Cap Box Frame Joining via Revolver Pocket Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process for cap box cigarette packs is inefficient, particularly in connecting the base part and frame, which hinders the production of a sufficient number of packs in a unit of time.
Innovation Solution
A method and device that synchronously coordinate multiple production lines to connect the base part and frame using a connecting turret with pressure elements, ensuring precise gluing of the frame sections to the base side walls within a pocket system, allowing for simultaneous production of multiple packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a continuously rotating press tool with a punch is used to join the base and frame, then the joining process can be automated, but the production efficiency is insufficient to produce a sufficient number of packages per unit of time
Solution Approach 1:
The device is divided into multiple independent production lines (at least three), each with its own receptacle for joining base and frame components. This segmentation allows parallel processing of multiple packages simultaneously, dramatically increasing production efficiency while keeping each individual production line relatively simple in structure.
Solution Approach 2:
Multiple production lines are merged into a single integrated device with coordinated and synchronized operation. The receptacles are arranged in a circle and rotate together, with all production lines sharing common control and coordination mechanisms, thereby achieving high productivity through parallel processing while maintaining manageable device complexity.
2Productivity
If multiple production lines are coordinated and synchronized to produce multiple cap boxes simultaneously, then productivity increases, but the coordination and synchronization requirements increase device complexity
Solution Approach 1:
The receptacles are designed with universal functionality to perform multiple operations: holding the frame and base, providing lateral support during joining, and facilitating the gluing process. This multi-functionality reduces the need for additional specialized components, thereby increasing productivity without proportionally increasing device complexity.
Solution Approach 2:
The frame is pre-positioned in the receptacle before the base is joined to it. The receptacle provides preliminary lateral support to the erected base side walls, ensuring proper alignment and positioning before the actual joining operation occurs. This preliminary action simplifies the coordination required during the joining process.
3Strength
If pressure elements are used to press the frame against the base side walls for gluing, then connection strength improves, but the complexity of the pressing mechanism increases
Solution Approach 1:
The receptacle itself provides the pressing function through its structure. The walls of the receptacle laterally support the erected base side walls and the frame, creating the necessary pressure for gluing without requiring separate complex pressing mechanisms. The receptacle essentially serves dual purposes: holding components and providing pressing force.
Solution Approach 2:
The receptacle is designed as a multi-functional component that simultaneously holds the frame and base, provides lateral support during erection, and applies pressing force during gluing. This universality achieves strong connections while avoiding the need for additional specialized pressing mechanisms.

AI summary
A method for manufacturing cigarette packs of the cap-box type, comprising a base (10) and a circumferential frame (17) arranged within the base (10), which abuts the base and side walls (13, 14). The latter is provided with glue or a glue strip on its outer surface. The bond is formed in pockets (39) of a revolver (25) by pressure pieces (44, 45) which transfer pressure to the inside of the frame (17) and press it against the base and side walls (13, 14) of the base (10).
