Abstract

A composite measure of varying capacity, composed of supplying-aperture of straight cylinder and an inside measure telescopically inserted into the aperture and having a hollow of frusto-conical section, is employed in order to improve accommodation of the known conventional capacity type rotary powder filling machine, to powder of varying bulk density. A turntable which receives the supplying-aperture, superimposes over another turntable which holds the inside measure, and the distance between the both, is adjustable during the operation in accordance with the variance in the bulk density. The height of the container transferring path is also adjustable simultaneously with that of the second turntable. Spouting of compressed-air through an annular nozzle the diameter of which approximates to that of the aperture as a flow parallel to their inside wall is effected to blow off remaining powder in the measure and clean the same when the nozzle is disposed on the aperture. Evacuation for removing air from an empty or partly filled container is made through an annular suction inlet capable of suctioning the air as a flow parallel to the inside wall of the container.
