| 摘要 |
The invention concerns a board turner (1, 31) for use on a conveyor (3) f or transporting large volumes of boards. The conveyor (3) defines a plane for carrying boards (14) and the board turner (1, 31) has a rotation unit (4) and a gripping unit (7) mounted on the rotation unit (4). The gripping unit (7) has an open position and a closed position and is switchable between these positions in response to a signal from a sensor. In the open position, the gripping unit (7) rotates past the carrying plane without making contact with the synchronously arriving board (14). A signal from the sensor switches the gripping unit (7) between the open position and the closed position while th e gripping unit (7) grips two opposite surfaces of a sideways extending part of the board (1 4) and continues to rotate above the belt conveyor (3) in order to turn the board (14) in this way.
