Abstract:
A dual lane board handling apparatus, comprising:a first zone including first and second parallel pairs of rails extending in a first direction; a second zone including third and fourth parallel pairs of rails extending in the first direction; first tracks supporting the first and second pairs of rails so that the first and second pairs of rails can move on the first tracks in a second direction perpendicular to the first direction; a first drive mechanism for moving the first pair of rails on the first tracks in the second direction such that the first pair of rails can be selectively moved between a first orientation wherein the first pair of rails is in alignment with the fourth pair of rails and a second orientation wherein the first pair of rails is in alignment with the third pair of rails; a second drive mechanism for moving the second pair of rails in the second direction; and a conveyor on each of the first, second, third, and fourth pairs of rails for conveying boards along the rails in the first direction.
