Reciprocating Ram Mechanism With Internal Air Path for Can Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing can body makers experience high maintenance and part replacement frequencies due to external air supply systems, leading to jamming and reduced production efficiency, as well as pressure fluctuations during can release.
Innovation Solution
A reciprocating linear motion mechanism with an internal air supply path and air chamber, minimizing external connections and stabilizing air pressure by storing air temporarily within the mechanism, allowing for efficient and timely air supply to the ram shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air is supplied from external air supply sources to ram shafts via hoses, then air can be supplied to punches, but the frequency of maintenance of connection parts and replacement of parts is high
Solution Approach 1:
The air supply path is merged with the reciprocating linear motion mechanism structure itself. The housing, rotating bodies, and ram shaft joining part form an integrated air supply system, eliminating external hoses and connection parts that require frequent maintenance.
Solution Approach 2:
The air supply function is extracted from the external hose connection system and embedded directly into the mechanism's internal structure. This removes the vulnerable external connection parts while maintaining the air supply function.
2Ease of operation
If air is supplied from external air supply sources via hoses, then air can reach the punches, but the hoses are connected to ram shafts which are operating violently, causing high maintenance frequency
Solution Approach 1:
The air supply path is combined with the moving parts themselves (rotating bodies and ram shaft joining part), eliminating the need for separate external hoses that would be subjected to violent operations and require frequent replacement.
3Productivity
If air is supplied externally to ram shafts, then air can be provided to punches for can release, but production efficiency is reduced due to frequent facility outages from jams
Solution Approach 1:
The air supply system is merged with the reciprocating linear motion mechanism to ensure stable and continuous air supply to punches, preventing can jamming and facility outages, thereby maintaining high production efficiency and operational continuity.
4Ease of repair
If an internal air supply path is used within the reciprocating linear motion mechanism, then maintenance frequency is reduced, but the mechanism structure becomes more complex
Solution Approach 1:
The housing and rotating bodies of the reciprocating linear motion mechanism serve dual functions: they both transmit mechanical motion and guide air flow. This multi-functionality adds air supply capability without requiring separate dedicated air supply components.
Solution Approach 2:
The air supply path is nested within the existing mechanical structure of the reciprocating linear motion mechanism. Air channels are integrated into the housing and rotating bodies, utilizing the existing spatial configuration rather than adding external air supply components.

Function Achieved in This Case
This solution reduces maintenance and part replacement needs, minimizes jamming, and enhances production efficiency by maintaining stable air pressure for consistent can formation and release.
Implementation Method 1
an air supply path passing through the insides of the first rotating body, the second rotating body, and the ram shaft joining part. Furthermore, it is preferable that the air supply path be arranged at least inside the first rotating body and include an air chamber having air stored therein.
Implementation Method 2
a first rotating body located inside the housing (for example, in a radial direction orthogonal to the first central axis) and relatively rotatably joined to the housing (for example, around the first central axis); a second rotating body including an external gear having a second central axis as a center parallel to the first central axis and meshing with the internal gear and relatively rotatably joined to the first rotating body (for example, around the second central axis)
