3.3.1. Scanners
The Sensor Display has two (2) scanners mounted on the top side. The two (2) scanners are wired
to a multiplexer
(
MUX
)
board that coordinates the flow of data to and from the
RVM
software, so
they are all working together as if it was one larger scanner. This scheme provides a wide scanning
range to find a container’s bar code. See Figure 3-5 on page 3-6 to see the location of the scanners.
3.3.2. Motorized Conveyor
The conveyor pulls the container into the machine. As the container travels on the conveyor, the
scanners attempt to read the bar code. If the bar code is on the bottom, the scanners cannot see it. In
this case, the conveyor returns the container and asks to turn it so the barcode is facing up. Once a
scanner finds the bar code, the accepted container is weighed and is pushed into the Sorting Cylinder
or reverse to reject the container. See Figure 3-6 for an illustration of the conveyor for the
FLEX
