Quick-Coupling Ejector Part for Fast Can End Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closure application devices require significant time and effort for adjustments when processing different types of containers or can ends, leading to high downtime and assembly effort due to the need for replacing and re-adjusting ejector parts.
Innovation Solution
A device with a detachable ejector part attached via a quick-coupling mechanism, allowing for easy replacement and adjustment of the ejector part's position using shims, enabling quick conversion between container types without mechanical machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ejector part is attached to the ejector unit with a nut and requires individual readjustment, then the device can process different types of containers, but the assembly effort and downtime increase significantly
Solution Approach 1:
The ejector part is segmented as a separate, detachable component from the ejector unit. This allows the ejector part to be quickly removed and replaced without affecting the ejector unit itself, enabling rapid changeover between different container types without time-consuming assembly operations.
Solution Approach 2:
The system transitions from a static, permanently attached ejector part to a dynamic, interchangeable configuration. The detachable connection allows the ejector part to be easily repositioned and replaced, providing adaptability for different container types while minimizing setup time through simple attachment/detachment operations.
2Productivity
If the ejector part is detachably attached via quick-coupling mechanism, then the replacement time is reduced, but the device complexity increases
Solution Approach 1:
The coupling mechanism is extracted as a standardized, pre-engineered component that provides quick-connect functionality. This allows the ejector part to be detachably attached to the ejector unit through a simple, tool-free operation, significantly reducing replacement time while the standardized design keeps the added complexity manageable.
Solution Approach 2:
The quick-coupling mechanism is designed as a universal interface that can accommodate different ejector parts for various container types. This multi-functional coupling system enables rapid replacement and interchangeability, improving productivity while the standardized design prevents excessive complexity multiplication.
3Adaptability or versatility
If individual readjustment of each closer device is required, then the processing can be adapted to new container types, but the assembly effort increases
Solution Approach 1:
The ejector part is segmented as a modular component that can be independently replaced on each closer device. This modular approach allows individual customization for different container types while reducing assembly effort, as the pre-manufactured ejector parts require only simple attachment rather than complex adjustment procedures.

AI summary
The present invention relates to a device (1) for applying a container closure to a container, for example for applying a can end to a can, for example in a beverage filling plant, comprising an application unit (10) with a closure receptacle (11) for receiving a container closure, and an ejector unit (20) movable relative to the application unit (10) for ejecting a container closure received in the closure receptacle (11). An ejector part (21), for example in the form of an ejector shield, is arranged on the ejector unit (20) on its side facing the closure receptacle (11) and comes into physical contact with the container closure for ejecting the container closure. The ejector part (21) is detachably attached to the ejector unit (20) via a quick-coupling mechanism (30). It further relates to a closer (100) comprising the device (1).
