Mounting Line Set-Up Progress Display for Multi-Line Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting systems, it is challenging to accurately grasp the progress status of set-up work across multiple mounting lines, as existing systems struggle to coordinate and display the progress of various set-up tasks performed by multiple workers simultaneously, leading to inefficiencies and difficulties in managing production changes.
Innovation Solution
A component mounting system that includes a storage device connected to multiple mounting board manufacturing machines via a network, which acquires and shares information to display the progress status of set-up work through a display device, allowing workers to monitor and manage the progress of set-up tasks across multiple lines without interrupting production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If set-up work progress is monitored manually without a centralized system, then individual workers can track their own tasks, but the overall progress status across multiple mounting lines cannot be accurately grasped
Solution Approach 1:
The patent merges multiple information sources (mounting machines, set-up work devices, and manual worker inputs) into a single centralized management device that consolidates and displays overall progress status. This allows comprehensive monitoring of set-up work across multiple mounting lines without requiring complex individual tracking systems at each workstation.
Solution Approach 2:
The management device serves multiple functions: it acquires progress information automatically from mounting machines, receives manual input from workers, stores set-up work information, and displays comprehensive progress status. This multi-functional approach eliminates the need for separate specialized devices for each monitoring task.
2Ease of operation
If work instructions and progress are displayed on individual machine screens, then workers receive localized guidance, but coordination and overall progress monitoring across multiple lines becomes difficult
Solution Approach 1:
The patent adds a new dimension of monitoring by implementing a centralized management device that provides a bird's-eye view of set-up work progress across all mounting lines. This complements the existing local machine displays, giving workers both detailed local guidance and awareness of overall progress without interfering with individual machine operations.
3Productivity
If multiple workers perform set-up tasks simultaneously without centralized coordination, then productivity is maintained, but accurate tracking of overall progress becomes impossible
Solution Approach 1:
The management device implements feedback mechanisms by continuously acquiring progress information from multiple sources (mounting machines and worker inputs) and displaying real-time status. This feedback loop enables accurate tracking of simultaneous set-up activities across multiple workers and lines, maintaining productivity while ensuring precise progress measurement.
4Productivity
If set-up work is performed without interruption to production, then productivity is maintained, but monitoring and coordinating progress becomes more complex
Solution Approach 1:
The management device operates autonomously by automatically acquiring progress information from mounting machines and storing data without requiring manual intervention for each data collection event. This self-service capability simplifies the coordination of uninterrupted set-up work across multiple lines while maintaining production continuity.

AI summary
A component mounting system includes a component mounting line, a storage device, and a display device. The component mounting line is formed by connecting a plurality of mounting board manufacturing machines. The storage device is connected to the component mounting line via a network to acquire information from each of the plurality of mounting board manufacturing machines. The display device is connected to the storage device via the network and displays a progress status of set-up work executed when changing a type of a mounting board manufactured by the component mounting line based on information stored in the storage device.
