Shelf Transport Vehicle Vertical Guide and Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf storage systems face challenges in quickly moving transport vehicles between levels due to the elasticity of ropes used in elevator systems, which requires complex and time-consuming control algorithms to maintain a constant position, increasing the duration of entry and exit processes.
Innovation Solution
A device and method for conveying a shelf storage transport vehicle in a vertical direction using a traction elevator system with a guide device, stop elements, and a drive device, including a hoisting rope, where the hoisting rope is de-energized after reaching a crossing position to prevent movement, allowing the transport vehicle to enter or exit without complex control measures, and a tension detection mechanism to prevent upward movement due to load reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rope elevator system is used to transport the transport vehicle between levels, then the transport vehicle can be moved vertically, but the elasticity of the ropes causes the cabin to change position when the transport vehicle enters or exits, requiring complex and time-consuming control algorithms
Solution Approach 1:
The patent extracts the problematic elastic component (the hoisting rope) from the system during the critical entry/exit operation. By detaching the rope from the cabin before the transport vehicle enters or exits, the elastic effect is completely removed from the system during this phase, eliminating position changes and the need for complex control algorithms to compensate for rope elasticity.
Solution Approach 2:
The patent performs the rope detachment action before the transport vehicle enters or exits the cabin. This preliminary action prepares the system in advance by removing the elastic element that would otherwise cause position changes during the entry/exit process, allowing for simple and quick operations without requiring complex real-time control.
2Manufacturing precision
If complex control algorithms are used to maintain constant cabin position during transport vehicle entry and exit, then position stability is improved, but the overall duration of entry and exit processes increases
Solution Approach 1:
The patent removes the hoisting rope from the system during entry/exit operations, eliminating the source of position instability. This extraction approach achieves perfect position stability (the cabin remains fixed) without requiring any control algorithms, thereby dramatically reducing the time needed for entry and exit processes.
Solution Approach 2:
By detaching the rope beforehand, the system prepares for a stable, time-efficient entry/exit operation. The preliminary detachment ensures the cabin position remains constant throughout the entire entry/exit process without requiring real-time control adjustments, optimizing both precision and speed.
3Speed
If the hoisting rope remains tensioned during transport vehicle entry and exit, then the transport element can be quickly positioned, but the elasticity of the rope causes unwanted movement when load changes occur
Solution Approach 1:
The patent completely removes the hoisting rope from the connection between the drive device and the cabin during entry/exit operations. This extraction eliminates the elastic effect that causes unwanted movement when load changes occur, ensuring reliable and stable positioning without requiring the rope to remain tensioned.
Solution Approach 2:
The rope is detached in advance before the transport vehicle enters or exits, preparing the system for stable operation. This preliminary action ensures that no elastic effects will interfere with position stability during the critical entry/exit phase, while allowing the transport element to be positioned quickly using alternative means.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables faster and more reliable movement of the transport vehicle between levels, reducing the overall duration of entry and exit processes by avoiding computationally expensive control measures and addressing the issue of rope elasticity, thus enhancing operational efficiency.
Implementation Method 1
Due to the elasticity of the ropes used, especially wire ropes, they can expand when the cabin is loaded or contract when the load is reduced.
Implementation Method 2
The device comprises at least one guide device and the at least one transport element for the transport vehicle. The movement of the transport element in and counter to the vertical direction can be guided by means of the guide device.
Implementation Method 3
The stop element can be in a stop state or can be placed in this stop state (be displaceable) or be in a release state or be placed in this release state (be displaceable). The at least one stop element of the guide device is arranged in such a way that the stop elements block a movement of the transport element counter to the vertical direction
