Direct Bag Filling System

The operator inserts the bag to the bag-clamping chute and presses the foot switch (a pneumatically operated bag clamping arrangement will clamp the bag).

The controller will check if the bag is clamped (sensor provided) and automatically tares the gross weight to obtain a Net weight. The material is then fed into the bag; a two-position sector gate controls the rate at which it is fed. The controller compares the actual weight with the target weight settings, when the Main/Coarse feed setting is reached the main feeder of the sector gate is latched, feeding continues in the Fine/Dribble feed mode. The material is fed in the fine feed mode until the Final Weight minus In-Flight value is reached, after which the Fine feeder is closed. Once the feeding is stopped a settling time (adjustable time, varies from 500ms to 2 sec) is given after which the end of batch is signaled, automatically the Totalizer and Bag Counter is updated. A lamp will indicate batch completion, after which the operator de-clamps the bag by acknowledging a switch.
