摘要： The present invention provides a method for manufacturing a molding with a core by using compression molding means having upper and lower double-structured punches; the method comprising the steps of supplying molding material for the core and molding material for the outer layer respectively, the step of compression-molding the molding material for the core and/or the molding material for the outer layer, and the step of compression-molding the whole molding with a core, wherein: the step of supplying the molding material for the outer layer posterior to the step of supplying the molding material for the core is performed until a tip of the lower center punch finally takes a position protruding from a tip of the lower outer punch; and the step of compression-molding the whole molding with a core is performed with the tips of the lower center punch and the lower outer punch aligned with each other. This method can be expected to bring about the effect of enhancing the strength of a portion of outer layer forming the sidewall of the molding and/or the effect of allowing the molding material for the outer layer supplied after the step of supplying the molding material for the core to be led to under the temporary molding of the core thereby making it possible to manufacture a molding with a core through the molding material supply step performed twice.

摘要： 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.

摘要： A powdery material filling device provided with a redundant powdery material recovering mechanism which is capable of actively recovering and reusing a redundant powdery material even upon production of multi-layer tablets in which powdery materials for different layers must not be mixed is provided. The device comprising: a powdery material filling unit for filling the dies with powdery material; a redundant powdery material recovering unit located downstream of the powdery material filling unit, for recovering, from the surface of the rotating die table, a powdery material leaked out of the powdery material filling unit and the dies; a redundant powdery material conveying unit capable of conveying the powdery material recovered by the redundant powdery material recovering unit quasi-continuously in a predetermined constant amount of conveyance; a new powdery molding material supplying unit for supplying the device with a new powdery molding material; a pre-mixed powdery material reserving unit connected to the new powdery molding material supplying unit and the redundant powdery material conveying unit, for reserving the new powdery molding material supplied from the new powdery molding material supplying unit and the redundant powdery material conveyed by the redundant powdery material conveying unit; and a powdery material mixing unit for mixing and substantially uniformizing the new powdery molding material and the redundant powdery material transferred from the pre-mixed powdery material reserving unit, wherein the powdery material filling unit fills the dies with the powdery material that is mixed and substantially uniformized in the powdery material mixing unit.
