Inspection device for the quality control of rod-shaped articles

An inspection device for the quality control of rod-shaped articles, the device comprising:

• a drum 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;
• a compressed air system aligned with the seat of the plurality;
• an actuator adapted to activate the compressed air system to blow air when the rod-shaped article is located in the seat to push the rod-shaped article inside the coil.

An inspection device comprising:

• a first drum defining a first outer surface and including a first plurality of seats, each seat of the first plurality adapted to receive a rod-shaped article;
• a first inductive sensor positioned at a seat of the first plurality, the first inductive sensor including a first coil defining an inner volume large enough to receive therein a first end of the rod-shaped article, the first inductive sensor being adapted to sense a characteristic of a first susceptor in the rod-shaped article;
• wherein the first coil includes a first semi-coil and a second semi-coil, the first semi-coil and 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 first 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 vice-versa;
• the first semi-coil being located below the first outer surface of the first drum and the second semi-coil being located above the first outer surface of the first drum;
• a first actuator adapted to move the first semi-coil and the second semi-coil of the first coil from the first operative position to the second operative position and vice-versa in the first drum;
• a second drum defining a second outer surface and including a second plurality of seats, each seat of the second plurality being adapted to receive a rod-shaped article;
• a second inductive sensor located at a seat of the second plurality, the second inductive sensor including a second coil defining an inner volume large enough to receive therein a second end of the rod-shaped article, the second inductive sensor being adapted to sense a characteristic of a second susceptor in the rod-shaped article;
• wherein the second coil includes a first semi-coil and a second semi-coil, the first semi-coil and 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 second 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 vice-versa;
• the first semi-coil of the second coil being located below the second outer surface and the second semi-coil of the second coil being located above the second outer surface;
• a second actuator adapted to move the first semi-coil and the second semi-coil of the second coil from the first operative position to the second operative position and vice-versa in the second drum;
• the first drum and the second drum being substantially tangent so as to allow a transfer of the rod-shaped article from the first drum to the second drum.

• a first actuator adapted to activate the first compressed air system to blow air when the rod-shaped article is located in the seat of the first plurality to push the rod-shaped article inside the first coil;
• a second drum including a second plurality of seats, each seat of the second plurality adapted to receive a rod-shaped article;
• a second inductive sensor positioned at a seat of the second plurality, the second inductive sensor including a second coil defining an inner volume large enough to receive therein a second end of the rod-shaped article, the second inductive sensor being adapted to sense a characteristic of a second susceptor in the rod-shaped article;
• a second compressed air system aligned with the seat of the second plurality;
• a second actuator adapted to activate the second compressed air system to blow air when the rod-shaped article is located in the seat of the second plurality to push the rod-shaped article inside the second coil of the second drum;
• the first drum and the second drum being substantially tangent so as to allow a transfer of the rod-shaped article from the first drum to the second drum.
