Abstract:
An infeed conveyor for feeding wood of a variety of types and lengths to a debarking drum which can be adjusted in height so as to optimize the infeed conditions as desired. The conveying apparatus is adapted to convey tree-length logs to a debarking drum. To that end, the system includes a foundation and a conveyor disposed vertically above the foundation. The conveyor has an inlet end at which logs to be debarked are loaded and an outlet end adjacent the debarking drum. The conveyor is mounted to the foundation so that the height of the inlet end and/or the outlet end can be selectively varied with respect to the foundation assembly. The conveyor is then held at least temporarily held at a selected height and/or inclination.
Abstract:
An improvement in a debarking machine of the type including an annular frame, a plurality of debarking tools mounted in annularly spaced relation within the annular frame for rotation together about the axis of the annular frame and for movement toward and away from each other, infeed and outfeed mechanisms for feeding logs through the annular frame so that the tools will engage the exterior periphery of the successive logs and strip the bark therefrom during their movement through the annular frame. The infeed mechanism includes three driven infeed spiked rolls arranged so that their spiked peripheries normally engage the exterior periphery of the log in centered relation and move the same axially through the annular frame for debarking by the tools. Each of the spiked rolls includes a cylinder and a multiplicity of spikes extending radially outwardly therefrom. The improvement comprises providing at least one of the infeed rolls with an elongated member (preferably three) secured to and extending substantially transversely across the exterior periphery of the cylinder thereof and defining a substantially continuous log penetrating surface disposed generally in the plane of the outer ends of said spikes. The log penetrating surface of each elongated member is configured to penetrate a log engaged thereby to an extent less than the penetration of the log by the spikes of the associated roll so that another roll cooperatively engaging the log serves to effect a transverse centering movement of the log along the elongated member while engaged thereby.
