Abstract
A packaging processing (liquid filling) apparatus, including a rising-and-lowering assembly attached to a pivot member and moved vertically and filling nozzles attached to the rising-and-lowering assembly. An endless chain having grippers at equal intervals is rotated continuously by a sprocket. A circular first raising-and-lowering cam that rotates with the sprocket is attached to the sprocket, and a circular-arc-shaped second raising-and-lowering cam is provided near the first raising-and-lowering cam; and a cam roller attached to the rising-and-lowering assembly is caused to roll on these cams. When the pivot member makes a forward motion to follow the bags held by grippers, the cam roller rolls over the second raising-and-lowering cam, and the rising-and-lowering assembly is lowered and then raised; when the pivot member makes a return motion, the cam roller rolls over the first raising-and-lowering cam, and the rising-and-lowering assembly is maintained in a raised position.
