Laser Jailer: The Active Laser Guarding System with Inherent Fail Safe Technology

The Lasermet Laser Jailer active laser guarding system combines an inherently fail-safe laser detection technique and Lasermet's proven laser interlock control system technology to create an active laser guarding system which is fail safe to Machinery Directive Standard EN13849-1.

Laser Jailer

This photograph shows three enclosures housing a 16kW fibre laser which is distributed to three robots - one in each separate room within the enclosure. ICS-15XM Laser interlock controllers can be seen adjacent to the doors.

Overview 

The system is designed to contain a high powered laser beam in a laser enclosure which is smaller and lighter than would otherwise be necessary. It comprises of an outer passive enclosure and an inner active enclosure made up of detector tiles which are connected to Lasermet's ICS interlock system.

Lasermet's fail-safe technology isolates the laser safety input in less than 50ms. The laser machine responds to this laser termination signal and laser radiation is terminated – the actual laser termination time being dependent on the laser machine in use.

 Laser Jailer

  • Active and Passive Laser Enclosures
  • Lightweight modular, scalable design - - saving life, preventing injury, - preventing damage to infrastructure
  • Retrofit to existing rooms/enclosures
  • Rapid turnkey solution using proven design
  • Conforms to laser safety standards EN/IEC 60825-4
  • Active Laser Guard System US Patent Applied for: 13/293,013
  • European Patent applied for: EP11188501.8
  • Australian Patent applied for: 2012202599
  • Virtually any size of active laser enclosure can be accommodated from small enclosures to full, room-size laser shelters containing robot welding machines. The fully commissioned laser cabin will then act as an effective laser barrier and beam stopper to confine the laser beam within the laser protective cabin.

Active laser guarding tiles have been fitted to the walls and ceiling of the laser safety enclosure. Here a Kuka robot fitted with a 16kW IPG fiber laser head can be seen, with the fume extraction and smoke evacuation pipework also in the photograph.

Description of the Active Laser Safety System

The active laser guard – Laser Jailer - comprises of a laser safety enclosure which is lined throughout with laser beam detector tiles. These panels, which also act as a laser shield, are connected to the Lasermet active safety control system, the laser safety interlock controller, so that if a stray laser beam impacts on one of the tiles, the interlock will isolate the laser safety input in less than 50ms. A laser warning sign on the front of the laser cabin shows if the laser is on or off. Laser Arming and Emergency Stop buttons are also installed on custom laser enclosure door.

Remote monitoring of active laser guarding systems

This schematic shows how the active safety system can be integrated with the ICS-15XM interlock system which can have the option of being monitored via the internet.

Ordering information

To specify the Active Laser Guarding System you require, the following items must be addressed.

  • Specification of the laser
  • The intended use of the laser
  • The dimensions and specification of the laser safety enclosure A large laser enclosure may need estimated measurements for quotation purposes
  • Identification of relevant safety interlocks -doors, switches, maglocks.
