Feeder Buffer Pre-Arrangement for Faster Mounting Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems lack efficiency in feeder exchange operations, as they do not consider the time required for exchanging feeders, leading to suboptimal production planning and increased operational inefficiencies.
Innovation Solution
A moving work management device and method that pre-arranges standby feeders based on production plans, loading them to a buffer loading section in an order corresponding to their future usage positions, allowing for efficient feeder exchange without detailed positional adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If feeders are exchanged manually or by moving work device without pre-arrangement, then the mounting system can operate, but the feeder exchange time is excessive and reduces productivity
Solution Approach 1:
The management control section creates pre-arrangement information that determines the optimal arrangement of standby feeders in the buffer loading section based on the production plan. This preliminary arrangement is performed before the actual mounting operation, so that when feeders need to be exchanged, they are already positioned correctly and can be loaded quickly without detailed positional adjustments, thus reducing feeder exchange time and improving productivity
2Manufacturing precision
If detailed positional adjustments are performed during feeder exchange, then feeder arrangement precision is improved, but the exchange process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary arrangement of feeders in the buffer loading section based on pre-arrangement information created from the production plan. This preliminary positioning ensures that standby feeders are already in the correct arrangement positions before the mounting operation begins, eliminating the need for detailed positional adjustments during the exchange process and thereby reducing both time and complexity
Solution Approach 2:
The buffer loading section serves as an intermediary between the feeder storage and the mounting loading section. Standby feeders are first arranged in the buffer loading section according to the pre-arranged positions, and then exchanged with the mounting loading section. This intermediary step simplifies the overall exchange process by separating the arrangement function from the exchange function

AI summary
The mounting system includes a mounting device, having a mounting loading section from which components can be picked up and a buffer loading section from which components cannot be picked up, and a moving work device for collecting or loading feeders. Further, this mounting system includes a moving work management device configured to create, in the production of a mounting target, pre-arrangement information, based on a production plan including multiple pieces of mounting condition information, which causes the moving work device to load the standby feeder to be used from the next time onward to the buffer loading section in an order corresponding to the arrangement positions of the feeders from the next time onward.
