Abstract
Description
L'invention concerne, de façon générale, les transporteurs motorisés, dotés d'une infrastructure fixe.The invention relates generally to motorized carriers, with fixed infrastructure.
Plus précisément, l'invention concerne un dispositif de transfert passif entre deux organes d'entraínement actifs d'un système de transport, tel qu'un trottoir roulant, propre à imprimer, par exemple à des piétons, une translation suivant une direction longitudinale, ce dispositif de transfert étant interposé entre les deux organes d'entraínement suivant la direction longitudinale et comprenant un châssis s'étendant suivant une direction transversale perpendiculaire à la direction longitudinale, ainsi que des moyens de roulement, supportés par le châssis et définissant une surface de roulement reliant les deux organes d'entraínement.More specifically, the invention relates to a device for passive transfer between two active drive units a transport system, such as a moving sidewalk, suitable for printing, for example to pedestrians, a translation in a longitudinal direction, this transfer device being interposed between the two drive members in the longitudinal direction and comprising a frame extending in a direction transverse perpendicular to the longitudinal direction, as well as rolling means, supported by the chassis and defining a running surface connecting the two drive bodies.
Un dispositif de ce type est par exemple décrit dans le brevet européen EP 0 803 464.A device of this type is for example described in the European patent EP 0 803 464.
Comme l'expose ce brevet, un tel dispositif de transfert a pour fonction de permettre le déplacement transitoire d'une charge donnée, par exemple d'un piéton, entre deux organes d'entraínement fonctionnant à des vitesses respectives différentes, de manière que l'accélération positive ou négative subie par la charge transportée soit minimale.As this patent explains, such a transfer device has the function of allowing transient displacement of a given load, for example of a pedestrian, between two drive members operating at speeds respective ones, so that the acceleration positive or negative undergone by the load transported either minimal.
De tels dispositifs, qui sont généralement installés dans des lieux publics, sont soumis à des conditions de fonctionnement extrêmes et doivent de ce fait être construits de façon très robuste. Such devices, which are usually installed in public places, are subject to conditions of extreme operation and must therefore be very robustly constructed.
Dans cette optique, le brevet précité préconise l'emploi, en tant que moyens de roulement, de billes ou de galets roulant dans des logements sensiblement semi-sphériques ou semi-cylindriques.In this perspective, the aforementioned patent recommends the use, as rolling means, balls or rollers traveling in substantially semi-spherical housings or semi-cylindrical.
L'invention, qui se situe dans ce contexte, a pour but de proposer un dispositif de transfert de structure simple, de construction robuste, et de surcroít capable d'offrir, dans la surface de roulement, une meilleure surface roulante que le dispositif de l'art antérieur.The invention, which is situated in this context, aims to propose a simple structure transfer device, robust construction, and moreover capable of offering, in the running surface, a better surface rolling than the device of the prior art.
A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend une pluralité de voiles dont chacun est solidaire du châssis et s'étend dans un plan perpendiculaire à la direction transversale jusqu'à un bord supérieur disposé en retrait de la surface de roulement, et une pluralité d'axes dont chacun s'étend parallèlement à la direction transversale et traverse au moins deux voiles adjacents, et en ce que les moyens de roulement comprennent une pluralité de galets agencés en une pluralité de rangées successives, adjacentes suivant la direction longitudinale, chaque galet étant monté à rotation sur un desdits axes.To this end, the device of the invention, moreover conforms to the generic definition given by the preamble above, is essentially characterized by what it includes a plurality of sails each of which is integral with the chassis and extends in a plane perpendicular to the transverse direction up to a upper edge set back from the surface of bearing, and a plurality of axes each of which extends parallel to the transverse direction and crosses at minus two adjacent sails, and in that the means of bearing comprise a plurality of rollers arranged in a plurality of successive rows, adjacent according to the longitudinal direction, each roller being mounted at rotation on one of said axes.
De préférence, chaque rangée de galets comprend un ou plusieurs galets empilés de façon coaxiale suivant la direction transversale.Preferably, each row of rollers comprises one or several rollers stacked coaxially according to the transverse direction.
Chaque galet peut être monté en rotation sur son axe par l'intermédiaire d'un palier à billes, à rouleaux ou à bagues. Each roller can be rotatably mounted on its axis by via a ball, roller or roller bearing rings.
Dans le dispositif de transfert de l'invention, certains au moins des galets peuvent avoir un diamètre externe différent.In the transfer device of the invention, certain at least rollers can have an external diameter different.
Selon son mode de réalisation préféré, le dispositif de transfert de l'invention comprend une pluralité de supports élémentaires alignés suivant la direction transversale, chaque support élémentaire étant rendu solidaire du châssis et portant au moins deux voiles mutuellement parallèles.According to its preferred embodiment, the transfer of the invention includes a plurality of elementary supports aligned in the direction transverse, each elementary support being rendered secured to the chassis and carrying at least two sails mutually parallel.
Les supports élémentaires sont avantageusement alignés de façon jointive suivant la direction transversale, et forment une rangée unique suivant la direction longitudinale.The elementary supports are advantageously aligned by joined in the transverse direction, and form a single row in the direction longitudinal.
Chaque support élémentaire présente par exemple, en aval des voiles suivant la direction longitudinale, un bec à section sensiblement triangulaire dont une surface supérieure plonge sous la surface de roulement et s'en éloigne à distance croissante des voiles.Each elementary support presents for example, downstream sails in the longitudinal direction, a spout substantially triangular section including a surface upper dives under the running surface and away from the sails at an increasing distance.
Chaque bec peut présenter une surface inférieure et un bord aval conformés en peigne et imbriqués dans le deuxième organe d'entraínement.Each spout may have a lower surface and a downstream edge comb-shaped and nested in the second drive body.
Le montage et la maintenance du dispositif de transfert de l'invention peuvent être optimisés en montant chaque support élémentaire de façon amovible sur le châssis, ce dernier présentant lui-même deux extrémités équipées de moyens respectifs de montage sur une infrastructure fixe.Installation and maintenance of the transfer device of the invention can be optimized by mounting each elementary support removably on the chassis, this last presenting itself two ends fitted with respective means of mounting on a fixed infrastructure.

Comme annoncé précédemment, l'invention concerne un dispositif de transfert destiné à venir s'intégrer dans un système de transport, tel qu'un trottoir roulant, permettant notamment à des piétons d'être déplacés par translation suivant une direction longitudinale L.As previously announced, the invention relates to a transfer device intended to be integrated into a transport system, such as a moving sidewalk, allowing in particular pedestrians to be moved by translation in a longitudinal direction L.
Un tel système comprend typiquement un premier organe d'entraínement actif 1, par exemple un rouleau motorisé, un deuxième organe d'entraínement actif 2, par exemple une bande sans fin mue par un autre rouleau motorisé, le dispositif de transfert de l'invention étant passif, c'est-à-dire non motorisé lui-même, et interposé entre les deux organes d'entraínement actifs 1 et 2 suivant la direction longitudinale L. Such a system typically includes a first member active drive 1, for example a motorized roller, a second active drive member 2, for example an endless belt driven by another motorized roller, the transfer device of the invention being passive, that is to say not motorized itself, and interposed between the two active drive members 1 and 2 according to the longitudinal direction L.

T, perpendiculaire à la direction longitudinale L.The
A chacune de ses extrémités, ce châssis 3 est doté de
moyens de montage 30 permettant de le fixer à une

supportés par le châssis 3 et définissent une surface de
roulement R.The rolling
Comme le montre plus précisément la figure 1, la surface de roulement R relie les deux organes d'entraínement 1 et 2, et est sensiblement coplanaire avec les surfaces supérieures de transport respectivement définies par les organes d'entraínement 1 et 2.As shown more precisely in Figure 1, the surface bearing R connects the two drive members 1 and 2, and is substantially coplanar with the surfaces of transport respectively defined by drive units 1 and 2.
Au lieu d'être constitués par des billes ou des galets
roulant dans des logements respectifs comme dans le
dispositif connu, les moyens de roulement 4 du dispositif
de transfert de l'invention sont constitués par des
galets montés à rotation sur des axes.Instead of being made up of balls or pebbles
driving in respective housing as in the
known device, the
Pour ce faire, ce dispositif comprend tout d'abord une
pluralité de voiles, tels que 51 à 54, dont chacun est
solidaire du châssis 3 et s'étend dans un plan
perpendiculaire à la direction transversale T.To do this, this device firstly comprises a
plurality of sails, such as 51 to 54, each of which is
integral with the
Chaque voile est limité par un bord supérieur, tel que 510 à 540, qui est disposé en retrait par rapport à la surface de roulement R, c'est-à-dire au-dessous de cette surface lorsque le dispositif de transfert est horizontal.Each sail is limited by an upper edge, such as 510 to 540, which is set back from the rolling surface R, that is to say below this surface when the transfer device is horizontal.
Ce dispositif comprend par ailleurs une pluralité d'axes, tels que 61 à 66, dont chacun s'étend parallèlement à la direction transversale T et traverse au moins deux voiles adjacents, tels que 51 et 52.This device also comprises a plurality of axes, such as 61 to 66, each of which extends parallel to the transverse direction T and crosses at least two sails adjacent, such as 51 and 52.
Enfin, chaque galet 4 est monté à rotation sur l'un des
axes 61 à 66, les galets 4 étant collectivement agencés
pour former un ensemble de plusieurs rangées successives,
référencées 41 à 46 et mutuellement adjacentes suivant la
direction longitudinale L.Finally, each

7 dont chacun est fixé au châssis 3 de façon amovible,
par exemple au moyen de vis telles que 8 engagées dans
des orifices 710 pratiqués dans une paroi de fond 71 de
ce support 7.As best shown in Figures 1 and 3, the sails
are advantageously carried by
Les supports élémentaires 7 sont fixés au châssis 3 de
manière à être alignés de façon jointive suivant la
direction transversale T, et à former une rangée unique
suivant la direction longitudinale L.The

voiles, et par exemple quatre voiles 51 à 54 comme
illustré sur les figures.Each elementary support can include more than two
sails, and for example four

galets, telles que 41 à 46, comprenne plusieurs galets 4
empilés de façon coaxiale suivant la direction
transversale T, y compris sur un même support élémentaire

externe différent, et chaque galet peut être monté à
rotation sur son axe, tel que 61 à 66, par
l'intermédiaire d'un palier à billes, à rouleaux ou à
bagues.At least some of the

bec 70 à section sensiblement triangulaire disposé en
aval, suivant la direction longitudinale L, par rapport à
la paroi de fond 71 de ce support et aux voiles 51 à 54
qui s'étendent à partir de celle-ci.Each
Comme le montre notamment la figure 1, le bec 70 peut
être conformé de façon telle que sa surface supérieure
700 plonge sous la surface de roulement R et s'en éloigne
à distance croissante des voiles 51 à 54, cet agencement
favorisant le transfert de la charge transportée vers le
second organe d'entraínement 2.As shown in particular in Figure 1, the
