Abstract

The automatic sorting of laundry items requires a knowledge of all sorting criteria. One strives to read these out from data storage media attached to the laundry items. The problem is when laundry items lack data storage media, or they are not readable because they have been damaged, for example. The invention calls for deriving sorting criteria which cannot be otherwise obtained from at least one imaging recording of an imaging device, such as a 3D-camera. Such sorting criteria, which cannot be derived from the picture or recording of the 3D-camera, are derived from supplemental information which can be obtained in different ways. Thus, it is also possible to sort laundry items without data storage medium or with damaged data storage media in a fully automatic or at least largely automatic manner.

First claim

What is claimed is:

1. A device for sorting of laundry items, preferably laundry items for cleaning, comprising:
an identification station;
a sorting station;
a transport system for transporting the laundry items hanging on the transport system through the identification station and the sorting station;
at least one imaging device & assigned to the identification station, the at least one imaging device for producing recordings of a particular laundry item;
at least one detection station provided for the acquisition of at least one supplemental piece of information to a respective one of the recordings of the particular laundry item produced by the imaging device; and
a database for criteria coming from the recordings produced by the at least one imaging device and the at least one supplemental piece of information obtained at the at least one detection station,
wherein the at least one supplemental piece of information belonging to the respective one of the recordings is deposited in the database with the respective one of the recordings.

2. The device according to claim 1 , further comprising at least one storage line, wherein the at least one detection station is assigned to the at least one storage line.

3. The device according to claim 1 , wherein the at least one supplemental piece of information belonging to the respective one of the recordings is deposited in the database with the respective recording in a common data record.

4. The device according to claim 3 , further comprising an evaluation device for the comparing of a recording currently produced by the imaging device and/or at least one criterion derived from that with recordings and/or criteria in the database.

5. The device according to claim 2 , wherein the at least one storage line is part of the transport system.

6. The device according to claim 4 , wherein the evaluation device is connected to the database.

7. A device for sorting of laundry items, comprising:
an identification station for determining whether the laundry items have a data storage medium or have a readable one of the data storage medium and, for those of the laundry items that have the data storage medium or have a readable one of the data storage medium, for reading data of the laundry items from the at least one of the data storage medium provided on the laundry items;
a sorting station;
a transport system for transporting the laundry items hanging on the transport system through the identification station and the sorting station;
at least one imaging device assigned to the identification station, wherein the at least one imaging device produces a recording of at least one of the laundry items;
at least one detection station provided for the acquisition of at least one supplemental piece of information to the recording of the at least one of the laundry items produced by the imaging device; and
a database for criteria coming from the recording produced by the at least one imaging device and the at least one supplemental piece of information obtained at the at least one detection station, wherein the at least one supplemental piece of information belonging to a particular recording is deposited in the database with the particular recording in a common data record.

8. The device according to claim 7 , further comprising at least one storage line, wherein the at least one detection station is assigned to the at least one storage line.

9. The device according to claim 8 , further comprising an evaluation device for the comparing of a recording currently produced by the imaging device and/or at least one criterion derived from that with recordings and/or criteria in the database.

10. The device according to claim 9 , wherein the at least one storage line is part of the transport system.

11. The device according to claim 10 , wherein the evaluation device is connected to the database.
