Abstract: A debarking machine having a plurality of debarking tools spaced circumferentially around a rotor. The debarking tools are movable independently between radially inward positions and dilated positions. Movement of the debarking tools is caused by hydraulic rotary actuators, hydraulic fluid pressure being supplied to the actuators independent hydraulic accumulators, a pair of hydraulic accumulators being provided for each rotary actuator.

Abstract: A cutting tool assembly for a log debarker. A cutting tool is provided having an elongated leading cutting edge and a key member. The key member fits into the load carrying slot portion of the head of the tool shaft, and the tool is then secured to the tool shaft head with a plurality of retainer bolts. The tool shaft head is machined at an angle of generally five degrees relative to the axis of an incoming log so as to slant the orientation of the tool and its leading edge. Thus, an incoming log will impact initially a central location of the tool and not its full length. A tensioning device places the tool shaft in tension about a pivot axis and the outermost tip of the tool continually points towards the center line of an incoming log as the tool shaft pivots about this pivot axis. Every other tool is extended a slight distance further towards the incoming log than the adjacent tools by an extension spacer or washer to further reduce the shock loading previously encountered.
Abstract translation: 用于对数剥皮机的切割工具组件。 提供了具有细长的前切割刃和关键部件的切割工具。 钥匙部件装配到工具轴的头部的承载槽部分中，然后用多个保持器螺栓将工具固定到工具轴头上。 工具轴头相对于输入原木的轴线大致为五度的角度加工，以便倾斜工具及其前缘的方位。 因此，输入的日志将最初将影响工具的中心位置，而不是其全长。 张紧装置使工具轴在枢转轴线处张紧，并且当工具轴围绕该枢转轴线枢转时，工具的最外端部连续地指向输入原木的中心线。 每个其他工具通过延伸垫片或垫圈进一步向着相对的工具进一步延伸到进入的原木，以进一步减少以前遇到的冲击载荷。

Abstract: A log debarker having a frame, a stator supported by the frame, a rotor journaled in the stator for rotation about a longitudinal axis of the rotor, a rotating mechanism for rotating the rotor about the longitudinal axis, and a plurality of debarking tools attached to the rotor. An infeed mechanism positioned on the infeed end of the stator feeds logs axially into the rotor. The infeed mechanism includes a first feed roll, a second feed roll, and a third feed roll, all of which are disposed in a triangular relationship around the longitudinal axis. A first rigid link connects the first and second feed rolls, and a second rigid link connects the second and third feed rolls. An air-operated tensioning mechanism is provided having an air cylinder connected at one end to the second feed roll for adjusting the position of the infeed means relative to the longitudinal axis. The air cylinder when energized causes the first, second, and third feed rolls to move together relative to the longitudinal axis. The air cylinder includes at least one air inlet, an air outlet with a quick release valve, a sliding piston, and a solenoid valve connected to the air inlet for inputting air into the air cylinder thereby pushing the sliding piston out and opening the infeed mechanism. A limited pressure cushion on both sides of the piston of the air cylinder prevents the piston from slapping one end or the other as it changes directions.

Abstract: An apparatus for separating bark, such as birchbark, from timber during conveyance of the timber has a conveyor for advancing logs leaving a stripping drum. To achieve an effective separation of bark, rollers conveying the logs form a bark separating unit, where successive ones of the rollers are arranged at two levels, the rollers at the upper level being provided with spikes for scraping or detaching the bark, and the rollers on the lower level being substantially smooth-surfaced.

Abstract: A log-feed apparatus used in a log-feed assembly, where the assembly functions to advance a log along a transport axis in a log-debarking system. An elongated arm in the apparatus is mounted at an inner end for swinging of its outer end toward and away from the transport axis. A spiked feed roll, journaled on the outer arm end for powered rotation about the arm's long axis, is carried on the outer end of a shaft which is journaled on the arm by a pair of axially spaced bearings. A gear reducer mounted on the arm, intermediate the arm ends, is driven by an arm-mounted motor through a flexible belt drive. The output of the gear reducer is drivingly connected to the inner end of the shaft by a torsionally flexible rotary coupling. The shaft and bearings journaling the feed roll on the arm act to isolate all components of the drive train which extend between the shaft and motor from substantially all but torsional load transmitted by the feed roll during operation of the log-feed assembly.

Abstract: An air-seal cooling fin system in a log debarker of the type having a frame, a ring mounted for rotation on the frame, and air-pressure actuated debarking arms carried on the ring. Pressurized air is supplied to the arms through a rotary air seal composed of a stationary seal portion joined to the frame and a rotatable seal portion joined to the ring including a pair of spaced annular elements disposed on axially opposed sides of the stationary portion. Arranged on each of the annular elements in the rotatable seal portion is a circular array of angularly spaced fins. These fins act to radiate heat generated in the seal during debarker operation and interact with a circular array of fins carried on the stationary portion to create cooling air turbulence in the region of the seal.
