Description

DISPOSITIF POUR L'EXTRACTION DU CONTENU DES ALVEOLES D'UNE PLAQUETTE-EMBALLAGE DANS UNE INSTALLATION DE CONDITIONNEMENT La présente invention se rapporte à un dispositif pour l'extraction du contenu des alvéoles d'une plaquette- emballage dans une installation de conditionnement. Elle concerne donc le conditionnement automatique d'objets divers, déposés seuls, ou en combinaison avec d'autres objets, dans les alvéoles d'une matrice, ultérieurement recouverte par un film, collé ou scellé sur elle, puis découpé en plaquettes.The present invention relates to a device for extracting the contents of the alveoli from a packaging wafer in a packaging installation. It therefore relates to the automatic packaging of various objects, deposited alone, or in combination with other objects, in the cells of a matrix, subsequently covered by a film, glued or sealed on it, then cut into plates.
Bien que visant plus spécialement le conditionnement dans 1*industrie pharmaceutique de gélules, de dragées, de cachets, de comprimés, et même de doses de poudre, l'invention s'étend au conditionnement de tout produit alimentaire, tels que bonbons et dragées, et même de tous objets, tels que petits articles de quincaillerie.Although more specifically targeting the packaging in the pharmaceutical industry of capsules, dragees, cachets, tablets, and even doses of powder, the invention extends to the packaging of any food product, such as sweets and dragees, and even all objects, such as small hardware items.
Dans ce type d'installation, une feuille en matière synthétique est d'abord conformée pour présenter transversalement des rangées parallèles d'alvéoles, puis est amenée à un poste de remplissage déposant, dans chacune des alvéoles d'une rangée, un ou plusieurs objets ou dose, puis est obturée par un film plan, métallique ou en matière synthétique, collé ou scellé sur elle.In this type of installation, a plastic sheet is first shaped to present transversely parallel rows of cells, then is brought to a filling station depositing, in each of the cells of a row, one or more objects or dose, then is closed by a flat, metallic or synthetic film, glued or sealed on it.
Pour éviter que, en raison d'incidents de distribution, le remplissage des alvéoles d'une rampe ne soit pas satisfaisant, en quantité et/ou qualité, et par exemple que certaines alvéoles soient vides ou au contraire contiennent seulement des fragments des objets, il est connu par DE-A- 1 955 359 et par EP-A-401 103 de faire passer chaque rangée sous une barrière de détection réagissant sur un dispositif, disposé en aval, d'évacuation du contenu des rangées incomplètes ou insatisfaisantes en qualité. Dans DE-A-1 955 359, le dispositif d'évacuation est composé de buses d'aspiration qui, en même nombre que les alvéoles d'une rangée au-dessus desquelles elles sont disposées, sont alimentées en permanence et sont munies chacune d'un clapet d'obturation dont l'ouverture est commandée par les moyens de détection.To avoid that, due to distribution incidents, the filling of the cells of a ramp is not satisfactory, in quantity and / or quality, and for example that certain cells are empty or, on the contrary, contain only fragments of the objects, it is known from DE-A-1 955 359 and from EP-A-401 103 to pass each row under a detection barrier reacting on a device, disposed downstream, for evacuating the content of the rows incomplete or unsatisfactory in quality . In DE-A-1 955 359, the evacuation device is composed of suction nozzles which, in the same number as the cells of a row above which they are arranged, are continuously supplied and are each provided with 'A shutter valve whose opening is controlled by the detection means.
Dans EP-A-401 103, le dispositif d'évacuation met aussi en oeuvre une aspiration permanente pour vider toutes les alvéoles d'une rangée, mais cette aspiration est orientée par un volet, mobile verticalement entre un corps et une plaque de guidage, et pouvant occuper, une position supérieure, dans laquelle il dégage l'orifice d'entrée d'une chambre d'extraction et oriente le flux d'aspiration en direction de la rangée sous-jacente d'alvéoles, et une position inférieure d'obturation dans laquelle il vient à proximité de la matrice et par une ouverture, le traversant et communiquant avec une ouverture de la plaque de guidage, oriente le flux d'aspiration hors des alvéoles. Ce dispositif supprime les variations brutales du débit d'aspiration, mais aussi les turbulences dans la zone d'extraction et permet de véhiculer les produits extraits des alvéoles dans des conditions évitant leur destruction, ce qui est particulièrement intéressant pour les comprimés ou équivalents.In EP-A-401 103, the evacuation device also implements a permanent suction to empty all the cells of a row, but this aspiration is oriented by a flap, movable vertically between a body and a guide plate, and being able to occupy, an upper position, in which it clears the entry orifice of an extraction chamber and directs the suction flow towards the underlying row of cells, and a lower position of obturation in which it comes close to the matrix and through an opening, passing through it and communicating with an opening of the guide plate, orients the suction flow out of the cells. This device eliminates sudden variations in the suction flow rate, but also turbulence in the extraction zone and makes it possible to transport the products extracted from the alveoli under conditions preventing their destruction, which is particularly advantageous for tablets or the like.
Si un tel dispositif d'extraction donne entière satisfaction pour des objets standards, et en particulier pour des comprimés de forme circulaire, il s'avère insuffisant lorsque les objets ont des formes allongées, ou sont disposées dans des alvéoles inclinées par rapport à la trajectoire de déplacement de la matrice ou sont lourds et en particulier ont un poids unitaire dépassant 500 mg.If such an extraction device is entirely satisfactory for standard objects, and in particular for tablets of circular shape, it turns out to be insufficient when the objects have elongated shapes, or are arranged in cells inclined relative to the trajectory. displacement of the matrix or are heavy and in particular have a unit weight exceeding 500 mg.
La présente invention a pour objet de remédier à ces inconvénients en perfectionnant le dispositif décrit dans EP-A-407 103, de manière qu'il assure une totale extraction des alvéoles d'une rangée, quels que soit le poids et la forme des objets, mais aussi l'orientation des alvéoles, tout en permettant une cadence de production plus élevée. A cet effet, dans le dispositif selon l'invention, une barrette amont du corps venant en appui sur la matrice alvéolée avant l'ouverture d'extraction comporte, d'une part, une chambre interne raccordée à une source d'air comprimé, avec interposition d'une électrovanne reliée à un boîtier de commande, et, d'autre part, au moins une buse de soufflage communiquant avec la chambre interne, et apte à débiter vers le bas et l'aval, un jet d'air sous pression traversant l'ouverture d'extraction du corps et pénétrant dans les alvéoles pour en chasser le contenu. Grâce à cet agencement, lorsque la barrière de détection détecte, dans les alvéoles d'une rangée, par exemple une absence de comprimés, les moyens de commande de l'installation réagissent, lorsque la rampe défaillante parvient sous l'ouverture d'extraction, sur les moyens moteurs du volet pour l'amener, de sa position inférieure d'obturation à sa position supérieure d'extraction et, simultanément, commandent l'électrovanne du circuit d'air comprimé.The object of the present invention is to remedy these drawbacks by improving the device described in EP-A-407 103, so that it provides total extraction of the cells in a row, whatever the weight and shape of the objects, but also the orientation of the cells, while allowing a higher production rate. To this end, in the device according to the invention, an upstream bar of the body coming to bear on the honeycomb matrix before the extraction opening comprises, on the one hand, an internal chamber connected to a source of compressed air, with the interposition of a solenoid valve connected to a control unit, and, on the other hand, at least one blowing nozzle communicating with the internal chamber, and capable of delivering downward and downstream, a jet of air under pressure passing through the extraction opening of the body and entering the alveoli to expel the contents. Thanks to this arrangement, when the detection barrier detects, in the cells of a row, for example an absence of tablets, the installation control means react, when the faulty ramp reaches under the extraction opening, on the shutter motor means to bring it from its lower closed position to its upper extraction position and, simultaneously, control the solenoid valve of the compressed air circuit.
Il en résulte que toutes les alvéoles de la rangée considérée sont soumises à un jet d'air sous pression qui éjecte leur contenu hors de l'alvéole, donc vers l'aval où ils sont immédiatement repris par le flux d'aspiration provenant de la chambre d'extraction. Dans cette chambre, ils sont évacuées par le circuit d'extraction en direction d'un récipient qui les recueille.As a result, all the cells of the row in question are subjected to a jet of pressurized air which ejects their contents out of the cell, therefore downstream where they are immediately taken up by the suction flow coming from the extraction chamber. In this chamber, they are evacuated by the extraction circuit towards a container which collects them.
La combinaison des jets d'air comprimé avec l'aspiration permet de vider, totalement et rapidement, toutes les alvéoles quelle que soit la nature de leur contenu. Selon la forme et la masse des objets, les jets d'air sous pression peuvent être déclenchés avant, pendant ou après le mouvement vertical du volet assurant l'inversion de l'orientation du flux d'aspiration.The combination of the compressed air jets with the suction makes it possible to empty, completely and quickly, all the cells whatever the nature of their content. Depending on the shape and mass of the objects, the pressurized air jets can be triggered before, during or after the vertical movement of the flap ensuring the reversal of the orientation of the suction flow.
Dans une forme d'exécution de l'invention, la barrette comporte autant de buses qu'une rangée de la matrice alvéolée comporte d'alvéoles, et chacune des buses est orientée dans le plan horizontal pour débiter un jet qui est parallèle à l'axe longitudinal de l'alvéole correspondante.In one embodiment of the invention, the bar has as many nozzles as a row of the honeycomb matrix has cells, and each of the nozzles is oriented in the horizontal plane to deliver a jet which is parallel to the longitudinal axis of the corresponding cell.
Cette disposition favorise l'éjection des corps longs, sans engendrer de grande perturbation aéraulique.This arrangement favors the ejection of long bodies, without causing great ventilation disturbance.
Avantageusement, la barrette est munie d'une face supérieure qui, au moins dans sa partie aval, est pentue vers le bas et l'aval, et qui, en phase d'extraction, coopère avec la face inférieure également en pente, de haut en bas vers l'aval, d'un redan ménagé à la base du volet et saillant, en amont de ce volet, pour canaliser le flux d'aspiration vers l'ouverture d'extraction du corps.Advantageously, the bar is provided with an upper face which, at least in its downstream part, slopes downwards and downstream, and which, in the extraction phase, cooperates with the lower face also in slope, from high downstream downstream, a step formed at the base of the flap and projecting, upstream of this flap, to channel the suction flow towards the extraction opening of the body.
Avec cet aménagement, lorsque le volet est en position d'extraction, c'est à dire est soulevé pour orienter le flux d'aspiration provenant de la chambre d'extraction en direction de l'ouverture du corps, la face inférieure de son redan forme, avec la face en vis à vis de la barrette, un canal d'aspiration de l'air extérieur orientant ce flux d'entrée vers la matrice alvéolée, et plus spécialement vers la rangée d'alvéoles apparaissant à travers l'ouverture du corps, afin de mieux entraîner les produits extraits des alvéoles par les jets d'air comprimé.With this arrangement, when the flap is in the extraction position, that is to say is raised to direct the suction flow from the extraction chamber towards the opening of the body, the lower face of its step forms, with the face opposite the bar, a suction channel for the outside air directing this inlet flow towards the honeycomb matrix, and more particularly towards the row of cells appearing through the opening of the body, in order to better entrain the products extracted from the alveoli by the jets of compressed air.
Avantageusement, le circuit d'aspiration aboutissant dans la chambre d'extraction communique avec un canal de perte de charge obturé par une électrovanne régie par le boîtier de commande.Advantageously, the suction circuit terminating in the extraction chamber communicates with a pressure drop channel closed by a solenoid valve governed by the control unit.
Avec cet aménagement, dès que le contenu des alvéoles est extrait de celle-ci et pénètre dans la chambre d'extraction, le boîtier de commande actionne l'électrovanne dans le sens de l'ouverture du canal de perte de charge, afin de réduire la vitesse du flux d'aspiration dans le circuit correspondant et, en conséquence, réduire les risques de détérioration des produits extraits par choc à grande vitesse contre les parois du circuit.With this arrangement, as soon as the contents of the cells are extracted therefrom and enters the extraction chamber, the control unit actuates the solenoid valve in the direction of opening of the pressure drop, in order to reduce the speed of the suction flow in the corresponding circuit and, consequently, reduce the risk of deterioration of the products extracted by high speed impact against the walls of the circuit.
D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution du dispositif selon l'invention.Other characteristics and advantages will emerge from the description which follows with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of the device according to the invention.

Ce dernier poste est suivi d'un poste F de sélection envoyant les plaquettes correctement chargées sur un convoyeur d'évacuation G et éjectant les plaquettes vides dans un récipient H. Le poste C d'extraction des objets disposés dans une rangée d'alvéoles incorrectement remplie, comporte une ouverture d'extraction séparée par un pas P de la barrière de détection B et est relié par un conduit 6 à un récipient 7, dont la partie supérieure est raccordée par un conduit 8 à une source d•aspiration et dont la partie inférieure est obturée par un clapet articulé 9. Lorsque le récipient 7 est plein, le clapet 9 libère son ouverture inférieure de manière que son contenu se dévide par une table de triage J où les produits et, par exemple, les comprimés en bon état sont retournés au poste A de distribution, tandis que ceux en mauvais état sont envoyés dans un récipient K. Tous ces éléments et le processus de fonctionnement de l'installation sont décrits dans EP-A-401 103.As shown in Figure 1, the installation for packaging in wafer-packaging 2 of various products or objects, comprises, above the path of movement of a honeycomb matrix 3 provided with transverse rows of cells 4 at a station A for the distribution of objects, a station B for detecting the filling conditions of the cells 4 of each row, a station C for extraction by suction of the badly filled rows, a station D for positioning and fixing by gluing or welding d '' a flat film 5 for closing the cells and a station E for sectioning each wafer 2. The latter post is followed by a selection station F sending the correctly loaded platelets on an evacuation conveyor G and ejecting the empty platelets in a container H. The station C for extracting objects placed in an incorrectly filled row of cells, comprises a separate discharge opening by a pitch P of the detection of barrier B and is connected by a conduit 6 to a vessel 7, the upper portion is connected via a conduit 8 to a source of suction and • the lower portion is closed by an articulated valve 9. When the container 7 is full, the valve 9 releases its lower opening so that its contents are unwound by a sorting table J where the products and, for example, the tablets in good condition are returned at distribution station A, while those in poor condition are sent to a container K. All these elements and the operation process of the installation are described in EP-A-401 103.
De même, comme dans EP-A-401 103, le dispositif d'extraction représenté à la figure 2, est composé d'un corps fixe 10 dont la face inférieure 12 venant en contact de glissement avec la face supérieure de la matrice alvéolée 3, est pourvue d'une ouverture transversale 13 ayant une largeur et une longueur au moins égale à la largeur et à la longueur d'une rangée d'alvéoles 4, mais pouvant être supérieure, comme montré à la figure 5. Dans la partie aval de ce corps, est aménagée une chambre d'extraction 14 qui est raccordée à une source d'aspiration, par l'intermédiaire du conduit 6 du récipient 7 et du conduit 8 de figure 1. Cette chambre communique, par un canal 15, de longueur égale à celle de l'ouverture 13, avec la partie amont du corps et plus précisément débouche à proximité de 1 'ouverture 13.Similarly, as in EP-A-401 103, the extraction device shown in FIG. 2, is composed of a fixed body 10, the lower face 12 of which comes into sliding contact with the upper face of the honeycomb matrix 3 , is provided with a transverse opening 13 having a width and a length at least equal to the width and the length of a row of cells 4, but which may be greater, as shown in FIG. 5. In the downstream part from this body, an extraction chamber 14 is arranged which is connected to a suction source, via the conduit 6 of the container 7 and the conduit 8 of FIG. 1. This chamber communicates, through a channel 15, from length equal to that of the opening 13, with the upstream part of the body and more precisely opens near the opening 13.
Au moins un volet 16 est monté coulissant dans un couloir vertical délimité entre la face amont du corps 10 et une plaque de guidage 17 rapportée contre ce corps. Comme montré à la figure 3, la plaque 17 comporte, à sa base, une ouverture 18 délimitant le couloir d'aspiration d'entrée. Le volet 16 est relié par une chape 19 à la tige 20a d'un vérin pneumatique dont le corps 20b est fixé sur une console du corps 10. A proximité de son extrémité inférieure, le volet est doté d'au moins une ouverture 22, en l'occurrence trois dans la forme d'exécution.At least one flap 16 is slidably mounted in a vertical corridor delimited between the upstream face of the body 10 and a guide plate 17 attached against this body. As shown in Figure 3, the plate 17 has, at its base, an opening 18 defining the inlet suction passage. The shutter 16 is connected by a yoke 19 to the rod 20a of a pneumatic jack, the body 20b of which is fixed on a console of the body 10. Near its lower end, the shutter is provided with at least one opening 22, in this case three in the form of execution.
Enfin, le corps 10 est solidaire d'une barrette amont 23 dont la face inférieure 23a vient également en contact avec la face supérieure de la matrice alvéolée 3.Finally, the body 10 is integral with an upstream bar 23 whose lower face 23a also comes into contact with the upper face of the honeycomb matrix 3.
Selon l'invention, la barrette amont 23 comporte une chambre interne 24 qui est raccordée par un circuit 25 avec interposition d'un distributeur électromagnétique 26 à une source 27 d'air comprimé. Dans la forme d'exécution représentée, cette chambre communique avec des canaux 28 dont l'extrémité libre forme buse de soufflage. Ces canaux sont en même nombre que les alvéoles dans une rangée d'alvéoles de la matrice 3. Les buses sont disposées et orientées de manière à émettre un jet d'air, représenté en 29 à la figure 4, passant à travers l'ouverture inférieure 13 du corps et pénétrant dans des alvéoles 4 de la rangée au poste d'extraction C. L'angulation, dans le plan vertical de l'axe des canaux 28 dépend de la forme des alvéoles 4, et de la forme et de la masse des objets 1 contenus dans chacune d'elles. De même l'angulation dans le plan horizontal dépend de la forme des objets. Ainsi, pour des objets cylindriques, l'axe de chaque canal est dans un plan parallèle au plan médian longitudinal de l'installation, tandis que, avec des objets allongés 30, par exemple des comprimés allongés disposés dans des alvéoles dont l'axe longitudinal est incliné par rapport à la trajectoire de déplacement de la matrice alvéolée 3, comme montré à la figure 5, l'axe longitudinal des canaux 28 est disposé de manière à être sensiblement parallèle et voire même co-axial à l'axe longitudinal de l'alvéole 4 correspondante. En raison de cette adaptation spécifique à chaque fabrication, la barrette 23 est interchangeable, au même titre que la plaque 17 délimitant le couloir d'entrée du flux d'aspiration. Dans une variante, non représentée, la chambre 24 communique avec un seul canal débitant une lame d'air qui s'étend sur toute la largeur de la rangée d'alvéoles et qui est perpendiculaire à cette matrice alvéolée 3.According to the invention, the upstream bar 23 has an internal chamber 24 which is connected by a circuit 25 with the interposition of an electromagnetic distributor 26 to a source 27 of compressed air. In the embodiment shown, this chamber communicates with channels 28, the free end of which forms a blowing nozzle. These channels are the same number as the cells in a row of cells in the matrix 3. The nozzles are arranged and oriented so as to emit an air jet, represented at 29 in FIG. 4, passing through the opening lower 13 of the body and penetrating into cells 4 of the row at extraction station C. The angulation, in the vertical plane of the axis of the channels 28 depends on the shape of the cells 4, and on the shape and the mass of the objects 1 contained in each of them. Similarly the angulation in the horizontal plane depends on the shape of the objects. Thus, for cylindrical objects, the axis of each channel is in a plane parallel to the longitudinal median plane of the installation, while, with elongated objects 30, for example elongated tablets placed in cells whose longitudinal axis is inclined relative to the path of movement of the honeycomb matrix 3, as shown in FIG. 5, the longitudinal axis of the channels 28 is arranged so as to be substantially parallel and even even co-axial to the longitudinal axis of the 'corresponding cell 4. Because of this specific adaptation to each production, the bar 23 is interchangeable, in the same way as the plate 17 delimiting the inlet corridor of the suction flow. In a variant, not shown, the chamber 24 communicates with a single channel delivering an air space which extends over the entire width of the row of cells and which is perpendicular to this honeycomb matrix 3.
Comme le montre la figure 2, la barrette 3 est munie, en amont de sa face inférieure 23a, d'une face pentue 23b formant rampe de repositionnement des objets dans les alvéoles. Par ailleurs, cette barrette est munie, au moins sur la partie aval de sa face supérieure, d'une face 23c qui est pentue en allant du haut vers le bas et vers l'aval et dont l'utilité sera précisée plus loin.As shown in FIG. 2, the bar 3 is provided, upstream of its lower face 23a, with a sloping face 23b forming a ramp for repositioning objects in the cells. Furthermore, this bar is provided, at least on the downstream part of its upper face, with a face 23c which is sloping from top to bottom and downstream and whose usefulness will be specified below.
Dans le dispositif représenté, le volet 16 est muni à sa partie inférieure et en dessous des ouvertures 22, d'un redan 32 saillant sur l'amont et comportant une face inférieure pentue 32a allant de haut en bas vers l'amont. Cette face peut être plane ou convexe.In the device shown, the flap 16 is provided at its lower part and below the openings 22, with a step 32 projecting upstream and comprising a sloping lower face 32a going from top to bottom upstream. This face can be flat or convex.
Quelle que soit la forme de cette face, le volet comporte en partie inférieure une portée 16b de faible largeur, de l'ordre de 1 mm, suffisante pour assurer l'étanchéité avec l'intervalle entre rangée d'alvéoles de la matrice 3 tout en favorisant la sélection entre rangées.Whatever the shape of this face, the flap has in the lower part a span 16b of small width, of the order of 1 mm, sufficient to ensure sealing with the interval between row of cells of the matrix 3 while by favoring the selection between rows.
Lorsque le dispositif d'extraction est au repos, le volet 16 est en position inférieure, c'est à dire est amené par le vérin jusqu'à ce que sa face inférieure vienne en contact de la matrice alvéolée 3, comme montré figure 4. Dans cette position, le volet obture la partie inférieure du canal 15 et, par les ouvertures 22 ménagées à travers lui, crée un flux d'aspiration qui, comme montré par la flèche 33 à la figure 4, circule dans la partie supérieure du couloir d'entrée 18 et est sans effet sur les objets 1 disposés dans les alvéoles 4, au-dessous de l'ouverture 13. Dans cette position, la face inclinée 32a du redan 32 assure le repositionnement des objets 1 contenus dans les alvéoles et qui, pourraient être partiellement soulevés par l'aspiration. Lorsque la barrière de détection B a détecté une anomalie dans =. l'une des rangées d'alvéoles, cette information est mémorisée dans un boîtier de commande 34 jusqu'à ce que la rangée correspondante parvienne, par déplacement pas à pas, au niveau de l'ouverture 13. Dans ces conditions, le boîtier de commande 34 commande, d'une part, par le distributeur 26 l'alimentation en air comprimé du réseau de soufflage, et d'autre part, par un distributeur 35 l'alimentation du vérin 20b dans le sens de l'élévation de sa tige 20a. Il en résulte que les canaux 28 débitent, dans chaque alvéole, un jet d'air sous pression pénétrant dans l'alvéole et en chassant le contenu à l'extérieur comme montré pour un comprimé 1 à la figure 2. Dès que le comprimé est extrait de l'alvéole, il est repris par le flux d'aspiration provenant de la chambre d'extraction 14.When the extraction device is at rest, the flap 16 is in the lower position, that is to say is brought by the jack until its lower face comes into contact with the honeycomb matrix 3, as shown in FIG. 4. In this position, the shutter closes the lower part of the channel 15 and, through the openings 22 formed through it, creates a suction flow which, as shown by the arrow 33 in FIG. 4, circulates in the upper part of the corridor input 18 and has no effect on the objects 1 placed in the cells 4, below the opening 13. In this position, the inclined face 32a of the step 32 ensures the repositioning of the objects 1 contained in the cells and which could be partially lifted by the suction. When the detection barrier B has detected an anomaly in =. one of the rows of cells, this information is stored in a control unit 34 until the corresponding row reaches, by stepwise movement, at the opening 13. Under these conditions, the housing control 34 controls, on the one hand, by the distributor 26 the supply of compressed air to the blowing network, and on the other hand, by a distributor 35 the supply of the actuator 20b in the direction of elevation of its rod 20a. As a result, the channels 28 deliver, in each cell, a jet of pressurized air entering the cell and expelling the contents outside as shown for a tablet 1 in Figure 2. As soon as the tablet is extracted from the cell, it is taken up by the suction flow coming from the extraction chamber 14.
On notera que dans cette position, et comme montré à la figure 2, les faces pentues 23c et 32a, respectivement de la barrette 23 et du redan 32 du volet, forment un couloir qui canalise le flux provenant de l'extérieur en direction de la matrice alvéolée et ceci afin de combiner l'aspiration du flux entrant dans la chambre 14 et la poussée du flux d'entrée pénétrant dans le canal 18 pour déplacer les produits extraits des alvéoles 4. A ce stade, et de façon connue par l'état de la technique, les objets prélevés sont déplacés automatiquement jusqu'au récipient 7 montré à la figure 1.It will be noted that in this position, and as shown in FIG. 2, the sloping faces 23c and 32a, respectively of the bar 23 and of the step 32 of the shutter, form a corridor which channels the flow coming from the outside towards the honeycomb matrix and this in order to combine the suction of the flow entering the chamber 14 and the thrust of the inlet flow entering the channel 18 to move the products extracted from the cells 4. At this stage, and in a manner known by the state of the art, the sampled objects are automatically moved to the container 7 shown in FIG. 1.
En fin de cycle, la commande 34 intervient sur les distributeurs 26 et 35 pour stopper l'émission du jet d'air comprimé et pour ramener le volet 16 dans sa position initiale de fermeture partielle du canal 15. On rappelera ici que, selon la forme, la section, le poids et la disposition des objets dans les alvéoles 4, l'émission de jet d'air comprimé chassant sur les objets des alvéoles les contenant peut être déclenchée avant ou après que le volet 16 ait été amené en position supérieure d'extraction.At the end of the cycle, the command 34 intervenes on the distributors 26 and 35 to stop the emission of the jet of compressed air and to return the flap 16 to its initial position of partial closure of the channel 15. It will be recalled here that, depending on the shape, the section, the weight and the arrangement of the objects in the cells 4, the emission of a jet of compressed air driving out the objects of the cells containing them can be triggered before or after the shutter 16 has been brought into the upper extraction position.
Avantageusement, et pour réduire la vitesse de circulation des objets prélevés dans le circuit d'extraction 6, ce circuit est doté d'un canal de perte de charge 36 qui est obturé par une électrovanne 37 reliée par un circuit 38 à la commande 34. Dans la forme d'exécution représentée, le canal 36 est disposé à l'extrémité de la chambre d'alimentation 14 du coprs 10, mais il peut être disposé en tout autre endroit du circuit d'extraction.Advantageously, and to reduce the speed of circulation of the objects removed in the extraction circuit 6, this circuit is provided with a pressure drop channel 36 which is closed by a solenoid valve 37 connected by a circuit 38 to the control 34. In the embodiment shown, the channel 36 is arranged at the end of the supply chamber 14 of the body 10, but it can be arranged in any other place of the extraction circuit.
Grâce à cela, dès que les objets ont pénétré dans la chambre d'extraction 14, la commande 34 intervient par son circuit 38 sur 1 •électrovanne 37, de manière qu'elle dégage le canal 36. Cela a pour conséquence d'augmenter la section d'entrée du flux d'aspiration et en conséquence de réduire la vitesse du fluide dans le circuit correspondant. De ce fait, les produits sont déplacés avec une moins grande vitesse et ont moins de chance de se fracasser contre les parois, lorsqu'ils sont fragiles, comme c'est le cas pour des comprimés.Thanks to this, as soon as the objects have entered the extraction chamber 14, the control 34 intervenes by its circuit 38 on 1 • solenoid valve 37, so that it releases the channel 36. This has the consequence of increasing the inlet section of the suction flow and consequently reduce the speed of the fluid in the corresponding circuit. As a result, the products are moved with less speed and are less likely to shatter against the walls, when they are fragile, as is the case with tablets.
Suivant une autre caractéristique de l'invention montrée à la figure 4, la face 16a du volet 16, qui est tournée vers l'aval, est séparée par un esapce e de la face 10a du corps 10, en vis à vis de laquelle elle vient lorsque le volet est en position d'obturation. Cet espace a une valeur qui, faible et comprise entre 0,1 et 0,5 mm, est suffisante pour former, à cet endroit, une fente mettant à profil l'aspiration régnant dans le canal 15 pour dégager la surface de la matrice alvéolée 3 de toute poussière, pour que cette surface reçoive dans de bonnes conditions le film 5 d'obturation des alvéoles. Lorsque le dispositif est mis en oeuvre pour vider des alvéoles 4 contenant de la poudre, l'espace e est supprimé, de sorte que les faces 16a et 10a viennent en contact d'étanchéité l'une contre l'autre. Enfin, comme montré en traits mixtes à la figureAccording to another characteristic of the invention shown in FIG. 4, the face 16a of the flap 16, which is turned downstream, is separated by a space from the face 10a of the body 10, opposite which it comes when the shutter is in the closed position. This space has a value which, small and between 0.1 and 0.5 mm, is sufficient to form, at this location, a slot profiling the suction prevailing in the channel 15 to clear the surface of the honeycomb matrix 3 of any dust, so that this surface receives in good conditions the film 5 for closing the cells. When the device is used to empty cells 4 containing powder, the space e is eliminated, so that the faces 16a and 10a come into sealing contact against each other. Finally, as shown in phantom in Figure
2, l'alimentation de la chambre d'extraction 14 par le flux d'aspiration peut être assurée par un raccord radial 40 se substituant au raccord axial montré à la figure 3. Avec cet aménagement, le circuit d'extraction comporte des changements de direction de grands rayons, ce qui réduit les risques de détérioration des produits véhiculés par le fluide.2, the supply of the extraction chamber 14 by the suction flow can be ensured by a radial connection 40 replacing the axial connection shown in FIG. 3. With this arrangement, the extraction circuit includes changes in direction of large rays, which reduces the risks of deterioration of the products conveyed by the fluid.
Le dispositif selon l'invention permet, sous un volume réduit, d'assurer le vidage complet des alvéoles d'une rangée défaillante, et cela quel que soit le contenu des alvéoles. Ce dispositif peut fonctionner avec des cadences élevées, sans pour autant détériorer les objets récupérés qui peuvent aussi être ramenés après triage au poste de distribution. A titre d'exemple, alors qu'un dispositif sans jet d'air comprimé, peut extraire chaque minute 220 plaquettes de 40 mm de large contenant chacune deux rangées de 10 comprimés ayant un diamètre de 10 mm et un poids de 350 Mg, le dispositif selon l'invention permet, avec le même conditionnement, d'atteindre 350 plaquettes par minute. The device according to the invention allows, under a reduced volume, to ensure the complete emptying of the cells of a failing row, and this whatever the content of the cells. This device can operate at high speeds, without damaging the recovered objects which can also be brought back after sorting at the distribution station. For example, while a device without a jet of compressed air, can extract each minute 220 40 mm wide blisters each containing two rows of 10 tablets having a diameter of 10 mm and a weight of 350 Mg, the device according to the invention allows, with the same packaging, to reach 350 wafers per minute.
