Sheet Folding Controller Mixed Size Job Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet processing apparatuses cannot effectively handle mixed size jobs requiring sheets of different sizes and equal-size jobs, leading to inconsistent output results as users cannot determine which sheets to fold and which not to fold.
Innovation Solution
A system with a controller that inhibits folding of smaller sheets when a larger sheet is present in a set and permits folding of smaller sheets when no larger sheets are included, allowing for flexible post-processing of sheets of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If folding processing is applied to all sheets regardless of size, then processing uniformity is improved, but output consistency deteriorates because sheets of different sizes cannot be properly handled in mixed size jobs
Solution Approach 1:
The control unit applies different folding processing rules to different sheet sizes within the same set. Specifically, when a set contains sheets of multiple sizes, the system identifies the largest size and applies folding processing only to sheets of that size, while leaving smaller sheets unfolded. This local differentiation resolves the contradiction by maintaining processing uniformity for sheets of the same size while ensuring output consistency across mixed size jobs.
2Manufacturing precision
If folding processing is inhibited for sheets of second size when sheets of first size are present, then output consistency is improved, but processing versatility deteriorates
Solution Approach 1:
The system dynamically adjusts its folding processing behavior based on the composition of the sheet set. The control unit continuously evaluates whether sheets of different sizes are present and automatically switches between two modes: (1) when multiple sizes are detected, it inhibits folding for smaller sheets to maintain output consistency; (2) when only one size is present, it permits folding for all sheets to maintain processing versatility. This dynamic adaptation resolves the contradiction between output consistency and processing versatility.
3Ease of operation
If the system permits flexible folding control for mixed size jobs, then user satisfaction is improved, but system complexity increases
Solution Approach 1:
The control unit automatically determines the appropriate folding processing strategy without requiring user intervention. It self-evaluates the sheet size composition and autonomously decides whether to apply or inhibit folding processing for each sheet size category. This self-service capability provides users with flexible and satisfactory output results while avoiding the complexity of manual configuration interfaces or multiple control modes that would burden the user.

AI summary
There is a disclosure of a system which controls a folding unit performing folding processing to one set of sheets supplied by a print unit. The one set of sheets includes sheets of a first size and/or a second size which is smaller than the first size. The system includes a first controller and second controller. When the one set of sheets includes a sheet of the first size, the first controller inhibits the folding processing to a sheet of the second size. When the one set of sheets does not include a sheet of the first size but includes a sheet of the second size, the second controller permits the folding processing to a sheet of the second size.
