While conveying using (16), the body and the cap (2) are separated in accordance with the working process sequence, the body separated and conveyed in a predetermined section is taken out from the conveying path, and the filling material feeding unit (20) presses the filling of the powder. Molded into a powder, and the body is filled with the filling is introduced into the conveying path of the rotary disk 12 and then the cap 2 in the final step to be discharged through the capsule discharge unit.

In the filling injector, a powder filling material is supplied from the hopper 21 through the screw feeder 22 and stored in the housing 23.

The housing 23 is provided with a plurality of compression molding holes at equal intervals on the bottom thereof, and includes a rotary disk driven in an index manner, and charging pins 25 driven by a cam driving method or a servo motor SM on an upper side thereof. The filling of the powder mounted in the rotary disk is sequentially formed in the compression molding holes by using compression elements 26 which are arranged in multi-steps from the beginning to the final step.

Then, the filling of the green compact is introduced into the body supplied through the capsule supply unit 10 described above using a discharge element to be discharged.

The limit value of the average mass value and the limit value of the compressive force may be derived through experiments, respectively, and the limit value may be stored in the controller 600.

If the average mass value and / or the compressive force is out of the limit value (S7), the compressive force at the time of forming the green compact is corrected and returned to the capsule feeding step S1.

The drug is made again according to the corrected compression force to measure the mass and compression force of the drug.

That is, the filling step S3, the measuring step S5, and the correction step are cycled until the average mass value and / or the compressive force do not deviate from the limit value.
