Machine Linkage Control for Dynamic Production Line Recombination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In production sites, the dynamic recombination of production lines requires setting and switching between different user programs for control devices, leading to increased memory usage and complexity, particularly when production lines are reconfigured due to changes in production type or quantity.
Innovation Solution
A control system that includes a first control device and one or more moving systems, each with a second control device, storage, and a mechanism to search for and move a second machine to a position linked with the first machine, and provide a linking user program to enable efficient reconfiguration without manual intervention.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple user programs are set in the control device to support dynamic recombination of production lines, then the adaptability of the control system is improved, but the device complexity and memory usage are increased
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple user programs corresponding to different production line configurations in the control device. When dynamic recombination is needed, the system automatically selects and loads the appropriate pre-prepared program, eliminating the need for manual reconfiguration and reducing the complexity of real-time program management while maintaining high adaptability
Solution Approach 2:
The control device is designed with multi-functionality to execute different user programs for various production line configurations. A single control device can manage multiple production line types by loading appropriate programs, reducing the need for multiple dedicated control devices and thereby lowering overall system complexity while maintaining versatility
2Adaptability or versatility
If multiple user programs are set in the control device to support dynamic recombination of production lines, then the adaptability of the control system is improved, but the loss of time for program setting and switching is increased
Solution Approach 1:
The system performs preliminary preparation by pre-configuring and storing multiple user programs in the control device before actual production line recombination is needed. This allows for rapid program switching without time-consuming manual setup, thus maintaining adaptability while minimizing time loss during reconfiguration
Solution Approach 2:
The control device automatically manages program selection and loading based on production requirements, eliminating the need for manual program setting and switching operations. This self-service capability reduces the time required for reconfiguration while maintaining system adaptability

AI summary
A control system includes: a search part that, among one or more moving systems, searches for the moving system that meets preset requirements; an instruction part that outputs to a moving mechanism included in the moving system being searched an instruction for moving a second machine to be controlled included in the moving system being searched by the search part to a position operable in linkage with a first machine to be controlled; and a provision part that provides to a storage part of a second control device included in the searched moving system a linking user program for controlling the second machine to be controlled to operate in linkage with the first machine to be controlled. This makes it possible to efficiently perform dynamic recombination of the machines to be controlled.
