Linear Conveyor Transfer Control to Prevent Slider Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In linear conveyor systems, interference occurs between linear modules and sliders due to improper positional relationships, leading to potential damage and inefficiencies in transferring sliders between fixed and movable linear modules.
Innovation Solution
A controller-driven system that uses position-related information to determine whether to permit or prohibit the drive of sliders and movable linear modules, preventing interference by managing their positions and movements within defined facing ranges and prohibition regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If movable linear modules are used to transfer sliders between fixed linear modules, then the flexibility and transfer capability of the conveyor system is improved, but the risk of interference between linear modules and sliders increases
Solution Approach 1:
The control device determines whether to permit or prohibit drive based on position related information obtained before the drive is started. This preliminary assessment of positions prevents interference by anticipating potential conflicts before they occur, allowing the movable linear module to operate flexibly while maintaining safety.
Solution Approach 2:
The system continuously monitors position related information of sliders and movable linear modules, using this feedback to dynamically control drive permission. This real-time feedback mechanism enables the system to adapt to changing positions and prevent interference while maintaining transfer flexibility.
2Reliability
If position monitoring and drive permission control are implemented, then interference between linear modules and sliders is suppressed, but the system complexity increases
Solution Approach 1:
The control device automatically determines drive permission based on position related information without requiring external intervention. The system self-regulates by comparing positions and autonomously permitting or prohibiting drive, which maintains high reliability while minimizing the need for complex external control mechanisms.
Solution Approach 2:
The control device acts as an intermediary between the movable linear module and the fixed linear modules, mediating drive permission based on position information. This intermediary function simplifies the overall control architecture by centralizing the decision-making logic in a single control device rather than requiring complex coordination between multiple independent control systems.

AI summary
Whether to permit or prohibit drive of at least one object, out of a slider and a movable linear module, is determined based on position related information on position of the slider or the movable linear module before the drive of the object is started. In this way, in a linear conveyor system for transferring the slider between a plurality of fixed linear modules using the movable linear modules, the occurrence of interference between the linear modules and the slider can be suppressed.
