New bulk bag filling line automatically dispenses pallets, fills bulk bags and accumulates filled bags for removal by forklift. The dispenser, which holds up to 15 pallets, is equipped with a powered roller conveyor that removes the bottom-most pallet from the stack, and positions it directly beneath the cantilevered fill head of a bulk bag filler. An operator then connects an empty bag to four actuated bag strap hooks, seals the bag spout using an inflatable collar, and presses a bag inflation button to initiate a seven-step automated filling sequence: start a conveyor to fill the bag at high rate; reduce the feed rate to dribble speed as the target weight is approached; stop the conveyor once the target rate is achieved; vibrate the pallet to densify and stabilize the bag; deflate the spout seal; release the bag loops; and release the pallet with newly filled bag (and any previously filled bags) to roll to the furthest of three downstream conveyor positions.
