Tyre Loader Label Transfer for Precise Sidewall Vulcanisation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying decorative labels on tyre sidewalls during vulcanization face issues of repeatability, deformation, increased complexity, and cost due to the need for additional mechanical devices and redesign of vulcanizing and moulding apparatuses, which prolong cycle times and pose safety risks.
Innovation Solution
Utilize a tyre loader to integrate a label transfer member that positions labels in the vulcanization mould using existing loading devices, allowing precise and quick application of labels without additional equipment, ensuring accurate centring and co-vulcanization with the tyre.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a ring-shaped transfer device is used to apply labels during vulcanisation, then label application is achieved, but the vulcanising and moulding process becomes more complex and cycle time increases
Solution Approach 1:
The tyre loader, originally designed solely for loading green tyres into the vulcanisation mould, is modified to perform dual functions: it now also carries and positions label transfer members. This multi-functionality eliminates the need for separate label application equipment, resolving the contradiction between achieving label application capability and maintaining apparatus simplicity.
Solution Approach 2:
The label transfer member is integrated with the tyre loader mechanism, combining two previously separate operations (label application and tyre loading) into a single coordinated action. This merging reduces device complexity by eliminating redundant mechanical systems while maintaining the label application function.
2Manufacturing precision
If additional mechanical devices are added for label application, then label positioning precision improves, but cycle time increases
Solution Approach 1:
Labels are pre-positioned on the label transfer member before the tyre loading operation. The tyre loader, with its precise positioning capabilities already optimized for tyre placement, then transfers these pre-positioned labels to the tyre sidewall. This preliminary action leverages existing precision mechanisms rather than adding new ones, maintaining cycle time while achieving accurate label positioning.
Solution Approach 2:
The label transfer member acts as an intermediary carrier that bridges the label application process and the tyre loading process. By using this intermediate element, the system achieves precise label positioning through the tyre loader's established positioning accuracy without requiring separate precision positioning mechanisms for label application.
3Manufacturing precision
If specialized operators and mechanical devices are used for label placement, then label application quality improves, but safety risks increase
Solution Approach 1:
The tyre loader system performs label application automatically as part of its standard loading sequence, eliminating the need for specialized operators to manually place labels in hazardous zones. The system serves itself by integrating label transfer functionality into the automated loading process, improving quality through consistency while removing safety risks associated with human intervention.

AI summary
An apparatus for vulcanising and moulding tyres comprises a vulcanisation mould (100), a tyre loader (21) configured for loading a green tyre (2) to be moulded and vulcanised in the vulcanisation mould (100) and a label transfer member (31). The label transfer member (31) comprises: a support portion (35), configured for retaining a label (26) to be arranged in the vulcanisation mould (100), and a grip portion integral with the support portion (35). The tyre loader (21) is also configured for clasping the grip portion and moving the label transfer member (31) between a position spaced from the vulcanisation mould (100) and a position of engagement with the vulcanisation mould (100). In the engagement position, the label transfer member (31) is configured in order to release the label (26) in the vulcanisation mould (100) before the vulcanisation mould (100) receives the green tyre (2) to be moulded and vulcanised.
