Description

La présente invention concerne un dispositif de transfert, en particulier pour piétons, entre deux éléments de transport disposés en prolongement l'un de l'autre, ainsi qu'un transporteur pour piétons équipé d'un tel dispositif de transfert.The present invention relates to a transfer device, in particular for pedestrians, between two transport elements arranged in extension of one another, as well as a pedestrian transporter equipped with such a transfer device.

On connaît des transporteurs comprenant une bande transporteuse continue réalisée en une matière déformable ou par une succession d'éléments à surface de transport sensiblement plane, permettant de transporter les piétons à une vitesse de transport supérieure à celle de la marche normale des piétons.Transporters are known comprising a continuous conveyor belt made of a deformable material or by a succession of elements with a substantially flat transport surface, making it possible to transport pedestrians at a transport speed greater than that of normal pedestrian walking.

De tels transporteurs nécessitent, entre l'entrée de la bande transporteuse et le plancher fixe d'entrée, un élément accélérateur permettant d'amener progressivement les piétons de la vitesse de marche normale à la vitesse plus élevée de la bande transporteuse et, entre la sortie de la bande transporteuse et le plancher fixe de sortie, un élément décélérateur permettant de ramener progressivement les piétons à la vitesse de marche normale.Such conveyors require, between the entrance of the conveyor belt and the fixed entrance floor, an accelerating element making it possible to gradually bring pedestrians from normal walking speed to the higher speed of the conveyor belt and, between exit from the conveyor belt and the fixed exit floor, a decelerating element allowing pedestrians to gradually return to normal walking speed.

Le document EP-A-0 509 861 décrit un transporteur du genre défini ci-dessus. Comme mentionné dans ce document antérieur, pour franchir la zone de transition entre la sortie de l'élément accélérateur et l'entrée de la bande transporteuse ou entre la sortie de la bande transporteuse et l'entrée de l'élément décélérateur, on prévoit une dénivelée permettant de franchir sans contact chaque zone de transition.The document EP-A-0 509 861 describes a transporter of the kind defined above. As mentioned in this prior document, to cross the transition zone between the exit of the accelerator element and the entry of the conveyor belt or between the exit of the conveyor belt and the entry of the decelerator element, provision is made for a uneven allowing to cross without contact each transition zone.

Cependant, une telle dénivelée occasionne au piéton une perte d'appui extrêmement gênante notamment pour des personnes à mobilité réduite, telles que des personnes handicapées.However, such an unevenness causes the pedestrian to lose support, which is extremely troublesome, in particular for people with reduced mobility, such as people with disabilities.

La présente invention propose un dispositif de transfert entre deux éléments de transport ainsi qu'un transporteur équipé d'un tel dispositif, permettant d'éliminer l'inconvénient ci-dessus des transporteurs connus.The present invention provides a transfer device between two transport elements and a transporter equipped with such a device, making it possible to eliminate the above drawback of known transporters.

A cet effet, le dispositif de transfert de l'invention, en particulier pour piétons, entre un premier élément de transport et un deuxième élément de transport disposés en prolongement l'un de l'autre, chaque élément comprenant une surface de transport des piétons sensiblement plane et des moyens de déplacement des piétons sur la surface de transport suivant une direction longitudinale, est caractérisé en ce qu'il comprend un élément de transfert à plateau, dont la surface d'appui des piétons, située sensiblement dans un même plan commun aux surfaces de transport des deux éléments de transport, comprend des moyens de roulement permettant le déplacement sans frottement des piétons du premier élément de transport au deuxième élément de transport, ou inversement.To this end, the transfer device of the invention, in particular for pedestrians, between a first transport element and a second transport element arranged in extension of one another, each element comprising a pedestrian transport surface substantially flat and means for moving pedestrians on the transport surface in a longitudinal direction, is characterized in that it comprises a transfer element with a platform, the pedestrian support surface of which is located substantially in the same common plane on the transport surfaces of the two transport elements, comprises rolling means allowing pedestrians to move without friction from the first transport element to the second transport element, or vice versa.

L'élément de transfert comprend une plaque à dents formant peigne s'engageant respectivement dans des rainures longitudinales de l'un et/ou de l'autre des éléments de transport, fixée au plateau de l'élément de transfert et dont la surface d'appui des piétons, située sur le même plan que celle du plateau, est également constituée de moyens de roulement.The transfer element comprises a tooth plate forming a comb respectively engaging in longitudinal grooves of one and / or the other of the transport elements, fixed to the plate of the transfer element and the surface of which d 'pedestrian support, located on the same plane as that of the platform, also consists of rolling means.

Selon un mode de réalisation préféré, les moyens de roulement comprennent des billes logées tournantes dans des trous borgnes correspondants du plateau de l'élément de transfert et de la plaque formant peigne en faisant saillie du plateau et de la plaque formant peigne de manière à définir les surfaces d'appui précitées des piétons.According to a preferred embodiment, the rolling means comprise balls housed rotating in corresponding blind holes of the plate of the transfer element and of the plate forming a comb by projecting from the plate and the plate forming comb so as to define the abovementioned bearing surfaces of pedestrians.

Avantageusement, les billes précitées sont maintenues dans les trous borgnes correspondants du plateau de l'élément de transfert par une plaque solidaire du plateau et comprenant des perçages traversés respectivement par les billes et d'un diamètre inférieur au diamètre des billes et les billes de la plaque formant peigne sont maintenues dans leurs trous borgnes correspondants respectivement par des rondelles plates à trous centraux tronconiques.Advantageously, the aforementioned balls are held in the corresponding blind holes of the plate of the transfer element by a plate integral with the plate and comprising holes pierced respectively by the balls and of a diameter less than the diameter of the balls and the balls of the comb plate are held in their corresponding blind holes respectively by flat washers with frustoconical central holes.

Selon un autre mode de réalisation, les moyens de roulement précités comprennent des rouleaux montés à rotation transversalement à la direction de déplacement des piétons dans des logements correspondants approximativement semi-cylindrique du plateau de l'élément de transfert et de la plaque formant peigne en faisant saillie de ce plateau de cette plaque de manière à définir les surfaces d'appui précitées des piétons.According to another embodiment, the aforementioned rolling means comprise rollers mounted for rotation transversely to the direction of movement of the pedestrians in corresponding approximately semi-cylindrical housings of the plate of the transfer element and of the plate forming a comb by making projection of this plate of this plate so as to define the abovementioned bearing surfaces of pedestrians.

Par ailleurs, le plateau de l'élément de transfert est d'une part supporté de façon pivotante sur un châssis de support par des pieds de support et d'autre fixé au châssis de support par deux éléments formant tirants situés de chaque côté du plateau à l'extérieur de la surface d'appui de celui-ci de façon à permettre un réglage d'inclinaison du plateau à une position selon laquelle la surface d'appui du plateau est située dans le plan commun aux surfaces de transport des deux éléments de transport.Furthermore, the plate of the transfer element is on the one hand pivotally supported on a support frame by support legs and on the other fixed to the support frame by two elements forming tie rods situated on each side of the plate. outside the bearing surface thereof so as to allow the tilting of the platform to be adjusted to a position in which the bearing surface of the platform is situated in the plane common to the transport surfaces of the two elements transport.

Avantageusement, les pieds de support du plateau de l'élément de transfert ont leurs extrémités libres logées respectivement dans des gorges inclinées transversales à la direction longitudinale de déplacement des piétons et réalisées respectivement dans des pièces de support solidaires du châssis du support, lesdites gorges transversales permettant un déplacement transversal par glissement de l'élément de transfert d'une faible quantité, de l'ordre de quelques millimètres, lorsque les rainures longitudinales de l'un et/ou de l'autre des éléments de transport heurtent les dents de la plaque formant peigne.Advantageously, the support feet of the tray of the transfer element have their free ends housed respectively in inclined grooves transverse to the longitudinal direction of movement of the pedestrians and produced respectively in support parts integral with the support frame, said transverse grooves allowing transverse displacement by sliding of the transfer element by a small amount, of the order of a few millimeters, when the longitudinal grooves of one and / or the other of the transport elements strike the teeth of the plate forming a comb.

Chaque élément formant tirant a une extrémité filetée ancrée dans un trou taraudé d'un premier axe transversal supporté par une chape solidaire du plateau de l'élément de transfert et son autre extrémité filetée traversant avec jeu un perçage d'un second axe transversal supporté par une chape solidaire d'une pièce de support fixée au châssis de support, deux écrous situés de part et d'autre du second axe transversal solidarisant l'autre extrémité filetée de l'élément formant tirant suivant un jeu axial de façon à permettre le pivotement vers le haut de l'élément de transfert autour des extrémités des pieds de support de celui-ci lorsqu'un objet se coince entre les rainures longitudinales de l'un ou l'autre des éléments de transport et les dents de la plaque formant peigne.Each tie-forming element has a threaded end anchored in a threaded hole of a first transverse axis supported by a yoke secured to the plate of the transfer element and its other threaded end passing through a hole in a second transverse axis supported by a yoke secured to a support piece fixed to the support frame, two nuts located on either side of the second transverse axis securing the other threaded end of the drawing element in an axial clearance so as to allow pivoting upwards of the transfer element around the ends of the support legs thereof when an object gets caught between the longitudinal grooves of one or other of the transport elements and the teeth of the comb plate .

Chaque pièce de support de la chape du second axe transversal comprend une gorge inclinée transversale de support de l'extrémité d'une patte de support de l'élément de transfert.Each support piece of the yoke of the second transverse axis comprises a transverse inclined groove for supporting the end of a support tab of the transfer element.

L'invention propose également un transporteur, en particulier pour piétons, comprenant un élément de transport principal du type à bande transporteuse prolongé, à chacune de ses extrémités, par un élément de transport pouvant fonctionner comme élément d'accélération ou de décélération entre l'élément de transport principal et un plancher fixe de chargement ou de déchargement des piétons, et qui est caractérisé en ce qu'il comprend un dispositif de transfert tel que défini précédemment et disposé entre l'élément d'accélération ou de décélération et l'élément de transport principal.The invention also provides a conveyor, in particular for pedestrians, comprising a main transport element of the conveyor belt type extended, at each of its ends, by an element transport capable of functioning as an acceleration or deceleration element between the main transport element and a fixed pedestrian loading or unloading floor, and which is characterized in that it comprises a transfer device as defined above and disposed between the acceleration or deceleration element and the main transport element.

Afin d'amener les piétons de leur vitesse normale de marche à la vitesse relativement élevée de la bande 3 et de ramener les piétons de la vitesse de la bande 3 à leur vitesse normale de marche, le transporteur comprend également un élément d'accélération 5 disposé entre le plancher fixe d'entrée 1 et l'entrée de la bande transporteuse 3 définie relativement au sens de déplacement de celle-ci et un élément de décélération 6 disposé entre la sortie de la bande transporteuse 3 et le plancher fixe de sortie 2.The conveyor belt 3 moves at a higher speed than the normal walking speed of a pedestrian. In order to bring pedestrians from their normal walking speed to the relatively high speed of lane 3 and to bring pedestrians from the speed of lane 3 to their normal walking speed, the transporter also includes an acceleration element 5 disposed between the fixed inlet floor 1 and the inlet of the conveyor belt 3 defined relative to the direction of movement of the latter and a deceleration element 6 disposed between the outlet of the conveyor belt 3 and the fixed outlet floor 2 .

Pour permettre aux piétons de franchir sans perte d'équilibre la zone de transition située entre l'élément d'accélération 5 et la bande transporteuse 3 ou entre la bande transporteuse 3 et l'élément de décélération 6, un élément de transfert 8 est disposé entre l'élément d'accélération 5 et la bande transporteuse 3 ou entre la bande transporteuse 3 et l'élément de décélération 6.To allow pedestrians to cross the transition zone between the acceleration element 5 and the conveyor belt 3 or between the conveyor belt 3 and the deceleration element 6 without loss of balance, a transfer element 8 is arranged between the acceleration element 5 and the conveyor belt 3 or between the conveyor belt 3 and the deceleration element 6.

Conformément à l'invention, comme représenté en particulier aux figures 2 et 3, chaque élément de transfert 8 comprend un plateau 9, dont la surface d'appui S2 des piétons est située sensiblement dans un même plan commun à la surface de transport S1 de l'élément d'accélération 5 ou de décélération 6 et à la surface de transport de la bande transporteuse 3 et comprend des moyens de roulement 10 permettant le déplacement pratiquement sans frottement des piétons de l'élément d'accélération 5 à la bande transporteuse ou de la bande transporteuse 3 à l'élément de décélération 6.In accordance with the invention, as shown in particular in FIGS. 2 and 3, each transfer element 8 comprises a plate 9, the bearing surface S2 of the pedestrians of which is situated substantially in the same plane common to the transport surface S1 of the acceleration element 5 or deceleration element 6 and on the transport surface of the conveyor belt 3 and comprises rolling means 10 allowing the pedestrian movement of the acceleration element 5 practically without friction from the conveyor belt or from the conveyor belt 3 to the deceleration element 6.

L'élément de transfert 8 comprend une plaque en peigne 11, dont les dents 12 s'engagent respectivement dans des rainures longitudinales 13 de la bande transporteuse 3 définies entre des nervures 14 de celle-ci. La plaque formant peigne 11 est fixée sur le plateau 9 de l'élément de transfert 8, par exemple par des vis de fixation 15 et a sa surface d'appui S3 des piétons située dans le même plan que la surface d'appui S2 du plateau 9 et est également constituée de moyens de roulement 16 permettant le déplacement pratiquement sans frottement des piétons de la plaque formant peigne 11 à la bande transporteuse 3, ou inversement.The transfer element 8 comprises a comb plate 11, the teeth 12 of which respectively engage in longitudinal grooves 13 of the conveyor belt 3 defined between ribs 14 of this one. The comb plate 11 is fixed to the plate 9 of the transfer element 8, for example by fixing screws 15 and has its pedestrian support surface S3 located in the same plane as the support surface S2 of the plate 9 and also consists of rolling means 16 allowing the movement of pedestrians practically without friction from the plate forming a comb 11 to the conveyor belt 3, or vice versa.

De préférence, les moyens de roulement du plateau 9 et de la plaque formant peigne 11 sont constitués par des billes 10, 16, les billes 10 étant logées dans des trous borgnes correspondants 17 du plateau 9, tandis que les billes 16 sont logées dans des trous borgnes correspondants 18 de la plaque formant peigne 11 comme cela ressort mieux de la figure 5.Preferably, the rolling means of the plate 9 and of the comb plate 11 consist of balls 10, 16, the balls 10 being housed in corresponding blind holes 17 of the plate 9, while the balls 16 are housed in corresponding blind holes 18 of the comb plate 11 as can be seen better from FIG. 5.

Les billes 10, 16 sont maintenues dans leurs trous respectifs 17, 18 en faisant saillie du plateau 9 et de la plaque formant peigne 11 de manière à définir les surfaces d'appui S2 et S3 et tournent sur elles-mêmes dans ces logements lors du passage des piétons.The balls 10, 16 are held in their respective holes 17, 18 by projecting from the plate 9 and from the plate forming a comb 11 so as to define the bearing surfaces S2 and S3 and rotate on themselves in these housings during the pedestrian crossing.

Plus précisément, les billes 10 sont maintenues dans leurs trous borgnes correspondants 17, réalisés dans une plaque 9a rapportée dans le plateau 9 de l'élément de transfert 8 et fixée à celui-ci par des vis 9b, par une plaque 19 fixée à la plaque 9a, par exemple par des vis de fixation 20, la plaque 19 comprenant des perçages 21 traversés respectivement par les billes 10 et d'un diamètre inférieur au diamètre de celles-ci.More specifically, the balls 10 are held in their corresponding blind holes 17, produced in a plate 9a attached to the plate 9 of the transfer element 8 and fixed to the latter by screws 9b, by a plate 19 fixed to the plate 9a, for example by fixing screws 20, the plate 19 comprising holes 21 crossed respectively by the balls 10 and of a diameter less than the diameter of the latter.

Les billes 16 sont maintenues dans les trous borgnes correspondants 18 de la plaque formant peigne 11 respectivement par des rondelles plates 22, chacune logée dans un lamage 23 usiné dans la plaque 11, chaque rondelle 22 ayant son trou central tronconique 22a en appui sur la bille 16.The balls 16 are held in the corresponding blind holes 18 of the comb plate 11 respectively by flat washers 22, each housed in a countersink 23 machined in the plate 11, each washer 22 having its frustoconical central hole 22a resting on ball 16.

Selon une variante de réalisation non représentée, les moyens de roulement 10, 16 peuvent être constitués par des rouleaux montés transversalement à la direction longitudinale de la bande transporteuse 3 dans des logements correspondants approximativement semi-cylindriques du plateau 9 de l'élément de transfert 8 et de la plaque formant peigne 11 en faisant saillie du plateau 9 et de la plaque 11 de manière à définir les surfaces d'appui S2 et S3 des piétons.According to an alternative embodiment not shown, the rolling means 10, 16 can be constituted by rollers mounted transversely to the longitudinal direction of the conveyor belt 3 in corresponding approximately semi-cylindrical housings of the plate 9 of the transfer element 8 and the comb plate 11 projecting from the plate 9 and the plate 11 so as to define the bearing surfaces S2 and S3 of the pedestrians.

Par ailleurs, le plateau 9 de l'élément de transfert 8 est supporté de façon pivotante sur un châssis de support 24 par des pieds de support 25 disposés symétriquement à l'axe longitudinal XX' de la bande 3 et dont les extrémités libres 25a sont logées respectivement dans des gorges inclinées 26 respectivement de pièces de support 27, 28 solidaires du châssis 24, les gorges 26 étant alignées transversalement à l'axe longitudinal XX' de la bande transporteuse 3. Deux pièces de support 27 sont disposées symétriquement à l'axe longitudinal XX' de la bande 3 et sont fixées sur une aile d'une traverse 29 en L inversé par des vis de fixation 30, la traverse 29 étant solidaire, par exemple par soudage, du châssis 24.Furthermore, the plate 9 of the transfer element 8 is pivotally supported on a support frame 24 by support legs 25 arranged symmetrically to the longitudinal axis XX 'of the strip 3 and whose free ends 25a are housed respectively in inclined grooves 26 respectively of support pieces 27, 28 integral with the chassis 24, the grooves 26 being aligned transversely to the longitudinal axis XX 'of the conveyor belt 3. Two support pieces 27 are arranged symmetrically to the longitudinal axis XX ′ of the strip 3 and are fixed to a wing of a cross member 29 in an L inverted by fixing screws 30, the cross member 29 being secured, for example by welding, to the chassis 24.

Le plateau 9 de chaque élément de transfert 8 est bilatéralement fixé au châssis de support 24 par deux éléments formant tirants 31 disposés symétriquement à l'axe XX' à l'extérieur de la surface d'appui S2 du plateau 9 de façon à permettre un réglage d'inclinaison de ce plateau à une position selon laquelle la surface d'appui S2 est située dans le plan commun aux surfaces de transport respectivement de l'élément d'accélération 5 ou de décélération 6 et de la bande transporteuse 3.The plate 9 of each transfer element 8 is bilaterally fixed to the support frame 24 by two tie-rod elements 31 arranged symmetrically to the axis XX 'outside the bearing surface S2 of the plate 9 so as to allow tilt adjustment of this plate to a position according to which the support surface S2 is located in the plane common to the surfaces transporting the acceleration element 5 or deceleration element 6 and the conveyor belt 3, respectively.

Chaque élément formant tirant 31, parallèle à l'axe XX', a une partie d'extrémité filetée 31a ancrée dans un trou taraudé correspondant 32a traversant un axe transversal 32 supporté par une chape 33 solidaire d'une partie extrême 9c du plateau 9 de l'élément de transfert 8, laquelle partie 9c comporte également une patte de support 25 dont l'extrémité libre inférieure est engagée dans la gorge 26 de la pièce de support correspondante 28 fixée sur la traverse 29 par des vis de fixation (non représentées). L'élément formant tirant 31 a son autre partie d'extrémité filetée 31b traversant avec jeu un perçage 34a réalisé à travers un autre axe transversal 34 supporté par une chape 35 de la pièce de support 28. Deux écrous 36, 37 sont vissés sur la partie filetée 31b de l'élément formant tirant 31 de part et d'autre de l'axe transversal 34 de façon à solidariser cette partie filetée à l'axe 34. Cependant, l'écrou 37 n'est pas totalement serré contre l'axe 34 et laisse subsister un jeu j d'environ 2 millimètres de façon à permettre un léger pivotement de l'élément de transfert 8 autour des extrémités libres des pattes de support 25 dans un sens tendant à écarter vers le haut, au vu de la figure 3, la plaque formant peigne 11 de la bande transporteuse 3. Un tel pivotement se produit lorsqu'un objet se coince entre les rainures longitudinales 13 de la bande transporteuse 3 et les dents 12 de la plaque formant peigne 11 et permettant à l'élément de transport 8 d'actionner un élément contacteur destiné à commander l'arrêt du rouleau moteur 4 d'entraînement de la bande transporteuse 3. Autrement, l'élément de transfert 8 est maintenu en position fixe par les éléments formant tirants 31 qui comprennent chacun un écrou central 31c permettant de régler précisément la position des surfaces d'appui S2 et S3 de l'élément de transfert 8 relativement aux surfaces de transport de l'élément d'accélération 5 ou de décélération 6 et de la bande transporteuse 3. La figure 3 montre que les surfaces d'appui S2, S3 de chaque élément de transfert 8 peuvent être décalées en dessous de la surface de transport de la bande transporteuse 3 jusqu'à une valeur d'environ 5 millimètres sans qu'un déséquilibre soit infligé aux piétons franchissant la très petite zone de transition entre l'extrémité de la plaque formant peigne 11 et la bande transporteuse 3.Each drawing element 31, parallel to the axis XX ′, has a threaded end part 31a anchored in a corresponding tapped hole 32a crossing a transverse axis 32 supported by a yoke 33 secured to an end part 9c of the plate 9 of the transfer element 8, which part 9c also includes a support tab 25, the lower free end of which is engaged in the groove 26 of the corresponding support piece 28 fixed to the cross-member 29 by fixing screws (not shown) . The drawing element 31 has its other threaded end portion 31b passing through a hole 34a made through another transverse axis 34 supported by a yoke 35 of the support piece 28. Two nuts 36, 37 are screwed onto the threaded part 31b of the pulling element 31 on either side of the transverse axis 34 so as to secure this threaded part to the axis 34. However, the nut 37 is not fully tightened against the axis 34 and leaves a clearance j of approximately 2 millimeters so as to allow a slight pivoting of the transfer element 8 around the free ends of the support legs 25 in a direction tending to spread upwards, in view of the Figure 3, the comb plate 11 of the conveyor belt 3. Such pivoting occurs when an object gets caught between the longitudinal grooves 13 of the conveyor belt 3 and the teeth 12 of the comb plate 11 and allowing the transport element 8 actuating a contactor element intended to control the stopping of the drive roller 4 for driving the conveyor belt 3. Otherwise, the transfer element 8 is held in a fixed position by the tie-rod elements 31 which each comprise a central nut 31c allowing precise adjustment of the position of the bearing surfaces S2 and S3 of the transfer element 8 relative to the transport surfaces of the acceleration element 5 or deceleration element 6 and of the conveyor belt 3. FIG. 3 shows that the bearing surfaces S2, S3 of each transfer element 8 can be offset below the transport surface of the conveyor belt 3 to a value of approximately 5 millimeters without an imbalance being inflicted on pedestrians crossing the very small transition zone between the end of the comb plate 11 and the conveyor belt 3.

Les gorges transversales 26 des pièces de support 27 et 28 permettent un déplacement transversal de l'élément de transfert 8 par glissement des extrémités libres 25a des pattes de support 25 dans ces gorges d'une faible quantité, de l'ordre de quelques millimètres, lorsque les rainures longitudinales 13 de la bande transporteuse 3 heurtent les dents 12 de la plaque formant peigne 11. Ce léger flottement transversal de l'élément de transfert 8 permet de compenser une dérive latérale éventuelle au-delà de la valeur de décalage d (figure 2) entre la bande transporteuse 3 et le rouleau correspondant 4. Pour permettre un tel déplacement transversal, chaque axe transversal 34 est monté dans deux trous oblongs (non représentés) de la chape 35 s'étendant parallèlement à l'axe XX' de la bande transporteuse 3.The transverse grooves 26 of the support pieces 27 and 28 allow transverse movement of the transfer element 8 by sliding the free ends 25a of the support tabs 25 in these grooves by a small amount, of the order of a few millimeters, when the longitudinal grooves 13 of the conveyor belt 3 strike the teeth 12 of the comb plate 11. This slight transverse floating of the transfer element 8 makes it possible to compensate for any lateral drift beyond the offset value d (FIG. 2) between the conveyor belt 3 and the corresponding roller 4. To allow such transverse movement, each transverse axis 34 is mounted in two oblong holes (not shown) of the yoke 35 extending parallel to the axis XX 'of the conveyor belt 3.

Le dispositif de transfert ci-dessus décrit de l'invention est d'une structure extrêmement simple, ne nécessite aucun changement de niveau dans la zone de transition entre un élément d'accélération ou un élément de décélération et la bande transporteuse et permet une réversibilité de fonctionnement du transporteur à bande, c'est-à-dire que le déplacement de la bande transporteuse peut s'effectuer dans un sens ou dans l'autre. Le dispositif de transfert de l'invention peut être utilisé dans des transporteurs dit "trottoirs roulants", où la bande transporteuse est constituée d'éléments s'enchaînant les uns aux autres. Enfin, le dispositif de transfert de l'invention peut être implanté entre deux bandes transporteuses alignées en prolongement l'une de l'autre ou décalées l'une par rapport à l'autre en formant un angle dans lequel serait disposé le dispositif de transfert, ce dernier comprenant deux plaques extrêmes formant peigne dont les dents sont engagées dans les rainures longitudinales respectivement des deux bandes transporteuses.The transfer device described above of the invention is of an extremely simple structure, does not require any change in level in the transition zone between an acceleration element or a deceleration element and the conveyor belt and allows reversibility operating belt conveyor, that is to say the movement of the conveyor belt can be carried out in one direction or the other. The transfer device of the invention can be used in so-called "moving walkways" conveyors, where the conveyor belt is made up of elements which are linked together. Finally, the transfer device of the invention can be installed between two conveyor belts aligned in extension of one another or offset with respect to each other by forming an angle in which the transfer device would be arranged. , the latter comprising two end plates forming a comb whose teeth are engaged in the longitudinal grooves respectively of the two conveyor belts.
