Before You Start
As-Built Documentation This manual does not contain as-built documentation. Obtain as-
built documentation from your direct supplier. If you purchased
your tooled feeder directly from Hoppmann Corporation, you will
automatically receive as-built toolin and chan eover
documentation in your System Operations Manual.
Tools You Will Need The model FR-20 and FR-30 feeders are offered in both ANSI and
metric versions. For maximum compatibility, ANSI units are
classified as “soft ANSI” construction, meanin that metric threads
and hardware are used throu hout. Both metric and ANSI units
require metric tools for repair and/or adjustment. If your direct
supplier tooled your metric feeder with ANSI hardware, you will
need ANSI tools as well.
Any part of the feeder that touches your parts has been precision
tooled to match your parts. Do not move tooling or change feeder

Feeder Description & Specifications
Overview of the FR-20 & FR-30
FR-20 vs. FR-30 The FR-20 & FR-30 Centrifu al Feeders unscramble, feed and
orient product. Simply put, it delivers ali ned product. Except for
obtainable rates and the size of product, the FR-20 and FR-30
function identically. Generally, the FR-30 is used to handle lar er
product or achieve hi her output rates.
Operation Step 1ÑThe Feeder Accepts Your Product. Every FR-20 and
FR-30 operates in the same basic way. The feeder accepts product
from a separate bulk supply hopper or prefeeder. Product drops
randomly into the bowl, a few at a time. (Shibuya Hoppmann
centrifu al feeders function best when product is carefully metered
from bulk by a prefeeder.)
Step 2ÑThe Feeder Loads and Qualifies Your Product. After
droppin into the bowl, product in the desired orientation is
pushed up the stationary ramp. This process may be assisted in
some applications by compressed air. After the product has been
pushed up the ramp, it is loaded onto the movin rim of the bowl.
The rim moves the product past mechanical, pneumatic and/or
optical qualifiers which reject product that are not in the desired
orientation. Improperly oriented product are recirculated.
Step 3ÑThe Feeder Delivers Your Product. Finally, product
moves off the bowl's rim and out of the feeder in the proper
orientation, in a rapidly movin and in a randomly spaced stream.
Shibuya Hoppmann centrifu al feeders deliver product almost
immediately, so parts simply don't have time to et scuffed up.
Rate Shibuya Hoppmann feeders typically handle product at rates
between 20 and 2000 parts per minute. Your particular product’s
characteristics and your desired production speed will affect the
output rate.

Safety Precautions
2
Warnings & Cautions
Turn Off Power! Before servicin , make sure you have turned off
compressed air and electrical power in a way which prevents
accidental reactivation. Padlock and clearly ta the appropriate
electrical and pneumatic disconnects. Lockout/ta out procedures
are covered in United States Code of Federal Re ulation (CFR)
Title 29 Part 1910.147, “The Control of Hazardous Ener y.”
DressAppropriately! Reduce the risk of injury from movin parts
by securin loose sleeves and other clothin . Don’t wear loose
jewelry or neckties near the feeder. Wear safety lasses or other
protective eyewear when servicin the feeder. Never place hands
or tools in the feeder when it is operatin .
InstallSafetyCovers! Make sure the feeder remains safe to operate.
Be sure all safety covers have all been installed before returnin the
feeder to normal operation. Safety covers on the FR-20 and FR-30
feeders include any covers installed by your direct supplier, as
well as the exit area cover (which protects the operator from
movin sprockets and belts.)
Operating & Maintenance: Do's & Don'ts
DonÕt Give the Feeder Too Much Product. Don’t overload the
feeder, or it may jam or lose rate. Product must be carefully
metered into the feeder from bulk. Allow only enou h product
into the feeder to keep the line runnin at the required rate.
DonÕtRuntheFeederTooFast. Don’t run the bowl faster than the
linear feet per minute recommended by your direct supplier. If you
do, the orientation qualifiers cannot function as efficiently, and the
feeder may jam or lose rate.

12
FR-20 & FR-30 Feeder Installation/Maintenance
DonÕtAdjustAirJetFlowControls. It’s okay to adjust the main air
re ulator to its correct settin for your installation. However, air
jets and their individual flow controls have all been carefully preset
to work with your product; they should never need adjustment. If
you move air jets or adjust their individual flow controls, the
feeder may jam or lose rate.
DoPerformPreventiveMaintenance. To keep the feeder runnin
without unexpected repairs and resultin “down” time, re ularly
perform the preventive maintenance procedures in Chapter 4.
Do Carefully Replace Any Tooling You Remove. To ain access
for repairs, you may need to remove toolin . Because Shibuya
Hoppmann and your dealer or OEM have no control over such
activities, they can not be responsible for any toolin you remove.
Carefully document the position of any tooling before you begin.
If you fail to replace all toolin exactly as it was, you may create
difficult and time consumin problems for yourself.
Don'tInstalltheFeederNearFlammableGas,VapororDust. Do
not instal a feeder in these conditions unless you install additional,
approved explosion-proof or dust i nition-proof enclosures.
Without such additional enclosures, normal sparkin of the brushes
inside the motor could i nite flammable as, vapor or dust.

Installation & Startup
Unpacking & Inspection
Step 1ÑInspect & Unpack the Crate. Remove packin materials
from sensors, toolin and movin parts. Make a visual check to be
sure parts have not come loose durin shippin . If you find any
concealed dama e, call the shippin carrier and your direct sup-
plier immediately. Don’t attempt to fix the problem yourself
unless told to do so by your direct supplier.
Step 2ÑRecord Serial Numbers. If you have not already done so
record, on the front of this manual, the feeder's model and serial
number.
Physical Setup
Step 1ÑPosition the Feeder. Place the feeder as shown on the
equipment layout drawin provided by your direct supplier.
Step 2ÑLevel the Feeder. Usin a carpenter's level, adjust the
levelin feet. Ti hten the locknuts on the levelin feet. (In some
applications, levelin feet are not used because the feeder is
connected directly to other framework.)
Step 3ÑConnect Your Output Device. Check that product can
move smoothly from the exit of the feeder to your output device
(deadplate, conveyor, ravity track or powered rollers, i.e.). Ensure
that product won’t jam or lose their orientation as they move to the
output device.
Step 4ÑPosition the Prefeeder. Now, place your bulk supply
hopper or prefeeder into position. Follow the equipment layout
drawin provided by your direct supplier, or the feeder may not
operate correctly. If you are providing your own prefeeder, continue
reading. Otherwise, skip to Step 5.

14
FR-20 & FR-30 Feeder Installation/Maintenance
If you are supplyin your own prefeeder, you are responsible for:
▲
Providin and installin the feeder's bowl level switch so it can
control the product flow of your prefeeder.
▲
Settin the timin delay for the feeder's bowl level switch.
▲
Correctly positionin the prefeeder. Generally, the prefeeder
must dischar e product to fall on the lowest side of the feeder's
disc, halfway between its center and its outside diameter. Take a
handful of product and drop them from the snout of your prefeeder
into the feeder bowl. Avoid product bouncin up off the disc onto
the rim of the feeder bowl, this could disturb properly oriented
product. Reposition the prefeeder (as often as necessary) until
product lands correctly.
Step 5ÑConnect Power and Air. Connect your feeder to main
power and compressed air (if applicable). Don't chan e the feeder’s
main air re ulator; it should already be correct when you receive
the feeder.
Starting the Feeder for the First Time
Step 1ÑSecure Safety Covers and Clothes. Before turnin on
power and air, make sure safety covers are in place and that you are
dressed appropriately for safety.
Step 2ÑTurn on Power and Air. Turn on the feeder’s power. If
applicable, turn on the feeder’s main air re ulator.
Step 3ÑCheck for Rubbing Parts. Run the prefeeder, feeder and
output device without product. In the unlikely event that you hear
squeaks and squeals (there should be none), shut down immediately
and check for any remainin packin , such as between the backup
rin and the rim of the bowl.

15
How to Set Proper Bowl Speed
Ask your direct supplier for the actual linear feet per minute at
which the bowl should rotate. For reliability, set the bowl to match
that speed.
▲
To set bowl speed, you will need a hand-held tachometer (analo
or di ital) with a surface speed wheel indicator (see Fi ure 5-1).
▲
This procedure is performed with the power on and the feeder
operatin . If your direct supplier has installed a cover over the
bowl, you will need to open it before proceedin .
Step 1ÑTurn on Feeder. Turn on the feeder and run it without
product.
Step 2ÑSet Bowl Speed. To set the bowl speed, place the hand-
held tachometer (with surface speed indicator attachment) on the
inner wall of the movin bowl, at its most upper inside diameter.
Adjust the bowl speed until the bowl is movin at correct number
of linear feet per minute (FPM).
Step 3ÑRecordNewSettings. Turn off the feeder. Mark dial plate
with new settin and remove any old marks.

FR-20 & FR-30 Feeder Installation/Maintenance
Running Product For The First Time
Step 1ÑVerify Changeover Setup. If your feeder is tooled to run
multiple product, ensure the feeder is set up for the product you
want to run.
Step 2ÑInspect Product at Exit. Inspect the exit of the feeder. If
product is exitin the feeder properly oriented, at the required rate
and without jammin , then installation is complete. Otherwise,
continue with Step 3. Atthispoint,donotadjusttheflowcontrols
on any air jet.
Step 3ÑVerifyPrefeederSpeed. Normally this step is completed
by your direct supplier; however, if you are providin your own
prefeeder, you'll have to set the prefeeder's speed. To do this, turn
the prefeeder's speed control all the way down, then turn on the
feeder.
▲
Slowly, raise the prefeeder's speed control (you may need to
take several minutes) until enou h product exits the feeder to keep
the line runnin at the required rate.
Stopraisingtheprefeederspeedwhenenoughproductisexitingthe
feeder. If you don't stop raising the prefeeder speed, you will
overload the feeder and reduce its output.
General Tips
▲
After your feeder is set up and runnin , observe the flow of
product at each transition point. Later, if a problem occurs, observe
these transition points to help pinpoint the cause.
▲
Listen to the way the feeder sounds when it is runnin properly.
If it suddenly sounds different, investi ate why.

General Cleaning
Outer Frame The Hoppmann Model FR-20 & FR-30 Centrifu al Feeders are not
& Tooling intended for washdown use. If you need to clean the outer frame,
safety covers or toolin , use a mild household cleaner.
Bowl & Rigid Disc: The bowl and ri id disc are self-cleanin when handlin most
"Dusty" Applications product; however, if your product enerates dust or particulate
when handled, clean the feeder as often as necessary. For such
product, remove dust from the top surface of the rim of the bowl
and the ri id disc with a portable vacuum cleaner or dry compressed
air.
Lubrication
Bearings On all FR-20 and FR-30 models, rease nipples for lubrication are
located on the outside of the upper and lower spindle bearin s.
Use any lithium rease conformin to NLGI Grade 2 consistency;
the rease should be free of dust, particles and abrasives.
Instead, use the maximum rease capacity of the bearin s as a
uide; the upper spindle bearin can hold up to about 3/8 ounces
of rease; the lower spindle bearin can hold up to about 1/8 ounces
of rease. Lubricate every 6 to 12 months or 1000 operatin hours,
whichever comes first.
Because of the danger from moving parts, do not lubricate while
the feeder is operating.
Chain & Sprockets After reasin the bearin s, rease the drive chain, spindle sprocket
and torque limiter sprocket every six months or 1000 operatin
hours, whichever comes first. Use standard Moly rease, Lubriplate
#3000 (NLGI Grade 2) or equivalent.

Adjusting Bowl Runout
Bowl runout needs to be set if the bowl is removed. Adjust runout
with power off and drive chain disen a ed. For runout specifica-
tions, see Chapter 1.
Step 1ÑGain Access. Disconnect power and air. Remove the
cover from the exit area of the feeder.
Step 2ÑRemove Drive Chain. Remove the master link. Discon-
nect the drive chain from the spindle shaft sprocket.
Step 3ÑAdjust Vertical Runout. Attach a dial indicator to the
inside of the feeder frame. Set the indicator contact point vertical,
restin on the top of the rim of the bowl, up to 1/4" (6 mm) from the
bowl's upper inside diameter (ID). Loosen the jam nuts and
locknuts (above and below) each arm of the bowl spider, one arm
at a time. Repeat as necessary while checkin runout. Don’t ti hten
the jam nuts until Step 4.
Donotadjustspiderrimsupportarmswithoutmonitoringrunout,
because if you misalign any one spider rim support arm, you may
damage the feeder bowl.
Step 4ÑAdjust Horizontal Runout. Move the indicator contact
point horizontal, restin on the inner wall of the bowl, up to 1/4" (6
mm) from the bowl's upper ID. Gently tap the bowl’s ID with the
palm of your hand or a rubber mallet. Inspect vertical runout and
adjust a ain if necessary. Continue alternatin between horizontal
and vertical runout until both are within specification. Ti hten
locknuts and jam nuts by hand firmly but not forcibly.
Step 5ÑCheckExit. Ensure that the proper relationship still exists
at each transition between the rim of bowl and output device
(deadplate, conveyor, ravity track or powered rollers, i.e.).
Step 6ÑCheckBackupRingClearance. Ensure that the proper as-
tooled ap still exists between the bottom of the backup rin and the
rim of the bowl.
