摘要： A lathe cutter and chip fan is described in which an annular frame includes a rotary portion that is driven to rotate about an axis. The rotary portion is annular, forming a workpiece receiving opening. A cutter is mounted on the rotary portion and projects into the workpiece receiving opening. The cutter rotates with the rotary portion to cut material from a workpiece positioned within the workpiece opening. A housing forms a compartment about the rotary portion and cutter, with a central housing opening substantially aligned with the workpiece receiving opening. A chip discharge openly communicates with the compartment and is situated substantially tangentially with respect to a rotational path of the cutter. A plurality of impellers are mounted to the rotary portion for rotation therewith. The impellers are configured to produce an airflow through the housing with intake air entering through the central housing opening and discharging through the chip discharge, whereby chips of workpiece material removed from the workpiece by the cutter may be discharged in the airflow through the chip discharge.

摘要： The present invention relates to a phase shifting debarker comprising crank arm mechanisms. The shifting debarker comprises a phase shifting mechanism powered by a main motor and connected to an operative assembly by the mean of timing belts. The main motor is configured to control, by means of a belt, the movement of the phase shifting mechanism which is adapted to control the movement of the operative assembly by means 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. The shift phase creates pressure from the rings to a crank arm mechanism, the crank arm mechanism transmitting said pressure to a pressure control system that finally transmits it to the operative assembly arms for debarking.

摘要： In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.

摘要： An arcuate debarking tool for ring rotor debarking machines used in timber processing. The tool comprises an elongated, arcuate body having an outer end that removably mounts a cutting element, and an inner arbored end adapted to be coupled through a mandrel shaft or the like to a ring rotor. A curved, thread-like leading edge first contacts logs that are transmitted axially through the revolving apparatus, and deflects the tools radially outwardly until the log is surrounded by the revolving ring of debarking tools. A companion, spaced apart exit edge is angularly defined in the frame. It functions in a thread-like manner to slowly unengage the rotating tools from the longitudinally traveling, debarked log. The curved exiting edge threadably revolves about the log circumference and slowly transfers the only remaining contact point between the withdrawing log and the revolving tool to an inward position whereby the tool is slowly, rather than suddenly, allowed to radially retract.

摘要： The present invention is a debarking ring apparatus to prevent operational downtime of logs debarking by having two debarking rings placed on the same vertical plan, perpendicular to the flow of incoming and outgoing logs, and parallel to each other. Only one ring may be operational at a time. As such, maintenance may be done on one of the rings while the other is in operation. Debarking rings may have varying sizes and shapes independent from each other. Each debarking ring may further have its own frame, actuator and control and motorization modules. A sliding system, supported by a frame, may further direct the lateral displacement of both rings. Also presented is a method of processing logs through the debarking ring apparatus.

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′).

摘要： An apparatus and method for machining the surface of logs, in which the log is longitudinally advanced through an opening provided in a rotor disc and the surface of the log is machined by rotatable cutting heads mounted on respective supporting arms pivotably connected to the rotatable disc and rotating therewith around the logs. The cutting heads are rotated around respective axes of rotation, while concurrently the cutting heads rotate with the rotor disc around the log such that the net rotational speed of the cutting heads at the surface of the log is the sum of the speed of rotation produced by the rotatable disc and the speed of rotation of the cutting heads around their respective axes. In the course of machining the logs, the speed of rotation of the rotor disc is varied as a function of conditions at the surface of the log and the rotational speed of the cutting heads around their axes is varied in relation to the rotational speed of the rotor disc to maintain a substantially constant net rotational speed of the cutting heads at the surface of the log.
