Modular Toothed Belt Pusher Mount for Coin Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin conveyor belts with toothed surfaces require special structures and materials that increase costs and complicate maintenance, especially when dealing with narrow belts that cannot be warped or replaced easily, limiting their adaptability and efficiency.
Innovation Solution
The design incorporates a gate-like mount part with a hook mechanism on the tooth-side and non-tooth-side holders, allowing pushers to be easily mounted and removed from the toothed belt without elasticity, and a trapezoidal pulley tooth receiving groove for secure engagement, enabling easy manufacturing and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a toothed belt with special structures and materials is used for coin conveyance, then the coin pushing function is improved, but the manufacturing cost and maintenance complexity increase
Solution Approach 1:
The conveyor belt is divided into modular tooth parts with standardized dimensions. Each tooth part can be independently manufactured and assembled, allowing for cost-effective production while maintaining the coin pushing function. The segmentation enables replacement of individual components rather than the entire belt.
Solution Approach 2:
The tooth parts are designed with universal engagement features that work with standard pulleys. The engaging plates can engage with coins of different denominations, providing multi-functional capability. This universality reduces the need for specialized components, lowering manufacturing costs while maintaining reliability.
2Area of stationary object
If a narrow toothed belt is used to save space, then the device footprint is reduced, but the belt cannot be warped or replaced easily, increasing maintenance difficulty
Solution Approach 1:
The narrow belt is constructed from segmented tooth parts that can be independently handled. This segmentation allows the belt to be replaced section by section even in confined spaces, overcoming the limitation of narrow belt replacement difficulty while maintaining compact device footprint.
Solution Approach 2:
The tooth parts are designed with flexible mounting mechanisms that allow for dynamic adjustment during maintenance. The engaging plates can be quickly attached and detached, enabling easy replacement of narrow belts without requiring complex warping or specialized tools, thus improving maintenance ease.
3Reliability
If a toothed belt with engaging plates is used to push coins, then the coin conveyance reliability is improved, but the device complexity increases
Solution Approach 1:
The engaging plate is merged with the tooth part structure, forming an integrated component. This merging reduces the number of separate parts, simplifying the overall device while maintaining the coin conveyance reliability. The engaging plate becomes an inherent feature of the tooth rather than a separate attachment.
Solution Approach 2:
The tooth part is designed to serve multiple functions: it provides structural support, enables pulley engagement, and incorporates the coin-engaging plate. This multi-functionality reduces device complexity by eliminating the need for separate components while maintaining reliable coin conveyance.
4Ease of manufacture
If standard toothed belts are used instead of specialized coin conveyor belts, then the ease of manufacture is improved, but the adaptability for light-weight articles like coins deteriorates
Solution Approach 1:
The tooth parts are designed with local quality variations: standard tooth structures for general belt function, and localized engaging plates with specific geometries optimized for coin engagement. This local differentiation allows standard manufacturing processes to be used while adapting the belt for light-weight articles like coins.
Solution Approach 2:
The tooth part design incorporates universal features that work with standard manufacturing processes while including adaptive engaging plates. The engaging plates can be adjusted or configured for different coin denominations, providing versatility for light-weight articles while maintaining ease of manufacture through standardized components.

AI summary
An article conveyer belt assembly used for example, in a coin sorting device for positively pushing an article, such as a coin along a support surface is provided. A toothed belt has teeth for transmission of power by mounting a plurality of pushers on the belt with a connector removably mounted with a connecting body, a first holder and a second holder spaced a distance from each other to hold onto the conveyor belt. One of the first and second holders has a hook member to close a spaced opening at one end. The first and second holders are cantilevered to be mounted on a conveyor belt. At the other end of the connector body a pusher unit has a first shaft part and a second shaft part cantilevered from the connector body, with a hollow roller snap fitted on the first shaft part and the second shaft part.
