[0043] Fig. 1 schematically and partially represents, in top view, a logistics distribution center 1 comprising several storage and distribution facilities 2 for merchandise items 3.

[0044] Each storage and distribution facility 2 for merchandise items 3 here comprises a plurality of storage columns 4 which are configured to receive and deliver the merchandise items 3.

[0045] To this end, each storage and distribution facility 2 for merchandise items 3 further includes a loading device 5 configured to load the merchandise items 3 into the plurality of storage columns 4.

[0046] Each storage and distribution installation 2 for merchandise articles 3 further comprises here a conveyor 6 which is arranged under the plurality of storage columns 4 and which runs here beyond the storage columns 4.

[0047] Each conveyor 6 is configured to receive one or more merchandise items 3 from one or more storage columns 4

[0048] Each storage and distribution facility 2 for merchandise items 3 further comprises herein assembly and / or packaging stations 7 arranged at one end of the respective conveyors 6.

[0049] The assembly and / or packaging stations 7 are configured to receive the merchandise items 3 which are conveyed by the conveyors 6.

[0050] This allows for the processing of orders, each containing at least one reference of one of the merchandise items 3, which are placed and received by the distribution logistics center 1.

[0051] Each storage and distribution facility 2 for merchandise items 3 further comprises herein a control and command unit 8 configured to receive a plurality of instructions from orders which are placed and received and which each include at least one reference to one of the merchandise items 3.

[0052] The control and command unit 8 is configured to control and command the distribution of the references of the order instructions from the storage columns 4 to the conveyors 6 and to the assembly and / or packaging stations 7.

[0053] In the illustrated example, the control and command unit 8 is interconnected with modules (not shown) that comprise all the storage and distribution installations 2 for merchandise items 3.

[0054] The distribution logistics center 1 here includes a shipping station 9 configured to receive, from the assembly and / or packaging stations 7, the merchandise items 3 of orders ready for shipment.

[0055] It should be noted that the logistics distribution center 1 here has particularly narrow aisles between the different storage and distribution facilities 2 and in particular between the different conveyors 6.

[0056] Figure 2 shows, in isolation and in front view, one of the installations of storage and distribution 2 of merchandise items 3.

[0057] The storage columns 4 are arranged substantially vertically between the conveyor 6 and an upper end forming a loading floor 10 at the level of which is located the loading device (not visible on the [Fig.2]) for the conveyance of the merchandise items 3.

[0058] Each storage column 4 is provided with a plurality of bins 11 which are superimposed and which are provided with one or more merchandise items 3.

[0059] The lockers 11 can be individual and / or removable and / or stackable.

[0060] The conveyor 6 comprises a plurality of receiving zones 12 which are delimited separated from each other by walls 13, which can be removable or fixed.

[0061] The reception zones 12 are therefore distinct from each other.

[0062] Each receiving area 12 is configured to receive one or more selected merchandise items 3 from one or more storage columns 4.

[0063] The conveyor 6 is thus configured to transport the merchandise items 3 arranged in the receiving areas 12 horizontally to the assembly and / or packaging station 7.

[0064] Alternatively, the merchandise items 3 can be directed by conveyor 6 to another installation and / or to another conveyor.

[0065] Figures 3 and 4 show an example of the realization of a locker 11, in a first configuration called closed, while figures 5 and 6 show the same locker 11 in a second configuration called open.

[0066] The locker 11 is provided with side walls 14 defining an internal space 15, an introduction opening 16 on the top of the internal space 15, and a release hatch 17 which is here formed of two rotating flaps articulated to the side walls 14.

[0067] The introduction opening 16 is provided to allow one or more articles of merchandise (not shown in figures 3 to 6) to be placed in the internal space 15 of the compartment 11.

[0068] The release hatch 17 is configured to allow a closed storage position for the item(s) of merchandise in the internal space 15, corresponding to the first so-called closed configuration of locker 11 (figures 3 and 4), and an open position for the distribution of the merchandise item(s), corresponding to the second so-called open configuration of locker 11 (figures 5 and 6).

[0069] To do this, the locker 11 includes an actuation mechanism 18 for the flaps of the hatch 17.

[0070] The actuation mechanism 18 is here provided with an electromagnetic element 19 configured to maintain the release hatch 17 in its closed storage position when the electromagnetic element is activated, and an elastic return element 20 configured to return the release hatch 17 from its closed storage position to its open distribution position.

[0071] When the electromagnetic device 19 is deactivated, the weight of the item(s) of merchandise rotates the flaps of the release hatch 17 to remove these items from the internal space 15 of the locker 11.

[0072] When the item(s) of goods are taken out of the locker 11, the elastic return member 20 returns the release hatch 17 to its closed storage position.

[0073] In particular, it is the actuation mechanism 18 which is controlled and commanded by the control and command unit (not shown in Figures 3 to 6) and which is therefore configured to control and command the passage of the release hatch 17 of the bin 11 closest to the conveyor (not shown in Figures 3 to 6), from its closed storage position to its open distribution position, so as to distribute from bin 11 at least one selected item of goods corresponding to at least one reference on a determined receiving area of ​​the conveyor, according to the command instruction received.

[0074] It should be noted that the locker 11 is designed to have an internal space 15 which has a volume allowing both to house the item(s) of merchandise and to articulate the flaps of the release hatch 17.

[0075] Figures 7 and 8 show an alternative embodiment of the locker 11, which differs from that shown in Figures 3 to 6 in that the actuation mechanism is provided here with an electric motor 21, or an electromagnet, controlled and commanded by the control and command unit and configured to actuate the flaps of the release hatch 17 from its closed storage position to its open distribution position, and vice versa, by means of a connecting rod 22 which is mechanically attached to the electric motor 21 and to each of the flaps of the release hatch 17.

[0076] Figures 9 and 10 show another embodiment of the locker 11, which differs from that shown in Figures 7 and 8 in that the release hatch 17 is formed by a single roller shutter that is hinged and mounted to slide along one of the side walls 14 of the locker 11, by means of an actuation mechanism provided of an electric motor 21 which is controlled and commanded by the control and command unit.

[0077] A method for preparing one or more orders of goods using the storage and distribution installation 2 of goods items 3 is described below with reference to [Fig.11].

[0078] The goods order preparation process includes the step of receiving 100 a plurality of order instructions each containing at least one reference of one of the goods 3, the step of selecting 101 a storage column 4 containing the reference in question, the step of controlling and controlling 102 the release hatch 17 of the bin 11 of the selected storage column 4 and simultaneously the conveyor 6 so as to distribute from bin 11 the reference in question onto a determined receiving area 12 of the conveyor 6.

[0079] These steps can be repeated depending on the number of references and merchandise items in the order instruction received by the control and command unit 8.

[0080] The process includes the step of conveying 103 the determined receiving area 12 from the conveyor 6 to the assembly and / or packaging station 7 and the step of packaging 104 the distributed merchandise item(s) 3.

[0081] The method includes the step of controlling and commanding 105 successively all the release hatches 17, from the bin 11 closest to the conveyor 6 to the bin 11 furthest from the conveyor 11 of the selected storage column 4.

[0082] Thus, the bin 11 closest to the conveyor 5 is always provided with at least one item of merchandise 3.

[0083] The method further comprises the step of loading or reloading 106 the plurality of storage columns 4 with the merchandise items 3 dedicated respectively to the storage columns 4, using the loading device 5 and at the level of the loading floor 10.

[0084] In the installation 2 described above, the plurality of storage columns 4 and the conveyor 6 arranged under these storage columns 4 are controlled and commanded by the control and command unit 8 which will allow, for example, the distribution of an item selected and stored in a dedicated storage column 4, onto a selected area among the receiving areas 12 delimited from each other.

[0085] To do this, the control and command unit 8 actuates the release hatch 17 of the locker 11 of the storage column 4 containing the selected item, at the moment when the selected receiving area 12 is opposite under the locker 11 in question.

[0086] In other words, installation 2 allows one or more orders to be prepared simultaneously, each containing one or more identical items or different, in a particularly simple and convenient way, while possibly increasing both the order processing rate and the number of item references stored in the installation.

[0087] It should be noted that the order preparation speed and the number of orders that can be processed simultaneously and / or successively may depend on the unit cycle for distributing a merchandise item, i.e., activating the release hatch and depositing the item on the determined receiving area of ​​the conveyor.

[0088] Variants not illustrated are described below.

[0089] The assembly and / or packaging stations can be arranged at least partially along the conveyors.

[0090] Each storage and distribution installation can include its own control and command unit and be operated independently of other installations.

[0091] Packaging and shipping can be done in the same station.

[0092] The distribution logistics center may be without aisles between the different storage and distribution facilities.

[0093] The lockers can be inseparable from one another.

[0094] The release hatches may have more than one or two hinged flaps.

[0095] More generally, the invention is not limited to the examples described and represented.
