Automated Material Transfer & AS/RS:
•Introduction
“The movement, storage, protection and control of materials throughout the
manufacturing and distribution process including their consumption and disposal”
(The Material Handling Industry of America)
•Handling of materials must be performed
Safely
Efficiently
At low cost
In a timely manner
Accurately (the right materials in the right quantities to the right locations, position
and orientation)
And without damage to the materials
ENT471 Automation
, Automated Material Transfer & AS/RS:
Design Considerations in Material Handling
Material characteristics
Flow rate, routing, and scheduling
Plant layout
Unit load principle
Flow rate - amount of material moved per unit time (pieces/hr, pallet loads/hr)
Whether the material must be moved in individual units, as batches, or continuously
Routing - pick-up and drop-off locations, move distances, routing variations, conditions along
the route
Scheduling - timing of each delivery. Prompt delivery when required. Use of buffer stocks to
mitigate against late deliveries
Material characteristics :
Solid, liquid or gas
Size, Weight, Shape - long, flat, bulky
Condition - hot, cold, wet, dirty
Risk of damage - fragile, brittle, sturdy
Safety risk - explosive, flammable, toxic, corrosive

Plan Layout
Material handling equipment considerations must be included in the plant layout
design problem
Correlation between layout type and material handling equipment:
Plant layout type Material handling equipment
Process Hand trucks, forklift trucks, AGVS
Product Conveyors for product flow
Unit Load
The unit load should be as large as practical for the material handling system that
will move and store it.
A unit load is the mass that is to be moved or otherwise handled at one time
Reasons for using unit loads in material handling:
•Multiple items handled simultaneously
•Required number of trips is reduced
•Loading/unloading times are reduced
•Product damage is decreased

Material Transfer System
There many type of material transfer system. Common material transfer usually
using following system.
• Conveyor system
• Rotary Index table
• X-Y table
• Automated Guided Vehicle (AGV)
• Pick and Place Robot
Material transfer system play very important role to move part or component from
magazine to process station (load and unload) or from machine to another
machine to perform manufacturing process.
