Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing braking systems for sheet production lines, such as those used in corrugated board manufacturing, are cumbersome and slow to adjust when transitioning between different sheet lengths, potentially damaging the sheets and causing production inefficiencies.
Innovation Solution
A shingling device with independently movable sets of braking wheels that adjust to varying sheet lengths, allowing for smooth and efficient braking without damaging the sheets, by positioning the wheels correctly for each production order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If braking brushes are used to slow down sheets, then the sheets can be braked effectively, but the sheets risk being damaged by friction and rubbing
Solution Approach 1:
The patent introduces an intermediary braking mechanism that uses a braking wheel with a compliant surface (such as a rubber or polymer coating) instead of direct brush contact. This intermediary layer reduces friction-induced damage while maintaining effective speed reduction of the sheets during shingling operations
Solution Approach 2:
The invention replaces the traditional mechanical brush-based braking system with a wheel-based system that uses controlled friction through a compliant surface. This substitution reduces the harmful mechanical rubbing action while maintaining the necessary braking function
2Object-affected harmful factors
If braking wheels or rollers are used instead of brushes, then sheet damage is reduced, but the system becomes cumbersome and slow to position when transitioning between different sheet lengths
Solution Approach 1:
The braking wheel system is designed with movable and adjustable positioning capabilities, allowing it to be dynamically repositioned along the conveyor path. This enables quick adjustment of the braking wheel position to accommodate different sheet lengths without requiring complete system reconfiguration, thereby reducing downtime during order transitions
Solution Approach 2:
The braking system is segmented into independently adjustable components, where the braking wheel can be positioned at different locations along the conveyor. This segmentation allows selective positioning of braking elements to match specific sheet length requirements, enabling faster transitions between production orders
3Object-affected harmful factors
If braking wheels are used, then the braking action is gentler on sheets, but the device becomes more complex and cumbersome
Solution Approach 1:
The braking wheel is designed to serve multiple functions: it provides gentle braking through compliant surface contact, can be repositioned for different sheet lengths, and maintains consistent performance across various operating conditions. This multi-functionality reduces the need for multiple specialized components, thereby managing device complexity while achieving gentle effective braking

AI summary
The shingling device comprises: a shingling conveyor, adapted to receive a stream of sheets aligned with one another and not overlapping; a braking device, positioned above the shingling conveyor and configured to slow down the sheets arriving to the shingling conveyor, and to partially overlap the incoming sheets in shingling fashion. The braking device comprises: a first set of braking wheels aligned with one another along a first rotation axis orthogonal to a feed direction of the sheets to the shingling conveyor; and a second set of braking wheels aligned with one another along a second rotation axis orthogonal to the feed direction of the sheets to the shingling conveyor.
