Lights-out picking at Finland’s largest dairy
Valio – nowadays the largest dairy products company in Finland – was established in 1905 to help boost the export of Finnish butter. At that time no one would have believed that in the space of 100 years of operation, 200 million kg of products would be order picked by robot. Currently the Valio product portfolio includes about 750 chilled products, a third of which are picked using the Cimcorp MultiPick robot system. Besides the robots, the WCS system in particular has received a lot of praise, as it enables the monitoring of real-time operations in all the warehouses, including those where order picking is still largely carried out manually
Finland is one of the major consumers of milk in the world. According to the statistics, annual consumption of milk is just less than 140 liters per capita – 86 percent of which is produced by Valio. When you add the hundreds of other dairy items to the different milk products, the production volumes are staggering: annually Valio delivers 750 million kilograms of products to its customers. In terms of order lines, that is about 45 million lines a year.
As far as fresh foods are concerned, accuracy and speed of delivery are naturally of top priority. Demands for efficiency in Valio’s order picking and dispatch operations have been addressed in part by automating both warehousing and order picking.
About 450 million kg of products go through the main warehouses in Riihimäki and Jyväskylä.
“About half of the volumes picked in the main warehouses are picked by Cimcorp gantry robots. Automation plays a significant role in both warehousing and dispatch operations, as about 60% of all our products are picked in these warehouses,” says Heli Helminen, warehouse operations manager at Valio. No labor is required for the volumes picked by the Cimcorp gantry robots other than to roll finished orders onto trucks.
As well as the robots, Helminen has special praise for Cimcorp’s WCS (warehouse control software), which has enabled real-time monitoring and reporting of warehouse operations.
“We also use Cimcorp’s warehouse control software alongside SAP in Tampere and Oulu, where products are picked manually. The WCS provides us with the necessary transparency, and monitoring of operations can also be done between the various warehouses. In our view, this is one of Cimcorp’s real selling points,” says Helminen.
Apart from the direct effects of the Cimcorp WCS system, Valio has also enjoyed some indirect benefits. When the company implemented voice-directed picking at the Oulu site in 2007, one of the preconditions was setting up warehouse control software.
“There are over 100 order pickers on the payroll at our Oulu warehouse, whose work used to be based on printed lists. Now the lists have been replaced with headsets and their hands are free. Thanks to the voice-directed system many traditional work stages can be bypassed, and thereby we have increased the efficiency and accuracy of our operations.”
From minimum to maximum
As well as the key benefit of cost efficiency, Helminen believes that the Cimcorp automation systems have also achieved other important results. Order picking errors have been minimized, and the effective throughput, storage, and picking of large volumes have been facilitated.
“The robot systems have enabled an efficient and rapid flow for high volume products. In other words we can get products very quickly from production to the stores. In the best case scenario, milk can move from the packing section to the consumer’s refrigerator within six hours!” says Helminen.
And since the products move so quickly from production to stores, monitoring also has to be kept continually up to speed.
“In dairies that make fresh products, the timeliest packing possible according to actual demand is an essential factor in practical terms. These challenges have been answered by adding the pull control application to the WCS. This allows us to monitor customer orders and production volumes minute by minute.”
Although the situation in relation to efficient use of time is now looking good, Helminen thinks that the demands of the supply chain will grow even more in the future. As product ranges expand and the markets grow, operators in the sector will be expected to manage their business on an even larger scale.
“We have continuous cooperation with Cimcorp, in particular regarding software development. The results have been impressive and I believe that we will continue to see more positive improvements in the future,” smiles Helminen.
