Description des modes de réalisationDescription of the embodiments

Sur les figures 1 et 2 des dessins, on a illustré en perspective partielle un équipement de tri postal selon l'invention.On the Figures 1 and 2 drawings, a partial sorting equipment according to the invention has been illustrated in partial perspective.

Cet équipement comprend une machine de tri postal 1 avec une entrée d'alimentation 2 (magasin du dépileur) dans laquelle des articles de courrier P, plus particulièrement des articles de courrier plats de grand format, sont disposés en pile sur chant.This equipment includes a postal sorting machine 1 with a feed inlet 2 (unstacker magazine) in which P mail items, more particularly large format flat mail items, are placed in a stack on edge.

La machine de tri 1 comprend encore de façon classique un convoyeur de tri 3, par exemple un convoyeur de tri à bandes de pincement, dans lequel les articles de courrier P sont déplacés en série sur chant vers des sorties de tri 4 où ils peuvent être stockés en pile à plat dans des bacs de stockage 5 à ouverture sur le dessus. On considère ici que les bacs de stockage 5 illustrés sur les figures sont placés dans les sorties de tri mais l'invention peut s'étendre à un équipement dans lequel il y un transvasement manuel du contenu des sorties de tri vers des bacs de stockage 5 illustrés sur les figures.The sorting machine 1 also conventionally comprises a sorting conveyor 3, for example a sorting conveyor with pinch bands, in which the mail items P are moved in series on edge towards sorting outlets 4 where they can be stored in flat stack in storage bins 5 with opening on top. It is considered here that the storage bins 5 illustrated in the figures are placed in the sorting outlets but the invention can extend to equipment in which there is a manual transfer of the content of the sorting outlets to storage bins 5 illustrated in the figures.

Sur les figures 1 et 2, le convoyeur de tri 3 est représenté très partiellement mais il est entendu qu'il peut comprendre un très grand nombre de sorties de tri 4.On the Figures 1 and 2 , the sorting conveyor 3 is shown very partially but it is understood that it can include a very large number of sorting outlets 4.

Sur les figures 1 et 2, on a illustré un échangeur de bacs 7 qui est traversé par un convoyeur 7A de bacs de stockage 5 et un convoyeur 7B de bacs navette 8.On the Figures 1 and 2 , a tray exchanger 7 has been illustrated which is crossed by a conveyor 7A of storage trays 5 and a conveyor 7B of shuttle trays 8.

Les figures 3 et 4 montrent en perspective un bac navette 8. Celui-ci est globalement en forme de dièdre en V pour stocker des articles de courrier P sur chant.The figures 3 and 4 show in perspective a shuttle tray 8. This is generally in the form of a V-shaped dihedron for storing mail items P on edge.

Le bac navette 8 comprend un fond incliné 8A, une paroi arrière 8B, un flanc latéral 8C et une ouverture frontale 8D.The shuttle tray 8 comprises an inclined bottom 8A, a rear wall 8B, a lateral flank 8C and a front opening 8D.

Le fond incliné 8A est formé ici par quatre nervures parallèles 8A1-8A2,8A3,8A4 qui s'étendent suivant la direction longitudinale D du bac 8 de façon oblique par rapport au socle plan 8E du bac.The inclined bottom 8A is formed here by four parallel ribs 8A1-8A2.8A3.8A4 which extend in the longitudinal direction D of the container 8 obliquely to the flat base 8E of the container.

Comme visible sur les figures 3 et 4, le socle 8E présente une certaine épaisseur constante entre l'avant et l'arrière du bac suivant la direction longitudinale D ce qui permet de munir le bac de deux poignées de manutention 8F à l'avant et à l'arrière du bac dans l'épaisseur du socle.As seen on figures 3 and 4 , the base 8E has a certain constant thickness between the front and the rear of the container in the longitudinal direction D, which makes it possible to provide the container with two handling handles 8F at the front and at the rear of the container in the 'thickness of the base.

Comme visible sur les figures 3 et 4, la surface supérieure du socle est parallèle à la surface inférieure du socle, la surface supérieure s'étendant entre les nervures 8A1 et 8A2, les nervures 8A2 et 8A3, et les nervures 8A3 et 8A4.As seen on figures 3 and 4 , the upper surface of the base is parallel to the lower surface of the base, the upper surface extending between the ribs 8A1 and 8A2, the ribs 8A2 and 8A3, and the ribs 8A3 and 8A4.

Les poignées 8F débouchent aussi dans la surface supérieure du socle 8E entre les nervures 8A2 et 8A3.The handles 8F also open into the upper surface of the base 8E between the ribs 8A2 and 8A3.

Les nervures 8A1 à 8A4 ont un profil en pente décendante (environ 15°) par rapport à la surface supérieure du socle 8E quand on va de l'ouverture 8D (à l'avant) vers la paroi arrière 8B du bac navette ce qui fait que le fond incliné 8A du bac qui est constitué par le dessus des nervures obliques 8A1 à 8A4 se trouve au dessus de la surface supérieure du socle 8E et laisse un espace pour l'insertion d'une fourche de convoyage comme expliqué plus loin.The ribs 8A1 to 8A4 have a downwardly sloping profile (about 15 °) relative to the upper surface of the base 8E when going from the opening 8D (at the front) towards the rear wall 8B of the shuttle tray which makes that the inclined bottom 8A of the tank which is constituted by the top of the oblique ribs 8A1 to 8A4 is located above the upper surface of the base 8E and leaves a space for the insertion of a conveying fork as explained below.

La paroi arrière 8B du bac navette 8 est en forme de dents de peigne et comprend des dents 8B1 à 8B4 qui sont dans la continuité des nervures 8A1 à 8A4 et qui ont une face tournée vers l'intérieur du bac qui est oblique (environ 15° d'inclianaison) par rapport au socle du bac et une face tournée vers l'extérieure du bac qui est perpendiculaire au socle du bac.The rear wall 8B of the shuttle tray 8 is in the form of comb teeth and comprises teeth 8B1 to 8B4 which are in the continuity of the ribs 8A1 to 8A4 and which have a face facing the inside of the tray which is oblique (about 15 ° of inclination) with respect to the base of the tank and one side facing the outside of the tank which is perpendicular to the base of the tank.

Le flanc latéral 8C raccorde ici la nervure 8A1 à la dent 8B1 pour fermer le dièdre en V.The lateral flank 8C here connects the rib 8A1 to the tooth 8B1 to close the V-shaped dihedron.

A l'avant du bac navette, l'extrémité des nervures 8A1 à 8A4 forme une sorte d'arrête qui saille légèrement en direction du dessus du bac navette.At the front of the shuttle tray, the end of the ribs 8A1 to 8A4 forms a sort of stop which projects slightly towards the top of the shuttle tray.

Par ailleurs, la surface intérieure de la paroi arrière 8B à l'extrémité libre des dents 8B1 à 8B4 forme une sorte d'arrête qui saille en direction du dessus du bac perpendiculairement à la surface supérieure du socle 8E.Furthermore, the inner surface of the rear wall 8B at the free end of the teeth 8B1 to 8B4 forms a sort of stop which projects towards the top of the tank perpendicular to the upper surface of the base 8E.

Comme illustré sur les figures 1 et 2, le convoyeur 7A est conçu pour transporter des bacs de stockage 5 remplis d'articles de courrier P empilés à plats depuis un point de chargement (par exemple une sortie de tri de la machine de tri 1) jusqu'a l'échangeur 7 et pour transporter des bacs de stockage 5 vides de l'échangeur jusqu'à un point d'entreposage de bacs vides. Le sens de circulation des bacs de stockage 5 dans le convoyeur 7A est indiqué par les flèches C1As illustrated on Figures 1 and 2 , the conveyor 7A is designed to transport storage bins 5 filled with mail items P stacked flat from a loading point (for example a sorting outlet of the sorting machine 1) to the exchanger 7 and to transport empty storage bins from the exchanger to an empty bins storage point. The direction of movement of the storage tanks 5 in the conveyor 7A is indicated by the arrows C1

Le convoyeur 7B est raccordé à l'entrée d'alimentation 2. Il est adapté pour amener des bacs navette 8 vides depuis l'entrée d'alimentation 2 vers l'échangeur 7 et transporter les bacs navette 8 remplis d'articles de courrier en pile sur chant depuis l'échangeur 7 vers l'entrée d'alimentation 2. Le sens de circulation des bacs navette 8 dans l'le convoyeur 7B est indiqué par les flèches C2.The conveyor 7B is connected to the feed inlet 2. It is suitable for bringing empty shuttle trays 8 from the feed inlet 2 to the exchanger 7 and transporting the shuttle trays 8 filled with mail items. pile on edge from the exchanger 7 to the feed inlet 2. The direction of movement of the shuttle trays 8 in the conveyor 7B is indicated by the arrows C2.

Dans l'exemple de réalisation, les bacs navette 8 ont une capacité de stockage plus grande que celle des bacs de stockage 5. Par exemple, on peut prévoir une capacité triple de celle des bacs de stockage 5.In the exemplary embodiment, the shuttle trays 8 have a greater storage capacity than that of the storage trays 5. For example, one can provide a capacity triple that of the storage trays 5.

Les figures 5A à 5J illustrent les différentes manipulations du bac de stockage 5 pour effectuer un transvasement de son contenu dans un bac navette 8, ici par un retournement à environ 180° - 15° à 25° (angles de la figure 6B) du bac de stockage 5.The Figures 5A to 5J illustrate the different manipulations of the storage tank 5 to transfer its contents to a shuttle tank 8, here by turning it around 180 ° - 15 ° to 25 ° (angles of the figure 6B ) from the storage bin 5.

Au début de la manipulation sur les figures 5A à 5D, le bac de stockage a son ouverture orientée vers le haut. Un bras manipulateur (absent sur les figures) vient la recouvrir d'une plaque 9.At the start of the manipulation on the Figures 5A to 5D , the storage bin has its opening facing upwards. A manipulator arm (absent in the figures) covers it with a plate 9.

Sur les figures 5F à 5G et sur la figure 5H, le bras manipulateur retire la plaque 9 (couvercle) ce qui fait que les articles de courrier P tombent dans le fonds du bac navette 8 en se positionnant en pile sur chant.On the figures 5F to 5G and on the figure 5H , the manipulator arm removes the plate 9 (cover) so that the mail items P fall into the bottom of the shuttle tray 8 by positioning in a pile on edge.

Sur les figures 5I à 5J, le bras manipulateur replace le bac de stockage vide 5 sur le convoyeur 7A pour un recyclage du bac de stockage par exemple dans une des sorties de tri de la machine de tri.On the figures 5I to 5J , the manipulator arm replaces the empty storage bin 5 on the conveyor 7A for recycling the storage bin, for example in one of the sorting outlets of the sorting machine.

Les figures 5A à 5J illustrent un transvasement du contenu d'un bac de stockage 5 vers un bac navet te 8 déjà chargé en articles de courrier P. Dans l'exemple illustré, le bac navette 8 a une capacité triple de celle d'un bac de stockage 5 et peut donc recevoir le contenu de trois bacs de stockage 5 transportés consécutivement sur le convoyeur 7A.The Figures 5A to 5J illustrate a transfer of the contents of a storage bin 5 to a turnip bin te 8 already loaded with mail items P. In the example illustrated, the shuttle bin 8 has a capacity triple that of a storage bin 5 and can therefore receive the contents of three storage bins 5 transported consecutively on the conveyor 7A.

Dans l'échangeur de bacs 7, le fond du bac navette 8 en cours de transvasement est orienté préférentiellement de façon oblique par rapport aux directions horizontale (par exemple avec un angle entre 15 et 25°) et verticales (par exemple un angle entre 5 et 15°) comme illustré sur les figures 6A et 6B pour créer un effet de taquage par gravité contre le flanc latéral 8C de la pile d'articles de courrier sur chant P, la début de pile étant en appui contre la paroi arrière 8B.In the tank exchanger 7, the bottom of the shuttle tank 8 during transfer is preferably oriented obliquely to the horizontal (for example with an angle between 15 and 25 °) and vertical (for example an angle between 5 and 15 °) as illustrated on the Figures 6A and 6B to create a jogging effect by gravity against the lateral flank 8C of the stack of mail items on edge P, the start of the stack being in abutment against the rear wall 8B.

Il est entendu que pendant l'opération de transvasement des articles de courrier P dans le bac navette 8, le convoyeur 10B est à l'arrêt ainsi que le convoyeur 10A.It is understood that during the operation of transferring the mail items P into the shuttle tray 8, the conveyor 10B is stopped as well as the conveyor 10A.

Comme visible sur la figure 5B, en position de transvasement, le bac navette 8 a sa paroi arrière 8B qui est disposée sous l'ouverture frontale 8D. Quand le bac navette 8 rempli d'articles de courrier P sort de l'échangeur 7, il est repositionné sur le convoyeur 7B de telle façon que sa paroi arrière 8B se trouve devant son ouverture frontale 8D.As visible on the figure 5B , in the transfer position, the shuttle tray 8 has its rear wall 8B which is arranged under the front opening 8D. When the shuttle tray 8 filled with mail items P leaves the exchanger 7, it is repositioned on the conveyor 7B so that its rear wall 8B is in front of its front opening 8D.

Sur les figures 7A à 7F, on a illustré les différentes étapes de chargement des articles de courrier P arrivant dans des bacs navette 2 dans l'entrée d'alimentation 2 de la machine de tri.On the Figures 7A to 7F , the various stages of loading the mail items P arriving in shuttle bins 2 in the feed inlet 2 of the sorting machine have been illustrated.

Comme visibble sur ces figures, le convoyeur 7B est raccordé en entrée sur le même plan horizontal que le tapis de convoyage motorisé 2C du dépileur de l'entrée d'alimentation 2 mais il est raccordé en sortie en dessous du plan horizontal du magasin du dépileur.As visible in these figures, the conveyor 7B is connected at the inlet on the same horizontal plane as the motorized conveyor belt 2C of the destacker of the feed inlet 2 but it is connected at the outlet below the horizontal plane of the destacker magazine .

Sur les figure 7A à 7F, on a illustré la plaque de dépilage 10 du dépileur de la machine de tri et aussi une palette de retenue de pile 11 qui sert à faire avancer la pile d'articles de courrier P vers la plaque de dépilage.On the figure 7A to 7F , the unstacking plate 10 of the unstacker of the sorting machine has been illustrated, and also a stack retaining pallet 11 which is used to advance the stack of mail articles P towards the unstacking plate.

Le magasin d'alimentation 2A a une sole motorisée constituée ici par des courroies motorisées parallèles espacées entre elles d'une distance suffisantes pour faire passer les nervures 8A1 à 8A4 et les dents 8B1 à 8B4 d'un bac navette 8.The feed store 2A has a motorized sole formed here by parallel motorized belts spaced apart by a sufficient distance to pass the ribs 8A1 to 8A4 and the teeth 8B1 to 8B4 of a shuttle tray 8.

Plus particulièrement, le magasin d'alimentation 2A du dépileur est en forme de fourche avec ici trois dents 2B qui sont constituées chacune par une courroie motorisée qui s'étend horizontalement vers le convoyeur 7B.More particularly, the feed magazine 2A of the destacker is in the form of a fork with here three teeth 2B which are each constituted by a motorized belt which extends horizontally towards the conveyor 7B.

Le fond de la fourche à dents 2B du magasin s'étend globalement jusqu'à la plaque de dépilage 10. Le magasin d'alimentation 2A comporte aussi une section de convoyage formée par un tapis de convoyage motorisé 2C qui est disposé en dessous des dents motorisées et qui est mobile en élévation verticalement, l'espace entre les dents 2B et le tapis de convoyage correspondant à l'épaisseur du socle 8E d'un bac navette 8.The bottom of the store's 2B tine fork extends generally up to the unstacking plate 10. The supply magazine 2A also includes a conveying section formed by a motorized conveyor belt 2C which is arranged below the motorized teeth and which is movable in vertical elevation, the space between the teeth 2B and the conveyor belt corresponding to the thickness of the base 8E of a shuttle tray 8.

En avançant vers la plaque de dépilage 10 du dépileur, le bac navette 8 rempli d'articles de courrier P sur chant est enfourché par les dents 2B du magasin du dépileur qui viennent s'insérer sous la pile d'articles de courrier entre les nervures 8A1 à 8A4 tandis que le socle 8E du bac navette vient reposer sur le tapis motorisé 2C.Advancing towards the unstacking plate 10 of the destacker, the shuttle tray 8 filled with mail items P on edge is straddled by the teeth 2B of the destacker magazine which are inserted under the stack of mail items between the ribs 8A1 to 8A4 while the base 8E of the shuttle tray comes to rest on the motorized conveyor 2C.

Ce faisant, le bac navette 8 est déplacé contre la plaque de dépilage 10 où le cas échéant à l'arrière d'une pile d'articles de courrier déjà présente dans le magasin d'alimentation comme montré sur les figures 7A à 7C.In doing so, the shuttle tray 8 is moved against the unstacking plate 10 or, where appropriate, behind a stack of mail items already present in the food store as shown in the Figures 7A to 7C .

Comme on peut le comprendre des figures 7A à 7F, la plaque de retenue 11 est placée initialement à l'arrière de la pile d'articles de courrier P déjà engagée devant la plaque de dépilage 10.As can be understood from Figures 7A to 7F , the retaining plate 11 is initially placed at the rear of the stack of mail items P already engaged in front of the unstacking plate 10.

Le bac navette 8 arrive à l'arrière de cette pile d'articles de courrier, la paroi arrière 8B en avant.The shuttle tray 8 arrives at the rear of this stack of mail items, the rear wall 8B in front.

Dès que le bac navette 8 est en butée contre la face arrière de la palette de retenue, l'Opérateur machine manipule la palette de retenue et la place à l'arrière (face à l'ouverture frontale du bac navette), du bac de retenue suivant la direction d'avancement de la pile devant la plaque de dépilage.As soon as the shuttle tray 8 is in abutment against the rear face of the retaining pallet, the machine operator manipulates the retaining pallet and places it at the rear (facing the front opening of the shuttle tray), of the retained in the direction of advancement of the stack in front of the unstacking plate.

Puis l'Opérateur machine commande la descente du tapis motorisé 2C vers le bas, par exemple en enfonçant un bouton de commande non représenté. Sur la figure 7D, on a illustré le tapis motorisé 2C dans une position intermédiaire de descente.Then the Machine Operator controls the descent of the 2C motorized belt down, for example by pressing a control button not shown. On the figure 7D , the motorized belt 2C has been illustrated in an intermediate descent position.

Pendant la descente du bac navette 8, les articles de courrier P sont retenus sur chant par les dents 2B du magasin.During the descent of the shuttle tray 8, the mail items P are retained on edge by the teeth 2B of the store.

Sur la figure 7E, le tapis motorisé 2C est maintenant dans le même plan horizontal que le convoyeur 7B et le bac navette 8 vide peut être déplacé sur le convoyeur 7B pour revenir vers l'échangeur 7.On the figure 7E , the motorized conveyor 2C is now in the same horizontal plane as the conveyor 7B and the empty shuttle tray 8 can be moved on the conveyor 7B to return to the exchanger 7.

Dans l'exemple illustré, le convoyeur 7B arrive dans et repart de l'échangeur 7 sur deux niveaux décalés verticalement.In the example illustrated, the conveyor 7B arrives in and leaves the exchanger 7 on two levels offset vertically.

Sur la figure 7F, le bac navette 8 vide a quitté le tapis motorisé 2C lequel peut alors remonter automatiquement pour prendre en charge un nouveau bac navette 8 rempli d'articles de courrier.On the figure 7F , the empty shuttle tray 8 has left the motorized conveyor belt 2C which can then automatically rise to take charge of a new shuttle tray 8 filled with mail items.

L'agencement de l'équipement de tri selon l'invention avec les bacs navette simplifie les manipulations de l'Opérateur machine puisque cet Opérateur n'a plus qu'une seule palette de retenue à manipuler pour maintenir sur chant devant le dépileur, les piles d'articles de courrier déchargées des bacs navette.The arrangement of the sorting equipment according to the invention with the shuttle trays simplifies the manipulations of the machine operator since this operator has only one retaining pallet to handle in order to keep on edge in front of the destacker, the stacks of mail items unloaded from shuttle bins.

Par ailleurs, le bac navette a de préférence une capacité de stockage en articles de courrier qui est supérieure à la capacité de stockage d'un bac de stockage, par exemple 3 fois supérieure, et l'échangeur de bac est alors agencé pour transvaser plusieurs bacs de stockage dans un même bac navette ce qui permet d'obtenir un plus grand débit d'environ 20000 articles de courrier à l'heure.Furthermore, the shuttle bin preferably has a storage capacity for mail items which is greater than the storage capacity of a storage bin, for example 3 times greater, and the bin exchanger is then arranged to transfer several storage bins in the same shuttle bin which allows a higher throughput of around 20,000 mail items per hour.
