Cigarette package inspection indexing wheel

In a cigarette packaging machine wherein finished cigarette packages are advanced along a first predetermined path, inserted into one of many receptacles in a rotatable turret where they are moved along a second path to a transfer position where they are pushed from the turret to a third predetermined path, the improvement comprising:

• (a) a rotatable indexing wheel having spaced cigarette package receiving pockets, the pockets being moved into alignment with a given position of the second path between the receiving and the transfer positions;
• (b) means for guiding cigarette packages into a predetermined pocket;
• (c) means for rotating the indexing wheel so that the packages in the pockets are advanced sequentially to each of two vision inspection stations;
• (d) means for restraining the cigarette packages against the effects of centrifugal force while they are being indexed by the wheel;
• (e) means for inspecting the cigarette packages at the two vision stations, on at least three package surfaces of each cigarette package, to determine those packages which are defective;
• (f) means for removing defective packages from the indexing wheel, to prevent them from re-entering the finished product flow;
• and
• (g) means for returning those cigarette packages which have successfully passed inspection, to a turret receptacle at the given position of the second path so that the cigarette packages are in the same orientation and sequence as they were removed from the turret.
