Transfer Drum Tire Component Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire components experience shifting during transfer from one conveyor to another or from a conveyor to a drum, making direct and reliable transfer impossible due to unsupported moments and physical limitations of conveyor extension.
Innovation Solution
A method utilizing a transfer drum to pick up and place tire components by rotating and moving it to align and retain the components, ensuring controlled transfer by maintaining contact and using retaining elements like magnets and suction to prevent shifting, stretching, or compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roller conveyor is used to convey tire components, then the tire component can be transported, but the tire component experiences position shifting during transfer between conveyors or to drums
Solution Approach 1:
A transfer drum is introduced as an intermediary device between the roller conveyor and the building drum. The transfer drum receives the tire component from the conveyor, maintains continuous contact and support, and then transfers it to the building drum. This intermediary eliminates the unsupported drop transfer, preventing position shifting while maintaining transport capability.
2Manufacturing precision
If the roller conveyor is extended to reach the drum surface, then direct transfer may be achieved, but the physical extension limit prevents complete contact
Solution Approach 1:
Instead of extending the roller conveyor horizontally to reach the drum surface, the solution introduces a vertical dimension by using a rotating transfer drum. The transfer drum rotates to bring its surface into contact with the tire component at different heights, enabling complete contact and controlled transfer without requiring excessive horizontal extension of the conveyor.
3Productivity
If the tire component is dropped from the conveyor to the drum, then transfer is achieved, but the component is momentarily unsupported causing position shift
Solution Approach 1:
The transfer drum is positioned and rotated in advance to meet the tire component before it leaves the conveyor. The drum surface is already in contact with the component, providing continuous support throughout the transfer process. This preliminary positioning and contact prevention the unsupported drop that causes position shifting.

AI summary
The invention relates to a method for picking up and placing a tire components, wherein the method includes the steps of picking up a supplied first tire component with a transfer drum, rotating the transfer drum in a first direction for winding a predetermined length of the continuous length of the first tire component, rotating the transfer drum in the opposite second direction, while at the same time moving the transfer drum downstream into a cutting position, wherein a part of the predetermined length of the first tire component is unwound from the transfer drum, cutting the unwound part, thereby obtaining a cut-to-length first tire component, and rotating the transfer drum again in the first direction for winding up the unwound part of the cut-to-length first tire component up to the trailing end.
