Abstract
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≥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).
