Coin processing apparatuses face challenges in accurately and efficiently determining different types of coins, especially when foreign matters are present, leading to jamming and increased processing time, which complicates high-speed coin drawing.
Innovation Solution
A coin processing apparatus is designed with a storage system, a coin drawing section, a slit, a coin bias mechanism, an outer diameter sensor, a material sensor, and a hole sensor to accurately determine and sort coins by diameter and material, allowing for high-speed coin drawing with a simple configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a received-coins determining unit is used to determine coin types during drawing from coin storages, then determination accuracy is improved, but conveying time becomes longer and processing speed decreases
Solution Approach 1:
The patent extracts only the essential determination functions (outer diameter, material, hole presence) needed for accurate coin identification during drawing operations, removing unnecessary complex verification processes. This allows high-speed determination without compromising accuracy by focusing only on the minimum required checks.
Solution Approach 2:
The patent uses sensor-based detection (outer diameter sensor, material sensor, hole sensor) to create a virtual model of coin characteristics during drawing, replacing the need for physical handling and complex mechanical verification. This enables rapid non-contact determination that maintains accuracy while dramatically reducing processing time.
2Measurement precision
If a received-coins determining unit is used to determine coin types during drawing from coin storages, then determination accuracy is improved, but device complexity and costs increase
Solution Approach 1:
The patent designs the coin determination system during drawing operations to use the same sensor types (outer diameter sensor, material sensor, hole sensor) already employed in received-coin verification. This multi-functional approach allows a single set of sensors to serve both coin intake verification and coin drawing determination, eliminating the need for separate dedicated determination units and reducing overall system complexity.
Solution Approach 2:
The patent merges the coin determination functionality into the existing coin drawing mechanism by integrating sensors directly into the conveyance path. Rather than adding separate determination units, the system combines verification and drawing operations into a unified process flow, reducing device complexity while maintaining determination accuracy.
3Productivity
If coins are sorted only by material, then processing speed is maintained, but determination accuracy decreases when foreign matters are present
Solution Approach 1:
The patent applies multiple determination criteria (outer diameter, material, hole presence) at different stages of the coin drawing process. By checking outer diameter first through the slit mechanism, then verifying material and hole characteristics with sensors, the system creates a layered verification approach that maintains high speed while achieving accurate coin identification even in the presence of foreign matters.
Solution Approach 2:
The patent performs preliminary outer diameter filtering through the slit mechanism before coins reach the sensors. This preliminary action eliminates obviously incorrect coins (those with wrong diameters) before more detailed sensor verification is needed, maintaining processing speed by quickly eliminating mismatches while preserving accuracy through subsequent material and hole verification.
