Tire Building Plant Forming Drum Transfer Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire manufacturing processes and plants face inefficiencies due to varying cycle times across work stations, limiting overall productivity and flexibility, especially when using different semifinished products with distinct materials and sizes.
Innovation Solution
Implementing a method that involves the use of multiple forming drums and intermediate transfer locations to optimize the loading and unloading process, allowing for reduced cycle times without compromising production quality or flexibility, by utilizing an auxiliary handling device to manage the transfer of forming drums between work stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sequential transfer methods are used between work stations, then device complexity is reduced, but productivity decreases due to longer cycle times
Solution Approach 1:
The incoming forming drum is loaded onto the intermediate handling device in advance, before the outgoing drum has completely exited the work station. This preliminary positioning allows for overlapping operations where the next drum is ready to be transferred immediately after the current drum completes its cycle, reducing idle time and increasing productivity
Solution Approach 2:
An intermediate handling device is introduced as a mediator between the entry and exit locations of the work station. This intermediary component temporarily holds forming drums and coordinates their transfer timing, enabling smoother workflow and reduced cycle times without requiring complete redesign of the entire production line
2Loss of time
If multiple forming drums are managed with simple sequential handling, then device complexity is minimized, but loss of time increases due to longer drum replacement intervals
Solution Approach 1:
The auxiliary handling device pre-positions the incoming forming drum at the exit location before the outgoing drum is fully removed. This advance preparation eliminates waiting time during drum replacement operations, as the next drum is already in position and ready for immediate engagement with the work station
Solution Approach 2:
The system maintains continuous useful action by ensuring that while one forming drum is being processed, the next drum is being prepared and positioned simultaneously. The auxiliary handling device enables overlapping of operations, preventing idle time and maintaining continuous production flow
3Productivity
If production line is optimized for high productivity, then manufacturing speed increases, but adaptability decreases when producing different tyre sizes and materials
Solution Approach 1:
The handling system is designed with dynamic, adjustable components that can adapt to different forming drum sizes and weights. The auxiliary handling device can be reconfigured for different production requirements, allowing the line to maintain high productivity while accommodating various tyre specifications through flexible positioning and transfer mechanisms

AI summary
A plant for building tyres includes a plurality of working locations, at least one first working location being associated with at least two loading/unloading locations, a proximal one and a distal one, each of said working locations and loading/unloading locations being associable with a forming drum. The production cycle is controlled by the method of: (i) loading a first forming drum into the at least one first working location; (ii) loading a second forming drum into the loading/unloading location; (iii) at the end of the working provided in the at least one first working location, unloading the first forming drum into the proximal loading/unloading location.
