Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter rod making machines in the tobacco industry face challenges in accurately placing beads or objects with flavor substances due to inefficient air discharge, leading to variable fiber distribution and improper object positioning, especially at higher speeds, resulting in production waste.
Innovation Solution
A member for guiding filter fibers with a slot and vent holes that stabilize the fiber strand by discharging excess air, ensuring accurate and repeatable placement of objects by maintaining a guiding channel from the inlet to the outlet opening, with vent holes arranged radially or perpendicular to the slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the speed of filter fiber delivery is increased to improve productivity, then the manufacturing speed increases, but the accuracy of bead placement decreases due to insufficient air discharge
Solution Approach 1:
The invention extracts and removes excess air from the fiber strand through specifically designed vent holes in the guide member. By creating dedicated air discharge pathways, the system separates the air removal function from the fiber guiding function, enabling efficient air extraction that maintains placement accuracy even at high manufacturing speeds.
Solution Approach 2:
The guide member acts as an intermediary component between the fiber strand and the bead placement mechanism. It provides a controlled environment with integrated vent holes that mediate the interaction between moving fibers and placed beads, ensuring stable fiber positioning and accurate bead placement simultaneously.
2Reliability
If air discharge efficiency is improved to maintain fiber stability at high speeds, then placement repeatability increases, but the device complexity increases due to additional vent hole structures
Solution Approach 1:
The invention merges the air discharge function with the fiber guiding function by integrating vent holes directly into the guide member structure. This combination eliminates the need for separate air removal devices, reducing overall system complexity while improving placement repeatability through efficient air management.
Solution Approach 2:
The guide member is designed with porous characteristics through the inclusion of multiple vent holes, allowing air to pass through the structure. This porous design enables effective air removal from the fiber strand without requiring complex mechanical air extraction systems, maintaining simplicity while improving reliability.
