Automated Storage Rack Cleaning Using Load-Handling Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage racks become dirty after installation or use, leading to contamination of stored goods and operational malfunctions due to dirt accumulation, which is time-consuming to clean manually.
Innovation Solution
A device with dimensions resembling a load handling device, allowing automated cleaning of storage rack crossbeams and longitudinal beams using a fan, filter, rotating brushes, and a battery-powered system, activated by a storage and retrieval machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning of storage racks is performed, then cleaning can be done with simple equipment, but it is very time-consuming and requires maintenance personnel to walk on the storage racks
Solution Approach 1:
The storage and retrieval machine performs cleaning operations autonomously during its normal operational cycles. The integrated cleaning device is activated automatically when the machine enters the storage rack, eliminating the need for separate manual cleaning operations and enabling the system to service itself.
Solution Approach 2:
The cleaning function is merged with the storage and retrieval machine by integrating a cleaning device onto the machine. This combination allows the same equipment to perform both material handling and cleaning tasks, increasing productivity without proportionally increasing overall system complexity.
2Loss of time
If manual cleaning is used, then equipment cost is low, but cleaning time increases and contamination risk remains
Solution Approach 1:
The cleaning device is positioned to clean crossbeams and surfaces before goods are stored or during retrieval operations. This preliminary cleaning action prevents dirt accumulation and contamination before it occurs, rather than requiring subsequent cleaning operations.
Solution Approach 2:
Manual mechanical cleaning operations are replaced with an automated cleaning device that uses mechanical brushes or wiping elements driven by the storage and retrieval machine's movement, substituting human labor with automated mechanical action.
3Extent of automation
If cleaning device is integrated into storage rack system, then automated cleaning is achieved, but device dimensions and handling complexity increase
Solution Approach 1:
The storage and retrieval machine is given multiple functions by integrating the cleaning device onto it. The machine now performs both its primary function of storing and retrieving goods and the secondary function of cleaning the storage rack, achieving automation without adding separate dedicated cleaning equipment.
Solution Approach 2:
The storage and retrieval machine acts as an intermediary carrier that transports the cleaning device to the required locations within the storage rack. This intermediary approach allows the cleaning function to be delivered automatically without requiring direct integration into the rack structure itself.
