A method and a device for detection and removal of one or more misplaced boards ( 6 ) on an elevator for the separation of boards ( 6 ). The elevator comprises a frame ( 1 ) that supports carrier chains ( 2 ) that run over pulley wheels ( 3, 4 ) and demonstrate carriers ( 2.1 ) on which boards ( 6 ) are lifted. The elevator comprises removal devices ( 5.3, 5.4 ) for misplaced boards ( 6 ). Removal of two or more boards that have been lifted together on one row of equivalently placed carriers ( 2.1 ) is achieved with the aid of at least one laser-light detector ( 10.3, 10.4 ). Laser light is directed towards the long sides of the boards ( 6 ) and reflected laser light is received in the relevant detector ( 10.3, 10.4 ). The signals from each detector ( 10.3, 10.4 ) are processed in a computer and the boards ( 6 ) removed from the elevator with the aid of a removal device ( 5.3, 5.4 ) if misplaced boards ( 6 ) are registered by the computer. |
