ABSTRACT:
A take-out mechanism for removing sets of blow molded bottles from a blow mold includes a rotary turret, a take-away conveyor and a drive for moving the turret between the blow mold and the take-away conveyor. The turret has a number of sides with a plurality of vacuum plugs extending from each side. The drive moves the turret toward the mold to extend a set of plugs on one side of the turret into mold cavities and vacuum-capture bottles molded in the cavities. After opening of the mold, the turret is lowered and rotated 90.degree. to position the vacuum-held bottles at the infeed end of the take-away conveyor. Rotation of the turret positions a second set of plugs facing a second mold moved to the take-out position. Subsequent rapid retraction of the turret moves the set of removed bottles into the take-away conveyor and powers the conveyor to receive the bottles while maintaining orientation between individual bottles. The turret is raised to remove the plugs from the bottles held in the conveyor and then rapidly extended back to the next mold to position the second set of plugs in bottles in the mold.
