Coin Sorting Plate Recessed Slots High-Speed Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin sorting plates face jamming issues when operated at high speeds due to coins not falling through openings before striking the downstream wall, especially when larger coins are pressed against the wall by smaller ones.
Innovation Solution
The coin sorting plate design includes coin receiving recesses with a uniform upstream section and a downstream section with a proximity sensor, allowing coins to drop short distances and be directed off the plate, reducing jamming risks and enabling reliable individual counting and sorting at higher speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the coin sorting machine operates at high speed, then productivity increases, but coins may not fall through openings before striking the downstream wall causing jamming
Solution Approach 1:
The recesses are positioned upstream of the openings, allowing coins to be separated and fall into recesses before reaching the downstream wall. This preliminary separation action prevents the jamming problem that occurs at high speeds when coins would otherwise strike the wall before falling through openings.
2Manufacturing precision
If coins are pressed against the downstream wall by upstream coins, then sorting separation is achieved, but the machine jams
Solution Approach 1:
The sorting plate is segmented into multiple recesses, each associated with a specific coin denomination. This segmentation allows coins of different sizes to be separated into distinct compartments before reaching the downstream wall, preventing the pressing and jamming problem while maintaining accurate sorting.
3Adaptability or versatility
If the opening size increases in the downstream direction, then larger denomination coins are sorted, but smaller coins may not be properly separated
Solution Approach 1:
The invention adds a radial dimension to the sorting mechanism by creating recesses at different radial positions on the sorting plate. Each recess is sized to accommodate coins of specific denominations, allowing accurate separation by size while the progressive downstream arrangement maintains the ability to sort multiple denominations simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design significantly reduces jamming and allows for efficient sorting and counting of coins, even at high speeds, by ensuring coins can easily exit the plate and be individually sensed and counted, enhancing the machine's operational reliability and compactness.
Implementation Method 1
A single-layer stream of coins are introduced on an upper surface of the sorting plate, and are urged by centrifugal force against a peripheral wall extending along the outside of the plate.

AI summary
A coin sorting plate for receiving and sorting a stream of coins by the diameter and hence the denomination of the coin has a number of coin recesses that extend along the path of the coin stream. Each coin recess is sized to receive a respective coin diameter. The coin recesses are arranged with the recess openings increasing in size in the downstream direction to progressively remove coins in order of increasing diameter. Each coin recess is bounded by a downstream wall that forces a coin in the recess to move off a peripheral edge of the coin sorting plate for collection or other processing.
