Description

Dispositif de dosage pondéral, notamment pour produit pâteux ou hétérogène. Weight metering device, especially for pasty or heterogeneous product.
La présente invention concerne un dispositif de dosage pondéral, en particulier pour des produits pâteux ou hétérogènes.The present invention relates to a weight metering device, in particular for pasty or heterogeneous products.
On connaît du document FR-2.555.132 un dispositif de dosage pondéral comportant un bec de remplissage associé à un conduit d'alimentation et disposé à l'aplomb d'un organe de pesage relié au bec de remplissage pour commander une ouverture et une fermeture du bec de remplissage, et un organe de poussée disposé en amont du bec de remplissage par référence à un sens d'écoulement de produit, cet organe de poussée comportant un piston disposé dans un cylindre et associé à une vanne trois voies mettant la chambre de pompage balayée par le piston alternativement en relation avec une trémie d'alimentation et avec un orifice de distribution de produit du bec de remplissage.Document FR-2,555,132 discloses a weight metering device comprising a filling spout associated with a supply duct and disposed directly above a weighing member connected to the filling spout to control opening and closing of the filling spout, and a thrust member arranged upstream of the filling spout with reference to a direction of flow of product, this thrust member comprising a piston placed in a cylinder and associated with a three-way valve placing the pumping swept by the piston alternately in relation to a feed hopper and with a product distribution orifice of the filling spout.
Un inconvénient de ce dispositif est la difficulté de nettoyer toutes les pièces en mouvement principalement dans le cas de produits alimentaires. Un autre inconvénient est le risgue de détérioration physique de la texture du produit en raison des passages répétés du produit dans les orifices de la vanne trois voies lors des mouvements d'aspi¬ ration et de refoulement du produit, surtout s'il s'agit d'un produit fragile.A disadvantage of this device is the difficulty of cleaning all the moving parts mainly in the case of food products. Another disadvantage is the risk of physical deterioration of the texture of the product due to repeated passages of the product in the orifices of the three-way valve during movements of suction and discharge of the product, especially if it is of a fragile product.
Selon l'invention on propose un dispositif de dosage pondéral du type précité dans lequel l'organe de poussée comporte une vis montée pour tourner dans un carter et reliée à un moteur d'entraînement commandé en rotation par l'organe de pesage.According to the invention there is provided a weight metering device of the aforementioned type in which the thrust member comprises a screw mounted to rotate in a casing and connected to a drive motor controlled in rotation by the weighing member.
Ainsi le produit est poussé en douceur par la vis lors de la rotation de celle-ci et n'est amenée à passer qu'une seule fois dans les orifices du bec de remplissage de sorte que sa texture est faiblement altérée par le dispositif même lorsqu'il s'agit d'un produit fragile. En outre, en raison du mouvement continu de 1 ' écoulement le nettoyage et la stérilisation du dispositif selon l'invention sont obtenus particulièrement aisément en introduisant de la vapeur ou de l'eau surpressée dans le circuit de distribution sans qu'il soit nécessaire de prévoir un cycle particulier.Thus the product is gently pushed by the screw during its rotation and is only caused to pass once through the orifices of the filling spout so that its texture is slightly altered by the device even when 'It is a fragile product. In addition, due to the continuous movement of the flow, the cleaning and sterilization of the device according to the invention are obtained. particularly easily by introducing steam or pressurized water into the distribution circuit without the need for a particular cycle.
Selon une version avantageuse de l'invention, le bec de remplissage comporte un orifice d'entrée accouplée au carter de l'organe de poussée et un organe de fermeture se déplaçant perpendiculairement à une direction de 1'écoulement dans l'orifice d'entrée de façon à avoir un effet de cisail¬ lement de 1'écoulement lors de la fermeture de 1'orifice d'entrée. Ainsi, dans le cas d'un produit hétérogène, un morceau de matière se présentant dans le bec de remplissage au moment de la fermeture est sectionné par 1'organe de fermeture et l'on obtient ainsi une très grande précision du poids de produit introduit dans le récipient. De préférence, l'orifice d'entrée du bec de remplissage est disposé selon un axe parallèle à la vis de l'organe de poussée. Ainsi on minimise le risque de détério¬ ration physique de la texture du produit.According to an advantageous version of the invention, the filling spout comprises an inlet orifice coupled to the casing of the pushing member and a closing member moving perpendicular to a direction of flow in the inlet orifice so as to have a shear effect of the flow when the inlet orifice is closed. Thus, in the case of a heterogeneous product, a piece of material appearing in the filling spout at the time of closure is sectioned by the closure member and very high accuracy is obtained in the weight of product introduced. in the container. Preferably, the inlet opening of the filling spout is arranged along an axis parallel to the screw of the thrust member. This minimizes the risk of physical deterioration of the texture of the product.
Selon un autre aspect avantageux de l'invention, la vis a un diamètre inférieur à un diamètre interne du carter.According to another advantageous aspect of the invention, the screw has a diameter less than an internal diameter of the casing.
Ainsi, le produit est soumis à une faible compression lors de la fermeture du bec de remplissage même lorsque la rotation de la vis n'est pas arrêtée de façon exactement simultanée.Thus, the product is subjected to a low compression when closing the filling spout even when the rotation of the screw is not stopped exactly simultaneously.
Selon encore un autre aspect avantageux de 1'inven- tion, la vis de l'organe de poussée est disposée horizontale¬ ment dans une partie cylindrique du carter qui comporte en outre une partie ayant une section décroissante entre une extrémité de la vis tournée vers le bec de remplissage et le bec de remplissage, cette partie de section décroissante comportant une génératrice inférieure horizontale dans le prolongement d'une génératrice inférieure de la partie cylindrique. Ainsi, on réduit non seulement le risque de séparation de la phase solide et de la phase liquide dans le cas d'un produit hétérogène lors d'arrêts momentanés de la machine, mais on assure en outre une vidange naturelle du 6According to yet another advantageous aspect of the invention, the screw of the thrust member is arranged horizontally in a cylindrical part of the casing which further comprises a part having a decreasing section between one end of the screw turned towards the filling spout and the filling spout, this part of decreasing section comprising a horizontal lower generator in the extension of a lower generator of the cylindrical part. This not only reduces the risk of separation of the solid phase and the liquid phase in the case of a heterogeneous product during temporary stops of the machine, but it also ensures a natural emptying of the 6

D'autres caractéristiques et avantages de l'inve tion apparaîtront à la lecture de la description qui su d'un mode de réalisation particulier non limitatif l'invention en relation avec la figure unique ci-jointe.device by gravity so that an accumulation of product in the device is avoided, in particular an accumulation of cleaning product is avoided during the washing device according to the invention. Other characteristics and advantages of the invention will appear on reading the description which follows of a particular non-limiting embodiment of the invention in relation to the attached single figure.
La figure est une représentation schématique dispositif selon l'invention partiellement en coupe selon plan vertical passant par l'axe de la vis de l'organe poussée.The figure is a schematic representation device according to the invention partially in section along a vertical plane passing through the axis of the screw of the pushed member.
En référence à la figure, le dispositif sel l'invention comporte un bec de remplissage généraleme désigné en 1 associé à un conduit d'alimentation 2 p l'intermédiaire d'un organe de poussée généralement dési en 3. Le bec de remplissage 1 est disposé à l'aplomb d' organe de pesage 4 relié à un organe de commande 5 du bec remplissage par une ligne 6 pour commander une ouverture une fermeture du bec de remplissage.Referring to the figure, the device according to the invention comprises a filling spout generally designated at 1 associated with a supply duct 2 p via a thrust member generally desired at 3. The filling spout 1 is arranged directly above the weighing member 4 connected to a control member 5 of the filling spout by a line 6 to control opening and closing of the filling spout.
L'organe de poussée comporte un carter comprena une partie cylindrique 7 disposée horizontalement et u partie de section décroissante 8 comportant une génératri inférieure 9 disposée dans le prolongement de la génératri inférieure de la partie cylindrique 7. La surface interne la partie de section décroissante à de préférence une secti circulaire de sorte que des sections successives selon plans verticaux perpendiculaires à l'axe de la vis, depu l'extrémité de la vis jusqu'au bec de remplissage, ont forme de cercles dont le point le plus inférieur coïnc avec la génératrice 9. Une vis 10 est montée pour tour dans la partie cylindrique 7 du carter et a de préférence diamètre externe d légèrement inférieur au diamètre inte D de la partie cylindrique 7 du carter. La partie de sect décroissante 8 du carter est disposée entre une extrémité la vis tournée vers le bec de remplissage 1 et le bec de remplissage 1. Le conduit d'alimentation 2 débouche à la partie supérieure du carter au voisinage d'une extrémité de la vis opposée au bec de remplissage 1. La vis 10 est entraînée en rotation par un moteur 11, par exemple un moteur électrique ou un moteur pneumatique dont la rotation est commandée par l'organe de pesage 4 par l'intermédiaire d'une ligne 12. Entre la partie cylindrique 7 du carter et le moteur 11, l'organe de poussée 3 comporte de préférence un joint annulaire double 13 délimitant une chambre annulaire 14 dans laquelle on peut faire circuler un liquide stérile ou de la vapeur pour assurer une barrière stérile entre le produit et 1'ambiance extérieure.The thrust member comprises a casing comprising a cylindrical part 7 arranged horizontally and a decreasing section part 8 comprising a lower generat 9 arranged in the extension of the lower generat of the cylindrical part 7. The internal surface the decreasing section part preferably a circular section so that successive sections along vertical planes perpendicular to the axis of the screw, from the end of the screw to the filling spout, have the shape of circles, the lowest point of which coincides with the generator 9. A screw 10 is mounted for a turn in the cylindrical part 7 of the casing and preferably has an external diameter d slightly smaller than the integer diameter D of the cylindrical part 7 of the casing. The decreasing section part 8 of the casing is arranged between one end the screw facing the filling spout 1 and the filling spout 1. The supply duct 2 opens at the upper part of the casing in the vicinity of one end of the screw opposite the filling spout 1. The screw 10 is driven in rotation by a motor 11, for example an electric motor or a pneumatic motor whose rotation is controlled by the weighing member 4 by means of a line 12. Between the cylindrical part 7 of the casing and the motor 11, the pushing member 3 preferably comprises a double annular seal 13 delimiting an annular chamber 14 in which a sterile liquid or steam can be circulated to ensure a sterile barrier between the product and the external environment.
Dans le mode de réalisation particulier illustré, le bec de remplissage 1 comporte un corps cylindrique 15 disposé verticalement dans lequel coulisse un organe de fermeture 16 également cylindrique et dont les mouvements sont commandés par l'organe de commande 5. A sa partie inférieure, le corps 15 comporte un siège 17 sur lequel l'extrémité de l'organe de fermeture 16 vient prendre appui pour une position de fermeture du bec. Le bec de remplissage 1 comporte un orifice d'entrée 18 disposé selon un axe parallèle à la vis de l'organe de poussée et accouplé à 1'extrémité de plus petit diamètre de la partie 9 de section décroissante du carter. L'organe de fermeture 16 se déplace donc perpendiculairement à une direction d'écoulement du produit dans 1*orifice d'entrée de façon à avoir un effet de cisaillement de 1'écoulement lors de la fermeture de 1'ori¬ fice d'entrée. Le fonctionnement du dispositif selon l'invention est le suivant : un récipient vide est disposé sur l'organe de pesage 4 puis le bec de remplissage 1 est ouvert et la vis 10 est simultanément mise en rotation. Le produit à condi¬ tionner est ainsi poussé en douceur vers le bec de remplis- sage 1 à travers lequel il s'écoule. On notera à ce propos que la vitesse de rotation de la vis 10 peut être variée au fur et à mesure du remplissage. En particulier lorsque le poids de produit dans le récipient atteint une valeur voisine de la consigne, on prévoit de préférence que l'organe de pesage 4 envoie au moteur d'entraînement 11 une commande de réduction de la vitesse de rotation afin d'augmenter la précision du dosage pondéral par une réduction du débit à travers le bec de remplissage juste avant sa fermeture. Lorsque le poids dans le récipient atteint la valeur de consigne, le bec de remplissage 1 est fermé et un ordre d'arrêt est simultanément envoyé au moteur d'entraînement 11.In the particular embodiment illustrated, the filling spout 1 comprises a cylindrical body 15 disposed vertically in which slides a closing member 16 also cylindrical and whose movements are controlled by the control member 5. At its lower part, the body 15 comprises a seat 17 on which the end of the closing member 16 comes to bear for a closed position of the spout. The filling spout 1 has an inlet orifice 18 arranged along an axis parallel to the screw of the thrust member and coupled to the smaller diameter end of the part 9 of decreasing section of the casing. The closing member 16 therefore moves perpendicularly to a direction of flow of the product in the inlet opening so as to have a shearing effect on the flow when the inlet opening is closed. . The operation of the device according to the invention is as follows: an empty container is placed on the weighing member 4 then the filling spout 1 is open and the screw 10 is simultaneously rotated. The product to be packaged is thus gently pushed towards the filling spout 1 through which it flows. We note in this regard that the speed of rotation of the screw 10 can be varied as and when filling. In particular when the weight of product in the container reaches a value close to the setpoint, provision is preferably made for the weighing member 4 to send the drive motor 11 a command to reduce the speed of rotation in order to increase the precise metering by weight by reducing the flow rate through the filling spout just before it closes. When the weight in the container reaches the set value, the filling spout 1 is closed and a stop order is simultaneously sent to the drive motor 11.
Lorsque le dispositif doit être nettoyé il suffit de vidanger le produit restant puis d'introduire un liquide de nettoyage par le conduit d'alimentation 2, de préférence en mettant la vis 10 en rotation afin d'éviter toute accumu¬ lation de produit entre le bord de la vis et la surface interne du carter.When the device must be cleaned, it suffices to empty the remaining product and then to introduce a cleaning liquid through the supply duct 2, preferably by rotating the screw 10 in order to avoid any accumulation of product between the edge of the screw and the inner surface of the housing.
Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des modifications sans sortir du cadre de l'invention tel que définie par les revendications.Of course, the invention is not limited to the embodiment described and modifications can be made to it without departing from the scope of the invention as defined by the claims.
En particulier, bien que l'organe de poussée 3 selon l'invention ait été représenté avec une vis horizonta¬ le, ce qui permet de réduire les risques de séparation de la phase solide et de la phase liquide dans le cas d'un produit hétérogène, on peut utiliser un dispositif comportant une vis inclinée ou même verticale. Dans ce cas la partie de carter 8 de section décroissante pourra être une partie conique disposée exactement dans 1'axe de la vis. De même, bien qu'on ait décrit l'invention avec un bec de remplissage comportant un organe de fermeture se déplaçant dans le corps du bec de remplissage selon un mouvement de coulissement alterné, on pourra également prévoir un bec de remplissage comportant un organe de fermeture rotatif ayant de préférence une arête se déplaçant perpendiculairement à l'orifice d'entrée 18 pour assurer un sectionnement d'un morceau qui se présenterait à cheval sur 1'orifice d'entrée 18 au moment de la fermeture du bec de remplissage. L'invention peut être utilisée soit à poste fixe en faisant défiler les récipients sous le bec de remplissage soit sur un carrousel où chaque récipient est chargé sur un organe de pesage et est rempli pendant la rotation du carrousel. Bien entendu dans ce cas chaque poste du carrousel est équipé d'un dispositif selon l'invention. In particular, although the thrust member 3 according to the invention has been shown with a horizonta¬ screw, which makes it possible to reduce the risks of separation of the solid phase and the liquid phase in the case of a product heterogeneous, it is possible to use a device comprising an inclined or even vertical screw. In this case, the casing part 8 of decreasing section could be a conical part arranged exactly in the axis of the screw. Likewise, although the invention has been described with a filling spout comprising a closure member moving in the body of the filling spout in an alternating sliding movement, provision may also be made for a filling spout comprising a rotary closure preferably having a moving edge perpendicular to the inlet orifice 18 to ensure a sectioning of a piece which would appear astride the inlet orifice 18 when the filling spout is closed. The invention can be used either at a fixed station by scrolling the containers under the filling spout or on a carousel where each container is loaded on a weighing member and is filled during the rotation of the carousel. Of course in this case each station of the carousel is equipped with a device according to the invention.
