Patent ID: 8584615

Claim:
A spray assembly for a machine structured to apply a coating to a plurality of can ends, the spray assembly comprising: a power source; a motion control mechanism; and at least one spray head comprising: a mounting member, a pivot member including a first end movably coupled to the mounting member, and a second end disposed opposite and distal from the first end, a gun assembly comprising a plurality of spray guns coupled to the pivot member proximate the second end, and a transfer mechanism for transferring a predetermined motion that is induced by the motion control mechanism from the motion control mechanism to the pivot member, wherein each of the spray guns is structured to apply the coating to the can ends in accordance with said predetermined motion; wherein the pivot member is a pivotal shaft; wherein the pivotal shaft has a longitudinal axis of rotation; wherein the second end of the pivotal shaft includes a first mounting portion and a second mounting portion disposed opposite the first mounting portion; wherein said plurality of spray guns is a first spray gun coupled to the first mounting portion and a second spray gun coupled to the second mounting portion; wherein the gun assembly further comprises a number of spacers; wherein each of the spacers is disposed between one of the first and second mounting portions and a corresponding one of the first and second spray guns, thereby offsetting said spray gun with respect to the longitudinal axis of rotation; wherein each of the first and second spray guns is structured to move in an arcuate path to coat a corresponding arcuate portion of the can ends; wherein each of the can ends has a diameter; and wherein the spacers are structured to adjust the size of the arcuate spray path of the spray guns to correspond to the diameter of the can ends.
