TRANSFER MECHANISMS
SHARATH C M
BENGALURU
Why transfer mechanism?
• The goal of a production engineer is to increase the o/p particularly in mass production.
• Transfer devices are often the most used/suitable method for continuous flow of identical or similar components in mass production.
General configuration of an automated production line consisting of n automated workstations that perform processing operations
L-shaped layout
U-shaped layout
Rectangular configuration
Linear transfer systems:• Continuous motion – not common for automated systems
• Synchronous motion – intermittent motion, all parts move simultaneously
• Asynchronous motion – intermittent motion, parts move independently
Rotary indexing mechanisms:• Geneva mechanism
• Others
Study shows how an environmental disturbance, acts as one of vital source factor in
production.
In this paper an effort is made to study the various amounts of change in production
considering factors like environment, temperature variations, employee working
circle, etc...
The study was pertaining to semi-conductor industry, where a slightly little facing time
towards environment of a product could cause the upper protection layer/coating
could go degrade over certain ratios.
So, study concluded with a result that transfer of product data to the least employee
could decrease such degradation of products...
Knowledge transfer and competitive advantage on environmental uncertainty:
An empirical study of the Taiwan semiconductor industry
Shu-Hsien Liao, Ta-Chien Hu
As causal ambiguity increases, the positive relationship between the
perception of a source’s trustworthiness and the level of accuracy of the
reproduction of the template will first weaken and then, under conditions of
high causal ambiguity, turn negative.
This article also considers that environmental uncertainty is an important
variable that has an effect on knowledge transfer and can hinder an
organization from acquiring sustained competitive advantage

In the below shown fig. pivoting causes the first link to pivot about itsproximal end and causes the end effector to pivot in the two link version andcauses the second and third links to pivot about their pivot axis in the threelink version.
Precision arm mechanismInventors: Genco Genov, Lubomir Skrobak, et. All.
Claims: 32 new modifications.
Example: An arm structure, design compression, etc.…
This invention provides parts of arm structure, which are useful for movingdelicate materials from on position to another in any direction forprocessing, loading, unloading. This can give “0” & “Z” movements quiteeasily.
The use of inner liner rods make it flexible & capable of modification of itswork volume, degree of precision, etc.…
What is the foremost benefit of automation?What types of problems are linked to automation? What tasks are either not suitable to automate or to conduct manually?
THE INDUSTRY’S VIEW ON AUTOMATION IN MANUFACTURING Lindstrom, Winroth, et. All.
Division of Production Systems, Chalmers University of Technology & IME Sweden.
Relation between human and technology in terms of task and function
allocation, which can be expressed as an index between 1 (total manual
work) and 9 (total automation) of physical as cognitive tasks.
The focus is on the participants background, experience, and expertise.
Both from the preliminary study as well as the Delphi study it could be concluded
that work in hazardous environments or monotonous and physically demanding
working situations are not suitable to be conducted manually.
Conclusion:
Automation will give cost savings
within production (100%),
give possibilities for higher efficiency
(98%),
increased competitiveness (97%),
productivity (94%).
Automation will also give possibilities
to improve working environment
(93%),
