Category : Hints on designing

July29, 2011

There are following four types of Transfers that effect locations of objects as: In-feed, Transport, Loading, and Storage. Each is explained in relation to LCA. (Storage is omitted)

(1) Classification of transfer functions

A flow of material to assembled products is simplified as the following.

Function Classification	Related Mechanism	Notes
Transfer	Conveyor types: Belt type, Chain type, Roller type Cart types: Railed transfer carts, Unmanned transfer carts, Manually operated carts	General transfer mechanism Aim for flexibility and high cost vs. performance ratio by modular concepts.
Transport	Intermittent transport types: Rotary type, Linear type, Free-flow type	Work performed on conveyor, etc.
Transport	Continuous transport type: Synchronous linear type, etc.	Work cycle time is synchronized to the intermittent drive time.
Loading	Handling robot Auto-loader P&P (Pick and place) unit, etc.	Know-how required on material handling and work-piece holding devices.
