Tire Forming Drum Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of forming drums and support elements in carcass structure building lines for vehicle tires is complex, leading to longer building times, increased resource usage, and larger plant sizes, especially when using semifinished products stored in advance.
Innovation Solution
A method where forming drums and support elements are managed independently, with different association and dissociation modalities, allowing for efficient movement and elimination of temporary storage and specialized transfer devices, reducing the size of the building line and optimizing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forming drums and support elements are managed together with unified association and dissociation procedures, then the building process maintains operational simplicity, but the building time increases and productivity decreases
Solution Approach 1:
The patent applies segmentation by dividing the management of support elements into independent segments. Each support element (first and second) is managed separately with independent association and dissociation procedures. The first support element is associated/dissociated at a first workstation while the second support element is associated/dissociated at a second workstation, allowing parallel processing and reducing overall building time without requiring complex unified management systems.
Solution Approach 2:
The patent implements dynamics by making the association and dissociation procedures adaptable and flexible. The forming drum can be associated with support elements at different workstations depending on the operational phase, and support elements can be independently associated or dissociated based on specific building requirements. This dynamic management approach optimizes building time while maintaining operational simplicity.
2Reliability
If specialized transfer devices and temporary storages are used for managing support elements, then the reliability of support element management is improved, but the plant size increases and resource usage increases
Solution Approach 1:
The patent extracts and eliminates the need for specialized transfer devices and temporary storage systems. By implementing independent association and dissociation procedures at different workstations, the system directly transfers support elements between stations without requiring intermediate storage areas or complex transfer mechanisms, thereby reducing plant size while maintaining management reliability.
Solution Approach 2:
The system enables self-service by allowing each workstation to independently manage its own association and dissociation operations. The first workstation handles the first support element while the second workstation handles the second support element, with each station performing its functions autonomously without requiring external transfer devices or temporary storage, thus reducing resource usage and plant footprint.
3Ease of operation
If forming drums are moved between workstations with support elements still associated, then the ease of operation is improved, but the loss of time occurs during unnecessary association/dissociation cycles
Solution Approach 1:
The patent applies preliminary action by performing the association and dissociation operations at appropriate workstations before the forming drum is moved to the next stage. The first support element is associated/dissociated at the first workstation, and the second support element is associated/dissociated at the second workstation, ensuring that all necessary support element operations are completed before the forming drum proceeds, thereby eliminating unnecessary association/dissociation cycles and time losses.

AI summary
Method, process and plant for building tires for vehicle wheels wherein: in a service position of a carcass structure building line, a forming drum is associated with a pair of support elements including a first support element and a second support element; the forming drum is moved, associated with the pair of support elements, in a deposition line in the carcass structure building line; and the forming drum is transferred from the deposition line to a subsequent work station of the carcass structure building line. The transfer from the deposition line to the subsequent work station includes dissociating the forming drum from the second support element, keeping the forming drum associated with the first support element; transferring the forming drum, associated with the first support element and dissociated from the second support element, to the subsequent work station; dissociating, in the subsequent work station, the first support element from the forming drum, leaving the forming drum in the subsequent work station; and transferring the first support element, dissociated from the forming drum, into the service position.
