Packhouse takes<br />
lead with robotics<br />
As the kiwifruit picking season met its frenetic peak in late<br />
May, Apata Group managers were busy monitoring key robotic<br />
technology just commissioned to help deal with the growing<br />
challenge <strong>of</strong> staffing in the sector.<br />
By RICHARD RENNIE<br />
This season marked a<br />
significant first for<br />
some state-<strong>of</strong>-the-art<br />
technology installed by Apata<br />
Group, one <strong>of</strong> the region’s<br />
leading post-harvest operators.<br />
It is the culmination <strong>of</strong><br />
more than $15 million spent<br />
in the past few years upgrading<br />
its packing facilities.<br />
Production manager Hans<br />
van Leeuwen said close liaison<br />
between two key European<br />
fruit sorting and packaging<br />
companies - Maf Roda <strong>of</strong><br />
France and Niverplast <strong>of</strong> the<br />
Netherlands - has delivered<br />
Apata with some bespoke<br />
equipment. The technology<br />
was the first <strong>of</strong> its kind in<br />
kiwifruit processing anywhere<br />
in the world, he said.<br />
“Some <strong>of</strong> this technology<br />
has been employed in other<br />
areas, like apple packing, but<br />
they are very excited about<br />
the opportunities on <strong>of</strong>fer<br />
here in New Zealand with<br />
kiwifruit.”<br />
The company’s Mends<br />
Lane pack-house east <strong>of</strong> Te<br />
Puke has had two high speed<br />
sorting systems running for<br />
the past three years, each<br />
capable <strong>of</strong> checking and<br />
grading 7000 trays an hour.<br />
Using leading-edge near<br />
infra-red camera technology,<br />
the lines photograph each<br />
piece <strong>of</strong> fruit with a dozen<br />
different light spectrums,<br />
determining quality parameters<br />
including brix levels, dry<br />
matter and flesh colour.<br />
Algorithms can then calculate<br />
what grade that fruit<br />
is, based on the behaviour <strong>of</strong><br />
the light spectrums hitting the<br />
fruit. Weigh technology can<br />
weigh 60 fruit a second 30<br />
times for weight accuracy to<br />
one tenth <strong>of</strong> a gram, before<br />
splitting it <strong>of</strong>f onto packing<br />
benches.<br />
For us it is a case <strong>of</strong><br />
focusing on what we<br />
can do on the floor,<br />
and re-allocating that<br />
finite resource <strong>of</strong><br />
people to picking.<br />
- Stuart Weston<br />
However, in light <strong>of</strong> growing<br />
crop volumes and evertightening<br />
labour supply, the<br />
company was looking to push<br />
automation and robotics further<br />
down the packing line,<br />
into the labour intensive areas<br />
<strong>of</strong> folding, packing and sealing<br />
fruit cartons.<br />
In past weeks van Leeuwen<br />
and his colleagues have<br />
been overseeing the commissioning<br />
<strong>of</strong> a Maf Roda robotic<br />
packing machine.<br />
In what van Leeuwen said<br />
was a world first, the machine<br />
has been developed to pick up<br />
the required number <strong>of</strong> kiwifruit<br />
via air suction and gently<br />
place them in their single<br />
layered flat tray, in amounts<br />
ranging from 24-34 per tray.<br />
“Our best packer will<br />
do three trays a minute, the<br />
machine will do 22.”<br />
Meantime the larger 10kg<br />
bulk boxes are now also<br />
packed by robotic box fillers,<br />
which allocate the correct<br />
weight <strong>of</strong> fruit, level it <strong>of</strong>f<br />
and seal the box up before<br />
finally placing a full traceability<br />
label on its side.<br />
“Even the labelling, which<br />
may seem a simple enough<br />
job, is hard to do manually<br />
in a repetitive consistent<br />
way. It is some <strong>of</strong> these small<br />
changes that soon add up.”<br />
Van Leeuwen said the<br />
two key priorities for robotic<br />
use were to increase packing<br />
speed within the typically<br />
limited space constraints that<br />
every pack-house had.<br />

Improving productivity<br />
“We are finding these machines <strong>of</strong>fer<br />
us a compact footprint. And while it is<br />
early days, productivity is promising.”<br />
He and Apata Group chief executive<br />
<strong>of</strong>ficer Stuart Weston stressed the technology<br />
was not putting staff out <strong>of</strong> work,<br />
but rather giving the company the opportunity<br />
to reallocate the positions.<br />
“For every worker in the orchard<br />
there are 2.5 in the pack house. So for<br />
us it is a case <strong>of</strong> focusing on what we<br />
can do on the floor, and re-allocating<br />
that finite resource <strong>of</strong> people to picking,”<br />
said Weston.<br />
Automation is playing out in two<br />
arenas within the industry at present,<br />
within pack houses and on orchards<br />
with the design and construction <strong>of</strong><br />
autonomous harvesting platforms<br />
developed by Tauranga company<br />
Robotics Plus.<br />
Weston said all post-harvest processors<br />
are facing the same issues <strong>of</strong> labour<br />
constraints, with the overheads in securing<br />
and housing labour quite prohibitive.<br />
“We are told we will need about<br />
another 6000 in coming years, and no<br />
one really seems to know where we<br />
would get them from, and where we<br />
would even house them.”<br />
He said the industry had three key<br />
capital-intensive areas competing for<br />
funding as fruit volumes continue to<br />
grow. These are automation, staff accommodation<br />
and cool store facilities.<br />
“This pack house [Mends Lane] is<br />
something <strong>of</strong> a beta test bed for new<br />
technology,” said Weston.<br />
“If we can get the pack house operating<br />
on a true 24/7 basis using this technology,<br />
we stand to increase its productivity<br />
by 50 percent.”<br />
