Fold Reinforcing Roller Division Movement for Sheet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing apparatuses lack effective methods to enhance fold reinforcement, leading to inadequate fold line stability and reduced productivity in sheet processing operations.
Innovation Solution
A sheet processing apparatus incorporating a fold reinforcing unit with a fold reinforcing roller that moves in the fold-line direction, executing a division movement mode with reversal return operations to reinforce the fold line, and a control unit that selects between simple and division movement modes based on sheet characteristics and user preferences to optimize fold reinforcement and productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fold reinforcing unit is added to reinforce fold lines, then fold line stability is improved, but device complexity increases
Solution Approach 1:
The fold reinforcing roller is nested within the existing folding unit structure, allowing the reinforcement function to be integrated into the existing device without adding separate external components. The roller is positioned to work in conjunction with the folding mechanism, utilizing the existing structural framework.
Solution Approach 2:
The fold reinforcing roller is designed to automatically engage and reinforce fold lines during the normal folding operation without requiring additional manual intervention or separate reinforcement steps. The system performs the reinforcement function as part of its inherent folding process.
2Stability of the object's composition
If a fold reinforcing roller is used to reinforce fold lines, then fold reinforcement is improved, but productivity decreases due to additional movement operations
Solution Approach 1:
The fold reinforcing roller operates continuously during the folding process, maintaining constant contact with the fold line to provide ongoing reinforcement. The roller moves smoothly along the fold line without interruption, ensuring that the reinforcement action is performed throughout the entire folding operation without requiring separate discrete steps.
Solution Approach 2:
The fold reinforcing roller is designed with dynamic movement capabilities, allowing it to adjust its position and movement speed to match the folding operation. The roller can move in the fold-line direction and reverse when necessary, adapting its motion to the specific folding pattern being performed.
3Stability of the object's composition
If the fold reinforcing roller moves in the fold-line direction with reversal return operations, then fold reinforcement is enhanced, but the time required for reinforcement increases
Solution Approach 1:
The fold reinforcing roller employs periodic reversal return operations, moving along the fold line and then reversing direction to return to a previous position. This periodic motion pattern allows the roller to reinforce different sections of the fold line systematically, ensuring complete coverage through repeated cycles of movement and return.

AI summary
A sheet processing apparatus includes a folding unit, a fold reinforcing unit, and a control unit. The folding unit folds a sheet and forms a fold line thereon. The fold reinforcing unit includes a fold reinforcing roller. The fold reinforcing roller sandwiches the fold line on the sheet formed by the folding unit and moves in a fold-line direction in which the fold line extends. The control unit moves the fold reinforcing roller from a first position close to a first end of the fold line on a first side in the fold-line direction to a second position close to a second end of the fold line on a second side opposite to the first side. The control unit can execute, at this time, a division movement mode including a reversal return operation. The reversal return operation is an operation of reversing a movement direction of the fold reinforcing roller to the first side at a middle portion of the fold line and then returning the movement direction of the fold reinforcing roller to the second side.
