Wood Processing System With 360-Degree Rotating Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood processing systems require extensive travel movements and reclamping or overturning to access all sides of a workpiece, leading to inefficiencies and increased control expenses.
Innovation Solution
The wood processing system allows for 360° rotation of the processing unit around a second axis on a carrier, enabling unrestricted access to all workpiece surfaces without overturning, with a transport device using motorized slides and clamping jaws for efficient movement and clamping, and a motor spindle capable of three-axis rotation to process all six sides efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arm is limited to 180° rotation around the second axis, then the device complexity is reduced, but the accessibility to all surfaces of the workpiece is restricted requiring overturning or reclamping
Solution Approach 1:
The arm is designed to rotate dynamically by 360° around the second axis (B axis) instead of being limited to 180°, enabling the processing unit to access all surfaces of the workpiece including rear and front faces without overturning or reclamping operations
2Productivity
If the processing unit requires extensive travel movements to access all sides, then the device complexity is reduced, but the productivity decreases due to more movements and reclamping processes
Solution Approach 1:
The processing unit is mounted on an arm that can rotate by 360° around the second axis, allowing rapid repositioning to access all six sides of the workpiece without requiring extensive linear travel movements or multiple reclamping operations, thereby significantly improving processing productivity
3Ease of operation
If the arm is arranged with offset support part, then the ease of operation is improved by simplifying control and programming, but the manufacturing precision of tool alignment may be affected
Solution Approach 1:
The support part of the arm is intentionally offset relative to the second axis of rotation, creating an asymmetric arrangement that simplifies the control system and programming by aligning the tool axis with the rotation axis plane, while the precision is maintained through the coordinated three-axis rotation capability of the processing unit

AI summary
A wood processing system has a processing assembly containing a carrier movable in a second linear axis at right angles to a first linear axis and a third linear axis perpendicular to it, on which a processing unit designed as a motor spindle to accommodate at least one rotationally driven processing tool is arranged to pivot around three axes of rotation. The processing unit is arranged to pivot around a third axis of rotation spaced from the first axis of rotation on the free end of an arm pivotable on the carrier around a first axis of rotation and a second axis of rotation perpendicular to the first axis of rotation. The arm is arranged rotatable by 360° around the second axis of rotation on a front carrier part, which is arranged to rotate around the first axis of rotation perpendicular to the first linear axis on a front end face of the carrier.
