Feeder Storage Judgment for Mounter Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for determining production conditions for a mounter that produces multiple types of boards are time-consuming and inefficient, particularly when judging whether all necessary part feeders can be stored in the mounter, leading to delays in scheduling and potential production disruptions.
Innovation Solution
A method that determines production conditions by judging whether all necessary part feeders can be stored simultaneously in the mounter, using an interactive system to communicate with operators and provide guidance on modifying conditions, such as eliminating or switching board types, to ensure efficient feeder placement and scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional part placement method is used to decide placement positions of part feeders, then accurate and optimized placement can be achieved, but a lot of time is required for trial-and-error processes and processing
Solution Approach 1:
The system performs preliminary judgment on whether all necessary part feeders can be stored in the part supplying unit before actual part placement. This early assessment prevents time-consuming trial-and-error processes by determining feasibility in advance, allowing operators to modify production conditions proactively if storage capacity is insufficient.
2Adaptability or versatility
If all necessary part feeders are required to be stored simultaneously in the part supplying unit, then complete production capability is maintained, but the judgment process becomes time-consuming and complex
Solution Approach 1:
The system extracts the judgment process from the overall part placement workflow, performing it as a separate preliminary step. This isolation allows the system to quickly assess storage feasibility without being bogged down by the complexity of full placement optimization, reducing time loss while maintaining production flexibility.
Solution Approach 2:
The judgment of whether all necessary part feeders can be stored is performed in advance, before actual placement decisions are made. This preliminary action provides operators with early feedback on production feasibility, enabling timely modifications to production conditions if the part supplying unit cannot accommodate all required feeders.
3Ease of operation
If trial-and-error processes are used to determine feeder placement, then optimal placement configuration is achieved, but production schedule determination is significantly delayed
Solution Approach 1:
The system performs preliminary judgment on feeder storage feasibility before engaging in placement optimization. This early assessment prevents unnecessary trial-and-error processes by identifying in advance whether the part supplying unit has sufficient capacity, thereby maintaining scheduling efficiency while preserving optimization capabilities when feasible.

AI summary
This invention provides a production condition determining method by which a production schedule of boards can be determined in a short time. The production condition determining method is for determining production conditions, under which various types of boards are to be produced. This method includes: judging whether or not all of part feeders necessary to produce the various types of boards can be stored simultaneously in part supplying units in a mounter, by comparing the number of the necessary part feeders, with the number of part feeders which can be stored in the part supplying units; and outputting a guidance for modifying the production conditions so that the various types of boards can be produced, when the judgment is made that all of the necessary part feeders cannot be stored simultaneously in the part supplying units.
