Warehouse Handling Robot With Telescopic Picking on a Reference Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling robots in intelligent warehousing systems are inefficient in transporting ordered inventory items due to many containers being stored, with some containing no ordered articles, leading to low efficiency.
Innovation Solution
A handling robot with a movable chassis, material handling device, and manipulator that includes a temporary storage unit, telescopic arm, and lifting assembly, allowing precise positioning and retrieval of inventory items using a preset horizontal reference line and vertical movement to optimize storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the robot transports entire racks with multiple containers, then the robot can carry more inventory items, but the efficiency of transporting ordered articles decreases because many containers do not contain ordered articles
Solution Approach 1:
The patent divides the rack into multiple independent containers, each capable of being individually accessed and manipulated. The manipulator can selectively interact with specific containers rather than moving the entire rack, enabling precise retrieval of ordered articles from only the necessary containers while leaving others stationary.
Solution Approach 2:
The patent extracts the manipulator as a separate functional component that can independently access and remove specific containers from the rack. This allows the system to take out only the containers containing ordered articles for transport, rather than moving the entire rack structure with all its containers.
2Adaptability or versatility
If the manipulator uses both pushing and pulling surfaces, then the manipulator can handle inventory items more flexibly, but the device complexity increases
Solution Approach 1:
The manipulator is designed with dual-function surfaces that can both push and pull inventory items. The same manipulator structure performs multiple operations (pushing items onto the rack, pulling items from the rack, and transporting them), eliminating the need for separate mechanisms for each function and reducing overall system complexity.
Solution Approach 2:
The manipulator uses a pulling surface that can also function as a pushing surface by reversing its action. Instead of requiring completely separate pushing and pulling mechanisms, the same surface structure achieves opposite functions by changing the direction of force application, simplifying the device design.

AI summary
A method for retrieving an inventory item based on a handling robot, where the handling robot includes: a storage frame; and a material handling device installed on the storage frame, and including a telescopic arm and a manipulator installed to the telescopic arm; and the method for retrieving an inventory item includes: driving, by the telescopic arm, the manipulator to extend to a preset position of warehouse shelf along a preset horizontal reference line; loading, by the manipulator that is remained on the reference line, the inventory item located in the preset position; driving, by the telescopic arm, the manipulator loaded with the inventory item to move to the storage frame along the reference line; and unloading, by the manipulator that is remained on the reference line, the inventory item to the storage frame.
