Using
Motorola
fixed and
mobile RFID
readers,
BizSpeed
helped Knox
Nursery
deliver a 12
month
payback on
work in
process (WIP)
and
inventory
management.
Knox Nursery
is a
wholesale
nursery
based in
Winter
Garden, FL.
As a
wholesale
grower, Knox
has
approximately
8 acres of
greenhouse
space where
seasonal
variety
plants are
grown to
order and
shipped
across the
US. Half the
plants are
shipped via
FedEx and
half are
shipped via
truck.
Each order
has to
tracked
through the
whole
growing
process �
which is the
nursery
equivalent
of a
manufacturing
process.
Trays are
planted via
conveyor
belts, where
the process
automatically
runs a
Print-and-Apply
barcode to
attach an
serialized
barcode and
encoded RFID
tag.
BizSpeed
worked with
Knox Nursery
IT Staff to
integrate
RFID
tracking
into their
existing
manufacturing
WIP and ERP
software.
The
integration
points
included:
-
RFID
encoding
station
to
encode
and test
barcode
labels
with
RFID
serial
number.
Includes
a
touchscreen
PC with
an
optical
scanner
to
activate
the
encoder.
Upwards
of
20,000
trays
can be
encoded
each
week.
-
RFID
scan to
inventory
� as
trays
roll
into the
greenhouse,
the RFID
reader
confirms
entry
into
production
and
updates
the
inventory
tracking
status.
-
Mobile
RFID
scanner
to take
inventory
of
locations
� this
is done
by
location
table
(42
trays at
a time)
with
wireless
queries
to the
inventory
system
for
updates.
-
Mobile
rework
tracking
with
barcodes
� when
trays
contain
plugs
(seeds)
that
need to
be
disposed
or
consolidated
to a
different
tray for
further
growing,
they
rework
and
consolidated
trays
are
scanned
with a
barcode
and the
inventory
system
is
updated
wirelessly.
These
are done
via
barcode
due to
the
close
proximity
of RFID
tags and
the need
to
uniquely
identify
each
tray.
-
RFID
shipping
� two
shipping
portals
were
implemented.
Each
receives
approximately
50% of
the
shipping
traffic.
-
RFID
Rack
Shipping
� for
large
orders,
trays
are
shipping
in racks
via
truck.
The
shipping
area a
group of
portals,
each
with a
touchscreen
and
alert
light +
alarm.
The
operator
uses the
touchscreen
to
select
the
order to
ship.
The
screen(s)
then
show all
products
on the
order
and as
the
trays
are
moved
through
the
portal,
the ship
count is
decremented.
If a
tray is
not
supposed
to be on
that
shipment,
the
alarm
sounds
so the
shipper
knows to
stop and
remove
the
tray.
Once
complete
the
shipper
touches
the
screen
and a
shipping
list is
printed.
-
RFID
FedEx
Shipping
� for
smaller
orders,
trays
are
shipped
via
FedEx.
The
operator
uses a
touchscreen
to
select
the
order
and the
box
sizes.
The
touchscreen
shows
the
items on
the
order
and as
the
shipper
moves
the
items on
the
conveyor
past the
reader,
the
order is
updated.
Once
complete,
the
operator
presses
the �box
filled�
and the
shipping
system
access
fedex.com
to
generate
the
shipping
label in
real-time.
A second
label is
printed
with the
package
contents
and both
labels
are
attached
to the
box.
Customers
can
receive
the
FedEx
tracking
numbers
for
tracking.
-
RFID
mobile
inventory
portal �
trays
move all
through
the
greenhouse
during
their
growing
season.
A mobile
portal
was
implemented
to allow
scanning
all
trays
that
pass the
portal
and
recording
their
table
(inventory
location)
and
serial
number.
RFID is a very
good fit for the
nursery
industry.
Barcodes allow
scanning of
individual
trays, but in
bulk it is too
cumbersome and
difficult
because the
barcodes get
covered with
water, dirt,
leaves, etc. and
each one must be
cleaned to read
it. RFID allows
quick, accurate
scanning without
requiring direct
line of site.
The project was
started with a
pilot and RFID
site survey.
These are
critical to
understand
RFID�s
effectiveness in
your
environment. One
example of the
pilot�s findings
was that we
could not read
all tags once
trays were put
in a rack � we
could only read
approximately
85% due to the
rack acting as a
Faraday cage.
This helped in
the process
design to scan
trays before
entering the
rack.
Knox Nursery was
able to achieve
close to a one
year payback.
Knox and
BizSpeed are
marketing the
RFID integration
components and
GrowersOwn
(Knox�s Nursery
ERP system) to
other growers.
