Longitudinal Strip Applicator for Cigarette Web Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of cylindrical smokers' articles is hindered by the high costs and complexity of manufacturing machines due to the need for specialized rolls of web material with pre-applied annular inserts, which require intricate synchronizing systems for proper positioning.
Innovation Solution
An apparatus that applies longitudinal strips of web material with adhesive to a continuous sheet, allowing for the creation of annular inserts during the wrapping process, enabling flexible positioning and material choice, and separate applicator devices for independent control of strip placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specialized rolls of web material with pre-applied annular inserts are used, then the positioning of annular inserts is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the web material into two separate components: the base web and the annular inserts. Instead of having pre-applied inserts on specialized web rolls, the inserts are applied separately to the web material during the cigarette making process. This segmentation eliminates the need for complex synchronizing systems while maintaining proper positioning of inserts.
Solution Approach 2:
The annular inserts are applied to the web material in advance of the wrapping operation, but through a simple application process rather than pre-positioned specialized rolls. The inserts are applied to the web surface beforehand, and then the web with inserts is wrapped around the cigarette components, achieving proper positioning without complex synchronization.
2Manufacturing precision
If specialized rolls of web material with pre-applied annular inserts are used, then the positioning of annular inserts is improved, but the manufacturing cost increases
Solution Approach 1:
By separating the web material and annular inserts into distinct components, the patent eliminates the need for expensive specialized web rolls with pre-applied inserts. The inserts can be manufactured separately and applied to standard web material, significantly reducing manufacturing costs while maintaining positioning accuracy.
Solution Approach 2:
The patent uses simple, inexpensive annular inserts that can be applied to the web material rather than requiring expensive specialized web rolls. This approach replaces costly reusable specialized rolls with cheaper individual inserts that are applied as needed.
3Ease of manufacture
If standard web material is used without pre-applied inserts, then the manufacturing cost decreases, but the ability to provide annular inserts deteriorates
Solution Approach 1:
The annular inserts are applied to the web material in advance of the wrapping operation through a simple application mechanism. This preliminary application allows standard web material to be transformed into functional web with inserts, maintaining low manufacturing costs while providing the necessary adaptability for different insert configurations.
Solution Approach 2:
The system allows dynamic adjustment of insert application based on production requirements. Different types of annular inserts can be applied to the web material as needed, providing versatility while maintaining the simplicity and low cost of using standard web material as the base.
