Unscrambler

If a green sorting stop occurs when sawing is in progress, the the lumber is automatically redirected to the Unscrambler Buffer for storage as a bundle on a chain conveyor. When the Unscrambler Buffer receives lumber from the saw it is in its horizontal position. As soon as sorting restarts, the main flow is automatically redirected from the saw to the sorting plant, and the Unscrambler Buffer is rotated back down to its conventional position. The elevator lifts and sorts lumber into a collection bin and carries the lumber for onward transverse transport. The temporarily stored lumber is apportioned back and mixed into the main flow. This is achieved by increasing the speed in the sorting plant until the buffer is empty. The buffer function with both buffering and emptying together with the automatic speed control of the sorting plant is semi-automatic.
