Arnott’s World Fastest Mix Pack Line

Australia's beloved biscuit maker partnered with Applied Robotics to develop a world-first fully automated assorted biscuit packaging system, transforming a repetitive manual process. Processing up to 105 biscuits per second, it set new standards and strengthened local manufacturing.

Complex assorted packs proved an automation puzzle

Since 1865, Arnott’s has delighted Australian families with its iconic range of biscuits. With over 1,045 products manufactured across 16 sites employing more than 4,000 people, Arnott’s proudly sources 75% of ingredients locally in Australia and New Zealand.

Since the 1960s, Arnott’s has pioneered the automation of their baking and packaging processes for single-variety biscuits. However, assembling the popular assorted packs presented a seemingly impossible automation challenge, requiring individual placement by hand.

Assorted packs demand repetitive, labour-intensive processes

From Cream Favourites and Family Favourites to High Tea Favourites and the Cheeseboard Cracker Assortment, these beloved packs feature biscuits such as Monte Carlos, Shortbread Creams, Delta Creams and various crackers arranged in dedicated vacuum-formed trays.


Unlike single-variety packs, which could be automatically packed directly from the production line, assorted packs required a complex and labour-intensive multi-stage process:

01

Bake each biscuit variety separately over multiple days

02

Store biscuits temporarily in airtight containers

03

Manually place each biscuit type into its designated cavity in the vacuum-formed tray

04

Package and distribute the completed packs

"With demand requiring 140 packs per minute, they needed hundreds of operators working across shifts to handle the manual packing," explains Dr Paul Wong, Founder and Technical Director at Applied Robotics.

“This labour-intensive process created challenging repetitive work while increasing production costs and making consistent quality difficult to maintain at such high volumes.”

Standard automation machines were not viable

Facing these challenges, Arnott’s initially approached their traditional European machinery suppliers from Germany and Switzerland, who had provided their single-variety packing equipment for decades.

However, assessing the complexity of delicately handling and placing unique shapes, sizes and delicate compositions into precise packaging, they deemed an automated solution unviable.

Facing higher local costs, Arnott’s was determined to find an innovative and cost-effective solution that could work alongside the existing workforce to maintain the manufacturing of these iconic Australian products on home soil.

“For Australian manufacturers, the challenge is clear – either innovate to stay competitive or risk losing production to overseas facilities.

Our objective was to help Legrand maintain and strengthen their local manufacturing capabilities through intelligent automation.“- Andrew Hambly, Solutions General Manager at Applied Robotics

World-first automation integrates 50+ robots and 64+ vision systems

After evaluating several potential partners, Arnott’s partnered with Australian-owned Applied Robotics to tackle this unprecedented challenge. Rather than adapting existing machinery designs, Applied Robotics developed an entirely new concept centred around advanced robotics, machine vision and an end-to-end approach.

“The traditional European suppliers viewed the problem through the lens of conventional biscuit machinery,” says Andrew Hambly, Solutions General Manager at Applied Robotics.

“We approached it differently, leveraging vision systems and robotics to create a system that could replicate and improve upon the quality and consistency of human operators, while dramatically increasing throughput.”

Proof-of-concept before end-to-end development

As they were in uncharted territory, Arnott’s and Applied Robotics started with a six-month feasibility study to confirm the approach would work at scale. The team built and tested a single cell that could handle one biscuit variety with the necessary speed, precision and quality control.

After extensive testing proved the concept viable, they built the complete system that transformed the entire assorted pack production process:

01

Baking line unloading robots

  • Three specialised robotic cells unload freshly baked biscuits from the production line
  • Vision systems inspect each biscuit for quality, size and appearance
  • Robots place biscuits into custom-designed storage trays

02

Airtight storage system

  • Sealed trays maintain freshness until each variety is needed
  • Automated tracking system manages inventory of each biscuit type
  • Robotic palletising system stacks and retrieves trays as needed

03

Assorted pack-filling cells

  • Eight specialised cells along the conveyor handle individual varieties
  • Custom grippers with force-feedback servomotors provide a feather-like touch that mimics human dexterity
  • Vision systems verify biscuit quality, cream distribution and structural integrity

04

Integrated packaging line

  • Filled trays proceed through metal detection, flow wrapping and cartoning
  • Automated case packing and palletising systems prepare products for distribution
  • Used storage trays are washed, dried and returned to the system

05

Central control system

  • Manufacturing Execution System (MES) coordinates all processes in real-time
  • Production data gathered for analytics and optimisation
  • Flexible programming for rapid changeover between pack configurations

"What makes this system remarkable is not just its scale, with 100+ robots and vision systems, but the way it also integrates storage trays, metal detection, quality assurance and washing systems to work seamlessly together from start to finish," says Dr Wong.

Machine vision ensures quality control

A critical innovation was implementing advanced vision systems that could replicate and improve upon human quality inspection. These systems verify:

01

Correct biscuit size, shape and colour

02

Proper cream distribution in sandwich biscuits

03

Absence of breaks or damage

04

Consistent positioning within trays

"The vision systems are so precise they can detect even subtle variations in cream distribution or tiny cracks that might be missed by human inspectors, especially after hours on the production line"
