Abstract:
A process for bagging a predetermined number of grains with heterogeneous granulometry per sack, comprising:collecting grain out of a flow of grain intended to be bagged,subjecting the grain collected to a vibration operation to ensure distribution of the grain and take it to an acceleration device,passing the grains through an inclined acceleration chute in order to single them out,counting the grains by counting cells located at the bottom of acceleration channels,stopping the feed of the grains to the acceleration channels when n grains are counted,weighing the grains counted,sending the number n of grains and a mass of that number n of grains to a calculator which takes those measurements and finds a theoretical mass of a predetermined number of grains in a sack,filling a sack with a flow of grains, the sack being placed on a weighing system whose index value is the theoretical mass of the predetermined number of grains in a sack found by the calculator,ordering the bag filling to stop when the theoretical mass is measured by the weighing system,repeating the proceeding operations at predetermined intervals until the flow of grain to be bagged is exhausted, andupdating the index value of the weighing system each time the calculator finds the theoretical mass of the predetermined number of grains in a sack.
