Product description

In the event of a short stop in the raw sorting plant, the buffer is used to temporarily receive and store the timber flow from the sawmill, so the mill won’t have to be stopped. Once the stoppage has been fixed, the buffer is emptied at the same time as the lumber flow from the saw-line is received and sorted.

  • Very high accessibility from the saw-line.
  • Careful handling of the timber.
  • Robust, tried and tested design solutions
  • Reliable technology since 2004.
  • Custom-designed with several alternative solution principles, but based on a common basic concept.
  • Fully-automatic control of reloading and emptying.

Function description

If, during on-going sawing, a stop in raw sorting occurs, the buffer automatically re-channels the timber flow so that it gets stored in different batches on different chain conveyors. As soon as the sorting restarts, the main flow is controlled from the sawmill back to the sorting plant, at the same time the temporarily stored timber is portioned back mixed with the main intake 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 fully automatic.
To prevent damage to the timber when it drops between two levels, the buffer is fitted with different methods for careful handling, such as the flap drop damper, and belt-cushioned transporters. In order to create an orderly and high bundle without damaging the timber, a buffer pocket is often used. The buffer pocket consists of two walls that form a V-shape, of which the one wall pneumatically folds down to enable the release of the timber when the correct level has been achieved.
