Coin Feeding Device Radial Separation Concave Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin feeding devices struggle to accurately separate coins of different diameters, leading to issues where smaller coins can be hooked or carried together, resulting in inaccurate processing and potential errors in denomination discrimination.
Innovation Solution
A coin feeding device featuring a rotating disk with a pushing-out disk and a moving body that operates to separate and push out coins one by one, utilizing a protruded portion to prevent additional coins from being hooked and an elastic baffle plate to ensure only one coin is processed at a time, along with an R-shaped chamfering portion to prevent coins from riding on the outer edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed pin spacing is used in conventional rotary disks, then coin separation is simple and device complexity is low, but when diameter difference between coins is large, multiple minimum diameter coins may enter between spaced pins making separation unreliable
Solution Approach 1:
The separating disk is divided into multiple independent separating concave portions arranged radially, each capable of holding and separating one coin at a time. This segmentation allows the system to handle coins of varying diameters reliably without requiring complex adjustable mechanisms, as each concave portion independently performs the separation function.
Solution Approach 2:
The moving body acts as an intermediary mechanism that pushes coins from the coin storage bowl into the separating concave portions and then discharges them one by one. This intermediary structure ensures that only one coin is fed at a time to the next process, preventing multiple coins from being processed simultaneously and improving separation reliability.
2Adaptability or versatility
If fan-shaped concave portion is used for coin separation, then coins of predetermined diameter can be separated, but when coins of multiple different types in diameter are mixed, the structure is not suited for efficiently separating them one by one
Solution Approach 1:
The separating disk with multiple radially arranged separating concave portions is designed to handle coins of various denominations and diameters. Each concave portion can accommodate different coin sizes, making the structure universal and adaptable to multiple coin types without requiring separate mechanisms for each denomination, thus maintaining high separation efficiency.
3Productivity
If rotating disk feeds coins from coin storage bowl, then coins are delivered to next process, but extraneous coins can also be carried by the rotations through the bowl causing feeding errors
Solution Approach 1:
The moving body performs preliminary action by pushing coins from the storage bowl into the separating concave portions before the rotating disk carries them to the discharge position. This preliminary positioning ensures that only one coin is properly seated in each concave portion, preventing extraneous coins from being accidentally carried along and fed to the next process, thus maintaining feeding accuracy while preserving productivity.

AI summary
The present invention provides a coin feeding device that can separate coins of multiple denominations that are different in diameter. A rotary disk has a circular base plate and a pushing out disk with a plurality of space radial projecting portions extending above the circular base plate. The spaces between the radial projecting portions form coin separating concave portions for receiving coins. The circular base plate can have cam grooves. A pivoting moving body can be driven by the cam grooves and can be positioned at either a radially inward surface of the separating concave portion or extended forward to discharge a coin. One side of the separating concave portions are curved as a coin pushing portion while the other side has a protruding portion that is cantilevered to extend into the concave portion and to project upward to remove any extraneous coin that may be carried by movement of the rotary disk.
