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 />
