Description

La présente invention concerne un dispositif de commutation disposé dans un programmateur de machine électrodomestique, programmateur comprenant un bloc de cames-programmes actionnant des lames porte-contacts, une première chaine cinématique pour entrainer le bloc de cames en rotation pas à pas, une deuxième chaine cinématique pour entraîner le bloc de cames en rotation rapide, le dispositif de commutation comprenant un interrupteur mécanique, monté en série avec les lames porte-contacts, et des moyens de commande dudit interrupteur, pour alimenter en énergie des organes électriques de la machine.
Comme machines électrodomestiques auxquelles peut s'appliquer l'invention, on peut citer les machines à laver le linge ou la vaisselle.The present invention relates to a switching device arranged in a household electrical machine programmer, programmer comprising a block of program cams actuating contact carrier blades, a first kinematic chain for driving the block of cams in stepwise rotation, a second chain kinematic for driving the block of cams in rapid rotation, the switching device comprising a mechanical switch, mounted in series with the contact carrier blades, and control means of said switch, for supplying energy to the electrical components of the machine.
As household electrical appliances to which the invention may apply, mention may be made of washing machines for washing clothes or dishes.

Un dispositif du type défini ci-dessus permet de couper l'alimentation en énergie électrique d'une pluralité d'organes de l'appareil, pendant certains déplacements d'un bloc de cames de programmation desdits organes.A device of the type defined above makes it possible to cut off the supply of electrical energy to a plurality of organs of the apparatus, during certain movements of a block of cams for programming said organs.

Dans un programmateur, un ensemble, ou bloc, de cames-programmes, destinées à actionner des lames porte contact reliant des organes électriques à une source de tension, peut être entrainé en rotation pas à pas par l'intermédiaire d'une cinématique particulière, dite d'entrainement pas à pas, ou en rotation rapide par l'intermédiaire d'une autre cinématique particulière, dite d'entrainement rapide.In a programmer, a set, or block, of program cams, intended to actuate contact-carrying blades connecting electrical members to a voltage source, can be rotated step by step by means of a specific kinematics, so-called step-by-step training, or in rapid rotation by means of another particular kinematics, called rapid training.

Les programmes de lavage sont déterminés par les profils des cames-programmes, leur rotation et leur arrêt temporisé.
Plus précisemment, une position angulaire du bloc de cames-programmes correspond à une combinaison particulière des profils des différentes cames qui le constituent, de leur action sur les lames porte- contacts, et entraîne donc la mise sous tension de certains organes et la mise hors tension d'autres organes.
On comprend ainsi que chaque position angulaire du bloc cames représente une étape particulière d'un programme de lavage.The washing programs are determined by the profiles of the program cams, their rotation and their timed stop.
More precisely, an angular position of the block of program cams corresponds to a particular combination of the profiles of the various cams which constitute it, of their action on the contact-carrying blades, and therefore causes the tensioning of certain members and the deactivation tension of other organs.
It is thus understood that each angular position of the cam block represents a particular step in a washing program.

Pendant le déroulement normal d'un programme, le bloc-cames est généralement entraîné en rotation pas à pas, et les étapes de lavage réalisées correspondent, sur le bloc-cames, à des secteurs angulaires adjacents et successifs.During the normal course of a program, the cam block is generally driven in step-by-step rotation, and the washing steps carried out correspond, on the cam block, to adjacent and successive angular sectors.

Cependant, l'existence d'une cinématique d'entraînement rapide du bloc-cames permet d'enrichir les possibilités du programmateur en autorisant, au cours d'un programme, la combinaison d'étapes éloignées entre elles.However, the existence of a fast drive kinematics of the cam block makes it possible to enrich the possibilities of the programmer by authorizing, during a program, the combination of distant steps between them.

Le bloc-cames est alors entraîné rapidement d'une position angulaire donnée vers une position angulaire éloignée, non adjacente à la précédente.The cam block is then quickly driven from a given angular position to a distant angular position, not adjacent to the previous one.

Ceci peut aussi se produire à la fin d'un programme, lorsque le bloc-cames doit être ramené en position de repos.This can also happen at the end of a program, when the cam block has to be returned to the rest position.

Pendant la rotation rapide du bloc-cames, les positions angulaires à éviter sont néanmoins balayées, les lames porte-contacts actionnées, et une série de commutations rapides se produit, entre la source de tension et les organes électriques de l'appareil.
Ces mises sous tension brèves et intempestives sont à l'origine de bruits désagréables, de parasites électriques et radioélectriques.
On sait qu'il est préférable de couper l'alimentation en énergie des organes de l'appareil pendant la rotation rapide du bloc-cames, au lieu de lutter, par des blindages et protections diverses, contre les effets nocifs de ces parasites.
Pour ce faire, on utilise des dispositifs de commutation comprenant des moyens interrupteurs, en série entre la source de tension et les lames porte-contacts, et des moyens de commande de ces moyens interrupteurs, sensibles au type d'entrainement, pas à pas ou rapide, que subit le bloc-cames.During the rapid rotation of the cam block, the angular positions to be avoided are nevertheless scanned, the contact carrier blades actuated, and a series of rapid switches occurs, between the voltage source and the electrical components of the device.
These brief and untimely power-ups are the source of unpleasant noise, electrical and radio interference.
It is known that it is preferable to cut off the energy supply to the organs of the apparatus during the rapid rotation of the cam block, instead of fighting, by various shields and protections, against the harmful effects of these parasites.
To do this, use is made of switching devices comprising switch means, in series between the voltage source and the contact carrier blades, and means for controlling these switch means, sensitive to the type of drive, step by step or fast, which the cam block undergoes.

Il existe plusieurs filières technologiques qui permettent de réaliser de tels dispositifs de commutation.There are several technological sectors which make it possible to produce such switching devices.

On peut, par exemple, utiliser des relais électromécaniques qui nécessitent un dispositif de commande électrique.One can, for example, use electromechanical relays which require an electrical control device.

On peut aussi utiliser des interrupteurs mécaniques, du type interrupteur à lame souple par exemple, qui nécessitent un dispositif de commande mécanique.
La fiabilité et la simplicité des interrupteurs mécaniques, ainsi que leur faible coût, justifie la préférence qui leur est généralement accordée.
Il n'est cependant pas aisé d'obtenir des moyens de commande qui agissent mécaniquement sur ces interrupteurs.Mechanical switches can also be used, of the flexible blade switch type for example, which require a mechanical control device.
The reliability and simplicity of mechanical switches, as well as their low cost, justifies the preference which is generally granted to them.
However, it is not easy to obtain control means which act mechanically on these switches.

On connait déjà un certain nombre de dispositifs de commande, plus ou moins complexes, dont le principal inconvénient est d'entraîner une profonde modification des éléments constitutifs d'un programmateur auquel on veut les adapter.We already know a number of control devices, more or less complex, the main drawback of which is to cause a profound modification of the components of a programmer to which we want to adapt them.

La présente invention vise à pallier cet inconvénient.The present invention aims to overcome this drawback.

A cet effet, la présente invention concerne un dispositif de commutation du type défini ci-dessus, caractérisé par le fait que lesdits moyens de commande comprennent une bascule pivotant sur un axe fixe, des moyens pour transformer les rotations de ladite bascule en mouvements de commande et les appliquer audit interrupteur, des moyens permettant à ladite bascule de coopérer simultanément avec une première roue dentée associée à ladite première chaine cinématique et une deuxième roue dentée associée à ladite deuxième chaine cinématique, lesdits moyens de coopération étant agencés de façon à faire pivoter ladite bascule dans une première position angulaire de commande dudit interrupteur lorsque le bloc de came est entrainé par ladite première chaine cinématique, et à faire pivoter ladite bascule dans une deuxième position angulaire de commande lorsque le bloc de came est entrainé par ladite deuxième chaine cinématique.To this end, the present invention relates to a switching device of the type defined above, characterized in that said control means comprise a rocker pivoting on a fixed axis, means for transforming the rotations of said rocker into control movements and applying them to said switch, means allowing said rocker to cooperate simultaneously with a first toothed wheel associated with said first kinematic chain and a second toothed wheel associated with said second kinematic chain, said cooperation means being arranged so as to pivot said rocker in a first angular position of control of said switch when the cam block is driven by said first kinematic chain, and to pivot said rocker in a second angular position of control when the cam block is driven by said second kinematic chain.

Avantageusement l'axe de la bascule est confondu avec l'axe de rotation de ladite deuxième roue dentée, lesdits moyens de coopération de la bascule avec lesdites première et deuxième roues dentées comprennent un pignon rotatif, monté excentré sur la bascule et agencé pour coopérer avec ladite deuxième roue dentée, ladite première roue dentée étant agencée pour coopérer avec ledit pignon, lorsque celui-ci parcourt un arc de trajectoire AB centré sur l'axe de la bascule, et un moyen de rappel élastique dudit pignon vers ladite première roue dentée pour rappeler ledit pignon à coopérer avec ladite première roue.Advantageously, the axis of the rocker is coincident with the axis of rotation of said second toothed wheel, said means of cooperation of the rocker with said first and second toothed wheels comprise a rotary pinion, mounted eccentrically on the rocker and arranged to cooperate with said second gear, said first gear being arranged to cooperate with said pinion, when the latter traverses an arc of trajectory AB centered on the axis of the rocker, and an elastic return means of said pinion towards said first toothed wheel to remind said pinion to cooperate with said first wheel.

Une came 700, dite came d'inversion, entraînée à vitesse constante et permanente par le groupe 100 d'engrenages réducteurs, coopère avec un cliquet 800 pour entraîner le bloc-cames 600 en rotation pas à pas.The rear module supports a first motor 400 associated with a group 100 of reduction gears, for the stepping drive of the cam block 600, and a second motor 500, associated with another group 200 of reduction gears, for the quick drive of the cam block 600.
The cam block 600, attached to the rear module, comprises a number of cams attached to one another and integral in rotation with one another.
A cam 700, called the reversing cam, driven at constant and permanent speed by the group 100 of reduction gears, cooperates with a pawl 800 to drive the cam block 600 in step-by-step rotation.

Le premier groupe d'engrenage réducteurs 100 comprend ici un pignon 1, solidaire de l'arbre du premier moteur, coopérant avec la denture extérieure d'une roue 2, solidaire d'un pignon 3 coopérant avec une roue dentée 4, elle-même solidaire d'un pignon 5 coopérant avec une roue dentée 6, superposée à la roue 2, comportant un axe commun avec la roue 2, et solidaire d'un pignon 7 coopérant avec une roue dentée 8, elle-même solidaire d'un pignon 9 coopérant avec une roue dentée 10, elle-même solidaire d'un pignon 11, dernier élément du groupe réducteur 100.The first group of reduction gears 100 here comprises a pinion 1, integral with the shaft of the first motor, cooperating with the external toothing of a wheel 2, integral with a pinion 3 cooperating with a toothed wheel 4, itself secured to a pinion 5 cooperating with a toothed wheel 6, superimposed on the wheel 2, having a common axis with the wheel 2, and secured to a pinion 7 cooperating with a toothed wheel 8, itself secured to a pinion 9 cooperating with a toothed wheel 10, itself secured to a pinion 11, the last element of the reduction unit 100.

Le pignon 11 entraîne en rotation continue la came d'inversion 700 et supporte le cliquet 800 d'entraînement pas à pas du bloc-cames 600.The pinion 11 drives the reversing cam 700 in continuous rotation and supports the pawl 800 for step-by-step drive of the cam block 600.

Le deuxième groupe d'engrenages réducteurs 200 comprend un pignon 20, solidaire de l'arbre du deuxième moteur, qui coopère avec la denture extérieure d'une roue 21, solidaire d'un pignon 22 coopérant avec une roue dentée 23, elle-même solidaire d'un pignon 24 coopérant avec une roue dentée 25, associée à un pignon 26, coopérant directement avec une denture du bloc-cames 600, et permettant ainsi l'entraînement rapide et continu du bloc-cames 600.The second group of reduction gears 200 comprises a pinion 20, integral with the shaft of the second motor, which cooperates with the external toothing of a wheel 21, integral with a pinion 22 cooperating with a toothed wheel 23, itself integral with a pinion 24 cooperating with a toothed wheel 25, associated with a pinion 26, cooperating directly with a toothing of the cam block 600, and thus allowing the rapid and continuous drive of the cam block 600.

La découpe particulière des cames-programmes, appelée aussi profils de cames, permet d'actionner des lames 900 porte-contacts reliant des organes électriques 950 à une source de tension d'alimentation 960 desdits organes 950.
Lorsque le bloc-came 600 est entraîné en rotation rapide par le deuxième moteur 500 et le groupe réducteur 200, les lames 900 porte-contacts sont actionnées au gré du défilement des profils de cames et le dispositif de l'invention intervient pendant ces instants pour isoler les lames 900 porte-contacts de la source de tension d'alimentation 960.The particular cutting of the program cams, also called cam profiles, makes it possible to actuate contact-holder blades 900 connecting electrical members 950 to a supply voltage source 960 of said members 950.
When the cam block 600 is driven in rapid rotation by the second motor 500 and the reduction unit 200, the contact carrier blades 900 are actuated as the cam profiles run and the device of the invention operates during these moments to isolate the contact carrier blades 900 from the supply voltage source 960.

Le dispositif de l'invention comprend un interrupteur 70 à lames souples, comprenant quatre plots fixes de contact 76, 77, 78, 79, disposés dans un même plan, et deux lames contacts 75, 80, flexibles et élastiques. La lame contact 75 comporte une extrêmité fixée, par exemple par soudage, au plot 76.
La lame contact 75 est repliée sensiblement à mi-distance de ses deux extrémités et sa deuxième extrêmité 751 vient naturellement au contact du plot 78, du fait de l'élasticité de la lame 75, lorsqu'aucune action n'est exercée sur elle.
De la même façon, la lame contact 80, repliée à mi-distance de ses extrêmités, est fixée par une extrêmité au plot 79, et sa deuxième extrêmité 81 vient naturellement au contact du plot 77, lorsqu'aucune action n'est exercée sur elle.The device of the invention comprises a switch 70 with flexible blades, comprising four fixed contact pads 76, 77, 78, 79, arranged in the same plane, and two contact blades 75, 80, flexible and elastic. The contact blade 75 has one end fixed, for example by welding, to the stud 76.
The contact blade 75 is folded substantially halfway between its two ends and its second end 751 comes naturally into contact with the pad 78, due to the elasticity of the blade 75, when no action is exerted on it.
Likewise, the contact blade 80, folded halfway between its ends, is fixed by one end to the pad 79, and its second end 81 comes naturally into contact with the pad 77, when no action is exerted on she.

L'interrupteur 70 comprend aussi un levier 71 comportant un corps 79, sensiblement longitudinal, avec deux excroissances 73 et 74 disposées face à face sur une extrêmité du corps 79, un axe de rotation 72 étant disposé à une autre extrêmité du corps 79.The switch 70 also includes a lever 71 comprising a body 79, which is substantially longitudinal, with two protuberances 73 and 74 arranged face to face on one end of the body 79, an axis of rotation 72 being disposed at another end of the body 79.

L'excroissance 74 comporte deux becs 740 et 741. Le levier 71 est disposé de façon à ce que le bec 740 soit en regard de l'extrêmité 751 de la lame 75, le bec 741 étant alors en regard de l'extrêmité de la lame 80, fixée sur le plot 79, et l'excroissance 73, en regard de moyens de commande de l'interrupteur 70, décrits ci-après.The protuberance 74 has two spouts 740 and 741. The lever 71 is arranged so that the spout 740 faces the end 751 of the blade 75, the spout 741 then being opposite the end of the blade 80, fixed on the pad 79, and the protrusion 73, opposite the control means of the switch 70, described below.

Le dispositif de l'invention peut occuper une position de repos (fig.1) et une position active (fig.2). La position de repos est occupée lorsque le bloc-cames 600 est en rotation pas à pas.The device of the invention can occupy a rest position (fig. 1) and an active position (fig. 2). The rest position is occupied when the cam block 600 is rotating step by step.

En position de repos, l'excroissance 73 du levier 71 ne subit pas l'action des moyens de commande, le bec 740 de l'excroissance 74 n'appuie pas sur la lame souple 75, et le bec 741 n'appuie pas sur la lame souple 80.In the rest position, the protrusion 73 of the lever 71 does not undergo the action of the control means, the spout 740 of the protrusion 74 does not press on the flexible blade 75, and the spout 741 does not press on the flexible blade 80.

En position de repos toujours, la lame souple 75 assure donc la continuité électrique entre les plots 76 et 78, et la lame souple 80 assure la continuité électrique entre les plots 79 et 77.Still in the rest position, the flexible blade 75 therefore provides electrical continuity between the pads 76 and 78, and the flexible blade 80 provides electrical continuity between the pads 79 and 77.

Une butée 752 est disposée près du point de pliage de la lame 75, du côté fixé au plot 76, de façon à maintenir la partie de la lame 75 qui est située entre le plot 76 et le point de pliage, lorsqu'une action est exercée par le bec 740 sur l'extrêmité 751 de la lame 75. De ce fait, une action du bec 740 sur l'extrêmité 751 de la lame 75, a pour effet de plier davantage la lame 75, d'éloigner l'extrêmité 751 du plot 78, et rompt ainsi le contact électrique entre la lame 75 et le plot 78.A stop 752 is arranged near the folding point of the blade 75, on the side fixed to the pad 76, so as to maintain the part of the blade 75 which is located between the pad 76 and the folding point, when an action is exerted by the spout 740 on the end 751 of the blade 75. As a result, an action of the spout 740 on the end 751 of the blade 75, has the effect of bending the blade 75 further, of moving the end away 751 of the pad 78, and thus breaks the electrical contact between the blade 75 and the pad 78.

Une autre autre butée 82 est disposée près de la lame 80, plus précisément près de l'extrêmité 81 en contact avec le plot 77, de façon à ce qu'une action exercée par le bec 741, sur l'extrêmité de la lame 80 soudée au plot 79, aie pour effet d'ouvrir la lame 80, tout en éloignant l'extrêmité 81 du plot 77, le contact électrique entre la lame 80 et le plot 77 étant ainsi rompu.Another other stop 82 is disposed near the blade 80, more precisely near the end 81 in contact with the stud 77, so that an action exerted by the spout 741, on the end of the blade 80 welded to the pad 79, has the effect of opening the blade 80, while moving the end 81 away from the pad 77, the electrical contact between the blade 80 and the pad 77 being thus broken.

Les deux plots 77 et 78 étant juxtaposés, et les extrêmités 81 et 751 des deux lames 80 et 75 étant en regard, on comprendra alors, que lorsqu'une action est exercée par le levier 71 sur les lames 75 et 80, par l'intermédiaire des becs 740 et 741 de l'excroissance 74, les deux lames se rejoignent à mi-distance des plots 77 et 78, et créent ainsi un nouveau contact électrique, entre les plots 76 et 79, sur lesquels elles sont respectivement soudées.les deux autres plots 77 et 78 étant alors isolés électriquement.The two pads 77 and 78 being juxtaposed, and the ends 81 and 751 of the two blades 80 and 75 being opposite, it will then be understood that when an action is exerted by the lever 71 on the blades 75 and 80, by the intermediate the nozzles 740 and 741 of the protrusion 74, the two blades meet halfway between the pads 77 and 78, and thus create a new electrical contact, between the pads 76 and 79, on which they are respectively welded. two other pads 77 and 78 then being electrically isolated.

Le plot 76 étant relié à la source de tension d'alimentation 960 et le plot 78 aux différentes lames 900 porte-contacts du programmateur 300, on comprend donc que l'alimentation en énergie des organes électriques 950 est possible lorsque le bloc-cames 600 est en rotation pas à pas, c'est à dire lorsque le dispositif de l'invention est au repos.The pad 76 being connected to the supply voltage source 960 and the pad 78 to the various blades 900 contact carrier of the programmer 300, it is therefore understood that the power supply to the electrical components 950 is possible when the cam block 600 is rotating step by step, that is to say when the device of the invention is at rest.

Tous les éléments décrits jusqu'ici sont connus et les éléments permettant le fonctionnement du dispositif de l'invention, c'est à dire lesdits moyens de commande de l'interrupteur 70, sont maintenant décrits.All the elements described so far are known and the elements allowing the device of the invention to operate, ie said means for controlling the switch 70, are now described.

Le dispositif de l'invention comprend en outre une bascule 30, un pignon 40, un ressort 50, une came 60 et une roue dentée 12.
La bascule 30 est une pièce sensiblement plate, de forme triangulaire, proche d'un triangle équilatéral, et offre donc trois extrêmités aux trois angles du triangle.
Un axe de rotation 32, disposé près d'une première extrêmité, permet à la bascule 30 de pivoter librement. L'axe 32 est confondu avec l'axe de la roue 23 et du pignon 24 déjà décrits.The device of the invention further comprises a rocker 30, a pinion 40, a spring 50, a cam 60 and a toothed wheel 12.
The lever 30 is a substantially flat piece, of triangular shape, close to an equilateral triangle, and therefore offers three ends at the three angles of the triangle.
A rotation axis 32, disposed near a first end, allows the rocker 30 to pivot freely. The axis 32 coincides with the axis of the wheel 23 and the pinion 24 already described.

Un pignon 40, rotatif autour d'un axe logé dans la bascule, est disposé près d'une deuxième extrêmité de la bascule 30.A pinion 40, rotatable around an axis housed in the rocker, is arranged near a second end of the rocker 30.

Le pignon 40 est agencé de façon à coopérer avec la denture, de la roue 23, la distance entre l'axe du pignon 40 et l'axe 32 de la bascule 30 étant sensiblement égale à la somme des rayons du pignon 40 et de la roue 23.The pinion 40 is arranged so as to cooperate with the toothing of the wheel 23, the distance between the axis of the pinion 40 and the axis 32 of the lever 30 being substantially equal to the sum of the radii of the pinion 40 and the wheel 23.

Un ergot 31, de forme cylindrique, solidaire de la bascule 30 et perpendiculaire au plan formé par celle-ci, est disposé près d'une troisième extrêmité.
En considérant cette partie du dispositif, on peut remarquer qu'une rotation d'un tour de la bascule 30 entraînerait le pignon 40 à effectuer un tour complet autour de la roue 23, en roulant sur la denture périphérique de cette même roue 23.
Cependant, dans le dispositif, une telle rotation d'un tour n'est pas possible, car le pignon 40 est rappelé en direction de l'axe de la roue 12, par un ressort relié par une extrêmité à l'axe du pignon 40 et, par une autre extrêmité, à l'axe de la roue 12.A lug 31, of cylindrical shape, integral with the lever 30 and perpendicular to the plane formed by the latter, is disposed near a third end.
Considering this part of the device, it can be noted that a rotation of one revolution of the lever 30 would cause the pinion 40 to make a complete revolution around the wheel 23, by rolling on the peripheral toothing of this same wheel 23.
However, in the device, such a rotation of a revolution is not possible, since the pinion 40 is biased towards the axis of the wheel 12, by a spring connected by one end to the axis of the pinion 40 and, at another end, to the axis of the wheel 12.

La roue 12 est disposée face à la roue 23, sensiblement dans le même plan, et de façon à ce que l'écartement entre leurs dentures respectives permette le passage du pignon 40 tout en le faisant coopérer avec la denture de la roue 12.
Grâce à la profondeur des dentures du pignon 40 et de la roue 12, on constate qu'il existe un arc AB de trajectoire du pignon 40 correspondant à un angle de rotation α de la bascule 30, sur lequel le pignon 40 coopère avec la roue 12.The wheel 12 is disposed facing the wheel 23, substantially in the same plane, and so that the spacing between their respective teeth allows the passage of the pinion 40 while making it cooperate with the teeth of the wheel 12.
Thanks to the depth of the teeth of the pinion 40 and of the wheel 12, it can be seen that there is an arc AB of trajectory of the pinion 40 corresponding to an angle of rotation α of the rocker 30, on which the pinion 40 cooperates with the wheel. 12.

Par ailleurs, la denture de la roue 12 coopère aussi de façon permanente avec le pignon 9, du groupe d'engrenages réducteurs 100, dédié à l'entraînement pas à pas du bloc-cames 600.
La roue 12 est donc solidaire en rotation du groupe réducteur 100. Elle lui est associée.Furthermore, the toothing of the wheel 12 also cooperates permanently with the pinion 9, of the group of reducing gears 100, dedicated to the step-by-step drive of the cam block 600.
The wheel 12 is therefore integral in rotation with the reduction unit 100. It is associated with it.

La came 60 est une pièce sensiblement plate, pivotant autour d'un axe fixe 65 et disposée dans un plan sensiblement parallèle au plan forme par la bascule 30.
La came 60 comporte deux saillies 61 et 63. Dans la première saillie 61 est pratiquée une encoche 62, qui reçoit l'ergot 31 de la bascule 30.The cam 60 is a substantially flat part, pivoting about a fixed axis 65 and disposed in a plane substantially parallel to the plane formed by the rocker 30.
The cam 60 has two projections 61 and 63. In the first projection 61, a notch 62 is formed, which receives the lug 31 of the rocker 30.

Cette encoche 62 est ici pratiquée dans toute l'épaisseur de la came 60, car le corps de l'ergot 31 se termine au delà du plan formé par la came 60.This notch 62 is here practiced throughout the entire thickness of the cam 60, since the body of the lug 31 ends beyond the plane formed by the cam 60.

Dans le plan formé par la came 60, l'encoche 62 est suffisamment profonde, de façon à toujours contenir l'ergot 31 lorsque la bascule 30 effectue une rotation correspondant à l'angle α mentionné ci-dessus.In the plane formed by the cam 60, the notch 62 is sufficiently deep, so as to always contain the lug 31 when the rocker 30 rotates corresponding to the angle α mentioned above.

Toujours dans le même plan, la longueur de l'encoche 62 est ici plusieurs fois supérieure au diamètre de l'ergot 31, de façon à laisser possible un débattement angulaire, ou jeu, entre la came 60 et la bascule 30.Still in the same plane, the length of the notch 62 is here several times greater than the diameter of the lug 31, so as to allow an angular clearance, or clearance, between the cam 60 and the rocker 30.

La deuxième saillie 63 comporte une rampe 64 formant un plan passant près de l'axe 65 de la came 60 et se terminant par un arrondi joignant un plateau 165 sensiblement perpendiculaire à la rampe 64.The second projection 63 includes a ramp 64 forming a plane passing near the axis 65 of the cam 60 and ending in a rounded joining a plate 165 substantially perpendicular to the ramp 64.

Ayant décrit la structure du dispositif de l'invention, son fonctionnement peut maintenant être abordé.Having described the structure of the device of the invention, its operation can now be discussed.

La figure 1 représente l'ensemble du dispositif de l'invention, au repos, lorsque le bloc-cames 600 est en rotation pas à pas.Figure 1 shows the entire device of the invention, at rest, when the cam block 600 is rotating step by step.

Dans cette situation, la roue 23 est arrêtée, ainsi que le groupe réducteur 200 et le moteur 500 d'entraînement rapide du bloc-cames. La roue 12 est entraînée en rotation par le groupe réducteur 100 et le moteur 400 d'entraînement pas à pas du bloc-cames, selon un sens de rotation inverse de celui des aiguilles d'une montre, indiqué sur la figure 1 par une flèche.In this situation, the wheel 23 is stopped, as well as the reduction unit 200 and the motor 500 for fast driving of the cam block. The wheel 12 is rotated by the reduction unit 100 and the motor 400 for stepping the cam block, in a direction of rotation opposite to that of the needles of a watch, indicated in FIG. 1 by an arrow .

L'effet conjugué de la rotation de la roue 12 et de la force exercée par le ressort de rappel 50 maintient le pignon 40 dans une position stable A, à la limite de coopération avec la roue 12.The combined effect of the rotation of the wheel 12 and the force exerted by the return spring 50 keeps the pinion 40 in a stable position A, at the limit of cooperation with the wheel 12.

On notera que le pignon 40 ne tourne pas, puisqu'il est solidaire en rotation de la roue 23, qui est immobile.
La denture de la roue 12 exerce donc un frottement permanent sur les dents du pignon 40 qui lui sont en regard.Note that the pinion 40 does not rotate, since it is integral in rotation with the wheel 23, which is stationary.
The teeth of the wheel 12 therefore exerts a permanent friction on the teeth of the pinion 40 which are opposite it.

Tous les autres éléments du dispositif sont au repos, l'ergot 31, logé dans l'encoche 62 de la came 60 n'exerce pas de pression sur les parois de l'encoche, ni donc sur la came 60.All the other elements of the device are at rest, the lug 31, housed in the notch 62 of the cam 60 does not exert pressure on the walls of the notch, nor therefore on the cam 60.

La came 60 n'exerce pas non plus de pression sur le levier 71, la lame 75 est en butée sur le plot 78 de l'interrupteur 70 et la lame 80 en butée sur le plot 77.The cam 60 also exerts no pressure on the lever 71, the blade 75 is in abutment on the pad 78 of the switch 70 and the blade 80 in abutment on the pad 77.

Dès lors que le moteur 500 d'avance rapide est mis en route, la disposition des éléments se modifie :
   La roue 23 se met tout d'abord en rotation, selon un sens identique à celui de la roue 12, mais avec une vitesse de rotation supérieure.As soon as the fast-forward motor 500 is started, the arrangement of the elements changes:
The wheel 23 starts to rotate first, in a direction identical to that of the wheel 12, but with a higher speed of rotation.

Selon un premier mode de mise en oeuvre de l'invention, on n'utilise pas les plots 77 et 79 de l'interrupteur 70, ainsi que la lame 80 qui les relie électriquement.According to a first embodiment of the invention, the pads 77 and 79 of the switch 70 are not used, as is the blade 80 which connects them electrically.

Le moteur 400 pour l'entraînement pas à pas du bloc-cames 600 est alimenté en permanence, la roue 12 reste donc entraînée en rotation par le groupe 100 lorsque le moteur 500 d'entraînement rapide fonctionne.
La vitesse différentielle des deux roues 23 et 12 est telle que le pignon 40 est alors entraîné vers une autre position B, en parcourant un arc AB.The motor 400 for the stepping drive of the cam block 600 is continuously supplied, the wheel 12 therefore remains driven in rotation by the group 100 when the motor 500 rapid drive operates.
The differential speed of the two wheels 23 and 12 is such that the pinion 40 is then driven to another position B, traversing an arc AB.

En B, la denture du pignon 40 ne coopère presque plus avec la roue 12, et le ressort 50 empêche le pignon 40 d'être entraîné au delà de ce point B. La figure 2 illustre cette situation.At B, the toothing of the pinion 40 almost no longer cooperates with the wheel 12, and the spring 50 prevents the pinion 40 from being driven beyond this point B. FIG. 2 illustrates this situation.

Pendant la translation du pignon 40 le long de l'arc AB, et la rotation de la bascule 30 correspondant à l'angle déjà mentionné, l'ergot 31, après avoir franchi la longueur, ou jeu, de l'encoche 62 de la came 60, transmet l'effort du pignon à la came 60 qui se déplace angulairement et fait pivoter le levier 71 sur son axe 72, grâce à la coopération de la rampe 64 avec l'excroissance 73 du levier 71.
On notera que le dispositif est calibré de façon à ce qu'en fin de course du pignon 40, c'est à dire au point B, l'excroissance 73 soit en contact avec le plateau 65, le dispositif étant alors dans un état stable (fig.2).During the translation of the pinion 40 along the arc AB, and the rotation of the rocker 30 corresponding to the angle already mentioned, the lug 31, after having crossed the length, or clearance, of the notch 62 of the cam 60, transmits the force of the pinion to cam 60 which moves angularly and makes the lever 71 pivot on its axis 72, thanks to the cooperation of the ramp 64 with the projection 73 of the lever 71.
It will be noted that the device is calibrated so that at the end of the pinion 40 stroke, that is to say at point B, the protrusion 73 is in contact with the plate 65, the device then being in a stable state (fig. 2).

Lorsque l'excroissance 73 est en contact avec le plateau 65, de la came 60, le bec 740 de l'excroissance 74 est en appui sur la lame 75 de l'interrupteur et l'extrêmité de la lame 75 est maintenue éloignée du plot 78.When the protuberance 73 is in contact with the plate 65 of the cam 60, the spout 740 of the protrusion 74 is in contact with the blade 75 of the switch and the end of the blade 75 is kept away from the pad 78.

Le plot 78 n'est alors plus en contact avec la lame 75 et la tension de source 960 n'est plus délivrée aux lames 900 porte-contacts et aux organes électriques 950 qui pourraient être alimentés au gré des fluctuations des profils de cames. On évite ainsi, pendant la rotation rapide du bloc-cames 600, la création de parasites électriques sur les lignes d'alimentation.The stud 78 is then no longer in contact with the blade 75 and the source voltage 960 is no longer delivered to the contact-carrying blades 900 and to the electrical members 950 which could be supplied according to the fluctuations of the cam profiles. This avoids, during the rapid rotation of the cam block 600, the creation of electrical interference on the supply lines.

Lorsque, ensuite, le moteur 500 d'avance rapide du bloc-came 600 est arrêté, la roue 23 redevient immobile et la roue 12 entraîne le pignon 40 vers la position initiale A.When, then, the rapid advance motor 500 of the cam block 600 is stopped, the wheel 23 becomes immobile again and the wheel 12 drives the pinion 40 to the initial position A.

Le processus effectué par le dispositif pour retourner à l'état de repos est identique à celui décrit ci-dessus, à la seule différence près que, sous l'effet conjugué du rappel élastique de la lame 75, vers le plot 78 et du jeu de l'ergot 31 dans l'encoche 62, l'interrupteur 70 est, à un instant du parcours BA du pignon 40, ramené brutalement à sa position initiale.The process performed by the device to return to the rest state is identical to that described above, with the only difference that, under the combined effect of the elastic return of the blade 75, towards the pad 78 and the play of the lug 31 in the notch 62, the switch 70 is, at an instant in the path BA of the pinion 40, suddenly returned to its initial position.

Selon un deuxième mode de mise en oeuvre de l'invention, le moteur 400 d'entraînement pas à pas du bloc-cames 600 est alimenté par l'intermédiaire de l'interrupteur 70.
Plus précisément, le moteur 400 d'entraînement pas à pas est relié au plot 79 de l'interrupteur 70, le plot 77 étant relié à la tension de source 960 (les liaisons étant représentées en tirets sur les figures) Lorsque le dispositif de l'invention est au repos, c'est à dire lorsque le bloc-cames 600 est en rotation pas à pas, le moteur 400 d'entraînement pas à pas est alors alimenté par l'intermédiaire du plot 77 et de la lame 80.
Lorsque le dispositif de l'invention est actif, c'est à dire lorsque le bloc-cames 600 est entraîné par le moteur 500 d'entraînement rapide, le moteur 400 d'entraînement pas à pas est alors alimenté par l'intermédiaire du plot 76, de la lame 75, et de la lame 80, ces deux lames étant alors en contact, à mi-distance des plots 77 et 78.
Ainsi, selon cet autre mode de mise en oeuvre de l'invention, le moteur d'entraînement pas à pas est aussi alimenté en permanence, à l'exception de périodes de transition du dispositif d'une position vers une autre, pendant lesquelles les lames 75 et 80 franchissent la distance les séparant. En effet, pendant ces instants, aucun contact n'est réalisé par la lame 80 avec l'un des deux plots 76 ou 77. Ces périodes de transition correspondent aux déplacements du pignon 40 de la position A vers la position B, ou de la position B vers la position A.According to a second embodiment of the invention, the motor 400 for stepping drive of the cam block 600 is supplied via the switch 70.
More specifically, the stepping drive motor 400 is connected to the pad 79 of the switch 70, the pad 77 being connected to the source voltage 960 (the connections being shown in dashes in the figures) When the device of the The invention is at rest, that is to say when the cam block 600 is rotating step by step, the stepping drive motor 400 is then supplied by means of the pad 77 and the blade 80.
When the device of the invention is active, that is to say when the cam block 600 is driven by the fast drive motor 500, the stepping drive motor 400 is then supplied via the stud 76, of the blade 75, and of the blade 80, these two blades then being in contact, midway between the pads 77 and 78.
Thus, according to this other embodiment of the invention, the stepping drive motor is also continuously supplied, at with the exception of periods of transition of the device from one position to another, during which the blades 75 and 80 cross the distance separating them. In fact, during these moments, no contact is made by the blade 80 with one of the two studs 76 or 77. These transition periods correspond to the movements of the pinion 40 from position A to position B, or from the position B to position A.

Il convient de vérifier que l'arrêt du moteur 400 d'entraînement pas à pas pendant ces périodes de transition, qui signifie l'arrêt de la rotation de la roue 12, n'altère pas le fonctionnement du dispositif de l'invention :

  • lorsque le pignon parcourt l'arc AB, l'arrêt de la roue 12 se produit lorsque l'ergot 31 de la bascule 30, après avoir franchi la longueur ou jeu, de l'encoche 60, transmet la rotation de la bascule 30 à la came 60, qui agit alors sur les lames 75 et 80, par l'intermédiaire du levier 71.
    L'arrêt de la roue 12 a pour effet d'augmenter la vitesse différentielle entre les deux roues 12 et 13, le pignon 40 subit alors une accélération de son mouvement et atteint le point B plus rapidement que lors du premier mode de mise en oeuvre de l'invention, décrit précédemment.
    En B, le contact est établi entre le plot 79 et le plot 76, et la tension de source est à nouveau délivrée au moteur d'entraînement pas à pas, cette situation étant commune aux deux modes de mise en oeuvre de l'invention.
  • Lors du retour du pignon 40 vers la position A, la roue 23 est arrêtée et seule la roue 12 assure l'entraînement du pignon 40 vers la position A.
    Le retour brutal de l'interrupteur 70 à sa position initiale se produit dès l'instant où le plateau 165 de la came 60 s'efface sous l'excroissance 73 du levier 71, car la lame 80, sous l'effet de son propre rappel élastique, passe alors de la position de contact avec la lame 75 à la position de contact avec le plot 77.
    La rotation de la roue 12 n'est donc pratiquement pas interrompue, et le pignon 40 achève sa course vers le point A.
It should be checked that the stopping of the stepping drive motor 400 during these transition periods, which signifies the stopping of the rotation of the wheel 12, does not alter the operation of the device of the invention:
  • when the pinion traverses the arc AB, the wheel 12 stops when the lug 31 of the rocker 30, after having crossed the length or clearance, of the notch 60, transmits the rotation of the rocker 30 to the cam 60, which then acts on the blades 75 and 80, by means of the lever 71.
    The stopping of the wheel 12 has the effect of increasing the differential speed between the two wheels 12 and 13, the pinion 40 then undergoes an acceleration of its movement and reaches point B more quickly than during the first mode of implementation. of the invention, described above.
    In B, the contact is established between the pad 79 and the pad 76, and the source voltage is again supplied to the stepping drive motor, this situation being common to the two embodiments of the invention.
  • When the pinion 40 returns to position A, the wheel 23 is stopped and only the wheel 12 ensures the drive of the pinion 40 to position A.
    The sudden return of the switch 70 to its initial position occurs as soon as the plate 165 of the cam 60 disappears under the projection 73 of the lever 71, because the blade 80, under the effect of its own elastic return, then passes from the position of contact with the blade 75 to the position of contact with the pad 77.
    The rotation of the wheel 12 is therefore practically not interrupted, and the pinion 40 completes its race towards the point A.

On notera que le jeu de l'ergot 31 dans l'encoche 62 de la came 60 est essentiel au fonctionnement du dispositif de l'invention selon cet autre mode de mise en oeuvre.
En effet, en l'absence d'un tel jeu, la lame 80 serait maintenue dans une position intermédiaire lors de l'arrêt de la roue 12, à un instant du parcours BA du pignon 40, et le dispositif complet serait définitivement bloqué. Le débattement entre la came 60 et la bascule 30 doit donc être suffisant pour assurer le libre retour de la lame 80 jusqu'à sa position de contact avec le plot 77.It will be noted that the play of the lug 31 in the notch 62 of the cam 60 is essential for the operation of the device of the invention according to this other embodiment.
Indeed, in the absence of such a game, the blade 80 would be maintained in an intermediate position when the wheel 12 stops, at an instant in the path BA of the pinion 40, and the complete device would be definitively blocked. The clearance between the cam 60 and the rocker 30 must therefore be sufficient to ensure the free return of the blade 80 to its position of contact with the stud 77.

Ce deuxième mode de mise en oeuvre de l'invention permet dans certains cas de simplifier le réseau des lignes éléctriques à l'intérieur du programmateur 300.This second embodiment of the invention makes it possible in certain cases to simplify the network of electrical lines inside the programmer 300.

On notera que la roue 12 ne joue pas de rôle dans le groupe réducteur 100, et n'a été rajoutée ici que pour permettre l'implantation du dispositif de l'invention dans un programmateur déjà existant, selon une forme de réalisation particulière. En effet, on pourait tout à fait envisager d'utiliser la roue 10 du groupe réducteur 100 pour coopérer avec le pignon 40, si les contraintes d'implantation des éléments le permettaient.
De la même façon, on pourrait aussi rajouter une roue supplémentaire associée au groupe 200 et lui faire jouer le rôle que joue la roue 23, dans le dispositif de l'invention ci-décrit, si les contraintes d'implantation l'exigeaient.It will be noted that the wheel 12 does not play a role in the reduction unit 100, and has only been added here to allow the installation of the device of the invention in an already existing programmer, according to a particular embodiment. Indeed, one could completely consider using the wheel 10 of the reduction unit 100 to cooperate with the pinion 40, if the constraints of implantation of the elements allow it.
In the same way, one could also add an additional wheel associated with the group 200 and make it play the role played by the wheel 23, in the device of the invention described below, if the layout constraints required it.

Le dispositif de l'invention est applicable à tout programmateur comportant deux chaînes cinématiques d'entraînement du bloc-cames, indépendantes ou distinctes, l'une étant dédiée à l'entraînement pas à pas, l'autre étant dédiée à l'entraînement rapide.The device of the invention is applicable to any programmer comprising two kinematic chains for driving the cam block, independent or separate, one being dedicated to stepping drive, the other being dedicated to fast driving .

Avantageusement, le dispositif de l'invention peut être adapté rapidement sur un programmateur existant, sans entraîner des modifications majeures sur les éléments constituant ledit programmateur.Advantageously, the device of the invention can be quickly adapted to an existing programmer, without causing major modifications to the elements constituting said programmer.
