Linear Panel Machining Layout Without Workpiece Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for processing panel-shaped workpieces, such as kitchen worktops, are complex and require time-consuming alignment and rotation for multiple parts, especially when assembling L-shaped or U-shaped worktops from rectangular pieces, necessitating multiple bore or cut-out placements on narrow sides or undersides.
Innovation Solution
A device with a sequential arrangement of alignment and processing stations, including adjustable alignment aids, independent processing units, and a transport system with grippers or suction clamps, allowing for linear processing without the need for rotation or returning of workpieces, enabling efficient machining of both sides and complex patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If workpieces are circulated or rotated in a complex manner to process multiple sides, then all necessary processing steps can be performed, but the device complexity increases and processing time is extended
Solution Approach 1:
The patent transitions from a vertical/rotational processing arrangement to a horizontal linear arrangement. Multiple processing stations are positioned sequentially along the transport direction, allowing the workpiece to be processed on different sides without rotation. The workpiece is transported horizontally through each station, with processing units positioned to access different faces of the workpiece along the linear path.
Solution Approach 2:
The processing system is divided into multiple independent processing stations, each responsible for specific operations on different sides or features of the workpiece. This segmentation allows each station to be optimized for its specific function while the overall system processes the workpiece linearly through each station in sequence.
2Adaptability or versatility
If workpieces are circulated or rotated to access multiple sides for machining, then comprehensive processing is achieved, but the processing time increases
Solution Approach 1:
The workpiece undergoes continuous linear transport through the processing system without interruption for rotation or repositioning. The transport device moves the workpiece continuously through each processing station in sequence, maintaining constant forward motion and eliminating idle time associated with rotational repositioning.
3Adaptability or versatility
If alignment aids are made adjustable to accommodate different workpieces, then versatility is improved, but the device complexity increases
Solution Approach 1:
The alignment aids incorporate adjustable elements that can be dynamically repositioned to accommodate different workpiece dimensions and processing requirements. The adjustability is implemented through simple mechanical means that allow quick reconfiguration without complex control systems.
