PNOZmulti: Automation for the zero joint

HOMAG edge banding machine KAL 370

The visible glue joint in furniture may soon be a thing of the past: A LaserTec procedure developed by HOMAG welds edges and panel material without leaving a visible joint.

For edge processing in its machines for the furniture industry, HOMAG relies, among other things, on the use of high-power laser - and therefore also on the freely configurable safety system PNOZmulti from Pilz. HOMAG thus prevents hazards in the workplace of the machine operator.

Efficient safety management makes lasers safe

The HOMAG edge banding machine KAL 370 profiLine uses a diode laser to apply the various edges. High-power lasers with a performance of up to 2.5 kW to approx. 4 kW are potentially extremely dangerous: Any contact with the skin or the eye would lead to serious injuries or even death.

PNOZmulti from Pilz therefore ensures integrated safety management for the KAL 370: When the protective hood is opened deliberately or accidentally, the safety gate monitoring function with the electromagnetic process guarding system PSENslock from Pilz triggers immediate safe shutdown of the laser. In addition to the emergency stop pushbuttons, PNOZmulti monitors the correct start position of the laser and the presence of a workpiece. Simultaneously, the safety system monitors the current flow at the laser and the installed blowing nozzle for smoke and fire.

Efficient safety management makes lasers safe

The benefits at a glance:

  • PNOZmulti: Independent and feedback-free safety system: PNOZmulti from Pilz ensures the integrated safety management at HOMAG
  • Maximum manipulation protection (coding) and process protection via magnetic guard locking: Opening the protective hood trigger safe gate monitoring and immediate safe shutdown of the laser

With the LaserTec technology HOMAG reaches the highest standards in edge processing. Customers are convinced by the benefits of the procedure.
