Feeder Loading Sequence for Faster SMT Mounting Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mounting systems with shared feeder arrangements, the time required to start the mounting process is prolonged due to the need to exchange and arrange feeders for multiple mounting jobs.
Innovation Solution
A moving work management device that creates loading order information prioritizing the use of feeders in the current production over the next production, allowing earlier initiation of the mounting process by preferentially loading feeders used in the current production first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shared arrangement of feeders is used to reduce labor of exchanging arrangement positions, then ease of operation is improved, but the time to start the mounting process increases
Solution Approach 1:
The management control section creates loading order information in advance that prioritizes feeders for current production over feeders for next production. This preliminary planning allows the supply section to load current production feeders first, enabling the mounting process to start without waiting for all feeder arrangements to be completed, thus reducing the time to start mounting while maintaining the shared arrangement system.
2Device complexity
If feeders are loaded in shared positions for multiple mounting jobs, then device complexity is reduced, but productivity decreases due to longer setup time
Solution Approach 1:
The system performs preliminary creation of loading order information that sequences feeder loading to prioritize current production needs. This advance planning enables the mounting process to start as soon as necessary feeders are loaded, rather than waiting for complete feeder arrangement, thus improving productivity while maintaining the simplified shared arrangement structure.
Solution Approach 2:
The loading order information dynamically prioritizes feeders based on production timing (current vs. next production). This dynamic sequencing allows the system to adapt the loading sequence to production needs, enabling faster startup while maintaining the flexible shared arrangement configuration for multiple mounting jobs.

AI summary
The mounting system includes a mounting device including a mounting section, a supply section, and a mounting control section, and a moving work management device. The moving work management device creates loading order information including the loading order of the feeders to be loaded to the loading section with preference given to the feeders to be used in the current production over the feeders to be used in the next production onward based on multiple pieces of feeder arrangement information and the order of use of the multiple feeders, the multiple pieces of feeder arrangement information handling each of multiple pieces of mounting condition information for producing multiple types of mounting targets including the arrangement positions of the feeders created corresponding to positions shared among the productions of multiple types of mounting targets.
