Solution Overview
Problem
Existing sheet processing devices face complications due to curl deformation in sheets, leading to defects and increased manufacturing costs, as mechanisms to prevent curl deformation complicate the device configuration and control.
Innovation Solution
A sheet processing method and device that acquires determination information about the storage state of incoming sheets, providing a curl notification when certain conditions are met, allowing sheets with curl deformation to be routed to appropriate storage units that either do not feed or dispense them, thereby preventing defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a mechanism is added to prevent curl deformation in sheet storage, then curl deformation is reduced, but device complexity and manufacturing costs increase
Solution Approach 1:
The system uses information already available from the storage device (determination information about storage state) to automatically identify and route sheets with curl deformation, without requiring additional active prevention mechanisms in the storage device itself
Solution Approach 2:
The sheet processing device acts as an intermediary that receives determination information from the external storage device and uses this information to route sheets appropriately, separating the detection function from the processing function
2Reliability
If determination information is acquired and curl notifications are provided, then sheets with curl are identified and routed appropriately, but device complexity and control complexity increase
Solution Approach 1:
The system acquires determination information about the storage state before the sheet is processed, allowing proactive identification and routing of sheets with curl deformation before they cause defects in subsequent processing
Solution Approach 2:
The sheet processing device is divided into multiple storage units with different functions (first storage unit for sheets with curl that does not feed sheets, second storage unit for sheets without curl that can feed sheets), allowing appropriate handling based on sheet condition
3Productivity
If sheets with curl deformation are handled by the sheet processing device, then processing capacity is maintained, but defects occur due to curl deformation
Solution Approach 1:
The system performs preliminary identification of sheets with curl deformation by acquiring determination information from the storage device, and routes these sheets to a storage unit that does not feed sheets, preventing defects before they occur during processing while maintaining overall processing capacity
Solution Approach 2:
Different storage units are assigned different functional characteristics based on the sheet condition they handle - the first storage unit is designed not to feed sheets with curl, while the second storage unit is designed to feed sheets without curl, optimizing each unit for its specific purpose

AI summary
A sheet processing method according to the present disclosure is a method that is performed by a sheet processing device that receives a deposit of a sheet, the method including: acquiring determination information in a case where a deposit of the sheet is received from an external storage device, the determination information being information about the storage device where the sheet to be received has been stored; and providing a curl notification that the sheet has a curl in a case where the determination information satisfies a predetermined condition.
