Sheet Bundle Finisher With Movable Stapler and Eco-Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing finishers for binding sheet bundles lack a unified mechanism that can efficiently bind sheets on a processing tray and external casing, and there is a need for a versatile binding device that can handle both staple and non-staple binding methods.
Innovation Solution
A finisher with a conveying portion, tray, insertion portion, stapler, and stapler moving mechanism that allows for binding at multiple positions, including corner binding and eco-binding, using both staples and non-staple methods, with a structure that integrates both internal and external sheet bundle handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stapling unit is used to bind sheet bundles, then reliable bonding is achieved, but the apparatus becomes more complex and requires additional components
Solution Approach 1:
The binding apparatus integrates both a stapling unit and a press binding unit into a single device, allowing it to perform both staple-based binding and non-staple press binding. This multi-functional design enables the apparatus to achieve reliable bonding through staples when needed, while also offering eco-friendly press binding as an alternative, thereby maintaining high reliability without requiring separate dedicated devices for each binding method
2Device complexity
If a press binding unit is used to bond sheets, then the apparatus is downsized and eco-friendly, but the bonding reliability decreases
Solution Approach 1:
The binding apparatus combines both press binding capability and stapling capability in one integrated device. The press binding unit provides downsized, eco-friendly binding for typical documents, while the integrated stapling unit serves as a backup or alternative for cases requiring higher bonding reliability, thus achieving both compact size and dependable bonding without compromise
3Adaptability or versatility
If multiple binding methods are integrated in one apparatus, then versatility is improved, but the device complexity increases
Solution Approach 1:
The apparatus is designed with both a stapling unit and a press binding unit integrated into a single device structure, enabling it to perform multiple binding methods (staple binding, corner binding, and eco-binding) without requiring separate dedicated devices. This multi-functional integration achieves high versatility while managing device complexity through shared structural components and coordinated control mechanisms

AI summary
A finisher for binding a sheet bundle includes a conveying portion configured to convey a sheet; a tray configured to stack the sheet conveyed by the conveying portion one by one for forming the sheet bundle; an insertion portion to which the sheet bundle is configured to be inserted by an operator; a stapler, configured to bind the sheet bundle by a staple, and having a head at a front portion of the stapler for binding the sheet bundle, and a cartridge at a rear portion of the stapler for containing the staple; and a stapler moving mechanism configured to move the stapler to a first stapling position for binding a corner portion of the sheet bundle, a second stapling position for binding the sheet bundle inserted into the insertion portion, and a staple loading position for removing the cartridge and replenishing a new cartridge.
