Solution Overview

Problem

Existing packaging lines for smoking articles require layout changes to switch between producing different packet types, leading to complexity and inefficiency.

Innovation Solution

A machine that maintains the same layout to produce packets of two different types using interchangeable wrapping units and a conveying system with a feeding device, ensuring seamless transition between packet types without structural changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the packaging line is equipped with mutually interchangeable operating units to switch between different packet types, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveability to produce different packet typesVSAvoidlayout variation requirement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single packaging line layout that can handle multiple packet types through a unified conveying system. The conveying system is designed to accommodate both individual packets and groups of packets, allowing the same physical infrastructure to perform multiple functions without requiring layout changes or interchangeable operating units.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the packaging line uses interchangeable operating units to switch between packet types, then the versatility is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvepacket type switching capabilityVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The conveying system is designed with universal handling capabilities that can process both individual packets and groups of packets through the same operational流程. The system includes a unified inlet for receiving packets, a conveying mechanism that can accommodate different packet configurations, and a single outlet for dispensing finished products, eliminating the need for operational changes when switching packet types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A machine (1) for producing packets of smoking articles of two different types, comprising: - a first wrapping unit (10) for wrapping ordered groups of cigarettes in an inner wrapper, which makes semifinished packets of a first type (110); - a second wrapping unit (20) for wrapping ordered group of cigarettes in a hermetically closed inner wrapper, which makes semifinished packets of a second type (120), the semifinished packets of the second type having one or more sealing or fixing areas, or points, which stably maintain closed the semifinished packets; - a packaging unit (30) for forming a closed outer casing around the semifinished packets of the first or second type, starting from a blank of sheet material; - at least one conveying device (40) for transferring the semifinished packets of the first or second type to the packaging unit (30); and - a feeding device (50) which is connected to the second wrapping unit (20) for receiving the semifinished packets of the second type (120) from the second wrapping unit, and which is configured to feed - one after another - the semifinished packets to the conveying device (40).
