Staple Removing Device Guide for Closed Booklet Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing staple removing devices are unable to efficiently remove staples from booklets bound in a two-fold bookbinding manner without opening the booklet, as they require a larger depth dimension to align the staple with the wedge-shaped member, which is not feasible with the minimal depth design.
Innovation Solution
A staple removing device with an aligning part and a guide part that guides the fold of the booklet to the aligning part, and a removing part that moves in a direction intersecting with the fold to engage with the crown portion of the staple, allowing for staple removal without opening the booklet by utilizing a guide that includes a tapered shape to align and position the staple correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dimension in the depth direction of the sheet bundle insertion opening is suppressed to the bare minimum, then the device does not become large, but it is not possible to set the staple in a position in which the staple is removed by the wedge-shaped member when the booklet is opened
Solution Approach 1:
The patent changes the approach from opening the booklet (requiring large depth) to keeping it closed and using the guide to position the staple at the fold location. The removing part operates in a direction intersecting with the fold, utilizing the three-dimensional arrangement of the closed booklet to achieve staple removal without increasing device depth.
Solution Approach 2:
The guide acts as an intermediary component that receives the closed booklet and positions its fold against the aligning part. This intermediary positioning mechanism enables the removing part to access and remove the staple at the correct location without requiring the booklet to be opened or the device to have large depth dimensions.
2Ease of operation
If the dimension in the depth direction of the opening in which the booklet is inserted is set to a length within which one side of the opened booklet can enter, then the staple can be aligned with the wedge-shaped member, but the device is enlarged
Solution Approach 1:
Instead of opening the booklet to access the staple (conventional approach requiring large depth), the patent inverts the approach by keeping the booklet closed and using the guide to position the staple at the fold location where it can be accessed by the removing part operating in an intersecting direction.
Solution Approach 2:
The patent utilizes the three-dimensional configuration of the closed booklet, operating in a direction that intersects with the fold rather than requiring linear depth access. This dimensional approach allows staple removal without increasing the depth dimension of the device.

AI summary
A staple removing device includes an aligning part with which a fold of a booklet stitched by a staple having a crown portion and leg portions and folded along an extension direction of the crown portion is brought into contact, a guide part that guides the fold of the booklet to the aligning part; and a removing part having an operating part that moves in a direction intersecting with the fold of the booklet, to engage with the crown portion of the staple that stitches the booklet.
