METHOD FOR MEASURING WEIGHT OF MEDICINE AND MEDICINE MEASURING MACHINE

摘要

PROBLEM TO BE SOLVED: To measure a weight of medicine by directly determining masses of numerous kinds of medicine and calibrating a sensor as functions of the masses of the numerous kinds of medicine. ;SOLUTION: A capsule 2b filled with medicine is sent at a measuring unit 4 output point to a weight measuring unit 20 by a drum 7. A drum 46 is in contact with the drum 7 and receives the filled capsule by using suction on an external side face 46a. The weight measuring unit 20 includes a weight measuring station 49 for receiving a precision balance 50. The balance 50 is connected to a CPU 21, the capsules 2b filled with medicine are successively removed from the drum 46, and supply of the capsules 25 to be sent to the balance 50 is received. The weight measuring unit 20 includes a capacitive sensor 59 which is connected to the CPU 21. The capacitive sensor 59 includes a movable armature and reads not only influence by a dielectric constant of the capsule but also influence by a dielectric constant of the medicine when it detects the mass of the capsule 25 filled with medicine. Thus errors can be reduced, and reliable processing is possible.;COPYRIGHT: (C)1999,JPO
