Abstract
A trigger assembly for use with an accumulation conveyor includes two opposing pivot brackets. A pair of carrier-type roller extend between the pivot brackets and are respectively mounted for rotation about shafts that mount the pivot brackets to the side channels of the accumulation conveyor. Two sensing rollers extend between the pivot brackets and are respectively mounted for rotation about shafts that pivot about the shafts of the carrier-type roller during actuation and deactuation of the trigger assembly. A common counterweight roller is positioned between the first and second carrier-type rollers and is mounted on a shaft that pivotally connects the links of each of the pivot brackets to bias the sensing rollers upwardly into the travel path of the conveyor.
