Vertical Load Detector for Milling Roll Stock Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stock level detectors in roll machines for milling suffer from reduced detection precision due to the horizontal application of load on the rod and load cell, causing twisting forces and inaccuracies in weight detection.
Innovation Solution
A stock level detector design featuring a load detector on the inlet part of the tube-type supplying unit with a detection rod suspended within, where one end of the rod is connected to the load detector, and optionally includes a cone part for enhanced load reception, ensuring the load is applied vertically, improving detection precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rod and load cell are connected in L shape with horizontal load application, then the device structure is simplified, but the detection precision deteriorates due to twisting forces at the connection part
Solution Approach 1:
The patent inverts the conventional L-shaped connection configuration by making the rod vertical and the load cell horizontal, so that the load is applied vertically to the load cell rather than horizontally. This inversion eliminates the twisting force problem at the connection part while maintaining structural simplicity.
Solution Approach 2:
The patent employs asymmetric positioning of the rod and load cell, with the rod extending vertically downward from the load cell rather than horizontally. This asymmetric arrangement ensures that the gravitational load on the rod is transmitted vertically to the load cell, preventing twisting moments and improving measurement accuracy.
2Length of moving object
If the rod is made longer to increase detection range, then the detection capability is improved, but the rod becomes more susceptible to twisting forces and vibrations
Solution Approach 1:
By inverting the configuration to vertical rod orientation, the rod's natural stiffness against vertical loading is maximized. The vertical orientation aligns the rod's strongest structural axis with the direction of gravitational force, reducing susceptibility to twisting and vibrations even at longer lengths.
