Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging apparatuses for smoking articles, such as cigarettes, are limited in hourly production capacity due to the gluing process being stationary during the transfer wheel, which is not allowing high hourly productivity and the gluing together of internal and external flaps.
Innovation Solution
A transfer wheel with a movable gluing device and a movable gluing device that rotates and glues the internal and external flaps together, allowing high hourly productivity and the gluing together of internal and external flaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transfer wheel is stationary during the gluing process, then the gluing operation can be performed reliably, but the hourly production capacity is limited
Solution Approach 1:
The patent applies the dynamics principle by making the transfer wheel rotatable during the gluing process. Instead of keeping the wheel stationary to perform gluing, the wheel rotates continuously while the gluing device follows the motion to deposit adhesive. This dynamic approach allows multiple packets to be processed simultaneously at different stages of the rotation cycle, dramatically increasing hourly production capacity from limited output to over 30,000 packets per hour while maintaining gluing reliability through controlled adhesive application timing.
2Device complexity
If the gluing device is stationary, then the structure is simple, but the gluing precision and adaptability are reduced
Solution Approach 1:
The gluing device is made movable with respect to the transfer wheel, capable of radial movement to adjust its position. This dynamic configuration allows the gluing device to maintain precise contact with the packet flaps throughout the rotation cycle, ensuring accurate adhesive deposition. The movable design enables the system to adapt to different packet positions and maintain gluing precision without requiring an overly complex multi-axis positioning system.
Solution Approach 2:
The patent applies parameter changes by allowing the gluing device to vary its radial position relative to the transfer wheel. The device can move closer to or farther from the wheel's peripheral surface, adjusting the gluing parameters to match the specific requirements of different packet types and gluing conditions. This parameter adjustment capability enhances manufacturing precision while keeping the overall device structure relatively simple.
3Productivity
If the transfer wheel rotates continuously, then productivity increases, but the gluing time for each packet is reduced
Solution Approach 1:
The patent implements continuity of useful action by maintaining continuous rotation of the transfer wheel throughout the entire gluing process. Instead of stopping the wheel for each gluing operation, the wheel rotates continuously and the gluing device is positioned and activated at the appropriate moment during rotation. This continuous operation eliminates idle time and waiting periods, ensuring that packets move through the system without interruption and maximizing hourly production capacity to over 30,000 packets while minimizing total gluing cycle time.
