Friction Roller Can Rotation Eliminates Gear Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional can necking machines require frequent gear changes due to debris accumulation, leading to time-consuming and costly maintenance, as gears can fracture during the lubrication process.
Innovation Solution
A waxer assembly that utilizes frictional forces between a drive roller and a rotating housing, eliminating the need for gear engagement by using a rubber O-ring and replaceable drive rollers to rotate the can bodies, thereby reducing maintenance costs and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gear engagement is used to rotate can bodies, then reliable rotation is achieved, but debris accumulation causes gear fracture and frequent maintenance
Solution Approach 1:
The patent replaces the gear engagement mechanical system with a friction-based mechanical system. The drive roller contacts the can body through friction rather than gear teeth engagement, eliminating the problem of debris accumulation between gear teeth. This substitution maintains reliable rotation while eliminating the need for frequent gear replacement and maintenance.
Solution Approach 2:
The patent employs replaceable drive rollers that can be easily swapped when worn, replacing expensive and complex gear assemblies. The simple friction-based roller design allows for quick replacement without requiring operator disassembly of complex mechanisms, significantly reducing maintenance time and costs.
2Ease of operation
If gear teeth are used to rotate can bodies, then effective rotation is achieved, but operator intervention is required for gear changes
Solution Approach 1:
The friction-based drive roller system eliminates the need for complex gear engagement mechanisms, allowing for simpler operation and quicker maintenance. When drive rollers need replacement, operators can quickly swap them without the time-consuming process of disassembling and reassembling gear systems.
3Productivity
If can rollers with gears are used, then can body rotation is achieved, but debris lodged between gear teeth causes fracture
Solution Approach 1:
The patent substitutes the gear engagement system with a friction-based system where the drive roller contacts the can body surface. This eliminates the crevices and interlocking surfaces where debris can accumulate, preventing the harmful effect of debris-induced fracture and enabling continuous operation without interruptions for gear maintenance.

Function Achieved in This Case
The frictional-based rotation system reduces maintenance needs by allowing easy replacement of O-rings and drive rollers, enhancing operational efficiency and reducing downtime in the can necking process.
Implementation Method 1
friction between the drive roller and the peripheral surface of the housing causes the roller assembly to rotate

AI summary
An apparatus for rotating a container body that utilizes frictional forces rather than the engagement of gears to rotate the container body is provided. Such an apparatus may include a stationary housing and a turret rotating on a shaft proximate to the housing. The turret may have a plurality of pockets and a roller assembly disposed within each pocket. Each roller assembly may have a body portion and a drive roller portion. Each body portion may have a contact portion for contacting a container body received in a respective pocket. Each drive roller may be in contact with the housing such that as the turret rotates, friction between the drive rollers and the housing causes each roller assembly to rotate.
