Singulation Star Startup Synchronization for Gentle Container Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container handling systems face issues with the high relative velocity between the singulation star and the container transport device during startup, leading to potential damage or destruction of the first container, and require complex synchronization processes.
Innovation Solution
The container transport device and singulation star synchronize their movements during startup to achieve identical transport speeds at the exit of the singulation star and entry of the container transport device, with a common drive unit and mechanical coupling ensuring synchronized acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the container transport device and separating star are accelerated to normal transport speed before feeding the first container, then the transport speed is sufficient for normal operation, but the first container experiences high relative speed and may be damaged or destroyed
Solution Approach 1:
The container transport device and separating star are accelerated to a starting speed before the first container is fed in, creating a synchronized motion state. This preliminary acceleration ensures that when the first container is introduced, both components are already moving at a matched speed, reducing the relative speed impact on the container.
Solution Approach 2:
The system uses dynamic speed adjustment by implementing a two-stage acceleration process: first accelerating to a lower starting speed synchronized with the container feed, then accelerating to the final normal transport speed. This dynamic approach allows the system to adapt its speed profile to protect the first container while still achieving efficient operation.
2Speed
If the container transport device is accelerated to transport speed first, then the separating star accelerates together with the first container, but control and synchronization become comparatively complex
Solution Approach 1:
The patent merges the acceleration control of the container transport device and separating star into a unified control approach. Both components accelerate together from a standstill to a starting speed, maintaining synchronization inherently through their coupled motion, thereby simplifying the control architecture compared to independent acceleration control.
3Speed
If the separating star and container transport device are accelerated in a synchronized manner to normal transport speed, then the transfer speed matches, but the first container experiences high relative speed upon transfer
Solution Approach 1:
The system performs preliminary acceleration to a starting speed that is lower than the final normal transport speed. This preliminary state allows the first container to be fed in with reduced relative speed impact. Only after the container is safely transferred does the system accelerate to the full normal transport speed.
Solution Approach 2:
The patent changes the speed parameter dynamically by implementing a two-stage acceleration profile: first accelerating to a starting speed for safe container feeding, then accelerating to the normal transport speed for efficient operation. This parameter change resolves the contradiction between transfer speed synchronization and container protection.
