Powder filling machine
First Claim
1. In the powder filling machine of the type wherein, (A) distribution of the powder to each of measuring-aperture aligned with constant spacings along a circle inside a circumference of a filling-turntable of flat surface rotatably supported around an upright center shaft mounted on a base of the machine of flat surface which also serves for carrying containers and equipped with a means for rotating the same, (B) measurement of the amount of the powder to be filled for a single shot, are performed by (a) forming a heap of powder into or around the aperture and then by (b) levelling off the heap with a reservoir for storing the powder mounted over the filling-turntable partly covering the surface of said turntable and having a closed side wall capable of (i) confining the powder within the reservoir and of (ii) levelling off the heap, and (C) sluicing-down of that measured amount of powder into an empty container placed underneath the measuring-aperture is effected by opening usually shut bottom outlet of the aperture in a timed sequence and in accordance with their angular position when they are in vertically aligned relationship, an improvement which comprises:
- 1. a measure-holding turntable having substantially the same configuration, including measure-receiving openings which correspond to the measuring-apertures, as the superimposing filling-turntable and being supported coaxial and rotatable with the filling-turntable, but permitted of vertical displacement with respect to the filling-turntable;
2. a plurality of bottomless inner measures, each having a hollow of inverted frusto-conical section and a straight outer stem, the root portion of which is secured by each of said measure-receiving openings and the upper portion is telescopically inserted into each of the measuring-apertures to form a composite measure of varying capacity, and3. a means for adjusting the height of the measure-holding turntable to vary the capacity of said composite measure which is dependent upon the distance between the turntables, simultaneously with that of the container placed underneath the apertures to combine the mouth of the container with the bottom of the aperture.

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.
