Inspection device for the quality control of rod-shaped articles

Abstract

The present invention relates to an inspection device for the quality control of rod-shaped articles, the device comprising: ⋅a drum () defining an outer surface () and including a plurality of seats (), each seat () of the plurality adapted to receive a rod-shaped article; ⋅an inductive sensor () located at a seat () of the plurality, the inductive sensor () including a coil () defining an inner volume () large enough to receive therein an end of the rod-shaped article, the inductive sensor () being adapted to sense a characteristic of a susceptor () in the rod-shaped article; ⋅wherein the coil () includes a first semi-coil and a second semi-coil, the first semi-coil and/or the second semi-coil being movable from a first operative position where the first semi-coil and the second semi-coil are in contact to each other forming the coil () where current can flow to a second operative position where the first semi-coil and the second semi-coil are separated from each other and no current can flow, and vice-versa; ⋅the first semi-coil being located below the outer surface () of the drum () and the second semi-coil being located above the outer surface () of the drum (); and ⋅an actuator () adapted to move the first semi-coil and the second semi-coil from the first operative position to the second operative position and vice-versa.
