Transfer Robot Support Assembly for Stable High-Shelf Container Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transfer robots with multi-stage gantries used in storage systems are prone to shaking when handling high-level containers, leading to failure in handling tasks.
Innovation Solution
A transfer robot equipped with a pick-and-place assembly and an auxiliary support device that extends to abut against carriers, providing stability during container handling by synchronously adjusting its height and extending support mechanisms to stabilize the robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a transfer robot with multi-stage gantry is used to pick and place high-level containers, then the robot can reach high storage positions, but the robot shakes during handling operations
Solution Approach 1:
The patent introduces an auxiliary support device as an intermediary element between the transfer robot and the storage system. This support device provides additional stabilization during container handling operations, allowing the robot to maintain reach height while reducing shaking through external support structures that distribute mechanical loads and dampen vibrations.
2Stability of the object's composition
If the robot structure is increased to improve stability, then handling stability improves, but the robot size increases
Solution Approach 1:
Rather than enlarging the robot structure itself, the patent employs an auxiliary support device as an external intermediary that provides stability without increasing the robot's core volume. This support mechanism acts as a separate stabilization system that can be deployed only when needed during handling operations.
Solution Approach 2:
The auxiliary support device is designed to be dynamically deployable, extending or retracting based on operational requirements. This allows the system to transition between compact storage mode and expanded support mode, providing stability only when needed while maintaining a compact form factor during non-operational states.

AI summary
The transfer robot includes: a chassis assembly, a lifting device arranged on the chassis assembly, and a pick-and-place assembly arranged on the lifting device. The lifting device is configured to drive the lifting of the pick-and-place assembly. The auxiliary support device is connected to the pick-and-place assembly and includes a driving assembly, a transmission assembly, and a support assembly. The driving assembly is connected to the support assembly by the transmission assembly to drive the support assembly to extend in a first direction relative to the pick-and-place assembly until the support assembly abuts against or separates from carriers at two sides of the transfer robot. The auxiliary support device is arranged on the pick-and-place assembly and is configured to extend to a position abutting against the carriers to support the transfer robot in the process of picking up and placing a container.
