Towel feeding robot by Inwatec


We have now started development of a fully automated towel feeding robot. Building on the excellent work done by JENSEN. First robot prototype with use of artificial intelligence expected in 2018.

Feeding towels are hard and repetitive work. JENSEN has made a significant development work to automate this job with the JENSEN Evolution Cube. Inwatec will now add the newest robot technology and artificial intelligence to the solution, to make it more robust. This project moves the partnership between the JENSEN-GROUP and Inwatec to the next level.

“We are busy building the future in laundry automation. From day one it has been the idea that the engineers of Inwatec together with the engineering departments within JENSEN shall develop new solutions and services to automate all processes in heavy-duty laundries. We are sure that our next edition of the Evolution Cube will be a real game-changer that proves it,” says JENSEN-GROUP CEO Jesper Jensen.

“I see almost daily our LaundryNerds playing with towels, to see how we can find the corners, and feed the towels robust to a folding machine. There is no doubt that we need speedy robots, and 2D and 3D computer vision to solve this challenge. We see a breakthrough in using artificial intelligence in our machines today, with improved performance and reliability,” says Inwatec CEO Mads Andresen.

“Our Robot Separator is working better and better. We made the first prototype two years ago, and we have already five robots working every day in laundries. It has been a real challenge, and we thought that it was just a matter of finding the optimal pick point, and then grasp with an ordinary robot gripper. We could only achieve 60-70% success rate with this method! But even worse, too many double picks (5-10%). We also got the feedback from laundries, that traditional grippers destroy too many garments. The result was too low throughput. We realised that we had to develop a new gripper. We have been working on this since January, and the most recent test has shown pick rates of 97-99%, with way less double picks. We can’t wait to upgrade our existing robots with this new tool. We also have a pending patent on this new method, that is also more gentle to the textile.” says Mads Andresen.

“We will continue with our learnings from that process, and we have some pretty good ideas of how to develop a fast and reliable fully automated system that both separates and feeds. Towels come in all kinds of sizes and fabrics, and obviously, it isn’t a straightforward job to feed the folding machines, but the JENSEN team have got much experience also, and I think we are a long way down the road. So much I dare promise that the first prototypes will be assembled in our workshop in 2018,”

Inwatec’s firsts move into the laundries happened with the X-Ray Sorting System, and later a Robot Separator to further automatize the handling of the soiled textiles. More recently Inwatec has also produced a Stack Storage System for clean linen, and Mads Andresen reveals that Inwatec has many more innovations in the pipeline.

“Our motto has always been “We remove the dirty work”, and this is the first time we really remove the dirty work together with JENSEN,” says Mads Andresen.
