Air Conditioner Coil
Handling
Condenser & Evaporator Lifting for Assembly
Cynergy Ergonomics Case Study
REQUIREMENT:
Due to a change in EPA Efficiency Requirements, industrial
HVAC equipment manufacturers have been required to increase
the efficiency of their units which has led to an increase
in the weight and size of the condenser and evaporator coils
used in the systems. After being assembled, the 12’ long x
4’ wide coils, weighing 100 lbs. need to be lifted off of
transportation carts, rotated and set on forming tables.
Once formed, the coils need to again be lifted then set in
the bottom pans. When handling the coils, accommodations
need to be made for the fact that they are extremely
flexible in the pre-formed configuration and susceptible to
damage during the handling process.
SOLUTION:
Several devices were provided to handle the coils throughout
the assorted manufacturing phases. These include
semi-automated units designed to raise, rotate and deliver
the coils to the braze line utilizing the upper cap, keying
off of the variances in upper caps in order to identify the
specific coil being handled and automatically adjusting
machine settings for the individual sizes. The system
receives coils in an upright configuration, manipulates the
coil to the required orientation, drops the coil into the
transportation pit and presents it to the braze line robotic
arm ready for end cap installation. Down stream, handling
systems which utilize mechanical grippers pick, raise and
rotate the coils as required through the forming and final
assembly process. These systems utilize pneumatic powered
manipulators suspended from workstation-style overhead
suspension systems.
RELATED APPLICATIONS:
Material handling for coils, automatic coil handling
equipment, condensate drain for air handling unit cooling
coil, coil lifters, heavy coil handling, narrow aisle coil
lifter, coil handling equipment.
