Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for winding an elongated element of elastomeric material onto a collection reel with a service fabric often result in irregular or uneven winding, leading to waste and defects due to changes in winding conditions and residual tensions, which are not adequately managed by current apparatuses.
Innovation Solution
A method and apparatus that dynamically adjust the rotation speed of the collection reel based on real-time measurements of the actual winding diameter and length of the elongated element, ensuring even winding by synchronizing the feeding speed and tension of both the elongated element and the service fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the collection reel rotates at a constant speed during winding, then the apparatus structure is simple, but the winding becomes irregular and uneven due to changes in winding diameter and element properties
Solution Approach 1:
The collection reel rotation speed is made dynamic rather than constant. The control device continuously adjusts the rotation speed based on real-time detection of winding diameter and elongated element properties, allowing the system to adapt to changing conditions and maintain uniform winding despite variations in material characteristics and reel diameter.
Solution Approach 2:
A feedback control system is implemented where detection devices monitor the actual winding diameter and elongated element properties, and the control device uses this information to adjust the collection reel rotation speed. This closed-loop feedback ensures that winding uniformity is maintained by compensating for changes in material properties and reel diameter.
2Productivity
If the winding speed is increased to improve productivity, then more elongated element is wound per unit time, but residual tensions cause irregular winding and defects
Solution Approach 1:
The rotation speed of the collection reel is dynamically adjusted during the winding process. The control device responds to real-time detection of winding conditions and element properties, allowing the system to optimize speed at different stages of winding to maintain both high productivity and high quality, preventing defects caused by excessive speed.
Solution Approach 2:
The feedback control system monitors winding quality parameters and adjusts the rotation speed accordingly. When the detection devices identify conditions that would lead to defects or irregular winding, the control device reduces the speed to maintain quality, while allowing higher speeds when conditions permit, thus balancing productivity and manufacturing precision.
3Reliability
If the service fabric is wound at the same speed as the elongated element, then the winding process is simple, but the service fabric may not properly prevent sticking when winding conditions change
Solution Approach 1:
The rotation speeds of the collection reel for the elongated element and the service fabric are independently controlled and dynamically adjusted. The control device allows different rotation speeds for the two materials, enabling the service fabric to be applied at optimal speeds to ensure proper sticking prevention, while the elongated element is wound at speeds optimized for its specific properties and winding conditions.
Solution Approach 2:
The feedback control system independently monitors and adjusts the rotation speeds of both the elongated element and service fabric. The detection devices provide real-time information on winding conditions, and the control device uses this to independently optimize the speed of each material, ensuring that the service fabric properly prevents sticking while maintaining overall winding efficiency.
