AGV Roll Holder Detection for Sheet Winding Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated guided vehicles (AGVs) face the risk of damaging rolls when entering sheet winding devices due to potential entanglement with hanging sheets, which existing technologies fail to adequately prevent.
Innovation Solution
The AGV is equipped with a roll holder, a detector to acquire information on passage regions, and an illuminator to emit illumination light, allowing it to detect and avoid hanging sheets, thereby preventing damage during entry into sheet winding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the automated guided vehicle enters the sheet winding device to perform roll exchange, then the productivity is improved, but the roll may get damaged due to entanglement with hanging sheets
Solution Approach 1:
The system performs preliminary detection of hanging sheets using the detector before the AGV enters the sheet winding device. The controller receives detection results and controls the AGV to avoid entering when hanging sheets are present, preventing roll damage before it can occur.
Solution Approach 2:
The detector and controller act as intermediaries between the AGV and the sheet winding device. The detector identifies hanging sheets and the controller processes this information to make decisions about AGV entry, mediating the interaction to prevent harmful contact.
2Reliability
If the automated guided vehicle is equipped with detection and illumination systems, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The detector serves multiple functions: it detects hanging sheets, provides detection results to the controller, and enables the system to make informed decisions about AGV entry. The illumination unit supports the detector by providing light for accurate detection, creating a multi-functional detection system.
Solution Approach 2:
The detector provides feedback information about hanging sheets to the controller. The controller receives this feedback and uses it to control whether the AGV should enter the sheet winding device, creating a closed-loop feedback system that improves reliability.
