Description

Domaine techniqueTechnical area

Le domaine de l'invention est celui des convoyeurs de transport à bandes de pincement.The field of the invention is that of transport conveyors pinch strips.

L'invention concerne plus particulièrement un procédé de réglage pour régler en hauteur des courroies ou bandes de pincement dans un convoyeur de transport qui déplacent des articles plats en série sur chant, en vue d'obtenir une hauteur de vol sensiblement constante des articles plats lorsqu'ils sont déplacés par les bandes de pincement dans le convoyeur.The invention relates more particularly to an adjustment method for adjusting in height belts or nipping webs in a transport conveyor which move flat articles in series on edge, in order to obtain a substantially constant flight height of the flat articles when they are moved by the pinch strips in the conveyor.

Technique antérieurePrior art

Les convoyeurs de transport à bandes de pincement sont très répandus dans le tri postal pour trier des articles de courrier plats comme des lettres.Pinch transport conveyors are widely used in postal sorting to sort flat mail items such as letters.

Ces convoyeurs sont aussi appelés convoyeurs de tri et comportent un grand nombre de sorties de tri.These conveyors are also called sorting conveyors and have a large number of sorting outlets.

Ils sont conçus le plus souvent de façon modulaire avec plusieurs modules contigus comportant chacun plusieurs sorties de tri.They are most often designed in a modular way with several contiguous modules each having several sorting outlets.

Les sorties de tri sont matérialisées par autant de bandes de pincement différentes qui sont orientées de façon transversale par rapport à une bande de pincement principale qui s'étend sur la grande longueur du module.The sorting outlets are materialized by as many different gripping strips which are oriented transversely with respect to a main gripping band which extends over the great length of the module.

Il est extrêmement important dans ces convoyeurs de tri postal que les courriers soient déplacés d'un module à un autre et au sein d'un même module en restant toujours bien horizontaux sur chant et à une même hauteur par rapport à la sole du convoyeur de transport sinon ils risquent de se cambrer et d'entraîner des bourrages dans le convoyeur.It is extremely important in these postal sorting conveyors that the mails are moved from one module to another and within the same module while always remaining horizontal on edge and at the same height with respect to the conveyor sole of the conveyor. transport otherwise they may arch and cause jams in the conveyor.

C'est pourquoi il est nécessaire de régler et contrôler régulièrement la hauteur de vol des courriers (distance entre le bord inférieur du courrier et la sole) dans ces convoyeurs de tri postal en agissant sur le positionnement en hauteur des bandes de pincement.That is why it is necessary to regulate and regularly check the flight height of the mails (distance between the lower edge of the mail and the sole) in these postal sorting conveyors by acting on the positioning in height of the clamping bands.

Le contrôle de la hauteur de vol des courriers se fait jusqu'à présent de la façon suivante.The control of the flight height of the mails is done so far in the following way.

Le convoyeur est chargé avec des courriers puis est arrêté.The conveyor is loaded with couriers and then stopped.

Un Opérateur mesure le long des bandes de pincement à l'arrêt la hauteur de vol des courriers tenus par ces bandes. Si la hauteur de vol est variable d'un module à un autre, l'Opérateur manipule des tendeurs de bande pour compenser les différences de hauteur puis remet en route et arrête de nouveau le convoyeur pour refaire les mesures de hauteur de vol.An Operator measures along the pinch strips at the stop the flight height of the couriers held by these bands. If the flight height is variable from one module to another, the Operator manipulates tape tensioners to compensate for the differences in height and then restarts and stops the conveyor again to redo the flight height measurements.

Comme il y a un grand nombre de bandes de pincement (ou courroies) dans un tel convoyeur, cette opération de réglage et de contrôle est fastidieuse.Since there are a large number of nips (or belts) in such a conveyor, this adjustment and control operation is tedious.

Un procédé de réglage de la hauteur des courroies est par exemple décrit dans le document US2009/133992 .A method of adjusting the height of the belts is for example described in the document US2009 / 133992 .

Résumé de l'inventionSummary of the invention

Le but de l'invention est de proposer un procédé de réglage pour régler la hauteur de vol d'articles plats dans un convoyeur de transport à bandes de pincement qui apporte une très grande précision de réglage et aussi qui est facile et rapide à mettre en oeuvre permettant le réglage par un Opérateur non technicien.The object of the invention is to propose a control method for adjusting the flight height of flat articles in a transport conveyor with pinch strips which provides a very high accuracy of adjustment and also which is easy and quick to implement. allowing adjustment by a non-technical Operator.

A cet effet, l'invention a pour objet un procédé de réglage pour régler en hauteur des courroies ou bandes de pincement dans un convoyeur de transport qui déplacent des articles plats en série sur chant, en vue d'obtenir une hauteur de vol sensiblement constante des articles plats lorsqu'ils sont déplacés par les bandes de pincement dans le convoyeur, caractérisé en ce qu'il comprend les étapes suivantes :

  • faire fonctionner le convoyeur à vide de telle sorte que les bandes de pincement à régler en hauteur tournent sans aucun article plat dans le convoyeur,
  • émettre en direction d'une bande à régler en hauteur deux faisceaux lumineux parallèles et superposés qui sont écartés l'un de l'autre d'une certaine distance égale à la largeur de la bande entre les deux bords opposés de la bande à régler en hauteur, ces deux signaux lumineux étant émis depuis un boitier ayant un socle calibré en hauteur à savoir que les deux faisceaux lumineux sont disposés par rapport au socle du boitier à une certaine hauteur calibrée pour correspondre à ladite hauteur de vol des articles plats dans le convoyeur,
  • et manipuler un tendeur sur lequel est engagée la bande de pincement à régler pour déplacer en hauteur ladite bande à régler pendant qu'elle tourne à vide jusqu'à ce que les deux faisceaux lumineux croisent respectivement les deux bords opposés de la bande.
To this end, the subject of the invention is an adjustment method for adjusting in height belts or pinch strips in a transport conveyor which move flat articles in series on edge, in order to obtain a substantially constant flight height of the flat articles when they are moved by the gripping strips in the conveyor, characterized in that it comprises the following steps:
  • operating the vacuum conveyor so that the pinch strips to be adjusted in height rotate without any flat article in the conveyor,
  • transmitting, in the direction of a band to be adjusted in height, two parallel and superimposed light beams which are separated from each other by a certain distance equal to the width of the band between the two opposite edges of the band to be adjusted in height, these two light signals being emitted from a housing having a base calibrated in height, namely that the two light beams are arranged relative to the base of the housing at a certain height calibrated to correspond to said flying height of the flat articles in the conveyor ,
  • and manipulating a tensioner on which is engaged the clamping band to be adjusted to move up said band to be adjusted while it rotates empty until the two light beams respectively cross the two opposite edges of the band.

Le procédé selon l'invention peut encore présenter les particularités suivantes :

  • on émet des faisceaux lumineux à section circulaire ce qui fait que lorsqu'ils croisent les deux bords opposés de la bande, on observe deux tâches semi-circulaires sur les deux bords opposés de la bande ce qui est facilement identifiable par un Opérateur non technicien,
  • le boîtier est un outillage portatif qui est muni d'une batterie qui alimente des LEDs produisant les deux faisceaux lumineux,
  • le socle du boîtier peut être aimanté ce qui facilite sa fixation sur la platine du convoyeur pendant le réglage,
  • le boîtier peut être muni d'un miroir orientable ce qui facilite et permet à l'Opérateur de manipuler le tendeur tout en observant à distance dans le miroir une image des deux faisceaux lumineux qui croisent la bande.
The process according to the invention may also have the following features:
  • light beams of circular section are emitted so that when they cross the two opposite edges of the strip, there are two semi-circular spots on the two opposite edges of the strip which is easily identifiable by a non-technical operator,
  • the housing is a portable tool which is provided with a battery which supplies LEDs producing the two light beams,
  • the base of the housing can be magnetized which facilitates its attachment to the conveyor plate during adjustment,
  • the housing can be provided with a steerable mirror which facilitates and allows the operator to manipulate the tensioner while observing at a distance in the mirror an image of the two light beams crossing the band.

Un exemple de mise en oeuvre du procédé de réglage selon l'invention est décrit ci-après et illustré par les dessins.An exemplary implementation of the adjustment method according to the invention is described below and illustrated by the drawings.

Présentation sommaire des dessinsBrief presentation of the drawings

La figure 1 illustre de façon très schématique un convoyeur de tri postal modulaire.The figure 1 Very schematically illustrates a modular postal sorting conveyor.

La figure 2 illustre de façon très schématique un exemple d'un outillage émetteur de faisceaux lumineux pour la mise en oeuvre du procédé dans le convoyeur de tri illustré sur la figure 1.The figure 2 illustrates very schematically an example of a light beam emitting tool for the implementation of the method in the sorting conveyor illustrated in FIG. figure 1 .

Description des modes de réalisationDescription of the embodiments

Sur la figure 1, on a illustré ici à titre d'exemple de façon très schématique un convoyeur de transport 1 pour le tri postal d'articles de courrier plats constitué de plusieurs modules de tri 2 adjacents.On the figure 1 a transport conveyor 1 for the postal sorting of flat mail articles consisting of several adjacent sorting modules 2 has been illustrated by way of example in a very schematic manner.

Un module de tri 2 comporte ici plusieurs sorties de tri indiquées par la référence 3 alignées sur la grande longueur du module suivant la flèche F.A sorting module 2 here comprises several sorting outlets indicated by the reference 3 aligned on the long length of the module according to the arrow F.

Un convoyeur de tri tel que 1 peut comprendre un grand nombre de modules de tri 2 et donc de sorties de tri 3.A sorting conveyor such as 1 may include a a large number of sorting modules 2 and thus sorting outlets 3.

On a illustré dans le module de tri des courriers A qui sont déplacés par des bandes de pincement en boucle fermée ou courroies à l'intérieur du module 2.In the sorting module, couriers A have been shown which are moved by closed-loop nipping straps or belts inside the module 2.

Ici les bandes de pincement comprennent une bande de pincement principale 4 et des bandes de pincement secondaires 5 qui matérialisent les sorties de tri du module.Here the pinch strips comprise a main pinching strip 4 and secondary pinching strips 5 which materialize the sorting outlets of the module.

Comme visible sur la figure 1, un courrier A est pincé à plat sur chant (en mode paysage) entre la bande principale 4 et une bande secondaire telle que 5 lesquelles en tournant le déplacent sur chant au-dessus de la sole du convoyeur (platine).As visible on the figure 1 , a mail A is pinched flat on edge (in landscape mode) between the main band 4 and a secondary band such that 5 by turning it on edge over the sole of the conveyor (platinum).

En réalité le courrier A ne touche pas la sole du convoyeur pendant son déplacement avec les bandes de pincement mais a tendance à s'élever légèrement au-dessus de la sole et on parle alors de "hauteur de vol" pour le courrier A.In reality the mail A does not touch the sole of the conveyor during its movement with the pinch strips but tends to rise slightly above the sole and is then called "flight height" for the mail A.

Toutes ces bandes de pincement 4,5 sont entrainées en mouvement rotatif par des galets motorisés tels que 6 et il est prévu le long du chemin des bandes de pincement un tendeur de bande ici sous la forme d'une poulie orientable à axe de rotation décentré désignée sur la figure 1 par la référence 7.All these clamping strips 4,5 are driven in rotary motion by motorized rollers such as 6 and there is provided along the path of the clamping strips a belt tensioner here in the form of a rotatable pulley with off-axis rotational axis designated on the figure 1 by reference 7.

Ce type de poulie orientable est bien connu de l'Homme du métier. La bande 4 qui est engagée sur une poulie orientable 7 peut être élevée ou abaissée au dessus de la sole 8 du module.This type of steerable pulley is well known to those skilled in the art. The band 4 which is engaged on a steerable pulley 7 can be raised or lowered above the sole 8 of the module.

Le procédé selon l'invention pour régler la hauteur de vol d'articles plats comme du courrier dans un convoyeur de tri tel que 1 sur la figure 1, utilise un outillage de réglage sans contact qui permet de contrôler la position des bandes de pincement en hauteur dans le convoyeur en marche.The method according to the invention for adjusting the flight height of flat articles such as mail in a sorting conveyor such as 1 on the figure 1 , uses a non-contact adjustment tool that allows to control the position of the clamping strips in height in the moving conveyor.

Cet outillage est référencé 9 sur la figure 1 et est illustré plus en détail sur la figure 2.This tool is referenced 9 on the figure 1 and is illustrated in more detail on the figure 2 .

L'outillage 9 est un émetteur qui est apte à produire deux faisceaux lumineux superposés S1, S2 qui sont parallèles et écartés l'un de l'autre d'une distance égale à la largeur D de la bande de pincement à régler en hauteur.The tool 9 is a transmitter which is able to produce two superimposed light beams S1, S2 which are parallel and spaced from each other by a distance equal to the width D of the clamping band to be adjusted in height.

L'émetteur se présente sous forme d'un boîtier portatif 10 dans lequel sont disposées deux LEDs alimentées par une batterie électrique non représentée sur la figure 2.The transmitter is in the form of a portable housing 10 in which are disposed two LEDs powered by an electric battery not shown on the figure 2 .

Le boîtier 10 a un socle 11 qui peut être aimanté pour se fixer de façon détachable sur la platine horizontale 8 du convoyeur de tri formant la sole du convoyeur.The housing 10 has a base 11 which can be magnetized to detachably attach to the horizontal plate 8 of the sorting conveyor forming the sole of the conveyor.

Le socle 11 peut être ajustable en hauteur pour que la hauteur séparant la platine 8 du faisceau S2 indiquée par H sur la figure 2 soit réglable et corresponde à la hauteur de vol h du courrier recherchée.The base 11 may be adjustable in height so that the height separating the plate 8 of the beam S2 indicated by H on the figure 2 is adjustable and corresponds to the flight height h of the mail sought.

Le sommet du boîtier 10 peut être muni d'un miroir 12 orientable qui est par exemple monté rabattable sur le boîtier 10 comme illustré par la double flèche R.The top of the housing 10 may be provided with a steerable mirror 12 which is for example mounted to fold on the housing 10 as illustrated by the double arrow R.

Le procédé selon l'invention de réglage de la hauteur des bandes 4,5 et donc de la hauteur h de vol de courriers tels que A sur la figure 2 dans le module 2 du convoyeur de tri comprend les étapes consistant pour un Opérateur assurant le réglage ou le contrôle à :

  • mettre le convoyeur en marche et le faire fonctionner à vide c'est à dire sans courrier A entre les bandes 4,5 alors que celles-ci tournent,
  • placer l'outillage 9 sur la platine 8 à proximité de la poulie de réglage 7 pour qu'il émette les deux faisceaux lumineux S1 et S2,
  • orienter l'outillage émetteur 9 pour que les deux faisceaux lumineux S1 et S2 croisent si possible à angle droit la bande 4 par exemple qui est à régler en hauteur,
  • manipuler la poulie de réglage inclinée 7 sur laquelle est engagée la bande 4 pour faire descendre ou monter la bande 4, la manipulation de la poulie 7 consistant par exemple à faire tourner dans un sens ou dans l'autre l'axe de rotation incliné de la poulie 7 ce qui engendre l'abaissement ou l'élévation de la bande 4,
  • arrêter le réglage quand les deux faisceaux lumineux S1 et S2 croisent les deux bords opposés de la bande 4, c'est-à-dire que la bande est centrée entre les deux faisceaux lumineux.
The method according to the invention for adjusting the height of the bands 4,5 and thus the height h of theft of couriers such as A on the figure 2 in the sorting conveyor module 2 comprises the steps of an operator providing adjustment or control to:
  • put the conveyor into operation and make it run empty, that is to say without mail A between the bands 4,5 while they are running,
  • placing the tool 9 on the plate 8 near the adjusting pulley 7 so that it emits the two light beams S1 and S2,
  • orienting the transmitter tooling 9 so that the two light beams S1 and S2 cross if possible at right angles the band 4 for example which is to be adjusted in height,
  • manipulate the inclined adjusting pulley 7 on which the band 4 is engaged to lower or mount the band 4, the handling of the pulley 7 consisting for example of rotating in one direction or the other the inclined rotation axis of the pulley 7 which causes the lowering or elevation of the band 4,
  • stopping the setting when the two light beams S1 and S2 cross the two opposite edges of the band 4, that is to say that the band is centered between the two light beams.

Selon l'invention, les deux faisceaux lumineux S1 et S2 sont à section circulaire de sorte que le réglage est parfait quand on observe deux tâches semi-circulaires sur les deux bords opposés de la bande comme illustré sur la figure 2.According to the invention, the two light beams S1 and S2 are circular in section so that the adjustment is perfect when two semicircular spots are observed on the two opposite edges of the strip as illustrated in FIG. figure 2 .

En pratique, dans un convoyeur de tri avec de nombreux modules de tri 2, l'Opérateur doit régler un grand nombre de bandes de pincement avec l'outillage 9 et donc manipuler un certain nombre de poulies inclinées 9 réparties sur le trajet des bandes de pincement.In practice, in a sorting conveyor with many sorting modules 2, the Operator must adjust a large number of gripping strips with the tooling 9 and thus manipulate a number of inclined pulleys 9 distributed over the path of the belts. pinch.

L'Opérateur procède donc au réglage en hauteur de toutes les bandes de pincement du convoyeur en utilisant son outillage portatif 9.The operator then proceeds to the height adjustment of all the conveyor pinch strips using his portable tooling 9.

Par ailleurs, le réglage en hauteur d'une bande de pincement comme la bande 4 doit être fait en général sur deux points distants de cette bande, par exemple à l'entrée et à la sortie du module 2. L'Opérateur doit donc placer l'outillage 9 à l'entrée du module et manipuler la poulie 7 sur laquelle est engagée la bande 4 pour régler la hauteur de la bande en entrée du module. Puis l'Opérateur déplace l'outillage 9 vers la sortie du module et recommence alors la manipulation de la poulie 7 pour régler de nouveau la hauteur de la bande en sortie du module. Le déplacement et le positionnement de l'outillage 9 est facilité si le boitier de l'outillage a un socle aimanté qui se fixe et se détache facilement de la platine du convoyeur qui est en métal.Furthermore, the height adjustment of a pinch band like the band 4 must be done generally at two points distant from this band, for example at the input and at the output of the module 2. The Operator must therefore place the tool 9 at the input of the module and manipulate the pulley 7 on which is engaged the band 4 to adjust the height of the band at the input of the module. Then the operator moves the tool 9 to the output of the module and then starts again the handling of the pulley 7 to adjust the height of the band again at the output of the module. The movement and positioning of the tooling 9 is facilitated if the case of the tooling has a magnetic base which easily attaches and detaches from the conveyor plate which is made of metal.

Si l'espace relatif entre la poulie inclinée 7 manipulée par l'Opérateur et le point de réglage où est placé l'outillage 9 est relativement important ou n'est pas visuellement dégagé, l'Opérateur pourra néanmoins observer à distance dans le miroir 12 l'image des faisceaux lumineux S1 et S2 sur la bande de façon à parvenir à la régler précisément en hauteur la bande de pincement.If the relative space between the inclined pulley 7 manipulated by the operator and the set point where the tooling 9 is placed is relatively large or not visually cleared, the operator can nevertheless observe remotely in the mirror 12 the image of the light beams S1 and S2 on the strip so as to be able to adjust the height of the pinch band precisely.
