Description

La présente invention est relative à une boîte de vitesse destinée à équiper un batteur-mélangeur.The present invention relates to a gearbox for equipping a mixer-mixer.

Les batteurs-mélangeurs sont utilisés dans l'industrie alimentaire, notamment dans les domaines de la boulangerie et de la pâtisserie pour la fabrication de pâtes et crèmes.Mixer-mixers are used in the food industry, particularly in the fields of baking and pastry making for pasta and cream.

Les batteurs-mélangeurs comportent classiquement un support présentant une colonne porteuse, une partie supérieure horizontale ainsi qu'une partie inférieure, les parties supérieure et inférieure étant adjacentes à la colonne porteuse. Une cuve contenant la matière à mélanger est alors disposée entre la partie inférieure et la partie supérieure horizontale du support.The mixer-mixers conventionally comprise a support having a carrier column, a horizontal upper part and a lower part, the upper and lower parts being adjacent to the carrier column. A tank containing the material to be mixed is then disposed between the lower part and the upper horizontal part of the support.

Les batteurs-mélangeurs comportent en outre une boîte de vitesse motorisée destinée à entraîner au moins un outil de mélange dans la cuve. Une boîte de vitesse pour batteur-mélangeur comprend typiquement une couronne, un pignon planétaire et au moins un pignon satellite. La couronne est un pignon à denture interne, monté fixe sur le support.The mixer-mixers further include a motorized gearbox for driving at least one mixing tool into the tank. A gearbox for a mixer-mixer typically comprises a ring gear, a sun gear and at least one planet gear. The crown is a pinion with internal teeth, fixedly mounted on the support.

Le terme «planétaire» désigne un pignon dont l'axe de rotation est immobile. Le terme «satellite» désigne, quant à lui, un pignon dont l'axe de rotation propre est en révolution autour de l'axe de rotation du pignon planétaire.The term "planetary" designates a pinion whose axis of rotation is stationary. The term "satellite" means, meanwhile, a pinion whose own axis of rotation is in revolution about the axis of rotation of the sun gear.

Dans l'état de la technique, le pignon planétaire est monté sur un arbre moteur tandis que le pignon satellite est monté pivotant sur un corps dénommé porte-satellite. Le pignon satellite s'engrène à la fois sur le pignon planétaire et sur la couronne. Enfin, l'outil de mélange est monté sur l'arbre du pignon satellite.In the state of the art, the sun gear is mounted on a motor shaft while the planet gear is pivotally mounted on a body called the planet carrier. The planet gear meshes with both the sun gear and the crown. Finally, the mixing tool is mounted on the shaft of the satellite gear.

L'entraînement de l'outil de mélange dans la cuve est effectué par l'arbre moteur. En effet, l'arbre moteur du planétaire entraîne la rotation propre du pignon satellite. L'engrenage du pignon satellite sur la couronne permet alors la révolution du pignon satellite autour du pignon planétaire. Il en résulte un mouvement de rotation propre et de révolution autour du planétaire de l'outil de mélange dans la cuve.The drive of the mixing tool in the tank is carried out by the motor shaft. Indeed, the driving shaft of the sun gear causes the own rotation of the planet gear. The gear of the planet gear on the crown then allows the revolution of the planet gear around the planet gear. This results in a clean rotational movement and revolution around the sun gear of the mixing tool in the tank.

A cet regard, le document FR2844442 décrit un système de boîte de vitesse à train épicycloïdal impliquant plusieurs satellites afin d'entraîner plusieurs outils de mélange. Un tel système de boîte de vitesse présente plusieurs inconvénients.In this regard, the document FR2844442 describes an epicyclic gearbox system involving multiple satellites to drive several mixing tools. Such a gearbox system has several disadvantages.

L'inconvénient majeur réside dans le volume important occupé par le système de boîte de vitesse dans la partie supérieure horizontale du support. Ce volume important est essentiellement dû à la présence de l'arbre moteur entraînant le pignon planétaire. De surcroît, le moteur de la boîte de vitesse est intégré à la partie supérieure de la colonne porteuse du support. Il résulte ainsi de cet aménagement du moteur et du système de boîte de vitesse un fort encombrement axial. On entendra dans le cadre de la présente description par «axial» la direction de la colonne porteuse du support, c'est-à-dire la direction sensiblement verticale.The major disadvantage lies in the large volume occupied by the gearbox system in the upper horizontal part of the support. This large volume is mainly due to the presence of the motor shaft driving the sun gear. In addition, the gearbox motor is integrated in the upper part of the support column of the support. It thus results from this arrangement of the engine and the gearbox system a large axial size. In the context of the present description, the term "axial" will be understood to mean the direction of the support column of the support, that is to say the substantially vertical direction.

Cet encombrement axial conduit à un empiètement de la boîte de vitesse sur le volume de la cuve, la boîte de vitesse créant par là-même un couloir annulaire avec la cuve. Ce couloir annulaire ne permet donc pas d'introduire la matière à mélanger par le dessus de la boîte de vitesse. La zone d'introduction est par conséquent ménagée latéralement à la boîte de vitesse, pouvant entraîner alors à un bourrage de la matière à mélanger dans la zone du couloir annulaire.This axial size leads to an encroachment of the gearbox on the volume of the tank, the gearbox thereby creating an annular passage with the tank. This annular passageway therefore does not allow to introduce the material to be mixed by the top of the gearbox. The introduction zone is therefore arranged laterally to the gearbox, which can then lead to a jamming of the material to be mixed in the zone of the annular passage.

Le pignon planétaire et les pignons satellites se trouvent ainsi disposés dans la zone d'introduction de la matière à mélanger. Cette disposition des pignons planétaire et satellite, conjuguée avec le fort encombrement axial, rend alors extrêmement difficile l'accès au nettoyage du système de boîte de vitesse.The planet gear and the planet gears are thus arranged in the zone of introduction of the material to be mixed. This arrangement of planet and satellite gears, combined with the high axial size, makes it extremely difficult access to the cleaning of the gearbox system.

Enfin, l'encombrement axial est tel qu'il est difficile d'envisager l'utilisation d'un second moteur pour la boîte de vitesse sans exacerber les inconvénients cités précédemment. Or, un second moteur actionnant les pignons satellites soit directement, soit via le porte-satellites, permet d'accroître la gamme de vitesses et la gamme de rapports de transmission de la boîte de vitesse. Ainsi, cette modularité de rapports de transmission est difficilement disponible pour les systèmes de boîtes de vitesse de l'état de la technique.Finally, the axial size is such that it is difficult to envisage the use of a second motor for the gearbox without exacerbating the disadvantages mentioned above. Now, a second motor driving the planet gears either directly or via the planet carrier, makes it possible to increase the speed range and the range of transmission ratios of the gearbox. Thus, this transmission ratio modularity is hardly available for gearbox systems of the state of the art.

La présente invention a pour objet de remédier en tout ou partie aux inconvénients précités et consiste à cet effet en une boîte de vitesse pour batteur-mélangeur comprenant un pignon planétaire, un porte-satellite comportant un corps délimitant une enceinte, au moins un pignon satellite, muni d'une denture externe, et monté pivotant sur le porte-satellite, ledit pignon satellite s'engrenant avec le pignon planétaire, et caractérisée en ce que le corps du porte-satellite est conformé pour coopérer avec un organe d'entraînement de manière à ce que ledit organe d'entraînement entraîne en rotation ledit porte-satellite.The object of the present invention is to remedy all or part of the aforementioned drawbacks and to this end consists of a gearbox for a mixer-mixer comprising a sun gear, a planet carrier comprising a body delimiting an enclosure, at least one satellite pinion. , provided with an external toothing, and pivotally mounted on the planet carrier, said planet gear meshing with the sun gear, and characterized in that the The body of the carrier is shaped to cooperate with a drive member so that said drive member rotates said carrier.

Ainsi, la boîte de vitesse selon la présente invention est conçue pour que le porte-satellite puisse être entraîné par un moteur: ceci permet de s'affranchir de l'arbre moteur présent dans l'état de la technique. En effet, selon la présente invention, la rotation propre du pignon satellite est initiée directement par la rotation du porte-satellite. Par conséquent, la suppression de l'arbre moteur du pignon planétaire réduit fortement l'encombrement axial dans la partie supérieure horizontale du support.Thus, the gearbox according to the present invention is designed so that the carrier can be driven by a motor: this makes it possible to overcome the motor shaft present in the state of the art. Indeed, according to the present invention, the own rotation of the planet pinion is initiated directly by the rotation of the planet carrier. Therefore, the removal of the drive shaft of the sun gear greatly reduces the axial space in the upper horizontal part of the support.

Dans un mode de réalisation de la présente invention, le pignon planétaire présente une couronne périphérique montée fixe, munie d'une denture interne. La couronne périphérique fixe permet la révolution du porte-satellite autour du centre de la cuve.In one embodiment of the present invention, the sun gear has a fixed mounted peripheral ring provided with an internal toothing. The fixed peripheral ring allows the revolution of the planet carrier around the center of the tank.

Selon un autre mode de réalisation de l'invention, le pignon planétaire, muni d'une denture externe, est monté sur un arbre moteur. Comme dans le mode de réalisation précédent, le pignon planétaire permet la révolution du porte-satellite autour du centre de la cuve. Dans cette configuration à deux moteurs, l'ajout d'un pignon planétaire motorisé permet d'ajuster le rapport de transmission de la boîte de vitesse. L'encombrement axial dû à l'arbre moteur du pignon planétaire est réduit par rapport à une boîte de vitesse de l'état de la technique qui comporterait deux moteurs.According to another embodiment of the invention, the sun gear, provided with an external toothing, is mounted on a motor shaft. As in the previous embodiment, the sun gear allows the revolution of the planet carrier around the center of the tank. In this two-motor configuration, the addition of a motorized sun gear makes it possible to adjust the transmission ratio of the gearbox. The axial size due to the drive shaft of the sun gear is reduced compared to a gearbox of the state of the art which would include two motors.

Avantageusement, le pignon planétaire et le pignon satellite sont ménagés à l'intérieur de l'enceinte du porte-satellite. Ainsi, le pignon planétaire et le pignon satellite se trouvent encapsulés dans le corps du porte-satellite de telle sorte qu'ils n'interfèrent plus dans la zone d'introduction de la matière à mélanger, libérant ainsi l'accès au nettoyage des pièces mécaniques.Advantageously, the sun gear and the sun gear are arranged inside the enclosure of the planet carrier. Thus, the sun gear and the planet pinion are encapsulated in the body of the planet carrier so that they no longer interfere with the zone of introduction of the material to be mixed, thus freeing access to the cleaning of the parts. mechanical.

Selon une caractéristique, le porte-satellite comporte un corps de poulie comprenant une gorge de guidage et de logement d'une courroie d'entraînement. Cet aménagement permet d'entraîner le porte-satellite en rotation par la courroie d'entraînement.According to one feature, the carrier comprises a pulley body comprising a guide groove and housing of a drive belt. This arrangement makes it possible to drive the planet carrier in rotation by the drive belt.

La présente invention se rapporte également à un dispositif pour batteur-mélangeur comportant une boîte de vitesse conforme à l'invention et un organe d'entraînement conçu pour entraîner en rotation le porte-satellite de la boîte de vitesse conforme à l'invention.The present invention also relates to a device for a mixer-mixer comprising a gearbox according to the invention and a drive member designed to drive in rotation the planet carrier of the gearbox according to the invention.

Selon une caractéristique, l'organe d'entraînement comporte une courroie d'entraînement.According to one characteristic, the drive member comprises a drive belt.

Enfin, la présente invention concerne également un batteur-mélangeur comprenant au moins un outil de mélange et des premiers moyens de motorisation, équipé d'un dispositif conforme à l'invention, ledit dispositif assurant la liaison cinématique entre l'outil de mélange et les premiers moyens de motorisation de manière à ce que les premiers moyens de motorisation sont reliés à l'organe d'entraînement du dispositif et l'outil de mélange est relié au pignon satellite.Finally, the present invention also relates to a mixer-mixer comprising at least one mixing tool and first motorization means, equipped with a device according to the invention, said device ensuring the kinematic connection between the mixing tool and the first motorization means so that the first motorization means are connected to the drive member of the device and the mixing tool is connected to the planet gear.

Préférentiellement, ledit batteur mélangeur comprend en outre des seconds moyens de motorisation reliés à l'arbre moteur du pignon planétaire de telle sorte que les premiers et seconds moyens de motorisation actionnent respectivement le porte-satellite par l'organe d'entraînement et le pignon planétaire par son arbre moteur.Preferably, said mixing beater further comprises second drive means connected to the drive shaft of the sun gear so that the first and second drive means respectively actuate the carrier by the drive member and the sun gear. by its motor shaft.

Selon une caractéristique, le batteur-mélangeur comprend en outre une cuve au-dessus de laquelle sont ménagés des moyens d'introduction de la matière à mélanger, de manière adjacente au corps du porte-satellite. Ainsi, l'introduction de la matière à mélanger peut être réalisée de manière optimale, c'est-à-dire par gravité, puisque la boîte de vitesse n'obstrue pas le passage de la matière à mélanger.According to one characteristic, the mixer-mixer further comprises a tank above which are provided means for introducing the material to be mixed, adjacent the body of the carrier. Thus, the introduction of the material to be mixed can be carried out optimally, that is to say by gravity, since the gearbox does not obstruct the passage of the material to be mixed.

La première poulie motrice 9 et la seconde poulie motrice 10 entraînent respectivement le porte-satellite 7 et la poulie d'entraînement 13 -et donc l'arbre moteur 8-. Il en résulte respectivement l'actionnement du pignon satellite 6 et du pignon planétaire 5. Le pignon satellite 6 est donc à la fois actionné directement par le porte-satellite 7 et par l'engrenage avec le pignon planétaire 5. Par voie de conséquence, l'outil de mélange monté sur l'arbre 3 est entraîné à la fois autour de son axe propre et en révolution autour du pignon planétaire 5. La motorisation du pignon planétaire 5 permet d'ajuster le rapport de transmission de la boîte de vitesse.The first drive pulley 9 and the second drive pulley 10 respectively drive the planet carrier 7 and the drive pulley 13-and thus the drive shaft 8-. This results respectively in the operation of the planet pinion 6 and the sun gear 5. The planet pinion 6 is therefore both actuated directly by the planet carrier 7 and the gear with the sun gear 5. As a consequence, the mixing tool mounted on the shaft 3 is driven both around its own axis and in revolution around the sun gear 5. The motorization of the sun gear 5 makes it possible to adjust the transmission ratio of the gearbox.

La boîte de vitesse peut également fonctionner avec un pignon planétaire 5 monté fixe, ce qui est l'objet d'un autre mode de réalisation, illustré par le schéma symbolique de la figure 4.The gearbox can also operate with a fixed mounted planetary gear 5, which is the object of another embodiment, illustrated by the symbolic diagram of the figure 4 .

Dans ce mode de réalisation, le pignon planétaire 5 présente une couronne périphérique à denture interne, montée fixe sur le support 4. Sur la figure 4, le pignon planétaire 5 est situé à l'extérieur de l'enceinte du porte-satellite 7. Toutefois, il est également possible de ménager le pignon planétaire à l'intérieur de l'enceinte du porte-satellite 7, ce pignon interne présentant alors une denture externe comme dans le mode de réalisation des figures 1 à 3.In this embodiment, the sun gear 5 has a ring gear with internal teeth, fixedly mounted on the support 4. On the figure 4 , the sun gear 5 is located outside the chamber of the planet carrier 7. However, it is also possible to arrange the sun gear inside the chamber of the planet carrier 7, this internal pinion having then an external toothing as in the embodiment of Figures 1 to 3 .

La première poulie motrice 9 entraîne en rotation le porte-satellite 7 au moyen de la courroie d'entraînement 15. Ainsi, le pignon satellite 6 est actionné et vient s'engrener sur la couronne périphérique du pignon planétaire 5 si bien que l'outil de mélange, monté sur l'arbre 3, est entraîné à la fois autour de son axe propre et en révolution autour de la couronne périphérique du pignon planétaire 5.The first driving pulley 9 rotates the planet carrier 7 by means of the drive belt 15. Thus, the planet pinion 6 is actuated and meshes with the peripheral ring gear of the sun gear 5 so that the tool mixture, mounted on the shaft 3, is driven both around its own axis and in revolution around the peripheral ring of the sun gear 5.

Bien entendu, l'exemple de réalisation évoqué ci-dessus ne présente aucun caractère limitatif, et d'autres détails et améliorations peuvent être apportés au dispositif selon l'invention, sans pour autant sortir du cadre de l'invention où d'autres formes du dispositif peuvent être réalisées.Of course, the exemplary embodiment mentioned above has no limiting character, and other details and improvements can be made to the device according to the invention, without departing from the scope of the invention where other forms of the device can be realized.
