Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sampling metal strip coils are inefficient and labor-intensive, requiring manual re-tying or transporting coils to a separate station after sampling, which can lead to coil deformation and quality issues.
Innovation Solution
A device comprising a base roller unit, pressure roller units, and a bundle binding device that securely holds the coil during sampling, preventing it from opening and allowing for immediate re-binding, along with a deflection device that achieves elastic deformation to avoid plastic deformation, enabling efficient and safe sampling and re-winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual re-tying or separate tying station is used after sampling, then coil binding can be restored, but processing time increases and labor intensity increases
Solution Approach 1:
The patent combines the sampling operation and re-binding operation into a single integrated device. The binding device with clamping rollers and binding material feeding mechanism is integrated with the sampling station, allowing both operations to be performed sequentially without moving the coil to a separate station, thereby eliminating time loss and manual labor while ensuring reliable coil binding restoration
Solution Approach 2:
The binding device is pre-positioned and ready with binding material before sampling begins. The clamping rollers are already in place to secure the coil, and the binding material feeding mechanism is pre-configured. This preliminary preparation allows immediate re-binding after sampling without delay, resolving the time loss contradiction
2Reliability
If coil is transported to separate tying station after sampling, then binding can be restored, but handling complexity increases and safety risks increase
Solution Approach 1:
The patent integrates the binding restoration function directly into the sampling device. The binding device includes clamping rollers that secure the coil and a binding material feeding mechanism that applies new binding around the coil at the sampling location, eliminating the need to transport the coil to a separate station and thereby reducing handling complexity and safety risks
Solution Approach 2:
The device performs both sampling and re-binding operations on the coil at the same location without requiring external handling or transport. The coil remains stationary on the support rollers throughout the process, and the binding device automatically applies binding material and secures the coil, making the system self-sufficient and eliminating complex manual handling operations
3Ease of operation
If plastic deformation is applied to separate strip beginning from coil, then separation position is improved, but coil quality deteriorates due to permanent deformation
Solution Approach 1:
The patent changes the deformation parameter from plastic (permanent) to elastic (temporary) deformation. The deflection device applies controlled elastic deformation to the strip beginning, allowing it to be temporarily separated from the coil for sampling, then automatically returns to its original position without permanent deformation, thereby maintaining coil quality while still achieving the separation position needed for sampling
4Reliability
If pressure roller unit is added to prevent coil from opening, then safety is improved, but device complexity increases
Solution Approach 1:
The pressure roller unit serves multiple functions: it prevents the coil from opening during sampling, maintains coil stability during the binding operation, and provides continuous support throughout the process. This multi-functional component addresses the reliability need without requiring multiple separate devices, thereby limiting the increase in device complexity
