METHOD FOR CONTROLLING THE FLOW MODE OF A BUFFER STORAGE SYSTEM AND FOR SEQUENCING LOADS, AND CORRESPONDING CONTROL UNIT

摘要

Method for controlling a buffer storage / charge sequencing system, receiving non-sequenced charges, supplying at least one sequence of charges, and comprising a buffer storage unit (comprising input levels (FIFOs in one direction) and at least one recirculation level (another FIFO in an opposite direction) and an input elevator and an output elevator positioned one facing the inputs and the other facing the outputs of the aforementioned levels. iteratively the input elevator. At each iteration: if the input elevator has the status "recirculation wait", meaning that there is at least one load to be recirculated in the system (204), put on hold (205 ) from this until the transfer of at least one charge to be recirculated to the recirculation level; otherwise: selection (206 to 211) of a charge at the output of an input conveyor or at the output of the recirculation; if the selectio n (213) of one of the entry levels succeeds, generation (219) for the entry elevator of a mission for transferring the selected load to the selected level, otherwise assignment (216) to it of "waiting for recirculation" status, selection (218) from the entry levels of a level to be recirculated (assignment of the status "to be recirculated" to the load (s) on it) (without generation for the lift entry of a transfer mission).
