How it Works
A Pick-to-Light
system uses rack mounted lights,
often divided into zones, to
direct operators to specific
stock locations. Each SKU can
have an individual numeric
or alphanumeric display with
a light, an acknowledgement
button, and a digital readout
for indicating quantity. Other
configurations allow fewer
or more simplified displays
to reduce the total cost.
In a typical
system, a picking sequence
starts at the beginning of
a zone where the operator scans
a bar coded address label attached
to the shipper, carton or tote.
The displays tell the operator
which SKUs to pick and how
many. The operator confirms
picks via acknowledgement buttons.
Where it
Fits
A Pick-to-Light
system can be designed to cover
a broad range of picking activity.
It's often thought of for applications
with a low number of SKUs and
a high number of picks per
line item. Yet it has also
been applied quite successfully
to extremely large applications
with thousands of SKUs. It
can be used for split case
or full case operations. Pick-to-Light
can be supplemented with a
discrete RF system in zones
with the slower moving SKUs,
full case, or full pallet applications. |
