The Sentinel guarding system features a laser transmitter and receiver that are mounted to the upper beam of the press brake. A continuous block laser field protects the zone directly below the punch tip allowing the operator to hold the work piece as the tools close at high speed. If an obstruction is detected the machine is automatically stopped.
The Sentinel system can be retrofitted to most existing press brake models and provides a complete safety solution that includes optical protection, monitoring of the press brake control commands and actions, control and monitoring machine safety elements and more.
The block laser field is processed by the receiver and divided into three continuous zones to detect obstructions entering from the front, sides and rear of the tool area. The front zone provides protection forward of the tool while the middle zone protects the area just behind the tip of the punch. The rear zone provides additional protection for the open gaps created when segmented tooling is used.
The laser field is processed by the receiver and divided into two rows of three continuous zones to detect obstructions entering from the front, sides and rear of the tool area. The front zone provides protection forward of the tool while the middle zone protects the area just behind the tip of the punch. The rear zone provides additional protection for the open gaps created when segmented tooling is used. The protective zones are independently and automatically muted to suit different shape work pieces allowing parts to be formed safely at high speed to achieve maximum productivity.
RapidBend technology employs a patented progressive muting process that enables the press brake to close safely at high speed until the tool opening is only 6mm. This reduces the slow speed travel distance to enhance machine productivity. RapidBend is compatible with most synchronised CNC press brakes* and in comparison to other light or laser based systems, RapidBend can reduce machine cycle time by up to two seconds per cycle. This represents a significant saving in operating time and cost.
*FOR RETROFIT APPLICATIONS, RAPIDBEND CAN REDUCE THE MINIMUM SPEED CHANGE POINT TO 6MM, HOWEVER RESULTS MAY VARY DEPENDING ON THE PRESS BRAKE TYPE AND CAPABILITIES. CONSULT YOUR LAZER SAFE RETROFIT DEALER FOR MORE INFORMATION .
Advanced machine monitoring
AutoSense is an automatic monitoring technology that tracks machine operation and performance in real time. AutoSense automatically monitors control commands, motion, direction, speed and stopping performance to maintain a high level of machine and operator protection. AutoSense also guarantees compliance with international safety standards that mandate automatic monitoring of machine overrun and safe speed.
External Device Monitor (EDM)
Sentinel Plus provides the option to connect and monitor up to four external devices such as valve sensors or relays. The EDM response time is configurable and the status of each external device is displayed on the user interface panel in the event of a device failure.
Mounting bracket options
Sentinel is available with two mounting bracket options. A range of vertical lengths are available to suit various machine and tooling applications.
