Coin Singulating Guide Surface and Transfer Rail Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for separating and forcibly conveying disc-shaped objects, such as coins, experience issues with wobbling and unsteady movement, leading to potential falling and jamming, which limits processing speed and causes wear on transfer rails, and are prone to pin breakage due to design limitations.
Innovation Solution
A device with a guide element featuring an inclined guide surface and a removal surface, a carrier disk with receiving holes, and a transfer rail with a rolling surface and push elements, where the gap between the driving disk and guide surface is narrow enough to prevent objects from getting caught, and the transfer section includes a depression to slow down objects, ensuring smooth and reliable conveyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drive pins are used to abruptly accelerate coins on the transfer rail, then processing speed is improved, but coins wobble and move erratically causing them to fall off the rail and block or damage device parts
Solution Approach 1:
A curved guide surface is introduced as an intermediary element between the drive disc and the transfer rail. This guide surface gradually transitions coins from the drive disc to the transfer rail, mediating the acceleration process to prevent abrupt movements that cause wobbling and falling off.
Solution Approach 2:
The curved guide surface performs preliminary guidance and gradual acceleration of coins before they reach the transfer rail. By preparing the coins' movement trajectory in advance on the curved surface, the system prevents erratic movement and falling off during the transfer process.
2Productivity
If drive pins are used to accelerate coins, then coins are conveyed faster, but severe wear occurs in the area of the transfer rail
Solution Approach 1:
The curved guide surface is designed with a specific curvature that dynamically adapts to the coin's movement. This dynamic geometric design allows for smooth, gradual acceleration that reduces impact forces and friction on the transfer rail, thereby extending its service life while maintaining conveying speed.
3Ease of operation
If two circular grooves are formed in the guide surface for drive pins, then drive pins can move, but small coins penetrate these grooves laterally and block the drive disc
Solution Approach 1:
The harmful circular grooves that caused small coins to penetrate laterally are completely removed from the guide surface. Instead, a continuous curved guide surface is used that provides drive pin movement functionality without creating lateral penetration paths for small coins, thus eliminating the blockage problem.
4Use of energy by moving object
If the gap between drive disc and guide surface is wide, then friction is reduced, but objects can get trapped between the drive disc and guide element
Solution Approach 1:
The gap width between the drive disc and guide surface is optimized to a specific parameter range that balances friction reduction with entrapment prevention. By carefully controlling this dimensional parameter, the system achieves low friction operation while maintaining reliable object handling without entrapment.

AI summary
Device and method for singulating and force-feeding disc-shaped objects (1), in particular coins, comprising a singulating device (2) with a guide surface (3) lying in an inclined plane, to which a conveying surface (8) is connected, a conveying disc (10) having receiving holes (16), wherein the conveying surface (8) extends at an increasing distance from the conveying disc (10) in the conveying direction (W), a rail (20) whose upper surface forms a rolling surface (26) for the objects (1), and a conveying device (42) which is provided with push elements (46). As it rotates in a collection container (6), the conveying disc (10) picks up objects (1) in receiving holes (16) and conveys them to the conveying surface (8), where they roll onto the rolling surface (26) in the conveying direction (W).The push elements (46) reach the objects (1) in the system in a transfer section (22) of the rail (20) and push them in the direction of travel (W) in a processing section (24). The transfer section (22) has a depression (48), the rising part of which leads to the rolling surface (26) and slows down the objects (1) rolling on the rolling surface (26).
