Measuring the volume
The volume measurement is carried out if a valid bar code or stable weight value is
available.
To do so, the light grids mounted on the measurement gantry are manually moved over
the measurement object using the two linear guides. Measurements can be taken in both
directions, stopped whilst doing so, and then recommenced.
If the monitoring field is interrupted by an object, the shadowing and the resulting number
of interrupted light beams on the receiver lines can be used to detect the profile of the
object.
The change in the number of beams on the receiver lines as a result of the shadowing is
transmitted via the light grids’ interfaces to the MSC800 as a digital signal.
Two-dimensional cross sections are created by moving the light grids across the object.
The controller then combines the individual 2D cross sections of the object.
Fig. 17: Operating principle – volume measurement
By taking into consideration the speed with which the measurement gantry is moved
across the object and the respective position of the light grids above the object, a spatial
image is produced which is used to calculate the smallest possible cuboid which could
surround the object as well as its volume.
