Description

La présente invention concerne une installation de remplissage de récipients par un produit tel qu'un produit liquide, semi liquide, pâteux... et par exemple utilisable pour la mise en boîtes de conserve de produits alimentaires.The present invention relates to an installation for filling containers with a product such as a liquid product, semi liquid, pasty ... and for example usable for the canning of food products.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Une installation de remplissage comprend généralement un bâti fixe sur lequel sont montés un plateau support de récipients, fixe en hauteur par rapport au bâti, et un équipage rotatif pivotant selon un axe perpendiculaire au plateau support. L'équipage rotatif comporte un organe de convoyage des récipients supportés et un ensemble de remplissage qui surmonte le plateau support et qui est fixe en rotation par rapport à l'organe de convoyage. L'organe de convoyage définit des emplacements de récipients et l'ensemble de remplissage comporte une cuve de produit pourvue à l'aplomb de chaque emplacement de récipient d'un organe de distribution de doses de produit destiné à s'étendre juste au-dessus de l'ouverture du récipient afin de limiter le risque que du produit s'écoule à l'extérieur du récipient.A filling installation generally comprises a fixed frame on which are mounted a container support plate, fixed in height relative to the frame, and a rotary assembly pivoting along an axis perpendicular to the support plate. The rotary equipment comprises a conveying member of the supported containers and a filling assembly which overcomes the support plate and which is fixed in rotation with respect to the conveying member. The conveying member defines receptacle locations and the refilling assembly comprises a product vat provided vertically above each receptacle location of a product dose dispensing member intended to extend just above it. opening of the container to limit the risk of product flowing out of the container.

Lorsque l'installation est destinée au remplissage de séries de récipients de hauteurs différentes, l'installation comporte en outre un dispositif de réglage en hauteur de l'ensemble de remplissage par rapport au plateau support pour adapter la hauteur des organes de distribution à celles des récipients de la série à remplir. Ce dispositif de réglage comporte généralement un vérin hydraulique reliant l'ensemble de remplissage au bâti de telle manière que la hauteur de l'ensemble de remplissage par rapport au plateau support soit réglée en sortant ou en rentrant plus ou moins la tige du vérin. Le vérin a une section relativement importante pour pouvoir supporter le poids de l'ensemble de remplissage. En outre, la reprise de ces efforts suppose que le bâti comporte une structure adaptée pour supporter le corps du vérin, ce qui augmente l'encombrement axial de l'installation déjà important du fait de la longueur du corps du vérin.When the installation is intended for filling series of containers of different heights, the installation further comprises a device for adjusting the height of the filling assembly relative to the support plate to adjust the height of the dispensing members to those of containers of the series to fill. This adjusting device generally comprises a hydraulic cylinder connecting the filling assembly to the frame in such a way that the height of the filling assembly relative to the support plate is adjusted by leaving or re-entering more or less the rod of the jack. The cylinder has a relatively large section to support the weight of the filling assembly. In addition, the resumption of these efforts supposes that buildings a structure adapted to support the body of the cylinder, which increases the axial size of the installation already important because of the length of the cylinder body.

Par ailleurs, les organes de distribution de doses de produit sont généralement actionnés par des cames solidaires du bâti. Le réglage en hauteur de l'ensemble de remplissage oblige à régler également en hauteur les cames. L'utilisation d'un vérin hydraulique rend difficile un réglage simultané de la hauteur des cames. Il en résulte l'obligation d'effectuer ces réglages de façon séparée, ce qui augmente le temps de réglage et accroît également le risque d'une erreur de réglage.Moreover, the product dose distribution members are generally actuated by cams secured to the frame. The height adjustment of the filling assembly also makes it necessary to adjust the cams in height. The use of a hydraulic cylinder makes it difficult to simultaneously adjust the height of the cams. This results in the need to make these adjustments separately, which increases the adjustment time and also increases the risk of a setting error.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Il serait donc intéressant de disposer d'un moyen simple, économique et efficace pour régler en hauteur une installation de remplissage de récipients.It would therefore be interesting to have a simple, economical and effective way to adjust height a container filling installation.

Les récipients 201, 202 se distinguent l'un de l'autre notamment par leurs hauteurs différentes. Bien que les récipients 201, 202 soient représentés simultanément sur l'installation aux fins de la description qui suit, il va de soi que, normalement, lors du remplissage d'une série de récipients, tous les récipients de la série ont sensiblement la même hauteur.With reference to the figures, the filling installation according to the invention is arranged to ensure the filling of at least two types of containers 201, 202 with a product, such as a food product. The containers 201, 202 are distinguished from each other in particular by their different heights. Although the containers 201, 202 are simultaneously represented on the installation for the purposes of the description which follows, it goes without saying that, normally, when filling a series of containers, all the containers of the series have substantially the same height.

L'installation comprend un bâti fixe généralement désigné en 1 sur lequel sont montés un plateau support 2 de récipients et un équipage rotatif généralement désigné en 3.The installation comprises a fixed frame generally designated 1 on which are mounted a support plate 2 of containers and a rotary assembly generally designated 3.

L'ensemble de remplissage 7 est fixe en rotation par rapport à l'organe de convoyage 6 et comporte une cuve de produit 9 pourvue à l'aplomb de chaque alvéole 8 d'un organe de distribution de doses de produit généralement désigné en 10.The filling assembly 7 is fixed in rotation with respect to the conveying member 6 and comprises a product tank 9 provided at the base of each cell 8 of a product dose distribution member generally designated 10.

Chaque organe de distribution 10 comprend un cylindre 11 qui reçoit un piston doseur 12 à coulissement selon une direction parallèle à l'axe 5 et qui est relié à la cuve 9 par une vanne 13 à trois voies incorporant un boisseau 14 pivotant autour d'un axe sensiblement perpendiculaire à l'axe 5 entre une position de dosage dans laquelle le boisseau 14 assure la liaison du cylindre 11 avec la cuve de produit 9 et une position de distribution dans laquelle le boisseau 14 assure la liaison du cylindre 11 avec un bec de distribution 15 s'étendant en regard de l'alvéole 8 correspondante.Each dispensing member 10 comprises a cylinder 11 which receives a measuring piston 12 sliding in a direction parallel to the axis 5 and which is connected to the tank 9 by a three-way valve 13 incorporating a valve 14 pivoting around a axis substantially perpendicular to the axis 5 between a metering position in which the plug 14 ensures the connection of the cylinder 11 with the product tank 9 and a dispensing position in which the plug 14 ensures the connection of the cylinder 11 with a spout distribution 15 extending opposite the corresponding cell 8.

L'ensemble de liaison 4 reliant l'équipage rotatif 3 au bâti 1 comprend un manchon fixe 16, solidaire du bâti et centré sur l'axe 5, qui reçoit à pivotement un manchon support 17 ayant une extrémité supérieure équipée de l'organe de convoyage 6 et une extrémité inférieure qui, d'une part, reçoit à coulissement un manchon intermédiaire 18 extérieurement fileté et qui, d'autre part, est pourvue d'un écrou 19. L'écrou 19 est monté sur l'extrémité inférieure du manchon support 17 pour être fixe en translation et libre en rotation par rapport au manchon support 17 et est engagé sur le manchon intermédiaire 18. Le manchon intermédiaire 18 a une extrémité inférieure en saillie du manchon fixe 16 et du manchon support 17 pour être reçue à coulissement dans le bâti 1 et une extrémité supérieure sur laquelle est en butée une extrémité inférieure d'un coulisseau 20 reçu à coulissement parallèlement à l'axe 5 dans le manchon support 17 et dont une extrémité supérieure porte l'ensemble de remplissage 7. Le manchon intermédiaire 18 est immobilisé en rotation par rapport au bâti 1 par l'intermédiaire de clavettes 35 solidaires du bâti 1 et reçues à coulissement dans des rainures longitudinales 36 du manchon intermédiaire 18.

Il va de soi que les paliers ci-dessus énumérés peuvent être de types différents de ceux mentionnés. On notera que l'équipage rotatif 3 est supporté par le manchon fixe qui est seul rigidement fixé au bâti 1. Ceci facilite le montage de l'équipage rotatif 3 par rapport au bâti 1 et permet d'avoir un bâti 1 compact.The link assembly 4 connecting the rotary crew 3 to the frame 1 comprises a fixed sleeve 16, integral with the frame and centered on the axis 5, which pivotally receives a support sleeve 17 having an upper end equipped with the conveying member 6 and a lower end which, of a on the other hand, is provided with a nut 19.

The intermediate sleeve 18 has a lower end projecting from the fixed sleeve 16 and the support sleeve 17 to be slidably received in the frame 1 and an upper end on which abuts a lower end of a slider 20 slidably received parallel to the axis 5 in the support sleeve 17 and whose upper end carries the filling assembly 7. The intermediate sleeve 18 is immobilized in rotation relative to the frame 1 by means of keys 35 integral with the frame 1 and slidably received in longitudinal grooves 36 of the intermediate sleeve 18. The slide 20 is immobilized in rotation with respect to the support sleeve 17 via keys 37 integral with the support sleeve 17 and slidably received in longitudinal grooves 38 of the slider 20. The axial forces supported by the slider 20, and in particular the weight of the filler assembly 7, are transmitted to the intermediate sleeve 18 by a roller stop 39, then to the nut 19 by the thread of the intermediate sleeve 18, then to the support sleeve 17 by a ball stop 40 disposed between the nut 19 and a connecting bell 41 secured to the support sleeve 17, then to the fixed sleeve 16 and to the frame 1 by two tapered roller bearings 42 arranged in O. It goes without saying that the bearings above enumerated can be from types different from those mentioned. Note that the rotating assembly 3 is supported by the fixed sleeve which is only rigidly fixed to the frame 1. This facilitates the mounting of the rotating assembly 3 relative to the frame 1 and allows to have a compact frame 1.

L'écrou 19 et le manchon intermédiaire 18 forment respectivement un premier élément et un deuxième élément d'une liaison vis / écrou d'un dispositif, généralement désigné en 21, de réglage en hauteur de l'ensemble de remplissage 7 par rapport au plateau support 2.
