Stapleless Binding Device Sheet Stack Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stapleless binding devices in image forming apparatuses face issues with sheet stack irregularities and displacement during the binding process, leading to reduced productivity due to the need to clamp and hold the stack before backward movement, which disrupts the binding operation.
Innovation Solution
A stapleless binding device with a holding unit that secures the sheet stack during backward movement, combined with a moving unit that relocates the binding unit or stack along guide rails, ensuring consistent binding without staples and minimizing displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stapleless binding unit makes forward and backward movements to perform binding operation, then the binding function is achieved, but the sheet stack experiences displacement and irregularities
Solution Approach 1:
The holding unit is activated before the stapleless binding unit performs its backward movement to preliminarily secure the sheet stack in position. This preliminary action prevents displacement during the binding operation, ensuring the sheet stack remains stable while the binding unit moves forward and backward to create the binding irregularities.
2Stability of the object's composition
If the sheet stack is clamped and held before backward movement to prevent displacement, then sheet stack stability is improved, but the binding operation efficiency is reduced
Solution Approach 1:
The holding unit is designed to be dynamically activated only during the backward movement phase of the binding operation, rather than being continuously engaged. This dynamic operation allows the sheet stack to remain stable when needed while avoiding unnecessary clamping that would reduce binding efficiency and productivity.
3Manufacturing precision
If the moving unit relocates the binding unit or stack along guide rails, then binding position consistency is improved, but the device complexity increases
Solution Approach 1:
Guide rails are introduced as an intermediary mechanism to enable precise movement of the stapleless binding unit along a defined path. These guide rails provide a simple yet effective means of ensuring consistent binding positions without requiring complex positioning systems, thereby achieving manufacturing precision with minimal added complexity.

AI summary
A stapleless binding device includes a stapleless binding unit that performs a stapleless binding operation to form irregularities in a sheet stack by making forward and backward movements, a moving unit that relatively moves the stapleless binding unit or the sheet stack in a direction along one side of the sheet stack, and a holding unit that holds the sheet stack during the backward movement of the stapleless binding unit. The holding unit holds the sheet stack during the backward movement of the stapleless binding unit before the moving unit moves the stapleless binding unit or the sheet stack.
