Au cours de l'étape de traitement de la bouteille, un fluide précurseur est injecté dans la bouteille et soumis à l'action de micro-ondes de sorte qu'il passe à l'état de plasma et provoque un dépôt sur les parois internes de la bouteille. Il est par exemple connu de réaliser des dépôts à base de carbone amorphe hydrogéné qui constitue un revêtement interne formant barrière, notamment à rencontre des molécules de dioxygène et de dioxyde de carbone, en utilisant de l'acétylène en tant que précurseur ; il est encore connu de réaliser des dépôts à base de silice, en utilisant un composé organo-silicé en tant que précurseur.During the treatment step of the bottle, a precursor fluid is injected into the bottle and subjected to the action of microwaves so that it passes to the state of plasma and causes a deposit on the inner walls from the bottle. It is for example known to produce deposits based on hydrogenated amorphous carbon which constitutes an inner barrier coating, in particular against oxygen and carbon dioxide molecules, using acetylene as a precursor; it is still known to produce silica-based deposits, using an organo-siliceous compound as a precursor.
Après l'étape de traitement, il est nécessaire de nettoyer l'intérieur de la bouteille en vue d'en retirer les résidus de réaction qui se sont déposés sur ses parois internes mais qui ne font pas partie du revêtement interne.After the treatment step, it is necessary to clean the inside of the bottle in order to remove the residues from it. reaction which are deposited on its internal walls but which are not part of the internal coating.
Plus généralement, ce type de machine peut être agencé dans toute installation de traitement de récipients, qu'ils soient en matériau plastique ou pas, lesquels récipients nécessitent d'être débarrassés de résidus qu'ils sont susceptibles de contenir à l'intérieur : ainsi, sans que ce soit limitatif, il peut s'agir d'installations de nettoyage de récipients réutilisés ou de récipients qui ont été stockés entre leur fabrication et leur remplissage.More generally, this type of machine can be arranged in any container treatment plant, whether plastic or not, which containers need to be rid of residues that they may contain inside: , without limitation, it may be facilities for cleaning reused containers or containers that have been stored between their manufacture and filling.
Les machines actuelles réalisent le nettoyage des parois internes de la bouteille en insufflant de l'air, par l'intermédiaire de la buse, suivant un jet dirigé axialement vers la paroi de fond de la bouteille. De plus, l'ouverture de la bouteille est raccordée à un dispositif d'aspiration qui récupère les résidus décollés au moyen de l'insufflation d'air.Current machines perform the cleaning of the inner walls of the bottle by blowing air through the nozzle, in a jet directed axially towards the bottom wall of the bottle. In addition, the opening of the bottle is connected to a suction device which recovers the unstuck residue by means of air blowing.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the following description, identical, similar or similar elements will be designated by the same reference numerals.
Sur la figure 1 , on a représenté une machine 10 de nettoyage par insufflation des parois internes d'un récipient tel qu'une bouteille 12 réalisée conformément aux enseignements de l'invention.In Figure 1, there is shown a machine 10 for cleaning by blowing the inner walls of a container such as a bottle 12 made according to the teachings of the invention.
La machine 10 est prévue notamment pour être agencée dans une installation de traitement de bouteilles 12, en vue d'en extraire des résidus qui polluent l'intérieur des bouteilles 12. De préférence, lorsque l'installation de traitement de bouteilles 12 est conçue pour réaliser un revêtement barrière (à base de carbone ou de silice, par exemple), la machine 10 est disposée immédiatement en aval de l'unité de traitement permettant de réaliser ledit revêtement barrière afin que les résidus de réaction soient éliminés au plus vite. La machine peut encore être agencée en amont d'une installation de remplissage.The machine 10 is provided in particular to be arranged in a bottle treatment installation 12, in order to extract residues which pollute the inside of the bottles 12. Preferably, when the bottle treatment installation 12 is designed to to produce a barrier coating (based on carbon or silica, for example), the machine 10 is disposed immediately downstream of the processing unit for producing said barrier coating so that the reaction residues are removed as quickly as possible. The machine can still be arranged upstream of a filling installation.
La machine 10 comporte plusieurs postes 14 de nettoyage qui sont montés à rotation autour d'un axe principal A1 vertical et qui sont répartis circonférentiellement autour de l'axe principal A1.The machine 10 comprises a plurality of cleaning stations 14 which are rotatably mounted about a vertical main axis A1 and which are distributed circumferentially about the main axis A1.
Selon une variante de réalisation (non représentée), l'axe principal A1 pourrait être incliné par rapport à la direction verticale. Pour simplifier la représentation, un seul poste 14 de nettoyage est représenté sur la figure 1.According to an alternative embodiment (not shown), the main axis A1 could be inclined relative to the vertical direction. To simplify the representation, only one cleaning station 14 is shown in FIG.
Chaque poste 14 de nettoyage est prévu pour être raccordé à une source 16 de gaz sous pression, tel que de l'air comprimé. La source 16 d'air comprimé est commune à tous les postes 14 de nettoyage.Each cleaning station 14 is intended to be connected to a source 16 of gas under pressure, such as compressed air. The source 16 of compressed air is common to all cleaning stations 14.
La machine 10 comporte un socle 18 fixe sur lequel une plate-forme 20 est montée à rotation autour de l'axe principal A1.The machine 10 comprises a fixed base 18 on which a platform 20 is rotatably mounted about the main axis A1.
La plate-forme 20 est entraînée en rotation autour de son axe A1 , par exemple au moyen d'un moteur électrique (non représenté).The platform 20 is rotated about its axis A1, for example by means of an electric motor (not shown).
Chaque poste 14 de nettoyage comporte un châssis 22 qui est fixé sur la face transversale supérieure 24 de la plate-forme 20. Selon le mode de réalisation représenté, la machine 10 comporte une poutre 26 fixe qui s'étend transversalement au- dessus de la plate-forme 20 et qui supporte un distributeur 28 de gaz, typiquement de l'air comprimé, raccordé à la source 16.Each cleaning station 14 comprises a frame 22 which is fixed on the upper transverse face 24 of the platform 20. According to the embodiment shown, the machine 10 comprises a fixed beam 26 which extends transversely above the platform 20 and which supports a gas distributor 28, typically compressed air, connected to the source 16.
Le distributeur 28 comporte un arbre 30 central tubulaire qui est fixé sur la poutre 26 et qui délimite une conduite principale 31 , axiale, raccordée à la source 16, et un moyeu 32 de raccordement qui est monté à rotation sur l'arbre 30 et qui comporte des canaux radiaux 33, 35 susceptibles de communiquer avec la conduite principale 31. Le moyeu 32 comporte, à son extrémité axiale inférieure, un disque 34 de liaison qui est fixé sur les châssis 22 de manière que le moyeu 32 soit lié en rotation avec les postes 14 de nettoyage.The distributor 28 comprises a tubular central shaft 30 which is fixed on the beam 26 and which delimits a main pipe 31, axial, connected to the source 16, and a connection hub 32 which is rotatably mounted on the shaft 30 and which comprises radial channels 33, 35 likely to communicate with the main pipe 31. The hub 32 has, at its lower axial end, a connecting disc 34 which is fixed on the frames 22 so that the hub 32 is rotatably connected with cleaning stations 14.
Le distributeur 28 sera décrit de manière plus détaillée par la suite.Dispenser 28 will be described in more detail later.
Chaque poste 14 de nettoyage est équipé d'un tube 36 d'insufflation qui s'étend suivant un axe A2 sensiblement vertical, qui est raccordé au distributeur 28, et qui est pourvu, à son extrémité axiale supérieure, d'une buse 38 globalement cylindrique prévue pour insuffler l'air comprimé vers les parois internes du récipient 12.Each cleaning station 14 is equipped with an insufflation tube 36 which extends along a substantially vertical axis A2, which is connected to the distributor 28, and which is provided, at its upper axial end, with a nozzle 38 generally. cylindrical tube for injecting compressed air towards the inner walls of the container 12.
Selon une variante de réalisation (non représentée), l'axe A2 pourrait être incliné par rapport à l'axe principal A1 et/ou par rapport à la direction verticale.According to an alternative embodiment (not shown), the axis A2 could be inclined relative to the main axis A1 and / or relative to the vertical direction.
Le tube 36 d'insufflation est emmanché dans un boîtier 40 mobile de raccordement.The insufflation tube 36 is fitted into a mobile connection box 40.
Le boîtier 40 mobile est guidé en coulissement vertical par deux montants 42, 44 verticaux formant une portion du châssis 22.The mobile housing 40 is guided in vertical sliding by two uprights 42, 44 forming a vertical portion of the frame 22.
Selon le mode de réalisation représenté, le boîtier 40 mobile est équipé d'un chariot 46, tel un chariot à billes qui coulisse sur un rail 48 vertical porté par l'un des montants 44.According to the embodiment shown, the mobile housing 40 is equipped with a carriage 46, such as a slide carriage which slides on a vertical rail 48 carried by one of the uprights 44.
Le boîtier 40 mobile est commandé en coulissement axial par un mécanisme 50 comprenant un galet 52 qui est porté par le boîtier 40 et qui se déplace sur une piste de roulement 54, ou came, associée au cours d'un cycle de nettoyage.The mobile housing 40 is controlled in axial sliding by a mechanism 50 comprising a roller 52 which is carried by the housing 40 and which moves on a running track 54, or cam, associated during a cleaning cycle.
La piste de roulement 54 est fixée sur le socle 18. Elle comporte un tronçon 56 d'altitude maximale qui détermine une position axiale haute du boîtier 40, donc du tube 36 d'insufflation, et deux rampes 58, 60 qui commandent la montée du tube 36 d'insufflation depuis sa position axiale basse jusqu'à sa position axiale haute, et la descente du tube 36 d'insufflation depuis sa position axiale haute jusqu'à sa position axiale basse. La position basse du tube 36 d'insufflation peut être déterminée par un moyen de butée axiale (non représenté).The running track 54 is fixed on the base 18. It comprises a section 56 of maximum altitude which determines a high axial position of the housing 40, therefore of the insufflation tube 36, and two ramps 58, 60 which control the rise of the insufflation tube 36 from its low axial position to its high axial position, and the descent of the insufflation tube 36 from its high axial position to its low axial position. The low position of insufflation tube 36 can be determined by axial stop means (not shown).
Le cycle de nettoyage mis en œuvre par un poste 14 de nettoyage de la machine 10, au cours d'une rotation complète de la plate-forme 20, comporte ainsi une phase de montée Pm correspondant à la course montante du tube 36 d'insufflation, depuis sa position basse jusqu'à sa position haute, et une phase de descente Pd correspondant à la course descendante du tube 36 d'insufflation, depuis sa position haute jusqu'à sa position basse. Au cours de la phase de montée Pm, la buse 38 pénètre dans la bouteille 12.The cleaning cycle implemented by a cleaning station 14 of the machine 10, during a complete rotation of the platform 20, thus comprises a rise phase Pm corresponding to the rising stroke of the insufflation tube 36 from its low position to its high position, and a descent phase Pd corresponding to the downward stroke of the insufflation tube 36, from its high position to its low position. During the rise phase Pm, the nozzle 38 enters the bottle 12.
La position haute du tube 36 d'insufflation est représentée en trait pointillé sur les figures 1 et 3, et la position basse du tube 36 d'insufflation est représentée sur la figure 2.The upper position of the insufflation tube 36 is shown in dotted line in FIGS. 1 and 3, and the lower position of the insufflation tube 36 is shown in FIG.
Le châssis 22 est équipé de moyens de support 62 qui maintiennent la bouteille 12 globalement verticalement de manière que son ouverture 13 soit agencée vers le bas sur l'axe A2 du tube 36 d'insufflation dans une position dite de nettoyage. Comme illustré, les moyens de support 62 peuvent comprendre une pince pivotante qui est prévue pour saisir la bouteille 12 par son col, la bouteille 12 étant positionnée avec son ouverture 13 vers le haut, tel que représenté sur la figure 2, puis pour faire basculer la bouteille 12 autour d'un axe A3 transversal de sorte qu'elle vienne occuper sa position de nettoyage, telle que représentée sur les figures 1 , 3, et 4.The frame 22 is equipped with support means 62 which hold the bottle 12 generally vertically so that its opening 13 is arranged downwardly on the axis A2 of the insufflation tube 36 in a so-called cleaning position. As illustrated, the support means 62 may comprise a pivoting clamp which is provided to grip the bottle 12 by its neck, the bottle 12 being positioned with its opening 13 upwards, as shown in FIG. 2, then to tilt the bottle 12 about a transverse axis A3 so that it comes to occupy its cleaning position, as shown in Figures 1, 3, and 4.
La structure de la buse 38 est représentée de manière détaillée sur les figures 3 et 4, où le tube 36 d'insufflation est représenté, en trait fort, dans une position axiale intermédiaire entre sa position haute et sa position basse.The structure of the nozzle 38 is shown in detail in FIGS. 3 and 4, in which the insufflation tube 36 is shown, in solid lines, in an intermediate axial position between its high position and its low position.
La buse 38 comporte une fente annulaire 64 périphérique qui est apte à former un jet périphérique f2 d'air comprimé de forme globalement tronconique dirigé vers les parois internes 66 latérales de la bouteille 12 et vers le bas. Le jet périphérique f2 est matérialisé sur la figure 4 par des flèches.The nozzle 38 has a peripheral annular slot 64 which is capable of forming a peripheral jet f2 of compressed air of generally frustoconical shape directed towards the inner side walls 66 of the bottle 12 and downwards. The peripheral jet f2 is shown in FIG. 4 by arrows.
Avantageusement, le tube 36 d'insufflation comporte un tube externe 68 et un tube interne 70 coaxiaux qui délimitent entre eux un conduit périphérique 72. Le conduit périphérique 72 débouche à l'extérieur par la fente annulaire 64 de la buse 38.Advantageously, the insufflation tube 36 comprises an outer tube 68 and a coaxial internal tube 70 which delimit between them a peripheral duct 72. The peripheral duct 72 opens outwards through the annular slot 64 of the nozzle 38.
Le tube interne 70 délimite un conduit central 74 qui débouche à l'extérieur par un orifice central 76 situé à l'extrémité axiale supérieure de la buse 38. L'orifice central 76, qui a un profil tronconique, en section axiale, est prévu pour produire un jet central f1 d'air comprimé dirigé vers la paroi interne 75 de fond en vis-à-vis de la bouteille 12. Le jet central f1 est matérialisé sur la figure 3 par des flèches.The inner tube 70 delimits a central duct 74 which opens out through a central orifice 76 located at the upper axial end of the nozzle 38. The central orifice 76, which has a frustoconical profile, in axial section, is provided to produce a central jet f1 of compressed air directed towards the inner wall 75 of the bottom vis-à-vis the bottle 12. The central jet f1 is shown in Figure 3 by arrows.
Selon le mode de réalisation représenté, la buse 38 comporte un bouchon 78 qui obture partiellement l'extrémité axiale supérieure du tube 36 d'insufflation. Le bouchon 78 a une forme de révolution autour de l'axeAccording to the embodiment shown, the nozzle 38 comprises a plug 78 which partially closes the upper axial end of the insufflation tube 36. The plug 78 has a shape of revolution around the axis
A2 et un profil, en coupe axiale, globalement en forme de T.A2 and a profile, in axial section, generally T-shaped.
Le bouchon 78 comporte un tronçon tubulaire 80 inférieur qui est pourvu, à son extrémité axiale supérieure, d'une tête 82 de diamètre externe supérieur au diamètre externe du tronçon tubulaire 80 et sensiblement égal au diamètre externe de l'extrémité supérieure du tube externe 68.The plug 78 has a lower tubular section 80 which is provided, at its upper axial end, with a head 82 of outside diameter greater than the outside diameter of the tubular section 80 and substantially equal to the outside diameter of the upper end of the outer tube 68 .
Le tronçon tubulaire 80 est vissé dans le tronçon d'extrémité supérieure du tube interne 70.The tubular section 80 is screwed into the upper end section of the inner tube 70.
L'orifice central 76 est aménagé dans la face transversale supérieure 84 de la tête 82.The central orifice 76 is arranged in the upper transverse face 84 of the head 82.
Le tronçon tubulaire 80 délimite un conduit 85 d'extrémité qui raccorde le conduit central 74 à l'orifice central 76.The tubular section 80 defines an end duct 85 which connects the central duct 74 to the central orifice 76.
La surface annulaire inférieure 86 de la tête 82 a une forme tronconique s'évasant vers le bas. Le rebord 88 de l'extrémité supérieure du tube externe 68 a une forme tronconique complémentaire de la surface annulaire inférieure 86 de la tête 82, de manière que l'espace axial entre le rebord 88 et la surface annulaire inférieure 86 délimitent une fente annulaire 64 aux parois inclinées par rapport à l'axe A2 du tube 36 d'insufflation.The lower annular surface 86 of the head 82 has a frustoconical shape flaring downwards. The rim 88 of the upper end of the outer tube 68 has a frustoconical shape complementary to the lower annular surface 86 of the head 82, so that the axial space between the rim 88 and the lower annular surface 86 delimits an annular slot 64 the walls inclined relative to the axis A2 of the insufflation tube 36.
Le rebord 88 et la surface annulaire inférieure 86 de la tête 82 permettent ainsi de guider le flux d'air comprimé pour former un jet périphérique f2 de forme globalement tronconique. Avantageusement, le conduit périphérique 72 et le conduit central 74 sont raccordés indépendamment au distributeur 28 par l'intermédiaire de deux conduites flexibles 90, 92 correspondantes. Chaque conduite flexible 90, 92 est connectée, suivant le sens du flux d'air comprimé, en amont au moyeu 32 de raccordement et en aval au boîtier 40 mobile.The rim 88 and the lower annular surface 86 of the head 82 thus guide the flow of compressed air to form a peripheral jet f2 of generally frustoconical shape. Advantageously, the peripheral duct 72 and the central duct 74 are connected independently to the distributor 28 by means of two corresponding flexible pipes 90, 92. Each flexible pipe 90, 92 is connected, in the direction of the flow of compressed air, upstream to the connection hub 32 and downstream to the mobile housing 40.
Selon une caractéristique avantageuse de la machine, le distributeur 28 est prévu pour alimenter en air comprimé uniquement le conduit central 74, pendant au moins une partie de la phase de montée Pm, et uniquement le conduit périphériqueAccording to an advantageous characteristic of the machine, the distributor 28 is provided for supplying compressed air only to the central duct 74, during at least part of the rise phase Pm, and only the peripheral duct
72, pendant au moins une partie de la phase de descente Pd.72 during at least part of the descent phase Pd.
A cet effet, le moyeu 32 de raccordement comporte une piste supérieure 94 de raccordement constituée par une première série de canaux radiaux 33 qui sont agencés dans un même plan transversal et qui sont raccordés chacun au conduit périphériqueFor this purpose, the connection hub 32 comprises an upper connection track 94 constituted by a first series of radial channels 33 which are arranged in the same transverse plane and which are each connected to the peripheral duct.
72 d'un poste 14 de nettoyage déterminé, et une piste inférieure72 of a determined cleaning station 14, and a lower track
96 de raccordement constituée par une seconde série de canaux radiaux 35 qui sont agencés globalement dans un même plan transversal et qui sont raccordés chacun au conduit central 74 d'un poste 14 de nettoyage déterminé.96 connection constituted by a second series of radial channels 35 which are arranged generally in the same transverse plane and which are each connected to the central duct 74 of a specific cleaning station 14.
La piste supérieure 94 de raccordement est représentée en coupe transversale sur la figure 7 et la piste inférieure 96 de raccordement est représentée en coupe transversale sur la figure 6.The upper connection track 94 is shown in cross section in FIG. 7 and the lower connection track 96 is shown in cross section in FIG.
Chaque canal radial 33, 35 comporte, à son extrémité externe, un orifice externe 98 qui est raccordé à une conduite flexible 90, 92 associée et, à son extrémité interne, un orifice interne 100 qui débouche en regard de la paroi axiale de la conduite principale 31 ménagée dans l'arbre 30.Each radial channel 33, 35 has, at its outer end, an external orifice 98 which is connected to a flexible pipe 90, 92 associated and, at its inner end, an inner orifice 100 which opens opposite the axial wall of the pipe main 31 formed in the shaft 30.
La paroi axiale 102 de la conduite principale 31 comporte, à la hauteur axiale de la piste supérieure 94, une fenêtre 104 supérieure de distribution qui est prévue pour faire communiquer plusieurs canaux radiaux 33 de la piste supérieure 94 avec la conduite principale 31 , pendant un secteur angulaire du cycle de rotation du moyeu 32.The axial wall 102 of the main pipe 31 comprises, at the axial height of the upper track 94, an upper distribution window 104 which is provided for communicating several radial channels 33 of the upper track 94 with the main pipe 31, during an angular sector of the rotation cycle of the hub 32.
De manière similaire, la paroi axiale 102 de la conduite principale 31 comporte, à la hauteur axiale de la piste inférieure 96, une fenêtre 106 inférieure de distribution qui est prévue pour faire communiquer plusieurs canaux radiaux 35 de la piste inférieure 96 avec la conduite principale 31 , pendant un secteur angulaire du cycle de rotation du moyeu 32.Similarly, the axial wall 102 of the main pipe 31 comprises, at the axial height of the lower track 96, a lower distribution window 106 which is provided to communicate several radial channels 35 of the lower track 96 with the main pipe. 31, during an angular sector of the rotation cycle of the hub 32.
Avantageusement, chaque fenêtre 104, 106 de distribution s'étend sur un secteur angulaire de valeur supérieure à l'écart angulaire entre deux orifices externes 98 consécutifs de manière à alimenter simultanément au moins deux canaux radiaux 33, 35 appartenant à la même piste 94, 96, ce qui permet de réaliser le nettoyage simultanément dans au moins deux postes 14 de nettoyage.Advantageously, each distribution window 104, 106 extends over an angular sector of greater value than the angular difference between two consecutive external orifices 98 so as to simultaneously feed at least two radial channels 33, 35 belonging to the same track 94, 96, which makes it possible to carry out the cleaning simultaneously in at least two cleaning stations 14.
De préférence, les canaux radiaux 33, 35 sont répartis circonférentiellement de manière régulière.Preferably, the radial channels 33, 35 are distributed circumferentially in a regular manner.
On décrit maintenant le fonctionnement de la machine 10 au regard du cycle de nettoyage mis en œuvre par un poste 14 de nettoyage.The operation of the machine 10 is now described with regard to the cleaning cycle implemented by a cleaning station 14.
Pendant le fonctionnement de la machine 10, la source 16 envoie de l'air comprimé dans le distributeur 28 et la plate-forme 20 est entraînée en rotation autour de son axe A1 , dans le sens horaire R en considérant la figure 1. Le tube 36 d'insufflation et le boîtier 40 mobile occupant leur position basse, la bouteille 12 est saisie par la pince associée aux moyens de support 62, tel que représenté sur la figure 2.During the operation of the machine 10, the source 16 sends compressed air into the distributor 28 and the platform 20 is rotated about its axis A1, in the clockwise direction R taking into consideration FIG. 36 and the mobile housing 40 occupying their low position, the bottle 12 is gripped by the clamp associated with the support means 62, as shown in Figure 2.
La pince appartenant aux moyens de support 62 est ensuite commandée en pivotement autour de son axe A3 jusqu'à ce qu'elle vienne occuper la position de nettoyage.The clamp belonging to the support means 62 is then pivotally controlled about its axis A3 until it comes to occupy the cleaning position.
Pendant le pivotement de la pince associée aux moyens de support 62, ou à la fin de ce pivotement, le galet 52 du poste 14 de nettoyage, qui tourne autour de l'axe principal A1 , vient en contact avec la rampe 60 de montée de la piste de roulement 54 et coopère avec cette rampe 60 ce qui provoque le coulissement du tube 36 d'insufflation depuis sa position basse vers sa position haute. Pendant l'essentiel de la phase de montée Pm, qui est illustrée par la figure 3, l'orifice interne 100 du canal radial 35 associé au conduit central 74 du tube 36 d'insufflation est en regard de la fenêtre 106 inférieure de distribution, alors que l'orifice interne 100 du canal radial 33 associé au conduit périphérique 72 est en regard de la paroi axiale 102 de l'arbre 30. Par conséquent, seul l'orifice central 76 est alimenté en air comprimé qui circule suivant la flèche F1.During the pivoting of the clamp associated with the support means 62, or at the end of this pivoting, the roller 52 of the cleaning station 14, which rotates about the main axis A1, comes into operation. contact with the ramp 60 of the runway 54 and cooperates with this ramp 60 which causes the sliding of the insufflation tube 36 from its lower position to its upper position. During most of the rising phase Pm, which is illustrated in FIG. 3, the internal orifice 100 of the radial channel 35 associated with the central duct 74 of the insufflation tube 36 is facing the lower distribution window 106, whereas the internal orifice 100 of the radial channel 33 associated with the peripheral duct 72 is facing the axial wall 102 of the shaft 30. Therefore, only the central orifice 76 is supplied with compressed air which flows along the arrow F1 .
L'orifice central 76 de la buse 38 produit donc un jet central f1 vers la paroi interne 75 de fond qui tend à décrocher les résidus présents dans la bouteille 12, en particulier sur la paroi interne 75 de fond.The central orifice 76 of the nozzle 38 thus produces a central jet f1 towards the inner wall 75 of bottom which tends to unhook the residues present in the bottle 12, in particular on the inner wall 75 of the bottom.
De manière classique, le poste 14 de nettoyage peut comporter des moyens d'aspiration (non représentés) raccordés sur l'ouverture 13 de la bouteille 12 pour aspirer les résidus décrochés par le jet d'air comprimé.Typically, the cleaning station 14 may comprise suction means (not shown) connected to the opening 13 of the bottle 12 to suck the residues unhooked by the jet of compressed air.
Vers la fin de la phase de montée Pm, l'orifice interne 100 du canal radial 33 associé au conduit périphérique 72 du tube 36 d'insufflation vient en regard de la fenêtre 104 supérieure de distribution, de sorte que le conduit périphérique 72 est alimenté en air comprimé.Towards the end of the rise phase Pm, the internal orifice 100 of the radial channel 33 associated with the peripheral duct 72 of the insufflation tube 36 comes opposite the upper distribution window 104, so that the peripheral duct 72 is fed with in compressed air.
La fente annulaire 64 produit alors le jet périphérique f2 qui tend à décrocher les résidus présents sur les parois internes de la bouteille 12, en particulier sur les parois internes 66 latérales. Le tube 36 d'insufflation parvient à sa position haute, déterminée par l'arrivée du galet 52 sur le tronçon 56 d'altitude maximale de la piste de roulement 54, tel que représenté sur la figure 1. Le galet 52 parcourt ensuite la rampe 58 de descente ce qui provoque le couiissement du tube 36 d'insufflation vers le bas, c'est-à-dire la phase de descente Pd.The annular slot 64 then produces the peripheral jet f2 which tends to unhook the residues present on the inner walls of the bottle 12, in particular on the internal side walls 66. The insufflation tube 36 reaches its upper position, determined by the arrival of the roller 52 on the section 56 of maximum altitude of the raceway 54, as shown in FIG. The roller 52 then travels down the ramp 58 which causes the squash tube 36 blowing down, that is to say, the descent phase Pd.
Au début de la phase de descente Pd1 l'orifice interne 100 du canal radial 35 associé au conduit central 74 dépasse angulairement la fenêtre 106 inférieure de distribution, de sorte que le conduit central 74 n'est plus alimenté en air comprimé.At the beginning of the descent phase Pd 1 the internal orifice 100 of the radial channel 35 associated with the central duct 74 angularly exceeds the lower distribution window 106, so that the central duct 74 is no longer supplied with compressed air.
Pendant le reste de la phase de descente Pd, seul le conduit périphérique 72 est alimenté en air comprimé qui circule suivant la flèche F2.During the remainder of the descent phase Pd, only the peripheral duct 72 is supplied with compressed air which circulates along the arrow F2.
On constate que la forme particulière du jet périphérique f2 d'air comprimé produit par la fente annulaire 64, à savoir sa forme globalement tronconique, crée une dépression importante dans la partie haute de la bouteille 12, c'est-à-dire au-dessus du jet périphérique f2.It is found that the particular shape of the peripheral jet f2 of compressed air produced by the annular slot 64, namely its generally frustoconical shape, creates a significant depression in the upper part of the bottle 12, that is to say above the peripheral jet f2.
Cette dépression, associée à la position ouverture de la bouteille vers le bas, permet d'éliminer de manière efficace les derniers résidus présents dans la bouteille 12.This depression, associated with the opening position of the bottle downwards, effectively eliminates the last residues present in the bottle 12.
A la fin de la phase de descente Pd, l'orifice interne 100 du canal radial 35 associé au conduit périphérique 72 dépasse angulairement la fenêtre 104 supérieure de distribution, de sorte que le conduit périphérique 72 n'est plus alimenté en air comprimé.At the end of the descent phase Pd, the internal orifice 100 of the radial channel 35 associated with the peripheral duct 72 angularly exceeds the upper distribution window 104, so that the peripheral duct 72 is no longer supplied with compressed air.
La bouteille 12, débarrassée de ses résidus, peut alors être retirée du poste 14 de nettoyage.The bottle 12, free of residues, can then be removed from the cleaning station 14.
Selon le mode de réalisation décrit précédemment, le conduit central 74 et le conduit périphérique 72 sont alimentés simultanément en air comprimé au voisinage de la position haute du tube 36 d'insufflation. Selon une variante de réalisation (non représentée), les fenêtres 104, 106 de distribution, ou les orifices internes 100, peuvent être agencés de manière que l'alimentation du conduit périphérique 72 commence après la fin de l'alimentation du conduit central 74. According to the embodiment described above, the central duct 74 and the peripheral duct 72 are simultaneously supplied with compressed air in the vicinity of the upper position of the insufflation tube 36. According to an alternative embodiment (not shown), the windows 104, 106 of distribution, or the internal orifices 100, can be arranged so that the supply of the peripheral duct 72 begins after the end of the supply of the central duct 74.
