X-Ray Shielding Structure for Stable Article Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray inspection apparatuses face issues with articles being caught or changing posture due to high surface friction of X-ray leakage prevention members, leading to potential damage and foreign matter mixing, and instability in article transport.
Innovation Solution
Incorporating a flexible X-ray shielding member with higher impact and abrasion resistance, suspended from the conveying path, and a front member with lower friction, positioned upstream to reduce direct contact and wear, along with regulatory members to maintain optimal positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible X-ray shielding member is used to prevent X-ray leakage, then X-ray leakage prevention is improved, but the member is easily worn down and damaged by contact with articles
Solution Approach 1:
The invention uses a composite structure consisting of a flexible X-ray shielding member (with high X-ray absorption capability) and a front member made of metal material (with high impact and abrasion resistance). This composite arrangement allows each component to perform its specialized function: the shielding member prevents X-ray leakage while the metal front member protects it from mechanical damage and wear.
2Reliability
If the surface friction of the X-ray shielding member is high to prevent leakage, then X-ray shielding effectiveness is improved, but articles are caught and stop or change posture during transport
Solution Approach 1:
The invention applies different surface properties to different parts of the shielding structure. The front member has a low friction coefficient surface that allows articles to pass smoothly, while the X-ray shielding member behind it maintains high X-ray absorption capability. This local differentiation of surface properties resolves the contradiction between shielding effectiveness and transport stability.
3Reliability
If the X-ray shielding member is placed directly in the conveying path to prevent leakage, then X-ray leakage prevention is improved, but the member is in direct contact with articles causing wear and potential foreign matter contamination
Solution Approach 1:
The invention introduces a front member as an intermediary element between the articles and the X-ray shielding member. This front member, made of metal material with high impact and abrasion resistance, serves as a protective barrier that absorbs mechanical contact from articles, thereby preventing direct contact between the articles and the flexible X-ray shielding member and reducing the risk of foreign matter contamination.

AI summary
An X-ray inspection apparatus 1 includes: a conveying unit 5 which transports an article G; an X-ray irradiation unit 6 which irradiates the article G, transported to an inspection area 4 by the conveying unit 5, with X-rays; an X-ray detection unit 7 which detects the X-rays transmitted through the article G; an inspection unit 10 which inspects the article G based on a detection result of the X-ray detection unit 7; a flexible X-ray shielding member 60 that prevents the X-rays from leaking from a conveying path 4c to the inspection area and is suspended from the conveying path 4c; and a front member 50 that is disposed on the upstream side of the X-ray shielding member 60 so as to overlap the X-ray shielding member 60 and has higher impact resistance or abrasion resistance than the X-ray shielding member 60.
