Tray Delivery Optimization via Simultaneous Crane Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tray delivery logic in secondary battery production increases working time and production costs due to the inefficient transfer of single trays, rather than simultaneous delivery of trays of the same type, which limits efficiency and time reduction.
Innovation Solution
A method and system for optimizing tray delivery by controlling a crane to load and transfer trays in a priority order, allowing simultaneous delivery of trays within a defined delivery stand-by limit time, thereby enhancing temporal and spatial efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate logic on the delivery operation is used to transfer trays one by one, then the system is simple to control, but the working time is increased and production efficiency is reduced
Solution Approach 1:
The patent merges multiple tray delivery operations into a single batch transfer. The crane loads multiple trays onto the conveyor belt simultaneously and transfers them together in one operation, rather than transferring trays individually. This combining of operations directly reduces the number of transfer cycles and eliminates waiting time between sequential transfers, thereby improving productivity and reducing total working time.
Solution Approach 2:
The system performs preliminary actions by pre-loading multiple trays onto the conveyor belt before the transfer operation begins. The control unit identifies multiple delivery-required trays in advance, loads them onto the belt in the correct sequence, and positions them for simultaneous transfer. This preliminary preparation enables the crane to execute a single efficient transfer operation rather than multiple sequential operations.
2Loss of time
If multiple trays are loaded onto the conveyor belt and transferred simultaneously, then the delivery time is reduced, but the control complexity increases
Solution Approach 1:
The control unit incorporates feedback mechanisms to manage the complexity of simultaneous tray loading and transfer. It monitors the positions of multiple trays on the conveyor belt, tracks which trays have been loaded, and adjusts the loading sequence based on delivery requirements. The system receives feedback from sensors detecting tray positions and uses this information to coordinate the crane's loading and transfer operations, ensuring accurate simultaneous delivery without collision or error.
Solution Approach 2:
The system dynamically adjusts the loading and transfer process based on real-time conditions. The control unit can modify the sequence of loading trays onto the conveyor belt, adjust transfer timing, and adapt to varying tray types or delivery priorities. This dynamic control enables flexible management of multiple trays being loaded and transferred simultaneously, reducing control complexity by allowing the system to optimize operations based on current state rather than following rigid predetermined sequences.

AI summary
The present invention relates to a method of optimizing delivery of trays and a system using the method. The method includes: (a) determining a list of delivery of trays; (b) loading a delivery-required tray in the delivery list on the crane in accordance with a loading priority order; (c) loading, on the crane, another tray that can be simultaneously delivered along with the tray that has been loaded on the crane at (b), if requirement for delivery of the tray that can be simultaneously delivered is within a delivery stand-by limit time; and (d) transferring the trays loaded on the crane at (b) or (c).
