Abstract
The present invention concerns a wood chips analyser. A sample of a load of chips is weighed, and then inserted into the analyser. A sifting drum sifts out any dust present in the sample. The chips are then spread out through the use of a spreader drum and two vibrating trays, which insure that the chips are oriented horizontally. The chips are then fed to a transparent conveyor. A pair of cameras are arranged about the conveyor, one camera facing each surface of the conveyor. The output of the cameras is sent to a controller, which makes a three-dimensional representation of each chip. Once the sample have been analysed, a report is generated according to modifiable criteria. A typical report will indicate the percentage of a category of chips. This information is then used by paper mills to treat the chips accordingly.
