Transfer Robot Lifting Mechanism for High Cargo Box Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional inventory container-to-person sorting methods require robots to move entire containers, increasing their load and resource waste, and make it difficult for personnel to access upper cargo boxes.
Innovation Solution
A transfer robot with a movable chassis, door frame, temporary storage mechanism, and cargo box conveying mechanism, featuring a self-driven lifting mechanism that separates the lifting mechanism from the temporary storage, allowing vertical movement independent of the storage height, facilitating access to higher inventory containers and reducing the robot's operational load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot moves the entire inventory container to the picking area, then the cargo boxes can be accessed by personnel, but the robot's load increases and resources are wasted
Solution Approach 1:
The system divides the inventory container into individual cargo boxes. Instead of moving the entire container, the robot selectively picks and places individual cargo boxes between the inventory container and temporary storage spaces, reducing the robot's load while maintaining access capability
Solution Approach 2:
A temporary storage mechanism with multiple temporary storage spaces is introduced as an intermediary between the inventory container and the picking area. Cargo boxes are first transferred to temporary storage spaces, then personnel can access them without the robot needing to move the entire container
2Adaptability or versatility
If the temporary storage mechanism is integrated with the robot structure, then the system is compact, but the lifting height is limited by the storage mechanism position
Solution Approach 1:
The lifting mechanism is separated from the temporary storage mechanism. The lifting mechanism is connected to the door frame and can move the cargo box conveying mechanism independently between different heights, while the temporary storage mechanism remains fixed on the door frame, enabling greater lifting height range
Solution Approach 2:
The lifting mechanism is designed as a self-driven dynamic system that can adjust the height of the cargo box conveying mechanism according to the position of target cargo boxes in the inventory container, allowing the system to adapt to different storage heights and improve versatility
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
Enhances the robot's versatility and efficiency by enabling it to handle higher inventory containers while simplifying personnel access to cargo boxes, reducing resource waste and improving transfer efficiency.
Implementation Method 1
the lifting drive unit drives the lifting transmission assembly to transmissively cooperate with the auxiliary transmission member (23), so that the lifting mechanism is vertically raised and lowered along the auxiliary transmission member (23)

AI summary
A transfer robot comprises a movable chassis, a door frame vertically arranged on the movable chassis, and a temporary storage mechanism and a cargo box conveying mechanism which are arranged on the door frame, wherein the temporary storage mechanism is provided with a plurality of temporary storage spaces used for temporarily storing cargo boxes, and the cargo box conveying mechanism can stretch horizontally and lift vertically relative to the door frame so as to convey the cargo boxes between the temporary storage space and a temporary inventory container.
