TINE SA is Norway's largest producer, distributor and exporter of dairy products. Their goal is to provide their consumers with food that comes with a healthier and positive experience. It has been a long time since there was a dairy in almost every town and there will be fewer. However, the fear of closure is not an issue among the 115 employees at TINE Dairy Tretten. Here, the workforce is constantly being expanded while investing in new machines. On nine production lines, a number of cheeses are produced. But it is the various porridge products that account for really large volumes, with 100,000 cups of porridge per day.
Facts & figures
In 2016 the dairy at Tretten was moved to a completely new warehouse. Like in other TINE facilities, flows were automated where possible. Besides semi-automated shuttles, gravity flow racking and conveyors, an AGV was introduced to move dairy goods into the finished goods warehouse.
Toyota Material Handling was chosen because they had delivered automation solutions to other TINE plants before, but for the first time an automated reach truck was implemented.
The Autopilot from Toyota manages 1600 pallet locations in the gravity flow racking and is able to operate in other warehouse areas during the high season.
For the past two years, the Tine dairy in Tretten has been working closely with Toyota Material Handling to get the automated BT Reflex reach truck introduced in their operation.
Both Toyota’s application engineer Frode Holm and Kristian Tande, department manager for warehouse operations at Tretten, emphasise that there was a very good collaboration and a good understanding that both parties needed the necessary time to get to the finish line.
Kristian Tande is very satisfied with the AGV from Toyota, which runs from five o'clock in the morning until ten o'clock in the evening. It has a capacity of 26 pallets per hour, depending on how high it has to lift. The goods with the highest turnover speed are therefore placed in the lowest locations.
It does take longer for an AGV to retrieve and pick pallets compared to a manual truck with driver due to the narrow operating space at Tine Tretten. This reduces the truck speed to maximum 2.2 m/s and requires the necessary checks by the camera and adjustment of the fork position to ensure safe load handling – but above all, it brings a lot of benefits to Tine:
The TINE employees notice that the AGV stops once in a while, not due to a technical issue, but for example when there is a small wood chip in front of one of the sensors.
Frode Holm states that workers can quickly get the truck up and running again, by driving the truck manually (all Autopilots from Toyota can be operated manually). Even though workers are notified by the sound of the truck stopping, Kristian Tande appreciates the text message notification, which is convenient when performing other work tasks
Kristian explains that the capacity of 26 pallets per hour is sufficient on a normal production day, but during the porridge season significantly more is produced and then manual reach trucks are supporting the AGV.
Now that production has grown by around ten percent a year, Tine is considering purchasing an extra automated truck for the warehouse. This may need some space restructuring, as the warehouse was originally built for manual operation.
If they had to build a new warehouse today, they would adapt it better for automated trucks, with better quality of the floor and more space.
