ABSTRACT:
A lumber end sealing machine involves a pass-through design utilizing a single exhaust system and the use of traveling and rotating sealer paint spray guns. An exhaust chamber is centered over the conveyor with spray guns located at both the conveyor entrance and exit openings of the exhaust chamber. The spray guns are formed to both transversely and rotatingly pass through an end face of the package of lumber which is stopped at the center of the exhaust system. The spray guns are supported on a vertical rod suspended from a carriage with transverse movement through the use of a pneumatic rodless piston and rotational movement of the spray guns by rotation of the vertical rod by means of a cam follower mechanism engaged with a curved profile bar. The actual spraying of the sealer paint occurs during only a portion of the passage of the spray guns across an end face, the spraying beginning and stopping with the spray guns still located to the inside of the vertical side edges of the end face and with the spraying being directed outwardly toward the vertical side edge of the end face so as to mask the sides of the package. An alternative configuration of the invention includes fixed spray means centrally located along the sides within the exhaust chamber so as to additionally spray sealer paint inwardly on the sides of the package as it passes through the chamber.
