In a method for optoelectronically inspecting pharmaceutical capsules () in a capsule filling machine (), the pharmaceutical capsules () are fed in single file from a station () where the capsules () are made to a capsule () outfeed portion () of the machine () along a defined feed path (P) passing through an inspection station (). In the inspection station (), each pharmaceutical capsule () passes through an electromagnetic field created by coherent, polarised light radiation.

Method for optoelectronically inspecting pharmaceutical articles

A unit () for checking the dosing of pharmaceutical material (M) in a capsule filling machine () for the production of capsules (CF) of the type with a capsule lid (C) and a capsule body (F), the machine () comprising a fixed structure () fitted with a rotary drum () for supporting a plurality of capsules (CF) on its edge, opening each capsule (CF) by separating the capsule lid (C) from the capsule body (F), filling the capsule body (F) with a dose of material (M), then closing the capsule body (F) again with the relative capsule lid (C); the rotary drum () having a tank () containing the pharmaceutical material (M) and supporting a plurality of doser elements (), each comprising at least one piston () sliding inside a hollow cylinder () to pick up and compress a dose (DS) of material (M) from the tank () and discharge it into a capsule body (F) of a capsule (CF). The unit () comprises sensor means () attached to each piston () for detecting a piston () thrust value (V; V) on the dose (DS) and transmitter means () connected to the sensor means () for transmitting the value (V; V) to a receiver element () by the telemetric transmission of a relative signal (S; S), said receiver element () being fixed on the machine () in at least one zone (P; P) of the fixed structure (). Power supply means () are also provided for cyclically activating the sensor means () and the transmitter means () during drum () rotation.
