Abstract

Bei der Behandlung von Wäschestücke (10) in Wäschereien kommt es vor, dass die angelieferte Schmutzwäsche Fremdkörper aufweisen. Damit die Wäschestücke (10) während der Behandlung nicht beschädigt werden, müssen die einzelnen Wäschestücke (10) vor der Behandlung händisch auf Fremdkörper inspiziert werden. Das ist sehr zeitaufwendig und somit teuer. Außerdem gilt es zu vermeiden, dass sich bei der Behandlung der Wäschestücke (10) nasse bzw. feuchte Stellen bilden. Die Erfindung schafft ein Verfahren und eine Vorrichtung, mit der Wäschestücke (10) auf eine günstige und zuverlässige Weise inspizierbar sind. Dazu ist es vorgesehen, dass die Wäschestücke (10) mit Terahertz-Strahlung (11) beaufschlagt werden, um zu prüfen, ob die Wäschestücke (10) Fremdkörper und/oder nasse bzw. feuchte Stellen aufweisen.

Figure imgaf001
In the treatment of laundry items (10) in laundries, it can happen that the delivered dirty laundry has foreign bodies. So that the items of laundry (10) are not damaged during the treatment, the individual items of laundry (10) must be manually inspected for foreign bodies before treatment. This is very time consuming and therefore expensive. In addition, it should be avoided that wet or damp spots form during the treatment of the items of laundry (10). The invention provides a method and a device with which items of laundry (10) can be inspected in a favorable and reliable manner. For this purpose, it is provided that the laundry items (10) are exposed to terahertz radiation (11) in order to check whether the items of laundry (10) have foreign bodies and / or wet or moist areas.
