Solution Overview

Problem

Cigarette manufacturing machines for home and personal use, known as roll-your-own (RYO) machines, lack the ability to automatically produce cigarettes precisely, uniformly, and efficiently without manual intervention, often resulting in damaged tubes and insufficient tobacco compaction, and fail to accommodate user preferences for tobacco quantity and environmental conditions like humidity.

Innovation Solution

A cigarette manufacturing machine with a control system, including a computer processor and sensors, that automates the tobacco compaction and cigarette formation process, ensuring precise and uniform cigarette production by monitoring tobacco levels and humidity, and integrating a carriage assembly, tube magazine, and carrot forming assembly to manage tobacco insertion and tube handling.

AI summary

In one aspect, an apparatus for manufacturing cigarettes includes a housing, a mandrel extending from the housing, and a movable member operably coupled to the housing and adapted to carry a first cigarette tube. The movable member is movable, relative to each of the housing and the mandrel, in a first direction and a second direction that is opposite the first direction. In another aspect, a method of manufacturing cigarettes includes loading a first cigarette tube on a mandrel, holding the first cigarette tube on the mandrel, and inserting a push rod and a carrot of pre-cut tobacco leaves into the first cigarette tube, the carrot of pre-cut tobacco leaves having a generally cylindrical shape. An offset distance is defined between the first cigarette tube and the mandrel after the push rod and the carrot of pre-cut tobacco leaves are inserted into the first cigarette tube.
