ROLLER COATER for
STAMPING LUBRICANT and
DRAWING COMPOUND application
A roller coater for the application of drawing compound or stamping
lubricant to metal sheets prior to metal forming operations. Includes
infeed and outfeed conveyors. Coats top side, bottom side, or both in
a single pass.
SYNONYMS
Metal formers and stampers call this machine a metal blank roll coater
or roller coater, a lubrication coater, drawing compound applicator,
metal sheet lubricator, sheet coater.
ROLL CONFIGURATION
In the Model B Double Coater Roll Configuration, the liquid coating for the top surface is held in the trough between the top coating roller and its companion doctor roll; the liquid coating for the bottom surface is held in a pan in which the bottom coating roll and its companion doctor roll both run.
OPERATIONAL DESCRIPTION
The Union Series 615, Model B, 50" Roller Coater is specifically
designed to apply drawing compound and stamping lubricants to sheet
stock prior to forming operations.
By utilizing a small, roll-type infeed conveyor and a disc-type (point
contact) offbearing conveyor, the coater can be either an independent
unit or part of a production process. This unit is being utilized behind
a roll leveler, thus requiring no additional labor. With the advance
of special lubricants, this has helped to eliminate the application
of drawing compound and stamping lubricants at the press and make a
much cleaner and safer operation.
The air cylinders, which control the doctor roll adjustment, provide
automatic setup in controlling the amount of lubricant being applied
to the stock. The upper coating head, which is adjusted in a vertical
plane, is also air cylinder-controlled. An indicator gives a reading
in thousandths of the position of the upper coating roll in relationship
to the bottom coating roll, thus compensating for different gauges of
material.
A photocell and counters are incorporated to allow the user to coat
or not coat sheets as required. The photocell signals the counters,
which are preset to the number of sheets to be counted and the number
of sheets to be skipped. The upper head, through the air cylinders,
then opens and closes, moving the coating rolls in and out of contact
with the sheets being processed.
The air cylinders may be activated automatically with the start of
the coater, or manually controlled through switches. A complete recirculating
system allows the user to coat both the top and/or the bottom of the
stock as desired.
As with all Union Tool roller coating equipment, this unit was designed
and fabricated to meet specific customer needs. The Union Tool Corporation
specializes in packaging its standard roller coating features to fit
individual needs. If you provide us with your requirements, we will
provide you with a roller coater to do the job.
