Carousel Drive Synchronization in Glass Hollow Article Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press-blow molding machines for producing hollow glass bodies face issues with complex drive systems requiring precise synchronization, leading to mechanical play, wear, and maintenance challenges, which affect production efficiency and safety.
Innovation Solution
The implementation of decentralized servo drives for both feed and takeout devices, along with a carousel equipped with direct drives and robots, eliminates mechanical play and wear, enabling precise control and reducing maintenance needs through predictive maintenance and contactless energy transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex drive system with multiple hierarchies and gear wheel pairings is used to achieve precise synchronization, then the gob can be transferred precisely into the preform, but mechanical play and wear occur, requiring permanent adjustment during operation
Solution Approach 1:
The patent replaces the complex mechanical drive system with multiple hierarchies and gear wheel pairings with a simplified direct drive system. The main drive (100) is directly connected to the takeout (101) without intermediate differential gears or cam discs, eliminating mechanical play and wear while maintaining precise synchronization through direct mechanical coupling.
Solution Approach 2:
The patent extracts and removes the unnecessary intermediate components (differential gears, cam discs, multiple hierarchies) from the drive system. By taking out these complex elements, the system achieves precise gob transfer without the mechanical play and wear that necessitated permanent adjustments in the prior art.
2Manufacturing precision
If a complex drive system with multiple hierarchies is used, then synchronization can be achieved, but the arrangement becomes highly complicated and requires highly complicated precision
Solution Approach 1:
The patent substitutes the complex hierarchical mechanical drive system with a simplified direct drive architecture. The main drive (100) directly actuates the takeout (101) through a single drive shaft, eliminating the need for multiple differential gears, cam discs, and adjustment mechanisms while maintaining precise synchronization.
Solution Approach 2:
Instead of using multiple intermediate stages to achieve synchronization, the patent inverts the approach by using a single direct connection. The synchronization is achieved not through complex multi-stage gearing but through the direct mechanical coupling of the main drive to the takeout mechanism.
3Ease of operation
If mechanical rotary transmitters are used to transmit media, then water, vacuum, cooling air, compressed air or lubricating oil can be transmitted, but the transmitters are subject to wear and are very difficult to access for maintenance
Solution Approach 1:
The patent replaces mechanical rotary transmitters with magnetic coupling technology. The magnetic coupling allows transmission of rotational motion and media without physical contact between rotating and stationary parts, eliminating wear and enabling easy maintenance by simply removing the external magnet rather than dismantling complex mechanical assemblies.
