Cigarette Package Erecting and Insertion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of Shell and Slide type cigarette packs is hindered by complex folding turret designs, resulting in low production speeds, which applies to both Shell and Slide packs and other packs with outer and inner components.
Innovation Solution
The method involves transporting the outer packaging blank with longitudinal sides transverse to the transport direction, using a coupled erecting and counter-erecting element, and employing a conveyor belt to feed the inner pack into the outer pack, with insertion aids to facilitate the insertion process, allowing for higher production speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a folding turret design is used for producing Shell and Slide packs, then the packaging structure can be formed, but the production speed is limited due to complex design
Solution Approach 1:
The invention divides the packaging process into separate functional modules: a magazine for supplying outer pack blanks, a separate erection mechanism with erecting elements, and an insertion mechanism for inner packs. This segmentation eliminates the need for a complex folding turret while maintaining packaging formation capability and enabling higher production speeds through parallel operations.
Solution Approach 2:
Outer pack blanks are pre-positioned in the magazine in a ready-to-erection state before the actual packaging operation. The erecting elements are pre-configured to receive and erect blanks as they are supplied, eliminating the need for complex on-the-fly folding operations and enabling continuous high-speed production.
2Manufacturing precision
If traditional gripping and erecting methods are used, then the outer pack blank can be formed, but the alignment precision with the inner pack is insufficient
Solution Approach 1:
The invention introduces insertion elements as intermediaries between the erected outer pack and the inner pack. These insertion elements guide and position the inner pack during insertion, ensuring precise alignment without requiring complex adjustment mechanisms in the erection device itself.
Solution Approach 2:
The erecting elements are designed to create a standardized erection position for outer pack blanks, establishing a reference level that ensures consistent alignment with subsequently inserted inner packs. This equipotential approach simplifies the erection mechanism while maintaining high precision through repeated positioning.

AI summary
The method involves removing a blank for an outer package from a magazine (34), and pushing an inner package i.e. slider, into the outer package. The outer package is held in an area of a transport path after the alignment for accommodating the inner package. The outer package is arranged in the transport path such that longitudinal sides of the outer package are aligned parallel to the transport path. The inner package is moved in a relative position along the transport path and inserted into the outer package, where the outer package is designed as a casing. An independent claim is also included for a device for manufacturing a cigarette package.
