Component Reel Storage Cabinet With Prepositioned Unloading Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component storing member storage cabinets require longer unloading times due to the distance of storage sections from the inlet and outlet, especially for components needed early in production.
Innovation Solution
The storage cabinet includes unloading waiting sections closer to the unloading sections, where components to be unloaded early are moved before an instruction is received, and subsequent processes move these components closer to the unloading sections or to other waiting sections based on priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If component storing members are stored in storage sections far from the inlet and outlet section, then the storage cabinet can accommodate more components, but the time required to transfer and unload them increases
Solution Approach 1:
The storage cabinet is divided into multiple storage sections with different distances from the inlet/outlet section. Storage sections are segmented into distant storage (for bulk storage) and nearby storage (for frequent access), allowing the system to optimize between storage capacity and unloading speed by placing different types of components in appropriately located sections.
Solution Approach 2:
The control section proactively transfers component storing members from distant storage sections to nearby storage sections before they are actually requested for unloading. This preliminary action anticipates future unloading needs and positions components in optimal locations in advance, reducing actual unloading time when components are needed.
2Productivity
If component storing members are stored in sections far from the inlet and outlet, then storage density increases, but the distance for transfer increases unloading time
Solution Approach 1:
The control section performs preliminary transfers of component storing members from distant storage sections to nearby storage sections based on predicted usage patterns and unloading requests. This advance positioning ensures that high-priority components are already in proximity to the inlet/outlet when needed, maintaining high transfer speeds without sacrificing storage efficiency.
Solution Approach 2:
The system dynamically adjusts the distribution of components across different storage sections based on real-time and historical unloading patterns. Frequently accessed components are automatically positioned in nearby storage sections, while less frequently accessed components remain in distant sections, optimizing the balance between storage efficiency and transfer speed.
3Loss of time
If all component storing members are kept in nearby storage sections, then unloading time is reduced, but storage capacity is reduced
Solution Approach 1:
The storage cabinet is segmented into multiple functional zones: distant storage sections for bulk inventory, nearby storage sections for active components, and intermediate buffer zones. This segmentation allows the system to maintain large total storage capacity while ensuring that only the necessary subset of components is positioned for rapid access, optimizing the trade-off between capacity and speed.
Solution Approach 2:
The control section anticipates unloading requests and proactively transfers component storing members from distant to nearby storage sections before they are actually needed. This preliminary positioning reduces actual unloading time without requiring all components to be permanently stationed in nearby sections, thereby preserving overall storage capacity.

AI summary
A parts tower that stores reels storing components to be mounted on substrates includes storing sections storing the reels, loading and unloading sections in which the reels are disposed, a moving section that moves the reels inside the parts tower, an operation section receiving an instruction of unloading of the reels, and a controller. Some of the storing sections that are disposed around the loading and unloading sections are defined as unloading waiting sections. The controller performs a first moving process in which the reels that are to be unloaded relatively early among the stored reels to the unloading waiting sections are moved by the moving section before receiving the instruction of unloading the reels, and a second moving process in which the reels stored in the unloading waiting sections are moved to the loading and unloading sections by the moving section in response to receiving the instruction.
