Abstract
Abstract A device for automatically filling and capping containers comprising a filler nozzle positioned above an elevator mechanism, a bag station spaced from and on one side of the filler nozzle and a cap station spaced from and on the opposite side of the filler nozzle, and a movable carriage having a cap chuck on one end and a bag chuck on the other and being mounted for controlled movement between the filler nozzle and the bag station and the filler nozzle and the cap station whereby when the carriage is moved to the bag station, a filled bag is capped at the cap chuck location and a new bag is simultaneously obtained by the bag chuck, when the carriage is moved to the cap station, the capped, filled bag is ejected, the newly obtained bag is received by the elevator mechanism and a new cap is substantially simultaneously obtained from the cap station and when the carriage is moved to an intermediate position, the elevator mechanism raises the new bag to be filled to the filler nozzle and lowers the filled bag to the capping position and the cycle repeats itself.
