Abstract

A conveyor device for conveying flat objects on edge, which device comprises at least two wheels having elastically deformable treads and disposed facing each other so as to move a flat object on edge by pinching and friction. The two wheels are arranged in such a manner as to exert a pinching force on the flat object on edge that varies progressively as the flat object is driven forwards.

Description

Convoyeur à roues déformables exerçant un effort de pincement progressif Conveyor with deformable wheels exerting a progressive clamping force
L'invention porte sur un dispositif de convoyage d'objets plats comprenant au moins un couple de roues à bande de roulement déformable élastiquement qui sont disposées en opposition de manière à déplacer un objet plat par pincement et friction.The invention relates to a device for conveying flat objects comprising at least one pair of wheels with elastically deformable tread which are arranged in opposition so as to move a flat object by pinching and friction.
L'invention porte plus particulièrement sur un dispositif de convoyage apte à déplacer un large spectre d'envois postaux plats allant des coupons de très faible épaisseur (de l'ordre de 0,5 mm) à des objets plats de grand format et de très grande épaisseur (de l'ordre de 30 mm).The invention relates more particularly to a conveying device capable of moving a wide spectrum of flat mail items ranging from coupons of very small thickness (of the order of 0.5 mm) to flat objects of large size and very large thickness (of the order of 30 mm).
On connaît du document de brevet européen EP-1194249 un tel dispositif de convoyage qui fait partie d'un système plus complexe appelé « synchronisateur » dans une machine de tri postal.European patent document EP-1194249 discloses such a conveyor device which forms part of a more complex system called a "synchronizer" in a postal sorting machine.
Ce synchronisateur comporte plusieurs étages à deux niveaux de roues motorisées accouplées, lesquelles ont une vitesse de rotation qui est contrôlée pour synchroniser le déplacement d'un envoi postal (inséré entre les roues accouplées en opposition) avec le déplacement d'un godet d'un carrousel à godets dans lequel cet envoi doit être injecté. Dans cet agencement connu, chaque envoi courant est poussé entre les roues de l'étage d'entrée du synchronisateur par un organe de dépilage qui est dans le cas présent une courroie perforée déplacée devant une buse d'aspiration.This synchronizer has several stages with two levels of coupled motorized wheels, which have a rotational speed which is controlled to synchronize the movement of a mailpiece (inserted between the mated wheels in opposition) with the displacement of a bucket of a bucket carousel in which this shipment is to be injected. In this known arrangement, each current mail is pushed between the wheels of the input stage of the synchronizer by an unstacking member which is in this case a perforated belt moved in front of a suction nozzle.
La commande du synchronisateur prend en compte l'instant de passage de l'envoi courant devant un capteur placé à l'entrée du synchronisateur et l'instant de passage d'un godet (dans lequel doit être injecté l'envoi) devant un autre capteur placé le long du chemin de circulation des godets.The control of the synchronizer takes into account the instant of passage of the current item in front of a sensor placed at the input of the synchronizer and the moment of passage of a bucket (in which the sending must be injected) in front of another sensor placed along the bucket circulation path.
A partir d'une vitesse de déplacement relativement constante de l'envoi entre la sortie du synchronisateur et le point d'injection dans un godet, on calcule une courbe d'accélération de la vitesse de l'envoi dans le synchronisateur pour faire coïncider le passage du godet avec l'arrivée de l'envoi. En pratique, en sortie du synchronisateur les envois se suivent en série avec un écart constant entre leur bord avant qui correspond à un écart entre quatre godets consécutifs du carrousel.From a relatively constant speed of displacement of the sending between the output of the synchronizer and the point of injection in a bucket, an acceleration curve of the speed of the sending in the synchronizer is calculated to make coincide the passage of the bucket with the arrival of the consignment. In practice, at the output of the synchronizer the sendings follow each other in series with a constant gap between their front edge which corresponds to a gap between four consecutive cups of the carousel.
Dans ce synchronisateur, l'étage d'entrée est formé d'au moins deux roues en opposition, ces roues ayant une bande de roulement déformable élastiquement de même diamètre. Les deux roues sont en contact l'une avec l'autre par la surface extérieure des bandes de roulement.In this synchronizer, the input stage is formed of at least two wheels in opposition, these wheels having an elastically deformable tread of the same diameter. The two wheels are in contact with each other by the outer surface of the treads.
Quand un envoi est inséré sur chant entre les roues en opposition de l'étage d'entrée, son front avant vient déformer les bandes de roulement des roues en opposition sensiblement sur la ligne de contact des bandes de roulement. En s'effaçant, les bandes de roulement des roues en opposition exercent sur les surfaces opposées de l'envoi un effort de pincement qui est réparti sur pratiquement toute la hauteur de l'envoi. Une fois que l'envoi est complètement engagé entre les deux roues opposées de l'étage d'entrée, il est entraîné (avec une certaine accélération) par friction vers les roues du second étage et ainsi de suite jusqu'à la sortie du synchronisateur.When a consignment is inserted on edge between the wheels in opposition of the input stage, its front edge deforms the treads of the wheels in opposition substantially on the contact line of the treads. By fading, the treads of opposing wheels exert on the opposite surfaces of the sending a pinch force which is spread over substantially the entire height of the consignment. Once the consignment is fully engaged between the two opposite wheels of the input stage, it is driven (with some acceleration) by friction towards the wheels of the second stage and so on until the output of the synchronizer .
On a constaté que pour les envois les plus épais où la déformation des bandes de roulement est la plus importante, le temps d'insertion de ces envois entre les roues de l'étage d'entrée est également plus important que pour celui des envois plus fins ce qui fait que ces envois épais prennent plus de temps à franchir le synchronisateur que les envois plus fins. Du fait que l'écart entre deux envois consécutifs doit être constant (ou être égal à un multiple de cette valeur d'écart constant), on a constaté que le synchronisateur tel que décrit plus haut était amené à retarder l'instant d'injection de certains envois les plus épais, par exemple en doublant ou en triplant l'écart qui les sépare respectivement des envois les précédant. Ceci a pour conséquence d'affecter le débit de la machine de tri postal.It has been found that for the thickest shipments where the deformation of the treads is the largest, the insertion time of these shipments between the wheels of the entry stage is also greater than for that of the shipments more so that these thick mailings take longer to cross the synchronizer than the finer shipments. Since the difference between two consecutive shipments must be constant (or be equal to a multiple of this constant difference value), it has been found that the synchronizer as described above was required to delay the moment of injection. some of the thickest shipments, for example by doubling or tripling the gap separating them respectively from the items preceding them. This has the effect of affecting the rate of the postal sorting machine.
Le but de l'invention est de pallier cet inconvénient.The object of the invention is to overcome this disadvantage.
A cet effet, l'invention a pour objet un dispositif de convoyage sur chant d'objets plats comprenant deux axes, sur chacun desquels sont disposées, en opposition et de façon symétrique, au moins deux roues à bande de roulement élastiquement déformable de manière à déplacer un objet plat sur chant par pincement et friction, caractérisé en ce que les deux roues sont agencées de telle sorte à exercer un effort de pincement sur l'objet plat sur chant qui est progressif dans le sens de la hauteur à mesure que l'objet plat est entraîné en déplacement.For this purpose, the subject of the invention is a conveying device on edge of flat objects comprising two axes, on each of which are arranged, in opposition and in a symmetrical manner, at least two wheels with an elastically deformable tread so as to move a flat object on singing by pinching and friction, characterized in that the two wheels are arranged so as to exert a pinching force on the flat object on edge which is progressive in the direction of the height as the flat object is driven into displacement.
Cet effort de pincement progressif peut être obtenu selon l'invention, en agençant les roues de manière à ménager entre les bandes de roulement un intervalle de pincement sensiblement en forme de V. Pour cela, les roues en opposition peuvent être montées sur des axes inclinés de 5 à 10°.This progressive clamping effort can be obtained according to the invention, by arranging the wheels so as to arrange between the treads a substantially V-shaped clamping gap. For this, the opposing wheels can be mounted on inclined axes. from 5 to 10 °.
On peut aussi agencer les roues de manière à ménager entre les bandes de roulement un intervalle de pincement sensiblement en forme d'escalier. Pour cela, selon l'invention, chaque bande de roulement est formée en plusieurs anneaux de diamètres différents. On a donc plusieurs bandes de roulement superposées qui peuvent ou non faire partie d'autant de roues différentes superposées. On peut envisager de mettre entre les roues adjacentes une entretoise pour les désolidariser ou au contraire de les superposer sans entretoise et en plus de les rigidifier avec des tiges axiales réparties à la périphérie du moyeu des roues pour limiter le phénomène de flottement des bandes de roulement quand les roues tournent à grande vitesse.The wheels can also be arranged so as to provide between the treads a substantially stair-shaped nip. For this, according to the invention, each tread is formed in several rings of different diameters. There are therefore several superimposed treads that may or may not be part of as many different wheels superimposed. It is conceivable to put between the adjacent wheels a spacer to separate them or on the contrary to superimpose them without spacer and in addition to stiffen them with axial rods distributed around the periphery of the wheel hub to limit the phenomenon of floating of the treads when the wheels are spinning at high speed.
Ces deux configurations des roues en opposition contribuent à obtenir un temps d'insertion des envois de forte épaisseur entre les roues de l'étage d'entrée du synchronisateur quasiment identique à celui des envois de plus faible épaisseur.These two configurations of opposing wheels contribute to obtain a time of insertion of the thick shipments between the wheels of the input stage of the synchronizer almost identical to that of the smaller thicknesses.
L'invention peut s'appliquer à un convoyeur-synchronisateur dans lequel on a des roues en opposition sur un ou plusieurs niveaux superposés comme pour le convoyeur synchronisateur décrit dans le brevet EP-1194249.The invention can be applied to a conveyor-synchronizer in which there are wheels in opposition on one or more superimposed levels as for the synchronizing conveyor described in patent EP-1194249.
Bien entendu, le principe de l'invention peut s'appliquer à tout convoyeur à roues « déformable élastiquement » adapté pour le déplacement d'objets plats par pincement et friction. Le dispositif de convoyage selon l'invention est décrit ci-après en relation avec le dessin.Of course, the principle of the invention can be applied to any wheel conveyor "elastically deformable" adapted for moving flat objects by pinching and friction. The conveying device according to the invention is described below in connection with the drawing.
La figure 1 illustre une configuration de roues avec un intervalle de pincement sensiblement en forme d'escalier.Figure 1 illustrates a wheel configuration with a substantially stair-shaped nip interval.
La figure 2 illustre une configuration de roues avec un intervalle de pincement sensiblement en forme de V.Figure 2 illustrates a wheel configuration with a substantially V-shaped nip.
Sur la figure 1 , on a illustré des roues élastiquement déformables montées en opposition sur deux axes A1 ,A2 parallèles ainsi qu'un objet plat qui se présente sur chant, par exemple un envoi postal plat 1.FIG. 1 illustrates elastically deformable wheels mounted in opposition on two parallel axes A1, A2 and a flat object which is on edge, for example a flat postal item 1.
Les deux axes A1 ,A2 sont montés rotatifs sur une platine 2 qui constitue la sole d'un convoyeur pouvant faire partie d'un dispositif de dépilage d'envois postaux dans une machine de tri postal.The two axes A1, A2 are rotatably mounted on a plate 2 which is the sole of a conveyor that can be part of a device for unstacking postal items in a postal sorting machine.
Comme visible sur la figure 1 , on représenté deux niveaux N1 et N2 de roues motorisées en opposition. R1 désigne des premières roues élastiquement déformables dont la bande de roulement a un diamètre par exemple d'environ 150 mm. R2 désigne des secondes roues élastiquement déformables dont la bande de roulement à un diamètre d'environ 140 mm. R3 désigne des troisièmes roues élastiquement déformables dont la bande de roulement à un diamètre d'environ 130mm.As shown in Figure 1, there is shown two levels N1 and N2 of motorized wheels in opposition. R1 denotes first elastically deformable wheels whose tread has a diameter for example of about 150 mm. R2 denotes second elastically deformable wheels whose tread has a diameter of about 140 mm. R3 denotes third elastically deformable wheels whose tread has a diameter of about 130mm.
Ces roues R1 ,R2 et R3 sont disposées en opposition et de façon symétrique sur les deux axes A1 et A2. Pour le niveau N1 , on a ainsi la superposition (en allant du bas vers le haut) de R1 ,R2,R3 et R2. Pour le niveau N2, on a la superposition R2,R1. Sur les deux niveaux N1 et N2, les roues définissent donc un intervalle de pincement en forme d'escalier dans le sens de la hauteur.These wheels R1, R2 and R3 are arranged in opposition and symmetrically on the two axes A1 and A2. For the level N1, there is thus the superposition (going from the bottom to the top) of R1, R2, R3 and R2. For the level N2, we have the superposition R2, R1. On the two levels N1 and N2, the wheels therefore define a stair-shaped pinching gap in the direction of the height.
En s'insérant (selon une direction perpendiculaire au plan de la feuille) entre les roues en opposition, l'envoi 1 est d'abord pincé entre les roues R1 en opposition qui s'effacent de part et d'autre de l'envoi, puis ensuite entre les roues R2 de plus petit diamètre que les roues R1 et enfin entre les rouesBy inserting (in a direction perpendicular to the plane of the sheet) between the wheels in opposition, the sending 1 is first pinched between the wheels R1 in opposition which disappear on both sides of the sending , then between the wheels R2 of smaller diameter than the wheels R1 and finally between the wheels
R3 de plus petit diamètre que les roues R2. Donc l'effort total de pincement qui s'exerce sur les faces de l'envoi est progressif dans le temps à mesure que l'envoi pénètre entre les roues en opposition de différents diamètres.R3 smaller in diameter than R2 wheels. So the total pinch force exerted on the faces of the shipment is progressive over time as the shipment enters between the wheels in opposition of different diameters.
Dans le cas d'exemple du tri postal, chaque roue a une bande de roulement d'une hauteur de 15 mm qui est reliée à un moyeu par des ailettes souples inclinées. On peut envisager que les roues R1 ,R2,R3 aient des niveaux de dureté (à la déformation) différentes ou que les roues sur un axe aient un même niveau de dureté mais lequel est différent de celui des roues situées sur l'autre axe.In the case of postal sorting example, each wheel has a tread of a height of 15 mm which is connected to a hub by inclined flexible fins. It is conceivable that the wheels R1, R2, R3 have different levels of hardness (at deformation) or that the wheels on one axis have the same level of hardness but which is different from that of the wheels located on the other axis.
Sur la figure 2, on a illustré une configuration des roues selon laquelle les bandes de roulement définissent un intervalle de pincement en forme de V. Ici les axes A' sont disposés de façon inclinée l'un par rapport à l'autre sur la platine 2' et portent chacun deux niveaux NV et N2' de roues R. Les roues R ont ici un diamètre identique.FIG. 2 illustrates a configuration of the wheels in which the treads define a V-shaped nip. Here the axes A 'are inclined with respect to one another on the plate. 2 'and each carry two levels NV and N2' of wheels R. The wheels R here have an identical diameter.
Quand l'envoi V s'avance (perpendiculairement au plan de la feuille) entre les deux axes inclinés, son bord avant est progressivement pincé, à mesure qu'il s'avance, entre les bandes de roulement des roues R du niveau N2' (niveau le plus inférieur) puis entre les bandes de roulement des roues R du niveau NV (on a représenté par les lignes E, les points de contact entre l'envoi et les roues R).When the sending V advances (perpendicularly to the plane of the sheet) between the two inclined axes, its front edge is progressively pinched, as it moves forward, between the treads of the wheels R of the level N2 ' (lowest level) and then between the treads of the wheels R level NV (it is represented by the lines E, the points of contact between the consignment and the wheels R).
On peut bien entendu combiner à la fois des axes inclinés comme représenté sur la figure 2 avec des roues de diamètres différents comme représenté sur la figure 1 sans sortir du cadre de l'invention. It is of course possible to combine both inclined axes as shown in FIG. 2 with wheels of different diameters as shown in FIG. 1 without departing from the scope of the invention.
