ABSTRACT:
A rotary transfer mechanism for transferring flat sleeve cartons (20) from a magazine (22) to a receiving station (23) on a conveyor (24), with opening of the cartons ready to receive end-loaded product, is characterized in that the path of suction cups (32) for holding the cartons during transfer is basically determined by a continuous stationary cam track (34) permanently engaged by a cam follower (37) on a gear segment (35) pivotally mounted on carrier means (29) rotatable by a drive shaft (26), the suction cups (32) being carried by a support shaft (30) rotatable on the carrier means and coaxial with a pinion (38) meshing with the gear segment. (35), and the support shaft being connected to a bracket (48) carrying a manifold (47) for the suction cups (32) by a crank arm (53), which is connected by a link arm (54) to a rocker arm (55) freely rotatable on the drive shaft (26). A servomotor (27) programmed by a computer (not shown) drives the drive shaft (26) through a gearbox (28) to vary the speed of the suction cups (32), especially when passing through the delivery station (23) to effect opening of the cartons (20) by movement relative to flights (64) on the conveyor (24).
