Fully automatic sorting of Soiled Workwear

Inwatec's sorting lines are build to fulfill each customers' needs. Thanks to modular design, the single machines can be added to a whole system according to specific wishes. In this case, the requested line consists of a Robot Separator, an X-ray machine and a vision based sorting system. 

The robot is fed by a conveyor and performs a separation of the garments. These separated garments are directly transferred to the X-ray machine, which detects foreign items like pens and scissors in the garment and automatically rejects these clothing items.

Accepted garments are forwarded to a vision based sorting, which, in this special case, sorts into either bright or dark.

The system's main components:

The Robot Separator has a high efficiency in separating textiles. It works fully automatic and therefore reduces the risk of cuts and needle injuries for your staff. We use modern 3D cameras and advanced software to find the best gripping points on the garments. 

All details about the Robot Separator. 

Inwatec's X-ray machine automatically detects foreign items such as pens, needles, lipsticks and more. It can handle up to 2,200 items per hour and rejects garments which contain foreign items. These rejected garments are forwarded to a special bin, where the detected foreign items can be removed from the garment's pockets.

Separates more than 1,500 garments per hour: Inwatec’s Robot Separator

Inwatec’s Robot Separator has been under development since mid of 2015. In June 2015, we started with the idea of creating a robot that automatically separates garment to load it into our X-ray and sorting systems individually. While developing the robot over the past years, we especially had to overcome issues such as the relatively low speed of traditional robot arms and determining the best gripping points of modifiable objects like garments.

End of March 2017, we finally delivered the first Robot Separator to a Norwegian laundry. This first project was a development project, which we performed together. The robot can handle all kinds of garments such as white wear, linen, mops, rags, and more.

Even though we already presented a fully functioning machine, we did not stop working and improving on the speed, accuracy, and therefore efficiency of our Robot Separator. Over the past months, we have made several additional tests, adjustments, and changes to be now presenting a smooth working, fast, and precise Robot Separator for laundries. Our own delta robot system, together with 3D-cameras detecting the garment and determine the best picking-points for the textiles, now make it possible to deliver about 1500 separated pieces an hour. This throughput is comparable to most human operators and fits nicely into the flow of many setups.

We recently installed our second robot in Switzerland and are currently building number three and four.

“I think we’ve made a good progress but we are still aiming for a higher throughput. It’s a long process to develop such a system from scratch but we are confident that now we have a system that really does the job,” explains Martin, one of the responsible software engineers for the development of the Robot Separator.
