ABSTRACT:
Method and apparatus for the controlled accumulating and feeding of piles of magazines from an input conveyor to a trimmer infeed conveyor. A flow director receives magazine piles and directs them to one of three parallel conveyor lanes, each lane including a series of independently driven conveyor sections. The leading pile in each lane is fed by a gate to the trimmer infeed conveyor while a restrictor restrains the succeeding piles from advancing. The procedure is repeated for each succeeding pile on each lane. Each section of each conveyor lane is provided with detectors for detecting stalled magazine piles. When stalled piles are detected at the downstream end of a conveyor section the adjacent downstream conveyor section is shut down. The traffic on the three lanes is compared and the flow director is instructed to not feed piles to a lane having an excessive backup of piles as compared to its neighbors.
