Domaine techniqueTechnical area

L'invention concerne une machine de tri postal comprenant un dépileur dans une entrée d'alimentation en articles de courrier, un convoyeur de tri conçu pour mettre en série sur chant les articles de courrier dépilés de l'entrée d'alimentation et des sorties de tri comprenant chacune un réceptacle conçu pour stocker en pile sur chant les articles de courrier provenant dudit convoyeur de tri.The invention relates to a postal sorting machine comprising a destacker in a feed inlet for mail items, a sorting conveyor designed to serially edge the mail items unstacked from the feed inlet and outlets. sorting each comprising a receptacle designed to store in a pile on edge the mail items coming from said sorting conveyor.

Technique antérieurePrior art

Les tasseurs de type roue à hélice sont fréquemment utilisés dans les machines de tri postal pour permettre la formation des piles d'articles de courrier dans les réceptacles des sorties de tri, comme décrit dans le document JPH0899755 A .Propeller-type packers are frequently used in postal sorting machines to allow the formation of stacks of mail items in the receptacles of sorting outlets, as described in the document. JPH0899755 A .

L'hélice de la roue d'un tasseur fait généralement saillie par une ouverture dans le fond du réceptacle de sortie de tri et permet de pousser le pied d'un article de courrier courant contre la pile d'articles de courrier en formation.The propeller of the wheel of a packer generally projects through an opening in the bottom of the sorting outlet receptacle and makes it possible to push the foot of a current mail item against the stack of mail items being formed.

La roue est mise en rotation par un arbre de transmission à courroie motorisée disposé sous le réceptacle.The wheel is rotated by a motorized belt drive shaft disposed under the receptacle.

Durant la phase de tri des articles de courrier en machine, le mouvement en rotation de la roue est continu afin de rabattre machinalement les articles de courrier dès leur arrivée dans la sortie de tri.During the sorting phase of mail items in a machine, the rotary movement of the wheel is continuous in order to mechanically fold down the mail items as soon as they arrive in the sorting outlet.

plastique car elles limitent la détérioration des articles de courrier en cours d'empilage dans les sorties de tri.plastic because they limit the deterioration of mail items being stacked in sorting outlets.

Les opérateurs des services de maintenance ont cependant constaté que les frottements exercés sur les roues par les articles de courrier la plupart en papier, matière connue pour être abrasive, provoquent une usure rapide des hélices en plastique.Maintenance service operators have however noted that the friction exerted on the wheels by mail items, most of which are made of paper, a material known to be abrasive, cause rapid wear of the plastic propellers.

Une hélice en mauvaise état crée des bourrages au niveau de la sortie de tri et un empilage de mauvaise qualité.A propeller in poor condition creates jams at the sorting outlet and poor quality stacking.

Cette usure fréquente de l'hélice requiert le remplacement rapide de la roue usée par le service de maintenance.This frequent wear of the propeller requires rapid replacement of the worn wheel by the maintenance department.

Or, la roue à hélice est difficile d'accès puisqu'il faut démonter au préalable au moins le réceptacle de la sortie de tri, l'arbre de transmission et sa courroie.However, the propeller wheel is difficult to access since it is necessary to disassemble at least the receptacle for the sorting outlet, the transmission shaft and its belt.

Cette maintenance nécessite donc un arrêt complet de la machine de tri sur une longue période de temps.This maintenance therefore requires a complete shutdown of the sorting machine over a long period of time.

Actuellement, cette perte d'exploitation de la machine est plus dommageable que la mauvaise qualité d'empilage.Currently, this loss of machine operation is more damaging than the poor quality of stacking.

C'est la raison pour laquelle le service de maintenance préfère attendre l'usure de toutes les roues des sorties de tri ou d'autres pièces disposées sous le réceptacle avant de procéder à l'arrêt complet de la machine de tri, au risque d'avoir un empilage de mauvaise qualité.This is the reason why the maintenance department prefers to wait for the wear of all the wheels of the sorting outlets or other parts placed under the receptacle before proceeding with the complete stopping of the sorting machine, at the risk of '' have poor quality stacking.

Le document WO 2013/046862 A1 divulgue une roue montée sur un arbre de transmission au moyen d'un clipsage selon un mouvement en translation transversale par rapport à l'axe de rotation de l'arbre de transmission.The document WO 2013/046862 A1 discloses a wheel mounted on a drive shaft by means of a clipping in a movement in transverse translation relative to the axis of rotation of the drive shaft.

Exposé de l'inventionStatement of the invention

Le but de l'invention est donc de remédier à ces inconvénients.The object of the invention is therefore to remedy these drawbacks.

A cet effet, l'invention a donc pour objet une machine de tri postal comprenant un dépileur dans une entrée d'alimentation en articles de courrier, un convoyeur de tri conçu pour mettre en série sur chant les articles de courrier dépilés de l'entrée d'alimentation et des sorties de tri comprenant chacune un réceptacle conçu pour stocker en pile sur chant les articles de courrier provenant dudit convoyeur de tri, chaque sortie de tri comprenant une roue à hélice qui fait saillie par une ouverture dans le fond du réceptacle, ladite roue étant montée sur un arbre de transmission disposé sous le réceptacle pour donner un mouvement en rotation à l'hélice de sorte à ce que l'hélice pousse le pied d'un article de courrier courant dans le réceptacle contre la pile d'articles de courrier en formation, caractérisée en ce que la roue est montée sur l'arbre de transmission au moyen d'un clipsage selon un mouvement en translation transversale par rapport à l'axe de rotation de l'arbre de transmission.To this end, the subject of the invention is therefore a postal sorting machine comprising a destacker in an inlet for supplying mail items, a sorting conveyor designed to serially place the mail items unstacked from the inlet feed and sorting outlets each comprising a receptacle designed to store in a pile on edge the mail items coming from said sorting conveyor, each sorting outlet comprising a propeller wheel which projects through an opening in the bottom of the receptacle, said wheel being mounted on a drive shaft disposed under the receptacle to give a rotation movement to the propeller so that the propeller pushes the foot of a mail item running in the receptacle against the stack of items of mail in formation, characterized in that the wheel is mounted on the transmission shaft by means of a clipping according to a movement in transverse translation relative to the axis of rotation of the drive shaft.

L'idée à la base de l'invention consiste à ne plus démonter le réceptacle ni l'arbre de transmission pour changer la roue à hélice. L'idée est également de permettre au service de maintenance de changer la roue dans une position de travail ergonomique.The idea underlying the invention consists in no longer dismantling the receptacle or the transmission shaft to change the propeller wheel. The idea is also to allow the maintenance service to change the wheel in an ergonomic working position.

Pour cela la roue à hélice selon l'invention est ici montable/démontable dans la sortie de tri à travers l'ouverture du réceptacle où sont empilés les articles de courrier. Le mouvement en translation transversale de la roue par rapport à l'axe de rotation de l'arbre permet lors de son démontage de l'extraire facilement par l'ouverture du réceptacle et lors de son montage de l'insérer à travers l'ouverture puis de la clipser à l'arbre de transmission. On comprendra que le service de maintenance pourra changer fréquemment les roues sans démonter les sorties de tri, simplement en se positionnant à proximité des sorties de tri pour atteindre à bout de bras l'ouverture dans le fond du réceptacle.For this the propeller wheel according to the invention is here mountable / dismountable in the sorting outlet through the opening of the receptacle where the mail items are stacked. The movement in transverse translation of the wheel relative to the axis of rotation of the shaft allows when it is disassembled to extract it easily through the opening of the receptacle and during its assembly to insert it through the opening then clip it to the drive shaft. It will be understood that the maintenance service can frequently change the wheels without dismantling the sorting outlets, simply by positioning themselves near the sorting outlets to reach at arm's length the opening in the bottom of the receptacle.

Le gain de temps permet ici non seulement de changer fréquemment les roues pour garantir un bon empilage dans les sorties de tri mais également de réduire les temps de maintenance et d'arrêt de la machine.The time savings here not only frequently change the wheels to ensure good stacking in sorting outlets, but also reduce machine maintenance and downtime.

La machine de tri selon l'invention peut également présenter les particularités suivantes :

  • la roue peut comprendre une jante pourvue d'un trou agencé pour permettre le déclipsage du moyen de clipsage par l'ouverture dans le fond du réceptacle ;
  • la roue et l'arbre de transmission peuvent comprendre des moyens de guidage pour réaliser le mouvement en translation transversale de la roue par rapport à l'axe de rotation de l'arbre. Le mouvement en translation transversale de la roue par rapport à l'axe de rotation de l'arbre permet à la roue d'aller se positionner correctement sur l'arbre, afin d'avoir les axes de rotation de la roue et de l'arbre de transmission confondus et de faciliter le clipsage par un guidage durant toute la translation.
  • les moyens de guidage peuvent être formés par une rainure qui s'étend transversalement par rapport à l'axe de rotation de la roue et par un tenon qui s'étend à une des extrémités de l'arbre de transmission transversalement à son axe de rotation et qui est adapté pour se déplacer dans la rainure.
The sorting machine according to the invention can also have the following particularities:
  • the wheel may comprise a rim provided with a hole arranged to allow the unclipping of the clipping means by the opening in the bottom of the receptacle;
  • the wheel and the transmission shaft may comprise guide means for carrying out the movement in transverse translation of the wheel with respect to the axis of rotation of the shaft. The movement in transverse translation of the wheel relative to the axis of rotation of the shaft allows the wheel to position itself correctly on the shaft, in order to have the axes of rotation of the wheel and the drive shaft combined and to facilitate clipping by guiding throughout the translation.
  • the guide means can be formed by a groove which extends transversely to the axis of rotation of the wheel and by a lug which extends at one end of the drive shaft transversely to its axis of rotation and which is adapted to move in the groove.

La mise en rotation de l'arbre de transmission 13 est donnée par un jeu de courroies 14 entrainées en continue par un moteur.As shown in the figure 3 , the wheel 11 is here mounted on a motorized transmission shaft 13 disposed under the support 7. The rotation of the transmission shaft 13 is given by a set of belts 14 continuously driven by a motor.

L'intégralité du système de mise en rotation est disposée sous le support 7 et seule l'hélice 12 de la roue 11 fait saillie par l'ouverture dans le fond du support 7, comme représenté sur la figure 2 et 3. La roue 11 quant à elle vient à fleur dans le fond du réceptacle de sorte à boucher au maximum l'ouverture.The entire rotation system is disposed under the support 7 and only the propeller 12 of the wheel 11 projects through the opening in the bottom of the support 7, as shown in the figure 2 and 3 . As for the wheel 11, it comes flush with the bottom of the receptacle so as to block the opening as much as possible.

Comme représenté sur les figures 3 et 4, l'hélice 12 s'étend de préférence autour de la jante 15 de la roue 11 d'un bord à un autre de sorte à effectuer un tour complet de la jante 15 de la roue.As shown on figures 3 and 4 , the propeller 12 preferably extends around the rim 15 of the wheel 11 from one edge to another so as to make a complete revolution of the rim 15 of the wheel.

La rotation de l'hélice 12 permet de pousser le pied d'un article de courrier 2 courant dans le réceptacle suivant ladite direction longitudinale D1 contre la pile d'articles de courrier en formation.The rotation of the propeller 12 makes it possible to push the foot of a mail item 2 running in the receptacle in said longitudinal direction D1 against the stack of mail items being formed.

Pour augmenter la prise rapide d'un article de courrier courant, chaque roue peut comprendre plusieurs hélices 12 sensiblement parallèles les unes avec les autres sur la jante 15, ici trois segments comme visible sur les figures 3, 4 et 6.To increase the rapid take-up of a current mail item, each wheel may include several propellers 12 substantially parallel with each other on the rim 15, here three segments as visible on the figures 3, 4 and 6 .

Par ailleurs, un moyen de clipsage rapide est également prévu pour fixer la roue 11 à l'arbre de transmission. Pour cela, la roue comprend une languette 16 déformable et l'arbre de transmission une butée 17 à l'extrémité par laquelle la roue est fixée. La languette étant conçue pour se déformer sur la butée puis venir se loger derrière la butée pour bloquer la roue avec l'arbre de transmission, comme visible sur les figures 6 et 7. Le clipsage est effectué selon un mouvement en translation transversale par rapport à l'axe de rotation A1 de l'arbre de transmission représenté par la flèche D2 sur la figure 6.Furthermore, a quick clip-on means is also provided for fixing the wheel 11 to the drive shaft. For this, the wheel comprises a deformable tongue 16 and the transmission shaft a stop 17 at the end by which the wheel is fixed. The tongue being designed to deform on the stop then come to be housed behind the stop to block the wheel with the drive shaft, as visible on the Figures 6 and 7 . Clipping is carried out in a transverse translational movement relative to the axis of rotation A1 of the drive shaft represented by the arrow D2 on the figure 6 .

Afin de faciliter le montage du tasseur dans la sortie de tri, la roue 11 et l'arbre de transmission 13 comprennent des moyens de guidage pour le mouvement en translation transversale de la roue par rapport à l'axe de rotation de l'arbre.In order to facilitate the mounting of the packer in the sorting outlet, the wheel 11 and the transmission shaft 13 comprise guide means for the movement in transverse translation of the wheel relative to the axis of rotation of the shaft.

Ces moyens de guidage, représentés sur les figures 6 et 7, sont formés ici par une rainure 18 qui s'étend dans la roue transversalement par rapport à l'axe de rotation de la roue A2 et par un tenon 19 qui s'étend à une des extrémités de l'arbre de transmission transversalement à son axe de rotation, comme visible sur la figure 4.These guide means, represented on the Figures 6 and 7 , are formed here by a groove 18 which extends in the wheel transversely relative to the axis of rotation of the wheel A2 and by a lug 19 which extends at one end of the transmission shaft transversely to its axis of rotation, as visible on the figure 4 .

On comprendra que le tenon 19 est adapté pour se déplacer dans la rainure 18 selon le mouvement en translation transversale représenté par la flèche D2.It will be understood that the post 19 is adapted to move in the groove 18 according to the movement in transverse translation represented by the arrow D2.

On comprendra également que la butée 17 est placée sur le tenon 19.It will also be understood that the stop 17 is placed on the post 19.

La jante 15 de la roue 11 comprend également un trou 20, visible sur les figures 5, 6 et 7, accessible depuis l'ouverture dans le fond du réceptacle pour permettre le déclipsage des moyens de clipsage.The rim 15 of the wheel 11 also includes a hole 20, visible on the figures 5 , 6 and 7 , accessible from the opening in the bottom of the receptacle to allow the unclipping of the clipping means.

Plus particulièrement ce trou 20 donne accès à la languette 16 déformable au moyen d'un outil fin, par exemple un tournevis, afin d'exercer une pression sur elle et par effet de levier, de la déloger de la butée 17 du tenon 19.More particularly, this hole 20 gives access to the tongue 16 deformable by means of a fine tool, for example a screwdriver, in order to exert pressure on it and, by leverage, to dislodge it from the stop 17 of the lug 19.

On comprendra que le trou 20 sert également de repère visuel pour un opérateur des services de maintenance qui souhaite placer la roue dans une position adéquate pour déloger la languette 16 de la butée 17.It will be understood that the hole 20 also serves as a visual cue for an operator of the maintenance services who wishes to place the wheel in an adequate position to dislodge the tongue 16 from the stop 17.

Pour changer une roue usée, un opérateur doit donc dans un premier temps tourner la roue usée jusqu'à présenter le trou 20 visible à travers l'ouverture dans le support 7. L'opérateur engage ensuite un tournevis dans le trou jusqu'à atteindre la languette 16 et fait pression sur elle pour la déloger de la butée 17. L'Opérateur retire ensuite la roue 11 à travers l'ouverture dans le support 7 en effectuant un mouvement en translation transversale par rapport à l'axe de rotation A1 de l'arbre de transmission 13.To change a worn wheel, an operator must therefore first turn the worn wheel until the hole 20 is visible through the opening in the support 7. The operator then engages a screwdriver in the hole until it reaches the tongue 16 and presses on it to dislodge it from the stop 17. The operator then removes the wheel 11 through the opening in the support 7 by carrying out a movement in transverse translation relative to the axis of rotation A1 of the drive shaft 13.

Pour insérer une nouvelle roue 11, l'Opérateur doit dans un premier temps insérer la roue 11 à travers l'ouverture dans le support 7 en effectuant un mouvement en translation transversale par rapport à l'axe de rotation A1 de l'arbre de transmission 13.To insert a new wheel 11, the Operator must first insert the wheel 11 through the opening in the support 7 by carrying out a movement in transverse translation relative to the axis of rotation A1 of the drive shaft 13.

Puis, lorsque la languette 16 atteint la butée 17, l'Opérateur effectue un effort de pression supplémentaire sur la roue 11 en translation transversale par rapport à l'axe de rotation A1 de l'arbre de transmission 13 afin de loger la languette 16 derrière la butée pour fixer la roue 11 à l'arbre de transmission 13.Then, when the tongue 16 reaches the stop 17, the Operator applies an additional pressure force on the wheel 11 in transverse translation relative to the axis of rotation A1 of the drive shaft 13 in order to accommodate the tongue 16 behind the stopper for fixing the wheel 11 to the drive shaft 13.
