Abstract
Embodiments provide a log positioning system configured to transport a log through one or more chipper/profiler modules to produce a cant with four chipped/profiled sides. In some embodiments, a log processing system may include an infeed, a positioning feed module downstream of the infeed, and one or more chipper/profiler modules disposed proximal to the positioning feed module. The positioning feed module may include a sharp chain coupled to one or more pairs of vertical positioning rolls. The positioning feed module may be selectively skewed, slewed, and/or tilted to match the vertical and angular orientation of the infeed.
Claims19
An apparatus for positioning a log, comprising:
- a sharp chain configured to convey the log in a direction of flow;
- a carriage coupled with the sharp chain, the carriage having a first portion and a second portion disposed on opposite sides of the sharp chain, one or both of the portions being selectively repositionable toward and away from the sharp chain;
- and
- a first and a second vertical feed roll rotatably coupled to the first and second portions of the carriage, respectively, and disposed on opposite sides of the sharp chain, wherein the first and second vertical feed rolls are repositionable toward and away from the sharp chain relative to the carriage, and
- wherein the carriage is configured to vertically reposition the sharp chain and the first and second vertical feed rolls in concert to thereby tilt the log while the log is being conveyed on the sharp chain and engaged by one or both of the first and second vertical feed rolls.
