Rubberized Tag Peeling During Tyre Building Using Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The application of rubberized electronic tags during tyre building negatively affects production cycle time and structural complexity, and existing automated detachment methods are ineffective due to the rubberized tags' light, flexible, and sticky nature, which causes them to follow the continuous band even when changing direction.
Innovation Solution
A method and apparatus using a recirculation section between flat abutment surfaces to gradually detach rubberized electronic tags from a continuous band, employing a longitudinal sliding motion with controlled adhesion forces to ensure efficient and automated peeling without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubberized electronic tags are applied during tyre building, then tyre tracking and monitoring capability is improved, but production cycle time increases and structural complexity increases
Solution Approach 1:
The electronic tags are applied to the tyre during the building process rather than after, allowing parallel processing where tag application occurs while the tyre is being assembled. This preliminary action integrates the RFID tag application into existing tyre building operations, improving productivity without compromising tracking capability
Solution Approach 2:
The system uses the tyre building machinery itself to apply the tags during normal operations, rather than requiring separate dedicated equipment. The existing structural complexity of tyre building equipment is leveraged to perform tag application, avoiding additional structural complexity while maintaining reliability
2Productivity
If automated detachment methods are used for rubberized tags, then application speed is improved, but effectiveness deteriorates due to tag deformation
Solution Approach 1:
The system changes the physical parameters of the continuous band (tension, speed, temperature) to optimize the peeling process. By controlling the band's physical state, tags detach automatically at the correct location without mechanical force that would cause deformation, maintaining both speed and precision
Solution Approach 2:
The system replaces mechanical peeling mechanisms with a thermal or chemical release mechanism. The continuous band uses temperature or chemical changes to release tags automatically, eliminating the need for mechanical peeling forces that would deform the flexible rubberized tags, thus maintaining both productivity and manufacturing precision
3Productivity
If high tag capacity is stored on reels, then apparatus efficiency is improved, but reel size and handling complexity increase
Solution Approach 1:
The system divides the continuous band into manageable sections or layers on the reel, allowing high capacity storage while maintaining simple handling. Each section can be independently managed, reducing the complexity of reel handling even as total capacity increases, thus improving apparatus efficiency without proportionally increasing handling complexity
4Area of stationary object
If continuous band changes direction rapidly, then apparatus compactness is improved, but tag detachment effectiveness worsens
Solution Approach 1:
The system prepares the continuous band in advance by pre-stretching or pre-heating it before it needs to change direction. This preliminary action ensures the band is in the optimal physical state to release tags effectively even during rapid direction changes, maintaining peeling quality while allowing compact apparatus design
Solution Approach 2:
The system dynamically changes physical parameters of the continuous band (temperature, tension, humidity) in response to direction changes. When the band changes direction rapidly, parameters are adjusted to maintain optimal tag release conditions, ensuring detachment effectiveness is maintained regardless of apparatus compactness or direction change speed

AI summary
An apparatus for applying rubberized electronic tags to a tyre being processed. The apparatus has a peeling device defining a sliding path for a continuous band and driving members configured for imposing, on the continuous band, a longitudinal sliding motion along the sliding path with a sliding speed. The continuous band slides along a first abutment body, a recirculation transmission and a second abutment body. The continuous band coming from the first abutment body is first deflected by rotating the direction of the sliding speed of the continuous band and subsequently directed towards the second abutment body.
