Abstract

A device for processing items, in particular items in a production sequence, in different processing steps, has at least one sensor arrangement having a plurality of sensors, wherein at least one item is measured in a detection mode by at least a partial quantity of the sensors as the detection means, wherein an impacting of the at least one item with an irradiation means is determined by a control means while considering a result of the measuring procedure of the at least one item; and wherein the at least one item is irradiated in an irradiation mode by at least a further partial quantity of the plurality of sensors as the irradiation means. If appropriate, at least part of the method is repeated with a renewed measuring, determination and/or irradiation.

First claim

The invention claimed is:

1. A method for processing items, the method comprising:
measuring at least one item using a partial quantity of sensors associated with at least one sensor arrangement having a plurality of sensors;
determining, by a control means, the impacting of the at least one item with an irradiation means while considering a result of the measuring procedure of the at least one item; and
irradiating the at least one item by at least a further partial quantity of the plurality of sensors as the irradiation means in an irradiation mode; and
if appropriate, repeating at least part of the method.

2. The method of claim 1 , wherein before the at least one item is measured, a calibration measurement is made, in which the sensors which are used, are in the detection mode.

3. The method of claim 2 , wherein in the calibration method all the sensors are in the detection mode.

4. The method of claim 1 , wherein the sensors of the arrangement are connected or activated differently such that at least a partial quantity of sensors is operated as the detector means in a detector mode and at least a partial quantity of the sensors is operated as the irradiation means in the irradiation mode.

5. The method of claim 1 , wherein the operating modes of the respective partial quantities of sensors change after a predeterminable or predetermined period of time.

6. The method of claim 1 , wherein the partial quantities of sensors of the respective mode form a pattern.

7. The method of claim 6 , wherein the partial quantities of sensors of the respective mode form a regular pattern.

8. The method of claim 1 , wherein disjoint partial quantities of sensors are operated simultaneously as the detector means and as the irradiation means.

9. The method of claim 1 , wherein an irradiation, to be carried out, of the item with sensors in an irradiation mode is determined by an iterative process, during the steps of which an intensity variable of the irradiation treatment is repeatedly measured by at least a partial quantity of sensors in the detection mode and is changed by the control means.

10. The method of claim 1 , wherein an irradiation, to be carried out, of the item with sensors in an irradiation mode is determined by an iterative process, during the steps of which an intensity variable of the irradiation treatment by sensors in an irradiation mode is calculated analytically and fixed by the control means.

11. The method of claim 1 , wherein at least a partial quantity of sensors is activated by the control means such that the surface, to be irradiated, of the item is impacted with a radiation intensity which is uniform over the surface.

12. The method of claim 1 , wherein profiled, non-planar structures of the item are also detected in the measuring procedure by at least one of different arrangement patterns of the sensor arrangement and relative positions of the detection means and of the item to be measured, and are then irradiated, if appropriate, after a corresponding calculation.

13. A device for processing items, comprising a detection means including
at least one sensor arrangement with a plurality of sensors,
wherein at least a partial quantity of the sensors is configured to measure at least one item in a detection mode;
wherein a control means is configured to determine an impacting of the item by an irradiation means, while considering a result of the measuring procedure of the at least one item, and
wherein at least a further partial quantity of the plurality of sensors is configured to irradiate the at least one item as the irradiation means in an irradiation mode.

14. The device of claim 13 , wherein the sensors of the sensor arrangement are each formed by a light-emitting diode.

15. The device of claim 13 , wherein the each of the sensors of the sensor arrangement can be respectively controlled at least in respect of the radiation intensity thereof, wherein the sensors of the sensor arrangement are formed by diodes of different colours.

16. The device of claim 13 , wherein the sensors of the sensor arrangement are formed by diodes of different colours and/or wherein the different colours of the sensors cover a wavelength range of a few 100 nm.

17. The device of claim 13 , wherein the sensors of the sensor arrangement can be activated or are activated combined severally together and/or combined into groups, and/or wherein the sensor arrangement of sensors forms at least one array of sensors.

18. The device of claim 17 , wherein the array with individual sensors, with partial quantities of sensors or collectively has a regular arrangement with respect to a surface to be irradiated.

19. The device of claim 13 , wherein the at least one item and the arrangement of the plurality of sensors are provided such that they are movable relative to one another by at least one adjusting means.

20. The device of claim 13 , wherein the at least one item and at least a partial quantity of sensors of the sensor arrangement form mutually parallel surface portions in the position of use.
