摘要:
For filling successive spouted bags with a beverage or like fluid product to a prescribed weight, a filling valve assembly and a cap remover assembly are immovably mounted side by side in a germfree chamber formed over a weighing platform. After the germfree chamber and the interior of a filling head forming a part of the filling valve assembly have been sterilized, a bag is placed on or over the weighing platform, with its capped spout caught by a spout carrier arm, which is supported on the weighing platform for both linear up-and-down motion and pivotal motion about a vertical axis. Following the removal of the cap from the spout by the cap remover assembly, the arm carries the spout to a position under the filling valve assembly and holds the spout against the filling head. The fluid is first charged into the bag at a high rate to an extent slightly less than the prescribed weight and then, with the spout separated and held at a slight distance from the filling head, at a reduced rate to the prescribed weight as ascertained by the weighing platform. Sterilized air under pressure is introduced into the germfree chamber throughout the progress of the filling operation to maintain the chamber at a higher-than-atmospheric pressure.
