Component Supply Device With Pallet Storage for Fewer Setup Exchanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply devices require frequent operator intervention for pallet replenishment and collection, especially in multi-type and small-quantity production scenarios, leading to increased labor and time burdens.
Innovation Solution
A component supply device with a magazine unit, pallet pulling-out mechanism, storage, and replacement mechanism that allows for the storage of a larger number of pallets, reducing the need for frequent setup replacement work by enabling simultaneous exchange of multiple pallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a magazine holding multiple pallets is used, then the number of setup replacement works is reduced, but the magazine occupies significant space and requires frequent exchanges in multi-type production
Solution Approach 1:
The system is divided into multiple independent magazines (first magazine and second magazine) that can operate independently. This segmentation allows the component supply device to switch between different magazines based on production needs, reducing the frequency of exchanges while maintaining flexibility for multi-type production.
Solution Approach 2:
Multiple magazines are combined within a single component supply device, allowing simultaneous storage of different pallet types. The device can switch between magazines without requiring complete replacement, thereby reducing exchange frequency while supporting diverse production requirements.
2Ease of operation
If a magazine holding multiple pallets is used, then operator workload is reduced, but the device requires large space for magazine storage and exchange
Solution Approach 1:
The storage capacity is segmented across multiple compact magazines rather than requiring one large magazine. This approach maintains adequate pallet storage while reducing the overall space footprint of the device.
Solution Approach 2:
Multiple magazines are arranged in a nested or stacked configuration within the component supply device, maximizing space utilization. This allows multiple magazines to occupy minimal additional space while maintaining accessibility for selective use.
3Adaptability or versatility
If magazines are exchanged frequently to respond to multi-type production, then production flexibility is improved, but the burden on the operator increases
Solution Approach 1:
The system uses multiple specialized magazines that can be pre-configured for different component types. This allows rapid switching between production types by simply changing which magazine is active, rather than requiring frequent exchanges during operation.
Solution Approach 2:
Multiple magazines are prepared in advance with different pallet configurations suitable for various production types. This preliminary preparation enables quick switching between production types without requiring operators to perform frequent exchange operations during production.

AI summary
Provided is a component supply device that further reduces the burden on an operator as compared with the conventional art. The component supply device includes: a magazine unit provided with a magazine accommodating multiple pallets each of which holds multiple components; a pallet pulling-out mechanism configured to selectively pull out the pallet from the magazine and transfer the pallet to a component supply position of a component mounter; a storage configured to store a larger number of the multiple pallets than the magazine unit; and a replacement mechanism configured to replace the pallet between the magazine and the storage.
