摘要： A device is disclosed for separating hard objects, such as stones, from a stream of wood in an apparatus for conveying or manipulating logs or blocks of wood including a conveyor section. The device includes a transducer disposed in a location suited for the detection of vibration. The transducer registers acoustic vibrations and is connected to a control unit by means of which hard objects conveyed along with the wood stream can be detected on the basis of the vibration signals they generate. The control unit is also used to control an exit gear incorporated in the conveyor section, so that hard objects which are detected will fall down from the stream of wood passing through the apparatus. The invention eliminates the need to build water-operated stone catchers as conventionally used for the removal of stones.

摘要： A debarking mechanism including of rotatable debarking shafts extending parallel to an advancing direction (A) of the logs to be fed therethrough, which are provided with teeth extending beyond the circumferential surface of the shaft. At least the uppermost debarking shaft is moved sideways towards the inner part of the debarking mechanism in such a way that each debarking shaft directs an impact effect on logs colliding with it and moved by the debarking shafts located in a lower position. The circumferential speed of the debarking shaft is selected to be the greater the higher the debarking shaft is positioned. A free passage is arranged for the bark passing over the debarking shaft.

摘要： The invention relates to a debarking mechanism (1) for the decortication or pretreatment of logs (2) for separately performed final debarking and for the discharge of at least some of the bark removed from a wood stream passing through the debarking mechanism, the said debarking mechanism comprising a number of rotatable debarking shafts (3, 3′) extending parallel to an advancing direction (A) of the logs (2) to be fed therethrough, which are provided with a number of teeth (4) extending beyond the circumferential surface of the shaft (3, 3′). The debarking shafts (3, 3′) are arranged relative to each other in such a way that the logs (2) being processed perform a rotary motion (C) in the debarking mechanism, in which motion the logs (2) are forced in their turn, by the effect of the rotary motion (5) of the debarking shafts (3, 3′), into the upper position, from which they roll down into the lower position on top of the other logs (2) in the debarking machine (1). At least the uppermost debarking shaft (3′), is moved sideways towards the inner part (6) of the debarking mechanism (1) in such a way that the said debarking shaft directs an impact effect on logs (2) colliding with it and moved by the debarking shafts (3) located in a lower position, due to the effect of which the direction of movement of the logs (2) having collided with the said debarking shaft will change in such a way that when dividing the movement into a horizontal and a vertical component, the horizontal component of the movement will point towards the inner part (6) of the debarking mechanism (1). The circumferential speed of the debarking shaft is selected to be the greater the higher the debarking shaft (3, 3′) is positioned. A free passage (7) is arranged for the bark passing over the debarking shaft (3′).
