Component Feeder Selection for Simultaneous Pickup After Shortage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices require pre-attachment of multiple feeders and struggle with efficient component mounting when component shortages occur, as they need to determine the next feeder position based on the original feeder's position, leading to inefficiencies and potential component expiration.
Innovation Solution
A determination device that acquires and analyzes the attachment positions and types of multiple component feeders to dynamically determine which feeder can supply a specific component type when shortages occur, allowing simultaneous pickup by the mounting head, and includes mechanisms to change feeder positions to prevent component expiration and maintain production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple component feeders are attached in advance to the feeder holding section, then the mounting head can simultaneously pick up components from multiple feeders, but when component shortage occurs in a specific feeder, the system cannot efficiently determine which alternative feeder to use
Solution Approach 1:
The system performs preliminary registration of multiple component feeders, storing their attachment positions and component types in advance. When component shortage occurs, the determination device quickly identifies suitable alternative feeders from the pre-registered information, avoiding time-consuming search and enabling rapid feeder substitution while maintaining simultaneous pickup capability
Solution Approach 2:
The system dynamically determines which feeder to use based on real-time component availability rather than following a fixed feeder assignment. The determination device evaluates multiple factors including attachment position, component type compatibility, and current component levels to flexibly select the most appropriate alternative feeder, optimizing productivity under varying conditions
2Stability of the object's composition
If the attachment position of the next feeder is determined based on the original feeder's position, then the system can maintain a fixed feeder arrangement, but this limits the ability to utilize feeders attached at different positions when component shortages occur
Solution Approach 1:
The system transitions from a static feeder assignment based on fixed position relationships to a dynamic determination process. The determination device evaluates all registered feeders' attachment positions and component types, selecting alternatives based on current needs rather than predetermined position-based rules, thereby achieving both stability in operation and flexibility in adaptation
Solution Approach 2:
The system changes the selection criteria from fixed positional parameters to flexible parameters including component type compatibility, attachment position availability, and current component levels. This allows the system to adapt feeder selection based on varying operational conditions while maintaining stable simultaneous pickup operations
3Productivity
If component feeders are not pre-attached and positioned optimally, then the system can avoid component expiration by flexible arrangement, but the mounting head cannot efficiently perform simultaneous pickup operations
Solution Approach 1:
The system performs preliminary attachment and registration of multiple component feeders with their specific positions and component types stored in advance. This enables the mounting head to execute efficient simultaneous pickup operations while the determination device monitors component levels and proactively determines alternative feeders before component expiration occurs
Solution Approach 2:
The system continuously monitors component levels in each feeder and provides feedback to the determination device. When component levels approach depletion, the system uses the pre-registered feeder information to identify and switch to alternative feeders, preventing component expiration while maintaining optimal simultaneous pickup efficiency

AI summary
A determination device determines a component feeder to be used from among the multiple component feeders attached to a feeder holding section. When a first specific type of component is supplied from a first specific component feeder, a second specific type of component supplied from a second specific component feeder are simultaneously picked up by a mounting head, and a component shortage occurs in the first specific component feeder, the determination device determines a same type component feeder attached to a position which enables simultaneous pickup with the second specific type of component supplied from the second specific component feeder, as a component feeder for supplying the first specific type of component.
