Solution Overview
Problem
Existing methods for aligning loose sheet-like structures, such as banknotes, are inefficient and require manual intervention, as they lack automated solutions for aligning sheets with varying dimensions and orientations within machines that process payment documents.
Innovation Solution
A device comprising a conveying channel with a primary alignment mechanism using stop elements to tilt and align sheets, followed by a secondary alignment section with removal chambers, facilitated by a vibrating conveying system and automated loading, ensures efficient and automatic alignment of sheets with one longitudinal edge resting on the channel floor, allowing for compact stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual alignment methods are used for loose sheet material, then alignment can be achieved, but labor intensity is high and processing efficiency is low
Solution Approach 1:
The device enables automatic alignment of sheet material through self-aligning mechanisms. The sheet material itself interacts with the alignment elements (profile bodies, stop elements) to achieve proper orientation without human intervention. The vibrating channel base facilitates this self-alignment process by creating controlled movements that guide sheets into correct positions automatically.
Solution Approach 2:
The patent replaces manual mechanical alignment operations with an automated mechanical system. Instead of operators physically handling and aligning sheets, the device uses a combination of vibrating mechanisms, profile bodies, and stop elements to automatically orient and position sheet material in the conveying channel.
2Productivity
If automated alignment devices are introduced, then processing efficiency improves, but device complexity increases
Solution Approach 1:
The alignment device is divided into distinct functional sections: a loading section, a conveying channel with primary alignment means (profile bodies), and a secondary alignment section with stop elements. Each segment performs a specific alignment function, allowing the complex task of sheet alignment to be broken down into manageable, modular components that can be independently optimized and maintained.
Solution Approach 2:
The device incorporates a vibrating channel base that creates dynamic, oscillating movements during the alignment process. This dynamic approach allows sheets to be gently agitated and guided into correct positions rather than using complex static mechanical structures. The vibration frequency and amplitude can be adjusted to optimize alignment for different sheet types.
3Manufacturing precision
If the conveying channel width is reduced to accommodate varying sheet dimensions, then alignment precision improves, but the device becomes less versatile
Solution Approach 1:
The device accommodates varying sheet dimensions by changing the operational parameters of the vibration system and the positioning of alignment elements. The vibrating channel base can adjust vibration characteristics, and the profile bodies/stop elements can be positioned at different locations to match different sheet sizes. This allows precise alignment for each sheet type without requiring a completely different channel width.
Solution Approach 2:
The conveying channel and alignment elements are designed with multi-functionality to handle various sheet dimensions. The same profile bodies and stop elements serve multiple purposes: guiding sheets, preventing lateral displacement, and enabling alignment through vibration. The system can process sheets of different sizes using the same basic structure, adjusting only the operational parameters rather than the fundamental geometry.
4Manufacturing precision
If stop elements are added to align sheets, then alignment accuracy improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple alignment functions into integrated elements. The profile bodies serve both as guide elements and as tipping elements that use the sheet's own weight and vibration to achieve alignment. The stop elements are integrated into the channel structure rather than being separate add-on components. This merging reduces the overall number of discrete parts while maintaining high alignment accuracy.
Solution Approach 2:
The device converts potentially harmful forces into beneficial alignment effects. The vibration, which could cause sheets to jump or misalign, is instead used to facilitate the tipping action of profile bodies and help sheets settle into correct positions. The gravitational force that causes sheets to stack haphazardly is converted into a useful alignment mechanism through the controlled tipping action of profile bodies.

AI summary
The invention relates to a device (1) and associated method for aligning loose items of sheet material (2), such as, for example, banknotes. The device comprises a conveying channel (3) in which the items of sheet material (2), standing on one of their long edges or broad edges, are transported through a conveying device in conveying direction (F). During transportation, one or more profiled members (13) act such that those items of sheet material (2) standing on their broad edges are tipped over onto their narrow edges.
