Automated Feeder Cassette Delivery System with Conflict-Aware Exchange Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current delivery systems for components in feeder cassettes to placement devices involve extensive manual work and result in overlapping exchange periods, disrupting the trouble-free operation of placement devices, especially when dealing with a large number of feeder cassettes.
Innovation Solution
A method and system that record mandatory exchange periods, compare them for time conflicts, determine optional exchange periods, and deliver components in feeder cassettes during these periods to avoid delays, using a delivery system with movement devices and communication capabilities to manage feeder cassette exchanges dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If feeder cassettes are exchanged manually in the prior art, then the exchange process is simple to perform, but overlapping exchange periods occur that disrupt placement device operation
Solution Approach 1:
The system records mandatory exchange periods for each feeder cassette in advance and compares these periods to identify time conflicts before they occur. By determining optional exchange periods proactively and delivering feeder cassettes during these periods, the system prevents overlapping exchanges that would disrupt placement device operation, thereby maintaining reliability while automating the exchange process.
2Productivity
If the number of feeder cassettes is increased to meet production demands, then component delivery capacity is improved, but the complexity of managing exchange periods increases
Solution Approach 1:
The delivery system automatically records mandatory exchange periods for each feeder cassette, compares these periods to identify time conflicts, and determines optimal optional exchange periods without human intervention. The system autonomously manages the complexity of coordinating multiple feeder cassette exchanges, allowing production capacity to scale without proportionally increasing management complexity.
3Loss of time
If feeder cassettes are delivered during mandatory exchange periods, then placement device waiting time is reduced, but time conflicts between multiple feeder cassettes occur
Solution Approach 1:
The system records mandatory exchange periods for each feeder cassette and continuously compares these periods to identify time conflicts. Based on this feedback, the system determines optional exchange periods that avoid overlaps while still delivering feeder cassettes in advance of mandatory exchanges. This feedback loop enables the system to adapt exchange timing to prevent conflicts while minimizing placement device waiting time.
