Coin Dispensing Rebound Member for High-Speed Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin dispensing apparatuses face challenges in detecting small-diameter coins without lowering dispensation speed and risking damage to the coin detecting device, as small-diameter coins may not produce continuous detection signals due to their short length and fast speed.
Innovation Solution
A coin dispensing apparatus that includes a rebound member where coins strike and rebound, extending the detection length for non-contact coin detecting devices, allowing continuous signal output without reducing dispensation speed, and using an electromagnetic type coin detecting device for reliable detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the coin speed is increased to improve dispensation speed, then productivity is improved, but the detection signal continuity is lost because small-diameter coins pass through the detection zone too quickly
Solution Approach 1:
The patent introduces a rebound member to change the spatial trajectory of the coin. Instead of the coin moving in a straight line through the detection zone, the coin strikes the rebound member and changes direction, effectively extending the detection path length. This dimensional change in motion trajectory allows the detection zone to cover a longer effective distance, ensuring continuous detection signals even at high dispensation speeds for small-diameter coins.
2Measurement precision
If the detection zone length is increased to improve detection reliability for small-diameter coins, then measurement precision is improved, but the physical space required increases
Solution Approach 1:
The patent uses the dynamic rebound of the coin off the rebound member to extend the detection path. Rather than increasing the static detection zone length, the system exploits the dynamic change in coin direction. The detection zone maintains a moderate length, but the coin's rebound motion effectively multiplies the detection path length, achieving extended measurement precision without proportionally increasing the physical detection zone dimensions.
3Ease of repair
If a noncontact type coin detecting device is used to avoid mechanical contact and damage, then ease of repair is improved, but detection reliability for small-diameter coins deteriorates due to insufficient detection signal duration
Solution Approach 1:
The patent maintains the noncontact detection approach to preserve ease of repair and avoid mechanical damage. To compensate for the short detection signal duration from small-diameter coins, the system introduces the rebound member to extend the coin's interaction path with the detection zone. This dimensional change in motion trajectory ensures that the noncontact detecting device receives sufficient continuous detection signals, maintaining both maintenance-free operation and detection reliability.

AI summary
A coin dispensing apparatus is provided which can detect a dispensed coin without lowering a dispensation speed of coins, even dispensed small-diameter coins without lowering a dispensation speed without damaging a coin detecting device. The coin dispensing apparatus has a throwing-out device and a noncontact type detecting device. A rebound member is provided against which the coin thrown out by the throwing-out device strikes, to rebound in a predetermined direction. The noncontact type coin detecting device continuously detects a coin before the coin strikes against the rebound member and after the coin rebounds.
