Coin Wrapping Machine Stacking Unit Inclination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coin wrapping machines experience stacking failures due to coins becoming increasingly horizontal, leading to disorder and incomplete wrapping, as they catch and shift during stacking, resulting in weak pressing forces and potential bouncing.
Innovation Solution
A coin wrapping machine with a transport unit, stacking unit, stack support portion, inclination maintaining portion, and wrapping unit, where the stack support portion inclines coins and the inclination maintaining portion ensures they remain upright, preventing horizontal shifting and bouncing, and a stopper prevents coins from escaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If coins are stacked while inclined in the stacking unit, then coins can be aligned without stacking disorder, but coins shift horizontally and become increasingly horizontal toward the upper side as stacking progresses
Solution Approach 1:
The stack support portion is designed to lower automatically as coins are stacked, dynamically adjusting the support position to maintain consistent coin inclination throughout the stacking process. This dynamic adjustment prevents coins from becoming increasingly horizontal and maintains stable inclination for neat wrapping.
Solution Approach 2:
The stack support portion acts as an intermediary element between the stacking unit and the coins. By introducing this intermediate support mechanism that can lower progressively, the system maintains coin inclination stability without requiring direct intervention in the coin stacking process itself.
2Reliability
If coins become increasingly horizontal, then the position of the rear end of stacked coins becomes higher, but coins bounce and cause stacking failure
Solution Approach 1:
The stopper is designed to move upward dynamically as coins are stacked, automatically adjusting its position to maintain optimal contact with the coins. This dynamic adjustment ensures consistent pressing force prevents bouncing, and maintains reliable stacking without coins becoming disordered.
3Manufacturing precision
If the coin stack becomes disordered, then wrapping cannot be performed neatly, but adding more control mechanisms increases device complexity
Solution Approach 1:
The stack support portion and stopper are merged into a coordinated system where both elements work together to maintain coin inclination and prevent bouncing. This combined approach achieves neat wrapping through simple mechanical cooperation rather than multiple independent control mechanisms, avoiding excessive device complexity.
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
Ensures reliable, disorder-free stacking and neat wrapping of coins by maintaining their incline, reducing component count, and evenly spacing coins regardless of diameter, stabilizing the stacking process.
Implementation Method 1
a stack support portion which is provided with an inclined stack support surface on the upper surface, and supports coins stacked in the stacking space in an inclined state by the stack support surface

AI summary
The stacking unit is provided with a stacking space, which accepts coins transported by the transport unit from above and stacks the coins. In the stacking space, stack support portions which support coins to be stacked are provided movably up and down. Coins to be stacked are supported in an inclined state by the stack support portions. At a height in which the stack of coins supported by the stack support portions are stacked, an inclination maintaining portion in which the higher side of the inclination of a coin comes into contact with is provided. The inclinations of coins higher than a space portion are forcibly maintained by the inclination maintaining portion, the space portion being formed on the higher side of the inclination of the coin at a height in the stack of the coins.
