When Bottling isn’ t the Bottleneck
In drinks manufacturing, improvement efforts tend to focus on filling, changeovers, labelling and inspection. These stages attract close attention, and rightly so. They are critical points in the process where small inefficiencies can quickly multiply.
In practice, productivity is often lost elsewhere.
In many plants, once a product is sealed, boxed or palletised, it becomes easier to handle. Hygiene restrictions reduce, tolerances widen and the task shifts from precision processing to straightforward movement. Yet this is often the point at which highly engineered systems give way to very traditional ways of working.
Finished cases accumulate at the end of conveyors. Pallets queue for collection. Skilled operators walk significant distances to move goods between packing, storage and despatch. Fork lift trucks carry out frequent, short movements that add no value to the product itself, but still absorb time, labour and floor space.

Capital investment typically concentrates on the core process, where performance is most visible and easiest to justify. End-of-line movement is often treated as an operational issue to be managed day to day, rather than as a process in its own right. Fixed automation can be difficult to justify in areas where layouts change, volumes fluctuate or seasonal peaks dominate.
The result is that the bottleneck is not the bottle, but what happens next.
Autonomous vehicles provide a practical way to address this gap, enabling packaged product to move through wrapping, storage and despatch without the extra handling and vehicle movements that often sit outside the main production flow.
These repetitive, low-skill tasks are well suited to automation. By removing routine material movement, operators can focus on quality, coordination and other value-adding work rather than transport between processes.
What often determines whether this type of automation is considered is not technical capability, but commercial risk. A pay-per-hour model changes that equation. Instead of committing capital based on projected returns, automation can be deployed in live conditions and assessed on actual performance.
Costs are linked to productive hours, with capacity able to scale in line with demand. For drinks producers managing promotions, seasonal volume changes or frequent format variation, this flexibility is significant.
There is also a workforce consideration that is easily overlooked. End-of-line handling is physically demanding and repetitive, yet it often relies on experienced people who could add greater value elsewhere. When autonomous vehicles take on routine movement, skilled staff spend more time on quality, coordination and continuous improvement.
In practice, productivity gains are often achieved not by pushing
