System for locating and identifying at least two separate items

摘要

A system for locating and identifying at least two separate items, for example packaging, includes a capacitive first sensor detecting a first measuring region at a first position of a sensor device, for example a sensor film on a shelf bottom for packaging, a capacitive second sensor detecting a second measuring region at a second position, differing from the first position, of the sensor device, an electrically conductive first mark of a first item in the measuring region of one sensor, an electrically conductive second mark of a second item in the measuring region of the other sensor, and an evaluation device evaluating signals from the sensors, the signals caused or changed by electrical conductivity of the marks. Items can be capacitively detected and information obtained can be used to improve warehousing. The sensors and the marks can be produced quickly and cost-effectively by printing processes or film transfer.

1. A system for locating and identifying at least two separate items, the system comprising:
a sensor device having a first position with a first measuring region and a second position with a second measuring region, said second position differing from said first position; at least one capacitive first sensor configured to detect said first measuring region at said first position of said sensor device, said at least one capacitive first sensor being at least one electrically conductive area including printable, electrically conductive material; at least one capacitive second sensor configured to detect said second measuring region at said second position of said sensor device, said at least one capacitive second sensor being at least one electrically conductive area including printable, electrically conductive material; at least one electrically conductive first mark of a first item disposed in said measuring region of one of said sensors, said at least one electrically conductive first mark being at least one electrically conductive area including printable, electrically conductive material; at least one electrically conductive second mark of a second item disposed in said measuring region of another of said sensors, said at least one electrically conductive second mark being at least one electrically conductive area including printable, electrically conductive material; and an evaluation device configured to evaluate signals from said sensors, the signals being caused or changed by electrical conductivity of said marks of the items.
