Description

La présente invention concerne les installations de remplissage dé récipient, et plus particulièrement, un procédé et un dispositif de dosage de matériau de remplissage de récipients dans une machine de remplissage à dosage pondéral.The present invention relates to container filling installations, and more particularly, to a method and a device for dosing container filling material in a filling machine with metering by weight.

Le dosage pondéral s'impose de plus en plus dans les installations de remplissage en matériaux liquides ou divisés, par exemple dans les industries alimentaires ou pharmaceutiques, en raison de l'obtention de résultats plus précis et plus fiables par rapport aux installations à dosage volumétrique. Cette technique nécessite l'aménagement, pour chaque tête de remplissage, d'une balance de pesage associée à des moyens de détection pour commander la tête de remplissage en fonction du poids de matériau de remplissage effectivement délivré. Jusqu'à présent, en raison des conditions sévères d'utilisation de tels matériels, on prévoyait, associé à un élément mobile de la balance, un moyen de détection du type à détection de proximité, comme décrit dans le brevet français n° 2.098.780 au nom de l'inventeur. Cette technique à commande par tout ou rien donne toute satisfaction en ce qui concerne la robustesse de la fiabilité d'utilisation mais présente l'inconvénient de devoir tenir compte et corriger par ailleurs des paramètres fluctuants des installations de remplissage, tels que par exemple ceux relevant du tarage des récipients vides ou du poids de la colonne de matériau délivré entre la sortie de la tête de remplissage et le récipient, imposant le recours à des moyens de correction des détecteurs de proximité comme décrit par exemple dans la demande de brevet français n° 78/1787 au nom de la demanderesse.Weight dosing is becoming more and more necessary in filling installations with liquid or divided materials, for example in the food or pharmaceutical industries, because of obtaining more precise and more reliable results compared to installations with volumetric dosing . This technique requires the arrangement, for each filling head, of a weighing scale associated with detection means for controlling the filling head as a function of the weight of filling material actually delivered. Until now, due to the severe conditions of use of such equipment, provision has been made, associated with a mobile element of the balance, for detection means of the proximity detection type, as described in French patent No. 2,098. 780 in the name of the inventor. This all-or-nothing control technique gives all satisfaction with regard to the robustness of the reliability of use but has the disadvantage of having to take into account and also correct fluctuating parameters of the filling installations, such as for example those relating to the taring of empty containers or the weight of the column of material delivered between the outlet of the filling head and the container, requiring the use of means for correcting proximity switches as described for example in French patent application No. 78/1787 in the name of the applicant.

La présente invention a précisément pour objet de proposer un procédé et un dispositif de dosage de matériau de remplissage de récipients dans des machines de remplissage à dosage pondéral, obviant aux inconvénients ci-dessus, offrant, tout en conservant une grande fiabilité en utilisation, une grande souplesse d'utilisation en intégrant des composants logiques programmables et permettant de moduler les conditions de fonctionnement de l'installation, soit en injectant des données image de paramètre spécifiques, soit automatiquement en cours de fonctionnementThe object of the present invention is precisely to propose a method and a device for dosing container filling material in filling machines with weight dosing, overcoming the above drawbacks, offering, while retaining high reliability in use, a great flexibility of use by integrating programmable logic components and making it possible to modulate the operating conditions of the installation, either by injecting image data of specific parameters, or automatically during operation

Pour ce faire, le-procédé selon la présente invention, mis en oeuvre dans une machine de remplissage comprenant au moins un poste de remplissage/pesage avec une tête de remplissage, une balance de pesage à équipage en parallè- logramme, des moyens de détection étant associés au disposi- tif de pesage pour commander la tête de remplissage, consiste à coupler mécaniquement à un élément mobile de l'équipage de la balance un capteur de force et à transmettre de façon continue le signal de sortie du capteur à une unité logique-programmable à mémoire fournissant un signal de commande à la tête de remplissage lorsque la valeur de poids détectée atteint une valeur déduite et corrigée de la valeur nominale en-' registrée.To do this, the process according to the present invention, implemented in a filling machine comprising at least one filling / weighing station with a filling head, a weighing balance with parallelogram equipment, detection means being associated with the provi- t if weighing for controlling the filling head, is mechanically coupled to a movable member of the crew of the balance a force sensor and to transmit continuously the output signal of the sensor unit logic-programmable with memory providing a control signal to the filling head when the detected weight value reaches a value deducted and corrected from the recorded nominal value.

Selon une autre caractéristique de la présente invention, le dispositif de dosage pour une telle machine de remplissage, plus particulièrement mais non exclusivement du type à carrousel multipostes, comprenant au moins un poste de remplissage avec une tête de remplissage commandable et une balance de pesage à équipage en parallélogramme, des moyens de détection étant associés à la balance de pesage pour fournir un signal de commande à la tête de remplissage, comprend un capteur de force couplé mécaniquement à un élément mobile d'équipage de la balance et relié à une-première entrée d'une unité logique programmable à mémoire comprenant une seconde entrée de commande et de mise en mémoire,et dont la sortie est reliée à la tête de remplissage.According to another characteristic of the present invention, the metering device for such a filling machine, more particularly but not exclusively of the multi-station carousel type, comprising at least one filling station with a controllable filling head and a weighing scale with parallelogram equipment, detection means being associated with the weighing balance to supply a control signal to the filling head, comprises a force sensor mechanically coupled to a mobile element of the equipment of the balance and connected to a first entry of a programmable logic unit with memory comprising a second control and storage input, the output of which is connected to the filling head.

Outre les problèmes de conditions sévères d'utilisation,pour ce qui est de la température et de l'humidité,les machines de remplissage,notamment du type à carrousel,se sont révélées jusqu'à présent rebelles à l'intégration de composants électroniques en raison notamment des hauts niveaux de vibration dans de larges gammes de fréquence rencontrés dans de telles machines.La demanderesse,forte de son expérience de plusieurs années dans le domaine du dosage pondéral,et à la suite de nombreuses expériences,s'est rendue compte que l'utilisation d'un transducteur de force,par exemple du type à jauge de contrainte,ne pouvait se faire qu'en association avec une balance de pesage à équipage en parallélogramme,dont la robustesse et sa capacité à "encaisser" les couples parasites inéluctablement induits sur le plateau de mesure dans les installations-a gran­ de cadence autorisaient néanmoins,grâce à la faible inertie de ces balances,équipées de roulements d'articulation,des capacités de mesure extrêmement fines.En effet,notamment dans les carrousels de remplissage,outre les problèmes inertiels tenant au caractère rotatif de l'installation,les récipients,par exemple les bouteilles,pour être correctement positionnés au-dessous des têtes de remplissage sont mis en place dynamiquement lors de leur chargement sur le carrousel de remplissage par des brides de centrage,telles que celles représentées sur la figure 1 et transmettent alors des couples parasites importants et variables à l'équipage de pesée qui rendent illusoire en raison,en outre,des variations importantes de localisation du centre de gravité du récipient,un accouplement mécanique direct entre le plateau de réception/pesage et un transducteur de force.In addition to the problems of severe conditions of use, with regard to temperature and humidity, filling machines, in particular of the carousel type, have hitherto proved rebellious to the integration of electronic components in This is due in particular to the high levels of vibration in wide frequency ranges encountered in such machines. The Applicant, drawing on its experience of several years in the field of weight dosing, and following numerous experiments, has realized that the use of a force transducer, for example of the strain gauge type, could only be done in combination with a weighing scale with parallelogram equipment, whose robustness and its ability to "absorb" parasitic torques inevitably induced on the measurement plate in installations-at a high rate nevertheless allowed, thanks to the low inertia of these scales, equipped with articulation bearings, ext measurement capacities In fact, especially in the filling carousels, in addition to the inertial problems due to the rotary nature of the installation, the containers, for example the bottles, to be correctly positioned below the filling heads are dynamically placed when they are loaded onto the filling carousel by centering flanges, such as those shown in FIG. 1 and then transmit significant and variable parasitic torques to the weighing crew which make it illusory due, moreover, to significant variations locating center of gravity of the container, direct mechanical coupling between the receiving / weighing platform and a force transducer.

Selon une autre caractéristique de la présente invention, le capteur de force étant du type à lame sensible et à jauge de contrainte, le couplage mécanique entre le capteur et l'élément mobile ou fléau de l'équipage de la balance est réalisé par un câble de traction.According to another characteristic of the present invention, the force sensor being of the sensitive blade and strain gauge type, the mechanical coupling between the sensor and the moving element or beam of the balance equipment is carried out by a cable traction.

En effet, en raison des taux de vibration susmentionnés, la demanderesse a constaté que le signal de sortie d'un transducteur fonctionnant en compression était quasiment inutilisable dans une machine de remplissage, alors que la sollicitation en traction, plus particulièrement par un câble souple, permet de diminuer avec un facteur de 10 les effets des vibrations sur la lame sensible du capteur.Indeed, due to the aforementioned vibration rates born, the Applicant has found that the output signal from a transducer operating in compression was almost unusable in a filling machine, while the tensile stress, more particularly by a flexible cable, makes it possible to decrease with a factor of 10 the effects of vibrations on the sensitive sensor plate.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description suivante d'un mode de réalisation donné à titre illustratif mais nullement limitatif, faite en relation avec les dessins annexés, sur lesquels :

  • La figure 1 est une vue schématique en coupe d'un poste de pesage d'un carrousel de remplissage à dosage pondéral équipé du dispositif selon la présente invention; et
  • La figure 2 est une vue en plan.d'une telle installation de remplissage permettant d'apprécier les séquences du procédé de contrôle de dosage avec le dispositif de la figure 1.
Other characteristics and advantages of the present invention will emerge from the following description of an embodiment given by way of illustration but in no way limiting, made in relation to the appended drawings, in which:
  • Figure 1 is a schematic sectional view of a weighing station of a weight metering filling carousel equipped with the device according to the present invention; and
  • FIG. 2 is a plan view of such a filling installation making it possible to assess the sequences of the dosage control method with the device of FIG. 1.

Sur la figure 2, on reconnaît un carrousel de remplissage multipostes 1 alimenté en récipients à remplir par un carrousel de transfert amont 2 prélevant les récipients 3 sur un convoyeur linéaire 4,les récipients remplis dans le carrousel de remplissage 1 étant soustraits à ce dernier et remis en circulation sur le convoyeur linéaire 4 par un carrousel de transfert de sortie 5. Le carrousel de remplissage 1 est pourvu d'un certain nombre-de postes de pesage (typiquement 12 ou 24) du type représenté sur la figure 1.In FIG. 2, there is a multi-station filling carousel 1 supplied with containers to be filled by an upstream transfer carousel 2 picking up the containers 3 on a linear conveyor 4, the containers filled in the filling carousel 1 being withdrawn therefrom and recirculated on the linear conveyor 4 by an output transfer carousel 5. The filling carousel 1 is provided with a number of weighing stations (typically 12 or 24) of the type shown in FIG. 1.

Sur cette figure 1, on reconnaît la tête de remplissage 6, par exemple du type à commande de clapet électromagnétique, disposée à l'aplomb d'un plateau récepteur 7 d'une balance de pesage du type à équipage à parallélogramme, généralement référencée 8. La balance 8 se compose d'une colonne porteuse 9, montée sur un bâti 10 solidaire de l'arbre creux 11 du carrousel, d'une colonne flottante 11, et d'un fléau inférieur 12,.le parallélogramme étant complété par une traverse supérieure 13, ces différents éléments étant articulés les uns par rapport aux autres au moyen de roulement à bille tel que celui figuré en 14. Selon la présente invention, la balance 8 a une configuration particulièrement compacte, avec la hauteur moyenne des colonnes supérieure ou double de la longueur des traverses. Le plateau 7 est relié à la colonne flottante 11 par un montant tubulaire creux 15.In this FIG. 1, we can recognize the filling head 6, for example of the type with electromagnetic valve control, placed directly above a receiving plate 7 of a weighing balance of the type with parallelogram equipment, generally referenced 8 The balance 8 consists of a supporting column 9, mounted on a frame 10 secured to the hollow shaft 11 of the carousel, a floating column 11, and a lower beam 12, the parallelogram being completed by a upper cross member 13, these various elements being articulated with respect to each other by means of ball bearings such than that shown in 14. According to the present invention, the balance 8 has a particularly compact configuration, with the average height of the columns greater than or double the length of the crosspieces. The plate 7 is connected to the floating column 11 by a hollow tubular upright 15.

Conformément à un aspect de la présente invention, pour ajuster la mise à niveau du plateau de balance 7 avec le plateau 16 du carrousel, le montant 15 a son extrémité infé- 'rieure portant sur une came à surface évolutive 17 commandable par un arbre 18, le montant 15 étant fixé sur la colonne flottante 11, une fois mis à niveau, par des plaques de bridage 19. Les différentes balances du carrousel 1 sont traditionnellement logées dans un carter comprenant un capot supérieur 20 et une jupe périphérique externe 21. Pour éviter les projections des matériaux de remplissage à l'intérieur du carter, au montant 15 du plateau 7 est associé un système de labyrinthe à cylindres 22, comme représenté sur la figure'l. Le plateau 7 est traditionnellement équipé de brides ouvertes 23 de centrage des récipients, situées, pour les bouteilles au niveau du col de-ces bouteilles et induisant les problèmes de couplés parasites susmentionnés. L'équipage de balance 8 peut être complété par un contrepoids 24, monté sur une extension du fléau 12, quoique ce contrepoids induise des problèmes de couples inertiels nécessitant une compensation massique de l'autre côté de la balance, un tel contrepoids n'étant pas nécessaire avec le.capteur de force selon 1a présente invention.According to one aspect of the present invention, for adjusting the leveling of the scale plate 7 with the plate 16 of the carousel, the post 15 has its lower end 'higher on a cam surface 17 scalable controllable by a shaft 18 , the upright 15 being fixed to the floating column 11, once leveled, by clamping plates 19. The various scales of the carousel 1 are traditionally housed in a casing comprising an upper cover 20 and an external peripheral skirt 21. For avoid projections of the filling materials inside the casing, the upright 15 of the plate 7 is associated with a cylinder labyrinth system 22, as shown in FIG. The plate 7 is traditionally equipped with open flanges 23 for centering the containers, located for the bottles at the neck of these bottles and inducing the problems of parasitic couplings mentioned above. The balance equipment 8 can be completed by a counterweight 24, mounted on an extension of the beam 12, although this counterweight induces inertial torque problems requiring mass compensation on the other side of the balance, such a counterweight being not necessary with the force sensor according to the present invention.

Le transducteur de force 25, comportant une lame sensible 26 à jauge de contrainte, est monté sur un étrier 27, sensiblement dans le prolongement de la traverse supérieure 13, l'étrier 27 étant fixé par les extrémités intérieures de ses branches latérales à la colonne support 9. Conformément à la présente invention, cette colonne support 9 est en outre fixée au bâti 10 avec interposition d'éléments élastiques en élastomère 28, par exemple du type dit "Silent-Block". La lame sensible 26 du capteur 25 est couplée mécaniquement à l'extrémité extérieure du fléau 12 par un câble 28 exerçant normalement une traction sur la lame sensible dans une direction perpendiculaire au plan de celle-ci. Conformément à un aspect de la présente invention, le câble 28 traverse l'orifice de la lame sensible 26 et un ressort hélicoïdal 29, à l'extrémité supérieure duquel est reliée l'extrémité adjacente du câble 28,le ressort 29 portant par une coupelle profilée sur la lame 26. Le ressort 29 est du type à grande raideur et conçu pour commencer à s'écraser sous l'application d'une force de compression de l'ordre de 20 kg, c'est-à-dire largement supérieure au poids normal des récipients remplis à peser par la balance. Pour des poids de récipients à mesurer de l'ordre de 2 à 5 kg, le capteur 25 est choisi avec une lame sensible de la classe des 20 kg. Pour éviter tout endommagement accidentel de la lame sensible, lé débattement angulaire vers le bas du fléau 12 est limité par une butée réglable 30.The force transducer 25, comprising a sensitive blade 26 with strain gauge, is mounted on a stirrup 27, substantially in the extension of the upper cross member 13, the stirrup 27 being fixed by the inner ends of its lateral branches to the column support 9. According to the present invention, this support column 9 is also fixed to the frame 10 with the interposition of elastic elastomer elements 28, for example of the so-called "Silent-Block" type. The sensitive blade 26 of the sensor 25 is mechanically coupled to the outer end of the beam 12 by a cable 28 carrying normally a traction on the sensitive blade in a direction perpendicular to the plane thereof. According to one aspect of the present invention, the cable 28 passes through the orifice of the sensitive blade 26 and a helical spring 29, at the upper end of which is connected the adjacent end of the cable 28, the spring 29 carrying by a cup profiled on the blade 26. The spring 29 is of the high stiffness type and designed to start to crush under the application of a compressive force of the order of 20 kg, that is to say much greater at the normal weight of the filled containers to be weighed by the balance. For container weights to be measured of the order of 2 to 5 kg, the sensor 25 is chosen with a sensitive blade of the 20 kg class. To avoid any accidental damage to the sensitive blade, the downward angular movement of the beam 12 is limited by an adjustable stop 30.

Conformément à la présente invention, la sortie du capteur de force 25 est acheminée par une ligne 31 à une entrée de mesure 32 d'une unité logique programmable à microprocesseur 33, logée dans un support avec amortisseur au-dessous de l'équipage,de balance 8. L'unité 'logique à mémoire 33 comprend au moins une seconde entrée 34 , permettant l'injection en mémoire de données déterminées et l'inscription de pas de programme déterminés. Une sortie de calcul 35 de l'unité logique 33 est reliée par une-ligne 36, à la tête de remplissage 6, pour en commander sélectivement l'ouverture et la fermeture en fonction de conditions élaborées par l'unité logique 33,typiquement lorsque la valeur de poids mesurée par le capteur,convertiè en numérique, atteint une valeur interne affichée.According to the present invention, the output of the force sensor 25 is routed by a line 31 to a measurement input 32 of a programmable logic unit with microprocessor 33, housed in a support with damper below the crew, 8. the balance unit logical memory 33 comprises at least one second inlet 34, for injecting data memory determined and the inclusion of no determined program. A calculation output 35 of the logic unit 33 is connected by a line 36, to the filling head 6, to selectively control the opening and closing thereof according to conditions developed by the logic unit 33, typically when the weight value measured by the sensor, converted to digital, reaches an internal displayed value.

Le procédé de contrôle de dosage selon la présente invention sera maintenant explicité plus en détail en référence avec le schéma d'implantation de la figure 2. Au début d'un cycle de remplissage, les données propres à ce cycle, notamment les valeurs de poids désirées selon le type de produits à remplir et les dimensions des récipients,sont injectées par l'entrée 34 dans les unités logiques 33 des balances des différents postes de remplissage du carrousel 1. Supposons par exemple que le poids désiré du matériau de remplissage du récipient soit de 1000 grammes. Avec le procédé de l'invention, on ne se préoccupe pas d'effectuer au préalable une détermination moyenne des tares des récipients à remplir non plus que de la valeur moyenne de la colonne de liquide ou de produit divisé évoqué dans la partie introductive de la description.On affecte simplement dans les unités logiques 33 une valeur désirée initiale inférieure au poids requis, par exemple 900 grammes. Un premier passage de récipients fournis par le convoyeur linéaire 4, permet, pour les postes de remplissage successifs, aux capteurs associés 25 de transmettre aux unités logiques 33 correspondantes, lors de la première phase de transfert angulaire A-B depuis la zone de chargement A, (angle A-B de l'ordre de 15 à 20°)-, des signaux de mesure leur faisant prendre en compte le poids de la tare constituée par chaque récipient, ce qui permet de ré-' caler les registres de l'unité logique 33 pour lui faire effectuer une mesure continue en poids net lors de la phase de transfert angulaire B-C en amont de la zone de déchargement D, c'est-à-dire avant que des éléments structurels du carrousel de transfert 5 ne commencent à venir en contact avec les récipients. L'angle C-D est choisi de l'ordre de 10 à 15°. En fonction du calibrage volontairement minoré de ce cycle de démarrage, l'unité logique 33 aura fourni, par sa sortie 35, un signal de fermeture de la tête 6 lorsque la valeur détectée par le capteur 25 - décalée de la prise en compte initiale du tarage - aura atteint 900 grammes, et ce, en amont de la zone angulaire C. Une fois la commande de la tête 6 effectuée, l'unité logique 33 enregistre le poids réel du récipient rempli, et, pendant la phase de transfert angulaire à vide D-A, effectue la comparaison avec la valeur désirée enregistrée pour la corriger en tenant compte ainsi des paramètres propres au cycle de remplissage considéré, tels que le poids de colonne de matériau ou la force d'impact de celui- ci selon le débit de remplissage, de sorte que la valeur prise en compte dans le cycle suivant pour commander la tête de fermeture sera différente de la valeur exacte désirée et de la valeur initialement affichée pour fournir, dès ce second cycle, le décalage du tarage s'effectuant à chaque fois lors du transfert A-B, le poids exact requis; en l'occurrence 1000 grammes à ± 5 grammes.The dosage control method according to the present invention will now be explained in more detail with reference to the layout diagram in FIG. 2. At the start of a filling cycle, the data specific to this cycle, in particular the weight values desired according to the type of products to be filled and the dimensions of the containers, are injected through the inlet 34 into the logic units 33 of the balans these different filling stations of the carousel 1. Suppose for example that the desired weight of the filling material of the container is 1000 grams. With the method of the invention, it is not concerned to carry out beforehand an average determination of the tares of the containers to be filled, no more than the average value of the column of liquid or of divided product mentioned in the introductory part of the We simply assign in logical units 33 an initial desired value lower than the required weight, for example 900 grams. A first passage of containers supplied by the linear conveyor 4, allows, for successive filling stations, the associated sensors 25 to transmit to the corresponding logic units 33, during the first angular transfer phase AB from the loading area A, ( angle AB of the order of 15 to 20 °) -, measurement signals making them take into account the weight of the tare formed by each container, which makes it possible to reset the registers of the logic unit 33 for make it carry out a continuous measurement in net weight during the angular transfer phase BC upstream of the unloading zone D , that is to say before structural elements of the transfer carousel 5 begin to come into contact with the containers. The angle CD is chosen in the range of 10 to 15 °. Depending on the voluntarily reduced calibration of this start-up cycle, the logic unit 33 will have supplied, by its output 35, a signal for closing the head 6 when the value detected by the sensor 25 - shifted from the initial taking into account of the taring - will have reached 900 grams, upstream of the angular zone C. Once the head 6 has been controlled, the logic unit 33 records the actual weight of the container filled, and, during the angular transfer phase at vacuum DA, performs the comparison with the desired value recorded to correct it, thus taking into account the parameters specific to the filling cycle considered, such as the weight of the material column or the impact force thereof depending on the filling rate , so that the value taken into account in the following cycle to order the head of closing will be different from the exact value desired and from the value initially displayed to provide, from this second cycle, the taring offset being effected each time during the AB transfer, the exact weight required; in this case 1000 grams to ± 5 grams.

Le procédé selon la présente invention permet en outre de tenir compte de quantités non désirées de matériau sur les plateaux 7, provenant par exemple de fuites de récipients précédents et d'actionner, par une sortie 37, un dispositif d'alarme et/ou d'affichage, signalant le mauvais fonctionnement d'une tête tel que détecté lors de la phase de comparaison dans la phase de transfert angulaire D-A.The method according to the present invention also makes it possible to take into account unwanted quantities of material on the plates 7, originating for example from leaks from previous containers and to actuate, by an outlet 37, an alarm device and / or a display, signaling the malfunction of a head as detected during the comparison phase in the angular transfer phase DA.

Quoique la présente invention ait été décrite-en relation avec des modes de réalisation particuliers,-elle ne s'en trouve pas limitée mais est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art.Although the present invention has been described - in relation to particular embodiments, - it is not limited thereto, but is on the contrary liable to modifications and variants which will appear to those skilled in the art.
