Backup Member Picker Assignment Across Multi-Head Board Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In board work machines with multiple work heads, the distribution of backup member disposition work execution times and required time can be biased, leading to decreased production efficiency when only one work head is tasked with the disposition work.
Innovation Solution
A disposition assistance device and method that enable efficient execution of backup member disposition work by acquiring and setting the work head based on the accommodation position of a picker in multiple tool stations, utilizing an acquisition section to determine the picker's location and a setting section to assign the appropriate work head for the task.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only one work head is assigned to execute the disposition work of the backup member, then the disposition work can be completed, but the production efficiency decreases due to idle standby time of other work heads
Solution Approach 1:
The picker is designed to be universally applicable across multiple work heads, allowing any work head to execute disposition work. The system assigns the picker to the work head that requires it based on real-time needs, enabling multiple work heads to perform both their primary board work functions and backup member disposition functions as needed.
2Adaptability or versatility
If multiple work heads are used for different types of board work, then board work versatility is improved, but the distribution of disposition work execution becomes biased and inefficient
Solution Approach 1:
The system dynamically assigns the picker to different work heads based on real-time requirements. The assignment is not fixed but changes according to which work head needs to perform disposition work, allowing the system to adapt to varying board work types and disposition needs while maintaining optimal productivity across all work heads.
3Device complexity
If the picker accommodation position is not tracked, then the system is simpler, but the work head assignment for disposition work cannot be optimized
Solution Approach 1:
The system implements feedback by tracking the accommodation position of the picker in tool stations and using this information to optimize work head assignments. The control unit continuously monitors picker locations and adjusts assignments accordingly, creating a closed-loop system that improves disposition work efficiency while maintaining manageable complexity through automated tracking.
