System Overview
The Lazer Safe Sentinel Plus Press Brake Guarding System is a guarding system designed
for hydraulic press brakes that provides a highly effective solution for both operator
protection and machine productivity.
3.1
Key Benefits
•
Sentinel Plus gives the operator unrestricted access to the tooling area.
•
The operator can hold the work piece as close as 20mm to the bend line and
operate the machine at high speed.
•
Complex shapes can be produced with the "Tray / Box" and "Field Muted" modes of
operation.
•
The Sentinel Plus system continuously monitors the machine speed and stopping
distance in real time.
•
In Normal mode the LZS-005-R block laser detects obstructions as small as 2mm,
allowing a mute point of 2mm.
•
The 2mm mute point is set on the first stroke. The laser guard detects the material
position, and the operator confirms the mute point.
•
Failure detection is performed by real-time monitoring of the process under control.
•
Sentinel Plus also supports a wide range of third party light curtains. The operator
can easily switch between laser guarding or light curtains.
•
Supports non ‘V’ tools with Special Tools Mode.
•
The Sentinel Plus system can be installed either at the time of manufacture or as a
retrofit to a press brake already in service.
Figure 3-1: Sentinel Plus Press Brake Guarding System Key Features
Automatic Mute Point Set-up
The 2mm mute point set-up is automatically initiated on the first
cycle. The system detects the material surface and the operator is
prompted to confirm the mute point via the User Interface Panel. The
system automatically monitors the mute position and detects
changes in tool size and material thickness.
Sentinel User Interface Panel
The 4.3” colour graphics
display makes the system very
simple to operate. A magnetic
backing allows the panel to be
easily moved.
Laser Transmitter (TX)
As the tools close in high speed the
protective zone is progressively muted
while machine deceleration and speed is
monitored. The system provides optical
protection until the opening is 2mm.
Close Proximity Protection
Sentinel Plus gives the operator unrestricted
access to the tooling area. The operator can
hold the work piece as close as 20mm from
the bend line, and still operate the machine
safely in high speed.
Laser Receiver (RX)
The camera receiver features
automatic Tool Alignment to
detect the tool profile for
simple and fast set-up.
Quick Adjust Brackets
The TX and RX can be
quickly moved clear during
tool change, are easily
adjusted and highly tolerant
to machine vibration.
Advanced Monitoring Functions
Sentinel Plus automatically monitors
machine performance in real time.
