SHUTTER MECHANISM AND POWDER FILLING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a shutter mechanism which is designed so as not to depend on turning force of an auger in order to eliminate defections arising from operation of the auger, and also to provide a powder filling apparatus equipped with the shutter mechanism. SOLUTION: The shutter mechanism 21 is arranged at a base 22a side of a hopper 22 storing powder for controlling fall of the powder filling through an opening 22c formed at the base 22a of the hopper 22. A mesh 25 which allows the powder to pass therethrough while stopping the powder from passing, being condensed and stagnant at usual times is provided at the upside of the opening 22c for covering the opening 22c. A vibrator 26 which gives vibration to the mesh 25 is provided at the hopper 22.
