Solution Overview

Problem

Existing apparatuses for forming collations of rod-shaped articles, such as cigarettes, are limited in their ability to efficiently utilize space on production lines and in facilities, and they often require complex mechanisms and high energy consumption, while also restricting the arrangement of different types of articles within a collation.

Innovation Solution

An apparatus featuring a hopper and lateral feeder that allows for the efficient arrangement of first and second rod-shaped articles into pockets on a conveyor belt, utilizing gravity-fed feeding paths and optional pneumatic or mechanical assistance to position articles orthogonally, reducing the need for moving parts and energy consumption, and enabling the arrangement of multiple types of articles in a single collation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a lateral feeder is positioned remotely from the hopper in a direction orthogonal to the conveyance direction, then space utilization on the production line is improved, but the feeding path length increases which may affect gravity feeding efficiency

Engineering Contradiction:
Improvespace utilization on production lineVSAvoidfeeding path length
Core Design Contradiction:
Area of stationary objectVSLength of moving object

Solution Approach 1:

The lateral feeder is positioned in a direction orthogonal to the conveyance direction, utilizing the lateral dimension rather than extending along the production line. This dimensional change allows space optimization without significantly increasing the effective feeding path length, as the feeder operates in a different spatial plane.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple types of rod-shaped articles are arranged in a single collation with complex positioning, then product versatility is improved, but the device complexity increases

Engineering Contradiction:
Improvearrangement of different types of articlesVSAvoidapparatus structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hopper is divided into multiple compartments, with each compartment dedicated to storing a specific type of rod-shaped article. This segmentation allows different article types to be fed simultaneously into a single collation without requiring complex mixing or sorting mechanisms, thereby achieving versatility while maintaining relatively simple device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The single hopper structure serves multiple functions by incorporating multiple compartments that can handle different types of rod-shaped articles. This multi-functional design eliminates the need for separate feeding systems for each article type, reducing overall device complexity while maintaining the ability to create diverse collations.

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

3Manufacturing precision

If traditional feeders with moving parts are used for precise article positioning, then manufacturing precision is improved, but maintenance costs and device complexity increase

Engineering Contradiction:
Improvearticle positioning precisionVSAvoidnumber of moving parts
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system utilizes the natural gravity and physical properties of the rod-shaped articles themselves to achieve precise positioning. Articles automatically orient and position themselves as they move through the hopper compartments and onto the conveyor, eliminating the need for complex mechanical positioning devices with moving parts.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Complex mechanical positioning systems with multiple moving parts are replaced by a gravity-based passive positioning system. The hopper compartment design and article geometry work together to automatically position articles correctly without requiring actuators, motors, or other active mechanical components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
