Press Brake Guarding
LazerSafe Safeguarding
System for Hydraulic Press Brakes
LazerSafe
is a Machine Safeguarding system for hydraulic press brakes that
provides the most effective solution for operator safety and
machine productivity combined.
The transmitter andreceiver are mounted on the
ram of the press allowing the operator to stay close to the work
piece as the tools close at high speed.
Due to the location and size of the beams,
multiple bends in the material are easily accomplished without
interrupting the laser beams. The muting point is automatically
determined during the
initial test stroke of the machine.
First, the material surface is detected by the
laser, then the operator confirms the LZS-003HS
position by merely pressing the set button. There are no
switches, photoelectrics or proximity switches to adjust. The
mute point position is permanently monitored. A change in the
mute position will be detected and the machine brought to a
stop.
The LazerSafe does not limit the high speed
capability of the slide but still continuously monitors the
speed and stopping distance of the moving member of the machine.
If the crawl speed of
10 mm/sec. is exceeded and/or the stopping distance of 13 mm is
exceeded, LazerSafe will issue a stop command to the machine.
There is no need for a separate stopping performance monitor.

Press Brake Safety With Productivity
Performance
Productivity is greatly enhanced with
LazerSafe as compared to light curtains. Light curtains used on
press brakes usually reduce throughput by 25 to 40 percent.
LazerSafe’s unique bands of laser
light combined with its mounting location on the machine and its
“step-through” bend cycle provides considerably greater
throughput while providing operator safety.
The LazerSafe press brake safety system
permits freedom of handling the work piece while providing
operator protection and real-time monitoring of the bending
process for press brake failures.
- Operates approximately 40% faster per cycle compared to
properly mounted and used light curtains
- Independent speed monitoring through its own encoder
- Provides stop distance monitoring every stroke of
machine to assure the press brake can stop as required.
- Does not require the manufacturer’s machine control to
do any monitoring.
- New LCD menu-driven operator interface panel with
magnetic base provides for easy menu-driven programming,
fast and easy setup, real-time operational mode status,
password
protection for supervisory control, and protective field
status.
- UL listed based on the requirements of ANSI/UL61496
(Type 4 Laser Guarding System) and UL508
- Listed for use in compliance with NFPA79-2002, Clause
11.3.4
- Complex bends achieved with “Tray/Box” and “Field Muted”
modes of operation
- Controls the point of operation through closed-loop
monitoring of speed, direction, position and stopping
distance of the ram
- Optional ability to force machine into slow speed by
command of the generators foot switch called “forcing a
crawl”
- Dual flat bands of continuous laser light detect
obstructions as small as 4 mm while still being vibration
tolerant
- Comprehensive operator protection at close proximity to
the point of operation
- Mute point automatically determined off top of material,
easily set and continuously monitored
- Rear section of laser bands easily muted to ignore back
gauge in “up-close” setups
- Failure detection performed by real-time monitoring of
the process under control
- LazerSafe is within “Class I Laser Product” limits as
defined in IEC 60825
- TUV registered number 08/205/B1-PM01700
- Allows tools to close at high speed, increasing
productivity
