Design Recommendations
In general, automation
involves high initial cost of equipment as well as a knowledge of
operation and maintenance required.
A careful study with
regards to the true needs of the organization should be carried
before deciding on implementing an automated transfer line, even
at low level at automation.
If a sufficient number
of workers is available, and if the level of their skills is high
and the labor cost is justified, the need for automation is less.
In the design of large
transfer machines, the matter of the geometric arrangement of the
various production units must be considered.
The degree of precision
needed, as well as the size, rigidity, and design of the workpieces,
play a major role in deciding whether or not to use carrier pallets
or fixtures. Those pallets and fixtures contain locating holes or
points that mate with retracting pins or fingers at each work station.
The most significant
part of the design lies in designing the line itself so that it
operates efficiently as a whole. The process time at each station
must be the same, with the total nonproductive time for all other
stations minimized.
