BOWL DRIVER GENERAL INSTRUCTIONS
CONTINUED
Installaon
All base units are factory adjusted and ready for assembly
of the bowl to the base unit top casng. The screws on
the rubber feet at the boom of the base casng should
be snug but not distort the rubber.
Assemble the feeder bowl to the base unit top casng.
Center-mounng is the most common method; however,
some units have provisions for top-mounng or boom-
mounng (using 3-8 screws instead of one). Bowl
mounng screws are provided with the bowl. Do not sub-
stute other screws for those supplied.
Wiring
Base units without power cords must be connected to the
feeder coil through a hole in the base casng. ADI recom-
mends type SO or SJO three-conductor cord, from 16
gauge to 14 gauge, depending on the amperage of the
feeder coil. Smaller feeders are factory wired with SJO
cords. If the base unit has a hinged metal cover, put it
back on aer compleng wiring. If le o, the feeder am-
plitude may be aected. To power our units, we manufac-
ture controllers for all of our feeders.
Operaon
It is not necessary to have an in-depth knowledge of vibra-
tory feeders to operate and maintain them. Reading the
balance of these instrucons will provide informaon fun-
damental to your success with feeders. Refer to the as-
sembly drawing provided as we explain how a vibratory
parts feeder works.
When power is applied to the coil, the armature is aract-
ed to it. This pulls the top plate down and causes the
springs to ex. Since the springs are on an angle, the top
rotates as it moves down. A bowl secured to the top plate
will follow the acon of the top plate.
When power is removed from the coil, the springs re-
turn to the top plate to its original posion. This acon
is repeated 3600 mes per minute - so fast you cannot
see the bowl and the top plate move. Any parts placed
in the bowl rotate around the inside oor of the bowl,
work their way toward the outside wall, climb the
track, and discharge from the bowl. The parts are ori-
ented as they move up the track and pass through con-
trolled obstrucons (known as tooling) aached to the
walls and tracks of the bowl.
The springs on a base unit are selected at the factory to
accommodate a given weight and size of bowl. Make
sure you know which bowl goes on which base unit.
With the controller power switch in the ON posion,
slowly turn the potenometer clockwise. Watch the
parts in the bowl. Parts should move through the bowl
fast enough to meet requirements, but not fall o the
tracks or constantly be rejected by the bowl tooling.
Coil Adjustment
Adjustment of the coil is rarely necessary. The arma-
ture should never be allowed to strike the coil. There
should always be a gap between the coil and the arma-
ture when the base unit is operang at maximum feed
rate. Look at the drawing of your base unit. Models 3,
5, and 8 use a single screw to adjust the gap. Turning
that screw clockwise moves the coil down, increasing
the gap between the coil and the armature.
The coil assemblies on Models 10, 15, 20, 25, 30, and
35 sit on four threaded studs. Lock nuts, above and
below the mounng plate, x the posion of the coil
assembly on the studs.
Checking Performance
Vibratory parts feeders are reliable and generally give
extended service without needing repairs. Periodic
inspecon will make a great deal of dierence not only
in feeder performance, but more.
