Conveyor Belt Link Alignment Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The alignment of rod receiving apertures in modular conveyor belts is a time-consuming and labor-intensive process due to the flexibility of belt components, particularly when using plastic links or long connecting rods, which complicates the assembly of conveyor belts and increases costs.
Innovation Solution
The implementation of alignment features such as protrusions and frangible tabs on the conveyor belt links, which facilitate the alignment of rod receiving apertures by allowing protrusions to abut and align mating surfaces, thereby simplifying the insertion of connecting rods and reducing assembly time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modular links are made flexible using plastic material, then ease of manufacture and cost-effectiveness are improved, but alignment difficulty increases making assembly time-consuming
Solution Approach 1:
Alignment features (protrusions and recesses) are pre-formed on the modular links during manufacturing. These features automatically guide and align adjacent links when assembled, eliminating the need for manual alignment operations and reducing assembly time while maintaining the flexibility benefits of plastic materials.
2Adaptability or versatility
If connecting rods are made longer to accommodate wider belts, then belt width capability is improved, but flexibility increases making alignment more difficult
Solution Approach 1:
Alignment features act as intermediary elements between the modular links and connecting rods. The protrusions and recesses provide precise alignment guidance during assembly, making the operation of inserting long connecting rods into wider belts straightforward and efficient, thereby improving ease of operation while maintaining belt width versatility.
3Manufacturing precision
If manual alignment of rod receiving apertures is performed, then assembly precision can be achieved, but labor intensity and costs increase
Solution Approach 1:
The modular links are designed with self-aligning features (protrusions and recesses) that automatically guide the alignment of rod receiving apertures during assembly. This self-service mechanism achieves precise alignment without requiring complex manual operations or specialized assembly tools, thereby maintaining manufacturing precision while simplifying the assembly process and reducing labor intensity.

AI summary
A conveyor belt includes a first link having a first protrusion with a first mating surface that is curved. The first protrusion is disposed proximate a first rod receiving aperture of the first link. The belt also includes a second link having a second protrusion with a second mating surface that is curved. The second protrusion is disposed proximate a second rod receiving aperture of the second link. The first mating surface receives and abuts the second mating surface. The second link is restrained against movement in less than three orthogonal directions relative to the first link due to abutment of the first and second mating surfaces. The first and second rod receiving apertures are aligned when the first and second mating surfaces abut. Additionally, the belt includes a connecting rod extending through the first and second rod receiving apertures.
