Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conveyor systems for transporting sand molds from mold forming machines to metal pouring stations lack efficiency and flexibility, particularly in automating the feeding process from multiple origins to a common destination.
Innovation Solution
The implementation of a walking beam-type mold conveyor system that includes multiple transfer conveyors with movable central rails and junction resting stations, allowing sand molds to be transferred between conveyors and oriented in different directions to efficiently feed multiple sand mold forming machines to a single metal pouring station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linear conveyor system is used to transport sand molds, then the structure is simple, but the system cannot accommodate multiple forming machines feeding a single pouring station
Solution Approach 1:
The conveyor system is divided into multiple independent walking beam conveyors, each capable of receiving molds from different forming machines. Each conveyor segment can operate independently, allowing flexible configuration to accommodate multiple origins while maintaining manageable complexity through modular design.
Solution Approach 2:
The system transitions from a single linear conveyor path to a multi-dimensional arrangement where multiple conveyors operate in parallel and can merge at junction points. This dimensional expansion allows molds from multiple forming machines to be directed to a single pouring station through spatial organization rather than complex sequential control.
2Adaptability or versatility
If sand molds are transferred between conveyors at junction stations, then flexibility to accommodate multiple machines is improved, but transfer time and potential downtime increase
Solution Approach 1:
The walking beam conveyors are designed to operate continuously with overlapping cycles. While one conveyor is transferring molds at a junction station, other conveyors continue transporting molds without interruption. The synchronized operation ensures that mold flow remains continuous throughout the system, minimizing idle time and maintaining constant productive action.
3Adaptability or versatility
If multiple transfer conveyors with movable rails are used, then the ability to orient molds in different directions is improved, but the device complexity and maintenance requirements increase
Solution Approach 1:
The central rails are designed to be movable rather than fixed, allowing them to shift position to accommodate molds oriented in different directions. This dynamic capability enables the system to adapt to various forming machine configurations and mold orientations without requiring complete system reconfiguration, balancing versatility with manageable complexity through controlled mobility.
