Coin Sorting Machine Cover and Conveyor Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coin sorting machines require multiple steps to access the coin transport path for maintenance, which is time-consuming and inefficient, especially in case of system malfunctions or jammed coins.
Innovation Solution
Incorporating a delay element between the housing cover and coin conveyor, along with a positioning device that can assume operating, release, and rest positions, allowing rapid access to the coin transport path by moving the housing cover into an open position, and using elastic or mechanical elements for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the housing cover is opened to access the coin transport path, then access to the transport path is possible, but the coin conveyor must first be removed which requires multiple steps and time
Solution Approach 1:
The coin conveyor is designed to be dynamically movable between an operative position (contacting the transport path) and a retracted position (spaced away from the transport path). This dynamic positioning allows the conveyor to be automatically moved out of the way when the housing cover is opened, eliminating the need for manual removal and enabling rapid access to the transport path for maintenance.
2Reliability
If the coin conveyor is continuously pressed against the coin transport path, then reliable coin transport is achieved, but the brush wears out faster reducing service life
Solution Approach 1:
The positioning device enables the coin conveyor to dynamically adjust its position between an operative position where it contacts the transport path for reliable coin conveyance, and a rest position where it is spaced away from the transport path to reduce wear on the brush. This dynamic adjustment allows the system to alternate between high-reliability operation and low-wear standby states.
Solution Approach 2:
The coin conveyor operates in periodic cycles, alternating between an operative position for active coin transport and a rest position for reduced wear. This periodic switching between active and inactive states allows the brush to recover and reduces cumulative wear, thereby extending service life while maintaining transport reliability during active periods.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and safe access to the coin transport path, reducing the number of steps required for maintenance and preventing damage to the machine, while ensuring reliable coin transport and extended brush life.
Implementation Method 1
The pulling element (31) can be elastic and/or designed in such a way that the movement of the housing cover (7) is passed on to the arm (27) with a delay.

AI summary
The invention relates to a coin sorting machine (1) for sorting coins, comprising a housing (4) with an openable housing cover (7) and a coin feeder (9) covered by the housing cover (7) in at least one closed position (S), wherein the coin feeder (9) has at least one coin transport path (19) and at least one coin feeder (21) movable relative to the coin transport path (19) for conveying coins along the coin transport path (19). To facilitate access to the at least one coin transport path (19) from the outside (A), the invention provides that the housing cover (7) is coupled to the at least one coin feeder (21) and that, when the housing cover (7) is in an open position (O), the at least one coin transport path (19) is also open and accessible from outside (A) of the housing (4).
