Panel Sawing Sequence With Restacking for Mixed Cutting Plans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current panel dividing systems require a strictly sequential process for sawing panels, which is inefficient when panels in a stack have different cutting plans, leading to increased time and resource utilization due to the need for individual sawing of each panel according to its specific cutting plan.
Innovation Solution
The method involves stacking and unstacking panels between sawing process sections to optimize the number of panels sawn together in each section, allowing for joint sawing when cutting lines permit, and using a handling device to manage and align panels for efficient processing with a single sawing line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panels are sawn individually according to their specific cutting plans, then each panel can be processed according to its requirements, but the total time required to divide the plates increases
Solution Approach 1:
The patent combines multiple panels with different cutting plans into a single stack and processes them simultaneously through multiple sawing lines. Each sawing line executes a specific cutting plan for panels positioned at corresponding locations in the stack, allowing parallel processing of different cutting patterns without requiring individual sequential processing of each panel.
2Productivity
If panels are sawn in a stack, then processing efficiency increases, but this is only possible if all panels follow the same cutting plan
Solution Approach 1:
The patent segments the stack of panels into different positional groups, where panels at the same position across multiple stacks follow the same cutting plan. This allows the system to maintain stack processing efficiency while accommodating diversity in cutting requirements by assigning identical cutting patterns to panels in corresponding positions within the stack configuration.
3Device complexity
If a strictly sequential sawing process is used, then the process is simple to manage, but resource utilization decreases and time increases
Solution Approach 1:
The patent implements continuous parallel processing by operating multiple sawing lines simultaneously on different panels within the stack. While one sawing line processes a panel, other lines are processing different panels in parallel, ensuring that the system maintains continuous productive action across all resources rather than idle sequential transitions between single-panel operations.
