Labor Intensive Processes
Overhead monorails
at
Sharp
automatically deliver material to robotic assembly workstations.
Conveyors
deliver parts for assembly from the mini load to ergonomic workstations at
Von Duprin
.
Problem
Processes require:
High mental aptitude (e.g., following a wiring diagram).
High physical dexterity (e.g., assembling small components).
High physical exertion (e.g., lifting and/or transporting heavy loads).
Long cycle times caused by complex, multi-task operations in non-assembly-line manufacturing.
Frequent Worker injuries and their related costs.
Lost time and reduced worker productivity.
Significant non-value added handling between processes.
Low job satisfaction, high employee turnover due to monotonous tasks.
Solution
For multi-task operations, consider de-coupling complex processes into single tasks along a small assembly line.
Reduce monotonous tasks and improve worker satisfaction by:
Using robotics to handle small component assembly tasks such as pickup, insert, and set-aside operations.
Eliminating non-value-added tasks wherever possible.
Automate delivery and takeaway of material using
