Tool Arrangement for Wood Panel Side Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing the side surfaces of wood-based panels require alignment with a target structure, necessitating reconfiguration for each panel, which is inefficient and interrupts production.
Innovation Solution
A tool arrangement that uses a carrier with adjustable components to detect panel thickness and center the tool, allowing for self-adjustment based on the panel's thickness, eliminating the need for reconfiguration and enabling consistent processing across different panel dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a scanning device detects the actual structure of the side surface and adapts it to a desired structure, then the processing quality is improved, but the device complexity and reconfiguration time increase for each new panel
Solution Approach 1:
The patent extracts the complex scanning and target structure recording system from the processing device. Instead of using a scanning device to detect and adapt to desired structures, the invention uses a simple mechanical centering system with feeler rollers that automatically position the milling tool based on the panel's actual dimensions, eliminating the need for complex detection and programming systems while maintaining processing quality
Solution Approach 2:
The milling device is designed to self-adjust to each panel through mechanical centering. The feeler rollers automatically measure the panel thickness and the tool positioning system self-adjusts the tool position based on these measurements, eliminating the need for external scanning devices and programmed target structures. The system serves itself by using the panel's own dimensions to determine the correct tool position
2Manufacturing precision
If a new target structure is recorded and stored for each new panel, then the processing accuracy is improved, but the productivity decreases due to reconfiguration time
Solution Approach 1:
The patent eliminates the need for preliminary recording and storage of target structures by implementing immediate mechanical centering. As each panel enters the processing position, the feeler rollers instantly measure the panel thickness and the tool positioning system immediately adjusts the tool position accordingly, without any delay for data recording, processing, or programming
Solution Approach 2:
The patent replaces the electronic control system (scanning devices, target structure recording, and programmed adaptation) with a purely mechanical centering system. The feeler rollers mechanically measure the panel dimensions and mechanically position the tool through linkages and adjustments, eliminating the need for electronic data processing and programming operations that cause reconfiguration delays
3Manufacturing precision
If milling tools are realigned for each given panel, then the processing precision is improved, but the ease of operation and time consumption worsen
Solution Approach 1:
The milling device performs self-alignment through its mechanical centering system. The feeler rollers automatically measure the panel thickness and the tool positioning mechanism self-adjusts the tool position based on these measurements, eliminating the need for operator intervention in the alignment process. The system aligns itself without requiring skilled operation or manual adjustment
Solution Approach 2:
The patent implements a dynamic tool positioning system that automatically adapts to each panel's dimensions. The feeler rollers and tool positioning linkages create a mechanically dynamic system that continuously adjusts the tool position in response to varying panel thicknesses, providing automatic adaptation without requiring static pre-programming or manual reconfiguration for each panel
