A system for buffer storage and sequencing of items that receives unsequenced items and delivers sequenced items is provided. The system includes: a buffer storage unit having N input levels each having a FIFO conveyor, where N&#x2265;2; reciprocating input and output elevators positioned respectively at the input and output of N input levels; and a control unit configured to organize, under a constraint of delivery to at least one forward output conveyor of at least one sequence of items, various movements of items (from at least one forward input conveyor to the reciprocating input elevator, from the reciprocating input elevator to the N input levels, from the N input levels to the reciprocating output elevator, and from the reciprocating output elevator to the at least one forward output conveyor).

Processing a list of customer orders with a control system and a preparing station, which includes a picking position, an insertion position and local recirculation. The control system: selects a reference in the greatest number of order lines of the list; determines a set E of all the Norders each containing an order line containing the selected reference; creates a group G of N orders that are the Norders, if N&#x2264;Nwith Nbeing a predetermined threshold, or the Nfirst orders of the Norders sorted according to decreasing order of priority, if N&#x3e;N; builds a list LC of the K order lines in the N orders of the group G; and controls the system to bring source loads to the picking position and ship loads to the insertion position and to make the shipping loads recirculate to the insertion position, according to the list LC.

A method for managing a buffer storage and load sequencing system, receiving non-sequenced loads, providing a sequence of loads, and including a buffer storage unit (having entrance levels, at least one recirculation level, and an entrance elevator facing entrances and an exit elevator facing exits of the levels. A management unit iteratively manages the entrance elevator by, at each iteration (even if there are loads to be recirculated in the system): selecting a load at exit from an entrance conveyor or at exit from the recirculation level; if the selection of one of the entrance levels is completed, generating a task for the entrance elevator of transferring the selected load to the entrance of the selected level; if not, selecting a level of loads to be recirculated and assigning the load(s) on this level a 'load(s) to be recirculated' status without generating a task of transfer for the entrance elevator.

Method for the management, in sorting mode, of a buffer storage and load sequencing system, and corresponding management unit

A method for managing a buffer storage and load sequencing system. The system receives non-sequenced loads and provides at least one sequence of loads, and includes a buffer storage unit having entrance levels, at least one recirculation level, an entrance elevator facing entrances and an exit elevator facing exits of the levels. A management unit iteratively manages the entrance elevator. At each iteration the entrance elevator: has a 'waiting for recirculation' status for a load to be recirculated in the system; holds this elevator until the load to be recirculated has been transferred to the recirculation level, else selects a load at exit from an entrance conveyor or at exit from the recirculation level; if the selection of the entrance level is completed, generates a task, for the entrance elevator, of transferring the selected load to the selected level; if not assigns this load the 'awaiting recirculation' status.

Method for the management, in flow mode, a buffer storage and load sequencing system, and corresponding management unit

A system of buffer storage and sequencing of loads is configured to receive non-sequenced loads coming from at least one external unit and to provide sequenced loads to at least one preparing station. The system includes: a reciprocating lift having a single nacelle with K levels each enabling transportation of at least one load with K&#x2265;2; at least one buffer storage unit; and a managing unit configured to organize first movements of loads from at least one inbound forward conveyor to the at least one buffer storage unit through the reciprocating lift, and second movements of loads from the at least one buffer storage unit to at least one outbound forward conveyor through the reciprocating lift.

System of buffer storage and sequencing of loads upstream to at least one preparing station

A system for sequencing a preparing station that sequences loads coming from an external unit via an entering outbound conveyor. The system includes a paternoster, a buffer location and a managing unit, which processes each load that comes to an entrance of the paternoster according to one of the following modes (selected as a function of a place desired for the load in a sequence): (a) after introduction into the paternoster, the load undergoes a bypass transfer between two nacelles positioned face to face and then presented to an exiting outbound conveyor; (b) after introduction into the paternoster, the load undergoes a buffer transfer towards a given buffer location and then subsequently re-positioned again in the paternoster and finally presented to the exiting outbound conveyor; (c) after introduction into the paternoster, the load is transported therein without bypass transfer or buffer transfer and then presented to the exiting outbound conveyor.

System and method of sequencing for at least one preparing station

An automated storage/retrieval system is proposed. The system includes a control system, at least one storage unit having several levels at which loads can be picked or deposited and at least one interface conveyor for entries/exits of loads into and out of the system, and at least one elevator for a transfer of loads between the at least interface conveyor and the at least one storage unit. The at least one elevator is a multi-level elevator, and the automated storage/retrieval system furthermore includes at least one multi-level transfer device capable of simultaneously receiving, on several levels, a set of loads intended for or coming from at least one elevator; and at least one sequencer provided with elements of vertical moving and capable of transferring loads between the at least one multi-level transfer device and the at least one interface conveyor.

An automated system for preparing parcels of products has a storage assembly housing product containers; a pick station; a main conveyor which conveys the product container between the inlet/outlet of the storage assembly and the pick station; and a central management computer system which manages the product order list associated with each parcel. The main conveyor arranges the containers according to an order list, using a first conveyor belt section, a second conveyor belt section adjacent to the pick station and a buffer zone between the outlet of the storage assembly and the first belt section. The containers are moved between the belt sections by transfer members in transfer zones.
