Description

La présente invention concerne une commande à distance utilisable en particulier pour des moteurs électriques antidéflagrants.The present invention relates to a remote control which can be used in particular for explosion-proof electric motors.

Dans certaines applications, par exemple pour la commande d'agitateurs de peinture ou d'autres produits contenant des composants volatils, on utilise des moteurs antidéflagrants qui sont souvent placés à des endroits peu accessibles. Il est donc important de pouvoir commander ces moteurs électriques à distance.In certain applications, for example for controlling paint stirrers or other products containing volatile components, explosion-proof motors are used which are often placed in inaccessible places. It is therefore important to be able to control these electric motors remotely.

Par ailleurs, dans l'utilisation considérée, un mélangeur ou un autre appareil doit être entraîné pendant un laps de temps bien déterminé, de sorte que la commande doit être munie d'une minuterie pour éviter de devoir la surveiller en permanence. Il est très important également que le moteur puisse être arrêté immédiatement s'il survient un incident et il est connu dans la technique qu'une intervention particulièrement rapide est obtenue lorsqu'on dispose d'un interrupteur ou bouton d'arrêt fonctionnant par enfoncement puisqu'un actionnement dit en coup de poing correspond à un réflexe automatique.Furthermore, in the use under consideration, a mixer or another device must be driven for a well-defined period of time, so that the control must be provided with a timer to avoid having to monitor it constantly. It is also very important that the engine can be stopped immediately if an incident occurs and it is known in the art that particularly rapid intervention is obtained when a stop switch or button operating by pressing is available since an actuation known as a punch corresponds to an automatic reflex.

La présente invention résout le problème exposé dans ce qui précède en créant une nouvelle commande qui, en outre, empêche la remise en route du moteur même par une manoeuvre accidentelle. De plus, l'arrêt du moteur peut inter- . venir à tout moment pendant le fonctionnement de la minuterie. Par ailleurs, ces résultats sont obtenus en mettant en oeuvre des moyens extrêmement simples et robustes.The present invention solves the problem set out in the foregoing by creating a new control which, in addition, prevents the engine from being restarted even by accidental operation. In addition, stopping the engine can occur. come at any time during timer operation. Furthermore, these results are obtained by using extremely simple and robust means.

Conformément à l'invention, la commande mécanique à distance pour moteurs électriques antidéflagrants comportant une manivelle à rappel élastique est caractérisée en ce que ladite manivelle est reliée à un coulisseau présentant une rainure et une partie amincie qui sont disposées entre deux plaques pivotantes actionnées respectivement par une olive et une commande d'une minuterie, la position de l'olive par rapport aux plaques pivotantes permettant ou non l'actionnement du coulisseau par un bouton de manoeuvre.According to the invention, the mechanical control with dis tance for explosion-proof electric motors comprising an elastic return crank is characterized in that said crank is connected to a slide having a groove and a thinned part which are disposed between two pivoting plates actuated respectively by an olive and a timer control, the position of the olive relative to the pivoting plates allowing or not the actuation of the slider by an operating button.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

La commande illustrée au dessin est destinée à manoeuvrer une manivelle d'actionnement 1 d'un moteur électrique antidéflagrant 2. La manivelle 1 est normalement sollicitée par un ressort pour tourner dans le sens de la flèche f1, c'est-à-dire dans le sens interrompant automatiquement l'alimentation du moteur 2.The control illustrated in the drawing is intended to operate an actuating crank 1 of an explosion-proof electric motor 2. The crank 1 is normally biased by a spring to rotate in the direction of the arrow f 1 , that is to say in the direction automatically interrupting the supply of motor 2.

La durée de fonctionnement du moteur 2 doit être commandée par une minuterie 3 dont le fonctionnement ne doit être pris en considération qu'après que la manivelle 1 ait été amenée à pivoter dans le sens contraire à la flèche fi d'un angle suffisant. Par ailleurs, le moteur antidéflagrant 1 doit pouvoir être arrêté instantanément au moyen d'un bouton-poussoir 4 du type dit coup de poing.The operating time of the motor 2 must be controlled by a timer 3, the operation of which must only be taken into account after the crank 1 has been made to pivot in the opposite direction to the arrow f i of a sufficient angle. Furthermore, the explosion-proof motor 1 must be able to be stopped instantly by means of a push button 4 of the so-called punch type.

Comme l'illustre le dessin, la commande comporte avantageusement un boîtier 5 dans lequel est fixé un support 6 en tôle. Ce support forme un dos ou bord tombé 7 qui est parallèle à la face avant 5a du boîtier.As illustrated in the drawing, the control advantageously comprises a housing 5 in which a support 6 made of sheet metal is fixed. This support forms a back or dropped edge 7 which is parallel to the front face 5a of the housing.

Les fig. 1 et 2 montrent que le dos 7 présente des lumières 8 par lesquelles sont passées des pattes 9 à l'extrémité cambrée 9a qui sont formées par deux plaques 10 et 11. Les pattes 9 sont maintenues en arrière du dos 7 par deux ressorts 12, 13 constitués par des cordes à piano dont les extrémités sont engagées derrière les extrémités cambrées 9a desdites pattes, lesdits ressorts prenant par ailleurs appui à leur partie médiane contre des saillies 14, 15 formées à partir de crevés pratiqués dans le dos 7. Les ressorts 12, 13 sont précontraints de façon à exercer une poussée sur les pattes 9 et, par conséquent, de façon à faire pivoter les plaques 10, 11 dans le sens pour lequel ces plaques sont rapprochées l'une de l'autre.Figs. 1 and 2 show that the back 7 has openings 8 through which the legs 9 at the arched end 9a have passed which are formed by two plates 10 and 11. The legs 9 are held behind the back 7 by two springs 12, 13 formed by piano strings, the ends of which are engaged behind the arched ends 9a of the said legs, the said springs also bearing against their middle part against the projections 14, 15 formed from punctures in the back 7. The springs 12 , 13 are preloaded so as to exert a thrust on the legs 9 and, consequently, so as to rotate the plates 10, 11 in the direction for which these plates are brought closer to each other.

La plaque 10 présente un bord tombé 16 s'étendant sur une partie de sa longueur et qui est dirigé vers la plaque 11. De plus, la plaque 10 présente une portée d'appui 17 qui est destinée à coopérer avec une came 18 entraînée par la minuterie 3.The plate 10 has a dropped edge 16 extending over a part of its length and which is directed towards the plate 11. In addition, the plate 10 has a bearing surface 17 which is intended to cooperate with a cam 18 driven by the timer 3.

La plaque 11 présente de son côté deux bords tombés 19, respectivement 20, décalés l'un par rapport à l'autre. Le bord tombé 19 est destiné à coopérer avec un coulisseau 21 pouvant être manoeuvré par un bouton 22.The plate 11 has on its side two fallen edges 19, respectively 20, offset relative to each other. The dropped edge 19 is intended to cooperate with a slide 21 which can be operated by a button 22.

Le bord tombé 20 est destiné à coopérer avec une olive 23 présentant un méplat 24, ladite olive pouvant être commandée par le poussoir 4.The fallen edge 20 is intended to cooperate with an olive 23 having a flat 24, said olive being able to be controlled by the pusher 4.

Comme le montre la fig. 5, l'olive 23 est montée sur une tige 25 qui la relie au poussoir 4 et qui forme deux gorges 26, 26a pour des billes de verrouillage 27 maintenues par un jonc élastique 28. Ainsi, l'olive 23 peut être immobilisée dans deux positions, à savoir :

  • 1°) une position apparaissant aux fig. 5, 11 et 13 pour laquelle le bord tombé 20 de la plaque 11 prend appui directement sur la tige 25 de petit diamètre tandis que le bord tombé 16 de la plaque 10 prend appui sur le méplat 24 de l'olive 23. Dans cette position, le poussoir 4 est enfoncé et il n'est pas possible de mettre en route le moteur électrique 2. En effet, comme l'illustre le dessin, le coulisseau 21 qui peut être commandé par le bouton 22 présente une première partie 21a de petit diamètre qui est raccordée à la partie 21 proprement dite par un épaulement 29, ladite partie 21 présentant, par ailleurs, une rainure 30. L'épaulement 29 vient en butée contre le bord tombé 19 si l'on cherche à tirer le bouton 22, ce qui empêche que le coulisseau 21 déplace un câble 31 servant à l'actionnement de la manivelle 1. De même, le bord tombé 16 étant soulevé, il en est de même de la portée 17 et, par conséquent, celle-ci ne peut pas être actionnée par la came 18 de la minuterie 3;
  • 2°) une position apparaissant en particulier aux fig. 1, 4 et 9 pour laquelle le poussoir 4 est tiré et a entraîné la tige 25 qui est alors verrouillée par les billes 27 entrant dans les rainures 26a (fig. 5). Dans cette seconde position, le méplat 24 de l'olive 23 soulève le bord tombé 20 et il s'ensuit que le ressort 12 fait appliquer le bord tombé 16 de la plaque 10 sur le corps 21 du coulisseau. Dans cette position qui est la même que celle qu'occupait la plaque 10 dans le cas décrit sous 1°) ci-dessus, la portée 17 ne peut pas non plus être actionnée par la came 18 de la minuterie 3.
As shown in fig. 5, the olive 23 is mounted on a rod 25 which connects it to the pusher 4 and which forms two grooves 26, 26a for locking balls 27 held by an elastic ring 28. Thus, the olive 23 can be immobilized in two positions, namely:
  • 1) a position appearing in figs. 5, 11 and 13 for which the fallen edge 20 of the plate 11 is supported directly on the rod 25 of small diameter while the fallen edge 16 of the plate 10 is supported on the flat 24 of the olive 23. In this position , the pusher 4 is depressed and it is not possible to start the electric motor 2. In fact, as illustrated in the drawing, the slide 21 which can be controlled by the button 22 has a first part 21a of small diameter which is connected to the part 21 proper by a shoulder 29, said part 21 having, moreover, a groove 30. The shoulder 29 abuts against the fallen edge 19 if one seeks to pull the button 22, which prevents the slider 21 from moving a cable 31 used to actuate the crank 1. Similarly, the fallen edge 16 being raised, the same is true of the span 17 and, consequently, the latter cannot not be activated by cam 18 of timer 3;
  • 2) a position appearing in particular in FIGS. 1, 4 and 9 for which the pusher 4 is pulled and has driven the rod 25 which is then locked by the balls 27 entering the grooves 26a (fig. 5). In this second position, the flat 24 of the olive 23 raises the fallen edge 20 and it follows that the spring 12 causes the fallen edge 16 of the plate 10 to be applied to the body 21 of the slide. In this position which is the same as that occupied by the plate 10 in the case described under 1 °) above, the por tee 17 cannot be actuated by cam 18 of timer 3 either.

Lorsqu'on désire faire fonctionner le moteur 2, il est nécessaire d'amener le poussoir 4 dans la seconde position décrite ci-dessus, de tirer sur le bouton 22 pour l'amener dans la position représentée aux fig. 7 et 10, ce qui fait que le ressort 12 fait pivoter la plaque 10, de façon que le bord tombé 16 entre dans la rainure 30 du coulisseau 21 qui est ainsi verrouillé. La traction exercée sur le bouton 22 a amené la manivelle 1 en position de travail.When it is desired to operate the motor 2, it is necessary to bring the pusher 4 to the second position described above, to pull the button 22 to bring it to the position shown in FIGS. 7 and 10, which causes the spring 12 to pivot the plate 10, so that the dropped edge 16 enters the groove 30 of the slide 21 which is thus locked. The traction exerted on the button 22 brought the crank 1 into the working position.

Lorsque le temps compté par la minuterie 3 est écoulé, la partie haute de la came 18 soulève la portée 17, ce qui est représenté à la fig. 3, de sorte que la plaque 10 est elle-même soulevée pour que le bord tombé 16 échappe à la rainure 30 en libérant le coulisseau 21 qui est ramené à la position illustrée à la fig. 1 par la force élastique exercée sur la manivelle 1 dans le sens de la flèche fi. En conséquence, le moteur s'arrête.When the time counted by the timer 3 has elapsed, the upper part of the cam 18 raises the span 17, which is shown in FIG. 3, so that the plate 10 is itself raised so that the dropped edge 16 escapes from the groove 30 by releasing the slide 21 which is brought back to the position illustrated in FIG. 1 by the elastic force exerted on the crank 1 in the direction of the arrow f i . As a result, the engine stops.

Le moteur peut être remis en fonctionnement en exerçant une nouvelle traction sur le bouton 22 et en réglant à nouveau la minuterie.The motor can be put back into operation by exerting a new pull on button 22 and by resetting the timer.

En supposant maintenant que le moteur 2 est en cours de fonctionnement, c'est-à-dire que la plaque 10 maintient, par son bord tombé 16, le coulisseau 21 dans la position illustrée à la fig. 10 et qu'il survient un incident obligeant à arrêter immédiatement le moteur, il suffit de pousser brusquement le poussoir 4 pour l'amener dans la position illustrée aux fig. 11 et 13, c'est-à-dire que le bord tombé 16 de la plaque 10 est soulevé et prend appui sur le méplat 24 de l'olive 23 tandis que le bord tombé 20 de la plaque 11 vient en appui sur la tige 25. Dans ce cas, le bord tombé 16 libère la rainure 30 du coulisseau 21 pour permettre à la manivelle 1 de revenir à la position de non-fonctionnement du moteur et le coulisseau 21 ne peut plus être actionné à partir du bouton 22 puisque le bord tombé 19 de la plaque 11 se trouve alors devant l'épaulement 29. Une remise en fonctionnement n'est possible qu'après un nouvel armement du poussoir 4.Assuming now that the motor 2 is in operation, that is to say that the plate 10 maintains, by its fallen edge 16, the slide 21 in the position illustrated in FIG. 10 and that an incident occurs which requires the engine to be stopped immediately, it suffices to suddenly push the pusher 4 to bring it into the position illustrated in FIGS. 11 and 13, that is to say that the fallen edge 16 of the plate 10 is raised and bears on the flat 24 of the olive 23 while the fallen edge 20 of the plate 11 comes to bear on the stem 25. In this case, the fallen edge 16 releases the groove 30 of the slide 21 to allow the crank 1 to return to the non-operating position of the motor and the slide 21 can no longer be actuated from the button 22 since the fallen edge 19 of the plate 11 is then in front of the shoulder 29. A restart is only possible after a new arming of the pusher 4.

L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, le câble 31 pourrait être remplacé par une commande hydraulique.The invention is not limited to the embodiment shown and described in detail, since various modifications can be made without departing from its scope. In particular, the cable 31 could be replaced by a hydraulic control.
