Feeder Serving Management in Component Mounting Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting systems, feeder management is inefficient due to unnecessary detachment and reattachment when spare feeders are introduced to avoid production suspension, leading to time-consuming serving operations.
Innovation Solution
A management device prioritizes empty slots in the buffer target attachment section for pre-serving feeders, ensuring empty slots in the supply target attachment section, thereby avoiding wasteful detachment and enhancing serving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spare feeder is attached to an empty mounting target attachment section to avoid production suspension, then production reliability is improved, but serving time increases due to necessary detachment and reattachment operations
Solution Approach 1:
The mounting target attachment section is divided into multiple slots, and the buffer target attachment section is divided into multiple slots. By segmenting the attachment sections, the system can store spare feeders in buffer slots separately from active mounting slots, allowing quick swapping without detaching other feeders and reducing serving time while maintaining production reliability.
Solution Approach 2:
The management control section pre-arranges spare feeders in the buffer target attachment section before they are needed. When component shortage is predicted, the spare feeder is already positioned in the buffer, ready for quick transfer to the mounting target attachment section, eliminating the need for time-consuming detachment and reattachment operations during production.
2Productivity
If multiple feeders are attached to the mounting target attachment section for subsequent production, then production continuity is improved, but slot availability decreases, requiring wasteful detachment operations
Solution Approach 1:
The buffer target attachment section serves as an intermediary storage area between the feeder storage and the mounting target attachment section. It holds spare feeders that may be needed for future production, acting as a buffer zone that prevents conflicts between maintaining production continuity and ensuring slot availability for future serving operations.
Solution Approach 2:
The system adds a temporal dimension to feeder management by using the buffer target attachment section for future-oriented storage and the mounting target attachment section for current production. This dimensional separation allows the system to optimize for both production continuity and operational efficiency simultaneously.

AI summary
A management device is for use in a component mounting system including a component mounting machine having a supply target attachment section and a buffer target attachment section. In a case where a target feeder to be used in a target job to be executed from the next time are pre-served on the component mounting machine, the management device is configured to determine a serving destination among empty slots in a supply target attachment section and empty slots in a buffer target attachment section by giving priority to the empty slots in the buffer target attachment section, and cause a work device to pre-serves the target feeder in the determined serving destination.
