Vacuum Holding Head for Green Tire Transponder Strip Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual application of transponder units in tires, particularly in large-format tires for off-the-road and agricultural vehicles, is difficult, time-consuming, and ergonomically unsuitable, posing safety risks and durability issues due to high stress and potential destruction of electronics during vulcanization.
Innovation Solution
A device and method for automated insertion of a holding strip with a transponder unit into a green tire using a holding head with suction pads and pressure rollers, allowing for precise placement and attachment to the tire's inner layer, with a separating strip preventing adhesion during vulcanization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual application of holding strip and separating strip is used, then flexibility and adaptability are maintained, but productivity is reduced and ergonomic risks increase
Solution Approach 1:
The holding strip applies adhesive to itself through the adhesive application roller, and the separating strip is automatically positioned and applied during the same operation. The system serves itself by integrating multiple functions into a single automated device, eliminating manual intervention and improving productivity while maintaining precision.
Solution Approach 2:
The application device combines multiple functions: holding strip application, adhesive application, and separating strip positioning all in one device. This multi-functional approach replaces multiple manual operations with a single automated system, significantly improving productivity and eliminating ergonomic issues associated with manual handling.
2Productivity
If automated application device is introduced, then productivity and ergonomics are improved, but device complexity increases
Solution Approach 1:
The patent merges the holding strip application mechanism, adhesive application roller, and separating strip positioning system into a single integrated device. By combining these functions rather than using separate automated systems, the patent reduces overall device complexity while maintaining high productivity and ergonomic benefits.
3Ease of manufacture
If separating strip is applied during green tire assembly, then transponder unit insertion is enabled after vulcanization, but manufacturing precision is challenged by tire curvature
Solution Approach 1:
The holding strip and separating strip are applied to the green tire before vulcanization, when the tire is still accessible and the mounting surface is prepared. This preliminary action enables subsequent transponder unit insertion after vulcanization without compromising placement accuracy, as the strips are securely attached during the easier green tire stage.
Solution Approach 2:
The adhesive acts as an intermediary between the holding strip and the green tire mounting surface, ensuring precise and secure placement even on curved surfaces. The adhesive application roller applies adhesive uniformly, creating a reliable bond that maintains positioning accuracy throughout the vulcanization process and enables subsequent transponder insertion.

AI summary
The invention relates to a device for the automated picking up and insertion of a holding strip (2) of a transponder unit into a green tire, wherein the holding strip (2) is formed by an elongated rubber section with two end regions (20, 21) and a through-opening (23) formed between the end regions (20, 21) and is underlaid with a separating strip (3) running transversely to the rubber section in the region of the through-opening (23), wherein the device comprises a holding head (1) having first suction stamps (10) which are arranged and configured such that they can each be placed on an end region (10, 21) of a provided holding strip (2) in a placement direction (R) in order to suck the holding strip (2) upon application of a negative pressure, and a second suction stamp (11) is provided between the first suction stamps (10), which is arranged and configured such thatthat, with the first suction stamps (10) placed on the holding strip (2), it can be placed on the through-opening (23) of the holding strip (2) in order to suck the underlying separating strip (3) through the through-opening (23) of the holding strip (2) upon application of a negative pressure. Furthermore, a method for the automated picking up and insertion of a holding strip (2) of an electromagnetic transmitting and receiving device into a green tire using such a device is also specified.
