  • Patent number: 9078807
    Abstract: A tablet compression machine which can manufacture a tablet having a plurality of layers by applying secondary compression molding to a columnar primary compression molded product formed by a plurality of layers and whose two bottom faces may be bulged, comprising at least a mortar, an upper pestle, and a lower pestle, in which the mortar is substantially in a shape in which a part of a flat plate is punched by a closed curve in a direction perpendicular to a plane of the flat plate, the upper and lower pestles are in a shape fitted with an inner face of the mortar, a space formed by an inner face of the mortar, a lower face of the upper pestle, and an upper face of the lower pestle is in a shape of an intended tablet in the secondary compression molding, a dent formed by the inner face of the mortar and the upper face of the lower pestle can constitute a shape suitable for receiving the primary compression molded product, and a direction of the secondary compression molding is different from the compression

  • Patent number: 8029261
    Abstract: A transfer board for transferring a columnar primary compression molded product which is supplied continuously one by one vertically in a shooter into a mortar of a secondary tablet compression machine, having at least an inclined portion having a plane-state inclined face, an input portion adjacent thereto, a portion for limiting drop of primary compression molded product, and a bottom plate provided at a lower part of the input portion, the inclined face being inclined so as to become lower toward the input portion, the inclined portion and the adjacent input portion performing a linear motion or rotary motion at a constant speed horizontally in a direction opposite to the input portion, and the input portion and the bottom plate being able to supply the primary compression molded product into the mortar of the secondary tablet compression machine while the columnar direction is kept substantially in a state of the horizontal direction.
