Solution Overview

Problem

In non-contact processing lines for ribbon-like articles, the feed rate of the ribbon relative to the processing unit often limits production capacity, especially when small details like patterns need to be created, requiring a slower ribbon speed that can lead to tension issues and compromised product quality.

Innovation Solution

The solution involves moving both the ribbon-like article and the operating units along a loop path, with the operating units performing non-contact processing while maintaining a controlled speed difference with the ribbon, allowing for higher feed rates and reduced tension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the ribbon-like article advances at a reduced speed relative to the operating unit, then the processing quality (pattern realization) is improved, but the production capacity is reduced

Engineering Contradiction:
Improveprocessing qualityVSAvoidproduction capacity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The operating unit is made movable along a loop path instead of being stationary, allowing its speed to be dynamically adjusted relative to the ribbon feed rate. This enables the operating unit to move at a controlled speed difference with the ribbon, maintaining processing quality while enabling higher overall feed rates and production capacity.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the ribbon-like article advances at a reduced speed, then the processing precision is improved, but tension states are generated on the ribbon

Engineering Contradiction:
Improveprocessing precisionVSAvoidribbon tension stability
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

By making the operating unit movable and controlling the speed difference between the operating unit and the ribbon feed rate, the system can maintain stable ribbon tension while achieving high processing precision. The dynamic speed adjustment prevents tension buildup that would occur with reduced ribbon feed rates.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the ribbon feed rate is increased to improve productivity, then the production capacity is improved, but the processing quality deteriorates

Engineering Contradiction:
Improveproduction capacityVSAvoidprocessing quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The operating unit moves along a loop path at a controlled speed difference relative to the ribbon feed rate. This dynamic configuration allows the ribbon to advance at high feed rates for improved productivity while the operating unit maintains the relative speed conditions necessary for high processing quality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable operating unit acts as an intermediary between the high-speed ribbon transport and the precision processing requirements. By controlling the speed difference between the operating unit and the ribbon, it mediates between the conflicting requirements of high feed rate and high processing quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An apparatus for non-contact processing on a ribbon-like article includes a conveying device of the ribbon-like article including an inlet section, an outlet section and a connecting segment extending between the inlet section and the outlet section and at least two operating units configured to perform non-contacting processing on the ribbon-like article that are movable along a loop path. The conveying device is configured to advance the ribbon-like article at a feed rate along the connecting segment. The operating units are configured to displace at a first speed along a processing portion of the loop path. The speed difference between the first speed and the feed rate is lower than a predetermined value.
