ABSTRACT:
This relates to a transfer mechanism for transferring cartons from a magazine for such cartons. The mechanism includes first and second plates which are joined together for rotation in unison about a fixed shaft. The second plate has pivotally connected thereto a generally radially extending member to which there are connected parallel links which, in turn, are pivotally connected to a carrier in the form of a link parallel to the member and the carrier in turn carries a pair of suction type pickup heads. One of the parallel links extends beyond the other from the carrier and carries a cam follower which is engaged with a cam that is fixedly connected to the first plate for rotation therewith. The fixed shaft also carries a fixed gear which is meshed with a gear which is rotatably mounted on the first plate and which carries an eccentric pin engaged in a slot in the radially extending member to rock the same about its pivot.
