Abstract
In the overall system, vertically disposed, primary bags are filled with articles to a predetermined weight and conveyor means conduct the filled primary bags to a discharge point where a predetermined number of said filled bags are discharged at a discharge point and fall into an upright master bag, after which the filled master bag is carried away and closed, and an empty bag is positioned to receive primary bags of said predetermined number from said conveyor means. During the interval of time when a filled master bag is moved away from the receiving point where it is filled, and an empty bag replaces it, the discharge of bags continues at said discharge point, but are accumulated until the replacement empty master bag is in receiving position, and then the accumulated bags are released to fall by gravity into the empty master container as a unit, and the passage through the accumulator remains open until the additional bags to make up the total required predetermined number pass directly into the primary bag from said discharge point. Also the conveyor means toward the discharge point is continuous up to a transfer location and is intermittent from said location to the discharge point, and control means automatically precludes the occurrance of an underfilled master bag without stopping or slowing the conveyor means.
