Summary: End-of-line automation should be designed as one connected production system. A good project brief covers products, throughput, secondary packaging, conveyors, palletizing, load securing, pallet handling, controls, safety, utilities, maintenance, testing and future growth. This checklist gives manufacturers a structured way to define the project before equipment is selected, helping reduce integration gaps and avoid moving a bottleneck from one stage to another.

Many automation projects begin with a machine request: “We need a palletizer,” “We need a faster wrapper,” or “We need conveyors.” The real requirement is usually broader. The manufacturer needs finished products to move from the production line to a stable, secured pallet and then toward storage or dispatch at a predictable rate. That is why end-of-line packaging automation should be planned around the complete flow rather than as separate equipment purchases.

1. Define the End-of-Line Starting and Finishing Points

First decide exactly where the automation scope begins and ends. Does it start when an individual product leaves the filler? After a bag is sealed? After a case is formed? Does it end at a wrapped pallet, at warehouse hand-off or after truck loading? Clear boundaries prevent interface responsibilities from being missed.

Document the process sequence

A typical end-of-line flow might be: primary pack → secondary packaging → product conveyor → inspection → palletizing → pallet conveyor → wrapping or strapping → storage/dispatch. Bulk products may instead move through automatic bagging before palletizing. Other products may require case packaging before they are ready for the palletizer.

2. Build a Complete Product and Packaging Matrix

Automation cannot be designed accurately around a single “typical” product if production handles a much wider range. Create a matrix that includes current products and credible future variants.

Record for every SKU

• Length, width, height and weight.
• Primary and secondary packaging material.
• Fragility, rigidity and surface conditions.
• Required orientation during transfer.
• Cases, bags, bottles, drums, pails, crates or other handling format.
• Permitted compression, gripping or vacuum contact areas.
• Pallet pattern and layer requirements.
• Expected production rate.

3. Define Normal, Peak and Future Throughput

Design against real production behaviour. The daily average can hide short periods of much higher output. Capture normal rate, peak rate, shift pattern, changeover frequency and the expected production rate after planned upstream improvements.

Key throughput questions

• How many units, cases or bags leave the upstream line per minute?
• How many pallets must be completed per hour?
• How long is each pallet unavailable during changeover?
• Which downstream process has the slowest cycle?
• How long can upstream production continue if the downstream process stops?

4. Identify the Current Bottlenecks and Manual Touchpoints

Walk the existing process and record where queues form, where operators repeatedly lift products, where forklifts enter production areas and where quality problems occur. Automating a stage that is already faster than the rest of the line may provide little benefit. Prioritise the constraint that limits throughput, consistency or safe working conditions.

5. Define Secondary Packaging Requirements

If products need to be grouped or protected before palletizing, define the case or secondary packaging process. Consider case style, product count, orientation, closing method, changeover and inspection. Case packaging solutions should deliver a consistent unit that downstream conveyors and palletizers can handle reliably.

6. Design Product Conveying and Accumulation

Conveyors must do more than connect machines. They control product spacing, merging, accumulation, orientation and presentation. Select the intralogistics conveyor system around product behaviour and the required line logic.

Conveyor checklist

• Product dimensions and contact surface.
• Required conveyor speed and spacing.
• Curves, merges, transfers and elevation changes.
• Accumulation before bottleneck machines.
• Washdown, dust or environmental conditions.
• Sensor positions and jam detection.
• Operator crossing points and maintenance access.

7. Select the Palletizing Architecture from the Application

The palletizer should be selected only after product, throughput and layout are understood. Alligator Automations Australia offers robotic palletizing, gantry palletizing and other palletizing solutions. Each architecture has different strengths in flexibility, payload, footprint, product handling and pattern formation.

Palletizing checklist

• Product weight and packaging behaviour.
• Number of infeed lines.
• Number of pallet positions.
• Required patterns and layer sheets.
• Empty-pallet supply method.
• Gripper or end-of-arm tooling requirements.
• Pallet changeover time.
• Guarding, access and maintenance.

8. Design Pallet Flow After Palletizing

A full pallet needs somewhere to go. Define whether it will be removed by forklift, transferred automatically to wrapping, sent to storage or prepared for loading. Pallet conveyor systems and pallet handling solutions can create controlled movement between these stages and reduce repeated manual transport.

Pallet-flow checklist

• Pallet dimensions and underside construction.
• Maximum completed load weight and height.
• Required transfer orientation.
• Buffer positions between palletizer and wrapper.
• Turntables, chain transfers or lift-and-turn devices.
• Forklift hand-off or warehouse interface.

9. Define Pallet Securing and Packaging

Stable stacking is only one part of transport readiness. The finished pallet may need stretch wrapping, strapping, stretch hooding or another load-securing method. Pallet packaging systems should be selected according to load stability, pallet dimensions, throughput and distribution requirements.

The wrapper or strapper must also be capacity-matched to the palletizer. If the palletizer completes loads faster than they can be secured, provide suitable accumulation so the line does not stop repeatedly.

10. Consider Dispatch and Automatic Truck Loading

If finished pallets leave the end-of-line area faster than they can be loaded, the loading dock can become the next bottleneck. High-volume facilities can assess whether automatic truck loading is appropriate for the transport flow, trailer/container types and site conditions.

11. Define the PLC, HMI and Data Architecture

Controls should coordinate all machine states and make the line understandable to operators. Define who owns the master sequence, how machines exchange signals, how recipes are stored and what happens during faults.

Controls checklist

• Ready/busy/fault signals between machines.
• Product and pallet presence sensing.
• Buffer-full and buffer-empty logic.
• Recipe and SKU selection.
• Alarm history and diagnostics.
• Production counts and downtime data where required.
• Software backups and change management.
• Interfaces to existing plant systems where required.

12. Complete the Safety Concept Before Final Layout

Safety affects the footprint and sequence of the entire line. Guarding, gates, light curtains, scanners, emergency stops, safe-speed requirements, reset locations and maintenance access should be designed with the equipment rather than added after mechanical design is complete.

Safety checklist

• Hazardous robot or machine zones.
• Conveyor pinch and crush points.
• Operator loading/unloading points.
• Forklift and automated pallet traffic interaction.
• Safe access for jam clearing and maintenance.
• Energy isolation and lockout requirements.
• Restart behaviour after safety trips.

13. Confirm Utilities and Site Conditions

Verify electrical supply, compressed air, network requirements, floor loading, mounting conditions, ambient temperature, dust, moisture, washdown needs, ceiling height and any other environmental constraint. Site conditions can change component selection and installation scope significantly.

14. Protect Maintenance Access

A line that is compact on a drawing can be difficult to maintain in real life. Provide working room around motors, sensors, film rolls, grippers, belts, chains, electrical cabinets and other service points. Consider how technicians will safely remove a component—not only how the equipment will run when everything is healthy.

15. Define Changeovers Before Commissioning

Document how operators will switch products, cases, pallet patterns or recipes. Identify which changes are automatic, which require tool or guide adjustments and which require a controlled engineering modification. A good changeover process should be repeatable and understandable.

16. Plan for Future Capacity Without Overengineering

List realistic future scenarios: additional SKUs, higher throughput, a second production line, a new pallet size or added downstream equipment. Then identify reasonable provisions such as spare conveyor capacity, available PLC I/O, modular guarding, extra recipe storage or physical space for expansion.

17. Create a Factory Acceptance Test Plan

Define what the system must demonstrate before shipment. Use representative products and pallets wherever possible. The FAT should cover normal running, changeovers, fault behaviour, safety functions and agreed performance conditions.

FAT checklist

• Representative product range.
• Required production sequence.
• Pallet patterns and changeovers.
• Alarm and recovery tests.
• Safety-device operation.
• HMI screens and recipe functions.
• Data logging where included.

18. Define Site Acceptance and Ramp-Up

Site testing should confirm that the installed line performs with the real upstream process, utilities and operators. Allow time for tuning product transfers, conveyor spacing, gripper settings, pallet patterns and fault recovery. Commissioning should include a controlled ramp-up rather than assuming the first production shift will represent final stable performance.

19. Train Operators and Maintenance Teams

Operator training should include normal start/stop, recipe selection, jam recovery and safe fault reset. Maintenance training should cover diagnostics, inspection, preventive tasks, software backups and safe access. The goal is to make the customer team confident in running and supporting the asset after handover.

20. Measure the Results After Go-Live

Compare the project against the original objectives. Track the metrics that matter to the business, such as pallets per hour, line stops, manual touches, product damage, changeover time, labour redeployment, forklift movements or dispatch cycle time. This identifies further improvement opportunities and validates whether the project solved the intended problem.
