Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current can seaming equipment is either too large and costly for small batch production or requires extensive training and is expensive to operate, lacking a cost-effective and efficient solution for forming double seam can seals.
Innovation Solution
A can seaming apparatus comprising a frame, can handling assembly, driving assembly, and seaming assembly, with a lower and upper chuck configuration that allows for manual operation, featuring overcenter mechanisms and adjustable rollers to form a double seam can seal efficiently and inexpensively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large automated can seaming equipment is used, then productivity and sealing quality are improved, but device size and cost increase
Solution Approach 1:
The can seaming apparatus is divided into separate functional modules: a can holding assembly with upper and lower chucks, a seam forming assembly with rollers, and a driving mechanism. This segmentation allows each component to be optimized independently while maintaining overall functionality, enabling compact design without sacrificing sealing capability.
Solution Approach 2:
The apparatus employs movable rollers in the seam forming assembly that can be adjusted and positioned dynamically during operation. The rollers move sequentially to form different stages of the double seam, allowing a compact device to perform multiple sealing operations that would otherwise require large fixed equipment.
2Ease of operation
If manual operation is used, then ease of operation and cost are improved, but productivity decreases
Solution Approach 1:
The can holding assembly incorporates an overcenter locking mechanism that automatically secures the can between upper and lower chucks when the can is inserted. The driving mechanism automatically rotates the chucks to position the can for sealing, and the seam forming rollers automatically apply the double seam. This self-service automation maintains ease of operation while significantly improving productivity over purely manual methods.
Solution Approach 2:
The apparatus pre-positions the can using the overcenter locking mechanism and pre-orients it through automatic rotation before the sealing operation begins. This preliminary positioning ensures the can is correctly aligned for sealing, allowing rapid sequential operation without manual adjustment between cans, thereby improving productivity while maintaining simplicity.
3Manufacturing precision
If extensive training is required, then operational precision is improved, but ease of operation worsens
Solution Approach 1:
The seam forming assembly incorporates adjustable rollers with fixed positioning mechanisms that provide consistent sealing pressure and alignment. The overcenter locking mechanism provides tactile feedback when the can is properly secured, and the automatic rotation system ensures correct orientation. These feedback mechanisms ensure high seam quality without requiring operators to learn complex adjustment procedures.

AI summary
A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers which can selectively be directed to engage the can to form the necessary crimping operations.
