Direct Drive Carrier Rotation for Beverage Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary machines used in the beverage industry, such as blow molding and filling machines, suffer from high noise emissions, complex and costly gear or belt transmissions, efficiency losses due to transmission friction, and limited dynamic control behavior, particularly during braking.
Innovation Solution
A direct drive system is implemented, where a drive motor is mounted on a non-rotatable carrier with a driven wheel that interacts directly with the drive wheel, eliminating intermediate gear or belt stages and using a torque motor for efficient and dynamic control, allowing for synchronous braking and reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If intermediate gear or belt stages are used to drive the carousel, then the motor can be positioned at a collision-free location, but noise emissions increase and efficiency decreases due to transmission friction
Solution Approach 1:
The patent removes the intermediate gear or belt transmission stages from the drive system, eliminating the source of noise emissions and efficiency losses while maintaining the ability to position the motor appropriately through direct coupling to the carousel
2Ease of manufacture
If intermediate gear or belt stages are used to drive the carousel, then the motor can be positioned at a collision-free location, but efficiency is reduced due to transmission friction
Solution Approach 1:
The patent eliminates intermediate transmission stages that cause energy loss through friction, achieving direct power transmission from the motor to the carousel while still allowing proper motor positioning through the direct drive configuration
3Ease of manufacture
If geared motors are used to drive the carousel, then the motor can be positioned away from the carousel, but maintenance costs increase and reliability decreases
Solution Approach 1:
The patent removes the intermediate transmission components (gears, belts) that are prone to failure and require maintenance, implementing a direct drive system that eliminates these reliability issues while maintaining flexible motor positioning
Solution Approach 2:
The direct drive system requires no intermediate transmission components that need maintenance, making the system self-sufficient and eliminating routine maintenance requirements for transmission parts
4Ease of manufacture
If geared motors with intermediate transmission stages are used, then the motor can be positioned at a collision-free location, but device complexity increases
Solution Approach 1:
The patent eliminates the complex intermediate transmission stages (gears, belts, intermediate wheels) from the drive system, implementing a simple direct drive configuration that maintains motor positioning flexibility while dramatically reducing device complexity
5Strength
If additional mechanical brakes are used for synchronous braking, then the high mass moments of inertia can be controlled, but dynamic control behavior is limited
Solution Approach 1:
The patent replaces the mechanical brake system with an electrical braking system that uses the motor's electromagnetic fields to provide synchronous braking, eliminating the need for additional mechanical brakes and significantly improving dynamic control behavior
