Title:
POWDER FILLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/119778
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a powder filling device for filling powder to a container at an approximately uniform filling density. A powder filling device is provided with: a hopper (11) that has an opening (112) through which powder is supplied to a container (30), and is sealably and detachably attached to the container (30) so as to communicate with the container (30) through the opening (112); a powder supply part (12) for supplying the powder to the hopper (11); a gas supply part (13) for repeatedly supplying compressed gas into the hopper (11) in a pulsed form while the hopper (11) and the container (30) are caused to communicate with each other and sealed; and a grid member (113) that is provided in the opening (112) and has a grid finer on the side wall side of the hopper (11) than on the center side thereof. By making the grid on the side wall side of the hopper (11) on which the powder easily falls from the hopper (11) into the container (30) finer, the falling of the powder there is suppressed, and the filling density is made uniform as a whole.
