Liquid Applier Motion for Stable Crimp Binding of Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing apparatuses face issues with unstable liquid application and binding strength in crimp binding due to insufficient liquid supply and peeling of sheets from the bound bundle, particularly when applying liquid to media for crimp binding.
Innovation Solution
A medium processing apparatus with a liquid applier, crimper, and mover, featuring a liquid storage, supply member, and application member, which enhances liquid contact area and stability through a movable design, ensuring consistent liquid application and improved binding strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid is repeatedly applied to the medium by the conventional liquid application unit, then the liquid application frequency increases, but the liquid supply cannot catch up with the application rate, resulting in unstable liquid application
Solution Approach 1:
The liquid supply member is made movable relative to the liquid storage, transitioning between a liquid supply position (immersed in liquid) and a liquid separation position (withdrawn from liquid). This dynamic positioning allows the system to replenish liquid contact area during the separation phase, ensuring continuous liquid supply capability that matches the repeated application frequency while maintaining stable liquid application amounts.
2Quantity of substance
If an increased number of media are bound in the crimper, then the binding capacity increases, but the binding teeth cannot bite into the sheet bundle properly, causing sheets to peel off
Solution Approach 1:
Liquid is applied to the sheet bundle at a position where the binding teeth will contact the media, before the crimping action occurs. This preliminary liquid application softens the media at the binding location, allowing the binding teeth to bite into the sheet bundle effectively even when binding a large number of media, thereby preventing sheet peeling and maintaining strong binding.
3Reliability
If the liquid supply member maintains constant contact with the liquid storage, then liquid is always available, but the liquid application member cannot be quickly moved between application and separation positions
Solution Approach 1:
The liquid supply member is designed to move dynamically between immersed and withdrawn positions relative to the liquid storage. During the liquid separation position, the contact area is minimized allowing quick movement. During the liquid supply position, the contact area is maximized ensuring liquid availability. This dynamic adjustment resolves the contradiction between maintaining liquid availability and enabling fast movement between positions.

AI summary
A medium processing apparatus includes a liquid applier, a crimper, and a mover. The liquid applier applies liquid on a medium. The crimper crimps and binds multiple media including the medium with the liquid applied. The mover moves the liquid applier. The liquid applier includes a liquid storage, a liquid supply member, a liquid application member, and a liquid supply facilitator. The liquid supply member has first and second ends. The liquid application member is attached to the second end of the liquid supply member. The liquid application member contacts the medium to apply the liquid onto the medium. The liquid supply facilitator increases a contact area between the liquid supply member and the liquid in the liquid storage, in response to a movement of the liquid applier. The mover moves the liquid applier between an application position and a separation position.
