Abstract

In a rotary compressive molding machine for powder material wherein powder material filled in a die hole of a die mounted on a rotary table is compressed and molded between a lower end face of the upper punch and an upper end face of the lower punch, a powder lubricant spraying means that sprays powder lubricant comprises a spray nozzle that has a concave face facing to the lower end face of the upper punch or the upper end face of the lower punch at a position where the powder lubricant is sprayed and that sprays the powder lubricant generally toward a direction of the lower end face of the upper punch or the upper end face of the lower punch guided by the concave face, an air current supply mechanism that prevents the powder lubricant sprayed from the spray nozzle from scattering upward by spraying air near the lower end face of the upper punch, and an electrostatic charge device that electrizes the powder lubricant when the powder lubricant is sprayed from the spray nozzle and that electrizes at least the upper punch, the lower punch and the die with an antipolarity against the electrized powder lubricant.

Description

technical field

[0001] The present invention relates to a rotary powder compression molding machine for compression molding powder into tablets and the like. Background technique

[0002] In the past, when such a rotary powder compression molding machine was used to manufacture tablets, if the raw material powder of the tablet was composed of only the ingredients of the drug prescription, the raw material powder of the tablet or the tablet would stick to the pestle and the mortar, causing problems such as so-called sticking. . In order to prevent this sticking, a powder lubricant such as magnesium stearate is mixed into the drug prescription ingredients, and the method of manufacturing the tablet from the raw material powder constituting the tablet is easy in the manufacture of the tablet, so this method has generally been used in the past.

[0003] In recent years, medical care for the elderly has been emphasized, and there has been an increasing demand for tablets that di...
