Cigarette Casing Feed Mechanism for Continuous Auto-Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal cigarette-making machines require manual positioning of cigarette casings and can only produce one cigarette at a time, posing difficulties for users with dexterity or vision impairments.
Innovation Solution
A cigarette filling apparatus with a casing hopper, dispensing chute, and oscillating member, coupled with sensors and motors, automatically positions casings and dispenses tobacco, allowing for continuous production without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual positioning of casing is required, then device complexity is reduced, but productivity decreases and ease of operation worsens for users with dexterity or vision impairments
Solution Approach 1:
The system performs preliminary actions by automatically positioning the casing on the outlet before the filling operation begins. The positioning mechanism includes a movable outlet that can be adjusted to receive the casing, and a sensor detects when the casing is properly positioned. This preliminary positioning action eliminates the need for manual intervention during the filling process, thereby increasing productivity while maintaining acceptable device complexity through automated detection and positioning systems.
2Productivity
If one cigarette is made at a time with manual positioning, then device complexity remains low, but productivity is limited and time consumption increases
Solution Approach 1:
The system enables continuous production by maintaining the outlet in a ready state and automatically positioning casings for filling without interruption. The sensor continuously monitors the outlet to detect when a casing is properly positioned, and the filling mechanism can immediately proceed without waiting for manual intervention. This continuous operation allows multiple cigarettes to be produced in sequence, increasing batch production capability while minimizing time loss between operations.
3Ease of operation
If automated positioning is implemented, then ease of operation improves for users with dexterity or vision impairments, but device complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting when a casing is properly positioned on the outlet using a sensor, and initiating the filling operation without requiring user intervention. The outlet is designed with specific geometric features that guide the casing into the correct position, and the sensor provides feedback to the control system to confirm proper positioning. This self-service capability significantly improves ease of operation for users with dexterity or vision impairments while keeping device complexity manageable through straightforward sensing and control mechanisms.
