Feeder Exchange Control for Schedule-Adaptive Mounting Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems lack reliable operation when changes in production schedules or component shortages occur, as the exchange of feeders is not systematically managed, leading to potential operational disruptions.
Innovation Solution
A moving work management device that creates exchange order information based on the current arrangement state and mounting conditions of the holding members, prioritizing collection and replenishment processes to ensure efficient and reliable operation of the moving work device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a moving work device automatically exchanges feeders in a mounting system, then feeder replenishment and collection can be easily performed, but the system cannot adapt when production schedules change or unexpected component shortages occur
Solution Approach 1:
The management control section receives arrangement state information from the mounting device about the current status of feeders and holding members, then uses this feedback to dynamically create or modify exchange order information. This closed-loop feedback mechanism enables the automated moving work device to adapt to schedule changes and component shortages by adjusting its exchange operations based on real-time system state.
Solution Approach 2:
The system transitions from a static, predetermined feeder exchange schedule to a dynamic exchange order that can be modified in real-time. The management control section dynamically creates exchange order information based on current arrangement state and mounting condition information, allowing the moving work device to adapt its operations to changing production requirements and unexpected situations.
2Device complexity
If the moving work device operates without systematic management of exchange operations, then the system structure remains simple, but operational reliability decreases when unexpected situations occur
Solution Approach 1:
A management control section is introduced as an intermediary between the mounting device and the moving work device. This intermediary receives arrangement state information from the mounting device, processes it according to mounting conditions, and generates exchange order information for the moving work device. This intermediary layer coordinates exchange operations systematically, improving reliability without requiring complex modifications to the moving work device itself.
Solution Approach 2:
The management control section creates exchange order information in advance based on mounting condition information and current arrangement states. By preparing exchange orders beforehand and systematically managing the sequence of collection and replenishment operations, the system ensures reliable operation even when unexpected situations arise during production.

AI summary
The mounting system includes a mounting device having a holding member, a moving work device for collecting or loading a holding member, and a moving work management device. The moving work management device comprises a management control section configured to create exchange order information including a collection order for collecting the holding member that the moving work device operates and/or a replenishment order for replenishing the holding member based on arrangement state information including the usage state of the holding member currently loaded to the mounting device and mounting condition information according to which the mounting device performs the mounting process.
