<p>A pneumatic apparatus (10) for withdrawing goods from a defective blister package on a blister packaging machine and comprising a pair of spaced-apart and laterally shiftable vacuum heads (20) reciprocally mounted above the carrier strip between the detection station and the sealing station of the blister packaging machine so that when one head is in vertical registration with the carrier strip, the other head is laterally offset from the carrier strip. Each vacuum head (20) comprises a plurality of suction elements (20B) depending from the bottom thereof which are adapted to selectively engage a predetermined plurality of goods on the carrier strip. Control means (PLC) are operatively associated with pneumatic means (20A, 24) adapted for sequentially causing each of the pairs of spaced-apart heads, in turn, to be operatively positioned over the carrier strip, descend and pneumatically engage a selected portion of the plurality of goods, return to the elevated position, and laterally shift to be offset position to release the plurality of goods into one or the other of the goods collection bins (22).</p> |
