| 摘要 |
The board metering device of the present invention is mountable beneath a board conveyor, and includes an upstream gate and a downstream gate. The downstream gate is generally parallel to and spaced apart a first distance from the upstream gate. The upstream gate cooperates with a first actuator for vertical actuation of the upstream gate between an upstream elevated position and an upstream lowered position. The downstream gate cooperates with a second actuator for vertical actuation of the downstream gate between a downstream elevated position and a downstream lowered position. When in the upstream and downstream elevated positions, respectively, the upstream and downstream gates intersect a board flow path so as to interrupt a downstream flow of boards along the board flow path on the board conveyor. |
