Roller Conveyor Textile Web Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller conveyors used in control stations, such as airport luggage check areas, face issues with small objects falling through and the visibility of underlying mechanisms, which can lead to mechanical installation difficulties, noise, vibrations, and injury risks, especially when driven rollers are involved.
Innovation Solution
A roller conveyor with an elastically flexible textile web attached via a combination of welt and welt rail to the frame, providing noise insulation, vibration damping, and preventing injury by yielding when a person reaches between the rollers, while also allowing for easy installation and hiding the mechanics with a closed or net-like design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If fixed metal or plastic coverings are provided under the roller conveyor, then the mechanics underneath are hidden and small objects cannot fall through, but the cladding surfaces cause vibrations and resonances that amplify mechanical running noise and create injury risks
Solution Approach 1:
The patent applies a flexible textile web instead of rigid metal or plastic coverings. The textile web is suspended beneath the roller conveyor and can flexibly deform when contacted, preventing injury while still covering the mechanics underneath. This flexible material absorbs vibrations rather than amplifying them, resolving the noise amplification issue while maintaining safety.
Solution Approach 2:
The patent changes the physical parameters of the covering material from rigid (metal/plastic) to flexible (textile). This parameter change transforms the material's interaction with vibrations and mechanical forces, allowing it to dampen rather than amplify noise and to yield under contact to prevent injury.
2Area of stationary object
If solid metal or plastic plates are used for covering, then complete coverage is achieved, but the plates are mechanically difficult to install and fasten
Solution Approach 1:
The flexible textile web can be easily suspended and attached to the roller conveyor frame without complex fastening mechanisms. Its flexibility allows it to conform to the underlying structure and be installed with minimal mechanical effort, resolving the installation difficulty while maintaining complete coverage of the mechanics underneath.
3Productivity
If driven transport rollers are used for automatic transport, then productivity is improved, but the injury risk increases when a person reaches between the rollers
Solution Approach 1:
The flexible textile web is positioned beneath the roller conveyor to act as a cushioning layer before injury can occur. If a person reaches between the driven rollers, the textile web yields and absorbs the contact, preventing injury from the driven rollers while allowing the rollers to maintain their automatic transport function.
4Object-affected harmful factors
If a closed or net-like textile web with small mesh size is used, then the mechanics underneath are hidden and advertising purposes are enabled, but the material must maintain elastic flexibility for safety
Solution Approach 1:
The textile web is designed as a closed or net-like structure with small mesh size that maintains elastic flexibility. This allows it to function as a visual barrier hiding the mechanics underneath while its elastic properties enable it to yield under contact for safety. The flexibility is maintained through the textile's inherent material properties and construction.
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 flexible textile web solution addresses the installation and safety issues, reduces noise and vibrations, and prevents injuries by yielding when contact is made, while also enabling easy access and potential use for information or advertising through printing.
Implementation Method 1
The textile web is preferably elastically flexible. As a result, it can also be installed in places that are difficult to access with little effort and provides additional noise insulation and vibration damping.
Implementation Method 2
the large cladding surfaces can cause vibrations and resonances, which amplify the mechanical running noise... provides additional noise insulation and vibration damping
Implementation Method 3
provides additional noise insulation and vibration damping

AI summary
The invention relates to a roller conveyor (1) for transporting items, in particular luggage, comprising a plurality of transport rollers (2) which are arranged at a distance from each other in an axially parallel manner and supported at both ends thereof on lateral longitudinal carriers of a frame that extend in the transport direction. A textile web, which is fastened at both longitudinal sides to the frame, is arranged directly beneath the transport rollers and extends in parallel to the transport surface.
