Abstract

A storage and dispensing station for a blister packaging machine for drug portions includes a base electrically coupled to the blister packaging machine and configured to dissipate an electrical charge to the blister packaging machine. A storage container is disposed on the base and includes a housing defining a receiving chamber for drug portions, a cylindrical receiving chamber and a bottom surface. A singulating device is rotatably disposed in the cylindrical receiving chamber and has multiple channels extending along the singulating device and parallel with a rotational axis of the singulating device. The singulating device also includes an electrically conductive coupling and a drive for rotating the singulating device. The singulating device is electrically conductive at least at an outer surface of the singulating device, and the outer surface comes into contact with drug portions. A conductor device provides an electrically conductive coupling between the outer surface and an electrical contact.
