No errors during guided format change
Get it done faster, cheaper and safer with the GCS
Industry:Food and Beverage IndustryCustomer:Global Leader in Food Manufacturig
A global leader in food manufacturing had a specific need to improve production efficiency. After evaluating and piloting they decided to implement the Balluff "Guided Changeover Solution" on a coffee can labeling machine.
Situation
The machine handles five different can sizes ranging from the smallest at 400 g to the largest at 1700 g. The substantial size variations make changing formats challenging, especially when moving between the smaller and larger can sizes.
This particular production line has a high commercial demand and requires operating 24 hours a day. The machine with its twelve change points had become a bottleneck during changeover process, making it vital to reduce downtime in order to produce the required demand.
Challenge
The main challenge was to reduce format change downtime and improve ramp up of the production line after a completion of changeover. Every minute that is saved here can be used for more valuable production. It was also important to reduce training requirements and the need for experienced personnel. Good and skilled people are hard to find and also more expensive.
The overall challenge was to increase the productivity and profitability of this production line to produce more goods for less money.
Solution
The machine handles five different can sizes ranging from the smallest at 400 g to the largest at 1700 g. The substantial size variations make changing formats challenging, especially when moving between the smaller and larger can sizes. This particular production line has a high commercial demand and requires operating 24 hours a day. The machine with its twelve change points had become a bottleneck during changeover process, making it vital to reduce downtime in order to produce the required demand.
It only required three steps for the customer to realize the full benefit of the Guided Changeover Solution retrofit:
Identify the changeover points or centerlines
select and install the appropriate sensors
create step-by-step instructions for the operators in the Guided Changeover Solution software
How does it work?
The Guided Changeover Solution software guides them step by step through the format change process. Sensors provide immediate feedback about the change point positions and thus facilitate, accelerate and verify the correct settings of lengths, heights and widths.
With these instructions and the verification of the sensors, the required changeover time is now documented and consistent and not dependent on individual experience.
Every change point is set correctly, fine tuning (tweaking) so no longer necessary. This not only significantly reduces the time for format changes, but also makes the ramp-up much faster. At the same time mistakes are avoided and less waste is produced.
The labeler in question is an older model from the 1980s, with limited automation capabilities. However, as the "Guided Changeover Solution" is a standalone solution that does not disrupt the original machine controls, it was easily retro-fitted, effectively extending the lifespan of the machine with minimal investment.

We feel very comfortable with the solution and our operators have adapted well to it. The solution reduced the format change time from 80 minutes to 40 minutes. This was achieved through adequate training and coordination with Balluff. We will start implementing the solution in the next machine.
Benefits
You should use the Guided-Changeover-solution in your application because:
- The system is easy to use - by everybody. No experience needed.
- All manual changeover processes can be retrofitted with it.
- No mistakes possible - adjust and produce.
- Produce less waste in the ramp up - save money and our planet.
