Post-Processing Drive Heating for Moisture-Induced Sheet Curling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet-type image forming apparatuses experience sheet curling due to moisture in the sheets after image formation, which conventional post-processing apparatuses fail to address effectively.
Innovation Solution
A sheet processing system with a drive portion and supply processing portion that supplies current to drive components outside the execution period of output processing to generate heat and reduce moisture-related defects, using specific currents to enhance heating before and during output processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current is supplied to the drive portion during output processing execution period, then the post-processing apparatus can operate normally, but moisture-related defects such as sheet curling occur
Solution Approach 1:
The supply processing portion supplies current to the drive portion in advance during the idle period before output processing begins. This preliminary action allows the post-processing apparatus to generate heat and evaporate moisture from sheets before they undergo output processing, preventing sheet curling and other moisture-related defects while maintaining normal operation during processing
2Object-affected harmful factors
If current is supplied to the drive portion before output processing, then moisture is reduced and sheet curling is suppressed, but energy is consumed during idle period
Solution Approach 1:
The system implements periodic action by supplying current to the drive portion only during idle periods between batches of output processing, rather than continuously. The supply processing portion detects when the image forming apparatus has completed image formation and supplied sheets to the post-processing apparatus, then supplies current during this idle period to evaporate moisture, and stops current supply when output processing begins. This periodic operation reduces energy consumption compared to continuous operation while still effectively preventing sheet curling

Function Achieved in This Case
The system effectively suppresses sheet curling by accelerating drying through controlled heating, reducing moisture-induced defects in post-processing apparatuses.
Implementation Method 1
a drive portion provided in a post-processing apparatus configured to execute predetermined post-processing on a sheet conveyed from an image forming apparatus configured to form an image on the sheet, and configured to generate a driving force to be transmitted to a constituent member of the post-processing apparatus in response to supply of a current
Implementation Method 2

AI summary
A sheet processing system includes a drive portion and a supply processing portion. The drive portion is provided in a post-processing apparatus configured to execute predetermined post-processing on a sheet conveyed from an image forming apparatus configured to form an image on the sheet, and generates a driving force to be transmitted to a constituent member of the post-processing apparatus in response to supply of a current. The supply processing portion supplies a current to the drive portion from arrival of a predetermined specific timing outside an execution period of output processing for outputting the sheet after image formation using the image forming apparatus and the post-processing apparatus until start of the output processing.
