Automated Production Lines
Sections:
1. Fundamentals of Automated Production Lines
2. Applications of Automated Production Lines
3. Analysis of Transfer Lines
4. Part transfer mechanism & their applications
Automated Production Lines
High production of parts requiring multiple processing operations
dispersed workstations+work transport system Applications:
Transfer lines used for machining Robotic spot welding lines in automotive final
assembly Sheet metal press-working Electroplating of metals
Where to Use Automated Production Lines
High product demand Requires large production quantities
Stable product design Difficult to change the sequence and content of
processing operations once the line is built Long product life
At least several years Multiple operations required on product
The different operations are assigned to different workstations in the line
System Configurations
In-line - straight line arrangement of workstations Segmented in-line – two or more straight line segments,
usually perpendicular to each other Rotary indexing machine (e.g., dial indexing machine)
In-line Configurations
Common for machining big work pieces, such as automotive engine blocks, engine heads, and transmission cases
Segmented In-Line Configurations
L-shaped layout
U-shaped layout
Rectangular configuration
Rotary Indexing Machine/table
Commonly limitedto smaller workparts and relatively few workstations. . However they require
less floor space, and are generally less expensive than other configurations.

Benefits of Automated Production Lines
Low direct labor content Low product cost High production rates Production lead time and work-in-process are minimized Factory floor space is minimized
Limitations• Very low flexibility • Risk of obsolescence: due to new product
introduction • High vulnerability to failures: a failure in a
single machine blocks the whole system in very short time
Workpart Transfer Mechanisms
Workpart Transfer Mechanisms
Linear transfer systems: Belt-Driven Linear Transfer System Walking Beam Transfer System
Rotary indexing mechanisms: Geneva mechanism Others
Belt-Driven Linear Transfer System

Walking Beam Transfer System
Geneva Mechanism with four Slots
If the driven wheel has n slots,it advances by 360 degree /n per full rotation of drive wheel

mechanisms
1) Motion picture projectors
Figure shows the schematic of movie projector with Geneva mechanism. The film does not run continuously through the projector. It is requited that the film should
advance frame by frame and stands still in front of the lens for fraction of a second. Modern film projectors use an electronically controlled indexing mechanism which
allows the fast-forwarding of the film.
