En parallèle, l'augmentation du nombre de destinations physiques sur un même plan de tri nécessite d'augmenter le nombre de sorties de tri et donc l'emprise au sol de l'installation.At the same time, increasing the number of physical destinations on the same sorting plan requires increasing the number of sorting outlets and therefore the footprint of the installation.
Aussi, plus le nombre de sorties de tri sera important et plus les moyens de manutention mis en œuvre pour récupérer les colis devront être importants.Also, the greater the number of sorting outlets, the greater the handling means implemented to recover the packages will have to be.

L'idée à la base de l'invention est ici d'avoir un nombre de sorties de tri dites logiques, ou potentielles, plus important que le nombre de sorties de tri physiques. Pour cela chaque sortie de tri physique de l'équipement de tri est équipée de plusieurs réceptacles associés chacun à des informations de tri différentes.The basic idea of the invention here is to have a greater number of so-called logical or potential sorting outputs than the number of physical sorting outputs. For this, each physical sorting outlet of the sorting equipment is equipped with several receptacles each associated with different sorting information.
Un système de permutation de réceptacles est également prévu pour déplacer en rotation les réceptacles de la sortie de tri et pour en positionner un seul en position de remplissage sous la sortie de tri appropriée.A receptacle permutation system is also provided to move the receptacles of the sorting outlet in rotation and to position a single one in the filling position under the appropriate sorting outlet.
On comprendra par exemple que pour une sortie de tri physique comprenant quatre réceptacles associés chacun à une information de tri de colis différente, il y aura trois sorties logiques de plus qu'une simple sortie de tri physique munie d'un seul réceptacle.It will be understood for example that for a physical sorting outlet comprising four receptacles each associated with different parcel sorting information, there will be three more logic outputs than a simple physical sorting outlet provided with a single receptacle.
Ainsi, l'équipement de tri selon l'invention pourra desservir autant de sorties logiques que de réceptacles affectés à la sortie de tri physique et ce pour une emprise au sol équivalente à celle d'équipement de tri classique.Thus, the sorting equipment according to the invention will be able to serve as many logic outputs as there are receptacles assigned to the physical sorting output and this for a footprint equivalent to that of conventional sorting equipment.
L'invention consiste d'une part à réduire l'emprise au sol en proposant un système de permutation de bac à rotation verticale et d'autre part à maintenir les réceptacles à l'horizontal pendant leur rotation verticale à l'aide d'un système de synchronisation horizontale mécanique.The invention consists on the one hand in reducing the footprint by proposing a system for permutation of tray with vertical rotation and on the other hand in keeping the receptacles horizontal during their vertical rotation using a mechanical horizontal synchronization system.
Les réceptacles sont ainsi constamment maintenus à l'horizontal malgré la répartition aléatoire et du flux de chargement des colis dans les réceptacles.The receptacles are thus constantly kept horizontal despite the random distribution of the load flow of the packages in the receptacles.

- Device (1) for sorting parcels (2), comprising a sorting conveyor (3), sorting outlets (4) distributed along said conveyor and a control unit (7) which is capable of controlling the sorting conveyor for sorting the parcels in the sorting outlets on the basis of a certain piece of parcel sorting information, each sorting outlet being arranged to store a plurality of sorting receptacles (6) each associated with a piece of parcel sorting information in the memory of the control unit, characterized in that the device also comprises, at each sorting outlet, a device (8) for permutating receptacles comprising a shaft (8a) which is rotatable about a first horizontal axis of rotation (A1), the shaft being provided with supports (9) which are each designed to store and vertically rotate about the first axis of rotation a receptacle for parcels, and in that the control unit controls the permutation device for immobilizing a receptacle of which the piece of parcel sorting information associated in the memory of the control unit corresponds to the piece of information regarding sorting the current parcel to be sorted, into a filling position in which the receptacle is positioned under the sorting outlet for receiving a parcel.
- Sorting device according to claim 1, characterized in that the shaft comprises a plurality of arms (8b) which extend from the first axis of rotation and in that each arm comprises one of said supports freely rotatably mounted about a second horizontal axis of rotation (A2) which is offset relative to the first axis of rotation, each support being mounted in horizontal equilibrium relative to the offset axis of rotation.
- Sorting device according to claim 2, characterized in that the permutation device comprises a mechanical horizontal synchronization system (10) which is designed to synchronize all the supports in horizontal equilibrium during their vertical rotation about the first axis of rotation.
- Sorting device according to claim 3, characterized in that the mechanical horizontal synchronization system comprises a frame (11) on which the shaft is rotatably mounted about the first axis of rotation, a reference pinion (12) secured to the frame and sharing the first axis of rotation with the shaft, a synchronization pinion (13) secured to the support and freely rotatably mounted at the end of each arm about the second axis of rotation, and mechanical connections (14) rotatably connecting the synchronization pinions to the reference pinion in a synchronized manner.
- Sorting device according to claim 4, characterized in that said mechanical connections comprise a chain or toothed belt synchronization connection (14a) which connects in series all the synchronization pinions and a chain or toothed belt reference connection (14b) which connects the reference pinion to a single synchronization pinion.
- Sorting device according to claim 4, characterized in that said mechanical connections comprise chain or toothed belt reference connections which connect each synchronization pinion independently to the synchronization pinion.
- Sorting device according to any of the preceding claims, characterized in that the supports are in the form of nacelles having a bottom wall (PF) which is designed to support a receptacle, two side walls (PL) and two openings in the front face and the rear face which are designed to allow a receptacle to be unloaded by sliding.
- Sorting device according to any of the preceding claims, characterized in that the permutation device comprises a receptacle position detection system (16) which is capable of determining which receptacle of the sorting outlet is in the filling position, and in that the control unit comprises in the memory the scheduling of the receptacles at each sorting outlet and, in response to the detection of said detection system, controls the rotation of the permutation device for placing in the filling position the receptacle of which the piece of parcel sorting information corresponds to the piece of information regarding sorting the current parcel to be sorted.
- Sorting device according to any of the preceding claims, characterized in that it comprises a system for detecting the filling level (17) of the receptacle in the filling position, and in that in response to a certain threshold of the filling level of the receptacle being exceeded, the control unit controls the movement of the receptacle into a discharged position arranged to present the receptacle at an ergonomic height.
- Sorting device according to any of the preceding claims, characterized in that each sorting outlet is provided with a filling hopper which extends downward from the conveyor toward a receptacle in the filling position.
