Coin Separation Device With Acceleration Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin separation devices are not reliable in ensuring that only coins are conveyed into a coin collection device, as they can inadvertently allow other objects to pass through due to insufficient recognition and handling mechanisms.
Innovation Solution
Incorporating an acceleration device on the conveying line that recognizes coins and accelerates them out of their conveying movement, directing them towards a coin collection device with a speed greater than the conveying speed, thereby ensuring only coins are collected while other objects are returned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coins are conveyed along a conveying line using a conventional conveying device, then coins can be transported from the inlet container, but other objects may also be conveyed along the conveying line and inadvertently enter the coin collection device
Solution Approach 1:
The acceleration device is integrated into the existing conveying line, extracting and accelerating only the recognized coins from the continuous conveying flow. This allows the conveying device to maintain its simple continuous operation while the acceleration device selectively extracts coins, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The checking device performs recognition of coins before they reach the collection device, and the acceleration device is positioned to accelerate coins at this preliminary stage. This preliminary action ensures that only recognized coins are accelerated toward the collection device, preventing foreign objects from entering while maintaining system simplicity.
2Reliability
If an acceleration device is added to accelerate recognized coins out of the conveying movement, then only coins are reliably conveyed into the coin collection device, but the device complexity increases
Solution Approach 1:
The acceleration device acts as an intermediary between the conveying line and the coin collection device. It receives recognized coins from the conveying line, accelerates them, and directs them into the collection device. This intermediary function ensures reliable coin separation while keeping the conveying device and collection device relatively simple.
Solution Approach 2:
The acceleration device introduces dynamic acceleration to the otherwise steady conveying process. By applying acceleration only to recognized coins at specific locations, the system achieves reliable coin separation without requiring complex modifications to the entire conveying system.
3Reliability
If the acceleration device accelerates coins in conveying direction with speed greater than conveying speed, then coins are effectively separated from other objects, but energy consumption increases
Solution Approach 1:
The acceleration device applies acceleration that exceeds the conveying speed only to recognized coins, rather than accelerating all objects on the conveying line. This partial action ensures effective separation of coins from foreign objects while minimizing unnecessary energy consumption on non-coin objects.
Solution Approach 2:
The acceleration device operates periodically or selectively based on recognition signals from the checking device, accelerating only when a coin is detected. This periodic action pattern reduces overall energy consumption compared to continuous acceleration, while maintaining effective separation when needed.

AI summary
A coin separation device has a conveying device for conveying coins from an inlet container in a conveying direction along a conveying line and a checking device arranged on the conveying line for recognizing a coin that is conveyed along the conveying line. An acceleration device also is provided. The acceleration device is formed to accelerate a coin conveyed along the conveying line and recognized by the checking device in the conveying direction so that the coin is conveyed from the conveying line into a coin collection device. In this way, the coin separation device reliably conveys only coins, and not other objects from the conveying line into a coin collection device.
