X-Ray Shielding Structure for Stable Article Inspection Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray inspection apparatuses face issues with articles being caught or changing posture due to large surface friction of X-ray leakage prevention members, leading to potential damage and mixing of foreign matter, and instability in article transport.
Innovation Solution
An X-ray inspection apparatus with a flexible X-ray shielding member and a front member having higher impact and abrasion resistance, positioned upstream, reduces direct contact and wear, while maintaining X-ray leakage prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an X-ray leakage prevention member made of flexible material containing tungsten is used, then X-ray leakage is prevented, but the surface frictional resistance increases causing articles to be caught or change posture during transport
Solution Approach 1:
The shielding system is divided into two distinct components: a flexible X-ray shielding member for radiation protection and a separate front member for friction reduction. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The front member acts as an intermediary element positioned between the article and the shielding member. It mediates the contact interaction, providing a low-friction surface that prevents articles from being caught while the shielding member maintains its X-ray blocking function.
2Ease of operation
If a flexible slip sheet is placed to reduce friction and stabilize transport, then article transport is stabilized, but the slip sheet wears down and damages from contact with articles
Solution Approach 1:
The front member is designed as a replaceable, cost-effective component that can withstand wear and tear from article contact. It serves as a sacrificial element that protects the more critical shielding member and maintains inspection accuracy by preventing foreign matter contamination.
Solution Approach 2:
The front member is positioned in advance to intercept and absorb the wear and damage from article contact before these effects can reach the shielding member. This preliminary protective action ensures the shielding member remains intact and free from foreign matter.
3Ease of operation
If the front member is made thin to reduce impact on articles, then article transport stability is maintained, but the front member may deform more easily
Solution Approach 1:
The material properties and geometric parameters of the front member are optimized to achieve the right balance. By adjusting thickness, material composition, and structural design, the front member achieves sufficient strength to resist deformation while maintaining low impact on transported articles.

AI summary
An X-ray inspection apparatus includes: a conveying unit which transports an article; an X-ray irradiation unit which irradiates the article, transported to an inspection area by the conveying unit, with X-rays; an X-ray detection unit which detects the X-rays transmitted through the article; an inspection unit which inspects the article based on a detection result of the X-ray detection unit; a flexible X-ray shielding member that prevents the X-rays from leaking from a conveying path to the inspection area and is suspended from the conveying path; and a front member that is disposed on the upstream side of the X-ray shielding member so as to overlap the X-ray shielding member and has higher impact resistance or abrasion resistance than the X-ray shielding member.
