Solution Overview

Problem

Capping machines face challenges in adapting to varying bottle sizes due to the inflexibility of the guide corridor, particularly the vertical gravity chute, which affects the efficient feeding of metal caps.

Innovation Solution

The guide corridor is designed to be adjustable in length and height, featuring a telescopic section with a baffle that forms a Z or bayonet shape, allowing the angle of the oblique portions to be 45°, and a cradle-like structure with sliding systems to accommodate different bottle sizes, ensuring continuous guidance without snagging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a long fixed guide passage is used to feed capping articles, then the feeding function is stable, but the machine cannot adapt to varying bottle sizes

Engineering Contradiction:
Improveadaptation to varying bottle sizesVSAvoidcomplexity of adjustable guide corridor
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide corridor is transformed from a fixed structure to a dynamic, adjustable one. The lower section can be displaced vertically relative to the upper section, allowing the guide passage to adapt its configuration to different bottle sizes while maintaining feeding functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide corridor is divided into two distinct sections: an upper fixed section and a lower adjustable section. This segmentation allows independent movement of the lower section to adapt to different bottle heights while the upper section remains stationary, resolving the contradiction between adaptability and structural simplicity

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the capping head is vertically displaced to match different bottle sizes, then the adaptability improves, but the guide corridor dimension must be manually adjusted

Engineering Contradiction:
Improvevertical displacement managementVSAvoidmanual adjustment requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The guide corridor's lower section automatically adjusts its position relative to the upper section through the vertical displacement of the capping head. The system self-adapts to different bottle sizes without requiring manual intervention to adjust the guide corridor dimensions, improving ease of operation while maintaining adaptability

Inventive Principle:
Principle #25Self-service

3Productivity

If the guide corridor length is reduced for small bottles, then the feeding efficiency improves, but the structure becomes inflexible for large bottles

Engineering Contradiction:
Improvefeeding efficiencyVSAvoidflexibility for different bottle sizes
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The guide corridor's lower section can dynamically adjust its vertical position to optimize the passage length for different bottle sizes. For small bottles, the section moves closer to reduce passage length and improve feeding efficiency; for large bottles, it moves farther to maintain adequate clearance, thus resolving the contradiction between productivity and adaptability

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a guide track associated with a capping machine, comprising a capping head (4) that is adjustable to fit the different formats of bottles (1). Said track comprises, upstream from and adjacemt to the capping head (4), a telescopic portion (9) consisting of a section (16) rigidly connected to said capping head (4) and movable with the latter, and a stationary section (15) rigidly connected to a general frame (2). The telescopic portion (9) of the guide track (6) for caps (5) comprises side walls (19-22), the surface of which is smooth, i.e. continuous and uniform, regardless of the position of the stationary section (15) and the movable section (16) in relation to one another. The stationary section (15) and the movable section (16) are transversely shifted, and guided with regard to one another, by means of a runner system (32).
