Description

Machine de remplissage d'outrés ou analogues comportant un dispositif de commande à cames Filling machine for wineskins or the like comprising a cam control device
La présente invention concerne le domaine du conditionnement et de la distribution de liquides, en particulier de liquides alimentaires, dans des petits récipients souples, ces récipients étant munis, à cet effet, de robinets, d'obturateurs tels que bouchons ou tous autres accessoires de distribution ou de soutirage, et a pour objet une machine de remplissage d'outrés ou analogues comportant un dispositif de commande à cames.The present invention relates to the field of packaging and distribution of liquids, in particular food liquids, in small flexible containers, these containers being provided, for this purpose, with taps, shutters such as plugs or any other accessories of dispensing or racking, and relates to a filling machine for wineskins or the like comprising a cam control device.
Actuellement, le conditionnement et la distribution de certaines boissons alimentaires, notamment de vins de table, de jus de fruits ou de lait stérilisé ultra-haute température, s'effectuent au moyen de récipients souples, tels que des outres en matière synthétique, communément connues sous le nom de "bag in box", généralement munies de robinets ou de bouchons fixés sur la bonde de vidange de ces récipients.Currently, the packaging and distribution of certain food drinks, in particular table wines, fruit juices or ultra-high temperature sterilized milk, are carried out by means of flexible containers, such as plastic bottles, commonly known. under the name of "bag in box", generally provided with taps or plugs fixed on the drain of these receptacles.
Ces outres sont réalisées à partir de films multicouche comportant généralement une couche barrière agencée entre des couches étanches et de protection interne et externe, puis conditionnées à vide dans des cartons de regroupement et acheminées vers leur destination de remplissage. Ce mode de réalisation permet une fabrication rapide des outres, ainsi qu'une bonne maîtrise de qualité.These bottles are produced from multilayer films generally comprising a barrier layer arranged between waterproof layers and internal and external protection, then vacuum packed in grouping boxes and sent to their filling destination. This embodiment allows rapid manufacturing of bottles, as well as good quality control.
Les évolutions commerciales récentes tendent à la limitation du nombre des étapes inteπnédiaires entre la production du liquide et sa commercialisation, dans le but de réduire les frais annexes de main d'œuvre, de transport de conditionnements vides encombrants et de stockage. A cet effet, il a été proposé de réaliser simultanément la fabrication et le remplissage des outres en un site de production unique, les outres remplies étant ensuite acheminées vers les lieux de vente et/ou de consommation. Une telle organisation du conditionnement et de la distribution nécessite la mise en œuvre d'installations spécifiques, dans lesquelles la fabrication et le remplissage des outres sont réalisés simultanément.Recent commercial developments tend to limit the number of intermediate steps between the production of the liquid and its marketing, in order to reduce the associated costs of labor, transport of bulky empty packaging and storage. To this end, it has been proposed to simultaneously manufacture and fill the bottles in a single production site, the filled bottles being then sent to the places of sale and / or consumption. Such an organization of packaging and distribution requires the implementation of specific installations, in which the manufacturing and filling of the wineskins are carried out simultaneously.
Ces installations connues permettent donc, a priori, de satisfaire aux nouvelles exigences en matière de conditionnement de produits liquides. Cependant, dans ces installations connues, la machine de remplissage est soumise à des sollicitations très importantes préjudiciables à un fonctionnement fiable à haut régime. En effet, les machines de remplissage équipant ces installations sont généralement des machines à postes multiples de remplissage individuel des outres, dont chaque poste comporte un ensemble de moyens permettant la prise et l'immobilisation de l'outre, la manipulation de l'obturateur en vue de permettre le remplissage de ladite outre, puis le remplissage de celle-ci, la fermeture de l'outre et son évacuation en vue du conditionnement. Les différentes opérations réalisées par ces machines de remplissage sont toutes commandées et contrôlées par l'intermédiaire d'un dispositif de commande à vérins pneumatiques et de contrôle à détecteurs de position et/ou de fin de course électriques ou électro-optiques.These known installations therefore make it possible, a priori, to meet the new requirements in terms of packaging of liquid products. However, in these known installations, the filling machine is subjected to very high stresses detrimental to reliable operation at high speed. Indeed, the filling machines equipping these installations are generally multiple-station machines for individual filling of the bottles, each station comprising a set of means allowing the gripping and immobilization of the addition, the handling of the shutter in view to allow the filling of said addition, then the filling thereof, the closure of the addition and its evacuation for packaging. The various operations carried out by these filling machines are all commanded and controlled by means of a control device with pneumatic cylinders and control with electric or electro-optical position and / or limit switch detectors.
Il en résulte que le dispositif de commande et de contrôle est particulièrement complexe et que son installation et sa maintenance sont relativement coûteux. En effet, du fait que ces machines réalisent un grand nombre d'opérations unitaires par heure, les vérins les équipant sont soumis à un mode de fonctionnement très exigeant, de sorte que leur remplacement suite à la fatigue doit être envisagé à des délais relativement courts, ce qui entraîne, d'une part, des arrêts machines correspondants et, d'autre part, des surcoûts de production.As a result, the command and control device is particularly complex and its installation and maintenance are relatively expensive. In fact, because these machines carry out a large number of unit operations per hour, the jacks fitted to them are subjected to a very demanding operating mode, so that their replacement following fatigue must be envisaged at relatively short deadlines. , which leads, on the one hand, to corresponding machine downtime and, on the other hand, additional production costs.
En outre, le fonctionnement des machines actuelles entraîne une importante consommation d'énergie, en particulier du fait de la transformation d'énergie électrique nécessaire à la production d'énergie pneumatique, qui n'est pas recyclable, ainsi que pour l'annulation de l'effet des frottements et des inerties des masses de la machine pendant les phases successives d'accélération négative et positive. II convient aussi de remarquer que ces machines doivent présenter un fonctionnement de type asynchrone, qui entraîne forcément des durées de cycle relativement longues et donc un rendement relativement faible.In addition, the operation of current machines results in significant energy consumption, in particular due to the transformation of electrical energy necessary for the production of pneumatic energy, which is not recyclable, as well as for the cancellation of the effect of friction and inertia of the machine masses during the successive phases of negative and positive acceleration. It should also be noted that these machines must have an asynchronous type of operation, which necessarily results in relatively long cycle times and therefore relatively low efficiency.
La présente invention a pour but de pallier les inconvénients des machines de remplissage d'outrés connues à ce jour en proposant une machine de remplissage de ce type comportant un dispositif de commande à cames permettant une simplification de la construction, une meilleure fiabilité de fonctionnement et une maintenance simplifiée entraînant des coûts de fabrication de la machine et de production d'outrés remplies moins élevés.The object of the present invention is to overcome the drawbacks of the filling machines for bottles furthermore known to date by proposing a filling machine of this type comprising a cam control device allowing a simplification of the construction, a better operating reliability and simplified maintenance leading to lower machine manufacturing costs and lower production of filled fillers.

The annular supports of the cams 9 to 14 as well as the means for fixing the latter on said supports are not shown in detail in the appended drawings, being of simple constitution, easily accessible to those skilled in the art.
Ainsi, il est possible de régler de manière précise les différents mouvements des éléments à commander par les cames et plus particulièrement le début et la fin de l'intervention desdites cames.Thus, it is possible to precisely regulate the various movements of the elements to be controlled by the cams and more particularly the start and end of the intervention of said cams.
De cette manière, le fonctionnement de la machine de remplissage peut être garanti avec une grande flexibilité, dans la mesure où le début et la fin de l'exécution des différents mouvements des éléments commandés peut être réglée à loisir, en fonction des exigences spécifiques.In this way, the operation of the filling machine can be guaranteed with great flexibility, insofar as the start and end of the execution of the different movements of the controlled elements can be adjusted at will, according to the specific requirements.
Chaque poste de remplissage 3 est constitué par une tête pivotable 29, montée sur un axe vertical 3', guidé sur le poste de transfert rotatif 1 par l'intermédiaire d'un support fixe 3", monté sur ledit poste 1, ladite tête pivotable 29 étant pourvue d'un pivot d'actionnement excentré 16 coopérant avec un ensemble poussoir 11' - levier coudé 11" - biellette 11'" actionné par une came 11 du dispositif de commande à cames. Le levier coudé 11" est monté de manière pivotante sur le poste de transfert 1 par l'intermédiaire d'un palier 15 et est relié à articulation par ses deux extrémités, respectivement à une extrémité du poussoir 11" opposée à la came 11 et à une extrémité de la biellette 11'", qui est montée à articulation sur le pivot d'actionnement excentré 16 de la tête 29 du poste de remplissage 3.Each filling station 3 is constituted by a pivotable head 29, mounted on a vertical axis 3 ', guided on the rotary transfer station 1 by means of a fixed support 3 ", mounted on said station 1, said pivotable head 29 being provided with an eccentric actuating pivot 16 cooperating with a pusher assembly 11 '- elbow lever 11 "- link 11'" actuated by a cam 11 of the cam control device. The elbow lever 11 "is mounted so pivoting on the transfer station 1 via a bearing 15 and is connected to articulation by its two ends, respectively at one end of the pusher 11 "opposite the cam 11 and at one end of the link 11 '", which is articulated on the eccentric actuating pivot 16 of the head 29 of the filling station 3.
Le poussoir 11' est guidé sur le poste de transfert 1 par l'intermédiaire d'un manchon 18 solidaire de ce dernier et est muni à son extrémité coopérant avec la came 11 d'une roulette d'appui 17, un ressort 19 monté concentriquement sur le poussoir 11' entre le manchon 18 et un épaulement ou une rondelle d'appui située près de la roulette 17 assurant un contact permanent de cette dernière avec la came 11. Ainsi, au cours de la rotation du poste de transfert 1 avec les postes de remplissage 3, les têtes 29 de ces derniers sont actionnées en pivotement entre deux positions extrêmes qui sont délimitées par le profil de la came 11. Comme décrit ci-après, ces positions correspondent respectivement à celle d'arrachage et de pose de l'obturateur avant et après le remplissage et à celle de remplissage de l'outre. Le nombre de postes de remplissage 3 est de quatre sur les dessins annexés. Toutefois, ce nombre peut être différent, les cames 9 à 14 devant simplement tenir compte du nombre de postes de remplissage 3, afin de permettre en une rotation des cames autour de l'axe 2 un cycle complet de fonctionnement des postes 3.The pusher 11 ′ is guided on the transfer station 1 by means of a sleeve 18 integral with the latter and is provided at its end cooperating with the cam 11 with a support wheel 17, a spring 19 mounted concentrically on the pusher 11 'between the sleeve 18 and a shoulder or a support washer located near the wheel 17 ensuring a permanent contact of the latter with the cam 11. Thus, during the rotation of the transfer station 1 with the filling stations 3, the heads 29 of the latter are pivotally actuated between two extreme positions which are delimited by the profile of the cam 11. As described below, these positions correspond respectively to that of tearing off and of fitting the shutter before and after filling and to that of filling the addition. The number of filling stations 3 is four in the accompanying drawings. However, this number may be different, the cams 9 to 14 having to simply take into account the number of filling stations 3, in order to allow the cams to rotate around the axis 2 for a complete operating cycle for the stations 3.
Le moyen 4 de préhension et de maintien de la base d'un obturateur démontable 5 d'une outre 6 de chaque poste de remplissage 3 est constitué par un ensemble de pinces gauche 4' et droite 4" à actionnement différé commandées respectivement par des cames 10 et 9 du dispositif de commande à cames, par l'intermédiaire d'ensembles poussoir 10', 9' - levier coudé 10", 9" - biellette 10'", 9'". Les leviers coudés 10", 9" sont articulés sur le poste de transfert 1 par l'intermédiaire de paliers respectifs 23, 22 et les poussoirs 10", 9" sont guidés sur cedit poste de transfert 1 par l'intermédiaire de manchons 21, 20, lesdits poussoirs étant, en outre, pourvus, d'une part, chacun d'une roulette 27, 26 d'appui sur les cames respectives 10 et 9 et, d'autre part, d'un ressort de compression 25, 24 s'appuyant près de son extrémité portant la roulette d'appui et contre le manchon 21, 20. La liaison articulée entre les pinces gauche 4' et droite 4" et les biellettes 10'", 9'" s'effectue, de manière connue, par l'intermédiaire d'un pivot excentré coopérant avec l'extrémité correspondante de la biellette.The means 4 for gripping and holding the base of a removable shutter 5 of a further 6 of each filling station 3 is constituted by a set of left clamps 4 'and right 4 "with delayed actuation controlled respectively by cams 10 and 9 of the cam control device, by means of push-button assemblies 10 ', 9' - angled lever 10 ", 9" - rod 10 '", 9'". The angled levers 10 ", 9" are articulated on the transfer station 1 by means of respective bearings 23, 22 and the pushers 10 ", 9" are guided on said transfer station 1 by means of sleeves 21, 20, said pushers being, in addition, provided, on the one hand, each with a caster 27, 26 bearing on the respective cams 10 and 9 and, on the other hand, a compression spring 25, 24 bearing near its end carrying the support wheel and against the sleeve 21, 20. The articulated connection between the left 4 'and right 4 "clamps and the rods 10'", 9 '"is e ffectue, in known manner, by means of an eccentric pivot cooperating with the corresponding end of the link.
Ainsi, au cours de la rotation du poste de transfert 1, pour le maintien et le positionnement d'une outre 6, l'une des pinces, à savoir la pince gauche 4' est d'abord poussée dans sa position de service et entoure partiellement la partie inférieure de l'obturateur 5 de ladite outre 6 en amenant cet obturateur dans sa position définitive d'enlèvement et de pose dans la partie supérieure, ainsi que de remplissage, puis, au cours de la poursuite de la rotation du poste 1, l'autre pince, à savoir la pince droite 4", est amenée en position de service, dans laquelle elle sert la partie inférieure de l'obturateur 5 contre la pince gauche 4'. Le maintien de la partie inférieure de l'obturateur 5 et donc de l'outre 6 est assuré pendant toute la durée du remplissage et jusqu'au moment de l'évacuation de l'outre 6. Le moyen 7 de manipulation de la partie supérieure de l'obturateur 5 est constitué par un manchon 28 de préhension de la partie supérieure de l'obturateur 5 monté sur la tête 29 du poste de remplissage 3 avec possibilité de légers déplacements parallèlement à l'axe 3' de support de la tête 29. Ce manchon 28 est monté sur la tête 29 par l'intermédiaire d'un ensemble de guidage à amortissement 30 à 32 (figures 3 et 4) constitué par un axe coulissant 30 chargé par un ressort 31 et par une tige de guidage 32 coopérant avec un guidage correspondant de la tête 29 et maintenant celle-ci contre une rotation autour de l'axe 30. Le manchon 28 est pourvu d'au moins deux pinces à griffes 28' opposées chargées chacune par un ressort (non représenté) de rappel dans une position de fermeture des griffes. Les pinces à griffes 28' sont destinées à saisir, par l'intermédiaire de leurs griffes, le rebord inférieur de la partie supérieure d'un obturateur 5, afin d'en permettre l'arrachage. Un fonctionnement parfait du manchon 28 peut ainsi être assuré du fait du montage de celui-ci sur la tête 29 avec possibilité de légers déplacements en direction de cette dernière par l'intermédiaire de l'ensemble de guidage à amortissement 30 à 32.Thus, during the rotation of the transfer station 1, for the maintenance and positioning of a further 6, one of the clamps, namely the left clamp 4 'is first pushed into its service position and surrounds partially the lower part of the shutter 5 of said addition 6 by bringing this shutter in its final position of removal and installation in the upper part, as well as filling, then, during the continuation of the rotation of the station 1 , the other clamp, namely the right clamp 4 ", is brought into the service position, in which it serves the lower part of the shutter 5 against the left clamp 4 '. Maintaining the lower part of the shutter 5 and therefore of the addition 6 is ensured for the entire duration of filling and until the evacuation of the addition 6. The means 7 for handling the upper part of the shutter 5 is constituted by a sleeve 28 for gripping the upper part of the shutter 5 mounted on the head 29 of the filling station 3 with the possibility of slight movements parallel to the axis 3 'for supporting the head 29. This sleeve 28 is mounted on the head 29 by means of a damping guide assembly 30 to 32 (FIGS. 3 and 4) constituted by a sliding axis 30 loaded by a spring 31 and by a guide rod 32 cooperating with a corresponding guide of the head 29 and holding the latter against a rotation about the axis 30. The sleeve 28 is provided with at least two claw pliers 28 'opposite each loaded by a return spring (not shown) in a position for closing the claws. The claw pliers 28 ′ are intended to grip, by means of their claws, the lower rim of the upper part of a shutter 5, in order to allow it to be pulled out. Perfect operation of the sleeve 28 can thus be ensured due to the mounting of the latter on the head 29 with the possibility of slight displacements in the direction of the latter via the damping guide assembly 30 to 32.
Selon une autre caractéristique de l'invention, l'axe 3' de chaque poste de remplissage 3, qui est guidé sur le support fixe 3" solidaire du poste de transfert 1, traverse ledit poste de transfert 1 et coopère à son extrémité libre opposée à la tête 29 avec une came annulaire 12 de l'ensemble de commande à cames 9 à 14. A cet effet, l'extrémité libre de l'axe 3' est avantageusement pourvue de deux ergots ou roulettes de guidage 3'" s'appuyant de part et d'autre de la came annulaire 12.According to another characteristic of the invention, the axis 3 'of each filling station 3, which is guided on the fixed support 3 "integral with the transfer station 1, passes through said transfer station 1 and cooperates at its opposite free end at the head 29 with an annular cam 12 of the cam control assembly 9 to 14. For this purpose, the free end of the axis 3 'is advantageously provided with two lugs or guide rollers 3' "s" pressing on either side of the annular cam 12.
Ainsi, lors de la rotation du poste de transfert 1, l'axe 3', qui coopère avec la came 12 par l'intermédiaire de ses ergots ou roulettes 3'", est affecté d'un déplacement vertical montant et descendant, dans lequel il entraîne la tête 29 et donc le manchon 28. Pour effectuer l'arrachage de la partie supérieure d'un obturateurThus, during the rotation of the transfer station 1, the axis 3 ', which cooperates with the cam 12 by means of its lugs or rollers 3' ", is affected by a vertical movement up and down, in which it drives the head 29 and therefore the sleeve 28. To pull out the upper part of a shutter
5, dans la position de pivotement correspondante de la tête 29 du poste 3, suite à l'actionnement de cette dernière par l'intermédiaire de la came 11, la came 12 actionne ladite tête 29 dans un mouvement de descente ayant pour conséquence d'appliquer le manchon 28 du moyen 7 de manipulation de la partie supérieure de l'obturateur 5, sur ledit obturateur 5 et à réaliser un encliquetage des griffes des pinces à griffes 28' sous le rebord de ladite partie supérieure. Il s'ensuit que, lors de la rotation consécutive du poste de travail 1, la came 12 repousse l'axe 3' de support de la tête 29 en sens contraire et provoque l'arrachage de ladite partie supérieure de l'obturateur, qui reste maintenue dans le manchon 28. L'ensemble de guidage à amortissement 30 à 32 du manchon 28 permet d'assurer avec certitude la prise de la partie supérieure de l'obturateur, tout en évitant un écrasement de celui-ci sous l'effet du mouvement de descente de la tête 29.5, in the corresponding pivoting position of the head 29 of the station 3, following the actuation of the latter via the cam 11, the cam 12 actuates the said head 29 in a downward movement having the consequence of apply the sleeve 28 of the means 7 for handling the upper part of the shutter 5, on said shutter 5 and to snap the claws of the claw pliers 28 'under the rim of said upper part. It follows that, during the consecutive rotation of the work 1, the cam 12 pushes the axis 3 ′ for supporting the head 29 in the opposite direction and causes the lifting of said upper part of the shutter, which remains held in the sleeve 28. The damping guide assembly 30 to 32 of the sleeve 28 ensures with certainty the grip of the upper part of the shutter, while preventing it from being crushed under the effect of the downward movement of the head 29.
Le dispositif de remplissage 8, coopérant avec l'orifice de l'obturateur 5, est monté sur la tête mobile 29 du poste 3 et est déplaçable en pivotement, ensemble avec le moyen 7 de manipulation de la partie supérieure de l'obturateur 5, et se présente sous forme d'un corps creux pouvant être appliqué de manière étanche sur la partie inférieure de l'obturateur 5, ce corps creux étant, d'une part, relié par un raccord 33 à une conduite 34 de liaison à la pompe de remplissage reliée à un réservoir et, d'autre part, pourvu d'un moyen d'obturation du raccord 33 commandé par un vérin pneumatique 35 (figures 1, 2 et 4).The filling device 8, cooperating with the orifice of the shutter 5, is mounted on the movable head 29 of the station 3 and is pivotally displaceable, together with the means 7 for handling the upper part of the shutter 5, and is in the form of a hollow body which can be applied in leaktight manner to the lower part of the shutter 5, this hollow body being, on the one hand, connected by a connector 33 to a pipe 34 for connection to the pump filling connected to a tank and, on the other hand, provided with a means for closing the connector 33 controlled by a pneumatic cylinder 35 (Figures 1, 2 and 4).
Ainsi, après arrachage de la partie supérieure de l'obturateur 5 au moyen du manchon 28 commandé par la came 12, la tête 29 du poste 3 est pivotée dans la position de remplissage de l'outre 6 par la came 11 et le dispositif de remplissage 8 est appliqué de manière étanche sur la base de l'obturateur 5 dans un mouvement commandé par la came 12.Thus, after tearing off the upper part of the shutter 5 by means of the sleeve 28 controlled by the cam 12, the head 29 of the station 3 is pivoted into the filling position of the addition 6 by the cam 11 and the filling 8 is applied sealingly to the base of the shutter 5 in a movement controlled by the cam 12.
Une simple détection de cette application par un contact de fin de course intégré au dispositif 8 permet l'actionnement du vérin 35 pendant une durée correspondant au remplissage de l'outre 6. Cette durée peut être parfaitement prédéterminée et contrôlée par une minuterie, qui actionne le vérin 35 à la fermeture, à la fin du remplissage.A simple detection of this application by a limit switch integrated into the device 8 allows actuation of the jack 35 for a period corresponding to the filling of the bottle 6. This period can be perfectly predetermined and controlled by a timer, which activates the jack 35 when closing, at the end of filling.
Conformément une caractéristique de l'invention, le poste de transfert 1 est pourvu, au niveau de chaque poste de remplissage 3, d'un moyen 36 de support, d'obturation et d'évacuation des outres 6, qui est essentiellement constitué par un dispositif pivotant 37 de réception des outres coopérant avec une came de commande 14 et par un ensemble 38 d'obturation des outres 6 après remplissage, coopérant avec une came de commande 13 (figures 3 et 4).According to a characteristic of the invention, the transfer station 1 is provided, at each filling station 3, with a means 36 for supporting, closing and evacuating the bottles 6, which is essentially constituted by a pivoting device 37 for receiving the wineskins cooperating with a control cam 14 and by a set 38 for closing the bottles 6 after filling, cooperating with a control cam 13 (FIGS. 3 and 4).
Le dispositif pivotant 37 de réception des outres coopérant avec une came de commande 14 se présente sous forme d'une plaque de support pivotante 37' montée à articulation sur le poste de transfert 1 par l'intermédiaire d'un arbre de pivotement 37" et par un bras d'actionnement 37'", solidaire de la plaque de support pivotante 37' et coopérant à son extrémité libre, par l'intermédiaire d'une roulette ou analogue 39, avec la came 14 du dispositif de commande à cames. Ainsi, l'outre 6 peut être déposée à vide et à plat, comme représenté aux figures 1 et 2 des dessins annexés et être saisie et positionnée, puis remplie pour être finalement évacuée, après remplissage et remise en place de l'obturateur, en étant maintenue à plat pendant l'opération de positionnement, ainsi que pendant le remplissage et l'obturation, un pivotement de la plaque 37' s'effectuant après ladite obturation, lorsque le bras d'actionnement 37'" arrive sur le profil correspondant de la came 14. En effet, à ce moment, le bras 37'", dont la longueur est immuable, n'est plus maintenu dans une position permettant à la plaque 37' d'être horizontale, de sorte que ladite plaque pivote dans une position oblique d'évacuation de l'outre 6. Lorsque le bras 37'" rencontre à nouveau un obstacle du profil de la came 14, il est repoussé de telle manière qu'il provoque un pivotement de la plaque 37' vers sa position de service à l'horizontale.The swivel device 37 for receiving the wineskins cooperating with a control cam 14 is in the form of a swivel support plate 37 ′ hingedly mounted on the transfer station 1 by means of a swivel shaft 37 "and by an actuating arm 37 '", integral with the pivoting support plate 37' and cooperating in its free end, via a caster or the like 39, with the cam 14 of the cam control device. Thus, the addition 6 can be placed empty and flat, as shown in Figures 1 and 2 of the accompanying drawings and be gripped and positioned, then filled to be finally evacuated, after filling and replacing the shutter, being kept flat during the positioning operation, as well as during filling and closing, a pivoting of the plate 37 'takes place after said closing, when the actuating arm 37'"arrives on the corresponding profile of the cam 14. Indeed, at this moment, the arm 37 ′ ″, the length of which is immutable, is no longer maintained in a position allowing the plate 37 ′ to be horizontal, so that said plate pivots in a oblique evacuation position of the bottle 6. When the arm 37 '"again encounters an obstacle in the profile of the cam 14, it is pushed back so that it causes the plate 37' to pivot towards its position horizontal service.
L'ensemble 38 d'obturation des outres 6 après remplissage se présente sous forme d'une platine d'appui 38' logée dans un évidement de forme correspondante de la plaque de support pivotante 37', cette platine 38' étant solidarisée avec un poussoir 38" guidé sous la plaque 37' dans un manchon 40 solidaire de cette dernière et s'appuyant par son extrémité opposée par l'intermédiaire d'une roulette ou analogue 41 sur la came 13 du dispositif de commande à cames, un ressort de compression 42, monté entre le manchon 40 et l'extrémité du poussoir 38" portant la roulette 41, assurant un appui permanent dudit poussoir 38" sur ladite came 13. Grâce à ce mode de réalisation de l'ensemble 38, il est possible d'assurer un maintien de l'outre 6, du côté opposé à l'obturateur 5, pour favoriser la mise en place par pression de la partie supérieure dudit obturateur 5 après le remplissage de l'outre 6, par l'intermédiaire du manchon 28 du moyen de manipulation 7.The assembly 38 for closing the bottles 6 after filling is in the form of a support plate 38 'housed in a recess of corresponding shape of the pivoting support plate 37', this plate 38 'being secured to a pusher 38 "guided under the plate 37 'in a sleeve 40 integral with the latter and bearing at its opposite end by means of a roller or the like 41 on the cam 13 of the cam control device, a compression spring 42, mounted between the sleeve 40 and the end of the pusher 38 "carrying the caster 41, ensuring permanent support of said pusher 38" on said cam 13. Thanks to this embodiment of the assembly 38, it is possible to maintain the addition 6, on the side opposite the shutter 5, to favor the positioning by pressure of the upper part of said shutter 5 after filling the addition 6, by means of the sleeve 28 of the handling means 7.
De préférence, selon une autre caractéristique de l'invention, le manchon 40 de guidage du poussoir 38" de l'ensemble d'obturation 38 fait partie intégrante du bras d'actionnement 37'", ce dernier étant solidarisé avec ledit manchon 40 de manière excentrée par rapport à l'axe du poussoir 38" (figure 4).Preferably, according to another characteristic of the invention, the sleeve 40 for guiding the pusher 38 "of the shutter assembly 38 is an integral part of the actuating arm 37 '", the latter being secured to said sleeve 40 of eccentrically to the axis of the 38 "pusher (Figure 4).
Selon une autre caractéristique de l'invention, l'entraînement de la machine de remplissage est assuré par l'intermédiaire d'un moteur électrique contrôlé au moyen d'un circuit électronique de commande. Ce circuit électronique de commande n'est pas décrit plus en détail et relève d'une technologie connue. Ainsi, l'énergie nécessaire au fonctionnement de la machine est utilisée directement sans nécessité de transformation annexe, comme cela est le cas dans le cas de l'utilisation de moyens d'actionnement pneumatique ou autre, de sorte que le rendement énergétique est plus élevé. Grâce à l'invention, il est possible de réaliser en un cycle continu et automatique un remplissage d'outrés, ce en effectuant l'ensemble des opérations nécessaires par l'intermédiaire d'une commande à cames de fonctionnement particulièrement fiable et ne nécessitant aucun dispositif de détection de position. En outre, cette commande entièrement mécanique permet un fonctionnement synchrone sans risque de déréglage sur un temps de fonctionnement long.According to another characteristic of the invention, the filling machine is driven by an electric motor controlled by means of an electronic control circuit. This electronic control circuit is not described in more detail and is of a known technology. Thus, the energy necessary for the operation of the machine is used directly without the need for additional processing, as is the case in the case of the use of pneumatic or other actuation means, so that the energy efficiency is higher . Thanks to the invention, it is possible to carry out in a continuous and automatic cycle a filling of bottles, by carrying out all the necessary operations by means of a particularly reliable operating cam control and requiring no position detection device. In addition, this fully mechanical control allows synchronous operation without risk of adjustment over a long operating time.
De plus, il est possible d'effectuer sur chaque poste de remplissage 3 toutes les opérations relatives au remplissage d'une outre, de sorte que le rendement de la machine de remplissage peut être considérablement augmenté, lesdites opérations s'effectuant en continu. Il en résulte d'importants gains de productivité.In addition, it is possible to carry out on each filling station 3 all the operations relating to the filling of a further, so that the efficiency of the filling machine can be considerably increased, said operations being carried out continuously. This results in significant productivity gains.
Par ailleurs, la prévision d'une commande de l'ensemble des opérations quasi exclusivement par l'intermédiaire de cames permet une simplification importante de la construction et du fonctionnement de la machine, ainsi qu'une amélioration de sa fiabilité, en particulier par réduction du temps de maintenance, et donc des frais de maintenance.Furthermore, the provision of an order for all of the operations almost exclusively by means of cams allows a significant simplification of the construction and operation of the machine, as well as an improvement of its reliability, in particular by reduction maintenance time, and therefore maintenance costs.
De plus, la productivité de la machine peut être améliorée par prise en compte des accélérations positives et négatives des mouvements des différents éléments, afin d'optimiser le fonctionnement de la machine. Enfin, la disposition des cames conformément à l'invention entraîne une grande compacité de la machine de remplissage tout en évitant des contacts entre les parties mécaniques d'actionnement, éventuellement lubrifiées, et les postes de remplissage, de sorte que des conditions d'hygiène parfaite sont garanties. Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. In addition, the productivity of the machine can be improved by taking into account positive and negative accelerations of the movements of the various elements, in order to optimize the operation of the machine. Finally, the arrangement of the cams in accordance with the invention results in a great compactness of the filling machine while avoiding contact between the mechanical actuating parts, possibly lubricated, and the filling stations, so that hygienic conditions perfect are guaranteed. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
