Abstract

An automated checkout system and method including a conveyor system that automatically transports objects along an item path through a read zone of a data reader (such as a portal data reader, tunnel scanner or other type of automated reader) and to an exit zone, an indicator system disposed in or along the exit zone that provides indication as to whether an item has been identified by the portal data reader. In one example, the indicator system includes lights at an indicator location that are selectively alighted a given color for the duration of the item passing the indicator location depending upon whether the reader successfully read the item (e.g., color green) or unsuccessfully read the item (e.g., color red).

First claim

The invention claimed is:

1. An automated checkout system, comprising
a data reader having a read zone, the data reader being operable to identify items being transported through the read zone;
a conveyor system having an input zone and an exit zone, the conveyor system configured to automatically transport the items from the input zone, through the read zone of the data reader, and to the exit zone;
a lighting indicator system disposed at an indicator location proximate the exit zone of the conveyor system, the lighting indicator system turning on upon the item reaching or entering the indicator location, wherein the lighting indicator system comprises a series of lights arranged along a side rail proximate the exit zone and alights a given color in response to input from the data reader,
wherein the lighting indicator system is operative to turn on and alight continuously upon a leading portion of the item reaching the indicator location.

2. A system according to claim 1 wherein the data reader includes an optical code reading system operable for reading optical codes on the items for identifying the items transported through the read zone.

3. A system according to claim 1 wherein the data reader includes an optical recognition system operable for using optical recognition to identify the items being transported through the read zone.

4. A system according to claim 1 wherein the data reader comprises a portal data reader unit including one or more arch sections disposed over a portion of the conveyor system and defining the read zone.

5. A system according to claim 1 further comprising a controller operative (a) to generate a first signal corresponding to a successful identification of an item transported through the read zone and (b) to generate a second signal corresponding to an unsuccessful identification of the item transported through the read zone,
wherein in response to the first signal, the lighting indicator alights a first color corresponding to the successful identification,
wherein in response to the second signal, the lighting indicator alights a second color corresponding to the unsuccessful identification.

6. A system according to claim 5 wherein the first color is green and the second color is red.

7. A system according to claim 1 further comprising an imaging system and a display monitor, wherein the imaging system is operative for acquiring an image of the item for sending to the display monitor.

8. A system according to claim 1 wherein the lighting indicator system comprises a lighting source disposed over the conveyor and operative to project a light beam or curtain down onto the item at the indicator location thereby alighting at least a portion of the item with a light of the given color.

9. An automated checkout system, comprising
a data reader having a read zone, the data reader being operable to identify items being transported through the read zone;
a conveyor system having an input zone and an exit zone, the conveyor system configured to automatically transport the items from the input zone, through the read zone of the data reader, and to the exit zone;
a lighting indicator system disposed at an indicator location proximate the exit zone of the conveyor system, the lighting indicator system turning on upon the item reaching or entering the indicator location, wherein the lighting indicator system alights a given color in response to input from the data reader,
wherein the lighting indicator system is operative to turn on upon a leading portion of the item reaching the indicator location and then turn off upon a trailing portion of the item reaching the indicator location.

10. An automated checkout system, comprising
a data reader having a read zone, the data reader being operable to identify items being transported through the read zone;
a conveyor system having an input zone and an exit zone, the conveyor system configured to automatically transport the items from the input zone, through the read zone of the data reader, and to the exit zone;
a lighting indicator system disposed at an indicator location proximate the exit zone of the conveyor system, the lighting indicator system turning on upon the item reaching or entering the indicator location,
wherein the lighting indicator system comprises indicator lights disposed in or on side rails at opposite sides of the conveyor system in the exit zone and alights a given color in response to input from the data reader.

11. A system according to claim 10 wherein the indicator lights are disposed on posts extending up from the side rails.

12. A method of operation for automated checkout system, comprising the steps of
transporting, via a conveyor system, items along an item path through a read zone of a data reader and to an exit zone;
via a tracking system, tracking a first item as the first item is moved along the item path;
via the data reader, attempting to identify the first item by reading an optical code on the first item as the first item is transported through the read zone; and
alighting an indicator light disposed at an indicator location in the exit zone of the conveyor system, the indicator light alighting upon the first item reaching or entering the indicator location, wherein the indicator light is from a series of lights arranged along a side rail proximate the exit zone, wherein the indicator light alights continuously upon the leading portion of the item reaching the indicator location.

13. A method according to claim 12 wherein the indicator light alights a given color corresponding to input from the data reader.

14. A method according to claim 12 further comprising
alighting the indicator light a given first color if the data reader successfully identifies the first item;
alighting the indicator light a given second color if the data reader fails to identify the first item.

15. A method according to claim 12 further comprising
generating a first signal corresponding to a successful identification of the first item having passed through the read zone;
generating a second signal corresponding to an unsuccessful identification of the first item having passed through the read zone;
in response to the first signal the lighting indicator alights a first color corresponding to a successful read;
in response to the second signal the lighting indicator alights a second color corresponding to an unsuccessful read.

16. A method according to claim 12 further comprising determining an exception to item identification if the data reader fails to identify the first item.

17. A method according to claim 16 wherein the step of determining an exception to item identification includes attempting to identify the first item with the data reader by reading an optical code on the first item.

18. A method according to claim 16 wherein the step of determining an exception to item identification further includes attempting to identify the first item with the data reader by using optical recognition to identify the first item.

19. A method according to claim 12 further comprising
via the tracking system, tracking a second item as the second item is transported adjacent to the first item and along the item path;
via the data reader, attempting to identify the second item being transported through the read zone;
alighting a second indicator light disposed at an indicator location in the exit zone of the conveyor system, the indicator light alighting once the second item reaches the indicator location.
