Integrated Sheet Creasing and Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet processing systems require significant space and energy for creasing operations due to separate alignment correction and creasing mechanisms, leading to inaccuracies and inefficiencies in folding and binding processes.
Innovation Solution
Integrating a creasing mechanism within post-processing units like punching, binding, or folding units, using a shared alignment correcting mechanism to perform both sheet alignment and creasing, eliminating the need for a separate creasing device and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate creasing device is used for creasing operations, then creasing can be performed independently, but the device occupies significant space and consumes excessive energy
Solution Approach 1:
The patent combines the creasing mechanism with the post-processing unit (punching, binding, or folding unit) into a single integrated device. The creasing mechanism shares the same sheet conveyance path and alignment correcting mechanism as the post-processing functions, eliminating the need for a separate creasing device and reducing overall device footprint while maintaining operational independence through sequential processing steps
2Adaptability or versatility
If separate alignment correction and creasing mechanisms are used, then each function can be optimized independently, but power consumption increases and accuracy decreases
Solution Approach 1:
The alignment correcting mechanism is designed as a universal component that serves both the creasing operation and the post-processing operations (punching, binding, folding). By using a single multi-functional alignment mechanism rather than separate mechanisms for each function, the patent reduces power consumption while maintaining the ability to optimize alignment for different operations through controlled adjustment
3Ease of operation
If separate alignment correction and creasing mechanisms are used, then each function can be independently controlled, but accuracy becomes uneven due to error accumulation
Solution Approach 1:
By merging the alignment correction and creasing functions into a single integrated mechanism with a shared alignment correcting component, the patent eliminates the interface between two separate systems. This single integrated control path prevents error accumulation that would occur with multiple independent mechanisms, ensuring consistent and accurate positioning for both creasing and post-processing operations

AI summary
A sheet processing apparatus includes: a correcting unit that corrects alignment of a sheet; a post-processing unit that performs post-processing on the sheet after the correcting unit corrects the alignment of the sheet; and a creasing unit that forms a crease on the sheet after the correcting unit corrects the alignment of the sheet.
