Bulk Feeder Cleaning Verification Before Component Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Components supplied by bulk feeders are not packaged and require effective management to ensure that unused components are removed from the conveyance path when changing types, necessitating a system to manage the loading state and cleaning history.
Innovation Solution
A feeder management system that includes a storage section for component and cleaning information, and a determination section to ensure cleaning is executed before updating component information based on the cleaning history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If component types are changed in the bulk feeder, then the feeder can supply new components, but unused components remain on the conveyance path causing mixing risks
Solution Approach 1:
The system performs preliminary cleaning of the conveyance path before updating component information. The determination section checks cleaning execution status prior to allowing component type changes, ensuring that unused components are removed in advance to prevent mixing with new components.
Solution Approach 2:
The system implements feedback by storing cleaning information and continuously checking the cleaning execution status. The determination section uses this feedback to control whether component information can be updated, creating a closed-loop control mechanism that ensures reliability during component type changes.
2Reliability
If cleaning is performed before every component type change, then component mixing is prevented, but system complexity and operation time increase
Solution Approach 1:
Instead of requiring cleaning before every single component type change, the system performs cleaning selectively based on stored cleaning information. The determination section checks whether cleaning has been executed and only prevents updates when cleaning is missing, applying cleaning action only when necessary rather than universally.
Solution Approach 2:
The system uses information copying by storing cleaning execution status in storage section 71. Instead of real-time monitoring, the system copies and checks stored cleaning information to make determination, simplifying the management complexity while maintaining reliability.
3Reliability
If cleaning history is tracked and checked, then component loading safety is improved, but information management complexity increases
Solution Approach 1:
The system performs preliminary recording of cleaning information in storage section 71 when cleaning is executed. This advance recording eliminates the need for complex real-time tracking during component type changes, as the determination section simply checks the pre-stored cleaning status.

AI summary
A feeder management system includes a storage section configured to store component information including a type of a component loaded in a bulk feeder and cleaning information providing an execution history of cleaning including, as its cleaning target, at least a conveyance path along which the component is conveyed in the bulk feeder in association with the bulk feeder, and a determination section configured to determine whether the cleaning is executed before an update request for the component information is made based on the cleaning information when the update request for the component information is received.
