Abstract

Process and implementation associated device adapted for the measurement of the inner volume of containers. This process consists in the simultaneous injection of substantially identical volumes of air or gas into the respective volumes (10A, 10B) of the bottle to be measured (9A) and of the standard bottle which is under atmospheric pressure. The determination (in 14) of the pressure difference between the two spaces, in their new state of equilibrium, allows the determination of the volume with a good accuracy. This process is implemented in a device which comprises a double equipment made of two cylinders (2A, 2B) which come into abutment on the necks (8A, 8B) of the two containers (9A, 9B). The stroke of each piston (4A, 4B) is adjusted by stops (16A, 16B) and fixes the injected volume.

Description

Procédé et dispositif pour la mesure pneumatique de volume intérieur de flacons.Method and device for pneumatic measurement of interior volume of vials.
L'invention concerne un procédé et le dispositif de mise en oeuvre associé relatifs à la mesure du volume intérieur de récipients servant au conditionnement des liquides et en particulier des flacons en verre.The invention relates to a method and the associated implementation device relating to the measurement of the internal volume of containers used for packaging liquids and in particular glass bottles.
Il existe actuellement différentes techniques pour mesurer le volume d'une capacité, en particulier celle qui consiste à emplir cette capacité d'un liquide et à mesurer la quantité ainsi utilisée. Cette technique est simple, mais lente, fastidieuse et peut difficilement répondre à l'application des nouvelles normes communautaires qui exige un contrôle plus systématique. Dans cette optique les systèmes de contrôle industriel automatiques ou semi-automatiques reposent généralement sur le principe de la comparaison du volume à mesurer avec un volume de référence. Ce principe conduit à des procédés de mesure différents : selon un procédé décrit dans le brevet français N° 1 317 298 on mesure la différence des pressions instantanées qui régnent respectivement dans les deux capacités après les avoir soumises simultanément à une même surpression, selon un second procédé on applique simultanément une faible oscillation de pression dans un cylindre de volume équivalent au récipient de référence et dans la capacité à mesurer.There are currently various techniques for measuring the volume of a capacity, in particular that which consists of filling this capacity with a liquid and measuring the quantity thus used. This technique is simple, but slow, tedious and can hardly respond to the application of new Community standards which requires more systematic monitoring. In this perspective, automatic or semi-automatic industrial control systems are generally based on the principle of comparing the volume to be measured with a reference volume. This principle leads to different measurement methods: according to a method described in French Patent No. 1,317,298, the difference in the instantaneous pressures which prevail in the two capacities is measured after having simultaneously subjected them to the same overpressure, according to a second method a small pressure oscillation is simultaneously applied in a cylinder of volume equivalent to the reference container and in the capacity to measure.
On ajuste alors la capacité du cylindre pour annuler la différence de pression entre les deux cavités. Ces méthodes de mesure présentent les inconvénients des mesures en dynamique. La méthode de mesure, selon l'invention, est simple rapide et fonctionne à sec; elle évite les inconvénients de mesures instantanées de grandeurs variables car elle procède par comparaison entre deux états d'équilibre de volume d'air au repos. Elle consiste à injecter à l'intérieur du récipient (flacon) où régnait la pression ambiante un volume d'air ou autre gaz connu et par mesure de la variation de pression interne de calculer le volume du récipient. Pour accroître la précision de la mesure, s'affranchir des dérives et éviter les corrections dues aux variations de la pression atmosphérique, on procède par comparaison avec un flacon étalon. L'injection de volumes sensiblement identiques d'air est réalisée alors simultanément dans les capacités du flacon à mesurer et du flacon étalon où règne la pression ambiante. Un capteur de pression différentiel mesure l'écart de pression entre les deux récipients dans leur nouvel état d' équilibre.The cylinder capacity is then adjusted to cancel the pressure difference between the two cavities. These measurement methods have the disadvantages of dynamic measurements. The measurement method according to the invention is simple, quick and works dry; it avoids the drawbacks of instantaneous measurements of variable magnitudes because it proceeds by comparison between two equilibrium states of air volume at rest. It consists of injecting inside the container (bottle) where the ambient pressure prevailed a volume of air or other known gas and by measuring the variation in internal pressure to calculate the volume of the container. To increase the accuracy of the measurement, to avoid drifts and avoid corrections due to variations in atmospheric pressure, we proceed by comparison with a standard bottle. The injection of substantially identical volumes of air is then carried out simultaneously in the capacities of the vial to be measured and of the standard vial where the ambient pressure prevails. A differential pressure sensor measures the pressure difference between the two containers in their new state of equilibrium.
Selon l'invention le volume injecté provient d'un cylindre dont on peut régler la cylindrée par déplacement d'une butée de réglage agissant sur la tige du piston. Ledit cylindre comporte à une extrémité un embout, qui supporte la paroi fixe de sa cavité, ledit embout est appliqué hermétiquement par l'intermédiaire d'un joint élastique sur le col du récipient; les cavités du cylindre et du flacon communiquant par un canal axial percé dans l'embout.According to the invention, the volume injected comes from a cylinder whose displacement can be adjusted by displacement of an adjustment stop acting on the piston rod. Said cylinder has at one end a nozzle, which supports the fixed wall of its cavity, said nozzle is applied hermetically by means of an elastic seal on the neck of the container; the cavities of the cylinder and of the bottle communicating by an axial channel pierced in the end piece.
Dans le cas d'une mesure par comparaison avec un flacon étalon l'équipement de mesure est double, l'injection d'air est réalisée simultanément par l'action de deux pistons mobiles dans deux cylindres identiques, adaptés sur le flacon à mesurer et sur le flacon étalon. Les deux capacités étant reliées par un conduit qui débouche avantageusement sur le canal axial de communication entre la capacité du cylindre et du flacon; un capteur de pression différentiel, installé en série sur ce conduit mesure l'écart de pression entre les deux récipients. Le mouvement simultané des deux pistons dans leur cylindre est provoqué par un vérin qui exerce un effort simultané sur les deux tiges de piston par l'intermédiaire d'un bras lié à cellesci. La course des deux pistons s'effectue entre une posi tion haute, réglée individuellement par l'action d'une vis micrométrique agissant sur chaque tige de piston et la position fin de course en butée sur le fond du cylindre. Pour l'étalonnage de ce dispositif de mesure on procède par une méthode analogue à la double pesée à tare constante; celle-ci étant constituée par un flacon de référence de volume indéterminé.In the case of a measurement by comparison with a standard bottle, the measuring equipment is double, the air injection is carried out simultaneously by the action of two movable pistons in two identical cylinders, adapted on the bottle to be measured and on the standard bottle. The two capacities being connected by a conduit which advantageously opens onto the axial channel of communication between the capacity of the cylinder and of the bottle; a differential pressure sensor, installed in series on this conduit measures the pressure difference between the two containers. The simultaneous movement of the two pistons in their cylinder is caused by a cylinder which exerts a simultaneous force on the two piston rods by means of an arm linked to these. The stroke of the two pistons takes place between a posi high position, individually adjusted by the action of a micrometric screw acting on each piston rod and the limit stop position on the bottom of the cylinder. For the calibration of this measuring device we proceed by a method analogous to double weighing at constant tare; the latter being constituted by a reference bottle of undetermined volume.
Le processus d'étalonnage se déroulant alors comme suit :The calibration process then takes place as follows:
On effectue successivement deux mesures en disposant successivement sous un même cylindre, deux flacons de volumes différents et connus, sous l'autre cylindre le même flacon de référence. Les volumes respectifs des cylindres étant réglés et constants par ailleurs.Two measurements are carried out successively by successively placing under the same cylinder, two bottles of different and known volumes, under the other cylinder the same reference bottle. The respective volumes of the cylinders being adjusted and constant elsewhere.
Les écarts de pression enregistrés lors de ces deux mesures seront notés respectivement P1 et P2. On réglera alors le gain (sensibilité) de la chaîne de mesure associée au capteur de pression différentiel de telle sorte que l'écart entre les deux séries de mesures :|Δ P1 -Δp2l , correspondant à une variation connue, soit indiqué par un effet optimum.The pressure differences recorded during these two measurements will be noted respectively P 1 and P 2 . The gain (sensitivity) of the measuring chain associated with the differential pressure sensor will then be adjusted so that the difference between the two series of measurements: | Δ P 1 -Δp 2 l, corresponding to a known variation, is indicated by an optimum effect.
On procède ensuite à un réglage du zéro correspondant à la nouvelle sensibilité du système de mesure.We then proceed to a zero adjustment corresponding to the new sensitivity of the measurement system.
Selon une disposition avantageuse du dispositif de mesure, une capacité additionnelle de volume connu peut être mise en série avec la capacité à mesurer par exemple. Cette disposition permet d'une part d'effectuer l'opération d'étalonnage avec un seul flacon de volume connu, les deux mesures nécessaires étant alors réalisées successivement sans et avec la capacité additionnelle, et d'autre part de contrôler et régler à tout moment, en cours d'épreuve, la sensibilité de la chaîne de mesure. Cette capacité additionnelle communique avantageusement avec la capacité du flacon à mesurer par un canal radial débouchant sur le canal axial de l'embout. Une vanne d'isolement installée sur ce canal radial permet de mettre en communication ces deux capacités.According to an advantageous arrangement of the measuring device, an additional capacity of known volume can be placed in series with the capacity to be measured for example. This arrangement allows on the one hand to carry out the calibration operation with a single bottle of known volume, the two necessary measurements then being carried out successively without and with the additional capacity, and on the other hand to control and adjust at any moment, during the test, the sensitivity of the measurement chain. This additional capacity advantageously communicates with the capacity of the bottle to be measured by a radial channel opening onto the axial channel of the nozzle. An isolation valve installed on this radial channel allows these two capacities to be communicated.
Cette méthode de mesure peut s'étendre, sans sortir du cadre de la présente invention, à la mesure simultanée ou en continu de plusieurs flacons à la fois; dans ce cas les cylindres relatifs à chaque flacon à tester sont avantageusement répartis à la périphérie d'un barillet dont le centre est occupé par le flacon étalon équipé de son cylindre. Le barillet peut être approvisionné d'une manière continue, les flacons étant ensuite évacués soit vers un poste de rebut, soit vers un poste de stockage selon leur degré de conformité aux normes. Il est entendu que l'intervalle de temps entre deux approvisionnements successifs est supérieur à la durée de stabilisation des pressions dans les récipients.This measurement method can extend, without departing from the scope of the present invention, to the simultaneous or continuous measurement of several bottles at the same time; in this case, the cylinders relating to each bottle to be tested are advantageously distributed around the periphery of a barrel, the center of which is occupied by the standard bottle equipped with its cylinder. The barrel can be supplied continuously, the bottles then being evacuated either to a waste station or to a storage station according to their degree of compliance with standards. It is understood that the time interval between two successive supplies is greater than the duration of stabilization of the pressures in the containers.
Le dessin annexé illustre, à titre d'exemple, un mode de réalisation du dispositif conforme à la présente invention.The appended drawing illustrates, by way of example, an embodiment of the device according to the present invention.
Tel qu'il est représenté, le dispositif présente une s;ymétrie dans laquelle le vérin de manoeuvre 1 occupe une position centrale.As shown, the device has a symmetry in which the actuating cylinder 1 occupies a central position.
Il est constitué de deux cylindres 2A et 2B dont les volumes utiles 3A et 3B sont limités d'une part par un piston 4A et 4B et par la face supérieure 5A et 5B d'un embout 6A soudé ou vissé à l'extrémité du cylindre 2A.It consists of two cylinders 2A and 2B whose useful volumes 3A and 3B are limited on the one hand by a piston 4A and 4B and by the upper face 5A and 5B of a nozzle 6A welded or screwed to the end of the cylinder 2A.
Dans la suite de la description on adoptera la notation suivante :In the following description, the following notation will be adopted:
Les éléments symétriques du dispositif seront repérés par un même chiffre affecté de l'indice A pour les éléments de gauche et de l'indice B pour les éléments de droite. On se limitera par la suite à l'indication des repères des éléments de gauche.The symmetrical elements of the device will be identified by the same number assigned with the index A for the elements on the left and the index B for the elements on the right. We will limit ourselves thereafter to the indication of the marks of the elements on the left.
Chaque embout 6A est appliqué par l'intermédiaire d'un joint élastique 7A sur le col supérieur 8A du flacon testé 9A et du flacon étalon 9B. Les capacités 3A des cylindres communiquent respectivement avec les capacités 10A du flacon testé 9A et du flacon de référence 9B, par un canal axial 11A percé dans chaque embout 6A. Un canal avantageusement radial 12A percé dans chaque embout 6A communique à une extrémité avec le canal axial 11A et débouche à l'autre extrémité, à l'ambiance, par l'intermédiaire d'un bossage 13A. Un capteur de pression absolue pourra être monté dans le cas d'une mesure en absolu sur le bossage 13A de l'embout 6A installé sur le flacon à tester 9A. Dans le cas le plus général d'une mesure de volume par comparaison avec un volume de référence, un capteur de pression différentiel 14 sera monté en série sur un conduit 15 monté entre les bossages 13A. Le déplacement des pistons 4A s'effectue entre une position haute réglée par l'action d'une vis micrométrique 16A agissant avantageusement, mais pas nécessairement, sur l'extrémité libre de la tige de commande 17A du piston 4A, et une position basse de butée contre le fond 5A.Each nozzle 6A is applied via an elastic seal 7A to the upper neck 8A of the tested bottle 9A and the standard bottle 9B. The capacities 3A of the cylinders communicate respectively with the capacities 10A of the tested bottle 9A and of the reference bottle 9B, by an axial channel 11A pierced in each end piece 6A. An advantageously radial channel 12A pierced in each endpiece 6A communicates at one end with the axial channel 11A and opens at the other end, into the atmosphere, via a boss 13A. An absolute pressure sensor can be mounted in the case of an absolute measurement on the boss 13A of the nozzle 6A installed on the bottle to be tested 9A. In the most general case of a volume measurement by comparison with a reference volume, a differential pressure sensor 14 will be mounted in series on a conduit 15 mounted between the bosses 13A. The displacement of the pistons 4A takes place between a high position adjusted by the action of a micrometric screw 16A acting advantageously, but not necessarily, on the free end of the control rod 17A of the piston 4A, and a low position of stop against the bottom 5A.
Les vis micrométriques 16A seront avantageusement supportées par un portique 31 installé au-dessus du dispositif de mesure.The micrometric screws 16A will advantageously be supported by a gantry 31 installed above the measuring device.
Le déplacement des pistons 4A est assuré par le vérin de manoeuvre 1 qui exerce avantageusement un effort simultané, sur les deux tiges 17A, par l'intermediaire d'un bras 18 fixé rigidement ou articulé sur le piston 19 du vérin 1.The displacement of the pistons 4A is ensured by the actuating cylinder 1 which advantageously exerts a simultaneous force, on the two rods 17A, by means of an arm 18 rigidly fixed or articulated on the piston 19 of the cylinder 1.
La liaison entre ledit bras 18 et les tiges 17A est avantageusement élastique; elle est constituée d'un système de deux ressorts 20A-21A disposés en série, de part et d'autre d'une pièce de raccordement 22A, solidaire de la tige 17A et maintenue par l'action desdits ressorts 20A-21A entre les parois 23A d'un évi dément 26A pratiqué à chaque extrémité dudit bras 18. Les ressorts conjugués 20A-21A et 20B-21B sont fixés, par une de leurs extrémités, sur la pièce de raccordement 22A à l'autre extrémité sur les flasques opposés 23A de l'étrier 26A.The connection between said arm 18 and the rods 17A is advantageously elastic; it consists of a system of two springs 20A-21A arranged in series, on either side of a connecting piece 22A, integral with the rod 17A and held by the action of said springs 20A-21A between the walls 23A of an evi demented 26A practiced at each end of said arm 18. The conjugate springs 20A-21A and 20B-21B are fixed, by one of their ends, on the connecting piece 22A at the other end on the opposite flanges 23A of the bracket 26A .
Une capacité additionnelle 27 de volume connu pourra être mise avantageusement en série avec la capacité 10A du volume à mesurer. Elle pourra être avantageusement adaptée directement sur l'embout 6A par l'intermédiaire d'un raccord fileté 28. Cette capacité additionnelle 27 communique avec la capacité à tester 10A par un canal avantageusement radial 29 percé dans l'embout 6A et débouchant dans le canal axial 11A. Une vanne d'isolement 30 sera placée sur le circuit de communication entre la capacité additionnelle et la capacité à tester 10A; elle pourra être avantageusement intégrée dans le corps de l'embout 6A. An additional capacity 27 of known volume could advantageously be placed in series with the capacity 10A of the volume to be measured. It can advantageously be adapted directly to the end piece 6A by means of a threaded connection 28. This additional capacity 27 communicates with the capacity to be tested 10A by an advantageously radial channel 29 pierced in the end piece 6A and opening into the channel axial 11A. An isolation valve 30 will be placed on the communication circuit between the additional capacity and the capacity to be tested 10A; it can advantageously be integrated into the body of the end piece 6A.
