Slide-Open Cigarette Packing Machine Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packing machines for producing hinged-lid, slide-open packets of cigarettes have low output levels and are inflexible, making them unsuitable for high-quality, high-volume production and easy adaptation to different types of packaging.
Innovation Solution
A packing machine and method that utilize a combination of folding and gluing processes to efficiently produce slide-open packages, featuring a first packing unit for forming an inner container with a hinged lid and a second unit for forming an outer container that slides with respect to the inner container, allowing for automatic lid rotation and easy adaptation to different packaging types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If known packing machines are used to produce hinged-lid slide-open packets, then the packets can be produced with proper quality, but the output level is low and production speed is slow
Solution Approach 1:
The packing machine is divided into separate functional units: a first packing unit for forming the inner container with hinged lid, and a second packing unit for forming the outer container. This segmentation allows each unit to be optimized independently for both quality and speed, resolving the contradiction between manufacturing precision and productivity.
Solution Approach 2:
The hinged lid is pre-formed on the inner container before the outer container is applied. This preliminary action ensures the lid structure is already in place and properly configured, allowing the subsequent outer container formation to proceed quickly without compromising the precision of lid placement, thus improving both quality and output level.
2Manufacturing precision
If known packing machines are used to produce hinged-lid slide-open packets, then the packets can be produced with proper quality, but the machine is extremely slow-operating
Solution Approach 1:
The packing process is designed as a continuous operation where the first packing unit forms the inner container with hinged lid, and the second packing unit immediately forms the outer container around it. This continuous action eliminates idle time between operations, maintaining high operating speed while ensuring each step meets quality standards through dedicated functional units.
3Ease of manufacture
If known packing machines are used to produce hinged-lid slide-open packets, then the packets can be produced, but the machines are not flexible and difficult to modify for different packet types
Solution Approach 1:
The packing machine is designed with universal components and adjustable parameters that allow it to produce different types of slide-open packets (with or without hinged lids) using the same basic structure. The separate packing units can be configured for different packet styles, providing flexibility without requiring complex modifications to the overall system.
4Productivity
If high output levels are pursued in packet production, then productivity increases, but quality standard may be compromised
Solution Approach 1:
By segmenting the packing process into separate functional units (first packing unit for inner container with lid, second packing unit for outer container), each unit can be optimized for its specific task. This allows high-speed operation in each segment while maintaining quality standards through specialized design, resolving the trade-off between productivity and manufacturing precision.
