Movable Tray for Order-Picking Stability and Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing order-picking systems face challenges in ensuring the safe and efficient transportation of loads on trays, as existing trays do not adequately prevent loads from slipping or falling off due to vibrations during transportation.
Innovation Solution
The tray design features two side walls that project upwards from the transport base and the loading base, allowing for automated relative movement between the upper and lower parts of the tray, enabling automatic unloading and providing increased stability and rigidity to the loading base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the loading base is fixed in a lower position on the transport base, then the load is stable during transportation, but the load cannot be easily unloaded from the tray
Solution Approach 1:
The loading base is designed to be movable relative to the transport base, transitioning between a lower transport position (providing stability) and an upper transferring position (enabling easy unloading). This dynamic repositioning allows the system to optimize for either stability or ease of operation depending on the operational phase.
2Ease of manufacture
If the tray structure is simplified for easy manufacturing, then production cost is reduced, but the tray cannot provide sufficient stability and rigidity to prevent load slipping during vibration
Solution Approach 1:
The tray is divided into separate components: a transport base and a loading base that can move relative to each other. This segmentation allows each component to be optimized independently - the transport base provides structural stability and vibration resistance, while the loading base enables easy load placement and removal, maintaining both manufacturing simplicity and load security.
3Productivity
If the loading base is positioned higher to enable push-off unloading, then unloading efficiency is improved, but the load may become unstable during transportation
Solution Approach 1:
The loading base dynamically adjusts its position - located higher when unloading is needed to enable efficient push-off, and lower during transportation to maintain load stability. This dynamic positioning resolves the contradiction between unloading efficiency and transport stability.

AI summary
A multi-part tray for transporting a load in an order-picking system includes four side walls, a lower part and an upper part movable relative to the lower part from a transport configuration into a transferring configuration. The lower part provides two first side walls and the upper part provides two second side walls. Furthermore, with an unloading device and a method for unloading the tray, the upper part is moved relative to the lower part in order to move the tray from the transport configuration into the transferring configuration. Further, a computer-implemented method controls a position changing device in order to bring a load into a loading pose for loading a tray. In addition, a loading device carries out the method. Finally, an order-picking system has trays, an unloading device and/or a loading device.
