DUAL LANE CONVEYING APPARATUS

摘要

A dual lane board handling apparatus includes a first zone (1) including first and second parallel pairs of rails (R1-1,R1-2,R1-3,R1-4)(R2-1,R2-2,R2-3,R2-4) extending in a first direction; a second zone (2) including third and fourth parallel pairs of rails (R3-1,R3-2,R3-3,R3-4)(R4-1,R4-2,R4-3,R4-4) extending in the first direction; first tracks (110,111,112,113) 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 drive for (146) 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 it is in alignment with the fourth pair of rails and a second orientation wherein it is in alignment with the third pair of rails; a drive for moving the second pair of rails in the second direction; and belts (176) on the first, second, third, and fourth pairs of rails for conveying boards along the rails in the first direction.
