Abstract
The present invention relates to a phase shifting debarker. The shifting debarker generally comprises a phase shifting mechanism being powered by a main motor and being connected to an operative assembly by the mean of timing belts. The main motor is being configured to control, by the mean of a belt, the movement of the phase shifting mechanism which is being adapted to control the movement of the operative assembly by the mean of the timing belts. The operative assembly generally comprises an actuator ring and a main ring. The activation of the shifting mechanism creates a shift phase between the actuator ring and the main ring while rotating at the same speed.
Claims22
A phase shift log debarker, the debarker comprising:
- an operative assembly comprising:
- an aperture adapted to receive a log;
- a first ring rotatably mounted to a second ring about a common axis;
- tool arms adapted to move in and out of the aperture;
- a driver inducing rotation of the first ring;
- and
- a phase shifter driven by the driver and inducing rotation of the second ring, the phase shifter being adapted to shift a position of the second ring at a shift angle relative to the first ring, the shift angle being between a minimum angle and a maximum angle and being a function of a measured diameter of the log;
- wherein the shift of position of the second ring to the shift angle triggers the movement of the tool arms.
