the moment from which the load bar 7 lands on the obstacle, and the moment from which the load bar 7 is lifted from the obstacle.
- the electronic control unit 9 thus monitors the position of the windable element in order to estimate the positions in which the load bar 7 will land on the obstacle, and in which the load bar 7 is again raised from the obstacle.
- the installation 1 of the invention is equipped with an angular position encoder and/or a time counter, used to identify these positions.
- the angular position encoder and/or the time counter can form part of the position tracking means or be complementary thereto.
- the adjustment method of the invention comprises a step aimed at counting the number of pulses generated by the electric motor between a first position in which the load bar 7 lands on the obstacle and a second position in which the load bar load 7 is lifted from the obstacle.
- the step aimed at determining the fabric replacement position P3 is then obtained by dividing by two the number of pulses counted.
- the fabric replacement position P3 corresponds to a position halfway between the first position and the second position.
- the method comprises an additional step proposing to the user, after the rotation of the electric motor has been stopped, to slightly modify the position of the fabric with respect to the position P3 of replacement of fabric reached automatically during the implementation of the method.
- This step allows the user to adapt the positioning of the canvas according to certain usage constraints, which are in particular:
- the possible range of movement can be limited in order to avoid damage to the canvas due to the fact that the stops in the low position P2 and in the canvas replacement position P3 are not temporarily more taken into account.
- the electronic control unit 9 controlling the electric motor of the winding tube 5 is configured to stop the rotation of the electric motor when it has performed a predetermined number of revolutions.
- This number of turns may be less than one. This number of turns can be representative of a distance depending on the distance between the low position P2 and the fabric replacement position P3.
- this distance can be equal to twice the distance between the low position P2 and the position P3 of determined fabric replacement.
- the adjustment method of the invention can be implemented when installing the installation 1, for example when the installer performs the learning of the high PI and low P2 positions.
- the installer can proceed at that time to locate the fabric replacement position P3 by the method of the invention, without necessarily needing to stop in this position.
- the location step E10 can then include a step of storing in the installation the fabric replacement position P3.
- the electronic control unit comprises a memory suitable for this purpose.
- This fabric replacement position P3 is then simply recalled at will by the user.
- the user uses the command interface 11 to issue a movement command to the stored fabric replacement position P3.
- the control interface 11 can include for this purpose a specific fabric replacement key, or else a combination of keys of the control interface 11 can be carried out to place the fabric 3 in the previously recorded fabric replacement position P3 during the implementation of the method of the invention.
- the adjustment method can be implemented directly at the moment when it is desired to replace the fabric 3.
- the steps E4 and E5 are also implemented and it is not obligatory to store the canvas replacement position P3 marked.
