Abstract

The storage-and-retrieval cell for a parcel-handling logistics platform includes shuttle robots that position parcels in storage locations and that retrieve the parcels therefrom, which locations form two rows of storage locations that extend along a longitudinal direction, and four half-rows of storage locations that are disposed back-to-back in the longitudinal direction between the two rows, a hopper being open in the upper floor between one pair of half-rows and the other pair of half-rows, the hopper being designed to allow the parcels to pass through it while they are being retrieved, the cell further including nesting trolleys each of which is suitable for being hitched to a shuttle robot and which are suitable for nesting together in the same storage location, and, at the edge of the hopper, an unloading device for unloading a nesting trolley by sweeping its deck.

First claim

What is claimed is:

1. A storage-and-retrieval cell for a parcel-handling logistics platform for handling parcels with a view to delivering them, said storage-and-retrieval cell comprising:
an upper floor and autonomously movable shuttle robots that move incoming parcels so as to position them in storage locations under the remote control of a monitoring and control unit, said monitoring and control unit configured to control said shuttle robots in such a manner that they retrieve said parcels from the locations in sequence, in which storage-and-retrieval cell said storage locations are distributed over said upper floor in such a manner as to form, firstly, two rows of storage locations that face each other and that extend in mutually parallel manner along a longitudinal direction, and, secondly, four half-rows of storage locations that are disposed back-to-back and in pairs, the two pairs of half-rows extending in alignment with each other in said longitudinal direction between said two rows of storage locations, said rows and half-rows of locations defining travel aisles between them on said upper floor for the shuttle robots to travel during storing and retrieval of parcels, and
in which storage-and-retrieval cell a vertical travel hopper for parcels is open in the upper floor between one pair of back-to-back half-rows and the other pair of back-to-back half rows, said hopper being configured to allow said parcels to pass through it vertically while they are being unloaded in sequence into the hopper using said shuttle robots under the control of said unit during retrieval, and
nesting trolleys each of which is suitable for being hitched to a shuttle robot and has a deck suitable for carrying a parcel, said nesting trolleys being of different heights and widths in such a manner as to be suitable for nesting together in the same storage location, and in that, at the edge of said hopper, said storage-and-retrieval cell further includes an automatic unloading device having at least one sweeper arm suitable for sweeping the deck of a nesting trolley carrying a parcel so as to cause said parcel to fall into the hopper under the effect of relative movement of the trolley and of the sweeper arm.

2. The storage-and-retrieval cell according to claim 1 , wherein it includes a plurality of upper floor levels, the hoppers of said upper floors being served by the same vertical conveyor.

3. The storage-and-retrieval cell according to claim 2 , wherein said vertical conveyor is a helical conveyor.

4. The storage-and-retrieval cell according to claim 3 , wherein said vertical conveyor is a gravity conveyor.

5. The storage-and-retrieval cell according to claim 2 , wherein said vertical conveyor is a gravity conveyor.

6. A parcel-handling logistics platform, comprising:
at least one storage-and-retrieval cell according to claim 1 , and,
on the ground floor, under said hopper, a parcel transporter that is suitable for transporting said parcels coming from said hopper in series towards a transport vehicle parked on the ground floor.

7. The logistics platform according to claim 6 , wherein it includes a plurality of adjacent cells with a common upper floor and a plurality of hoppers in the common upper floor, and, on the ground floor, under said hoppers, a plurality of parcel transporters suitable for serving a plurality of transport vehicles parked on the ground floor.

8. The logistics platform according to claim 7 , wherein it includes a feed inlet via which parcels are fed and which is provided with identification means for identifying each parcel so as to provide postal delivery address information, and in that said monitoring and control unit is arranged so that, on the basis of the address information of the parcels stored in the storage locations of a cell, said monitoring and control unit causes said shuttle robots to unload said parcels into the hopper of the cell in a certain postal delivery order in which the parcels are to be delivered that corresponds to a parcel loading order in which the parcels are loaded into the transport vehicle(s).

9. The logistics platform according to claim 6 , wherein it includes a feed inlet via which parcels are fed and which is provided with identification means for identifying each parcel so as to provide postal delivery address information, and in that said monitoring and control unit is arranged so that, on the basis of the address information of the parcels stored in the storage locations of a cell, said monitoring and control unit causes said shuttle robots to unload said parcels into the hopper of the cell in a certain postal delivery order in which the parcels are to be delivered that corresponds to a parcel loading order in which the parcels are loaded into the transport vehicle(s).
