Abstract

The invention relates to a conveyor device comprising rectilinear segments and at least one curved segment and means for adjusting the distance between the guide rails (5) which serve as sub-neck guides. The aforementioned rails (5) are formed by a section which is made from thermoplastic material and which is fixed to a support (11), whereby said support (11) can move in relation to the frame (10) of the conveyor device by means of actuating cylinders (16). According to the invention, each rail (5) extends integrally on either side of the joint between the curved segment and the adjacent rectilinear segment. Moreover, each support (11) comprises clamp and slide means which are used to fix the corresponding rail (5) partially, such as to confer thereon a certain degree of longitudinal freedom in order to absorb elastically variations in length caused by a change in the radius of curvature when the distance between the rails (5) is modified. Each support (11) is integral with a base plate (12) comprising a crescent-shaped arched prong having a cross-section which varies between the ends thereof such that it can deform elastically in quasi-uniformly along the entire length thereof under the effect of the actuating cylinders (16).

Description

DISPOSITIF CONVOYEUR SUSCEPTIBLE D' ACCEUILLIR DES BOUTEILLES DE DIMENSIONS DIFFERENTESCONVEYOR DEVICE CAPABLE OF RECEIVING BOTTLES OF DIFFERENT DIMENSIONS
La présente invention concerne un dispositif convoyeur utilisable pour le transport d'articles du genre bouteilles, flacons ou autres.The present invention relates to a conveyor device that can be used for transporting articles of the bottle, flask or other type.
Ce dispositif convoyeur comporte des tronçons rectilignes et des tronçons courbes, et les articles se déplacent d'une façon continue, suspendus dans un couloir formé par des rails parallèles.This conveyor device comprises rectilinear sections and curved sections, and the articles move in a continuous manner, suspended in a corridor formed by parallel rails.
Les formes et dimensions des articles du genre bouteilles, flacons ou autres étant d'une grande variété, il est nécessaire de pouvoir disposer d'un matériel de convoyage très souple, capable de s'adapter rapidement à un changement de formats.The shapes and dimensions of the articles of the bottle, vial or other type being of a great variety, it is necessary to be able to have a very flexible conveying equipment, able to adapt quickly to a change of formats.
Le document FR2793228 décrit, tout comme le document FR2806395, un dispositif convoyeur pour des articles du genre bouteilles ; ce dispositif comporte des moyens qui permettent de régler l'écartement entre les deux rails de guidage, lesquels rails sont communément appelés « guides sous col ». Ces guides sous col supportent chaque bouteille au niveau de son goulot, lequel goulot comporte à cet effet une collerette qui se situe en fait sous le col de ladite bouteille.The document FR2793228 describes, like the document FR2806395, a conveyor device for articles of the bottle type; this device comprises means for adjusting the spacing between the two guide rails, which rails are commonly called "guides under collar". These guides under collar support each bottle at its neck, which neck has for this purpose a collar which is actually under the neck of said bottle.
Ces bouteilles sont mises en mouvement, comme décrit dans les documents précités, par un flux d'air qui agit sur la surface du goulot, et en particulier sur la partie qui se situe au-dessus de la collerette de la bouteille, c'est-à-dire sur la surface qui se situe également au-dessus des rails de guidage ou guides sous col.These bottles are set in motion, as described in the aforementioned documents, by a flow of air which acts on the surface of the neck, and in particular on the part which is located above the collar of the bottle, it is ie on the surface which is also above the guide rails or under-collar guides.
L'amplitude du réglage de ces rails, ou guides sous col, reste cependant limitée, notamment pour les convoyeurs courbes, en raison d'une part, des variations de longueur des périmètres extrados et intrados du couloir lors de l'écartement desdits rails et, d'autre part, des difficultés rencontrées pour obtenir une variation du rayon de courbure tout en conservant des tolérances acceptables au niveau de la régularité de l'écartement desdits rails ou guides sous col.The amplitude of the adjustment of these rails, or guides under collar, remains however limited, in particular for the curved conveyors, because on the one hand, variations of length of the extrados and intrados perimeters of the corridor during the spacing of said rails and on the other hand, difficulties encountered in obtaining a variation of the radius of curvature while maintaining acceptable tolerances in the regularity of the spacing of said rails or guides under the neck.
De plus, les variations de longueur des parties courbes du couloir introduisent des ruptures de continuité dans le guidage des bouteilles au niveau du raccordement entre lesdites parties courbes et les parties rectilignes du convoyeur. Ces ruptures de continuité du guidage sont particulièrement nuisibles en raison de leur position car elles se situent en début et en fin de courbe et en raison de leurs dimensions car, selon le cas, elles peuvent atteindre, voire dépasser, 10 à 15 mm. De ce fait, les ruptures de continuité dans le guidage des articles, et en particulier des bouteilles, peuvent provoquer des ralentissements, voire des blocages, dans la ligne de convoyage avec toutes les conséquences que cela peut engendrer sur la productivité, le rendement.In addition, the variations in length of the curved portions of the passageway introduce discontinuities in the guiding of the bottles at the connection between said curved portions and the rectilinear parts of the conveyor. These discontinuities of continuity of the guide are particularly harmful because of their position because they are at the beginning and end of the curve and because of their size because, depending on the case, they can reach or exceed 10 to 15 mm. As a result, discontinuities in the guidance of articles, and in particular bottles, can cause slowdowns or even blockages in the conveyor line with all the consequences that this can have on productivity, yield.
La présente invention propose un dispositif convoyeur aménagé pour remédier aux inconvénients des dispositifs précités. Le dispositif convoyeur selon l'invention permet d'accueillir des familles d'articles du genre bouteilles, flacons et autres dont les dimensions sont différentes et il permet surtout d'améliorer le guidage de ces articles, grâce à une véritable continuité de leur guidage et grâce aussi à une plus grande régularité de la largeur du couloir de guidage, notamment dans les parties courbes.The present invention provides a conveyor device arranged to overcome the disadvantages of the aforementioned devices. The conveyor device according to the invention makes it possible to accommodate families of articles of the bottle, vial and other type whose dimensions are different and it makes it possible especially to improve the guiding of these articles, thanks to a real continuity of their guidance and thanks also to a greater regularity of the width of the guide corridor, especially in the curved parts.
Le dispositif convoyeur selon l'invention, comporte : - des tronçons rectilignes et au moins un tronçon courbe disposé entre deux tronçons rectilignes et, - des moyens de réglage de Pécartement des rails de guidage, lesquels rails sont constitués d'un profilé en matériau thermoplastique, faisant office dé guide sous col, qui est fixé sur un support, lequel support est lui-même solidaire d'une semelle qui est mobile par rapport au bâti du dispositif convoyeur sous l'effet de moyens du genre vérins interposés entre les deux, lequel dispositif convoyeur comporte, au niveau d'une portion de convoyeur comprenant un tronçon courbe et des tronçons rectilignes adjacents à ce dernier, d'une part, au moins un rail constitué d'un profilé en matériau thermoplastique faisant office de guide sous col qui s'étend d'un seul tenant de part et d'autre de la jonction entre ledit tronçon courbe et chaque tronçon rectiligne adjacent, et, d'autre part, un support pour ledit rail, disposé sur chacun desdits tronçons, courbe et rectilignes, chaque support comportant des moyens pour réaliser une fixation partielle dudit rail, du genre bride et glissière, laquelle fixation confère audit rail un certain degré de liberté en translation longitudinale par rapport auxdits supports et lui permet d'absorber élastiquement les variations de longueur provoquées par le changement de son rayon de courbure lorsque Pécartement entre lesdits rails est modifié en raison d'un changement de type d'articles, bouteilles, flacons ou autres.The conveyor device according to the invention comprises: rectilinear sections and at least one curved section disposed between two rectilinear sections; and means for adjusting the spacing of the guide rails, which rails consist of a section made of thermoplastic material. , acting as a guide under the neck, which is fixed on a support, which support is itself secured to a sole which is movable relative to the frame of the conveyor device under the effect of the means of the kind jacks interposed between the two, which conveyor device comprises, at a conveyor portion comprising a curved section and rectilinear sections adjacent to the latter, on the one hand, at least one rail consisting of a section of thermoplastic material acting as an under-collar guide which extends in one piece on either side of the junction between said curved section and each adjacent rectilinear section, and, on the other hand, a support for said rail, say placed on each of said sections, curved and rectilinear, each support comprising means for partially fixing said rail, of the flange and slide type, which attachment gives said rail a certain degree of freedom in longitudinal translation relative to said supports and allows it to elastically absorbing length variations caused by changing its radius of curvature when the spacing between said rails is changed due to a change in the type of articles, bottles, flasks or the like.
Selon une autre disposition de l'invention, des moyens de fixation et de blocage du rail sont interposés entre ce dernier et son support, à chaque extrémité de la partie extrados de la portion courbe du convoyeur, pour éviter tout allongement dudit rail sur cette partie extrados. Toujours selon l'invention, les rails comportent, dans la zone où ils sont susceptibles de s'allonger, des réductions de sections qui se présentent sous la forme d'orifices ou d'entailles transversales, afin de faciliter l'allongement desdits rails et de cantonner cet allongement dans une zone déterminée par lesdites réductions de sections. Selon l'invention, la semelle disposée dans la portion courbe du convoyeur, est constituée d'une lame cintrée, de forme lunulaire, dont la variation de section entre ses extrémités est telle que cette lame peut se déformer élastiquement d'une façon quasi uniforme sur toute sa longueur sous l'effet de vérins, ce qui permet l'obtention d'un rayon de courbure quasi identique en tous points du rail.According to another embodiment of the invention, means for fixing and locking the rail are interposed between the latter and its support, at each end of the extrados portion of the curved portion of the conveyor, to prevent any extension of said rail on this part. upper surface. Still according to the invention, the rails comprise, in the zone where they are likely to lengthen, reductions of sections which are in the form of orifices or transverse cuts, in order to facilitate the elongation of said rails and to limit this elongation in a zone determined by said section reductions. According to the invention, the soleplate disposed in the curved portion of the conveyor, consists of a curved blade, of lunar shape, whose section variation between its ends is such that this blade can deform elastically in an almost uniform manner along its length under the effect of jacks, which allows to obtain a radius of curvature almost identical in all points of the rail.
Selon une autre disposition de l'invention, les vérins de manœuvre de chaque semelle lunulaire du tronçon courbe sont répartis sur la longueur de ladite semelle, l'un desdits vérins étant disposé à mi-longueur de ladite semelle, pour établir et stabiliser sa position par rapport au bâti du dispositif convoyeur, les autres vérins étant disposés latéralement, un à chaque extrémité de ladite semelle, pour établir sa courbure en fonction de Pécartement choisi pour les rails.According to another embodiment of the invention, the actuating cylinders of each lunatic sole of the curved section are distributed along the length of said sole, one of said cylinders being disposed at the mid-length of said sole, for establishing and stabilizing its position. relative to the frame of the conveyor device, the other cylinders being arranged laterally, one at each end of said sole, to establish its curvature according to the spacing chosen for the rails.
Toujours selon l'invention, les vérins latéraux sont fixés sur le bâti et sur la semelle, au moyen d'articulations appropriées, pour permettre un ajustement automatique de leurs positions quel que soit le rayon de courbure en vigueur. Selon une autre disposition de l'invention, les vérins de manœuvre des rails des tronçons rectilignes sont disposés à bonne distance des extrémités du tronçon courbe adjacent, laquelle distance est de l'ordre de une à une fois et demie celle séparant deux vérins adjacents sur ledit tronçon courbe.Still according to the invention, the lateral cylinders are fixed on the frame and on the sole, by means of appropriate hinges, to allow an automatic adjustment of their positions whatever the radius of curvature in force. According to another embodiment of the invention, the actuating cylinders of the rails of the rectilinear sections are arranged at a good distance from the ends of the adjacent curved section, which distance is of the order of one to one and a half times that separating two adjacent jacks on said curved section.
Toujours selon l'invention, des moyens de guidage sont interposés entre le bâti du convoyeur et chaque semelle pour permettre le mouvement desdites semelles sous l'effet des vérins de manœuvre tout en maintenant le rail correspondant dans son plan opérationnel.Still according to the invention, guiding means are interposed between the frame of the conveyor and each sole to allow the movement of said flanges under the effect of actuators while maintaining the corresponding rail in its operational plane.
Selon une autre disposition de l'invention, le dispositif convoyeur comporte des moyens d'assemblage des supports sur leur semelle correspondante, lesquels moyens d'assemblage permettent un déplacement dudit support par rapport à sa semelle, de façon à offrir une possibilité de calage initial desdits supports et par voie de conséquence des rails respectifs, l'un par rapport à l'autre.According to another embodiment of the invention, the conveyor device comprises means for assembling the supports on their corresponding soleplate, which assembly means allow a displacement of said support relative to its sole, so as to offer an initial possibility of calibration. said supports and consequently respective rails, relative to each other.
Toujours selon l'invention, le support de chaque rail est en matériau thermoplastique et sa section est en forme de h offrant une cavité ouverte qui fait office de rainure pour le corps du rail, laquelle rainure comporte, à son entrée, une bordure qui coopère avec une gorge aménagée dans ledit rail de façon à verrouiller ce dernier dans ladite rainure, laquelle rainure fait office de glissière pour ledit rail.

- la figure 3 représente la section d'un support de rail ;- Figure 3 shows the section of a rail support;
- la figure 4 représente la section d'un rail ;- Figure 4 shows the section of a rail;
- la figure 5 représente une section des extrémités de la partie courbe du rail extrados avec son support et la semelle. Le convoyeur représenté sur les figures 1 et 2 permet le transport d'articles divers et en particulier, comme représentées, de bouteilles (1).- Figure 5 shows a section of the ends of the curved portion of the extrados rail with its support and the sole. The conveyor shown in Figures 1 and 2 allows the transport of various items and in particular, as shown, bottles (1).
Ces bouteilles (1) comportent, au niveau de leur goulot (2), une collerette (3) qui se situe sous leur col (4) ; cette collerette (3) permet de supporter lesdites bouteilles et de les guider au moyen de rails (5) qui sont disposés de part et d'autre dudit goulot (2), lesquels rails sont dénommés, dans le langage du métier, « guides sous col ».These bottles (1) have, at their neck (2), a flange (3) which is located under their neck (4); this flange (3) supports said bottles and guide them by means of rails (5) which are arranged on either side of said neck (2), which rails are called, in the language of the trade, "guides under collar ".
Les bouteilles (1) peuvent avoir des formes et des dimensions variables ; elles sont transportées par séries, lots ou familles, grâce à ce type de convoyeur. Des opérations de réglage de l' écartement des rails (5) sont effectuées selon le diamètre du goulot (2) des bouteilles, sous la collerette (3), c'est à dire d ou D comme représenté figure 2, Les deux rails (5) sont parallèles entre eux et forment un couloir (6) qui permet de guider les bouteilles. Hs ont un écartement qui est le plus précis possible et constant ; la tolérance pour les écarts entre les rails (5) est de l'ordre du dixième de millimètre, voire de deux à trois dixièmes.The bottles (1) can have varying shapes and sizes; they are transported in series, batches or families, thanks to this type of conveyor. Rail spacing adjustment operations (5) are carried out according to the diameter of the neck (2) of the bottles, under the collar (3), ie d or D as shown in FIG. 2, the two rails ( 5) are parallel to each other and form a corridor (6) which guides the bottles. They have a spacing which is as precise as possible and constant; the tolerance for the gaps between the rails (5) is of the order of a tenth of a millimeter, or even two to three tenths.
Le col (4) de la bouteille est positionné dans une sorte de canal (7) aménagé pour permettre l'entraînement des bouteilles par soufflage, au moyen de jets d'air puisé, comme détaillé dans les documents précités. Ce canal (J) s'étend dans un caisson (8) partiellement représenté, et il comporte des ouïes (9) disposées latéralement, qui permettent la formation des jets d'air. Le caisson (8) contient l'air qui est maintenu sous pression par des moyens appropriés, non représentés, et cet air qui s'échappent des ouïes (9) pour propulser les bouteilles, fuit par le couloir (6), visible figure 1, qui est délimité par les rails (5).The neck (4) of the bottle is positioned in a sort of channel (7) arranged to allow the drive of the bottles by blowing, by means of pulsed air jets, as detailed in the aforementioned documents. This channel (J) extends in a box (8) partially shown, and it has gills (9) arranged laterally, which allow the formation of air jets. The box (8) contains the air which is kept under pressure by means appropriate, not shown, and this air escaping gills (9) to propel the bottles, leaks through the corridor (6), visible Figure 1, which is delimited by the rails (5).
Le canal (7) s'étend dans le caisson (8), au-dessus d'une paroi qui, dans le cas présent, fait office de bâti (10) pour les moyens détaillés ci-après et en particulier les moyens qui coopèrent avec les rails (5) pour en assurer la position de manière précise.The channel (7) extends in the box (8), above a wall which, in this case, serves as a frame (10) for the means detailed below and in particular the means that cooperate with the rails (5) to ensure the precise position.
Ces moyens sont constitués d'un support (11) qui se présente sous la forme d'un profilé réalisé en matériau theπnoplastique, et d'une semelle (12) qui est interposée entre ledit support (11) et le bâti (10). Le support (11) est fixé sur la semelle (12) de place en place au moyen d'organes d'assemblage (13) du genre vis écrou ; ce support est cependant aménagé avec des trous oblongs, par exemple, pour permettre son déplacement par rapport à ladite semelle (12) afin de pouvoir réaliser son calage sur cette dernière lors du réglage initial de récartement des rails (5). Cette possibilité de calage permet d'obtenir une précision raisonnable au niveau de récartement des rails (5).These means consist of a support (11) which is in the form of a profile made of theπnoplastique material, and a sole (12) which is interposed between said support (11) and the frame (10). The support (11) is fixed on the sole (12) of place in place by means of assembly members (13) of the screw nut type; this support is however arranged with oblong holes, for example, to allow its movement relative to said sole (12) to be able to make its wedging on the latter during the initial setting of the rails (5). This possibility of wedging makes it possible to obtain a reasonable accuracy in the level of the spacing of the rails (5).
La semelle (12) est solidaire du bâti (10) au moyen d'organes d'assemblage (14) qui sont solidaires du bâti (10). Ces organes d'assemblage (14) sont disposés dans une lumière (15) aménagée à la fois dans ladite semelle (12) et le support (11). Ces organes (14) d'assemblage maintiennent la semelle (12) en contact avec le dessous du bâti (10) et assurent son guidage ; ils procurent une certaine liberté de mouvement à cette semelle (12) et au support de rail, et en particulier une liberté de mouvement en translation par rapport audit bâti (10).The sole (12) is secured to the frame (10) by means of assembly members (14) which are integral with the frame (10). These assembly members (14) are arranged in a slot (15) arranged in both said sole (12) and the support (11). These assembly members (14) maintain the sole (12) in contact with the underside of the frame (10) and ensure its guidance; they provide a certain freedom of movement to this sole (12) and the rail support, and in particular a freedom of movement in translation relative to said frame (10).
Cette semelle (12) est associée à des moyens de manœuvre qui permettent de faire varier récartement entre les rails (5). Ces moyens de manœuvre sont constitués de vérins (16) qui sont représentés sous la forme de simples flèches indiquant la direction du mouvement qu'ils sont susceptibles d'imprimer à la semelle (12). Dans les parties rectilignes du convoyeur, les vérins (16) sont disposés perpendiculairement au sens de déplacement des bouteilles entre les rails (5). Dans la portion courbe du convoyeur, les vérins (16) sont disposés, d'une part, au centre, centrés sur l'axe médian (17) de ladite courbe et, d'autre part,aux extrémités, centrés sur des axes qui sont parallèles audit axe médian (17) ; les vérins disposés dans la partie centrale de la courbe sont repérés (16ci) pour le vérin de l'intrados et (16ce) pour le vérin de l'extrados et les vérins disposés aux extrémités sont repérés (16cie) et (16cee) respectivement pour l'intrados et l'extrados. Les vérins du centre de la courbe, repérés (16ci) et (16ce), participent au guidage radial et au positionnement des semelles (12ci) pour l'intrados et (12ce) pour l'extrados. Les deux vérins (16cie) et (16cee) situés aux extrémités des semelles (12ci) et (12ce) réalisent une correction du rayon de courbure desdites semelles selon leur position. Ds réalisent et maintiennent le positionnement des rails (5) lors du réglage de leur écartementThis sole (12) is associated with maneuvering means that allow to vary the spacing between the rails (5). These operating means consist of cylinders (16) which are represented in the form of simple arrows indicating the direction of movement that they are likely to print to the sole (12). In the rectilinear parts of the conveyor, the cylinders (16) are arranged perpendicularly to the direction of movement of the bottles between the rails (5). In the curved portion of the conveyor, the cylinders (16) are arranged, on the one hand, in the center, centered on the median axis (17) of said curve and, on the other hand, at the ends, centered on axes which are parallel to said median axis (17); the cylinders arranged in the central part of the curve are marked (16ci) for the cylinder of the intrados and (16ce) for the cylinder of the extrados and the cylinders arranged at the ends are marked (16cie) and (16cee) respectively for the intrados and the extrados. The cylinders of the center of the curve, marked (16ci) and (16ce), participate in radial guidance and positioning of the soles (12ci) for the intrados and (12ce) for the extrados. The two cylinders (16cie) and (16cee) located at the ends of the flanges (12ci) and (12ce) perform a correction of the radius of curvature of said flanges according to their position. Ds realize and maintain the positioning of the rails (5) when adjusting their spacing
Le déplacement des semelles (12) pour régler Pécartement entre les rails (5) génère un certain jeu entre les extrémités des semelles courbes et les extrémités adjacentes des semelles rectilignes.The displacement of the flanges (12) to adjust the spacing between the rails (5) generates a certain clearance between the ends of the curved soles and the adjacent ends of the straight flanges.
Lorsque Pécartement e est au minimum, comme représenté sur la partie gauche de la figure 1, un jeu apparaît entre les extrémités adjacentes des semelles (12) intrados.When the spacing e is at the minimum, as shown on the left-hand part of FIG. 1, a clearance appears between the adjacent ends of the inset flanges (12).
A l'inverse, lorsque Pécartement E est au maximum, comme représenté en haut de la figure 1, le jeu apparaît entre les extrémités adjacentes des semelles (12) extrados.Conversely, when the distance E is at the maximum, as shown at the top of Figure 1, the game appears between the adjacent ends of the soles (12) extrados.
Dans les deux cas, les rails (5) assurent une continuité et ils font la jonction entre les différentes semelles (12) soit de l'intrados, soit de l'extrados. Lorsque Pécartement e est au minimum, le rail (5) de l'intrados est mis en extension maximale par la semelle (12ci) de l'intrados.In both cases, the rails (5) provide continuity and they make the junction between the different soles (12) either of the intrados or extrados. When the spacing e is at the minimum, the rail (5) of the intrados is placed in maximum extension by the sole (12ci) of the intrados.
De la même façon, lorsque Pécartement E est au maximum, le rail (5) de l'extrados est mis en extension maximale par la semelle lunulaire (12ce) de l'extrados alors que le rail (5) de l'intrados est relâché. Pour obtenir cette extension des rails (5), aussi bien pour l'intrados que pour l'extrados, ces rails sont solidaires d'un support (11) qui leur offre une certaine liberté de mouvement, dans le sens longitudinal.In the same way, when the distance E is at the maximum, the rail (5) of the extrados is placed in maximum extension by the lunate sole (12ce) of the extrados while the rail (5) of the intrados is released. . To obtain this extension of the rails (5), both for the intrados and extrados, these rails are secured to a support (11) which gives them a certain freedom of movement in the longitudinal direction.
Le support (11) est réalisé en matériau thermoplastique. Comme représenté figure 3, sa section est en forme de h du fait de la présence d'un aménagement particulier pour loger le rail (5) qui est représenté figure 4 ; cet aménagement tient à la fois de la bride et de la glissière et se présente sous la forme d'une rainure (18) dans laquelle se loge le corps (19) dudit rail (5). L'entrée de cette rainure (18) forme un rétreint au moyen d'une petite bordure (20), laquelle bordure (20) coopère avec une gorge (21) aménagée entre le corps (19) du rail (5) et sa partie (22) en saillie qui forme le guide sous col. La surface portante (23) du rail (5) est située dans le même plan que la surface du support (11) qui est en contact avec la semelle (12).The support (11) is made of thermoplastic material. As shown in Figure 3, its section is h-shaped due to the presence of a special arrangement for housing the rail (5) which is shown in Figure 4; this arrangement is both the flange and the slide and is in the form of a groove (18) in which is housed the body (19) of said rail (5). The entrance of this groove (18) forms a narrowing by means of a small border (20), which edge (20) cooperates with a groove (21) arranged between the body (19) of the rail (5) and its part (22) projecting which forms the guide under collar. The bearing surface (23) of the rail (5) is located in the same plane as the surface of the support (11) which is in contact with the sole (12).
Le corps (19) du rail (5) est bridé dans la rainure (18) du support (11) tout en étant libre car cette rainure (18) forme en même temps une glissière. Le rail (5) peut ainsi s'allonger de façon élastique et cet allongement se répartit sur une certaine longueur du support (11). Dans le cas du rail (5) intrados, l'allongement peut être réparti à la fois sur le support (11) de la partie courbe et sur les supports (11) de la partie rectiligne du convoyeur. Dans le cas du rail (5) extrados, l'allongement s'effectue sur les supports (11) disposés de part et d'autre de la partie courbe, c'est-à-dire sur les supports (11) de la partie rectiligne du convoyeur. Le rail (5) est verrouillé à chacune des extrémités de la semelle (12ce) extrados de la partie courbe du convoyeur, comme représenté figure 5 ; il est verrouillé par rapport à son support (11), au moyen de vis (24), par exemple. Pour améliorer la capacité d'allongement des rails (5), ces derniers peuvent comporter des aménagements en forme de réduction de la quantité de matière par perçage ou par des découpes transversales partielles, non représentées.The body (19) of the rail (5) is flanged in the groove (18) of the support (11) while being free because this groove (18) forms at the same time a slide. The rail (5) can thus elongate elastically and this elongation is distributed over a certain length of the support (11). In the case of the intrados rail (5), the elongation can be distributed both on the support (11) of the curved portion and on the supports (11) of the rectilinear part of the conveyor. In the case of the extrados rail (5), the elongation takes place on the supports (11) arranged on either side of the curved part, that is to say on the supports (11) of the part rectilinear conveyor. The rail (5) is locked at each end of the sole (12ce) extrados of the curved portion of the conveyor, as shown in Figure 5; it is locked relative to its support (11) by means of screws (24), for example. To improve the elongation capacity of the rails (5), the latter may comprise arrangements in the form of reduction of the amount of material by drilling or by partial transverse cuts, not shown.
Lors de l'opération de réglage de Pécartement des rails (5), les vérins (16) sont mis en œuvre simultanément et en particulier les vérins (16ci et 16ce) disposés au centre de la partie courbe et les vérins (16) des parties rectilignes adjacentes. Les extrémités des parties rectilignes du convoyeur qui sont adjacentes aux extrémités des parties courbes, ne comportent pas de vérins. Ces extrémités se positionnent automatiquement sous l'effet du mouvement des vérins (16cie) et (16cee) qui sont situés aux extrémités de la courbe, et elles sont entraînées par les rails (5) correspondants. Les premiers vérins (16) disposés sur les parties rectilignes du convoyeur, se situent à une distance de l'entrée de la partie courbe qui est de l'ordre de une fois à une fois et demie la distance qui sépare deux vérins consécutifs de ladite partie courbe.During the adjustment of the spacing of the rails (5), the cylinders (16) are implemented simultaneously and in particular the cylinders (16ci and 16ce) arranged at the center of the curved part and the cylinders (16) of the parts rectilinear adjacent. The ends of the rectilinear parts of the conveyor which are adjacent to the ends of the curved parts, do not comprise cylinders. These ends are automatically positioned under the effect of the movement of the cylinders (16cie) and (16cee) which are located at the ends of the curve, and they are driven by the corresponding rails (5). The first cylinders (16) arranged on the rectilinear portions of the conveyor, are located at a distance from the entrance of the curved portion which is of the order of one to one and a half times the distance between two consecutive cylinders of said curved part.
L'obtention d'une grande précision pour le rayon de courbure des rails (5) de la partie courbe du convoyeur découle de la forme adoptée pour les semelles (12) de ladite partie courbe. Ces semelles (12) se présentent sous la forme d'une lame mince, en métal par exemple, dont le contour est du type lunulaire. La section de cette lame mince évolue de part et d'autre de sa partie médiane, donnant à la semelle (12) cette forme de lunule qui s'étend sur un quart de cercle. Cette section évolutive est choisie de façon à permettre une déformation élastique de la semelle sous l'effet des vérins (16cie) et (16cee) et surtout elle est choisie pour conférer à ladite semelle une courbure se rapprochant le plus possible de celle d'une portion de cercle ; le rayon de ce cercle est de l'ordre d'un mètre.The achievement of a high accuracy for the radius of curvature of the rails (5) of the curved portion of the conveyor follows from the shape adopted for the flanges (12) of said curved portion. These soles (12) are in the form of a thin blade, of metal for example, whose contour is of the lunar type. The section of this thin blade evolves on both sides of its middle part, giving the sole (12) this form of lunula which extends over a quarter circle. This evolutionary section is chosen so as to allow elastic deformation of the sole under the effect of the cylinders (16cie) and (16cee) and above all it is chosen to give said sole a curvature as close as possible to that of a portion of a circle; the radius of this circle is of the order of one meter.
Par ces moyens, le convoyeur peut accepter des familles de bouteilles très différentes, avec des diamètres dé goulot (2) évoluant entre 24 et 39 mm, par exemple. By these means, the conveyor can accept families of very different bottles, with neck diameters (2) ranging between 24 and 39 mm, for example.
