METHOD FOR CONTROLLING THE SORTING 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 (even if load (s) to be recirculated in the system): selection (204 to 209) of a load at the output of an input conveyor or at the output of the recirculation; if the selection of one of the input levels succeeds (211), generation (217) for the input elevator of a mission to transfer the selected load to the selected level, otherwise selection (216) from entry levels of a level to be recirculated and assignment of the status "to be recirculated" to the load (s) on it (without generation for the entry elevator of a transfer mission).
