Dynamic Replenishment Priority Adjustment for Board Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an abnormality occurs in one or more board work machines, the priority of the replenishment work for those machines decreases, potentially leading to a decrease in overall production efficiency if the replenishment is performed based on pre-set priorities.
Innovation Solution
An article management device with a determination section to identify abnormalities in board work machines and a change section to dynamically adjust the priority of the replenishment work based on the type and severity of the abnormality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the replenishment work priority is set in advance for board work machines, then the management process is simple and standardized, but when an abnormality occurs in a board work machine, the overall production efficiency decreases because the priority cannot be dynamically adjusted
Solution Approach 1:
The patent applies dynamics by transitioning from static pre-set priorities to dynamic priority adjustment. The management device automatically changes the priority of replenishment work based on real-time abnormality information from board work machines. When an abnormality is detected, the system dynamically reassigns priorities to ensure optimal production efficiency without requiring complex manual intervention.
Solution Approach 2:
The patent implements feedback by having board work machines transmit abnormality information back to the management device. This feedback loop enables the management device to automatically detect abnormalities and adjust replenishment priorities accordingly. The feedback mechanism allows the system to respond to changing conditions while maintaining relatively simple management processes.
2Reliability
If the replenishment priority is automatically reduced when an abnormality occurs, then the system responds to abnormalities, but the overall production efficiency may still decrease because other machines without abnormalities are delayed
Solution Approach 1:
The patent applies local quality by adjusting priorities locally for affected machines rather than applying a blanket priority reduction to all machines. When an abnormality occurs in a specific board work machine, only the replenishment priority for that particular machine is reduced, while other machines without abnormalities maintain their original priorities. This localized approach ensures reliable abnormality response while preserving overall production efficiency.

AI summary
An article management device includes a determination section and a change section. The determination section determines whether there is an abnormality in multiple board work machines configured to perform a predetermined board work on a board. The change section changes a degree of priority of a replenishment work of replenishing the multiple board work machines with articles used in the multiple board work machines based on a type of abnormality in an abnormal work machine that is at least one of the multiple board work machines determined to have an abnormality by the determination section.
