ABSTRACT:
According to a method for selecting and feeding articles to blisters or containers, a first hopper filled with unselected articles feeds a second main hopper with selected size-matching articles, by means of a tapered inlet section. Size non-matching articles get jammed and stopped within the tapered inlet sections and are removed by means of a shutter hinged to each inlet section. A sensor detects when the flow of size-matching articles is interrupted. According to a second embodiment the inlet sections are replaced by swinging tubular portions. The shutters and tubular portions can be operated cyclically, thus avoiding the need for the sensor. An apparatus is also described for carrying out the method.
