Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium processing apparatuses face challenges in estimating the transition time to a liquid applicable state due to the uncertainty of liquid replenishment in sub tanks, leading to downtime in crimp binding processes.
Innovation Solution
A medium processing apparatus equipped with a liquid detector and controller that adjusts the transition time to a liquid applicable state based on the amount of liquid in the storage tank, ensuring timely liquid application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If liquid is applied to each medium in a sheet bundle, then binding strength is increased, but downtime occurs when the sub tank is liquid absent and the transition time to liquid applicable state cannot be estimated
Solution Approach 1:
The liquid is supplied to the liquid application member in advance before the sub tank is depleted. The controller monitors the liquid amount in the sub tank and initiates liquid supply from the main tank when the liquid level becomes low, ensuring the liquid application member remains saturated and ready for immediate use, thus preventing downtime.
Solution Approach 2:
The controller continuously monitors the liquid amount in the sub tank using a liquid level sensor and adjusts the liquid supply operation accordingly. When the liquid level in the sub tank falls below a threshold, the controller activates the liquid supply mechanism to replenish the sub tank from the main tank, creating a closed-loop feedback system that prevents liquid depletion and ensures continuous operation.
2Device complexity
If the amount of liquid in the sub tank is not monitored, then the liquid application mechanism is simple, but the transition time to liquid applicable state cannot be estimated
Solution Approach 1:
The manual monitoring and estimation of liquid levels and transition times is replaced with an automated electronic detection and control system. A liquid level sensor detects the liquid amount in the sub tank, and a controller processes this information to automatically manage liquid supply, replacing mechanical estimation with electronic measurement and control.
Solution Approach 2:
The controller acts as an intermediary between the liquid storage system and the liquid application member. It receives information from the liquid level sensor about the sub tank's liquid amount and controls the liquid supply valve or pump to maintain adequate liquid levels, mediating the interaction between storage and application components.

AI summary
A medium processing apparatus (3) includes a liquid applier (31) to apply liquid to a part of a medium (P) to perform a liquid application, a medium processing device (25) to perform desired processing on a bundle of media including the medium subjected to the liquid application, a liquid storage (44) to store liquid used for the liquid application by the liquid applier, a liquid detector (43) to detect an amount of liquid in the liquid storage, and a controller (100b) to control a supply operation of supplying the liquid to the liquid applier to set a liquid applicable state in which the liquid applier can apply the liquid to the at least one medium based on information from the liquid detector. The controller changes a transition time to the liquid applicable state, based on the amount of liquid in the liquid storage detected by the liquid detector.
