Coin Deposit Machine Vertical Stacking and Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin depositing and dispensing machines face challenges such as large size due to horizontal arrangement of storing and feeding units, potential jamming and miscounting with coins of different diameters, complex structure and high cost due to the need for additional components like delivery disks, and inefficient collection of recyclable coins.
Innovation Solution
A coin depositing and dispensing machine with vertically arranged storing and feeding units, a rotating disk with a coin elimination unit to prevent simultaneous feeding of multiple coins, and a control system to omit the collection box and manage coin collection and dispensing efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If storing and feeding units are arranged horizontally along the coin transport path, then coin storage capacity is maintained, but the machine's depth size becomes large
Solution Approach 1:
The patent transitions from horizontal arrangement of storing and feeding units to vertical arrangement, utilizing the vertical dimension to reduce machine depth while maintaining coin storage capacity. The rotating disk is positioned vertically, and multiple storing and feeding units are stacked vertically rather than arranged horizontally along the transport path.
2Productivity
If multiple coins of different diameters are fed simultaneously by the guide member, then feeding speed increases, but jamming and miscounting occur
Solution Approach 1:
The patent introduces a coin elimination unit that segments the coin feeding process by eliminating excess coins. The elimination unit includes elimination projecting members that selectively remove coins based on diameter, ensuring only one coin of correct diameter is fed to the guide member at a time, preventing jamming and miscounting while maintaining feeding speed.
Solution Approach 2:
The patent changes the parameter of coin diameter selection by using elimination projecting members with specific dimensions. These members are configured to interact with coins of different diameters, allowing the system to selectively pass coins of the correct diameter while eliminating others, thereby ensuring feeding accuracy without sacrificing speed.
3Reliability
If a delivery disk is added to feed coins from the rotating disk, then coin feeding reliability improves, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates the delivery disk component from the coin feeding mechanism. Instead of using a separate delivery disk to transfer coins from the rotating disk, the invention uses a guide member that directly guides coins from the rotating disk, simplifying the apparatus structure while maintaining feeding reliability through the coin elimination unit.
4Ease of operation
If a collection box is used to store non-recyclable coins, then coin collection is simplified, but device complexity and cost increase
Solution Approach 1:
The patent merges the collection function into the existing overflow box structure. Non-recyclable coins are directed to the overflow box, which serves dual purposes: storing overflow recyclable coins and collecting non-recyclable coins. This eliminates the need for a separate collection box, reducing device complexity while maintaining ease of operation through unified coin collection.
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 solution reduces the machine's depth size without compromising storage capacity, prevents jamming and miscounting, simplifies the structure and reduces costs, and ensures effective collection of recyclable coins.
Implementation Method 1
a coin in a lower area of the rotating disk is caught by any of the projecting members, and the coin is transported from the lower area of the rotating disk to an upper area thereof by the rotation of the rotating disk
Implementation Method 2
the coin stored in the storing and feeding unit is fed out from the storing and feeding unit so as to be dispensed to an outside of the machine body

AI summary
In a coin depositing and dispensing machine 10, a plurality of storing and feeding apparatuses 50 disposed below a deposited-coin transport unit 20 are arranged vertically on plural levels. A transport direction in which a coin is transported by the deposited-coin transport unit and a feeding direction in which a coin is fed out from each storing and feeding unit are substantially perpendicular to each other.
