TRANSFER MECHANISMS

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%),
