PackTrack™
PackTrack is a patented operating mode for Datalogic Omni-Directional Reading
Stations used to read and correctly assign codes read on different packs when
placed in the scanner Reading Area at the same time.
In fact, in the following example, the codes of two or more consecutive packs are
found at the same time in the scanner reading area. Therefore, the condition
occurs where, in the sequence of the two packs, the code of the second pack is
read first, just before the code of the previous pack. A system without PackTrack
would assign the code of the second pack to the first pack and vice versa, thus
causing a gross error in sortation.
PackTrack uses a right-handed reference system where the X axis coincides with
the Photoelectric Sensor line, the Y axis coincides with the conveyor direction,
and the Z axis is oriented upwards from the conveyor (see figure below). The
arrows point in the positive direction. The coordinate point of origin (0,0,0) is on
the left edge of the conveyor as illustrated.
Tracking starts 10 cm before and stops 10 cm after the Reading Area
in order
to ensure the barcode is assigned to the correct package.
