Coil Reel Weight Sensing for Vibration-Stable Forming Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forming machines face issues with reliable and trouble-free operation due to uneven weight distribution of workpiece reels, leading to vibrations and potential damage, as they lack effective means to detect and balance lateral weight distribution during the feeding process.
Innovation Solution
A device equipped with a weight-distribution sensing system that includes force sensors and a bearing unit to detect lateral weight distribution and imbalance, issuing warnings or stopping the reel rotation if the distribution exceeds a tolerance value, and providing instructions for balancing the coil to ensure even weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a reeling unit is used to accommodate and rotate workpiece coils, then continuous workpiece supply is enabled, but uneven weight distribution causes vibrations and potential damage
Solution Approach 1:
The weight distribution is determined before the reel is rotated for workpiece dispensing. The sensing device detects lateral weight distribution in advance, and the control device issues warnings or balancing instructions before operation begins, preventing vibrations and damage during rotation
Solution Approach 2:
A weight-distribution sensing device continuously or periodically determines the lateral distribution of reel weight with respect to the reel axis. This feedback information is processed by a control device that issues warnings or balancing instructions when uneven distribution is detected, enabling real-time monitoring and correction
2Reliability
If lateral weight distribution is monitored and balancing instructions are provided, then operational reliability is improved, but device complexity increases due to additional sensing and control components
Solution Approach 1:
The patent replaces complex mechanical balancing mechanisms with a sensing device that uses force sensors and a bearing unit to detect lateral weight distribution. The control device then provides electronic warnings or instructions, substituting mechanical adjustment systems with sensor-based monitoring and control

AI summary
A device that feeds an elongated workpiece to a forming machine includes a reeling unit with a frame and a reel carried by the frame and accommodates a workpiece supply formed as a coil of workpiece material. The reel is mounted rotatably about a reel axis relative to the frame. The device has a weight-distribution sensing device set up to sense a lateral distribution of a reel weight with respect to the reel axis, the reel weight representing a weight of the reel with or without an accommodated coil.
