Tape Binding Positioning for Sheet Stack Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive tape binding methods for sheets result in uneven stacks due to tape thickness, leading to balance issues and potential collapse, and adjacent tapes adhering to each other, making bundles difficult to handle individually.
Innovation Solution
A sheet processing device with a tape binding processing unit and control unit that strategically positions tape binding portions on sheets to prevent contact between adjacent bundles, ensuring balanced stacking and preventing tape adhesion between bundles by spacing tape binding portions in the sheet width direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive tape binding is used to bind sheets together, then the sheets can be bound without leaving holes, but the stack height increases in the periphery where tape binding is present, causing balance deterioration and potential collapse
Solution Approach 1:
The patent applies dimensionality change by shifting the tape binding position from the traditional edge location to an inner position along the conveyance direction. This dimensional repositioning moves the binding away from the peripheral region, preventing the tape thickness from causing stack height variation at the edges and thereby maintaining stack balance and stability.
2Ease of manufacture
If adhesive tape binding is used to bind sheets together, then the sheets can be bound without leaving holes, but the adhesive layers of adjacent bundles may adhere to each other, making bundles hard to handle individually
Solution Approach 1:
The patent applies dimensionality change by repositioning the tape binding from the edge to an inner location along the conveyance direction. This spatial relocation ensures that when bundles are stacked, the tape binding portions do not contact each other, preventing adhesive transfer between adjacent bundles and maintaining ease of individual handling.
3Device complexity
If tape binding portions are positioned at the edge of sheets, then binding is simple, but adjacent tape binding portions contact each other in stacked bundles, causing adhesive adhesion between bundles
Solution Approach 1:
The patent applies dimensionality change by moving the tape binding position from the edge (peripheral dimension) to an inner position along the conveyance direction. This spatial repositioning creates separation between adjacent tape binding portions in stacked bundles, eliminating contact and preventing adhesive adhesion between bundles while maintaining simple binding implementation.

AI summary
A sheet processing device includes a tape binding processing unit, a paper discharge unit, and a control unit. The tape binding processing unit performs tape binding processing on a sheet bundle. The paper discharge unit discharges the sheet bundle subjected to the tape binding processing onto a paper discharge tray. The control unit is configured to control at least one of the tape binding processing unit and the paper discharge unit, such that a first tape binding of the first bundle of sheets and a second tape binding of the second bundle of sheets are not in contact with each other when the first bundle of sheets and the second bundle of sheets are stacked on the paper discharge tray.
