Reversible Conveying Section for Paper Sheet Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet obverse and reverse side arranging devices face inefficiencies due to long feed intervals and potential damage from striking components, particularly when handling consecutive sheets requiring inversion.
Innovation Solution
A device with a reversible conveying section and guiding mechanism that allows for simultaneous sorting and inversion of paper sheets, reducing feed intervals by switching the sorting direction and reversing the conveying path, and using proximity of inlet and outlet sections to facilitate efficient paper sheet orientation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a switchback inverting path is used to invert paper sheets, then paper sheets requiring inversion can be sorted, but the feed interval becomes long and feed rate deteriorates
Solution Approach 1:
The conveying path is divided into multiple sections: a common upstream conveying path, a reversible conveying section with two inlet/outlet sections, and a downstream conveying path. This segmentation allows different paper sheets to be conveyed through different routes simultaneously, enabling inversion of some sheets while maintaining continuous feeding of others.
Solution Approach 2:
The reversible conveying section can dynamically change its conveying direction based on the inversion requirements of paper sheets. By switching between conveying from the first inlet/outlet section and conveying from the second inlet/outlet section, the system adapts to different sorting needs while maintaining continuous operation and short feed intervals.
2Productivity
If a U-turn conveying path is used for paper sheets not requiring inversion, then these sheets can be conveyed efficiently, but the overall system complexity increases
Solution Approach 1:
The conveying paths for inverted and non-inverted paper sheets are merged in the downstream conveying path. Both paths converge to a common output, simplifying the overall system structure while maintaining the ability to handle different paper sheet requirements through the reversible conveying section.
Solution Approach 2:
The reversible conveying section serves multiple functions: it can convey paper sheets requiring inversion from one inlet/outlet section, convey paper sheets not requiring inversion from the other inlet/outlet section, and maintain continuous operation. This multi-functionality reduces the need for separate dedicated paths for different paper sheet types.
3Adaptability or versatility
If conventional inversion mechanisms with striking components are used, then paper sheets can be inverted, but the paper sheets may be damaged
Solution Approach 1:
The invention replaces conventional mechanical inversion mechanisms that use striking components with a reversible conveying system that uses controlled direction changes. Paper sheets are inverted by being conveyed forward and then reversed in direction, eliminating contact with striking components and preventing damage while maintaining the inversion function.
