Coin Separation via Type-Adaptive Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coin separating devices are inefficient in conveying coins of different types along a similar trajectory, leading to inconsistent delivery to a coin collecting device, as they do not account for varying physical properties such as size and weight.
Innovation Solution
An acceleration device is introduced that adjusts its acceleration mode based on the recognized coin type, using pulsed or sliding acceleration to ensure coins of different types follow a similar trajectory into the coin collecting device, with the acceleration device being controlled by a checking device that identifies coin types through geometric and electrical property detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional conveying device is used to transport coins of different types, then coins can be conveyed along a conveying path, but coins of different types (with varying size and weight) cannot be conveyed along a similar trajectory, leading to inconsistent delivery to the coin collecting device
Solution Approach 1:
The conveying device transitions from a static constant-speed system to a dynamic variable-speed system. The control unit adjusts the conveying speed based on the detected coin type, enabling the system to adapt its motion characteristics to different coin properties (size, weight) and ensure consistent trajectory across all coin types
Solution Approach 2:
The system changes the operational parameter (conveying speed) based on the detected coin type. By detecting coin characteristics and adjusting the conveying speed accordingly, the system optimizes the trajectory for each coin type, resolving the contradiction between handling diverse coins and maintaining consistent delivery
2Productivity
If the conveying speed is increased to improve productivity, then more coins can be processed per unit time, but the trajectory control precision decreases, affecting delivery consistency
Solution Approach 1:
The system dynamically adjusts conveying speed based on coin type detection results. Different coin types receive different speed adjustments, allowing the system to maintain optimal trajectory control precision for each coin type while maximizing overall processing throughput
Solution Approach 2:
The conveying speed parameter is dynamically changed according to the detected coin characteristics. This parameter adaptation allows the system to balance productivity and precision by optimizing speed for each coin type rather than using a fixed high speed for all coins

AI summary
A coin singulation device (1) comprises a conveying device (2) for conveying coins (M) from an input container (40) in a conveying direction (F) along a conveying line (200) and a testing device (26) arranged on the conveying line (200) for detecting a coin type of a coin (M) conveyed along the conveying line (200).Additionally, an acceleration device (29) is provided, which is configured to accelerate a coin (M) conveyed along the conveyor (200) depending on its detection by the inspection device (26) such that the coin (M) is conveyed from the conveyor (200) into a coin collecting device (3). The acceleration device (29) is configured to act on the coin (M) depending on the coin type detected by the inspection device (26), accelerating it by accelerating it to a first type if the coin (M) is of a first type, and to a second type different from the first if the coin (M) is of a second type. In this way, a coin singulation device is provided that reliably conveys coins from the conveyor to a coin collecting device.
