Tire Manufacturing Device Adjacent Stitcher Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in tire manufacturing arises from the time-consuming process of molding the inner liner layer, which delays the transfer of the carcass band to the next process, causing inefficiencies in the production line.
Innovation Solution
The tire manufacturing device and method incorporate a design where the stitcher position and transfer position are adjacent, allowing the carcass band to be immediately transferred after molding, eliminating the need for it to pass through the first moving portion and thereby reducing waiting time for the completion of the inner liner layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the molding drum completes the inner liner layer molding before transferring the carcass band, then the inner liner layer quality is ensured, but the production efficiency deteriorates due to waiting time
Solution Approach 1:
The patent applies preliminary action by positioning the stitcher device and transfer device adjacent to each other, allowing the stitcher to complete the carcass band formation and immediately transfer it to the transfer device without waiting for the molding drum to complete a full rotation for inner liner layer molding. This preliminary arrangement of adjacent positions enables the carcass band to be transferred as soon as stitching is complete, eliminating unnecessary waiting time while maintaining quality standards.
2Ease of manufacture
If the stitcher position is located at the end of the second moving portion, then the molding process is simplified, but the transfer efficiency deteriorates due to the distance from the transfer position
Solution Approach 1:
The patent applies dimensionality change by repositioning the transfer position from the traditional end-of-molding-location to an adjacent position near the stitcher device. This spatial reconfiguration in the dimensional arrangement allows the carcass band to be transferred immediately after stitching without requiring the molding drum to rotate through a long distance, thus improving transfer efficiency while keeping the molding process simple.
3Stability of the object's composition
If the carcass band waits for inner liner layer completion before transfer, then the molding sequence is maintained, but the overall manufacturing time increases
Solution Approach 1:
The patent applies preliminary action by arranging the stitcher device and transfer device adjacent to each other, enabling the transfer operation to be prepared and executed immediately after stitching completion. This preliminary positioning allows the system to bypass the waiting period that would otherwise be required for the molding drum to complete the inner liner layer molding cycle, thus reducing manufacturing time while maintaining proper molding sequence through controlled operation timing.

AI summary
A tire manufacturing device includes: a molding drum; a first moving portion in which the molding drum moves in order to mold an inner liner layer on the molding drum; a second moving portion in which the molding drum moves in order to mold a ply layer on the inner liner layer; a stitcher position where a carcass band is formed by performing pressing from above the ply layer laminated on the inner liner layer; and a transfer position where the carcass band is transferred from the molding drum to a transport device that transports the carcass band to a subsequent process, and the stitcher position and the transfer position are adjacent to each other.
