  • Patent number: 6179004
    Abstract: A vacuum holder for use with an automated carton erecting and packing line and mountable on a rotary carton placer for removing cartons into which product is to be placed includes vacuum cup for removing a carton from a store of cartons. The cartons including a foldable flap. The vacuum holder includes a set of vacuum cups that will engage a flap and at an appropriate time in the carton erection sequence will be positively actuated under control of a power actuator to fold the flap to a desired position prior to depositing the carton on a conveyor line. A rotary manifold carries both vacuum for vacuum cups holding the carton, and fluid pressure for the power actuators to the rotating carton placer.

  • Patent number: 5579895
    Abstract: A crosspush conveyor moves cans laterally of a can conveyor into cartons that are also moving at the same speed as the can conveyor. The crosspush conveyor is mounted on a pair of sprockets that support roller chains to form two straight lengths, with the lengths being positioned at an angle relative to the direction of movement of the can conveyor. A plurality of paddles or pushers are mounted onto the chain conveyor and are pivotally mounted so that they can pivot away from a working position as they move through a selected portion of their path of travel. The paddles are supported in a working position on guide rails to hold the pusher members so that they will move cans laterally of the can conveyor on one side of the conveyor. The crosspush conveyor operates without a separate control cam for holding the crosspush members in position throughout the travel of the conveyor.

  • Patent number: 5456570
    Abstract: A rotary placer for picking, transferring and placing a carton from a stack of cartons or sleeves in a magazine to an assembly position. The rotary placer includes a frame driven for rotation about a first axis and supporting an arm having an inner end and an outer end. The outer end of the arm has vacuum cups for engaging and releasably retaining a carton for movement from the pick position to the place position. The arm is reciprocated from an extended position to a retracted position. The vacuum cups engage a carton when the arm is in the extended position and the arm retracts to remove the carton from the magazine and carry it toward the place position. The arm again is extended as it reaches the place position. A cam guide controls the movement of the vacuum cups so they move linearly away from a carton in the magazine.
