Coin Sorting Disc Stripping and Queuing for Single-File Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disc-type coin sorters face inefficiencies due to stacked or overlapping coins entering the system, leading to increased burden on downstream stripping features and reduced overall system efficiency.
Innovation Solution
The coin processing system incorporates a rotatable disc with a resilient pad and a stationary sorting head featuring stripping and queuing areas with angled ramps and beveled surfaces to separate stacked coins and guide them into a single file configuration, improving coin flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entry area is made deep enough to allow thickest coins to freely enter under the disc, then coin entry is facilitated, but stacked or overlapping pairs of coins can also enter, disrupting single-file flow
Solution Approach 1:
The patent applies preliminary action by implementing a stripping area with stripping surfaces positioned before the coins reach the main sorting area. These stripping surfaces proactively separate stacked coins by allowing the lower coin to pass through while retaining the upper coin, preventing the disruption of single-file flow before it occurs in the entry area.
2Reliability
If downstream stripping features are used to separate stacked coins, then coin separation is achieved, but the burden on these features increases and overall system efficiency decreases
Solution Approach 1:
The patent implements preliminary action by placing the stripping area and stripping surfaces upstream, before the coins reach the downstream stripping features. This preliminary separation reduces the workload on downstream stripping features, allowing them to handle only occasionally stacked coins rather than continuously separating stacks, thereby improving overall system efficiency.
3Speed
If coins are not separated early in the process, then the system can operate at higher speeds, but wear and tear on system components increases
Solution Approach 1:
The patent applies preliminary action by implementing the stripping area at the beginning of the coin path, where stacked coins are separated early in the process. This early separation prevents multiple coins from simultaneously engaging with downstream components, reducing friction, wear, and tear on system components while allowing the system to operate at higher speeds without compromising reliability.

AI summary
A coin processing system comprises a rotatable disc including a resilient pad coupled thereto for imparting motion to the plurality of coins, the resilient pad including an outer peripheral edge, and a stationary sorting head. The stationary sorting head includes a lower surface forming a coin path for directing movement of each of the coins, a stripping area of the coin path including at least one stripping surface operable to retain at least one coin when overlapping another coin such that the other coin is separated from the at least one coin by the motion imparted by the rotatable disc, and a queuing area of the coin path that receives the plurality of coins from the stripping area, the queuing area including a beveled surface curving substantially parallel with the outer peripheral edge of the resilient pad to guide the coins in a single file configuration to a discrimination area.
