Sheet Processing Member Selection for Minimum-Movement Position Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing apparatuses face inefficiencies when processing positions differ between consecutive sheets, leading to increased processing time due to the need for the processing tool to move in a direction intersecting the conveyance direction.
Innovation Solution
The apparatus incorporates a conveyance unit, processing unit with multiple members, and a moving unit, controlled by a controller to optimize processing by using the processing member with the minimum movement distance when processing positions differ, and includes standby, avoidance, and movement controls to minimize processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processing tool moves in the width direction to process sheets at different positions, then the sheet can be processed at various positions, but the processing time increases
Solution Approach 1:
The processing tool is divided into multiple independent processing members (first processing member and second processing member) positioned at different locations in the width direction. Each processing member can process sheets independently at its designated position without requiring the entire tool to move, thereby reducing processing time while maintaining the ability to handle various sheet positions
Solution Approach 2:
The processing members are configured to be movable in the conveyance direction while maintaining fixed positions in the width direction. This dynamic configuration allows different processing members to handle different sheet positions dynamically, eliminating the need for time-consuming movements in the width direction
2Device complexity
If a single processing member is used for all positions, then the device structure is simple, but the processing time increases when position changes are needed
Solution Approach 1:
The processing tool is segmented into multiple processing members positioned at different locations, each capable of independent operation. This segmentation increases productivity by allowing parallel or sequential processing at different positions without requiring tool relocation, while the modular design keeps the overall structure manageable
Solution Approach 2:
Multiple processing members are provided, each capable of performing the same processing function but at different positions in the width direction. This multi-functionality allows the system to handle various sheet positions efficiently without requiring complex reconfiguration, as any processing member can process any sheet that reaches its position

AI summary
A apparatus for processing sheets includes: a conveyance unit conveying a sheet; a processing unit provided with processing members processing the sheet along a conveyance direction, and a moving unit moving the processing members in a width direction; and a controller. When a processing position in the width direction to be processed by the processing members is different between a sheet conveyed ahead by the conveyance unit and a subsequent sheet, the controller processes the subsequent sheet by using a processing member having a minimum movement distance from the processing position of the sheet conveyed ahead among the processing members.
