All system components are mounted on a frame provided by the customer according to
the technical drawing. The volume measurement devices are mounted using a mounting
system included in the scope of delivery, which is attached to the frame.
Additional glare protection on the frame (beam blocker) prevents objects located outside
of the measuring range from being taken into account when calculating the measured
values.
The figures in these operating instructions show the mounting set consisting of a width-
adjustable telescopic tube with pre-mounted attachment mechanism for the volume
measurement devices and for mounting to a frame provided by the customer.

The VMS4200 / VMS5200 volume measurement system consists of two LMS4xxx volume
measurement devices, which are mounted on the left and right above the conveying
equipment. The volume measurement devices configured as master and slave scan the
object and transmit the detected measuring points to the SIM2000 control unit.

Modular mounting set
The officially verifiable VMS5200 volume measurement system also has a separate LFT
display to show the measurement results, status information, the firmware version, and
the logbook (version history).
The measuring wheel encoder mounted below the conveyor belt is needed for position
determination of the object on the conveyor belt and for the calculation of the 3D model.
As part of this process, the encoder sends two incremental signals to the controller –
there is a 90-degree phase shift between the signals.
Measurement is performed directly on the running surface of the conveyor belt using a
precise measuring wheel, which is mounted on a spring-loaded arm.

3.2.2 Expanding the system with a reading station
The VMS4200 / VMS5200 volume measurement system can be expanded to include a
reading station. The reading station allows automated identification of objects by reading
their bar codes, which in turn enables faster process automation. Depending on the
application case, this station can consist of scanners, cameras and/or a combination of
both in any desired arrangement.
The devices are connected to the volume measurement system via the CAN bus of the
SIM2000 controller. The controller links the acquired identification data with the
dimensional values calculated by the VMS4200 / VMS5200 and outputs both data types
to the higher-level system.

The VMS4200 / VMS5200 volume measurement system measures cubic and irregularly
shaped objects that are moved past the measuring station on flat conveying systems.
3.3.1 Operating modes
The volume measurement system can either be in free-running or triggered operating
mode.
In free-running mode, the volume measurement system detects the objects to be
measured itself. The measurement starts when an object enters the scanning line of the
volume measurement devices. It ends when the object leaves the scanning line.
Fig. 9: Free-running operating mode
In triggered mode, the object is detected via a trigger signal, not automatically. The trigger
signal can be triggered by the entry of the object into the path of a photoelectric retro-
reflective sensor or via a customer-controlled digital signal.
The trigger signal activates the volume measurement devices and opens the internal
reading gate. The reading gate determines the start and the end of the measuring
process. It corresponds to the trigger length in the conveying direction. The measuring
process lasts for as long as the reading gate is open, regardless of whether the object is
entering the scanning line or leaving it.

Object detection via a trigger signal also reliably detects very flat objects.

In both operating modes, the incremental encoder supplies information to the conveying
equipment for exact position definition of the object. This information is required to
calculate the length information and for correct assignment of the measurement results
to the object.
The supplying conveying equipment must pass on the objects to the volume
measurement system separately and at the minimum distance of 50 mm, which is
required for error-free processing. The objects may be placed on the conveyor belt in any
direction.

Objects that are touching or lying side-by-side cannot be measured using the volume
measurement system. The system does not give plausible measurement results in this
case.

3.3.2 Calculating the volume
The calculation of measurement values begins as soon as an object is transported past
the volume measurement devices on the equipment below. The volume measurement
devices span a two-dimensional measuring range and scan the surfaces of the object
located within this range on the conveying equipment, without making contact. The
volume measurement device measures its surroundings in two-dimensional polar
coordinates, relative to its measurement origin. This is marked by a circular indentation
on the upper side of the housing.
The VMS4200 / VMA5200 is an active system featuring a laser in the visible range (red).
It does not require position marks, reflectors, or object illumination.
If a laser beam strikes an object, the position of that object is determined in terms of
distance and angle. This functions according to the principle of phase shift (continuous
wave). There is a phase difference between the transmitter and receiver beams resulting
from the run time of the light and the wavelength used. This phase difference is used to
calculate the distance of the object from the zero point.
Fig. 13: Functioning of the volume measurement device
The measuring points determined by the two volume measurement devices are cyclically
transmitted to the SIM2000 controller.

Using the established speed of the conveyor element and the specific position of the
object on the belt, the controller creates a spatial model from which the smallest
rectangular box that fully encloses the object is determined and the values for volume,
length, width and height are calculated. The measurement results of the officially verified
volume measurement system are shown on a separate LFT display.
Fig. 15: Volume calculation in the SIM2000
If the VMS4200 / VMS5200 volume measurement system is working in a complete
system with a reading station, the contour data can be used as the basis for the dynamic
camera focusing. For this purpose, the controller supplies continuous information about
the distance of the measurement sensor to the object surface via the CAN bus.

3.3.3 Data processing and data output
The SIM2000 is the volume measurement system’s central control unit. All the volume
measurement system information is processed here. It assumes the measuring points
from the volume measurement devices and uses this to generate a three-dimensional
model. It processes the signals from the measuring wheel encoder and (optionally from
the photoelectric retro-reflective sensor).
It calculates the volume and uses this to determine the length, width, and height. It
assigns the measurement results to the object and outputs them to the higher-level
system via a host telegram coordinated by the customer.
The calculated 3D point cloud of the calculated model can be optionally output here.
Fig. 17: Data output (host telegram)
In the case of an officially verifiable VMS5200, the measurement results are saved in the
SIM2000 alibi memory, which is required for verification, prior to output. The
measurement results are also displayed on the LFT display.

irregularly shaped measuring objects.
The different nominal operating conditions are described below depending on the object
size.
3.4.1 Fixed scale values
If the plant is operated without scale value switchover, the measuring range and scale
interval are fixed throughout the entire system depending on the application, and are
therefore the same for all measured objects.

3.4.2 Dynamic scale value switchover
In the case of dynamic scale value switchover, the scale interval can be changed depending
on the relevant measured object dimension, i.e., length, width, or height.
The defined scale intervals need to be documented on the information label. It is only
permitted to select scale intervals based on the scale values from section 3.4.1 Fixed scale
values.
The measurement accuracy switchover can take place from object to object. The switchover
point is set during commissioning and cannot be changed when the calibration switch is
activated and locked (for information on the calibration switch, see chapter 3.6.3 SD card
with alibi memory).
In the following example, the volume measurement system is working with the two scale
intervals 5 mm x 5 mm x 5 mm (scale values for operating condition 2) and 10 mm x
5 mm x 5 mm (scale values for operating condition 3). An object length of 2,000 mm has
been defined as the switchover point during commissioning.
Objects with a length less than or equal to 2,000 mm are measured under operating
condition 2 with the scale values 5 mm x 5 mm x 5 mm.
For objects with a length greater than 2,000 mm, the volume measurement system
automatically uses the scale values 10 mm x 5 mm x 5 mm due to the detected object
length.
Fig. 20: Dynamic scale value switchover
In the case of dynamic scale value switchover, the relevant scale values (see the tables
above) used by the VMS5200 are also displayed on the LFT display together with the
measurement result.
