Sorting device and method for sorting RFID tags
sorting device for RFID tags, comprising a dispensing unit for supplying RFID tags which are applied to a transport belt to a dispensing area, in which the RFID tags are detached from the transport belt; a pick-up unit having a plurality of transport units for respectively picking up the RFID tags in a respective pick-up area onto a corresponding transport belt of the transport units and a positioning device for positioning the dispensing area and a selected pick-up area with respect to one another so that the RFID tags detached from the transport belt in the dispensing area are picked up by the pick-up area of the selected transport unit.
1. A sorting device for RFID tags, comprising:
a dispensing unit for supplying RFID tags which are applied to a transport belt to a dispensing area, in which the RFID tags are detached from the transport belt;
a pick-up unit having a plurality of transport units, each having a corresponding transport belt, for picking up the RFID tags in a respective pick-up area onto a corresponding transport belt of the transport unit;
a positioning device for positioning the dispensing area and a selected pick-up area with respect to one another so that the RFID tags detached from the transport belt in the dispensing area are picked up by the pick-up area of the selected transport unit;
a test device through which the transport belt runs before reaching the dispensing area configured to classify each of the RFID tags according to one parameter; and
a control device for selecting the transport unit as a function of a result of the classification.
2. The sorting device according to claim 1 , wherein the control device carries out the positioning of the positioning device as a function of the classification for a respective RFID tag in such a way that the positioning device positions the dispensing area and the pick-up area at a point in time such that the respective RFID tag is picked up by the transport belt of the selected transport unit.
3. The sorting device according to claim 1 , wherein the dispensing unit has in the dispensing area a dispensing edge which can be positioned by the positioning device.
4. The sorting device according to claim 3 , further comprising a compensation device which, as a function of the selected position of the dispensing edge, compensates a displacement of the transport belt in the dispensing area which is brought about by the positioning of the dispensing edge.
5. The sorting device according to claim 4 , wherein the compensation device comprises two dancer rolls which are coupled to one another and of which one is arranged in front of the dispensing unit and one is arranged behind the dispensing unit as seen in the transport direction of the transport belt, wherein the dancer rolls are configured to move in a direction of displacement in order to compensate the displacement of the transport belt resulting from the positioning of the dispensing edge.
6. A method for sorting RFID tags, comprising:
supplying classified RFID tags which are applied to a transport belt to a dispensing area, in which the RFID tags are detached from the transport belt;
selecting one of a plurality of transport units for picking up the RFID tags in an associated pick-up area; and
positioning the dispensing area and the selected pick-up area with respect to one another so that the RFID tags detached from the transport belt in the dispensing area are picked up by the pick-up area of the selected transport unit.
7. The method according to claim 6 , wherein the transport unit is selected as a function of the classification of the RFID tag.
8. The method according to claim 7 , wherein positioning the dispensing area and the selected pick-up area positions the dispensing area and the pick-up area at a point in time such that the respective RFID tag is picked up by the transport belt of the selected transport unit.
9. The method according to claim 6 , wherein:
positioning the dispensing area and the selected pick-up area results in a displacement of the transport belt in the dispensing area; and
the displacement of the transport belt in the dispensing area is compensated as a function of the selected position of the dispensing area.
10. A sorting device for RFID tags, comprising:
a dispensing unit for supplying RFID tags which are applied to a transport belt to a dispensing area, in which the RFID tags are detached from the transport belt;
a pick-up unit having a plurality of transport units for respectively picking up the RFID tags in a respective pick-up area onto a corresponding transport belt of the transport units;
a positioning device for positioning the dispensing area and a selected pick-up area with respect to one another so that the RFID tags detached from the transport belt in the dispensing area are picked up by the pick-up area of the selected transport unit, wherein the dispensing unit has in the dispensing area a dispensing edge which can be positioned by the positioning device; and
a compensation device which, as a function of the selected position of the dispensing edge, compensates a displacement of the transport belt in the dispensing area which is brought about by the positioning of the dispensing edge.
11. The sorting device according to claim 10 , wherein the compensation device comprises two dancer rolls which are coupled to one another and of which one is arranged in front of the dispensing unit and one is arranged behind the dispensing unit as seen in the transport direction of the transport belt, wherein the dancer rolls are configured to move in a direction of displacement in order to compensate the displacement of the transport belt resulting from the positioning of the dispensing edge.
