Feeder Placement Control for Faster Production Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mounting systems, the setup changing operation for production switching is not efficiently managed, leading to increased time and inefficiency in feeder replacement during production schedule changes.
Innovation Solution
A management device and method that sets attachment position information for feeders based on production plans, positioning feeders to be replaced closer to storage sections, allowing the moving work device to reduce movement distance and time during production switching, enabling more efficient setup changing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If feeders are attached to attachment portions farther from the storage section, then the mounting device can maintain flexibility in feeder arrangement, but the moving work device requires longer movement distance and more time to exchange feeders during production switching
Solution Approach 1:
The management control section performs preliminary arrangement of feeders by attaching feeders that are likely to be replaced during production switching to attachment portions closer to the storage section. This preliminary positioning reduces the movement distance and time required when feeder exchange is actually needed, directly improving feeder exchange efficiency while minimizing movement time loss
Solution Approach 2:
The system changes the positional parameter of feeders dynamically based on production switching requirements. By adjusting which feeders are attached to which attachment portions according to predicted replacement patterns, the system optimizes the balance between feeder arrangement flexibility and exchange efficiency, reducing time loss during setup changing operations
2Adaptability or versatility
If feeders are frequently moved during production switching, then the setup changing operation can adapt to different production schedules, but the time required for feeder exchange increases
Solution Approach 1:
The management control section performs preliminary analysis of production schedules to predict which feeders will be replaced during setup changing operations. Based on this prediction, it pre-arranges feeders in optimal positions closer to the storage section, enabling quick exchange while maintaining adaptability to different production schedules. This reduces setup changing time without sacrificing production flexibility
Solution Approach 2:
The system applies different arrangement strategies to different feeders based on their replacement probability. Feeders with high replacement probability are positioned closer to the storage section, while others maintain their original positions. This localized optimization maintains overall system adaptability while minimizing time loss for frequent exchanges
