Solution Overview
Problem
Existing water-containing substance detection devices inaccurately identify the conveyor surface as a water-containing substance and only detect the outermost surface of rubbery polymers, leading to limited product quality enhancement.
Innovation Solution
A water-containing substance detection device with a conveyor having a surface emissivity of 0.50 or more and a temperature sensor with a frame rate of 5 Hz to 120 Hz, positioned near and downstream of the ejection port, to accurately detect water-containing rubbery polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an infrared sensor is used to detect water-containing substances, then detection capability is provided, but the conveyor surface is erroneously recognized as a water-containing substance due to lower temperature
Solution Approach 1:
A temperature sensor is introduced as an intermediary device to measure the conveyor surface temperature. This additional measurement allows the system to distinguish between the conveyor surface and water-containing substances by comparing temperature data, thereby eliminating false detections while maintaining the infrared sensor's detection capability
Solution Approach 2:
The system changes the detection parameters by incorporating temperature measurement as an additional criterion. By monitoring temperature variations and comparing them against known conveyor surface temperature ranges, the system can filter out false positives from the infrared detection data, improving both accuracy and reliability
2Productivity
If the processing amount for rubbery polymer is increased, then productivity is improved, but only the outermost surface is detected and water-containing substances are not detected with greater accuracy
Solution Approach 1:
The detection system transitions from two-dimensional surface detection to three-dimensional internal detection by utilizing microwave transmission properties. Microwaves can penetrate through the rubbery polymer material, allowing the system to detect water-containing substances within the bulk material rather than just on the surface, thereby maintaining high detection accuracy even at increased processing volumes

AI summary
A water-containing substance detection device that detects a water-containing rubbery polymer, includes a conveyor configured to convey rubbery polymers; and a detector configured to detect the water-containing rubbery polymer among the rubbery polymers, conveyed by the conveyor, by a temperature sensor. The conveyor has a surface with an emissivity of 0.50 or more. The temperature sensor has a frame rate falling within a range of 5 Hz to 120 Hz. The detector detects the water-containing rubbery polymer, near an ejection port of the conveyor, and on a downstream side of the ejection port.
