System and method of sequencing for at least one preparing station

A method comprising:

• sequencing loads coming from at least one external unit through at least one entering outbound conveyor and for providing at least one preparing station, through at least one exiting outbound conveyor, with at least one sequence comprising loads in a desired sequential order, said sequencing being implemented in a system comprising:
• a managed elevator with nacelles, called a paternoster, circulating in a closed loop, each nacelle enabling the transportation of at least one load and being equipped with a device for transferring loads on to or out of said nacelle;
• at least one buffer location, configured to temporarily receive at least one load coming from the paternoster;
• and
• a managing unit;
• and wherein the sequencing comprises the managing unit organizing the movements of the loads in the system and processing each load that comes to the entrance of the paternoster through said at least one entering outbound conveyor, according to one of the following modes, selected according to a place desired for said load in said at least one sequence:
• (a) after introduction into the paternoster, the load undergoes a bypass transfer between two nacelles positioned face to face, by implementation of the load transfer devices of the two nacelles, and is then presented to said at least one exiting outbound conveyor;
• (b) after introduction into the paternoster, the load undergoes at least one buffer transfer towards a given buffer location and is then subsequently re-positioned in the paternoster and finally presented to said at least one exiting outbound conveyor;
• (c) after introduction into the paternoster, the load is transported therein without bypass transfer or buffer transfer and then presented to said at least one exiting outbound conveyor.
