Interview with Pernille Lundvang, Laundry Manager at MidtVask in Aarhus
MidtVask in Aarhus, Denmark, is a publicly owned company which only cleans for the public and especially for the hospital industry.
Here, laundry manager Pernille Lundvang also sees the necessity to improve efficiency for lowering prices – and thus stay in the fight for public tenders, which are the only ones the laundry are allowed bid in on as a publicly owned company.
For the same reason, the 150 employees, which are distributed in almost 40 nationalities, are very keen about the introduction of modern technology in the company, which was named Denmark’s Best Workplace in 2018.
For example, MidtVask has invested in Inwatec’s Soiled Side-sorting-system that automates the handling of dirty garments coming into the laundry.
“We have a goal of being among Denmark’s healthiest workplaces. That is why automation and, among other things, the Soiled Side Sorting-system from Inwatec is something that really moves us in the right direction. It removes needles and removes scissors, so there is no risk of cutting. At the same time, we avoid a lot of unilateral, repeated work. So it helps to better both our competitiveness and our working environment and health,” tells laundry manager Pernille Lundvang.
“There is often someone who asks if the employees are not afraid of the strong streamlining we are doing with Inwatec. No, on the contrary. If we do not optimize all we can, we will lose our work. Automation and robotics are the only way we can be competitive and ensure that we have a workplace in the future. So from all colleagues we have a great thumbs up – that’s what we have to do,” says Pernille Lundvang, who can also see a swift ROI on the system.
“We have saved two employees compared to our old setup. So it’s a machine that has an ROI of fewer than three years. It’s excellent. At the same time, our products are made with care and care for the people who work here. It is not only to raise efficiency and to lower the prices. Our customers also really like to do business with us because they know that we focus on being a workplace with great emphasis on being diverse and because we have a good working environment,” she underlines.
As technology evolves, business opportunities arise for industrial laundries.
An example of the development is found a mere two-hour drive outside of Shanghai in the city of Nantong, where Fornet Laundry Service has a production facility for an unusual customer who runs an internet clothing rental service.
The rental company addresses private customers who can choose which clothes they want to wear in the coming days with an internet-based subscription solution. When the garments need to be washed, they are returned to the rental company, and then the customer can choose another dress, a different pair of other trousers, or something else.
To make the solution profitable and to keep the stock as low as possible, the returned items must be registered, quality assured, sorted, washed and pressed, so everything is ready for the next customer who has ordered it.
This is where Fornet Laundry Services comes into the picture, and in order to secure a fully integrated process the Fornet laundry is located in a building between two warehouses of the rental company.
Simple workstations provide high quality
Among the early investments was an Inwatec RFID sorting system that ensures that the clothes are sorted correctly before washing.
“It is a fascinating challenge when we have to handle so many different types of clothes. We have over 30,000 different garments in the database, and we have them mapped with different sorting logic, so we separate items for dry cleaning and get the right colors and textile types in the right washing machines,” explains Lei Pai, Manager at Fornet.
In the unpacking area, the operator unpacks the returned parcel, checks for defects and wear, scans the barcode to update the system, and then attaches the RFID chip with a rubber band. The chip and barcode are then paired in the system database and that way all relevant data on the individual piece of clothing is preserved and processed correctly.
Fornet is using HF-RFID chips, as it is the most suitable in terms of workstations spacing to avoid reading the wrong chip as it could happen with UHF.
“The customer has focused on keeping the workstations as ergonomic as possible, and also the HF-RFID solution made it economically viable to put scanners up at all tables in the unpacking department. That way everything is checked, scanned and marked correctly when the units are put on the conveyor belt that leads to the sorting for further processing, and we can maintain high production capacity without sacrificing quality,” Lei Pai states further.
Manual handling with an automatic twist
The initial quality control is carried out by employees, who will, among other things, handle damaged garments. There are no plans to do alternate that part of the setup, but when it comes to the rest of the process, Fornet will automate as much as possible.
“Sorting is very labour intensive, so it’s a big win that we can handle it automatically. We have 13 bins with static sorting to ensure that the same type of garments ends in the same place. If we move the positions we risk more human errors,” says Lei Pai, who in early September had a trouble-free grand opening of the laundry with a lot of interested guests.
“We have launched production with an existing inventory, where all garments were not mapped optimally in relation to how it should be washed. However, we are well prepared to adjust that on the run and with all the new garments that come in, we know how to get all parameters correctly set up, and our logic in the sorting can also be optimised accordingly,” Lei Pai tells.
Good service and openness
Fornet Laundry Services operates several laundries around China, and since the company previously purchased a larger Inwatec system with x-ray and RFID sorting to a department in Shanghai, there was no hesitation in sending a new order to Denmark when the project in Nantong was to be implemented:
“We were in Denmark to see a system in a hospital, and we realised that it was a great idea for the laundry in Shanghai. The solution has worked as we wanted, and we also had an excellent dialogue about this project too,” says Lei Pai, stressing that the distance from Nantong to Inwatec in Odense is irrelevant.
“When we need support for the technology or software, it’s always on time, and we were completely confident in choosing Inwatec again. There was no doubt,” says Lei Pai.
