Anti-bounce Block for Coin Sorting Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin sorting systems face issues with coins bouncing along the rail, leading to poor sorting due to inconsistent engagement with the coin sorter's resilient rim, resulting in increased missorting, especially for coins with irregular shapes or sizes.
Innovation Solution
The introduction of an anti-bounce block, preferably made of metal and rigidly fastened to the inclined rail block with a finite number of fastening elements, which engages coins at a distance from the first opening to absorb and redirect bouncing energy effectively, reducing missorting by ensuring consistent pressure and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coins are transported down an inclined rail to the coin sorter, then the sorting process is automated and efficient, but coins bounce along the rail leading to poor sorting accuracy
Solution Approach 1:
The patent applies beforehand cushioning by placing a shock-absorbing device at the bottom wall of the downstream passageway before coins reach the sorter. This cushioning element absorbs the bouncing energy of coins in advance, ensuring they arrive at the sorter with reduced vertical motion and improved sorting accuracy while maintaining automated processing efficiency
2Manufacturing precision
If a shock-absorbing device is added to reduce coin bouncing, then sorting accuracy improves, but device complexity increases
Solution Approach 1:
The patent employs a flexible shock-absorbing device in the form of a deformable wall or cushioning element at the bottom of the passageway. This flexible structure absorbs coin impact energy through elastic deformation, reducing bouncing and improving sorting accuracy without requiring complex mechanical systems, motors, or active control mechanisms
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 anti-bounce block design significantly reduces bouncing amplitudes, improving sorting accuracy and reducing missorting errors, with the rectangular anti-bounce block showing better results than a wedge-shaped alternative, while being more cost-effective.
Implementation Method 1
a shock-absorbing device is provided at the bottom wall of a downstream passageway
Implementation Method 2
which absorbs or dissipates most of the coin's kinetic energy
