Abstract: In a carton loading machine, there is provided a mechanism which will initially displace one row of cylindrical-shaped objects with respect to its adjacent row such that load items in one row are located in a staggered relationship with respect to the load items in the adjacent row. The load items are then displaced into the open end of a container. When the assembled load is substantially fully located within the container, the movement of one row is arrested while the movement of the other row continues until the items of the adjacent rows are arranged in a side-by-side relationship. This serves to permit the width of the accumulated load to be reduced until the load is substantially fully located in a carton and thereafter the load is rearranged to its maximum width to fit in a close fitting relationship within the carton.

Abstract: A load accumulator which has one or more stacking wheels mounted for high speed rotation is provided with an improved conveyor for conveying load items to the stacking wheel. The conveyor includes platforms that extend toward each stacking wheel in a plane located above the stacking wheel. An endless conveyor is mounted above the platforms and has a forward run that extends toward a discharge end from the platform which opens into a pocket of the transfer wheel. A plurality of load pushing fingers are mounted on the conveyor and project toward the platform. The fingers positively drive the load items along the platform and ensure that the load items are correctly positioned for entry into the pockets of the transfer wheel at high speed.

Abstract: A feeder mechanism for feeding load items in a predetermined spaced relationship into a loading station of a carton loading machine comprises at least two conveyors which move at different speeds along the same path and elevator ramps on each of the conveyors. The primary conveyor has a forward run mounted for movement at a first predetermined speed in a forward direction. The forward run has an input end for receiving load items and it extends forwardly from the input end into a spacing station. The secondary conveyor has a forward run mounted for movement at a second speed in the forward direction which is faster than the first speed. At least a portion of the forward run of the second conveyor is located adjacent and coextensive with a portion of the forward run of the primary conveyor in the spacing station.

Abstract: A packaging machine has a loading station in which load items are loaded into a container. A load transport conveyor extends through the loading station. A load supporting compartment is formed on the conveyor. The compartment has a discharge passage opening from the trailing end thereof and a guide at the trailing end for guiding a load item toward the discharge passage. A receiver is located in said loading station for receiving a load item discharged from the load supporting compartment. A stop is located in the loading station and extends into the path upstream of said receiver whereby the movement of a load item carried by the load supporting compartment along the path is arrested by contact with said stop means and continued movement of the load transporting conveyor causes the load item to engage the guide to be directed thereby through the discharge passage into the receiver.

The bag loading machine includes a bag transfer platform which is supported to articulate about a lever as it is raised and lowered so as to move the platform between a bag receiving position for receiving a bag from a bag making machine, a bag loading position for receiving a load and a bag discharge position from which the loaded bag is discharged.

Abstract: A load orienting receptacle for a carton loading machine for use in loading lightbulbs into an open end of a carton. The receptacle has a trough in which a slipway extends to an open discharge end. The slipway has an open upper end for admitting a lightbulb to a load orienting portion thereof spaced inwardly from the discharge end. The load orienting portion has opposite sides which converge downwardly to form a downwardly directed laterally inclined chute. The opposite sides are spaced from one another a sufficient distance to support the bulbous end of a light bulb above the bottom of the trough while permitting the narrow end thereof to be laterally deflected as it passes downwardly along the chute to come to rest in the trough thereby to laterally offset the narrow end with respect to the bulbous end of the bulb prior to discharge through the open discharge end of the trough.
