APPARATUS AND METHOD FOR OBTAINING A PREDETERMINED AND REPEATABLE FILL MEASURE IN A BAG-IN-CAN DISPENSER

摘要

A pedestal carries a bag indexer to index an arch-shaped bottom of a bag that has been attached to the body by a bag applicator. The bag indexer has a pair of vacuum tubes for drawing an attached bag into a dispenser body against the mouths of the tubes and a shaft which engages and supports the apex of the bag's arch during indexing. The position of the bag indexer is adjustable to adjust the bag's fill measure. The bag indexer is extended from a retracted position after a dispenser body is received on the pedestal for transport to the bag applicator to facilitate dispenser body removal and placement on the pedestal from an input conveyor. The bag indexer is also retracted to facilitate removal of a dispenser body from the pedestal after a bag has been attached and indexed.
