Description

La présente invention concerne les dispositifs d'actionnement pour portes étanches coulissantes telles qu'on en utilise dans de nombreuses applications et notamment pour équiper des entrepôts frigorifiques.The present invention relates to actuating devices for watertight sliding doors such as are used in many applications and in particular for equipping cold stores.

Ces portes sont en général montées coulissantes sur des rails auxquels elles sont suspendues et qui comportent des encoches déterminant la position de fermeture de la porte. Lorsque les galets de guidage de la porte parviennent dans ces encoches, la porte subit un déplacement vers le bas et en direction du dormant, qui permet de réaliser l'étanchéité. Habituellement le dispositif d'actionnement d'une telle porte est pneumatique, ce qui permet d'obtenir une très grande souplesse de fonctionnement. Cependant, ces dispositifs pneumatiques présentent l'inconvénient d'être relativement coû- taux. On a également utilisé, notamment pour réaliser la phase initiale d'ouverture de la porte, des vérins électriques qui ont pour in- convénient en dehors de leur prix élevé de provoquer une accélération brutale préjudiciable à la bonne tenue de la porte et de son dispositif de suspension.These doors are generally slidably mounted on rails to which they are suspended and which have notches determining the closed position of the door. When the guide rollers of the door reach these notches, the door undergoes a downward movement in the direction of the frame, which makes it possible to produce the seal. Usually the actuating device of such a door is pneumatic, which makes it possible to obtain very great operating flexibility. However, these pneumatic devices have the disadvantage of being relatively costly. Electric cylinders have also been used, in particular for carrying out the initial phase of opening the door, which have the disadvantage, apart from their high price, of causing sudden acceleration detrimental to the good performance of the door and its device. suspension.

En présence d'un tel état de la technique, le but recherché par cette invention consiste à fournir un dispositif d'actionnement plus économique que les dispositifs existants, dont la souplesse de fonctionnement soit satisfaisante et qui offre également toute ga- rantie au niveau de la sécurité d'utilisation.In the presence of such a state of the art, the aim sought by this invention consists in providing an actuation device more economical than existing devices, the flexibility of operation of which is satisfactory and which also offers any guarantee in terms of safety of use.

Ce résultat est obtenu en prévoyant un dispositif d'actionnement pour porte étanche coulissante, caractérisé en ce qu'il comprend d'une part, un premier groupe moto-réducteur agissant dans la phase initiale du déplacement de la porte à partir de sa position de fermeture, par l'intermédiaire d'un dispositif à came et galet et, d'autre part, un deuxième groupe moto-réducteur teur agissant pendant la phase de déplacement à peu près horizontal de la porte par l'intermédiaire d'un limiteur de couple et de moyens de transmission convenables.This result is obtained by providing an actuating device for a sliding watertight door, characterized in that it comprises on the one hand, a first geared motor group acting in the initial phase of the movement of the door from its position of closing, by means of a cam and roller device and, on the other hand, a second gear motor unit acting during the roughly horizontal movement phase of the door by means of a limiter torque and suitable transmission means.

L'invention va être décrite plus en détail ci-dessous en se référant au dessin annexé donné à titre d'exemple et sur lequel :

  • - la Fig. 1 est une vue d'ensemble d'un dispositif d'actionnement suivant l'invention ;
  • - la Fig. 2 est une vue de détail de la came associée au premier groupe moto-réducteur ; et
  • - la Fig. 3 est une vue en coupe montrant le limiteur de couple associé au deuxième groupe moto-réducteur.
The invention will be described in more detail below with reference to the attached drawing given by way of example and in which:
  • - Fig. 1 is an overall view of an actuating device according to the invention;
  • - Fig. 2 is a detailed view of the cam associated with the first geared motor group; and
  • - Fig. 3 is a sectional view showing the torque limiter associated with the second gear motor group.

. On voit sur la Fig. 1 une porte étanche coulissante P qui peut en particulier équiper un entrepôt frigorifique et qui est suspendue à un rail de guidage R. L'ensemble de suspension et de guidage de la porte peut être par exemple tel que décrit et représenté dans le brevet français n°72 42 370 du 29 Novembre 1972 ou dans son Certificat d'Addition n°76 24 558 demandé le 11 Août 1976. Ce dispositif de suspension et de guidage peut également être réalisé de façon différente et ne fait pas à proprement parler partie de cette invention.. We see in Fig. 1 a watertight sliding door P which can in particular be fitted to a cold store and which is suspended from a guide rail R. The assembly for hanging and guiding the door can for example be as described and shown in French patent n 72 72 370 of 29 November 1972 or in its Certificate of Addition 76 24 558 requested on 11 August 1976. This suspension and guidance device can also be produced in a different way and is not strictly speaking part of this invention.

De façon classique, le rail de guidage comporte des encoches non visibles sur le dessin disposées de telle façon que lorsque la porte parvient au voisinage de sa position de fermeture, les galets coopérant avec le rail tombent dans ces encoches, ce qui provoque un déplacement de la porte vers le bas et vers le dormant, ce double déplacement ayant pour effet de réaliser l'étanchéité.Conventionally, the guide rail has notches not visible in the drawing arranged in such a way that when the door reaches the vicinity of its closed position, the rollers cooperating with the rail fall into these notches, which causes the door to move down and towards the frame, this double movement having the effect of achieving sealing .

Le dispositif d'actionnement objet de cette invention comprend principalement un premier groupe moto-réducteur 10 de démarrage qui comporte un moteur électrique 11 et un réducteur 12 de constructions classiques. Le moteur peut présenter par exemple une puissance de 0, 5 CV. et développer un couple de 5, 75 m. daN pour une vitesse de sortie de 50 tours/minute. L'arbre de sortie 13 du réducteur porte une came 14 qui coopère avec un galet 15 porté par la porte, le profil de cette came étant représenté de façon plus détaillée à la Fig. 2. La partie active 16 de cette came s'étend sur un angle de 270° et son profil peut être défini par l'équation en coordonnées polaires y = ax2 + b avec a = 1,65. 10-3 et b = rayon du cercle de base 17 de la came (b = 140mm par exemple), et x en degrés. Ce profil procure un fonctionnement particulièrement souple au démarrage. De préférence l'axe X-X de l'arbre 13 se trouve à un niveau légèrement inférieur à celui de l'axe Y-Y du galet 15.The actuating device object of this invention mainly comprises a first geared motor start-up group 10 which comprises an electric motor 11 and a reducer 12 of conventional constructions. The engine may for example have a power of 0.5 CV. and develop a torque of 5.75 m. daN for an output speed of 50 revolutions / minute. The output shaft 13 of the reduction gear carries a cam 14 which cooperates with a roller 15 carried by the door, the profile of this cam being shown in more detail in FIG. 2. The active part 16 of this cam extends over an angle of 270 ° and its profile can be defined by the equation in polar coordinates y = ax 2 + b with a = 1.65. 10 -3 and b = radius of the base circle 17 of the cam (b = 140mm for example), and x in degrees. This profile provides particularly flexible operation at start-up. Preferably the axis XX of the shaft 13 is at a level slightly lower than that of the axis YY of the roller 15.

Le dispositif d'actionnement est complété par un second groupe moto-réducteur 20 comprenant un moteur électrique 21 et un réducteur 22. Le moteur peut par exemple présenter une puissance de 0,25 CV. et développer un couple de 1,4 m.. daN pour une vitesse de sortie de 100 tours/minute. L'arbre de sortie 23 du réducteur est relié à un pignon à chaîne 24 par l'intermédiaire d'un limiteur de couple 25 comprenant deux flasques 26 portant des garnitures de friction 27 et disposés de part et d'autre du pignon. Une bague 28 en bronze fritté est interposée entre le moyeu 24a du pignon 24 et les parties axiales 26a des flasques 26. On remarquera que le moyeu 24a du pignon est sensiblement plus épais que la denture 24b de ce pignon (de 2 à 4 fois par exemple), de façon à pouvoir résister aux efforts radiaux développés en cours d'utilisation. La pression de serrage des flasques sur le pignon est déterminée par des ressorts 29 interposés entre le flasque adjacent et une plaque 30 fixée sur l'arbre du réducteur par tout moyen convenable. Le nombre et la force des ressorts 29 sont choisis de façon à obtenir un couple limite déterminé qui peut par exemple varier entre 0, 5 et 1 m. daN. Cet agencement permet d'adapter le limiteur en fonction du poids de la porte, par exemple.The actuation device is completed by a second geared motor group 20 comprising an electric motor 21 and a reduction gear 22. The motor can for example have a power of 0.25 CV. and develop a torque of 1.4 m .. daN for an output speed of 100 revolutions / minute. The output shaft 23 of the reduction gear is connected to a chain sprocket 24 by means of a torque limiter 25 comprising two flanges 26 carrying friction linings 27 and arranged on the side and on the other side of the pinion. A ring 28 in sintered bronze is interposed between the hub 24a of the pinion 24 and the axial parts 26 has flanges 26. It will be noted that the hub 24 a of the pinion is substantially thicker than the toothing 24 b of this pinion (from 2 to 4 times for example), so as to be able to resist the radial forces developed during use. The clamping pressure of the flanges on the pinion is determined by springs 29 interposed between the adjacent flange and a plate 30 fixed to the reduction gear shaft by any suitable means. The number and the force of the springs 29 are chosen so as to obtain a determined limit torque which can, for example, vary between 0.5 and 1 m. daN. This arrangement makes it possible to adapt the limiter according to the weight of the door, for example.

Le dispositif de transmission entre ce second groupe moto-réducteur et la porte est ici constitué par une chafne 31 fixée à la porte et passant sur le pignon 24 et sur un pignon de renvoi 32.The transmission device between this second geared motor group and the door is here constituted by a chain 31 fixed to the door and passing over the pinion 24 and over a return pinion 32.

Le dispositif est complété par des moyens de commande, connus en soi qui ne seront donc pas décrits ici.The device is completed by control means, known per se which will therefore not be described here.

Le fonctionnement de cet ensemble est très simple : la porte étant comme sur la Fig. 1 en position de fermeture,pour provoquer son ouverture on alimente tout d'abord le premier groupe moto-réducteur 10 et l'action de la came 14 sur le galet 15 provoque le déplacement de la porte et de ses galets le long des rampes qui délimitent les encoches. On obtient dans cette phase de déplacement une composante dirigée vers le haut du fait de la différence de niveau qui existe entre l'axe X-X de la came et l'axe Y-Y du galet 15. L'alimentation de ce premier groupe est interrompue après un tour de l'arbre de sortie, puisque la partie active de la came ne correspond qu'à 3/4 de tour.The operation of this assembly is very simple: the door being as in FIG. 1 in the closed position, to cause it to open, the first motor-reducing unit 10 is first supplied, and the action of the cam 14 on the roller 15 causes the door and its rollers to move along the ramps which delimit the notches. In this displacement phase, an upwardly directed component is obtained due to the level difference which exists between the axis XX of the cam and the axis YY of the roller 15. The supply of this first group is interrupted after a rotation of the output shaft, since the active part of the cam only corresponds to 3/4 of a revolution.

Ce fonctionnement est donc très bref et consomme très peu d'énergie. De plus la présence de la came 14 et le choix de son profil procurent un fonctionnement particulièrement souple dans cette phase initiale du déplacement.This operation is therefore very brief and consumes very little energy. In addition, the presence of the cam 14 and the choice of its profile provide particularly flexible operation in this initial phase of the movement.

Le second groupe moto-réducteur 20 assure alors la translation horizontale de la porte de façon particulièrement économique puisque cette translation nécessite une puissance relativement faible. La présence du limiteur de couple offre de plus de nombreux avantages :

  • - ce limiteur permet d'obtenir une très grande souplesse lors des inversions de sens de déplacement de la porte ;
  • - il assure la protection du moteur mais aussi du personnel ou du matériel en cas de choc de la porte contre un obstacle ou de coincement d'un objet ou d'une personne entre la porte et le dormant, à la fermeture ;
  • - un avantage tout à fait inattendu réside dans le fait que si un utilisateur est enfermé par mégarde dans l'entrepôt, il lui suffit d'exercer sur la porte un effort relativement faible, correspondant au tarage du limiteur de couple, pour déplacer la porte, contrairement à ce qui se produit dans les agencements connus où il est nécessaire de prévoir des moyens relativement complexes pour permettre ce déplacement,
The second motor-reduction unit 20 then ensures the horizontal translation of the door in a particularly economical way since this translation requires a relatively low power. The presence of the torque limiter also offers many advantages:
  • - This limiter makes it possible to obtain very great flexibility during reversals of the direction of movement of the door;
  • - it ensures the protection of the engine but also of personnel or equipment in the event of a door impact against an obstacle or an object or a person being trapped between the door and the frame, when closing;
  • - a completely unexpected advantage lies in the fact that if a user is inadvertently locked in the warehouse, he only has to exert on the door a relatively low effort, corresponding to the setting of the torque limiter, to move the door , contrary to what occurs in known arrangements where it is necessary to provide relatively complex means to allow this movement,

Ces divers avantages s'ajoutent au fait que la solution adoptée est particulièrement économique puisque de tels groupes moto-réducteurs de relativement faible puissance sont relativement bon marché à l'achat et en utilisation, chacun d'eux étant parfaitement adapté à la fonction qu'il remplit et étant donc utilisé dans des conditions optimales.These various advantages are added to the fact that the solution adopted is particularly economical since such relatively low power motor-reduction units are relatively inexpensive to purchase and use, each of them being perfectly suited to the function that it fills and therefore being used in optimal conditions.
