Abstract
A capsule filling and capping machine including a testing apparatus for ascertaining the presence of capsule pieces (bottom and cap) in the conveyor apparatus. The conveyor apparatus includes receptacles into which the capsules are tightly inserted. A test head, with chambers disposed in it that communicate with a source of negative pressure or overpressure, respectively, via a throttle is brought into contact with the receptacles, and the pressure of the chambers is monitored by pressure sensors. The output of piezorestrictive pressure sensors is evaluated electronically and processed further into signals to prevent capsules from being filled, to reject defective capsules, or to stop the machine if there is a problem related to one of the capsules.
