Note Handling Device Direct Transport Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling notes of value, such as automated teller machines, require significant installation space for intermediate storage units, which is limited, and slow down the withdrawal process due to the need for intermediate storage of notes before they can be stacked into a wad.
Innovation Solution
A device with a first transport unit for moving notes between the box area and the head module, and a second transport unit within the head module for direct transport of rejected and non-rejected notes to the reject and retract container, eliminating the need for intermediate storage and allowing simultaneous stacking of notes into a wad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediate storage unit is used to store notes before stacking, then sorting out rejected notes can be performed, but installation space is consumed and withdrawal time is increased
Solution Approach 1:
The patent extracts the intermediate storage function from the system by implementing direct transport paths. Rejected notes are immediately diverted to the reject container via the first switch without being stored in an intermediate storage unit, while good notes are directly transported to the stacking unit. This eliminates the need for a separate intermediate storage component, saving installation space while maintaining sorting capability.
Solution Approach 2:
The transport system is segmented into multiple independent paths: a first transport unit for good notes to the stacking unit, and a second transport unit for rejected notes to the reject container. The first switch segments the flow of notes, directing them to different destinations based on their status. This segmentation allows simultaneous processing of good and rejected notes without requiring a shared intermediate storage space.
2Reliability
If an intermediate storage unit is used to store notes before stacking, then sorting out rejected notes can be performed, but the withdrawal operation is slowed down
Solution Approach 1:
The patent implements continuous transport of notes through the first and second transport units. Good notes are continuously fed to the stacking unit while rejected notes are simultaneously and continuously diverted to the reject container. This eliminates the intermittent storage and retrieval cycles associated with intermediate storage units, maintaining continuous useful action throughout the sorting and stacking process, thereby reducing withdrawal time.
Solution Approach 2:
The first switch performs preliminary sorting action at the point where notes arrive from the cash box. By immediately directing rejected notes to the second transport unit before they reach any storage point, the system performs the sorting action in advance, preventing rejected notes from entering the stacking process. This preliminary action eliminates the need for later rejection handling and speeds up the overall withdrawal operation.
3Area of stationary object
If a separate transport path for rejected notes is implemented, then intermediate storage can be eliminated, but transport unit complexity increases
Solution Approach 1:
The second transport unit is designed with multi-functionality to handle both rejected notes and the stacked wad of good notes. It can transport rejected notes from the first switch to the reject container, and subsequently transport the completed wad from the stacking unit to the output compartment. This universal transport unit reduces the need for separate dedicated transport mechanisms for different note types, managing complexity through functional consolidation rather than proliferation of components.

AI summary
A device (10) for handling notes of value has a box receiving area (14) for receiving cash boxes (18) and a first transport unit (22) for transporting of notes of value between the cash boxes (18) and a head module (12). A first switch (50) is provided at a head module side-end of the first transport unit (22). Further, the device (10) has a stacking unit (26), an input and/or output compartment (28) and a reject and retract container (30). In addition, a second transport unit (24) for transporting notes of value between the stacking unit (26), the input and/or output compartment (28) and the reject and retract container (30) is provided. In a first switch position, the first switch (50) guides a note of value removed from the box receiving area (14) to the stacking unit (26) and in a second switch position to the second transport unit (24).
