Abstract

The invention relates to a torque detection device allowing shutdown of the electrical supply of a tubular gear motor when the preset max torque is reached. For this purpose, the device consists of an elastic element (3) reacting in torsion and arranged between the gear motor (1) and a fastening point (2). The torsional reaction in the event of blocking of the output shaft (5) causes the rotation of the drive ring (4) of the traditional end-of-course device set to detect this simple torsion. The shutdown of the motor occurs no longer after a determined number of revolutions but in the event of blocking during or at the end of operation. This device, which simplifies setting and improves safety of rolling parts is particularly intended for motorising swing wings (door leaves).

Description

DISPOSITIF DE DETECTION DE COUPLE ADAPTE AUX MOTOREDUCTEURS TUBULAIRES MUNIS DE FIN DE COURSE.TORQUE DETECTION DEVICE SUITABLE FOR TUBULAR GEAR MOTORS PROVIDED WITH LIMIT SWITCHES.

La présente invention est relative à un dispositif de détection de couple pour arrêter l'alimentation électrique d'un motoréducteur tubulaire muni de fins de course mécaniques.The present invention relates to a torque detection device for stopping the electrical supply of a tubular gearmotor provided with mechanical limit switches.

Les motoréducteurs tubulaires existants ne possèdent que des dispositifs de fins de course basés sur le dénombrement des tours d'arbre. Un double réglage (position haute et position basse) permet de déterminer le nombre de tours que le motoréducteur doit faire pour monter ou descendre un store, ou un volet roulant.Existing tubular gearmotors only have limit switch devices based on the number of shaft turns. A double adjustment (high position and low position) makes it possible to determine the number of turns that the gearmotor must make to raise or lower a blind, or a rolling shutter.

Ces systèmes excluent toute présence d'obstacles pouvant gêner la manoeuvre. Le moteur ne s'arrête automatiquement que si le nombre de tours assignés est atteint.These systems exclude any presence of obstacles that could hinder the operation. The engine does not stop automatically unless the assigned number of revolutions is reached.

Cette technique peut sembler satisfaisante pour la manoeuvre de roulant, mais n'est pas utilisable pour la manoeuvre des battants.This technique may seem satisfactory for the rolling maneuver, but cannot be used for the flapping maneuver.

En effet, les battants motorisés (volets, portails, etc..) sont soumis à deux contraintes:
- nécessité de s'arrêter en présence d'un obstacle voiture, individu, vent. In fact, motorized leaves (shutters, gates, etc.) are subject to two constraints:
- need to stop in the presence of a car, individual, wind obstacle.

- blocage en pression des battants en position d'ouverture ou de fermeture totales. - pressure locking of the leaves in the fully open or closed position.

La présente invention permet l'adaptation aux battants des motoré- ducteurs du commerce destinés aux roulants en respectant ces deux contraintes.The present invention makes it possible to adapt commercially available gearmotors intended for rollers while respecting these two constraints.

L' avantage est d'élargir considérablement le champ d'application de ces motoréducteurs et d'ameliorer les caractéristiques des opérateurs pour battants qui ont recours à des moteurs et des fins de course/sécurité spécifiques. Par exemple, la sécurité interrompant l'alimentation en cas de blocage ne permet pas le réenclanchement automatique du moteur. Un cycle interrompu { par exemple par le vent f ne se termine pas.The advantage is to considerably widen the field of application of these gearmotors and to improve the characteristics of the operators for leaves which use specific motors and limit switches / safety. For example, the safety device interrupting the supply in the event of a blockage does not allow the motor to be automatically reset. A cycle interrupted {for example by wind f does not end.

Ce même principe, objet de l'invention,peut être également étendu aux roulants évitant ainsi les réglages des points haut et bas et ajoutant la sécurité en cas de blocage accidentel.This same principle, which is the subject of the invention, can also be extended to the rolling wheels, thus avoiding the adjustment of the high and low points and adding security in the event of accidental blocking.

Le dispositif de détection de couple suivant l'invention consiste à placer entre le motoréducteur(1) et son point d'ancrage fixe (2) un élément élastique < 3) capable de réagir à une sollicitation en torsion .La couronne d'entrainement (4) habituellement destinée à compter le nombre de tours est également fixé au même bati (2) que le point d'ancrage fixe du moteur (2). The torque detection device according to the invention consists in placing between the geared motor (1) and its fixed anchor point (2) an elastic element <3) capable of reacting to a torsional stress. The drive crown ( 4) usually intended to count the number of revolutions is also fixed to the same frame (2) as the fixed anchor point of the motor (2).

En cas de blocage (fig.3) de l'arbre de sortie du moteur < 5 > rencontre d'un obstacle ou des positions extrêmes de débattement des battants), l'enveloppe du moteur va réagir en torsion dans le sens inverse de rotation du moteur. Cette réaction en torsion est limitée par l'élément élastique < 3). Pendant ce mouvement, la couronne d'entrainement < 4) aura donc enregistrée une fraction de tour; Le dispositif de réglage des fins de course du moteur étant réglé de tel sorte que cette fraction de tour enregistrée provoquera l'arrêt d'alimentation du moteur.In the event of a blockage (fig. 3) of the motor output shaft <5> encountering an obstacle or extreme leaf travel positions), the motor casing will react in torsion in the opposite direction of rotation of the motor. This torsional reaction is limited by the elastic element <3). During this movement, the drive crown <4) will therefore have recorded a fraction of a turn; The device for adjusting the limit switches of the motor being adjusted so that this recorded fraction of a revolution will cause the supply of the motor to stop.

La valeur de cette fraction de tour peut être adaptée suivant le couple maxi recherché ( dans les limites de la puissance du moteur et de l'amplitude de l'élément élastique sous ce couple > .The value of this fraction of a turn can be adapted according to the maximum torque sought (within the limits of the engine power and the amplitude of the elastic element under this torque>.

En cas de déblocage de l'arbre de sortie (5), l'élément élastique redonne sa position initiale à l'enveloppe du moteur, la couronne d'entrainement repositionnant le dispositif fin de course en position d'alimentation, le moteur redémarre.fig.2)
Quand la position extrême est atteinte, le moteur s'arrête en suivant la même procédure; Son redémarrage est assuré par le déclenchement de la manoeuvre en sens inverse. If the output shaft (5) is released, the elastic element returns its initial position to the motor casing, the drive crown repositioning the limit switch device in the feeding position, the motor restarts. fig. 2)
When the extreme position is reached, the engine stops following the same procedure; It is restarted by triggering the maneuver in the opposite direction.

Suivant la figure 4, la limitation de l'effort de torsion du moteur peut être obtenu en remplacant l'élément élastique par deux ressorts (6) disposés de part et d'autre de l'axe de rotation du moteur; Une extrémité du ressort fixée au moteur (1) l'autre au bati (2), Chacun des ressorts étant affecté à un sens de rotation. According to Figure 4, the limitation of the torsional force of the motor can be obtained by replacing the elastic element by two springs (6) arranged on either side of the axis of rotation of the motor; One end of the spring fixed to the motor (1) the other to the frame (2), each of the springs being assigned to a direction of rotation.
