SERVOMOTION · SIMULTANEOUS MULTI-LASER POSITIONING
The right solution for high-density industrial lines where several cutting lines must be positioned at the same time:

Architecture
Power transmission, carriage guidance and motion drive sit in one rail assembly. One servo axis performs all movement instead of a motor, drive and cable per laser: fewer components and a simpler maintenance routine. The number of servo axes remains unchanged as laser carriages are added, helping limit system complexity as the application scales.
Lasers are powered continuously at any position along the rail, so moving cables and energy chains are not required.
Each laser travels in its own carriage. When it reaches its position it locks on the rail and stays there independently of the shuttle.
The only moving axis of the system. It carries the carriages to their recipe positions in sequence and withdraws when finished.
Cut dimensions are entered at the panel, and the system calculates the target position for each laser.
The shuttle positions itself under the next laser carriage on the lower rail.
The carriage is moved to its recipe position with the laser on, so the reference line can be followed as it travels.
The carriage is fixed in position and becomes independent of the shuttle.
The shuttle moves to the next carriage; once all lines are set it withdraws to the home position.
No servo motor, drive or cable per laser. As the system grows only the number of carriages increases, not the parts list.
Periodic maintenance is concentrated on the single servo axis. The carriages have no moving electrical connections.
Carriages are added, removed and lasers replaced from the rail; the housing does not have to be removed from the line.
When the number of cutting lines grows, the drive and control infrastructure stays the same; only carriages are added.
Few moving components mean few spare parts and short downtime.
Motion video · Setup cycle
An uninterrupted recording of one servo axis carrying every laser carriage to its recipe position in sequence. The shuttle travels at 800 mm/s when empty and 500 mm/s when carrying a carriage; at the end of the cycle the lines settle to ±1.00 mm projection accuracy and the shuttle withdraws to its home position. The recording is an accelerated simulation of a 2,400 mm travel range with 20 laser carriages.
15 s · 1280×866 · MP4 / H.264 · Scenario: 2,400 mm travel range · 20 laser carriages · 123.2 mm line spacing · 20 active / 0 reserve · required rail 2,500 mm
Configurator
Enter the required travel range of your line and calculate the number of projected laser lines or the spacing straight away. Lasers not used by the recipe collect in the reserve zone at the end of the rail, and the tool reports carriage clearance checks, safety margins and the total rail length required in real time.
The calculation assumes equally spaced lines. Recipes with variable slice widths are also supported; in that case the limiting factor is the distance between the two closest lines.
System components
The laser carriages, the single servo shuttle and the PLC work together to bring every cutting reference to the position held in the recipe. The operator panel gives access to recipe entry and carriage status.

SAFETY
The class of the line laser module used in the system is stated on the product label and in the user manual delivered with it. Modules must be operated under the conditions defined in that manual.
The beam must not be viewed directly. Reflection angles on glossy surfaces are assessed together during installation, and the operator’s working position is reviewed at commissioning.
The system must be de-energised and the line brought to a safe state before optics cleaning and mechanical checks.
The industrial positioning laser modules used in the system have been assessed against EN 55011 and EN 55032 electromagnetic compatibility requirements and certified by TÜV Rheinland LGA Products GmbH (Cert. No. AK 50498967 0001). Request the certificate.
The declaration of conformity and the technical file for the delivered system are supplied with the delivery package, project by project.
