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 efficiency and cost-effectiveness for forming double seam can seals.
Innovation Solution
A compact can seaming apparatus comprising a frame, can handling assembly, driving assembly, and seam forming assembly, allowing manual operation with a motor-driven chuck system and pivotable rollers to efficiently form double seam can seals, suitable for smaller batch production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large automated can seaming equipment is used, then sealing efficiency and quality are improved, but equipment size and cost increase making it unsuitable for small batch production
Solution Approach 1:
The can seaming apparatus is divided into separate functional modules: a can holding assembly with chuck, a cap holding assembly with chuck, and a seam forming assembly with rollers. Each module can be independently positioned and operated, allowing the system to achieve automated sealing functionality while maintaining a compact overall size suitable for small batch production.
Solution Approach 2:
The apparatus integrates multiple functions into a single compact unit: the can holding assembly secures and positions the can, the cap holding assembly secures and positions the cap, and the seam forming assembly performs the actual seaming operation. This multi-functionality eliminates the need for large separate equipment while maintaining sealing efficiency.
2Volume of moving object
If manual operation equipment is used for small batch production, then equipment size and cost are reduced, but operational complexity and training requirements increase
Solution Approach 1:
The apparatus is designed to be self-positioning through its overcenter mechanisms. When the can and cap are placed in the chucks, the overcenter linkages automatically adjust and lock the components in the correct positions for seaming. This self-service feature eliminates the need for complex manual positioning operations and reduces training requirements while maintaining a compact equipment size.
3Manufacturing precision
If automated can seaming equipment is used, then sealing quality is improved, but operational cost and complexity increase for small batch production
Solution Approach 1:
The seam forming assembly incorporates overcenter mechanisms that dynamically adjust the position of the can and cap chucks during operation. The linkages automatically lock the chucks in the precise positions needed for high-quality sealing, providing automated precision control without requiring complex electronic systems or high equipment complexity.

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 mounted to a roller frame which pivots about an axis relative to the frame. The roller frame can be pivoted so as to selectively have the two rollers sequentially engage the can to form the necessary crimping operations.
