Conveyor Chain Link Integrating Tension Load Cell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor chain systems lack effective solutions for monitoring tension without compromising the functionality of the chain, as existing designs often interfere with the operation or require complex integration of tension load cells.
Innovation Solution
A single link in the conveyor chain is designed to incorporate a tension load cell, with a main body portion and cap portion that securely house the load cell, along with auxiliary cavities for circuitry and batteries, allowing for wireless monitoring and lubrication control, while maintaining the chain's operational integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tension load cell is incorporated into a conveyor chain link, then tension monitoring capability is improved, but the chain's operational functionality deteriorates
Solution Approach 1:
The patent combines the tension load cell with the chain link structure by integrating the load cell housing into the link body. The load cell is positioned within the link and connected to the pin, allowing simultaneous tension measurement and chain function. The cap secures both the load cell and maintains the link's mechanical integrity, resolving the contradiction between adding monitoring capability and preserving operational reliability.
2Measurement precision
If a tension load cell is incorporated into a conveyor chain link, then tension monitoring capability is improved, but device complexity increases
Solution Approach 1:
The link structure is designed to serve multiple functions: the main body provides structural support, the cap secures components and maintains the link's mechanical function, and together they house the load cell. This multi-functional design integrates monitoring capability into the existing link without requiring separate mounting structures, thereby improving tension monitoring while limiting complexity increase.
3Extent of automation
If auxiliary cavities for circuitry and batteries are added to the link, then wireless monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent implements nesting by placing the load cell within the link body, and positioning auxiliary cavities for circuitry and batteries within the same link structure. This nested arrangement consolidates multiple components (load cell, circuitry, batteries) into a single link, enabling wireless monitoring capability while containing complexity within a compact, integrated design rather than distributing components across multiple separate elements.

Function Achieved in This Case
This design enables continuous tension monitoring and lubrication management without disrupting the conveyor's function, enhancing the detection of wear and lubrication issues, and improving the overall efficiency and reliability of the conveyor system.
Implementation Method 1
a tension load cell (50) positioned between the cap portion (520) and the main body portion (320) for measuring tension forces applied along a longitudinal axis (1) of the single link (210)

AI summary
At least one single link of a conveyor chain is configured to support a tension load cell. A main body portion of the link includes a central cavity sized to contain the load cell, which has been inserted therein through an opening of the main body portion, and at least one auxiliary cavity to contain at least one battery cell and circuitry. A cap portion of the link closes off the opening into the cavity to enclose the load cell therein. One or both of the main body and cap portions may include a bore to receive a fastener for attaching to an end of the inserted load cell, and both portions include a bore oriented to receive a pin of a mating dual link of the conveyor chain. The cap portion may also include anti-rotation surfaces to mate with one or both of: the load cell and the opening.
