Multi-Track Irradiation Sensor Segmentation for Product Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial product irradiation testing, existing systems face challenges in ensuring that only one product is irradiated at a time to prevent foreign body misassignment and in efficiently managing product flow, leading to potential time delays and safety risks when products are fed on multiple tracks.
Innovation Solution
Assigning separate sensors to each track to detect when products reach a predetermined target position, allowing for precise control of the irradiation process and safe closure of the bulkhead, while using individual means of propulsion and optional second sensors to monitor product length and position for optimized processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If products are fed on multiple tracks simultaneously to increase productivity, then product throughput is improved, but the risk of product overlap and foreign body misassignment increases
Solution Approach 1:
The system divides the monitoring function into separate segments by assigning individual sensors to each track. This allows independent detection of product positions on multiple tracks without interference, enabling simultaneous multi-track operation while maintaining accurate foreign body detection and preventing misassignment.
2Device complexity
If a single sensor monitors all tracks jointly to reduce device complexity, then device complexity is reduced, but the ability to detect which specific product blocks the opening deteriorates
Solution Approach 1:
Instead of using a single sensor to monitor all tracks, the system segments the monitoring function by providing separate sensors for each track. This maintains relatively simple device architecture while enabling precise identification of which specific product blocks the opening, eliminating information loss about product positions.
3Loss of time
If the bulkhead is closed as soon as one product reaches the housing to minimize processing time, then processing time is reduced, but safety risks increase when products overlap
Solution Approach 1:
The system uses feedback from individual track sensors to continuously monitor product positions and determine when the bulkhead can safely be closed. The control unit receives real-time information about which products have reached the housing and which tracks are clear, enabling timely bulkhead closure that minimizes processing time while ensuring safety by confirming no products are overlapping or blocking the opening.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures accurate product positioning and efficient irradiation by preventing overlap, reducing processing time, and enhancing safety by allowing for individual tracking and control of each product's movement within the irradiation zone.
Implementation Method 1
at least one separate sensor is assigned to each track in order to detect when the product moved on the respective track has reached a predetermined target position along the conveyor route
Implementation Method 2
Irradiation with x-rays is offered for this purpose (throughout this disclosure and the accompanying claims the term 'x-ray' is meant to be representative of other irradiation processes as well)
Data Source
AI summary
A test device for the irradiation of products which are fed into a housing along at least two tracks. At least one separate sensor is provided for each track in order to separately monitor the arrival at a target position selected individually for each track preferably within the housing of the test device.
