HOT ROLL BLANKS LUBRICANT
ROLLER COATER Series 45 - Model A
An extremely rugged, heavy-duty roller coater for applying lubricant
to heavy gauge hot roll blanks.
SYNONYMS
Depending on your industry, you may call this a hot roll blank lubricator,
a roller coater, a roll coater, heavy-duty coater, or a heavy-duty roller
coater.
ROLL CONFIGURATION
In the Model A Double Coater Roll Configuration, the liquid coating is held in the troughs between the coating rolls and their companion doctor rolls, top and bottom.
OPERATIONAL DESCRIPTION
The Union Series #45, Model A, Special Roller Coater was built for
a special application. This coater applies a lubricant to heavy gauge
hot roll blanks, changing an energy wasting hot form operation into
a cold form operation using very little energy and requiring no additional
labor.
The lubricant is premixed in tanks and then pumped to the two independent
coating heads. Level controls operate valves that automatically maintain
the level of lubricant in the crotches of the coating heads without
damage or overflow.
A custom drive shaft on this coater drives a short infeed conveyor
section and a roll-type offbearing conveyor section. As the blanks move
down an existing conveyor driven by the coater, they enter the nip of
the coating rolls. This nip is controlled automatically by air cylinders
with screw mechanical stops. As the blank is being coated, it is transported
on the offbearing roller-type conveyor up against a backstop.The backstop
automatically signals the conveyor to reverse, and the coating rolls
to pop open. This moves the sheet back through the coater onto the short
infeed conveyor section, where it is then stopped and moved by chains
at a 90-degree angle into the press.
The variable DC drive, the automatic pop-open coating heads, the recirculating
system and offbearing conveyor are but a few of the options available
on Union Tool roller coating equipment.
We pride ourselves on the ability to build heavy-duty roller coating
equipment to meet individual applications, maximizing efficiency, reducing
costs and saving labor. Submit your requirements to the Union Tool Corporation-we'll
offer our ideas and cost estimate for equipment designed to meet your
individual needs.
