Abstract
A packaging apparatus having a filling station, a downwardly opening nozzle at the filling station for dispensing a stream of semi-fluid material, means for advancing containers past the filling station, and container elevator means at the filling station for lifting a container into a position in which the upper portion of the container extends around the nozzle. Continuously driven container feed rollers are mounted at opposite sides of the nozzle and are operated in timed relation with the container elevator, first toward the nozzle to feed the container upwardly along the nozzle and then away from the nozzle to allow the container to move down as it is filled.
Claims11
In a packaging apparatus having a filling station, a downwardly opening nozzle at the filling station for dispensing a stream of semi-fluid material, means for advancing containers along a path below the nozzle, container elevator means at the filling station engageable with the underside of a container for elevating a container into a preselected raised position in which the upper portion of the container extends around the lower portion of the nozzle, the improvement comprising container feed roller means, means mounting the feed roller means for rotation about a generally horizontal axis alongside the nozzle and for shifting movement toward and away from the nozzle, means for driving the feed roller means in a direction to feed a container upwardly along the nozzle, and means for shifting the feed roller means toward the nozzle to engage a container when the latter is elevated by the container elevator means to said preselected raised position to further elevate the container around the nozzle and for thereafter shifting the feed roller means away from the nozzle to allow the container to move downwardly as it is filled.
In a packaging apparatus having a filling station, a downwardly opening filling nozzle for dispensing a stream of semi-fluid material, means for advancing containers along a path below the nozzle, container elevator means at the filling station engageable with the underside of a container for elevating a container into a preselected raised position in which the upper portion of the container extends around the lower portion of the nozzle, the improvement comprising, first and second container feed roller means, means mounting the first and second feed roller means for rotation about generally horizontal axes along opposite sides of the nozzle and for shifting movement toward and away from the nozzle, means for driving the first and second feed roller means in relatively opposite directions and such as to feed a container upwardly along the nozzle, and means for shifting the first and second feed roller means toward the nozzle to engage a container when the latter is elevated by the container elevator means to said preselected raised position to further elevate the container around the nozzle and for thereafter shifting the first and second feed roller means away from the nozzle to allow the container to move downwardly.
