Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin separating and detecting devices face challenges in maintaining a low height while ensuring accurate detection, as they often require frequent maintenance and have dimensions that increase in the transport direction, leading to issues with vibration and sensor accuracy, especially when using belts that need tension adjustment.
Innovation Solution
The coin separating and detecting device is designed with a separating and feeding rotating body and a detecting rotating body inclined and aligned laterally, featuring a separating concave portion and a detecting portion introduction guide with an arc-shaped design to minimize vibrations, allowing coins to fall onto a reception area that suppresses spring-up and ensures accurate detection by a sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If coins are transported by a rotating body diagonally upwards along a linear guide, then physical properties can be detected by a sensor, but the device height increases in the vertical direction
Solution Approach 1:
The patent transitions from a vertical/diagonal coin transport path to a horizontal transport path. The coin separating and feeding device moves coins horizontally along a guide rail, and the denomination identification device is positioned horizontally adjacent rather than vertically above, thereby reducing device height while maintaining detection capability
Solution Approach 2:
The patent combines the coin separating and feeding function with the denomination identification function in a horizontally integrated arrangement. The separating and feeding rotating body and the identification rotating body share a common horizontal transport path, merging multiple functions into a compact horizontal configuration
2Ease of operation
If a belt is used for linear movement of coins, then transport can be achieved, but tension adjustment and frequent inspection maintenance are required
Solution Approach 1:
The patent replaces the belt-driven mechanical transport system with a rotating body mechanism. The separating and feeding rotating body and identification rotating body use rotational motion to advance coins along guide rails, eliminating the need for belts, tensioners, and associated maintenance
Solution Approach 2:
The rotating bodies automatically advance coins through their rotational motion without requiring external tension adjustment mechanisms. The system self-regulates coin transport through the mechanical interaction between the rotating bodies and the guide rails
3Length of stationary object
If coins are moved in a horizontal state through a long distance, then the device height can be reduced, but the device dimension in the transport direction becomes larger
Solution Approach 1:
The patent uses dynamic rotating bodies instead of static linear guides. The separating and feeding rotating body and identification rotating body create a compact circular/oval transport path that reduces the linear transport distance while maintaining horizontal coin movement, thereby reducing both device height and transport direction dimension
4Length of stationary object
If the separating and feeding rotating body and detecting rotating body are aligned laterally in parallel, then device height is reduced, but coin vibration may affect detection accuracy
Solution Approach 1:
The patent introduces a coin reception area with vibration suppression functionality before coins enter the detection zone. The reception area cushions coins upon arrival from the separating rotating body, minimizing vibrations before detection occurs, thereby maintaining detection accuracy in the compact horizontal configuration
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
This configuration reduces the device's height, minimizes vibrations, and enables accurate detection of coins by a sensor, allowing for more reliable and long-interval maintenance, while maintaining a compact design.
Implementation Method 1
the detecting portion introduction guide is formed with an arc shape in order to minimize vibrations
Implementation Method 2
the coins that have been separated are fed to a coin detecting device from a coin separating and feeding device configured to push out the coins that have been separated from the separating concave portion by a moving body which is movable in the radial direction of the separating and feeding rotating body, and the coin detecting device includes a detecting rotating body that moves the coins that have been fed along a detecting portion introduction guide

AI summary
[Problem] The object of the present invention is to provide a coin separating and detecting device having decreased height and enabling accurate detection by a sensor. [solution] A coin separating and feeding device 122 and a coin detecting device 124 are disposed in parallel in the horizontal direction. The coins C fed from the coin separating and feeding device 122 fall downwards into the coin handling concave portion 184 of the detecting rotating body 174 of the coin detecting device 124 and are held in the coin reception 184r. Since the reception peripheral edge side portion 184rp of the coin reception 184r is oriented to the rotational center side, the coins are delivered to the arc portion 142a which is centered to the rotational center if the peripheral edge side end 184re is inclined about 45°. The coins C roll on the arc portion 142a roll and reach a static state at the temporary retaining portion 142L formed in the lowest position. Having reached a static state, the coins C are pushed forward by the coin pushing portion 184p of the detecting rotating body 174. Even if the coins C vibrate, the vibrations are resolved in the step in which the coins C roll on the arc portion 142a while being suppressed by the reception peripheral edge side portion 184rp or by that the coins C reach a static state at the temporary retaining portion 142L, so that physical information can accurately be acquired at the sensor portion.
