Magnetic Chain Conveyor for Metallic Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain conveyor systems for metallic magnetic articles face issues such as damage and noise due to direct contact with magnet units, strong attractive forces that hinder article separation, and difficulties in sampling on inclined or slippery conveyor lines.
Innovation Solution
A chain conveyor system featuring a conveyor chain with synthetic resin link modules, magnet-piece-accommodating chambers, and article-separating magnet pieces that move within these chambers to securely attract and retain articles while allowing for controlled separation, using sprockets and auxiliary conveyors to manage the magnetic attraction and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of attractive magnet units are disposed on the outer circumferential side of the chain base to securely attract metallic magnetic articles, then the articles can be retained on inclined or slippery conveyor lines, but the magnet units come in contact directly with the articles causing damage and vibration noise
Solution Approach 1:
A resin layer is introduced as an intermediary between the magnetic units and the metallic magnetic articles. The resin layer maintains the magnetic attraction force while preventing direct contact between the magnet units and articles, thereby eliminating damage and vibration noise while preserving reliable article retention on inclined or slippery conveyor lines
2Reliability
If attractive magnet units continue to exhibit strong attractive force in the terminal discharge area, then articles are securely retained during conveyance, but it becomes difficult to release or separate the articles for transfer to succeeding conveyor lines
Solution Approach 1:
The magnetic units are designed to dynamically change their attractive force based on position. During the conveyance portion, the magnet units exhibit strong attractive force to securely retain articles. In the terminal discharge area, the attractive force is reduced or deactivated, enabling easy release and separation of articles for transfer to succeeding conveyor lines
3Reliability
If attractive magnet units are disposed on the chain to convey articles, then articles can be retained during conveyance, but it becomes difficult to remove articles for sampling in inclined straight conveying areas
Solution Approach 1:
The magnetic attraction force is dynamically controlled to be strong during conveyance for reliable article retention, but can be locally reduced or deactivated in inclined straight conveying areas where sampling is required, enabling easy article removal for sampling while maintaining secure retention during the conveyance process
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
The system effectively prevents damage and noise, ensures secure attraction and retention on inclined or slippery surfaces, and facilitates smooth article transfer by enabling controlled separation and release, enhancing reliability and efficiency in conveying metallic magnetic articles.
Implementation Method 1
conveys articles by attracting and retaining the articles on the conveying surfaces thereof by magnetism
Implementation Method 2
article-separating magnet pieces that attract the article-attracting magnet pieces within the magnet-piece-accommodating chambers from the chain outer circumferential side to the chain inner circumferential side

AI summary
For a chain conveyor system having a main conveyor having links with an inclined or a slippery wet conveying run extending from a feed end to a discharge end capable of securely attracting and retaining metallic magnetic articles on the run by article-attracting magnet pieces in selected links for attracting and retaining the articles on the run. An auxiliary conveyor for enabling separation of the articles from the conveyor at the discharge end of the run by releasing attraction of the articles. The auxiliary conveyor has links which register with the main conveyor links at the discharge end of the main conveyor system. The registering links of the auxiliary conveyor have article-separating elements operable to reduce the magnetic force of the magnet pieces at the discharge end of the run to enable separation of the conveyed articles from the main conveyor.
