Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet binding devices lack the ability to dynamically adjust the shift amount between sheets in a bundle based on various parameters such as sheet thickness, type, binding number, alignment state, tape type, attachment position, and binding strength, leading to inconsistent adhesive force and unreliable binding.
Innovation Solution
A sheet binding device equipped with a sheet shift section, a tape attaching section, an information acquisition section, and a controller that adjusts the shift amount between sheets based on acquired information, allowing for customizable binding strength and form adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed shift amount is used for all sheets, then the device complexity is reduced, but the binding reliability and adhesive force consistency deteriorate
Solution Approach 1:
The sheet shift section is designed to dynamically adjust the shift amount between sheets based on detected parameters such as sheet thickness, tape type, and binding method. This dynamic adjustment capability allows the device to optimize binding reliability for different sheet conditions without requiring multiple fixed configurations, thereby improving reliability while keeping the device structure relatively simple.
Solution Approach 2:
The controller changes the shift amount parameter based on information acquired by the information acquisition section about sheet properties, tape characteristics, and binding requirements. By varying this key parameter adaptively, the system achieves reliable binding across diverse conditions without increasing fundamental device complexity.
2Strength
If the shift amount is increased to improve adhesive force, then the binding strength is improved, but the appearance quality of the sheet bundle deteriorates
Solution Approach 1:
The system dynamically determines the optimal shift amount by considering multiple factors including sheet thickness, tape type, and desired binding strength. This dynamic optimization ensures that the shift amount is increased only when necessary for binding strength, while maintaining appearance quality when smaller shifts are sufficient, thus resolving the contradiction between strength and appearance.
Solution Approach 2:
The controller adjusts the shift amount parameter based on acquired information about sheet and tape properties, optimizing the balance between binding strength and appearance. By changing this parameter adaptively rather than using a fixed value, the system achieves strong binding when needed while preserving appearance quality when possible.
3Shape
If the shift amount is decreased to improve appearance quality, then the appearance quality is improved, but the adhesive force and binding strength deteriorate
Solution Approach 1:
The sheet shift section dynamically adjusts the shift amount based on detected parameters such as sheet thickness, tape adhesion properties, and binding requirements. This ensures that when appearance quality is prioritized, smaller shift amounts are used, while when binding strength is critical, the system automatically increases the shift amount to ensure sufficient adhesive force, thus resolving the contradiction adaptively.
Solution Approach 2:
The controller modifies the shift amount parameter based on information about sheet properties and tape characteristics, optimizing the balance between appearance and adhesive force. This parameter adaptation allows the system to use minimal shifts for appearance-critical applications while ensuring adequate adhesive force through increased shifts when binding strength is paramount.
4Productivity
If manual adjustment of shift amount is used, then the device complexity is reduced, but the productivity and binding consistency deteriorate
Solution Approach 1:
The information acquisition section automatically detects sheet properties, tape characteristics, and binding conditions, and the controller autonomously determines the appropriate shift amount based on this information. This self-service capability eliminates the need for manual adjustment while maintaining simple device architecture, thereby improving productivity and binding consistency without significantly increasing device complexity.
Solution Approach 2:
The system incorporates feedback through the information acquisition section that gathers data about sheet and tape properties, which the controller uses to automatically adjust the shift amount. This feedback mechanism enables consistent, high-speed operation with optimized binding parameters, improving productivity while keeping the device structure relatively simple through automated control logic.

AI summary
In accordance with an embodiment, a sheet binding device comprises a sheet shift section (ie a sheet shingling section), a tape attaching section, an information acquisition section and a controller. The sheet shift section shifts a plurality of sheets forming a sheet bundle from each other at an edge of the sheet bundle, so that the sheets are shingled. The tape attaching section attaches a tape (having adhesive) to the edge of the sheet bundle. The information acquisition section, which can be an interface or a sensor, acquires information relating to at least one of the plurality of the sheets, the tape, and a binding method of the sheet bundle by the tape. The controller changes a shift amount between sheets in the plurality of the sheets that is shifted by the sheet shift section based on the information acquired by the information acquisition section.
