Multi-Apparatus Shelf Retrieval Layout for High-Rack Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo-to-person systems face stability issues due to high vertical frames, while shuttle vehicle rack systems occupy excessive space and incur high costs, making them unsuitable for high shelves.
Innovation Solution
A cargo storing and retrieval system with multiple cargo retrieval and placing apparatuses that move along transverse rails, allowing for efficient retrieval and placement across multiple layers with reduced vertical height and space occupancy, utilizing a temporary storage assembly for improved efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a cargo-to-person system with a high vertical frame is used to meet high shelf requirements, then the system can access higher storage layers, but the operation stability of the fork mechanism deteriorates
Solution Approach 1:
The system divides the high shelf into multiple storage units, each served by a dedicated cargo retrieval and placing apparatus. Each apparatus operates within a limited vertical range rather than spanning the entire shelf height, which maintains operational stability while enabling access to all storage layers through coordinated segmentation of the retrieval task across multiple apparatuses.
2Length of stationary object
If a shuttle vehicle rack system with lifting layer-changing mechanism is used to meet high shelf requirements, then the system can access higher storage layers, but the space occupancy and cost increase
Solution Approach 1:
The cargo retrieval and placing apparatus moves along the surface of the shelf in horizontal directions (front-to-back and left-to-right) rather than using vertical lifting mechanisms. This dimensional shift allows the system to access high storage layers by traversing horizontally to the appropriate storage unit, eliminating the need for complex vertical lifting infrastructure and reducing overall space occupancy.

AI summary
Disclosed is a cargo storing and retrieval system. The cargo storing and retrieval system includes a shelf (1) and a plurality of cargo retrieval and placing apparatus (2). The shelf (1) has a storage unit. The storage unit includes a plurality of rows of storage spaces (12) disposed in a vertical direction. Each row of storage spaces (12) includes a plurality of storage positions (121) disposed side by side. The storage unit is provided with at least two cargo retrieval and placing apparatuses (2). A cargo retrieval and placing apparatus (2) is a main cargo retrieval and placing apparatus (2a) corresponding to a main retrieval and placing region. All two main retrieval and placing regions are disposed sequentially from top to bottom and jointly cover all the storage spaces (12) of the storage unit. Two adjacent main retrieval and placing regions overlap to cover at least one row of storage spaces (12) to form a first common retrieval and placing region (122). The main cargo retrieval and placing apparatus (2a) is able to move along a surface of the shelf (1) to retrieve and place a cargo (5) that is at a storage position (121) and is in a main retrieval and placing region corresponding to the main cargo retrieval and placing apparatus (2a).
