X-ray Source Dynamics for Product Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing x-ray inspection systems for moving products face challenges in achieving efficient horizontal irradiation of the top edge or predefined height of products of varying heights, leading to image distortion and increased costs due to the need for multiple scanning devices.
Innovation Solution
A linear displacement of the x-radiation source parallel to the direction of the lower marginal beam of the fanlike x-ray beam ensures consistent oblique irradiation of the lower area, allowing for adjustable beam angles to accommodate different product heights without requiring additional scanning devices, thus optimizing detector usage and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed x-radiation source position is used for side irradiation, then the lower area of products can be examined with oblique beam penetration, but the top edge or predefined height area cannot be irradiated horizontally
Solution Approach 1:
The x-radiation source is made movable along a trajectory that enables it to assume different positions: a first position for oblique irradiation of the lower product area and a second position for horizontal irradiation of the top edge area. This dynamic repositioning allows a single device to perform multiple examination functions that would otherwise require separate fixed scanning devices.
2Adaptability or versatility
If multiple scanning devices are used to examine both lower and top edge areas, then complete product coverage is achieved, but system complexity and cost increase
Solution Approach 1:
A single x-radiation source is designed to perform multiple functions by moving to different positions: examining the lower area with oblique beam penetration and examining the top edge area with horizontal beam penetration. This multi-functionality eliminates the need for separate scanning devices for different product regions, reducing system complexity while maintaining complete examination coverage.
3Measurement precision
If the x-ray beam is directed horizontally at the top edge, then precise examination of the top area is achieved, but the lower area requires separate oblique irradiation
Solution Approach 1:
The x-radiation source moves between a first position for oblique irradiation of the lower area and a second position for horizontal irradiation of the top edge area. This dynamic repositioning allows each area to be examined with the optimal beam direction for image quality while using a single versatile scanning device.
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
This approach enables precise examination of both the top edge and lower areas of products, improving image quality and reducing system complexity and expense by maintaining consistent detector usage across varying product heights.
Implementation Method 1
x-rays, which penetrate the piece goods or rather the filled container and in doing so generate image data that enable the detection of foreign objects
Implementation Method 2
different materials or substances absorb the x-rays penetrating the piece goods differently and thus damp the x-rays differently as well

AI summary
Provided is an apparatus for x-ray examination of moving products, including a conveyor device with a conveying means on which a product to be irradiated rests in a movement plane. The product is transported in at least one of the following manners: along a predetermined movement trajectory at a predetermined speed; in accordance with a predetermined time-dependent course of speed or position; is rotated about a rotary axis that is substantially perpendicular to the movement plane, or any combination thereof. A radiation generating device, configured to generate an x-ray beam, is positioned on one side of the conveying means, and has a detector device, positioned on the opposite side of the conveying means. The radiation generating device is configured to generate an x-ray beam widening in fanlike fashion beginning at an x-radiation source of the radiation generating device.
