3.2 Structure of the volume measurement system

3.2.1 System components

The VMS4200 / VMS5200 volume measurement system consists of two LMS4xxx volume

measurement devices, an LFT display, a measuring wheel encoder, and a cabinet

containing the SIM2000 control unit.

Systems for which measuring is triggered via a signal also have a photoelectric retro-

reflective sensor as an accessory.

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.

Fig.8: Expanding the system with a reading station

The volume measurement system can also supply the focus information for the connected

camera systems.

3.3 Operating principle of the volume measurement 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.

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.
