Solution Overview

Problem

Existing filling and plugging systems face inefficiencies due to plugging time being shorter than filling time, requiring the filling device to wait for plugging, and positioning deviations leading to unstable operation.

Innovation Solution

A high-speed filling and plugging system with a conveying device, plug delivering device, filling device, first and second plugging devices, and a rubber plug transport device, utilizing eccentric shaft assemblies and parallelogram link mechanisms to synchronize and accurately position rubber plugs for simultaneous plugging of two rows of containers, eliminating the need for the filling and plugging devices to move along the conveying device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single filling device and a single plugging device are used, then the device complexity is reduced, but the productivity decreases due to waiting time

Engineering Contradiction:
Improveproduction efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The single plugging device is segmented into two independent plugging devices (first plugging device and second plugging device) that operate simultaneously on different rows of containers. This segmentation allows parallel processing of plugging operations, eliminating the waiting time that occurred with a single plugging device and thereby increasing overall productivity without requiring complex coordination mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first plugging device and second plugging device are merged into a coordinated system that processes multiple rows of containers simultaneously. By combining multiple plugging operations into one integrated system working in parallel, the overall plugging capacity is doubled while maintaining manageable device complexity through standardized modular design.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the filling device and plugging device move along the conveying device, then the adaptability to different container positions is improved, but the manufacturing precision decreases due to positioning deviations

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidpositioning accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Instead of moving the filling and plugging devices along the conveying direction to adapt to different container positions, the invention inverts the approach by keeping these devices stationary and allowing the containers to be positioned under them through the conveying device. This inversion eliminates positioning deviations caused by movement while maintaining adaptability through controlled container positioning.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The conveying device acts as an intermediary that precisely positions containers under the stationary filling and plugging devices. By introducing this intermediate positioning mechanism, the system achieves both adaptability (containers can be positioned at different locations) and manufacturing precision (positioning is controlled by the conveying device rather than by moving the filling/plugging devices).

Inventive Principle:
Principle #24Intermediary (Mediator)
