Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin sorting and transferring apparatuses face challenges in efficiently separating and delivering coins of different diameters to a rotating transferring body without increasing cost or size, and in reliably transferring coins to a sensor part without jumping or misalignment.
Innovation Solution
A coin separating and transferring apparatus with a rotary disk having pushers that project from its surface, a radial direction guiding body, and a coin support ledge, where coins are individually pushed and guided along the radial direction guiding part to a sensor part, ensuring smooth and reliable transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable body forming the recessed part is moved in the diameter direction of the rotary disk to deliver coins, then the coin dispensing position can be controlled, but the device complexity increases due to the moving mechanism
Solution Approach 1:
Instead of moving the recessed part (holding part) to control coin dispensing position, the invention inverts the approach by keeping the holding part stationary and moving the pusher to achieve the same effect. The pusher is moved in the diameter direction to push coins to different angular positions on the rotary disk, thereby controlling the dispensing position without requiring the holding part to move.
2Productivity
If scraping projections rotate with the tilted disk to scrape coins one by one, then coins can be separated and sent, but the apparatus size increases
Solution Approach 1:
The invention segments the coin separation function into two independent components: the rotary disk that rotates to present coins, and the pusher that pushes coins individually. This segmentation eliminates the need for a large tilted disk structure with rotating scraping projections, achieving coin separation in a more compact apparatus.
3Force
If the pusher projection amount is increased to push coins effectively, then coin pushing force improves, but coins may jump or misalignment occurs
Solution Approach 1:
The pusher is designed with movable capability in the diameter direction, allowing its projection amount to be dynamically adjusted. This enables the pusher to apply appropriate force to push coins effectively while controlling the pushing depth to prevent coin jumping or misalignment, thereby maintaining both pushing force and transfer accuracy.
4Manufacturing precision
If a radial direction guiding body is added to guide coins along the radial direction, then coin guiding accuracy improves, but the device complexity increases
Solution Approach 1:
The radial direction guiding body is merged with the holding part structure, forming an integrated guiding mechanism. The holding part not only holds coins but also provides radial direction guidance through its structural design, eliminating the need for separate complex guiding components and reducing overall device complexity while maintaining guiding accuracy.

AI summary
A coin separating and transferring apparatus includes a storing container (108) for storing coins (C) in a bulk state, the storing container having a bottom part formed by an inclined rotary disk (112), the apparatus having formed therein a pusher (146) projecting from an upper surface (136) of the rotary disk (112) and having a projection amount equal to or smaller than a thickness of a thinnest coin (C) that the apparatus is to handle, the coins (C) in surface contact with a holding surface (138) formed by the pusher (146) so as to be individually pushed by the pusher (146) along a fixed radial direction guiding part (176) extending from a center part of the rotary disk (112) in a radial direction, and a rotary transferring body (224) rotating about an axial center for guiding the coins (C) from the radial direction guiding part (176) to a sensor part (222). A coin support ledge (174) is formed on an upper side of the holding surface (138) and extending in the circumferential-direction with respect to a rotation axis line (144) of the rotary disk (112). The pusher (146) is placed to project in a rib shape with respect to the holding surface (138) and has a length in a circumferential direction substantially longer than a diameter of a coin having a largest diameter (LC) and a holding edge (166) formed at a rear side of the pusher with respect to the rotating direction of the rotary disk (112), the holding edge having a predetermined radius (R3) from the rotation axis line (144) of the rotary disk (112) and having a predetermined length, and the coins (C) supported in a stationary state at a delivery position (DP) between the radial direction guiding part (176) and the holding edge (166) are started to be pushed by the rotary transferring body (224).
