Liquid Applier with Retained Amount Detector for Sheet Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing apparatuses face difficulties in maintaining binding strength when crimping a large number of sheets, as the binding teeth struggle to bite into the sheet bundle, leading to potential sheets peeling off, and existing solutions like liquid application do not effectively address this issue.
Innovation Solution
A medium processing apparatus comprising a conveyor, a liquid applier, and a crimper, where the liquid applier applies a controlled amount of liquid to the binding position using a liquid application member and a retained liquid amount detector, ensuring optimal liquid retention for improved binding strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If liquid is applied to the binding position to enhance binding strength, then the binding strength is improved, but the liquid amount control is insufficient causing inconsistent binding quality
Solution Approach 1:
The patent employs a feedback mechanism where a liquid amount detector measures the actual liquid amount on the binding position and feeds this information back to the liquid applier. The liquid applier adjusts its operation based on this feedback to maintain the liquid amount within a predetermined range, ensuring consistent binding quality.
Solution Approach 2:
The system dynamically adjusts the liquid application parameters (amount, timing) based on detected conditions. The liquid amount detector monitors the liquid state and the controller modifies the liquid applier's operation parameters to optimize binding strength while maintaining precise control.
2Productivity
If the number of sheets in the sheet bundle is increased, then the productivity is improved, but the binding teeth cannot bite into the sheet bundle effectively causing sheets to peel off
Solution Approach 1:
The liquid is applied to the binding position before the crimping operation. This preliminary action prepares the sheet surface by applying liquid that enhances the binding teeth's ability to bite into the sheets, ensuring effective binding even when processing large bundles with many sheets.
Solution Approach 2:
The liquid acts as an intermediary substance between the binding teeth and the sheet bundle. It modifies the interaction at the binding interface, reducing friction and enabling the binding teeth to penetrate and grip the sheets more effectively, thereby maintaining binding strength in large sheet bundles.
3Strength
If more liquid is applied to ensure binding strength, then the binding strength is improved, but the liquid waste increases and drying time increases
Solution Approach 1:
The liquid amount detector provides real-time feedback on the actual liquid amount applied. This feedback enables the controller to adjust the liquid applier's operation to maintain liquid amount within an optimal range, preventing both insufficient binding and excessive liquid application that would cause waste and extended drying times.
Solution Approach 2:
The system optimizes liquid application parameters (amount, timing, distribution) based on detected conditions and predetermined ranges. By precisely controlling these parameters, the system achieves effective binding strength while minimizing liquid waste and optimizing drying time.
