Feeder Exchange Management in SMT Mounting Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems do not efficiently manage the exchange of feeders when component depletion occurs, leading to increased downtime due to the moving time required by the moving work device during the exchange operation.
Innovation Solution
A moving work management device and method that creates arrangement execution information to position a feeder for exchange in the vicinity of a feeder with an advance notification of component depletion, allowing for immediate replenishment without the need for the moving work device to move the feeder after depletion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the moving work device moves the feeder for exchanging after component depletion occurs, then the exchange operation can be performed, but the time required for the exchange operation increases due to the moving time of the moving work device
Solution Approach 1:
The management control section creates arrangement execution information to pre-position the feeder for exchanging in the vicinity of the loading section before component depletion occurs. This preliminary arrangement ensures that when depletion is detected, the moving work device only needs to perform a short relocation rather than traveling from a distant storage location, thereby reducing the time required for the exchange operation while maintaining automatic exchange capability
2Quantity of substance
If the feeder for exchanging is positioned far from the loading section, then more feeders can be stored, but the moving time of the moving work device increases during exchange operation
Solution Approach 1:
The system pre-positions the feeder for exchanging in the vicinity of the loading section before depletion occurs, creating an intermediate staging area that balances storage capacity requirements with quick access needs. This preliminary arrangement allows the majority of feeders to remain in distant storage while ensuring the specific feeder needed for exchange is already positioned nearby, minimizing moving time without compromising overall storage capacity
Solution Approach 2:
The loading section vicinity serves as an intermediary zone between the distant feeder storage and the active mounting position. By creating this intermediate staging area where feeders are temporarily positioned before final exchange, the system resolves the contradiction between maintaining large storage capacity and enabling rapid exchange operations, as the intermediary position reduces travel distance without requiring permanent expansion of the immediate working area

AI summary
A moving work management device is used in a mounting system including a mounting device having a supply section, configured to load a feeder having a holding member configured to hold a component, to one or more loading sections, and a mounting section configured to mount the component supplied from the supply section to a mounting target; and a moving work device having a moving control section, configured to move the feeder, for collecting the feeder from or replenishing the feeder to the supply section. After acquiring the component depletion notification notifying of a component depletion of a feeder, the moving work management device creates arrangement execution information of moving work device for moving and loading the feeder for exchanging to a loading section in the vicinity of the component depleted notification feeder.
