  • Powder filling device with redundant powder collection mechanism, and rotary compression molding machine
    Patent number: 9902087
    Abstract: Disclosed is a powdery material filling device with a redundant (i.e., excess or waste) powdery material recovering mechanism. The powdery material filling device may be used in a rotary compression molding machine. In certain aspects, the redundant powdery material recovering mechanism is capable of actively recovering and reusing a redundant (i.e., excess or waste) powdery material even upon production of multi-layer tablets.
    Type: Grant
    Filed: October 3, 2012
    Date of Patent: February 27, 2018
    Assignee: Sanwa Kagaku Kenkyusho Co., Ltd.
    Inventors: Yuichi Ozeki, Kentaro Izumi, Katsuhito Fujisaki, Kouichi Atagi

  • Punch of compression molding machine
    Patent number: 8657594
    Abstract: A punch of a compression molding machine is configured to be assembled with no use of any tool and achieves reduction in time necessary for the assembling process. The punch includes a punch tip member, a holder provided, at a distal end thereof, with a projection projecting radially outward, a cap having a disengagement inhibiting portion engaged with the projection of the holder so as to inhibit the projection from inserted thereinto and extracted therefrom in the axial direction, and a rotation inhibiting member engaged with the holder and the cap attached with the punch tip member so as to inhibit axial rotation of the cap relative to the holder.
