Log Debarker Tool Axial Bolt Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional debarking machines with ring rotors have difficulty in replacing and properly torquing blade tips due to bolt placement, making it hard to access and tighten without interference from adjacent tools, especially as tool weight increases, leading to inefficient and labor-intensive processes.
Innovation Solution
Designing a debarking tool with bolts oriented parallel to the log's axis of travel, allowing easy access and power-torquing of blade tips, featuring an elongate curved body with attachment holes for secure placement and removal of tips, enabling efficient replacement and proper torque application using an impact wrench.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bolts are positioned on the side of the blade perpendicular to the longitudinal axis of movement, then the blade tip can be secured to the tool body, but access to the bolts is difficult due to interference from adjacent tools
Solution Approach 1:
The patent repositions the bolts from a lateral orientation (perpendicular to log movement) to an axial orientation (parallel to log movement). This dimensional change in bolt placement allows operators to access bolts from the end of the tool rather than from the side, eliminating interference from adjacent tools and enabling easier tip replacement.
2Productivity
If hand-operated tools are used to remove and replace blade tips, then the process can be performed without specialized equipment, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
By reorienting the bolts axially, the patent enables the use of impact wrenches and other power tools that can be applied along the axis of the tool. This eliminates the need for hand-operated tools and manual loosening/tightening processes, significantly improving productivity while reducing labor intensity.
3Ease of operation
If the tension on the tools is released to move adjacent tools out of the way, then bolt access is possible, but the tool operation is disrupted and time is lost
Solution Approach 1:
The axial bolt configuration allows operators to access and service blade tips without releasing tool tension or moving adjacent tools. The bolts are positioned such that they can be reached from the end of the tool in the axial direction, maintaining continuous tool operation and eliminating productivity disruptions.
4Reliability
If proper torque cannot be applied to blade tips, then the tips may become loose or damaged during use, but specialized torque-applying equipment cannot be used due to bolt placement
Solution Approach 1:
By positioning bolts axially along the tool body, the patent enables the use of impact wrenches and torque-applying equipment. The axial orientation allows these tools to be applied directly to the bolts from the end of the tool, ensuring proper torque is achieved for secure tip attachment while maintaining ease of operation.

AI summary
A tool for a ring-rotor log debarker, including an elongate, curved body for being attached by one end to a ring rotor of a log debarker. At least one attachment hole extends through the curved body of the tool on a free end opposite the one end attached to the ring rotor, and communicates with the first and second upstream and downstream oriented surfaces. A tip is placed onto the free end of the tool body, and includes an attachment hole sized and positioned for alignment with the at least one attachment hole in the tool body and for receiving a bolt through the aligned attachment holes for securing the tip to the tool body.
