A pneumatic apparatus for withdrawing goods from defective blister packages on a blister packaging machine and comprising a pair of spaced-apart and laterally shiftable vacuum heads reciprocally mounted above the carrier strip between the detection station and the sealing station of the blister pack

A pneumatic apparatus for withdrawing goods from defective blister packages on a blister packaging machine and comprising a pair of spaced-apart and laterally shiftable vacuum heads 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 comprises a plurality of suction elements depending from the bottom thereof which are adapted to selectively engage a predetermined plurality of goods on the carrier strip. Control means are operatively associated with pneumatic means adapted for sequentially causing each of said pair of spaced-apart heads when operatively positioned over the carrier strip to descend, pneumatically engage a selected portion of the plurality of goods, return to the elevated first position, and laterally shift to the offset inoperative position to release the plurality of goods into a goods collection bin. Next, the other head which is now in position over a new intermittently advanced segment of the carrier strip repeats the same cycle as the first vacuum head and releases the goods collected thereby into a goods collection bin on the other side of the carrier strip.

A blister packaging process providing for the recovery and recycling of goods from defective blister packages, comprising the steps of: (a) forming one or more blisters across the width of a progressively advancing carrier strip; (b) filling said one or more blisters in said carrier strip with goods which are to be blister packaged; (c) sensing the presence of empty blisters in said carrier strip; (d) providing one or more laterally shiftable heads mounted above said carrier strip so as to move from a position in vertical registration with said carrier strip to a position laterally offset from said carrier strip, wherein said head comprises one or more engagement elements depending from the bottom thereof and adapted to engage goods on said carrier strip; (e) providing control means for causing said head when positioned over said carrier strip to descend and engage one or more defective blister package sections of said goods with said one or more engagement elements thereof, raise upwardly and shift to said laterally offset position, and release said goods into a collection container; (f) sealing said blisters of said carrier strip with an overlaying strip; (g) forming blister packages by separating a plurality of blister package sections containing one or more blisters from said carrier strip; and (h) sorting defective blister packages from which the goods have been removed from non-defective blister packages.
