– Contour Measurement System

4 Functions
4.1 Operating principle
The contour measuring system CMS 700i detects of an object of any shape:
Length, width, height of the smallest enveloping cuboid
Rotation angle to transport direction
Smallest vertical distance between the object and the conveyor belt.
All objects are measured as they pass through.
System setup with 3 light curtains
Measurement start: Interruption of the first beam of the length light curtain or trigger by an optional
trigger.
Measurement stop: No beams of the width and height light curtain are interrupted.
System setup with 2 light curtains and 1 rotary encoder
Measurement start: Interruption of one beam of the height or width light curtain or trigger by an
optional trigger.
Measurement stop: No beams of width and height light curtain are interrupted.
After the measurement, the control unit (LSC-Box) automatically forwards the calculated object data to
a host via a fieldbus interface. Data from other peripheral devices such as scales or barcode readers
can also be transferred in the interface protocol. After data output, the next object can be acquired.
NOTICE
Important for valid measurement!
As long as the measurement is running, the beams of the light curtains must not be
additionally interrupted by manual interventions or other actions! This falsifies the measured
values.
Observe minimum object distance and maximum transport speed! See chapter 4.5.
