Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin processing devices require costly stopper mechanisms, occupy significant space, and generate noise and dust due to high-speed collisions with coins.
Innovation Solution
A coin processing device that uses a feed belt and conveyance motor controlled by a detection unit to switch rotation speed for precise coin stopping, eliminating the need for physical stoppers and reducing noise and dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopper mechanism with solenoid and protrusion portion is used to stop coins, then the coin can be stopped reliably, but the manufacturing cost increases and the device occupies more space
Solution Approach 1:
The invention extracts and removes the stopper mechanism (solenoid and protrusion portion) from the coin processing device. Instead of using a mechanical stopper to halt coins, the system relies on the existing feed belt conveyance system controlled by a control unit to stop coins at appropriate positions, thereby eliminating the complex stopper mechanism while maintaining reliable coin handling
Solution Approach 2:
The invention replaces the mechanical stopper system (solenoid-driven protrusion portion) with a control-based system. The control unit manages the feed belt's rotation to achieve coin stopping through controlled conveyance and release, substituting mechanical intervention with intelligent control of the existing conveyance mechanism
2Reliability
If a stopper mechanism is installed to stop coins, then the coin stopping function is achieved, but the occupied space increases and layout freedom is reduced
Solution Approach 1:
The invention removes the stopper mechanism entirely from the device structure. By extracting this space-consuming component and replacing it with control-based coin stopping through the feed belt system, the device occupies less space and gains greater layout flexibility while maintaining the coin stopping function
3Reliability
If the protrusion portion contacts the high-speed conveyed coin to stop it, then the coin is stopped effectively, but collision sound is generated and dust is produced
Solution Approach 1:
The invention replaces the mechanical collision-based stopping method with a control-based approach. The control unit manages the feed belt to decelerate and stop coins smoothly without sudden mechanical impact, thereby eliminating collision sounds and dust generation while maintaining effective coin stopping
Solution Approach 2:
The system prepares for coin stopping in advance by controlling the feed belt's rotation speed and position. The control unit decelerates the feed belt gradually before stopping the coin, cushioning the stopping process to avoid sudden impacts that generate noise and dust

AI summary
A coin processing device includes: a feed belt that normally rotates in contact with the upper side of a coin to convey the coin to a conveyance passage extending from an inlet-side passage portion to an outlet-side passage portion; a conveyance motor that normally rotates the feed belt during the normal rotation; a detection unit that detects the coin passing through a position determined in advance in the conveyance passage; and a control unit that switches the conveyance motor from a first rotation state where the conveyance motor normally rotates at a first rotation speed to a second rotation state where the conveyance motor normally rotates at a second rotation speed slower than the first rotation speed, in response to detection of the coin by the detection unit, and then rotates the conveyance motor.
