Title:
POWDER FILLING DEVICE WITH REDUNDANT POWDER COLLECTION MECHANISM, AND ROTARY COMPRESSION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/051262
Kind Code:
A1
Abstract:
A powder filling device is provided with: a powder filling unit (5) which fills powder into a mortar; a redundant powder collection unit (1) which is located downstream from the powder filling unit (5) and collects powder leaking from the powder filling unit and the mortar from the surface of a rotary table; a redundant powder conveyance unit (2) which can quasi-continuously convey the collected powder from the redundant powder collection unit (1) in a predetermined constant conveyance amount; a new molding powder supply unit (6) which supplies new molding powder into the device; a pre-mixing powder storage unit (3) which connects with the new molding powder supply unit (6) and the redundant powder conveyance unit (2) and stores the new molding powder supplied from the new molding powder supply unit and redundant powder conveyed by the redundant powder conveyance unit (2); and a powder mixing unit (4) which approximately uniformly mixing the new molding powder and the redundant powder that have been transferred from the pre-mixing powder storage unit (3), the powder filling unit (5) filling the powder approximately uniformly mixed by the powder mixing unit (4) into the mortar. The powder filling device enables the redundant powder to be collected and be reusable even in the case of a multi-layer tablet in which mixing of powder between layers is not permitted at all.
