Contact Element for Orderly Note Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing note stacking devices result in disorderly stacks due to uncontrolled movement of notes after removal from transport tongues, leading to inefficiencies and increased error proneness.
Innovation Solution
A device with a contact element that moves with the note of value from the transport tongue to the deposit surface, utilizing gravity for controlled placement and including a pivotable and frictionless design to ensure accurate stacking without adhesion, along with sensor units for jam prevention and a press-on element for stack compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notes of value are removed from transport tongues without additional control elements, then the stacking process is simple, but the notes move in an uncontrolled manner in free fall resulting in disorderly stacks
Solution Approach 1:
A contact element is introduced as an intermediary between the transport tongue and the deposit surface. This contact element guides the note of value during its movement from the transport tongue to the deposit surface, preventing uncontrolled free fall while maintaining a relatively simple overall device structure. The contact element acts as a mediator that provides the necessary control without requiring complex mechanisms.
2Manufacturing precision
If actuators are used to control note movement, then precise positioning is achieved, but error proneness increases and installation space is required
Solution Approach 1:
The contact element is designed to be passively actuated by the note of value itself during the stacking process. As the note moves from the transport tongue, it naturally interacts with the contact element, which guides it to the correct position on the deposit surface without requiring external actuators. This self-service mechanism achieves precise placement while eliminating the need for additional active components and installation space.
Solution Approach 2:
The contact element is positioned and dimensioned such that the note of value moves along it under the influence of gravity alone, without requiring additional forces or actuators. The geometry of the contact element creates a natural guidance path that ensures precise positioning while maintaining a passive, actuator-free system.
3Reliability
If a contact element is introduced to control note movement, then orderly stacking is achieved, but the risk of note adhesion to the contact element increases
Solution Approach 1:
The contact element is covered with a thin film material that has low friction and non-adhesive properties. This thin film coating allows the note of value to slide smoothly along the contact element during the stacking process, preventing adhesion while maintaining the guiding function of the contact element.
4Ease of operation
If the contact element is made frictionless to prevent adhesion, then note sliding is improved, but control over note placement may be reduced
Solution Approach 1:
The thin film coating on the contact element provides a balance between low friction for smooth sliding and sufficient guidance for accurate placement. The film allows the note to slide easily while the geometric configuration of the contact element maintains control over the note's trajectory and final position.
Solution Approach 2:
The contact element features curved surfaces that guide the note of value smoothly from the transport tongue to the deposit surface. The curvature is designed to maintain contact and guidance throughout the movement, ensuring both smooth sliding and accurate placement. The curved geometry naturally directs the note to the correct position without requiring high friction.

Function Achieved in This Case
The solution ensures reliable, orderly stacking of notes, reduces error proneness, and conserves space by using gravity and a frictionless contact element, while the sensor units prevent jams and the press-on element increases storage capacity.
Implementation Method 1
after the removal of the note of value from the transport tongue, up to the arrival of the note of value on the deposit surface or on the upper note of value of a value note stack deposited on the deposit surface, the contact element and the note of value move in deposit direction with the aid of gravity

AI summary
A device for stacking notes of value includes at least one circulating belt arrangement including an endless belt guided over rollers serving as deflecting elements. The circumferential surface of the belt has at least one transport tongue into which at least a section of a note of value is insertable. The device includes at least one strip-off element that contacts the note for the removal from the transport tongue. The device includes a contact element which is arranged and configured such that during the transport in the transport tongue the note moves the contact element into a first position. The contact element contacts an area of the note at least after the removal of the note of value from the transport tongue up to the arrival of this note on the deposit surface or on the upper note of value of a value note stack deposited on the deposit surface.
