3. INTRODUCTION
The aim of production engineer is to increase the output
particularly in mass production . This technique of transfer
device has been introduce to achieve same motive .
The transfer devices are often the most suitable method for
continuous flow of identical or view similar component in the
mass production of consumer goods.
4. NEED OF TRANSFER DEVICES
High product demand
Better assembly process for mass production
Less time required for production
5. TRANSFER SYSTEM
These are special purpose system where the component are
transferred automatically from one machining head to another
machining head.
For example CNC rotary transfer machine.
Types of transfer system
Continuous transfer system
Synchronous transfer system
Asynchronous transfer system
Stationary transfer system
6. TRANSFER MECHANISM
Transfer mechanism are used to move the work
piece from one station to another station in the
machine or from one machine to another –to enable
various operations to be performed on the part.
For examples
rails
Rotary indexing tables
Overhead conveyors
7. TYPES OF TRANSFER MECHANISM
Liner transfer mechanism
Walking beam mechanism
Powered rollers
Chain drive conveyor system
Rotary transfer mechanism
Rack and pinion
Ratchet and pawl
Geneva mechanism
13. TYPES OF TRANSFER DEVICES
Inline transfer devices
The in-line configuration assembly system consists of
a sequence of workstations in a more-or-less straight-
line arrangement .
The in-line assembly machine consists of a series of
automatic workstations located along an in-line
transfer system. It is the automated version of the
manual assembly line.
Continuous, synchronous, or asynchronous transfer
systems can be used with the in-line configuration.
14. ROTARY INDEXING TABLE TRANSFER DEVICE
the base part are indexed around a circular table or
dial.
The workstations are stationary and usually located
around the outside periphery of the dial.
The parts ride on the rotating table and arc
registered or positioned, in turn, at each station a
new component is added to base part.
16. TRANSFER DEVICES USED IN TRANSFER
MACHINE
Roller conveyor
Wheel conveyor
Chute conveyor
Belt conveyor
Chain conveyor
Magnetic belt conveyor
Bucket conveyor
17. FEEDERS
A feeder is the means by which the rate of solid
flow from a hopper or bin is controlled .
Feeder feed material to conveyors, processors and
other equipment at a controlled rate to maximize
the efficiency and production.
Feeders differ from conveyors in that the latter are
only capable of transporting material not modulating
the rate of flow.
Dischargers are also not feeder
