Materials Sensors
By the time a container reaches the end of the conveyor, it passes the retro-reflector materials
sensors. As shown in Figure 3-4 on page 3-6, the emitter is lined up on the left side of the Scanner
Display, and the reflector are across from the emitter on the right side of the Scanner Display. The
function of the material sensor is to determine the position of container as it enters the conveyor.
The RVM software uses this information to optimize container acceptance for speed and accuracy.
3.3.4.
PET Sensor
The PET sensor emitter is at the left side of the Scanner Display. The receiver is across from the
emitter on the right. The PET sensor works by emitting a beam of light through the container and
receiving the distorted beam on the other side. If the container is PET, the receiver recognizes its
light pattern. The RVM
uses this information for sorting and to determine acceptance or rejection.
3.3.5.
Load Cell Flex
The
Load Cell
is mounted on the Intake Chute on the
Flex
. When the container reaches
the end of the conveyor, it is weighed to assure the container is within a specified weight
range. The
RVM
uses this information for calculating mass and to determine acceptance or rejection.
3.3.6.
Load Cell Flex HDS
The LOAD CELL is mounted on the Load Cell Assembly on the FLEX HDS. When the
container reaches the end of the front conveyor, it is weighed to assure the container is
within a specified fill. The RVM
uses this information for calculating mass and to determine
acceptance or rejection.
3.3.7.
Camera/Laser
The
Camera/Laser Assembly
is mounted behind the
RVM
. As the container is being
weighed at the end of the conveyor it is also being scanned by the laser and a picture is
taken to assure it falls within the container dimensions. The
RVM
uses this information of
container dimension to determine acceptance, rejection and to prevent fraud.
